DESCRIPTION
Mobile Terminal, base station and methods within the same
Technical field
The embodiments herein relate to a mobile terminal, a base station and methods within the same. In particular, the achievements in this report refer to manage access to a first channel based on contention and a second channel based on contention.
Background
In systems of wireless communication today are used a number of different technologies, such as Long Term Evolution (LTE), LTE-Advanced, Multiple Access by Division of Code of Broadband (WCDMA), Global System for Mobile communications/Enhanced Data rates for GSM Evolution (GSM/EDGE), Interoperability at the Global Level for Microwave Access (WiMax), or Ultra Mobile Broadband (UMB), just to mention a few possible implementations. A wireless communication system comprises base stations that provide a coverage radius of at least one respective geographical area forming a cell. The definition of cell may also incorporate frequency bands used for transmissions, which means that two different cells may cover the same geographical area but using different frequency bands. The mobile terminals are served in the cells by the base station in question and communicate with the base station in question. The mobile terminals transmit data over an air interface or radio base stations in the transmission of uplink (UL) and base stations transmit data over an air interface or radio to the mobile terminals in the transmission of downlink (DL).
The Publication 6 of the standards of the cooperation project third generation (3GPP) introduced the Uplink-Enhanced (E-UL), also known as Access Packages, High Speed Uplink (HSUPA). Compared with the prior publications, E-UL enhanced the performance of the communications uplink – those from a mobile terminal, i.e., User Computer, to a base station – using the data rates increased, reduced latency and capacity of the system is improved. These improvements were implemented through a new transport channel called the Dedicated Channel Enhanced (E-DCH). In Publication 6 and continuing in Publication 7, however, a mobile terminal can only use the E-DCH in limited circumstances.
Specifically, in the level Control Radio Resource (RRC), a mobile terminal can be in two basic modes of operation, called IDLE mode and CONNECTED mode. In the IDLE mode, the mobile terminal requests a connection RRC before sending any data up-link or responding to a search. In the CONNECTED mode, by contrast the mobile terminal has a connection RRC, and can be in one of several states of service: state of Search Channel Radio Access in the Universal Mobile Telecommunications System (UMTS) (URA_PCH), a state Search Channel Cell (CELL_PCH), a Channel status of a Direct Access Cell (cell_fach states) and state Dedicated Channel Cell (CELL_DCH). The states URA_PCH and CELL_PCH are states of search in which the mobile terminal lies, and only occasionally is activated to check for a search. To send data uplink, the mobile terminal must be moved to the state cell_fach states or CELL_DCH. When you move to the state cell_fach states in Publications 6 and 7, the mobile terminal may send a relatively small amount of data uplink on a channel-based transport in containment called the Channel of Random Access (RACH), but not on the E-DCH; to send data on the E-DCH, the mobile terminal would have to move to the CELL_DCH state, which introduces a delay.
To reduce the delay caused by the state transition, the Publication 8 of the standards of 3GPP allocates a part of resources of E-DCH resources as common, also called resources of E-DCH common, which can be used on a basis of contention by the mobile terminals in the state cell_fach states. Therefore, the mobile terminals in the state cell_fach states with a relatively large amount of data uplink can send those data on the E-DCH using the resources of E-DCH common more than have to make multiple accesses on RACH or switching to CELL_DCH state.
This however comes at the expense of an increase of signaling control uplink. In truth, the base station now broadcasts system information to the mobile terminal that informs them about what to ado access-request can be used to request access of E-DCH, and what resources of E-DCH are available as resources of E-DCH common. Among other disadvantages, this signaling control of DL augmented can delay the signaling of the base station of an information system more crucial.
For example, a base station often broadcasts system information in a series of so-called Blocks of System Information (SIB). Different types of system information are disseminated in different types of SIBS, one after the other in a way by division in time. This process is repeated to continuously provide system information to mobile terminals of a form as needed. Therefore, repeat any delays SIB large dice broadcast of the whole series of SIBS, which, in turn, increases the time between whose any SIB dice, that is to say, the repetition factor of the SIB. If the repetition factor of the SIB is

too big for a SIB with system information crucial, there may be long periods of time in which a mobile terminal can't find, send data uplink, perform a cell update or make a return to a network of circuit-switched, also called return of CS. This type of delays may be caused by signaling of control of DL associated with the release 8 standards of the 3GPP, leading to a reduced performance of the wireless communication system.
The WO2007052971 shows a system of the prior art that transmits resource information of a channel based on contention to a EU.
The WO2009057032 shows a method of communication between a primary station and a secondary station comprising a step of signalling two-channel random access of different types on the basis of a difference of resources for the two channels random access.

The mobile terminal further derives the second preamble access request from the first preamble access request. In addition, the mobile terminal requests access using the second preamble access request or the first preamble access request to access the wireless communication system.
According to some embodiments, the object is achieved furthermore by a mobile terminal for requesting access to a wireless communication system. The mobile terminal comprises a circuit receiver configured to receive system information broadcast indicates directly a first preamble access request for the first channel based on contention and that indirectly indicates the few seconds delay of access request to the second channel based on contention on the basis of the first preamble access request indicated directly. The mobile terminal also comprises a processing circuit configured to derive the second preamble access request from the first preamble access request. The processing circuit is configured also to request access by using the second preamble access request or the first preamble access request to access the wireless communication system.
Indicating the second preamble access request on the basis of, for example, as a function of the first preamble access request indicated directly reduces the amount of data signalled in the system information. In this way, reduces the delay for transmitting system information and improves the performance of the wireless communication system.

Detailed description
Fig. 1 is a general view schematically depicting a wireless communication system, also known as a radio network. In systems of wireless communication today are used a number of different technologies, such as LTE, LTE-Advanced, WCDMA, GSM/EDGE, WiMax, or UMB, just to mention a few possible implementations. The wireless communication system, which includes a base station 12 and one or more other entities 14. The base station 12 provides a communication channel of the uplink 16 for data uplink from mobile terminals individual 10, 10-1, 10-2, ..., 10-N in a group 20 of N mobile terminals, also known appropriately as “users” or “user equipment”. The base station 12 further provides a communications channel for downlink 22 for sending transmissions to mobile terminals 10 – 10-N in the group 20, including signaling control.
It should be understood by those skilled in the art that “mobile terminal” is a term that is not rate-limiting which means any user computer, terminal, wireless device or node e.g. Personal Digital Assistant (PDA), laptop, mobile, sensor, relay, mobile tablets or even a station a small base that communicates within a cell served by the base station 12.
The base station 12 can also be know as for example a Nodeb, a Nodeb evolved (eNB, eNodoB), a base station radio, a base transceiver station, written Base Station Access Point, router, base station, a base station controller, a controller radio network or any other network unit capable of communicating with the mobile terminal 10 within the cell served by the base station 12 depending e.g. of the access technology radio and terminology used.
The base station 12 supports two channels Based on Contention (CB) of the communication channel of the uplink 16, a channel CB legacy, for example, which offers data rates low such as a RACH and a channel CB not a legacy, for example, which offers data rates high such as an E-DCH. Some mobile terminals 10-1
– 10-N, known as mobile terminals legacies, only support channel CB legacy, while others support both CB channels. If the mobile terminal 10 supports both channels, the mobile terminal 10 may select preferentially the channel CB is not legacy to send data uplink. In order to manage the access to both CB channels, the base station 12 broadcasts system information for both CB channels on a control channel of the communication channel downlink 22. Channel-based containment means in the present memory, a channel that can use a lot of mobile terminals without prior coordination. In this way, for a channel based on contention, the base station 12 broadcasts preambles of access request which the mobile terminal 10 randomly selects. In a channel that is not based on containment of the base station 12 first maps a preamble of the access request with the mobile terminal 10 and then transmits the preamble of the access request associated with the mobile terminal 10 to the mobile terminal 10 for use. In particular, the base station 12 broadcasts on the control channel system information that indicates which first preamble access request and second preambles in access-request can be used to request access by using the respective of the CB channels. Each preamble of the access request can be correlated with a particular resource of a channel CB. In this regard, the CB channels share the “space” of the preamble of the access request. The base station 12 may also broadcast system information that indicates which resources of the CB channels are available.
As a point of advantage, the base station 12 broadcasts intelligently system information for the CB channels, in order to limit the amount of signaling of control of the downlink. According to the embodiments in the present memory, in place of broadcast system information to mobile terminals 10 – 10-N which indicates regardless preambles to request access to the respective CB channels, the base station 12 broadcasts system information that indirectly indicates the preambles of request for access to a channel, for example, the channel CB is not legacy, based, for example as a function of the preambles of the access request to the another channel, for example, the channel CB legacy. In the same way, the mobile terminal 10 receives system information that indicates directly the preambles of request for access to a channel, for example channel CB legacy and derives the preambles of the access request to the another channel, for example, the channel CB is not legacy, as a function of the preambles of the access request indicated directly. In some embodiments, the mobile terminal 10 then randomly selects one of the preambles of access request derived, and transmits the preamble of the access request selected by the base station 12 in order to request access to the channel CB is associated, that is to say, the channel is not legacy or the channel legacy. It should be understood that the information system can directly indicate the preambles of the access request channel is not legacy, and to indicate indirectly the preambles of the request of the channel legacy.
The accomplishments described in this report can reduce advantageously the signaling required in Blocks of System Information (SIB) to spread the total amount of resources of E-DCH common around

70% compared with the signaling current. In particular, after the Publication 8 (Publ-8), SIB type 5 (SIB5), which is the kind of SIB that indicates that the preambles can be enlarge substantially due to the settings of E-DCH common. You can configure a total of 32 resources of E-DCH common in a cell. If all these resources are included in SIB5, the size of SIB5 would be increased in 8 segments, where a segment comprises a header and a data field, for example, the data field transports the items of system information are encoded. This would mean that SIB5 may take more than 12 segments, and in turn, would mean that a Block of Information Master of up to 16 segments, SIB type 11 (SIB11) of up to 16 segments, and SIB5 would take more than 50% of the 64 segments available in a frame scheduling window of 1280 seconds. As a result, SIB5 would not be able to be disseminated in less than 640 ms, which means that the repetition factor may need to be increased. However, according to the embodiments of the present memory, the number of segments to broadcast SIB5 may be reduced to less than 3 segments. This means that you can reduce the repetition factor of SIB5. Therefore, to minimize the delay time to transmit the reconfiguration of Carrier Radius (RB) of updates to URA/CELL when you apply, or the delay introduced into the return mechanism of CS. In more detail, the SIB is read by the mobile terminal 10 in different stages. For example, when the mobile terminal 10 is turned on or when the mobile terminal 10 moves from the state CELL_DCH to the state cell_fach states, the mobile terminal 10 needs to acquire the SIBS again. Similarly, when the mobile terminal 10 moves to another cell, they have to be read the new SIB.
The cell update will be the most impacted. The cell update when it moves from a state CELL_DCH to state cell_fach states if the ID is not included or the mobile terminal 10 selects a cell different than that indicated in the reconfiguration of RB. The cell update is also performed when the mobile terminal 10 changes the cell. For E-DCH in mobile terminals in the state cell_fach states and the CELL_DCH state, the Cell Update is also required after a failure of Radio Link (RL). There are other cases in which it requires a cell update.
In addition, in the Publication-10 of the standards of the 3GPP, also known as 4th Generation, is introduced to the return of CS from LTE. This feature may require the mobile terminal 10 to read the SIBS before you start the procedure.
Those skilled in the art will appreciate that while the examples have been described in the context of the standards of 3GPP, these teachings are applicable to a wide range of types of systems, schemes of communication pipeline, etc
Fig. 2 is a schematic flow diagram and an outline of signaling combined represent some achievements in this report.
Step 201. The base station 12 encodes system information to be broadcasted to the mobile terminals within an area covered by the base station 12. The information system is coded so that it will indicate directly the first preamble access request for the first channel based on contention. The second preamble access request to the second channel based on containment are shown indirectly to be indicated on the basis of the first preamble access request indicated. Indirectly in the present memory means to the second preamble access request are derivables from the first preamble access request, for example as a function of the first preamble access request indicated. For example, the preambles of access-request of an E-DCH common is stated as an inverse of the preamble of the access request, for example, the negotiation logic of each bit, of one Channel of Random Access Physical (PRACH) or indicate as not being the preambles of access request in PRACH. The encoding may comprise encoding physical layer.
Step 202. The system information encoded is broadcast to the mobile terminal 10.
Step 203. The mobile terminal 10 that has received the system information broadcast indicates directly the first preamble access request for the first channel based on contention, derives the second preamble access request to the second channel based on containment as a function of the first preamble access request indicated directly.
As a specific example in the context of the specifications of 3GPP, the base station 12 can support CB channels that correspond to the Channel of Random Access (RACH) and Dedicated Channel Enhanced (E-DCH) common. Therefore, the base station 12 broadcasts system information for these channels in a Block of System Information (SIB), this is SIB Type 5. The system information for the RACH is broadcast in SIB5 using the Information Element (IE) “List of System Information PRACH,” while system information for the E-DCH common is broadcast in SIB5 using the IE “System Information for E-DCH common”. A preamble of the access request to be used corresponds to a preamble of PRACH, which is characterized by a sequence of signatures, also known as a signature, a code for randomization and a sub channel.
In some embodiments, the base station 12 in the step 202 can also reduce the signaling control of the downlink broadcasting system information that indicates smartly the available resources of a channel CB. In particular, the processing circuits of the base station 12 can encode in step 203

system information that indicates available resources of a channel CB with respect to other available resources of that channel, for example, with respect to the position in which they indicate other resources available in the information system, rather than indicating each resource independently. In some embodiments, for example, the available resources are indicated in an ordered list and the base station 12 indicates the available resources as a function of its position in the list relative to other resources. The circuit of TX of the base station 12 broadcast this system information in a manner similar to that described above with respect to the information about the ado access-request.
In the same way, the circuit RX of the mobile terminal 10 in various embodiments are configured to receive system information that indicates a first available resource of a channel CB. The processing circuitry of the mobile terminal 10 are configured to derive then the information for a second available resource of the channel CB in the basis for example as a function of the first resource available to them. This may involve, for example, to derive information for the second available resource according to a default rule that defines the second resource as a function of the first resource, for example, as a function of the position of the first resource within an ordered list describing the resources. In various embodiments, the second resource available to the channel CB is correlated with a preamble of the access request selected randomly by the mobile terminal. In such embodiments, the processing circuits are configured to derive information for the second available resource in response to receiving an acknowledgement of receipt of a positive corresponding to the preamble selected, and then transmit data on the uplink channel CB using the second available resource. It should be noted that the same applies to a third resource, a fourth resource, and so on.
Step 204. At some point after receiving this system information, the mobile terminal 10 requests access to one supported or preferred, of the CB channels, the first or the second channel based on containment, by randomly selecting one of the first or second preamble access request associated with that channel and transmitting the preamble selected by the base station 12.
Step 205. The base station 12 that has received the preamble of the access request transmitted, performs a management of contention for the channel CB partner.
Step 206. The base station 12 transmits or signals on the communications channel downlink 22 if the base station acknowledges or denies the request of the mobile terminal for access to that channel.
Step 207. If the mobile terminal 10 receives an acknowledgment of receipt is positive, the mobile terminal 10 proceeds by sending uplink in any resource available channel CB partner is correlated with the preamble of the access request selected and recognized.
Fig. 3 is a schematic flow diagram depicting embodiments of a method in the base station 12 for managing access to the first channel based on contention, and the second channel based on contention.
Step 301. The base station 12 encodes system information that indicates directly a first preamble access request for the first channel based on contention and that indirectly indicates the few seconds delay of access request to the second channel based on contention on the basis of the first preamble access request indicated directly. In some embodiments, the second preamble access request are derivables as a function of the first preamble access request.
With examples, variations and modifications described above, those skilled in the art will also appreciate that the base station 12 in the present memory is configured generally to perform the method illustrated in Fig. 3. In Fig. 3, the processing in the base station 12 includes encoding an information system which indicates directly a preamble statement of request for access to a channel of the uplink based on containment, and that indirectly indicates the preambles of access request to another channel of the uplink based on contention on the basis for example as a function of the preambles indicated directly. In some embodiments the first channel based on containment corresponds to a channel random access, RACH. In some embodiments the second channel based on containment corresponds to a Dedicated Channel Enhanced, E-DCH, common. In some embodiments the system information encoded is included in a Block of System Information type 5, SIB5.
In more detail, the embodiments herein reduce the number of segments used in SIB5 to broadcast the IE “System Information for E-DCH common” that defines the parameters of resources of E-DCH common. For this purpose, it proposes a new encoding for the IE contained in the IE “System Information for E-DCH Common” within SIB5. The IE “System Information for E-DCH Common” is a IE optional included in SIB5. The table below presents the current encoding for FDD the IE “System Information for E-DCH Common” as it is captured in the Technical Specification (TS) 25.331 section 10 version 10.0.0 of the 3GPP.

MP means to Present Mandatory and OP represents Optional. An IE that is Present Necessarily always needs to be included and have a value while the value of an si can optionally be present or not. MD represents Mandatory By Default. When IE is set as Mandatory by Default, you always need a value for this IE, and mentions a value for the particular defect.
The embodiments herein propose modifications to some of these IE, as described in more detail below.
In some embodiments, the first preamble access request corresponding to the preamble Channel Random Access Physical, PRACH, characterized by a sequence of signatures, a code of randomization, and a sub channel. In this way, the first preamble access request can correspond to preambles of PRACH to RACH and the second preamble access request can correspond to preambles of PRACH for preamble AND UL-or E-DCH.
The IE modified are:
>>Control parameters preamble of PRACH for Uplink Enhanced
The IE of control parameters preamble of PRACH for E-UL can understand signatures available, code numbers for randomization of the preamble, and Numbers of Sub-Channels Available.
Signatures Available
This is an IE of a bit string and each bit indicates whether used or not used a signature. The signatures configured for RACH and included in the IE “Signature Available” present in the IE “Information of a PRACH (for RACH)”. These signatures are not to be used for Uplink Enhanced in cell_fach states and Idle Mode. The IE “Information of a PRACH (for RACH)” is included in the IE “List of System Information PRACH” that is transported in SIB5. “List of System Information PRACH”, “Information of a PRACH (for RACH)” and “Signatures” Available are IE present necessarily. Therefore, always be included in SIB5. In this manner, in some embodiments, the first preamble access request is indicated in an information element denoted as Channel information, Random Access-Physical, PRACH, comprised in a list of system information PRACH transported in a Block of System Information type 5, SIB5.
The IE “Signature Available” included in the IE “Parameters of control preamble of PRACH for Uplink Enhanced” is also a present value necessarily; however, in the embodiments herein this IE is optional and takes a default value. This default value can be the same or a function of another IE, for example, the “Signature Available” present in the IE “Information of a PRACH (for RACH)”.
As an example, the default value in various embodiments is an operation function “REVERSE” or “NO” from the string values of the bits included in “Signatures” Available present in the IE “Information of a PRACH (for RACH)”.
An illustrative example is presented to clarify the concept. If the value of the IE “Signature Available” included in the IE “Information of a PRACH (for RACH)” is: 1111111100000000, then the default value of the IE “Signature Available” contained in the IE “System Information for E-DCH Common” would be the operation is the bitwise inverse of (1111111100000000) which is equal to 0000000011111111. Therefore, the IE “signature available” is set to mandatory default (MD) and the semantics of the description I would say that the default value is the bit string inverse indicated in the IE “Available Signature” in the IE “Information of a PRACH (for RACH)”. In other words, the signatures that are available for Uplink Enhanced in cell_fach states are those firms that are not used for RACH, unless they are present IE.
In so doing, the base station 12 deletes include this IE in the IE “Parameters of control preamble of PRACH for Uplink Enhanced” and therefore reduces the signaling control of the downlink. A mobile terminal 10 that does not receive such an IE nevertheless sets the IE to a default value described above. If the IE is present, the values listed overwrite the default value. In this manner, in some embodiments, the first preamble access request for the first channel based on contention are indicated as signatures available in the information element Information of the PRACH and the second preamble access request to the second channel based on contention are indicated indirectly as a function of the first

ado access-request in an information element denoted as signatures available in an item of information indicating control parameters preamble of PRACH for uplink enhanced.
Code number of randomization of the preamble
This IE is also included in the IE “Information of a PRACH (for RACH)”. The embodiments herein teach that the code of randomization for the E-DCH common is the same as that of the RACH, at least by default. If different, the new code Number of aletorización of preamble in different realizations is a function of the Number of code randomization of the preamble present in the IE “Information of a PRACH (for RACH)”. Therefore, this IE in some embodiments is MD and by default equal to the IE “code Number for randomization of the preamble indicated in the IE “Information of a PRACH (for RACH)” and another mode is a function of the IE “code Number for randomization of the preamble indicated in the IE “Information of a PRACH (for RACH)”.
As in the previous case, the base station 12 refrains from including this IE in the IE “Parameters of control preamble of PRACH for Uplink Enhanced” and therefore reduces the signaling control of the downlink. A mobile terminal 10 that does not receive such an IE nevertheless sets the IE to a default value described above. If the IE is present, the values listed overwrite the default value. In this manner, in some embodiments a number of code randomization of the preamble of the second preamble access request is a code for randomization of the preamble of the first preamble access request. Alternatively, the code number of the scrambling of the preamble of the second preamble access request may be a function of the code of randomization of the preamble of the first preamble access request.
Number of Sub-Channel Available
This IE is a bit string. Each bit indicates availability for a sub channel, where the sub channels are numbered from “sub channel 0” to “sub channel 11”. The value 1 of a bit indicates that the sub channel is available and the value 0 indicates that it is not available.
This IE is also included in the IE “Information of a PRACH (for RACH)”. This IE in some embodiments is also set to MD. The required value by default is a function of the IE “Information of a PRACH (for RACH)”.
For example, this IE can be set equal to the IE “Number of Sub-Channel Available” indicated in the IE “Information of a PRACH (for RACH)”. In another approach, the default value can be the INVERSE function (or NOT) of the IE “Number of Sub-Channel Available” indicated in the IE “Information of a PRACH (for RACH)”.
As in the previous case, the base station 12 refrains from including this IE in the IE “Parameters of control preamble of PRACH for Uplink Enhanced” and therefore reduces the signaling control of the downlink. A mobile terminal 10 that does not receive such an IE nevertheless sets the IE to a default value described above. If the IE is present, the values listed overwrite the default value. In this manner, in some embodiments a number of code, sub channel available to the second preamble access request is set to be equal, the inverse or a function ‘not’ of a number of sub available channel indicated in the information element designated information of the PRACH.
In some embodiments, the base station 12 also reduces the signaling control of downlink spreading intelligent system information that indicates available resources of a channel CB, for example, the channel CB is not legacy.
Let's consider a specific example in the specifications of the 3GPP, by which the resources available include a combination of a time interval of command channel of power control, a channel coding command of power control and the like, with each component of a resource available that indicates with respect to a corresponding component of another resource available to them.
In some embodiments the base station 12 encodes system information that indicates a second available resource of the second channel based on containment with respect to a first available resource of the second channel based on contention. The second available resource in some embodiments can be indicated in an ordered list of resources as a function of a position of the first available resource in the ordered list.
The ordered list in some embodiments can define a resource of Dedicated Channel Enhanced (E-DCH) common. Each Resource E-DCH can be defined by an item of information Soffset, an item of information of code number of Control Channel Dedicated Physical Fractional (F-DCPH) and an information element information Channel Indicator Acknowledgement of Receipt of Request Automatic Repeat Hybrid of E-DCH (E-HICH) E-DCH common.
>>List of Resource Configuration information of E-DCH Common
This IE is a list that includes all of the resources of E-DCH common. You can include in this list a maximum of 32 resources of E-DCH common. For each resource E-DCH common defined, it is defined by the following IE:

>>>Soffset
This IE is an IE MARKER whose value ranges between 0 and 9. This value indicates the specific interval within the F-DPCH in which the control commands power is provided to a code of F-DPCH concrete.
Instead of being MP, this IE is set as MD in a number of realizations. If the IE is not present, “Soffset” takes a default value. The default value is a function of the position of the resource of E-DCH common within the list, a function of the value “Soffset” from a case of resource E-DCH common prior or a function of the position of the resource of E-DCH common and the value “Soffset” from a case of resource E-DCH common prior. The first resource of E-DCH common defined would occupy a position 0 (or 1). The second resource of E-DCH common defined would occupy a position 1 (or 2). Similar reasoning would apply with the other resources defined.
One concrete realization would be, for example, if the value is “Soffset” for the first case of the appeal of E-DCH common takes a default value and the rest of the resources of E-DCH common take a value related to the last case.
For example, we present below a simple formula to set default values for each resource E-DCH common defined.
Soffset = (position of list of resources of E-DCH common + offset) mod 10
where “offset” is the value of the last event of the IE “Soffset”. If the IE “Soffset” was not present in the first case, the “offset” is equal to zero.
“position of list of resources of E-DCH common” indicates the number of resource Configuration information of E-DCH common by order of appearance. The value of the “position list of resources E-DCH common” may be zero (or one) for the first case. If the IE is present, the value pointed to overwrite the default value.
In some embodiments the position of the second available resource in the ordered list is defined by a default value in the item of information Soffset, whose default value is a function of the position of the second available resource within the ordered list, a function of a “Soffset” a paramount resource available prior to or a function of the position of the second available resource and an offset value. The offset value is a value Soffset of the first available resource.
>>>Code number (F-DPCH
This IE indicates the code to be used for the F-DPCH.
Instead of being MP, this IE is optional, conditioned to a value.
If it is applied to the encoding presented to the Soffset, potentially, only need three cases in the code number of F-DPCH, once for each of the 10 resources of E-DCH common. Therefore, in the best settings, you only need to be present in three cases.
Therefore, this IE is a number of realizations was set as conditional on value (CV) so that this IE is present mandatory for the first occurrence. Alternatively, you should be present is mandatory for the first occurrence or if the default value is equal to zero. Otherwise, this IE is optional. In addition, if this IE is not present, the value is equal to the last occurrence of this IE.
If the IE is present, the value signaled on writes the default value.
In this manner, in some embodiments the information element number of a code of F-DPCH can be the same for a maximum number of ten resources of E-DCH common.
>>>>Information in E-HICH
Information E-HICH contains two IE additional. The changes in this EI would impact on the Publication 6 and Publication 7 of the standards of 3GPP. In order to avoid impacts on versions more early, you can use a new IE in your location: “Information in E-HICH for E-DCH common”. You only need two IE since this feature only applies to FDD. In some embodiments the information element Information E-HICH for E-DCH common is defined by a code of pipeline, and a sequence of signatures. A default value of the sequence of signatures may be a function of the position of the second available resource within the ordered list, a function of a value of “Sequence Signatures” of a first resource is available prior to or a function of the position of the second available resource and the value of “Sequence Signatures” of a first resource is available prior.

This IE can be set as an IE conditional on value (CV) so that the IE is mandatory only for the first case and optional for the rest of them. If this IE is not present, the value is equal to the last occurrence of this IE. In this manner, in some embodiments the code of the pipeline of the second available resource may be equal to a code pipeline of the first available resource.
If the IE is present, the value pointed to overwrite the default value.
Sequence of signatures
The value of this IE is a number between 0 and 39. This IE is set as MD in various projects. If the IE is not present, “Sequence signatures” takes a default value.
The default value is a function of the position of the resource of E-DCH common within the list, a function of the value of “Sequence Signatures” from a case of resource E-DCH common prior or a function of the position of the resource of E-DCH common and the value of “Sequence Signatures” from a case of resource E-DCH common prior. The first resource of E-DCH common defined would occupy the position 0 (or 1). The second resource of E-DCH common defined would occupy position 1 (or 2). Similar reasoning would apply with the other resources defined. A concrete realization may be, for example, if the value of “Sequence Signatures” for the first case of the appeal of E-DCH common take a default value and the rest of the resources of E-DCH common to take a value function of the last case in the IE.
For example, we present below a simple formula to set default values for each resource E-DCH common in the that the IE is not present.
Sequence Signatures = (position of list of resources of E-DCH common + offset) mod 40 where “offset” is the value of the last occurrence of the IE “Sequence Signatures”. If “Sequence Signatures” was not present in the first case, the “offset” is equal to zero.
“position of list of resources of E-DCH common” indicates the number of resource Configuration Information of E-DCH common by order of appearance. The value of the “position list of resources E-DCH common” is zero (or one) for the first case.
If the IE is present, the value pointed to overwrite the default value.
>>>Information of code of DPCH uplink (for E-HCIH common)
Code number randomization
Code number randomisation is a value to this MP. This IE take a number of bits that are relatively large for each resource E-DCH common. This IE is changed in some realizations conditional on value (CV) in its place, avoiding to include such a number of bits large resource of E-DCH common set up.
Conditional on a value would mean that this IE is present mandatory for the first occurrence. Otherwise, this IE is optional. In addition, if this IE is not present, the value of the IE is a function of the latter case. For example, it could be a function of the position of the resource of E-DCH common within the list of resources of E-DCH common a function of the value Information “of the code of DPCH uplink for E-DCH common” a case of the appeal of E-DCH common prior or a function of the position of the resource of E-DCH common and the value of Information “code of DPCH uplink for E-DCH common” a case of the appeal of E-DCH common prior.
The following formula illustrates how you can set the values by default if the IE is not included:
Code number of randomization = position of list of resources of E-DCH common + offset, where "offset" is the value of the last occurrence of the IE “code Number randomization”. If “scrolling” was not present at the first event or occurrence, “offset” is equal to zero.
"position of list of resources of E-DCH common" indicates the number of Configuration Information of the resource of E-DCH common by order of appearance. The value of the “position list of resources E-DCH common” is zero (or 1) for the first case. If the IE is present, the value pointed to overwrite the default value.
In this manner, in some embodiments the second available resource is defined by a value in an information element of a code of randomization is a Control Channel Dedicated Physical uplink. The value can be a function of the position of the second available resource within the ordered list of resources of E-DCH common a function of a value in an information element of a code of randomization is a Control Channel Dedicated Physical uplink of a first resource is available prior to or a function of the position of the second available resource and a value-of-Information “code of DPCH uplink for E-DCH common” in the information element of a code of randomization is a Control Channel Dedicated Physical uplink of the first resource available to them prior.
>>Information of the E-DPDCH
E-TFCI of minimum set of E-DCH
This IE is mandatory default. If you omit this IE, means that there is a set E-TFCI to a minimum.
In the case of E-DCH in cell_fach states and Idle Mode, the UE will send always your message, especially messages
5 of CCCH. Otherwise, the EU will be blocked and, potentially, the EU will drop. It seems obvious that for E-DCH in cell_fach states and Idle Mode, the E-TFCI of minimum set of E-DCH shall be included always and it will be necessary that there should be a number above zero (0-Index of E-TFCI only would allow the EU to send the Scheduling Information).
Therefore, the semantic description can be modified so that for cell_fach states, and Idle Mode (or to
10 Uplink Enhanced in cell_fach states and Idle Mode), if the IE is not included, the E-TFCI of minimum set of E-DCH is set to a defined value. The only restriction for this value is that the value belongs to the set of values defined in the table of E-TFCI. The particular table to be used is indicated in the IE “table of contents table of E-TFCI” included in the IE “Information of E-DPDCH”. As mentioned before, the value of E-TFCI of zero only allows the UE to transmit the Scheduling Information. Therefore, the value of E-TFCI minimum
15 reasonable so that the UE can transmit control data of higher layers or user is the value of E-TFCI 1.
If the IE is present, the values listed overwrite the default value.
Applying the encoding suggested before, the structure of the IE “Parameters of control preamble of PRACH for Uplink Enhanced” and other IE involved would result in shown below. The IE affected
20 are underlined and the IE are not affected are defined in reference to the Technical Specification (TS) 25.331 section 10 version 10.0.0 of 3GPP: the IE information system of E-DCH common are illustrated in the table below

The IE “Information E-DPCH” and the “code of DPCH uplink for E-DCH Common” would not change compared with the first solution.
5 The improvement of coding of each IE present in “System Information for E-DCH Common” is independent of other IE.
Processing alternatively or additionally includes encoding system information that indicates available resources of a channel of the uplink based on containment with respect to other available resources of that channel. In any case, the processing finally includes disseminating system information to one or more
10 mobile terminals 10.
Step 302. The base station 12 transmits the system information encoded at the mobile terminals, for example, the mobile terminal 10.
Fig. 4 is a block diagram which represents the base station 12 according to embodiments herein. To support the signaling link control anterior descending, the base station 12 in some 15 embodiments includes one or more antennas for transmission/reception 402, along with the circuit transmitter (TX) 404 and the circuit receiver (RX) 401 is associated, respectively, and additionally includes one or more processing circuits 403. The processing circuit 403 is configured to encode system information that indicates one preamble request for access to one of the CB channels and that indirectly indicates the

a few preambles request for access to the other CB on the basis of, for example, as a function of the preambles indicated directly. This may involve, for example, to remove the coding that would indicate directly that certain preambles of access request. The circuit TX 404 is then configured to broadcast the system information encoded to the mobile terminals 10 – 10-N, via the transmit antennas 402.
In some embodiments, the processing circuit 403 of the base station 12 encodes system information that indicates available resources of a channel CB with respect to other available resources of that channel, for example, with respect to a position in which you indicate other resources available in the information system, rather than indicating each resource independently. In some embodiments, for example, the available resources are indicated in an ordered list, and the processing circuit 403 encodes the system information to indicate the available resources as a function of its position in the list relative to other resources. The circuit TX 404 then broadcasts this information system in the same way as described above.
In this way, the base station 12 for managing access to the first channel based on contention, and the second channel based on contention comprises the processing circuit 403. The processing circuit 403 is configured to encode system information that indicates directly a first preamble access request for the first channel based on contention and that indirectly indicates the few seconds delay of access request to the second channel based on contention on the basis of the first preamble access request indicated directly. The base station 12 also includes the circuit transmitter 404 configured to broadcast the system information encoded at the mobile terminals.
In some embodiments the first channel based on contention may correspond to a channel random access, RACH, and in some embodiments, the second channel based on containment corresponds to a Dedicated Channel Enhanced, E-DCH, common. In some embodiments, the second preamble access request can be derived as a function of the first preamble access request. In some embodiments the system information encoded may be included in an Information Block type 5, SIB5.
In some embodiments, the first preamble access request may correspond to a preamble Channel Random Access Physical, PRACH, characterized by a sequence of signatures, a code of randomization, and a sub channel. In some embodiments, the first preamble access request can be indicated in an information element designated as Channel information, Random Access-Physical, PRACH, comprised in a list of system information PRACH transported in a Block of System Information type 5, SIB5. The first preamble access request for the first channel based on containment can be indicated in some embodiments as signatures available in the information element information of the PRACH and the second preamble access request to the second channel based on contention are indicated indirectly as a function of the first preamble access request in an information element designated as the signatures available in an item of information designated control parameters preamble of PRACH for uplink enhanced. In some embodiments a number of code randomization of the preamble of the second preamble access request may be a code for randomization of the preamble of the first preamble access request. In some embodiments a number code for randomization of the preamble of the second preamble access request may be a function of the code of randomization of the preamble of the first preamble access request. In some embodiments the processing circuit 403 may be configured to set a number of sub available channel of the second preamble access request to be equal, the inverse or a function ‘not’ of a number of sub available channel indicated in the information element designated information of the PRACH.
In some embodiments the processing circuit 403 may further be configured to encode system information that indicates a second available resource of the second channel based on contention regarding the first available resource of the second channel based on contention. In some embodiments the second available resource may be indicated in an ordered list of resources as a function of a position of the first available resource in the ordered list. In some embodiments the ordered list of resources you can define resources Dedicated Channel Enhanced, E-DCH, common, each Resource E-DCH is defined by an item of information Soffset, an item of information of code number of Control Channel Dedicated Physical Fractional, F-DPCH, and a Channel information of the Indicator of Acknowledgement of Receipt of Application of Auto-Repeat Hybrid of E-DCH, E-HICH, to an information element E-DCH common. In some embodiments, the position of the second available resource in the ordered list can be defined by a default value in the item of information Soffset. The default value can be a function of the position of the second available resource within the ordered list; a function of a “Soffset” from a first available resource consent; or a function of the position of the second available resource and an offset value. The offset value may be a value Soffset of the first available resource. In some embodiments, the information element number of a code of F-DPCH can be the same for a maximum of ten resources of E-DCH common. In some embodiments the information of the E-HICH to an information element E-DCH common can be defined by a code of pipeline, and a sequence of signatures. A default value of the sequence of signatures may be a function of the position of the second available resource within the ordered list; a function of a value of “Sequence Signatures” of a first available resource consent; or a function of the position of the second available resource and the value of “Sequence Signatures” of a first resource is available prior. In some embodiments, a code pipeline of the second available resource may be equal to a code pipeline

the first resource available. In some embodiments the second available resource may be defined by a value in an information element of a code of randomization is a Control Channel Dedicated Physical uplink. The value can be a function of the position of the second available resource within the ordered list of resources of E-DCH common; a function of a value in an information element of a code of randomization is a Control Channel Dedicated Physical uplink of a first resource available to them prior;
or a function of the position of the second available resource and a value-of-Information “code of DPCH uplink for E-DPC common” in the information element of a code of randomization is a Control Channel Dedicated Physical uplink of the first resource available to them prior.
Those skilled in the art will also appreciate that the various “circuits” described may refer to a combination of analog and digital circuits and/or one or more processors configured with software and/or microprogramas, for example, stored in memory, which, when executed by one or more processors, act as described above. One or more of these processors, as well as the other digital hardware, may be included in a single integrated circuit, application specific (ASIC) or different processors and different digital hardware may be distributed between several separate components, whether they are packaged or assembled individually in a system in an integrated circuit (SoC).
Fig. 5 is a schematic flow diagram depicting embodiments of a method in the mobile terminal 10 to request access to the wireless communication system. Those skilled in the art will appreciate that a mobile terminal 10 in the present memory is configured in the same way to perform the(the) method(s) illustrated(s) in Fig. 5.
Step 501. The mobile terminal 10 receives system information broadcast indicates directly a first preamble access request for a first channel based on containment and which indicates indirectly a few seconds preambles request for access to a second channel based on contention. The second preamble access request is indicated indirectly on the basis of the first preamble access request indicated directly. In this way, the processing in the mobile terminal 10 includes a receive system information that indicates directly the first preamble access request to the first channel of the uplink based on containment and indirectly indicates the second preamble access request to the second channel of the uplink based on containment.
Step 502. The mobile terminal 10 derives the second preamble access request from the first preámbulos access-request. In this way, the processing continues by deriving the preambles of the access request to the second channel of the uplink based on the containment on the basis of, for example, as a function of, the preambles indicated directly.
Step 503. The mobile terminal 10 then requests access using the second preamble access request or the first preamble access request to access the wireless communication system. For example, a second preamble access-request can be transmitted to request access to the second channel of the uplink based on containment. The processing may further include selecting randomly one of the preambles of access request derived. In some embodiments, the mobile terminal 10 randomly selects one of the preambles of request for access and transmits the preamble of the access request selected randomly.
The mobile terminal 10 may also be configured to generally carry out a processing, which may overlap the derivation of the preambles of access request, that includes receiving system information that indicates a first available resource of the second channel of the uplink based on containment. The processing may optionally include in some embodiments randomly select a preamble of the access request that corresponds to a second available resource of the second channel of the uplink based on containment, to transmit the preamble selected, and to receive an acknowledgement of receipt positive. Whether performed or not in response to this optional step, the processing comprises deriving system information for a second available resource of the second channel of the uplink based on the containment on the basis of, for example, as a function of the first resource available. Finally, the processing in the different realizations concludes with the transmission of data in uplink in the second channel of the uplink based on containment using the second available resource. In this way, the mobile terminal 10 may randomly select one of the preambles of request for access and transmitting preamble of access request is selected randomly.
In some embodiments the first channel based on containment corresponds to a channel random access, RACH. In some embodiments the second channel based on containment corresponds to a Dedicated Channel Enhanced, E-DCH, common. In some embodiments the system information received is included in a Block of System Information type 5, SIB5.
In more detail, the embodiments herein reduce the number of segments used in SIB5 to broadcast the IE “System Information for E-DCH Common” that defines the parameters of resources of E-DCH common. For this purpose, it proposes a new encoding for the IE contained in the IE “System Information for E-DCH Common” within SIB5. The IE “System Information for E-DCH Common” is a IE optional included in SIB5.

The accomplishments in this report propose amendments to these EI, as detailed later.
In some embodiments, the first preamble access request corresponding to the preamble Channel Random Access Physical, PRACH, characterized by a sequence of signatures, a code of randomization, and a sub channel.
>>Control parameters preamble of PRACH for Uplink Enhanced
IE that includes signatures available, code numbers for randomization of the preamble and Number of Sub-Channel Available.
Signatures Available
This is an IE of a bit string and each bit indicates whether used or not used a signature. The signatures configured for RACH and included in the IE “Signature Available” present in the IE “Information of a PRACH (for RACH)”. These signatures are not to be used for Uplink Enhanced in cell_fach states and Idle Mode. The IE “Information of a PRACH (for RACH)” is included in the IE “List of System Information PRACH” that is transported in SIB5. “List of System Information PRACH”, “Information of a PRACH (for RACH)” and “Signatures” Available are IE present necessarily. Therefore, always be included in SIB5. In this manner, in some embodiments, the first preamble access request is indicated in an information element designated as Channel information, Random Access-Physical, PRACH, comprised in a list of system information PRACH transported in a Block of System Information type 5, SIB5.
The IE “Signature Available” contained in the IE “Parameters of control preamble of PRACH for Uplink Enhanced” is also a present value necessarily; however, in the embodiments herein this IE is optional and takes a default value. This default value is the same or a function of another IE, for example, the “Signature Available” present in the IE “Information of a PRACH (for RACH)”.
As an example, the default value in various embodiments is an operation function “REVERSE” or “NO” from the string values of the bits included in “Signatures” Available present in the IE “Information of a PRACH (for RACH)”.
We present an illustrative example to clarify the concept. If the value of the IE “Signature Available” included in the IE “Information of a PRACH (for RACH)” is: 1111111100000000, then the default value of the IE “Signature Available” contained in the IE “System Information for E-DCH Common” would be the operation is the bitwise inverse of (1111111100000000) which is equal to 0000000011111111.
Therefore, the IE “signature available” is set to mandatory default (MD) and the semantics of the description I would say that the default value is the bit string inverse indicated in the IE “Signature Available” in the IE “Information of a PRACH (for RACH)”. In other words, the signatures that are available for Uplink Enhanced in cell_fach states are those firms that are not used for RACH, unless they are present IE.
In so doing, the base station 12 deletes include this IE in the IE “Parameters of control preamble of PRACH for Uplink Enhanced” and therefore reduces the signaling control of the downlink. The mobile terminal 10 can not receive such an IE nevertheless sets the IE to a default value described above. If the IE is present, the values listed overwrite the default value. In this way, in some embodiments, the first preamble access request for the first channel based on contention are indicated as signatures available in the information element information of the PRACH and the second preamble access request to the second channel based on contention are indicated indirectly as a function of the first preamble access request in an information element designated as the signatures available in an information element parameters control of preamble of the PRACH is designated for uplink enhanced.
Code number of randomization of the preamble
This IE is also included in the IE “Information of a PRACH (for RACH)”. The embodiments herein teach that the code of randomization for the E-DCH common is the same as that of the RACH, at least by default. If different, the new code Number of aletorización of the preamble in number of realizations is a function of the Number of code randomization of the preamble present in the IE “Information of a PRACH (for RACH)”. Therefore, this IE is MD in some embodiments, and by default equal to the IE “code Number for randomization of the preamble indicated in the IE “Information of a PRACH (for RACH)” and another mode is a function of the IE “code Number for randomization of the preamble indicated in the IE “Information of a PRACH (for RACH)”.
As in the previous case, the base station 12 may refrain from including this IE in the IE “Parameters of control preamble of PRACH for Uplink Enhanced” and therefore reduces the signaling control of the downlink. A mobile terminal 10 that does not receive such an IE nevertheless sets the IE to a default value described above. If the IE is present, the values listed overwrite the default value. In this manner, in some embodiments a number of code randomization of the preamble of the second preamble access request is a code for randomization of the preamble of the first preamble access request.

Alternatively, the code number of the scrambling of the preamble of the second preamble access request may be a function of the code of randomization of the preamble of the first preamble access request.
Number of Sub-Channel Available
This IE is a bit string. Each bit indicates availability for a sub channel, where the sub channels are numbered from “sub channel 0” to “sub channel 11”. The value 1 of a bit indicates that the sub channel is available and the value 0 indicates that it is not available.
This IE is also included in the IE “Information of a PRACH (for RACH)”. This IE is also set to MD in some embodiments. The default value for mandatory is a function of the IE “Information of a PRACH (for RACH)”.
For example, this IE can be set equal to the IE “Number of Sub-Channel Available” indicated in the IE “Information of a PRACH (for RACH)”. In another approach, the default value can be the INVERSE function (or NOT) of the IE “Number of Sub-Channel Available” indicated in the IE “Information of a PRACH (for RACH)”.
As in the previous case, the base station 12 may refrain from including this IE in the IE “Parameters of control preamble of PRACH for Uplink Enhanced” and therefore reduces the signaling control of the downlink. A mobile terminal 10 that does not receive such an IE nevertheless sets the IE to a default value described above. If the IE is present, the values listed overwrite the default value. In this manner, in some embodiments a number of sub available channel of the second preamble access request is set to be equal, the inverse or a function ‘not’ of a number of sub available channel indicated in the information element designated information of the PRACH.
In some embodiments, the base station 12 also reduces the signaling of downlink spreading intelligent system information that indicates available resources of a channel CB, for example, the channel CB is not legacy.
Let's consider a specific example in the specifications of the 3GPP, by which the resources available include a combination of interval-time command channel of power control, a channel coding command of power control and the like, with each component of a resource available that indicates with respect to a corresponding component of another resource available to them.
In some embodiments the mobile terminal 10 receives system information that indicates a second available resource of the second channel based on containment with respect to a first available resource of the second channel based on contention. The second available resource may be indicated in some realizations in an ordered list of resources as a function of a position of the first available resource in the ordered list.
The ordered list in some embodiments can define a resource of Dedicated Channel Enhanced (E-DCH) common. Each Resource E-DCH can be defined by an item of information Soffset, an item of information of code number of Control Channel Dedicated Physical Fractional (F-DPCH) and an information element information Channel Indicator Acknowledgement of Receipt of Request Automatic Repeat Hybrid of E-DCH (E-HICH) E-DCH common.
>>List of Resource Configuration information of E-DCH Common
This IE is a list which contains all of the resources of E-DCH common defined. You can include in this list a maximum of 32 resources of E-DCH common. For each resource E-DCH common defined, it is defined by the following IE:
>>>Soffset
This IE is an IE MARKER whose value ranges between 0 and 9. This value indicates the specific interval within the F-DPCH in which the control commands power is provided to a code of F-DPCH concrete.
Instead of being MP, this IE is set in different realizations as MD. If the IE is not present, “Soffset” takes a default value. The default value is a function of the position of the resource of E-DCH common within the list, a function of the value “Soffset” from a case of resource E-DCH common prior or a function of the position of the resource of E-DCH common and the value “Soffset” from a case of resource E-DCH common prior. The first resource of E-DCH common defined would occupy the position 0 (or 1). The second resource of E-DCH common defined would occupy position 1 (or 2). Similar reasoning would apply with the other resources defined.
One concrete realization would be, for example, if the value is “Soffset” for the first case of the appeal of E-DCH common takes a default value and the rest of the resources of E-DCH common take a value related to the last case.
For example, we present below a simple formula to set default values for each resource E-DCH common defined.

Soffset = (position of list of resources of E-DCH common + offset) mod 10
where “offset” is the value of the last event of the IE “Soffset”. If the IE “Soffset” was not present in the first case, the “offset” is equal to zero.
“position of list of resources of E-DCH common” indicates the number of resource Configuration Information of E-DCH common by order of appearance. The value of the “position list of resources E-DCH common” may be zero (or one) for the first case.
If the IE is present, the value pointed to overwrite the default value.
In some embodiments the position of the second available resource in the ordered list is defined by a default value in the item of information Soffset, whose default value is a function of the position of the second available resource within the ordered list, a function of a “Soffset” from a first resource is available prior to or a function of the position of the second available resource and an offset value. The offset value is a value Soffset of the first available resource.
>>>Code number (F-DPCH
This IE indicates the code to be used for the F-DPCH.
Instead of being MP, this IE is optional, conditioned to a value.
If it is applied to the encoding presented to the Soffset, potentially, only need three cases in the code number of F-DPCH, once for each of the 10 resources of E-DCH common. Therefore, in the best settings, you only need to be present in three cases.
Therefore, this IE is in different realizations fixed as conditional on value (CV) so that this IE is present mandatory for the first occurrence. Alternatively, you should be present is mandatory for the first occurrence or if the default value is equal to zero. Otherwise, this IE is optional. In addition, if this IE is not present, the value is equal to the last occurrence of this IE.
If the IE is present, the value pointed to overwrite the default value.
In this manner, in some embodiments the information element number of a code of F-DPCH can be the same for a maximum number of ten resources of E-DCH common.
>>>>Information in E-HICH
Information E-HICH contains two IE additional. Changes in this EI would impact on the Publication 6 and Publication 7 of the standards of 3GPP. In order to avoid impacts on versions more early, you can use a new IE in your location: “Information in E-HICH for E-DCH common”. Only would need two IE since this feature only applies to FDD. In some embodiments the information element Information E-HICH for E-DCH common is defined by a code of pipeline, and a sequence of signatures. A default value of the sequence of signatures may be a function of the position of the second available resource within the ordered list, a function of a value of “Sequence Signatures” of a first resource is available prior to or a function of the position of the second available resource and the value of “Sequence Signatures” of a first resource is available prior.
>>>Information in E-HICH for E-DCH common
Code pipe
This IE can be set as an IE conditional on value (CV) so that the IE is mandatory only for the first case and optional for the rest of them. If this IE is not present, the value is equal to the last occurrence of this IE. In this manner, in some embodiments the code of the pipeline of the second available resource may be equal to a code pipeline of the first available resource.
If the IE is present, the value pointed to overwrite the default value.
Sequence of signatures
The value of this IE is a number between 0 and 39. This IE is fixed in different realizations as MD. If the IE is not present, “Sequence signatures” takes a default value.
The default value is a function of the position of the resource of E-DCH common within the list, a function of the value of “Sequence Signatures” from a case of resource E-DCH common prior or a function of the position of the resource of E-DCH common and the value of “Sequence Signatures” from a case of resource E-DCH common prior. The first resource of E-DCH common defined would occupy the position 0 (or 1). The second resource of E-DCH common defined would occupy position 1 (or 2). Similar reasoning would apply with the other resources defined. A realization

concrete can be, for example, if the Sequence “Signatures” for the first case of the appeal of E-DCH common take a default value and the rest of the resources of E-DCH common to take a value function of the last case in the IE.
For example, we present below a simple formula to set default values for each resource E-DCH common as defined in that the IE is not present.
Sequence Signatures = (position of list of resources of E-DCH common + offset) mod 40 where “offset” is the value of the last occurrence of the IE “Sequence Signatures”. If “Sequence Signatures” was not present in the first case, the “offset” is equal to zero.
“position of list of resources of E-DCH common” indicates the number of resource Configuration Information of E-DCH common by order of appearance. The value of the “position list of resources E-DCH common” is zero (or one) for the first case. If the IE is present, the value pointed to overwrite the default value.

Code number randomisation is a value to this MP. This IE take a number of bits that are relatively large for each resource E-DCH common. This IE is changed in some realizations conditional on value (CV) in its place, avoiding to include such a number of bits large resource of E-DCH common set up.
Conditional on a value would mean that this IE is present mandatory for the first occurrence. Otherwise, this IE is optional. In addition, if this IE is not present, the value of the IE is a function of the latter case. For example, it may be a function of the position of the resource of E-DCH common within the list of resources of E-DCH common a function of the value Information “of the code of DPCH uplink for E-DCH common” a case of the appeal of E-DCH common prior or a function of the position of the resource of E-DCH common and the value of Information “code of DPCH uplink for E-DCH common” a case of the appeal of E-DCH common prior. The following formula illustrates how you can set the values by default if the IE is not included:
Code number of randomization = position of list of resources of E-DCH common + offset, where "offset" is the value of the last occurrence of the IE “code Number randomization”. If “scrolling” was not present at the first event or occurrence, “offset” is equal to zero.
"position of list of resources of E-DCH common" indicates the number of resource Configuration Information of E-DCH common by order of appearance. The value of the “position list of resources E-DCH common” is zero (or 1) for the first case. If the IE is present, the value pointed to overwrite the default value.
In this manner, in some embodiments the second available resource is defined by a value in an information element of a code of randomization is a Control Channel Dedicated Physical uplink. The value can be a function of the position of the second available resource within the ordered list of resources of E-DCH common a function of a value in an information element of a code of randomization is a Control Channel Dedicated Physical uplink of a first resource is available prior to or a function of the position of the second available resource and a value-of-Information “code of DPCH uplink for E-DCH common” in the information element of a code of randomization is a Control Channel Dedicated Physical uplink of the first resource available to them prior.
>>Information of the E-DPDCH
E-TFCI of minimum set of E-DCH
This IE is mandatory default. If you omit this IE, means that there is a set E-TFCI to a minimum.
In the case of E-DCH in cell_fach states and Idle Mode, the UE will send always your message, especially messages on CCCH. Otherwise, the EU will be blocked and, potentially, the EU will drop. It seems obvious that for E-DCH in cell_fach states and Idle Mode, the E-TFCI of minimum set of E-DCH is always included and must be necessary to a number above zero (the Index of E-TFCI 0 only would allow the EU to send the Scheduling Information).
Therefore, the semantic description can be modified so that for cell_fach states, and Idle Mode (or for Uplink Enhanced in cell_fach states and Idle Mode), if the IE is not included, the E-TFCI of minimum set of E-DCH is set to a defined value. The only restriction for this value is that the value belongs to the set of values defined in the table of E-TFCI. The particular table to be used is indicated in the IE “table of contents table of E-TFCI” also included in the IE “Information of E-DPDCH”. As mentioned before, the value of E-TFCI of zero only allows the UE to transmit the Scheduling Information. Therefore, the value of E-TFCI reasonable minimum so that the UE can transmit control data of higher layers or user is the value of E-TFCI 1.
If the IE is present, the values listed overwrite the default value.
Applying the encoding suggested before, the structure of the IE “Parameters of control preamble of PRACH for Uplink Enhanced” and other IE involved would result in shown below. The EI affected are underlined and IE are not affected are defined in reference to the Technical Specification (TS) 25.331 section 10 version 10.0.0 of the 3GPP:

In one embodiment, the circuit RX 603 of the mobile terminal 10 is configured to receive system information that indicates a first available resource of a channel CB. The processing circuit 604 of the mobile terminal 10 may be configured to derive then the information for a second available resource of the channel CB in the basis, for example as a function of the first resource available. This may involve, for example, to derive information for the second available resource according to a default rule that defines the second resource as a function of the first resource, for example, as a function of the position of the first resource within an ordered list describing the resources. The processing circuit 604 may optionally in some embodiments randomly select a preamble of the access request corresponding to a second available resource of the second channel of the uplink based on containment. The circuit TX 602 can then transmit the preamble selected, and the circuit RX 603 can receive an acknowledgement of receipt positive. Whether or not in response to the preamble selected transmitted, the processing circuit 604 may derive system information for a second available resource of the second channel of the uplink based on the containment on the basis of, for example, as a function of the first resource available. Finally, the circuit TX 602 can be concluded in different realizations with the data transmission of up-link in the second channel of the uplink based on containment using the second available resource.
In this way, the embodiments of the mobile terminal 10 for requesting access to a wireless communication system is shown in Fig. 6. The mobile terminal 10 comprises the circuit receiver 603 is configured to receive informationon system spread which indicates directly the first preamble access request for the first channel based on contention, and they indicate indirectly a few seconds preambles to request access to the second channel based on contention on the basis of the first preamble access request indicated directly. The mobile terminal 10 further comprises the processing circuit 604 configured to derive the second preamble access request from the first preamble access request and configured to request access using the second preamble access request or the first preamble access request to access the wireless communication system. The processing circuit 604 may be configured in addition in some embodiments to select randomly one of the preambles of request for access and transmitting preamble of access request is selected randomly.
The first channel based on contention may correspond to a channel random access, RACH. The second channel based on contention may correspond to a Dedicated Channel Enhanced, E-DCH, common. The processing circuit 604 may be configured in some embodiments to derive the second preamble access-request as a function of the first preamble access request. The system information broadcast is received may be contained in a Block of System Information type 5, SIB5. The first preamble access request may correspond to a preamble Channel Random Access Physical, PRACH, characterized by a sequence of signatures, a code of randomization, and a sub channel. In some embodiments, the first preamble access request can be indicated in an information element designated as Channel information, Random Access-Physical, PRACH, comprised in a list of system information PRACH transported in a Block of System Information type 5, SIB5. In some embodiments, the first preamble access request for the first channel based on containment can be indicated as signatures available in the information element information of the PRACH and the second preamble access request to the second channel based on containment can be indicated indirectly as a function of the first preamble access request in an information element designated as the signatures available in an item of information designated control parameters preamble of PRACH for uplink enhanced. In some embodiments a number of code randomization of the preamble of the second preamble access request may be a code for randomization of the preamble of the first preamble access request. In some embodiments a number of code randomization of the preamble of the second preamble access request may be a function of the code of randomization of the preamble of the first preamble access request. In some embodiments a number of sub available channel of the second preamble access-request can be adjusted to be equal, the inverse or a function ‘not’ of a number of sub available channel indicated in the information element designated information of the PRACH.
In some embodiments the system information broadcast is received may also indicate the second available resource of the second channel based on contention regarding the first available resource of the second channel based on contention. In some embodiments the second available resource may be indicated in an ordered list of resources as a function of a position of the first available resource in the ordered list. The ordered list may define a resource of Dedicated Channel Enhanced, E-DCH, common, each Resource E-DCH is defined by an item of information Soffset, an item of information of code number of Control Channel Dedicated Physical Fractional, F-DPCH and an item of information of Channel information of the Indicator of Acknowledgement of Receipt of Application of Auto-Repeat Hybrid of E-DCH, E-HICH for E-DCH common. The position of the second available resource in the ordered list can be defined by a default value in the item of information Soffset. The default value can be a function of the position of the second available resource within the ordered list, a function of a “Soffset” from a first resource is available prior to or a function of the position of the second available resource and an offset value. The offset value may be a value Soffset of the first available resource. In some embodiments the information element number of a code of F-DPCH can be the same for a maximum of ten resources of E-DCH common. In some embodiments the information element information E-HICH for E-DCH common can be defined by a
code channel and a sequence of signatures, and a default value of the sequence of signatures is a function of the position of the second available resource within the ordered list, a function of a value of “Sequence Signatures” of a first resource is available prior to or a function of the position of the second available resource and the value of “Sequence Signatures” of a first resource is available prior. In some embodiments a code 5-pipe of the second available resource may be equal to a code pipeline of the first available resource. In some embodiments the second available resource may be defined by a value in an information element of a code of randomization is a Control Channel Dedicated Physical uplink. The value can be a function of the position of the second available resource within the ordered list of resources of E-DCH common, a function of a value in an information element of a code of randomisation of a Channel
10 Control Dedicated Physical uplink of a first resource is available prior to or a function of the position of the second available resource and a value-of-information “code of DPCH uplink for E-DCH common” in the information element of a code of randomization is a Control Channel Dedicated Physical uplink of the first resource available to them prior.
