DESCRIPTION
Mobile terminal, base station and methods within it
Technical field
The embodiments herein relate to a mobile terminal, a base station, and methods within it. In particular, the embodiments herein relate to requesting access to a wireless communication system.
Background
A number of different technologies are used in today's wireless communication systems, such as Long Term Evolution (LTE), LTE-Advanced, Wideband Code Division Multiple Access (WCDMA), Global System for Mobile communications / Enhanced Data Rate for Evolution of GSM (GSM / EDGE), Worldwide Interoperability 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 radio coverage over at least one respective geographic area that forms a cell. The cell definition can also incorporate frequency bands used for transmissions, which means that two different cells can cover the same geographic area but using different frequency bands. The mobile terminals are served in the cells by the respective base station and communicate with the respective base station. Mobile terminals transmit data over an air or radio interface to base stations in uplink (UL) transmissions and base stations transmit data over an air or radio interface to mobile terminals in downlink (DL) transmissions.
Third Generation Cooperative Project (3GPP) Standards Publication 6 introduced Enhanced Uplink (E-UL), also known as High Speed Uplink Packet Access (HSUPA). Compared to previous publications E-UL improved the performance of uplink communications - those from a mobile terminal, ie User Equipment, to a base station using higher data rates, reduced latency and improved system capacity. These improvements were implemented through a new transport channel called the Enhanced Dedicated Channel (E-DCH). In Publication 6 and continuing in Publication 7, however, a mobile terminal can only use the E-DCH in limited circumstances.
Specifically, at the Radio Resource Control (RRC) level, a mobile terminal can be in two basic modes of operation, called IDLE mode and ON mode. In the IDLE mode, the mobile terminal requests an RRC connection before sending any uplink data or responding to a page. In CONNECTED mode, on the contrary, the mobile terminal has an RRC connection and can be in one of several service states: Universal Mobile Telecommunications System (UMTS) Radio Access Search Channel state (URA_PCH), a state of Cell Search Channel (CELL_PCH)), a Cell Direct Access Channel status (CELL_FACH) and Cell Dedicated Channel status (CeLL_DCH). The URA_PCH and CELL_PCH states are search states in which the mobile terminal rests and only occasionally wakes up to check a search. To send uplink data, the mobile terminal moves to the CELL_FACH or CELL_DCH state. When moved to the CELL_FACH state in Publications 6 and 7, the mobile terminal can send a relatively small amount of uplink data over a contention-based transport channel called the Random Access Channel (RACH), but not over 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, 3GPP Standards Publication 8 allocates a portion of the E-DCH resources as common resources, also called common E-DCH resources, which can be used on a contention by mobile terminals in the CELL_FACH state. Consequently, mobile terminals in the CELL_FACH state with a relatively large amount of uplink data can send that data on the E-DCH using the common E-DCH resources rather than having to do multiple accesses on the RACH or switch to the CELL_DCH status.
This however comes at the cost of an increase in uplink control signaling. Indeed, the base station now broadcasts system information to mobile terminals informing them about which access request preambles can be used to request E-DCH access and which E-DCH resources are available as E-DCH resources. Common DCH. Among other disadvantages, this increased DL control signaling can delay the base station signaling of more crucial system information.
For example, a base station often broadcasts system information in a series of so-called System Information Blocks (SIBs). Different types of system information are broadcast in different types of SIBs, one after another in a time division way. This process is repeated to continuously provide system information to the mobile terminals in an as needed manner. Accordingly, any spread given large SIB delays of the entire series of SIBs are repeated, which in turn increases the time between which any given SIBs, ie, the SIB repetition factor. If the repetition factor of SIB is
ES 2 534 612 T3 excessively large for a SIB with crucial system information, there may be long periods of time when a mobile terminal cannot search, send uplink data, perform a cell update or return to a circuit switched network, also called CS return. These types of delays can be caused by the increased DL control signaling associated with Publication 8 of the 3GPP standards, causing reduced performance of the wireless communication system.
WO2007052971 shows a prior art system that transmits resource information from a contention-based channel to a UE.
WO2009057032 shows a communication method between a primary station and a secondary station that comprises a signaling step of two random access channels of different types based on a difference in resources for the two random access channels.
Compendium
An object of the embodiments herein is to improve the performance of the wireless communication system.
According to one aspect of the embodiments herein, the object is achieved by a method in a mobile terminal for requesting access to a wireless communication system. The mobile terminal receives broadcast system information indicating a first available resource of a contention-based channel. The mobile terminal derives a second available resource from the contention-based channel based on the first available resource from the contention-based channel. The mobile terminal further transmits an access request preamble correlated to the second resource available to access the wireless communication system.
According to another aspect of the embodiments herein, the object is achieved by a method at the base station for managing access to a wireless communication network. The base station encodes the system information indicating the second available resource of the contention-based channel relative to the first available resource of the contention-based channel. The base station broadcasts the encrypted system information.
According to yet another aspect of the embodiments herein, the object is accomplished by a mobile terminal to request access to a wireless communication system. The mobile terminal comprises a receiver circuit configured to receive broadcast system information indicating a first available resource of a contention-based channel. The mobile terminal further comprises a processing circuit configured to derive a second available resource from the contention-based channel based on the first available resource from the contention-based channel, and transmit an access request preamble correlated to the second available resource.
According to yet another aspect of the embodiments herein, the object is achieved by a base station for managing access to a wireless communication network. The base station comprises a processing circuit configured to encode system information indicating a second available resource of a contention-based channel relative to a first available resource of the contention-based channel. Additionally, the base station comprises a transmitter circuit configured to broadcast the system information.
By indicating the available resources of the contention-based channel relative to other available resources of this channel, the amount of data reported in the system information is reduced. In this way, the delay for transmitting system information is reduced and the performance of the wireless communication system is improved.

Detailed description
ES 2 534 612 T3
Fig. 1 is a schematic overview showing a wireless communication system, also known as a radio communication network. A number of different technologies are used in today's wireless communication systems, 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. Base station 12 provides an uplink communication channel 16 for receiving uplink data from individual mobile terminals 10, 10-1, 10-2 10-N in a group 20 of N mobile terminals, also conveniently known as "Users" or "user computers". Base station 12 further provides a downlink communication channel 22 to send transmissions to mobile terminals 10-10-N in group 20, including control signaling.
It should be understood by those skilled in the art that "mobile terminal" is a non-limiting term meaning any user equipment, wireless terminal, device or node for example a Personal Digital Assistant (PDA), laptop, mobile, sensor, relay. , mobile tablets or even a small base station communicating within a cell served by base station 12.
The base station 12 may also be known as for example a NodeB, an evolved NodeB (eNB, eNodeB), a radio base station, a transceiver base station, Access Point Base Station, base station router, a base station controller. , a radio network controller or any other network unit capable of communicating with mobile terminals 10-10-N within the cell served by base station 12 depending for example on the radio access technology and terminology used.
The base station 12 can support two Containment Based (CB) channels of the uplink communication channel 16, a legacy CB channel, for example, offering low data rates such as a RACH and a non-legacy CB channel, for example. , which offers high data rates such as an E-DCH. Some 10-1-10-N mobile terminals, known as legacy mobile terminals, only support the legacy CB channel, while others support both CB channels. If the mobile terminal 10 supports both channels, the mobile terminal 10 can preferentially select the non-legacy CB channel to send uplink data. In order to manage access to both CB channels, base station 12 broadcasts system information for both CB channels on a control channel of downlink communications channel 22. Containment-based channel means herein a channel that can use many mobile terminals without prior coordination. Thus, for a contention-based channel, base station 12 broadcasts access request preambles that mobile terminal 10 randomly selects. In a non-contention-based channel, base station 12 first maps an access request preamble to mobile terminal 10 and then transmits the mapped access request preamble to mobile terminal 10 for mobile terminal 10 for use. Base station 12 broadcasts system information indicating which CB channel resources are available. As an advantage, the base station 12 intelligently broadcasts system information for the CB channels, in order to limit the amount of downlink control signaling. According to the embodiments herein, instead of broadcasting system information to mobile terminals 10-10-N that independently indicates available resources, the base station 12 encodes system information that indicates the available resources of one CB channel relative to others. available resources of that channel, for example, relative to a position in which other available resources are indicated in the system information. In some embodiments, for example, available resources are indicated in an ordered list and base station 12 indicates available resources as a function of its position in the list relative to other resources. Base station 12 broadcasts this system information to mobile terminals 10-10-N.
In the same way, mobile terminal 10 is configured to receive system information indicating a first available resource of a CB channel. Mobile terminal 10 is configured to then derive information for a second available resource from the CB channel based on, or as a function of, the first available resource. This may involve, for example, deriving information for the second available resource according to a predetermined 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 that describes the resources. In various embodiments, the second available CB channel resource is mapped to an access request preamble randomly selected by the mobile terminal. In such embodiments, the mobile terminal 10 is configured to derive information to derive information for the second available resource in response to receiving a positive acknowledgment corresponding to the selected preamble and then transmitting uplink data on the CB channel using the second resource. available. The embodiments described herein can advantageously reduce the required signaling in System Information Blocks (SIB), especially a System Information Block type 5 (SIB5) such as the information of the preambles indicated therein, to spread the total amount of common E-DCH resources about 70% compared to current signaling.
Fig. 2 is a combined schematic flow diagram and signaling scheme depicting some embodiments herein.
Step 201. The base station 12 encodes the system information to be broadcast to the mobile terminals within an area covered by the base station 12. The system information indicates the available resources of the contention-based channel, for example the second channel based in containment. The contention-based channel can be
ES 2 534 612 T3 represent by a Random Access Channel (RACH) or by an Enhanced Dedicated Channel (E-DCH). The encoded system information indicates the available resources of the contention-based uplink channel relative to other available resources of that contention-based channel.
Step 202. Base station 12 broadcasts system information to one or more mobile terminals 10-10-N.
The base station 12 may further broadcast over the control channel system information indicating which first access request preambles and second access request preambles can be used to request access using the respective of the CB channels. Each access request preamble can be mapped to a particular resource on a CB channel. In this regard, the CB channels share the access request preamble "space".
As an advantage, the base station 12 intelligently broadcasts system information for the CB channels, in order to limit the amount of downlink control signaling. Instead of broadcasting system information to mobile terminals 10-10-N that independently indicates access request preambles for the respective of the CB channels, base station 12 can broadcast system information that indirectly indicates access request preambles. for one channel, for example, the non-legacy CB channel, based on, for example as a function of the access request preambles for the other channel, for example, the legacy CB channel. Indirectly herein means that the second access request preambles are derivable from the first access request preambles, for example as a function of the indicated first access request preambles. In the same way, the mobile terminal 10 can receive system information that directly indicates the access request preambles for one channel, for example, the legacy CB channel, and can derive the access request preambles for the other channel, for example. , the non-legacy CB channel, as a function of the directly indicated access request preambles. The mobile terminal 10 can then randomly select one of the derived access request preambles and transmit the selected access request preamble to the base station 12, in order to request access to the associated CB channel, i.e. the non-legacy channel. or the legacy channel.
Step 203. The mobile terminal 10 which has received the broadcast system information indicating a first available resource, derives a second available resource from the system information as well as the access request preambles of the CB channels. This may be the case when the first available resource generates an unrecognized access request.
Step 204. At some point after receiving this system information, the mobile terminal 10 requests access to a supported or preferred one of the CB channels, the first or the second contention-based channel, for example, by randomly selecting one of the first or second access request preambles associated with that channel and transmitting the selected preamble to base station 12 with the second available resource.
Step 205. The base station 12 that has received the transmitted access request preamble performs contention management for the associated CB channel.
Step 206. Base station 12 transmits or signals on downlink communication channel 22 whether or not the base station recognizes or denies the mobile terminal's request for access to that channel using the second available resource.
Step 207. If mobile terminal 10 receives a positive acknowledgment, mobile terminal 10 proceeds by sending uplink data on any available resource, eg, the second resource as exemplified, of the associated CB channel that is correlated to the preamble. access request selected and recognized.
The embodiments described herein advantageously reduce the signaling required in SIB5 to spread the total amount of common E-DCH resources by about 70% compared to current signaling. In particular, after Publ-8, SIB5 can be substantially enlarged due to common E-DCH configurations. A total of 32 common E-DCH resources can be configured in one cell. If all these resources are included in SIB5, the size of SIB5 would be increased by 8 segments, where a segment consists of a header and a data field, for example, the data field carries the encoded system information elements. This would mean that SIB5 can take more than 12 segments and in turn it would mean that a Master Information Block of up to 16 segments, SIB11 of up to 16 segments and SIB5 would take more than 50% of the 64 available segments in a programming window frame of 1,280 seconds. As a consequence, SIB5 would not be able to be broadcast in less than 640 ms, which means that the repetition factor may need to be increased. However, according to the above embodiments, the number of segments to broadcast SIB5 can be reduced to less than 3 segments. This means that the repetition factor of SIB5 can be reduced. Therefore, the delay to transmit Radio Bearer (RB) reconfiguration of URA / CELL updates when applied or the delay introduced in the CS return mechanism will be minimized. In more detail, the SIBs are read by the mobile terminal 10 in different stages. For example, when the mobile terminal 10 is powered on or when the mobile terminal 10 moves from the CELL_DCH state to the CELL_FACH state, the mobile terminal 10 needs to acquire the SIBs again. Similarly, when mobile terminal 10 moves to another cell, the new SIBs have to be read.
ES 2 534 612 T3
The cell update will be the most impacted procedure. The cell update is done when moving from a CELL_DCH state to a CELL_FACH state if the IDs are not included or the mobile terminal 10 selects a different cell than indicated in the RB reconfiguration. The cell update is also performed when the mobile terminal 10 changes the cell. For E-DCH on mobile terminals in the CELL_FACH state and the CELL_DCH state, Cell Update is also required after a Radio Link (RL) failure. There are other cases in which a cell update is required.
Additionally, in Publication-10 of the 3GPP standards, also known as 4<sup>to</sup> Generation, CS return from LTE was introduced. This feature may require the mobile terminal 10 to read the SIBs before starting the procedure.
Those skilled in the art will appreciate that while the examples have been described in the context of the 3GPP standards, these teachings are applicable to a wide range of system types, communication pipeline schemes, etc.
FIG. 3 is a schematic flow diagram depicting a method at base station 12 for managing access to the wireless communication network in accordance with embodiments herein.
Step 301. Base station 12 encodes system information indicating the second available resource of the contention-based channel relative to the first available resource of the contention-based channel. The contention-based channel may, in some embodiments, correspond to a random access channel, RACH, or an Enhanced Dedicated Channel, E-DCH. The system information can be comprised in a System Information Block type 5, SIB5. Additionally, the second available resource 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 is, in some embodiments, defining common Enhanced Dedicated Channel, E-DCH, resources. Each E-DCH Resource is defined by a Soffset information element, a Fractional Dedicated Physical Control Channel code number information element, F-DPCH, and an Acknowledgment Indicator Channel information information element. E-DCH Hybrid Automatic Repeat Request, E-HICH, for common E-DCH. The position of the second available resource in the ordered list is defined, in some embodiments, by a default value in the Soffset information element. The default value can be, for example, a function of the position of the second available resource within the ordered list, a function of a “Soffset” value of a previous first available resource, or a function of the position of the second available resource and an offset value. The offset value in these embodiments is a Soffset value of the first available resource. The F-DPCH code number information element is, in some embodiments, the same for up to ten common E-DCH resources. The E-HICH information for a common E-DCH information element can be defined by a channelization code and a signature sequence. A default value of the signature sequence can be, for example, a function of the position of the second available resource within the ordered list, a function of a "Signature Sequence" value of a previous first available resource, or a function of the position of the second available resource and the value of "Signature Sequence" of a previous first available resource. A channel code of the second available resource is, in some embodiments, equal to a channel code of the first available resource.
The second available resource can be defined by a value in an information element of a scrambling code of an uplink Dedicated Physical Control Channel. The value can be, for example, a function of the position of the second available resource within the ordered list of common E-DCH resources, a function of a value in an information element of a scrambling code of a Control Channel Dedicated uplink physical from a previous first available resource, or a function of the position of the second available resource and a value of "Uplink DPCH code information for Common E-DCH" in the information element of a scrambling code of an uplink Dedicated Physical Control Channel of the first prior available resource.
Step 302. The base station 12 broadcasts the encrypted system information. Thus, base station 12 manages access by broadcasting system information indicating the available resource to be used to access the wireless communication system.
The embodiments herein advantageously reduce downlink control signaling associated with contention-based uplink access for a wireless communication system.
Embodiments herein further reduce downlink control signaling in that instead of broadcasting system information to mobile terminals independently indicating access request preambles for each of the two contention-based uplink channels (CB), The base station 12 according to some embodiments may broadcast system information that indirectly indicates the access request preambles for a channel based on, or as a function of the preambles for the other channel. In the same way, the mobile terminal 10 receives system information that directly indicates the access request preambles for one CB channel and derives the access request preambles for the other CB channel as a function of the directly indicated preambles.
ES 2 534 612 T3
As a specific example in the context of 3GPP specifications, base station 12 may support CB channels that correspond to the common Random Access Channel (RACH) and the common Enhanced Dedicated Channel (E-DCH). Accordingly, the base station 12 broadcasts system information for these channels in a System Information Block (SIB), that is, SIB Type 5. The system information for the RACH is broadcast in SIB5 5 using the Information Element (IE) "PRACH System Information List", while the system information for the common E-DCH is broadcast in SIB5 using the IE " Common E-DCH System Information ”. An access request preamble as used above corresponds to a PRACH preamble, which is characterized by a signature sequence, a scrambling code and a sub channel.
In more detail, the embodiments herein reduce the number of segments used in SIB5 to broadcast the IE "Common E-DCH System Information" defining the common E-DCH resource parameters.
For this purpose, a new encoding is proposed for IE included in the IE "Common EDCH System Information" within SIB5. The IE "Common E-DCH System Information" is an optional IE included in SIB5.

MP stands for Mandatory Present and OP stands for Optional. An IE that is Mandatory Present always needs to be included and has a value while the value of an optional IE may or may not be present. MD stands for Required By Default. When an IE is set to Mandatory by Default, a value is always needed for that IE and a particular default value is mentioned.
The embodiments herein propose modifications to some of those EIs, as detailed below.
>> List of Common E-DCH Resource Configuration information
This IE is a list comprising all common E-DCH resources. A maximum of 32 common E-DCH resources can be included in this list. For each defined common E-DCH resource, the following IE's are defined:
>>> Soffset
This IE is an IE MP whose value ranges from 0 to 9. This value indicates the specific range within the F-DPCH in which power control commands are included for a specific F-DPCH code.
Instead of being MP, this IE is set as MD in various embodiments. If IE is not present, "Soffset" takes a default value. The default value is a function of the position of the common E-DCH resource within the list, a function of the “Soffset” value of a previous common E-DCH resource instance, or a function of the position of the E-DCH resource. -Common DCH and the “Soffset” value from a previous common E-DCH resource instance. The first common EDCH resource defined would occupy a position 0 (or 1). The second defined common E-DCH resource would occupy a position 1 (or 2). Similar reasoning would apply with the other defined resources.
A concrete embodiment would be, for example, if the value "Soffset" for the first case of the common E-DCH resource takes a default value and the rest of the common E-DCH resources take a value related to the last case.
For example, a simple formula for setting default values for each defined common EDCH resource is presented below.
Soffset = (common E-DCH resource list position + offset) mod 10 where “offset” is the value of the last case of the “Soffset” IE. If the IE "Soffset" was not present in the first case, "offset" is equal to zero.
"Common E-DCH Resource List Position" indicates the number of Common E-DCH Resource Configuration information in order of appearance. The value of "common E-DCH resource list position" can be zero (or one) for the first case.
If IE is present, the designated value overwrites the default value.
>>> F-DPCH code number
This IE indicates the code to be used for the F-DPCH.
Instead of being MP, this IE is optional, conditional on a value.
If the encoding presented for the Soffset is applied, potentially only three instances of the F-DPCh code number are needed, once for every 10 common E-DCH resources. Therefore, in the best configuration, only three cases would need to be present.
Therefore, this IE is in various embodiments set as conditional to a value (CV) so that this IE is obligatorily present for the first occurrence. Alternatively, it should be present compulsorily
ES 2 534 612 T3 for the first occurrence or if the default value is equal to zero. Otherwise this IE is optional. Also, if this IE is not present, the value is equal to the last occurrence of this IE.
If IE is present, the designated value overwrites the default value.
>>>> E-HICH information
E-HICH information contains two additional IE's. Changes to this IE would imply impacts on Release 6 and Release 7 of the 3GPP standards. In order to avoid impacts in earlier versions, a new IE can be used instead: “E-HICH information for common E-DCH”. Only two IE would be needed as this feature only applies to FDD.
>>> E-HICH information for common E-DCH
Pipeline code
This IE can be set as an IE conditioned to a 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.
If IE is present, the designated value overwrites the default value.
Signature sequence
The value of this IE is a number between 0 and 39. This IE is set as MD in various embodiments. If IE is not present, "Signature Sequence" takes a default value.
The default value is a function of the position of the common E-DCH resource within the list, a function of the “Signature Sequence” value of a previous common E-DCH resource instance, or a function of the position of the resource. common E-DCH and the “Signature Sequence” value from a previous common E-DCH resource instance. The first defined common E-DCH resource would occupy position 0 (or 1). The second defined common E-DCH resource would occupy position 1 (or 2). Similar reasoning would apply with the other defined resources. A concrete implementation can be, for example, if the value "Signature Sequence" for the first case of the common E-DCH resource takes a default value and the rest of the common E-DCH resources take a value based on the last IE case.
For example, a simple formula to set default values for each common EDCH resource where IE is not present is presented below.
Signature Sequence = (common E-DCH resource list position + offset) mod 40 where “offset” is the value of the last occurrence of the “Signature Sequence” IE. If "Signature Sequence" was not present in the first case, "offset" is equal to zero.
"Common E-DCH Resource List Position" indicates the number of Common E-DCH Resource Configuration Information in order of appearance. The value of the "common E-DCH resource list position" is zero (or one) for the first case.
If IE is present, the designated value overwrites the default value.
>>> Uplink DPCH code information for common E-HCIH
Scrambling code number is a present value MP. This IE takes a relatively large number of bits for each common E-DCH resource. This IE is changed in some embodiments to condition a value (CV) instead, avoiding including such a large number of bits per configured common E-DCH resource.
Conditioned to a value would mean that this IE is necessarily present for the first occurrence. Otherwise this IE is optional. Also, 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 common E-DCH resource within the list of common E-DCH resources, a function of the "Uplink DPCH code information for common E-DCH" value of a previous common E-DCH resource case or a function of the position of the common E-DCH resource and the value of "Uplink DPCH code information for common E-DCH" of an E-DCH resource case previous common. The following formula illustrates how the default values can be set if IE is not included:
Scrambling code number = common E-DCH resource list position + offset where offset is the value of the last occurrence of the IE "Scrambling Code Number". If "displacement" was not present in the first case or occurrence, "displacement" is equal to zero.
ES 2 534 612 T3 common E-DCH resource list position indicates number of common E-DCH resource Configuration Information in order of appearance. The value of "common E-DCH resource list position" is zero (or 1) for the first case.
If IE is present, the designated value overwrites the default value.
>> E-DPDCH information
E-DCH Minimum Set E-TFCI
This IE is required by default. If this IE is omitted, it means that there is no minimum E-TFCI set.
In the case of E-DCH in CELL_FACH and Idle Mode, the UE will always send its message, especially CCCH messages. Otherwise the UE will crash and potentially the UE will be dropped. It seems obvious that for E-DCH in CELL_FACH and Idle Mode, the E-DCH minimum set E-TFCI will always be included and it will be necessary that it must be a number above zero (E-TFCI Index 0 would only allow the UE send the Programming Information).
Therefore, the semantic description can be modified so that for CELL_FACH and Idle Mode (or for Enhanced Uplink in CELL_FACH and Idle Mode), if the IE is not included, the E-DCH minimum set E-TFCI is set to a defined value. The only restriction on this value is that the value belongs to the set of values defined in the E-TFCI table. The specific table to be used is indicated in the IE "E-TFCI table index" also included in the IE "E-DPDCH Information". As mentioned before, the value of E-TFCI zero only allows the UE to transmit the Programming Information. Therefore, the reasonable minimum E-TFCI value so that the UE can transmit user or higher layer control data is the ETFCI 1 value.
If IE is present, the designated values override the default value.
>> PRACH Preamble Control Parameters for Enhanced Uplink
This IE is characterized by available signatures, preamble scrambling code numbers, and Available Sub Channel Numbers.
Available Signatures
This is a bit string IE and each bit indicates whether or not a signature is used. The signatures configured for RACH and included in the IE "Available Signatures" present in the IE "PRACH Information (for RACH)". These signatures cannot be used for Enhanced Uplink in CELL_FACH and Idle Mode. The IE "PRACH Information (for RACH)" is included in the IE "List of PRACH System Information" which is carried in SIB5. "List of PRACH System Information", "PRACH Information (for RACH)" and "Available Signatures" are IE mandatory. Therefore, they will always be included in SIB5.
The IE "Available Signatures" contained in the IE "PRACH Preamble Control Parameters for Enhanced Uplink" is also a mandatory present value; 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 "Available Signatures" present in the IE "PRACH Information (for RACH)".
As an example, the default value in various embodiments is a "REVERSE" or "NO" function operation of the bit string values included in "Available Signatures" present in the IE "PRACH Information (for RACH)".
An illustrative example is presented to clarify the concept. If the value of the IE "Available Signatures" included in the IE "PRACH Information (for RACH)" is: 1111111100000000, then the default value of the IE "Available Signatures" contained in the IE "Common E-DCH System Information ”Would be the inverse bit operation of (1111111100000000) which is equal to 0000000011111111. Therefore, the IE "available signatures" is set to mandatory by default (MD) and the semantics of the description would say that the default value is the reverse bit string indicated in the IE "Signatures Available" in the IE "Information of PRACH (for RACH) ”. In other words, the signatures available for Enhanced Uplink in CELL_FACH are those signatures that are not used for RACH, unless IE is present.
By doing so, the base station 12 suppresses including this IE in the IE "PRACH Preamble Control Parameters for Enhanced Uplink" and thereby reduces the downlink control signaling. A mobile terminal 18 that does not receive such an IE however sets the IE to a default value described above. If IE is present, the designated values override the default value.
Preamble scrambling code number
This IE is also included in the IE "PRACH Information (for RACH)". The embodiments herein teach that the scrambling code for the common E-DCH is the same as that of the RACh, at least for
ES 2 534 612 T3 defective. If different, the new Preamble Scrambling Code Number in various embodiments is a function of the Preamble Scrambling Code Number present in the "PRACH Information (for RACH)" IE. Therefore, this IE in some embodiments is MD and by default equal to the IE "Preamble scrambling code number" indicated in the IE "PRACh Information (for RACH)" and is otherwise a function of the IE "Number Preamble Scrambling Code "indicated in the IE" PRACH Information (for RACH) ".
As in the previous case, the base station 12 refrains from including this IE in the IE "PRACH Preamble Control Parameters for Enhanced Uplink" and thereby reduces the downlink control signaling. A mobile terminal 18 that does not receive such an IE however sets the IE to a default value described above. If IE is present, the designated values override the default value.
Sub Channel Number Available
This IE is a bit string. Each bit indicates the availability of 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 corresponding sub channel is available and the value 0 indicates that it is not available.
This IE is also included in the IE "PRACH Information (for RACH)". This IE in some embodiments is also set to MD. The mandatory default value is a function of the IE "PRACH Information (for RACH)".
For example, this IE can be set equal to the IE "Number of Sub Channel Available" indicated in the IE "PRACh Information (for RACH)". In another approach, the default value may be the REVERSE (or NO) function of the IE "Sub Channel Number Available" indicated in the IE "PRACH Information (for RACH)".
As in the previous case, the base station 12 refrains from including this IE in the IE "PRACH Preamble Control Parameters for Enhanced Uplink" and thereby reduces the downlink control signaling. A mobile terminal 18 that does not receive such an IE however sets the IE to a default value described above. If IE is present, the designated values override the default value.
Applying the coding suggested above, the structure of the IE "PRACH Preamble Control Parameters for Enhanced Uplink" and other implicated IEs would be translated as shown below, affected IEs are indicated with underlined text and unaffected IEs are defined in reference to the Technical Specification (TS) 25.331 section 10 version 10.0.0 of the 3GPP:

If the IE "Common E-DCH System Information" is not present, this IE is mandatory for the first occurrence. Otherwise this IE is optional.
NOTE1: The default value is defined by: Signature Sequence = (common E-DCH resource list position + offset) mod 40 where offset is the value of the last appearance of the Signature Sequence IE. If "Signature Sequence" was not present in the first case, "offset" is equal to zero.
Common E-DCH Resource List position indicates the number of Common E-DCH Resource Configuration Information in order of appearance. The value of the common E-DCH resource list position "is zero for the first case.
IE "E-DPCH Information" and "Uplink DPCH Code Information for Common E-DCH" cannot be changed compared to the first solution.
The encoding enhancement of each IE present in "Common E-DCH System Information" is independent of other IEs.
FIG. 4 is a block diagram depicting base station 12 according to embodiments herein. To support the above downlink control signaling, base station 12 in some embodiments includes one or more transmit / receive antennas 402, along with associated transmitter (TX) circuit 404 and receiver (RX) circuit 401, respectively, and further includes one or more processing circuits 403. The processing circuit 403 of the base station 12 encodes system information indicating the available resources of a CB channel relative to other available resources of that CB channel, for example, relative to the position in which other available resources are indicated in the system information, rather than indicating each resource independently. In some embodiments, for example, available resources are indicated in an ordered list and processing circuit 403 encodes system information to indicate available resources as a function of their position in the list relative to other resources. This may entail, for example, suppressing the encoding that would directly indicate certain access request preambles. The TX circuit 404 is then configured to broadcast the encoded system information to the mobile terminals 10-10-N, through the transmit antennas 402.
In some embodiments, the processing circuit 403 is further configured to encode system information that directly indicates access request preambles for one of the CB channels and indirectly indicates access request preambles for the other CB based on, or as a function of, the directly stated preambles. The TX circuit 404 then broadcasts this system information in the same way as previously described. This may entail, for example, suppressing the encoding that would directly indicate certain access request preambles.
Thus, base station 12 for managing access to a wireless communication network is exemplified in Fig. 4. Base station 12 comprises processing circuit 403 configured to encode system information indicating the second available resource of the based channel. in contention relative to the first available resource of the contention-based channel. Also, base station 12 comprises TX circuit 404 configured to broadcast system information. The contention-based channel corresponds, in some embodiments, to a random access channel, RACH, or to a common Enhanced Dedicated Channel, E-DCH. Furthermore, the system information can be comprised in a System Information Block type 5, SIB5. The second available resource, in some embodiments, is indicated in an ordered list of resources as a function of a position of the first available resource in the ordered list. Ordered list can define Enhanced Dedicated Channel, E-DCH common resources. Each E-DCH Resource may, in turn, be defined by a Soffset information element, a Fractional Dedicated Physical Control Channel code number information element, F-DPCH and an Acknowledgment Indicator Channel information. E-DCH Hybrid Automatic Repetition Request Receipt, E-HICH for a common E-DCH information element. In some embodiments, the position of the second available resources in the ordered list is defined by a default value in the Soffset information element. The default value can be a function of the position of the second available resource within the ordered list; a function of a "Soffset" value from a previous first available resource; or a function of the position of the second available resource and an offset value. The offset value is a Soffset value of the first available resource. The F-DPCH code number information element may be the same for up to ten common E-DCH resources. In some embodiments the E-HICH information for a common E-DCH information element is defined by a pipeline code and a signature sequence. A default value of the signature sequence can be a function of the position of the second available resource within the ordered list; a function of a "Signature Sequence" value from a previous first available resource; or a function of the position of the second available resource and the value of "Signature Sequence" of a previous first available resource. In some embodiments a pipeline code
ES 2 534 612 T3 of the second available resource is equal to a channelization code of the first available resource. The second available resource, in some embodiments, is defined by a value in an information element of a scrambling code of an uplink Dedicated Physical Control Channel. The value may be a function of the position of the second available resource within the ordered list of common E-DCH resources; a function of a value in an information element of a scrambling code of an uplink Dedicated Physical Control Channel of a previous first available resource; or a function of the position of the second available resource and a value of "Uplink DPCH code information for common E-DPC" in the information element of a scrambling code of an uplink Dedicated Physical Control Channel of the first prior available resource.
Fig. 5 is a schematic flow diagram depicting a method in a mobile terminal for requesting access to the wireless communication system in accordance with embodiments herein.
Step 501. The mobile terminal receives the broadcast system information indicating a first available resource of a contention-based channel. In some embodiments, the contention-based channel corresponds to a random access channel, RACH, or a common Enhanced Dedicated Channel, E-DCH. In some embodiments, the received broadcast system information is comprised of a System Information Block type 5, SIB5.
Step 502. Mobile terminal 10 derives a second available resource from the contention-based channel based on the first available resource from the contention-based channel. A common E-DCH resource can be defined as a UL scrambling code, an F-DPCH code number and "Soffset" timing offset, E-HICH channelization codes and signature sequence, and so on.
In some embodiments, the second available resource is 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 is defining common Enhanced Dedicated Channel, E-DCH resources, that each E-DCH Resource is defined by a Soffset information element, a Physical Control Channel code number information element Fractional Dedicated, F-DPCH and an E-DCH Hybrid Automatic Repeat Request Acknowledgment Indicator Channel information element, E-HICH, for common E-DCH
In some embodiments, the position of the second available resource in the ordered list is defined by a default value in the Soffset information element, the default value of which is a function of the position of the second available resource within the ordered list, a function of a “Soffset” value of a previous first available resource or a function of the position of the second available resource and an offset value, whose offset value is a Soffset value of the first available resource.
In some embodiments, the F-DPCH code number information element is the same for up to ten common E-DCH resources.
In some embodiments, the E-HICH information for a common E-DCH information element is defined by a pipeline code and a signature sequence and a default value of the signature sequence is a function of the position of the second resource available within the ordered list, a function of a "Signature Sequence" value of a previous first available resource or a function of the position of the second available resource and the "Signature Sequence" value of a previous first available resource.
In some embodiments, a second available resource pipeline code equals a first available resource pipeline code.
In some embodiments, the second available resource is defined by a value in an information element of a scrambling code of an uplink Dedicated Physical Control Channel, the value of which is a function of the position of the second available resource within the list. ordered of common E-DCH resources, a function of a value in an information element of a scrambling code of an uplink Dedicated Physical Control Channel of a previous first available resource or a function of the position of the second available resource and a value of "code information of Uplink DPCH for Common E-DCH ”in the information element of a scrambling code of an uplink Dedicated Physical Control Channel of the previous first available resource.
Let us consider a specific example in the 3GPP specifications, whereby the available resources comprise a combination of a power control command channel time slot, a power control command channel encoding, and the like, with each component of a available resource that is indicated relative to a corresponding component of another available resource.
>> List of Common E-DCH Resource Configuration information
ES 2 534 612 T3
This IE is a list containing all defined common E-DCH resources. A maximum of 32 common E-DCH resources can be included in this list. For each defined common E-DCH resource, the following IE's are defined:
>>> Soffset
This IE is an IE MP whose value ranges from 0 to 9. This value indicates the specific range within the F-DPCH in which power control commands are included for a specific F-DPCH code.
Instead of being MP, this IE is set in various embodiments as MD. If IE is not present, "Soffset" takes a default value. The default value is a function of the position of the common E-DCH resource within the list, a function of the “Soffset” value from a previous common E-DCH resource instance, or a function of the position of the E-DCH resource. -Common DCH and the “Soffset” value from a previous common E-DCH resource instance. The first common EDCH resource defined would occupy position 0 (or 1). The second defined common E-DCH resource would occupy position 1 (or 2). Similar reasoning would apply with the other defined resources.
A concrete embodiment would be, for example, if the value "Soffset" for the first case of the common E-DCH resource takes a default value and the rest of the common E-DCH resources take a value related to the last case.
For example, a simple formula for setting default values for each defined common EDCH resource is presented below.
Soffset = (common E-DCH resource list position + offset) mod 10 where “offset” is the value of the last case of the “Soffset” IE. If the IE "Soffset" was not present in the first case, "offset" is equal to zero.
"Common E-DCH Resource List Position" indicates the number of Common E-DCH Resource Configuration Information in order of appearance. The value of the "common E-DCH resource list position" can be zero (or one) for the first case.
If IE is present, the designated value overwrites the default value.
>>> F-DPCH code number
This IE indicates the code to be used for the F-DPCH.
Instead of being MP, this IE is optional, conditional on a value.
If the encoding presented for the Soffset is applied, potentially only three instances of the F-DPCh code number are needed, once for every 10 common E-DCH resources. Therefore, in the best configuration, only three cases would need to be present.
Therefore, this IE is in various embodiments fixed as conditional on a value (CV) so that this IE is necessarily present for the first occurrence. Alternatively, it should be present for the first occurrence or if the default value is equal to zero. Otherwise this IE is optional. Also, if this IE is not present, the value is equal to the last occurrence of this IE.
If IE is present, the designated value overwrites the default value.
>>>> E-HICH information
E-HICH information contains two additional IE's. Changes in this IE would imply impacts on Publication 6 and Publication 7 of the 3GPP standards. In order to avoid impacts in earlier versions, a new IE can be used instead: “E-HICH information for common E-DCH”. Only two IE would be needed as this feature only applies to FDD.
>>> E-HICH information for common E-DCH
Pipeline code
This IE can be set as an IE conditioned to a 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.
If IE is present, the designated value overwrites the default value.
Signature sequence
ES 2 534 612 T3
The value of this IE is a number between 0 and 39. This IE is set in various embodiments as MD. If IE is not present, "Signature Sequence" takes a default value.
The default value is a function of the position of the common E-DCH resource within the list, a function of the “Signature Sequence” value of a previous common E-DCH resource instance, or a function of the position of the common E-DCH resource and the “Signature Sequence” value from a previous common E-DCH resource instance. The first defined common E-DCH resource would occupy position 0 (or 1). The second defined common E-DCH resource would occupy position 1 (or 2). Similar reasoning would apply with the other defined resources. A specific implementation can be, for example, if the "Signature Sequence" for the first case of the common E-DCH resource takes a default value and the rest of the common E-DCH resources take a value based on the last case from IE.
For example, a simple formula is presented below to set default values for each defined common EDCH resource where IE is not present.
Signature Sequence = (common E-DCH resource list position + offset) mod 40 where “offset” is the value of the last occurrence of the “Signature Sequence” IE. If "Signature Sequence" was not present in the first case, "offset" is equal to zero.
"Common E-DCH Resource List Position" indicates the number of Common E-DCH Resource Configuration Information in order of appearance. The value of the "common E-DCH resource list position" is zero (or one) for the first case.
If IE is present, the designated value overwrites the default value.
>>> Uplink DPCH code information for common E-DCH
Scrambling code number is a present value MP. This IE takes a relatively large number of bits for each common E-DCH resource. This IE is changed in some embodiments to condition a value (CV) instead, avoiding including such a large number of bits per configured common E-DCH resource.
Conditioned to a value would mean that this IE is necessarily present for the first occurrence. Otherwise this IE is optional. Also, 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 common E-DCH resource within the list of common E-DCH resources, a function of the "Uplink DPCH code information for common E-DCH" value of a previous common E-DCH resource case or a function of the position of the common E-DCH resource and the value of "Uplink DPCH code information for common E-DCH" of an E-DCH resource case previous common. The following formula illustrates how the default values can be set if IE is not included:
Scrambling code number = common E-DCH resource list position + offset where offset is the value of the last occurrence of the IE "Scrambling Code Number". If "displacement" was not present in the first case or occurrence, "displacement" is equal to zero.
Common E-DCH Resource List Position indicates the number of Common E-DCH Resource Configuration Information in order of appearance. The value of the "common E-DCH resource list position" is zero (or 1) for the first case.
If IE is present, the designated value overwrites the default value.
>> E-DPDCH information
E-DCH Minimum Set E-TFCI
This IE is required by default. If this IE is omitted, it means that there is no minimum E-TFCI set.
In the case of E-DCH in CELL_FACH and Idle Mode, the UE will always send its message, especially CCCH messages. Otherwise the UE will crash and potentially the UE will be dropped. It seems obvious that for E-DCH in CELL_FACH and Idle Mode, the E-DCH minimum set E-TFCI will always be included and a number above zero must be required (E-TFCI Index 0 would only allow the UE to send the Programming Information).
Therefore, the semantic description can be modified so that for CELL_FACH and Idle Mode (or for Enhanced Uplink in CELL_FACH and Idle Mode), if IE is not included, the E-DCH minimum set E-TFCI is set to a defined value. The only restriction on this value is that the value belongs to the set of values defined in the E-TFCI table. The specific table to be used is indicated in the IE "E-TFCI table index" also included in the IE "E-DPDCH Information". As mentioned before, the value of E-TFCI zero only allows the UE to transmit the Programming Information. Therefore, the minimum E-TFCI value
Reasonable ES 2 534 612 T3 so that the UE can transmit higher layer or user control data is the value of ETFCI 1.
If IE is present, the designated values override the default value.
>> PRACH Preamble Control Parameters for Enhanced Uplink
Available Signatures
This is a bit string IE and each bit indicates whether or not a signature is used. The signatures configured for RACH and included in the IE "Available Signatures" present in the IE "PRACH Information (for RACH)". These signatures cannot be used for Enhanced Uplink in CELL_FACH and Idle Mode. The IE "PRACH Information (for RACH)" is included in the IE "List of PRACH System Information" which is carried in SIB5. "List of PRACH System Information", "PRACH Information (for RACH)" and "Available Signatures" are IE mandatory. Therefore, they will always be included in SIB5.
The IE "Available Signatures" contained in the IE "PRACH Preamble Control Parameters for Enhanced Uplink" is also a mandatory present value; 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 "Available Signatures" present in the IE "PRACH Information (for RACH)".
As an example, the default value in different embodiments is a "REVERSE" or "NO" function operation of the bit string values included in "Available Signatures" present in the IE "PRACH Information (for RACH)".
An illustrative example is presented to clarify the concept. If the value of the IE "Available Signatures" included in the IE "PrAcH Information (for RACH)" is: 1111111100000000, then the default value of the IE "Available Signatures" contained in the IE "Common E-DCH System Information ”Would be the inverse bit operation of (1111111100000000) which is equal to 0000000011111111. Therefore, the IE "available signatures" is set to mandatory by default (MD) and the semantics of the description would say that the default value is the reverse bit string indicated in the IE "Available signatures" in the IE "Information of PRACH (for RACH) ”. In other words, the signatures available for Enhanced Uplink in CELL_FACH are those signatures that are not used for RACH, unless IE is present.
By doing so, the base station 12 suppresses including this IE in the IE "PRACH Preamble Control Parameters for Enhanced Uplink" and thereby reduces the downlink control signaling. A mobile terminal 18 that does not receive such an IE nevertheless sets the IE to a default value described above. If IE is present, the designated values override the default value.
Preamble scrambling code number
This IE is also included in the IE "PRACH Information (for RACH)". The embodiments herein teach that the scrambling code for the common E-DCH is the same as that of the RACh, at least by default. If different, the new Preamble Scrambling Code Number in various embodiments is a function of the Preamble Scrambling Code Number present in the "PRACH Information (for RACH)" IE. Therefore, this IE is MD in some embodiments and by default equal to the IE "Preamble scrambling code number" indicated in the IE "PRACH Information (for RACH)" and is otherwise a function of the IE "Number of Preamble Scrambling Code ”indicated in the IE“ PRACH Information (for RACH) ”.
As in the previous case, the base station 12 refrains from including this IE in the IE "PRACH Preamble Control Parameters for Enhanced Uplink" and thereby reduces the downlink control signaling. A mobile terminal 18 that does not receive such an IE however sets the IE to a default value described above. If IE is present, the designated values override the default value.
Sub Channel Number Available
This IE is a bit string. Each bit indicates availability of 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 corresponding sub channel is available and the value 0 indicates that it is not available.
This IE is also included in the IE "PRACH Information (for RACH)". This IE is also set to MD in some embodiments. The mandatory default is a function of the IE "PRACH Information (for RACH)".
For example, this IE can be set equal to the IE "Available Sub Channel Number" indicated in the IE "PRACH Information (for RACH)". In another approach, the default value may be the REVERSE (or NO) function of the IE "Sub Channel Number Available" indicated in the IE "PRACH Information (for RACH)".
As in the previous case, the base station 12 refrains from including this IE in the IE "PRACH Preamble Control Parameters for Enhanced Uplink" and thereby reduces the link control signaling.
ES 2 534 612 T3 downstream. A mobile terminal 18 that does not receive such an IE however sets the IE to a default value described above. If IE is present, the designated values override the default value.
Applying the coding suggested above, the structure of the IE "PRACH Preamble Control Parameters for Enhanced Uplink" and other implicated IEs would be translated as shown below, the affected IEs are indicated with underlined text and the unaffected IEs are define in reference to the Technical Specification (TS) 25.331 section 10 version 10.0.0 of the 3GPP:

Step 503. Mobile terminal 10 transmits an access request preamble correlated to the second available resource. In this way, the mobile terminal 10 requests access to the wireless communication system. In some embodiments, the mobile terminal randomly selects the access request preamble. Furthermore, the mobile terminal 10 may, when it receives an acknowledgment of the transmitted access request preamble, transmit uplink data on the contention-based channel using the second available resource.
Processing at mobile terminal 10 may further include receiving system information that directly indicates access request preambles for a contention-based first uplink channel. Processing continues by deriving the access request preambles for a contention-based second uplink channel based on, or as a function of, the directly indicated preambles. In one or more embodiments, the processing further includes randomly selecting one of the derived access request preambles, and then transmitting the selected preamble to request access to the contention-based second uplink channel.
FIG. 6 is a block diagram depicting mobile terminal 10 according to embodiments herein. Mobile terminal 10 is configured to generally perform the method illustrated in FIG. 5. Mobile terminal 10 may include one or more transmit / receive antennas 601, along with transmitter (TX) circuit 602 and receiver circuit (RX). 603 associated, respectively, and includes one or more processing circuitry 604. The RX circuit 603 is configured to receive from the base station 12, through the reception antennas 601, the broadcast system information indicating a first available resource of a CB channel. The processing circuit 604 of the mobile terminal 10 can be configured to then derive information for a second available resource from the CB channel based on, or as a function of, the first. This may entail, for example, deriving information for the second available resource according to a predetermined 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 that describes the resources. The processing circuit 604 may optionally in some embodiments randomly select an access request preamble corresponding to a second available resource of a contention-based uplink channel. The TX circuit 602 can then transmit the selected preamble, and the RX circuit 603 can receive a positive acknowledgment. Whether or not performed in response to the transmitted selected preamble, the processing circuit 604 may derive system information for a second available resource from the contention-based second channel, eg uplink channel, based on, or as a function. de, the first available resource. Finally, the TX circuit 602 may in various embodiments terminate the transmission of uplink data on the contention-based second uplink channel using the second available resource.
In some embodiments, the received system information may directly indicate the access request preambles for a channel, eg, the legacy CB channel such as an RACH. The processing circuit 604 may then be configured to derive the access request preambles for the other channel, for example the non-legacy CB channel, such as an E-DCH, based on, or as a function of, the indicated preambles. directly. In some embodiments, processing circuit 604 is further configured to randomly select from derived access request preambles, after which TX circuit 602 is configured to transmit the selected preamble to base station 12, in order to request access to the associated CB channel
ES 2 534 612 T3
In Fig. 6, the mobile terminal receives system information indicating a first available resource of the contention-based second uplink channel. In some embodiments, the processing circuitry may optionally include randomly selecting an access request preamble that corresponds to a second available resource of the contention-based second uplink channel, transmitting the selected preamble, and receiving a positive acknowledgment. Processing circuit 604 then derives system information for a second available resource from the contention-based second uplink channel based on, or as a function of, the first available resource. Finally, the processing circuit 604 may, in various embodiments, terminate the transmission of uplink data on the contention-based second uplink channel using the second resource available through the TX circuit 602.
Thus, the mobile terminal 10 for requesting access to a wireless communication system comprises the receiver circuit 603 configured to receive broadcast system information indicating the first available resource of the contention-based channel. Mobile terminal 10 further comprises processing circuit 604 configured to bypass the second available resource of the contention-based channel based on the first available resource of the contention-based channel. Processing circuit 604 may further be configured to transmit an access request preamble mapped to the second available resource. The processing circuit 604, in some embodiments, may further be configured to randomly select the access request preamble. Additionally, the processing circuit 604 may further be configured to, when an acknowledgment of the transmitted access request preamble is received, transmit uplink data on the contention-based channel using the second available resource. In some embodiments, the contention-based channel corresponds to a random access channel, RACH, or a common Enhanced Dedicated Channel, E-DCH. The received broadcast system information may be comprised in a System Information Block type 5, SIB5. The second available resource can be indicated in the 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 is defining common Enhanced Dedicated Channel, E-DCH, resources. Each E-DCH Resource can be defined by a Soffset information element, a Fractional Dedicated Physical Control Channel code number information element, F-DPCH and an Acknowledgment Indicator Channel information element E-DCH Hybrid Automatic Repeat Request, E-HICH, for common EDCH. In some embodiments, the position of the second available resource in the ordered list is defined by a default value in the Soffset information element. The default value is a function of the position of the second available resource within the ordered list; a function of a "Soffset" value from a previous first available resource; or a function of the position of the second available resource and an offset value. Where the offset value is a Soffset value of the first available resource. In some embodiments, the F-DPCH code number information element may be the same for up to ten common E-DCH resources. The E-HICH information for a common E-DCH information element is defined, in some embodiments, by a pipeline code and a sequence of signatures. A default value of the signature sequence is a function of the position of the second available resource within the ordered list; a function of a "Signature Sequence" value from a previous first available resource; or a function of the position of the second available resource and the value of "Signature Sequence" of a previous first available resource. A channel code of the second available resource can be equal to a channel code of the first available resource. The second available resource can be defined by a value in an information element of a scrambling code of an uplink Dedicated Physical Control Channel, whose value is a function of the position of the second available resource within the ordered list of resources. of common E-DCH, a function of a value in an information element of a scrambling code of an uplink Dedicated Physical Control Channel of a previous first available resource or a function of the position of the second available resource and a value of "code information of Uplink DPCH for Common E-DCH ”in the information element of a scrambling code of an uplink Dedicated Physical Control Channel of the previous first available resource.
