System level information for discontinuous reception, cell reselection and rach

[0001] The present invention relates to wireless communication.

BACKGROUND [0002] The Third Generation Partnership Project (3GPP) initiated the Long Term Evolution (LTE) program to provide new technology, new network architecture, new configurations and new applications and services to wireless cellular networks in order to provide improved spectral performance and faster user experience .

[0003] In order for the wireless transceiver (WTRU) to perform various procedures related to rest, monitoring of paging cycles, cell reselection or use of the random access channel (RACH), the network should normally signal a number of parameters to the WTRU in system information messages. Some of these parameters can also be used when the WTRU is in an active state, including but not limited to reduced neighbor cell lists, measurement reporting and handover parameters. There is a need to combine all the necessary parameters and group them into system information messages for use by the WTRU in standby and reselect procedures or RACH procedures.

[0004] In the core network (CN) domain system information, information for intermittent reception (DRX) would normally be signaled to the WTRU in idle mode in the information element (IE) (e.g., CN_DRX_cycle_length_coefficient). However, DRX exists in both active and idle modes. Hence, it would be beneficial to signal DRX cycle lengths for active mode.

[0005] When WTRU resides in a cell, it regularly looks for better cells according to a set of criteria. When a better cell is found, this cell is selected. In an LTE system with only two LTE_Idle and LTE_active states, the WTRU can only reselect the cell in the LTE_Idle state. The WTRU uses parameters transmitted from the system, including but not limited to the following parameters, which are transmitted in the block (SIB) of system information, such as SIB 3, SIB 4 and / or SIB 11:

• Q_hyst1s: used in serving cell classification based on RSCP.

55P35677PL00

• Q_hyst2s : used in serving cell classification based on Ec / Io.

• Q_qualmin: measurement of the minimum required quality based on Ec / Io.

• Qrxlevmin: measurement of the minimum required quality based on the measurement of received signal power (eg, received signal code power (RSCP)).

• DeltaQrxlevmin: (conditionally for the Delta value) When present, the actual value ^Qrxlevmin ⁺ DeltaQrxlevmin.

• UE_TXPWR_MAX_RACH: maximum allowable uplink power (UL) TX • S_intrasrch (optional): measures "intra-frequency neighbor cells" when S_qual <Sintrasearch, where Squal is based on the ratio of the measured signal to interference of the respective cell, measured by WTRU minus Qqualmin.

• Sintersrch (optional): measures "inter-frequency neighbor cells" when Squal < ^SInterSearch^. • SsearchHCS (optional): measures "inter-Hierarchal Cell Structure" (HCS) / "interfrequency neighbor cells" when Squal <SsearchHCS.

• SHCS, RAT (optional): measures "inter-Hierarchal Cell Structure" (HCS) / "RAT neighbor cells" when Squal <SHCS, RAT.

• Slimit, SearchRAT (optional): This threshold is used in the measurement rules for cell reselection when HCS is used. Specifies the RAT-specific threshold (in dB) in the serving UTRA cell above which the UE may choose not to make any inter-RAT measurements in RAT "m". US 2007/0178875 A1 discloses a system for controlling the initiation time of an intermittent receive cycle, DRX, based on a calculated value with respect to a wireless signal received during the active period of a previous DRX cycle.

[0006] 3GPP TS 25.331 version 7.5.0, Release 7, discloses Radio Resource Control Protocol to the UE-UTRAN radio interface.

SUMMARY [0007] A method of processing information for implementation by a wireless transceiver unit, WTRU, is disclosed in independent claim 1.

The corresponding WTRU apparatus is disclosed by the independent claim 12. Further preferred embodiments are disclosed by the attached dependent claims.

BRIEF DESCRIPTION OF THE DRAWING

55P35677PL00

[0008] A more detailed understanding can be obtained from the following description, given as an example in connection with the accompanying drawings, in which:

Figure 1 shows an intermittent reception cycle (DRX); and Figure 2 shows the configuration of the stack of protocol layers for the wireless transceiver receiving system level information from the evolved Node-B.

DETAILED DESCRIPTION [0009] When used herein, the term "wireless transceiver unit (WTRU)" includes, but is not limited to, a user device (UE), mobile station, fixed or mobile subscriber unit, pager, cell phone, personal digital assistant (PDA), computer, or any other type of user device capable of working in a wireless environment. When referred to herein, the term "base station" includes, but is not limited to, a Node-B, field controller, access point (AP), or any other type of connecting device capable of operating in a wireless environment. [0010] Figure 1 shows a WTRU 101 containing a stack of protocol layers that includes the following layers: radio resource control RRC 102, radio link control (RLC) 103, medium access control (MAC) 104, packet data convergence protocol (PDCP) 105, and physical layer (PHY) 106. These layer units can be implemented as a single processor or as separate processors. WTRU 101 receives system level information from evolved NodeB (eNB) 121 in wireless downlink signal 111. System level information can be defined in units of system information blocks (SIBs) and the parameters of each SIB can be used by WTRU 101 for various processes, which will be explained in more detail. Parameters can be defined in groups of information elements (IE) that can be processed, for example by RRC 102 for the control operation of other layer units. One example includes RRC 102 receiving DRX parameters and then instructing PHY 106 to rest during parameters of a designated DRX cycle. In general, WTRU 101 receives and processes system level information, and performs the appropriate actions autonomously.

In the first example of defining SIB with system level information, system information block 1 (SIB1) may be defined by

55P35677PL00

The information elements and related information as shown in Table 1. Each of the IEs shown in Table 1, as well as all the tables presented herein, can be defined and provided to WTRU 101 as needed, which includes, but is not limited to to the following: mandatory, mandatory with the default value available, conditional on value, or optional.

<td>Timers and permanent WTRU in active (connected) mode</td><td>Timers and permanent WTRU in active (connected) mode</td><td></td>

[0012] As shown in Table 1, IE core network (CN) includes non-access stratum (NAS) common GSM-mobile application part (MAP) system information and domain information for the packet transmission (PS) domain. These IE inform WTRU 101 about the supporting CN and domain system. The LTE network only works in the packet data (PS) domain. Hence there is no need to keep any other domain information. Only signaling information about the PS domain is required.

[0013] In the LTE specification, DRX works in both explicit and implicit modes.

DRX parameters can be signaled by two IEs that transfer specific DRX parameters for each operating mode. IE can carry both DRX explicit mode parameters and DRX implicit mode parameters. These IE can be signaled

55P35677PL00

EP 2 186 269 B1 with the system information about the domain or may be transmitted with another message, such as, for example, the RRC_Connection_Command message.

[0014] Figure 2 shows a set of sequential DRX signal cycles in which the WTRU 101 has an active period and a rest period for the remainder of the DRX cycle, allowing the WTRU 101 to reduce battery consumption. The variable DRX parameters for defining the DRX cycle are the start time of the DRX cycle, the length of the active period, and the length of the DRX cycle. For LTE idle mode, WTRU 101 only monitors system paging during the active period. For LTE active mode, or for RRC connected mode, the WTRU 101 only receives data during the active period. DRX parameter settings may become necessary, for example, to overcome poor channel conditions or to increase data reception after the transition from the LTE idle state to the LTE active state. For DRX configuration, when WTRU 101 is in LTE active mode, the network may signal the same or different parameters than for WTRU 101 in LT idle mode. The network can also group parameters and identify the group with a DRX profile ID. This may enable the WTRU 101 signaling network to use a particular profile. Signaling received by WTRU101 can be done before RRC or MAC signaling and can provide a DRX cycle start time as shown in Figure 2.

[0015] Table 2 shows an example of the DRX configuration of the LTE idle mode and LTE active mode and associated parameters for the embodiment for which the WTRU 101 is configured for receiving and processing. IE for the CN DRX cycle length in idle mode LTE indicates the length of the entire DRX cycle for WRTU 101 to use when receiving paging in idle mode. IE for LTE active mode parameters indicates to the WTRU 101 whether the LTE active mode parameters are to be the same as the idle mode parameters or other than the idle mode parameters. When different, the network may then specify a different set of active mode parameters. To enable WTRU 101 to synchronize with the DRX cycle, IE is defined for the start time of the DRX cycle. In this example, the cell system frame number (SFN) is used as a reference for the DRX cycle start time. The IE of choice, Choice Signaling Method, is defined by the network and received by WTRU 101 to indicate the type of DRX signaling method used, which is either of the explicit or implicit type, described in more detail in

55P35677PL00

EP 2 186 269 B1 with reference to Tables 3 and 4.

DRX can indicate either full configuration mode or predefined configuration mode. For full configuration mode, the network provides all parameters

DRX to WTRU 101. In the predefined configuration mode, WTRU 101 uses the default DRX parameters that are predefined by the network. Information item

The DRX profile ID can be used to define the various DRX profiles that can

EP 2 186 269 B1 to change DRX length and other parameters during various procedures, including 3GPP to non-3GPP handovers.

[0017] Table 4 provides a summary of an example configuration of information elements used in implicit DRX signaling. As shown, the DRX implicit IE and transition list have many examples in WTRU 101 signaling, one for the maximum number of DRX states. Similar to explicit DRX explained above, there is IE choice here for the DRX configuration mode, either for the predefined configuration or for the full configuration. In full configuration mode, IE triggers Trigger-UP-1, Trigger-Down-1 and TriggerDown-2. IE Trigger-UP-1 IE indicates that WTRU 101 should be moved to the next one

55P35677PL00

A higher level DRX state (i.e., a longer DRX cycle). IE Trigger-Down-1 IE is the trigger mechanism for WTRU 101 to transfer to the next lower level DRX state (i.e. shorter DRX cycle). For IE Trigger-Down-2, WTRU 101 receives the trigger mechanism to move to the shortest DRX cycle, Level-1.

For each of these IE triggers, the IE selection for the trigger mechanism includes either a timer or measurement event as summarized in Table 5. When a timer trigger mechanism is used, IE timer values, Implicit-DRX-triggering-timer may be included. For a trigger measurement event, an implicit DRX trigger event may be included, based on traffic flow and / or inter-frequency, intra-frequency, inter-RAT, intra-RAT measurement events, and IE may be included for a threshold value up to use for the measurement event.

[0018] Additional IE provided to WTRU 101 for defining the DRX cycle may include a DRX cycle length, active period length, active period position, and active period start subframe. For IE DRX cycle length, the parameter indicates the DRX cycle length for LTE active in system frame units and indicates if this DRX parameter is different from the LTE mode parameter idle IE length

55P35677PL00

The active period indicates the length of the active cycle in Podzamki for the LTE active mode, and whether the parameter is different from the LTE idle mode parameter. IE of the active period position indicates whether the active period is at the beginning or end of the DRX cycle or if the parameter is other than the LTE idle mode parameter. When the active period does not start at the frame border, the IE of the start of the active period provides the number of the Podzamce at which the active period begins.

[0019] In another embodiment, the cell selection and reselection parameters are defined and transmitted, for example, in SIB 3, or in one of the other SIBs defined in 3GPP specifications. After receiving and processing these 10 parameters, WTRU 101 autonomously performs cell selection / reselection operations.

Tables 6 and 7 provide a summary of an example IE configuration containing cell selection and reselection parameters.

WTRU allocated to the corresponding public land mobile network (PLMN), which is identified in IE "multiplePLMNs" in IE "Multiple PLMN List" in the master information block (MIB). When IE "Alternative Access Restriction Parameters for All" is selected, the set of common WTRU 101 Access Restriction Parameters is selected, which is applied to all PLMNs in IE "multiple

PLMNs ". Because there is one PS domain, parameters for the CS domain are not specified.

[0021] As shown in Table 7, WTRU 101 can receive IE for measuring the quality of cell selection and reselection based on RSRP and / or RSRQ, IE for radio access technology (RAT) of the selection candidate cell, and IE Treselection, which indicates the parameter re-selection time. With regard to IE Qhyst, WTRU 101 can receive the following scaling factors: IE, which indicates a Speed-dependent scaling factor, Inter-frequency Speed-dependent scaling factor, and Inter RAT Speed-dependent scaling factor. IE with a black list of neighbor cells may be obtained by the WTRU to indicate a list of neighbor cells banned by the reselection network.

55P35677PL00

In the cell, WTRU 101 may receive and process IE UTRAN_min or GERAN_Min, which indicate the minimum signal strength for the UTRAN or GERAN cell, respectively. IE Qoffset1 and Qoffset2 can be received by WTRU 101 to indicate measurements of cells performing biasing.

[0023] In another embodiment, the system level information for the PHY random access channel (PRACH) is defined by parameters in IE and contained in

55P35677PL00

EP 2 186 269 B1

SIB 5, or other SIB specified in 3GPP, to be received and processed by WTRU 101 for autonomous execution of RACH operations. Tables 8-10 provide a summary of sample configurations of such IE and related information.

[0024] As shown in Table 8, IE PRACH system information may be included in many instances from 1 to maxPRACH. IE PRACH information for RACH contains several IE, which are summarized in Table 9. IE non-dedicated RACH signature indicates dedicated and non-dedicated signatures allocated to WTRU 101, and contains several IE, which are summarized in Table 10. IE the RACH response window informs WTRU 101 about the number of subframes during which many RACH responses are to be received sent to WTRU 101. IE regarding PHY downlink control channel (PDCCH) information, "PDCCH-Info", provides PDCCH parameters for PRACH to WTRU 101, including IE summarized in Table 12. IE list routing area-radio network temporary identification (RA-RNTI), containing IE summarized in the Table

11, old information RNTI to WTRU 101 for routing area.

[0025] As shown in Table 9, WTRU 101 receives information parameters

PRACH for frequency division duplex (FDD) and time division duplex (TDD) operations. For FDD, WTRU 101 may receive an IE PRACH frequency position indicating an integer in the range from the edge of the lowest frequency of the carrier bandwidth. Alternatively, the integer value may range between negative and positive values ​​centered in the center of the carrier's frequency. Additional parameters received by WTRU 101 include IE PRACH burst type IE (e.g. burst type normal, extended or repeated) and IE of the Channel Coding parameter to identify the turbo code used. For TDD, WTRU 101 may receive an IE PRACH frame structure type and IE PRACH Burst Type IE to indicate, for example, a normal or extended burst type.

[0026] As shown in Table 10, WTRU 101 may receive a RACH parameter set defined according to the G1 group for dedicated RACH signatures, the G2 group for consecutive or bit mapped non-dedicated RACH signatures, or the G3 group for small messages, consecutive or bit mapped non-dedicated signatures RACH. Each RACH channel has typically 64 random access signatures from cyclic ZC codes whose generation / output is specified in 3GPP standards. For system information, signatures can be

55P35677PL00

EP 2 186 269 B1 identified by their indexes (0, ..., 63).

[0027] When there is a random access signature group whose signatures are all in turn in terms of signature index, it can be defined by [start index-a, range]. WTRU 101 knows and selects the signatures in the defined group because they are in turn. For example, WTRU 101 receives IE available dedicated G1 signatures, IE number of signatures with a value of 8, and IE signer index with a value of 8, then WTRU 101 can conclude that its RACH signature group is [8 15].

[0028] But when the random access signatures in the group are not in turn, the above IE mapping of index indexes is replaced by an alternative bit-mapped signature index shown in Table 10 as IE signature maps. For bit-mapped signature mapping, WTRU 101 receives a bit string that indicates the set of available signatures in the random access signature group according to a predefined signature map. The signature map IE uses a 64-bit bitmap, or the first start-index, and the next bitmap in the range.

[0029] Unlike the SIB mentioned above, the LT network could also transmit a SIG 16 message that could carry some configuration parameters that the WTRU 101 could read and use when entering the LTE system during a handover from another RAT (3GPP or non-3GPP) to LTE. Alternatively, the LTE system could transmit a SIB 16 message or some other analogous dedicated RRC message that would transfer parameters to be used for non-3GPP RAT during a handover from LTE to another RAT (3GPP or non-3GPP). Such a message could probably be transferred to the LTE system just before the handover procedure. This SIB 16 could contain a combination of parameters such as some of these DRX parameters, some RACH and reselection parameters, and other physical layer parameters that may give WTRU 101 some system knowledge.
