Abstract: A method and apparatus for radio link control (RLC) re-segmentation are disclosed. An original RLC protocol data unit (PDU) is generated from at least one RLC service data unit (SDU). The RLC PDU size is within a flexible maximum RLC PDU size. The original RLC PDU is stored in a retransmission buffer. If transmission of the original RLC PDU fails and the original RLC PDU size is larger than an updated maximum RLC PDU size, the original RLC PDU is segmented to segmented RLC PDUs. If transmission of one of the segmented RLC PDUs fails, the original RLC PDU may be re-segmented to smaller size RLC PDUs, or the segmented RLC PDU may be sub-segmented. Alternatively, the failed RLC PDU may be processes as an RLC SDU to generate encapsulating RLC PDUs for carrying the RLC PDU. Alternatively, an RLC SDU corresponding to the failed RLC PDU may be re-segmented.

Abstract: Methods and apparatus are disclosed to facilitate wireless communications between a wireless transmit receive unit (WTRU), legacy base stations and base stations using different operating parameters, such as evolved high speed packet access (HSPA) systems Third Generation Partnership Project ((3GPP) Release 7, Release 8 and beyond). Preferred WTRUs are configured with a medium access control (MAC) sub-layer component having a subcomponent with HARQ buffers, such as a subcomponent configured to provide MAC-es and MAC-e functionality and/or MAC-is and MACi functionality that include hybrid automatic repeat request (HARQ) processes, some of which are preferably operable with enhanced dedicated transport channels (E-DCH). The WTRUs are preferably configured such that they reconfigure their MAC subcomponents during soft handover while minimizing induced latency and data losses associated with HARQ processes. In some embodiments, the WTRUs are configured to prevent flushing of HARQ process buffers in soft handover scenarios with a Node B that does not support UL enhancements, e.g. higher order modulation (HOM). In other embodiments, flushing of HARQ processes is used but amelioration of adverse effects is addressed.

Abstract: A method and an apparatus are provided for efficient transmission of low-data-rate packet services in a multiple-input multiple-output (MIMO) mode of operations in the presence of high-data-rate packet services. Precoding weight information (PWI) is signaled implicitly to a wireless transmit receive unit (WTRU). A precoding weight vector is signaled in a high speed shared control channel less (HS-SCCH-less) transmission using a new HS-SCCH type P. This explicit PWI signaling approach transmits the PWI with minimum power overhead. The data carried in the HS-SCCH type P is encoded to minimize the required transmitted power. A channel type HS-SCCH type 2M is also described.

Abstract: Paging in a HSDPA connected mode CELL_PCH or URA-PCH state. A WTRU is configured to select various PICH information that is broadcast by a base station (in the HSDPA associated PICH info" information element of a System Information block 5/5bis) by compiling a list of cabdidate PICHs, and selecting a PICH info based on the U-RNTI of the WTRU. The WTRU is configured to receive paging messages, based on the selected PICH information. In one embodiment, a preferred WTRU is configured to receive paging messages, based on a PICH, a HS-SCCH, and a HS-PDSCH. In another embodiment, a preferred WTRU is configured to receive paging messages, based on a PICH and a HS-PDSCH. In both embodiments, a time delay parameter (for timing the transmission of the PICH and the transmission of a paging message) is preferably used so that the WTRU may listen for either the HS-SCCH or HS-PDSCH for a period of time and return to a sleep mode if no paging message is received.

Abstract: A variety of wireless communication methods and apparatus for supporting reconfiguration of radio link control (RLC) parameters are disclosed. A radio resource control (RRC) reconfiguration message is generated that indicates that an RLC unit in a wireless transmit/receive unit (WTRU) or a universal terrestrial radio access network (UTRAN) should be reconfigured from supporting flexible size RLC protocol data units (PDUs) to supporting fixed size RLC PDUs. If an information element (IE) "one sided RLC re-establishment" is present in the RRC reconfiguration message, only a receiving side subassembly in the RLC unit is re-established. Otherwise, both the receiving side subassembly and a transmitting side subassembly in the RLC unit are re-established. Flexible size RLC PDUs may be discarded and a message indicating the discarded flexible size RLC PDUs may be transmitted. The flexible size RLC PDUs may be modified such that they correspond to a set of pre-defined sizes.

Abstract: A method and apparatus for cell update while in a Cell_FACH state are disclosed. After selecting a target cell, system information is read from the target cell including high speed downlink shared channel (HS-DSCH) common system information. A radio network temporary identity (RNTI) received in a source cell is cleared and a variable HS_DSCH_RECEPTION is set to TRUE. An HS-DSCH medium access control (MAC-hs) entity is configured based on the HS-DSCH common system information. High speed downlink packet access (HSDPA) transmission is then received in the target cell. A CELL UPDATE message is sent to notify of a cell change. The HSDPA transmission may be received using a common H-RNTI broadcast in the system information, a reserved H-RNTI as requested in a CELL UPDATE message, or a temporary identity which is a subset of a U-RNTI. The MAC-hs entity may be reset.

Abstract: A method and apparatus for controlling an optimization of handover procedures between universal terrestrial radio access (UTRA) release 6 (R6) cells and UTRA release 7 (R7) cells are disclosed. When a wireless transmit/receive unit (WTRU) is moving between an R6 cell and an R7 cell, or between R7 cells, a handover is initiated from a source Node-B to a target Node-B. In the R7 cell, the enhanced medium access control (MAC) functionality including flexible radio link control (RLC) protocol data unit (PDU) size and high speed MAC (MAC-hs) segmentation and multiplexing of different priority queues are supported. After the handover, a MAC layer and/or an RLC layer are reconfigured or reset based on functionality supported by the target Node-B.

Abstract: A method and apparatus for uplink transmission over a non-contentious shared feedback channel are disclosed, wherein the parameters of the uplink transmission are determined by the parameters of a downlink transmission. A new uplink channel, called a physical shared uplink feedback channel (PSUFCH) is used for uplink transmission such as feedback information in response to a downlink transmission on a fast shared data channel. The content of the feedback information may be general, e.g. an ACK/NACK or a channel quality indicator (CQI). The PSUFCH is transmitted using power ramping that terminates upon reception of a downlink ACK (DLACK) from a Node-B. No ambiguity resolution is required due to the non-contentious and deterministic mapping of the uplink channel resources.
