    摘要: 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.

    摘要: A method and apparatus for transmitting and receiving common logical channel and dedicated logical channel transmissions via a high speed downlink shared channel (HS-DSCH) are disclosed. A medium access control (MAC)-hs entity generates a MAC-hs protocol data unit (PDU) carrying a MAC-c/sh/m PDU and/or a MAC-d PDU. A UE-specific HS-DSCH radio network temporary identifier (H-RNTI) may be used for the MAC-d PDU, and a cell-specific H-RNTI may be used for the MAC-c/sh/b PDU. Alternatively, a cell-specific H-RNTI and one of a cell RNTI (C-RNTI) and a universal terrestrial radio access network RNTI (U-RNTI) may be used in a Cell_FACH state. The logical channel type and identity may be inserted in a MAC-hs PDU header or indicated by a distinct H-RNTI. A logical channel type for common logical channels may be identified in a MAC-c/sh/m PDU header. The logical channel type and identity may be identified by a queue identity.

    摘要: A method and apparatus are used to generate radio link control (RLC) protocol data units (PDUs). A data request for a logical channel is received as part of an enhanced dedicated channel (E-DCH) transport format combination (E-TFC) selection procedure in a medium access control (MAC). Upon determining the data field size, an RLC PDU is generated such that it matches the requested data from the E-TFC selection. The size of the RLC PDU generated can be greater than or equal to the minimum configured RLC PDU size (if data is available) and less than or equal to the maximum RLC PDU size. The data is then transmitted in the RLC PDU in a current transmission time interval (TTI).

    摘要: Efficient enhanced transport format combination (E-TFC) selection methods and apparatus support flexible radio link control (RLC) packet data unit (PDU) size and medium access control (MAC) layer segmentation. Methods for filling an enhanced medium access control (MAC-e) packet data unit (PDU) with data from logical channels as part of E-TFC selection are provided. In one embodiment, the E-TFC selection algorithm employs a single request from the MAC layer to the RLC layer to request the number of bits it is allowed to send for a logical channel to create enhanced MAC-e PDUs. In another embodiment, the MAC entity performs multiple requests to the RLC entity. In another embodiment, the MAC entity makes a single request to the RLC entity to create one or more enhanced MAC-e PDUs of a set size. A technique is also provided for maintaining a guaranteed bit rate (GBR) for non-scheduled data flows with variable-length headers.

    摘要: Enhanced MAC-es PDUs are created by concatenating enhanced MAC-es service data units (SDUs) based on higher layer PDUs and segments thereof, where segmentation information is included in the enhanced MAC-es headers. An enhanced MAC-e header is generated for each enhanced MAC-es PDU to describe information about the enhanced MAC-es PDU. An enhanced MAC-e PDU is created by concatenating enhanced MAC-es PDUs and enhanced MAC-e headers. An enhanced MAC-es header may include a Transmit Sequence Number (TSN) field, a Segmentation Description (SD) field, length (L) fields to indicate the length of each enhanced MAC-es SDU and/or logical channel indicator (LCH-ID) fields. An enhanced MAC-e header may include one or more logical channel indicator (LCH-ID) fields for corresponding enhanced MAC-es PDUs or MAC-s SDUs and length (L) fields.

    摘要: 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.
