摘要:
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.

A method and apparatus for generating measurement report and transmitting the measurement report via a random access channel in a CELL_FACH state are disclosed. A wireless transmit/receive unit (WTRU) in CELL_PCH or URA_PCH state may transition to CELL_FACH state. The measurement report may be transmitted in response to receiving a dedicated high speed downlink shared channel (HS-DSCH) using a HS-DSCH radio network temporary identity (H-RNTI). The measurement report may be transmitted periodically and may include a channel quality indicator (CQI). The H-RNTI may be a dedicated H-RNTI. The measurement report may be transmitted when the WTRU has data to transmit, during cell reselection, or during cell update.

A method and apparatus for supporting uplink (UL) protocol changes includes reconfiguring a medium access control (MAC) protocol. A hybrid automatic repeat request (HARM) process is flushed, and a MAC-e/es reset is performed.

A method and apparatus for acknowledge mode data (AMD) re-segmentation are disclosed. An AMD protocol data unit (PDU) is generated from at least one RLC SDU. The AMD PDU size is within a flexible maximum AMD PDU size. The original AMD PDU is stored in a retransmission buffer, and transmitted. If transmission of the original AMD PDU fails and the original AMD PDU size is larger than an updated maximum AMD PDU size, the original AMD PDU is segmented to segmented AMD PDUs. If transmission of one of the segmented AMD PDUs fails, the original AMD PDU may be re-segmented to smaller size AMD PDUs.
摘要:
A method and apparatus provide for the control of wireless communication signals over an enhanced dedicated channel (E-DCH) resource while operating in the CELL_FACH state with an allocated E-DCH radio network temporary identifier (E-RNTI). A determination is made that a periodic cell update timer is expired. In response to the periodic cell update timer expiring, a determination is made whether the WTRU has an allocated E-DCH resource. If the WTRU has an allocated E-DCH resource, the periodic cell update timer is re-started without performing a periodic cell update.

A method and apparatus for performing a serving high speed downlink shared channel (HS-DSCH) cell change from a source cell to a target cell are disclosed. A wireless transmit/receive unit (WTRU) may be pre-configured with HS-DSCH configuration for the target cell. The WTRU may start monitoring a high speed shared control channel (HS-SCCH) on the target cell using the pre-loaded HS-DSCH configuration for the target cell on a condition that a measurement report is triggered by the event 1D. The WTRU may initiate a timer when the WTRU starts monitoring the HS-SCCH on the target cell.
摘要:
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.

An apparatus and method of transmitting a circuit switched (CS) voice application via an enhanced dedicated channel (E-DCH), implemented in a wireless transmit/receive unit (WTRU). The method includes receiving a grant; performing an E-TFC selection procedure based on the grant, wherein a number of bits that may be transmitted over an enhanced dedicated channel (E-DCH) is determined, determining an adaptive multi-rate (AMR) codec bit-rate based on the number of bits that may be transmitted over the E-DCH, generating AMR voice packets based on the determined AMR codec bit rate, and submitting the AMR voice packets to lower layers for transmission over the E-DCH.
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.
