摘要： The present invention is related to a method and system for sending and reducing uplink feedback signaling by a wireless transmit/receive unit (WTRU) related to transmission of multimedia broadcast multicast service (MBMS) data over a high speed downlink packet access (HSDPA) channel. A Node B may pre-allocate a time/frequency region or a common channelization code for the feedback. A triggering criterion for reporting a channel quality indicator (CQI) is set and WTRUs send a CQI to a Node B only if the triggering criterion is satisfied. The triggering criterion may be a current operating CQI value at the Node B, or based on erroneous transport block reception statistics, or a predetermined time period. A feedback reduction method related to ACK/NACK includes the WTRU sending an indication of an average number of transmissions needed to successfully decode the data instead of sending an ACK/NACK for every transmission interval.

摘要： A method and apparatus for dynamically configuring a memory for hybrid automatic repeat request (H-ARQ) processes in a receiving node to permit a more flexible H-ARQ memory configuration and improve the performance of H-ARQ processes. An H-ARQ memory in the receiving node is reserved for a plurality of H-ARQ processes. A transmitting node dynamically configures the H-ARQ memory in the receiving node for each H-ARQ transmission so that the memory requirement for a plurality of H-ARQ processes exceeds the H-ARQ memory capacity. If there is insufficient H-ARQ memory available to support H-ARQ transmissions, only a subset of the plurality of H-ARQ processes may be activated at a time. When there is insufficient H-ARQ memory for processing H-ARQ transmissions, a negative acknowledgement (NACK), an acknowledgement (ACK), nothing, and/or information indicating the reason for a failed transmission may be transmitted to a transmitting node.

摘要： A receiver sends hybrid automatic repeat request (H-ARQ) feedback for a current packet and at least one previous packet, whereby an error is detected based on the H-ARQ feedback. The receiver sends H-ARQ feedback with an identification of the packet or a sequence number of a packet that the receiver expects to receive next. The receiver stores a packet in a memory before combining the packet with a previously received packet, and decodes the stored packet after failing to decode a combined packet to avoid a corruption error. The receiver may set a timer when sending a NACK. If the receiver fails to receive a packet until expiration of the timer, the receiver initiates a process for recovering the packet. Each H-ARQ feedback may be associated with other attributes. Some H-ARQ processes may operate in an asynchronous mode while others in a synchronous mode in the same direction.

摘要： A method and apparatus for selecting a TFC in a wireless transmit/receive unit (WTRU) is disclosed. The WTRU estimates a transmit power for each of a plurality of available transport format combinations (TFCs). A TFC is selected for an uplink dedicated channel and a TFC is selected for an enhanced uplink (EU) channel. The TFC for the dedicated channel is selected first and independently of the TFC selection of the EU channel. The TFC for the EU channel is selected within a remaining WTRU transmit power after the TFC selection for the dedicated channel.

摘要： A method and apparatus for efficient operation of an enhanced dedicated channel (E-DCH) are disclosed. A physical layer processing includes computation of various control parameters followed by actual processing of the data to be transmitted. In accordance with the present invention, the computation of the control parameters is performed asynchronously from the associated data operation. A medium access control (MAC) layer provides information needed for computation of the control parameters to the physical layer as early as possible, while the data is being processed in parallel. The provided data includes a hybrid automatic repeat request (H-ARQ) profile, a transport block size, power offset, or the like. By sending this data to the physical layer before MAC-e processing is complete, the latency constraint can be significantly relaxed.

摘要： A method and apparatus for processing enhanced uplink scheduling grants are disclosed. A wireless transmit/receive unit (WTRU) detects an absolute grant (AG) and a relative grant (RG). Once the WTRU detects an AG or a RG, a new serving grant (SG) is generated and a hybrid automatic repeat request process may be activated or deactivated depending on whether the received AG is a primary AG or a secondary AG, whether a scheduling mode is a primary AG mode or a secondary AG mode, whether an AG value is set to “INACTIVE” and whether a transmission time interval is 2 ms or 10 ms. A Node-B may send a secondary AG to the WTRU before switching from a primary AG mode to a secondary AG mode and may send the secondary AG only if there is no out-of-date secondary AG exists, which may be detected by implementing a time threshold.
摘要翻译：公开了一种用于处理增强的上行链路调度许可的方法和装置。无线发射/接收单元（WTRU）检测绝对授权（AG）和相对授权（RG）。一旦WTRU检测到AG或RG，则生成新的服务授权（SG），并且可以根据所接收的AG是主AG还是辅助AG来激活或去激活混合自动重传请求过程，无论是调度模式是主AG模式还是辅助AG模式，AG值是否设置为“INACTIVE”，传输时间间隔是2ms还是10ms。节点B可以在从主AG模式切换到辅助AG模式之前向WTRU发送辅助AG，并且只有当没有过期的次级AG存在时才能发送次级AG，这可以通过实现来检测时间阈值。
