METHOD AND APPARATUS FOR ASSIGNING HYBRID-AUTOMATIC REPEAT REQUEST PROCESSES |
摘要 |
A method and apparatus for assigning a hybrid-automatic repeat request (H-ARQ) process in a wireless transmit/receive unit (WTRU) to support enhanced uplink (EU) data transmission. Configuration parameters for enhanced uplink (EU) operation are received. The configuration parameters include a priority associated with a medium access control for dedicated channel (MAC-d) flow and a maximum number of H-ARQ transmissions associated with the MAC-d flow. Data is selected for transmission over an enhanced dedicated channel (E-DCH) based on a priority of the MAC-d flow, wherein data with the highest priority is selected. On a condition that the selected data is new data that was not previously transmitted, an available H-ARQ process is assigned for supporting transmission of the selected data, and the selected data is transmitted over the E-DCH using the assigned H-ARQ process. On a condition that the selected data was previously transmitted, the selected data is retransmitted over the E-DCH using the same H-ARQ process that was assigned to previously transmit the selected data. A transmission count is incremented in response to transmitting or retransmitting the selected data. A determination is made of whether the transmission count is at least equal to the maximum number of H-ARQ transmissions. The selected data is discarded in response to a determination that the transmission count is at least equal to the maximum number of H-ARQ transmissions. |
