Abstract:
1. A method for assigning a hybrid-automatic repeat request (H-ARQ) process in a wireless transmit/receive unit (WTRU) for supporting enhanced uplink (EU) data transmission, the method comprising: receiving configuration parameters for a plurality of medium access control for dedicated channel (MAC-d) flows, wherein the configuration parameters include a priority associated with each MAC-d flow and a maximum number of H-ARQ transmissions associated with each MAC-d flow; selecting data for transmission over an enhanced dedicated channel (E-DCH) based on a priority associated with at least one of the plurality of MAC-d flows, wherein data of at least one of the plurality of MAC-d flows associated with a highest priority that has data available for transmission is selected; on a condition that the selected data is new data that was not previously transmitted, assigning an available H-ARQ process for supporting transmission of the selected data, and transmitting the selected data over the E-DCH using the assigned H-ARQ process; on a condition that the selected data was previously transmitted, transmitting the selected data over the E-DCH using the same H-ARQ process that was assigned to previously transmit the selected data; incrementing a transmission count in response to transmitting the selected data; determining whether the transmission count is at least equal to a maximum number of H-ARQ transmissions associated with one of the plurality of MAC-d flows from which the data for transmission was selected; and discarding the selected data in response to a determination that the transmission count is at least equal to a maximum number of H-ARQ transmissions associated with one of the plurality of MAC-d flows from which the data for transmission was selected.
