Patent ID: 7647541

Claim:
A wireless transmit/receive unit (WTRU) configured to assign a plurality of hybrid automatic repeat request (H-ARQ) processes, comprising: a receiver configured to receive configuration parameters for enhanced uplink (EU) operation, wherein the configuration parameters include a priority and a maximum number of HARQ transmissions associated with a medium access control for dedicated channel (MAC-d) flow; a pool of H-ARQ processes configured to support transmission of EU data; a transmission counter configured to indicate a number of transmissions associated with an assigned H-ARQ process; a controller configured to select data for transmission over an enhanced dedicated channel (E-DCH), based on the priority of the MAC-d flow, by a medium access control for enhanced dedicated channel (MAC-e), and assign an available H-ARQ process configured to support transmission of the selected data; and a transmitter configured to transmit the selected data using the assigned H-ARQ process, wherein: on a condition that the selected data was previously transmitted the transmitter is configured to retransmit the selected data using the same H-ARQ process that was used to previously transmit the selected data; and on a condition that the selected data is new data that was not previously transmitted and there is a HARQ process available, the controller is configured to assign an available H-ARQ process for supporting transmission of the selected data.
