Abstract:
1. A method for transmitting enhanced uplink (EU) data, implemented by a wireless transmit/receive unit (WTRU), the method comprising: receiving configuration parameters for EU operation, wherein the configuration parameters include a priority associated with each configured medium access control for dedicated channel (MAC-d) flow and a maximum number of hybrid automatic repeat request (H-ARQ) transmissions associated with each configured MAC-d flow; identifying a H-ARQ process to use for transmission for a next transmission time interval (TTI); determining whether the identified H-ARQ process is available for new data for the next TTI; on a condition that the identified H-ARQ process is available for new data for the next TTI, selecting data for transmission over an EU channel based on the priority associated with the configured MAC-d flows, setting a transmission status to indicate a new transmission, and transmitting the selected data using the identified H-ARQ process; and on a condition that the identified H-ARQ process is not available for new data for the next TTI, setting the transmission status to indicate a retransmission, and retransmitting data associated with the identified H-ARQ process; wherein the retransmitting is limited to the maximum number of H-ARQ transmissions associated with a MAC-d flow from which the data for transmission was selected.
