APPARATUS AND METHOD FOR ASSIGNING HYBRID-AUTOMATIC REPEAT REQUEST PROCESSES

摘要

PROBLEM TO BE SOLVED: To provide an apparatus and method for assigning automatic repeat request (ARQ)/hybrid-automatic repeat request (H-ARQ) processes (114) in a wireless transmit/receive unit (WTRU) (102) to support enhanced uplink (EU) transmissions.SOLUTION: In a method of the present invention, after parameters associated with the ARQ/H-ARQ processes are configured, the WTRU assigns an ARQ/H-ARQ process for selected data. After transmitting the data, the WTRU determines whether feedback information for the data has been received. The WTRU releases the ARQ/H-ARQ process if an acknowledgement (ACK) message has been received, and retransmits the data if a non-acknowledgement (NACK) message or no feedback information has been received in a predetermined time period while incrementing a transmission counter (118) in the WTRU.
