A METHOD AND APPARATUS FOR ASSIGNING AUTOMATIC REPEAT REQUEST (ARQ)/HYBRID-AUTOMATIC REPEAT REQUEST (H-ARQ) PROCESSES IN A WIRELESS TRANSMIT/RECEIVE UNIT (WTRU) TO SUPPORT ENHANCED UPLINK (EU) DATA TRANSMISSIONS. 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 IN THE WTRU. WHEN AN ARQ/H-ARQ TRANSMISSION LIMIT HAS BEEN REACHED, THE WTRU MAY DISCARD THE DATA OR REINITIATE THE TRANSMISSION. AN ARQ/H-ARQ PROCESS ASSIGNED FOR TRANSMISSION OF LOWER PRIORITY DATA MAY BE PREEMPTED FOR TRANSMISSION OF HIGHER PRIORITY DATA WHEN THERE IS NO AVAILABLE ARQ/H-ARQ PROCESS. |
