METHOD AND SYSTEM FOR SUPPORTING MULTIPLE HYBRID AUTOMATIC REPEAT REQUEST PROCESSES PER TRANSMISSION TIME INTERVAL

摘要

A method and apparatus may be used for supporting multiple hybrid automatic repeat request (H-ARQ) processes per transmission time interval (TTI). A transmitter and a receiver may include a plurality of H-ARQ processes. Each H-ARQ process may transmit and receive one TB per TTI. The transmitter may generate a plurality of TBs and assign each TB to a H-ARQ process. The transmitter may send control information for each TB, which may include H-ARQ information associated TBs with the TBs. The transmitter may send the TBs using the associated H-ARQ processes simultaneously per TTI. After receiving the TBs, the receiver may send feedback for each of the H-ARQ processes and associated TBs indicating successful or unsuccessful receipt of each of the TBs to the transmitter. The feedback for multiple TBs may be combined for the simultaneously transmitted H-ARQ processes, (i.e., TBs).

主权项

1. A wireless transmit/receive unit (WTRU) for receiving multiple transport blocks (TB)s, the WTRU comprising:
a receiver configured to, in one TTI, receive control information for each of a plurality of TBs, and to utilize the control information to receive the plurality of TBs; a processor configured to process the plurality of TBs, to generate a feedback message that includes a channel quality indicator (CQI) and indicates successful or unsuccessful receipt of each of the plurality of TBs, to determine whether to include a cyclic redundancy check (CRC) with the feedback message, and based on the amount of feedback, to select a coding scheme for the feedback message; and a transmitter configured to transmit the generated feedback message.
