METHOD AND APPARATUS FOR PERFORMING BLIND TRANSPORT FORMAT DETECTION

摘要

Methods and apparatus for performing efficient blind transport format (TF) detection in wireless communication systems are disclosed based on TF groups and efficient hybrid automatic repeat request (HARQ) assisted blind TF detection for retransmissions. When a receiver detects a failure for an initial transmission, a transmitter receives an HARQ negative acknowledgement (NACK) or no feedback from the receiver beyond a certain duration. The transmitter uses the same transport format combination (TFC) for a first retransmission as is used for the initial transmission for data detection, and if the first retransmission fails and after the transmitter gets the HARQ NACK or no feedback from the receiver beyond the certain duration, the transmitter uses a next more robust TFC for a second retransmission and the receiver should also to use next more robust TFC for data detection for the second retransmission from the transmitter. Alternatively, the transmitter uses the next robust TF for the first retransmission.
