AUTOMATIC REPEAT REQUEST (ARQ) PROTOCOL EMPLOYING FIRST INFORMATION INDICATING WHETHER TO PERFORM RETRANSMISSION OF AN UPLINK DATA PACKET AND SECOND INFORMATION INDICATING A TRANSPORT FORMAT FOR THE RETRANSMISSION
A transmission apparatus controls a transport format for retransmission of data packets transmitted uplink to a receiving apparatus via at least one data channel using an automatic repeat request (ARQ) protocol. A transmitter transmits an uplink data packet via the data channel to the receiving apparatus, and a receiver receives first information along with second information from the receiving apparatus. The first information is used for determination whether to perform a retransmission of the uplink data packet at the transmission apparatus, and the second information indicates a transport format for the retransmission. The transmitter transmits the retransmission from the transmission apparatus to the receiving apparatus according to the transport format indicated in the second information element using a transmission timing based on the ARQ protocol.
