Abstract: A base station receives an uplink data packet from a user equipment based on a synchronous hybrid automatic repeat request (HARQ) protocol, and transmits a first information element and a second information element in parallel to the user equipment. The first information element indicates whether to perform a retransmission of the uplink data packet, and the second information element indicates modulation and coding scheme (MCS) for the retransmission. The base station receives the retransmission from the user equipment according to the modulation and coding scheme. The first information element is for example an ACK/NACK feedback message.

Abstract: 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.
