COMMUNICATION TRANSMITTER FOR RETRANSMITTING MAC PROTOCOL DATA UNIT (MPDU)

The invention relates to a communication transmitter for retransmitting an MPDU to a communication receiver over a communication channel using an HARQ retransmission scheme. The MPDU comprises a plurality of information bits. The communication transmitter (100) comprises a processor configured to determine the MPDU to be retransmitted based on a Block ACK frame received from the communication receiver, the Block ACK frame indicating previously correctly decoded MPDUs at the communication receiver, and to generate a bit sequence to be transmitted to the communication receiver, wherein the bit sequence comprises the plurality of information bits. The communication transmitter further comprises a communication interface configured to transmit the bit sequence to the communication receiver for retransmitting the MPDU to the communication receiver. The invention also relates to a communication receiver for receiving such retransmitted MPDU using the HARQ retransmission scheme. 本发明涉及用于使用HARQ重传方案通过通信信道向通信接收器重传MPDU的通
