    Abstract: A communication transmitter retransmits a Medium Access Control (MAC) Protocol Data unit (MPDU) to a communication receiver over a communication channel using a Hybrid Automatic Repeat reQuest (HARQ) retransmission scheme. The MPDU includes a plurality of information bits. The communication transmitter includes 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.

    Abstract: A device resolves a collision between its transmission and a simultaneous transmission of another device. The device is configured to interrupt its transmission, determine a negotiation signal, and determine at least one available resource to occupy with the negotiation signal during a negotiation period. Further, the device is configured to transmit the negotiation signal on the at least one available resource and simultaneously receive a negotiation signal on another resource from at least one other device during the negotiation period. Then, the device is configured to decide, based on all negotiation signals, whether to retransmit the interrupted transmission after the negotiation period.

    Abstract: This application provides a communication method and apparatus, and relates to the communication field. The method includes: generating a physical layer protocol data unit PPDU, where the PPDU includes a first field indicating that the PPDU is an extremely high throughput sounding null data packet EHT sounding NDP transmitted based on orthogonal frequency division multiple access OFDMA, the PPDU further includes an extremely high throughput-long training field EHT-LTF and a packet extension PE field, and the PE field is adjacent to the EHT-LTF; and sending the PPDU. In this way, a Bfee may determine, based on the first field in the PPDU, that the PPDU is the EHT sounding NDP transmitted based on OFDMA, perform channel estimation by using the PPDU, and feed back channel state information to a Bfer, to implement functions such as beamforming and resource scheduling for OFDMA transmission, thereby improving channel quality and a throughput.

    Abstract: This application discloses a retransmitted data sending method, a retransmitted data receiving method, and a related apparatus, and relates to the field of communications technologies. In this solution, a transmit end generates a retransmitted codeword based on information bits of each codeword corresponding to an incorrect MPDU, where the retransmitted codeword includes a codeword having some of information bits included in the incorrect MPDU. For the codeword having some of information bits included in the incorrect MPDU, the transmit end punctures a correctly received information bit in the codeword, and then sends the information bit. In this way, a receive end may directly perform combined decoding or joint decoding on an LLR of a codeword of a retransmitted MPDU and an LLR of a codeword of an MPDU that is incorrectly received last time. This improves transmission efficiency and transmission reliability.
