  • Patent number: 12289693
    Abstract: Embodiments of this disclosure disclose a multi-link communication method and a related apparatus. In a scenario in which simultaneous transmission and reception over a plurality of links is not supported, a multi-link device first sends a first physical layer protocol data unit (PPDU) over a first link, and then sends a second PPDU over a second link through channel contention, where an end time of the second PPDU is not later than an end time of the first PPDU. The method not only ensures fairness of multi-link access, but also can reduce an idle rate of the plurality of links.

  • Patent number: 12267163
    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.

  • Publication number: 20250097820
    Abstract: A data transmission method and apparatus, and relates to the communication field. In the method, after obtaining a path parameter of each of at least one communication path between a first device and a second device, the first device may demodulate first data based on a pilot and the path parameter of each communication path. In other words, when demodulating the first data, the first device may refer to not only the pilot but also the path parameter of each communication path. The path parameter of each communication path can assist in demodulating the first data. When the path parameter of each communication path assists in demodulating the first data, there may be no need for too many pilots. Therefore, a resource occupied by the pilot can be reduced.
