Abstract: This application provides methods and apparatus for sending feedback information. By binding a BAR-BA feedback manner, that is, first a request and then a feedback, when it is determined that data retransmission is performed by using a hybrid automatic repeat request (HARQ) mechanism, duration of an acknowledgment operation performed by a data receive end on retransmitted data may be increased. Alternatively, the receive end estimates duration required for feeding back a receiving status of the retransmitted data, and feeds back the duration to a transmit end. The transmit end may therefore adaptively adjust duration of the retransmitted data based on a feedback capability of the receive end, to ensure that the feedback of the receive end on the receiving status of the retransmitted data is within a short inter-frame space (SIFS).

Abstract: An antenna channel sounding method, an apparatus, and a storage medium are provided. A first communication apparatus sends a first frame and a first physical layer protocol data unit (PPDU) to a second communication apparatus. The first frame includes first indication information for indicating the second communication apparatus to perform transmit antenna channel sounding. The first PPDU is a null data packet (NDP). The first PPDU includes a first identifier field indicating an identifier of a first transmit antenna set. In this way, the second communication apparatus can determine a correspondence between a transmit antenna channel sounding result corresponding to a received PPDU and an identifier of a transmit antenna set, and can determine an identifier of a transmit antenna set selected based on one or more transmit antenna channel sounding results. This can perform antenna selection based on the antenna channel sounding results in the large-scale antenna scenario.

Abstract: A terminal device receives first indication information, where the first indication information indicates the first configuration information of a first signal, and the first configuration information at least includes information about a first resource and a first antenna port number. The terminal device receives the first signal on the first resource and receives a second signal on a second resource, where a second antenna port number corresponding to the second signal is different from the first antenna port number, and the first resource and the second resource overlap. The terminal device determines information in the second signal based on the first signal. In a possible design, the terminal device may determine, based on the first configuration information sent by a network device, a signal sequence carried by the first signal.
