Abstract: Embodiments of this application provide a channel sounding method and apparatus, and relate to the communication field. The method includes: A station STA receives channel sounding frames sent by a plurality of access points APs; the STA performs channel sounding based on the channel sounding frames to obtain channel state information of each AP; and the STA sends a channel measurement report frame, where the channel measurement report frame includes channel state information of some of the plurality of APs and identifiers of the some APs, and the channel measurement report frame is further used to indicate that the some APs are selected to participate in coordinated transmission. That the channel measurement report frame is used to indicate that an AP is selected to participate in coordinated transmission can not only feedback channel state information but also reduce signaling overheads.

Abstract: Embodiments of the present disclosure disclose example full-duplex data transmission methods and an example full-duplex data transmission apparatus. One example method includes: A first signal is sent by an access point to at least one first station. Information used to indicate at least one full-duplex TXOP is included in the first signal. A first data frame to the first station is sent by the access point based on the first signal. A second data frame is received by the access point from at least one second station. Transmission time intervals of the first data frame and the second data frame are included in a same full-duplex TXOP among the at least one full-duplex TXOP, and the transmission time intervals of the first data frame and the second data frame have a nonempty intersection set.

Abstract: Embodiments of the present disclosure relate to a multi-channel access method and apparatus. A first device performs data transmission with a second device on a first reserved channel, and the method includes: identifying, by the first device, whether a non-reserved channel except the first reserved channel is in an idle state; triggering, by the first device, a backoff procedure when the non-reserved channel is in the idle state; sending, by the first device, a channel reservation frame on the non-reserved channel after the backoff procedure ends, where the channel reservation frame is used to enable the first device to use the non-reserved channel as a second reserved channel; and performing, by the first device, data transmission with the second device on the first reserved channel and the second reserved channel.

Abstract: The present invention discloses an access point, a station, and a beacon frame sending method and system, relates to the communications field, and resolves a problem of relatively large network overheads caused for purposes of ensuring that in a WLAN system having multiple channels, a STA can quickly access a network. A specific solution is as follows: A first sending unit sends a beacon indication frame on each subchannel of N subchannels, where the beacon indication frame is used to indicate configuration information of a beacon frame; and a second sending unit sends the beacon frame on at least one first subchannel. The present invention is applied to a beacon frame sending process.
