Abstract: The present disclosure relates to methods and apparatuses for determining transmit power in a wireless local area network. In an example method, a station receives a trigger frame, where the trigger frame indicates a first resource unit allocated to the station. The trigger frame includes an access point (AP) transmit power subfield and an uplink target receive power subfield. The station sends a trigger-based physical layer protocol data unit (TB PPDU) at first transmit power. The TB PPDU occupies a second resource unit included in the first resource unit. The first transmit power is determined based on an indication of the AP transmit power subfield, an indication of the uplink target receive power subfield, the second resource unit, and the first resource unit.

Abstract: A cyclic shift diversity-based communication method and apparatus. A maximum number of antennas supported in this method is greater than 8. A cyclic shift is performed on a first preamble part of each antenna by using a cyclic shift diversity value, so that an automatic gain control error is reduced in response to the use of more antennas (for example, 16 antennas).

Abstract: Embodiments of this disclosure include a channel access method in a wireless local area network (WLAN) and related apparatus. In the method, a communication device receives a first overlapping basic service set (OBSS) frame on a primary channel, determines a first channel with a busy channel state based on bandwidth information carried in the first OBSS frame, and performs channel contention when switching from the primary channel to a second channel. After the communication device backs off to 0 on the second channel, the communication device determines a third channel used for transmitting data, where the third channel does not include any sub-channel of the first channel, and the first channel includes the primary channel.
