Abstract:
The present disclosure provides a channel measurement method and a STA to ensure that a sub-channel on which channel measurement is performed is idle, thereby preventing, to some extent, transmission in an OBSS from being affected by UL channel measurement. The method includes: receiving, by a station STA, a measurement notification message sent by an access point AP, where the measurement notification message carries identifier information of a channel that needs to be measured; and sending, by the STA, a sounding reference signal by using M idle sub-channels, so that the AP measures the M idle sub-channels according to the received sounding reference signal, where the M idle sub-channels are M idle sub-channels determined by the STA from at least one sub-channel included in a channel indicated in the identifier information of the channel that needs to be measured, and M is an integer greater than or equal to 1.

Claim (Index 6):
The method according to  claim 5 , wherein before sending, by the STA, a sounding reference signal by using M idle sub-channels, the method further comprises:\n determining, by the STA according to the LTF quantity indication field carried in the measurement notification message, the STA queue, and the moment at which the STA receives the measurement notification message, a last STA that sends a sounding reference signal, and a third moment at which sending of the sounding reference signal by the last STA that sends the sounding reference signal ends, wherein the last STA that sends the sounding reference signal is a preceding STA that is in the STA queue and that is adjacent to the STA; and performing, by the STA, CCA in a time interval between the third moment and the second moment, and determining M sub-channels whose CCA results are idle as the M idle sub-channels.
