CHANNEL MEASUREMENT METHOD AND STA
First Claim
1. A channel measurement method, comprising:
- receiving, by a station (STA), a measurement notification message sent by an access point (AP), wherein 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, wherein the M idle sub-channels are determined by the STA from 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.

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.

20. A station (STA), comprising a communications interface and a processor, wherein:
-
the processor is configured to receive, by using the communications interface, 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 the processor is further configured to send a sounding reference signal by using the communications interface and 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 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. - View Dependent Claims (21)
