Communication method, access point, and station

A station, comprising:

• a first sending unit configured to send a first channel quality measurement report to an access point (AP), wherein the first channel quality measurement report indicates a channel noise value measured during a first time period by the station in a second antenna mode when a third station and a fourth station communicate with each other in a first antenna mode;
• and
• a first receiving unit configured to receive an grant frame from the AP in response to the first channel quality measurement report sent by the first sending unit, wherein the grant frame includes first instruction information and/or second instruction information, the first instruction information is used to instruct the station and the second station to measure channel noise values in an antenna mode other than the second antenna mode, and the second instruction information is used to instruct the station and the second station to communicate with each other in an antenna mode other than the second antenna mode, so that the third station and the fourth station measure channel noise values.
