摘要： This provides a spatial multiplexing method and apparatus, to introduce WLAN sensing into a conventional spatial multiplexing mechanism and improve communication efficiency. The method includes: An AP sends a first request message to a first station and a second station, to request to measure channel quality in one or more sensing beam directions in a first SP; the AP sends a second request message to a third station and a fourth station, to request to measure channel quality in a communications beam direction in a second SP; the first station, the second station, the third station, and the fourth station separately perform measurement and report respective first measurement results; and the AP receives the first measurement results of the stations, and determines, based on the first measurement results, whether to perform spatial multiplexing on the first SP and the second SP.
