A method for sensing sneezing based on a wireless signal includes obtaining a wireless signal, where the wireless signal propagates in space including a first object. Doppler estimation is performed on the wireless signal, to obtain Doppler information of the wireless signal. The Doppler information of the wireless signal may be used for indicating impact of the first object on a frequency of the wireless signal. Whether the first object is sneeze droplets is determined based on the Doppler information of the wireless signal.

Method for sensing sneezing based on wireless signal, and related apparatus

A wireless local area network sensing method. The method includes: in a process in which a second network device performs high frequency MIMO channel access, a first network device sends indication information to a plurality of second network devices, where the indication information indicates the plurality of second network devices to send uplink sensing signals; and the first network device receives the uplink sensing signals from the second network devices and performs uplink sensing based on the uplink sensing signals.

Wireless local area network sensing method, network device, and chip

This application discloses a signal processing method and an apparatus. The method includes: A transmit device generates a PPDU, and sends the PPDU; and a receive device receives the PPDU, and processes M sequences carried in the PPDU. The PPDU shown in this application includes a first field, the first field is used for carrying M sequences, the M sequences correspond to M space-time streams, one sequence corresponds to one space-time stream, and M is a positive integer. According to the method provided in this application, sequence sending efficiency can be effectively improved.

Signal processing method and apparatus

A spatial multiplexing method and apparatus are provided to introduce WLAN sensing into a conventional spatial multiplexing mechanism and improve communication efficiency. In the method 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.
