Systems and methods for Wi-Fi sensing are provided. A method for Wi-Fi sensing carried out by a sensing receiver is described. A hybrid sensing-data trigger is created. The hybrid sensing-data trigger includes resource allocation fields corresponding to each of first sensing channel resource allocation to first sensing transmitter, second sensing channel resource allocation to second sensing transmitter, first data channel resource allocation to first station, and second data channel resource allocation to second station. The hybrid sensing-data trigger is transmitted to first sensing transmitter, second sensing transmitter, first station, and second station. Subsequently, first sensing transmission is received from first sensing transmitter, second sensing transmission is received from second sensing transmitter, first data transmission is received from first station, and second data transmission is received from second station. A first sensing measurement is generated based on first sensing transmission and second sensing measurement is generated based on second sensing transmission.
