Sensing method and communication device Cross-reference regarding related applications This application claims priority to Chinese patent application No. 202311194782.2, filed with the China National Intellectual Property Administration on September 14, 2023, with the title of the invention "SENSING METHOD AND COMMUNICATION APPARATUS", the entirety of which is incorporated by reference into this specification. Technology field This application relates to the field of wireless local area network (WLAN) technologies, and in particular, to a sensing method and a communication device. In everyday life, signals transmitted by wireless fidelity (Wi-Fi) devices are typically received after being reflected, diffracted, and scattered by various obstacles. Through the analysis of wireless signals, such as channel state information (CSI) affected by various obstacles, the surrounding environment can be inferred and sensed, thereby leading to the development of wireless local area network (WLAN) sensing technology. In the IEEE (Institute of Electrical and Electronics Engineers) 802.11 series standards, sensing is handled as a session. For example, a sensing initiator may transmit a sensing measurement request frame to request a related device (such as a sensing responder) to join a sensing measurement session; and a sensing responder may transmit a sensing measurement response frame to respond to the sensing measurement session transmitted by the sensing initiator. After the sensing measurement session is established, the sensing initiator and the sensing responder enter a sensing measurement exchange phase to perform the sensing measurement. When there is no need for the sensing measurement to continue, the sensing initiator or the sensing responder may consider terminating the established sensing measurement session. In current standards, for example, IEEE 802.11bf, the design of a solution to join the next sensing measurement session after the previous one has ended is not sufficiently flexible. The embodiments of the present application provide a sensing method and a communication device that optimize the time interaction problem at the end of a sensing measurement session, thereby making the time for a sensing initiator or a sensing responder to participate in the next sensing measurement session more flexible after the end of a sensing measurement session.
