Abstract: This application provides a communication method and an apparatus, to implement a channel sensing procedure between different apparatuses while meeting a communication requirement, thereby improving communication efficiency of a WLAN system and reducing overheads. In the method, a first apparatus sends a first frame to a second apparatus, where the first frame is used to request channel sensing; and the first apparatus receives a second frame from the second apparatus, where the second frame includes channel sensing information between the first apparatus and the second apparatus, the channel sensing information is determined based on a part of or all of n PPDUs, the n PPDUs are PPDUs sent by the first apparatus, and n is greater than or equal to 1.

Abstract: Embodiments of this application relate to the communications field, and in particular, to an information indication method and apparatus in the communications field. The embodiments of this application include: generating a PPDU including radar indication information, where the radar indication information is used to indicate that the PPDU is a PPDU used for radar testing, and transmitting the PPDU. According to the method provided in the embodiments of this application, the transmit end explicitly indicates that the PPDU is a PPDU used for radar testing rather than a PPDU used for communication between communications devices. When a receive end receives the PPDU, the receive end no longer monitors a channel, thereby reducing power consumption of the receive end.

Abstract: A method for assisting in locating a target object, a method for locating a target object, and an apparatus. In an embodiment, the method for assisting in locating a target object is applied to a station (STA), and the method includes: receiving a wireless sensing sounding frame including radar measurement indication information from an access point (AP); sending an uplink data packet to the AP, recording a first sending moment, and performing radar measurement on a target object based on the radar measurement indication information to obtain a radar measurement result; receiving a downlink data packet from the AP, and recording a first receiving moment; and sending the first sending moment, the first receiving moment and the radar measurement result to the AP.
