Description

Communication method and communication device Technical Field The present application relates to the field of wireless, and more particularly, to a communication method and a communication apparatus. Background Wireless local area networks (wireless local area network, WLAN) have evolved to date, 802.11 being one of the currently prevailing wireless access standards, and have gained extremely wide commercial use for over a decade. Among them, 802.11bf is a new generation of wireless standards for WLAN awareness (WLAN SENSING). WLAN awareness is the property of a WLAN-aware device to determine a predetermined target (e.g., object, animal, person, etc.) in a given environment based on received wireless signals, including the distance, bearing, speed, motion, behavior, etc. of the target. In an SR2SR flow under a Sensing By Proxy (SBP) Sensing flow or a Sensing by Proxy (Sensing responder to Sensing responder, SR2 SR) Sensing flow, after an Access Point (AP) helps a Station (STA) to establish an SR2SR Sensing task, the AP participates in each subsequent Sensing measurement exchange process, so that the AP consumes more energy. Disclosure of Invention The application provides a communication method and a communication device, which enable an STA to realize SR2SR sensing measurement under the condition that an AP does not participate or the AP does not participate, thereby being beneficial to reducing the energy consumption of the AP. In a first aspect, a method of communication is provided. The method may be performed by the first device, or may be performed by a chip or a circuit in the first device, which is not limited in this regard. For convenience of description, the following description will be given with the first device execution example. The method comprises the steps of sending a first frame to second equipment, wherein the first frame comprises first information and at least one piece of information of third equipment, the first information is used for indicating the second equipment to trigger first perception measurement, the information of the third equipment comprises address information and role information of the third equipment, the role information of the third equipment is used for indicating the third equipment to the second equipment to be a perception sending end and/or a perception receiving end, one or more pieces of third equipment in the second equipment and the at least one piece of third equipment participate in the first perception measurement, receiving the second frame from the second equipment, and the second frame is a response frame of the first frame. Based on the technical scheme, the first device can instruct the second device to trigger the first perception measurement and send the information of at least one third device possibly participating in the first perception measurement to the second device, so that in the perception measurement exchange stage of the first perception measurement, the second device can control the transceiving operation of the third device according to the information of the third device participating in the first perception measurement. In the case where the transceiving operation of the third device participating in the first perception measurement is controlled by the second device, the first device may not participate in the perception measurement exchange phase of the first perception measurement, so that the energy consumption of the first device may be reduced. Wherein the second device triggering the first sensing measurement refers to a sensing measurement exchange phase in which the second device triggers the first sensing measurement. With reference to the first aspect, in certain implementations of the first aspect, the first frame further includes second information, the second information being used to indicate that the first perceptual measurement is performed on a first channel, the first channel being an off-channel. Based on the technical scheme, the second device and the third device perform the first perception measurement on the off-channel, so that bandwidth resources of the basic channel can be saved, and the first device is beneficial to performing other tasks different from the first perception measurement on the basic channel. With reference to the first aspect, in some implementations of the first aspect, the first frame further includes third information, where the third information is used to indicate a reception mode of the measurement report of the first sensing measurement, the reception mode is one of a second device receiving the measurement report in a Multi User (MU) manner, the second device receiving the measurement report in a Single User (SU) manner, or the first device receiving the measurement report in a MU manner. With reference to the first aspect, in certain implementations of the first aspect, the information of the third device further includes measurement report request information, the measuremen
