(4) After receiving the second prior information request, the devices in the candidate sensing link set feed back the second prior information to Sensing MF. Specifically, it may be that the second a priori information request sent by Sensing MF is a request to obtain the current status or capability information of the second device and/or the third device, and the second device and/or the third device that receives the request are interested in the current Report status or capability information;

Alternatively, the second prior information request sent by the Sensing MF is a request to obtain feedback from the second device and/or the third device that agrees or refuses to participate in the sensing measurement. The second device and/or the third device that receives the request are based on the current status or Ability information determines whether to participate in perceptual measurement and provide feedback.

Optionally, determine the sensing signal configuration and/or measurement volume according to the link characteristics. For example, link 1 supports larger bandwidth, and priority is given to delay/distance measurement volume. Link 2 supports longer time domain duration, and priority is given. To allocate Doppler/velocity measurement quantities, link 3 supports a larger receiving antenna array aperture and assigns angle measurement quantities first; for example, link 1 is spontaneous self-receiving, link 2 is A transmitting and B receiving, and link 1 is given priority.
