AI summary
Provided are communication methods and communication devices. A communication method comprises: a first device receiving one or a plurality of sensing signals, said sensing signal being a reference signal and/or a signal carried in a data channel. On the basis of the present application, a reference signal and/or a signal carried in a data channel in a wireless communication system can be multiplexed for sensing. Therefore, sensing can be implemented without defining a new signal or channel, thus reducing a standardized workload of integrated sensing and communication as well as the system complexity and the system overhead. In addition, with regard to a reference signal, the bandwidth of the reference signal can be relatively large, so that multiplexing the reference signal for sensing at least can implement sensing at relatively high precision; with regard to a signal carried in a data channel, the signal is a signal usually required to be sent during a communication process, so that multiplexing the signal in the data channel for sensing at least can reduce the overhead of the sensing.
