Description

Communication method and related device Technical Field The present application relates to the field of communications technologies, and in particular, to a communications method and a related device. Background In the communication system, when a plurality of sensing nodes exist, the sensing can be performed by combining the plurality of sensing nodes so as to improve the sensing precision. At present, for a sensing area, a plurality of sensing nodes sense to obtain corresponding sensing data. And then the sensing network element averages the sensing data of the sensing nodes to obtain combined sensing data, and the sensing of the sensing area is realized through the combined sensing data. However, the perceived resolution of different sensing nodes is different, in other words, the perceived capability of different sensing nodes is different. Since the perceived data has noise, each perceived data has a corresponding signal-to-noise ratio. And the signal-to-noise ratio of the sensing data is related to the transmit power at which the sensing node transmits the sensing signal. Therefore, how to configure the transmission power of the sensing signal to improve the sensing performance for the sensing nodes with different sensing capabilities is a considerable problem.
