CN-122029846-A - Apparatus and method for communication

Abstract

Embodiments of the present disclosure provide a solution for sensing and communication. In a solution, a network device receives a request for a sensing service from a core network device. In response to a request for a sensing service, the network device performs at least a portion of the sensing function with at least one sensing device associated with the sensing service based on the sensing capabilities of the at least one sensing device. The sensing functions comprise sensing capability exchange, sensing mode selection, sensing resource determination, sensing result processing and sensing result opening. In this way, the sensing function is divided between the Core Network (CN) and the Random Access Network (RAN), and thus the local sensing function can be implemented at the RAN, thereby reducing the interaction delay between the CN and the RAN and improving the sensing performance of the sensing service in the network system.
