In order to solve the problem that the prior art communication system cannot flexibly provide a proper air interface technology for a communication service, which results in low utilization efficiency of wireless resources, an embodiment of the present invention provides a solution based on the communication system shown in fig. 1, so as to improve the utilization efficiency of resources in the communication system. As shown in fig. 1, an embodiment of the present invention provides a communication system 100. The communication system 100 includes at least one Base Station (BS) and a plurality of UEs. The plurality of UEs in the communication system 100 includes at least one UE that may be used for cellular communication. Cellular communication refers to communication between a UE and a base station. A UE performing cellular communication has a function of performing cellular communication with a base station, and may also be referred to as a cellular UE or a cellular terminal.

For example, in FIG. 1, a plurality of UEs may be respectively identified as UEs 40A-40E, a plurality of base stations may be respectively identified as BS20, BS22, and BS24, cellular communications may be performed between the UEs 40A-40E and the base stations 20-24, respectively, and cellular links may exist between the UEs 40A-40E and the base stations 20-24, respectively.

In the solution of this embodiment, as in the communication system 100 shown in fig. 1, the UEs may be under the coverage of different base stations, and the UEs may be served by different base stations. For example, UE40A and UE40B are located under base station 22 coverage, UE40B, UE40C and UE40E are located under base station 20 coverage, UE40D and UE40E are located under base station 24 coverage, UE40A, UE40C and UE40D are served by base station 22, base station 20 and base station 24, respectively; UE40B is served by base station 22 and base station 20; UE40E is served by base station 20 and base station 24.

Or, a plurality of base stations can exchange information with each other, one of the base stations is used as a control node for controlling, and the base station used as the control node can perform uniform resource scheduling and management and the like according to information sent by other base stations and information obtained and maintained by the base station.
