Abstract:
Embodiments of the present disclosure provide example congestion control methods, base stations, and user equipment. After determining that congestion control needs to be performed, a base station determines a congestion control policy, and determines, from UE in coverage of the base station, first UE that needs to perform adjustment according to the congestion control policy. The base station can then send the congestion control policy to the first UE, so that the first UE performs adjustment, to alleviate a congestion status of a PC5 interface. In this process, the base station performs centralized control on all UE in the coverage of the base station.
