Abstract: The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. Disclosed are a method and an apparatus for a congestion control in wireless communication, the method includes: a network side node receives a congestion related information reported by a UE or UEs, determines a congestion control range or congestion control ranges based on the congestion related information reported by the UE or UEs and transmits determined congestion control range information to a UE or UEs; the UE or UEs receives the congestion control range information transmitted by the network side node, determines whether the UE or UEs is/are within the congestion control range according to the received congestion control range information, and performs the congestion control when the UE or UEs is/are within the congestion control range. The congestion related information is reported to the network side through the UE or UEs such that the network side can more accurately grasp the global congestion situation, thus facilitating the formulation of more optimized congestion control strategy and meanwhile reducing information exchange between the UEs, reducing the resource consumption of the PC5 interface, and reducing the possibility of the occurrence of the congestion.
