摘要： A communication method and apparatus for communicating with an intelligent base station in a wireless communication system are provided. An operation method of the intelligent base station includes determining whether reconfiguration of an intelligent base station group that supports a terminal is necessary, according to movement information of the terminal, the determination being performed by a first intelligent base station included in the intelligent base station group, when the first intelligent base station determines that reconfiguration of the intelligent base station group is necessary, transmitting a join request to join the intelligent base station group, to a nearby intelligent base station not included in the intelligent base station group, receiving a join approval message in response to the transmitted join request, and reconfiguring the intelligent base station group, based on the received join approval message.

摘要： A method by a first base station comprises receiving a message including information related to a sum of traffic loads of user equipment and information related to a location of a second base station from second base stations, identifying a sum of traffic loads transmitted from the second base stations, to the UEs, identifying whether the identified sum of the traffic loads is larger than a sum of data rates for the corresponding UEs of the corresponding second base stations located in the specific first area, when the identified sum of the traffic loads is larger than the sum of the data rates, identifying a specific UE to be operated as a second base station among the corresponding UEs located in the specific first area, and transmitting information indicating that the specific UE is to operate as the second base station to the specific UE.
