Abstract: 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.

Abstract: The present disclosure relates to a communication system for supporting a high data transfer rate. An embodiment of the present disclosure provides a method, performed by a first gNodeB (gNB)-central unit (CU), of supporting an integrated access and backhaul (IAB) node in performing handover to a second gNB-CU in a wireless communication system. The method includes transmitting handover information to at least one lower node connected to the IAB node, the handover information being determined based on a measurement report for handover of the IAB node, transmitting a handover request message including the handover information of the IAB node to the second gNB-CU, receiving context information from the at least one lower node, based on the context information, identifying, as a first class, a lower node to perform intra-CU handover, and identifying, as a second class, a lower node to perform inter-CU handover from among the at least one lower node, supporting intra-CU handover of the lower node identified as the first class, and supporting inter-CU handover of the IAB node to the second gNB-CU, based on the handover information of the IAB node and a handover acceptance message of the IAB node which is received from the second gNB-CU.

Abstract: A random access method may include receiving a random access preamble that is uniquely allocated to a User Equipment (UE) from the UE on an extended-Physical Random Access Channel (e-PRACH) and identifying the UE based on the random access preamble.
