Abstract:
1. A method for handover of a serving enhanced Node B (eNB) in a wireless communication system, the method comprising: receiving, from at least one adjacent eNB, interference power information of an uplink (UL) signal and interference variation information indicating that an interference of the UL signal is increased or decreased; selecting an adjacent eNB, for which the received interference power information indicates that interference power of the UL signal is equal to or greater than a threshold value, as a target eNB for a User Equipment (UE) among the at least one adjacent eNB; determining whether an interference of the target eNB is increased based on the interference variation information received from the target eNB; if the interference of the target eNB is increased, determining that the handover of the UE is delayed; and transmitting a handover parameter to the UE to perform handover to the target eNB; wherein the interference of the target eNB is an interference generated by a UL signal of the UE.
