METHOD AND APPARATUS FOR PERFORMING FAST LINK ADAPTATION BASED ON SOUNDING REFERENCE SIGNAL IN WIRELESS COMMUNICATION SYSTEM

A method of performing fast link adaptation through sounding reference signal (SRS) overhearing when handover is required as a user equipment (UE) is moved in a wireless communication system. The method includes transmitting, to a UE served by a first BS, configuration information for at least one measurement report (MR), receiving, from the UE, an MR associated with an event detected by the UE based on the configuration information for the at least one MR, and transmitting, to at least one second BS, a first message including overhearing configuration information associated with a SRS transmitted from the UE to the first BS, wherein the overhearing configuration information is used for overhearing the SRS by the at least one second BS.
