METHOD AND DEVICE FOR PERFORMING LINK ADAPTATION IN WIRELESS COMMUNICATION SYSTEM

摘要

One embodiment of the present invention relates to a method by which a device-to-device (D2D) terminal performs link adaptation in a wireless communication system, the D2D link adaptation method comprising the steps of: performing measurement on a resource region to be used for D2D communication; and determining whether the measurement performance result satisfies a trigger condition, wherein if the trigger condition is satisfied for a first time with respect to the resource region, first link adaptation is performed, and if the trigger condition is satisfied for n times (n>=2) with respect to the resource region, second link adaptation is performed.
