USER TERMINAL AND MOBILE COMMUNICATION SYSTEM

摘要

UE (100) is provided with UE (100) which, when D2D communication that is direct device-to-device communication is performed in a D2D group composed of a plurality of pieces of UE (100), determines an allocation pattern of radio resources used for D2D communication. The UE (100) determines the allocation pattern on the basis of a temporary identifier assigned from a network such that the radio resources used for D2D communication are distributed in a frequency direction and/or a time direction.
