COMMUNICATION CONTROL METHOD AND USER TERMINAL

摘要

D2D communication is appropriately controlled even in an environment in which a user terminal inside the coverage and a user terminal outside the coverage both exist. A method includes: a step of receiving, by UE 100-1 included in a plurality of UEs 100, from UE 100-n included in the plurality of UEs 100, information related to the UE 100-n; and a step of selecting, by the UE 100-1, a control user terminal for controlling D2D communication, based on the information related to the UE 100-n, from among the plurality of UEs 100.

1. A first user terminal comprising:
a controller containing at least one processor and at least one memory, wherein in case that the first user terminal is out of coverage of a communication network, the controller is configured to execute processes of:
directly receiving first device-to-device (D2D) synchronization information from a second user terminal, the first D2D synchronization information including coverage information that indicates whether the second user terminal is in the coverage;determining, based on the coverage information, whether the second user terminal is in the coverage; andselecting the second user terminal as a synchronization reference of the first user terminal in response to determining that the second user terminal is in the coverage.
