Title:
USER DEVICE AND SYNCHRONOUS SIGNAL TRANSMISSION METHOD
Document Type and Number:
WIPO Patent Application WO/2019/030935
Kind Code:
A1
Abstract:
This user device, which exists as part of a wireless communication system, comprises: a setting information management unit for holding setting information for transmitting a synchronous signal using a specific carrier in a carrier group having a plurality of carriers which can be used in D2D communication; and a signal transmission unit which transmits a synchronous signal using the specific carrier, on the basis of the setting information. The signal transmission unit is constituted in such a manner that a synchronous signal is not transmitted on a carrier other than the specific carrier in the carrier group, if predetermined conditions are satisfied.
