Title:
METHOD AND DEVICE FOR TRANSMITTING SYNCHRONIZATION SIGNAL BY MEANS OF SIDELINK TERMINAL IN WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/027572
Kind Code:
A1
Abstract:
Provided is a method for transmitting a signal by means of a sidelink terminal in a wireless communication system, according to an embodiment of the present invention. The method for transmitting a signal comprises the steps of: selecting any one of an eNB and a gNB as a synchronization reference; and transmitting a sidelink channel/signal including an SSB (SS/PBCH block) on the basis of synchronization of the base station selected as the synchronization reference, wherein when dual connectivity (DC) is configured for the terminal, the terminal selects a master NB (NodeB) among the eNB and the gNB as the synchronization reference.
