TWO-STAGE DEVICE-TO-DEVICE (D2D) DISCOVERY PROCEDURES

摘要

First user equipment transmits a first synchronization signal and a second synchronization signal that are assigned to the first user equipment for device-to-device (D2D) communication. The first synchronization signal indicates a timing reference for D2D communication and a combination of the first synchronization signal and the second synchronization signal indicate resources allocated to the first user equipment to transmit discovery information for D2D communication. First user equipment detects a first synchronization signal and a second synchronization signal that are assigned to second user equipment for D2D communication.
