Abstract

Provided are a synchronization signal bearing method and device. The synchronization signal bearing method of the present invention comprises: a first user equipment determining a priority parameter of a synchronization signal; the first user equipment determining a resource for bearing the synchronization signal according to the priority parameter, wherein a configuration of the resource indicates the priority parameter; and the first user equipment sending the synchronization signal to a second user equipment by using the resource, so as to enable the second user equipment to determine a synchronization signal of the second user equipment. The embodiments of the present invention enable a determination manner for a synchronization signal of a D2D communication system to be more flexible.

Description

technical field [0001] The embodiments of the present invention relate to the field of communication technologies, and in particular, to a synchronization signal bearing method and user equipment. Background technique [0002] Device to Device Proximity Service (D2DProSe for short) has become the third generation mobile communication partnership organization (3rd Generation Partnership Project, 3GPP for short) Long Term Evolution (LTE for short) system Rel.12 research topics. Using the LTE physical layer to provide D2D Prose can not only enrich the service range of the LTE system, but also enable D2D Prose to be used by more users. Among them, ProSe includes D2D discovery and D2D communication. D2D discovery refers to user equipment with D2D function discovering signals to know the existence of each other. D2D communication refers to direct communication between devices with D2D function. When designing D2D communication, system time synchronization (including frame synchr...
