Title:
SYNCHRONIZATION SIGNAL TRANSMITTING METHOD AND DEVICE, AND READABLE STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/116286
Kind Code:
A1
Abstract:
Embodiments of the present application provide a synchronization signal sending method and device, and a readable storage medium, and are applied to D2D communication scenes. The method comprises: a UE monitors nearby synchronization signals before broadcasting a synchronization signal; and if synchronization signals transmitted by other UEs are monitored, excluding sub-frames overlapped with the synchronization signals transmitted by other UEs in a transmission period (i.e., the range of [0, T)), randomly selecting a sub-frame as the sub-frame position where a synchronization signal is transmitted by the UE, and transmitting the synchronization signal at the sub-frame position. According to the embodiments of the present application, the problem of interference of synchronization signals among UEs due to the fact that a plurality of UEs transmit synchronization signals at the same position can be solved, thereby improving the success rate of timing synchronization among the UEs and improving the communication success rate among the UEs.
