Because the D2D terminal cannot decode the PSBCH sent by the VUE, the process of finally selecting the synchronization source for the D2D terminal will be affected
[0010] So far, on the carrier where V2X communication and D2D communication coexist, how to avoid the impact of SLSS and PSBCH sent by VUE on D2D terminals, there is no mature implementation plan

Abstract
The application discloses a method for sending a synchronization signal and a PSBCH (Physical Sidelink Broadcast Channel) in V2X communication, which includes the following steps: VUE (Vehicular User Equipment) determines the value of N<ID><SL> according to the reference synchronization source thereof, wherein N<ID><SL> represents a sidelink synchronization source ID; the VUE determines an SLSS (Sidelink Synchronization Signal) different from a D2D (Device-to-Device) system and / or a DMRS (Demodulation Reference Signal) of a PSBCH according to the value of N<ID><SL>, wherein the SLSS includes a PSSS (Primary Sidelink Synchronization Signal) and an SSSS (Secondary Sidelink Synchronization Signal), and the DMRS of the PSBCH is determined by the DMRS sequence of the PSBCH and the orthogonal mask of the DMRS of the PSBCH; and the VUE sends the SLSS and the PSBCH. The invention further discloses a device for sending a synchronization signal and a PSBCH in V2X communication. By using the method and the device, a D2D terminal can be prevented from being guided to measure S-RSRP (Sidelink-Reference Signal Receiving Power) at the DMRS position of a PSBCH sent by VUE or from performing measurement at the DMRS position of a PSBCH sent by VUE to get an S-RSRP value satisfying a synchronization source reselection condition, and the influence of VUE on the D2D terminal synchronization process can be avoided simply and effectively.
Description
technical field [0001] The present application relates to the field of mobile communication technologies, in particular, the present application relates to a method and device for transmitting V2X synchronization signals and PSBCH in a Vehicle to Vehicle / Pedestrian / Infrastructure / Network (V2X, Vehicle to Vehicle / Pedestrian / Infrastructure / Network) communication system. Background technique [0002] At present, the device-to-device (D2D, Device to Device) communication technology has been accepted by the third generation partnership project (3GPP) standard by virtue of its great potential value in the field of public safety and ordinary civilian communication, and has been listed in 3GPPRel-12 The standardization of some functions has been realized, including the mutual discovery of D2D terminals in the scenario of cell coverage, the scenario of cell coverage (IC, In Coverage), the scenario of partial cell coverage (PC, Partial Coverage) and the scenario of no cell coverage (OC...
