WIPO Patent Application WO/2020/029283
Kind Code:
A1
Abstract:
Provided are a method and apparatus for sending a reference signal, a method and apparatus for receiving a reference signal, and a vehicle-mounted device and a terminal. The method for sending a reference signal comprises: determining transmission configuration information of synchronization signal blocks (VSSBs) in an NR V2X system, wherein the transmission configuration information comprises: a sending period of the VSSBs and a time-domain position of a VSSB sending time window within the sending period; and according to the transmission configuration information, sending the N VSSBs in the periodically appearing VSSB sending time window, wherein N is an integer greater than or equal to one; and each of the VSSBs comprises: a primary sidelink synchronization signal (PSSS), a secondary sidelink synchronization signal (SSSS), a physical sidelink broadcast channel (PSBCH) and a demodulation reference signal (DMRS). Using the method for sending a reference signal provided in the present disclosure ensures quick completion of time-domain synchronization between a vehicle-mounted device and a receiving terminal in an NR V2X system.
