Synchronization for V2X communication
A user equipment (UE) is described. Higher layer circuitry is configured to receive information on a sidelink bandwidth part and a resource pool for sidelink within the sidelink bandwidth part. Transmitting circuitry is configured to transmit one or more blocks. Each block includes a primary sidelink synchronization signal (PSSS), a secondary sidelink synchronization signal(SSSS), a physical sidelink broadcast channel (PSBCH) and a demodulation reference signal (DMRS) associated with the PSBCH within the resource pool. A sequence of the PSSS is generated by using a synchronization source identity (ID) or a part of the synchronization source ID. A sequence of the SSSS is generated by using the synchronization source ID or a part of the synchronization source ID. The PSBCH includes a parameter related to an index of the block and the parameter is associated with a slot index.
