Abstract: Embodiments of this application relate to the communications field, and provide a terminal synchronization method and a terminal. A terminal sends synchronization signals in a distributed manner by controlling a sequence for sending the synchronization signals, so that terminals in a vehicle to vehicle communications system can have uniform timing. The method includes: obtaining, by a terminal, a configurable transmission period for sending a first synchronization signal; and sending, by the terminal, the first synchronization signal based on the configurable transmission period.

Abstract: A signal resource configuration method, a terminal, and an access network device to reduce impact on an existing standard and save Channel State Information Reference Signal (CSI-RS) resources. The method includes obtaining, by the access network device, a 2N-port CSI-RS resource sequence number, and sending, by the access network device, the 2N-port CSI-RS resource sequence number to a terminal device, where the 2N-port CSI-RS resource sequence number notifies the terminal device of an N-port CSI-RS resource in two adjacent physical resource blocks (PRBs), and N is a positive integer.

Abstract: A device-to-device (D2D) communication method and a D2D terminal device, where the method includes determining, by a first device, a time that the first device is out of coverage of a synchronization source after leaving the coverage of the synchronization source determining, by the first device, target timing based on the time, and performing, by the first device, D2D communication based on the target timing. Hence, the target timing can be selected more accurately for the first device.

Abstract: A computer-implemented method includes sending, by an access node, to a user equipment (UE) configuration information for a beam quality reference signal (BQRS) that is associated with a discontinuous reception (DRX)-ON period used for sending a physical downlink control channel (PDCCH) to the UE, wherein the BQRS has a spatial quasi-collocated (QCL) relationship with either the PDCCH or a demodulation reference signal (DMRS) of the PDCCH. The method further includes sending, by the access node, the BQRS to the UE.
