Abstract: A method includes a first module of a terminal device sends a first request message to a second module, obtains first information from the second module, and assists cell handover based on a first cell handover list. The first request message is used to request the first cell handover list corresponding to a first TAC, which is a TAC of a current cell of the terminal device, and the first information indicates the first cell handover list. The terminal device may store a cell list corresponding to each line in advance. When the terminal device moves on a line, the terminal device may determine, based on the first TAC, the cell list corresponding to the line to perform cell handover.

Abstract: A terminal synchronization method and a terminal relate to the communications field, where the terminal sends synchronization signals in a distributed manner by controlling a sequence for sending the synchronization signals such 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: This application provides a physical downlink control channel processing method and a related device. In the method, a search space may be determined based on a first radio network temporary identifier, where the search space is a set of M candidate physical downlink control channels; and a target physical downlink control channel is detected from the search space based on a second radio network temporary identifier, where the first radio network temporary identifier is a radio network temporary identifier of a first device or a second device, the second radio network temporary identifier is the radio network temporary identifier of the second device, first downlink control information carried by the target physical downlink control channel is information that is scrambled by using the second radio network temporary identifier and that is used to schedule the second device, and the second device communicates with a network by using the first device.

Abstract: This application provides a method that includes the step of receiving, by a first device in a first time domain position, first scheduling information. The first scheduling information includes first indication information sent by a network device, wherein the first indication information is used to indicate a first interval. The method further comprises sending, by the first device, second scheduling information including second indication information to a second device in a second time domain position, wherein the second indication information is used to indicate a second interval, which is the difference between the first interval and a third interval. The second scheduling information is used by the second device to determine the target time domain position used by the second device to determine a time domain resource used to send and/or receive data.
