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: A transmission direction configuration method, a device, and a system are described that relate to the field of communications technologies. A terminal device receives a first indication information from a network device, the first indication information indicates a configuration of uplink and downlink transmission directions. The configuration describes types, a number, and a distribution of resource elements comprised in one period. Moreover, the resource granularity comprises a time domain granularity, the time domain granularity comprises (OFDM) symbol. The types of the resource elements comprise at least one of an uplink resource element, a downlink resource element, or a switch resource element between the downlink resource element and the uplink resource element. An information transmission is performed that is indicated by the first indication information, of the uplink and/or downlink transmission directions.

Abstract: A method for measuring channel state information (CSI), a network-side device, and a user equipment (UE). The method includes determining, by a network-side device, configuration information, where the configuration information is used to configure UE to perform CSI measurement on different subframe sets on a flexible frequency band or sub-bands of the flexible frequency band, the subframe sets are determined by the network-side device based on uplink-downlink configurations of subframes on the flexible frequency band or the sub-bands of the flexible frequency band in a target cell and at least one neighboring cell of the target cell, and the flexible frequency band is a frequency band on which a transmission direction is configurable, and sending, by the network-side device, the configuration information to the UE to perform the CSI measurement based on the configuration information.

Abstract: Example handover methods and devices in an ultra-dense network are disclosed. One example method includes the following operations. A source base station sends a first message to a target base station, where the first message carries an arrival time indication of a terminal, and the arrival time indication is used to indicate a time at which or a time range in which the terminal is to access the target base station. The source base station receives a second message fed back by the target base station, where the second message carries a granted resource that is allocated for the arrival time indication of the terminal. The source base station adds the granted resource to a command message, and sends the command message to the terminal.
