Abstract: A measurement configuration method includes a network device that determines when a bandwidth part (BWP) occupied by a terminal device is switched from a first BWP to a second BWP. The network device sends first information to the terminal device, indicating whether configuration information of a first measurement window takes effect when the terminal device occupies the second BWP and indicating whether the first measurement window is configured for the first BWP.

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 cell measurement method and terminal device. The cell measurement method includes: first determining, by a terminal device, whether a cell meets a first preset condition; and when the terminal device determines that the cell meets the first preset condition, measuring or evaluating, by the terminal device, the cell by using a first period; or when the terminal device determines that the cell does not meet the first preset condition, measuring or evaluating, by the terminal device, the cell by using a second period, where the cell being a serving cell or a neighboring cell of the terminal device corresponds to different first preset conditions, and the first period is different from the second period.

Abstract: A resource indication method includes generating, by a network device, first control information, where the first control information is used to indicate a frequency resource occupied to transmit data in N time resource units, and N is a positive integer greater than or equal to 2; and sending, by the network device, the first control information to a terminal device. Therefore, the network device may indicate, for the scheduled N time resource units, the frequency resource occupied to transmit data in the N time resource units.

Abstract: A communication method and a communications device are disclosed. A first device in a communications system separately sends, to a second device, responses used to indicate a transmission result of target data: a first response and a second response. An indication manner of the first response is different from an indication manner of the second response. This approach can improve flexibility of a response indication manner. Therefore, the communications system can flexibly adjust indication manners of responses sent at different times to ensure indication precision of the responses while reducing transmission resources of the responses.

Abstract: The application provides method for communicating channel state information (CSI) in a communication network. The method is as follows: An apparatus determines whether a length of CSI is less than a preset length; and adds a padding bit to the CSI when determining that the length of the CSI is less than the preset length, where a length of CSI obtained by adding the padding bit is consistent with the predetermined length. The CSI obtained by adding the padding bit is communicated in the communication network.
