Abstract: This application provides a data sending method, a data sending apparatus, and a terminal device, to improve utilization of a configured grant resource. The method includes: A terminal device receives a configuration message from a network device. The configuration message is used to indicate a configured grant, and the configuration message includes information about a timer corresponding to the configured grant. The terminal device determines that the configured grant is used for a HARQ process, and starts the timer for the HARQ process. To-be-sent data in the HARQ process is data on a first logical channel. During running of the timer, when there is to-be-newly-transmitted data on a second logical channel, the timer stops running, or a running state of the timer is ignored. The data on the second logical channel is sent by using the configured grant.

Abstract: Embodiments of the present disclosure provide a downlink synchronization method, an apparatus, and a system, and relate to the communications field, so as to reduce downlink synchronization complexity and improve downlink synchronization efficiency. According to the downlink synchronization method, abase station sends downlink synchronization reference information to UE by using dedicated signaling or a system message, where the downlink synchronization reference information is used to instruct the UE to perform downlink synchronization in a second cell by referring to a downlink synchronization channel of a first cell; and the base station sends, in the second cell according to location information of the UE, a beam including a downlink synchronization channel to the UE, where the first cell and the second cell include an overlapped coverage area. The embodiments of the present disclosure are applied to synchronization channel sending.

Abstract: This application provides a measurement configuration method and an apparatus. The method includes: determining that a serving cell changes from a first cell to a second cell; and updating or deleting a current measurement window configuration. The measurement window configuration is used to indicate a time domain position at which a terminal device measures a downlink reference signal. According to the solution provided in this application, when the serving cell of the terminal device changes, the current measurement window configuration of the terminal device is updated or deleted.

Abstract: This application provides method and apparatus for RRC state control. An access network device obtains RRC connected inactive state indication information of UE. When the UE leaves an RRC connected state, the access network device determines, based on the RRC connected inactive state indication information, that the UE enters an RRC connected inactive state or an RRC idle state, so that the access network device can control, based on a state of the UE, the UE to enter an appropriate RRC state, thereby reducing signaling overheads and improving system performance.
