Abstract: Example cell measurement methods and apparatus are described. One example method includes obtaining, by a first network device, a first paging parameter of a cell served by a second network device. The first paging parameter is used to indicate a first time domain position at which a terminal device monitors a paging message from the second network device. The first network device sends a reference signal based on the first paging parameter. A time domain position of the reference signal is determined based on the first time domain position.

Abstract: Embodiments of this application provide a synchronization signal/physical broadcast channel block (SSB) measurement method and an apparatus. One example method includes that a terminal device receives first information and second information. The first information indicates a time domain position of an SSB sent by a serving cell, and the second information indicates a set of SSBs that the terminal device needs to measure and that are sent by a neighboring cell. The terminal device measures, in a first measurement window based on the first information, the SSB sent by the serving cell. The terminal device measures, in a second measurement window based on the second information, the SSB sent by the neighboring cell.

Abstract: Embodiments of the application provide a communications method and apparatus. A target cell is determined based on measurement results of N measured cells and a preset value when there is a first cell satisfying a report trigger condition. A measurement result of the target cell is sent to a base station. A terminal may not only send the measurement result of the cell satisfying the trigger condition to the base station, but also send a measurement result of another cell to the base station. In this way, a quantity of cells that can be selected during determining of handover can be increased, to help the base station select a suitable cell for the terminal.

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 a communication method and apparatus, to determine a DRX cycle. The method includes: receiving data in an active time of a current DRX cycle; when a DRX inactivity timer of the current DRX cycle expires, determining a type of a next DRX cycle depending on whether at least some data received in the active time is associated with a DRX short cycle, where if the at least some data is not associated with a DRX short cycle, the next DRX cycle is a DRX long cycle, or the type of the next DRX cycle is the same as that of a DRX cycle previous to the current DRX cycle. When the DRX inactivity timer expires, the type of the next DRX cycle can be more flexibly determined, and may not necessarily be a DRX short cycle. This can save power of a device to some extent.
