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: Example measurement methods and apparatus are described. One example method includes obtaining a timer by a terminal device. The terminal device obtains two or more measurement configurations, where each of two or more measurement configurations includes a validity area and a measurement frequency corresponding to the validity area, and the validity area includes one or more cells. The terminal device measures, based on the measurement configuration, a measurement frequency corresponding to a validity area that matches a cell on which the terminal device camps, where the terminal device is in an idle state or in an inactive state, and the timer is not stopped and has not expired.

Abstract: A communication method for a dual connectivity system and a communication apparatus are disclosed, to support relaxing radio resource management (RRM) measurement. The method includes: A first network device determines that a terminal device is to deactivate a secondary cell group (SCG) of the terminal device; the first network device sends first information to the terminal device, where the first information indicates the terminal device to deactivate the secondary cell group SCG of the terminal device, to enable the terminal device to relax SCG RRM measurement after deactivating the SCG; and the terminal device relaxes the SCG RRM measurement after deactivating the SCG based on the first information. The first network device is a master node or a secondary station of the terminal device. In this way, when the SCG is deactivated, relaxing the

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.
