Abstract: Example methods and apparatuses are provided. An example method includes receiving first indication information. The first indication information indicates that a trajectory of a first terminal device matches a trajectory of a second terminal device. The method further includes sending second indication information to the first terminal device. The second indication information indicates to change a trajectory information reporting periodicity to a second periodicity, or the second indication information indicates to suspend trajectory information reporting. The second periodicity is greater than a first periodicity, and the first periodicity is the trajectory information reporting periodicity before the first indication information is sent.

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: 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: This application provides a communication method and apparatus, and relates to the field of communication technologies. The method may include: A network device performs integrity protection on system information by using a first private key, and sends the system information, where the system information includes a first public key corresponding to the first private key and/or an index of the first public key. Correspondingly, a terminal device receives the system information from the network device, and if determining that the first public key is valid, the terminal device verifies integrity of the system information by using the first public key. According to this method, on one hand, the terminal device can effectively identify validity of the system information. On the other hand, because the system information includes the first public key and/or the index of the first public key, flexible update of an asymmetric key can be implemented.
