Abstract: A communication method and apparatus are provided, relate to the field of communication technologies, and are used to alleviate a problem of how to set a PDCP window variable when a terminal device performs packet data convergence protocol PDCP entity suspending or PDCP entity re-establishment. The method may include: The terminal device receives, from a network device, first information indicating packet data convergence protocol PDCP suspending, and sets, to an initial value, a PDCP window variable associated with a radio bearer RB other than a first RB. The first RB may include a multicast and broadcast service radio bearer MRB.

Abstract: This application discloses a communication method and a related apparatus. In the method, a terminal triggers TA reporting and sends a TA report. The TA report includes position information or TA information of the terminal. If the TA report is successfully sent, the triggered TA reporting is canceled. In other words, before the TA report is successfully sent, the triggered TA reporting is not canceled. In this way, when there is another available uplink resource, the terminal may send the TA report again over the uplink resource. Therefore, a delay caused by re-triggering the TA reporting is reduced, and a success rate of reporting the TA report is increased.

Abstract: This application provides a communication method and apparatus. The communication method includes: A network device sends a first message to a first terminal device UE, where the first message includes information about a first resource, and the first resource is to be used to transmit a second message; and when the network device receives the second message from the first UE by using the first resource, the network device determines that the first UE is not faulty, where the second message indicates that the first UE is not faulty. Therefore, the network device may determine, based on the second message sent by the first UE, that the first UE is not faulty. This ensures that service reliability is not affected by a fault of a terminal device, avoids forced termination of service transmission, and ensures transmission reliability.
