Abstract
The present disclosure provides a communication method and apparatus, the method includes: sending, by a first network device, a handover request to a second network device, where the handover request is used for handing over a target network device that serves a terminal device from the first network device to a second network device, and the handover request includes a TA of the terminal device with the second network device, or includes location information of the terminal device and a movement trajectory of the terminal device for determining the TA of the terminal device with the second network device. In this way, as the second network device after handover has determined the timing advance TA of the terminal device with the second network device, an uplink transmission time indicated by the network device can be prevented from being before a downlink reception time, ensuring usability of uplink resource configuration.
