The terminal receives configuration information from a network device, wherein the configuration information includes two timing advance groups (TAGs) corresponding to one cell, and each TAG corresponds to one timing advance (TA). The terminal receives a plurality of random access response messages from the network device, wherein each random access response message is usable to indicate a TA corresponding to one of the two TAGs.

Abstract: A cell handover method and an apparatus. Indication information is received from a source cell, where the indication information indicates to a first transmission configuration indicator TCI state and cell handover; initiating random access to a target cell according to the indication information. In response to first response information returned by the target cell being received, second response information is returned to the source cell, where the second response information indicates that the first TCI state is successfully activated. Cell handover is implemented through beam switch to reduce a delay of a terminal device during the cell handover. The terminal device returns the second response information to the source cell only after receiving the first response information returned by the target cell.

Abstract: The present disclosure relates to channel conflict processing methods and apparatus. In one example method, when a terminal device establishes a connection relationship with a source cell, and sends a connection request to or establishes a connection relationship with a target cell, the terminal device detects whether an uplink channel conflict occurs on an uplink channel of the source cell and an uplink channel of the target cell, where the source cell and the target cell are infra-frequency or intra-band contiguous inter-frequency. If the terminal device determines that an uplink channel conflict occurs, the terminal device sends a signal on an uplink channel with a higher priority between the uplink channel of the source cell and the uplink channel of the target cell.
