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.
