Example uplink signal sending methods and apparatus are described. One example method includes determining, by a terminal, a symbol that needs to be punctured, and sending the uplink signal by the terminal based on the symbol that needs to be punctured. Further, the terminal may notify the source cell and/or the target cell of the symbol that needs to be punctured, so that the source cell or the target cell improves, according to a notification indication, decoding on the uplink signal sent by the terminal.
