Abstract: 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.

Abstract: A first access network device determines a timing offset of a first carrier and a second carrier. The timing offset is an offset between timing of downlink communication of the first carrier and timing of uplink communication of the second carrier. The first carrier is a carrier using a first radio access technology (RAT), and the second carrier is an uplink frequency division duplex (FDD) carrier using the first RAT and a second RAT. The first access network device sends first indication information to a terminal. The first indication information indicates the timing offset, and the timing offset is used to determine the timing of the second carrier. Based on this scheme, the terminal can use a shared frequency band resource of LTE, thereby improving resource utilization.
