1. A method, comprising:
receiving, by a terminal, first indication information from a first access network device, wherein the first indication information indicates a timing offset of a first carrier and a second carrier, the timing offset is an offset between a timing of a downlink communication of the first carrier and a timing of an uplink communication of the second carrier, wherein the second carrier is an uplink frequency division duplex (FDD) carrier using a first radio access technology (RAT) and a second RAT, and wherein the first carrier uses only the first RAT,
wherein the first RAT is new radio (NR) and the second RAT is Long Term Evolution (LTE); and
determining, by the terminal, the timing of the uplink communication of the second carrier based on the timing of the downlink communication of the first carrier and the timing offset.
