Abstract: An apparatus 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 apparatus 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.

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.
