Communication method, access network device, and terminal

An apparatus, comprising one or more processors configured to:

• determine a timing offset of a first carrier and a second carrier, wherein the timing offset is 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
• send first indication information, wherein the first indication information indicates the timing offset of the first carrier and the second carrier.

A non-transitory computer-readable storage medium comprising instructions which, when executed by a computer, cause the computer to:

• determine a timing offset of a first carrier and a second carrier, wherein the timing offset is 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
• send first indication information, wherein the first indication information indicates the timing offset of the first carrier and the second carrier.
