Claim of US Patent No. 11,071,080


1. An information sending method performed by a first access network device, wherein the method comprises:determining a timing adjustment amount, wherein the timing adjustment amount is an adjustment amount between a first timing at which the first access network device sends a first downlink signal to a first terminal device on a first frequency band and a second timing at which the first access network device sends a second downlink signal to the first terminal device on a second frequency band, wherein the first frequency band and the second frequency band are paired frequency bands;
sending first indication information to the first terminal device, wherein the first indication information indicates the timing adjustment amount;
sending second indication information to the first terminal device, wherein the second indication information indicates that the first terminal device uses the timing adjustment amount indicated by the first indication information; and
sending the first downlink signal to the first terminal device on the first frequency band, wherein a second access network device receives an uplink signal from a second terminal device on the first frequency band, and when the first downlink signal reaches the second access network device,a symbol carrying the first downlink signal is aligned with a symbol carrying the uplink signal; or
a time difference between a symbol carrying the first downlink signal and a symbol carrying the uplink signal is less than or equal to a length of a cyclic prefix, wherein the cyclic prefix is a cyclic prefix of the symbol carrying the first downlink signal or a cyclic prefix of the symbol carrying the uplink signal, whichever of the cyclic prefixes has a smaller length.
