Abstract: An information receiving method, an information sending method, and a device are provided. Under these methods, a timing adjustment amount can be determined by a first access network device. 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. The first frequency band and the second frequency band are paired frequency bands. First indication information can be sent, by the first access network device, to the first terminal device. The first indication information indicates the timing adjustment amount.
