Method and apparatus for transmitting a synchronization carrier frequency signal, method and apparatus for receiving a synchronization carrier frequency signal

摘要

Embodiments of the present application disclose a method for transmitting a synchronous carrier frequency signal, a method for receiving, and an apparatus. The transmitting method includes: obtaining, by a first access point, synchronization carrier frequency information, wherein the synchronization carrier frequency information is used to establish a synchronization carrier frequency channel for at least one second access point; transmitting, by the first access point, synchronization carrier frequency information to at least one second access point; generating at least two sync carrier frequency signals, wherein the at least two sync carrier frequency signals are used to set an operating radio frequency reference clock of the at least one second access point, and the frequency difference between the at least two sync carrier frequency signals is fixed is the value of -; and transmitting, by the first access point, a synchronization carrier frequency signal on a synchronization carrier frequency channel. In the method, the at least one second access point determines a synchronization carrier frequency channel based on the synchronization carrier frequency information, and processes the received synchronization carrier frequency signal. A frequency difference obtained between two or more sync carrier frequency signals is a fixed value. Therefore, since the same operating radio frequency reference clock is output, the frequency difference between different access points is eliminated.
