Abstract
A method and an apparatus are used to configure a position of a transmission frequency resource according to a synchronization relationship between devices, includes: adjusting, by a first device, synchronization according to synchronization information of a second device, in a case in which the first device is synchronous with the second device, or the second device can adjust a configured frequency resource, configuring a frequency resource close to an edge of a frequency band, where the frequency resource is used to transmit data, and notifying first user equipment; in a case in which the devices are synchronous, adjusting, by the first device and the second device, a start moment or an end moment of transmitting or receiving a signal; and using, by the first device in a manner of extending a bandwidth of a carrier frequency or a manner of carrier aggregation.
