APPARATUS FOR CONFIGURING POSITION OF FREQUENCY RESOURCE

A method and an apparatus relate to the field of communications technologies, and are used to configure a position of a transmission frequency resource according to a synchronization relationship between devices, so as to reduce frequency guard space, thereby effectively increasing a frequency resource that can be used to transmit data. The method specifically 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, thereby reducing residual interference between the devices; and using, by the first device in a manner of extending a bandwidth of a carrier frequency or a manner of carrier aggregation, saved frequency guard space after reconfiguration. The present invention is applicable to a wireless communications system that uses adjacent frequency bands.
