Abstract: A method, system, and device for downlink transmission. A downlink signal is sent to a UE in an available frequency band of an uplink frequency band, and no signal is sent or received in a guard frequency band of the uplink frequency band, where the guard frequency band is located in a highest-frequency part and/or a lowest-frequency part of the uplink frequency band. Because no signal is sent or received in the guard frequency band of the uplink frequency band, interference to communication of a UE in an adjacent frequency band is reduced when the uplink frequency band is occupied for downlink transmission, thereby improving system performance.

Abstract: Embodiments of this application provide a synchronization signal sending method and apparatus. The method includes: obtaining an initial synchronization sequence, where a spectrum width corresponding to the initial synchronization sequence is greater than a bandwidth of a synchronization channel and is less than a sum of the bandwidth of the synchronization channel and a system protection bandwidth; dividing the initial synchronization sequence into N sub-synchronization sequences; carrying the N sub-synchronization sequences on N time-domain symbols; and sending the N time-domain symbols to a receiving apparatus. According to the synchronization signal sending method provided in the embodiments of this application, a bandwidth loss of a synchronization signal is reduced, and utilization and synchronization performance of a system synchronization bandwidth are improved.
