Abstract: This application provides a network device-based communication method, where channel resources are divided according to a specific rule. The method includes: determining, by a network device, at least two channels, where a spacing between center frequencies of two adjacent channels in the at least two channels is a positive integer multiple of a subcarrier spacing or a positive integer multiple of a resource block RB spacing; and communicating, by the network device, by using at least one of the at least two channels. Channel resource division is determined based on the spacing between center frequencies of two adjacent channels, implementing adaptation to an application scenario in which a bandwidth is flexible.

Abstract: The present disclosure relates to the communications field, and provides a frame synchronization method, user equipment, and a base station, to implement frame time synchronization in a high-low frequency hybrid communications system. In one example method, a user equipment completes synchronization of a first frequency frame, determines a first moment of the synchronization of the first frequency frame, obtains a receive time difference, and completes synchronization of a second frequency frame according to the receive time difference and the first moment. The receive time difference is a time difference between a moment at which the user equipment receives the second frequency frame and a moment at which the user equipment receives the first frequency frame.

Abstract: A base station, a small cell, and a method for scheduling a communications link resources are provided. A first small cell reports load information and channel state information of a channel between the first small cell and a neighboring second small cell to a base station. The first small cell receives link pre-scheduling signaling from the base station. The link pre-scheduling signaling includes wireless resource occupation information that indicates an occupancy of a wireless resource of the first small cell by a backhaul link. The first small cell allocates a first wireless resource in available wireless resources to the backhaul link according to the channel state information and the wireless resource occupation information, and allocates a second wireless resource in the remaining available wireless resources to an access link used for data transmission between the first small cell and a user equipment device.
