Abstract: This application provides an out-of-synchronization determining method and apparatus. The method includes: receiving, by a control network element, interference metrics sent by N base stations; determining, by the control network element based on the interference metrics, M first to-be-inspected base stations in the N base stations and/or neighboring stations of the N base stations; determining, by the control network element, P second to-be-inspected base stations, where the P second to-be-inspected base stations are base stations meeting a detection condition that are selected from the M first to-be-inspected base stations, and the detection condition is that a characteristic sequence broadcast by the first to-be-inspected base station at a specified position in a radio frame is not received by any neighboring station at the specified position; and determining, by the control network element, an out-of-synchronization base station in the P second to-be-inspected base stations.

Abstract: Example base station determining methods and example servers are disclosed, where the solution is used to determine an out-of-synchronization base station in a network. In one example, at least one synchronization domain is determined, where any two neighboring base stations in the synchronization domain are in a relative clock synchronization relationship. Then, a first synchronization domain is determined based on the at least one synchronization domain, where each base station in the first synchronization domain is a synchronization base station. A second synchronization domain that is in the at least one synchronization domain and that has a relative clock out-of-synchronization relationship with the first synchronization domain is then determined, to determine that each base station in the second synchronization domain is an out-of-synchronization base station.

Abstract: Communication method and base stations are provided. One example includes determining, by a base station, that co-channel interference exists. For N consecutive symbols before a guard period (GP) in a special subframe in a radio frame, the base station sends a signal by using M1 middle resource blocks (RBs) of the N symbols, and reserves use of an RB other than the M1 RBs in the N symbols, where both N and M1 are positive integers.
