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.

Abstract: An out-of-synchronization determining method and apparatus are provided. 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: A root cause failure determining method and an apparatus are provided. The method includes a first network element determines alarm information of N objects, where N is an integer greater than or equal to 2, and the first network element determines a root cause failure of the alarm information of the N objects based on an object association relationship, where the root cause failure is alarm information of M objects in the N objects, where M is a positive integer less than or equal to N. A root cause failure of a plurality of pieces of alarm information can be determined, and a service ticket can be dispatched for the root cause failure to reduce operation and maintenance costs.
