  • Patent number: 9301271
    Abstract: The present disclosure relates to the technical field of LTE-A, and discloses a method for air interface synchronization between base stations. A base station to be synchronized, which simultaneously monitors a plurality of neighboring base stations, can select one neighboring base station to perform time-service synchronization in accordance with different criteria in order, such as whether CoMP is necessary, the time-service hop count, time-service delay, and the CQI level (channel quality indicator) and the like. That is, the most suitable synchronization source is determined according to a certain priority order. Such solution both applies to a phase of initial establishment of air interface self-synchronization between base stations, and also to a phase of periodic synchronization maintenance. In addition, the technical effect of such solution is particularly prominent in the case of intensively arranged Small Cells.
