Over-the-air synchronization of radio nodes in a radio access network

Over-the-air synchronization of radio nodes in a radio access network

A method is provided for synchronizing timing in phase and frequency of clocks associated with a plurality of radio nodes (RNs) in a small cell radio access network (RAN) having an access controller operatively coupled to each of the RNs. In accordance with the method, a donor list is generated for...

description A method is provided for synchronizing timing in phase and frequency of clocks associated with a plurality of radio nodes (RNs) in a small cell radio access network (RAN) having an access controller operatively coupled to each of the RNs. In accordance with the method, a donor list is generated for each given RN in the RAN. The donor list represents an ordered list of potential wireless access points that are able to serve as a source of a wireless sync signal for the given RN. The donor lists are distributed to the respective RNs. An access point is selected by each of the RNs from their respective donor lists to use as a sync signal source. Each of the RNs synchronize their respective clocks in phase and frequency using wireless sync signals received from the respective selected access points.
