Abstract: Achieving phase synchronization in single frequency networks may be useful in various communication systems. For example, the use of synchronous Ethernet, timing over packet, and radio interface based synchronization (RIBS) may be applied in mobile and/or data communication networks. Certain embodiments improve phase accuracy using a hybrid synchronization method beyond standard RIBS and clustering carriers using the same transmission waveforms across carriers. Certain embodiments also select a master transmission point to maximize the signal quality of the composite waveforms in a cluster.
