Abstract

A distributed algorithm is proposed to synchronize femtocells through air interface. A femtocell could listen to the synchronization signals of its neighbouring base stations to extract time information of these neighbours. Then it updates its time according to the neighbours’ time, directed by a global optimization criterion in a distributed manner. Finally all femtocells will have same time information. A common framework is summarized to deal with many scenarios with different configuration of weight coefficients.

Keywords: Wireless communication femtocell synchronization gossip algorithm distributed communication
