Methods, Systems, And Computer Program Products For Over The Air Synchronization For Cellular Networks

摘要

Methods and systems are described for over the air synchronization in a cellular network. In one aspect, data that is in the presence of interference either from other proximate base stations or from a local synchronization base station is received from a base station that will be synchronized to. A joint signal processing technique is employed on the data to obtain known downlink reference signals having sufficient signal-to-interference plus noise ratio (“SINR”) for time or frequency synchronization. Time or frequency synchronization is determined based on the known downlink reference signals.

1. An over the air synchronization method in a cellular network, the method comprising:
receiving, from a base station that will be synchronized to, data that is in the presence of interference either from other proximate base stations or from a local synchronization base station; joint signal processing the data to obtain known downlink reference signals having sufficient signal-to-interference plus noise ratio (“SINR”) for time or frequency synchronization; and determining time or frequency synchronization based on the known downlink reference signals.
