Abstract
A mobile station is configured to perform a method for uplink timing alignment in a wireless network. The method includes receiving a first downlink synchronization signal from a base station on a first beam pair at a first time associated with a first propagation delay. The method also includes receiving a second downlink synchronization signal from the base station on a second beam pair at a second time associated with a second propagation delay. The method further includes determining a second timing advance for the second beam pair based on a known first timing advance for the first beam pair and a time difference between the first time and the second time.
