Abstract

A baseband unit independently determines one or both of an uplink delay or a downlink delay for frames transmitted from the baseband unit to a remote radio head based on a round-trip time between the baseband unit and the remote radio head and times determined at the baseband unit, a downlink node associated with the remote radio head, and an uplink node associated with the remote radio head. The times are determined at different nodes after an interval of frames. The baseband unit then may determine a location of user equipment based on one or both of the uplink delay or downlink delay.
