METHOD AND APPARATUS FOR DERIVING FINE TIMING TO ASSIST POSITION ACQUISITION IN A COMMUNICATION NETWORK

摘要

In wireless communication systems network timing may assist position location operations. A user equipment may obtain a rough network time from a server to tag when a downlink frame is received. That time may be based on a network frame boundary, particularly for synchronous networks. An estimate of the one way delay, which may be half of a timing advance value, may be added to arrive at a fine timing estimate. The fine timing estimate may assist with position location when there is a delay by a position location receiver in determining the user equipment's location.
