<p>Method and Apparatus to Derive System Timing at a Wireless Base transceiver Station (BTS). The present invention relates to wireless communication networks and, more particularly, to timing information in wireless communication networks. A method for providing reference timing to a BTS, the method comprising of the BTS sending a message to a network controller via a station, wherein the message requests for round trip delay time incurred by the message; the BTS estimating a timing offset from a response and determining the correction to be made to the reference timing using the timing offset due to the one way delay from the station transmitting the pilot signal, the actual PN offset at which the station transmits the pilot signal and the actual offset at which the pilot signal is received at the BTS; and the BTS making the correction to the reference timing.</p> |
