METHODS AND APPARATUS FOR PROVIDING BASE STATION POSITION INFORMATION AND USING POSITION INFORMATION TO SUPPORT TIMING AND/OR FREQUENCY CORRECTIONS |
摘要 |
A wireless terminal receives base station position over an airlink, determines its relative position with respect to the base station and determines a timing adjustment correction. The wireless terminal applies the determined timing correction to control uplink signaling timing and achieve synchronization at the base station's receiver. The wireless terminal determines its relative velocity with respect to the base station and determines a Doppler shift adjustment which it adds to the uplink carrier frequency or to its baseband signal. A wireless terminal determines the position of a moving base station and determines timing and/or frequency corrections. Base station position is determined from the current time and stored information correlating the base station position with time, e.g., for a geo-synchronous satellite. Base station position information is determined from broadcast information, e.g., GPS base station position, for an aircraft base station. Wireless terminals may be mobile and include a GPS receiver for WIRELESS TERMINAL position determination. |
