Abstract
A base station almanac (BSA) includes entries for a plurality of repeaters. An entry for a repeater includes location-determination parameters associated with that repeater, such as (i) a repeater forward link calibration (FLC) value that correct for transmission delay associated with the repeater and (ii) a center point of the repeater's coverage area. A measured power level and a measured phase of a wireless signal transmitted by a base transceiver station (BTS) and received by the mobile station are obtained. An expected received power level is calculated based on the measured phase and the transmit power level of the BTS. If the measured power level exceeds the expected received power level by at least a predetermined amount, then it is determined that the mobile station received the wireless signal via a repeater and one or more location-determination parameters associated with the repeater are used to determine the mobile station's location.
