Abstract
A wireless device performs a transmission on a primary and auxiliary access channels to enable reception by at least three base stations. The base stations perform a measurement on the received transmission, e.g., a time of arrival of the transmission. The base stations report their measurements to a position determination entity. The position determination entity estimates geographic position of the wireless device. One method used by the position determination entity includes tri-lateralization based on the received measurement reports.
