Abstract
Embodiments of a base station, a communication system and a method for determining current location information of a mobile station using uplink time-difference of arrival (U-TDOA) in a wireless access network are generally described herein. Other embodiments may be described and claimed. In some embodiments, a first timing adjustment is determined from receipt of the ranging frame from the mobile station within the granted uplink time-slot, and a second timing adjustment is received from the non-serving base station. The second timing adjustment may be determined by the non-serving base station based on receipt of a ranging frame from the mobile station.
