METHOD AND APPARATUS FOR LOCATION FINDING IN A COMMUNICATION SYSTEM

A method for determining a subscriber unit location in a communication system including the steps of receiving a signal from the subscriber unit (1390) at a first base station, determining a first receive time of the signal based on a sequence of spreading symbols at the first base station, determin...

Beschreibung
Zusammenfassung:	A method for determining a subscriber unit location in a communication system including the steps of receiving a signal from the subscriber unit (1390) at a first base station, determining a first receive time of the signal based on a sequence of spreading symbols at the first base station, determining a first angle of arrival of the signal at the first base station, and determining the location of the subscriber unit from the first received time, the first angle of arrival, and further predetermined information about the first base station. The signal is formed via modulation by the sequence of spreading symbols.
