Method and apparatus for location finding in a wireless communication system

摘要: A method and apparatus for determining the location of a communication unit in CDMA system includes first embodiment, sending request via spread spectrum signal to subscriber (140), receiving return including response message showing receive time particular symbol base's spreading sequence transmit subscriber's sequence. The base (130), along with other base(s) also receives predetermined sequence, each determines respective symbol. received information is then processed, known delay information, determine location. If insufficient number bases are capable communicating subscriber, example due high loading/interference, auxiliary (121) provided from or transmitting subscriber.
