发明名称 Method and apparatus for correcting a measured round-trip delay time in a wireless communication system
摘要 Correction of a round-trip delay within a communication system (100) takes place by receiving an uplink communication signal (119) over uplink communication signal paths (130-132) and determining what ray was utilized by a remote unit (113) in time aligning the uplink communication signal (119). In particular, a base station (101) analyzes the uplink communication signal (119) and predicts the ray that the remote unit (113) utilized for time alignment. Once the base station (101) has determined the ray that the remote unit (113) utilized in time alignment, the base station (101) corrects any calculation of round-trip delay accordingly.
