  Abstract

RT (Ray Tracing) models are widely used in RAN for channel modelling. Another possible application in processing chain of base station with multiple purposes: positioning, channel estimation/prediction, radio resources scheduling and others. In this paper RT positioning technique is addressed for Urban Outdoor scenario. Proposed robust approach achieves several meters accuracy even in NLOS and multipath conditions. Developed RT tracking was used for multiuser (MU) precoder prediction and demonstrated significant capacity gain. Also, this paper discloses practical aspects for achieving high accuracy.
