Abstract

See full text

The angle of departure (AOD) of directed beams, e.g., beamformed beams, transmitted by one or more base stations, such as a gNB, and the angle of arrival (AOA) of the directed beams received by a UE may be used to improve positioning accuracy by identifying Line Of Sight (LOS) beams and multi-path beams. The differential AOA (DAOA) of a directed beam pair may compared to the differential AOD (DAOD) of the directed beam pair. Matching DAOA and DAOD may be used as an indication that the directed beams in the beam pair are LOS with the UE, whereas a mis-match indicates one or both of the directed beams are multi-path. The location of the UE may be estimated using the measurement information, e.g., AOA, RTT, RSTD, etc., obtained from LOS directed beams.
