USER DEVICE, WIRELESS POSITIONING METHOD PERFORMED BY USER DEVICE

Abstract

The invention proposes wireless positioning techniques, specifically a user equipment and a method of wireless positioning implemented by the user equipment. In one respect, the user equipment (UE) receives a set of antenna parameters for multiple antenna ports of the transmission-reception point (TRP), obtains the positioning measurements of multiple positioning reference signal (PRS) resources transmitted on multiple antenna ports, reconstructs the physical base channel between the TRP and the UE based on the positioning measurements of the multiple PRS resources, and determines the downlink angle of arrival (DL-AoD) from the TRP to the UE based on the reconstructed physical base channel.
