BEAM ADAPTATION FOR RECONFIGURABLE INTELLIGENT SURFACE AIDED UE POSITIONING

Abstract

Aspects presented herein may improve the performance and accuracy of a UE positioning based on RIS, such as when the RIS has a limited number of control voltage sets available. In one aspect, a UE obtains an indication of beam pattern information for a set of DL beams for a network entity, where the set of DL beams is associated with an RIS. The UE adjusts a first transmission angle for a set of UL beams based on the beam pattern information and measurement for the set of DL beams, where the first transmission angle for the set of UL beams is adjusted to proximately align with a second transmission angle of the set of DL beams from the RIS. The UE transmits, via the RIS, the set of UL beams to the network entity based on the adjusted first transmission angle.
