AI Technical Summary

Technical Problem

In existing wireless communication systems, UE-assisted positioning methods require a large amount of bandwidth to report positioning signals from multiple TRPs, resulting in excessive processing resources and power consumption, especially for battery-powered UEs.

Method used

By reducing overhead through beam profile parameterization, the UE receives an index describing the transmit antenna configuration, antenna element power mode, and precoding matrix information, rather than a complete representation. This allows the UE to look up the representation using existing information, reducing bandwidth requirements.

Benefits of technology

It significantly reduces bandwidth requirements and power consumption, and improves the efficiency of wireless communication systems and the positioning accuracy of UEs.

Abstract

Techniques for wireless communications are disclosed. In an aspect, a receiving entity receives information characterizing a set of positioning signals to be transmitted by a transmission-reception point (TRP) using a set of transmit beams, the information including at least one antenna element radiation pattern, at least one antenna element array configuration, and, for each beam of the set of transmit beams, information identifying at least one precoding matrix. The receiving entity performs measurements of the positioning signals transmitted by the TRP and computes at least one positioning measurement estimate based on at least some of the at least one antenna element radiation pattern, the at least one antenna element array configuration, the information identifying at least one precoding matrix, and the positioning measurements. The receiving entity transmits positioning information to the TRP. The positioning information can include the at least one positioning measurement estimate.
