Abstract
Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) applies a plurality of positioning reference signal (PRS) processing windows to a PRS resource received from a network node over a multipath channel, determines a plurality of channel estimates for the PRS resource based on the plurality of PRS processing windows, and determines a positioning measurement of the PRS resource based on the plurality of channel estimates.
Claims30
A method of wireless communication performed by a user equipment (UE), comprising:
- applying a plurality of positioning reference signal (PRS) processing windows to a PRS resource received from a network node over a multipath channel, wherein the plurality of PRS processing windows is determined based on application of a corresponding plurality of frequency domain pulse-shaping filters to the PRS resource, and wherein each frequency domain pulse-shaping filter of the plurality of frequency domain pulse-shaping filters uses different limits on excess bandwidth of the frequency domain pulse-shaping filter compared to remaining frequency domain pulse-shaping filters of the plurality of frequency domain pulse-shaping filters;
- determining a plurality of channel estimates for the PRS resource based on the plurality of PRS processing windows;
- determining a plurality of features of the PRS resource based on the plurality of channel estimates;
- and
- determining a positioning measurement of the PRS resource based on the plurality of features.
