Abstract

Techniques for wireless communication are disclosed. In an aspect, a wireless communication device may receive or transmit sidelink positioning control information specifying an index of a set of candidate sidelink positioning reference signal (SL-PRS) parameters selected from one or more candidate sets of SL-PRS parameters, each of the one or more candidate SL-PRS parameter sets indicates one or more parameters for the SL-PRS. The wireless communication device may receive or transmit an SL-PRS transmission for a sidelink positioning session based on the selected set of SL-PRS parameters.
