Abstract
Disclosed are techniques for wireless communication. In an aspect, a first communication node (e.g., UE, BS, etc.) obtains one or more measurements associated with one or more PRSs (e.g., uplink PRS(s), downlink PRS(s), etc.) The first communication node transmits, to a second communication node (e.g., UE, BS, etc.) via L1 or L2 signaling, a report based on the one or more measurements. The second communication node receives the report and performs a position computing function based on the report.
