1. A method performed by a user equipment (UE), the method comprising:
obtaining sensor data comprising first radio frequency (RF) ranging data and imaging data;
tagging the first RF ranging data with location information and semantic information, wherein the semantic information is based on the imaging data, and wherein the semantic information indicates a first portion of the RF ranging data is associated with a static object type and a second portion of the RF ranging data is associated with a temporary-static object type different from the static object type; and
transmitting, to a RF ranging assistance server, the first RF ranging data tagged with the location information and the semantic information.
