1. A method of wireless communication performed by a user equipment (UE), comprising:
receiving, from a positioning entity, assistance data for enabling the UE to estimate a location of the UE, the assistance data including a relative location of each of a plurality of transmission points, wherein the relative location of each of the plurality of transmission points is represented by coordinates of a fixed reference point and a plurality of vectors, wherein the plurality of vectors define two or more levels of description, wherein, for each transmission point, a first level of description of the two or more levels of description represents a location of a transmission-reception point (TRP) relative to the fixed reference point, and a second level of description of the two or more levels of description represents a location corresponding to a positioning reference signal (PRS) resource set relative to the location corresponding to the TRP;
estimating the location of the UE based on characteristics of reception of at least one positioning reference signal from each of a subset of the plurality of transmission points and the plurality of vectors and the fixed reference point for each of the subset of the plurality of transmission points.
