1. A method of wireless communication performed by a positioning entity, comprising:
receiving a beam report from a network entity, the beam report including beam shape assistance information for one or more downlink transmit beams of a base station, the one or more downlink transmit beams corresponding to positioning reference signal resources to be measured by a user equipment (UE), the beam shape assistance information indicating at least one basis function representing a beam shape of each of the one or more downlink transmit beams or a quantization of a reduced portion of each of the one or more downlink transmit beams; and
determining a location of the UE based at least on signal strength measurements of the positioning reference signal resources and the beam shape assistance information.
