1. An apparatus for allocating resources for downlink (DL) positioning reference signals (PRSs) in a wireless communication system, the apparatus comprising:
a baseband processor; and
a memory storing instructions that, when executed by the baseband processor, configure the apparatus to:
configure a DL PRS resource pool comprising a periodically repeated amount of resources dedicated for DL PRS transmission by a plurality of base stations in the wireless communication system;
divide the DL PRS resource pool into a plurality of DL PRS resource sets corresponding to one or more base station of the plurality of base stations; and
generate configured DL PRS resources within the plurality of DL PRS resource sets for transmission of the DL PRSs, wherein the configured DL PRS resources comprise a resource element map pattern based on N consecutive symbols comprising comb-N frequency allocation patterns corresponding to unique frequency shifts, wherein a value of N={1,2,3,4}.
