5G-NR New Radio (5G-NR) is destined to revolutionize the wireless communications as well as user wireless positioning. 5G-NR will be able to offer not only higher throughput and higher available frequency bands of operation, but also improved services, including enhanced Location Based Services. 5G systems will continue to use the Positioning Reference Signals (PRS) employed now in 4G systems, in order to enable positioning with non-synchronized Base Stations (BS) with an increased performance compared to 4G positioning. PRS are used to measure the delays of the downlink transmissions by correlating the received signal from the base station with a local replica in the receiver. In this paper, different PRS allocations within the 5G frame are analysed and compared in order to find if the PRS distribution affects the positioning performance, and, if this happens, which the best distribution is.
