WebIntroduction. The 3GPP 5G NR standard defines sets of link and waveform configurations for the purposes of conformance testing. Two specific types of downlink conformance waveforms are NR test models (NR-TM), for the purpose of base station (BS) RF testing, and downlink fixed reference channels (FRC), for user equipment (UE) input testing. WebIn order to enable this, there is one downlink reference signal transmitted from each antenna port, as illustrated in Figure below. In case of two transmit antennas ports, (left part of Figure above), the position of the …
