UE reference sensitivity in FR1 is defined as a power level PREFSENS = 10 log(kToWN) + NF + SINR + LIM - GDIV (dBm) where kToWN is the thermal noise power in dBm, WN is the noise equivalent bandwidth (approximately the UE bandwidth), NF is the maximum receiver noise figure, SINR is the minimum SINR for the chosen MCS, and LIM Chapter 5 Spurious emissions BW 5 MHz BW + 5 MHz Spurious emissions down to 9 kHz up to fifth harmonic or 26 GHz Uplink operating band UE RF bandwidth Spurious emissions Spurious emissions down to 30 MHz up to second harmonic Uplink operating band UE RF bandwidth BWchannel For 5-40 MHz: -13 dBm/1%CBW For 50-100 MHz: -24 dBm/30 kHz -5 dBm/ 1MHz -10 dBm/MHz -13 dBm/ 1MHz -13 dBm/MHz -25 dBm/MHz -BW-5 BW BW+5 -2CBW -CBW-10%CBW %CBWCBW NR spectrum emission mask 31 dB/30 dB NR ACLR 33 dB 36 dB For n257,n258,n261: 17 dB NR ACLR NR ACLR For n260: 16 dB BWchannel NR ACLR NR ACLR 2.5 MHz 7.5 MHz NR ACLR requirement BWchannel FR1 Out-of-Band Emission FR2 Out-of-Band Emission Figure 5.14 UE output RF spectrum and out-of-band emissions [2,3], is the implementation margin. Note that the noise floor for any receiver is defined as Noise_Floor = 10 log(kToWN) + NF = - 174 + NF + 10 logWn (dBm), where NF = SNRin - SNRout (in dB) is a measure of SINR degradation by the components in the RF signal path including the RF filters and LNA. The thermal noise power density kT = - 174 dBm/Hz is measured at typical room temperature 290 K degree. 3GPP assumes minimum SINR = 1 dB New Radio Access RF and Transceiver Design Considerations 699 for the UE, the implementation margin of LIM = 2.5 dB and a diversity gain of GDIV = 3 dB for a UE for two RX antennas. The noise figure NF is 9 dB for LTE refarming bands, 10 dB for n77 (3.3-3.8 GHz) n78, and n79 bands, and 10.5 dB for n77 (3.8-4.2 GHz) band. In FR1, both 2RX REFSENS (for all bands) and 4RX REFSENS (for n7, n38, n41, n77, n78, n79) bands are defined. In FR2, REFSENS power le
