2 dB and the UE RF noise figure 7 dB. The base station output power is 200 W (53 dBm) and the device power 0.4 (26 dBm) for TDD and 0.2 W (23 dBm) for FDD. The downlink share in TDD is assumed to be 80% and for the uplink 20%. If the 1 Mbps PUSCH data rate is required, the instantaneous data rate must be 5 Mbps during the uplink part. That explains why the PUSCH is the limiting factor for the coverage. The PDSCH and PUSCH SNR requirements are taken from Shannon theory with a 4 dB margin. It is further assumed that uplink 2RX gives a 3 dB gain and downlink 4RX gives a 4 dB gain. In theory, 4RX could provide more gain, but designing four antennas in the small form factor in the device is challenging. We assume 10 5G Performance that the PUSCH bandwidth (number of physical resource blocks [PRBs]) is large enough SO that Quadrature Phase Shift Keying (QPSK) modulation can be used. The PDSCH transmission is assumed to use a maximum of 50% of the downlink PRBs, which corresponds to two simultaneous UEs in the downlink sharing power equally. A long PUCCH format with 30 kHz is assumed with an SNR requirement of -6 dB. A long PRACH sequence with 30 kHz and three PRBs is assumed with an SNR requirement of -10 dB. The Sounding Reference Signal (SRS) is assumed to have a low bandwidth of four PRBs. SRS transmission has flexibility between uplink signaling and downlink beam- forming quality. Wideband SRS provides better quality for the downlink beamform- ing. Narrowband SRS has greater coverage while providing lower quality estimates for the beamforming. We assume that the SNR requirement for SRS is -10 dB. The SRS must be received with each receiver branch separately, which does not give beam- forming gain. Therefore, the antenna gain for the SRS is lower than for other channels. The calculation assumes a 16 dBi gain for SRS reception. The PDCCH SNR requirement is assumed as -6 dB, and the transmission uses 24 PRBs with an aggregation level of four. The PBCH SNR requirement is assumed as -10 dB, and the transmission uses 20
