tectures would combine several bands into a single transceiver chain, independent of radio access technology. The RF front-end subsystem comprises PAs, filters, duplexers, switches, oscillators, mixers, LNAs and other passive and active RF components that enable the device to conform to 3GPP and regional regulatory emission specifications. It is understood that various OEMs may combine RF front-end components in different groupings depending on component selec- tion and functionality provided by those components for carrier aggregation and multi- connectivity purposes. Various architectures combine mid-frequency bands (1.7-2.1 GHz and 2.3-2.7 GHz) into a single module to simplify the implementation of carrier aggrega- tion. Similarly, high-frequency bands (in sub-6 GHz) can be combined with Wi-Fi and share antennas. Due to different transmit/receive configurations (e.g., antenna configurations), network deployments, and different downlink and uplink transmit power, the LTE coverage in general was limited in the uplink. According to the evaluation done for LTE Band 41 Power Class 2 (+ 26 dBm), the coverage asymmetry could be up to 5 dB based on the network deployment parameters. To improve the uplink coverage, an effective way is to increase the transmit power. Based on some initial analysis of the NR link budget, it appeares that it would suffer from the same issue. Therefore, operators proposed to specify Power Class 2 (+26 dBm) and Power Class 3 (+23 dBm) UE in 3GPP RAN Working Group 4 [2,25]. In contrast to the NR BS, the UE implementations utilize beamforming in FR2 and the RF front-end configurations in FR1 are not significantly different from LTE UEs except in the new 3.7 and 4.5 GHz band implementations. The early deployments of NR use non- standalone mode, thus the compliant UEs will have to implement both LTE and NR radio transceivers. In FR1, the RF performance is specified for the new radio parameters such as the maximum transmit power and receiver sensitivity. In this frequency range, the con- ducted
