ions will incorporate additional bands. Using a release-independent principle, it is possible to design devices based on an early release of 3GPP specifications that support a frequency band added in a later release. The first set of NR bands is defined in 3GPP Rel-15, and additional bands will be added in a release-independent manner. The NR can operate over a wide range of frequencies which include sub-6 GHz and above 6 GHz spectrum. The support of this extremely wide range of frequencies implies that the radio characteristics and operating parameters can significantly vary depending on the fre- quency band and the operating bandwidth; thus it is desirable to be able to configure the radio-related parameters such as subcarrier spacing, OFDM symbol length, cyclic prefix length, channel bandwidth according to the allocated frequency band. The NR specifies two frequency ranges, namely, FR1 and FR2 where each support certain OFDM numerologies. In FR1, which covers 450 MHz to 6 GHz, the subcarrier spacings that can be used for data transmission are 15, 30, and 60 kHz. The FR2 supports subcarrier spacings of 60 and 120 kHz. The UEs are required to support all subcarrier spacings except 60 kHz in FR1. The ratio of cyclic prefix length over OFDM symbol length is the same for all supported subcarrier spacings. Therefore, as the subcarrier spacing increases, the cyclic prefix length decreases, resulting in more susceptibility of NR signals to multipath delay distortion and coverage reduction. The use of larger subcarrier spacings further increases the NR signal tolerance to Doppler shift. It must be noted that the effect of oscillator phase noise is more pronounced in FR2 bands, resulting in inter-carrier interference. The use of larger subcarrier spacing helps mitigate the effects of phase noise. The subcarrier spacing is configured by New Radio Access RF and Transceiver Design Considerations 659 the network using higher layer signaling. The most appropriate subcarrier spacing can be configured according to the deployme
