ons where the spectrum blocks are used with minimal spectrum wastage. This requires carefully defined channel raster for carrier allocation. There are also a number of other spectrum blocks being considered by regulatory bodies that were not initially con- sidered by 3GPP specifications, which include 5925-7150 MHz in the United States and 5925-6425 MHz by CEPT¹ for unlicensed use as well as frequency range 64-86 GHz for extremely wideband applications [12]. Note that various parts of the 64-86 GHz range are allocated differently in different regions of the world. For instance, 64-71 GHz is set aside for unlicensed use in North America and is under consideration in CEPT (66-71 GHz); 66-76 and 81-86 GHz are under study in ITU-R as possible bands for IMT-2020 to be rat- ified during WRC-19 [12]. In general, the NR UEs do not receive or transmit using the full channel bandwidth of the gNBs, rather they can be assigned to what is referred to as bandwidth parts. While the con- cept does not have any direct RF implications, it is important to note that the gNB and the UE channel bandwidths are defined independently, and the device bandwidth capability does not have to match the gNB channel bandwidth. A unified frame structure is defined in NR that supports TDD, FDD, and half-duplex FDD operations. The duplex scheme is spe- cifically defined for each operating band. Some bands are also designated as SDL or SUL bands to be used in FDD operation. Some of the frequency bands that have been identified for NR deployment are the existing ITU-R IMT2 bands which may have already been accommodating 2G, 3G, and/or 4G [incumbent] deployments. In some regions, a number of The European Conference of Postal and Telecommunications Administrations (CEPT) was established in 1959 and is an organization where policy makers and regulators from 48 countries across Europe collaborate to harmonize telecommunication, radio spectrum, and postal regulations across Europe. The CEPT conducts its work through three autonomous business committees (E
