ne contiguous allocated block of spectrum for transmission and reception by the same BS. The lower subblock edge of the subblock bandwidth (BW channel-block) defined as fedge-block-low = fc-block-low foffset-low. The upper subblock edge of the subblock bandwidth is defined as fedge-block-high fc-block-high -foffset-high- The subblock bandwidth channel-block is defined as BW channel-block = fedge-block-high -fedge-block-low (MHz). The lower and upper frequency offsets foffset-block-low and foffset-block-high depend on the transmission bandwidth configurations of the lowest and highest assigned edge component carriers within a subblock which are defined as foffset-block-low = (12NRB-low 1)SCSlow/2 + WGB-low (MHz) and foffset-block-high = (12NRB-high 1)SCShigh/2 + WGB-high (MHz), where NRB-low and NRB-high are the transmission bandwidth configurations for the lowest and highest assigned compo- nent carrier within a subblock, respectively. In the latter equations, SCSlow and SCShigh denote the subcarrier spacing for the lowest and highest assigned component carrier within a subblock, respectively; WGB-low and WGB-high are the minimum guard bands for the lowest and highest assigned component carriers, respectively. The subblock gap size between two consecutive subblocks Wgap is defined as Wgap = fedge-block-low(n+1) -fedge-blockn-high(n (MHz). Because the subblock gap starts from the inner edge of the channel bandwidth and not the center of the channel bandwidth, the subblock gap width is independent of the component carriers' channel bandwidth [5]. The frequency spacing between RF carriers depends on the deployment scenario, the size of the frequency block available and the BS channel bandwidths. The nominal channel 664 Chapter 5 spacing DF between two adjacent NR carriers is defined based on the frequency range and channel raster. For NR FR1 operating bands with 100 kHz channel raster, DF = (BW channel(2))/2. For NR FR1 operating bands with 15 kHz channel = FR2 operating bands with 60 kHz channel raster, DF = N chan
