the actual requirements; instead, there is a reference to the applicable LTE (TS 36.101), 5G FR1 38.101-1), or 5G FR2 (TS 38.101-2) specification. A big part of TS 38.101-3 is just listing what are the specified 5G CA, EN-DC, NE-DC, or NR-DC configurations that can be deployed. TS 38.101-4 include UE requirements for demodulation performance and channel state information (CSI) reporting for both FR1 and FR2. 12.3 5G Standalone Performance Aspects in Frequency Range 1 12.3.1 New Channel Bandwidths and Improved SU As discussed in Section 12.2.1, NR has introduced a new SCS which enables larger channel bandwidths beyond the 20 MHz maximum channel bandwidth of LTE. This is important for the new spectrum available above 2.5 GHz in FR1 with bands offering more than 100 MHz total bandwidth. Instead of having to use intra-band contiguous carrier aggregation of 20 MHz channels, NR offers channel bandwidths up to 100 MHz. As can be seen from the header of Table 12.2, a large choice of channel bandwidths from 5 to 100 MHz is provided with good granularity, and the maximum number of RBs that can be allocated per channel is provided for the different SCSs valid for FR1. In FR1, valid SCSs are 15, 30, and 60 kHz. 15 kHz SCS is compatible with LTE and thus allows an easy refarming of LTE bands with NR. Higher SCS values not only enable shorter frames and improved Doppler immunity, but also higher channel bandwidths. The minimum and maximum channel bandwidths realizable for a given SCS are dic- tated by two aspects: The maximum FFT size of 4096 bins sets the maximum number of RBs and thus the maximum channel bandwidth. For 15 kHz SCS, the maximum bandwidth would be 4096 X 15 kHz = 61.44 MHz, but accounting for the margin needed for the cycle prefix, it is actually limited to 50 MHz channel bandwidth. The number of subcarriers (107) for the synchronization channel also sets the min- imum channel bandwidth that can be accessed by the UE. For 60 kHz SCS, the syn- chronization channel needs to be larger than 107 X 60 kHz = 6.42 MHz;
