Configuration of non-contiguous carrier aggregation intra-band The Release R.16 specification is limited aggregation class A configurations. NG-RAN and 5G-NR 5.2.1.4. Inter-band carrier aggregation The possible band combinations for the inter-band configuration are described in 3GPP TS 38.101-1 V16-4-0 specifications: - 79 possible aggregations of two inter-band channels in the FR1 band (Table 5.2A.2.1-1); - 35 possible aggregations of three inter-band channels in the FR1 band (Table 5.2A.2.2-1); - six possible aggregations of four inter-band channels in the FR1 band (Table 5.2A.2.3-1). Table 5.6 gives an example of aggregation on two bands, n77 and n79. Figure 5.4 illustrates the n77A_n79A configuration. NR CA configuration (kHz) CA_n77A- Table 5.6. Inter-band carrier aggregation 5.2.2. Carrier aggregation in the FR2 band 5.2.2.1. Carrier aggregation class For the FR2 band and according to Release 16, the radio bandwidth class categories are defined in Table 5.7. Class A corresponds to a 5G-NR configuration without carrier aggregation. The maximum 5G carrier band (BWChannel, max) depends on the band number and
