Carrier aggregation class on band FR1 Carrier aggregation configuration includes: - the type of carrier aggregation (intra-band, contiguous or not or inter-band); - the number(s) of the 5G bands; - the bandwidth class with the possible bandwidths on each CC. 5.2.1.2. Contiguous intra-band carrier aggregation For the FR1 band, Release R.16 proposes 10 aggregation schemes of contiguous intra-band carriers (Table 5.2). Table 5.3 lists non-exhaustive combinations of contiguous intra-band carrier aggregation for bands n7 and n77 and for classes B, C and D. Figure 5.4 illustrates the n77C configuration.
