Carrier aggregation

CA configuration: indicates a combination of E-UTRA operating band(s) and CA bandwidth class(es) , to exemplify the configuration CA_1C indicates intra-band contiguous CA on E-UTRA operating band 1 and CA bandwidth class C, CA_1A_1A, indicates intra-band non-contiguous CA on band 1 with a one CC on each side of the …

LTE Advanced Carrier Aggregation, CA, is one of the key techniques used to enable the very high data rates of 4G to be achieved . By combining more than one carrier together, either in the same or different bands it is possible to increase the bandwidth available and in this way increase the capacity of the link.

Carrier Aggregation (CA) is a technique used in LTE-Advanced to increase the peak data rate (i.e., maximum available speed) of a 4G LTE network .
