How is carrier aggregation used in inter-band carrier aggregation?


Asked by Joyce Norman on Nov 28, 2021 FAQ



In the case of inter-band carrier aggregation the component carriers will experience different pathloss, which increases with increasing frequency. In the example shown in figure 3 carrier aggregation on all three component carriers can only be used for the black UE, the white UE is not within the coverage area of the red component carrier.
Subsequently,
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.
Indeed, Inter-band non-contiguous: This form of carrier aggregation uses different bands. It will be of particular use because of the fragmentation of bands - some of which are only 10 MHz wide. For the UE it requires the use of multiple transceivers within the single item, with the usual impact on cost, performance and power.
Consequently,
LTE Carrier Aggregation Bandwidth Classes Carrier Aggregation Bandwidth Class Aggregated Transmission BW Configuration Number of component carriers A ≤100 1 B ≤100 2 C 100 - 200 2
Just so,
The CCs can be of different bandwidths. Each aggregated carrier is referred to as a component carrier, CC. The component carrier can have a bandwidth of 1.4, 3, 5, 10, 15 or 20 MHz and a maximum of five component carriers can be aggregated, hence the maximum aggregated bandwidth is 100 MHz.
