About Carrier aggregation

It's a used in wireless communication to increase the data rate per user, whereby multiple frequency blocks assigned to the same user.

Types

1) intra-band contiguous (same frequency band)

2)intra-band non-contiguous (same frequency band but are separated by a gap the carrier aggregation)

3) inter-band carrier aggregation (different frequency band)

Application and support

HSPA+/UMTS

The chanel bandwidth for UMTS/HSPA+ is about 3.8 MHz with a carrier spacing of 5 MHz. Carrier aggregation is also called Dual Cell in the context of UMTS/HSPA+.

LTE and advanced

LTE supports since its first release channel bandwidths of 1.4 MHz, 3 MHz, 5 MHz, 10 MHz, 15 MHz and 20 MHz.

More about CA

Three CA configurations are defined

Type of CA and duplex type	CA configuration	Maximum aggregated bandwidth (MHz)	Max number of CC
Intra-band contiguous FDD	CA_1C	40	2
Intra-band contiguous TDD	CA_40C	40	2
Inter-band FDD	CA_1A_5A	20	1 + 1
