A primary component carrier (PCC) is complemented with one or several secondary component carriers (SCC) . The PCC handles all the control signaling while the SCC is used to increase the data throughput. The carriers can be FDD, TDD or a mix of FDD and TDD with location in one or multiple frequency bands.
Read moreWhat is PCell and SCell in LTE?
The configured multiple serving cells (primary cell (PCell) and secondary cell (SCell)) are aggregated together to serve the UE . The PCell perform random access (RA) procedure, radio link monitoring (RLM), handover procedure and PUCCH transmission.
Read moreWhat is CA band class?
CA Bandwidth Class Definition It means that total aggregated RB should be less than 100 . Following shows some example cases which is allowed and not allowed configuration. Case 1 : PCC = 10 Mhz (max 50 RB), SCC = 10 Mhz (max 50 RB). It would give max aggregated RB is 50 RB +50 RB which is <= 100. So this is allowed.
Read moreHow many carriers can be aggregated in LTE?
Since LTE Release 10 up to 5 component carriers may be aggregated, allowing for transmission bandwidths of up to 100 MHz. Using five aggregated component carriers, MIMO and 256QAM allows theoretical data rates of up to 2 gigabits per second.
Read moreHow many types of carrier aggregation are there?
As mentioned earlier, there are two types of carrier aggregation: contiguous; and non-contiguous. Non-contiguous carrier aggregation can be in the form of intra-band or inter-band. The different types of carrier aggregation will result in different deployment scenarios.
Read moreWhat is 2CA and 3CA?
If you aggregate two component carriers then it will be 2CA . Whereas, if there are three or four carriers – then it is 3CA or 4CA respectively. The more the component carriers, the better will be the data speed. Types of CA. However, the most common one is wireless communication.

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 …
