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.

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 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.
Read moreWhat is carrier aggregation and why is it used?
Carrier aggregation is a technique that is used in wireless communication to increase the data rate per user, whereby multiple frequency blocks (called component carriers) are assigned to the same user . The maximum possible data rate per user is increased the more frequency blocks are assigned to a user.
Read moreShould I turn on carrier aggregation?
Carrier Aggregation in smartphones helps offer more bandwidth and faster data speeds by combining different network bands . It’s usually present on most modern mid and high-priced smartphones and could be a deal-breaker for people buying a smartphone.
Read moreWhat is 4G LTE CA?
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.
