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 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.
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 CA combination?
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 …
