Carrier Aggregation in 5G Technology By Integrate mmWave Range and C Band

Mobile broadband services are undergoing a period of dramatic growth causing a tremendous increase in data traffic. 5G NR extends the capabilities originally defined in NR to increase data throughput by using a combination of new technologies, like Carrier Aggregation (CA), massive Multi In- put Multi Output (MIMO) techniques, beamforming and mmwaves. CA is one of the most significant 5G features that combine multiple Component Carriers (CCs) across an available spectrum to create a wider bandwidth channel for increasing the network data throughput and overall capacity.in this paper Used the CA technique by Integrated between mmwave range and C band and analyzing the planning performance (throughput, capacity, and coverage) which includes some parameters and find out the effect of CA, by conducting radio propagation using system level simulation using Atoll, for different CA scenarios of a selected high traffic area in Tripoli city, Libya .The value of the throughput when using the carrier aggregation frequency is the best, followed by the non-carrier aggregation frequency of 28 GHz, and then at the 3.5 GHz frequency. On other hand the coverage by signal level, it is found that the value of signal level -80 dBm for CA of 76.11 % and for non-carrier aggregation with 100 MHz of 3.5 GHz is 63.16 %. when frequency 28GHz with a bandwidth of 400MHz that shows coverage is 10.38%. Also it is found that the percentage of connected user on carrier aggregation mechanism is 99.9 % and for non-carrier aggregation with a bandwidth of 100 MHz at a frequency of 3.5 GHz is 93.6%.
