Performance analysis of inter-band and intra-band carrier aggregation on planning and dimensioning LTE-Advanced in bandung city

Carrier Aggregation (CA) is ones of LTE-Advanced features, which can increase transmission bandwidth capacity by aggregating Component Carriers (CCs). The increment of bandwidth capacity depend to numbers of CCs aggregations. It can be two or more CCs aggregation, arranged by 3rd Generation Partnership Project (3GPP). There are intra-band CA and inter-band CA. Intra-band CA divided in two: intra-band contiguous CA and intra-band non-contiguous CA. This research aim to analysis the effect of CA and types of CA which can be optimum in Bandung city. Research start from planning and dimensioning LTE-Advanced radio access network in Bandung area using Atoll software. The scenario bandwidth configuration of CA maximum is 40 MHz and using two CCs by using frequency 1800 MHz and 2100 MHz. Simulation result show the network covered 100% of high speed internet user on simulation area. CA increase RSRP around 3 dB and decrease BLER around 0.02-0.07 %. Inter-band CA with PCell 1800 MHz and total bandwidth 40 MHz has the best mean throughput (43.35 Mbps).
