Comparative Analysis of TDD Frame Structure Technology LTE-Advanced (A Case Study in Cibitung Area Indonesia)
Abstract
Based on the results of the drive-test, it showed that 72.22% of the Gramapuri Tamansari Cibitung area had downlink throughput quality below the standard of Key Performance Indicator (KPI) parameter, which was less than 8 Mbps. In addition, based on the Operation and Support System (OSS) data, in this area, the value of Physical Resource Block (PRB) utilization reached 83.93%; thus, an additional capacity from the downlink was needed. This study aims to compare Time Division Duplexing (TDD) frame structure and Inter-Band Carrier Aggregation FDD-TDD method in the Cibitung area, with band 3 FDD 1800 MHz and band 40 TDD 2300 MHz by simulation using Atoll 3.3 software. The parameters measured are downlink throughput, uplink throughput, RSRP, SINR, and connected user. The simulation results showed improving downlink throughput by 63%, uplink throughput by 65%, and connected users by 4%.
Keywords: LTE, inter-band carrier aggregation, capacity, Time Division Duplexing frame structure.
