LTE-Advanced technology (LTE-A) focuses on increasing the bandwidth of the access network by using a variety of techniques, one of which is by carrier aggregation (CA). Carrier aggregation (CA) is a technique used to create virtual bandwidth by combining 2-5 component carrier (CC) at the same or different frequency with total aggregated bandwidth reaching 100 MHz. This thesis aims to perform LTE-A network planning using FDD-TDD CA technique Rel 13 case studies in central Jakarta with area coverage probability reach 95% and RSRP &#8805; 100 dBm. Network performance analysis is based on the measurement of BLER, peak RLC throughput channel, effective channel throughput, and path loss, obtained from monte carlo simulation results in a combination of FDD-TDD Rel-13 spectrum with total aggregated bandwidth reaching 30 MHz using 2 component carrier. Research is also aimed at obtaining the best FDD-TDD spectrum combinations on E-UTRA CA band Rel-13 in order to be a reference on the next generation cellular technology system. Based on experiment and simulation result analysis on the three scenarios of FDD-TDD CA Rel 13, ie CA 8-41, CA 8-42, and CA 3-4, the writer can design LTE-Advanced access network in Central Jakarta with probability area covered reached 95% and different RSRP values in each scenario. The RSRP obtained from CA 8-41 and 8-42 scenarios with a frequency 900 MHz FDD as primary cell (Pcell), are in the range of -90 dBm or > -100 dBm and are good for dense urban areas such as Central Jakarta. While RSRP in scenario CA 3-41 with frequency 1800 MHz FDD as primary cell (Pcell), is -103 dBm or <-100 dBm and classified as bad for urban dense area. The simulation results also show that the combination of FDD-TDD CA has a quality of load-balancing, where the effectiveness of using RLC throughput channel for each service on urban cluster dense reaches 99% in the downlink direction for all scenarios. .Peak RLC highest channel throughput was obtained from the CA 3-41 scenario with a total aggregated bandwidth of 30 MHz, this indicates the number of bandwidth combinations in the LTE-Advanced network can increase the throughput value. The best FDD-TDD CA Release 13 is obtained from the FDD-TDD scenario of CA 8-41 and 8-42 because it has the smallest path loss value, where the frequency 900 MHz FDD as Pcell. This shows that low of frequency has good quality in case of coverage for dense urban areas such as case studies in Central Jakarta, compared with 1800 MHz FDD frequency in CA 3-4 scenario. The BLER on Uplink is 0 for all scenarios, it shows the connection on uplink is 100% successfull. While BLER on downlink is at 2% for all scenarios or still good category on every carrier combination because BLER value <10%.
