A successful verification of LTE FDD three component carrier (3CC) aggregation in the downlink, including 4x4 MIMO on each carrier has been completed by Rohde & Schwarz and Prism Telecom Testing. The companies will present the test setup to the public for the first time at Mobile World Congress in Barcelona (Feb 22-25).
The solution consists of three R&S CMW500 wideband radio communication testers, the R&S CMWC controller and the Prisma UeSIM multiterminal simulator. Each R&S CMW500 generates a component carrier with 20 MHz bandwidth and 4x4 MIMO. The entire setup is able to provide a downlink data rate of 900 Mbit/s. The Prisma UeSIM is equipped with two SDRv3 units and one eLSU unit for terminating the traffic.
The 3CC 4x4 MIMO verification marks an important milestone in the commercial evolution of LTE-Advanced. The R&S CMW500, in its R&S CMWflexx configuration, and the Prisma UeSIM are the first test platforms to offer a combined downlink carrier aggregation solution for up to three 4x4 MIMO carriers, for protocol, RF and data performance verification up to 1 Gbp/s.
At Mobile World Congress, the R&S CMWflexx 3CC 4x4 MIMO test setup will be on display at the Rohde & Schwarz booth C40 in hall 6.
At booth G41 in hall 6, Prisma Telecom Testing will showcase a downlink four component carrier aggregation (4CC) test scenario using the 3GPP Rel. 12 256QAM modulation feature. 256QAM enhances the 600 Mbit/s 3GPP Rel-10 (64QAM modulation) throughput to 800 Mbit/s.
