Nokia Solutions Networks continues its thought leadership in TD-LTE at the recent Global TD-LTE Initiative (GTI) workshop in Bangkok. By driving the innovation in TD-LTE for 1000x capacity, NSN aims to make TD-LTE one of the leading technologies for 4G mobile broadband and beyond.
The Bangkok workshop was the eighth in a series of global workshops and covered topics such as TDD-FDD convergence, multiple antenna technologies and VoLTE. As a member of the GTI Partner Forum, NSN continued its strong participation with speakers Kenny Steele, Jingxiu Liu, and Asha Hemrajani presenting TDD-FDD Convergence, Beamforming Evolution, and LSA (Licensed Shared Access) Beyond 4G – all topics on meeting 1000x capacity using TD-LTE.
Jingxiu Liu described the evolution of NSN’s beamforming techniques and its applications: “NSN has pioneered the implementation and testing of transmit mode 9 (TM9) single stream and dual stream beamforming for 8 antenna TD-LTE networks using its commercial Flexi Multiradio 10 Base Station. This is exceptional because it multiplies the download throughput significantly compared with today’s 2 transmit MIMO (multiple input multiple output) techniques. These extensive simulations and field tests show that TM9 is certainly a better choice for operators.”
In a nutshell, TM9 allows the base station and user device to estimate the optimal traffic beam. It promises a dramatic increase in capacity and is certainly a step towards 1000x capacity using TD-LTE.
Kenny Steele highlighted an exciting opportunity for TDD-FDD coexistence based on our experience with many commercial TDD-FDD LTE networks: “The ideal operator strategy for TDD-FDD commercial networks should include the technical design, challenges and solutions to ensure smooth integration. Coexistence of TDD-FDD networks is now in the accelerated stage and is boosting TD-LTE global promotion.”
Asha Hemrajani presented on topics beyond LTE-Advanced and beyond 4G of LSA (Licensed Shared Access): “In the near future, even today’s spare TD-LTE spectrum will not be sufficient. So NSN is investing in ‘beyond 4G’ techniques like LSA and Authorized Shared Access (ASA) that allow smooth and dynamic use of unused spectrum and thus increase capacity.”
All of these TD-LTE advances are important ingredients to the recipe for achieving 1000x capacity.
