Low latency radio interface for 5G flexible TDD local area communications

This paper presents a low latency radio interface design for future 5G local area communications that provides transmission latencies less than 1 ms while providing sufficient spectral efficiency. We concentrate on the excellent latency aspects of the proposed 5GETLA radio interface and discuss the factors leading to very low latency and high energy efficiency. In addition, we study two different radio interface parameterizations and compare their total overheads and achievable transmission times.
