TLDR
A new flexible time division duplexing based radio interface for future 5G small cell communications to achieve high energy efficiency, high spectral efficiency and low latency at the same time is introduced.Abstract:
In this paper we introduce a new flexible time division duplexing based radio interface for future 5G small cell communications. We describe the benefits of the new design to achieve high energy efficiency, high spectral efficiency and low latency at the same time. We also compare our reference design against LTE-A assuming rank 8 DL SU-MIMO transmission and show that we our design can achieve more than 29% lower total overhead and up to 90% lower round trip time.read more
