Toni Levanen, Juho Pirskanen and Mikko Valkama, "Radio interface design for ultra-low latency millimeter-wave communications in 5G Era," Proceedings of IEEE Global Communications Conference (GLOBECOM 2014), Austin, TX, December 2014, pp. 1420–1426.


The projected growth of mobile data traffic requires the 5G wireless systems to support at least 1000 x larger area throughput than the existing 4G solutions. This requires ultra-dense local area networks combined with millimeter-wave communications to provide high spatial multiplexing gain and wide bandwidths for multi-gigabit peak data rates. In this paper, we extend our 5GETLA reference design for 5G small cell network radio interface in 3-10 GHz carrier frequencies towards millimeter-wave communications and discuss separate solutions for both line-of-sight and non-line-of-sight scenarios. The non-line-of-sight frame design achieves frame duration equal to 0.1 ms which is one hundredth of the LTE frame duration. The line-of-sight design is also considered as a good candidate especially for small-distance indoor wireless access or inband backhaul and is particularly optimized in terms of ultra-low latency with frame duration equal to 0.05 ms, achieving the strictest physical layer latency requirements set for 5G communications.
