Query: Ultrareliable and Low-Latency Communication Techniques for Tactile
  Internet Services   This paper presents novel ultrareliable and low-latency communication (URLLC)
techniques for URLLC services, such as Tactile Internet services. Among typical
use-cases of URLLC services are tele-operation, immersive virtual reality,
cooperative automated driving, and so on. In such URLLC services, new kinds of
traffic such as haptic information including kinesthetic information and
tactile information need to be delivered in addition to high-quality video and
audio traffic in traditional multimedia services. Further, such a variety of
traffic has various characteristics in terms of packet sizes and data rates
with a variety of requirements of latency and reliability. Furthermore, some
traffic may occur in a sporadic manner but require reliable delivery of packets
of medium to large sizes within a low latency, which is not supported by
current state-of-the-art wireless communication systems and is very challenging
for future wireless communication systems. Thus, to meet such a variety of
tight traffic requirements in a wireless communication system, novel
technologies from the physical layer to the network layer need to be devised.
In this paper, some novel physical layer technologies such as waveform
multiplexing, multiple access scheme, channel code design, synchronization, and
full-duplex transmission for spectrally-efficient URLLC are introduced. In
addition, a novel performance evaluation approach, which combines a ray-tracing
tool and system-level simulation, is suggested for evaluating the performance
of the proposed schemes. Simulation results show the feasibility of the
proposed schemes providing realistic URLLC services in realistic geographical
environments, which encourages further efforts to substantiate the proposed
work.
