Ultra-Reliable and Low-Latency Communications (URLLC) Theory and
Practice Comprehensive resource presenting important recent
advances in wireless communications for URLLC services, including
device-to-device communication, multi-connectivity, and more
Ultra-Reliable and Low-Latency Communications (URLLC) Theory and
Practice discusses the typical scenarios, possible solutions, and
state-of-the-art techniques that enable URLLC in different
perspectives from the physical layer to higher-level approaches,
aiming to tackle URLLC’s challenges with both theoretical and
practical approaches, which bridges the lacuna between theory and
practice. With long-term contributions to the development of future
wireless networks, the text systematically presents a thorough
study of the novel and innovative paradigm of URLLC; basic
requirements are covered, along with essential definitions,
state-of-the-art technologies, and promising research directions of
URLLC. To aid in reader comprehension, tables, figures, design
schematics, and examples are provided to illustrate abstract
engineering concepts and make the text more accessible to a broader
readership, and corresponding case studies are included in the last
part of the book. Fundamental problems in URLLC, including
designing building blocks for URLLC, radio resource management in
URLLC, resource optimization, network availability guarantee, and
coexisting with other future mobile networks, are also discussed.
In Ultra-Reliable and Low-Latency Communications (URLLC) Theory and
Practice, readers can expect to find detailed information on: BCH
and analog codes, stable matching, OFDM demodulation and turbo
coding, and semi-blind receivers for URLLC MIMO-NOMA with URLLC,

learning for URLLC, Energy-Latency tradeoff in URLLC, and Downlink
transmission for URLLC under physical layer aspects Resource
allocation for multi-user downlink URLLC, HARQ optimization for 5G
URLLC, and Multi-Access edge computing with URLLC A unique resource
with comprehensive yet accessible coverage of a complicated
subject, Ultra-Reliable and Low-Latency Communications (URLLC)
Theory and Practice is an ideal resource for a large and diverse
population of researchers and practitioners in engineering,
computer scientists, and senior undergraduate and graduate students
in related programs of study.
This brief explores the utilization of large antenna arrays in
massive multiple-input-multiple-output (MIMO) for both interference
suppression, where it can improve cell-edge user rates, and for
wireless backhaul in small cell networks, where macro base stations
can forward data to small access points in an energy efficient way.
Massive MIMO is deemed as a critical technology for next generation
wireless technology. By deploying an antenna array that has active
elements in excess of the number of users, massive MIMO not only
provides tremendous diversity gain but also powers new aspects for
network design to improve performance. This brief investigates a
better utilization of the excessive spatial dimensions to improve
network performance. It combines random matrix theory and
stochastic geometry to develop an analytical framework that
accounts for all the key features of a network, including number of
antenna array, base station density, inter-cell interference,
random base station deployment, and network traffic load. The
authors explore the impact from different network parameters
through numerical analysis.Researchers in wireless network design
will find this to be an exceptional resource, as will
advanced-level students or professionals working in networking and
information systems design.
