Digital transformation is indispensable for achieving sustainable development, and deployment of
fifth-generation wireless networks (5G) is instrumental for making digital transformation a reality.
There are a number of challenges and technical choices that influence 5G deployment with impacts
on efficiency, interoperability, and associated costs. These are of significant importance as there
is no roadmap that would be universally applicable to all network operators for deploying 5G and
beyond. In this paper, we contextualize various technical options for 5G deployment and discuss
their impacts. Specifically, we focus on the timely utilization of various standards pertaining to
radio access network (RAN), transport network (TN), and core network (CN) with a view to
enhancing interoperability with existing networks/facilities. We also discuss how 5G standards are
evolving.

5G mobile networks are envisioned to support both evolved mobile broadband (eMBB) and ultra-
reliable and low latency communications (URLLC), which may coexist and interfere with each
other in the same service cell in many scenarios. In this paper, we propose a dynamic 2-dimension
bitmap resource indication to cancel eMBB services with a finer uplink cancellation granularity
and a lower probability of false cancellation. Meanwhile, a resource indication based power
control method is introduced to dynamically indicate different power control parameters to the
user equipment (UE) based on different time-frequency resource groups and the proportion of
overlapping resources, by which the reliability of URLLC transmission is guaranteed while the
impact on performance of the eMBB service is minimized. Furthermore, a dynamic selection
mechanism is proposed to accommodate the varying cases in different scenarios. Extensive system
level simulations are conducted and the simulation results show that about 10.54% more URLLC
UEs satisfy the requirements, and the user perceived throughput of eMBB UEs is increased by
23.26%.

The industrial Internet of things (IIoT) is an important engine for manufacturing enterprises to
provide intelligent products and services. The data analysis model represented by digital twins is
the core of IIoT development in the manufacturing industry. With the development of IIoT, more
and more attention has been paid to the application of ultra-reliable and low latency
communications (URLLC) in the field of IIoT. This paper mainly introduces the development of
3GPP for URLLC in reducing delay and enhancing reliability, as well as the research on little jitter
and high transmission efficiency, and further analyzes the enhanced key technologies required in
the IIoT. Finally, the application of IIoT in digital twins is analyzed according to the actual
situation.
