Acknowledgement
This 5G-oriented Terminal and Chipset Technology White Paper has been developed by China
Unicom Research Institute and China Unicom Network Technology Research Institute with
contributions from China Unicom’s 4G+ Terminal Partners. The White Paper has been delivered
by a highly committed team and using a process of open contributions and continuous dialogue
throughout the whole duration of the program.
China Unicom’s 4G+ Terminal Partners played a vital role in the delivery of the 5G-oriented
Terminal and Chipset Technology White Paper. They were engaged and discussed numerous
aspects of 4G+ terminal. The feedback given and the vision shared by those Partners were
instrumental for developing the content of the White Paper.
We would like to express our appreciation to all who contributed to the development of this White
Paper.

1. New Trends of Mobile Internet Development
1.1 Trends of Mobile Service Development
As mobile internet grows increasingly popular, there is a rapid increasing demand for more
wireless network applications. Innovative mobile network applications are quickly emerging.
Traditional industries are undergoing a remarkable transformation that involves several
upgrades to unlock huge potential.
1.1.1 Consumer Market
Consumer requirements are growing at an exponential rate. Individual and household
users require high mobile network speeds and low latency. Existing networks cannot
meet these requirements and are in series need of upgrades in order to fulfill consumer
needs in the following scenarios.
Online mobile videos are under rapid development. Video On Demand (VOD), video
on-live (VOL), internet TV programs, and mobile video sharing platforms are quickly
emerging. Video quality is improving. The standard video bit rate has increased from
720p to 1080p and will further increase to 2K and 4K ultra-high-definition (UHD).
AR and VR markets will witness accelerated development over the next five years.
AR and VR require higher network speeds than traditional videos.
Wireless to the x (WTTx) services (home broadband access provided by 4G wireless
networks) have been growing increasingly popular. International Telecommunication
Union (ITU) has defined WTTx as a new home broadband access technology. WTTx
users are online longer, have five to ten times higher monthly data of usage (DOU),
and require higher bandwidth.
The rapid popularization of smartphones drives the development of the global mobile
gaming industry. Mobile gaming has become an important type of entertainment.
With fierce competition rising within the mobile gaming industry, experience is

manifesting as a competitive differentiator for many mobile game operators. An
optimal game control experience is only possible on stable networks with low E2E
latency.
1.1.2 Verticals
According to national communications and internet strategies, traditional industries
need to be digitalized and informationalized. Traditional networks cannot adapt to
verticals, which are diversified and have ever-changing requirements. Innovative
network technologies and applications are required to fulfill the following scenarios.
As the Internet of Vehicles (IoV) develops, vehicles demand lower communication
latency, higher reliability, and higher transmission rates.
Smart manufacturing and electronic healthcare are becoming more popular in the
industrial circle and also require low latency and high network reliability. Meanwhile,
these fields call for flexible network scheduling and configuration management.
The complex and diversified demands from governments, enterprise services, future
unmanned driving, AI, and cloud services also elicit higher network requirements.
1.2 Trends of Traffic Volumes on Mobile Networks
Rich contents, rapid growth of mobile users, increasing demands for industry applications,
higher bandwidth requirements for mobile applications, and the transformation of the mobile
network traffic model will increase the subsequent volume of traffic by several times.
1. The number of mobile users is rapidly growing. Radio access technologies (RATs) are
being upgraded, significantly increasing network rates. By 2020, global mobile traffic is
expected to increase by seven-fold, and the Asia Pacific will witness the highest traffic
growth rate.
