5G-oriented Terminal and Chipset Technology White Paper

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.
