62 Huawei Investment & Holding Co., Ltd.

● Achieved new breakthroughs in key theories

and scheduling algorithms for next-generation

massive Multiple Input Multiple Output (MIMO)

that are applicable to future wireless networks,

increasing edge user experienced data rates by

at least 30%.

■ AI has become a major driver of revolutionary

changes to computer architecture. In this area, we:

● Attached importance to basic research,

including both theoretical breakthroughs and

technological innovation.

● Published more than 80 papers on AI, one of

which was the only paper to win the ACL 2019

Best Long Paper award.

● Were the first to propose AdderNets in the

deep learning field, which only contains

additions and breaks the traditional framework

of massive multiplications. This new method

features software-hardware co-design and thus

can achieve high performance on computer

vision tasks and potentially save over 10 times

the current requirements in terms of energy

consumption and chip area. We have also

made the testing code of AdderNets public

to the community, aiming to explore the next

generation of AI accelerators together with

academia.

● Created the industry’s first framework of

causal structure learning in replacement of the

conventional local search method. This novel

framework is based on reinforcement learning

and can achieve state-of-the-art accuracy

on academia benchmarks. Our paper on this

framework was accepted to ICLR 2020 and

ranked first (parallel with other submissions).

● Pioneered the proposal of comprehensive

explainable AI measures based on

computational metrics, and designed novel

explainable methods from data-driven and

knowledge-driven aspects, in order to construct

complete and explainable AI benchmarks in the

industry.

● Supported the implementation of hardware

design space exploration technology with Pareto

optimizations, the first of its kind to employ the

Design Space Explorer (DSE) which boosts chip

design efficiency and performance.

Innovating and inventing to drive the industry

forward

■ Advanced Wireless Networks

Today, we have entered the 5G era and embarked

on 6G research. Huawei is exploring new directions

for 6G. To this end, we:

● Began research into the basic theories of

6G, including research into new air interface

technologies, new network architectures, and

key enabling technologies.

● Initiated extensive open collaboration projects

with other industry players and pushed the

industry to build a consensus on 6G.

■ Optical Networks

To maintain our leadership in this area, we:

● Continued efforts to push the limits of fiber

capacity and created industry-leading super-

core transmission sites, which will ensure that

fiber capacity can double every 36 months,

even in the ultra-broadband age.

● Addressed the difficulties surrounding key

technologies like high-performance optical

algorithms for long-haul transmission at data

rates of 400 Gbit/s per wavelength, high-speed

optoelectronic components, and L-band wide-

spectrum optical amplifiers, extending the

transmission distance to more than 1,600 km

and increasing the capacity of a single fiber to

48 Tbit/s.

● Proposed an optical cross-connect (OXC)

architecture that supports wavelength-based

flexible scalability to a super large capacity of

10 Pbit/s.

■ Intelligent O&M

In this area, we:

● Reduced repeated work order assignment

by using intelligent identification and more

accurate fault location to ensure only a single

work order is placed for each fault.
