At the 2018 World Mobile Congress Shanghai (MWCS 2018) main forum, Xu Zhijun, the rotating chairman of Huawei, delivered a keynote speech "Let 5G Push MBB to New Heights".
He believes that 5G can enable the mobile Internet and push the mobile broadband industry to new heights; and pointed out that the development of 5G should focus on reducing OPEX as a strategic focus.
Xu Zhijun also introduced the detailed timetable for 5G products to the month ---Huawei will launch a full set of 5G commercial network solutions based on non-independent networking (NSA) on September 30, 2018; it will be launched on March 30, 2019 5G commercial system based on independent networking (SA); Kirin chips supporting 5G will be launched in 2019, and smartphones supporting 5G will be launched in June 2019.
The following is the full text of Xu Zhijun's speech:
Global collaboration, decades of sharpening a sword, the first 5G standard R15 was officially born
At 11:18 on June 14, 2018, the 3GPP plenary approved the freezing of 5G NR independent networking functions, marking the official birth of the first 5G standard, R15. Coupled with the non-independent networking NR standard completed in December last year, 5G has completed the first phase of full-function standardization. R15 mainly focuses on the commercial needs of enhanced mobile broadband, while facing the basic needs of low-latency, multi-connection services. In a 100MHz bandwidth, 5G can achieve a peak rate of 10Gbps, and a 200MHz bandwidth can achieve a peak rate of 20Gbps. It can be predicted that 5G will push MBB mobile broadband services to new heights. I would like to pay tribute to all the experts involved in 5G technology research and development and standard establishment around the world, and thank them for their hard work.
The 3GPP R15 version focuses on improving the mobile Internet experience. By the end of 2019, 3GPP R16 and later versions will completely solve the problems of massive connections and low latency, and undertake the historical mission of digitalization in all walks of life.
The various technologies adopted by 5G, such as LDPC and Polar codes, are the result of unremitting efforts of generations of basic research scientists over the past few decades. The LDPC code was proposed by American professor Robert Gallager in 1963, 45 years ago. The Polar code was proposed by Professor Erdal Arikan of Bilkeng University in Turkey in 2008, and it has been 10 years since. The birth of the 5G standard is the result of the global collaboration of various organizations and the joint efforts of several decades.
5G is the inheritance and development of 4G
Compared with 4G, 5G has faster speed, lower latency, and more connections. But from the perspective of architecture and protocol stack, 5G is the inheritance and development of 4G. Because 5G uses the same network architecture as 4G, the BBU is still the same BBU, and the RRU is still the same RRU. The protocol is basically the same, and the main thing running in the pipeline is also the mobile Internet service. Due to the introduction of stronger encryption algorithms, privacy protection and authentication mechanisms, security mechanisms have become stronger. In other words, 5G is more secure than 4G.
Standard patent licensing complies with FRAND principles
Huawei has issued a statement on May 15, 2018, stating that Huawei, as the main contributor and patent holder of the 5G standard, will continue to abide by the FRAND principle as always. Huawei is willing to continue to recommend and share more innovative technologies to industry chain partners in standardization activities, never blackmail any other company or society, and jointly build a healthy 5G ecological environment through open and equal cooperation.
Here, we will never blackmail any other company or society, which means that Huawei will strictly abide by the FRAND principle and reduce the 5G patent license fee as much as possible. At the same time, it has been advocating and promoting other rights holders who are committed to the implementation of 5G technology to make the cumulative patent fee rate lower and more transparent than 4G.
Because 5G will support the connection of 100 billion cellular devices, far more than 2/3/4G. Due to the increase in the base, even a lower IPR rate is sufficient to ensure a reasonable return on the R&D investment of standard developers.
Looking forward to 5G pushing MBB to new heights
In the 40 years of mobile communication, two major basic services have actually been formed: mobile voice and mobile Internet (especially mobile video). After about 30 years of 1G, 2G, and 3G, mobile voice has basically met the needs of users. Need to use and easy to use. The mobile Internet, especially mobile video, has not reached the height of mobile voice development from the beginning of 3G to the rapid development of 4G. We expect that 5G will enable mobile Internet, especially mobile video, to reach the height of mobile voice development today, so that users can use it. It is easy to use and easy to use. At the same time, it is expected that 5G can cultivate new basic services, such as mobile AR/VR.
Users need faster speed
The first 5G standard focuses on enhancing mobile broadband, which meets the urgent needs of users. This can be clearly felt from the latest developments in the global market.
The DOU of 4G users in the Chinese market: China Unicom has reached 9GB; China Mobile has reached nearly 5GB and is expected to increase by 3 times in the next year; China Telecom has reached nearly 7GB. Kuwait's DOU reached 70GB, Saudi Arabia's DOU 35GB; Finland increased by 43% within a year, reaching 20GB.
At the same time, we have also noticed that the 4G network does not fully match the current consumer demand, because we find that as users consume more, the experience speed is getting worse. Taking a domestic operator as an example, in the TOP30 economically developed key cities, the average user perception rate dropped by 53% from 51Mbps at the beginning of 2017 to 20Mbps, indicating that the improvement of network capabilities lags behind the development of users and services. In the current hot spot of a certain tier city in China, the user’s upstream experience rate is only 400Kbps and the downstream experience rate is only 4Mbps. The user experience in this type of area has already become a bottleneck. Poor user experience in hot spots in developed regions is a common problem.
The number of new wireless fixed broadband users exceeds FTTx, becoming the main access method for home broadband services in some areas. Japan's Softbank has launched the Air wireless home broadband service on December 12, 2014. Its experience rate is analogous to optical fiber, without engineering construction, and unlimited traffic. After the launch, it has developed rapidly and added 2 million Air users within 2 years. Air has also attracted a group of specific users, those young people in the city who have no fixed homes, Air users are easy to migrate, and the agreement is flexible. It can be completed within an hour from signing to experience, and can be used immediately after moving. At present, the development of Air business is very hot. Softbank's total traffic increased by 70% in 2016, of which 40% of the growth was mainly contributed by Air users.
On the whole, the rapid growth of traffic, the continuous decline of experience, and the lack of spectrum resources make the deployment of 5G necessary in these places.
To develop 5G, reduce OPEX as a strategic focus
In the past 10 years, mobile operators have supported a 2,000-fold increase in total data traffic with a basically unchanged total CAPEX (the CAPEX revenue ratio has dropped from 17% to 12%). As technology becomes more and more complex, it is difficult for the proportion of CAPEX to fall further.
However, in the past 10 years, the proportion of OPEX has risen from 62% to 75%, and it continues to rise; therefore, in the 5G era, whether the continuous growth of OPEX can be effectively curbed has become the key to commercial success, and it is necessary to reduce OPEX as a strategic focus.
Huawei is willing to work with the industry to realize the historical mission of 5G
With the launch of the 3GPP R15 5G independent networking standard, 5G spectrum in some countries has been released one after another, and 5G will enter the stage of large-scale deployment.
In order to support the construction of 5G networks by global operators, Huawei will launch a complete set of 5G commercial network solutions based on non-independent networking (NSA) on September 30, 2018; on March 30, 2019, it will launch independent networking (SA) ) 5G commercial system. Huawei will also launch a 5G-enabled Kirin chip in 2019, and launch a 5G-enabled smartphone in June 2019, so that consumers who need faster speeds can enjoy the ultimate experience provided by the 5G network as soon as possible. Huawei is willing to work together with the industry to actively invest and continue to innovate to ensure the ultimate realization of the historical mission of 5G.
