First, the first 5G new air interface (5G NR) specification to be implemented at the 3GPP TSG RAN plenary in Lisbon, Portugal, was recently completed. For a time, there were three major operators in China, the four major carriers in the United States, Qualcomm and ZTE All 30 leading mobile operators made a statement saying that this is a "milestone" event.
On the same day, Ericsson and Qualcomm unveiled multi-vendor interworking connectivity demonstrating compliance with the global 3GPP non-independent 5G new air interface standard with AT & T, NTT DOCOMO, Orange, SK Telecom, Sprint, Telstra, T-Mobile USA, Verizon and Vodafone End-to-end 5G air interface systems below 6GHz and millimeter-wave bands operate in the 3.5GHz and 28GHz bands respectively for low-level data connections.

Crude above two things, are to speed up the 5G commercial, but behind it all have more profound significance.
The first 5G new air interface standard introduced is not easy, which involves the interests of enterprises between the game - once in the 2015 3GPP conference, more than 500 companies joined the 5G standard discussion, provided more than 70 kinds of programs, in two parties Many work together to finally reach a consensus.Although the introduction of 3GPP is only a 5G preliminary standard, complete specifications from the 5G standard for some time, but this is still a landmark, intended to complete a non-independent 5G NR configuration related technology Specification, support 5G mobile phone and 5G network arrived early in 2019 as soon as possible, 5G profile more and more clear.
The multi-vendor interworking demonstration mentioned above is an important technological achievement of continuous industry cooperation and a milestone in promoting standard 5G pilot and commercial development to accelerate the deployment of 5G new air interface commercial network started in 2019.
In this one, Qualcomm has always played an important role as an innovator in the field of mobile communications.
5G R & D is not overnight, huge investment and rich reserves of intellectual property are essential.As Qualcomm Engineering Senior Vice President Durga Malladi interpretation: '5G business path is not a short sprint, but in the 3GPP 5G standardization work This path to 5G commercialization is not a short sprint, but rather a marathon that started long before the 3GPP 5G standardization efforts kicked off. "
We know that the iterative evolution of communications technology requires more than just a global standard such as the 3GPP to provide forward-looking technology solutions from technology companies like Qualcomm, which can truly push the industry forward. "Qualcomm began as early as a dozen years ago Began to invest in 5G prospective research and has been contributing 5G design to 3GPP, including OFDM-based waveforms, advanced channel coding, millimeter-wave and so on, plus the evolution of 4G LTE and gigabit LTE for 5G development Pave the way.
On October 18, 2016, Qualcomm introduced the world's first 5G modem based on the 28-millimeter-wave band, the Xiaolong X50, which supports the current global 2G / 3G / 4G and 5G multimode networks through a single chip and supports the global 5G new air interface Standard and gigabit LTE network mean that operators and OEMs can deploy next-generation cellular network terminals ahead of schedule In February 2017, the Snapdragon X50 was further expanded to support operation in the band below 6GHz, which will result in a downstream rate of 5Gbps .
In September 2017, Qualcomm introduced a 5G new air interface millimeter wave prototype system based on the 5G NR Release-15 specification to accelerate mobile deployment for smartphones, which operates in the millimeter-wave band above 24GHz and which is also Demonstrating QUALCOMM's millimeter-wave radio-frequency front-end design optimized for smart-phone-sized terminals to test and test millimeter-wave challenges in real-world environments such as signal blockage caused by terminal design and hand grips, and shortly thereafter, Qualcomm has introduced a tiny millimeter-wave antenna module, the size of a nickel equivalent, much smaller than competing products.
In October, Qualcomm launched its first 5G smart phone reference design based on the Snapdragon X50 5G modem chipset in the world's first 5G data link in the 28GHz millimeter-wave band. The first 5G smart phone reference design, a body thickness of less than 9mm, with a narrow bezel design Based on this solution, OEMs have already been able to achieve trial production and testing of 5G handsets ahead of schedule. Qualcomm expects smartphones equipped with Snapdragon X50 5G modems to be available in the first half of 2019.
In addition to its own technical achievements, Qualcomm has been working with industry chain partners to promote the pre-commercial 5G testing and testing.
Domestically, Qualcomm conducted tests with ZTE and China Mobile in February 2017. Since then, the three giants announced in November that the lab of China Mobile 5G Co-Innovation Center has successfully implemented the world's first 3GPP R15-based end-to-end End 5G NR system interoperability (IoDT). The system operates in the 3.5GHz frequency band, supports 100MHz high bandwidth, and the protocol implements a new air interface Layer 1 architecture fully compliant with the 3GPP R15 standard.The result is an important milestone in the pre-commercial 5G process, The 5G use cases that require low latency and high reliability are essential for achieving widespread coverage and capacity in China for future 5G use cases. At the end of 2017, the Ministry of Industry and Information officially released the frequency plan for the 5G system in the mid-band of China, where Including the 3.5GHz band.It is not difficult to see that the achievement of this achievement for the development of the domestic 5G industry chain has an important role.
Qualcomm and ZTE to Achieve Interoperability for 5G NR Systems Operating at 3.5GHz (IoDT)
Globally, Qualcomm has also been working with partners on 5G-related trial cooperation.Recent example is December 15 last year, Qualcomm, ZTE, Wind Tre announced the 3.7GHz band launch 5G trial cooperation, the test will verify the 5G service And technology to enable a standard 5G new air interface infrastructure and terminal ready to accelerate the timely deployment of 5G commercial networks The trial will be launched in the 3.7GHz band and will demonstrate a number of advanced 5G technologies to achieve per second Gigabit speeds, lower latency, and higher reliability, these 5G technologies will be essential technologies to meet the ever-increasing demand for mobile broadband experiences for subscribers and provide the smart city, car networking, e-health, smart energy And Industry 4.0 and other areas of service needs laid the foundation.
