Behind the world's first end-to-end 5G new air interface system interoperability: Qualcomm boosts 5G to accelerate commercial use.

Release time:

2020-09-05

The 5G standard process is in full swing, and the time for commercial use in 2020 is close at hand. According to the 5G acceleration proposal officially adopted by 3GPP, 3GPP will freeze the 5G new air interface (NR) non-independent networking standard in R15 version next month. As an important part of 5G, 5G new air interface technology has also received extensive attention recently.

Recently, Qualcomm, ZTE and China Mobile officially announced the successful realization of the world's first end-to-end 5G new air interface system interworking based on the 3GPP R15 standard. The interoperability demonstration was conducted in the laboratory of China Mobile's 5G Joint Innovation Center and was completed using ZTE's 5G new air port pre-commercial base station and Qualcomm's 5G new air port terminal prototype. In the last two days, the China Mobile Global Partner Conference is being held in Guangzhou. As an important achievement of the continuous cooperation among the three parties, the end-to-end 5G new air interface system interoperability was also demonstrated on the spot for the first time.

This achievement has promoted the rapid development of 5G networks and terminal industries in line with 3GPP standards.

Not only that, Qualcomm has also deployed 5G modem chipsets, 5G data connections, and 5G smartphone reference designs. These results have allowed people to see that the door to 5G is opening from both the network side and the terminal side. In addition, Qualcomm has done a lot of work in promoting global standard development, trials and tests, and productization, and continues to accelerate global 5G deployment.

The three parties have joined forces to successfully achieve the world's first 5G new air interface system interoperability.

On November 17, Qualcomm, ZTE and China Mobile officially announced the successful realization of the world's first end-to-end 5G new air interface system interoperability (IoDT) based on 3GPP R15 standard.

The end-to-end 5G new air interface system operates in the 3.5GHz frequency band and supports a large bandwidth of 100MHz. The protocol implements the new air interface Layer 1 architecture defined by 3GPP R15 standard, including scalable OFDM parameter configuration, advanced new channel coding and modulation scheme, and low-delay self-contained frame structure. It can efficiently realize a single user transmission rate of several G bits per second, and significantly reduce the air interface delay compared with 4G.

Qualcomm Executive Vice President and President of QCT Cristiano Amon said, "Achieving the world's first 5G new air-to-air end-to-end system interoperable data connection truly demonstrates our 5G leadership and helps ensure the timely deployment of standards-compliant 5G commercial networks. Qualcomm has been committed to supporting the long-term success of China's wireless industry, and we are pleased to work with ZTE and China Mobile to accelerate the 5G process in China."

At present, the International Organization for Standardization 3GPP is developing a new 5G air interface standard. The new 5G air interface will make full use of a wide range of spectrum resources, and the use of sub -6GHz bands will be critical to achieve comprehensive coverage and the capacity to meet a large number of future 5G use cases.

Leading in an all-round way to promote the 5G commercial road

Qualcomm has made many predictable deployments in the 5G field and is promoting the global 5G commercial road in all directions.

For example, on October 17 this year, Qualcomm announced the success of 5G data connection based on the Xiaolong X50 5G modem chipset, which is a chipset for mobile terminals and realizes gigabit rate and data connection on the 28GHz millimeter wave band.

It is reported that the modem chipset can support operation under 6GHz and multi-band millimeter wave spectrum, and can support 2G/3G/4G/5G multimode functions through a single chip. The ability to move from product release to functional chip capability in 12 months is a clear indication that Qualcomm's lead in cellular technology extends to 5G.

At the same time, Qualcomm demonstrated its first 5G smartphone reference design, which aims to test and optimize 5G technology under the power and size requirements of the phone. This 5G smartphone reference design provides a good reference standard for the entire mobile phone terminal manufacturer. Future 5G mobile phones can conduct in-depth testing and optimization of 5G technology under the design size and power consumption standards of this prototype. Terminal manufacturers can use this as a reference to launch better 5G terminal products for consumers.

Up to now, Qualcomm has launched a "full coverage" 5G new air interface prototype system for below 6GHz, millimeter wave band and spectrum sharing technology to support testing, demonstration and verification of 5G design, promote and track the standardization process of 3GPP 5G new air interface, and accelerate large-scale testing and commercial deployment of 5G new air interface.

Of course, Qualcomm is also developing a number of key 5G technologies at the same time. Gigabit LTE, channel coding, independent subframes, millimeter wave mobility, massive MIMO and other 5G technologies have their corresponding research and deployment.

In addition, the development of 5G is inseparable from the cooperation of the industry. Since this year, Qualcomm has joined hands with China Mobile, AT&T, Vodafone, NTTDOCOMO, Telstra, SK Telecom and other leading operators to carry out a series of interoperability tests and OTA field tests based on 5G New Air Port (5G NR) specifications worldwide. Qualcomm also maintains close cooperation with partners and customers in all aspects of the Chinese industrial chain, and will make every effort to accelerate the global-especially the Chinese market -5G commercial deployment.

Experiment with 5G next year! China Mobile's 4G user tariffs continue to fall

Qualcomm 5G patent licensing fee is expected to be large-scale commercial in 2019.
