Huawei & Intel Partner for 3GPP “New Radio” Interoperability Testing
On Friday September 22nd, Huawei announced it will collaborate with Intel on the 3GPP “5G” New Radio (NR) based Interoperability Development Testing (IODT). The partnership will pave the way for pre-standard “5G” trials based on 3GPP release 15. Note yet again, that 3GPP release 15 is targeted at “5G” trials, while release 16 will be a submission to the ITU-R IMT 2020 (real) 5G standards.
“The companies will conduct testing in real mobile, over-the-air environments directly connecting Huawei’s infrastructure and Intel’s terminal platform,” Huawei said on Friday.
The company added: “As one of the first globally converged 5G spectrum, C-Band will provide basic coverage and bandwidth for 5G. Further, C-Band will serve as one of the world’s first commercialised 5G frequency bands. The verification of these features that Huawei and Intel have launched will point out the future direction for the industry.”
Based on Huawei’s 5G base station prototype and Intel’s 3rd Generation 5G Mobile Trial Platform (MTP), the companies will jointly verify the performance of key “5G” NR technologies which include: Sub-6GHz including C-Band, mmWave and mobility. The companies will conduct testing in mobile, over the air environments directly connecting Huawei’s infrastructure and Intel’s mobile terminal platform.
“Huawei is committed to driving the development and commercial deployment of 5G technologies. In the IMT-2020 field tests in Beijing, Huawei has fully demonstrated its competency and leadership in C-Band, mmWave, and downlink and uplink decoupling 5G technology. We are excited to work with Intel to help the industry drive the development of 5G terminals to promote sustainable development and ecosystem maturity of the industry chain,” said Yang Chaobin, President of 5G Product Line at Huawei.
“Intel has been actively collaborating with leading players in the Chinese 5G industry to accelerate 5G R&D tests and commercialization with Intel’s end-to-end 5G technology advantages. Based on the latest 5G NR technologies, this joint interoperability test with Huawei will further drive unified 5G standards and the industrial ecosystem in China and across the globe,” said Asha Keddy, vice president in the Communication and Devices Group at Intel Corporation.
Here’s the timeline for 3GPP release 15:
Ongoing 5G Collaboration & Trials:
At the global 5G testing summit at 2017 MWC this past February, Huawei, Intel, and their telecom operator partners jointly announced they would work to drive globally unified 5G standards through 5G testing, enhance cooperation among telecom operators, equipment manufacturers and vertical industry partners, create a unified 5G industry chain from chips, terminals, to network infrastructure and test equipment, and build a global 5G ecosystem. Commencement of IODT seems to be a viable way for Intel and Huawei to achieve this goal.
In January, Huawei demonstrated “5G” like speeds of ~ 35Gbps with Singapore telcos StarHub and M1. The company is working with wireless carriers all over the world (x-US) in “5G” trials.
Intel is working with U.S. carriers AT&T and Verizon on 5G trials. AT&T is using Intel’s 5G mobile trial platform in its Indiana, Texas, and Michigan trials, while Verizon relies on Intel for its 11 pre-commercial 5G trial networks across the nation. Intel is also planning to use the Olympic Games to showcase its 5G “platform.”
Intel and Verizon additionally trialed 5G during the Indianapolis 500 motor race in May, using technologies such as beam forming and beam tracking to attain speeds in excess of 6 Gbps.
–>Having missed out on 4G-LTE by backing WiMAX instead, Intel apparently is trying to catch up by putting a lot of engineering resources into 5G development and collaboration.
“5G standards are moving quickly to unify, and China will be among the first countries to widely deploy 5G networks. Huawei and Intel will work closely to accelerate the era of 5G.”

3GPP New Radio (5G NR), release 15 reallocates some existing LTE bands and introduces new mmWave bands up to 40 GHz. While initial 5G devices will implement some type of point-to-point wireless link, smartphone manufacturers are already planning the introduction of their products that contain multiple radios. Adding yet another radio adds new coexistence challenges that designers must address.
5G NR mid-band (1 GHz to 6 GHz) and high-band (above 24 GHz) operate in the same or in adjacent spectrum to other wireless communications systems. With devices covering multiple bands, there is increased risk for sideband interference or new shared spectrum issues. 5G NR devices will need to operate adjacent to or even in the same spectrum as existing wireless communications systems without causing interference. Designers of 5G chipsets and components need to know the different types of coexistence interference issues, where coexistence interference is likely to occur, and how to test for coexistence interference.
There are many types of coexistence interference, but two primary issues require new coexistence testing. The first involves testing in-band and out-of-band emissions and testing the impact of the 5G NR emissions on other radio signals. These tests are important because you must ensure that a 5G radio doesn’t cause interference with other radios in the device, with other radios signals in the channel, or with signals in an adjacent spectrum. Such testing is similar to 4G coexistence issues, but the increasing number of radios in a device and the increasing number operating bands where 5G NR will operate will compound the problem.
Second, because a goal of 5G is to improve data throughput, shared spectrum will be a key feature in 5G. To operate simultaneously in a shared environment, new procedures and protocols must be developed to ensure successful operation in the environment. At the highest level, these policies specify that devices must listen before they talk. Specifically, a device needs to detect coexistence traffic and allocate or reallocate spectrum dynamically based on what it hears. This presents potential quality of service issues (QoS) issues for device users caused by latencies while the radio switches channels. This will require special tests not previously done on cellular devices.
