5G commercial is coming soon. Qualcomm and China Mobile and ZTE jointly develop 5G new air interface system interoperability. The application of 5G new air interface technology is essential to meet the growing demand for data connection and realize full spectrum connection.
Following the launch of the 5G modem chipset X50 and the 5G data connection based on the 28GHz millimeter wave band, Qualcomm once again demonstrated its strength in the 5G pre-commercial phase. On November 17, Qualcomm, ZTE and China Mobile jointly announced the successful implementation of the world's first 3GPP R15-based end-to-end 5G new air interface (5G NR) system interworking (IoDT), which is based on the 3.5GHz band. ZTE's 5G new air pre-commercial base station and Qualcomm 5G new air interface terminal prototype realize end-to-end system interoperability.
"According to the 3GPP new air interface development of 3GPP, it is currently in the R15 project phase." 3GPP is formed by the cooperation of seven global standards development organizations (SSO), which defines a complete end-to-end system specification to ensure that the entire system can complete communication needs. Cover all the elements needed for the overall network, especially for more complex 5G communications.
As an important 3GPP member company, Qualcomm is promoting the evolution of 3GPP 5G new air interface and accelerate the promotion of 5G commercial. It is understood that this is the world's first end-to-end 5G new air interface system based on 3GPP R15 standard. It runs in the 3.5GHz band and supports 100MHz large bandwidth. The protocol realizes the new air interface Layer 1 architecture fully defined by the 3GPP R15 standard. Scalable OFDM parameter configuration including 5G new air interface system requirements, advanced new channel coding and modulation scheme, and low-latency self-contained frame structure, which can efficiently achieve single-user G-bit transmission rate per second, compared with 4G The air gap delay is significantly reduced.
Christopher Amon, Executive Vice President and QCT President of Qualcomm, said: "To achieve the world's first 5G new air interface end-to-end system interoperable data connectivity truly reflects our 5G leadership and helps ensure a standards-compliant 5G commercial network Timely deployment. Qualcomm has been committed to supporting the long-term success of China's wireless industry, and we are also very happy to work with ZTE and China Mobile to accelerate China's 5G process."
At present, Qualcomm has maintained its leading position in the pre-commercial phase of 5G. Not long ago, it released the first prototype of 5G smartphone reference design. The reason why ZTE has jointly implemented 5G new air interface end-to-end system interoperability is because ZTE It is expected to be the first supplier of 5G commercial equipment and solutions.
ZTE CTO and Senior Vice President and Xu Huijun said: "ZTE is committed to becoming the first supplier of 5G commercial equipment and solutions. In the process of 5G technical verification and product development, we have been actively cooperating with industry partners. A large number of key technology verification, solution verification and network verification work. This time ZTE and China Mobile, Qualcomm Technologies jointly completed the world's first 5G new air interface interoperable data connection, reflecting our efforts in promoting 5G industrialization and Phased results."
Undoubtedly, the successful interoperability of the end-to-end 5G new air interface system is an important industry milestone for 5G new air interface technology to large-scale pre-commercialization, and promotes the rapid development of 5G network and terminal industry in line with 3GPP standards.
Achieve full spectrum connectivity with 5G commercial capabilitiesThe application of 5G new air interface technology is critical to meeting the growing demand for data connectivity, and will support emerging mobile broadband experiences such as high-definition video streaming, immersive virtual/augmented reality, and autonomous vehicles, drones, and industrial controls. Provide new services with high reliability and low latency.
Of course, for 5G new air interface applications, 5G data connections need to achieve full spectrum connectivity to implement these new services and applications. Previously, the Qualcomm Xiaolong X50 chipset has taken the lead in achieving 5G data connection in the 28GHz millimeter wave band.
Cristiano Amon told reporters that Qualcomm first implemented 5G data connection at 28GHz, which was driven by the US spectrum license and operator deployment. We conducted a lot of field tests at 28GHz. At the same time, we have announced several trials using the Qualcomm 5G prototype system. There are still many trials still underway this year, both in the 28GHz millimeter wave band and in the 6GHz band. Qualcomm will support the 5G NR smartphone that was first introduced in 2019, which will allow for full-band 5G data connectivity.
Today, Qualcomm is once again the first to implement the 5G new air interface system interoperability based on the 3.5GHz band below 6GHz, and is also driven by China Mobile, the world's largest operator, in line with Qualcomm's 5G progress forecast, which also means that Qualcomm already has the industry. The first to support 5G full spectrum commercial capabilities. Li Zhengmao, vice president of China Mobile Communications Corporation, said: "China Mobile is committed to promoting globally unified 5G standards with industry partners. The completion of the end-to-end intercommunication test based on the 3GPP standard version 5G new air interface is 5G from standard to pre-commercial and pre-commercial. Important milestones. China Mobile is willing to work with Qualcomm and ZTE partners to promote the maturity of 5G products and the success of the industry."
