The three parties will cooperate in stages to carry out positioning technology based on the completed 3GPP 5G NR Rel-16 standard specifications and performance verification based on the future 3GPP Rel-17 enhanced positioning technology specifications.
China Mobile Research Institute, ZTE and Qualcomm Technologies announced today that based on the principle of long-term development and benefiting the industry, the three parties will cooperate in stages to carry out positioning technology based on the completed 3GPP 5G NR Rel-16 standard specification and performance verification based on the future 3GPP Rel-17 enhanced positioning technology specification. This cooperation aims to accelerate the standard development and implementation of 5G positioning technology and enrich the application scenarios of 5G positioning technology in emerging vertical industries. The three parties plan to demonstrate the above 5G positioning technology in 2021 and in the future.
The first phase of 5G deployment based on 3GPP Rel-15 focuses on providing a new and enhanced mobile broadband experience for smartphones and other terminals, while in the next phase (3GPP Rel-16, 17 and future versions), 5G will enable more applications and industries, such as industrial Internet of Things, automobiles, augmented reality, etc. Accurate terminal positioning is an important feature for realizing many applications including augmented reality and indoor navigation. Cellular technology-based positioning can complement the existing global navigation satellite system (GNSS) to meet the needs of outdoor and indoor positioning.
In the 4G era, China Mobile has commercialized indoor positioning solutions based on UTDOA technology. 5G has a larger system bandwidth and supports large-scale MIMO antenna arrays, which can support higher-precision positioning. The 3GPP Rel-16 specification introduces a new RTT (round-trip time)-based positioning technology that does not require strict network synchronization to provide reliable positioning performance. It also introduces new 3D angle of arrival/angle of departure (AoA/AoD) measurements to further improve positioning accuracy. Using the high temporal resolution provided by 5G's large bandwidth and the multi-beam angle information provided by large-scale MIMO, 5G can achieve a single positioning accuracy of less than 10 meters outdoors and less than 3 meters indoors. If additional filtering and fusion positioning technology of multiple sensors are used, the positioning accuracy can be further improved. The 3GPP Rel-17 specification currently under development will continue to evolve on the basis of 3GPP NR Rel-16 positioning technology, with the goal of achieving sub-meter accuracy and meeting the absolute accuracy requirements of less than 0.3 meters for single positioning.
The 3GPP Rel-16 positioning technology performance verification carried out by the three parties mainly includes the verification of positioning accuracy that can be achieved under different positioning technologies (such as RTT and AoA/AoD) and different standardized positioning reference signal configurations, as well as positioning performance evaluation in indoor, outdoor, stationary and mobile scenarios. Future tests based on 3GPP Rel-17 enhanced positioning technology will focus on the evaluation of new 5G application scenarios based on sub-meter positioning accuracy.
Huang Yuhong, Vice President of China Mobile Research Institute, said:
"5G+positioning" is an important part of China Mobile's integrated innovation capability system, which can expand indoor and outdoor vertical industry applications. At present, China Mobile has built a "5G+Beidou" high-precision positioning network covering the whole country, which can provide outdoor centimeter-level positioning capabilities. In order to build an integrated indoor and outdoor positioning network, China Mobile is actively promoting more commercial testing and standard pre-research of 5G positioning technology, and applying it to indoor scenes and outdoor blocked areas.
Bai Yanmin, General Manager of ZTE’s 5G Products, said:
With the large-scale deployment of 5G networks, developing and utilizing the positioning capabilities of 5G networks, providing support for industrial applications, driving the development of positioning services, and empowering thousands of industries are one of ZTE's goals. This tripartite cooperation is a phased achievement in our exploration and promotion of the development of positioning technology. We believe that with the joint efforts of industry partners, we will promote and catalyze the further development of the positioning industry and enable 5G networks to better empower thousands of industries.
Simon Chuang, Vice President of Engineering at Qualcomm Technologies, said:
We are pleased to work with China Mobile Research Institute and ZTE to accelerate the evolution of 5G positioning technology and promote this technology to better meet the needs of more applications and vertical industries. This cooperation with leading companies in the global communications industry is another example of Qualcomm Technologies' continued deepening of ecosystem cooperation to promote the continued expansion and evolution of 5G around the world. We expect that the technical results of this cooperation will support many industries to create new 5G opportunities and bring more possibilities to the future of smart connectivity.
