Qualcomm demonstrated several advanced 5G technologies for the next phase of the global 5G new air interface (5G NR) standard, which is currently being developed by 3GPP. The first 5G new air interface standard has been completed in the near future to accelerate the deployment of enhanced mobile broadband in 2019. Since then, 3GPP has approved several technical research projects, which are expected to be defined in Release 16 and future releases. The next phase of the development of 5G new air interface.
Qualcomm demonstrated the above technologies in San Diego on February 7 this year. According to the information learned by IT House, from February 26 to March 2 this year, Qualcomm also plans to 3E10 in Hall 3 of the Mobile World Congress in Barcelona. The booth will showcase the above 5G new air interface demonstration and other more demonstrations.
One of the above demonstrations is a live demonstration of the 5G new air interface spectrum sharing technology OTA. 5G spectrum sharing technology is expected to enhance mobile broadband performance in license-free and shared spectrum, and is expected to play an important role in extending 5G to new deployments such as private networks for industrial IoT. This demonstration demonstrates advanced spatial domain spectrum sharing techniques that rely on the concepts of spatial domain multiplexing (SDM) and coordinated multipoint (CoMP). This technology increases network capacity and user throughput by enabling tighter user coordination on license-free and shared bands.
The demonstration uses Qualcomm's previously announced 5G new air interface spectrum sharing prototype system, which also supports 5G new air interface testing in license-free spectrum, including license-assisted access (LAA) and independent operation without license anchor, ie 5G MulteFire .
In addition, Qualcomm also demonstrated the industry's first 5G new air interface wireless PROFINET Industrial Ethernet demo. The private 5G network for the Industrial Internet of Things is the focus of the next phase of the 3GPP 5G new air interface. The ability to run Industrial Ethernet over a wireless network drives factory reconfiguration to increase productivity and flexibility, which is a key concept in Industry 4.0. The demonstration previews a new use case for 5G new air interface URLLC (Ultra-Reliable Low Latency Communication) that supports sub-millisecond latency, including the ability to accurately command and control in demanding factory automation applications.
In addition, Qualcomm also demonstrated the importance of C-V2X technology based on 5G new air interface in achieving autonomous driving. This technology can help cars communicate their intentions and thus support the high predictive power required for advanced path planning. C-V2X technology based on 5G new air interface enhances existing C-V2X technology through complementary functions, supporting simultaneous backward compatibility of high throughput and URLLC functions to support advanced autonomous vehicle use cases, including high throughput sensors, Intent sharing and 3D HD map updates.
