Qualcomm implements multiple functions of C-V2X technology for 5G evolution. 1 Multiple C-V2X direct-link technology use cases
In the real-world use case test of the car network, the use case for C-V2X technology is the “see-through†use case between two connected cars on the road, and the real-time notification of the emergency vehicle approaching when the emergency vehicle approaches. "Example.
The above two use cases are currently being developed and tested in the trial network, using lower latency and high throughput performance to achieve high-resolution video streaming between the two cars through the C-V2X network function, demonstrating its responsiveness. And real-time event notifications.
Qualcomm works with PSA Peugeot Citroen, Orange and Ericsson to deliver C-V2X technology in R14 and its powerful evolution towards 5G through network-based communications and direct communications, enabling greater security, greater connectivity and more The shared vision of intelligent transportation.
The C-V2X technology defined in the 3GPP Release 14 specification is expected to support security and other enhanced use cases. Subsequent versions of the 3GPP specification, including the 5G new air interface, are expected to evolve network and direct communication to support front-end use cases and enable autonomous driving.
2 Qualcomm's next-generation wireless technology automotive 5G and C-V2X solutionsIt is understood that Qualcomm and LG have passed a number of technical tests and will launch a new generation of wireless technology in the first half of 2018.
LG develops advanced vehicle networking solutions based on Qualcomm Technologies' connected car platform that supports Gigabit LTE speeds with Qualcomm® X16 LTE modems and complements the QCA65x4 Wi-Fi 802.11ac solution. The platform also supports 802.11p/DSRC and C-V2X technology based on the 3GPP Release 14 specification.
The advanced wireless capabilities of 5G and C-V2X technologies will support a variety of new use cases that are necessary to achieve a more connected and more automated automotive vision.
C-V2X technology is a key feature of automotive safety solutions and autonomous driving solutions with a strong 5G evolution path. The C-V2X complements other advanced driver assistance systems (ADAS) sensors such as cameras, radars and lidars to provide information in the surrounding environment, even in non-line of sight (NLOS) scenarios. In addition to supporting 360-degree non-line-of-sight, the C-V2X also supports enhanced context awareness, which detects and utilizes direct communication over the 5.9 GHz ITS band to exchange information with other vehicles, infrastructure, and pedestrian terminals, as well as commercial The cellular technology band communicates with the cloud service. Compared to current technologies, the C-V2X extends the distance of V2X direct communication, improves reliability, reduces latency, and provides superior non-line-of-sight performance. Based on the 3GPP Release 14 specification, this technology has been widely supported by the ecosystem and is expected to be tested this year.
Wireless communication provides data to the vehicle that is truly complementary to the information provided by other sensors. Taking the C-V2X as an example, the technology and its evolution towards 5G can help the car identify the surrounding environment. A pedestrian or a car can be detected by a pedestrian's smartphone, even if they are being built by the building. Or other large cars are blocked.
In the process of C-V2X evolution to 5G, it can provide more wireless communication functions for autonomous vehicles to support a variety of leading edge use cases, such as high-throughput sensor data and map sharing between vehicles, capturing information from vehicle cameras. Streaming to other vehicles for "see-through" functionality, or enabling broadband ranging to improve location services; at the same time, it will also be backward compatible with 3GPP Rel. 14 C-V2X technology. The 5G is capable of supporting ultra-high-speed and massive nodes of several gigabits per second, and supports mission-critical services through ultra-reliable, low-latency communications, which will provide a unified connectivity platform for autonomous vehicles that are always connected in the future.

Qualcomm Gigabit LTE commercial chip for LAA supportAt the MWC booth, Qualcomm demonstrated Gigabit LTE using Granted Assisted Access (LAA) technology. The data transmission rate is greatly improved by using the unlicensed spectrum and the licensed spectrum simultaneously by the LAA.
The demonstration achieves a 1Gbps rate by aggregating bands up to 80 MHz on licensed and unlicensed bands and using a mobile test terminal integrated with X16 LTE's Qualcomm® SnapdragonTM 835 processor. With the support of the "Listen Before Talk (LBT)" mechanism defined by the European Telecommunications Standards Institute (ETSI), fair system coexistence can be achieved by different system operations on the same unlicensed band.
The company achieves theoretical peak rates of up to 1 Gbps through the deployment of small base stations and the use of technologies such as carrier aggregation and LTE Authorized Access (LAA).
The LAA feature provides the reliability and seamless mobility of LTE-licensed spectrum and enables a significant increase in throughput through the use of unlicensed spectrum. For some deployment scenarios (eg, next-generation small base stations in high-use areas), it will be a promising solution.
By leveraging the LAA, users will be able to enjoy a better LTE experience as unlicensed spectrum can be used to increase data rates. LTE and Wi-Fi users will coexist fairly in unlicensed bands, and end users will benefit both indoors and outdoors.
