it house reported on october 6 that during the "collaborative mass creation, smart future, and set sail for the future - 6g innovation and development forum" hosted by china mobile at the end of september, china mobile, zhongguancun joint research institute, citic mobile and vivo and others showed6g baseband concept prototype system for sub7ghz frequency band。

as an important component of the "6g synesthesia computing intelligence fusion technology platform", this system has a flexible and open system architecture. it was selected into the top ten digital technology achievements of state-owned enterprises in 2024 and the major scientific and technological achievements of the zhongguancun forum in 2024.

china mobile said that the 6g baseband concept prototype system for the sub7ghz frequency band is an important core of china mobile's public test device base for synesthesia computing and deep integration of space and earth. the system has the following characteristics:

first, strong basic ability. the system is based on cloud-based heterogeneous hardware, supports 100gbps container network throughput, achieves ultra-short tti processing capability of 125us, has a maximum interrupt response delay of less than 10μs, and is flexible and reconfigurable. it has system capabilities of 8 streams, 128 digital channels, and a single carrier bandwidth of 400mhz. it can achieve a baseband real-time throughput of up to 16.5gbps, fully meeting the high requirements of 6g new technologies and service verification.

second, strong openness. the system realizes the connection between the cloud heterogeneous hardware base developed by china mobile and the zhongguancun joint research institute, the sub7ghz aau developed by citic and the terminal prototype developed by vivo, and realizes the connection from the base station to the terminal business plane, supporting 3d video service transmission. . the system has open sharing capabilities and supports joint 6g key technology verification with industry partners.

third, strong scalability. in response to the key technology verification needs of 6g new frequency bands, china mobile and zhongguancun pan-joint research institute independently designed a multi-band integrated universal fronthaul module, which is connected to the bbu of the 6g baseband concept prototype system through an ultra-high-speed cpri interface, achieving a wide range of 0~12ghz flexibility the transmission of variable intermediate frequency signals enables the system to efficiently interface with multi-band rf front-ends such as mid-low frequency, millimeter wave, visible light, and terahertz, achieving multi-band adaptability and more conveniently carrying out key components and baseband processing in new frequency bands. technology testing and verification.

the 6g baseband concept prototype system for sub7ghz is the core content of the 6g synesthesia computing and intelligence integration research and development test device, and will serve the entire innovation process of 6g key technologies, system design, standard formulation, industrial development and network testing.

it house also learned from the forum that china mobile, beijing university of posts and telecommunications, and zhongguancun joint institute jointly demonstrated 6g synesthesia computing intelligence fusion and open network simulation platform。

the 6g synesthesia computing and intelligence fusion and open network simulation platform achieves a flexible expansion architecture with high cohesion and low coupling through the division of protocol levels and modular design.can conduct a comprehensive systematic assessment of key 6g network technologies. the platform supports four major capabilities: multiple scenarios, multiple channels, multi-point verification, and multi-dimensional evaluation.
