5G-A milestone! China Academy of Information and Communications Technology takes the lead in completing the evolution of 3GPP R18 terminal air interface performance standards

According to news on June 26, at the recent 104th meeting of 3GPP RAN (Radio Access Network Project), the 3GPP Release 18 (R18) standard was officially frozen.

The R18 standard took more than 3 years from project establishment to freezing. It is the first version of 5G-Advanced (5G-A/5.5G).

Compared with traditional 5G, the network capabilities of **ultra-high-speed** 5G-A can be improved **ten times**, and can support **10G** experience and **100 billion-level** connections , the downstream peak value is upgraded from **1 Gigabit** to **10 Gigabit**, and the upstream peak value is increased from **0.1 Gigabit** to **1 Gigabit**.

, According to the official account of Taier Terminal Laboratory, the "NR User Equipment Multiple Input Multiple Output (MIMO) ** Air Interface (OTA) ** Test Method and Performance" led by China Academy of Information and Communications Technology **Tier Terminal Laboratory** The "Requirements Enhancement" R18 standard project was approved and completed, successfully completing the R18 version evolution of the international standard 3GPP TS38.151, and outputting the technical report 3GPP TR38.761.

This marks the release of the “full version” of 5G Sub-6GHz and millimeter wave band MIMO OTA performance requirements standards, and the industry has made new breakthroughs in the field of 5G terminal test standardization.

It is reported that mobile terminal **wireless** air interface testing is currently the mainstream testing method for measuring and evaluating the transmitting and receiving performance of the entire machine through the air interface. Its **key** performance indicators directly affect the stable connection of the network. Data transfer rate and user experience.

MIMO OTA test simulates real multipath fading channel conditions in the experimental environment and is an effective method to measure and verify the actual communication performance of the terminal.

This R18 standard project further improves and enhances the 5G terminal MIMO OTA test methods and performance requirements, covering the 5G FR1 and FR2 frequency bands, and will effectively guide the industry to carry out terminal MIMO OTA performance measurement through repeatable and debuggable standardized methods. and verification to ensure the communication quality and user experience of 5G and 5G-A terminals in real network environments, and support the high-quality development of the mobile communications industry.
