Qualcomm completes 5G-A high and low frequency NR-CA end-to-end verification: achieving a new breakthrough in 9Gbps ​​rate

News on July 22: Recently, China Mobile Research Institute, ZTE and Qualcomm Technologies collaborated to verify the 5G Advanced high and low frequency multi-carrier aggregation solution, successfully demonstrating the high-speed experience under the new NR-CA combination. This verification uses the 800MHz bandwidth of the ultra-high frequency band and the 100MHz bandwidth of the 2.6GHz low-frequency band for carrier aggregation, and uses the 1024QAM high-order modulation method for the first time to achieve a new breakthrough of a single user downlink peak rate of 9Gbps. The three parties jointly achieved end-to-end NR-CA technology verification, using smartphone-shaped terminals equipped with Snapdragon X80 5G modem and radio frequency system, and ZTE's high-performance ultra-wide bandwidth millimeter wave AAU equipment.

It is understood that the Snapdragon X80 5G modem is the seventh-generation 5G modem launched by Qualcomm in February this year, integrating a dedicated 5G AI processor and 5G Advanced-ready architecture.

It achieves several firsts:

1. First time integrating NB-NTN satellite communications in a 5G modem
2. First time supporting 6Rx for smartphones
3. First downlink six carrier aggregation
4. First time for fixed wireless access client devices (CPE) supports millimeter wave extended range communication empowered by AI
