Qualcomm and NTT DOCOMO Enable Commercialization of 5G Sub-6 GHz Carrier Aggregation in Japan

NTT DOCOMO

Qualcomm and NTT DOCOMO have together enabled the commercialization of 5G sub-6 GHz carrier aggregation (sub6-CA) in Japan, effective immediately, to bring multi-gigabit mobile experiences to DOCOMO customers. Deployment of 5G carrier aggregation, a critical capability in 5G specifications, is enabling customers to now enjoy improved performance on DOCOMO's rapidly expanding 5G network.

Using DOCOMO's new 5G network and select devices powered by the Qualcomm® SnapdragonTM 865 Mobile Platform with the Snapdragon X55 5G Modem-RF System, customers can now get mobile download speeds of up to 4.2 Gbps. This level of service is achieved through 5G sub-6 GHz carrier aggregation, which combines a 100 MHz carrier in band n78 and a 100 MHz carrier in band n79 to boost 5G performance and network capacity using DOCOMO's diverse spectrum assets.

The deployment of 5G Sub6-CA, along with 5G mmWave 28 GHz band that DOCOMO began operating commercially in September, will unleash the full potential of 5G and enable accelerated deployment of DOCOMO's 5G service areas.
