China Mobile, Huawei, and Qualcomm Complete LTE TDD Inter-band 3CC CA Commercial Verification
China Mobile recently completed the commercial verification of LTE TDD inter-band 3CC Carrier Aggregation (CA) using Huawei's commercial base station and Qualcomm Technologies’ commercial terminal based on the Qualcomm® Snapdragon 810 processor with X10 LTE. This CA verification combining one 20MHz carrier at 1.9GHz and two 20MHz carriers at 2.6GHz, achieved downlink peak rates of up to 320Mbps.
China Mobile has 1.9GHz and 2.6GHz spectrum available for LTE-A TDD outdoor coverage. To deploy inter-band CA, China Mobile can take full advantage of both 1.9GHz and 2.6GHz spectrums in order to enhance the user’s experience and maintain a competitive edge. Most of China Mobile’s 4G macro deployment is based on 1.9GHz.
China Mobile is upgrading its current network to LTE-A by using CA. In Shenzhen, China Mobile initiated their 2CC CA scale deployment at the end of 2014.
According to the latest GSA report, as of April 2015, 64 operators worldwide in 69 countries have deployed CA, and 116 operators conducted technical test, as well as is focusing on investment. Chipsets and terminals supporting CA are quickly reaching maturity. In addition to playing a significant role in this commercial verification, the Snapdragon 810 process with X10 LTE will also be widely used in upcoming 4G terminals, such as the LeTV smartphone in China, which supports LTE TDD 3CC inter-band CA.
Additionally, most of the latest smartphones, such as Huawei’s Mate7, Honor 6, and Honor 6 Plus and many other brands’ smartphones can support 2CC DL CA.
