China Mobile and Huawei jointly completed an uplink Carrier Aggregation (CA) field testing and validation that uses 64QAM (Quadrature Amplitude Modulation) using Jiangsu Mobile’s commercial network. Huawei claims that the testing which is a step closer towards actual commercialization is a first the world and showed a 180% increase in uplink rates. The uplink CA is a key LTE-Advanced technology and can dramatically increase uplink data rate which could greatly enhance the user experience when using upload services. The testing was conducted using pictures and video sharing by individual users, as well as video surveillance, telemedicine, and shoot-and-transmit for enterprise users.
Huawei said that its uplink CA solution can easily be adopted using a simple software upgrade, effectively eliminating the need for operators to purchase additional equipment and it will continue playing an important role in accelerating the commercialization of uplink CA together with all global operators and industrial partners.
Besides this uplink CA verification, China Mobile has already started upgrading the entire network in Shenzhen to TDD LTE-A by enabling the downlink CA.
