LG Uplus and Huawei boost uplink speeds using 2 CC carrier aggregation

South Korean mobile carrier LG Uplus and Huawei claimed today (29 April 2016) that they have improved the uplink data rate to 108 Mbps after deploying uplink 2 carrier aggregation technology (UL 2CC CA) on a commercial network.

LG Uplus is working with Huawei on the world's first commercial deployment of LTE-Advanced Pro based on the latter’s LTE-Advanced Pro version eRAN11.1 solution. With the large-scale release of commercial devices supporting UL 2CC CA, LG Uplus is the world's first cellular carrier to deploy this technology for commercial use.

By aggregating an uplink carrier with a 20 MHz bandwidth in the 2.6GHz band and another uplink carrier with a 10 MHz bandwidth in the 850MHz band, LG Uplus and Huawei were able to achieve uplink data rate of up to 108 Mbps on live networks.

Huawei describes UL 2CC CA as a key aspect of its LTE-Advanced Pro version eRAN11.1 technology, which will enable users to upload files much faster on their mobile devices. LG Uplus launched UL 2CC CA technology in step with smartphones supporting uplink carrier aggregation (UL CA) following a series of successful tests on live networks.

Until recently, most developments have tended to concentrate on improving downlink speeds, but with HD video and photo now standard issue in most devices currently being sold on the market, the need to improve uplink speeds and throughput has become more important.

Additionally, smartphone users expect to be able to share their videos and photos across all mainstream social media platforms. This makes it imperative that uplink rates keep up with developments in smart device technology and changing user expectations.

The world's major cellular carriers see uplink data rate as a major bottleneck in improving user experience. In response, they are looking to new and innovative techniques for improving mobile network uplink data rate to meet ever-growing data usage demands, improve user satisfaction, and increase revenues.

UL CA aggregates multiple LTE carriers to provide larger bandwidths for improved uplink data transmission rates. This technology will meet the growing demand of HD video and photos sharing anytime, anywhere.

According to Huawie, innovations under eRAN11.1 will do much more than improve the uplink user experience for LG Uplus customers. After commercial deployment of downlink 3 carrier aggregation (DL 3CC CA), LG Uplus is exploring new business opportunities under LTE-Advanced Pro, and is currently conducting joint testing of 256QAM to improve downlink data rate.
