SHENZHEN, China -- Huawei recently launched the uX2 solution to help operators provide improved cell edge user experience and release network potential. The innovative uX2 solution has already found success in large-scale commercial use in Thailand and through pilot stage deployment in live networks in Hong Kong, Lithuania, and the United Arab Emirates.
With the fast development of mobile broadband, users have higher demands for better experience, driving operators to improve cell edge user experience. The X2 interface in the LTE networks plays a crucial role in solving these issues. Based on the concept of ‘Utilizing 4G Technologies in 3G’, Huawei introduces the uX2 interface in the ‘UMTS+’ solution to allow for fast information exchange among NodeBs and reshape the radio access architecture.
This eliminates the need for the Radio Network Controller (RNC) to forward information. Based on the uX2 interface, Huawei has launched a series of innovative solutions to achieve coordinated scheduling for the high-speed services among NodeBs, improving the peak rate for cell edge users and helping more users to enjoy high definition videos and other mobile data services in the UMTS networks anytime, anywhere.
The uX2 solution improves cell edge user experience and provides larger capacity in cell edge areas, further enhancing the cell edge throughput. Commercial data for networks in Thailand demonstrates a 15% increase in uplink cell edge throughput, which will be reinforced with future growth in cell traffic. In addition, pilot deployment returns numerous benefits. For example, the cell edge uplink rate increased by 70% in drive tests in Lithuania and the downlink cell edge throughput improved by more than 50% in drive tests in Hong Kong.
