Qualcomm, ZTE collaborate on UMTS

Qualcomm Inc. and ZTE Corp. will collaborate to enhance the capacity and performance of UMTS systems with the integration of Qualcomm's Uplink Interference Cancellation (ULIC) technology into ZTE's next-generation UMTS base station products.

Using this technology, operators can boost their UMTS data throughput by up to 60 percent and deliver a user experience comparable to LTE in a similar channel bandwidth. The technology also enables UMTS operators to increase voice capacity by up to 45 percent.

ULIC technology can deliver improved system capacity by eliminating interference from multiple uplink data streams. Enabled by the increased level of integration possible in today's commercial chips, ULIC brings the performance of CDMA-based modems close to their theoretical limits. The design is scalable and supports cancellation for a large number of simultaneous users and transmissions on the uplink.

"ZTE serves the world's top mobile operators based on our ability to consistently deliver high-quality and high-capacity network performance," said Zhang Jianguo, general manager of ZTE's UMTS products.

"Interference cancellation is helping to redefine the performance characteristics of UMTS by improving system capacity and delivering data throughput that is on par with LTE networks," said Jing Wang, executive VP of Qualcomm Asia Pacific, Middle East and Africa. "It not only provides faster speeds, but also creates a better experience for the growing number of people using mobile devices to upload and share data-intensive content, such as photographs and videos."
