leading developer and innovator of advanced wireless technologies, products and

services, and ZTE Corporation, a leading global provider of telecommunications

equipment and network solutions, today announced their collaboration to significantly

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 that is

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.

high-quality and high-capacity network performance,” said Zhang Jianguo, general

manager of ZTE’s UMTS products. “Our ongoing relationship with Qualcomm has

enabled us to commercialize leading edge technologies that bring value to the entire

wireless ecosystem. Using ULIC technology, we are providing operators with a highly

efficient means to optimize their system performance while also extending the lives of

their existing networks.”

“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 vice president, 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. We are pleased to work with ZTE in their

efforts to bring ULIC-enhanced base stations to market.”
