Qualcomm and Huawei to Cooperate on Advanced UMTS Node B Receiver Technology

Uplink Interference Cancellation to Significantly Increase Data and Voice Throughput.

SAN DIEGO .— Qualcomm Incorporated (Nasdaq: QCOM), a leading developer and innovator of Code Division Multiple Access (CDMA) and other advanced wireless technologies, and Huawei Technologies (“Huawei”), a leader in providing next generation telecommunications network solutions for operators around the world, today announced the signing of a technology transfer agreement for advanced Node B (base station) receiver design that can benefit all UMTS systems, Release 99 and onwards. For example, the agreement covers new technology that can boost the data throughput performance of High Speed Uplink Packet Access (HSUPA) networks by up to 60 percent. Technology transferred by Qualcomm under this agreement will enable Huawei to deploy highly advanced 3G networks in markets using any UMTS-based technologies.

The key feature of this technology is Uplink Interference Cancellation, a component of advanced receiver designs for Node B technology. Uplink Interference Cancellation uses baseband processing to eliminate interference that can arise from multiple uplink data streams in a cell as well as from neighboring cells. For 2msec transmission time intervals (TTIs), Uplink Interference Cancellation can increase total HSUPA cell throughput by up to 60 percent, with median user data rate improvements of approximately 65 percent. Simulations suggest that systems with this feature can also support up to a 46 percent increase in cell VoIP traffic over an HSUPA Release 7 system and a 200 percent increase over Release 99 systems. This creates a better experience for the growing number of people using mobile devices to upload and share data-intensive photographs and videos, as well as to access popular Voice-over-IP (VoIP) services.

“Qualcomm and Huawei have a close relationship,” said Jing Wang, executive vice president of Qualcomm. “We’re pleased to have this opportunity to jointly demonstrate UMTS’ strong upgrade path and bring improved capacity and new opportunities to global customers.”

“Last year, Huawei won 44 commercial contracts to deploy UMTS/HSPA solutions. One of the success factors in gaining such a high level of trust from the world’s top operators is our ability to consistently deliver outstanding network performance through the joint development of world-class wireless technologies with industry leaders,” said Yu Chengdong, president of Huawei’s Wireless Network BU. “We are working closely with Qualcomm to bring more cutting-edge capabilities and products to mobile communications operators and customers all around the world.”
