US Patent Issued to QUALCOMM on Jan. 11 for "Multiplexing and Feedback Support for Wireless Communication Systems" (American, Danish, Italian Inventors)

ALEXANDRIA, Va., Jan. 12 -- United States Patent no. 7,869,417, issued on Jan. 11, was assigned to QUALCOMM Inc. (San Diego).

"Multiplexing and Feedback Support for Wireless Communication Systems" was invented by Aleksandar Damnjanovic (Del Mar, Calif.), Lorenzo Casaccia (Rome) and Niels Peter Skov Andersen (Roskilde, Denmark).

According to the abstract released by the U.

S. Patent & Trademark Office: "A control scheme using packet headers allows GSM EDGE Radio Access Network (GERAN) systems to increase spectral efficiency through multiplexing techniques, such as superposition coding, multi-user packet transmission, joint detection, and/or joint decoding. A fast feedback scheme for GERAN allows Voice over Internet Protocol (VoIP) frames to be transmitted over GERAN air interfaces without excessive feedback latency. As a result, Hybrid Automatic Repeat-reQuest (H-ARQ) acknowledgements may be timely provided for end-to-end VoIP calls that traverse GERAN air interfaces. Additionally, Incremental Redundancy H-ARQ and link quality feedback latencies are decreased."

The patent was filed on July 19, 2006, under Application No. 11/489,918.
