Embodiment Construction

[0073] In this document, the words "embodiment", "variation" and similar expressions are used to refer to a specific device, process or article of manufacture and not necessarily to the same device, process or article of manufacture. Therefore, "one embodiment" (or a similar expression) used in one place or situation may refer to a specific device, process or article of manufacture; the same or similar expression in different places may refer to a different device, process or article of manufacture. The expressions "alternative embodiment", "alternative variation" and similar terms are used to indicate one of many different possible embodiments or variations. The number of possible embodiments or variations is not necessarily limited to two or any other amount.

[0074] The word "exemplary" is used herein to mean "serving as an example, instance, or illustration." Any embodiment described herein as "exemplary" is not necessarily to be construed as preferred or advantageous ov...

Abstract

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.

Description

[0001] Claiming priority under 35 U.S.C. §119 [0002] The present application claims (1) Provisional Application No. 60 / 701,967 filed on July 21, 2005 entitled "Method and Apparatus for Multiplexing in Wireless Communications" and (2) filed on January 10, 2006 entitled Priority to Provisional Application No. 60 / 758,075 for "Some Elements for the Support of VoIP in GERAN." These provisional applications are assigned to the assignee of the present application and are expressly incorporated herein by reference, including all figures and tables, as if fully described herein. technical field [0003] The present invention relates generally to telecommunications, and more particularly to methods, apparatus and articles of manufacture for multiplexing multiple users and supporting feedback in a cellular radio network. Background technique [0004] Modern communication systems are expected to provide reliable data transmission for a variety of applications, including voice and da...
