Embodiment Construction

[0019] A system and method for minimizing control overhead in a multi-carrier wireless communication network using time-frequency resources is disclosed. In some embodiments, one or more regions of the time-frequency resources are designated for specific applications, such as regions dedicated to Voice over IP (VoIP) applications. By grouping similar types of applications together in a region, the number of bits required for mapping a packet stream to a portion of a time-frequency resource can be reduced. In some embodiments, a modular encoding scheme associated with the packet flow may be selected to further reduce the amount of control information required.

[0020] In some embodiments, packets may be classified for transmission according to application type, QoS parameters, and other characteristics. Application Connection Specific Identifiers (ACIDs) can also be assigned to packet flows. Both approaches can reduce the overhead associated with managing multiple applicatio...

Abstract

A method and system for minimizing the control overhead in a multi-carrier wireless communication network that utilizes a time-frequency resource is disclosed. In some embodiments, one or more zones in the time-frequency resource are designated for particular applications, such as a zone dedicated for voice-over-IP (VoIP) applications. By grouping applications of a similar type together within a zone, a reduction in the number of bits necessary for mapping a packet stream to a portion of the time-frequency resource can be achieved. In some embodiments, modular coding schemes associated with the packet streams may be selected that further reduce the amount of necessary control information. In some embodiments, packets may be classified for transmission in accordance with application type, QoS parameters, and other properties. In some embodiments, improved control messages may be constructed to facilitate the control process and minimize associated overhead.

Description

[0001] This application is a divisional application of the invention patent application with application number 200680009811.1 and the title of the invention is "Method and system for multi-carrier packet communication with reduced overhead". The international filing date of the invention patent application with application number 200680009811.1 is September 2006 International Application No. PCT / US2006 / 038149, dated September 28, and claims the benefit of US Provisional Patent Application No. 60 / 721,451, filed September 28, 2005. technical field [0002] The disclosed technology relates generally to wireless communications and, more specifically, to multi-carrier packet communication networks. Background technique [0003] For wireless communication systems, bandwidth efficiency is one of the most important system performance factors. In packet-based data communications, application payloads usually have different sizes and different quality of service (QoS) requirements du...
