Embodiment Construction

[0030] Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. In the following description, well-known functions or constructions are not described in detail since they would obscure the invention in unnecessary detail. Also, the terms used herein are defined according to the functions of the present invention. These terms may depend on the meaning and usage of users or operators. The terminology used herein must be understood based on the description herein.

[0031] The present invention provides a scheme for a signaling procedure for removing MS information from one or more RSs on an MS data transmission path in a multi-hop relay BWA communication system. For example, the multi-hop relay BWA communication system adopts OFDM or OFDMA scheme. Therefore, the multi-hop relay BWA communication system can use multiple sub-carriers to send physical channel signals, thereby enabling high-rate data transmission. ...

Abstract

Disclosed is an apparatus and method for releasing MS information in a wireless access communication system using a multi-hop relay scheme. In a method for a communication operation of a BS, when a data transmission path of an MS changes, one or more RSs from which information about the MS is to be removed are determined. Thereafter, a path removal message is generated and the path removal message is transmitted to the one or more RSs.

Description

[0001] priority [0002] This application claims priority under 35 U.S.C § 119 to Application Serial No. 2007-23032 filed March 8, 2007 with the Korean Intellectual Property Office, the contents of which are hereby incorporated by reference in their entirety. technical field [0003] The present invention generally relates to a wireless access communication system adopting a multi-hop relay scheme, and in particular, relates to a signaling for removing mobile station information from a relay station on a multi-hop path in a wireless access communication system Apparatus and methods of the process. Background technique [0004] Extensive research is underway to provide various quality of service (QoS) features with data rates around 100 Mbps in advanced fourth generation (4G) communication systems. 4G communication systems are evolving to provide mobility, high data rate transmission, and high QoS in Broadband Wireless Access (BWA) communication systems such as Local Area Ne...
