An apparatus and method for transmitting and receiving control data and user data between multiple communication stations using multiple backhaul links in a communication system, in which a Multi-Link Relay Station (MLRS) generates multiple backhaul links for data transmission/reception between multiple communication stations, and provides a multi-homing service for mobile stations using the generated multiple backhaul links. The MLRS may also support a handover for mobile stations using the multiple backhaul links. The use of multiple backhaul links facilitates efficient transmission/reception of control data and/or user data between multiple base stations or multiple relay stations.
A Multi-Link Relay Station (MLRS) in a communication system, adapted to perform a multi-path control to provide a communication service through at least two independent backhaul links connecting simultaneously at least two communication stations,
A method of performing a multi-path control in a communication system by providing a communication service through at least two independent backhaul links connecting simultaneously at least two communication stations,

This application makes reference to and claims all benefits from an application entitled APPARATUS AND METHOD FOR RELAYING MULTIPLE LINKS IN A COMMUNICATION SYSTEM filed in the Korean Intellectual Property Office on Feb. 2, 2010 and there duly assigned Ser. No. PCT/KR2010/000641, which in turn claims a priority to an earlier Korean Patent Application No. 10-2009-0008187 Filed on Feb. 2, 2009 and Korean Patent Application 10-2010-0008792 filed on Jan. 29, 2010.
Next-generation communication systems have developed to offer a variety of high-speed, high-capacity services to Mobile Stations (MSs). In particularly, the next-generation communication systems consider using a multi-hop relay scheme for a variety of reasons such as the expansion of Base Station (BS) coverage and the increase in BS capacity. In other words, the next-generation communication systems consider using the multi-hop relay scheme because this scheme may be efficiently applied to the change in wireless network environments and may actively cope with the change in network environments such as addition of BSs.
The next-generation communication systems now consider only the scheme of relaying signals using a single backhaul link. In other words, the next-generation communication systems now consider only the Relay Stations (RSs) that relay signals using a single backhaul link. However, transmitting/receiving control data and user data between multiple BSs or multiple RSs using a single backhaul link decreases in its efficiency due to many restrictions.
The above and other aspects, features and advantages of certain exemplary embodiments of the present invention will be more apparent from the following description taken in conjunction with the accompanying drawings, in which:
FIG. 1 schematically shows a configuration of a multi-path relay system according to an embodiment of the present invention;
FIG. 2 schematically shows a method for generating backhaul links by sharing the same resource by an MLRS in a multi-path relay system according to an embodiment of the present invention;
Throughout the drawings, the same drawing reference numerals will be understood to refer to the same elements, features and structures.
Exemplary embodiments of the present invention will be described herein below in detail with reference to the accompanying drawings. The embodiments described herein and structures shown in the drawings are merely illustrative and do not cover every technical spirit of the invention. Therefore, it will be understood that various modifications which can substitute for the embodiments can be made at the time of filing the present application.
The present invention provides an apparatus and method for relaying multiple links in a communication system. In the following description of the present invention, frequency resources are considered as an example of resources applied in an apparatus and method for relaying multiple links. However, the resources may include time resources, code resources and spatial resources, as well as the frequency resources.
