Apparatus and method for relaying multiple links in a communication system
DCFirst Claim
1. 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,wherein the MLRS comprises at least one backhaul interface unit and at least one Mobile Station (MS) interface unit, and the MLRS forms the at least two independent backhaul links by allowing the at least two communication stations to share at least one backhaul interface unit, allowing the at least two communication stations to use independent backhaul interface units, or allowing each of the at least two communication stations to use at least two backhaul interface units.

Abstract
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.

12. 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,
wherein at least one backhaul interface unit and at least one Mobile Station (MS) interface unit are used for the multi-path control, and the at least two independent backhaul links are formed by allowing the at least two communication stations to share at least one backhaul interface unit, allowing the at least two communication stations to use independent backhaul interface units, or allowing each of the at least two communication stations to use at least two backhaul interface units.
