Apparatus and method for transmitting frame information in multi-hop relay broadband wireless access communication system
First Claim
1. A method for transmitting frame configuration information from an upper node in a wireless communication system using a relay scheme, the method comprising:
- transmitting, at the request of a lower relay station for an initial connection of the lower relay station, downlink section information for communication with the lower relay station for a relay service to the lower relay station; and
transmitting, after the initial connection with the lower relay station, frame configuration information for communication with the lower relay station for the relay service to the lower relay station through a downlink section identified in the downlink section information,wherein the downlink section information includes configuration information of the downlink section for communication with the lower relay station for the relay service.

Abstract
Provided is an apparatus and method for transmitting frame information in a wireless communication system using a relay scheme. In a method for transmitting frame information from an upper node in the wireless communication system, downlink section information for communication with the lower relay station for a relay service is transmitted to a lower relay station at the request of the lower relay station for an initial connection. After the initial connection, frame information for communication with the lower relay station for a relay service is transmitted to the lower relay station through the downlink section.

21. An apparatus of a relay station in a wireless communication system using a relay scheme, the apparatus comprising:
-
a receiver for receiving a signal from an upper node; a message processor for acquiring frame configuration information from a control message contained in the received signal; a message generator for generating a control message for transmitting the frame configuration information to a lower node; and a transmitter for transmitting the control message to a lower relay station, wherein the message processor acquires, at the initial connection with the upper node of the relay station, frame configuration information of a downlink section for communication with the upper node for a relay service from the control message received from the upper node through the receiver, and acquires, after the initial connection with the upper node, frame configuration information for communication with the upper node for the relay service and frame configuration information for communication with the lower relay station from the control message received through the downlink section, wherein the frame configuration information of the downlink section includes configuration information of the downlink section for communication with the lower relay station for the relay service. - View Dependent Claims (22, 23, 24)
