Method of operating relay station in wireless communication system
First Claim
1. A method for a Hybrid Automatic Repeat reQuest (HARQ) operation in a wireless communication system, the method performed by a base station (BS) and comprising:
- transmitting subframe configuration information to a relay station (RS);
transmitting data to the RS in a downlink subframe configured based on the subframe configuration information; and
receiving acknowledgement/negative acknowledgement (ACK/NACK) information for the data in an uplink subframe,wherein a first downlink transmission, from the BS to the RS, and a second downlink transmission, from the RS to a user equipment (UE), are performed at different times and in a downlink frequency band,wherein the downlink subframe for transmitting the data to the RS is configured per a specific number of subframes with an exception of a first downlink subframe, a fifth downlink subframe, a sixth downlink subframe and a tenth downlink subframe of a frame, andwherein the frame comprises 10 downlink subframes.

Abstract
A method of operating a relay station in a wireless communication system is provided. The method includes operating in a first mode comprising a first sub-mode and a second sub-mode, in the first sub-mode a first downlink and a first uplink between a base station and the relay station being simultaneously activated, in the second sub-mode a second downlink and a second uplink between the relay station and a mobile station being simultaneously activated, and operating in a second mode comprising a third sub-mode and a fourth sub-mode, in the third sub-mode the first downlink and the second uplink being simultaneously activated, in the fourth sub-mode the first uplink and the second downlink being simultaneously activated.

5. A base station (BS) comprising:
-
a transmitter and a receiver; and a processor, operatively coupled to the transmitter and receiver, wherein the processor is configured to; control the transmitter to transmit subframe configuration information to a relay station (RS), control the transmitter to transmit data to the RS in a downlink subframe configured based on the subframe configuration information, and control the receiver to receive acknowledgement/negative acknowledgement (ACK/NACK) information for the data in an uplink subframe, wherein a first downlink transmission, from the BS to the RS, and a second downlink transmission, from the RS to a user equipment (UE), are performed at different times and in a downlink frequency band, wherein the downlink subframe for transmitting the data to the RS is configured per a specific number of subframes with an exception of a first downlink subframe, a fifth downlink subframe, a sixth downlink subframe and a tenth downlink subframe of a frame, and wherein the frame comprises 10 downlink subframes. - View Dependent Claims (6, 7, 8)
