Resource allocation method for backhaul link and access link in a wireless communication system including relay
A resource allocation method of a relay station in a wireless communication system employing the relay station is provided. The method includes: receiving information on a resource allocation pattern for an access link and a backhaul link of a first frequency band; and determining a resource allocation pattern for an access link and a backhaul link of a second frequency band on the basis of the resource allocation pattern of the first frequency band, wherein the first frequency band is any one of an uplink frequency band and a downlink frequency band, and the second frequency band is a remaining one of the uplink frequency band and the downlink frequency band.
1. A method of communicating in a wireless communication system, performed by a relay station (RS), the method comprising:
receiving configuration information from a base station (BS), the configuration information indicating a backhaul link subframe, the backhaul link subframe being used for a transmission from the BS to the RS;
configuring a subframe as the backhaul link subframe, based on the configuration information; and
receiving a signal from the BS by using the backhaul link subframe,
wherein the backhaul link subframe is configured among subframes included in a radio frame with an exception that predefined subframes of the radio frame are excluded,
wherein, when the radio frame includes ten subframes, the predefined subframes are a first, a second, a sixth, and a seventh subframe of the radio frame when the BS and the RS are operated in time division duplex (TDD).
2. The method of claim 1 , further comprising:
connecting with a user equipment (UE); and
transmitting a signal to the UE in the first, the second, the sixth, and the seventh subframes.
3. The method of claim 1 , wherein the configuration information is received via a higher layer signal.
4. The method of claim 1 , wherein the configuration information indicates the backhaul link subframe among a fixed number of subframes in a time domain.
5. The method of claim 4 , wherein the fixed number is 10.
6. A relay station (RS), comprising:
a radio frequency (RF) unit configured to transmit and receive a radio signal; and
a processor coupled to the RF unit and configured to:
receive configuration information from a base station (BS), the configuration information indicating a backhaul link subframe, the backhaul link subframe being used for a transmission from the BS to the RS;
configure a subframe as the backhaul link subframe, based on the configuration information; and
receive a signal from the BS by using the backhaul link subframe,
wherein the backhaul link subframe is configured among subframes included in a radio frame with an exception that predefined subframes of the radio frame are excluded,
wherein, when the radio frame includes ten subframes, the predefined subframes are a first, a second, a sixth, and a seventh subframe of the radio frame when the BS and the RS are operated in time division duplex (TDD).
7. The RS of claim 6 , wherein the processor is further configured to:
connect with a user equipment (UE); and
transmit a signal to the UE in the first, the second, the sixth, and the seventh subframes.
8. The RS of claim 6 , wherein the configuration information is received via a higher layer signal.
9. The RS of claim 6 , wherein the configuration information indicates the backhaul link subframe among a fixed number of subframes in a time domain.
10. The RS of claim 9 , wherein the fixed number is 10.
