Resource allocation method for backhaul link and access link in a wireless communication system including relay
First Claim
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 at least one backhaul link subframe among a fixed number of subframes in a time domain, wherein the at least one backhaul link subframe can be used for transmission from the BS to the RS;
configuring at least one subframe based on the configuration information; and
receiving a signal from the BS by using the at least one configured subframe,wherein the at least one configured subframe is selected among the at least one backhaul link subframe with an exception that predefined subframes of a radio frame are excluded,wherein when the radio flame includes ten subframes, the predefined subframes are a first, a fifth, a sixth and a tenth subframe of the radio flame when the BS and the RS are operated in frequency division duplex (FDD).

Abstract
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.

10. A relay station (RS) comprising:
-
a processor; and a radio frequency (RF) unit, coupled to the processor, for transmitting and receiving a radio signal, wherein the processor receives configuration information from a base station (BS), the configuration information indicating at least one backhaul link subframe among a fixed number of subframes in a time domain, wherein the at least one backhaul link subframe can be used for transmission from the BS to the RS, configures at least one subframe based on the configuration information, and receives a signal from the BS by using the at least one configured subframe, wherein the at least one configured subframe is selected among the at least one backhaul link subframe with an exception that predefined subframes of a radio frame are excluded, wherein when the radio frame includes ten subframes, the predefined subframes are a first, a fifth, a sixth and a tenth subframe of the radio frame when the BS and the RS are operated in frequency division duplex (FDD). - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
