Abstract:
1. A method for transmitting and receiving a signal in a relay node operating on multiple carriers, the method comprising: receiving a control channel from a base station; determining a type of the control channel, wherein the type of the control channel is determined depending on whether a component carrier through which the control channel is received is an in-band component carrier or an out-band component carrier; determining an in-band operation mode or an out-band operation mode based on the determined type of the control channel; and transmitting and receiving the signal to and from at least one of the base station or a user equipment according to the determined operation mode, wherein the multiple carriers include one or more in-band component carriers and one or more out-band component carriers, wherein the control channel is a physical downlink control channel (PDCCH) when the control channel is received through the out-band component carrier, and wherein the control channel is a relay-PDCCH (R-PDCCH) when the control channel is received through the in-band component carrier.
