Patent ID: 8755326

Claim:
A method of transmitting and receiving a signal at a relay node (RN) in a wireless communication system, the method comprising: receiving a signal at the RN from a base station (BS) via a first region of a first downlink subframe on a downlink component carrier supporting first and second wireless communication schemes; and, transmitting a signal from the RN to of at least one first type user equipment (UE) using the first wireless communication scheme and at least one second type UE using the second wireless communication scheme via a second region of the first downlink subframe on the downlink component carrier, simultaneously with the receiving, and wherein the first and second regions are regions multiplexed by a frequency division multiplexing (FDM) scheme in the first downlink subframe, wherein the first region includes two regions multiplexed by the FDM scheme in the first downlink subframe and the two regions are located at both edges of a bandwidth of the downlink component carrier, wherein the first region is located at center frequency of the bandwidth of the downlink component carrier, wherein a guard band is located between each of the two regions and the second region.
