FIELD: radio engineering, communication.
SUBSTANCE: invention relates to wireless communication. A method and apparatus for allocating control channels of a relay within a backhaul subframe in a wireless communication system are provided. The method of allocating control channel resources includes steps of: grouping relays according to channel conditions; transmitting resource group information in the same resource group allocated to use the same transmission mode for the relays belonging to the same relay group; transmitting a control channel message to the relays according to the allocated resource; and transmitting data to the relays according to the control channel message.
EFFECT: improving efficiency by reducing the number of blind decoding instances in a relay node.
