In some examples, a method of transmitting data in a radio communication system is described. The method can include dividing data intended for a communication receive node into a high priority code stream and a low priority code stream. The method can also include transmitting the high priority code stream to the communication receive node and a relay node. The method can also include transmitting the low priority code stream to the communication receive node. The relay node may be configured to receive, amplify and forward the high priority code stream to the communication receive node. The communication receive node may be configured to receive the high priority code stream substantially during first time intervals and may be further configured to receive both the low priority code stream and the amplified high priority code stream substantially during second time intervals interleaved with the first time intervals.
