Claim:
1. A method for communications controller operations, the method comprising: selecting a modulation and coding scheme for each of at least two relay nodes; encoding control data for each of the at least two relay nodes in accordance with the selected modulation and coding scheme; combining the encoded control data for the at least two relay nodes into a control channel data stream, wherein the encoded control data for each relay node comprises a downlink control message, wherein the control data for one of the at least two relay nodes further comprises an uplink control message, and wherein combining the encoded control data into a control channel data stream comprises: mapping a plurality of transmission resources for the control channel data stream into a plurality of physical resource blocks using a distributed virtual resource mapping rule, wherein the plurality of transmission resources are mapped to physical resource blocks that are non-contiguous in a frequency domain according to the distributed virtual resource mapping rule; rate-matching the control data in the control channel data stream with the plurality of physical resource blocks; and transmitting the plurality of physical resource blocks to the at least two relay nodes.
