Abstract:
1. A method for communications controller operations, the method comprising: combining control data for each relay node of a plurality of relay nodes into a control channel data stream for a data region of a frame structure, wherein the control data for each relay node comprises a downlink control message, wherein the control data for one or more relay nodes of the plurality of relay nodes further comprises an uplink control message, and wherein combining the control data into the control channel data stream comprises: mapping a plurality of first transmission resources for the downlink portion of the control channel data stream to a plurality of first physical resource blocks using a distributed virtual resource mapping rule, wherein the plurality of first transmission resources are mapped to first physical resource blocks that are non-contiguous in a frequency domain; separately mapping a plurality of second transmission resources for the uplink portion of the control channel data stream to a plurality of second physical resource blocks using the distributed virtual resource mapping rule, wherein the plurality of second transmission resources are mapped to second physical resource blocks that are non-contiguous in the frequency domain; rate-matching the control data in the control channel data stream with the plurality of first and second physical resource blocks; and transmitting the plurality of first and second physical resource blocks to the plurality of relay nodes.
