Claim:
1. A method for communicating with a non-relay wireless node, the method comprising: selecting, by a communications controller, between a control region and a data region of a subframe for mapping of modulated control information for the non-relay wireless node; determining, by the communications controller in response to the data region being selected, a first resource assignment parameter derived from an identifier; transmitting, by the communications controller to the non-relay wireless node, configuration information including first information indicating the data region of the subframe is used for the modulated control information for the non-relay wireless node, wherein the modulated control information is scrambled in accordance with second information of the configuration information; generating, by the communications controller in accordance with the configuration information, a first wireless node-specific demodulation reference signal sequence for demodulating the modulated control information for the non-relay wireless node; mapping, by the communications controller in response to the data region being selected, using the first resource assignment parameter, the first wireless node-specific demodulation reference signal sequence for demodulating the modulated control information for the non-relay wireless node, onto a first resource located in the data region of the subframe; mapping, by the communications controller in response to the data region being selected, the modulated control information onto a second resource located in the data region of the subframe; mapping, by the communications controller, a second wireless node-specific demodulation reference signal sequence for demodulating data, onto a third resource located in the data region of the subframe, wherein the first wireless node-specific demodulation reference signal sequence is different from the second wireless node-specific demodulation reference signal sequence; mapping, by the communications controller, the data onto a fourth resource located in the data region of the subframe; and transmitting, by the communications controller, the subframe to the non-relay wireless node.
