Downlink control channel signaling in wirless communication systems

A method in a wireless communication device, the method comprising:

• receiving a plurality of sub-frames, each sub-frame having time-frequency resource elements, at least one of the sub-frames having a control channel, the plurality of sub-frames forming a continuum of concatenated sub-frames;
• the control channel including a plurality of resource allocation fields, each resource allocation field associated with at least one corresponding sub-frame,
• each of the plurality of resource allocation fields indicating a resource assignment to the wireless communication device based on a channel quality report;
• and
• the plurality of resource allocation fields indicating resource assignments in sub-frames of the continuum of concatenated sub-frames;
• a sub-frame of the continuum of concatenated sub-frames including information indicating that at least some of the resource assignments are frequency diverse.
