Downlink control channel for relay resource allocation

An apparatus for wireless communications, comprising:

• at least one processor configured to:
• allocate resources of a backhaul link between a donor base station and a relay base station to the relay base station for communicating with the donor base station;
• and
• transmit signaling on a control channel indicating the allocated resources to the relay base station, wherein the signaling on the control channel is transmitted on a subset of physical resource blocks (PRBs) of subframes assigned for downlink communications on the backhaul link, and wherein the control channel is mapped to the subset of PRBs based on a resource allocation type for downlink communications on the backhaul link;
• and
• a memory coupled with the at least one processor.

• and
• communicate with the donor base station over the backhaul link using the allocated resources;
• and
• a memory coupled with the at least one processor.
