1. A method of wireless communication, comprising:
- sending from a first node a downlink control signal originating from the first node directly to a wireless device using a first communication link;
sending from said first node a downlink data signal directly to said wireless device using said first communication link;
receiving by said first node an uplink control signal indirectly from said wireless device via a second node using a third communication link, said uplink control signal associated with said downlink data signal;
receiving by said first node another downlink control signal originated by said second node directly from said second node, wherein said another downlink control signal includes information scheduling an uplink transmission from said wireless device to said second node using a second communication link; and
forwarding by said first node said another downlink control signal received from said second node via said third communications link to said wireless device using said first communication link.
