1. An apparatus of a relay node (RN) comprising:

  • processing circuitry and transceiver circuitry configured to;

    demodulate a PDCCH to decode downlink control information (DCI), the DCI providing an indication as to what subframes can be used for by the RN for reception and transmission of downlink or uplink data, and re-transmission to a user equipment (UE),wherein downlink transmissions from an evolved Node B (eNB) to the RN are received during a first plurality of subframes, and downlink transmissions from the RN to the UE are transmitted during a second plurality of subframes in accordance with the indication provided in the DCI;

    receive downlink transmissions from the eNB during the first plurality of subframes; and

    retransmit the downlink transmissions to the UE during the second plurality of subframes, wherein the first plurality of subframes are time multiplexed with the second plurality of subframes.
