1. An apparatus of an enhanced NodeB (eNB) comprising:

  • a transceiver arranged to communicate with a user equipment (UE) over an unlicensed channel in an unlicensed band; and

    processing circuitry arranged to;

    measure an interference power level within the unlicensed channel;

    determine proximity of the UE to the eNB;

    determine a transmit power level for a downlink transmission using the unlicensed channel from the eNB to the UE based on the interference power level;

    schedule the downlink transmission to the UE dependent on the proximity; and

    configure the transceiver to transmit the downlink transmission to the UE using the transmit power level according to the schedule.
