1. A base station transmitting control information for coordinating inter-heterogeneous cell interference, the base station comprising:

  • a signal receiving unit that receives an ABS (almost blank sub-frame) pattern configured to have transmission power controlled in a sub-frame determined considering interference with a heterogeneous eNB from an operation and management device that operates and manages the heterogeneous eNB;

    a system information generating unit that determines a first sub-frame where a PDCCH (physical downlink control channel) is transmitted and a second sub-frame where a PDSCH (physical downlink shared channel) scheduled by the PDCCH is transmitted based on the ABS pattern and generates separation information to indicate a separated distance between the first sub-frame and the second sub-frame;

    a downlink control information generating unit that generates downlink control information including a scheduling offset indicating the separated distance; and

    a signal transmitting unit that transmits the downlink control information through the PDCCH in the first sub-frame and transmits a paging message or system information through the PDSCH in the second sub-frame.
