Method of indicating a control channel in a wireless access system, base station for the same and user equipment for the same

In transmitting a control channel of a 1st base station in a wireless communication system, a method of transmitting the control channel, comprising the steps of:

• receiving a semi-static ABRB (almost blank RB) pattern for E-PDCCH (enhanced-physical downlink control channel) of a 2nd base station containing a downlink scheduling information in a data region by RRC (radio resource control);
• and
• assigning E-PDCCH containing a downlink scheduling information of the 1st base station to a corresponding blank data region resource based on the ARBR (almost blank resource block) pattern from the 2nd base station.

A 1st base station, of which control channel is transmitted in a wireless communication system, comprising:

• a radio frequency unit;
• and
• a processor configured to control the radio frequency unit, the processor controlling the radio frequency unit to receive E-PDCCH (enhanced-physical downlink control channel) including a downlink scheduling information in a data region from a 2nd base station, the processor assigning E-PDCCH including a downlink scheduling information of the 1st base station to the data region based on the downlink scheduling information received from the 2nd base station, the processor controlling the radio frequency unit to transmit the downlink scheduling information of the 1st base station to the 2nd base station.
