Claim of US Patent No. 10,143,004

1. A method of receiving almost blank subframe (ABS) information by a first cell from a second cell in a wireless communication system, the method comprising:receiving an ABS pattern information element from the second cell; and
determining a subframe used as an ABS by the second cell from the ABS pattern information element,
wherein when the second cell is a cell to which enhanced interference management and traffic adaptation (eIMTA) is not applied, the first cell estimates the ABS pattern information element with reference to downlink (DL) subframes of an uplink/downlink (UL/DL) configuration on a system information block 1 (SIB1) of the second cell, and
wherein when the second cell is a cell to which the eIMTA is applied, the first cell estimates the ABS pattern information element with reference to DL subframes of a DL reference hybrid automatic repeat request (HARQ) UL/DL configuration of the second cell among the DL reference HARQ UL/DL configuration of the second cell and the UL/DL configuration on the SIB1 of the second cell.
