Claim of US Patent No. 10,602,538

1. A method of receiving a signal by a user equipment (UE) configured with a plurality of cells, the method comprising:receiving a first uplink-downlink subframe configuration for enhanced interface mitigation and traffic adaptation (eIMTA) fallback, contained in a system information block type 1 (SIB 1), indicating that a first uplink subframe is a subframe which corresponds to one of uplink subframes;
receiving a hybrid automatic repeat request (HARQ) reference configuration for the eIMTA fallback indicating that the first uplink subframe is a subframe which corresponds to one of downlink subframes;
performing blind decoding on a downlink grant by assuming a first uplink subframe of a first cell with a time division duplex (TDD) frame structure among the plurality of cells as a virtual downlink subframe; and
receiving downlink data via a second cell, residing on an unlicensed band, among a plurality of the cells, when the downlink grant for the second cell is detected during the blind decoding.
