the first UL/DL configuration is the UL/DL configuration 0, the UL/DL configuration 6, or a UL/DL configuration 1 if a UL/DL configuration for the scheduling cell is the UL/DL configuration 0 and the UL/DL configuration for the scheduled cell is the UL/DL configuration 6.

56. The BS of claim 44, wherein, if the scheduling policy of the UE is the half-duplex non-cross-carrier scheduling, the specific cell is a non-cross-carrier scheduled cell, a UL/DL configuration for a primary cell (PCell) is a UL/DL configuration 0 or 6, and a UL/DL configuration for the non-cross-carrier scheduled cell is the UL/DL configuration 0 or 6:

the first UL/DL configuration is the UL/DL configuration 0 or a UL/DL configuration 1 if a UL/DL configuration for the PCell is the UL/DL configuration 6 and the UL/DL configuration for the non-cross-carrier scheduled cell is the UL/DL configuration 0, and

the first UL/DL configuration is the UL/DL configuration 0 or 6 if a UL/DL configuration for the PCell is the UL/DL configuration 0 and the UL/DL configuration for the non-cross-carrier scheduled cell is the UL/DL configuration 6.
