Abstract: Information indicating one of possible PDSCH start subframes may be provided to the UE via the PDCCH. The PDSCH corresponding to the PDCCH may be transmitted/received starting from the indicated subframe. The possible PDSCH start subframes may be determined based on the ratio of the maximum number of PDCCH repetitions in the PDCCH search space and may be determined based on the ratio of the number of times related to the PDSCH repetition after the PDCCH search space.
