A communication device comprising: a setting unit configured to set a repetition level corresponding to a number of repetitions of a physical downlink control channel; and a transmitting unit configured to transmit, to a user equipment, UE, the repetitions of the physical downlink control channel in subframes starting from a starting subframe with the set repetition level, characterized in that: the repetition level is one of multiple repetition levels including a first repetition level and a second repetition level that is larger than the first repetition level, an index of the starting subframe is one of starting subframe indexes, the starting subframe indexes being one of indexes of starting subframes in a first set of starting subframes defined for the first repetition level and indexes of starting subframes in a second set of starting subframes defined for the second repetition level, a second index interval between the indexes of the starting subframes in the second set of starting subframes is an integer multiple of a first index interval between the indexes of the starting subframes in the first set of starting subframes, and at least one of the indexes of the starting subframes is same in the first set of starting subframes and in the second set of starting subframe indexes, and the first index interval is equal to or larger than the first repetition level, and the second index interval is equal to or larger than the second repetition level. a setting unit configured to set a repetition level corresponding to a number of repetitions of a physical downlink control channel; and a transmitting unit configured to transmit, to a user equipment, UE, the repetitions of the physical downlink control channel in subframes starting from a starting subframe with the set repetition level, characterized in that: the repetition level is one of multiple repetition levels including a first repetition level and a second repetition level that is larger than the first repetition level, an index of the starting subframe is one of starting subframe indexes, the starting subframe indexes being one of indexes of starting subframes in a first set of starting subframes defined for the first repetition level and indexes of starting subframes in a second set of starting subframes defined for the second repetition level, a second index interval between the indexes of the starting subframes in the second set of starting subframes is an integer multiple of a first index interval between the indexes of the starting subframes in the first set of starting subframes, and at least one of the indexes of the starting subframes is same in the first set of starting subframes and in the second set of starting subframe indexes, and the first index interval is equal to or larger than the first repetition level, and the second index interval is equal to or larger than the second repetition level. the repetition level is one of multiple repetition levels including a first repetition level and a second repetition level that is larger than the first repetition level, an index of the starting subframe is one of starting subframe indexes, the starting subframe indexes being one of indexes of starting subframes in a first set of starting subframes defined for the first repetition level and indexes of starting subframes in a second set of starting subframes defined for the second repetition level, a second index interval between the indexes of the starting subframes in the second set of starting subframes is an integer multiple of a first index interval between the indexes of the starting subframes in the first set of starting subframes, and at least one of the indexes of the starting subframes is same in the first set of starting subframes and in the second set of starting subframe indexes, and the first index interval is equal to or larger than the first repetition level, and the second index interval is equal to or larger than the second repetition level.
