The PDSCH can be transmitted to the user equipment starting from subframe n+k, which is the kth subframe after the last subframe n−1 in the first subframe bundle, wherein k is an integer bigger than 0. The first subframe bundle may begin from a predetermined or fixed position. ## Claims ### Claim 1 A method for receiving, by a user equipment, downlink data, the method comprising: repeatedly receiving, by the user equipment, a physical downlink control channel, PDCCH, carrying downlink control information across N consecutive subframes, where N is an integer greater than 1; and repeatedly receiving, by the user equipment, a physical downlink shared channel, PDSCH, carrying the downlink data, across D consecutive subframes starting from a subframe n+k after a subframe n in which the PDCCH is last received, based on the downlink control information, where D is a positive integer, wherein k is an integer greater than 1. ### Claim 2 (depends on 1) The method according to claim 1, further comprising: receiving, by the user equipment, a higher layer signal including information on a maximum number of repetitions for the PDCCH, wherein N is less than or equal to the maximum number of repetitions for the PDCCH. ### Claim 3 (depends on 1) The method according to claim 1, further comprising: receiving, by the user equipment, information on a start of the N consecutive subframes. ### Claim 4 (depends on 1) The method according to claim 1, wherein the repeatedly received PDCCHs are received using a same control channel element, CCE, resource within the N consecutive subframes. ### Claim 5 A method for transmitting, by a base station, downlink data, the method comprising: repeatedly transmitting, by the base station, a physical downlink control channel, PDCCH, carrying downlink control information across N consecutive subframes, where N is an integer greater than 1; and repeatedly transmitting, by the base station, a physical downlink shared channel, PDSCH, carrying the downlink data, across D consecutive subframes starting from a subframe n+k after a subframe n in which the PDCCH is last transmitted, based on the downlink control information, where D is a positive integer, wherein k is an integer greater than 1. ### Claim 6 (depends on 5) The method according to claim 5, further comprising: transmitting, by the base station, a higher layer signal including information on a maximum number of repetitions for the PDCCH, wherein N is less than or equal to the maximum number of repetitions for the PDCCH. ### Claim 7 (depends on 5) The method according to claim 5, further comprising: transmitting, by the base station, information on a start of the N consecutive subframes. ### Claim 8 (depends on 5) The method according to claim 5, wherein the repeatedly transmitted PDCCHs are transmitted using a same control channel element, CCE, resource within the N consecutive subframes. ### Claim 9 A user equipment for receiving downlink data, the user equipment comprising: a transceiver, and a processor configured to control the transceiver to: repeatedly receive a physical downlink control channel, PDCCH, carrying downlink control information across N consecutive subframes, where N is an integer greater than 1; and repeatedly receive a physical downlink shared channel, PDSCH, carrying the downlink data, across D consecutive subframes starting from a subframe n+k after a subframe n in which the PDCCH is last received, based on the downlink control information, where D is a positive integer, wherein k is an integer greater than 1. ### Claim 10 (depends on 9) The user equipment according to claim 9, wherein the processor is configured to control the transceiver to receive a higher layer signal including information on a maximum number of repetitions for the PDCCH, wherein N is less than or equal to the maximum number of repetitions for the PDCCH. ### Claim 11 (depends on 9) The user equipment according to claim 9, wherein the processor is configured to control the transceiver to receive information on a start of the N consecutive subframes. ### Claim 12 (depends on 9) The user equipment according to claim 9 wherein the repeatedly received PDCCHs are received using a same control channel element, CCE, resource within the N consecutive subframes. ### Claim 13 A base station for transmitting downlink data, the base station comprising: a transceiver, and a processor configured to control the transceiver to: repeatedly transmit a physical downlink control channel, PDCCH, carrying downlink control information across N consecutive subframes, where N is an integer greater than 1; and repeatedly transmit a physical downlink shared channel, PDSCH, carrying the downlink data, across D consecutive subframes starting from a subframe n+k after a subframe n in which the PDCCH is last transmitted, based on the downlink control information, where D is a positive integer, wherein k is an integer greater than 1. ### Claim 14 (depends on 13) The base station according to claim 13, wherein the processor is configured to control the transceiver to transmit a higher layer signal including information on a maximum number of repetitions for the PDCCH, wherein N is less than or equal to the maximum number of repetitions for the PDCCH. ### Claim 15 (depends on 13) The base station according to claim 13, wherein the processor is configured to control the transceiver to transmit information on a start of the N consecutive subframes.
