A method for receiving, by a user equipment, UE, short downlink, DL, channels including a first short DL channel and a second short DL channel in a wireless communication system the method comprising: receiving (S1910) a DL channel including a Physical Downlink Control Channel, PDCCH, from a base station, BS, during a transmission time interval, TTI, wherein downlink control information, DCI, is received through the PDCCH; and receiving (S1920) the first short DL channel during a first short TTI, sTTI, and the second short DL channel during a second sTTI based on the DCI, wherein the first sTTI and the second sTTI are shorter than the TTI, wherein the first sTTI and the second sTTI are included in the TTI, wherein the DCI includes information on a first frequency resource for the first short DL channel and the second short DL channel, wherein the first short DL channel includes a first short Physical Downlink Control Channel, sPDCCH, and a first short Physical Downlink Shared Channel, sPDSCH, scheduled using the first sPDCCH, wherein the second short DL channel includes a second sPDCCH and a second sPDSCH scheduled using the second sPDCCH, wherein the first sPDCCH and the second sPDCCH are allocated to the first frequency resource, wherein the PDCCH is allocated to a second frequency resource different from the first frequency resource, wherein a first symbol of each of the first short DL channel and the second short DL channel includes a short Physical Control Format Indicator Channel, sPCFICH, wherein each sPCFICH indicates a resources region used for transmitting a control region for each of the first short DL channel and the second short DL channel, and wherein the sPCFICH is arranged only into an odd-numbered sTTIs of the first and second sTTIs. receiving (S1910) a DL channel including a Physical Downlink Control Channel, PDCCH, from a base station, BS, during a transmission time interval, TTI, wherein downlink control information, DCI, is received through the PDCCH; and receiving (S1920) the first short DL channel during a first short TTI, sTTI, and the second short DL channel during a second sTTI based on the DCI, wherein the first sTTI and the second sTTI are shorter than the TTI, wherein the first sTTI and the second sTTI are included in the TTI, wherein the DCI includes information on a first frequency resource for the first short DL channel and the second short DL channel, wherein the first short DL channel includes a first short Physical Downlink Control Channel, sPDCCH, and a first short Physical Downlink Shared Channel, sPDSCH, scheduled using the first sPDCCH, wherein the second short DL channel includes a second sPDCCH and a second sPDSCH scheduled using the second sPDCCH, wherein the first sPDCCH and the second sPDCCH are allocated to the first frequency resource, wherein the PDCCH is allocated to a second frequency resource different from the first frequency resource, wherein a first symbol of each of the first short DL channel and the second short DL channel includes a short Physical Control Format Indicator Channel, sPCFICH, wherein each sPCFICH indicates a resources region used for transmitting a control region for each of the first short DL channel and the second short DL channel, and wherein the sPCFICH is arranged only into an odd-numbered sTTIs of the first and second sTTIs. <EOS>
