Abstract: A method and apparatus for transmitting/receiving a downlink channel in a wireless communication system are provided. A physical downlink control channel (PDCCH) can be transmitted using one or more resource element groups (REGs) among a plurality of REGs in a transmission time interval (TTI). Each of the plurality of REGs occupies 12 consecutive resource elements (REs) belonging to a physical resource block (PRB) along a frequency domain within an orthogonal frequency division multiplexing (OFDM) symbol with or without a reference signal (RS) in the TTI.

Abstract: Multiple short transmission time intervals (TTIs), each of which is shorter than 1 ms, may be configured in a subframe. A user equipment (UE) may transmit a demodulation reference signal (DM-RS) which is shared among different UEs to an eNodeB (eNB). In this case, the DM-RS may be transmitted in a reference TTI, which is one short TTI among the multiple short TTIs, and the reference TTI may be indicated by downlink control information (DCI) received from the eNB. Alternatively, a UE may transmit the DM-RS which is shared among different short TTIs to the eNB.

Abstract: According to the present invention, a base station transmits zero-power information with respect to a downlink control channel, sets some of downlink control channel candidates in a slot at zero-power in accordance with the zero-power information, and transmits the downlink control channel via the downlink control channel candidates User equipment receives the zero-power information with respect to the downlink control channel and receives the downlink control channel via the downlink control channel candidates in the slot. The user equipment detects the downlink control channel by assuming, on the basis of the zero-power information, that the some of downlink control channel candidates are zero-power.

Abstract: The transmission apparatus maps a plurality of code blocks obtained from data to a time-frequency resource, and transmits the plurality of code blocks therefrom. The time-frequency resource comprises L number of time symbols in the time domain, where L is an integer greater than 1. Each of the L number of time symbols comprises one or more different code blocks from among the plurality of code blocks. The plurality of code blocks is mapped in the time-frequency resource so that one complete code block is one time symbol.
