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: A method and apparatus for handling overlap of multiple channels in a wireless communication system is provided. A user equipment (UE), which operates in half-duplex frequency division duplex (FDD), determines that a periodic uplink (UL) transmission collides with a physical downlink shared channel (PDSCH) reception in a subframe, and performs either the periodic UL transmission or the PDSCH reception in the subframe. When the periodic UL transmission corresponds to a semi-persistent scheduled (SPS) physical uplink shared channel (PUSCH), the PDSCH reception is performed.

Abstract: A method and apparatus for transmitting a control channel to a machine-type communication (MTC) user equipment (UE) in a wireless communication system is provided. A base station (BS) configures a period of a control channel by using a first set of subframes which can be used for a MTC UE and a second set of subframes which cannot be used for the MTC UE, and transmits the control channel to the MTC UE in the first set of subframes within the period. A user equipment (UE) derives a starting subframe of the control channel among starting subframe sets of the control channel within the period of the control channel, and monitors the control channel from the starting subframe of the control channel.

Abstract: A user equipment attempts to decode decoding candidates and detects a physical downlink control channel (PDCCH) within time symbols from time symbol #0 to time symbol # N−1 for downlink control channel transmission in a transmission time interval (TTI). The user equipment receives downlink data on the basis of downlink control information carried by the PDCCH. Each of time symbol #0 to time symbol # N−1 includes a floor(X/N) number of decoding candidates. N is a maximum number of time symbols available for downlink control channel transmission in the TTI and is equal to or smaller than N, and X is a maximum number of decoding candidates for each TTI.
