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: The embodiments of the present invention relate to a wireless access system supporting an unlicensed band and to methods for generating a discovery signal (DRS), methods for generating and transmitting a channel state information reference signal included in the DRS, and devices for supporting same. The method for transmitting a discovery signal (DRS) including a channel state information reference signal (CSI-RS) in a wireless access system supporting an unlicensed band, according to one embodiment of the present invention, may comprise the steps of: initiating, in subframe n (SF #n), a listen-before-talk (LBT) procedure for checking whether the unlicensed band is idle or not; if an LBT procedure succeeds in SF #n+k, generating a sequence for transmitting the CSI-RS on the basis of the subframe index j indicating SF #j; and transmitting the DRS, including the CSI-RS, in SF #n+k. Herein n, k, and j are preferably integers greater than or equal to 0 and less than or equal to 9.

Abstract: A method for downlink control information (DCI) transmission/reception is provided. The method for DCI transmission comprises: receiving, by a user equipment, a narrowband physical downlink control channel (N-PDCCH) carrying the DCI. The N-PDCCH is received using at least one of two control channel element (CCEs) on the 1 resource block (RB) only. A first CCE of the two CCEs occupies 6 subcarriers of the lowest indices among the 12 subcarriers and a second CCE of the two CCEs occupies 6 subcarriers of the highest indices among the 12 subcarriers.
