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 present invention relates to a wireless access system supporting an unlicensed band and provides methods for performing a channel access process for transmitting different types of signals, and devices supporting the same. According to one embodiment of the present invention, a method for transmitting different types of signals in a wireless access system supporting an unlicensed band can comprise the steps of: performing a first channel process (CAP) for transmitting a first type of signal; and transmitting a transmission burst including the first type of signal through the unlicensed band if it is determined that a serving cell (SCell) of the unlicensed band is in an idle state after performing the first CAP. At this time, at least one of first parameters for performing the first CAP can be set to be value less than that of second parameters for performing a second CAP for transmitting a second type of signal.
