Abstract: The present invention relates to a method for a terminal receiving an enhanced physical downlink control channel (EPDCCH) in a wireless access system supporting an unlicensed band, and the method may comprise the steps of: receiving, through an unlicensed-band cell (Ucell) configured in an unlicensed band, an EPDCCH comprising control information for scheduling the Ucell; and, on the basis of the control information, receiving downlink data from the Ucell. Here, if the EPDCCH is transmitted through a partial subframe (pSF), enhanced resource element groups (EREGs) constituting the EPDCCH are indexed from the start symbol of the pSF, and the pSF has a smaller size than one subframe, and the starting position of the pSF may not correspond to the subframe boundary of a primary cell (Pcell) configured in a licensed band.

Abstract: A method and apparatus for determining a length of a physical downlink shared channel (PDSCH) (or, a partial subframe) in a wireless communication system is provided. A user equipment (UE) detects at least one of starting orthogonal frequency division multiplexing (OFDM) symbol or ending OFDM symbol of a PDSCH in an unlicensed carrier, and determines the length of the PDSCH in the unlicensed carrier based on the at least one of the starting OFDM symbol or the ending OFDM symbol of the PDSCH in the unlicensed carrier. The UE may detect the at least one of starting OFDM symbol or ending OFDM symbol based on a physical downlink control channel (PDCCH) or a reference signal (RS) pattern.

Abstract: Disclosed is a method for a terminal to perform uplink (UL) transmission in a wireless communication system. In particular, the method comprises the steps in which a base station: receives information related to a sensing beam used for initiating channel occupancy time (COT); determines, on the basis of a quasi co-located (QCL) relationship between the sensing beam and the UL transmission, whether COT sharing is available; on the basis that the COT sharing is not available, senses a channel corresponding to the UL transmission on the basis of a type 1 channel access procedure (CAP) and performs the UL transmission on the basis of the channel being sensed as IDLE; and on the basis that the COT sharing is available, senses the channel on the basis of a type 2 CAP and performs the UL transmission within the COT on the basis of the channel being sensed as IDLE.
