Abstract: The present disclosure provides a method for receiving a synchronization signal/physical broadcast channel (SS/PBCH) block by a terminal in an unlicensed band. Particularly, the method may comprise: receiving an SS/PBCH block including an SS and a PBCH; detecting an index of a demodulation reference signal (DMRS) sequence for the PBCH; and on the basis of the index of the DRMS sequence, acquiring information relating to a time when an index of the SS/PBCH block and the SS/PBCH block are received, wherein the number of indices of the SS/PBCH block is smaller than or equal to the number of indices of the DMRS sequence, and the indices of the SS/PBCH block are cyclically mapped to the indices of the DMRS sequence.

Abstract: Provided are a method and a device for reporting channel state information (CSI) in a wireless communication system. A wireless device receives a first uplink grant for indicating that a transmission of a physical uplink shared channel (PUSCH) is triggered by a second uplink grant in a first subframe on a Licensed-Assisted Access (LAA) cell. The first uplink grant requests a report of an aperiodic CSI. The wireless device computes the aperiodic CSI based on a valid subframe no later than the first subframe in which the first uplink grant is received.

Abstract: The present invention relates to a wireless access system that supports an unlicensed band, and provides various methods for adjusting a contention window size and devices for supporting the same. As an embodiment of the present invention, a method for adjusting a contention window size (CWS) in a wireless access system supporting an unlicensed band may comprise the steps of: performing a channel access procedure; when, as a result of performing the channel access procedure, it is determined that a serving cell (Scell) in the unlicensed band is in an idle state, transmitting a transmission burst including a downlink signal; receiving HARQ-ACK information corresponding to the transmission burst; and adjusting the CWS on the basis of the HARQ-ACK information corresponding to the first subframe of the transmission burst.

Abstract: A method for receiving a signal by an apparatus in a wireless communication system is discussed. The method includes receiving, in a first time resource within a second time resource configured as 14 number of symbols, a physical channel carrying downlink control information within resource element groups (REGs), and receiving a physical downlink shared channel based on the downlink control information. Further, the REGs are indexed starting from a symbol included in the first time resource, and a starting boundary of the first time resource is determined independently from a starting boundary of the second time resource.
