Abstract: A method of receiving a Physical Downlink Shared Channel (PDSCH) includes: receiving, in a first bandwidth part (BWP), a downlink control information (DCI) including (i) first information that indicates switching an active BWP from the first BWP to a second BWP, and (ii) second information related to scheduling at least one transport block (TB) for the PDSCH; and receiving, in the second BWP, the PDSCH based on the first information and the second information. Based on a number of TBs in a first group of TBs that can be scheduled through the second information being equal to one, and based on a number of TBs in a second group of TBs that can be scheduled for the second BWP being equal to two: among the second information related to scheduling the at least one TB, information related to a second TB among the second group of TBs is disabled.

Abstract: The present invention relates to a wireless access system supporting an unlicensed band, various methods for adjusting a contention window size, methods for performing a carrier sensing process in a single engine and a multi-engine, and an apparatus supporting the same. As one embodiment of the invention, a method for adjusting a contention window size (CWS) in a wireless access system supporting an unlicensed band may comprise: a step of setting a contention window size (CWS) necessary for performing a channel access process for each of priority classes; a step of performing a channel access process for a particular priority class in a channel in an unlicensed band on the basis of the set CWS; a step of performing a downlink transmission related to the particular priority class if it is determined that the channel in the unlicensed band is in an idle state as a result of the channel access process; and a step of making adjustments for all CWS' of priority classes if a triggering event, which relates to a downlink transmission and increases or reduces the CWS for the particular priority class, occurs.

Abstract: A method of transmitting uplink (UL) control information for a user equipment (UE) for supporting a plurality of TTI lengths, a plurality of subcarrier spacing, or a plurality of processing times in a wireless communication system is performed by the UE and includes mapping the UL control information to a radio resource in a TTI including two or three symbols, the UL control information including HARQ-ACK, a rank indicator (RI), a channel quality indicator (CQI), or a precoding matrix indicator (PMI), and transmitting the UL control information to a base station, wherein, when there is no symbol to which a DMRS is mapped in the TTI, HARQ-ACK is mapped to a first symbol in the TTI in descending order from a highest frequency index resource element (RE) and the RI is mapped to the other symbol in the TTI in descending order from a highest frequency index RE.

Abstract: The present invention relates to signal transmission and reception method and device by an equipment which is dual-connected to a first radio access technology (RAT) and a second RAT in a wireless communication system. The method comprises the steps of: a first signal in accordance with a first RAT and a second signal in accordance with a second RAT being scheduled separately timewise; and transmitting and receiving the first signal and the second signal. The operation for the second signal is determined on the basis of whether or not the second signal reception is scheduled in a first time domain for transmitting the first signal. The UE is capable of communicating with at least one of another UE, a UE related to an autonomous driving vehicle, a base station or a network.
