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: A method of performing wireless communication by a first device is proposed. The method includes receiving downlink control information (DCI) related to first sidelink from a base station, and transmitting, to the base station, a confirmation message for reception of the DCI related to the first sidelink through a first medium access control (MAC) control element (CE). For example, the first MAC CE may include at least one index information related to at least one semi-persistent scheduling (SPS) configuration activated or released by the DCI.

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: In an embodiment of the present disclosure, proposed is a method in which a first UE transmits a signal to a second UE in a wireless communication system, the method including: a step in which the first UE receives a first signal from the second UE; a step in which the first UE acquires the distance between the first UE and the second UE on the basis of the received first signal; a step in which the first UE selects, on the basis of the calculated distance, a numerology for transmitting a second signal, or a transmit resource in which the numerology is set; and a step in which the first UE transmits the second signal to the second UE on the basis of the selected numerology or the transmit resource. 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.
