Abstract: Provided are a PDCCH monitoring method and device of a DRX-configured terminal in a wireless communication system. In the method, if a monitoring occasion is present in a monitoring window for monitoring DCI (WUS) comprising a wake-up indication, the WUS is monitored in the monitoring occasion and, if the WUS is detected, the relevant operation is performed in a DRX ON duration on the basis of same. The WUS can indicate whether or not to wake up from a plurality of DRX cycles. Also, the WUS can indicate various configurations in accordance with the length of the DRX cycles. If the monitoring occasion is not present in the monitoring window, the terminal wakes up from a DRX cycle linked to the monitoring occasion and performs PDCCH monitoring for a general DCI detection not comprising a wake-up indication.

Abstract: A method for transmitting signals by a user equipment (UE) in a multi input multi output (MIMO) communication system is disclosed. The method comprises steps of receiving two or more MIMO layer configurations per bandwidth part (BWP); receiving a medium access control (MAC) control element (CE) indicating a first MIMO layer configuration for a downlink reception via a first BWP and a second MIMO layer configuration for an uplink transmission via a second BWP among the two or more MIMO layer configurations; and transmitting and receiving signals based on the first and second MIMO layer configurations.

Abstract: Provided are a method for reporting a power headroom and an apparatus using the same. The apparatus computes and reports a power headroom for a physical uplink shared channel (PUSCH) that is transmitted in a first transmission period of a first band having a first subcarrier interval. The power headroom is computed on the basis of at least one second transmission interval of a second band having a second subcarrier interval which overlaps with the first transmission interval.

Abstract: Disclosed, in the present invention, are a method for transmitting, by a base station, a downlink signal in a wireless communication system supporting an unlicensed band, and a device for supporting the same. More particularly, in accordance with one embodiment of the present invention, when acknowledgment timing of each terminal (for example, an interval length from a time point of receiving downlink data to a time point of transmitting acknowledgment information for the downlink data) is set flexibly (or independently), a base station may determine a reference downlink resource for contention window size (CWS) adjustment by considering the acknowledgement timing and perform downlink signal transmission by adjusting CWS on the basis of the acknowledgment information received for the reference downlink resource.
