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: The present invention relates to a method for transmitting hybrid automatic repeat request acknowledgement (HARQ-ACK) information by a half duplex (HD)-frequency division duplex (FDD) method in a wireless communication system supporting multiple transport block scheduling, and an apparatus therefor. The method comprises: receiving downlink control information (DCI) scheduling N transport blocks; repeatedly receiving the N transport blocks on the basis of the DCI by R times without interleaving; and starting transmission of hybrid automatic repeat request acknowledgement (HARQ-ACK) information of the N transport blocks after a particular number of subframes from a time point at which the reception of the N transport blocks is complete, wherein the particular number is determined to be the larger value among 1 and (3−(N−1)*R).

Abstract: A method for controlling, by a user equipment (UE), a transmit power in a narrowband (NB) wireless communication system is disclosed. The method includes receiving, from a base station, a preconfigured uplink (UL) resource (PUR) configuration, transmitting, to the base station, uplink data on the PUR, and receiving, from the base station, feedback information for the uplink data. A transmit power of the uplink data is controlled based on a number of receptions of the feedback information.
