Abstract: Provided are a method and device for monitoring a downlink control channel of a terminal in a wireless communication system. The terminal receives configuration information which informs of the position of an SSB or configuration information which informs of the position of an LTE CRS, and receives configuration information which informs of a monitoring occasion for detecting a wake up signal (WUS). If first PDCCH monitoring for detecting the wake up signal is not required since a resource of the monitoring occasion overlaps with a resource of the SSB and/or a resource of the LTE CRS, the terminal performs second PDCCH monitoring in a next discontinuous reception (DRX)-on duration.

Abstract: Proposed in the present specification is a method for transmitting and receiving urgent information in a wireless communication system supporting machine type communication, and a device for same. Specifically, a method performed by a terminal may include the steps of: receiving information including a Reference Signal Received Power (RSRP) threshold value from a base station; determining a Coverage Enhancement (CE) mode on the basis of the RSRP threshold value and an RSRP measurement value; determining a Physical Random Access Channel (PRACH) resource on the basis of the CE mode; and transmitting a PRACH preamble to the base station on the basis of the PRACH resource.

Abstract: A transmission device may perform listen-before-talk (LBT) with regard to an unlicensed band. The transmission device may determine M LBT sub-bands which are in an idle state, on the basis of the performing of the LBT for the unlicensed band. The transmission device may perform N repetitive transmissions of a transport block (TB) over the M LBT sub-bands. The N repetitive transmissions of the TB may include performing M repetitive transmissions over the M LBT sub-bands, respectively.

Abstract: Provided are a discontinuous reception (DRX) operation method of a terminal in a wireless communication system and an apparatus applying the method. The method comprises the steps of: receiving, from a base station, first configuration information which indicates a monitoring occasion for detecting first DCI comprising information that indicates whether the terminal has woken up; receiving, from the base station, second configuration information which indicates an operation to be applied to the terminal when the first DCI is not detected; monitoring a first PDCCH in order to detect the first DCI in the monitoring occasion; and when the first DCI fails to be detected in the monitoring occasion, monitoring a second PDCCH for detecting not the first DCI but second DCI in a next DRX-on duration on the basis of the second configuration information.

Abstract: Provided are a method by which a terminal monitors a downlink control channel in a wireless communication system, and a device. The method receives a configuration message that notifies of a monitoring occasion for detecting a wake up signal and, if first control channel monitoring for detecting the wake up signal is not required in the at least one monitoring occasion, monitors a second control channel in the next DRX-on section.

Abstract: A method and a device for monitoring a downlink control channel of a terminal are provided. The method comprises: receiving a first setting message that indicates the direction of resources of a slot and a second setting message that indicates a monitoring occasion for detecting a wake up signal (WUS); and monitoring a second downlink control channel in the next DRX-on section, if a resource constituting the monitoring occasion overlaps a resource designated as an uplink by the first setting message so that first downlink control channel monitoring for detecting the wake up signal is not required.

Abstract: The present specification provides an error detection method performed by a terminal in a wireless communication system, the method comprising: determining whether a minimum slot offset from a base station has been detected, wherein the minimum slot offset is a slot offset associated with an expectation that the terminal should receive a physical downlink shared channel (PDSCH) on the basis of at least one slot offset having a value equal to or greater than that of the minimum slot offset; detecting an error relating to detection of the minimum slot offset; and performing a fallback operation on the basis of the error detection.
