Abstract: The present disclosure relates to a method of monitoring, by a wireless device, a downlink channel or a downlink signal. The method may include a step of receiving configuration information on a power save signal. The power saving signal can be used to signal that the downlink channel or the downlink signal should be monitored later. The configuration information may contain configuration information on an opportunity to omit the power saving signal. The method may include a step of monitoring the downlink channel or the downlink signal without monitoring the energy saving signal during the opportunity to omit. The length and/or position of the opportunity of omission can be determined according to the configuration information of a discontinuous receive cycle (DRX).

Abstract: One disclosure of the present application provides a method for a narrowband (NB) wireless device to determine whether or not to transmit a scheduling request (SR). The method may comprise a step of determining whether or not to transmit an SR by using a resource for the transmission of a hybrid automatic retransmit request (HARQ) acknowledgement/negative acknowledgement (ACK/NACK) signal. The step of determination may be performed if one or more HARQ processes are run. The resource for the HARQ ACK/NACK signal may include a narrowband physical uplink shared channel (NPUSCH).

Abstract: A terminal performing initial cell access, according to an embodiment of the present disclosure, receives a PBCH signal through an SSB, receives SIB1-scheduling information for a first CORESET on the basis of the PBCH signal, and receives an SIB1 through a PDSCH, wherein the terminal is a second type terminal with reduced capability to support a maximum bandwidth smaller than that of a first type terminal among different types of terminals supported in a 3GPP-based wireless communication system, and even though the PBCH signal received by the terminal is set to be the same as a PBCH signal received by the first type terminal, the SIB1 received by the terminal may include a second type SIB1 different from a first type SIB1 that the first type terminal receives.
