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: According to an embodiment of the present the UE can be scheduled to simultaneously receive one or more PDSCHs and one or more UE-group common PDSCHs at a same slot. When the simultaneously reception exceeds the UE's simultaneous reception capability, the UE may prioritizes a PDSCH for random access procedure over remaining PDSCHs, determine priorities of the remaining PDSCHs based on priority information in each DCI, and receive ‘M’ PDSCHs including the PDSCH for random access and ‘M−1’ PDSCHs selected from the remaining PDSCHs, where ‘M’ related to the UE's simultaneous reception capability.

Abstract: A method and device for transmitting/receiving a signal in a wireless communication system, according to one embodiment of the present invention, transmits a PUCCH including UCI. With respect to a resource for transmitting the PUCCH, the PUCCH is determined to be associated with a first interlace, among the first interlace and a second interlace, on the basis that: (i) the first interlace, and the second interlace having a higher index than that of the first interlace are configured by means of information on the PUCCH resource; and (ii) the number of physical resource blocks (PRBs) for transmitting the UCI is equal to or less than the number of PRBs of the first interlace.
