Abstract: A terminal according to one embodiment of the present invention may: receive first DCI including a first HARQ process ID field and a first NDI field on the basis of a first RNTI for a terminal group; receive a first PDSCH scheduled by the first DCI; receive second DCI on the basis of a second RNTI dedicated to the terminal in a state in which a data block of the first PDSCH has not been successfully decoded; and receive a second PDSCH scheduled by the second DCI, wherein a second HARQ process ID field included in the second DCI indicates the same HARQ process as the first HARQ process ID field included in the first DCI; and, on the basis of the fact that a value of a second NDI field included in the second DCI is the same as the value of the first NDI field included in the first DCI, a data block of the second PDSCH may be decoded on the assumption that the second PDSCH includes retransmission for the data block of the first PDSCH that has not been successfully decoded, notwithstanding that the second RNTI is different from the first RNTI.

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).
