Abstract: A base station and a user equipment may determine whether to determine a start symbol value representing a start symbol of a physical downlink shared channel (PDSCH) on the basis of a reference point which is different from the start of a slot allocated for the PDSCH of a cell and is based on the subcarrier spacing of the cell and the subcarrier spacing of a scheduling cell for the cell. The base station/user equipment may transmit/receive, through the scheduling cell, the DCI including symbol information on the start symbol value for the PDSCH on the basis of the determination.

Abstract: A method by which a terminal transmits data in an unlicensed band, and an apparatus using the method are provided. The method comprises: transmitting data to a base station through a physical uplink shared channel (PUSCH) in the unlicensed band; and receiving, from the base station, acknowledgement/negative acknowledgement (ACK/NACK) information about the data in the unlicensed band, wherein the terminal receives, from the base station, timeline information notifying of a time relationship between the PUSCH transmission time point and the ACK/NACK information reception time point.

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.
