Abstract: A method of performing a channel access procedure (CAP) for a physical uplink shared channel (PUSCH) by a user equipment (UE) in a wireless communication system, is discussed. The method can include performing a CAP based on a first channel access priority class value; receiving, from a base station, downlink control information including (i) first information for scheduling the PUSCH and (ii) second information related to a second channel access priority class value; and based on the first channel access priority class value being same or larger than the second channel access priority class value, performing the CAP based on the first channel access priority class value, and transmitting the PUSCH based on the first information.

Abstract: According to an embodiment of the present invention a user equipment (UE) may receive, in a first search space set, first downlink control information (DCI) that schedules a first physical downlink control channel (PDSCH) based on a first transmission configuration index (TCI) value and receive, in a second search space set of the plurality of search space sets, second DCI that schedules a second PDSCH based on a second TCI value. The UE may determine that a transport block (TB) in the second PDSCH is re-transmission of a TB in the first PDSCH, based on that the first DCI and the second DCI indicates a same hybrid automatic repeat request (HARQ) process identifier (ID), and the first DCI and the second DCI indicates a same new data indicator (NDI) value, even if the first TCI value associated with the first PDSCH is different from the second TCI value associated with the second PDSCH.
