Abstract: Provided are a method and apparatus for transmitting and receiving a signal in a wireless communication system, according to an embodiment of the present disclosure, the method comprising the steps of: receiving information indicating a demodulation-reference signal (DM-RS) port related to transmission of a physical uplink shared channel (PUSCH); and transmitting the PUSCH and a DM-RS on the basis of the information. Provided are a method and apparatus for transmitting and receiving a signal in a wireless communication system, according to another embodiment of the present disclosure, the method comprising the steps of: receiving information indicating a demodulation-reference signal (DM-RS) port related to reception of a physical downlink shared channel (PDSCH); and receiving the PDSCH and a DM-RS on the basis of the information. On the basis of a determination about a frequency domain orthogonal cover code (OCC) being not applied to the DM-RS port indicated by the information, the DM-RS may be transmitted after a change operation for the DM-RS port.

Abstract: A method and an apparatus for transmitting and receiving a physical downlink control channel (PDCCH) in a wireless communication system are disclosed. A method of receiving a physical downlink control channel (PDCCH) according to an aspect of the present disclosure may include: receiving, from a base station, a synchronization signal/physical broadcast channel (SS/PBCH) block including a primary synchronization signal (PSS), a secondary synchronization signal (SSS) and a PBCH; and receiving, from the base station, the PDCCH on a PDCCH monitoring occasion determined based on a master information block (MIB) in the SS/PBCH block.

Abstract: Provided are a method and apparatus for determining a transport block size (TBS) when transmitting a transport block through a PUSCH by applying transport block processing over multiple slots (TBoMS) in a wireless communication system. The UE determines the TBS based on the number of resource elements (NRE) allocated for the PUSCH, in this case, considers the number of slots for the TBoMS.

Abstract: A UE performs PDCCH monitoring for at least one serving cell by switching a search space set of a first SSSG to a search space of a second SSSG at a search space set group (SSSG) switching time. When PDCCH monitoring is performed in a unit of a slot-group for the at least one serving cell, the UE determines the SSSG switching time based on a largest Xs value among Xs values for the at least one serving cell.

Abstract: Disclosed herein are a method and device for monitoring a signal in a wireless communication system, including PDCCH monitoring based on a configuration related to a search space. The maximum valid value of the slot duration for the search space is limited to a value obtained by subtracting L from the periodicity, where L is related to the size of slot-groups configured for the search space.

Abstract: A method and an apparatus for monitoring a signal in a wireless communication system, disclosed in the present disclosure, perform PDCCH monitoring based on a configuration regarding a search space set. The PDCCH monitoring may be performed in units of slot-groups and performed only in a certain number of consecutive slots in a period given by a periodicity and an offset. When a duration related parameter indicating the number of consecutive slots in which the search space may exist is absent in the configuration, the certain number is determined based on the size of a slot-group configured for the search space set.
