Abstract: A user equipment/base station receives/transmits resource allocation for a PUSCH; determines a plurality of radio resources on the basis of the resource allocation; and repeatedly transmits/receives the PUSCH on the basis of the plurality of radio resources. The repeated transmission/reception of the PUSCH may comprise: applying PUSCH mapping type B to each of the plurality of radio resources; and transmitting a demodulation reference signal (DMRS) for the PUSCH, on the basis of the plurality of radio resources and the PUSCH mapping type B.

Abstract: Systems and techniques related to allocating resources for a user equipment (UE) via downlink control information (DCI) in a wireless communication system. Specifically, a UE receives, from a base station, a radio resource control (RRC) message including list information associated with a plurality of time-domain resource allocation (TDRA) tables, and receives, from the base station, a DCI in order to be allocated a resource on a time domain. Here, the resource in the time-domain is allocated according to one TDRA table among the plurality of TDRA tables, based on the DCI and the one TDRA table is selected among the plurality of TDRA tables, based on a configuration of the DCI or a field included in the DCI.

Abstract: A terminal according to an embodiment of the present invention can: encode a plurality of UCIs comprising a first UCI and a second UCI; perform resource mapping on the encoded bits of the plurality of UCIs on a single physical uplink channel; and perform uplink transmission on the basis of the resource mapping. Even when the first UCI and the second UCI have different priorities, the terminal can separately encode the first UCI and the second UCI on the basis that the first UCI and the second UCI are configured to be multiplexed on the single physical uplink channel, and perform the resource mapping on the second UCI having the lower priority on the basis of the resource mapping of the first UCI having the higher priority.

Abstract: A user equipment (UE) may determine a first transmission time for a first hybrid automatic repeat request acknowledgement (HARQ-ACK) for a first downlink channel associated with a first HARQ process; and receive a second downlink channel associated with the first HARQ process. Receiving the second downlink channel for the first HARQ process may include: receiving the second downlink channel after the first transmission time based on the first HARQ-ACK being not subject to HARQ deferral; and receiving the second downlink channel after a second transmission time based on the first HARQ-ACK being subject to the HARQ deferral and the first transmission time being determined by the HARQ deferral from the second transmission time earlier than the first transmission time.

Abstract: Disclosed are a method for transmitting and receiving a radio signal in a wireless communication system and an apparatus therefor. Particularly, a method for performing, by a terminal, channel state information (CSI) reporting in a wireless communication system comprises the steps of: receiving, from a base station, bandwidth part (BWP) configuration information on a BWP for uplink and/or downlink transmission; receiving, from the base station, reporting configuration information including a reporting configuration for the CSI reporting; and performing the CSI reporting on the basis of the BWP configuration information and the reporting configuration information, wherein the reporting configuration is associated with the BWP, and whether or not the reporting configuration is activated may be determined on the basis of whether or not the BWP is activated.

Abstract: Systems and techniques for transmitting a physical uplink control channel (PUCCH) carrying a scheduling request (SR) in a wireless communication system. In some implementations, a method performed by a terminal includes the steps of: receiving, from a base station, a first message related to configuration of an uplink (UL) resource; receiving, from the base station, a second message related to resource configuration of a PUCCH carrying the SR; determining a resource for transmission of the PUCCH carrying the SR; and transmitting, to the base station, the PUCCH carrying the SR on the determined resource.

Abstract: One disclosure of the present specification provides a method for receiving, by a user equipment (UE), a downlink control channel. The method may comprise a step of receiving a downlink control channel. The downlink control channel may be scrambled by a scrambling sequence. The scrambling sequence may be initialized by using a predetermined identifier which is different from an identifier (ID) of the UE.
