Abstract: A method for transmitting an SRS by a terminal may comprise the steps of: receiving, from a base station, information on a first bandwidth part (BWP) and a second BWP set for SRS transmission of the terminal; and when a frequency starting position for SRS transmission in the second BWP having a lower priority than the first BWP overlaps the first BWP, transmitting the SRS to the base station at an SRS bandwidth position different from an SRS bandwidth position associated with the frequency starting position for the SRS transmission. The UE is capable of communicating with at least one of another UE, a UE related to an autonomous driving vehicle, a base station or a network.

Abstract: A method for transmitting an SRS by a terminal may comprise the steps of: receiving, from a base station, one of an SRS resource indicator (SRI), a CSI-RS resource indicator (CRI), a synchronization signal block (SSB) identifier, and an uplink transmission configuration indicator (TCI); on the basis of whether the received indicator/identifier includes an indication that the corresponding indicator/identifier is commonly used for an SRS resource group or an indication that the corresponding indicator/identifier is used for a first SRS resource of the SRS resource group, determining whether to use the same transmission beam or use different transmission beams to transmit an SRS in the SRS resource group; on the basis of the determination, determining a transmission beam for the terminal, indicated by the received indicator/identifier; and transmitting the SRS in the first SRS resource on the basis of the transmission beam for the terminal, wherein the SRS resource group includes the first SRS resource and a second SRS resource. The UE is capable of communicating with at least one of another UE, a UE related to an autonomous driving vehicle, a base station or a network.

Abstract: A method for generating an SRS sequence by a terminal may comprise the steps of: calculating a first root value for generation of an SRS sequence of a first block among concatenated blocks configured for transmission of an SRS, using a terminal-specific SRS identifier; calculating a second root value for generation of an SRS sequence of a second block on the basis of the calculated first root value and a root offset value; and generating an SRS sequence for transmission of an SRS on the concatenated blocks by applying the first root value to the first block and applying the second root value to the second block.

Abstract: A method and device for receiving downlink data in a wireless communication system are discussed. The method performed by a terminal includes receiving, from a base station, first downlink control information through a physical downlink control channel (PDCCH) or a short PDCCH (sPDCCH), wherein the first downlink control information schedules a plurality of short physical downlink shared channel (sPDSCH) regions based on a first transmission time interval (TTI)-based radio frame structure, and each of the plurality of the sPDSCH regions is included in a different plurality of short subframes based on the first TTI-based radio frame structure, respectively; and receiving, from the base station, first downlink data in the plurality of the sPDSCH regions based on the first downlink control information, wherein the first TTI-based radio frame structure has a shorter interval than a second TTI-based radio frame structure for the PDSCH region in which second downlink data is transmitted.

Abstract: A method for transmitting a multiplexed uplink control channel and localized sounding reference symbol (localized SRS) by a terminal comprises a step of dividing the uplink control channel into a plurality of uplink control channel sub-blocks in a frequency domain and then transmitting the divided uplink control channel, when a frequency bandwidth of the localized SRS is smaller than or equal to a coherent bandwidth, wherein the divided uplink control channel sub-blocks may be frequency-division-multiplexed together with at least one localized SRS and then transmitted in one symbol.
