    Abstract: Disclosed are a method for performing uplink transmission or reception in a wireless communication system and a device therefor. Specifically, a method for performing uplink transmission by a terminal in a wireless communication system may comprise the steps of: receiving, from a base station, a configuration relating to a beam association between a resource in a first frequency band and a resource in a second frequency band; allocating, by the base station, the resource in the first frequency band to the terminal, wherein the first frequency band does not overlap with the second frequency band; switching the first frequency band to the second frequency band; allocating, by the base station, the resource in the second frequency band to the terminal; and on the basis of the configuration relating to the beam association, performing the uplink transmission on the resource in the second frequency band.

    Abstract: This specification provides a method for transmitting, by a user equipment (UE), a CSI (Channel State Information) report in a wireless communication system. More specifically, the method includes: receiving, from a base station, downlink control information (DCI) including information for triggering the CSI report; computing CSI based on the number of symbols related to a time for computing the CSI; and transmitting the CSI report to the base station, in which the number of symbols related to the time for computing the CSI is defined based on information for the number of antenna ports, information for a CSI-RS resource, information for a bandwidth granularity, and information for a CSI codebook type.

    Abstract: A method for receiving a downlink signal according to a Demodulation Reference Signal (DMRS)-based transmission scheme, performed by a mobile terminal, in a wireless communication system is disclosed. The method includes receiving indication information indicating whether rate matching or timewise Resource Element (RE) pairing is allowed for REs that do not constitute frequency-wise RE pairs for Space Frequency Block Coding (SFBC) on symbols to which DMRSs are mapped in a Resource Block (RB) for a DL data channel, and decoding the downlink data channel, on assumption that the REs that do not constitute frequency-wise RE pairs for SFBC are rate-matched, or constitute time-wise RE pairs to which transmission data is mapped, according to the indication information.
