Abstract: This specification provides a method of transmitting an uplink signal based on a codebook in a wireless communication system. More specifically, the method performed by a UE includes receiving, from a base station, downlink control information (DCI) including a first transmit precoding matrix indicator (TPMI), determining a codebook subset related to the transmission of the uplink signal based on the first TPMI, and transmitting, to the base station, the uplink signal based on the determined codebook subset. Accordingly, there is an advantage in that flexibility in the transmission antenna design of a UE can be increased because the degree of freedom of antenna port selection is increased.

Abstract: A method for transmitting and receiving channel state information (CSI) in a wireless communication system, and an apparatus therefor are disclosed. Specifically, a method for a terminal transmitting CSI in a wireless communication system supporting multi-user superposition transmission (MUST) may comprise the steps of: reporting to a base station a first precoding matrix indicator (PMI) indicating a precoding matrix that is the most preferred by the terminal, and a first channel quality indicator (CQI) that is calculated assuming use of the first PMI; and reporting to the base station a second PMI indicating a precoding matrix that is secondly preferred by the terminal, and a second CQI that is calculated assuming use of the second PMI.

Abstract: Provided are an operating method for an IAB node including a DU and an MT in a wireless communication system, and a device. The method receives first resource direction information about the DU and second resource direction information about the MT, wherein each of the first and second resource direction information indicates the direction of each resource as being downlink, uplink or flexible. The IAB node determines, for a certain resource from among the resources, whether the DU and the MT can operate at the same time on the basis of the direction indicated by the first resource direction information and the direction indicated by the second resource direction information.
