    Abstract: Provided are a method for applying precoding to an uplink data channel and a device for same. Specifically, the method performed by a terminal in a wireless communication system comprises the steps of: receiving configuration information about repeated transmission of an uplink data channel; confirming a plurality of precoders for the repeated transmission of the uplink data channel; and repeatedly transmitting the uplink data channel to a base station on the basis of the configuration information and the plurality of precoders, wherein a first precoder among the plurality of precoders may be applied to a first uplink data channel, and a second precoder may be applied to an uplink data channel determined on the basis of at least one of the times of transmission of the repeated transmissions of the uplink data channel or a period associated with the application of the second precoder.

    Abstract: The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. Disclosed is a 5G or pre-5G communication system provided to support a higher data transmission rate than a 4G communication system such as LTE. A PDSCH scheduling method in a wireless communication system includes interpreting scheduling information with reference to information associated with an uplink subband, when a UE receives a PDSCH from a base station, by interpreting the size of a scheduled PRB and a bandwidth part size which are appropriate for full-duplex communication. A method of determining a PRG grid and a PRB bundling size which are appropriate for full-duplex communication when a UE receives a PDSCH from a base station includes receiving, from a BS, subband frequency information related to 95frequency domain resource allocation for an UL subband, receiving, from the BS, DC related to frequency domain resource allocation for a PDSCH, identifying a PRG including at least one PRB for the PDSCH based on the subband frequency information and the DCI, and receiving, from the BS, the PDSCH based on the PRG.

    Abstract: The present disclosure relates to a pre-5th generation (5G) or 5G communication system to be provided for supporting higher data rates beyond 4th generation (4G) communication system such as long term evolution (LTE). Embodiments herein provide a method for beam behavior of CSI-RS for FeMIMO. The method performed by a UE includes sending UE capability information comprising a beamSwitchTiming to at least one B S. The beamSwitchTiming indicates a minimum number of OFDM symbols between DCI triggering of aperiodic CSI-RS and aperiodic CSI-RS transmission. Further, the method includes receiving a PDCCH DCI for reception of the aperiodic CSI-RS from the at least one BS. Further, the method includes determining a default beam rule for reception of the aperiodic CSI-RS triggered by the DCI. Further, the method includes receiving the aperiodic CSI-RS from the at least one BS. Furthermore, the method includes processing the aperiodic CSI-RS by applying the default beam rule.

    Abstract: The present disclosure relates to a 5G or 6G communication system for supporting data transmission rates higher than that of a 4G communication system such as LTE. Disclosed are a method and an apparatus for indicating a frequency resource or a format of the resource in a wireless communication system using a dual connection scheme. The method and the apparatus of the present disclosure semi-statically or dynamically change: a method for classifying frequency resources as resource block sets or resource group units and configuring at least one from among uplink, downlink, and flexible frequency resource formats for a resource group; and the configured frequency resource format, and thus the frequency resources for uplink/downlink transmission and reception can be effectively used.
