Abstract: The present disclosure relates to a communication technique for combining IoT technology and a 5G communication system for supporting a higher data transmission rate than a 4G system, and a system therefor. The present disclosure may be applied to intelligent services (e.g., smart home, smart building, smart city, smart car or connected car, healthcare, digital education, retail, security- and safety-related services, etc.) on the basis of 5G communication technology and IoT-related technology. According to an embodiment of the present disclosure, a method by a base station in a wireless communication system comprises the steps of: transmitting, to a terminal, downlink control information comprising resource allocation information for a virtual domain and resource allocation information for a physical downlink shared channel (PDSCH); multiplexing the PDSCH in a virtual domain resource on the basis of the resource allocation information for the virtual domain; and performing discrete fourier transform (DFT) precoding for the multiplexed PDSCH.

Abstract: Provided are a method and apparatus for transmitting data in a wireless communication system. The method, performed by a transmission apparatus, of transmitting data includes performing π/2-binary phase shift keying (BPSK) modulation on M symbols, performing a discrete Fourier transform (DFT) on the M symbols on which the π/2-BPSK modulation has been performed, performing an inverse fast Fourier transform (IFFT) on M/2 symbols among the M symbols on which the DFT has been performed, and transmitting, to a reception apparatus, the M/2 symbols on which the IFFT has been performed, wherein a constellation of the M symbols on which the π/2-BPSK modulation has been performed may have only real components or imaginary components.

Abstract: The disclosure relates to a pre-5G or 5G communication system to be provided for supporting higher data rates beyond a 4G communication system, such as LTE. A method includes receiving, by a UE, PDCCH information from a network entity, where the PDCCH information includes DCI and PDSCH information, and determining, by the UE, the default beam behavior based on a CORESET with a lowest ID among first and second CORESETs, in response to determining that a TCI state is not present in the DCI and the scheduling offset between reception of all transmission occasions of DL DCI and the corresponding PDSCH information of the serving cell is greater than or equal to the threshold.

Abstract: Methods and apparatuses in a wireless communication system are provided. Capability information regarding the terminal is transmitted. The capability information is associated with an X division duplexing (XDD) system. Resource configuration information is received based on the resource configuration information. A resource on which uplink control information (UCI) is to be transmitted is determined. The UCI is transmitted on the determined resource. The XDD system configures an uplink resource and a downlink resource in a same slot in different frequency resources.
