    Abstract: The disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. A method of a terminal in a wireless communication system is provided. The method includes receiving, from a first cell of a base station, cross carrier scheduling configuration including information indicating that a carrier indicator field (CIF) is included in downlink control information (DCI); receiving, from the first cell of the base station, the DCI for scheduling a physical downlink shared channel (PDSCH), the DCI including the CIF; if the CIF indicates that a resource assignment of the PDSCH is for the first cell, identifying whether a first offset value between a reception of the DCI and the PDSCH is less than a threshold; and in case that the first offset value is less than the threshold and the terminal supports default beam selection for the PDSCH, receiving, from the first cell of the base station, data on the PDSCH based on quasi co-located (QCL) parameters for a control resource set (CORESET) associated with a search space with a lowest CORESET identifier (ID) within an active bandwidth part (BWP) of the first cell in a latest slot monitored by the terminal.

    Abstract: The disclosure relates to converging a 5G communication system for supporting higher data rates beyond a 4G system with a technology for IoT, and may be applied to intelligent services based on the 5G communication technology and IoT-related technology. The disclosure provides a method performed by a UE in a communication system. The method includes receiving, via higher layer signaling, a configuration of PUSCH repetition; receiving, on a PDCCH, DCI including a TDRA field; identifying, based on the configuration and the TDRA field, a plurality of time resources for the PUSCH repetition; identifying whether predefined conditions are satisfied; and transmitting, on the plurality of time resources, the PUSCH repetition while maintaining power consistency for the PUSCH repetition in case that the predefined conditions are satisfied. The predefined conditions include a first predefined condition corresponding to frequency hopping being not configured for the PUSCH repetition.

    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.
