    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). A method of a user equipment is provided. The method includes identifying a first bandwidth part for a cell and a second bandwidth part for the cell through radio resource control signaling; identifying a first control resource set on the first bandwidth part and a second control resource set on the second bandwidth part through the radio resource control signaling; and acquiring downlink control information for the second bandwidth part based on the first control resource set on the first bandwidth part being activated. A bandwidth part indicator, a frequency domain resource assignment, and a time domain resource assignment are included in the downlink control information.

    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 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 base station in a wireless communication system includes a transceiver configured to transmit and receive a signal; and a controller configured to transmit, to a terminal, a control message including first information configuring a physical uplink control channel (PUCCH) resource of a PUCCH format 2, second information associated with a demodulation reference signal (DMRS) for physical uplink shared channel (PUSCH) of a mapping type A, and third information associated with a DMRS for PUSCH of a mapping type B, identify the PUCCH resource based on the first information, and receive, from the terminal on the PUCCH resource, a DMRS for PUCCH format 2 based on the control message. A sequence of the DMRS for PUCCH format 2 is generated based on a scrambling identity (ID) included in the third information of the control message.
