Abstract: A communication scheme and a system of converging an IoT technology and a 5th generation (5G) communication system for supporting a higher data transfer rate beyond a 4th generation (4G) system are provided. The communication scheme includes intelligent services (e.g. smart home, smart building, smart city, smart car or connected car, health care, digital education, retail business, and security and safety-related services), based on a 5G communication technology and an IoT-related technology. A method performed by a terminal in a communication system is provided. The method includes receiving, from a base station, a semi-persistent scheduling (SPS) configuration including an SPS configuration index; identifying at least one physical downlink shared channel (PDSCH) corresponding to the SPS configuration; identifying a PDSCH with a lowest SPS configuration index in case that the at least one PDSCH corresponding to the SPS configuration is overlapped in time in a slot; determining a PDSCH for data transmission based on excluding a PDSCH that is overlapped with the PDSCH with the lowest SPS configuration index from the at least one PDSCH; and receiving, from the base station, data based on the determined PDSCH, wherein the at least one PDSCH is not overlapped with a symbol indicated as an uplink in the slot.

Abstract: Methods and apparatuses are provided in which first downlink control information (DCI) for scheduling a physical downlink shard channel (PDSCH) is transmitted to a terminal. Second information indicating one among preset first values is included in the DCI. The PDSCH associated with the DCI is transmitted to the terminal. Acknowledgement information associated with the PDSCH is received from the terminal based on a first transmission time interval (TTI) determined based on both a TTI associated with the PDSCH and a value associated with the second information. The preset first values are numbers of at least one TTI between the TTI associated with the PDSCH and a TTI for transmission of the acknowledgement information associated with the PDSCH.

Abstract: A method is provided for a user equipment (UE) to obtain slot format information. The method includes receiving, from a base station (BS), configuration information about a physical downlink control channel (PDCCH); detecting downlink control information (DCI), based on the configuration information; obtaining slot format indicator (SFI) information and information about a channel occupancy time (COT) in the DCI; and determining a slot or a symbol to which the SFI information is to be applied, based on the information about the COT.

Abstract: Methods and apparatuses in a wireless communication system is provided. Configuration information for defining a downlink assignment for a bandwidth part (BWP) is transmitted to a user equipment (UE) by higher layer signaling. At least one BWP is configured in a cell of the base station and the higher layer signaling is UE specific. An activated BWP is identified. Downlink control information (DCI) is transmitted on the activated BWP. Data is transmitted to the UE on the activated BWP according to the downlink assignment for the activated BWP. The downlink assignment is defined on the activated BWP, based on both the configuration information by the higher layer signaling and remaining information by the DCI.
