Abstract: A method, performed by a base station (BS), of indicating a channel occupancy time of an unlicensed band is provided and includes transmitting physical downlink control channel (PDCCH) configuration information to a user equipment (UE), performing a channel access procedure to occupy a channel of the unlicensed band, and transmitting slot format indicator information about at least one slot within a channel occupancy time occupied by performing the channel access procedure, based on the PDCCH configuration information, wherein the slot format indicator information is determined based on at least one of a maximum channel occupancy time of the BS or the channel occupancy time occupied by performing the channel access procedure.

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: A method performed by a terminal in a wireless communication system includes: receiving at least one downlink control information (DCI) from a base station; determining a physical uplink control channel (PUCCH) resource based on the at least one DCI; and transmitting a PUCCH including hybrid automatic repeat request acknowledgement (HARQ-ACK) information to the base station based on the determined PUCCH resource, wherein the determining of the PUCCH resource comprises: in case that a physical downlink shared channel (PDSCH)-to-HARQ feedback timing indicator field is present in the at least one DCI, determining the PUCCH resource based on information in the PDSCH-to-HARQ feedback timing indicator field in the at least one DCI; and in case that the PDSCH-to-HARQ feedback timing indicator field is not present in the at least one DCI, determining the PUCCH resource based on an radio resource control (RRC) signaling received from the base station.

Abstract: The disclosure relates to a communication technique for convergence between a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system and a technology for Internet of Things (IoT), and a system thereof. The disclosure may be applied to intelligent services (for example, smart homes, smart buildings, smart cities, smart cars or connected cars, health care, digital education, retail businesses, security and safety related services, etc.) based on the 5G communication technology and the IoT-related technology. Disclosed are a method and an apparatus for determining a time domain resource area allocation. A method of a terminal includes receiving, from a base station, downlink control information (DCI) including information indicating a channel occupancy (CO) duration of the base station; identifying a resource associated with a configured grant for an uplink signal within the CO duration; identifying a configuration for a symbol of the resource, in case that a slot format indicator (SFI) for the resource is not provided in the DCI; and transmitting, to the base station, the uplink signal in the resource based on the identified configuration.

Abstract: The present disclosure relates to a communication technique for converging a 5G communication system for supporting a higher data rate beyond a 4G system with an IoT technology, and a system therefor. The present disclosure can be applied to intelligent services (for example, smart home, smart building, smart city, smart car or connected car, healthcare, digital education, retail, security and safety-related service, and the like) on the basis of a 5G communication technology and an IoT-related technology. The present invention relates to a method for transmitting and receiving data, and a method for receiving data by a terminal according to the present invention comprises: receiving, from a base station, a random sequence generation parameter for generating a random sequence including a random variable in a first band; generating the random sequence using the received parameter; and performing decoding on the basis of the random variable included in the random sequence in a second band.
