A method of a user equipment (UE) in a wireless communication system, includes receiving a downlink channel from a base station; identifying a reference slot associated with physical uplink control channel (PUCCH) transmission, wherein the identifying of the reference slot comprises, in case that a higher layer parameter configuring a sub-slot for a PUCCH is received, identifying that the reference slot is the last uplink slot for PUCCH transmission that overlaps with the downlink channel, and in case that the higher layer parameter is not received, identifying that the reference slot is the last uplink slot for PUCCH transmission that overlaps with a downlink slot for the downlink channel reception; and transmitting, to the base station, a PUCCH including hybrid automatic repeat request acknowledgment (HARQ-ACK) information corresponding to the downlink channel based on the reference slot.

Method and apparatus for transmitting and receiving data based on a higher layer parameter associated with a PUCCH in wireless communication system

The disclosure relates to a 5th generation (5G) or 6th generation (6G) communication system for supporting a higher data transmission rate. A method performed by a terminal is provided. The method performed by a terminal includes receiving, from a base station, DCI scheduling a plurality of PDSCHs on a PDCCH, wherein the DCI includes information on a TDRA and information on a TCI state, identifying symbol offsets between the PDCCH and the plurality of PDSCHs based on the TDRA, in case that a first symbol offset between the PDCCH and a first PDSCH is less than a threshold, receiving, from the base station, the first PDSCH based on a default TCI state, and in case that a second symbol offset between the PDCCH and a second PDSCH is equal to or greater than the threshold, receiving, from the base station, the second PDSCH based on the TCI state.

Method and apparatus for configuring beam in wireless communication system

The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. Provided is a method performed by a user equipment (UE), the method including receiving downlink control information (DCI) scheduling a plurality of physical downlink shared channels (PDSCHs); identifying a value of a hybrid automatic repeat and request (HARQ) feedback timing indicator included in the received DCI; and performing the HARQ feedback transmission, based on the identified value of the HARQ feedback timing indicator, wherein in case that the value is identified as a non-numerical value, HARQ feedback information for the plurality of PDSCHs is not transmitted based on the DCI and the HARQ feedback information for the plurality of PDSCHs is transmitted after an other DCI including a numerical value of the HARQ feedback timing indicator is received.
