1. A method performed by a user equipment (UE) of a communication system, the method comprising:
receiving, from a base station, physical uplink control channel (PUCCH) configuration information including first information on a PUCCH format for repeated PUCCH transmissions, second information on a set of start symbols to be used in a slot, and third information on a set of number of symbols used in the slot;
receiving, from the base station, downlink data based on a downlink control channel (DCI) for scheduling the downlink data; and
repeatedly transmitting, to the base station, hybrid automatic repeat request acknowledgment (HARQ-ACK) information for the downlink data on a PUCCH based on the PUCCH configuration information,
wherein a start symbol in the slot for at least one PUCCH transmission is determined based on the second information and the number of symbols in the slot for the at least one PUCCH transmission is determined based on the third information.
