wherein at least two PUCCH formats of the plural PUCCH formats are classified based on a number of symbols, which are used for a PUCCH format, in a single slot,
wherein the at least two PUCCH formats includes a first PUCCH format using one or two symbols and a second PUCCH format using four or more symbols,
wherein for at least one PUCCH format, at least one PUCCH resource is configured, and
wherein the at least one PUCCH resource includes one or more physical resource blocks (PRBs); and
receiving a PUCCH including uplink control information (UCI) using at least one PUCCH format, based on the PUCCH resource information,
wherein based on a situation where both the first PUCCH format using one or two symbols and the second PUCCH format using four or more symbols are configured to be transmitted in a slot, only the second PUCCH format is used, in the slot, for transmitting the PUCCH based on a type of the UCI.
10. The method according to claim 9 , wherein the PUCCH resource information includes PRB allocation information, and
wherein the transmission type information in the higher layer signaling includes information about whether frequency hopping is performed.
11. The method according to claim 9 ,
wherein the plural PUCCH formats are classified based on whether one or two symbols are to be used or whether four or more symbols are to be used.
12. The method according to claim 9 ,
wherein the number of symbols is not less than one (1) in the single slot.
13. The method according to claim 9 , wherein the at least two PUCCH formats are classified based on a payload size of the UCI.
14. A user equipment (UE) for transmitting uplink (UL) control information, the user equipment comprising:
