Method and apparatus for transmitting and receiving uplink control channel in communication system
An operation method of a terminal in a communication system may comprise receiving a downlink data channel from a base station in a slot # n or a slot # (n−l); receiving a slot format indicator (SFI) indicating a format of a slot # (n+k) in which an uplink control information (UCI) is to be transmitted, from the base station in the slot # n; and transmitting the UCI including a hybrid automatic repeat request (HARQ) response for the downlink data channel to the base station in the slot # (n+k). Here, each of n and k may be an integer equal to or greater than 0, and l may be an integer equal to or greater than 1.
1. An operation method of a user equipment (UE) in a communication system, the operation method comprising:
receiving configuration information indicating a slot format through a higher layer signaling;
receiving a repetition number (N) of physical uplink control channel (PUCCH) transmission through the higher layer signaling;
identifying a plurality of slots including non-downlink (DL) symbols based on the slot format; and
transmitting a PUCCH N times using N slots among the plurality of slots.
2. The operation method of claim 1 , wherein, when one slot among N consecutive slots is not used for the PUCCH transmission according to the configuration information, an available slot which corresponds to the configuration information after the N consecutive slots is used for the PUCCH transmission.
3. The operation method of claim 1 , wherein the PUCCH is transmitted based on frequency hopping.
