13. A base station in a wireless communication system, the base station comprising:
a transceiver; and
a controller configured to:
transmit, via the transceiver, system information for a physical uplink control channel (PUCCH) configuration including first information associated with a PUCCH resource set,
transmit, via the transceiver, downlink control information (DCI) for scheduling a physical downlink shared channel (PDSCH),
transmit, via the transceiver, downlink data on the PDSCH, according to the DCI, and
receive, via the transceiver, feedback information for the PDSCH on a PUCCH using a PUCCH format 0 or a PUCCH format 1, according to the PUCCH configuration,
wherein in case that the system information includes second information indicating a number of resource blocks (RBs) used per PUCCH resource for at least one of the PUCCH format 0 or the PUCCH format 1, the PUCCH is received based on the number of RBs indicated by the second information, and
wherein a lowest physical resource block (PRB) for the PUCCH is determined based RBBWPoffset and └rPUCCH/NCS┘·NRB, where:
RBBWPoffset is a PRB offset associated with a bandwidth part (BWP),
rPUCCH is an index associated with a PUCCH resource,
NCS is a total number of initial cyclic shift indexes in a set of initial cyclic shift indexes, and
NRB is the number of RBs.
