1. A method for transmitting a first physical uplink control channel (PUCCH) with first hybrid automatic repeat request acknowledgement (HARQ-ACK) information bits, the method comprising:
receiving information for a set of PUCCH resources, wherein:
the information for the set of PUCCH resources is included in a first configuration for PUCCH transmissions that are associated only with receptions of multicast physical downlink shared channels (PDSCHs), and
the information for the set of PUCCH resources is included in a second configuration for PUCCH transmissions that are also associated with receptions of unicast PDSCHs when the first configuration is not provided;
determining:
values for the first HARQ-ACK information bits, wherein the first HARQ-ACK information bits are in response to receptions of the multicast PDSCHs, and
a PUCCH resource from the set of PUCCH resources according to a combination of positive acknowledgement values and negative acknowledgement values for the first HARQ-ACK information bits; and
transmitting the first PUCCH using the PUCCH resource.
