4. A radio communication method for a terminal, comprising:
receiving a configuration for a physical uplink control channel (PUCCH) corresponding to a multicast physical downlink shared channel (PDSCH), downlink control information (DCI) for scheduling the PDSCH, and the PDSCH, wherein the configuration is transmitted using radio resource control (RRC) signaling; and
determining a PUCCH resource for hybrid automatic repeat request acknowledgement (HARQ-ACK) corresponding to the PDSCH, based on the configuration, a PUCCH resource indicator field included in the DCI, and a control channel element (CCE) index of a physical downlink control channel (PDCCH) that carries the DCI,
wherein the DCI is common to a plurality of terminals, and
wherein a PUCCH format for the PUCCH resource is a PUCCH format without a demodulation reference signal.
