A resource indication method, performed by a network side device, comprising: transmitting first Downlink Control Information, DCI; wherein the first DCI is used for indicating Physical Uplink Control Channel, PUCCH, resource for transmitting Hybrid Automatic Repeat reQuest, HARQ,-Acknowledgement, ACK, information for at least two terminals; wherein Cyclic Redundancy Check, CRC, of the first DCI is scrambled by a first Radio Network Temporary Identifier, RNTI, wherein the first RNTI is a common parameter of the at least two terminals that receive the first DCI; characterized in that the method further comprises: configuring at least two sets of downlink configuration information for a terminal through high-layer signaling, wherein the downlink configuration information comprises: downlink Demodulation Reference Signal, DMRS, configuration information and/or Physical Downlink Shared Channel, PDSCH, configuration information; wherein the at least two sets of downlink configuration information comprise: downlink configuration information applicable to PDSCH scheduled by the first DCI, of which CRC is scrambled by the first RNTI; and downlink configuration information applicable to PDSCH scheduled by a second DCI, of which CRC is scrambled by an RNTI other than the first RNTI; wherein the first DCI comprises a first information field, the first information field comprises at least two PUCCH resource indicators, and each of the PUCCH resource indicators is used for indicating the PUCCH resource for a respective one of the terminals, wherein the method further comprises: configuring for the terminal a position of the PUCCH resource indicator of the terminal in the first information field through high-layer signaling. transmitting first Downlink Control Information, DCI;
