A resource indication method, comprising: determining, by a base station, a resource used by a terminal to send an uplink control signal; and sending, by the base station, indication information to the terminal, wherein the indication information is used to indicate a target parameter, and the target parameter comprises at least one of parameters used by the terminal to determine the resource, wherein the parameters used to determine the resource comprise a first parameter and a second parameter, and the target parameter comprises the first parameter or the second parameter, wherein the first parameter is used to determine a resource group comprising the resource and the second parameter is used to determine the resource in the resource group, or the first parameter is used to determine a basic resource index value of the resource and the second parameter is used to determine an offset resource index value of the resource, wherein the determining, by a base station, a resource used by a terminal to send an uplink control signal comprises: determining the first parameter based on the target parameter and the second parameter based on a downlink resource, the first parameter being included in the target parameter, or determining the second parameter based on the target parameter and the first parameter based on a downlink resource, the second parameter being included in the target parameter; and determining, by the base station based on the first parameter and the second parameter, the resource used by the terminal to send the uplink control signal. determining, by a base station, a resource used by a terminal to send an uplink control signal; and sending, by the base station, indication information to the terminal, wherein the indication information is used to indicate a target parameter, and the target parameter comprises at least one of parameters used by the terminal to determine the resource, wherein the parameters used to determine the resource comprise a first parameter and a second parameter, and the target parameter comprises the first parameter or the second parameter, wherein the first parameter is used to determine a resource group comprising the resource and the second parameter is used to determine the resource in the resource group, or the first parameter is used to determine a basic resource index value of the resource and the second parameter is used to determine an offset resource index value of the resource, wherein the determining, by a base station, a resource used by a terminal to send an uplink control signal comprises: determining the first parameter based on the target parameter and the second parameter based on a downlink resource, the first parameter being included in the target parameter, or determining the second parameter based on the target parameter and the first parameter based on a downlink resource, the second parameter being included in the target parameter; and determining, by the base station based on the first parameter and the second parameter, the resource used by the terminal to send the uplink control signal. determining the first parameter based on the target parameter and the second parameter based on a downlink resource, the first parameter being included in the target parameter, or determining the second parameter based on the target parameter and the first parameter based on a downlink resource, the second parameter being included in the target parameter; and determining, by the base station based on the first parameter and the second parameter, the resource used by the terminal to send the uplink control signal.
