In 204, the network-side device receives the SR used to schedule the cached data, on the PUCCH resource determined by the reference information of the second parameter, the second parameter being a parameter associated with the PUCCH resource used to transmit the SR.
In 205, the network-side device queries the preset mapping relationship between the information of the first parameter and the information of the second parameter of the PUCCH resource to acquire the reference information, corresponding to the reference information of the second parameter, of the first parameter, the first parameter being a parameter associated with the cached data to be transmitted of the terminal.
In 206, the network-side device sends a resource scheduling instruction for the licensed resource used to transmit the cached data, the resource scheduling instruction containing indication information of the licensed resource determined by the reference information of the second parameter.
