In a possible example, on the aspect of acquiring the reference information of the first parameter required to be indicated to the network-side device, the instructions in the programs are specifically configured to execute the following operation: responsive to detecting that no UL-SCH resource is obtained to transmit the cached data, the reference information of the first parameter required to be indicated to the network-side device is acquired.

In a possible example, the cached data includes at least one of: data cached in an RLC layer of the terminal and data cached in a PDCP layer of the terminal.

In a possible example, the parameter associated with the cached data to be transmitted of the terminal includes any one of: a PHY-layer parameter numerology of the licensed resource used to transmit the cached data, a TTI duration of the licensed resource used to transmit the cached data and a data size of the cached data.

The second parameter includes at least one of: a resource type of the PUCCH resource, a resource block identifier of the PUCCH resource and a total number of repeated SR transmission times on the PUCCH resource.

In a possible example, the PUCCH resource includes at least one of: a short-duration PUCCH resource and a long-duration PUCCH resource.
