In a possible example, after the operation that the terminal transmits the SR used to schedule the cached data, on the PUCCH resource determined by the reference information of the second parameter, the method further includes that: the terminal receives the cached data on the licensed resource determined by the reference information of the first parameter.

After the operation that the network-side device sends the resource scheduling instruction for the licensed resource used to transmit the cached data, the method further includes that: the network-side device receives the cached data on the licensed resource determined by the reference information of the second parameter.

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.

The embodiment of the disclosure will specifically be described below in combination with specific application scenarios.
