Consistent with the embodiment shown in FIG. 2, referring to FIG. 5, FIG. 5 is a structure diagram of a network-side device according to an embodiment of the disclosure. As shown in the figure, the network-side device includes one or more processors, a memory, a transceiver and one or more programs. The one or more programs are stored in the memory and are configured to be executed by the one or more processors. The programs include instructions configured to execute the following operations.

An SR configured to schedule cached data is received on a PUCCH resource determined by reference information of a second parameter, the second parameter being a parameter associated with the PUCCH resource used to transmit the SR.

A preset mapping relationship between information of a first parameter and information of a second parameter of a PUCCH resource is queried to acquire 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 a terminal.

A resource scheduling instruction for a licensed resource used to transmit the cached data is sent, the resource scheduling instruction containing indication information of the licensed resource determined by the reference information of the second parameter.
