In a possible design, the cached data may include 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 design, the parameter associated with the cached data to be transmitted of the terminal may include 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 may include 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 design, the PUCCH resource may include at least one of: a short-duration PUCCH resource and a long-duration PUCCH resource.

According to a third aspect, the embodiments of the disclosure provide a terminal, which has a function of implementing operations of the terminal in the method design. The function may be realized through hardware and may also be realized by executing corresponding software through the hardware. The hardware or the software includes one or more modules corresponding to the function.

In a possible design, the terminal includes a processor, and the processor is configured to support the terminal to realize the corresponding function in the method. Furthermore, the terminal may further include a communication interface, and the communication interface is configured to support communication between the terminal and a network-side device. Furthermore, the network-side device may further include a memory, and the memory is configured to be coupled to the processor, and stores a necessary program instruction and data of the terminal.
