It can be seen that, in the embodiment of the disclosure, the terminal acquires the reference information of the first parameter required to be indicated to the network-side device at first, then 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 first parameter, of the second parameter of the PUCCH resource and finally transmits the SR used to schedule the cached data, on the PUCCH resource determined by the reference information of the second parameter. Since the information of the first parameter forms the mapping relationship with the information of the second parameter, the SR may be transmitted to enable the network-side device to acquire the reference information, corresponding to the reference information of the second parameter, of the first parameter at the same time of receiving the SR and further learn configuration information of the licensed resource used to transmit the cached data, and no additional signaling overhead is required to transmit the configuration information of the licensed resource. Therefore, improvement in SR transmission flexibility of a wireless communication system and improvement in resource scheduling efficiency of the data transmission channel in the wireless communication system are facilitated.

In a possible example, the programs further include an instruction configured to execute the following operation: before the reference information of the first parameter required to be indicated to the network-side device is acquired, the cached data is acquired.
