The present invention relates to a scheduling request transmission method, so as to effectively transmit a scheduling request when scheduling request resources are configured on multiple carriers. The terminal receives a configuration parameter for a scheduling request from a base station; when the scheduling request is triggered, the terminal sends the scheduling request on a selected one carrier of multiple carriers according to the configuration parameter. Scheduling request resources are assigned to the terminal on multiple carriers by sending the configuration parameter, so that the terminal can send the scheduling request on the selected one carrier of the multiple carriers according to the configuration parameter. This provides a solution to effectively transmitting the scheduling request.
