Embodiments of the present disclosure disclose devices and methods for sending and/or processing a scheduling request. The scheduling request sending method includes: determining whether there has a first scheduling resource configuration corresponding to the first logical channel according to first indication information, when the first logical channel of a terminal device has to-be sent data and a first scheduling request (SR) is triggered; where the first indication information includes a first mapping relationship which indicates a correspondence between a logical channel of the terminal device and a scheduling resource configuration, and the first scheduling resource configuration includes a first uplink control channel resource corresponding to the first logical channel; and sending the first SR to an access network device by the first uplink control channel resource, when the first logical channel has a corresponding first scheduling resource configuration.
