Patent attributes
This application provides a resource scheduling method, an apparatus, and a system, and relates to the field of communications technologies, to meet scheduling requirements of data transmitted on different logical channels. The method includes: sending, by a terminal device, a BSR to an access network device, where the BSR carries first indication information, and the first indication information is used by the access network device to determine a scheduling mode corresponding to a first logical channel; receiving, by the terminal device, a first uplink grant resource sent by the access network device, where the first uplink grant resource is scheduled by the access network device based on the BSR in the scheduling mode; and sending, by the terminal device, to-be-sent data on the first logical channel to the access network device by using the first uplink grant resource.
