Resource Scheduling Method, Apparatus, and System

A terminal device, comprising:

• a processor;
• and
• a computer-readable storage medium storing a program to be executed by the processor, the program including instructions for:
• generating a buffer status report (BSR), wherein the BSR carries first indication information, and the first indication information is used by an access network device to determine a scheduling mode corresponding to a first logical channel;
• sending the BSR to the access network device;
• and
• receiving a first uplink grant resource sent by the access network device, wherein the first uplink grant resource is scheduled by the access network device based on the BSR in the scheduling mode;
• and
• sending to-be-sent data on the first logical channel to the access network device using the first uplink grant resource.

An access network device, comprising:

• a receiver, configured to receive a buffer status report (BSR) sent by a terminal device, wherein the BSR carries first indication information;
• and
• a processor;
• and
• a computer-readable storage medium storing a program to be executed by the processor, the program including instructions for:
• determining, using the first indication information a scheduling mode corresponding to a first logical channel;
• and
• scheduling a first uplink grant resource based on the BSR in the scheduling mode, wherein the first uplink grant resource is allocated for the terminal device to use to send to-be-sent data.
