the second service group is a service group, different from the first service group, in the plurality of service groups.

8. The resource scheduling method according to claim 1 , wherein

the determining, by a device, a first scheduling request based on uplink data comprises:

determining, by the device, at least one service group corresponding to the uplink data; and

determining the first scheduling request corresponds to the first service group if the device determines that the first service group in the at least one service group has a highest priority.

9. A device, wherein the device comprises:

a non-transitory memory storage comprising instructions; and

a hardware processor in communication with the non-transitory memory storage, wherein the hardware processor executes the instructions to cause the device to perform:

determining a first scheduling request based on uplink data, wherein the first scheduling request corresponds to a first service group;

determining, based on the first service group, a first scheduling request resource used to send the first scheduling request, wherein the first service group is one of a plurality of service groups, and each of the plurality of service groups corresponds to one scheduling request resource;

sending the first scheduling request to a radio access network device using the first scheduling request resource, wherein the first scheduling request is used to request the radio access network device allocate an uplink resource;

determining that the first scheduling request resource and a fifth uplink resource overlap in a first time period, wherein the fifth uplink resource is used to carry uplink data that corresponds to a third service group and that is sent by the device to the radio access network device; and

determining that a priority of the third service group is higher than the priority of the first service group, and send the uplink data of the third service group by using the fifth uplink resource.
