7. The method according to claim 6 , wherein determining whether to use the preset priority sequence based on the priority identifier comprises:

determining to use the preset priority sequence when the priority identifier is a first character; or

determining not to use the preset priority sequence when the priority identifier is a second character.

8. The method according to claim 5 , wherein determining whether the priority of the uplink data is higher than the priority of the periodic BSR based on the priority of the logical channel to which the uplink data belongs and the priority of the logical channel to which the periodic BSR belongs comprises:

determining that the priority of the uplink data is higher than the priority of the periodic BSR when the priority of the logical channel to which the uplink data belongs is higher than the priority of the logical channel to which the periodic BSR belongs; and

determining that the priority of the uplink data is lower than the priority of the periodic BSR when the priority of the logical channel to which the uplink data belongs is lower than or equal to the priority of the logical channel to which the periodic BSR belongs.

9. The device according to claim 1 , wherein the configuration information further comprises a priority identifier.

10. A non-transitory computer-readable storage medium storing instructions that, when executed by a processor, cause the processor to:
