Medium Access Control Circuit, Data Processing Method, and Related Device

A communications device comprising:

• an antenna;
• and
• a medium access control (MAC) circuit coupled to the antenna, wherein the MAC circuit includes:
• a number (N) of hardware queues divided into a plurality of hardware queue groups, wherein each hardware queue group comprises a plurality of hardware queues, wherein a total quantity of hardware queues in the plurality of hardware queue groups is less than or equal to N, and wherein the N hardware queues are configured to store a to-be-sent data frame;
• a processor connected to the N hardware queues wherein the processor is configured to place a data frame in a first hardware queue in a first hardware queue group the hardware queue groups, wherein the first hardware queue group corresponds to a network property of the data frame based on a first mapping relationship, wherein the first hardware queue corresponds to a service type of the data frame based on a second mapping relationship, wherein the first mapping relationship comprises mappings from a plurality of network properties to the plurality of hardware queue groups, and wherein and the second mapping relationship comprises mappings from a plurality of service types to a plurality of hardware queues in the first hardware queue group corresponding to the network property of the data frame;
• and
• an interface circuit connected to the N hardware queues, wherein the interface circuit is configured to send the data frame from the N hardware queues through a radio channel.
