Unified coordination of multiple physical layer devices

A device comprising:

• a memory;
• and
• at least one processor configured to:
• receive a plurality of packets over a plurality of physical layer modules from another device;
• generate a block acknowledgment packet that indicates that the plurality of packets have been received from the another device;
• defer transmission of the block acknowledgement packet when a size of a retransmission buffer at the another device satisfies an acknowledgment deferral factor;
• select one of the plurality of physical layer modules for transmission of the block acknowledgment packet;
• and
• provide the block acknowledgment packet to the selected one of the plurality of physical layer modules for transmission to the another device.

A computer program product comprising code stored in a non-transitory computer-readable storage medium, the code, when executed by one or more processors, causes the one or more processors to perform operations comprising:

• receiving a plurality of packets over a plurality of physical layer modules from another device;
• generating a block acknowledgment packet that indicates that the plurality of packets have been received from the another device;
• deferring transmission of the block acknowledgement packet when a size of a retransmission buffer at the another device satisfies an acknowledgment deferral factor;
• selecting one of the plurality of physical layer modules for transmission of the block acknowledgment packet;
• and
• providing the block acknowledgment packet to the selected one of the plurality of physical layer modules for transmission to the another device.
