System and method for full-duplex MAC timing modifications

摘要

A system, method, and computer-readable storage media for reducing monopolization of a frequency channel during full-duplex communications. The MAC layer of governing communications can be modified to reduce likelihood of monopolization by (1) in networks which are exclusively filled with full-duplex devices, configuring non-communicating devices to ignore data collisions of communicating devices, requiring the communicating devices to wait for an standard backoff time after the data transmission is complete; and/or (2) in mixed half-duplex/full-duplex networks, requiring a half-duplex nodes and/or a full-duplex node to wait an extended duration after the data transmission is complete, while the non-communicating devices do not wait an extended duration.

主权项

1. A method comprising:
determining, at a communication node, that the communication node is in full-duplex communication with a second node; determining, at the communication node, that an extended interframe space should be used rather than a distributed coordination function interframe space after a current data communication round between the communication node and the second node; and after receiving an acknowledgment of receipt of a successful transmission from the second node as part of the current data communication round, deferring contention in a distributed channel access protocol at the communication node for the extended interframe space, wherein the extended interframe space delays the communication node from entering a subsequent contention round with the second node relative to when the communication node would enter the subsequent contention round under the distributed coordination function interframe space.
