摘要： Full-duplex communications are provided by modifying the Media Access Control sub-layer of communication node protocols. The modification allows communication nodes to communicate with one another in full-duplex, where each node transmits and receives data simultaneously with other nodes in a single frequency. A timing of the simultaneous data transmissions, acknowledgments, and short-interframe-space waiting periods can be determined based on network-allocation-vector data transmitted in association with request-to-send or clear-to-send signals.

摘要： Disclosed herein are systems, methods, and non-transitory computer-readable storage media for a modified MAC protocol which can facilitate communications with both full-duplex and half-duplex devices. A system configured according to the disclosed method can enable communications between an Access Point (AP) and a client in either full duplex or half duplex. The system can similarly enable peer-to-peer communications in both full duplex and half duplex communication modes.

摘要： Disclosed herein are systems, methods, and computer-readable storage devices for reducing inter-cellsite interference during full-duplex communication. A system receives a channel amplitude and a phase estimate between a first station and a second station, the first station and the second station creating inter-cellsite interference on a channel during full-duplex communications. The system calculates a level of the inter-cellsite interference between the first station and the second station based on the channel amplitude and the phase estimate and generates a cancellation signal based on the inter-cellsite interference. The system then communicates the cancellation signal to the first station for transmission with additional data during additional full-duplex communications.

摘要： Systems, methods, and computer-readable storage media for scheduling full-duplex communications between half-duplex mobile devices and a full-duplex capable access point. The system receives, within a time window, tones from a plurality of mobile devices, the tones indicating that each device in the plurality of devices are performing one of uploading data and downloading data. The system pairs the plurality of devices into pairs of an uploading device and a downloading device, where the pairing is based on an interference each device in the plurality of devices causes with remaining devices in the plurality of devices, to yield a list of paired devices. Upon communicating the list of paired devices to the plurality of devices, one device of each pair transmits data to the base station in a frequency channel while the other device receives data from the base station in the same frequency.

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.
