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： 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.

摘要： A system that incorporates the subject disclosure may include, for example, determining an interference based on a channel gain for each signal of a group of signals received at a receiver from a group of transmitters. A determination is made of an interference value based on a group of interference signals received at a receiver from a group of transmitters, wherein the interference value is based on channel gains that are estimated for the group of transmitters, and wherein a portion of the interference is self-interference generated from transmitting and receiving at a same time. One of an analog time domain cancellation, a digital time domain cancellation or both, is performed responsive to a determination that the interference value does not satisfy a threshold range of an analog-to-digital converter of the receiver. Other embodiments are disclosed.

摘要： Vehicle-to-vehicle and vehicle-to-infrastructure communications are accomplished via a scalable ad hoc geographic routing protocol. As vehicles move along roadways, they can query other vehicles and entities for information. Responses to queries can be used to determine information such as traffic conditions, a retail store sale, that a restaurant has tables available, and/or that parking spaces are available, for example. Businesses, vehicles, and other entities along roadways can geocast pertinent information to vehicles passing by. Vehicles can cache information as it is received.
