Abstract: 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.

Abstract: 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 as to whether the interference satisfies a threshold range of an analog-to-digital converter of the receiver for each of the group of transmitters. An analog time domain cancellation is performed responsive to a determination that the interference does not satisfy the threshold range, and a digital time domain cancellation is performed responsive to a determination that the interference satisfies the threshold range. Other embodiments are disclosed.

Abstract: 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.
