Abstract: Systems, methods, and apparatuses for full duplex communication on a wireless network are disclosed. In one aspect, one or more lists of non-effecting nodes are determined for one or more devices on the wireless network. A list of non-effecting nodes for a device identifies other network nodes or devices whose transmissions do not cause substantial interference with the device.

This full duplex communication may be possible even if the device does not inherently support full-duplex communication on the wireless network.
