Claim:
1. At least one non-transitory computer readable medium having instructions stored therein for cancelling inter-node interference at a victim node, the instructions when executed on a machine to cause the machine to: receive downlink signal information at the victim node from an aggressor node; estimate a channel impulse response for a channel between the aggressor node and the victim node using the downlink signal information; estimate an inter-node interference signal for the channel using the downlink signal information and the channel impulse response; receive, at the victim node, an uplink signal from a wireless device, wherein the downlink signal information is received prior to the reception of the uplink signal; and subtract the estimated inter-node interference signal from the uplink signal to form an inter-node interference compensated uplink signal to substantially cancel inter-node interference caused by the aggressor node in the uplink signal received from the wireless device, wherein cancellation of the inter-node interference at the victim node enables the victim node to dynamically control a Time Division Duplexing (TDD) configuration based on downlink and uplink traffic asymmetry without inter-node interference from the aggressor node.
