1. A method for wireless communication, comprising:
establishing, by a wireless network, time domain resources and frequency domain resources to implement wireless communication by a base station;
allocating an uplink resource and a downlink resource for communication between the base station and a user equipment device, the uplink resource and downlink resource each specified by a respective time domain resource and respective frequency domain resource, the frequency domain resource allocated to the uplink resource and the frequency domain resource allocated to the downlink resource allocated to enable full duplex communication;
performing, by the base station, communication with the user equipment device using the uplink resource and the downlink resource;
cancelling Cross Link Interference (CLI) on the uplink resource caused by a neighboring base station by further:
characterizing a communication path that introduces the CLI on the uplink resource;
informing, by the neighboring base station, of a downlink resource scheduling decision;
delaying, by the neighboring base station, a downlink resource transmission;
receiving, by the base station, the delayed downlink resource transmission; and
correcting transmissions received on the uplink resource based on the characterizing the communication path that introduces the CLI on the uplink resource and the delayed downlink resource transmission.
