Abstract: Techniques for interference mitigation in a wireless communication system are disclosed. One example method includes receiving, at a first communication node, interference status information indicative of a remote interference between the first communication node and a second communication node and performing, by the first communication node, subsequent communications to the second communication node by implementing a backoff based on a granularity.

Abstract: Method, systems and devices for identifying and mitigating remote interference, e.g. a downlink transmission from a remote network device interfering with uplink transmissions of another network device, are described. One example method for identifying remote interference includes determining that an interference type is a remote interference, and transmitting, in response to the determining, a reference signal indicative of a resource that was affected by the remote interference. Another example method for identifying remote interference includes detecting a reference signal in a frame, and determining a resource that was affected by a remote interference based on a position of the reference signal in the frame.
