1. A method for remote interference management, the method comprising:
receiving, at a first device, an interference signal from a second device;
generating, at the first device, a reference signal including mitigation information for the remote interference management;
transmitting, by the first device, the reference signal to the second device; and
receiving, at the first device, a mitigation response signal indicative of a level of mitigation undertaken by the second device based on the mitigation information, the level of mitigation undertaken by the second device being based upon a number of symbols impacted by the interference signal that is estimated based upon an estimated length of a propagation delay experienced by the reference signal being transmitted by the first device and received at the second device.
 
9. A method for remote interference management, the method comprising:
receiving, at a second device, a reference signal from a first device, the reference signal being related to an interference signal received at the first device and including mitigation information for the remote interference management;
performing, by the second device, a mitigation based on the mitigation information, the performing comprising estimating a length of a propagation delay between the first device and the second device to estimate a number of symbols impacted by the interference signal, a level of the mitigation performed being based upon the number of symbols impacted by the interference signal that is estimated based upon the estimated length of the propagation delay; and
transmitting, by the second device, a mitigation response signal to the first device, the mitigation response signal indicating the level of the mitigation undertaken by the second device based on the mitigation information.
