Abstract

Interference mitigation solutions are disclosed for interference experienced based on asymmetric uplink (UL)/downlink (DL) slot configuration. The aggressor/victim network entities are identified using either measurement or static/semi-static means, such that the victim network entities that may be impacted by interference from aggressor network entity transmissions are identified. Inter Cell Interference Coordination (ICIC) mechanisms are extended to negotiate and address scheduling that intelligently mitigates interference that occurs in the colliding slots.
