Interference Mitigation Methods for LTE-Advanced Networks with Macro and HeNB Deployments

This paper is focused on interference mitigation for LTE-Advanced multi-layer networks with macro and HeNBs. The autonomous HeNB power setting in the downlink is studied for different HeNB access methods. Our studies show that using the so-called escape carrier configuration and autonomous HeNB power setting is a promising strategy for enabling gradual introduction of user-deployed HeNBs in existing macro-layer networks.
