CENTRALLY-CONTROLLED INTER-CELL INTERFERENCE MITIGATION INTRODUCTION

WIPO Patent Application WO/2020/061721

A1

Certain aspects of the present disclosure provide techniques for performing interference mitigation. An exemplary method generally includes determining a first configuration for a first victim-aggressor pair including a first victim base station (BS) and a first aggressor base station (BS) to use to mitigate interference, wherein the first configuration indicates time and frequency resources for transmission of victim reference signals (RSs) by the first victim BS to indicate the presence of interference and for transmission of aggressor reference signals (RSs) by the first aggressor BS to indicate detection of victim RSs, wherein the first configuration is based at least in part on feedback from the first victim-aggressor pair and transmitting the first configuration to the first victim-aggressor pair.
