Abstract

According to the disclosure there is provided a method for the UE to mitigate Cell specific Reference Signal (CRS) interference (not only the other interference cells CRS interference but also the serving cell s CRS interference) during ePDCCH/PDSCH demodulation. In one non limiting embodiment a CRS interference mitigation method may include steps of: determining CRS having been configured is not serving cell s CRS; and mitigating interference originating from the serving cell s CRS by referring to serving cell s CRS configuration. The present disclosure also relates to a UE for implementing the above CRS interference mitigation method.
