In LTE-A or Rel. 10+, heterogeneous network deployments are supported to improve the user experienced link performance. However, such deployments give rise to new interference problems. In this study, macro-femto-cell interference scenarios for LTE-A downlink are investigated. We focus on the critical interference scenario of colliding cell-specific reference signals (CRSs). As conventional receivers with channel estimation based on the interfered CRSs fail to work properly, we present advanced… CONTINUE READING
