Co-channel interference mitigation in wireless radio access network

摘要

Techniques described herein relate to reducing co-channel interference between macrocells and small cells in a heterogeneous network environment. Macrocells and small cells may dynamically select from among multiple interfaces (e.g., an X2 or S1 interface) to communicate FeICIC control communications. In one implementation, the selection may be based on the round trip delay (RTD) time between pairs of nodes. Thus, the macrocells and small cells nodes may dynamically select either the X1 or S1 interface based on whichever of these interfaces has the smallest RTD to the destination radio node.
