Abstract
To address the problem of inter-cell interference in a heterogeneous network, several methods and systems are disclosed for determining interference caused by an aggressor mobile node, and transmitting at appropriate times and with transmit power that does not cause interference. Methods disclosed include using X2 communications, such as HII and RNTP messages, switching to an alternative radio access technology, sniffing at the eNodeB to obtain information, coordinating with a cloud coordination server, and using CFI information to avoid interfering with communications on the PDCCH.
