ENHANCED CONTROL CHANNEL INTERFERENCE COORDINATION AND AVOIDANCE

摘要

Reliable decoding of control channels can be important in Long Term Evolution/Long Term Evolution Advanced (LTE/LTE-A) networks. Methods are provided for intercell interference coordination of control channels in LTE networks. Dense deployments of heterogeneous and small cell networks can increase interference and further degrade control channel (CC) reception. With coordination between base stations, interference to legacy or enhanced control channels can be mitigated. However, the overhead and periodicity of coordination can be dependent on the inter-eNB backhaul link quality. Implementations are provided for CC ICIC, under various backhaul quality assumptions.
