CONTROL CHANNEL INTERFERENCE MANAGEMENT FOR HETEROGENEOUS NETWORK VIA AN EXTENDED PDCCH

摘要

A method is provided for managing control channel interference. The method includes a first access node located within the coverage area of a second access node transmitting an E-PDCCH. The method further includes the first access node blanking a legacy control channel, wherein the second access node transmits the legacy control channel with the same nominal power as a downlink data channel, and wherein the E-PDCCH is defined within a downlink data channel region and transmitted by the first access node to carry downlink data channel and uplink data channel scheduling assignment information to UEs attached to the first access node.
