Abstract: A method and an apparatus are provided for determining whether an enhanced physical downlink control channel (ePDCCH) transmission exists for a user equipment (UE) in a subframe. The UE receives a transmission on physical downlink control channel (PDCCH) resources of the subframe. Downlink control information (DCI) is extracted from the PDCCH resources. The DCI includes at least one bit indicating whether the ePDCCH transmission exists for the UE in the subframe. The UE determines whether the ePDCCH transmission exists using the at least one bit. Additional symbols of the subframe are buffered and decoded when the ePDCCH transmission exists.
