Abstract:
A method, an apparatus, and a computer program product for wireless communication are provided. In one configuration, the apparatus may be a UE. The apparatus may receive a message (e.g., via an ePCFICH) from an eNB and may process an ePDCCH using the message. The apparatus may receive a message via an ePCFICH indicating resources for ePDCCH, the ePDCCH being a localized ePDCCH and/or a distributed ePDCCH and process the ePDCCH using the message. The apparatus may receive an ePCFICH from an eNB, where the ePCFICH is a function of at least a PCI or a virtual cell identifier. The apparatus may process an ePDCCH using a default set of resources when an ePCFICH is not detected. The apparatus may receive an ePCFICH value and may determine either a starting symbol index for an ePDCCH or one or more ePDCCH resource sets based at least on the ePCFICH value.
