Method and apparatus ePDCCH resource element mapping in a communication network

The present invention provides a method and apparatus for performing resource element mapping for each ePDCCH user equipment served by the base station in a communication network, in particular, the base station first determines the resource element mapping patterns for each user equipment, and based on resource element mapping manner determined resource element mapping, wherein the resource element mapping pattern of resource elements comprises a trip signal has corresponding resource element mapping for the ePDCCH, or puncturing legacy signal resource elements corresponding to ePDCCH resource element mapping; downlink control signaling information and resource element mapping pattern is then determined for the base station is transmitted to each user device the respective user equipment. The present invention also provides a method and apparatus for decoding ePDCCH in a user equipment of a communication network; a size of the enhanced notify the user equipment resource element groups in a base station in a communication network; a method and a base station in a communication network the method of informing the user equipment for mapping mode.
