Abstract
The invention provides a method and apparatus, in a base station of a communication network, for performing resource element mapping of an e PDCCH for respective user equipments served by the base station. Specifically the base station firstly determines resource element mapping patterns for the respective user equipments and performs the resource element mapping based upon the determined resource element mapping patterns, wherein the resource element mapping patterns include performing the resource element mapping for the e PDCCH by excluding resource elements corresponding to a legacy signal or performing the resource element mapping for the e PDCCH by puncturing the resource elements corresponding to the legacy signal; and then the base station sends information about the resource element mapping patterns determined for the respective user equipments and a downlink control signaling to the respective user equipments. The invention further provides a method and apparatus for performing e PDCCH decoding in a user equipment of a communication network; a method, in a base station of a communication network, of notifying a user equipment of a size of an enhanced resource element group; a method, in a base station of a communication network, of notifying a user equipment of a mapping pattern.
