Claim:
1. An apparatus of a user equipment (UE) configured for blind decoding downlink control information (DCI) from an enhanced physical downlink control channel (EPDCCH), the apparatus comprising circuitry configured to: receive, from a base station, the EPDCCH that includes the DCI; and attempt one or more times to decode the DCI from enhanced control channel elements (ECCE) of the EPDCCH from physical resource block (PRB) region candidates in a PRB set using a selected set of enhanced resource element group (EREG) index maps for the ECCE until the DCI is successfully decoded, wherein resource elements (REs) of a PRB pair include a block of symbols mapped in sequence to resource elements on an associated port when the REs of the PRB pair are part of the EREGs assigned for the EPDCCH transmission.
