Abstract
Technology for blind decoding downlink control information (DCI) from an enhanced physical downlink control channel (EPDCCH) is disclosed. In an example, a user equipment (UE) can include a processor configured to: Recursively attempt 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; and decode the DCI with an EREG index map associated with a same aggregation level used to encode the DCI. Each EREG index map can be configured for a different aggregation level (AL).
