Blind decoding for an enhanced physical downlink control channel (EPDCCH)
First Claim
1. At least one non-transitory machine readable storage medium having instructions embodied thereon for blind decoding downlink control information (DCI) from an enhanced physical downlink control channel (EPDCCH), the instructions when executed by one or more processors of a user equipment (UE) perform the following:
- processing, at the UE, the EPDCCH received from a base station, wherein the EPDCCH includes the DCI; and
attempting 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.

Abstract
Technology for a user equipment (UE) configured for blind decoding downlink control information (DCI) from an enhanced physical downlink control channel (EPDCCH) is disclosed. The UE can receive, from a base station, the EPDCCH that includes the DCI. The UE can 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.

11. A user equipment (UE) operable to blindly decode downlink control information (DCI) from an enhanced physical downlink control channel (EPDCCH), the UE comprising:
-
a transceiver configured to receive the EPDCCH from a base station, wherein the EPDCCH includes the DCI; and one or more processors configured to 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. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)

21. At least one non-transitory machine readable storage medium having instructions embodied thereon for blind decoding downlink control information (DCI) from an enhanced physical downlink control channel (EPDCCH), the instructions when executed by one or more processors of a user equipment (UE) perform the following:
-
processing, at the UE, the EPDCCH received from a base station, wherein the EPDCCH includes the DCI; attempting 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 the DCI is decoded with an EREG index map associated with a same aggregation level used to encode the DCI; and failing to decode the DCI when an assumed aggregation level differs from an encoded aggregation level, wherein the processor attempts to decode with an EREG index map associated with the assumed aggregation level, and the encoded aggregation level is the same aggregation level used by the base station to encode the DCI for transmission in the EPDCCH, wherein resource elements (REs) of a PRB pair include a block of symbols mapped in sequence to REs on an associated port when the REs of the PRB pair are part of EREGs assigned for the EPDCCH transmission. - View Dependent Claims (22, 23, 24, 25)
