BLIND DECODING FOR AN ENHANCED PHYSICAL DOWNLINK CONTROL CHANNEL (EPDCCH)

摘要

Technology for a user equipment (UE) configured for blind decoding downlink control information (DCI) from an enhanced physical downlink control channel (EPDCCH). 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. The resource elements (REs) of a PRB pair can include a block of symbols mapped in sequence to resource elements on an associated port when the REs are part of the EREGs assigned for the EPDCCH transmission.

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 the 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 are part of the EREGs assigned for the EPDCCH transmission.
