    摘要: 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).

    摘要: Technology to provide conditional physical uplink control channel (PUCCH) resource allocation in time division duplex (TDD) for a hybrid automatic retransmission request-acknowledge (HARQ-ACK) transmission in a subframe n is disclosed. In an example, a user equipment (UE) can include computer circuitry configured to: Receive a downlink control channel within a prior specified subframe, wherein the prior specified subframe occurs in time before the subframe n; recognize a downlink control channel type received within the prior specified subframe is a physical downlink control channel (PDCCH) or an enhanced physical downlink control channel (EPDCCH); determine a PUCCH resource for the HARQ-ACK transmission using a lowest control channel element (CCE) index of the PDCCH when the received downlink control channel type is the PDCCH; and determine the PUCCH resource for the HARQ-ACK transmission using a lowest enhanced CCE (ECCE) index of the EPDCCH when the received downlink control channel type is the EPDCCH.
