Claim Text:
1. A method for providing, by a receiving apparatus (UE) configured with at least one serving cell including a primary cell, simultaneously feedback on reconfiguration attempts of search spaces for enhanced physical downlink control channels (E-PDCCH) and feedback on at least one downlink transmission to a transmitting apparatus (eNB), the method comprising the following steps performed by the receiving apparatus (UE): receiving the at least one downlink transmission via the at least one serving cell from the transmitting apparatus, receiving from the transmitting apparatus reconfiguration information for reconfiguration of the search spaces for the at least one serving cell, determining for the at least one downlink transmission whether the received downlink transmission is successfully decodable, and determining whether the received reconfiguration information is successfully decodable, generating a feedback tuple including ACK/NACK/DTXs determined based on the successful/un-successful decoding of the at least one downlink transmission and including ACK/DTXs determined based on the successful/un-successful decoding of the reconfiguration information, transmitting the feedback tuple as a combination of: a selected one of a plurality of uplink resources available for transmitting the feedback tuple via the primary cell, and a selected one of a plurality of modulation symbols of a modulation scheme for transmission on the selected uplink resource.
