Abstract: A method for configuring a search space of a downlink control channel is provided. The method includes determining the parameters for Enhanced Physical Downlink Control Channel (E-PDCCH) candidates of each aggregate level according to the number of Resource Elements (RE) in a subframe and/or the number of bits of Downlink Control Information (DCI) formats, when the parameters for E-PDCCH candidates of E-PDCCH search space is configured, determining, by a User Equipment (UE), the parameters for E-PDCCH candidates according to a current downlink subframe and a detected DCI format, and detecting blindly, by the UE, the E-PDCCH candidates in the E-PDCCH search space corresponding to the parameters for E-PDCCH candidates. The present invention also provides a UE and a base station. Application of the present invention can improve the flexibility of the base station scheduling, and reduce the possibility that the E-PDCCHs of different UEs block each other.

Abstract: A method and apparatus for performing uplink/downlink (UL/DL) transmission in a flexible subframe are provided. The method includes receiving downlink transmission configuration information in a flexible subframe that is different from configuration information of a subframe that has a fixed duplexing direction; detecting downlink control information transmitted by a base station in the flexible subframe; receiving downlink data corresponding to the downlink control information; and reporting Hybrid Automatic Repeat reQuest ACKnowledgment (HARQ-ACK) for the downlink data and downlink Channel State Indication (CSI) information to the base station.

Abstract: A method for configuring spatial diversity of an enhanced Physical Downlink Control CHannel (ePDCCH) is provided. The method includes alternately using, by each Resource Element (RE) in an enhanced Resource Element Group (eREG), one of NAP Antenna Ports (AP) by granularity of one RE, mapping each RE in a Physical Resource Block (PRB) pair to a fixed AP. The present disclosure further discloses a method for constructing a localized enhanced Control Channel Element (eCCE) and a method for constructing a distributed eCCE. The present disclosure further discloses devices respectively corresponding to above-mentioned methods. By use of the present disclosure, performance of spatial diversity of a distributed ePDCCH is improved and a number of the REs in the localized eCCE and the distributed eCCE are averaged to guarantee that link performance is uniform or close to each other.

Abstract: An apparatus and a method for transmitting/receiving a Physical Uplink Shared CHannel (PUSCH) signal in a cellular radio communication system supporting a Carrier Aggregation (CA) scheme are provided. In the PUSCH transmission method, a User Equipment (UE) transmits a PUSCH signal to a Base Station (BS) based on an UpLink (UL)/DownLink (DL) Configuration, wherein, for a Time Division Duplexing (TDD) scheme, if the UE is configured with more than one serving cell, UL/DL Configurations of at least two serving cells are different, and a serving cell is one of a primary cell and a secondary cell, a UL/DL Configuration for the serving cell is set as a UL-reference UL/DL Configuration based on a pair formed by a UL/DL Configuration for another serving cell and the UL/DL Configuration for the serving cell.
