    摘要： A method for allocating physical resources to an Acknowledgement (ACK)/Negative Acknowledgement (NACK) signal channel representative of a response signal in a wireless communication system. The method includes grouping ACK/NACK signal channels corresponding to a plurality of resource blocks used for transmission of a data channel or a control channel into a plurality of groups so ACK/NACK signal channels having consecutive indexes do not belong to the same group; and allocating same frequency resources to ACK/NACK signal channels belonging to the same ACK/NACK signal channel group and allocating orthogonal sequences so ACK/NACK signal channels in each ACK/NACK signal channel group are distinguished in a code domain.

    摘要： A user equipment (UE) is configured to communicate with a plurality of base stations in a wireless network. The UE includes a processor that receive a downlink grant scheduling a physical downlink shared channel (PDSCH) for the UE, the downlink grant being transmitted in a physical downlink control channel (PDCCH) or an enhanced physical downlink control channel (ePDCCH). The processor also receives UE-specific demodulation reference signals (UE-RS) provided for demodulation of the PDSCH, wherein the UE-RS are scrambled according to a scrambling sequence initialized with an initialization value cinit. The downlink grant includes a one-bit scrambling identifier (SCID) information field configured to indicate a pair of values comprising a scrambling identifier nSCID and a virtual cell ID Nv-IDcell out of two candidate pairs, the pair of values to be used for determining the initialization value cinit for the UE-RS.

    摘要： A method for transmitting and receiving a control channel message in a mobile communication system using multiple antennas is provided. A base station determines whether a common pilot is used or a dedicated pilot is used. It also determines whether a corresponding Multiple Input Multiple Output (MIMO) mode is a Multi-CodeWord (MCW) MIMO mode or a Single CodeWord (SCW) MIMO mode, and determines whether knockdown precoding is used or ready-made precoding is used. The base station generates a control channel message field including a pilot pattern and a precoding type according to the determination results, and transmits the generated control channel message to the terminal. The terminal receives a control channel message transmitted from a base station. The terminal determines whether a common pilot is used or a dedicated pilot is used, whether a corresponding MIMO mode is an MCW MIMO mode or an SCW MIMO mode, and whether knockdown precoding is used or ready-made precoding is used. The terminal analyzes the control channel message field according to the determination results, and determines a data reception method according to the analysis result.
