    摘要: A method for mapping wireless resources of reference symbols for channel state estimation and modulation symbols for user information transmission in a transmitter of an Orthogonal Frequency Division Multiplexing (OFDM) mobile communication system is disclosed. The mapping method includes channel-encoding and modulating a user information stream to be transmitted, and then generating a systematic symbol stream and a parity symbol stream; and preferentially arranging systematic modulation symbols in resource elements of a symbol including no reference symbol, and then arranging parity modulation symbols in remaining resource elements.

    摘要: A method and apparatus for receiving control information in a mobile communication system. A controller acquires information indicating variable Control Channel Elements (CCEs) allocated for first User Equipments (UEs) among CCEs constituting control channels, acquires information indicating fixed CCEs allocated for second UEs, selects the variable CCEs when a UE receiving the control information is included in the first UEs, and selects the fixed CCEs when the UE is included in the second UEs. A control information receiver receives the control information through the selected CCEs.

    摘要: An apparatus and method for transmitting a control signal using a symbol or bit pattern of an existing pilot channel, instead of using the time multiplexing method in the separate code channel or the existing physical channel, and reducing an error rate while a reception side detects the control signal are provided. For that purpose, a transmission side allocates transmission power corresponding to a pilot pattern determined according to the control information. A corresponding reception side detects control information based on a pilot pattern of pilot bits inserted in a dedicated physical channel (DPCH) and generates transmit power control (TPC) bits referring to a target reception power which is set based on the control information.

    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.
