    摘要: A method and apparatus for transmitting and receiving a common control channel in an Orthogonal Frequency Division Multiplexing (OFDM) mobile communication system. In the transmission apparatus, when a plurality of bursts are transmitted during a Transmission Time Interval (TTI) of the common control channel, an Inverse Fast Fourier Transform (IFFT) mapper generates bursts that are shifted in a frequency domain by applying a predetermined cyclic shift offset between the bursts, and maps the generated bursts in a resource block. A transmission unit transmits the bursts to a receiver. In the reception apparatus, a reception unit receives a burst, and a combining unit combines the received burst with a burst stored in a buffer. A decoder decodes each of the combined bursts, and upon a successful decoding, detects a TTI start timing of the common control channel from the successfully decoded burst.

    摘要: A method and apparatus for mapping coded data symbols to resources in a mobile communication system. An S/P converter converts a serial signal including user data or control information into a plurality of parallel signals. A DFT unit performs Discrete Fourier Transform (DFT) on the parallel signals output from the S/P converter. A controller controls the DFT unit so that among the signals output from the S/P converter, a control channel is mapped in the maximum available resources to which the control channel can be mapped, among the resources included in a resource block, and data symbols are mapped to the remaining resources, except for the maximum available resources to which the control channel can be mapped. A subcarrier mapper allocates the signals output from the DFT unit to subcarriers. An RF processor converts a signal output from the subcarrier mapper into a radio signal.

    摘要: A method and apparatus for transmitting a control channel of a base station in a mobile communication system. A downlink control channel signal generator generates a downlink control channel signal to be transmitted to a User Equipment (UE). A control channel candidate processor calculates a control channel decoding attempt order according to a state of the downlink channel. A controller determines a control channel candidate to be used, according to the calculated decoding attempt order. A mapper maps the generated control channel signal to the determined control channel candidate. A transmission processor wirelessly transmits the mapped signal.
