    摘要: An apparatus and method in which an Enhanced Uplink Dedicated transport CHannel (EUDCH) is used in a Wideband Code Division Multiple Access (WCDMA) system is provided. In a User Equipment (UE), when physical channels for transmitting EUDCH data are transmitted in addition to existing physical channels, a Peak-to-Average Power Ratio (PAPR) of an uplink transport signal increases. The increase in PAPR depends upon Orthogonal Variable Spreading Factor (OVSF) codes allocated to the corresponding physical channels and In-phase/Quadrature-phase (I/Q) channels. Therefore, the apparatus and method allocate optimum OVSF codes and I/Q channels to EUDCH-related physical channels in order to minimize an increase in PAPR due to EUDCH.

    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.
