APPARATUS AND METHOD FOR ALLOCATING OVSF CODES AND I/Q CHANNELS FOR REDUCING PEAK-TO-AVERAGE POWER RATIO IN TRANSMITTING DATA VIA ENHANCED UP-LINK DEDICATED CHANNELS IN WCDMA SYSTEMS |
摘要 |
The present invention supposes a situation in which an Enhanced Uplink Dedicated transport Channel (EUDCH) is used in a Wideband Code Division Multiple Access (WCDMA) system. 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 present invention proposes an apparatus and method for allocating optimum OVSF codes and I/Q channels to EUDCH-related physical channels in order to minimize an increase in PAPR due to EUDCH. |
