Method for setting power bias and carrying out system dispatching

The present invention relates to a system provided power offset and scheduling method, which is a core: According to high speed downlink shared channel HS-DSCH power distribution system and the HS-PDSCH channel spread code N, code channel for each transmission is determined power; the system allocates the common pilot transmission power of the CPICH, transmission power of each code channel and the pilot channel determined by setting a corresponding power offset of the CQI measurement. By the present invention, each code channel can transmit data at the same power, thus reducing transmit power and spreading code resources allocated to uncertainty and complexity of HSDPA users, and enable the user HSDPA transmission power is kept constant for a period of time to reduce the impact of power fluctuations HSDPA transmit CQI measurement; and flexible allocation of power and system can spreading code resources, dynamic resource management between R99 and HSDPA user; 16QAM when the terminal receives and demodulates the soft decision made, by directly CPICH measurement channel estimate accurately the relative received power, without the need for real-time measurement of the relative power offset.
