1. one kind is used for transmitting the power offset information of the relevant high-speed physical downlink shared channel (HS-PDSCH) in the floating radio network controller (DRNC) in order to obtain the subscriber equipment (UE) that is positioned at the residential quarter and method that the good channel performance between the Node B is indicated in following system, and described system comprises:

  • described Node B;

    Be connected to the described DRNC of described Node B, be used for managing the resource information of using with the UE signal post that is positioned at the residential quarter of being occupied by described Node B;

    And the service wireless network controller (SRNC) that is connected to described DRNC, being used for control message is sent to described UE, described method comprises the steps;

    Wireless link is set up request message, be sent to described DRNC from described SRNC;

    Determine described power offset information by DRNC based on the power of distributing to Common Pilot Channel and the ratio of distributing to the power of described high-speed physical downlink shared channel (HS-PDSCH), and the wireless link that will comprise determined power offset information is set up request message, is sent to described Node B from described DRNC;

    The wireless link that will comprise determined power offset information is set up response message, is sent to described SRNC from described DRNC;

    AndWith determined power offset information, be sent to described UE from described SRNC,Wherein said power offset information is the information of the ratio of the power of expression Common Pilot Channel (CPICH) and the power of high-speed physical downlink shared channel (HS-PDSCH) (HS-PDSCH), and be used to calculate channel quality identification (CQI) value of described HS-PDSCH with reference to described CPICHWherein said power offset information PO HsdschDetermine by following formula;

    Power Hsdsch=(maximum HSDPA gross power-maximum HS-SCCH power-surplus)/N PO hsdsch

    10log 10(Power hsdsch/Power cpich) Wherein, Power HsdschExpression is used for the power of each code of described high-speed physical downlink shared channel (HS-PDSCH) (HS-PDSCH), maximum HSDPA gross power represents to distribute to the gross power of high speed downlink grouping access business, maximum HS-SCCH power represents to distribute to the power of High-Speed Shared Control Channel (HS-SCCH), N represents the code sum for described HS-PDSCH, and Power CpichThe power of described Common Pilot Channel (CPICH) is distributed in expression.
