The transmitting power of the appointment down control channel of step S101, acquisition user.
Step S102, according to the transmitting power of this appointment down control channel obtained, determine the transmitting power of the E-HICH of this user.
In above-mentioned steps S102, specifically can based on the default bias amount of specifying between the transmitting power of down control channel and the transmitting power of the E-HICH of this user, according to the transmitting power of this appointment down control channel obtained, determine the transmitting power of the E-HICH of this user, such as, determine that the transmitting power of the E-HICH of this user is the difference that the transmitting power of this appointment down control channel obtained deducts default bias amount.
In the embodiment of the present invention, consider to adopt close-loop power control to compare open Loop Power control more reasonable to the control of transmitting power, so, for above-mentioned appointment down control channel, be specifically as follows the down control channel adopting close-loop power control.
Preferably, in the down control channel adopting close-loop power control, the descending with DPCH (Dedicated Physical Channel of user-specific can be selected, DPCH), in HSPA system, system can distribute adjoint the DPCH of this user-specific for each online HSPA user, this channel for transmitting the signaling information of this user, using the reference as power control and wave beam forming.Due to the adjoint DPCH that each user has oneself exclusive, therefore, the descending adjoint DPCH of selection can be paid the utmost attention to as above-mentioned appointment down control channel.
But, in HSPA+ system, owing to eliminating with DPCH, so can consider to select other to adopt the down control channel of close-loop power control, such as, HS-SCCH (High Speed Shared ControlChannel, High-Speed Shared Control Channel) and HS-SICH (High Speed Shared InformationChannel, high-speed shared information channel) be all and HS-DSCH (High Speed Downlink SharedChannel, high-speed downlink shared channel) relevant channel, a pair closed-loop power control channel, so down control channel HS-SCCH wherein can be selected as above-mentioned appointment down control channel.

Below in conjunction with accompanying drawing, with specific embodiment, method provided by the invention and device are described in detail.
Embodiment 1:
To the descending transmitting power with DPCH based on user-specific in the embodiment of the present invention 1, the scheme that the transmitting power of the E-HICH of user controls is described in detail.
In TD-SCDMA system, the cataloged procedure of E-HICH channel as shown in Figure 2, wherein, E-HICH is used for NodeB feeds back ACK/NACK information from each corresponding E-DCH transmission block to UE, information bit length is only 1 bit, and this 1 bit information 80bit Hadmard orthogonal code extends to 80bit, and completes chnnel coding, fill 8bit idle data when interweaving and physical channel distributes subsequently, and adopt the time slot format shown in Fig. 2 to transmit the data of this 88bit.
Therefrom known, the coding redundancy of E-HICH is very large, so its coding gain is also very large.So large coding gain can ensure that UE also can complete the correct reading of this bit information of ACK/NACK to E-HICH carrying in the poor environment of channel quality.Therefore, the method this time slot transmission power all being distributed to E-HICH adopted at present, namely wastes carrier power, more causes the interference to whole network owing to being assigned with excessive transmitting power for E-HICH, reduce the total quality of network.
In HSPA system, system can distribute adjoint the DPCH of this user-specific for each online HSPA user, this channel for transmitting the signaling information of this user, using the reference as power control and wave beam forming.Due to the adjoint DPCH that each user has oneself exclusive, therefore, the embodiment of the present invention 1 proposes the descending transmitting power with DPCH based on user-specific, to the scheme that the transmitting power of the E-HICH of user controls, and specifically flow process as shown in Figure 1 above.
In above-mentioned steps S101, obtain the descending transmitting power with DPCH of user-specific, and in above-mentioned steps S102, determine that the transmitting power of the E-HICH of this user is the difference that this descending transmitting power with DPCH obtained deducts default bias amount, this default bias amount can be corresponding with DPCH with descending.
Wherein, for the setting of default bias amount, can arrange according to the descending characteristic with DPCH and E-HICH and real network situation, such as, can arrange this default bias amount is zero, is about to the transmitting power of transmitting power as the E-HICH of this user of the descending adjoint DPCH of this user-specific obtained;
Also can arrange this default bias amount is negative, and the transmitting power of the E-HICH of this user namely determined is greater than the descending transmitting power with DPCH of this user-specific;
Because the coding gain of E-HICH is much larger than the descending coding gain with DPCH, so determine that the transmitting power of the E-HICH of this user is equal to or greater than the descending transmitting power with DPCH of this user-specific, the accurate reception of UE to the data that E-HICH carries can be ensured;
But, just because of the coding gain of E-HICH is much larger than the descending coding gain with DPCH, therefore, preferably, can also arrange this default bias amount is positive number, and the transmitting power of the E-HICH of this user namely determined is less than the descending transmitting power with DPCH of this user-specific, thus can reach the object of better saving carrier power, so that the descending interference that better minimizing produces the identical time slot in other community, and then the more effective network quality improving entirety.
