The embodiment of the invention provides the Poewr control method of a kind of E-HICH, as shown in Figure 1, comprising:
Step S101, obtain the transmitting power of user's appointment down control channel.
Step S102, according to the transmitting power of this appointment down control channel of obtaining, determine the transmitting power of this user's E-HICH.
Among the above-mentioned steps S102, specifically can be based on the default bias amount between the transmitting power of the transmitting power of specifying down control channel and this user's E-HICH, transmitting power according to this appointment down control channel that obtains, determine the transmitting power of this user's E-HICH, for example, the transmitting power of determining this user's E-HICH is the difference that the transmitting power of this appointment down control channel of obtaining deducts the default bias amount.
In the embodiment of the invention, it is more reasonable to the control of transmitting power to consider to adopt close-loop power control to compare open Loop Power control, so, for above-mentioned appointment down control channel, be specifically as follows the down control channel that adopts close-loop power control.
Better, in the down control channel that adopts close-loop power control, can select the descending DPCH of following (the Dedicated Physical Channel of user-specific, DPCH), in the HSPA system, system can be the DPCH that follows of each online this user-specific of HSPA user assignment, and this channel is used for this user's of transmission signaling information, with the reference as power control and wave beam forming.Because each user has the own exclusive DPCH that follows, therefore, can pay the utmost attention to and select the descending DPCH of following as above-mentioned appointment down control channel.
Yet, in the HSPA+ system, owing to cancelled and followed DPCH, so can consider to select other to adopt the down control channel of close-loop power control, for example, HS-SCCH (High Speed Shared Control Channel, High-Speed Shared Control Channel) and HS-SICH (High Speed Shared Information Channel, high-speed shared information channel) all is and HS-DSCH (High Speed Downlink Shared Channel, high-speed downlink shared channel) relevant channel, a pair of closed-loop power control channel, so can select wherein down control channel HS-SCCH as above-mentioned appointment down control channel.
And for example, E-PUCH (E-DCH Physical Uplink Channel, the E-DCH physical uplink channel) and E-AGCH (E-DCH Absolute Grant Channel, the E-DCH absolute grant channel) be a pair of closed-loop power control channel, so can select wherein down control channel E-AGCH 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 of following DPCH based on user-specific, the scheme that the transmitting power of user's E-HICH is controlled is described in detail in the embodiment of the invention 1.
In the 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 only is 1 bit, and this 1 bit information extends to 80bit with 80bit Hadmard orthogonal code, and finishes chnnel coding, interweaving and physical channel divides timing to fill the 8bit idle data subsequently, and adopting time slot format shown in Figure 2 to transmit the data of this 88bit.
Therefrom as can be known, the coding redundancy of E-HICH is very large, so its coding gain is also very large.So large coding gain can guarantee that UE also can finish correctly reading this bit information of ACK/NACK of E-HICH carrying in the relatively poor environment of channel quality.Therefore, the method for this time slot transmission power all being distributed to E-HICH that adopts has at present namely been wasted carrier power, more owing to distributed excessive transmitting power to cause interference to whole network for E-HICH, has reduced the total quality of network.
In the HSPA system, system can be the DPCH that follows of each online this user-specific of HSPA user assignment, and this channel is used for this user's of transmission signaling information, with the reference as power control and wave beam forming.Because each user has the own exclusive DPCH that follows, therefore, the descending transmitting power of following DPCH that the embodiment of the invention 1 proposes based on user-specific, the scheme that the transmitting power of user's E-HICH is controlled, specifically flow process as shown in Figure 1 above.
In above-mentioned steps S101, obtain the transmitting power of the descending DPCH of following of user-specific, and in above-mentioned steps S102, the transmitting power of determining this user's E-HICH is the difference that the transmitting power of this descending DPCH of following of obtaining deducts the default bias amount, and this default bias amount can be corresponding with the descending DPCH that follows.
Wherein, setting for the default bias amount, can arrange according to characteristic and the real network situation of the descending DPCH of following and E-HICH, for example, it is zero that this default bias amount can be set, and the transmitting power of the descending DPCH of following of this user-specific that is about to obtain is as the transmitting power of this user's E-HICH;
It is negative that this default bias amount also can be set, and the transmitting power of this user's who namely determines E-HICH is greater than the descending transmitting power of following DPCH of this user-specific;
Because the coding gain of E-HICH is much larger than the descending coding gain of following DPCH, be equal to or greater than the transmitting power of the descending DPCH of following of this user-specific so determine the transmitting power of this user's E-HICH, can guarantee that UE is to the accurate reception of the data of E-HICH carrying;
Yet, just because of the coding gain of E-HICH is much larger than the descending coding gain of following DPCH, therefore, better, it is positive number that this default bias amount can also be set, and the transmitting power of this user's who namely determines E-HICH is less than the descending transmitting power of following DPCH of this user-specific, thereby can reach the purpose of better saving carrier power, so that the descending interference that better minimizing produces the identical time slot in other residential quarter, and then the more effective network quality that improves integral body.

At above-mentioned steps S101, obtain the transmitting power of user's HS-SCCH, and in above-mentioned steps S102, the transmitting power of determining this user's E-HICH is the difference that the transmitting power of this HS-SCCH of obtaining deducts the default bias amount, and this default bias amount can be corresponding with HS-SCCH.
Wherein, setting for the default bias amount, can arrange according to characteristic and the real network situation of HS-SCCH and E-HICH, similar to the setting principle of default bias amount in above-described embodiment 1, for example, it is zero that this default bias amount can be set, it is negative that this default bias amount also can be set, because the coding gain of E-HICH is greater than the coding gain of HS-SCCH, be equal to or greater than the transmitting power of this user's HS-SCCH so determine the transmitting power of this user's E-HICH, can guarantee that UE is to the accurate reception of the data of E-HICH carrying; Better, it is positive number that this default bias amount can also be set, the transmitting power of this user's who namely determines E-HICH is less than the transmitting power of this user's HS-SCCH, thereby can reach the purpose of better saving carrier power, so that the descending interference that better minimizing produces the identical time slot in other residential quarter, and then the more effective network quality that improves integral body.
From in above-described embodiment 1 based on the scheme of the descending DPCH of following different be, because HS-SCCH is time-division sharing channel between the user, be not to be exclusive channel for each user assignment, so in same transmission subframe, this user's E-HICH may appear only existing, and do not have the situation of this user's HS-SCCH, so, for above-mentioned steps S101 following concrete processing mode is proposed in the embodiment of the invention 2:
