Based on the said system framework, to consult shown in Figure 5ly, in the embodiment of the invention, the detailed process of RNC indication UE adjustment target transmit power is following:
Step 500:RNC confirms at least one carrier wave that UE uses.
In the present embodiment, UE is in single carrier HSUPA state, also can be in the multi-carrier HSUPA state.
Step 510:RNC confirms the preset receiving demodulation thresholding that is used for right demodulation E-UCCH information of corresponding above-mentioned at least one carrier wave.

On the other hand; In the above-described embodiments; When RNC mails to UE with the receiving demodulation thresholding; Can adopt radio bearer to set up the enhancing physics uplink channel information (E-PUCH info) in the orders such as order (RadioBearerSetup), radio bearer reconfigure command (RadioBearerReconfiguration), physical channel reconfigure command (Physical Chanel Reconfiguration) or transmission channel reconfigure command (Transport Chanel Reconfiguration), with the receiving demodulation Threshold Notify UE of carrier wave.Consult shown in the table 1, the configuration mode of E-PUCH Info (is merely for example) as follows:
Table 1
Based on above-mentioned table 1, because with the receiving demodulation thresholding of UE on certain carrier wave (being a certain E-PUCH) (promptly in the table 1
PRRI Des E-UCCH ) notified UE, and the power authority that UE obtains on this carrier wave=
PRRI Des E-UCCH Therefore+Δ, has just notified UE with Δ, like this, UE according to based on
PRRI Des E-UCCH When the thresholding transmitting power that obtains is adjusted at the target transmit power on this carrier wave, just can be with reference to Δ, this point will describe in detail in flow.
Based on the foregoing description, to consult shown in Figure 6ly, in the embodiment of the invention, UE is following according to the detailed process of the local target transmit power of RNC indication adjustment:
Step 600:UE confirms local at least one carrier wave that uses.
In the present embodiment, UE is in single carrier HSUPA state, also can be in the multi-carrier HSUPA state.
Step 610:UE receives at least one receiving demodulation thresholding that network side sends, and this at least one receiving demodulation thresholding is used for the E-UCCH information of above-mentioned at least one carrier wave of right demodulation.
In the present embodiment, when execution in step 610, comprise but be not limited to following two kinds of situation:
In single carrier HSUPA; Promptly only use under the situation of a carrier wave at UE; The receiving demodulation thresholding that UE reception network side sends (can be known corresponding to step 510; At this moment, RNC only sends the receiving demodulation thresholding to single carrier), this receiving demodulation thresholding is used for the E-UCCH information of right demodulation single carrier; For example, UE obtains receiving demodulation thresholding A corresponding to single carrier.
In multi-carrier HSUPA; Promptly use under the situation of at least two carrier waves at UE; At least two receiving demodulation thresholdings that UE reception network side sends (can be known corresponding to step 510; At this moment, RNC sends the receiving demodulation thresholding to each carrier wave), above-mentioned at least two receiving demodulation thresholdings are respectively applied for the E-UCCH information of right demodulation corresponding carriers; For example, UE obtains receiving demodulation thresholding A and B respectively corresponding to carrier wave 1 and carrier wave 2.
Step 620:UE obtains corresponding thresholding transmitting power according to above-mentioned at least one receiving demodulation thresholding; And, make the not above-mentioned thresholding transmitting power of this target transmit power based on the target transmit power of this thresholding transmitting power this UE of adjustment on above-mentioned at least one carrier wave.
In the present embodiment, when execution in step 620, comprise equally but be not limited to following two kinds of situation:
In single carrier HSUPA; Promptly only use under the situation of a carrier wave at UE, UE according to the receiving demodulation thresholding of single carrier obtain corresponding thresholding transmitting power (as, adopt formula one to calculate); And the Initial Trans of UE on single carrier is set to this thresholding transmitting power; And, above-mentioned Initial Trans is carried out the increment adjustment based on the maximum transmission power of UE and the power headroom between the above-mentioned thresholding transmitting power, obtain the target transmit power on the single carrier; Wherein, the final objective transmitting power is not more than the mandate transmitting power that UE obtains on single carrier; For example: UE obtains corresponding thresholding transmitting power A1 according to the receiving demodulation thresholding A of single carrier, and with the Initial Trans P of this UE on single carrier
