Based on above-mentioned table 1, due to the receiving demodulation door on certain carrier wave (being a certain E-PUCH) by UELimit is (in table 1PRRI des_E-UCCH ) notify UE, and the power authority that UE obtains on this carrier wave=PRRI des_E-UCCH + ⊿, therefore, have namely notified UE Jiang ⊿, like this, UE according to based onPRRI des_E-UCCH The thresholding transmitting power obtaining is while being adjusted at the target transmit power on this carrier wave, just can Can Kao ⊿, thisName a person for a particular job and describe in detail in follow-up flow process.
Based on above-described embodiment, to consult shown in Fig. 6, in the embodiment of the present invention, UE is according to RNC instruction tuneThe detailed process of whole local target transmit power is as follows:
Step 600:UE determines local at least one carrier wave using.
In the present embodiment, UE can be in single carrier HSUPA state, also can be in multicarrierHSUPA state.
Step 610:UE receives at least one receiving demodulation thresholding that network side sends, this at least one connectReceive the E-UCCH information of demodulation threshold for above-mentioned at least one carrier wave of correct demodulation.
In the present embodiment, execution step 610 o'clock, including but not limited to following two kinds of situations:
In single carrier HSUPA,, in the situation that UE only uses a carrier wave, UE receives network side(can know corresponding to step 510, now, RNC only sends for list the receiving demodulation thresholding sendingThe receiving demodulation thresholding of carrier wave), this receiving demodulation thresholding is for the E-UCCH information of correct demodulation single carrier;For example, UE, corresponding to single carrier, obtains receiving demodulation thresholding A.
In multi-carrier HSUPA,, in the situation that UE uses at least two carrier waves, UE receives network(can know corresponding to step 510, now, RNC sends pin at least two receiving demodulation thresholdings that side sendsTo the receiving demodulation thresholding of each carrier wave), above-mentioned at least two receiving demodulation thresholdings are respectively used to correctly separate phase modulationAnswer the E-UCCH information of carrier wave; For example, UE, corresponding to carrier wave 1 and carrier wave 2, obtains respectively to receive and separatesPitch limit A and B.
Step 620:UE obtains corresponding thresholding transmitting power according to above-mentioned at least one receiving demodulation thresholding,And adjust the target transmit power of this UE on above-mentioned at least one carrier wave based on this thresholding transmitting power, orderThe not above-mentioned thresholding transmitting power of this target transmit power.
In the present embodiment, performing step at 620 o'clock, equally including but not limited to following two kinds of situations:
In single carrier HSUPA,, in the situation that UE only uses a carrier wave, UE is according to single carrierReceiving demodulation thresholding obtain corresponding thresholding transmitting power (as, adopt formula one to calculate), and by UEInitial Trans on single carrier is set to this thresholding transmitting power, and emission maximum based on UEPower headroom between power and above-mentioned thresholding transmitting power, carries out increment tune to above-mentioned Initial TransWhole, obtain the target transmit power on single carrier, wherein, final target transmit power is not more than UE and existsThe mandate transmitting power obtaining on single carrier; For example: UE, according to the receiving demodulation thresholding A of single carrier, obtainsCorresponding thresholding transmitting power A1, and by this UE the Initial Trans P on single carrierInitiallyArrangeFor thresholding transmitting power A1, i.e. PInitially=A1, and the maximum transmission power of UE is Pmax, so, UECan be with reference to PmaxWith PInitiallyBetween power headroom (power headroom=Pmax－PInitially), to PInitiallyEnterThe increasing amount adjustment that row is certain, obtains target transmit power PTarget, i.e. PTarget=A1+ power increment, wherein,The power authority obtaining on single carrier due to UE is A+ ⊿, so its mandate transmitting power P obtainingAuthorize=A1+ ⊿, therefore, the span of above-mentioned power increment is [0 ， ⊿], like this, just can ensure PTarget≤PAuthorize, certainly, if Pmax<PAuthorize, PTarget≤Pmax＜PAuthorizeIf, PAuthorize<Pmax, PTarget≤PAuthorize, in a word, PTargetBe less than PAuthorizeAnd PmaxIn that less value.
In multi-carrier HSUPA, in the situation that UE can use at least two carrier waves, UE basisThe receiving demodulation thresholding of each carrier wave receiving obtains respectively corresponding thresholding transmitting power, and by UE at each yearInitial Trans on ripple is set to respectively corresponding thresholding transmitting power, and maximum based on UE is sent outPenetrate power and each thresholding transmitting power power and between power headroom, each Initial Trans is carried out respectivelyIncreasing amount adjustment, obtains the target transmit power on each carrier wave, wherein, and the target transmit power on arbitrary carrier waveBe not more than the mandate transmitting power that UE obtains on this arbitrary carrier wave; For example, UE connecing according to carrier wave 1Receive demodulation threshold A, obtain corresponding thresholding transmitting power A1, and according to the receiving demodulation door of carrier wave 2Limit B, obtain corresponding thresholding transmitting power B1, and by UD the initial transmissions on carrier wave 1 and carrier wave 2Power PInitial 1And PInitial 2Be set to respectively above-mentioned thresholding transmitting power A1 and B1, i.e. PInitial 1＝A1，PInitial 2=B1, and the maximum transmission power of UE is Pmax, so, UE can be with reference to PmaxWith (PJust Begin 1+PInitial 2) between power headroom (power headroom=Pmax－PInitial 1－PInitial 2), to PInitial 1And PInitial 2Carry out respectively certain increasing amount adjustment, thereby the target obtaining on carrier wave 1 and carrier wave 2 is separately sent outPenetrate power PTarget 1And PTarget 2, i.e. PTarget 1=A1+ power increment 1, PTarget 2=B1+ power increment2, wherein, the power authority obtaining on carrier wave 1 due to UE is A+ ⊿ 1, and UE is at carrier wave 1 soOn the mandate transmitting power P that obtainsAuthorize 1=A1+ ⊿ 1, and the power authority that UE obtains on carrier wave 2 isB+ ⊿ 2, the mandate transmitting power P that UD obtains on carrier wave 2 soAuthorize 2=B1+ ⊿ 2, therefore, onThe span of stating power increment 1 is [0 ， ⊿ 1], and the span of power increment 2 is [0 ， ⊿ 2], thisSample, just can ensure PTarget 1≤PAuthorize 1，PTarget 2≤PAuthorize 2, certainly, also to ensure P simultaneouslyTarget 1+PTarget 2≤Pmax。
In the above-described embodiments, for PInitial 1And PInitial 2While carrying out corresponding increasing amount adjustment, can be byAccording to the priority orders of carrier wave 1 and carrier wave 2, by power headroom=Pmax－PInitial 1－PInitial 2, at carrier wave1 and carrier wave 2 between distribute, thereby realize to PInitial 1And PInitial 2Increasing amount adjustment; Also can be according toDefault allocation proportion, by power headroom=Pmax－PInitial 1－PInitial 2, between carrier wave 1 and carrier wave 2Distribute, thereby realize PInitial 1And PInitial 2Increasing amount adjustment, can also adopt other modes, at thisRepeat no more.
On the other hand, for the situation that uses more than two carrier wave, can adopt equally aforesaid way to determineTarget transmit power on each carrier wave, does not repeat them here.
