In order to UE transmit power progress more accurately adjustment, in technique proposed herein scheme of the embodiment of the present invention, processor is first adjusted the special used for physical control channel DPCCH transmit power of user equipment (UE) to the first transmit power by initial power by the first power step size, then the second power step size different from the first power step size is passed through, DPCCH transmit powers are adjusted to the second transmit power by the first transmit power, and transmitter then sends data by the first transmit power or the second transmit power to network side equipment, compared in the prior art only by way of a kind of power step size is adjusted to DPCCH transmit powers, the present invention can be adjusted for the different adjusting stages using different power step sizes to DPCCH transmit powers here, and then to the more more accurate of DPCCH transmit powers, and it ensure that the signal-to-noise ratio of DPCCH determined by base station（ SIR:Signal to Interference Ratio) target sir can be converged to as early as possible.

To the main realization principle of technical scheme of the embodiment of the present invention, embodiment and its beneficial effect that should be able to be reached is set forth in below in conjunction with each accompanying drawing.

In a first aspect, the embodiment of the present invention provides a kind of UE, Fig. 1 is refer to, is specifically included：Processor 10, for determining the first power step size,

The special used for physical control channel DPCCH transmit power of user equipment (UE) is adjusted to the first transmit power by initial power using the first power step size；And

It is determined that second power step size different from the first power step size,

DPCCH transmit powers are adjusted to the second transmit power by the first transmit power using the second power step size；

Transmitter 11, is connected to processor, for by the first transmit power and/or the second transmit power to Network side equipment send data, namely can by least one of the first transmit power and the second transmit power transmit power to network side equipment send data.

In specific implementation process, UE also includes：Receiver, is connected to processor 10, for it is determined that before the first power step size, receiving the power headroom that network side equipment is sent.Network side equipment is, for example,：Base station, radio network controller（RNC:Radio Network Controller) etc..

Processor 10, is additionally operable to：Reference power is obtained, and initial power is determined according to reference power and power headroom.

Due to when UE switches or when UE does not send data for a long time, base station can not determine that UE starts to send used DPCCH initial powers, so, in initial transmission phase, need to determine suitable DPCCH initial power for UE, to ensure before the AG of network side equipment transmission is not received by, data can be also sent, and then improve resource utilization.

In specific implementation process, network side equipment can be by signaling to UE transmit power surpluses.

And the DPCCH in the present invention can configure main carrier and secondary carrier, and then the program is set to be applied to dual carrier system, in this case, reference power is, for example,：The current power of main carrier or the descending pilot frequency power of secondary carrier etc., both power can be detected that, for which kind of mode to obtain reference power using, the embodiment of the present invention is not restricted by UE oneself.

When the current power of main carrier is current ascending power, because the current upstream frequency of main carrier and the frequency interval of secondary carrier are smaller, and UE sends DPCCH by secondary carrier under normal circumstances, so ensure that identified DPCCH initial powers are more accurate.

Processor 10, can obtain initial power, for example by way of power headroom and reference power are made into linear operation：Initial power is obtained by below equation：

Pini = P_reF-power-margin [1] wherein, P_miRepresent initial power；

P_refRepresent ginseng power；

Power-margin represents power headroom.

Pass through such scheme, it is ensured that UE switching after, or UE a period of time in do not carry out data transmission after, also can quickly determine initial power, without wait network side equipment determination UE initial power, and then after switching or not carrying out data transmission in a period of time initial power can be determined as early as possible, so as to reach the technique effect for making full use of available network to load.

Processor 10 can determine the first power step size in several ways, be set forth below two kinds therein and be introduced, and certainly, in specific implementation process, be not limited to following two situations.

In first way, receiver specifically for：Receive and the first power step size is included in the power control commands word sent by network side equipment, power control commands word；

Processor 10, specifically for：The first power step size is obtained from receiver.

After UE determines initial power, transmitter 11 is sent with initial power to network side equipment

DPCCH。

Network side equipment estimates DPCCH signal-to-noise ratio after DPCCH is received（ SIR:

Signal to Interference Ratio), then with target sir^SIRtIt is compared, and then produces the power control commands word of lifting power, is sent to the adjustment that UE carries out power.For example：If DPCCH SIR with⁵^ differences are larger, and network side equipment then determines to use the first larger power step size；And if DPCCH SIR with⁵^ differences are smaller, and network side equipment then determines, using less first power step size etc., so to ensure that and DPCCH SIR is converged into ^ as early as possible.If wherein SIR is higher than ^, the power control commands word of reduction power is produced, if SIR is less than, the power control commands word of increase power is produced.

In the second way, processor 10 specifically for：The quotient obtained after the absolute value divided by n of the power headroom that network side equipment is sent is defined as the first power step size, and n is preset value.

Optionally, processor 10 is specifically additionally operable to：First power step size is quantified, the first power step size after being quantified.

Optionally, the n is specially：UE carries out the time delay timeslot number that Enhanced-DedicatedChannel Dedicated Physical Data Channel E-DPDCH data are sent using authorization of service SG for the first time, the timeslot number of the DPCCH prefixes or timeslot number of DPCCH prefixes and one fixes timeslot number sum when being DPCCH discontinuous transmissions when being either DPCCH discontinuous transmissions.

Under normal circumstances, 2ms Transmission Time Interval（ TTI: Transmission Time Interval ) Equal to 3 time slots, if the delay packet that E-DPDCH data are sent is containing 5 TTI, it is 15 to prolong timeslot number at that time, then can determine that the first power step size is： power— margin/15.

Optionally, receiver can also receive the power control commands word that instruction is lifted comprising power of network side equipment transmission, and then can determine the first transmit power by the first power step size and power lifting instruction, for example：If power lifting instruction is the instruction of reduction power, subtract the first power step size to obtain the first transmit power by initial power；If power lifting instruction is the instruction of increase power, increase by the first power step size to obtain the first transmit power by initial power.

Wherein, if the first power step size is sent to UE by network side equipment by power control commands word, instruction not only can be lifted comprising the first power step size but also comprising power in the power control commands word；And if the first power step size is determined by UE sides, then only lift instruction comprising power in power control commands word.

Optionally, UE can be adjusted with the power step size of multipass first to initial power, and then determine the first transmit power.

Optionally, receiver is additionally operable to：Receive and the second power step size is included in the power control commands word sent by network side equipment, power control commands word；

Processor 10, specifically for：The second power step size is obtained from receiver.

In specific implementation process, UE is sent to network side equipment by the first transmit power first

DPCCH;Network side equipment is estimated DPCCH SIR, is then compared with target sir after DPCCH is received, and then the power control commands word of generation lifting power, if wherein

SIR is higher than⁵The power control commands word of reduction power is then produced, if SIR is less than⁵Then produce the power control commands word of increase power.Finally, network side equipment sends the power control commands word that instruction and the second power step size are lifted comprising power to UE.

And UE sides are after the power control commands word that instruction and the second power step size are lifted comprising power is received, processor 10 determines the second transmit power again by the power lifting instruction included in power control commands word, for example：If power lifting instruction is the instruction of increase power, the second transmit power is determined by way of the second power step size adds the first transmit power；If power lifting instruction is the instruction of reduction power, second transmit power etc. is determined by the transmission of the second power step size transmit power that subtracts the first. Similarly, processor 10 can be adjusted with the power step size of multipass second to the first transmit power, and then determine the second transmit power.And, due to being adjusted by the second power step size to DPCCH transmit powers after being adjusted by the first power step size to DPCCH transmit powers, so refinement information is generally fallen into, so that the second power step size is typically smaller than the first power step size, such as：First power step size is that 2dB, the second power step size are IdB, naturally it is also possible to be other values, and the embodiment of the present invention is not restricted.

As shown in Figure 2 a and 2 b, wherein for simplicity in Fig. 2 a and Fig. 2 b, p represents initial power, stepl represents the first power step size, and step2 represents the second power step size, and the second power step size that step2 is represented is less than the first power step size that stepl is represented.

When Fig. 2 a indicate to send the power control commands word of the second power step size of power control commands word and transmission of the first power step size comprising increase power, schematic diagram is adjusted to power.

Initial power p is determined first, then transmitter 11 sends DPCCH to network side equipment by initial power p, and network side equipment detects DPCCH SIR, determine that it compares^SIRtIt is small, and SIR differs that amplitude is larger with ^^, so the power control commands word of increase power is sent, wherein including stepl, DPCCH transmit powers are adjusted to p+ ste l by UE processor 10 after power control commands word is received by receiver by initial power;

Then UE transmitter 11 sends DPCCH by p+ stepl to network side equipment, and network side equipment detects DPCCH SIR, determines that it compares⁵It is small, and to differ amplitude with ^^ larger by SIR, for example：UE sides initial powers sets too low, or to run into channel fading just larger, then SIR can be caused larger with the amplitude of differing, SIR be, for example, -12dB,⁷^g is, for example, 8dB;So the power control commands word of increase power is sent, wherein comprising stepl, DPCCH transmit powers are adjusted to the X stepl of p+ 2 by UE processor 10 after power control commands word is received by receiver by initial power p;

Then UE transmitter 11 sends DPCCH by the X stepl of p+ 2 to network side equipment, and network side equipment detects DPCCH SIR, determines that it is smaller than spending, so power step size is adjusted to by stepl^S s^It^Rep^tIt is small, and SIR with

2, and then send increase work(^SRate^IRThe power control commands word of ^ phase spreads, wherein comprising step2, UE processor 10 after power control commands word is received by receiver, DPCCH transmit powers are adjusted to the X ste l+ step2 of p+ 2 by initial power p;

Then UE transmitter 11 sends DPCCH by the X stepl+ step2 of p+ 2 to network side equipment, and network side equipment detects DPCCH SIR, determines that it compares^SIRtIt is small, and SIR with

For example：If the X of p+ 2^SIR^ difference amplitudes are smaller, and ste l+ step2 transmit power is just suitable, or channel fading is just smaller, just SIR fluctuated near SIRtarget, then SIR can be made just to be slightly less than

^SIRtSIR is, for example, 7dB, is, for example, 8dB, so continue to send the power control commands word of increase power, wherein include step2, DPCCH transmit powers are adjusted to the X step 1+2 step2 of p+ 2 by UE processor 10 after power control commands word is received by receiver by initial power p;The rest may be inferred.

When Fig. 2 b indicate to send the power control commands word of the second power step size of power control commands word and transmission of the first power step size comprising reduction power, schematic diagram is adjusted to power.

Initial power p is determined first, then UE transmitter 11 sends DPCCH to network side equipment by initial power p, and network side equipment detects DPCCH SIR, determine that it compares⁵Greatly, and SIR differs that amplitude is larger with ^, so the power control commands word of reduction power is sent, wherein including stepl, DPCCH transmit powers are adjusted to P- ste l by UE processor 10 after power control commands word is received by receiver by initial power;

Then UE transmitter 11 sends DPCCH by P- stepl to network side equipment, and network side equipment detects DPCCH SIR, determines that it compares⁵Greatly, and SIR with⁷^ difference amplitudes are larger, such as UE sides initial power sets excessive, to cause network side equipment to determine SIR ratios⁵Difference amplitude is larger, and SIR is, for example,：15dB, for example, 2dB, so the power control commands word of reduction power is sent, wherein including stepl, DPCCH transmit powers are adjusted to the X stepl of P- 2 by UE processor 10 after power control commands word is received by receiver by initial power p;

Then UE transmitter 10 sends DPCCH by p-2 stepl to network side equipment, and network side equipment detects DPCCH SIR, determines that it compares^SIRtGreatly, and SIR with

, so power step size is adjusted into step2 by stepl, and then send reduction work(^SRate^IR^ differs the less power control commands word of amplitude, Step2 is wherein included, DPCCH transmit powers are adjusted to the X ste l-step2 of P- 2 by UE processor 10 after power control commands word is received by receiver by initial power p;

Then UE transmitter 11 sends DPCCH by the X stepl- step2 of P- 2 to network side equipment, and network side equipment detects DPCCH SIR, determines that it compares^SIRtGreatly, and SIR with

816 1^6 2 transmit power is just suitable,^SIROr ^ difference amplitudes are smaller, for example：Less, in this case, SIR may be slightly larger than the person of transmit power -2 channel fading⁵^a^, SIR are, for example,： 3dB、^SIRtFor example,：2dB, so continue to send the power control commands word of reduction power, wherein comprising step2, UE processor 10 is after power control commands word is received by receiver, DPCCH transmit powers are adjusted to the X step 1-2 χ step2 of P- 2 by initial power p, analogized according to J.

Processor 30, is additionally operable to：It is determined that the power control commands word comprising the second power step size；

Transmitter 31, is additionally operable to：Power control commands word comprising the second power step size is sent to user equipment (UE), so that UE is adjusted the first transmit power to the second transmit power by the second power step size, wherein, the first power step size is different power step sizes from the second power step size.

Optionally, processor 30, are additionally operable to determine the first power step size；

As shown in figure 5, being Enhanced-DedicatedChannel（E-DCH:Enhanced Dedicated Channel) Dedicated Physical Data Channel（E-AGCH ：E-DCH Dedicated Physical Data Channel) send and application timing diagram, switched to by UE3 after UE1, network side equipment send first absolute grant（ AG:Absolute grant) to be delayed at one section（After being 5 Τ such as Fig. 5）, i.e., second #0 TTI can just come into force, and AG is commonly referred to as the SG being carried on E-AGCH channels, and SG, which characterizes UE, can use peak power.

So, in initial transmission phase, it is necessary to determine suitable E-DPDCH initial power for UE, to ensure before the SG of network side equipment transmission is not received by, data can be also sent, and then improve resource utilization.

And due in such scheme, E-DCH Dedicated Physical Data Channel channels can be determined in UE sides）It is initial to send SG used, so UE load target of the transmitting not over network can be ensured, and reduce the processing load of network side equipment.
