If UE is in present sub-frame i, at community c ' existence carrying UCI (Uplink Control Information, ascending control information) PUSCH transmission, and the PUSCH transmission not carrying UCI is there is in other Serving cells, and UE has exceeded the maximum transmission power of UE permission in total transmitting power of present sub-frame i, then when carrying out power reduction, UE preferentially should ensure that the through-put power of PUSCH carrying UCI does not reduce, and UE needs equal proportion to reduce in present sub-frame i each transmitting power not carrying the PUSCH of UCI with full UE maximum transmission power:

$\underset{c\≠c^{\′}}{\mathrm{\Σ}}w\left(i\right)g{\hat{P}}_{\mathrm{PUSCH},c}\left(i\right)\≤({\hat{P}}_{\mathrm{CMAX}}\left(i\right)-{\hat{P}}_{\mathrm{PUSCH},C^{\′}}\left(i\right));$

Wherein, for carrying the linear thresholding of the transmitting power of the PUSCH of UCI, w (i) is each PUSCH power reduction factor do not carried on the Serving cell c of UCI, 0≤w (i)≤1.When all PUSCH power not carrying UCI is all reduced to 0, total transmitting power of UE is also above maximum permission transmitting power, then reduce power to the PUSCH of carrying UCI further.

If UE is in present sub-frame i, there is PUCCH simultaneously, carry the PUSCH transmission of UCI and do not carry the PUSCH transmission of UCI, and total transmitting power of UE has exceeded maximum permission transmitting power, then UE preferentially should ensure the through-put power of PUCCH, secondly ensure the through-put power of the PUSCH of carrying UCI, and equal proportion reduces PUSCH transmitting power on each community c to meet UE maximum transmission power:

${\hat{P}}_{\mathrm{PUSCH},j}\left(i\right)=\min ({\hat{P}}_{\mathrm{PUSCH},i}\left(i\right),({\hat{P}}_{\mathrm{CMAX}}\left(i\right)-{\hat{P}}_{\mathrm{PUCCH}}\left(i\right)))$ With $\underset{c\≠j}{\mathrm{\Σ}}w\left(i\right)\·{\hat{P}}_{\mathrm{PUSCH},c}\left(i\right)\≤({\hat{P}}_{\mathrm{CMAX}}\left(i\right)-{\hat{P}}_{\mathrm{PUCCH}}\left(i\right)-{\hat{P}}_{\mathrm{PUSCH},j}\left(i\right));$

For the SRS that community multiple in same subframe is transmitted simultaneously, if total transmitting power of UE has exceeded maximum permission transmitting power, then equal proportion power reduction is carried out to meet UE maximum transmission power to the SRS on each community:

$\underset{c}{\mathrm{\Σ}}w\left(i\right)\·{\hat{P}}_{\mathrm{SRS},c}\left(i\right)\≤{\hat{P}}_{\mathrm{CMAX}}\left(i\right);$

Wherein for P _{sRS, c}i the linear thresholding of (), w (i) is the SRS power reduction factor on each community c, 0≤w (i)≤1.

In LTE-ARel-11, support that multiple member carriers of the terminal polymerization of LTE-A CA technology may belong to different frequency bands, and ownership frequency band spacing also may be larger, be therefore in different frequency bands be referred to as different frequency bands under carrier aggregation, i.e. inter-band CA.As shown in Figure 2, terminal polymerization Liao Sange community: Cell1, Cell2 and Cell3, wherein Cell1 and Cell2 is in frequency band Band1, and Cell3 is in Band2.Be in the community of different band (frequency band), its transmission characteristic differs greatly, if therefore a terminal can be polymerized multiple Band, and different B and can support that different TDD UL/DL is configured to avoid facing interference frequently, so in general terminal can use different transceivers for different B and.

Below in conjunction with Figure of description, the embodiment of the present invention is described in further detail.

In lte-a system, when the carrier wave of UE polymerization/activation belongs to different frequency bands (band), if the transmitting power sum being in the up channel on all carrier waves of identical, different band all has exceeded the permission maximum transmission power of UE, UE need carry out power reduction, be no more than the maximum transmission power of UE permission with the transmitting power sum meeting the up channel on all carrier waves being in identical, different band, concrete power reduction method is see Fig. 3.

As shown in Figure 3, the method for embodiment of the present invention uplink power control comprises the following steps:

Step 301, subscriber equipment, according to the maximum transmit power value of each carrier wave and power control parameter value corresponding to each carrier wave, determine the transmission power level of the up channel on each carrier wave;

Whether the transmission power level sum of each up channel that step 302, subscriber equipment judge in all frequency bands is greater than the permission maximum transmit power value of subscriber equipment;

Step 303, when the transmission power level sum of each up channel that subscriber equipment judges in all frequency bands is greater than the permission maximum transmit power value of subscriber equipment, carry out power reduction according to the permission maximum transmit power value of subscriber equipment and power reduction scalefactor value corresponding to each frequency band, make the transmission power level sum of each up channel in all frequency bands after power reduction be not more than the permission maximum transmit power value of subscriber equipment.

Preferably, when the transmission power level sum of each up channel that subscriber equipment judges in all frequency bands is not more than the permission maximum transmit power value of subscriber equipment, subscriber equipment sends up channel according to the transmission power level of the up channel of each carrier wave in each frequency band determined.

In force, the power reduction scalefactor value that each frequency band is corresponding is that subscriber equipment and network side are made an appointment, or network side is by high-level signaling or PDCCH (Physical Downlink Control Channel, Physical Downlink Control Channel) signal deployment to subscriber equipment;

Wherein, the power reduction scalefactor value that each frequency band is corresponding is not more than 1 and is not less than 0.

Preferably, high-level signaling includes but not limited at least one in following signaling:

RRC (Radio Resource Control, wireless heterogeneous networks) signaling and MAC (Medium Access Control, medium education) signaling.

Preferably, power reduction scalefactor value can be determined based on the characteristic of different band, the transmission information type, business etc. of such as frequency position, bandwidth, channel status, configuration.

Wherein, the power reduction scalefactor value that different frequency bands is corresponding is identical or different;

When the power reduction scalefactor value of different frequency bands is identical, power reduction proportionality coefficient can not configure or not arrange.

Preferably, subscriber equipment is according to the permission maximum transmit power value of subscriber equipment and power reduction scalefactor value corresponding to each frequency band, successively power reduction is carried out to up channel according to channel priority order from low to high or from high to low, make the transmission power level sum of each up channel in all frequency bands after power reduction be not more than the permission maximum transmit power value of subscriber equipment.

Preferably, the priority of up channel is:

There is no PRACH (Physical Random Access Channel, Physical Random Access Channel) when transmitting, PUCCH (Physical Uplink Control Channel, Physical Uplink Control Channel) priority > carry UCI (Uplink Control Information, ascending control information) the priority > of PUSCH (Physical Uplink Shared Channel, Physical Uplink Shared Channel) do not carry the priority of the PUSCH of UCI;

When there being PRACH to transmit, the priority > of the PUSCH of the priority > carrying UCI of the priority > PRACH of PUCCH does not carry the priority of the PUSCH of UCI, or the priority > of the PUSCH of the priority > carrying UCI of the priority > PUCCH of PRACH does not carry the priority of the PUSCH of UCI.Preferably, other priority level initializing modes are not got rid of.

Wherein, subscriber equipment can not carry out power reduction according to channel priority, also can carry out power reduction according to channel priority.

Power reduction is not carried out: step 403, when the transmission power level sum of each up channel that subscriber equipment judges in all frequency bands is greater than the permission maximum transmit power value of subscriber equipment according to channel priority, equal proportion reduction is carried out to the transmission power level of each up channel in all frequency bands, makes the transmission power level sum of each up channel in all frequency bands after power reduction be not more than the permission maximum transmit power value of subscriber equipment.

Carry out power reduction according to channel priority: step 403, subscriber equipment carry out equal proportion power reduction to the channel with same channel priority in all frequency bands, make the transmission power level sum of each up channel in all frequency bands after power reduction be not more than the permission maximum transmit power value of subscriber equipment.

If carry out power reduction according to channel priority, specifically comprise:

When the power reduction proportionality coefficient that each band is corresponding is identical: based on permission maximum transmission power and the channel priority of UE, equal proportion power reduction is carried out to the channel with same channel priority in all band, is no more than with the transmitting power sum of the up channel on all carrier waves in all band after meeting power reduction the maximum transmission power that UE allows;

When carrying out power reduction based on channel priority, preferential reduction has the transmitting power of the channel of lower channel priority;

Channel priority during power division in all band is the PUSCH that PUSCH > that PUCCH > carries UCI does not carry UCI, namely the transmitting power of preferential guarantee PUCCH does not reduce, in available launch power beyond the maximum transmission power removing PUCCH transmitting power that UE allows, the PUSCH power of preferential guarantee carrying UCI does not reduce, reduce the power that all the other do not carry the PUSCH of UCI, until total transmitting power sum of all channels of UE is no more than the permission maximum transmission power of UE;

Or, if there is PRACH transmission, the priority of the power division in all band is the PUSCH that PUSCH > that PUCCH > PRACH > carries UCI does not carry UCI, namely the transmitting power of preferential guarantee PUCCH does not reduce, in available launch power beyond the maximum transmission power removing PUCCH transmitting power that UE allows, the transmitting power of preferential guarantee PRACH does not reduce, in available launch power beyond maximum transmission power removing PUCCH and the PRACH transmitting power that UE allows, the PUSCH power of preferential guarantee carrying UCI does not reduce, reduce the power that all the other do not carry the PUSCH of UCI, until total transmitting power sum of all channels of UE is no more than the permission maximum transmission power of UE, or the PUSCH > of PRACH > PUCCH > carrying UCI does not carry the PUSCH of UCI, namely the transmitting power of preferential guarantee PRACH does not reduce, in available launch power beyond the maximum transmission power removing PRACH transmitting power that UE allows, the transmitting power of preferential guarantee PUCCH does not reduce, in available launch power beyond maximum transmission power removing PRACH and the PUCCH transmitting power that UE allows, the PUSCH power of preferential guarantee carrying UCI does not reduce, reduce the power that all the other do not carry the PUSCH of UCI, until total transmitting power sum of all channels of UE is no more than the permission maximum transmission power of UE.

UE, first according to formula (1), calculates the PUCCH transmitting power P in band1 and band2 respectively according to b=1 and b=2 _{pUCCH, 1}(i) and P _{pUCCH, 2}(i), wherein b is band numbering;

Then the PUSCH transmitting power P not having PUCCH simultaneously to transmit at a carrier wave is calculated in band1 and band2 according to formula (2) _{pUSCH, 2}(i), P _{pUSCH, 4}(i) and P _{pUSCH, 5}(i);

The PUSCH transmitting power P that simultaneously there is PUCCH on a carrier wave in band2 is calculated according to formula (3) _{pUSCH, 3}(i);

Or, if there is PRACH transmission, channel priority during power division in each band is the PUSCH that PUSCH > that PUCCH > PRACH > carries UCI does not carry UCI, namely the transmitting power of preferential guarantee PUCCH does not reduce, in available launch power beyond total transmitting power removing PUCCH transmitting power of the current band after power reduction, the transmitting power of preferential guarantee PRACH does not reduce, in available launch power beyond total transmitting power removing PUCCH and PRACH transmitting power of the current band after power reduction, the PUSCH power of preferential guarantee carrying UCI does not reduce, reduce the power that all the other do not carry the PUSCH of UCI, until total transmitting power sum of all channels of UE is no more than the permission maximum transmission power of UE, or the PUSCH > of PRACH > PUCCH > carrying UCI does not carry the PUSCH of UCI, namely the transmitting power of preferential guarantee PRACH does not reduce, in available launch power beyond total transmitting power removing PRACH transmitting power of the current band after power reduction, the transmitting power of preferential guarantee PUCCH does not reduce, in available launch power beyond total transmitting power removing PRACH and PUCCH transmitting power of the current band after power reduction, the PUSCH power of preferential guarantee carrying UCI does not reduce, reduce the power that all the other do not carry the PUSCH of UCI, until total transmitting power sum of all channels of UE is no more than the permission maximum transmission power of UE.

Such as, in Fig. 8, carrier wave 1 in UE polymerization band1 and carrier wave 2, and carrier wave 3, carrier wave 4 and the carrier wave 5 in band2 carries out uplink, each band is configured with a particular carrier, and as the carrier wave transmitting PUCCH, (namely each band is configured with an expansion carrier wave E-cell, be similar to the Pcell in Rel-10), the concrete behavior of UE is as follows:

UE, first according to formula (1), calculates the PUCCH transmitting power P in band1 and band2 respectively according to b=1 and b=2 _{pUCCH, 1}(i) and P _{pUCCH, 2}(i), wherein b is band numbering;

Then the PUSCH transmitting power P not having PUCCH simultaneously to transmit at a carrier wave is calculated in band1 and band2 according to formula (2) _{pUSCH, 2}(i), P _{pUSCH, 4}(i) and P _{pUSCH, 5}(i);

The PUSCH transmitting power P that simultaneously there is PUCCH on a carrier wave in band2 is calculated according to formula (3) _{pUSCH, 3}(i);

UE judges the maximum transmission power whether the transmitting power sum of the up channel on all carrier waves in all band allows more than UE further:

Work as judgement ${\hat{P}}_{\mathrm{PUCCH},1}\left(i\right)+{\hat{P}}_{\mathrm{PUSCH},2}\left(i\right)+{\hat{P}}_{\mathrm{PUCCH},2}\left(i\right)+{\hat{P}}_{\mathrm{PUSCH},3}\left(i\right)+{\hat{P}}_{\mathrm{PUSCH},4}\left(i\right)+{\hat{P}}_{\mathrm{PUSCH},5}\left(i\right)>{\hat{P}}_{\mathrm{CMAX}}\left(i\right)$ Time, need to carry out power reduction, suppose to carry out power reduction based on channel priority, specifically comprise:

First the current total transmitting power of each band is calculated according to formula (13), namely with wherein b is band numbering, and carries out equal proportion power reduction according to total transmitting power of formula (14) to each band, is no more than the maximum transmission power of UE permission with the total transmitting power sum meeting the multiple band after power reduction; In formula (14), w (i) is power reducing coefficient, uses identical value to total transmitting power of all band;

${\hat{P}}_{T,b}\left(i\right)=\underset{b}{\mathrm{\Σ}}({\hat{P}}_{\mathrm{PUCCH},b}\left(i\right)+{\hat{P}}_{\mathrm{PUSCH},c,b}\left(i\right))$ Formula (13);

$\underset{b}{\mathrm{\Σ}}w\left(i\right)\·{{\hat{P}}_{T,b}}^{\′}\left(i\right)\≤{\hat{P}}_{\mathrm{CMAX}}\left(i\right)$ Formula (14);

Then UE is based on the total transmitting power after each band power reduction and channel priority, in each band, the transmitting power of preferential guarantee PUCCH does not reduce, the PUSCH that residue UE power preferentially meets the carrying UCI in this band is sent, and same ratio power is reduced to the channel (if do not carried the PUSCH of UCI) with identical low priority in this band, that is:

If wherein b is band numbering, for band 1, j=2, for band2, j=3, the transmitting power namely carrying the PUSCH of UCI exceeded this band gross power reduce after dump power, then for the transmitting power of the PUSCH of the carrying UCI after each band internal power reduction, UE sends each up channel according to the transmitting power after power reduction, and determines the PUSCH (namely the transmitting power of these PUSCH is reduced to 0) not carrying UCI that do not send in present sub-frame in this band;

If wherein b is band numbering, for band1, j=2, for band2, the transmitting power of j=3, the PUSCH of the carrying UCI namely in this band do not exceed this band gross power reduce after dump power, do not need to carry out power reduction to the PUSCH of carrying UCI, according to formula (15), equal proportion power reduction is carried out to the PUSCH not carrying UCI further, with total transmitting power of channel in this band after meeting power reduction be no more than this band gross power reduce after total transmitting power; In formula (15), w _bi there is in () band b the power reducing coefficient of the channel of equal priority, identical to all PUSCH values in same band, and specific its w (i) of PUSCH can be 0 (namely power can be reduced to 0); UE sends each up channel according to the transmitting power after power reduction;

Wherein, ${\hat{P}}_{\mathrm{PUSCH},j,b}\left(i\right)=\min ({\hat{P}}_{\mathrm{PUSCH},j,b}\left(i\right),({{\hat{P}}_{T,b}}^{\′}\left(i\right)-{\hat{P}}_{\mathrm{PUCCH},b}\left(i\right))).$

Work as judgement ${\hat{P}}_{\mathrm{PUCCH},1}\left(i\right)+{\hat{P}}_{\mathrm{PUSCH},2}\left(i\right)+{\hat{P}}_{\mathrm{PUCCH},2}\left(i\right)+{\hat{P}}_{\mathrm{PUSCH},3}\left(i\right)+{\hat{P}}_{\mathrm{PUSCH},4}\left(i\right)+{\hat{P}}_{\mathrm{PUSCH},5}\left(i\right)\≤{\hat{P}}_{\mathrm{CMAX}}\left(i\right)$ Time, can directly send according to the rated output on each carrier wave in multiple band.

It should be noted that, in above-described embodiment, when there is not PUCCH transmission, when there is not the PUSCH transmission of carrying UCI, said process is applicable equally; In said process for P _xthe linear thresholding of (i).

Again such as, in Fig. 9, UE is polymerized carrier wave 1, carrier wave 2 and carrier wave 3 in band1, and carrier wave 4 in band2 and carrier wave 5 carry out uplink, and only there is a Pcell in multiple band, to transmit the concrete behavior of PUCCH, UE as follows:

First UE calculates the PUCCH transmitting power P in band1 according to formula (1) b=1 _pUCCH(i), wherein b is band numbering; The PUSCH transmitting power P in band1 and band2 on corresponding carrier wave is calculated according to formula (2) _{pUSCH, 2}(i), P _{pUSCH, 3}(i), P _{pUSCH, 4}(i) and P _{pUSCH, 5}(i);

UE judges the maximum transmit power value whether the transmission power level sum of the up channel on all carrier waves in all band allows more than UE further:

Work as judgement ${\hat{P}}_{\mathrm{PUCCH}}\left(i\right)+{\hat{P}}_{\mathrm{PUSCH},2}\left(i\right)+{\hat{P}}_{\mathrm{PUSCH},3}\left(i\right)+{\hat{P}}_{\mathrm{PUSCH},4}\left(i\right)+{\hat{P}}_{\mathrm{PUSCH},5}\left(i\right)>{\hat{P}}_{\mathrm{MAX}}\left(i\right)$ Time, need to carry out power reduction, suppose to carry out power reduction based on channel priority, specifically comprise:

Then UE is based on the total transmitting power after each band power reduction and channel priority, in each band, the transmitting power of preferential guarantee PUCCH does not reduce, the PUSCH that residue UE power preferentially meets the carrying UCI in this band is sent, and same ratio power is reduced to the channel (if do not carried the PUSCH of UCI) with identical low priority in this band, that is:

For band1, if wherein b=1 is band numbering, j=2, the transmitting power namely carrying the PUSCH of UCI exceeded this band gross power reduce after dump power, then for the transmitting power of the PUSCH of the carrying UCI after each band internal power reduction, UE sends each up channel according to the transmitting power after power reduction, and determines the PUSCH (namely the transmitting power of these PUSCH is reduced to 0) not carrying UCI that do not send in present sub-frame in this band;

For band1, if wherein b=1 is band numbering, j=2, the transmitting power of the PUSCH of the carrying UCI namely in this band do not exceed this band gross power reduce after dump power, do not need to carry out power reduction to the PUSCH of carrying UCI, according to formula (15), equal proportion power reduction is carried out to the PUSCH not carrying UCI further, with total transmitting power of channel in this band after meeting power reduction be no more than this band gross power reduce after total transmitting power; In formula (15), w _bi there is in () band b the power reducing coefficient of the channel of equal priority, identical to all PUSCH values in same band, and specific its w (i) of PUSCH can be 0 (namely power can be reduced to 0); UE sends each up channel according to the transmitting power after power reduction;

For band2, if wherein b=2 is band numbering, then directly send the PUSCH in this band according to original calculation power; If then based on the total transmitting power after this band gross power reduces, equal proportion power reduction is carried out to the PUSCH in this band according to formula (16), with total transmitting power of channel in this band after meeting power reduction be no more than this band gross power reduce after total transmitting power; In formula (16), w _bi there is in () band b the power reducing coefficient of the channel of equal priority, identical to all PUSCH values in same band, and specific its w (i) of PUSCH can be 0 (namely power can be reduced to 0); UE sends each up channel according to the transmitting power after power reduction;

It should be noted that, in above-described embodiment, when there is not PUCCH transmission, when there is not the PUSCH transmission of carrying UCI, said process is applicable equally; In said process for P _xthe linear thresholding of (i).

Carrying out the under powered example of equal proportion in above-mentioned Fig. 8 and Fig. 9 for not carrying out under powered scheme based on channel priority, not needing the priority distinguishing different channels, power being reduced to all channels simultaneously, does not repeat them here.

Again such as, Tu10Zhong, UE are polymerized carrier wave 1 in band1 and carrier wave 2, and carrier wave 3 in band2 and carrier wave 4 carry out uplink, and the concrete behavior of UE is as follows:

First UE calculates SRS (detection reference signal) the transmitting power P in band1 and band2 on each carrier wave according to formula (7) _{sRS, 1}, P _{sRS, 2}, P _{sRS, 3}and P _{sRS, 4};

UE judges the maximum transmission power whether the SRS transmitting power sum on all carrier waves in all band allows more than UE further:

Namely judgement is worked as ${\hat{P}}_{\mathrm{SRS},1}\left(i\right)+{\hat{P}}_{\mathrm{SRS},2}\left(i\right)+{\hat{P}}_{\mathrm{SRS},3}\left(i\right)+{\hat{P}}_{\mathrm{SRS},4}\left(i\right)>{\hat{P}}_{\mathrm{CMAX}}\left(i\right)$ Time, need to carry out power reduction, owing to only having a kind of signal in Figure 10, so do not carry out power reduction based on channel priority here, specifically comprise:

First the current total transmitting power of each band is calculated according to formula (17) with wherein b is band numbering, and carries out equal proportion power reduction according to total transmitting power of formula (14) to each band, is no more than the maximum transmission power of UE permission with the total transmitting power sum meeting the multiple band after power reduction; In formula (14), w (i) is power reducing coefficient, uses identical value to total transmitting power of all band;

${\hat{P}}_{T,b}\left(i\right)=\underset{b}{\mathrm{\Σ}}\left({\hat{P}}_{\mathrm{SRS},c,b}\left(i\right)\right)$ Formula (17);

Then UE is based on the total transmitting power after each band power reduction, the total transmitting power of SRS judging in each band whether exceed this band gross power reduce after total transmitting power, if that is: wherein b is band numbering, then directly send the SRS in this band according to original calculation power; If then based on the total transmitting power after this band gross power reduces, equal proportion power reduction is carried out to the SRS in this band according to formula (18), with total transmitting power of channel in this band after meeting power reduction be no more than this band gross power reduce after total transmitting power; In formula (18), w _bi the power reducing coefficient of SRS in () band b is identical to all SRS values in same band; UE sends each SRS according to the transmitting power after power reduction;

$\underset{c}{\mathrm{\Σ}}{w}_b\left(i\right)\·{\hat{P}}_{\mathrm{SRS},c,b}\left(i\right)\≤{{\hat{P}}_{T,b}}^{\′}\left(i\right)$ Formula (18).

Work as judgement ${\hat{P}}_{\mathrm{SRS},1}\left(i\right)+{\hat{P}}_{\mathrm{SRS},2}\left(i\right)+{\hat{P}}_{\mathrm{SRS},3}\left(i\right)+{\hat{P}}_{\mathrm{SRS},4}\left(i\right)\≤{\hat{P}}_{\mathrm{CMAX}}\left(i\right)$ Time, can directly send according to the SRS rated output on each carrier wave in multiple band;

It should be noted that, when the SRS in the present embodiment replaces with PUSCH or PUCCH or PRACH channel, applicable equally, be namely equivalent in not carrying out under powered scheme based on channel priority; In said process for P _xthe linear thresholding of (i).

As shown in Figure 7, the ascending power control method of embodiment of the present invention the second reduction different proportion comprises the following steps:

Step 701, subscriber equipment, according to the maximum transmit power value of each carrier wave and power control parameter value corresponding to each carrier wave, determine the transmission power level of the up channel on each carrier wave;

Whether the transmission power level sum of each up channel that step 702, subscriber equipment judge in all frequency bands is greater than the permission maximum transmit power value of subscriber equipment;

Wherein, subscriber equipment can not carry out power reduction according to channel priority, also can carry out power reduction according to channel priority.

Do not carry out power reduction according to channel priority: the power reduction proportionality coefficient that step 703, subscriber equipment are corresponding according to this frequency band to total transmission power level of each frequency band carries out power reduction, make total transmission power level sum of each frequency band after power reduction be not more than the permission maximum transmit power value of subscriber equipment; For each frequency band, subscriber equipment is based on total transmission power level of this frequency band after power reduction, judge whether the transmission power level sum of each up channel in this frequency band is greater than total transmission power level of this frequency band, if be greater than, then equal proportion power reduction is carried out to each up channel in this frequency band, the transmission power level sum of each up channel after making power reduction in this frequency band is not more than total transmission power level of this frequency band, if be not more than, then do not change the transmission power level of each up channel in this frequency band.

If carry out power reduction according to channel priority, specifically comprise:

When the power reduction proportionality coefficient that each band is corresponding is different: the maximum transmission power allowed based on UE, the power reduction proportionality coefficient corresponding according to band to the current total transmission power of each band carries out power reduction, the maximum transmission power that UE allows is no more than with the total transmitting power sum after meeting each band power reduction, and according to the total transmitting power after each band power reduction and the channel priority in each band, power is reduced to the channel equal proportion in same band with same channel priority, with the transmitting power sum of the up channel on all carrier waves in this band after meeting power reduction be no more than the total transmitting power of this band reduce after the total transmitting power of band,

Preferably, under powered method is carried out based on the power reduction proportionality coefficient that frequency band is corresponding in above-mentioned steps 703, when the power reduction proportionality coefficient that each band is corresponding is identical, for equal proportion power reduction, can not configure the power reduction proportionality coefficient that each band is corresponding, it is identical to all band that this proportionality coefficient is arranged in UE and base station; When power reduction proportionality coefficient corresponding to each band is different, be non-equal proportion power reduction, power reducing coefficient is make an appointment in UE and base station, or high-level signaling or PDCCH signal deployment are passed through to UE's in base station.

When carrying out power reduction based on channel priority, preferential reduction has the transmitting power of the channel of lower channel priority;

Channel priority during power division in each band is the PUSCH that PUSCH > that PUCCH > carries UCI does not carry UCI, namely the transmitting power of preferential guarantee PUCCH does not reduce, in available launch power beyond total transmitting power removing PUCCH transmitting power of the current band after power reduction, the PUSCH power of preferential guarantee carrying UCI does not reduce, reduce the power that all the other do not carry the PUSCH of UCI, until total transmitting power sum of all channels of UE is no more than the permission maximum transmission power of UE;

Or, if there is PRACH transmission, channel priority during power division in each band is the PUSCH that PUSCH > that PUCCH > PRACH > carries UCI does not carry UCI, namely the transmitting power of preferential guarantee PUCCH does not reduce, in available launch power beyond total transmitting power removing PUCCH transmitting power of the current band after power reduction, the transmitting power of preferential guarantee PRACH does not reduce, in available launch power beyond total transmitting power removing PUCCH and PRACH transmitting power of the current band after power reduction, the PUSCH power of preferential guarantee carrying UCI does not reduce, reduce the power that all the other do not carry the PUSCH of UCI, until total transmitting power sum of all channels of UE is no more than the permission maximum transmission power of UE, or the PUSCH > of PRACH > PUCCH > carrying UCI does not carry the PUSCH of UCI, namely the transmitting power of preferential guarantee PRACH does not reduce, in available launch power beyond total transmitting power removing PRACH transmitting power of the current band after power reduction, the transmitting power of preferential guarantee PUCCH does not reduce, in available launch power beyond total transmitting power removing PRACH and PUCCH transmitting power of the current band after power reduction, the PUSCH power of preferential guarantee carrying UCI does not reduce, reduce the power that all the other do not carry the PUSCH of UCI, until total transmitting power sum of all channels of UE is no more than the permission maximum transmission power of UE.

Such as, in Fig. 8, carrier wave 1 in UE polymerization band1 and carrier wave 2, and carrier wave 3, carrier wave 4 and the carrier wave 5 in band2 carries out uplink, each band is configured with a particular carrier, and as the carrier wave transmitting PUCCH, (namely each band is configured with an expansion carrier wave E-cell, be similar to the Pcell in Rel-10), the concrete behavior of UE is as follows:

UE, first according to formula (1), calculates the PUCCH transmitting power P in band1 and band2 respectively according to b=1 and b=2 _{pUCCH, 1}(i) and P _{pUCCH, 2}(i), wherein b is band numbering;

Then the PUSCH transmitting power P not having PUCCH simultaneously to transmit at a carrier wave is calculated in band1 and band2 according to formula (2) _{pUSCH, 2}(i), P _{pUSCH, 4}(i) and P _{pUSCH, 5}(i);

The PUSCH transmitting power P that simultaneously there is PUCCH on a carrier wave in band2 is calculated according to formula (3) _{pUSCH, 3}(i);

UE judges the maximum transmission power whether the transmitting power sum of the up channel on all carrier waves in all band allows more than UE further:

Work as judgement ${\hat{P}}_{\mathrm{PUCCH},1}\left(i\right)+{\hat{P}}_{\mathrm{PUSCH},2}\left(i\right)+{\hat{P}}_{\mathrm{PUCCH},2}\left(i\right)+{\hat{P}}_{\mathrm{PUSCH},3}\left(i\right)+{\hat{P}}_{\mathrm{PUSCH},4}\left(i\right)+{\hat{P}}_{\mathrm{PUSCH},5}\left(i\right)>{\hat{P}}_{\mathrm{CMAX}}\left(i\right)$ Time, need to carry out power reduction, suppose to carry out power reduction based on channel priority, specifically comprise:

$\underset{b}{\mathrm{\Σ}}{w}_b\left(i\right)\·{{\hat{P}}_{T,b}}^{\′}\left(i\right)\≤{\hat{P}}_{\mathrm{CMAX}}\left(i\right)$ Formula (19);

Then UE is based on the total transmitting power after each band power reduction and channel priority, in each band, the transmitting power of preferential guarantee PUCCH does not reduce, the PUSCH that residue UE power preferentially meets the carrying UCI in this band is sent, and same ratio power is reduced to the channel (if do not carried the PUSCH of UCI) with identical low priority in this band, that is:

If wherein b is band numbering, for band 1, j=2, for band2, j=3, the transmitting power namely carrying the PUSCH of UCI exceeded this band gross power reduce after dump power, then for the transmitting power of the PUSCH of the carrying UCI after each band internal power reduction, UE sends each up channel according to the transmitting power after power reduction, and determines the PUSCH (namely the transmitting power of these PUSCH is reduced to 0) not carrying UCI that do not send in present sub-frame in this band;

If wherein b is band numbering, for band1, j=2, for band2, the transmitting power of j=3, the PUSCH of the carrying UCI namely in this band do not exceed this band gross power reduce after dump power, do not need to carry out power reduction to the PUSCH of carrying UCI, according to formula (15), equal proportion power reduction is carried out to the PUSCH not carrying UCI further, with total transmitting power of channel in this band after meeting power reduction be no more than this band gross power reduce after total transmitting power; In formula (15), w _bi there is in () band b the power reducing coefficient of the channel of equal priority, identical to all PUSCH values in same band, and specific its w (i) of PUSCH can be 0 (namely power can be reduced to 0); UE sends each up channel according to the transmitting power after power reduction;

Work as judgement ${\hat{P}}_{\mathrm{PUCCH},1}\left(i\right)+{\hat{P}}_{\mathrm{PUSCH},2}\left(i\right)+{\hat{P}}_{\mathrm{PUCCH},2}\left(i\right)+{\hat{P}}_{\mathrm{PUSCH},3}\left(i\right)+{\hat{P}}_{\mathrm{PUSCH},4}\left(i\right)+{\hat{P}}_{\mathrm{PUSCH},5}\left(i\right)\≤{\hat{P}}_{\mathrm{CMAX}}\left(i\right)$ Time, can directly send according to the rated output on each carrier wave in multiple band.

It should be noted that, in above-described embodiment, when there is not PUCCH transmission, when there is not the PUSCH transmission of carrying UCI, said process is applicable equally; In said process for P _xthe linear thresholding of (i).

Again such as, in Fig. 9, UE is polymerized carrier wave 1, carrier wave 2 and carrier wave 3 in band1, and carrier wave 4 in band2 and carrier wave 5 carry out uplink, and only there is a Pcell in multiple band, to transmit the concrete behavior of PUCCH, UE as follows:

UE judges the maximum transmit power value whether the transmission power level sum of the up channel on all carrier waves in all band allows more than UE further:

Work as judgement ${\hat{P}}_{\mathrm{PUCCH}}\left(i\right)+{\hat{P}}_{\mathrm{PUSCH},2}\left(i\right)+{\hat{P}}_{\mathrm{PUSCH},3}\left(i\right)+{\hat{P}}_{\mathrm{PUSCH},4}\left(i\right)+{\hat{P}}_{\mathrm{PUSCH},5}\left(i\right)>{\hat{P}}_{\mathrm{CMAX}}\left(i\right)$ Time, need to carry out power reduction, suppose to carry out power reduction based on channel priority, specifically comprise: first calculate the current total transmitting power of each band according to formula (13) with wherein b is band numbering, and carries out equal proportion power reduction according to total transmitting power of formula (19) to each band, is no more than the maximum transmission power of UE permission with the total transmitting power sum meeting the multiple band after power reduction; In formula (19), w _bi () is the specific power reducing coefficient of different band, by high-level signaling or PDCCH signal deployment, or make an appointment for UE and base station;

First the current total transmitting power of each band is calculated according to formula (17) with wherein b is band numbering, and carries out equal proportion power reduction according to total transmitting power of formula (19) to each band, is no more than the maximum transmission power of UE permission with the total transmitting power sum meeting the multiple band after power reduction; In formula (19), w _bi () is the specific power reducing coefficient of different band, by high-level signaling or PDCCH signal deployment, or make an appointment for UE and base station.

Then UE is based on the total transmitting power after each band power reduction, the total transmitting power of SRS judging in each band whether exceed this band gross power reduce after total transmitting power, that is:

If wherein b is band numbering, then directly send the SRS in this band according to original calculation power; If then based on the total transmitting power after this band gross power reduces, equal proportion power reduction is carried out to the SRS in this band according to formula (18), with total transmitting power of channel in this band after meeting power reduction be no more than this band gross power reduce after total transmitting power; In formula (18), w _bi the power reducing coefficient of SRS in () band b is identical to all SRS values in same band; UE sends each SRS according to the transmitting power after power reduction.

Work as judgement ${\hat{P}}_{\mathrm{SRS},1}\left(i\right)+{\hat{P}}_{\mathrm{SRS},2}\left(i\right)+{\hat{P}}_{\mathrm{SRS},3}\left(i\right)+{\hat{P}}_{\mathrm{SRS},4}\left(i\right)\≤{\hat{P}}_{\mathrm{CMAX}}\left(i\right)$ Time, can directly send according to the SRS rated output on each carrier wave in multiple band;

It should be noted that, when the SRS in the present embodiment replaces with PUSCH or PUCCH or PRACH channel, applicable equally, be namely equivalent in not carrying out under powered scheme based on channel priority; In said process for P _xthe linear thresholding of (i).
