Detailed description of the invention

Strengthen situation as previously mentioned, for the CA with up to 32 CC, need into one The UCI feedback of step strengthens.In order to solve the problem that UCI feedback resources lacks, can be by many Individual CC is divided into different multiple CC groups, and for each CC group, in main plot (" PCell ")/secondary cell (" SCell ") one PUCCH of upper distribution.Without This CC is assembled and puts PUCCH, the most also support to feed back UCI on the PUSCH of specific carriers Feedback.In other words, for each CC group, current 3GPP TS36.213V12.4.0 (2014-12) the UCI feedback mechanism on the PUCCH/PUSCH defined in Section 10.1 is permissible It is reused utilizing the UCI of multiple groups of UCI feedback unloading up to 32 CC.Due to upper (" impact that UL/DL ") controls signaling standard is the least, this solution for line link/downlink Scheme is that tool is promising.If the program is supported, then multiple when introducing PUCCH/PUSCH when PUCCH/PUSCH transmits UCI, in multiple different CC groups Priority and power scaling should be redefined.

It addition, in Rel-12 dual link (" DC "), support for main plot group (" MCG ") Transmit with double PUCCH of secondary cell group (" SCG "), and define both of which Uplink power control scheme..But, if supporting multiple PUCCH, double-strand connects In the solution reached can not be extended in the situation that CA strengthens.Because Supporting two schedulers in DC scheme, this allows to not from the tune of other base stations Perform up-link power in the case of degree information to control.But, in CA strengthens, still Retaining a scheduler, it allows to carry out up-link power control under preferably coordinating System.Therefore, in multiple embodiments of the disclosure, strengthen at CA and support in multiple CC groups On have UCI multiple PUCCH/PUSCH transmission scene in, it is proposed that new power Distribution priority and power scaling (" scaling ") mechanism.

Fig. 1 is to schematically show carrying out in strengthening according to one aspect of the invention at CA The flow chart of method 100 that power controls, wherein CA strengthens and includes a main CC and extremely An auxiliary CC, and all CC less is divided into multiple CC group, and the plurality of CC group In at least two CC group include for UE transmission UCI PUCCH and PUSCH in At least one.

As shown in fig. 1, described method 100 starts from step S100, and in step S101 Place, if being not provided with prioritization between multiple CC group, then method 100 is according in advance The transmit power of UE is allocated by the distribution priority of fixed transmit power.As method Another branch of 100, at step S102, if being provided with excellent between multiple CC groups First level is distinguished, then method 100 is according to priority transmission merit to UE between multiple CC groups Rate is allocated.

Finally, method 100 terminates at step S103.Application way 100, it is possible to achieve Effective power during CA strengthens is distributed, and particularly exists multiple in multiple CC groups In the transmission situation of PUCCH/PUSCH.Will be detailed below how multiple CC groups it Between the distribution priority of transmit power is set and how to carry out power distribution according to priority.

Before the power describing the disclosure in detail distributes priority and power scaling mechanism, First various symbols and abbreviation to occurring in each inequality being described later on or formula is carried out Definition:

P_PUCCHI () is that the UE of the PUCCH transmission of configuration in subframe i on main plot sends merit Rate,

P_PUCCH,mI () is configuration in subframe i on the CC of CC group m in multiple CC group The UE transmit power of PUCCH,

P_PUSCH,j,m(i) be in subframe i in the Serving cell j in CC group m configuration have described The UE transmit power of the PUSCH transmission of UCI,

P_PUSCH,c,m(i), c ≠ j be in subframe i on the Serving cell c in CC group m configuration there is no institute State the UE transmit power of the PUSCH transmission of UCI.

Situation I: do not have prioritization between multiple CC groups

■ priority defines:

I. the distribution priority orders of predefined following UE transmit power in CA strengthens:

1)P_PUCCH(i) ＞ P_PUCCH,m(i) ＞ P_PUSCH,j,m(i) ＞ P_PUSCH,c,m(i),c≠j (1)

In the priority arrangement order of above formula (1), for the main plot or auxiliary of different CC groups Multiple PUCCH transmission on community, defines the transmission that the PUCCH on described main plot transmits The distribution priority of power is higher than the distribution priority of the PUCCH transmission of other secondary cells.

2)P_PUCCH(i),P_PUCCH,m(i) ＞ P_PUSCH,j,m(i) ＞ P_PUSCH,c,m(i),c≠j (2)

In the priority arrangement order of above formula (2), on described main plot and secondary cell The distribution priority of the transmit power of PUCCH transmission is identical.

Ii. different CC groups are carried to PUCCH or the PUSCH transmission of UCI, if Total transmit power of UE is by the maximum transmit power more than UEUnder then can passing through One of the two ways in face has the multiple of UCI to having equal priority The transmit power of PUCCH/PUSCH is allocated:

1) to having the transmission merit that equal priority carries the PUCCH/PUSCH of UCI Rate zooms in and out, and can guarantee with the power that the desired power of distribution ratio is lower The transmission of PUCCH/PUSCH.

2) power distribution is carried out according to a predefined prioritization.Such as, have PUCCH/PUSCH transmission in the CC group of relatively low CC group index (" ID ") will Obtain the priority of higher up-link power distribution.If it means that remaining Send underpower to support that the PUCCH/PUSCH with UCI of all different CC groups passes Time defeated, the CC group with higher CC group ID will have to be abandoned, and does not passes Defeated.

■ power scaling scene and operation:

$\underset{c}{\mathrm{\Σ}}{w}_m\left(i\right)\·{\hat{P}}_{\mathrm{PUSCH},c,m}\left(i\right)\≤({\hat{P}}_{\mathrm{CMAX}}\left(i\right)-{\hat{P}}_{\mathrm{PUCCH}}\left(i\right))---\left(3\right)$

WhereinIt is P_PUCCHThe linear value of (i),It is P_PUSCH,c,mThe linear value of (i),It it is the UE of configuration always maximum transmit power P in subframe i_CMAXLinear value, and w_m(i) It is the P of the Serving cell c of CC group m_PUSCH,c,mThe zoom factor of (i), wherein 0≤w (i)≤1, and c ≠ j. If not having PUCCH to transmit, then in subframe i

● if UE is configured without SCG, and during CA is strengthened multiple not With CC group, multiple PUCCH transmit and are arranged to main plot/secondary cell, and such as Really total transmit power of UE exceedesThen UE performs in CC group m In subframe i of Serving cell cPower scaling operation so that following formula In condition be met:

1) if

The most rightCarry out power scaling, so that following formula is met:

WhereinIt is P_PUCCH,mThe linear value of (i), and if subframe in CC group m I does not have PUCCH transmit, then P_PUCCH,m(i)=0.

Otherwise,

2) ifThen UE in the following manner it Transmit power is allocated by one:

A. the transmit power of the PUCCH in other CC groups in addition to main plot is contracted Put, so that following formula is met:

Wherein v (i) is CC group mZoom factor, and CC group m do not includes main Community.If not having PUCCH to transmit in subframe i of CC group m, then P_PUCCH,m(i)=0.

B. with predefined prioritization transmit power sent out and be allocated to different CC group PUCCH transmits, such as, according to CC group ID order from low to high, first divide The PUCCH of the CC group that dispensing CC group ID is relatively low, and if remaining power Not, then the PUCCH transmission of CC group ID higher CC group is abandoned.

Secondly, P is worked as_PUCCHI the priority of () distribution power is equal to P_PUCCH,mI () distributes the preferential of power Level, and when CC group m includes main plot:

IfThe most rightCarry out power scaling, so that Following formula is met:

WhereinIt is P_PUCCH,mThe linear value of (i).If in subframe i in CC group m PUCCH is not had to transmit, then P_PUCCH,m(i)=0.

Otherwise, ifThen UE comes one of in the following manner Transmit power is allocated:

A. the transmit power of all PUCCH transmission of different CC groups is carried out power scaling, So that following formula is met:

Wherein v (i) is CC group mZoom factor, wherein 0≤v (i)≤1.If Subframe i in CC group m does not have PUCCH to transmit, then P_PUCCH,m(i)=0.

B. with predefined prioritization transmit power sent out the PUCCH being allocated to CC group Transmission, example, according to CC group ID order from low to high, is i.e. first allocated to tool CC The PUCCH of the group relatively low CC group of ID, and if remaining power not, then Abandon the PUCCH transmission of CC group ID higher CC group.

● if if UE is configured without SCG and UE clothes in CC group m There is on business community j the PUSCH transmission of carrying UCI, and the residue of CC group m takes Business community any in do not carry the PUSCH transmission of UCI, and the total of UE sends out Power is sent to exceedThen UE is by for the Serving cell in different CC groups In subframe i in there is no UCI'sCarry out power scaling so that the bar of following formula Part is met:

If $\underset{m}{\mathrm{\Σ}}{\hat{P}}_{\mathrm{PUSCH},j,m}\left(i\right)\≤{\hat{P}}_{\mathrm{CMAX}}\left(i\right),$

Then $\underset{c\≠j}{\mathrm{\Σ}}{w}_m\left(i\right)\·{\hat{P}}_{\mathrm{PUSCH},c,m}\left(i\right)\≤({\hat{P}}_{\mathrm{CMAX}}\left(i\right)-\underset{m}{\mathrm{\Σ}}{\hat{P}}_{\mathrm{PUSCH},j,m}\left(i\right))---\left(8\right)$

WhereinIt is P_PUSCH,j,mThe linear value of (i),It is P_PUSCH,c,mThe linear value of (i), w_mI () isZoom factor.

IfTransmit power is entered one of in the following manner by UE Row distribution:

The most rightTransmit power carry out power scaling, so that following formula is met:

$\underset{m}{\mathrm{\Σ}}u\left(i\right){\hat{P}}_{\mathrm{PUSCH},j,m}\left(i\right)\≤{\hat{P}}_{\mathrm{CMAX}}\left(i\right)---\left(9\right)$

Wherein u (i) is CC group mZoom factor, wherein 0≤u (i)≤1.If Subframe i in CC group m do not has PUSCH transmission, then

B. with predefined prioritization transmit power sent out the carrying UCI being allocated to CC group PUSCH transmission, such as according to CC group ID order from low to high, first divide The PUSCH transmission of the CC group that dispensing CC group ID is relatively low, and if remaining merit Rate is inadequate, then abandon the PUSCH transmission of CC group ID higher CC group.

● if UE is configured without SCG, and if UE in CC group m with Time there is PUCCH transmission and the PUSCH transmission of Serving cell j upper carrying UCI, And in the arbitrarily residue Serving cell in addition to Serving cell j in CC group m not There is the PUSCH for UCI transmission, and total transmit power of UE will exceed Then UE obtains according to following formulaThat is:

If

Then

(10)

Otherwise,

If

Then transmit power is allocated one of in the following manner by UE:

A. between the PUSCH transmission of the carrying UCI of different CC groups, power scaling is carried out, So that the condition of following formula is met:

Wherein u (i) is CC group mZoom factor, wherein 0≤u (i)≤1.If The PUSCH transmission of UCI is not carried, then in subframe i of CC group m ${\hat{P}}_{\mathrm{PUSCH},j,m}\left(i\right)=0.$

B. with predefined prioritization transmit power sent out the carrying being allocated to CC group m The PUSCH transmission of UCI, such as according to CC group ID order from low to high, i.e. first First distribute to the PUSCH transmission of the relatively low CC group of CC group ID, and if remained Power inadequate, then abandon the PUSCH transmission of CC group ID higher CC group.

In above-mentioned situation, it is assumed that the PUSCH transmission of carrying UCI is at the clothes of CC group m On business community j, and PUCCH transmits not on Serving cell j, but can be by base station A CC is specified to carry.It addition, in one implementation, PUCCH and this PUSCH Transmission can also carry out in the same community of CC group m.

It should be noted that above-mentioned various situations UE being configured without to SCG, when w_mDuring (i) ＞ 0, w_mI the value of () is identical between Serving cell, but little for some service District, w_mI () value is probably zero；As v (i) ＞ 0, v (i) value is identical to support between CC group Multiple PUCCH transmit, but for some CC group, v (i) may be zero；As u (i) ＞ 0, u (i) Value is identical between CC group, to support the PUSCH transmission of carrying UCI, but for certain A little CC groups, u (i) can be zero.

Situation II: there is prioritization between multiple CC groups

Such as, in some systems, for undelegated CC, including the CC group of this CC For having the CC group of LTE CC of mandate, its priority is relatively low.For This situation initially with prioritization, the disclosure advises that following power distribution is preferential Level and power scaling mechanism:

A) for having the CC group of different priorities, according to preassigned priority from height To low, CC component is joined power, first distribute power to the CC with high priority Group, and if total transmit power of UE will exceedThen can consider to abandon to have The L1/L2 of the CC group of low priority controls signaling and the ul transmissions of data.

In one embodiment, although there is the differentiation of priority between multiple CC group, but wherein Part CC group be likely to be of identical priority.Now, if remaining power is not equal to Zero, but also it is not enough to support to have all ul transmissions of the CC group of low priority.This Time, owing to these part CC groups have identical priority, can be considered as not having first level to distinguish A class special case, therefore as the aforementioned L1/L2 abandoning there is the CC group of low priority Control the concomitant regimen of the ul transmissions scheme of signaling and data, above for multiple The power not having situation I of prioritization to be discussed between CC group distributes priority and power contracting The mechanism of putting can also be similarly applied even to these part CC groups.
