UCI feedback mechanism on PUCCH/PUSCH defined in Section 10.1 of V12.4.0 (2014-12) can be reused more to utilize
The UCI of up to 32 CC of a group of UCI feedback unloading.Due to uplink/downlink (" UL/DL ") control signaling standard
Very little is influenced, which is that tool is promising.If the program is supported, transmitted when introducing multiple PUCCH/PUSCH
When UCI, the priority and power scaling of the PUCCH/PUSCH in multiple and different CC groups should be redefined.
In addition, supporting to be used for main plot group (" MCG ") and secondary cell group (" SCG ") in Rel-12 dual link (" DC ")
Double PUCCH transmission, and define the uplink power control scheme of both of which.However, if supporting multiple
PUCCH, double-strand connect in the solution reached can not be extended in the situation of CA enhancing.Because being propped up in DC scheme
Two schedulers are held, this allows to execute up-link power in the case where not from the scheduling information of other base stations
Control.However, still retaining a scheduler in CA enhancing, allow to carry out uplink function under better coordinate
Rate control.Therefore, it in multiple embodiments of the disclosure, is supported in CA enhancing multiple with UCI in multiple CC groups

Secondly, working as PPUCCH(i) priority of distribution power is equal to PPUCCH, m(i) priority of distribution power, and CC group m packet
When including main plot:
IfIt is then rightPower scaling is carried out, so that following formula obtains
To satisfaction:
WhereinIt is PPUCCH, m(i) linear value.If there is no PUCCH transmission in the subframe i on CC group m,
Then PPUCCH, m(i)=0.
Otherwise, ifThen UE comes one of in the following manner to sending power
It is allocated:
A. power scaling is carried out to the transmission power of all PUCCH transmission of different CC groups,
So that following formula is met:
Wherein v (i) is CC group mZoom factor, wherein 0≤v (i)≤1.If the son on CC group m

B. the PUCCH that transmission power hair is allocated to CC group is transmitted with predefined priority ranking, example is according to CC group ID
Sequence from low to high is first allocated to the PUCCH of the tool lower CC group of CC group ID, and if remaining power is inadequate,
Then abandon the PUCCH transmission of the higher CC group of CC group ID.
If UE is configured without SCG and if UE has carrying UCI's on the serving cell j on CC group m
PUSCH transmission, and the remaining serving cell of CC group m it is any in do not have to carry the PUSCH transmission of UCI, and total transmission of UE
Power will be more thanThen UE will be for not having UCI's in the subframe i in the serving cell in different CC groupsPower scaling is carried out, so that the condition of following formula is met:
If
Then
WhereinIt is PPUSCH, j, m(i) linear value,It is PPUSCH, c, m(i) linear value, wm(i)

According to the sequence of CC group ID from low to high, that is, it is first allocated to the PUSCH transmission of the lower CC group of CC group ID, and if remaining
Power it is inadequate, then abandon the PUSCH transmission of the higher CC group of CC group ID.
If UE is configured without SCG, and if UE exists simultaneously PUCCH transmission and serving cell j on CC group m
The PUSCH transmission of upper carrying UCI, and it is not useful in any remaining serving cell in addition to serving cell j on CC group m
To be more than in total transmission power of the PUSCH of UCI transmission, and UEThen UE is obtained according to the following formula

In above-mentioned situation, it is assumed that the PUSCH transmission of UCI is carried on the serving cell j of CC group m, and PUCCH is transmitted
Not on serving cell j, but a CC can be specified by base station to be carried.In addition, in one implementation, PUCCH
Transmission with the PUSCH can also carry out in the same cell of CC group m.
It should be noted that being configured without the above-mentioned various situations of SCG for UE, work as wm(i) when > 0, wm(i) value exists
It is identical between serving cell, but for certain serving cells, wm(i) value may be zero；As v (i) > 0, v (i) value exists
It is identical between CC group to support multiple PUCCH to transmit, but for certain CC groups, v (i) may be zero；As u (i) > 0, u (i)
Value be between CC group it is identical, to support the PUSCH transmission of carrying UCI, but for certain CC groups, u (i) can be zero.
Situation II: there are prioritizations between multiple CC groups
For example, in some systems, for the CC of unauthorized, the CC group including the CC is relative to the LTE CC with authorization
CC group for, priority is lower.For this initial situation with prioritization, the disclosure is suggested following
Power distribution priority and power scaling mechanism:
A) for the CC group with different priorities, according to preassigned priority from high to low come to CC group distribution function
Rate distributes power to CC group with high priority first, and if total transmission power of UE will be more than
Then it is contemplated that abandoning the uplink transmission of the L1/L2 control signaling and data of CC group with low priority.
In one embodiment, although there are the differentiation of priority between multiple CC groups, CC group in part therein may have
There is identical priority.At this point, but being also not enough to support CC group with low priority if remaining power is not equal to zero
All uplink transmission.At this point, can be considered as due to these parts CC group priority having the same without first grade differentiation
A kind of special case, therefore the uplink as aforementioned the L1/L2 control signaling for abandoning CC group with low priority and data
The concomitant regimen of road transmission plan, above for the power that the situation I of prioritization is not discussed between multiple CC groups point
These parts CC group can also be similarly applied even to priority and power scaling mechanism.
B) such as institute's presentation in situation I, it is assumed that the priority of L1/L2 control signaling (such as UCI) transmission of all CC groups
The data transmission being higher than in any CC group.If total transmission power of UE is more thanThen first according to institute in situation I
UE is sent power distribution to carrying UCI's by the power distribution priority between CC group and power scaling mechanism discussed
PUCCH/PUSCH transmission.If there is also remaining transmission power, according to the assigned priorities of different CC groups sequence come to CC
Sub-data transmission in group, which is matched, sends power, rather than with identical zoom factor to all CC as discussed in situation I
All data transmission in group carries out power scaling operation.In one embodiment, if remaining transmission underpower is to prop up
All data transmission in some priority is held, then for the power point of the data transmission of CC group priority having the same
Match, it still can be using with the power scaling discussed for situation I or according to the preparatory of multiple CC groups with equal priority
The priority ranking of definition come carry out data transmission PUSCH send power distribution.
