Wherein, first processing module 210 is selected an E-TFC group in all E-TFC groups of a carrier set, and the E-TFC group of selection need satisfy following condition:

1、

\underset{i}{Σ} P_{E - PUCH, i} \leq P_{\max} .

It is the transmitting power sum of each E-TFC correspondence in the E-TFC group; P _MaxIt is the user terminal maximum transmission power.

2,

Greater than threshold value,

It is the transmitted data amount sum of each E-TFC correspondence in the E-TFC group.

Further, can also increase a condition 3:

3, the transmitting power of each E-TFC correspondence is not more than single carrier and allows maximum transmission power in the E-TFC group.

Preferable, first processing module 210 is from all E-TFC groups of same carrier set correspondence, determine that the transmitting power sum of E-TFC correspondence in the same E-TFC group is not more than the maximum transmission power of user terminal, and the transmitted data amount sum of E-TFC correspondence (increases condition 3 if desired greater than all E-TFC groups of threshold value, then continue screening more once), an E-TFC group of the transmitted data amount sum maximum of selection E-TFC correspondence from all E-TFC groups of determining.

Concrete, first processing module 210 is selected an E-TFC group of transmitted data amount sum maximum from all E-TFC groups that satisfy above-mentioned two conditions.

In specific implementation process, if, then from all E-TFC groups that satisfy first condition, select an E-TFC group of transmitted data amount sum maximum not greater than the E-TFC group (perhaps not having setting threshold) of threshold value.

Concrete, for the situation of having only a carrier wave in the carrier set (such as three carrier waves among Fig. 2 B), because this carrier wave does not need and other allocation of carriers transmitting powers on the mandate time slot of this carrier set correspondence, all can adopt the mode of single carrier E-TFC to determine an available E-TFC for this carrier wave, and the E-TFC that uses in this carrier set as this carrier wave of the available E-TFC that will select.

Wherein, the embodiment of the invention selects the device of E-TFC can further include: E-TFC determination module 40.

E-TFC determination module 40 is used for after set determination module 10 is determined at least one carrier set, and first selects module 20 to select before the available E-TFC of each carrier wave, determines to comprise the available E-TFC of each carrier wave in the carrier set of a plurality of carrier waves.

E-TFC determination module 40 has multiple mode can determine the available E-TFC of each carrier wave, enumerates two kinds below:

Mode one, employing Formula, wherein

Be the β value of the code check correspondence of E-TFC, PRRI is an authorization power.

That is to say, from each carrier set that comprises a plurality of carrier waves, select the β value of the code check correspondence of E-TFC to be not more than the E-TFC of authorization power among all E-TFC of each carrier wave, with the E-TFC of selection available E-TFC as the carrier wave of correspondence.

Mode two, employing

Formula and

That is to say, from each carrier set that comprises a plurality of carrier waves, select the β value of the code check correspondence of E-TFC to be not more than after the E-TFC of authorization power among all E-TFC of each carrier wave, from the E-TFC that selects, select the transmitting power of E-TFC correspondence to be not more than the E-TFC that maximum transmission power and/or single carrier allow maximum transmission power once more.

Mode one is only used

Can simplify the calculating of each judgement, but the scope of available E-TFC is bigger, the number of times of subsequent calculations is more; Mode two is used formula

With

The combination scope that can dwindle available E-TFC as Rule of judgment, but the amount of calculation that single is judged can be more.

In specific implementation process, can select different modes as required.

Need to prove that the embodiment of the invention is not limited to above-mentioned two kinds of schemes, other can determine that the available E-TFC of each carrier wave uses the embodiment of the invention.

In specific implementation process, can the scope of all E-TFC not selected yet, determine available E-TFC, but with all E-TFC all as available E-TFC.

Wherein, the embodiment of the invention selects the device of E-TFC can further include: second processing module 50.

Second processing module 50, be used for first select available E-TFC that module 20 will select as this carrier wave after the E-TFC that this carrier set is used, if the E-TFC that carrier wave uses in residing each carrier set is identical, with this E-TFC as the final E-TFC that uses.

In Fig. 2 D, if carrier wave k is identical with the E-TFC that uses at the TS2 time slot at the E-TFC that the TS1 time slot uses, then with the E-TFC of this E-TFC as final use.

For the carrier wave that is in a plurality of carrier set together (number of carriers in each carrier set without limits), because it has all respectively selected maximum available E-TFC in different sets, in order further to improve the resource utilization and the efficient of multicarrier, can upgrade first E-TFC that selects module 20 to select.

Enumerate several update modes below respectively.

Mode one, the final E-TFC that uses are the minimum value among the E-TFC that selects in each set, therefore, some set will have certain dump power, have the set power of dump power to upgrade to these: the carrier wave of non-public intersection carrier wave selects bigger E-TFC making full use of dump power in the set, but should satisfy Power Limitation.

Concrete, the embodiment of the invention selects the device of E-TFC can further include: first update module 60, and referring to Figure 1B.

First update module 60, be used for first select available E-TFC that module will select as this carrier wave after the E-TFC that this carrier set is used, if a carrier wave is determined the transmitting power of the E-TFC that this carrier wave uses in each carrier set at least two carrier set;

Do poorly with other transmitting powers the transmitting power of minimum respectively, the difference that obtains is adjusted difference as first of the carrier set of other transmitting power correspondences;

The E-TFC that the E-TFC of the transmitting power correspondence of minimum is used in each carrier set as this carrier wave, and from the E-TFC of other carrier waves of other transmitting power correspondences, reselect and satisfy first E-TFC that imposes a condition, wherein first impose a condition be the transmitting power sum of the E-TFC correspondence reselected in the same carrier set deduct reselect before the difference maximum of transmitting power sum of E-TFC correspondence, and difference is not more than first of this carrier set correspondence and adjusts difference.

Such as: among Fig. 2 D, carrier wave k supposes that the E-TFC that carrier wave k uses is E-TFC in TS1 in second carrier set of first carrier set of authorizing time slot TS1 correspondence and mandate time slot TS2 correspondence _{A, k}The E-TFC that carrier wave k uses in TS2 is E-TFC _{B, k}The E-TFC that carrier wave j uses in TS1 is E-TFC _{A, j}The E-TFC that carrier wave i uses in TS1 is E-TFC _{B, i}E-TFC _{A, k}Corresponding transmitting power is less than E-TFC _{B, k}Corresponding transmitting power.

The transmitting power of determining the E-TFC that carrier wave k uses earlier in each carrier set is E-TFC _{A, k}And E-TFC _{B, k}, and definite E-TFC _{A, k}Corresponding transmitting power is minimum transmitting power.

Use E-TFC _{B, k}Corresponding transmitting power deducts E-TFC _{A, k}Corresponding transmitting power, the difference that obtains is as the first adjustment difference of the carrier set of other transmitting power correspondences.

With E-TFC _{A, k}Gather the E-TFC that uses on the corresponding mandate time slot as carrier wave k at first carrier, with E-TFCA, the E-TFC that k uses on the mandate time slot of the second carrier set correspondence as carrier wave k.

Because with E-TFC _{B, k}Be updated to E-TFC _{A, k}, this is for second carrier set remaining power to be arranged, and promptly first adjusts difference, so need reselect E-TFC to other carrier waves except that carrier wave k in second carrier set (being carrier wave i).

Again to other select the condition of carrier waves be the transmitting power sum of the E-TFC correspondence of other carrier waves after selecting deduct select before the value of transmitting power sum of E-TFC correspondence of other carrier waves be not more than first and adjust difference, and this difference is (E-TFC that can reselect enables to satisfy the transmitting power sum and is not more than first all E-TFC that adjust the condition of difference) of all E-TFC that can select and middle maximum.That is to say, for carrier wave i, for carrier wave j, from the E-TFC of carrier wave j, reselect and satisfy first E-TFC that imposes a condition,, first imposes a condition is exactly that the E-TFC of the carrier wave i that reselects deducts the difference maximum of the E-TFC before reselecting, and can not adjust difference greater than first.

The mode of reselecting E-TFC has a lot, such as adopting similar first to select module 20 to select the mode of E-TFC.

The final E-TFC that uses of carrier wave k can use following formulate:

min{E-TFC _A，k，E-TFC _B，k}＝E-TFC _A，k

Upgrade the E-TFC of carrier wave i in second carrier set,, except the mode of introducing above, also have a lot of execution modes to make full use of dump power:

Such as E-TFCA, k and E-TFCB, the difference of the β value of k correspondence is Δ β _{0, e}, then make that for carrier wave i selects bigger E-TFC the difference of the β value that the β value of new E-TFC correspondence is corresponding with the current E-TFC of carrier wave i is being not more than Δ β _{0, e}Prerequisite under, the maximum that the β value increases.

Mode two, the final E-TFC that uses are the maximum among the E-TFC that selects in each set, therefore, some set will lack certain power, and these set powers that lack power are upgraded: the carrier wave of non-public intersection carrier wave is selected to be slightly smaller than the E-TFC that has selected at present and is satisfied the carrier wave demand fully to vacate power in the set.

Concrete, the embodiment of the invention selects the device of E-TFC can further include: second update module 70, and referring to Fig. 1 C.

With E-TFC _{B, k}Gather the E-TFC that uses on the corresponding mandate time slot as carrier wave k at first carrier, with E-TFC _{B, k}The E-TFC that on the mandate time slot of the second carrier set correspondence, uses as carrier wave k.

Because with E-TFC _{A, k}Be updated to E-TFC _{B, k}, this is that set has the certain power of lacking for first carrier, promptly second adjusts difference, so need reselect E-TFC to other carrier waves (being carrier wave j) except that carrier wave k in the first carrier set.

Again to other select the condition of carrier waves be the transmitting power sum of the E-TFC correspondence of other carrier waves before selecting deduct select after the value of transmitting power sum of E-TFC correspondence of other carrier waves be not less than second and adjust difference, and this difference is minimum among all E-TFC that can select (E-TFC that can select enables to satisfy the transmitting power sum and is not less than second all E-TFC that adjust the condition of difference).That is to say, for carrier wave j, reselect from the E-TFC of carrier wave j and satisfy second E-TFC that imposes a condition, second imposes a condition is exactly that the E-TFC that reselects carrier wave j before deducts the difference minimum of the E-TFC that reselects, and can not adjust difference less than second.

The final E-TFC that uses of carrier wave k can use following formulate:

max{E-TFC _A，k，E-TFC _B，k}＝E-TFC _B，k

Need to prove that the embodiment of the invention is not limited to above-mentioned three kinds of modes, other can be under the situation that the carrier wave that is in a plurality of carrier set is arranged, and the mode that the E-TFC that selects in the step 302 is upgraded all is to use the embodiment of the invention.

As shown in Figure 4, the embodiment of the invention selects the device of E-TFC to comprise for second kind: the second set determination module 400, available E-TFC determination module 410 and second are selected module 420.

The second set determination module 400 is used for will remaining carrier wave and placing second carrier set all not having the carrier wave of identical mandate time slot to place the first carrier set with other any carrier waves.

Wherein, the second set determination module 400 was gone back situation one line and is judged whether the mandate of current TTI has the situation of launching a plurality of carrier waves at same time slot simultaneously before determining carrier set, if having, then determine carrier set; If a plurality of intercarriers of the mandate that distributes for user terminal do not have common time slot fully, then adopt the single carrier rule to do the E-TFC selection for these carrier waves.

In specific implementation process, the second set determination module 400 is the allocation of carriers carrier set of current TTI, will all not have the carrier wave of identical mandate time slot to place the first carrier set with other any carrier waves, will remain carrier wave and place second carrier set.

Division to carrier set is elaborated below.

Shown in Fig. 2 A, because carrier wave j and carrier wave k have a common mandate time slot, carrier wave i and carrier wave k have a common mandate time slot, and all only need to divide a carrier set (i.e. second carrier set), comprise carrier wave i, carrier wave j and carrier wave k in second carrier set.

Shown in Fig. 2 B, because three carrier waves of carrier wave i, carrier wave j and carrier wave k all do not have the mandate time slot identical with other carrier waves, so the same carrier set of division (being the first carrier set) that only needs comprises carrier wave i, carrier wave j and carrier wave k in the first carrier set.

Shown in Fig. 2 C, because carrier wave j and carrier wave k have a common mandate time slot, carrier wave i is the mandate time slot identical with other carrier waves not, so need to divide two carrier set, wherein comprises carrier wave i in the first carrier set; Comprise carrier wave j and carrier wave k in second set.

Shown in Fig. 2 D, because carrier wave j and carrier wave k have a common mandate time slot, carrier wave i and carrier wave k have a common mandate time slot, and carrier wave l does not have the mandate time slot identical with other carrier waves, so need to divide two carrier set, wherein comprise carrier wave 1 in the first carrier set; Comprise carrier wave i, carrier wave j and carrier wave k in second set.

Available E-TFC determination module 410 is used to adopt the mode of single carrier E-TFC, determines an ordering E-TFC of each carrier wave in each carrier set.

Second selects module 420, be used for the transmitted data amount of the ordering E-TFC correspondence of each carrier wave in second carrier set is compared, and determine that according to data quantity transmitted is descending each carrier wave carries out the order that E-TFC selects, according to the order of determining each carrier wave being carried out E-TFC selects, determine the E-TFC that carrier wave uses in second carrier set, the available horsepower of the E-TFC correspondence that each carrier wave of wherein selecting uses be user terminal on this carrier wave, obtain all authorize the minimum value of the residue available horsepower of time slots.

Wherein, because each carrier wave all is to select the E-TFC that sorts according to the mode of single carrier E-TFC, so in order to guarantee the transmitted data amount maximum of second carrier set, need the transmitted data amount of the ordering E-TFC correspondence of each carrier wave in second carrier set be compared, and according to from big to small order, determine the E-TFC of a carrier wave use according to the current residual available horsepower after, the current residual available horsepower is deducted the transmitting power of the E-TFC correspondence of this carrier wave use, the value that obtains is as the current residual available horsepower after upgrading, continue to determine the E-TFC that next carrier wave uses then, up to the current residual available horsepower be 0 or all carrier waves all determined the E-TFC that uses.

That is to say, second selects module 420 according to choosing order then each carrier wave to be carried out E-TFC selects, after determining the E-TFC that a carrier wave uses, the difference of transmitting power that the dump power of current mandate time slot is deducted the E-TFC correspondence that this carrier wave uses is as the dump power of the current mandate time slot after upgrading.

It is a variety of to determine that according to available horsepower the mode of E-TFC has: when selecting E-TFC such as carrier wave, judge each E-TFC, see its corresponding carrier transmit power whether greater than the restriction of the available horsepower of this carrier wave (if this carrier wave has a plurality of mandate time slots, then the maximum available power of this carrier wave is this carrier wave all authorizes the residue available horsepower of the minimum mandate time slot of dump power in time slots), if satisfy restriction then this E-TFC is available E-TFC, maximum E-TFC becomes the E-TFC that this carrier wave uses among the available E-TFC.

In Fig. 2 D, comprise carrier wave i, carrier wave j and carrier wave k in second carrier set, that adopt respectively that the mode of single carrier E-TFC determines carrier wave i ordering is E-TFC _{A, i}, that carrier wave j sorts is E-TFC _{A, j}, what carrier wave k sorted is that E-TFC is E-TFC _{A, k}

Suppose E-TFC _{A, j}Corresponding data volume is greater than E-TFC _{A, k}Corresponding data volume is greater than E-TFC _{A, i}Corresponding data volume (perhaps transmission block size) is then determined the E-TFC that carrier wave j uses earlier, owing to the current residual available horsepower is not distributed, so can be directly with E-TFC _{A, j}E-TFC as carrier wave j uses also can reappear the E-TFC that determines that carrier wave j uses according to the current residual available horsepower;

Then available horsepower is determined that E-TFC deducts the transmitting power of the E-TFC correspondence of carrier wave j use, the value that obtains is as the current residual available horsepower after upgrading;

According to current residual available horsepower (the current residual available horsepower after promptly upgrading), determine the E-TFC that carrier wave k uses;

At last available horsepower is determined that E-TFC deducts the transmitting power of the E-TFC correspondence of carrier wave k use, the value that obtains is as the current residual available horsepower after upgrading;

According to current residual available horsepower (i.e. current residual available horsepower after twice renewal), determine the E-TFC that carrier wave i uses.

Wherein, the embodiment of the invention selects the device of E-TFC can further include for second kind

The 3rd selects module 430, be used for after available E-TFC determination module 410 is determined an ordering E-TFC of each each carrier wave of carrier set, with an E-TFC that ordering E-TFC uses in the first carrier set as this carrier wave of this carrier wave in the first carrier set.

It can be user terminal that the embodiment of the invention is selected the device of E-TFC for second kind, also can be the equipment of network side, can also be a new equipment.

As shown in Figure 5, the embodiment of the invention selects the method for E-TFC to comprise the following steps: for second kind

Step 501, will all not have the carrier wave of identical mandate time slot to place first carrier set, will remain carrier wave and place second carrier set with other any carrier waves.

Step 503, the transmitted data amount of the ordering E-TFC correspondence of each carrier wave in second carrier set is compared, and determine that according to data quantity transmitted is descending each carrier wave carries out the order that E-TFC selects.

Step 504, according to the order of determining each carrier wave is carried out E-TFC and select, determine the E-TFC that carrier wave uses in second carrier set, the available horsepower of the E-TFC correspondence that each carrier wave of wherein selecting uses be user terminal on this carrier wave, obtain all authorize the minimum value of the residue available horsepower of time slots.

Wherein, concrete detailed description of dividing can be referring to the appropriate section of the second set determination module 400 in the device of second kind of selection of embodiment of the invention E-TFC in the step 501.

Because each carrier wave all is to select the E-TFC that sorts according to the mode of single carrier E-TFC in the step 502, so in order to guarantee the transmitted data amount maximum of second carrier set, need in the step 503 transmitted data amount of the ordering E-TFC correspondence of each carrier wave in second carrier set is compared, in the step 504 according to from big to small order, determine the E-TFC of a carrier wave use according to the current residual available horsepower after, the current residual available horsepower is deducted the transmitting power of the E-TFC correspondence of this carrier wave use, the value that obtains is as the current residual available horsepower after upgrading, continue to determine the E-TFC that next carrier wave uses then, up to the current residual available horsepower be 0 or all carrier waves all determined the E-TFC that uses.

That is to say, according to choosing order then each carrier wave being carried out E-TFC in the step 504 selects, after determining the E-TFC that a carrier wave uses, the difference of transmitting power that the dump power of current mandate time slot is deducted the E-TFC correspondence that this carrier wave uses is as the dump power of the current mandate time slot after upgrading.

Wherein, can further include after the step 502

Step a503, with an E-TFC that ordering E-TFC uses in the first carrier set as this carrier wave of this carrier wave in the first carrier set.
