In the LTE of Rel-8 version agreement, uply only can adopt the single-antenna transmission technology at synchronization, so single UE (User Equipment, user terminal) upstream multi-antenna pattern can only be SIMO (Single-Input Multiple-Output, single input exports) or SISO (Single-Input Single-Output, the single output of single input).And in the LTE-A of Rel-10 version agreement, introduced up SU-MIMO (Single users Multiple-Input Multiple-Output, alone family multiple-input and multiple-output) technology for further improving system spectral efficiency.UE uplink antenna amount mostly is 4 most in Rel-10 version LTE agreement, and the streams of code words quantity of transmission is 2 to the maximum.
Dominated formulate in the up PUSCH transmitting power of the LTE of Rel-8 version agreement is:
P PUSCH(i)=min{P MAX,10log 10(M PUSCH(i))+P O_PUSCH(j)+α(j)·PL+Δ TF(i)+f(i)}
In the above-mentioned formula:

P O_PUSCHThe minimum emissive power of UE when satisfying the transmission requirement when (j) path loss impact (supposing that UE is just in base station side) is not considered in expression.
The value of α has that α={ 0,0.4,0.5,0.6,0.7,0.8,0.9,1} is the parameter that the residential quarter of 3 bits is determined, is provided by the upper strata.The complete path loss compensation of α=1 expression, namely each user to arrive the signal to noise ratio of the signal of base station be identical, the transmitting power of Cell Edge User is very high; α=0 expression does not have the path loss compensation, and the base station can be very high to the received power of Cell Center User, and is very low to the received power of Cell Edge User; 0<α<1 expressed portion is divided the path loss compensation, and the loss of Cell Center User path loss compensation is very little, and the loss of Cell Edge User path loss compensation is larger.It is little that this design can guarantee that the Cell Center User throughput descends, simultaneously so that Cell Edge User has reducing to a certain degree to the interference of neighbor cell.

Wherein BPRE is got by the amount of bits of streams of code words carrying and RE number (Resource Element, the Resource Unit) calculating that distributes for this streams of code words, and specific formula for calculation is as follows:
BPRE = Σ r = 0 C - 1 K r / N RE
C is the encoding block quantity of the user data of up PUSCH in the following formula, and wherein the coded block size of r encoding block is K rN REFor system is the RE quantity that PUSCH distributes.
Or work as the ascending control information that only has that transmits in the up streams of code words, then the computing formula of BPRE is:
BPRE=O CQI/N RE
O in the following formula CQIAmount of bits for the upload control data of PUSCH carrying.
Delta TF parameter can make eNB (evolved Node B, evolution Node B) can launch fast MCS (the Modulation and Coding Scheme of streams of code words according to UE, coded modulation scheme) adjusts PUSCH (the Physical Uplink Shared Channel that UE launches, Physical Uplink Shared Channel) PSD (Power Spectral Density, power spectral density).The effect of Delta TF parameter is that PSD and MCS are associated, and helps eNB to reach the purpose of the PSD of rapid adjustment UE emission by the MCS that distributes to UE, reduces and disturbs, and increases throughput of system.
The control procedure formula of the up PUSCH transmitting power of Rel-10 version LTE agreement is:
P PUSCH , c ( i ) = min P CMAX , c ( i ) , 10 log 10 ( M PUSCH , c ( i ) ) + P O _ PUSCH , c ( j ) + α c ( j ) · PL c + Δ TF , c ( i ) + f c ( i )
In the above-mentioned formula:
P CMAX, c(i) be the maximum transmitting power that allows of PUSCH on this carrier wave, depend on the power class with UE, determined the maximum capacity of UE transmitting power.
M PUSCH, c(i) be the PUSCH resource size that the subframe i on this carrier wave upward distributes, represent with RB, the number of the RB that namely distributes, the PSD on each RB that UE distributes equates, and transmitting power is directly proportional with the RB number that distributes.
P O_PUSCH, c(j) represent on this carrier wave do not consider path loss impact (supposing that UE is just in base station side) time minimum emissive power of UE when satisfying the transmission requirement.
α c(j) expression is part path loss penalty coefficient on this carrier wave, α c(j) value has α c{ 0,0.4,0.5,0.6,0.7,0.8,0.9,1} is the definite parameter in residential quarter of 3 bit to ∈, is provided by the upper strata.α c(j)=1. the complete path loss of expression compensation, namely each user to arrive the signal to noise ratio of the signal of base station be identical, the transmitting power of Cell Edge User is very high; α c(j)=0. expression does not have the path loss compensation, and the base station can be very high to the received power of Cell Center User, and is very low to the received power of Cell Edge User; 0<α c(j)<1 expressed portion is divided the path loss compensation, and the loss of Cell Center User path loss compensation is very little, and the loss of Cell Edge User path loss compensation is larger.It is little that this design can guarantee that the Cell Center User throughput descends, simultaneously so that Cell Edge User has reducing to a certain degree to the interference of neighbor cell.

When uplink is the single codeword flow transmission, Δ TF, c(i) be 2 BPRE and K SThe power of product subtract again after 1 and the user data on the PUSCH and the side-play amount of control information Product get.
The specific formula for calculation of Delta TF is as follows:
Δ TF , c ( i ) = 10 log 10 ( ( 2 BPRE · K s - 1 ) · β offset PUSCH )
Wherein the value 1.25 or 0 of Ks when the Ks value is 1.25, does not have user data in the up PUSCH transmission, and when only having the control signal data, the account form of BPRE is as follows:
BPRE=O CQI/N RE
The account form of BPRE is as follows in all the other situations:
BPRE = Σ r = 0 C - 1 K r / N RE
C is the encoding block quantity of the user data of the up PUSCH on this carrier wave in the following formula, and wherein the coded block size of r encoding block is K rN REFor system is the RE quantity that the PUSCH on this carrier wave distributes.
Work as K SValue is 0 o'clock, Δ TF, c(i) be 0.

Because above-mentioned, when UE collocating uplink dicode word flow transmission, Ks fixedly value is 0 in the LTE system of Rel-10 version, and eNB can not launch the PSD of PUSCH with UE and the MCS of the up streams of code words of UE associates by Delta TF parameter at this moment.Therefore eNB can't reach the purpose by the MCS rapid adjustment UE emission PSD that distributes to UE.
And change more violent when wireless channel environment, the MCS grade of one of up pair of streams of code words or up pair of streams of code words changes larger within the time interval of a sub-frame duration length, then this moment, UE can't mate the emission PSD of UE and the MCS grade of up pair of streams of code words of UE fast by Delta TF parameter, also can't in time pass through closed loop TPC (Transmitter Power Control, transmitter power control) order UE adjusts its emission PSD, will cause the hydraulic performance decline of system.
