Specific implementation mode

In order to make the purpose, technological means and advantage of the application be more clearly understood, the application is done below in conjunction with attached drawing It is further described.

Present invention assumes that at least there are two types of different upper of business importance in one or more serving cells that UE is configured Row data transmission.

The application provides a kind of Poewr control method configured with different importance business, and Fig. 2 is the basic flow of this method Journey schematic diagram.As shown in Fig. 2, this method includes：

Step 201：For each service signal being allocated on the physical channel of UE transmitted in synchronization, according to each The importance of a business determines its corresponding power distribution priority；

In the prior art, for the signal of different time-gap initial position, the preceding signal A in initial position is according to current Situation carries out power control, even if subsequently having the higher signal B of priority and A simultaneous transmissions, signal A is still with original power Control result carries out data transmission, be not compromised by own priority it is low and reduce power give signal B use.

And in this application, as long as synchronization transmission each signals of UE, all based on power distribution priority into Row power distribution.Specifically, when the time slot initial position difference of unlike signal, although the preceding signal A in time slot initial position It had determined the transmission power of current time slots, but hair is determined in the higher signal B of rear but priority in time slot initial position When penetrating power, it is still desirable to redefine the transmission power of signal A according to current priority.That is, no matter time slot rises Beginning position it is front and back, as long as synchronization transmission each signals of UE, according to power distribution priority carry out power distribution.

Step 202：According to the power distribution priority determined, transmission power is distributed for corresponding signal.

In the signal of the business to different importance, when distributing transmission power according to power distribution priority, it is preferable that UE It is required that different importance business data transmissions in each serving cell or same serving cell of configuration can be calculated separately Transmission power, further according to the sum of all serving cells or the required transmission power of all signal datas of same serving cell and UE Maximum transmission power magnitude relationship, and configured serving cell the case where, determine each serving cell or same clothes The corresponding transmission power of unlike signal data in cell of being engaged in；UE emits corresponding signal according to the transmission power distributed.

The sum of the required transmission power of each signal of UE configurations described below refers to overlapping each other in synchronization The sum of the required transmission power of each signal.For example, as shown in figure 3, physically row shares channel (PUSCH, Physical Uplink Shared Channel) in transmission time, the PUSCH of the PUSCH and serving cell 2 of serving cell 1 partly overlap, Then the sum of power is the sum of the PUSCH of serving cell 1 and the power of both PUSCH of serving cell 2 in the transmission time.

UE is configured with the different business transmission of two or more importance, configures two kinds of importance differences here with UE Business transmission for illustrate, similar method processing may be used more than the case where two kinds of importance different business.Two The different business of kind importance is referred to as the first business and second of business, for example, the first business can be URLLC industry Business, second of business can be eMBB business, and the importance of the first business is higher than second of business, the transmission of the first business Priority is higher than second of business, that is, the power distribution priority of the first business is higher than second of business.Both industry Business may be transmitted in a serving cell different frequency range, both business may also be transmitted in different service cells. Either UE needs to transmit the different channel signal of importance, for example, the Physical Uplink Control Channel of transmitting uplink control information The priority of (PUCCH, Physical Uplink Control Channel) is higher than the PUSCH of transmission data, and includes uplink The priority for controlling the PUSCH transmission of information is higher than the PUSCH transmission for not including ascending control information.

Embodiment one：

Divide several situations that the determination method of signal transmission power in above-mentioned steps 202 is specifically described below.

Situation one：

UE can calculate the power of signal on all serving cell different channels in time, that is to say, that UE knows carry out work( All parameters that rate control calculates (for example, for close-loop power control, have received transimission power order (TPC) and uplink Resource allocation) time interval for transmitting upstream data is arrived more than or equal to a thresholding, then used according to the case where power calculation Following method carries out power control.

When the sum of the required transmission power of different business signal of UE configurations is less than or equal to the emission maximum of UE configurations When power P cmax, each signal emits respectively according to the transmission power of calculating.In this way, the transmission power in UE is configured less than UE Maximum transmission power under conditions of, fully meet the power demand of each signal.

When the sum of the required transmission power of different business signal of UE configurations is more than the maximum transmission power of UE configurations When Pcmax, power is sequentially allocated from high to low according to the power distribution priority of different business signal, then each signal according to The transmission power of distribution emits respectively.In this way, under conditions of the transmission power of UE is more than the maximum transmission power of UE configurations, it is excellent First meet the power demand of the high service signal of priority, detailed process is as described in Figure 4.

Situation two：

UE configures the different business transmission of two kinds of importance, and the resource of the first business is to be pre-configured, and is not that dynamic is adjusted Degree, for example, the resource configured by high-level signaling, or pass through semi-continuous scheduling (SPS, Semi-persistent Scheduling the resource of resource), second of business is dynamic dispatching；Then, UE transmission services data as needed Situation decides whether to transmit the first business.In this situation, decide whether the time for transmitting the first business in second of business Transmission is small with second of business transmission intercal more than or equal to t1 (t1 is more than or equal to 0) with second of business transmission intercal before starting In t2 (t2 is more than t1), as shown in figure 5, within t1 interval times, UE can be emitted according to the transmission power calculated, In interval time less than t2, UE can not re-start power control calculating.For such case, there are following several processing sides Method.

Method one：

The first business datum and the required transimission power of second of business datum are calculated separately, when the first business number When according to the maximum transmission power Pcmax for being less than or equal to UE configurations with the sum of the required transimission power of second of business datum, Power distribution is carried out according to the first business datum and the required transimission power of second of business datum；When the first business number When according to the maximum transmission power Pcmax for being more than UE configurations with the sum of the required transimission power of second of business datum, according to the A kind of sequence of the power distribution priority of business and second of business from high to low, is sequentially allocated transmission power.For example, when the When a kind of power distribution priority of business is higher than second of business, power is preferentially distributed to the transmission of the first business datum Channel, remaining power distribution give the transmission channel of second of business datum, even if the first business is not transmitted, second of industry The transimission power of business data is still remaining power after the transmission channel power distribution of the first business datum is over, because of UE Whether the sufficient time does not transmit the power for recalculating second of business according to the first business.In entire slot transmission mistake The transimission power of Cheng Zhong, the first business datum and second of business datum is constant.

In following method, all assume that the power distribution priority of the first business is higher than second of business, Ke Yigen According to whether the first business datum is sent, the transimission power of second of business datum is determined.Specifically,

Method two：

A part of Pr (i) of the maximum transmission power of M UE is reserved to the first business data transmission, UE is by remaining work( Rate Pcmax-Pr (i) calculates transimission power P (i) _ 2 of second of business datum, wherein i, j=as the maximum transmission power of UE 1,2 ..., M, and work as i>When j, Pr (i)>Pr (j), M are greater than 1 positive integer, are configured by high-level signaling or are preset by agreement. That is it is respectively (1) Pr to keep for the power of the first business data transmission, Pr (2) ..., Pr (M) are accordingly calculated The transimission power of second of business datum be respectively P (1) _ 2, P (2) _ 2 ..., P (M) _ 2.If according to the first business The transimission power P1 that power control calculates the first business datum is less than or equal to Pr (1), the first business datum uses work( Rate P1 is transmitted, and second of business datum is transmitted using power P (1) _ 2.If according to the power control of the first business The transimission power P1 that system calculates the first business datum is less than or equal to Pr (i) more than Pr (i-1), the first business datum makes It is transmitted with power P1, second of business datum is transmitted using power P (i) _ 2.If according to the work(of the first business Rate control calculate the first business datum transimission power P1 be more than Pr (M), the first business datum using power P 1 into Row transmission, second of business datum is without transmission.During entire slot transmission, the first business datum and second of industry The transimission power for data of being engaged in is constant.

Method three：

First step calculates separately the transmission work(of the first business datum and second of business datum in two ways Rate, wherein first way are that a part for the maximum transmission power for reserving M UE (is respectively { Pr (1), Pr (2) ..., Pr (M) }, and work as i>When j, Pr (i)>Pr (j)) give the first business data transmission, UE to be sent out remaining power as the maximum of UE Penetrate the transimission power of second of business datum of power calculation, respectively P (1) _ 2, P (2) _ 2 ..., P (M) _ 2, wherein M is greater than Positive integer equal to 1 is configured by high-level signaling or is preset by agreement.The second way assumes that the first business datum need not be sent out It send, power P 2 is distributed to the transmission channel of second of business datum.Second step, if the first business datum is passed It is defeated, in the part that the first business and second of business are overlapped, if calculating the according to the power control of the first business A kind of transimission power P1 of business datum is less than or equal to Pr (1), the first business datum is transmitted using power P 1, second Business datum is transmitted using power P (1) _ 2.If calculating the first business according to the power control of the first business The transimission power P1 of data is less than or equal to Pr (i) and is more than Pr (i-1), the first business datum is transmitted using power P 1, the Two kinds of business datums are transmitted using power P (i) _ 2.If the power control according to the first business calculates the first The transimission power P1 of business datum is more than Pr (M), the first business datum is transmitted using power P 1, second of business datum Without transmission；Second is used in the transmission of the first business and the nonoverlapping part of second of business, second of business datum The power P 2 that kind mode calculates is sent.During entire slot transmission, the transimission power of the first business datum is constant, and second What the transimission power of kind business datum may change.

Situation five：

UE configures the different business transmission of two kinds of importance, and two kinds of business are all dynamic dispatchings.Dispatch the first business The DCI of data transmission be less than with second of business transmission intercal before second business is transmitted t1 (t1 is more than or equal to 0) or Decide whether the time for transmitting the first business after second of business is transmitted, as shown in figure 12.For such case, have with Under several processing methods.It is assumed that the power distribution priority of the first business is higher than second of business.

Method one：

A part of Pr of the maximum transmission power of reserved UE gives the first business data transmission, UE using remaining power as The maximum transmission power of UE calculates the transimission power P2 of second of business datum.If according to the power control meter of the first business The transimission power P1 for calculating the first business datum is less than or equal to Pr, the first business datum is transmitted using power P 1, Second of business datum is transmitted using power P 2.If calculating the first industry according to the power control of the first business The transimission power P1 for data of being engaged in is more than Pr, the first business datum is transmitted using power P r, and second of business datum uses Power P 2 is transmitted.During entire slot transmission, the transimission power of the first business datum and second of business datum It is constant.

Method two：

A part of Pr of the maximum transmission power of reserved UE gives the first business data transmission, UE using remaining power as The maximum transmission power of UE calculates the transimission power P2 of second of business datum.If according to the power control meter of the first business The transimission power P1 for calculating the first business datum is less than or equal to Pr, the first business datum is transmitted using power P 1, Second of business datum is transmitted using power P 2.If calculating the first industry according to the power control of the first business The transimission power P1 for data of being engaged in is more than Pr, the first business datum is transmitted using power P 1, in the first business and second At kind business nonoverlapping moment, second of business datum is transmitted using power P 2, in the first business and second of business At the time of overlapping, second of business datum is without transmission.During entire slot transmission, the first business datum and second The transimission power of kind business datum may change.

Method three：

First step calculates separately the transmission work(of the first business datum and second of business datum in two ways Rate, wherein first way are that a part for the maximum transmission power for reserving M UE (is respectively { Pr (1), Pr (2) ..., Pr (M) }, and work as i>When j, Pr (i)>Pr (j)) give the first business data transmission, UE to be sent out remaining power as the maximum of UE Penetrate the transimission power of second of business datum of power calculation, respectively P (1) _ 2, P (2) _ 2 ..., P (M) _ 2, wherein M is greater than Positive integer equal to 1 is configured by high-level signaling or is preset by agreement.The second way assumes that the first business datum need not be sent out It send, power P 2 is distributed to the transmission channel of second of business datum.Second step, the first business and second of business not The transmission of the part of overlapping, second of business datum is sent using the power P 2 that the second way calculates.If the first business Data are transmitted, in the part that the first business and second of business are overlapped, if according to the power control of the first business The transimission power P1 for calculating the first business datum is less than or equal to Pr (1), the first business datum is carried out using power P 1 Transmission, second of business datum are transmitted using power P 1_2.If the power control according to the first business is calculated The transimission power P1 of the first business datum be less than or equal to Pr (i) be more than Pr (i-1), the first business datum using power P 1 into Row transmission, second of business datum are transmitted using power P (i) _ 2.If calculated according to the power control of the first business Out the transimission power P1 of the first business datum is more than Pr (M), the first business datum is transmitted using power P 1, and second Kind business datum is without transmission；During entire slot transmission, the transimission power of the first business datum is constant, second What the transimission power of business datum may change.

Embodiment two：

For after in embodiment one being second traffic assignments transmission power, for the first business and second business The transmission power at overlapping transmission moment, second of business is likely lower than transmission power before this, may be used the present embodiment provides Several ways reduce overlapping time section in second of business transmission power so that the transmission power of its transmission power and distribution It is identical.

First, it is assumed that second of business is to use orthogonal frequency division multiplexing (OFDM, Orthogonal Frequency Division Multiplexing) pass through Physical Uplink Shared Channel (PUSCH, Physical Uplink Shared Channel it) transmits, following seven kinds of methods, which may be used, reduces transmission power.In which it is assumed that the overlapping transmission moment determined The transmission power of second of business is A, and the transmission power for second of the business determined before this is B.

Method one：

On the basis of transmission power B, according to the difference of A and B, reduces in the overlapping transmission moment and transmit according to same ratio Data and ascending control information (UCI, Uplink Control Information) all resource element (RE, Resource Element power), until PUSCH in the overlapping transmission moment transmission power be A, to ensure the overlapping transmission moment section in General power be less than or equal to UE maximum transmission power.

Method two：

On the basis of transmission power B, the number of transmission data and ascending control information RE in the overlapping transmission moment is reduced, And the transimission power for each retaining RE is constant, to reduce the power of entire OFDM symbol, until PUSCH in the overlapping transmission moment Transmission power be A, to ensure the general power in the overlapping transmission moment be less than or equal to UE maximum transmission power.

Method three：

The method for reducing power in the overlapping transmission moment is determined according to data and the modulation system of ascending control information, if Data and ascending control information are first kind modulation systems (for example, data are quadrature phase shift keying (QPSK, Quadrature Phase Shift) modulation system), power in overlapping time section is reduced using the method for the above method one；If data and uplink Control information is the second class modulation system (for example, data are quadrature amplitude modulation (QAM, Quadrature Amplitude Modulation, such as 16QAM) etc. modulation systems), using the above method two method reduce overlapping time section in power.

Method four：

Still include that UCI modulation symbols determine to reduce overlapping time in overlapping time section according to the entirely data for including The method of power in section reduces overlapping time if include in overlapping time section is entirely data using the method for method one Power in section；If including UCI modulation symbols in overlapping time section, overlapping time section internal strength is reduced using the method for method two Rate, at this point, the number of transmission data RE in overlapping time section is first reduced, until the transmission power of PUSCH in overlapping time section For A, to ensure that the general power in overlapping time section is less than or equal to the maximum transmission power of UE.If transmission in overlapping time section The number of data RE does not all have, and the general power in overlapping time section transmission time is still more than the maximum transmission power of UE, at this point, A kind of method is to continue with the number of the power for reducing the RE for transmitting UCI modulation symbols or reduction transmission data UCI modulation symbols RE Mesh, the power that another method is to maintain the RE of transmission UCI modulation symbols is constant, reduces the power of the first business, so that the A kind of general power of business and second of business in overlapping time section is less than the maximum transmission power of UE, in this case The transmission power of PUSCH is no longer A.Wherein, overlapping time section i.e. continuous all overlapping transmission moment.

Method five：

Still include that UCI symbols determine to reduce overlapping time section in the overlapping transmission moment according to the entirely data for including The unit of the method for interior power, decision is OFDM symbol.Specifically, if an OFDM symbol in the overlapping transmission moment includes Be entirely data, using method one method reduce the overlapping transmission moment in the OFDM symbol power so that the hair of PUSCH It is A to penetrate power；If an OFDM symbol in the overlapping transmission moment includes UCI modulation symbols, dropped using the method for method two The power of the OFDM symbol in the low overlapping transmission moment, at this point, first to reduce the transmission of the OFDM symbol overlapping transmission moment Nei The transmission of the number of data RE, until PUSCH in the overlapping transmission moment transmission power be A, to ensure the OFDM symbol General power is less than or equal to the maximum transmission power of UE.If the number of OFDM symbol transmission data RE is all in the overlapping transmission moment Not, in the overlapping transmission moment transmission power of PUSCH still above A, that is to say, that the general power of the OFDM symbol is still big In the maximum transmission power of UE, at this point, a kind of method is to continue with the work(of the RE for the transmission UCI modulation symbols for reducing the OFDM symbol Rate or the number for reducing transmission data UCI modulation symbols RE, another method are to maintain the transmission UCI modulation of the OFDM symbol The power of the RE of symbol is constant, reduces the power of the first business in the OFDM symbol.

Method six：

Still include that UCI modulation symbols determine to reduce overlapping time in overlapping time section according to the entirely data for including The method of power in section.Specifically, if include in overlapping time section is entirely data, weight is reduced using the method for method one Power in the folded period；If including UCI modulation symbols in overlapping time section, first to reduce and transmit number in overlapping time section According to the power of RE, until the transmission power of PUSCH in overlapping time section is A, to ensure the first business in overlapping time section It is less than or equal to the maximum transmission power of UE with the general power of second of business.If the work(of transmission data RE in overlapping time section After rate is 0, the transmission power of PUSCH is still above A, that is to say, that overlapping time section carves the first interior business and second of business General power be still more than the maximum transmission power of UE, at this point, a kind of method is to continue with the RE for reducing transmission UCI modulation symbols Power or the number for reducing transmission data UCI modulation symbols RE, another method are to maintain the RE's of transmission UCI modulation symbols Power is constant, reduces the power of the first business.

Method seven：

Still include that UCI symbols determine to reduce overlapping time section in the overlapping transmission moment according to the entirely data for including The unit of the method for interior power, decision is OFDM symbol.Specifically, if some OFDM symbol packet in the overlapping transmission moment What is contained is entirely data, and the power of the OFDM symbol in the overlapping transmission moment is reduced using the method for method one；If overlapping passes Some OFDM symbol in the defeated moment includes UCI modulation symbols, first to reduce the biography of the OFDM symbol overlapping transmission moment Nei The power of transmission of data RE, until PUSCH in the overlapping transmission moment transmission power be A, to ensure the total work of the OFDM symbol Rate is less than or equal to the maximum transmission power of UE.If the power of OFDM symbol transmission data RE is 0 in the overlapping transmission moment, weight The transmission power of PUSCH is still above A in folded transmission time, that is to say, that the general power of the OFDM symbol is still more than UE most Big transmission power, at this point, a kind of method is to continue with the power of the RE for the transmission UCI modulation symbols for reducing the OFDM symbol or subtracts The number of few transmission data UCI modulation symbols RE, another method are to maintain the RE of the transmission UCI modulation symbols of the OFDM symbol Power it is constant, reduce the power of the first business of the OFDM symbol.

Here illustratively, may include multiple OFDM symbols in overlapping time section, in four~method of the above method seven, Judge whether there are two types of the decision units comprising UCI symbols：One is make all OFDM symbols in section of entire overlapping time To be whole to determine whether comprising UCI symbols, i.e. method four and method six；Another kind is by each OFDM in overlapping time section Whether symbol judges in single OFDM symbol to include UCI symbols, i.e. method five and method seven as individual.

If assuming, second of business carries out PUSCH transmission using SC-FDM, and following five kinds of methods, which may be used, reduces transmitting Power.

Method one '：

On the basis of transmission power B, according to the difference of A and B, is reduced according to same ratio and transmit number in overlapping time section According to ascending control information (UCI, Uplink Control Information) all resource element (RE, Resource Element power), until PUSCH in the overlapping transmission moment transmission power be A, to ensure in the overlapping transmission moment General power is less than or equal to the maximum transmission power of UE.

Method two '：

On the basis of transmission power B, transmission data and ascending control information modulation symbol number in overlapping time section are reduced, The modulation symbol of partial data and ascending control information is namely set to 0, then carries out transformation precoding (Transform Precoding) namely discrete Fourier variation (DFT) processing, to reduce the power of entire OFDM symbol, until overlapping transmission The transmission power of moment PUSCH is A, to ensure that the general power in overlapping time section is less than or equal to the maximum transmission power of UE. Specifically operating procedure is：Assuming that the data transmitted and ascending control information modulation symbol collection is needed to be combined into { s₀,s₁,…,s_N-1, A portion data and ascending control information modulation symbol are set to 0, for example, { s₀,s₁,…s_M, 0 ..., 0 }, i.e., from s_M+1Extremely s_N-1It is all set to 0, other modulation symbols are constant, can reduce the power of total SC-FDM symbols in this way, reduce the value of M, have More modulation symbols are set to 0, then the power of SC-FDM symbols is smaller, therefore, reduce the value of M until in overlapping time section General power is less than or equal to the maximum transmission power of UE.

Method three '：

The method for reducing power in overlapping time section is determined according to data and the modulation system of ascending control information, if number It is first kind modulation system (for example, data are quadrature phase shift keying (QPSK, Quadrature according to ascending control information Phase Shift) modulation system), power in overlapping time section is reduced using the method for the above method one '；If data and upper Row control information is the second class modulation system (for example, data are quadrature amplitude modulation (QAM, Quadrature Amplitude Modulation, such as 16QAM) etc. modulation systems), using the above method two ' method reduce overlapping time section in power.

Method four '：

Still include that UCI modulation symbols determine to reduce overlapping time in overlapping time section according to the entirely data for including The method of power in section reduces overlapping time if include in overlapping time section is entirely data using the method for method one ' Power in section；If including UCI modulation symbols in overlapping time section, reduced in overlapping time section using the method for method two ' Power, at this point, overlapping time intersegmental part point or total data modulation symbol are first set to 0, until in overlapping time section PUSCH transmission powers are A, to ensure that the general power in overlapping time section is less than or equal to the maximum transmission power of UE.If weight After all data modulation symbols are set to 0 in the folded period, the power of overlapping time section is still above A, that is to say, that when overlapping Between general power in section be still more than the maximum transmission power of UE, at this point, a kind of method is to continue with reduction transmission UCI modulation symbols RE power, alternatively, part UCI modulation symbols are set to 0, another method is to maintain the RE's of transmission UCI modulation symbols Power is constant, reduces the power of the first business.

Method five '：

Still include that UCI symbols determine to reduce in overlapping time section in overlapping time section according to the entirely data for including The unit of the method for power, decision is SC-FDM symbols.Specifically, if some SC-FDM symbol in the overlapping transmission moment Including be entirely data, using method one ' method reduce the overlapping transmission moment in the SC-FDM symbols power；If weight Some SC-FDM symbol in folded transmission time includes UCI modulation symbols, when reducing overlapping transmission using the method for method two ' The power of the SC-FDM symbols in carving, at this point, first to set the data modulation symbol of the SC-FDM symbols in the overlapping transmission moment Be 0, until PUSCH in the overlapping transmission moment transmission power be A, to ensure that the general power of the SC-FDM symbols is less than or equal to The maximum transmission power of UE.If all data modulation symbols of the SC-FDM symbols are set to 0 in overlapping transmission time section Afterwards, overlapping time section transmission time in PUSCH transmission power still above A, that is to say, that the total work of the SC-FDM symbols Rate is still more than the maximum transmission power of UE, at this point, a kind of method is to continue with the transmission UCI modulation symbols for reducing the SC-FDM symbols Number RE power, alternatively, part UCI modulation symbols are set to 0, another method is to maintain the transmission of the SC-FDM symbols The power of the RE of UCI modulation symbols is constant, reduces the power of the first business of the SC-FDM symbols.

Here illustratively, may include multiple SC-FDM symbols in overlapping time section, in the above method four ' and method In five ', judge whether there are two types of the decision units comprising UCI symbols：One is by entire overlapping time section in all SC- FDM symbols are as a whole to determine whether comprising UCI symbols, i.e. method four '；Another kind is will be each in overlapping time section Whether SC-FDM symbols judge in single SC-FDM symbols to include UCI symbols, i.e. method five ' as individual.
