The preferred embodiment of the present invention is described in detail with reference to the accompanying drawing.
Embodiment one
The embodiment of the present invention provides a kind of ascending power control method, and this method can be applied to network rack shown in FIG. 1 In structure.As shown in Fig. 2, this method may comprise steps of:
S11: base station to terminal send power configuration information, power configuration information for configurating terminal in NR system and Uplink maximum transmission power in LTE system.
In the embodiment of the present invention, base station can be the master base station in two base stations for carrying out dual link with terminal.It base station can Power configuration information is sent to terminal in a manner of by being semi-statically configured, to notify terminal in NR system and in LTE system In uplink maximum transmission power.
In practical applications, the power configuration information that base station is sent can use but be not limited only to following manner:
Mode one: base station is semi-statically configured uplink maximum transmission power of the terminal in NR system and LTE system, i.e., directly Uplink maximum transmission power of the configurating terminal in NR system, such as PCmax, NRAnd uplink of the configurating terminal in LTE system is most Big transmission power, such as PCmax, LTE。
Mode two: base station is semi-statically configured the ratio system of terminal uplink maximum transmission power in NR system and LTE system The total uplink emission maximum function of the uplink maximum transmission power difference occupied terminal of number, i.e. instruction in NR system and LTE system The ratio of rate.
Then terminal can determine respectively after receiving power configuration information according to the proportionality coefficient of uplink maximum transmission power Uplink maximum transmission power in NR system and LTE system.
For example, if the proportionality coefficient of the uplink maximum transmission power configured in power configuration information is LNR: LLTE=2:3, such as The total uplink maximum transmission power of fruit terminal is 200mW, then can determine uplink maximum transmission power of the terminal in NR system, Such as it can indicate are as follows: PCmax, NR=80mW, and determine uplink maximum transmission power of the terminal in LTE system, such as can To indicate are as follows: PCmax, NR=120mW.
S12: what base station reception terminal was sent reports information, reports information for characterizing terminal in NR system and LTE system In uplink transmission power use state.
In the embodiment of the present invention, reporting information may include the terminal currently corresponding function in NR system and LTE system The state parameter of upstream data to be transmitted in rate surplus and/or terminal, the state parameter can be used for characterizing terminal transmission to To the desirability of uplink transmission power when the upstream data of transmission.
Wherein, corresponding power headroom can refer to that terminal allows in each system in NR system and LTE system Maximum transmission power (the uplink maximum transmission power configured) and the currently practical uplink power used between difference Value.
For example, power headroom of the terminal in NR system can indicate are as follows: PHNR=PCmax, NR- P1, wherein P1 is terminal The currently actual uplink transmission power in NR system.Power headroom of the terminal in LTE system can indicate are as follows: PHLTE= PCmax, LTE- P2, wherein P2 is the terminal currently actual uplink transmission power in LTE system.
State parameter may include cache size and/or service quality scale value (QoS Class Identifier, QCI), Cache size can be used for characterizing the buffer memory of upstream data to be transmitted, and QCI can be used for characterizing the important of upstream data to be transmitted Property.
In practical applications, the upstream data of different service types can have different weight coefficients.For example, to higher Biggish weight coefficient value is arranged in the upstream data of the type of service of QCI demand.And cache size can be according to weight coefficient Value (such as x) and the buffer memory of the upstream data of each type of service (as b) determine report state parameter.
For example, if upstream data corresponds to k kind type of service, and the upper line number of each type of service in upstream data According to weight coefficient and buffer memory is corresponding with, then the cache size in state parameter can be x1*b1+x2*b2+ ... xk*bk.Its In, when x*b represents the upstream data for transmitting a kind of type of service, desirability of the terminal to uplink transmission power.Usually, The uplink transmission power that the more big then GC group connector of cache size needs is bigger.
S13: base station is according to reporting uplink maximum transmission power of the information adjustment terminal in NR system
In the embodiment of the present invention, base station can according to report information determine for adjusting uplink of the terminal in NR system most The power adjustment parameters of big transmission power, the power adjustment parameters can according to reporting, information is determining to be needed to adjust terminal in base station Identified parameter when uplink maximum transmission power in NR system, so that terminal increases or subtracts according to the power adjustment parameters Uplink maximum transmission power in small NR system is adjusted.
In the embodiment of the present invention, mainly said for the uplink maximum transmission power in NR system by increasing terminal It is bright.So, when determining power adjustment parameters in S13, base station can be according to reporting information to determine the of terminal in NR system The second power headroom of one power headroom and terminal in LTE system, and then judge the first power headroom and the second power headroom Whether the state parameter for whether meeting the first preset condition and upstream data to be transmitted meets the second preset condition；Wherein, first Preset condition is that the first power headroom is less than or equal to the first power headroom threshold value, and the second power headroom is more than or equal to the second power Margin threshold；Second preset condition is the cache size in the first state parameter of upstream data to be transmitted of the terminal in NR system More than or equal to the first preset cache threshold value, and/or, the second state parameter of to be transmitted upstream data of the terminal in LTE system In cache size be less than or equal to the second preset cache threshold value.
If base station determines the first power headroom and the second power headroom meets the first preset condition, and upstream data to be transmitted State parameter meet the second preset condition, then base station determination can increase uplink emission maximum function of the terminal in NR system Rate.
Therefore, it can be used alone the state ginseng of the upstream data to be transmitted of power headroom or terminal in the judgment process Number, or the uplink maximum transmission power that can also be determined the need in conjunction with the two to terminal in NR system are adjusted It is whole.
Therefore, the deterministic process carried out in S13 includes but are not limited to following situations:
Situation 1: base station determines that the power headroom in NR system is larger, or determines that the power headroom in LTE system is smaller Or be 0, then do not increase the uplink maximum transmission power in NR system.
Situation 2: base station determines that the power headroom in NR system is smaller, and determines that the power headroom in LTE system is larger, then The uplink maximum transmission power in NR system can be increased.
Situation 3: base station determines that the power headroom in NR system is smaller and power headroom in LTE system is larger, while base The state parameter stood in conjunction with the upstream data to be transmitted of terminal is maximum to determine the need for uplink to terminal in NR system Transmission power is adjusted.At this time may include the following contents:
1) if the larger and/or QCI of upstream data caching is more demanding in LTE system, illustrate that base station is needed in LTE system In distribute more resource as far as possible for terminal, bigger transmission power is needed, even if more than the power in the LTE system that terminal reports Measure it is larger, at this point, not increasing the uplink maximum transmission power in NR system.
2) if upstream data caching is less in LTE or QCI requirement is lower, and the cache size of the upstream data in NR system Larger or QCI is more demanding, at this point, base station can determine the uplink maximum transmission power increased in NR system.
Situation 4: base station determines that the power headroom in NR system is larger, and determine LTE system in power headroom it is smaller or Person is 0, and base station determines that upstream data caching is larger in NR system and/or QCI requirement is lower, alternatively, upper line number in LTE system According to caching, larger and/or QCI is more demanding.At this point, base station can determine the uplink emission maximum for reducing terminal in NR system Power.
It should be noted that after the adjustment, the uplink maximum transmission power that terminal configures in NR system and LTE system The sum of may be more than the maximum transmission power that can support of terminal, but during actual transmissions, the actual uplink of terminal is sent out Penetrating power can't be more than the maximum transmission power that terminal can be supported.Alternatively, adjusting uplink of the terminal in NR system most While big transmission power, the uplink maximum transmission power in LTE system can also be adjusted.
In the embodiment of the present invention, the uplink maximum transmission power to terminal in NR system is needed to be adjusted in determination When, it can determine the power adjustment parameters for terminal.The power adjustment parameters can be the uplink adjusted in NR system Maximum transmission power, alternatively, can be uplink emission maximum current in uplink maximum transmission power adjusted and NR system Power difference between power.For example, it is desired to which then the difference can when increasing uplink maximum transmission power of the terminal in NR system Think positive number.
Base station can pass through Downlink Control Information (Downlink Control after determining power adjustment parameters Infornation, DCI) or high-level signaling (such as MAC CE) dynamically indicated that the DCI can be scheduling physical uplink Shared channel (Physical Uplink Shared Channel, PUSCH) transmission and/or scheduling Physical Downlink Shared Channel (Physical Downlink Shared Channel, PDSCH) transmission DCI, alternatively, the DCI be also possible to dedicated for The DCI of power adjustment.
In the embodiment of the present invention, base station can indicate uplink maximum transmission power adjusted by the following two kinds mode.
Mode one: between the uplink maximum transmission power and current uplink maximum transmission power after the instruction adjustment of base station Difference.
At this point, the difference that 2 bit informations are used to indicate uplink maximum transmission power before and after adjustment can be increased in DCI.Example Such as, 00 instruction -1dB of bit, bit 01 indicate that 0dB, bit 10 indicate that 1dB, bit 11 indicate 2dB.
Then after sending DCI in this mode to terminal, terminal can be according to current uplink maximum transmission power for base station With DCI carry difference newest maximum transmission power is calculated, thus to the uplink maximum transmission power in NR system into Row adjustment.
For example, base station determines terminal in NR system, dispatches in the DCI of PUSCH transmission and indicated by bit information " 10 " Dynamic power adjustment, terminal can determine power adjustment parameters according to the bit information " 10 " in the DCI of scheduling PUSCH transmission For 1dB, then terminal uplink maximum transmission power adjusted in NR system is PCmax, NR+1dB。
Mode two: base station directly indicates uplink maximum transmission power adjusted in DCI, at this time, it may be necessary to define More bit number, and define the corresponding specific performance number of different bit informations.For example, 4 bit informations can be defined for referring to Show uplink maximum transmission power adjusted, such as 1000 instruction 8dB, 1010 instruction 10dB, 1110 instruction 14dB, 1111 represent 15dB, etc..
So, if uplink maximum transmission power adjusted is 10dB, in DCI can with bit information " 1010 " come Indicate uplink maximum transmission power adjusted.
It should be noted that after base station sends instruction information to terminal, it can be with instruction terminal in the corresponding upstream data of DCI The uplink maximum transmission power in NR system is adjusted according to power adjustment parameters in transmission time slot, i.e., uplink adjusted Maximum transmission power is only applied to the corresponding transmitting uplink data time slot of DCI.
Alternatively, instruction information can also indicate that terminal always sends out the uplink maximum in NR system according to power adjustment parameters Power is penetrated to be adjusted.For example, the uplink emission maximum all effective or adjusted before the new power adjustment parameters of determination Power continuously effective, etc..Those skilled in the art can be configured according to demand, and the embodiment of the present invention is not made this specifically Limitation.
In the embodiment of the present invention, indicate that information includes in independent information field, or instruction information reuse DCI in DCI Transmission power control (transmit power contr, TPC) information field.
If indicating the TPC information field in information reuse DCI, TPC letter can be indicated in DCI by 1 bit information of addition Ceasing domain is the actual uplink transmission power for adjusting terminal or the uplink maximum transmission power for adjusting terminal.If The 1 bit information instruction TPC information field added in DCI is the actual uplink transmission power for adjusting terminal, i.e., using side The realization of formula one adjusts uplink transmission power in the terminal, if 1 bit information indicates the uplink emission maximum function for adjusting terminal The realization of rate, i.e. employing mode two adjusts uplink transmission power in the terminal.
In the embodiment of the present invention, by the adjustment of the uplink maximum transmission power to terminal in NR system, realize to end The control of the uplink transmission power at end guarantees that existing power control scheme is unaffected in LTE system, while has terminal more Effect is transmitted using uplink transmission power, improves the upstream performance in NR system.
It should be noted that the solution of the present invention is not limited only to NR system and LTE system carries out the scene of dual link transmission, It can also be applied to carry out the scene of dual link transmission, such as NR and GSM, NR and TD-SCDMA etc. between other systems.
Below by the application scenarios for illustrating the present invention embodiment.
Firstly, base station is led to respectively by way of being semi-statically configured in the case where NR system and LTE system carry out dual link transmission Know maximum transmission power P of the terminal in NR system and LTE systemCmax, NRAnd PCmax, LTE。
Then, base station receives terminal and reports information, and is according to power headroom of the determining terminal in NR system of above notifying PHNR=PCmax, NR- P1, and, determine terminal LTE system power headroom be PHLTE=PCmax, LTE-P2。
Meanwhile base station according to report information determine terminal upstream data in NR system cache size be a bit, wherein The PUSCH transmission of UCI user class identifier (User Class Identifier, UCI) information and a2 bit comprising a1 bit Information, the cache size of upstream data is b bit in LTE system, and corresponding is PUSCH transmission information.If the power of UCI information The P of weight coefficient, the weight coefficient of PUSCH transmission information are Q, then the cache size that the terminal that base station obtains reports in NR system is X=a1*P+a2*Q, the buffer status information value reported in LTE system are Y=b*Q.
After base station obtains power headroom and cache size, the power headroom threshold value A and a LTE of a NR system can be set The power headroom threshold value B of system, when in the LTE system that the power headroom in the NR system that terminal reports is less than A and terminal reports Power headroom be greater than B when, then the buffer status in LTE system and NR system is compared in base station.
If data cached cache size is A ' in the NR system that terminal reports, data cached cache size is in LTE system B ', then as A ' > B ', then notice terminal in base station increases the uplink maximum transmission power of NR system.
Then, base station can dynamically indicate that uplink adjusted is most in NR system by 2 bit informations for including in DCI Difference between big transmission power and current maximum transmission power.For example, if dispatching PUSCH transmission information in NR system DCI in by 2 bit informations (such as 10) indicate that dynamic power adjustment can be with instruction terminal according to tune then in NR system The bit information " 10 " spent in the DCI of PUSCH transmission determines that power adjustment parameters are 1dB, then after terminal adjusts in NR system Uplink maximum transmission power be PCmax, NR+1dB。
Alternatively, if when the power in the LTE system that the power headroom in the NR system that terminal reports is greater than A and terminal reports When surplus is less than B, if A ' < B ', base station can also reduce the uplink maximum transmission power of NR system.
In the embodiment of the present invention, since base station exists to terminal by sending power configuration information to the terminal in dual link Uplink maximum transmission power in NR system and in LTE system is configured respectively, and then by notifying in acquisition terminal The use state for determining uplink transmission power of the terminal in the NR system and the LTE system is ceased, is determined for terminal Power adjustment parameters with the adjustment in dual link is transmitted to the uplink maximum transmission power in NR system, while can guarantee Existing power control scheme is unaffected in LTE system, to rationally utilize the uplink transmission power of terminal, improves NR system Upstream performance in system.

As shown in figure 3, the embodiment of the present invention provides a kind of ascending power control method, the terminal and wireless communication system NR And long evolving system LTE carries out dual link, the network architecture locating for the terminal may refer to Fig. 1.This method can describe such as Under:
S51: terminal receives the semi-static power configuration information that base station is sent, and according to power configuration information to NR system And the uplink maximum transmission power in LTE system is configured；
S52: terminal sends to base station and reports information；Wherein, report information for characterizing in NR system and LTE system The use state of row transmission power；
S53: terminal receives base station according to the instruction information for reporting information to feed back, and according to instruction information adjustment in NR system In uplink maximum transmission power, instruction information be Downlink Control Information DCI or high-level signaling.
In the embodiment of the present invention, power configuration information can be base station and notify terminal by way of being semi-statically configured, To be configured to uplink maximum transmission power of the terminal in NR and LTE system.
Wherein, uplink maximum hair of the terminal in NR system and in LTE system can be indicated in power configuration information The proportionality coefficient for penetrating the uplink maximum transmission power of power or terminal in NR system and in LTE system, that is, indicate Uplink maximum transmission power in NR system and LTE system distinguishes the ratio of the total uplink maximum transmission power of occupied terminal.
So, according to the difference of parameter entrained in power configuration information, terminal is according to power configuration information to NR system The process that uplink maximum transmission power in system and LTE system is configured may include but be not limited only to following two method:
Method 1: terminal is sent out according to uplink maximum of the terminal indicated in power configuration information in NR system and LTE system Power is penetrated to be configured.Uplink maximum transmission power i.e. directly according to configurating terminal in power configuration information in NR system, Such as PCmax, NRAnd uplink maximum transmission power of the configurating terminal in LTE system, such as PCmax, LTE。
Method 2: terminal is adjusted according to the proportionality coefficient of power uplink maximum transmission power in NR system and LTE system Uplink maximum transmission power.
For example, if the proportionality coefficient of the uplink maximum transmission power configured in power configuration information is LNR: LLTE=2:3, such as The total uplink maximum transmission power of fruit terminal is 200mW, then terminal can adjust the uplink maximum transmission power in NR system For PCmax, NRUplink maximum transmission power in LTE system can be adjusted to P by=80mW and terminalCmax, NR=120mW.
In S52, reporting information may include uplink maximum transmission power and reality of the terminal in NR system and LTE system Border uplink transmission power determines the current corresponding power headroom in NR system and LTE system, and/or, it is to be transmitted in terminal on The state parameter of row data, the state parameter can be used for characterizing terminal and emit when transmitting upstream data to be transmitted uplink The desirability of power.
State parameter may include cache size and/or QCI requirements, and cache size can be used for characterizing upstream data to be transmitted Buffer memory, QCI can be used for characterizing the importance of upstream data to be transmitted.
In practical applications, the upstream data of different service types can have different weight coefficients.For example, to higher Biggish weight coefficient value is arranged in the upstream data of the type of service of QCI demand.And cache size can be according to weight coefficient Value (such as x) and the buffer memory of the upstream data of each type of service (as b) determine report state parameter.
For example, if upstream data corresponds to k kind type of service, and the upper line number of each type of service in upstream data According to weight coefficient and buffer memory is corresponding with, then the cache size in state parameter can be x1*b1+x2*b2+ ...+xk*bk.Its In, when x*b represents the upstream data for transmitting a kind of type of service, desirability of the terminal to uplink transmission power.Usually, The uplink transmission power that the more big then GC group connector of cache size needs is bigger.
Then terminal can report after the state parameter for determining power headroom and/upstream data to be transmitted to base station.
In S53, the received instruction information of terminal can be DCI or high-level signaling (such as MAC CE).It is taken in indication signaling The power contorl parameters of band can be between uplink maximum transmission power and current uplink maximum transmission power after adjustment Difference, alternatively, being also possible to directly indicate uplink maximum transmission power adjusted.So, terminal is according to instruction information The uplink maximum transmission power of NR system and/or LTE system can be adjusted.
In the embodiment of the present invention, indicate that information includes in independent information field, or instruction information reuse DCI in DCI Transmission power control (transmit power contr, TPC) information field.
If indicating the TPC information field in information reuse DCI, TPC letter can be indicated in DCI by 1 bit information of addition Breath domain is the actual uplink transmission power for adjusting terminal or the uplink maximum transmission power for adjusting terminal, because This, terminal can rapidly be known according to TPC information adjusts targeted object.
In practical applications, if instruction information is DCI, the power tune in adjustment, in terminal DCI available first Whole parameter, so it is maximum to the uplink in NR system according to power adjustment parameters in the corresponding transmitting uplink data time slot of DCI Transmission power is adjusted, i.e., uplink maximum transmission power adjusted is only applied to the corresponding transmitting uplink data time slot of DCI. Alternatively, terminal can also always be adjusted the uplink maximum transmission power in NR system according to power adjustment parameters, such as should Power contorl parameters before the new power adjustment parameters of determination all effectively or uplink maximum transmission power adjusted always Effectively, etc..
In the embodiment of the present invention, terminal can be according to the semi-static power configuration information in base station to NR system and LTE system In uplink maximum transmission power configured, in turn, by calculating power headroom in each system and upper line number to be sent According to state parameter obtain base station according to the power for reporting information feedback and by power headroom and/or state parameter reporting base station Adjusting parameter realizes the adjustment to the uplink transmission power in each system according to power adjustment parameters, improves terminal in dual link To the reasonable utilization of uplink power in transmission.

Then terminal is after receiving power configuration information, can according to the shared power headroom that base station notifies proportionality coefficient into Dump power between row NR system and LTE system it is shared.
So, the minimum guarantee power according to terminal in NR system and LTE system and the in proportion shared uplink of coefficient Transmission power can determine uplink maximum transmission power of the terminal in each system, i.e. terminal is adjusted in LTE system Uplink maximum transmission power is that minimum guarantee transmission power of the terminal in LTE system adds power headroom multiplied by corresponding ratio Coefficient, adjusted uplink maximum transmission power of the terminal in NR system are minimum guarantee transmitting function of the terminal in NR system Rate is plus power headroom multiplied by corresponding proportionality coefficient.
For example, the proportionality coefficient of the shared power headroom in power configuration information is LNR: LLTE=0.4:0.6, present terminal Power headroom be PIt is remaining, then sendout of the power headroom of terminal in NR system is known are as follows: PNR=0.4PIt is remaining, the power of terminal Sendout of the surplus in LTE system are as follows: PLTE=0.6PIt is remaining。
So, base station match by uplink power of the power configuration information to terminal and postpone, it is known that terminal is in NR system In uplink maximum transmission power, it is shared with coefficient in proportion which is actual uplink transmission power The sum of power headroom.In the case where power limited, actual uplink transmission power can be equal to minimum guarantee transmission power.Cause This, uplink maximum transmission power of the terminal in NR system is PCmax, NR=PCmin, NR+0.4PIt is remaining, terminal is upper in NR system Row maximum transmission power is PCmax, NR=PCmin, NR+0.6PIt is remaining。
In the embodiment of the present invention, base station does not need the information that reports of terminal, terminal can in the case where power limited ability root Power adjustment is carried out according to the configuration of base station, implementation is more convenient, is conducive to the utilization for improving the uplink power of terminal.
