Description

The outer-loop power controlling method of ascending reinforced special channel
Technical field
The present invention relates to 3G (Third Generation) Moblie, particularly about among the E-DCH, method for controlling up link external ring power.
Background technology
Second generation mobile communication system comprises GSM (Global System for MobileCommunications) and IS (Interim Standard)-95, and main target provides voice service.GSM has adopted the TDMA technology, in commercialization in 1992, is mainly used in Europe and China.And IS-95 adopts is CDMA (Code Division Multiple Access), is mainly used in the U.S. and Korea S.
At present, mobile communication technology has been evolved to 3-G (Generation Three mobile communication system), except voice service is provided, also provides two-forty and high-quality data service and multimedia service.3-G (Generation Three mobile communication system) comprises that the asynchronous CDMA system of 3GPP International Standards Organization research (or claims the WCDMA system, or title UMTS), be that timing between each base station is asynchronous, with the synchronous CDMA system (or claiming CDMA2000) of 3GPP2 International Standards Organization research, i.e. timing between each base station is identical.
Synchronous and asynchronous 3-G (Generation Three mobile communication system) is all to providing two-forty, high-quality data packet services to carry out standardization.For example: 3GPP is carrying out standardization to HSDPA (being called for short high-speed downstream inserts), thereby improves descending data rate, and 3GPP2 is carrying out standardization to 1xEV-DV (Evolution-Data and Voice).3GPP proceeds the enhancing (E-DCH) of ascending packet data transmission again, thereby improves up capacity and covering.E-DCH compares with the up DCH of Rel99/4/5, and scheduling feature is moved on to Node B from RNC, to realize fast dispatch; Introduced HARQ (Hybrid Automatic Retransmission Request) mechanism, retransmitted in physical layer.
After introducing E-DCH, the kind of physical channel as shown in Figure 7.Comprise 701 Dedicated Physical Control Channels (DPCCH) among the Rel99,702 Dedicated Physical Data Channels (DPDCH), be used for the ascending control channel HS-DPCCH of HSDPA with 705 among the Rel5, and 703 behind the introducing ascending reinforced special channel strengthens Dedicated Physical Data Channel (E-DPDCH), be used to transmit the E-DCH data, with 704 enhancing Dedicated Physical Control Channels (E-DPCCH), be used to transmit the control information that is used for E-DPDCH decoding, as E-TF (E-DCH transformat), schedule information, HARQ information (as receive sequence number RSN) etc.E-DCH and DCH are present among two coded combination transmission channel CcTrCH.
In the WCDMA of Rel99 system, adopted the exterior ring power controlling mechanism.Its objective is communication quality is remained on the target value set.If communication quality is too high, can waste Radio Resource; Communication quality is low excessively, does not reach communicating requirement.So the effect of exterior ring power control is exactly to make communication quality keep stable by suitable target signal to noise ratio (SIR target) is set to rapid power control.Under different channel conditions, in order to reach certain target Block Error Rate (BLER target), target signal to noise ratio (SIR target) is different.Target signal to noise ratio (SIR target) and actual signal to noise ratio (SIR) that the rapid power control of interior ring is set according to external circule power control compare, and finish inner-loop power control.Adjusting frequency of exterior ring power control is 10～100Hz.
Be controlled to be example with ascending exterior ring power, RNC can be after grand diversity, the up quality of reception is estimated, when the quality of reception is better than target call, RNC can reduce SIR target, when the quality of reception was lower than target call, RNC can improve SIR target, and passed to Node B by high-level signaling.Estimate at several different methods for up quality, as: based on the block error rate BLER result of CRC detection, or transmission channel bit error rate (TrCH BER), or physical channel bit error rate (physicai channelBER), or SIR, or Eb/NO, or other method.
In Rel99, for the situation of up multiple business, multiple business is multiplexed on the coded combination transmission channel (CcTrCH).Because multiple business has a public rapid power control, so only corresponding public SIR target, this SIR target is that RNC estimates the up quality of reception of every kind of business, requires the highest business to determine SIR target according to SIR target.Because the employing of non-uniform speed coupling, the SIR target between the multiple business does not have very big gap.The method of operation of the exterior ring power control under the multiple business and the situation of depositing as shown in Figure 1, has been described among the Rel99.
In Rel99, the DPDCH/DPCCH power offset is relevant with the TFC that DPDCH uses, and detailed calculated can save with reference to 36PP TS25.214 5.1.2.5.In the present invention, the DPDCH/DPCCH power offset is meant the dB value of DPDCH power and the ratio of DPCCH power, i.e. DPDCH/DPCCH power offset (dB)=10*log 10(DPDCH power (milliwatt)/DPCCH power (milliwatt)).The E-DPDCH/DPCCH power offset is meant the dB value of E-DPDCH power and the ratio of DPCCH power, i.e. E-DPDCH/DPCCH power offset (dB)=10*log 10(E-DPDCH power (milliwatt)/DPCCH power (milliwatt)).The E-DPCCH/DPCCH power offset is meant the dB value of E-DPCCH power and the ratio of DPCCH power, i.e. E-DPCCH/DPCCH power offset (dB)=10*log 10(E-DPCCH power (milliwatt)/DPCCH power (milliwatt)).This definition is applicable to the description of back.
Owing to introduced up enhancing exclusive use transmission signal channel, the E-DCH transmission channel may exist simultaneously with dedicated transmission channel DCH, and E-DCH is carried to respectively on the different CcTrCH with DCH, carries out code division multiplexing.Because E-DCH and DCH use same fast power control procedure, thereby E-DCH and DCH need be carried out exterior ring power control by common SIR target.But because the different qualities of E-DCH and DCH channel, such as: E-DCH and DCH are owing to carrying different business (for example: E-DCH carries Packet Service, DCH voice-over business), so the QoS difference; E-DCH has physical layer retransmission mechanism, and DCH does not have; E-DCH is different with the coding strand of DCH; The TTI of E-DCH and DCH can be different; The effect difference of grand diversity, these differences cause the needed SIRtarget of E-DCH and DCH also different.
Different with Rel99 is the difference that E-DCH and DCH can't dwindle SIRtarget by rate-matched heterogeneous, so the difference of SIR target may be bigger.If the quality of reception and qos requirement according to one of them channel are provided with SIR target, may cause the quality of reception of one other channel not meet the demands.If perhaps, SIR target is set, then may causes another to require lower channel to launch, thereby cause bigger uplink interference with unnecessary big power to SIR target according to the higher business of SIR target according to the principle of Rel99.Therefore being necessary to introduce method of the present invention compensates the difference of the SIR target of E-DCH and DCH.
Summary of the invention
The method that the purpose of this invention is to provide the control of ascending exterior ring power among a kind of E-DCH when making SIR target as E-DCH and DCH different, compensates the through-put power of E-DPDCH.

201:Node B measures the up quality of reception and reports to RNC, comprises the up quality of reception of DCH and the up quality of reception of E-DCH;
202:RNC is provided with the target signal to noise ratio (SIR target) of exterior ring power control according to the up quality of reception of DCH transmission channel;
203:RNC passes to Node B with target signal to noise ratio;
204:RNC is provided with an additional E-DPDCH/DPCCH power offset (additional E-DPDCH/DPCCH power offset) according to the QoS and the up quality of reception of E-DCH and DCH;
205:RNC will add E-DPDCH/DPCCH power offset (additional E-DPDCH/DPCCHpower offset) and pass to UE;
206:RNC will add E-DPDCH/DPCCH power offset (additional E-DPDCH/DPCCHpower offset) and pass to Node B;
207:UE decides the transmitted power of up E-DPDCH according to E-DPDCH/DPCCH power offset among the Rel99 and additional E-DPDCH/DPCCH power offset (additional E-DPDCH/DPCCH power offset), sends the E-DCH data.
In the present invention, RNC decides the target signal to noise ratio (SIR target) and the secondary power side-play amount of exterior ring power control, and can change E-DCH average transmission number of times by changing the additional offset amount.
The operation of RNC:
As shown in Figure 3.
301:RNC is provided with the target signal to noise ratio (SIR target) of exterior ring power control, its foundation is the up quality of reception of DCH transmission channel, when the up quality of reception is higher than desired value, SIR target will reduce, when the up quality of reception is lower than desired value, SIR target will improve, and RNC passes to Node B with the value of SIR target by the NBAP signaling then, and this process is the same with process among the Rel99.
302:RNC is provided with an additional E-DPDCH/DPCCH power offset (additional E-DPDCH/DPCCH power offset).Because being the up quality of reception according to DCH, the target signal to noise ratio (SIRtarget) of exterior ring power control is provided with, do not consider the quality of reception of E-DCH, so RNC is provided with an additional E-DPDCH/DPCCH power offset, its effect is compensate the SIR target of E-DCH and DCH poor.The setting of secondary power side-play amount is the quality of reception according to the QoS of E-DCH and DCH and up DCH and E-DCH.Because the variation of channel condition, the coding strand that DCH is different with E-DCH, different TTI, and the different gains of grand diversity, make the SIR target of E-DCH and DCH have variation, compensate the poor of SIRtarget so introduce additional E-DPDCH/DPCCH power offset.
303:RNC is with additional E-DPDCH/DPCCH power offset) pass to UE.Can pass through the RRC signaling, the FP signaling also can be passed through other method.
The transmission of additional E-DPDCH/DPCCH power offset can periodically send, and also can send in the Event triggered mode.
304:RNC will add E-DPDCH/DPCCH power offset (additional E-DPDCH/DPCCHpower offset) and pass to Node B.Its objective is and be used for Node B scheduling.
The operation of Node B:
401:Node B measures the up quality of reception and reports to RNC, comprises the up quality of reception of DCH and the up quality of reception of E-DCH.The up quality of reception can be a Block Error Rate, and promptly the CRC check result also can be a transmission channel bit error rate, physical channel bit error rate, SIR, perhaps Eb/NO.Also the E-DCH data transmission times can be reported to RNC.
402:Node B receives the target signal to noise ratio that RNC is provided with, and carries out up inner loop power control according to this target signal to noise ratio.
403:Node B receives the secondary power side-play amount from RNC, is used for estimating more accurately up ROT, thereby carries out Node B scheduling.
The operation of UE:
UE decides the transmitted power of up E-DPDCH according to E-DPDCH/DPCCH power offset among the Rel99 and additional E-DPDCH/DPCCH power offset (additional E-DPDCH/DPCCH power offset), sends the E-DCH data.
The present invention also is applicable to the situation of a plurality of DCH, when a plurality of DCH exist simultaneously, can be identical with the processing procedure of Rel99, require the highest DCH to determine the SIRtarget of external circule power control according to SIR target, and require the highest DCH and the SIR target of E-DCH to compare according to SIR target, determine to add the E-DPDCH/DPCCH power offset.
The present invention is not only applicable to the situation of non-soft handover (None SHO), also is applicable to the situation of soft handover (SHO).For the situation of soft handover, the setting of external circule power control SIR target is the result according to DCH after the grand diversity, and the setting of additional E-DPDCH/DPCCH power offset is according to the result of E-DCH after the grand diversity and the result of DCH.And under the situation of soft handover, RNC will pass to scheduling Node B with adding the E-DPDCH/DPCCH power offset, also can pass to non-scheduling Node B simultaneously.
The invention provides the method for ascending control channel exterior ring power control among a kind of E-DCH, as shown in Figure 8, comprise step:
801:RNC be provided with E-DPCCH/DPCCH power offset initial value and pass to UE;
802:RNC be provided with E-DPCCH/DPCCH power offset initial value and pass to Node B;
803:RNC calculates the power offset of the E-DPCCH/DPCCH that reconfigures;
The power offset that RNC reconfigures E-DPCCH/DPCCH can adopt following two kinds of methods:
A kind of method be can be directly according to the variation of the power offset of E-DPDCH/DPCCH, when RNC reconfigures additional E-DPDCH/DPCCH power offset, also reconfigure the power offset of E-DPCCH/DPCCH.
Whether another kind method is that RNC can reconfigure the power offset of E-DPCCH/DPCCH according to the E-DPCCH quality of reception supplementary that Node B provides, change and be independent of additional E-DPDCH/DPCCH power offset.
804:RNC passes to UE with the E-DPCCH/DPCCH power offset that reconfigures;
805:RNC passes to Node B with the E-DPCCH/DPCCH power offset that reconfigures;
806:UE calculates the E-DPCCH transmitted power according to the power offset of E-DPCCH/DPCCH, and sends E-DPCCH.
The operation of RNC:
At first, RNC be provided with E-DPCCH/DPCCH power offset initial value and pass to UE and Node B;
E-DPCCH is by E-DCH transformat (E-TF), receive sequence number (RSN), and fields such as schedule information are formed, because the performance requirement of these fields may be different with coded system, different field can be provided with the different power offset with respect to DPCCH.
Then, RNC calculates the power offset of the E-DPCCH/DPCCH that reconfigures;
When reconfiguring, the E-DPCCH different field can reconfigure the different power offset with respect to DPCCH.
RNC resets the power offset of E-DPCCH/DPCCH, first method can be directly according to the variation of the power offset of E-DPDCH/DPCCH.Because the decode results of E-DPDCH depends on the E-DCH transformat (E-TF) that carries among the E-DPCCH, receive sequence number information such as (RSN) is so the quality of reception of E-DPDCH also depends on the quality of reception of E-DPCCH.In order to guarantee the quality of reception of E-DPCCH, when additional E-DPDCH/DPCCH power offset changed, RNC can reset the power offset of E-DPCCH/DPCCH.
RNC resets the power offset of E-DPCCH/DPCCH, the E-DPCCH quality of reception supplementary that second method can provide according to Node B.
RNC passes to UE and Node B with the E-DPCCH/DPCCH power offset that reconfigures;
The operation of Node B:If what RNC reconfigured employing to the power offset of E-DPCCH/DPCCH is first method, promptly directly carry out according to the variation of the power offset of E-DPDCH, then Node B only need receive the corresponding information that UE and RNC send.
If what RNC reconfigured employing to the power offset of E-DPCCH/DPCCH is second method, promptly the E-DPCCH quality of reception supplementary that provides according to Node B of RNC is reset the power offset of E-DPCCH/DPCCH.In this case, Node B also will estimate the E-DPCCH quality, and the result is reported to RNC except needs receive the corresponding information that UE sends and RNC sends.
The operation of UE:
UE calculates the E-DPCCH transmitted power according to the power offset of E-DPCCH/DPCCH, and sends E-DPCCH.
Provide two embodiment of the present invention below.
Embodiment one: uplink data channels outer-loop power controlling method embodiment among the E-DCH
Node B measures the up quality of reception and reports to RNC, comprise the up quality of reception of DCH and the up quality of reception of E-DCH, the up quality of reception comprises DCH and E-DCH Block Error Rate, be the CRC check result, DCH and E-DCH transmission channel bit error rate also can report to RNC with the E-DCH data transmission times.
RNC is provided with the target signal to noise ratio (SIR target) of exterior ring power control according to the up quality of reception of DCH transmission channel, its foundation is the up quality of reception of DCH transmission channel, when the up quality of reception of DCH is higher than desired value, SIR target will reduce, when the up quality of reception of DCH is lower than desired value, SIR target will improve, and RNC passes to Node B with the value of SIR target by the NBAP signaling then, and this process is the same with process among the Rel99.
RNC passes to Node B with target signal to noise ratio.
RNC is provided with an additional E-DPDCH/DPCCH power offset (additional E-DPDCH/DPCCH power offset) according to the QoS and the up quality of reception of E-DCH and DCH.Concrete operations as shown in Figure 5.
The parameter of earlier Fig. 5 being used describes:
The SIR target of SIR_target_e:E-DCH transmission channel;
The SIR target of SIR_target_d:DCH transmission channel;
Delta_pre: a preceding E-DCH transmission channel and DCH transmission channel SIR target's is poor, and initial value is by network settings;
Delta_cur: current E-DCH transmission channel and DCH transmission channel SIR target's is poor;
APO: additional E-DPDCH/DPCCH power offset (additional E-DPDCH/DPCCH poweroffset), unit is dB;
The step-length that step_size:APO increases or reduces.
Set delta_pre, APO, the initial value of step_size according to step 501:RNC among Fig. 5.
For example: delta_pre=0, APO=OdB, step_size=0.1dB.
Calculate E-DCH and DCH SIR target separately according to step 502:RNC among Fig. 5 according to the up quality of reception of Node B report and the QoS of E-DCH and DCH, be SIR_target_e and SIR_target_d, the same Rel99 of method is in front to having description in 201 the explanation.
According to step 503:RNC among Fig. 5 calculate current E-DCH transmission channel and the poor delta_cur of DCH transmission channel SIR target,
delta_cur＝SIR_target_e-SIR_target_d。
Poor greater than a preceding E-DCH transmission channel and DCH transmission channel SIR target whether according to the difference of more current E-DCH transmission channel of step 504:RNC among Fig. 5 and DCH transmission channel SIRtarget.
If comparative result be greater than, then execution in step 505: additional E-DPDCH/DPCCH power offset APO increases a step_size,
If comparative result be less than, then execution in step 506: additional E-DPDCH/DPCCH power offset APO reduces by a step_size.
Then, the difference with current E-DCH transmission channel and DCH transmission channel SIR target is changed to the poor of a preceding E-DCH transmission channel and DCH transmission channel SIR target.
At last, return step 502, carry out computational process next time.
RNC will add E-DPDCH/DPCCH power offset (additional E-DPDCH/DPCCHpower offset) and pass to UE and Node B;
UE decides the transmitted power of up E-DPDCH according to E-DPDCH/DPCCH power offset among the Rel99 and additional E-DPDCH/DPCCH power offset (additional E-DPDCH/DPCCH power offset).Concrete operations as shown in Figure 6.
E-DPDCH is not only relevant with the transformat that uses with the ratio of DPCCH power, and is also relevant with 602 additional E-DPDCH/DPCCH power offset APO.The gain factor relevant with 602 additional E-DPDCH/DPCCH power offset APO with 603 transformats is designated as 604 β EU, β EU=f (APO, E_TF);
Similar to the computational methods of the ratio of DPCCH power to DPDCH among the Rel99, the ratio of E-DPDCH and DPCCH power is relevant with the transformat of use, and the E-DPDCH/DPCCH gain factor relevant with transformat is designated as β EU2, β EU2=g (E_TF);
The E-DPDCH/DPCCH gain factor relevant with additional E-DPDCH/DPCCH power offset APO is designated as β EU1,
β EU 1 = 10 ( APO 20 ) ;
β then EU=β cβ EU1β EU2
Wherein, β CIt is the gain factor of DPCCH.
β EU/ β cBe the power ratio of E-DPDCH/DPCCH, the power of DPCCH is to be subjected to the effect of fast power control and to change, and the power of E-DPDCH can calculate according to the power of DPCCH and the power ratio of E-DPDCH/DPCCH.
Embodiment two: among the E-DCH ascending control channel outer-loop power controlling method embodiment RNC be provided with E-DPCCH/DPCCH power offset initial value and pass to UE and Node B.RNC reconfigures the power offset of E-DPCCH/DPCCH.
RNC resets the power offset of E-DPCCH/DPCCH, can be according to the variation of the power offset of E-DPDCH/DPCCH.When additional E-DPDCH/DPCCH power offset increase, the power offset of E-DPCCH/DPCCH also increases; When additional E-DPDCH/DPCCH power offset reduction, the power offset of E-DPCCH/DPCCH remains unchanged or reduces.In order to guarantee the quality of E-DPCCH, the speed that the power offset of E-DPCCH/DPCCH reduces will be lower than the speed of increase.It is fairly simple that this method is adjusted the power offset of E-DPCCH/DPCCH, do not need Node B that the E-DPCCH quality is estimated and report.
In order to make RNC that the E-DPCCH/DPCCH power offset can be set accurately, when RNC resets the power offset of E-DPCCH/DPCCH, the also E-DPCCH quality of reception supplementary that can provide according to Node B.When RNC finds that the quality of E-DPCCH is lower than the threshold value of setting, then the E-DPCCH/DPCCH power offset will increase, thereby strengthen the quality of reception of E-DPCCH.
RNC passes to UE and Node B with the E-DPCCH/DPCCH power offset that reconfigures; At last, UE calculates the E-DPCCH transmitted power according to the power offset of E-DPCCH/DPCCH, and sends E-DPCCH.
