The invention also discloses a downlink united power control method. The probability of open loop power control can be reduced as much as possible by the methods, so that the strong interference of open loop power to other channels can be lowered furthest, and the power control performance can be improved.
Description
Technical field
The present invention relates to the power control techniques in communication system, particularly up associating power control and the descending associating circule power control method in a kind of high-speed packet access (HSPA).
Background technology
In the TD-SCDMA system, can improve the throughput of uplink and downlink data by introducing HSUPA and HSDPA technology.
In TD-SCDMA agreement and high-speed packet evolution (HSPA+) agreement, up channel E-PUCH, E-RUCCH, HS-SICH, DPCH carry out independently uplink power control separately, various ways concurrent maintenance uplink power control separately.
Particularly, uplink power control process for E-PUCH is: network is controlled (RRC) module by Radio Resource and is configured expectation received power to UE, be used for the open loop power setting (open loop Pebase) of E-PUCH, the TPC command word that E-PUCH sends by NodeB on the expectation received power basis of initial configuration is dynamically adjusted the P of UE
E-baseCarry out closed-loop power control, make all UE can keep the benchmark code check expectation received power P identical with NodeB
E-baseUE safeguards the closed loop GAP of E-PUCH, if the GAP counting is not overtime, UE is with the P of current maintenance
E-baseFor benchmark arranges transmitting power; If GAP counting is overtime, UE arranges transmitting power take the expectation received power (open loop Pebase) of RRC configuration as benchmark.
Wherein, in the uplink closed-loop power control process of E-PUCH, NodeB compares according to the E-PUCH signal power and the default thresholding that receive, determines to raise or reduce the E-PUCH transmitting power, thereby determines and issue the TPC order by E-AGCH or E-HICH to UE; UE according to the TPC order that receives to P
E-baseAdjust, after " up " order of receiving TPC, P
E-baseIncrease Δ e-base on the basis of original numerical value, after " down " order of receiving TPC, P
E-baseReduce Δ e-base on the basis of original numerical value.The size of Δ e-base value is configured by high level, is upgrading P
E-baseAfter, the transmitted power that UE calculates E-PUCH is: P
E-PUCH=P
E-base+ L+ β
e, wherein, L is circuit loss value, β
eE-PUCH power adjustment for the relative datum code check.
Uplink power control process for HS-SICH is: network is used for the open loop power setting of HS-SICH to the expectation received power of UE configuration HS-SICH by RRC.The TPC command word that HS-SICH carries according to HS-SCCH or HS-PDSCH on the expectation received power basis of initial configuration is adjusted the HS-SICH transmitting power and is carried out closed-loop power control.UE safeguards the closed loop GAP of HS-SICH, if the GAP counting is not overtime, UE arranges transmitting power with the closed power of current maintenance; If GAP counting is overtime, UE arranges transmitting power take the HS-SICH expectation received power of RRC configuration as benchmark.
Uplink power control process for E-RUCCH is: NodeB arranges the power mandate of E-RUCCH, and sends to UE by FPACH take the open loop power of SYNC UL as reference.The open loop power of SYNC UL is notified UE by network by high-level signaling.
Uplink power control process for DPCH is: NodeB remains that to DPCH a transmission code rate carries out closed-loop power control, in this closed-loop power control process, only take the target SIR of this DPCH as the basis, determine the TPC order, carry out the power adjustment, and do not consider the interference and the impact on making an uproar at the bottom of equipment and causing that cause for other channels.
As previously mentioned, for E-PUCH, HS-SICH, DPCH and four up channels of E-RUCCH, carry out separately independently power control, on the one hand, network and UE safeguard the independently power control separately of four channels, control procedure more complicated; On the other hand, the open loop power value of E-PUCH and HS-SICH is usually larger, thereby cause other up channels with carrier wave are formed larger uplink interference, especially when HS-SICH and the synchronic gap of E-PUCH, both in the up open loop power of arbitrary channel all can cause strong jamming to the other side's channel.
In TD-SCDMA agreement and high-speed packet evolution (HSPA+) agreement, down channel HS-SCCH and E-AGCH carry out independently downlink power control separately.The secondary spreading code of E-HICH does not carry out downlink power control.
Particularly, the uplink power control process for HS-SCCH is: the expectation received power of network configuration HS-SCCH is used for the open loop power setting of HS-SICH.HS-SCCH adjusts the HS-SICH transmitting power according to the TPC command word of UE feedback and carries out closed-loop power control on the expectation received power basis of initial configuration.The closed loop GAP of network operation HS-SCCH, if the GAP counting is not overtime, NodeB is according to the closed power of current maintenance, according to TPC command set transmitting power; If GAP counting is overtime, NodeB arranges transmitting power take the HS-SCCH expectation received power of network configuration as benchmark.Wherein, UE determines and the mode of feeding back the TPC order is: UE controls thresholding according to the HS-SCCH that receives with default power and compares, if greater than this thresholding, generates and falls lower powered TPC order, if less than this thresholding, high-power TPC order is proposed in generation.
For the uplink power control process of E-AGCH and the uplink power control similar process of above-mentioned HS-SCCH, the open loop power of the E-AGCH that just arranges and GAP value can be different.Here just repeat no more.Above-mentioned two channels carry out downlink power control independently of one another.
The E-HICH channel is used for carrying the downstream signal of a plurality of UE, and wherein, the E-HICH signal of each UE can utilize different secondary spreading codes to carry out the secondary spread spectrum, forms E-HICH secondary spreading code.For the E-HICH secondary spreading code of any UE, in the TD-SCDMA agreement, utilize semi-continuous E-PUCH to carry its corresponding TPC order, but, this TPC order is filled at random by UE, after NodeB receives this TPC order, also can not carry out downlink power control to E-HICH secondary spreading code.That is to say, NodeB does not carry out downlink power control to the E-HICH secondary spreading code of UE at present.This just makes UE after receiving E-HICH secondary spreading code, only can detect the situation of its signal strength signal intensity, but due to the intensity that can't know the NodeB transmitted signal, therefore, can't determine the current downlink channel quality.

Embodiment
For making purpose of the present invention, technological means and advantage clearer, below in conjunction with accompanying drawing, the present invention is described in further details.
For the different channels on same carrier wave, its wireless channel environment can be thought identical, therefore, for reaching the receptivity of system requirements, the difference on same carrier wave between the different channels expectation received power, often relatively fixing.Based on this, basic thought of the present invention is: for a plurality of up channels on same carrier wave, utilize mutual relatively-stationary expectation received power difference, take the transmitting power of other up channels as the basis, calculate the transmitting power of a certain up channel, utilize the signal that open loop power carries out to send thereby reduce as far as possible, reduce strong jamming to each other.In like manner, for a plurality of down channels on same carrier wave, utilize mutual relatively-stationary expectation received power difference, take the transmitting power of other down channels as the basis, calculate the transmitting power of a certain down channel.
Next, uplink and downlink associating circule power control method provided by the invention is described in detail respectively.
Embodiment one:
In up associating circule power control method, the first implementation is: a plurality of up channels with carrier wave are shared P
E-base, the closed-loop power control GAP that each channel is safeguarded unity carries out up associating power control.Wherein each up channel adopts with the similar mode of E-PUCH and carries out closed-loop power control, namely upgrades according to the TPC order that receives and shares P
E-base, and the P to share
E-baseFor determining transmitting power in the basis.
In the present embodiment, to carry out up associating power control with carrier wave E-PUCH, HS-SICH, DPCH and E-RUCCH.In addition, because present NodeB is all that channel to each user carries out respectively power and controls, therefore, in the present invention, carry out the associating power control for each up channel on same carrier wave that belongs to same user.In the following description, as without special suggestion, E-PUCH, HS-SICH, DPCH and E-RUCCH all refer to the respective channel of same user on same carrier wave.Concrete circule power control method flow process comprises as shown in Figure 1:
Step 101 sets in advance E-PUCH power adjustment corresponding to the multiple transmission code rate of E-DCH and HS-SICH, DPCH and E-RUCCH with respect to the power adjustment of E-DCH benchmark code check, and notice UE.
In existing E-PUCH closed-loop power control, can the power adjustment of E-PUCH be set for multiple transmission code rate, this is due to the P in the E-PUCH closed-loop power control
E-baseIt is the expectation received power of benchmark code check, and for different E-DCH code checks, there is certain difference between the expectation received power of its expectation received power and benchmark code check, utilizing power adjustment to represent difference between the expectation received power of expectation received power and benchmark code check under different E-DCH code checks, is also the β in aforementioned background art
eUsually, in existing E-PUCH closed-loop power control, utilize a mapping table to preserve multiple E-DCH code check and corresponding E-PUCH power adjustment thereof, when carrying out actual power control, can utilize the content of this mapping table, in conjunction with current E-DCH code check, determine the E-PUCH power adjustment β that current E-DCH code check is corresponding
e, for the transmitting power of calculating E-PUCH.
In the present invention, at first same as the prior artly, E-PUCH power adjustment corresponding to multiple E-DCH transmission code rate is set, further, HS-SICH is set with respect to the power adjustment β of E-DCH benchmark code check
λ 1, DPCH is with respect to the power adjustment β of E-DCH benchmark code check
λ 2With E-RUCCH power adjustment β
λ 3
Wherein, HS-SICH is with respect to the power adjustment β of E-DCH benchmark code check
λ 1Set-up mode can for: the E-PUCH of E-DCH benchmark code check transmission and HS-SICH are transmitted carry out emulation in advance, be defined as reaching the receptivity of system requirements, expectation received power between E-PUCH and HS-SICH is poor, according to this difference power, HS-SICH is set with respect to E-DCH benchmark code check power adjustment.For example, the E-PUCH transmission under E-DCH benchmark code check and the difference power between the HS-SICH transmission are 2dB, and HS-SICH is E-PUCH power adjustment β corresponding to E-DCH benchmark code check with respect to the power adjustment of E-DCH benchmark code check
e-2dB.Here it should be noted that: each power adjustment that sets in advance is the analog value that obtains under the code channel of SF=16.
DPCH is with respect to the power adjustment β of E-DCH benchmark code check
λ 2And β
λ 3Set-up mode and above-mentioned β
λ 1Set-up mode identical, namely emulation is carried out in E-PUCH transmission and DPCH, the transmission of E-DCH benchmark code check, the expectation received power between determining both is poor, thereby corresponding β is set
λ 2β
λ 3Setting in like manner.
Notify UE with each power adjustment of above-mentioned setting by the mode of RRC signaling or default value.
In the present embodiment, E-PUCH, HS-SICH, DPCH and E-RUCCH share the expectation received power P of benchmark code check
E-base, to should P
E-baseClosed-loop power control GAP is set, and therefore, the closed-loop power control GAP of E-PUCH, HS-SICH and E-RUCCH is identical.
Step 103 is according to unified closed-loop power control GAP and shared P
E-base, according to existing mode, E-PUCH is carried out power and controls.
Wherein, when determining the transmitting power of E-PUCH, at first determine the TPC order corresponding to this E-PUCH, determine that specifically mode is with existing identical; Then, judge whether unified closed-loop power control GAP is overtime, judgment mode is with existing identical; If not overtime, upgrade according to the TPC order of determining the current P that shares
E-base, then according to the P after upgrading
E-baseCalculate transmitting power according to existing mode; If overtime, determine transmitting power according to existing mode by open loop.
In above-mentioned power control process to E-PUCH, the P that E-PUCH upgrades
E-baseAfter may being upgraded by other up channels (HS-SICH or DPCH), thereby realize for P
E-baseShare.Than the power control mode of existing E-PUCH, because closed-loop power control GAP is corresponding to P
E-base, and P
E-baseBe that E-PUCH, HS-SICH, DPCH and E-RUCCH share, even therefore last time, the E-PUCH transmission exceeded closed-loop power control GAP with the time interval that this E-PUCH transmits, as long as in closed-loop power control GAP, have HS-SICH and DPCH to safeguard P
E-base, E-PUCH still can carry out closed-loop power control.Therefore, greatly increased and carried out the probability of closed-loop power control, thereby reduced due to open loop power control the strong jamming of other channels.
Step 104 is for HS-SICH, according to unified closed-loop power control GAP and shared P
E-base, carry out joint Power and control.
In the present embodiment, determine to carry out open loop power control according to unified closed-loop power control GAP and still carry out closed-loop power control.And when HS-SICH was carried out closed-loop power control, the TPC instruction of carrying according to HS-SCCH or HS-PDSCH was to the P that shares
E-baseUpgrade, and utilize the β that arranges in step 101
λ 1Determine that this HS-SICH is with respect to the power adjustment β of E-DCH benchmark code check
HS-SICH, then according to β
HS-SICHWith the P after renewal
E-base, the transmitting power P of calculating HS-SICH
HS-SICH=P
E-base+ L+ β
HS-SICH, wherein, L is circuit loss value.
Wherein, because the HS-SICH that distributes to UE may take many code channels, and the β that arranges in step 101
λ 1Be a corresponding power adjustment of SF=16 code channel, but along with the increasing of code channel number, power adjustment should increase to some extent, therefore, here, need to be according to the β that arranges
λ 1With the actual code channel number that takies of the HS-SICH that distributes to UE, determine that the HS-SICH of this distribution is with respect to the power adjustment β of E-DCH benchmark code check
HS-SICHFor example, the code channel of a SF=16 of every increase is with β
λ 1Increase 3dB, as β
HS-SICH
As seen by above-mentioned, in fact, in the present embodiment, the closed-loop power control mode of the closed-loop power control mode of HS-SICH and E-PUCH is similar, utilizes P
E-baseAnd β
HS-SICHCalculate the transmitting power of HS-SICH.In this account form, due to power adjustment β
HS-SICHBe to determine according to the difference power of E-PUCH and HS-SICH emulation, therefore, utilize the transmitting power that this mode obtains to be complementary with the expectation received power of HS-SICH, can realize good power control performance.Simultaneously, this power control mode and above-mentioned E-PUCH power control can reduce the probability that HS-SICH carries out open loop power control, thereby reduce due to open loop power control the strong jamming of other channels similarly.
Step 105 is for DPCH, according to unified closed-loop power control GAP and shared P
E-base, carry out joint Power and control.
In the present embodiment, determine to carry out open loop power control according to unified closed-loop power control GAP and still carry out closed-loop power control.And, when DPCH is carried out closed-loop power control, according to the TPC instruction, to the P that shares
E-baseUpgrade, and utilize the β that arranges in step 101
λ 2Determine that this DPCH is with respect to the power adjustment β of E-DCH benchmark code check
DPCH, then according to β
DPCHWith the P after renewal
E-base, the transmitting power P of calculating HS-SICH

Embodiment two:
In up associating circule power control method, the second implementation is: a plurality of up channels with carrier wave are shared P
E-base, each channel is safeguarded closed-loop power control GAP separately, carries out up associating power control.Wherein HS-SICH when the closed-loop power control GAP of self is not overtime, adopts existing mode to carry out closed-loop power control; HS-SICH adopts with the similar mode of E-PUCH and carries out closed-loop power control after the closed-loop power control GAP of self is overtime, namely utilizes the TPC instruction to upgrade the P that shares
E-base, and the P to share
E-baseFor determining transmitting power in the basis.
In the present embodiment, to carrying out up associating power control with carrier wave E-PUCH and HS-SICH, concrete circule power control method flow process comprises as shown in Figure 2:
Step 201 sets in advance E-PUCH corresponding to the multiple transmission code rate of E-DCH and the power adjustment of HS-SICH.
The realization of this step is identical with step 101, just repeats no more here.
Here, E-PUCH and HS-SICH can adopt the definite closed-loop power control GAP separately of existing mode.
Step 203 is according to the closed-loop power control GAP of E-PUCH and HS-SICH, shared P
E-base, E-PUCH is carried out power controls.
Wherein, when determining the transmitting power of E-PUCH, at first determine the TPC order corresponding to this E-PUCH, determine that specifically mode is with existing identical.
Then, judge whether the closed-loop power control GAP of E-PUCH is overtime, judgment mode is with existing identical; If not overtime, upgrade according to the TPC order of determining the current P that shares
E-base, then according to the P after upgrading
E-baseCalculate transmitting power according to existing mode.
If the closed-loop power control GAP of E-PUCH is overtime, judge further whether the closed-loop power control GAP of HS-SICH is overtime, if not overtime, will upgrade for the last time P
E-baseAll TPC orders that receive and up-to-date P afterwards
E-baseAdd up, determine the P of current shared
E-base, and according to the P that determines
E-baseCalculate the uplink transmission power of E-PUCH according to existing mode.
If the closed-loop power control GAP of the closed-loop power control GAP of E-PUCH and HS-SICH is all overtime, determine the transmitting power of E-PUCH by open loop according to existing mode.
Under the power control mode of above-mentioned E-PUCH, after the closed-loop power control GAP of E-PUCH is overtime, as long as the closed-loop power control GAP of HS-SICH is not overtime, still can determine P according to the transmitting power of HS-SICH
E-baseThereby, proceed the closed-loop power control of E-PUCH, therefore, with embodiment one similarly, the E-PUCH power control mode in the present embodiment has greatly increased and has carried out the probability of closed-loop power control, thereby has reduced due to open loop power control the strong jamming of other channels.
Step 204 is for HS-SICH, according to the closed-loop power control GAP of HS-SICH and E-PUCH, shared P

HS-SICHWith the P after renewal
E-base, the transmitting power P of calculating HS-SICH
HS-SICH=P
E-base+ L+ β
HS-SICH, wherein, L is circuit loss value.Compare as seen with the power control in embodiment one, in the situation that HS-SICH closed-loop power control GAP is overtime and E-PUCH closed-loop power control GAP is not overtime, HS-SICH adopts the closed-loop power control mode identical with HS-SICH in embodiment one.
If the closed-loop power control GAP of the closed-loop power control GAP of HS-SICH and E-PUCH is all overtime, according to existing mode, HS-SICH is carried out open loop power control.
Under the power control mode of above-mentioned HS-SICH, on the one hand when the closed-loop power control GAP of HS-SICH is not overtime, adopt the mode of having now to carry out closed-loop power control, thus compatible existing HS-SICH power control mode to greatest extent; On the other hand, after HS-SICH closed-loop power control GAP is overtime, as long as the closed-loop power control GAP of E-PUCH is not overtime, still can be according to the P that shares
E-base, proceed the closed-loop power control of HS-SICH, with embodiment one similarly, the E-PUCH power control mode in the present embodiment has greatly increased and has carried out the probability of closed-loop power control, thereby has reduced due to open loop power control the strong jamming of other channels; And with similar ground in embodiment one, the closed-loop power control that carries out after HS-SICH closed-loop power control GAP is overtime can be complementary with the expectation received power of HS-SICH, realizes good power control performance.
As seen by above-mentioned, in the present embodiment, HS-SICH carries out different closed-loop power controls stage by stage, because HS-SICH is not that explicitly is safeguarded and renewal P always
E-base, but may directly regulate self transmitting power, so E-PUCH if the closed-loop power control GAP of this E-PUCH is overtime, in the time of need to utilizing HS-SICH to carry out closed-loop power control, at first needs to upgrade current P when determining transmitting power
E-baseConcrete update mode is about to rear all the TPC orders that receive of last renewal and is added to up-to-date P as previously mentioned
E-baseOn, like this, the P after renewal
E-baseAlso just be equivalent to upgrade therefore according to each TPC order, can obtain P accurately
E-baseBe worth, then can carry out the closed-loop power control of E-PUCH.
For the step 203 in embodiment two and 204, be only for convenience of describing, introducing sequentially; In fact, for the power control of E-PUCH and HS-SICH, be to carry out according to the signal transmission order of reality, namely the execution sequence with existing mode is identical.
In addition, with the similar ground of embodiment one, be positioned at different time slots if participate in the different channels of associating power control, at shared P
E-baseThe time, need to make an uproar to differ from according to the end of different time-gap and adjust.
Above-mentioned two kinds of implementations that are up associating power control in the present invention.Next descending associating power control is described.
Embodiment three:
In descending associating power control, share P with a plurality of down channels of carrier wave
E-base, each channel is safeguarded respectively closed-loop power control GAP separately, carries out descending associating power control.The down channel that wherein carries out the associating power control comprises E-HICH secondary spreading code, thereby realizes the power of this E-HICH secondary spreading code is controlled.
In the present embodiment, to carrying out descending associating power control with carrier wave E-HICH secondary spreading code, HS-SCCH and E-AGCH.In the following description, as without special suggestion, E-HICH secondary spreading code, HS-SCCH and E-AGCH all refer to the respective channel with carrier wave.Concrete circule power control method flow process comprises as shown in Figure 3:
The purpose of this step process is identical with the purpose of first step in the first two embodiment.For realizing the associating power control of three channels, need to determine their mutual difference powers, like this for arbitrary channel, can according to the transmitting power of other channels, calculate the transmitting power of this arbitrary channel.
wherein, HS-SCCH has two kinds of transformats, E-AGCH also has two kinds of transformats, under different transpost formats, corresponding expectation received power is difference to some extent, therefore carrying out difference power when arranging, need to be for different transformats, corresponding difference power is set, difference power between E-HICH secondary spreading code and the first HS-SCCH form namely is set, difference power between E-HICH secondary spreading code and the second HS-SCCH form is set, difference power between E-HICH secondary spreading code and the first E-AGCH form is set, difference power between E-HICH secondary spreading code and the second E-AGCH form is set.
The concrete mode of determining set difference power and arranges β in embodiment one
λ 1Similar, difference power between E-HICH secondary spreading code and the first HS-SCCH form to be set as example, in advance emulation is carried out in HS-SCCH transmission and the transmission of E-HICH secondary spreading code of the first form, be defined as reaching the receptivity of system requirements, the expectation received power between the first HS-SCCH form and E-HICH secondary spreading code is poor.
Step 302, the power that E-HICH secondary spreading code is set is adjusted thresholding and closed-loop power control GAP, and the power that HS-SCCH is set is adjusted thresholding and closed-loop power control GAP, and the power that E-AGCH is set is adjusted thresholding and closed-loop power control GAP.
Wherein, the power of HS-SCCH and E-AGCH is adjusted thresholding and closed-loop power control GAP, adopts with existing identical mode to arrange.And for E-HICH secondary spreading code, according to characteristic and the system requirements of this channel, arrange according to the mode identical with HS-SCCH.
In this step, UE adjusts thresholding according to the power of the E-HICH secondary spreading code that arranges, and determines the TPC order corresponding to this E-HICH secondary spreading code.Concrete mode is identical with HS-SCCH, just repeats no more here.This shows, in the present embodiment, the TPC order of E-HICH secondary spreading code is filled in no longer at random, but produces according to the transmission performance of E-HICH secondary spreading code, thus for the power control of carrying out E-HICH secondary spreading code ready.
The mode of UE feedback TPC order is with existing identical, namely by semi-continuous E-PUCH feedback.After NodeB receives this TPC order, different from existing processing mode of not resolving, in the present embodiment, after NodeB receives the TPC order of feedback, whether the closed-loop power control GAP that judges this E-HICH secondary spreading code is overtime, and concrete judgment mode is identical with the judgment mode of HS-SCCH.
If not overtime, according to the TPC order of feedback, the transmitting power of E-HICH secondary spreading code is adjusted.
If the closed-loop power control GAP of E-HICH secondary spreading code is overtime, whether the closed-loop power control GAP that further judges HS-SCCH and E-AGCH is overtime, if wherein the closed-loop power control GAP of arbitrary channel is not overtime, never select a channel of up-to-date transmission in overtime channel, according to the latest emission power of this channel of selecting and the difference power between this channel and E-HICH secondary spreading code, determine the transmitting power of E-HICH secondary spreading code, the latest emission power of the channel that is about to select and difference power sum are as the transmitting power of E-HICH secondary spreading code.Wherein, then the transformat that needs definite channel that this is selected to adopt utilizes the difference power between respective transmissions form and E-HICH secondary spreading code, calculates the transmitting power of E-HICH secondary spreading code.
If the closed-loop power control GAP of closed-loop power control GAP, the HS-SCCH of E-HICH secondary spreading code and the closed-loop power control GAP of E-AGCH are all overtime, E-HICH is carried out open loop power control.Can the employing mode identical with HS-SCCH or E-AGCH, determine the open loop power of E-HICH secondary spreading code.

Step 304 for HS-SCCH or E-AGCH, is carried out the associating power control according to the closed-loop power control GAP of closed-loop power control GAP, the HS-SCCH of E-HICH secondary spreading code and the closed-loop power control GAP of E-AGCH.
For HS-SCCH and E-AGCH, its power control process is basic identical, describes as an example of HS-SCCH example here.
At first, UE adjusts thresholding according to the power of the HS-SCCH that arranges, determines the TPC order corresponding to this HS-SCCH, and feeds back to NodeB; Specific implementation is with existing identical.
Then, NodeB receives the TPC order of feedback, judges whether the closed-loop power control GAP of HS-SCCH is overtime, if not overtime, according to existing mode, determines the transmitting power of HS-SCCH according to the TPC order of feedback.
If the closed-loop power control GAP of HS-SCCH is overtime, if the closed-loop power control GAP of E-AGCH is not overtime, can determine according to the transmitting power of E-AGCH the transmitting power of HS-SCCH, implementation is with existing identical; Perhaps, if the closed-loop power control GAP of E-HICH secondary spreading code is not overtime, can be according to the latest emission power of E-HICH secondary spreading code, and the difference power between E-HICH secondary spreading code and this HS-SCCH corresponding format, calculate the transmitting power of HS-SCCH, be about to E-HICH secondary spreading code and this difference power sum, as the transmitting power of HS-SCCH.
If the closed-loop power control GAP of the closed-loop power control GAP of closed-loop power control GAP, the E-AGCH of HS-SCCH and E-HICH secondary spreading code is all overtime, determine the transmitting power of HS-SCCH according to open loop approach.
For E-AGCH, in the situation that its closed-loop power control GAP is overtime, if the closed-loop power control GAP of E-AGCH is not overtime, can determine according to the transmitting power of E-AGCH the transmitting power of HS-SCCH, implementation is with existing identical; Perhaps, if the closed-loop power control GAP of E-HICH secondary spreading code is not overtime, can be according to the latest emission power of E-HICH secondary spreading code, and the difference power between E-HICH secondary spreading code and this E-AGCH corresponding format, calculate the transmitting power of E-AGCH, be about to E-HICH secondary spreading code and this difference power sum, as the transmitting power of E-AGCH.
With the similar ground of the power control of above-mentioned E-HICH secondary spreading code, the power control process of HS-SCCH and E-AGCH in the present embodiment, with respect to the power control process of existing HS-SCCH and E-AGCH, the probability of closed-loop power control increases greatly, has reduced due to open loop power control the strong jamming of other channels.
