Description
Technical field
The present invention relates to the power control techniques in the communication system, particularly a kind of high-speed packet inserts up associating power control and the descending associating circule power control method in (HSPA).
Background technology
In the TD-SCDMA system, by introducing the throughput that HSUPA and HSDPA technology can improve the uplink and downlink data.
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, the parallel uplink power control of safeguarding separately of multiple mode.
Particularly, uplink power control process for E-PUCH is: network disposes expectation received power by Radio Resource control (RRC) module 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 is provided with transmitting power; If the GAP counting is overtime, UE is that benchmark is provided with transmitting power with the expectation received power (open loop Pebase) of RRC configuration.
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 of reception, determines to raise or reduce the E-PUCH transmitting power, thereby determines and issue TPC by E-AGCH or E-HICH to UE to order; UE orders P according to the TPC that receives
E-baseAdjust, after " up " order of receiving TPC, P
E-baseOn the basis of original numerical value, increase Δ e-base, after " down " order of receiving TPC, P
E-baseOn the basis of original numerical value, reduce Δ e-base.The size of Δ e-base value is disposed 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 a 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 is provided with transmitting power with the closed power of current maintenance; If the GAP counting is overtime, UE is that benchmark is provided with transmitting power with the HS-SICH expectation received power of RRC configuration.
Uplink power control process for E-RUCCH is: NodeB is reference with the open loop power of SYNC UL, and the power mandate of E-RUCCH is set, and sends to UE by FPACH.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 a transmission code rate to DPCH and carries out closed-loop power control, in this closed-loop power control process, only based on the target SIR of this DPCH, determine the TPC order, carry out the power adjustment, and do not consider the interference and the influence that cause for other channels making an uproar at the bottom of the equipment and causing.
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 bigger usually, thereby cause other up channels with carrier wave are formed bigger uplink interference, especially when HS-SICH and the synchronic crack of E-PUCH, the up open loop power of arbitrary channel all can cause the strong jamming to the other side's channel in the two.
In TD-SCDMA agreement and high-speed packet evolution (HSPA+) agreement, down channel HS-SCCH and E-AGCH carry out independently descending 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 provided with transmitting power according to the closed power of current maintenance according to the TPC order; If the GAP counting is overtime, NodeB is that benchmark is provided with transmitting power with the HS-SCCH expectation received power of network configuration.Wherein, UE determines and the mode of feedback TPC order is: UE compares according to the HS-SCCH of reception and default power control thresholding, if greater than this thresholding, and the then TPC order of generation reduction power, if less than this thresholding, the TPC that then generates raising power orders.
For the uplink power control process of E-AGCH and the uplink power control similar process of above-mentioned HS-SCCH, just the open loop power of the E-AGCH that is provided with and GAP value can be different.Here just repeat no more.Above-mentioned two channels carry out descending power control independently of one another.
The E-HICH channel is used to carry 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 descending power control to E-HICH secondary spreading code.That is to say that 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 sends the intensity of signal owing to can't know NodeB, therefore, can't determine the current downlink channel quality.

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, E-PUCH is carried out power control according to existing mode.
Wherein, when determining the transmitting power of E-PUCH, at first determine TPC order, determine that specifically mode is with existing identical corresponding to this E-PUCH; Then, judge whether unified closed-loop power control GAP is overtime, judgment mode is with existing identical; If not overtime, then upgrade the current P that shares according to the TPC order of determining
E-base, again according to the P after upgrading
E-baseCalculate transmitting power according to existing mode; If overtime, then determine transmitting power by open loop according to existing mode.
In above-mentioned power control process to E-PUCH, the P that E-PUCH upgrades
E-baseAfter may upgrading 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,,, have HS-SICH and DPCH to safeguard P as long as in closed-loop power control GAP even therefore last time, the E-PUCH transmission exceeded closed-loop power control GAP with the time interval that this E-PUCH transmits
E-base, E-PUCH still can carry out closed-loop power control.Therefore, increased greatly and carried out the probability of closed-loop power control, thereby reduced because open loop power control and to 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 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 is provided with in the step 101
λ 1Determine the power adjustment β of this HS-SICH with respect to E-DCH benchmark code check
HS-SICH, again according to β

Wherein, may take many code channels owing to distribute to the HS-SICH of UE, and the β that is provided with in the 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 be according to the β that is provided with
λ 1With the actual code channel number that takies of the HS-SICH that distributes to UE, determine the power adjustment β of the HS-SICH of this distribution with respect to E-DCH benchmark code check

The realization of this step is identical with step 101, just repeats no more here.
Step 202, corresponding E-PUCH and HS-SICH are provided with closed-loop power control GAP separately respectively.
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 control.
Wherein, when determining the transmitting power of E-PUCH, at first determine TPC order, determine that specifically mode is with existing identical corresponding to this E-PUCH.
Then, judge whether the closed-loop power control GAP of E-PUCH is overtime, judgment mode is with existing identical; If not overtime, then upgrade the current P that shares according to the TPC order of determining
E-base, again 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 then whether the closed-loop power control GAP of HS-SICH is overtime, if not overtime, then will upgrade P for the last time
E-baseAll TPC that receives orders 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, then 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,, still can determine P according to the transmitting power of HS-SICH as long as the closed-loop power control GAP of HS-SICH is not overtime
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 increased greatly and has carried out the probability of closed-loop power control, thereby has reduced because open loop power control and to the strong jamming of other channels.

HS-SICHWith the P after the renewal
E-base, the transmitting power P of calculating HS-SICH
HS-SICH=P
E-base+ L+ β
HS-SICH, wherein, L is a circuit loss value.Compare as seen with the power control among the embodiment one, under and the situation that E-PUCH closed-loop power control GAP is not overtime overtime at HS-SICH closed-loop power control GAP, HS-SICH adopts the closed-loop power control mode identical with HS-SICH among the 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, then HS-SICH is carried out open loop power control according to existing mode.
Under the power control mode of above-mentioned HS-SICH, when the closed-loop power control GAP of HS-SICH is not overtime, adopt existing mode to carry out closed-loop power control on the one hand, thus compatible to greatest extent existing HS-SICH power control mode; 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 increased greatly and has carried out the probability of closed-loop power control, thereby has reduced because open loop power control and to the strong jamming of other channels; And with similar ground among the 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 utilizing HS-SICH to carry out closed-loop power control, at first needs to upgrade current P when determining transmitting power
E-baseSpecifically update mode is about to last all TPC orders of upgrading the back reception and is added to up-to-date P as previously mentioned
E-baseOn, like this, the P after the renewal
E-baseAlso just be equivalent to upgrade therefore, can obtain P accurately according to each TPC order
E-baseBe worth, can carry out the closed-loop power control of E-PUCH then.
For the step 203 among the embodiment two and 204, only be to describe for convenient, introduce 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, promptly the execution sequence with existing mode is identical.
In addition, with embodiment one similar ground, be positioned at different time slots if participate in the different channels of associating power control, then at shared P
E-baseThe time, need 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 among 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 closed-loop power control GAP separately respectively, carries out descending associating power control.Wherein carry out comprising E-HICH secondary spreading code in the down channel of associating power control, thereby realize power control this E-HICH secondary spreading code.
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 no 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:
Step 301 sets in advance E-HICH secondary spreading code respectively and the difference power between two kinds of forms of HS-SCCH, and E-HICH secondary spreading code respectively and the difference power between two kinds of forms of E-AGCH.
The purpose of this step process is identical with the purpose of first step among preceding two embodiment.For realizing the associating power control of three channels, need to determine their mutual difference powers, like this for arbitrary channel, can calculate this arbitrary channel transmitting power according to other channel transmitting power.
Wherein, HS-SCCH has two kinds of transformats, E-AGCH also has two kinds of transformats, under the different transpost formats, corresponding expectation received power is difference to some extent, therefore carrying out difference power when being provided with, need be at different transformats, corresponding difference power is set, the difference power between E-HICH secondary spreading code and first kind of HS-SCCH form promptly is set, difference power between E-HICH secondary spreading code and second kind of HS-SCCH form is set, difference power between E-HICH secondary spreading code and first kind of E-AGCH form is set, difference power between E-HICH secondary spreading code and second kind of E-AGCH form is set.
The concrete mode of determining set difference power and is provided with β among the embodiment one
λ 1Similar, with the difference power that is provided with between E-HICH secondary spreading code and first kind of HS-SCCH form is example, HS-SCCH to first kind of form transmits and E-HICH secondary spreading code transmission carrying out emulation in advance, be defined as reaching the receptivity of system requirements, the expectation received power between first kind of HS-SCCH form and the E-HICH secondary spreading code is poor.
Wherein, the power of HS-SCCH and E-AGCH is adjusted thresholding and closed-loop power control GAP, adopts with existing identical mode to be provided with.And for E-HICH secondary spreading code, then according to the characteristic and the system requirements of this channel, be provided with 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 is provided with, 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 that the TPC of E-HICH secondary spreading code order is filled in no longer at random in the present embodiment, but produces according to the transmission performance of E-HICH secondary spreading code, thereby be that the power control of carrying out E-HICH secondary spreading code is got ready.
The mode of UE feedback TPC order is with existing identical, promptly by semi-continuous E-PUCH feedback.After NodeB receives this TPC order, different with 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, then the transmitting power of E-HICH secondary spreading code is adjusted according to the TPC order of feedback.
If the closed-loop power control GAP of E-HICH secondary spreading code is overtime, whether the closed-loop power control GAP that then further judges HS-SCCH and E-AGCH is overtime, if wherein the closed-loop power control GAP of arbitrary channel is not overtime, select a channel of up-to-date transmission in the then never 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, need to determine the transformat of this channel of selecting employing, utilize the difference power between respective transmissions form and E-HICH secondary spreading code then, calculate 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, then 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.
By as seen above-mentioned, in the present embodiment, realized power control for E-HICH secondary spreading code, therefore, UE can carry out downlink quality according to E-HICH secondary spreading code and detect; And in the control of the power of this E-HICH secondary spreading code, for existing HS-SCCH or E-AGCH, the probability of its closed-loop power control increases greatly, thereby has reduced owing to open loop power control and to the strong jamming of other channels.
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, is that example describes here with HS-SCCH.
At first, UE adjusts thresholding according to the power of the HS-SCCH that is provided with, 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, then 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, then, can determine the transmitting power of HS-SCCH according to the transmitting power of E-AGCH if the closed-loop power control GAP of E-AGCH is not overtime, 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 closed-loop power control GAP, the E-AGCH of HS-SCCH and the closed-loop power control GAP of E-HICH secondary spreading code are all overtime, then determine the transmitting power of HS-SCCH according to open loop approach.
For E-AGCH, under the overtime situation of its closed-loop power control GAP,, can determine the transmitting power of HS-SCCH according to the transmitting power of E-AGCH if the closed-loop power control GAP of E-AGCH is not overtime, 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 because open loop power control and to the strong jamming of other channels.
In the foregoing description,, only be to describe, introduce sequentially for convenient for step 303 and 304; In fact, for the power control of E-HICH secondary spreading code, HS-SCCH and E-AGCH, be to carry out according to the signal transmission order of reality, promptly the execution sequence with existing mode is identical.
In addition, with embodiment one similar ground, be positioned at different time slots if participate in the different channels of associating power control, then at shared P
E-baseThe time, need make an uproar to differ from according to the end of different time-gap and adjust.
