Description

Wireless cellular network Poewr control method
Technical field
The present invention relates to mobile communication technology field, more particularly to a kind of wireless cellular network Poewr control method.
Background technology
The service that wireless cellular network is provided for each user needs to meet certain service quality (QoS), QoS mainly by The signal interference ratio (SIR) that each user receives signal determines.Therefore, distribution of the wireless cellular network to radio resource, particularly It is just more important to the power distribution of each user link.For WCDMA system, although same community user relies on orthogonal expansion Frequency code is mutually isolated, but due to the use of identical frequency range and time slot, and the multipath of wireless channel, delay are believed between still resulting in user It number interferes with each other.Power control techniques can effectively solve the problems, such as this, can ensure physical channel transmission quality requirements Under the premise of, base station or the transmission power of user are limited as much as possible, so as to reduce the interference that other are used with signal as far as possible, are carried High power system capacity, while the stand-by time of extending cell phone.
From the angle of uplink and downlink, uplink power control and downlink power control are divided in WCDMA, uplink power control refers mainly to The transmission power of mobile station UE is controlled, downlink power control refers mainly to control the transmission power of base station particular channel System.Fig. 1 is downlink power control schematic diagram, as shown in Figure 1, downlink power control includes open sea wharf and inner loop power control System.In order to ensure that downlink signal that terminal receives meets Block Error Rate (BLER) requirement of network side, open sea wharf generation For the sir target value of inner-loop power control, sir target value is according to cyclic redundancy check (CRC) result tune of downlink data block Whole, CRC correctly then lower by sir target value, and then sir target value raises crc error.Inner-loop power control is by comparing downlink reception The SIR estimation value of signal and the sir target value of open sea wharf generation, the TPC command of generation adjustment base station power.Work as SIR When estimated value is less than or equal to sir target value, TPC sends UP command " 1 ";Otherwise TPC sends down command " 0 ".
When terminal is in deep fade environment, base station cannot still make terminal received signals matter with maximum transmission power transmitting Amount reaches desired value.If without protection mechanism, the open sea wharf of terminal will constantly increase sir target value, this existing As for deep fading (Wind up) state.In this case, sir target value may increase to maximum value, work as link-quality When restoring normal, since sir target value lowers step-length much smaller than up-regulation step-length, terminal needs to take a long time just can be with Sir target value is reduced to normal value.During this period of time, base station transmitting power is higher than practically necessary value, so as to it His user causes larger interference.Therefore, it is necessary to carry out special setting to the sir target value after entrance deep fade state, no It can directly be adjusted according to downlink CRC results.
As shown in Fig. 2, existing deep fading's detection technique is according to downlink reception data BLER statistical values and feeds back to base station TPC command up-regulation ratio detection deep fade state, there are problems that deep fade state's flase drop.Under actual conditions, When channel circumstance is deteriorated suddenly, BLER can also become larger suddenly, and the ratio of TPC up-regulations can also rise, and terminal may enter Deep fade state, but base station power does not reach maximum value at this time, and erroneous judgement will cause to use into before deep fade state Meet the sir target value of BLER requirements as SIRwindup, less than the sir target value needed after channel circumstance variation, base station power It can not be lifted, user's downlink signal quality cannot improve always, and being chronically at deep fade state can not jump out, final link It disconnects, seriously affects terminal capabilities.
Further, the desired value SIR used during deep fade statewindupIt chooses unreasonable.According to current calculation Method, into before deep fade state, if 0.7BLERtarget≤BLER≤1.3BLERtarget, then update and record at this time The average value of sir target value is as SIRwindup, it can be seen that SIRwindupWhat is selected is historical experience value, but is entered in fact deep Downlink context has been deteriorated when spending fading condition, and once rational value was relatively low herein.
Therefore, it is necessary to design a kind of channel circumstance variation or deep fade environment suddenly, when terminal enters deep fade state, Quick selection is suitble to the sir target value of present channel environment, and terminal is helped quickly to jump out the wireless cellular network of deep fade state Network Poewr control method, with solve the problem of presently, there are enter deep fade state after can not jump out link is caused to disconnect.

<Example IV>
Fig. 5 is specific embodiment of the invention wireless cellular network Poewr control method flow chart, as shown in figure 5, this implementation The technical solution of example is as follows:
Step 1:Deep fade state's sign of flagwindup0 is set as, i.e., is currently non-deep fade state.
Step 2:Sir target value is adjusted according to CRC results, if CRC is correct, sir target value reduces Δdw, otherwise, Sir target value increases Δup(initial value SIRinit)。
Step 3:TPC statistic windows are updated, are several TPC control words (the alternately filling up-regulations for the first time generated recently in window And down command), and the number N that TPC command raises in statistic windowup;The CRC check in BLER statistic windows is updated as a result, and counting Calculate BLER.
Open sea wharf mainly generates the sir target value needed for inner-loop power control, according to CRC check result tune Whole, correctly then sir target value lowers Δ to CRCdw, then sir target value raises Δ to crc errorup.Meanwhile often obtain a CRC school It tests as a result, count several nearest check results, exports BLER statistical values.Inner-loop power control is by comparing SIR estimation value With sir target value, the TPC command of generation adjustment base station power.When SIR estimation value is less than or equal to sir target value, TPC is sent UP command " 1 ";Otherwise TPC sends down command " 0 ".A TPC control word is often generated, counts nearest WTPCA TPC as a result, Export TPC up-regulation times NsupWith downward times Ndw
Step 4:If 0.7BLERtarget≤BLER≤1.3BLERtarget, then several nearest sir target values are calculated Average value SIRavg(initial value SIR is filled for the first timeinit);Otherwise directly it is transferred to step 5.
Step 5:If BLER is more than or equal to thresholding InThBLERAnd NupMore than or equal to thresholding InThTPC, then state be transferred to Deep fade state enters step 6;Otherwise return to step 1.Benefit of the detection of deep fade state as downlink power control It fills, lowering ratio according to the up-regulation of BLER and the downlink TPC command returned is detected and jumps out, and specific rule is as follows: BLER values are more than or equal to decision threshold InThBLERAnd TPC raises times NupMore than or equal to thresholding InThTPCWhen, it declines into depth Fall state;The number C that BLER is continuously reduceddwMore than or equal to decision threshold OutThBLERAnd TPC lowers times NdwIt is more than or equal to Thresholding OutThTPCWhen, jump out deep fade state.When terminal is in deep fade state, sir target value is according into depth Average value SIR before fading conditionavgIt calculates, is not adjusted further according to CRC results, until going out deep fade state.
Step 6:Deep fade state's timer TwindupIt resets, the initial sir target value below two of deep fade state A kind of setting is taken in kind method:(1) it is set as SIRwindup=SIRagvcomp, wherein ΔcompFor constant offset, empirical value is taken 3dB;(2) it is set as SIRwindup=(SIRagv+SIRtgt)/2, wherein SIRtgtA nearest SIR before into deep fade state Desired value.
Step 7:Deep fade state's sign of flagwindup1 is set as, i.e., is currently deep fade state.
Step 8:Timer TwindupIncrease 1.
Step 9:If TwindupReach maximum of Tmax, then SIRwindupIncrease Delta, TwindupReset, otherwise directly into Enter step 10.
Step 10:Update TPC statistic windows, and the number N that TPC command is lowered in statistic windowdw;It updates in BLER statistic windows CRC check is as a result, and calculate the number C that BLER is continuously reduceddw
Step 11:If CdwMore than or equal to thresholding OutThBLERAnd NdwMore than or equal to thresholding OutThTPC, then state be transferred to Non- deep fade state, return to step 1;Otherwise deep fade state, return to step 7 are kept.
It is quickly exited in algorithm into deep fade state in mistake provided by the invention, enters deep fading by proposing two kinds The choosing method of sir target value after state, in history average SIRavgOn the basis of be superimposed a compensation rate ΔcompOr take into Enter nearest SIR before deep fade statetgtWith history average SIRavgAverage value, increase to entering deep fade state The considerations of influence that down channel environment can be deteriorated afterwards, to the sir target value SIR used during deep fade statewindupIt chooses More rationally, and Adaptive adjusting algorithm is employed, makes SIRwindupIt is adjusted to meet BLER as early as possibletargetDemand, so as to carry High downlink signal quality helps terminal to jump out deep fade state as early as possible.
Further, the present invention is by increasing deep fade state's timer TwindupIf in time TmaxAfterwards, can't Meet deep fading's exit criteria, then by SIRwindupIncrease Delta;If TmaxMeet deep fading in time and exit item Part then directly exits deep fade state.It is deteriorated suddenly in channel circumstance but not deep fade environment, terminal is missed into deep fading It is quick to calculate the sir target value for being suitble to present channel environment during state, terminal is helped quickly to jump out deep fade state.It solves Current scheme is existing accidentally into the problem of can not jumping out, link is caused to disconnect after deep fade state.
