One embodiment of the invention provides a kind of control method of transmitting power, and is as shown in Figure 1, and this method can comprise:
101. the measurement report according to the pairing channel of target control side obtains this measurement report corresponding coding manner;
The target control side here just will be carried out the target of transmitting power control, for time-division system, and gsm system for example, the target control side can (Base TransceiverStation BTS), also can be the terminal for base transceiver station.
When the target control side is BTS; Base station controller BSC (Base Station Controller) gets access to is the measurement report that down channel is measured that is sent by the terminal, and this measurement report can be the timeslot-level measurement report of the channel quality carved at a time of the downlink traffic channel of using that the terminal is measured; It also can be the comprehensive channel quality that obtains is measured at the terminal to a plurality of downlink traffic channel user class measurement report; Can be other forms of measurement report also, not give an example one by one here.
When the target control side is the terminal; Base station controller gets access to here is the measurement report that reverse link traffic channel is measured that is sent by BTS, and this measurement report can be the timeslot-level measurement report of the channel quality carved at a time of the reverse link traffic channel that is using that BTS measures; It also can be BTS measures the comprehensive channel quality that obtains to a plurality of reverse link traffic channels user class measurement report.Can be other forms of measurement report also, not give an example one by one here.
Generally speaking; Can comprise error rate parameter in the measurement report; Like MEAN_BEP (themean bit error probability calculated over all received bits in the block; The average bit error bit rate of radio block) parameter and CV_BEP (the coefficient of variation of the biterror probability of the block, the error code bit rate coefficient of variation of radio block) parameter.And obtain the measurement report corresponding coding manner promptly is according to the error rate parameter in the measurement report; Calculate error rate parameter corresponding coding manner; Concrete computational methods those skilled in the art can pass through LA of the prior art (Link Adaptation, link circuit self-adapting) algorithm and realize.Such as in the Packet Service of gsm system, being 31 according to the error rate parameter MEAN_BEP grade in the measurement report, the CV_BEP grade is 7, obtains the respective coding mode through the LA algorithm and is MCS9.
102. according to controlling said channel transmitting power with the pairing carrier/interface ratio of said coded system with the corresponding carrier/interface ratio of said measurement report.
There is certain corresponding relation between coded system and the carrier/interface ratio,, can obtains and the pairing carrier/interface ratio of this coded system by coded system according to this corresponding relation.Generally speaking; Coded system can corresponding several carrier/interface ratios; And because under the identical coded system, message transmission rate is identical, and the high more power consumption of carrier/interface ratio is also just high more; Under the situation that reaches identical traffic speed, therefore can be with the target carrier/interface ratio of wherein minimum carrier/interface ratio as power control.Can obtain through the error rate parameter maps in the measurement report and obtain the corresponding carrier/interface ratio of measurement report; Can the error rate parameter maps in the measurement report be become corresponding carrier/interface ratio through the backstepping method according to the corresponding relation of carrier/interface ratio, error rate parameter and measurement report such as those skilled in the art.The difference of the carrier/interface ratio that the minimum carrier/interface ratio in the carrier/interface ratio of acquisition coded system correspondence is corresponding with measurement report can obtain power contorl parameters; This power contorl parameters is sent out to the target control side, and the target control side can be carried out the adjustment of transmitting power according to the power contorl parameters that receives.And this power contorl parameters can be represented with the form of step-length, and the size of step-length can be provided with by system in advance.The target control lateral root is adjusted according to the emission control of power control step-size, i.e. the may command transmitting power.
In order to make power control more accurately with stable, power control is preferably in when the destination channel transmission environment is comparatively stablized and carries out in this enforcement, and wherein destination channel is meant the channel that need carry out power control.The error rate of the transmission rate of channel and destination channel is just more stable when the destination channel transmission environment is comparatively stablized; Can significantly not change; Adjust the transmitting power of target control side this moment, and the variation of the variation of power and destination channel transmission environment can become more stable and accurate.And judge whether stable manner can have multiple the Channel Transmission environment: for example can be according to the measurement report of receiving before step 102; Whether the number of times that statistics gets access to the same-code mode continuously reaches preset targeted number; If reach preset targeted number; Then explanation channel circumstance at this moment is more stable, otherwise, explain that the channel circumstance of this moment is unstable; Whether the signal received power that can also before step 101 or 102, judge the target control side is in stable power interval range; If the signal received power of target control side is in stable power interval range; Then the transmission environment of said channel is a stable state; Otherwise, explain that the channel circumstance of this moment is unstable.Wherein, the stable power interval range of signal power can-6db～+ 6db between, can certainly be other scope.
Wherein the statistics to the measurement report corresponding coding manner can be a continuation; That is to say; The measurement report corresponding coding manner is added up always, reach targeted number, then can starting power control if receive the number of times of same-code mode continuously; Statistics to the measurement report corresponding coding manner also can be an Event triggered; If (be appreciated that and be statistics startup thresholding) when receiving the measurement report corresponding coding manner greater than a certain numerical value; Then start statistics to the measurement report corresponding coding manner; If in statistic processes, variation has taken place in the measurement report corresponding coding manner, then need continue to wait until to begin when receiving the measurement report corresponding coding manner greater than a certain numerical value to add up again again; Reach targeted number if receive the number of times of same-code mode continuously, then can starting power control; In addition; Statistics to the measurement report corresponding coding manner can also be periodic; That is to say the statistics that periodically starts the measurement report corresponding coding manner; Any time value is added up as one-period in for example can 300～500ms, if the number of times that receives the same-code mode continuously according to statistics reaches targeted number, and then can starting power control.
The embodiment of the invention is through the measurement report of target control side carrier frequency power control institute respective channels; Can know the coded system of target control side respective channels; Carrier/interface ratio and the corresponding carrier/interface ratio of measurement report through this coded system is corresponding are accurately controlled the transmitting power of target control side institute control channel; This power control mode both can carry out power control to timeslot-level measurement report; Promptly more accurately control the transmitting power of individual channel, thereby accurately adjust the signal quality in this individual channel, promote single-channel communication resource distribution and service quality; Also can carry out power control, promptly through more accurately controlling the signal quality of the integral body in the next accurately adjustment of a plurality of channel transmitting power channel group to the measurement report of user class.
In order to make those skilled in the art make much of the control method of the described channel emission power of the embodiment of the invention more, respectively the control method of down channel and uplink channel transmission power is elaborated below.
Another embodiment of the present invention provides a kind of control method of transmitting power, is that BTS is the example explanation with the target control side wherein, and as shown in Figure 2, the transmit power controlling method in the present embodiment comprises:
201. the measurement report that receiving terminal sends.
For example, the terminal can according to request or periodically or Event triggered send measurement report to down channel, as previously mentioned, this measurement report can be timeslot-level also can be user class or the like.Wherein, each timeslot-level down-run survey report can be sent according to the grouping downlink acknowledge message in the agreement in the terminal.
202. obtain each measurement report corresponding coding manner.
In this step; According to the measurement report that receives, can get access to measurement parameter wherein through filtering, such as error rate parameter (like MEAN_BEP and CV_BEP etc.); Obtain each error rate corresponding coding manner according to the LA algorithm again, thereby obtain the measurement report corresponding coding manner.Such as in the Packet Service of gsm system, being 31 according to the error rate parameter MEAN_BEP grade in the measurement report, the CV_BEP grade is 7, and then obtaining the respective coding mode through the LA algorithm is MCS9.
203. the magnitude relationship of the coded system thresholding of coded system that judgement gets access to and starting power control;
If the coded system that gets access to is not less than the coded system thresholding of starting power control, then change step 204 over to; Otherwise continue execution in step 201-202.
Generally speaking, have the corresponding higher carrier/interface ratio interval of coded system of high value, thus corresponding preferable Channel Transmission environment.If the coded system value is lower, the interval boundary of carrier/interface ratio is not obvious, and power control effect is not good.And pass through the coded system thresholding that preset starting power is controlled, can be so that power control effect becomes desirable more.
Such as the threshold coding mode when starting power control be MCS7 (translate among the Modulation andCoding Scheme 7: in the time of modulation coding mode 7), execution in step 204 when the coded system that gets access to is MCS7 or MCS8 or three coded systems of MCS9.
204. judge whether the transmission environment of channel is stable state;
If the transmission environment of channel is a stable state, then change step 205 over to.
And the transmission environment of judging channel whether be the mode of stable state can be with reference to the associated description in embodiment illustrated in fig. 1, below will be with the transmission environment of confirming channel according to coded system stable describing whether:
241. judge that the coded system whether coded system get access to get access to the last time is identical; If the coded system that gets access to is identical with the last coded system that gets access to, then change step 242 over to; If the coded system that gets access to is inequality with the last coded system that gets access to, then change step 243 over to.
Channel Transmission environment corresponding coding manner under the stable state generally is relatively-stationary, so this step can confirm whether starting power is controlled through the coded system that gets access to.The wherein the last coded system that gets access to is meant obtains this coded system recent coded system that gets access to before.With timeslot-level measurement report is example, can get access to each timeslot-level measurement report corresponding coding manner, according to the journal coded system information of the coded system that gets access to.
Need to prove that if the coded system that gets access to is for the first time, the then the last coded system that gets access to is the coded system of acquiescence.The coded system of general acquiescence is the minimum coded system MCS1 of numerical value.
242. the number of times to the same-code mode that gets access to is counted.
Here; Because the said coded system that gets access to is identical with the recent coded system that gets access to before; So the number of times to the said coded system that gets access to is counted, promptly record continuously which time get access to this coded system, and continue execution in step 241.When the number of times of the same-code mode that gets access to reaches preset targeted number, think that the transmission environment of channel is a stable state, execution in step 205.Wherein, targeted number is predefined thresholding number of times, can objective judgement Channel Transmission environment stable, the value of this targeted number can be set according to actual needs.
243. count results is carried out zero clearing to be handled.
Here according to step 241 because the coded system that gets access to is inequality with the recent coded system that gets access to before; So restart the number of times of the coded system that newly gets access to is counted; The execution zero clearing is handled, and changes step 201 and 242 over to and obtains coded system again and reach the same-code mode number of times that newly gets access to is counted.
205. when the transmission environment of channel is stable state, according to controlling said channel transmitting power with the pairing carrier/interface ratio of said coded system with the corresponding carrier/interface ratio of said measurement report.
When the transmission environment of judging the corresponding channel of the coded system that gets access to when step 204 was stable state, this step was according to can be through obtaining the corresponding carrier/interface ratio of said coded system and controlling the transmitting power of described down channel according to the corresponding carrier/interface ratio of measurement report.Concrete mode can repeat no more with reference to the associated description in embodiment illustrated in fig. 1 here.
206. the count results of the said coded system that gets access to is carried out zero clearing to be handled.
This step is after step 205;, a power control also can effectively carry out after accomplishing for next power control; Handle so can carry out zero clearing to the count results of the said coded system that gets access to here, just the count results that reaches targeted number is carried out zero clearing and handle.
Need to prove, in the present embodiment, can be after power control be accomplished again to the count results zero clearing of the coded system that gets access to, also can be to the count results zero clearing when receiving next measurement report; Perhaps also can other opportunitys to the count results zero clearing, present embodiment is not done qualification.

Can obtain the parameter in each measurement report according to what the BTS that receives sent to the corresponding measurement report of each reverse link traffic channel; Such as error rate parameter (MEAN_BEP and CV_BEP etc.); Can obtain each error rate corresponding coding manner according to the LA algorithm, thereby obtain each measurement report corresponding coding manner.
302. the magnitude relationship of the coded system thresholding of coded system that judgement gets access to and starting power control;
If the coded system that gets access to is not less than the coded system thresholding of starting power control, then change step 303 over to; Otherwise continue execution in step 301.
303. judge whether the transmission environment of channel is stable state;
If the transmission environment of channel is a stable state, then change step 304 over to.
And the transmission environment of judging channel whether be the mode of stable state can be with reference to the associated description in embodiment illustrated in fig. 1, below will be with the transmission environment of confirming channel according to coded system stable describing whether:
331. judge that the coded system whether coded system get access to get access to the last time is identical,, then change step 332 over to if the coded system that the coded system that gets access to and the last time get access to is identical; If the coded system that gets access to is inequality with the last coded system that gets access to, then change step 333 over to.
332. the number of times to the same-code mode that gets access to is counted.
333. count results is carried out zero clearing to be handled.
304. when the transmission environment of channel is stable state, according to controlling said channel transmitting power with the pairing carrier/interface ratio of said coded system with the corresponding carrier/interface ratio of said measurement report.
When the transmission environment of judging the corresponding channel of the coded system that gets access to when step 303 was stable state, this step was according to can be through obtaining the corresponding carrier/interface ratio of said coded system and controlling the transmitting power of described up channel according to the corresponding carrier/interface ratio of measurement report.Specifically can repeat no more with reference to the associated description in embodiment illustrated in fig. 1 here.305. the count results of the said coded system that gets access to is carried out zero clearing to be handled.
Step 302 in the present embodiment～305 are similar with step 203～206 among the embodiment before, are that report is analyzed to down-run survey among the embodiment before unique difference is, and according to analysis result BTS the down channel transmitting power of control controlled; And above-mentioned steps 301～305th, report is analyzed to out-hole run, and according to the analysis result terminal being controlled by the uplink channel transmission power of control; Because step 203～206 are being specified; So those skilled in the art can understand above-mentioned step to the control of up channel power according to above-mentioned explanation to downlink channel power control fully, repeat no more with the similar step 302 in step 203～206～307 to above-mentioned based on this present embodiment.
