At third generation partner program (3GPP, 3rd Generation Partnership Project) R7 version is introduced multiple-input and multiple-output (MIMO, Multi Input Multi Output) after the technology, regulation subscriber equipment (UE, User Equipment) report the channel quality of following two classes to indicate (CQI, Channel Quality Indication):

1, type A (Type A) CQI:

If when UE felt to suit to use stream transmission, then Type A CQI was double-current CQI value (CQI1 and CQI2);

If UE feels to suit to use single-stream transmission, then Type A CQI is single current CQI value (CQIs);

Concrete UE judges that the suitable process of which kind of transmission means of using can be by the different strategy of each terminal manufacturer formulation, for example can be by comparing the transmission block size (TBS of single current CQI correspondence, Transport Block Size) corresponding with double-current CQI TBS determines that detailed process is not described in detail.

2, type B (Type B) CQI:

The CQI of the type need not UE and selects, and always reports single current CQI value by UE.

MIMO UE periodically alternately reports Type A CQI and Type B CQI, and the proportionate relationship of the two is stipulated that by parameter " type A ratio " this parameter is MIMO N_cqi type A/M_cqi, promptly represents the ratio that the CQI of Type A accounts in whole C QI.

In the prior art, when UE need use business, UE can send radio bearer to radio network controller and set up request RADIO BEARER SETUP REQUEST, radio network controller sends wireless connections to the base station and sets up request RADIO LINK SETUP REQUEST subsequently, wireless connections are set up in the base station, and set up response RADIO LINK SETUPRESPONSE to the wireless connections of radio network controller feedback, in this response, carry parameter " type A ratio ", radio network controller is set up response RADIO BEARER SETUP RESPONSE to UE feedback radio bearer, in this response, carry parameter " type A ratio " equally, after this, UE promptly uses this parameter " type A ratio " periodically alternately to report Type A CQI and Type B CQI.

In realizing process of the present invention, the inventor finds that above-mentioned prior art has following shortcoming at least:

Base station of the prior art can't be upgraded " type A ratio ", have only radio network controller to reshuffle to " type A ratio ", but radio network controller can't known the channel conditions that UE is using to " type A ratio " when reshuffling, so reshuffling that radio network controller carries out might not meet the current actual conditions of UE, thereby cause UE rationally to report CQI, therefore reduced systematic function according to actual conditions.

Embodiment

The embodiment of the invention provides a kind of method for controlling reporting of channel quality indicator, base station and subscriber equipment, in order to dynamic adjustment type A ratio, makes UE reasonably to report CQI according to actual conditions, thereby improves systematic function.

See also Fig. 1, the CQI method for controlling reporting in one embodiment of the invention can comprise:

101, the base station judges whether the buffer data size of UE reaches regularization condition, if reach, then execution in step 102;

In the present embodiment, the base station can judge whether the buffer data size of certain UE reaches the regularization condition that presets, and this buffer queue is preset in the base station from the buffer queue that preserve this locality, the corresponding buffer queue of each UE.

102, type A ratio is adjusted, described adjusted type A ratio is sent to UE, then UE reports CQI according to adjusted type A ratio.

When the buffer data size of UE reaches the regularization condition that presets, then can adjust type A ratio, and adjusted type A ratio is sent to UE according to the situation of the buffer data size of UE.

Need to prove that when the buffer data size of UE did not reach the regularization condition that presets, then the base station can not adjusted type A ratio, and carried out other operation, for example continue to carry out the communication operation undertaken the base station etc., qualification is not done in concrete operations herein.

By above-mentioned scheme as can be seen, in the present embodiment, the base station can judge whether the buffer data size of UE reaches the regularization condition that presets, when reaching the regularization condition that presets, then can adjust, and adjusted type A ratio is sent to UE, so the base station can dynamically be adjusted type A ratio type A ratio, make UE reasonably to report CQI, thereby improve systematic function according to actual conditions.

See also Fig. 2, the method that further embodiment of this invention provides a kind of CQI to report control, this method can comprise:

201, receive the channel quality indication that subscriber equipment sends;

The R7 version of 3GPP is introduced after the MIMO technology, and regulation UE reports Type A CQI and Type B CQI, and the base station can receive the CQI that UE sends, and this CQI represents the quality of channel that this UE is using.

202, the channel quality indicator (CQI) that sends according to user equipment (UE) judges whether current channel quality reaches the quality gate limit value that presets, if reach, then execution in step 204, if do not reach, then execution in step 203;

Current channel quality can be calculated according to this CQI in the base station after the CQI that receives the UE transmission, concrete computational process is prior art, does not limit herein.

The base station can be estimated current channel quality after calculating current channel quality, if current channel quality reaches the quality gate limit value that presets, then execution in step 204, if do not reach, then execution in step 203.

Suppose that default channel quality level has 5 grades, is respectively 0,1,2,3,4, channel quality reduces successively by 0 to 4, a quality gate limit value can be set according to demand, for example be set to 1, then when current quality of channel reaches 1 grade, can execution in step 204, if do not reach 1 grade (for example being 2 grades, 3 grades or 4 grades), then execution in step 203.

Need to prove that above-mentioned channel quality level only is a concrete example, in actual applications, other can also be set, do not limit herein in order to estimate the parameter of channel quality.

Quality gate limit value in the present embodiment can be set according to the actual requirements, can be empirical value, for example, can change according to this quality gate limit value of different situations, when promptly making channel quality preferably, execution in step 204, execution in step 203 when channel quality was bad.

203, treatment step and process ends are preset in execution;

In the present embodiment preset treatment step can for: continue to receive the CQI that UE reports, and continue to judge whether current channel quality reaches the quality gate limit value that presets.

Be understandable that in actual applications, this treatment step that presets can also be other step, for example " point out current channel quality bad, do not allow to adjust type A ratio " etc. that concrete processing mode does not limit herein.

Need to prove, if the buffer data size of subscriber equipment does not reach the regularization condition that presets in the step 204, then equally can execution in step 203, at this moment, step 203 can be " buffer data size adjustments that do not satisfy condition of prompting subscriber equipment do not allow to adjust type A ratio ", perhaps is other the step that presets, for example continue the buffer data size of supervisory user equipment, concrete steps do not limit herein.

204, whether the buffer data size of judging subscriber equipment reaches the regularization condition that presets, if then execution in step 205, if not, then execution in step 203;

In the present embodiment, in the base station, each subscriber equipment all has a buffer queue, store certain data volume in this buffer queue and be used for transmission, if this data volume abundance then uses the probability of MIMO stream transmission bigger, if this data volume deficiency, then use the probability of MIMO single-stream transmission bigger, therefore can judge whether and to adjust type A ratio by this data volume.

If determine that this data volume has satisfied the regularization condition that presets, then execution in step 205, do not satisfy the regularization condition that presets if determine this data volume, and then execution in step 203.

Need to prove, be whether the buffer data size of judging subscriber equipment when channel quality reaches the threshold value that presets reaches the regularization condition that presets in the present embodiment, be understandable that, in actual applications, be not necessary step to the judgement of channel quality, promptly after certain UE receives CQI, as long as the buffer data size of this UE reaches the regularization condition that presets, can adjust type A ratio, and need not to judge current channel quality, promptly need not execution in step 201 to step 203.

But, if when channel quality has reached the quality gate limit value (being that channel quality is relatively good) that presets, TypeA CQI mainly is double-current CQI, the numerical value of type A ratio carries out resource allocation to the base station at this moment bigger influence, therefore, in the present embodiment, by step 201-202, can be so that the distribution of base station to resource can be controlled more accurately to the adjustment of type A ratio in the base station.

205, type A ratio is adjusted;

If determined that data volume has satisfied the regularization condition that presets, then represent the buffer data size abundance of subscriber equipment, perhaps not enough, then can adjust type A ratio.

If the buffer data size abundance, then the base station can increase the value of type A ratio, allows UE report more Type A CQI.Because when the CQI value that the base station reports based on UE is carried out power resource allocation, what double-current CQI reported among the TypeA is timely more, the double-current power resource allocation of base station is also just reliable more, just pass Block Error Rate (IBLER, Initial Block Error Rate) just can be controlled in the suitable scope, user's throughput is also just high more.

If buffer data size is inadequate, then use the probability of MIMO single-stream transmission bigger, the base station can reduce the value of type A ratio, so that allow UE report a certain amount of Type B CQI, guarantee the promptness that single current CQI value reports, thereby improve the reliability of MIMO single current power resource allocation, IBLER just can be controlled in the suitable scope, promotes user's throughput.

Need to prove, in the base station, can preset a set of forming by several numerical value, when needs increase the value of type A ratio, then from this set, choose the big numerical value of value than current type A ratio, and current type A ratio increased to this numerical value, when needs reduce the value of type A ratio, then from this set, choose the little numerical value of value, and current type A ratio is reduced to this numerical value than current type A ratio;

Perhaps, can also in the base station, preset a step-length, this step-length can be a positive floating number, when needs increase the value of type A ratio, then the value with current type A ratio adds this step-length, when needs reduced the value of type A ratio, then the value with current type A ratio deducted this step-length.

Above-mentioned increase or the method that reduces the value of type A ratio only are several examples, in actual applications, can adopt other method to increase or reduce the value of type A ratio equally, do not do qualification herein.

206, adjusted type A ratio is sent to subscriber equipment.

After the base station is adjusted type A ratio, then adjusted type A ratio can be sent to UE, make UE to report corresponding CQI according to this adjusted type A ratio.

In the present embodiment, after the base station determines that current channel quality reaches the quality gate limit value that presets, can judge the buffer data size of UE, when this buffer data size reaches the regularization condition that presets, type A ratio is adjusted, and adjusted type A ratio is sent to UE, therefore the base station can dynamically be adjusted type A ratio, makes UE reasonably to report CQI according to actual conditions, thereby improves systematic function.

See also Fig. 3, the CQI that another embodiment of the present invention provides reports the method for control, and this method can comprise:

301～303, with a last embodiment in step 201 basic identical to step 203, repeat no more herein;

304, inquiry UE corresponding cache formation;

In the present embodiment, in the base station, each subscriber equipment all has a buffer queue, stores certain data volume in this buffer queue and is used for transmission.

The base station receives CQI from UE in step 301, then inquire about this UE corresponding cache formation in the base station in this step.

Need to prove, be whether the buffer data size of judging subscriber equipment when channel quality reaches the threshold value that presets reaches the regularization condition that presets in the present embodiment, be understandable that, in actual applications, be not necessary step to the judgement of channel quality, promptly after certain UE receives CQI, as long as the buffer data size of this UE reaches the regularization condition that presets, can adjust type A ratio, and need not to judge current channel quality, promptly need not execution in step 301 to step 303.

But, if when channel quality has reached the quality gate limit value (being that channel quality is relatively good) that presets, TypeA CQI mainly is double-current CQI, the numerical value of type A ratio carries out resource allocation to the base station at this moment bigger influence, therefore, pass through execution in step 301 to 302 in the present embodiment, can be so that the distribution of base station to resource can be controlled more accurately to the adjustment of type A ratio in the base station.

305, obtain the interior data volume of buffer queue;

After inquiring the UE corresponding cache formation that sends CQI, can calculate the data volume in this buffer queue.

306, judge whether this data volume is greater than or equal to first thresholding, perhaps is less than or equal to second thresholding, if then execution in step 307, if not, then execution in step 303;

In the present embodiment,,, therefore can judge whether and to adjust type A ratio by this data volume if this data volume deficiency then uses the probability of MIMO single-stream transmission bigger if this data volume abundance then uses the probability of MIMO stream transmission bigger.

In the present embodiment,, then can determine the buffer data size abundance, can increase type A ratio,, then can determine data cached quantity not sufficient, can reduce type A ratio if data volume is less than or equal to second thresholding if data volume is greater than or equal to first thresholding.

It is 500KB that first thresholding for example is set, second thresholding is 100KB, then when the data volume in the buffer queue of this UE during more than or equal to 500KB, when perhaps being less than or equal to 100KB, then need type A ratio is adjusted, promptly buffer data size satisfies the regularization condition that presets, if this data volume is greater than 100KB and less than 500KB, then can type A ratio not adjusted, promptly buffer data size does not satisfy the regularization condition that presets.

Above-mentioned explanation be first thresholding and second thresholding situation inequality, be understandable that, in actual applications, first thresholding can also be identical with second thresholding, first thresholding for example is set and second thresholding is 300KB, when data volume during greater than 300KB, then can determine the buffer data size abundance, when data volume during less than 300KB, then can determine data cached quantity not sufficient, when data volume equals 300KB, can determine that buffer data size is sufficient or not enough according to the rule that presets, concrete rule is determined by practical application, does not limit herein.

The concrete numerical value of the above-mentioned thresholding that adopts is instantiation, and other numerical value can also be set in actual applications as required, does not limit herein.

307, type A ratio is adjusted;

In the present embodiment, if the buffer data size abundance, then the base station can increase the value of type A ratio, allows UE report more Type A CQI.Because when the CQI value that the base station reports based on UE is carried out power resource allocation, what double-current CQI reported among the Type A is timely more, the double-current power resource allocation of base station is also just reliable more, just pass Block Error Rate (IBLER, Initial Block Error Rate) just can be controlled in the suitable scope, user's throughput is also just high more.

If buffer data size abundance, then use the probability of MIMO single-stream transmission bigger, the base station can reduce the value of type A ratio, so that allow UE report a certain amount of Type B CQI, guarantee the promptness that single current CQI value reports, thereby improve the reliability of MIMO single current power resource allocation, IBLER just can be controlled in the suitable scope, promotes user's throughput.

Need to prove, in the present embodiment, can specifically can select numerical value for type A ratio is provided with some in advance, for example can be set to (1/2,2/3,3/4,4/5,5/6,6/7,7/8,1), concrete type A ratio can be selected in the numerical value selected at these 8, is understandable that, here the numerical value selected of She Zhiing only is instantiation, in actual applications, what are set can select numerical value, and specifically can select the value of numerical value all can be rule of thumb, or the condition of practical application determines, do not limit herein.

Whether the buffer data size that can determine current UE by above-mentioned steps 306 is sufficient, if sufficient, then can increase type A ratio, supposes that original type A ratio is 3/4, then when buffer data size is sufficient, can rise to 4/5; If data cached quantity not sufficient then can reduce type A ratio, suppose that original type A ratio is 3/4, then when data cached quantity not sufficient, can be reduced to 2/3.

308, adjusted type A ratio is placed in High-Speed Shared Control Channel (HS-SCCH, the High Speed Shared Control Channel) order (order);

In the present embodiment, the base station can be arranged at adjusted type A ratio among the HS-SCCH order, and the concrete class Order type that can increase newly in HS-SCCH order represents the type A ratio:

Order type xodt1, xodt2, the 3bit numerical value that xodt3=' 001 or other are not used at present ';

Order information xord1, xord2, xord3 represents 1/2,2/3,3/4,4/5,5/6,6/7,0～7index of 7/8,1/1 correspondence.

In the present embodiment, be the expression floating number, the type that order then is set is 3 bits, is specifically as follows 001, or other 3 bit value that are not used in 3GPP 25.212 agreements, then can carry type A ratio in HS-SCCH order.

309, send this HS-SCCH order to UE.

The base station can send a HS-SCCH order every 2 milliseconds to UE by HS-SCCH, and then the base station can be sent to UE with the HS-SCCH order that carries adjusted type A ratio, so that UE reports CQI according to this adjusted type A ratio.

Need to prove, be with the carrier of HS-SCCH order in the present embodiment as type A ratio, thereby adjusted type A ratio is sent to UE, is understandable that, in actual applications, be not limited to use the carrier of HS-SCCH order as type A ratio, can use other similar orders equally,, and should adjusted type A ratio be sent to UE and get final product as long as can carry adjusted type A ratio, the type of specific instructions does not limit herein.

In the present embodiment, the base station can directly send HS-SCCH order or other similar message of carrying adjusted type A ratio to UE, be understandable that, in actual applications, the base station can send the message of carrying adjusted type A ratio to UE by radio network controller or other network elements equally, and concrete type of message is not done qualification herein.

In the present embodiment, the base station can also judge whether the variable quantity of current channel quality reaches the threshold value that presets according to the CQI that receives from UE in the step 301, if reach, then can reduce the CQI report cycle, if do not reach, then can increase the CQI report cycle.

Wherein, the variable quantity of channel quality reaches the threshold value that presets and represents that then channel quality change frequency in the cycle of presetting is many, fluctuating range is bigger, be that variations is violent, instability so can reduce the CQI report cycle, makes UE report CQI more frequent, thereby help improving efficiency of resource distribution, promote cell capacity;

The variable quantity of channel quality does not reach the threshold value that presets and represents that then channel quality change frequency in the cycle of presetting is fewer, fluctuating range is smaller, be that channel quality is more stable, so can increase the CQI report cycle, make UE report the interval between the CQI bigger, thereby help reducing ascending load.

Further embodiment of this invention provides a kind of CQI method for controlling reporting, the difference of present embodiment and last embodiment is: last embodiment adopts the absolute figure of buffer data size to judge, adopt the ratio of the current transmission rate of buffer data size and UE to judge in the present embodiment, particularly, see also Fig. 4, the CQI method for controlling reporting in the embodiment of the invention can comprise:

401～403 with previous embodiment in 301～303 basic identical, repeat no more herein.

404, the current transmission rate of UE is obtained in inquiry UE corresponding cache formation;

The base station receives CQI from UE in step 401, then inquire about this UE corresponding cache formation in the base station in this step.

Simultaneously, the base station can also obtain the current transmission rate of UE, and concrete acquisition process is a prior art, does not limit herein.

Need to prove, be whether the buffer data size of judging subscriber equipment when channel quality reaches the threshold value that presets reaches the regularization condition that presets in the present embodiment, be understandable that, in actual applications, be not necessary step to the judgement of channel quality, promptly after certain UE receives CQI, as long as the buffer data size of this UE reaches the regularization condition that presets, can adjust type A ratio, and need not to judge current channel quality, promptly need not execution in step 401 to step 403.

But, if when channel quality has reached the quality gate limit value (being that channel quality is relatively good) that presets, TypeA CQI mainly is double-current CQI, the numerical value of type A ratio carries out resource allocation to the base station at this moment bigger influence, therefore, pass through execution in step 401 to 402 in the present embodiment, can be so that the distribution of base station to resource can be controlled more accurately to the adjustment of type A ratio in the base station.

405, obtain data volume in the buffer queue, with the ratio of data volume and current transmission rate as the measurement parameter;

After inquiring the UE corresponding cache formation that sends CQI, can calculate the data volume in this buffer queue, and with the ratio of data volume and current transmission rate as the measurement parameter.

406, judge whether this measurement parameter is greater than or equal to the 3rd thresholding, perhaps is less than or equal to the 4th thresholding, if then execution in step 407, if not, then execution in step 403;

In the present embodiment, be greater than or equal to the 3rd thresholding, then can determine the buffer data size abundance, can increase type A ratio, be less than or equal to the 4th thresholding, then can determine data cached quantity not sufficient, can reduce type A ratio if weigh parameter if weigh parameter.

It is 5 seconds that the 3rd thresholding for example is set, the 4th thresholding is 1 second, and the transmission rate of UE is 100KB/S, then when the data volume in the buffer queue of this UE during more than or equal to 500KB, weigh parameter more than or equal to 5 seconds, when the data volume in the buffer queue of this UE is less than or equal to 100KB, weigh parameter and be less than or equal to 1 second, promptly weigh parameter more than or equal to 5 seconds, then need when perhaps being less than or equal to 1 second type A ratio is adjusted, be that buffer data size satisfies the regularization condition that presets, if this data volume is greater than 100KB and less than 500KB, then weigh parameter between 1 second to 5 seconds, can type A ratio not adjusted, promptly buffer data size does not satisfy the regularization condition that presets.

Above-mentioned explanation be the 3rd thresholding and the 4th thresholding situation inequality, be understandable that, in actual applications, the 3rd thresholding can also be identical with the 4th thresholding, the 3rd thresholding for example is set and the 4th thresholding is 3 seconds, when data volume during greater than 300KB, weigh parameter greater than 3 seconds, then can determine the buffer data size abundance, when data volume during less than 300KB, weigh parameter less than 3 seconds, then can determine data cached quantity not sufficient, when data volume equals 300KB, weigh parameter and equal 3 seconds, can determine that buffer data size is sufficient or not enough according to the rule that presets, concrete rule is determined by practical application, does not limit herein.

407～409 with previous embodiment in 307～309 identical, repeat no more herein.

In the present embodiment, the base station can also judge whether the variable quantity of current channel quality reaches the threshold value that presets according to the CQI that receives from UE in the step 401, if reach, then can reduce the CQI report cycle, if do not reach, then can increase the CQI report cycle.

Above content be described from the angle of base station process dynamic adjustment type A ratio, angle from UE is described the processing mode that UE receives adjusted type A ratio below, see also Fig. 5, the CQI method for controlling reporting in yet another embodiment of the invention comprises:

501 receive the high-speed shared control channel command that the base station sends;

In the present embodiment, UE can receive the HS-SCCH order that includes adjusted type A ratio from the base station, is understandable that, UE can receive adjusted type A ratio by other similar command equally, and specific instructions does not limit herein.

502, obtain the type A ratio that comprises in the described high-speed shared control channel command;

Include the adjusted type A ratio in base station among the HS-SCCH order in the present embodiment, then UE can read type A ratio from this HS-SCCH order.

503, according to the described type A ratio of obtaining to described base station reporting channel quality indicator (CQI).

In the present embodiment, can also further comprise the CQI report cycle among the HS-SCCH order that UE sends, this CQI report cycle is that the base station is determined according to current channel quality, the base station of describing among the process that the CQI report cycle is determined in concrete base station and the preceding method embodiment determines that the process of CQI report cycle is consistent, repeats no more herein.

When UE gets access to the CQI report cycle from HS-SCCH order after, can report CQI according to this CQI report cycle.

In the present embodiment,, can adopt the type A ratio that the type A ratio of original local storage is upgraded, thereby use adjusted type A ratio to report CQI because UE has got access to adjusted type A ratio.In addition, UE might not upgrade original type A ratio, and for example UE can store a plurality of type A ratios simultaneously, as long as can make UE report CQI according to adjusted type A ratio.Therefore UE can reasonably report CQI according to actual conditions, thereby improves systematic function.

In further embodiment of this invention, the base station can be by HS-SCCH order directly to UE transmission types A ratio, and as shown in Figure 6, this method can comprise:

601, obtain type A ratio;
