Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
The structural representation of the HetNet network of a kind of LTE system that Fig. 1 provides for embodiments of the invention, network comprises small base station A, B and C and macro base station, described small base station can include but not limited to Pico, Femto and HeNB (Home eNB, Home eNodeB) etc.Macro base station coverage is larger, small base station A, B and C is made to be under the covering of macro base station A, when subscriber equipment is in small base station A coverage, equally under macro base station covers, therefore macro base station interference may be subject to, particularly when UE distance macro base station is nearer, disturb more serious.Only transmit in common subframe because macro base station does not transmit data in ABS subframe, therefore macro base station is less to the interference of small base station subordinate UE in ABS subframe.For UE, being positioned at phase subframe in the same time with the ABS subframe of macro base station is low interfering subframe.For ease of understanding, Fig. 2 gives a kind of contrast schematic diagram comprising macro base station subframe and subscriber equipment subframe that the embodiment of the present invention provides.Can see, the subframe of macro base station comprises ABS subframe and common subframe.Macro base station is synchronous with the frame of small base station and small base station subordinate UE.With the ABS subframe of macro base station be positioned at mutually in the same time be the low interfering subframe of UE, represent by white spaces in fig. 2.And the subframe of macro base station transceiving data is common subframe, with the common subframe of macro base station be positioned at mutually in the same time be the common subframe of UE, also referred to as the high interference subframe of UE, represent with black space in fig. 2.
Certainly, more than illustrate only for the ease of understanding, for UE, the disturbance regime difference of its different subframe is caused to have many reasons, but more common situation is by other node outside UE service node, and namely non-UE service node causes, such as, before described macro base station, or from the website that other overlaps on frequency domain with UE serving BS, the present embodiment does not limit this.But the interference that the interference source of some moment UE causes may be less, forms low interfering subframe.Except the ABS subframe of macro base station, with multicast broadcast single frequency network (the MB SFN of macro base station, Multicast/Broadcast Single FrequencyNetwork) the corresponding UE subframe of subframe also can think low interfering subframe, this is because macro base station MBSFN sub-frame does not form interference to adjacent small base station subordinate UE.The Crack cause of the present embodiment to low interfering subframe does not limit, as long as the interference that this UE is subject to non-UE service node in a certain specific sub-frame is less than the interference being subject to this non-UE service node in common subframe, then namely this specific sub-frame can be used as the low interfering subframe of UE.
Fig. 3 is the simple flow schematic diagram embodiments providing a kind of channel state information reporting method, and this flow process comprises:
S31: subscriber equipment receives the radio resource control signaling that service node sends, described radio resource control signaling comprises and reports configuration information, described in report configuration information to comprise to report interval Lcqi.
S32: described subscriber equipment according to described in report the instruction of configuration information, often perform Lcqi the instruction of the channel quality for low interfering subframe and measure and report, only perform and once measure for the channel quality instruction of common subframe and report.
Can effectively for the scene that there is heterogeneous networks unit and introducing time domain eICIC under heterogeneous network at the present embodiment, even if around interference environment makes not the interference that UE may exist in the same time vary in size, but UE is according to the subframe of disturbance type, different measurements is adopted to report frequency that the low subframe of annoyance level and common subframe are carried out to CQI measurement respectively and reported, the CQI of low interfering subframe is made to measure and report frequently, in the simultaneous system of multiple interference environment, improve the measurement of channel quality instruction and report precision, and make the CQI reported more accurately reflect channel conditions, improve and report precision.In the above-described embodiments, the sub-frame number in one group of low interfering subframe or one group of common subframe can be one or more.Report interval Lcqi can be the integer of a non-negative described in being appreciated that, described Lcqi be used to indicate and often measures through the CQI of Lcqi low interfering subframe and report, and the CQI performing once common subframe measures and reports.Lcqi can get 1, but to get the integer being greater than 2 be a kind of more common implementation.When Lcqi is 0, then the CQI showing not carry out common subframe measures and reports, and the CQI only performed for low interfering subframe measures and reports.
For ease of describing said process S32, be measured as example below with the CQI of the low interfering subframe to UE, introduction is carried out a CQI and is reported required flow process, and in this example, the low interfering subframe of UE corresponds to the ABS subframe of macro base station.Particularly, Fig. 4 gives a kind of schematic diagram performing a channel condition information measurement and report method that the embodiment of the present invention provides, assuming that UE current serving Node is a small base station, interference source may be macro base station, then the method comprises:
S41: for each UE, small base station, according to the ABS subframe type pattern of macro base station, determines that its measurement reports configuration information.Described measurement reports configuration information to comprise two parts: measure resource allocation information and report configuration information.Measuring resource allocation information can be binary bit diagram, by this bit diagram, subframe is divided into the subframe of two types, i.e. low interfering subframe and high interference subframe (common subframe).Alternatively, measuring resource allocation information here also can be the result of binary bits figure after coding, and the present embodiment does not limit this.Describedly report configuration information to can be used for instruction to report pattern.
S42: described measurement reports configuration information to UE by RRC signaling by small base station.
S43:UE obtains described measurement resource allocation information, identifies multiple with reference to the low interfering subframe in subframe and common subframe.Particularly, whether UE can to judge in described measurement resource allocation information with a value with reference to indicating bit corresponding to subframe is 1, when the value of described indicating bit is 1, determines that this reference subframe is low interfering subframe; When the value of described indicating bit is 0, determine that this reference subframe is common subframe.UE can after the described RRC signaling of reception, therefrom extract measurement and report configuration information, and the measurement resource allocation information REScqi_ref obtained wherein that decodes, the indicating bit corresponding with multiple subframe can be comprised in REScqi_ref, judge whether the indicator bit value corresponding to N+1 subframe between n-N-ncqi_ref to n-ncqi_ref is " 1 " respectively, here N is positive integer, and the subframe being " 1 " by all judged results forms low interfering subframe group; The subframe that judged result is " 0 " forms common subframe group.
Be appreciated that the present embodiment also can indicate a reference subframe to be low interfering subframe when the value of described indicating bit is 0; Indicate this reference subframe to be common subframe when the value of indicating bit is 1.Certainly, UE also only can determine low interfering subframe from multiple subframe, and remaining subframe is exactly common subframe naturally, and vice versa.
S44:UE can report pattern to measure in one group of low interfering subframe according to the described measurement reporting configuration information to indicate and obtain a CQI.
In order to improve CQI accuracy of measurement, by measuring the CQI of each low interfering subframe in low interfering subframe, and carry out low-pass filtering to measuring the multiple CQI obtained, the result of low-pass filtering is indicated as the first channel quality.Described low-pass filtering process is the equal of average to the CQI measurement of multiple low interfering subframe, and the first channel quality pointing accuracy obtained increases.
S45:UE reports a described CQI to described small base station.
Above-described embodiment describes a kind ofly to be measured and reports the implementation procedure of the CQI of low interfering subframe, and when needing the CQI obtained for common subframe, only need low interfering subframe to replace with common subframe, above-mentioned implementation procedure still uses.The present embodiment by distinguishing common subframe and low interfering subframe, the CQI of the subframe in once reporting under a kind of disturbed condition of Excelsior, can reduce for multiclass disturbance situation subframe hybrid measurement and report CQI to cause inaccurate.In embodiments of the present invention, for ease of introducing, if carried out at one-shot measurement with in reporting for low interfering subframe, then the CQI obtained is called a CQI; If carried out at one-shot measurement with in reporting for common subframe, then the CQI obtained is called the 2nd CQI, and this self-defined title is not used in restriction the present invention certainly.
In LTE system, because reporting of CQI exists time delay, the CQI of the corresponding witness mark resource of the reception of service node (as LPN etc.) in the n-th subframe of UE, particularly, the CQI of the current reception of service node is the CQI before ncqi_ref subframe, and ncqi_ref is a default positive integer.Specifically as shown in Figure 5, service node may receive in the n-th subframe the CQI that UE sends, consider the impact of reporting time delay, the witness mark subframe n-ncqi_ref corresponding to the n-th subframe can be determined, and using the CQI that receives in the n-th subframe CQI as witness mark subframe n-ncqi_ref.
In process S44, for improving certainty of measurement, can to the CQI filtering of multiple low interfering subframe.But in actual applications, when measuring any class subframe, also multiple same class subframe subframe can be carried out low-pass filtering and obtaining result to report, improve and report CQI precision.For ease of understanding, be described below in conjunction with accompanying drawing, as shown in Figure 6, there is multiple subframe for measuring the reference subframe of CQI in subscriber equipment, comprise subframe n-8, n-7 ..., n-4, comprising low interfering subframe and high interference subframe, represent by white and black space respectively.Filtering can be carried out to the CQI of the CQI of multiple low interfering subframe or multiple high interference subframe in a low-pass filtering window, namely the CQI mean value obtaining multiple low interfering subframe or multiple high interference subframe is equivalent to, and filter result can be reported to service node, the service node of UE at a time subframe (being presented at the n-th subframe in figure) can receive the filtered CQI reported, and determine the witness mark subframe corresponding with the current time of reception, thus determine that the CQI received is the CQI obtained based on which low interfering subframe or common subframe.
In figure 6, low interfering subframe CQI is CQI_LI=average (CQI (n-8), CQI (n-6)), the mean value of the low interfering subframe subframe n-8 and n-6 namely obtained after low-pass filtering; The CQI of high interference subframe is CQI_HI=average (CQI (n-7), CQI (n-5), CQI (n-4)), the common subframe n-7 namely obtained after low-pass filtering, the mean value of n-5 and n-4.If UE reports CQI_LI in this reports, service node can determine the CQI with reference to low interfering subframe in subframe accordingly; If UE reports CQI_HI in this reports, service node can determine the CQI with reference to high interference subframe in subframe accordingly.
Pass through above-described embodiment, at one-shot measurement and report in CQI process, be no matter this measure report process for be common subframe or low interfering subframe, all by adopt above-described embodiment realize, and to the CQI of multiple same interference type subframe carry out filtering be conducive to improve measure and report precision.
The schematic diagram of the another kind of channel state information reporting method that Fig. 7 provides for the embodiment of the present invention, the method comprises:
S71:UE receives the RRC signaling that service node sends, and described RRC signaling comprises and reports configuration information, described in report configuration information to comprise to report interval Lcqi.
S72: report interval Lcqi according to described, UE performs Lcqi the instruction of the channel quality for low interfering subframe and measures and report within Lcqi cycle, and report the moment to start to perform and once measure for the channel quality instruction of common subframe and report at the next one of described Lcqi all after dates, namely in this process for the 2nd CQI report cycle of low interfering subframe be for a CQI report cycle of common subframe Lcqi doubly.
In periodically reporting, a report cycle can complete a CQI and report, for reporting the CQI of a frequency band in reporting at this.A frequency band can be divided into multiple portions of bandwidth (BP, BandwidthPart), therefore the CQI of this frequency band can comprise the broadband CQI of this frequency band self and the subband CQI of its multiple portions of bandwidth, and each subband CQI may repeat to report repeatedly within the cycle.Fig. 8 be with Lcqi be 2, Np carries out brief description for 5ms, K equal 1 for example to periodically reporting, Np is for reporting time at intervals, and K is the number of repetition that subband reports.Suppose a CQI is reported, the system bandwidth measured is needed to be divided into 3 portions of bandwidth, then on frequency domain, a CQI comprises 1 broadband CQI (W-CQI, Wideband-CQI) and 3 subband CQI (S-CQI corresponding to different bandwidth part, Subband-CQI), therefore need to report 4 CQI in a report cycle of a CQI, so comprise 4 in the report cycle of a CQI to report the moment.In time domain, report interval between the moment identical, report moment Np interval 5ms in this example, 8 between 0 to 35ms engrave when reporting, report respectively and 2 take turns a CQI in other words 2 times within 2 cycles.For a CQI, W-CQI1, S-CQI1, S-CQI1, S-CQI1, W-CQI1, S-CQI1, S-CQI1 and S-CQI1 is reported successively within 2 cycles altogether, the wherein W-CQI1 subband CQI that to be the broadband CQI in a CQI, S-CQI1 be in a CQI.Subband CQI in actual applications in one-period can be repeatedly measured and report K time, and the number of repetition K reported due to subband measurement is in this example 1, and therefore in a report cycle, each subband CQI is only measured to be reported once.Report in this example broadband CQI front, report subband CQI rear, but this order can freely adjust in actual applications.After a CQI in continuous 2 cycles has reported, the moment can be reported to start to report the 2nd CQI at the next one arrived subsequently.That is, in this example, after the low interfering subframe CQI reporting 2 cycles, only report the high interference subframe CQI of one-period.Particularly, the 2nd CQI can comprise broadband CQI and subband CQI, also can only include broadband CQI.Therefore report situation for high interference subframe and low interfering subframe these two kinds, report content can be different, the report cycle of a CQI report cycle and the 2nd CQI also can be different.In fig. 8, the 2nd CQI only includes broadband CQI (W-CQI2), and therefore the 2nd CQI report cycle only includes one and reports the moment, but this citing is not used in restriction the present invention, and the 2nd CQI also can be configured to report more subband CQI as required.
Above embodiment is described to adopt periodic report pattern, when described report configuration information to indicate to adopt report pattern aperiodic time, can report according to the triggering of small base station.Particularly, UE after continuous Lcqi reception small base station triggers and report a CQI, can report the 2nd CQI when receiving triggering the Lcqi+1 time.That is, after low interfering subframe CQI is triggered and reports Lcqi time, only trigger and report a high interference subframe CQI.After being triggered, UE can several report the moment to report to small base station by needing broadband CQI of reporting and subband CQI subsequently at every turn.With describe before the same, because CQI can comprise broadband CQI and some subband CQI, thus once trigger report in CQI the CQI quantity needing to report can have multiple.Each triggering reports the CQI quantity that reports during a CQI can be different from the CQI quantity reported when triggering and report the 2nd CQI at every turn, namely for a CQI and the 2nd CQI, once reports shared duration can difference after being triggered.Certainly, if need to repeat to report subband CQI, in the report cycle after once triggering, subband CQI can be reported repeatedly, and the present embodiment does not limit this.
In the present embodiment, because the performance impact of launch and accept performance on whole system of low interfering subframe is greater than the impact of high interference on system, therefore increase low interference CQI report frequency be conducive to improve CQI report efficiency, and report process to launch according to the cycle, each cycle completes a CQI and reports, and each CQI reports content by one or more, to report pattern also can have multiple, all can be configured by those skilled in the art, and can by service node notifying user equipment.The content reported as CQI only has one, as only having the broadband CQI of a frequency band, then once reports and takies one and report the moment, and the content reported as CQI only has multiple, namely includes the subband CQI of frequency band, then this reports to take and multiplely reports the moment.Triggering reports can be similar with periodic report, reports at every turn and can report multiple CQI, and each CQI reports and can occupy one and report the moment.
Above-described embodiment can be out of shape further, the schematic diagram of the another kind of channel state information reporting method that Fig. 9 provides for the embodiment of the present invention, and the method comprises:
S91:UE receives the RRC signaling that service node sends, and described RRC signaling comprises and reports configuration information, described in report configuration information to comprise to report interval Lcqi and report position to offset NOFFSET2.
S92: report interval Lcqi according to described, UE performs the instruction of Lcqi channel quality for low interfering subframe and measures and report within Lcqi cycle, and starts to perform through the NOFFSET2 moment after a described Lcqi cycle and once measure for the channel quality instruction of common subframe and report.
For Lcqi be 2, Np for 5ms, K be 1, NOFFSET2 3 is described, supposing the system bandwidth is still divided into 3 portions of bandwidth (BP Bandwidth Part), on frequency domain, the CQI of this system bandwidth is made up of the subband CQI that 1 broadband CQI and 3 corresponds to different bandwidth part, 20ms is a CQI report cycle, reports 4 CQI in each CQI report cycle.After a CQI in continuous 2 cycles has reported, the 2nd CQI can be reported in NOFFSET2 the skew moment subsequently.Described NOFFSET2 is nonnegative integer, when NOFFSET2 gets 0, can represent and not report the 2nd CQI.Reference Figure 10 is example, and NOFFSET2 is 3, has reported a CQI in 2 cycles at 35ms, can report the broadband CQI (W-CQI2) of the 2nd CQI, and continue to report a CQI in next cycle at 38ms.That is, whenever reporting a CQI of 2 cycle periods, just inserting second CQI and reporting.The present embodiment reports not by the restriction reporting the moment due to the 2nd CQI's, can report according to a certain skew moment of the instruction of NOFFSET2 after a CQI report cycle completes, and reports more flexible, and increases reporting of low interfering subframe and be conducive to improving accuracy.
For the situation that aperiodicity reports, also can use for reference the method that above-mentioned insertion reports, UE reports CQI by the triggering receiving service node.Receive for Lcqi time to trigger and will described first channel quality index uploading extremely after described service node whenever UE is continuous, NOFFSET2 subframe after can receiving triggering starts by described second channel quality index uploading extremely described service node at the Lcqi time.That is, the 2nd CQI reports and need not receive independent triggering, but a certain skew moment after a CQI triggering reaches certain number of times carries out.The frequency be triggered due to a CQI be the Lcqi of the 2nd CQI doubly, be conducive to raising and report precision, and carry out reporting according to skew and save an additional triggers flow process.
Above-described embodiment can avoid the resource corresponding to CQI reported to have different interference environments, thus improve CQI report precision.Simultaneously, because the launch and accept performance of low interfering subframe will much larger than the impact of high interference on system on the performance impact of whole system, therefore ensureing under the prerequisite reporting load certain, improve for reporting low interfering subframe CQI always reporting the ratio in load, the efficiency measuring and report CQI can be improved, effectively improve systematic function.
