Embodiment
To combine the accompanying drawing in the embodiment of the invention below, the technical scheme in the embodiment of the invention is carried out clear, intactly description, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the present invention's protection.
The structural representation of the HetNet network of a kind of LTE system that Fig. 1 provides for embodiments of the invention; Comprise small base station A, B and C and macro base station in the network; Said small base station can include but not limited to Pico, Femto and HeNB (Home eNB, Home eNodeB) etc.The macro base station coverage is bigger; Make small base station A, B and C be under the covering of macro base station A; In the time of in subscriber equipment is in small base station A coverage, under macro base station covers, therefore possibly receives macro base station and disturb equally; Particularly when UE is nearer apart from macro base station, disturb more serious.Because macro base station does not transmit data and only on common subframe, transmits on the ABS subframe, so macro base station is less to the interference of small base station subordinate UE on the ABS subframe.For UE, the subframe that is positioned at the identical moment with the ABS subframe of macro base station is low interfering subframe.For ease of understanding, Fig. 2 has provided a kind of contrast sketch map that comprises macro base station subframe and subscriber equipment subframe that the embodiment of the invention provides.Can see that the subframe of macro base station comprises ABS subframe and common subframe.The frame of macro base station and small base station and small base station subordinate UE is synchronous.What be positioned at the identical moment with the ABS subframe of macro base station is the low interfering subframe of UE, in Fig. 2, representes with white spaces.And the subframe of macro base station transceive data is common subframe, and what be positioned at the identical moment with the common subframe of macro base station is the common subframe of UE, is also referred to as the high interference subframe of UE, in Fig. 2, representes with the black space.
Certainly, more than be merely for example and be convenient to understand, for UE; Cause the disturbance regime difference of its different subframes to have multiple reason; But more common situation is that promptly non-UE service node causes by other outer node of UE service node, for example before described macro base station; Perhaps from other and the website that the UE serving BS overlaps on frequency domain, present embodiment does not limit this.But the interference that the interference source of some moment UE causes maybe be less, forms low interfering subframe.Except the ABS subframe of macro base station; Multicast broadcast single frequency network (MB SFN with macro base station; Multicast/Broadcast Single Frequency Network) the corresponding UE subframe of subframe also can be thought low interfering subframe, and this is because macro base station MBSFN subframe does not form interference to adjacent small base station subordinate UE.Present embodiment is not done qualification to the formation reason of low interfering subframe; As long as less than the interference that on common subframe, receives this non-UE service node, then this specific sub-frame promptly can be used as the low interfering subframe of UE to this UE in the interference that receives non-UE service node on a certain specific sub-frame.
Fig. 3 provides a kind of simplification schematic flow sheet of channel condition information report method for the embodiment of the invention, and this flow process comprises:
S31: subscriber equipment receives the radio resource control signaling that service node sends, and comprises in the said radio resource control signaling reporting configuration information, saidly reports configuration information to comprise to report Lcqi at interval.
S32: said subscriber equipment is according to the said indication that reports configuration information, and every execution is directed against the channel quality indication measurement of low interfering subframe Lcqi time and reports, and only execution once is directed against the channel quality indication measurement of common subframe and reports.
Can be at present embodiment effectively to having heterogeneous networks unit and the scene of introducing time domain eICIC under the heterogeneous network; Even if the interference environment interference that makes different UE constantly to exist on every side varies in size; But UE is according to the subframe of different interference types, adopts different measurement and report frequencies that the low subframe of annoyance level and common subframe are carried out CQI respectively and measures and report, and makes the CQI of low interfering subframe measure and reports more frequent; In the simultaneous system of multiple interference environment; Improve the measurement of channel quality indication and report precision, and make the CQI that reports more accurately reflect channel conditions, raising reports precision.In the above-described embodiments, the sub-frame number in one group low interfering subframe or the one group of common subframe can be for one or more.Be appreciated that saidly to report at interval that Lcqi can be a non-negative integer, said Lcqi is used to indicate every CQI through Lcqi low interfering subframe to measure and reports, and the CQI that carries out once common subframe measures and reports.Lcqi can get 1, but the integer of getting greater than 2 is a kind of more common implementation.When Lcqi is 0, show that then the CQI that does not carry out common subframe measures and reports, only carry out CQI to low interfering subframe and measure and report.
For ease of describing said process S32, be measured as example with CQI below to the low interfering subframe of UE, introduce and carry out a CQI and report needed flow process, in this example, the low interfering subframe of UE is corresponding to the ABS subframe of macro base station.Particularly, Fig. 4 has provided a kind of sketch map of carrying out a channel condition information measurement and report method that the embodiment of the invention provides, and supposes that UE current service node is a small base station, and interference source possibly be a macro base station, and then this method comprises:
S41: small base station is confirmed its measurement and report configuration information according to the ABS subframe type pattern of macro base station to each UE.Said measurement and report configuration information can comprise two parts: measure resource allocation information and report configuration information.Measuring resource allocation information can be binary bit diagram, is divided into the subframe of two types, promptly low interfering subframe and high interference subframe (common subframe) to subframe through this bit diagram.Alternatively, measuring resource allocation information here also can be the result behind the binary bits figure process coding, and present embodiment is not done qualification to this.The said configuration information that reports can be used for indicating the pattern that reports.
S42: small base station through the RRC signaling with said measurement and report configuration information to UE.
S43:UE obtains said measurement resource allocation information, identifies a plurality of with reference to low interfering subframe in the subframe and common subframe.Particularly, whether UE can judge in said measurement resource allocation information with a value with reference to the corresponding indicating bit of subframe is 1, when the value of said indicating bit is 1, confirms and should be low interfering subframe with reference to subframe; When the value of said indicating bit is 0, confirm to be common subframe with reference to subframe.UE can be after receiving said RRC signaling; Therefrom extract the measurement and report configuration information; And decoding obtains measurement resource allocation information REScqi_ref wherein, in REScqi_ref, can comprise the indicating bit corresponding with a plurality of subframes, and whether the pairing indicator bit value of N+1 sub-frame between judging respectively from n-N-ncqi_ref to n-ncqi_ref is " 1 "; Here N is a positive integer, is the low interfering subframe group of subframe composition of " 1 " with all judged results; Judged result is formed common subframe group for the subframe of " 0 ".
Be appreciated that present embodiment also can be that one of indication in 0 o'clock is low interfering subframe with reference to subframe in the value of said indicating bit; Value at indicating bit is that indication in 1 o'clock should be common subframe with reference to subframe.Certainly, UE also can only determine low interfering subframe from a plurality of subframes, and remaining subframe is exactly common subframe naturally, and vice versa.
S44:UE can measure a CQI according to the said measurement and report pattern of configuration information indication that reports on one group low interfering subframe.
In order to improve the CQI accuracy of measurement, can be through measuring the CQI of each low interfering subframe in the low interfering subframe, and a plurality of CQI that measure are carried out LPF, the result of LPF is indicated as first channel quality.Said LPF process is the equal of that the CQI measurement result of a plurality of low interfering subframe is averaged, and the first channel quality pointing accuracy that obtains increases.
S45:UE reports a said CQI to said small base station.
The foregoing description has been introduced a kind of implementation procedure of measuring and reporting the CQI of low interfering subframe, when needs are obtained the CQI that is directed against common subframe, only needs to hang down interfering subframe and replaces with common subframe, and above-mentioned implementation procedure is still used.Present embodiment is through distinguishing common subframe and low interfering subframe, and the CQI of the subframe during once reporting under a kind of disturbed condition of Excelsior can reduce to the subframe hybrid measurement of multiclass difference disturbed conditions and reports inaccurate that CQI causes.In embodiments of the present invention, for ease of introducing, if carry out to low interfering subframe at one-shot measurement with in reporting, the CQI that then obtains is called a CQI; If carry out to common subframe at one-shot measurement with in reporting, the CQI that then obtains is called the 2nd CQI, and this self-defined title is not used in qualification the present invention certainly.
In the LTE system; Because there is time-delay in reporting of CQI, the CQI of the reception corresponding witness mark resource of the service node of UE (like LPN etc.) on the n sub-frame, particularly; The CQI of the current reception of service node is the CQI before the ncqi_ref sub-frame, and ncqi_ref is a positive integer of presetting.Specifically as shown in Figure 5; Service node possibly receive the CQI that UE sends in the n subframe; Consider the influence of reporting time delay, can confirm the pairing witness mark subframe of n subframe n-ncqi_ref, and the CQI that will on the n subframe, receive is as the CQI of witness mark subframe n-ncqi_ref.
In process S44, for improving certainty of measurement, can be to the CQI filtering of a plurality of low interfering subframe.But in practical application, when any one type of subframe is measured, also can a plurality of same type subframe subframes be carried out LPF and obtain the result and report, improve and report the CQI precision.For ease of understanding, describe below in conjunction with accompanying drawing, as shown in Figure 6; Subscriber equipment exists a plurality of subframes to be used to measure the reference subframe of CQI; Comprise subframe n-8, n-7 ..., n-4, comprising low interfering subframe and high interference subframe, represent with white and black space respectively.In a LPF window, can carry out filtering to the CQI of a plurality of low interfering subframe or the CQI of a plurality of high interference subframes; Promptly be equivalent to obtain the CQI mean value of a plurality of low interfering subframe or a plurality of high interference subframes; And can filtered be reported to service node; The service node of UE is at a time received the filtered CQI that reports on the subframe (being presented at the n subframe among the figure); And confirm the witness mark subframe corresponding, thereby confirm that which the CQI that receives is based on and hangs down the CQI that interfering subframe or common subframe obtain with the current time of reception.
In Fig. 6, low interfering subframe CQI is CQI_LI=average (CQI (n-8), CQI (n-6)), low interfering subframe subframe n-8 that promptly obtains behind the process LPF and the mean value of n-6; The CQI of high interference subframe is CQI_HI=average (CQI (n-7), CQI (n-5), CQI (n-4)), the mean value of common subframe n-7, n-5 and the n-4 that promptly obtains behind the process LPF.If UE reports CQI_LI in this reports, service node can be confirmed the CQI with reference to low interfering subframe in the subframe in view of the above; If UE reports CQI_HI in this reports, service node can be confirmed the CQI with reference to high interference subframe in the subframe in view of the above.
Pass through the foregoing description; One-shot measurement with report in the CQI process; What no matter be that this measurement and report process is directed against is common subframe or low interfering subframe; All can realize, and the CQI of a plurality of same interference type subframes is carried out filtering help improving and measure and report precision through adopting the foregoing description.
The sketch map of the another kind of channel condition information report method that Fig. 7 provides for the embodiment of the invention, this method comprises:
S71:UE receives the RRC signaling that service node sends, and comprises in the said RRC signaling reporting configuration information, saidly reports configuration information to comprise to report Lcqi at interval.
S72: according to the said Lcqi at interval that reports; UE in Lcqi cycle, carry out Lcqi time to the channel quality indication measurement of low interfering subframe with report; And the next one of said Lcqi all after dates report constantly begin to carry out once to the channel quality indication measurement of common subframe with report, in this process, be doubly promptly to the Lcqi of a CQI report cycle of common subframe to the 2nd CQI report cycle of low interfering subframe.
In periodically reporting, a report cycle can be accomplished a CQI and report, and is used for reporting at this CQI of a frequency band.A frequency band can be divided into a plurality of portions of bandwidth (BP, Bandwidth Part), so the CQI of this frequency band can comprise the broadband CQI of this frequency band self and the subband CQI of its a plurality of portions of bandwidth, and each subband CQI may repeat to report repeatedly in the cycle.Fig. 8 be with Lcqi be 2, Np is 5ms, K equals 1 and carries out brief description for example to periodically reporting, Np is for reporting time at intervals, K is the number of repetition that subband reports.Suppose to report for a CQI; The system bandwidth that needs to measure is divided into 3 portions of bandwidth; Then on the frequency domain scope CQI comprise 1 broadband CQI (W-CQI, Wideband-CQI) with 3 subband CQI corresponding to different bandwidth part (S-CQI, Subband-CQI); Therefore in the report cycle of a CQI, need report 4 CQI, so comprise in the report cycle of a CQI that 4 report constantly.On time domain, report that constantly interbody spacer is identical, report constantly Np 5ms at interval in this instance,, 0 between 35ms 8 engrave when reporting, and in 2 cycles, report respectively and 2 take turns a CQI in other words 2 times.For a CQI; Report W-CQI1, S-CQI1, S-CQI1, S-CQI1, W-CQI1, S-CQI1, S-CQI1 and S-CQI1 successively in 2 cycles altogether; Wherein W-CQI1 is the broadband CQI among the CQI, and S-CQI1 is the subband CQI among the CQI.Subband CQI in practical application in the one-period can be repeated to measure and report K time, because the number of repetition K of subband measurement and report is 1 in this example, therefore in a report cycle, each subband CQI is only measured to be reported once.Report in this instance broadband CQI preceding, report subband CQI after, but this order can freely be adjusted in practical application.After a CQI in continuous 2 cycles reports completion, can report at the next one that arrives subsequently constantly to begin to report the 2nd CQI.That is to say, in this example, behind the low interfering subframe CQI that reports 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 include only broadband CQI.Therefore report situation for these two kinds for high interference subframe and low interfering subframe, report the content can be different, the report cycle of a CQI report cycle and the 2nd CQI also can be different.Therefore in Fig. 8, the 2nd CQI includes only broadband CQI (W-CQI2), and the 2nd CQI report cycle includes only one and reports constantly, but thisly is not used in qualification the present invention for example, and the 2nd CQI also can be configured as required and report more subband CQI.
Above embodiment is that example describes to adopt the periodic report pattern,, can report according to the triggering of small base station when reporting the configuration information indication to adopt to report pattern aperiodic when said.Particularly, UE can report the 2nd CQI when receiving triggering the Lcqi+1 time after receiving the small base station triggering continuously for Lcqi time and reporting a CQI.That is to say, whenever low interfering subframe CQI be triggered report Lcqi time after, only trigger and report high interference subframe CQI one time.After being triggered, UE can be in that several report broadband CQI and subband CQI of constantly needs being reported to report to small base station subsequently at every turn.With describe before the same because CQI can comprise broadband CQI and some subband CQI, so report the CQI quantity that need report among the CQI can have a plurality of in triggering once.Each trigger the CQI quantity that reported when reporting a CQI with each trigger the CQI quantity that is reported when reporting the 2nd CQI can be different, promptly for a CQI and the 2nd CQI, after being triggered, once report the shared duration can difference.Certainly, repeat to report subband CQI if desired, subband CQI can be reported repeatedly in the report cycle after once triggering, and present embodiment is not done qualification to this.
In the present embodiment because the emission receptivity of low interfering subframe is greater than the influence of high interference to system to the performance impact of whole system, therefore increase the low CQI of interference report frequency to help improving CQI to report efficient; And report process to launch according to the cycle; Each accomplishes a CQI and reports in cycle, and each CQI reports the content can be by one or more, and it is multiple to report pattern also can have; All can dispose by those skilled in the art, and can be by the service node notifying user equipment.When the content that CQI reports has only one, as have only the broadband CQI of a frequency band, then once report to take one and report constantly, the content that reports as CQI has only a plurality of, has promptly comprised the subband CQI of frequency band, and then this reports and takies a plurality of reporting constantly.Triggering reports can be similar with periodic report, reports to report a plurality of CQI at every turn, and each CQI reports and can occupy one and report constantly.
The foregoing description can be out of shape further, the sketch map of the another kind of channel condition information report method that Fig. 9 provides for the embodiment of the invention, and this method comprises:
S91:UE receives the RRC signaling that service node sends, and comprises in the said RRC signaling reporting configuration information, saidly reports configuration information to comprise to report at interval Lcqi and reports offset NOFFSET2.
S92: according to the said Lcqi at interval that reports; UE in Lcqi cycle, carry out Lcqi time to the channel quality indication measurement of low interfering subframe with report, and begin to carry out once to the channel quality indication measurement of common subframe constantly through NOFFSET2 after the cycle and report at said Lcqi.
With Lcqi be 2, Np is that 5ms, K are 1, NOFFSET2 is 3 to be that example describes; The supposing the system bandwidth still is divided into 3 portions of bandwidth (BP Bandwidth Part); The CQI of this system bandwidth is made up of 1 broadband CQI and 3 subband CQI corresponding to the different bandwidth part on the frequency domain scope; 20ms is one the one a CQI report cycle, reports 4 CQI in each CQI report cycle.After a CQI in continuous 2 cycles reports completion, can report the 2nd CQI constantly in NOFFSET2 skew subsequently.Said NOFFSET2 is a nonnegative integer, when NOFFSET2 gets 0, can represent not report the 2nd CQI.With reference to Figure 10 is example, and NOFFSET2 is 3, and the CQI in that 35ms has reported 2 cycles can report the broadband CQI (W-CQI2) of the 2nd CQI at 38ms, and in next cycle, continue to report a CQI.That is to say,, just insert one time second CQI and report whenever a CQI who reports 2 cycle periods.Present embodiment can report according to a certain skew of indication after a CQI report cycle is accomplished of NOFFSET2 because reporting of the 2nd CQI do not receive to report restriction constantly constantly, reports more flexibly, and increases and hangs down reporting of interfering subframe and help improving accuracy.
For the situation that aperiodicity reports, also can use for reference the method that above-mentioned insertion reports, UE can report CQI through the triggering that receives service node.Whenever UE is continuous receive to trigger for Lcqi time and will said first channel quality index uploading to said service node after, begin on can the NOFFSET2 sub-frame after receiving triggering the Lcqi time said second channel quality index uploading said service node extremely.That is to say that the 2nd CQI reports and needn't receive independent triggering, but constantly carry out in a certain skew that a CQI triggers after reaching certain number of times.Since the frequency that is triggered of a CQI be the 2nd CQI Lcqi doubly, help improving and report precision, and report according to skew and to have saved the additional triggers flow process one time.
The pairing resource of CQI that the foregoing description can be avoided reporting has different interference environments, thereby improves the precision that reports of CQI.Simultaneously; Because the emission receptivity of low interfering subframe will be much larger than the influence of high interference to system to the performance impact of whole system; Therefore guaranteeing to report under the certain prerequisite of load; Improve and to be used for reporting low interfering subframe CQI, can improve the efficient of measuring and reporting CQI, effectively improve systematic function always reporting the ratio of load.
