Embodiment
In order to make the object, technical solutions and advantages of the present invention clearly, below in conjunction with accompanying drawing, the present invention is described in further detail, and 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 other embodiments all obtained under creative work prerequisite, belong to the scope of protection of the invention.
Below in conjunction with Figure of description, the embodiment of the present invention is described in further detail.
The scene of reference Fig. 1 is to discuss the specific implementation process in the embodiment of the present invention better, and Fig. 1 is a scene example, under obvious technical scheme of the present invention can be applied to any scene of grand micro-interference in heterogeneous network.
As shown in Figure 1, coverage and macro station M1, the M2 of micro-station P2 and micro-station P1 exist and cover crossover region, in the P2 coverage of micro-station, one have UE1 ~ UE10 totally ten treat dispatch terminal, wherein, UE4 is in the covering crossover region of macro station M1 and M2.Micro-station P2 can receive the ABS pattern that macro station M1, M2 send, usual macro station M1, M2 send ABS pattern in ABS subframe position and ABS number of sub-frames not identical, micro-station P2 can adopt the following two kinds mode to determine the ABS pattern of micro-station P2, is the ABS subframe treating dispatch terminal distribution use under micro-station P2.Method one: the ABS pattern that common factor obtains micro-station is got to the ABS subframe in the ABS pattern of each macro station received, the method does not still send data not belonging in the ABS subframe in intersection range by making macro station, and micro-station does not use these subframes to carry out the scheduling of resource of interference user yet, cause the waste of macro station resource to a certain extent; Method two: the ABS pattern that union obtains micro-station is got to the ABS subframe in the ABS pattern of the multiple macro stations received, in the method, micro-station make use of all ABS subframes that macro station issues, but interference that dispatch terminal is subject to is not considered to treat from macro station still from other micro-stations in micro-station, and do not distinguish yet and treat that dispatch terminal is subject to the interference of which macro station, micro-station probably mistake will by the user scheduling of other micro-station interference in ABS subframe, or in the ABS subframe that the terminal scheduling by macro station M1 interference is distributed to macro station M2.The method can not play the object of grand micro-interference coordination well, the real performance improved by grand interference user, and is not used the wasting of resources still causing macro station targetedly due to macro station ABS subframe.
Embodiments provide another kind of resource regulating method based on the problems referred to above, as shown in Figure 2, comprise the following steps:
Step 201, according to treating the channel quality parameter that dispatch terminal reports, treat described in determining dispatch terminal whether for micro-station edge customer and described in treat dispatch terminal whether by the interference of adjacent macro station;
Step 202, if described in treat that dispatch terminal is the edge customer at micro-station and by the interference of adjacent macro station, then determines the interference macro station set treating dispatch terminal described in disturbing;
Step 203, according to the almost blank subframe ABS pattern that each macro station in the interference macro station set received sends, treats the ABS subframe that dispatch terminal uses described in determining.
Specifically, in above-mentioned steps 201, treat that the channel quality parameter that dispatch terminal reports can be Reference Signal Received Power (RSRP, ReferenceSignalReceivedPower) or Signal to Interference plus Noise Ratio (SINR, SignaltoInterferenceplusNoiseRatio) or other can characterize the parameter treating dispatch terminal channel quality.In addition, under different systems, the statement characterizing the parameter of channel quality is also different, as at LTE (LongTermEvolution, Long Term Evolution) middle finger be exactly RSRP value, at 3G (3rd-Generation) network middle finger is exactly received signal code power (RSCP, ReceivedSignalCodePower), also can be Reference Signal Received Quality (RSRQ, ReferenceSignalReceivingQuality).In this step, can treat that the RSRP that dispatch terminal measurement reports and the first pre-determined threshold compare by this, or treat the RSRP that dispatch terminal measurement reports and treat that the RSRP difference of other base stations that base station residing for dispatch terminal is adjacent compares with the second pre-determined threshold with this again to show that this treats whether dispatch terminal belongs to edge customer by this.
Preferably, in above-mentioned steps 201, can by treating that dispatch terminal channel quality parameter and preset channel deterioration thresholding compare, treat described in determining whether dispatch terminal is subject to the interference of adjacent macro station, if this treats that dispatch terminal channel quality parameter is less than or equal to preset channel deterioration thresholding, then show that this treats that dispatch terminal receives interference; Otherwise, then show that this treats that dispatch terminal is interference-free, following two kinds of optimal ways can be had specifically:
Mode one: by treating that the RSRP that dispatch terminal measurement reports and the first preset channel deterioration thresholding compare, such as the first preset channel deterioration thresholding is set to-90dBm, if this treats that the RSRP that dispatch terminal measurement reports is less than or equal to-90dBm, then this treats that dispatch terminal receives interference; Treat that the RSRP of macro station in the neighbor cell, micro-station that dispatch terminal reports is more than or equal to preset by grand interference threshold by this simultaneously, adjudicate this and treat whether dispatch terminal is subject to the interference of adjacent macro station.
Mode two: by treating that the SINR that dispatch terminal measurement reports and the second preset channel deterioration thresholding compare, such as the second preset channel deterioration thresholding is set to 3dB, if treat that the SINR that dispatch terminal measurement reports is less than or equal to 3dB, then this treats that dispatch terminal receives interference; Simultaneously by be disturbed treat that dispatch terminal reports neighbor cell, micro-station in the RSRP of macro station be more than or equal to preset and adjudicate this by grand interference threshold and treat whether dispatch terminal is subject to the interference of adjacent macro station.
Further, by above-mentioned judging process, can judge to treat that dispatch terminal belongs to edge customer or central user and whether disturbs by macro station, thus described in can determining, treat the type of dispatch terminal, wherein, one Terminal Type is the central user at micro-station, two Terminal Types be micro-station edge customer and by the interference of adjacent macro station, three Terminal Types be micro-station edge customer and not by the interference of adjacent macro station.
Treat described in being determined by step 201 that dispatch terminal is the edge customer at micro-station and after interference by adjacent macro station, needs to determine in step 202. the interference macro station set treating dispatch terminal described in disturbing.By the judging process of step 201, the cell ID of interference macro station can be known.If the adjacent macro station number meeting this condition is more than or equal to 1, then show that this treats that dispatch terminal is subject to the interference of 1 or multiple macro station, then record meets all macro station communities of this condition, determines the interference macro station set treating dispatch terminal described in disturbing.
In step 203, according to the almost blank subframe ABS pattern that each macro station in the interference macro station set received sends, treating the ABS subframe that dispatch terminal uses described in determining, can be specifically ABS subframe in macro station ABS pattern each in the set of described interference macro station is got common factor or union; According to the ABS subframe of getting after common factor or union, described in determining, treat the ABS subframe that dispatch terminal uses.Such as shown in Fig. 1, treat that dispatch terminal UE4 disturbs by macro station M1 and M2, then the interference macro station set of UE4 is { M1, M2}, be { frame 0 subframe 5, frame 1 subframe 0} as micro-station P2 receives the ABS subframe pattern that macro station M1 sends, receiving the ABS subframe pattern that macro station M2 sends is { frame 0 subframe 0, frame 1 subframe 0, frame 1 subframe 6}, then UE4 can be dispatched to the ABS subframe that M1 and M2 send and get common factor { frame 1 subframe 0}, or union { frame 0 subframe 0, frame 1 subframe 0, frame 1 subframe 6, frame 0 subframe 5}.To different, micro-station P2 treats that dispatch terminal can adopt the mode of different determination ABS subframes, as adopted ABS subframe to get the mode of common factor to UE4, UE5 being got to the mode of union, all not doing concrete restriction in this programme.
Preferably, after treating the ABS subframe that dispatch terminal uses described in determining in the embodiment of the present invention, the requirement of dispatch terminal to service rate is treated according to described, treat described in determining that dispatch terminal uses the priority of ABS subframe, ensure bit rate (GBR, GuaranteedBitRate) treat that the priority of dispatch terminal is higher than non-guaranteed bit rate (N-GBR, Non-GuaranteedBitRate) treat dispatch terminal, wherein, GBR treats that dispatch terminal is to the guaranteed rate requirement of business and to time delay, speed, the indexs such as Block Error Rate have high-level terminal, N-GBR treats that dispatch terminal is terminal service rate not being had to guaranteed rate requirement.
Preferably, for three Terminal Types determined in step 201, micro-standing in when dispatching subframe can adopt different strategies, thus ensures the utilance of scheduling subframe, and the interference that dispatch terminal is subject to is treated in reduction.Scheduling subframe comprises two kinds: one is ABS subframe, within the ABS sub-frame configuration cycle, be namely designated the subframe of almost blank subframe by all macro stations; Another is non-ABS subframe, namely at all descending sub frames in the ABS sub-frame configuration cycle except ABS subframe.

The scheduling subframe of one Terminal Type is non-ABS subframe and ABS subframe;
The scheduling subframe of two Terminal Types is non-ABS subframe and ABS subframe; When this two Terminal Type is dispatched to ABS subframe, only can be dispatched in ABS subframe that in interference macro station set corresponding to this two Terminal Type, all macro stations is distributed, and only have during resources left in the operation quality requirement and non-ABS subframe that do not meet this two Terminal Type and just allow to be dispatched in non-ABS subframe;
The scheduling subframe of three Terminal Types is non-ABS subframe.
Preferably, according to the described type treating dispatch terminal, treat described in determining that dispatch terminal is in the priority using ABS subframe and/or non-ABS subframe, wherein, one Terminal Type is as central user, and quality of service is better, is generally dispatched in ABS subframe when ABS sub-frame resources has residue by a Terminal Type, can not only effectively utilize macro station ABS sub-frame resources, and contribute to promoting user awareness further; Three Terminal Types are as the edge customer not by grand interference, scheduling subframe is non-ABS subframe, for improving this three Terminal Types quality of service and taking into account user fairness, promote user awareness, the dispatching priority of three Terminal Types on non-ABS is ranked the first, to sum up, the priority of ABS subframe is used to be followed successively by two Terminal Types, a Terminal Type from high to Low; The priority of non-ABS subframe is used to be followed successively by three Terminal Types, a Terminal Type and two Terminal Types from high to Low.
Preferably, the type treating dispatch terminal according to described and describedly treat the requirement of dispatch terminal to service rate, treats described in determining that dispatch terminal is in the priority using ABS subframe and/or non-ABS subframe;
Wherein, the priority using ABS subframe is two class GBR terminal > bis-class N-GBR terminal > mono-class GBR terminal > mono-class N-GBR terminals;
