Long Term Evolution strengthens (LTE-A, Long-Term Evolution-Advanced) system adopts identical networking, when increasing substantially the availability of frequency spectrum, also can make the subscriber equipment (UE of cell edge, User Equipment, also referred to as terminal) signal seriously declines, and is subject to the higher interference from other communities.If signal fadeout and interference problem are not processed, will have a strong impact on the data transmission performance of Cell Edge User equipment.Multipoint cooperative (CoMP, Coordinated Multiple Point) technology is by introducing information interaction and the joint transmission between many communities, not only can improve signal quality, also can reduce presence of intercell interference, thereby can increase substantially the data transmission performance of Cell Edge User equipment.
Current coordinated multipoint transmission scheme roughly can be divided into: dynamic transmission point selection (DPS, Dynamic Point Selection), cooperative beam figuration (CBF, Coordinated BeamForming), joint transmission (JT, or the hybrid plan of above 3 class transmission plans Joint Transmission).Such as, DPS and CBF combine, and main transfer point is determined by Dynamic Selection, and by combined dispatching, is realized cooperative beam figuration etc. between the cooperation transmission point outside main transfer point., also can not signal by allowing some transfer point vacate on some running time-frequency resource meanwhile, thereby reduce the interference to other transfer points, realize frequency domain interference flexibly and coordinate, this type of technology is called dynamic blank (DB, Dynamic Blanking).In real system, a transmission mode may comprise multiple transmission plan, supports that the pattern between all kinds of transmission plans is switched.In order to guarantee better transmission performance and the stability of a system, in the transmission mode of supporting CoMP to transmit, often need to support the switching to unicast.
System is by the different channel state information reference signals (CSI-RS of configuration, Channel State Information-Reference Signal) make subscriber equipment can measure the down channel of each transfer point, each transfer point is corresponding to a CSI-RS resource.It should be noted that transfer point can be the transfer point of a physics, and can be a virtual transfer point, each virtual transfer point consists of the transfer point of one or more physics.
Realize after down channel measurement, according to the needed channel condition information of transmission plan (CSI, Channel State Information), carry out information feedback.All kinds of transmission plans need corresponding channel condition information support.Such as, DPS transmission plan needs the channel condition information of a plurality of transfer points, or the channel condition information of some transfer points and the corresponding CSI-RS index information of this transfer point.DPS transmission plan in conjunction with DB technology needs the channel quality information under multiple interference supposed situation.A plurality of transfer points of JT transmission plan needs are fed back the channel condition information of identical order (Rank) etc.
In existing Long Term Evolution (LTE, Long-Term Evolution) system, support two class CSI feedback systems.That is, the feedback of the cycle CSI based on Physical Uplink Control Channel (PUCCH, Physical Uplink Control CHannel) and CSI feedback aperiodic based on Physical Uplink Shared Channel (PUSCH, Physical Uplink Shared CHannel).
Cycle CSI feedback based on PUCCH comprises 4 class feedback models (reporting mode): pattern 1-0, pattern 2-0, pattern 1-1 and pattern 2-1.Cycle CSI feedback packet based on PUCCH containing 1,1a, 2,2a, 2b, 2c, 3,4,5 and 6 totally 10 kinds of feedback kind (reporting type).Wherein pattern 1-1 and 2-1 support package are containing the CSI feedback of pre-coding matrix indication (PMI, Precoding Matrix Indicator), and pattern 1-0 and 2-0 support not comprise the CSI feedback of PMI feedback.

Wherein, Type2 is used for feeding back broadband (Wideband) PMI/ channel quality indication (CQI, Channel Quality Indicator) .Tpye3 and is used for feeding back order indication (RI, Rank Indicator).
For the configuration of 8 antenna ports, pattern 1-1 comprises 2 subpatterns, is respectively subpattern 1 and subpattern 2.
Pattern 1-1 subpattern 1, has 2 kinds of reporting type, that is, and and Type2b and Tpe5.Wherein, Type2b is used for feeding back CQI/ broadband, broadband the 2nd PMI, and Type5 is used for feeding back RI/ broadband the one PMI.

Pattern 2-1:
For the configuration of 2 or 4 antenna ports, there are 3 kinds of reporting type, that is, and Type1, Type2 and Type3.Wherein, Type1 is used for feeding back subband (Sub-band) CQI, and Type2 is used for feeding back broadband P MI/CQI, and Type3 is used for feeding back RI.
For the configuration of 8 antenna ports, according to the difference of precoding type indication (PTI, Precoder Type Indicator), reporting type is also different, concrete:
When PTI=0, there is Type2b, Type2a and Type6.Wherein, Type2b is used for feeding back CQI/ broadband, broadband the 2nd PMI, and Type2a is used for feeding back broadband the one PMI, and Type6 is used for feeding back RI/PTI;
When PTI=1, there is Type1a, Type2b and Type6.Wherein, Type1a is used for feeding back subband CQI/ subband the 2nd PMI, and Type2b is used for feeding back CQI/ broadband, broadband the 2nd PMI Type6 for feeding back RI/PTI;

Wherein, a plurality of cycle CSI information same report constantly to merge to report refer to, the PUCCH of a plurality of cycle CSI information in same subframe merges and reports.
Below in conjunction with accompanying drawing, the embodiment of the present invention is elaborated.
If there are at least two cycle CSI informational needs constantly to report same reporting, at least two cycle CSI information clash same reporting constantly, a kind of cycle CSI report method that embodiment of the present invention provides, its implementation as shown in Figure 1, specifically comprises following operation:
Step 100, UE, according to the above-mentioned cycle CSI information clashing, determine the bit thresholding that cycle CSI information merges.
Step 110, UE are according to predetermined priority rule, to the cycle CSI information sorting clashing.
In the scope of step 120, the bit thresholding that merges in above-mentioned cycle CSI information, UE selects at least one cycle CSI information according to the priority descending of the cycle CSI information clashing from the above-mentioned cycle CSI information clashing.
Concrete, UE is according to the priority descending of the cycle CSI information clashing, maximum cycle CSI information in the bit threshold range that selection cycle CSI information merges from the above-mentioned cycle CSI information clashing.
For example, according to priority descending, total size of top n cycle CSI information surpasses the bit thresholding that cycle CSI information merges, N-1 cycle CSI information before selecting.
Step 130, UE report the cycle CSI information of selection in above-mentioned reporting constantly.
Wherein, if the cycle CSI information of selecting surpasses one, UE reports in above-mentioned reporting after the cycle CSI information of selection is merged according to priority descending constantly.The length of the cycle CSI information after merging is not more than the bit thresholding that cycle CSI information merges.

UE, according to Serving cell corresponding to cycle CSI information clashing, determines the bit thresholding that cycle CSI information merges.Particularly:
Cycle CSI information corresponding to Serving cell that whether has this UE in the CSI information of UE judgement conflict;
If had, UE determines that the 5th bit gate is limited to the bit thresholding that cycle CSI information merges;
If no, UE determines that the 6th bit gate is limited to the bit thresholding that cycle CSI information merges.
Five, UE side presets the 7th bit thresholding and the 8th bit thresholding, and presets corresponding bit thresholding and really establish rules as follows: if there is the cycle CSI information that main carrier is corresponding in the cycle CSI information clashing, and corresponding the 7th bit thresholding.If there is no the cycle CSI information that main carrier is corresponding in the cycle CSI information of conflict, corresponding the 8th bit thresholding.Wherein, the 7th bit thresholding is less than the 8th bit thresholding, and the value of the 7th bit thresholding and the 8th bit thresholding can be set according to system actual demand, and the present invention is not construed as limiting.For example and without limitation, can the value of the 7th bit thresholding be set according to the transmission performance demand of cycle CSI information corresponding to main carrier, the maximum number bits that can carry according to PUCCH is determined the 8th bit thresholding.
UE determines according to carrier wave corresponding to cycle CSI information clashing the bit thresholding that cycle CSI information merges.Particularly:
In the CSI information of UE judgement conflict, whether there is the cycle CSI information that main carrier is corresponding;
If had, UE determines that the 7th bit gate is limited to the bit thresholding that cycle CSI information merges;
If no, UE determines that the 8th bit gate is limited to the bit thresholding that cycle CSI information merges.
In practical application, according to system actual demand, select above-mentioned any mode to determine the bit thresholding that cycle CSI information merges.It should be pointed out that also and can determine cycle CSI information according to other rules.So long as select one to merge the bit thresholding using as this cycle CSI information according to the cycle CSI information of conflict, all fall into protection scope of the present invention from a plurality of preset bit thresholdings.

Below in conjunction with concrete application scenarios, the method that the embodiment of the present invention is provided describes in detail.
In first application scenarios, suppose that UE need to feed back 3 different interference and suppose that each self-corresponding CSI(is with CSI report1, CSI report2, CSI report3 represents), the report cycle of each CSI is configured by base station; UE reports each cycle CSI information according to reporting type separately according to the report cycle of configuration respectively in PUCCH.
UE arranges with base station: when reporting type is identical, CSI report index value is lower, and the priority of cycle CSI information is higher; When reporting type is different, the priority of different reporting type is as follows:
Reporting types3 in identical CSI report, 5,6 priority is higher than reporting tpe1,1a, 2,2a, 2b, 2c, 4.
The reporting types priority of different CSI report is as follows from high to low:
Limit priority: reporting type3,5,6,2a
Inferior high priority: reporting type2,2b, 2c, 4
Lowest priority: reporting type1,1a
Meanwhile, UE and base station agreement: if comprise RI in cycle CSI information, the bit gate that cycle CSI information merges is limited to 10 bits; Otherwise this bit gate is limited to 20 bits.
If reported constantly at certain, UE need to report the RI(2 bit of CSI report1, reporting type3 simultaneously), the broadband P MI/CQI(11 bit of CSI report2, reporting type2) and the RI(2 bit of CSI report3, reporting type3).Cycle CSI reports implementation as shown in Figure 2, specifically comprises following operation:
In step 200, the definite cycle CSI information clashing of UE, comprise RI information;
Step 210, UE determine at this and report constantly, and the bit gate that cycle CSI information merges is limited to 10 bits;
Step 220, UE are according to the priority rule with base station agreement, to the cycle CSI information sorting clashing.
Concrete, according to above-mentioned agreement, the cycle CSI information sorting result of conflict is { RI of CSI report1, the RI of CSI report3, the broadband P MI/CQI} of CSI report2.It is sequentially the descending of the priority of cycle CSI information.
Step 230, in 10 bit range, UE selects the RI of CSI report1 and the RI of CSI report3 according to the priority descending of the cycle CSI information of conflict.
Step 240, UE report in PUCCH constantly and report at this after the RI of the RI of CSI report1 and CSI report3 is merged.
According to the thresholding of 10 bits, UE can only report the first two RI information, can not report the broadband P MI/CQI information of CSI report2, and therefore at this, reporting the actual information reporting in PUCCH is constantly { RI of CSI report1, the RI} of CSI report3.
By above-mentioned processing procedure, while comprising RI information in the cycle CSI information clashing, preferentially report RI information, and by selecting bit thresholding corresponding to RI information, guaranteed the transmission performance of RI information.
In second application scenarios, suppose that UE need to feed back 3 different interference and suppose that each self-corresponding CSI(is with CSI report1, CSI report2, CSI report3 represents), the report cycle of each CSI is configured by base station; UE reports each cycle CSI information according to reporting type separately according to the report cycle of configuration respectively in PUCCH.
UE arranges with base station: when reporting type is identical, CSI report index value is lower, and the priority of cycle CSI information is higher; When reporting type is different, the priority of different reporting type is as follows:
Reporting types3 in identical CSI report, 5,6 priority is higher than reporting type1,1a, 2,2a, 2b, 2c, 4.
The reporting types priority of different CSI report is as follows from high to low:
Limit priority: reporting type3,5,6,2a
Inferior high priority: reporting type2,2b, 2c, 4
Lowest priority: reporting type1,1a
Meanwhile, UE and base station agreement: if the CSI information that comprises the reporting type that priority is the highest in the cycle CSI information of conflict, the bit gate that cycle CSI information merges is limited to 10 bits; If do not comprise the cycle CSI information of the reporting type that priority is the highest in the cycle CSI information of conflict, but the cycle CSI information that comprises the inferior high reporting type of priority, the bit gate that cycle CSI information merges is limited to 15 bits; If only comprise the cycle CSI information of the reporting type that priority is minimum in the cycle CSI information of conflict, the bit gate that cycle CSI information merges is limited to 20 bits.
If in certain reports constantly, UE need to report the arrowband CQI(12 bit of CSI report1 simultaneously, reporting type1), the broadband P MI/CQI(8 bit of CSI report2, reporting type2) and the broadband P MI/CQI(8 bit of CSI report3, reporting type2).Cycle CSI reports implementation as shown in Figure 3, specifically comprises following operation:
In step 300, the definite cycle CSI information clashing of UE, do not comprise the cycle CSI information of the reporting type that priority is the highest, but the cycle CSI information that comprises the inferior high reporting type of priority;
Step 310, UE determine that this reports constantly, and the bit gate that cycle CSI information merges is limited to 15 bits.
Step 320, UE are according to the priority rule with base station agreement, to the cycle CSI information sorting clashing.
Concrete, according to above-mentioned agreement, the cycle CSI information sorting result of conflict is { the broadband P MI/CQI of CSI report2, the broadband P MI/CQI of CSI report3, the arrowband CQI} of CSI report1.It is sequentially the descending of the priority of cycle CSI information.
Step 330, in 15 bit range, UE selects the broadband P MI/CQI of CSI report2 according to the priority descending of the cycle CSI information of conflict.
Step 340, UE report the broadband P MI/CQI of CSI report2 in PUCCH constantly and report at this.
According to the thresholding of 15 bits, UE can only report the broadband P MI/CQI information of CSI report2, can not report two information that priority is lower, and therefore at this, reporting the actual information reporting in PUCCH is constantly { the broadband P MI/CQI} of CSI report2.
By above-mentioned processing procedure, can guarantee reporting of cycle CSI information that reporting type priority is higher, and can meet the transmission performance demand of the cycle CSI information reporting.
In the 3rd application scenarios, suppose that UE need to feed back each self-corresponding CSI(of 3 different transfer points with CSI report1, CSI report2, CSI report3 represents), the report cycle of each CSI is configured by base station; UE reports each cycle CSI information according to reporting type separately according to the report cycle of configuration respectively in PUCCH.
The priority of different transfer points has been arranged in UE and base station, and the priority of higher its corresponding cycle CSI information of transfer point of priority of agreement level is higher.Suppose priorities is CSI report1>CSI report2>CSI report3, and the transfer point that wherein CSI report1 is corresponding is main transfer point.
Meanwhile, UE and base station agreement: if the feedback information that comprises main transfer point in the cycle CSI information of conflict, the bit gate that cycle CSI information merges is limited to 15 bits; Otherwise this bit gate is limited to 20 bits.
If in certain reports constantly, UE need to report the RI(2 bit of CSI report1 simultaneously, reporting type3), the broadband P MI/CQI(11 bit of CSI report2, reporting type2) and the RI(2 bit of CSI report3, reporting type3), cycle CSI reports implementation as shown in Figure 4, specifically comprises following operation:
In step 400, the definite cycle CSI information clashing of UE, comprise cycle CSI information corresponding to main transfer point;
Step 410, UE determine and report constantly, and the bit gate that cycle CSI information merges is limited to 15 bits.
Step 420, UE are according to the priority rule with base station agreement, to the cycle CSI information sorting clashing.
Concrete, according to above-mentioned agreement, the cycle CSI information sorting result of conflict is { RI of CSI report1, the PMI/CQI of CSI report2, the broadband RI} of CSI report3.It is sequentially the descending of the priority of cycle CSI information.
Step 430, in 15 bit range, UE selects the RI of CSI report1 and the PMI/CQI of CSI report2 according to the priority descending of the cycle CSI information of conflict.
Step 440, UE report in PUCCH constantly and report at this after the PMI/CQI of the RI of CSI report1 and CSI report2 is merged.
According to the thresholding of 15 bits, UE can only report the first two CSI information that priority is the highest, can not report last information, and therefore at this, reporting the actual information reporting in PUCCH is constantly { RI of CSIreport1, the PMI/CQI} of CSI report2.
By above-mentioned processing procedure, UE and base station are arranged main transfer point and are had limit priority, thereby guarantee reporting of cycle CSI information that main transfer point is corresponding, and can meet the transmission performance demand of CSI information corresponding to main transfer point.
In the 4th application scenarios, suppose that UE need to feed back each self-corresponding CSI(of 3 different carriers with CSI report1, CSI report2, CSI report3 represents), the report cycle of each CSI is configured by base station; UE reports each cycle CSI information according to reporting type separately according to the report cycle of configuration respectively in PUCCH.
The priority of different carrier has been arranged in UE and base station, and the priority of higher its corresponding cycle CSI information of carrier wave of priority of agreement level is higher.Suppose priorities is CSI report1>CSI report2>CSIreport3, and the carrier wave that wherein CSI report1 is corresponding is main carrier.
Meanwhile, UE and base station agreement: if the feedback information that comprises main carrier in the cycle CSI information of conflict, the bit gate that cycle CSI information merges is limited to 15 bits; Otherwise this bit gate is limited to 20 bits.
If in certain reports constantly, UE need to report the RI(2 bit of CSI report1 simultaneously, reporting type3), the broadband P MI/CQI(11 bit of CSI report2, reporting type2) and the RI(2 bit of CSI report3, reporting type3), cycle CSI reports implementation as shown in Figure 5, specifically comprises following operation:
In step 500, the definite cycle CSI information clashing of UE, comprise the cycle CSI information that main carrier is corresponding;
Step 510, UE determine and report constantly, and the bit gate that cycle CSI information merges is limited to 15 bits.
Step 520, UE are according to the priority rule with base station agreement, to the cycle CSI information sorting clashing.
Concrete, according to above-mentioned agreement, the cycle CSI information sorting result of conflict is { RI of CSI report1, the PMI/CQI of CSI report2, the broadband RI} of CSI report3.
Step 530, in 15 bit range, UE selects the RI of CSI report1 according to the priority descending of the cycle CSI information of conflict.
Step 540, UE report the RI of CSI report1 in PUCCH constantly and report at this.
According to the thresholding of 15 bits, UE can only report first CSI information that priority is the highest, can not report two CSI information next, and therefore at this, reporting the actual information reporting in PUCCH is constantly { the RI} of CSI report1.
By above-mentioned processing procedure, UE and base station agreement main carrier has limit priority, thereby guarantees reporting of cycle CSI information that main carrier is corresponding, and can meet the transmission performance demand of the CSI information that main carrier is corresponding.
