If it has, UE determines that the 7th bit gate is limited to the bit thresholding that cycle CSI information merges；
If it did not, UE determines that the 8th bit gate is limited to the bit thresholding that cycle CSI information merges.
In actual application, cycle CSI information is closed to select any of the above-described kind of mode to determine according to system actual demand
And bit thresholding.It should be pointed out that, cycle CSI information can also be determined according to other rules.As long as
It is that the cycle CSI information according to conflict selects one as this cycle from multiple preset bit thresholdings
CSI information merges the bit thresholding used, and each falls within protection scope of the present invention.
If use above-mentioned first or the second way determine the bit thresholding that cycle CSI information merges.That
, the specific implementation of step 110 may is that the UE reporting according to predetermined cycle CSI information

For example and without limitation, the reporting type priority rule of predetermined cycle CSI information is permissible
It is:
For the cycle CSI information that identical traffic point (or interference it is assumed that or carrier wave) is corresponding, reporting type
The priority of 3,5,6 is higher than reporting type1,1a, 2,2a, 2b, 2c, 4.

For clashing and disturb the cycle CSI information assuming that priority is identical, UE is according to predetermined week
The interference hypothesis priority rule that phase CSI information is corresponding, to the cycle CSI information sorting clashed, enters
One step includes:
According to the feedback kind priority rule of predetermined cycle CSI information, to clashing and corresponding interference
Assume the cycle CSI information sorting that priority is identical.
Or,
According to the carrier type priority rule that predetermined cycle CSI information is corresponding, to clashing and corresponding

Or,
Priority rule is assumed in the interference corresponding according to predetermined cycle CSI information, to clashing and corresponding
The cycle CSI information sorting that carrier wave priority is identical.
Below in conjunction with concrete application scenarios, the method providing the embodiment of the present invention describes in detail.
In first application scenarios, it is assumed that UE needs to feed back 3 different interference and assumes each self-corresponding
CSI(represents with CSI report1, CSI report2, CSI report3), the report cycle of each CSI by
Base station configures；UE according to configuration report cycle in PUCCH respectively according to respective reporting type
Report each cycle CSI information.
UE arranges with base station: when reporting type is identical, CSI report index value is the lowest, the cycle
The priority of CSI information is the highest；During reporting type difference, the priority of different reporting type
As follows:
The priority of the reporting types3,5,6 in identical CSI report is higher than reporting tpe1,1a,
2,2a,2b,2c,4。
The reporting types priority of different CSI report is as follows:
Limit priority: reporting type3,5,6,2a
Secondary high priority: reporting type2,2b, 2c, 4
Lowest priority: reporting type1,1a
Meanwhile, UE and base station agreement: if comprising RI in cycle CSI information, then cycle CSI information is closed
And bit gate be limited to 10 bits；Otherwise this bit gate is limited to 20 bits.
If reporting moment, UE to need simultaneously to report the RI(2 bit of CSI report1, reporting at certain
Type3), the broadband PMI/CQI(11 bit of CSI report2, reporting type2) and CSI report3
RI(2 bit, reporting type3).Then cycle CSI reports implementation as in figure 2 it is shown, concrete
Including operating as follows:
Step 200, UE determine in the cycle CSI information clashed and comprise RI information；
Step 210, UE determine and report the moment at this, and the bit gate that cycle CSI information merges is limited to 10 ratios
Special；
Step 220, UE are according to the priority rule arranged with base station, to the cycle CSI letter clashed
Breath sequence.
Concrete, according to above-mentioned agreement, the cycle CSI information sorting result of conflict is { CSI report1's
The broadband PMI/CQI} of the RI of RI, CSI report3, CSI report2.Its order is cycle CSI information
The descending of priority.
Step 230, in 10 bit range, UE is according to the priority descending of cycle CSI information of conflict
Select the RI of RI and the CSI report3 of CSI report1.
Step 240, UE give the correct time after being merged by the RI of RI and the CSI report3 of CSI report1 on this
The PUCCH carved reports.
According to the thresholding of 10 bits, UE can only report the first two RI information, it is impossible to reports CSI report2
Broadband PMI/CQI information, therefore in this reports the PUCCH in moment, the actual information reported is { CSI
The RI} of the RI of report1, CSI report3.
By above-mentioned processing procedure, when the cycle CSI information clashed comprises RI information, preferentially
Report RI information, and by selecting bit thresholding corresponding to RI information, it is ensured that the transmission of RI information
Performance.
In second application scenarios, it is assumed that UE needs to feed back 3 different interference and assumes each self-corresponding
CSI(represents with CSI report1, CSI report2, CSI report3), the report cycle of each CSI by
Base station configures；UE according to configuration report cycle in PUCCH respectively according to respective reporting type
Report each cycle CSI information.
UE arranges with base station: when reporting type is identical, CSI report index value is the lowest, the cycle
The priority of CSI information is the highest；During reporting type difference, the priority of different reporting type
As follows:
The priority of the reporting types3,5,6 in identical CSI report is higher than reporting type1,1a,
2,2a,2b,2c,4。
The reporting types priority of different CSI report is as follows:
Limit priority: reporting type3,5,6,2a
Secondary high priority: reporting type2,2b, 2c, 4
Lowest priority: reporting type1,1a
Meanwhile, UE and base station agreement: if it is the highest to comprise priority in the cycle CSI information of conflict
The CSI information of reporting type, then the bit gate that cycle CSI information merges is limited to 10 bits；If
The cycle CSI information of conflict does not comprise the cycle CSI information of the highest reporting type of priority, but
Comprise the cycle CSI information of the second highest reporting type of priority, the then bit that cycle CSI information merges
Thresholding is 15 bits；If the cycle CSI information of conflict only comprises the reporting type that priority is minimum
Cycle CSI information, then cycle CSI information merge bit gate be limited to 20 bits.
If in certain reports the moment, UE needs to report the arrowband CQI(12 ratio of CSI report1 simultaneously
Spy, reporting type1), the broadband PMI/CQI(8 bit of CSI report2, reporting type2)
With the broadband PMI/CQI(8 bit of CSI report3, reporting type2).Then cycle CSI reports reality
Existing mode is as it is shown on figure 3, specifically include following operation:
Step 300, UE determine that not comprise priority in the cycle CSI information clashed the highest
The cycle CSI information of reporting type, but comprise the cycle CSI of the second highest reporting type of priority
Information；
