Description
Technical field
The present invention relates to wireless communication technology, particularly a kind of feedback of channel condition information and acquisition methods, equipment.
Background technology
MIMO (Multiple-Input Multiple-Output, multiple-input and multiple-output) in system, if transmitter can be known channel information in some way, just can to transmitted signal, be optimized according to the characteristic of channel, thereby improve the quality of reception and reduce the requirement to Receiver Complexity.The general mode feedback channel information that adopts quantized channel information in real system, to reduce feedback overhead, improves system efficiency of transmission.
In LTE (Long Term Evolution, Long Term Evolution) system, adopt implicit expression CSI (Channel State Information, the channel condition information) feedback method based on code book.In order to realize the periodic feedback of channel condition information, defined altogether 4 kinds of dissimilar report contents:
Class1 report: in order to support UE (User Equipment, subscriber equipment) to select CQI (indication of the Channel Quality Indication channel quality) feedback of subband;
Type 2 reports: in order to support broadband CQI and broadband P MI (Precooding Matrix Indicator, pre-coding matrix indication) feedback;
Type 3 reports: in order to support RI (Rank Indication, order indication) feedback;
Type 4 reports: in order to support broadband CQI feedback.
In LTE-A (Long Term Evolution-Advanced, long-term evolution upgrading) system, still adopt the implicit expression CSI feedback method based on code book.UE is based on pilot measurement down channel, and the data fluxion RI value that reports down link to support to base station according to the reception & disposal algorithm of himself) and the label PMI of pre-coding matrix, UE also needs to report the channel quality CQI of each code word simultaneously.Wherein, in the computational process of CQI, the RI/PMI of its recommendation has been used in UE hypothesis base station.In order to improve the feedback accuracy of PMI, in LTE-A, a pre-coding matrix (W) is merged and is formed by two matrixes (W1 and W2), W1 and W2 are respectively by two PMI (a PMI value, corresponding to W1 indication and the 2nd PMI value, corresponding to W2 indication) indication.Wherein, 2 antenna ports and 4 antenna ports are continued to use the code book in LTE R8/9 version below, W1 is defined as to unit matrix, and a PMI value comprise 0 bit information without feedback.
In LTE-A standard, PUCCH 2-1 (PUCCH:Physical Uplink Control Channel, the Physical Uplink Control Channel) feedback model of expansion will be introduced.In order to realize the periodic feedback of broadband P MI, broadband CQI and/or subband PMI, subband CQI.The PUCCH 2-1 feedback model of expansion will be achieved as follows function:
1, the report content of the RI of pre-coding matrix W based on reporting recently report and 3 subframes is determined.
2, the form of 3 reports is respectively:
1) report 1:RI and PTI (precoder type indication, 1 bit precoding type indication);
2) report 2:
If PTI=0, reports W1, also, a PMI value;
If PTI=1, reports CQIHe broadband, broadband W2, it is also broadband the 2nd PMI value.
3) report 3:
If PTI=0, reports CQIHe broadband, broadband W2, it is also broadband the 2nd PMI value;
If PTI=1, reports subband CQI and subband W2, it is also subband the 2nd PMI value.
3,, for 2 antenna ports and 4 antenna ports, PTI is configured to 1 and without indication all the time.
The content of PTI determines by UE, and by indicating different PTI, UE can determine to report 2 and the content of report 3.
In above feedback model, there is altogether the report of 4 types, be respectively:
Type A report: in order to support subband CQI and subband W2 (being also subband the 2nd PMI value) feedback;
Type B report: in order to support CQIHe broadband, broadband W2 (being also broadband the 2nd PMI value) feedback;
Type C report: in order to support W1 (being also a PMI value) feedback;
Type D report: in order to support RI and PTI to report.
Above 4 kinds of Report Types are all different from defined 4 class Report Types in LTE R8/9.
Under the PUCCH 2-1 pattern in expansion, there is multiple new Report Type, and at present for these Report Types report constantly and report cycle not yet clear and definite, also incomplete to the definition of this information feedback pattern in standard.For reporting constantly and report cycle of expansion PUCCH 2-1, current existing scheme is as follows.

The deficiencies in the prior art are:
At present, LTE/LTE-A also, not to supporting the feedback cycle of the feedback model of four kinds of Report Types constantly to stipulate with reporting, affects the completeness of such information feedback pattern in standard.
In addition, concerning concrete prior art scheme, even in existing such scheme 1 and scheme 2, not reporting types A report in the situation that of PTI=0, it is subband CQI and subband the 2nd PMI value, if PTI is long-term or be always 0, sub-band channel state information cannot be known in base station, thereby affects system effectiveness; In such scheme 2, type D report (being RI and PTI) report subframe relevant with PTI value, if last PTI value is fed back, make a mistake, be difficult to receive follow-up report, affect the stability of system.
