The CSI feedback method comprises the following steps that: user equipment (UE) determines antenna port configuration of a base station; the UE determines a data transmission mode and a CSI feedback mode; the UE determines a feedback relevant parameter; and the UE reports the CSI according to the determined antenna port configuration of the base station, the determined data transmission mode, the determined feedback mode and the determined feedback relevant parameter. According to the invention, a feedback period and a feedback time scheme are provided for supporting feedback mode with four report types, so that completeness of a CSI feedback mode in a standard can be improved; moreover, system efficiency can be enhanced; and the system stability and the transmission performance can also be improved.
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 the system; If transmitter can be known channel information with certain mode, just can be optimized sending signal, thereby improve the quality of reception and reduce requirement the receiver complexity according to the characteristic of channel.The general mode feedback channel information that adopts quantized channel information in real system to reduce feedback overhead, improves system transmissions efficient.
Adopt implicit expression CSI (Channel State Information, channel condition information) feedback method in LTE (Long Term Evolution, the Long Term Evolution) system based on code book.In order to realize the periodic feedback of channel condition information, defined 4 kinds of dissimilar report contents altogether:
Class1 report: select CQI (indication of the Channel Quality Indication channel quality) feedback of subband in order to support UE (User Equipment, subscriber equipment);
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.
Still adopt implicit expression CSI feedback method in LTE-A (Long Term Evolution-Advanced, the long-term evolution upgrading) system based on code book.UE is based on the pilot measurement down channel, and the data fluxion RI value that reports down link to support to the base station according to himself reception Processing Algorithm) and the label PMI of pre-coding matrix, UE also need report the channel quality CQI of each code word simultaneously.Wherein, the RI/PMI of its recommendation has been used in UE hypothesis base station in the computational process of CQI.In order to improve the feedback accuracy of PMI, a pre-coding matrix (W) is formed by two matrixes (W1 and W2) merging in LTE-A, and W1 and W2 are respectively through two PMI (a PMI value is corresponding to W1 indication and the 2nd PMI value, corresponding to the W2 indication) indication.Wherein, 2 antenna ports and continue to use the code book in the LTE R8/9 version below 4 antenna ports are defined as unit matrix with W1, and a PMI value comprises 0 bit information and need not feedback.
In the LTE-A standard, with PUCCH 2-1 (PUCCH:Physical Uplink Control Channel, the Physical Uplink Control Channel) feedback model of introducing expansion.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 realized following function:
1, pre-coding matrix W confirms based on the RI report that reports recently and the report content of 3 sub-frame.
2, the form of 3 reports is respectively:
1) report 1:RI and PTI (precoder type indication, the indication of 1 bit precoding type);
2) report 2:
If PTI=0 then reports W1, also promptly, a PMI value;
If PTI=1 then reports broadband CQI and broadband W2, also be broadband the 2nd PMI value.
3) report 3:
If PTI=0 then reports broadband CQI and broadband W2, also be broadband the 2nd PMI value;
If PTI=1 then reports subband CQI and subband W2, also be subband the 2nd PMI value.
3, for 2 antenna ports and 4 antenna ports, then PTI be configured to all the time 1 and need not the indication.
The content of PTI determines by UE, through indicating different PTI, UE can determine to report 2 with the content of report 3.
Occur 4 types report in the above feedback model altogether, be respectively:
Type A report: in order to support subband CQI and subband W2 (also being subband the 2nd PMI value) feedback;
Type B report: in order to support broadband CQI and broadband W2 (also being broadband the 2nd PMI value) feedback;
Type C report: in order to support W1 (also being a PMI value) feedback;
Type D report: report in order to support RI and PTI.
More than 4 kinds of Report Types all be different from defined 4 types of Report Types among the LTE R8/9.
Owing under the PUCCH 2-1 pattern of expansion, multiple new Report Type occurred, and at present not clear and definite as yet with report cycle constantly for reporting of these Report Types, the definition to this channel condition information feedback model in the standard is also incomplete.To reporting constantly and report cycle of expansion PUCCH 2-1, present existing scheme is following.
