Description
Technical field
The present invention relates to the communications field, especially relate to the sending method of periodic channel state information in a kind of LTE (Long Term Evolution, Long Term Evolution) system.
Background technology
In the down link of LTE system; The base station is with certain hour interval pilot signal transmitted, and UE (user equipment, subscriber equipment) then measures the information of down channel according to this pilot signal; Comprise CQI (Channel Quality Indicator; CQI)/PMI (Pre-coding Matrix Indicator, pre-coding matrix indication) and RI (Rank Indicator, order indication).Then to these downlink channel condition informations of base station feedback.Base station dispatcher is according to this downlink channel condition information of UE feedback; Carry out scheduling of resource (resource scheduling) and adaptive modulation and coding (adaptive modulation and coding; AMC); Thereby on the basis that guarantees certain downlink transfer reliability, with the validity maximization of downlink transfer.
The modulation system of descending transmission is selected according to the CQI in the downlink channel condition information in the base station, if CQI is bigger, high order modulation can be selected in the base station so, improves the validity of transfer of data; PMI according in the downlink channel condition information selects pre-coding matrix, can reduce UE side complexity of decoding; Confirm the suitable transmission number of plies according to the RI in the downlink channel condition information, i.e. independent subchannels number, thus can carry out optimal utilization to channel characteristics, improve transmission rate.
UE can come to the base station feedback downlink channel condition information through aperiodic and cycle dual mode.Periodic feedback is fed back with aperiodic and is used different physical channels respectively.In LTE, uplink physical channel comprises: the ascending physical signal shared channel (Physical Uplink Control Channel, PUCCH), the ascending physical signal control channel (Physical Uplink Shared Channel, PUSCH) and Physical Random Access Channel.
For mode aperiodic, downlink channel condition information feeds back on PUSCH.The downlink channel condition information of UE feedback measurement is indicated through channel quality indication request (CQI Request) territory in the descending control information format 0 (DCI format 0) is put 1 in the base station.
For periodic mode, when not having upstream data to send, periodically downlink channel condition information sends on PUCCH.LTE system definition multiple PUCCH form (format), comprise PUCCH format1/1a/1b and format 2/2a/2b, wherein format 2/2a/2b is used to the downlink channel condition information in the cycle of sending.Below be that example specifies with CQI/PMI, provided the feedback model that CQI/PMI supported in cycle like table 1, and the employed feedback model of user side (UE, User Equipment) is by the semi-static configuration of high level; When existing upstream data has the down channel feedback information again, then upstream data and periodicity downlink channel condition information are sent on PUSCH.
Table 1:
Disturb in order to eliminate between the subchannel that causes owing to multipath transmisstion simultaneously; With the part of the regulation at the rear portion of sending data as protection (Guard Interval at interval; GI) be attached to the beginning of data division; This protection also is called Cyclic Prefix at interval, and (Cyclic Prefix CP), comprises regular circulation prefix (Normal CP) and extended cyclic prefix (Extended CP).In the cycle transmission, the base station is UE configuration cycle property report cycle and sub-frame offset through RRC (Radio Resource Control, Radio Resource control) signaling, and UE is in the moment of appointment feedback of down channel state information.
For broadband periodicity CQI/PMI, the transmission subframe of CQI/PMI is confirmed by following formula:
Wherein, N
OFFSET, CQIRefer to the transmission skew of CQI, N
PRefer to that CQI sends cycle, n
fRefer to System Frame Number, n
sRefer to timeslot number.
The transmission subframe of RI is confirmed by following formula:
Wherein, N
OFFSET, RIRefer to the transmission skew of RI, with respect to the number of subframes that CQI shifts to an earlier date, M
RIBe used to characterize RI and send the cycle, both value condition are as shown in table 2.
Table 2:
The existing protocol regulation when the transmission subframe of CQI/PMI that calculates through formula and RI is conflicted, can abandon CQI/PMI, only sends RI.N in the analytical table 2
OFFSET, RIAnd M
RIValue can know, have so a kind of special circumstances: work as I
RI=0 o'clock, N
OFFSET, RI=0, M
RI=1, the formula that calculates RI transmission subframe is in full accord with the formula that calculates CQI/PMI transmission subframe, and the transmission subframe of RI and CQI/PMI always clashes, and CQI/PMI is dropped.Obviously, in this case, if some special scheduling strategies are not taked in the base station; Can't obtain CQI/PMI information; When causing base station selected order of modulation and pre-coding matrix, lack important basis, the reliability of downlink transfer and validity can't guarantee; The reliability of UE side decoding can reduce, thereby reduces the descending performance of whole LTE system.If lean on the base station scheduling strategy to solve this problem, certainly will let the base station carry out frequent DCI0 scheduling, thereby increase the expense of downlink signaling.

Can find out that from table 4 (20, A) the original bit number of chnnel coding is at most 13bit.Periodically the CQI/PMI of downlink channel condition information is at most 11bit, and RI is at most 2bit, the maximum 2bit of ACK/NACK.Existing protocol regulation when RI and CQI/PMI clash, abandons CQI/PMI.
Table 4:
Yet, for Normal CP, no matter whether there is ACK/NACK; When CQI/PMI in the periodic channel state information or RI send on PUCCH, through (20, A) the original bit number before the chnnel coding is at most 11; (20, A) chnnel coding still has 2 original bit to utilize, and RI is at most 2 bits; Therefore when CQI/PMI and RI clash, can consider fully to let RI and CQI/PMI send simultaneously.
For Extended CP, because the reference symbol number is little, in order to improve the reliability of ACK/NACK decoding, need carry out RI in ACK/NACK and the periodic channel state information and/or CQI/PMI (20, A) channel combined coding.RI or CQI/PMI and ACK/NACK through (20, A) during coding, under the situation of no ACK/NACK, when RI and CQI/PMI clash, can let RI and CQI/PMI utilization (20, A) the associating transmission of encoding.Having under the situation of ACK/NACK, when RI and CQI/PMI clash, can find out from table 3; CQI/PMI only in the broadband, 4 transmitting antennas, and under the situation of RI＞1; Total bit number of RI and CQI/PMI is greater than 11, can't utilize this moment (20, A) RI, CQI/PMI and ACK/NACK are carried out combined coding; So, abandon CQI/PMI.Under other situation, total bit number of RI and CQI/PMI is at most 11, and (20, A) coding still has 2 original bit to utilize, therefore can be with RI, CQI/PMI and ACK/NACK combined coding.
Combine accompanying drawing that the present invention is done further explain through embodiment below.
The present invention provides a kind of sending method of periodic channel state information, may further comprise the steps:
1.1) when periodic channel state information is sent on PUCCH, RI, CQI/PMI are carried out (20, A) on PUCCH, send behind the channel combined coding;
1.2) when situation that CQI/PMI and RI clash,, CQI/PMI and RI are carried out (20 if be Normal CP; A) channel combined coding; Obtain first combined coding,, and ACK/NACK is attached on PUCCH, sends after first combined coding if there is ACK/NACK;
When CQI/PMI and RI clash, because CQI/PMI and maximum 13 bits of the total bit number of RI, and (20; A) the original coding input bit of channel is 13 bits, therefore, can make full use of (20; A) channel is encoded The combined, and need not adopt the mode that abandons CQI/PMI in the existing protocol.
1.3) if be Extent CP, CQI/PMI and RI and ACK/NACK are carried out (20, A) on PUCCH, send behind the channel combined coding.
If be Extended CP, because reference symbol is less, for the success rate that guarantees that ACK/NACK sends, therefore must ACK/NACK be carried out also (20, A) coding.And have only when feedback content be broadband CQI/PMI, feedback model is 4 transmitting antennas, and RI＞1; The Report mode Mode1-1 of PUCCH is under the situation of 11bits/BP, and total bit number of RI and CQI/PMI is just greater than 11 bits in the periodic channel state information, and total bit number of RI, CQI/PMI and ACK/NACK three is greater than (20 at this moment; A) channel original coding input bit number; Therefore abandon CQI/PMI, only RI and ACK/NACK are united and carry out that (20, A) coding then sends on PUCCH.
Other most situation; Total bit number of RI and CQI/PMI is not more than 11 bits in the periodic channel state information, and the original bit of ACK/NACK also is at most 2 bits, at this moment; Total bit number of three satisfies smaller or equal to (20; A) channel original coding input bit number, therefore with ACK/NACK with periodic channel state information RI, CQI/PMI carry out (20, A) on PUCCH, send behind the combined coding.
With respect to prior art, this execution mode has guaranteed the reliability of ACK/NACK decoding, has also guaranteed in most of scenes; When CQI/PMI and RI clashed, the base station can obtain CQI/PMI, thereby when base station selected order of modulation and pre-coding matrix; Important basis is provided; Guarantee the reliability and the validity of downlink transfer, improved the reliability of UE side decoding, thereby promoted the descending performance of whole LTE system.Simultaneously, made full use of that (20, A) channel resource is encoded.
2.1) when periodic channel state information is sent on PUSCH, with CQI/PMI and RI is multiplexing on said ascending physical signal shared channel, sends.
2.2) if there is ACK/NACK, then ACK/NACK, RI are sent on PUSCH with CQI/PMI is multiplexing.
With respect to prior art, this execution mode has been avoided when CQI/PMI and RI clash, and the base station abandons CQI/PMI, thereby has guaranteed that the base station can in time obtain CQI/PMI, during for base station selected order of modulation and pre-coding matrix, provides important basis.
The present invention has adopted the send mode of two kinds of periodic channel state information; The one, on PUCCH, send periodic channel state information, and when the CQI/PMI in the periodic channel state information and RI clash, do not abandon CQI/PMI; But make full use of (20; A) resource of chnnel coding, RI and/or CQI/PMI are carried out (20, A) channel combined coding transmission; The 2nd, on PUSCH, send periodically downlink channel condition information and upstream data, when the RI in the periodic channel state information and CQI/PMI clash, do not abandon CQI/PMI, RI and CQI/PMI are multiplexed on the PUSCH simultaneously send.With respect to existing protocol, when the RI in the periodic channel state information and CQI/PMI clash, abandon the mode of CQI/PMI; The present invention makes full use of the existing channel coding resource, does not abandon the mode of CQI/PMI, guarantees in most of scenes; The base station can in time obtain downlink channel condition information, comprises RI, CQI/PMI, thereby when base station selected order of modulation and pre-coding matrix; Important basis is provided, solves former protocols having under customized configuration, the problem that extra scheduling just can be obtained CQI/PMI need be carried out in the base station; Thereby save descending DCI0 expense, improve the validity and the reliability of downlink data transmission.
Please refer to Fig. 2; The present invention also provides a kind of system that sends periodic status information; Comprise: first coding module and second coding module and first sending module and second sending module, this first coding module links to each other with first sending module, and second coding module links to each other with second sending module.
First coding module and the second coding module said periodic channel state information that is used to encode wherein; Said first sending module is used to send the periodic channel state information after said first coding module is encoded, and said second sending module is used to send the periodic channel state information after said second coding module is encoded.And this first coding module comprises confirms subframe judging unit, prefix recognition unit and combined coding unit, and this confirms that subframe judging unit, prefix recognition unit link to each other with the combined coding unit successively.This affirmation subframe unit is used to judge whether to exist ACK/NACK; Whether the subframe that this prefix recognition unit is used to discern transmission is Normal CP; This combined coding unit be used for when said prefix recognition unit judged result when being, RI and CQI/PMI are carried out (20, A) channel combined coding obtains the first combined coding bit, again ACK/NACK is connected on the said first combined coding bit after; When this prefix recognition unit judged result for not the time, this combined coding unit is used for ACK/NACK, RI and ACK/NACK are carried out that (20, A) channel combined coding obtains the second combined coding bit.Wherein second coding module comprises the multiplexing and encoding unit and confirms the subframe judging unit, and this confirms that the subframe judging unit links to each other with the multiplexing and encoding unit; This affirmation subframe unit is used to judge whether to exist the ACK/NACK subframe; This multiplexing and encoding unit be used for when this affirmation subframe judgment unit judges result when being, with ACK/NACK, RI with the CQI/PMI multiplexing and encoding.
To combine specific embodiment and Fig. 1 that the present invention is done further explain below.
1, all transmission flows all come into force based on the configuration (or reprovision) of UE.
2, judge whether this subframe has PUSCH (DCI0=1), and cqirequest=1, be then to send the aperiodicity channel condition information by second sending module; Otherwise get into step 3.
3, judge this subframe whether periodically CQI/PMI and RI send subframe, be, then get into step 4 otherwise, no matter this channel condition information is cycle or aperiodic, does not send.
4, judging whether this subframe exists PUSC (DCI0=1), is then to get into step 5; Otherwise get into step 6.
5, whether this subframe of affirmation subframe judgment unit judges of second coding module exists ACK/NACK; Be that then the multiplexing and encoding unit of second coding module after periodic channel state information is multiplexing, sends by second sending module ACK/NACK on PUSCH; Otherwise; Directly,, do not abandon CQI/PMI even CQI/PMI and RI in this periodic channel state information clash with this periodic channel state information multiplexing transmission on PUSCH yet.
6, whether this subframe of affirmation subframe judgment unit judges of first coding module exists ACK/NACK, is then to get into step 7; Otherwise the combined coding unit RI in the periodic channel state information and CQI/PMI are carried out (20, A) on PUCCH, adopt format2 to send by first sending module behind the channel combined coding, even RI and CQI/PMI clash, do not abandon CQI/PMI yet.
Because when the RI in the periodic channel state information and CQI/PMI clash, suppose that the RI original bit is:
a
j(j＝0，1，...，A-1)，
Wherein A is a RI original bit number, A≤2 bits;
The CQI/PMI original bit is: b
i(i=0,1 ..., B-1),
Wherein B is a CQI/PMI original bit number, B≤11 bits;
Therefore total bit number smaller or equal to (20, A) several 13 bits of the original coding input bit of chnnel coding, then can CQI/PMI and the RI of periodic channel state information be carried out (20, A) channel combined coding, then (20, A) coding is imported original bit and is: s
i=b
i(i=0,1 ..., B-1), s
B+j=a
j(j=0,1 ..., A-1), promptly total bit is A+B≤13 bits.
7, the prefix recognition unit judges whether the CP into Normal; Be; The combined coding unit carries out (20 with periodic channel state information RI and CQI/PMI; A) channel combined coding appends to the ACK/NACK original bit after the coded-bit then, on PUCCH, adopts format2a or format2b to send by first sending module again.Even both send subframe and clash, can not abandon CQI/PMI yet; Otherwise, get into step 8.
Because of when the RI in the periodic channel state information and CQI/PMI clash, (20, A) the original input bit of chnnel coding: s
i=b
i(i=0,1 ..., B-1), s
B+j=a
j(j=0,1 ..., A-1), suppose that coded bit is c
k=(k=0,1 ..., C-1), C=20 wherein, the ACK/NACK original bit is: d
l=(l=0,1 ... D), wherein D is an ACK/NACK original bit number, D≤2 bits, and then final transmission bit is:
t
k=c
k(k=0,1 ..., C-1), t
C+l=d
l, C=20 bit wherein.
8, the sub-frame size judgment sub-unit judge periodic channel state information RI and CQI/PMI total bit number whether greater than 11; Be; Then when the RI in the periodic channel state information and CQI/PMI conflict, the subelement of then encoding abandons CQI/PMI, only RI and ACK/NACK is united and carries out (20; A) chnnel coding adopts format2 to send on PUCCH by first sending module again; Otherwise get into step 9.
9, the coding subelement periodic channel state information and ACK/NACK united carry out (20, A) encode, on PUCCH, adopt format2 to send by first sending module again.Even RI and CQI/PMI in the periodic channel state information clash, do not abandon CQI/PMI yet.
Because for (20; A) original bit 13 bits of chnnel coding input, total bit number of cycle channel information RI and CQI/PMI is smaller or equal to 11 bits, and the bit number of ACK/NACK is at most 2 bits; Total bit number of three satisfies smaller or equal to 13 bits; Therefore, can the three be carried out (20, A) channel combined coding.When RI and CQI/PMI clash, (20, A) original bit of coding input is:
Present embodiment is an example, and system of the present invention is not limited to present embodiment, and can also there be other execution mode in system of the present invention.
Above content is to combine concrete execution mode to the further explain that the present invention did, and can not assert that practical implementation of the present invention is confined to these explanations.For the those of ordinary skill of technical field under the present invention, under the prerequisite that does not break away from the present invention's design, can also make some simple deduction or replace, all should be regarded as belonging to protection scope of the present invention.
