Description
Technical field
The present invention relates to wireless communication field, particularly a kind of multi-channel multiplexing transmission technology.
Background technology
Based on OFDM (OFDM; Orthogonal Frequency Division Multiplexing) in the uplink single-carrier frequency division multiple access access to wireless communication system of technology; At uplink direction; Be the direction of user terminal to the network side emission, user terminal need transmit different upstream control signalings gives network side.For example, in Long Term Evolution (3GPPLTE, 3 of 3G (Third Generation) Moblie partner program project
RdGeneration Partnership Project Long Term Evolution) in the system; These upstream control signalings have affirmation/deny (ACK/NACK; ACKnowledgement/Non-ACKnowledgement) information, channel quality indication (CQI, Channel Quality Indicator) information, multiple-input and multiple-output (MIMO; Multiple Input Multiple Output) relevant aerial information, and uplink scheduling solicited message or the like.
It is bright specifically that hereinafter is with CQI information and ACK/NACK information that example is carried out.CQI information is used for the downlink channel quality situation of informing user terminal institute perception, carries out link circuit self-adapting and frequency selective scheduling to help network side (base station).Communication system is carried out the feedback of CQI usually according to the distinctive cycle.ACK/NACK information is used for communicating pair and confirms whether communication is successful.In FDD (FDD, Frequency Division Duplexing) system, if user terminal once receives only a code word, user terminal only feeds back an ACK/NACK at every turn so; If user terminal has once received a plurality of code words, for example adopted the MIMO technology, user terminal can once feed back a plurality of ACK/NACK so.In time division duplex (TDD, Time Division Duplexing) system, user terminal also can once feed back a plurality of ACK/NACK of the data that receive about a plurality of descending moment a up moment.
Whether send CQI information and ACK/NACK information is independent of transmitting uplink data, whether send also separate between these two upstream control signalings.Usually, when certain user terminal has only CQI information to send or has only the ACK/NACK informational needs to send, will on the specific resource that distributes separately for them, transmit, corresponding specific resource is called this user's CQI channel or ack channel respectively.When this user terminal had two or more upstream control signalings to launch simultaneously, in order to keep the uplink single-carrier property of 3GPP LTE communication system, these two or more upstream control signalings should carry out multiplexing sending afterwards.Said single-carrier property can guarantee the lower peak-to-average force ratio that transmits, and information transmitted is sent on the identical frequency resource according to same operating process but need simultaneously.
Generally, communication system has certain transmission quality requirements for various control signalings.For example; In the 3GPPLTE system, when ACK/NACK and CQI were multiplexing, the false dismissal probability of ACK should be no more than 1%; NACK should be no more than 0.01% to the false dismissal probability of ACK; The error probability of CQI should be no more than 1%, and the discontinuous transmission of ACK/NACK when the downlink resource assignment signalling is made mistakes (DTX, Discontinuous Transmission) flase drop is that the probability of ACK should be no more than 1%.ACK/NACK DTX flase drop was that ACK refers to following a kind of situation when above-mentioned downlink resource assignment signalling was made mistakes: when descending resource allocation signal is not correctly received by the user; The user can not feed back about the corresponding ACK/NACK signaling of the packet of this scheduling, but the base station and do not know this moment the user lost this resource allocation signal.If there is this moment user's periodicity CQI informational needs to transmit just; Then the user has in fact only sent CQI information; Yet this moment, the mode that transmits can be mixed by ACK/NACK and CQI in the base station; From the pure CQI information that receives, demodulate ACK/NACK information and CQI information, thereby a part of information of CQI is come out as the ACK/NACK demodulates information, and flase drop has gone out ACK.
Situation to the above-mentioned upstream control signaling that two or more is arranged need be launched has proposed a kind of signal method for transmitting in the prior art.In this launching technique: CQI information adopts the OFDM (DFT-S-OFDM based on DFT; Discrete Fourier Transfbrm-Spread-Orthogonal Frequency Division Multiplexing) the piece spread spectrum transmission structure of technology; When ACK/NACK and CQI transmit simultaneously; With ACK/NACK and CQI at DFT (DFT; Discrete Fourier Transform) it is multiplexing to carry out modulation symbol level before, on the CQI of this user terminal channel resource, transmits then.This multiplexing transmission mode provides possibility for satisfying above-mentioned ACK/NACK and CQI transmission quality requirements.But said method is a kind of framework of multiplexing transmission mode, and a kind of concrete multiplexing transmission processing method of modulation symbol level also is not provided, and makes receiving terminal can distinguish these multiple connections information transmitted together the time preferably.

The situation of launching simultaneously with 3GPP LTE system and ACK/NACK information and CQI informational needs below is an example, introduces.
The uplink frame structure of 3GPP LTE system is: when short Cyclic Prefix (CP, Cyclic Prefix), constitute the time slot of a long 0.5ms by 7 continuous OFDM symbols, two continuous time slot constitute the subframe of a long 1ms.OFDM symbol on the frequency domain by wide for the frequency-region signal on the subcarrier of 15kHz constitutes, on time domain, constitute by a plurality of time sampling signals.In this specific embodiment, upstream control signaling takies the running time-frequency resource of N OFDM symbol and M continuous subcarrier in a sub-frame.Take M continuous subcarrier and mean that upstream control signaling through after the coded modulation, is made up of M modulation symbol in the OFDM symbol.
Under the short CP uplink frame structure of above-mentioned 3GPP LTE system, M=12 usually, N=14.With reference to figure 1, be the sketch map of a frame structure in this case.Among Fig. 1, comprise the white box of digital i, i is 0 to 11 natural number, representes the OFDM symbol of i non-pilot tone; The grey square frame, expression is as the OFDM symbol of pilot tone; The white box that comprises digital Sj, j is 0 to 11 natural number, representes j modulation symbol in the OFDM symbol.Can see that upstream control signaling is made up of 14 OFDM symbols in a sub-frame, 2 OFDM symbols are wherein arranged as pilot tone, and each OFDM symbol be made up of 12 modulation symbols.
Provide signal transmission processing method below to above-mentioned frame structure.In this execution mode,, when having only CQI information to send or having only the ACK/NACK informational needs to send, will in system the proprietary CQI channel or the ack channel transmitted over resources of its distribution to a certain subscriber equipment; When having ACK/NACK and CQI information to send at the same time, ACK/NACK and CQI adopt the multiplexing back of modulation symbol level on the CQI of this subscriber equipment channel resource, to transmit.Like this, to the proprietary CQI channel resource of subscriber equipment, wherein the modulation symbol of some position sends CQI information when this subscriber equipment has only CQI information; When this subscriber equipment has ACK/NACK and CQI information to send simultaneously, the ACK/NACK information behind transmission and the CQI information multiplexing.To both of these case, ACK/NACK information and CQI transmission of Information to same subscriber equipment on the modulation symbol of these positions are modulated the discrimination that provides enough through different sequences.
In the process of actual transmissions, the CQI transmission of Information has following two kinds of situation, and a kind of situation is that CQI information original bit is fewer, and after coding and rate-matched, an OFDM symbol that can in a sub-frame, take has been uploaded.Another kind of situation is that CQI information original bit number is more, after coding and rate-matched module, need be divided into a plurality of parts, has uploaded at a plurality of OFDM symbols.This embodiment will be introduced to first kind of situation.
In the description process below, m representes the modulation symbol number that ACK/NACK information takies in an OFDM symbol, and CQI information has taken remaining M-m; N representes the number of the coded information bits that a modulation symbol carries, and promptly ACK/NACK information and CQI information adopt the mode of n contrast system; L representes to be used for the number of the OFDM symbol of pilot transmission, and remaining N-L OFDM symbol is used for ACK/NACK information and CQI transmission of Information.With reference to figure 2, its detailed process is following:
Concrete, ACK/NACK exports long for the encoding block of m*n after encoding, and is designated as A

s(1) ..., a
s(m-1) }; Aforementioned CQI information through punching is carried out n contrast system, forms (M-m) individual CQI modulation symbol, is designated as C
s={ c
s(0), c
s(1) ..., c
s(M-m-1) }.
Concrete, above-mentioned sequence modulation process is: use length respectively each modulation symbol to be carried out the operation of similar spread spectrum as the sequence of N-L, the modulation symbol of different information adopts different modulation sequences, and the different modulating symbol of same information adopts identical modulation sequence.More specifically, to each ACK/NACK modulation symbol a
s(j), j=0,1 ..., m-1 uses long modulation sequence P as N-L
a={ p
a(0), p
a(1) ..., p
a(N-L-1) } modulate, obtain PA
j={ p
a(0) a
s(j), p
a(1) a
s(j) ..., p
a(N-L-1) a
s(j) }.Each element that this sequence modulation is with modulation sequence multiplies each other with this ACK/NACK modulation symbol.
Same, to each CQI modulation symbol c
s(j), j=0,1 ..., M-m-1 uses long modulation sequence P as N-L
c={ p
c(0), p
c(1) ..., p
c(N-L-1) } modulate, obtain PC
j={ p
c(0) c
s(j), p
c(1) c
s(j) ..., p
c(N-L-1) c
s(j) }.
Thereby the sequence modulation module has been exported the individual new modulation symbol of m* (N-L), and wherein, the new modulation symbol of the ACK/NACK of k OFDM symbol is designated as PA
0(k), PA
1(k) ..., PA
M-1(k), 0≤k≤N-L-1; Exported the new modulation symbol of the individual CQI of (M-m) * (N-L) simultaneously, wherein, the new modulation symbol of the CQI of k OFDM symbol is designated as PC
0(k), PC
1(k) ..., PC
M-m-1(k), 0≤k≤N-L-1.
Preferable, in this execution mode, can distinguish aforementioned modulation sequence P at receiver side better in order to make ACK/NACK information and CQI information
aAnd P
cSatisfy mutually orthogonal relation.Below several groups of modulation sequences be exactly the example that satisfies mutually orthogonal relation:
First group of modulation sequence: the corresponding sequence of ACK/NACK information is P
a=1,1,1,1,1,1 ,-1 ,-1 ,-1 ,-1 ,-1, and-1}, the corresponding sequence of CQI information is P
c=1,1,1,1,1,1,1,1,1,1,1,1}.
Second group of modulation sequence: the corresponding sequence of ACK/NACK information is P
a=1 ,-1,1 ,-1,1 ,-1,1 ,-1,1 ,-1,1, and-1}, the corresponding sequence of CQI information is P
c=1,1,1,1,1,1,1,1,1,1,1,1}.
The 3rd group of modulation sequence: the corresponding sequence of ACK/NACK information is P
a=1,1,1 ,-1 ,-1 ,-1 ,-1 ,-1 ,-1,1,1, and 1}, the corresponding sequence of CQI information is P
c=1,1,1,1,1,1,1,1,1,1,1,1}.
The 4th group of modulation sequence: the corresponding sequence of ACK/NACK information is P
a=1,1,1 ,-1 ,-1 ,-1,1,1,1 ,-1 ,-1, and-1}, the corresponding sequence of CQI information is P
c=1,1,1,1,1,1,1,1,1,1,1,1}.
As the sequence such as the P that use one complete 1
c={ 1,1,1,1,1,1,1,1,1,1,1,1} modulates the modulation symbol of input, is equivalent to one group of modulation symbol of input is carried out repetition, and this moment, this sequence modulation processing procedure in reality realizes can use " repetition " to replace.
For dissimilar control signalings; Be ACK/NACK information and the CQI information in the present embodiment; Between their modulation sequence during mutually orthogonal, can regard as the dissimilar control signalings of same subscriber equipment are used and carry out spread spectrum on the long N-L of mutually orthogonal spreading code in the subframe OFDM symbol and operate as N-L.
Concrete, modulated sequence P
aM the ACK/NACK modulation symbol and the modulated sequence P of same element interaction
cM-m the CQI modulation symbol multiple connection in sequence of that element interaction of same position get up, form a M modulation symbol that the OFDM symbol is required.This certain sequence is meant the order of the modulation symbol position that multiplexing back ACK/NACK and CQI take.
That is the new modulation symbol PA of above-mentioned ACK/NACK,
0(k), PA
1(k) ..., PA
M-1(k) and the new modulation symbol PC of CQI
0(k), PC
1(k) ..., PC
M-m-1(k) carry out multiple connection, form M modulation symbol of k OFDM symbol, wherein 0≤k≤N-L-1.
The order of two kinds of information multiple connections can be undertaken by the order that system needs, for example, ACK/NACK information can multiple connection before CQI information, also can multiple connection after, can also multiple connection in the middle of a plurality of modulation symbol sequences of CQI.
For the sake of simplicity, the processing procedure that does not comprise pilot signal in the flow process shown in Figure 2.
The modulation symbol that the process of process above-mentioned steps 101-105 forms is handled according to other signal processing method of the prior art and is formed armed signal, and launches.
For example; In this execution mode; Can adopt the signal emission process of the expansion OFDM based on DFT as shown in Figure 3 (DFT-S-OFDM, Discrete Fourier Transform-Spread-Orthogonal Frequency Division Multiplexing) structure.This process can be summarized as:
The information via coding and the modulation of step 11, user terminal obtain modulation symbol.
Step 12, this modulation symbol and pilot frequency sequence obtain frequency-region signal through DFT (DFT, Discrete Fourier Transform) earlier.
Step 13, be placed on the correspondent frequency resource, obtain frequency band that this correspondent frequency resource of frequency-region signal in the effective system bandwidth promptly forms by continuous subcarrier or the frequency resource that forms of subcarrier uniformly-spaced through subcarrier mapping frequency-region signal with output.
In the aforementioned subcarrier mapping process, for the control signaling, the subcarrier mapping block can be realized the resource occupation mode of upstream control signaling in last lower sideband frequency hopping; For data-signal, the subcarrier mapping block is placed into it on the data resource of system's this moment to this user terminal distribution.
Step 14, form the frequency-region signal in the whole transmitted bandwidth through adding empty subcarrier.
Step 15, convert frequency-region signal to time-domain signal through contrary FFT (IFFT, Inverse Fast Fourier Transform).
Step 16, through adding behind the Cyclic Prefix again through becoming frame module promptly to obtain transmitting of subscriber equipment.The process of step 11-16 is a prior art, thereby does not give unnecessary details at this.
That is to say that in implementation process, after step 101-105 was finished, the modulation symbol that obtains continued execution in step 12-16 again as the said modulation symbol in the above-mentioned steps 12.
Above-described is the signal emission process based on the DFT-S-OFDM structure of a subscriber equipment.In real system, the upstream control signaling that a plurality of subscriber equipmenies can be arranged is multiplexed in the identical upstream control signaling Resource Unit with the mode of code division multiplex.Under upstream control signaling transmission structure, when a plurality of subscriber equipmenies transmit upstream control signaling simultaneously, can realize between the user multiplexing through the mode of piece spread spectrum based on DFT-S-OFDM.With reference to figure 4, provided a sketch map based on piece spread spectrum between the user of frame structure shown in Figure 1.Among Fig. 4, represent i non-pilot tone OFDM symbol with the white box of digital i, the grey square frame is with Sk as the OFDM symbol of pilot tone, and the white box of l is represented the 1st element, wherein 1≤l≤6 of the piece spreading code of user k.The length of the piece spreading code of subscriber equipment is 6 among Fig. 4; Can see that from Fig. 4 the operation of piece spread spectrum is actually and lets M the modulation symbol of upstream control signaling in an OFDM symbol of subscriber equipment multiply by this subscriber equipment simultaneously at the corresponding piece spreading code element of this OFDM character position between the user.Piece spread spectrum between above-mentioned a plurality of subscriber equipment also is a prior art, thereby does not give unnecessary details at this.
That is to say, in the actual process of transmitting, when a plurality of users are multiplexing, carry out the processing procedure of step 101-105 earlier, carry out the piece spread spectrum operation of the described a plurality of subscriber equipmenies of Fig. 4 again, launch according to the described DFT-S-OFDM emission process of Fig. 3 then.
The front is described is the situation of ACK/NACK information during with CQI informational needs multiplexing transmission together, when not having ACK/NACK information, is the CQI message processing flow among Fig. 2 to CQI information processing flow process, and this two goes on foot processing but do not comprise punching and multiple connection.
Preferable, to the different values with a kind of information, for example ACK/NACK can use different sequences to modulate when value is respectively ACK and NACK; Modulation symbol to the different values of output after a kind of information via modulation also can use different sequences to modulate.
Provide the method for a concrete example below to explain that above-mentioned signal emission is handled.With reference to the time-domain signal structure chart of upstream control signaling in a sub-frame shown in Figure 1, M=12, N=14, L=2 in this instantiation, and m=2, n=2.Be that ACK/NACK information after multiplexing takies the 0th and the 1st modulation symbol, and adopt the QPSK modulation.The process of above-mentioned steps 101-105 is specially the process of following step 201-205:
In step 201, coding and the rate-matched module, ACK/NACK output length after coding and rate-matched is the encoding block of 4 bits; CQI output length after coding and rate-matched is the encoding block of 24 bits.
Step 202, because CQI wants and ACK/NACK is multiplexed on 12 modulation symbol positions, so the punching module is punched into 20 bits of encoded pieces with CQI according to the occupancy mode of ACK/NACK.
Step 203, process modulation module form 2 ACK/NACK modulation symbols and are designated as A
s={ a
s(0), a
s(1) } and 10 CQI modulation symbols, is designated as and C
s={ c
s(0), c
s(1) ..., c
s(9) }.
Step 204, sequence modulation module are carried out sequence modulation.
Concrete, to each ACK/NACK modulation symbol, use length is 12 sequence P
a={ 1,1,1,1,1,1 ,-1 ,-1 ,-1 ,-1 ,-1 ,-1} modulation is also promptly multiplied each other with each element and the ACK/NACK modulation symbol of modulation sequence.Like this, phase place and phase place latter half in of the new modulation symbol of each ACK/NACK in the first half of whole subframe is the upset relation, and promptly phase difference is π.To each CQI modulation symbol, use length is 12 sequence P
c=1,1,1,1,1,1,1,1,1,1,1, the 1} modulation.The phase place of each new CQI modulation symbol in the first half of whole subframe is identical with phase place in the latter half like this.Thereby sequence modulation module 24 new modulation symbols of ACK/NACK of output and 120 new modulation symbols of CQI constitute the useful information in 12 OFDM symbols in the sub-frame.
Step 205, by sequence P
a Same element interaction 2 ACK/NACK modulation symbols and by sequence p
cThe order multiple connection of the modulation symbol position that takies by multiplexing back ACK/NACK and CQI of 10 CQI modulation symbols of that element interaction of same position, form 12 modulation symbols that the OFDM symbol is required.
After the processing of this execution mode step 201-205, obtain the PHASE DISTRIBUTION figure in all the available OFDM symbols in the sub-frame shown in Fig. 5 (a).Available OFDM symbol is meant ..., for example the 0th～2,4～9,11～13 among Fig. 1, totally 12 OFDM symbols.If what this subframe was carried is CQI information, then the modulation symbol constellation point of certain position of all the available OFDM symbols in this subframe has identical phase place and amplitude.Shown in Fig. 5 (a); The phase place of carrying CQI information for
modulation symbol phase place after sequence modulation all be
when adopting QPSK to modulate;
but value π/4; 3 π/4; 5 π/4,7 π/4.If what carry is ack/nack signal; Then the modulation symbol constellation point phase place of this position of all the OFDM symbols within the first half in this subframe is identical; The modulation symbol constellation point phase place of this position of all the OFDM symbols within the latter half is identical; But the phase overturn that has π between first half and the latter half, i.e. phase phasic difference ± π.
To carrying the 0th and the 1st modulation symbol of ACK/NACK information, their θ value can be identical, also can be different.Suppose identical and θ=π/4 of θ value, ACK/NACK is output as 0000 for ACK behind the time coding in value so, is output as 1111 behind the coding in value during for NACK.With reference to figure 5a; The modulation symbol of certain position is carrying respectively under ACK/NACK information or the CQI information both of these case; When
or
; There are 6 phase places on the modulation symbol different, when
and
has 12 phase places on the modulation symbol different.Use other upstream control signaling information representation CQI information among this Fig. 5 a.
Similarly, Fig. 5 b is that the corresponding sequence of ACK/NACK information is P
a=1,1,1 ,-1 ,-1 ,-1,1,1,1 ,-1 ,-1, and-1}, the corresponding sequence of CQI information is P
c=1,1,1,1,1,1,1,1,1,1,1, the PHASE DISTRIBUTION figure of the information after the modulation during 1}.
Can know through above-mentioned analysis; Phase place on the modulation symbol is different; So just between ACK/NACK and other upstream control signaling (like CQI information), enough guard spaces are provided, can be fairly simplely when receiver side realizes that the downlink resource assignment signalling is made mistakes ACK/NACK DTX flase drop be that the probability of ACK is less.
Explained later above-mentioned when receiver side realizes that the downlink resource assignment signalling is made mistakes ACK/NACK DTX flase drop be the less detailed process of probability of ACK.At receiver side, current upstream control signaling kind of sending from a certain subscriber equipment is at first judged in the base station, if this upstream control signaling kind of base station judges is an ACK/NACK information, then on the ack channel resource of this subscriber equipment, receives this ACK/NACK information; If this upstream control signaling kind of base station judges is a CQI information, then on the CQI of this subscriber equipment channel resource, receive this CQI information; If base station judges will receive ACK/NACK and CQI information simultaneously, then come to receive respectively ACK/NACK and CQI information on the channel resource after this subscriber equipment ACK/NACK and CQI are multiplexing.For the reception of multiplexing back ACK/NACK and CQI information, the base station at first will extract the modulation symbol that carries ACK/NACK information and carry CQI information respectively from the time-domain signal of separating out; For the modulation symbol of those positions of carrying ACK/NACK information, the base station need judge whether its constellation point distribution meets the constellation point distribution rule that transmitting terminal is set.Only be ACK/NACK information and just think the ACK information that has received feedback from this subscriber equipment when successfully solving ACK what base station judges thought that these position modulation symbols carry; The constellation point distribution rule when if the information that base station these position modulation symbols of discovery carry does not satisfy the transmission of ACK/NACK information; Think that then the ACK/NACK message transmission makes mistakes; Even the base station can judge in view of the above that this information possibly be CQI information, and draws user terminal and receive the conclusion that the downlink resource assignment signalling is made mistakes.When sequence modulation adopt be orthogonal sequence the time, the base station to each information whether meet constellation point respectively the judgement of rule can realize with despreading.
Simultaneously, ACK and the NACK phase place on correspondence position is all inequality, also can guarantee the receptivity of ACK/NACK well.Simultaneously; The modulation symbol that carries certain position of ACK/NACK information all has identical phase place and amplitude in the first half inside of subframe respectively with latter half inside; When the piece spread spectrum of multiuser multiplexing occurs within subframe first half and the latter half, just can not destroy the orthogonality between a plurality of subscriber equipmenies behind the subsequent block spreading code spread spectrum.

For example; In the QPSK modulation of Fig. 1 a; Constellation point is carried out the rotation of π phase place can be realized for-1 through the modulation sequence element that is provided with in the execution mode one; " 00 " bit before also can in this execution mode, will modulating is mapped as " 11 " by code word, " 01 " bit is mapped as " 10 " etc. by code word.
Step 304, modulation.
Concrete, aforementioned through the new encoding block of ACK/NACK after the code word mapping
Carry out n contrast system, form the individual ACK/NACK modulation symbol of m* (N-L), wherein by i encoding block
I=0,1 ..., m the modulation symbol of exporting after the N-L-1 process n contrast system is designated as
Aforementioned through the new encoding block of CQI after the code word mapping

Embodiment three
In the above-mentioned execution mode, a modulation symbol Transmission Time Interval of two kinds of information is isometric, such as all in a sub-frame, transmitting.When every kind of information modulation symbol Transmission Time Interval separately is not isometric; Can all press the two modulation sequence of minimum transmission time Design of length at interval; Also can all press the two modulation sequence of maximum transmission time Design of length at interval; Also can be respectively by the Design of length modulation sequence of modulation symbol Transmission Time Interval separately, in the common Transmission Time Interval of two kinds of information, can carry out enough differentiations as long as guarantee with constellation point.Present embodiment has promptly been described when every kind of information modulation symbol Transmission Time Interval separately is not isometric respectively by the processing mode of the Design of length modulation sequence of modulation symbol Transmission Time Interval separately.
What previous embodiment one, two was introduced is that CQI information original bit is fewer, through after coding and the rate-matched, and M the situation that continuous subcarrier has passed of an OFDM symbol that can in a sub-frame, take with upstream control signaling; This execution mode will be more to CQI information original bit number; After coding and rate-matched module; Need be divided into a plurality of parts and could it have been passed, cause ACK/NACK and the CQI information not isometric situation of modulation symbol Transmission Time Interval separately to introduce at a plurality of OFDM symbols.At this moment, a CQI modulation symbol only transmits on the available OFDM symbol of the part of a frame, and the modulation symbol of ACK/NACK still transmits on the whole available OFDM symbol of a frame.Here, suppose to export the long K that is after CQI information via coding and the rate-matched
c* the encoding block of M*n bit is exported the long K that is after punching
c* the encoding block of (M-m) * n bit, wherein 1＜K
c≤N-L.
The key step of an embodiment of the present invention is identical with the key step 101-103 of aforementioned embodiments one.Be that with the main distinction step 104 replaces with based on the execution mode one of sequence modulation:
Consider that the CQI modulation symbol number that can carry on each OFDM symbol of multiplexing back all is M-m, thereby will pass through the K that exports after the n contrast system
c* (M-m) individual modulation symbol C
s={ c
s(0), c
s(1) ..., c
s(K
c* (M-m)-1) } be divided into K
cThe group modulation symbol, every group comprises M-m CQI modulation symbol, and M-m CQI modulation symbol of i group is designated as
I=0 wherein, 1 ..., K
c-1.To M-m CQI modulation symbol of i group
Suppose that it has taken at N-L non-pilot tone OFDM symbol that is used for the upstream control signaling transmission of subframe at last
Individual OFDM symbol then has
And
When doing the sequence modulation,,, be designated as p so its modulation sequence length is N-L still because the modulation symbol of ACK/NACK is on all available OFDM symbols of whole subframe, to carry
a(i), i=0,1 ..., N-L-1.As far as CQI; Its i M-m CQI modulation symbol of group
only carries on certain
individual OFDM symbol; Use long modulation sequence
to modulate, obtain M-m the new modulation symbol of CQI that transmits in each corresponding OFDM symbol for
.
Step 105 replaces with: according to the position of the OFDM symbol that carries every group of M-m of CQI new modulation symbol, respectively with corresponding OFDM symbol on the ACK sequence modulation after new modulation symbol multiple connection.
Although two kinds of information this moment modulation sequence length separately is inequality, but still need make two kinds of information of the interior transmission of a sub-frame to distinguish through the difference of constellation point after the sequence modulation, special, can distinguish through not isometric orthogonal sequence modulation.
Provide a concrete example below to explain above-mentioned signal method for transmitting.
Step 501, coding and rate-matched.The encoding block of ACK/NACK output 4 bits after coding and rate-matched; The encoding block that after coding and rate-matched, is output as long 24 bits with CQI in the step 201 is different, because the original information bits of CQI information is more, and coding and the long 48 bits of encoded pieces of rate-matched module output.
Step 502, punching.With in the step 202 with CQI information coded bit punching be 20 bits different be in this step, to be 40 bits with the punching of CQI information coded bit.
Step 503, modulation.ACK/NACK information is 2 modulation symbols of output after the QPSK modulation; CQI information is 20 modulation symbols of output after the QPSK modulation.
According to the example of different modulation sequences, step 504 sequence modulation afterwards and the process of step 505 multiple connection are described below:
Example one: 20 modulation symbols of step 5041, CQI information are divided into two groups, and 10 every group, first group of interior modulation symbol need be carried on the 0th～2,6～8 the OFDM symbol, and second group of interior modulation symbol need be carried on the 3rd～5,9～11 the OFDM symbol.Every group is all used length is 6 sequence P
c={ 1,1,1,1,1,1} modulates, and obtains 120 new modulation symbols of CQI altogether, 60 every group; 2 modulation symbols use length of ACK information are 12 sequence P
a={ 1,1,1,1,1,1 ,-1 ,-1 ,-1 ,-1 ,-1 ,-1} modulates in whole subframe, obtains 24 new modulation symbols of ACK/NACK.
Step 5051, CQI first group and second group each 10 are placed on the 0th～2,6～8 and the 3rd～5,9～11 the OFDM symbol of subframe respectively and are carried out multiple connection through the new modulation symbol of ACK/NACK that obtains after the sequence modulation on the corresponding OFDM symbol through the new modulation symbol that obtains after the sequence modulation.Can obtain the dissimilar upstream control signaling information shown in Figure 6 PHASE DISTRIBUTION sketch map on each OFDM symbol in a sub-frame this moment, and wherein CQI information informational needs behind modulating-coding could pass with two OFDM symbols.The main feature of PHASE DISTRIBUTION shown in Figure 6 is the modulation symbol for certain position, if what carry is CQI information, then subframe latter half content is the repetition of subframe first half content; If what carry is ACK/NACK information, then has phase phasic difference ± π between identical phase place, subframe first half and the subframe latter half within subframe first half and the latter half.In Fig. 6; The modulation symbol of certain position is carrying respectively under ACK/NACK information and the CQI information both of these case; No matter
and θ be value how, still has the phase place difference of 6 modulation symbols at least.
Example two: 20 modulation symbols of step 5042, CQI information are divided into two groups, and 10 every group, first group of interior modulation symbol need be carried on the 0th～5 the OFDM symbol, and second group of interior modulation symbol need be carried on the 5th～11 the OFDM symbol.Every group is all used length is 6 sequence P
c={ 1,1,1,1,1,1} modulates, and obtains 120 new modulation symbols of CQI altogether, 60 every group; 2 modulation symbols use length of ACK information are 12 sequence P
a=1,1,1 ,-1 ,-1 ,-1 ,-1 ,-1 ,-1,1,1,1} or P
a={ 1,1,1 ,-1 ,-1 ,-1,1,1,1 ,-1 ,-1 ,-1} modulates.
On step 5052, CQI first group and second group 10 first half and the latter halfs that are placed into subframe through the new modulation symbol that obtains after the sequence modulation respectively and carry out multiple connection through the new modulation symbol of ACK/NACK that obtains after the sequence modulation on the corresponding OFDM symbol.Just can obtain the PHASE DISTRIBUTION of modulation symbol when carrying dissimilar upstream control signaling after the multiple connection like Fig. 7, certain position shown in 8.
That shown in Figure 7 is P
a={ 1,1,1 ,-1;-1 ,-1 ,-1 ,-1;-1,1,1, the PHASE DISTRIBUTION figure during 1}; Main feature is the modulation symbol to certain position, if what carry is ACK/NACK information, then saltus step is arranged and phase overturn between subframe first half and latter half in phase place within subframe first half and the latter half; If what carry is CQI information, what then subframe latter half and first half carried is different modulation symbols.That shown in Figure 8 is P
a={ 1,1,1 ,-1;-1 ,-1,1,1; 1 ,-1 ,-1, the PHASE DISTRIBUTION figure during-1}; The main feature of PHASE DISTRIBUTION is the modulation symbol to certain position, if what carry is ACK/NACK information, then has between saltus step and subframe latter half and the first half phase place identical in phase place within subframe first half and the latter half; If what carry is CQI information, what then subframe latter half and first half carried is different modulation symbols.In Fig. 7, Fig. 8; The modulation symbol of certain position is carrying respectively under ACK/NACK information and the CQI information both of these case; No matter
and θ be value how, still has the phase place difference of 6 modulation symbols at least.
The key step 301,302,304,305 of the key step of another embodiment of the present invention and aforementioned embodiments two is identical.Be that with the main distinction of the execution mode two that shines upon based on code word step 303 replaces with:
Consider that the CQI modulation symbol number that can carry on each OFDM symbol of multiplexing back all is M-m, thereby output length is K after punching
c* the encoding block of (M-m) * n bit is divided into K
cIndividual sub-encoding block, every group all is the long sub-encoding block of (M-m) * n bit that is, and the CQI encoding block of i long (M-m) * n bit is designated as
I=0 wherein, 1 ..., K
c-1.CQI encoding block to long (M-m) * n of i bit
Suppose that it has taken at N-L non-pilot tone OFDM symbol that is used for the upstream control signaling transmission of subframe at last
Individual OFDM symbol then has
And
When doing the code word mapping, with sub-encoding block
Be mapped to
Individual long be the new encoding block of CQI of (M-m) * n bit

Through its modulation sequence
Encoding block does before the modulation of the n contrast system constellation point of the M-m after the effect new CQI modulation symbol correspondence
New CQI encoding block after code word mapping so
Be above-mentioned encoding block
Top method mainly all is to introduce to the situation of an ACK/NACK of each feedback.Can have following three kinds of methods to support for the situation that has a plurality of ACK/NACK to feed back simultaneously:
First method be with the K rank or more the different modulating constellation point after the high order modulation represent the different conditions of K ACK/NACK; Second method is to use the some locational modulation symbol after multiplexing to represent at least to each ACK/NACK, means that K ACK/NACK will take the modulation symbol of K diverse location after multiplexing with other upstream control signaling at least this moment; The third method is that above-mentioned two kinds of schemes are combined use.Introduce the process under the situation of dibit ACK/NACK with the example of abovementioned steps 501-505 below:
First method is to have four different phase after the QPSK modulation, and dibit ACK/NACK has four kinds of possible values, and four kinds of possible values are mapped to four outs of phase respectively.Second method is that the 0th modulation symbol carries one bit ACK/NACK raw information, and the 1st modulation symbol carries another bit ACK/NACK raw information.
Embodiment four
The execution mode of front is the process that transmitting terminal such as user terminal are launched, and is corresponding with it, provides receiver side to receive the process of processing in this execution mode.In this execution mode; Multiplexing different information together to transmitting terminal adopt different modulation sequences to carry out the solution sequence modulation; The element of said different modulation sequence is the complex conjugate of correspondence position element of the modulation sequence of transmitting terminal, and the modulation sequence of said transmitting terminal makes said different information in a plurality of symbols of common Transmission Time Interval, demonstrate different constellation point to distribute.Still be that example is introduced with ACK/NACK information and CQI channel in the 3GPP LTE system.
To receiver side, the current upstream control signaling kind that will receive from a certain user terminal is at first judged in the base station.If base station judges only need receive ACK/NACK information from this user terminal, then on the ack channel resource of this user terminal, receive ACK/NACK information; If base station judges is as long as receive CQI information from this user terminal, then on the CQI of this user terminal channel resource, receive CQI information; If base station judges will receive ACK/NACK and CQI information simultaneously from this user terminal, then receive ACK/NACK and CQI information on the channel resource after this user terminal A CK/NACK and CQI are multiplexing.When needing only reception ACK/NACK information or CQI information, the processing procedure of receiver side is identical with prior art, repeats no more at this.
To the multiplexing back ACK/NACK and the CQI information that receive, receiver side carries out the inverse operation of DFT-S-OFDM operating process shown in Figure 3 earlier, carries out the inverse operation of piece spread spectrum operation between user shown in Figure 4 again, obtains the interior time-domain signal of subframe of multiple connection as shown in Figure 1.The inverse operation of piece spread spectrum operation all is a prior art between the inverse operation of DFT-S-OFDM operating process and user, also repeats no more at this.What introduce below mainly is that receiver side is to the processing procedure through the time-domain signal in the subframe that obtains multiple connection behind the aforesaid operations.The receiver side handling process corresponding with the emission process of execution mode one is shown in figure 14, and detailed process is following:
Step 1401, separate multiple connection.
Concrete, from the individual modulation symbol of M* (N-L) of N-L OFDM symbol of a sub-frame, isolate individual CQI modulation symbol of (M-m) * (N-L) and the individual ACK/NACK modulation symbol of m* (N-L) according to the order of multiple connection.
Step 1402, solution sequence modulation.
Concrete, the process of solution sequence modulation is corresponding with the process of transmitting terminal sequence modulation.To the individual CQI modulation symbol of separating of (M-m) * (N-L), the solution sequence modulation module is used with transmitting terminal and is used sequence P
cThe complex conjugate sequence
Come the solution sequence modulation to obtain M-m CQI modulation symbol.To the individual ACK/NACK modulation symbol of separating of m* (N-L), the solution sequence modulation module is used with transmitting terminal and is used sequence P
aThe complex conjugate sequence
Come the solution sequence modulation to obtain m ACK/NACK modulation symbol.
To the individual ACK/NACK modulation symbol of separating of m* (N-L), the solution sequence modulation module will judge also whether its constellation point distribution pattern matees the constellation point distribution pattern of the ACK/NACK of transmitting terminal after the sequence modulation operation.If mate successfully, receiver side thinks that m the ACK/NACK modulation symbol that the solution sequence modulation obtains is effective ACK/NACK modulation symbol, continues subsequent operation.If coupling failure, receiver side think that m the ACK/NACK modulation symbol that the solution sequence modulation obtains is not effective ACK/NACK modulation symbol, that can stop that subsequent operation and judgement receive is NACK; Perhaps, receiver side thinks and user terminal this moment do not send ACK/NACK, and then judges user terminal and do not receive the corresponding downstream resource allocation signal and this partial information is carried out the solution sequence modulation again as CQI information.
Step 1403, demodulation.
Concrete, ACK/NACK modulation symbol and the CQI modulation symbol through the solution sequence modulation that receive are separated n contrast system.
Step 1404, filling.
Concrete, be filled to the inverse operation of punching, be used to recover the coded-bit of destroying.
Rate-matched is conciliate in step 1405, decoding.Separating rate-matched is to carry out according to actual conditions are optional.
Concrete, the inverse operation of rate-matched for coding and rate-matched conciliate in decoding, ACK/NACK information and CQI information that output receives.
Below by one with the specific embodiment one in the corresponding solution sequence modulated process of step 104 further illustrate.
To the individual CQI modulation symbol of separating of (M-m) * (N-L), use long modulation sequence as N-L
Come the solution sequence modulation, wherein sequence
Element be the modulation sequence P that transmitting terminal adopts
c={ p
c(0), p
c(1) ..., p
c(N-L-1) } complex conjugate of correspondence position element; The process of solution sequence modulation is will
All elements multiply each other with the CQI modulation symbol of separating from the same position of N-L OFDM symbol one by one, addition more just obtains the CQI modulation symbol of a reception.This operation repeats M-m time and just obtains M-m CQI modulation symbol that receives.
To the individual ACK/NACK modulation symbol of separating of m* (N-L), use long modulation sequence as N-L
Carry out the solution sequence modulation, wherein sequence
Element be that transmitting terminal adopts modulation sequence P
a={ p
a(0), p
a(1) ...., p
a(N-L-1) } complex conjugate of correspondence position element.The process of solution sequence modulation is: all elements with
multiplies each other with the ACK/NACK modulation symbol of separating from the same position of N-L OFDM symbol one by one; Addition more just obtains the ACK/NACK modulation symbol of a reception.This operation repeats m time and just obtains m ACK/NACK modulation symbol that receives.
If user terminal receives the failure of downlink resource assignment signalling and has sent a pure CQI information; Receiver side thinks that user terminal has sent ACK/NACK and CQI information simultaneously, thereby in separating the multiple connection process, the individual CQI modulation symbol of m* (N-L) is separated as the ACK/NACK modulation symbol.As sequence P
aAnd P
cWhen mutually orthogonal, after the ACK/NACK modulation symbol of separating being carried out the solution sequence modulation,, can obtain m amplitude and approach 0 modulation symbol if the ACK/NACK modulation symbol that separates is actually the CQI modulation symbol; If in fact the ACK/NACK modulation symbol that separates is exactly the ACK/NACK modulation symbol, can obtain m the modulation symbol that amplitude is very strong so.
If an amplitude thresholding is set for the modulation symbol that receives, only all then thinks effective ACK/NACK modulation symbol, otherwise think invalid ACK/NACK modulation symbol greater than this thresholding in the amplitude of the m that a receives modulation symbol.The probability that the discontinuous transmission flase drop of ACK/NACK is ACK when receiver side just can reduce the downlink resource assignment signalling effectively and makes mistakes like this.
Embodiment five
This embodiment provides the receiver side handling process corresponding with emission process shown in the execution mode two.In this execution mode; Different information to transmitting terminal adopt different decoded word mappings; Said decoded word is mapped as the inverse mapping of the mapping ruler that uses in the code word mapping of transmitting terminal, and the code word of said transmitting terminal is shone upon and made said different information in a plurality of symbols of common Transmission Time Interval, demonstrate different constellation point distributions.Detailed process is following:
Concrete, the ACK/NACK modulation symbol and the CQI modulation symbol that receive are separated n contrast system.
Concrete, the decoded word mapping block is the inverse mapping of the mapping ruler that uses in the transmitting terminal code word mapping block, and CQI information after the demodulation of separating and ACK/NACK information are exported CQI coded-bit and the ACK/NACK coded-bit that receives respectively.The decoded word mapping block is to the ACK/NACK information of input; To judge also whether its code word distribution pattern mates the code word distribution pattern of the ACK/NACK of transmitting terminal behind the code word map operation; If the match is successful; Receiver side can think that just the ACK/NACK coded-bit that the decoded word mapping obtains is effective ACK/NACK coded-bit, continues subsequent operation; If it fails to match; Receiver side thinks that the ACK/NACK coded-bit that the decoded word mapping obtains is not effective ACK/NACK coded-bit; Can stop subsequent operation and judge that receive is NACK, even can think that user terminal does not send ACK/NACK this moment and then the judges terminal does not receive the corresponding downstream resource allocation signal and this partial information is carried out the decoded word mapping again as CQI information.
Rate-matched is conciliate in step 1505, decoding.Separating rate-matched is to carry out according to actual conditions are optional.Identical with step 1405, do not give unnecessary details at this.
