Description

The transmission of response message and dispatch request indication information and method of reseptance and device
Technical field
The present invention relates to the communication technology, the transmission of especially a kind of response message and dispatch request indication information and method of reseptance and device.
Background technology
Mixing automatic repeat requests (Hybrid Automatic Repeat Request; Hereinafter to be referred as: HARQ) in the technology; Data receiver is after the data receiver sends data; The data receiver need feed back response message to data receiver, confirms whether correctly to receive the data of its transmission to data receiver.Concrete; The value of response message can be to confirm (Acknowledgement; Hereinafter to be referred as: ACK), deny (Negative-acknowledgement, hereinafter to be referred as: NACK) with discontinuous emission (Discontinuous Transmission, hereinafter to be referred as: DTX).Wherein, ACK representes that Data Receiving is correct, and NACK representes the Data Receiving mistake, and DTX representes not receive data.Third generation partner program (3rdGeneration Partnership Project; Hereinafter to be referred as: 3GPP) evolution whole world terrestrial wireless inserts (Evolved Universal Terrestrial Radio Access; Hereinafter to be referred as: E-UTRA) system; (Long Term Evolution is hereinafter to be referred as LTE) system to be also referred to as Long Term Evolution.In 3GPP E-UTRA or the LTE system; In up link (Uplink) direction; Subscriber equipment through Physical Uplink Control Channel (Physical Uplink Control Channel, hereinafter to be referred as: PUCCH), the correct response message that receives of downlink data that whether base station is sent to base station feedback.Wherein, will be used for subscriber equipment and be called the response message channel, be also referred to as the uplink ACK channel to the PUCCH of base station feedback response message channel.
The dispatch request indication (Scheduling Request Indicator, hereinafter to be referred as: SRI) information is used for subscriber equipment sends scheduling of resource from upstream data to base station requests.In the LTE system, the value of SRI information can be forward (Positive) SRI or negative sense (Negative) SRI.Wherein, forward SRI representes subscriber equipment to the base station requests ascending resource scheduling, and negative sense SRI representes that the user does not ask ascending resource scheduling.When SRI information was only transmitted in the base station, this SRI information was also through the PUCCH Channel Transmission at subscriber equipment.To be used for subscriber equipment and be called the SRI channel to the PUCCH channel of base station transmits SRI information.
At senior Long Term Evolution (Long Term Evolution-Advanced as further evolution of LTE system and enhanced system; Hereinafter to be referred as: LTE-A) in the system; Adopt carrier aggregation (Carrier Aggregation) technology; Be also referred to as spectrum aggregating (Spectrum Aggregation) technology or bandwidth expansion (Bandwidth Extension) technology, support wideer bandwidth, with satisfy International Telecommunications Union for the 4th generation the communication technology the peak data rate requirement.In carrier aggregation technology; The spectrum aggregating of two or more member carriers (Component Carrier) is obtained wideer transmission bandwidth together; Each member carrier wherein can be configured to be compatible with the LTE system; The frequency spectrum of each member carrier can be adjacent continuous frequency spectrum, can be the interior non-conterminous frequency spectrum of identical frequency band, even can be the discontinuous spectrum in the different frequency bands also.For the LTE subscriber equipment; Can only insert one of them member carrier and carry out data transmit-receive; And for the LTE-A subscriber equipment, can be according to ability and the business demand of self, a plurality of member carriers that insert wherein simultaneously carry out data transmit-receive; And, can be the uplink member carrier and the downlink member carrier of the different numbers of LTE-A user device configuration.
In carrier aggregation technology, each member carrier all has independently HARQ process.When the LTE-A subscriber equipment inserts a plurality of downlink member carrier simultaneously; To each downlink member carrier at Physical Downlink Shared Channel (Physical Dedicated Shared Channel; Hereinafter to be referred as: PDSCH) go up the data of transmitting, all want the corresponding response message of up feedback.When the possible state of the response message of needs feedbacks is N; Can through ack channel and an orthogonal phase shift coding (Quadrature Phase Shift Keying, hereinafter to be referred as: QPSK) N each state in the possible state represented in the combination of modulation symbol.For example: if subscriber equipment has inserted 4 downlink member carriers; Data to each downlink member carrier transmission; The reception condition that all will feed back independently these data is ACK, NACK or DTX, and then the possible state of the subscriber equipment response message that need feed back is total 3^4=81.For another example: if subscriber equipment has inserted 4 downlink member carriers; Data to each downlink member carrier transmission; The reception condition that all will feed back independently these data is ACK; Still NACK and one of DTX that is: do not distinguish NACK and DTX, and then to have 2^4=16 individual for possible the state of the subscriber equipment response message that need feed back.At present, feed back the state of response message through channel selecting method, that is: through predefined rule; Combination with an ack channel in a plurality of ack channels and a QPSK modulation symbol in a plurality of QPSK modulation symbol; Be expressed as: (ack channel, QPSK modulation symbol), represent a state of response message; And, come the state of the corresponding response message of this combination of up feedback through the QPSK modulation symbol in this combination of the transmission of the ack channel in the combination.When the base station receives upstream data; At first judge on which ack channel and received data; And which QPSK symbol identifies what receive on this ack channel be, according to the combination of the QPSK modulation symbol of this ack channel and transmission thereof, and the corresponding relation between the state of response message; Just can know the state of the response message of subscriber equipment feedback, thereby know the reception condition of subscriber equipment the data transmitted on the downlink sub-carrier.
When in same uplink member carrier, both having transmitted SRI information, when again the data of a plurality of downlink member carriers transmission being fed back corresponding response message, just how simultaneously there is the problem of response information transmission and dispatch request indication information.In order to address this problem, in the prior art, allocate in advance with channel selecting method in the identical SRI channel of ack channel number of possible state needs of expression response message, and set up the one-to-one relationship of ack channel and SRI interchannel.For example: corresponding first SRI channel SRI (1) of first ack channel ACK (1), corresponding second the SRI channel SRI (k) of k ack channel ACK (k), k are the integer greater than zero.When needing state and the negative sense SRI of response information transmission simultaneously; Earlier according to channel selecting method; Select the corresponding ack channel of the state of this response message waiting for transmission and the combination (ack channel, QPSK modulation symbol) of QPSK modulation symbol, the ack channel in the combination of supposing to select is ACK (m); M is the integer greater than zero, on ACK (m) channel, sends the QPSK modulation symbol in this combination.When needing state and the forward SRI of response information transmission simultaneously; Earlier according to channel selecting method; Select the corresponding ack channel of the state of this response message waiting for transmission and the combination of QPSK modulation symbol; Ack channel in the combination of supposing to select is ACK (m), obtains SRI (m) channel corresponding with this ACK (m) channel again, and on this SRI (m) channel, sends the QPSK modulation symbol in the combination.When the base station receives upstream data; According to being the value that on SRI channel or ack channel, has received data judgement SRI information; If on SRI (m) channel, received the QPSK symbol; SRI (m) channel is corresponded to ACK (m) channel, and according to the combination of the QPSK modulation symbol that sends on this ACK (m) channel and SRI (m) channel, and the corresponding relation between the state of response message; Know the state of the response message of subscriber equipment feedback, thereby know the reception condition of subscriber equipment the data transmitted on the downlink sub-carrier.
Because SRI information is used for subscriber equipment to base station requests dispatching uplink resource, and is relevant with the business demand of subscriber equipment, and irrelevant with the member carrier number of subscriber equipment access, therefore, each subscriber equipment only needs a SRI channel just enough.But because the base station is dynamic to the scheduling of subscriber equipment, that is: to need the moment of up feedback response message be dynamic to subscriber equipment; Then at synchronization; Response information transmission and SRI information simultaneously maybe be needed, also SRI information maybe be only transmitted, therefore; In order to support response information transmission and SRI information simultaneously, prior art is reserved a plurality of SRI channels for each subscriber equipment.
In realizing process of the present invention, the inventor finds that there is following problem at least in above-mentioned prior art is transmitted SRI information and response message simultaneously in same uplink member carrier method:
For each subscriber equipment has been reserved a plurality of SRI channels; When subscriber equipment need not be to the base station feedback response message; A plurality of SRI channels of reserving for subscriber equipment are left unused; And can't be used by other subscriber equipment, cause the utilance of bandwidth resources lower, caused the significant wastage of finite bandwidth resource allocation.

For example: as first ack channel, as second ack channel, then first preset rules between first ack channel and second ack channel can be that channel ACK (k) corresponds to channel ACK ((k+r) modM) with channel ACK ((k+r) modM) with channel ACK (k).Wherein, r be one greater than zero integer, M is the sum of first ack channel; (k+r) modM representes the remainder that is divided by and obtains behind k+r and the M delivery; For example: the k value is 2, and the r value is 1, and the M value is 4; Then the value of (k+r) modM is the remainder 3 after 2+1 and 4 is divided by, and then the matched rule between first ack channel and second ack channel is that channel ACK (2) corresponds to channel ACK (3).The value of supposing P is 1; The value of L and D is 2; Preset change rule is for to change to first subchannel in second ack channel with first subchannel in first ack channel; Then first subchannel among the channel ACK (2) is changed to first subchannel among the channel ACK (3); Then through second subchannel among the channel ACK (2) and first subchannel transmission first information symbol among the channel ACK (3); If preset change rule then changes to second subchannel among the channel ACK (3) with second subchannel among the channel ACK (2) for second subchannel in first ack channel is changed to second subchannel in second ack channel, then through first subchannel among the channel ACK (2) and the transmission of second subchannel among the channel ACK (3) first information symbol.
Particularly, when ack channel was pressed the time slot division subchannel in the LTE/LTE-A, the 0th slot s lot 0 was as first subchannel, and the 1st slot s lot 1 is as second subchannel.If preset change rule is for to change to first subchannel in second ack channel with first subchannel in first ack channel; Then first subchannel among the channel ACK (2) is changed to first subchannel among the channel ACK (3), then through second subchannel among the channel ACK (2) and first subchannel transmission first information symbol among the channel ACK (3); If preset change rule is for to change to second subchannel in second ack channel with second subchannel in first ack channel; Then second subchannel among the channel ACK (2) is changed to second subchannel among the channel ACK (3), then through first subchannel among the channel ACK (2) and the transmission of second subchannel among the channel ACK (3) first information symbol.
Perhaps; Particularly, when ack channel was divided subchannel according to antenna in the LTE/LTE-A or antenna opening, it was a subchannel that ack channel is used for two channels on each antenna of antenna; If preset change rule is with subchannel that antenna is corresponding in first ack channel; Suppose to be called first subchannel, change to subchannel that antenna is corresponding in second ack channel, suppose to be called first subchannel; Then first subchannel among the channel ACK (2) is changed to first subchannel among the channel ACK (3); Then, be modified on the antenna of corresponding subchannel, through first subchannel transmission first information symbol among second subchannel among the channel ACK (2) and the channel ACK (3); If preset change rule is for to change to second subchannel in second ack channel with second subchannel in first ack channel; Then second subchannel among the channel ACK (2) is changed to second subchannel among the channel ACK (3), then through first subchannel among the channel ACK (2) and the transmission of second subchannel among the channel ACK (3) first information symbol.Suppose according to preset change rule; First subchannel that first antenna is corresponding in first ack channel is changed to second first subchannel that antenna is corresponding in second ack channel; Then on first antenna, through first subchannel transmission first information symbol among second subchannel among the channel ACK (2) and the channel ACK (3).
Concrete, first ack channel specifically can be that all ack channel ACK (k) correspond to the SRI channel with first preset rules and the 3rd channel matched.The value of supposing P is 1; The value of L and D is 2; At this moment; Can first subchannel in first ack channel be changed to first subchannel in the SRI channel according to preset change rule, and through second subchannel in first ack channel that obtains and first subchannel transmission first information symbol in the SRI channel; Perhaps second subchannel in first ack channel is changed to second subchannel in the SRI channel, and through first subchannel in first ack channel that obtains and the transmission of second subchannel in SRI channel first information symbol.
Particularly, when ack channel and SR channel were divided subchannel according to the time slot in the LTE/LTE-A, the 0th slot s lot 0 was as first subchannel, and the 1st slot s lot 1 is as second subchannel.If according to preset change rule first subchannel in first ack channel is changed to first subchannel in the SRI channel, then through second subchannel in first ack channel and first subchannel transmission first information symbol in the SRI channel; If second subchannel in first ack channel is changed to second subchannel in the SRI channel, then through first subchannel in first ack channel and the transmission of second subchannel in channel SRI channel first information symbol according to preset change rule.
Perhaps, particularly, when ack channel and SRI channel are divided subchannel according to antenna in the LTE/LTE-A or antenna opening; It is a subchannel that ack channel is used for two channels on each antenna of antenna; It is a subchannel that the SRI channel is used for two channels on each antenna of antenna, if regular with the corresponding subchannel of one of them antenna in first ack channel according to preset change, supposes to be called first subchannel; Change to subchannel that antenna is corresponding in the SRI channel; Suppose to be called first subchannel, then first subchannel among the channel ACK (2) is changed to first subchannel in the SRI channel, then; Be modified on the antenna of corresponding subchannel, through second subchannel among the channel ACK (2) and first subchannel transmission first information symbol in the SRI channel; If preset change rule is for to change to second subchannel in the SRI channel with second subchannel in first ack channel; Then second subchannel among the channel ACK (2) is changed to second subchannel in the SRI channel, then through first subchannel among the channel ACK (2) and the transmission of second subchannel in SRI channel first information symbol.Suppose according to preset change rule; First subchannel that first antenna is corresponding in first ack channel is changed to second first subchannel that antenna is corresponding in the SRI channel; Then on first antenna, through second subchannel among the channel ACK (2) and first subchannel transmission first information symbol in the SRI channel.
With the 3rd channel; Comprise that second ack channel or SRI channel distribution are a plurality of subchannels; And distinguish the state of response message and SRI information through the mode of replacing in first ack channel corresponding P subchannel with the P subchannel in the 3rd channel, having significantly reduced need be the ack channel and the quantity of SRI channel of user terminal configuration, has avoided leaving unused, wasting of finite bandwidth resource; Further improve the utilance of bandwidth resources, saved the bandwidth resources expense.

Figure 13 is specially concrete an application embodiment illustrated in fig. 12 for the flow chart of an application implementation example of transmission method of ascending control information of the present invention, this embodiment.Shown in figure 13, this application implementation example specifically comprises:
Step 901. is at the bit number A of ascending control information waiting for transmission during greater than preset bit number 11 bits; Subscriber equipment is according to preset rule of classification; Ascending control information waiting for transmission is divided into two ascending control informations to divide into groups; These two ascending control informations groupings comprise X (1), the individual bit of X (2), wherein X (1)+X (2)=A respectively.
Concrete, transmitting terminal can be the LTE/LTE-A subscriber equipment.Ascending control information waiting for transmission can include but not limited in the following information any one or multiple: CQI (Channel Quality Indicator; Hereinafter to be referred as: CQI), pre-coding matrix indication (Precoding Matrix Index; Hereinafter to be referred as: PMI), the order designator (Rank Indicator, hereinafter to be referred as: RI), response message, SRI.
Wherein, the bit number that two ascending control informations divide into groups to comprise can be identical, also can be different.For example: when the bit number of ascending control information waiting for transmission was 20 bits, the ascending control information that can be divided into two 10 bits divided into groups, that is: X (1)=X (2)=10.
As an instantiation, can divide into groups to ascending control information in the following manner:
When in ascending control information, comprising dissimilar control informations, can divide into groups, that is: can dissimilar ascending control informations be distributed in the different ascending control information groupings according to the type of ascending control information.Because the receptivity that dissimilar ascending control informations requires is incomplete same, after dividing into groups according to the type of ascending control information, can encode separately, to improve the receptivity of receiving terminal to ascending control information to each grouping.For example: can the CQI in the ascending control information of A bit be distributed in the ascending control information grouping, response message is distributed in another ascending control information grouping; Perhaps, the SRI information distribution in the ascending control information of A bit in an ascending control information divides into groups, is distributed in response message in another ascending control information grouping; Perhaps, the CQI in the ascending control information of A bit is distributed in during ascending control information divides into groups, with the SRI information distribution in another ascending control information divides into groups.Specifically for instance; If comprise the CQI of 10 bits and the response message of 6 bits in the ascending control information of 16 bits; Then can the CQI of 10 bits be distributed as an ascending control information and divide into groups, the response message of 6 bits is divided into groups as another ascending control information.
As another instantiation, can also divide into groups to ascending control information in the following manner:
When in ascending control information, comprising the CQI of a plurality of carrier waves, can divide into groups to ascending control information, that is: can the CQI of different carrier be distributed in the different ascending control information groupings according to carrier wave.For example: if comprise the CQI of second carrier wave of the CQI of first carrier wave of 11 bits, 6 bits in the ascending control information of 17 bits; Then can the CQI of 11 bits of first carrier be distributed in during an ascending control information divides into groups, the CQI of 6 bits of second carrier wave is distributed in during another ascending control information divides into groups.
As another instantiation, can also divide into groups to ascending control information in the following manner:
When comprising CQI, response message and SRI information in the ascending control information of A bit, can be in an ascending control information divide into groups with response message and SRI information distribution, CQI is distributed in during another ascending control information divides into groups; Perhaps, CQI and SRI information distribution in an ascending control information divides into groups, are distributed in response message during another ascending control information divides into groups.For example; The SRI information that comprises response message and 1 bit of the CQI of 11 bits, 6 bits in the ascending control information of 18 bits; Then can the CQI of 11 bits be distributed in during ascending control information divides into groups, with the SRI information distribution of the response message of 6 bits and 1 bit in another ascending control information grouping.
Step 902 adopts first coding method and second coding method respectively, and to X (1), the ascending control information of the individual bit of X (2) divides into groups to encode, and generates 24 code word bits sequences.
Concrete, first coding method can be identical with second coding method, also can be different.
The Reed-Muller sign indicating number coding that concrete coding method can be based on Randt's Miller (Reed-Muller) sign indicating number or block also can be based on convolution coding, can also adopt other coding method.For example:, can be that (20, A) the Reed-Muller sign indicating number is encoded into 20 code word bits earlier, and then 20 code word bits are repeated into 24 bits for code book according to the LTE standard definition based on the coding method of Reed-Muller sign indicating number; Also can be according to the LTE standard definition code book (32, O) the Reed-Muller sign indicating number earlier coding generate 32 code word bits, and then 32 code word bits are blocked into 24 bits.Concrete, convolution code can be among the LTE convolution code.
Step 903,24 code word bits sequences of respectively ascending control information of X (1), the individual bit of X (2) being divided into groups to generate are carried out the QPSK modulation, obtain two groups of QPSK modulation symbols, and every group of QPSK modulation symbol comprises 12 modulation symbols.12 modulation symbols of the generation of the code word bits sequence that the ascending control information grouping of the individual bit of note X (1) generates are [q (0); Q (1) ..., q (11)]; 12 modulation symbols of the generation of the code word bits sequence that the ascending control information grouping of the individual bit of X (1) generates are [q (12); Q (13) ..., q (23)].
Step 904,12 modulation symbols that will obtain by the ascending control information of the individual bit of X (1) [q (0), q (1) ..., q (11)] be divided into two groups, every group comprises 6 modulation symbols; 12 modulation symbols that will obtain by the ascending control information of the individual bit of X (2) [q (12), q (13) ..., q (23)] be divided into two groups, every group comprises 6 modulation symbols.
Specifically, can with [q (0), q (1) ..., q (11)] be divided into two groups: [q (0), q (1) ..., q (5)] with [q (6), q (7) ..., q (11)]; Can with [q (12), q (13) ..., q (23)] be divided into two groups: [q (12), q (12) ..., q (17)] and [q (18), q (19) ..., q (23)].
Step 905, the two group's modulation symbols that respectively ascending control information with the individual bit of X (1) obtained are 6 DFT, obtain other two groups of data symbols [Q (0), Q (1) ..., Q (5)] with [Q (6), Q (7) ..., Q (11)]; The two group's modulation symbols that respectively ascending control information of the individual bit of X (2) obtained are 6 DFT, obtain other two groups of data symbols [Q (12), Q (13) ..., Q (17)] with [Q (18), Q (19) ..., Q (23)].
Step 906, two groups of data symbols [Q (0), the Q (1) that will obtain through step 905; ...; Q (5)] with [Q (6), Q (7) ...; Q (11)] in one group of the 0th slot s lot that is mapped to the DFT-S-OFDM form 0 send, the 1st the slot s lot 1 that another group is mapped to the DFT-S-OFDM form sends; To obtain two groups of data symbols [Q (12) through step 905; Q (13) ..., Q (17)] and [Q (18); Q (19); ..., Q (23)] in wherein one group of the 0th slot s lot that is mapped to the DFT-S-OFDM form 0 send, the 1st the slot s lot 1 that another group is mapped to the DFT-S-OFDM form sends.
Because each time slot forms a subchannel; Two groups of data symbols that two ascending control information block encodings are obtained are distributed on two time slots and transmit; With two groups of data symbols are distributed on the same time slot transmission and compare; Reduce same channel quality quality influence to same ascending control information block encoding piece when relatively poor, effectively guaranteed ascending control information block encoding piece quality balance.
