The invention provides a technical scheme for solving the problem that the trunk node feeds back the ACK/NACK information to the base station after the trunk node receives the data sent by the base station in the current LTE-A system.
Description
Technical field
The present invention relates to the communication technology, particularly a kind of feedback of ACK/NACK information, processing method and equipment.
Background technology
At LTE-A, (LTE is the abbreviation of Long Term Evolution, it is the evolution system of 3-G (Generation Three mobile communication system), LTE-Advanced system is the upgrading of LTE system) relaying (Relay) transmission plan in system studying with design process in, from the progress of current research and discussion, main design goal is the Relay of (In-band) in half-duplex and band.So-called half-duplex, the operation that Relay node can not be received simultaneously and send out in same frequency.In so-called band, i.e. transfer of data between eNB (evolution base station) and Relay, eNB and Macro UE (Macro UE, grand UE; UE:User Equipment, subscriber equipment) transfer of data between, Relay are used identical frequency resource (in relay system with the transfer of data between Relay UE (relaying UE), the UE directly being served by eNB is called Macro UE, and the UE directly being served by Relay is called Relay-UE).
In relay system, frame structure can be divided into following regional:
Descending access region (TX): eNB and RN (Relay Node, via node) send data to respectively Macro UE and Relay UE;
Down mixing region (RX): eNB sends data to RN and Macro UE;
Up access region (RX): Macro UE and Relay UE send data to respectively eNB and RN;
Up Mixed Zone (TX): Macro UE and RN send data to eNB.
In order to make Relay network (keep Relay UE and Macro UE to have identical frame structure by compatible Rel-8UE, just some subframe does not send or receives), adopted MBSFN (MBSFNMulticast Broadcast Single Frequency Network, Multicast Broadcast Single Frequency Network) mode of subframe realizes the transfer of data of repeated link, and this scheme is as follows:
In up Mixed Zone, when RN sends data to eNB, Relay UE mourns in silence, and does not transmit any upward signal; In down mixing region, when to be eNB send data to RN, the frame structure of Relay is configured to MBSFN subframe, there are 1 or 2 OFDM (Orthogonal Frequency DivisionMultiplex, OFDM) the descending control signaling region of symbol, the UE transmission descending control signaling for Relay to its service; Now Relay can not receive the signal that comes from base station, and Relay receives the repeated link data (at this moment Relay does not send data to the UE of its service) of sending base station after this.Fig. 1 is that MBSFN subframe is for the design diagram of Relay frame structure; As shown in the figure, Fig. 1 has provided the Relay transmission plan based on TDD (Time Division Duplex, time division duplex) frame structure.In down mixing region, base-station transmission to the repeated link data of Relay and control signal be multiplexing together with data area transmission by MBSFN subframe, i.e. hatched example areas shown in figure.In up Mixed Zone, Relay is transferred in the relay uplink data of base station or control signal latticed region shown in the figure and transmits.In figure, DwPTS is that descending pilot frequency time slot (Downlink Pilot Time Slot), GP are uplink pilot time slot (Uplink Pilot Time slot) for protecting interval (guard period) and UpPTS.
Concerning UE, RN is transparent, be that can not distinguish its downlink transfer receiving be from base station or RN to UE, when therefore RN sends downlink data and control signal to UE, use the structure identical with base station, as sent descending control signaling at PDCCH (physical downlinkcontrol channel, Physical Downlink Control Channel) in the front several OFDM symbols in subframe.For down mixing region, eNB will send data to RN and Macro UE on the one hand, and RN also can send descending control signaling to Relay UE on the other hand.Because Relay is half-duplex, so the control signal that sends to Relay of eNB and data and Relay need to adopt the mode of time-division to transmit to the control signal of Relay UE transmission, and Fig. 2 is descending sub frame schematic diagram in repeated link, as shown in Figure 2.ENB sends control signaling to Macro UE on PDCCH, eNB sends control signaling to RN on R-PDCCH, eNB is upper to RN transmission data at R-PDSCH (relay-Physical Downlink Shared Channel, the physical down link sharing channel of relaying).ENB sends packet TB (Transport Block, transmission block) to Relay, and Relay is after receiving this TB, to producing a corresponding ACK/NACK after each TB decoding
(confirmation/non-confirmation) feedback information, in order to represent whether this TB correctly receives.ENB is after receiving the ACK/NACK of relay feedback, and the TB that relay is not correctly received retransmits.
The deficiencies in the prior art are: in current LTE-A system, receive after the data of NB transmission at RN, do not provide in corresponding technical scheme and solve RN to NB feeding back ACK/NACK.

Step 301, RN receive the TB that NB sends;
Step 302, RN determine the ACK/NACK information that need feed back to NB according to the reception correctness of TB;
Step 303, RN send ACK/NACK information by ascending control channel to NB.
Based on same inventive concept, in the embodiment of the present invention, also provide a kind of processing method of ACK/NACK feedback information, the ACK/NACK information of sending to NB by ascending control channel for the treatment of RN.
Fig. 4 is the processing method implementing procedure schematic diagram of ACK/NACK feedback information, as shown in the figure, during processing, can comprise the steps:
Step 401, NB receive the ACK/NACK information that RN feeds back by ascending control channel;
Step 402, NB are according to feedback system identification ACK/NACK information;
The ACK/NACK information that step 403, basis identify is determined the TB that needs repeating transmission.
For ease of intactly understanding enforcement and the combination of two kinds of technical schemes, these two kinds of technical schemes will be described in explanation simultaneously below.
In the enforcement of step 303, RN can send ACK/NACK information to NB by the ascending control channel of system configuration; Or RN can send ACK/NACK information to NB by the ascending control channel of dynamic-configuration.
Below the concrete enforcement to these two kinds of modes is respectively described, wherein, first is that the ascending control channel by system configuration sends, and second portion is that the up channel by dynamic-configuration sends.
First
This embodiment is mainly: RN is used the ascending control channel of system configuration, to base-station transmission ACK/NACK feedback information.Wherein, the configuration information of up channel can pass through high-level signaling (as RRC signaling) notice to RN.
That is: RN sends ACK/NACK information by the ascending control channel of system configuration to NB; And the ascending control channel of system configuration to be system set in advance, after system configuration is determined, RN determines according to the high-level signaling receiving.
In enforcement, if base station sends N >=1 TB to RN in a descending sub frame, RN will be to the corresponding ACK/NACK of a base station feedback N TB in same sub-frame of uplink.
If ascending-descending subframes is asymmetric in system, descending sub frame quantity is more than sub-frame of uplink quantity, RN by same sub-frame of uplink to the corresponding A CK/NACK of TB institute in a plurality of descending sub frames of base station feedback.
RN can be used following scheme to base station feedback ACK/NACK:
One, RN merges the corresponding ACK/NACK of all TB; An ascending control channel that uses PUCCH (PhysicalUplink Control Channel, Physical Uplink Control Channel) format 1a/1b form that the information exchange after merging is crossed to system configuration sends to NB.
In concrete enforcement, system can give each RN configuration an ascending control channel, and RN merges N the corresponding ACK/NACK information of TB, obtain one/organize after compound feedback information, use PUCCH format 1a/1b form, at the ascending control channel of system configuration, transmit.
Wherein merge based on code word and carry out, to belonging to a plurality of TB of same code word, merge, merging can realize by the mode of " logic add ".During single codeword transmission, merge and obtain a composite information, use PUCCH format 1a to transmit; During two codeword transmission, merge and obtain one group of (two) composite information, use PUCCH format 1b to transmit.
Base station, according to the composite information receiving, just can judge whether to retransmit all TB of certain code word.
Accordingly, in step 402, when base station, determining feedback system is that ACK/NACK information is while using PUCCH format 1a/1b form feedback after merging, base station receives the ACK/NACK information merging in an ascending control channel, the ACK/NACK information that identification merges according to feedback information, and determine whether to retransmit all TB according to the ACK/NACK information merging.
In existing system, for two kinds of form PUCCH format 1a and the PUCCH format 1b of the ascending control channel of transferring ACK/NACK feedback.Two kinds of main differences of form are that format 1a can only carry 1 bit feedback, use BPSK (Binary Phase Shift Keying, binary phase shift keying) modulate, format 1b can carry 2 bit feedback, use QPSK (Quadrature Phase-ShiftKeying, quadriphase PSK) to modulate.In two kinds of forms, feedback information obtains a modulation symbol through modulation, modulation symbol is further carried out after the Base-Band Processing such as cyclically shifted sequences spread spectrum, scrambling, orthogonal sequence spread spectrum, uses the channel of appointment to send.
Two, RN carries out combined coding by ACK/NACK information corresponding to all TB, and an ascending control channel that uses PUCCHformat 2 forms that the information exchange after combined coding is crossed to system configuration sends to NB;
Or RN merges the corresponding ACK/NACK of all TB, an ascending control channel that uses PUCCH format 2 forms that the information exchange after merging is crossed to system configuration sends to NB.
In concrete enforcement, system can give each RN configuration an ascending control channel:
1, RN carries out combined coding by ACK/NACK information corresponding to all TB, and an ascending control channel that uses PUCCHformat 2 forms that the information exchange after combined coding is crossed to system configuration sends to NB, can be specifically:
RN carries out combined coding by N the corresponding ACK/NACK information of TB, and uses the form of PUCCHformat 2, in the ascending control channel of system configuration, transmits.
If UE does not receive certain TB, its corresponding feedback states is made as to NACK.
Base station end is after completing reception, decoding, and just can judge accurately which TB need to retransmit.
Accordingly, in step 402, when base station, determining feedback system is that ACK/NACK information is carried out combined coding while using PUCCH format 2 forms feedback, base station receives the ACK/NACK information of carrying out combined coding in an ascending control channel, after decoding, identify a plurality of ACK/NACK information, and determine that according to ACK/NACK information which TB needs to retransmit.
2, RN merges the corresponding ACK/NACK of all TB, and an ascending control channel that uses PUCCH format 2 forms that the information exchange after merging is crossed to system configuration sends to NB, can be specifically:
RN can merge N the corresponding ACK/NACK of TB, merging is carried out (Merge Scenarios can with reference to the description in described the first scheme above) based on code word, thereby obtain one/group composite information, re-use the form of PUCCH format 2, in the ascending control channel of system configuration, transmit.
Base station just can judge whether to retransmit all TB of certain code word according to the composite information receiving.
Accordingly, in step 402, when base station, determining feedback system is that ACK/NACK information is while using PUCCH format 1a/1b form feedback after merging, base station receives the ACK/NACK information merging in an ascending control channel, the ACK/NACK information that identification merges according to feedback information, and determine whether to retransmit all TB according to the ACK/NACK information merging.
Three, to system, distribute the enforcement of M >=1 ascending control channel to describe to each RN below.
1, the ascending control channel number in system configuration is M, and TB number is N, and during M >=N, when the ascending control channel of RN by system configuration sends ACK/NACK information to NB, can comprise:
A corresponding ascending control channel of TB, the state that RN forms according to N the corresponding ACK/NACK information of TB is selected n >=1 transmission channel from N respective channels, and definite Qn bit information to be feedback, and wherein Q is order of modulation;
After the modulation of Q bit feedback information, obtain a modulation symbol, use the defined baseband processing method except modulation of format 1a/1b form, respectively selected n channel Q bit information to be feedback.
In concrete enforcement, if M >=N, a corresponding ascending control channel of TB.RN, by the state forming according to N the corresponding ACK/NACK information of TB, selects n >=1 transmission channel from N respective channels, and definite Qn bit information to be feedback, and wherein Q is order of modulation, and Q bit information, after modulation, becomes a modulation symbol.
Then use the defined baseband processing method except modulation of format 1a/1b form, respectively selected n channel Q bit feedback information.
The Qn bit feedback information receiving in base station basis, and transmit after n the channel number of using, just can judge which TB needs to retransmit.
Accordingly, in step 402, when base station, determining feedback system is that ACK/NACK information is when transmitting Qn bit feedback information in selected channel, base station receives Qn bit feedback information in an ascending control channel, the channel number of using according to transmission and a plurality of ACK/NACK information of Qn bit feedback letter identification, and determine that according to a plurality of ACK/NACK information which TB needs to retransmit.
2, the ascending control channel number in system configuration is M, and TB number is N, and during M < N, and the ascending control channel of RN by system configuration sends ACK/NACK information to NB and can comprise:
N TB is divided into M group, and every group of corresponding ascending control channel, merges ACK/NACK corresponding to a plurality of TB in every group;
The state that ACK/NACK information after RN merges according to M forms is selected m >=1 from M respective channels, and definite Qm bit information to be feedback, and wherein Q is order of modulation;
After the information modulation to be feedback of Q bit, obtain a modulation symbol, use the defined baseband processing method except modulation of format 1a/1b form, respectively selected m channel Q bit information to be feedback.
Wherein, N TB is being divided into M when group, will taking the TB of identical running time-frequency resource or take same frequency resources but the adjacent TB of time domain is divided into one group.
In concrete enforcement, if M < is N, first N TB is divided into M group, every group of corresponding ascending control channel.While dividing into groups, can by take identical running time-frequency resource TB, take same frequency resources but the adjacent TB of time domain is divided into one group.
After grouping, ACK/NACK corresponding to a plurality of TB in every group merged to (Merge Scenarios can with reference to the description in described the first scheme above), obtain a compound feedback information.
The state that RN will form according to M (compound) ACK/NACK information is selected m >=1 from M respective channels, and definite Qm bit information to be feedback, and wherein Q is order of modulation, and Q bit information, after modulation, becomes a modulation symbol.Use the defined baseband processing method except modulation of format 1a/1b form, respectively selected m channel Q bit feedback information.
Base station is according to the Qm bit feedback information that receives, and m channel number using of transmission, just can judge where to organize TB and need re-transmission.
Accordingly, in step 402, when base station, determining feedback system is that ACK/NACK information is when transmitting Qn bit feedback information in selected channel, base station receives Qn bit feedback information in an ascending control channel, the channel number of using according to transmission and a plurality of ACK/NACK information of Qn bit feedback letter identification, and determine that according to a plurality of ACK/NACK information which TB needs to retransmit.
Four, the ascending control channel number in system configuration is M, and TB number is N, and M >=N >=1 o'clock, and RN sends ACK/NACK information by the ascending control channel of system configuration to NB, can comprise:
Each ascending control channel correspondence one or one group of TB, and RN is used PUCCH format 1a/1b form, transmits a plurality of simultaneously or organize the corresponding ACK/NACK information of TB more on a plurality of ascending control channels of system configuration.
In concrete enforcement, system distributes M >=1 ascending control channel can to each RN, and each ascending control channel correspondence one/group TB.
RN can be used PUCCH format 1a/1b form, on a plurality of ascending control channels of system configuration, transmits a plurality of/corresponding ACK/NACK information of group TB simultaneously.During single codeword transmission, use PUCCH format 1a; During two codeword transmission, use PUCCH format 1b.
When if former ACK/NACK/group number is greater than M, can be first part TB be wherein merged that (Merge Scenarios can be with reference to the description in described the first scheme above, combination principle can be referring to the description in third party's case below), make ACK/NACK to be feedback/group number be not more than M.
Base station according to receive a plurality of/group feedback information, just can judge respectively which TB need to retransmit.
Accordingly, in step 402, when base station, determining feedback system is that ACK/NACK information is by a plurality of/when feedback group, base station in a plurality of ascending control channels, receive simultaneously transmission a plurality of/group ACK/NACK information, according to the feedback information identification ACK/NACK information of a plurality of/group, and determine that according to ACK/NACK information which TB needs to retransmit.
Second portion
This embodiment is mainly: RN is used the ascending control channel of dynamic-configuration, to base-station transmission ACK/NACK, feeds back.Wherein, the up channel numbering that each RN is used, the CCE numbering that the descending control signaling that sends to RN according to NB is shared obtains.
That is: RN sends ACK/NACK information by the ascending control channel of dynamic-configuration to NB.When the ascending control channel at RN by dynamic-configuration sends ACK/NACK information to NB, the shared CCE numbering of descending control signaling that RN sends according to NB is determined the ascending control channel of described dynamic-configuration.
If base station sends N >=1 TB to RN in a descending sub frame, RN by a sub-frame of uplink of correspondence to the corresponding ACK/NACK of a base station feedback N TB.
If the ascending-descending subframes in system repeated link is asymmetric, descending sub frame quantity is more than sub-frame of uplink quantity, RN by a sub-frame of uplink of correspondence to base station feedback the corresponding A CK/NACK of the institute of the TB in a plurality of descending sub frames.
In enforcement, RN can be in the following ways to NB feeding back ACK/NACK: one, the ascending control channel of dynamic-configuration is the ascending control channel that RN and Macro UE share identical physical resource region; Two, the ascending control channel of dynamic-configuration is the ascending control channel that RN has special-purpose physical resource region.Describe below.
One, RN shares identical physical resource region with Macro UE.
This scheme is applicable to the sub-frame of uplink that RN data are carried out ACK/NACK feedback, the situation identical with the corresponding ACK/NACK feeding back uplink of the Macro UE data subframe of transmitting in same descending sub frame.When the shared CCE numbering of descending control signaling sending according to NB at RN is determined the ascending control channel of described dynamic-configuration, RN is by the numbering (n of the shared some CCE of descending control signaling
cCE) calculate ascending control channel numbering (n
aN), and determine according to the ascending control channel numbering calculating the physical resource position that sends ACK/NACK information.
From the angle of NB, RN can be regarded as to a special Macro UE, its main difference is that corresponding descending control signaling transmits on different physical resources.The shared CCE Unified number of all descending control signalings that NB is sent, RN is when carrying out uplink ACK/NACK feedback, use the method identical with Macro UE to determine the numbering of its ascending control channel, by the numbering (n of the shared some CCE of descending control signaling
cCE) calculating ascending control channel numbering (n
aN), n
aN=g (n
cCE)+N
aN, N wherein
aNfor high-rise configuration parameter, represent the original position in physical resource region, this function meets one-to-one relationship, i.e. different n
cCEafter mapping, can obtain different n
aN, and use the mode of PUCCH format 1/1a/1b to transmit.The ascending control channel that wherein RN and Macro UE are used by mixed distribution in PUCCHformat 1/1a/1b resource area.
And RN is by the numbering (n of the shared CCE of descending control signaling
cCE) calculate ascending control channel numbering (n
aN), can comprise one of following mode:
1, NB sends to the shared CCE of descending control signaling of RN, can be after NB sends to the shared CCE of the descending control signaling of MarcoUE Unified number.
If it is 0,1,2 that the CCE in PDCCH numbers in order, ..., n-1, wherein n is the quantity of CCE in PDCCH, the CCE in R-PDCCH numbers in order as n, n+1, n+2..., n+m-1, wherein m is the quantity of CCE in R-PDCCH, in system, reserved ascending control channel quantity will increase when without RN to some extent, is n+m.
2, RN determines that NB passes through the numbering (n of the shared CCE of the descending control signaling of scheduling reservation
cCE) calculate ascending control channel numbering (n
aN).
NB can limit in PDCCH by scheduling that m CCE is reserved not to be used, wherein m is the quantity that in R-PDCCH, NB sends to the shared CCE being numbered of the descending control signaling of RN, and the CCE that the numbering of m in PDCCH reserved CCE is distributed in R-PDCCH is used.
If total CCE quantity is n in PDCCH, and the CCE quantity of using in R-PDCCH is m, base station can be limited at least reserved m CCE in PDCCH by scheduling and do not used, and the CCE that the numbering of CCE in this m PDCCH is distributed in R-PDCCH is used, in system, reserved ascending control channel quantity is identical when without RN, for n, and can make g (n
cCE)=f (n
cCE).
3, RN is by the numbering (n of the shared CCE of descending control signaling corresponding to Broadcast Control Channel in PDCCH
cCE) calculate ascending control channel numbering (n
aN).
Because Broadcast Control Channel in system does not need HARQ (Hybrid Automatic RepeatRequest, mixed automatic repeat request) retransmit, therefore the ascending control channel that the shared CCE mapping of descending control signaling corresponding to Broadcast Control Channel obtains is always idle, if the special-purpose CCE numbering of descending control signaling corresponding to Broadcast Control Channel in PDCCH redistributed to the CCE numbering in R-PDCCH and used, in system, reserved ascending control channel quantity is identical when without RN, for n, and can make g (n
cCE)=f (n
cCE)
From ascending control channel, for one or more, real-time mode that sends ACK/NACK is described respectively below.
One) TB, sending at RN reception NB is a plurality of, when RN sends ACK/NACK information by an ascending control channel to NB, after RN merges the corresponding ACK/NACK information of a plurality of TB, use PUCCH format 1a/1b form to NB, to send ACK/NACK information by ascending control channel.
If NB sends a plurality of TB to RN, and RN has to a corresponding ascending control channel, after can first merging the corresponding ACK/NACK information of a plurality of TB, re-uses corresponding ascending control channel and transmits.
