Description

A kind of method of definite repeated link HARQ sequential relationship

Technical field

The present invention relates to wireless communication technology, particularly a kind of definite repeated link mixes the method for automatic repeat requests (HARQ) sequential relationship.

Background technology

LTE/LTE-A one has 2 class frame structures, is suitable for FDD and TDD respectively.For FDD, the length of every frame is 10ms, comprises 10 subframes, is labeled as subframe 0 to 9 respectively, each subframe 1ms.For TDD, the length of every frame also is 10ms, also comprises 10 subframes, is labeled as subframe 0 to 9 respectively, and each subframe 1ms comprises sub-frame of uplink, descending sub frame and special subframe.At different up-downgoing business demands, TDD one has 7 kinds of configurations, and is specifically as shown in table 1:

Table 1

Wherein, in above-mentioned table 1, D represents descending sub frame, and U represents sub-frame of uplink, and S represents special subframe.

In LTE/LTE-A, downlink transfer is meant from the base station (eNB) signal transmission to subscriber equipment (UE), and at this moment, this signal is designated as downstream signal, specifically comprises downlink data signal, control signal and reference signal (being also referred to as pilot tone).Wherein, downlink data signal is transmission in Physical Downlink Shared Channel (PDSCH).Uplink is meant from UE to the signal of base station to be transmitted, and this moment, this signal can be designated as upward signal, specifically comprised upstream data. signals, control signal and reference signal (being also referred to as pilot signal).Wherein, upstream data. signals is transmission in the capable physically shared channel (PUSCH).Uplink control signal comprises, the ACK/ACK signal (HARQ-ACK) of the HARQ transmission of PDSCH, channel quality indication (CQI) signal and dispatch request indication (SRI) signal.Need to prove, if there is no upstream data. signals, then transmission in the capable physically control channel (PUCCH) of uplink control signal.

Usually, downgoing control signal can or send to special user equipment by broadcast transmission.Wherein, broadcast transmission is to send to all subscriber equipmenies by for example broadcast channel (BCH) or Physical Control Format Indicator Channel (PCFICH).And at the downgoing control signal that sends to special user equipment, it provides the descending scheduling assignment signalling of scheduling PDSCH transmission and the uplink scheduling assignment signalling of scheduling PUSCH transmission, is referred to as Physical Downlink Control Channel (PDCCH); The ACK/NACK information of the HARQ transmission of PUSCH perhaps is provided, is called Physical HARQ Indicator Channel (PHICH).

When carrying out transfer of data based on HARQ, according to whether data are correctly received, the data receiver is transferring ACK or NACK feedback information correspondingly.Here, be to finish to the scheduling of transfer of data by PDCCH, wherein, the ACK/NACK feedback signal of the HARQ of PDSCH transmission is in the PUCCHHARQ-ACK channel, the ACK/NACK feedback signal of the HARQ of PUSCH transmission is in the PHICH channel.

Usually, there is processing delay in HARQ, promptly, after UE receives PDSCH, postponing a period of time sends corresponding ACK/NACK information again, and also will postpone a period of time after eNB sends to its uplink data scheduling and send PUSCH again receiving, and correspondingly, after receiving PUSCH, eNB also to postpone a period of time to send ACK/NACK information to UE.Therefore, the transmission of HARQ needs the certain time sequence relation, and concrete HARQ sequential comprises: the sequential between sequential between the sequential between uplink data scheduling (UL grant) and the PUSCH, PUSCH and its corresponding ACK/NACK and PDSCH and its corresponding ACK/NACK.

The HARQ sequential relationship is among the current LTE:

(1) UE detects the UL grant that sends to oneself at subframe n, just the corresponding PUSCH of transmission in subframe n+K.For FDD, K=4, for TDD, concrete K value sees Table 2;

Table 2

(2), send corresponding ACK/NACK information at the PHICH of subframe n+K channel if eNB receives PUSCH in subframe n.For FDD, K=4, for TDD, concrete K value sees Table 3;

Table 3

(3) UE receives PDSCH in subframe n-K, sends corresponding ACK/NACK in subframe n.For FDD, K=4, for TDD, concrete K value sees Table 4.

Table 4

So far, finished description to current HARQ sequential.

In LTE-A, relaying (Relay) is one of key technology, and it can improve network capacity and improve the cell edge covering.Wherein, Relay is used for simultaneously the signal recompile modulation that receives from UE being sent to the base station receiving from sending to UE after the modulation of signal of base station recompile, covers thereby improved capacity or improved.Usually, Relay comprises 2 class links, and a class is a repeated link, and a class is an access link.Wherein, repeated link is the link between base station and the Relay, and access link is to connect the road between Relay and the UE.Here, repeated link is the same with access link, also divide uplink and downlink, usually will be defined as relaying Physical Downlink Shared Channel (R-PDSCH) at the Physical Downlink Shared Channel of repeated link transmission, and be defined as the up shared physical channel of relaying (R-PUSCH) at the up shared physical channel of repeated link transmission.Current, LTE-A reaches common understanding about Relay, for fear of the interference of repeated link and access link, repeated link and access link adopt time division multiplexing mode, promptly in the frame, some subframe is as the repeated link subframe, and some subframe is as the access link subframe.The base station should be some sub-frame allocation in the some cycles relay sub-frame, and this cycle can be 10ms.Here, the base station has dual mode that the repeated link subframe is notified to Relay, and a kind of is explicit way, and a kind of is the implicit expression mode.In explicit way, the base station can all be notified to Relay to relay uplink subframe and downlink relay link subframe with signaling method; In the implicit expression advice method, the base station only is notified to Relay to the downlink relay link subframe, and Relay determines the relay uplink subframe by the HARQ sequential relationship.For adopting which kind of advice method, current 3GPP reaches common understanding for LTE-A TDD, promptly adopts the explicit notification mode, but for FDD, still discussing, does not also reach common understanding at present.

The sequential relationship of described current HARQ is also referred to as LTE Rel-8, and (R8: version 8) sequential relationship is an access link, also determines at present the HARQ sequential relationship of the repeated link of the Relay correspondence introduced.And if repeated link HARQ adopts current LTE Rel-8 sequential relationship, this can make the efficient of repeated link and access link all low for the TDD system.

Embodiment

Method provided by the invention is primarily aimed at third generation partner and plans long-run development enhancing (3GPPLTE-A) system, and as a kind of expansion of the present invention, this method also can be generalized in other systems that adopt Relay.In order to make the purpose, technical solutions and advantages of the present invention clearer, describe the present invention below in conjunction with the drawings and specific embodiments.

Referring to Fig. 1, the basic flow sheet that Fig. 1 provides for the embodiment of the invention.As shown in Figure 1, this flow process can may further comprise the steps:

Step 101, trunking receive and are assigned with uplink relay subframe and downlink relay sub-frame.

Here, distribute uplink relay subframe and downlink relay sub-frame by donor base station (Donor eNB) for trunking in the step 101.Afterwards, donor base station is notified to trunking with the up-downgoing relay sub-frame of distributing.Here, the mode that donor base station is notified to trunking can have multiple implementation when specific implementation, such as, donor base station utilizes Radio Resource control (RRC) signaling that the numbering of backhaul configuration is notified to trunking, so, to receive the configuration of searching this numbering correspondence after the numbering of backhaul configuration in the configure table be the up-downgoing relay sub-frame to trunking; Perhaps donor base station utilizes the RRC signaling to adopt bit mapping mode to be notified to trunking, owing to comprise 10 subframes in each frame, here, can adopt 10 bit form, if the value of a bit is 1, the subframe of then representing this bit correspondence is as relay sub-frame, if promptly the subframe of this bit correspondence is a sub-frame of uplink, then this subframe can be used as uplink relay subframe; Equally, if the subframe of this bit correspondence is a descending sub frame, then this subframe can be used as downlink relay sub-frame.If the value of this bit is 0, represent that then this subframe can not be as relay sub-frame.

So, by top description, trunking is easy to the up-downgoing relay sub-frame of knowing that it is assigned with.Below donor base station is determined that the method for relay sub-frame is described.

Usually, in the TDD system, the subframe 0,1,5 and 6 in every frame is fixed for transmitting synchronous or broadcast message, and based on this, the downlink relay sub-frame that step 101 is known among the application does not comprise subframe 0,1,5 and 6.

Trunking is a half-duplex operation, promptly when relaying equipment when uplink relay subframe sends relay data to the base station, trunking just can not receive any data of terminal in this uplink relay subframe transmission.That is to say, if certain sub-frame of uplink is configured to uplink relay subframe, then terminal can not successfully be received by trunking at the ACK/NACK that this uplink relay subframe sends, so, the ACK/NACK of this subframe transmission causes and can't successfully transmit because of can not get the ACK/NACK feedback according to the PDSCH of the descending sub frame transmission of LTE Rel-8 HAQR sequential relationship correspondence.

Based on this, donor base station can be that trunking is determined uplink relay subframe and downlink relay sub-frame according to following principle in this step 101:

(1) according to the sequential relationship of LTE Rel-8 PDSCH and ACK/NACK, if all descending sub frames of sub-frame of uplink correspondence all are in subframe 0,1,5 and 6 at least one, then this sub-frame of uplink is not configured to uplink relay subframe.

(2) according to the sequential relationship of LTE Rel-8 PDSCH and ACK/NACK, if i.e. majority over half is in subframe 0,1,5 or 6 at least one in all descending sub frames of sub-frame of uplink correspondence, then this sub-frame of uplink is not configured to uplink relay subframe.

(3) according to the sequential relationship of LTE Rel-8 PDSCH and ACK/NACK, if non-majority is a subframe 0 in all descending sub frames of sub-frame of uplink correspondence, 1, in 5 and 6 at least one, then this sub-frame of uplink can be configured to uplink relay subframe, correspondingly, remove subframe 0 in the descending sub frame of this sub-frame of uplink correspondence, 1, descending sub frame outside 5 and 6 all can be configured to downlink relay sub-frame, a kind of expansion as the embodiment of the invention, remove subframe 0 in the descending sub frame of the non-correspondence of this sub-frame of uplink, 1, descending sub frame outside 5 and 6 also can be configured to downlink relay sub-frame, so that support higher down load.

(4) according to the sequential relationship of LTE Rel-8 PDSCH and ACK/NACK, if all descending sub frames of sub-frame of uplink correspondence do not comprise subframe 0,1,5 or 6, then this sub-frame of uplink can be configured to uplink relay subframe, correspondingly, the descending sub frame corresponding with this sub-frame of uplink also can be configured to downlink relay sub-frame, a kind of expansion as the embodiment of the invention, descending sub frame in the descending sub frame of the non-correspondence of this sub-frame of uplink except that subframe 0,1,5 and 6 also can be configured to downlink relay sub-frame, so that support higher down load.

So, be that trunking distributes uplink relay subframe and downlink relay sub-frame based on above-mentioned four principle donor base stations.

Step 102, trunking utilize described uplink relay subframe and downlink relay sub-frame to determine the HARQ sequential relationship.

Need to prove that as a kind of expansion of the embodiment of the invention, the present invention also provides another embodiment, specifically as shown in Figure 2, this method may further comprise the steps:

Step 201 is similar with above-mentioned steps 101, repeats no more here.

Step 202, trunking receives the RRC signaling; Here, carry the HARQ sequential relationship in the described RRC signaling.

Here, carried the HARQ sequential relationship of configuration in the RRC signaling, be specially: the sequential relationship between the corresponding ACK/NACK of R-PDSCH, and/or the sequential relationship between R-UL grant and the R-PUSCH with it.

Step 203, trunking utilize described uplink relay subframe and downlink relay sub-frame to determine the HARQ sequential relationship.

The HARQ sequential relationship of determining in above-mentioned steps 102 or the step 203 comprises: the sequential relationship (being designated as situation 1) between the corresponding ACK/NACK with it of R-PDSCH, and/or the sequential relationship between R-UL grant and the R-PUSCH (being designated as situation 2).

Wherein, at situation 1, then step 102 or step 203 are specially: if donor base station is given trunking at certain downlink relay sub-frame transmission R-PDSCH (being designated as downlink data), then if there is corresponding uplink relay subframe in this downlink relay sub-frame in LTE Rel-8 PDSCH and ACK/NACK sequential relationship, this trunking transferring ACK/nack message in the sub-frame of uplink of correspondence then, if there is no Dui Ying sub-frame of uplink, then first uplink relay subframe behind this downlink relay sub-frame 4ms is to described donor base station transferring ACK/nack message.

At situation 2, then step 102 or step 203 are specially: if donor base station is at certain downlink relay sub-frame transmission R-UL grant, then R-UL grant can dispatch unique uplink relay subframe transmission R-PUSCH (being designated as above-mentioned data) and give donor base station, is specially K the subframe of trunking after receiving described R-ULgrant and sends R-PUSCH to described donor base station.

Below by specific embodiment above-mentioned situation 1 and situation 2 are described.

Embodiment one:

This embodiment is primarily aimed at and is numbered the configuration of 2 ascending-descending subframes in the table 1 and is designated as TDD uplink-downlink configuration 2.Fig. 3 is the LTE Rel-8 HARQ sequential relationship schematic diagram of TDD uplink-downlink configuration 2.As shown in Figure 3, the upper part of Fig. 3 is the sequential relationship of PDSCH and ACK/NACK, and lower part is the sequential relationship of UL grant and PUSCH.As can be seen from Figure 3, for TDD uplink-downlink configuration 2, every frame has only 2 sub-frame of uplink, promptly is respectively subframe 2 and subframe 7.According to PDSCH shown in Fig. 3 upper part and the sequential relationship between the ACK/NACK, can know, the descending sub frame of subframe 2 correspondences is a subframe 4,5,6,8, as can be seen, only there is subframe 5 and 6 can not be configured to downlink relay sub-frame in all descending sub frames of this correspondence, but the ratio that subframe 5 and 6 accounts for not is over half, should be not most subframes 0 that are in all descending sub frames of correspondence promptly, 1, in 5 and 6 at least one, the 3rd principle in the corresponding mentioned above principle, therefore, can know, subframe 2 can be configured to uplink relay subframe, correspondingly, can know according to the 3rd principle, the subframe 4 of subframe 2 correspondences and 8 can be configured to downlink relay sub-frame, as a kind of expansion of the embodiment of the invention, can know that according to the 3rd principle the downlink relay sub-frame of subframe 2 non-correspondences is that subframe 3 and 9 also can be configured to downlink relay sub-frame, to support higher down load.

In like manner, for subframe 7, can know according to PDSCH shown in Fig. 3 upper part and the sequential relationship between the ACK/NACK, the descending sub frame of subframe 7 correspondences is a subframe 9,0,1 and 3, wherein, only there is subframe 0 and 1 can not be configured to downlink relay sub-frame in all descending sub frames of this correspondence, but the ratio that subframe 0 and 1 accounts for not is over half, should be not most subframes 0 that are in all descending sub frames of correspondence promptly, 1, in 5 and 6 at least one, the 3rd principle in the corresponding mentioned above principle, therefore, can know, subframe 7 can be configured to uplink relay subframe, correspondingly, can know according to the 3rd principle, the subframe 3 of subframe 7 correspondences and 9 can be configured to downlink relay sub-frame, as a kind of expansion of the embodiment of the invention, can know that according to the 3rd principle the descending sub frame of subframe 7 non-correspondences is that subframe 4 and 8 also can be configured to downlink relay sub-frame, to support higher down load.

More than the configuration of uplink relay subframe and downlink relay sub-frame in the TDD uplink-downlink configuration 2 is described.Easier to understand for the technical scheme that the application is provided, be for example to be described at 4: 1 at descending uplink relay subframe ratio in the TDD uplink-downlink configuration 2 below.Need to prove, should be for example just in order to make the application clearer, and non-limiting the application.

For descending uplink relay subframe ratio is 4: 1 o'clock, can select one of following 2 kinds of configurations.

First kind of configuration:

Can know that based on top description when this first kind configuration, donor base station is that the concrete ginseng of up-downgoing relay sub-frame that trunking distributes is shown in Table 5 to TDD uplink-downlink configuration 2.

Table 5

Wherein, D is a descending sub frame, and U is a sub-frame of uplink, here, the corresponding numbering 0 of backhaul configuration sign just in the described list item, it also can be 1 or other values, does not limit here.Understand easily in order to make the present techniques scheme, here be numbered 0 sign up-downgoing relay sub-frame configuration than 4: 1 with what backhaul was disposed, wherein, subframe 3,4,8,9 correspondence markings √ in the table 5 under the backhaul configuration 0, represent that then this subframe 3,4,8,9 is the up-downgoing relay sub-frame configuration than the downlink relay sub-frame under 4: 1 as this backhaul configuration 0, equally, subframe 2 correspondence markings √ represent that then this U is the up-downgoing relay sub-frame configuration than the uplink relay subframe under 4: 1 as this backhaul configuration 0.Below the analysis principle of each table similar, describe in detail no longer one by one.

Based on table 5, if adopt method shown in Figure 1, then donor base station is trunking allocation of downlink relay sub-frame and uplink relay subframe in step 101, and is specifically as shown in table 5, that is: subframe 2 is a uplink relay subframe, and subframe 3,4,8 and 9 is a downlink relay sub-frame.

So, when relaying equipment receives R-UL grant at subframe n, it sends R-PUSCH on subframe n+K.Here according to shown in the table 5 as can be seen, subframe 3,4,8,9 is a downlink relay sub-frame, therefore, trunking can only receive R-UL grant on subframe 3,4,8,9, because uplink relay subframe is a subframe 2, consider that based on time-delay is minimum can limit subframe n here is subframe 8, promptly trunking can only receive R-UL grant in subframe 8; Afterwards, trunking sends R-PUSCH on subframe n+K, here this K value must satisfy trunking and finally sends R-PUSCH on subframe 2, based on this, as a kind of embodiment of the present invention, here limiting this K value is 4, and promptly trunking will certainly send R-PUSCH on subframe 8+4 is the subframe 2 of next frame, specifically sees the following form 6.

Table 6

If on subframe n-K, receive R-PDSCH and work as relaying equipment, then trunking sends corresponding ACK/NACK at subframe n, here, according to shown in the table 5 as can be seen, uplink relay subframe is a subframe 2, and promptly trunking can only send corresponding ACK/NACK on subframe 2.Because subframe 3,4,8,9 is a downlink relay sub-frame, therefore, the K value of subframe 2 correspondences should satisfy trunking and receive R-PDSCH on subframe 3,4,8 or 9.Based on this, as a kind of embodiment of the present invention, limiting this K value here is 13,9,8,4, specifically sees the following form shown in 7.

Table 7

Need to prove that in method shown in Figure 1, donor base station only distributes up-downgoing relay sub-frame as shown in table 5 for trunking in the step 101; As for table 6 and table 7, determine the HARQ sequential relationship for ease of trunking, then above-mentioned table 6 and 7 is write standard, like this, when relaying equipment receives R-PDSCH or R-ULgrant can send corresponding ACK/NACK or R-PUSCH according to the standard of correspondence.

And if adopt method shown in Figure 2, then in step 201, donor base station is that trunking distributes downlink relay sub-frame and uplink relay subframe as shown in table 5, afterwards, donor base station sends the RRC signaling of having carried to the HARQ sequential relationship of trunking configuration in step 202, wherein, this HARQ sequential relationship can be configured according to the sequential relationship that table 6 and table 7 provide, specifically comprise: the sequential relationship of the sequential relationship of R-UL grant and R-PUSCH and R-PDSCH and its corresponding ACK/NACK, here, the sequential relationship of the sequential relationship of this R-UL grant and R-PUSCH and R-PDSCH and its corresponding ACK/NACK can be respectively shown in table 6 and 7, perhaps the sequential relationship of determining according to table 6 and table 7.So, when the subframe of relaying equipment, on the subframe that the HARQ timing relationship specified according to the RRC signaling determined, send the corresponding ACK/NACK of R-PDSCH that is received to donor base station at the R-PDSCH that receives; And when relaying equipment when receiving the subframe of R-UL grant, on the subframe that the HARQ timing relationship specified according to RRC instruction determined, send R-PUSCH to donor base station.

So far, having finished descending uplink relay subframe ratio is the description of first kind of configuration in 4: 1 o'clock.Below to descending uplink relay subframe ratio be 4: 1 o'clock second kind be configured into line description.

Second kind of configuration

Can know that based on top description donor base station is that the concrete ginseng of up-downgoing relay sub-frame that trunking distributes is shown in Table 8 to TDD uplink-downlink configuration 2.Be that subframe 7 is uplink relay subframe, subframe 3,4,8 and 9 is a downlink relay sub-frame.

Table 8

Based on table 8, if adopt method shown in Figure 1, then donor base station is trunking allocation of downlink relay sub-frame and uplink relay subframe in step 101, and is specifically as shown in table 8, that is: subframe 7 is a uplink relay subframe, and subframe 3,4,8 and 9 is a downlink relay sub-frame.

When relaying equipment receives R-UL grant at subframe n, it sends R-PUSCH on subframe n+K.Here as can be seen according to table 8, subframe 3,4,8,9 is a downlink relay sub-frame, therefore, trunking can only receive R-UL grant on subframe 3,4,8,9, because uplink relay subframe is a subframe 7, based on reduce HARQ sequential influence between trunking and subscriber equipment as far as possible, can limit subframe n here is subframe 3, and promptly trunking can only receive R-UL grant in subframe 3; Afterwards, trunking sends R-PUSCH on subframe n+K, sees the following form from following table 9 and finds out, when relaying equipment receives R-UL grant on subframe 3, this moment, the K value of subframe 3 correspondences was 4, and promptly trunking will certainly be to send R-PUSCH on the subframe 7 at subframe 3+4.

Table 9

If on subframe n-K, receive R-PDSCH and work as relaying equipment, then trunking sends corresponding ACK/NACK at subframe n, here, according to shown in the table 8 as can be seen, uplink relay subframe is a subframe 7, and promptly trunking can only send corresponding ACK/NACK on subframe 7.Because subframe 3,4,8,9 is a downlink relay sub-frame, therefore, the K value of subframe 7 correspondences should satisfy trunking and receive R-PDSCH on subframe 3,4,8 or 9.Based on this, can know that the K value of subframe 7 correspondences is 13,9,8,4, specifically sees the following form shown in 10.Table 10

And if adopt method shown in Figure 2, then in step 201, donor base station is that trunking distributes downlink relay sub-frame and uplink relay subframe as shown in table 8, promptly subframe 7 is a uplink relay subframe, subframe 3,4,8 and 9 is a downlink relay sub-frame.

Afterwards, in step 202, donor base station sends the RRC signaling of having carried to the HARQ sequential relationship of trunking configuration, wherein, this HARQ sequential relationship can be configured according to the sequential relationship that table 9 and table 10 provide, specifically comprise: the sequential relationship of the sequential relationship of R-UL grant and R-PUSCH and R-PDSCH and its corresponding ACK/NACK, here, the sequential relationship of the sequential relationship of this R-UL grant and R-PUSCH and R-PDSCH and its corresponding ACK/NACK can be respectively shown in table 9 and 10, perhaps the sequential relationship of determining according to table 9 and table 10.So, when the subframe of relaying equipment, on the subframe that the HARQ timing relationship specified according to the RRC signaling determined, send the corresponding ACK/NACK of R-PDSCH that is received to donor base station at the R-PDSCH that receives; And when relaying equipment when receiving the subframe of R-UL grant, on the subframe that the HARQ timing relationship specified according to RRC instruction determined, send R-PUSCH to donor base station.

Based on above-mentioned be the description of 4: 1 o'clock configuration to descending uplink relay subframe ratio, in order to improve the flexibility ratio of donor base station configuration relay station up-downgoing transmission time slot, to support the traffic load of relay station up-downgoing more flexibly ratio, the embodiment of the invention has further proposed the uplink-downlink configuration and the combination of HARQ sequential relationship of 2 times trunkings of TDD uplink-downlink configuration.Specifically see table shown in 11.

Table 11

Based on table 11, if adopt method shown in Figure 1, then donor base station is trunking allocation of downlink relay sub-frame and uplink relay subframe in step 101, and is specifically as shown in table 11.Wherein, backhaul configuration numbering and descending uplink relay subframe have any corresponding relation in the table 11, just 1: 1 o'clock ascending-descending subframes configuration in the above-mentioned table 11 with backhaul configuration 0 corresponding descending uplink relay subframe ratio, it is 2: 1 o'clock ascending-descending subframes configuration that 1 corresponding descending uplink relay subframe ratio is disposed in backhaul, it is 3: 1 o'clock ascending-descending subframes configuration that 2 corresponding descending uplink relay subframe ratios are disposed in backhaul, and backhaul to dispose 4 corresponding descending uplink relay subframe ratios be that 4: 1 o'clock ascending-descending subframes is configured to example and is described.That is to say that above-mentioned backhaul configuration is numbered setting, it is a sequence number, and unactual implication can not be provided with different backhaul configuration numberings according to actual conditions fully when practical application.Such as, also replaceablely in the above-mentioned table 11 be: it is 1: 1 o'clock ascending-descending subframes configuration that the backhaul configuration is numbered 1 corresponding descending uplink relay subframe ratio, it is 2: 1 o'clock ascending-descending subframes configuration that 0 corresponding descending uplink relay subframe ratio is disposed in backhaul, it is 3: 1 o'clock ascending-descending subframes configuration that 3 corresponding descending uplink relay subframe ratios are disposed in backhaul, and backhaul to dispose 2 corresponding descending uplink relay subframe ratios be 4: 1 o'clock ascending-descending subframes configuration etc.Be that example is described with above-mentioned table 11 below.Need to prove that the numbering of backhaul configuration and the configuration of up-downgoing relay sub-frame also have corresponding relation arbitrarily in follow-up each table, specifically as described above, describe in detail no longer one by one below.

So can obtain according to table 11: backhaul configuration 0 is that descending uplink relay subframe ratio is 1: 1 o'clock, subframe 2 is a uplink relay subframe, subframe 8 is a downlink relay sub-frame, backhaul configuration 1 is that descending uplink relay subframe ratio is 2: 1 o'clock, subframe 2 is a uplink relay subframe, and subframe 4 and subframe 8 are downlink relay sub-frame, and backhaul configuration 2 is that descending uplink relay subframe ratio is 3: 1 o'clock, subframe 2 is a uplink relay subframe, and subframe 4,8 and 9 is a downlink relay sub-frame; Backhaul configuration 3 is that descending uplink relay subframe ratio is 4: 1 o'clock, and subframe 2 is a uplink relay subframe, and subframe 3,4,8 and 9 is a downlink relay sub-frame.Need to prove, be to be configured to example with first kind at 4: 1 o'clock be described at descending uplink relay subframe ratio here, and preferably, the embodiment of the invention can also second kind be configured to example, and principle is similar, repeats no more here.
