Description

A kind of method determining sequential relationship of hybrid-automatic repeat request of relay link

Technical field

The present invention relates to wireless communication technology, particularly one determines the method for hybrid automatic retransmission request of relay link (HARQ) sequential relationship.

Background technology

LTE/LTE-A mono-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 is also 10ms, also comprises 10 subframes, is labeled as subframe 0 to 9 respectively, each subframe 1ms, comprise sub-frame of uplink, descending sub frame and special subframe.For different up-downgoing business demand, TDD mono-has 7 kinds of configurations, specifically as shown in table 1:

Table 1

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

In LTE/LTE-A, downlink transfer refers to the Signal transmissions from base station (eNB) to subscriber equipment (UE), now, this signal is designated as downstream signal, specifically comprises downlink data signal, control signal and reference signal (also referred to as pilot tone).Wherein, downlink data signal is transmission in Physical Downlink Shared Channel (PDSCH).Uplink refers to the Signal transmissions from UE to base station, and now this signal can be designated as upward signal, specifically comprises upstream data. signals, control signal and reference signal (also referred to as pilot signal).Wherein, upstream data. signals is the middle transmission of row shared channel (PUSCH) physically.Uplink control signal comprises, and the ACK/ACK signal (HARQ-ACK) of the HARQ transmission of PDSCH, channel quality indicate (CQI) signal and dispatch request instruction (SRI) signal.It should be noted that, if there is no upstream data. signals, then the uplink control signal middle transmission of row control channel (PUCCH) physically.

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

Whether, when carrying out transfer of data based on HARQ, correctly receive according to data, data receiver is transferring ACK or NACK feedback information correspondingly.Here, be completed by PDCCH to the scheduling of transfer of data, wherein, the ACK/NACK feedback signal of the HARQ transmission of PDSCH is in PUCCHHARQ-ACK channel, and the ACK/NACK feedback signal of the HARQ transmission of PUSCH is in PHICH channel.

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

In current LTE, HARQ sequential relationship is:

(1) UE detects the ULgrant sending to oneself at subframe n, just in subframe n+K, transmits corresponding PUSCH.For FDD, K=4, for TDD, concrete K value is in table 2;

Table 2

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

Table 4

So far, the description to current HARQ sequential is completed.

In LTE-A, relaying (Relay) is one of key technology, and it can improve network capacity and improve cell edge covering.Wherein, Relay, for sending to UE after the signal recompile modulation received from base station, sends to base station the signal recompile modulation received from UE simultaneously, thus improves capacity or improve covering.Usually, Relay comprises 2 class links, and a class is repeated link, and a class is access link.Wherein, repeated link is the link between base station and Relay, and access link is link between Relay and UE.Here, repeated link is the same with access link, also uplink and downlink are divided, usually the Physical Downlink Shared Channel transmitted at repeated link is defined as relaying Physical Downlink Shared Channel (R-PDSCH), and is defined as the up shared physical channel (R-PUSCH) of relaying at the up shared physical channel of repeated link transmission.Current, LTE-A reaches common understanding about Relay, in order to avoid the interference of repeated link and access link, repeated link and access link adopt time division multiplexing mode, namely, in a frame, some subframe is as repeated link subframe, and some subframe is as access link subframe.Base station should be relay sub-frame some sub-frame allocation in some cycles, and this cycle can be 10ms.Here, base station has two kinds of modes that repeated link subframe is informed Relay, and one is explicit way, and one is implicit.In explicit way, base station all can inform Relay relay uplink subframe and downlink relay link subframe with signaling method; In implicit expression advice method, base station only informs Relay downlink relay link subframe, and Relay is by HARQ sequential relationship determination relay uplink subframe.For which kind of advice method of employing, current 3GPP reaches common understanding for LTE-ATDD, namely adopts explicit notification mode, but for FDD, at present still in discussion, does not also reach common understanding.

The sequential relationship of described current HARQ is access link also referred to as LTERel-8 (R8: version 8) sequential relationship, does not also determine the HARQ sequential relationship of the repeated link that the Relay of introducing is corresponding at present.Further, if repeated link HARQ adopts current LTERel-8 sequential relationship, this is for TDD system, and the efficiency of repeated link and access link can be made all low.

Embodiment

Method provided by the invention strengthens (3GPPLTE-A) system mainly for the long-run development of third generation Partnership Program, and as one expansion of the present invention, the method also can be generalized to other and adopts in the system of Relay.In order to make the object, technical solutions and advantages of the present invention clearly, describe the present invention below in conjunction with the drawings and specific embodiments.

See the basic flow sheet that Fig. 1, Fig. 1 provide for the embodiment of the present invention.As shown in Figure 1, this flow process can comprise the following steps:

Step 101, trunking receives and is assigned with uplink relay subframe and downlink relay sub-frame.

Here, be that trunking distributes uplink relay subframe and downlink relay sub-frame by donor base station (DonoreNB) in step 101.Afterwards, the up-downgoing relay sub-frame of distribution is informed to trunking by donor base station.Here, the mode that donor base station informs trunking can have multiple implementation when specific implementation, such as, donor base station utilizes wireless heterogeneous networks (RRC) signaling that the numbering that backhaul configures is informed trunking, so, configuration and the up-downgoing relay sub-frame of this numbering correspondence is searched after trunking receives the numbering of backhaul configuration in configure table; Or donor base station utilizes RRC signaling to adopt bit mapping mode to inform trunking, owing to comprising 10 subframes in each frame, here, 10 bit form can be adopted, if the value of a bit is 1, then represent that subframe that this bit is corresponding is as relay sub-frame, if the subframe that namely this bit is corresponding is sub-frame of uplink, then this subframe can be used as uplink relay subframe; Equally, if subframe corresponding to this bit is descending sub frame, then this subframe can be used as downlink relay sub-frame.If the value of this bit is 0, then represent that this subframe can not as relay sub-frame.

So, by describing above, trunking is easy to the up-downgoing relay sub-frame knowing that it is assigned with.Below the method for donor base station determination relay sub-frame is described.

Usually, in a 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 in the application, step 101 is known does not comprise subframe 0,1,5 and 6.

Trunking is half-duplex operation, and namely when trunking sends relay data to base station in uplink relay subframe, trunking just can not receive any data that terminal sends in this uplink relay subframe.That is, if certain sub-frame of uplink is configured to uplink relay subframe, the ACK/NACK that then terminal sends in this uplink relay subframe successfully can not be received by trunking, so, because can not get ACK/NACK feedback, cause cannot Successful transmissions according to the PDSCH of descending sub frame transmission corresponding to LTERel-8HAQR sequential relationship for the ACK/NACK of this sub-frame transmission.

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

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

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

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

(4) according to the sequential relationship of LTERel-8PDSCH and ACK/NACK, if all descending sub frames that sub-frame of uplink is corresponding 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, one as the embodiment of the present invention is expanded, descending sub frame in the descending sub frame of this sub-frame of uplink non-corresponding except subframe 0,1,5 and 6 also can be configured to downlink relay sub-frame, to 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 utilizes described uplink relay subframe and downlink relay sub-frame to determine HARQ sequential relationship.

It should be noted that, the one as the embodiment of the present invention is expanded, and present invention also offers another embodiment, and specifically as shown in Figure 2, the method comprises the following steps:

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

Step 202, trunking receives RRC signaling; Here, HARQ sequential relationship is carried in described RRC signaling.

Here, carry the HARQ sequential relationship of configuration in RRC signaling, be specially: the sequential relationship between R-PDSCH ACK/NACK corresponding to it, and/or the sequential relationship between R-ULgrant and R-PUSCH.

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

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

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

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

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

Embodiment one:

This embodiment is designated as TDD uplink-downlink configuration 2 mainly for the ascending-descending subframes configuration being numbered 2 in table 1.Fig. 3 is the LTERel-8HARQ 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 ULgrant and PUSCH.As can be seen from Figure 3, for TDD uplink-downlink configuration 2, every frame only has 2 sub-frame of uplink, is namely respectively subframe 2 and subframe 7.Sequential relationship between PDSCH and ACK/NACK according to Fig. 3 upper part, can know, the descending sub frame of subframe 2 correspondence is subframe 4, 5, 6, 8, can find out, subframe 5 and 6 is only had not to 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 is not over half, in all descending sub frames of i.e. this correspondence, not majority is subframe 0, 1, at least one in 5 and 6, 3rd principle in 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 and 8 of subframe 2 correspondence can be configured to downlink relay sub-frame, one as the embodiment of the present invention is expanded, can know that the downlink relay sub-frame of subframe 2 non-corresponding and subframe 3 and 9 also can be configured to downlink relay sub-frame according to the 3rd principle, to support higher down load.

In like manner, for subframe 7, sequential relationship between PDSCH and ACK/NACK according to Fig. 3 upper part can be known, the descending sub frame of subframe 7 correspondence is subframe 9, 0, 1 and 3, wherein, subframe 0 and 1 is only had not to 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 is not over half, in all descending sub frames of i.e. this correspondence, not majority is subframe 0, 1, at least one in 5 and 6, 3rd principle in 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 and 9 of subframe 7 correspondence can be configured to downlink relay sub-frame, one as the embodiment of the present invention is expanded, can know that the descending sub frame of subframe 7 non-corresponding and subframe 4 and 8 also can be configured to downlink relay sub-frame according to the 3rd principle, to support higher down load.

Above the configuration of uplink relay subframe and downlink relay sub-frame in TDD uplink-downlink configuration 2 is described.The technical scheme provided to make the application is easier to understand, compares for 4:1 is that example is described below for uplink relay subframe descending in TDD uplink-downlink configuration 2.It should be noted that, this citing is just in order to make the application clearly, and non-limiting the application.

For descending uplink relay subframe than during for 4:1, one of following 2 kinds of configurations can be selected.

The first configuration:

Based on knowing the description of TDD uplink-downlink configuration 2 above, at this during the first configuration, donor base station is that the up-downgoing relay sub-frame that trunking distributes specifically is joined and is shown in Table 5.

Table 5

Wherein, D is descending sub frame, and U is sub-frame of uplink, and here, the numbering 0 that in described list item, backhaul configuration is corresponding is a mark, and it also can be 1 or other values, does not limit here.In order to make technical scheme easy understand, here 4:1 is compared with the 0 mark up-downgoing relay sub-frame configuration that is numbered of backhaul configuration, wherein, in table 5, backhaul configures subframe 3,4,8, the 9 correspondence markings √ under 0, then represent this subframe 3,4,8,9 as this backhaul configuration 0 i.e. up-downgoing relay sub-frame configuration than the downlink relay sub-frame under 4:1, equally, subframe 2 correspondence markings √, then represent this U as this backhaul configuration 0 i.e. up-downgoing relay sub-frame configuration than the uplink relay subframe under 4:1.The analysis principle of each table is similar below, describes in detail no longer one by one.

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

So, when trunking receives R-ULgrant at subframe n, it sends R-PUSCH on subframe n+K.Here can find out according to table 5 Suo Shi, subframe 3,4,8,9 is downlink relay sub-frame, therefore, trunking can only receive R-ULgrant in subframe 3,4,8,9, because uplink relay subframe is subframe 2, based on the minimum consideration of time delay, can limit subframe n is here subframe 8, and namely trunking can only receive R-ULgrant in subframe 8; Afterwards, trunking sends R-PUSCH on subframe n+K, here this K value must meet trunking and finally in subframe 2, sends R-PUSCH, based on this, as a kind of embodiment of the present invention, here limiting this K value is 4, and namely trunking will certainly send R-PUSCH in the subframe 2 of subframe 8+4 and next frame, specifically sees the following form 6.

Table 6

And if on subframe n-K, receive R-PDSCH when trunking, then trunking sends corresponding ACK/NACK at subframe n, here, can find out according to table 5 Suo Shi, uplink relay subframe is subframe 2, and namely trunking can only send corresponding ACK/NACK in subframe 2.Because subframe 3,4,8,9 is downlink relay sub-frame, therefore, the K value of subframe 2 correspondence should meet trunking receive R-PDSCH in subframe 3,4,8 or 9.Based on this, as a kind of embodiment of the present invention, limiting this K value is here 13,9,8,4, specifically sees the following form shown in 7.

Table 7

It should be noted that, in the method shown in Fig. 1, in step 101, donor base station is only for trunking distributes up-downgoing relay sub-frame as shown in table 5; As for table 6 and table 7, determine HARQ sequential relationship for ease of trunking, then by above-mentioned table 6 and 7 write specifications, like this, corresponding ACK/NACK or R-PUSCH can be sent according to the specification of correspondence when trunking receives R-PDSCH or R-ULgrant.

If and adopt the method shown in Fig. 2, then in step 201, donor base station is that trunking distributes downlink relay sub-frame as shown in table 5 and uplink relay subframe, afterwards, donor base station sends the RRC signaling of the HARQ sequential relationship carried as trunking configuration in step 202., wherein, the sequential relationship that this HARQ sequential relationship can provide according to table 6 and table 7 is configured, specifically comprise: the sequential relationship of the sequential relationship of R-ULgrant and R-PUSCH and R-PDSCH and its corresponding ACK/NACK, here, the sequential relationship of the sequential relationship of this R-ULgrant and R-PUSCH and R-PDSCH and its corresponding ACK/NACK can be respectively shown in table 6 and 7, or according to the sequential relationship that table 6 and table 7 are determined.So, when trunking is when the subframe of the R-PDSCH received, the subframe determined according to the HARQ timing relationship specified by RRC signaling sends to donor base station the corresponding ACK/NACK of R-PDSCH received; And when trunking is when receiving the subframe of R-ULgrant, the subframe determined according to the HARQ timing relationship specified by RRC instruction sends R-PUSCH to donor base station.

So far, complete descending uplink relay subframe than the description for the first configuration during 4:1.Below descending uplink relay subframe is described than for the second configuration during 4:1.

The second configures

Based on knowing the description of TDD uplink-downlink configuration 2 above, donor base station is that the up-downgoing relay sub-frame that trunking distributes specifically is joined and is shown in Table 8.Namely subframe 7 is uplink relay subframe, and subframe 3,4,8 and 9 is downlink relay sub-frame.

Table 8

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

When trunking receives R-ULgrant at subframe n, it sends R-PUSCH on subframe n+K.Here can find out according to table 8, subframe 3,4,8,9 is downlink relay sub-frame, therefore, trunking can only receive R-ULgrant in subframe 3,4,8,9, because uplink relay subframe is subframe 7, based on reducing HARQ sequential impact between trunking and subscriber equipment as far as possible, can limit subframe n is here subframe 3, and namely trunking can only receive R-ULgrant in subframe 3; Afterwards, trunking sends R-PUSCH on subframe n+K, sees the following form find out from following table 9, and when trunking receives R-ULgrant in subframe 3, now the K value of subframe 3 correspondence is 4, and namely trunking will certainly send R-PUSCH on subframe 3+4 and subframe 7.

Table 9

And if on subframe n-K, receive R-PDSCH when trunking, then trunking sends corresponding ACK/NACK at subframe n, here, can find out according to table 8 Suo Shi, uplink relay subframe is subframe 7, and namely trunking can only send corresponding ACK/NACK in subframe 7.Because subframe 3,4,8,9 is downlink relay sub-frame, therefore, the K value of subframe 7 correspondence should meet trunking receive R-PDSCH in subframe 3,4,8 or 9.Based on this, can know, the K value of subframe 7 correspondence is 13,9,8,4, specifically sees the following form shown in 10.

Table 10

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

Afterwards, in step 202., donor base station sends the RRC signaling of the HARQ sequential relationship carried as trunking configuration, wherein, the sequential relationship that this HARQ sequential relationship can provide according to table 9 and table 10 is configured, specifically comprise: the sequential relationship of the sequential relationship of R-ULgrant and R-PUSCH and R-PDSCH and its corresponding ACK/NACK, here, the sequential relationship of the sequential relationship of this R-ULgrant and R-PUSCH and R-PDSCH and its corresponding ACK/NACK can be respectively shown in table 9 and 10, or according to the sequential relationship that table 9 and table 10 are determined.So, when trunking is when the subframe of the R-PDSCH received, the subframe determined according to the HARQ timing relationship specified by RRC signaling sends to donor base station the corresponding ACK/NACK of R-PDSCH received; And when trunking is when receiving the subframe of R-ULgrant, the subframe determined according to the HARQ timing relationship specified by RRC instruction sends R-PUSCH to donor base station.

Based on above-mentioned to the description of descending uplink relay subframe than configuration when being 4:1, in order to improve the flexibility ratio of donor base station configuration relay station downstream transmission time slot, to support relay station downstream transmission load percentage more flexibly, the embodiment of the present invention further provides uplink-downlink configuration and the combination of HARQ sequential relationship of TDD uplink-downlink configuration 2 times trunkings.Specifically see table shown in 11.

Table 11

Based on table 11, if the method shown in Fig. 1 of employing, then donor base station is trunking allocation of downlink relay sub-frame and uplink relay subframe in a step 101, specifically as shown in table 11.Wherein, in table 11, backhaul configuration numbering and descending uplink relay subframe have any corresponding relation, just configure than for ascending-descending subframes during 1:1 with the corresponding descending uplink relay subframe of backhaul configuration 0 in above-mentioned table 11, backhaul configures 1 corresponding descending uplink relay subframe than being ascending-descending subframes configuration during 2:1, backhaul configures 2 corresponding descending uplink relay subframe than being ascending-descending subframes configuration during 3:1, and backhaul configures 4 corresponding descending uplink relay subframe and is described than for ascending-descending subframes during 4:1 is configured to example.That is, above-mentioned backhaul configuration is numbered setting, and it is a sequence number, unactual implication, can arrange different backhaul configuration numberings completely when practical application according to actual conditions.Such as, also can be replaced in above-mentioned table 11: backhaul configuration is numbered 1 corresponding descending uplink relay subframe than being ascending-descending subframes configuration during 1:1, backhaul configures 0 corresponding descending uplink relay subframe than being ascending-descending subframes configuration during 2:1, backhaul configures 3 corresponding descending uplink relay subframe than being ascending-descending subframes configuration during 3:1, and backhaul configures 2 corresponding descending uplink relay subframe than being the ascending-descending subframes configuration etc. during 4:1.Be described for above-mentioned table 11 below.It should be noted that, in follow-up each table, the numbering of backhaul configuration and the configuration of up-downgoing relay sub-frame also have arbitrary corresponding relation, specifically as described above, describe in detail no longer one by one below.

So can obtain according to table 11: backhaul configuration 0 i.e. descending uplink relay subframe is than during for 1:1, subframe 2 is uplink relay subframe, subframe 8 is downlink relay sub-frame, backhaul configuration 1 i.e. descending uplink relay subframe is than during for 2:1, subframe 2 is uplink relay subframe, and subframe 4 and subframe 8 are downlink relay sub-frame, and backhaul configuration 2 i.e. descending uplink relay subframe is than during for 3:1, subframe 2 is uplink relay subframe, and subframe 4,8 and 9 is downlink relay sub-frame; Backhaul configuration 3 i.e. descending uplink relay subframe is than during for 4:1, and subframe 2 is uplink relay subframe, and subframe 3,4,8 and 9 is downlink relay sub-frame.It should be noted that, here in descending uplink relay subframe than in order to be configured to the first during 4:1, example is described, preferably, the embodiment of the present invention can also be configured to example by the second, and principle is similar, repeats no more here.

When trunking receives R-ULgrant at subframe n, it sends R-PUSCH on subframe n+K.Here R-ULgrant can carry backhaul configuration numbering or descending uplink relay subframe ratio, or donor base station sends backhaul configuration numbering or descending uplink relay subframe ratio by other signalings; Afterwards, can find out according to table 11, if the backhaul configuration that trunking receives is numbered 0, namely corresponding descending uplink relay subframe is than 1:1, owing to only having subframe 8 when configuring 0 in backhaul for downlink relay sub-frame, that is, trunking can only receive R-ULgrant in subframe 8, now, K value can be joined and is shown in Table 12, and K value now should be able to ensure the uplink relay subframe of trunking finally when backhaul configures 0 sends R-PUSCH.Certainly, if backhaul configuration is numbered other values, such as 1,2 or 3, principle when analysis principle and above-mentioned backhaul configure 0 is similar, repeats no more here.As an embodiment of the present invention, here, for each different descending uplink relay subframe ratio, the sequential relationship between R-ULgrant and R-PUSCH shown in table 12 is embodiments provided.
