Via node (RN, Relay Node) three wireless links have appearred in the feasible mobile communication system based on Relay of introducing, that is: eNB-macro UE direct projection link (direct link), eNB-RN back haul link (backhaul link) and RN-relay UE access link (access link) below abbreviate direct link, backhaul link and access link respectively as.The transceiver of RN adopts the mode of operation of time division duplex (TDD, Time Division Dual), promptly receives and sends and can not carry out simultaneously.
The backhaul link can adopt identical frequency spectrum with the access link, but because the transmitter of RN has interference (unless can provide enough isolation to the signal that passes in and out) to own receiver, therefore descending backhaul link and descending access link are unsuitable for existing simultaneously on same frequency resource usually, and be up as the same.For avoiding above-mentioned interference, usually adopt following processing mode in the prior art: (eNB) receives data if RN is from the base station, then do not send data to UE, promptly utilize multicast single frequency network (MBSFN, Multicast/Broadcast over a SingleFrequency Network) subframe to create " gap " in the transmission time at descending access.Fig. 1 utilizes the MBFSN subframe to carry out the schematic diagram of repeated link downlink transfer for existing.As shown in Figure 1, in " gap ", RN only can receive the data from eNB, and can not send data to UE; " Ctrl " is used for RN and sends control signaling to UE, promptly UE dispatched.
Though mode shown in Figure 1 has solved interference problem, this mode has also been brought new problem, such as:
Fig. 2 is existing a kind of scheduling of resource mode schematic diagram.As shown in Figure 2, at subframe #n, UE receives the Physical Downlink Control Channel (PDCCH from RN, Physical Downlink ControlChannel), wherein carry RN to the uplink scheduling information of UE in subframe #n+k, correspondingly, UE will send Physical Uplink Control Channel (PUCCH to RN in subframe #n+k, Physical UplinkControl Channel) and Physical Uplink Shared Channel (PUSCH, Physical UplinkSharedChannel); RN receives R-PDSCH and R-PDCCH that eNB sends to RN after UE sends PUCCH, wherein carry eNB to the uplink scheduling information of RN in subframe #n+k, and correspondingly, RN will send R-PUCCH and R-PUSCH in subframe #n+k; Will cause in same subframe RN should carry out transmit operation like this, carry out reception operation again, thereby cause resource contention at UE at eNB.

Embodiment
At problems of the prior art, a kind of brand-new resource scheduling scheme is proposed: at the RN initial access network among the present invention, also do not begin before the actual communication, the sub-frame of uplink that is used to carry out the uplink of backhaul link that will be disposed to RN by eNB is notified to RN, like this, in the subsequent process, RN can not carry out uplink scheduling to UE in institute's collocating uplink subframe, thereby avoids causing resource contention.
In addition, though adopt mode shown in Figure 1 can solve interference problem, which subframe how not clear and definite RN to be known as the MBSFN subframe in the prior art.In the scheme of the present invention, can stipulate by eNB to be that the RN configuration is used to carry out the descending sub frame of backhaul link downlink transfer, and be notified to RN that RN is configured to the MBSFN subframe by existing mode with described descending sub frame then.
In actual applications, eNB can utilize different message, the descending sub frame that will be used to carry out the sub-frame of uplink of backhaul link uplink and be used to carry out backhaul link downlink transfer is notified to RN respectively, perhaps, also can utilize same message, the descending sub frame that will be used to carry out the sub-frame of uplink of backhaul link uplink and be used to carry out backhaul link downlink transfer is notified to RN simultaneously, and specific implementation is not limit.
For making purpose of the present invention, technical scheme and advantage clearer, below with reference to the accompanying drawing embodiment that develops simultaneously, the present invention is described in further detail.
Fig. 3 is the flow chart of the inventive method embodiment.Suppose in the present embodiment, adopt different message to be notified to RN respectively for the ascending-descending subframes of RN configuration.As shown in Figure 3, may further comprise the steps:
Step 301:eNB is that the RN configuration is used to carry out the sub-frame of uplink of backhaul link uplink and the descending sub frame that is used to carry out backhaul link downlink transfer, and is notified to RN.
In this step, the descending sub frame how eNB is used to carry out the sub-frame of uplink of backhaul link uplink for the RN configuration and is used to carry out backhaul link downlink transfer is a prior art, repeats no more, and introduces advice method below:
The MBSFN subframe advice method that a kind of maturation has been arranged in the prior art just is not applied between eNB and the RN, and this advice method is bitmap (bitmap) mode, comprises two kinds specifically:
A, single radio frames bitmap oneFrame BIT STRING (SIZE (6))
B, continuous four radio frames bitmap fourFrames BIT STRING (SIZE (24))
For adopting Frequency Division Duplexing (FDD) (FDD, Frequency Division Dual) system of pattern, each radio frames can be used as the MBSFN subframe in (comprising 10 subframes) subframe comprises: subframe 1, subframe 2, subframe 3, subframe 6, subframe 7 and subframe 8, respectively it is expressed as #1, #2, #3, #6, #7 and #8 in the present embodiment, corresponds respectively to 6 bits of bitmap.
For the system that adopts tdd mode, the subframe that can be used as the MBSFN subframe in each radio frames comprises: #3, #4, #7, #8 and #9, correspond respectively to preceding 5 bits of bitmap, and last 1 bit does not use; It should be noted that for tdd mode sub-frame of uplink can not be configured to the MBSFN subframe.
In the present embodiment,, realize being used to carry out the sub-frame of uplink of backhaul link uplink and the descending sub frame that is used to carry out backhaul link downlink transfer to RN notice for its configuration by eNB promptly by means of this existing advice method.
Wherein, for fdd mode, the sub-frame of uplink that is used to carry out the uplink of backhaul link both can be different subframes with the descending sub frame that is used to carry out backhaul link downlink transfer, also can be identical subframe, but tdd mode next can only be different subframes.For instance, #2 has been configured to be used to carry out the sub-frame of uplink of backhaul link uplink, so under fdd mode, #2 also can be further configured to being used to carry out the descending sub frame of backhaul link downlink transfer, but under tdd mode, #2 then can not be configured to be used to carry out the descending sub frame of backhaul link downlink transfer again.
In the present embodiment, preferably, can according to prior art in identical mode, under fdd mode, only permission is configured to #1, #2, #3, #6, #7 and #8 to be used to carry out the descending sub frame of backhaul link downlink transfer, promptly be configured to the MBSFN subframe, under tdd mode, only allow #3, #4, #7, #8 and #9 are configured to the MBSFN subframe.In addition, for the sub-frame of uplink that is used to carry out the uplink of backhaul link, do not have usually only to allow to use the restriction of which subframe, but preferably, can use #2, #3, #4, #7 and #8.
Need to prove, in the scheme of the present invention, for the upstream or downstream subframe that is disposed, can be same position with its position configuration in the different radio frame, such as fixing the #3 in each radio frames as the sub-frame of uplink that is used to carry out the uplink of backhaul link; Perhaps, can be the cycle such as M radio frames also with a certain number of, be configured to different positions.
Be example below with the tdd mode, above-mentioned two kinds of situations be elaborated respectively:
1) first kind of situation:
ENB will dispose the mode that the sub-frame of uplink that is used to carry out the uplink of backhaul link to RN is notified to RN: eNB sends a notification message that comprises the N bit to RN, N is a positive integer, the number of sub frames of sub-frame of uplink that can be used as the uplink of backhaul link in its value and each radio frames is identical, and with predefined 1 or 0 sub-frame of uplink of representing to dispose to RN that is used to carry out the uplink of backhaul link.ENB will dispose the mode that the descending sub frame that is used to carry out backhaul link downlink transfer to RN is notified to RN: eNB sends a notification message that comprises the N bit to RN, N is a positive integer, the number of sub frames of descending sub frame that can be used as backhaul link downlink transfer in its value and predetermined each radio frames is identical, and with predefined 1 or 0 descending sub frame of representing to dispose to RN that is used to carry out backhaul link downlink transfer.
Known in this field, according to the difference of uplink-downlink configuration, tdd mode can specifically be distinguished 7 spermotypes again, i.e. TDD configuration 0～TDD configuration 6.
Fig. 4 is based on the frame structure schematic diagram of the RN of TDD configuration 2 among this forwarding method embodiment.As shown in Figure 4, " D " expression descending sub frame wherein, " U " represents sub-frame of uplink, " S " represents special subframe; " M " represents MBSFN subframe (promptly being used to carry out the descending sub frame of backhaul link downlink transfer), the sub-frame of uplink that " T " expression is used to carry out the uplink of backhaul link.As can be seen, the #3 in each radio frames is configured in order to be used to carry out the descending sub frame of backhaul link downlink transfer, and #7 is configured in order to be used to carry out the sub-frame of uplink of backhaul link uplink.
The subframe of supposing to can be used as the sub-frame of uplink of backhaul link uplink is #2, #3, #4, #7 and #8, the value of so above-mentioned N will be 5, and suppose with 1 sub-frame of uplink of representing to dispose to RN that is used to carry out the uplink of backhaul link, so in conjunction with Fig. 4, the notification message that eNB sends to RN can be expressed as (owing to adopt the bitmap advice method, and be used for the collocating uplink subframe, so this notification message can be abbreviated as up bitmap):
Up bitmap:{#2, #3, #4, #7, #8}
{0，?0，?0，?1，?0}。
Equally, if it is #3, #4, #7, #8 and #9 that hypothesis can be used as the subframe of the descending sub frame of backhaul link downlink transfer, and suppose with 1 descending sub frame of representing to dispose to RN that is used to carry out backhaul link downlink transfer, in conjunction with Fig. 4, the notification message (abbreviating descending bitmap as) that eMB sends to RN can be expressed as so:
Descending bitmap:{#3, #4, #7, #8, #9}
{1，?0，?0，?0，?0}。
2) second kind of situation:
For the descending sub frame that is used to carry out backhaul link downlink transfer that is disposed, its advice method and 1) similar in, just need to adopt bitmap indicate M radio frames continuously.
Fig. 5 is based on the frame structure schematic diagram of the RN of TDD configuration 6 among this forwarding method embodiment.As shown in Figure 5, if #9 is configured to be used for the descending sub frame of backhaul link downlink transfer, so descending bitmap can be expressed as:
{#3，#4，#7，#8，#9，#3，#4，#7，#8，#9，#3，#4，#7，#8，#9#3，#4，#7，#8，#9，#3，#4，#7，#8，#9，#3，#4，#7，#8，#9}
{0，?0，?0，?0，?1，?0，?0，?0，?0，?1，?0，?0，?0，?0，?1，0，?0，?0，?0，?1，?0，?0，?0，?0，?1，?0，?0，?0，?0，?1，}。
But for the sub-frame of uplink that is used to carry out the uplink of backhaul link that is disposed, then need eNB to generate an allocation list in advance, comprise M option in this allocation list, be numbered option one respectively to option M, the configuration information of each option correspondence oneself, comprising: the sub-frame of uplink that is used to carry out the uplink of backhaul link of RN is given in configuration in each radio frames.
ENB sends an above notification message to RN, the corresponding option of each notification message, comprise N * M bit in each notification message, N is a positive integer, the number of sub frames of sub-frame of uplink that can be used as the uplink of backhaul link in its value and each radio frames is identical, and represents that with predefined 1 or 0 configuration in each radio frames gives the sub-frame of uplink that is used to carry out the uplink of backhaul link of RN.
Suppose that above-mentioned allocation list is (the M value is 6):
| ??10ms | ??10ms | ??10ms | ??10ms | ??10ms | ??10ms | |
| Option one | ??#2 | ??#3 | ??#4 | ??#7 | ??#8 | ?? |
| Option | ||||||
| 2 | ??#3 | ??#4 | ??#7 | ??#8 | ??N | ??#2 |
| Option 3 | ??#4 | ??#7 | ??#8 | ??N | ??#2 | ??#3 |
| |
??#7 | ??#8 | ??N | ??#2 | ??#3 | ??#4 |
| |
??#8 | ??N | ??#2 | ??#3 | ??#4 | ??#7 |
| |
??N | ??#2 | ??#3 | ??#4 | ??#7 | ??#8 |
The allocation list of table one when the M value is 6
Wherein, radio frames of each " 10ms " expression; N is illustrated in and does not dispose the sub-frame of uplink that is used to carry out the uplink of backhaul link in this 10ms.
As can be seen, 6 kinds of configuration modes are provided in the table one altogether, first kind of configuration mode is that option one is represented sub-frame of uplink that #2, #3, #4, #7 and #8 in first to the 5th radio frames are configured to be used to carry out the uplink of backhaul link respectively, the sub-frame of uplink that option 2 expressions are configured to be used to carry out the uplink of backhaul link respectively with #3, #4, #7, #8 and #2 in first, second, third, fourth and the 6th radio frames; Other is given unnecessary details no longer one by one.
Suppose eNB according to first kind of configuration mode, promptly be illustrated in figure 5 as the sub-frame of uplink that RN configuration is used to carry out the uplink of backhaul link, the eNB notification message that sends to RN can be expressed as so:
Up bitmap:
{#2，#3，#4，#7，#8，#2，#3，#4，#7，#8，#2，#3，#4，#7，#8#2，#3，#4，#7，#8，#2，#3，#4，#7，#8，#2，#3，#4，#7，#8}
{1，?0，?0，?0，?0，?0，?1，?0，?0，?0，?0，?0，?1，?0，?0，0，?0，?1，?0，?0，?0，?0，?0，?1，?0，?0，?0，?0，?0，?0}。
In actual applications, eNB can only select a kind of configuration mode, also can select the various configurations mode simultaneously.
In addition, in order to save signaling consumption, can also adopt other advice method.Such as: suppose that eNB only selects a kind of configuration mode, i.e. option one so then has:
Table one is kept among the RN, and eNB only need utilize 5bits to notify the bitmap{1 of first radio frames correspondence in the RN option one, and 0,0,0,0}; RN is known each sub-frame of uplink that is used to carry out the uplink of backhaul link that is disposed in other radio frames in the option one by question blank one.
Perhaps, eNB only is notified to RN with the numbering of option one, and RN is known each sub-frame of uplink that is used to carry out the uplink of backhaul link that is disposed by question blank one.
Perhaps, adopt other advice method, such as: be kept at the HARQ timing relationship among the RN in advance; ENB sends an above notification message to RN, and the notification message number is less than the ascending HARQ course number, carries an ascending HARQ course number in each notification message respectively; RN inquires about the pairing HARQ timing relationship of the HARQ process number that carries in each notification message, knows the sub-frame of uplink that is used to carry out the uplink of backhaul link that is disposed according to the HARQ timing relationship.
Step 302:RN receives the notification message from eNB, in being used to carry out the sub-frame of uplink of backhaul link uplink, UE is not carried out uplink scheduling, and the descending sub frame that will be used to carry out backhaul link downlink transfer is configured to the MBSFN subframe, in the MBSFN subframe, receive only data, do not send data to UE from eNB.
In this step, after RN receives bitmap from eNB, the descending sub frame of correspondence is configured to the MBSFN subframe, leaves the sub-frame of uplink of correspondence for up backhaul link.In the sub-frame of uplink of reserving, RN will can not carry out any uplink scheduling to UE, to avoid resource contention.
In the subsequent process, eNB also can be according to the data volume on the link between self and the RN, adjusts for the descending sub frame number that is used to carry out the sub-frame of uplink number of backhaul link uplink and be used to carry out backhaul link downlink transfer of RN to configuration.This adjustment can be triggered by eNB, also can be triggered by RN:
A, trigger by eNB:
ENB buffer status reporting (the BSR that RN reports in the statistics scheduled time, Buffer States Report), adjust the sub-frame of uplink number that is used to carry out the uplink of backhaul link that RN is given in configuration according to this BSR, if promptly the buffer state shows that the data volume of the RN eNB of giving to be sent is bigger, then increase the sub-frame of uplink number that RN is given in configuration, otherwise reduce; Simultaneously, eNB statistics self disposes the descending sub frame number that is used to carry out backhaul link downlink transfer to RN to buffering (buffer) state of RN transmission according to this buffer state adjustment in the scheduled time;
B, trigger by RN:
RN is according to the BSR situation that self reports to eNB in the scheduled time, send one to eNB and adjust request, request increases or reduces required number of sub frames, and eNB adjusts request according to this, adjusts the sub-frame of uplink number that is used to carry out the uplink of backhaul link that RN is given in configuration; Simultaneously, eNB statistics self disposes the descending sub frame number that is used to carry out backhaul link downlink transfer to RN to the buffer state of RN transmission according to this buffer state adjustment in the scheduled time.
