Embodiment
For making the object, technical solutions and advantages of the present invention clearly, below in conjunction with accompanying drawing, embodiment of the present invention is described further in detail.
In the present invention, UE adopts uplink MEVlO transmissions mode to send data block to base station, UE adopts during uplink MEVlO transmissions mode can send multiple data block to base station in a TTI simultaneously, in a TTI, send 2 data blocks for UE to be below described simultaneously, the cardinal principle flow process of uplink MEVlO transmissions mode, is specially:
The first step, when base station starts to need UE transmission data block, the NDI generating also buffer memory two data blocks is respectively the ND2 of NDI and the TB2 data block of TB1 data block, transmission carries the upstream multi-antenna dispatch of the NDI of NDI and the TB2 data block of the TB1 data block of buffer memory to UE, and this upstream multi-antenna dispatch is used to indicate UE and adopts uplink MEVlO transmissions mode in same TTI, to transmit two data blocks to base station;
Second step, UE receives the upstream multi-antenna dispatch that base station sends first, according in advance and the base station rule of arranging from upstream multi-antenna dispatch, extract the NDI of NDI and the TB2 data block of TB1 data block, the NDI of NDI and the TB2 data block of the TB1 data block that buffer memory extracts, obtain TB1 data block and TB2 data block, and TB1 data block and TB2 data block are sent to base station;
Wherein, the rule that base station and UE arrange in advance is: the NDI of the NDI coming the data block of first in upstream multi-antenna dispatch to be the NDI of TB1 data block and the NDI of data block that comes second be TB2 data block, or the NDI of the NDI coming the data block of first in advance in agreement upstream multi-antenna dispatch to be the NDI of TB2 data block and the NDI of data block that comes second be TB1 data block; Buffer1 and Buffer2 is buffer.
3rd step, if base station successfully receives TB1 data block and TB2 data block, the NDI of NDI and the TB2 data block of the TB1 data block of upset buffer memory, the NDI of NDI and the TB2 data block of the TB1 data block of buffer memory is upgraded again according to the NDI of NDI and the TB2 data block of the TB1 data block after upset, transmission feeds back to UE and this feedback information carries two success flag, if base station also needs UE to continue the new data block of transmission, then base station sends upstream multi-antenna dispatch to UE and this upstream multi-antenna dispatch carries the NDI of NDI and the TB2 data block of the TB1 data block of buffer memory simultaneously,
Wherein, if base station receives TB1 data block and TB2 data block unsuccessfully, then base station directly sends and feeds back to UE and this feedback information carries two unsuccessfully identifies, and and then sends upstream multi-antenna dispatch and this upstream multi-antenna dispatch carries the NDI of NDI and the TB2 data block of the TB1 data block of buffer memory.
Wherein, the mode that base station adopts " 0/1 " to overturn overturns the NDI of NDI and the TB2 data block of TB1 data block, and such as, if the NDI value of the TB1 data block of buffer memory is " 0 " in base station, then the NDI value of the TB1 data block after upset is " 1 ".
4th step, UE receiving feedback information and upstream multi-antenna dispatch, according in advance and the base station rule of arranging from this upstream multi-antenna dispatch, extract the NDI of NDI and the TB2 data block of TB1 data block, the relatively NDI of TB1 data block of buffer memory and the NDI of the TB1 data block of extraction, if both are not identical, then obtain new TB1 data block; Relatively the NDI of TB2 data block of buffer memory and the NDI of the TB2 data block of extraction, if both are not identical, then obtains new TB2 data block, by two channels, new TB1 data block and new TB2 data block is sent to base station, then return execution the 3rd step.
Wherein, if UE compares, the NDI of the TB1 data block of buffer memory is identical with the NDI of the TB1 data block of extraction and to compare the NDI of the NDI of TB2 data block of buffer memory and the TB2 data block of extraction also identical, then show that base station receives TB1 data block and TB2 data block unsuccessfully, then UE sends TB1 data blocks and TB2 data block to base station by two channels again.
Wherein, base station and UE perform the 3rd step and the 4th step repeatedly, until when base station receives all upstream datas of UE transmission.
Wherein, in the third step, base station only may successfully receive one of them data block and another data block does not receive, or receive two data blocks and one of them data block makes a mistake, then now base station send feed back to UE and this feedback information carries a success flag and one unsuccessfully identify, immediately follows send up single antenna dispatch to UE and this up single antenna dispatch carries the NDI of a data block; Or base station find self and UE eat dishes without rice or wine second-rate time, send up single antenna dispatch to UE and this up single antenna dispatch carries the NDI of a data block; Up single antenna dispatch is used to indicate UE and adopts SISO transmission means to transmit a data block, and now UE needs to utilize method provided by the invention, determines to transmit which data block to base station.
Embodiment 1
As shown in Figure 1, embodiments provide a kind of method determining transmission data block, comprising:
Step 101: receive up single antenna dispatch, this up single antenna dispatch carries the NDI of the first data block;
Step 102: obtain indication information, this indication information is used to indicate described first data block;
Step 103: the NDI carried according to this up single antenna dispatch command, sends the first data block of this indication information instruction.
In embodiments of the present invention, receive base station and send the up single antenna dispatch carrying the NDI of the first data block, obtain the indication information being used to indicate the first data block, send the first data block of this indication information instruction to base station.So, UE is received after base station sends up single antenna dispatch, know which data block of transmission is to base station.
Embodiment 2
As shown in the figure, embodiments provide a kind of method determining transmission data block, comprising:
Step 201:UE receives the upstream multi-antenna dispatch that base station sends, and this upstream multi-antenna dispatch carries the NDI of NDI and the TB2 data block of TB1 data block, by two channels, TB1 data block and TB2 data block is sent to base station;
Wherein, when base station starts to need UE to send data block, first generate and the NDI of NDI and the TB2 data block of buffer memory TB1 data block, transmission carries the upstream multi-antenna dispatch of the NDI of NDI and the TB2 data block of the TB1 data block of buffer memory to UE again, and this upstream multi-antenna dispatch is used to indicate UE and transmits TB1 data block and TB2 data block by uplink MEVlO transmissions mode.Now, this step is specially:
UE receives the upstream multi-antenna dispatch that base station sends, according in advance and the base station rule of arranging from this upstream multi-antenna dispatch, extract the NDI of NDI and the TB2 data block of TB1 data block, the NDI of NDI and TB2 of the TB1 that buffer memory extracts, obtain two data blocks, using two data blocks of acquisition as TB1 data block and TB2 data block, respectively by TB1 data block and TB2 data-block cache in Buffer1 and Buffer2, then by two channels, the TB1 data block in Buffer1 and the TB2 data block in Buffer2 are sent to base station.
Wherein, after base station first time transmission upstream multi-antenna dispatch, UE can send TB1 data block and TB2 data block, if base station successfully receives TB1 data block and TB2 data block, the then NDI of NDI and the TB2 data block of the TB1 data block of base station upset buffer memory, the NDI of NDI and the TB2 data block of the TB1 data block of buffer memory is updated to the NDI of NDI and the TB2 data block of the TB1 data block after upset, then feedback information and this feedback information carries two success flag is sent, if base station also needs UE to transmit new data block, then send upstream multi-antenna dispatch to UE and this upstream multi-antenna dispatch carries the NDI of NDI and the TB2 data block of the TB1 data block of buffer memory simultaneously, if base station receives TB1 data block and TB2 data block unsuccessfully, then base station directly sends and feeds back to UE and this feedback information comprises two unsuccessfully identifies, and and then sends upstream multi-antenna dispatch to UE and this upstream multi-antenna dispatch carries the NDI of NDI and the TB2 data block of the TB1 data block of buffer memory.Now, this step is specially:
UE receives upstream multi-antenna dispatch, according in advance and the base station rule of arranging from this upstream multi-antenna dispatch, extract the NDI of NDI and the TB2 data block of TB1 data block, the comparison NDI of TB1 data block of buffer memory is with the NDI of the TB1 data block of extraction and compare the NDI of TB2 data block of buffer memory and the NDI of the TB2 data block of extraction, if the result compared is not for identical, the data block that then acquisition two is new again, and respectively as TB1 data block and TB2 data block, empty Buffer1 and Buffer2 and TB1 data block and TB2 data block are buffered in Buffer1 and Buffer2 respectively, by two channels, the TB1 data block in Buffer1 and the TB2 data block in Buffer2 are sent to base station, then the NDI of NDI and the TB2 data block of the TB1 data block of buffer memory is updated to respectively the NDI of NDI and the TB2 data block of the TB1 data block of extraction, if the result compared is for both identical, then show that base station receives TB1 data block and TB2 data block unsuccessfully, then UE sends the TB1 data block be buffered in Buffer1 and the TB2 data block be buffered in Buffer2 to base station by two channels again.
Wherein, after UE sends TB1 data block and TB2 data block, in Buffer1 and Buffer2, still retain TB1 data block and TB2 data block.In addition, upstream multi-antenna dispatch also carries the MCS (Modulation Code Scheme, coded system) of TB1 data block and/or MCS and/or RV of RV (Redundancy Version, redundancy versions) and TB2 data block; Upstream multi-antenna dispatch can be PDCCH (Physical Downlink Control Channel, Physical Downlink Control Channel) the DCI Format4 (Downlink Control Information Format4, descending control information format 4) of signaling format.
Wherein, the TB1 data block that UE sends and TB2 data block all take identical running time-frequency resource, but the channel sending each data block is all spatially mutually orthogonal, and thus TB1 data block and TB2 data block can be distinguished from each channel in base station.
Wherein, after UE sends TB1 data block and TB2 data block to base station at every turn, base station successfully may receive TB1 data block and TB2 data block, or receive TB1 data block and TB2 data block unsuccessfully, or only successfully receive one of them data block and another data block does not receive, or receive two data blocks and one of them data block makes a mistake.In addition, base station also likely find between self and UE eat dishes without rice or wine second-rate.
Wherein, if base station receives only one of them data block and another data block does not receive, or receive two data blocks and one of them data block makes a mistake time, then base station send feed back to UE and this feedback information carries a success flag and one unsuccessfully identify, and then send up single antenna dispatch to UE, and this up single antenna dispatch carries the NDI of a data block; Or if eating dishes without rice or wine between base station discovery self and UE is second-rate, then base station also can send up single antenna dispatch to UE, and this up single antenna dispatch carries the NDI of a data block.
Wherein, base station and UE arrange the NDI that up single antenna dispatch carries default data block in advance, and UE is used to indicate the indication information of default data block or arranges by RRC (Radio Resource Control, radio resource control) signaling the indication information that is used to indicate default data block by base station in UE self arranging one in advance.Such as, in the present embodiment, base station and UE arrange up single antenna dispatch in advance to carry default data block are TB1 data block, then this up single antenna dispatch carries the NDI of TB1 data block, then performs step 202.
Wherein, if base station successfully receives TB1 data block, the NDI of TB1 data block that then up single antenna dispatch carries is the NDI after upset, if base station receives TB1 data block unsuccessfully, then the NDI of TB1 data block that up single antenna dispatch carries is the NDI not occurring to overturn.In addition, up single antenna dispatch can be the DCI format0 of PDCCH signaling format.
Step 202:UE receives the up single antenna dispatch that base station sends, and this up single antenna dispatch carries the NDI of a data block;
Wherein, it should be noted that: up single antenna dispatch carries the NDI of TB1 data block, but UE do not know that NDI that up single antenna dispatch carries is the NDI of TB1 data block.
Step 203:UE obtains the indication information arranged in advance, and the TB1 data block of instruction is determined according to the indication information obtained, obtain the Buffer1 of buffer memory TB1 data block and the Buffer2 of another data block of buffer memory and TB2 data block, empty the TB2 data block of buffer memory in Buffer2;
The NDI of the TB1 data block that step 204:UE carries according to the NDI of the TB1 data block of buffer memory and up single antenna dispatch, sends TB1 data block to base station;
Particularly, UE compares the NDI carrying TB1 data block in the NDI of the TB1 data block of buffer memory and this up single antenna dispatch, if both are identical, then the TB1 data block in Buffer1 is sent to base station by a channel by UE, if both are not identical, then UE obtains new data block and it can be used as new TB1 data block, empty Buffer1 and by new TB1 data-block cache in Buffer1, by a channel, the TB1 data block in Buffer1 is sent to base station again, and the NDI of the TB1 data block of buffer memory is updated to the NDI that this up single antenna dispatch carries TB1 data block.
Wherein, UE also can not empty Buffer1, directly the data block in Buffer1 can be replaced with new TB1 data block.
Wherein, if it is identical that UE compares two NDI, then show that base station receives TB1 data block unsuccessfully, UE needs again transmission primaries TB1 data block to base station, if it is not identical that UE compares two NDI, then represent that base station successfully receives TB1 data block, the TB1 data block that UE needs transmission one new is to base station.
Wherein, if base station successfully receives the TB1 data block that UE sends, then the NDI of the TB1 data block of base station upset buffer memory, then the NDI of the TB1 data block of buffer memory is updated to the NDI of the data block of the TB1 after upset.Then base station can send and feed back to UE and this feedback information carries a success flag, if base station also needs UE to transmit new data block, then send upstream multi-antenna dispatch to UE simultaneously, and in this upstream multi-antenna dispatch, carry the NDI of NDI and the TB2 data block of the TB1 data block of buffer memory, then perform step 205.
If base station receives the TB1 data block that UE sends unsuccessfully, then base station directly sends and feeds back to UE and this feedback information carries one unsuccessfully identifies, and then send up single antenna dispatch to UE and this up single antenna dispatch carries the NDI of the TB1 data block of buffer memory, continue to perform step 202.
Step 205:UE receives the upstream multi-antenna dispatch that base station sends, according in advance and the base station rule of arranging from this upstream multi-antenna dispatch, extract the NDI of NDI and the TB2 data block of TB1 data block;
Step 206:UE, according to the NDI of the NDI of the TB1 data block of buffer memory and the TB1 data block of extraction, determines the data block of the TB1 in Buffer1;
Particularly, UE compares the NDI of the NDI of the TB1 data block of extraction and the TB1 data block of buffer memory, if both are not identical, then obtain new data block, using the data block of acquisition as new TB1 data block and the TB1 data block that empties in Buffer1, by the new TB1 data-block cache that obtains in Buffer1, and the NDI of the data block of the TB1 of buffer memory is updated to the NDI of TB1 data block of extraction, if both are identical, then retain the TB1 data block of buffer memory in Buffer1.
The NDI of the TB2 data block of buffer memory is updated to the NDI of the TB2 data block of extraction by step 207:UE, again obtains TB2 data block, and by the TB2 data-block cache that again obtains in Buffer2;
Wherein, because Buffer2 is cleared, the NDI value regardless of the TB2 data block in upstream multi-antenna dispatch is how many, all obtains new TB2 data block and is cached in buffer2.
TB2 data block in buffer memory TB1 data block in Buffer1 and Buffer2 is sent to base station by two channels by step 208:UE.
Wherein, if base station successfully receives TB1 data block and TB2 data block, the then NDI of NDI and the TB2 data block of the TB1 data block of base station upset buffer memory, the NDI of NDI and the TB2 data block of the TB1 data block of buffer memory is updated to the NDI of NDI and the IB2 data block of the TB1 data block after upset, then send and feed back to UE and this feedback information carries two success flag, if also need UE to transmit new data block, then send upstream multi-antenna dispatch to UE and this upstream multi-antenna dispatch carries the NDI of NDI and the TB2 data block of the TB1 data block of buffer memory simultaneously, if base station receives TB1 data block and TB2 data block unsuccessfully, then base station directly sends and feeds back to UE and this feedback information comprises the mark of two failures, and then send upstream multi-antenna dispatch to UE and this upstream multi-antenna dispatch carries the NDI of NDI and the TB2 data block of the TB1 data block of buffer memory, then return and perform step 201.
Wherein, if base station receives only one of them data block and another data block does not receive, or receive two data blocks and one of them data block makes a mistake time, now base station send feed back to UE and this feedback information carries a success flag and one unsuccessfully identify, and then up single antenna dispatch is sent to UE, and this up single antenna dispatch comprises the NDI of TB1 data block, if or base station find between self and UE eat dishes without rice or wine second-rate, then base station also can send up single antenna dispatch to UE, then return and perform step 202.
Wherein, in the present embodiment, it is TB2 data block that base station and UE also can arrange default data block in advance, determines that the process of transmission data block is identical with foregoing, no longer describes in detail at this.
