Specific embodiment
In order to which the purpose, technological means and advantage of the application is more clearly understood, the application is done below in conjunction with attached drawing
It is further described.
Transmitting terminal is at most repeatable in one cycle to transmit n times, and the initial data that n times generate is incomplete in terms of content
Identical, different part is that continuity and periodicity is presented, and shares n kind and sends sequence, is denoted as 1~n of serial number.It is wanted in receiving end
Want to obtain and repeat transmission bring gain, then needs to carry out data merging.
Transmitting terminal encoded, is generated after rate-matched, intertexture and is sent sequence, is if desired retransmitted, for simplicity process with
And the diversity sequence number of reduction storage, then what the transmission sequence retransmitted several times after transmitting first time was transmitted with first time
It sends sequence to be compared, obtains multiple diversity sequences.I.e. when the sequence that originator is sent in succession is presented a kind of periodic,
Transmission sequence several times subsequent in a cycle is subjected to comparison in difference with the transmission sequence of the first time in the period, is obtained
To diversity sequence.
In receiving end, if mistake after the data decision received for the first time, just start to receive the 2nd data, when reception number
When being more than 1 according to number, then the merging for receiving data is carried out.
Illustrate by taking the Physical Broadcast Channel PBCH in current 5th third-generation mobile communication technology 5G-NR agreement as an example.According to
NR agreement defined at present, PBCH TTI are 80ms, and every 20ms sends data, and the sequence content of four transmissions is incomplete
Original data sequence create-rule that is identical, being specifically shown in agreement 38.212.Due to original series difference, made in 4 20ms
Scramble sequence is not also identical, and the frame that 4 bits are had in different scramble sequences and scramble sequence is generated according to frame number
Number information distinguishes 20ms time interval.Shown in Figure 1, Fig. 1 shows the structure of two kinds of frame signals, and one is in field
When maximum SSB number is 64, another kind is SSB number of maximum when not being 64.
It is shown in Figure 2, Fig. 2 be the application with TTI be 80ms, every 20ms sends the sequences of a data, four transmissions
A kind of not exactly the same flow diagram for embodiment of content.Wherein, Fig. 2A is two data merged blocks and three data
A kind of flow diagram of merged block, Fig. 2 B are a kind of flow diagram of four data merged blocks.
When the first SSB data block of receiving end reception, LLRs is saved, and carry out decoding verification, if verification passes through, carried out
Descrambling, obtains the relevant informations such as frame number.
If received first SSB Data block check does not pass through, after 20 ms, the 2nd SSB is received；In initial data
Although continuity is presented in different piece, the initial data different piece sent for the first time can not shift to an earlier date since which serial number
Know, thus receiving end need by assuming that, phase carried out to the partial data of data block according to the diversity sequence received
It after the reversion answered handles, merges the data after reversion, then is decoded, CRC check, in this way, with the side assumed, attempted
Formula is come so that data block correctly merges.
Assuming that the frame number of the first data block is 00, at this moment, the content deltas of the second data block of characterization and the first data block
Sequence is the first diversity sequence；According to the first diversity sequence received, the part of the second data block is inverted, will be inverted
The second data block afterwards is merged with the first data block, that is, assuming that the SSB frame number received for the first time is 00, it at this time will wherein
One LLRs assumes according to frame number and leaves that the diversity sequence come carries out partial inversion operation, LLRs after inverting with
The LLRs of another block directly aligns addition；Data block after merging is decoded, CRC check, if by verification, into
Row descrambling, obtains the relevant informations such as frame number；If unverified,
Assuming that the frame number of the first data block is 01, at this moment, the content deltas of characterization third data block and the first data block
Sequence is the second diversity sequence；According to the first diversity sequence received, the part of the first data block is inverted, according to
Two diversity sequences invert the part of the second data block, by after reversion the first data and reversion after the second data into
Row merges, that is, assuming that the SSB frame number received for the first time is 01, LLRs therein is assumed and started according to frame number at this time to deposit
The diversity sequence to get off carries out partial inversion operation, and the LLRs after inverting directly aligns addition；To the data block after merging into
Row decoding, CRC check, if being descrambled by verification, obtaining the relevant informations such as frame number；If unverified,
Assuming that the frame number of the first data block is 10, at this moment, the content deltas of the 4th data block of characterization and the first data block
Sequence is third diversity sequence；According to the second diversity sequence received, the part of the first data block is inverted, according to
Three diversity sequences invert the part of the second data block, by after reversion the first data and reversion after the second data into
Row merges, that is, assuming that the SSB frame number received for the first time is 10, assumes and leave to come according to frame number by LLRs therein at this time
Diversity sequence carry out partial inversion operation, the LLRs after inverting directly aligns addition；Data block after merging is translated
Code, CRC check, if being descrambled by verification, obtaining the relevant informations such as frame number；If unverified,
Assuming that the frame number of the first data block is 11, the sequence at this moment receiving data block (i.e. the second data block) next time enters
Next cycle, due to not within the same period, the difference of this original data content twice is unclear, so not
Consider merging in this case, decoding judgement directly is carried out to the second data block at this time；I.e., it is assumed that the SSB received for the first time
Frame number is 11, and frame number is respectively 11 and 00 twice in this case, wherein due to being in two TTI, twice in initial data
Appearance is not necessarily the only frame number difference, and does not know specific different content, cannot merge, at this time then directly with second
The LLRs received is decoded, and whether the data block for then going verification to receive for the second time is correct.
It successively decoded, verified in the case of these four when above-mentioned received data merged block twice, as long as wherein a certain
It is secondary to verify successfully, then descramble and takes out frame number information；If unverified, third data block is received, to carry out three numbers
According to the merging of block.
When receiving third data block:
Assuming that the 3 SSB frame numbers received are followed successively by 00-01-10, according to the first diversity sequence, by the portion of the second data block
Point inverted, according to the second diversity sequence, the part of third data block inverted, by after reversion the second data block,
Third data block is merged with the first data block；That is, at this time by the LLRs of two of them block according to frame number hypothesis and difference
Sequence carries out partial inversion operation, and the LLRs after inverting directly is aligned with the LLRs of another block to be added；To the number after merging
It is decoded according to block, CRC check, if being descrambled by verification, obtaining the relevant informations such as frame number；If not passing through school
It tests, then
Assuming that the 3 SSB frame numbers received are followed successively by 01-10-11, according to the first diversity sequence, by the portion of the first data block
It point is inverted, according to the second diversity sequence, the part of the second data block is inverted, according to third diversity sequence, by the
The part of three data blocks is inverted；By the first data block after reversion, the second data block after reversion, the third number after reversion
It is merged according to block；That is, LLRs therein is carried out partial inversion operation according to frame number hypothesis and diversity sequence at this time, instead
LLRs after turning directly aligns addition；Data block after merging is decoded, CRC check, if carried out by verification
Descrambling, obtains the relevant informations such as frame number；If unverified,
Assuming that the 3 SSB frame numbers received are followed successively by 10-11-00, at this time since three blocks are not located in the same TTI, no
Can directly it be merged three times, and due to merging twice before 10-11, so only needing directly to be received with third time in this case
LLRs decoded, whether correct then go verification third time to receive.
Assuming that the 3 SSB frame numbers received are followed successively by 11-00-01, in this case since those latter two blocks are in the same TTI
In, latter two can be merged, at this moment, go to merge according to the method merged twice, then successively verification sees whether pass through,
That is, the part of the second data block is inverted according to the first diversity sequence received, by after reversion the second data block with
First data block merges, and the data block after merging is carried out decoding verification.
If these four hypothesis when merging three times all not over verification, need to receive after 20ms the 4th SSB with
Carry out the merging of four data blocks.
When receiving four data blocks,
Assuming that received 4 data block frame numbers are followed successively by 00-01-10-11, it can merge just in this case and receive
The LLRs of wherein three blocks is carried out partial inversion operation according to frame number hypothesis and diversity sequence at this time by the LLRs of four blocks,
LLRs after reversion is directly aligned with the LLRs of another block to be added；That is, according to the first diversity sequence, by the second data block
Part is inverted, and according to the second diversity sequence, the part of third data block is inverted, will according to third diversity sequence
The part of 4th data block is inverted；By the second data block after the first data block, reversion, the third data block after reversion,
The 4th data block after reversion merges；Data block after merging is decoded, CRC check, if by verification, into
Row descrambling, obtains the relevant informations such as frame number；If unverified,
Assuming that received 4 data block frame numbers are followed successively by 01-10-11-00, due to the 4th data block and the first data block,
Second data block, third data block are not located in the same TTI, and this hypothesis lower need to directly decode, verify the 4th time and receive
LLRs；If being descrambled by verification, obtaining the relevant informations such as frame number；If unverified,
Assuming that received 4 data block frame numbers are followed successively by 10-11-00-01, at this point, since the first, second data block is preceding
It states unverified when being merged twice, therefore only merges the data block for being in different TTI, that is, received twice after merging
LLRs.The method that the method specifically merged merges according to two goes merging；If the data block after merging passes through verification,
Descrambled, obtains the relevant informations such as frame number；If unverified,
Assuming that received 4 data block frame numbers are followed successively by 11-00-01-10, according to the method merged three times under this hypothesis
The LLRs received three times after merging is removed, then successively does verification, that is, according to the first diversity sequence, by the portion of the second data block
Point inverted, according to the second diversity sequence, the part of third data block inverted, by after reversion the second data block,
Third data block after reversion is merged with the first data block, and the data block after merging is decoded and verified.If there is
Certain has passed through verification, then descrambles taking-up relevant information；If four kinds are assumed all not by verifying,
Lose the first SSB, then go after 20ms to receive the 5th SSB again, with receive second and third, four, five this 4 SSB go
Do the merging of four data blocks, at this moment, using second and third, four, five data blocks as in same period first, second and third,
Four data blocks return and assume the step of receiving 1 call number of sequence number when receiving four data blocks.
In terms of the above process, based on that will assume frame number after each reception data, four kinds of situations are needed to be traversed for, for this purpose, can
To characterize the reliability of certain hypothesis with an index, thus to reduce the number of traversal, reduce complexity.The application is to merge
The size of the absolute value of LLRs before decoding later, to characterize the reliability of the hypothesis, the absolute value of LLRs is bigger, then determines
The hypothesis is more reliable.It since frame number 11-00 has no idea to merge, can only directly go to receive subsequent data chunk, so setting is this
The weight of the absolute value of LLRs under assuming that is 1~2, and by emulation, general weight complexity when 1.3 can be dropped to
1.8。
Shown in Figure 3, Fig. 3 is a kind of sequence flow chart by taking two transmission blocks merge as an example.
Firstly, after calculating separately that each assumed condition is lower and merging the absolute value of each data block LLRs size, it may be assumed that
Under the first assumed condition, by the absolute value of the LLRs of the second data block after reversion, the LLRs of the first data block
Absolute value summation, obtain the first LLRs absolute value；
Under the second assumed condition, by the first data after the absolute value of the LLRs of the second data block after reversion, reversion
The absolute value of the LLRs of block is summed, and the 2nd LLRs absolute value is obtained；
Under third assumed condition, by the first data after the absolute value of the LLRs of the second data block after reversion, reversion
The absolute value of the LLRs of block is summed, and the 3rd LLRs absolute value is obtained；
Under the 4th assumed condition, the absolute value of the LLRs of the second data block is weighted according to weight, obtains the 4th
LLRs absolute value；
Then, the LLRs absolute value being calculated is ranked up, is determined according to the descending order of LLRs absolute value
Data block decoding sequencing.For example, if
First LLRs absolute value > the 2nd LLRs absolute value > the 3rd LLRs absolute value > the 4th LLRs absolute value, then decode
Precedence is according to prioritization are as follows:
The data block > third merged under the second assumed condition of data block > merged under first assumed condition assumes item
Data block under the 4th assumed condition of data block > merged under part
Shown in Figure 4, Fig. 4 is the application so that receiving end merging is multiple when I data block of transmission in a cycle of starting
A kind of flow diagram of data block.When the data block sent in a cycle is I, then need to assume I kind situation, and
The data block of every kind of hypothetical situation is attempted to merge.The specific method is as follows:
Step 401, when receiving data block i, data block i is decoded, is verified, if verification failure, receives
Subsequent data chunk；
Step 402, it is assumed that transmit Sequence Number n of the data block i in current period currently assumes sequence based on the i-th data block
Row number sets sequence number for successively received all data blocks, with formation sequence relationship；
Step 403, according to diversity sequence between the corresponding each data block of sequence relation, data block in current period is carried out
Partial inversion, and according to the sequence relation, the data block of each reversion and each data block not inverted are merged；It will close
And data block carry out decoding verification, if verified successfully, descramble, obtain frame number；Otherwise, step 404 is executed；
Step 404, according to sequence relation, data block and data block i are judged whether there is not in same period, that is, judgement is
It is no to have data block in second round, wherein second round is the next period adjacent with current period；If there is data block and number
According to block i not in same period, 405 are thened follow the steps；Otherwise, illustrate that received data block all in current period, thens follow the steps
406, at this moment, illustrate the data block merged under current hypothetical situation be it is incorrect, then carry out a kind of hypothesis of lower situation.
Step 405, judge whether the data block of second round is unique, if uniquely, which is carried out decoding school
It tests, if verification failure, thens follow the steps 406, if verified successfully, descramble, obtain frame number；When the data block of second round
When not unique, then using the data block of second round as the data block of current period, and go to step 403, with attempt merge, with
And the decoding verification of the data block after merging.
Step 406, it will be assumed that current sequence number n be incremented by, whether the sequence number after judgement is incremented by is greater than N, and wherein N is the
The maximum value that transmits Sequence Number of the i data block in current period illustrates that data i works as if the sequence number after being incremented by is greater than N
All hypothetical situations in preceding period are all traversed rear but still fail to need to receive next data by verification, therefore receive next
Data block, and sequence number is reset；If the sequence number after being incremented by is not more than N, current sequence number n is updated to after being incremented by
Value, returns to step 402.
Step 407, after having received next data, judge whether received data block total amount is equal to the number in a period
According to block sum I, if it is not, then returning to step 402；If it is, giving up data block i, since at this moment institute is received
Remaining given up except data i is then received data block as in current period all with data block i not in same period by data block
Data block, and using the first data block in the period as data block i, then return step 402, until attempting the number after merging
According to block check success, then descrambles, obtain frame number；Otherwise, then terminate.
Shown in Figure 5, Fig. 5 is the method test case simulation result using multiple and different transmission merged blocks of the application
Figure.In test case, four kinds of frame numbers assume the frame number for all assuming that first SSB block, the frame for the SSB block being then successfully received
It number successively increases；The method of LLRs reversion: it is starting, is setting 0 entirely other than frame number for original bit, then respectively by frame number
01,10,11 are set as, then these three original series are encoded respectively and rate-matched, three longer sequences are obtained
It arranges (sequence 1 and 2 and 3), and preserves；In receiving end, corresponding reversion is done to LLRs according to frame number hypothesis.That is:
When frame number is 01, then the sequence 1 preserved according to originator is only needed to invert, it is corresponding when the value of sequence 1 is 1
The LLR of position carries out polarity reversion, and when the value of sequence 1 is 0, the LLR of corresponding position is constant, then can be direct after LLRs transformation
Contraposition is carried out with the LLRs of another block to add；
When frame number is 10, then the sequence 2 preserved according to originator is only needed to invert, the rule of reversion is as above.
When frame number is 11, the sequence 3 preserved according to originator is needed to invert, the rule of reversion is as above.
