Technical field
The present invention relates to a kind of method of data that the transmission used by electronic device is encoded with polarization code and a kind of use The electronic device of the method.
Background technique
Currently, in the communications field 5G, it has been suggested that various technologies improve the reliability of control channel.It is logical in conventional LTE In letter system, physical downlink control channel (physical downlink control channel has been used；PDCCH) To carry down link control information (downlink control information；DCI), the down link control information Commonly used to indicate the downlink (downlink for every user apparatus；) or uplink (uplink DL；UL resource) It is specified.DCI has the different-format that may depend on specific deployment situation and change.Fig. 1, which is shown, distributes resource by DCI 101 Routine techniques.It can be the first user (user equipment according to DCI 101；UE) the first downlink of distribution license 102, And the second downlink license 103 can be distributed for second user.Permit in the first user according to the first downlink of DCI 102 when being decoded, and the first user will be from such as by physical down link sharing channel (physical downlink shared channel；PDSCH the physical resource of 102 instruction of the first downlink license in) obtains the payload of first user, and When second user according to the second downlink of DCI license 103 to being decoded, second will be from such as by second in PDSCH Another physical resource of 103 instruction of downlink license obtains described second payload.
Polarization code is the error correcting code being currently known.In the communications field 5G, it has therefore proved that polarization code can be used reliably The channel coding of control channel during testing at the scene.Therefore, it is used in the following 5G communication system as seen in Figure 2 Polarization code, it will be the channel coding schemes for being ready to use in transmission DCI 201 that described Fig. 2, which is painted polarization code,.Use the communication of polarization code Channel-polarization at two types channel because each channel will be almost muting channel or very noisy channel. Almost muting channel will be used for transmission, and very noisy channel does not use frozen and independent leave.Therefore, by The bit stream (namely polarization sequence) of polarization code coding will usually have by the almost information bit of muting transmission and Freeze position by very noisy transmission.
Fig. 3 shows the block diagram of the normal channel encoding scheme using polarization code.The polarization dependability sequence of size N kernel It is characterized by with position index U={ U0, U1..., UN-1, reliability is characterized as being W (U0)<W(U1)<…<W(UN-1), this meaning Taste higher position of indexing (higher indexed bits) be more reliable.Freeze index of set and is substantially characterized as being UF= {U0, U1..., U|UF|-1}.Including cyclic redundancy check (cycle redundancy check；CRC) the information of position or PC code bit Position is characterized as being UI={ U|UF|, U|UF-1|..., UN-1, UF, UF+1..., UN-1}.For example, feed-in sequencing is { B0, B1..., B910 positions and according to U depicted in Fig. 4iIndex is in U0、U1、…、UN-110 positions, the U are selected in the middleiIndex to It is used for transmission by the 64 bit polarization codes coding indexed from 0~63.It 10 positions will be by 64 most end 10 indexed index (indexes 401) it places, and therefore will be put by as plotted as shown in Figure 4 57 58 60 31 47 55 59 61 62 63 position of indexing It sets.
In general, it is assumed that there are it stays in the A position transmitted in the N number of bit stream encoded with normal polarization code, So A position will in the middle carrying of A most reliable positions (that is, most end A of reliability sequence U index), before being transmitted by Polarization Coding device coding.
Fig. 4 A shows typical Polarization Coding and decoding program.| A | the set A of position is placed in securing position in feed-in Into Polarization Coding device before formed size | B | > | A | bigger set B.After Polarization Coding, with size | B | collection Closing C can be by be received as size by receiver | B | the channel of the set Y of position transmits.Size | A | initial sets A' can be with Possibly through to carrying out self poling decoder | B | position, which is decoded from Y, restores.
Since A is expressed as A={ A0, A1 ..., A9 }, it is assumed that the size that the size of A is 10, B and C is 64, then C It will be the A for being encoded into 64 positions.Therefore, for the situation of Fig. 3, input bit on left side by be include A 10 positions 64 A position and 54 freeze position and are set as binary values 0, and the output bit on right side will be 64 positions.Fig. 4 B is shown as example The 64 Polarization Coding device of size that 10 positions are encoded.U index is from least reliably indexing most reliable index order.Therefore, It will be singled out to be placed to the most reliable U index bit in coding A.For the situation of Fig. 4,10 of U index bit are most reliable Position 401 is i=57,58,60,31,47 ..., 62,63).Remaining of U index bit is used as and is set as freezing for binary values 0 Position.Therefore, U is placed on reference to Fig. 4 B, A031In, A1 is placed on U47In, A2 is placed on U55In ... A9 is placed on U63In, etc..U Remaining position of index bit is set as binary values 0.By using the channel coding schemes of Fig. 3, the set of C can be calculated.
In order to further increase DCI reliability, it has been suggested that several technologies.One technology is the position by reducing routine DCI Number come using compact DCI.Due to usually being incited somebody to action with less position so that reliability improves, so this technology will improve The reliability of DCI.However there are disadvantage, the disadvantage includes system or dispatch reliability reduces and the number of blind Detecting increases Greatly.Another technology is to repeat transmission PDCCH.Although will inevitably increase however, repeating that transmission reliability will be improved Transmission delay.Therefore, during this time, it can be achieved that control channel reliability improves and also minimizes disadvantage described above simultaneously Technology can be helpful.

Specific embodiment
Now with detailed reference to present example embodiment of the invention, shown in the drawings of the exemplary embodiment Example.As long as possible, identical drawing reference numeral is in the accompanying drawings and the description to represent same or similar component.
The present invention proposes a kind of to transmit the method for data encode with polarization code and a kind of number that transmission is encoded with polarization code According to electronic device.The method is applicable to the control channel information of transmission such as DCI.Although rest part of the invention is retouched Transmission DCI (it is usually carried in PDCCH) is stated, but such as the expansible other types of control letter of technology described in the present invention Road information.In addition, the present invention proposes to transmit complete control channel information (for example, whole DCI) and is in compact form but has The duplicate control channel information (for example, compact DCI) of intelligence.
The control channel by polarization code coding that Fig. 5 shows one in an exemplary embodiment of the present invention is transmitted Scheme.The scheme of Fig. 5 is suitable for both complete DCI and compact DCI.Assuming that have determined that will be with the complete of bit sequence for base station DCI is transferred to user, and A represents complete DCI, then A can be split into two parts, i.e. A1 and A2 by the technology proposed, so that A =(A1U A2), wherein A1 is the first bit sequence and A2 is the second bit sequence.In other words, A1 be complete DCI a part and A2 is another part of complete DCI, but the present invention is not limited to DCI is only split into two parts.The technology of proposition extends to DCI is split into greater than two parts.The length of A1 can it is identical as the length of A2, be smaller than or the length greater than A2.
A1 will be placed into a part of the first transmission bit stream 501, and the first transmission bit stream is then by Polarization Coding device Coding, Cong Ke come to least reliable sequence, and stay at time T1 and transmit.First transmission bit stream 501 to be encoded will be into one Step includes being followed by the first of A1 to freeze position set F1.A2 will be equally placed into a part of the second transmission bit stream 502, and described Two transmission bit streams are then encoded by Polarization Coding device, and Cong Ke comes to least reliable sequence, and are stayed at time T2 and transmitted.This Outside, the second transmission bit stream 502 to be encoded is by same including being followed by the second A1 for freezing position set (F2).A1 is to be repeated once The first bit sequence.The coding of bit stream 501 is transmitted to first including A1 and to the second transmission bit stream 502 including A1 and A2 Coding can be based on any of polarization code technology.First transmission bit stream 501 will usually have identical with the second transmission bit stream 502 Length, and time T2 will occur in after time T1.
For the embodiment of Fig. 5, A1 is by more crucial information is contained than A2 and therefore transmits A1 first.In this example In property embodiment, the length ratio A2 long of A1 and therefore most of information are transmitted at time T1, and A1 will be then by such as user Receiver end decoding.The the second transmission bit stream 502 to be encoded transmitted at time T2 includes occupying the second transmission bit stream 502 The A2 of most securing position, and A1 will be repeated once in the more insecure position in position than A2.However, since A1 repeats one It is secondary, so A1 will equally be likely to reliably be decoded by user.After obtaining both A1 and A2, complete DCI will be except A2 it It is outer that there are also A1.
Fig. 5 A be painted one in an exemplary embodiment of the present invention by 64 Polarization Coding device of size coding The example of control channel transmission.With reference to the example of Fig. 5, it is assumed that A is 10 positions={ M0, M1, M2 ..., M9 }, A1 be 4 positions= { M0, M1, M2, M3 }, and A2 is 6 positions={ M4, M5 ..., M9 }.At time T1,4 A1 will freeze bit combination with 60 And it is loaded into the left side of 64 Polarization Coding device of size of Fig. 5 A.In particular, M0 is placed in U59, and M1 is placed in U61, M2 is placed in U62, and M3 is placed in U63.Therefore, the first transmission bit stream can be calculated by 64 Polarization Coding device of size 501 64 positions.At time T2, with A2 10 positions than freeze with 54 the position A1 of bit combination be placed on it is more reliable In position, then 64 total positions are loaded into the left side of 64 bit polarization encoders, wherein M4 is placed into U47, and M5 is placed into In U55, M6 is placed into U59, and M7 is placed into U61, and M8 is placed into U62, and M9 is placed into U64, and M0 is placed into U31, M1 is placed into U57, and M2 is placed into U58, and M3 is placed into U60.Therefore, it can polarize accordingly by the size 64 of Fig. 5 A Encoder calculates 64 positions of the second transmission bit stream 502.
In addition to the additional reliability using CRC bit to further increase A1 and A2, Fig. 6 shows the scheme similar with Fig. 5.This Outside, in the first transmission bit stream 601, A1 will be followed by CRC1, and A2 equally repeated in the second transmission bit stream 602 but A2 relative to The position of A1 is overturn.As depicted in Fig. 6, the first transmission bit stream 601 includes being encoded by polarization code and from can most come to least Sequence A1, sequence C RC1, sequence A2, sequence C RC12 and the sequence F1 reliably to sort.Exemplary embodiment compared to Fig. 5, First transmission bit stream 601 further comprises the first error correction position set CRC1, and first error correction position set can be based on Any of error correction scheme and the signal integrity for protecting A1.Second error correction position set (CRC12) will protect A1 With the combined signal integrity of subsequent A2.Similarly, the second transmission bit stream 602, which contains, is encoded by polarization code and from most reliably To sequence A2, sequence C RC2, sequence A1, sequence C RC21 and the sequence F2 least reliably to sort.It is exemplary compared to Fig. 5 Embodiment, the second transmission bit stream 602 further comprise third error correction position set CRC2, third error correction position set It can the signal integrity based on any of error correction scheme and protection A2.(CRC21) is gathered in 4th error correction position will Protect the combined signal integrity of A2 and subsequent A1.
For the first transmission bit stream 601, it is assumed that A1 in decoding without wrong, then can be examined by using CRC1 Survey and adjust the integrality of A1.Since A2 ratio A1 is transmitted in more insecure position, so A2 can have by using CRC12 It was found that uncorrectable error position.Even if A2 can not be decoded reliably, but at time T2, A2 transmits bit stream 602 second In repeat at highly reliable position.Since A1 is corrected and A2 is placed in securing position at time T2 at time T1, so A2 can be highly reliable at time T2.Once think that A2 is highly reliable after being verified by CRC2, it can be from A2+A1 Combination in choose A1 and A1 corrected by using CRC21.
It can be compared from the second transmission decoded A1 of bit stream 602 with the A1 from the first transmission bit stream 601, because false If the A1 from 602 the two of the first transmission bit stream 601 and the second transmission bit stream is identical.Similarly, may include repeat with And multiple modes of CRC check verify and correct the signal integrity of A2, the CRC check include CRC2, CRC21 and CRC12。
In general, after bit stream 601 is transmitted in reception first, user can transmit what bit stream 601 received to from first Data are buffered.Reception second transmit bit stream 602 after, user just will based on the A1 or A2 being placed in securing position and Most reliable bit stream is obtained from A1 or A2.After obtaining most reliable bit stream (it is one in A1 or A2), user will Another bit stream is obtained based on repetition and/or CRC check.
In order to be described in further detail as in Fig. 5 and Fig. 6 it is depicted using compact data, duplicate message and mistake more The concept of code, Fig. 7 show several variants of the control channel transmission by polarization code coding.It can be based on user relative to its clothes The deployed position of base station of being engaged in selects one in several variants.More specifically, Fig. 7 is painted including the first situation 701, second Four variants of situation 702, third situation 703 and the 4th situation 704.
For the first situation 701, the first transmission bit stream may include A1 and F1 and transmit at time T1, the second transmission position Stream may include the A2 for being followed by A1, and A1 is followed by F2.A1 in first situation 701 is repeated but for the second transmission bit stream more unreliable Position in.When operating under the first situation 701, all users can be decoded A1 at time T1.Alternatively, it uses Family can be divided into close to the base station edge customer (cell edge UE) of base station range edge and cover not close to base station The neighbor base station user of any edge of range.It is more unreliable since the signal of the edge of cell to be considered as, so must Both ask edge customer to obtain the first transmission bit stream at time T1 and obtain the second transmission bit stream at time T2, in order to lean on Ground obtains both A1 and A2.For the neighbor base station user that will obtain more reliable signal, neighbor base station user will only be needed The second transmission bit stream is decoded reliably to obtain both A1 and A2 at time T2.Therefore, in the first situation 701 Under, neighbor base station user can save power.
For the second situation 702, the first transmission bit stream may include A1, A2 and F1 and transmit at time T1, second Transmitting bit stream may include the A2 for being followed by F2.A2 in second situation 702 is repeated but for the first transmission bit stream more insecure In position.When operating under the second situation 702, neighbor base station user would only need to obtain the first transmission bit stream and pass to first Defeated bit stream is decoded to obtain both A1 and A2.Base station edge customer will transmit bit stream to from first transmitted at time T1 Decoded data are buffered.After receiving second transmitted at time T2 transmission bit stream, base station edge customer will Reliably the A2 from the second transmission bit stream is decoded.By the way that by A2, as effective priori information, base station edge customer will It can be reliably decoded to from the A1 through buffered data.
For third situation 703, the first transmission bit stream may include A2, A1 and F1 and transmit at time T1, second Transmitting bit stream may include the A1 for being followed by F2.A1 in third situation 703 is repeated but for the first transmission bit stream more insecure In position.When operating under third situation 703, neighbor base station user would only need to obtain the first transmission bit stream and pass to first Defeated bit stream is decoded to obtain both A1 and A2.Base station edge customer will transmit bit stream to from first transmitted at time T1 Decoded data are buffered.After receiving second transmitted at time T2 transmission bit stream, base station edge customer will Reliably the A1 from the second transmission bit stream is decoded.By the way that by A1, as effective priori information, base station edge customer will It can be reliably decoded to from the A2 through buffered data.
