After obtaining modulation symbol using above-mentioned modulation system, when using the HARQ technical transmission modulation symbol, retransmits and divide The merging of group will be such that reliability difference between the bit position in mapping symbols increases, so as to cause bit error rate increase；Work as error code After rate increase, due to wireless communication system receiving end can not correct decoding, therefore, it is necessary to repeatedly retransmit, thus when increasing Prolong, affects the transmission performance of wireless communication system.
In consideration of it, the embodiment of the present invention provides a kind of data processing method, this method is applied in wireless communication system.? In this method, the transmitting terminal in wireless communication system determines information bit according to encoder matrix and data block to be sent first Field and the first check bit field or information bits field, the first check bit field and the second check bit field；So Afterwards, L bits to be sent are determined from multiple bit field, the L bits to be sent include at least one bit field, At least one bit field is at least one of information bits field and the first check bit field or at least one ratio Special field is at least one of information bits field, the first check bit field and second check bit field, and, this is extremely A few bit field has at least one priority division mode；Finally, transmitting terminal is according to the bit field that priority is high In bit priority be mapped in the high modulation symbol of reliability step bit position rule, by L bit maps to be sent On L bit position for including to modulation symbol, and export the modulation symbol, wherein the information bits field be with it is to be sent The identical bit sequence of data block or data block to be sent is weighted the bit sequence that conversion process obtains, this One check bit field is to carry out the ratio that coded treatment obtains to the data block to be sent using the first part of encoder matrix Special field, the second check bit field are to be compiled using the second part of the encoder matrix to the data block to be sent The bit field that code processing obtains.

The network equipment to data block to be transmitted carry out coded treatment when, can be directly used preset encoder matrix into Row coding；First preset encoder matrix can also be extended using the matrix of Z × Z, the encoder matrix after being expanded, Then coded treatment is carried out to the data block using the encoder matrix after extension.Wherein, the matrix of the Z × Z can be size and be One of matrix after the full null matrix or unit matrix of Z × Z or the column cyclic shift of unit matrix, Z be extension because Son, Z are more than or equal to 2 positive integer.
Since the structure of preset encoder matrix is different, the structure for the bits of original sequence that the network equipment obtains in encoded Also different.According to the two of preset encoder matrix kinds of structures, the structure of bits of original sequence is also classified into two kinds:
The first bit architecture:
When preset encoder matrix is the first matrix structure, the bits of original sequence that the network equipment obtains includes information Bit field S, the first check bit field P1 and the second check bit field P2.Information bits field S be with it is to be sent Data block to be sent is weighted the bit sequence that conversion process obtains by the identical bit sequence of data block, for example, to The data block of transmission is " 01101101 ", then information bits field S is also " 01101101 "；Or data block to be sent is Data block to be sent is multiplied by " 01101101 " with a weighting matrix, and obtained bit sequence is information bits field S, the weighting matrix can be invertible matrix etc., and this is not restricted.First check bit field P1 is using preset The bit field that the first part of encoder matrix is encoded to sent data block, can be using first part The bit field that is encoded to sent data block of whole elements, be also possible to the part member using first part The bit field that element is encoded to sent data block.Second check bit field P2 is to use preset coding square The bit field that the second part of battle array is encoded to sent data block can be all members using second part The bit field that element is encoded to sent data block is also possible to the Partial Elements using second part to pending The bit field that the data block sent is encoded.
Second of bit architecture:
When preset encoder matrix is second of matrix structure, the bits of original sequence that the network equipment obtains includes information Than field S and the first check bit field P1.The verification of information bits field S and first in second of bit architecture Bit field P1 is identical as the definition of information bits field S and the first check bit field P1 in the first bit architecture, Details are not described herein.
In one possible implementation, the information bits field in two kinds of bit architectures is further divided into the first information Bit field S1 and the second information bits field S2.First information bit field S1 be in the preceding N column element of first part The corresponding bit field of preceding K column element, for example, K be 2；Second information bits field S2 be with before the removing of the preceding N column element The corresponding bit field of element except K column.It in actual use, can be according to the channel capacity of wireless communication system Or configuration information etc. is one of above-mentioned bit architecture come the structure for determining bits of original sequence, this is not restricted.
It in embodiments of the present invention, is encoder matrix, i.e. LDPC code used in LDPC coding with preset encoder matrix, And the structure of the LDPC code be the first matrix structure for, the method in the embodiment of the present invention to be described in detail.
The size of LDPC code is mb × nb, in one possible implementation, mb=18, nb=34, such as Fig. 6.LDPC The first part of code includes the matrix element of the box on the left side Fig. 6, and second part includes the matrix element of the box on the right of Fig. 6. After being extended LDPC code using spreading factor Z, the LDPC code after reusing extension encodes data block to be transmitted Afterwards, bits of original sequence as shown in Figure 7 is obtained, the number of bits of the bits of original sequence is LA.Wherein, information bit word The number of bits that section S includes is LS, and identical as the bit sequence in data block to be transmitted, the first check bit field P1 is The obtained bit sequence of coded treatment is carried out to data block to be transmitted using the first part of LDPC code, it includes bit Number is LP1, and the second check bit field P2 is to be carried out at coding using the second part of LDPC code to data block to be transmitted Manage obtained bit sequence, it includes number of bits be LP2.
Step 502: the initial position of L bits to be sent is determined from bits of original sequence.
In one possible implementation, the network equipment can be true using the method for determining initial position in the prior art Determine the initial position of L bits to be sent, details are not described herein.
In one possible implementation, the network equipment can determine rising for L bits to be sent with the following method Beginning position:
+ 1 bit of V of bits of original sequence is determined as to the initial position of L bits to be sent, wherein 0≤V < LA.The determination method of numerical value V is as follows:
Method 1: according to the number of bits LA of bits of original sequence, spreading factor Z and RV, determining the value of numerical value V, meter Calculation method meets:
(1) V=RV1×Z+V0；
Wherein, V0 is integer, for example, V0 is the integral multiple of spreading factor Z；RV1To be less than or equal in all values of RV The integer of the columns n b of preset encoder matrix, and
Wherein, f (t)=t orOr
It should be noted that there are many values by nb, and it can be different according to different practical applications, it can be preset volume The maximum value of code matrix column number nb, such as 34, it is also possible to the minimum value of the columns n b of preset encoder matrix, such as 20.
The initial position of the L bits to be sent determined by the above method is the integral multiple of Z, to make wireless communication system System can support to take Z as the rate-matched and adaptive scheduling transmission for being grouped the packet level of unit.Simultaneously as RV1For RV All values in be less than or equal to preset encoder matrix columns n b integer, to make the expense of the control information of RV can To carry out dynamic adjustment according to the size of the encoder matrix of actual use, that is, be no more thanSuch as in nb=32 When, the information overhead of RV is no more than 5 bits, so as to reduce wireless communication system RV control information expense.

Or
Or
Wherein, V0 is integer, for example, V0 is the integral multiple of spreading factor Z；Ntx is positive integer, for example, Ntx is initial Bit sequence or a transmission block (Transport Block, TB) or the maximum of code block (Code Block, CB) pass Defeated number, alternatively, Ntx is the number of all values of RV.RV1For more than or equal to 0 and be less than Ntx integer, for example, RV1It can Be RV all values in one.Z1 is the positive integer times of spreading factor Z, and Z2 is the common multiple of Z1 and Ntx, Z3 Z1 With the common multiple of N1, Z4 is the common multiple of Z1 and (Ntx-N1).L1=LS+LP1.
Wherein, f (t)=t orOr
In one possible implementation, the applied field that the value of Ntx can also be different according to the wireless communication system Preset encoder matrix is arranged in scape or the network equipment.As shown in table 1- table 2, in table 1, when wireless communication system is answered For superelevation reliably with the communication of low latency (Ultra-Reliable and Low Latency Communications, URLLC) when scene, the value of Ntx is 1 and/or 2, i.e. Ntx can be a fixed value, two values can also be taken, in Ntx When taking two values, the specific value of Ntx can be determined using method as shown in Table 2.For example, the size of encoder matrix is 10 The value of × 20, Ntx are 1, and when the size of encoder matrix is 8 × 32, the value of Ntx is 2；When wireless communication system application in When enhanced mobile broadband (Enhanced Mobile Broadband, eMMB) scene, the value of Ntx is 4 and/or 6；Work as nothing Line communication system applications communicate the field (Massive Machine Type Communications, mMTC) in large-scale machines class The value of Jing Shi, Ntx are 6 and/or 8.In table 2, encoder matrix 1, encoder matrix 2 and encoder matrix 3 indicate three kinds it is different Encoder matrix is encoder matrix of different sizes respectively, for example, the size of encoder matrix 1, encoder matrix 2 and encoder matrix 3 It respectively can be 10 × 20,8 × 32 and 20 × 60, the value of Ntx is then related to the columns of encoder matrix, the column of encoder matrix Number is bigger, then the value of Ntx is bigger.With the size of encoder matrix 1, encoder matrix 2 and encoder matrix 3 respectively can for 10 × 20, for 8 × 32 and 20 × 60, the value that the columns of encoder matrix 1 is 20, Ntx is 2 and/or 4；The columns of encoder matrix 2 Value for 32, Ntx is 6；The value that the columns of encoder matrix 3 is 60, Ntx is 8.

When determining the initial position of L bits to be sent by the above method, since Ntx can be TB or CB Maximum transmission times, so that the expense of the control information of the RV of wireless communication system be allow to be carried out according to maximum transmission times Dynamic adjusts: the expense of the control information of RV isIt is passed for example, LTE system defines the maximum of a TB block Defeated times N tx is 4 times, so that the expense of the control information of RV is 2 bits, can reduce the control of the RV of wireless communication system The expense of information.
Method 2: according to the number of bits LA of bits of original sequence, number of bits L and RV to be sent, determine numerical value V's Value, calculation method meet:
V=(RV1×L+V0)mod LA；
Wherein, RV1For the integer more than or equal to 0 and less than Ntx, the definition of Ntx and value are identical as method 1, herein It repeats no more.The number of bits L of bits L to be sent, which can be, to be pre-set, for example, LTE system allows to pass every time Defeated number of bits is no more than 4536, then L takes the integer less than or equal to 4536.
When determining the initial position of L bits to be sent by the above method, since Ntx can pass for the maximum of CB Defeated number, and the value of L is determined according to the resource allocation size of default configuration, is a fixed value, to make wireless Corresponding initial position is identical in each code block of communication system, and so that wireless communication system is supported with CB is grouping unit The rate-matched and SPS scheduled transmission of code block grade.
Method 3: according to the number of bits LA and RV of bits of original sequence, determine that the value of numerical value V, calculation method meet:
V=RV1+V0；
Wherein, RV1For the positive integer less than (LA-V0).
When determining the initial position of L bits to be sent by the above method, due to RV1Value be according to number of bits LA's and V0 determines, so that so that wireless communication system is supported with bit is the rate for being grouped the bit-level of unit With being transmitted with adaptive scheduling.Correspondingly, the expense of the control information of RV isFor example, the wireless communication System is applied in the coded treatment scene that the number of bits of data block to be sent is 16 and encoder bit rate is 1/4, at this point, The number of bits LA of bits of original sequence is 64, then the expense of the control information of RV is no more than 6 bits, so as to reduce nothing The expense of the control information of the RV of line communication system.
After the value for determining numerical value V, the network equipment then determines several initial positions according to numerical value V, initial position Number is identical as the number of the value of RV, and by taking the value of RV is 0,1,2,3 as an example, then the network equipment is according to of the value of RV Number determines 4 V values, and then determines 4 initial positions as shown in Figure 8.
It should be noted that only selecting one and this from determining multiple initial positions when the network equipment transmits every time The corresponding initial position of secondary transmission, for example, can be selected from multiple initial positions any one initial position as with this It is secondary to transmit corresponding initial position；It can also be in advance the value of transmission one RV of fixed configurations every time, every time when transmission, then The value for transmitting corresponding RV with this is determined first, and the value pair with the RV determined is then selected from multiple initial positions The initial position that the initial position answered is transmitted as this.For example, the value of RV when presetting transmission for the first time is 0, for the first time The value of RV when re-transmission is 2, and the value of RV when retransmitting for the second time is 4, if being then this time transmitted as transmitting for the first time, selection and RV =0 corresponding initial position is the initial position transmitted for the first time.
Step 503: L bits to be sent are determined from bits of original sequence.
After the network equipment determines multiple initial positions, then according to the value of the corresponding RV when previous transmission, from initial ratio L bit, i.e. L bits to be sent are successively read in special sequence.In embodiments of the present invention, the value of L can be sets in advance It has been set that, for example, the network equipment can be to be sent to determine according to default configuration or the resource allocation size of dynamic configuration The number of bits L of bit.
Fig. 9 A is please referred to, if corresponding RV=0 when current transmission, the network equipment is from initial position corresponding with RV=0 L bit is successively obtained, L bits to be sent are obtained.
Fig. 9 B is please referred to, if corresponding RV=2 when current transmission, the network equipment is from initial position corresponding with RV=2 Circulation obtains L bit, obtains L bits to be sent.
Step 504: determining the preferential of each bit field at least one bit field that L bits to be sent include Grade.
In the network equipment after determining L bits to be sent in bits of original sequence, the network equipment determines that L is a pending first At least one bit field for sending bit to include, for example, L bits to be sent are L bit shown in Fig. 9 B, this L ratio The whole bits and the first check bit of whole bits, information bits field S in spy including the second check bit field P2 Partial bit in field P1, thus the L bits to be sent include information bits field S, the first check bit field P1 with And the second check bit field P2.Then, the priority of each bit field is determined according to a kind of priority division mode. Wherein, which can be one of a variety of preset priority division modes mode.In the present invention In embodiment, preset multiple priorities division mode includes following ten kinds:
The first priority division mode: the priority of information bits field S is the first priority and check bit word The priority of section P is the second priority, and the first priority is higher than the second priority, and check bit field includes the first verification ratio Special field P1 and/or the second check bit field P2.
It should be noted that when including information bits field S and the first check bit field in L bit fields to be sent When P1, it is determined that the priority of information bits field S is higher than the first check bit field P1；When in L bit fields to be sent When including information bits field S, the first check bit field P1 and the second check bit field P2, it is determined that information bit The priority of field S is higher than the first check bit field P1 and the second check bit field P2, and the first check bit field The priority of P1 is identical as the priority of the second check bit field P2.
Second of priority division mode: the priority of information bits field S is the first priority, the first check bit word The priority of section P1 is that the priority of the second priority and the second check bit field P2 are third priority, and first is preferential Grade is higher than the second priority, and the second priority is higher than the third priority.
The third priority division mode: the priority of information bits field S is the first priority, the second check bit word The priority of section P2 is that the priority of the second priority and the first check bit field P1 are third priority, and first is preferential Grade is higher than the second priority, and the second priority is higher than third priority.
4th kind of priority division mode: the priority of check bit field P is the first priority and information bit word The priority of section S is the second priority, and the first priority is higher than the second priority.
It should be noted that when including information bits field S and the first check bit field in L bit fields to be sent When P1, it is determined that the priority of the first check bit field P1 is higher than information bits field S；When in L bit fields to be sent When including information bits field S, the first check bit field P1 and the second check bit field P2, it is determined that the first verification The priority of bit field P1 and the priority of the second check bit field P2 are the first priority, and priority is higher than letter Cease the priority of bit field S.
5th kind of priority division mode: the priority of the first check bit field P1 is the first priority, the second inspection The priority of bit field P2 is that the priority of the second priority and information bits field S are third priority, and first is excellent First grade is higher than the second priority, and the second priority is higher than third priority.
6th kind of priority division mode: the priority of the second check bit field P2 is the first priority, information bit The priority of field S is that the priority of the second priority and the first check bit field P1 are third priority, and first is excellent First grade is higher than the second priority, and the second priority is higher than third priority.
7th kind of priority division mode: the priority of the first check bit field P1 is the first priority, information bit The priority of field S is that the priority of the second priority and the second check bit field P2 are third priority, and first is excellent First grade is higher than the second priority, and the second priority is higher than third priority.
8th kind of priority division mode: the priority of the first check bit field is the first priority and the second inspection The priority for testing bit field is the second priority, and the first priority is higher than the second priority.
9th kind of priority division mode: the priority of the second check bit field is the first priority and the first inspection The priority for testing bit field is the second priority, and the first priority is higher than the second priority.
Tenth kind of priority division mode: the priority of the second check bit field is the first priority, and first examines ratio The priority of special field is that the priority of the second priority and information bits field is third priority, and the first priority is high In the second priority, the second priority is higher than third priority.
It should be noted that can not include information bits field in L bits to be sent, for example, can be only when retransmitting Retransmit the first check bit field and the second check bit field.And L bits to be sent can only include a bit words Section, at this point, L bits to be sent have the same priority, for example, L bits to be sent are the first priority.
In embodiments of the present invention, constellation rearrangement skill can be passed through in whole or in part in above-mentioned priority division mode Art is realized.
When the network equipment transmits the data block to be sent for the first time, the network equipment can be divided from above-mentioned ten kinds of priority A kind of division mode is selected in mode, and the priority at least one bit field that L bits to be sent include is drawn Point.
In order to further decrease bit error rate when data are transmitted in wireless communication system, it is to be sent that this is retransmitted to the network equipment Data block when the priority division mode that uses proceed as follows:
The first: when the network equipment retransmits the data block to be sent, the network equipment can choose should with transmission for the first time The different priority division mode of the priority division mode used when data block to be sent, to the ratio to be sent when retransmitting At least one bit field that spy includes carries out priority division.For example, transmitting the data block to be sent for the first time corresponds to L First bit to be sent retransmits corresponding L the second bit to be sent when the data block to be sent, wherein L first to Sending bit and L the second bits to be sent includes information bits field S, the first check bit field P1 and the second school Bit field P2 is tested, if determining L the first bit packets to be sent using second of priority division mode when transmitting for the first time The priority of at least one bit field included, that is, the priority of information bits field S is higher than the first check bit field P1 Priority, and the priority of the first check bit field P1 be higher than the second check bit field P2 priority.Then, in weight When biography, the network equipment need to using a kind of priority division mode in addition to second of priority division mode, to L second to It sends bit and carries out the priority division of bit field, for example, the 7th kind of priority division mode can be used, thus, in weight When biography, the priority of the first check bit field P1 is higher than the priority of information bits field S, and information bits field S's is excellent First grade is higher than the priority of the second check bit field P2.
It should be noted that L the first bits to be sent can be identical with L the second bits to be sent, it can portion Split-phase is same, can also be entirely different.In addition, transmitting the number of corresponding bit to be sent when the data block to be sent for the first time It may be the same or different with the number of bit to be sent corresponding when retransmitting the data block to be sent.For example, for the first time 16 bits to be sent have been determined when transmitting the data block to be sent, have only been determined 12 when retransmitting the data block to be sent A bit to be sent.
Second: when the network equipment retransmits the data block to be sent, the network equipment can choose to be retransmitted with last The different priority division mode of the priority division mode used when the data block to be sent, when to this re-transmission to It sends at least one bit field that bit includes and carries out priority division.For example, retransmitting the data block to be sent for the second time When correspond to L third bit to be sent, retransmit corresponding L the 4th bit to be sent when the data block to be sent for the third time, Wherein, L third bit to be sent and L the 4th bits to be sent include information bits field S, the first check bit word Section P1 and the second check bit field P2, if determining L using second of priority division mode when retransmitting for second The priority at least one bit field that third bit to be sent includes；It is excellent using removing second then when third time retransmits A kind of priority division mode outside first grade division mode, the priority for carrying out bit field to L the 4th bit to be sent are drawn Point.
It should be noted that L third bit to be sent can be identical with L the 4th bits to be sent, it can portion Split-phase is same, can also be entirely different.In addition, retransmitting of corresponding bit to be sent when the data block to be sent for the second time Number may be the same or different with the number of bit to be sent corresponding when retransmitting the data block to be sent for the third time.Example Such as, 16 bits to be sent have been determined when retransmitting the data block to be sent for the second time, have retransmitted the data to be sent for the third time 12 bits to be sent have only been determined when block.
In addition, when due to transmitting data block to be sent every time, at least one bit that the bit to be sent determined includes Field can be different, for example, determining L1 bits to be sent include the verification of information bits field S and first when transmitting for the first time Bit field P1, when retransmitting for the first time, determining L2 bits to be sent include information bits field S, the first check bit word Section P1 and the second check bit field P2.At this point, if the priority division mode that uses is the first when transmitting for the first time, the The priority division mode used when primary re-transmission is second, although two kinds of priority division modes are different, two When secondary transmission, the priority of information bits field S and the first check bit field P1 are identical, reduce so as to be unable to reach The effect of bit error rate when data are transmitted in wireless communication system, therefore, the network equipment can be come by a preset rules Determine the priority division mode used when retransmitting.
The preset rules can have the following two kinds:
The first preset rules: when guaranteeing previous transmission and rear transmission, the priority of specific bit field is different.It should Specific bit field can be a bit field or multiple bit fields.For example, specific bit field is information ratio Special field S, then, and in previous transmission, such as transmission or preceding primary re-transmission for the first time, using the first priority division mode, According to the preset rules, in rear transmission, such as retransmit for the first time or it is rear it is primary retransmit, then can only select the 4th to the One of seven kinds of priority division modes.When specific bit field is multiple bit fields, such as specific bit word Section is information bits field and the first check bit field, the specific implementation process and specific bit field of the preset rules Identical when for a bit field, details are not described herein.
Second of preset rules: when guaranteeing previous transmission and rear transmission, the priority of identical bit field is different.Example Such as, previous transmission and the bit field of rear transmission are information bits field S, the first check bit field P1 and second Check bit field P2.In previous transmission, such as transmission or preceding primary re-transmission for the first time, it is divided using second of priority Mode, according to the preset rules, when transmitting for rear time, such as re-transmission for the first time or rear primary re-transmission, in order to guarantee information ratio The priority of special field S, the first check bit field P1 and the second check bit field P2 change, then can only select Select one of the 5th kind of priority division mode and the 6th kind of priority division mode.

Specific mapping process is as follows:
The L bits to be sent that the network equipment determines are b0,b1,...,bL-1, modulation symbol c0,c1,...,cLC-1, In, ciRepresent a modulation symbol (I0(i)Q0(i)…ILm-1(i)QLm-1(i)), i=0,1 ..., LC-1, LC are L pending Send the symbol numbers of bit mapped modulation symbol, whereinOm is order of modulation, for example, The order of modulation Om of QPSK, 16QAM, 64QAM, 256QAM are 2,4,6,8 respectively.For example, as L=12, using 64QAM tune When symbol processed, L bits to be sent need to be mapped to 12/6=2 64QAM modulation symbol；When using 16QAM modulation symbol, L A bit to be sent needs to be mapped to 12/4=3 16QAM modulation symbol.
In the following description, with L bits to be sent include information bits field S, the first check bit field P1 with And second check bit field P2, information bits field S priority be higher than the first check bit field P1 priority, with And first check bit field P1 priority be higher than the second check bit field P2 priority, L=12, and use 64QAM It is illustrated for modulation symbol.
When due to L=12, according toIt is found that the 64QAM modulation symbol for mapping is respectively as follows:
(I0(0)Q0(0)I1(0)Q1(0)I2(0)Q2And (I (0))0(1)Q0(1)I1(1)Q1(1)I2(1)Q2(1)), In, bit position I0(0)、 Q0(0)、I0(1)、Q0(1) reliability step is the first reliability, bit position I1(0)、Q1 (0)、I1(1)、Q1(1) reliability step is the second reliability, bit position I2(0)、Q2(0)、I2(1)、Q2(1) reliable Property grade be third reliability.
If in 12 bits to be sent, bit b0-b3 is information bits field, bit b4-b7 is the first check bit word Section and bit b8-b11 are the second check bit field, then bit b0-b3 are sequentially mapped to bit position I0(0)、Q0 (0)、 I0(1)、Q0(1) on, bit b4-b7 is sequentially mapped to bit position I1(0)、Q1(0)、I1(1)、Q1(1) on, will compare Special b8-b11 is sequentially mapped to bit position I2(0)、Q2(0)、I2(1)、Q2(1), as illustrated in fig. 12.Alternatively, by bit b0- B3 is sequentially mapped to bit position I0(0)、I0(1)、Q0(0)、Q0(1) on, bit b4-b7 is sequentially mapped to bit position I1 (0)、I1(1)、 Q1(0)、Q1(1) on, bit b8-b11 is sequentially mapped to bit position I2(0)、I2(1)、Q2(0)、Q2(1), As shown in Figure 12 B.
If in 12 bits to be sent, bit b0-b5 is information bits field, bit b6-b7 is the first check bit word Section and bit b8-b11 are the second check bit field, since the bit position of the first reliability only includes I0(0)、Q0(0)、 I0(1)、 Q0(1) 4 bit position, at this point, being then only second to any two bit map in bit b0-b5 to reliability step On two bit positions of the first reliability, for example, can be by two bit maps of b4, b5 to reliability step second can By the bit position I of property1(0)、Q1It (0) can also be the second reliability by two bit maps of b0, b1 to reliability step on Bit position I1(1)、Q1(1) on.For example, bit b0-b5 is sequentially mapped to bit position I0(0)、Q0(0)、I0(1)、Q0 (1)、 I1(0)、Q1(0) on, bit b6-b7 is sequentially mapped to bit position I1(1)、Q1(1) on, bit b8-b11 successively maps To bit position I2(0)、Q2(0)、I2(1)、Q2(1), as illustrated in fig. 12.Alternatively, bit b0-b5 is sequentially mapped to bit Position I0(0)、I0(1)、Q0(0)、Q0(1)、I1(0)、I1(1) on, bit b6-b7 is sequentially mapped to bit position Q1(0)、Q1 (1) on, bit b8-b11 is sequentially mapped to bit position I2(0)、I2(1)、Q2(0)、Q2(1), as shown in Figure 12 B.
If in 12 bits to be sent, bit b0, b1 are information bits field, bit b2-b7 is the first check bit word Section and bit b8-b11 are the second check bit field, and since the bit number of the first priority is only 2, and first is reliable Property bit position include 4, at this point, priority is then only second in the bit b3-b7 of the first priority any two ratio Spy is mapped on two bit positions of the first reliability, for example, can be by two bit maps of b3, b4 to reliability step For the bit position I of the first reliability1(0)、Q1It (0) can also be the by two bit maps of b0, b1 to reliability step on The bit position I of two reliabilities1(1)、Q1(1) on.For example, bit b0, b1 are sequentially mapped to bit position I0(0)、Q0(0) On, bit b2-b7 is sequentially mapped to bit position I0(1)、Q0(1)、I1(0)、Q1(0)、I1(1)、Q1(1) on, bit b8-b11 It is sequentially mapped to bit position I2(0)、Q2(0)、I2(1)、Q2(1), as illustrated in fig. 12.Alternatively, bit b0, b1 are successively reflected It is mapped to bit position I0(0)、I0(1), on, bit b2-b7 is sequentially mapped to bit position Q0(0)、Q0(1)、I1(0)、 I1(1)、 Q1(0)、Q1(1) on, bit b8-b11 is sequentially mapped to bit position I2(0)、I2(1)、Q2(0)、Q2(1), as shown in Figure 12 B.
In this way, the network equipment when transmitting data block to be sent for the first time, the priority of information bits field can be set It is set to highest priority, it, can be with thus by the bit map in information bits field to the high bit position of reliability step Reduce the bit error rate of information bits field；When retransmitting, it is preferential highest can be set by the priority for verifying bit field Grade reduces the bit error rate of check bit field, it is possible to reduce the number of re-transmission reduces time delay, to improve wireless communication system Transmission performance.
In embodiments of the present invention, in order to further decrease bit error rate when data in wireless communication system are transmitted, network Equipment can be by two kinds of preset rules above-mentioned, come the priority division mode used when determining re-transmission, naturally it is also possible to adopt Determine that the priority division mode used when retransmitting, the application do not limit this with other rules or mode.In order to say Influence of the bright two kinds of preset rules above-mentioned to mapping process, it is pre- using the first for please referring to Figure 13 A and Figure 13 B, Figure 13 A If influence of the rule to mapping process, Figure 13 B is the influence using second of preset rules to mapping process.Wherein, Figure 13 A The L bits to be sent with previous transmission in Figure 13 B and rear transmission are including information bits field S, the first check bit Field P1 and the second check bit field P2, L=24, wherein information bits field S, the first check bit field P1 and The number of bits of second check bit field P2 is 8, and is all made of 64QAM modulation symbol and is mapped.
In figure 13a, when previous transmission, information bits field S, the first check bit field P1 and the second check bit Field P2 is sequentially mapped to the bit position of the first reliability of modulation symbol, the bit position of the second reliability and third can By the bit position of property；In rear transmission, guarantee the reliability step for the bit position that information bits field S is mapped to not Become, using the third priority division mode, so that the first check bit field P1 to be mapped to the bit of third reliability It sets, the second check bit field P2 is mapped to the bit position of the second reliability.
In Figure 13 B, when previous transmission, information bits field S, the first check bit field P1 and the second check bit Field P2 is sequentially mapped to the bit position of the first reliability of modulation symbol, the bit position of the second reliability and third can By the bit position of property；In rear transmission, guarantee information bits field S, the first check bit field P1 and the second verification The reliability step for the bit position that bit field P2 is mapped to is all different, using the 6th kind of priority division mode, thus Information bits field S is mapped to the bit position of the second reliability, it is reliable that the first check bit field P1 is mapped to third Second check bit field P2, is mapped to the bit position of the first reliability by the bit position of property.
It should be noted that the mapping mode of Figure 13 A and Figure 13 B only are used to illustrate the data processing side of the embodiment of the present invention A kind of specific embodiment of method, those skilled in the art can also use other specific embodiments, and this is not restricted.
It in one possible implementation, further include step 506 before step 505: by the L ratios to be sent Spy is ranked up according to the sequence of priority from high to low.
After the priority that the network equipment determines each bit field that L bits to be sent include, the network equipment is then L bits to be sent are ranked up, the high bit field of priority is arranged in front of the low bit field of priority.Example Such as, the network equipment obtains the bits to be sent of L shown in Fig. 9 B, and the sequence of the bit field of L bits to be sent is followed successively by the Two verification bit field P2, information bits field S and the first check bit field P1, the network equipment are preferential using second Grade division mode determines that the priority of information bits field S is higher than the priority of the first check bit field P1, and the first school The priority for testing bit field P1 is higher than the priority of the second check bit field P2, at this point, the network equipment is then pending by L It send bit to be ranked up, obtains L as shown in Figure 10 bits to be sent.
Then, the network equipment then according to the method for step 505 by L as shown in Figure 10 bit maps to be sent to modulating On L bit position of symbol, details are not described herein.
It should be noted that above-mentioned steps 506 are optional steps, i.e., the network equipment is ranked up L bits to be sent It is optional process, it is not necessary to which execution, the network equipment can not be to the L ratios to be sent after obtaining L bits to be sent Spy is ranked up, just directly will be in L bit maps to be sent to L bit position of modulation symbol.
Step 507: the modulation symbol after output mapping.
After the network equipment is by L bit maps to be sent to L bit position of modulation symbol, then mapped Modulation symbol afterwards.For example, being obtained after on 12 bit positions of 12 bit maps to be sent to 64QAM modulation symbol 64QAM modulation symbol to after 2 mappings；By 12 bit positions of 12 bit maps to be sent to 16QAM modulation symbol 64QAM modulation symbol after upper, after obtaining 3 mappings.In actual use, those skilled in the art can be according to nothing The specific requirement of line communication system selects suitable modulation system.For example, if the more demanding spectrum utilization of wireless communication system Rate then can choose 64QAM modulation system；If wireless communication system requires the lower bit error rate, 16QAM tune can choose Mode processed just different one schematically illustrates herein.
Step 508: processing being interleaved to the modulation symbol after mapping using block interleaving mode, after generating interleaving treatment Modulation symbol.
In order to improve the error correcting capability of wireless communication system, the network equipment may be used also after the modulation symbol after being mapped To carry out block interleaving processing to the modulation symbol after mapping.In embodiments of the present invention, the interleaver matrix in the block interleaving mode Line number and columns in a parameter it is true according to the length of time scheduling unit and/or the symbol quantity of the modulation symbol It is fixed.
Specifically, the line number of interleaver matrix or the method for determination of columns can use following three kinds of modes:
First way:
The line number or columns of interleaver matrix are the subduplicate integer closest to the symbol quantity of modulation symbol, that is, are interweaved The line number of matrix or the value of columns are equal toWherein, f (t)=t orOrT is indicated Parameter in function, LCFor symbol numbers needed for L bits to be sent of modulation.For example, working as LCWhen=12, then the row of interleaver matrix Several or columns is equal to
The second way:
The line number or columns of interleaver matrix are equal to the length of time scheduling unit, wherein the length of time scheduling unit is used Included indicates for sending the OFDM symbol number of the data block to be sent.For example, a slot includes 6 OFDM symbol, then the line number of interleaver matrix or columns are 6.
The third mode:
The line number or columns of interleaver matrix are the length closest to the symbol quantity and time scheduling unit of modulation symbol The integer of ratio.That is, the line number of interleaver matrix or the value of columns are equal toWherein, f (t)=t or OrParameter in t representative function, Ns are the length of time scheduling unit, the use for being included with time thread It is indicated in the OFDM symbol number for sending the data block to be sent.For example, working as LC=12, a slot includes 6 OFDM Symbol, then the line number or columns of interleaver matrix, are equal to f (12/6)=2.
It should be noted that the network equipment can send the multiple groups generated by multiple groups data block to be sent in synchronization L bits to be sent, at this point, for determining the symbol quantity of the line number of interleaver matrix or the modulation symbol of columns are as follows: by multiple groups The total quantity of modulation symbol needed for bit position in L bit maps to modulation symbol to be sent.For example, by two groups In the two groups of L bits to be sent that data block to be sent generates, by first group of L of first group of data block generation to be sent The number of bits L=12 of a bit to be sent, the second group of L bits to be sent generated by second group of data block to be sent Number of bits L=12, then the total quantity LC=3+3=of the 16QAM modulation symbol arrived two groups of L bit maps to be sent 6；Or, the number of bits L=24 of the first group of L bits to be sent generated by first group of data block to be sent, by second group The number of bits L=36 for the second group of L bits to be sent that data block to be sent generates, then by two groups of L bits to be sent The total quantity LC=6+9=15 for the 16QAM modulation symbol being mapped to.
After the network equipment determines line number or the columns of interleaver matrix, then according to the interleaver matrix to LCA modulation symbol into Row block interleaving treatment.It should be noted that LCIt can be most with modulation symbol when a modulation symbol carries out block interleaving processing Small processing unit can also be interleaved processing using the bit in modulation symbol as minimal processing unit, implement in the present invention In example with no restriction.
It is minimal processing unit to L using modulation symbolCFor a modulation symbol carries out block interleaving processing, the network equipment is determined By one group of L bit maps to be sent to LCAfter a modulation symbol, for example, LC=16, respectively C0、C1…C15, using by row The mode of write-in obtains interleaver matrix as shown in figure 14, at this point, interleaver matrix one shares 16 elements, line number and columns It is 4.Using by the modulation symbol after column playback mode acquisition interleaving treatment, it is followed successively by C0、C4、C8、C12、C1、 C5、C9、C13、 C2、C6、C10、C14、C3、C7、C11、C15, as shown in figure 15.Then by C0、C4、C8、 C12It is output to the four of first OFDM symbol On a subcarrier, by C1、C5、C9、C13It is output on four subcarriers of second OFDM symbol, by C2、C6、C10、C14Output Onto four subcarriers of third OFDM symbol, by C3、C7、C11、C15It is output to four subcarriers of the 4th OFDM symbol On, to obtain 4 OFDM symbols, successively transmitting this 4 respectively at the time of 4 differences includes four subcarriers OFDM symbol.
If the network equipment sends the two groups of L bits pair to be sent generated by two groups of data blocks to be sent in synchronization The two groups of modulation symbols answered, wherein first group of modulation symbol is C0、C1、C2、C3、C4、C5、C6、C7, second group of modulation symbol be C′0、C′1、C′2、C′3、C′4、C′5、C′6、C′7, this two groups of modulation symbols alternately are read in by the way of entering by row write at this time, are obtained Interleaver matrix as shown in figure 16 is obtained, which shares 16 elements, and line number and columns are 4.It is read using by column Mode obtains the modulation symbol after interleaving treatment out, is followed successively by C0、C′0、C4、C′4、C′1、C′1、C5、C′5、 C2、C′2、C6、C′6、 C3、C′3、C7、C′7, as shown in figure 17.Then by C0、C′0、C4、C′4It is output to ' four son load ' the wave of first OFDM symbol On, by C '1、C1、C5、C5It is output on four subcarriers of second OFDM symbol, by C2、C′2、C6、C′6It is output to third On four subcarriers of OFDM symbol, by C3、C′3、C7、C′7It is output on four subcarriers of the 4th OFDM symbol, thus Obtain 4 OFDM symbols, successively transmitted respectively at the time of 4 differences this 4 include four subcarriers OFDM symbol.
In one possible implementation, if the L that L bit maps to be sent arriveCThe number of a modulation symbol can not A complete interleaver matrix is constituted, for example, LC=14, as shown in figure 18, at this point, then most latter two yuan in interleaver matrix Element is sky, using by the column playback mode acquisition modulation symbol that is interleaved that treated, is followed successively by C0、C4、C8、C12、C1、 C5、 C9、C13、C2、C6、C10, empty, C3、C7、C11, it is empty.Then by C0、C4、C8、C12Four sons for being output to first OFDM symbol carry On wave, by C1、C5、C9、C13It is output on four subcarriers of second OFDM symbol, by C2、C6、C10It is output to third On three subcarriers of OFDM symbol, by C3、C7、C11It is output on three subcarriers of the 4th OFDM symbol, to obtain 4 OFDM symbols, and successively at the time of 4 differences on transmit this 4 OFDM symbols respectively.
It should be noted that step 501- step 504, step 506 and step 508 are optional steps, it is not necessary to hold Capable.Known while i.e. the network equipment reads L bit to be sent it includes bit field priority, thus On the bit position for the modulation symbol that the bit priority in the high bit field of priority is directly mapped to high reliablity, most After export the modulation symbol.
Using data processing method provided in an embodiment of the present invention, pass through each bit field distribution for bit to be sent Bit field with different priority is respectively mapped to the different bit positions of modulation symbol by suitable priority On, there is the characteristic of different reliability steps, preferential improve data transfer mistake in different bit positions in conjunction with modulation symbol The transmission reliability of significant data in journey, to realize the promotion of the transmission performance of wireless communication system.
