Specific embodiment
To make the objectives, technical solutions, and advantages of the present invention clearer, below in conjunction with attached drawing to the present invention make into It is described in detail to one step, it is clear that the described embodiments are only some of the embodiments of the present invention, rather than whole implementation Example.Based on the embodiments of the present invention, obtained by those of ordinary skill in the art without making creative efforts All other embodiment, shall fall within the protection scope of the present invention.
In the embodiment of the present invention when carrying out data transmission, transmitting terminal chooses an at least column code from multiple access codebook set This, for any one column code book of selection, according to the corresponding dimension of the column code book of selection, from the multi-dimensional constellation atlas The corresponding planisphere of the dimension is determined in conjunction；The transmitting terminal is sent by the resource of the corresponding planisphere mapping of the dimension Data, receiving end determines at least one column in multiple access codebook set, and is directed to any one column code book of selection, according to the institute of selection The corresponding dimension of a column code book is stated, the corresponding planisphere of the dimension, the transmission are determined from the multi-dimensional constellation set of graphs End sends data by the resource of the corresponding planisphere mapping of the dimension.Since in present invention implementation, multiple access pattern set is By for indicating that the resource impact pattern matrix of position that modulation symbol occurs in the resource of distribution determines, therefore formed more Location pattern set is that not equal column weigh, then by not waiting column weight multiple access pattern set and multi-dimensional constellation diagram to determine receiving end and hair The multiple access codebook set of sending end, so that the order of diversity of different terminals is different, to improve demodulation performance.
The method of data transmission is described in detail in the embodiment of the present invention below.
In embodiments of the present invention, multiple access codebook set is determined by multi-dimensional constellation set of graphs and multiple access pattern set, therefore Firstly the need of determining multiple access pattern set and multi-dimensional constellation set of graphs.
The embodiment of the present invention provides a kind of method of determining multiple access pattern set, in an implementation:
For example, resource impact pattern matrix S (4 rows 15 column) is as follows at this time when the number of resources of 15 terminals is 4:
It can be seen that there are " 1 " and " 0 " two kinds of representations from matrix S, wherein " 1 " in matrix S indicates modulation symbol Number in the position for occupying resource, " 0 " indicates that modulation symbol will not occupy the position of resource, when modulation symbol occupies 4 resources, Modulation symbol only has when occupying position (the having 4 " 1 ") of resourceThis kind of situation, when modulation symbol occupies 3 resources When, modulation symbol has when occupying position (the having 3 " 1 ") of resourceWithThese four situations, work as tune When symbol processed occupies 2 resources, modulation symbol has when occupying position (there are 2 " 1 ") of resource WithThis six kinds of situations, when modulation symbol occupies 1 resource, modulation symbol occupies money The position (there are 1 " 1 ") in source hasWithModulation symbol may occupied resource by these four situations Position the case where it is unified into a set S, so that it may obtain the resource impact pattern matrix S.
From the example above it is found that when the value difference of number of resources N, modulation symbol occupies the feelings that the position of resource occurs Condition is also different, and then matrix S is also different, but no matter the value of N be it is several, modulation symbol occupy resource when there is how many kinds of Situation, matrix S can embody all arrangement modes.
Based on this, modulation symbol can be constructed according to the various arrangement mode that modulation symbol occupies resource location and arrive resource Resource impact pattern matrix, for example when number of resources is N, then the various arrangement mode structure of resource location is occupied according to modulation symbol It is as follows to make the resource impact pattern matrix S that modulation symbol arrives:
Wherein, the number that " 1 " occurs in each column of i representing matrix S, the line number of matrix S are determined by number of resources N, and The method of salary distribution of resource includes but is not limited to some or all of in following manner:
It is pre-configured with distribution resource, half dynamic allocation of resources or dynamic allocation of resources.
Wherein, be pre-configured with (i.e. static configuration) here is referred to by RRC (Radio Resource Control, nothing Line resources control) signal the resource of distribution；Half dynamic allocation of resources is referred to by MAC-CE (MAC Control Element, Medium Access Layer control unit) signal the resource of distribution；Half dynamic allocation of resources refers to being led to by L1 signaling Know the resource of distribution, for example can be DCI (Downlink Control Information, Downlink Control Information)/UCI (Uplink Control Information, ascending control information) signaling.
Resource in the embodiment of the present invention can be physical resource or virtual resource.
When the resource is physical resource, resource can be Time domain physical resource or frequency-domain physical resource；When the money When source is virtual resource, after different terminals carry out multiple access pretreatment, need that virtual resource is mapped to object by certain mode It manages in resource, for example virtual resource is mapped on physical resource by the way of the public interleaving treatment of cell.
Correspondingly, going out resource mapping pattern matrix when occupying all placement configurations being likely to occur of resource according to modulation symbol Later, to be used at least one is needed when determining that terminal sends data from the resource impact pattern matrix of construction according to the resource of terminal A multiple access pattern set.
For example, determining from resource impact pattern matrix and being used when sending data when the resource of 15 terminals is 4 resources A multiple access pattern set it is as follows:
Here multiple access pattern set is 4 rows 15 column chosen from resource impact pattern matrix, contains modulation symbol All positions being likely to occur when resource are occupied, for example all positions being likely to occur only have when modulation symbol 4 resources of occupancy First row.
In embodiments of the present invention, it is determined due to multiple access codebook set by multi-dimensional constellation set of graphs and multiple access pattern set, Therefore it after determining multiple access pattern set, also needs to determine multi-dimensional constellation set of graphs.
Wherein, planisphere as shown in Figure 2 is the distribution map of signal phasor endpoint, it is generally the case that can use planisphere The signal space distribution of M-QAM signal is described, by the optimization design to M-QAM signal constellation (in digital modulation) figure, available property The different M-QAM modulation scheme of energy.
MQAM signal constellation (in digital modulation) figure has star constellation, uneven star constellation and square constellation three categories type.
Here multi-dimensional constellation set of graphs is under the premise of given dimension D, includes M star under the constraint condition for estimating m The multi-dimensional constellation set of graphs of seat point, and m maximization is estimated between the constellation point in multi-dimensional constellation set of graphs.Wherein, described more The generation of certain dimension planisphere can be obtained by solving following optimization problem in dimension planisphere:
Wherein G indicates certain dimension planisphere in multi-dimensional constellation set of graphs, includes in D expression multi-dimensional constellation set of graphs The maximum latitude of planisphere, M indicate the number of multi-dimensional constellation set of graphs culminant star seat point, i-th of constellation in multi-dimensional constellation set of graphs Point is expressed as gi。
It is described to estimate m and can be under certain channel, the mutual trust between the multi-dimensional constellation set of graphs of transmitting terminal and receiving end The product isometry of the Euclidean distance of breath or various constellations point between any two, any can satisfy estimate maximized quantization Parameter all can serve as to estimate, and given dimension D refers to the maximum dimension for the planisphere for including in multi-dimensional constellation set of graphs.
As shown in figure 3, such as: when the product estimated m and be defined as the Euclidean distance of various constellations point between any two, and And the maximum dimension D=3 of multi-dimensional constellation set of graphs, (i.e. order of modulation is the number M=4 of multi-dimensional constellation set of graphs culminant star seat point log2M=2), multi-dimensional constellation diagram at this timeFor D=33 dimension planisphere (sk (d)=αk (d)exp(jθk (d))=ak (d)+jbk (d) Middle imaginary part is 0, i.e. bk (d)=0).It is available by solving above-mentioned optimization problem and after known above-mentioned configuration parameter 3 dimension planispheresIn 4 QPSK (Quadrature Phase Shift Keyin, quadrature phase shift keying) modulation constellation point It is respectively as follows: p1=(0.5, -0.5,0.5), p2=(- 0.5,0.5,0.5), p3=(0.5,0.5, -0.5), p4=(- 0.5, - 0.5, -0.5), specific location is shown in Figure 3.
What needs to be explained here is that multi-dimensional constellation set of graphs include multiple dimension planispheres, such as comprising two dimensional constellation figure, Three-dimensional constellation map, four-dimensional planisphere ... .., if maximum dimension is eight, until octuple constellation since two dimensional constellation figure Figure.
What needs to be explained here is that: since multiple access pattern set is the resource N according to distribution and the terminal base using resource It is determined in resource impact pattern matrix, and the first multi-dimensional constellation in the embodiment of the present invention only needs to meet and estimates m maximization , it can be seen that multiple access pattern set and multi-dimensional constellation set of graphs in the embodiment of the present invention do not have any association, therefore Multiple access pattern set and multi-dimensional constellation set of graphs are all independent designs.
The embodiment of the present invention can generate multiple access codebook set according to above-mentioned multi-dimensional constellation set of graphs and multiple access pattern set.
In an implementation, it is thus necessary to determine that the number of multiple access pattern set row and column, it later can be according to modulation system from multidimensional The constellation point that multiple access pattern set includes is determined in constellation point in planisphere set including different dimensions, and according to multiple access pattern The constellation point that set includes determines the code word of each column in multiple access pattern set, wherein there are multidimensional stars for multi-dimensional constellation set of graphs Combine on seat figure and determines that the mode of each column code word or two dimensional constellation figure determine every in multiple access pattern set in multiple access pattern set The mode of one column code word.
For example, including not from multi-dimensional constellation set of graphs according to multidimensional M-QAM modulation when using multidimensional M-QAM modulation It, can be using Gray or non-gray mapping after determining constellation point that multiple access pattern set includes in the constellation point of dimension Mode, the constellation point of each column code word from a bit map multiple access pattern set of m=log2 (M), gray mappings here are just It is the corresponding m bit of the adjacent constellation point of any two, has and only 1 bit is different.
Wherein, the modulation system of use is not limited solely to multidimensional M-QAM modulation system, can also be QPSK, 16QAM, The modulation systems such as 64QAM.
Since there are combine the mode or two dimension that determine a constellation point sets in multi-dimensional constellation diagram for multi-dimensional constellation set of graphs Planisphere determines the mode of a constellation point sets, therefore the multiple access codebook set generated is different.
When multi-dimensional constellation set of graphs is to combine the mode for determining a constellation point sets in multi-dimensional constellation diagram, generation The coordinate points of each column code book in multiple access codebook set are not identical, when multi-dimensional constellation set of graphs is combined on two dimensional constellation figure When determining the mode of a constellation point sets, the coordinate points of each column code book in the multiple access codebook set of generation are identical.
It further explains how to carry out multiple access codebook set according to the above method below by specific embodiment:
Embodiment 1: the multiple access codebook set generated by the duplicate mode of two dimensional constellation figure:
As shown in figure 4, when by taking the resource for 15 terminal distributions is 4 resources as an example:
Step 400 obtains N row (being originally embodied as 4 rows 15 column) according to the numerical value of N in resource impact pattern matrix S first Acquisition forms multiple access pattern set；
Step 401 determines that multiple access pattern set includes from the constellation point for the two-dimensions for including in multi-dimensional constellation set of graphs Constellation point；
Step 402 determines each column in multiple access pattern set according to the two-dimensions constellation point for including in multiple access pattern set Code word, the multiple access codebook set of formation at this time is as follows:
Wherein, the specific coordinate points of code word of each column in multiple access codebook set are by sk=αk exp(jθk)=ak+jbk It determines, θkIndicate angle, αkExpression amplitude, akIndicate real part coefficient, bkIndicate imaginary part coefficient.
Since the constellation point of code book in multiple access codebook set is determined by two-dimensions planisphere in multi-dimensional constellation set of graphs, Therefore it is identical that the position that modulation symbol occupies resource in each column code book in multiple access codebook set, which obtains coordinate points all,.
For example, it is the first row, the second row and the third line, therefore, that modulation symbol, which occupies the position of resource, in third column The code book coordinate of the first row, the second row and the third line in three column is s3=α3exp(jθ3)=a3+jb3。
Embodiment 2: combine the multiple access codebook set for determining that a constellation point sets generate in multi-dimensional constellation diagram:
As shown in figure 5, when in case where being multiplexed 15 users in 4 resources:
Step 500 obtains N row (be originally embodied as 4 rows 15 column) according to the numerical value of N in resource impact pattern matrix S and obtains 4 The column of row 15 form multiple access pattern set；
Step 501 determines that multiple access pattern set includes from the constellation point for the various dimensions for including in multi-dimensional constellation set of graphs Constellation point；
Step 502, determined according to the constellation point for the various dimensions for including in multiple access pattern set it is each in multiple access pattern set The code word of column, the multiple access codebook set formed at this time are as follows:
Wherein, the specific coordinate points of code word of each column in multiple access codebook set are by sk (d)=αk (d)exp(jθk (d))= ak (d)+jbk (d)It determines, θk (d)Indicate angle, αk (d)Expression amplitude, ak (d)Indicate real part coefficient, bk (d)Indicate imaginary part coefficient.
Since the constellation point of code book in multiple access codebook set is determined by the various dimensions planisphere in multi-dimensional constellation set of graphs , therefore it is not identical that the position that modulation symbol occupies resource in each column code book in multiple access codebook set, which obtains coordinate points all, 's.
For example, it is the first row, the second row and the third line, therefore, that modulation symbol, which occupies the position of resource, in third column The code book coordinate of the first row in three column is s3 (1)=α3 (1)exp(jθ3 (1))=a3 (1)+jb3 (1), the second row code book coordinate be s3 (2)=α3 (2)exp(jθ3 (2))=a3 (2)+jb3 (2), the third line code book coordinate be s3 (3)=α3 (3)exp(jθ3 (3))=a3 (3)+jb3 (3)。
Correspondingly, after completing multiple access codebook set, by the binding relationship of multiple access codebook set and modulation system and more Location codebook set is pre-configured in transmitting terminal and receiving end and transmits for data.
Based on this, as shown in fig. 6, the embodiment of the present invention provides a kind of system of data transmission, which includes:
Transmitting terminal 600, for choosing an at least column code book from the current corresponding multiple access codebook set of modulation system, Described in multiple access codebook set determine that the multiple access pattern set is by resource by multi-dimensional constellation set of graphs and multiple access pattern set Mapping pattern matrix determines that the resource impact pattern matrix is for indicating the position that modulation symbol occurs in the resource of distribution Various arrangement mode；It include the planisphere of multiple and different dimensions in multi-dimensional constellation set of graphs；For any one column code of selection This, transmitting terminal determines that the dimension is corresponding from multi-dimensional constellation set of graphs according to the corresponding dimension of the column code book of selection Planisphere；Transmitting terminal sends data by the resource of the corresponding planisphere mapping of the dimension.
Receiving end 601, for determining at least column code book in the corresponding multiple access codebook set of current modulation system；Its Described in multiple access codebook set determine that the multiple access pattern set is by resource by multi-dimensional constellation set of graphs and multiple access pattern set Mapping pattern matrix determines that the resource impact pattern matrix is for indicating the position that modulation symbol occurs in the resource of distribution Various arrangement mode；It include the planisphere of multiple and different dimensions for any one column code book, in multi-dimensional constellation set of graphs；For Any one column code book of selection, the transmitting terminal is according to the corresponding dimension of the column code book of selection, from multi-dimensional constellation atlas The corresponding planisphere of the dimension is determined in conjunction；Receiving end sends number by the resource of the corresponding planisphere mapping of the dimension According to.
When needing to transmit data, transmitting terminal is according to preconfigured current modulation system, multi-dimensional constellation diagram and more Location pattern set determines multiple access codebook set.Then an at least column code book is chosen from multiple access codebook set.Wherein, multiple access figure It is determined when sample set according to the position that modulation symbol occurs in resource, the specific method for determining multiple access codebook set is above-mentioned The method for determining multiple access codebook set, details are not described herein again.
But when transmitting terminal is terminal, in transmitting terminal according to the position determination that modulation symbol occurs in resource Before multiple access pattern set, it is also necessary to receive the position that the modulation symbol of network side equipment notice occurs in resource, Zhi Houzai Multiple access pattern set is determined according to the position occurred in resource.
Wherein, network side equipment notifies end modification symbol at the position occurred in resource, needs according to different terminals Actual modulation symbol and resource situation distribution, for example the position that occurs in resource of modulation symbol of terminal A is a, terminal B's The position that modulation symbol occurs in resource is b.When the position that network side equipment notice end modification symbol occurs in resource When, that notice terminal A is a, and that notice terminal B is b.
Correspondingly, transmitting terminal is after choosing an at least column code book in multiple access codebook set, in selected code book The corresponding dimension of an at least column code book is chosen, the corresponding planisphere of the dimension is determined from multi-dimensional constellation set of graphs, and send End sends data by the resource of the corresponding planisphere mapping of the dimension.
In an implementation, the dimension of multi-dimensional constellation diagram used in each terminal be by from this set of multiple access code that What column code book determined, i.e., the dimension of k-th planisphere used by a user is by multiple access codebook setIt determines.Than Such as, as shown in fig. 7, transmitting terminal is according to current multiple access codebook set are as follows:
3rd terminal is the 3rd column code book in multiple access codebook setThen transmitting terminal is determined according to the 3rd column code book The dimension of planisphere used in the 3rd terminal is 6 dimensions out.
After sending the dimension for determining multi-dimensional constellation diagram used in the 3rd terminal is 6 dimension, from preconfigured multidimensional star The corresponding planisphere of dimension is determined in seat set of graphs, and data are sent by the resource of the corresponding planisphere mapping of dimension again later.
For example, as shown in figure 3, if transmitting terminal according to the 3rd column code book determine the 3rd terminal used in multi-dimensional constellation diagram Dimension be 3 dimensions, at this point, shown in black color dots shown in included 4 constellation point in three-dimensional constellation map is as shown in Figure 3.
It is more used in each terminal but when multiple access codebook set is generated by the duplicate mode of two dimensional constellation figure The dimension for tieing up planisphere can determine by a code book coordinate in that column code book in multiple access codebook set where itself, i.e., the The dimension of k planispheres used by a user is by the s in multiple access codebook setkDetermining.
For example, transmitting terminal is according to current multiple access codebook set are as follows:
3rd terminal is in the 3rd column code book in multiple access codebook setThen transmitting terminal is according in the 3rd column code book S3The dimension for being assured that out multi-dimensional constellation diagram used in the 3rd terminal is 2 dimensions.
When send the dimension for determining multi-dimensional constellation diagram used in the 3rd terminal be 2 dimensions after, from preconfigured more It ties up and determines the corresponding planisphere of dimension in planisphere set, number is sent by the resource of the corresponding planisphere mapping of dimension again later According to.
Wherein, transmitting terminal can also select an at least column code book from the column of the part of currently determining multiple access codebook set.
For example, the current multiple access codebook set of the transmitting terminal is 15 column, and the terminal of the data sent is needed there was only 6 People, therefore, transmitting terminal can in multiple access codebook set before 6 column in select an at least column code book.
After transmitting terminal determines the planisphere of corresponding dimension, one can also be determined from planisphere according to data to be passed A constellation point, and data are sent according to the transmission power of distribution from the resource of this determining constellation point.
Wherein, the transmission power is distributed for transmitting terminal or for resource allocation, i.e., network side equipment according to The terminal and existing resource that need to transmit data are the transmission power of transmitting terminal distribution, and the mode present invention specifically distributed is implemented Example is without limitation.
For example, network side equipment is sent according to all terminals by respective maximum transmission power by transmitting terminal or net Network side apparatus carries out constant power distribution, or can satisfy its QoS (Quality of for the terminal distribution close apart from base station Service, quality of service) require smaller power, terminal distribution relatively high power remote apart from base station etc..
But what needs to be explained here is that: when transmitting terminal is terminal, it may appear that the identical column of different terminal selections The case where code book, transmitting terminal needs the rotation optimized to the corresponding planisphere of dimension according to maximized criterion is estimated at this time Angle passes throughCarry out angle rotation, and the resource mapped from postrotational multi-dimensional constellation diagram Upper transmission data.
Likewise, also will appear network side equipment is that different terminal selections is identical when transmitting terminal is network side equipment A column code book will appear, the transmitting terminal is also required to the corresponding planisphere of different terminals dimension according to maximized quasi- at this time The rotation angle then optimized, passes throughIt is rotated, and from postrotational multi-dimensional constellation Data are sent in the resource mapped in figure.
In embodiments of the present invention, when occur transmitting terminal send data terminal select an identical column code book the case where When, angle rotation can be carried out to the corresponding planisphere of different terminals dimension, so that the planisphere of different terminals is different, thus real Present different terminals further discriminating between on planisphere, improves demodulation performance.
Correspondingly, receiving end can have two ways after transmitting terminal sends data from the resource of constellation point Receive the data, a kind of mode is which column code that transmitting terminal known to receiving end sends the multiple access codebook set chosen when data This, another way is which column code book that receiving end does not know the multiple access codebook set chosen when transmitting terminal sends data, under It is introduced in face of both modes.
One, transmitting terminal known to receiving end sends which column code book of the multiple access codebook set chosen when data:

Wherein, the multiple access pattern set is that the position occurred in resource according to modulation symbol determines.
It is true in the position that receiving end occurs in resource according to modulation symbol but when receiving end is network side equipment Before the fixed multiple access pattern set, it is also necessary to the position for notifying end modification symbol to occur in resource, later further according to money Determine multiple access pattern set in the position occurred on source.
Wherein, network side equipment notifies end modification symbol at the position occurred in resource, needs according to different terminals Actual modulation symbol and resource situation distribution, for example the position that occurs in resource of modulation symbol of terminal A is a, terminal B's The position that modulation symbol occurs in resource is b.When the position that network side equipment notice end modification symbol occurs in resource When, that notice terminal A is a, and that notice terminal B is b.
For any one column code book of selection, the receiving end determines corresponding dimension according to a column code book, from described more It ties up and determines the corresponding planisphere of the dimension in planisphere set, it is specific to determine that method is the corresponding constellation of above-mentioned determining dimension The method of figure is the same, and details are not described herein again, later again by receiving data on the corresponding planisphere of the dimension.
It, can also be true from corresponding planisphere according to data to be passed after the planisphere of corresponding dimension is determined in receiving end A fixed constellation point, and data are received according to the reception power of distribution from the resource of this determining constellation point.
Wherein, the reception power is distributed for transmitting terminal or for resource allocation, i.e., network side equipment according to The terminal and existing resource for needing to receive data are that receiving end distribution receives power, the specific method of salary distribution and transmitting terminal phase Together, it is not just repeating herein.
Two, receiving end does not know which column code book of the multiple access codebook set chosen when transmitting terminal sends data:
Receiving end determines that the modulation system is corresponding according to current modulation system, multi-dimensional constellation diagram and multiple access pattern set The multiple access codebook set, specific to determine that method is the method for above-mentioned determining multiple access codebook set, details are not described herein again.
Wherein, the multiple access pattern set is that the position occurred in resource according to modulation symbol determines.
It is true in the position that receiving end occurs in resource according to modulation symbol but when receiving end is network side equipment Before the fixed multiple access pattern set, it is also necessary to the position for notifying end modification symbol to occur in resource, later further according to money Determine multiple access pattern set in the position occurred on source.
Wherein, network side equipment notifies end modification symbol at the position occurred in resource, needs according to different terminals Actual modulation symbol and resource situation distribution, for example the position that occurs in resource of modulation symbol of terminal A is a, terminal B's The position that modulation symbol occurs in resource is b.When the position that network side equipment notice end modification symbol occurs in resource When, that notice terminal A is a, and that notice terminal B is b.
Then an at least column code book is chosen from multiple access codebook set, then chooses each column code book in multiple access codebook set It determines its corresponding dimension, the constellation scale of all corresponding dimensions is determined from multi-dimensional constellation set of graphs, by all corresponding dimensions The constellation scale of degree is compared with the constellation scale of corresponding dimension used when transmitting terminal transmission data, finds identical more After tieing up planisphere, a constellation point is determined from identical multi-dimensional constellation diagram according to data to be received；And from constellation point Data are received according to reception power in resource.
Receiving power is for transmitting terminal distribution or for resource allocation, i.e. network side equipment receives number as needed According to terminal and existing resource be receiving end distribution receive power, the specific method of salary distribution is identical as transmitting terminal, herein just not It is repeating.
There is also the need to illustrate to be, when transmitting terminal is terminal, there is different terminal and select identical column code book, send End to the corresponding planisphere of dimension carry out angle rotation the case where when, at this time receiving end be also required to the corresponding planisphere of dimension into Row angle rotation identical with transmitting terminal angle, and data are received from the resource mapped in postrotational planisphere.
Likewise, also will appear network side equipment is that different terminal selections is identical when transmitting terminal is network side equipment A column code book, the case where transmitting terminal carries out angle rotation to the corresponding planisphere of different terminals, receiving end is also required at this time Rotation identical with transmitting terminal angle, and the money mapped from postrotational multi-dimensional constellation diagram are carried out to the corresponding planisphere of dimension Data are received on source.
