A part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art
Every other embodiment obtained without making creative work, shall fall within the protection scope of the present invention.
It, can be with referring to Fig. 1, it illustrates a kind of flow chart of data transfer control method provided in an embodiment of the present invention
The following steps are included:
101: determine the corresponding PDMA matrix of resource group for being used for transmission data and each terminal using PDMA matrix,
Wherein each PDMA pattern of PDMA matrix is multiplexed same resource group, in this way can by for each terminal distribution it is corresponding
PDMA pattern transmits the data to be transmitted of each terminal, the quantity for the PDMA pattern for including for PDMA matrix, PDMA pattern
Form and multiplexing the same resource group resource block that includes quantity, the present embodiment is not limited.It is corresponding, be
Each terminal distribution PDMA pattern, which can be, to be randomly assigned, or the PDMA pattern that interference is not present is chosen from PDMA matrix
It is allocated.
Such as a PDMA matrix, it can be incited somebody to action when each PDMA pattern in PDMA matrix is divided into M subset
There is no the PDMA patterns of interference to be divided in a subset in each PDMA pattern, such as by there is no altogether in each PDMA pattern
It is divided in a subset with the PDMA pattern of resource block, thus can preferentially choose and be not present when carrying out the distribution of PDMA pattern
The PDMA pattern of interference.And dividing PDMA pattern can describe by means of non-directed graph, for example, if if being described with non-directed graph, it can
It is right if there is interference between two PDMA patterns each PDMA pattern in a PDMA matrix is regarded as a node
There is an arc between two nodes answered.If a node can reach another node via one or more arc, this two
A node is connection, to be considered as asking the connection in a non-directed graph the division of PDMA pattern each in PDMA matrix
The problem of figure, by two node divisions of connection into different subsets.Include PDMA pattern 1 to PDMA pattern below with one
It is illustrated for 8 PDMA matrix:
The corresponding each terminal of the PDMA matrix has: terminal 1 to terminal 4, is respectively terminal 1 from PDMA matrix to terminal
4 distribution: PDMA pattern 1, PDMA pattern 3, PDMA pattern 5 and PDMA pattern 6 (can be to be randomly assigned or choose to be not present and do
The PDMA pattern distribution disturbed), if terminal 1 to terminal 3 transmits data under i-th of time slot, terminal 1 to terminal 3 successively makes
It is transmitted with PDMA pattern 1,3,5；Under i+1 time slot if terminal 2 to terminal 4 transmit data, terminal 2 to terminal 4 according to
It is secondary to be transmitted using PDMA pattern 3,5,6.
By the example above it is found that if the multiple PDMA patterns of a terminal distribution, then being schemed in adjacent time-slots using PDMA
When sample transmits data, different PDMA patterns can be chosen from the PDMA pattern for its distribution and be transmitted, why chosen
Different PDMA patterns carry out transmission be because are as follows:
For the terminal for using PDMA technology in same resource group, in some cases (when channel with terminal
Prolong with receive power in relation to) can have the overlap problem of constellation point, if continue to using may cause constellation point overlapping PDMA
Pattern can then to interfere with each other between terminal, so improve transmission error probability, and the present embodiment by adjacent time-slots from
Distribution multiple PDMA patterns in choose different PDMA modes, can to avoid between terminal always using there are constellation point overlappings
PDMA pattern, thus reduce because constellation point overlapping caused by terminal interference problem, and then reduce erroneous transmissions probability.
102: under the adjacent time-slots for belonging to the first predetermined period, control uses each terminal pair of the same PDMA pattern
It answers the different resource block of resource group and uses the frequency hopping step-length of each terminal of the same PDMA pattern identical, so that each terminal
In the different time-gap of same first predetermined period, different resource blocks and identical frequency hopping step-length can be used, if same
The frequency hopping step-length of each terminal is different under the different time-gap of a first predetermined period, then two terminals of corresponding different resource block
The case where constellation point overlapping (such as sharing the same resource block) is likely to occur after frequency hopping, and then interference is mutually generated, lead to thus
Crossing each terminal reduces terminal room by the way of identical frequency hopping step-length in the different time-gap of same first predetermined period
Interfere with each other, and then reduce erroneous transmissions probability.
In the present embodiment, control using the same PDMA pattern each terminal corresponding resource group different resource block and
It is using a kind of identical feasible pattern of the frequency hopping step-length of each terminal of the same PDMA pattern:
To the terminal for the PDMA pattern that number is k in m-th of subset for using PDMA matrix, it is based on formulaThe frequency hopping step-length of the terminal is calculated, wherein ns'=Ns·nf+ns, NsIt is each terminal
The number of timeslots that a corresponding frame includes, nfFor the frame number for the frame that terminal transmission data to be transmitted uses, nsFrame is corresponded to for frame number
Timeslot number, KmThe number of PDMA pattern when for each PDMA pattern in PDMA matrix being divided into M subset in each subset,
P be greater thanPrime number, m=1,2 ... ..., M, k=1,2 ... ..., Km, whereinTable
Show integerDivided by integer KmRemainder,Expression is not more thanMaximum integer.And at this
In embodiment, nfAnd nsValue be incremented by since 0.
It is q=1,2 to number in m-th of subset is used ..., KmThe terminal of -2 PDMA pattern is based on formulaIt calculates the terminal and uses the sequence of the resource block of resource group
Number, nRBFor the serial number for the resource block that the corresponding base station of the terminal is the terminal distribution,For the frequency band for transmitting data to be transmitted
Including resource block quantity, and transmit data to be transmitted frequency band be divided into P subband, each subband includes same number
Resource block.
It is q=K to number in m-th of subset is usedm-1,KmPDMA pattern terminal, be based on formulaIt calculates the terminal and uses the serial number of the resource block of resource group.
From above-mentioned formula it is found that if PDMA pattern be it is same, be such as assumed to be k, then according to formulaCalculated frequency hopping step-length k ' is also unique, therefore can to belong to same
The adjacent time-slots of a first predetermined period, then control using the same PDMA pattern but the different resource block of corresponding resource group it is each
The frequency hopping step-length of a terminal is identical.And the first predetermined period is related to number of sub-bands P in the present embodiment, the such as first default week
Phase can beA time slot.
After for each terminal distribution resource block, to each terminal then can: using be the terminal distribution PDMA pattern
Resource block in corresponding resource group transmits the data to be transmitted of the terminal.
From above-mentioned technical proposal it is found that determining the corresponding PDMA matrix of resource group and the use for being used for transmission data
In the case where each terminal of PDMA matrix, in the adjacent time-slots for belonging to the first predetermined period, control is schemed using the same PDMA
The frequency hopping step-length phase of the different resource block of each terminal corresponding resource group of sample and each terminal using the same PDMA pattern
Together, that is to say, that belong to each terminal under the different time-gap of same first predetermined period frequency hopping step-length is identical but resource block not
Together, the probability for causing terminal to share the same resource block after frequency hopping because of frequency hopping step-length difference is reduced, is thus reduced between terminal
Interfere with each other, and then reduce because interference caused by transmission error probability.
Referring to Fig. 2, it illustrates another flow chart of data transfer control method provided in an embodiment of the present invention,
On the basis of Fig. 1 can with the following steps are included:
103: if adjacent time-slots belong to the first different predetermined periods, controlling the frequency hopping step-size change one of each terminal
It is secondary.In the present embodiment, the frequency hopping step-size change of each terminal is controlled if the first different predetermined periods is belonged to if adjacent time-slots
It is once to pass through above-mentioned formulaIt realizes, reason is as follows:
WhenWhen,WhenWhen,…….So every processAfter a time slot (can be considered as the first predetermined period), each terminal is corresponding
Frequency hopping step-length will change, and as seen from the above description change after the corresponding frequency hopping step-length of each terminal same first
Predetermined period is still identical, so that each each terminal of first predetermined period will not share the same resource block.
104: the corresponding terminal of PDMA pattern under i-th of time slot using identical running time-frequency resource with i-th+N number of time slot under
It is identical using the corresponding terminal of PDMA pattern of identical running time-frequency resource, N be the first predetermined period, i=0,1 ... ..., N-1, thus
For the terminal for using same running time-frequency resource to transmit with different PDMA patterns, if it exists the case where constellation point overlapping, then lead to
Crossing control unit can be such that the situation occurs once every by the first predetermined period, to reduce mutual dry between terminal
It disturbs, transmission error probability caused by reducing because of interference.
105: controlling each terminal at interval of the corresponding all subbands of the second predetermined period traversal resource group, wherein second is pre-
If the period quantity of all subbands corresponding to resource group is related, such as the second predetermined period is P time slot.
In the present embodiment, controlling each terminal can at interval of the corresponding all subbands of the second predetermined period traversal resource group
To be based on above-mentioned formula:
WithIt realizes, reason is as follows:
From formulaIn
Part and formulaIn (k ' n 's) mod portion P can see
Out: working as ns'=rP, rP+1 ... rP+P-1, when wherein r is integer,Value is constant, it is possible to think terminal frequency hopping
Step-length is a subband of k ', jumps out behind frequency highest one end of entire frequency band and to come in that (this is leaned on divided by P remainder from the minimum one end of frequency again
Number is to guarantee).According to formulaIt is known that the value range of k ' is from 1 to Km.It can
It is learnt with deriving as n 's=rP, rP+1 ... the n ' calculated when rP+P-1RBCertainly it will not repeat.Because if having duplicate
Words, it is assumed that corresponding time slot difference is Δ n 's, and have (Δ n 'sK ') modP=0.But because Δ n 's< P, k ' < P and P is
Prime number, so (Δ n 's·k′)mod P≠0.So contradiction, therefore it is known that work as ns'=rP, rP+1 ... it is counted when rP+P-1
The n ' calculatedRBCertainly it will not repeat, i.e., primary traversal be completed to P all subbands, for each terminal,
It can take transmission data to be transmitted in all P sons, and terminal is avoided to transmit on the poor frequency point of channel quality always, from
And improve the transmission performance of terminal.
The present embodiment in order to better understand illustrates number provided in this embodiment below by a practical PDMA matrix
According to transfer control method, wherein practical PDMA matrix is as follows:
6 PDMA pattern multiplexings are shared in 4 resource particles, pattern is that column 1 arrive column 6 by place column number.According to money
The shared relationship of source particle, according to the aforementioned method for seeking connected subgraph using non-directed graph, this 6 can be divided into M=2
Subset: { column 1, column 3, column 4 } and { column 2, column 5, column 6 }.Wherein K1=K2=3.To the pattern column 1 that the 1st son is concentrated, column 3, column 4
1,2,3 are renumbered as in subset range.To the pattern column 2 that the 2nd son is concentrated, column 5, column 6 are compiled again in subset range
Number be 1,2,3.Each pattern of subset 1 uses PDMA matrix the 1st, the corresponding resource particle of 2 rows, and each pattern of subset 2 uses
PDMA matrix the 3rd, the corresponding resource particle of 4 rows.Therefore there is no interference between each pattern of subset 1 and each pattern of subset 2.
By taking the frequency hopping of subset 1 as an example.The prime number P=5 greater than 3 is taken, the frequency band for being used for transmission data to be transmitted is divided
For 5 subbands.Assuming thatThen each subband includes 20 PRB (resource block).Assuming that using in PDMA pattern subset
The terminal for the pattern that number is 1 has 5, and number is #1 to #5, is assigned by base station carry out uplink on subband 0 to 4 respectively；
Terminal using the pattern that number is 2 in PDMA pattern subset has 5, and number is #6 to #10, is assigned respectively by base station in subband
Uplink is carried out on 0 to 4；Terminal using the pattern that number is 3 in PDMA pattern subset has 5, and number is #11 to #15,
It is assigned respectively by base station and carries out uplink on subband 0 to 4.
Assuming that having N in a frames=20 time slots.According to available above-mentioned 15 terminals of above-mentioned formula in the 0th frame and
The subband used in 1st each time slot of frame, as shown in Figure 3 and Figure 4, the wherein number in Fig. 3 and Fig. 4 in 3 lattices of a certain row
The number for the terminal that should be transmitted on the subband, as can be seen from figs. 3 and 4, for each terminal, it is every by P=5 when
Gap (can be considered as the second predetermined period), can traverse primary all subbands.To using in PDMA pattern subset 1 totally 3 figures
For all 15 terminals of sample, every processA time slot (can be considered as the first predetermined period), can just occur end
Hold combined repetition.In addition, every processAfter a time slot, the corresponding frequency hopping step-length of each PDMA pattern will change.
From the above it is found that each terminal is enabled to traverse the frequency for being used for transmission data to be transmitted through this embodiment
Each subband of spectrum, and can be realized rotation of the different PDMA patterns for being multiplexed same resource group between different terminals combination,
So as to the frequency point that the interference of terminal room is effectively reduced, and terminal is avoided to use channel quality poor for a long time, uplink is promoted
Capacity.

So that different time-gap of each terminal in same first predetermined period, can be walked using different resource blocks and identical frequency hopping
It is long, if the frequency hopping step-length of each terminal is different under the different time-gap of same first predetermined period, then corresponding different resource
Two terminals of block are likely to occur the case where constellation point overlapping (such as sharing the same resource block) after frequency hopping, and then mutually generate
