Implementation complexity is reduced, the joint method of reseptance for the treatment of effeciency is improved.
Wherein, the main plot and cooperation cell distribution situation for carrying out CoMP are roughly divided into:
1, the cell on same dsp chip belongs to the corresponding cell of antenna of same base station processor；It carries out
The cell of CoMP cooperation upstream data if being distributed in on a piece of dsp chip merges the transmission for not needing to carry out data, can
The upstream data received to be placed in chip common memory, the reading of upstream data can be directly carried out between cooperation cell
Operation.
2, the cell on different dsp chips or on different BPU plates is not belonging to the day that same base station is blown afloat
The corresponding cell of line；Such minizone carries out needing to carry out by SRIO mouthfuls if data interaction.
3, the cell on the difference base station eNB, such minizone need to carry out the interaction of data by X2 interface.
It is divided into again according to user terminal UE (user equipment) situation:
1, the single user joint transmission CoMP-SU-MIMO mode based on COMP: if carrying out uplink in cooperation cell
UE number it is few, the resource of uplink is more sufficient, then the cell of certain cooperative reception UE uplink informations can be to UE
The user that the resource of occupancy is no longer allocated to this cell uses.In this case, it is possible to reduce information is sent to UE uplink and is done
It disturbs.
2, the multi-user joint transmission CoMP-MU-MIMO mode based on COMP: if carrying out uplink in cooperation cell
UE number it is more, the resource of uplink is more nervous, then the cell of certain cooperative reception UE uplink informations can be to UE
The resource of occupancy and the user of this cell cooperate MU-MIMO technology to use.
(1) the received technology of joint that uplink CoMP is realized in the present embodiment is illustrated by taking two antennas, two cell as an example
Scheme carries out flow chart explanation first against with the cooperation cell situation on a piece of DSP, as shown in Figure 8:
UE is transmitted through the uplink time domain data come and first send to FPGA, carries out preliminary OFDM to upstream data by FPGA and accords with
Number demodulation, the i.e. shift frequency of completion 7.5KHZ, removal CP (cyclic prefix) and FFT transform processing, will treated that data pass through
Dsp chip is given in SRIO oral instructions, is stored in public memory, facilitates two cells to read data and carries out subsequent processing.
Wherein, non-COMP and CoMP-SU-MIMO mode:
Assuming that cellA is main plot, cellB is cooperation cell, is used after merging using cellA under CoMP technical situation
Data, just have the characteristic of four antennas, improve the merging gain of data, cellB not in distribution UE, realizes stream on the resource
Journey figure is as shown in Figure 9.
Wherein, CoMP-MU-MIMO mode:
Assuming that cellA is main plot, cellB is cooperation cell, and UEA is the user of cellA, and UEB is the user of cellB,
UEA and UEB occupies identical resource coordination and carries out MU-MIMO transmission, and implementation flow chart is as shown in Figure 10.
When for carrying out CoMP-MU-MIMO with two cells on a piece of DSP, the biography for carrying out upstream data is not needed
Defeated, each cell is handled after can independently reading frequency domain data, judges whether other cell is complete respectively before channel equalization
At channel estimation and covariance inverse matrix calculating and obtain its calculated result, calculated result equally here can also use
Being stored in public memory facilitates other side to read.The application respectively carries out IRC channel equalization using two cells respectively, then
The result for only taking this cell to need carries out the operations such as subsequent demodulation descrambling decoding.Although two cell of the application has carried out IRC letter
Trace equalization is equal to repetitive operation at this, but reduces the operand of this cell to greatest extent elsewhere, improves operation efficiency.
(2) it carries out needing between the cell of CoMP when cooperation cell is located on different dsp chips or BPU plate
Data interaction is carried out, data interaction and operand can also receive when less for cooperation cell, if cooperation cell number
It is more, it needs a large amount of data interaction and calculation amount is huge, implementation complexity is very high.Equally, if cooperation cell is located at
Different base stations then needs to transmit data by X2 interface, realizes that difficulty is bigger.The application proposes one in response to this
Kind reduction procedure, can greatly reduce system implementation complexity.The program is particularly suitable for MU-MIMO, and antenna number is more,
It the case where cooperation cell more equal needs more data interaction, is still carried out by taking two antennas, two cell as an example below for ease of description
Flow chart explanation.
Wherein, non-COMP and CoMP-SU-MIMO mode:
Assuming that cellA is main plot, cellB is cooperation cell, is used after merging using cellA under CoMP technical situation
Data, just have the characteristic of four antennas, improve the merging gain of data, cellB is not on the resource in distribution UE, because needing
Data interaction is reduced processing delay, is merged using the preferable antenna data of signal to reduce data interaction amount, realizes stream
Journey figure is as shown in Figure 11.
The application reduces complexity, Tu12Zhong by using the preferable antenna of signal quality is chosen in this case
It is shown, it may be assumed that be selected by the power or signal-to-noise ratio of two antennas of each cell, if judged using signal-to-noise ratio
If can using previous frame two antennas signal-to-noise ratio, can save in this way this calculate signal-to-noise ratio time improve
Efficiency.Subsequent merging is carried out using the preferable N/2 root antenna of signal is chosen if antenna number is compared with mostly N.Certain this method
It is suitable in the case that antenna number is more or multiple cooperation cells herein, still in the case where operand and time delay allow
The diversity gain that all antenna datas merge acquisition is bigger.The antenna data of cooperation cell cellB is sent, if it is
Cell then needs to transmit by X2 interface then by SRIO mouthfuls of transmission data if it is cell between base station in standing.For Figure 12
Described in antenna data merge, it is only necessary to one for sending over select a antenna data and cellB of cellA
The data of antenna are arranged by format required for subsequent estimation and equilibrium.
Wherein, CoMP-MU-MIMO mode:
Assuming that cellA is main plot, cellB is cooperation cell, and UEA is the user of cellA, and UEB is the user of cellB,
UEA and UEB occupies identical resource coordination and carries out MU-MIMO transmission, and implementation flow chart is as shown in Figure 13.
As it can be seen that proposing a kind of uplink CoMP in the application combines received implementation, to CoMP-SU-MIMO and
How to realize that data aggregate processing improves gain reduction interference and is illustrated respectively under the both of which of CoMP-MU-MIMO:
1) for being in the cooperation cell on a piece of dsp chip using the side that upstream data is stored in public memory
Method reduces the expense of output transmission, improves treatment effeciency.
2) for equally being assisted using by channel estimation results and interference plus noise with the cooperation cell on a piece of dsp chip
The method that variance inverse matrix result is put into public memory reduces data transmission.
3) method that two cooperation cells carry out alone Base-Band Processing respectively is used to CoMP-MU-MIMO mode,
After channel equalization obtains the equilibrium result of two CoMP-UE, after the equilibrium result that each cell chooses oneself cell UE carries out
The mode of in addition pairing UE equilibrium result is given up in continuous operation.
4) a kind of letter is proposed for the situation that cooperation cell antenna number is more or cooperation cell number is more simultaneously
Change method carries out Combined Treatment by choosing the preferable antenna data of signal, the mode for reducing the interaction of half antenna data is come
Reduce link overhead and implementation complexity.
As it can be seen that being had the advantages that in the application
1) for the cooperation cell being located on same dsp chip, the channel estimation that upstream data and channel equalization are used
As a result and interference-plus-noise covariance inverse matrix result is put into public memory, is directly gone accordingly by calculating complement mark judgement
Memory goes the mode for taking result to improve treatment effeciency, reduces data transmission copying；
2) to two cooperation cells under CoMP-MU-MIMO mode, if carrying out the place of two UE in a cell
Reason, needs to know the configuration of two cells, because each cell only has the configuration of this cell UE under normal mode, so not only
Need to modify interface, upper layer scheduling needs to also need to modify by UE memory expanded etc., and after equilibrium another UE it is equal
Weighing apparatus result also needs to pass back, needs to carry out largely to modify and non-CoMP system compatibility is poor, therefore the application is used respective
Cell independently carries out Base-Band Processing, and the mode of the equilibrium result without UE is abandoned after balanced, can be very good carry out system
It is compatible, simplify system and realize, improves treatment effeciency；
3) when there are many cooperation cell number, by increasing day line options, it is preferable that signal is chosen by average signal-to-noise ratio
N/2 root antenna receives the mode of processing carrying out joint and improves treatment effeciency, reduces data transmission, obtains performance and efficiency
Compromise.
