Detailed Description

In the related art, MIMO multi-antenna technology is one of the basic components of the physical layer of the LTE (Long Term Evolution ) system, and can be mainly divided into three modes, spatial multiplexing, transmission diversity and beamforming. The 3D-MIMO technology adopts a large-scale array antenna, is based on a beam forming algorithm, and combines an SDMA (Space Division Multiple Access, space division multiplexing access) technology to realize multi-scene coverage.

At present, the transmission scheme of the 3D MIMO single optical fiber DPLP (Down Physical Layer Processor, downlink physical layer processor) includes two main technical schemes of S3 (sectored 3, one sector is configured with three carrier frequencies) and S111 (sectored 1, three sectors are configured with three carrier frequencies), and the implementation process is as follows:

1. s3 mode

First, referring to fig. 1A, which is a hardware configuration diagram in an S3 mode in the related art, from fig. 1A, it may be determined that cell data of three cells is transferred through one optical fiber, and baseband transmission is performed through one BBU. The cell data is a basic frame obtained after the grouping by the CPRI protocol.

Referring to fig. 1B, under the CPRI protocol, a basic frame transmitted through an active antenna processing unit AAU1 is received, where the basic frame includes frequency domain data (assumed to be cell 0, cell 1, and cell 2) for transmitting three cells. When baseband transmission is carried out on the BBU, the main realization function is to split the cell data of each cell in a basic frame; and then decompressing the compressed PUCCH (Physical Uplink Control Channel )/PUSCH (Physical Uplink Shared Channel, physical uplink shared channel) frequency domain data in the cell data, carrying out channel combination with SRS (Sounding Reference Symbol ) data, and transmitting the cell data after channel combination to a next-stage processor for processing through an Aurora interface protocol.

The functions implemented by the modules in fig. 1B are explained below:

(1) Optical port receiving module optical_inf: for identifying valid data in the cell data in the basic frame.

(2) Cell data buffer module ul3d_buf: and the method is responsible for caching effective data in the cell data and regularly reading the effective data.

(3) Cell data splitting module dis_cell: the method is used for splitting the plurality of cell data contained in one basic frame and realizing the alignment operation of the cell data, namely ensuring that the clock time of the split plurality of cell data reaching the next processing module is the same.

(4) Cell data processing module cell_process: and the method is responsible for respectively separating the PUCCH/PUSCH frequency domain data and the SRS channel data in the cell data, decompressing the PUCCH/PUSCH frequency domain data and then merging the channels, wherein the function of each sub-module in the function of the module is realized as follows:

(4-1) decompression Module Decmper: for decompressing PUCCH/PUSCH frequency domain data;

(4-2) frequency domain data buffer module cycbuf: the method is responsible for caching decompressed PUCCH/PUSCH frequency domain data;

(4-3) a sounding reference symbol buffer module srs_uram: representing transmission of SRS channel data;

(4-4) channel merge module mux: the method is used for realizing channel combination of the decompressed PUCCH/PUSCH frequency domain data and SRS channel data.

(5) Aurora: and the transmission interface module is responsible for transmitting the data processed by the cell_process module to the next-stage processor.

Referring to fig. 1C, an arrangement diagram of a CPRI basic frame in an S3 mode in the related art is shown, where a CPRI basic frame format includes 96 double words, and one optical fiber transfers frequency domain data of three cells in the S3 mode, which includes:

(1) 1 st doubleword: CM (control management).

(2) 2 nd doubleword: VPCIE (virtual peripheral component interconnect express, high speed serial computer expansion bus standard).

(3) 3 rd doubleword: the packet header 1 is used for storing packet header information of the PUSCH/PUCCH, the packet header 2 is used for storing packet header information of SRS channel data, and the lower 4 bits are packet effective marks.

(4) Double words 4-33, 34-63, 64-93: for storing data information of cell 0, cell 1 and cell 2, respectively.

(5) 94 th to 96 th doubleword: a small number of empty doublewords, i.e. no padding data.

In this mode, since one optical fiber needs to transmit cell data of three cells, but the format of the basic frame is fixed, the space allocated for transmitting cell data for each cell in one basic frame is limited, resulting in a limited coverage range of the antenna.

2. S111 mode

In order to increase the coverage of the antenna with respect to the S3 mode, referring to fig. 2A, which is a hardware structure diagram in the S111 mode in the related art, from fig. 2A, it may be determined that one optical fiber transmits cell data of one cell, and baseband transmission is performed on three basic frame data of three cells transmitted by three optical fibers through one BBU.

Referring to fig. 2B, an uplink overall frame diagram of transmission on a BBU, under the CPRI protocol, one basic frame transmits frequency domain data of one cell; the functions implemented by each module in the transfer process are the same as those in the S3 mode, and will not be described in detail here. However, in this mode, since each cell exists in one basic frame data, the BBU processes the basic frame of each cell when performing baseband transmission.

Referring to fig. 2C, a schematic layout diagram of a CPRI basic frame in S111 mode according to an embodiment of the present application is provided, where the layout format of the basic frame is the same as that in S3 mode, and the detailed layout format is not described herein.

In this mode, since one optical fiber only transmits the cell data of one cell, that is, the data of the cell 0 in fig. 2C is included between 4 to 93 double words in the basic frame, the cell data of one cell does not actually occupy the entire space allocated for the cell data in one basic frame, so that a great deal of waste of optical fiber resources is caused and the cost is high in this mode.

In view of this, the configuration format of the basic frame obtained by performing the packet by the CPRI protocol adopted in the present application is as shown in fig. 3, that is, the cell data of two cells is transmitted in one optical fiber. Wherein, each AAU transmits a basic frame, and the basic frame transmitted by the AAU comprises packet data based on CPRI protocol of two cells covered by the basic frame.

The cell data of a plurality of cells are transmitted through one optical fiber, so that the transmission resource of one optical fiber can be fully utilized to the greatest extent, the coverage area of each cell is increased compared with that of the transmission through the S3 mode, and the cost is low compared with that of the optical fiber through the S111 mode.

In this basic frame arrangement, typically one BBU can transmit cell data for three cells.

In one case, if an optical fiber is used to transmit the arrangement format of the cell data of two cells, when the cell data of six cells are transmitted through three AAUs, two BBUs can be used for transmission; however, in this case, it may happen that one BBU transmits the cell data of two AAUs, i.e. four cells, and the other BBU transmits the cell data of one AAU, i.e. two cells.

If the two BBUs transmit the cell data of six cells, it can be clearly understood that each BBU transmits the cell data of three cells as the transmission scheme of the most suitable cell data.

Therefore, in this embodiment, the method for processing cell data is used to solve the problem of imbalance of transmission of multiple cell data transmitted by multiple baseband boards, for example, when two baseband boards transmit six or more cell data, the method is used to realize that each BBU transmits cell data of three cells respectively by scheduling the cell data, so that the cell data is transmitted with maximum efficiency.

The following example is only illustrated with one basic frame including 2 cells, and is not intended to limit the number of cells included in one basic frame in the present application. In order to make the objects, technical solutions and advantages of the embodiments of the present application more clear, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application.

The terms "first," "second," "third," and "fourth" and the like in the description and in the claims and drawings are used for distinguishing between different objects and not necessarily for describing a particular sequential or chronological order. Furthermore, the terms "comprise" and "have," as well as any variations thereof, are intended to cover a non-exclusive inclusion. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those listed steps or elements but may include other steps or elements not listed or inherent to such process, method, article, or apparatus.

Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the application. The appearances of such phrases in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. Those of skill in the art will explicitly and implicitly appreciate that the embodiments described herein may be combined with other embodiments.

Referring to fig. 4, a flow chart of a processing method of cell data provided by an embodiment of the present application is applied to a network side device, where the network side device includes a first baseband board and a second baseband board, the number of AAUs connected to the first baseband board is greater than the number of AAUs connected to the second baseband board, and the method is applied to the first baseband board, and includes:

step 401: and receiving a basic frame transmitted by the AAU connected with the first baseband board, wherein the basic frame comprises packet data, and the packet data comprises cell data of a plurality of cells.

Step 402: and scheduling the cell data of at least one cell in the plurality of cells in the basic frame to the second baseband board for baseband transmission processing.

For example, if the first baseband board is connected to the transmission data of two AAU four cells, it is used as a master modulation board, and the second baseband board is connected to the transmission data of one AAU two cells, it is used as a modulated board.

Referring to fig. 5, a schematic structural diagram of a method for processing cell data according to an embodiment of the present application is provided; where "rx" denotes receiving a basic frame containing two cell data transmitted through the AAU, and "tx" denotes transmitting the cell data after baseband transmission processing. The main dispatching board processes the cell data of four cells at the moment, so that the cell data of one cell of the main dispatching board is dispatched to the dispatched board for processing in order to avoid resource congestion caused by the processing of a large amount of data by the main dispatching board.

In an implementation process, the cell data of at least one cell of the plurality of cells in the basic frame is scheduled to the second baseband board, and three possible implementation manners are as follows:

mode one: splitting the packet data in the basic frame to obtain the cell data of each cell; and dispatching the cell data of at least one cell in the split cells to the second baseband board.

In one embodiment, referring to fig. 6, a transmission frame diagram on a first baseband board of a method for processing cell data according to an embodiment of the present application is provided, where it is assumed that the first baseband board receives cell data transmitted by AAU1 and AAU2, and schedules data of cell 0 in AAU1 to a second baseband board for baseband transmission processing.

When in implementation, after splitting cell data of two cells in a basic frame transmitted by a received AAU1 through cell data splitting, namely 'dis_cell', and before decompressing each cell data through cell data processing, namely 'cell_process', data of a cell 0 as shown in fig. 6 is firstly packed through an Aurora interface protocol to obtain Aurora interface protocol packet data of the cell 0 for scheduling; and then transmitted to a second baseband board through an Aurora interface for baseband transmission processing.

It should be noted that "AAU1", "AAU2", and the like are data or units having the same function or function, and the serial numbers are merely for convenience of distinction, and are not used as functionally different limitations.

When the method is implemented, the output address of the cell data of the at least one cell is determined through a preset address line; the output address is used for pointing to the RAM in the Aurora interface module; then, reading the cell data of the at least one cell from the RAM according to the Aurora interface protocol, and carrying out grouping to obtain Aurora interface protocol grouping data; and finally, outputting the Aurora interface protocol group packet data in the at least one cell to the second baseband board for baseband transmission processing. By adding the preset address line, the output scheduling mode of the scheduled cell can be realized.

In the above embodiment, after obtaining packet data of a cell for scheduling, the first baseband board outputs Aurora interface protocol packet data of each cell in the at least one cell to the second baseband board according to the determined output address to perform baseband transmission processing. As shown in fig. 6, "dis_cell_addr" is an address line addr added on the basis of "dis_cell", through which cell data of cell0 can be output to the second baseband board through the Aurora0 interface.

In addition, the transmission frame of the AAU2 in fig. 6 is a processing flow of the baseband transmission processing after the first baseband board receives a basic frame including two cell data transmitted by the AAU, where the detailed description of the functions implemented by each part and the processing flow are the same as those in fig. 1B, so that the details are not repeated herein.

It should be noted that, the configuration format of the packet by Aurora interface protocol is as shown in fig. 7, and mainly includes:

(1) Header information HEAD: take up 2 clock cycles CLK;

(2) Subframe, symbol, antenna information INFO (information): 1 CLK;

(3) Byte length BLEN (Byte Length): 1 CLK;

(4) The cell DATA is the cell DATA to be transmitted;

(5) Tail information TALL: accounting for 2 CLK's.

The implementation provided by this example has the following advantages:

(1) Since the scheduling cell data is located before decompression, the amount of scheduled data is small;

(2) At this time, the cell data of two cells in the basic frame transmitted by the AAU are already split, so that one split cell is dispatched to a second baseband board, and the cell is not required to be distinguished again on the second baseband board;

(3) The implementation does not need to additionally add module processing, so that the cost is not increased or the original transmission module is not changed;

(4) The main decompression processing of the cell 0 is scheduled to the second baseband board, so that the occupied processing resources on the first baseband board, namely the main tone board, are less, and the problem of the main tone board caused by overlarge processed data volume is avoided;

(5) According to the implementation mode, the AAU adopts a multi-antenna technology, and compared with the technical mode that three cells adopt one antenna for transmission in an S3 mode in the related technology, the coverage range of signals is enlarged;

(6) In the embodiment, one antenna transmits the cell data of two cells, and compared with the technical mode of transmitting the cell data by one antenna in the related technology, the use cost of the antenna is reduced.

Mode two: and dispatching the analyzed specified basic frame to the second baseband board for processing, so that the second baseband board processes the cell data of the specified cell in the packet data in the specified basic frame.

In implementation, the designated cell may be selected as a part of the cells in the designated basic frame, for example, in the following manner one, if the master tone transmits two AAUs, the called tone transmits 1 AAU, and each AAU transmits two cells, the method described above, one cell in one AAU of the master tone is transmitted to the called tone, and it is assumed that cell 0.

In addition, if the cell 0 of the two cells in the AAU1 in fig. 8 is scheduled to the to-be-scheduled plate, the master scheduling plate needs to perform baseband transmission processing on the cell data of the cell other than the specified cell in the specified basic frame, that is, the cell 1 in the figure.

Referring to fig. 8, a transmission frame diagram of a second mode is adopted for the first baseband board provided in the embodiment of the present application, for example, in the diagram, after AAU1 passes through an optical port receiving module, i.e. "optical_inf", cell 0 scheduling is performed. It should be noted that, in the implementation, the cell data of two cells in the basic frame transmitted by the AAU1 including the cell 0 is not detached, so after the data of the cell 0 is scheduled to the second baseband board, the basic frame of the AAU1 is optionally copied on the first baseband board, and the first baseband board is agreed to process the data of the cell 1 therein, then after the cell is detached by the "dis_cell", the first baseband board discards the data of the cell 0 according to the agreement, and only performs baseband transmission processing on the cell 1.

In addition, the embodiment of the processing for the AAU2 in fig. 8, in which the first baseband board normally performs the AAU processing for the received AAU, is the same as the embodiment in fig. 6, and will not be described herein again.

In this second embodiment, the scheduling of the cell data of at least one cell of the first baseband board to the second baseband board is also achieved, and in this embodiment, the scheduling of the cell data is located before the decompression of the cell data, so the amount of the scheduled cell data is small, and since the output of the "optical_inf" module is about 20us, the scheduling cell data is rebuffered on the second baseband board for about 30us, and since the consumed time is short, the alignment of the cell data of the other two cells on the second baseband board is easier.

In addition, the embodiment of the present application for outputting the scheduled cell to the second baseband board is the same as the first embodiment, that is, the embodiment is implemented through the preset address line and Aurora interface, so that the description thereof is omitted herein.

Mode three: decompressing the frequency domain data of each cell to obtain decompressed data; channel combination is carried out on the decompressed data of the same cell and the SRS channel data to obtain channel combined data; and scheduling the data combined by the channels of at least one cell in each cell to the second baseband board for baseband transmission processing.

Referring to fig. 9, a flow chart of processing split cell data according to an embodiment of the present application includes:

step 901: and receiving the split cell data.

The cell data of each cell comprises frequency domain data and sounding reference symbol SRS channel data, and the cell frequency domain data comprises PUSCH/PUCCH frequency domain data.

Step 902A: and buffering SRS channel data.

Step 902B: and decompressing the PUCCH/PUSCH frequency domain data.

Step 903: and merging the channels to obtain the data after the channel merging.

Step 904: and outputting the data after channel combination to a next processing module.

Referring to fig. 10, which is a diagram of a third implementation manner of the first baseband board provided in the embodiment of the present application, it can be seen from fig. 10 that data of the cell 0 is scheduled to the second baseband board through the Aurora0 interface.

The scheduling of the cell data in the first baseband board can also be realized through the embodiment, the scheduling is performed after the cell data are decompressed and the data after channel combination are obtained, and the modification on the Aurora0 interface is small.

The above embodiment is described as an embodiment in which the first baseband board is executed as the main tuning board, and the following will continue to describe an embodiment in which the second baseband board is executed as the tuned board.

Referring to fig. 11, a flow chart of a method for processing cell data according to an embodiment of the present application is provided, where the method is applied to a second baseband board, and includes:
