Description

Data transmission method, device and computer storage medium

Technical field

This application relates to the field of communication technology, and in particular, to a data transmission method, device, and computer storage medium.

Background technique

Splitting is a cell radio beam signal coverage change technology. The coverage beam is changed from the original radio beam signal coverage direction and shape to another radio beam signal coverage direction and shape. The splitting technology may include a hard splitting technology and a soft splitting technology. Soft splitting technology is a technology that realizes beam coverage direction change and shape change through software. The cells corresponding to the different beams after beam splitting in the software mode are called soft split beam cells, and each cell corresponds to a certain beam shape. Different beam cells with soft splitting involve beam data combining in downlink transmission and beam data splitting in uplink receiving. In the process of data transmission, downstream data sequentially passes through key processes such as baseband processing, switching processing, intermediate frequency processing, and radio frequency processing, and upstream data sequentially passes through key processes such as radio frequency processing, intermediate frequency processing, switching processing, and baseband processing. Beam data combining or beam data splitting.

The baseband processing includes restrictions on other hardware and software specifications, switching processing, medium radio frequency and other processing specifications in the baseband chip, as well as the common public radio interface (Common Public Radio Interface, CPRI) transmission bandwidth limitation between the baseband board and the medium radio frequency, resulting in baseband A single board cannot support more combined road communities. For example, the key processing specifications inside the baseband chip support M antenna processing, that is, the baseband chip supports up to N cells, and this chip constraint prevents the chip from supporting more than N split cells. Another example is that the specification of the routing and switching module between the baseband processing and the mid-frequency processing supports X cells to be combined and split. If the number of split cells exceeds X, the switching module cannot support it. Another example is that CPRI transmission bandwidth limitation can only support the uplink and downlink data transmission of Y cells, and cannot support the establishment of more than Y split cells. It can be seen that how to effectively support more split cells is a technical problem that needs to be solved urgently.

Downlink transmission refers to the process by which the network device transmits data to the terminal device, and downlink data refers to the data transmitted by the network device to the terminal device. Uplink transmission refers to the process in which the terminal device transmits data to the network device, and uplink data refers to the data transmitted by the terminal device to the network device. The split beams involve beam data combining in downlink transmission and beam data splitting in uplink reception.

Taking the schematic diagram of downlink combining and uplink splitting in the downlink and uplink processing flow shown in FIG. 2 as an example, during the processing of downlink data, the downlink data sequentially passes through the baseband processing, switching processing, intermediate frequency processing, and radio frequency processing. Process. During the processing of uplink data, the uplink data passes through key processes such as radio frequency processing, intermediate frequency processing, switching processing, and baseband processing. The entire downstream and upstream processing flow supports CPRI and eCPRI (extended CPRI) interfaces. In the figure, the Point interface or adjacent upstream and downstream function points can be used as combining and/or branching nodes. Alternative nodes for road branching can be used as reference for specific implementation.

Specifically, taking the schematic diagram of downlink combining and uplink splitting shown in FIG. 3 as an example, in the processing of downlink data, the baseband processing may specifically include: the downlink data is sequentially subjected to downlink symbol processing, inverse Fourier transform IFFT/ Fourier transform FFT processing, CPRI framing interface (INTF) processing and CPRI data routing and forwarding processing. In the process of processing the uplink data, the baseband processing may specifically include: the uplink CPRI data is sequentially subjected to forwarding processing, CPRI deframe processing of the INTF interface, FFT processing, and uplink symbol processing. In addition, the cell combining and splitting control module can select the downlink combining point and the uplink splitting point through adaptation or configuration, for example, before IFFT processing, after IFFT processing and before switching module processing, CPRI framing processing of INTF interface, The CPRI data routing and forwarding processing of the switching module, the intermediate frequency module processing, or the radio frequency module processing perform downlink combining, such as after IFFT processing, after the switching module processing, and before the FFT module processing, switching module processing, intermediate frequency module processing, or radio frequency module processing Upstream branch. Among them, FFT module processing can realize Fourier transform FFT/inverse Fourier transform processing (Inverse Fast Fourier Transform, IFFT) and other functional processing, other functional processing such as adding cyclic prefix (Cyclic Prefix, CP), removing CP or DC Suppression processing, etc. The INTF module can implement CPRI protocol negotiation and deframing. The forwarding module can realize the forwarding of CPRI protocol. The intermediate frequency module can implement intermediate frequency processing. The radio frequency module can realize radio frequency processing.

Among them, baseband processing and switching module processing, intermediate frequency module processing, and radio frequency module processing can be deployed in the same chip, the same board, or different chips, different boards, or even different board frames. Here No special constraints.

Wherein, the positions of the downstream merge and the upstream shunt are allowed to be asymmetric, and they can be processed at different node positions in the processing flow, or can be processed at the same node position in the processing flow, which is not specifically limited by the embodiments of the present application. The embodiments of the present application do not limit the number of combined cells and the number of split cells. Among them, due to different hardware implementations, the downlink combining point or the uplink splitting point includes but is not limited to the above positions, and other downlink combining points or uplink splitting points can be selected according to the specific hardware implementation, which is not specifically affected by the embodiments of the present application limits.

In order to better understand the data transmission method, device and computer storage medium disclosed in the embodiments of the present application, the data transmission method implemented in the present application will be described below first. FIG. 4 is a schematic flowchart of a data transmission method disclosed in an embodiment of the present application. The method may be executed by a network device or a chip applied to the network device. The following is an example in which the execution subject is a network device. The method includes but is not limited to the following steps:

Step S401: The network device uses soft splitting technology to split the first data to obtain at least one first unit of data.

The network device may use soft splitting technology to split the first data to obtain at least one first unit of data. The first data may be downlink data.

Step S402: The network device determines the position of the downlink combination.

In one implementation, the network device can determine the location of the downlink combination by configuration. In a specific implementation, the network device may determine the location of the downlink combination according to the configuration information, and the configuration information is used to indicate the location of the downlink combination. Determine the obtained position before the IFFT processing included in the baseband processing, or after the IFFT processing and before the switching module processing, or the switching module processing, or the intermediate frequency module processing, or the radio frequency module processing. Exemplarily, if it is determined that the obtained position is before IFFT processing, the cell data (for example, at least one first unit data) corresponding to each downlink beam is combined in the frequency domain by downlink combining, and then processed in the time domain by IFFT. If it is determined that the obtained position is after IFFT processing and before the exchange module processing, the cell data corresponding to each downlink beam is combined in the time domain by downlink, and then processed by the exchange module and sent to the intermediate radio frequency module. RF module. If it is determined that the obtained position is processed in the switching module, the cell data corresponding to each downlink beam is combined in the switching module to complete the downlink. If the determined position is processed in the intermediate frequency module, the cell data corresponding to each downlink beam is combined in the intermediate frequency module to complete the downlink combination. If it is determined that the obtained position is processed by the radio frequency module, the cell data corresponding to each downlink beam is combined by the radio frequency module.

For example, if the configuration information is used to indicate that the position of downlink combining is before IFFT processing, the network device may determine that the position of downlink combining is before IFFT processing. For another example, if the configuration information is used to indicate that the location of the downlink combination is processed by the radio frequency module, the network device may determine that the location of the downlink combination is processed by the radio frequency module.

In one implementation, the network device can adaptively determine the position of the downlink combination. In a specific implementation, the network device may obtain status information, and determine the position of the downlink junction according to the status information. The status information may include the remaining resource amount of the baseband resources processed by the baseband or the number of split cells that can be supported, and/or the remaining resource amount of the radio frequency resources or the number of split cells that can be supported. The baseband resources include baseband frequency domain resources, Baseband time domain resources and beam domain resources.

For example, the network device can flexibly select the downlink combining point according to the usage of baseband resources or radio frequency resources. When a resource is insufficient, you can choose different junctions to avoid the shortage of resources. For example, when a baseband chip needs to cooperate with another baseband chip for processing, and it is not enough to select a certain chip for downlink combining resources, the forwarding module and the middle radio frequency point can be selected for downlink combining outside the baseband chip. The other modules selected for cooperation may be on the same board, or span other boards or other modules on the board frame.

For another example, the network device can flexibly select the downlink combining point according to the specifications of baseband resources or radio frequency resources. Under the condition of a certain resource limit, you can choose different junctions to circumvent the resource limit. For example, when the frequency domain or time domain processing of a baseband chip has insufficient specifications for the number of split cells supported by its own resources, it needs to be coordinated with another baseband chip, and it is not enough to select a chip itself for downlink combining resources. The forwarding module and the middle radio frequency point can be selected for downlink combining outside the baseband chip. The other modules selected for cooperation may be on the same board, or span other boards or other modules on the board frame.

FIG. 5 is a schematic flowchart of another data transmission method disclosed in an embodiment of the present application. The execution subject of the method may be a network device or a chip applied to a network device. The following is an example in which the execution subject is a network device. The method includes but is not limited to the following steps:

Step S501: The network device decompresses the third data and transmits the decompressed third data.

The network device may perform CPRI decompression and transmission on the third data.

Step S502: The network device determines the location of the upstream branch.

In one implementation, the network device can determine the location of the upstream shunt through configuration. In a specific implementation, the network device may receive configuration information from the network device. The configuration information is used to indicate the location of the uplink branch, and the location of the uplink branch is determined according to the configuration information. The determined position is after the FFT processing included in the baseband processing, or after the switching module processing and before the FFT processing, or the switching module processing, or the intermediate frequency module processing, or the radio frequency module processing. Exemplarily, if it is determined that the obtained position is after the FFT processing, after completing the conversion from the time domain to the frequency domain (usually through FFT processing), the antenna frequency domain data branching can be directly performed to split the antenna frequency domain data to The cell (beam cell) corresponding to each beam is processed by each beam cell for uplink demodulation, decoding, channel estimation, etc.; or after the uplink has completed the time domain to frequency domain conversion, the antenna domain is converted to the beam domain, and then the beam domain Then, different beams are branched out, and the data in the beam domain is distributed to each beam cell, and each beam cell performs processing such as uplink demodulation, decoding, and channel estimation. If it is determined that the obtained position is processed by the switching module and before the FFT processing, the received data from the switching module is branched out to process data corresponding to the time domain of cells corresponding to different beams, and each beam cell performs subsequent processing according to the time domain. If it is determined that the obtained position is processed by the switching module, and the switching module supports splitting, the switching module completes the reception data (such as CPRI data output by the intermediate frequency module) from the previous module to split the corresponding processing data of different split beams , Each beam cell performs subsequent processing according to the time domain. If the determined position is processed in the intermediate frequency module, the intermediate frequency module completes the reception of data from the previous module (such as the data output by the radio frequency module) to branch out the corresponding processing data of different split beams, and each beam cell performs follow-up according to the intermediate frequency domain deal with. If it is determined that the obtained position is processed by the radio frequency module, the radio frequency module completes the reception data (such as the data output by the antenna module) from the previous module to branch out the corresponding processing data of different split beams, and each beam cell performs follow-up according to the radio frequency domain deal with.

For example, if the configuration information sent by the branch control module is used to indicate that the position of the upstream branch is after FFT processing, the network device may determine that the position of the upstream branch is after FFT processing. For another example, if the configuration information is used to indicate that the location of the uplink branch is processed by the radio frequency module, the network device may determine that the location of the uplink branch is processed by the radio frequency module.

In one implementation, the network device can adaptively determine the location of the upstream shunt. In a specific implementation, the network device may obtain status information, and determine the location of the uplink branch according to the status information. Wherein, the status information includes the remaining resource amount of the baseband resource processed by the baseband or the number of split cells that can be supported, and/or the remaining resource amount of the radio frequency resource or the number of split cells that can be supported, and the baseband resource includes the Baseband frequency domain resources, the baseband time domain resources and beam domain resources.

For example, the network device can flexibly select the upstream branch point based on the usage of baseband resources or radio frequency resources. When a resource is insufficient, you can choose different branch points to avoid the shortage of resources. For example, when a baseband chip needs to be coordinated with another baseband chip for processing, and it is not enough to select a certain chip for uplink splitting resources, you can choose to perform uplink splitting at the forwarding module and mid-frequency point outside the baseband chip. The other modules selected for cooperation may be on the same board, or span other boards or other modules on the board frame.

For another example, the network device can flexibly select the upstream branch point according to the specifications of baseband resources or radio frequency resources. Under the condition of a certain resource limit, you can choose different branch points to circumvent the resource limit. For example, when the frequency domain or time domain processing of a baseband chip does not have enough specifications for the number of split cells supported by its own resources, and it needs to be coordinated with another baseband chip, and it is not enough to choose a certain chip for uplink splitting resources, The forwarding module and the middle radio frequency point can be selected for upstream branching outside the baseband chip. The other modules selected for cooperation may be on the same board, or span other boards or other modules on the board frame.

In an implementation manner, when the remaining resource amount of the baseband frequency domain resource processed by the baseband is greater than a first resource threshold, it is determined that the position of the uplink shunt is after FFT processing. When the remaining resource amount of the baseband frequency domain resource processed by the baseband is less than or equal to the first resource threshold, and the remaining resource amount of the baseband time domain resource processed by the baseband is greater than a second resource threshold, the uplink shunt is determined Is after the switching module processing and before the FFT processing. When the remaining resource amount of the baseband resource processed by the baseband is less than or equal to a third resource threshold, and the remaining resource amount of the switching module is greater than a fourth resource threshold, it is determined that the uplink shunt is processed by the switching module. When the remaining resource amount of the baseband resource processed by the baseband is less than or equal to the third resource threshold, the remaining resource amount of the switching module is less than or equal to the fourth resource threshold, and the remaining resource amount of the intermediate frequency module is greater than fifth When the resource threshold is reached, it is determined that the uplink branch is processed by the intermediate frequency module. When the remaining resource amount of the baseband resource processed by the baseband is less than or equal to the third resource threshold, the remaining resource amount of the switching module is less than or equal to the fourth resource threshold, and the remaining resource amount of the intermediate frequency module is less than or equal to the When the fifth resource threshold is greater, and the remaining resource amount of the radio frequency module is greater than the sixth resource threshold, it is determined that the uplink branch is processed by the radio frequency module.

In an implementation manner, when the number of split cells that can be supported by the baseband frequency domain resource processed by the baseband is greater than a first number threshold, it is determined that the position of the uplink shunt is after FFT processing. When the number of split cells supported by the baseband frequency domain resource processed by the baseband is less than or equal to the first number threshold, and the number of split cells supported by the baseband time domain resource processed by the baseband is greater than the second number threshold, It is determined that the position of the upstream branch is after the processing by the switching module and before the FFT processing. When the number of split cells supported by the baseband resource processed by the baseband is less than or equal to a third number threshold, and the number of split cells supported by the switching module is greater than a fourth number threshold, it is determined that the uplink split Switch module processing. When the number of split cells that the baseband processed resource can support is less than or equal to the third number threshold, the number of split cells that the switching module can support is less than or equal to the fourth number threshold, and the intermediate frequency module can support When the number of split cells is greater than the fifth number threshold, it is determined that the uplink branch is processed by the intermediate frequency module. When the number of split cells that the baseband processing resources can support is less than or equal to the third number threshold, the number of split cells that the switching module can support is less than or equal to the fourth number threshold, and the intermediate frequency module can support When the number of split cells is less than or equal to the fifth number threshold, and the number of split cells that the radio frequency module can support is greater than the sixth number threshold, it is determined that the uplink split is processed by the radio frequency module.

In the embodiment of the present application, the complexity is reduced by domain conversion. The uplink splitting allows frequency domain, time domain, antenna domain, beam domain, etc. to be transformed, instead of directly splitting in the frequency domain and time domain, but After the beam domain transformation, the branch processing is performed, and a reasonable processing method is selected to reduce the complexity. For example, uplink processing is switched from the antenna domain to the beam domain to reduce complexity.

Step S503: The network device performs uplink splitting of the decompressed third data at the determined location to obtain at least one third unit data.

In the method described in FIG. 5, the network device decompresses the split beam data during uplink transmission and then splits it to avoid the baseband splitting and destroying the FCA header and check factor after decompression. Support CPRI's high compression ratio algorithm (for frame header and other compressed high compression ratio algorithms, you need to decompress and then branch, for the frame header uncompressed algorithm, the decompression and branching are not necessarily processed sequentially), so that in the baseband It can effectively support more split cells under the conditions of processing, including hardware and software specifications in the baseband chip, exchange processing, medium radio frequency and other processing specifications, and CPRI transmission bandwidth limitations between the baseband board and the medium radio frequency.

Taking the supported cell as a Massive MIMO cell as an example, through the data transmission method disclosed in the embodiments of the present application, under the scenario that the CPRI transmission bandwidth is unchanged, the supported MM cell specification is doubled.

For example, the single board supports 2*20M 64T64R to support 4*20M 64T64R after splitting. The 64T64R 20MHz Massive MIMO cell requires a CPRI transmission bandwidth of about 9.8G*8=80G. In the scenario where the CPRI is compressed to 2:1, 100G CPRI fiber can support two 64T64R 20MHz cells. By flexibly selecting the combining and splitting points, 100G CPRI fiber can support more than two 64T64R cells. For example, if one 64T64R 20M cell splits two 64T64R 20M cells, the transmission resources can support a total of four 64T64 20MHz split cells, if If one splits three split cells, the transmission resources can support a total of six 64T64 20MHz split cells.
