Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a data transmission method, device, electronic device, storage medium and computer program product. Background Art

[0002] With the development of wireless communication technology, most modern wireless communication devices are designed into two main processing units: baseband unit (BBU) and remote radio unit (RRU). The data exchange between the two processing units mainly relies on optical fiber transmission, which has the advantages of flexible deployment, large data transmission bandwidth and lossless transmission. As a data transmission medium, optical fiber has its corresponding transmission protocol according to different application requirements. Common optical fiber communication protocols include Ethernet protocol, Cpri protocol and eCpri protocol. These protocols define the format, rate, error detection and correction, high-speed serial transmission encoding and decoding and data synchronization methods of data transmission in optical fiber communication, ensuring efficient, stable and reliable data transmission.

[0003] Among them, the Ethernet protocol is mainly used in wireless communication systems for data transmission between embedded systems and computers in communication equipment. The processing of Ethernet protocol by embedded systems and computers has the advantages of flexibility and easy development. There are mature technical implementation solutions in product development, which can improve product development efficiency. The entire protocol layer of the Ethernet-based optical fiber transmission protocol includes application layer, transmission layer, network layer, data link layer and physical layer. The development of some protocol layers needs to rely on the software platform, which is suitable for data transmission between systems with software development platforms, server equipment, etc. In the field of communication, the design complexity of hardware-based RF data transmission and baseband processing units is relatively high, which is not conducive to improving product development efficiency. At the same time, due to the complex data parsing and packaging process, the real-time performance of data transmission based on the Ethernet protocol is poor, and it is difficult to meet the data transmission requirements of high-speed frequency hopping.

[0004] Cpri protocol and eCpri protocol are optical fiber transmission protocols used between "baseband processing unit" and "remote radio unit" in wireless communication of the fourth generation mobile communication technology (4G) and the fifth generation mobile communication technology (5G). Cpri protocol and eCpri protocol are data transmission protocol standards formulated by wireless communication equipment manufacturers according to 4G and 5G communication standards. Their data transmission mainly includes user-level data flow, control management layer data flow and synchronization data flow of 4G and 5G communication, and has its specific IQ data, control parameters and transmission rate definitions and transmission methods. IQ data is used to represent the plural form of the signal and is often used for signal processing in wireless communication. The optical fiber transmission protocol based on Cpri protocol and eCpri protocol is a communication protocol developed according to the design requirements of civil 4G and 5G communication systems to realize high-speed data transmission between BBU and RRU devices. It has the advantages of high transmission efficiency and strong specialization. However, due to the differences in communication protocols in terms of IQ data, channel control parameters and high-speed frequency hopping, this transmission protocol is difficult to meet the data efficient transmission of the commonly used ultra-short wave radio communication protocol.

[0005] The above-mentioned fiber optic communication protocols are all designed for corresponding dedicated communication fields. Different communication fields use their corresponding fiber optic communication protocols to enable users to achieve high-speed data communication. However, the Ethernet protocol generally only supports fixed serial rates of 1Gbps (Gigabits per second, gigabits transmitted per second)\10Gbps\50Gbps, and the Cpri protocol and eCpri protocol generally only support the transmission rates required by 4G and 5G communication protocols such as 3.072\6.144\9.830\10.137Gbps. The fiber optic data transmission rates of the two interfaces are relatively fixed. Therefore, for the design of ultra-short wave high-speed frequency hopping technology, it is difficult to achieve efficient and flexible data transmission using existing fiber optic communication protocols.

[0029] Figure 1 is a flow chart of a data transmission method provided in an embodiment of the present application, such as Figure 1 As shown, the data transmission method includes: Step 110, obtaining data to be transmitted and clock parameter control information.

[0031] Step 130: determine the data transmission rate according to the reference clock.

[0032] Step 140: Transmit the data to be transmitted according to the data transmission rate.

[0033] It should be noted that the data transmission method provided in the embodiment of the present application can be applied to the design of ultra-short wave high-speed frequency hopping technology, and the execution subject can be a data transmission device, thereby the following method can be executed by the data transmission device: obtaining the data to be transmitted and the clock parameter control information; Adjusting the accessed master clock based on the clock parameter control information to obtain a reference clock; Determine a data transmission rate according to the reference clock; The data to be transmitted is transmitted according to the data sending rate.

[0034] Figure 2 is a schematic diagram of the architecture of a data transmission device provided in an embodiment of the present application, such as Figure 2 As shown, the data transmission device of the present application can be divided into a master end (Master) and a slave end (Slave), and the master end and the slave end are respectively a baseband processing unit type device and a remote radio frequency unit type device. That is, if the master end is a baseband processing unit type device, the slave end is a remote radio frequency unit type device; if the master end is a remote radio frequency unit type device, the slave end is a baseband processing unit type device.

[0035] The present application can use a Xilinx series Field-Programmable Gate Array (FPGA) to implement the above-mentioned master end and slave end and achieve reliable communication.

[0036] In the present application, both the master end and the slave end may include a clock management module, a transmission control module, a reception control module, a control parameter management module, a transceiver, a controller, and a computer program stored in a memory and executable on the controller. When the controller executes the computer program, the above-mentioned data transmission method is implemented. Among them, the transceiver may be a GT transceiver, which is a device for high-speed data communication that can send and receive data at a rate of gigabits per second. Data can be transmitted (Transmit, TX) and received (Receive, RX) through the GT transceiver.

[0037] In addition, the clock management module is connected to the clock interface, and the master clock can be accessed through the clock interface. Specifically, the clock management module is a clock system that processes the entire optical fiber communication protocol. The clock interface at the master end provides the master clock of the entire system. The master clock provides the reference clock for the GT transceiver after the timing processing of the clock management module. The clock configuration unit in the clock management module mainly processes the clock signal between the GT transceiver and outputs the user data clock according to the configuration parameters set by the configuration parameter management unit for the user to process the received and sent data; the clock management module at the slave end receives the synchronous clock recovered by the GT transceiver unit as the reference clock of the entire system, and outputs the clocks of various functions required by the system after processing by the clock configuration unit to achieve clock synchronization of the optical fiber transmission system.

[0038] The transmission control module mainly processes the transmission logic of data on the transmission channel, while the reception control module mainly processes the reception logic of data on the reception channel. The data may include complex signals (also called IQ data), frequency hopping parameters, channel control parameters and status parameters.

[0039] The control parameter management module mainly provides register parameter reading and writing interface, channel control parameter setting and status information reading interface for the clock management module, transmission control module, reception control module and GT transceiver. The information of channel control parameter setting includes fiber plugging and unplugging status, synchronous link establishment status, clock parameter control information, data transmission rate control information and data reception rate control information.

[0040] Specifically, the user can manage parameters through the control parameter management module according to actual needs, for example, the user can configure clock parameter control information according to needs, so as to realize data transmission at various rates according to the flexibly configured clock parameter control information.

[0041] When either the master end or the slave end acts as the data transmitter, the controller can control the transmission control module to obtain the data to be transmitted including IQ data, frequency hopping parameters, channel control parameters and status parameters, and control the clock management module to extract the clock parameter control information configured therein.

[0042] Furthermore, the controller can control the clock management module to access the master clock through the clock interface, and further control the clock management module to adjust the frequency of the accessed master clock according to the clock parameter control information, and use the master clock after frequency adjustment as the reference clock.

[0043] Furthermore, the controller may control the clock management module to determine the data transmission rate according to the clock information of the reference clock and send the data transmission rate to the transmission control module.

[0044] Furthermore, the controller can control the transmission control module to frame the data to be processed, and send each frame of the framed data to the data transmission interface of the GT transceiver according to the data transmission rate. The GT transceiver can perform high-speed data transmission and reception functions such as parallel-to-serial conversion, serial-to-parallel conversion, 64 / 66B encoding and decoding, high-speed serial channel synchronous handshake link establishment, and then send the processed data to the data receiving interface of the GT transceiver at the receiving end.

[0045] The functions of the GT transceiver in this application can be implemented by using the Internet Protocol (IP) core of the FPGA Transceivers Wizard, which is a tool for generating and configuring high-speed serial transceiver IP cores.

[0046] The GT transceiver at the receiving end receives data through the data receiving interface, deframes each received basic frame, extracts IQ data, frequency hopping parameters, channel control parameters, and status parameters from each basic frame, and sends the data to the relevant interface in real time, thereby completing the transmission of data from the sending end to the receiving end.

[0047] According to the data transmission method of the embodiment of the present application, when data transmission is required, the accessed master clock can be adjusted according to the acquired clock parameter control information to obtain a reference clock; and the data transmission rate required for the data to be transmitted is determined according to the reference clock; and then the data to be transmitted can be transmitted according to the data transmission rate. Since the clock configuration can be flexibly performed to realize data transmission at various rates, the requirements for efficient and flexible data transmission in the design of ultra-short wave high-speed frequency hopping technology can be met.

[0048] This application can meet the design requirements of BBU and RRU interfaces at various rates within the rate range of the design bandwidth that meets the optical fiber module indicators.

[0049] Based on the above embodiment, adjusting the accessed master clock based on the clock parameter control information to obtain the reference clock includes: Parse the clock parameter control information to obtain the target frequency; The frequency of the connected master clock is adjusted according to the target frequency to obtain a reference clock.

[0050] Specifically, the controller of the present application can control the clock management module to parse the acquired clock parameter control information, such as parsing the target frequency, adjustment amount, time interval and other information, and extract the target frequency from it. The target frequency can be the clock frequency or the data transmission rate.

[0051] Then, the controller can control the clock management module to adjust the frequency of the connected master clock according to the target frequency, specifically, adjusting the current frequency of the master clock to the target frequency and using it as a reference clock.

[0052] More specifically, when adjusting the current frequency of the master clock to the target frequency, a phase-locked loop (PLL) circuit may be used to input the target frequency and adjust the frequency of the master clock through feedback.

[0053] If the target frequency is the data transmission rate, the corresponding clock frequency can be determined according to the conversion relationship between the data transmission rate and the clock frequency, and the current frequency of the master clock can be adjusted to the clock frequency and used as the reference clock.

[0054] The present application adjusts the accessed master clock according to the clock parameter control information, which can realize flexible configuration of the clock and further realize data transmission at various rates, thus meeting the requirements of efficient and flexible data transmission in the design of ultra-short wave high-speed frequency hopping technology.

[0055] Based on the above embodiment, determining the data transmission rate according to the reference clock includes: Determine the number of data bits that can be transmitted in each clock cycle of the reference clock; Multiply the number of data bits by the frequency of the reference clock to get the data transmission rate.

[0056] Specifically, the controller may control the clock management module to determine the frequency and period of the reference clock and determine the number of data bits that can be transmitted in each clock period.

[0057] Furthermore, the data transmission rate can be obtained by multiplying the number of data bits that can be transmitted in each clock cycle by the frequency of the reference clock.

[0058] After adjusting the accessed main clock according to the clock parameter control information, the present application realizes flexible configuration of the clock, thereby further determining the data transmission rate, and then realizing data transmission at various rates, thus meeting the needs of efficient and flexible data transmission in the design of ultra-short wave high-speed frequency hopping technology.

[0059] Based on the above embodiment, transmitting the data to be transmitted according to the data transmission rate includes: Performing framing processing on the data to be transmitted to obtain framing data; The framed data is transmitted according to the data transmission rate.

[0060] Further, the data to be transmitted is framed to obtain framed data, including: The data to be transmitted is framed according to the frame structure of the complex signal, frequency hopping parameters, channel control parameters and state parameters to obtain framed data.

[0061] Specifically, after acquiring the data to be transmitted, the controller may control the sending control module to perform framing processing on various types of data in the data to be transmitted according to a preset basic frame structure for transmitting and receiving, and obtain the framed data after completing the framing processing.

[0062] Figure 3 is a schematic diagram of a basic frame structure for sending and receiving data provided in an embodiment of the present application, such as Figure 3 As shown, in the present application, the controller can control the sending control module to group the data to be processed, including IQ data, frequency hopping parameters, channel control parameters, status parameters and other data, into frames according to the frame structure of IQ data, frequency hopping parameters, channel control parameters and status parameters, that is, the data in each frame of data has the structure of IQ data, frequency hopping parameters, channel control parameters and status parameters.

[0063] In one embodiment, if the data to be transmitted can be composed of three frames, the transmitted data is the framing state of IQ data, frequency hopping parameters, channel control parameters, status parameters, IQ data, frequency hopping parameters, channel control parameters, status parameters, IQ data, frequency hopping parameters, channel control parameters, and status parameters.

[0064] Furthermore, the controller can control the sending control module to send each frame of the framed data to the data sending interface of the GT transceiver according to the data sending rate. The GT transceiver can perform high-speed data receiving and transmitting functions such as parallel-to-serial conversion, serial-to-parallel conversion, 64 / 66B encoding and decoding, high-speed serial channel synchronous handshake link establishment, and then send the processed data to the data receiving interface of the GT transceiver at the receiving end.

[0065] Each frame of data in the present application includes IQ data, frequency hopping parameters, channel control parameters, and status parameters, which can realize low-latency transmission of IQ data and control parameters, and through framing, all data are transmitted through basic frames, which can greatly reduce the complexity of data processing and ensure that the data transmission requirements of ultra-short wave high-speed frequency hopping communication are met.

[0066] In one embodiment, after adjusting the accessed master clock based on the clock parameter control information to obtain the reference clock, the method further includes: The reference clock is sent to a receiving end of the data to be transmitted, so that the receiving end determines the data receiving rate based on the reference clock and receives the data according to the data receiving rate.

[0067] Specifically, after the controller of the present application controls the clock management module to adjust the connected master clock based on the clock parameter control information to obtain the reference clock, it can also control the clock management module to send the reference clock to the GT transceiver at the receiving end of the data to be transmitted through the GT transceiver.

[0068] The controller at the receiving end can control its clock management module to use the synchronization clock recovered by the received GT transceiver as the reference clock of the entire system, and output the clocks of various functions required by the system after processing by the clock configuration unit to achieve clock synchronization of the optical fiber transmission system.

[0069] After obtaining the reference clock, the clock management module at the receiving end can determine the frequency and period of the reference clock and the number of data bits that can be transmitted in each clock period.

[0070] Furthermore, the data reception rate can be obtained by multiplying the number of data bits that can be transmitted in each clock cycle by the frequency of the reference clock.

[0071] Furthermore, the controller at the receiving end can control the clock management module and send the data receiving rate to the receiving control module at the receiving end, so that the receiving control module can receive the data sent by the sending end according to the data receiving rate, and further deframe the received data and transmit it to the corresponding interface.

[0072] The present application can realize flexible configuration of the clock by performing clock synchronization, thereby realizing data transmission at various rates, and thus can meet the demand for efficient and flexible data transmission in the design of ultra-short wave high-speed frequency hopping technology.
