Technical Field

[0003] The present application relates to the field of communication network technology, and in particular to a data transmission method, device and electronic device for a digital optical fiber repeater. Background Art

[0004] A digital fiber optic repeater (DAS) is a relay transponder between a base station (BS) and a mobile station (MS). It is a radio transmission relay device that enhances the signal during wireless communication transmission. It is mainly composed of a near-end unit, optical fiber, and a remote unit. When the digital fiber optic repeater is working, it converts electrical signals into optical signals and transmits them between the near-end unit and the remote unit via optical fiber. Optical fiber transmission between the near-end unit and the remote unit usually adopts the Common Public Radio Interface (CPRI) protocol. In order to obtain a larger transmission bandwidth and transmit a larger amount of data, the baseband data is usually compressed. Related CPRI-based transmission methods mostly compress all baseband data to the same bit width according to a fixed compression ratio. When the compression ratio is lower, that is, the bit width of the compressed data is larger, the distortion caused by data compression is smaller, the compression noise caused is also smaller, and the transmission performance is better. However, at the same time, the amount of data required to be transmitted increases, the transmission bandwidth is smaller, and therefore the system capacity is reduced. Conversely, when the compression ratio is higher, that is, the bit width of the compressed data is smaller, the transmission bandwidth and system capacity are larger, but the transmission noise is also greater, and the transmission performance is poor. It can be seen that in different application scenarios, it is difficult to achieve a balance between system capacity and transmission performance.

[0005] There is currently no effective solution to the problem in related technologies that cannot balance system capacity and transmission performance.

The terms "first," "second," "third," etc. used in this application are only used to distinguish similar objects and do not represent a specific ordering of the objects.

[0048] The method embodiments provided in this embodiment can be applied to a digital fiber optic repeater device. Figure 1 is a structural diagram of the digital fiber optic repeater device in this embodiment. As shown in Figure 1 , the device may include a near-end unit 102, a far-end unit 104, and optical fibers represented by bidirectional arrows. Fiber optic transmission generally utilizes the Common Public Radio Interface (CPRI) protocol. The near-end unit 102 may include, but is not limited to, an antenna interface, a duplexer, a downconverter, an analog-to-digital converter (ADC), an upconverter, a digital-to-analog converter (DAC), a baseband signal processor, and an optical transceiver. The far-end unit 104 has the same components as the near-end unit 102. Those skilled in the art will appreciate that the structure shown in Figure 1 is merely illustrative and does not limit the structure of the digital fiber optic repeater device described above. For example, the device may include more or fewer components than shown in Figure 1 , or have a different configuration than that shown. In one embodiment, the near-end and far-end units also include power amplifiers.

[0049] The digital fiber optic repeater equipment described above acts as a signal intermediary, transmitting signals from the near-end to the far-end. Near-end unit 102 receives downlink signals, converts them from electrical signals to optical signals suitable for fiber optic transmission, and transmits the optical signals to far-end unit 104. Optical fibers transmit the optical signals from near-end unit 102 to far-end unit 104. Far-end unit 104 receives the optical signals from near-end unit 102, converts them into electrical signals, or uplink signals, and transmits them. Specifically, the near-end device 102 receives a downlink signal via an antenna interface, down-converts the downlink signal through a downconverter to an intermediate frequency signal, samples the intermediate frequency signal in an analog-to-digital converter, converts it into a digital signal, processes the digital signal through a baseband signal processor, converts it into an optical signal, and transmits it to the far-end device via optical fiber. The optical transceiver in the far-end device 104 receives the optical signal, converts it into a digital signal after baseband processing, and converts the digital signal into an analog signal through a digital-to-analog converter. The analog signal is then up-converted to an uplink signal and transmitted through the antenna interface. Furthermore, the aforementioned digital fiber optic repeater equipment can also be used to transmit signals from the far-end to the near-end. The duplexers in the near-end device 102 and the far-end device 104 isolate the transmitted and received signals, ensuring that signal reception and transmission can occur simultaneously.

[0050] In this embodiment, a data transmission method for a digital fiber optic repeater is provided. The transmission method of this embodiment is executed by a baseband signal processor, an optical transceiver, and an optical fiber in the digital fiber optic repeater device shown in FIG1 . The baseband signal processor and the optical transceiver may be in the near-end machine 102 or in the far-end machine 104 depending on the signal transmission direction in different scenarios, and no specific limitation is made here.

[0051] FIG2 is a flow chart of a data transmission method for a digital optical fiber repeater according to an embodiment of the present invention. As shown in FIG2 , the flow chart includes the following steps:

[0052] Step S201: assemble target data to be transmitted into multiple target compression units.

[0053] Specifically, the target data primarily consists of baseband signal modulation data (I / Q data). When a digital fiber optic repeater transmits signals between near-end and far-end devices over optical fiber, it does so in basic frames. The line rate of optical fiber transmission is fixed, and under a given system clock, the maximum amount of data that can be transmitted per basic frame is also fixed. For a basic frame, aside from the control information transmitted in the frame header, the remaining space is generally used to transmit compressed baseband signal modulation data. The target data is organized into multiple target compression units, each containing a fixed amount of data, representing the amount of data processed during a single compression operation. This amount can be set based on the specific application scenario and transmission requirements.

[0054] Step S202 : dividing the plurality of target compression units into target compression groups of different categories according to their respective different preset compression ratios; wherein a target compression group includes at least one target compression unit.

[0055] Specifically, the compression ratio in this embodiment refers to the degree of data compression, which can be represented by the ratio of the data size before compression to the data size after compression. Different data types are suitable for different compression ratios. For data with high requirements for data accuracy and signal-to-noise ratio and small bandwidth, a lower compression ratio is configured to prioritize performance. For data with large bandwidth and relatively low accuracy requirements, a higher compression ratio is configured to prioritize system capacity.

[0056] The plurality of target compression units are divided into target compression groups of different categories based on different preset compression ratios of the plurality of target compression units; wherein a target compression group includes at least one target compression unit. Each target compression unit in the same target compression group has the same compression ratio, while target compression units in different target compression groups have different compression ratios.

[0057] Step S203 : compressing each target compression group into a corresponding target transmission group according to the number of target compression units in each target compression group and the compression ratio corresponding to the target compression group.

[0058] Specifically, the target compression units are compressed according to groups. For the target compression units in the same target transmission group, a uniform compression ratio is set, and they are compressed in sequence to obtain target transmission groups with different bit widths. For example, if target compression group A includes x target compression units and the corresponding compression ratio is y, then the compression ratio is set to y, and x compression operations are performed on target compression group A to obtain the corresponding target transmission group A, and the bit width of target transmission group A is z; if target compression group B includes u target compression units and the corresponding compression ratio is v, then the compression ratio is set to v, and z compression operations are performed on target compression group A to obtain the corresponding target transmission group B, and the bit width of target transmission group B is w.

[0059] Step S204: construct a target basic frame based on the target transmission group; wherein one target basic frame includes at least one target transmission group.

[0060] Specifically, optical fibers transmit data in frames, and this embodiment reframes the target transmission group according to a preset basic frame format to obtain a target basic frame, wherein one basic frame may include multiple target transmission groups corresponding to multiple compression ratios.

[0061] Step S205: Transmitting the target basic frame. Specifically, based on the optical fiber in the digital optical fiber repeater device, the compressed target data is transmitted between the near-end machine and the far-end machine in the form of the target basic frame.

[0062] Through the above steps S201 to S205, the target data to be transmitted is assembled into a plurality of target compression units; according to the different preset compression ratios of the plurality of target compression units, the plurality of target compression units are divided into target compression groups of different categories; wherein, a target compression group includes at least one target compression unit; according to the number of target compression units in each target compression group and the compression ratio corresponding to the target compression group, each target compression group is compressed into a corresponding target transmission group; based on the target transmission group, a target basic frame is constructed; wherein, a target basic frame includes at least one target transmission group; and the target basic frame is transmitted. Related data transmission methods often compress all data to be transmitted according to a fixed compression ratio. Since different data have different characteristics and different requirements for system capacity and transmission performance, a fixed compression ratio will inevitably lead to the inability to meet the system capacity requirements of some data or the inability to meet the transmission performance requirements of some data. The present application sets compression ratios for data classification according to the characteristics and actual needs of the data to be transmitted, compresses them according to their respective compression ratios, and then reframes them. The basic frame of optical fiber transmission can contain multiple groups of data corresponding to different compression ratios. The present application classifies the data and flexibly configures the compression ratio according to the respective requirements of each category of data for system capacity and transmission performance, and then transmits them in a unified manner, thereby solving the problem in related technologies that cannot take into account both system capacity and transmission performance, and taking into account the data's requirements for system capacity and transmission performance.

[0063] In some embodiments, based on the above step S203, compressing each target compression group into a corresponding target transmission group according to the number of target compression units in each target compression group and the compression ratio corresponding to the target compression group may specifically include:

[0064] The compression ratio corresponding to the target compression group is used as the first category identifier of the target compression group; the number of target compression units in the target compression group is used as the second category identifier of the target compression group; the first category identifier and the second category identifier are used as the category identifier of the target compression group; according to the category identifier, the target compression units in each target compression group are compressed to obtain the target transmission group.

[0065] Furthermore, in some embodiments, based on the above step S203, compressing the target compression units in each target compression group according to the category identifier to obtain the target transmission group specifically includes:

[0066] According to the category identifier of the target compression group, each target compression unit within the target compression group is compressed into a target transmission group based on a preset real-time compression algorithm. The real-time compression algorithm can be a Block Floating Point (BFP) compression algorithm. This algorithm does not require pre-storage of a lookup table corresponding to the compressed data; it only requires specifying the compression bit width to complete the data compression algorithm processing. A higher bit width results in less compression noise. The bit width of the target compression unit can be calculated based on the size of the target compression unit and the corresponding compression ratio.

[0067] Furthermore, in some embodiments, based on the above step S204 and based on the target transmission group, constructing a target basic frame may specifically include:

[0068] Based on a preset basic frame format, the target transmission group and corresponding control information are encapsulated into a target basic frame; one target basic frame includes at least one target transmission group. Optical fiber transmission between the near-end and far-end units of a digital optical fiber repeater typically utilizes the CPRI protocol. In some embodiments, based on the basic frame format of the CPRI protocol, a CPRI basic frame is constructed with the control information corresponding to each target transmission group as a frame header and the target transmission group as frame data. The control information includes protocol control information in the form of control words.

[0069] In some embodiments, the control information may also include the number of target transmission units and the compression ratio corresponding to each target transmission group in the target basic frame, i.e., the category identifier of the target compression group corresponding to the target transmission group. Specifically, the category identifier corresponding to each target transmission group in the target basic frame is converted into a control character, and the control character is used as the control information corresponding to the target basic frame. The above-mentioned category identifier is transmitted in the form of a control word in the CPRI basic frame. The receiving end can extract this category identifier information from the CPRI basic frame before decompression and then use this category identifier to decompress the data.

[0070] Furthermore, in some of the embodiments, based on the above step S205, transmitting the target basic frame may specifically include: using multiple optical fibers to transmit the target basic frame.

[0071] Digital fiber optic repeaters utilize light waves as carrier waves and optical fiber as the transmission medium to transmit information from near-end / remote-end to remote / near-end. In related digital fiber optic repeater equipment, both near-end and remote-end devices transmit data via a single optical fiber, resulting in limited transmission capacity and limited flexibility. This embodiment, however, utilizes dual or multiple optical fibers for transmission, expanding transmission capacity. Furthermore, each fiber transmits data independently, enabling the transmission of different carrier information using different compression methods, thereby increasing transmission bandwidth. While using multiple optical fibers for transmission increases bandwidth exponentially, this also requires more physical interfaces and increases data processing complexity. Therefore, in some embodiments, dual-fiber transmission is chosen to strike a balance between transmission capacity and bandwidth, as well as the number of physical interfaces and processing complexity. In actual use, the number of physical optical ports used for fiber optic transmission can be configured based on the environment.

[0072] The present embodiment is described and illustrated below through optional embodiments.
