[0002] The JESD204 standard is a serial data interface and link protocol between data converters and logic devices proposed by the Joint Electron Devices Engineering Council (JEDEC). It transmits frame structure data through a high-speed serial interface, which can effectively save GPIO (General-Purpose Input / Output) pins. Without affecting system performance, it simplifies PCB (Printed Circuit Board) wiring, reduces packaging complexity, and saves PCB manufacturing costs.

[0003] Taking 5G's massive antenna technology as an example, signal transmission and signal receiving devices often have at least 64 antennas, that is, 64 channels. If GPIO pins are used to transmit digital gain compensation information, even if each channel only occupies 3 GPIO pins, at least 192 pins will be occupied, and other control information must be transmitted between the RF transceiver chip and the digital chip, such as low noise amplifier bypass LNA bypass information, channel switch control information, etc. At present, these control information are transmitted separately through GPIO pins, resulting in a large number of GPIO pins interconnected, increasing the complexity of wiring and packaging costs between the RF chip and the digital chip.

[0027] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0028] It should be noted that, although the functional modules are divided in the device schematic diagram and the logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in a different order than the module division in the device or the order in the flowchart. The terms "first", "second", etc. in the specification, claims and the above drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0029] In the description of the embodiments of the present application, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the embodiments of the present application based on the specific content of the technical solution.

[0030] At present, electronic devices transmit information through GPIO pins. However, when multi-channel information needs to be transmitted, each channel requires at least one GPIO pin to transmit information, which will lead to a large number of GPIO pins interconnected. At the same time, taking 5G's large-scale antenna technology as an example, a large amount of control information must be transmitted between the RF transceiver chip and the digital chip, such as automatic gain compensation information, channel switch control information, etc. At present, these control information are transmitted separately through GPIO pins, resulting in a large number of GPIO pins interconnected, which increases the complexity of wiring and packaging costs between the RF chip and the digital chip.

[0031] like Figure 1Take the connection diagram of the RF transceiver chip and the digital chip shown in the figure as an example. The RF transceiver chip and the digital chip are often interconnected by a large number of GPIO pins, which causes the problems of complex PCB, multiple stacking and high cost. In order to solve the above problems, the Joint Electron Device Engineering Committee proposed a serial data interface and link protocol between data converters and logic devices, called the JESD204 standard. As the JESD204 standard evolved over time, the JESD204B and JESD204C standards were gradually added. The above standards support line transmission rates from 1Gb / s to 32Gb / s, and use 64B66B or 8B10B link layer configurations to transmit information instantly and quickly. The module that supports the JESD204 standard is the JESD204 module in the figure. Both the RF transceiver chip and the digital chip have a JESD204 module, which has a serial data interface and can support the JESD204 protocol.

[0032] like Figure 2 As shown in the connection diagram of the GPIO pins for transmitting gain compensation information, for a 4-channel transceiver chip alone, at least 16 GPIO pins need to be interconnected for data transmission. Specifically, the 4 GPIO pins connected to the receiving channel RX1 are GPIO8 to GPIO11 from low data bits to high data bits, and each GPIO pin can transmit 1 bit of information. Taking 5G's large-scale antenna technology as an example, the signal sending and signal receiving devices often have at least 64 antennas, that is, 64 channels, so the GPIO pins used to transmit gain compensation information are as high as 256, which will greatly increase the complexity of wiring.

[0033] Based on this, the embodiments of the present application provide an information encoding method, an information transmission method, an apparatus, a device and a storage medium. Based on the frame structure data of the JESD204 standard, the control information is embedded into the data to be transmitted through encoding, and transmitted through the JESD204 interface, thereby effectively reducing the use of GPIO pins, thereby simplifying the wiring of the PCB, reducing the complexity of the package, and saving manufacturing costs.

[0034] In a first aspect, an embodiment of the present application provides an information encoding method. Figure 3 The following is a flow chart of the information encoding method provided in the embodiment of the present application. Figure 3 As shown, the information encoding method provided by this embodiment at least includes:

[0035] Step S100: Obtain the number of original data bits according to the original data.

[0036] The original data is working data generated by the electronic device. In this embodiment, the original data generated by the data converter is 12 bits or 14 bits.

[0037] Step S200: according to the number of bits of the original data, redundant bits are added to the original data to obtain data to be transmitted.

[0038] The number of data bits to be transmitted is related to the number of original data bits and the number of data bits that can be transmitted as specified by the protocol.

[0039] In this embodiment, based on the JESD204 protocol, the number of data bits to be transmitted is a multiple of 4, which can ensure that all data can be divided into all frames for transmission, and the effective data bits generated by the RF transceiver chip are generally 12 or 14 bits, so it needs to be expanded to 16 bits for data transmission, that is, in this embodiment, the number of data bits to be transmitted is 16 bits.

[0040] The added redundant bits can be determined based on the number of bits of the original data and the number of bits of data to be transmitted. Taking the original data as 14 bits as an example, the extended redundant bits are 2 bits, and converted to I / Q two-way data for transmission, 4 bits are obtained for transmitting control information. Assuming that 3 bits are used to transmit gain compensation information, the maximum control character that can be transmitted is 111, and the corresponding gain compensation information control character is 7. Then, according to the upper limit of the gain compensation information control character, a suitable attenuation step is selected. In this embodiment, the attenuation step corresponding to the 3-bit gain compensation information can be 6dB.

[0041] Those skilled in the art will appreciate that, based on the relationship between the number of original data bits and the number of data bits to be transmitted, the fewer the number of bits used to transmit gain compensation information, the larger the attenuation step that needs to be matched to reduce the number of data bits required for transmission; correspondingly, the more the number of bits used to transmit gain compensation information, the smaller the attenuation step that can be matched to increase the number of data bits required for transmission.

[0042] In the following embodiments, 3-bit gain compensation information and 6 dB attenuation step are used as examples for description.

[0043] Step S300: acquiring the number of character bits of the digital gain compensation information according to the digital gain compensation information.

[0044] The digital gain compensation information is generated by the digital gain compensation module in the RF transceiver chip and is used to compensate for the gain of the analog attenuation of the RF transceiver chip. According to different attenuation steps, the gain compensation information characters and the number of gain compensation information character bits corresponding to the digital gain compensation information are different. Figure 4 In the corresponding embodiment, an exemplary explanation is given for the mapping relationship between the gain compensation information and its control characters.

[0045] Specifically, in this embodiment, the attenuation step is 6dB, so when the attenuation is 0dB, there is no need to expand the bit; when the attenuation is 0-6dB, expand 1 bit; when the attenuation is 6dB-12dB, expand 2 bits; when the attenuation is 12dB-18dB, expand 3 bits.

[0046] Step S400: expanding the data to be transmitted according to the number of character bits of the digital gain compensation information to obtain expanded data.

[0047] The same as the embodiment in steps S100 to S300, the attenuation step is 6dB. Based on this attenuation step, assuming that the analog ATT attenuation value is 14dB, the corresponding digital gain compensation is 14dB. At the same time, it is necessary to expand the data to be transmitted by 3 bits and obtain the expanded data, a total of 19 bits. The expansion of the data to be transmitted can effectively prevent the overflow of the digital gain compensation information.

[0048] Step S500: In the expanded data, data equal to the number of bits of the data to be transmitted is intercepted starting from the high data bits to obtain the truncated data.

[0049] The higher the number of bits of data, the more important the data being transmitted is, that is, the valid data. Therefore, intercepting data equal to the number of bits of data to be transmitted starting from the high data bits can retain the validity of the data to the greatest extent while meeting the transmission conditions.

[0050] As described in the previous step, the expanded data has 19 bits in total, so the first 16 bits need to be intercepted for transmission. The first 16 bits represent intercepting 16 bits in sequence from the high data bits to obtain the truncated data.

[0051] Step S600: inserting control characters into the truncated data to obtain encoded data to be transmitted.

[0052] Since truncation causes data loss, taking the attenuation step of 6dB as an example, if there is no truncation, there will be no loss. At this time, the gain compensation information control character is 0, and the corresponding control character is 000; if 1 bit is truncated, there will be a loss of 6dB, so the gain compensation information control character is 1, and the corresponding control character is 001; if 2 bits are truncated, there will be a loss of 12dB, the gain compensation information control character is 2, and the corresponding control character is 010, and so on.

[0053] The control characters are represented in binary format and inserted into the truncated data, thus completing the entire process of encoding the control information.

[0054] In this embodiment, according to the gain compensation information, the corresponding gain compensation information control character is obtained as 2, which is converted into binary representation as 10. Because the number of bits used to transmit the gain compensation information is 3, the corresponding control character is 010, and 010 is inserted into the truncated data to form the encoded data to be transmitted.

[0055] Theoretically, any control information transmitted between electronic devices can be transmitted by the method described in this embodiment. Specifically, the control information can be gain compensation information, low noise amplifier bypass LNAbypass information, transmission channel TX control information, receiving channel RX control information, etc. The above information can be integrated into the mapping relationship chart between control information and control characters, and the number of control character bits can be determined after binary representation. Accordingly, after decoding to obtain all data with control information, the specific control information is also obtained through the mapping relationship chart between control information and control characters.

[0056] In the above embodiment, by expanding the transmission data according to the number of control information bits, intercepting the valid data containing important information, and inserting the control information therein, it is possible to achieve the effect of transmitting the control information and the valid data together through the serial interface, thereby saving the GPIO pins originally used to transmit the control information, reducing the interconnection of the GPIO pins, and thus simplifying the PCB wiring and reducing the complexity of the package.

[0057] Figure 4 A mapping relationship between digital gain compensation information and control characters provided in another embodiment of the present application.

[0058] Still taking the example of transmitting 3-bit gain compensation information and matching 6dB attenuation step, Figure 4 As shown. According to the analog attenuation information, the digital gain compensation interval is determined, and the corresponding gain compensation information control character is corresponding. When the required digital gain compensation is 0dB, the control character 000 is transmitted; when the required digital gain compensation is within the range of 0dB to 6dB, the control character of the gain compensation information is 1, which is converted into binary as 1, and the control character 001 is transmitted; when the required digital gain compensation is within the range of 6dB to 12dB, the control character of the gain compensation information is 2, which is converted into binary as 10, and the control character 010 is transmitted; and so on, when the required digital gain compensation is within the range of 36dB to 42dB, the control character of the gain compensation information is 7, which is converted into binary as 111, and the control character 111 is transmitted.

[0059] Those skilled in the art can appreciate that other control information, such as low noise amplifier bypass LNAbypass control information, transmission channel TX control information, and reception channel RX control information can all be represented by 0 / 1.

[0060] In one embodiment, for the low noise amplifier bypass LNAbypass control information, when the low noise amplifier LNA has a gain of 10 dB, if the LNAbypass control bit is 1, it indicates bypass; when the LNAbypass control bit is 0, it indicates that the low noise amplifier LNA works normally, that is, generates a gain of 10 dB.

[0061] In another embodiment, the opening and closing of the transmission channel and the reception channel can be indicated by 1 / 0 in the control bit.

[0062] In another embodiment, Figure 5 The mapping relationship between the ATT analog attenuation information, the low noise amplifier bypass LNAbypass control information and the gain compensation information control characters of the RF transceiver chip provided in another embodiment of the present application. Figure 5 As shown, the low noise amplifier bypass LNAbypass control information, the RF transceiver ATT analog attenuation information, and the gain compensation information control characters are integrated into a mapping relationship. When transmitting the control information, on the premise of knowing that the low noise amplifier LNA has a gain of 10dB and the attenuation step is 6dB, the control information corresponding to the attenuation index is sent, and at the decoding end, the control information of the low noise amplifier bypass LNAbypass and the RF transceiver chip gain compensation information are obtained according to the above mapping relationship.

[0063] Figure 6 A mapping relationship between a gain compensation information control character and a transmission control character provided in an embodiment of the present application.

[0064] In the actual data transmission process, two I / Q paths are used, i.e., the in-phase I path and the orthogonal Q path. Therefore, as long as the sum of the control character bits of the two I / Q paths is equal to the total control character bits, it is sufficient. In another embodiment, using 4 control characters can match the attenuation step of less than 6dB, and thus greater gain compensation information, then for the two I / Q paths, each path only needs 2 bits as control character bits to achieve the purpose of carrying complete control information.

[0065] Those skilled in the art should know that the control character bits carried by the two paths may not be equal, that is, the I path may carry 2 bits and the Q path may carry 1 bit.

[0066] Figure 7 A schematic diagram of the process of expanding and truncating bits of an information encoding method provided in another embodiment of the present application.

[0067] like Figure 7As shown, the first row in the figure represents the data to be transmitted, from D0 to D15, a total of 16 bits; the second row in the figure represents the data after expansion, that is, the expansion is performed before the high bit of the data to be transmitted, D+ represents the expansion position, and the expanded data is obtained; the data in the dotted box in the third row of the figure represents the truncated data. Since the data to be transmitted can only transmit 16 bits, 16 bits are sequentially intercepted starting from the high data bit. It can be seen from the figure that the original data D0 is truncated, but because D0 is in a lower position, it does not carry valid information or the information it carries is not important, so being truncated will not affect the overall validity of the data.

[0068] Figure 8 A schematic diagram of the process flow of expanding and truncating bits of an information encoding method provided in yet another embodiment of the present application.

[0069] like Figure 8 As shown in the figure, the first row in the figure represents the data to be transmitted, from D0 to D15, a total of 16 bits; the second row in the figure represents the data after expansion, that is, the expansion is carried out after the low bit of the data to be transmitted, D+ represents the expansion position, and the expanded data is obtained; the data in the dotted box in the third row of the figure represents the truncated data. Since the data to be transmitted can only transmit 16 bits, 16 bits are sequentially intercepted starting from the high data bit. It can be seen from the figure that the two redundant bits originally added are truncated. Based on this situation, if the control information is inserted into the low bit of this truncated data, that is, from D0 to D1, the original D0 and D1 data are deleted and the control information is replaced; if the control information is inserted into the high bit of this truncated data, that is, from D14 to D15, each data bit of the original data is shifted two bits to the right in turn, leaving 2 high bits empty for inserting the control information.

[0070] Therefore, when redundant bits are added to the original data according to the number of control character bits, the redundant bits are added after the low data bits of the original data; when the control characters are inserted into the truncated data, the control characters can be inserted at any position of the truncated data, and any position of the truncated data includes before the high data bit, between the data bits or after the low data bit of the truncated data.

[0071] Fig. 9 A schematic diagram of the control character insertion process of an information encoding method provided in one embodiment of the present application.

[0072] In this embodiment, the control information needs 2 bits to be represented, so the I / Q data can each use 1 bit to represent the control information. Fig. 9 As shown, the upper row represents I-channel data, the lower row represents Q-channel data, SL0 and SL1 represent 2-bit control information respectively, and S represents the positive and negative of the information, that is, the sign bit. Through the information encoding method in this embodiment, the 2-bit control information can be embedded into the data to be transmitted and sent together with the data to be transmitted.

[0073] Fig.10A schematic diagram of the control character insertion process of an information encoding method provided in another embodiment of the present application.

[0074] In this embodiment, the control information needs 4 bits to be represented, so the I / Q data can each use 2 bits to represent the control information. Fig.10 As shown, the upper row represents I-channel data, the lower row represents Q-channel data, SL0 and SL1 represent 2-bit control information in I-channel respectively, SL2 and SL3 represent 2-bit control information in Q-channel respectively, and S represents the positive and negative of the information, that is, the sign bit. Through the information encoding method in this embodiment, the 4-bit control information can be embedded into the data to be transmitted and sent together with the data to be transmitted.

[0075] The above two embodiments embed the control information into the data to be transmitted and transmit them together through the JESD204 interface, thereby saving the GPIO pins originally used to transmit the control information and reducing the interconnection of the GPIO pins, thereby simplifying the PCB wiring and reducing the complexity of the package.
