Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a communication method and related systems and storage media. Background Art

[0002] Traditional source-channel separation coding is difficult to satisfy the assumption of unlimited code length in Shannon separation theorem in actual communication systems, so it is necessary to study the source-channel joint coding system. In a complete source-channel joint coding system, the input signal is encoded by the encoder at the transmitter, and the encoded code stream reaches the receiver through the channel. The receiver decodes the noisy code stream to restore the signal.

[0003] The rise of deep networks in recent years has also brought new breakthroughs in the field of traditional coding, and research on source-channel joint coding based on deep learning has also achieved good results. The source-channel joint coding system based on deep learning uses different deep networks as encoders and decoders respectively. Among them, the deep source-channel joint coding scheme for distributed sources deploys encoder networks with the same structure in two related but non-interconnected sources at the transmitter. However, since the two source encoders transmit different code streams to the receiver during training, the returned gradients are also different, and the parameters of the two after training are also different. The deep source-channel joint coding scheme for distributed sources splices the two different code streams received at the receiver and reconstructs them through a joint decoder.

[0004] However, although this scheme uses the cross-attention mechanism to extract the received correlation at the receiving end, the sending end does not use the correlation between the sources at all. The sent data still has a lot of redundancy, which wastes bandwidth and affects the reconstruction performance. Summary of the invention

[0005] The present application discloses a communication method and a related system and storage medium, which can reduce the sending of redundant data when sending data and save transmission resources.

[0006] In a first aspect, an embodiment of the present application provides a communication method. The method may be performed by a communication device, or by a component of a communication device (e.g., a chip (system)). The method may include:

[0008] A second code stream is sent to the network device, where the second code stream is obtained based on a second information source, the first code stream, and the reconstructed first perturbation coefficient, and a dimension of the second code stream is smaller than a dimension of the second information source.

[0009] In an embodiment of the present application, based on the first block division result of the first information source fed back by the network device and the reconstructed disturbance coefficient, the communication device can obtain the image distribution information of the first information source, and then based on the image distribution information of the first information source and the second information source, the correlation between the distributed information sources can be more effectively extracted to reduce transmission redundancy.

[0013] Processing is performed based on the second information source and the third disturbance coefficient to obtain the second code stream.

[0014] In this example, a third disturbance coefficient is obtained based on the second information source and the reconstructed second disturbance coefficient. The dimension of the third disturbance coefficient is smaller than the dimension of the second information source, which can reduce redundant data transmission.

[0015] In a possible implementation manner, the method further includes: receiving first information from the network device, where the first information indicates a first partitioning scheme, and the first partitioning scheme corresponds to the first block partitioning result;

[0016] The obtaining the first block division result based on the first code stream includes:

[0017] The first block division result is obtained based on the first division scheme and the first code stream.

[0018] In this example, based on the indication information of the network device, the partitioning scheme can be known, and then the first partitioning result can be reconstructed.

[0019] In a second aspect, an embodiment of the present application provides a communication method. The method may be performed by a communication device, or by a component of a communication device (e.g., a chip (system)). The method may include:

[0033] A first code stream and a reconstructed first disturbance coefficient are sent to a second terminal, where the first code stream includes the first block division result, the reconstructed first disturbance coefficient is obtained based on the first block division result and the fourth code stream, and the reconstructed first disturbance coefficient represents the distribution characteristics of the first information source.

[0034] In this example, the network device processes based on the third code stream and the fourth code stream from the first terminal, and sends the first code stream containing the first block division result and the reconstructed first perturbation coefficient that characterizes the distribution characteristics of the first information source to the second terminal. This facilitates the second terminal to process based on the second information source, the first code stream and the reconstructed first perturbation coefficient, and removes the redundant data in the second information source with the first information source to obtain the second code stream, so that the second terminal can obtain the image distribution information of the first information source, and then more effectively extract the correlation between the distributed information sources and reduce transmission redundancy.

[0035] In this example, the network device can build a bridge of information communication between related information sources through the feedback mechanism to fully utilize the relevant information between the information sources. By feeding back the disturbance coefficient, the correlation between the information sources can be fully utilized at a lower transmission cost.

[0036] In a possible implementation, the method further includes:

[0048] The second terminal sends a second code stream to the network device, where the second code stream is obtained based on a second information source, the first code stream and the reconstructed first perturbation coefficient, and a dimension of the second code stream is smaller than a dimension of the second information source.

[0049] In an embodiment of the present application, the first terminal sends a third code stream containing the first block division result corresponding to the first information source to the network device, and also sends a fourth code stream obtained by scrambling the first block division result. The network device processes based on the third code stream and the fourth code stream, and sends the first code stream containing the first block division result and the reconstructed first disturbance coefficient characterizing the distribution characteristics of the first information source to the second terminal. In this way, the second terminal processes based on the second information source, the first code stream and the reconstructed first disturbance coefficient, and obtains the second code stream after removing the redundant data with the first information source in the second information source. Then the network device reconstructs the first information source and the second information source based on the fourth code stream and the second code stream. In this way, the network device feeds back the first block division result of the first information source and the reconstructed disturbance coefficient to the second terminal, so that the second terminal can obtain the image distribution information of the first information source, and then more effectively extract the correlation between the distributed information sources and reduce transmission redundancy.

[0107] The following describes the embodiments of the present application in conjunction with the drawings in the embodiments of the present application. The terms used in the implementation method part of the embodiments of the present application are only used to explain the specific embodiments of the present application, and are not intended to limit the present application.

[0108] The following will describe in detail the system architecture of the embodiment of the present application in conjunction with the accompanying drawings. Figure 1 FIG. 1 is a schematic diagram of an application scenario of a communication system provided in an embodiment of the present application. The communication system may include a terminal 101 and a network device 102 .

[0109] Among them, the terminal 101 can also be called a terminal device, a user equipment (UE), a mobile station, a mobile terminal, etc. The terminal can be widely used in various scenarios, for example, device-to-device (D2D), vehicle to everything (V2X) communication, machine-type communication (MTC), Internet of Things (IOT), virtual reality, augmented reality, industrial control, automatic driving, telemedicine, smart grid, smart furniture, smart office, smart wear, smart transportation, smart city, etc. The terminal can be a mobile phone, a tablet computer, a computer with wireless transceiver function, a wearable device, a vehicle, a drone, a helicopter, an airplane, a ship, a robot, a mechanical arm, a smart home device, etc. The embodiments of the present application do not limit the specific technology and specific device form adopted by the terminal. The embodiments of the present application do not limit the number of terminals 101.

[0110] The network device 102 may be a base station, an evolved NodeB (eNodeB), a transmission reception point (TRP), a next generation NodeB (gNB) in a fifth generation (5G) mobile communication system, a next generation base station in a sixth generation (6G) mobile communication system, a base station in a future mobile communication system, or an access node in a WiFi system, etc.; it may also be a module or unit that completes some functions of a base station, for example, a centralized unit (CU) or a distributed unit (DU). The network device 102 may be a macro base station, a micro base station or an indoor station, a relay node or a donor node, etc. The embodiments of the present application do not limit the specific technology and specific device form adopted by the network device 102. For ease of description, the following description takes a base station as an example of a network device.

[0111] Base stations and terminals can be fixed or movable. Base stations and terminals can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; they can also be deployed on the water surface; they can also be deployed on aircraft, balloons, and artificial satellites in the air. The embodiments of this application do not limit the application scenarios of base stations and terminals.

[0112] Base stations and terminals, base stations and base stations, and terminals and terminals can communicate through authorized spectrum, unauthorized spectrum, or both; they can communicate through spectrum below 6 gigahertz (GHz), spectrum above 6 GHz, or spectrum below 6 GHz and spectrum above 6 GHz. The embodiments of the present application do not limit the spectrum resources used for wireless communication.

[0113] In the embodiments of the present application, the functions of the base station may also be performed by a module (such as a chip) in the base station, or by a control subsystem including the base station function. The control subsystem including the base station function here may be a control center in the above-mentioned application scenarios such as smart grid, industrial control, smart transportation, and smart city.

[0114] This scheme can be widely used in wireless communication systems with distributed source-channel joint coding, including future cellular, Wi-Fi and other communication systems, to support data compression and transmission in distributed scenarios.

[0115] The architecture of the embodiment of the present application is described above, and the method of the embodiment of the present application is described in detail below.

[0116] Reference Figure 2 FIG. 1 is a flow chart of a communication method provided in an embodiment of the present application. Optionally, the method can be applied to the aforementioned communication system, for example Figure 1 The communication system shown in FIG. Figure 2 The communication method shown may include steps 201-208. It should be understood that for the convenience of description, this application is described in the order of 201-208, and is not intended to limit the execution to the above order. The embodiment of the present application does not limit the execution order, execution time, execution number, etc. of the above one or more steps. The following description takes the execution subject of steps 201-202 of the communication method as the first terminal UE1, the execution subject of steps 203-204, 207-208 as the network device, and the execution subject of steps 205-206 as the second terminal UE2 as an example. This application is also applicable to other execution subjects. Steps 201-208 are as follows:

[0117] 201. A first terminal processes a first information source to obtain a first block division result corresponding to the first information source.

[0118] It can be understood that the information source in the embodiments of the present application may be an image, video, etc., and this solution does not impose any limitation on this.

[0119] The first terminal processes the first information source by performing block division processing on the first information source. For example, the first information source is divided into a plurality of blocks of the same or different sizes. This is done so that the distribution information inside the image can be used more effectively later. It is understandable that the first block division result may include the results of the plurality of blocks obtained by the division.

[0120] In a possible implementation, step 201 may include:

[0121] The first terminal obtains a second disturbance coefficient corresponding to the first information source. Further, the first terminal performs block division processing based on the second disturbance coefficient to obtain a first block division result corresponding to the first information source.

[0122] The second disturbance coefficient is used to indicate the distribution characteristics of the first information source. The second disturbance coefficient can be obtained by inputting the first information source into a preset neural network for processing.

[0123] 202. The first terminal sends a third code stream and a fourth code stream to a network device, where the third code stream includes the first block division result, and the fourth code stream is obtained by scrambling the first block division result.

[0124] Exemplarily, the first terminal performs block pooling merging processing based on the first block division result and the second perturbation coefficient to obtain the first perturbation coefficient. Furthermore, the first terminal performs scrambling processing on the first information source based on the first perturbation coefficient to obtain the fourth code stream.

[0125] The first disturbance coefficient represents the distribution characteristics of the first information source. It can be understood that the first disturbance coefficient includes multiple coefficients of multiple sub-blocks, and each coefficient represents the characteristics of a corresponding area in a corresponding sub-block.

[0126] The above-mentioned block pooling merging process can be understood as performing average pooling processing on each block in the first block division result (that is, calculating the average of the elements in the block).

[0127] By dividing the image corresponding to the first information source into blocks of different sizes and applying disturbances to each of them, the distribution information inside the image can be more effectively utilized.

[0128] In a possible implementation, the first terminal sends the third code stream to the network device via a digital transmission mode, and sends the fourth code stream to the network device via an analog transmission mode.

[0129] 203. The network device receives the third code stream and the fourth code stream from the first terminal.

[0130] 204. The network device sends a first code stream and a reconstructed first disturbance coefficient to a second terminal, where the first code stream includes the first block division result, the reconstructed first disturbance coefficient is obtained based on the first block division result and the fourth code stream, and the reconstructed first disturbance coefficient represents a distribution characteristic of the first information source.

[0131] The network device can obtain a first block division result by decoding the received third code stream. The network device processes the received fourth code stream and the first block division result obtained by decoding to obtain a reconstructed first disturbance coefficient.

[0132] Exemplarily, the network device inputs the received fourth bitstream into the reconstruction network to obtain the reconstructed second disturbance coefficient, and then performs block pooling and merging processing on the reconstructed second disturbance coefficient according to the first block division result to obtain the reconstructed first disturbance coefficient.

[0133] In a possible implementation, the first terminal further sends information to the network device, the information indicating a first partitioning scheme, the first partitioning scheme corresponding to the first block partitioning result. That is, the first terminal informs the network device which block partitioning scheme it adopts, so that the network device and the second terminal can restore the first block partitioning result.

[0134] Exemplarily, the block division scheme may be a two-classification scheme, a four-classification scheme, etc. The two-classification scheme is to divide the block into two sub-blocks, each of which may also include a different division scheme. For the introduction of this part, please refer to the records of the subsequent embodiments, which will not be repeated here.

[0135] Furthermore, the network device receives the information from the first terminal, and decodes and recovers the third code stream based on the indication to obtain a first block division result.

[0136] Of course, the indication of the division scheme may also be the configuration of the network device, etc., and this scheme does not impose any limitation on this.

[0137] In this example, the network device can build a bridge of information communication between related information sources through the feedback mechanism to fully utilize the relevant information between the information sources. By feeding back the disturbance coefficient, the correlation between the information sources can be fully utilized at a lower transmission cost.

[0138] 205. The second terminal receives the first code stream and the reconstructed first disturbance coefficient from the network device.

[0139] 206. The second terminal sends a second code stream to the network device, where the second code stream is obtained based on a second information source, the first code stream, and the reconstructed first perturbation coefficient, and a dimension of the second code stream is smaller than a dimension of the second information source.

[0140] The second terminal performs processing based on the second information source, the first code stream and the reconstructed first disturbance coefficient, and obtains a second code stream after removing data in the second information source that is redundant with the first information source, wherein the dimension of the second code stream is smaller than the dimension of the second information source.

[0141] In a possible implementation manner, the second terminal obtains the first block division result based on the first code stream; and then obtains the reconstructed second perturbation coefficient based on the first block division result and the reconstructed first perturbation coefficient.

[0142] Furthermore, the second terminal obtains a third disturbance coefficient based on the second information source and the reconstructed second disturbance coefficient, wherein the third disturbance coefficient represents the distribution characteristics of the second information source, and the dimension of the third disturbance coefficient is smaller than the dimension of the second information source.

[0143] The second terminal performs processing based on the second information source and the third perturbation coefficient to obtain the second code stream. Exemplarily, the second terminal sends the second code stream in an analog transmission manner.

[0144] In a possible implementation, the network device further sends information to the second terminal to indicate the first partitioning scheme. Further, the second terminal receives the information from the network device and obtains the first block partitioning result based on the first partitioning scheme and the first code stream.

[0145] The network device informs the second terminal which block partitioning scheme is so that the second terminal can restore the first block partitioning result.

[0146] 207. The network device receives a second code stream from the second terminal.

[0147] 208. The network device performs processing based on the fourth code stream and the second code stream to obtain the reconstructed first information source and the reconstructed second information source.

[0148] The network device splices the fourth code stream sent by the first terminal and the second code stream sent by the second terminal in the channel dimension and inputs them into the joint decoder for reconstruction to obtain a reconstructed first information source and a reconstructed second information source.

[0149] In an embodiment of the present application, the first terminal sends a third code stream containing the first block division result corresponding to the first information source to the network device, and also sends a fourth code stream obtained by scrambling the first block division result. The network device processes based on the third code stream and the fourth code stream, and sends the first code stream containing the first block division result and the reconstructed first disturbance coefficient characterizing the distribution characteristics of the first information source to the second terminal. In this way, the second terminal processes based on the second information source, the first code stream and the reconstructed first disturbance coefficient, and obtains the second code stream after removing the redundant data with the first information source in the second information source. Then the network device reconstructs the first information source and the second information source based on the fourth code stream and the second code stream. In this way, the network device feeds back the first block division result of the first information source and the reconstructed disturbance coefficient to the second terminal, so that the second terminal can obtain the image distribution information of the first information source, and then more effectively extract the correlation between the distributed information sources and reduce transmission redundancy.

[0150] Reference Figure 3 , Figure 4 FIG. 1 is a flow chart of another communication method provided in an embodiment of the present application. Optionally, the method can be applied to the aforementioned communication system, for example Figure 1 The communication system shown in FIG. Figure 3The communication method shown may include steps 301-308. It should be understood that for the convenience of description, this application is described in the order of 301-308, and is not intended to limit the execution to the above order. The embodiment of the present application does not limit the order of execution, execution time, number of executions, etc. of the above one or more steps. The following description takes the execution subject of steps 301, 304, 305 and 308 of the communication method as a base station, the execution subject of 302 and 303 as UE1, and the execution subject of 306 and 307 as UE2 as an example. This application is also applicable to other execution subjects. Steps 301-308 are as follows:

[0151] 301. The base station indicates information about the selected block partitioning scheme to UE1.

[0152] Exemplarily, the base station selects an appropriate block partitioning scheme based on the current channel state and a pre-determined signal to interference plus noise ratio (SINR) threshold T. When the channel state is better (SINR>T), a more complex block partitioning scheme (such as Figure 5 The dynamic-4 four-classification scheme shown in the figure divides the source into four blocks, namely M0, M1, M2 and M3). Otherwise, a simple block partitioning scheme (such as Figure 5 The dynamic-2 two-classification scheme shown divides the information source into two blocks, namely M0 and M1), and indicates the block division scheme information.

[0153] 302. UE1 extracts block partition result 1 and source 1 perturbation coding bit stream.

[0154] UE1 receives the block division scheme information sent by the base station, and then processes the information source 1 to obtain the block division result of the information source 1 and the disturbance coding code stream of the information source 1.

[0155] Combination Figure 4 , UE1 inputs the original source 1 into the dynamic block partitioning perturbation module, and obtains the source 1 block partitioning result and the perturbed source 1 for the original source 1. Then, UE1 inputs the perturbed source 1 into the encoder 1 of the Joint Source and Channel Coding (JSCC) (implementing the JSCC function of the Joint Source and Channel Coding) to obtain the coded code stream of the perturbed source 1. Among them, UE1 simulates the transmission of the coded code stream of the perturbed source 1. UE1 sends the source 1 block partitioning result through digital transmission.

[0156] In one possible implementation, Figure 6As shown, the dynamic block partitioning perturbation module includes a perturbation network 1, a block partitioning network 1, a block pooling module and a perturbation module. UE1 may perform perturbation coding processing including steps S1-S4:

[0157] S1 and UE1 input the original source 1 (which can be expressed as x1) into the perturbation network 1, and obtain the perturbation coefficient 1 to be combined (which can be expressed as p1, that is, Figure 2 The second disturbance coefficient in the illustrated embodiment).

[0158] For example, Figure 7a As shown, it is a schematic diagram of the structure of a perturbation network provided in an embodiment of the present application. The network includes three consecutive convolution Conv-generalized divisive normalization (Generalized Divisive Normalization, GDN)-parametric linear rectifier function (PReLU) modules, and finally passes through a convolution layer to obtain the output. The input of the network is the original source 1 (which can be expressed as x1∈R h×w×3 ), the output is the disturbance coefficient to be merged 1 (which can be expressed as ). Exemplarily, two convolutional downsampling layers with a stride of 2 are used here, so k=4.

[0159] S2. UE1 inputs the disturbance coefficient 1 to be merged (which can be expressed as p1) into the block partitioning network 1, and obtains the block partitioning result 1 (which can be expressed as k1) corresponding to each disturbance coefficient.

[0160] like Figure 7b As shown, it is a schematic diagram of the structure of a block partitioning network provided by an embodiment of the present application. The network includes three groups of Conv-PReLU layers, and the second layer uses a residual connection structure. After passing through the convolution layer, the activation function Softmax layer outputs the classification probability of N-classifications, where N is determined by the transmitting end (UE1) or the receiving end (base station), and N is the number of block divisions. The network input is the disturbance coefficient to be merged 1 (i.e. ) and N, after passing through the Softmax layer, the output is the block division result 1 (which can be expressed as ).

[0161] S3, UE1 performs uniform pooling and merging processing on the disturbance coefficient 1 to be merged in the block pooling module according to the block division result 1, and obtains the disturbance coefficient 1 (which can be expressed as t1, that is, Figure 2 The first disturbance coefficient in the illustrated embodiment).

[0162] like Figure 7c The block pooling module provided in the embodiment of the present application is shown in FIG. ) and block partition result 1 (i.e. ). In this example, one classification result corresponds to 2x2 perturbation coefficients. Then, according to the classification scheme corresponding to N-classification in the dynamic partitioning scheme library, the corresponding perturbation coefficient of each classification result is divided into blocks of different sizes (taking 4-classification as an example: 2x2 blocks can be divided into four types: 1x1, 1x2, 2x1 and 2x2). Each block is merged by average pooling to obtain the merged perturbation coefficient 1.

[0163] S4. UE1 samples the disturbance coefficient 1 (which can be expressed as t1) as the variance from the Gaussian distribution in the disturbance module, applies Gaussian additive noise to the original source 1 for disturbance, and obtains the disturbance source 1 (which can be expressed as d1).

[0164] Among them, according to the block division result 1k1, the original source 1x1 is divided into several different blocks, and the disturbance of each block is set to obey the same Gaussian distribution, from the Gaussian distribution N(0,t1) determined by the disturbance coefficient t1 i ) in random sampling (N(μ,σ 2 ) represents a Gaussian distribution with a mean of μ and a standard deviation of σ), and it is added to the position corresponding to the original source to obtain the disturbed source 1d1.

[0165] d1 i =x1 i +n i ,n i ~N(0,t1 i )

[0166] Where i is the data number in the original source 1, n i is the corresponding superimposed random Gaussian perturbation.

[0167] UE1 encodes the disturbance source 1 to obtain the disturbance encoding code stream of source 1. For example, Figure 7d The figure shows a schematic diagram of a deep network of an encoder 1 provided in an embodiment of the present application. The input of the network is an image source d1∈R h×w×3 , the output of the network is the encoded bit stream The encoder network has a total of 4 consecutive Conv-GDN-PReLU modules, followed by a convolutional layer.

[0168] 303. UE1 sends block division result 1 and source 1 disturbance coding code stream information to the base station.

[0169] UE1 uses analog transmission to send source 1 disturbance coded code stream information (i.e. Figure 2 The fourth code stream in the embodiment shown).

[0170] UE1 also processes the block division result 1 using channel coding (such as low-density parity check (LDPC), polarization code, etc.) and quadrature amplitude modulation (QAM) modulation, and sends the modulated signal (i.e. Figure 8a The digital code stream 1 shown, that is, Figure 2 The third code stream in the illustrated embodiment).

[0171] 304. The base station obtains the reconstructed disturbance coefficient 1 (i.e. Figure 2 The reconstructed first perturbation coefficient in the illustrated embodiment).

[0172] like Figure 4 As shown, the base station processes the received block division result 1 and the source 1 disturbance coding code stream information to obtain the reconstructed disturbance coefficient 1, and transmits it to UE2 in analog. The base station also transmits the block division result 1 to UE2 in digital.

[0173] Specifically, Figure 8a As shown, the base station obtains the block division result 1k1 by digital transmission decoding (such as channel decoding and QAM demodulation) of the digital code stream 1, and then performs digital transmission encoding again and sends it to UE2.

[0174] The base station also receives the perturbation code stream 1 (which can be expressed as That is, the received source 1 disturbance coded code stream) is input into the reconstruction network 1, and the restored disturbance coefficient to be merged 1 is obtained (which can be expressed as ). The base station performs a merging process on the recovered disturbance coefficient 1 to be merged in the block pooling module according to the block division result 1k1, and obtains the reconstructed disturbance coefficient 1 (which can be expressed as That is, the reconstructed first disturbance coefficient), and transmits it to UE2.

[0175] like Figure 8b As shown, it is a schematic diagram of the structure of a reconstruction network provided in an embodiment of the present application. The reconstruction network 1 includes 4 consecutive deconvolution layer modules, each module includes transposed convolution / deconvolution (Transposed Convolution, TConv)-generalized divisive normalization inverse operation (Inverse Generalized Divisive Normalization, IGDN)-PReLU, and the output of the last deconvolution module will pass through another deconvolution layer output (i.e., the top network unit). The network input is the noisy code stream sent by the received UE1 (i.e., the perturbation coded code stream of source 1 ), the output is the restored disturbance coefficient to be merged 1 (which can be expressed as ).

[0176] 305. The base station sends block partition result 1 and reconstruction disturbance coefficient 1 to UE2.

[0177] 306. UE2 extracts the disturbance coded bit stream of source 2.

[0178] UE2 receives the disturbance coefficient 1 according to the block division result 1k1 fed back by the base station. Copy the upsampling to get the reconstructed perturbation coefficient 1 (Right now Figure 2 The reconstructed second disturbance coefficient in the illustrated embodiment).

[0179] Then, UE2 combines the original source 2 (expressed as x2) with the reconstructed perturbation coefficient 1 The channel dimension is spliced ​​and sent to the dynamic block partitioning perturbation module to obtain the block partitioning result 2k2 and the perturbation source 2d2 for the original source 2.

[0180] UE2 sends the disturbance source 2d2 to encoder 2 to obtain the encoded bit stream y2 of the disturbance source 2.

[0181] UE2 simulates the transmission disturbance source 2 and encodes the bit stream y2.

[0182] For example, Fig. 9 As shown, the input of the dynamic block partitioning perturbation module is the original source 2 (which can be expressed as x2∈R h×w×3 ), the reconstruction disturbance coefficient fed back by the base station 1 And block partition result 1 First, it uses the block partition result 1k1 fed back by the base station to reconstruct the received disturbance coefficient 1 Copy the upsampled image to reconstruct the disturbance coefficient to be merged 1 Then the original source 2x2 is reconstructed with the disturbance coefficient 1 to be combined Concatenate in the channel dimension to get f2∈R j ×w×4 Then, the spliced ​​f2 is sent to the dynamic block division perturbation module to obtain the block division result 2k2 and the perturbation source 2d2 for the original source 2. UE2 sends the perturbation source 2d2 to encoder 2 to obtain the encoded bit stream of perturbation source 2 UE2 simulates the transmission disturbance source 2 and encodes the bit stream y2.

[0183] Specifically, the concatenated f2 is input into the perturbation network 2 for processing to obtain the perturbation coefficient 2 to be merged. Block division processing is performed based on the perturbation coefficient 2 to be merged to obtain the block division result 2. The perturbation coefficient 2 to be merged and the block division result 2 are both input into the block pooling module for processing to obtain the perturbation coefficient 2 (i.e. Figure 2Based on the disturbance coefficient 2, Gaussian additive noise is applied to the original information source 2 to disturb it, so as to obtain a disturbance information source 2 of the original information source 2.

[0184] It can be understood that the network structure may be consistent with the network structure adopted by the aforementioned UE1, and this solution does not impose any limitation on this.

[0185] 307. UE2 sends the disturbance coding code stream information of source 2 to the base station.

[0186] 308. The base station obtains reconstructed information source 1 and information source 2.

[0187] like Fig.10 The figure is a schematic diagram of a joint decoder network structure provided by an embodiment of the present application. The base station uses a joint decoder to reconstruct each signal source. The module first receives and Concatenate to get joint input Then it is fed into the joint decoder network to reconstruct its output and That is, the reconstructed information source 1 and the reconstructed information source 2 are obtained.

[0188] For example, when the joint decoder network is trained, all networks are trained end-to-end, and the loss function Loss can be expressed as:

[0189]

[0190] in, and The corresponding items represent the reconstruction losses of the two sources, The corresponding term represents the reconstruction loss of the perturbation coefficient of source 1, and α and λ are weight factors.
