[0087] In the related art, the CSI reported by the terminal to the network side includes two parts. The first part includes: rank indication (RI), channel quality indication (CQI) and the number of non-zero broadband amplitude coefficients in the broadband amplitude W2. The second part is used to report: the indication information of the broadband feedback W1, the sub-band amplitude corresponding to the non-zero broadband amplitude of W2 and the sub-band phase corresponding to the non-zero broadband amplitude. The two parts of the CSI are independently coded. In the CSI reported by the terminal, the number of bits in the first part is fixed, and the number of bits in the second part is variable. The RI in the first part and the number of non-zero broadband amplitude coefficients in W2 can determine the number of bits in the second part. The network side can demodulate the information bits of the second part according to the information in the first part.

[0088] Although the relevant technology defines a scheme for segmenting CSI and configuring the transmission mode, this scheme is implemented based on a clear physical meaning. However, the CSI compression method based on the AI ​​model is quite different from the current compression method based on the CSI feature vector. After the CSI bit stream compressed by the AI ​​model is segmented, it does not have a clear physical meaning like the existing CSI feedback system. For example, when the system directly uses the AI ​​model to feedback the full channel information, the RI and CQI (CSI part 1) mentioned above cannot be distinguished, and the importance of each part of the CSI cannot be judged, so it is impossible to select a suitable transmission method for the segmented CSI bit stream, and the CSI bit error rate is high.

[0089] Based on this, in various embodiments of the present application, the network device sends configuration information to the terminal, and the configuration information is used to configure the grouping mode of the compressed CSI bit stream and / or related information of the bit group; the terminal receives the configuration information sent by the network device, and based on the configuration information, divides the compressed CSI bit stream into multiple bit groups, and determines the first information, and the first information indicates the transmission mode and / or transmission priority of each bit group in the multiple bit groups. In the above scheme, the terminal can group the compressed CSI bit stream based on the configuration information, and configure a suitable transmission mode and / or transmission priority for each bit group. Thus, the terminal can configure different transmission modes and / or transmission priorities for different bit groups, which can reduce the bit error rate of CSI, and can reduce the transmission overhead as much as possible while reducing the performance loss caused by bit errors during the transmission process.

[0090] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0091] The present application embodiment provides an information transmission method, such as Figure 1 As shown, the method includes:

[0092] Step 101: Receive configuration information sent by a network device.

[0093] The configuration information is used to configure the grouping mode of the compressed CSI bit stream and / or related information of the bit group.

[0094] Here, the configuration information may be carried in a radio resource control (RRC) signaling, or a media access control layer (MAC) control element (CE), and may also be carried in other signaling. The relevant information of the bit group may be the relevant information used to transmit the bit group.

[0095] In order to facilitate the terminal to group the compressed CSI bit stream and determine the transmission mode of each bit group, in one embodiment, the configuration information includes at least one of the following:

[0096] second information, wherein the second information indicates a transmission quality requirement;

[0097] third information indicating the number of bit groups of the compressed CSI bit stream and the number of bits contained in each bit group;

[0098] fourth information indicating a weight of each bit group;

[0099] The fifth information indicates a transmission mode supported by the bit group.

[0100] Here, the second information and / or the fourth information can be used for the terminal to determine the transmission mode of the bit group to reduce the bit error rate. Among them, the transmission modes of the bit group belong to the set of transmission modes supported by the bit group configured by the network device; one transmission mode corresponds to one transmission reliability, and the transmission reliability of different transmission modes can be the same or different. The transmission quality requirement indicated by the second information is for all bit groups, and the second information may include the bit error rate and / or the transmission rate. The fourth information may include the weight of each bit group. The fifth information may include the transmission modes supported by the bit group, and all bit groups may support the same transmission mode or at least two different transmission modes.

[0101] The third information may include the number of bit groups and the number of bits contained in each bit group, and the third information is used for the terminal to group the compressed CSI bit stream. Since the third information indicates the number of bit groups of the compressed CSI bit stream and the number of bits contained in each bit group, grouping the compressed CSI bit stream based on the third information can improve grouping efficiency.

[0102] In order to diversify the transmission mode and facilitate the terminal to flexibly configure the transmission mode of the bit group, in one embodiment, the transmission mode indicates the corresponding relationship between at least two of the coding mode, the number of layers and the modulation mode.

[0103] Here, the number of layers is related to the rank of the channel matrix; the rank value of the channel matrix is ​​used to indicate how many independent channels there are between the terminal and the network device. In actual transmission, generally not all independent channels are used. The number of independent channels used is the number of layers, which is also called Layer.

[0104] The coding method includes polar coding and / or low density parity check code (LDPC). The modulation method includes quadrature amplitude modulation (QAM), and QAM may include 16QAM and / or 64QAM.

[0105] Table 1 gives examples of transmission modes, and there is a corresponding relationship between the transmission modes and the transmission priorities.

[0106] Table 1

[0107] Encoding Number of layers Modulation Priority Transmission method 1 Polarization Code <![CDATA[L1]]> <![CDATA[Q1]]> Transfer priority 1 Transmission method 2 LDPC <![CDATA[L2]]> <![CDATA[Q2]]> Transfer priority 2 Transmission method 3 LDPC <![CDATA[L3]]> <![CDATA[Q3]]> Transfer priority 3 ··· ··· ··· ··· ···

[0108] Among them, each transmission mode corresponds to a transmission priority, and different transmission modes have different transmission reliability. In Table 1, transmission priority 1 has the highest priority, transmission priority 2 has a lower priority than transmission priority 1, and transmission priority 3 has a lower priority than transmission priority 2; the transmission reliability of transmission mode 1 is greater than the transmission reliability of transmission mode 2, and the transmission reliability of transmission mode 2 is greater than the transmission reliability of transmission mode 3.

[0109] For example, transmission mode 1 may indicate that the coding mode is polar code, the number of layers is 1, and the modulation mode is 16QAM, and the transmission mode 1 corresponds to the transmission priority 1 (the highest transmission priority); transmission mode 2 may indicate that the coding mode is LDPC, the number of layers is 1, and the modulation mode is 16QAM, and the transmission mode 2 corresponds to the transmission priority 2 (the second priority); transmission mode 3 may indicate that the coding mode is LDPC, the number of layers is 2, and the modulation mode is 64QAM, and the transmission mode 3 corresponds to the transmission priority 3 (the third priority).

[0110] It should be noted that transmission mode 1 can ensure higher channel quality and lower inter-code interference during the transmission process, but transmission mode 1 requires more transmission resources; transmission mode 2 or transmission mode 3 can avoid occupying too many transmission resources while ensuring basic transmission quality.

[0111] Step 102: Based on the configuration information, the compressed CSI bit stream is divided into a plurality of bit groups, and first information is determined.

[0112] The first information indicates a transmission mode and / or a transmission priority of each bit group in the multiple bit groups.

[0113] Here, the terminal obtains a compressed CSI bit stream, divides the compressed CSI bit stream into multiple bit groups based on the grouping mode of the compressed CSI bit stream indicated by the configuration information, and determines the transmission mode and / or transmission priority of each bit group based on the relevant information of the bit group indicated by the configuration information. Figure 2 As shown, the terminal divides the compressed CSI bit stream into n bit groups based on the configuration information, and allocates a corresponding transmission mode to each bit group in the n bit groups. The implementation process of the terminal obtaining the compressed CSI bit stream may be: the terminal receives a channel state information reference signal (CSI-RS, Channel State Information-Reference Signal) sent by a network device; performs CSI measurement using the received CSI-RS to obtain the measured CSI; and compresses the measured CSI to obtain a compressed CSI bit stream.

[0114] Specifically, when the configuration information includes the third information, the compressed CSI bit stream is divided into multiple bit groups based on the number of bit groups indicated by the third information and the number of bits contained in each bit group; the number of bits contained in different bit groups may be the same or different.

[0115] In the case where the configuration information includes the second information, the transmission mode of each bit group is determined based on the transmission quality requirement indicated by the second information. In practical applications, in the case where the second information includes the bit error rate, since the bit group with less information can allow a higher bit error rate, and the bit group with more information can allow a lower bit error rate, the terminal can configure a transmission mode with higher reliability for the bit group with more information, and a transmission mode with lower reliability for the bit group with less information, so as to ensure the transmission quality, for example, to ensure that most of the CSI information is not lost, and avoid occupying too many transmission resources. In the case where the second information includes the transmission rate, the terminal can configure a transmission mode corresponding to a lower transmission priority for the bit group with a higher transmission rate, and configure a transmission mode corresponding to a higher transmission priority for the bit group with a lower transmission rate.

[0116] In the case where the configuration information includes the fourth information, the transmission mode of each bit group is determined based on the weight of each bit group indicated by the fourth information. For a bit group with a higher weight, a transmission mode with a higher reliability can be configured to ensure that the bit group with a higher weight has a higher channel quality and lower inter-symbol interference during the transmission process, thereby preserving most of the CSI information from being lost; for a bit group with a lower weight, a transmission mode with a lower reliability can be configured to avoid occupying too many transmission resources on the basis of ensuring the transmission quality.

[0117] In the case where the configuration information includes the fifth information, the transmission mode supported by the bit group is determined based on the fifth information. The transmission mode configured by the terminal for each bit group belongs to the transmission mode supported by the bit group indicated by the fifth information.

[0118] Since the bit group with higher weight is more important or contains more information, in order to reduce the bit error rate of the bit group with larger weight as much as possible and improve the transmission reliability of the bit group with larger weight, in one embodiment, when the weight of the first bit group is greater than the weight of the second bit group, the reliability of the transmission mode of the first bit group is higher than the reliability of the transmission mode of the second bit group, and / or the transmission priority of the first bit group is higher than the transmission priority of the second bit group.

[0119] Here, the terminal may determine the transmission priority of each bit group based on the fourth information, and determine the transmission mode of each bit group based on the transmission priority of each bit group and the correspondence between the transmission priority and the transmission mode.

[0120] For example, when the number of bit groups is 4, if the transmission reliabilities corresponding to transmission mode 1, transmission mode 2 and transmission mode 3 in Table 1 decrease in sequence, and the weights corresponding to bit group 1, bit group 2 and bit group 3 decrease in sequence, and the weight of bit group 3 is the same as the weight of bit group 4, then the terminal can configure transmission mode 1 for bit group 1, transmission mode 2 for bit group 2, and transmission mode 3 for both bit group 3 and bit group 4.

[0121] In order to configure a suitable transmission mode for each bit group and save transmission resources as much as possible while ensuring transmission reliability, in one embodiment, determining the first information includes at least one of the following:

[0122] determining a transmission priority of each bit group based at least on the second information and the fourth information;

[0123] Based on a first relationship, a transmission mode corresponding to the transmission priority of each bit group is determined; the first relationship includes a correspondence between the transmission priority and the transmission mode.

[0124] Here, the terminal compares the value of the indicator corresponding to the transmission quality requirement indicated by the second information with the set threshold to obtain a comparison result; based on the weight of each bit group indicated by the fourth information and the priority configuration rule matching the comparison result, the transmission priority of each bit group is determined. Among them, the number of thresholds is set to at least one. The allocation of transmission priority can be very flexible, and each bit group can correspond to a transmission priority, or multiple bit groups can correspond to the same transmission priority.

[0125] For example, in the case where the second information includes transmission rate and / or bit error rate, if the transmission rate is higher and / or the bit error rate is higher, the terminal configures a lower transmission priority for the bit group with a larger weight, and the transmission priority of most bit groups is lower; if the transmission rate is lower and / or the bit error rate is lower, the terminal configures a higher transmission priority for the bit group with a larger weight, and the transmission priority of most bit groups is higher.

[0126] In order to configure a suitable transmission mode for each bit group according to different transmission quality requirements, in one embodiment, determining the transmission priority of each bit group based on at least the second information and the fourth information includes:

[0127] determining a first score based on the second information;

[0128] Based on the fourth information, determine a second score and a third score; wherein the second score represents the score corresponding to the weight of the i bit groups, and the third score represents the score corresponding to the weight of the i+1 bit groups, where i is a positive integer;

[0129] When the second score is less than or equal to the first score, and / or the third score is greater than the first score, the same transmission priority of the i bit groups corresponding to the second score is determined.

[0130] Here, in the case where the second information includes a transmission rate and / or a bit error rate, the first score is determined based on the following formula:

[0131]

[0132] Among them, copoint represents the first score, β and γ are both configured coefficients, R represents the transmission rate, and BER represents the bit error rate.

[0133] The terminal determines the weight of each bit group in the multiple divided bit groups based on the fourth information; determines the score corresponding to the weight of the i bit group based on the set coefficient and the weights of the i bit groups in the multiple divided bit groups, and obtains the second score; determines the score corresponding to the i+1 bit group based on the set coefficient and the weights of the i+1 bit groups in the multiple divided bit groups, and obtains the third score.

[0134] In order to accurately determine the second score and the third score, in one embodiment, the second score is determined based on the sum of the set coefficient and the weights of the i bit groups;

[0135] The third score is determined based on the sum of the set coefficient and the weights of the i+1 bit groups.

[0136] Here, the second score represents the product of the sum of the weights of the i bit groups and the first set coefficient, and the third score represents the product of the sum of the weights of the i+1 bit groups and the first set coefficient. Determine the second score and the third score; where Score n The scores corresponding to the weights of n bit groups are represented, where n=i when determining the second score and n=i+1 when determining the third score; i is a positive integer and is less than the total number of bit groups; α represents a setting coefficient; λn represents the weight of the nth bit group.

[0137] When the terminal determines the first score, the second score, and the third score, it determines whether the second score is less than or equal to the first score, and determines whether the third score is greater than the first score; when at least one of the following is satisfied, it is determined that the i bit groups corresponding to the second score correspond to the same transmission priority:

[0138] The second score is less than or equal to the first score;

[0139] The second score is less than or equal to the first score, and the third score is greater than the first score.

[0140] When the second score is less than or equal to the first score, and the third score is less than or equal to the first score, i is incremented by 1; thereafter, the second score and the third score are re-determined based on the fourth information, and subsequent steps are performed until any of the above conditions is met.

[0141] It should be noted that the i bit groups or i+1 bit groups are determined in sequence according to the arrangement order of the divided multiple bit groups. After determining the transmission priorities of the i bit groups, the terminal determines the transmission priorities of the remaining bit groups in sequence.

[0142] Figure 3 An example of configuring transmission priorities for multiple bit groups is shown, such as Figure 3 As shown, the terminal divides n bit groups, the weights of bit group 1 and bit group 2 are higher, and the weights of bit group 3 to bit group 5 are lower. The terminal determines the second score based on the weight of bit group 1 and the weight of bit group 2; determines the third score based on the weights of bit group 1 to bit group 3; when the second score is less than or equal to the first score, and the third score is less than or equal to the first score, the terminal configures transmission priority 1 for both bit group 1 and bit group 2. Then, the terminal determines the second score based on the weights of bit group 3 to bit group 5, and determines the third score based on the weights of bit group 3 to bit group 6. When the second score is less than or equal to the first score, and the third score is less than or equal to the first score, the terminal configures transmission priority 2 for bit group 3 to bit group 5. According to this method, the transmission priorities of all the remaining bit groups are determined in sequence.

[0143] In the embodiment of the present application, Score n Infinitely close to copoint, and Score n Less than or equal to copoint, so that in the scenario of higher transmission rate and / or higher bit error rate, lower transmission priority is configured for more bit groups as much as possible; in the scenario of lower transmission rate and / or lower bit error rate, higher transmission priority is configured for more bit groups as much as possible. n Without exceeding copoint, as many bit groups as possible are first included in the transmission priority 1; n As many bit groups as possible are then transferred to transmission priority 2 without exceeding the copoint, and so on.

[0144] After dividing the plurality of bit groups, the terminal needs to send the bit groups to the network device so that the network device obtains the CSI. Based on this, in one embodiment, the method further includes at least one of the following:

[0145] Based on the first information, sending the plurality of bit groups to the network device;

[0146] The first information is sent to the network device.

[0147] Here, since the first information can indicate the transmission mode and / or transmission priority of each bit group in multiple bit groups, the terminal can determine the sending order of all bit groups based on the transmission priority of each bit group; based on the sending order of all bit groups, the terminal can send the corresponding bit group to the network device according to the transmission mode of each bit group.

[0148] In which, when the transmission mode indicates a correspondence between at least two of the coding mode, the number of layers and the modulation mode, the terminal can encode the bit group using the coding mode indicated by the transmission mode, modulate the bit group using the modulation mode indicated by the transmission mode, and determine the number of channels used by the terminal based on the number of layers indicated by the transmission mode.

[0149] The terminal sends the first information to the network device, so that the network device can decode and / or demodulate the received bit group based on the first information to obtain the correct CSI.

[0150] Correspondingly, the embodiment of the present application also provides an information transmission method, which is applied to a network device, wherein the network device includes a base station, such as Figure 4 As shown, the method includes:

[0151] Step 401: Send configuration information to the terminal.

[0152] The configuration information is used to configure the grouping mode and / or related information of the compressed CSI bit stream and / or the bit group, and the configuration information is used for the terminal to group the compressed CSI bit stream and determine the transmission mode and / or transmission priority of each bit group.

[0153] Here, the configuration information sent by the network device to different terminals may be the same or different.

[0154] In one embodiment, the method further comprises:

[0155] The configuration information is obtained.

[0156] Here, the configuration information may be preconfigured, determined in real time, or acquired from other devices.

[0157] In order to facilitate the terminal to group the compressed CSI bit stream and determine the transmission mode of each bit group, in one embodiment, the configuration information includes at least one of the following:

[0158] second information, wherein the second information indicates a transmission quality requirement;

[0159] third information indicating the number of bit groups of the compressed CSI bit stream and the number of bits contained in each bit group;

[0160] fourth information indicating a weight of each bit group;

[0161] The fifth information indicates a transmission mode supported by the bit group.

[0162] In order to make the weights of different bit groups have obvious differences or be not completely the same, and to improve the accuracy of the weights of the bit groups, in one embodiment, obtaining the configuration information includes:

[0163] Acquire the fourth information determined by the first model; wherein,

[0164] The first model is used to determine the weight of each bit group of the input.

[0165] Here, the first model can be obtained by training the network device or other terminals based on the compressed CSI bit stream. The compressed CSI bit stream used to train the first model is different from the bit stream compressed in step 102.

[0166] In one embodiment, the first model is trained by the following method:

[0167] Decompressing the N third bit groups contained in the first bit stream by the first model to obtain N first CSIs and N second CSIs; wherein one third bit group corresponds to one first CSI, a bit combination corresponding to one third bit group corresponds to one second CSI, and one bit combination contains at least one third bit group; N is a positive integer greater than or equal to 2;

[0168] Determine the second weights of the N third bit groups based on the N second CSIs and the third CSIs, and based on the first weights of the N third bit groups; wherein the third CSI represents the calibrated CSI corresponding to the first bit stream; and the first weight represents the initial weight of the configuration or the second weight in the previous round of iterative training;

[0169] Determine a total loss value based on the N first CSIs and the third CSI, and based on second weights of the N third bit groups;

[0170] Based on the second weights of the N third bit groups and / or the total loss value, the first model is trained until the set convergence condition is reached; wherein the second weights of the N third bit groups are used to determine the fourth information, or to update the first weights.

[0171] Here, the first bit stream can be divided into N third bit groups based on the third information. The first bit stream is a compressed CSI bit stream, and the first bit stream is different from the bit stream compressed in step 102; the N third bit groups are input into the first model for decompression to obtain N first CSIs and N second CSIs. Among them, the N first CSIs are obtained by decompressing the N third bit groups respectively, and one third bit group corresponds to one first CSI; the N second CSIs are obtained by decompressing N bit combinations (combinations of bit groups) of different lengths, and one bit combination contains at least one third bit group; the bit combination corresponding to any third bit group includes at least the third bit group, and may also include at least one third bit group located before the third bit group; in the process of iterative training of the first model, the number of third bit groups contained in the bit combination corresponding to the third bit group can be changed. Figure 5 As shown, in actual application, the bit combination corresponding to any third bit group includes the third bit group and all third bit groups located before the third bit group, so that the front bit groups in the first CSI bit stream can obtain higher weights.

[0172] When N second CSIs are obtained, the first loss value of each second CSI in the N second CSIs is determined based on the difference between each second CSI in the N second CSIs and the third CSI; the second weight of each third bit group in the N third bit groups is determined based on the first loss value of the N second CSIs and the first weight of the N third bit groups.

[0173] When N first CSIs are obtained, the second loss value of each of the N first CSIs is determined based on the difference between each of the N first CSIs and the third CSI; the total loss value is determined based on the second loss values ​​of the N first CSIs and the second weights of the N third bit groups; the first model is trained based on the second weights of the N third bit groups and / or the total loss value until the set convergence condition is reached, and the training is stopped to obtain the first model after the training is completed.

[0174] For example, the set convergence conditions may include that the total loss value is less than or equal to a set threshold value, and / or that the number of training times reaches a set number of times. When the total loss value is less than or equal to the set threshold value, and / or the number of training times reaches a set number of times, back propagation is performed in the first model based on the total loss value, and in the process of back propagation, the model parameters of the first model are updated, and the first model after the updated model parameters is used as the first model after the training is completed, and the fourth information is generated by the weights of the N third bit groups. When the total loss value is greater than the set threshold value, and / or the number of training times is less than the set number of times, after updating the model parameters of the first model, the first weights of the N third bit groups are updated correspondingly based on the second weights of the N third bit groups, and the next iterative training is performed until the set convergence conditions are reached.

[0175] In an embodiment of the present application, the weight of the third bit group can be continuously updated during the training of the first model, so that the amount of CSI information contained in different bit groups can be significantly different, so that the third bit group with a larger amount of information obtains a higher weight, thereby improving the accuracy of the weight of each bit group indicated by the fourth information.

[0176] The weight of the third bit group can be continuously updated during the training of the first model, so that the weight of the bit group finally obtained is more accurate. Based on this, in one embodiment, after determining the second weights of the N third bit groups, the method further includes:

[0177] Based on the second weights of the N third bit groups, the first weight of each third bit group is correspondingly updated to the second weight.

[0178] Here, the first weight of any third bit group is replaced or updated with the second weight of the third bit group, so that in the next round of iterative training, the second weight and the total loss value of the third bit group are re-determined using the updated weight of the third bit group.

[0179] In order to accurately determine the second weight of each third bit group, in one embodiment, determining the second weights of the N third bit groups based on the N second CSIs and the third CSIs, and based on the first weights of the N third bit groups, includes:

[0180] determining a first loss value of the third bit group based on the third CSI and the second CSI corresponding to the third bit group;

[0181] Based on the first loss value of the third bit group and the corresponding first weight, a second weight of the third bit group is determined.

[0182] Here, the second weight of any third bit group can be determined in the following manner: based on the difference between the third CSI and the second CSI corresponding to the third bit group, determine the first loss value of the third bit group; based on the first loss value of the third bit group and the corresponding first weight, determine the second weight of the third bit group.

[0183] In actual application, the second weight of the third bit group is determined according to the following formula:

[0184]

[0185] in, The second weight representing the i-th third bit group; λ i Characterizes the first weight of the i-th third bit group; Loss i Characterizes the first loss value of the i-th third bit group; Norm(λ i +Loss i ) characterizes the pair (λ i +Loss i ) is normalized, and the normalization formula can be

[0186] In the embodiment of the present application, the characteristic that the longer the length of the bit combination is, the more accurate the output result of the first model is and the smaller the total loss value is is utilized. Therefore, the above-mentioned method of updating the weights can enable the front bit groups in the first bit stream to obtain higher weights, so that the front bit groups can learn more CSI information.

[0187] In order to improve the accuracy of the first model, thereby improving the accuracy of the weight of each bit group indicated by the fourth information determined by the first model, in one embodiment, determining the total loss value based on the N first CSIs and the third CSI, and based on the second weights of the N third bit groups, includes:

[0188] Determine second loss values ​​of N third bit groups based on the N first CSIs and the third CSI;

[0189] The total loss value is determined based on the second weight of each third bit group in the N third bit groups and the corresponding second loss value.

[0190] Here, based on the difference between each first CSI and the third CSI in the N first CSIs, the second loss value of the third bit group corresponding to the first CSI is determined; based on the second weight of each third bit group in the N third bit groups and the corresponding second loss value, the total loss value is determined.

[0191] In practical application, the following formula is used to determine the total loss value:

[0192]

[0193] Among them, Lossσ represents the total loss value; loss i Characterizes a second loss value of the i-th third bit group.

[0194] Figure 6 An example of simulation verification results is given for dividing the first bit stream into 2 bit groups. Figure 7 An example of simulation verification results is given in which the first bit stream is divided into three bit groups. The vertical axis in the simulation graph is cosine similarity, and the higher the cosine similarity of the bit group, the higher the recovery accuracy of the bit group, and the more information contained in the bit group. Figure 6 (a) and Figure 7 (a) is the simulation verification result of the cosine similarity of each bit group when the first model is trained without considering the weight of the bit group, Figure 6 (b) and Figure 7 (b) is a simulation verification result of the cosine similarity of each bit group when the first model is trained considering the weight of the bit group, that is, a simulation verification result of the loss value when the first model is trained according to the above method. Figure 7 Among them, the cosine similarity of the CSI restored by the third bit group 1 is the highest, the cosine similarity of the CSI restored by the third bit group 2 is the second, and the cosine similarity of the CSI restored by the third bit group 3 is the smallest, and the loss value of the third bit group 3 is the smallest. Figure 6 and Figure 7 It can be seen that the first model trained by the embodiment of the present application can allocate the information in the CSI to the third bit group 1, the third bit group 2 and the third bit group 3 in order from most to least.

[0195] After the terminal sends multiple bit groups to the network device, the network device receives the multiple bit groups sent by the terminal and obtains CSI based on the received multiple bit groups. Based on this, in one embodiment, the method further includes:

[0196] receiving a plurality of bit groups and / or first information sent by the terminal, where the first information indicates a transmission mode and / or a transmission priority of each bit group in the plurality of bit groups, and the transmission priority of the bit group is used to determine the transmission mode of the bit group;

[0197] Based on the transmission mode corresponding to each bit group in the multiple bit groups, the multiple bit groups are processed to obtain processing results.

[0198] Here, since there is a corresponding relationship or mapping relationship between the transmission priority and the transmission mode, the network device can determine the transmission mode corresponding to the transmission priority of the bit group based on the corresponding relationship between the transmission priority and the transmission mode.

[0199] When the network device receives all the bit groups sent by the terminal, it processes the bit group based on the transmission mode corresponding to the bit group, such as decoding and / or demodulating the bit group, to obtain a processing result; sorts and concatenates the processing results of each bit group to obtain a complete CSI bit stream; and decompresses the complete CSI bit stream to obtain CSI.

[0232] When the second score is less than or equal to the first score, and / or the third score is greater than the first score, the same transmission priority of the i bit groups corresponding to the second score is determined.
