[0087] In related technologies, the CSI reported by the terminal to the network side consists of two parts. The first part includes: Rank Indication (RI), Channel Quality Indicator (CQI), and the number of non-zero broadband amplitude coefficients in the broadband amplitude W2. The second part is used to report: indication information of broadband feedback W1, the subband amplitude corresponding to the non-zero broadband amplitude of W2, and the subband 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, while the number of bits in the second part is variable. The number of bits in the second part can be determined by the RI in the first part and the number of non-zero broadband amplitude coefficients in W2. The network side can demodulate the information bits in the second part based on the information in the first part.

[0088] While related technologies define schemes for segmenting CSI and configuring transmission methods, these schemes are based on explicit physical meanings. However, CSI compression methods based on AI models differ significantly from current compression methods based on CSI feature vectors. After segmentation, the CSI bitstream compressed using AI models does not have explicit physical meanings like existing CSI feedback systems. For example, when the system directly uses AI models to feed back full-channel information, the RI and CQI (CSI part 1) mentioned above cannot be distinguished, making it impossible to determine the importance of each part of the CSI. Consequently, it is impossible to select an appropriate transmission method for the segmented CSI bitstream, resulting in a high bit error rate for CSI.

[0089] Based on this, in various embodiments of this application, the network device sends configuration information to the terminal. This configuration information is used to configure the grouping method and / or related information of the compressed CSI bitstream. The terminal receives the configuration information from the network device and, based on the configuration information, divides the compressed CSI bitstream into multiple bit groups, and determines first information, which indicates the transmission method and / or transmission priority of each bit group. In this scheme, the terminal can group the compressed CSI bitstream based on the configuration information and configure a suitable transmission method and / or transmission priority for each bit group. Therefore, the terminal can configure different transmission methods and / or transmission priorities for different bit groups, which can reduce the bit error rate of CSI and minimize transmission overhead while reducing performance loss caused by bit errors during transmission.

[0090] The present application will now be described in further detail with reference to the accompanying drawings and embodiments.

[0091] This application provides an information transmission method, such as... Figure 1 As shown, the method includes:

[0092] Step 101: Receive configuration information from the network device.

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

[0094] Here, configuration information can be carried in Radio Resource Control (RRC) signaling, or in Media Access Control (MAC) control elements (CE), or in other signaling. The information related to the bit group can be information used to transmit the bit group.

[0095] To facilitate the terminal in grouping compressed CSI bitstreams and determining the transmission method for each bit group, in one embodiment, the configuration information includes at least one of the following:

[0096] The second information indicates the transmission quality requirements;

[0097] The third information indicates the number of bit groups in the compressed CSI bitstream and the number of bits contained in each bit group;

[0098] The fourth information indicates the weight of each bit group;

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

[0100] Here, the second and / or fourth information can be used by the terminal to determine the transmission method of the bit group in order to reduce the bit error rate. The transmission methods of the bit group all belong to the set of transmission methods supported by the bit group configured by the network device; each transmission method corresponds to a transmission reliability, and different transmission methods may have the same or different transmission reliability. The transmission quality requirements indicated by the second information are for all bit groups, and the second information may include the bit error rate and / or transmission rate. The fourth information may include the weight of each bit group. The fifth information may include the transmission methods supported by the bit group; all bit groups may support the same transmission method or at least two different transmission methods.

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

[0102] To diversify transmission methods and facilitate flexible configuration of bit groups by the terminal, in one embodiment, the transmission method indicates the correspondence between at least two of the encoding method, number of layers, and modulation method.

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

[0104] The encoding methods include polar code encoding and / or low-density parity-check code (LDPC). The modulation methods include quadrature amplitude modulation (QAM), which can include 16QAM and / or 64QAM.

[0105] Table 1 provides examples of transmission methods, and there is a corresponding relationship between transmission methods and transmission priorities.

[0106] Table 1

[0107] Encoding method number of floors Modulation method Priority Transmission Method 1 Polar codes <![CDATA[L1]]> <![CDATA[Q1]]> Transmission priority 1 Transmission Method 2 LDPC <![CDATA[L2]]> <![CDATA[Q2]]> Transmission priority 2 Transmission Method 3 LDPC <![CDATA[L3]]> <![CDATA[Q3]]> Transmission priority 3 ··· ··· ··· ··· ···

[0108] Each transmission method corresponds to a transmission priority, and the transmission reliability varies depending on the transmission method. 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 method 1 is greater than that of transmission method 2, and the transmission reliability of transmission method 2 is greater than that of transmission method 3.

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

[0110] It should be noted that transmission method 1 can guarantee higher channel quality and lower inter-symbol interference during transmission, but it requires more transmission resources; transmission method 2 or transmission method 3 can ensure basic transmission quality while avoiding excessive use of transmission resources.

[0111] Step 102: Based on the configuration information, divide the compressed CSI bitstream into multiple bit groups and determine the first information.

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

[0113] Here, the terminal obtains the compressed CSI bitstream, divides it into multiple bit groups based on the grouping method of the compressed CSI bitstream indicated by the configuration information, and determines the transmission method and / or transmission priority of each bit group based on the relevant information of the bit groups indicated by the configuration information. For example... Figure 2 As shown, the terminal divides the compressed CSI bitstream into n bit groups based on configuration information and assigns a corresponding transmission mode to each of the n bit groups. The process by which the terminal obtains the compressed CSI bitstream can be as follows: the terminal receives a Channel State Information-Reference Signal (CSI-RS) from the network device; performs CSI measurement using the received CSI-RS to obtain the measured CSI; and compresses the measured CSI to obtain the compressed CSI bitstream.

[0114] Specifically, when the configuration information includes third information, the compressed CSI bitstream 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 can be the same or different.

[0115] When the configuration information includes the second information, the transmission mode for each bit group is determined based on the transmission quality requirements indicated by the second information. In practical applications, when the second information includes the bit error rate, since bit groups with less information can tolerate a higher bit error rate, while bit groups with more information can tolerate a lower bit error rate, the terminal can configure a more reliable transmission mode for bit groups with more information and a less reliable transmission mode for bit groups with less information. This ensures transmission quality, such as preventing the loss of most CSI information, while avoiding excessive consumption of transmission resources. When the second information includes the transmission rate, the terminal can configure a lower transmission priority mode for bit groups with higher transmission rates and a higher transmission priority mode for bit groups with lower transmission rates.

[0116] When the configuration information includes the fourth information, the transmission mode for each bit group is determined based on the weight of each bit group indicated by the fourth information. Specifically, for bit groups with higher weights, a more reliable transmission mode can be configured to ensure that the bit groups with higher weights have higher channel quality and lower inter-symbol interference during transmission, thereby preserving most of the CSI information. For bit groups with lower weights, a less reliable transmission mode can be configured to ensure transmission quality while avoiding excessive consumption of transmission resources.

[0117] If the configuration information includes the fifth piece of information, the transmission mode supported by the bit group is determined based on the fifth piece of 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 piece of information.

[0118] Since the higher the weight of a bit group, the more important it is or the more information it contains, in order to minimize the bit error rate of the bit group with a larger weight and improve the transmission reliability of the bit group with a 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 can 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, if the transmission reliability of transmission mode 1, transmission mode 2 and transmission mode 3 in Table 1 decreases sequentially, and the weights of bit group 1, bit group 2 and bit group 3 decrease sequentially, and the weight of bit group 3 is the same as that 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 method 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] Based at least on the second information and the fourth information, the transmission priority of each bit group is determined;

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

[0124] Here, the terminal compares the value of the indicator corresponding to the transmission quality requirement indicated by the second information with a 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, it determines the transmission priority of each bit group. The number of set thresholds is at least one. The allocation of transmission priorities can be very flexible; each bit group can correspond to a different transmission priority, or multiple bit groups can correspond to the same transmission priority.

[0125] For example, if the second information includes transmission rate and / or bit error rate, then if the transmission rate is higher and / or the bit error rate is higher, the terminal will configure a lower transmission priority for bit groups with larger weights, and most bit groups will have a lower transmission priority; if the transmission rate is lower and / or the bit error rate is lower, then the terminal will configure a higher transmission priority for bit groups with larger weights, and most bit groups will have a higher transmission priority.

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

[0127] The first score is determined based on the second information;

[0128] Based on the fourth information, the second score and the third score are determined; wherein, the second score represents the score corresponding to the weight of the i-th bit group, and the third score represents the score corresponding to the weight of the (i+1)-th bit group, where i is a positive integer;

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

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

[0131]

[0132] Where 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 bit groups based on the fourth information; based on the set coefficients and the weights of the i bit groups in the multiple bit groups, it determines the score corresponding to the weights of the i bit groups, and obtains the second score; based on the set coefficients and the weights of the (i+1) bit groups in the multiple bit groups, it determines the score corresponding to the (i+1) 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 a set coefficient and the sum of the weights of the i-bit groups;

[0135] The third score is determined based on the sum of the set coefficients and the weights of the (i+1)th bit group.

[0136] Here, the second score represents the product of the sum of the weights of the i-th bit groups and the first predetermined coefficient, and the third score represents the product of the sum of the weights of the (i+1)-th bit groups and the first predetermined coefficient. In practical applications, the terminal can be based on... Determine the second and third scores; where Score n The score represents the weight of the n bit groups. When determining the second score, n = i, and when determining the third score, n = i + 1. i is a positive integer and less than the total number of bit groups. α represents the set coefficient. λn represents the weight of the nth bit group.

[0137] Given a first score, a second score, and a third score, the terminal determines whether the second score is less than or equal to the first score, and whether the third score is greater than the first score. If at least one of the following conditions is met, the terminal determines that the i bit groups corresponding to the second score belong 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] If 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; then, the second and third scores are re-determined based on the fourth information, and subsequent steps are performed until either of the above conditions is met.

[0141] It should be noted that the i-th bit group or i+1-th bit group is determined sequentially according to the arrangement order of the multiple bit groups. After determining the transmission priority of the i-th bit group, the terminal determines the transmission priority 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 the data into n bit groups, with bit groups 1 and 2 having higher weights and bit groups 3 through 5 having lower weights. Based on the weights of bit groups 1 and 2, the terminal determines a second score; based on the weights of bit groups 1 through 3, it determines a third score. If 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 assigns a transmission priority of 1 to both bit groups 1 and 2. Then, the terminal determines a second score based on the weights of bit groups 3 through 5, and a third score based on the weights of bit groups 3 through 6. If 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 assigns a transmission priority of 2 to both bit groups 3 through 5. This process is repeated to determine the transmission priorities of all remaining bit groups.

[0143] In this embodiment of the application, Score can be n Infinitely close to copoint, and Score n The priority should be less than or equal to copoint, thus allowing for the allocation of lower transmission priority to as many bit groups as possible in scenarios with higher transmission rates and / or higher bit error rates; conversely, in scenarios with lower transmission rates and / or lower bit error rates, allowing for the allocation of higher transmission priority to as many bit groups as possible. For example, while ensuring Score... n Without exceeding the copoint limit, prioritize as many bit groups as possible into transmission priority 1; while ensuring the score... n Without exceeding the copoint limit, then include as many bit groups as possible in transmission priority 2, and so on.

[0144] After the terminal divides the data into multiple bit groups, it needs to send the bit groups to the network device so that the network device can obtain the CSI. Based on this, in one embodiment, the method further includes at least one of the following:

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

[0146] Send the first information to the network device.

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

[0148] Where the transmission mode indicates a correspondence between at least two of the coding method, the number of layers, and the modulation method, the terminal can encode the bit group using the coding method indicated by the transmission mode, modulate the bit group using the modulation method 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 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, embodiments of this application also provide an information transmission method applied to a network device, the network device including 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 method and / or related information of the compressed CSI bit stream. The configuration information is used by the terminal to group the compressed CSI bit stream and determine the transmission method and / or transmission priority of each bit group.

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

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

[0155] Obtain the configuration information.

[0156] Here, the configuration information can be pre-configured, determined in real time, or obtained from other devices.

[0157] To facilitate the terminal in grouping compressed CSI bitstreams and determining the transmission method for each bit group, in one embodiment, the configuration information includes at least one of the following:

[0158] The second information indicates the transmission quality requirements;

[0159] The third information indicates the number of bit groups in the compressed CSI bitstream and the number of bits contained in each bit group;

[0160] The fourth information indicates the weight of each bit group;

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

[0162] To ensure that the weights of different bit groups are significantly different or not completely identical, and to improve the accuracy of the bit group weights, in one embodiment, obtaining the configuration information includes:

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

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

[0165] Here, the first model can be trained by a network device or other terminal based on a compressed CSI bitstream. The compressed CSI bitstream used to train the first model is different from the compressed bitstream in step 102.

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

[0167] The first bitstream is decompressed using the first model to obtain N first CSIs and N second CSIs; wherein, one third bit group corresponds to one first CSI, one 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] Based on N second CSIs and third CSIs, and based on the first weights of N third bit groups, the second weights of the N third bit groups are determined; wherein, the third CSI represents the calibration CSI corresponding to the first bit stream; the first weight represents the configured initial weights or the second weights in the previous iteration training.

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

[0170] 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 met; 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 bitstream can be divided into N third bit groups based on the third information. The first bitstream is a compressed CSI bitstream, which is different from the compressed bitstream in step 102. The N third bit groups are input into the first model for decompression, resulting in N first CSIs and N second CSIs. The N first CSIs are obtained by decompressing the N third bit groups respectively, with one third bit group corresponding to one first CSI. The N second CSIs are obtained by decompressing N combinations of bits (combinations of bit groups) of different lengths, with each bit combination containing at least one third bit group. Any bit combination corresponding to a third bit group must include at least that third bit group, and may also include at least one third bit group preceding it. During iterative training of the first model, the number of third bit groups contained in the bit combination corresponding to a third bit group can be changed. Figure 5 As shown, in practical applications, the bit combination corresponding to any third bit group includes that third bit group and all third bit groups located before that bit group, which allows the bit groups at the beginning of the first CSI bit stream to receive higher weights.

[0172] Given N second CSIs, a first loss value is determined for each of the N second CSIs based on the difference between each second CSI and the third CSI; and a second weight is determined for each of the N third bit groups based on the first loss value of the N second CSIs and the first weight of the N third bit groups.

[0173] Given N first CSIs, a second loss value is determined for each of the N first CSIs based on the difference between each first CSI 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 met, at which point training stops, and the first model is obtained after training is completed.

[0174] For example, the convergence conditions may include a total loss value less than or equal to a set threshold, and / or, the number of training iterations reaching a set number. If the total loss value is less than or equal to the set threshold, and / or the number of training iterations reaches the set number, backpropagation is performed on the first model based on the total loss value. During backpropagation, the model parameters of the first model are updated, and the first model with updated model parameters is used as the first model after training ends. Fourth information is generated from the weights of N third bit groups. If the total loss value is greater than the set threshold, and / or the number of training iterations is less than the set number, after updating the model parameters of the first model, the first weights of the N third bit groups are updated based on the second weights of the N third bit groups, and the next iteration of training is performed until the set convergence conditions are met.

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

[0176] During the training of the first model, the weights of the third bit group can be continuously updated to make the final weights of the bit groups 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 weights of each third bit group are updated to the corresponding second weights.

[0178] Here, the first weight of any third bit group is replaced or updated with the second weight of that third bit group, so that in the next round of training iteration, the second weight of the third bit group and the total loss value can be redetermined using the updated weight of the third bit group.

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

[0180] Based on the third CSI and the second CSI corresponding to the third bit group, determine the first loss value of the third bit group;

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

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

[0183] In practical applications, 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 The first weight representing the i-th third bit group; Loss i The first loss value representing the i-th third bit group; Norm(λ) i +Loss i Characterize the pair (λ) i +Loss i Normalization is performed, and the formula for normalization is as follows:

[0186] In this embodiment, the longer the bit combination, the more accurate the output of the first model and the smaller the total loss value. Therefore, the above-mentioned method of updating weights can enable the first bit group in the first bit stream to obtain higher weights, so that the first bit group can learn more CSI information.

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

[0188] Based on the N first CSIs and the third CSI, determine the second loss value of the N third bit groups;

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

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

[0191] In practical applications, the total loss value is determined using the following formula:

[0192]

[0193] Where Lossσ represents the total loss value; loss i The second loss value represents the i-th third bit group.

[0194] Figure 6 An example of simulation verification results is given by dividing the first bitstream into two bit groups. Figure 7 An example of simulation verification results is given, showing the first bitstream divided into three bit groups. In the simulation graph, the vertical axis represents cosine similarity; a higher cosine similarity indicates higher recovery accuracy and more information contained within that bit group. Figure 6 (a) and Figure 7 (a) is the simulation verification result of the cosine similarity of each bit group when training the first model without considering the weights of the bit groups. Figure 6 (b) and Figure 7 (b) is the simulation verification result of the cosine similarity of each bit group when training the first model considering the weight of the bit group, that is, the simulation verification result of the loss value when training the first model according to the above method. Figure 7 Among them, the CSI recovered by the third bit group 1 has the highest cosine similarity, followed by the CSI recovered by the third bit group 2, and the CSI recovered by the third bit group 3 has the lowest cosine similarity, with the third bit group 3 having the smallest loss value. (Comparison) Figure 6 and Figure 7 It is understood that the first model trained in the embodiments of this application can allocate the information in CSI to the third bit group 1, the third bit group 2 and the third bit group 3 in order of more or less.

[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 the CSI based on the received multiple bit groups. Therefore, in one embodiment, the method further includes:

[0196] Receive multiple bit groups and / or first information sent by the terminal, wherein the first information indicates the transmission mode and / or transmission priority of each bit group in the multiple 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 method corresponding to each of the multiple bit groups, the multiple bit groups are processed to obtain the processing result.

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

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