That is, the coding auxiliary information may include only the first auxiliary information, the second auxiliary information or the third auxiliary information, or may include the first auxiliary information and the second auxiliary information, or may include the first auxiliary information, the second auxiliary information and the third auxiliary information, and so on. Among them, the first auxiliary information is channel-related information, the second auxiliary information is CSI feedback accuracy information, and the third auxiliary information is background information of the transmitter and / or the receiver.

[0053] Step 22: The transmitting end encodes the CSI to be transmitted according to the coding auxiliary information to obtain second information.

[0054] In some embodiments, different types of CSI may be encoded based on coding auxiliary information.

[0055] In some embodiments, when encoding the CSI to be transmitted according to the first auxiliary information, the transmitter may encode the CSI according to the characteristics of the CSI feedback channel; and / or, when encoding the CSI to be transmitted according to the second auxiliary information, the transmitter may encode the CSI according to the requirements of the feedback CSI according to the accuracy information of the CSI feedback; and / or, when encoding the CSI to be transmitted according to the third auxiliary information, the transmitter may encode the CSI according to the background information of the transmitter and / or the receiver.

It can also sense the CSI feedback accuracy required by the wireless communication system, perform variable rate / variable code rate coding for different feedback channel states, and implement variable rate coding at the bit level / symbol level respectively to achieve the required CSI feedback accuracy, thereby improving the communication efficiency of the wireless communication system.

[0056] Step 23: The sender sends the third information.

[0057] In this embodiment, the third information is determined based on the second information. That is, after obtaining the second information, the transmitting end may process the second information, such as modulating the second information, to obtain the third information and send it.

[0058] In the information transmission method of the embodiment of the present application, the transmitting end can obtain the first information, the first information includes the CSI to be sent and the coding auxiliary information, the coding auxiliary information includes at least one of the first auxiliary information, the second auxiliary information and the third auxiliary information, the first auxiliary information is the channel-related information, the second auxiliary information is the CSI feedback accuracy information, and the third auxiliary information is the background information of the transmitting end and / or the receiving end; the CSI to be sent is coded according to the coding auxiliary information, and the CSI to be sent is coded according to the coding auxiliary information to obtain the second information, and the third information is sent, and the third information is determined based on the second information. Therefore, when encoding the CSI to be sent according to the coding auxiliary information, both the characteristics of the source and the characteristics of the channel can be considered, so as to realize the joint source-channel coding of the CSI, so as to achieve better coding performance than compressed sensing, improve the accuracy of CSI feedback, and improve the communication efficiency of the wireless communication system.

The number of coded bits used for modulation can be understood as the number of coded bits corresponding to the third information obtained by modulation. For example, if the second information is 10 and the corresponding number of bits is 2, then the number of coded bits used for modulation is 2, and 11, 01, etc. can be selected for modulation. In this way, by virtue of the fact that the number of bits of the second information is the same as the number of coded bits used for modulation, operations such as scrambling, reordering, and interleaving can be performed on the bit information obtained by encoding.

[0076] 2) The second information is bit information, and the content of the second information is the same as the content of the coded bit used for modulation. The content of the coded bit used for modulation can be understood as the content of the coded bit corresponding to the third information obtained by modulation. For example, if the second information is 10, that is, the content of the second information is 10, then the content of the coded bit used for modulation is 10.

[0077] 3) The second information is bit information, and the number of bits of the second information after the first operation is the same as the number of coded bits used for modulation. The number of coded bits used for modulation can be understood as the number of coded bits corresponding to the third information obtained by modulation. For example, the second information is 10 after the first operation, and the corresponding number of bits is 2, then the number of coded bits used for modulation is 2, and at this time, 11, 01, etc. can be selected for modulation.

[0078] 4) The second information is bit information, and the content of the second information after the first operation is the same as the content of the coded bit used for modulation. The content of the coded bit used for modulation can be understood as the content of the coded bit corresponding to the third information obtained by modulation. For example, the second information is 10 after the first operation, that is, the content of the second information after the first operation is 10, and the content of the coded bit used for modulation is 10.

[0079] 5) The second information is modulation symbol information, and the number of symbols of the second information is the same as the number of symbols of the symbol information used to map to the OFDM subcarrier.

[0081] 7) The second information is modulation symbol information, and the number of symbols of the second information after the second operation is the same as the number of symbols of the symbol information used to map to the OFDM subcarrier. The number of symbols of the symbol information used to map to the OFDM subcarrier can be understood as the number of symbols of the symbol information corresponding to the third information obtained by mapping to the OFDM subcarrier.

[0088] 3) Encoding the CSI to be transmitted at a fixed rate or fixed bit rate according to the coding auxiliary information;

[0089] 4) The CSI to be transmitted is encoded with a variable rate or variable bit rate according to the coding auxiliary information.

[0090] In this way, with the help of fixed bit rate / variable bit rate and fixed rate / variable rate coding methods, variable length coding information can be obtained, so that when performing CSI feedback, the CSI feedback overhead can be effectively reduced and the flexibility of CSI feedback is increased.

[0091] In some embodiments, at least one of the above-mentioned code rate, symbol rate, rate and bit rate can be notified by the transmitting end to the receiving end, that is, the encoder end notifies the decoder end. For example, at least one of the above-mentioned code rate, symbol rate, rate and bit rate can be notified by the transmitting end to the receiving end alone, or can be notified by the transmitting end to the receiving end together with the coding auxiliary information.

[0092] In some embodiments, at least one of the above-mentioned code rate, symbol rate, rate and bit rate can be: one of multiple pre-selected values ​​or default values. In this case, the receiving end can perform decoding attempts for multiple pre-selected values ​​or default values, and the one that is successfully decoded is the correct value.

In this case, the receiving end may perform decoding attempts for the plurality of preselected values ​​or default values, and the one successfully decoded is the correct value.

[0096] In some embodiments, the above-mentioned number of output symbols and / or number of output bits may be determined based on at least one of a predetermined target code rate, a target symbol rate, a target rate, and a target bit rate, and the first information. For example, if the predetermined target code rate or target symbol rate is a, and the information volume size / number of bits / content length of the first information is b, then the corresponding number of output symbols / number of output bits is a*b.

[0097] In some embodiments, the above-mentioned number of output symbols and / or number of output bits are related to the coding auxiliary information. For example, if the signal to noise ratio (SNR) in the coding auxiliary information is higher than a certain threshold, the number of output symbols and / or the number of output bits is N1; and if the SNR in the coding auxiliary information is lower than a certain threshold, the number of output symbols and / or the number of output bits is N2; optionally, N1>N2. For another example, if it is in a non-line of sight (NLOS) environment, the number of output symbols and / or the number of output bits is N3; and if it is in a line of sight (LOS) environment, the number of output symbols and / or the number of output bits is N4; optionally, N3>N4. Among them, N1, N2, N3 and N4 can be selected based on actual conditions, and this embodiment does not specifically limit them.

[0098] Since the CSI in the massive MIMO system can be regarded as a high-dimensional, low-rank image, the deep joint source channel coding technology for the image source has good coding performance. Therefore, the embodiment of the present application can design a coding module based on a deep neural network, and use a pre-designed coding module to perform joint source channel coding on different types of CSI, and output different coding features according to different uplink channel states to achieve better coding performance.

[0099] Optionally, the above-mentioned process of encoding the CSI to be sent according to the coding auxiliary information may include: first, the transmitting end inputs the first information into the coding module; then, the transmitting end uses the coding module to extract features of the CSI to be sent, and adjusts the extracted feature information according to the coding auxiliary information to obtain the second information. The feature extraction here can be understood as using the coding module to extract the abstract features of the CSI to be sent, and the abstract features can be decoded to obtain the estimated information of the CSI to be sent. For example, taking the coding auxiliary information including the first auxiliary information, the second auxiliary information and the third auxiliary information as an example, when the transmitting end adjusts the extracted feature information according to the coding auxiliary information, it can adjust the extracted feature information according to the characteristics of the CSI feedback channel and the background information of the transmitting end and / or the receiving end, and according to the requirements of the feedback CSI for the accuracy information of the CSI feedback, such as adjusting the length of the information output by the coding module, thereby effectively improving the bandwidth utilization.
