[0002] This application claims priority to Chinese Patent Application No. 202411883705.2, filed on December 19, 2024, entitled "Wireless Communication Method, Terminal and Network Side Device", the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application belongs to the field of communication technology, specifically relating to a wireless communication method, terminal, and network-side equipment. Background Technology

[0004] In 5G (5G) New Radio (NR) communication systems, a separate source-channel coding approach can be used for channel coding. Specifically, at the transmitting end, source coding is first used to compress data to reduce redundancy; for example, a codebook-based coding method can be used to encode the source. Then, channel coding is used to increase redundancy to combat transmission errors caused by channel fluctuations during transmission; for example, NR systems use Polar codes for channel coding.

[0005] However, when encoding the first information using a separate source channel coding method, network-side equipment typically needs to assume a maximum information volume to determine the transmission resources for the first information. During actual transmission, the terminal determines the actual amount of information to be transmitted. However, when the actual amount of information transmitted is less than the assumed maximum information volume, even if the transmission resources for the first information are plentiful, the remaining resources can only be used to increase the redundancy of channel coding, reducing resource utilization.

[0071] To facilitate a better understanding of the embodiments of this application, the related technologies are described.

[0072] (1) Channel State Information (CSI) in New Radio (NR).

[0073] In an NR system, CSI information may include at least one of the following: CSI-RS Resource Indicator (CRI), SS / PBCH Block Resource Indicator (SSBRI), Layer Indicator (LI), Rank Indication (RI), Layer 1 Reference Signal Received Power (L1-RSRP), Layer 1 Signal to Interference plus Noise Ratio (L1-SINR), and Time-Domain Channel Probing (TDCP).

[0074] Regarding CRI and SSBRI: These are resource indication identifiers. For this type of information, during CSI feedback, events identified by CRI or SSBRI are typically considered to be of equal probability and cannot be further compressed, thus requiring no source coding of resource indication identifiers.

[0075] RI: Indicates the number of transport layers supported by the UE. RI is less than or equal to the number of UE antenna ports. The UE calculates RI based on channel measurements indicated by CRI. RI has low overhead; for example, 2 bits of information can identify 1 to 4 transport layers.

[0076] LI: Indicates the column of the PMI corresponding to the strongest signal in the report; the UE calculates LI based on the Channel Quantity Indicator (CQI), PMI, RI and CRI; LI has low overhead, such as a 4-bit bitmap that can identify any of the four strongest transport layers.

[0077] L1-RSRP source coding: When the higher-layer parameter nrofReportedRS is configured to 1, the value of L1-RSRP is quantized into a 7-bit value with a step size of 1dB in the range [-140, 44]dBm. When the higher-layer parameter nrofReportedRS is configured to be greater than 1 or the higher-layer parameter groupBasedBeamReporting is enabled, the maximum value in L1-RSRP is quantized into a 7-bit value with a step size of 1dB in the range [-140, 44]dBm, and the remaining L1-RSRP values ​​are differentially quantized with the maximum L1-RSRP into 4-bit values ​​with a step size of 2dB.

[0078] L1-SINR is used for source coding: When the higher-layer parameter nrofReportedRS is configured to 1, the L1-SINR value is quantized into a 7-bit value with a step size of 0.5dB in the range [-23, 40]dB. When the higher-layer parameter nrofReportedRS is configured to be greater than 1 or the higher-layer parameter groupBasedBeamReporting is enabled, the maximum value in L1-SINR is quantized into a 7-bit value with a step size of 0.5dB in the range [-23, 40]dB, and the remaining L1-SINR values ​​are differentially quantized with the maximum L1-SINR into 4-bit values ​​with a step size of 1dB.

[0079] TDCP performs source coding: The higher-layer parameter `reportQuantity` is configured to 'tdcp' and `Y` is greater than or equal to 1, indicating that Y time-domain delays are configured; the amplitude value of each delay is represented by 4 bits. If the higher-layer parameter `phase` is configured, the phase of each delay is represented as... c i∈{0,1,…,15}, represented by 4 bits.

[0080] CQI coding: CQI is calculated based on PMI, RI, and CRI.

[0081] Broadband CQI: Uses 4 bits of information to identify the broadband CQI index.

[0082] Subband CQI: If the higher-layer parameter cqi-BitsPerSubband is not configured, 2 bits are used to identify the interpolation of subband CQI and wideband CQI; if the higher-layer parameter cqi-BitsPerSubband is configured, 4 bits are used to identify the subband CQI index.

[0083] PMI coding: Channel estimation is performed on CRI measurement resources, and the estimated channel H is decomposed into SVD: H = UΣV H Codebook-based encoding is performed on some or all vectors in the V matrix (determined by RI and CRI). The codebook types for CSI feedback are: Type I, Type II, Enhanced Type II, and Further Enhanced Type II. The feedback amount and feedback precision of the four CSI feedback codebooks increase from small to large.

[0084] (2) Separate source channel coding.

[0085] The terminal (UE) splices and aggregates some or all of the encoded CSI according to the reporting instructions configured on the network (NW). Based on the uplink channel quality sent by the NW, it adds a Cyclic Redundancy Check (CRC) to the encoded CSI and performs channel coding, modulation, and mapping to transmit symbols. The NW performs corresponding demapping, demodulation, channel decoding, CSI information partitioning, and source decoding, performs CRC checks, and obtains the original CSI.

[0086] In NR, CSI can be reported on both PUCCH and PUSCH.

[0087] To address the issue of ambiguous feedback overhead, NR employs two methods: zero-padding without splitting CSI and zero-padding with split CSI. For zero-padding with split CSI, the CSI needs to be split into two parts. The overhead of the first part is fixed, and the overhead of the second part can be determined based on the parameters of the first part.

[0088] Regarding the determination of Etot: Etot is the uplink transmission resource allocated by the NW to the UE. Typically, the NW calculates the maximum uplink transmission resource it may occupy and uses it as Etot. If the allocated Etot exceeds the actual transmission resource required, the coding rate of CSI is reduced through channel coding rate allocation to improve the robustness of CSI transmission.

[0089] (3) Joint source-channel coding method.

[0090] In 5G NR communication systems, a separate source-channel coding approach is used for channel coding. Specifically, at the transmitting end, source coding is first used to compress data to reduce redundancy; for example, a codebook-based coding method is used to encode the PMI. Then, channel coding is used to increase redundancy to combat transmission errors caused by channel fluctuations during transmission; for example, the NR system uses Polar codes for channel coding.

[0091] Compared to separate source-channel coding, joint source-channel coding considers both source and channel characteristics during transmission, optimizing the entire coding process through joint design to ensure optimal data transmission under given channel conditions. However, traditional joint source-channel coding designs face numerous challenges, including complex joint optimization problems and diverse source-channel matching issues. Through end-to-end learning, AI technology can directly learn the optimal joint source-channel coding scheme from specific sources and channels, reducing the design complexity and enabling its application in wireless communication systems.

[0092] Compared to separate source channel coding, joint source channel coding achieves higher overall transmission efficiency, with its performance advantages being more significant under low signal-to-noise ratio and low bandwidth conditions. Furthermore, separate source channel coding faces a "cliff effect" when the actual transmission channel conditions mismatch with the coding design conditions: when the actual transmission channel conditions deteriorate slightly, channel decoding may fail to effectively correct errors, leading to decoding failure and a sharp decline in transmission performance. Joint source channel coding, on the other hand, better utilizes the redundancy of the source and the characteristics of the channel, improving the overall system robustness and mitigating the "cliff effect": transmission performance gradually declines as channel quality deteriorates.

[0093] (4) Artificial Intelligence (AI) / Machine Learning (ML).

[0094] AI has been widely applied in various fields. Integrating artificial intelligence into wireless communication networks to significantly improve technical indicators such as throughput, latency, and user capacity is an important task for future wireless communication networks. AI modules can be implemented in various ways, such as neural networks, decision trees, support vector machines, and Bayesian classifiers. This application uses neural networks as an example for illustration, but it does not limit the specific type of AI module.

[0095] Figure 2 is an example of a neural network structure provided according to an embodiment of this application.

[0096] As shown in Figure 2, X1~X n Let Y be the input value and Y be the output. Each circle represents a neuron, the place where calculations are performed. The results of these calculations are then passed to the next layer. These numerous neurons forming the input layer, hidden layer, and output layer constitute a neural network. The number of hidden layers and the number of neurons in each layer define the "network structure" of the neural network. It should be understood that this application uses a neural network as an example for illustration, but it does not limit the specific type of AI module.

[0097] Figure 3 is an example of the structure of a neuron provided according to an embodiment of this application.

[0098] As shown in Figure 3, the neural network consists of neurons. The output of a neuron is z, where z = a1w1 + ... + a k w k +…+a K w K +b. Where a1~a K For input, w1~w K σ is the weight (multiplicative coefficient), b is the bias (additive coefficient), σ(.) is the activation function, and z is the output value. Activation functions include the sigmoid function, tanh function, rectified linear unit (ReLU) (also known as the linear rectified function), etc. The parameters of each neuron, combined with the algorithm used, constitute the "parameter information" of the entire network, which is a very important part of the AI ​​model file.

[0099] In practical use, an AI model refers to a file containing elements such as network structure and parameter information. The trained AI model can be directly reused by its framework platform without repeated construction or learning, and can directly perform intelligent functions such as judgment and recognition.

[0100] As can be seen from the above, when the uplink channel quality is poor, encoding CSI based on the separated source channel coding method requires the network-side equipment to allocate a large amount of uplink resources to ensure error-free transmission of CSI.

[0101] However, with the increasing requirements for transmission rates in 6-Generation (6G) mobile communication technology, the number of antenna ports will further increase, and the amount of CSI feedback will further increase, thus increasing the CSI feedback overhead.

[0102] Furthermore, when NR CSI feedback employs a separate source channel coding method, the NW typically needs to assume the maximum CSI feedback amount to determine the feedback resources. During actual transmission, the UE determines the actual feedback amount by decomposing the real channel. However, since the NR CSI feedback resources are predetermined by the NW and UE according to the protocol, when the actual CSI feedback amount is less than the NW's assumed CSI feedback amount, even if the NW allocates ample feedback resources, the remaining resources can only be used to increase the redundancy of channel coding, reducing resource utilization. Moreover, to avoid over-allocating feedback resources, NR actively discards feature vectors from some subbands for high-precision CSI reporting to reduce the overhead of CSI feedback resources, but this reduces the CSI feedback accuracy.

[0103] In this embodiment, for CSI information with constant size (such as CRI, RI, and the CQI corresponding to the first codeword), a separate source-channel coding method is used with fixed resource allocation. For CSI information with variable size (such as the CQI corresponding to the second codeword), a separate source-channel coding method is used with variable resource allocation based on the downlink channel conditions of the terminal. For CSI information that can use joint source-channel coding (such as the feature vectors of each sub-band), proportional resource allocation is performed. Because a variable resource allocation method is adopted, on the one hand, accurate CQI feedback can be ensured; on the other hand, when the actual feedback amount of CSI is less than the maximum feedback amount, the remaining resources can be fully utilized to improve the feedback quality of the feature vectors of the sub-bands. This not only ensures that the feature vectors of each sub-band can be fed back, but also reduces the problem of no usable sub-band information during feature vector recovery due to the active discarding of feature vectors from some sub-bands.

[0104] It should be noted that compared with separate source channel coding, joint source channel coding has better performance and can overcome the "cliff effect" commonly found in separate source channel coding, fully utilizing the transmission performance of the instantaneous channel. However, since the output of joint source channel coding is either channel-coded bits (bit-level joint source channel coding) or modulation symbols (symbol-level joint source channel coding), while CSI in 5G NR is considered as bit information before channel coding, the two cannot be effectively combined to improve the feedback efficiency of CSI. In this application, based on separate source channel coding, joint source channel coding is used for information in the CSI information that can be coded using joint source channel coding (e.g., feature vectors of each subband) to improve resource utilization.

This application does not specifically limit this.

[0108] Figure 4 is a schematic flowchart of a wireless communication method 200 according to an embodiment of this application.

[0109] As shown in Figure 4, the wireless communication method 200 may include at least some of the following:

[0110] S201, the terminal receives the first downlink information from the network-side equipment.

[0111] The first downlink information is used to indicate the terminal's first resource.

[0112] S201, the terminal sends the first information to the network-side device on the first resource.

[0113] The first resource includes the first part of the resource, the second part of the resource, and the third part of the resource.

[0114] The first part of the resource is used to transmit the first part of the information using the first encoding method in the first information. The size of the first part of the resource is determined according to at least one of the following: the size of the first part of the information, and the information configured by the network-side device.

[0115] The second part of the resource is used to transmit the second part of the information using the second encoding method in the first information. The size of the second part of the resource is determined according to at least one of the following: the size of the second part of the information, the information in the first part of the information used to indicate the size of the second part of the resource, and the information configured by the network-side device.

[0116] The third part of the resource is used to transmit the third part of the information using the third encoding method in the first information. The size of the third part of the resource is determined according to at least one of the following: the size of the first resource, the size of the first part of the resource, the size of the second part of the resource, the information in the first part of the information used to indicate the size of the third part of the resource, the information in the second part of the information used to indicate the size of the third part of the resource, and the information configured by the network side device.

[0117] For example, when the size of the first part of the resource, the size of the second part of the resource, or the size of the third part of the resource is determined according to the information configured by the network-side device, the network-side device may determine at least one of the following based on the channel conditions of the uplink channel of the terminal: the size of the first part of the resource, the size of the second part of the resource, or the size of the third part of the resource.

[0118] The network-side configuration information involved in this application includes, but is not limited to: Radio Resource Control (RRC) signaling, Downlink Control Information (DCI), and Media Access Control (MAC) control element (CE).

[0119] For example, when the first part of the information includes information for indicating the size of the second part of the resource, the size of the second part of the resource can be determined based on the information in the first part of the information for indicating the size of the second part of the resource.

[0120] For example, when the first part of the information includes information indicating the size of the third part of the resource, the size of the third part of the resource is determined based on the information indicating the size of the third part of the resource in the first part of the information. When the second part of the information includes information indicating the size of the third part of the resource, the size of the third part of the resource is determined based on the information indicating the size of the third part of the resource in the second part of the information.

[0121] For example, a terminal can obtain the channel conditions of its downlink channel by measuring the downlink reference signal.

[0122] For example, the first information may include downlink channel information of the terminal, such as CSI.

[0123] For example, the size of the resource involved in this application may be the number of resource units.

[0124] The resource units involved in this application include time-domain resource units, frequency-domain resource units, or time-frequency-domain resource units. A time-domain resource unit includes at least one of the following: one or more Orthogonal Frequency Division Multiplexing (OFDM) symbols, one or more time slots, one or more subframes, one or more frames, etc. A frequency-domain resource unit includes at least one of the following: one or more subbands, one or more subband groups, one or more physical resource blocks (PRBs), one or more bandwidth parts (BWPs), one or more bandwidths, one or more frequency bands, one or more carriers, or one or more subcarriers. A time-domain resource unit and a frequency-domain resource unit can form a time-frequency-domain resource unit, which can include at least one of the following: a resource element (RE), a resource block (RB), a resource element group (REG), or a resource block group (RBG).

[0125] For example, the encoding method involved in this application refers to a method for converting source information into a signal form suitable for transmission on a specific channel during information transmission, including a separate source channel coding method and a joint source channel coding method. At least some of the encoding methods in the first, second, and third encoding methods are the same or different. For example, the first and second encoding methods are separate source channel coding methods, and the third encoding method is a joint source channel coding method. In other words, after the network-side device allocates first resources to the terminal, the terminal divides the first resources into three parts: a first part of resources (Part1), a second part of resources (Part2), and a third part of resources (Part3). The first part of resources is used to transmit the first part of the information using the first encoding method (e.g., separate source channel coding method), the second part of resources is used to transmit the second part of the information using the second encoding method (e.g., separate source channel coding method), and the third part of resources is used to transmit the third part of the information using the third encoding method (e.g., joint source channel coding method).

[0126] For example, the size of the information involved in this application can be used to characterize the amount of information. For example, it can be the number of bits or other units of measurement.

[0127] In this embodiment, the size of the first part of the resource is fixed, while the sizes of the second part and the third part of the resource are variable. This helps the terminal adjust the size of the second part and the third part of the resource based on the actual amount of information transmitted, thereby improving the resource utilization rate of the first information.

[0128] In some embodiments, the resource units or ports associated with the first part of the resources are agreed upon through a protocol or configured through network-side devices, or

[0129] The resource units or ports associated with the second part are determined by protocol agreement or configured through network-side devices, or

[0130] The resource units or ports associated with the third part are determined by protocol agreements or configured through network-side devices.

[0131] For example, the port involved in this application may be an antenna port.

[0132] In this embodiment, when configuring resource units or ports associated with each part of the resources through network-side devices, distinguishing the resource units or ports associated with each part of the resources helps the network-side devices flexibly adjust resource locations, thus improving the flexibility of resource scheduling. By agreeing on the resource units or ports associated with each part of the resources through a protocol, the signaling overhead of resource scheduling can be reduced.

[0133] In some embodiments, the resource units associated with the third part of the resources are different from or adjacent to the resource units associated with the first part of the resources; or

[0134] The resource units associated in Part Three are different from or adjacent to the resource units associated in Part Two; or

[0135] The resource units associated in the second part are different from or adjacent to the resource units associated in the first part; or

[0136] The ports associated with the third part of the resources are different from or adjacent to the ports associated with the first part of the resources; or

[0137] The port associated with the third part of the resource is different from or adjacent to the port associated with the second part of the resource; or

[0138] The ports associated with the second part of the resources are different from or adjacent to the ports associated with the first part of the resources.

[0139] In this embodiment, the resource units or ports associated with each part of the resource are different or adjacent, which can reduce the probability of collisions when sending different resource units or ports associated with each part of the resource, thereby improving the transmission performance of the first information.

[0140] In some embodiments, the size of the first resource is determined based on at least one of the following:

[0141] The size of the first part of information, the maximum size of the second part of information, the first code rate for channel coding, the second code rate for channel coding, the first bias factor of the code rate, the second bias factor of the code rate, the first modulation order of the code rate, the second modulation order of the code rate, the first modulation scheme, the second modulation scheme, the maximum number of layers that the terminal can support, and the size of the resources required for each layer.

[0142] The first modulation scheme is associated with the first modulation order of the code rate, and the second modulation scheme is associated with the second modulation order of the code rate.

[0143] For example, the first modulation scheme or the second modulation scheme includes a modulation and coding scheme (MCS).

[0144] For example, the first code rate and the second code rate can be the same or different. The first bias factor and the second bias factor can be the same or different. The first modulation order and the second modulation order can be the same or different. The first modulation scheme and the second modulation scheme can be the same or different. The first code rate or the second code rate can be the maximum channel-coded transmission code rate.

[0145] For example, at least one of a first code rate, a first bias factor, a first modulation order, and a first modulation scheme is used to determine the size of the first portion of the resource. At least one of a second code rate, a second bias factor, a second modulation order, and a second modulation scheme is used to determine the size of the second portion of the resource.

[0146] For example, when determining the size of the first resource, a first bias factor and / or a second bias factor may or may not be used.

[0147] For example, the size of the resources required for each layer can be understood as: the size of the resources required by the terminal for each layer when the number of layers supported by the terminal is the maximum number of layers that the terminal can support. When the downlink channel of the terminal is at full rank, the number of layers supported by the terminal is the maximum number of layers that the terminal can support.

[0148] For example, after determining the size of the first resource, the network-side device sends first downlink information to the terminal to indicate the first resource.

[0149] In this embodiment, determining the size of the first resource based on the maximum value of the size of the second part of the information ensures that the first resource includes sufficient resources to transmit the second part of the information, thereby improving the transmission reliability of the second part of the information. Similarly, determining the size of the first resource based on the maximum number of layers the terminal can support or the size of the resources required for each layer ensures that the first resource includes sufficient resources to transmit the third part of the information, thereby improving the transmission reliability of the third part of the information.

[0150] In some embodiments, the size of the first resource is equal to the sum of the following values:

[0151] First value, second value, third value;

[0152] Wherein, the first value is equal to the size of the first part of information divided by the first product, or the first value is equal to the value obtained by dividing the size of the first part of information by the first product and then rounding it down; wherein, the first product is equal to the product of the first code rate and the first modulation order, or the first product is equal to the product of the first code rate, the first modulation order, and the first bias factor.

[0153] The second value is equal to the maximum value of the size of the second part of the information divided by the second product, or the second value is equal to the value obtained by dividing the maximum value of the size of the second part of the information by the second product and then rounding it down; wherein, the second product is equal to the product of the second code rate and the second modulation order, or the second product is equal to the product of the second code rate, the second modulation order, and the second bias factor.

[0154] The third value is determined based on the maximum number of layers that the terminal can support and the size of the resources required for each layer.

[0155] For example, the resource sizes required by different layers supported by the terminal may be the same or different. When the resource sizes required by different layers supported by the terminal may be the same, the third value is equal to the product of the maximum number of layers that the terminal can support and the resource size required by each layer.

[0156] For example, the size of the first resource is determined based on the following formula:

[0157] In this embodiment, when determining the size of the first resource based on the maximum size of the second part of the information, the maximum number of layers that the terminal can support, or the size of the resources required for each layer, it can be ensured that the first resource includes sufficient resources to transmit the second part of the information and the third part of the information, thereby improving the transmission reliability of the second part of the information and the third part of the information.

[0158] In some embodiments, the size of the first portion of the resource is determined based on the size of the first portion of the information and at least one of the following:

[0159] The first code rate, the first offset factor of the code rate, the first modulation order of the code rate, and the first modulation scheme are used for channel coding.

[0160] The first modulation scheme is associated with the first modulation order of the code rate.

[0161] For example, when determining the size of the first portion of the resource, a first bias factor may or may not be used.

[0162] In this embodiment, the information required to determine the size of the first part of the resource is clarified, which helps to improve the efficiency of determining the first part of the resource.

[0163] In some embodiments, the size of the first part of the resource is equal to the size of the first part of the information divided by the first product, or the size of the first part of the resource is equal to the value obtained by rounding down the size of the first part of the information divided by the first product.

[0164] Wherein, the first product is equal to the product of the first code rate and the first modulation order, or the first product is equal to the product of the first code rate, the first modulation order, and the first bias factor.

[0165] In this embodiment, the method for determining the size of the first part of the resource is clarified, which helps to improve the efficiency of determining the first part of the resource.

[0166] In some embodiments, the size of the second part of the resource is determined based on the size of the second part of the information and at least one of the following:

[0167] The second code rate, the second offset factor of the code rate, the second modulation order of the code rate, and the second modulation scheme are used for channel coding.

[0168] The second modulation scheme is associated with the second modulation order of the code rate.

[0169] For example, when determining the size of the second part of the resource, a second bias factor may or may not be used.

[0170] In this embodiment, the size of the second part of the resource is determined by combining the size of the second part of the information and the coding and modulation related information. This ensures that the size of the second part of the resource is a reasonable size that matches the actual amount of information transmitted and the coding and modulation related information, thereby improving the resource utilization rate of the first information.

[0171] In some embodiments, the size of the second part of the resource is equal to the size of the second part of the information divided by the second product, or the size of the second part of the resource is equal to the value obtained by dividing the maximum size of the second part of the information by the second product and then rounding it down.

[0172] The second product is equal to the product of the second code rate and the second modulation order, or the second product is equal to the product of the second code rate, the second modulation order, and the second bias factor.

[0173] In this embodiment, the size of the second part of the resource is determined by combining the size of the second part of the information and the coding and modulation related information. This ensures that the size of the second part of the resource is a reasonable size that matches the actual amount of information transmitted and the coding and modulation related information, thereby improving the resource utilization rate of the first information.

[0174] In some embodiments, the size of the third part of the resource is equal to the size of the first resource minus the sum of the sizes of the first part of the resource and the second part of the resource.

[0175] In this embodiment, the size of the third part of the resource is equal to the size of the first resource minus the sum of the sizes of the first part of the resource and the second part of the resource. This ensures that the third part of the resource includes all the remaining resources, guaranteeing that the third part of the resource has sufficient resources to transmit the third part of the information, which helps to improve the accuracy of the third part of the information.

[0176] In some embodiments, the size of the resources occupied by each feature information in the third part of the resource is determined based on the following information: the size of the third part of the resource and a first rule, wherein the first rule is a rule for dividing the third part of the resource.

[0177] For example, the first rule is determined based on at least one of the following: information agreed upon in the protocol, information configured on the network side device.

[0178] For example, the feature information in the third part of the information can be feature information of each layer supported by the terminal.

[0179] In this embodiment, by differentiating the resource sizes of each feature information in the third part of the information, each feature information in the third part of the information can be transmitted, thereby ensuring the reliability of the transmission of the third part of the information.

[0180] In some embodiments, the first rule includes one of the following:

[0181] Based on the number of feature information in the third part of the information, the third part of the resources is divided equally.

[0182] Based on the number of feature information in the third part of the information, the third part of the resources is divided into non-equal parts.

[0183] Based on the number of feature information in the third part of the information, after equally dividing the third part of the resources, the remaining resources are allocated to some feature information in the third part of the information.

[0184] In this embodiment, when the third part of the resources is divided equally, each feature information in the third part of the information can obtain sufficient transmission resources, thereby ensuring the transmission reliability of the third part of the information; when the third part of the resources is not divided equally, it helps the terminal to flexibly transmit the feature information in the third part of the information; after the third part of the resources is divided equally, when the remaining resources are allocated to some feature information in the third part of the information, the remaining resources can be utilized as much as possible, thereby improving the resource utilization rate.

[0185] In some embodiments, the size of the first portion of information is determined based on at least one of the following: information agreed upon in the protocol, information configured by the network-side device; or

[0186] The size of the second part of the information is determined based on the channel conditions of the terminal's downlink channel; or

[0187] The size of the third part of the information is determined based on the channel conditions of the terminal's downlink channel.

[0188] In this embodiment, the size of the first part of the information is determined based on at least one of the following: information agreed upon by the protocol, information configured by the network-side device, that is, the size of the first part of the information is fixed. The second part of the information and the third part of the information are affected by the channel conditions of the downlink channel of the terminal, that is, the size of the second part of the information and the size of the third part of the information are variable. In other words, by enriching the amount of information in the second part of the information and the third part of the information, the accuracy of the second part of the information and the third part of the information can be improved.

[0189] In some embodiments, the size of the second part of the information or the number of feature information in the third part of the information is determined based on the first part of the information.

[0190] For example, the size of the second part of the information and the number of feature information in the third part of the information are both determined based on the first part of the information.

[0191] In this embodiment, the size of the second part of the information or the number of feature information in the third part of the information is determined based on the first part of the information, which can ensure that the size of the second part of the information and the number of feature information in the third part of the information are variable, which helps to improve the resource utilization rate of the first resource by enriching the second part of the information and the third part of the information.

[0192] In some embodiments, the size of the Channel Quality Indicator (CQI) in the second part of the information is determined based on the Rank Indicator (RI) in the first part of the information; or

[0193] The number of feature information in the third part of the information is determined based on the rank indicator RI in the first part of the information.

[0194] For example, the first part of the information includes the CQI corresponding to the first codeword. The second part of the information may or may not include the CQI corresponding to the second codeword. For example, if RI > 4, the CQI corresponding to the second codeword needs to be fed back; if RI <= 4, the CQI corresponding to the second codeword does not need to be fed back.

[0195] For example, the number of feature information in the third part of the information is equal to the number of RI in the first part of the information.

[0196] In this embodiment, the size of the Channel Quality Indicator (CQI) in the second part of the information is determined according to the Rank Indicator (RI) in the first part of the information, or the number of feature information in the third part of the information is determined according to the Rank Indicator (RI) in the first part of the information. This ensures that the size of the second part of the information and the number of feature information in the third part of the information are variable, which helps to improve the resource utilization of the first resource by enriching the second part of the information and the third part of the information.

[0197] In some embodiments, prior to S201, method 200 further includes:

[0198] The terminal reports the second information to the network-side device;

[0199] The second piece of information is used to indicate the encoding-related information of the artificial intelligence (AI) unit.

[0200] For example, the second information is used to instruct the AI ​​unit on the relevant information used during encoding.

[0201] It should be noted that if the AI ​​unit is configured to the terminal by the network-side device based on the terminal's capabilities, the terminal does not need to report the second information to the network-side device.

[0202] In this embodiment, by reporting the second information, it is helpful or possible to assist the network-side device in selecting a suitable AI unit for corresponding decoding, thereby improving the decoding performance of the network-side device.

[0203] In some embodiments, the second information includes at least one of the following:

[0204] Each layer supports artificial intelligence (AI) units;

[0205] The number of resource units occupied by the output of each supported AI unit.

[0206] For example, the AI ​​units supported at each layer can be understood as: the number of AI units supported by the terminal at each time, assuming the terminal supports the maximum number of layers it can support. When the terminal's downlink channel is at full rank, the number of layers supported by the terminal is the maximum number of layers it can support.

[0207] For example, the number of resource units occupied by the output of each supported AI unit can be 1 or a value greater than 1. Each supported AI unit may include multiple AI units. In this case, for each layer, the second information includes multiple quantities corresponding to multiple AI units, that is, the second information includes: the number of resource units occupied by the output of each AI.

[0208] For example, the second information includes at least one of the following: identification information of the AI ​​units supported by each layer, and information indicating the number of resource units occupied by the output of the AI ​​units supported by each layer.

[0209] In this embodiment, by refining the second information, it can be ensured that the second information carries sufficient information, which helps or assists the network-side device in selecting the appropriate AI unit for corresponding decoding, thereby improving the decoding performance of the network-side device.

[0210] In some embodiments, the first downlink information includes at least one of the following:

[0211] Location indication of the first resource;

[0212] The third part of the information indicates the proportion of resources occupied by each feature in the third part of the resources.

[0213] Information about the uplink channel estimated by network-side devices.

[0214] For example, the location indication of the first resource includes the location indication of the resource unit in the first resource.

[0215] For example, the indication of resource ratios may include the ratios of various feature information or an index including resource ratios.

[0216] For example, the uplink channel information estimated by the network-side device includes, but is not limited to, signal-to-noise ratio (SNR) or SNR-related information.

[0217] In this embodiment, the first downlink information includes an indication of the resource ratio, which helps to improve the allocation message of the first resource.

[0228] Layer 1 interference-to-noise ratio (L1-SINR);

[0229] Capability Index;

[0230] Time-domain channel characteristics (TDCP);

[0231] The third part of the information indicates the proportion of resources occupied by each feature in the third part of the resources.

[0232] The third part of the information indicates the number of resource units occupied by each feature in the third part of the resources.

[0233] For example, the CQI in the first part of the information or the second part of the information can be a broadband CQI or a subband CQI.

[0234] For example, the first part of the information includes the CQI corresponding to the first codeword. The second part of the information includes the CQI corresponding to the second codeword. For instance, if RI > 4, the CQI corresponding to the second codeword needs to be fed back; if RI <= 4, the CQI corresponding to the second codeword does not need to be fed back.

[0235] In this embodiment, by enriching the types of information included in the first or second part of the information, the terminal can transmit multiple types of information simultaneously on the first or second part of the resource, thereby improving information transmission efficiency. Furthermore, when the second part of the information includes the aforementioned information, since the size of the second part of the resource is variable, the information accuracy can be improved by enriching the amount of information in each of the various types of information.

[0236] In some embodiments, the third part of the information includes at least one of the following:

[0237] CSI's bare channel;

[0238] The eigenvectors or partial eigenvectors of the V matrix obtained after SVD decomposition of the raw channel of CSI.

[0239] The information obtained from the raw channel of CSI after the first processing;

[0240] The information obtained after the second processing is the eigenvector or partial eigenvector of the V matrix obtained by the raw channel of CSI after SVD decomposition.

[0241] Channel Quality Indicator (CQI);

[0242] Partial Channel Quality Indicator (CQI).

[0243] In this embodiment, by enriching the types of information included in the third part of the information, the terminal can transmit multiple types of information at once on the third part of the resource, thereby improving information transmission efficiency. Furthermore, when the third part of the information includes the aforementioned information, since the size of the third part of the resource is variable, the information accuracy can be improved by enriching the amount of information in each of the various types of information.

[0244] In some embodiments, the first process includes at least one of the following: a process of transforming the spatial frequency domain channel information to the angular time delay domain channel, a truncation process; or the second process includes transform coding.

[0245] For example, the third part of the information may include: information obtained by transforming the spatial frequency domain channel information to the angle delay domain channel information of the CSI raw channel. Or the third part of the information may include: information obtained by truncating the CSI raw channel. Or the third part of the information may include: information obtained by transforming and encoding the eigenvectors or partial eigenvectors in the V matrix obtained after SVD decomposition of the CSI raw channel.

[0246] In this embodiment, by refining the first and second processes, the flexibility of information transmitted by the terminal on the third part of the resources can be improved.

[0247] In some embodiments, the first or second coding method is a coding method that performs source coding, channel coding, and modulation.

[0248] For example, the encoding methods of source coding include, but are not limited to, at least one of the following:

[0249] Huffman coding, arithmetic coding, LZ coding, quantization coding, differential coding, codebook-based coding, Cyclic Redundancy Check (CRC) coding, and AI model-based source coding.

[0263] In this embodiment, the first or second coding method is a coding method that performs source coding, channel coding, and modulation, which can ensure that information that only supports independent source coding and channel coding can be transmitted normally, that is, it can ensure the reliability of data transmission.

[0264] In some embodiments, the third encoding method satisfies at least one of the following:

[0265] The third encoding method is an encoding method that maps source information to signals on the channel;

[0266] The third encoding method is an encoding method that uses artificial intelligence (AI) units for encoding;

[0267] In the third part of the information, different feature information may use the same or different bit rates;

[0268] In the third part of the information, different feature information uses the same or different artificial intelligence (AI) units;

[0269] The input information for the AI ​​unit used in the third encoding method includes uplink channel information indicated by the network-side device;

[0270] The third encoding method uses an artificial intelligence (AI) unit that determines the uplink channel information indicated by the network-side equipment.

[0271] For example, when the third encoding method is an encoding method that uses an AI unit for encoding, the encoding end of the AI ​​unit is placed in the terminal, and the decoding end of the AI ​​unit is placed in the network-side device.

[0272] For example, the information of the uplink channel includes, but is not limited to, signal-to-noise ratio (SNR) or SNR-related information.

[0273] For example, the third coding method is a joint source-channel coding method.

[0274] In this embodiment, when the third coding method is a joint source-channel coding method, the resource utilization rate of the third part of the resources can be improved.

[0275] The solution of this application will be described below with reference to specific embodiments.

[0276] Example 1:

[0277] In this embodiment, after the network-side device allocates the first resource to the UE, the UE divides the first resource into three parts: a first part of the resource (Part1), a second part of the resource (Part2), and a third part of the resource (Part3). The first part of the resource is used to transmit the first part of the information using a first encoding method, the second part of the resource is used to transmit the second part of the information using a second encoding method, and the third part of the resource is used to transmit the third part of the information using a third encoding method.

[0278] The first and second coding methods are separate source-channel coding methods, while the third coding method is a joint source-channel coding method. For the third part of the first resource, the third part is divided equally based on the number of feature information elements within it.

[0279] Assuming the UE has 8 ports and the gNB has 32 ports, the UE feeds back the first information, which includes CRI, RI, LI, subband CQI, and feature vectors for each layer, with each L layer corresponding to a codeword (assuming L=4). CRI and RI belong to the first part of the information, LI and subband CQI belong to the second part, and the feature vectors for each layer belong to the third part. It should be noted that any information that the UE and NW can determine the bit size of the signal source based on pre-configured signaling before transmission can be used as the first part of the information. For example, the first part of the information may include at least one of the following: HARQ-ACK, SR, SSBRI, L1-RSRP, L1-SINR, capability index, TDCP, etc.

[0280] In some embodiments, before the UE feeds back the first information, it may also report a second information, which is used to indicate the model used by the joint source channel coding scheme supported by the UE, wherein the number in parentheses is the number of symbols after joint source channel coding:

[0281] The model IDs supported by the feature vectors of layer 1 include: 1001 (10 symbols), 1002 (15 symbols), ..., 1010 (55 symbols).

[0282] The model IDs supported by the feature vectors of layer 2 include: 2001 (10 symbols), 2002 (15 symbols), ..., 2010 (55 symbols).

[0283] The model IDs supported by the feature vectors of layer 3 include: 3001 (10 symbols), 3002 (15 symbols), ..., 3010 (55 symbols).

[0284] The model IDs supported by the feature vectors of layer 4 include: 4001 (10 symbols), 4002 (15 symbols), ..., 4010 (55 symbols).

[0285] The model IDs supported by the feature vectors of layer 5 include: 5001 (10 symbols), 5002 (15 symbols), ..., 5010 (55 symbols).

[0286] The model IDs supported by the feature vectors of layer 6 include: 6001 (10 symbols), 6002 (15 symbols), ..., 6010 (55 symbols).

[0287] The model IDs supported by the feature vectors of layer 7 include: 7001 (10 symbols), 7002 (15 symbols), ..., 7010 (55 symbols).

[0288] The model IDs supported by the feature vectors of layer 8 include: 8001 (10 symbols), 8002 (15 symbols), ..., 8010 (55 symbols).

[0289] In some embodiments, the gNB calculates the maximum uplink resources (e.g., the first resources mentioned above) that may be used based on at least one of a first code rate, a second code rate, and uplink channel conditions configured for the UE. The calculation of the first resources is illustrated below.

[0290] When are the most uplink resources needed? When the channel is at full rank, for 8 layers, the first 4 layers transmit one codeword and the last 4 layers transmit one codeword, that is, a maximum of two codewords corresponding to 8 layers can be transmitted.

[0291] The first code rate and the second code rate can be the same or different, and the first modulation order and the second modulation order can be the same or different.

[0292] For example, R_UCI_size = 200.

[0293] In some embodiments, the UE receives CSI-RS, calculates the downlink channel H, and determines the RI and codeword to be reported. The following explains the dimensions of the first part of the resources, the second part of the resources, the third part of the resources, and the method for determining the dimensions of the resources corresponding to the feature vectors of each layer.

[0294] 1. First part of the resources (R_part1).

[0295] For any downlink channel, the number of bits occupied by CRI and RI is determined, and the resource size corresponding to Part 1 is calculated:

[0296] For example, R_part1_size = 6.

[0297] 2. Second part of the resources (R_part2).

[0298] If RI <= 4, transmit 1 codeword, and the bits corresponding to the second part of the information are:

[0299] B_part2 = [B_LI, B_CQI_1].

[0300] If RI > 4, two codewords are transmitted, and the bits corresponding to the second part of the information are:

[0301] B_part2=[B_LI,B_CQI_1,B CQI_2].

[0302] For example, R_part2_size = 34.

[0303] 3. Resources in Part 3 (R_part3).

[0304] R_Part3_size=R_UCI_size-R_Part1_size–R_Part2_size.

[0305] 4. The size of the resource corresponding to the feature vector of each layer.

[0306] The size of the resource corresponding to the feature vector of each layer is:

[0307] In some embodiments, the UE selects the model ID based on R_layer_mean_size and performs joint source-channel coding on the feature vectors of each layer.

[0308] Example 1:

[0309] When RI = 8 Twenty resources are allocated to each of layers 1 to 8. Models with model IDs of 1003 (20 symbols), 2003 (20 symbols), ..., 8003 (20 symbols) are selected respectively. The feature vectors corresponding to layers 1 to 8 are jointly source-channel coded as R_layer1 (20 symbols), R_layer2 (20 symbols), ..., R_layer8 (20 symbols), and R_part3 = [R_layer1, R_layer2, ..., R_layer8]. The first resource is R_UCI = [R_part1, R_part2, R_part3].

[0310] Example 2:

[0311] When RI = 6 Model IDs with output symbol counts less than the maximum symbol count in R_layer1_mean_size are selected for layers 1 through 6, namely 1004 (25 symbols), 2004 (25 symbols), ..., 6004 (25 symbols). Using the above models, the feature vectors corresponding to layers 1 through 6 are jointly source-channel coded as R_layer1 (25 symbols), R_layer2 (25 symbols), ..., R_layer6 (25 symbols), and R_part3 = [R_layer1, R_layer2, ..., R_layer6, R_filling (10 symbols)]. The first resource is R_UCI = [R_part1, R_part2, R_part3].

[0312] Example 3:

[0313] When RI = 4 Forty resources are allocated to each of layers 1 to 4, using model IDs 1007 (40 symbols), 2007 (40 symbols), ..., 4007 (40 symbols) respectively. Joint source-channel coding is performed on the feature vectors corresponding to layers 1 to 4, resulting in R_layer1 (40 symbols), R_layer2 (40 symbols), ..., R_layer4 (40 symbols), and R_part3 = [R_layer1, R_layer2, ..., R_layer4]. The first resource is R_UCI = [R_part1, R_part2, R_part3].

[0314] Example 4:

[0315] When RI = 2 For layers 1 and 2, select model IDs with an output symbol count less than the maximum symbol count in R_layer1_mean_size, namely 1010 (55 symbols) and 1020 (55 symbols). Using the above models, perform joint source-channel coding on the feature vectors corresponding to layers 1 and 2, encoding them as R_layer1 (55 symbols), R_layer2 (55 symbols), and R_part2 = [R_layer1, R_layer2, R_filling (50 symbols)]. The first resource is R_UCI = [R_part1, R_part2, R_part3].

[0316] As can be seen, the above example can fully utilize the resources in Part 3 by increasing the number of output symbols corresponding to the model ID. It should be noted that if the number of output symbols corresponding to a model ID is 80, then for Example 4, R_filling does not need to be configured.

[0317] In some embodiments, after receiving R_UCI, the NW side calculates R_part1_size, decodes R_part1, and obtains RI. Based on the obtained RI, the NW calculates R_part2_size and R_part3_size to obtain R_part2. Decoding is then performed using the corresponding model for each layer based on R_part3_size.

[0318] Example 2:

[0319] In this embodiment, after the network-side device allocates the first resource to the UE, the UE divides the first resource into three parts: a first part of the resource (Part1), a second part of the resource (Part2), and a third part of the resource (Part3). The first part of the resource is used to transmit the first part of the information using a first encoding method, the second part of the resource is used to transmit the second part of the information using a second encoding method, and the third part of the resource is used to transmit the third part of the information using a third encoding method.

[0320] Among them, the first and second coding methods are separate source-channel coding methods, and the third coding method is a joint source-channel coding method. For the third part of the first resource, based on the number of feature information in the third part of the information, the third part of the resource is divided equally, and the remaining resources are allocated to some feature information in the third part of the information.

[0321] It should be noted that Embodiment 1 and Embodiment 2 are similar, except that, due to the different way of dividing the third part of the resources, the method of determining the size of the resource corresponding to the feature vector of each layer in Embodiment 2 is different from that in Embodiment 1.

[0322] For example, Example 2 of Embodiment 1 can be modified as follows:

[0323] When RI = 6 For layers 1 through 6, select model IDs whose output symbol count is less than the maximum symbol count in R_layer1_mean_size, i.e., 1005 (25 symbols), 2005 (25 symbols), ..., 6005 (25 symbols). Then calculate the remaining resource count: R_filling = 160 - 25 * 6 = 10 symbols. Next, evenly distribute the remaining resources to layers 1 and 2, updating the model ID used by layer 1 to 1006 (30 symbols) and the model ID used by layer 2 to 2006 (30 symbols). Using models 1005, 2005, 3004, ..., 6004, the feature vectors corresponding to layers 1 to 6 are jointly source-channel coded as R_layer1 (30 symbols), R_layer2 (30 symbols), R_layer3 (25 symbols), R_layer4 (25 symbols), R_layer5 (25 symbols), R_layer6 (25 symbols), and R_part2 = [R_layer1, R_layer2, ..., R_layer6]. The first resource is R_UCI = [R_part1, R_part2, R_part3].

[0324] Example 3:

[0325] In this embodiment, after the network-side device allocates the first resource to the UE, the UE divides the first resource into three parts: a first part of the resource (Part1), a second part of the resource (Part2), and a third part of the resource (Part3). The first part of the resource is used to transmit the first part of the information using a first encoding method, the second part of the resource is used to transmit the second part of the information using a second encoding method, and the third part of the resource is used to transmit the third part of the information using a third encoding method.

[0326] Among them, the first and second coding methods are separate source-channel coding methods, and the third coding method is a joint source-channel coding method. For the third part of the first resource, the third part of the resource is divided into non-equal parts based on the number of feature information in the third part of the information.

[0327] Assuming the UE has 8 ports and the gNB has 32 ports, the UE feeds back the first information, which includes CRI, RI, LI, subband CQI, and feature vectors for each layer, with each L layer corresponding to a codeword (assuming L=4). CRI and RI belong to the first part of the information, LI and subband CQI belong to the second part, and the feature vectors for each layer belong to the third part. It should be noted that any information that the UE and NW can determine the bit size of the signal source based on pre-configured signaling before transmission can be used as the first part of the information. For example, the first part of the information may include at least one of the following: HARQ-ACK, SR, SSBRI, L1-RSRP, L1-SINR, capability index, TDCP, etc.

[0328] In some embodiments, before the UE feeds back the first information, it may also report a second information, which is used to indicate the model used by the joint source channel coding scheme supported by the UE, wherein the number in parentheses is the number of symbols after joint source channel coding:

[0329] The model IDs supported by the feature vectors of layer 1 include: 1001 (10 symbols), 1002 (15 symbols), ..., 1010 (55 symbols).

[0330] The model IDs supported by the feature vectors of layer 2 include: 2001 (10 symbols), 2002 (15 symbols), ..., 2010 (55 symbols).

[0331] The model IDs supported by the feature vectors of layer 3 include: 3001 (10 symbols), 3002 (15 symbols), ..., 3010 (55 symbols).

[0332] The model IDs supported by the feature vectors of layer 4 include: 4001 (10 symbols), 4002 (15 symbols), ..., 4010 (55 symbols).

[0333] The model IDs supported by the feature vectors of layer 5 include: 5001 (10 symbols), 5002 (15 symbols), ..., 5010 (55 symbols).

[0334] The model IDs supported by the feature vectors of layer 6 include: 6001 (10 symbols), 6002 (15 symbols), ..., 6010 (55 symbols).

[0335] The model IDs supported by the feature vectors of layer 7 include: 7001 (10 symbols), 7002 (15 symbols), ..., 7010 (55 symbols).

[0336] The model IDs supported by the feature vectors of layer 8 include: 8001 (10 symbols), 8002 (15 symbols), ..., 8010 (55 symbols).

[0337] The following explains the resource proportion occupied by each feature information in the third part of the information.

[0338] For example, Table 1 can be used to determine the proportion of resources occupied by each feature information in the third part of the information.

[0339] Table 1

[0340] It should be noted that Table 1 may contain proportionally allocated indexes. The contents of Table 1 can be replaced with the number of output symbols. When it is expected that the NW side will be used for indication, since the NW does not know the actual channel rank, it may configure an index for each rank, or configure an index with a rank of 8. If the rank is not full, the proportion will be scaled accordingly.

[0341] In some embodiments, the gNB calculates the maximum uplink resources (e.g., the first resources mentioned above) that may be used based on at least one of a first code rate, a second code rate, and uplink channel conditions configured for the UE. The calculation of the first resources is illustrated below.

[0342] When are the most uplink resources needed? When the channel is at full rank, for 8 layers, the first 4 layers transmit one codeword and the last 4 layers transmit one codeword, that is, a maximum of two codewords corresponding to 8 layers can be transmitted. The first code rate and the second code rate can be the same or different, and the first modulation order and the second modulation order can be the same or different.

[0343] For example, R_UCI_size = 200.

[0344] In some embodiments, the UE receives CSI-RS, calculates the downlink channel H, and determines the RI and codeword to be reported. The following explains the dimensions of the first part of the resources, the second part of the resources, the third part of the resources, and the method for determining the dimensions of the resources corresponding to the feature vectors of each layer.

[0345] 1. First part of the resources (R_part1).

[0346] For any downlink channel, the number of bits occupied by CRI, RI, LI, the CQI of the first codeword, and the number of bits for the Part3 resource ratio index are determined. The bits corresponding to the first part of the information are: B_part1 = [B_CRI, B_RI, B_LI, B_CQI_1, B_Index].

[0347] For example, R_part1_size = 40.

[0348] 2. Second part of the resources (R_part2).

[0349] When RI <= 4, R_part2_size = 0. When RI > 4,

[0350] 3. Resources in Part 3 (R_part3).

[0351] R_Part3_size=R_UCI_size-R_Part1_size–R_Part2_size.

[0352] For example, R_part3_size = 160.

[0353] 4. The size of the resource corresponding to the feature vector of each layer.

[0354] The size of the resource corresponding to the feature vector of each layer is:

[0355] Example 1:

[0356] Assuming that when RI = 8, B_index = 15, the resource ratio of each feature information in the third part of the information is shown in Table 2.

[0357] Table 2

[0358] Based on Table 2, Select a model ID for layer 1 whose output symbol count is less than the maximum symbol count in R_layer1_size, i.e., 1005 (30 symbols); Select a model ID for layer 2 whose output symbol count is less than the maximum symbol count in R_layer2_size, i.e., 2003 (20 symbols); Select a model ID for layer 3 whose number of output symbols is less than the maximum number of symbols in R_layer3_size, i.e., 3003 (20 symbols); Select a model ID for layer 4 whose number of output symbols is less than the maximum number of symbols in R_layer4_size, i.e., 4002 (15 symbols); Select a model ID for layer 5 whose number of output symbols is less than the maximum number of symbols in R_layer5_size, i.e., 5002 (15 symbols); Select a model ID for layer 6 whose number of output symbols is less than the maximum number of symbols in R_layer6_size, i.e., 6002 (15 symbols); Select a model ID for layer 7 whose number of output symbols is less than the maximum number of symbols in R_layer7_size, i.e., 7002 (15 symbols); Select a model ID for layer 8 whose number of output symbols is less than the maximum number of symbols in R_layer8_size, i.e., 8002 (15 symbols).

[0359] Using the model allocated above, the feature vectors corresponding to layers 1 to 8 are jointly source-channel coded as follows: R_layer1 (30 symbols), R_layer2 (20 symbols), R_layer3 (20 symbols), R_layer4 (15 symbols), R_layer5 (15 symbols), R_layer6 (15 symbols), R_layer7 (15 symbols), R_layer8 (15 symbols), R_part2 = [R_layer1, R_layer2, ..., R_layer8, R_fill (15 symbols)]. The first resource is R_UCI = [R_part1, R_part2 (may not exist), R_part3].

[0360] Example 2:

[0361] Example 1:

[0362] Assuming that when RI=8, B_index=7, the resource ratio of each feature information in the third part of the information is shown in Table 3.

[0363] Table 3

[0364] Based on Table 3 Select a model ID for layer 1 whose output symbol count is less than the maximum symbol count in R_layer1_size, i.e., 1010 (55 symbols); Select a model ID for layer 2 whose output symbol count is less than the maximum symbol count in R_layer2_size, i.e., 1008 (45 symbols); Select a model ID for layer 3 whose number of output symbols is less than the maximum number of symbols in R_layer3_size, i.e., 1005 (30 symbols); Select a model ID for layer 4 whose number of output symbols is less than the maximum number of symbols in R_layer4_size, i.e., 1002 (15 symbols).

[0365] Using the model allocated above, the feature vectors corresponding to layers 1 to 4 are jointly source-channel coded as R_layer1 (45 symbols), R_layer2 (45 symbols), R_layer3 (30 symbols), and R_layer4 (30 symbols), with R_part2 = [R_layer1, R_layer2, R_layer3, R_layer4, R_fill (15 symbols)]. The first resource is R_UCI = [R_part1, R_part2 (possibly none), R_part3].

[0366] As can be seen, the above example can make full use of the resources in Part 3 by increasing the number of output symbols corresponding to the model ID.

[0367] In some embodiments, after receiving R_UCI, the NW side calculates R_part1_size, decodes R_part1, and obtains RI. Based on the obtained RI, the NW calculates R_part2_size and R_part3_size to obtain R_part2. Decoding is performed using the corresponding model for each layer based on R_part3_size and the proportion of each layer.

[0378] In some embodiments, the resource units or ports associated with the first part of the resources are agreed upon through a protocol or configured through network-side devices, or

[0379] The resource units or ports associated with the second part are determined by protocol agreement or configured through network-side devices, or

[0380] The resource units or ports associated with the third part are determined by protocol agreements or configured through network-side devices.

[0381] In some embodiments, the resource units associated with the third part of the resources are different from or adjacent to the resource units associated with the first part of the resources; or

[0382] The resource units associated in Part Three are different from or adjacent to the resource units associated in Part Two; or

[0383] The resource units associated in the second part are different from or adjacent to the resource units associated in the first part; or

[0384] The ports associated with the third part of the resources are different from or adjacent to the ports associated with the first part of the resources; or
