[0131] In some embodiments, the access network device can be composed of a centralized unit (CU) and a distributed unit (DU), where the CU can also be called a control unit. The CU-DU structure can be used to split the protocol layer of the access network device, with the functions of some protocol layers centrally controlled by the CU, and the functions of the remaining part or all of the protocol layers distributed in the DU, which is centrally controlled by the CU, but is not limited to this.

[0132] In some embodiments, the core network device can be a device including one or more network elements, or it can be multiple devices or device groups, each including all or part of one or more network elements. The network element can be virtual or physical. The core network includes, for example, at least one of the Evolved Packet Core (EPC), the 5G Core Network (5GCN), and the Next Generation Core (NGC).

[0134] The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG. 1 a , or a partial body thereof, but are not limited thereto.

[0135] The entities shown in Figure 1a are examples. The communication system may include all or part of the entities in Figure 1a, or may include other entities outside Figure 1a. The number and form of the entities are arbitrary. The connection relationship between the entities is an example.

Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0137] In the disclosed embodiments, SF compression does not provide sufficient improvement in compression performance, such as a throughput improvement of <10%. Compression performance can be improved by incorporating time domain information into the compression, such as compression based on spatial, frequency, and time domain information, i.e., SFT compression. Optionally, unlike the SF compression model, the input to the SFT compression model at each inference stage includes the measured CSI obtained from the RS measurement at the current moment and the accumulated CSI information of the previous time domain unit.

[0138] In the embodiment of the present disclosure, as shown in FIG1B , an SFT compression model, such as a CSI processing model, may include an encoding portion (Encoder) deployed on the terminal 101 side and a decoding portion (Decoder) deployed on the network device 102 side. Taking the encoding portion of terminal 101 as an example, terminal 101 may encode and quantize (Quantizer) input information (e.g., denoted as V1) based on the CSI processing model to achieve CSI compression, and may transmit the compressed information to network device 102. Network device 102 dequantizes (De-quantizer) and decodes the received information to obtain decompressed information. Cumulative CSI information is generated on both the terminal 101 side and the network device 102 side.

[0139] Optionally, the CSI processing model may include a long short-term memory (LSTM) module and a sequence model (Transformer, TF) module to process the input information.

[0140] Optionally, the accumulated CSI information may include historical CSI information (or historical information) learned in a specific scenario. If the scenario changes, the learned historical information may become unavailable, that is, the input of the CSI processing model may become unavailable. It is necessary to solve how the terminal 101 applies the CSI processing model in this case.

[0141] FIG2 is an interactive diagram of a communication processing method according to an embodiment of the present disclosure. As shown in FIG2 , an embodiment of the present disclosure relates to a communication processing method, the method comprising:

[0142] In step S2101 , the network device 102 sends configuration information to the terminal 101 .

[0143] In some embodiments, the configuration information may include CSI reporting configuration information configured for terminal 101. Optionally, the CSI reporting configuration information includes information or parameters related to CSI reporting, such as time-frequency information, periodicity, or time domain characteristics that must be met when terminal 101 reports CSI. The time domain characteristics may be semi-static or periodic.

[0144] Optionally, the CSI reporting configuration information includes: CSI resource configuration information (CSI resource configuration), and / or AI-based model configuration information (CSI-AI-model configuration).

[0145] Optionally, the CSI resource configuration information includes CSI resource information or parameters related to the CSI reporting process, such as time-frequency information or periodicity of a RS related to CSI measurement; the RS may be a Channel State Information Reference Signal (CSI-RS). The CSI reporting configuration information and the CSI resource configuration information have a mapping or associated relationship.

[0146] Optionally, the AI-based model configuration information includes model information used for CSI reporting, wherein the CSI resource configuration information and the AI-based model configuration information have a mapping or corresponding relationship.

[0147] Optionally, the configuration information includes a CSI reporting configuration identifier (CSI report configuration ID) and a corresponding CSI resource identifier (CSI resource ID). The CSI reporting configuration identifier may be CSI report configuration#1, and the CSI resource identifier may refer to a CSI resource configuration information identifier, for example, the CSI resource identifier may be CSI resource configuration#1, and the AI-based model configuration information may be CSI-AI-model#1.

[0148] Optionally, the same model configuration may correspond to different CSI resource configurations based on different configuration information of the network device 102. For example, CSI resource configuration #1 and the corresponding CSI-AI-model #1 are configured in CSI report configuration #1, and CSI resource configuration #2 and the corresponding CSI-AI-model #1 are configured in CSI report configuration #2.

[0149] In some embodiments, terminal 101 receives configuration information.

[0150] Step S2102 , the network device 102 sends activation or deactivation signaling to the terminal 101 .

[0151] In some embodiments, the activation signaling is used to activate any one or more CSI reporting configuration information, and the deactivation signaling is used to deactivate one or more CSI reporting configuration information.

[0152] Optionally, the activation signaling or deactivation signaling may be sent via a Media Access Control Control Element (MAC CE).

[0153] In one example, the network device 102 is configured with two sets of CSI reporting configuration information, respectively recorded as CSI report configuration #1 and CSI report configuration #2. The network device 102 can activate one of them through a MAC CE, or activate the two CSI reporting configuration information through MAC CEs at different times.

[0154] In this example, at other times, the network device 102 may also deactivate any CSI reporting configuration information through a MAC CE. After deactivating the CSI reporting configuration information, the CSI resource identifier corresponding to the model will change.

[0155] In some embodiments, the terminal 101 receives activation signaling, activates corresponding CSI reporting configuration information according to the activation signaling, and applies corresponding AI models and CSI resources according to the CSI reporting configuration information.

[0156] In one example, in conjunction with the preceding embodiments, network device 102 activates CSI reporting configuration #1 via MAC CE at time t1. Terminal 101 then reports CSI according to CSI resource configuration #1 and the corresponding CSI-AI-model #1. Network device 102 deactivates CSI reporting configuration #1 via MAC CE at time t2, and activates CSI reporting configuration #2 via MAC CE at time t3. Terminal 101 then reports CSI according to CSI resource configuration #2 and the corresponding CSI-AI-model #1.

[0157] Step S2103: activating the CSI processing model when the conditions are met.

[0158] Optionally, activating the CSI processing model may be initial activation or reactivation. For example, the CSI processing model has not changed, but if a condition is met, the terminal 101 may reactivate the CSI processing model in order to apply the same model again.

[0159] Optionally, when conditions are met, terminal 101 and network device 102 may simultaneously activate the CSI processing model. The predefined conditions (or rules or practices) are known to both terminal 101 and network device 102. When terminal 101 reactivates the model on the encoding side, the network device also reactivates the model on the decoding side.

[0160] In some embodiments, the condition is used to indicate a change in information associated with an input CSI of a CSI processing model, where the input CSI is obtained by the terminal 101 based on downlink RS measurement.

[0161] Optionally, the CSI processing model may be an AI or ML-based SFT model, wherein the input CSI of the model includes the measured CSI at the current moment and the accumulated CSI information before the current moment. Information associated with the input CSI includes, but is not limited to, configuration information or RS related to obtaining the two CSIs.

[0162] Optionally, the accumulated CSI information is determined based on historical CSI obtained from multiple measurements. For example, before the current moment, terminal 101 measured CSI-RS at multiple moments and obtained the measured CSI corresponding to each CSI-RS, which are recorded as multiple historical CSIs. The accumulated CSI information can be calculated and determined based on the multiple historical CSIs.

[0163] In some embodiments, activating the CSI processing model includes:

[0164] The accumulated CSI information in the CSI processing model is reset to a default value or an initial value; or, the accumulated CSI information is reset based on the terminal capability or terminal implementation.

[0165] Optionally, the default value may be 0, and the initial value may be a predefined or specific value. Optionally, the reset value may be different depending on the terminal capabilities.

[0166] In some embodiments, the condition includes at least one of the following:

[0167] Changes in the CSI reporting configuration flag corresponding to the CSI processing model;

[0168] The CSI resource identifier corresponding to the CSI processing model changes. The CSI resource identifier corresponds to the CSI reporting configuration identifier.

[0169] Changes in downlink RS information corresponding to the input CSI of the CSI processing model;

[0170] The duration during which the CSI processing model is not used exceeds the running duration of the timer.

[0171] Optionally, in the above conditions, at least one of the CSI reporting configuration identifier, the CSI resource identifier, the downlink RS information, or the duration of not using the CSI processing model is information associated with the input CSI. With reference to the description of the preceding embodiment, the input CSI of the CSI processing model includes: the measured CSI at the current moment and the accumulated CSI information before the current moment.

[0172] Among them, the measured CSI at the current moment is obtained by the terminal 101 based on the downlink RS received at the current moment, such as CSI-RS measurement, that is, the measured CSI is associated with the downlink RS information; in addition, the CSI resource identifier is used to indicate the downlink RS information related to this measurement, so that the measured CSI is associated with the CSI resource identifier; the CSI resource identifier corresponds to the CSI reporting configuration identifier of this CSI report, so that the measured CSI is associated with the CSI reporting configuration identifier.

[0173] The accumulated CSI information is related to historical CSI measured multiple times before the current moment. With reference to the method for obtaining the measured CSI, the accumulated CSI information is associated with at least one of the downlink RS information, the CSI resource identifier, or the CSI reporting configuration. Furthermore, if the duration of non-use of the CSI processing model exceeds the timer's operating duration, the accumulated CSI information temporarily stored in the CSI processing model will become invalid or inaccurate. Therefore, the accumulated CSI information is associated with whether the CSI processing model is continuously used. If the duration of non-use of the CSI processing model exceeds the operating duration, the accumulated CSI information may not be applicable.

[0174] Optionally, the downlink RS information includes:

[0175] Downlink RS characteristic information;

[0176] Downlink RS status;

[0177] The characteristic information includes at least one of time domain characteristic information, frequency domain characteristic information and space domain characteristic information, and the state includes an activated state or a deactivated state.

[0178] Optionally, when characteristic information or status of the downlink RS changes, it is considered that the condition is met.

[0179] Optionally, the time domain characteristic information includes a period of a downlink RS;

[0180] The frequency domain characteristic information includes the frequency domain unit where the downlink RS is located;

[0181] The spatial characteristic information includes the RS identifier of the downlink RS that is quasi co-located (QCL).

[0182] The downlink RS may refer to the CSI-RS, and the frequency domain unit may be the sub-band or bandwidth part (BWP) where the CSI-RS is located. That is, if the frequency domain unit where the CSI-RS is located changes, it is considered that the condition is met.

[0183] Among them, the RS identifier of the downlink RSQCL can be the CSI-RS identifier of the QCL type D (type D) of the CSI-RS or the synchronization reference signal (SS) identifier, that is, if the CSI-RS identifier or SS identifier of the QCL type D of the CSI-RS changes, it is considered that the condition is met.

[0184] Optionally, the timer is defined by a protocol or configured by a network device. For example, the running time of the timer is defined by a protocol.

[0185] In step S2104, the terminal 101 reports CSI based on the activated CSI processing model.

[0186] In some embodiments, when the conditions are met, the terminal 101 will reset the accumulated CSI information, then obtain the compressed CSI according to the CSI processing model, and report the CSI according to the activated CSI reporting configuration information.

[0187] For example, in combination with CSI report configuration #1 and CSI report configuration #2 described in the preceding embodiments, if the network device 102 deactivates CSI report configuration #1 and subsequently activates CSI report configuration #2, the terminal 101 determines that the CSI resource identifier has changed and the conditions are met, resets the accumulated CSI information of the previous time unit temporarily stored in CSI-AI-model #1 to the default value, then measures the input CSI (or measured CSI) based on the CSI-RS in CSI resource configuration #2, compresses the measured CSI using the model, and reports the CSI according to CSI report configuration #2.

[0188] In some embodiments, after the network device 102 receives the information reported by the terminal 101, it can refer to Figure 1b and the description of related embodiments to process and restore the received information.

[0287] The method disclosed herein can solve the problem of reusing a model when the UE model remains unchanged but the historical information changes. To facilitate understanding of the embodiments of the present disclosure, some specific examples are listed below:

[0288] Example 1:

[0289] The UE reactivates the AI ​​CSI sft compression model according to predefined rules or events.

[0290] Example 2:

[0291] Reactivating the AI ​​CSI sft compression model at least includes resetting the accumulated CSI information of the previous time unit temporarily stored in the model.

[0292] Example 3:

[0293] The reset behavior can be to reset to all 0s, or to reset to a specific initial value.

[0294] Example 4:

[0295] The reset behavior may depend on the UE implementation.

[0296] Example 5:

[0297] The predefined rules or events include at least:

[0298] The associated CSI resource ID of the CSI report configuration ID currently used in this model has changed;

[0299] The CSI report configuration ID used by this model has changed;

[0300] The CSI-RS characteristics corresponding to the CSI as input to the model change, including time domain characteristics such as period; frequency domain characteristics such as the frequency domain unit (sub-band, BWP) where the CSI-RS is located; and spatial domain characteristics such as the CSI-RS ID or SS-ID corresponding to the QCL type D of the CSI-RS.

[0301] The CSI-RS corresponding to the CSI as input to the model is activated or deactivated;

[0302] According to the timer configured or predefined by the base station, the model has not been used for a period exceeding the length of the timer.

[0303] Optionally, the commonality of the above is that the CSI characteristics as input change, and the CSI as input is obtained by the UE through measurement of the CSI-RS configured by the base station.

[0304] Example 6:

[0305] The predefined rules or events are known to both the UE and the gNB. When the UE performs model reactivation on the encoder side, the base station also performs model reactivation on the decoder side.

[0306] Example 7:

[0307] The method of this example may include the following steps: Step 1 to Step 3:

[0308] Step 1. The base station configures CSI report configuration #1 for the UE, which includes CSI resource configuration and CSI-AI-model configuration. The CSI resource configuration is used to indicate the measurement resource information used for the CSI reporting, such as CSI-RS information. Assuming CSI resource configuration #1, the CSI report configuration #1 is semi-statically reported. The CSI-AI-model configuration indicates the AI ​​model information used for the CSI report, such as CSI-AI-model #1. The base station configures CSI report configuration #2 for the UE, which includes CSI resource configuration #2 and CSI-AI-model #1. CSI report configuration #2 is semi-statically reported.

[0309] Step 2: The base station uses MAC CE to activate CSI reporting configuration #1 in slot #X. The UE uses CSI-AI-model #1 to perform CSI compression and reports CSI based on the compression result. After a period of time, the base station uses MAC CE to deactivate CSI reporting configuration #1 in slot #Y.

[0310] Step 3: The base station activates CSI report configuration #2 using MAC CE in slot #Z. The UE first resets the accumulated CSI information of the previous time unit temporarily stored in the CSI-AI-model #1 model to the default value, and then uses the model to compress and report the CSI measured based on the RS in CSI resource configuration #2.

[0311] Example 8:

[0312] The method of this example may include the following steps: Step 1 to Step 3:

[0313] Step 1. The base station configures CSI report configuration #1 for the UE, which includes CSI resource configuration and CSI-AI-model configuration. The CSI resource configuration is used to indicate the measurement resource information used for the CSI report, such as CSI-RS information. Assuming CSI resource configuration #1, the CSI report configuration #1 is semi-statically reported. The CSI-AI-model configuration indicates the AI ​​model information used for the CSI report, such as CSI-AI-model #1.

[0314] The base station configures timer T1 = 200ms for the UE. In one example, the timer is for CSI-AI-model #1. In another example, the timer is universal and applicable to both CSI-AI-model #1 and other models.

[0315] Step 2. The base station uses MAC CE to activate CSI reporting configuration #1 in slot #X. The UE uses CSI-AI-model #1 to perform CSI compression and reports CSI based on the compression result. After a period of time, the base station uses MAC CE to deactivate CSI reporting configuration #1 in slot #Y.

[0316] Step 3. After the deactivation signaling sent by the base station in slot #Y takes effect, the UE stops using CSI-AI-model #1. The UE starts T1 and does not use CSI-AI-model #1 until T1 expires. The UE resets the accumulated CSI info of the previous time unit temporarily stored in CSI-AI-model #1 to the default value.

[0317] The embodiments of the present disclosure further provide an apparatus for implementing any of the above methods. For example, an apparatus is provided, comprising units or modules for implementing each step performed by a terminal in any of the above methods. For another example, another apparatus is provided, comprising units or modules for implementing each step performed by a network device (e.g., an access network device, a core network function node, a core network device, etc.) in any of the above methods.

In actual implementation, they may be fully or partially integrated into a physical entity, or they may be physically separated. In addition, the units or modules in the device may be implemented in the form of a processor calling software: for example, the device includes a processor, the processor is connected to a memory, and the memory stores instructions. The processor calls the instructions stored in the memory to implement any of the above methods or implement the functions of the various units or modules of the above device, wherein the processor is, for example, a general-purpose processor, such as a central processing unit (CPU) or a microprocessor, and the memory is a memory within the device or a memory outside the device. Alternatively, the units or modules in the device can be implemented in the form of hardware circuits, and the functions of some or all of the units or modules can be realized by designing the hardware circuits.

For example, the processor is a hardware circuit implemented by an application-specific integrated circuit (ASIC) or a programmable logic device (PLD), such as an FPGA. In a reconfigurable hardware circuit, the process of the processor loading a configuration document and implementing the hardware circuit configuration can be understood as the process of the processor loading instructions to implement the functions of some or all of the above units or modules. In addition, it can also be a hardware circuit designed for artificial intelligence, which can be understood as an ASIC, such as a neural network processing unit (NPU), a tensor processing unit (TPU), a deep learning processing unit (DPU), etc.
