[0023] Based on the same inventive concept, a second aspect of this application provides a data transmission method for an air interface, applied to a smart simplified wireless node, wherein the smart simplified wireless node is provided with a second protocol stack of a preset structure, and the method includes:

[0024] Receive a first transmission signal or a second transmission signal sent by a user terminal, and determine the type of the first transmission signal or the second transmission signal;

The obtained first decoded semantic domain data packets are then sent to a preset target node. The encoding processing of source information of semantic domain type is realized through the application layer semantic coding protocol, and the transparent transmission processing mode of the first protocol stack is used in the transmission process, so that the content of the encoded semantic domain data packets does not need to be changed when they are transmitted through the protocol stack, thereby simplifying the processing process in the protocol stack transmission process and improving the data transmission efficiency.

[0070] This embodiment proposes a data transmission method for an air interface, applied to a user terminal. The user terminal is equipped with a first protocol stack with a preset structure, such as... Figure 1 As shown, the method includes:

[0071] Step 101: Obtain the first source information, determine that the type of the first source information is a semantic domain type, and then encode the first source information according to the preset application layer semantic coding protocol to obtain the encoded semantic domain data packet.

[0072] In specific implementation, the transmission in the first protocol stack is divided into uplink and downlink scenarios. In the uplink scenario, the usage scenario of the encoding protocol is first determined, that is, whether the first source information sent by the user is of semantic domain type. If it is the first source information of semantic domain type, the ALS protocol (Application Layer Semantic-coding) is used to encode the first source information to obtain the encoded semantic domain data packet.

[0073] In this step, such as Figure 3A As shown, the structure of the first protocol stack in the UE (i.e., user terminal) is divided into SDAP (Service Data Adaptation Protocol), PDCP (Packet Data Convergence Protocol), RLC (Radio Link Control), MAC (Medium Access Control), and RFPHY (Radio Frequency Physical Layer) from top to bottom. This layered approach gives the communication protocol high cohesion and low coupling, greatly facilitating the modification of the protocol and the expansion of services.

[0074] The ALS protocol (Application Layer Semantic Coding) corresponds to semantic communication services. The internal operation of the ALS protocol is to use a semantic coding model to semantically encode source information of different modalities and output encoded semantic domain data packets. In addition, the ALS protocol enables communication systems to efficiently process semantic domain type information, giving full play to the advantages of semantic domain type information and further improving the transmission and processing efficiency of large-scale user data.

[0075] Step 102: Transmit the encoded semantic domain data packet transparently in the first protocol stack in a top-to-bottom order to obtain a first transmission signal, and send it to the intelligent simplified wireless node for decoding at the intelligent simplified wireless node. Then, send the obtained first decoded semantic domain data packet to a preset target node.

[0076] In practical implementation, transmission in the first protocol stack is divided into uplink and downlink scenarios. In the uplink scenario, encoded semantic domain data packets pass through the SDAP layer, PDCP layer, RLC layer, and MAC layer in the first protocol stack, and are finally transmitted to the RFPHY layer, ready to be sent into the channel. Among these:

[0077] If the transmitted semantic domain type encoded semantic domain data packet is transmitted, it is transmitted transparently in the SDAP layer, PDCP layer, RLC layer, and MAC layer. That is, the encoded semantic domain data packet only needs to be processed in the first protocol stack by adding and decoding the packet header information and channel mapping, while its internal data is not changed.

[0078] After passing through the above four layers, the encoded semantic domain data packet reaches the RFPHY layer, where time-frequency resource mapping is performed to obtain the first transmission signal, which is then transmitted to the iNB (i.e., the intelligent and simplified wireless node) through the wireless port I-Uu.

[0079] In this step, the output encoded semantic domain data packet is transmitted to the lower layer of the first protocol stack based on the "cross-layer protocol" design. That is, it is transparently transmitted through protocol tunnels in protocol layers such as SDAP, PDCP, RLC, and MAC, and time-frequency resource mapping is performed in the RFPHY layer to obtain the first transmission signal in the form of electrical signals.

[0080] In this context, transparent transmission of each protocol layer in the first protocol stack means that when encoded semantic domain data packets pass through the aforementioned protocol layers, the encoded semantic domain data packets only need to undergo header information addition, decoding, and channel mapping in the first protocol stack, while the internal data (i.e., the transmission content of semantic domain type source information) remains unchanged. This reduces the data processing process during transmission, thereby simplifying the processing in the protocol stack transmission and improving the efficiency of data transmission.

[0081] The above scheme obtains first source information of semantic domain type. The first source information is then encoded using a pre-defined application-layer semantic coding protocol in the first protocol stack to process semantic domain types, resulting in encoded semantic domain data packets. These encoded semantic domain data packets are then transparently transmitted in the first protocol stack from top to bottom to obtain a first transmission signal, which is sent to the intelligent simplified wireless node for decoding. The resulting first decoded semantic domain data packets are then sent to a pre-defined target node. The application-layer semantic coding protocol enables the encoding of source information of semantic domain type, and the transparent transmission processing of the first protocol stack during transmission simplifies the process by eliminating the need to modify the content of the encoded semantic domain data packets during transmission. This enables the transmission of semantic domain type information to the user terminal and improves data transmission efficiency.

[0082] In some embodiments, the first protocol stack is provided with a first uplink mapping channel of a preset structure, the first uplink mapping channel including a first uplink logical channel, a first uplink transmission channel and a first uplink physical channel.

[0083] In step 102, the transparent transmission of the encoded semantic domain data packet in the first protocol stack in a top-to-bottom order to obtain the first transmission signal includes:

[0084] Step 1021: Map the encoded semantic domain data packet from the first uplink logical channel to the first uplink transmission channel.

[0085] Step 1022: Map the encoded semantic domain data packets mapped to the first uplink transmission channel to the first uplink physical channel, and perform time-frequency resource mapping on the encoded semantic domain data packets mapped to the first uplink physical channel to obtain the first transmission signal.

[0086] In practical implementation, transmission in the first protocol stack is divided into uplink and downlink scenarios. In the uplink scenario, such as Figure 3B As shown, to more clearly describe the processing flow of the first transmission signal between the protocol layers of the first protocol stack, the first uplink mapping channel is divided into three categories according to the steps between different protocol layers: the first uplink logical channel, the first uplink transmission channel, and the first uplink physical channel. Each category of channel contains multiple different channels responsible for transmitting different types of information. The correspondence between the various types of channels, i.e., the channel mapping scheme, is as follows:

[0087] The first uplink logical channel includes, but is not limited to, existing logical channel classifications such as the Common Control Channel (CCCH), the Dedicated Control Channel (DCCH), and the Dedicated Service Channel (DTCH).

[0088] The first uplink transport channel includes the Uplink Data Sharing Channel (UL-DSCH) and the Uplink Semantic Sharing Channel (UL-SSCH). The UL-DSCH is responsible for transmitting service data belonging to the data domain type of traditional communication in the uplink, while the UL-SSCH is responsible for transmitting service data belonging to the semantic domain type of semantic communication in the uplink. Furthermore, the first uplink transport channel also includes, but is not limited to, transport channel classifications found in existing wireless communication systems such as RACH.

[0089] The first uplink physical channel includes, but is not limited to, existing physical channel classifications such as the Physical Uplink Shared Channel (PUSCH), Physical Random Access Channel (PRACH), and Physical Uplink Control Channel (PUCCH). The functions of PUCCH and PRACH are the same as those in existing wireless communication systems. The difference is that the PUSCH in this application supports the processing of semantic domain type information and time-frequency resource mapping. Furthermore, an uplink semantic control indicator (USCI) is introduced in PUCCH and PUSCH to indicate the location of the semantic channel region (i.e., the location of the first transmission signal in the first uplink physical channel).

[0090] The mapping process of the user terminal (UE) of the intelligent simplified air interface in the uplink scenario is as follows:

[0091] Mapping from the first uplink logical channel to the first uplink transport channel:

[0092] The CCCH, DCCH, and DTCH in the first uplink logical channel of the intelligent simplified air interface uplink can carry information of either the data domain type or the semantic domain type. During the channel mapping process from the first uplink logical channel to the first uplink transmission channel, the semantic domain type information in these channels will be mapped to the UL-SSCH in the first uplink transmission channel, and the data domain type information in these channels will be mapped to the UL-DSCH in the first uplink transmission channel.

[0093] Mapping from the first uplink transport channel to the first uplink physical channel:

[0094] In the first uplink transmission channel, the UL-DSCH carries data domain information, while the UL-SSCH carries semantic domain information. Information from both channels is mapped into the PUSCH during the mapping process to the first uplink physical channel. During this process, the Downlink Semantic Control Indicator (USCI) is added to both the PUCCH and PUSCH to indicate the location of the PUSCH semantic channel region.

[0095] The first uplink logical channel includes three channels: CCCH, DCCH, and DTCH. All three channels can carry both semantic domain information and data domain information. During the channel mapping process from the first uplink logical channel to the first uplink transmission channel, semantic domain information from these channels is mapped to the UL-SSCH in the first uplink transmission channel, and data domain information from these channels is mapped to the UL-DSCH in the first uplink logical channel transmission channel.

[0096] The first uplink transmission channel has four channels: UL-SSCH, UL-DSCH, and RACH. UL-SSCH carries semantic domain type information, and UL-DSCH carries data domain type information. Both are mapped to PDSCH in the first uplink physical channel.

[0097] The first uplink physical channel consists of three channels: PUSCH, PUCCH, and PRACH. USCI is introduced in PUSCH and PUCCH to indicate the location of the semantic channel region.

[0098] In the above scheme, the first uplink mapping channel can be fully compatible with the traditional data domain mapping channel for semantic channel mapping. It can support the transmission of information of semantic domain type while also supporting the transmission of information of data domain type, and the system is highly flexible.

[0099] In some embodiments, the method further includes:

[0100] Step A1: If the type of the first source information is determined to be a data field type, then the first source information is encoded according to a preset application layer data encoding protocol to obtain an encoded data field data packet.

[0101] Step A2: The encoded data field data packet is transmitted in the first protocol stack in a top-to-bottom order to obtain a second transmission signal, which is then transmitted to the intelligent simplified wireless node for decoding. The resulting decoded data field data packet is then sent to the preset target node.

[0102] In specific implementation, the transmission in the first protocol stack is divided into uplink and downlink scenarios. In the uplink scenario, the usage scenario of the encoding protocol is first determined, that is, whether the first source information sent by the user belongs to the data domain type. If it is the source information of the data domain type, the ALD protocol (Application Layer Data-coding) is used to encode the first source information to obtain the encoded data domain data packet.

[0103] The internal operation of the ALD protocol is the same as the digital encoding methods supported in existing wireless communication systems. That is, for source information of different modes, the corresponding digital source encoding algorithm is used to perform lossy or lossless source compression, and output encoded data field data packets. Subsequently, the processing of encoded data field data packets is exactly the same as the protocol stack processing process in existing wireless communication systems. That is, the processing is performed layer by layer by the SDAP layer, PDCP layer, RLC layer, and MAC layer. The encoded data field data packets are transmitted to the RFPHY layer through the SDAP layer, PDCP layer, RLC layer, and MAC layer in the protocol stack, and are finally sent to the channel.

[0104] After passing through the above four layers, the encoded data packet reaches the RFPHY layer, where time-frequency resource mapping is performed to obtain the second transmission signal in the form of an electrical signal. Finally, it is sent to the physical channel and transmitted to the iNB (i.e., the intelligent and simplified wireless node) through the wireless port I-Uu.

[0105] The source information belonging to the semantic domain type is different from the source information belonging to the data domain type:

[0106] Semantic domain source information consists of feature vectors extracted from the source in a high-dimensional space. These feature vectors represent the semantic features of the source and are extracted through a deep learning model.

[0107] The source information of the data field type is the bit sequence obtained by statistically compressing the source information, that is, the bit sequence obtained after processing by the protocol stack.

[0108] For example, in the transmission of text-based information, the semantic domain data consists of feature vectors extracted by a deep neural network model. These feature vectors represent semantic information such as sentence meaning and text structure. The data in the data domain, on the other hand, consists of probability statistics of the symbols in the text, encoded using entropy coding methods.

[0109] Furthermore, in image-based information transmission scenarios, the semantic domain data consists of feature vectors extracted using deep neural network models. These feature vectors represent information such as image structure and texture. The data in the data domain, on the other hand, consists of bit sequences obtained by compressing and encoding the image.

[0110] The above scheme achieves full compatibility for information transmission of semantic domain type and information transmission of data domain type. It can support the transmission of information of semantic domain type while also supporting the transmission of information of data domain type, and the system is highly flexible.

[0111] Furthermore, since semantic domain information itself has better noise resistance, there is no need to change the transmitted content during the transmission process (i.e., unlike the transmission of traditional data domain information, there is no need to change the transmitted content to ensure noise resistance). Therefore, a transparent transmission method is adopted to transmit semantic domain information without changing the transmitted content of the semantic domain source information, which simplifies the transmission process and improves transmission efficiency.

[0112] In some embodiments, the first protocol stack includes an application layer, and the application layer semantic encoding protocol is configured in the application layer.

[0113] The method further includes:

[0114] Step B1: Receive the third transmission signal sent by the intelligent simplified wireless node, determine that the type of the third transmission signal is a semantic domain type, and then transparently transmit the third transmission signal in the first protocol stack in a bottom-up order to the application layer.

[0115] Step B2: Decode the third transmission signal according to the application layer semantic coding protocol in the application layer to obtain the second decoded semantic domain data packet.

[0116] In practical implementation, transmission in the first protocol stack is divided into uplink and downlink scenarios. In the downlink scenario, such as Figure 3A As shown, after receiving the third transmission signal from the Smart Wireless Node (iNB), the User Terminal (UE) performs different processing according to the type of the third transmission signal.

[0117] If the third transmission signal is of the semantic domain type, the user terminal UE will process the received third transmission signal based on the "cross-layer protocol". That is, it will be transmitted transparently through the RFPHY layer, MAC layer, RLC layer, PDCP layer and SDAP layer. During this process, the header information will be added, decoded and channel mapped, and the internal data will not be changed.

[0118] If the third transmission signal is of the data domain type, the user terminal UE processes the third transmission signal in the same way as the existing wireless communication system, that is, it processes the MAC layer, RLC layer, PDCP layer and SDAP layer from bottom to top.

[0119] The third transmission signal transmitted to the user terminal (UE) undergoes processing at the RFPHY, MAC, RLC, PDCP, and SDAP layers before being delivered to the application layer for decoding. Specifically:

[0120] If the third transmission signal of the semantic domain type is decoded using the ALS protocol (i.e., the application layer semantic coding protocol), that is, the semantic coding model is used to recover and decode the source information using the received semantic data to obtain the second decoded semantic domain data packet.

[0121] If it is a third transmission signal of the data domain type, then the ALD protocol (i.e., application layer data encoding protocol) is used for decoding.

[0122] In some embodiments, the first protocol stack is provided with a first downlink mapping channel of a preset structure, the first downlink mapping channel including a first downlink logical channel, a first downlink transmission channel and a first downlink physical channel;

[0123] In step B1, the transparent transmission of the third transmission signal in the first protocol stack in a bottom-up order to the application layer includes:

[0124] Step B11: Map the third transmission signal from the first downlink physical channel to the first downlink transmission channel.

[0125] Step B12: Map the third transmission signal mapped to the first downlink transmission channel to the first downlink logical channel, and transmit the third transmission signal mapped to the first downlink logical channel to the application layer.

[0126] In practical implementation, transmission in the first protocol stack is divided into uplink and downlink scenarios. In the downlink scenario, such as Figure 3D As shown, the first downlink mapping channel of the intelligent simplified air interface is divided into three categories: the first downlink logical channel, the first downlink transport channel, and the first downlink physical channel. Among them:

[0127] The first downlink logical channels include, but are not limited to, existing logical channel classifications such as Broadcast Control Channel (BCCH), Paging Control Channel (PCCH), Common Control Channel (CCCH), Dedicated Control Channel (DCCH), and Dedicated Service Channel (DTCH).

[0128] The first downlink transport channel includes the downlink data sharing channel (DL-DSCH) and the downlink semantic sharing channel (DL-SSCH). The DL-DSCH is responsible for transmitting data domain service data in the downlink, while the DL-SSCH is responsible for transmitting semantic domain service data in the downlink. In addition, the first downlink transport channel also includes, but is not limited to, existing transport channel classifications such as the broadcast channel (BCH) and the paging channel (PCH).

[0129] The first downlink physical channel includes, but is not limited to, existing physical channel classifications such as the Physical Downlink Shared Channel (PDSCH), Physical Broadcast Channel (PBCH), and Physical Downlink Control Channel (PDCCH). The difference is that the PDSCH in this application supports the processing of semantic domain type information and time-frequency resource mapping, and also introduces a Downlink Semantic Control Indicator (DSCI) in the PDCCH in conjunction with the PDSCH to indicate the location of the semantic channel region (i.e., the location of the third transmission signal in the first downlink physical channel).

[0130] The mapping process of the user terminal (UE) of the intelligent simplified air interface in the downlink scenario is as follows:

[0131] The third transmission signal is mapped from the first downlink physical channel to the first downlink transmission channel. Then, the third transmission signal mapped to the first downlink transmission channel is mapped to the first downlink logical channel, and the third transmission signal mapped to the first downlink logical channel is transmitted to the application layer.

[0132] In the mapping process from the first downlink physical channel to the first downlink transport channel, information in the PBCH of the first downlink physical channel is mapped to the BCH of the first transport channel. Information in the PDSCH of the first downlink physical channel is mapped to the DL-DSCH, DL-SSCH, or PCH of the first downlink transport channel. Specifically, semantic field type information carried in the PDSCH is mapped to the DL-SSCH of the first transport channel, data field type information carried in the PDSCH is mapped to the DL-DSCH of the first transport channel, and paging information carried in the PDSCH is mapped to the PCH of the first downlink transport channel. During this process, DCI is extracted from the PDCCH to provide relevant control signaling. Simultaneously, DSCI is extracted from both the PDCCH and PDSCH to indicate the semantic channel region within the PDSCH.

[0133] During the mapping process from the first downlink transport channel to the first downlink logical channel, information in the PCH of the first downlink transport channel will be mapped to the PCCH of the first downlink logical channel. Information in the BCH of the first downlink transport channel will be mapped to the BCCH of the first downlink logical channel. Information on the data field type in the DL-DSCH of the first downlink transport channel will be mapped to the BCCH, CCCH, DTCH, or DCCH of the first downlink logical channel according to its specific purpose. Semantic field data in the DL-SSCH of the first downlink transport channel will also be mapped to the BCCH, CCCH, DTCH, or DCCH of the first downlink logical channel according to its specific purpose.

[0134] In the above scheme, the first downlink mapping channel can be fully compatible with the traditional data domain mapping channel for semantic channel mapping. It can support the transmission of information of semantic domain type while also supporting the transmission of information of data domain type, and the system is highly flexible.

[0135] Based on the same inventive concept, embodiments of this application also provide a data transmission method for an air interface, applied to a smart simplified wireless node, wherein the smart simplified wireless node is provided with a second protocol stack with a preset structure, such as... Figure 2 As shown, the method includes:

[0136] Step 201: Receive a first transmission signal or a second transmission signal sent by the user terminal, and determine the type of the first transmission signal or the second transmission signal.

[0137] Step 202: In response to determining that the type of the first transmission signal is a semantic domain type, the first transmission signal is transparently transmitted in the second protocol stack in a bottom-up order to obtain a first decoded semantic domain data packet, and the first decoded semantic domain data packet is sent to a preset target node.

[0138] Step 203: In response to determining that the type of the second transmission signal is a data domain type, the second transmission signal is transmitted in the second protocol stack in a bottom-up order to obtain a decoded data domain data packet, and the decoded data domain data packet is sent to the preset target node.

[0139] In practice, the transmission in the second protocol stack is divided into uplink and downlink scenarios. In the uplink scenario, the intelligent wireless node iNB performs different processing based on the type of the domain to which the signal belongs after receiving the signal from the user terminal UE.

[0140] like Figure 3A As shown, when the Smart Simplified Wireless Node (iNB) receives a first transmission signal of semantic domain type, the iNB will process the received first transmission signal based on a "cross-layer protocol." That is, it will transparently transmit the first transmission signal from the RFPHY layer to the SDAP layer, and obtain the first decoded semantic domain data packet through channel mapping, packet header parsing, and other processing procedures, completing the processing flow of the Smart Simplified Air Interface's second protocol stack. Afterward, it will be sent to the protocol stacks and core network of subsequent processing nodes, and finally to the preset target node.

[0141] When the Smart Wireless Node (iNB) receives a second transmission signal of type data domain, the iNB processes the second transmission signal in the same way as existing wireless communication systems, that is, it processes the RFPHY layer, MAC layer, RLC layer, PDCP layer, and SDAP layer from bottom to top, and then performs subsequent processing.

[0142] Finally, the iNB (Intelligent Simple Wireless Node) sends the processed first decoded semantic domain data packet or decoded data domain data packet through the user plane (UPF) to the core network, and finally to the preset target node.

[0143] In some embodiments, the second protocol stack is provided with a second uplink mapping channel of a preset structure, the second uplink mapping channel including a second uplink logical channel, a second uplink transmission channel and a second uplink physical channel;

[0144] In step 202, the transparent transmission of the first transmission signal in the second protocol stack in a bottom-up order to obtain the first decoded semantic domain data packet includes:

[0145] Step 2021: Map the first transmission signal from the second uplink physical channel to the second uplink transmission channel.

[0146] Step 2022: Map the first transmission signal mapped to the second uplink transmission channel to the second uplink logical channel, and decode the first transmission signal mapped to the second uplink logical channel to obtain the first decoded semantic domain data packet.

[0147] In practical implementation, transmission in the second protocol stack is divided into uplink and downlink scenarios. In the uplink scenario, such as Figure 3E As shown, the second uplink mapping channel of the intelligent simplified air interface is divided into three categories: the second uplink logical channel, the second uplink transmission channel, and the second uplink physical channel. Among them:

[0148] The second uplink logical channel includes, but is not limited to, existing logical channel classifications such as the Common Control Channel (CCCH), the Dedicated Control Channel (DCCH), and the Dedicated Service Channel (DTCH).

[0149] The second uplink transport channel includes the Uplink Data Sharing Channel (UL-DSCH) and the Uplink Semantic Sharing Channel (UL-SSCH). The UL-DSCH is responsible for transmitting data domain service data in the uplink, while the UL-SSCH is responsible for transmitting semantic domain service data in the uplink. In addition, transport channels also include, but are not limited to, the transport channel classifications found in existing wireless communication systems such as RACH.

[0150] The second uplink physical channel includes, but is not limited to, existing physical channel classifications such as the Physical Uplink Shared Channel (PUSCH), Physical Random Access Channel (PRACH), and Physical Uplink Control Channel (PUCCH). The functions of PUCCH and PRACH are the same as those in existing wireless communication systems. The difference is that the PUSCH in this application supports the processing of semantic domain information and time-frequency resource mapping. Furthermore, an uplink semantic control indicator (USCI) is introduced in PUCCH and PUSCH to indicate the location of the semantic channel region (i.e., the location of the first transmission signal in the second uplink physical channel).

[0151] The mapping process of the simplified wireless node iNB in ​​the uplink scenario for the simplified air interface is as follows:

[0152] Mapping from the second uplink logical channel to the second uplink transport channel:

[0153] The first transmission signal (or the second transmission signal) is mapped from the second uplink physical channel to the second uplink transmission channel. Then, the first transmission signal (or the second transmission signal) mapped to the second uplink transmission channel is mapped to the second uplink logical channel.

[0154] During the mapping process from the second uplink physical channel to the second uplink transport channel, information in the PRACH of the second uplink physical channel will be mapped to the RACH of the second uplink transport channel. Information in the PUSCH of the second uplink physical channel will be mapped to the UL-DSCH or UL-SSCH of the second uplink physical channel. Specifically, the data field information carried in the PUSCH will be mapped to the UL-DSCH, and the semantic field information carried in the PUSCH will be mapped to the UL-SSCH. Simultaneously, during this process, UCI and USCI will be extracted from the PUCCH and PUSCH of the first uplink physical channel. UCI is used to provide relevant control signaling, and USCI is used to indicate the semantic channel region within the PUSCH.

[0155] During the mapping process from the second uplink transport channel to the second uplink logical channel, the data field information in the UL-DSCH of the second uplink transport channel will be mapped to the CCCH, DTCH, or DCCH of the first uplink logical channel according to its specific purpose. Similarly, the semantic field information in the UL-SSCH of the second uplink transport channel will also be mapped to the CCCH, DTCH, or DCCH of the first uplink logical channel according to its specific purpose.

[0156] In the above scheme, the second uplink mapping channel can be fully compatible with the traditional data domain mapping channel for semantic channel mapping. It can support the transmission of information of semantic domain type while also supporting the transmission of information of data domain type, and the system is highly flexible.

[0157] In some embodiments, the method further includes:

[0158] Step C1: Receive the second source information sent by the target node, determine that the type of the second source information is a semantic domain type, then transparently transmit the second source information in the second protocol stack in a top-to-bottom order to obtain the third transmission signal, and send it to the user terminal.

[0159] In practical implementation, transmission in the second protocol stack is divided into uplink and downlink scenarios. In the downlink scenario, such as Figure 3A As shown, the second source information sent from the target node is transmitted to the Smart Simplified Radio Node (iNB) via the User Plane UPF and then transmitted in the second protocol stack of the Smart Simplified Air Interface of the iNB. During this process:

[0160] If the transmitted second source information is of semantic domain type, it is transparently transmitted in the SDAP layer, PDCP layer, RLC layer, and MAC layer. That is, the second source information only needs to be processed in the protocol stack by adding, decoding, and channel mapping of packet header information, while its internal data remains unchanged.

[0161] If the transmitted second source information is of the data domain type, the processing method after passing through the above four layers is the same as that in the existing wireless communication system, that is, processing is performed layer by layer through the SDAP layer, PDCP layer, RLC layer, and MAC layer.

[0162] After passing through the above four layers, the third transmission signal or the third transmission signal reaches the RFPHY layer, where time-frequency resource mapping is performed, it is converted into an electrical signal, and finally sent to the wireless channel and transmitted to the user terminal UE through the wireless port I-Uu.

[0163] In some embodiments, the second protocol stack is provided with a second downlink mapping channel of a preset structure, the second downlink mapping channel including a second downlink logical channel, a second downlink transmission channel and a second downlink physical channel;

[0164] In step C1, the transparent transmission of the second source information in the second protocol stack in a top-to-bottom order to obtain the third transmission signal includes:

[0165] Step C11: Map the second source information from the second downlink logical channel to the second downlink transmission channel.

[0166] Step C12: Map the second source information mapped to the second downlink transmission channel to the second downlink physical channel, and perform time-frequency resource mapping on the third transmission signal mapped to the second downlink semantic domain physical channel to obtain the third transmission signal.

[0167] In practical implementation, transmission in the second protocol stack is divided into uplink and downlink scenarios. In the downlink scenario, such as Figure 3C As shown, the second downlink mapping channel of the intelligent simplified air interface is divided into three categories: the second downlink logical channel, the second downlink transport channel, and the second downlink physical channel. Among them:

[0168] The second downlink logical channels include, but are not limited to, existing logical channel classifications such as Broadcast Control Channel (BCCH), Paging Control Channel (PCCH), Common Control Channel (CCCH), Dedicated Control Channel (DCCH), and Dedicated Service Channel (DTCH).

[0169] The second downlink transport channel includes the downlink data sharing channel (DL-DSCH) and the downlink semantic sharing channel (DL-SSCH). The DL-DSCH is responsible for transmitting data domain service data in the downlink, while the DL-SSCH is responsible for transmitting semantic domain service data in the downlink. In addition, the second downlink transport channel also includes, but is not limited to, existing transport channel classifications such as the broadcast channel (BCH) and the paging channel (PCH).

[0170] The second downlink physical channel includes, but is not limited to, existing physical channel classifications such as the Physical Downlink Shared Channel (PDSCH), Physical Broadcast Channel (PBCH), and Physical Downlink Control Channel (PDCCH). The difference is that the PDSCH in this application supports the processing of semantic domain information and time-frequency resource mapping, and also introduces a Downlink Semantic Control Indicator (DSCI) in the PDCCH in conjunction with the PDSCH, used to indicate the location of the semantic channel region (i.e., the location of the third transmission signal in the second downlink semantic domain physical channel).

[0171] The mapping process of the simplified wireless node iNB of the simplified air interface in the downlink scenario is as follows:

[0172] Mapping from the second downlink logical channel to the second downlink transport channel:

[0173] The second downlink logical channel of the intelligent simplified air interface can carry semantic domain type information through channels such as BCCH, CCCH, DTCH, and DCCH. During the channel mapping process from the second downlink logical channel to the second downlink transmission channel, the semantic domain type information in these channels will be mapped to the DL-SSCH in the second downlink transmission channel, and the data domain type information in these channels will be mapped to the DL-DSCH in the second downlink transmission channel.

[0174] Mapping of the second downlink transport channel to the second downlink physical channel:

[0175] In the second downlink transmission channel, the DL-DSCH carries data-domain information, while the DL-SSCH carries semantic-domain information. Information from both channels is mapped into the PUSCH during the mapping process to the second downlink physical channel. During this process, the DSCI is added to the PDCCH and PDSCH to indicate the location of the semantic channel region (i.e., the location of the third transmission signal in the second downlink semantic domain physical channel).

[0176] The second downlink logical channel contains five channels: PCCH, BCCH, CCCH, DTCH, and DCCH. PCCH does not carry semantic domain type information. The remaining BCCH, CCCH, DTCH, and DCCH can carry both semantic domain type information and data domain type information. During the channel mapping from the second downlink logical channel to the second downlink transport channel, the semantic domain type information from these channels is mapped to the DL-SSCH in the second downlink transport channel, and the data domain type information from these channels is mapped to the DL-DSCH in the second downlink transport channel. Furthermore, information in the BCCH is also mapped to the BCH in the second downlink transport channel.

[0177] The second downlink transport channel includes four channels: PCH, BCH, DL-SSCH, and DL-DSCH. DL-SSCH carries semantic domain type information, while DL-DSCH carries data domain type information; both are mapped to PDSCH in the second downlink physical channel.

[0178] The second downlink physical channel includes PBCH, PDSCH, and PDCCH. DSCI is introduced in PDSCH and PDCCH to indicate the location of semantic channel regions.

[0179] In the above scheme, the second downlink mapping channel can be fully compatible with the traditional data domain mapping channel for semantic channel mapping. It can support the transmission of information of semantic domain type while also supporting the transmission of information of data domain type, and the system is highly flexible.

[0180] By employing the above scheme and transparently transmitting source information of semantic domain types, source information of semantic domain types can be transmitted without altering its content. This reduces data processing during transmission and improves data transmission efficiency.

[0181] It should be noted that the method in this embodiment can be executed by a single device, such as a computer or server. The method can also be applied in a distributed scenario, where multiple devices cooperate to complete the task. In such a distributed scenario, one of these devices may execute only one or more steps of the method in this embodiment, and the multiple devices will interact with each other to complete the method described.
