The data transmission method of the air interface provided in this embodiment is applied to a user terminal, where the user terminal is provided with a first protocol stack with a preset structure, as shown in fig. 1, and the method includes:

step 101, acquiring first information source information, and determining that the type of the first information source information is a semantic domain type, and then encoding the first information source information according to a preset application layer semantic encoding protocol to obtain an encoded semantic domain data packet.

In the implementation, the transmission in the first protocol stack is divided into an uplink scene and a downlink scene, in the uplink scene, firstly, the use scene of the coding protocol is determined, namely, whether the first information source information sent by the user is of a semantic domain type is judged, and if the first information source information is of the semantic domain type, the first information source information is coded by adopting an ALS protocol (Application LayerSemantic-coding, application layer semantic coding protocol) to obtain a coded semantic domain data packet.

In this step, as shown in fig. 3A, the structure of the first protocol stack in the UE (i.e., the user terminal) is sequentially divided into SDAP (servicedataadaptation protocol, service data application layer), PDCP (packetdataconvergence protocol), RLC (RadioLink Control, radio link control layer), MAC (medium access control layer) and RFPHY (radio frequency physical layer) from top to bottom, so that the communication protocol has high cohesive and low coupling characteristics in a layered manner, thereby greatly facilitating modification of the protocol and expansion of the service.

The ALS protocol (application layer semantic coding protocol) corresponds to the service of semantic communication, the operation inside the ALS protocol is to carry out semantic coding on information source information of different modes by utilizing a semantic coding model and output a coded semantic domain data packet, and in addition, the ALS protocol can realize the capability of enabling a communication system to efficiently process information of semantic domain type, fully plays the advantages of the information of the semantic domain type and further improves the transmission processing efficiency of large-scale user data.

Step 102, the encoded semantic domain data packet is transparently transmitted in the first protocol stack according to the sequence from top to bottom, so as to obtain a first transmission signal, and the first transmission signal is sent to an intelligent wireless node end, so that the intelligent wireless node end decodes the first transmission signal, and the obtained first decoded semantic domain data packet is sent to a preset target node.

In the implementation, the transmission in the first protocol stack is divided into an uplink scene and a downlink scene, and in the uplink scene, the coding semantic domain data packet is transmitted to the RFPHY layer through the SDAP layer, the PDCP layer, the RLC layer and the MAC layer in the first protocol stack, and is ready to be sent to a channel. Wherein:

if the encoded semantic domain data packet of the semantic domain type is transmitted, transparent transmission is performed in the SDAP layer, the PDCP layer, the RLC layer and the MAC layer, namely, the encoded semantic domain data packet only needs to be subjected to the processes of adding and decoding packet header information, channel mapping and the like in the first protocol stack, and the internal data of the encoded semantic domain data packet is not changed.

After the four layers, the encoded semantic domain data packet reaches the RFPHY layer, and is subjected to time-frequency resource mapping in the RFPHY layer to obtain a first transmission signal, and the first transmission signal is transmitted to iNB (namely, intelligent wireless node end) through a wireless port I-Uu.

In the step, the output coding semantic domain data packet is designed based on a cross-layer protocol when transmitted to the lower layer of the first protocol stack, namely, transparent transmission is carried out in a protocol layer such as SDAP, PDCP, RLC, MAC through a protocol tunnel, and time-frequency resource mapping is carried out in an RFPHY layer, so that a first transmission signal in the form of an electric signal is obtained.

When the encoded semantic domain data packet passes through the protocol layers, the encoded semantic domain data packet only needs to be processed such as adding, decoding, channel mapping and the like of packet header information in the first protocol stack, and the data (i.e. the transmission content of the semantic domain type source information) in the first protocol stack is not changed, so that the data processing process in the transmission process is reduced, the processing process in the transmission of the protocol stack is simplified, and the data transmission efficiency is improved.

According to the scheme, the first information source information which is of the semantic domain type is obtained, the first information source information is encoded through an application layer semantic encoding protocol which is preset in a first protocol stack and is used for processing the semantic domain type, an encoded semantic domain data packet is obtained, then transparent transmission is carried out on the encoded semantic domain data packet in the first protocol stack according to the sequence from top to bottom, a first transmission signal is obtained, the first transmission signal is sent to an intelligent wireless node end, decoding is carried out on the first transmission signal at the intelligent wireless node end, the obtained first decoding semantic domain data packet is sent to a preset target node, encoding processing of the information source information of the semantic domain type is achieved through the application layer semantic encoding protocol, and a transparent transmission processing mode of the first protocol stack is utilized in the transmission process, so that the encoded semantic domain data packet does not need to change contents in the transmission process of the encoded semantic domain data packet through the protocol stack, the processing process in the protocol stack transmission process is simplified, the transmission process of the information supporting the semantic domain type in the user end is achieved, and the data transmission efficiency is improved.

In some embodiments, a first uplink mapping channel with a preset structure is provided in the first protocol stack, where the first uplink mapping channel includes a first uplink logical channel, a first uplink transmission channel, and a first uplink physical channel.

In step 102, the transparent transmission of the encoded semantic domain data packet in the first protocol stack according to the sequence from top to bottom, to obtain a first transmission signal, which includes:

and step 1021, mapping the encoded semantic domain data packet from the first uplink logical channel to the first uplink transmission channel.

Step 1022, mapping the encoded semantic domain data packet mapped to the first uplink transmission channel to the first uplink physical channel, and performing time-frequency resource mapping on the encoded semantic domain data packet mapped to the first uplink physical channel to obtain a first transmission signal.

In specific implementation, the transmission in the first protocol stack is divided into an uplink scene and a downlink scene, in the uplink scene, as shown in fig. 3B, in order 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 types according to links between different protocol layers: each type of channel comprises a plurality of different channels and is responsible for transmitting different types of information, and the corresponding relation among the various channels, namely the channel mapping scheme is as follows:

The first uplink logical channel includes, but is not limited to, common control channel CCCH, dedicated control channel DCCH, dedicated traffic channel DTCH, and other existing logical channel classifications.

The first uplink transmission channel comprises an uplink data sharing channel UL-DSCH and an uplink semantic sharing channel UL-SSCH, wherein the function of UL-DSCH is responsible for transmitting traffic data belonging to a data domain type of traditional communication in an uplink, and the function of UL-SSCH is responsible for transmitting traffic data belonging to a semantic domain type of semantic communication in an uplink. The first uplink transmission channel further includes, but is not limited to, a transmission channel class in an existing radio communication system such as RACH.

The first uplink physical channel includes, but is not limited to, a physical uplink shared channel PUSCH, a physical random access channel PRACH, a physical uplink control channel PUCCH, and other existing physical channel classifications, and functions of the PUCCH and the PRACH are the same as those in an existing wireless communication system, except that the PUSCH in the present application supports processing of information of a semantic domain type and mapping of time-frequency resources, and uplink semantic control indication USCI is also introduced in the PUCCH and the PUSCH, for indicating a position of a semantic channel region (i.e., a position of a first transmission signal in the first uplink physical channel).

The mapping process of the user terminal UE of the intelligent air interface in the uplink scene is as follows:

mapping of the first uplink logical channel to the first uplink transport channel:

the CCCH, DCCH, and DTCH in the first uplink logical channel of the intelligent air interface uplink may carry information of a data domain type, and may also carry information of a semantic domain type. In the course of channel mapping from the first uplink logical channel to the first uplink transport channel, the information of semantic domain types in these channels will be mapped into UL-SSCH in the first uplink transport channel, and the information of data domain types in these channels will be mapped into UL-DSCH in the first uplink transport channel.

Mapping of the first uplink transport channel to the first uplink physical channel:

information of the data domain carried in the UL-DSCH in the first uplink transport channel, and information of the semantic domain carried in the UL-SSCH. The information in the two channels is mapped to the PUSCH in the process of mapping to the first uplink physical channel, and in the process, a downlink semantic control indication pointer USCI is added to the PUCCH and the PUSCH and used for indicating the position of a PUSCH semantic channel region.

The first uplink logical channel has three channels, namely CCCH, DCCH and DTCH. All three channels can carry information of semantic domain type and information of data domain type. In the course of channel mapping from the first uplink logical channel to the first uplink transport channel, the information of semantic domain types in these channels will be mapped into UL-SSCH in the first uplink transport channel, and the information of data domain types in these channels will be mapped into UL-DSCH in the first uplink logical channel transport channel.

The first uplink transmission channel has four channels of UL-SSCH, UL-DSCH and RACH. The UL-SSCH carries information of semantic domain type and the UL-DSCH carries information of data domain type, both of which are mapped into the PDSCH in the first uplink physical channel.

In the first uplink physical channel, PUSCH, PUCCH, PRACH channels, USCI is introduced into PUSCH and PUCCH to indicate the location of the semantic channel region.

In the scheme, the first uplink mapping channel maps the semantic channel to be completely compatible with the channel mapped by the traditional data domain, so that the transmission of the information of the data domain type can be well supported while the transmission of the information of the semantic domain type is supported, and the system flexibility is high.

In some embodiments, the method further comprises:

and A1, determining that the type of the first information source information is a data domain type, and encoding the first information source information according to a preset application layer data encoding protocol to obtain an encoded data domain data packet.

And step A2, transmitting the coded data field data packet in the first protocol stack according to the sequence from top to bottom to obtain a second transmission signal, and transmitting the obtained decoded data field data packet to the preset target node by the intelligent wireless node end for decoding the second transmission signal at the intelligent wireless node end.

In the implementation, the transmission in the first protocol stack is divided into an uplink scene and a downlink scene, in the uplink scene, the use scene of the coding protocol is determined first, that is, whether the first information source information sent by the user belongs to the data domain type is judged, if the first information source information is the information source information of the data domain type, the first information source information is coded by adopting an ALD protocol (Application LayerData-coding, application layer data coding protocol) to obtain a coded data domain data packet.

The operation in the ALD protocol is the same as the digital coding mode supported in the existing wireless communication system, namely, the corresponding digital source coding algorithm is adopted to perform lossy or lossless source compression on the source information of different modes, and the coded data field data packet is output, and then, the processing procedure of the coded data field data packet is also completely the same as the processing procedure of a protocol stack in the existing wireless communication system, namely, the SDAP layer, the PDCP layer, the RLC layer and the MAC layer are processed layer by layer, and the coded data field data packet is finally transmitted to the RFPHY layer through the SDAP layer, the PDCP layer, the RLC layer and the MAC layer in the protocol stack and is ready to be transmitted to a channel.

After the four layers, the coded data field data packet reaches the RFPHY layer, and is subjected to time-frequency resource mapping in the RFPHY layer to obtain a second transmission signal in the form of an electric signal, and finally the second transmission signal is sent to a physical channel and is transmitted to iNB (namely, intelligent wireless node end) through a wireless port I-Uu.

Wherein, the source information belonging to the semantic domain type and the source information belonging to the data domain type are different:

the information source information of the semantic domain type is a feature vector in a high-dimensional space extracted from the information source, wherein the feature vector can be used for representing semantic features of the information source and is extracted through a deep learning model.

The information source information of the data domain type is a bit sequence obtained by carrying out statistical compression on the information source information, namely, a bit sequence obtained after protocol stack processing.

For example: in a transmission scene of text type information source information, data belonging to semantic domain types are feature vectors extracted through a deep neural network model, and the feature vectors represent semantic information such as sentence meaning, text structure and the like. And the data belonging to the data field type is to carry out probability statistics on symbols in the text and encode the symbols by using an entropy encoding method.

In addition, in the transmission scene of the image type information source information, the data belonging to the semantic domain type are feature vectors extracted through the deep neural network model, and the feature vectors represent the information such as image structures, textures and the like. And the data belonging to the data field type is a bit sequence obtained by compression encoding the image.

In the scheme, the complete compatibility of the semantic domain type information transmission and the data domain type information transmission is realized, the semantic domain type information transmission is supported, the data domain type information transmission is well supported, and the system flexibility is high.

In addition, the semantic domain type information has better anti-noise performance, so that the processing process of changing the transmission content is not needed in the transmission processing process (namely, the anti-noise performance can be guaranteed only by changing the transmission content as in the transmission of the traditional data domain type information), the semantic domain type information is transmitted in a transparent transmission mode, the transmission content of the semantic domain type information source information is not changed, the transmission processing process is simplified, and the transmission efficiency is improved.

In some embodiments, an application layer is provided in the first protocol stack, and the application layer semantic coding protocol is provided in the application layer.

The method further comprises the steps of:

and B1, receiving a third transmission signal sent by the intelligent wireless node, and transmitting the third transmission signal to the application layer by transparent transmission in the first protocol stack according to the sequence from bottom to top if the type of the third transmission signal is determined to be a semantic domain type.

And B2, decoding the third transmission signal according to an application layer semantic coding protocol in the application layer to obtain a second decoding semantic domain data packet.

In the implementation, the transmission in the first protocol stack is divided into an uplink scenario and a downlink scenario, in the downlink scenario, as shown in fig. 3A, after receiving a third transmission signal sent by the intelligent wireless node iNB, the UE performs corresponding different processing according to the type of the third transmission signal.

If the type of the third transmission signal is the semantic domain type, the UE processes the received third transmission signal based on the cross-layer protocol, that is, the third transmission signal passes through the RFPHY layer, the MAC layer, the RLC layer, the PDCP layer, and the SDAP layer in a transparent transmission manner, and processes such as adding and decoding packet header information and mapping channels are completed in the process, so that internal data is not changed.

If the type of the third transmission signal is the data domain type, the manner of processing the third transmission signal by the user terminal UE is the same as that of the existing wireless communication system, that is, the processing of the MAC layer, the RLC layer, the PDCP layer and the SDAP layer is performed layer by layer from bottom to top.

The third transmission signal transmitted to the UE is delivered to the application layer for decoding after being processed by the RFPHY layer, the MAC layer, the RLC layer, the PDCP layer, and the SDAP layer, where:

And if the third transmission signal of the semantic domain type is decoded by adopting an ALS protocol (namely an application layer semantic coding protocol), namely, the semantic coding model is adopted to recover and decode the information source information by utilizing the received semantic data, so as to obtain a second decoding semantic domain data packet.

In the case of a third transmission signal of the data field type, the decoding takes place using the ALD protocol (i.e. using the layer data encoding protocol).

In some embodiments, a first downlink mapping channel of a preset structure is set in the first protocol stack, where the first downlink mapping channel includes a first downlink logical channel, a first downlink transmission channel, and a first downlink physical channel;

in step B1, the transmitting the third transmission signal to the application layer in the first protocol stack in a sequence from bottom to top includes:

and step B11, mapping the third transmission signal from the first downlink physical channel to the first downlink transmission channel.

And step B12, mapping the third transmission signal mapped to the first downlink transmission channel to the first downlink logic channel, and transmitting the third transmission signal mapped to the first downlink logic channel to the application layer.

In implementation, the transmission in the first protocol stack is divided into an uplink scenario and a downlink scenario, and in the downlink scenario, as shown in fig. 3D, the first downlink mapping channels of the intelligent air interface are divided into three categories: a first downlink logical channel, a first downlink transport channel, and a first downlink physical channel. Wherein:

the first downlink logical channel includes, but is not limited to, existing logical channel classifications of broadcast control channel BCCH, paging control channel PCCH, common control channel CCCH, dedicated control channel DCCH, and dedicated traffic channel DTCH.

The first downlink transmission channel comprises a downlink data shared channel DL-DSCH and a downlink semantic shared channel DL-SSCH. The DL-DSCH is responsible for the transmission of data domain traffic data in the downlink, and the DL-SSCH is responsible for the transmission of semantic domain traffic data in the downlink. In addition, the first downlink transport channel further includes, but is not limited to, existing transport channel classifications of broadcast channel BCH, paging channel PCH, and the like.

The first downlink physical channel includes, but is not limited to, existing physical channel classifications such as a physical downlink shared channel PDSCH, a physical broadcast channel PBCH, and a physical downlink control channel PDCCH. In contrast, the PDSCH in the present application supports processing of semantic domain type information and time-frequency resource mapping, and a downlink semantic control indicator DSCI is further introduced in the PDCCH 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).

The mapping process of the user terminal UE of the intelligent air interface in the downlink scene is as follows:

the third transmission signal is mapped from the first downlink physical channel to the first downlink transmission channel. And mapping the third transmission signal mapped to the first downlink transmission channel to the first downlink logic channel, and transmitting the third transmission signal mapped to the first downlink logic channel to the application layer.

In the process of mapping the first downlink physical channel to the first downlink transport channel, information in the PBCH in the first downlink physical channel is mapped to the BCH in the first transport channel. Information in PDSCH in the first downlink physical channel will be mapped into DL-DSCH, DL-SSCH or PCH in the first downlink transport channel, wherein information of semantic domain type carried in PDSCH will be mapped into DL-SSCH in the first transport channel, when information of data domain type carried in PDSCH will be mapped into DL-DSCH in the first transport channel, and paging information carried in PDSCH will be mapped into PCH of the first downlink transport channel. In this procedure, DCI is extracted from the PDCCH for providing relevant control signaling. Meanwhile, DSCI is extracted from PDCCH and PDSCH to indicate semantic channel region inside PDSCH.

In the mapping process of the first downlink transmission channel to the first downlink logic channel, information in the PCH in the first downlink transmission channel is mapped to the PCCH in the first downlink logic channel. The information in the BCH in the first downlink transport channel will be mapped into the BCCH in the first downlink logical channel. The information of the data field type in the DL-DSCH in the first downlink transport channel will be mapped into BCCH, CCCH, DTCH or DCCH in the first downlink logical channel depending on its specific use. The semantic domain data of DL-SSCH in the first downlink transport channel is also mapped into BCCH, CCCH, DTCH or DCCH in the first downlink logical channel according to its specific use.

As shown in fig. 3A, when the intelligent wireless node iNB receives the first transmission signal of the semantic domain type, the intelligent wireless node iNB processes the received first transmission signal based on the "cross-layer protocol", that is, uses a transparent transmission manner to transmit the first transmission signal from the RFPHY layer to the SDAP layer, and obtains a first decoded semantic domain packet through processing procedures such as channel mapping and packet header parsing, so as to complete a processing procedure of the second protocol stack of the intelligent air interface. And then, sending the message to a protocol stack and a core network of a subsequent processing node, and finally sending the message to a preset target node.

When the intelligent wireless node iNB receives the second transmission signal of the data domain type, the intelligent wireless node iNB processes the second transmission signal in the same manner as the existing wireless communication system, that is, processes the RFPHY layer, the MAC layer, the RLC layer, the PDCP layer, and the SDAP layer by layer from bottom to top, and performs subsequent processing thereafter.

Finally, the intelligent wireless node iNB sends the processed first decoded semantic domain data packet or the decoded data domain data packet to the core network through a User Plane (UPF), and finally sends the first decoded semantic domain data packet or the decoded data domain data packet to a preset target node.

Wherein:

the second uplink logical channel includes, but is not limited to, common control channel CCCH, dedicated control channel DCCH, dedicated traffic channel DTCH, and other existing logical channel classifications.

The second uplink transmission channel comprises an uplink data sharing channel UL-DSCH and an uplink semantic sharing channel UL-SSCH, wherein the function of UL-DSCH is responsible for transmitting data domain service data in uplink, and UL-SSCH is responsible for transmitting semantic domain service data in uplink. The transmission channels include, but are not limited to, the transmission channel classification in existing wireless communication systems such as RACH.

Meanwhile, in the process, UCI and USCI are extracted from PUCCH and PUSCH in the first uplink physical channel, the UCI is used for providing related control signaling, and the USCI is used for indicating a semantic channel region inside the PUSCH.

And in the process of mapping the second uplink transmission channel to the second uplink logic channel. The data field information in the UL-DSCH in the second uplink transport channel will be mapped into the CCCH, DTCH or DCCH in the first uplink logical channel depending on its specific use. Similarly, the semantic domain information in the UL-SSCH in the second uplink transport channel is mapped to the CCCH, DTCH, or DCCH in the first uplink logical channel according to its specific use.

and step C1, receiving second information source information sent by the target node, determining that the type of the second information source information is a semantic domain type, and then transparently transmitting the second information source information in the second protocol stack according to the sequence from top to bottom to obtain a third transmission signal and sending the third transmission signal to the user terminal.

In specific implementation, the transmission in the second protocol stack is divided into an uplink scenario and a downlink scenario, in the downlink scenario, as shown in fig. 3A, the second source information sent from the target node is transmitted to the intelligent profile wireless node end iNB through the user plane UPF and is transmitted in the intelligent profile air interface second protocol stack of the intelligent profile wireless node end iNB, where:

if the transmitted second information source information is of semantic domain type, transparent transmission is carried out in the SDAP layer, the PDCP layer, the RLC layer and the MAC layer, namely the second information source information only needs to be subjected to the processes of adding and decoding packet header information, channel mapping and the like in a protocol stack, and the internal data of the second information source information is not changed.

If the transmitted second source information is of the data domain type, the processing mode of the four layers is the same as that of the existing wireless communication system, namely the SDAP layer, the PDCP layer, the RLC layer and the MAC layer are processed layer by layer.

After passing through the four layers, the third transmission signal or the third transmission signal reaches the RFPHY layer, is subjected to frequency resource mapping, is converted into an electric signal, is finally sent to a wireless channel, and is transmitted to the user terminal UE through the wireless port I-Uu.

Wherein:

The second downlink transmission channel comprises a downlink data shared channel DL-DSCH and a downlink semantic shared channel DL-SSCH. The DL-DSCH is responsible for the transmission of data domain traffic data in the downlink, and the DL-SSCH is responsible for the transmission of semantic domain traffic data in the downlink. In addition, the second downlink transport channel further includes, but is not limited to, existing transport channel classifications of broadcast channel BCH, paging channel PCH, and the like.

There are PCCH, BCCH, CCCH, DTCH, DCCH channels in the second downlink logical channel. Wherein the PCCH does not carry semantic domain type information. The remaining BCCH, CCCH, DTCH, DCCH can carry either semantic domain type information or data domain type information. In the course of channel mapping from the second downlink logical channel to the second downlink transport channel, the information of semantic domain types in these channels will be mapped into DL-SSCH in the second downlink transport channel, and the information of data domain types in these channels will be mapped into DL-DSCH in the second downlink transport channel.
