Description

Technical Field

[0001] The present application relates to the field of wireless communication technology, and in particular to an information transmission method, device, communication node and storage medium. Background Art

[0002] In wireless communication technology, data is transmitted between wireless network nodes and wireless devices in the form of bits. The bits need to be channel coded and modulated to be converted into complex modulation symbols.

[0003] Channel coding is used to ensure the correct demodulation of the transmitted information to the greatest extent. The coded bits consist of information bits and check bits, and the proportion of information bits in the coded bits is considered to be the code rate. The higher the code rate, the more information the coded bits per unit length contain, but the lower the probability of correct demodulation; conversely, the lower the code rate, the less information the coded bits per unit length contain, but the higher the probability of correct demodulation. After channel coding, modulation processing is required. Modulation processing is to convert bits into modulation symbols in complex form, and the number of bits corresponding to one modulation symbol is considered to be the modulation order. The higher the modulation order, the more information a modulation symbol contains, the more information is carried per unit frequency domain resource, the higher the spectrum efficiency, but the lower the probability of correct demodulation; conversely, the lower the modulation order, the less information a modulation symbol contains, the less information is carried per unit frequency domain resource, the lower the spectrum efficiency, but the higher the probability of correct demodulation.

[0004] The modulation order and target bit rate of the data will be artificially quantized into discrete values, the modulation and coding scheme (MCS). These quantized modulation orders and target bit rates are fixed and cannot be configured, and cannot guarantee the optimal spectrum efficiency, resulting in a waste of spectrum resources.

[0026] In order to make the purpose, technical solution and advantages of the present application more clear, the embodiments of the present application will be described in detail below with reference to the accompanying drawings. It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other arbitrarily without conflict.

[0027] In existing wireless communication technologies, the modulation order and the target code rate are quantized into several non-continuous levels. Each level corresponds to a quantized modulation order and a quantized target code rate; each level corresponds to a combination of a quantized modulation order and a target code rate, namely, MCS; each level corresponds to an index, which is considered to be an MCS index. A set containing several MCSs is considered to be an MCS table. The highest modulation order and target code rate of different MCS tables may be different; the lowest modulation order and target code rate of different MCS tables may be different; the number of levels contained in different MCS tables may be different; the difference between the levels of different MCS tables may be different. Each radio access technology RAT corresponds to a set of MCS tables, and a set may contain one or more MCS tables. In the existing method, the set of MCS tables is fixed, that is, the number of MCS tables in the set is fixed, and each MCS table in the set is fixed. Furthermore, each combination of quantized modulation order and target code rate in the MCS table is fixed. The MCS table or the set of MCS tables will only be updated when the RAT standard protocol changes. However, when users use the mobile network, each MCS table is fixed. Therefore, when the air interface wireless channel cannot match the MCS table well, the fixed MCS table cannot guarantee the optimal spectrum efficiency of data transmission between the wireless network node and the wireless device.

[0028] To solve the above problems, the present application provides an information transmission method, which can effectively improve the spectrum efficiency of data transmission between wireless network nodes and wireless devices and save spectrum resources.

[0029] Figure 1 A flowchart of an information transmission method provided by an embodiment is shown in FIG. Figure 1 As shown, the information transmission method described in the embodiment of the present application is applied to a wireless device, and the method includes S110-S120:

[0030] S110. Receive configuration information of a set of modulation and coding scheme MCS tables sent by a wireless network node; wherein the wireless network node generates a set of MCS tables.

[0031] In this embodiment, the configuration information of the set of MCS tables is the quantized modulation order and the quantized target code rate corresponding to all the levels in each MCS table included in the set of MCS tables.

[0032] The wireless network node can adaptively generate a set of MCS tables and send the configuration information of the set of MCS tables generated by it to the wireless device. The wireless device can receive the configuration information of the set of modulation and coding scheme MCS tables sent by the wireless network node. Among them, the wireless network node can adaptively generate a set of MCS tables based on information such as channel information between the wireless device, communication scenarios, and capabilities of the wireless device. The set of MCS tables can include different combinations of quantized modulation orders and quantized target code rates for adapting to data transmission under different conditions.

[0033] S120. Configure a set of MCS tables based on the configuration information.

[0034] After receiving the configuration information, the wireless device configures a set of MCS tables according to the configuration information. After configuring the set of MCS tables, the wireless device can transmit data according to the set of MCS tables, that is, the wireless device can select a suitable MCS table from the set of configured MCS tables for data transmission.

[0035] According to the information transmission method provided in the embodiment of the present application, the wireless device can receive configuration information of a set of MCS tables sent by a wireless network node, the wireless network node can adaptively generate a set of MCS tables, the wireless device can configure the set of MCS tables according to the configuration information, the wireless device can perform data transmission according to the configured set of MCS tables, and the wireless network node and the wireless device perform data transmission through the adaptively generated set of MCS tables, which can optimize the spectrum efficiency of data transmission between the wireless network node and the wireless device and improve the utilization rate of spectrum resources.

[0036] In one embodiment, the method further comprises:

[0037] The capability information is reported to the radio network node, where the capability information is used to indicate whether the wireless device supports the set of MCS tables configured by the radio network node.

[0038] In this embodiment, the capability information is used to indicate whether the wireless device supports the set of MCS tables configured by the wireless network node, that is, to indicate the wireless device's ability to use the set of MCS tables configured by the wireless network node, which includes relevant information on whether the wireless device supports the set of MCS tables configured by the wireless network node.

[0039] The wireless device determines the capability information according to the software and hardware information of the device itself. If the wireless device supports the set of MCS tables configured by the wireless network node, the capability information carries the information that the wireless device supports the set of MCS tables configured by the wireless network node. If the wireless device does not support the set of MCS tables configured by the wireless network node, the capability information carries the information that the wireless device does not support the set of MCS tables configured by the wireless network node. This step may be performed before receiving the configuration information of the set of MCS tables sent by the wireless network node. If the capability information indicates that the wireless device does not support the set of MCS tables configured by the wireless network node, the wireless network node may not send the configuration information of the set of MCS tables to the wireless device. The wireless network node and the wireless device use the default set of MCS tables, that is, the set of pre-set fixed MCS tables, for example, the set of MCS tables in the 5G standard specification. If the capability information indicates that the wireless device supports the set of MCS tables configured by the wireless network node, the configuration information of the set of MCS tables is sent to the wireless device, and the wireless network node and the wireless device use the configured set of MCS tables for data transmission.

[0040] In one embodiment, receiving configuration information of a set of MCS tables sent by a wireless network node includes:

[0041] The configuration information of the set of MCS tables sent by the radio network node through layer 3 signaling is received.

[0042] The wireless network node may carry the configuration information of the set of MCS tables in layer 3 signaling, i.e., L3 signaling, and send the configuration information of the set of MCS tables to the wireless device through L3 signaling. The wireless device may receive the configuration information of the set of MCS tables through layer 3 signaling. L3 signaling includes different types of information. The wireless network node may choose to carry the configuration information of the set of MCS tables in one or more types of information according to actual service requirements and the communication connection status between the wireless device and the wireless device, and send the information to the wireless device so that the wireless device configures the set of MCS tables. The wireless device uses the most recently configured set of MCS tables until a new set of MCS tables is configured.

[0043] In one embodiment, the method further comprises:

[0044] First indication information sent by a wireless network node is received, where the first indication information includes a first index, and the first index is used to indicate an MCS table used by a wireless device when performing data transmission.

[0045] In this embodiment, the first indication information can be understood as information indicating which MCS table the wireless device uses for data transmission; the first index can be understood as an index of the MCS table, which is used to identify different MCS tables. The set of MCS tables includes one or more MCS tables, and each MCS table has a unique corresponding index.

[0046] Which MCS table in the set of MCS tables is used by the wireless device may be specified by the wireless network node. The wireless network node may also configure the index of each MCS table in the set of MCS tables to the wireless device. The wireless network node selects an index of an MCS table from the set of MCS tables as a first index, or randomly selects an index of an MCS table as a first index, generates first indication information based on the first index, carries the first index through the first indication information, and sends the first indication information to the wireless device, so that the wireless device determines which MCS table to use for data transmission after receiving the first indication information.

[0047] The wireless device can use an MCS table in the set of MCS tables for data transmission, but can only use one MCS table at a time. That is, the MCS used for one data transmission can and can only be selected from one MCS table. The wireless network node indicates an MCS table in the set of MCS tables to the wireless device for data transmission. This MCS table can be an MCS table for uplink data transmission, an MCS table for downlink data transmission, or an MCS table for sidelink data transmission. The first indication information can be sent through L3 signaling.

[0048] In one embodiment, the method further comprises:

[0049] A downlink control signaling sent by a wireless network node is received, where the downlink control signaling includes a second index, and the second index is used to indicate a layer in an MCS table used by a wireless device for data transmission.

[0050] In this embodiment, the downlink control signaling is DCI; the second index can be understood as the index of each level in the MCS table, which is used to identify the combination of quantized modulation orders and quantized target code rates at different levels in the MCS table. The MCS table includes one or more levels of quantized modulation orders and quantized target code rates, and each combination has a unique corresponding identifier.

[0051] When data transmission is required, the wireless device receives a downlink control signaling sent by a wireless network node, and the downlink control signaling includes a second index indicating the level in the MCS table used for data transmission, that is, the modulation order and the target code rate. The second index corresponds to a combination of a quantized modulation order and a quantized target code rate in the MCS table currently used by the wireless device, and the modulation order and target code rate in the combination are used for encoding and modulation of the data to be transmitted. Data transmission includes but is not limited to uplink data transmission, downlink data transmission, and sidelink data transmission. The set of MCS tables can be determined based on air interface wireless channel information or communication application scenarios. The wireless device and the wireless network node use the indicated modulation order and target code rate for data transmission.

[0052] In the information transmission method provided in the embodiment of the present application, a wireless network node adaptively generates a set of MCS tables according to wireless channel information, and configures the set of MCS tables to a wireless device through layer 3 signaling. The wireless device configures the set of MCS tables according to the configuration information. The wireless device receives the first indication information and downlink control signaling of the wireless network node and selects a matching quantized modulation order and target code rate from the set of configured MCS tables for data transmission. The combination of quantized modulation order and target code rate in the MCS table can be highly matched with the wireless channel, so that the spectrum efficiency is optimized and the utilization rate of spectrum resources is improved.

[0053] Figure 2 A flowchart of another information transmission method provided by an embodiment, such as Figure 2 As shown, the information transmission method described in the embodiment of the present application is applied to a wireless network node, and the method includes S210:

[0054] S210. Send configuration information of a set of MCS tables to a wireless device, so that the wireless device configures the set of MCS tables according to the configuration information; wherein the wireless network node generates the set of MCS tables.

[0055] In this embodiment, the configuration information of the set of MCS tables is the quantized modulation order and the quantized target code rate corresponding to all the levels in each MCS table included in the set of MCS tables.

[0056] The wireless network node can adaptively generate a set of MCS tables based on information such as channel information between the wireless device, communication scenarios, and capabilities of the wireless device. The set of MCS tables may include combinations of different quantized modulation orders and quantized target code rates to adapt to data transmission under different conditions. The wireless network node sends configuration information of the set of MCS tables to the wireless device so that the wireless device configures the set of MCS tables according to the configuration information after receiving the configuration information. After configuring the set of MCS tables, the wireless device can transmit data according to the set of MCS tables. When generating a set of MCS tables, the wireless network node can generate a corresponding set of MCS tables for each wireless device communicating with it, and send the configuration information of the corresponding set of MCS tables to each wireless device.

[0057] The information transmission method provided in the embodiment of the present application adaptively generates a set of MCS tables through a wireless network node, and sends the configuration information of the set of MCS tables to a wireless device. The wireless device can configure the set of MCS tables according to the configuration information, and the wireless device can perform data transmission according to the configured set of MCS tables. The wireless network node and the wireless device perform data transmission through the adaptively generated set of MCS tables, which can optimize the spectrum efficiency of data transmission between the wireless network node and the wireless device and improve the utilization rate of spectrum resources.

[0058] In one embodiment, generating a set of MCS tables includes:

[0059] Generate a set of MCS tables according to air interface wireless channel information;

[0060] The set of MCS tables includes one or more MCS tables, and each MCS table includes one or more levels of quantized modulation orders and quantized target code rates.

[0061] In this embodiment, the air interface wireless channel information is the air interface wireless channel information for information transmission between the wireless network node and the wireless device, and can reflect the quality of the air interface wireless channel between the wireless network node and the wireless device and channel related information.

[0062] The wireless network node communicates with the wireless device, obtains the air interface wireless channel information between the wireless network node and the wireless device, and generates a set of MCS tables according to the air interface wireless channel information. There are many ways to generate a set of MCS tables according to the air interface wireless channel information, for example, pre-setting a set of different MCS tables, and predicting a set of MCS tables corresponding to the air interface wireless channel information through a neural network model; or, predicting and processing the air interface wireless channel information through a neural network model, generating different MCS tables, and forming a set of MCS tables; or, generating different MCS tables according to an algorithm or set rules, forming a set of MCS tables, and so on.

[0063] In this embodiment, the set of MCS tables may include one or more MCS tables, each MCS table includes one or more levels of quantized modulation orders and quantized target code rates, and the wireless device may use the quantized modulation order and quantized target code rate of any level in the MCS table for data transmission. Each MCS table and each level in the MCS table may be adaptively configured, that is, the quantized values ​​of the modulation order and the target code rate may be adaptively configured.

[0064] In one embodiment, the set of MCS tables includes one or more of the following:

[0065] A collection of uplink MCS tables; a collection of downlink MCS tables; a collection of sidelink MCS tables.

[0066] Among them, the set of uplink MCS tables is determined according to the uplink channel state indication information and the wireless channel estimation; the set of downlink MCS tables is determined according to the downlink channel state indication information and the wireless channel estimation; the set of sidelink MCS tables is determined according to the sidelink channel state indication information and the wireless channel estimation.

[0067] In one embodiment, generating a set of MCS tables includes:

[0068] Generate a set of corresponding MCS tables according to the communication application scenario;

[0069] The set of MCS tables includes one or more MCS tables, and each MCS table includes one or more levels of quantized modulation orders and quantized target code rates.

[0070] In this embodiment, the communication application scenario is an application scenario in which a wireless device performs data transmission. When generating a set of MCS tables, different communication application scenarios are considered, and for each communication application scenario, a corresponding set of MCS tables is generated according to the requirements of the communication application scenario, and the number of sets of MCS tables corresponding to each communication application scenario may be one or more.

[0071] In one embodiment, generating a set of MCS tables includes:

[0072] Generate a set of corresponding MCS tables according to the communication application scenario and air interface wireless channel information;

[0073] The set of MCS tables includes one or more MCS tables, and each MCS table includes one or more levels of quantized modulation orders and quantized target code rates.

[0074] In this embodiment, the communication application scenario and the air interface wireless channel information are considered at the same time to generate a set of corresponding MCS tables. Each communication application scenario can generate a set of corresponding MCS tables according to different air interface wireless channel information, that is, the communication application scenario and the air interface wireless channel information can be freely combined to generate a set of MCS tables. There are N types of sets of MCS tables, where N = the number of communication application scenarios*the number of types of air interface wireless channel information.

[0075] In the prior art, when a wireless device uses a mobile network, each MCS table is fixed. Therefore, when the MCS table cannot match the wireless channel, the spectrum efficiency of data transmission between the wireless network node and the wireless device cannot be optimized. That is, when the quantized modulation order and the quantized target code rate in the MCS table cannot match the wireless channel, the spectrum efficiency of data transmission between the wireless network node and the wireless device is not optimal. In other words, the optimal modulation order and target code rate corresponding to the wireless channel cannot fall exactly on the level (quantized modulation order and target code rate combination) in the MCS table, but fall between two levels. However, wireless network nodes and wireless devices can only select the quantized values ​​of the modulation order and target code rate corresponding to the level, which will make the spectrum efficiency not optimal.

[0076] In this embodiment, the wireless network device generates a set of MCS tables and all MCS tables in the set according to the air interface wireless channel information between the wireless device and the wireless device. The set of MCS tables is not fixed but configurable. Further, the wireless network device generates a quantized modulation order and a target code rate combination, or a quantized modulation order, or a quantized target code rate in the MCS table according to the wireless channel. The quantized modulation order and the quantized target code rate combination in the MCS table are configurable, which can ensure optimal spectrum efficiency.

[0077] In one embodiment, a set of corresponding MCS tables is generated according to the communication application scenario and the air interface wireless channel information, including:

[0078] The vectors corresponding to the communication application scenario and the air interface wireless channel information are input into a deep neural network, and the deep neural network outputs the probability of a set of multiple candidate MCS tables;

[0079] The probabilities of a plurality of candidate MCS table sets are compared, and the MCS table set with the highest probability is used as the MCS table set to be configured for the wireless device.

[0080] In this embodiment, the deep neural network model can be pre-trained, and training samples can be obtained in advance, the training samples include communication application scenarios, air interface wireless channel information, and the association probability between the two and each candidate MCS table set; the deep neural network is trained based on the training samples to obtain a deep neural network that meets the requirements. The deep neural network can be predicted based on each communication application scenario. The deep neural network can be predicted based on each air interface wireless channel information. The deep neural network model can be jointly trained by multiple communication application scenarios. The deep neural network model can be jointly trained by multiple air interface wireless channel information.

[0081] Determine the vector corresponding to the air interface wireless channel information. The vector corresponding to the air interface wireless channel information can be converted by the wireless network node according to the air interface wireless channel information, or can be converted by the wireless device and sent to the wireless network node. Input the vector corresponding to the communication application scenario and the air interface wireless channel information into the deep neural network. The deep neural network predicts based on the knowledge learned during the training process to determine the probability of the communication application scenario and the air interface wireless channel information matching each set of candidate MCS tables. The set of candidate MCS tables can be preset, and the number is usually multiple.

[0082] The probabilities of a plurality of candidate MCS table sets are compared to determine a set of MCS tables with the highest probability, and this set of MCS tables is used as a set of MCS tables to be configured for the wireless device.

[0083] This embodiment may also sort the probabilities, select a set of a preset number of MCS tables in order of probability from large to small, and use them as the set of MCS tables configured for the wireless device. In this way, a set of multiple MCS tables with the highest probability may be selected as the set of MCS tables configured for the wireless device, that is, the wireless device may be configured with a set of multiple MCS tables.

[0084] When a set of corresponding MCS tables is generated according to the communication application scenario and the air interface wireless channel information, a set of MCS tables can be generated for each combination of the communication application scenario and the air interface wireless channel information, and configured to the wireless device. When a set of MCS tables is configured to the wireless device, a set of corresponding MCS tables can be selected according to the communication application scenario and the air interface wireless channel information requirements of the wireless device at this time, and the configuration information can be sent to the wireless device so that the wireless device can be configured.

[0085] In one embodiment, the communication application scenarios include one or more of the following: enhanced mobile bandwidth eMBB; ultra-reliable low latency communication URLLC; massive machine type communication mMTC.

[0086] In one embodiment, the air interface wireless channel information includes one or more of the following:

[0087] Channel state indication CSI information; wireless channel estimation.

[0088] In this embodiment, the channel state indication CSI information may be uplink channel state indication CSI information, downlink channel state indication CSI information, and sidelink channel state indication CSI information.

[0089] The radio network node may obtain CSI information by receiving downlink CSI fed back by the wireless device, or by receiving uplink reference signals (e.g., SRS) to measure the uplink radio channel. The radio network node obtains the state of the downlink radio channel through the downlink CSI fed back by the wireless device; or, the radio network node estimates the uplink radio channel by receiving the SRS sent by the wireless device, thereby obtaining the state of the uplink radio channel.

[0090] Taking the communication application scenarios including eMBB, URLLC and mMTC, and the channel state indication CSI information including uplink CSI information, downlink CSI information and sidelink CSI information as an example, each communication application scenario can determine a set of three types of MCS tables, including: a set of uplink MCS tables, a set of downlink MCS tables, a set of sidelink MCS tables, a total of 9 sets of MCS tables.

[0091] In one embodiment, the method further comprises:

[0092] Capability information reported by a wireless device is received, where the capability information is used to indicate whether the wireless device supports a set of MCS tables configured by the wireless network node.

[0093] The wireless device determines the capability information according to the software and hardware information of the device itself. If the wireless device supports the set of MCS tables configured by the wireless network node, the capability information carries the information that the wireless device supports the set of MCS tables configured by the wireless network node. If the wireless device does not support the set of MCS tables configured by the wireless network node, the capability information carries the information that the wireless device does not support the set of MCS tables configured by the wireless network node. This step may be performed before sending the configuration information of the set of MCS tables to the wireless device. If the capability information indicates that the wireless device does not support the set of MCS tables configured by the wireless network node, the wireless network node may not send the configuration information of the set of MCS tables to the wireless device. The wireless network node and the wireless device use the default set of MCS tables, that is, the set of pre-set fixed MCS tables, for example, the set of MCS tables in the 5G standard specification. If the capability information indicates that the wireless device supports the set of MCS tables configured by the wireless network node, the configuration information of the set of MCS tables is sent to the wireless device, and the wireless network node and the wireless device use the configured set of MCS tables for data transmission.

[0094] In one embodiment, sending configuration information of a set of MCS tables to a wireless device includes: sending configuration information of a set of MCS tables to the wireless device through layer 3 signaling:

[0095] The radio network node may carry the configuration information of the set of MCS tables in layer 3 signaling, i.e., L3 signaling, and send the configuration information of the set of MCS tables to the wireless device through L3 signaling. L3 signaling includes different types of information. The radio network node may choose to carry the configuration information of the set of MCS tables in one or more types of information according to actual service requirements and the communication connection status between the wireless device and the wireless device, and send the information to the wireless device so that the wireless device configures the set of MCS tables. The wireless device uses the most recently configured set of MCS tables until a new set of MCS tables is configured.

[0096] In one embodiment, the method further comprises:

[0097] First indication information is sent to a wireless device, where the first indication information includes a first index, and the first index is used to indicate an MCS table used by the wireless device when performing data transmission.

[0098] The wireless network node can also configure the index of each MCS table in the set of MCS tables to the wireless device. After sending the configuration information of the set of MCS tables to the wireless device, the wireless network node selects an index of an MCS table from the set of MCS tables as the first index according to the state of the wireless channel, the communication application scenario, the software and hardware information of the wireless device, etc., or randomly selects an index of an MCS table as the first index, generates first indication information based on the first index, carries the first index through the first indication information, and sends the first indication information to the wireless device, so that the wireless device determines which MCS table to use for data transmission after receiving the first indication information.

[0099] The wireless device can use an MCS table in the set of MCS tables for data transmission, but can only use one MCS table at a time. That is, the MCS used for one data transmission can and can only be selected from one MCS table. The wireless network node indicates an MCS table in the set of MCS tables to the wireless device for data transmission. This MCS table can be an MCS table for uplink data transmission, an MCS table for downlink data transmission, or an MCS table for sidelink data transmission. The first indication information can be sent through L3 signaling.

[0100] In one embodiment, the method further comprises:

[0101] A downlink control signaling is sent to the wireless device, where the downlink control signaling includes a second index, and the second index is used to indicate a layer in the MCS table used by the wireless device for data transmission.

[0102] When data needs to be transmitted, the wireless network node sends a downlink control signaling to the wireless device, indicating a second index for the wireless device, and the modulation order and target code rate corresponding to the second index are used for the data transmission to be performed. The second index corresponds to a combination of a quantized modulation order and a quantized target code rate in the MCS table currently used by the wireless device, and the modulation order and target code rate in the combination are used for the encoding and modulation of the data to be transmitted. The data transmission includes but is not limited to uplink data transmission, downlink data transmission, and sidelink data transmission.

[0103] After the wireless device determines the MCS table to be used, when data needs to be transmitted, the wireless device receives downlink control signaling sent by the wireless network node, including a second index indicating a level in the MCS table used for data transmission, that is, a modulation order and a target code rate, and the wireless device and the wireless network node use the indicated modulation order and target code rate for data transmission. The combination of the quantized modulation order and the quantized target code rate corresponding to the second index is generated according to the air interface wireless channel information.

[0104] In the information transmission method provided in the embodiment of the present application, a wireless network node adaptively generates a set of MCS tables according to wireless channel information, and configures the set of MCS tables to a wireless device through layer 3 signaling; the wireless device configures the set of MCS tables according to the configuration information; the wireless device and the wireless network node can transmit data according to the configured set of MCS tables; the quantized modulation order and target code rate combination in the MCS table can be highly matched with the air interface wireless channel, so that the spectrum efficiency is optimized and the utilization rate of spectrum resources is improved; and, the embodiment of the present application simultaneously generates a corresponding set of MCS tables for each communication application scenario and air interface wireless channel information, so as to facilitate the selection of a suitable set of MCS tables for each communication application scenario and air interface wireless channel information, further improving the utilization rate of spectrum resources and avoiding the waste of frequency resources.

[0105] The information transmission process is described through the following embodiments:

[0106] Example 1

[0107] After the wireless device establishes a connection with the wireless network node, the wireless network node generates a set of MCS tables based on the air interface wireless channel information between the wireless device and the wireless network node. That is, the wireless network node generates all MCS tables in the set based on the air interface wireless channel information. Further, for each MCS table, the wireless network node generates a combination of the quantized modulation order and the quantized target code rate corresponding to each level in the table based on the wireless channel information, that is, the quantized modulation order and the quantized target code rate corresponding to each level.

[0108] Among them, the air interface wireless channel information includes but is not limited to: channel state indication (CSI) information, wireless channel estimation. The channel state indication information includes uplink channel state indication information, downlink channel state indication information, and sidelink channel state indication information. The way in which the wireless network node obtains the channel state indication information includes: receiving the downlink CSI fed back by the wireless device, or receiving the measurement of the uplink wireless channel by a reference signal such as SRS. The wireless network node obtains the state of the downlink wireless channel through the downlink channel state indication CSI information fed back by the wireless device. The wireless network node estimates the uplink wireless channel by receiving the SRS sent by the wireless device to obtain the uplink wireless channel state. The wireless network node can generate a set of MCS tables based on the statistical information of the air interface wireless channel within a period of time; or, the wireless network node can generate a set of MCS tables based on the instantaneous information of the wireless channel.

[0109] The wireless network node generates a set of uplink MCS tables according to the uplink wireless channel; the wireless network node generates a set of downlink MCS tables according to the downlink wireless channel. The wireless network node generates a corresponding set of independent MCS tables for each communication application scenario (for example: eMBB, URLLC, mMTC). For example, the three communication application scenarios of eMBB, URLLC, and mMTC correspond to at least nine sets of independent MCS tables, and each communication application scenario corresponds to at least three sets, namely, a set of uplink MCS tables, a set of downlink MCS tables, and a set of sidelink MCS tables. The sets of MCS tables for different communication application scenarios can contain the same MCS tables.

[0110] The wireless device reports capability information to the wireless network node, indicating whether the wireless device supports the set of MCS tables configured by the wireless network node. If the capability information indicates that the wireless device supports the set of MCS tables configured by the wireless network node, the wireless network node sends configuration information of the set of MCS tables to the wireless device, the wireless device configures the set of MCS tables according to the configuration information, and the wireless network node and the wireless device use the configured set of MCS tables. If the capability information indicates that the wireless device does not support the set of MCS tables configured by the wireless network node, the wireless network node and the wireless device use the default set of MCS tables, that is, the set of pre-set fixed MCS tables. For example, the set of MCS tables in the 5G standard specification. The default set of MCS tables is fixed unless the standard specification is modified.

[0111] When the capability information of the wireless device indicates support for using a set of configured MCS tables, the wireless network node sends configuration information of the set of MCS tables to the wireless device, and the wireless device configures the set of MCS tables according to the configuration information and uses the set of configured MCS tables. The wireless device uses the set of MCS tables configured most recently until a new set of MCS tables is configured. The wireless network node sends the configuration information of the set of MCS tables to the wireless device through L3 signaling. Wherein, L3 signaling includes but is not limited to: a radio resource control RRC message. The RRC message includes a radio resource control establishment message RRCsetup, or a radio resource control reconfiguration message RRCReconfiguration, or a radio resource control reconfiguration message with synchronization ReconfigurationWithSync, or system information. The system information includes: a system message block SIB1. Further, the system message received by the wireless device in an idle state (IDLE state) or an inactive state (INACTIVE state) contains the configuration information of the set of MCS tables, and the RRCsetup and / or RRCReconfiguration received by the wireless device in a connected state contain the configuration information of the set of MCS tables. During the cell switching process, the ReconfigurationWithSync received by the wireless device includes the configuration information of the set of MCS tables. The configuration information of the set of MCS tables can be modified through high-level signaling, and the high-level signaling includes: RRCReconfiguration.

[0112] After the wireless device completes the configuration of the set of MCS tables, the wireless network node sends a first indication message to the wireless device, indicating that an MCS table in the set of MCS tables is used to determine the modulation order and target code rate of the data. The first indication message indicates an MCS table index, and the MCS table corresponding to the first index is the indicated MCS table. The wireless device determines the MCS table to be used according to the first index in the indication message. The wireless device uses the most recently indicated MCS table until a new MCS table is indicated. The wireless network node sends the first indication message to the wireless device via L3 signaling. Wherein, L3 signaling includes but is not limited to: RRC message. The RRC message includes RRCsetup, or RRCReconfiguration, or ReconfigurationWithSync, or system information. The system information includes: SIB1. Further, the system message received by the wireless device in IDLE state or INACTIVE state includes the first indication message, and the RRCsetup and / or RRCReconfiguration received by the wireless device in connected state include the first indication message. During the cell switching process, the ReconfigurationWithSync received by the wireless device includes the first indication message. The first indication information may be modified through high-layer signaling, and the high-layer signaling includes: RRCReconfiguration.

[0113] After the wireless device is indicated with the MCS table, when data needs to be transmitted, the wireless network node indicates the second index to the wireless device through the downlink control signaling DCI. The second index corresponds to a level in the MCS table, that is, a combination of a quantized modulation order and a quantized target code rate. The wireless device determines the modulation order and target code rate of the data to be transmitted according to the second index. The wireless device and the wireless network node perform data transmission based on the determined modulation order and target code rate, wherein the MCS table described in this step is an MCS table for determining the modulation order and target code rate of the data indicated by the wireless network node to the wireless device in the set of configured MCS tables.

The first AI node of the wireless network node will model a mapping relationship, which can map the communication scenario requirements and air interface wireless channel information obtained by the wireless network node to the configuration information of the set of MCS tables.

[0123] The first AI node uses the paradigm of deep neural network to model the mapping relationship, where deep neural networks include: feedforward neural network, convolutional neural network, recurrent neural network. A deep neural network consists of an input layer, an output layer, and several (N greater than or equal to 1) hidden layers. The input layer, output layer, and each hidden layer are composed of one or more neuron nodes.

[0124] The first AI node processes the communication application scenario and the air interface wireless channel information into a D-dimensional vector, where D is greater than or equal to 1. The vector is input to the input layer, passes through N hidden layers, and reaches the output layer. The output layer outputs the probability corresponding to each set of MCS tables. The wireless network node selects the set of MCS tables with the highest probability as the set of MCS tables configured for the wireless device.

[0125] The second AI node of the wireless device encodes the downlink air interface wireless channel information including: CSI, air interface channel estimation matrix, eigenvalues ​​and eigenvectors of the air interface channel estimation matrix, singular values, left singular matrices and right singular matrices of the air interface channel estimation matrix, and sends the encoded information to the first AI node of the wireless network node.
