Description

Information transmission method, device, communication node and storage medium Technical Field

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

[0002] In wireless communication, data is transmitted between wireless network nodes and wireless devices in the form of bits. These bits undergo channel coding and modulation, converting them into complex modulation symbols.

[0003] Channel coding is used to maximize the guarantee of correct demodulation of transmitted information. Coded bits consist of information bits and parity bits, and the ratio of information bits to the total coded bits is considered the code rate. A higher code rate contains more information per coded bit length, but the probability of correct demodulation decreases. Conversely, a lower code rate contains less information per coded bit length, but the probability of correct demodulation increases. After channel coding, modulation is required. Modulation converts bits into complex modulation symbols. The number of bits corresponding to a modulation symbol is considered the modulation order. A higher modulation order contains more information per modulation symbol, carrying more information per unit frequency domain resource, and improving spectral efficiency, but reducing the probability of correct demodulation. Conversely, a lower modulation order contains less information per modulation symbol, carrying less information per unit frequency domain resource, and reducing spectral efficiency, but increasing the probability of correct demodulation.

[0004] The data modulation order and target bit rate are artificially quantized into discrete values, called the Modulation and Coding Scheme (MCS). These quantized modulation orders and target bit rates are fixed and non-configurable, making it impossible to guarantee optimal spectrum efficiency and resulting in wasted spectrum resources.

[0027] To make the purpose, technical solutions and advantages of this application more clear, the embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be noted that, unless there is a conflict, the embodiments and features in the embodiments of this application can be combined with each other in any way.

[0028] In existing wireless communication technologies, the modulation order and target code rate are quantized into several non-contiguous levels. Each level corresponds to a quantized modulation order and a quantized target code rate; each level corresponds to a quantized modulation order and target code rate combination, known as the MCS; and each level corresponds to an index, known as an MCS index. A set of several MCSs is known as an MCS table. Different MCS tables can have different maximum modulation orders and target code rates; different MCS tables can have different minimum modulation orders and target code rates; different MCS tables can contain different numbers of levels; and different MCS tables can have different differences between levels. Each radio access technology (RAT) corresponds to a set of MCS tables, and a set can contain one or more MCS tables. In existing methods, the set of MCS tables is fixed, meaning the number of MCS tables in the set is fixed, and each MCS table in the set is fixed. Furthermore, each quantized modulation order and target code rate combination in the MCS table is fixed. The MCS table or set of MCS tables is updated only when the RAT standard protocol changes. However, each MCS table remains static while a user is using the mobile network. Therefore, when the air interface radio channel does not perfectly match the MCS table, a fixed MCS table cannot guarantee optimal spectral efficiency for data transmission between wireless network nodes and wireless devices.

[0029] 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.

[0030] FIG1 is a flow chart of an information transmission method provided by an embodiment. As shown in FIG1 , the information transmission method according to the embodiment of the present application is applied to a wireless device. The method includes S110 to S120:

[0031] 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 the set of MCS tables.

[0032] 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 levels in each MCS table included in the set of MCS tables.

[0033] The radio network node can adaptively generate a set of MCS tables and send configuration information of the generated set of MCS tables 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 radio network node. The radio network node can adaptively generate the set of MCS tables based on information such as channel information between the radio network node and the wireless device, the communication scenario, and the capabilities of the wireless device. The set of MCS tables can include different combinations of quantized modulation orders and quantized target bit rates to adapt to data transmission under different conditions.

[0034] S120. Configure a set of MCS tables based on the configuration information.

[0035] 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.

[0036] The information transmission method provided in the embodiment of the present application is that 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, and the wireless device can perform data transmission according to the configured set of MCS tables. Data transmission between the wireless network node and the wireless device through the adaptively generated set of MCS tables can optimize the spectrum efficiency of data transmission between the wireless network node and the wireless device, thereby improving the utilization of spectrum resources.

[0037] In one embodiment, the method further comprises:

[0038] Report capability information 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.

[0039] 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.

[0040] The wireless device determines capability information based on its own software and hardware information. If the wireless device supports the use of the set of MCS tables configured by the radio network node, the capability information includes information indicating that the wireless device supports the use of the set of MCS tables configured by the radio network node. If the wireless device does not support the use of the set of MCS tables configured by the radio network node, the capability information includes information indicating that the wireless device does not support the use of the set of MCS tables configured by the radio network node. This step may be performed before receiving configuration information regarding the set of MCS tables sent by the radio network node. If the capability information indicates that the wireless device does not support the use of the set of MCS tables configured by the radio network node, the radio network node may not send the configuration information regarding the set of MCS tables to the wireless device. The radio network node and the wireless device use a default set of MCS tables, i.e., a pre-set, fixed set of MCS tables, such as the set of MCS tables in the 5G standard. If the capability information indicates that the wireless device supports the use of the set of MCS tables configured by the radio network node, the configuration information regarding the set of MCS tables is sent to the wireless device, and the radio network node and the wireless device use the configured set of MCS tables for data transmission.

[0041] In one embodiment, receiving configuration information of a set of MCS tables sent by a wireless network node includes:

[0042] The configuration information of the MCS table set is received and sent by the radio network node through layer 3 signaling.

[0043] A radio network node can carry configuration information about a set of MCS tables in Layer 3 signaling (L3 signaling) and send the MCS table configuration information to a wireless device via L3 signaling. The wireless device can receive the MCS table configuration information via Layer 3 signaling. L3 signaling includes different types of information. The radio network node can choose to carry the MCS table configuration information in one or more types of information based on actual service requirements and the communication connection between the radio network node and the wireless device, and send the information to the wireless device to facilitate configuration of the MCS table set. The wireless device uses the most recently configured MCS table set until a new MCS table set is configured.

[0044] In one embodiment, the method further comprises:

[0045] 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 for data transmission.

[0046] In this embodiment, the first indication information may be understood as information indicating which MCS table the wireless device uses for data transmission; the first index may be understood as an index of the MCS table, 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.

[0047] The radio network node may specify which MCS table in the set of MCS tables to use for the wireless device. The radio network node may also configure the wireless device with the index of each MCS table in the set of MCS tables. The radio 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 the first index, generates first indication information based on the first index, carries the first index in 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.

[0048] A wireless device can use an MCS table from the set of MCS tables for data transmission, but can only use one MCS table at a time. That is, the MCS used for a data transmission can be selected from one and only one MCS table. The radio network node indicates an MCS table from 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 via L3 signaling.

[0049] In one embodiment, the method further comprises:

[0050] 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.

[0051] In this embodiment, the downlink control signaling is downlink control information (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 of 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.

[0052] When data transmission is required, the wireless device receives downlink control signaling sent by the radio network node. 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. 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 radio network node use the indicated modulation order and target code rate for data transmission.

[0053] In the information transmission method provided in the embodiments of the present application, a wireless network node adaptively generates a set of MCS tables based on 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 based on the configuration information. The wireless device receives first indication information and downlink control signaling from 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, thereby optimizing spectrum efficiency and improving the utilization of spectrum resources.

[0054] FIG2 is a flow chart of another information transmission method provided by an embodiment. As shown in FIG2 , the information transmission method according to the embodiment of the present application is applied to a wireless network node. The method includes S210:

[0055] 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.

[0056] 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 levels in each MCS table included in the set of MCS tables.

[0057] The radio network node can adaptively generate a set of MCS tables based on information such as channel information between the node and the wireless device, the communication scenario, and the capabilities of the wireless device. The set of MCS tables can include combinations of different quantized modulation orders and quantized target code rates to adapt to data transmission under different conditions. The radio network node sends configuration information about the set of MCS tables to the wireless device, so that the wireless device configures the set of MCS tables based on the configuration information after receiving the configuration information. After configuring the set of MCS tables, the wireless device can transmit data based on the set of MCS tables. When generating the set of MCS tables, the radio network node can generate a corresponding set of MCS tables for each wireless device communicating with it and send the corresponding set of MCS tables configuration information to each wireless device.

[0058] 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 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. Data transmission between the wireless network node and the wireless device is performed 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 of spectrum resources.

[0059] In one embodiment, generating a set of MCS tables includes:

[0060] Generate a set of MCS tables based on air interface wireless channel information;

[0061] 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.

[0062] In this embodiment, the air interface wireless channel information is 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.

[0063] A wireless network node communicates with a wireless device to obtain air interface wireless channel information between the wireless network node and the wireless device, and generates a set of MCS tables based on the air interface wireless channel information. There are various ways to generate a set of MCS tables based on the air interface wireless channel information, such as presetting a set of different MCS tables and predicting the set of MCS tables corresponding to the air interface wireless channel information using a neural network model; or predicting and processing the air interface wireless channel information using a neural network model to generate different MCS tables and form a set of MCS tables; or generating different MCS tables based on an algorithm or set rules to form a set of MCS tables, etc.

[0064] In this embodiment, the set of MCS tables may include one or more MCS tables. Each MCS table includes quantized modulation orders and quantized target bit rates for one or more levels. A wireless device may use the quantized modulation order and quantized target bit rate for any level in the MCS table for data transmission. Each MCS table, and each level in the MCS table, is adaptively configurable, meaning that the quantized values ​​of the modulation order and target bit rate are adaptively configurable.

[0065] In one embodiment, the set of MCS tables includes one or more of the following:

[0066] A collection of uplink MCS tables; a collection of downlink MCS tables; a collection of sidelink MCS tables.

[0067] 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.

[0068] In one embodiment, generating a set of MCS tables includes:

[0069] Generate a set of corresponding MCS tables according to the communication application scenario;

[0070] 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.

[0071] 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. For each communication application scenario, a corresponding set of MCS tables is generated based on the requirements of the communication application scenario. The number of sets of MCS tables corresponding to each communication application scenario can be one or more.

[0072] In one embodiment, generating a set of MCS tables includes:

[0073] Generate a set of corresponding MCS tables based on the communication application scenario and air interface wireless channel information;

[0074] 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.

[0075] In this embodiment, both communication application scenarios and air interface wireless channel information are considered to generate a corresponding set of MCS tables. Each communication application scenario can generate a corresponding set of MCS tables based on different air interface wireless channel information. That is, communication application scenarios and air interface wireless channel information can be freely combined to generate a set of MCS tables. There are N types of MCS table sets, where N = the number of communication application scenarios * the number of air interface wireless channel information types.

[0076] In the related 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 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, the wireless network node and the wireless device 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.

[0077] In this embodiment, the wireless network device generates a set of MCS tables and all MCS tables in the set based on air interface wireless channel information between the wireless device and the wireless device. The set of MCS tables is not fixed but configurable. Furthermore, the wireless network device generates a quantized modulation order and target bit rate combination, or a quantized modulation order, or a quantized target bit rate in the MCS table based on the wireless channel. The quantized modulation order and target bit rate combination in the MCS table is configurable, ensuring optimal spectral efficiency.

[0078] In one embodiment, a set of corresponding MCS tables is generated according to the communication application scenario and air interface wireless channel information, including:

[0079] Input the vectors corresponding to the communication application scenario and the air interface wireless channel information into the deep neural network, and the deep neural network outputs the probability of a set of multiple candidate MCS tables;

[0080] The probabilities of multiple candidate MCS table sets are compared, and the MCS table set with the highest probability is used as the MCS table set configured for the wireless device.

[0081] In this embodiment, a deep neural network model can be pre-trained by obtaining training samples. The training samples include communication application scenarios, air interface wireless channel information, and the probability of association 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 make predictions based on each communication application scenario. The deep neural network can make predictions based on each type of air interface wireless channel information. The deep neural network model can be jointly trained based on multiple communication application scenarios. The deep neural network model can be jointly trained based on multiple types of air interface wireless channel information.

[0082] A vector corresponding to the air interface wireless channel information is determined. The vector corresponding to the air interface wireless channel information can be converted by the wireless network node based on the air interface wireless channel information, or by the wireless device and sent to the wireless network node. The vectors corresponding to the communication application scenario and the air interface wireless channel information are input into a deep neural network. The deep neural network makes predictions based on the knowledge learned during training to determine the probability that the communication application scenario and the air interface wireless channel information match each set of candidate MCS tables. The set of candidate MCS tables can be preset, and the number of candidate MCS tables is typically multiple.

[0083] The probabilities of multiple candidate MCS table sets are compared to determine the MCS table set with the highest probability, and this MCS table set is used as the MCS table set to be configured for the wireless device.

[0084] This embodiment may further sort the probabilities and select a preset number of MCS table sets in descending order of probability as the set of MCS tables configured for the wireless device. In this manner, 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 multiple sets of MCS tables.

[0085] When generating a corresponding MCS table set based on a communication application scenario and air interface wireless channel information, an MCS table set can be generated for each combination of communication application scenario and air interface wireless channel information and configured for the wireless device. When configuring the MCS table set for the wireless device, a corresponding MCS table set can be selected based on the current communication application scenario and air interface wireless channel information requirements of the wireless device, and the configuration information can be sent to the wireless device for configuration.

[0086] In one embodiment, the communication application scenarios include one or more of the following: enhanced mobile broadband (eMBB); ultra-reliable low-latency communication (URLLC); massive machine-type communication (mMTC).

[0087] In one embodiment, the air interface wireless channel information includes one or more of the following:

[0088] Channel State Indication (CSI) information; wireless channel estimation.

[0089] 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.

[0090] Radio network nodes can obtain CSI information by receiving downlink CSI from wireless devices or by measuring the uplink radio channel using uplink reference signals (e.g., Sounding Reference Signals (SRS)). Radio network nodes use downlink CSI from wireless devices to determine the state of the downlink radio channel. Alternatively, radio network nodes can estimate the uplink radio channel by receiving SRSs from wireless devices.

[0091] 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, and a set of sidelink MCS tables, a total of 9 sets of MCS tables.

[0092] In one embodiment, the method further comprises:

[0093] 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 radio network node.

[0094] The wireless device determines capability information based on its own software and hardware information. If the wireless device supports the use of a set of MCS tables configured by the radio network node, the capability information includes information indicating that the wireless device supports the use of the set of MCS tables configured by the radio network node. If the wireless device does not support the use of the set of MCS tables configured by the radio network node, the capability information includes information indicating that the wireless device does not support the use of the set of MCS tables configured by the radio network node. This step may be performed before sending configuration information regarding the set of MCS tables to the wireless device. If the capability information indicates that the wireless device does not support the use of the set of MCS tables configured by the radio network node, the radio network node may not send the configuration information regarding the set of MCS tables to the wireless device. The radio network node and the wireless device use a default set of MCS tables, i.e., a pre-set, fixed set of MCS tables, such as the set of MCS tables in the 5G standard. If the capability information indicates that the wireless device supports the use of the set of MCS tables configured by the radio network node, the configuration information regarding the set of MCS tables is sent to the wireless device, and the radio network node and the wireless device use the configured set of MCS tables for data transmission.

[0095] In one embodiment, sending configuration information of a set of MCS tables to the wireless device includes: sending the configuration information of the set of MCS tables to the wireless device through layer 3 signaling:

[0096] A radio network node can carry MCS table set configuration information in Layer 3 signaling (L3 signaling) and send the MCS table set configuration information to a wireless device via L3 signaling. L3 signaling includes different types of information. Based on actual service requirements and the communication connection status between the radio network node and the wireless device, the radio network node can choose to carry the MCS table set configuration information in one or more types of information and send them to the wireless device, so that the wireless device can configure the MCS table set. The wireless device uses the most recently configured MCS table set until a new MCS table set is configured.

[0097] In one embodiment, the method further comprises:

[0098] 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.

[0099] The radio 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 radio network node selects an MCS table index from the set of MCS tables as a first index, or randomly selects an MCS table index as the first index based on the state of the wireless channel, the communication application scenario, and the software and hardware information of the wireless device. The node generates first indication information based on the first index, carries the first index in 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.

[0100] A wireless device can use an MCS table from the set of MCS tables for data transmission, but can only use one MCS table at a time. That is, the MCS used for a data transmission can be selected from one and only one MCS table. The radio network node indicates an MCS table from 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 via L3 signaling.

[0101] In one embodiment, the method further comprises:

[0102] A downlink control signaling is sent to the wireless device, where the downlink control signaling includes a second index, where the second index is used to indicate a layer in the MCS table used by the wireless device for data transmission.

[0103] When data needs to be transmitted, the radio network node sends downlink control signaling to the wireless device, indicating a second index to the wireless device. The modulation order and target code rate corresponding to the second index are used for the upcoming data transmission. The second index corresponds to a quantized modulation order and quantized target code rate combination in the MCS table currently used by the wireless device. The modulation order and target code rate in this 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.

[0104] After the wireless device determines the MCS table to use, when data needs to be transmitted, the wireless device receives downlink control signaling from the radio network node, which includes a second index indicating a level in the MCS table used for data transmission, namely, a modulation order and a target bit rate. The wireless device and the radio network node then use the indicated modulation order and target bit rate for data transmission. The combination of the quantized modulation order and the quantized target bit rate corresponding to the second index is generated based on air interface radio channel information.

[0105] The information transmission method provided in the embodiment of the present application is that the wireless network node adaptively generates a set of MCS tables based on wireless channel information, and configures the set of MCS tables to the wireless device through layer 3 signaling. The wireless device configures the set of MCS tables based on the configuration information. The wireless device and the wireless network node can perform data transmission according to the set of configured 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, which facilitates 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.

[0106] The information transmission process is described through the following examples:

[0107] Example 1

[0108] After a wireless device establishes a connection with a 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 node. Specifically, the wireless network node generates all MCS tables in the set based on the air interface wireless channel information. Furthermore, 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. Specifically, the quantized modulation order and the quantized target code rate corresponding to each level are generated.

[0109] 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 radio network node obtains the channel state indication information includes: receiving downlink CSI fed back by the wireless device, or receiving a reference signal such as SRS to measure the uplink wireless channel. The radio 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 radio network node estimates the uplink wireless channel by receiving the SRS sent by the wireless device, thereby obtaining the uplink wireless channel state. The radio 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 radio network node can generate a set of MCS tables based on the instantaneous information of the wireless channel.

[0110] The radio network node generates a set of uplink MCS tables based on the uplink radio channel; the radio network node generates a set of downlink MCS tables based on the downlink radio channel. The radio 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 table.

[0111] The wireless device reports capability information to the radio network node, indicating whether the wireless device supports the set of MCS tables configured by the radio network node. If the capability information indicates that the wireless device supports the set of MCS tables configured by the radio network node, the radio network node sends configuration information of the set of MCS tables to the wireless device, the wireless device configures the set of MCS tables based on the configuration information, and the radio 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 radio network node, the radio network node and the wireless device use a default set of MCS tables, i.e., a preset, fixed set of 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.

[0112] When the capability information of the wireless device indicates support for the use of the configured MCS table set, the radio network node sends configuration information for the MCS table set to the wireless device. The wireless device configures the MCS table set according to the configuration information and uses the configured MCS table set. The wireless device uses the most recently configured MCS table set until a new MCS table set is configured. The radio network node sends the configuration information for the MCS table set to the wireless device via Layer 3 signaling. Layer 3 signaling includes, but is not limited to, Radio Resource Control (RRC) messages. The RRC messages include a Radio Resource Control setup message (RRCsetup), a Radio Resource Control reconfiguration message (RRCReconfiguration), a Radio Resource Control reconfiguration message (ReconfigurationWithSync), or system information. The system information includes System Information Block (SIB) 1. Furthermore, system messages received by wireless devices in idle or inactive states include configuration information for a set of MCS tables, and RRCsetup and / or RRCReconfiguration messages received by wireless devices in connected states include configuration information for a set of MCS tables. During a cell handover, ReconfigurationWithSync messages received by the wireless device include configuration information for a set of MCS tables. The configuration information for a set of MCS tables can be modified via higher-layer signaling, including RRCReconfiguration.

[0113] After the wireless device completes configuration of a set of MCS tables, the radio network node sends first indication information 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 data. The first indication information 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 use based on the first index in the indication information. The wireless device uses the most recently indicated MCS table until a new MCS table is indicated. The radio network node sends the first indication information to the wireless device via Layer 3 signaling. The Layer 3 signaling includes, but is not limited to, an RRC message. The RRC message includes RRCsetup, RRCReconfiguration, ReconfigurationWithSync, or system information. The system information includes SIB1. Furthermore, a system message received by a wireless device in IDLE or INACTIVE state includes the first indication information, and an RRCsetup and / or RRCReconfiguration received by a wireless device in connected state includes the first indication information. During a cell handover, a ReconfigurationWithSync message received by the wireless device includes the first indication information. The first indication information may be modified through higher layer signaling, where the higher layer signaling includes: RRCReconfiguration.

[0114] After the wireless device is instructed to use the MCS table, when data needs to be transmitted, the radio network node indicates a second index to the wireless device via downlink control signaling (DCI). The second index corresponds to a level in the MCS table, i.e., a combination of a quantized modulation order and a quantized target code rate. The wireless device determines the modulation order and target code rate for the data to be transmitted based on the second index. The wireless device and the radio network node perform data transmission based on the determined modulation order and target code rate. The MCS table in this step is an MCS table, from a set of configured MCS tables, that the radio network node indicates to the wireless device for determining the modulation order and target code rate for the data.

[0115] FIG3 provides an example flow chart of information transmission. As shown in FIG3 , the processing flow of this method includes:

[0116] S310: The wireless device reports capability information to the wireless network node, indicating that the wireless device supports the use of the configured MCS table set;

[0120] S350: The wireless device determines the MCS table to be used according to the indicated first index.

[0121] Example 2

[0122] The wireless network node uses artificial intelligence (AI) to determine a set of MCS tables, and determines the configuration information of the set of MCS tables based on the communication application scenario requirements and the air interface wireless channel information. 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. Among them, the communication application scenarios include but are not limited to: eMBB scenarios, URLLC scenarios, and mMTC scenarios.

[0124] The first AI node uses the deep neural network paradigm to model the mapping relationship. Deep neural networks include feedforward neural networks, convolutional neural networks, and recurrent neural networks. A deep neural network consists of an input layer, an output layer, and several hidden layers (N greater than or equal to 1). The input layer, output layer, and each hidden layer each consist of one or more neuron nodes.

[0125] The first AI node processes the communication application scenario and air interface wireless channel information into a D-dimensional vector, where D is greater than or equal to 1. This vector is input to the input layer, passes through N hidden layers, and then to 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.

[0126] The second AI node of the wireless device encodes downlink air interface wireless channel information, including CSI, an air interface channel estimation matrix, eigenvalues ​​and eigenvectors of the air interface channel estimation matrix, singular values, left singular matrix, and right singular matrix of the air interface channel estimation matrix, and transmits the encoded information to the first AI node of the wireless network node. The first AI node maps the encoded information to a set of MCS tables. The second AI node of the wireless device encodes sidelink air interface wireless channel information, including CSI, an air interface channel estimation matrix, eigenvalues ​​and eigenvectors of the air interface channel estimation matrix, singular values, left singular matrix, and right singular matrix of the air interface channel estimation matrix, and transmits the encoded information to the first AI node of the wireless network node. The first AI node maps the encoded information to a set of MCS tables.

[0127] Among them, the second AI node uses the deep neural network paradigm to encode air interface wireless channel information.
