[0037] Modulation and Modulation Constellation Diagram

[0038] Modulation is a crucial process in communication systems, involving the conversion of information signals (such as audio, video, or data) into a form suitable for transmission over communication media (such as radio waves, optical fibers, or wires). In the field of digital communications, a modulation constellation diagram is a pattern representing digital signals on a complex plane (or multiple planes), used to visually represent signals and the relationships between them.

[0039] Currently, there are various types of modulation constellation diagrams, with common modulation schemes including QPSK, 16QAM, 64QAM, 256QAM, and 1024QAM. For example, as shown in Figure 2A, for QPSK, each symbol contains 2 bits, resulting in 4 modulation constellation points (also known as constellation points). As shown in Figure 2B, for 16QAM, each symbol contains 4 bits, resulting in 16 modulation constellation points. As shown in Figure 2C, for 64QAM, each symbol contains 6 bits, resulting in 64 modulation constellation points.

[0040] These different types of modulation constellation diagrams are suitable for different transmission rates and bandwidth requirements. By increasing the number of bits per symbol, data transmission efficiency can be improved, but inter-symbol interference and bit error rate will also increase.

[0041] Wireless communication and artificial intelligence

[0042] In recent years, research in artificial intelligence (AI), represented by neural networks, has achieved significant results in many fields and will play a vital role in people's production and daily lives for a long time to come. A neural network can be understood as a computational model composed of multiple interconnected neuron nodes. The connections between nodes can represent weighted values ​​from the input signal to the output signal, commonly referred to as parameters. Each node performs a weighted summation of different input signals and outputs the result through a specific activation function.

[0043] Neurons can implement nonlinear mappings using activation functions, where the input to the neuron can be denoted as A, and each dimension of the input as a. j The corresponding parameter is denoted as w. j Together with summation units (SUs), they enhance or weaken the input. Furthermore, the output of the SU can be input to the activation function f to obtain the output t, where j takes values ​​of 1, 2, ..., n.

[0044] Common neural networks include convolutional neural networks (CNN), recurrent neural networks (RNN), and deep neural networks (DNN).

[0045] The following description, in conjunction with Figure 3, introduces the neural network applicable to the embodiments of this application. The neural network shown in Figure 3 can be divided into three categories according to the position of different layers: input layer 310, hidden layer 320, and output layer 330. Generally, the first layer is the input layer 310, the last layer is the output layer 330, and the intermediate layers between the first and last layers are all hidden layers 320.

[0046] The input layer 310 is used to input data, which may be, for example, a received signal received by a receiver. The hidden layer 320 is used to process the input data, for example, to decompress the received signal. The output layer 330 is used to output the processed output data, for example, to output the decompressed signal.

[0047] As shown in Figure 3, the neural network consists of multiple layers, each containing multiple neurons. The neurons between layers can be fully connected or partially connected. For connected neurons, the output of a neuron in the previous layer can serve as the input of a neuron in the next layer.

[0048] With the continuous development of neural network research, deep learning algorithms for neural networks have been proposed in recent years. These algorithms incorporate numerous hidden layers, allowing for feature learning through layer-by-layer training of multi-hidden-layer neural networks. This significantly enhances the learning and processing capabilities of neural networks and has led to their widespread application in pattern recognition, signal processing, optimization, and anomaly detection. Figures 4A to 4C illustrate modulation and demodulation operations using a neural network model. Referring to Figure 4A, the AI ​​modulation and demodulation models can be deployed at the encoding and decoding ends respectively. The encoding end inputs the original channel data into the AI ​​modulation to obtain modulated data; correspondingly, the receiving end demodulates the modulated data using AI to obtain the desired output.

[0049] As shown in Figure 4B, the AI ​​modulation model is deployed at the encoding end in a single-end configuration. The encoding end inputs the raw channel data into the AI ​​modulation to obtain modulated data, and correspondingly, the receiving end demodulates the modulated data using conventional methods to obtain the output.

[0050] As shown in Figure 4C, the AI ​​demodulation model is deployed at the encoding end in a single-end configuration. The encoding end inputs the original channel data into conventional modulation to obtain modulated data, and correspondingly, the receiving end demodulates the modulated data using AI to obtain the desired output.

[0051] In traditional modulation and demodulation processes, the modulation / demodulation methods used between the signal transmitter and receiver are usually predefined or preconfigured. This predefined modulation / demodulation scheme may limit signal transmission efficiency.

[0052] Therefore, in response to the above-mentioned solution, this application embodiment proposes that the first device can send first information to the second device to indicate the first information associated with the first modulation method. In this way, the first device and the second device can flexibly adjust the modulation method used, which helps to improve signal transmission efficiency. The wireless communication method of this application embodiment is described below with reference to FIG5. The method shown in FIG5 includes step S510.

[0053] In step S510, the first device sends first information to the second device, wherein the first device can be the signal modulator described above, and correspondingly, the second device can be the signal demodulator described above. Of course, in the embodiments of this application, the first device can be the signal demodulator described above, and correspondingly, the second device can be the signal modulator described above.

[0054] For example, the first device can be a terminal device, and correspondingly, the second device can be a network device. Alternatively, the first device can be a network device, and correspondingly, the second device can be a terminal device. Yet another example is that both the first and second devices can be terminal devices.

[0055] In some scenarios, the first modulation scheme can correspond to the first modulation constellation diagram; therefore, associating the first information with the first modulation scheme can be replaced by associating the first information with the first modulation constellation diagram. In other scenarios, the first modulation scheme can correspond to the first constellation point; therefore, associating the first information with the first modulation scheme can be replaced by associating the first information with the first modulation constellation point. That is to say, the first information is associated with one or more of the following: the first modulation scheme; the first modulation constellation diagram; and the first modulation constellation point.

[0056] As mentioned earlier, due to the introduction of new modulation / demodulation methods (e.g., modulation / demodulation based on AI / ML models), the modulation constellation diagram is more flexible (usually irregular) than traditional modulation methods, making it difficult to continue using the traditional modulation constellation point description method.

[0057] Therefore, to address the aforementioned issues, this application introduces a first parameter to describe the first modulation constellation diagram, or in other words, the first parameter to describe the first modulation scheme, or the first parameter to describe the first modulation constellation points. This facilitates consensus between the modulator and demodulator of the signal based on the currently used modulation constellation diagram, thereby improving signal transmission efficiency.

[0058] In some implementations, the first modulation scheme corresponds to Q modulation constellation points, and / or the first modulation constellation diagram includes Q modulation constellation points, and / or the first modulation constellation points are determined based on Q modulation constellation points, where Q is an integer greater than or equal to 1. The following description is based on Q modulation constellation points.

[0059] In some implementations, the Q modulation constellation points can be uniformly or non-uniformly distributed on one or more circles, where the circles can be, for example, circles in a complex plane. This will be described below with reference to Figure 6.

[0060] In some implementations, Q modulation constellation points can correspond to one transport stream, or Q modulation constellation points can correspond to multiple different transport streams.

[0061] In some implementations, the Q modulation points corresponding to one transport stream can be distributed on a single circle (e.g., a circle in the complex plane). In other implementations, the Q modulation points corresponding to one transport stream can be distributed on different circles (e.g., circles in the complex plane).

[0062] In some implementations, the Q modulation points corresponding to different transport streams can be distributed on a single circle (e.g., a circle in the complex plane). In other implementations, the Q modulation points corresponding to different transport streams can be distributed on different circles (e.g., circles in the complex plane).

[0063] In some implementations, the modulation constellation point can be described using amplitude (A) and / or angle (w). For example, the modulation constellation point can be represented as A×e. jw Where A represents the amplitude value of the modulation constellation point (or can be described as the radius on the complex plane), and w represents the angle value of the modulation constellation point (or can be described as the phase value).

[0064] The arrangement of the Q modulation constellation points in the embodiments of this application has been described above. The arrangement of the constellation set in the embodiments of this application will be described below.

[0065] In some implementations, Q modulation constellation points belong to a group of M constellation points, where M is an integer greater than or equal to 1, and the value of M is less than or equal to Q.

[0066] In some implementations, a constellation point group may include K modulation constellation points, where K is a positive integer greater than or equal to 1, and the value of K is less than or equal to Q.

[0067] In some implementations, the number of modulation constellation points contained in different constellation point groups among the M constellation point groups can be the same or different. For example, the first constellation point group among the M constellation point groups contains 8 modulation constellation points, and the second constellation point group among the M constellation point groups contains 8 modulation constellation points. Another example is that the first constellation point group among the M constellation point groups contains K1 modulation constellation points, and the second constellation point group among the M constellation point groups contains K2 modulation constellation points, where K1 and K2 are different positive integers. Yet another example is that 64 modulation constellation points are non-uniformly distributed on a circle with amplitude (radius) A in the complex plane, and these 64 modulation constellation points belong to 12 constellation point groups. Four of these groups each contain 8 modulation constellation points, and the remaining eight groups each contain 4 modulation constellation points.

[0068] In some implementations, a constellation point group may include multiple modulation constellation points, with a second interval between two of the multiple modulation constellation points.

[0069] In this application embodiment, the implementation method of the second interval is not limited. In some implementations, the second interval may include one or more of the following: angular interval; phase interval; and distance interval (e.g., Euclidean distance interval). For example, the second interval is an angular interval Y, where the value of Y ranges from 0 to 2π. Another example is a phase interval Y, where the value of Y ranges from π / D, where D is a positive number or a positive integer. For example, the value of D can be 2, 3, 4, 6, 8, 9, 12, 15, 16, 18, 24, 32, 36, 48, or 64. For another example, the second interval is a distance interval Y, where the value of Y is a positive number.

[0070] In this embodiment, the two modulation constellation points associated with the second interval are not limited. In some implementations, the two modulation constellation points may include a modulation constellation point in a constellation point group and a reference modulation constellation point. The reference modulation constellation point may be one or more of the following: the first modulation constellation point in the constellation point group, the last modulation constellation point in the constellation point group, or an intermediate modulation constellation point in the constellation point group. Of course, in this embodiment, the reference modulation constellation point may also be other agreed-upon modulation constellation points. In this case, the reference modulation constellation point may be a modulation constellation point within the constellation point group or a modulation constellation point not belonging to the constellation point group.

[0071] In the embodiments of this application, the first modulation constellation point, the last modulation constellation point, and the intermediate modulation constellation points in the constellation point group can correspond to the order of the modulation constellation points in the complex plane. The order in the complex plane can be determined, for example, based on the order of the real parts and / or the order of the imaginary parts in the complex plane.

[0072] For example, the modulation constellation points in a constellation point group can be sorted in ascending order of their real parts and imaginary parts. Correspondingly, the first modulation constellation point in the constellation point group can be the one with the smallest real and imaginary parts. The last modulation constellation point in the constellation point group can be the one with the largest real and imaginary parts. Furthermore, the other modulation constellation points in the constellation point group besides the first and last ones are called intermediate modulation constellation points.

[0073] For example, the modulation constellation points in a constellation point group can be sorted according to their real parts in ascending order and their imaginary parts in descending order. Correspondingly, the first modulation constellation point in the constellation point group can be the one with the smallest real part and the largest imaginary part. The last modulation constellation point in the constellation point group can be the one with the largest real part and the smallest imaginary part. Furthermore, the other modulation constellation points in the constellation point group besides the first and last modulation constellation points are called intermediate modulation constellation points.

[0074] For example, the modulation constellation points in a constellation point group can be sorted according to their real parts in descending order and their imaginary parts in ascending order. Correspondingly, the first modulation constellation point in the constellation point group can be the one with the largest real part and the smallest imaginary part. The last modulation constellation point in the constellation point group can be the one with the smallest real part and the largest imaginary part. Furthermore, the other modulation constellation points in the constellation point group besides the first and last modulation constellation points are called intermediate modulation constellation points.

[0075] For example, the modulation constellation points in a constellation point group can be sorted according to their real parts in descending order and their imaginary parts in descending order. Correspondingly, the first modulation constellation point in the constellation point group can be the one with the largest real and imaginary parts. The last modulation constellation point in the constellation point group can be the one with the smallest real and imaginary parts. Furthermore, the other modulation constellation points in the constellation point group besides the first and last ones are called intermediate modulation constellation points.

[0076] Of course, in the embodiments of this application, the order of the modulation constellation points in the complex plane is not limited. For example, the order of the modulation constellation points in the complex plane can also be determined based on the order of the real parts first and then the order of the imaginary parts, or the order of the imaginary parts first and then the order of the real parts.

[0077] In some implementations, the second interval between two constellation points in different constellation groups within the M constellation point groups can be the same or different. For example, the second interval between modulation constellation points in the first constellation point group of the M constellation point groups is Y1, and the interval between modulation constellation points in the second constellation point group of the M constellation point groups is Y2, where Y1 and Y2 have different values.

[0078] The preceding text describes the second interval between two constellation points within a constellation point group in the embodiments of this application, whereby the second interval is also referred to as the intra-group interval. The following text describes the first interval between constellation point groups in the embodiments of this application, whereby the first interval is also referred to as the inter-group interval, or the constellation group interval.

[0079] In some implementations, the first interval may be the interval between specific modulation constellation points in two constellation point groups. In the embodiments of this application, the implementation of the first interval is not limited. In some implementations, the first interval may include one or more of the following: angular interval; phase interval; distance interval (e.g., Euclidean distance interval).

[0080] For example, the first interval is an angular interval X, where the value of X ranges from 0 to 2π. Another example is a phase interval X, where the value of X ranges from π / D, where D is a positive number or a positive integer. For example, the value of D can be 2, 3, 4, 6, 8, 9, 12, 15, 16, 18, 24, 32, 36, 48, or 64. Yet another example is a distance interval X, where the value of X is a positive number.

[0081] In the embodiments of this application, the two constellation point groups associated with the first interval are not limited. In some implementations, the two constellation point groups can be two adjacent constellation point groups. In other implementations, the two constellation point groups can be a constellation point group and a reference constellation point group, wherein the reference constellation point group can be one or more of the following: the first constellation point group on the complex plane, the last constellation point group on the complex plane, and an intermediate constellation point group on the complex plane.

[0082] In the embodiments of this application, the specific modulation constellation point in the two constellation groups associated with the first interval is not limited. In some implementations, the specific modulation constellation point can be one or more of the following: the first modulation constellation point in the constellation point group, the last modulation constellation point in the constellation point group, and the middle modulation constellation point in the constellation point group.

[0083] In the embodiments of this application, the first modulation constellation point, the last modulation constellation point, and the intermediate modulation constellation points in the constellation point group can correspond to the order of the modulation constellation points in the complex plane. The order in the complex plane can be determined, for example, based on the order of the real parts and / or the order of the imaginary parts in the complex plane. For related information, please refer to the above.

[0084] In some implementations, the first constellation group among the M constellation point groups corresponds to multiple different transport streams, or a certain constellation point group among the M constellation point groups corresponds to multiple different transport streams. For example, the first constellation point group can correspond to 2 different transport streams. As another example, when M is 4, the 4 constellation point groups can correspond to 2 different transport streams.

[0085] In some implementations, the transport streams corresponding to different constellation point groups within the M constellation point groups can be the same or different. For example, two different constellation point groups can correspond to two different transport streams. As another example, four different constellation point groups can correspond to four different transport streams.

[0086] In some implementations, the constellation point amplitudes corresponding to the same transport flow in M ​​constellation point groups may be the same or different. The constellation point amplitude can be represented by the radius of a circle in the complex plane. For example, if the constellation point amplitudes corresponding to the same transport flow in M ​​constellation point groups are the same, it can be understood that the corresponding radii of the constellation point groups corresponding to the same transport flow in the M constellation point groups are the same in the complex plane. Conversely, if the constellation point amplitudes corresponding to the same transport flow in M ​​constellation point groups are different, it can be understood that the corresponding radii of the constellation point groups corresponding to the same transport flow in the M constellation point groups are different in the complex plane.

[0087] In some implementations, the constellation point amplitudes corresponding to different transport streams in the M constellation point groups may be the same or different. The constellation point amplitude can be represented by the radius of a circle in the complex plane. For example, if the constellation point amplitudes corresponding to different transport streams in the M constellation point groups are the same, it can be understood that the corresponding radii of the constellation point groups corresponding to different transport streams in the M constellation point groups are the same in the complex plane. Conversely, if the constellation point amplitudes corresponding to different transport streams in the M constellation point groups are different, it can be understood that the corresponding radii of the constellation point groups corresponding to different transport streams in the M constellation point groups are different in the complex plane.

[0088] In some implementations, some or all of the M constellation point groups correspond to constellation point amplitudes that are identical. These amplitudes can be represented by the radii of circles in the complex plane. For example, if some constellation point groups in the M constellation point groups have identical amplitudes, it can be understood that these groups have identical radii in the complex plane. Similarly, if all constellation point groups in the M constellation point groups have identical amplitudes, it can be understood that these groups have identical radii in the complex plane.

[0089] In some implementations, the amplitudes of constellation points differ among different constellation point groups within the M constellation point groups. These amplitudes can be represented by the radius of a circle in the complex plane. For example, the amplitude of the first constellation point group within the M constellation point groups might be A1, and the amplitude of the second constellation point group might be A2, where A1 and A2 are positive numbers with different values.

[0090] For ease of understanding, the arrangement of the Q modulation constellation points in this embodiment is described below with reference to Figure 6. Referring to Figure 6, assume that Q is 16, and that the 16 modulation constellation points belong to 8 constellation point groups, with each group comprising 2 modulation constellation points. The 16 modulation constellation points are non-uniformly distributed on a circle with an amplitude (i.e., radius on the complex plane) of radius A. The second interval Y1 between modulation constellation points within a constellation point group is π / 32, and the first interval X1 between two constellation point groups is π / 8.

[0091] For example, suppose Q has 256 modulation constellation points, and these 256 points belong to 16 constellation point groups, each group containing 16 points. Accordingly, the 256 modulation constellation points are non-uniformly distributed on a circle with amplitude (radius) A in the complex plane. The second interval Y2 angle between modulation constellation points within a constellation point group is π / 512, and the first interval X2 angle between two constellation point groups is π / 16.

[0092] The arrangement of constellation point groups in the embodiments of this application has been described above. The arrangement of constellation point groups in the embodiments of this application will be described below. A constellation point group may include one or more constellation point groups. For an introduction to constellation point groups, please refer to the above.

[0093] In some implementations, Q modulation constellation points belong to a group of N constellation points, where N is an integer greater than or equal to 1, and the value of N is less than or equal to Q.

[0094] In some implementations, the number of constellation point groups contained in different constellation point groups among the N constellation point groups can be the same or different. For example, the first constellation point group among the N constellation point groups contains 8 constellation point groups, the second constellation point group among the N constellation point groups contains 8 constellation point groups, the third constellation point group among the N constellation point groups contains 8 constellation point groups, and the fourth constellation point group among the N constellation point groups contains 1 constellation point group.

[0095] In some implementations, the interval between two constellation point groups in N constellation point groups is the fourth interval.

[0096] In this application embodiment, the implementation method of the fourth interval is not limited. In some implementations, the fourth interval may include one or more of the following: angular interval; phase interval; and distance interval (e.g., Euclidean distance interval). For example, the fourth interval is an angular interval P, where the value of P ranges from 0 to 2π. Another example is a phase interval P, where the value of P ranges from π / D, where D is a positive number or a positive integer. For example, the value of D can be 2, 3, 4, 6, 8, 9, 12, 15, 16, 18, 24, 32, 36, 48, or 64. For example, the fourth interval is a distance interval P, where the value of P is a positive integer. Of course, in this application embodiment, the fourth interval can be the difference between the amplitudes (i.e., the radii in the complex plane) corresponding to the modulation constellation points in two constellation point groups.

[0097] In this embodiment, the two constellation point groups associated with the fourth interval are not limited. In some implementations, the two constellation point groups may include a constellation point group in the modulation constellation diagram and a reference constellation point group, wherein the reference constellation point group may be one or more of the following: the first constellation point group in the modulation constellation diagram, the last constellation point group in the modulation constellation diagram, or an intermediate constellation point group in the modulation constellation diagram.

[0098] In the embodiments of this application, the first constellation point group, the last constellation point group, and the intermediate constellation point group in the modulation constellation diagram can correspond to the order of the constellation point groups in the complex plane. The order in the complex plane can be determined, for example, based on the order of the real part and / or the order of the imaginary part in the complex plane.

[0099] For example, constellation point groups in a modulation constellation diagram can be ordered in ascending order of real parts and ascending order of imaginary parts. Correspondingly, the first constellation point group in the modulation constellation diagram can be the group containing the modulation constellation point with the smallest real and imaginary parts. The last constellation point group in the modulation constellation diagram can be the group containing the modulation constellation point with the largest real and imaginary parts. Furthermore, all other constellation point groups in the modulation constellation diagram besides the first and last constellation point groups are considered intermediate constellation point groups.

[0100] For example, constellation point groups in a modulation constellation diagram can be ordered according to their real parts from smallest to largest and their imaginary parts from largest to smallest. Correspondingly, the first constellation point group in the modulation constellation diagram can be the group containing the modulation constellation point with the smallest real part and the largest imaginary part. The last constellation point group in the modulation constellation diagram can be the group containing the modulation constellation point with the largest real part and the smallest imaginary part. Furthermore, the constellation point groups in the modulation constellation diagram other than the first and last constellation point groups are called intermediate constellation point groups.

[0101] For example, constellation point groups in a modulation constellation diagram can be ordered according to their real parts from largest to smallest and their imaginary parts from smallest to largest. Correspondingly, the first constellation point group in the modulation constellation diagram can be the group containing the modulation constellation point with the largest real part and the smallest imaginary part. The last constellation point group in the modulation constellation diagram can be the group containing the modulation constellation point with the smallest real part and the largest imaginary part. Furthermore, all other constellation point groups in the modulation constellation diagram besides the first and last constellation point groups are considered intermediate constellation point groups.

[0102] For example, constellation point groups in a modulation constellation diagram can be ordered according to both the order of their real parts from largest to smallest and their imaginary parts from largest to smallest. Correspondingly, the first constellation point group in the modulation constellation diagram can be the group containing the modulation constellation point with the largest real and imaginary parts. The last constellation point group in the modulation constellation diagram can be the group containing the modulation constellation point with the smallest real and imaginary parts. Furthermore, all other constellation point groups in the modulation constellation diagram besides the first and last constellation point groups are considered intermediate constellation point groups.

[0103] Of course, in the embodiments of this application, the order of the constellation point groups on the complex plane is not limited. For example, the order of the constellation point groups on the complex plane can also be determined based on the order of the real parts first and then the order of the imaginary parts, or the order of the imaginary parts first and then the order of the real parts.

[0104] In some implementations, the fourth interval between two different constellation point groups in N constellation point groups can be the same or different.

[0105] The fourth interval between constellation point groups in this application embodiment has been introduced above. The third interval between two constellation point groups within a constellation point group in this application embodiment is introduced below. The third interval is also called the inter-group interval or the constellation group interval. It should be noted that the third interval in this application embodiment is similar to the first interval introduced above. For relevant information, please refer to the above text.

[0106] In this embodiment, the two constellation point groups associated with the third interval are not limited. In some implementations, the two constellation point groups can be two adjacent constellation point groups. In other implementations, the two constellation point groups can be a constellation point group and a reference constellation point group, wherein the reference constellation point group can be one or more of the following: the first constellation point group in a constellation point group, the last constellation point group in a constellation point group, or an intermediate constellation point group in a constellation point group.

[0107] In the embodiments of this application, the first constellation point group, the last constellation point group, and the intermediate constellation point group in the constellation point group can correspond to the order of the constellation point group in the complex plane. The order in the complex plane can be determined, for example, based on the order of the real part and / or the order of the imaginary part in the complex plane.

[0108] For example, constellation point groups in a constellation point group can be sorted in ascending order of real parts and ascending order of imaginary parts. Correspondingly, the first constellation point group in the constellation point group can be the constellation point group containing the modulation constellation point with the smallest real and imaginary parts. The last constellation point group in the constellation point group can be the constellation point group containing the modulation constellation point with the largest real and imaginary parts. Furthermore, the constellation point groups in the constellation point group other than the first and last constellation point groups are called intermediate constellation point groups.

[0109] For example, constellation point groups in a constellation point group can be sorted according to their real parts in ascending order and their imaginary parts in descending order. Correspondingly, the first constellation point group in the constellation point group can be the constellation point group containing the modulation constellation point with the smallest real part and the largest imaginary part. The last constellation point group in the constellation point group can be the constellation point group containing the modulation constellation point with the largest real part and the smallest imaginary part. Furthermore, the constellation point groups in the constellation point group other than the first and last constellation point groups are called intermediate constellation point groups.

[0110] For example, constellation point groups in a constellation point group can be sorted according to their real parts in descending order and their imaginary parts in ascending order. Correspondingly, the first constellation point group in the constellation point group can be the constellation point group containing the modulation constellation point with the largest real part and the smallest imaginary part. The last constellation point group in the constellation point group can be the constellation point group containing the modulation constellation point with the smallest real part and the largest imaginary part. Furthermore, the constellation point groups in the constellation point group other than the first and last constellation point groups are called intermediate constellation point groups.

[0111] For example, constellation point groups in a constellation point group can be sorted according to their real parts in descending order and their imaginary parts in descending order. Correspondingly, the first constellation point group in the constellation point group can be the constellation point group containing the modulation constellation point with the largest real and imaginary parts. The last constellation point group in the constellation point group can be the constellation point group containing the modulation constellation point with the smallest real and imaginary parts. Furthermore, the constellation point groups in the constellation point group other than the first and last constellation point groups are called intermediate constellation point groups.

[0112] Of course, in the embodiments of this application, the order of the constellation point groups on the complex plane is not limited. For example, the order of the constellation point groups on the complex plane can also be determined based on the order of the real parts first and then the order of the imaginary parts, or the order of the imaginary parts first and then the order of the real parts.

[0113] In some implementations, the third intervals corresponding to different constellation point groups within N constellation point groups can be the same or different. For example, the N constellation point groups include a first constellation point group and a second constellation point group. The third interval between constellation point groups within the first constellation point group is X1, and the third interval between constellation point groups within the second constellation point group is X2, where X1 and X2 are different. Another example is that the N constellation point groups include a third constellation point group and a fourth constellation point group. The third interval between constellation point groups within the third constellation point group is X3, and the third interval between constellation point groups within the fourth constellation point group is also X3. Yet another example is that the third interval Y4 between constellation point groups within the first constellation point group is π / 32, and the third interval Y5 between constellation point groups within the second constellation point group is π / 4. Yet another example is that the third interval Y6 between constellation point groups within the third constellation point group is π / 16, and the third interval Y6 between constellation point groups within the fourth constellation point group is also π / 16.

[0114] In some implementations, if multiple constellation point groups are mapped onto a circle of the same amplitude (i.e., radius on the complex plane), the second interval between modulation constellation points within constellation point groups of different constellation point groups can be different. For example, if the first constellation point group and the second constellation point group are located on a circle of the same amplitude, the second interval Y7 between modulation constellation points within the constellation point group of the first constellation point group is π / 8, and the second interval Y8 between modulation constellation points within the constellation point group of the second constellation point group is π / 32. Of course, in the embodiments of this application, if multiple constellation point groups are mapped onto a circle of the same amplitude (i.e., radius on the complex plane), the second interval between modulation constellation points within constellation point groups of different constellation point groups can be the same.

[0115] In some implementations, the second interval between modulation constellation points in different constellation point groups within the same constellation point group can be the same or different. For example, the second interval between modulation constellation points in the first constellation point group of the first constellation point group is Y9, and the second interval between modulation constellation points in the second constellation point group of the first constellation point group is Y10, where Y9 and Y10 are different positive numbers.

[0116] In some implementations, the first constellation point group among N constellation point groups corresponds to multiple different transport streams, or a certain constellation point group among N constellation point groups corresponds to multiple different transport streams. For example, the first constellation point group can correspond to 2 different transport streams. As another example, when N is 4, 4 constellation point groups can correspond to 2 different transport streams.

[0117] In some implementations, the transport streams corresponding to different constellation point groups among N constellation point groups can be the same or different. For example, two different constellation point groups can correspond to two different transport streams. Another example is that four different constellation point groups can correspond to four different transport streams. Yet another example is that four different constellation point groups can correspond to a single, identical transport stream.

[0118] In some implementations, the constellation point amplitudes corresponding to the same transport stream within N constellation point groups may be the same or different. For example, if the constellation point amplitudes corresponding to the same transport stream within N constellation point groups are the same, it can be understood that the radii corresponding to the same transport stream within N constellation point groups in the complex plane are the same. Conversely, if the constellation point amplitudes corresponding to the same transport stream within N constellation point groups are different, it can be understood that the radii corresponding to the same transport stream within N constellation point groups in the complex plane are different.

[0119] In some implementations, the constellation point amplitudes corresponding to different transport streams within N constellation point groups may be the same or different. For example, if the constellation point amplitudes corresponding to different transport streams within N constellation point groups are the same, it can be understood as the radii corresponding to the constellation point groups corresponding to different transport streams within the N constellation point groups on the complex plane being the same. Conversely, if the constellation point amplitudes corresponding to different transport streams within N constellation point groups are different, it can be understood as the radii corresponding to the constellation point groups corresponding to different transport streams within the N constellation point groups on the complex plane being different.

[0120] In some implementations, some or all of the constellation point groups in N constellation point groups have the same amplitude. For example, if some constellation point groups in N constellation point groups have the same amplitude, it can be understood as if some constellation point groups have the same radius on the complex plane. Similarly, if all constellation point groups in N constellation point groups have the same amplitude, it can be understood as if all constellation point groups have the same radius on the complex plane. Furthermore, different constellation point groups in N constellation point groups can lie on circles with different amplitudes (i.e., the radius of the complex plane), and the N constellation point groups can be ordered either from largest to smallest amplitude or from smallest to largest amplitude.

[0121] For ease of understanding, the arrangement of the Q modulation constellation points in another embodiment of this application is described below with reference to Figure 7. Referring to Figure 7, assume that the value of Q is 64, and that the 64 modulation constellation points belong to four constellation point groups. These four constellation point groups, ordered from smallest to largest real part, are constellation point group 1, constellation point group 2, constellation point group 3, and constellation point group 4. The complex plane radii corresponding to different constellation point groups within the four constellation point groups are different.

[0122] Constellation point group 1 includes 8 constellation point groups, each constellation point group includes 4 modulation constellation points, wherein the third interval between two adjacent constellation point groups in the 8 constellation point groups is a1.

[0123] Constellation point group 2 includes 8 constellation point groups, and each constellation point group includes 2 modulation constellation points. Among them, the third interval between any two adjacent constellation point groups is a2.

[0124] Constellation point group 3 includes 8 constellation point groups. Four of these groups each contain 2 modulation constellation points, and the remaining four groups each contain 1 modulation constellation point. The third interval between any two adjacent constellation point groups is a3.

[0125] Constellation point group 4 includes 4 constellation point groups, and each constellation point group includes 1 modulation constellation point. Among them, the third interval between any two adjacent constellation point groups in the 8 constellation point groups is a4.

[0126] The arrangement of the Q modulation constellation points in the embodiments of this application has been described above with reference to Figures 6 and 7. In some implementations, the topological pattern (or arrangement) of the Q modulation constellation points is honeycomb-shaped. For example, the pattern of the Q modulation constellation points on the complex plane is honeycomb-shaped.

[0127] In some implementations, the distance between any two adjacent modulation constellation points in the Q modulation constellation points, which are arranged in a honeycomb pattern, is equal. The distance between modulation constellation points can be found in the previous section on the second interval. For example, as shown in Figure 8A, each of the Q modulation constellation points has three adjacent modulation constellation points. The first interval between adjacent modulation constellation points (in the complex plane) is the spacing A, and the angular difference between adjacent modulation constellation points is 120 degrees, or in other words, the phase difference between adjacent modulation constellation points is 2π / 3.

[0128] For example, as shown in Figure 8B, each of the Q modulation constellation points has 6 adjacent modulation constellation points. The first interval between adjacent modulation constellation points (on the complex plane) is the spacing A, and the angle between adjacent modulation constellation points differs by 60 degrees, or in other words, the phase difference between adjacent modulation constellation points is π / 3. It should be understood that if an adjacent modulation constellation point is located at the origin, the modulation constellation point located at the origin is discarded. In this case, some modulation constellation points have 5 adjacent constellation points.

[0129] In some implementations, the Q modulation constellation points, which are arranged in a honeycomb pattern, are not located at the origin of the coordinate system. The origin of the coordinate system can be, for example, the origin of the complex plane, as shown in Figure 8B.

[0130] In some implementations, the Q modulation constellation points present a honeycomb pattern, comprising multiple sets of constellation points, each set of constellation points being hexagonal, and each set of constellation points being located at the vertex of the hexagon, as shown in Figure 8C.

[0131] In some implementations, the modulation constellation points shown in Figure 8C can be understood as a subset of the honeycomb-shaped modulation constellation points (e.g., Figure 8B). That is, the arrangement of modulation constellation points shown in Figure 8C is obtained by removing the modulation constellation points located at the center of the hexagon in the honeycomb-shaped modulation constellation points (e.g., Figure 8B).

[0132] In some implementations, the Q modulation constellation points are the input modulation constellation points of a first AI / ML model, which is used for signal modulation; and / or the Q modulation constellation points are the output modulation constellation points of a second AI / ML model, which is used for signal demodulation.

[0133] The arrangement of the Q modulation constellation points in the embodiments of this application has been described above. The following section describes the arrangement scheme described above using a first parameter in the embodiments of this application. It should be noted that the following description only focuses on the content included in the first parameter. The relevant terminology and schemes for the arrangement of the modulation constellation points included in the first parameter can be found in the above description and will not be repeated here for brevity. Furthermore, in the embodiments of this application, one or more of the aforementioned arrangements of the Q modulation constellation points (or modulation constellation point characteristics) can be used as the first parameter.

[0134] In some implementations, the first information is used to determine the first parameter, which is associated with one or more of the following: a first modulation scheme; a first modulation constellation diagram; and a first modulation constellation point.

[0135] In some implementations, the first parameter includes one or more of the following: the number of Q modulation constellation points; the topological pattern of the Q modulation constellation points; the arrangement of the Q modulation constellation points in the coordinate system; the second parameter associated with the M constellation point groups to which the Q modulation constellation points belong; and the third parameter associated with the N constellation point groups to which the Q modulation constellation points belong.

[0136] In some implementations, the topology pattern of the Q modulation constellation points is honeycomb-shaped, as can be seen from the previous description.

[0137] In some implementations, the Q modulation constellation points are arranged in the coordinate system either uniformly or non-uniformly on the circumference of the complex plane.

[0138] In some implementations, the second parameter includes one or more of the following: the transport stream corresponding to each constellation point group in the M constellation point groups; the constellation point amplitude corresponding to each constellation point group in the M constellation point groups; the number of constellation points contained in each constellation point group in the M constellation point groups; the first interval between two constellation point groups in the M constellation point groups; and the second interval between two constellation points within each constellation point group in the M constellation point groups.

[0139] In some implementations, the third parameter includes one or more of the following: the transport stream corresponding to each constellation point group in the N constellation point groups; the constellation point amplitude corresponding to each constellation point group in the N constellation point groups; the number of constellation point groups contained in each constellation point group in the N constellation point groups; the third interval between two constellation point groups within each constellation point group in the N constellation point groups; and the fourth interval between two constellation points within each constellation point group in the N constellation point groups.

[0140] The first parameter in the embodiments of this application has been introduced above, and the first information in the embodiments of this application will be introduced below.

[0141] In some implementations, the first information is used to indicate one or more of the following: the first information is used to indicate or transmit a first modulation constellation diagram; the first information is used to indicate a first modulation scheme; the first information is used to indicate or transmit an AI / ML model; the first information is used to indicate Q modulation constellation points supported by the first device.

[0142] In some implementations, the first information is used to indicate or transmit a first modulation constellation diagram. Taking the first information as indicating a first modulation constellation diagram as an example, the first information may carry an identifier of the first modulation constellation diagram, and accordingly, the first information indicates the first modulation constellation diagram through this identifier.

[0143] In this embodiment of the application, the first modulation constellation diagram may be the modulation constellation diagram currently used by the first device, or the first modulation constellation diagram may be the modulation constellation diagram to be used.

[0144] In some implementations, the first information is used to indicate a first modulation scheme so that the second device can determine a matching demodulation scheme based on the first modulation scheme.

[0145] In this application embodiment, the implementation method of the first information indicating the first modulation method is not limited. In some implementations, the first information may carry an identifier associated with the first modulation method to indicate the first modulation method. The identifier associated with the first modulation method may include one or more of the following: a model function ID corresponding to the first modulation method, a model ID corresponding to the first modulation method, and a condition ID corresponding to the first modulation method, wherein the condition ID is used to indicate the wireless communication conditions under which the first modulation method is applied (e.g., interference conditions in the wireless communication environment, the moving speed of the first device in the wireless communication environment, the moving speed of the second device in the wireless communication environment, etc.).

[0146] In some implementations, the first information is used to indicate or transmit an AI / ML model, wherein the AI / ML model is associated with one or more of the following: a first modulation scheme, a first modulation constellation diagram, and first modulation constellation points. This helps the second device determine the arrangement characteristics of the modulation constellation points and / or determine the AI / ML model used for demodulation. For example, if the AI / ML model indicated by the first information is used for modulation, the second device can accordingly determine the arrangement characteristics of the modulation constellation points based on the first information. As another example, if the AI / ML model indicated by the first information is used for demodulation, the second device can accordingly determine the AI / ML model used for demodulation based on the first information.

[0147] In this application embodiment, the implementation method of the first information indicating the AI / ML model is not limited. In some implementations, the first information may carry an identifier associated with the AI / ML model to indicate the AI / ML model. The identifier associated with the AI / ML model may include one or more of the following: the model function ID corresponding to the AI / ML model, the model ID corresponding to the AI / ML model, and the condition ID corresponding to the AI / ML model, wherein the condition ID is used to indicate the wireless communication conditions for which the AI / ML model is applied (e.g., interference conditions in the wireless communication environment, the moving speed of the first device in the wireless communication environment, the moving speed of the second device in the wireless communication environment, etc.).

[0148] In some implementations, the first information is used to indicate the Q modulation constellation points supported by the first device. In this application embodiment, the implementation method of the first information indicating the Q modulation constellation points supported by the first device is not limited. In some implementations, the first information may carry an identifier associated with the Q modulation constellation points supported by the first device to indicate the Q modulation constellation points supported by the first device. The identifier associated with the Q modulation constellation points may include one or more of the following: a model function ID corresponding to the Q modulation constellation points, a model ID corresponding to the Q modulation constellation points, and a condition ID corresponding to the Q modulation constellation points, wherein the condition ID is used to indicate the wireless communication conditions for which the AI / ML model is applied (e.g., interference conditions in the wireless communication environment, the moving speed of the first device in the wireless communication environment, the moving speed of the second device in the wireless communication environment, etc.).

[0149] In other implementations, the first information may carry constraints associated with the Q modulation constellation points supported by the first device, indicating the Q modulation constellation points supported by the first device, wherein the constraints are used to select the Q modulation constellation points supported by the first device. For example, the constraints may refer to the minimum interval between two modulation constellation points supported by the first device.

[0150] In some implementations, the Q modulation constellation points supported by the first device can be indicated by constellation point groups, constellation point clusters, or constellation point features (e.g., the first parameters described above for describing the Q constellation points).

[0151] In some implementations, the Q modulation constellation points supported by the first device are associated with the radio frequency (RF) capabilities of the first device. For example, the RF capability limitations of the first device affect the minimum spacing between two modulation constellation points supported by the first device.

[0152] In this application embodiment, the transmission method of the first information is not limited. In some implementations, if the first information is sent from the network device to the terminal device, the first information may be carried in one or more of the following: broadcast messages (e.g., master information block (MIB), system information block 1 (SIB1), SIBx); radio resource control (RRC) messages; medium access control element (MAC CE); downlink control information (DCI); downlink messages in the random access process (e.g., MsgB, Msg2, Msg4); physical downlink control channel (PDCCH); physical downlink shared channel (PDSCH); AI / ML dedicated downlink channel; network-side capability indication.

[0153] In other implementations, if the first information is sent from the terminal device to the network device, the first information may be carried in one or more of the following: RRC message; uplink control information (UCI); uplink messages during random access (e.g., MsgA and / or Msg3); physical uplink control channel (PUCCH); physical uplink shared channel (PUSCH); AI / ML dedicated uplink channel; UE capability reporting.

The apparatus embodiments of this application will be described in detail below with reference to Figures 9 to 11. It should be understood that the descriptions of the method embodiments correspond to the descriptions of the apparatus embodiments; therefore, any parts not described in detail can be referred to the foregoing method embodiments.
