[0041] The technical solutions in this application will be described below in conjunction with the accompanying drawings. To facilitate understanding of this application, the following first introduces the terms and communication processes involved in the embodiments of this application in conjunction with Figures 1 to 9.
[0042] 1. Signal Transmission Process in Wireless Communication Systems
[0043] Figure 1 is a flow chart of signal transmission in a wireless communication system to which embodiments of the present application are applicable. As shown in Figure 1 , the signal transmission process in the wireless communication system can be roughly divided into the various signal processing processes S111 to S118 shown in Figure 1 . Some or all of the signal processing processes shown in Figure 1 can be implemented using a separate AI model.
[0044] In the channel coding process S111, the transmitter performs channel coding on the information to be transmitted to obtain a coded code stream. The information to be transmitted may be in the form of a bit stream.
[0045] In the modulation process S112 , the code stream is modulated into modulation symbols.
[0046] In the pilot insertion process S113, pilot symbols are inserted into the modulation symbols to form a signal to be transmitted, wherein the pilot symbols can be used by a receiver to perform channel estimation and symbol detection.
[0047] In the transmission signal S114, the above signal is carried on the channel and transmitted to the receiver. In the process of transmitting the signal through the channel, noise is usually superimposed.
[0048] In the channel estimation process S115, the receiver can perform channel estimation based on the reference signal to obtain channel state information (CSI), and feed the CSI back to the transmitter through a feedback link for the transmitter to adjust channel coding, modulation, precoding, etc.
[0049] In the symbol detection process S116, symbol detection is performed on the received modulation symbols to obtain a detection result.
[0050] In the demodulation process S117, the received modulation symbols are demodulated based on the detection result to obtain a code stream.
[0051] In the channel decoding process S118, the code stream is decoded to obtain restored information, wherein the restored information may be in the form of a bit stream.
[0052] It should be understood that the signal processing processes S111 to S118 shown in FIG1 are merely exemplary examples of common signal processing processes in wireless communication systems. Wireless communication systems may also include signal processing processes such as resource mapping, precoding, interference cancellation, and CSI measurement. These signal processing processes can also be implemented through separate artificial intelligence (AI) models. For the sake of brevity, this application will not go into detail.
[0053] 2. Channel Estimation
[0054] Due to the complexity and time-varying nature of wireless channel environments, in wireless communication systems (e.g., the wireless communication systems described above), a receiver needs to recover received signals based on channel estimation results. Figure 2 is a schematic diagram of channel estimation and signal recovery applicable to embodiments of the present application.
[0055] As shown in FIG2 , in step S210 , the transmitter transmits, in addition to the data signal, a series of reference signals known to the receiver on the time-frequency resources, such as the channel state information-reference signal (CSI-RS) and the demodulation reference signal (DMRS).
[0056] In step S211, the transmitter transmits the above-mentioned data signal and reference signal to the transmitter through the channel.
[0057] The time-frequency resources occupied by the reference signal are different from the time-frequency resources occupied by the data signal.
[0058] In step S212, after receiving the reference signal, the receiver may perform channel estimation. In one possible implementation, the receiver may estimate channel information of the channel transmitting the reference signal using a channel estimation algorithm (e.g., a least squares (LS) channel estimation) based on a pre-stored reference signal and the received reference signal.
[0059] In step S213, the receiver may recover the channel information on all time-frequency resources using an interpolation algorithm based on the channel information of the channel transmitting the pilot sequence, for use in subsequent CSI feedback or data recovery.
[0060] Based on the above description in conjunction with Figure 2, it can be seen that the time-frequency resources for transmitting reference signals and the time-frequency resources for transmitting data signals are different time-frequency resources. In addition, some communication protocols (for example, the NR communication protocol) stipulate that the symbols used to transmit reference signals (hereinafter referred to as "pilot symbols") and the symbols used to transmit data signals (hereinafter referred to as "data symbols") are different. Figure 3 shows the patterns of data symbols and pilot symbols under different configurations.
[0061] As shown in Figure 3(a), in a resource block (RB), pilot symbols are distributed every other symbol across multiple REs corresponding to symbol 2 within the RB. As shown in Figure 3(b), in an RB, pilot symbols occupy part of multiple symbols corresponding to symbols 2 and 10 within the RB. As shown in Figure 3(c), in an RB, pilot symbols occupy multiple groups of REs within symbol 2 within the RB, where each group of REs includes two consecutive resource elements (REs) in the frequency domain.
[0062] Generally, different patterns in the patterns shown in Figures 3(a) to 3(c) can be adapted to different communication environments. In some implementations, when the terminal device is moving at a high speed and the channel characteristics vary rapidly, a pattern with a denser distribution of pilot symbols can be selected to help improve the accuracy of channel quality estimation for the entire RB. For example, the pattern shown in Figure 3(b) can be selected.
[0063] In other implementations, when the terminal device moves slowly and the channel characteristics vary slowly over time, a pattern with a sparser distribution of pilot symbols can be selected, which helps to reduce the overhead generated by transmitting reference signals while ensuring the accuracy of channel quality estimation for the entire RB.
[0064] 3. Neural Network
[0065] In recent years, artificial intelligence research, exemplified by neural networks, has achieved remarkable success in many fields, and will continue to play a vital role in people's lives and production for a long time to come. A neural network can be understood as a computational model consisting of multiple interconnected neuron nodes. The connections between these nodes represent the weighted values from input signals to output signals, often referred to as parameters. Each node performs a weighted summation of different input signals and outputs the result through a specific activation function.
[0066] As shown in Figure 4, neurons can rely on activation functions to implement nonlinear mapping, where the input of the neuron can be recorded as A, and each dimension of the input is recorded as a j , the corresponding parameter is recorded as w j, together with the summation units (SU), the input is strengthened or weakened. In addition, the output of SU can be input into the activation function f to obtain the output t, where the value of j is 1, 2, ..., n.
[0067] Common neural networks include convolutional neural network (CNN), recurrent neural network (RNN), deep neural network (DNN), etc.
[0068] The following describes a neural network applicable to embodiments of the present application in conjunction with FIG5 . The neural network shown in FIG5 can be divided into three categories based on the location of different layers: input layer 510 , hidden layer 520 , and output layer 530 . Generally speaking, the first layer is the input layer 510 , the last layer is the output layer 530 , and the intermediate layers between the first and last layers are all hidden layers 520 .
[0069] The input layer 510 is used to input data, where the input data can be, for example, a received signal received by a receiver. The hidden layer 520 is used to process the input data, for example, decompress the received signal. The output layer 530 is used to output processed output data, for example, a decompressed signal.
[0070] As shown in Figure 5, a neural network consists of multiple layers, each of which contains multiple neurons. The neurons between layers can be fully connected or partially connected. For connected neurons, the output of the neurons in the previous layer can serve as the input of the neurons in the next layer.
[0071] With the continuous advancement of neural network research, deep learning algorithms have been proposed in recent years. These algorithms introduce a large number of hidden layers into neural networks, forming DNNs. More hidden layers allow DNNs to better capture complex real-world situations. Theoretically, a model with more parameters has higher complexity and a greater "capacity," meaning it can handle more complex learning tasks. These neural network models are widely used in pattern recognition, signal processing, optimization and combination, anomaly detection, and other fields.
[0072] CNN is a deep neural network with a convolutional structure, and its structure is shown in FIG6 , which may include an input layer 610 , a convolutional layer 620 , a pooling layer 630 , a fully connected layer 640 , and an output layer 650 .
[0073] Each convolution layer 620 may include a plurality of convolution operators, which are also called kernels. The convolution operator can be regarded as a filter for extracting specific information from the input signal. The convolution operator can essentially be a parameter matrix, which is usually predefined.
[0074] The parameter values in these parameter matrices need to be obtained through a lot of training in practical applications. The parameter matrices formed by the parameter values obtained through training can extract information from the input signal, thereby helping CNN to make correct predictions.
[0075] When CNN has multiple convolutional layers, the initial convolutional layer tends to extract more general features, which can also be called low-level features. As the depth of CNN increases, the features extracted by the subsequent convolutional layers become more and more complex.
[0076] Pooling layer 630 is often needed to reduce the number of training parameters. Therefore, it is often necessary to periodically introduce a pooling layer after the convolution layer. For example, as shown in Figure 6, a convolution layer can be followed by a pooling layer, or multiple convolution layers can be followed by one or more pooling layers. In the signal processing process, the sole purpose of the pooling layer is to reduce the spatial size of the extracted information.
[0077] The fully connected layer 640, after being processed by the convolution layer 620 and the pooling layer 630, is not sufficient for CNN to output the required output information. Because as mentioned above, the convolution layer 620 and the pooling layer 630 only extract features and reduce the parameters brought by the input data. However, in order to generate the final output information (for example, the bit stream of the original information transmitted by the transmitter), CNN also needs to use the fully connected layer 640. Generally, the fully connected layer 640 may include multiple hidden layers, and the parameters contained in the multiple hidden layers can be pre-trained according to the relevant training data of the specific task type. For example, the task type may include decoding the data signal received by the receiver. For example, the task type may also include channel estimation based on the reference signal received by the receiver.
[0078] Following the multiple hidden layers in the fully connected layer 640, the final layer of the CNN is the output layer 650, which is used to output the results. Typically, this output layer 650 is configured with a loss function (e.g., a loss function similar to categorical cross entropy) to calculate the prediction error, or to evaluate the degree of difference between the CNN model's output (also known as the predicted value) and the ideal result (also known as the true value).
[0079] To minimize the loss function, the CNN model needs to be trained. In some implementations, the CNN model can be trained using a backpropagation algorithm (BP). The BP training process consists of a forward propagation process and a backward propagation process. During the forward propagation process (e.g., the propagation from 610 to 650 in Figure 6 is forward propagation), the input data is fed into the aforementioned layers of the CNN model, processed layer by layer, and transmitted to the output layer. If the output result differs significantly from the ideal result, the aforementioned loss function is minimized as the optimization goal, and the backward propagation process is switched to (e.g., the propagation from 650 to 610 in Figure 6 is backward propagation). The partial derivatives of the optimization goal with respect to each neuron weight are calculated layer by layer, forming the gradient of the optimization goal with respect to the weight vector, which serves as the basis for modifying the model parameters. The CNN training process is completed during the parameter modification process. When the aforementioned error reaches the desired value, the CNN training process ends.
[0080] It should be noted that the CNN shown in Figure 6 is only an example of a convolutional neural network. In specific applications, the convolutional neural network can also exist in the form of other network models, which is not limited in this embodiment of the present application.
[0081] RNNs are designed to process sequential data. In traditional neural network models (for example, CNN models), the layers are fully connected, from the input layer to the hidden layer to the output layer, and the nodes within each layer are disconnected. However, these ordinary neural networks are inadequate for many problems. For example, if you want to predict the next word in a sentence, you generally need to use the previous word, because the previous and next words in a sentence are not independent. RNNs are called recurrent neural networks because the current output of a sequence is also related to the previous output. Specifically, the network remembers the previous information and applies it to the calculation of the current output. That is, the nodes between hidden layers are no longer disconnected but connected, and the input of the hidden layer includes not only the output of the input layer but also the output of the hidden layer at the previous moment. In theory, RNNs can process sequence data of any length.
[0082] Training an RNN is similar to training a traditional ANN (artificial neural network). The same backpropagation error algorithm is used, but there is a slight difference. If the RNN is expanded, the parameters W, U, and V are shared, while traditional neural networks are not. Furthermore, when using the gradient descent algorithm, the output of each step depends not only on the network state at the current step, but also on the state of the network at the previous steps. For example, at t = 4, three steps need to be propagated backward, and various gradients need to be added to the three subsequent steps. This learning algorithm is called backpropagation through time (BPTT).
[0083] Given the existence of artificial neural networks and convolutional neural networks, why do we still need recurrent neural networks? The reason is simple. Both convolutional and artificial neural networks assume that elements are independent of each other, and that input and output are also independent, like cats and dogs. However, in the real world, many elements are interconnected, such as the changes in stock prices over time. For example, someone said, "I love traveling, and my favorite place is Yunnan. I must visit __ someday." Everyone knows to fill in the blank with "Yunnan." This is because we infer this based on the context, but achieving this is quite difficult. Therefore, recurrent neural networks were developed. Their essence is: they have the ability to remember, just like humans. Therefore, their output depends on the current input and memory. To put it simply, RNNs are a unit structure that is reused.
[0084] At present, in order to solve the gradient explosion or vanishing problem of RNN, a long short-term memory (LSTM) model is obtained by transforming RNN. As shown in Figure 7, LSTM introduces a new memory unit c t (also called "cell state"), which is used for linear cyclic information transmission and outputs information to the external state h of the hidden layer. t At each moment t, c t It records historical information up to the current moment. Unlike RNNs, which only consider the most recent state, memory cells determine which states should be retained and which should be forgotten, addressing the shortcomings of traditional RNNs in long-term memory.
[0085] Continuing to refer to FIG7, in order to achieve the above state selection, the memory unit introduces a gate control mechanism to control the path of information transmission, similar to the gate in the data circuit, "0" means closed, and "1" means open. The memory unit includes a forget gate 710, an input gate 720, and an output gate 730. Among them, the forget gate is used to control the memory unit c at the previous moment.t-1 How much information needs to be forgotten? The input gate is used to control the candidate state at the current moment. How much information needs to be stored? The output gate is used to control the memory unit c at the current moment. t How much information needs to be output to the external state h t .
[0086] 4. Channel Estimation Based on AI Decoder
[0087] The channel estimation based on the AI decoder aims to realize channel estimation by processing the reference signal received by the receiver using the AI-based channel estimation module. Figure 8 shows the process of channel estimation based on the channel estimation module. Referring to Figure 8, the reference signal received by the receiver 800 is used as the input of the channel estimation module 810. Accordingly, the channel estimation module 810 processes the input reference signal to output channel information. In addition, in some implementations, other auxiliary information can be added in addition to the reference signal to improve the accuracy of the channel information output by the channel estimation module. For example, the original sequence of the reference signal pre-stored by the receiver 800, the energy level of the reference signal received by the receiver 800, the transmission delay when transmitting the reference signal, or the noise when transmitting the reference signal, etc. can also be input to the channel estimation module 810.
[0088] The above describes the communication process and terminology involved in the embodiments of the present application in conjunction with Figures 1 to 8, and the following describes the communication system applicable to the embodiments of the present application in conjunction with Figure 9.
[0089] FIG9 illustrates a wireless communication system 900 applicable to an embodiment of the present application. The wireless communication system 900 may include a network device 910.

For example, the UE can act as a scheduling entity that provides sidelink signals between UEs in V2X or D2D, etc. For example, a cellular phone and a car communicate with each other using sidelink signals. The cellular phone and smart home devices communicate without relaying the communication signal through the base station.
[0096] The network device in the embodiments of the present application may be a device for communicating with a terminal device, and may also be referred to as an access network device or a radio access network device. For example, the network device may be a base station. The network device in the embodiments of the present application may refer to a radio access network (RAN) node (or device) that connects a terminal device to a wireless network. A base station can broadly cover various names as follows, or be replaced with the following names, such as: NodeB, evolved NodeB (eNB), next generation NodeB (gNB), relay station, access point, transmission point (TRP), transmission point (TP), master station MeNB, secondary station SeNB, multi-standard radio (MSR) node, home base station, network controller, access node, wireless node, access point (AP), transmission node, transceiver node, baseband unit (BBU), remote radio unit (RRU), active antenna unit (AAU), remote radio head (RRH), central unit (CU), distributed unit (DU), positioning node, etc. A base station can be a macro base station, a micro base station, a relay node, a donor node or the like, or a combination thereof.

[0097] Base stations can be fixed or mobile. For example, a helicopter or drone can be configured to act as a mobile base station, and one or more cells can move based on the location of the mobile base station.

[0101] It should also be understood that all or part of the functions of the communication device in this application can also be implemented through software functions running on hardware, or through virtualization functions instantiated on a platform (such as a cloud platform).
[0102] With the development of technology, communication systems support multiple signal transmission methods. In other words, the transmitter can select a transmission method from multiple signal transmission methods to transmit the signal. Correspondingly, the receiver can receive the signal using the reception method supported by the receiver. However, when the receiver receives the signal based on the reception method, the signal reception performance is poor. The applicant discovered that the cause of the above problem is that the receiver cannot know the transmission method used by the transmitter when sending the signal. Therefore, the reception method used by the receiver does not match the transmission method used by the transmitter.
[0103] The following describes signal transmission methods, including orthogonal and non-orthogonal transmission. For ease of understanding, the following first describes non-orthogonal signal transmission methods, and then explains the mismatch between transmission and reception methods based on these two methods.
[0104] At present, in known communication systems, in order to improve the reliability of transmission signals, signals transmitted on multiple transmission resources are transmitted in an orthogonal transmission manner, wherein orthogonal transmission can be understood as processing the signals transmitted on multiple transmission resources into mutually orthogonal signals for transmission, and the orthogonal signals are transmitted independently of each other and do not interfere with each other. In the scenario of orthogonal transmission, for a certain transmission resource, it can only be used to transmit one signal at a time, resulting in low utilization of the transmission resources. On the other hand, when the total transmission resources are constant, if the number of transmission resources occupied by a certain signal (hereinafter referred to as the "first signal") increases, it means that the number of transmission resources that can be used to transmit other signals decreases, which may cause other signals to fail to be transmitted in a timely manner.
[0105] Taking the example of a first signal being a reference signal (also called a "pilot signal") and a second signal being a data signal, the pilot signal and the data signal are orthogonally transmitted on different transmission resources. This means that a given transmission resource can only be used to transmit either a data signal or a pilot signal at a given moment, resulting in low transmission resource utilization. On the other hand, given a fixed total number of transmission resources, if the number of transmission resources occupied by pilot signals increases, this means that the number of transmission resources available for transmitting data signals decreases, potentially preventing timely transmission of data signals. Alternatively, if the number of transmission resources occupied by data signals increases, this means that the number of transmission resources available for transmitting pilot signals decreases, potentially reducing the accuracy of channel estimation based on pilot signals.
[0106] Therefore, to address the above issues, a non-orthogonal transmission scheme has been introduced into the communication system. Based on this transmission scheme, multiple signals can be transmitted in a non-orthogonal manner on the same transmission resources. The transmission resources may include, for example, one or more of time domain resources, frequency domain resources, and code domain resources. Taking the first signal as a pilot signal as an example, the pilot signal and the data signal can be transmitted in a non-orthogonal manner on the same transmission resource, which helps improve the utilization of transmission resources. In addition, the number of transmission resources for transmitting the pilot signal or the data signal does not decrease, which helps to ensure the accuracy of channel estimation based on the pilot signal while transmitting the data signal in a timely manner.
[0107] However, signals based on non-orthogonal transmission place high demands on the receiving end, and the receiving scheme used by the receiving end needs to be able to demodulate multiple signals of non-orthogonal transmission. Therefore, for signals based on non-orthogonal transmission, the receiving end needs to adopt a receiving method that matches the non-orthogonal transmission method, for example, receiving non-orthogonal transmitted signals based on an AI receiver. However, as mentioned above, the receiving end often cannot know the transmission method adopted by the transmitting end. At this time, if the transmitting end sends the signal based on the non-orthogonal transmission method, the receiving end will receive it based on a traditional receiver (for example, a non-AI receiver), resulting in the received signal being unable to be well distinguished, which reduces the signal reception performance.
[0108] Therefore, in response to the above-mentioned problems, an embodiment of the present application provides a method for wireless communication, in which first information for determining a receiving mode (also known as a first receiving mode) that matches a sending mode (also known as a first sending mode) is introduced. In this way, the first information is transmitted between the first device and the second device, which helps the receiving end and the sending end to use matching receiving modes and sending modes during the transmission of the first signal between the first device and the second device. Compared with the traditional signal transmission process in which the receiving end cannot select a receiving mode that matches the signal sending mode, this helps to improve the signal reception performance.
[0109] It should be noted that the first device may be the transmitter of the first signal, and the second device may be the receiver of the first signal. Alternatively, the first device may be the receiver of the first signal, and the second device may be the transmitter of the first signal. The transmitter may be a network device or a terminal device, and the receiver may be a network device or a terminal device, but this is not limited in the present embodiment.
[0110] For ease of understanding, the following describes a wireless communication method according to an embodiment of the present application in conjunction with FIG10 . The method shown in FIG10 includes step S1010 .
[0111] In step S1010, the first device sends first information to the second device, where the first information is used to determine a first receiving mode that matches the first sending mode.
[0112] In some implementations, the first transmission mode is used for non-orthogonal transmission of the first signal on the target transmission resource. Therefore, the first transmission mode can also be referred to as the "first processing mode" or the "first transmission scheme" or the "transmission scheme for transmitting the first signal". Accordingly, the first device can use the first transmission mode (or the first transmission mode) to send the first signal on the target transmission resource. For example, the first transmission mode can process the first signal based on the first model (for example, linear superposition and / or nonlinear superposition) so that the first signal can be non-orthogonally transmitted with other signals on the target transmission resource. The first model can be, for example, an AI model or a machine learning (ML) model.
[0113] Taking the first signal as a pilot signal as an example, the first transmission mode can indicate the transmission resources occupied by the first signal, or in other words, the first transmission mode can indicate the transmission resources occupied by the first signal when it is transmitted in a non-orthogonal manner. For example, the first transmission mode can be used to indicate a pilot pattern.
[0114] In some implementations, the first receiving mode is used to receive the first signal on the target transmission resource. That is, the second device receives the first signal on the target transmission resource using the first receiving mode. It should be understood that in the embodiment of the present application, the reception of the first signal may include the process of processing the first signal. For example, the reception of the first signal may include the process of decoding the first signal. For another example, if the first signal is a pilot signal, the reception of the first signal may include the process of performing channel estimation based on the pilot signal. Therefore, in the embodiment of the present application, the first receiving mode may be replaced by "first processing mode" or "first processing scheme" or "processing scheme for processing the first signal". Of course, in the embodiment of the present application, the reception of the first signal may also only include the process of receiving the first signal, without including the process of processing the first signal.
[0115] In some implementations, the first receiving mode may receive the first signal based on the second model. Taking the first signal as a pilot signal as an example, the first receiving mode may include a channel estimation scheme based on the second model. The second model may be an AI model or an ML model. For example, the second model may include one or more of the following models: a fully connected neural network (FCN), a CNN, an RNN, and a transformer model.
[0116] As mentioned above, the first signal may be a pilot signal, and accordingly, the signal for non-orthogonal transmission on the target transmission resource may include a pilot signal and other signals. The embodiment of the present application does not specifically limit other signals, and other signals may be, for example, data signals. Taking the example that the signal for non-orthogonal transmission includes a pilot signal and a data signal, the first receiving method may include a data parsing method based on the second model, or in other words, parsing the data signal in the received signal based on the second model. Of course, in the embodiment of the present application, the above-mentioned first receiving method may also include a data parsing scheme based on the second model, and a channel estimation scheme based on the second model. Alternatively, the above-mentioned first receiving method may also only include a channel estimation scheme based on the second model.
[0117] It should be noted that if the first receiving mode includes a data parsing scheme based on the second model and a channel estimation scheme based on the second model, then the second model used for the data parsing scheme and the second model used for the channel estimation scheme may be different. At this time, it can be understood that the second model may include multiple different models, one (or some) of the multiple models is used for the data parsing scheme, and the remaining models of the multiple models are used for the channel estimation scheme. Of course, in an embodiment of the present application, the second model used for the data parsing scheme and the second model used for the channel estimation scheme may be the same model.
[0118] In some implementations, the first receiving mode matches the first sending mode, which can be replaced by the first receiving mode of the first signal corresponding to the first sending mode. As described above, in the embodiments of the present application, the first receiving mode can be replaced by the "first processing scheme", and the first sending mode can be replaced by the "first transmission scheme". Accordingly, the first information is used to determine the first receiving mode that matches the first sending mode, which can be replaced by the first information being used to determine the first processing scheme that matches the first transmission scheme.
[0119] Taking the example of a first transmission mode including a non-orthogonal transmission mode, the corresponding first reception mode may be a reception mode in which a receiver based on the second model receives the first signal. Taking the example of a first transmission mode used for non-orthogonal transmission of a pilot signal and a data signal, the first reception mode is used for one or more of the following: a pilot signal decoding scheme based on the second model, a channel estimation scheme based on the second model, and a data parsing scheme based on the second model. The data parsing scheme based on the second model is used to receive data signals transmitted non-orthogonally to the first signal.
[0120] In some implementations, the first sending mode is associated with one or more of the following: a sequence of the first signal; the transmission power of the first signal; a transmission scenario of the first signal; a transmission condition of the first signal; a transmission resource used to transmit the first signal; and a training result of a first model, the first model being used to process the first signal to be transmitted.
[0121] It should be noted that the first sending mode is associated with the information, which can be understood as the indication information of the first sending mode is associated with the information. The following will be introduced in conjunction with Table 1, and for the sake of brevity, it will not be repeated here.
[0122] If the first transmission mode is associated with a transmission resource used to transmit the first signal, where the transmission resource used to transmit the first signal may be determined based on a pattern of the first signal, then the first transmission mode is associated with the pattern of the first signal. The pattern of the first signal is used to indicate the transmission resource of the first signal. For example, if the first signal is a pilot signal, the pattern of the first signal may be a pilot pattern.
[0123] Taking the transmission resource as a time domain resource as an example, in some implementations, the pattern of the first signal is used to indicate that the first signal occupies a time domain resource of a first time domain length. The time domain resource of the first time domain length may, for example, include one time domain resource or multiple time domain resources. The time domain resource may, for example, be a time domain symbol, a time slot, or the like. For example, the pattern of the first signal indicates that the first signal occupies the a1th symbol within the time slot. For example, the pattern of the first signal indicates that the first signal occupies the a1th symbol and the a2th symbol within the time slot. For example, the pattern of the first signal indicates that the first signal occupies the a1th symbol, the a2th symbol, and the a3th symbol within the time slot. For example, the pattern of the first signal indicates that the first signal occupies the a1th symbol, the a2th symbol, the a3th symbol, and the a4th symbol within the time slot. For example, the pattern of the first signal indicates that the first signal occupies the a1th symbol to the a7th symbol within the time slot. For example, the pattern of the first signal indicates that the first signal occupies the a1th symbol to the a8th symbol within the time slot.
[0124] It should be noted that the values of a1 to a8 can be between 1 and K, where K is a positive integer. For example, the values of K can include 12, 24, 48, and 60. Accordingly, if K = 14, then a1 = 3, a2 = 6, a3 = 10, and a4 = 13. For example, if K = 28, then a1 = 2, a2 = 4, a3 = 6, a4 = 8, a5 = 10, a6 = 12, and a7 = 17.
[0125] In addition, the above-mentioned a1-a8 can be determined based on the index of the time domain resource. For example, a1-a8 can be the index of the time domain resource. For another example, a1-a8 can be calculated using the index of the time domain resource. The index of the time domain resource can be sequentially indexed from early to late in the time domain, or the index of the time domain resource can be sequentially indexed from late to early in the time domain.
[0126] Taking frequency domain resources as an example, in some implementations, the pattern of the first signal is used to indicate that the first signal occupies frequency domain resources within a first frequency domain range. The frequency domain resources within the first frequency domain range may, for example, include one or more frequency domain resources. The frequency domain resources may, for example, be subcarriers. For example, the pattern of the first signal indicates that the first signal occupies the b1th subcarrier within an RB. For example, the pattern of the first signal indicates that the first signal occupies the b1th subcarrier and the b2th subcarrier within an RB. For example, the pattern of the first signal indicates that the first signal occupies the b1th subcarrier, the b2th subcarrier, and the b3th subcarrier within a timeslot. For example, the pattern of the first signal indicates that the first signal occupies the b1th subcarrier, the b2th subcarrier, the b3th subcarrier, and the b4th subcarrier within an RB. For example, the pattern of the first signal indicates that the first signal occupies the b1th to b7th subcarriers within a timeslot. For example, the pattern of the first signal indicates that the first signal occupies the b1th to b8th subcarriers within a timeslot.
[0127] It should be noted that the values of b1 to b8 can be between 1 and M, where M is a positive integer. For example, the values of M can include 12, 24, 48, and 60. Accordingly, for example, if M = 11, then b1 = 3, b2 = 6, b3 = 10, and b4 = 13. If M = 24, then b1 = 2, b2 = 4, b3 = 6, b4 = 8, b5 = 10, and b6 = 12.
[0128] If the first sending mode is associated with a transmission scenario of the first signal, wherein the transmission scenario of the first signal is associated with one or more of the following: a cell transmitting the first signal; an environment transmitting the first signal; and a mobile state of the first device and / or the second device.
[0129] Taking the association of the transmission scenario of the first signal with the cell transmitting the first signal as an example, alternatively, the transmission scenario of the first signal can be associated with the cell type of the cell transmitting the first signal. The cell type may include one or more of the following: macro cell, normal cell, or small cell. Typically, to improve the transmission performance of the first signal, the transmission method of the first signal may vary slightly in different cells.
[0130] Taking the example of the association between the transmission scenario of the first signal and the environment in which the first signal is transmitted, alternatively, the transmission scenario of the first signal and the environment in which the first signal is transmitted may be associated. The environment in which the first signal is transmitted may include, for example, an indoor environment or an outdoor environment. Generally, to improve the transmission performance of the first signal, the transmission method used for transmitting the first signal may vary slightly for different environments.
[0131] Taking the example of associating the transmission scenario of the first signal with the mobility state of the first device and / or the second device, in some implementations, the mobility state may include moving or stationary. In other implementations, the mobility state may include a moving speed, where the moving speed may be classified into one or more levels: low speed, medium speed, high speed, ultra-high speed, etc. Generally, to improve the transmission performance of the first signal, the transmission method used for transmitting the first signal may vary slightly for different mobility states.
[0132] If the first sending mode is associated with the transmission condition of the first signal, the transmission condition of the first signal is associated with one or more of the following: the transmission configuration of the first signal; the antenna configuration of the first signal; and the channel characteristics of the channel transmitting the first signal.
[0133] In some implementations, the transmission configuration of the first signal is used to indicate the frequency domain resources for transmitting the first signal. For example, the transmission configuration of the first signal can be used to indicate the number of frequency domain resources for transmitting the first signal, where the frequency domain resources can include, for example, bandwidth and subbands. In other implementations, the transmission configuration of the first signal is used to indicate the time domain resources for transmitting the first signal. For example, the transmission configuration of the first signal can be used to indicate the number of time domain resources for transmitting the first signal, where the time domain resources can include, for example, time slots and subframes.
[0134] In some implementations, the antenna configuration may include a transmit antenna port configuration and / or a receive antenna port configuration.
[0135] In some implementations, the channel characteristics of the channel for transmitting the first signal are used to indicate performance of transmitting the first signal in the channel. The channel characteristics may include, for example, one or more of line-of-sight (LOS) channel characteristics, non-line-of-sight (NLOS) channel characteristics, multipath characteristics, and frequency-selective characteristics.
[0136] If the first transmission mode is associated with the transmit power of the first signal, in some implementations, the transmit power of the first signal may be determined based on a fixed transmit power (e.g., absolute transmit power). For example, within the resource set where the target transmission resource is located, the transmit power of the first signal used for non-orthogonal transmission may all be fixed transmit power. For another example, on some transmission resources within the resource set where the target transmission resource is located, the transmit power of the first signal used for non-orthogonal transmission may be determined based on transmit power 1, while on other transmission resources within the resource set, the transmit power of the first signal used for non-orthogonal transmission may be determined based on transmit power 2. In other words, the transmit power of the first signal used for non-orthogonal transmission within the resource set varies. Taking the first signal as a pilot signal as an example, all pilot signals within the resource set are transmitted using transmit power P1.
[0137] Assume that the first signal is a pilot signal, and the pilot signal is sent using transmission power P2 on the p1th symbol to the p2th symbol in the resource set, the pilot signal is sent using transmission power P3 on the p3th symbol to the p4th symbol in the resource set, and the pilot signal is sent using transmission power P4 on the p5th symbol to the p6th symbol in the resource set, wherein the transmission power P2, the transmission power ratio P3 and the transmission power ratio P4 are all different.
[0138] Assuming that the first signal is a pilot signal, the pilot signal is sent using a transmission power of P5 on the p1th symbol to the p2th symbol within the resource set, the pilot signal is transmitted using a transmission power of P6 on the p3th symbol to the p4th symbol within the resource set, and the pilot signal is transmitted using a transmission power of P7 on the p5th symbol to the p6th symbol within the resource set, wherein the transmission power P5, the transmission power ratio P6, and the transmission power ratio P7 are all different.
[0139] In some other implementations, the transmit power of the first signal may be determined based on a fixed transmit power ratio, wherein the transmit power ratio is used to indicate the ratio between the transmit power of the first signal on the target transmission resource and the total transmit power of multiple signals transmitted in a non-orthogonal manner. For example, within the resource set where the target transmission resource is located, the transmit power of the first signal used for non-orthogonal transmission may all be determined based on the transmit power ratio. For another example, on some transmission resources within the resource set where the target transmission resource is located, the transmit power of the first signal used for non-orthogonal transmission may be determined based on a transmit power ratio of 1, while on other transmission resources within the resource set, the transmit power of the first signal used for non-orthogonal transmission may be determined based on a transmit power ratio of 2. In other words, the transmit power ratio of the first signal used for non-orthogonal transmission within the resource set varies.
[0140] Assuming that the first signal is a pilot signal, the pilot signal is sent using a transmission power ratio of P2 on the p1th symbol to the p2th symbol in the resource set, the pilot signal is sent using a transmission power ratio of P3 on the p3th symbol to the p4th symbol in the resource set, and the pilot signal is sent using a transmission power ratio of P4 on the p5th symbol to the p6th symbol in the resource set, wherein the transmission power ratio P2, the transmission power ratio P3 and the transmission power ratio P4 are all different.
[0141] Assuming that the first signal is a pilot signal, the pilot signal is sent using a transmission power ratio of P5 on the p1th symbol to the p2th symbol within the resource set, the pilot signal is transmitted using a transmission power ratio of P6 on the p3th symbol to the p4th symbol within the resource set, and the pilot signal is transmitted using a transmission power ratio of P7 on the p5th symbol to the p6th symbol within the resource set, wherein the transmission power ratio P5, the transmission power ratio P6 and the transmission power ratio P7 are all different.
[0142] It should be noted that in the embodiments of the present application, the above transmit power ratio is not limited. For example, the transmit power ratio may include one or more of the following ratios: 1%, 2%, 5%, 10%, 20%, 25%, 33%, 40%, 50%, 60%, 66%, 70%, 75%, 80%, 90%, 95%, and 99%.
[0143] It should be noted that, in the embodiments of the present application, there is no limitation on the resource set. The resource set may include one or more transmission resources, for example, the resource set may be an RB, and correspondingly, the above-mentioned transmission resource may be an RE.
[0144] If the first transmission mode is associated with the sequence of the first signal. In an embodiment of the present application, the sequence of the first signal is not limited. For example, the sequence of the first signal can be determined based on one or more of the following target sequences: a pseudo-random sequence (for example, a Gold sequence), a ZC (zadoff-chu) sequence, an m sequence, an all-1 sequence, a sequence processed based on one or more modulation modes of quadrature phase shift keying (QPSK), 16-quadrature amplitude modulation (16QAM), and 64-phase quadrature amplitude modulation (64QAM).
[0145] It should be noted that, in some implementations, the sequence of the first signal is determined based on the target sequence, which may include the first signal sequence being the target sequence. In other implementations, the sequence of the first signal is determined based on the target sequence, which may include the first signal sequence being obtained by processing the target sequence.
[0146] If the first transmission mode is associated with the training result of the first model, the first model is used to process the first signal to be transmitted. In some implementations, the transmit power of the first signal may be based on the first model, wherein the first model is used to process the first signal to be transmitted and other signals (e.g., linear superposition and / or nonlinear superposition) so that the processed signals can be transmitted in a non-orthogonal transmission mode. The transmit power ratio is used to indicate the ratio between the transmit power of the first signal on the target transmission resource and the total transmit power of multiple signals transmitted in non-orthogonal manner.
[0147] In other implementations, the sequence of the first signal may be based on the first model. For example, the sequence of the first signal may be obtained by adjusting the target sequence using the first model, or in other words, the sequence of the first signal comes from the first signal sequence training results of different first models.
[0148] In the embodiments of the present application, any of the above-mentioned information can be individually associated with the first transmission method. Of course, in the embodiments of the present application, the first transmission method can also be associated with at least two of the above-mentioned information. In addition, the embodiments of the present application do not limit the method of association. For example, the association between the first transmission method and the above-mentioned information can be defined by a formula. For another example, the association between the first transmission method and the above-mentioned information can be defined by a table, where the table can be configured, preconfigured, or predefined.
[0149] For ease of understanding, the above-mentioned association relationship is introduced below in conjunction with Table 1. Assume that the association relationship is the association relationship between the transmission mode, the transmission resources (time domain resources and frequency domain resources) used to transmit the first signal, and the transmission power of the first signal. Referring to Table 1, it can be seen that if the index of the first transmission mode is 1, the time domain resources for transmitting the first signal are all time domain symbols, the frequency domain resources for transmitting the first signal are all frequency domain subcarriers, and the transmission power of the first signal is the default first signal power scheme, wherein the default power scheme indicates that the transmission power ratio of the first signal is 25%. If the index of the first transmission mode is 2, the time domain resources for transmitting the first signal are the first time domain pattern, wherein the first time domain pattern indicates that the symbols for transmitting the first signal are separated by f symbols, f=1, 2; the frequency domain resources for transmitting the first signal are the first frequency domain pattern, wherein the first frequency domain pattern indicates that the subcarriers for transmitting the first signal are separated by d subcarriers, d=1, 2; the transmission power of the first signal is the first power scheme, wherein the first power scheme indicates that the transmission power ratio of the first signal is 20%. If the index of the first transmission mode is 3, the time domain resources used to transmit the first signal are the second time domain pattern; the frequency domain resources used to transmit the first signal are the second frequency domain pattern; and the transmit power of the first signal is the second power scheme. If the index of the first transmission mode is 4, the time domain resources used to transmit the first signal are the third time domain pattern; the frequency domain resources used to transmit the first signal are the third frequency domain pattern; and the transmit power of the first signal is the third power scheme.
[0150] Table 1
[0151] It should be noted that the above-mentioned first transmission mode may be one of multiple transmission modes supported by the transmitting end, wherein the multiple transmission modes may include an orthogonal transmission mode and / or a non-orthogonal transmission mode. Of course, in the embodiment of the present application, the multiple transmission modes may also include the multiple transmission modes described above. In addition, the above-mentioned first reception mode may be one of multiple reception modes supported by the transmitting end, wherein the reception mode may include reception based on a traditional receiver and / or reception based on a receiver of the second model, wherein the second model can refer to the introduction above.
[0152] Based on the foregoing introduction, it can be known that the above information (for example, the sequence of the first signal, the transmission power of the first signal, the transmission scenario of the first signal, the transmission condition of the first signal, the transmission resource used to transmit the first signal, and the training result of the first model) will affect the first sending mode to a certain extent. Accordingly, if the first sending mode changes, the first receiving mode corresponding to the first sending mode will also change. Therefore, it can be understood that the association relationship between the first sending mode and the first receiving mode is associated with one or more of the above information, or that the association relationship between the first sending mode and the first receiving mode is affected by the above one or more information. Of course, in the embodiment of the present application, it can also be understood that the first receiving scheme is associated with one or more of the above information.
[0153] That is to say, the matching relationship (or association relationship) between the above-mentioned first sending mode and the first receiving mode is associated with one or more of the following: the sequence of the first signal; the transmission power of the first signal; the transmission scenario of the first signal; the transmission condition of the first signal; the transmission resources used to transmit the first signal; the training result of the first model, and the first model is used to process the first signal to be sent.
[0154] It should be noted that, as introduced above, the first signal can be associated with multiple sending methods, and accordingly, the first signal can also be associated with multiple receiving methods. At this time, there can be an association relationship between the multiple sending methods and the multiple receiving methods, wherein the association relationship can include the association relationship between the above-mentioned first sending method and the first receiving method.
[0155] In the embodiments of the present application, the aforementioned association is not specifically limited. For example, the aforementioned association may indicate that different sending modes correspond to different receiving modes. For another example, the aforementioned association may indicate that some of the different sending modes correspond to different receiving modes. Of course, in the embodiments of the present application, the aforementioned association may indicate that different sending modes correspond to the same receiving mode.
[0156] In addition, in an embodiment of the present application, the above-mentioned association relationship can be a direct association relationship between the sending mode and the receiving mode. For example, the indication information of the first sending mode is directly associated with the indication information of the first receiving mode. Of course, in an embodiment of the present application, the association relationship between the first receiving mode and the first sending mode can also be associated through the second information. In other words, the above-mentioned association relationship includes the association relationship between the first sending mode and the second information, and the association relationship between the first receiving mode and the second information. In other words, the first receiving mode is determined based on one or more second information.
[0157] In some implementations, the one or more second information includes: indication information of the first sending method; configuration information of the first signal; and transmission scenario of the first signal.
[0158] Taking the example of the second information including the indication information of the first sending mode, the first receiving mode associated with the first sending mode can be determined based on the association relationship between the receiving mode and the sending mode. The association relationship between the sending mode and the receiving mode can be referred to above and will not be repeated here for the sake of brevity.
[0159] Taking the example of the second information including the configuration information of the first signal, the configuration information of the first signal associated with the first transmission mode can be determined based on the association between the signal configuration information and the transmission mode. Correspondingly, the first reception mode associated with the configuration information of the first signal can be determined based on the association between the signal configuration information and the reception mode. The signal configuration information is similar to the configuration information of the first signal described above, and for the sake of brevity, reference is made to the above description.
[0160] Taking the transmission scenario in which the second information includes the first signal as an example, the transmission scenario of the first signal associated with the first sending mode can be determined based on the association between the transmission scenario of the signal and the sending mode. Accordingly, the first receiving mode associated with the transmission scenario of the first signal can be determined based on the association between the transmission scenario of the signal and the receiving mode.
[0161] In addition, in the embodiments of the present application, the above-mentioned association relationship can be configured, for example, by a network device. The above-mentioned association relationship can also be predefined, for example, by a communication protocol. Of course, the above-mentioned association relationship can also be preconfigured, for example, it can be preconfigured when the first device and / or the second device leaves the factory.
[0162] The above describes the first sending mode and the first receiving mode in the embodiment of the present application. The following describes the first information in the embodiment of the present application in combination with Examples 1 to 2. It should be noted that, in the embodiment of the present application, the first device may be the transmitter of the first signal, and the second device may be the receiver of the first signal. Taking the first signal as an uplink signal (for example, an uplink pilot) as an example, the first device may be a terminal device, and correspondingly, the second device may be a network device. Taking the first signal as a downlink signal (for example, a downlink pilot) as an example, the first device may be a network device, and correspondingly, the second device may be a terminal device.
[0163] Example 1: The first information includes indication information of the first sending method.
[0164] In other words, the first information is used to indicate the first transmission mode. For example, the first information may carry an index of the first transmission mode. Taking the first signal as a pilot signal as an example, the index of the first transmission mode may be a pilot pattern of the pilot signal.
