[0064] It should be noted that Figure 1 is merely an example of a system applicable to this application. Of course, the methods described in the embodiments of this application can also be applied to other systems. Furthermore, the terms "system" and "network" are often used interchangeably herein.

It should also be understood that in the embodiments of the present application, the “protocol” may refer to a standard protocol in the field of communications, for example, it may include LTE protocols, NR protocols, and related protocols used in future communication systems, and this application does not limit this.

[0065] In a wireless communication system, the basic workflow may include the following:

[0066] At the transmitting end, the transmitter (also called the transmitter or transmitting device) encodes and modulates the source bit stream to obtain modulation symbols. Pilot symbols are inserted into the modulated symbols for channel estimation and symbol detection at the receiving end (also called the receiver or receiving device). Ultimately, the transmitted signal is formed and reaches the receiving end through the channel. At the receiving end, the receiver first uses the pilot (the same as the pilot signal or pilot symbol) to perform channel estimation and then feeds back Channel State Information (CSI) to the transmitting end via a feedback link. This information allows the transmitter to adjust at least one of the channel coding, modulation, and precoding methods. Finally, the receiver performs symbol detection, demodulation, and channel decoding to obtain the final recovered bit stream.

[0067] Due to the complexity and time-varying nature of the wireless channel environment, in wireless communication systems, the receiver's estimation and recovery of the wireless channel will affect the final data recovery performance.

[0068] FIG2 is a schematic diagram of a channel estimation and recovery process provided by an embodiment of the present application. As shown in FIG2 , the transmitter allocates data symbols and pilot symbols (reference signals) known to the receiver at different resource positions (e.g., time domain and frequency domain), such as a Channel State Information Reference Signal (CSI-RS), a Demodulation Reference Signal (DMRS), a Phase Tracking Reference Signal (PTRS or PT-RS), a Sounding Reference Signal (SRS), a Synchronization Signal Block (SSB), a Positioning Reference Signal (PRS), and at least one of the reference signals. An SSB may also be referred to as a Synchronization Signal / Physical Broadcast Channel Block (SS / PBCH block). After transmission through the channel, the receiver reaches the receiving end. During the channel estimation phase, the receiver can estimate the channel information at the resource location where the pilot symbol is placed based on the real pilot (i.e., the pilot symbol known to the receiver) and the received pilot (i.e., the pilot symbol received by the receiver). The receiver can also recover the full channel information (e.g., using an interpolation algorithm) based on the estimated channel information at the pilot location for subsequent channel information feedback or data recovery. Optionally, the channel information estimation method may include at least one of the following: least squares (LS), linear minimum mean square error (LMMSE), etc.

[0069] In NR, data symbols and pilot symbols (i.e., reference signals) are placed in different resource locations.

[0070] In any embodiment of the present application, any two of the pilot signal, the reference signal, and the control signal may be replaced with each other.

[0071] Figure 3 is a schematic diagram of a resource allocation pattern for data symbols and pilot symbols provided in an embodiment of the present application. As shown in Figure 3, data symbols and pilot symbols in the time domain and / or frequency domain and / or code domain resources are independent and orthogonal to each other, that is, only one of the data symbols or pilot symbols can be placed in the same resource position. Different resource allocation patterns can be adapted to different wireless environments. For example, when the terminal device is moving at a high speed, the channel characteristics vary rapidly over time, and it is necessary to place more dense pilot symbols in the time domain dimension to ensure the channel estimation quality of the entire channel.

[0072] It should be noted that although Figure 3 shows only three resource allocation patterns for data symbols and pilot symbols, there are many other resource allocation patterns for data symbols and pilot symbols. The embodiments of the present application do not limit the resource allocation patterns for data symbols and pilot symbols.

[0073] Based on the current common pilot configuration, some solutions can implement channel estimation based on artificial intelligence (AI) / machine learning (ML) neural networks.

[0074] Figure 4 is a schematic diagram of a channel estimation provided by an embodiment of the present application. As shown in Figure 4, the channel estimation of Figure 4 is implemented by an AI / ML-based channel estimation module. The AI / ML-based channel estimation module can be implemented by at least one of the following: Deep Neural Networks (DNN), Convolutional Neural Networks (CNN), Fully Convolutional Networks (FCN), Recurrent Neural Networks (RNN), Transformer Neural Networks, etc.

[0075] The input of the AI / ML-based channel estimation module is the received signal corresponding to the pilot symbol (i.e., the pilot signal received by the receiver) and the transmitted signal corresponding to the pilot symbol (i.e., the pilot symbol known to the receiver). The output is the channel estimation result, which can be the channel estimation result of the pilot position or the channel estimation result of the entire channel.

[0076] In related technologies, pilot signals and data signals are placed orthogonally in time, frequency, and code domain resources. That is, when the total transmission resources are constant, the increase in resource overhead required for the pilot means that the resources used for data transmission are reduced, and the data transmission resource utilization rate is relatively low.

[0077] The embodiments of the present application propose that the pilot signal and data be transmitted in a non-orthogonal manner, for example, the pilot signal and data are transmitted simultaneously on the same time domain and frequency domain resources. The receiving end can achieve effective channel estimation or data reception from the mixed transmission of the pilot signal and data. Optionally, the receiving end can use an advanced receiver (such as an AI / ML receiver) to achieve effective channel estimation or data reception from the mixed transmission of the pilot signal and data.

[0078] In some scenarios, when the above-mentioned scheme of mixed transmission of pilot signals and data signals is adopted, the pilot signal transmission scheme is highly correlated with the reception scheme. For example, if the pilot transmission adopts the first scheme, and the receiver does not adopt the first reception and processing scheme that matches the first pilot transmission scheme, it will cause the receiver to fail to work or the receiver performance to be significantly lost.

[0079] Based on the above problems, different terminal devices may support different superimposed reference signals, and different superimposed reference signals may be received and processed. For example, due to different terminal device capabilities, different models for processing superimposed pilot signals by terminal devices, and different degrees of support for superimposed reference signals under different conditions and scenarios. Different network devices may also support different superimposed reference signals, and different superimposed reference signals may be received and processed. For example, due to different network device capabilities, different models for processing superimposed pilot signals by network devices, and different degrees of support for superimposed reference signals under different conditions and scenarios. Compared with traditional reference signal transmission and reception, a specific superimposed reference signal can only be used in the system when both the terminal device and the network device support the transmission, reception, and processing of the specific superimposed reference signal. To achieve the above purpose, it is necessary to determine the usable superimposed pilot signals through capability interaction and information interaction between the terminal device and the network device.

[0080] In any embodiment of the present application, the terminal device may include a UE, and the network device may include a base station.

[0249] Determining a transmission power to be used based on a position of a reference signal transmitted non-orthogonally to the data signal and a signal sequence corresponding to the reference signal transmitted non-orthogonally to the data signal;

[0250] Reference signals transmitted non-orthogonally to data signals at different locations use different transmission powers;

[0251] Different signal sequences corresponding to reference signals transmitted non-orthogonally to data signals use different transmission powers.

[0252] Exemplarily, one transmission power setting includes: the transmission power of a reference signal transmitted non-orthogonally to the data signal is a first power; another transmission power setting includes: the ratio of the transmission power of the reference signal transmitted non-orthogonally to the data signal to the transmission power of the data signal is a first ratio, and the two transmission power settings are different. Further exemplarily, one transmission power setting includes: the transmission power of the reference signal transmitted non-orthogonally to the data signal is a first power; another transmission power setting includes: determining the transmission power to be used based on the position of the reference signal transmitted non-orthogonally to the data signal, and the two transmission power settings are different.

[0254] In any embodiment of the present application, the format sequence includes at least one of the following: a gold sequence, a ZC sequence, an m sequence, an all-1 sequence, a QPSK sequence, a 16QAM sequence, a 64QAM sequence, an OFDM sequence, etc.

[0256] Channel state information reference signal CSI-RS, demodulation reference signal DMRS, phase tracking reference signal PT-RS, sounding reference signal SRS, synchronization signal block SSB, positioning reference signal PRS.

Optionally, the reference signal includes an SRS. Optionally, the reference signal includes an SSB. Optionally, the reference signal includes a PRS.

[0258] The communication method of the present application is described below with the terminal device including UE and the network device including base station:

[0259] An embodiment of the present application provides a method for determining whether a first reference signal (a reference signal transmitted non-orthogonally to a data signal) is supported, which ones are supported, how to determine a set of first reference signals that can be used, and how to determine the first reference signal to be used between a UE and a base station.

[0260] In the first reference signal transmission scheme in the embodiment of the present application, the data (corresponding to the above-mentioned data signal) and the first reference signal can be transmitted on the same transmission resource, for example, on the same time domain and frequency domain resources, data and reference signals can be transmitted simultaneously. For example, at least one of the signals such as CSI-RS, DMRS, PT-RS, SRS, SSB, PRS, etc. can be transmitted on the same transmission resource as the transmitted data (superimposed transmission). This superimposed transmission method will bring requirements for the processing scheme, for example, it is necessary to adopt a first processing scheme that matches the above-mentioned transmission method and transmission configuration. For this transmission mechanism in which data and the first reference signal are superimposed on the same transmission resource, the first processing scheme can parse out at least one of the first reference signal, channel information (such as time domain channel, frequency domain channel, channel characteristics corresponding to the antenna, channel characteristics corresponding to the angle, etc.), data signal, etc. from the superimposed data and the first reference signal. The first processing scheme can be completed based on an AI / ML model. For example, the implementation method of the model can be based on one or a combination of a fully connected network (FCN), a convolutional neural network (CNN), a recurrent neural network (RNN), and a transformer neural network architecture.

[0261] Optionally, the difference between different first reference signals comes from the combined influence of one or more of the following influencing factors:

[0262] For example, the characteristics of different first reference signals come from different first reference signal patterns (for example, in the time domain, in a specific time domain length; for example, all symbols in one or more time slots, or specific one or more symbols in one or more time slots, have the first reference signal and data superimposed and transmitted; for example, in the frequency domain, in a specific frequency domain range, for example, all subcarriers in one or more resource blocks, or specific one or more subcarriers in one or more resource blocks, have the first reference signal and data superimposed and transmitted).

[0263] For example, different first reference signal power settings are used, such as using the same power to transmit the first reference signal at all first reference signal positions, such as a fixed first reference signal transmission power, or a fixed first reference signal transmission power to data power ratio; or using different power settings to transmit the first reference signal at different reference signal positions; or the power settings may be derived from different AI / ML first reference signal power training results;

[0264] For example, using different first reference signal sequences, such as the gold sequence, ZC sequence, m sequence, all-ones sequence, QPSK, 16QAM, 64QAM and other modulated special sequences, etc., AI / ML first reference signal sequence training results;

[0265] For example, different first reference signals are applied to different cells (such as macro cells, ordinary cells, small cells), scenarios (such as indoors, outdoors), UE mobility speeds (such as low, medium, high, ultra-high speed, etc.), transmission configurations (such as the number of frequency domain resources, bandwidth, subbands, the number of time domain resources, time slots, subframes), antenna configurations (such as transmitting antenna port configurations, receiving antenna port configurations), channel characteristics (such as LOS channels, NLOS channels, multipath characteristics, frequency selection characteristics), etc.

[0385] The present application provides a method for determining the superimposed pilots that can be supported by the UE and the base station by superimposing transmission of a reference signal and data. Since the scheme for transmitting the superimposed reference signal (first reference signal) is highly correlated with the scheme for processing the superimposed reference signal, a specific superimposed reference signal can be used in the system only when both the UE and the base station support the transmission, reception, and processing of a specific superimposed reference signal. At the same time, taking into account that different UEs may support different superimposed reference signals, the superimposed reference signals that can be received and processed may also be different, different base stations may support different superimposed reference signals, and the superimposed reference signals that can be received and processed may also have different characteristics, the present application will determine the usable superimposed reference signals (sets) and superimposed reference signal processing schemes (sets) through capability interaction and information interaction between the UE and the base station, thereby ensuring that the superimposed reference signals can be transmitted, received, and processed on both the UE and the base station.
