In recent years, due to the large-scale development of high-speed railways (HSR) and the increasing popularity of highway vehicle communication systems, wireless communication systems in high-speed mobile environments have attracted widespread attention. The 5G system is committed to providing bursty broadband services to users in trains or high-mobility vehicles running at speeds of up to 500km/h, ensuring a data transmission rate of 150Mbps. However, most of the current wireless communication systems can only guarantee a high data transmission rate and provide high-quality services in low-speed or medium-speed mobile environments, and severely limit their coverage and transmission efficiency in high-speed mobile scenarios.

The main problems faced by communication systems in high mobility scenarios include: first, fast time-varying fading. Due to the increase in mobility, the communication system has large Doppler frequency shift and expansion. These problems cause the communication performance to deteriorate seriously. At the same time, the change of terminal speed will cause the change of attenuation coefficient and time-varying Doppler expansion. The rapid change of wireless transmission environment increases the difficulty of channel analysis and modeling. Secondly, the problem of frequency offset. At the receiving end of the system, due to the existence of Doppler frequency offset in the received signal, the frequency mismatch between the transmitting and receiving ends occurs. In a multi-carrier system, the carrier frequency offset (CFO) will destroy the orthogonality between carriers and introduce inter-carrier interference (ICI). Due to the time-varying characteristics of Doppler frequency offset in high mobility scenarios, the accuracy of Doppler estimation and tracking faces new challenges. In high mobility scenarios, designing a new network architecture to meet its characteristics and ensure the performance requirements of communication, how to ensure the reliability and accuracy of fast and frequent switching, and the high penetration loss of signals brought by high-speed railway systems have become urgent problems to be solved in this scenario.

OTFS modulation is a two-dimensional modulation scheme designed in the delay-Doppler domain. It is different from the modulation scheme based on the time-frequency (TF) domain. It converts the dual-dispersion channel into a nearly flat fading channel in the delay-Doppler domain through a series of two-dimensional transformations. In this domain, each symbol in a data frame will experience the same almost unchanged fading, thus having a more significant performance gain than existing modulation schemes. As shown in Figure 1, OTFS modulation is a data modulation symbol generated in the delay-Doppler domain. The conversion of the delay-Doppler domain discrete symbols into a time domain waveform is generally completed in two steps. First, the delay-Doppler domain is converted to the time-frequency domain through the inverse dual Fourier transform (ISFFT, or inverse dual finite Fourier transform), and then converted to the time domain through the Heisenberg transform. At the receiving end, the data is restored by using the inverse operation of the transmitting end. First, the received signal is converted from the time domain to the time-frequency domain through the Wigner transform, and then converted from the time-frequency domain to the delay-Doppler domain through the dual Fourier transform (SFFT, or dual finite Fourier transform). If the Heisenberg transform is specialized into the inverse fast Fourier transform (IFFT) and the Wigner transform is specialized into the fast Fourier transform (FFT), then the inner dotted box is an orthogonal frequency division multiplexing (OFDM) system. Therefore, the OTFS-OFDM system can be regarded as a transmission system that adds a preprocessing module at the transmitting end of the OFDM system and a SFFT module at the receiving end. In this way, the fusion of OTFS and OFDM systems can be achieved.

The above scheme can realize the combination of multi-carrier OTFS and multi-carrier modulation technology. In order to realize the above scheme, the design of the scheduling unit (frame structure) of the OTFS system in the delay-Doppler domain needs to be compatible with the OFDM frame structure. However, the current New Radio (NR) system is based on OFDM modulation and lacks an effective modulation scheme for OTFS.

To this end, this embodiment proposes a communication processing method and device for solving the above technical problems, and determines an effective modulation scheme for OTFS. By performing block ISFFT on the OTFS frame, different OTFS resource blocks are mapped to different sub-bands, and different OTFS resource blocks correspond to different frequencies. This can reduce the complexity of ISFFT and SFFT, and can also combat frequency selective fading channels.

The communication processing method and device provided by the present disclosure are described in detail below with reference to the accompanying drawings.

This embodiment determines an effective modulation scheme for OTFS, by performing block ISFFT on the OTFS frame, mapping different OTFS resource blocks to different sub-bands, and different OTFS resource blocks correspond to different frequencies. This can reduce the complexity of ISFFT and SFFT, and can also combat frequency selective fading channels.

Further, in order to illustrate the specific execution process of the above communication processing system, Figure 3 shows a timing diagram of a communication processing method according to an embodiment of the present disclosure. The method is applied to the above communication processing system, as shown in Figure 3, and may include the following steps:

Step 201: A network device sends first information to a terminal device.

In some embodiments, the terminal device receives first information sent by the network device. The first information can be used to indicate to the terminal device the configuration information of different OTFS resource blocks of an uplink (UL) or downlink (DL) OTFS signal (or OTFS frame) in the delay-Doppler domain. Such configuration information can be the relevant scheduling information that the OTFS signal is divided into multiple OTFS resource blocks in the delay-Doppler domain, and the terminal device can receive or send the OTFS signal according to the scheduling information.

In some embodiments, the first information may be a type of communication information, such as an indication information or a signaling, etc. For example, the first information may include: RRC signaling; and/or MAC CE signaling; and/or DCI signaling. In addition, the first information may also be the configuration information, that is, the network device may directly send the configuration information of different OTFS resource blocks for indicating the uplink or downlink OTFS signal in the delay-Doppler domain to the terminal device, etc.

In this embodiment, the OTFS frame may be divided into blocks to obtain different OTFS resource blocks (ResourceBlock).

For example, as shown in FIG4 , the frame in the delay-Doppler domain is aligned with the frame in the time-frequency domain. Assume that an OTFS frame has M OTFS symbols in the delay domain and N subcarriers in the Doppler domain, where the delay-Doppler domain data symbol is: x[k,l], and the information symbol in the time-frequency domain is: X[n,m]. Then the transformation between the delay-Doppler information symbol and the time-frequency domain information symbol is as follows:

For a frame of size M×N in the delay-Doppler domain, through the dual Fourier transform (SFFT), the frame size in the time-frequency domain is N×M. Correspondingly, for a frame of size N×M in the time-frequency domain, through the inverse dual Fourier transform (ISFFT), the frame size in the delay-Doppler domain is M×N.

According to the method of this embodiment, for the OTFS frame, the delay axis is divided into different resource blocks in the delay-Doppler domain, and the M points ISFFT in the original delay domain are converted into I points. Point ISFFT is performed and then converted to the time-frequency domain (Time-Frequency) corresponding to different sub-bands, where M can represent the number of delay domain OTFS symbols of an OTFS frame, and I can represent the number of blocks of an OTFS frame, which can be an integer greater than or equal to 1.

In some embodiments, the network device first needs to determine the scheduling unit information of the OTFS signal in the delay-Doppler domain in order to accurately perform block segmentation. In some examples, the scheduling unit information may include: the number of OTFS symbols of the OTFS signal in the delay domain; in addition, the scheduling unit information may also include: the number of subcarriers of the OTFS signal in the Doppler domain. The scheduling unit information determined by the network device can be sent to the terminal device, so that the terminal device can receive the OTFS resource block according to the configuration information of different OTFS resource blocks and in combination with the scheduling unit information. There are multiple optional ways for the network device to send the scheduling unit information to the terminal device, such as sending it through the first information, or sending it through the second information, etc. The second information is communication information different from the first information, such as an indication information or a signaling, etc.

The network device can perform block division according to the scheduling unit information to obtain different OTFS resource blocks of the OTFS signal in the delay-Doppler domain, and further determine the number of OTFS resource blocks of the OTFS signal in the delay-Doppler domain.

This embodiment can divide the OTFS frame along the delay axis according to the number of OTFS symbols in the OTFS frame in the delay domain to obtain different OTFS resource blocks. This embodiment does not limit the specific block standard. For example, as shown in Figure 4, after the ISFFT conversion, the M OTFS symbols of the OTFS frame in the delay domain will be mapped to the M frequency bands in the frequency domain. This embodiment divides the OTFS frame into blocks so that the frequency band frequency corresponding to each OTFS resource block after the ISFFT conversion is less than a certain threshold. In this case, it can be considered that the frequency selective fading between different subcarriers in each frequency band is the same, thereby combating the frequency selective fading channel. In addition, since the original M-point ISFFT is converted into I Point ISFFT, correspondingly, the original M point SFFT is converted into I Point SFFT, thus the complexity of ISFFT and SFFT can be effectively reduced, and the conversion efficiency of ISFFT and SFFT can be improved.

In some embodiments, the configuration information may include: at least one type of configuration information.

In some embodiments, the configuration information of different OTFS resource blocks of the OTFS signal in the delay-Doppler domain may include: precoding information corresponding to different OTFS resource blocks respectively. Accordingly, the method of this embodiment also includes: the network device determines the precoding information corresponding to different OTFS resource blocks respectively.

In this embodiment, the network device configures the corresponding precoding information for different OTFS resource blocks of the OTFS signal in the delay-Doppler domain. For example, different frequency band signals will produce different phase shifts after passing through the channel. Generally, the fading of each subcarrier channel in the coherent bandwidth is the same. If the signal bandwidth exceeds the coherent bandwidth, the channel fading of different frequency bands is different. In order to offset this situation, the corresponding precoding information can be configured for these OTFS resource blocks, so that the phase of the signal received by the receiving end for different frequencies is the same.

In some embodiments, the configuration information of different OTFS resource blocks of the OTFS signal in the delay-Doppler domain may include: reference signal information corresponding to different OTFS resource blocks.
