[0085] In recent years, the large-scale development of high-speed railways (HSR) and the increasing popularity of vehicle communication systems on highways have garnered widespread attention for wireless communication systems in high-speed mobility environments. 5G systems aim to provide bursty broadband services to users on trains traveling at speeds up to 500 km / h or in highly mobile vehicles, guaranteeing data rates of up to 150 Mbps. However, most current wireless communication systems can only guarantee high data rates and high-quality services in low- or medium-speed environments, severely limiting their coverage and transmission efficiency in high-speed mobility scenarios.

[0086] The main challenges facing communication systems in high-mobility scenarios include: first, rapid time-varying fading. Increased mobility leads to large Doppler shifts and spreads in communication systems, which severely degrade communication performance. Furthermore, changes in terminal velocity can cause changes in the attenuation coefficient and time-varying Doppler spread. The rapid changes in the wireless transmission environment further complicate channel analysis and modeling. Second, frequency offset. At the receiving end of the system, Doppler offset in the received signal leads to frequency mismatch between the transmitter and receiver. In multi-carrier systems, carrier frequency offset (CFO) destroys the orthogonality between carriers and introduces inter-carrier interference (ICI). The time-varying nature of Doppler offset in high-mobility scenarios poses new challenges to the accuracy of Doppler estimation and tracking. Designing new network architectures to meet these characteristics and ensure communication performance requirements, ensuring the reliability and accuracy of rapid and frequent handoffs, and addressing the high signal penetration loss in high-speed rail systems are all pressing issues that need to be addressed in these scenarios.

[0087] OTFS modulation is a two-dimensional modulation scheme designed in the delay-Doppler domain. Unlike modulation schemes based on the time-frequency (TF) domain, it transforms a 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 experiences the same, nearly constant fading, resulting in significant performance gains over existing modulation schemes. As shown in Figure 1, OTFS modulation generates data modulation symbols in the delay-Doppler domain. The conversion of discrete symbols in the delay-Doppler domain into a time-domain waveform is generally completed in two steps: first, using the inverse dual Fourier transform (ISFFT, or inverse dual finite Fourier transform) to convert from the delay-Doppler domain to the time-frequency domain, and then using the Heisenberg transform to convert back to the time domain. At the receiving end, data is recovered using operations that are inverse to those at the transmitting end. First, the received signal is converted from the time domain to the time-frequency domain using the Wigner transform, and then from the time-frequency domain to the delay-Doppler domain using the dual Fourier transform (SFFT). If the Heisenberg transform is specialized as the inverse fast Fourier transform (IFFT), and the Wigner transform as the fast Fourier transform (FFT), then the inner dashed box represents an orthogonal frequency division multiplexing (OFDM) system. Therefore, the OTFS-OFDM system can be viewed as a transmission system that adds a preprocessing module to the OFDM system's transmitter and an SFFT module to the receiver. This allows for the integration of OTFS and OFDM systems.

[0088] The above solution combines multi-carrier OTFS with multi-carrier modulation technology. To achieve this, the design of the OTFS system's scheduling unit (frame structure) in the delay-Doppler domain must be compatible with the OFDM frame structure. However, current New Radio (NR) systems use OFDM-based modulation and lack effective OTFS modulation schemes.

[0089] To this end, this embodiment proposes a communication processing method and apparatus to address the aforementioned technical issues. This method identifies an effective OTFS modulation scheme. By performing block-wise ISFFT on the OTFS frame, different OTFS resource blocks are mapped to different subbands, with different OTFS resource blocks corresponding to different frequencies. This reduces the complexity of the ISFFT and SFFT operations and provides robustness against frequency-selective fading channels.

[0090] The communication processing method and device provided by the present disclosure are described in detail below with reference to the accompanying drawings.

The network device 11 provided in the embodiments of the present disclosure may be composed of a central unit (CU) and a distributed unit (DU), wherein the CU may also be referred to as a control unit. The CU-DU structure may be used to split the protocol layer of a network device, such as a base station, and the functions of some protocol layers are placed in the CU for centralized control, while the functions of the remaining part or all of the protocol layers are distributed in the DU, and the DU is centrally controlled by the CU.

[0093] In some examples, the terminal device 12 can be called a terminal, user equipment, mobile station (MS), mobile terminal (MT), etc. The terminal device 12 can also be a car with communication functions, a smart car, a mobile phone, a wearable device, a tablet computer (Pad), a computer with wireless transceiver functions, a virtual reality device, an augmented reality device, a wireless terminal device in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, a wireless terminal device in a smart home, etc. The embodiments of the present disclosure do not limit the specific technology and specific device form adopted by the terminal device 12.

The number and form of the entities may be arbitrary. The connection relationship between the entities is illustrative only. The entities may be connected or disconnected, and the connection may be in any manner, whether direct or indirect, and wired or wireless.

[0096] The embodiments of the present disclosure can be applied to satellite communications, Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5GNR, Future Radio Access (FRA), New-Radio Access Technology (RAT), New Radio (NR), New Radio Access (NX), Future generation radio access (FX), Global System for Mobile communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X), systems utilizing other communication methods, and next-generation systems based on and extending these methods. Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0097] In some examples, the network device 11 sends first information to the terminal device 12, the terminal device 12 receives the first information sent by the network device 11, and determines the configuration information of different OTFS resource blocks of the OTFS signal in the delay-Doppler domain based on the first information. The terminal device 12 can send the OTFS signal to the network device 11 based on the configuration information, or receive the OTFS signal from the network device 11.

[0098] This embodiment defines an effective OTFS modulation scheme. By performing block-wise ISFFT on the OTFS frame, different OTFS resource blocks are mapped to different subbands. Different OTFS resource blocks correspond to different frequencies. This reduces the complexity of the ISFFT and SFFT operations and provides robustness against frequency-selective fading channels.

[0099] Furthermore, to illustrate the specific execution process of the above-mentioned communication processing system, FIG3 shows a timing diagram of a communication processing method according to an embodiment of the present disclosure. The method is applied to the above-mentioned communication processing system, as shown in FIG3, and may include the following steps:

[0100] Step 201: The network device sends first information to the terminal device.

[0101] In some embodiments, a terminal device receives first information sent by a network device. The first information may be used to indicate to the terminal device configuration information for different OTFS resource blocks in the delay-Doppler domain for an uplink (UL) or downlink (DL) OTFS signal (or OTFS frame). This configuration information may be scheduling information related to the division of the OTFS signal into multiple OTFS resource blocks in the delay-Doppler domain. The terminal device may receive or transmit the OTFS signal according to this scheduling information.

[0102] In some embodiments, the first information may be a type of communication information, such as an indication information or a signaling, and may include: RRC signaling; and / or MAC CE signaling; and / or DCI signaling. In addition, the first information may also be configuration information, that is, the network device may directly send configuration information for indicating different OTFS resource blocks in the delay-Doppler domain for uplink or downlink OTFS signals to the terminal device, etc.

[0103] In this embodiment, the OTFS frame may be divided into blocks to obtain different OTFS resource blocks (ResourceBlock).

[0104] For example, as shown in Figure 4, the frames in the delay-Doppler domain are aligned with the frames 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. The delay-Doppler domain data symbol is x[k, l], and the time-frequency domain information symbol is X[n, m]. The conversion between the delay-Doppler information symbol and the time-frequency domain information symbol is as follows:

[0105] For a frame of size M×N in the delay-Doppler domain, the frame size in the time-frequency domain is N×M through the dual Fourier transform (SFFT). Correspondingly, for a frame of size N×M in the time-frequency domain, the frame size in the delay-Doppler domain is M×N through the inverse dual Fourier transform (ISFFT).

[0106] Using the method of this embodiment, the OTFS frame is divided into different resource blocks along the delay axis in the delay-Doppler domain, and the M points ISFFT in the original delay domain are converted into I points. The ISFFT is then converted to the time-frequency domain to correspond to different subbands, where M represents the number of delay-domain OTFS symbols in an OTFS frame, and I represents the number of blocks in an OTFS frame, which can be an integer greater than or equal to 1.

[0107] 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 to facilitate the terminal device to receive or send the OTFS signal based on 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.

[0108] 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.

[0109] This embodiment can block 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 blocking 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 blocks the OTFS frame 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, accordingly, the original M point SFFT is converted into I Point SFFT, thus can effectively reduce the complexity of ISFFT and SFFT, and improve the conversion efficiency of ISFFT and SFFT.

[0110] In some embodiments, the configuration information may include: at least one type of configuration information.

[0111] 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. Accordingly, the method of this embodiment further includes: the network device determines the precoding information corresponding to different OTFS resource blocks.

[0112] In this embodiment, the network device configures corresponding precoding information for different OTFS resource blocks of the OTFS signal in the delay-Doppler domain. For example, signals in different frequency bands will produce different phase shifts after passing through the channel. Generally, the channel fading of each subcarrier within the coherence bandwidth is the same. If the signal bandwidth exceeds the coherence bandwidth, the channel fading of different frequency bands will be different. To offset this, the OTFS resource blocks can be configured with corresponding precoding information, so that the phase of the signals received by the receiver at different frequencies is the same.

[0113] 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. Accordingly, the method of this embodiment may also include: the network device determines the reference signal information corresponding to different OTFS resource blocks. In some examples, the reference signal information may include: reference signal position information (or may be called transmission pilot position information); and / or protection symbol information. The reference signal position information may include the position information of the reference signal in the delay-Doppler domain, and the protection symbol information may include the position information of the guard symbols in the delay-Doppler domain, etc., wherein the guard symbols are used to serve as a protection interval between the reference signal transmission position and the data transmission position. Reference signals include but are not limited to: DMRS, CSI-RS, etc. By receiving the first information, the terminal device can determine the reference signal information corresponding to different OTFS resource blocks, and then determine the scheduling information related to the reference signal. For example, as shown in FIG5 , it is an example of a pattern of a reference signal in the delay-Doppler domain. In FIG5 , the “□” at the center position represents the reference signal, which has corresponding delay-Doppler domain coordinates. There are many “○”s around the “□”, where the “○”s represent protection symbols, and “×”s represent data symbols, that is, there is a protection interval between the reference signal transmission position and the data transmission position.

[0114] In some embodiments, the configuration information for different OTFS resource blocks of an OTFS signal in the delay-Doppler domain may include index parameters corresponding to the different OTFS resource blocks. Accordingly, the method of this embodiment may further include: the network device determining the index parameters corresponding to the different OTFS resource blocks. In some examples, the index parameters may include: a position index of the OTFS resource block in the delay domain; and / or the number of OTFS symbols contained in the OTFS resource block in the delay domain.

[0115] The number of OTFS symbols contained in an OTFS resource block in the delay domain can be expressed in various ways. For example, the specific number of OTFS symbols contained in the OTFS resource block in the delay domain can be directly indicated. For another example, if N consecutive symbols are used as a scheduling granularity, the index parameter is based on this scheduling granularity and indicates the number of OTFS symbols contained in the OTFS resource block in the delay domain within this scheduling granularity. For example, if 12 consecutive symbols in the delay domain are used as a scheduling granularity, and the index parameter indicates that the number of OTFS symbols contained in this scheduling granularity in the delay domain is 1, then the actual number of OTFS symbols contained in the OTFS resource block in the delay domain is 12.

[0116] In some embodiments, the configuration information of different OTFS resource blocks for an OTFS signal in the delay-Doppler domain may include: a correspondence between different OTFS resource blocks and subbands in the time-frequency domain. Accordingly, the method of this embodiment may further include: the network device determining the correspondence between different OTFS resource blocks and subbands in the time-frequency domain.

[0117] For example, the network device determines the correspondence between each OTFS resource block in the delay-Doppler domain and the subband in the time-frequency domain, which can be a one-to-one mapping correspondence, and then sends it to the terminal device to facilitate the terminal device to accurately perform signal conversion.

[0118] Based on the contents of the above embodiments, the configuration information of different OTFS resource blocks of the OTFS signal in the delay-Doppler domain may include at least one of the following:

[0119] A. Precoding information corresponding to different OTFS resource blocks; B. Reference signal information corresponding to different OTFS resource blocks; C.

[0120] Step 202: The network device sends an OTFS signal to the terminal device or receives an OTFS signal from the terminal device according to the configuration information.

[0121] In some embodiments, the terminal device receives the OTFS signal sent by the network device or sends the OTFS signal to the network device according to the configuration information of different OTFS resource blocks of the OTFS signal in the delay-Doppler domain, that is, according to the relevant scheduling information.

[0122] This embodiment defines an effective OTFS modulation scheme. By performing block-wise ISFFT on the OTFS frame, different OTFS resource blocks are mapped to different subbands.
