Description

A communication method and related equipment Technical Field

[0001] The present application relates to the field of wireless communications, and in particular to a communication method and related equipment. Background Art

[0002] Wireless communication can be the transmission communication between two or more communication nodes without propagating through conductors or cables. The communication nodes generally include network devices and terminal devices.

[0003] Currently, in wireless communication systems, a communication node acting as a signal sender can subject the original data to be sent to multiple processing processes, including channel coding, modulation, etc.; correspondingly, a communication node acting as a signal receiver can subject the received signal to other processing processes corresponding to these multiple processing processes, including channel decoding, demodulation, etc., to restore the original data (or obtain an estimate of the original data). These processing processes can improve the reliability of data transmission.

[0004] However, in wireless communication systems, how to improve data processing efficiency is a technical problem that needs to be solved urgently.

[0005] Summary of the Invention

[0006] The present application provides a communication method and related equipment for optimizing the data processing process of wireless communication to improve communication efficiency.

[0007] The first aspect of the present application provides a communication method, which is performed by a first communication device, or the method is performed by some components in the first communication device (such as a processor, a chip or a chip system, etc.), or the method can also be implemented by a logic module or software that can realize all or part of the functions of the first communication device. In the first aspect and its possible implementation, the communication method is described as being performed by a first communication device, wherein the first communication device can be a terminal device or a network device. In this method, the first communication device determines first data, and the first data is data obtained after the second data is subjected to a first processing; wherein the second data is preconfigured; and the first communication device sends the first data.

[0008] Based on the above technical solution, the first data transmitted by the first communication device is the data obtained after the second data has been subjected to the first processing, wherein the second data is preconfigured. In other words, the recipient of the first data (e.g., the second communication device) can determine the second data based on the preconfigured method, so that the recipient can perform the second processing corresponding to the first processing on the received first data to obtain an estimate of the second data. Based on the estimated second data and the preconfigured second data, the recipient can optimize the data processing process of the wireless communication to improve communication efficiency.

[0009] In a possible implementation manner of the first aspect, the second data includes dummy coding bits.

[0010] It should be understood that in the traditional data transmission process, the original data transmitted by the sender needs to be converted into information bits (e.g., binary information bits), and then the information bits are sequentially subjected to one or more of encoding, rate matching, scrambling, modulation, layer mapping, precoding, resource element (RE) mapping, digital beam mapping (BF), waveform shaping, digital-to-analog conversion, and analog BF. Correspondingly, after receiving the data, the receiver needs to perform analog BF, analog-to-digital conversion, waveform reception, digital BF, RE demapping, channel equalization, delayer mapping, demodulation, descrambling, derate matching, decoding, etc. to obtain the information bits, and then perform information conversion on the information bits to obtain the original data (or an estimate of the original data).

[0011] Optionally, the waveforms involved in waveform shaping and waveform reception may include one or more of an orthogonal frequency division multiplexing (OFDM) waveform based on inverse fast Fourier transform (IFFT), a discrete Fourier transform-spread-orthogonal frequency division multiplexing (DFT-s-OFDM) based on fast Fourier transform (FFT) and IFFT, or frequency domain spectrum shaping (FDSS).

[0012] It should be noted that the virtual coding bit can be a bit after coding processing, that is, the virtual coding bit is a bit (for example, a bit to be modulated) that undergoes other processing after the coding processing in one or more of the above-mentioned sending processes. In other words, the virtual coding bit can refer to a bit that has not undergone (or does not need to undergo) coding processing, wherein the virtual coding bit can be called a pseudo-coding bit.

[0013] Based on the above technical solution, the first data is the data obtained after the second data is processed by the first processing, and the second data includes virtual coding bits, wherein the virtual coding bits do not need to undergo coding processing and related processing (such as possible processing before the coding processing, including information conversion processing), that is, the first processing may not include coding processing and related processing. Thus, through the pre-configured virtual coding bits, the first communication device can omit or not perform coding processing and related processing, thereby reducing the processing complexity and delay of the sender. In addition, through the pre-configured virtual coding bits, the receiver of the first data (such as the second communication device) can also omit or not perform the decoding processing corresponding to the coding processing in the process of the receiver performing the second processing corresponding to the first processing on the first data after receiving the first data, thereby reducing the processing complexity and delay of the receiver.

[0014] Optionally, the number of the virtual coding bits is associated with at least one of: a configured number of resource elements (REs), a configured modulation order, and a configured number of streams.

[0015] Optionally, the virtual coding bits are generated based on a first sequence; the first sequence is a configured sequence; or, the first sequence is a sequence determined based on the frame number of the configured time domain resources and / or the configured number of streams; or, the first sequence is determined based on at least one item of resource information among the configured time domain resources, frequency domain resources and spatial domain resources.

[0016] In a possible implementation manner of the first aspect, the second data includes virtual information bits.

[0017] It should be noted that the virtual information bit can be a bit after information conversion processing, that is, the virtual information bit is a bit to be subjected to one or more of the above-mentioned sending processes (for example, a bit to be encoded). In other words, the virtual information bit can refer to a bit that has not undergone (or does not need to undergo) information conversion processing, wherein the virtual information bit can be called a pseudo-information bit.

[0018] Based on the above technical solution, the first data is the data obtained after the second data undergoes the first processing, and the second data includes virtual information bits, wherein the virtual information bits do not need to undergo information conversion processing, that is, the first processing may not include information conversion processing. Thus, through the pre-configured virtual information bits, the first communication device can omit or not perform information conversion processing, thereby reducing the processing complexity and delay of the sender. In addition, through the pre-configured virtual information bits, after receiving the first data, the receiver of the first data (such as the second communication device) can also omit or not perform the inverse processing corresponding to the information conversion processing during the process of the receiver performing the second processing corresponding to the first processing on the first data, thereby reducing the processing complexity and delay of the receiver.

[0019] In a possible implementation manner of the first aspect, the second data includes virtual modulation symbols.

[0020] It should be noted that the virtual modulation symbol can be a signal after modulation processing, that is, the virtual modulation symbol is a signal that has undergone other processing processes after the modulation processing in one or more of the above-mentioned transmission processes (for example, a signal to be RE mapped). In other words, the virtual modulation symbol can refer to a symbol that has not undergone (or does not need to undergo) modulation processing, wherein the virtual modulation symbol can be called a pseudo-modulation symbol.

[0021] Based on the above technical solution, the first data is the data obtained after the second data undergoes the first processing, and the second data includes a virtual modulation symbol, wherein the virtual modulation symbol does not need to undergo modulation processing and related processing (such as possible processing before the modulation processing, including encoding processing), that is, the first processing may not include modulation processing and related processing. Thus, through the pre-configured virtual modulation symbols, the first communication device can omit or not perform modulation processing and related processing, thereby reducing the processing complexity and delay of the sender. In addition, through the pre-configured virtual modulation symbols, after receiving the first data, the receiver of the first data (such as the second communication device) can also omit or not perform the demodulation processing corresponding to the modulation processing in the process of the receiver performing the second processing corresponding to the first processing on the first data, thereby reducing the processing complexity and delay of the receiver.

[0022] Optionally, the number of virtual modulation symbols is associated with at least one of the number of configured REs and the number of configured streams.

[0023] Optionally, the virtual modulation symbol is a preset symbol sequence or a symbol determined by a random sequence.

[0024] In a possible implementation manner of the first aspect, the second data includes a virtual transmission signal.

[0025] It should be noted that the virtual transmission signal can be a signal sent after waveform shaping processing, that is, the virtual transmission signal is a signal that undergoes other processing processes after the waveform shaping processing in one or more of the above-mentioned transmission processes (for example, a signal to be carrier modulated). In other words, the virtual transmission signal can refer to a signal that has not undergone (or does not need to undergo) waveform shaping processing, wherein the virtual transmission signal can be called a pseudo transmission signal.

Thus, through the pre-configured virtual transmission signal, the first communication device can omit or not perform waveform shaping processing and related processing, thereby reducing the processing complexity and delay of the sender. In addition, through the pre-configured virtual transmission signal, the receiver of the first data (for example, the second communication device) can also omit or not perform the waveform receiving processing corresponding to the waveform shaping processing during the process of the receiver performing the second processing corresponding to the first processing on the first data after receiving the first data, thereby reducing the processing complexity and delay of the receiver.

[0027] Optionally, the transmitted signal is a random signal sequence, a preconfigured signal sequence, a constant power signal or a random signal.

In other words, the recipient of the first data (e.g., the second communication device) can perform a second process corresponding to the first process on the received first data to obtain an estimate of the second data, and then optimize the first neural network based on the estimated second data and the preconfigured second data.

[0030] It should be understood that the process of optimizing the first neural network may include one or more of training the first neural network, evaluating the first neural network, testing the first neural network, validating the first neural network, or calibrating the first neural network.

[0032] Optionally, when the first processing does not include part of the at least one item mentioned above, the processing of the part of the item may be omitted or not performed, thereby reducing processing complexity and delay.

[0033] Based on the above technical solution, in a traditional signal transmitter, the first processing can be performed by a corresponding device. For example, the encoding processing included in the first processing can be implemented by an encoder, and the modulation processing can be implemented by a modulator. In the above technical solution, at least one item included in the first processing can be implemented by a neural network. The first neural network can include a neural network deployed in the first communication device, and the neural network deployed in the first communication device is used for the first processing.

[0037] Optionally, when the second processing does not include part of the at least one item mentioned above, the processing of the part of the items may be omitted or not performed, thereby reducing processing complexity and delay.

[0039] It should be noted that the second processing corresponding to the first processing can be understood as the inverse of the first processing. For example, if the first processing includes encoding, the second processing corresponding to the first processing may include decoding. For another example, if the first processing includes modulation, the second processing corresponding to the first processing may include demodulation.

[0040] In a possible implementation of the first aspect, the method also includes: the first communication device sends third data, and the third data is data obtained after the second data is processed by the first processing; wherein, the signal power of the first data is different from the signal power of the third data, and / or the modulation order of the first data is different from the modulation order of the third data.

[0148] First, some of the terms used in the embodiments of the present application are explained to facilitate understanding by those skilled in the art.

[0149] (1) Terminal device: It can be a wireless terminal device that can receive network device scheduling and instruction information. The wireless terminal device can be a device that provides voice and / or data connectivity to the user, or a handheld device with wireless connection function, or other processing device connected to a wireless modem.

[0150] Terminal devices can communicate with one or more core networks or the Internet via a radio access network (RAN). Terminal devices can be mobile terminal devices, such as mobile phones (also known as "cellular" phones, mobile phones), computers, and data cards. For example, they can be portable, pocket-sized, handheld, computer-built-in, or vehicle-mounted mobile devices that exchange voice and / or data with the radio access network. Examples include personal communication service (PCS) phones, cordless phones, Session Initiation Protocol (SIP) phones, wireless local loop (WLL) stations, personal digital assistants (PDAs), tablet computers, and computers with wireless transceiver capabilities. Wireless terminal equipment can also be called system, subscriber unit, subscriber station, mobile station, mobile station (MS), remote station, access point (AP), remote terminal equipment (remote terminal), access terminal equipment (access terminal), user terminal equipment (user terminal), user agent, subscriber station (SS), customer premises equipment (CPE), terminal, user equipment (UE), mobile terminal (MT), etc.

[0151] As an example and not a limitation, in the embodiments of the present application, the terminal device may also be a wearable device. Wearable devices may also be referred to as wearable smart devices or smart wearable devices, etc., which are a general term for wearable devices that are intelligently designed and developed using wearable technology for daily wear, such as glasses, gloves, watches, clothing, and shoes. A wearable device is a portable device that is worn directly on the body or integrated into the user's clothes or accessories. Wearable devices are not only hardware devices, but also achieve powerful functions through software support, data interaction, and cloud interaction. Broadly speaking, wearable smart devices include those that are fully functional, large in size, and can achieve complete or partial functions without relying on smartphones, such as smart watches or smart glasses, etc., as well as those that only focus on a certain type of application function and need to be used in conjunction with other devices such as smartphones, such as various smart bracelets, smart helmets, and smart jewelry for vital sign monitoring.

[0152] The terminal may also be a drone, a robot, a terminal in device-to-device (D2D) communication, a terminal in vehicle-to-everything (V2X), a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal in industrial control, a wireless terminal in self-driving, a wireless terminal in remote medical, a wireless terminal in smart grid, a wireless terminal in transportation safety, a wireless terminal in smart city, a wireless terminal in smart home, etc.

[0153] In addition, the terminal device may also be a terminal device in a communication system that has evolved after the fifth generation (5G) communication system (e.g., a sixth generation (6G) communication system) or a terminal device in a future public land mobile network (PLMN). For example, the 6G network can further expand the form and function of 5G communication terminals. 6G terminals include but are not limited to vehicles, cellular network terminals (with integrated satellite terminal functions), drones, and Internet of Things (IoT) devices.

[0154] In an embodiment of the present application, the terminal device may also obtain AI services provided by the network device. Optionally, the terminal device may also have AI processing capabilities.

[0155] (2) Network equipment: It can be a device in a wireless network. For example, the network equipment can be a RAN node (or device) that connects a terminal device to a wireless network, which can also be called a base station. Currently, some examples of RAN equipment include: base station, evolved NodeB (eNodeB), gNB (gNodeB) in a 5G communication system, transmission reception point (TRP), evolved Node B (eNB), radio network controller (RNC), Node B (NB), home base station (e.g., home evolved Node B, or home Node B, HNB), base band unit (BBU), or wireless fidelity (Wi-Fi) access point AP, etc. In addition, in a network structure, the network equipment can include a centralized unit (CU) node, a distributed unit (DU) node, or a RAN device including a CU node and a DU node.

[0156] Alternatively, a RAN node can be a macro base station, micro base station, indoor base station, relay node, donor node, or a wireless controller in a cloud radio access network (CRAN) scenario. A RAN node can also be a server, wearable device, vehicle, or vehicle-mounted device. For example, the access network device in vehicle-to-everything (V2X) technology can be a roadside unit (RSU).

[0157] In another possible scenario, multiple RAN nodes collaborate to assist the terminal in achieving wireless access, and different RAN nodes respectively implement part of the functions of the base station. For example, the RAN node can be a centralized unit (CU), a distributed unit (DU), a CU-control plane (CP), a CU-user plane (UP), or a radio unit (RU). The CU and DU can be set separately, or they can be included in the same network element, such as a baseband unit (BBU). The RU can be included in a radio frequency device or radio frequency unit, such as a remote radio unit (RRU), an active antenna unit (AAU), or a remote radio head (RRH).

[0158] In different systems, CU (or CU-CP and CU-UP), DU or RU may also have different names, but those skilled in the art can understand their meanings. For example, in an open access network (open RAN, O-RAN or ORAN) system, CU may also be called O-CU (open CU), DU may also be called O-DU, CU-CP may also be called O-CU-CP, CU-UP may also be called O-CU-UP, and RU may also be called O-RU. For the convenience of description, this application takes CU, CU-CP, CU-UP, DU and RU as examples for description. Any unit of CU (or CU-CP, CU-UP), DU and RU in this application can be implemented by a software module, a hardware module, or a combination of a software module and a hardware module.

[0159] The communication between the access network device and the terminal device follows a certain protocol layer structure. The protocol layer may include a control plane protocol layer and a user plane protocol layer. The control plane protocol layer may include at least one of the following: a radio resource control (RRC) layer, a packet data convergence protocol (PDCP) layer, a radio link control (RLC) layer, a media access control (MAC) layer, or a physical (PHY) layer. The user plane protocol layer may include at least one of the following: a service data adaptation protocol (SDAP) layer, a PDCP layer, an RLC layer, a MAC layer, or a physical layer.

[0160] For the correspondence between network elements in the ORAN system and their achievable protocol layer functions, please refer to Table 1 below.

[0161] Table 1

[0162] The network device may be any other device that provides wireless communication functionality to the terminal device. The embodiments of this application do not limit the specific technology and device form used by the network device. For ease of description, the embodiments of this application do not limit this.

[0163] The network equipment may also include core network equipment, which may include, for example, a mobility management entity (MME), a home subscriber server (HSS), a serving gateway (S-GW), a policy and charging rules function (PCRF), and a public data network gateway (PDN gateway, P-GW) in a fourth generation (4G) network; and network elements such as an access and mobility management function (AMF), a user plane function (UPF), or a session management function (SMF) in a 5G network. In addition, the core network equipment may also include other core network equipment in a 5G network and a next generation network of a 5G network.

[0164] In an embodiment of the present application, the above-mentioned network device may also have a network node with AI capabilities, which can provide AI services for terminals or other network devices. For example, it can be an AI node on the network side (access network or core network), a computing power node, a RAN node with AI capabilities, a core network element with AI capabilities, etc.

[0165] In the embodiments of the present application, the apparatus for implementing the function of the network device may be the network device, or may be a device capable of supporting the network device in implementing the function, such as a chip system, which may be installed in the network device. In the technical solutions provided in the embodiments of the present application, the technical solutions provided in the embodiments of the present application are described by taking the network device as an example.

[0166] (3) Configuration and pre-configuration: In this application, configuration and pre-configuration are used simultaneously. Configuration refers to the network device / server sending some parameter configuration information or parameter values ​​to the terminal through messages or signaling, so that the terminal can determine the communication parameters or resources during transmission based on these values ​​or information. Pre-configuration is similar to configuration, and can be parameter information or parameter values ​​pre-negotiated between the network device / server and the terminal device, or parameter information or parameter values ​​used by the base station / network device or terminal device as specified in the standard protocol, or parameter information or parameter values ​​pre-stored in the base station / server or terminal device. This application does not limit this.

[0167] Furthermore, these values ​​and parameters can be changed or updated.

[0168] (4) The terms "system" and "network" in the embodiments of the present application can be used interchangeably. "Multiple" refers to two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships can exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone, where A and B can be singular or plural. The character " / " generally indicates that the previous and next associated objects are in an "or" relationship. "At least one of the following" or similar expressions refers to any combination of these items, including any combination of single or plural items. For example, "at least one of A, B and C" includes A, B, C, AB, AC, BC or ABC. In addition, unless otherwise specified, the ordinal numbers such as "first" and "second" mentioned in the embodiments of the present application are used to distinguish multiple objects, and are not used to limit the order, timing, priority or importance of multiple objects.

[0169] (5) “Sending” and “receiving” in the embodiments of the present application indicate the direction of signal transmission. For example, “sending information to XX” can be understood as the destination of the information being XX, which can include direct sending through the air interface, as well as indirect sending through the air interface by other units or modules. “Receiving information from YY” can be understood as the source of the information being YY, which can include direct receiving from YY through the air interface, as well as indirect receiving from YY through the air interface from other units or modules. “Sending” can also be understood as the “output” of the chip interface, and “receiving” can also be understood as the “input” of the chip interface.

[0170] In other words, sending and receiving can be performed between devices, for example, between a network device and a terminal device, or can be performed within a device, for example, sending or receiving between components, modules, chips, software modules or hardware modules within the device through a bus, wiring or interface.

[0171] It is understandable that information may be processed between the source and destination of information transmission, such as coding, modulation, etc., but the destination can understand the valid information from the source. Similar expressions in this application can be understood similarly and will not be repeated.

[0172] (6) In the embodiments of the present application, "indication" may include direct indication and indirect indication, and may also include explicit indication and implicit indication. The information indicated by a certain information (such as the indication information described below) is called information to be indicated. In the specific implementation process, there are many ways to indicate the information to be indicated, such as but not limited to, directly indicating the information to be indicated, such as the information to be indicated itself or the index of the information to be indicated. The information to be indicated may also be indirectly indicated by indicating other information, wherein the other information is associated with the information to be indicated; or only a part of the information to be indicated may be indicated, while the other part of the information to be indicated is known or agreed in advance. For example, the indication of specific information may be achieved by means of the arrangement order of each information agreed in advance (such as predefined by the protocol), thereby reducing the indication overhead to a certain extent. The present application does not limit the specific method of indication. It is understandable that for the sender of the indication information, the indication information can be used to indicate the information to be indicated, and for the receiver of the indication information, the indication information can be used to determine the information to be indicated.

[0173] In this application, unless otherwise specified, the same or similar parts between the various embodiments can refer to each other. In the various embodiments of this application, and the various methods / designs / implementations in each embodiment, if there is no special explanation and logical conflict, the terms and / or descriptions between different embodiments and the various methods / designs / implementations in each embodiment are consistent and can be referenced to each other. The technical features in different embodiments and the various methods / designs / implementations in each embodiment can be combined to form new embodiments, methods, or implementations according to their inherent logical relationships. The following description of the implementation methods of this application does not constitute a limitation on the scope of protection of this application.

[0174] The present application can be applied to a long term evolution (LTE) system, a new radio (NR) system, or a communication system evolved after 5G (such as 6G, etc.). The communication system includes at least one network device and / or at least one terminal device.

[0175] Please refer to Figure 1a, which is a schematic diagram of a communication system in this application. Figure 1a exemplarily illustrates a network device and six terminal devices, namely terminal device 1, terminal device 2, terminal device 3, terminal device 4, terminal device 5, and terminal device 6. In the example shown in Figure 1a, terminal device 1 is a smart teacup, terminal device 2 is a smart air conditioner, terminal device 3 is a smart gas pump, terminal device 4 is a vehicle, terminal device 5 is a mobile phone, and terminal device 6 is a printer.

[0176] As shown in Figure 1a, the AI ​​configuration information sending entity can be a network device. The AI ​​configuration information receiving entity can be terminal devices 1-6. In this case, the network device and terminal devices 1-6 form a communication system. In this communication system, terminal devices 1-6 can send data to the network device, and the network device needs to receive data sent by terminal devices 1-6. At the same time, the network device can send configuration information to terminal devices 1-6.

[0177] For example, in Figure 1a, terminal devices 4 and 6 can also form a communication system. Terminal device 5 serves as a network device, i.e., the AI ​​configuration information sending entity; terminal devices 4 and 6 serve as terminal devices, i.e., the AI ​​configuration information receiving entities. For example, in a connected vehicle system, terminal device 5 sends AI configuration information to terminal devices 4 and 6, respectively, and receives data from them. Correspondingly, terminal devices 4 and 6 receive AI configuration information from terminal device 5 and send data to terminal device 5.

[0178] Taking the communication system shown in Figure 1a as an example, in addition to performing communication-related services, different devices (including between network devices and network devices, between network devices and terminal devices, and / or between terminal devices) may also perform AI-related services. For example, as shown in Figure 1b, taking the network device as a base station as an example, the base station can perform communication-related services and AI-related services with one or more terminal devices, and different terminal devices can also perform communication-related services and AI-related services. For another example, as shown in Figure 1c, taking the terminal devices including a TV and a mobile phone as an example, communication-related services and AI-related services can also be performed between the TV and the mobile phone.

[0179] The technical solution provided in this application can be applied to a wireless communication system (e.g., the system shown in FIG. 1a , FIG. 1b , or FIG. 1c ). For example, an AI network element can be introduced into the communication system provided in this application to implement some or all AI-related operations. The AI ​​network element can also be referred to as an AI node, AI device, AI entity, AI module, AI model, or AI unit, etc. The AI ​​network element can be a network element built into the communication system. For example, the AI ​​network element can be an AI module built into: an access network device, a core network device, a cloud server, or a network management (OAM) to implement AI-related functions. The OAM can be a network management device for a core network device and / or a network management device for an access network device. Alternatively, the AI ​​network element can also be an independently set network element in the communication system. Optionally, the terminal or the chip built into the terminal can also include an AI entity to implement AI-related functions.

[0180] Currently, in wireless communication systems (such as those shown in Figures 1a, 1b, or 1c), a communication node, acting as a signal transmitter, can process the original data to be transmitted through multiple processing steps, including channel coding and modulation. Correspondingly, a communication node, acting as a signal receiver, can process the received signal through other processing steps corresponding to these multiple processing steps, including channel decoding and demodulation, to recover the original data (or obtain an estimate of the original data). These processing steps can improve the reliability of data transmission. However, in wireless communication systems, improving data processing efficiency is a technical problem that needs to be solved urgently.

[0181] To address the above-mentioned issues, the present application provides a communication method and related devices for optimizing the data processing process of wireless communications to improve communication efficiency. A detailed description will be given below with reference to the accompanying drawings.

[0182] Please refer to FIG2 , which is a schematic diagram of an implementation of the communication method provided in this application. The method includes the following steps.

[0183] It should be noted that, in FIG2 , the method is illustrated by taking the first communication device and the second communication device as the execution subjects of the interaction diagram as an example, but the present application does not limit the execution subjects of the interaction diagram. For example, the execution subject of S201 in FIG2 and the corresponding implementation method is the first communication device, and the execution subject may also be a chip, chip system, or processor that supports the first communication device to implement the method, or a logic module or software that can implement all or part of the functions of the first communication device. The second communication device in S201-S202 in FIG2 and the corresponding implementation method may also be replaced by a chip, chip system, or processor that supports the second communication device to implement the method, or may be replaced by a logic module or software that can implement all or part of the functions of the second communication device.

[0184] S201. A first communication device sends first data, and correspondingly, a second communication device receives the first data, wherein the first data is data obtained after a first processing of the second data, and the second data is pre-configured.

[0185] S202. The second communication device performs a second process corresponding to the first process on the first data.

[0186] In one possible implementation, the first data and preconfigured second data sent by the first communication device in step S201 are used in a first neural network, and the first neural network is associated with the first process. Specifically, a recipient of the first data (e.g., a second communication device) can perform a second process corresponding to the first process based on the received first data to obtain an estimate of the second data, and optimize the first neural network based on the estimate of the second data and the preconfigured second data.

[0187] It should be understood that the process of optimizing the first neural network may include one or more of training the first neural network, evaluating the first neural network, testing the first neural network, validating the first neural network, or calibrating the first neural network. Furthermore, the first neural network may be implemented in a variety of ways, which will be described below with reference to some implementation examples.

[0188] In a first implementation, the first neural network includes a neural network deployed on a first communication device. Accordingly, in the first implementation, the first neural network is associated with the first processing, including: the neural network deployed on the first communication device is used for the first processing. Taking FIG3 as an example, the first communication device acts as a sender of first data, and the first processing includes at least one of the following items involved in the signal transmission process: coding, rate matching, scrambling, modulation, layer mapping, precoding, RE mapping, digital BF, waveform shaping, digital-to-analog conversion, and analog BF.

[0189] Optionally, in addition to at least one of the above items shown in FIG. 3 , the first processing may also include other processing, such as filtering, power amplification, peak clipping, and the like.

[0190] Optionally, when the first processing does not include part of the at least one item mentioned above, the processing of the part of the item may be omitted or not performed, thereby reducing processing complexity and delay.

[0191] Specifically, in a traditional signal transmitter, the first processing can be performed by a corresponding device. For example, the encoding processing included in the first processing can be implemented by an encoder, and the modulation processing can be implemented by a modulator. In the above technical solution, at least one item included in the first processing can be implemented by a neural network. In implementation method one, the first neural network can include a neural network deployed in the first communication device, and the neural network deployed in the first communication device is used for the first processing. In other words, the receiver of the first data can perform the second processing corresponding to the first processing based on the received first data to obtain an estimate of the second data, and optimize the neural network deployed in the first communication device based on the estimate of the second data and the pre-configured second data to optimize the transmitter implemented based on the neural network.

[0192] Optionally, when the first neural network may include a neural network deployed on a first communication device, the method further includes: the first communication device receiving indication information indicating a gradient of the first neural network. Specifically, the recipient of the first data can send indication information indicating the gradient of the first neural network based on an estimate of the second data and pre-configured second data, so that the first communication device can optimize the first neural network based on the gradient indicated by the indication information.

[0193] In a second implementation, the first neural network unit includes a neural network deployed on a second communication device. Accordingly, in the second implementation, the first neural network associated with the first processing includes: the neural network deployed on the second communication device is used for a second processing corresponding to the first processing. Taking Figure 3 as an example, the second communication device acts as the receiver of the first data, and the second processing includes at least one of the following involved in the signal reception process: analog BF, analog-to-digital conversion, waveform reception, digital BF, RE demapping, channel equalization, de-layer mapping, demodulation, descrambling, rate dematching, and decoding.

[0194] Optionally, in addition to at least one of the above items shown in FIG. 3 , the second processing may also include other processing, such as filtering, peak clipping, and the like.

[0195] Optionally, when the second processing does not include part of the at least one item mentioned above, the processing of the part of the items may be omitted or not performed, thereby reducing processing complexity and delay.

[0196] Specifically, in a traditional signal receiver, the second processing corresponding to the first processing can be performed by a corresponding device. For example, the decoding processing included in the second processing can be implemented by a decoder, and the demodulation processing can be implemented by a demodulator. In the above technical solution, at least one item included in the second processing can be implemented by a neural network. In the second implementation method, the first neural network may include a neural network deployed in the second communication device, and the neural network deployed in the second communication device is used for the second processing corresponding to the first processing. In other words, the receiver of the first data can perform the second processing corresponding to the first processing based on the received first data to obtain an estimate of the second data, and optimize the neural network deployed in the second communication device based on the estimate of the second data and the pre-configured second data to optimize the receiver implemented based on the neural network.

[0197] It should be noted that the second processing corresponding to the first processing can be understood as the inverse of the first processing. For example, if the first processing includes encoding, the second processing corresponding to the first processing may include decoding. For another example, if the first processing includes modulation, the second processing corresponding to the first processing may include demodulation.

[0198] Optionally, the second processing includes the inverse processing of the first processing. However, this does not mean that the processing included in the first processing of the transmitter corresponds one-to-one to the processing included in the second processing of the receiver. This is because the neural network deployed in the first communication device may include a combination of one or more items of the first processing. Similarly, the neural network deployed in the second communication device may include a combination of one or more items of the second processing. For example, the first processing in the first communication device may include modulation processing, and the neural network deployed in the second communication device may simultaneously implement channel equalization and demodulation processing. In this case, the "demodulation processing corresponding to the modulation processing" in the second communication device can be implemented by the neural network. For this reason, the second processing in the second communication device does not necessarily have a clear module for the inverse processing of the corresponding modulation processing.

[0199] In a third implementation, the first neural network includes a neural network deployed on the first communication device and a neural network deployed on the second communication device. In other words, through the aforementioned first data transmission and reception process, optimization of the neural network deployed on the first communication device and the neural network deployed on the second communication device can be achieved, thereby simultaneously optimizing the transmitter and receiver implemented based on the neural networks.

[0200] It should be noted that, in implementation method three, the implementation method in which the first neural network includes a neural network deployed in the first communication device can refer to the implementation process of the above-mentioned implementation method one, and the implementation method in which the first neural network includes a neural network deployed in the second communication device can refer to the implementation process of the above-mentioned implementation method two.

[0201] It can be seen from the above implementation process that some of the devices used for data processing in the signal transmitter and signal receiver can be implemented by neural networks. In this case, the signal transmitter and signal receiver implemented based on the neural network can be optimized according to the scenario through data-driven training, while improving data processing efficiency, it can also achieve better signal transmission design and receiving performance. In other words, the signal transmitter and signal receiver can optimize the neural network in the signal transmitter and / or signal receiver (such as training / evaluation / testing / verification / calibration, etc.) based on the one or more data as processing samples of the neural network through the process of sending and receiving one or more data.

[0202] In addition, in the traditional signal transmission and reception process, as shown in Figure 3, during the signal transmission process, the information transmitted by the transmitter needs to be converted into information bits (e.g., binary information bits), and the information bits are then sent after undergoing the processing corresponding to the signal transmission process in Figure 3. Correspondingly, after receiving the data, the receiver needs to perform the processing corresponding to the signal reception process in Figure 3 to obtain the information bits, and then undergo information conversion to obtain the original data (or an estimate of the original data). When some of the devices used for data processing in the signal transmitter or signal receiver are implemented by a neural network, if one or more data serving as processing samples of the neural network still undergo all the processing in the signal transmission process shown in Figure 3 and all the processing in the signal reception process shown in Figure 3, unnecessary processing complexity and delay will be caused. For example, in the transmitter, when the modulator used for modulation processing in the signal transmission process is replaced by a neural network, the one or more data sent by the transmitter as processing samples are mainly used to optimize the neural network serving as the modulator; in the signal transmission process shown in Figure 3, the encoding processing, rate matching processing, scrambling processing, etc. performed on the one or more data will be unnecessary processing. To this end, in the above technical solution, the pre-configured second data can be implemented in a variety of ways, which will be described below in conjunction with some specific implementation methods.

[0203] Method 1: The second data includes dummy coding bits.

[0204] It should be noted that the virtual coding bit can be a bit after coding processing, that is, the virtual coding bit is a bit (for example, a bit to be modulated) that undergoes other processing after the coding processing in one or more of the above-mentioned sending processes. In other words, the virtual coding bit can refer to a bit that has not undergone (or does not need to undergo) coding processing, wherein the virtual coding bit can be called a pseudo-coding bit.

[0205] In method 1, the first data is the data obtained after the second data undergoes the first processing, and the second data includes virtual coding bits, wherein the virtual coding bits do not need to undergo coding processing and related processing (such as processing that may exist before the coding processing, including information conversion processing), that is, the first processing may not include coding processing and related processing. Thus, through the pre-configured virtual coding bits, the first communication device can omit or not perform coding processing and related processing, thereby reducing the processing complexity and delay of the sender. In addition, through the pre-configured virtual coding bits, the receiver of the first data (such as the second communication device) can also omit or not perform the decoding processing corresponding to the coding processing in the process of the receiver performing the second processing corresponding to the first processing on the first data after receiving the first data, thereby reducing the processing complexity and delay of the receiver.

[0206] Optionally, the number of dummy coding bits is associated with at least one of the number of configured resource elements (REs), the configured modulation order, and the configured number of streams. Exemplarily, the number of dummy coding bits may be determined by the configured number of resources n_re, the modulation order n_mod, and the number of streams n_ss. For example, the number of dummy coding bits n_bit satisfies the following equation: n_bit = n_re*n_mod*n_ss.

[0207] Optionally, the virtual coding bits are generated based on a first sequence; the first sequence is a configured sequence; or, the first sequence is a sequence determined based on the frame number of the configured time domain resources and / or the configured number of streams; or, the first sequence is determined based on at least one item of resource information among the configured time domain resources, frequency domain resources and spatial domain resources.

[0208] In an implementation example, taking the first sequence as a sequence determined based on the frame number and / or the number of configured streams of the configured time domain resources as an example, the first sequence can be called a pseudo-random sequence, and the initial value of the pseudo-random sequence can be determined by the frame number or the number of streams, so as to achieve different random bits generated for different frames and different streams. For example, the pseudo-random (PN) sequence can be generated based on a linear feedback shift register (LFSR), c init Used to initialize registers, where c init Satisfies: c init =n RNTI *2 15 +n init *2 12 +n ss *2 10 +n f ;

[0209] where cinit is the initial value of the pseudo-random sequence register, n RNTI is the RNTI of the user or cell, n init is the initial value (e.g. the initial value of the configuration), n ss is the index of the data stream, n f is the frame number of the current transmission.

[0210] In another implementation example, the first sequence is determined based on at least one resource information item among the configured time domain resources, frequency domain resources, and spatial domain resources. For example, the first sequence satisfies: B = (i% K) 2;

[0211] B is the bit of the binary representation of the first sequence, i is a resource-related integer, (i%K)2 represents the binary representation of the result of i modulo K, Indicates the number of symbols in each time slot, Indicates the time slot number in a frame when the subcarrier spacing is configured as u, l is the symbol index, Indicates the number of resources in a resource block, n rb Indicates the resource block number, k is the frequency domain subcarrier index, n ss Indicates the spatial stream number, n init Indicates an initial value (such as the initial value of a configuration).

[0212] Optionally, B may be generated in bits or bytes. For example, when B is generated in bytes, the value of K satisfies K=2^8, or the value of K satisfies K=2^n_mod (n_mod indicates the modulation order).

[0213] For example, the first neural network includes a neural network deployed at a transmitter (e.g., a first communication device). The processing involved in the signal transmission process of the first communication device includes the process shown in Figure 4a, such as channel coding / interleaving (which can be used to perform the coding, rate matching, and scrambling processing in Figure 3), modulation based on an autoencoder neural network (AE-NN) (which can be used to perform the modulation processing in Figure 3), mapping (which can be used to perform layer mapping, precoding, RE mapping, and digital BF processing in Figure 3), waveform (which can be used to perform waveform shaping processing in Figure 3), and time domain neural network (T-NN) (or time neural network (T-NN)) processing (for example, TNN can include filtering, peak clipping, etc.) as an example. In method 1, when the second data includes a virtual coded bit, the virtual coded bit can be defined as a bit to be modulated, that is, a bit after channel coding processing in traditional data transmission. The virtual coded bit is a bit generated according to an agreed rule, and the transmitting and receiving ends can generate the same bit according to the same rule, so that it can be used for training, evaluation, testing, verification, or calibration of an intelligent air interface neural network. As shown in Figure 4a, the dummy coding bits can be generated before the AE-NN in Figure 4a (i.e., channel coding / interleaving is not required to reduce complexity and latency). The first communication device can modulate the second data containing the dummy coding bits and process it in subsequent modules to obtain first data, and transmit the first data in step S201. This processing flow, as shown in Figure 4a, can be used for training, evaluation, testing, verification, or calibration of neural networks, including modulation and subsequent precoding, waveform, and other modules.

[0214] Optionally, in method one, when the neural network of the deployed first communication device includes AE-NN, the second data may include information bits in addition to virtual coding bits. The difference from the processing of virtual coding bits is that the information bits may also undergo channel coding / interleaving processing before being input into AE-NN.

[0215] Method 2: The second data includes virtual information bits.

[0216] It should be noted that the virtual information bit can be a bit after information conversion processing, that is, the virtual information bit is a bit to be subjected to one or more of the above-mentioned sending processes (for example, a bit to be encoded). In other words, the virtual information bit can refer to a bit that has not undergone (or does not need to undergo) information conversion processing, wherein the virtual information bit can be called a pseudo-information bit.

[0217] In the second method, the first data is the data obtained after the second data is processed by the first processing, and the second data includes virtual information bits, wherein the virtual information bits do not need to undergo information conversion processing, that is, the first processing may not include information conversion processing. Thus, through the pre-configured virtual information bits, the first communication device can omit or not perform information conversion processing, thereby reducing the processing complexity and delay of the sender. In addition, through the pre-configured virtual information bits, after receiving the first data, the receiver of the first data (such as the second communication device) can also omit or not perform the inverse processing corresponding to the information conversion processing during the process of the receiver performing the second processing corresponding to the first processing on the first data, thereby reducing the processing complexity and delay of the receiver.

[0218] Mode three: the second data includes virtual modulation symbols.

[0219] It should be noted that the virtual modulation symbol can be a signal after modulation processing, that is, the virtual modulation symbol is a signal that has undergone other processing processes after the modulation processing in one or more of the above-mentioned transmission processes (for example, a signal to be RE mapped). In other words, the virtual modulation symbol can refer to a symbol that has not undergone (or does not need to undergo) modulation processing, wherein the virtual modulation symbol can be called a pseudo-modulation symbol.

[0220] In mode three, the first data is the data obtained after the second data undergoes the first processing, and the second data includes a virtual modulation symbol, wherein the virtual modulation symbol does not need to undergo modulation processing and related processing (such as possible processing before the modulation processing, including encoding processing), that is, the first processing may not include modulation processing and related processing. Thus, through the pre-configured virtual modulation symbols, the first communication device can omit or not perform modulation processing and related processing, thereby reducing the processing complexity and delay of the sender. In addition, through the pre-configured virtual modulation symbols, after receiving the first data, the receiver of the first data (such as the second communication device) can also omit or not perform the demodulation processing corresponding to the modulation processing in the process of the receiver performing the second processing corresponding to the first processing on the first data, thereby reducing the processing complexity and delay of the receiver.

[0221] Optionally, the number of virtual modulation symbols is associated with at least one of the number of configured REs and the number of configured streams.

[0222] Optionally, the virtual modulation symbol is a symbol determined by a preset symbol sequence or a random sequence, for example, a preset or pseudo-random QAM symbol, or a random signal satisfying a specific distribution (such as a complex Gaussian signal).

[0223] Exemplarily, take the case where the first neural network includes a neural network deployed in a transmitter (e.g., a first communication device). The processing involved in the signal transmission process of the first communication device includes the process shown in Figure 4b, such as channel coding / interleaving, modulation, mapping, waveform, and T-NN processing. In mode three, when the second data includes virtual modulation symbols, the virtual modulation symbols are defined as signals to be mapped to transmission resources, that is, modulated symbols in traditional data transmission. As shown in Figure 4b, the second data containing virtual modulation symbols can be used as input to the mapping module (i.e., there is no need to perform channel coding / interleaving, modulation, etc. to reduce complexity and delay). Thereafter, the first communication device can obtain the first data after precoding, waveform, etc. on the second data containing virtual modulation symbols, and send the first data in step S201.

[0224] Optionally, in method three, the second data may include other information in addition to virtual modulation symbols. The difference from the processing of virtual modulation symbols is that the other information may also undergo channel coding / interleaving processing and / or modulation processing before entering the mapping module.

[0225] Mode 4: The second data includes a virtual sending signal.

[0226] It should be noted that the virtual transmission signal can be a signal sent after waveform shaping processing or time domain neural network processing, that is, the virtual transmission signal is a signal that undergoes other processing processes after waveform shaping processing in one or more of the above-mentioned transmission processes (for example, a signal to be carrier modulated). In other words, the virtual transmission signal can refer to a signal that has not undergone (or does not need to undergo) waveform shaping processing, wherein the virtual transmission signal can be called a pseudo transmission signal.

[0227] In mode 4, the first data is the data obtained after the second data undergoes the first processing, and the second data includes a virtual transmission signal, wherein the virtual transmission signal does not need to undergo waveform shaping processing and related processing (for example, processing that may exist before the waveform shaping processing, including encoding processing, modulation processing, etc.), that is, the first processing may not include waveform shaping processing and related processing. Thus, through the pre-configured virtual transmission signal, the first communication device can omit or not perform waveform shaping processing and related processing, thereby reducing the processing complexity and delay of the sender. In addition, through the pre-configured virtual transmission signal, the receiver of the first data (for example, the second communication device) can also omit or not perform the waveform receiving processing corresponding to the waveform shaping processing during the process of the receiver performing the second processing corresponding to the first processing on the first data after receiving the first data, thereby reducing the processing complexity and delay of the receiver.

[0228] Optionally, the transmitted signal is a random signal sequence, a preconfigured signal sequence, a constant power signal or a random signal.

[0229] Exemplarily, take the example of a first neural network including a neural network deployed in a transmitter (e.g., a first communication device). The processing involved in the signal transmission process of the first communication device includes the process shown in Figure 4c, such as channel coding / interleaving, modulation, mapping, waveform, and T-NN processing of AE-NN. In method four, when the second data includes a virtual transmission signal, the virtual transmission signal can be defined as a sampled signal to be transmitted. As shown in Figure 4c, the second data containing the virtual transmission signal can be used as the input of T-NN (i.e., there is no need to perform channel coding / interleaving, modulation, mapping, waveform and other processing to reduce complexity and delay). Thereafter, the first communication device can obtain the first data after digital-to-analog conversion of the second data containing the virtual transmission signal, and send the first data in step S201.

[0230] Optionally, in method four, the second data may include other information in addition to the virtual transmit signal. The difference from the processing of the virtual transmit signal is that the other information may also undergo one or more of channel coding / interleaving processing, modulation processing, mapping processing and waveform processing before entering the mapping module.

[0231] In one possible implementation, the method further includes: the first communication device sending third data, where the third data is data obtained after the second data has been subjected to the first processing; wherein the signal power of the first data is different from the signal power of the third data, and / or the modulation order of the first data is different from the modulation order of the third data. Specifically, the first communication device may also send third data obtained after the second data has been subjected to the first processing, wherein the signal power of the first data is different from the signal power of the third data, and / or the modulation order of the first data is different from the modulation order of the third data, so that a receiver of the first data can obtain the first data and the third data, and subsequently optimize the data processing process of wireless communication based on the first data and the third data having different signal powers (and / or different modulation orders).

[0232] Taking Figure 5a as an example, when transmitting the preconfigured second data, parallel transmission resources with different powers (e.g., at least two of power 1, power 2, power 3, and power 4 in 5a) can be preconfigured. First data and third data with different powers can be obtained and transmitted simultaneously. For example, the first data and third data with different powers can be represented as "p0" and "p1" in Figure 5b. The preconfigured second data can be processed by the same modulation module and then passed through different power control modules to generate data with different powers, which are then mapped to the preconfigured resources and transmitted.

[0233] Taking Figure 6a as an example, when the pre-configured second data is transmitted, different configurations (such as Mod-4 and Mod-6 in 6a) can be transmitted simultaneously in one transmission, where Mod-4 can refer to a modulation order of 4, such as 16-quadrature amplitude modulation (QAM); Mod-6 can refer to a modulation order of 6, such as 64QAM. The first data and the third data are constructed under similar channel conditions. For example, the first data and the third data of different modulation orders can be represented as "q0" and "q1" in Figure 6b. Different data can be generated and processed by different AE-NN and other modules respectively, and then mapped to pre-configured resources for transmission, such as different orders are mapped to pre-configured time-frequency resources.

[0234] Optionally, the time-frequency resources carrying the first data and the time-frequency resources carrying the third data are located in the configured first time-frequency resources. For example, taking the first communication device as a terminal device and the second communication device as a network device as an example, the second communication device can configure the first time-frequency resource to the first communication device by sending configuration information; accordingly, after receiving the configuration information, the first communication device determines the first sub-resource as the time-frequency resource carrying the first data in the first time-frequency resource configured by the configuration information, and determines the second sub-resource as the time-frequency resource carrying the third data, and the first sub-resource and the second sub-resource are both subsets of the first time-frequency resource and the first sub-resource and the second sub-resource are different. In addition, the resource indexes of the first sub-resource and the second sub-resource can be configured through the configuration information or by pre-configuration, which is not limited here.

[0235] Optionally, the first data and third data sent based on different configurations can be used to evaluate and compare models of corresponding configurations. Taking the first data and third data of different modulation orders as an example, the neural network deployed in the first communication device or the second communication device can include a neural network corresponding to Mod-4 and a neural network corresponding to Mod-6. The processing of the first data and the third data can be used to evaluate and compare the neural network corresponding to Mod-4 and the neural network corresponding to Mod-6, respectively. The evaluation results or comparison results can be used for the subsequent selection of neural networks under different channel conditions.

[0236] Based on the technical solution shown in Figure 2, the first data sent by the first communication device in step S201 is data obtained after the second data has been subjected to the first processing, where the second data is preconfigured. In other words, the second communication device can determine the second data based on the preconfiguration, so that in step S202, the second communication device can perform the second processing corresponding to the first processing on the received first data to obtain an estimate of the second data. Based on the estimated second data and the preconfigured second data, the second communication device can optimize the data processing process of the wireless communication to improve communication efficiency.

[0237] Please refer to FIG7 , which is a schematic diagram of an implementation of the communication method provided in this application. The method includes the following steps.

[0238] It should be noted that, in FIG7 , the method is illustrated by taking the first communication device and the second communication device as the execution subjects of the interaction diagram as an example, but the present application does not limit the execution subjects of the interaction diagram. For example, the execution subject of S701 in FIG7 and the corresponding implementation method is the first communication device, and the execution subject may also be a chip, chip system, or processor that supports the first communication device to implement the method, or a logic module or software that can implement all or part of the functions of the first communication device. The second communication device in S701-S702 in FIG7 and the corresponding implementation method may also be replaced by a chip, chip system, or processor that supports the second communication device to implement the method, or may be replaced by a logic module or software that can implement all or part of the functions of the second communication device.

The first data and third data are both data obtained after a first processing is performed on the second data, the signal power of the first data is different from the signal power of the third data, and / or the modulation order of the first data is different from the modulation order of the third data. The first communication device transmits the first data and the third data.

[0240] S702. The second communication device performs a second process corresponding to the first process on the first data and the third data.

[0241] It should be noted that the technical solution shown in FIG7 can also refer to the description of FIG2 and related technical solutions.

[0242] Based on the technical solution shown in FIG7 , the first communication device may transmit, in step S701, first data and third data obtained after the second data has been subjected to the first processing, wherein the signal power of the first data is different from the signal power of the third data, and / or the modulation order of the first data is different from the modulation order of the third data. The second data is preconfigured, enabling a receiver of the first data to obtain the first data and the third data, and subsequently optimizing the data processing process of wireless communication based on the first data and the third data having different signal powers (and / or different modulation orders).
