Description

Technical Field

[0001] This application relates to the field of communication technology, and more specifically, to a communication method and a communication device. Background Technology

[0002] Both wireless communication and wireless sensing are based on electromagnetic wave theory. The transmitting end modulates electromagnetic wave signals, enabling them to carry source information. During propagation, these signals are affected by the wireless environment; that is, they are modulated by the environment and thus also carry environmental information. The receiving end analyzes the electromagnetic wave signals to obtain not only the carried source information but also sensing information reflecting the characteristics of the propagation environment. This makes integrated sensing and communication (ISAC) possible.

[0003] To match different wireless channel conditions, the New Radio Interface (NR) supports various modulation and coding schemes (MCS) for signal modulation and coding. Different MCSs correspond to different combinations of modulation order and coding rate, and different modulation orders correspond to different modulation methods, such as quadrature phase shift keying (QPSK) and quadrature amplitude modulation (QAM). In communication scenarios, using a higher modulation order can increase the information transmission rate. However, in ISAC scenarios, while increasing the information transmission rate, sensing performance also needs to be considered. For sensing, it is desirable to reduce the modulation order to improve the signal transmission's anti-interference capability. Therefore, in ISAC scenarios, determining a suitable MCS to achieve better communication and sensing performance is a problem that needs to be solved. Summary of the Invention

[0004] This application provides a communication method and a communication device that can select a suitable MCS to improve the performance of communication and sensing.

[0005] Firstly, a communication method is provided, which can be applied to a transmitting device. Unless otherwise specified, the term "transmitting device" in this application can refer to the transmitting device itself (e.g., a network device, a terminal device), a component in the transmitting device (e.g., a processor, a chip, or a chip system), or a logic module or software that can implement all or part of the functions of the transmitting device.

[0006] The method includes: sending first indication information, the first indication information indicating an index corresponding to a first MCS, the first MCS being used for modulation and coding processing of integrated communication sensing signals, the first MCS corresponding to one or more modulation schemes; and transmitting data signals according to the first MCS.

[0007] Based on the above scheme, the transmitting and receiving devices can transmit data signals according to the modulation and coding scheme (MCS) used for sensing signals, which can improve the performance of communication and sensing. Furthermore, the MCS used for sensing signals can correspond to one or more modulation schemes, increasing the flexibility of modulation scheme selection.

[0008] In some implementations of the first aspect, the first MCS belongs to a first MCS table, which belongs to a first type of MCS table. The first type of MCS table also includes multiple second MCSs, which are used for modulation and coding processing of communication signals.

[0009] Based on the above scheme, by including the first MCS and the second MCS in the first type of MCS table, the selection of MCS for different signals (e.g., communication signals or sensing signals) can be more flexible.

[0010] In some implementations of the first aspect, the first type of MCS table includes multiple MCS tables, in which the same modulation order corresponds to different code rates. The method further includes: sending second indication information, the second indication information indicating the first MCS table, the first MCS table being one of the multiple MCS tables.

[0011] Based on the above scheme, the transmitting device can select a suitable MCS table from the first type of MCS table according to different bit rates.

[0012] In some implementations of the first aspect, the first indication information occupies more than 5 bits.

[0013] In some implementations of the first aspect, the first MCS belongs to a first MCS table, the first MCS table belongs to a second type of MCS table, the second type of MCS table consists of N MCSs, the N MCSs are used for modulation and coding processing of integrated communication and sensing signals, each of the N MCSs corresponds to one or more modulation schemes, and N is a positive integer.

[0014] Based on the above scheme, the first MCS table can be selected from the second type of MCS table. The second type of MCS table is an MCS table used for inductive signals. That is, the MCS included in the second type of MCS table is used for modulation and coding processing of inductive signals. This scheme is compatible with the indication method of MCS in the existing standard.

[0018] In some implementations of the first aspect, downlink control information is sent, which carries a first field indicating that the first MCS table belongs to the second type of MCS table.

[0023] Based on the above scheme, the signaling overhead can be saved by indicating that the first MCS table belongs to the second type of MCS table through resource configuration.

[0024] In some implementations of the first aspect, the modulation order corresponding to the first MCS is Q, and the value of Q can be 3 or 5.

[0025] Based on the above scheme, the modulation order corresponding to the first MCS can be set to 3 or 5, which can improve the performance of communication and sensing.

[0027] Based on the above scheme, the flexibility of the transmitting device in selecting a modulation method with a modulation order of 3 can be increased, and the communication and sensing performance can be improved by configuring the modulation method corresponding to the first MCS to include at least one of 8-PSK and 8-P-QAM.

[0101] Figure 10 and Figure 11 This is a schematic diagram of the chip system provided in this application. Detailed Implementation

[0102] The technical solutions in this application will now be described with reference to the accompanying drawings.

[0103] Figure 1 This is a schematic diagram of the architecture of the communication system used in the embodiments of this application. Figure 1 As shown, the communication system includes a radio access network (RAN) 100. Optionally, the communication system may also include a core network 200 and an Internet 300.

[0104] RAN 100 may include at least one RAN node (such as...) Figure 1 110a and 110b, collectively referred to as 110, may also include at least one terminal (such as...). Figure 1 RAN 100, denoted as RAN 120a-120j, is collectively referred to as RAN 120. RAN 100 may also include other RAN nodes, such as wireless relay equipment and / or wireless backhaul equipment. Figure 1 (Not shown in the image). Terminal 120 is wirelessly connected to RAN node 110. Terminals and RAN nodes can be interconnected via wired or wireless means. RAN node 110 is wirelessly or wired connected to core network 200. The core network equipment in core network 200 and RAN node 110 in RAN 100 can be independent physical devices, or they can be the same physical device integrating some or all of the logical functions of the core network equipment and some or all of the logical functions of the RAN node.

[0105] RAN 100 can be an evolved universal terrestrial radio access (E-UTRA) system, an NR system, a 6th generation (6G) radio access system, or a future radio access system as defined in the 3rd generation partnership project (3GPP), or a wireless fidelity (WiFi) system. RAN 100 can also include two or more of the above-mentioned different radio access systems. RAN 100 can also be an open RAN (O-RAN).

[0106] RAN nodes, also known as radio access network devices, RAN entities, or access nodes, are used to help terminals access communication systems wirelessly. In one application scenario, an RAN node can be a base station, an evolved NodeB (eNodeB), a transmission reception point (TRP), a next-generation NodeB (gNB) in a 5G mobile communication system, a next-generation base station in a 6G mobile communication system, a base station in a future mobile communication system, or an access node in a WiFi system. RAN nodes can also be macro base stations (such as...) Figure 1 110a in the text), can also be a micro base station or an indoor station (such as... Figure 1 110b in the middle can also be a relay node or a donor node.

[0107] In another application scenario, multiple RAN nodes can collaborate to help terminals achieve wireless access, with different RAN nodes implementing different functions of the base station. For example, a RAN node can be a central unit (CU), a distributed unit (DU), or a radio unit (RU). The CU performs the functions of the base station's Radio Resource Control (RRC) and Packet Data Convergence Protocol (PDCP), and can also perform the functions of the Service Data Adaptation Protocol (SDAP). The DU performs the functions of the base station's Radio Link Control (RANC) and Medium Access Control (MAC) layers, and can also perform some or all of the physical layer functions. For specific descriptions of these protocol layers, refer to the relevant 3GPP technical specifications. The RU can be used to implement radio frequency signal transmission and reception. The CU and DU can be two independent RAN nodes, or they can be integrated into the same RAN node, such as within a baseband unit (BBU). RUs can be included in radio frequency equipment, such as remote radio units (RRUs) or active antenna units (AAUs). CUs can be further divided into two types of RAN nodes: CU-control plane and CU-user plane.

[0108] In different systems, RAN nodes can have different names. For example, in an O-RAN system, a CU can also be called an open CU (O-CU), a DU can also be called an open DU (O-DU), and an RU can be called an open RU (O-RU). In this application, the RAN node can be implemented through software modules, hardware modules, or a combination of software and hardware modules. For example, the RAN node can be a server loaded with the corresponding software modules. The embodiments of this application do not limit the specific technology or device form used in the RAN node. For ease of description, a network device or base station is used as an example of a RAN node below.

[0109] A terminal can be a device with wireless transceiver capabilities, capable of sending signals to or receiving signals from a base station. Terminals can also be referred to as terminal equipment, user equipment (UE), mobile station, mobile terminal, etc. Terminals can be widely used in various scenarios, such as device-to-device (D2D), vehicle-to-everything (V2X) communication, machine-type communication (MTC), Internet of Things (IoT), virtual reality, augmented reality, industrial control, autonomous driving, telemedicine, smart grids, smart furniture, smart offices, smart wearables, smart transportation, smart cities, etc. Terminals can be mobile phones, tablets, computers with wireless transceiver capabilities, wearable devices, vehicles, airplanes, ships, robots, robotic arms, smart home devices, etc. The embodiments of this application do not limit the specific technology or device form used in the terminal.

[0110] Base stations and terminals can be fixed or mobile. They can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; they can also be deployed on water; and they can be deployed on aircraft, balloons, and satellites. The embodiments of this application do not limit the application scenarios of the base stations and terminals.

[0111] The roles of base stations and terminals can be relative, for example, Figure 1 The helicopter or drone 120i can be configured as a mobile base station. For terminals 120j accessing the wireless access network 100 via 120i, terminal 120i is a base station; however, for base station 110a, 120i is a terminal, meaning that 110a and 120i communicate via a wireless air interface protocol. Of course, 110a and 120i can also communicate via a base station-to-base station interface protocol; in this case, 120i is also a base station relative to 110a. Therefore, both base stations and terminals can be collectively referred to as communication devices. Figure 1 The 110a and 110b in the text can be referred to as communication devices with base station functions. Figure 1 The 120a-120j in the text can be referred to as communication devices with terminal functions.

[0112] Communication between base stations and terminals, between base stations, and between terminals can be conducted using licensed spectrum, unlicensed spectrum, or both simultaneously. Communication can be conducted using spectrum below 6 GHz, spectrum above 6 GHz, or both simultaneously. The embodiments of this application do not limit the spectrum resources used for wireless communication.

[0113] In the embodiments of this application, the functions of the base station can be executed by modules (such as chips) within the base station, or by a control subsystem that includes base station functions. This control subsystem, including base station functions, can be a control center in the aforementioned application scenarios such as smart grids, industrial control, intelligent transportation, and smart cities. Similarly, the functions of the terminal can be executed by modules (such as chips or modems) within the terminal, or by a device that includes terminal functions.

[0114] In this application, the base station sends downlink signals or downlink information to the terminal, with the downlink information carried on the downlink channel; the terminal sends uplink signals or uplink information to the base station, with the uplink information carried on the uplink channel. In order to communicate with the base station, the terminal needs to establish a radio connection with a cell controlled by the base station. The cell with which the terminal has established a radio connection is called the terminal's serving cell.

[0115] As an example, a RAN node can be a satellite base station, as described below. Figure 2 illustrate.

[0116] Figure 2 This is a schematic diagram illustrating one application scenario to which this application applies. For example... Figure 2 As shown in (a) and (b), satellite base stations provide communication services to terminals. For example, a satellite base station transmits downlink data to a terminal, where the data is encoded using channel coding, and the channel-coded data is then transmitted to the terminal after constellation modulation. Similarly, a terminal transmits uplink data to a satellite base station; the uplink data can also be encoded using channel coding, and the encoded data is then transmitted to the satellite base station after constellation modulation. Additionally, as... Figure 2 As shown in (b), satellite base stations can also communicate with ground base stations, meaning that satellites can act as both base stations and terminals.

[0117] In this application, "satellite" can refer to unmanned aerial vehicles (UAVs), hot air balloons, low-Earth orbit (LEO) satellites, medium-Earth orbit (MEO) satellites, high-Earth orbit (HEO) satellites, etc. "Satellite" can also refer to non-terrestrial base stations or non-terrestrial equipment, etc.

[0118] It should be understood that this application can be applied to scenarios involving communication between network devices. Figure 2The scenario shown in (b) can also be seen as an example of network devices communicating with each other, where both the satellite and the base station can be considered as a network device.

[0119] As one implementation method, this application can be applied to satellite inter-satellite link communication systems.

[0120] like Figure 2 As shown in (c), the inter-satellite link communication system can be divided into two main parts: an acquisition-pointing-tracking (APT) subsystem and a communication subsystem. The communication subsystem is primarily responsible for the transmission of inter-satellite information and forms the core of the inter-satellite communication system. The APT system is mainly responsible for acquisition, alignment, and tracking between satellites. Acquisition involves determining the direction of the incoming incident signal, while alignment involves adjusting the transmitted wave to aim at the receiving direction. Tracking involves continuously adjusting alignment and acquisition via APT throughout the communication process. To minimize attenuation and interference in the channel while maintaining high security and transmission rate, the APT must be adjusted in real time to continuously adapt to changes.

[0121] It should be understood that current APT systems are all optical systems, which have the disadvantage of being difficult to align and requiring mechanical adjustment of the pointing. Most existing communication subsystems are optical communication systems, with some microwave band systems, and most use a single high-gain antenna. Existing APT systems and communication subsystems are independent systems. The disadvantages are that optical communication is susceptible to vibration and other factors, resulting in unstable data rates; millimeter-wave frequencies are low, communication capacity is low, and the antenna requires mechanical adjustment of its pointing.

[0122] As another example, a RAN node can be a station (STA), as described below. Figure 3 illustrate.

[0123] Figure 3 This is a schematic diagram illustrating another application scenario to which this application applies. For example... Figure 3As shown, the resource configuration method provided in this application is applicable to data communication between sites. A site can be an access point (AP) or a non-access point station (non-AP STA), referred to as an AP and a non-AP site, respectively. Specifically, the solution in this application is applicable to data communication between an AP and one or more non-AP sites (e.g., data communication between AP1 and non-AP STA1, non-AP STA2), data communication between APs (e.g., data communication between AP1 and AP2), and data communication between non-AP STAs (e.g., data communication between non-AP STA2 and non-AP STA3).

[0124] An access point is a point of access for a terminal (e.g., a mobile phone) to enter a wired (or wireless) network. It is mainly deployed in homes, buildings, and campuses, with a typical coverage radius of tens to hundreds of meters. Of course, it can also be deployed outdoors. An access point acts as a bridge connecting wired and wireless networks, its main function being to connect various wireless network clients together and then connect the wireless network to the Ethernet.

[0125] Specifically, an access point can be a terminal or network device with a Wi-Fi chip. This network device can be a server, router, switch, bridge, computer, mobile phone, relay station, vehicle-mounted equipment, wearable device, network equipment in 5G networks and future 6G networks, or network equipment in a public land mobile network (PLMN). The access point can be a device that supports Wi-Fi standards. For example, the access point can also support one or more standards of the IEEE 802.11 family, such as 802.11a, 802.11b, 802.11g, 802.11n, 802.11ac, 802.11ax, 802.11be, 802.11ad, and 802.11ay.

[0126] Non-AP sites can be wireless communication chips, wireless sensors, or wireless communication terminals, and are also referred to as users, user equipment (UE), access terminals, user units, user stations, mobile stations, mobile stations, remote stations, remote terminals, mobile devices, user terminals, terminals, wireless communication equipment, user agents, or user devices. Non-AP sites can be cellular phones, cordless phones, session initiation protocol (SIP) phones, wireless local loop (WLL) stations, personal digital assistants (PDAs), handheld devices with wireless communication capabilities, computing devices or other processing devices connected to a wireless modem, in-vehicle devices, IoT devices, wearable devices, terminal devices in 5G networks, terminal devices in future 6G networks, or terminal devices in PLMNs, etc. Non-AP sites can be devices that support WLAN standards. For example, non-AP sites can support one or more standards of the IEEE 802.11 family, such as 802.11a, 802.11b, 802.11g, 802.11n, 802.11ac, 802.11ax, 802.11be, 802.11ad, and 802.11ay.

[0127] For example, non-AP sites can be mobile phones, tablets, set-top boxes, smart TVs, smart wearable devices, vehicle communication devices, computers, Internet of Things (IoT) nodes, sensors, smart home devices such as smart cameras, smart remote controls, smart water and electricity meters, and sensors in smart cities.

[0128] The aforementioned AP or non-AP sites may include transmitters, receivers, memory, processors, etc., wherein the transmitter and receiver are used for transmitting and receiving packet structures, respectively, the memory is used for storing signaling information and pre-agreed preset values, etc., and the processor is used for parsing signaling information and processing related data, etc.

[0129] The communication systems described above that are applicable to this application are merely illustrative examples, and the communication systems applicable to this application are not limited thereto.

[0130] To facilitate understanding of the embodiments of this application, some basic concepts involved in this application will be briefly explained.

[0131] 1. Perception

[0132] The technical principles of sensing differ somewhat from those of communication. In communication, the transmitting end modulates information onto radio waves and sends it to the receiving end, which then demodulates the signal to obtain the information. Sensing, however, requires the transmitting end to send radio waves in a specific direction. When these radio waves strike a target surface, they are reflected, and the receiving end receives and processes these reflected waves to obtain information such as the target's position, speed, and type.

[0133] Sensing signals are signals used to sense or detect targets; in other words, they are signals used to sense or detect environmental information. For example, sensing signals are electromagnetic waves transmitted by network devices to sense environmental information. Sensing signals can also be called radar signals, radar sensing signals, detection signals, radar detection signals, environmental sensing signals, etc.

[0134] Sensing can generally be divided into two modes: single-site sensing and dual-site sensing. In single-site sensing, the transmitting and receiving ends of the sensing signal are the same device. In the signal processing flow, the sensing station both transmits and receives the signal reflected from the target surface; therefore, single-site sensing is also called the self-transmitting and self-receiving mode. In dual-site sensing, the transmitting and receiving ends of the sensing signal are different devices. In the signal processing flow, after sensing station A transmits the sensing signal, the signal reflected from the target surface is received by sensing station B; therefore, dual-site sensing is also called the A-transmitting and B-receiving mode.

[0135] 2. Integrated Sensing and Communication (ISAC)

[0136] Communication and sensing integration, also known as communication-sensing fusion, refers to the introduction of "sensing" capabilities on the basis of base station support for mobile communication transmission. The characteristic of sensing capabilities is "transmission and reception" (i.e., transmitting excitation signals and using echo signals to detect and sense targets, with the same working mechanism as radar).

[0137] Figure 4 This is a schematic diagram of an integrated communication and sensing site. Figure 4 As shown, the integrated communication and sensing station A not only transmits sensing signals (e.g., sensing excitation signals) but also receives signals reflected from the target surface (e.g., sensing echo signals). Furthermore, the integrated communication and sensing station A can also transmit downlink communication signals to the target and receive uplink communication signals transmitted by the target.

[0138] It should be understood that the site performing communication sensing can be either a network device or a terminal device.

[0139] The perceived targets can include various tangible objects on the ground that can be perceived, such as mountains, forests, or buildings, as well as vehicles, drones, and terminal devices. It should be noted that... Figure 4 The vehicles, drones, and user equipment (UEs) shown are merely examples. The sensed targets may include not only vehicles and drones, but also other movable objects such as pedestrians and terminal equipment (including UEs). This application does not impose any limitations on this. It should be understood that the integrated communication and sensing station A can communicate not only with the UE shown in the figure, but also with sensed targets (such as drones and vehicles). This application does not impose any limitations on this.

[0140] It should also be understood that the sensed target is a target that can be sensed by a network device with sensing capabilities, and that the target can feed back electromagnetic waves to the network device. The sensed target can also be called a detected target, a sensed object, a sensed device, etc., and the embodiments of this application do not limit it.

[0141] Figure 4 The diagram illustrates a communication and sensing integrated site in single-site sensing mode. For information on communication and sensing integrated sites in dual-site sensing mode, please refer to [reference needed]. Figure 4 As shown, no further details will be provided.

[0142] The above Figure 4 The scenario described is just one example. In one possible scenario, the network side may include multiple integrated communication and sensing sites, such as three or more integrated communication and sensing sites.

[0143] 3. Modulation and coding scheme (MCS)

[0144] In signal processing, data signals can be encoded and modulated. In MCS (Multi-Signal System), encoding refers to channel coding, and modulation refers to mapping the encoded data to the smallest unit of time-domain resources—the symbol. During encoding, multiple redundant bits can be added for error correction, thus introducing the concept of code rate. Code rate represents the proportion of valid data in the total encoded data. For example, if the code rate (represented by the symbol R) is 3 / 4, it means that 3 / 4 of the encoded data is valid data, and the remaining 1 / 4 is redundant bits.

[0145] Different code rates and modulation schemes constitute different MCSs. Existing protocols may include at least one of the following modulation schemes: binary phase shift keying (BPSK), quadrature phase shift keying (QPSK), quadrature amplitude modulation (QAM), 64-QAM, 256-QAM, 1024-QAM, or 4096-QAM. In QAM, the value preceding 2 is a power of n, where n is a positive integer and can represent the number of bits mapped to a single symbol.

[0146] 4. Modulation and Coding Strategy Table (MCS table)

[0147] The MCS table can be used to indicate the correspondence between different modulation schemes (such as QPSK, 16-QAM, 64-QAM, 256-QAM, etc.) and code rates.

[0148] The MCS table allows the network and terminal sides to flexibly select appropriate modulation and coding schemes as needed. In the downlink (e.g., PDSCH) and uplink (e.g., physical uplink shared channel, PUSCH), the UE and RAN select the appropriate MCS index from the MCS table based on channel conditions, service requirements, and other factors, thereby determining the specific modulation scheme and code rate.

[0149] Taking new radio (NR) as an example, three MCS tables are predefined for PDSCH: Table 1, Table 2, and Table 3. Table 1 is the high-spectral-efficiency MCS table with a maximum modulation order of 6; Table 2 is the MCS table with a maximum modulation order of 8; and Table 3 is the low-spectral-efficiency MCS table with a maximum modulation order of 6. Each table contains multiple MCS indices, each corresponding to a specific modulation scheme and coding rate (target code rate × 1024).

[0150] Table 1

[0151]

[0152]

[0153] Table 2

[0154]

[0155]

[0156] Table 3

[0157]

[0158] Taking Table 1 as an example, the first column in Table 1 is the MCS index I. MCS The indexes 29-31 are reserved; the second column is the modulation order Q. m This indicates the modulation scheme used; that is, a value of one modulation order corresponds to one modulation scheme. For example, Q... m When Q = 2, the corresponding modulation scheme is QPSK; Q m When Q = 4, the corresponding modulation scheme is 16-QAM; m When the value is 6, the corresponding modulation scheme is 64-QAM. The third column is the code rate (or coding rate), which represents the expected code rate after selecting the modulation scheme and corresponding redundancy corresponding to the MCS index; the fourth column is the spectral efficiency, which represents the frequency efficiency corresponding to the MCS index. Spectral efficiency is positively correlated with code rate, that is, the higher the code rate, the higher the spectral efficiency.

[0159] The transmitting device can instruct the receiving device which predefined MCS table to use through higher-level parameters (e.g., MCS-table), and then indicate the index of the MCS used in that MCS table through the MCS indication field in the downlink control information (DCI).

[0160] 4. Pruned quadrature amplitude modulation (QAM) (P-QAM):

[0161] Existing 5G symbol modulation supports modulation schemes such as quadrature phase shift keying (QPSK), 16-QAM, and 64-QAM. These modulation schemes can match different channel conditions and achieve better transmission rates under corresponding channel conditions. However, for sensing applications, using modulation schemes like 16-QAM and 64-QAM is not optimal under certain channel conditions. Therefore, P-QAM modulation schemes, also known as pruned QAM, are proposed. In other words, a new P-QAM constellation is constructed by selecting constellation points on the existing QAM constellation diagram.

[0162] For example, Figure 5 The diagram shown illustrates one method for determining a 32-P-QAM constellation. (As shown...) Figure 5As shown, a 64-QAM constellation diagram is constructed from 64 constellation points. Selecting the constellation points within the dashed box from these 64 points can construct a 32-P-QAM constellation diagram. Here, 32-P-QAM is a 5-bit modulation scheme, meaning that 5 bits are mapped to a single symbol. I and Q represent the in-phase component and quadrature component, respectively.

[0163] It should be understood that in x-QAM or xP-QAM, 'x' represents the number of symbols used for information transmission in that modulation scheme, also known as the modulation order. The modulation order can be determined by the number of bits mapped to a single symbol in that modulation scheme. For example, if the number of bits mapped to a single symbol is 6, then the corresponding modulation order is 2. 6 =64.

[0164] It should also be understood that the constellation diagram corresponding to a modulation scheme can represent the distribution of symbols used to transmit information in the complex plane under that modulation scheme. Specifically, each constellation point on the constellation diagram represents a symbol with a specific amplitude and phase. For example, in 64-QAM, since there are 64 different symbols, there are 64 points on the constellation diagram. These points are represented by components on the I-axis (real part) and Q-axis (imaginary part), representing the amplitude adjustment on two orthogonal carriers, respectively. The distance of the constellation point from the origin represents the modulated amplitude, while the angle between the constellation point and the positive direction of the real axis represents the modulated phase.

[0165] In communication scenarios, the information transmission rate can be increased by using a high modulation order MCS that matches the channel conditions. Under the same channel conditions, for sensing, it is desirable to reduce the modulation order to improve the anti-interference capability of the signal transmission process. Therefore, in the ISAC scenario, how to determine a suitable MCS to meet the performance requirements of communication and sensing (referred to as synesthesia) is a problem that needs to be solved.

[0166] In view of this, this application provides a communication method and a communication device that can improve the sensing performance by selecting a suitable MCS.

[0167] To facilitate understanding of the embodiments of this application, the following points are explained before introducing the embodiments of this application.

[0168] First, the various numerical designations used in the embodiments of this application are merely for descriptive convenience and are not intended to limit the scope of the embodiments of this application. The order of the process numbers does not imply the order of execution; the execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of this application.

[0169] Second, in the embodiments of this application, the terms "first," "second," and various numerical designations are used for ease of description and are not intended to limit the scope of the embodiments of this application. For example, they are used to distinguish different indication information.

[0170] Third, in the embodiments of this application, descriptions such as "when," "under what circumstances," and "if" all refer to the device making corresponding processing under certain objective circumstances, and are not limited to a specific time. They do not require the device to make a judgment action during implementation, nor do they imply any other limitations.

[0171] Figure 6 This is a schematic diagram of an encoding method 600 provided in this application.

[0172] It is understood that method 600 can be executed by both the sending device and the receiving device. Unless otherwise specified, "sending device" or "receiving device" can refer to the sending device or receiving device itself, or it can refer to a device that enables the sending device or receiving device to implement this function. For ease of description, the following text will use "sending device" and "receiving device" to describe it. Among them, the sending device can be a terminal device or a network device, and the receiving device can be a terminal device or a network device.

[0173] like Figure 6 As shown, the method includes the following steps.

[0174] S610, the transmitting device sends first indication information to the receiving device. Accordingly, the receiving device receives the first indication information.

[0175] The first indication information is used to indicate the index corresponding to the first MCS. The first MCS can be used for modulation and coding processing of integrated communication and sensing signals, and the first MCS corresponds to one or more modulation schemes.

[0176] For simplicity, the integrated communication and sensing signal will be referred to as "sensing signal" in the following text. A sensing signal can refer to a signal used for communication that has a sensing function, a signal used for sensing that has a communication function, or a signal that only has a sensing function. The specific function of the signal used can be determined according to the actual situation and is not limited.

[0177] For example, the index corresponding to the first MCS belongs to the first MCS table. The first MCS table may include a correspondence between at least one index and at least one MCS. That is, the first indication information indicates an index in the first MCS table that has a correspondence with the first MCS.

[0178] For example, the transmitting device can select the first MCS table from at least one MCS table. There are two ways to select the first MCS table.

[0179] One possible implementation is to select the first MCS from a first type of MCS table. The first type of MCS table includes N first MCSs used for modulation and coding of the sensing signal; the first type of MCS table also includes M second MCSs used for modulation and coding of the communication signal, where M and N are positive integers.

[0180] Another possible implementation is to select the first MCS table from the second type of MCS table. The second type of MCS table can include K first MCSs used for modulation and coding processing of the sensing signal, where K is a positive integer.

[0181] The following details the two possible implementation methods described above.

[0182] Specifically, for the first possible implementation, the M second MCSs in the first type of MCS table can be understood as one or more MCSs in the existing MCS table.

[0183] For example, the second MCS is any row in Tables 1 to 3.

[0184] For example, the second MCS is any row in Tables 1 to 3, and the index of that row changes. That is, adding N new first MCSs may change the index of the MCSs in the existing tables, but the modulation scheme, code rate, and spectral efficiency corresponding to the MCSs do not change.

[0185] In other words, the first type of MCS table can be understood as adding N first MCSs to the existing MCS table to form a new MCS table, where the added N first MCSs are used for modulation and coding processing of the sensing signal.

[0186] For example, for the first type of MCS table, the modulation order of one of the newly added N first MCSs (denoted as MCS#1) may or may not be included in the modulation order of the M second MCSs. For example, the modulation order of the M second MCSs includes 2, 4, 6, and 8 (the modulation order of the MCSs in Tables 1 to 3), and the modulation order of MCS#1 can be 2, 4, 6, or 8; optionally, the modulation order of MCS#1 can also be 3 or 5.

[0187] Furthermore, MCS#1 can correspond to one or more modulation schemes. When the modulation order corresponding to MCS#1 is included in the modulation orders corresponding to the M second MCSs, compared to the M second MCSs having the same modulation order as MCS#1 (denoted as MCS#2) corresponding to one modulation scheme, MCS#1 can correspond to one or more modulation schemes; when the modulation order corresponding to MCS#1 is not included in the modulation orders corresponding to the M second MCSs, that modulation order corresponds to one or more modulation schemes.

[0188] For example, when the modulation order corresponding to MCS#1 is 3, MCS#1 can correspond to one or more of 8-QAM, 8-P-QAM, and 8-PSK. The constellation diagram corresponding to 8-P-QAM can be composed of 8 constellation points from the constellation diagram corresponding to 16-QAM, such as... Figure 7 As shown in (a), the constellation diagram corresponding to 8-P-QAM is formed by the eight constellation points indicated by the dashed boxes in the 16-QAM constellation diagram.

[0189] When the modulation order corresponding to MCS#1 is 4, MCS#1 can correspond to one or more of 16-QAM, 16-P-QAM, and 16-PSK. The constellation diagram corresponding to 16-P-QAM can be composed of 16 constellation points from the constellation diagram corresponding to 32-QAM, such as... Figure 7 As shown in (b), the constellation diagram corresponding to 16-P-QAM is composed of 16 constellation points indicated by the dashed boxes in the 32-QAM constellation diagram.

[0190] When the modulation order corresponding to MCS#1 is 5, MCS#1 can correspond to one or more of the following: 32-QAM, at least one 32-P-QAM, amplitude phase shift keying (APSK), and digital video broadcasting (DVB). The constellation diagram corresponding to 32-P-QAM can be composed of 32 constellation points from the constellation diagram corresponding to 64-QAM. At least one 32-P-QAM has a different constellation diagram for each 32-P-QAM, for example... Figure 5 as well as Figure 7 (c) shows the constellation diagrams for two types of 32-P-QAM, with the 32 constellation points in the dashed box forming the constellation diagram corresponding to 32-P-QAM.

[0191] Optionally, MCS#1 corresponds to a modulation scheme. When MCS#1 corresponds to a modulation scheme, that modulation scheme is suitable for modulation and coding processing of inductive signals.

[0192] For example, when the modulation order corresponding to MCS#1 is 3, MCS#1 can correspond to 8-P-QAM; when the modulation order corresponding to MCS#1 is 4, MCS#1 can correspond to 16-P-QAM; and when the modulation order corresponding to MCS#1 is 5, MCS#1 can correspond to 32-P-QAM. The terms 8-P-QAM, 16-P-QAM, and 32-P-QAM are described above.

[0193] In other words, when MCS#1 corresponds to a modulation scheme, if the modulation order of MCS#1 is equal to that of MCS#2, the modulation scheme of MCS#1 is more suitable for modulation and coding processing of sensing signals compared to the modulation scheme of MCS#2 at that modulation order. For example, when the modulation order is 4, the 16-P-QAM modulation scheme of MCS#1 is more suitable for modulation and coding processing of sensing signals than the 16-QAM modulation scheme of MCS#2. In other words, modulation and coding processing based on 16-P-QAM is more conducive to improving the performance of communication and sensing.

[0194] Optionally, the modulation scheme corresponding to a portion of the modulation orders of the M second MCSs can be applied to the modulation coding processing of the sensing signal.

[0195] For example, when the modulation order is 2, the corresponding modulation scheme is QPSK. QPSK can be applied to the modulation and coding processing of inductive signals.

[0196] For example, when the modulation order is 6, the corresponding modulation scheme is 64-QAM. 64-QAM can be applied to the modulation and coding processing of inductive signals.

[0197] That is, for a modulation order that exists in the existing MCS table, if the corresponding modulation method can be applied to the modulation and coding processing of the inductive signal, no new MCS needs to be added for that modulation order.

[0198] It should be understood that in this application, the modulation order refers to the number of bits mapped to a single symbol. For example, as shown in Table 1, if the modulation order Q... m A value of 6 indicates that 6 bits are mapped to a single symbol. Furthermore, the modulation order can also be understood as the number of symbols used for information transmission in a given modulation scheme. For example, in 64-QAM, the number of symbols used for information transmission is 64, meaning the modulation order is 64. In this case, the modulation order can be determined by the number of bits mapped to a single symbol. For instance, in 64-QAM, if 6 bits are mapped to a single symbol, the corresponding modulation order is 2. 6 =64. Unless otherwise specified, the modulation order in this application refers to the former, and the following omits the description of the same or similar cases.

[0199] This application does not limit the specific method of adding new MCSs (i.e., N first MCSs).

[0200] For example, a new MCS can be added to the reserved position in the existing MCS table. For instance, a new MCS can be added to the row corresponding to index 30 in Table 1. That is, the modulation order corresponding to the new MCS is 4. It can be understood that the modulation mode corresponding to the new MCS can include at least one of 16-QAM, 16-P-QAM, and 16-PSK, or the modulation mode corresponding to the new MCS is 16-P-QAM.

[0201] For example, the newly added MCSs can be inserted into the existing table in ascending order of modulation order, as shown in Table 4.

[0202] In the examples above, the first type of MCS table includes all the MCS in the existing tables. Optionally, the first type of MCS table may also include some of the MCS in the existing tables, such as the MCS corresponding to some modulation orders in Table 1. This is not limited.

[0203] Furthermore, there are no restrictions on the code rate (i.e., target code rate × 1024) and spectral efficiency corresponding to the newly added MCS. For example, the target code rate can range from (0, 1), such as 1 / 3, 1 / 2, 2 / 3, 3 / 4, and 15 / 16; correspondingly, the code rate can range from (0, 1024). For multiple code rates corresponding to the same modulation order, these code rates can increase as the index value increases. For example, in Table 4, the code rates corresponding to modulation order 3 increase sequentially from index 10 to 19. The spectral efficiency can be determined based on the corresponding code rate and modulation order. For example, the spectral efficiency is the product of the corresponding modulation order and the code rate, or it can be an approximation of the product of the corresponding modulation order and the code rate.

[0204] Optionally, for MCSs with the same index in the first type of MCS table, the bitrates corresponding to MCSs in different tables can be different. For example, for the MCS corresponding to index 10, the bitrate corresponding to index 10 in Table 4 can be greater than or less than the bitrate corresponding to index 10 in other MCS tables in the first type of MCS table.

[0205] Table 4

[0206]

[0207]

[0208] In Table 4, the MCSs corresponding to indices 10-19 and 27-36 are newly added MCSs (i.e., the first MCS), the MCSs corresponding to indices 0-9, 20-26, and 37-48 are the MCSs included in Table 1 (i.e., the second MCS), and indices 49-63 are reserved. "-" indicates that the code rate or spectral efficiency corresponding to the MCS is not shown. The code rate value corresponding to the MCS can be obtained by combining the code rate range given above and simulation experiments.

[0209] It should be understood that Table 4 is only one form of the first type of MCS table. This first type of MCS table can also take other forms. For example, the number or position of the rows corresponding to newly added MCSs in Table 4 can be adjusted; or, for example, new MCSs corresponding to other modulation orders can be added to Table 4. The composition of the first type of MCS table is described above and will not be listed here. Unless otherwise specified, the newly added MCSs mentioned above refer to the MCSs added to the existing MCS table for modulation and coding processing of the sensing signal.

[0210] Furthermore, using a table to illustrate MCS is just one implementation method; MCS can also exist in the form of text or strings, without limitation.

[0211] Optionally, the transmitting device indicates a first MCS table to the receiving device. That is, when the first type of MCS table includes multiple MCS tables, the transmitting device indicates to the receiving device which MCS table in the first type of MCS table is being used. Further, the transmitting device indicates the index corresponding to the first MCS in the first MCS table through the aforementioned first indication information.

[0212] For example, the transmitting device indicates the first MCS table through higher-layer parameters (e.g., MCS-table, an example of the second indication information). For instance, when the higher-layer parameter MCS-table is configured as 'qam256', it indicates the use of the MCS table obtained based on Table 2. Here, the MCS table obtained based on Table 2 can be understood as an MCS table obtained by adding the first MCS to Table 2, that is, the first type of MCS table includes the MCS table obtained based on Table 2.

[0213] Furthermore, the transmitting device indicates the index of the first MCS in the first MCS table through the MCS indicator field (an example of the first indicator information) in the downlink control information (DCI). The MCS indicator field occupies more than 5 bits, for example, 6 bits, that is, the maximum value of the index that the MCS indicator field can indicate is 63 (the index number starts from 0).

[0214] Based on the above scheme, during signal transmission, the transmitting and receiving devices can select an MCS suitable for sensing signals from the first type of MCStable to perform modulation and coding processing on the signals, thereby improving the performance of communication and sensing.

[0215] For the second possible implementation, the second type of MCS table can be understood as one or more newly designed MCS tables, where each newly designed MCS table can be composed of multiple first MCSs. That is, in addition to the MCS tables in the existing standards, one or more MCS tables for modulation and coding processing of inductive signals can also be designed.

[0216] For example, in the second type of MCS table, the modulation order corresponding to an MCS can be 2, 3, 4, 5, or 6. Each MCS in the second type of MCS table can correspond to one or more modulation schemes.

[0217] Taking the second type of MCS table, including MCS#3, as an example, when the modulation order corresponding to MCS#3 is 2, the modulation scheme corresponding to MCS#3 can be QPSK. That is, QPSK can be applied to the modulation and coding processing of inductive signals.

[0218] When the modulation order corresponding to MCS#3 is 3, MCS#3 can correspond to one or more of 8-QAM, 8-P-QAM, and 8-PSK, or MCS#3 can correspond to 8-P-QAM. For 8-P-QAM, please refer to the description in the first implementation.

[0219] When the modulation order corresponding to MCS#3 is 4, MCS#3 can correspond to one or more of 16-QAM, 16-P-QAM, and 16-PSK, or MCS#3 can correspond to 16-P-QAM. The 16-P-QAM implementation is described in the first implementation.

[0220] When the modulation order corresponding to MCS#3 is 5, MCS#3 can correspond to one or more of 32-QAM, at least one 32-P-QAM, APSK, and DVB; or, MCS#3 can correspond to any one of at least one 32-P-QAM. The 32-P-QAM is described in the first implementation.

[0221] When the modulation order corresponding to MCS#3 is 6, the modulation mode corresponding to MCS#3 is 64-QAM, that is, 64-QAM can be applied to the modulation and coding processing of inductive signals.

[0222] Similarly, no restrictions are placed on the bitrate (i.e., target bitrate × 1024) and spectral efficiency corresponding to the MCS in the second type of MCS table. Refer to the description in the first implementation for details.

[0223] Table 5 shows an example of the second type of MCS table.

[0224] Table 5

[0225]

[0226]

[0227] In Table 5, the MCSs corresponding to indices 0-28 can be used for modulation and coding of inductive signals. "-" indicates that the code rate or spectral efficiency corresponding to the MCS is not shown. The value of the code rate corresponding to the MCS can be obtained by combining the code rate range mentioned above and simulation experiments.

[0228] It is understood that Table 5 is only one form of the second type of MCS table, and this second type of MCS table can also be in other forms. For example, the modulation order in Table 5 can be increased or decreased; for another example, the number of rows corresponding to each modulation order in Table 5 can be adjusted, which will not be listed here.

[0229] Optionally, the transmitting device indicates a first MCS table to the receiving device, and indicates the index corresponding to the first MCS in the first MCS table through first indication information.

[0230] In one example, the sending device indicates a first MCS table via indication information #1 (an example of a third indication information). Indication information #1 indicates that the first MCS table is one of a second type of MCS table and a third type of MCS table. The third type of MCS table refers to the MCS tables in the existing standards (e.g., Table 1, Table 2, and Table 3).

[0231] For example, the transmitting device indicates the first MCS table via higher-level parameters (e.g., MCS-table, an example of indication information #1). The MCS-table can be carried in the PDSCH configuration and / or SRS configuration (e.g., SPSconfig). When the MCS-table is configured as 'ISACComm' or 'ISACSens', it indicates the use of the MCS table shown in Table 5 (an example of the first MCS table); the MCS-table can also be configured as 'qam256' or 'qam64LowSE', or left unconfigured, in which case it can indicate the use of an existing standard MCS table (e.g., Table 1, Table 2, or Table 3).

[0232] In another example, the sending device indicates that the first MCS table belongs to the second type of MCS table through indication information #2, and indicates that the first MCS table is one of the second type of MCS tables through indication information #3.

[0233] For example, the transmitting device indicates that the first MCS table belongs to the second type of MCS table by using one bit in the DCI (an example of the first field), such as by indicating that the first MCS table belongs to the second type of MCS table by the value of that bit being either "0" or "1". Optionally, when the value of that bit is either "0" or "1", it indicates that the MCS table used belongs to the third type of MCS table, which refers to the first example.

[0234] In this example, for indication #3, the existing configuration of the high-level parameter MCS-table can be reused. For example, when the high-level parameter MCS-table is configured as 'qam256' or 'qam64LowSE', it can indicate the use of the MCStable shown in Table 5 (an example of the first MCS table).

[0235] In other words, the transmitting device can use 1 bit in the DCI to indicate whether the MCS table it is using belongs to the second type of MCS table or the third type of MCS table. Furthermore, the transmitting device can use the higher-layer parameter MCS-table to indicate whether the MCS table it is using belongs to a specific type of second-class MCS table or a specific type of third-class MCS table.

[0236] It should be understood that there are no restrictions on the selection of the 1 bit in the above DCI, or on the specific indication method of the indication information #2. For example, the 1 bit can be a newly added bit in the DCI, that is, the indication information #2 can explicitly indicate that the first MCStable belongs to the second type of MCS table or the third type of MCS table; or, a bit in the existing DCI can be reused to implicitly indicate that the first MCS table belongs to the second type of MCS table or the third type of MCS table.

[0237] In another example, the transmitting device can also indicate whether the MCS table used belongs to the second type or the third type of MCS table by the resource configuration method corresponding to the signal to be transmitted.

[0238] For example, if the resource configuration method corresponding to the signal to be transmitted is resource configuration based on resource element (RE) granularity, or in other words, the resource configuration for the signal to be transmitted is indicated by RE as granularity, then the MCS table used (i.e. the first MCS table) belongs to the second type of MCS table.

[0239] If the resource configuration method corresponding to the signal to be transmitted is resource configuration based on resource block (RB) granularity, or in other words, the resource configuration for the signal to be transmitted is indicated by RB as the granularity, then the MCS table used (i.e. the first MCS table) belongs to the third type of MCS table.

[0240] This application does not limit the specific resource allocation method. For example, a bitmap can be used to indicate the allocation of REs or RBs; another example is that the allocated REs (RBs) can be indicated by indicating the starting RE (RB) and the number of consecutive REs (RBs).

[0241] Furthermore, the transmitting device indicates the index of the first MCS in the first MCS table through the MCS indicator field (an example of the first indicator information) in the DCI. In this implementation, the number of bits occupied by the MCS indicator field refers to existing related descriptions. That is, compared to indicating the index corresponding to the first MCS in the first type of MCS table, indicating the index corresponding to the first MCS in the second type of MCS table does not require changes to the existing MCS indicator field in the DCI, thus better compatibility with existing MCS indicator methods.

[0242] Based on the above scheme, during signal transmission, the transmitting and receiving devices can select an MCS suitable for sensing signals from the second type of MCStable to perform modulation and coding processing on the signals, thereby improving the performance of communication and sensing.

[0243] Optionally, in the above two implementation methods, when there are multiple modulation schemes corresponding to the first MCS, the transmitting device can also indicate one of the multiple modulation schemes.

[0244] For example, if the receiving device is configured with constellation diagrams corresponding to multiple modulation schemes, the transmitting device can indicate one of these constellation diagrams using a field in the DCI (an example of the second field). Similarly, there are no restrictions on the selection of the second field or the specific indication method of the second field.

[0245] Optionally, the constellation diagram corresponding to one or more modulation schemes of the first MCS can be configured by the transmitting device through configuration information (an example of the second configuration information). For example, this configuration information is carried in radio resource control (RRC) signaling, media access control (MAC) signaling, or other downlink signaling.

[0246] S620, the transmitting device transmits data signals to the receiving device based on the first MCS.

[0247] For example, the transmitting device can perform modulation and coding processing on the data signal according to the modulation scheme and code rate corresponding to the first MCS, and send the modulated and coded signal to the receiving device. Correspondingly, after receiving the modulated and coded signal, the receiving device can perform demodulation and decoding processing on the received signal according to the first MCS.

[0248] Based on the above scheme, during signal transmission, the transmitting and receiving devices can select an MCS suitable for sensing signals to perform modulation and coding processing on the signals, thereby improving the performance of communication and sensing.

[0249] It is understood that in the above embodiments, the term "transmission" is used. Unless otherwise specified, transmission includes receiving and / or sending. For example, transmitting a signal may include receiving a signal and / or sending a signal.
