Description

Communication method and communication apparatus

[0001] This application claims priority to the Chinese Patent Application No. 202410711084.3, filed on June 3, 2024, and entitled "Communication method and communication apparatus", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] The present application relates to the field of communication technology, and more particularly, to a communication method and a communication apparatus. BACKGROUND

[0003] Both wireless communication and wireless sensing are based on electromagnetic wave theory. The transmitter modulates the electromagnetic wave signal to make the electromagnetic wave carry the source information. The electromagnetic wave signal is affected by the wireless environment during transmission, that is, the electromagnetic wave signal is modulated by the environment and therefore also carries environmental information. The receiver can not only obtain the carried source information, but also extract sensing information reflecting the characteristics of the propagation environment through analysis of the electromagnetic wave signal, which makes it possible to integrate sensing and communication (ISAC).

[0004] In order to match different wireless channel conditions, new radio interface (NR) supports multiple modulation coding schemes (MCS) to modulate and encode signals. Different MCSs correspond to different combinations of modulation order and coding rate, and different modulation orders can correspond to different modulation methods, for example, the modulation methods include quadrature phase shift keying (QPSK) modulation and quadrature amplitude modulation (QAM). In the communication scenario, using a higher modulation order can improve the transmission rate of information, while in the ISAC scenario, while improving the transmission rate of information, the sensing performance also needs to be considered. For sensing, it is desirable to reduce the modulation order to improve the anti-interference ability of signal transmission. Therefore, in the ISAC scenario, how to determine the appropriate MCS to achieve better communication and sensing performance is a problem to be solved. SUMMARY

[0005] The present application provides a communication method and a communication apparatus, which can select appropriate MCS to improve the performance of communication and sensing.

[0006] In a first aspect, a communication method is provided, which can be applied to a transmitting device. In the present disclosure, the "transmitting device" can refer to the transmitting device itself (e.g., a network device, a terminal device), a component (e.g., a processor, a chip, or a chip system) in the transmitting device, or a logic module or software capable of implementing all or part of the functions of the transmitting device.

[0007] The method comprises: transmitting 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 a communication and sensing integrated signal, the first MCS corresponding to one or more modulation modes; and transmitting a data signal according to the first MCS.

[0008] Based on the above scheme, the transmitting device and the receiving device can transmit data signals according to the MCS used for the modulation and coding processing of the communication and sensing integrated signal, which can improve the performance of communication and sensing. In addition, the MCS used for the modulation and coding processing of the communication and sensing integrated signal corresponding to one or more modulation modes can improve the flexibility of modulation mode selection.

[0009] In some implementations of the first aspect, the first MCS belongs to a first MCS table, and the first MCS table belongs to a first type of MCS table, the first type of MCS table further comprising a plurality of second MCSs, the second MCSs being used for modulation and coding processing of a communication signal.

[0010] Based on the above scheme, by including the first MCS and the second MCS in the first type of MCS table, the selection of MCSs for different signals (e.g., a communication signal or a communication and sensing integrated signal) can be more flexible.

[0011] In some implementations of the first aspect, the first type of MCS table comprises a plurality of MCS tables, the plurality of MCS tables having different code rates corresponding to the same modulation order, and the method further comprises: transmitting second indication information, the second indication information indicating the first MCS table, the first MCS table being one of the plurality of MCS tables.

[0012] Based on the above scheme, the transmitting device can select a suitable MCS table from the first type of MCS table according to different code rates.

[0028] Based on the above scheme, the flexibility of the transmitting end device to select a modulation mode with a modulation order of 3 can be increased, and by configuring the modulation mode corresponding to the first MCS to include at least one of 8-PSK and 8-P-QAM, the performance of communication and perception can be improved.

[0103] The technical solutions in the present application will be described below with reference to the accompanying drawings.

[0104] FIG. 1 is a schematic architecture diagram of a communication system to which the embodiments of the present application are applied. As shown in FIG. 1, the communication system includes a radio access network (RAN) 100. Optionally, the communication system can also include a core network 200 and an Internet 300.

[0105] The RAN 100 can include at least one RAN node (e.g., 110a and 110b in FIG. 1, collectively referred to as 110) and at least one terminal (e.g., 120a-120j in FIG. 1, collectively referred to as 120). The RAN 100 can also include other RAN nodes, such as a wireless relay device and / or a wireless backhaul device (not shown in FIG. 1). The terminals 120 are connected to the RAN nodes 110 in a wireless manner. Terminals and terminals, and RAN nodes and RAN nodes, can be connected to each other in a wired or wireless manner. The RAN nodes 110 are connected to the core network 200 in a wireless or wired manner. The core network devices in the core network 200 and the RAN nodes 110 in the RAN 100 can be independent and different physical devices, or can be the same physical device integrated with part or all of the logical functions of the core network devices and part or all of the logical functions of the RAN nodes.

[0106] The RAN 100 can be an evolved universal terrestrial radio access (E-UTRA) system, a NR system, a 6th generation (6G) wireless access system, and a future wireless access system defined in the 3rd generation partnership project (3GPP), and can also be a wireless fidelity (WiFi) system. The RAN 100 can also include two or more different wireless access systems described above. The RAN 100 can also be an open RAN (O-RAN).

[0107] The RAN node, also referred to as a radio access network device, RAN entity, or access node, is used to help terminals access the communication system through wireless means. In an application scenario, the RAN node can be a base station, an evolved NodeB (eNodeB), a transmission reception point (TRP), a next generation NodeB (gNB) in a 5th generation (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. The RAN node can be a macro base station (such as 110a in FIG. 1), or a micro base station or indoor station (such as 110b in FIG. 1), and can also be a relay node or a donor node.

[0108] In another application scenario, wireless access can be achieved for a terminal through cooperation of multiple RAN nodes, and different RAN nodes respectively implement part of functions of a base station. For example, a RAN node can be a central unit (CU), or a distributed unit (DU) or a radio unit (RU). Here, the CU completes functions of a radio resource control protocol and a packet data convergence protocol (PDCP) of a base station, and can also complete a function of a service data adaptation protocol (SDAP); the DU completes functions of a radio link control layer and a medium access control (MAC) layer of a base station, and can also complete part of a physical layer or all of a physical layer; and specific descriptions about the above protocol layers can be referred to related technical specifications of 3GPP. The RU can be used to implement functions of transceiving a radio frequency signal. The CU and the DU can be two independent RAN nodes, or can be integrated in a same RAN node, for example, integrated in a baseband unit (BBU). The RU can be included in a radio frequency device, for example, included in a remote radio unit (RRU) or an active antenna unit (AAU). The CU can be further divided into two types of RAN nodes of a CU-control plane and a CU-user plane.

[0109] In different systems, the RAN node can have different names. For example, in an O-RAN system, the CU can also be referred to as an open CU (O-CU), the DU can also be referred to as an open DU (O-DU), and the RU can be referred to as an open RU (O-RU). In this application, the RAN node can be implemented through a software module, a hardware module, or a combination of a software module and a hardware module. For example, the RAN node can be a server loaded with a corresponding software module. Embodiments of this application do not limit the specific technology and specific device form of the RAN node. For ease of description, a network device or a base station is taken as an example of the RAN node below.

[0110] The terminal can be a device with wireless transceiving function, and can send signals to the base station or receive signals from the base station. The terminal can also be referred to as a terminal device, user equipment (UE), mobile station, mobile terminal, etc. The terminal can be widely applied to 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, automatic driving, remote medical treatment, smart power grid, smart furniture, smart office, smart wear, smart transportation, smart city, etc. The terminal can be a mobile phone, tablet computer, computer with wireless transceiving function, wearable device, vehicle, airplane, ship, robot, mechanical arm, smart home device, etc. Embodiments of the present application do not limit the specific technology and specific device form of the terminal.

[0111] The base station and the terminal can be fixed in position or movable. The base station and the terminal can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; can also be deployed on water surface; can also be deployed on airplanes, balloons and artificial satellites. Embodiments of the present application do not limit the application scenarios of the base station and the terminal.

[0112] The roles of the base station and the terminal can be relative, for example, the helicopter or unmanned aerial vehicle 120i in FIG. 1 can be configured as a mobile base station, and for those terminals 120j accessing the wireless access network 100 through 120i, the terminal 120i is a base station; but for the base station 110a, 120i is a terminal, that is, 110a and 120i communicate through a wireless air interface protocol. Of course, 110a and 120i can also communicate through a base station-to-base station interface protocol, at this time, relative to 110a, 120i is also a base station. Therefore, the base station and the terminal can be collectively referred to as a communication device, 110a and 110b in FIG. 1 can be referred to as a communication device with base station function, and 120a-120j in FIG. 1 can be referred to as a communication device with terminal function.

[0113] The base station and the terminal, the base station and the base station, and the terminal and the terminal can communicate through licensed spectrum, unlicensed spectrum, or both licensed spectrum and unlicensed spectrum; can communicate through spectrum below 6 gigahertz (GHz), spectrum above 6 GHz, or both spectrum below 6 GHz and spectrum above 6 GHz. Embodiments of the present application do not limit the spectrum resources used for wireless communication.

[0114] In the embodiments of the present application, the functions of the base station can also be performed by a module (such as a chip) in the base station, or by a control subsystem containing the functions of the base station. The control subsystem containing the functions of the base station herein can be a control center in the above-mentioned application scenarios such as smart grid, industrial control, intelligent transportation, and smart city. The functions of the terminal can also be performed by a module (such as a chip or modem) in the terminal, or by a device containing the functions of the terminal.

[0115] In the present application, the base station transmits a downlink signal or downlink information to the terminal, and the downlink information is carried on a downlink channel; the terminal transmits an uplink signal or uplink information to the base station, and the uplink information is carried on an uplink channel. In order for the terminal to communicate with the base station, the terminal needs to establish a wireless connection with a cell controlled by the base station. The cell that establishes a wireless connection with the terminal is called the service cell of the terminal.

[0116] As an example, the RAN node can be a satellite base station, which is described below in connection with FIG. 2.

[0117] FIG. 2 is a schematic diagram of an application scenario to which the present application is applicable. As shown in (a) and (b) of FIG. 2, a satellite base station provides communication services for a terminal. For example, the satellite base station transmits downlink data to the terminal, wherein the data is encoded using channel coding, and the encoded data is transmitted to the terminal after being subjected to constellation modulation. For another example, the terminal transmits uplink data to the satellite base station, and the uplink data can also be encoded using channel coding, and the encoded data is transmitted to the satellite base station after being subjected to constellation modulation. In addition, as shown in (b) of FIG. 2, the satellite base station can also communicate with a ground base station, i.e., the satellite can act as a base station, and also as a terminal.

[0118] In the present application, the satellite can refer to a drone, a hot air balloon, a low-orbit satellite, a medium-orbit satellite, a high-orbit satellite, etc. The satellite can also refer to a non-ground base station or a non-ground device, etc.

[0119] It should be understood that the present application can be applied to a scenario in which network devices communicate with each other, and the scenario shown in (b) of FIG. 2 can also be regarded as an example of network devices communicating with each other, wherein the satellite and the base station can both be regarded as a network device.

[0120] As an implementation manner, the present application can be applied to a satellite inter-satellite link communication system.

[0121] As shown in (c) of FIG. 2, the satellite inter-satellite link communication system can be divided into two parts: an acquisition pointing tracking (APT) subsystem and a communication subsystem. Among them, the communication subsystem is mainly responsible for the transmission of inter-satellite information, and the communication subsystem is the main part of the inter-satellite communication system; the APT system is mainly responsible for the acquisition, alignment and tracking between satellites. Among them, the direction of arrival of the incident signal can be determined, which is used for acquisition, and the direction of the transmitted wave is adjusted to aim at the receiving direction, which is used for alignment. In the whole communication process, the alignment and acquisition are constantly adjusted for tracking. In order to reduce the influence of attenuation and interference in the channel as much as possible, while requiring high confidentiality and transmission rate, the APT system must be adjusted in real time to constantly adapt to changes.

[0122] It should be understood that the current APT system is an optical system, which has the disadvantage of difficult optical alignment and the need for mechanical adjustment of the pointing direction. The existing communication subsystem is mostly an optical communication system, and there are also some microwave band systems, mostly using a single high-gain antenna. The existing APT system and communication subsystem are independent systems. The disadvantage is that optical communication is easily affected by vibration and the like, and the rate is unstable; the frequency of millimeter waves is low, the communication capacity is low, and the antenna needs to be mechanically adjusted to point.

[0123] As another example, the RAN node can be a station (STA), which is explained below in connection with FIG. 3.

[0124] FIG. 3 is a schematic diagram of another application scenario to which the present application is applicable. As shown in FIG. 3, the resource configuration method provided by the present application is applicable to data communication between stations, where the stations can be access point (AP) type stations or non-AP type stations (non-AP STA), which are referred to as AP and non-AP stations for short, respectively. Specifically, the scheme of the present application is applicable to data communication between an AP and one or more non-AP stations (for example, data communication between AP1 and non-AP STA1, non-AP STA2), applicable to data communication between an AP and an AP (for example, data communication between AP1 and AP2), and applicable to data communication between non-AP stations (for example, data communication between non-AP STA2 and non-AP STA3).

[0125] The access point can be an access point for a terminal (e.g., a mobile phone) to enter a wired (or wireless) network, and is mainly deployed in a home, a building, and a campus, and has a typical coverage radius of tens of meters to hundreds of meters, and can also be deployed outdoors. The access point is equivalent to a bridge connecting a wired network and a wireless network, and mainly functions to connect various wireless network clients together and then access the wireless network to an Ethernet.

[0126] Specifically, the access point can be a terminal or a network device with a Wi-Fi chip, and the network device can be a server, a router, a switch, a bridge, a computer, a mobile phone, a relay station, a vehicle-mounted device, a wearable device, a network device in a 5G network, a network device in a future 6G network, or a network device in a public land mobile network (PLMN), etc. The access point can be a device supporting a Wi-Fi standard. For example, the access point can also support one or more standards of the Institute of Electrical and Electronics Engineers (IEEE) 802.11 family, such as 802.11a, 802.11b, 802.11g, 802.11n, 802.11ac, 802.11ax, 802.11be, 802.11ad, 802.11ay, etc.

[0127] The non-AP station can be a wireless communication chip, a wireless sensor, or a wireless communication terminal, and can also be referred to as a user, a user equipment (UE), an access terminal, a subscriber unit, a subscriber station, a mobile station, a mobile, a remote station, a remote terminal, a mobile device, a user terminal, a terminal, a wireless communication device, a user agent, or a user device. The non-AP station can be a cellular phone, a cordless phone, a session initiation protocol (SIP) phone, a wireless local loop (WLL) station, a personal digital assistant (PDA), a handheld device with wireless communication function, a computing device, or other processing device connected to a wireless modem, an in-vehicle device, an Internet of Things device, a wearable device, a terminal device in a 5G network, a terminal device in a future 6G network, or a terminal device in a PLMN, etc. The non-AP station can be a device supporting a WLAN standard. For example, the non-AP station 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, 802.11ay, etc.

[0128] For example, the non-AP station can be a mobile phone, a tablet computer, a set-top box, a smart television, a smart wearable device, an in-vehicle communication device, a computer, an Internet of Things (IoT) node, a sensor, a smart home device such as a smart camera, a smart remote controller, a smart water meter, and a sensor in a smart city, etc.

[0129] The AP or non-AP station described above can include a transmitter, a receiver, a memory, a processor, etc., where the transmitter and the receiver are respectively used for transmission and reception of packet structures, the memory is used to store signaling information and store preset values agreed in advance, etc., and the processor is used to analyze signaling information, process related data, etc.

[0130] The communication system to which the present application is applied is only illustrative, and the communication system to which the present application is applied is not limited thereto.

[0131] For the convenience of understanding the embodiments of the present application, some basic concepts related to the present application are briefly described.

[0132] 1. Perception

[0133] The technical principle of sensing is different from that of communication. In communication, the sending end modulates information on radio waves and sends it to the receiving end, and the receiving end demodulates the signal carried on the radio waves to obtain the information. In sensing, the sending end sends radio waves in a specific direction, and when the radio waves irradiate the target surface, reflected waves are formed, so that the receiving end obtains the position, speed and type of the target by receiving and processing the reflected waves.

[0134] A sensing signal refers to a signal used for sensing a target or detecting a target, or in other words, a signal used for sensing environmental information or detecting environmental information. For example, the sensing signal is an electromagnetic wave sent by a network device for sensing environmental information. The sensing signal can also be referred to as a radar signal, a radar sensing signal, a detection signal, a radar detection signal, an environmental sensing signal, etc.

[0135] Sensing can be generally divided into two modes: single-station sensing and double-station sensing. In single-station sensing, the sending end and the receiving end of the sensing signal are the same device, and in the processing flow of the sensing signal, the sensing station both sends the sensing signal and receives the signal reflected on the target surface, so the single-station sensing mode is also referred to as self-transmission and self-reception mode. In double-station sensing, the sending end and the receiving end of the sensing signal are different devices, and in the processing flow of the sensing signal, the sensing station A sends the sensing signal, and the signal reflected on the target surface is received by the sensing station B, so the double-station sensing mode is also referred to as A-transmission and B-reception mode.

[0136] 2. Integrated sensing and communication (ISAC)

[0137] Integrated sensing and communication (ISAC) refers to introducing a sensing capability on the basis of supporting mobile communication transmission by a base station. The sensing capability is characterized by “transmission and reception” (i.e., transmitting an excitation signal and detecting and sensing a target by using a reflected signal, which has the same mechanism as a radar).

[0138] FIG. 4 is a schematic diagram of an integrated sensing and communication station. As shown in FIG. 4, the integrated sensing and communication station A both sends a sensing signal (e.g., a sensing excitation signal) and receives a signal (e.g., a sensing reflected signal) reflected on a target surface by the sensing signal, and the integrated sensing and communication station A can also send a communication downlink signal to a target and receive a communication uplink signal sent by the target.

[0139] It should be understood that a station for integrated sensing and communication can be a network device or a terminal device.

[0140] The perceived target can include various tangible objects on the ground that can be perceived, such as landforms, forests, or buildings, and can also include vehicles, unmanned aerial vehicles, terminal devices, and the like. It should be noted that the vehicles, unmanned aerial vehicles, and user equipment (UE) shown in FIG. 4 are only examples, and the perceived target can also include movable objects such as pedestrians, terminal devices (including UEs), and the like, which are not limited in the present application. It should be understood that the communication and perception integrated station A can also communicate with the perceived target (such as an unmanned aerial vehicle, a vehicle), and the like, which is not limited in the present application.

[0141] It should also be understood that the perceived target is a target that can be perceived by a network device with perception function, and the target can feed back an electromagnetic wave to the network device. The perceived target can also be referred to as a detected target, a perceived object, a detected object, or a perceived device, and the like, which is not limited in the present application.

[0142] FIG. 4 shows a communication and perception integrated station in a single station perception mode, and the communication and perception integrated station in a double station perception mode can refer to FIG. 4, which is not described in detail.

[0143] The scenario of FIG. 4 is only an example, and in a possible scenario, the network side can include multiple communication and perception integrated stations, such as three or more communication and perception integrated stations.

[0144] 3, modulation and coding scheme (MCS)

[0145] In the signal processing process, the data signal can be encoded and modulated. In the MCS, the encoding can refer to channel coding, and the modulation can refer to mapping the encoded data into the smallest unit symbol in the time domain resource. In the encoding process, multiple redundant bits can be added for error correction, thereby introducing the concept of code rate. The code rate represents the proportion of effective data in the total data after encoding, for example, if the code rate (which can be represented by a symbol R) is equal to 3 / 4, it means that 3 / 4 of the data after encoding is effective data, and the remaining 1 / 4 of the data is a redundant bit.

[0146] Different code rates and different modulation modes constitute different MCSs. The modulation modes in the existing protocol can include at least one of the following: a binary phase shift keying (BPSK) modulation mode, a quadrature phase shift keying (QPSK) modulation mode, a 16-quadrature amplitude modulation (QAM) mode, a 64-QAM mode, a 256-QAM mode, a 1024-QAM mode, or a 4096-QAM mode, and the like. Among them, the number before QAM is 2 raised to the power of n, n is a positive integer, and n can be used to represent the number of bits mapped by a single symbol.

[0147] 4. Modulation and coding strategy table (MCS table)

[0148] The MCS table can be used to indicate the correspondence between different modulation modes (such as QPSK, 16-QAM, 64-QAM, 256-QAM, etc.) and code rates.

[0149] The MCS table allows the network side and the terminal side to flexibly select a suitable modulation and coding scheme as needed. In the downlink (for example, PDSCH) and the uplink (for example, physical uplink shared channel (PUSCH)), the UE and the RAN will select a suitable MCS index in the MCS table based on channel conditions, traffic requirements, and other factors, to determine the specific modulation mode and code rate.

[0150] Taking new radio (NR) as an example, three MCS tables are predefined for PDSCH, which are Table 1, Table 2, and Table 3. Among them, Table 1 is a high spectral efficiency MCS table with a highest modulation order of 6, Table 2 is an MCS table with a highest modulation order of 8, and Table 3 is a low spectral efficiency MCS table with a highest modulation order of 6. Each table contains multiple MCS indexes, each of which corresponds to a specific modulation mode and coding rate (target code rate x 1024).

[0151] Table 1

[0152] Table 2

[0153] Table 3

[0154] For example, in Table 1, the first column is the MCS index I MCS , where indexes 29-31 are reserved bits; the second column is the modulation order Q m , which represents the modulation mode, i.e., a value of the modulation order corresponds to a modulation mode, for example, when Q m = 2, the corresponding modulation mode is QPSK; when Q m = 4, the corresponding modulation mode is 16-QAM; and when Q m = 6, the corresponding modulation mode is 64-QAM. The third column is the code rate, which represents the code rate expected to be achieved after selecting the modulation mode corresponding to the MCS index and the corresponding redundancy; and the fourth column is the spectral efficiency, which represents the frequency efficiency corresponding to the MCS index. The spectral efficiency is positively correlated with the code rate, i.e., the higher the code rate, the higher the spectral efficiency.

[0155] The sending end device can indicate the receiving end device to use which predefined MCS table through a high-level parameter (for example, MCS-table), and then indicate the index of the used MCS in the MCS table through the MCS indication field in the downlink control information (DCI).

[0156] 4. Pruned quadrature amplitude modulation (QAM) (P-QAM):

[0157] In the existing 5G symbol modulation, modulation modes such as quadrature phase shift keying (QPSK), 16-quadrature amplitude modulation (16-QAM), and 64-quadrature amplitude modulation (64-QAM) are supported, which can match different channel conditions and obtain better transmission rates under corresponding channel conditions. However, for perception, under the corresponding channel conditions, the modulation modes similar to 16-QAM and 64-QAM are not optimal, and therefore, a P-QAM modulation scheme, i.e., pruned QAM, or a new P-QAM constellation diagram formed by selecting some constellation points on the original QAM constellation diagram, is proposed.

[0158] For example, FIG. 5 shows a schematic diagram of a 32-P-QAM constellation. As shown in FIG. 5, a 64-QAM constellation is composed of 64 constellation points, and the constellation points in the dashed box are selected from the 64 constellation points to form a 32-P-QAM constellation. The 32-P-QAM is a 5-bit modulation mode, that is, a single symbol is mapped to 5 bits. I and Q represent in-phase (I) and quadrature (Q) components, respectively.

[0159] It should be understood that x in the above x-QAM or x-P-QAM represents the number of symbols used for information transmission in the modulation mode, which can also be referred to as the modulation order. The modulation order can be determined by the number of bits mapped to a single symbol in the modulation mode. For example, if a single symbol is mapped to 6 bits, the corresponding modulation order is 26 6 = 64.

[0160] It should also be understood that the constellation corresponding to the modulation mode can represent the distribution of the symbols used for information transmission in the complex plane under the modulation mode. Specifically, each constellation point on the constellation represents a symbol, which has a specific amplitude and phase. For example, in 64-QAM, there are 64 points on the constellation because there are 64 different symbols. These points are represented by the components of the I axis (real part) and the Q axis (imaginary part), which represent the amplitude adjustment on the two orthogonal carriers, respectively. The distance of the constellation point to the origin represents the amplitude after modulation, and the angle of the constellation point with the positive direction of the real axis represents the phase after modulation.

[0161] In a communication scenario, the transmission rate of information can be improved by using an MCS with a high modulation order that matches the channel condition. Under the same channel condition, it is expected to reduce the modulation order to improve the anti-interference ability of the signal transmission process in terms of perception. Therefore, in the ISAC scenario, how to determine a suitable MCS to meet the performance requirements of communication and perception (referred to as communication and perception) is a problem to be solved.

[0162] In view of this, the present application provides a communication method and a communication device, which can improve the performance of communication and perception by selecting a suitable MCS.

[0163] In order to facilitate the understanding of the embodiments of the present application, the following points are explained before introducing the embodiments of the present application.

[0164] First, the various numerical numbers involved in the embodiments of the present application are only used for differentiation for convenience of description, and do not limit the scope of the embodiments of the present application. The size of the serial number of the above processes does not mean the order of execution, and the execution order of the processes should be determined by their functions and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.

[0165] Secondly, in the embodiments of the present application, "first", "second", and various numerical designations are used for the purpose of distinguishing only and do not limit the scope of the embodiments of the present application. For example, different indication information is distinguished.

[0166] Thirdly, in the embodiments of the present application, the descriptions such as "when", "in the case of", and "if" all refer to the objective situation in which the device will make corresponding processing, and are not limited in time, and do not require the device to have a judgment action when implemented, nor does it mean that there are other limitations.

[0167] FIG. 6 is a schematic diagram of an encoding method 600 provided by the present application.

[0168] It can be understood that the method 600 can be executed by a sending device and a receiving device, and without special description, the "sending device" or "receiving device" can refer to the sending device or the receiving device itself, or can refer to a device capable of supporting the sending device or the receiving device to implement the function, and for the convenience of description, the sending device and the receiving device are used to describe below. 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.

[0169] As shown in FIG. 6, the method includes the following steps.

[0170] S610, the sending device sends first indication information to the receiving device. Correspondingly, the receiving device receives the first indication information.

[0171] The first indication information is used to indicate an index corresponding to a first MCS. The first MCS can be used for modulation and coding processing of a communication and sensing integrated signal, and the first MCS corresponds to one or more modulation modes.

[0172] In the following, for the sake of simplicity, the communication and sensing integrated signal can be referred to as "sensing signal". The sensing signal can refer to a signal used for communication having a sensing function, or a signal used for sensing having a communication function, or a signal only having a sensing function, and the specific use of the function of the signal can be determined according to the actual situation, and is not limited.

[0173] Exemplarily, the index corresponding to the first MCS belongs to a first MCS table. The first MCS table can include a corresponding relationship between at least one index and at least one MCS. That is, the first indication information indicates an index in the first MCS table, and the index has a corresponding relationship with the first MCS.

[0174] Exemplarily, the sending end device can select the first MCS table from at least one MCS table. There can be two implementation manners for the selection of the first MCS table.

[0175] One possible implementation manner is to select the first MCS from the first type of MCS table. The first type of MCS table includes N first MCSs, which are used for the modulation and coding processing of the common sense signal; and the first type of MCS table also includes M second MCSs, which are used for the modulation and coding processing of the communication signal, M and N being positive integers.

[0176] Another possible implementation manner 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, which are used for the modulation and coding processing of the common sense signal, K being a positive integer.

[0177] The following detailed description is made on the two possible implementation manners.

[0178] Specifically, for the first possible implementation manner, the M second MCSs in the first type of MCS table can be understood as one or more MCSs in an existing MCS table.

[0179] For example, the second MCS is any row in Table 1 to Table 3.

[0180] For another example, the second MCS is any row in Table 1 to Table 3, and the index of the row is changed. That is, the newly added N first MCSs can change the index of the MCS in the existing table, but the modulation mode, code rate and spectral efficiency corresponding to the MCS do not change.

[0181] That is, the first type of MCS table can be understood as adding N first MCSs in the existing MCS table to form a new MCS table, wherein the added N first MCSs are used for the modulation and coding processing of the common sense signal.

[0182] Exemplarily, for the first type of MCS table, the modulation order corresponding to one of the newly added N first MCSs (denoted as MCS#1) can or can not be included in the modulation order corresponding to the M second MCSs. For example, the modulation order corresponding to the M second MCSs includes 2, 4, 6 and 8 (the modulation order corresponding to the MCS in Table 1 to Table 3), and the modulation order corresponding to the MCS#1 can be 2, 4, 6 or 8; alternatively, the modulation order corresponding to the MCS#1 can also be 3 or 5.

[0183] In addition, the MCS #1 can correspond to one or more modulation manners. When the modulation order corresponding to the MCS #1 is included in the modulation orders corresponding to the M second MCSs, the MCS #1 can correspond to one or more modulation manners compared with a modulation manner corresponding to a modulation order corresponding to the MCS #1 in the M second MCSs (denoted as MCS #2); when the modulation order corresponding to the MCS #1 is not included in the modulation orders corresponding to the M second MCSs, the modulation order corresponds to one or more modulation manners.

[0184] For example, when the modulation order corresponding to the MCS #1 is 3, the MCS #1 can correspond to one or more of 8-QAM, 8-P-QAM, and 8-PSK. Wherein, the constellation diagram corresponding to the 8-P-QAM can be composed of 8 constellation points in the constellation diagram corresponding to the 16-QAM, as shown in (a) of FIG. 7, the 8 constellation points in the dashed line box in the 16-QAM constellation diagram constitute the constellation diagram corresponding to the 8-P-QAM.

[0185] When the modulation order corresponding to the MCS #1 is 4, the MCS #1 can correspond to one or more of 16-QAM, 16-P-QAM, and 16-PSK. Wherein, the constellation diagram corresponding to the 16-P-QAM can be composed of 16 constellation points in the constellation diagram corresponding to the 32-QAM, as shown in (b) of FIG. 7, the 16 constellation points in the dashed line box in the 32-QAM constellation diagram constitute the constellation diagram corresponding to the 16-P-QAM.

[0186] When the modulation order corresponding to the MCS #1 is 5, the MCS #1 can correspond to one or more of 32-QAM, at least one 32-P-QAM, amplitude phase shift keying (APSK), and digital video broadcasting (DVB). Wherein, the constellation diagram corresponding to the 32-P-QAM can be composed of 32 constellation points in the constellation diagram corresponding to the 64-QAM, the constellation diagram corresponding to each of the at least one 32-P-QAM is different, for example, as shown in FIG. 5 and (c) of FIG. 7 are two constellation diagrams of 32-P-QAM, and the 32 constellation points in the dashed line box constitute the constellation diagram corresponding to the 32-P-QAM.

[0187] Optionally, the MCS #1 corresponds to one modulation manner. When the MCS #1 corresponds to one modulation manner, the modulation manner is applicable to the modulation and coding processing of the sensing signal.

[0188] 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. Among them, 8-P-QAM, 16-P-QAM, and 32-P-QAM refer to the above description.

[0189] That is, when MCS#1 corresponds to a modulation mode, if the modulation order corresponding to MCS#1 is equal to the modulation order corresponding to MCS#2, compared with the modulation mode corresponding to MCS#2 at the modulation order, the modulation mode corresponding to MCS#1 is more suitable for the modulation and coding processing of the sensing signal. For example, when the modulation order is 4, the modulation mode corresponding to MCS#1 is 16-P-QAM, compared with 16-QAM corresponding to MCS#2, 16-P-QAM is more suitable for the modulation and coding processing of the sensing signal, or in other words, the modulation and coding processing based on 16-P-QAM is more conducive to improving the performance of communication and sensing.

[0190] Optionally, for the modulation mode corresponding to part of the modulation orders corresponding to the M second MCSs, it can be suitable for the modulation and coding processing of the sensing signal.

[0191] For example, when the modulation order is 2, the corresponding modulation mode is QPSK. QPSK can be suitable for the modulation and coding processing of the sensing signal.

[0192] For another example, when the modulation order is 6, the corresponding modulation mode is 64-QAM. 64-QAM can be suitable for the modulation and coding processing of the sensing signal.

[0193] That is, for the modulation order existing in the existing MCS table, if the modulation mode corresponding to the modulation order can be suitable for the modulation and coding processing of the sensing signal, a new MCS can not be added for the modulation order.

[0194] It should be understood that in this application, the modulation order refers to the number of bits mapped by a single symbol, for example, as shown in Table 1, if the modulation order Q m is 6, it means that the number of bits mapped by a single symbol is 6. In addition, the modulation order can also be understood as the number of symbols used for information transmission under a certain modulation mode, for example, in 64-QAM, the number of symbols used for information transmission is 64, that is, the modulation order is 64, at this time, the modulation order can be determined by the number of bits mapped by a single symbol, for example, in 64-QAM, the number of bits mapped by a single symbol is 6, and the corresponding modulation order is 2 6 = 64. Unless otherwise specified, the meaning of the modulation order in this application is the former, and the following description of the same or similar cases is omitted.

[0195] The application does not limit the specific way of adding new MCS (i.e. N first MCS).

[0196] For example, new MCS can be added in the reserved bit of the existing MCS table, as shown in Table 1, the new MCS is added in the row corresponding to index 30, and the modulation order of the new MCS is 4. It can be understood that the modulation mode of the new MCS can include at least one of 16-QAM, 16-P-QAM, and 16-PSK, or the modulation mode of the new MCS is 16-P-QAM.

[0197] For another example, the new MCS is inserted into the existing table in the order of modulation order from small to large, as shown in Table 4.

[0198] In the above example, the first type of MCS table includes all the MCSs in the existing table. Alternatively, the first type of MCS table can also include part of the MCSs in the existing table, for example, part of the MCSs corresponding to the modulation order in Table 1, which is not limited.

[0199] In addition, the code rate (i.e. target code rate x 1024) and spectral efficiency of the new MCS are not limited. For example, the value range of the target code rate can be (0, 1), such as the value of the target code rate can include 1 / 3, 1 / 2, 2 / 3, 3 / 4, and 15 / 16; correspondingly, the value range of the code rate can be (0, 1024). For multiple code rates corresponding to the same modulation order, the multiple code rates can increase with the value of the index, for example, the code rates corresponding to the modulation order 3 in Table 4 increase in turn from index 10-19. The spectral efficiency can be determined according to the corresponding code rate and modulation order, for example, the spectral efficiency is the product of the corresponding modulation order and code rate, or the spectral efficiency takes the approximate value of the product of the corresponding modulation order and code rate.

[0200] Alternatively, for the MCSs corresponding to the same index in the first type of MCS table, the code rates of the MCSs in different tables can be different. For example, for the MCS corresponding to index 10, the code rate corresponding to index 10 in Table 4 can be greater than or less than the code rate corresponding to index 10 in other MCS tables in the first type of MCS table.

[0202] In Table 4, indexes 10-19, 27-36 correspond to the newly added MCS (i.e., the first MCS), indexes 0-9, 20-26, 37-48 correspond to the MCS included in Table 1 (i.e., the second MCS), and indexes 49-63 are reserved bits. "-" indicates that the code rate or spectral efficiency corresponding to the MCS is not shown, and the value of the code rate corresponding to the MCS can be obtained in combination with the value range of the code rate given above and simulation experiments.

[0203] It should be understood that Table 4 is only one form of the first type of MCS table, and the first type of MCS table can also be other forms, for example, the number or position of the rows corresponding to the newly added MCS in Table 4 can be adjusted; for another example, other modulation order corresponding newly added MCS is added in Table 4, etc. For the form of the first type of MCS table, refer to the description above, which is not listed one by one here. Unless otherwise specified, the above-mentioned newly added MCS refers to the newly added MCS for modulation and coding processing of the common signal in the existing MCS table.

[0204] In addition, using a table to illustrate the MCS is only one implementation, and the MCS can also exist in the form of text or string, without limitation.

[0205] Optionally, the sending end device indicates the first MCS table to the receiving end device. That is, when the first type of MCS table includes multiple MCS tables, the sending end device indicates to the receiving end device which one of the first type of MCS table is used. Further, the sending end device indicates the index corresponding to the first MCS in the first MCS table through the first indication information.

[0206] For example, the sending end device indicates the first MCS table through a high-level parameter (for example: MCS-table, an example of the second indication information), such as when the high-level parameter MCS-table is configured as 'qam256', it indicates that the MCS table obtained based on Table 2 is used. Among them, the MCS table obtained based on Table 2 can be understood as the MCS table obtained by adding the first MCS in Table 2, that is, the first type of MCS table includes the MCS table obtained based on Table 2.

[0207] Further, the sending device indicates the index of the first MCS in the first MCS table through a MCS indication field (an example of the first indication information) in a downlink control information (DCI). The MCS indication field occupies more than 5 bits, for example, 6 bits, i.e., the maximum value of the index that can be indicated by the MCS indication field is 63 (the index is numbered from 0).

[0208] Based on the above scheme, in the signal transmission process, the sending device and the receiving device can select a MCS suitable for the co-sensing signal from the first type of MCS table to perform modulation and coding processing on the signal, thereby improving the performance of communication and sensing.

[0209] For the second possible implementation, the second type of MCS table can be understood as one or more newly designed MCS tables, wherein each newly designed MCS table can be composed of multiple first MCSs. That is, in addition to the MCS tables in the existing standard, one or more MCS tables for modulation and coding processing of co-sensing signals can also be designed.

[0210] Exemplarily, the modulation order corresponding to a MCS in the second type of MCS table can be 2, 3, 4, 5, or 6. Each MCS in the second type of MCS table can correspond to one or more modulation modes.

[0211] 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 mode corresponding to MCS#3 can be QPSK. That is, QPSK can be suitable for modulation and coding processing of co-sensing signals.

[0212] 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 corresponds to 8-P-QAM. Wherein, 8-P-QAM is described with reference to the first implementation.

[0213] 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 corresponds to 16-P-QAM. Wherein, 16-P-QAM is described with reference to the first implementation.

[0214] When the modulation order corresponding to the MCS #3 is 5, the MCS #3 can correspond to one or more of 32-QAM, at least one 32-P-QAM, APSK and DVB, or the MCS #3 corresponds to any one of at least one 32-P-QAM. Wherein, the 32-P-QAM refers to the description in the first implementation.

[0215] When the modulation order corresponding to the MCS #3 is 6, the modulation mode corresponding to the MCS #3 is 64-QAM, that is, 64-QAM can be applied to the modulation and coding processing of the common sense signal.

[0216] Similarly, the code rate (i.e. target code rate x 1024) and spectral efficiency corresponding to the MCS in the second type of MCS table are not limited. For details, refer to the description in the first implementation.

[0217] As shown in Table 5 is an example of the second type of MCS table.

[0218] Table 5

[0219] In Table 5, the MCS corresponding to the index 0-28 can be used for the modulation and coding processing of the common sense signal. "-" indicates that the code rate or spectral efficiency corresponding to the MCS is not shown, and the value of the code rate corresponding to the MCS can be obtained in combination with the value range of the code rate and the simulation experiment.

[0220] It can be understood that Table 5 is only one form of the second type of MCS table, and the second type of MCS table can also be 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 is not listed one by one.

[0221] Optionally, the sending end device indicates the first MCS table to the receiving end device, and indicates the index corresponding to the first MCS in the first MCS table through the first indication information.

[0222] In one example, the sending end device indicates the first MCS table through the indication information #1 (an example of the third indication information), and the indication information #1 indicates that the first MCS table is one of the second type of MCS table and the third type of MCS table. Wherein, the third type of MCS table refers to the MCS table in the existing standard (for example, Table 1, Table 2 and Table 3).

[0223] For example, the transmitter device indicates the first MCS table through a high layer parameter (e.g., MCS-table, an example of indication information #1). The MCS-table can be carried in PDSCH configuration (PDSCH config) and / or SRS configuration (e.g., SPS config). When the MCS-table is configured as ‘ISACComm’ or ‘ISACSens’, it indicates to use the MCS table as shown in Table 5 (an example of the first MCS table); the MCS-table can also be configured as ‘qam256’ or ‘qam64LowSE’, or not configured, in which case it can indicate to use the MCS table in the existing standard (e.g., Table 1, Table 2 or Table 3).

[0224] In another example, the transmitter 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.

[0225] For example, the transmitter device indicates that the first MCS table belongs to the second type of MCS table through 1 bit (an example of the first field) in the DCI, such as indicating that the first MCS table belongs to the second type of MCS table through the value of the bit being one of “0” and “1”. Alternatively, when the value of the bit is the other of “0” and “1”, it indicates that the used MCS table belongs to the third type of MCS table, which is referred to the first example.

[0226] In this example, for indication information #3, the configuration of the existing high layer parameter MCS-table can be reused, for example, when the high layer parameter MCS-table is configured as ‘qam256’ or ‘qam64LowSE’, it can indicate to use the MCS table as shown in Table 5 (an example of the first MCS table).

[0227] That is, the transmitter device can indicate through 1 bit in the DCI whether the used MCS table belongs to the second type of MCS table or the third type of MCS table. Further, the transmitter device indicates that the used MCS table belongs to one of the second type of MCS tables or one of the third type of MCS tables through the high layer parameter MCS-table.

[0228] It should be understood that the selection of the 1-bit in the DCI described above, and the specific indication manner of the indication information #2 are not limited, 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 MCS table belongs to the second type of MCS table or the third type of MCS table; or, one bit in the existing DCI can be multiplexed to implicitly indicate that the first MCS table belongs to the second type of MCS table or the third type of MCS table.

[0229] In another example, the sending end device can also indicate whether the used MCS table belongs to the second type of MCS table or the third type of MCS table through a resource configuration manner corresponding to the to-be-transmitted signal.

[0230] For example, if the resource configuration manner corresponding to the to-be-transmitted signal is resource configuration based on resource element (RE) granularity, or in other words, the resources configured for the to-be-transmitted signal are indicated in the granularity of RE, then the used MCS table (that is, the first MCS table) belongs to the second type of MCS table.

[0231] If the resource configuration manner corresponding to the to-be-transmitted signal is resource configuration based on resource block (RB) granularity, or in other words, the resources configured for the to-be-transmitted signal are indicated in the granularity of RB, then the used MCS table (that is, the first MCS table) belongs to the third type of MCS table.

[0232] The present application does not limit the specific resource configuration manner. For example, the allocated RE or RB can be indicated by a bit map; for another example, the allocated RE (RB) can be indicated by indicating the starting RE (RB) and the number of consecutive REs (RBs).

[0233] Further, the sending end device indicates the index of the first MCS in the first MCS table through the MCS indication field (an example of the first indication information) in the DCI. In this implementation manner, the number of bits occupied by the MCS indication field refers to the existing related description. That is, compared with 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 need to change the MCS indication field in the existing DCI, and can better compatible with the existing MCS indication manner.

[0234] Based on the above scheme, in the signal transmission process, the sending device and the receiving device can select an MCS suitable for the common signal from the second MCS table to modulate and encode the signal, thereby improving the performance of communication and perception.

[0235] Optionally, in the above two implementation manners, when the modulation mode corresponding to the first MCS is multiple, the sending device can further indicate one of the multiple modulation modes.

[0236] For example, the receiving device is configured with a plurality of constellation diagrams corresponding to modulation modes, and the sending device can indicate one of the plurality of constellation diagrams through a field (an example of the second field) in the DCI. Similarly, the selection of the second field and the specific indication manner of the second field are not limited.

[0237] Optionally, the constellation diagram corresponding to the modulation mode(s) corresponding to the first MCS can be configured by the sending device through configuration information (an example of the second configuration information). For example, the configuration information is carried in radio resource control (RRC) signaling, medium access control (MAC) signaling or other downlink signaling.

[0238] In S620, the sending device transmits a data signal to the receiving device based on the first MCS.

[0239] For example, the sending device can modulate and encode the data signal according to the modulation mode corresponding to the first MCS and the code rate, and send the modulated and encoded signal to the receiving device. Correspondingly, after receiving the modulated and encoded signal, the receiving device can demodulate and decode the received signal according to the first MCS.

[0240] Based on the above scheme, in the signal transmission process, the sending device and the receiving device can select an MCS suitable for the common signal to modulate and encode the signal, thereby improving the performance of communication and perception.

[0241] It can be understood that in the above embodiments, “transmission” is mentioned, and in the case where no special description is made, transmission includes receiving and / or sending. For example, transmitting a signal can include receiving a signal and / or sending a signal.
