Description

Wireless communication method and device Technical Field

[0001] The embodiments of the present invention relate to the field of wireless communication technology, and particularly to a wireless communication method and apparatus. Background Art

[0002] As wireless communication applications become increasingly diverse, a wealth of new data is emerging during wireless communications. For example, smart factories generate a wide range of data types, including video, sensor, perception, artificial intelligence, and control data. These data types are characterized by large volumes, redundancy, correlation, and a tolerance for lossy compression and transmission. Adapting these data characteristics to achieve efficient data transmission and improve wireless communication efficiency has become a pressing issue.

[0003] Summary of the Invention

[0004] The present application provides a wireless communication method and apparatus to adapt to data characteristics for efficient data transmission and improve wireless communication efficiency.

[0005] In a first aspect, the present application relates to a wireless communication method, applied to a first communication subject, comprising: sending configuration information of transmission control information, sending target data in the case of downlink transmission, or receiving target data in the case of uplink transmission.

[0006] The configuration information of the transmission control information is used to indicate the configuration of the transmission control information. The transmission control information includes an indication parameter of a target modulation and coding strategy combination. The indication parameter of the target modulation and coding strategy combination indicates multiple modulation and coding strategies. Each of the multiple modulation and coding strategies is used to modulate and encode the data to be transmitted to obtain the target data.

[0007] Transmission control information can be understood as information used to control data transmission. For example, downlink control information, radio resource control signaling, etc. can be understood as a type of transmission control information.

[0008] The modulation and coding strategy defines the effective number of bits that can be carried by a resource unit. The modulation and coding strategy is related to both the modulation scheme and the bit rate; together, they determine the number of bits that can be transmitted simultaneously per unit time. The modulation and coding strategy also combines modulation and coding into multiple levels. The higher the level, the faster the data transmission rate. The modulated data signal can then be transmitted.

[0009] Modulation is used to map coded data onto modulation symbols, allowing the modulated signal to be transmitted. A modulation symbol can be understood as the basic unit used to carry data within a specific modulation scheme. A modulation symbol represents a specific signal state, containing information that can be transmitted and received through the modulation and demodulation processes. It is typically represented by a set of discrete signal states, or symbol points. Each modulation symbol represents a certain number of bits, depending on the modulation scheme and modulation order used.

[0010] The code rate can be understood as the ratio between useful bits and total transmitted bits. The code rate is used to measure the redundancy added by the physical layer. The redundant bits are used for forward error correction. The code rate value is negatively correlated with the added redundant bits.

[0011] According to the wireless communication method of the present application, the configuration information of the transmission control information is used to indicate the configuration of the transmission control information. The transmission control information can be used to control data transmission so that the data is transmitted in the manner indicated by the transmission control information to perform wireless communication. Since the transmission control information of the present application includes an indication parameter of a target modulation and coding strategy combination, the indication parameter of the target modulation and coding strategy combination indicates multiple modulation and coding strategies. Therefore, the transmission control information can be used to indicate multiple modulation and coding strategies. Each of the multiple modulation and coding strategies can modulate and encode a certain part of the data to be transmitted, so that the transmission data can be modulated and encoded in a variety of different ways using multiple modulation and coding strategies. This can adapt to differentiated data, achieve differentiated data transmission and unequal protection, and improve wireless communication efficiency.

[0012] For example, for the more important data to be transmitted, a lower-order modulation and coding strategy can be mapped (one of the multiple modulation and coding strategy combinations indicated by the target modulation and coding strategy combination is the lower-order modulation and coding strategy) for modulation and coding. Since the low-order modulation and coding strategy has a higher error tolerance for the transmitted data, the more important data to be transmitted can be guaranteed to have a lower bit error rate even if it is transmitted through a channel with poor quality, and the wireless communication efficiency is higher.

[0013] In one possible example, the target modulation and coding strategy combination is determined based on at least one candidate modulation and coding strategy combination, at least one candidate modulation and coding strategy combination is mapped to a first index, and an indication parameter of the target modulation and coding strategy combination indicates the target modulation and coding strategy combination by indicating the first index.

[0014] A candidate modulation and coding strategy combination can be understood as a candidate modulation and coding strategy combination. The modulation and coding strategy combination includes multiple modulation and coding strategies, each of which is used to modulate and encode data to be transmitted to obtain target data. A target modulation and coding strategy combination can be understood as being selected from at least one candidate modulation and coding strategy combination.

[0015] According to the wireless communication method of the present application, a target modulation and coding strategy combination can be indirectly indicated by indicating a first index. Compared to directly indicating multiple modulation and coding strategy combinations represented by the target modulation and coding strategy combination, this indirect indication of the target modulation and coding strategy combination has lower communication overhead and higher wireless communication efficiency. In particular, when the number of modulation and coding strategies represented by the target modulation and coding strategy combination is relatively large, the communication overhead is reduced.

[0016] In one possible example, the target mapping table represents at least one candidate modulation and coding strategy combination, the target mapping table is determined based on at least one candidate mapping table, the transmission control information also includes an indication parameter of the target mapping table, at least one candidate mapping table is mapped to a second index, and the indication parameter of the target mapping table indicates the target mapping table by indicating the second index.

[0017] The target mapping table can be understood as being selected from at least one candidate mapping table.

[0018] According to the wireless communication method of the present application, on the one hand, by indicating the second index, the target mapping table can be indirectly indicated. Compared with directly indicating the target mapping table, indirectly indicating the target mapping table has lower communication overhead and higher wireless communication efficiency. On the other hand, determining the target modulation and coding strategy combination from at least one candidate modulation and coding strategy combination represented by the target mapping table and determining the target mapping table from at least one candidate mapping table allows the target modulation and coding strategy combination to have a larger selection range, adapt to a wider range of applications, and is more flexible.

[0019] In a possible example, the transmission control information is indicated by downlink control information, the downlink control information is loaded through a physical shared channel, and the configuration of the downlink control information includes the format of the downlink control information.

[0020] Downlink control information is a type of control information used for resource allocation and scheduling.

[0021] The physical shared channel may be, for example, a physical downlink shared channel or a physical uplink shared channel.

[0022] The downlink control information is classified into different formats according to the type of indication information, and each format corresponds to a size or parsing method of the downlink control information.

[0023] According to the wireless communication method of the present application, when the target mapping table has been determined, the target modulation and coding strategy combination can be indicated by downlink control information (specifically, the target modulation and coding strategy combination is indicated by the first index). When the target mapping table is selected from multiple candidate mapping tables, both the target modulation and coding strategy combination and the target mapping table can be indicated by downlink control information (specifically, the target modulation and coding strategy combination is indicated by the first index and the target mapping table is indicated by the second index). Therefore, according to the wireless communication method of the present application, transmission control information can be directly indicated at the physical layer through downlink control information, for example, the real-time performance of adjusting the target mapping table and / or the target modulation and coding strategy combination is better, and the wireless communication efficiency is higher.

[0024] In a possible example, the wireless communication method further includes: sending configuration information of the candidate mapping table.

[0025] The configuration information of the candidate mapping table is used to indicate the configuration of the candidate mapping table.

[0026] According to the wireless communication method of the present application, the configuration of the candidate mapping table can be indicated by sending the configuration information of the candidate mapping table, thereby allowing the candidate mapping table to be flexibly configured, for example, the specifications of the candidate mapping table can be adjusted, the candidate mapping table can be updated, etc. to adapt to a wide range of flexible application scenarios, with higher wireless communication efficiency.

[0027] In a possible example, the transmission control information and / or the configuration information of the candidate mapping table is indicated through radio resource control signaling.

[0028] According to the wireless communication method of the present application, transmission control information and / or configuration information of the candidate mapping table can be indicated in the form of radio resource control signaling. When the transmission control information and / or configuration information of the candidate mapping table is indicated in the form of radio resource control signaling, the transmission control information and / or configuration information of the candidate mapping table can be written into the communication protocol, and the transmission control information and / or configuration information of the candidate mapping table can be represented by adding parameters to the communication protocol.

[0029] It should also be noted that wireless resource control signaling is used for signaling interaction in the wireless resource control layer of the communication system. Since the wireless resource control layer is located at the top layer, signaling interaction through wireless resource control signaling to achieve transmission control is more complex and has longer delays. It is suitable for scenarios with lower real-time performance. For example, when the transmission control information and / or the configuration information of the candidate mapping table is not adjusted for a long period of time, the transmission control information and / or the configuration information of the candidate mapping table can be indicated by wireless resource control signaling.

[0030] In a possible example, the wireless communication method further includes: receiving data attribute indication information of the data to be transmitted.

[0031] The data attribute indication information is used to determine a target mapping table and / or a target modulation and coding strategy combination.

[0032] The data attributes of the data to be transmitted can characterize the characteristics of the data to be transmitted, and the characteristics of the data to be transmitted represented by the data attributes of the data to be transmitted can be matched and mapped with the target mapping table and / or the target modulation and coding strategy combination, so that the target mapping table and / or the target modulation and coding strategy combination can be accurately and efficiently determined according to the data attributes of the data to be transmitted, so as to utilize a variety of different modulation and coding strategies to modulate and encode the data to be transmitted with different characteristics, thereby realizing differentiated transmission and unequal protection.

[0033] For example, the data attributes of the data to be transmitted may include data type, error tolerance requirements, etc. Data types may include, for example, text data, audio data, image data, video data, etc. Error tolerance requirements may include, for example, error tolerance transmission indication information indicating lossy or lossless transmission, and the maximum transmission bit error rate that can be tolerated by the data to be transmitted.

Each of the multiple modulation and coding strategies is used to modulate and encode the data to be transmitted to obtain the target data.

[0036] In a possible example, the wireless communication method further includes: sending data attribute indication information of the data to be transmitted.

[0037] The data attribute indication information is used to determine the target mapping table and / or target modulation and coding strategy combination. The target modulation and coding strategy combination is determined based on at least one candidate modulation and coding strategy combination. The target mapping table represents at least one candidate modulation and coding strategy combination. The transmission control information also includes indication parameters of the target mapping table.

[0042] The second module is configured to send target data in the case of downlink transmission, or receive target data in the case of uplink transmission.

[0069] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0070] The term "and / or" in this article is merely a description of the association relationship between associated objects, indicating that three relationships may exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone.

[0071] In the description and claims of the embodiments of this application, the terms "first" and "second" are used to distinguish different objects, rather than to describe a specific order of objects. For example, the terms "first target object" and "second target object" are used to distinguish different objects, rather than to describe a specific order of objects.

[0072] In the embodiments of this application, words such as "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of this application should not be interpreted as being preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0073] It should be understood that in this application, "at least one (item)" means one or more, and "plurality" means two or more. "And / or" is used to describe the association relationship of associated objects, indicating that three relationships may exist. For example, "A and / or B" can mean: only A exists, only B exists, and A and B exist at the same time, where A and B can be singular or plural. The character " / " generally indicates that the previous and next associated objects are in an "or" relationship. "At least one of the following items" or similar expressions refers to any combination of these items, including any combination of single items or plural items. For example, at least one of a, b or c can mean: a, b, c, "a and b", "a and c", "b and c", or "a and b and c", where a, b, c can be single or multiple.

[0074] The following describes in detail the background of the wireless communication method according to the embodiment of the present disclosure.

[0075] As wireless communication application scenarios become increasingly diverse, a lot of data for new scenarios will appear in the wireless communication process.

[0076] For example, smart factory scenarios generate various types of data, including video data, sensor data, perception data, artificial intelligence data, and control data. Perception data includes, for example, 2D imaging data, 3D imaging data, environmental reconstruction data, point cloud data, positioning data, and tracking data. Artificial intelligence data includes, for example, model parameter data for machine learning models, gradient update data, and feature information extracted by neural networks.

[0077] The above data has the characteristics of large data volume, redundancy or correlation, and can accept certain lossy compression / transmission. For example, imaging data and radar detection data are very sparse; positioning and tracking data, environmental imaging / reconstruction data, artificial intelligence data, etc. obtained in continuous time have strong temporal correlation.

[0078] In some implementations, data with the above characteristics is transmitted without any difference, and the efficiency of wireless communication needs to be improved. Therefore, how to adapt to the above characteristics of data to perform efficient data transmission and improve wireless communication efficiency has become an urgent problem to be solved.

[0079] Wireless communication technology primarily relies on the transmission of electromagnetic waves to transfer information. When a transmitter generates electromagnetic waves, they propagate through the air at a certain speed. The receiver receives these waves through an antenna and converts them into electrical signals, which are then demodulated and processed to recover the original information.

[0080] Wireless communication technology has continuously evolved from the first generation of mobile communication technology (1G) to the currently more mature fifth generation of mobile communication technology (5G) and has been iterating. 5G technology not only meets the needs of individual users for high-speed mobile Internet and multimedia applications, but also provides support for the development of industrial automation, intelligent transportation, smart cities, healthcare and other fields.

[0081] The wireless communication methods and apparatuses of the disclosed embodiments use a cellular network as an example (of course, other types of network communication systems, such as Wi-Fi, may also be included). A cellular network consists of multiple small areas (i.e., cells), each of which is covered by a base station. The base station provides wireless communication services to user devices within the cell's communication range. These base stations are connected to the Internet or other network centers via wired or wireless means, forming an integrated wireless communication system.

[0082] In wireless communication systems, a communication subject can be understood as the communication device that supports wireless communication. Communication devices can be divided into devices that provide network services and devices that use network services. Communication devices that provide network services are typically those devices that make up the network and can be simply referred to as network equipment or network elements. Devices that use network services are typically located at the edge of the network and can be simply referred to as terminals (terminals are also called user equipment, or UE). Terminals can establish connections with network devices and use the services provided by them.

[0083] Taking a mobile communication system as an example, the mobile communication network can be further divided into the Radio Access Network (RAN) and the Core Network (CN). Accordingly, network equipment can be further divided into Radio Access Network equipment and Core Network equipment. Radio Access Network equipment is primarily responsible for wireless-related functions. Core Network equipment is primarily responsible for the overall functionality of the network and is generally divided into User Plane (UP) equipment and Control Plane (CN) equipment. The User Plane primarily involves the transmission of user data. This user data is generally considered to be the payload of communication services, such as text, voice, video, and other data content that meets user needs. In the embodiments of the present disclosure, user plane data or user data, for example, includes various types of data such as the aforementioned video data, sensor data, perception data, artificial intelligence data, control data, etc., and can be understood as service data. The Control Plane primarily involves the transmission of control signaling. This control signaling is an auxiliary overhead for service data transmission, but is crucial for ensuring the efficiency and reliability of service data transmission.

[0084] FIG1 schematically shows a schematic diagram of a system architecture of a wireless communication method and apparatus according to an embodiment of the present disclosure.

[0085] It should be noted that Figure 1 is only an example of a system architecture to which the wireless communication method and device of the embodiments of the present disclosure can be applied, to help those skilled in the art understand the technical content of the present disclosure, but it does not mean that the embodiments of the present disclosure cannot be applied to other devices, systems, environments or scenarios.

[0086] As shown in FIG1 , the system architecture of the wireless communication method and apparatus according to an embodiment of the present disclosure includes: a first communication subject 101 and second communication subjects 102 , 103 , and 104 .

[0087] The first communication subject 101 and the second communication subjects 102, 103, 104 are both parties in wireless communication. The following description will take the first communication subject 101 as a base station (BS) and the second communication subjects 102, 103, 104 as user equipment as an example.

[0088] Logically, the base station can be understood as a scheduling entity, and the user equipment as a subordinate entity. The scheduling entity is responsible for scheduling and controlling service data transmission, while the subordinate entity executes service data transmission based on the scheduling entity's control. For example, the base station sends an uplink scheduling grant to the user equipment, and the user equipment sends uplink data transmission to the base station based on the uplink scheduling grant.

[0089] In terms of physical form, base stations may include but are not limited to macro base stations, micro base stations, transmission reception points (TRPs), baseband units (BBUs), and remote radio units (RRUs). Micro base stations are sometimes also referred to as small cells. User devices may include but are not limited to mobile phones, tablet computers, laptop computers, wearable devices (smart watches, smart bracelets, smart helmets, smart glasses, etc.), and other communication devices with wireless access capabilities, such as various IoT devices, including smart home devices (smart meters, smart appliances, etc.) and smart vehicles.

[0090] Generally, according to the data transmission direction on the communication link, the communication link from the base station to the user equipment is called a downlink (DL); conversely, the communication link from the user equipment to the base station is called an uplink (UL).

[0091] It should be understood that the one base station and one user equipment shown in FIG1 are merely examples, and any number of base stations and user equipment may be set up as required. In some other embodiments of the system architecture, other network devices may also be included.

[0092] The first communication subject 101 can, for example, send configuration information for transmission control information and send target data in the case of downlink transmission, or receive target data in the case of uplink transmission. Accordingly, the wireless communication device provided in the embodiments of the present disclosure can generally be provided in the first communication subject 101. The wireless communication method provided in the embodiments of the present disclosure can also be performed by other communication subjects different from the first communication subject 101 and capable of wirelessly communicating with the second communication subjects 102, 103, and 104.

[0093] The second communication entities 102, 103, and 104 can, for example, receive configuration information for transmission control information. They can receive target data in the case of downlink transmission, or send target data in the case of uplink transmission. Accordingly, the wireless communication device provided in the embodiments of the present disclosure can generally be provided in the second communication entities 102, 103, and 104. The wireless communication method provided in the embodiments of the present disclosure can also be performed by other communication entities that are different from the second communication entities 102, 103, and 104 and that are capable of wirelessly communicating with the first communication entity 101.

[0094] The configuration information of the transmission control information is used to indicate the configuration of the transmission control information. The transmission control information includes an indication parameter of a target modulation and coding strategy combination. The indication parameter of the target modulation and coding strategy combination indicates multiple modulation and coding strategies. Each of the multiple modulation and coding strategies is used to modulate and encode the data to be transmitted to obtain the target data.

[0095] It should be understood that the system architecture provided by the embodiments of the present disclosure is not limited to the type of wireless communication system.

[0096] An embodiment of the present disclosure provides a wireless communication method. The wireless communication method of the exemplary embodiment of the present disclosure is described below with reference to FIG. 2A to FIG. 4 in combination with the system architecture of FIG. 1 .

[0097] FIG2A schematically shows a flow chart of a wireless communication method 200 according to an embodiment of the present disclosure, and FIG2B schematically shows a schematic diagram of a wireless communication method according to an embodiment of the present disclosure.

[0098] The wireless communication method may be executed by, for example, the first communication subject shown in Figure 1. The first communication subject may be, for example, a base station.

[0099] As shown in FIG. 2A , the wireless communication method 200 according to an embodiment of the present disclosure includes operations S210 to S220 .

[0100] In operation S210, configuration information of transmission control information is transmitted.

[0101] The configuration information of the transmission control information is used to indicate the configuration of the transmission control information. The transmission control information can be understood as information used to control data transmission, for example, downlink control information, radio resource control signaling, etc. can be understood as a type of transmission control information.

[0102] The transmission control information includes parameters indicating a target modulation and coding scheme combination. The parameters indicating the target modulation and coding scheme combination indicate multiple modulation and coding schemes (MCSs). Each of the multiple modulation and coding schemes is used to modulate and encode the data to be transmitted to obtain the target data.

[0103] The modulation and coding strategy (MCS) defines the effective number of bits that a resource element (RE) can carry. The MCS is related to both the modulation scheme and the code rate, which together determine the number of bits that can be transmitted simultaneously per unit time. MCS also combines modulation and coding into multiple levels, with higher levels resulting in faster data transmission rates. The modulated data signal can then be transmitted.

[0104] Modulation is used to map coded data onto modulation symbols, allowing the modulated signal to be transmitted. A modulation symbol can be understood as the basic unit used to carry data within a specific modulation scheme. A modulation symbol represents a specific signal state, containing information that can be transmitted and received through the modulation and demodulation processes. It is typically represented by a set of discrete signal states, or symbol points. Each modulation symbol represents a certain number of bits, depending on the modulation scheme and modulation order used.

[0105] Typical modulation schemes include BPSK (Binary Phase Shift Keying), QPSK (Quadrature Phase Shift Keying), 16QAM (16 Quadrature Amplitude Modulation, a quadrature amplitude modulation with 16 modulation symbols), 64QAM (64 Quadrature Amplitude Modulation, a quadrature amplitude modulation with 64 modulation symbols), and 256QAM (256 Quadrature Amplitude Modulation, a quadrature amplitude modulation with 256 modulation symbols). Correspondingly, the modulation orders of these modulation schemes are 1, 2, 4, 6, and 8, respectively, and the number of bits transmitted simultaneously for each modulation symbol is 1, 2, 4, 6, and 8, respectively. Furthermore, when encoding the original data, redundant bits are introduced for error correction. Only a portion of the data is actually useful, and the redundant bits are discarded during decoding.

[0106] The code rate can be understood as the ratio between useful bits and total transmitted bits. The code rate is used to measure the redundancy added by the physical layer. The redundant bits are used for forward error correction. The code rate value is negatively correlated with the added redundant bits.

[0107] In operation S220, target data is transmitted in case of downlink transmission, or received in case of uplink transmission.

[0108] As shown in Figure 2B, the data Da to be transmitted, for example, includes data Da_1 to data Da_4. According to the wireless communication method of the embodiment of the present disclosure, for example, the four modulation and coding strategies MCS_1 to MCS_4 indicated by the target modulation and coding strategy combination can be used to modulate and encode the data Da_1 to data Da_4 one by one to obtain the target data Da_t. The target data Da_t includes transmission blocks TB_1 to TB_4 modulated and encoded by the modulation and coding strategies MCS_1 to MCS_4, respectively.

[0109] According to the wireless communication method of the embodiment of the present disclosure, the configuration information of the transmission control information is used to indicate the configuration of the transmission control information. The transmission control information can be used to control data transmission so that the data is transmitted in the manner indicated by the transmission control information to perform wireless communication. Since the transmission control information of the embodiment of the present disclosure includes an indication parameter of a target modulation and coding strategy combination, and the indication parameter of the target modulation and coding strategy combination indicates multiple modulation and coding strategies, the transmission control information can be used to indicate multiple modulation and coding strategies. Each of the multiple modulation and coding strategies can modulate and encode a certain part of the data to be transmitted, so that the transmission data can be modulated and encoded in a variety of different ways using multiple modulation and coding strategies. This can adapt to differentiated data, realize differentiated data transmission and unequal error protection (UEP), and improve wireless communication efficiency.

[0110] For example, for the more important data to be transmitted, a lower-order modulation and coding strategy can be mapped (one of the multiple modulation and coding strategy combinations indicated by the target modulation and coding strategy combination is the lower-order modulation and coding strategy) for modulation and coding. Since the low-order modulation and coding strategy has a higher error tolerance for the transmitted data, the more important data to be transmitted can be guaranteed to have a lower bit error rate even if it is transmitted through a channel with poor quality, and the wireless communication efficiency is higher.

[0111] In conjunction with the system architecture of the wireless communication method shown in Figure 1, taking wireless communication between a first communication subject and a second communication subject, where the data transmission direction of the first communication subject sending data to the second communication subject is downlink transmission, and the data transmission direction of the second communication subject sending data to the first communication subject is uplink transmission as an example, the first communication subject sends configuration information of transmission control information to the second communication subject. The second communication subject can receive the configuration information of the transmission control information sent by the first communication subject and process the data to be transmitted according to the configuration information of the transmission control information, obtain the target data, and send the target data to the first communication subject to achieve uplink transmission. In addition, the first communication subject can process the data to be transmitted according to the configuration information of the transmission control information, obtain the target data, and send the target data to the second communication subject to achieve downlink transmission.

[0112] According to another embodiment of the wireless communication method of the present disclosure, a target modulation and coding strategy combination is determined based on at least one candidate modulation and coding strategy combination. The at least one candidate modulation and coding strategy combination is mapped to a first index. An indication parameter of the target modulation and coding strategy combination indicates the target modulation and coding strategy combination by indicating the first index.

[0113] A candidate modulation and coding strategy combination can be understood as a candidate modulation and coding strategy combination. The modulation and coding strategy combination includes multiple modulation and coding strategies, each of which is used to modulate and encode data to be transmitted to obtain target data. A target modulation and coding strategy combination can be understood as being selected from at least one candidate modulation and coding strategy combination.

[0114] According to the wireless communication method of the embodiment of the present disclosure, a target modulation and coding strategy combination can be indirectly indicated by indicating a first index. Compared to directly indicating multiple modulation and coding strategy combinations represented by the target modulation and coding strategy combination, this indirect indication of the target modulation and coding strategy combination has lower communication overhead and higher wireless communication efficiency. In particular, when the number of modulation and coding strategies represented by the target modulation and coding strategy combination is relatively large, the communication overhead is reduced.

[0115] According to a wireless communication method of another embodiment of the present disclosure, the target mapping table represents an indication of a candidate modulation and coding strategy combination, the target mapping table is determined based on at least one candidate mapping table, the transmission control information also includes an indication parameter of the target mapping table, at least one candidate mapping table is mapped to a second index, and the indication parameter of the target mapping table indicates the target mapping table by indicating the second index.

[0116] The target mapping table can be understood as being selected from at least one candidate mapping table.

[0117] According to the wireless communication method of the embodiment of the present disclosure, on the one hand, the target mapping table can be indirectly indicated by indicating the second index. Compared with directly indicating the target mapping table, indirectly indicating the target mapping table has lower communication overhead and higher wireless communication efficiency. On the other hand, determining the target modulation and coding strategy combination from at least one candidate modulation and coding strategy combination represented by the target mapping table and determining the target mapping table from at least one candidate mapping table allows the target modulation and coding strategy combination to have a larger selection range, adapt to a wider range of applications, and is more flexible.

[0118] Table 1 schematically illustrates a target mapping table for a wireless communication method according to an embodiment. In this example, the target mapping table represents multiple candidate modulation and coding strategy combinations. Table 2 schematically illustrates the meaning of the numbers under the modulation and coding strategy MCS field, i.e., the index representing the modulation order and coding rate.

[0119] In the example of Table 1, the target modulation and coding strategy combination represents a combination of a total of 4 modulation and coding strategies from MCS1 to MCS4. Each of the 4 modulation and coding strategies from MCS1 to MCS4 corresponds to a different modulation order and coding rate. In the example of Table 1, the modulation order and coding rate represented by the numbers under the modulation and coding strategy MCS field are shown in Table 2. For example, the number "2" under the MCS1 field corresponding to the first index 0 indicates that the modulation order is QPSK and the coding rate is 308 / 1024. In the example of Table 1, the "first index" field represents the index of the candidate modulation and coding strategy combination, and each candidate modulation and coding strategy combination can be mapped through the first index. Figure 1 exemplifies a specific example of a total of 64 candidate modulation and coding strategy combinations with first indices numbered "0" to "63".

[0120] Table 1

[0121] Table 2

[0122] Exemplarily, for example, 8 bits may be used to represent each of the 64 candidate modulation and coding strategy combinations shown in Table 1.

[0123] Table 3 schematically illustrates multiple candidate mapping tables of a wireless communication method according to an embodiment.

[0124] Table 3

[0125] Table 3 schematically shows an example of a total of eight candidate mapping tables, namely, candidate mapping table S0 to candidate mapping table S7.

[0126] For example, in the example of 8 candidate mapping tables shown in Table 3, for example, 3 bits can be used to represent a target mapping table selected from the 8 candidate mapping tables. For example, a 3Mbit or 8-bit bitmap can also be used to represent M mapping tables selected from the 8 candidate mapping tables (M is a positive integer less than or equal to 8), and the target mapping table can be selected from the M mapping tables.

[0127] It should also be noted that Table 1 is only an example of a target mapping table, and the wireless communication method of the present disclosure does not limit the specifications of the target mapping table. In the case of multiple candidate mapping tables, the wireless communication method of the present disclosure does not limit the specifications of any candidate mapping table.

[0128] Exemplarily, according to a wireless communication method of yet another embodiment of the present disclosure, transmission control information is indicated by downlink control information.

[0129] The downlink control information is loaded through the physical shared channel, and the configuration of the downlink control information includes the format of the downlink control information.

[0130] Downlink Control Information (DCI) is a type of control information used for resource allocation and scheduling.

[0131] The physical shared channel may be, for example, a physical downlink shared channel (PDSCH) or a physical uplink shared channel (PUSCH).

[0132] DCI is divided into different formats according to the type of indication information, and each format corresponds to a DCI size or parsing method. The DCI formats defined in the 3GPP standard include, for example, Format0_0, Format0_1, Format1_0, Format1_1, Format2_0, Format2_1, Format2_2, and Format2_3.

[0133] According to the wireless communication method of the embodiment of the present disclosure, when the target mapping table has been determined, the target modulation and coding strategy combination can be indicated by downlink control information (specifically, the target modulation and coding strategy combination is indicated by the first index). When the target mapping table is selected from multiple candidate mapping tables, both the target modulation and coding strategy combination and the target mapping table can be indicated by downlink control information (specifically, the target modulation and coding strategy combination is indicated by the first index and the target mapping table is indicated by the second index). Therefore, according to the wireless communication method of the embodiment of the present disclosure, transmission control information can be directly indicated at the physical layer through downlink control information, for example, the real-time performance of adjusting the target mapping table and / or the target modulation and coding strategy combination is better, and the wireless communication efficiency is higher.

[0134] Exemplarily, according to the wireless communication method of an embodiment of the present disclosure, FIG3 and FIG4 schematically illustrate examples of two formats of downlink control information respectively.

[0135] In the example of FIG3 , the format of the DCI may include an indication parameter representing the target modulation and coding strategy combination.

[0136] In the example of FIG. 4 , the format of the DCI may include an indication parameter representing a target modulation and coding strategy combination and an indication parameter of a target mapping table.

[0137] In the examples of FIG. 3 and FIG. 4 , the format of the downlink control information may further include an indication parameter representing a redundancy version (RV) and new data indication information (NDI).

[0138] The number of redundancy version indication parameters and the number of modulation and coding strategies included in the downlink control information are both the same as the number of multiple modulation and coding strategies indicated by the target modulation and coding strategy combination.

[0139] In the examples of Figures 3 and 4, taking the target modulation and coding strategy combination indicating N modulation and coding strategy combinations as an example (N is an integer greater than or equal to 2), the format of the downlink control information is schematically shown to include indication parameters of a total of N redundant versions from RV_1 to RV_N and a specific example of a total of N new data indication information from NDI_1 to NDI_N.

[0140] For example, in the examples of FIG. 3 and FIG. 4 , for example, simultaneous indication of N TBs (Transport Blocks) may be supported, and each TB includes a set of NDI and RV.

[0141] Exemplarily, the format of the downlink control information, except for the indication parameters representing the target modulation and coding strategy combination, the indication parameters of the target mapping table, the indication parameters of the redundant version, and the new data indication information, the rest of the format can be the same as one of Format0_0, Format0_1, Format1_0, Format1_1, Format2_0, Format2_1, Format2_2 and Format2_3, and will not be repeated here.

[0142] According to the wireless communication method of the embodiment of the present disclosure, by configuring the format of the downlink control information, the format of the downlink control information can be used to represent the indication parameters of the target modulation and coding strategy combination, or the format of the downlink control information can be used to represent both the target modulation and coding strategy combination and the target mapping table, thereby realizing the use of the downlink control information to indicate the target modulation and coding strategy combination, or realizing the use of the downlink control information to indicate both the target modulation and coding strategy combination and the target mapping table. The base station or user equipment can modulate and encode the data to be transmitted according to the multiple modulation and coding strategies indicated by (the target mapping table and) the target modulation and coding strategy combination indicated by the downlink control information to obtain the target data, thereby adapting to differentiated data and improving wireless communication efficiency.

[0143] According to yet another embodiment of the present disclosure, the wireless communication method may further include, for example: sending configuration information of the candidate mapping table.

[0144] The configuration information of the candidate mapping table is used to indicate the configuration of the candidate mapping table.

[0145] According to the wireless communication method of the embodiment of the present disclosure, the configuration of the candidate mapping table can be indicated by sending the configuration information of the candidate mapping table, thereby allowing the candidate mapping table to be flexibly configured, for example, the specifications of the candidate mapping table can be adjusted, the candidate mapping table can be updated, etc. to adapt to a wide range of flexible application scenarios, thereby having higher wireless communication efficiency.

[0146] Exemplarily, according to a wireless communication method of yet another embodiment of the present disclosure, transmission control information and / or configuration information of the candidate mapping table is indicated through radio resource control signaling.

[0147] According to the wireless communication method of the embodiment of the present disclosure, transmission control information and / or configuration information of the candidate mapping table is indicated by radio resource control signaling, including the following technical solutions:

[0148] 1) Transmission control information is indicated through radio resource control signaling.

[0149] 2) The configuration information of the candidate mapping table is indicated through radio resource control signaling.

[0150] 3) The transmission control information and the configuration information of the candidate mapping table are indicated through radio resource control signaling.

[0151] It should be noted that the transmission control information may include an indication parameter of a target modulation and coding strategy combination and an indication parameter of a target mapping table. The transmission control information and / or configuration information of the candidate mapping table may also be indicated via downlink control information.

[0152] According to the wireless communication method of the embodiment of the present disclosure, transmission control information and / or configuration information of the candidate mapping table can be indicated in the form of radio resource control signaling. When the transmission control information and / or configuration information of the candidate mapping table is indicated in the form of radio resource control signaling, the transmission control information and / or configuration information of the candidate mapping table can be written into the communication protocol, and the transmission control information and / or configuration information of the candidate mapping table can be represented by adding parameters to the communication protocol.

[0153] It should also be noted that Radio Resource Control (RRC) signaling is used for signaling interaction in the radio resource control layer of the communication system. Since the radio resource control layer is located at the top layer, signaling interaction through radio resource control signaling to achieve transmission control is more complex and has a longer delay, and is suitable for scenarios with lower real-time performance. For example, when the transmission control information and / or the configuration information of the candidate mapping table is not adjusted for a long period of time, the transmission control information and / or the configuration information of the candidate mapping table can be indicated through radio resource control signaling.

[0154] Exemplarily, when the transmission control information and / or the configuration information of the candidate mapping table are indicated in the form of wireless resource control signaling, the transmission control information and / or the configuration information of the candidate mapping table in the form of wireless resource control signaling can be configured using information elements (IE) such as PDSCH-Config, PUSCH-Config, PDSCH-ConfigBroadcast of the wireless resource control layer, or new information elements can be defined to represent the transmission control information and / or the configuration information of the candidate mapping table in the form of wireless resource control signaling.

[0155] Exemplarily, the transmission control information may be indicated by, for example, downlink control information, and the configuration information of the candidate mapping table may be indicated by, for example, radio resource control signaling.

[0156] Generally, the real-time requirements for adjusting the target modulation and coding strategy combination and the target mapping table are relatively higher, and the real-time requirements for adjusting the configuration information of the candidate mapping table are relatively low. Therefore, the transmission control information can be indicated by downlink control information, for example, and the configuration information of the candidate mapping table can be indicated by wireless resource control signaling to adapt to the real-time requirements of both adjusting the transmission control information and adjusting the configuration information of the candidate mapping table, thereby having higher wireless communication efficiency.

[0157] Exemplarily, the wireless communication method according to yet another embodiment of the present disclosure may further include: receiving data attribute indication information of data to be transmitted.

[0158] The data attribute indication information is used to determine a target mapping table and / or a target modulation and coding strategy combination.

[0159] The data attributes of the data to be transmitted can characterize the characteristics of the data to be transmitted, and the characteristics of the data to be transmitted represented by the data attributes of the data to be transmitted can be matched and mapped with the target mapping table and / or the target modulation and coding strategy combination, so that the target mapping table and / or the target modulation and coding strategy combination can be accurately and efficiently determined according to the data attributes of the data to be transmitted, so as to utilize a variety of different modulation and coding strategies to modulate and encode the data to be transmitted with different characteristics, thereby realizing differentiated transmission and unequal protection.

[0160] For example, the data attributes of the data to be transmitted may include data type, error tolerance requirements, etc. Data types may include, for example, text data, audio data, image data, video data, etc. Error tolerance requirements may include, for example, error tolerance transmission indication information indicating lossy or lossless transmission, and the maximum transmission bit error rate that can be tolerated by the data to be transmitted.

[0161] An embodiment of the present disclosure further provides a wireless communication method. The wireless communication method of the exemplary embodiment of the present disclosure will be described below with reference to FIG5 in combination with the system architecture of FIG1 .

[0162] Fig. 5 schematically shows a flow chart of a wireless communication method 500 according to an embodiment of the present disclosure, which may be executed by, for example, at least one second communication subject shown in Fig. 1. The second communication subject is, for example, a user equipment.

[0163] In the case where there are multiple second communication entities, for example, the wireless communication method according to the embodiment of the present disclosure may be executed by each of the multiple second communication entities.

[0164] As shown in FIG5 , a wireless communication method 500 according to an embodiment of the present disclosure includes operations S510 to S520 .

[0165] In operation S510, configuration information of transmission control information is received.

[0166] The configuration information of the transmission control information is used to indicate the configuration of the transmission control information. The transmission control information includes an indication parameter of a target modulation and coding strategy combination. The indication parameter of the target modulation and coding strategy combination indicates multiple modulation and coding strategies. Each of the multiple modulation and coding strategies is used to modulate and encode the data to be transmitted to obtain the target data.

[0167] In operation S520, target data is received in case of downlink transmission, or is sent in case of uplink transmission.

[0168] It should be noted that when both the first communication subject and the second communication subject are one, the communication between the first communication subject and the second communication subject in the wireless communication method of the present embodiment is unicast communication. When the second communication subject includes multiple second communication subjects, the communication between the first communication subject and the second communication subject in the wireless communication method of the present embodiment is groupcast (multicast) or broadcast.

[0169] Unicast: Point-to-point communication between the first communication subject and the second communication subject within the same network.

[0170] Multicast: A first communication subject communicates with some of a plurality of second communication subjects within the same network reachable range.

[0171] Broadcast: The first communication subject communicates with all second communication subjects within the same network reachable range.

[0172] It should also be noted that the operation of the wireless communication method performed by the second communication subject in the embodiment of the present disclosure corresponds to the operation of the wireless communication method performed by the first communication subject in the embodiment of the present disclosure, and involves interaction between the two. Therefore, the technical principles and technical effects of the wireless communication method performed by the second communication subject are similar to those of the wireless communication method performed by the first communication subject, and will not be repeated here.

[0173] The wireless communication method according to another embodiment of the present disclosure may further include: sending data attribute indication information of the data to be transmitted.

[0174] The data attribute indication information is used to determine the target mapping table and / or target modulation and coding strategy combination. The target modulation and coding strategy combination is determined based on at least one candidate modulation and coding strategy combination. The target mapping table represents at least one candidate modulation and coding strategy combination. The transmission control information also includes indication parameters of the target mapping table.

[0175] It should be noted that when the user equipment sends data to be transmitted to the base station, the user equipment is, for example, the data source of the data to be transmitted, and the user equipment can obtain the data attributes of the data to be transmitted. Therefore, the user equipment can, for example, send data attribute indication information of the data to be transmitted to the base station.

[0176] According to yet another embodiment of the present disclosure, the wireless communication method may further include: receiving configuration information of a candidate mapping table.

[0177] The configuration information of the candidate mapping table is used to indicate the configuration of the candidate mapping table, and the target mapping table is determined according to at least one candidate mapping table.

[0178] Figure 6 schematically shows a schematic diagram of the interaction between a base station and a user equipment in an uplink transmission situation according to a wireless communication method of another embodiment of the present disclosure. Figures 6 and 7 are both explained by taking the first communication subject as a base station and the second communication subject as a user equipment as an example.

[0179] FIG7 schematically shows a schematic diagram of interaction between a base station and a user equipment in a downlink transmission case or a multicast broadcast service (MBS) case of a wireless communication method according to yet another embodiment of the present disclosure.

[0180] As shown in FIG6 , according to the wireless communication method of an embodiment of the present disclosure, in the case of uplink transmission, the base station may indicate the configuration information of the candidate mapping table to the user equipment via wireless control signaling, or the user equipment may also indicate the configuration information of the candidate mapping table to the base station. The candidate mapping table may also be pre-configured, for example. In the case of uplink transmission, the wireless communication method of an embodiment of the present disclosure may also, for example, directly have the user equipment send data attribute indication information of the data to be transmitted to the base station. The base station may match the target mapping table based on the data attribute indication information of the data to be transmitted, or may match the target mapping table and the indication parameters of the target modulation and coding strategy combination based on the data attribute indication information of the data to be transmitted. Of course, in the case where the user equipment does not send the data attribute indication information of the data to be transmitted to the base station, the base station may send the configuration information of the transmission control information to the user equipment, so that the user equipment can modulate and encode the data to be transmitted according to the multiple modulation and coding strategies indicated by the indication parameters of the target modulation and coding strategy combination to obtain the target data. The user equipment may send the target data to the base station, and the base station may receive the target data.

[0181] As shown in FIG7 , according to the wireless communication method of an embodiment of the present disclosure, in the case of downlink transmission or MBS, the base station may indicate configuration information of the candidate mapping table to the user equipment via wireless control signaling. The candidate mapping table may also be pre-configured, for example. The base station may send configuration information of the transmission control information to the user equipment. The base station may also modulate and encode the data to be transmitted using multiple modulation and coding strategies indicated by the indication parameters of the target modulation and coding strategy combination indicated by the indication parameters of the target modulation and coding strategy combination based on the configuration information of the transmission control information to obtain target data, and send the target data to the user equipment. The user equipment may decode the target data based on the transmission control information.
