For example, cellular phones and cars communicate with each other using sidelink signals. Cellular phones and smart home devices communicate without relaying communication signals through a base station.

[0032] The network device in this application embodiment can be a device for communicating with terminal devices. The network device may also include an access network device. The access network device can provide communication coverage for a specific geographical area and can communicate with the terminal device 120 located within that coverage area. The access network device can also be called a wireless access network device or a base station, etc. In this application embodiment, the access network device can refer to a radio access network (RAN) node (or device) that connects the terminal device to the wireless network.

[0033] Base stations can be fixed or mobile. For example, a helicopter or drone can be configured to act as a mobile base station, and one or more cells can move depending on the location of the mobile base station. In other examples, a helicopter or drone can be configured as a device to communicate with another base station.

[0034] Wireless communication systems involve communication equipment that can include not only access network equipment and terminal equipment, but also core network elements. Core network elements can be implemented through devices; that is, core network elements are core network devices. It can be understood that core network devices can also be a type of network device.

[0035] The core network elements in this application embodiment may include network elements that process and forward user signaling and data.

[0037] Network devices and terminal devices can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; they can also be deployed on water; and they can also be deployed in the air on airplanes, balloons, and satellites. This application does not limit the scenario in which the network devices and terminal devices are located.

[0038] It should be understood that all or part of the functions of the communication device in this application can also be implemented by software functions running on hardware, or by virtualization functions instantiated on a platform (e.g., a cloud platform).

[0039] Transport block (TB), code block (CB), and code block group (CBG)

[0040] In some communication systems (such as NR systems), a cyclic redundancy check (CRC) message can be added to a TB (Through Block) system, i.e., TB-level CRC information. TB-level CRC information is generated based on the entire TB. The receiver can determine whether the TB has been correctly decoded based on the TB-level CRC information.

[0041] A TB can be divided into multiple CBs, and each CB can have a CRC (CRC-level CRC) message added to it. Each CB can be encoded and decoded independently. The receiving end can determine whether the CB has been correctly decoded based on the CB-level CRC message.

[0042] A TB can also be divided into multiple CBGs. Each CBG consists of approximately equal numbers of CBs.

[0043] For a Test Block (TB), a hybrid automatic repeat request-acknowledgment (HARQ-ACK) message can be generated based on the TB, meaning one TB can correspond to one bit of HARQ-ACK information. If any CB in the TB fails to decode, the feedback message for that TB is a negative acknowledgment (NACK). If all CBs in the TB are successfully decoded, but the TB-level CRC check fails or fails, the feedback message for that TB is NACK. In other words, if either the CB-level CRC or the TB-level CRC check fails or fails, the feedback message for that TB is NACK.

[0044] In some implementations, HARQ-ACK information can be generated based on CBGs (Containment Block Groups). This involves dividing the CBs (Containment Blocks) within a TB (Block Module) into multiple CBGs, each containing at least one CB, with each CBG corresponding to 1 bit of HARQ-ACK information. If decoding fails for any CB in a CBG, the corresponding feedback information for that CBG is NACK. If all CBGs in the TB are successfully decoded, but the TB-level CRC check fails or fails, then the feedback information for all CBGs in the TB is NACK.

[0045] Wireless communication based on artificial intelligence (AI)

[0046] AI / machine learning (ML) based solutions are increasingly being used in wireless communication systems. Examples are provided below using Figures 2A-2C.

[0047] As shown in Figure 2A, the channel state information (CSI) feedback problem can be solved using AI. In Figure 2A, by introducing an AI encoder and an AI decoder, AI-based CSI information compression and feedback can be achieved.

[0048] As shown in Figure 2B, the channel estimation problem can be solved using AI. In Figure 2B, the AI ​​channel estimator enables high-performance estimation of a given channel.

[0049] As shown in Figure 2C, beam management problems can be solved using AI. In Figure 2C, an AI-based beam management algorithm can obtain optimal beam information, more refined beam information, or predictions of beam information at future moments based on known beam information.

[0050] It should be noted that AI-based wireless communication solutions are not limited to the examples mentioned above. In other words, AI solutions can address other problems. For example, AI / ML-based wireless AI solutions may also involve: AI-based modulation and demodulation, AI-based channel coding and decoding, AI-based precoding, AI / ML-based mobility management, AI / ML-based resource management, AI-based transceivers, AI-based integrated end-to-end transmission solutions, etc. Alternatively, even for the same problem, there can be a large number of other different AI solutions. Or, even for the same AI solution, different implementing entities can have different deployment and optimization schemes.

[0051] Performance monitoring of transmission schemes

[0052] For some transmission solutions, especially wireless AI transmission solutions, performance instability can occur during actual use due to limitations imposed by environmental, scenario, and channel conditions during design. Therefore, performance monitoring methods are needed to determine the operational status of the solution (e.g., a wireless AI transmission solution). For example, when a wireless AI solution is working normally, its current operational status should be maintained; when a wireless AI solution is malfunctioning, methods such as updating, switching, and rollback should be used to maintain the normal operation of the overall wireless transmission system.

[0053] In some use cases, performance evaluation of AI / ML solutions can be based on the inference results of the AI / ML solution to assess the performance of transmission-related intermediate results. This means judging the performance by comparing the output of the AI / ML model with the expected output. For example, for CSI compression and recovery solutions, the CSI recovery accuracy (or comparison with the expected accuracy) achievable by a specific AI / ML solution under specific compression feedback bit conditions can be used as a performance evaluation metric. This can be achieved by comparing the difference between ideal CSI information or the CSI information to be compressed and the CSI information obtained through compression and recovery. Similarly, for beam management solutions, the accuracy of beam prediction or the reference signal received power (RSRP) error of the predicted beam can be used as a basis for performance monitoring.

[0054] Characterization of transmission quality

[0055] The inventors of this application have discovered that there is a certain deviation between the transmission quality characterized in the related technologies and the actual transmission quality.

[0056] For example, in communication systems, the block error rate (BLER) is an important indicator of transmission quality. The inventors of this application have discovered that related technologies define, determine, or use BLER only at the granularity of TB (bits per second), which can lead to numerous problems. For instance, the BLER can easily cause a large transmission error representation (or represented transmission error) due to a small actual transmission error. For example, for the transmission of X TBs (e.g., X = 10), if each TB has Y CBs (e.g., Y = 16), in the extreme case where only one CB is actually faulty within each TB, the TB-granular BLER would determine that all X TBs are faulty, i.e., BLER = 100%. If the device obtaining this BLER is unable to make further judgments, it cannot distinguish whether all X multiplied by Y CBs (e.g., 10 × 16 = 160 CBs) are faulty or only some CBs are faulty, resulting in a large discrepancy between the actual transmission error (actual transmission error rate) and the represented transmission error (represented transmission error rate).

[0057] The deviation between the transmission quality described above and the actual transmission quality can adversely affect the communication process. The impact of this deviation on the selection of a transmission scheme will be explained below.

[0058] In relevant systems, the selection of the transmission scheme is closely related to the channel quality indicator (CQI). For example, relevant standards specify the following: A single PDSCH transport block, with a modulation scheme, target code rate, and transport block size corresponding to the CQI index, and occupying a group of downlink physical resource blocks termed the CSI reference resource, could be received with a transport block error probability (i.e., the BLER defined by TB granularity above) not exceeding 0.1 or 0.00001. If the higher-level parameter cqi-Table in CSI-ReportConfig is configured as 'table1' or 'table2', the transport block error rate will not exceed 0.1. If the higher-level parameter cqi-Table in CSI-ReportConfig is configured with 'table3', the transport block error rate will not exceed 0.00001.

[0059] Therefore, the performance of the BLER defined at the TB granularity (hereinafter referred to as TB BLER) will affect the selection of the current system transmission scheme. However, as mentioned above, using TB BLER as the basis for scheme selection can easily lead to a deviation between the actual transmission error and the represented transmission error, resulting in the selection of the transmission scheme not conforming to the actual transmission.

[0060] Figure 3 is a schematic flowchart of a wireless communication method provided in an embodiment of this application to solve the above-mentioned problems. The method shown in Figure 3 can be executed by a first device. The first device can be the communication device described above. For example, the first device may include a terminal device. Alternatively, the first device may include a network device.

[0061] The method shown in Figure 3 may include step S310.

[0062] Step S310: The first device determines the first transmission quality.

[0063] The first transmission quality can be a transmission quality determined by a first granularity. In other words, the first transmission quality is determined by a first granularity.

[0064] In some embodiments, the first transmission quality may include, for example, a correct rate and / or an error probability calculated based on a first granularity. The error rate can characterize the proportion of incorrectly received first-granularity data among a plurality of received first-granularity data. The correct rate can characterize the proportion of correctly received first-granularity data among a plurality of received first-granularity data. Wherein, if data is received and successfully decoded (or decrypted), the data can be considered correctly received; correspondingly, if data decoding fails, the data can be considered not correctly received. Therefore, the error rate can also be referred to as the failure rate, transmission failure rate, or parsing failure rate. The correct rate can also be referred to as the success rate, transmission success rate, or decoding success rate.

[0065] For example, the first device can perform statistics on multiple received data of first granularity to calculate a first transmission quality. For instance, the first device can count one or more of the following: the number of first granularity data that failed to transmit, the number of first granularity data that successfully transmitted, and the total number of first granularity data transmitted. If the first transmission quality includes accuracy, the accuracy can be equal to the number of successfully transmitted first granularity data divided by the total number of first granularity data transmitted. If the first transmission quality includes error rate, the error rate can be equal to the number of first granularity data that failed to transmit divided by the total number of first granularity data transmitted.

[0066] When the first transmission quality includes the error rate, the error rate of the first granularity can also be referred to as the first granularity BLER.

[0067] It is understood that this application can determine the first transmission quality based on the granularity that conforms to the actual transmission situation, so that the characterized transmission quality can more accurately represent the actual transmission quality.

[0068] In some embodiments, the first device may determine whether data of multiple first granularities has been correctly received. As described above, whether data has been correctly received can be determined by whether it has been correctly decoded.

[0069] For example, whether the data was received correctly can be determined by the CRC result. The CRC result can include whether the CRC check passed or failed (or the CRC check failed). For instance, if the CRC check passes, it can be determined that the data at that first granularity was received correctly. Conversely, if the CRC check fails, it can be determined that the data at that first granularity was not received correctly.

[0070] In some embodiments, the length of the first granularity may be less than or equal to TB. That is, the first granularity may include: TB granularity and / or granularity smaller than TB. Exemplarily, the first granularity may include one or more of the following: TB granularity, CB granularity, CBG granularity.

[0071] Taking a first granularity including CB granularity as an example, the first device can determine the first transmission quality based on whether multiple CBs were correctly received. For instance, when the first granularity includes CB granularity, the first transmission quality can include the block error rate (hereinafter referred to as CB BLER, or CB error probability) at the CB granularity. If the CRC checksum of a CB (CB-level CRC) fails, the CB transmission is considered to have failed. The first device can statistically analyze the transmission results of the received CBs to obtain the CB BLER.

[0072] For example, if X CBs are transmitted and X1 CBs are transmitted incorrectly, then the block error rate information at the CB granularity can be the X1 transmission errors out of the X CBs, i.e., the CB BLER is X1 / X.

[0073] Taking a first granularity including CBG granularity as an example, the first device can determine the first transmission quality based on whether multiple CBGs were received correctly. For example, when the first granularity includes CBG granularity, the first transmission quality can include the block error rate (hereinafter referred to as CBG BLER, or CBG error probability) at the CBG granularity. If the CRC checksum of a CBG (CBG-level CRC) fails, the CBG transmission is considered to have failed. The first device can statistically analyze the transmission results of the received CBGs to obtain the CBG BLER.

[0074] For example, if there are Y CBG transmissions and Y1 CB transmission errors, then the block error rate information at the CBG granularity can be the Y1 transmission errors out of the Y CBGs, i.e., the CBG BLER is Y1 / Y.

[0075] Taking a first granularity including TB granularity as an example, the first device can determine the first transmission quality based on whether multiple TBs were received correctly. For instance, when the first granularity includes TB granularity, the first transmission quality can include the TB granularity's block error rate (hereinafter referred to as TB BLER). If the CRC checksum of a TB (TB-level CRC) fails, the TB transmission is considered to have failed. The first device can statistically analyze the transmission results of the received TBs to obtain the TB BLER.

[0076] For example, if there are Z TB transmissions and Z1 CB transmission errors, then the block error rate information at the TB granularity can be the Z1 transmission errors out of the Z TBs, that is, the TB BLER is Z1 / Z.

[0077] This application allows for defining BLERs with a granularity of length less than or equal to TB, thereby enabling more accurate characterization of smaller actual transmission errors. Continuing with the example above, for X (e.g., X = 10) TB transmissions, if each TB has Y (e.g., Y = 16) CBs, and only one CB actually fails within each TB, the CB-granularity-based BLER would determine that Y CBs are faulty, i.e., CB BLER = Y / (X × Y) = 10%. The device obtaining this CB BLER can determine that one out of ten CBs is faulty, thus making the actual transmission error and the characterized transmission error closer together.

[0078] Besides the BLER representation described above, the first transmission quality can also be other forms of transmission quality levels determined at a first granularity. For example, different error rate levels can be determined by classifying transmission results (e.g., whether transmission was successful). Examples include percentage representations of BLER results (CB BLER, CBG BLER, TB BLER). Another example is a bitwise representation of BLER results (CB BLER, CBG BLER, TB BLER) (different bits represent different CB, CBG, or TB transmission qualities, whether transmission was successful, etc.).

[0079] In some embodiments, the first device may send second information to the second device. The second information may be used to indicate whether the first device can determine the first transmission quality.

[0080] In some embodiments, the second information may indicate the granularity of determination corresponding to the first transmission quality that the first device can determine. As described above, the first granularity may include one or more of CB, CBG, and TB. Based on this, the second information may be used, for example, to indicate whether the first device can determine one or more of the following: the first transmission quality at the CB granularity (e.g., CB BLER), the first transmission quality at the CBG granularity (e.g., CBG BLER), and the first transmission quality at the TB granularity (e.g., TB BLER).

[0081] This application does not limit the message carrying the second information. For example, if the first device includes a terminal device, the second information can be reported via capability information. Alternatively, if the first device includes a network device, the second information can be reported via a broadcast message. Furthermore, the second information can be carried in one or more of the following messages: radio resource control (RRC) messages, downlink control information (DCI), medium access control control element (MAC CE), uplink control information (UCI), etc.

[0082] In some embodiments, the first transmission quality can be used to determine a first transmission scheme. For example, the first device can determine the first transmission scheme itself based on the first transmission quality. Alternatively, the first device can send the first transmission quality to a second device, which can then determine the first transmission scheme.

[0083] The first transmission quality can be obtained through performance monitoring of the first transmission scheme. By monitoring the performance of the first transmission scheme, the first transmission quality can be obtained, and the first transmission scheme can be adjusted and managed based on the first transmission quality.

[0084] In some embodiments, the first transmission scheme may include one or more of the following: modulation scheme, coding rate, transport block size, coding block set size, coding block size, modulation and coding scheme (MCS) level, channel quality indicator (CQI) indication, and CSI reporting.

[0085] In some embodiments, the first transmission scheme may include an AI transmission scheme.

[0086] As mentioned above, the granularity of the first transmission quality is the first granularity. Determining the first transmission scheme based on the first transmission quality can determine a transmission scheme that better reflects the actual transmission situation. For example, when the first granularity is less than TB, the granularity of adjusting the first transmission scheme can be less than TB, that is, refining the granularity of adjusting the transmission scheme in related technologies, thereby avoiding the problem of poor transmission scheme selection. Taking the first granularity as CB granularity or CBG granularity as an example, determining the first transmission granularity based on the first transmission quality can refine the BLER granularity of adjusting the transmission scheme, avoiding the problem of poor transmission scheme (e.g., CQI) selection caused by a large TB BLER due to a small number of CB or CBG transmission errors.

[0087] Furthermore, for some transmission schemes, such as AI-based wireless transmission schemes, performance monitoring may not always be achievable through intermediate metrics (such as channel estimation performance, CSI feedback performance, measurement quality performance, beam estimation performance, etc.). For example, for AI receivers and AI transceivers, if the receiving end directly outputs data parsing results for the system, a corresponding performance monitoring scheme needs to be designed to perform effective performance monitoring based on the obtained data parsing results, as well as the management of related schemes, such as updates, switching, and rollback. As mentioned above, the first transmission scheme may include an AI book-breaking scheme. In particular, the first transmission scheme may include AI transmission schemes that cannot perform intermediate result detection. This application introduces a more suitable definition of transmission performance metrics (i.e., the definition of first transmission quality) to meet the monitoring needs of transmission schemes, thereby enabling lifecycle management of corresponding transmission schemes based on this transmission performance metric. For example, performance monitoring of transmission schemes (such as AI transmission schemes, AI receivers, etc.) can be performed based on different levels of BLER (such as one or more of CB BLER, CBG BLER, and TB BLER mentioned above).

[0088] Optionally, the first transmission scheme is a transmission scheme with a second granularity. For example, the second granularity may include one or more of the following: CB granularity, CBG granularity, and TB granularity. That is, the first transmission scheme with the second granularity can be determined based on the first transmission quality of the first granularity.

[0089] It should be noted that the first granularity can be the same as or different from the second granularity. For example, when considering data transmission at the CB granularity, the first transmission scheme can be determined based on one or more of the transmission quality at the CB granularity, the CBG granularity, and the TB granularity. Similarly, when considering data transmission at the CBB granularity, the first transmission scheme can be determined based on one or more of the transmission quality at the CB granularity, the CBG granularity, and the TB granularity. Likewise, when considering data transmission at the TB granularity, the first transmission scheme can be determined based on one or more of the transmission quality at the CB granularity, the CBG granularity, and the TB granularity.

[0090] In some embodiments, when determining the first transmission scheme, the first transmission quality needs to meet a first condition.

[0091] For example, when considering the transmission of transport block TB, when determining the first transmission scheme (e.g., modulation scheme, coding rate, transport block size, coding block set size, coding block size, MCS level, CQI indication, CSI reporting), it is necessary to ensure that the first transmission quality meets the first condition.

[0092] For example, when considering the transmission of the coded block set CBG, when determining the first transmission scheme (e.g., modulation scheme, coding rate, transport block size, coded block set size, coded block size, MCS level, CQI indication, CSI reporting), it is necessary to ensure that the first transmission quality meets the first condition.

[0093] For example, when considering the transmission of coded blocks (CBs), when determining the first transmission scheme (e.g., modulation scheme, coding rate, transport block size, coded block set size, coded block size, MCS level, CQI indication, CSI reporting), it is necessary to ensure that the first transmission quality meets the first condition.

[0094] In some embodiments, the first condition includes one or more of the following: when the first transmission quality includes a block error rate at the CB granularity, the block error rate at the CB granularity is less than or equal to a first threshold; when the first transmission quality includes a block error rate at the CBG granularity, the block error rate at the CBG granularity is less than or equal to a second threshold; when the first transmission quality includes a block error rate at the TB granularity, the block error rate at the TB granularity is less than or equal to a third threshold.

[0095] The first threshold value can satisfy one or more of the following: protocol-predefined, network device-determined or configured, or pre-configured.

[0096] This application does not limit the value of the first threshold. For example, the first threshold can be 10% (i.e., the first condition including CB BLER cannot exceed 10%). Alternatively, for a specific transmission, the first threshold is 0.001% (i.e., the first condition including CB BLER cannot exceed 0.001%).

[0097] The second threshold value can satisfy one or more of the following: protocol-predefined, network device-determined or configured, or pre-configured.

[0098] This application does not limit the value of the second threshold. For example, the second threshold can be 10% (i.e., the first condition including CBG BLER cannot exceed 10%). Alternatively, for a specific transmission, the second threshold is 0.001% (i.e., the first condition including CBG BLER cannot exceed 0.001%).

[0099] The third threshold can satisfy one or more of the following: protocol-predefined, network device-determined or configured, or pre-configured.

[0100] This application does not limit the value of the third threshold. For example, the third threshold can be 10% (i.e., the first condition includes that the TB BLER cannot exceed 10%). Alternatively, for a specific transmission, the third threshold can be 0.001% (i.e., the first condition includes that the TB BLER cannot exceed 0.001%).

[0101] The following examples, 1 to 3, illustrate how to determine the first transmission scheme.

[0102] Example 1: A single PDSCH (or PDCCH) transport block (TB) with a given transmission scheme must ensure that the error rate of the received code block (or CBG) does not exceed a threshold T. The transmission scheme can be, for example, a combination of modulation scheme, target code rate, and transport block size corresponding to the CQI index, occupying a group of downlink physical resource blocks termed the CSI reference resource. The threshold T can be, for example, 0.1, 0.01, 0.001, 0.0001, 0.00001, or 0.000001, etc.

[0103] Example 2: A transmission scheme for a PDSCH (or PDCCH) code block group (CBG) must ensure that the error rate of the received CB, CBG, or TB does not exceed a threshold T. The transmission scheme can be, for example, a combination of modulation scheme, target code rate, and transport block size corresponding to the CQI index, occupying a group of downlink physical resource blocks termed the CSI reference resource. The threshold T can be, for example, 0.1, 0.01, 0.001, 0.0001, 0.00001, or 0.000001, etc.

[0104] Example 3: A PDSCH (or PDCCH) code block (CB) transmission scheme must ensure that the error rate of the received CB, CBG, or TB does not exceed a threshold T. The transmission scheme can be, for example, a combination of modulation scheme, target code rate, and transport block size corresponding to the CQI index, occupying a group of downlink physical resource blocks termed the CSI reference resource. The threshold T can be, for example, 0.1, 0.01, 0.001, 0.0001, 0.00001, or 0.000001, etc.

[0105] In some embodiments, the method shown in FIG3 can also be performed by a second device. The second device can be a communication device that interacts with the first device. For example, the first device may include a terminal device, and the second device may include a network device. Alternatively, the first device may include a network device, and the second device may include a terminal device.

[0106] The method shown in Figure 3 may include step S320.

[0107] In step S320, the first device sends first information to the second device. The first information can be used to indicate the first transmission quality.

[0108] As described above, the first device may include a terminal device, and the second device may include a network device. In this case, the first transmission quality can be the transmission quality of downlink transmission (i.e., transmission from the network device to the terminal device). That is, the terminal device can report the first transmission quality to the network device through the first information. As shown in Figure 4A, the UE can report the first transmission quality to the network device.

[0109] As described above, the first device may include a network device, and the second device may include a terminal device. In this case, the first transmission quality can be the transmission quality of the uplink transmission (i.e., the transmission from the terminal device to the network device). That is, the network device can indicate the first transmission quality to the terminal device through the first information. As shown in Figure 5A, the network device can indicate the first transmission quality to the UE.

[0110] In some embodiments, the second device may send first trigger information to the first device. The first trigger information can be used by the second device to trigger the first device to send first information. That is, in response to receiving the first trigger information, the first device may send first information. Examples are given below with reference to Figures 4B and 5B.

[0111] As shown in Figure 4B, the network device can send a first triggering message to the terminal device to trigger the reporting of a first transmission quality. Based on the first triggering message, the terminal device can report the first transmission quality accordingly.

[0112] As shown in Figure 5B, the terminal device can send a first trigger message to the network device to trigger the network device to indicate a first transmission quality. Based on the first trigger message, the network device can correspondingly indicate the first transmission quality.

[0113] In some embodiments, the first device may send a first request message to the second device. The first request message can be used by the first device to request the sending of first information to the second device. That is, if the first device wishes to send first information to the second device, it can request the sending of first information to the second device through the first request message.

[0114] Based on the first request information, the second device can determine whether to allow the first device to send the first information. For example, the second device can send first indication information to the first device. The first indication information can be used by the second device to instruct the first device to send the first information based on the first request information, that is, the second device accepts the first device's request and allows the first device to send the first information. For example, the first indication information can instruct the first device to send the first information. In this case, the terminal device can send the first information to the second device based on the indication of the first indication information. Alternatively, the first indication information can instruct the first device not to send the first information, that is, the second device rejects the first device's request and does not allow the first device to send the first information. In this case, the terminal device can not send the first information to the second device based on the indication of the first indication. The following explanation uses Figure 4C as an example.

[0115] In Figure 4C, the UE sends a first request message to the network device to request the reporting of a first transmission quality. Upon receiving the first request message, the network device sends a first indication message to the UE, instructing the UE to report the first transmission quality. Upon receiving the first indication message, the UE, according to the instructions in the first indication message, sends first information to the network device to report the first transmission quality.

[0116] It should be noted that this application does not limit the method of sending the first information. For example, the first information can be sent periodically, and / or triggered by an event.

[0117] It should be noted that this application does not limit the method of sending the first request information. For example, the first request information may be sent by an event.

[0118] When the first message is sent periodically, the configuration for periodic reporting can satisfy one or more of the following: protocol definition, network device determination or configuration.

[0119] When the first information or the first request information is sent in response to an event, the first device may send the first information or the first request information when the first event occurs or the second condition is met.

[0120] As one possible implementation, the first event or second condition may include: the first transmission quality is worse than (or not better than) a first threshold. For example, if the first transmission quality includes an error rate, the first event or second condition may include: the error rate is greater than or equal to the first threshold. Similarly, if the first transmission quality includes an accuracy rate, the first event or second condition may include: the accuracy rate is less than or equal to the first threshold.

[0121] As one possible implementation, the first event or second condition may include: the number of times the first transmission quality is worse than (or not better than) a first threshold exceeds a second threshold. The second threshold can be a positive integer. For example, the first event or second condition may include: within a first monitoring window, the number of times the first transmission quality is worse than (or not better than) the first threshold exceeds the second threshold. The first monitoring window can be a period of time. The first monitoring window can satisfy one or more of the following: predefined, determined by the network device, or configured. The second threshold can be a positive integer. The second threshold can satisfy one or more of the following: predefined, determined by the network device, or configured.

[0122] For example, a first transmission quality that is worse than (or not better than) a first threshold may include one or more of the following: CB BLER, CBG BLER, TB BLER, CB decoding success rate, and CBG decoding success rate.

[0123] It should be noted that the first threshold may include one or more specific thresholds. When the first transmission quality includes multiple parameters, the first threshold may include a corresponding number of specific thresholds.

[0124] It should be noted that the first threshold can satisfy one or more of the following: predefined, determined by the network device, or configured.

[0125] Therefore, it can be seen that when the first event is detected or the second condition is met, the first device can send the first information. Thus, the first event can be called a sending event or a reporting event. The second condition can also be called a monitoring condition, a sending condition, or a reporting condition, etc.

[0126] It should be noted that the first event or the second condition can satisfy one or more of the following: predefined, determined by the network device, or configured.

[0127] It should be noted that this application does not limit the form in which the first information indicates the first transmission quality. For example, the first information may include one or more of the following: a value corresponding to the first transmission quality, a level corresponding to the first transmission quality, a bitmap corresponding to the first transmission quality, and a percentage corresponding to the first transmission quality. Exemplarily, the form in which the first information indicates the first transmission quality may satisfy one or more of the following: protocol definition, network device determination or configuration.

[0128] It should be noted that this application does not limit the method for determining the first transmission quality indicated in the first information. For example, the method for determining the first transmission quality indicated in the first information may satisfy one or more of the following: protocol definition, network device determination or configuration.

[0129] It should be noted that this application does not limit the transmission resources occupied by the first information. For example, the transmission resources occupied by the first information may satisfy one or more of the following: protocol definition, network device determination or configuration.

[0130] When the first device includes a terminal device and the second device includes a network device, the reasons or conditions under which the terminal device needs to report the first information are as follows: For example, if the network device needs to know the transmission performance of the current downlink transmission scheme on the terminal device side, the terminal device can report the first information. Another example is when the base station does not configure the terminal device to perform HARQ-related feedback, but the network device needs to know the transmission performance of the current downlink transmission scheme on the terminal device side, the terminal device can report the first information. Yet another example is that, for a specific transmission service, the terminal device can report the first information. Specific transmission services may include, for example, one or more of the following: bit-level error-insensitive transmission services, transmission of large-scale datasets, and / or semantic communication. Yet another example is that, for an AI-based transmission scheme, the network device needs the first transmission quality of the current transmission scheme to determine whether to update, switch, or fall back to the current transmission scheme.

[0131] When the first device includes a network device and the second device includes a terminal device, the reasons or conditions under which the network device needs to report the first information are as follows. For example, when the terminal device needs to know the transmission performance of the current uplink transmission scheme on the network side, the network device can send the first information. Another example is that the network device can send the first information for specific transmission services. Specific services may include one or more of the following: bit-level error-insensitive transmission services, transmission of large-scale datasets, and / or semantic communication. Yet another example is that for AI-based transmission schemes, when the terminal device needs the first transmission quality of the current transmission scheme to determine whether to update, switch, or fall back to the current transmission scheme, the network device can send the first information.

[0132] When a network device configures or sends certain information (such as first information, first trigger message, first threshold, etc.), this information can be carried in one or more of the following messages: broadcast message, RRC message, MAC CE, DCI message, downlink message in random access procedure, PDSCH, AI / ML dedicated downlink channel, and network-side capability indication message. Broadcast messages may include, for example, one or more of the following: MIB, SIB1, SIBx. Downlink messages in random access procedure may include, for example, one or more of the following: message B (MsgB), Msg2, Msg4.

[0133] When a terminal device configures or sends certain information (such as first information, first request message, etc.), this information can be carried in one or more of the following messages: RRC message, UCI message, uplink message during random access procedure, PUCCH, PUSCH, AI / ML dedicated uplink channel, UE capability reporting. Uplink messages during random access procedure may include, for example, one or more of the following: MsgA, Msg3.

[0134] In some implementations, the second information sent by the first device can be used to indicate whether the first device is able to send the first information. In conjunction with the content of the second information described above, the second information can be used to indicate whether the first device is able to determine the first transmission quality and / or send the first information.
