Description

Technical Field

[0001] This disclosure relates to the field of wireless communication technology, and in particular to an information transmission method, device, storage medium, and computer program product. Background Technology

[0002] Channel State Information (CSI) reporting is a crucial process in wireless communication. It involves terminals (such as UEs) reporting channel states to base stations (such as eNodeBs or gNBs) so that the base station can optimize downlink transmission based on the channel conditions. In traditional CSI reporting, the payload occupied by the Precoding Matrix Indicator (PMI) corresponding to different stream numbers is determined by the base station configuration parameters.

[0003] However, traditional CSI reporting faces challenges when handling multi-stream transmission, especially the lack of flexibility in configuring PMI payloads and the failure to optimize for multi-stream characteristics, which limits its application in efficient multi-stream scenarios.

[0042] To make the objectives, technical solutions, and advantages of this disclosure more apparent, exemplary embodiments according to this disclosure will now be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of this disclosure, and not all embodiments of this disclosure. It should be understood that this disclosure is not limited to the exemplary embodiments described herein.

[0043] Figure 1 This is a schematic diagram of a communication system according to an embodiment of the present disclosure.

[0044] like Figure 1 As shown, the communication system 100 may include a network device 101 and a terminal device 102. The network device 101 can communicate with the terminal device 102 wirelessly. During the communication between the network device 101 and the terminal device 102, the network device 101 can configure appropriate Channel State Information-Reference Signal (CSI-RS) resources or synchronization signals and PBCH blocks (SSBs) for the terminal device 102. Then, the terminal device measures the CSI-RS or SSB and calculates the required Channel State Information (CSI), and reports the CSI. The network device will then perform scheduling adjustments and beam management related tasks based on the reported content.

[0045] Terminal equipment can be user equipment (UE), access terminal, user unit, user station, mobile station, mobile station, remote station, remote terminal, mobile device, user terminal, smart terminal, wireless communication equipment, user agent, or user device. Terminal equipment can also be cellular phones, cordless phones, Session Initiation Protocol (SIP) phones, Wireless Local Loop (WLL) stations, Personal Digital Assistants (PDAs), handheld devices with wireless communication capabilities, computing devices or other processing devices connected to a wireless modem, relay equipment, vehicle-mounted equipment, wearable devices, terminals in next-generation communication systems such as NR networks, or terminals in future evolved Public Land Mobile Networks (PLMNs). Network equipment can be a base station (BS), also known as base station equipment, which is a device deployed in a radio access network to provide wireless communication capabilities. For example, in 2G networks, equipment providing base station functionality includes Base Transceiver Stations (BTS) and Base Station Controllers (BSCs); in 3G networks, it includes Node Bs (NodeBs) and Radio Network Controllers (RNCs); in 4G networks, it includes evolved Node Bs (eNBs); in Wireless Local Area Networks (WLANs), it is the Access Point (AP); in 5G New Radio (NR), it includes further evolved Node Bs (gNBs); and it includes equipment providing base station functionality in future communication systems. No specific limitations are imposed.

[0046] Understandable. Figure 1 The form and quantity of network devices and terminal devices shown are for illustrative purposes only and do not constitute a limitation on the embodiments of this disclosure.

[0047] In traditional CSI reporting, the PMI load for different flow numbers is determined by base station configuration parameters, and the number of CPUs (CPU specifically refers to the processing power or units required by the terminal device during CSI measurement and reporting) for different flow numbers is also the same. However, for CSI compression use cases in multi-flow scenarios, the 3rd Generation Partnership Project (3GPP) has proposed several potential model deployment methods, but the CSI load design and CPU calculation methods for different model deployment methods may differ.

[0048] If four streams need to be transmitted, the terminal needs to allow four model inferences. The number of bits required for PMI (Programmable Memory Interface) is four times that of PMI for a single-stream transmission, and the computational complexity of CSI (Computational SI) is also four times that of a single-stream transmission. However, considering that the payload of different layers can be different in multi-stream transmission to ensure that lower layers have relatively more bits, and that the CPU usage varies with the number of streams, it is necessary to enhance the CSI payload and CPU computation methods.

[0049] Based on the above issues, this disclosure is made.

[0050] Figure 2 This is a schematic flowchart illustrating an information transmission method according to an embodiment of the present disclosure.

[0051] like Figure 2 As shown, an information transmission method according to an embodiment of this disclosure can be executed by a terminal device, and the method specifically includes the following steps.

[0052] Step 201: Send a first message, which indicates the payload-related information occupied by the third information carried in the second message supported by the terminal device; or send a second message, which carries the payload-related information occupied by the third information; or receive a fifth message, which indicates the payload-related information occupied by the third information carried in the second message supported by the terminal device.

[0053] Specifically, the second message can be channel state information, used to help network devices understand channel conditions. The third information can include, but is not limited to, one or more of channel information, precoding information, and precoding matrix information. The aforementioned payload-related information can include, but is not limited to, the payload range occupied by at least one level of third information supported by the terminal device, the maximum and / or minimum value of the payload occupied by at least one level of third information supported by the terminal device, the payload range occupied by at least one rank of third information supported by the terminal device, the maximum and / or minimum value of the payload occupied by at least one rank of third information supported by the terminal device, the payload range occupied by the third information carried in the second message, and the maximum and / or minimum value of the payload occupied by the third information carried in the second message. Here, "stream" refers to a data stream (or layer), and one data stream typically corresponds to transmission on a spatial sub-channel. "Rank" refers to the rank of the channel matrix, which determines the number of independent data streams (or layers) that can be transmitted simultaneously. Rank can also be represented by RI, which is the rank indicator.

[0054] In one embodiment of this disclosure, a first message is sent by a terminal device to a network device to indicate to the network device the payload-related information occupied by the third information carried in a second message that the terminal device supports sending to the network device. By sending the first message to the network device, the terminal device helps the network device understand the terminal's capabilities in advance, thereby optimizing subsequent processing flows. Here, the first message may include, but is not limited to, notification messages, indication messages, etc. In order to conduct communication, the terminal device may actively or passively (e.g., in response to a request from the terminal side) send an indication message to a second device to indicate the payload-related information occupied by the third information carried in the second message that the terminal device supports sending to the network device. For example, the terminal device may inform the network device by sending the first message the payload-related information occupied by the third information (e.g., channel information, precoding information, precoding matrix information, etc.) carried by the channel state information it supports.

[0055] In one embodiment of this disclosure, the terminal device can send a second message (such as channel state information) to the network device to inform the network device of the payload-related information occupied by third information (e.g., channel information, precoding information, precoding matrix information, etc.). For example, in order to conduct communication, the terminal device can report channel state information to a second device to inform the network device of the payload-related information occupied by channel information, precoding information, precoding matrix information, etc. This allows the network device to understand the terminal device's reporting capability and current channel conditions in real time, thereby enabling more accurate resource allocation and transmission optimization.

[0056] In one embodiment of this disclosure, the fifth message is sent by the network device to the terminal device, instructing the terminal device to send the payload-related information of the third information carried in the second message to the network device. After receiving the fifth message, the terminal device can parse and identify the received fifth message to understand the specific requirements of the network device for its CSI report. Based on the parsing results, the terminal device determines which payload-related information of the third information should be included in the subsequent second message.

[0057] For example, the supported CSI may include the range, maximum, or minimum value of the load-related information corresponding to at least one rank value in the PMI (RI∈[1,RI)). max ], where RI max It is the maximum number of streams that the terminal device reports or a predefined value that it supports.

[0058] In summary, according to the technical solution provided in this disclosure, the terminal device sends a first message to the network device, informing it of the payload-related information occupied by the third information sent in the second message. This approach allows the terminal device to declare its capabilities in advance, helping the network device to prepare or optimize its processing flow. The terminal device directly informs the network device of the supported payload-related information by carrying payload-related information in the second message. This eliminates the need to send a separate message to indicate capabilities or configuration, simplifying the interaction process and making data transmission more direct and efficient, especially suitable for scenarios requiring rapid response. By receiving the fifth message, the terminal device can provide payload-related information according to the network device's instructions, enhancing the network device's control. The aforementioned configuration of payload-related information occupied by each flow by the network device or reporting by the terminal device ensures that the PMI corresponding to more important layers occupies a relatively larger number of bits, guaranteeing efficient utilization of uplink control information (UCI) bits.

[0059] Furthermore, the second message comprises a first part and a second part, wherein the first part of the second message comprises one or more of the following:

[0060] The rank indicator of the second information, the payload-related information occupied by at least the first-order third information of the second information, and the payload-related information occupied by the third information carried by the second message.

[0061] In embodiments of this disclosure, the second message (such as CSI) may include a first part and a second part. The first part may include, but is not limited to, one or more of the following: a rank indicator of the second information, payload-related information occupied by at least one first-order third information of the second information, and payload-related information occupied by the third information carried in the second message. Thus, by sending or indicating a second message containing the aforementioned information to the network device, the terminal device can provide the network device with detailed information about its current channel state and capabilities. This allows the network device to quickly understand the number of data streams the terminal device can support under the current channel conditions through the rank indicator, facilitating rapid resource allocation and scheduling, and selection of the most suitable transmission strategy, thereby improving communication efficiency. Through the payload-related information occupied by at least one first-order third information of the second information and the payload-related information occupied by the third information carried in the second message, the terminal device provides the network device with direct feedback on the level of detail of the Channel State Information (CSI). Based on this information, the network device can more accurately assess the feedback capabilities and needs of the terminal device, thereby optimizing resource allocation, such as adjusting the coding rate, modulation scheme, or allocating more resources to terminal devices requiring higher-precision CSI.

[0062] In summary, according to the technical solutions provided in the embodiments of this disclosure, by including one or more of various information (rank indicator, payload-related information, etc.) in the first part, the network device can be customized according to different communication scenarios and needs. This achieves a comprehensive improvement in communication efficiency, resource allocation, system flexibility, and user experience.

[0063] Furthermore, if the first part of the second message includes payload-related information occupied by the third information carried by the second message, the second part of the second message includes payload-related information occupied by at least the first-order third information carried by the second message.

[0064] Specifically, the terminal device sends a second message to the network device, reporting to the network device the first part of the second message, which includes the payload-related information occupied by the third information carried in the second message, and the second part, which includes the payload-related information occupied by at least the first-order third information carried in the second message.

[0065] In summary, the first and second parts of the second message complement each other in providing payload-related information. The first part provides payload-related information occupied by the third information carried by the channel state information, while the second part provides more detailed and specific data stream-level payload-related information. This design helps network devices to have a more comprehensive understanding of the channel state and requirements of terminal devices, thereby making more reasonable scheduling and resource allocation decisions.

[0066] Furthermore, the first part of the second message may also include a third parameter, which is used together with other network device configuration parameters to determine the load-related information occupied by the third information (such as PMI) for each flow. This increases the system's flexibility and configuration capabilities. For example, the load-related information / third parameters reported by the terminal device for each flow can be the same or different; when the load / third parameters for each flow are the same, only one load-related information / third parameter can be configured. Thus, based on the rank indicator RI value carried in the second message, the terminal device can determine which flow the reported PMI corresponds to, and then determine the load-related information occupied by the third information (such as PMI) for each flow through the third parameter.

[0067] Here, other network device configuration parameters include: CSI reporting bandwidth and the number of CSI-RS ports.

[0068] Furthermore, the first part of the second message may also include a third parameter, which, together with other network device configuration parameters, determines the payload-related information occupied by the third information (such as PMI). The network device can determine, based on the third parameter, the payload-related information occupied by the third information (such as PMI) in the first part of the received second message, and thus determine the payload-related information that the second part needs to occupy.

[0069] Furthermore, the second part of the second message may also include a third parameter, which is used together with other network device configuration parameters to determine the load-related information occupied by each first-order third message (such as PMI).

[0070] Furthermore, the first part of the second message includes at least the third information of at least one stream of the second message.

[0071] Specifically, the terminal device sends a second message to the network device, the first part of which carries at least one third stream information (such as PMI).

[0072] Furthermore, the first part of the second message may also include at least a first-level portion corresponding to the third information and a rank indicator RI. The third information of the remaining streams, or portions of the third information corresponding to other streams, can be reported to the network device through the second part of the second message. By sending a second message carrying the rank indicator RI to the network device, the terminal device can inform the network device of the maximum number of data streams (or layers) that can be used in downlink transmission. Even if only one data stream is currently being transmitted, the value of RI may indicate that the network has the capacity to support more data streams.

[0073] In summary, according to the technical solution provided in the embodiments of this disclosure, in a multi-stream CSI reporting scenario, the first part of the second message includes third information of at least one stream of the second message. Even if the second part of the second message is discarded, it can still be guaranteed that the network device receives at least one stream of third information (such as PMI) based on the received second message. Although the third information of multiple streams (such as PMI) cannot be known, the network device can still perform single-stream scheduling of service channels based on at least one stream of third information (such as PMI).

[0074] Furthermore, the above information transmission method further includes: determining the unit or capability corresponding to processing the second message based on at least one or more of the following: resources for channel measurement, the stream of the second information, the terminal device for at least a first-order processing unit or capability, the rank of the second information, and the terminal device for at least a rank processing unit or capability.

[0075] Specifically, the terminal device can calculate the unit or capability corresponding to the second message based on one or more of the following: channel measurement resources, the flow of the second information, the terminal device's processing unit or capability for at least one first-order, the rank of the second information, and the terminal device's processing unit or capability for at least one rank.

[0076] Furthermore, the unit or capability corresponding to processing the second message is determined based on one or more of the resources used for channel measurement, the maximum number of streams supported by the terminal device, and the processing unit or capability required by the terminal device to process at least one stream.

[0077] When a terminal device processes all streams of all ranks using the same first processing model, or when a terminal device processes different streams of the same rank using different second processing models, the unit or capability corresponding to the processing of the second message can be determined by referring to the following method.

[0078] For example, suppose the number of resources in the Channel State Information Reference Signal (CSI-RS) resource set associated with the Channel State Information (CSI) report for channel measurement is equal to K. s When a terminal device processes all streams of all ranks using the same first processing model, the number of units or capabilities corresponding to the processing of the second message can be calculated using the following formula:

[0079] O CPU =K s +RI max O AI Or O CPU =K s +RI max O AI-1 (Formula 1)

[0080] Among them, RI max O AI Or RI max O AI -1 represents the additional processing overhead of AI, O CPU The number of units or capabilities corresponding to the processing of the second message; RI max It is the maximum number of flows supported or a predefined value reported by the terminal device to the network device. AI It is the number of units or capabilities used to process the second message for each flow reported by the terminal device to the network device.

[0081] For example, when a terminal device processes different streams of the same rank using different second processing models, the number of units or capabilities corresponding to the processing of the second message can also be calculated according to the following formula:

[0082]

[0083] in It is the number of units or capabilities corresponding to the processing of the second message occupied by the lth stream reported by the terminal device.

[0084] For example, when a terminal device processes all streams of all ranks using the same first processing model, the number of units or capabilities corresponding to the processing of the second message can be dynamically determined based on the rank indicator reported by the terminal, as shown in the following formula:

[0085] O CPU =K s +RIO AI Or O CPU =K s +RIO AI -1 (Formula 3)

[0086] Among them, RIO AI Or RIO AI -1 represents the additional processing overhead of AI, O CPU To process the number of units or capabilities corresponding to the second message, RI is the number of flows reported by the terminal device in the first part of the second message.

[0087] For example, when a terminal device processes different streams of the same rank using different second processing models, the number of units or capabilities corresponding to the processing of the second message can also be calculated according to the following formula:

[0088]

[0089] in or Additional processing overhead for AI.

[0090] Furthermore, the units or capabilities required for processing the second message are determined based on one or more of the following: resources used for channel measurement, the rank supported by the terminal device, the rank of the second information, and the processing units or capabilities required by the terminal device to process at least one rank.

[0091] When a terminal device processes all ranks using the same third processing model, or when a terminal device processes different ranks using different fourth processing models, the unit or capability corresponding to the processing of the second message can be determined by referring to the following method.

[0092] For example, the number of resources in the CSI-RS resource set used for channel measurements is equal to K. s When the terminal device processes all ranks using the same third processing model, the number of units or capabilities corresponding to the processing of the second message can also be calculated according to the following formula:

[0093] O CPU =K s +O AI Or O CPU =K s +O AI -1 (Formula 5)

[0094] Among them, O AI Or O AI -1 represents the additional processing overhead of AI, O AI The number of units or capabilities required to process the second message reported by the terminal device.

[0095] For example, when the terminal device processes different ranks using different fourth processing models, the number of units or capabilities corresponding to the processing of the second message can also be calculated according to the following formula:

[0096]

[0097] Among them is, or For the additional overhead of AI, The maximum value among the various RI values ​​reported by the terminal device to the network device for processing the second message corresponding to the unit or capability.

[0098] Furthermore, the number of units or capabilities corresponding to the processing of the second message can be dynamically determined based on the rank indicator RI reported by the terminal. Specifically, when the terminal device processes different ranks using different fourth processing models, the number of units or capabilities corresponding to the processing of the second message can be calculated according to the following formula:

[0099]

[0100] in, or For the additional overhead of AI, It is the number of units or capabilities that the terminal device reports to the network device for processing the second message when RI=v. RI is the number of flows reported by the terminal device in the first part of the second message.

[0101] The first, second, third, and fourth processing models mentioned above are mathematical models based on the number of units or capabilities corresponding to the second message calculated by AI.

[0102] For multi-stream CSI reporting scenarios, the unit or capability corresponding to the processing of the second message is determined based on the maximum number of streams supported by the terminal device or the reported RI. AI processing overhead and various processing models are introduced into the method for calculating the unit or capability corresponding to the processing of the second message. This ensures that the standard provides a reasonable measurement of the terminal device's use of AI to process the unit or capability corresponding to the processing of the second message, and effectively guarantees the efficient use of resources for processing the unit or capability corresponding to the processing of the second message under the condition of limited terminal device resources.

[0103] Furthermore, the above information transmission method also includes: sending a fourth message, the fourth message indicating one or more of the methods for determining the units or capabilities required by the terminal device to process the second message.

[0104] Specifically, the fourth message is sent by the terminal device to the network device, instructing the network device how to determine the necessary units or capabilities to process the second message based on different parameters (such as channel measurement resources, the flow of the second information, the terminal device's processing units or capabilities for at least one rank, the rank of the second information, and the terminal device's processing units or capabilities for at least one rank). This helps the network device better understand the terminal device's processing capabilities, thereby making more appropriate scheduling and resource allocation decisions.

[0105] Here, the fourth message can be a Channel State Information Report (CSI) or a Media Access Control-Control Element (MAC) CE. By sending the fourth message to the network device, the different processing models it supports can be dynamically informed to the network device. For example, the fourth message can be reported to the network device when the terminal device initially communicates with the network device, or it can be reported to the network device subsequently after the terminal device has communicated with the network device.

[0106] In summary, according to the technical solution provided in this disclosure, by sending a fourth message from the terminal device to the network device, the network device can more accurately understand the processing capabilities of the terminal device, thereby making more reasonable scheduling and resource allocation decisions. This helps reduce resource waste and improve the overall efficiency of the system. Furthermore, since the fourth message can dynamically update the processing capabilities of the terminal device, it can more flexibly adapt to various communication environments and needs.

[0107] Figure 3 This is a schematic flowchart illustrating an information transmission method according to an embodiment of the present disclosure.

[0108] like Figure 3 As shown, an information transmission method according to an embodiment of this disclosure can be executed by a network device, and the method specifically includes the following steps.

[0109] Step S301: Receive a first message, the first message being used to indicate the payload-related information occupied by the third information carried in the second message, which is supported by the terminal device; or,

[0110] Receive a second message, which carries payload-related information for the third information; or,

[0111] Send a fifth message, which is used to instruct the terminal device to send the payload-related information of the third information carried in the second message.

[0112] Specifically, the second message can be channel state information, used to help network devices understand channel conditions. The third information can include, but is not limited to, one or more of channel information, precoding information, and precoding matrix information. The aforementioned payload-related information can include, but is not limited to, the payload range occupied by at least one level of third information supported by the terminal device, the maximum and / or minimum value of the payload occupied by at least one level of third information supported by the terminal device, the payload range occupied by at least one rank of third information supported by the terminal device, the maximum and / or minimum value of the payload occupied by at least one rank of third information supported by the terminal device, the payload range occupied by the third information carried in the second message, and the maximum and / or minimum value of the payload occupied by the third information carried in the second message. Here, "stream" refers to a data stream (or layer), and one data stream typically corresponds to transmission on a spatial sub-channel. "Rank" refers to the rank of the channel matrix, which determines the number of independent data streams (or layers) that can be transmitted simultaneously.

[0113] In one embodiment of this disclosure, a first message is sent by a terminal device to a network device, indicating to the network device the payload-related information occupied by the third information carried in a second message that the terminal device supports sending to the network device. The network device parses and identifies the received first message, enabling it to understand the terminal's capabilities in advance and thus optimize subsequent processing. Here, the first message may include, but is not limited to, notification messages, indication messages, etc. For example, the network device can know the payload-related information occupied by the third information (e.g., channel information, precoding information, precoding matrix information, etc.) carried by the channel state information supported by the terminal device by receiving the first message.

[0114] In one embodiment of this disclosure, the terminal device can send a second message (such as channel state information) to the network device so that the network device can parse and identify the second message after receiving it, thereby enabling the network device to know the payload-related information occupied by the third information (e.g., channel information, precoding information, precoding matrix information, etc.) carried in the second message.

[0115] In one embodiment of this disclosure, the fifth message is sent by the network device to the terminal device, instructing the terminal device to send the payload-related information of the third information carried in the second message to the network device. After receiving the fifth message, the terminal device can parse and identify it, thereby enabling the terminal device to know the payload-related information of the third information, and thus prepare and send data according to the instructions of the network device.

[0116] In summary, according to the technical solution provided in this disclosure, when a network device receives a first message sent by a terminal device, it can know the payload-related information occupied by the third information sent in the second message supported by the terminal device. This approach enables the network device to optimize the processing flow based on the capability information reported by the terminal device. By receiving the payload-related information carried in the second message, the network device can know the payload-related information supported by the terminal device. By sending a fifth message to the terminal device, the network device can instruct the terminal device to provide payload-related information, which helps to enhance the control capabilities of the network device.

[0117] Furthermore, the second message comprises a first part and a second part, wherein the first part of the second message comprises one or more of the following:

[0118] The rank indicator of the second information, the payload-related information occupied by at least the first-order third information of the second information, and the payload-related information occupied by the third information carried by the second message.

[0119] In embodiments of this disclosure, the second message (such as CSI) may include a first part and a second part. The first part may include, but is not limited to, one or more of the following: a rank indicator of the second information, payload-related information occupied by at least one first-order third information of the second information, and payload-related information occupied by the third information carried in the second message. Thus, by sending or indicating a second message containing the aforementioned information to the network device, the terminal device can provide the network device with detailed information about its current channel state and capabilities. The network device can parse and identify the second message, and thereby, through the rank indicator, the network device can quickly understand the number of data streams that the terminal device can support under the current channel conditions, which helps the network device to quickly allocate and schedule resources, select the most suitable transmission strategy, and thus improve communication efficiency. Through the payload-related information occupied by at least one first-order third information of the second information and the payload-related information occupied by the third information carried in the second message, the terminal device provides the network device with direct feedback on the level of detail of the Channel State Information (CSI). Based on this information, the network device can more accurately assess the feedback capabilities and needs of the terminal device, thereby optimizing resource allocation, such as adjusting the coding rate, modulation scheme, or allocating more resources to terminal devices that require higher-precision CSI.

[0120] In summary, according to the technical solutions provided in the embodiments of this disclosure, by including one or more of various information (rank indicator, payload-related information, etc.) in the first part, the network device can be customized according to different communication scenarios and needs. This achieves a comprehensive improvement in communication efficiency, resource allocation, system flexibility, and user experience.

[0121] Furthermore, if the first part of the second message includes payload-related information occupied by the third information carried by the second message, the second part of the second message includes payload-related information occupied by at least the first-order third information carried by the second message.

[0122] Specifically, the network device parses and identifies the second message. Based on the second message, it can determine that, if the first part of the second message includes payload-related information occupied by the third information carried in the second message, the second part includes payload-related information occupied by at least one level of the third information carried in the second message. This allows the network device to gain a more detailed understanding of the terminal device's capabilities and channel status.

[0123] In summary, the first and second parts of the second message complement each other in providing payload-related information. The first part provides payload-related information occupied by the third information carried by the channel state information, while the second part provides more detailed and specific data stream-level payload-related information. This design helps network devices to have a more comprehensive understanding of the channel state and requirements of terminal devices, thereby making more reasonable scheduling and resource allocation decisions.

[0124] Furthermore, the first part of the second message may also include a third parameter, which is used together with other network device configuration parameters to determine the load-related information occupied by the third information (such as PMI) for each flow. This increases the system's flexibility and configuration capabilities. For example, the load-related information / third parameters reported by the terminal device for each flow can be the same or different; when the load / third parameters for each flow are the same, only one load-related information / third parameter can be configured. Thus, based on the rank indicator RI value carried in the second message, the terminal device can determine which flow the reported PMI corresponds to, and then determine the load-related information occupied by the third information (such as PMI) for each flow through the third parameter.

[0125] Furthermore, the first part of the second message may also include a third parameter, which, together with other network device configuration parameters, determines the payload-related information occupied by the third information (such as PMI). The network device can determine, based on the third parameter, the payload-related information occupied by the third information (such as PMI) in the first part of the received second message, and thus determine the payload-related information that the second part needs to occupy.

[0126] Furthermore, the second part of the second message may also include a third parameter, which is used together with other network device configuration parameters to determine the load-related information occupied by each first-order third message (such as PMI).

[0127] Furthermore, the first part of the second message includes at least the third information of at least one stream of the second message.

[0128] Specifically, the network device receives a second message sent from the terminal device, the first part of which carries at least one third stream of information (such as PMI).

[0129] Furthermore, the first part of the second message may also include at least a first-level portion corresponding to the third information and a rank indicator RI. The third information of the remaining streams, or portions of the third information corresponding to other streams, can be reported to the network device through the second part of the second message. The terminal device sends a second message carrying the rank indicator RI to the network device to indicate the maximum number of data streams (or layers) that the network device can use in downlink transmission. Even if only one data stream is currently being transmitted, the value of RI may indicate that the network has the capacity to support more data streams.

[0130] In summary, according to the technical solution provided in the embodiments of this disclosure, in a multi-stream CSI reporting scenario, the first part of the second message includes third information of at least one stream of the second message. Even if the second part of the second message is discarded, it can still be guaranteed that the network device receives at least one stream of third information (such as PMI) based on the received second message. Although the third information of multiple streams (such as PMI) cannot be known, the network device can still perform single-stream scheduling of service channels based on at least one stream of third information (such as PMI).

[0131] Furthermore, the above information transmission method also includes:

[0132] The fifth message is generated based on the first message received from the terminal device.

[0133] Specifically, after the terminal device sends the first message to the network device, the network device can parse and identify the received first message to understand the capabilities supported by the terminal device and the payload-related information it occupies. This allows the network device to generate a fifth message, which instructs the terminal device on the payload-related information occupied by the third information carried in the second message. The network device then sends the generated fifth message to the terminal device. In this way, the terminal device can more accurately report its supported payload-related information in subsequent second messages based on the instructions in the fifth message.

[0134] In summary, generating the fifth message based on the first message received from the terminal device is an important step in the aforementioned information transmission method. It helps to improve communication flexibility, resource allocation efficiency, reduce misunderstandings and errors, and improve overall communication efficiency.

[0135] Furthermore, the method for determining load-related information can refer to the following:

[0136] Method 1, the fifth message indicates the payload-related information occupied by at least one stream or at least one rank of third information supported by the terminal device.

[0137] Specifically, the network device sends a fifth message to the terminal device to indicate the payload-related information occupied by at least one stream or at least one rank of third information supported by the terminal device.

[0138] For example, the network device determines the payload-related information occupied by PMI in the CSI for the terminal device based on the payload-related information occupied by at least one stream or at least one rank of third information supported by the terminal device as indicated by the received fifth message. By instructing the terminal device to report the payload-related information of the channel state information of the streams or ranks it supports, the network device can more accurately understand the capabilities of the terminal device and adjust its transmission strategy and resource allocation scheme accordingly to improve communication efficiency and performance.

[0139] Furthermore, the fifth message also includes a first parameter, which is used to determine the load-related information occupied by at least one first-level third information. The network device can determine the load-related information occupied by each first-level PMI in the terminal device configuration CSI based on the first parameter. For example, the load-related information / first parameter corresponding to each flow can be the same or different; when the load-related information / first parameter corresponding to each flow is the same, only one load-related information / first parameter can be configured.

[0140] For example, if RI = v, the number of bits occupied by the l-th stream is determined to be A. i (l=1,2…,v), then PMI occupies bits

[0141] In particular, when the first parameter corresponding to each flow is the same, K = vA i .

[0142] For example, the network device determines the payload-related information occupied by PMI in CSI for the terminal device based on the payload-related information occupied by at least one rank of third information supported by the terminal device as indicated by the received fifth message.

[0143] Furthermore, the fifth message also includes a first parameter, which is used to determine the payload-related information occupied by third information (such as PMI) of different ranks. When configuring CSI for terminal devices, network devices can determine the payload-related information occupied by PMI based on the first parameter and RI value. For example, the payload-related information / first parameter corresponding to various RIs can be the same or different; when the payload-related information / first parameter corresponding to each flow is the same, only one payload / first parameter can be configured. The above design ensures the flexibility of configuration to adapt to different transmission requirements and channel conditions, while also reducing signaling overhead to a certain extent, and simplifying the process by sharing configuration information when possible.

[0144] For example, when RI = v, the load-related information A = A in the corresponding CSI PMI. v (RI∈[1,RI max]); or when RI∈[i1,i2], the load-related information A=A in the corresponding CSI PMI. v .

[0145] Method 2, the fifth message indicates the first payload-related information occupied by the first-level third information supported by the terminal device, and the second payload-related information occupied by the third information of other streams supported by the terminal device.

[0146] Specifically, the network device configures the payload-related information occupied by the channel state information for the terminal device based on the first payload-related information occupied by the third information of the first first-level flow supported by the terminal device indicated by the received fifth message, and the second payload-related information occupied by the third information of other flows supported by the terminal device.

[0147] For example, the network device configures the load-related information / first parameter of the first flow PMI and configures the second parameter of the remaining flows. The number of load-related information occupied by the remaining flows is determined based on the load-related information / first parameter of the first flow and the second parameter of the remaining flows.

[0148] For example, assuming RI = v, the number of bits occupied by the first stream is determined to be A1, and the second parameter configured for the l-th stream is α. i (l=2,…,v), then the calculation method for the PMI bit occupancy K is as follows:

[0149]

[0150] For example, when Rank ≤ 4, the network device configures the load-related information / first parameter of the first flow PMI and configures the second parameter of other flows. The number of load-related information occupied by other flow groups is determined based on the load-related information / first parameter of the first flow and the second parameter of other flow groups.

[0151] Method 3, the fifth message indicates the first set of payload-related information occupied by the third information of the first set of streams supported by the terminal device, and the second set of payload-related information occupied by the third information of other sets of streams supported by the terminal device.

[0152] Specifically, the network device determines the load-related information occupied by PMI in CSI for the terminal device based on the first set of load-related information occupied by the third information of the first set of flows supported by the terminal device and the second set of load-related information occupied by the third information of other sets of flows supported by the terminal device, according to the fifth message.

[0153] For example, when Rank≤4, the network device configures the load-related information / first parameter of the first group of flow PMI and configures the second parameter of other groups of flow. The number of load-related information occupied by other groups of flow is determined based on the load-related information / first parameter of the first group of flow and the second parameter of other groups of flow.

[0154] For example, when Rank > 4, the first and second flows are configured with load-related information / first parameter and have the same value (or shared load / first parameter), the third and fourth flows are configured with second parameter and have the same value, the fifth and sixth flows are configured with second parameter and have the same value, and the seventh and eighth flows are configured with second parameter and have the same value.

[0155] For example, the CSI reported by the terminal device includes RI. Assuming RI = v, one method for calculating the PMI bit occupancy K is as follows:

[0156] i. Based on method 1 and the second message described above, including the first and second parts, determine the number of bits occupied by the l-th stream as A. i (l=1,2…,v), then

[0157] Furthermore, specifically, when the first / third parameter corresponding to each flow is the same, K = vA i .

[0158] ii. Based on methods 2 and 3, determine the number of bits occupied by the first stream as A1, and the second parameter configured for the first stream as α. i (l=2,…,v), then

[0159] Furthermore, the above information transmission method also includes:

[0160] Receive a fourth message, which indicates that the terminal device supports one or more of the methods for determining the units or capabilities required to process the second message.

[0161] Specifically, the fourth message is sent by the terminal device to the network device, instructing the network device how to determine the necessary units or capabilities to process the second message based on different parameters (such as channel measurement resources, the flow of the second information, the terminal device's processing units or capabilities for at least one rank, the rank of the second information, and the terminal device's processing units or capabilities for at least one rank). This helps the network device better understand the terminal device's processing capabilities, thereby making more appropriate scheduling and resource allocation decisions.

[0162] Here, the fourth message can be a Channel State Information Report (CSI) or a Media Access Control-Control Element (MAC) CE. By sending the fourth message to the network device, the different processing models it supports can be dynamically informed to the network device. For example, the fourth message can be reported to the network device when the terminal device initially communicates with the network device, or it can be reported to the network device subsequently after the terminal device has communicated with the network device.

[0163] Furthermore, the above information transmission method further includes: determining the unit or capability corresponding to processing the second message based on at least one or more of the following: resources for channel measurement, the stream of the second information, the terminal device for at least a first-order processing unit or capability, the rank of the second information, and the terminal device for at least a rank processing unit or capability.

[0164] Specifically, the terminal device may use artificial intelligence (AI) to calculate the unit or capability corresponding to the second message based on one or more of the following: channel measurement resources, the flow of the second information, the terminal device's processing unit or capability for at least one first-order, the rank of the second information, and the terminal device's processing unit or capability for at least one rank.

[0165] Furthermore, the unit or capability corresponding to processing the second message is determined based on one or more of the resources used for channel measurement, the maximum number of streams supported by the terminal device, and the processing unit or capability required by the terminal device to process at least one stream.

[0166] When a terminal device processes all streams of all ranks using the same first processing model, or when a terminal device processes different streams of the same rank using different second processing models, the unit or capability corresponding to the processing of the second message can be determined by referring to the following method.

[0167] For example, suppose the number of resources in the Channel State Information Reference Signal (CSI-RS) resource set associated with the Channel State Information (CSI) report for channel measurement is equal to K. s When a terminal device processes all streams of all ranks using the same first processing model, the number of units or capabilities corresponding to the processing of the second message can be calculated using the following formula:

[0168] O CPU =K s +RI Max O AI Or O CPU =K s +RI max O AI -1 (Formula 1)

[0169] Among them, RI max O AI Or RI max O AI -1 represents the additional processing overhead of AI, O CPU The number of units or capabilities corresponding to the processing of the second message; RI max It is the maximum number of flows supported or a predefined value reported by the terminal device to the network device. AI It is the number of units or capabilities used to process the second message for each flow reported by the terminal device to the network device.

[0170] For example, when a terminal device processes different streams of the same rank using different second processing models, the number of units or capabilities corresponding to the processing of the second message can also be calculated according to the following formula:

[0171]

[0172] in It is the number of units or capabilities corresponding to the processing of the second message occupied by the lth stream reported by the terminal device.

[0173] For example, when a terminal device processes all streams of all ranks using the same first processing model, the number of units or capabilities corresponding to the processing of the second message can be dynamically determined based on the rank indicator reported by the terminal, as shown in the following formula:

[0174] O CPU =K s +RIO AI Or O CPU =K s +RIO AI -1 (Formula 3)

[0175] Among them, RIO AI Or RIO AI -1 represents the additional processing overhead of AI, O CPU To process the number of units or capabilities corresponding to the second message, RI is the number of flows reported by the terminal device in the first part of the second message.

[0176] For example, when a terminal device processes different streams of the same rank using different second processing models, the number of units or capabilities corresponding to the processing of the second message can also be calculated according to the following formula:

[0177]

[0178] in or Additional processing overhead for AI.

[0179] A method for further determining the units or capabilities required to process the second message includes:

[0180] The units or capabilities required to process the second message are determined based on one or more of the following: resources used for channel measurement, the rank supported by the terminal device, the rank of the second message, and the processing units or capabilities required by the terminal device to process at least one rank.

[0181] Specifically, the units or capabilities required to process the second message can be determined based on at least one or more of the following: resources used for channel measurement, the rank supported by the terminal device, the rank of the second message, and the processing units or capabilities required by the terminal device to process at least one rank.

[0182] When a terminal device processes all ranks using the same third processing model, or when a terminal device processes different ranks using different fourth processing models, the unit or capability corresponding to the processing of the second message can be determined by referring to the following method.

[0183] For example, the number of resources in the CSI-RS resource set used for channel measurements is equal to K. s When the terminal device processes all ranks using the same third processing model, the number of units or capabilities corresponding to the processing of the second message can also be calculated according to the following formula:

[0184] O CPU =K s +O AI Or O CPU =K s +O AI -1 (Formula 5)

[0185] Among them, O AI Or O AI -1 represents the additional processing overhead of AI, O AI The number of units or capabilities required to process the second message reported by the terminal device.

[0186] For example, when the terminal device processes different ranks using different fourth processing models, the number of units or capabilities corresponding to the processing of the second message can also be calculated according to the following formula:

[0187]

[0188] Among them is, or For the additional overhead of AI, The maximum value among the various RI values ​​reported by the terminal device to the network device for processing the second message corresponding to the unit or capability.

[0189] Furthermore, the number of units or capabilities corresponding to the processing of the second message can be dynamically determined based on the RI reported by the terminal. Specifically, when the terminal device processes different ranks using different fourth processing models, the number of units or capabilities corresponding to the processing of the second message can be calculated according to the following formula:

[0190]

[0191] in, or For the additional overhead of AI, It is the number of units or capabilities that the terminal device reports to the network device for processing the second message when RI=v. RI is the number of flows reported by the terminal device in the first part of the second message.

[0192] The first, second, third, and fourth processing models mentioned above are mathematical models based on the number of units or capabilities corresponding to the second message calculated by AI.

[0193] For multi-stream CSI reporting scenarios, the method of determining the number of units or capabilities corresponding to the second message to be processed based on the maximum number of streams supported by the terminal device or the rank indicator of the report introduces AI processing overhead and various processing models, which can reasonably measure the terminal device and effectively ensure the efficient utilization of resources when the terminal device has limited resources to process the units or capabilities corresponding to the second message.

[0194] In summary, according to the technical solution provided in this disclosure, by sending a fourth message from the terminal device to the network device, the network device can more accurately understand the processing capabilities of the terminal device, thereby making more reasonable scheduling and resource allocation decisions. This helps reduce resource waste and improve the overall efficiency of the system. Furthermore, since the fourth message can dynamically update the processing capabilities of the terminal device, it can more flexibly adapt to various communication environments and needs.

[0195] Furthermore, for multi-stream CSI reporting scenarios, by configuring network devices or reporting load-related information for different stream numbers on terminal devices, the bits occupied by PMI are adapted to the various processing models implemented by the terminal devices and the reported rank indicator RI, thereby improving the bit utilization rate in AI-based CSI.

Figure 6 As shown, a computer-readable storage medium 600 according to an embodiment of the present disclosure stores computer-readable instructions 601 thereon. When the computer-readable instructions 601 are executed by a processor, an information transfer method according to any embodiment of the present disclosure described with reference to the above drawings is performed. The computer-readable storage medium includes, but is not limited to, volatile memory and / or non-volatile memory. Volatile memory may include, for example, random access memory (RAM) and / or cache memory.

[0205] Figure 7 This is a schematic diagram illustrating a computer program product according to an embodiment of the present disclosure. Figure 7 As shown, a computer program product 700 according to an embodiment of this disclosure stores a computer program 701 thereon. When the computer program is executed by a processor, it implements the information transmission method as described in any of the embodiments above. The computer program product includes, but is not limited to, system software, application software, and games. System software is the basic software of a computer, responsible for managing the computer's hardware and applications, including operating systems, device drivers, etc. Application software is software designed to meet specific needs, such as office software, image processing software, etc. Games are software used for entertainment, providing various gaming experiences. In addition, the computer program product may also include embedded software, firmware, etc., for controlling and operating various hardware devices.

[0206] The information transmission method, apparatus, storage medium, and computer program product according to embodiments of this disclosure, described in detail above with reference to the accompanying drawings, involve a terminal device sending a first message to a network device, informing it of the payload-related information occupied by the third information sent in a second message. This approach allows the terminal device to declare its capabilities in advance, helping the network device to prepare or optimize its processing flow ahead of time. The terminal device directly informs the network device of the supported payload-related information by carrying payload-related information in the second message. This eliminates the need to send a separate message to indicate capabilities or configurations, simplifying the interaction process and making data transmission more direct and efficient, especially suitable for scenarios requiring rapid response. By receiving a fifth message, the terminal device can provide payload-related information according to the network device's instructions, enhancing the network device's control. Furthermore, for multi-stream CSI reporting scenarios, by configuring the network device or reporting different numbers of streams with payload-related information, the bits occupied by the PMI can be adapted to the terminal device's various processing model implementations and the reported rank indicator RI, improving the bit utilization rate in AI-based CSI. Furthermore, this disclosure proposes a method for determining load-related information for multi-stream devices, which can significantly improve the utilization rate of uplink control information bits. Furthermore, it proposes a corresponding capability or unit calculation mechanism for processing the second message, ensuring that the standard reasonably measures the terminal device's ability or unit to process the second message using AI, effectively guaranteeing efficient resource utilization even when the terminal device's capability or unit for processing the second message is resource-constrained.
