[0004] Channel State Information (CSI) reporting is an important process in wireless communication, which involves the terminal (such as User Equipment (UE)) reporting the channel state to the base station (such as Evolved Node B (eNodeB) or next Generation Node B (gNB)) so that the base station can optimize the downlink transmission according to the channel state. In the traditional CSI reporting, the load occupied by the precoding matrix indicator (PMI) corresponding to different flow numbers is determined by the base station configuration parameters.

[0044] In order to make the objectives, technical solutions and advantages of the present disclosure clearer, the following will describe the example embodiments according to the present disclosure in detail with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all the embodiments of the present disclosure, and it should be understood that the present disclosure is not limited to the example embodiments described herein.

[0045] FIG. 1 is a schematic diagram illustrating a communication system according to an embodiment of the present disclosure.

[0046] As shown in FIG. 1, the communication system 100 can include a network device 101 and a terminal device 102. The network device 101 can communicate with the terminal device 102 through wireless communication. In the process of 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 Signal and PBCH block (SSB) for the terminal device 102, and then the terminal device measures the CSI-RS or SSB and calculates the required Channel State Information (CSI), and reports the CSI, and the network device will adjust the scheduling according to the reported content and perform the work related to beam management.

[0047] The terminal device can be a user equipment (UE), an access terminal, a subscriber unit, a subscriber station, a mobile station, a mobile, a remote station, a remote terminal, a mobile device, a user terminal, a smart phone, a wireless communication device, a user agent, or a user device. The terminal device can also be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a handheld device having wireless communication function, a computing device, or other processing device connected to a wireless modem, a relay device, a vehicle-mounted device, a wearable device, a terminal in a next-generation communication system such as an NR network, or a terminal in a future evolved Public Land Mobile Network (PLMN), and the like. The network device can be a base station (BS), also referred to as a base station device, which is a device deployed in a wireless access network to provide wireless communication function. For example, in a second-generation mobile communication technology (2G) network, devices providing base station function include a base transceiver station (BTS) and a base station controller (BSC); in a third-generation mobile communication technology (3G) network, devices providing base station function include a NodeB and a radio network controller (RNC); in a fourth-generation mobile communication technology (4G) network, devices providing base station function include an evolved NodeB (eNB); in a wireless local area network (WLAN), devices providing base station function include an access point (AP); in a fifth-generation mobile communication technology (5G) new radio (NR) network, devices providing base station function include a gNB; and in a future new communication system, devices providing base station function include the like. No specific limitation is made to this.

[0048] It can be understood that the forms and quantities of the network device and the terminal device shown in FIG. 1 are only for example and do not constitute a limitation on the embodiments of the present disclosure.

[0049] In the conventional CSI reporting, the PMI occupied by different stream numbers is determined by the base station configuration parameters, and the CPU (Central Processing Unit) number corresponding to different stream numbers is also the same. However, for the CSI compression use case in the multi-stream case, the 3rd Generation Partnership Project (3GPP) has proposed multiple potential model deployment methods, but the CSI load design and CPU calculation method corresponding to different model deployment methods may be different.

[0050] If 4 streams need to be transmitted, the terminal needs to allow 4 times of model inference, and the number of bits occupied by the corresponding PMI is 4 times the number of bits occupied by the PMI corresponding to 1 stream transmission, and the CSI calculation complexity is also 4 times that of 1 stream transmission. However, considering that the load corresponding to different layers may be different when multiple streams are transmitted, to ensure that the bits corresponding to the low layer are relatively more. At the same time, the CPU occupied by this model is also different when the number of streams is different. These all need to enhance the load occupied by CSI and the CPU calculation method.

[0051] Based on the above problems, the present disclosure is proposed.

[0052] FIG. 2 is a flow diagram illustrating an information transmission method according to an embodiment of the present disclosure.

[0053] As shown in FIG. 2, according to an information transmission method according to an embodiment of the present disclosure, the method can be executed by a terminal device, and the method specifically includes the following steps.

[0054] Step 201, a first message is sent, the first message is used to indicate the load related information occupied by the third information carried by a second message supported by a terminal device; or the second message is sent, the second message carries the load related information occupied by the third information; or a fifth message is received, the fifth message is used to indicate the load related information occupied by the third information carried by the second message sent by the terminal device.

[0055] Specifically, the second message can be channel state information, which is used to help the network device to understand the channel condition. The third information can include, but is not limited to, one or more of channel information, precoding information, and precoding matrix information. The above-mentioned payload related information can include, but is not limited to, a payload range occupied by the third information of at least one stream supported by the terminal device, a maximum value and / or a minimum value of the payload occupied by the third information of at least one stream supported by the terminal device, a payload range occupied by the third information of at least one rank supported by the terminal device, a maximum value and / or a minimum value of the payload occupied by the third information of at least one rank supported by the terminal device, a payload range occupied by the third information carried by the second message, a maximum value and / or a minimum value of the payload occupied by the third information carried by the second message. Here, the "stream" refers to a data stream (or layer), and one data stream usually corresponds to a transmission on one spatial subchannel. The "rank" refers to the rank of a channel matrix, which determines the number of independent data streams (or layers) that can be transmitted simultaneously. The rank can also be represented by RI, which is the rank indicator.

[0056] In an embodiment of the present disclosure, the first message is sent by the terminal device to the network device, and is used to indicate to the network device the payload related information occupied by the third information carried by the second message sent to the network device. The terminal device sends the first message to the network device, which helps the network device to understand the terminal's capability in advance, so as to optimize the subsequent processing flow. Here, the first message can include, but is not limited to, a notification message, an indication message, etc. In order to communicate, the terminal device can actively or passively (for example, in response to a request from the terminal side) send an indication message to the second device to indicate the payload related information occupied by the third information (such as channel information, precoding information, and precoding matrix information) carried by the second message sent to the network device. Exemplarily, the terminal device can inform the network device of the payload related information occupied by the third information (such as channel information, precoding information, and precoding matrix information) carried by the channel state information supported by the terminal device by sending the first message.

[0057] In an embodiment of the present disclosure, the terminal device can inform the network device of the payload related information occupied by the third information (such as channel information, precoding information, and precoding matrix information) by sending the second message (such as channel state information) to the network device. Exemplarily, in order to communicate, the terminal device can report the channel state information to the second device to inform the network device of the payload related information occupied by the channel information, the precoding information, and the precoding matrix information. Therefore, the network device can understand the reporting capability of the terminal device and the current channel condition in real time, so as to perform more accurate resource allocation and transmission optimization.

[0058] In an embodiment of the present disclosure, the fifth message is sent by the network device to the terminal device, and is used to indicate the payload related information occupied by the third information carried in the second message sent by the terminal device to the network device. After receiving the fifth message, the terminal device can parse and identify the received fifth message, and can understand the specific requirements of the network device for the CSI report. According to the parsing result, the terminal device determines which payload related information of the third information should be included in the second message sent subsequently.

[0059] Exemplarily, the payload related information range or the maximum value or the minimum value (RI∈[1, RI max ], where RI max is the maximum number of streams supported by the terminal device or a predefined value) corresponding to at least one rank value of the PMI in the supportable CSI.

[0060] In summary, according to the technical scheme provided by the embodiments of the present disclosure, the terminal device sends the first message to the network device to inform the payload related information occupied by the third information sent in the second message. This way allows the terminal device to declare its capability in advance, which helps the network device to prepare or optimize the processing flow in advance. The terminal device directly carries the payload related information in the second message to inform the network device of the payload related information it supports. There is no need to send a separate message to indicate the capability or configuration, which simplifies the interaction process. It makes the data transmission more direct and efficient, and is especially suitable for scenarios that require fast response. The terminal device can provide the payload related information according to the indication of the network device by receiving the fifth message. This way enhances the control of the network device. The above-mentioned configuration of the network device or the report of the terminal device of the payload related information occupied by each flow can ensure that the PMI corresponding to a more important layer occupies a relatively larger number of bits, and ensure the efficient use of uplink control information (UCI) bits.

[0061] Further, the second message includes a first part and a second part, and the first part of the second message includes one or more of the following:

[0062] The rank indicator of the second information, the payload related information occupied by the third information of at least one stream of the second information, and the payload related information occupied by the third information carried in the second message.

[0063] In embodiments of the present disclosure, the second message (e.g., CSI) can include a first part and a second part. The first part can include, but is not limited to, one or more of a rank indicator of the second information, payload-related information occupied by the third information of at least one stream of the second information, and payload-related information occupied by the third information carried by the second message. In this way, the terminal device can provide detailed information about its current channel state and capability to the network device by sending or indicating the second message containing the above information to the network device. This allows the network device to quickly understand the number of data streams that the terminal device can support under the current channel conditions through the rank indicator, and helps the network device to quickly make resource allocation and scheduling decisions and select the most suitable transmission strategy, thereby improving communication efficiency. Through the payload-related information occupied by the third information of at least one stream of the second information and the payload-related information occupied by the third information carried by the second message, the terminal device provides direct feedback to the network device about the detailed level of channel state information (CSI). Based on this information, the network device can more accurately assess the feedback capability and needs of the terminal device, thereby optimizing resource configuration, such as adjusting the coding rate, modulation method, or allocating more resources to terminal devices that require more accurate CSI.

[0064] In summary, according to the technical solutions provided by embodiments of the present disclosure, by having the first part contain one or more of multiple types of information (rank indicator, payload-related information, etc.), the network device can be customized according to different communication scenarios and needs. This achieves comprehensive improvement in communication efficiency, resource configuration, system flexibility, and user experience.

[0065] Further, in the case where the first part of the second message includes the payload-related information occupied by the third information carried by the second message, the second part of the second message includes the payload-related information occupied by the third information of at least one stream carried by the second message.

[0066] Specifically, the terminal device reports to the network device that the first part of the second message includes the payload-related information occupied by the third information carried by the second message by sending the second message to the network device, and reports to the network device that the second part includes the payload-related information occupied by the third information of at least one stream carried by the second message.

[0067] In summary, the first part and the second part of the second message form a complementary relationship in the provision of 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 payload-related information at the data stream level. This design helps the network device to more comprehensively understand the channel state and needs of the terminal device, and thus makes more reasonable scheduling and resource configuration decisions.

[0068] Further, the first part of the second message can further comprise a third parameter, which is used to determine the payload related information occupied by the third information (e.g. PMI) of each stream together with other network device configuration parameters. This increases the flexibility and configuration capability of the system. Exemplarily, the payload related information / third parameter corresponding to each stream reported by the terminal device can be the same or different; when the payload / third parameter corresponding to each stream is the same, only one payload related information / third parameter can be configured. Thus, the terminal device can determine the reported PMI corresponds to several streams according to the rank indicator (RI) value carried by the second message, and further determine the payload related information occupied by the third information (e.g. PMI) of each stream through the third parameter.

[0069] Here, the other network device configuration parameters comprise: CSI reporting bandwidth, CSI-RS port number.

[0070] Further, the first part of the second message can further comprise a third parameter, which is used to determine the payload related information occupied by the third information (e.g. PMI) together with other network device configuration parameters. The network device can determine that the first part of the received second message contains the payload related information occupied by the third information (e.g. PMI) according to the third parameter, and further determine the payload related information required to be occupied by the second part.

[0071] Further, the second part of the second message can further comprise a third parameter, which is used to determine the payload related information occupied by the third information (e.g. PMI) of each stream together with other network device configuration parameters.

[0072] Further, the first part of the second message comprises at least the third information of at least one stream of the second message.

[0073] Specifically, the terminal device sends the second message to the network device, wherein the first part of the second message carries the third information (e.g. PMI) of at least one stream.

[0074] Further, the first part of the second message can further comprise a third information corresponding to at least one stream and a rank indicator (RI). The third information of the remaining streams or the part 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 the second message carrying the rank indicator (RI) to the network device, which can inform the network device of the maximum number of data streams (or layer number) that can be used in the downlink transmission. Even if only one data stream is currently being transmitted, the value of the RI can indicate that the network has the ability to support more data streams.

[0075] In summary, according to the technical scheme provided by the embodiments of the present disclosure, in the CSI reporting scenario for multiple streams, the first part of the second message includes the third information of at least one stream of the second message, so that even if the second part of the second message is discarded, the network device can still receive the third information (such as PMI) of at least one stream according to the received second message. Although the third information (such as PMI) of multiple streams cannot be obtained, the network device can still perform single-stream scheduling of the service channel according to the third information (such as PMI) of at least one stream.

[0076] Further, the above information transmission method further includes: determining a unit or capability for processing the second message based on one or more of the following: a resource for channel measurement, a stream of the second information, a processing unit or capability of the terminal device for at least one stream, a rank of the second information, and a processing unit or capability of the terminal device for at least one rank.

[0077] Specifically, the terminal device can determine the unit or capability for processing the second message based on artificial intelligence (AI) according to one or more of the following: a resource for channel measurement, a stream of the second information, a processing unit or capability of the terminal device for at least one stream, a rank of the second information, and a processing unit or capability of the terminal device for at least one rank.

[0078] Further, the unit or capability for processing the second message is determined based on one or more of the following: a resource for channel measurement, a maximum number of streams supported by the terminal device, and a required processing unit or capability of the terminal device for processing at least one stream.

[0079] In the case where the terminal device processes all streams of all ranks by using the same first processing model and in the case where the terminal device processes different streams of the same rank by using different second processing models, the unit or capability for processing the second message can be determined by referring to the following methods.

[0080] For example, assuming that the number of resources in a channel state information reference signal (CSI-RS) resource set for channel measurement associated with channel state information (CSI) reporting is equal to K s In the case where the terminal device processes all streams of all ranks by using the same first processing model, the number of units or capabilities for processing the second message can be calculated by the following formula:

[0081] O CPU = K s + RI max O AI or O CPU = K s + RI max OAI -1 (Formula 1)

[0082] wherein, RIO max O AI or RIO max O AI -1 is the AI additional processing overhead, O CPU is the number of units or capabilities for processing the second message; RIO max is the maximum number of flows supported by the terminal device and reported to the network device or a predefined value, O AI is the number of units or capabilities for processing the second message occupied by each flow reported by the terminal device to the network device.

[0083] Exemplarily, in the case that the terminal device processes different flows of the same rank by using different second processing models, the number of units or capabilities for processing the second message can also be calculated according to the following formula:

[0084] or

[0085] wherein, RIO is the number of units or capabilities for processing the second message occupied by the lth flow reported by the terminal device.

[0086] Exemplarily, in the case that the terminal device processes all flows of all ranks by using the same first processing model, the number of units or capabilities for processing the second message can be dynamically determined according to the rank indicator reported by the terminal device, and specific reference can be made to the following formula:

[0087] O CPU = K s + RIO AI or O CPU = K s + RIO AI -1 (Formula 3)

[0088] wherein, RIO AI or RIO AI -1 is the AI additional processing overhead, O CPU is the number of units or capabilities for processing the second message, and RIO is the number of flows reported by the terminal device in the first part of the second message.

[0089] Exemplarily, in the case that the terminal device processes different flows of the same rank by using different second processing models, the number of units or capabilities for processing the second message can also be calculated according to the following formula:

[0090] or

[0091] wherein or is the additional processing overhead for AI.

[0092] Further, based on one or more of the resource for channel measurement, the rank supported by the terminal device, the rank of the second information, the required processing units or capabilities of the terminal device for processing at least one rank, the number of units or capabilities required for processing the second message is determined.

[0093] In the case where the terminal device processes all ranks by using the same third processing model, and in the case where the terminal device processes different ranks by using different fourth processing models, the number of units or capabilities corresponding to processing the second message can be determined by referring to the following methods.

[0094] Exemplarily, the number of resources in the CSI-RS resource set for channel measurement is equal to K s In the case where the terminal device processes all ranks by using the same third processing model, the number of units or capabilities corresponding to processing the second message can also be calculated according to the following formula:

[0095] O CPU = K s + O AI or O CPU = K s + O AI - 1 (Formula 5)

[0096] wherein O AI or O AI - 1 is the additional processing overhead for AI, and O AI is the number of units or capabilities required for processing the second message reported by the terminal device.

[0097] Exemplarily, in the case where the terminal device processes different ranks by using different fourth processing models, the number of units or capabilities corresponding to processing the second message can also be calculated according to the following formula:

[0098] or

[0099] wherein is, or is the additional overhead for AI, is the maximum value of the number of units or capabilities corresponding to processing the second message corresponding to various RI values reported by the terminal device to the network device.

[0100] Further, the number of units or capabilities corresponding to the second message can be dynamically determined according to the rank indicator RI reported by the terminal, specifically, in the case that the terminal device processes different ranks by using different fourth processing models, the number of units or capabilities corresponding to the second message can be calculated according to the following formula:

[0101] or

[0102] wherein, or is the additional overhead of AI, is the number of units or capabilities corresponding to the second message reported by the terminal device to the network device when RI=v, and RI is the number of streams reported by the terminal device in the first part of the second message.

[0103] The first processing model, the second processing model, the third processing model, and the fourth processing model are mathematical models for calculating the number of units or capabilities corresponding to the second message based on AI.

[0104] For the CSI reporting scenario of multiple streams, the number of units or capabilities corresponding to the second message is determined based on the maximum number of streams supported by the terminal device or the reported RI, and AI processing overhead and various processing models are introduced in the method for calculating the number of units or capabilities corresponding to the second message, which ensures that the standard reasonably measures the number of units or capabilities corresponding to the second message by using AI, and effectively guarantees the resource efficient utilization of the number of units or capabilities corresponding to the second message in the case of limited terminal device resources.

[0105] Further, the information transmission method further includes: sending a fourth message, the fourth message indicating that the terminal device supports one or more of the determination methods of the units or capabilities required for processing the second message.

[0106] Specifically, the fourth message is sent by the terminal device to the network device, and is used to indicate how the network device determines the units or capabilities required for processing the second message according to different parameters (such as channel measurement resources, streams of the second information, processing units or capabilities of the terminal device for at least one stream, rank of the second information, processing units or capabilities of the terminal device for at least one rank, etc.). This helps the network device better understand the processing capability of the terminal device, so as to make more appropriate scheduling and resource configuration decisions.

[0107] Here, the fourth message can be a channel state information report (CSI report) or a medium access control-control element (MAC CE). By sending the fourth message to the network device, the network device can be dynamically informed of the different processing models supported by the terminal device. Illustratively, the fourth message can be reported to the network device when the terminal device initially communicates with the network device, or can be subsequently reported to the network device after the terminal device communicates with the network device.

[0108] In summary, according to the technical solutions provided by the embodiments of the present disclosure, the network device can more accurately understand the processing capability of the terminal device by sending the fourth message from the terminal device, so as to make more reasonable scheduling and resource allocation decisions. This helps to reduce resource waste and improve the overall efficiency of the system. Further, since the fourth message can dynamically update the processing capability of the terminal device, it can more flexibly adapt to various communication environments and needs.

[0109] FIG. 3 is a flow diagram illustrating an information transmission method according to an embodiment of the present disclosure.

[0110] As shown in FIG. 3, according to an information transmission method according to an embodiment of the present disclosure, the method can be performed by a network device, and specifically includes the following steps.

[0111] Step S301, receiving a first message, the first message being used to indicate the payload related information occupied by the third information carried by a second message and supported by a terminal device; or,

[0112] receiving a second message, the second message carrying the payload related information occupied by the third information; or,

[0113] sending a fifth message, the fifth message being used to indicate the payload related information occupied by the third information carried by the second message and sent by the terminal device.

[0114] Specifically, the second message can be channel state information, which is used to help the network device to understand the channel condition. The third information can include, but is not limited to, one or more of channel information, precoding information, and precoding matrix information. The above-mentioned payload related information can include, but is not limited to, a payload range occupied by the third information of at least one stream supported by the terminal device, a maximum value and / or a minimum value of the payload occupied by the third information of at least one stream supported by the terminal device, a payload range occupied by the third information of at least one rank supported by the terminal device, a maximum value and / or a minimum value of the payload occupied by the third information of at least one rank supported by the terminal device, a payload range occupied by the third information carried by the second message, a maximum value and / or a minimum value of the payload occupied by the third information carried by the second message. Here, the "stream" refers to a data stream (or layer), and one data stream usually corresponds to a transmission on one spatial subchannel. The "rank" refers to the rank of a channel matrix, which determines the number of independent data streams (or layers) that can be transmitted simultaneously.

[0115] In an embodiment of the present disclosure, the first message is sent by the terminal device to the network device, and is used to indicate to the network device the payload related information occupied by the third information carried by the second message sent by the network device. The network device parses and identifies the received first message, and can know the capability of the terminal in advance, so as to optimize the subsequent processing flow. Here, the first message can include, but is not limited to, a notification message, an indication message, etc. Exemplarily, the network device can know the payload related information occupied by the third information (such as channel information, precoding information, and precoding matrix information) carried by the channel state information supported by the terminal device side through receiving the first message.

[0116] In an embodiment of the present disclosure, the terminal device can send the 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 the second message, and thus the network device can know the payload related information occupied by the third information (such as channel information, precoding information, and precoding matrix information) carried by the second message.

[0117] In an embodiment of the present disclosure, the fifth message is sent by the network device to the terminal device, and is used to indicate the payload related information occupied by the third information carried by the second message sent by the terminal device to the network device. After receiving the fifth message, the terminal device can parse and identify the received fifth message, and thus the terminal device can know the payload related information occupied by the third information, and can prepare and send data according to the indication of the network device.

[0118] In summary, according to the technical scheme provided by the embodiments of the present disclosure, the network device can know the payload related information supported by the terminal device and occupied by the third information sent in the second message after receiving the first message sent by the terminal device. In this way, the network device can optimize the processing flow according to the capability information reported by the terminal device. The network device can know the payload related information supported by the terminal device by receiving the second message carrying the payload related information. The network device can instruct the terminal device to provide the payload related information by sending the fifth message to the terminal device, which helps to enhance the control of the network device.

[0119] Further, the second message includes a first part and a second part, and the first part of the second message includes one or more of the following:

[0120] The rank indicator of the second information, the payload related information occupied by the third information of at least one stream of the second information, and the payload related information occupied by the third information carried by the second message.

[0121] In the embodiments of the present disclosure, the second message (such as CSI) can include a first part and a second part. The first part can include one or more of the following, but is not limited to: the rank indicator of the second information, the payload related information occupied by the third information of at least one stream of the second information, and the payload related information occupied by the third information carried by the second message. In this way, the terminal device can provide detailed information about its current channel state and capability to the network device by sending or indicating the second message containing the above information to the network device. The network device can analyze and identify the second message, and then the network device can quickly understand the number of data streams that the terminal device can support under the current channel condition through the rank indicator, which helps the network device to quickly allocate resources and schedule and select the most suitable transmission strategy, thereby improving the communication efficiency. Through the payload related information occupied by the third information of at least one stream of the second information and the payload related information occupied by the third information carried by the second message, the terminal device provides direct feedback on the detailed level of channel state information (CSI) to the network device. Based on this information, the network device can more accurately evaluate the feedback capability and demand of the terminal device, thereby optimizing resource configuration, such as adjusting the coding rate, modulation mode, or allocating more resources to the terminal device that needs higher precision CSI.

[0122] In summary, according to the technical scheme provided by the embodiments of the present disclosure, by making the first part contain one or more of the various information (rank indicator, payload related information, etc.), the network device can be customized according to different communication scenarios and needs. This realizes the comprehensive improvement of communication efficiency, resource configuration, system flexibility, and user experience.

[0123] Further, in the case that the first part of the second message includes the payload related information occupied by the third information carried by the second message, the second part of the second message includes the payload related information occupied by the third information of at least one stream carried by the second message.

[0124] Specifically, the network device parses and identifies the second message, and can know, according to the second message, that in the case that the first part of the second message includes the payload related information occupied by the third information carried by the second message, the second part includes the payload related information occupied by the third information of at least one stream carried by the second message. Thus, it is beneficial for the network device to know the capability and channel state of the terminal device in more detail.

[0125] In summary, the first part and the second part of the second message form a complementary relationship in the provision of payload related information. The first part provides the payload related information occupied by the third information carried by the channel state information, and the second part provides more detailed and specific payload related information at the data stream level. This design helps the network device to more comprehensively understand the channel state and needs of the terminal device, so as to make more reasonable scheduling and resource configuration decisions.

[0126] Further, the first part of the second message can further include a third parameter, which is used to determine, together with other network device configuration parameters, the payload related information occupied by the third information (such as PMI) of each stream. This increases the flexibility and configuration capability of the system. Exemplarily, the payload related information / third parameter corresponding to each stream reported by the terminal device can be the same or different; when the payload / third parameter corresponding to each stream is the same, only one payload related information / third parameter can be configured. Thus, the terminal device can determine, according to the rank indicator (RI) value carried by the second message, that the reported PMI corresponds to several streams, and further determine, through the third parameter, the payload related information occupied by the third information (such as PMI) of each stream.

[0127] Further, the first part of the second message can further include a third parameter, which is used to determine, together with other network device configuration parameters, the payload related information occupied by the third information (such as PMI). The network device can determine, according to the third parameter, that the received first part of the second message contains the payload related information occupied by the third information (such as PMI), and further determine the payload related information required by the second part.

[0128] Further, the second part of the second message can further include a third parameter, which is used to determine, together with other network device configuration parameters, the payload related information occupied by the third information (such as PMI) of each stream.

[0129] Further, the first part of the second message includes at least the third information of at least one stream of the second message.

[0130] Specifically, the network device receives a second message sent from the terminal device, and a first part of the second message carries third information (such as PMI) of at least one stream.

[0131] Further, the first part of the second message can further include a rank indicator RI and a part of the third information corresponding to at least one stream. The third information of the remaining streams or the part of the third information corresponding to other streams can be reported to the network device through a second part of the second message. The terminal device sends the second message carrying the rank indicator RI to the network device, so that the network device can use the maximum number of data streams (or layers) in the downlink transmission. Even if only one data stream is currently being transmitted, the value of the RI can indicate that the network has the ability to support more data streams.

[0132] In summary, according to the technical scheme provided by the embodiments of the present disclosure, in the CSI reporting scenario for multiple streams, the first part of the second message includes the third information (such as PMI) of at least one stream of the second message, so that even if the second part of the second message is discarded, the network device can receive the third information (such as PMI) of at least one stream according to the received second message. Although the third information (such as PMI) of multiple streams cannot be obtained, the network device can also perform single-stream scheduling of the service channel according to the third information (such as PMI) of at least one stream.

[0133] Further, the above information transmission method further includes:

[0134] generating a fifth message based on the first message received from the terminal device.

[0135] 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 identify and understand the supported capabilities and occupied load-related information of the terminal device, and then generate a fifth message, which is used to indicate the load-related information occupied by the third information carried by the terminal device in the second message. The network device sends the generated fifth message to the terminal device. In this way, the terminal device can more accurately report the supported load-related information in the subsequent second message according to the indication of the fifth message.

[0136] In summary, generating the fifth message based on the first message received from the terminal device is an important step in the above information transmission method, which helps to improve the flexibility of communication, the efficiency of resource allocation, reduce misunderstanding and errors, and improve the overall communication efficiency.

[0137] Further, the determination method of the load-related information can refer to the following method:

[0138] The method 1, the fifth message indicates the payload related information occupied by the third information of at least one stream or at least one rank supported by the terminal device.

[0139] Specifically, the network device indicates the payload related information occupied by the third information of at least one stream or at least one rank supported by the terminal device by sending the fifth message to the terminal device.

[0140] Exemplarily, the network device determines the payload related information occupied by the PMI in the CSI for the terminal device according to the payload related information occupied by the third information of at least one stream or at least one rank supported by the terminal device indicated by the received fifth message. By indicating the payload related information of the channel state information reported by the terminal device for the stream or rank supported by the terminal device, the network device can more accurately understand the capability of the terminal device, and accordingly adjust the transmission strategy and resource allocation scheme to improve the communication efficiency and performance.

[0141] Further, the fifth message further comprises a first parameter, and the first parameter is used to determine the payload related information occupied by the third information of at least one stream. The network device can determine the payload related information occupied by the PMI of each stream in the CSI configured by the terminal device according to the first parameter. Exemplarily, the payload related information / first parameter corresponding to each stream can be the same or different; when the payload related information / first parameter corresponding to each stream is the same, only one payload related information / first parameter can be configured.

[0142] For example, assuming that RI=v, the number of bits occupied by the lth stream is determined as A i (l=1, 2…, v), and the number of bits occupied by the PMI is determined as K=A(v-1)

[0143] In particular, when the first parameters corresponding to each stream are the same, K=vA i .

[0144] Exemplarily, the network device determines the payload related information occupied by the PMI in the CSI for the terminal device according to the payload related information occupied by the third information of at least one rank supported by the terminal device indicated by the received fifth message.

[0145] Further, the fifth message further comprises a first parameter, the first parameter being used to determine the payload related information occupied by the third information (e.g. PMI) of different ranks. When the network device configures the CSI for the terminal device, the payload related information occupied by the PMI can be determined according to the first parameter and the RI value. Exemplarily, 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 various streams is the same, only one payload / first parameter can be configured. The above design not only ensures the flexibility of configuration to adapt to different transmission requirements and channel conditions, but also reduces the signaling overhead to some extent, and simplifies the process by sharing the configuration information when possible.

[0146] For example, when RI=v, the payload related information A corresponding to the PMI in the corresponding CSI is A v (RI∈[1,RI max ); or when RI∈[i1,i2], the payload related information A corresponding to the PMI in the corresponding CSI is A v .

[0147] Method 2: The fifth message indicates the first payload related information occupied by the third information of the first stream supported by the terminal device, and the second payload related information occupied by the third information of other streams supported by the terminal device.

[0148] Specifically, the network device configures the payload related information occupied by the channel state information according to the first payload related information occupied by the third information of the first stream supported by the terminal device and the second payload related information occupied by the third information of other streams supported by the terminal device, which is indicated by the received fifth message.

[0149] Exemplarily, the network device configures the payload related information / first parameter of the PMI of the first stream, and configures the second parameter of the remaining streams, and the number of payload related information occupied by the remaining streams is determined according to the payload related information / first parameter of the first stream and the second parameter of the remaining streams.

[0150] For example, assuming that RI=v, the number of bits occupied by the first stream is determined to be A1, and the second parameter of the lth stream is α i (l=2,…,v), then the calculation method of the number of bits K occupied by the PMI is:

[0151] For example, when the rank Rank≤4, the network device configures the payload related information / first parameter of the PMI of the first stream, and configures the second parameter of the other streams, and the number of payload related information occupied by the other groups of streams is determined according to the payload related information / first parameter of the first stream and the second parameter of the other groups of streams.

[0152] 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.

[0153] Specifically, the network device determines the payload related information occupied by the PMI in the CSI for the terminal device according to the first set of payload related information occupied by the third information of the first set of streams supported by the terminal device indicated by the fifth message, and the second set of payload related information occupied by the third information of other sets of streams supported by the terminal device.

[0154] Exemplarily, when the rank Rank≤4, the network device configures the payload related information / first parameter of the first set of streams PMI, and configures the second parameter of other sets of streams, and the number of payload related information occupied by the other sets of streams is determined according to the payload related information / first parameter of the first set of streams and the second parameter of the other sets of streams.

[0155] Exemplarily, when Rank>4, the first and second streams are both configured with payload related information / first parameter, and the values are the same (or called shared payload / first parameter), the third and fourth streams are both configured with the second parameter, and the values are the same, the fifth and sixth streams are both configured with the second parameter, and the values are the same, and the seventh and eighth streams are both configured with the second parameter, and the values are the same.

[0156] For another example: the CSI reported by the terminal device contains RI, assuming that RI=v, and one method of calculating the number of bits K occupied by PMI is as follows:

[0157] i. According to method 1 and the second message including the first part and the second part described above, the number of bits occupied by the lth stream is A i (l=1, 2…, v), then

[0158] Further, in particular, when the first parameter / third parameter corresponding to each stream is the same, K=vA i .

[0159] ii. According to method 2 and method 3, the number of bits occupied by the first stream is A1, and the second parameter configured for the lth stream is α i (l=2,…,v), then

[0160] Further, the above information transmission method further comprises:

[0161] Receiving a fourth message, the fourth message indicating one or more of the determination methods of the unit or capability required by the terminal device to support processing the second message.

[0162] Specifically, the fourth message is sent by the terminal device to the network device, and is used to instruct the network device to determine the unit or capability required for processing the second message according to different parameters (such as a resource for channel measurement, a flow of the second information, a processing unit or capability of the terminal device for at least one flow, a rank of the second information, a processing unit or capability of the terminal device for at least one rank, and the like). This helps the network device to better understand the processing capability of the terminal device, so as to make more appropriate scheduling and resource configuration decisions.

[0163] Here, the fourth message can be a channel state information report (CSI report) or a medium access control-control element (MAC CE). By sending the fourth message to the network device, the network device can be dynamically informed of different processing models supported by the terminal device. Exemplarily, the fourth message can be reported to the network device when the terminal device initially communicates with the network device, or can be subsequently reported to the network device after the terminal device communicates with the network device.

[0164] Further, the above information transmission method further includes: determining the unit or capability corresponding to processing the second message based on one or more of the following: a resource for channel measurement, a flow of the second information, a processing unit or capability of the terminal device for at least one flow, a rank of the second information, and a processing unit or capability of the terminal device for at least one rank.

[0165] Specifically, the terminal device can use artificial intelligence (AI) to calculate the unit or capability corresponding to processing the second message according to one or more of the following: a resource for channel measurement, a flow of the second information, a processing unit or capability of the terminal device for at least one flow, a rank of the second information, and a processing unit or capability of the terminal device for at least one rank.

[0166] Further, the unit or capability corresponding to processing the second message is determined based on one or more of the following: a resource for channel measurement, a maximum number of flows supported by the terminal device, and a processing unit or capability required by the terminal device for processing at least one flow.

[0167] In the case where the terminal device processes all flows of all ranks using the same first processing model and in the case where the terminal device processes different flows of the same rank using different second processing models, the unit or capability corresponding to processing the second message can be determined by referring to the following methods.

[0168] Exemplarily, assuming that the number of resources in a channel state information reference signal (CSI-RS) resource set associated with a channel state information (CSI) report is equal to K sIn the case that the terminal device processes all the streams of all ranks by using the same first processing model, the number of units or capabilities corresponding to processing the second message can be calculated by the following formula:

[0169] O CPU =K s +RI max O AI or O CPU =K s +RI max O AI -1 (Formula 1)

[0170] wherein, RI max O AI or RI max O AI -1 is the AI additional processing overhead, O CPU is the number of units or capabilities corresponding to processing the second message; RI max is the maximum number of streams supported by the terminal device and reported to the network device or a predefined value, and O AI is the number of units or capabilities occupied by each stream of the terminal device and reported to the network device.

[0171] Exemplarily, in the case that the terminal device processes different streams of the same rank by using different second processing models, the number of units or capabilities corresponding to processing the second message can also be calculated according to the following formula:

[0172] or

[0173] wherein, O is the number of units or capabilities occupied by the lth stream and reported by the terminal device and corresponding to processing the second message.

[0174] Exemplarily, in the case that the terminal device processes all the streams of all ranks by using the same first processing model, the number of units or capabilities corresponding to processing the second message can be dynamically determined according to the rank indicator reported by the terminal, and specific reference can be made to the following formula:

[0175] O IPU =K s +RIO AI or O CPU =K s +RIO AI -1 (Formula 3)

[0176] wherein, RIO AI or RIO AI -1 is the AI additional processing overhead, O CPUThe number of units or capabilities for processing the second message is determined according to the following formula:

[0177] For example, in the case where the terminal device processes different streams of the same rank by using different second processing models, the number of units or capabilities for processing the second message can also be calculated according to the following formula:

[0178] Or

[0179] Wherein Or is the AI additional processing overhead.

[0180] Further, the method for determining the units or capabilities required for processing the second message comprises:

[0181] The units or capabilities required for processing the second message are determined based on one or more of the following: the resources for channel measurement, the ranks supported by the terminal device, the rank of the second information, and the required processing units or capabilities of the terminal device for processing at least one rank.

[0182] Specifically, the units or capabilities required for processing the second message can be determined based on one or more of the following: the resources for channel measurement, the ranks supported by the terminal device, the rank of the second information, and the required processing units or capabilities of the terminal device for processing at least one rank.

[0183] In the case where the terminal device processes all ranks by using the same third processing model, and in the case where the terminal device processes different ranks by using different fourth processing models, the units or capabilities for processing the second message can be determined by referring to the following method.

[0184] For example, the number of resources in the CSI-RS resource set for channel measurement is equal to K s In the case where the terminal device processes all ranks by using the same third processing model, the number of units or capabilities for processing the second message can also be calculated according to the following formula:

[0185] O CPU = K s + O AI Or O CPU = K s + O AI -1 (Formula 5)

[0186] Wherein, O AI Or O AI -1 is the AI additional processing overhead, O AIThe number of units or capabilities corresponding to the processing of the second message that needs to be occupied by the terminal device.

[0187] Exemplarily, in the case that the terminal device processes different ranks by 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:

[0188] Or

[0189] Wherein, Or is the additional overhead of AI, is the maximum value in the number of units or capabilities corresponding to the processing of the second message corresponding to the values of various RIs reported by the terminal device to the network device.

[0190] Further, the number of units or capabilities corresponding to the processing of the second message can be dynamically determined according to the RI reported by the terminal, specifically, in the case that the terminal device processes different ranks by 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:

[0191] Or

[0192] Wherein, Or is the additional overhead of AI, is the number of units or capabilities corresponding to the processing of the second message reported by the terminal device to the network device when RI=v, and RI is the number of streams reported by the terminal device in the first part of the second message.

[0193] The first processing model, the second processing model, the third processing model and the fourth processing model are mathematical models for calculating the number of units or capabilities corresponding to the processing of the second message based on AI.

[0194] In the method for determining the number of units or capabilities corresponding to the processing of the second message based on the maximum number of streams supported by the terminal device or the rank indicator reported by the terminal device, the AI processing overhead and each processing model are introduced, which can reasonably measure the terminal device and effectively guarantee the efficient use of resources in the case that the resources for processing the units or capabilities corresponding to the second message of the terminal device are limited.

[0195] In summary, according to the technical scheme provided by the embodiments of the present disclosure, the terminal device sends the fourth message to the network device, and the network device can more accurately understand the processing capability of the terminal device, thereby making more reasonable scheduling and resource allocation decisions. This helps to reduce resource waste and improve the overall efficiency of the system. Further, since the fourth message can dynamically update the processing capability of the terminal device, it can more flexibly adapt to various communication environments and needs.

[0196] Further, for the CSI reporting scene of multiple streams, by configuring or reporting the load related information of different stream numbers occupied by the network device and the terminal device, the bits occupied by the PMI are adapted to the processing model implementation of the terminal device and the reported rank indicator RI, thereby improving the higher utilization rate of the bits in the AI-based CSI.
