技术领域technical field

本发明涉及通信技术领域，尤其涉及一种CSI反馈方法及装置、存储介质、终端、网络设备。The present invention relates to the field of communication technologies, and in particular, to a CSI feedback method and apparatus, a storage medium, a terminal, and a network device.

背景技术Background technique

无线信道条件是在不断变化的，假设在信道质量很好的情况下，若下行使用了正交相移键控(Quadrature Phase Shift Keying，QPSK)，而非更高阶的调制方式进行传输，则会降低对频谱的利用率，并造成吞吐量的下降。而假设在信道质量很差的情况下，若使用了高阶调制而非QPSK调制，则会造成过多的重传，也会使用过多的无线资源。无论是哪一种情况，都不能有效地利用无线资源。为了更好地适应无线信道的变化，用户设备(User Equipment，UE)可以通过信道状态信息(Channel State Information，CSI)将下行信道质量信息上报给基站(gNB)，以便gNB选择更好的调制与编码策略(Modulation and Coding Scheme，MCS)或者更合适的预编码矩阵(Precoder Matrix Indicator，PMI)等。The wireless channel conditions are constantly changing. Assuming that the channel quality is good, if the downlink uses Quadrature Phase Shift Keying (QPSK) instead of higher-order modulation for transmission, then It will reduce the utilization of the spectrum and cause a drop in throughput. Assuming that the channel quality is very poor, if high-order modulation is used instead of QPSK modulation, it will cause too many retransmissions and use too many wireless resources. In either case, radio resources cannot be effectively utilized. In order to better adapt to changes in wireless channels, user equipment (UE) can report downlink channel quality information to the base station (gNB) through channel state information (Channel State Information, CSI), so that the gNB can choose better modulation and A coding strategy (Modulation and Coding Scheme, MCS) or a more suitable precoding matrix (Precoder Matrix Indicator, PMI), etc.

具体地，UE通过测量接收到的信道状态信息参考信号(Channel State Information-Referance Signal，CSI-RS)来获取CSI，并上报给gNB的过程即为CSI反馈过程。CSI反馈过程包括上报秩指示(Rand Indicator，RI)、PMI和信道质量指示(Channel Quality Indicator，CQI)中的一个或者多个。其上报方式可以为周期、半持续和非周期等方式。如对于PMI的反馈的传统做法是：UE根据信道状态信息选择自己认为合适的PMI，然后上报给gNB，供其参考。但是这种方式的缺点是UE选择的PMI不一定合适，有可能造成UE间干扰。另外一种思路是：UE直接将信道信息反馈给gNB，gNB根据信道信息自己选择合适的PMI。然而，这种方式的缺点是信道信息的全反馈，开销太大，需要压缩后反馈。Specifically, the UE obtains CSI by measuring the received channel state information reference signal (Channel State Information-Reference Signal, CSI-RS), and the process of reporting it to the gNB is the CSI feedback process. The CSI feedback process includes reporting one or more of a rank indicator (Rand Indicator, RI), a PMI, and a channel quality indicator (Channel Quality Indicator, CQI). The reporting method can be periodic, semi-persistent and aperiodic. For example, the traditional method for PMI feedback is: the UE selects a PMI that it considers appropriate according to the channel state information, and then reports it to the gNB for its reference. However, the disadvantage of this method is that the PMI selected by the UE may not be suitable, which may cause interference between UEs. Another idea is that the UE directly feeds back the channel information to the gNB, and the gNB selects an appropriate PMI by itself according to the channel information. However, the disadvantage of this method is that the full feedback of the channel information is too expensive and needs to be fed back after compression.

由此，研究如何反馈CSI对于提升通信性能具有重要的实用价值，然而现有技术中的CSI反馈机制无法非常准确地上报信道信息。Therefore, studying how to feedback CSI has important practical value for improving communication performance, however, the CSI feedback mechanism in the prior art cannot report channel information very accurately.

具体实施方式Detailed ways

如背景技术所言，现有技术中的CSI反馈机制无法非常准确上报信道信息。As mentioned in the background art, the CSI feedback mechanism in the prior art cannot report channel information very accurately.

为解决上述问题，本发明实施例提供了一种CSI反馈方法，所述方法包括：根据CSI反馈信息的参数，生成CSI反馈信息；上报所述CSI反馈信息至网络设备。由此，UE能够自己选择生成CSI反馈信息使用的网络或者网络中间层，并据此上报CSI反馈信息。To solve the above problem, an embodiment of the present invention provides a CSI feedback method, the method includes: generating CSI feedback information according to parameters of the CSI feedback information; and reporting the CSI feedback information to a network device. In this way, the UE can select the network or the network middle layer used to generate the CSI feedback information, and report the CSI feedback information accordingly.

为使本发明的上述目的、特征和有益效果能够更为明显易懂，下面结合附图对本发明的具体实施例做详细的说明。In order to make the above objects, features and beneficial effects of the present invention more clearly understood, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

请参见图1，本发明实施例提供一种CSI反馈方法的流程示意图，该方法可由终端执行，所述终端可以为用户设备(User Equipment，简称UE)，以下以UE为例说明。在具体实施中，下述步骤S101～步骤S102所提供的CSI反馈方法可以由用户设备中的具有CSI反馈功能的芯片执行，也可以由用户设备中的基带芯片执行。Referring to FIG. 1 , an embodiment of the present invention provides a schematic flowchart of a CSI feedback method. The method may be executed by a terminal, and the terminal may be a user equipment (User Equipment, UE for short). The UE is used as an example for description below. In a specific implementation, the CSI feedback method provided by the following steps S101 to S102 may be executed by a chip with a CSI feedback function in the user equipment, or may be executed by a baseband chip in the user equipment.

AI(Artificial Intelligence,人工智能)在通信领域的应用越来越广泛，基于AI的CSI反馈机制也开始有较多研究。UE通过测量接收到的CSI-RS来获取CSI反馈信息，并上报给网络设备的过程称为 CSI反馈过程。其中，网络设备可以为接入点(Acess Point，简称AP)或者基站(如gNB、eNB等)。在UE侧和网络设备侧各自部署了一种或多种网络。AI (Artificial Intelligence, artificial intelligence) is more and more widely used in the field of communication, and there are also more researches on the CSI feedback mechanism based on AI. The process that the UE obtains the CSI feedback information by measuring the received CSI-RS and reports it to the network device is called the CSI feedback process. The network device may be an access point (Access Point, AP for short) or a base station (eg, gNB, eNB, etc.). One or more kinds of networks are respectively deployed on the UE side and the network device side.

可以把CSI反馈过程类比为压缩和恢复过程，UE侧利用深度学习网络(或称为神经网络，以下均统称为网络)对CSI-RS位置上的信道信息做压缩，生成CSI反馈信息，所述CSI反馈信息可以记作csi-codeword，并上报给网络设备。网络设备利用相对应的深度学习网络对所述CSI反馈信息做解压缩，恢复出CSI(CSI-RS位置上的信道信息)。但是深度学习算法应用到CSI反馈中会存在一些限制。为保证CSI反馈过程的准确性，UE侧需要能够确定对方能够使用正确的网络解码CSI反馈信息以恢复出信道信息。The CSI feedback process can be analogized to a compression and recovery process. The UE side uses a deep learning network (or a neural network, hereinafter collectively referred to as a network) to compress the channel information at the CSI-RS position to generate CSI feedback information. The CSI feedback information can be recorded as csi-codeword and reported to the network device. The network device decompresses the CSI feedback information by using the corresponding deep learning network, and recovers the CSI (channel information at the CSI-RS position). However, there are some limitations in the application of deep learning algorithms to CSI feedback. In order to ensure the accuracy of the CSI feedback process, the UE side needs to be able to determine that the other party can use the correct network to decode the CSI feedback information to recover the channel information.

所述CSI反馈方法包括：The CSI feedback method includes:

步骤S101，根据CSI反馈信息的参数，生成CSI反馈信息；Step S101, generating CSI feedback information according to parameters of the CSI feedback information;

步骤S102，上报所述CSI反馈信息至网络设备。Step S102, reporting the CSI feedback information to a network device.

所述CSI反馈信息的参数为与生成所述CSI反馈信息的网络或网络的中间层一一对应的参数。所述CSI反馈信息的参数可以包括上报至网络设备的CSI反馈信息的长度、属性等参数等。UE根据CSI反馈信息的参数确定网络以使用所述网络生成CSI反馈信息，并将CSI反馈信息上报给网络设备。The parameters of the CSI feedback information are parameters that correspond one-to-one with the network that generates the CSI feedback information or an intermediate layer of the network. The parameters of the CSI feedback information may include parameters such as the length and attributes of the CSI feedback information reported to the network device. The UE determines the network according to the parameters of the CSI feedback information to use the network to generate the CSI feedback information, and reports the CSI feedback information to the network device.

其中，每一网络可以确定一个或多个可用于生成CSI反馈信息的中间层，每一中间层生成的CSI反馈信息的参数(如CSI反馈信息的长度)不同。若CSI反馈信息的参数对应的网络仅包含一个可用于生成CSI反馈信息的中间层时，直接使用该中间层生成CSI反馈信息即可。Wherein, each network may determine one or more intermediate layers that can be used to generate CSI feedback information, and the parameters of the CSI feedback information generated by each intermediate layer (eg, the length of the CSI feedback information) are different. If the network corresponding to the parameter of the CSI feedback information includes only one intermediate layer that can be used to generate the CSI feedback information, the intermediate layer may be used directly to generate the CSI feedback information.

可选的，所述CSI反馈信息通过物理上行控制信道(Physical Uplink Control Channel，简称PUCCH)或者物理上行共享信道(Physical Uplink Shared Channel，简称PUSCH)上报至所述网络设备。Optionally, the CSI feedback information is reported to the network device through a Physical Uplink Control Channel (PUCCH for short) or a Physical Uplink Shared Channel (PUSCH for short).

本实施例中，UE自己更清楚信道状况和环境状况，可以灵活确定生成CSI反馈信息使用的网络或者网络中间层。例如，信道条件好，UE可上报长度较短的CSI反馈信息。由此，UE能够灵活选择生成CSI反馈信息使用的网络或者网络中间层，并据此上报CSI反馈信息。In this embodiment, the UE is more aware of the channel condition and the environment condition, and can flexibly determine the network or the network intermediate layer used to generate the CSI feedback information. For example, if the channel condition is good, the UE can report CSI feedback information with a shorter length. In this way, the UE can flexibly select the network or the network intermediate layer used to generate the CSI feedback information, and report the CSI feedback information accordingly.

在一个实施例中，所述方法还可以包括：在上报CSI反馈信息至所述网络设备的同时，将所述CSI反馈信息的长度上报至所述网络设备。In one embodiment, the method may further include: reporting the length of the CSI feedback information to the network device while reporting the CSI feedback information to the network device.

若UE自行选择了某一网络或某一网络的中间层生成CSI反馈信息，则UE在向网络设备上报CSI反馈信息时，将该CSI反馈信息的长度也一起上报给网络设备，以使得所述网络设备能够根据CSI反馈信息的长度确定对UE上报的CSI反馈信息进行解压缩的网络，并通过确定的网络对CSI反馈信息解压缩，恢复出UE的CSI。If the UE selects a certain network or an intermediate layer of a certain network to generate CSI feedback information, when the UE reports the CSI feedback information to the network equipment, the length of the CSI feedback information is also reported to the network equipment, so that the The network device can determine a network for decompressing the CSI feedback information reported by the UE according to the length of the CSI feedback information, and decompress the CSI feedback information through the determined network to recover the CSI of the UE.

在一个实施例中，所述CSI反馈信息的参数包括网络指示信息，图2示出图1中步骤S101的一个具体实施方式。具体的，步骤S101所述根据CSI反馈信息的参数生成CSI反馈信息，可以包括：In an embodiment, the parameters of the CSI feedback information include network indication information, and FIG. 2 shows a specific implementation of step S101 in FIG. 1 . Specifically, in step S101, generating the CSI feedback information according to the parameters of the CSI feedback information may include:

步骤S1011，确定所述网络指示信息；Step S1011, determining the network indication information;

步骤S1012，根据所述网络指示信息确定对应的网络或网络中间层，并根据确定的网络或网络中间层生成CSI反馈信息。Step S1012: Determine a corresponding network or network intermediate layer according to the network indication information, and generate CSI feedback information according to the determined network or network intermediate layer.

其中，网络指示信息为所述UE用于确定对应网络或网络中间层的信息。可选的，网络指示信息可以为网络的索引(index)或网络中间层的索引。可选的，可为UE侧和网络设备侧的每一网络设置索引，UE侧和网络设备侧对每一网络的索引的理解一致。可选的，各个网络的索引或网络中间层的索引可由网络设备通过***广播信息(如SIB等)或者RRC信令配置给UE。Wherein, the network indication information is information used by the UE to determine the corresponding network or the middle layer of the network. Optionally, the network indication information may be an index of the network or an index of a middle layer of the network. Optionally, an index may be set for each network on the UE side and the network device side, and the UE side and the network device side have the same understanding of the index of each network. Optionally, the index of each network or the index of the middle layer of the network can be configured to the UE by the network device through system broadcast information (such as SIB, etc.) or RRC signaling.

UE可根据网络设备配置的信息(如RRC信令或***广播消息等配置的信息)确定网络指示信息，也可以通过其他方式确定网络指示信息。需要说明的是，网络指示信息除了网络或网络中间层的索引，还可以为其他能够确定对应网络或网络中间层的信息，这里不再赘述。The UE may determine the network indication information according to the information configured by the network device (such as the information configured by the RRC signaling or the system broadcast message), and may also determine the network indication information in other ways. It should be noted that, in addition to the index of the network or the network intermediate layer, the network indication information may also be other information that can determine the corresponding network or the network intermediate layer, which will not be repeated here.

例如，网络的索引(index)与生成的CSI反馈信息长度之间的关系如表1所示。For example, the relationship between the index of the network and the length of the generated CSI feedback information is shown in Table 1.

表1Table 1

网络IndexNetwork Index	CSI反馈信息长度CSI feedback information length
11	5bits5bits
22	10bits10bits
33	20bits20bits
44	30bits30bits

或者，网络中间层的索引(index)与生成的CSI反馈信息长度之间的关系如表2所示。Alternatively, the relationship between the index (index) of the middle layer of the network and the length of the generated CSI feedback information is shown in Table 2.

表2Table 2

网络中间层IndexNetwork middle layer Index	CSI反馈信息长度CSI feedback information length
11	5bits5bits
22	10bits10bits
33	20bits20bits
44	30bits30bits

在一个实施例中，步骤S1011所述确定所述网络指示信息包括：接收配置信令，所述配置信令包括网络类型的指示信息；根据所述网络类型和CSI确定所述网络指示信息。In an embodiment, the determining of the network indication information in step S1011 includes: receiving configuration signaling, where the configuration signaling includes indication information of a network type; and determining the network indication information according to the network type and CSI.

其中，配置信令为网络设备发送至UE的信令，配置信令中包括网络类型的指示信息，该指示信息用于为UE指示生成CSI反馈信息的网络的网络类型。可选的，网络类型的指示信息可以为网络类型的索引(index)，可设置每一网络类型的索引，网络设备可在配置信令中携带某网络类型的索引以向UE指示对应的网络类型(如TypeNet)。可选的，配置信令为RRC信令等。The configuration signaling is signaling sent by the network device to the UE, and the configuration signaling includes indication information of the network type, where the indication information is used to indicate the network type of the network that generates the CSI feedback information for the UE. Optionally, the indication information of the network type can be an index of the network type, the index of each network type can be set, and the network device can carry the index of a certain network type in the configuration signaling to indicate the corresponding network type to the UE. (eg TypeNet). Optionally, the configuration signaling is RRC signaling or the like.

所述CSI为UE通过信道状态测量得到的信道状态信息(CSI)。UE可以根据配置信令指示的网络类型和UE测量得到的CSI确定所述网络指示信息。例如，若同一网络类型对应多个网络，UE可以根据CSI在该网络类型对应的多个网络中选择适合的网络，生成CSI反馈信息。The CSI is channel state information (CSI) obtained by the UE through channel state measurement. The UE may determine the network indication information according to the network type indicated by the configuration signaling and the CSI measured by the UE. For example, if the same network type corresponds to multiple networks, the UE may select a suitable network from the multiple networks corresponding to the network type according to the CSI, and generate CSI feedback information.

在一个具体实施例中，网络通过配置信令指示UE做CSI反馈信息上报，配置信令可以为RRC信令，该配置信令可以表示为AIcsi-feadback，其中包括网络类型的指示信息。具体地，UE和网络设备(如基站gNB)侧分别部署了若干类型网络，对应不同的CSI-RS配置，网络设备直接通过配置信令指示UE使用的网络类型。In a specific embodiment, the network instructs the UE to report CSI feedback information through configuration signaling. The configuration signaling may be RRC signaling, and the configuration signaling may be expressed as AIcsi-feadback, which includes network type indication information. Specifically, several types of networks are respectively deployed on the UE and network equipment (eg, base station gNB) side, corresponding to different CSI-RS configurations, and the network equipment directly indicates the network type used by the UE through configuration signaling.

在一个实施例中，步骤S1011所述确定所述网络指示信息包括：根据CSI-RS端口数确定网络类型的指示信息；根据所述网络类型的指示信息和CSI确定所述网络指示信息。In an embodiment, the determining of the network indication information in step S1011 includes: determining the indication information of the network type according to the number of CSI-RS ports; and determining the network indication information according to the indication information of the network type and CSI.

可选的，在现有协议中已经存在指示CSI-RS端口数(nrofPorts)的配置，UE根据配置的CSI-RS端口数确定网络类型的指示信息(如网络类型的索引)，从而确定网络类型。再根据确定的网络类型以及测量的CSI确定选择哪一网络或者网络中间层生成CSI反馈信息。此时，CSI-RS的端口数与所述网络类型的指示信息的参数之间存在第一对应关系，从而网络设备能够通过CSI-RS端口数隐式指示网络类型。Optionally, a configuration indicating the number of CSI-RS ports (nrofPorts) already exists in the existing protocol, and the UE determines the indication information of the network type (such as the index of the network type) according to the configured number of CSI-RS ports, thereby determining the network type. . Then, according to the determined network type and the measured CSI, it is determined which network or the middle layer of the network is selected to generate the CSI feedback information. At this time, there is a first correspondence between the number of CSI-RS ports and the parameters of the indication information of the network type, so that the network device can implicitly indicate the network type through the number of CSI-RS ports.

在一个具体实施例中，若网络配置的CSI-RS端口数的预设阈值以PortThreshold表示。当UE的CSI-RS端口数大于PortThreshold，UE根据CSI-RS端口数确定获取CSI反馈信息的网络类型，如TypeNet。每种网络类型包含若干网络，不同网络用于获取不同长度的CSI反馈信息(网络与CSI反馈信息的长度如表1)。进一步，当CSI-RS端口数小于等于PortThreshold时，AI算法可能没有增益，还是会用传统方式。In a specific embodiment, if the preset threshold of the number of CSI-RS ports configured by the network is represented by PortThreshold. When the number of CSI-RS ports of the UE is greater than PortThreshold, the UE determines the network type for acquiring the CSI feedback information, such as TypeNet, according to the number of CSI-RS ports. Each network type includes several networks, and different networks are used to obtain CSI feedback information of different lengths (the lengths of networks and CSI feedback information are shown in Table 1). Further, when the number of CSI-RS ports is less than or equal to PortThreshold, the AI algorithm may have no gain, and the traditional method will still be used.

在另一具体实施例中，若nrofPorts的取值{p1,p2,p4,p8,p12,p16, p24,p32}对应8种或几种网络类型的索引，如p1至p4对应网络类型的索引为1，p8值p16对应网络类型的索引为2，p24～p32对应网络类型的索引为3。In another specific embodiment, if the values of nrofPorts {p1, p2, p4, p8, p12, p16, p24, p32} correspond to the indexes of 8 or several network types, for example, p1 to p4 correspond to the indexes of the network types is 1, the p8 value p16 corresponds to the network type index of 2, and p24 to p32 corresponds to the network type index of 3.

在一个实施例中，步骤S1011所述确定所述网络指示信息包括：根据CSI-RS端口数和接收天线数确定网络类型的指示信息；根据所述网络类型的指示信息和CSI确定所述网络指示信息。In an embodiment, the determining of the network indication information in step S1011 includes: determining the indication information of the network type according to the number of CSI-RS ports and the number of receiving antennas; determining the network indication according to the indication information of the network type and CSI information.

可选的，在现有协议中已经存在指示接收天线数的配置，UE根据配置的CSI-RS端口数和接收天线数确定网络类型(TypeNet)的指示信息。UE根据网络配置的CSI-RS端口数和接收天线数确定网络类型的指示信息(如网络类型的索引)，从而确定网络类型。再根据确定的网络类型以及测量的CSI确定选择哪一网络或者网络中间层生成CSI反馈信息。Optionally, a configuration indicating the number of receiving antennas already exists in the existing protocol, and the UE determines the indication information of the network type (TypeNet) according to the configured number of CSI-RS ports and the number of receiving antennas. The UE determines the indication information of the network type (eg, the index of the network type) according to the number of CSI-RS ports and the number of receiving antennas configured by the network, so as to determine the network type. Then, according to the determined network type and the measured CSI, it is determined which network or the middle layer of the network is selected to generate the CSI feedback information.

进一步，所述CSI-RS的端口数和终端的接收天线数的组合与所述反馈信息的参数之间存在第二对应关系，所述第二对应关系被用于根据所述CSI-RS的端口数和所述终端的端口数确定网络类型的指示信息。Further, there is a second correspondence between the combination of the number of ports of the CSI-RS and the number of receiving antennas of the terminal and the parameter of the feedback information, and the second correspondence is used for the port according to the CSI-RS. The number and the port number of the terminal determine the indication information of the network type.

例如，可以按照接收天线数进行范围划分，得到n1至n2、n2至n3、n3至n4、≥n4等范围，nrofPorts的取值为{p1,p2,p4,p8,p12,p16,p24,p32}。则第二对应关系可以表示为：For example, the range can be divided according to the number of receiving antennas to obtain ranges such as n1 to n2, n2 to n3, n3 to n4, ≥n4, etc. The value of nrofPorts is {p1,p2,p4,p8,p12,p16,p24,p32 }. Then the second correspondence can be expressed as:

当nrofPorts为p1至p4时：接收天线数为n1至n2时，则对应的网络类型的索引为1；接收天线数为n2至n3时，对应的网络类型的索引为2；接收天线数为n3至n4时，对应的网络类型的索引为3；接收天线数为>＝n4时，对应的网络类型的索引为4；When nrofPorts is p1 to p4: when the number of receiving antennas is n1 to n2, the index of the corresponding network type is 1; when the number of receiving antennas is n2 to n3, the index of the corresponding network type is 2; the number of receiving antennas is n3 When reaching n4, the index of the corresponding network type is 3; when the number of receiving antennas is >=n4, the index of the corresponding network type is 4;

当nrofPorts为p8至p16时：接收天线数为n1至n2时，则对应的网络类型的索引为1；接收天线数为n2至n3时，对应的网络类型的索引为2；接收天线数为n3至n4时，对应的网络类型的索引为3；接收天线数为>＝n4时，对应的网络类型的索引为4；When nrofPorts is from p8 to p16: when the number of receiving antennas is from n1 to n2, the index of the corresponding network type is 1; when the number of receiving antennas is from n2 to n3, the index of the corresponding network type is 2; the number of receiving antennas is n3 When reaching n4, the index of the corresponding network type is 3; when the number of receiving antennas is >=n4, the index of the corresponding network type is 4;

当nrofPorts为p24至p32时：接收天线数为n1至n2时，则对应的网络类型的索引为1；接收天线数为n2至n3时，对应的网络类型的索引为2；接收天线数为n3至n4时，对应的网络类型的索引为3；接收天线数为>＝n4时，对应的网络类型的索引为4；When nrofPorts is from p24 to p32: when the number of receiving antennas is from n1 to n2, the index of the corresponding network type is 1; when the number of receiving antennas is from n2 to n3, the index of the corresponding network type is 2; the number of receiving antennas is n3 When reaching n4, the index of the corresponding network type is 3; when the number of receiving antennas is >=n4, the index of the corresponding network type is 4;

需要说明的是，网络类型的指示信息和nrofPorts以及接收天线数之间的第二对应关系可根据需要设定，包括但不限于上述关系。It should be noted that the second correspondence between the indication information of the network type and the nrofPorts and the number of receiving antennas may be set as required, including but not limited to the above-mentioned relationship.

本实施例中，网络设备通过CSI-RS端口数或接收天线数隐式指示网络类型的指示信息，节约指示资源。In this embodiment, the network device implicitly indicates the indication information of the network type through the number of CSI-RS ports or the number of receiving antennas, thereby saving indication resources.

在一个实施例中，所述网络指示信息可以由网络设备指示，相应的，图2中步骤S1012所述根据所述网络指示信息确定对应的网络之后，本实施方案还可以包括：根据CSI从确定的网络中选择中间层。进一步，步骤S1012所述根据确定的网络生成CSI反馈信息可以包括：根据选择的中间层生成CSI反馈信息。In one embodiment, the network indication information may be indicated by a network device. Correspondingly, after the corresponding network is determined according to the network indication information in step S1012 in FIG. 2 , this embodiment may further include: determining the corresponding network according to the CSI Select the middle layer in the network. Further, the generating of the CSI feedback information according to the determined network in step S1012 may include: generating the CSI feedback information according to the selected intermediate layer.

此时，所述网络指示信息由网络设备直接指示给UE，UE确定对应的网络之后，若该网络存在多个可用于生成CSI反馈信息的中间层，则UE根据测量得到的CSI自己选择中间层，以生成CSI反馈信息。At this time, the network indication information is directly indicated to the UE by the network device. After the UE determines the corresponding network, if the network has multiple intermediate layers that can be used to generate CSI feedback information, the UE selects the intermediate layer according to the measured CSI. , to generate CSI feedback information.

本实施例中，网络设备指示确定的网络，UE根据CSI在该确定的网络中选择生成CSI反馈信息的中间层。In this embodiment, the network device indicates a determined network, and the UE selects an intermediate layer that generates CSI feedback information in the determined network according to the CSI.

在一个具体应用中，CSI反馈基于AI实现，以CSI反馈信息的长度为例说明本发明实施例的应用场景。把CSI反馈过程类比为压缩和恢复过程，UE侧利用网络对CSI-RS位置上的信道信息做压缩以生成CSI反馈信息，并反馈给gNB。gNB利用相对应的网络对CSI反馈信息做解压缩，恢复出CSI-RS位置上的信道信息。如图3和图4所示，图3为本发明实施例中一种UE侧的CSI反馈方法的示意图，图4为一种gNB侧的CSI反馈方法的示意图。In a specific application, the CSI feedback is implemented based on AI, and the length of the CSI feedback information is used as an example to illustrate the application scenario of the embodiment of the present invention. The CSI feedback process is analogous to the compression and recovery process. The UE side uses the network to compress the channel information on the CSI-RS position to generate CSI feedback information and feed it back to the gNB. The gNB uses the corresponding network to decompress the CSI feedback information to recover the channel information at the CSI-RS position. As shown in FIG. 3 and FIG. 4 , FIG. 3 is a schematic diagram of a UE-side CSI feedback method according to an embodiment of the present invention, and FIG. 4 is a schematic diagram of a gNB-side CSI feedback method.

针对图3中的UE侧网络，输入(Input)为CSI-RS的信道矩阵 (记作H)，H经过S301压缩和S303量化两个步骤得到的CSI反馈信息(csi-Codeword)。其中，步骤S301压缩包括：将H经过神经网络(Conv2D)(即本文中指的网络)进行卷积计算，并经过全连接层(Dense)处理得到压缩结果。步骤S303可通过量化器(Quantizer)实现。For the UE side network in Fig. 3, the input (Input) is the channel matrix of the CSI-RS (denoted as H), and H is the CSI feedback information (csi-Codeword) obtained through the two steps of S301 compression and S303 quantization. The compression in step S301 includes: performing convolution calculation on H through a neural network (Conv2D) (that is, the network referred to in this document), and obtaining a compression result through a fully connected layer (Dense) process. Step S303 may be implemented by a quantizer (Quantizer).

UE侧在执行步骤S301之后，还执行步骤S302解压缩，以得到恢复出的CSI-RS的信道矩阵H，也即输出(Output)。其中，步骤S302解压缩的操作与步骤S301的压缩操作相反，即压缩结果经全连接层(Dense)逆处理后再经神经网络(Conv2D)进行逆卷积计算，将压缩结果恢复到信道矩阵H。其中，量化可以为均匀量化也可以为非均匀量化。After performing step S301, the UE side also performs step S302 for decompression, so as to obtain the recovered channel matrix H of the CSI-RS, that is, the output (Output). Wherein, the decompression operation in step S302 is opposite to the compression operation in step S301, that is, the compression result is inversely processed by the fully connected layer (Dense), and then deconvolution calculation is performed by the neural network (Conv2D), and the compression result is restored to the channel matrix H. . The quantization may be uniform quantization or non-uniform quantization.

针对图4中的gNB侧网络，输入(Input)为基站gNB接收到的并消除量化误差(Dequantizer)的CSI反馈信息(csi-Codeword)，输出(Output)为恢复出的CSI-RS的信道矩阵H，其中，恢复的操作主要指的是对CSI反馈信息进行解压缩，也即将消除量化误差的CSI反馈信息经全连接层(Dense)逆处理后再经网络(Conv2D)进行逆卷积计算。由此可以看出，本示例中UE获取CSI反馈信息的网络或网络中间层和gNB恢复信道信息的网络或网络中间层是一一对应的。For the gNB side network in Figure 4, the input (Input) is the CSI feedback information (csi-Codeword) received by the base station gNB and dequantizer (Dequantizer), and the output (Output) is the recovered CSI-RS channel matrix H, where the recovery operation mainly refers to decompressing the CSI feedback information, that is, the CSI feedback information that eliminates the quantization error is inversely processed by the fully connected layer (Dense) and then deconvolution calculated by the network (Conv2D). It can be seen from this that in this example, the network or network middle layer where the UE obtains the CSI feedback information and the network or network middle layer where the gNB restores the channel information are in a one-to-one correspondence.
