- the transmitter can optimize the signal transmission based on CSI to make it more compatible with the channel state.
- the channel quality indicator CQI
- MCS modulation and coding scheme
- PMI precoding matrix indicator
- MIMO multi-input multi-output
- the base station sends a Channel State Information Reference Signal (CSI-RS) on certain time-frequency resources in a certain time slot.
- CSI-RS Channel State Information Reference Signal
- the terminal performs channel estimation based on the CSI-RS, calculates the channel information on this time slot, and feeds back the PMI to the base station through the codebook.
- the base station combines the channel information based on the codebook information fed back by the terminal, and uses this to perform data precoding and multi-user scheduling before the next CSI report.
- the terminal can change the PMI reported for each subband to reporting the PMI according to the delay. Since the channels in the delay domain are more concentrated, the PMI of all subbands can be approximately represented by PMIs with fewer delays, that is, the delay domain information is compressed before reporting.
- the base station can pre-code the CSI-RS in advance and send the encoded CSI-RS to the terminal.
- the terminal sees the channel corresponding to the encoded CSI-RS.
- the terminal only needs to select several ports with higher strength from the ports indicated by the network side and report the coefficients corresponding to these ports.
- the terminal and the network side device may use a neural network or machine learning method to transmit the channel information.
- the terminal compresses and encodes the channel information through the AI model, and the base station decodes the compressed content through the corresponding AI model to restore the channel information.
- the AI model for decoding on the base station side and the AI model for encoding on the terminal side need to be jointly trained to achieve a reasonable match.
- the input of the encoding AI model is channel information
- the output is the encoding information, that is, the channel feature information.
- the input of the decoding AI model is the encoding information, and the output is the restored channel information.
- the main evaluation indicator of the AI model is the correlation between the input channel information and the recovered channel information. If the two are exactly the same, it means that the AI model has achieved perfect compression. Usually, the AI model can be considered effective if the correlation loss is within a certain degree. If the correlation loss exceeds the traditional non-AI method, such as the Type II codebook, the AI model can be replaced by the traditional codebook.
- CSI compression based on AI models is divided into encoding AI models and decoding AI models.
- the encoding AI model is on the terminal side
- the decoding AI model is on the network side device. If the terminal does not have a decoding AI model, it cannot obtain the channel information recovered by the network side device, and it cannot compare the original channel information with the recovered channel information. Therefore, the detection of the AI model needs to be performed on the network side device. Although the network side device has the recovered channel information, it does not have the original channel information, so it cannot be compared. Therefore, in order to be able to recover the results of the AI model on the network side device To monitor, the terminal needs to provide the original channel information. However, reporting the original channel information requires a lot of overhead, which will also lead to an increase in the transmission overhead between the terminal and the network side device. In view of these situations, the embodiment of the present application proposes a CSI transmission method.

- the terminal reports a first CSI for monitoring the performance of the AI unit, or reports the first CSI and a second CSI obtained based on the AI unit, wherein the first CSI is a CSI obtained based on a non-AI method, and then
- the network side device can compare the first CSI with the channel information recovered based on the AI unit to determine the degree of recovery of the channel information by the AI unit, and thus can know the performance of the AI unit, which helps the network side device to switch failed or low-performance AI units in time based on the performance of the AI unit, or change the transmission method of CSI, and more effectively ensure the transmission of CSI between the terminal and the network side device.
- the network side device can finally determine the performance of the AI unit based on the first CSI, so that there is no need to determine the performance of the AI unit by transmitting the AI unit between the terminal and the network side device, which effectively saves the transmission overhead between the terminal and the network side device.

为更好地理解本申请实施例提供的技术方案,以下对本申请实施例中可能涉及的相关
概念及原理进行解释说明。
由信息论可知,准确的信道状态信息(Channel State Information,CSI)对信道容量的至关重要。尤其是对于多天线系统来讲,发送端可以根据CSI优化信号的发送,使其更加匹配信道的状态。例如:信道质量指示(Channel Quality Indicator,CQI)可以用来选择合适的调制编码方案(Modulation and Coding Scheme,MCS)实现链路自适应;预编码矩阵指示(Precoding Matrix Indicator,PMI)可以用来实现特征波束成形(eigen beamforming)从而最大化接收信号的强度,或者用来抑制干扰(如小区间干扰、多用户之间干扰等)。因此,自从多天线技术(multi-input multi-output,MIMO)被提出以来,CSI获取一直都是研究热点。
通常,基站在在某个时隙(slot)的某些时频资源上发送信道状态信息参考信号(Channel State Information Reference Signal,CSI-RS),终端根据CSI-RS进行信道估计,计算这个时隙上的信道信息,通过码本将PMI反馈给基站,基站根据终端反馈的码本信息组合出信道信息,在下一次CSI上报之前,基站以此进行数据预编码及多用户调度。
为了进一步减少CSI反馈开销,终端可以将每个子带上报PMI改成按照延迟(delay)上报PMI,由于delay域的信道更集中,用更少的delay的PMI就可以近似表示全部子带的PMI,即将delay域信息压缩之后再上报。
同样,为了减少开销,基站可以事先对CSI-RS进行预编码,将编码后的CSI-RS发送给终端,终端看到的是经过编码之后的CSI-RS对应的信道,终端只需要在网络侧指示的端口中选择若干个强度较大的端口,并上报这些端口对应的系数即可。
进一步地,为了更好地压缩信道信息,终端和网络侧设备可以使用神经网络或机器学习的方法进行信道信息的传递。
具体地,在终端对通过AI模型对信道信息进行压缩编码,在基站通过对应的AI模型对压缩后的内容进行解码,从而恢复信道信息。此时基站侧进行解码的AI模型和终端侧进行编码的AI模型需要联合训练,达到合理的匹配度。编码AI模型的输入是信道信息,输出是编码信息,即信道特征信息,解码AI模型的输入是编码信息,输出是恢复的信道信息。
AI模型的主要评价指标是输入的信道信息和恢复的信道信息的相关性,如果二者完全相同说明AI模型实现了完美压缩,通常相关性损失在一定程度内可以认为AI模型是有效的,如果相关性损失超过传统的非AI方法,例如类型2(TypeII)码本,则AI模型可以替换为传统的码本。
如前所述,基于AI模型的CSI压缩分为编码AI模型和解码AI模型,通常编码AI模型在终端侧,解码AI模型在网络侧设备,终端如果没有解码AI模型也就无法获得网络侧设备恢复的信道信息,也就无法对原始的信道信息和恢复的信道信息进行比较,所以对AI模型的检测需要在网络侧设备进行,而网络侧设备虽然有恢复的信道信息但是没有原始的信道信息,也就无法进行比较。因此,为了能够在网络侧设备对AI模型的恢复结果
进行监控,需要终端提供原始的信道信息。但是,原始的信道信息上报需要很大的开销,这也就会导致终端和网络侧设备间传输开销的增大。针对这些情况,本申请实施例提出了一种CSI传输方法。
下面结合附图,通过一些实施例及其应用场景对本申请实施例提供的CSI传输方法进行详细地说明。
请参照图2,图2是本申请实施例提供的一种CSI传输方法的流程图,所述方法应用于终端。如图2所示,所述方法包括以下步骤:
步骤201、终端获取第一信息,所述第一信息用于指示第一CSI的上报位置,所述第一CSI为用于检测AI单元性能的CSI。
可选地,所述第一信息可以是网络侧设备发送的,网络侧设备通过第一信息指示第一CSI的上报位置,终端基于所述第一信息也就能够确定第一CSI的上报位置,进而终端也就能够在该上报位置上报第一CSI。
其中,所述第一CSI为用于检测AI单元性能的CSI,例如,所述第一CSI可以是基于非AI方式得到的CSI,如基于码本计算得到的CSI。需要说明地,所述AI单元也可称为AI模型、AI结构等,或者所述AI单元也可以是指能够实现与AI相关的特定的算法、公式、处理流程等的处理单元,本申请实施例对此不做具体限定。所述AI单元性能可以是指所述AI单元的模型精度、模型损失、对信道信息的恢复程度等。
步骤202、所述终端基于所述第一信息上报所述第一CSI,或者上报所述第一CSI和第二CSI,所述第二CSI为基于所述AI单元得到的CSI。
可以理解地,所述第一信息用于指示第一CSI的上报位置,则终端可以是基于所述第一信息上报所述第一CSI,也即上报用于监测AI单元的CSI,网络侧设备在接收到所述第一CSI后,可以是与自身通过AI单元恢复的信道信息进行比对,进而以获取AI单元的性能。
需要说明地,所述终端侧包括第一AI单元,所述第一AI单元用于对原始信道信息进行编码处理后输出信道特征信息,终端上报所述信道特征信息,也即将所述信道特征信息发送给网络侧设备;网络侧设备包括第二AI单元,网络侧设备将所述信道特征信息作为第二AI单元的输入,第二AI单元对所信道特征信息进行解码处理后输出恢复的信道信息。这样,终端和网络侧设备也就能够基于第一AI单元和第二AI单元实现对信道信息的传输。
本申请实施例中,所述第二CSI可以是基于所述第一AI单元得到的CSI,终端也可以是上报所述第一CSI和所述第二CSI,网络侧设备可以是将所述第二CSI作为第二AI单元的输入,并获取第二AI单元输出的信道信息,进一步地,网络侧设备可以是通过所述第一CSI恢复信道信息,将恢复的信道信息和第二AI单元输出的信道信息进行比对,进而以确定第二AI单元的性能,例如可以确定出第二AI单元对于信道信息的恢复程度。
本申请实施例中,终端通过上报用于监测AI单元性能的第一CSI,或者上报所述第一CSI和基于AI单元得到的第二CSI,所述第一CSI为基于非AI方式得到的CSI,进而
网络侧设备能够基于所述第一CSI和基于AI单元恢复的信道信息进行比对,从而以确定AI单元对于信道信息的恢复程度,也就能够获知AI单元的性能,有助于网络侧设备能够基于所述AI单元的性能来及时切换失效或性能较低的AI单元,或者是更换CSI的传输方式,更有效地保障了终端和网络侧设备之间CSI的传输。另外,终端通过上报通过非AI方式获得的第一CSI,网络侧设备也即能够基于所述第一CSI来最终确定AI单元的性能,从而终端和网络侧设备之间无需通过传输AI单元来确定AI单元的性能,有效节省了终端和网络侧设备之间的传输开销。
可选地,所述第一信息还用于指示所述第二CSI的上报位置。例如,网络侧设备发送的所述第一信息还用于指示第二CSI的上报位置,进而终端也就能够基于所述第一信息在相应的位置上报所述第二CSI。这样,也就通过第一信息来明确基于AI得到的第二CSI和基于非AI得到的第一CSI的上报位置,有效规范了第一CSI和第二CSI的上报。
本申请实施例中,所述终端获取第一信息,包括如下任意一项:
所述终端获取网络侧设备配置的第一CSI报告配置,所述第一CSI报告配置用于指示所述第一CSI的上报位置和第二CSI的上报位置;

可选地,在一种实施方式中,网络侧设备配置一个CSI报告位置(也即所述第一CSI报告配置),通过该第一CSI报告配置(report config)来同时指示第一CSI的上报位置和第二上报位置。
或者,在另一种实施方式中,网络侧设备分别配置两个CSI报告配置(也即所述第二CSI报告配置和第三CSI报告配置),通过这两个CSI报告配置分别来指示第二CSI的上报位置和第一CSI的上报位置。这样,也就分别通过不同的CSI报告配置来指示基于AI得到的CSI的上报位置和基于非AI方式得到的CSI的上报位置,从而以更规范CSI的上报方式。需要说明的是,网络侧设备也可以是只配置第二CSI报告配置或第三CSI报告配置,例如网络侧设备可以是只配置第三CSI报告配置,以指示用于监测AI单元性能的所述第一CSI的上报位置,终端对于基于AI单元得到的所述第二CSI可以是仍然按照正常
的上报方式进行上报。
又或者,在另一种实施方式中,网络侧设备还可以是通过第一指示信息直接指示一个CSI报告配置标识(Identity,ID),或者指示CSI-RS资源,或者直接指示第一CSI上报的时频位置和/或第二CSI上报的时频位置,终端根据所述网络侧设备的第一指示信息找到对应的时频位置进行信道检测,或者使用之前在对应位置缓存的信道信息计算基于非AI方式的CSI信息并上报。
又或者,如果终端上报的CSI(第一CSI,或者第一CSI和第二CSI)通过基于码本的信道信息上报,网络侧设备发送的第一指示信息还可以用于指示码本的配置信息,进而网络侧设备通过指示所述码本的配置信息,也就明确了终端通过基于码本的信道信息上报的CSI的形式。

需要说明地,网络侧设备在配置一个CSI报告配置(也即所述第一CSI报告配置)的情况下,所述第一CSI报告配置ID还用于指示所述第二CSI的上报位置。可以理解地,所述第一CSI报告配置ID可以是与第二CSI的上报位置对应,也即不同的ID对应不同的上报位置,进而通过第一CSI报告配置ID也即能够指示第二CSI的上报位置,从而无需再额外指示第二CSI的上报位置,能够有效节省传输开销。

也就是说,所述第三CSI报告配置中可以携带一个CSI report config ID,终端可以是使用这个ID对应的CSI report config中的CSI-RS资源进行信道估计。
需要说明地,所述第二CSI报告配置和所述第三CSI报告配置可以是由网络侧设备在CSI检测之前配置给所述终端。
或者,所述第三CSI报告配置也可以是后配置,这种情况下,网络侧设备需要通知终端进行对AI单元性能的监控,终端开始缓存信道测量结果,后续网络侧设备配置所述第三CSI报告配置,携带一个历史的CSI report config ID,终端使用缓存的信道矩阵计算对应的基于码本的CSI信息并上报。

例如,终端在基于AI的周期性地上报第二CSI的状态下,网络侧设备可以通知终端进行非AI方式的CSI(如PMI)的上报,终端在下一次或下几次进行CSI上报的时候,使用码本的方式上报CSI(也即所述第一CSI),然后再自动切换回基于AI的CSI(也即所述第二CSI)的上报。网络侧设备在接收到第一CSI之后,恢复基于码本的预编码矩阵,并与上一次或上几次接收到的第二CSI恢复的预编码矩阵进行比较,进而以确定AI单元的性能。这样,终端也就无需每次都上报第一CSI和第二CSI,有效节省了传输开销。
可选地,所述第一信息还包括上报的所述第一CSI的次数以及周期,进而也就使得所述网络侧设备能够获知终端上报用于监测的所述第一CSI的次数和周期,更有助于保障网络侧设备对于第一CSI的准确接收。

可选地,所述方法还包括:
