为了能够更加详尽地了解本申请实施例的特点和技术内容,下面结合附图对本申请实施例的实现进行详细阐述,所附附图仅供参考说明之用,并非用来限定本申请实施例。
在对本申请实施例提供的信道状态信息处理方法进行详细说明之前,先对CSI进行简要说明。
终端设备向网络设备反馈CSI在LTE系统及NR系统中具有至关重要的作用,CSI决定了多输入多输出(Multiple-Input Multiple-Output MIMO)传输的性能。通常,终端设备通过向网络设备发送CSI指示信息来反馈CSI;所述CSI指示可以包括信道质量指示(Channel Quality Indication,CQI)、预编码矩阵指示(Precoding Matrix Indication,PMI)和秩指示(Rank Indication,RI)中的任意一种或多种。终端设备反馈CSI指示信息的流程,如图1所示,网络设备为终端设备配置CSI参考信号及待反馈参数,其中,所述CSI参考信号用于CSI测量,所述CSI参考信号可以包括同步信号块(Synchronization Signal,SSB)和/或信道状态信息参考信号(Channel-State Information Reference Signal,CSR-RS),待反馈参数为网络设备需要终端设备反馈CQI、PMI和RI中的哪一个或哪几个。终端设备通过对CSI参考信号的测量,能够确定CSI;终端设备向网络设备反馈表征CSI的CSI指示信息。网络设备根据CSI指示信息,能够获取相应的CSI,并根据获取的CSI为终端设备配置数据传输方式。
下面再对神经网络模型进行简要说明。简单神经网络模型的结构,如图2所示,包括:输入层、隐藏层和输出层。其中,输入层负责接收数据,隐藏层对输入层接收的数 据进行处理,输出层用于输出数据处理的结果。神经网络模型中的每个节点代表一个处理单元,每个节点可以认为是模拟了一个神经元,多个神经元组成一层神经网络;通过多层的信息传输与处理构造出一个整体的神经网络模型。
随着对神经网络模型的不断深入研究,提出了深度神经网络模型,深度神经网络模型的结构如图3所示,相比较基础神经网络模型,深度神经网络模型具有较多的隐藏层,通过对多隐藏层的神经网络模型逐层训练进行特征学习,极大地提升了神经网络模型的学习和处理能力。深度神经网络模型在模式识别、信号处理、优化组合以及异常探测等方便具有广泛的应用。
通常,终端设备获取CSI以及终端设备向网络设备反馈CSI均是根据传统的基本通信模型以及预配置的反馈参数集合、基于量化和码本的方式实现的。但是,基于量化和码本进行信道状态信息反馈的方法通常不能精确地反映当前信道的实际信道状态信息。尤其是在大规模的MIMO引入的情况下,将导致系统吞吐量上限的受限。
基于上述问题,本申请提供一种信道状态信息处理方法,本申请实施例的信道状态信息处理方法可以应用于各种通信系统,例如:全球移动通讯(global system of mobile communication,GSM)系统、码分多址(code division multiple access,CDMA)系统、宽带码分多址(wideband code division multiple access,WCDMA)系统、通用分组无线业务(general packet radio service,GPRS)、长期演进(long term evolution,LTE)系统、LTE频分双工(frequency division duplex,FDD)系统、LTE时分双工(time division duplex,TDD)系统、先进的长期演进(advanced long term evolution,LTE-A)系统、新无线(new radio,NR)系统、NR系统的演进系统、非授权频段上的LTE(LTE-based access to unlicensed spectrum,LTE-U)系统、非授权频段上的NR(NR-based access to unlicensed spectrum,NR-U)系统、通用移动通信系统(universal mobile telecommunication system,UMTS)、全球互联微波接入(worldwide interoperability for microwave access,WiMAX)通信系统、无线局域网(wireless local area networks,WLAN)、无线保真(wireless fidelity,WiFi)、下一代通信系统或其他通信系统等。
通常来说,传统的通信系统支持的连接数有限,也易于实现,然而,随着通信技术的发展,移动通信系统将不仅支持传统的通信,还将支持例如,设备到设备(device to device,D2D)通信,机器到机器(machine to machine,M2M)通信,机器类型通信(machine type communication,MTC),以及车辆间(vehicle to vehicle,V2V)通信等,本申请实施例也可以应用于这些通信系统。
