为使本申请的目的、技术方案和优点更加清楚,下面将结合附图对本申请实施方式作进一步地详细描述。
首先,对本申请实施例中涉及的名词进行简单介绍:
信道状态信息(Channel State Information,CSI):
CSI是用于描述通信链路的信道属性的信息。CSI的指示在通信系统中非常重要,其决定了多入多出(Multiple-Input Multiple-Output,MIMO)传输的性能。一般来说,通信系统中的CSI指示可以包括对信道质量指示(Channel Quality Indicator,CQI)、预编码矩阵指示(Precoding Matrix Indicator,PMI)、秩指示(Rank indicator,RI)等信息的指示。
结合参考图1,对CSI的生成与指示方式进行示例性的说明。如图1所示,网络设备可以为终端设备配置用于CSI指示的指示参数信息,例如:终端设备需要指示CQI、PMI、RI等信息中的哪些信息;同时,网络设备可以为终端设备配置一些供CSI测量用的参考信号,例如:同步信号块(Synchronization Signal Block,SSB)和/或信道状态信息参考信号(Channel State Information-Reference Signal,CSI-RS)。终端设备通过对上述参考信号的测量,确定当前信道状态信息情况,并根据网络设备配置的指示参数信息向网络设备指示当前的CSI反馈信息,从而供网络设备基于当前信道情况配置出合理高效的数据传输方式。
人工智能(Artificial Intelligence,AI):
近年来,以神经网络为代表的人工智能研究在很多领域都取得了非常大的成果,其也将在未来很长的一段时间内,对人们的生产生活起到重要的影响。
请参考图2,其示出了本申请一个实施例提供的神经网络的示意图。如图2所示,一个简单的神经网络的基本结构包括:输入层、隐藏层和输出层。其中,输入层负责接收数据,隐藏层负责处理数据,而最后的结果在输出层产生。如图3所示,各个节点代表一个处理单元,也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,多层的信息传递与处理构造出了一个整体的神经网络。
随着神经网络研究的不断发展,近年来,神经网络深度学习算法被提出,较多的隐藏层被引入,通过多隐藏层的神经网络逐层训练进行特征学习,极大地提升了神经网络的学习和处理能力,并在模式识别、信号处理、优化组合、异常探测等方面被广泛应用。
同时,随着深度学习的发展,卷积神经网络也被进一步地研究。请参考图3,其示出了本申请一个实施例提供的卷积神经网络的示意图。如图3所示,在一个卷积神经网络中,其基本结构包括:输入层、多个卷积层、多个池化层、全连接层及输出层。卷积层和池化层的引入,有效地控制了网络参数的剧增,限制了参数的个数并挖掘了局部结构的特点,提高了算法的鲁棒性。
信道状态信息指示与人工智能的结合
相关技术中,无线通信系统的基础原理大多还是基于对实际通信环境的理论建模与参数选取来完成的。随着对无线通信系统灵活性、适应性、速率以及容量等要求的进一步增强,传统的基于经典模型理论的无线通信系统工作方式所能带来的增益正在逐渐弱化。目前,已有一些新的研究针对上述问题逐步开展,利用人工智能的方式做CSI的获取与指示就是其中之一。
请参考图4,其示出了本申请一个实施例提供的利用神经网络模型做信道状态信息指示的网络架构的示意图。如图4所示,编码端先调用编码端神经网络对待反馈信道信息进行编码,以生成第一信道信息,第一信道信息也即CSI反馈信息;解码端在接收到第一信道信息之后,调用解码端神经网络对第一信道信息进行解码,得到反馈信道信息。
在上述基于人工智能的CSI反馈方式中,所反馈的第一信道信息的大小与反馈性能有直接的关联关系,反馈的第一信道信息的信息量越多,编码端对应的反馈信道信息对解码端对应的待反馈信道信息的恢复程度也就越高。在这种情况下,第一信道信息的反馈开销与待反馈信道信息的恢复增益之间是存在矛盾的。一方面,从通信系统的开销角度来看,传输第一信道信息所需的反馈开销需要越小越好,另一方面,从通信系统的传输性能增益来看,待反馈信道信息在解码端的恢复程度越高,对通信系统的性能增益越有利。
综上,有必要在基于人工智能的CSI反馈研究中,设计一种CSI反馈信息的量化方案,保证传输性能增益的条件下,尽可能地降低反馈开销。
相关技术中,针对CSI反馈信息的量化方案是采用统一量化方案,比如均匀量化,μ率量化等,上述量化方式对于CSI反馈信息没有明确规律时是有效的。
但是,通过实验分析可以发现,对于特定的信道特征来说,CSI反馈信息中的有些数据明显偏小,有些数据又明显偏大,且差距较大,这时候如果用统一的均匀量化或者其他统一量化作为量化策略的话是有缺陷的。例如:如果用统一的均匀量化,在同样比特数下,为了保证较大数据能够反馈而采用相对较大的量化粒度,而相对较大的量化粒度会导致较小数据的反馈误差增大。例如:为了保证较小数据的反馈精度而采用相对较小的量化粒度,则会导致反馈较大数据时需要相对更多的比特数。
针对上述问题,本申请实施例提出一种信息量化方法,主要用于基于人工智能的CSI反馈过程当中,以在保证量化精度的情况下,最大程度地降低反馈开销。下面,结合如下实施例对本申请的技术方案进行介绍说明。

终端设备14可以包括各种具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其他处理设备,以及各种形式的用户设备,移动台(Mobile Station,MS),终端(terminal device)等等。为方便描述,上面提到的设备统称为终端。网络设备120与终端设备14之间通过某种空口技术互相通信,例如Uu接口。

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),车辆间(Vehicle to Vehicle,V2V)通信以及车联网(Vehicle to Everything,V2X)系统等。本申请实施例也可以应用于这些通信系统。
图6示出了本申请一个示例性实施例提供的信息量化方法的流程图。该方法可以应用于如图5示出的通信系统中,该方法包括:
步骤610,终端设备与网络设备之间进行交互以确定目标分组量化方案。
终端设备与网络设备之间进行交互,以使得终端设备和网络设备确定目标分组量化方案。
由于终端设备与网络设备两侧需要统一量化方案,使得终端设备在对CSI反馈信息使用量化方案进行量化后,网络设备能够基于相同的量化方案获取正确的CSI反馈信息。所以,在步骤610中,终端设备与网络设备两侧确定相同的目标分组量化方案。可选的,终端设备与网络设备之间通过执行至少一次交互,以使得终端设备与网络设备确定目标分组量化方案。
步骤620,终端设备基于目标分组量化方案对CSI反馈信息进行分组,按照分组对应的量化方式对分组中的CSI反馈信息进行量化。
在本申请实施例中,目标分组量化方案是采用分组的形式对CSI反馈信息进行量化的一种量化方案。其中,存在至少两个分组对应于不同的量化方式。
也即,在目标分组量化方案中,支持将CSI反馈信息划分为n个分组进行反馈,n为不小于2的正整数,n个分组分别一一对应n种量化方式。可选的,n种量化方式互不相同。可选的,n种量化方式存在至少两种量化方式不相同。
示例性的,目标分组量化方案中包括3个分组:第一分组、第二分组以及第三分组,第一分组对应于第一量化方式,第二分组对应于第二量化方式,第三分组对应于第三量化方式。第一量化方式至第三量化方式互不相同。
终端设备在确定好目标分组量化方案后,根据目标分组量化方案的指示,对CSI反馈信息进行分组,再将每一分组的CSI反馈信息按照该分组对应的量化方式进行量化。上述分组量化也可以理解为是一种分类量化,通过对不同分布特征的CSI反馈信息加以分类从而进入不同的分组,再根据目标分组量化方案进行不同量化方式下的量化。
示例性的,目标分组量化方案中包括3个分组:第一分组、第二分组以及第三分组,第一分组对应于第一量化方式,第二分组对应于第二量化方式,第三分组对应于第三量化方式。终端设备将一部分CSI反馈信息分类至第一分组,采用第一量化方式进行量化,将另一部分CSI反馈信息分类至第二分组,采用第二量化方式进行量化,将另一部分CSI反馈信息分类至第三分组,采用第三量化方式进行量化。
可以理解的是,不同分组所对应的CSI反馈信息具有各自的分布特征,例如处于不同的大小范围,或者处于不同的幅值范围,此时可以通过不同分组的不同量化方式,来避免不同分布特征的CSI反馈信息之间做统一量化。
可选的,CSI反馈信息是基于神经网络模型生成的。示例性的,结合参考图4,终端设备侧存在一个编码端神经网络,终端设备通过CSI测量,生成待反馈信道信息,将待反馈信道信息经过编码端神经网络生成第一信道信息(即CSI反馈信息)。
可选的,终端设备在对CSI反馈信息进行分组量化后,得到量化后的CSI反馈信息,将量化后的CSI反馈信息发送给网络设备,网络设备相应接收量化后的CSI反馈信息,并根据目标分组量化方案进行解量化,得到CSI反馈信息。
综上所述,本实施例提供的方法,终端设备与网络设备之间商定目标分组量化方案,以使得终端设备基于目标分组量化方案对CSI反馈信息进行分组,按照分组对应的量化方式对CSI反馈信息进行量化,由于存在至少两个分组对应于不同的量化方式,相比于现有技术中使用的统一量化方案,这种分组量化的方法充分利用了CSI反馈信息的分布特征,对不同分布特征的CSI反馈信息通过不同分组分别进行量化,从而在保证量化精度的情况下,尽可能地降低量化所需的比特数,进而降低CSI反馈信息的反馈开销。
在基于图6的可选实施例中,终端设备与网络设备之间通过交互确定目标分组量化方案,存在如下2种不同的方案。
一、网络设备向终端设备指示一个目标分组量化方案。
二、网络设备向终端设备指示多个候选目标分组量化方案,目标分组量化方案为多个候选目标分组量化方案中的一个方案。

在第一分组对应的第一量化方式中,采用均匀量化,量化粒度是第一量化粒度,量化比特为第一量化比特,量化范围为第一量化范围。例如:第一量化粒度是1/(2^4),第一量化比特为4,第一量化范围为0至1,则第一量化方式会将0至1之间的数字通过4比特量化,并且量化粒度保持在1/(2^4)。通过上述方式可以反馈16个实数。
在第二分组对应的第二量化方式中,采用均匀量化,量化粒度是第二量化粒度,量化比特为第二量化比特,量化范围为第二量化范围。例如:第二量化粒度是1/(2^4),第二量化比特为2,第二量化范围为0至0.25,则第二量化方式会将0至0.25之间的数字通过2比特量化,并且量化粒度保持在1/(2^4)。通过上述方式可以反馈32个实数。
