图2示出本申请实施例中的信道信息的上报方法的一种流程示意图,该方法200可以由终端执行。换言之,所述方法可以由安装在终端上的软件或硬件来执行。如图2所示,该方法可以包括以下步骤。
S210,终端根据第一报告配置,获取待上报的目标时域信息,其中,所 述目标时域信息用于指示多个时刻的信道变化特征。
在本申请实施例中,所述目标时域信息用于指示多个时刻的信道变化特征,例如,指示多个时刻的信道幅度和/或信道相位的变化特征。网络侧设备根据目标时域信息对信道进行预测。
在本申请实施例中,多个时刻可以为多个相邻的时隙,也可以为多个具有固定间隙的时隙,具体本申请实施例中不作限定。
可选地,所述目标时域信息包括但不限于以下至少之一:
(1)目标时域信道信息,其中,所述目标时域信道信息包括所述终端在所述多个时刻通过CSI参考信号(CSI Reference Signal,CSI-RS)获得的信道信息。
例如,目标时域信息为终端在k个时隙(slot)对CSI-RS进行信道测量的信道测量结果H=[h_1,h_2,…,h_k]。
(2)目标时域信道的相关信息,其中,所述目标时域信道的相关信息包括所述多个时刻的信道信息的特征信息。
例如,终端在k个slot对CSI-RS进行信道测量的信道测量结果为H=[h_1,h_2,…,h_k],则信道的时域自相关矩阵为H HH,其特征值分解结果为H HH=VDV H,其中V表示特征向量矩阵,每一列为一个特征向量,D表示特征向量对应的特征值构成的对角矩阵。终端可以利用网络侧设备指定或者终端选择的特征向量及其特征值构成所述目标时域信息。
(3)多普勒(doppler)域信道信息,其中,所述多普勒域信道信息包括按照预定方式对所述特征信息进行变换得到的信息。
例如,终端在k个slot对CSI-RS进行信道测量的信道测量结果为H=[h_1,h_2,…,h_k],则信道的时域自相关矩阵为H HH,其特征值分解结果为H HH=VDV H,其中V表示特征向量矩阵,每一列为一个特征向量,D表示特征向量对应的特征值构成的对角矩阵。终端对特征向量矩阵进行离散傅里叶变化(Discrete Fourier Transform,DFT),得到变换后的矩阵V’=W_d*V, 其中W_d为DFT矩阵。终端选择矩阵V’中每一列的特定的值,以及特定值对应的W_d的行向量序号(向量标识),与相应的特征值构成所述目标时域信息。
S212,终端在目标资源上上报第一报告,其中,所述第一报告中包括所述目标时域信息,所述目标资源为所述第一报告配置指示的上报资源。
在本申请实施例中,第一报告可以也周期性的,也可以半持续性的,或者也可以是非周期性。具体本申请实施例中不作限定。
通过本申请实施例提供的技术方案,终端根据第一报告配置,获取指示多个时刻的信道变化特征的目标时域信息,然后将所述目标时域信息包括在第一报告中上报,从而使得网络侧设备可以获取到多个时刻的信道变化特征,进而可以根据多个时刻的信道变化特征对所述终端进行调度,避免UE测量的CSI的时刻与基站使用该CSI进行预编码等操作的时刻信道不相干而导致***性能下降的问题。并且,网络侧设备也可以基于多个时刻的信道变化特征,对信道进行预测,提高信道预测的准确性。
在本申请实施例中,第一报告配置可以为网络侧设备为终端配置的,例如,网络侧设备通过高层参数为终端配置第一报告配置,例如,通过无线资源控制(Radio Resource Control,RRC)参数配置第一报告配置。
可选地,一个第一报告配置可以对应一个或多个第一报告。
可选地,第一报告配置中可以包括以下(1)至(4)中的至少一项信息。
(1)第一指示信息,其中,所述第一指示信息用于指示所述第一报告上报的内容信息,其中,所述内容信息包括目标时域信息。
例如,第一报告配置中可以包括一个报告内容(quantity)的参数,通过该参数的具体值来指示第一报告上报的内容信息。例如,该参数的值可以包括第一预设值,该第一预设值用于指示上报的内容信息包括所述目标时域信息。
在一种可能的实现方式中,第一报告配置可以是专用于指示终端上报所 述目标时域信息的配置,在这种情况下,可以在第一报告配置中设置报告内容(quantity)参数的值为第一预设值,指示终端上报所述目标时域信息。采用这种方式,可以减少第一报告中上报的内容,减少第一报告占用的带宽或者时频资源。
在另一种可能的实现方式中,第一报告配置也可以复用现有的CSI报告配置(CSI-ReportConfig),第一指示信息复用CSI-ReportConfig中参数reportQuantity。例如,参数reportQuantity的取值包括“DMI(多普勒矩阵指示,Doppler Matrix Indicator)”,通过DMI指示上报的内容信息包括所述目标时域信息。
在上述可能的实现方式中,可选地,所述第一指示信息指示的所述内容信息还可以包括以下至少之一:CSI-RS资源指示(CSI-RS Resource Indicator,CRI);秩指示(Rank indicator,RI);信息质量指示(Channel quality indicator,CQI);预编码矩阵指示(Precoding matrix indicator,PMI)。

(2)第二指示信息,其中,所述第二指示信息用于指示所述目标时域信息对应的频域信息。
通过第二指示信息可以指示频域配置,该频域配置与目标时域信息对应的频域信息,例如,第二指示信息指示所述目标时域信息可以通过哪些子带获取或者可以通过整个宽带获取。
例如,可以在CSI-ReportConfig中增加时域信息频域配置域,如果该频域配置域配置为wideband,则表示目标时域信息通过整个频域的信道获取,如果该频域配置域配置为subband,并通过bitmap指示具体哪些子带(对应bit为1的子带)用于获取目标时域信息。

通过码本子集限制信息可以限制第一报告上报的码本子集,以降低计算复杂度,并减少第一报告的开销。
(4)第四指示信息,其中,所述第四指示信息用于指示以下至少之一:所述目标时域信息对应的测量资源、所述目标时域信息对应的测量端口。
在该可能的实现方式中,第四指示信息可以指示使用哪些信道测量资源(Channel Measure Resource,CMR)、或者哪些信道测量资源的哪些端口、或者某个信道测量资源的哪些端口进行测量,并利用测量结果获取相应的目标时域信息。一种可能的实现方式中,所述第四指示信息可以通过组合数的方式指示一个端口组合、或者资源组合、或者端口与资源组合,或者第四指示信息还可以通过bit序列指示测量资源及测量资源端口。
在一个可能的实现方式中,在S210中,获取待上报的目标时域信息可以包括:在所述多个时刻中的每个时刻,分别对至少一个CMR进行信道测量,得到多个信道的测量结果;根据所述多个测量结果,获取所述待上报的目标时域信息。在该可能的实现方式中,终端根据在各个时刻对CMR进行信道测量得到的测量结果,获取待上报的目标时域信息。

例如,网络侧设备配置或者指示一个专用的CSI-RS set用于UE获取计算时域信息所需要的信道,终端测量CSI-RS set中的所有CMR获取多个时刻的信道测量结果,通过多个时刻的信道测量结果获取所述目标时域信息,UE不期望该CSI-RS set中的CMR具有相同的slot offset。

在上述可能的实现方式中,在所述终端设置所述特征向量不进行归一化操作或网络侧设备指示所述特征向量不进行归一化操作的情况下,所述目标时域信息中不包括所述特征值。也就是说,在上述特征向量的模值不为1,或者上述特征值归一化的情况下,目标时域信息中不包括特征值,从而可以减少开销。
在一个可能的实现方式中,在S212中,所述终端在目标资源上上报第一报告,包括:生成第一报告;在所述目标资源上,将所述第一报告映射在上行控制信息(Uplink Control Information,UCI)比特序列中。也就是说,在该可能的实现方式中,将第一报告作为UCI的一部分上报。
