Description

一种信息处理的方法和装置

技术领域
本申请实施例涉及通信领域，更具体地，涉及一种信息处理的方法和装置。
背景技术
在终端设备移动性场景下，终端设备在不同时刻的信道可能会发生剧烈变化，致使性能下降，也即“信道老化”问题。为了避免性能下降，终端设备可以联合多个时刻或多个OFDM符号的下行信道测量信息(例如，信道状态信息参考信号(channel state information reference signal，CSI-RS)、跟踪参考信号(tracking reference signal，TRS))将信道时域相关信息反馈给网络设备。信道时域相关信息能够指示信道随时间的变化或随时间的变化的快慢，网络设备会基于信道时域相关信息对下行参考信号的配置或下行预编码的方式进行相应地动态调整，从而更好地服务当前终端设备。
相关的技术方案中，终端设备在计算信道时域相关信息的过程中，未考虑终端设备的天线端口的接收方式，导致计算得到的信道时域相关信息的准确性较差，从而影响网络设备的配置或决策，降低了性能。
因此，如何提高终端设备向网络设备反馈的信道时域相关信息的准确性成为亟需要解决的技术问题。

此外，终端设备还可以包括智能打印机、火车探测器、加油站等传感器，主要功能包括收集数据(部分终端设备)、接收网络设备的控制信息与下行数据，并发送电磁波，向网络设备传输上行数据。
本申请中，用于实现终端设备的功能的装置可以是终端设备；也可以是能够支持终端设备实现该功能的装置，例如芯片系统、硬件电路、软件模块、或硬件电路加软件模块，该装置可以被安装在终端设备中或可以与终端设备匹配使用。本公开提供的技术方案中，以用于实现终端设备的功能的装置是终端设备，终端设备是UE为例，描述本公开提供的技术方案。
本申请实施例中，网络设备可以是任意一种具有无线收发功能的设备。该设备包括但不限于：演进型节点B(evolved Node B，eNB)、无线网络控制器(radio network controller，RNC)、节点B(Node B，NB)、基站控制器(base station controller，BSC)、基站收发台(base transceiver station，BTS)、家庭基站(例如，home evolved NodeB，或home Node B，HNB)、基带单元(baseband unit，BBU)，无线保真(wireless fidelity，WiFi)系统中的接入点(access point，AP)、无线中继节点、无线回传节点、传输点(transmission point，TP)或者发送接收点(transmission and reception point，TRP)等，还可以为5G，如，NR，系统中的gNB，或，传输点(TRP或TP)，5G系统中的基站的一个或一组(包括多个天线面板)天线面板，或者，还可以为构成gNB或传输点的网络节点，如基带单元(BBU)，或，分布式单元(distributed unit，DU)，或者下一代通信6G系统中的基站等。
在一些部署中，gNB可以包括集中式单元(centralized unit，CU)和DU。gNB还可以包括有源天线单元(active antenna unit，AAU)。CU实现gNB的部分功能，DU实现gNB的部分功能。比如，CU负责处理非实时协议和服务，实现无线资源控制(radio resource control，RRC)，分组数据汇聚层协议(packet data convergence protocol，PDCP)层的功能。DU负责处理物理层协议和实时服务，实现无线链路控制(radio link control，RLC)层、媒体接入控制(medium access control，MAC)层和物理(physical，PHY)层的功能。AAU实现部分物理层处理功能、射频处理及有源天线的相关功能。由于RRC层的信息最终会变成PHY层的信息，或者，由PHY层的信息转变而来，因而，在这种架构下，高层信令，如RRC层信令，也可以认为是由DU发送的，或者，由DU和CU发送的。可以理解的是，网络设备可以为包括CU节点、DU节点、AAU节点中一项或多项的设备。此外，可以将CU划分为接入网(radio access network，RAN)中的网络设备，也可以将CU划分为核心网(core network，CN)中的网络设备，本申请对此不做限定。
网络设备为小区提供服务，终端设备通过网络设备分配的传输资源(例如，频域资源，或者说，频谱资源)与小区进行通信，该小区可以属于宏基站(例如，宏eNB或宏gNB等)，也可以属于小小区(small cell)对应的基站，这里的小小区可以包括：城市小区(metro cell)、微小区(micro cell)、微微小区(pico cell)、毫微微小区(femto cell)等，这些小小区具有覆盖范围小、发射功率低的特点，适用于提供高速率的数据传输服务。

图1是适用于本申请实施例的通信方法的通信系统100的示意图。如图1所示，该通信系统100可以包括至少一个网络设备，例如图1所示的网络设备110；该通信系统100还可以包括至少一个终端设备，例如图1所示的终端设备120。网络设备110与终端设备120可通过无线链路通信。各通信设备，如网络设备110或终端设备120，均可以配置多个天线。对于该通信系统中的每一个通信设备而言，所配置的多个天线可以包括至少一个用于发送信号的发送天线和至少一个用于接收信号的接收天线。因此，该通信系统中的各通信设备之间，网络设备110与终端设备120之间，可通过多天线技术通信。
应理解，图1仅为便于理解而示例的简化示意图，该通信系统中还可以包括其他网络设备或者还可以包括其他终端设备，图1中未予以画出。
上述图1所示的本申请实施例能够应用的架构仅是一种举例说明，适用本申请实施例的架构并不局限于此，任何能够实现上述各个设备的功能的架构都适用于本申请实施例。
还应理解，上述命名仅为便于区分不同的功能而定义，不应对本申请构成任何限定。本申请并不排除在5G网络以及未来其它的网络中采用其他命名的可能。例如，在6G网络中，上述各个设备中的部分或全部可以沿用5G中的术语，也可能采用其他名称等。图1中的各个设备之间的接口名称只是一个示例，具体实现中接口的名称可能为其他的名称，本申请对此不作具体限定。此外，上述各个设备之间的所传输的消息(或信令)的名称也仅仅是一个示例，对消息本身的功能不构成任何限定。
为了提高信号传输质量或者速率，网络设备在向终端设备传输数据之前，需要对无线信道进行信道估计。网络设备可以根据来自终端设备的探测参考信号(sounding reference signal，SRS)进行信道估计，得到上行信道状态信息(channel state information，CSI)，该信道状态信息表征网络设备接收到参考信号的时刻(时刻1)的信道的状态。在时分复用(time division duplexing，TDD)系统中，无线信道的上下行具有互异性，因此在信道估计过程中，网络设备根据该上行CSI获得下行CSI，利用下行CSI计算出进行数据传输所使用的下行预编码，并使用该下行预编码(在时刻2)向终端设备传输数据。
应理解，信号通过无线信道由发射端到接收端的过程中，由于可能经历散射、反射以及能量随距离的衰减，从而产生衰落。CSI用于表征无线信道的特征，可以包括预编码矩阵指示(pre-coding matrix indicator，PMI)、信道质量指示(channel quantity indicator，CQI)、CSI-RS资源指示(CSI-RS resource indicator，CRI)、同步信号和物理广播信道块(synchronization signal and physical broadcast channel block，SSB)资源指示(SSB resource indicator，SSBRI)、层指示(layer indicator，LI)、秩指示(rank indicator，RI)、参考信号接收功率(reference signal received power，RSRP)和信号与干扰噪声比(signal to interference plus noise ratio，SINR)中的至少一种。CSI可由终端设备通过物理上行控制信道(physical uplink control channel，PUCCH)或物理上行共享信道(physical uplink share channel，PUSCH)发送给网络设备。
由于时刻1和时刻2存在时延，在终端设备移动性场景下，终端设备在时刻2的信道相比于时刻1可能已经产生了剧烈变化，导致了下行预编码与时刻2的终端设备的信道不匹配，致使性能下降，也即“信道老化”问题。
为了避免性能下降，终端设备可以联合多个时刻的下行信道测量信息(例如，信道状态信息参考信号(channel state information reference signal，CSI-RS)、跟踪参考信号(tracking reference signal，TRS))，将信道时域相关信息反馈给网络设备。一方面，网络设备可以利用时刻1的信道，时刻1之前通过若干个参考信号得到的信道，以及信道时域相关信息预测时刻2的信道，从而克服信道老化带来的性能下降问题，提升性能。另一方面，终端设备反馈的信道时域相关信息也可以帮助网络设备进行下行参考信号的配置，从而更好地服务终端设备，提升性能。
应理解，信道时域相关信息能够指示信道随时间的变化或随时间的变化的快慢，例如网络设备确定当前终端设备信道随时间变化非常快的情况下(一般来说表征该终端设备在高速移动中)，网络设备会对下行参考信号的配置或者预编码的方式或者终端设备上行反馈信道的方式进行相应地动态调整，从而更好地服务当前终端设备。
因此，为了使得网络设备更好的服务终端设备，提升性能，终端设备向网络设备上报信道时域相关信息的准确性显得尤为重要。
相关的技术方案中，通过如下公式计算信道时域相关信息。
或
其中，n表示子载波的数量；
Hn(t)表示t时刻或OFDM符号子载波的信道CSI；
Hn(t+τ)表示t+τ时刻或OFDM符号子载波的信道CSI；
A(t,τ)为信道时域相关信息，表示t时刻或OFDM符号至t+τ时刻或OFDM符号的时间段内信道随时间变化的剧烈程度。
上述计算信道时域相关信息的过程中，未考虑终端设备的天线端口的接收方式，导致计算得到的信道时域相关信息的准确性较差，从而影响网络设备对下行参考信号的配置或者预编码方式的确定或者信道预测，降低性能。
有鉴于此，本申请实施例提供了一种信息处理的方法，可以在终端设备计算信道时域相关信息的过程中，考虑了终端设备的天线端口的接收方式，从而提高信道时域相关信息的准确性。应理解，所述天线端口，也可以是端口，天线，接收端口，接收天线。
下面结合图2-图3，对本申请实施例提供的一种信息处理的方法进行详细描述。应理解，图2-图3的方法可以由终端设备执行，或者也可以由具有终端设备的功能的芯片执行。
图2是本申请实施例提供的一种信息处理的方法的示意性流程图。如图2所示，该方法可以包括步骤210-220，下面分别对步骤210-220进行详细描述。
步骤210：根据终端设备的至少两组天线端口分别确定至少两组信道时域相关信息。
本申请实施例中，可以将终端设备的多个天线端口分为至少两组，每组中可以包括至少一个天线端口。针对每一组天线端口而言，可以反馈一组信道时域相关信息，也即，针对终端设备的至少两组的天线端口，可以生成或确定至少两组信道时域相关信息，每一组信道时域相关信息和每一组天线端口一一对应。
其中，上述每组信道时域相关信息中可以包括多个T个时刻或T个正交频分复用(orthogonal frequency division multiplexing，OFDM)符号对应的M个信道时域相关信息，该M个所述信道时域相关信息用于指示该T个时刻或T个OFDM符号的信道之间的相关性。
应理解，如何对终端设备的多个天线端口进行分组(也即如何将终端设备的多个天线端口划分为上述至少两组)的方式有多种，本申请实施例对此不做具体限定。一种可能的实现方式中，可以是终端设备确定分组方式，并将该分组方式反馈给网络设备的。另一种可能的实现方式中，还可以是网络设备通知终端设备进行相应的分组。另一种可能的实现方式中，还可以是终端设备和网络设备预先确定好对终端设备的多个天线端口的分组方式。
在一些实施例中，对于每一组天线端口确定一组信道时域相关信息而言，当一组中包括大于一个天线端口的情况下，可以根据该组天线端口中包括的至少两个天线端口确定。下面会结合具体的公式进行详细描述，此处不再赘述。
步骤220：向网络设备发送所述至少两组信道时域相关信息或一组信道时域相关信息。
本申请实施例中，终端设备可以向网络设备发送上述确定的至少两组信道时域相关信息，或者还可以向网络设备发送根据所述至少两组信道时域相关信息确定的一组信道时域相关信息，本申请实施例对此不做具体限定。
一个示例，如果终端设备向网络设备发送的是一组信道时域相关信息，那么该终端设备还需要根据至少两组信道时域相关信息确定出一组信道时域相关信息。具体的实现方式有多种，一种可能的实现方式中，终端设备可以根据至少两组信道时域相关信息对应的置信度，从所述至少两组信道时域相关信息中选择一组信道时域相关信息作为所述一组信道时域相关信息。一种可能的实现方式中，终端设备可以根据至少两组信道时域相关信息对应的置信度，对所述至少两组信道时域相关信息进行加权 平均，得到所述一组信道时域相关信息。一种可能的实现的方式中，终端设备可以根据至少两组信道时域相关信息计算其算术平均得到所述一组信道时域相关信息。
另一个示例，如果终端设备向网络设备发送的是至少两组信道时域相关信息。一种可能的实现的方式中，网络设备可以根据至少两组信道时域相关信息计算其算术平均得到所述一组信道时域相关信息。该终端设备还可以向网络设备发送至少两组信道时域相关信息分别对应的至少两个置信度信息。网络设备可以根据至少两组信道时域相关信息以及对应的置信度确定出一组信道时域相关信息。具体的实现方式有多种，一种可能的实现方式中，网络设备可以根据至少两组信道时域相关信息对应的置信度，从所述至少两组信道时域相关信息中选择一组置信度最高的信道时域相关信息作为所述一组信道时域相关信息。另一种可能的实现方式中，网络设备可以根据至少两组信道时域相关信息对应的置信度，对所述至少两组信道时域相关信息进行加权平均，得到所述一组信道时域相关信息。
上述技术方案中，可以基于终端设备的至少两组天线端口分别向网络设备反馈至少两组信道时域相关信息，或根据该至少两组信天线端口确定的一组信道时域相关信息。终端设备不同的天线端口由于不同的接收信道功率或信噪比或随机相位噪声，再加上终端设备的天线端口排布位置的多样性，不同的天线端口可能会得到不同的信道时域相关信息，因此，将至少两组的天线端口对应的至少两组信道时域相关信息全部反馈给网络设备，或者将根据该至少两组信道时域相关信息确定的一组信道时域相关信息反馈给网络设备，这样，可以提高终端设备反馈给网络设备的信道时域相关信息的准确性，从而可以更准确的反映出信道随时间的变化特性。
图3是本申请实施例提供的另一种信息处理的方法的示意性流程图。如图3所示，该方法可以包括步骤310-320，下面分别对步骤310-320进行详细描述。
步骤310：根据终端设备的至少两个天线端口分别对应的信道时域相关信息确定一组信道时域相关信息。
本申请实施例中可以根据终端设备的至少两个天线端口分别对应的信道时域相关信息确定一组信道时域相关信息，该一组信道时域相关信息中包括T个时刻或T个OFDM符号分别对应的M个信道时域相关信息。每个信道时域相关信息是根据至少两个天线端口确定的，M个信道时域相关信息用于指示T个时刻或T个OFDM符号的信道之间的相关性。
步骤320：向网络设备发送一组信道时域相关信息。
终端设备在获得上述一组信道时域相关信息后，可以将该一组信道时域相关信息发送给网络设备。
上述技术方案中，终端设备向网络设备反馈的一组信道时域相关信息中的每个信道时域相关信息是根据联合平均至少两个天线端口对应的信道确定的，也即考虑了终端设备的至少两个天线端口对应的信道时域相关信息，等效于在计算每个信道时域相关信息时进行了终端设备的不同天线端口之间的平均，增加了每个信道时域相关信息计算的样本数，从而实现了对每个信道时域相关信息的计算噪声进行降噪的功能，提高了终端设备反馈给网络设备的信道时域相关信息的准确性，从而可以更准确的反映出信道随时间的变化特性。
下面以终端设备有Nr个天线端口，网络设备发送TRS或CSI-RS，终端设备可以获得总共N个子载波的信道，终端设备上报τ1,τ2,…,τM这M个时间间隔或时间差或OFDM符号间隔的信道时域相关信息(例如，时域相关系数或时域相关系数的幅度)为例，结合图4-图6，对图2-图3中所示的方法的具体实现方式进行举例说明。
应理解，图4-图6的例子仅仅是为了帮助本领域技术人员理解本申请实施例，而非要将申请实施例限制于所示例的具体数值或具体场景。本领域技术人员根据下面所给出的图4-图6的例子，显然可以进行各种等价的修改或变化，这样的修改和变化也落入本申请实施例的范围内。
一个示例，对应于步骤310，以终端设备根据该终端设备的至少两个天线端口对应的信道时域相关信息联合平均确定一组信道时域相关信息R1*M＝{R(τ1),R(τ2)，……，R(τM)}为例。其中，R1*M为一组信道时域相关信息，该组信道时域相关信息中包括M个信道时域相关信息，分别为(τM)}R(τ1),R(τ2)，……，R(τM)，τ1，τ2，……，τM为M个时间间隔或时间差或OFDM符号间隔。
例如，以R(τ1),R(τ2),…,R(τM)为时域相关系数的幅度，本申请实施例可以通过如下公式计算得到 R(τi)。
或
其中，R(τi)表示t时刻至t+τi时刻或OFDM符号t至OFDM符号t+τi的时间段内信道随时间变化的剧烈程度(信道时域相关信息)；
hk,n(t)表示终端设备的天线端口k在t时刻或OFDM符号t对应的子载波n的信道信息；
hk,n(t+τi)表示终端设备的天线端口k在t+τi时刻或OFDM符号t+τi对应的子载波n的信道信息；
考虑到终端的天线端口可能有不同的接收相位噪声，本申请实施例也可以通过如下公式进行计算：
或
又如，以R(τ1),R(τ2),…,R(τM)为时域相关系数为例，本申请实施例可以通过如下公式计算得到R(τi)。
或
应理解，上述hk,n(t)可以是终端设备通过t时刻网络设备发送的TRS或CSI-RS信号获得的，上述hk,n(t+τi)可以是终端设备通过t+τi时刻网络设备发送的TRS或CSI-RS信
号获得的。
举例说明，如图4所示，以Nr＝4为例，假设终端设备有4个天线端口，R(τ1)指示的t时刻至t+τ1时刻的时间段内信道随时间变化的剧烈程度(信道时域相关信息)，该R(τ1)是对终端设备的h1～h4的4个天线端口的信道时域相关信息进行联合平均。也即该实现方式将终端设备的不同天线端口(h1～h4)的信道向量进行了“串联”，将单端口的信道扩展为多端口的信道，从原来的N样本相关提升为N*Nr个样本求相关，等效于在计算信道时域相关信息时进行了不同天线端口间的平均，从而实现了降噪的功能。对Nr个端口进行串联，等效于信噪比(signal noise ratio，SNR)提升了δ＝10log10Nr dB。
另一个示例，对应于步骤210，以终端设备根据该终端设备的至少两组天线端口对应的信道时域相关信息确定至少两组信道时域相关信息为例。
一种情况，每组天线端口包括一个天线端口，也可以理解为将终端设备的不同天线端口的信道向量进行了“并联”。这种实现方式中，终端设备可以向网络设备反馈一个信道时域相关信息矩阵也即终端设备的每个天线端口反馈各自对应的信道时域相关信息，总共反馈Nr组信道时域相关信息。
例如，以Nr组信道时域相关信息中的每个元素rk,m为时域相关系数的幅度，本申请实施例可以通过如下公式计算得到rk,m。
或
其中，k＝1,2,…,Nr，m＝1,2,…,M。
又如，以Nr组信道时域相关信息中的每个元素rk,m为时域相关系数，本申请实施例可以通过如下公式计算得到rk,m。
或
举例说明，如图5所示，以Nr＝4为例，假设终端设备有4个天线端口，每个天线端口可以反馈一组信道时域相关信息，4个天线端口可以反馈4组信道时域相关信息。也即该实现方式将终端设备的 不同天线端口(h1～h4)的信道向量进行了“并联”，每个天线端口反馈各自对应的信道时域相关信息。
上述终端设备的天线端口并联的信道时域相关信息的反馈方式，考虑了由于终端设备的天线排布，不同的天线端口的信道可能会的得到不同的信道时域相关信息，提升了性能。
另一种情况，每组天线端口包括至少两个天线端口。假设将终端设备的多个天线端口分为G组，其中第g组包含Ng个天线端口，每组天线端口反馈一组信道时域相关信息。这种实现方式中，终端设备可以向网络设备反馈一个信道时域相关信息矩阵也即总共反馈G组信道时域相关信息。
例如，以G组信道时域相关信息中的每个元素rg,m为时域相关系数的幅度，本申请实施例可以通过如下公式计算得到rg,m。

举例说明，如图6所示，以Nr＝4,G＝2,N1＝N2＝2为例。假设终端设备有4个天线端口，将该4个天线端口分为2组，每组天线端口中包括2个天线端口(第一组天线端口中包括天线端口h1～h2，第二组天线端口中包括天线端口h3～h4)，2组天线端口可以反馈2组信道时域相关信息。对于1组内的2个天线端口而言，可以根据该2个天线端口对应的信道时域相关信息联合平均确定1组信道时域相关信息。也即该实现方式将终端设备的2组天线端口的信道向量进行了“并联”，而每一组内的2个天线端口的信道向量进行了“串联”。
需要说明的是，终端设备的多个天线端口信道“串联”的方式可以理解为是G＝1的一种特殊形式，终端设备的多个天线端口信道“并联”的方式可以理解为是G＝Nr的一种特殊形式。

一个示例，最小时间间隔或时间差或OFDM符号间隔对应最大信道时域相关信息的情况。如图7所示，一般信道时域相关信息会随着时间间隔或时间差或OFDM符号间隔增大而降低，假设τ1为最小时间间隔或时间差或OFDM符号间隔，则τ1对应的R(τ1)是R(τ1),R(τ2),…,R(τM)中最大的值。本申请实施例可以通过R(τ1)对R(τ2),…,R(τM)做进一步的归一化，得到的归一化结果为该终端设备可以向网络设备反馈R(τ1)以及归一化结果
需要说明的是，上述R(τ1)可以采用L1个比特进行量化，可以采用L2≤L1个比特进行量化。
另一个示例，最小时间间隔或时间差或OFDM符号间隔并非对应最大信道时域相关信息的情况。如图8所示，τ1为最小时间间隔或时间差或OFDM符号间隔，τ1对应的R(τ1)不是R(τ1),R(τ2),…,R(τM)中最大的值，τflag对应的R(τflag)是R(τ1),R(τ2),…,R(τM)中最大的值。本申请实施例可以通过R(τflag)对R(τ1),R(τ2),…,R(τm),…,R(τM)做进一步的归一化，得到的归一化结果为 τm≠τflag。该终端设备可以向网络设备反馈τflag＝argmaxτR(τ)以及归一化结果τm≠τflag。
需要说明的是，上述R(τflag)可以采用L1个比特进行量化，可以采用L2≤L1个比特进行量化。
下面对如何采用L个比特对R(τflag)或归一化后的进行量化的具体实现方式进行详细描述。
一种可能的实现方式中，可以采用均匀量化的方式采用L个比特对R(τflag)或归一化后进行量化。具体的，可以将[0,1]划分为或这2L个值，找到待量化的R(τflag)或归一化后与或值中最近的一个值相应地根据对应的L个比特得到其量化结果。一种可能的实现方式，是I或I-1对应的L位二进制形式作为量化后的L个比特。
另一种可能的实现方式中，可以采用非均匀量化的方式采用L个比特对R(τflag)或归一化后进行量化。具体的，可以将[0,1]划分为20,2-1,…,2-(L-1)或2-1,2-2,…,2-L这2L个值。也即找到待量化的R(τflag)或归一化后与20,2-1,…,2-(L-1)或2-1,2-2,…,2-L值中最近的一个值2-I，相应地根据2-I对应的L个比特得到其量化结果。一种可能的实现方式，一种可能的实现方式，是I或I-1对应的L位二进制形式作为量化后的L个比特。
