具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本公开相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本公开的一些方面相一致的装置和方法的例子。
本公开实施例提供的多输入多输出模式配置方法可应用于图1所示的无线通信系统中。参阅图1所示，该无线通信系统中包括网络设备和终端。终端通过无线资源与网络设备相连接，并进行数据传输。
可以理解的是，图1所示的无线通信系统仅是进行示意性说明，无线通信系统中还可包括其它网络设备，例如还可以包括核心网设备、无线中继设备和无线回传设备等，在图1中未画出。本公开实施例对该无线通信系统中包括网络设备数量和终端数量不做限定。
进一步可以理解的是，本公开实施例无线通信系统，是一种提供无线通信功能的网络。无线通信系统可以采用不同的通信技术，例如码分多址(code division multiple access,CDMA)、宽带码分多址(wideband code division multiple access，WCDMA)、时分多址(time division multiple access，TDMA)、频分多址(frequency division multiple access，FDMA)、正交频分多址(orthogonal frequency-division multiple access，OFDMA)、单载波频分多址(single Carrier FDMA，SC-FDMA)、载波侦听多路访问/冲突避免(Carrier Sense Multiple Access with Collision Avoidance)。根据不同网络的容量、速率、时延等因素可以将网络分为2G(英文：generation)网络、3G网络、4G网络或者未来演进网络，如5G网络，5G网络也可称为是新无线网络(New Radio，NR)。为了方便描述，本公开有时会将无线通信网络简称为网络。
进一步的，本公开中涉及的网络设备也可以称为无线接入网设备。该无线接入网设备可以是：基站、演进型基站(evolved node B，基站)、家庭基站、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NR系统中的gNB，或者，还可以是构成基站的组件或一部分设备等。应理解，本公开的实施例中，对网络设备所采用的具体技术和具体设备形态不做限定。在本公开中，网络设备可以为特定的地理区域提供通信覆盖，并且可以与位于该覆盖区域(小区)内的终端进行通信。此外，当为车联网(V2X)通信系统时，网络设备还可以是车载设备。
进一步的，本公开中涉及的终端，也可以称为终端设备、用户设备(User Equipment，UE)、移动台(Mobile Station，MS)、移动终端(Mobile Terminal，MT)等，是一种向用户提供语音和/或数据连通性的设备，例如，终端可以是具有无线连接功能的手持式设备、车载设备等。目前，一些终端的举例为：智能手机(Mobile Phone)、口袋计算机(Pocket Personal Computer，PPC)、掌上电脑、个人数字助理(Personal Digital Assistant，PDA)、笔记本电脑、平板电脑、可穿戴设备、或者车载设备等。此外，当为车联网(V2X)通信 系统时，终端设备还可以是车载设备。应理解，本公开实施例对终端所采用的具体技术和具体设备形态不做限定。
相关技术中，采用MIMO技术以提高数据传输速率，并提高数据吞吐量和信噪比。MIMO是指在发射端和接收端分别使用多个发射天线和接收天线，使信号通过发射端与接收端的多个天线传送和接收，提高数据吞吐量和信噪比,从而提高系统性能改善通信质量。它能充分利用空间资源，通过多个天线实现多发多收，在不增加频谱资源和天线发射功率的情况下，可以成倍的提高系统信道容量。
MIMO技术正越来越多地被应用于多种高数据速率技术，包括WiFi，4G长期演进(Long Term Evolution，LTE)以及5G NR。MIMO系统就是多个信号流在空中的并行传输。在发射端输入的数据流变成几路并行的符号流，分别从Nt个天线同时发射出去；接收端从Nr个接收天线将信号接收下来，恢复原始信号，如图2所示。
MIMO技术中，多个信号流可以是不同的数据流，也可以是同一个数据流的不同版本。不同的数据流可以理解为是不同的信息同时发射，使信息传送效率提升，提高了无线通信的效率。同一个数据流的不同版本(同样的信息，不同的表达方式)并行发射，确保接收端收到信息的准确，提高信息传送的可靠性。其中，提高信息传送效率的工作模式，称为MIMO的复用模式。提高信息传送可靠性的工作模式，称为MIMO的分集模式。
MIMO系统的一个重要特性就是可以通过空分复用技术来提高数据传输率。而空分复用技术，就是利用空间中信号传输的差异性，从不同的多径传输中获取不同的信息，或者增强所传输的同一个信息。而多径效应下的接收和发送，与终端的天线布局有密切的关系。例如，如果两根天线布局过于接近，相关性过大，则其接收和发送的特性非常相似，则不利于体现MIMO的应用效果。
此外，为了实现MIMO，终端需要向网络设备上报自身的支持能力，同时周期性或者根据网络设备的要求进行信道测量并上报信道质量，例如CQI等。终端MIMO模式的配置是基于测量进行配置的，在信道条件发生改变是进行MIMO模式的改变。但是终端的众多因素实时变化对天线都有影响，例如终端的元器件相对位置改变，折叠造成的终端形态改变等等，实际会影响天线间的距离和不相关性，从而影响MIMO效果。如何能在终端形态变化的情况下，快速应对形态对MIMO的影响，是本公开实施例要优化的问题。
本公开提供一种MIMO模式配置方法，在终端自身因素发生改变并触发MIMO模式调整时，直接触发MIMO模式进行调整，使信道测量与反馈等行为相应改变，进而降低MIMO配置的调整时间。
图3是根据一示例性实施例示出的一种MIMO模式配置方法的流程图，如图3所示，MIMO模式调整方法用于终端中，包括以下步骤。
在步骤S11中，确定触发因素，触发因素包括触发MIMO模式调整的终端信息。
本公开实施例中，触发因素是指能够触发MIMO模式调整的终端信息，例如触发因素包括终端器件相对位置信息和终端形态信息中的一种或多种。其中，终端器件相对位置信息可以理解为是终端的组成器件的相对位置信息，此因素会影响MIMO天线器件的遮挡条件。例如但不限于伸缩式摄像头的弹出情况，在缩回和伸出时对附近MIMO天线的遮挡情况会不同。终端形态信息可以理解为是终端的形态，例如，终端处于展开状态或是折叠状态，不同的折叠角度会影响MIMO天线间的距离、角度和相对位置，从而对天线隔离度产生影响。
其中，终端的触发因素一方面可以基于预配置信息确定的。或者另一方面，终端的触发因素也可以基于广播信令、无线资源控制(Radio Resource Control，RRC)上层配置信令或者物理层控制信令确定。
在步骤S12中，发送第一指令，第一指令用于请求网络设备为终端配置与触发因素匹配的MIMO模式。
本公开实施例中，终端确定了触发MIMO模式调整的触发因素后，向网络设备发送第一指令，以请求网络设备为终端配置与触发因素匹配的MIMO模式。
其中，触发MIMO模式调整的触发因素可以承载在上行控制信令或者上行RRC配置信令，终端基于上行控制信令或者上行RRC配置信令，发送第一指令。
在步骤S13中，获取第二指令，第二指令用于表征网络设备为终端配置的MIMO模式。
本公开实施例中网络设备接收第一指令，并为终端配置与触发因素匹配的MIMO模式，发送用于指示配置MIMO模式的第二指令，以向终端指示与触发因素匹配的MIMO模式。
图4是根据一示例性实施例示出的一种MIMO模式配置方法的流程图，如图4所示，MIMO模式调整方法用于网络设备中，包括以下步骤。
在步骤S21中，接收第一指令，第一指令用于请求网络设备为终端配置与触发因素匹配的MIMO模式，触发因素包括触发MIMO模式调整的终端信息。
在步骤S22中，为终端配置与触发因素匹配的MIMO模式。
在步骤S23中，发送第二指令，第二指令用于指示网络设备为终端配置的MIMO模式。
本公开实施例中，终端确定触发MIMO模式调整的触发因素，并向网络设备发送第一 指令请求网络设备为终端配置与触发因素匹配的MIMO模式。网络设备为终端配置与触发因素匹配的MIMO模式，并向终端发送第二指令以指示与触发因素匹配的MIMO模式。终端获取第二指令并确定网络设备为终端配置的与触发因素匹配的MIMO模式，相对基于测量进行MIMO模式调整，能够降低MIMO模式调整的时间。
本公开实施例以下结合实际应用对上述实施例涉及的MIMO模式配置方式进行说明。
一种实施方式中，本公开实施例中设置终端发送第一指令的触发条件，在终端确定的触发因素满足触发条件时，发送第一指令。
进一步的，本公开实施例设置触发因素与MIMO模式的对应关系，终端确定了触发因素后，网络设备依据触发因素与MIMO模式的对应关系确定与触发因素匹配的MIMO模式。
本公开实施例中触发因素具有不同状态，例如，触发因素为终端形态时，不同终端形态对应不同的状态。比如，终端处于展开状态对应第一状态，终端处于折叠状态对应第二状态。触发因素为终端器件相对位置信息时，终端器件不同位置对应不同的状态。比如，终端伸缩式摄像头在缩回时对应第三状态，终端伸缩式摄像头在弹出时对应第四状态。
本公开一实施方式中，针对触发因素对应的不同状态进行量化，使不同状态对应不同的状态量化值，且不同状态量化值对应不同的MIMO模式。
本公开实施例中针对触发因素对应的不同状态进行量化时，可以根据不同触发因素设置不同的量化状态。一示例中，本公开实施例中基于触发因素的绝对状态进行量化，以下将触发因素的绝对状态进行量化后的状态称为第一量化状态。其中，第一量化状态表征触发因素的绝对状态，也可称为拜耳状态。例如，第一量化状态可以是终端伸缩式摄像头的伸出状态和缩回状态，终端是否处于折叠状态。一种实施方式中，第一量化状态对应有多个不同的第一量化状态值，其中，多个不同的第一量化状态值表征触发因素多个不同的绝对状态。例如，用1比特的不同比特值(0和1)表征终端伸缩式摄像头弹出与否，或者终端处于折叠状态与否。再或者用2比特的不同比特值(00、01、10、11)表征终端的4个不同的形态状态。
另一示例中，本公开实施例中基于触发因素的相对状态进行量化，以下将触发因素的相对状态进行量化后的状态称为第二量化状态。其中，第二量化状态表征触发因素的相对状态。例如，第二量化状态可以是终端的形态信息等可以进行量化的量。本公开实施例中，第二量化状态对应有多个不同的第二量化状态值，多个不同的第二量化状态值表征触发因素多个不同的相对状态。比如，折叠屏手机的折叠角度可以量化为不同的第二量化状态值。
本公开实施例中，触发因素当前状态的状态量化值包括第一量化状态值，或者第二量化状态值，或者基于第一量化状态值和第二量化状态值确定的第一综合量化状态值。
一示例中，基于第一量化状态值和第二量化状态值确定的第一综合量化状态值可以是第一量化状态值和第二量化状态值进行运算后得到的数值。比如，第一综合量化状态值＝第一量化状态值*第二量化状态值，或者第一综合量化状态值＝第一量化状态值*a+第二量化状态值*b。其中，a和b为指定系数。
本公开实施例中触发因素当前状态的状态量化值还包括第二综合量化状态值。其中，第二综合量化状态值基于第一综合量化状态值和信道测量信息确定。第二综合量化状态值也可以理解为是第一量化状态值、第二量化状态值、第一综合量化状态值与信道测量信息进行运算后的综合值。例如，本公开实施例中，第二综合量化状态值＝f(第一综合量化状态值,信道测量信息)。其中，f函数可以是线性加权，例如第二综合量化状态值＝c*第一综合量化状态值+d*信道测量信息，其中，c和d为指定系数。或者f函数可以是对信道测量信息进行加权偏移，例如第二综合量化状态值＝第一综合量化状态值*信道测量信息。总之，第二综合量化状态值可以是表征终端信息对信道测量信息的一种额外影响。
本公开实施例中触发因素不同状态的状态量化值对应不同的MIMO模式。比如终端的伸缩式摄像头弹出状态对应的状态量化值“0”，对应MIMO模式为2*2。终端的伸缩式摄像头未弹出状态对应的状态量化值“1”，对应MIMO模式为4*4。再比如，具有折叠屏的终端折叠屏完全展开的状态对应的状态量化值“00”，对应MIMO模式为4*4。具有折叠屏的终端折叠屏完全折叠的状态对应的状态量化值“11”，对应MIMO模式为更高阶的MIMO模式，例如8x4的MIMO模式，或者至少高于上一个MIMO模式。可以理解的是触发因素状态的状态量化值对应的MIMO模式根据实际情况进行设定。比如，终端伸缩式摄像头弹出的摄像头模组带有毫米波天线模块，弹出后能够支持4*4MIMO模式，而未弹出时反而不能支持MIMO。
本公开实施例中，网络设备或终端可以基于终端触发因素当前状态的状态量化值确定需要配置的MIMO模式。
本公开实施例中终端向网络设备发送第一指令的触发条件，可以是MIMO模式调整的状态量化阈值，在触发因素当前状态的状态量化值满足触发MIMO模式调整的状态量化阈值时，发送第一指令。
进一步的，本公开实施例中终端请求网络设备配置与当前状态的状态量化值匹配的MIMO模式时，可以是直接向网络设备请求与触发因素当前状态的状态量化值匹配的 MIMO模式，也可以是终端向网络设备发送触发因素当前状态的状态量化值，由网络设备确定与触发因素当前状态的状态量化值匹配的MIMO模式。
一种实施方式中，终端向网络设备发送的第一指令中包括与触发因素当前状态的状态量化值匹配的MIMO模式。网络设备接收到第一指令后，将与触发因素当前状态的状态量化值匹配的MIMO模式，确定为终端配置的与触发因素匹配的MIMO模式。比如，当伸缩式摄像头弹出时，回退到2*2MIMO模式，第一指令中包括2*2MIMO模式。或者，当折叠屏折叠角度超过90度后，由4*4MIMO模式回退到2*2MIMO模式，第一指令中包括2*2MIMO模式。或者当伸缩式摄像头缩回，且折叠屏折叠角度超过90度时，由4*4MIMO模式回退到2*2MIMO模式，第一指令中包括2*2MIMO模式。
另一种实施方式中，终端向网络设备发送的第一指令中包括触发因素当前状态的状态量化值。网络设备基于触发因素当前状态的状态量化值，确定与触发因素当前状态的状态量化值匹配的MIMO模式，并将与触发因素当前状态的状态量化值匹配的MIMO模式，确定为为终端配置的与触发因素匹配的MIMO模式。例如，第一指令中包括第一量化状态值、第二量化状态值、第一综合量化值和第二综合量化值中的一个或多个。网络设备基于第一指令中包括的当前状态的状态量化值，确定是否进行MIMO模式改变，并确定配置的MIMO模式发送给终端。
本公开实施例又一种实施方式中，触发因素当前状态的状态量化值与MIMO模式调整阶数之间具有对应关系，则终端可以向网络设备发送MIMO模式调整阶数偏移量，由网络设备确定与触发因素当前状态的状态量化值匹配的MIMO模式。即，第一指令中包括MIMO模式调整阶数偏移量。网络设备为终端配置与触发因素匹配的MIMO模式时，基于MIMO模式调整阶数偏移量和MIMO模式当前阶数，确定为终端配置的与触发因素匹配的MIMO模式。比如，终端触发因素的状态量化值包括“00、01、10、11”，则第一指令中可以包括用于指示终端触发因素的状态量化值由“00”变为“01”的信息。
应用本公开实施例提供的MIMO模式配置方法，可以在终端上设置默认的MIMO模式，然后在终端自身因素发生改变时，依据终端的当前形态确定对应的触发因素，并进行MIMO模式的调整，例如对MIMO模式逐级调整等。
本公开实施例提供的MIMO模式配置方法，在终端自身因素发生改变并触发MIMO模式调整时，直接触发MIMO模式进行调整，使信道测量与反馈等行为相应改变，进而降低MIMO配置的调整时间。
基于相同的构思，本公开实施例还提供一种多输入多输出模式配置装置。
可以理解的是，本公开实施例提供的多输入多输出模式配置装置为了实现上述功能，其包含了执行各个功能相应的硬件结构和/或软件模块。结合本公开实施例中所公开的各示例的单元及算法步骤，本公开实施例能够以硬件或硬件和计算机软件的结合形式来实现。某个功能究竟以硬件还是计算机软件驱动硬件的方式来执行，取决于技术方案的特定应用和设计约束条件。本领域技术人员可以对每个特定的应用来使用不同的方法来实现所描述的功能，但是这种实现不应认为超出本公开实施例的技术方案的范围。
