Description

一种极化信息确定方法及其相关设备 技术领域
本申请涉及通信领域，尤其涉及一种极化信息确定方法及其相关设备。
背景技术
无线通信技术包括无线接入，以传统的点到点微波通信举例，发射机(transmitter，TX)与接收机(receiver，RX)之间的无线通信链路如果没有障碍物阻挡，则称这种链路为视距(line of sight，LOS)链路，相应的无线通信即为LOS通信，反之，发射机与接收机之间的无线通信链路如果有障碍物阻挡，则称这种链路为非视距(non-line of sight，NLOS)链路，相应的无线通信即为NLOS通信。在非视距通信中，由于障碍物的阻挡，无线电磁波的传输一般通过反射、衍射、透射等方式进行传输，传输存在损耗，从而劣化了信道条件，主要表现为RX端的接收电平(receive signal lever，RSL)降低，传输容量减小，如果RSL降低到RX的接收灵敏度以下，则该无线通信视为中断。在当前的信息化时代，基于无线通信链路，随时随地的进行无线接入已经成为通信的基本特性，因此如何降低NLOS链路的透射、反射等现象带来的信道损耗引起了社会的广泛关注。
极化图案和方向是无线电磁波的基本属性，是指电磁波的能量分布大小和方向。在LOS链路中，TX端发射的极化方向就是RX端接收的极化方向，两端天线的极化方向一致，基本不会影响RSL，而在NLOS场景中，TX端的极化电磁波经过反射、衍射、透射等，极化的图案和方向会发生变化，因此电磁波的电场强度和方向都会发生变化，导致RX端无法以信号劣化程度最小的方式接收到TX端发射的电磁波，造成接收信号的劣化。现有一种双极化架构的无线设备(比如HV极化或正负45度极化)，两个极化信道隔离度在40db以上，可以看作两个完全独立的通道，当一个极化的信道严重恶劣后另一个极化的信道还可以正常工作，起到保护作用，因此RX采用双极化架构可以接收任意极化形状和方向的电磁波，信号的RSL最多劣化3db。除TX端与RX端无法最优匹配带来的能量损耗外，障碍物的散射或透射等物理因素等本身也会带来极化的损耗影响RSL，对于同一透射场景(障碍物位置、发射设备、入射角度均固定)，不同的极化形状或极化方向，经过上述障碍物的散射和透射后，能量损耗也是不一样的，信号RSL的减小值甚至可能达到30db以上，而这个损耗是事先无法预料的。
在NLOS中，双极化架构基本可以解决极化图案和方向改变带来的接收信号的RSL损耗，但是由于TX极化形状或方向不同，经过障碍本身的散射或透射后带来的能量损耗是不同的，因此接收信号的劣化程度也是不同的，而这个损耗是事先无法预料的，某些极化方向的电磁波的能量损耗仍然可能是巨大的，因此现有的双极化架构TX端发射的电磁波经过NLOS信道传输后带来的能量损耗及其对应的接收信号的劣化程度仍然可能很大。
发明内容
本申请实施例提供了一种极化信息确定方法及其相关设备，用于解决TX端发射电磁波极化形状和极化方向不同，从而造成信号能量损耗不同的问题。
本申请实施例的第一方面提供了一种极化信息确定方法，其特征在于，包括：
接收设备接收发射设备发送的第一极化信息集合，该第一极化信息集合是由发射设备遍历极化配置图中的极化状态得到的，极化配置图包含多种极化状态(极化形状和极化方向)，发射设备按照极化配置图设置极化状态。
接收设备接收第一极化信息集合的方式是，发射设备每切换一次极化状态，就发送最新的第一极化信息给接收设备，直至遍历完成，因此接收设备收到的第一极化信息是一个集合，该集合中包括至少一个第一极化信息。
发射设备的极化信息不断切换，对应的接收信号的质量也在不断变化，该接收信号为所述发射设备通过非视距NLOS信道发送至所述接收设备的信号，每种第一极化信息都有唯一对应的接收信号质量，因为第一极化信息是一个集合，因此接收信号质量也是个集合。
接收设备需要确定接收信号的质量集合，该质量集合包括至少一个质量；
随后，接收设备确定质量集合中的最优质量，在本实施例中，所述最优质量为质量集合中使所述接收信号劣化程度最小的质量；
接收设备确定出最优质量后，反推该最优质量对应的第一极化信息，并把该第一极化信息至发射设备。
本申请实施例具有以下优点：当非视距NLOS信道发生变化时，接收设备接收发射设备发送的第一极化信息集合后，根据第一极化信息集合确定接收信号的第一质量集合，其中，第一极化信息集合中的第一极化信息和第一质量集合中的第一质量一一对应，接收设备确定第一质量集合中的第一最优质量，其中该第一最优质量为第一质量集合中信号劣化程度最小时，接收信号对应的质量，随后接收设备发送与第一最优质量对应的第一最优极化信息至发射设备，该第一最优极化信息用于发射设备确定发射电磁波的极化形状和极化方向。因此相比于现有技术中，发射电磁波按照某一极化信息进行电磁波发射后，带来的能量损耗大小未知，从而导致信号道劣化情况未知的状况，本申请无论NLOS信道如何变化，接收设备都能从接收信号的第一质量集合中选择第一最优质量，从而再确定与第一最优质量确定对应的第一最优极化信息，第一最优极化信息用于确定发射电磁波的极化，接收信号的第一质量能够反映接收信号的优劣情况，因此发射设备只需要按照第一最优极化信息进行电磁波的发射，此时接收信号的劣化程度就是最小的，进而使得由于不同的TX端的发射极化方向和极化形状，NLOS信道透射、散射等物理因素带来的信号损耗达到最低。
基于第一方面，在本申请第一方面的第一种实施方式中，其特征在于，所述接收设备接收发射设备发送的第一极化信息集合之后，所述方法还包括：
接收设备确定第二极化信息集合，第二极化信息包括极化形状和极化方向，接收设备可以根据第二极化信息设置接收设备的极化状态。
每个第一极化信息对应唯一的第二极化信息，由于第一极化信息是一个集合，因此第二极化信息也是一个集合。
在本实施例中，当接收设备采用双极化天线时，接收设备可以适配任意第一极化信息的发射电磁波，当接收设备采用全极化天线时，接收设备的极化状态也需要随着发射设备第一极化信息改变而发生改变，以达到与发射设备极化状态的匹配，本实施例通过对全极 化天线的这种情况进行介绍，增加了方案实施的多样性。
基于第一方面的第一种实施方式，在本申请实施例第一方面的第二种实施方式中，其特征在于，当所述发射设备的极化信息为所述第一极化信息时，接收设备需要确定出与该第一极化信息对应的第二极化信息，具体确定的方式为：接收设备从第三极化信息集合中确定使所述接收信号劣化程度最小的极化信息，该极化信息即为我们所需要的第二极化信息。
需要说明的是，该第三极化信息集合包括至少一个第三极化信息，所述第三极化信息包括极化形状和极化方向。
在本实施例中，对第二极化信息的确定方式进行了说明，可见第二极化信息与第一极化信息可以最佳适配，使得由于发射设备极化状态与接收设备极化状态不适配而导致的能量损耗降至最低甚至消除。
基于第一方面的第一种或第二种实施方式，在本申请第一方面的第三种实施方式中，其特征在于，所述接收设备确定所述质量集合中的最优质量之后，所述方法还包括：
所述接收设备可以根据与所述最优质量对应的所述第二极化信息控制所述接收设备的极化形状和极化方向。
在本实施例中，对与最优质量对应的第二极化信息的作用进行了说明，增加了方案的完整性。
基于第一方面及其第一方面的第一种或第二种实施方式，在本申请实施例第一方面的第四种实施方式中，其特征在于，所述接收设备确定接收信号的质量集合包括：
接收设备对接收信号进行检测；
接收设备可以根据检测结果确定与每个第一极化信息对应的接收信号的质量；
在本实施例中，对接收信号质量集合的确定方式进行了说明，增加了方案的可实施性。
基于第一方面及其第一方面的第一种或第二种实施方式，在本申请实施例第一方面的第五种实施方式中，其特征在于，所述质量为所述接收信号的接收电平功率RSL、信噪比SNR和信号干扰噪声比SINR中的至少一个。
在本实施例中，对接收信号指令的具体参数进行了说明，增加了方案的实用性。
基于第一方面及其第一方面的第一种或第二种实施方式，在本申请实施例第一方面的第六种实施方式中，其特征在于，所述方法还包括：
当所述接收信号的劣化程度高于预置门限值时，所述接收设备触发接收发射设备发送的第一极化信息集合的步骤；
或，
当预置的时间周期到达后，所述接收设备触发接收发射设备发送的第一极化信息集合的步骤。
本实施例对发射设备执行接收第一极化信息集合的条件进行了说明，增加了方案的可实施性和灵活性。
本申请实施例的第二方面提供了一种极化信息确定方法，其特征在于，包括：
所述发射设备生成第一极化信息集合，发射设备每切换一次极化状态，就发送最新的 第一极化信息给接收设备，直至遍历完成，接收设备也就收到了第一极化信息集合，所述第一极化信息集合包括至少一个第一极化信息；
发射设备的极化信息不断切换，对应的接收信号的质量也在不断变化，该接收信号为所述发射设备通过非视距NLOS信道发送至所述接收设备的信号，每种第一极化信息都有唯一对应的接收信号质量，因为第一极化信息是一个集合，因此接收信号质量也是个集合。接收信号的质量集合由接收设备根据第一极化信息集合确定。
发射设备接收接收设备发送的第一最优极化信息，其中，所述第一最优极化信息属于所述第一极化信息集合，所述第一最优极化信息与所述最优质量对应，所述最优质量由接收设备确定，该最优质量的确定方式具体为：接收设备对每种第一极化信息对应的接收信号进行检测，确定出信号劣化程度最小的接收信号，该信号劣化程度最小的接收信号的质量即为质量集合中的最优质量。
发射设备可以将发射电磁波的极化形状和极化状态设置为第一最优极化信息对应的极化形状和极化状态。
本申请无论NLOS信道如何变化，发射设备通过向接收设备发送第一极化信息集合，从而使得接收设备确定与第一极化信息集合对应的接收信号质量集合，接收设备再确定出信号劣化程度最小的质量，并将该信号劣化程度最小的质量对应的第一最优极化信息发送的发射设备，因此发射设备只需要按照第一最优极化信息进行电磁波的发射，此时接收信号的劣化程度就是最小的，进而使得由于不同的TX端的发射极化方向或形状，NLOS信道透射、散射等物理因素带来的信号损耗达到最低。
基于第二方面，在本申请第二方面的第一种实现方式中，其特征在于，
随路控制通道的控制信道的控制通道与数据通道走的同一物理信道，因此发射设备通过随路控制通道的控制信息携带第一极化信息集合后，再发送控制信息至接收设备，就可以实现接收设备与发射设备间信息的传递。
或，
旁路控制信道的控制通道与数据通道走不同的物理信道，发射设备通过旁路控制通道发送所述第一极化信息至所述接收设备，接收设备收到数据流后，不能确定出哪一条数据流携带了第一极化信息，因此需要将数据流与所述第一极化信息进行匹配，从而再根据所述数据流和匹配结果确定所述第一极化信息，直至完成所述第一极化信息集合中所有第一极化信息的确定。
在本实施例中，对第一极化信息集合的传递方式进行了具体说明，增加了方案的可实施性。
基于第二方面及其第一方面的第一种实现方式，在本申请第二方面的第二种实现方式中，其特征在于，所述方法还包括：
当所述接收信号的劣化程度高于预置门限值时，所述发射设备触发生成第一极化信息集合的步骤；

如图1所示，为NLOS信道中电磁波传播的示意图，左侧TX设备发送的无线电磁波进入无法预知的NLOS信道，图中用X棵树(X≥1，且X为正整数)表示实际生活中的NLOS信道，无线电磁波在NLOS信道中传输，经过散射、多重反射、透射等被右侧RX设备接收。其中，TX设备通过对自身天线进行控制发射电磁波，这个电磁波具有一种极化状态，称之为发射端极化状态(TX-POL，transmitter polarization)，经过NLOS信道后，生成透射波并具有另一种极化状态，称之为转换波极化状态(PT-POL，particular transfer polarization)，透射波到达RX端，RX端以一种新的极化状态接收透射波，称之为接收端极化状态(RX-POL，receiver polarization)。其中，极化状态为TX-POL的电磁波，经过NLOS信道后的能量损耗可能有两个：1、PT-POL与RX-POL不能最优匹配，导致发射的电磁波不能被RX以能量损耗最小的方式接收到。2、不同的TX-POL的电磁波，经过NLOS信道后，由于NLOS信道的透射、折射等物理因素，带来能量损耗不同的缺陷，且这个物理缺陷是不可避免的。第一个缺陷可以通过对RX-POL的控制降低甚至消除能量损耗，本申请实施例主要针对第二个缺陷提出解决方案。
极化配置方式的一种可能的情况如下图2所示，其中，圆极化的极化方向在±180°周期性匀速转动，每个方向电场强度固定，椭圆极化的极化方向在±180°周期性匀速转动，每个方向电场强度不固定但有规律。圆极化可以看成是一个长轴短轴等长的特殊椭圆极化，而线极化可以看成是短轴接近于0的特殊椭圆极化，可见，接收设备或发射设备在极化遍历的过程中，可以在圆极化、椭圆极化和线极化之间自由切换遍历。
在本申请实施例中，第一极化信息集合是发射设备对极化配置图中的极化信息进行整体或部分遍历后形成的集合，第三极化信息集合可以是极化配置图的全部极化信息，也可以是极化配置图的部分极化信息，第二极化信息集合为接收设备对第三极化信息集合进行N次遍历后形成的，N的取值范围为大于或等于1的正整数，N的取值由第一极化信息集合中第一极化信息的个数确定，具体在后续进行介绍。
需要说明的是，发射设备对极化配置图的遍历可以从极化配置图的任意一个极化信息开始，同样的可以在任意一个极化信息结束。
现有的NLOS信道中，由于发射设备按照不同极化方向和极化形状发射的电磁波，经过障碍物透射或折射后的能量损耗都是不一样的，因此本申请提出了一种极化信息确定方法，旨在找到使发射设备按照最佳方式发射的极化形状和极化方向，减少NLOS信道的物理损耗。请参照图3，下面将进行说明。
301、接收设备接收发射设备发送的第一极化信息集合。
发射设备按照极化配置图设置发射电磁波的极化信息，直至对极化配置图中的极化信息执行完一次遍历，触发发射设备执行一次遍历可以采用定时触发的方式，例如每10min发射设备遍历一次，定时触发的具体时长此处不做限定。发射设备每改变一次极化信息，接收设备都需要接收最新的第一极化信息，一次遍历完成后，发射设备暂时停止极化信息的切换，接收设备收到的所有第一极化信息即为第一极化信息集合。其中，第一极化信息包括极化形状和极化方向，发射设备将该第一极化信息中包含的极化形状和极化方向设置为发射电磁波的极化形状和极化方向，依次进行遍历。
发射设备按照极化配置表进行极化遍历时，可以以1度为一个步长设置极化状态，例如以30度线极化、31度线极化、32度线极化的极化方式进行遍历，也可以以5度为一个步长设置极化状态，极化遍历的具体步长此处不做限定。
例如，第一极化信息集合包含的极化信息有，30度线极化、60度线极化、左旋圆极化和右旋椭圆极化等，则发射电磁波分别按照30度线极化、60度线极化、左旋圆极化和右旋椭圆极化的方式进行发射。
302、接收设备确定接收信号的质量集合。
发射端的按照第一极化信息发射电磁波，如图1所示，树木的折射透射情况是未知的，也必然带来能量损耗，发射端按照第一极化信息发射，对应的极化状态用TX-POL表示，TX-POL经过NLOS信道后发生折射、透射等变成PT-POL的极化状态，此时接收端需要设置成RX-POL的极化状态与PT-POL进行匹配，由于不同的TX-POL经过NLOS信道后能量损耗不同，因此透射后的PT-POL也不同，因此本申请实施例旨在找到最佳的TX-POL使得能量损耗最小。
在本申请实施例中，极化信息和极化状态都是指电磁波的极化形状和极化方向，例如第一极化信息为左旋椭圆极化，对应的极化状态也是左旋椭圆极化。
由于每个第一极化信息带来的能量损耗不一样，经过NLOS信道后，接收信号的质量也会产生一次变化，因此每个第一极化信息都有唯一对应的接收信号的质量，接收信号的质量也是一个集合。接收信号的质量由接收端确定，可以是接收设备对接收信号的参数进行监测后确定得到，代表接收信号质量的参数可以是接收电平功率RSL、信噪比(signal noise ratio，SNR)和信号干扰噪声比(signal interference noise ratio，SINR)中的任意一个或多个的组合，具体此处不作限定。
在本实施例中，第一极化信息与接收信号质量的唯一对应关系有如下两种可能的情况，具体为：
1、第一极化信息与接收信号的质量一一对应，即一个第一极化信息对应唯一的接收信号质量；
2、至少两个第一极化信息对应相同的接收信号的质量。
303、接收设备确定质量集合中的最优质量。
接收设备在确定的接收信号的质量集合中确定出接收信号劣化程度最小的质量即为接收信号的最优质量，接收信号的劣化程度最小也可理解为发射端发射的极化状态为TX-POL的电磁波，经NLOS信道传输后，电磁波的能量损耗最小，例如分别以30度线极化和60度线极化发射的电磁波经NLOS信号传输后，能量损耗分别为10db和15db，可见30度线极化发射的电磁波能量损耗最小，因此30度线极化发射的电磁波相应的接收信号质量劣化程度最小。
最优质量是接收信号劣化程度最小的质量，具体可以理解为以下几种情况：
一、从信号参数值的角度评价接收信号质量。
1、对接收信号质量的评定只涉及一个参数，该参数可以为RSL、SNR或SINR，该参数也可以为接收信号的其他物理量，具体此处不做限定。
接收信号的最优质量可以理解为：RSL、SNR或SINR中的最大值。
2、对接收信号质量的评定只涉及两个或两个以上参数，该参数可以为RSL、SNR和SINR，该参数也可以为接收信号的其他物理量，具体此处不做限定。
接收信号的质量可以理解为：RSL、SNR或SINR中的任意两个的值与其所在的权重系数的和，接收信号的最优质量即为和最大的接收信号，例如接收信号的质量用RSL、SNR来衡量，RSL、SNR的值分别为x，y，权重系数分别为2/5、3/5，则接收信号质量为：2/5x+3/5y。
接收信号的质量也可以理解为：RSL、SNR和SINR值与三者所占的权重系数的和，接收信号的最优质量即为和最大的接收信号。
二、从信号可靠性的角度评价接收信号质量。
在本实施例中，发射设备为某一第一极化信息时，接收设备可能对接收信号的RSL进行多次检测，并判断有效RSL的次数(即RSL的值大于第一门限)，如果有效RSL占总RSL的比例越大，且，RSL的值越大，说明挺好稳定性越好，因此接收信号质量也就越好。
一种可能的情况是，接收信号质量低于第二门限时，RX端不能收到有效的接收信号， 此时接收信号质量可以近似为0，由于接收信号不能被接收设备接收，此时发射设备发送的第一极化信息接收设备自动排除。
在本实施例，最优质量的确定除了上述情况外还可能包括更多的可能，具体此处不作限定。
304、接收设备发送与最优质量对应的第一极化信息至发射设备。
接收设备接收第一极化信息集合，并确定出每个第一极化信息对应的接收信号质量后，可以形成一张极化信息与质量的对应表，接收设备明确最优质量后再反推最优质量对应的第一极化信息，并将这个第一极化信息发送给发射设备，使得发射设备按照该第一极化信息发射电磁波，此时接收信号的质量必然是最优的，以此来降低NLOS信道带来的能量损耗或信号劣化。
一种可能的情况是，与最优质量对应的第一极化信息有两个或两个以上时，接收设备可以发送与最优质量对应的第一极化信息中的任意一个第一极化信息至发射设备。
在本申请实施例中，接收设备通过接收发射设备遍历的第一极化信息集合后，确定出与第一极化信息集合对应的接收信号质量集合，从而确定出哪一个第一极化信息使得接收信号劣化程度最小，此时只需要让发射设备按照该第一极化信息进行发射，就能使得NLOS信道的折射、透射等现象带来的损耗降至最低，在无线通信中，有利用降低信号劣化程度，提升用户体验。
本申请实施例可应用于信道情况不断变化的场景，在NLOS信道情况发生变化时，发射设备通过执行图3所示实施例的步骤，总能确定出使信号质量最优的第一极化信息发送给接收设备。
在本应用场景中，NLOS信道发生变化可能会导致接收信号劣化，当接收信号劣化程度过高，大于预置的门限值时，触发接收设备执行图3所示实施例的步骤。还有一种可能的情况是采用定时触发方式，接收设备在预置时间达到后触发执行图3所示实施例的步骤。也可以同时采用定时触发和信号劣化触发，具体此处不作限定。
在本申请实施例中，由于发射端按照极化配置图不断在切换第一极化信息，因此发射端的极化状态TX-POL是不断改变的，PT-POL也不断改变，从而接收端的极化状态RX-POL需要不断变化与PT-POL进行匹配，在本申请实施例中，当采用双极化天线时，RX端可以接收任意极化形状和方向的电磁波，即无论PT-POL如何改变，都能被RX端最优接收，因此RX端不需要切换极化状态，此时信号的RSL最多劣化3db。当接收端为全极化天线时，这种天线的特点在于，随着TX端接收状态变化，RX端需要产生相应的变化，以达到PT-POL与RX-POL的最优匹配，可以降低甚至消除全极化天线中所描述的3db的RSL这一缺陷，这种情况下，RX端的极化状态也在不断地进行切换，请参照图4，下面将进行说明：
401、接收设备接收发射设备发送的第一极化信息集合。
在本实施例中，接收设备接收发射设备发送的第一极化信息集合的方式与实施例步骤301类似，具体此处不再赘述。
402、接收设备确定第二极化信息集合。
接收设备每接收一次第一极化信息，接收设备自身都需要切换一次极化信息以改变极化状态，因此接收设备需要确定出与第一极化信息对应的第二极化信息，从而按照第二极化信息进行切换。
进一步的，接收设备确定第二极化信息包括：
A、接收设备遍历第三极化信息集合。
发射设备的极化信息为第一极化信息，相当于TX-POL不变，此时RX-POL未知，RX-POL不同，PT-POL与RX-POL的匹配是不同的，能量损耗也不同，因此接收信号劣化程度也有所区别，此时接收信号的劣化不是由于NLOS信道的折射、透射等物理因素带来的，而是由于RX-POL无法与PT-POL最优匹配带来的。
为使PT-POL与RX-POL最优匹配，接收设备接收此极化信息后，需要对第三极化信息集合进行遍历。
B、接收设备确定第三极化信息集合中使接收信号劣化程度最小的极化信息。
接收设备遍历第三极化信息集合，即在发射设备极化状态不变的情况为，接收设备将RX-POL按照第三极化信息不断切换，此时接收信号质量也是不断改变的，接收设备需要找出使接收信号劣化程度最小的第三极化信息。
C、接收设备确定使接收信号劣化程度最小的极化信息为第二极化信息。
接收设备确定使接收信号劣化程度最小的极化信息为所需要的第二极化信息。
随后，发射设备切换第一极化信息，直至完成极化配置图中极化信息的全部或部分遍历，接收设备重复执行步骤A、B和C，直至确定出第二极化信息集合。
可见在本实施例中，第二极化信息与第一极化信息也具有如下两种可能的对应关系，具体可以为：
1、第一极化信息与第二极化信息一一对应，即一个第一极化信息对应一个第二极化信息；
2、至少两个第二极化信息对应相同的第一极化信息。
在本实施例中，第一极化信息集合有N个第一极化信息，因此接收设备需要对第三极化信息集合遍历N次，每次确定出一个第二极化信息，一种可能的情况是，两次或两次以上对第三极化信息集合进行遍历时确定出的第二极化信息是相同的，因此有至少两个第二极化信息对应相同的第一极化信息。
需要说明的是，在本实施例中，发射设备按照第一极化信息发射电磁波时，接收设备也需要同步按照第二极化信息接收电磁波，例如第一极化信息集合为a1，b1，c1，d1，对应的第二极化信息集合为a2，b2，c2，d2，接收端按照a1发射电磁波，接收端的极化状态需要进行同步切换，按照a2接收电磁波。
在本实施例中的同步切换并不一定是时间上的同步，接收端相对于发射端同步切换是由一定时延的，这个时延具体主要为接收信号的传播时延和接收设备对信号的处理时延。
403、接收设备确定接收信号的质量集合。
404、接收设备确定质量集合中的最优质量。
405、接收设备发送与最优质量对应的第一极化信息至发射设备。
在本实施例中，实施例步骤403至405与图3所示实施例步骤202至204类似，具体此处不再赘述。
406、接收设备按照与最优质量对应的第二极化信息控制接收设备的极化形状和极化方向。
接收设备确定出与最优质量对应的第二极化信息后，接收设备按照该极化信息设置极化状态RX-POL(极化形状和极化方向)，从而与接收电磁波的极化状态PT-POL进行匹配。
在本实施例中，对接收设备极化状态也需要灵活调整的情况进行了说明，接收设备的灵活调整，可以使得无论TX-POL透射后的PT-POL怎么变化，通过发射设备自动调整，RX-POL都能达到最优匹配，从而避免了极化状态不匹配带来的能量损耗，同样的，由于NLOS信道的物理因素带来的缺陷，本申请采用和图3所示实施例类似的方式，确定与接收信号的最优质量对应的第一极化信息控制发射设备，还需要确定出与接收信号的最优质量对应的第二极化信息控制接收设备，就能使得NLOS信道的折射、透射等现象带来的损耗降至最低，在无线通信中，有利用降低信号劣化程度，提升用户体验。
本申请实施例可应用于信道情况不断变化的场景，在NLOS信道情况不断变化时，发射设备通过执行图4所示实施例的步骤，能使接收设备与发射设备自动调整到最优质量对应的极化状态，因此无论信号如何变化，本申请实施例都能使能量损耗降至最低。
在本应用场景中，NLOS信道发生变化可能会导致接收信号劣化，当接收信号劣化程度过高，大于预置的门限值时，触发接收设备执行图4所示实施例的步骤。还有一种可能的情况是采用定时触发方式，接收设备在预置时间达到后触发执行图4所示实施例的步骤。也可以同时采用定时触发和信号劣化触发，具体此处不作限定。
在本实施例中，接收信号劣化程度过高，大于预置的门限值的一种可能情况是，接收信号严重劣化，RSL的值降低到RX的接收灵敏度以下，此时RX端无法接收到信号。预置门限值为预先设置的接收信号RSL可降低值，例如预置门限值为10db，当接收信号RSL的减小值超过10db，发射设备重新进行极化遍历，对应接收设备也重新开始接收第一极化信息集合。
在本实施例中，预置周期到为预先设置的时间周期，可以为5s，也可以为10s，当预置的时间周期达到后，发射设备开始遍历极化配置图中的极化信息生成第一极化信息集合，接收设备也触发接收第一极化信息集合的步骤，因此发射设备每隔预置一定的时间周期就触发执行极化遍历。
上面图3和图4从接收设备的角度对本申请实施例进行了叙述，请参照图5，下面将从发射设备的角度对本申请实施例进行说明。
501、发射设备生成第一极化信息集合。
发射设备对极化配置图中的极化信息进行全部或部分遍历，不断切换发射电磁波的极化状态(即极化形状和极化方向)，发射设备遍历过的极化状态即形成第一极化信息集合。
发射设备按照极化配置表进行极化遍历的具体步长与实施例步骤301类似，具体此处不作限定。
502、发射设备发送第一极化信息集合至接收设备。
遍历极化配置图的同时，发射设备每按照一个第一极化信息发射一次电磁波，就把该第一极化信息发送给接收设备，如此循环，发射设备遍历完成后，接收设备就收到了第一极化信息集合。
接收设备接收第一极化信息集合后需要确定出与第一极化信息集合中的第一极化信息唯一对应的接收信号的质量，该接收信号的质量属于接收信号的质量集合。
在本实施例中，确定接收信号质量的方式与实施例步骤302类似，具体此处不再赘述。
在本实施例中第一极化信息与接收信号质量的对应关系与实施例步骤302类似，具体此处不再赘述。
一种可能的情况是，当接收设备采用全极化天线时，还存在第二极化信息集合的概念，第一极化信息集合可以用于接收设备确定第二极化信息集合，第二极化信息集合确定的方式与实施例402中A、B和C类似，具体此处不再赘述。
在本实施例中，第二极化信息用于控制发射设备的极化状态RX-POL与接收电磁波的极化状态PT-POL相匹配。所述第一极化信息集合中的第一极化信息对应唯一的第二极化信息集合中的第二极化信息，具体的对应关系与实施例步骤402类似，具体此处不再赘述。
在本实施例中，发射设备按照第一极化信息切换发射电磁波的极化状态TX-POL，此时接收设备需要按照与该第一极化信息对应的第二极化信息同步切换接收设备的极化状态RX-POL，同步的方式与实施例步骤402类似，具体此处不再赘述。
503、发射设备接收接收设备发送的第一最优极化信息。
在本实施例中，第一最优极化信息为第一极化信息集合中使接收信号劣化程度最小的极化信息，第一最优极化信息与接收信号的最优质量对应，最优质量的确定方式与实施例步骤303所述的一、二种情况类似，具体此处不再赘述。
504、发射设备根据第一最优极化信息确定发射电磁波的极化形状和极化方向。
在本申请实施例中，发射设备通过发送遍历形成的第一极化信息集合至接收设备，使得接收设备确定出与第一极化信息集合对应的接收信号质量集合，从而确定出哪一个第一极化信息使得接收信号劣化程度最小，此时接收设备只需要接收该第一最优极化信息，并按照该第一最优极化信息发射电磁波，就能使得NLOS信道的折射、透射等现象带来的损耗降至最低，在无线通信中，有利用降低信号劣化程度，提升用户体验。
本申请实施例可应用于信道情况不断变化的场景，在NLOS信道情况不断变化时，发射设备通过执行图5所示实施例的步骤，能使接收设备与发射设备自动调整到最优质量对应的极化状态，因此无论信号如何变化，本申请实施例都能使能量损耗降至最低。
在本应用场景中，NLOS信道发生变化可能会导致接收信号劣化，当接收信号劣化程度过高，大于预置的门限值时，触发发射设备执行图5所示实施例的步骤。还有一种可能的情况是采用定时触发方式，发射设备在预置时间达到后触发执行图5所示实施例的步骤。也可以同时采用定时触发和信号劣化触发，具体此处不作限定。
在本申请实施例中，发射设备与接收设备之间的信息交互是通过控制信道来进行的， 请参照图6，下面进行说明。
601、发射设备生成第一极化信息集合。
602、发射设备发送第一极化信息集合至接收设备。
在本实施例中，实施例步骤601、602与图5所示实施例步骤501、502类似，具体此处不再赘述。
603、接收设备确定接收信号的质量集合。
604、接收设备确定质量集合中的最优质量。
605、接收设备发送与最优质量对应的第一极化信息至发射设备。
在本实施例中，实施例步骤603至605与图3所示实施例步骤302至304类似，具体此处不再赘述。
606、发射设备根据与最优质量对应的第一极化信息确定发射电磁波的极化形状和极化方向。
在本实施例中，实施例步骤605与图5所示实施例步骤504类似，具体此处不再赘述。
需要说明的是，发射设备发送第一极化信息至接收设备可以通过控制信道进行发射，控制信道有两种：随路控制信道和旁路控制信道。
1、随路控制通道的控制信息与数据通道走的同一物理信道，因此发射设备通过随路控制通道的控制信息携带第一极化信息集合后，再发送控制信息至接收设备，就可以实现接收设备与发射设备间信息的传递。
2、旁路控制信道的控制通道与数据通道走不同的物理信道，发射设备通过旁路控制通道发送所述第一极化信息至接收设备，接收设备收到数据流后，不能确定出数据流与极化信息的对应关系，因此需要将数据流与所述第一极化信息进行匹配，从而再根据所述数据流和匹配结果确定第一极化信息，直至完成第一极化信息集合中第一极化信息的确定。
在本实施例中，发射设备对极化配置图进行一次遍历后，接收设备需要对发射设备在每种极化状态下产生的接收信号的质量进行检测，从而确定出使接收信号劣化程度最小的第一极化信息，发射设备按照此极化信息发射电磁波，就可以使NLOS信道的物理损耗降至最低。
本申请实施例可应用于信道情况不断变化的场景，在NLOS信道情况不断变化时，发射设备和接收设备通过执行图6所示实施例的步骤，能使接收设备与发射设备自动调整到最优质量对应的极化状态，因此无论信号如何变化，本申请实施例都能使能量损耗降至最低。
在本应用场景中，NLOS信道发生变化可能会导致接收信号劣化，当接收信号劣化程度过高，大于预置的门限值时，触发发射设备执行遍历发射电磁波的极化形状和极化方向并生成第一极化信息集合步骤。还有一种可能的情况是采用定时触发方式，发射设备在预置时间达到后触发执行遍历发射电磁波的极化形状和极化方向并生成第一极化信息集合的步骤。也可以同时采用定时触发和信号劣化触发，具体此处不作限定。
