Description

极化指示、极化确定方法和装置、通信装置和存储介质 技术领域
本公开涉及通信技术领域，具体而言，涉及极化指示方法、极化确定方法、极化指示装置、极化确定装置、通信装置和计算机可读存储介质。
背景技术
在地面网络中，终端与基站之间通信的极化方式一般是固定的线极化方式。但是在非地面网络(Non-Terrestrial Networks，NTN)中，终端需要通过卫星进行通信。
由于卫星是在高空工作，卫星与终端通信时传输的信号需要经过电离层和雨雾层，因此也就会受到电离层与雨雾层的影响。线极化方式的信号在经过电离层时，会受到电磁干扰而使极化方向发生偏转，或者受到雨雾层影响而发生误码现象。由于这些因素的影响，卫星一般采用圆极化方式通信。
由于终端一般采用线极化方式通信，而卫星一般采用圆极化方式通信，这就导致终端与卫星通信的极化方式不一致，从而影响终端与卫星的通信质量，甚至导致卫星与终端不能通信。

具体实施方式
下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
在本公开实施例使用的术语是仅仅出于描述特定实施例的目的，而非旨在限制本公开实施例。在本公开实施例和所附权利要求书中所使用的单数形式的“一种”和“该”也旨在包括多数形式，除非上下文清楚地表示其他含义。还应当理解，本文中使用的术语“和/或”是指并包含一个或多个相关联的列出项目的任何或所有可能组合。
应当理解，尽管在本公开实施例可能采用术语第一、第二、第三等来描述各种信息，但这些信息不应限于这些术语。这些术语仅用来将同一类型的信息彼此区分开。例如，在不脱离本公开实施例范围的情况下，第一信息也可以被称为第二信息，类似地，第二信息也可以被称为第一信息。取决于语境，如在此所使用的词语“如果”可以被解释成为“在……时”或“当……时”或“响应于确定”。
出于简洁和便于理解的目的，本文在表征大小关系时，所使用的术语为“大于”或“小于”、“高于”或“低于”。但对于本领域技术人员来说，可以理解：术语“大于”也涵盖了“大于等于”的含义，“小于”也涵盖了“小于等于”的含义；术语“高于”涵盖了“高于等于”的含义，“低于”也涵盖了“低于等于”的含义。
图1是根据本公开的实施例示出的一种极化指示方法的示意流程图。本实施例所示的极化指示方法可以适用于基站，所述基站可以在非地面网络中与终端通信，例如可以通过空中的卫星与终端通信，其中，通过卫星通信的方式包括但不限于透传和非透传(可以称作星上再生)等方式。在相关技术中，透传模式是指基站与卫星是分离的两个设备；非透传模式是指卫星可以作为基站工作，即卫星与基站是同一个电子设备或是同一个电子设备的不同电路板。本公开的所有实施例中，并不限定所述基站和卫星是否为同一个设备。同时，本领域内技术人员可以理解，当卫星和基站是同一个设备时，在实施例中提到的卫星和基站可以为同一个主体(即使采用了不同的名字)。
在一个实施例中，所述终端包括但不限于手机、平板电脑、可穿戴设备、传感器、物联网设备等通信装置。所述基站包括但不限于4G基站、5G基站、6G基站等 通信系统中的基站。所述基站可以为非地面网络中的基站，所述终端可以为非地面网络中的终端。
如图1所示，所述极化指示方法可以包括以下步骤：
在步骤S101中，向终端发送第一指示信息，其中，所述第一指示信息用于指示所述终端与非地面网络中的卫星通信使用的目标极化方式。
在一个实施例中，终端在确定目标极化方式之前，可以通过某些方式接收到卫星发送的下行信号，进而接收到第一指示信息。例如终端可以对卫星发送的下行信号进行盲检测，或者卫星采用圆极化方式发送下行信号，那么终端即使采用陆地通信系统中普遍使用的线极化方式也能接收到信号，只是接收效果稍微差一些可能需要通过多次接收获取到可靠的第一指示信息。
在终端确定目标极化方式之后，就可以通过目标极化方式与卫星通信。例如根据第一指示信息确定目标极化方式为下行通信的极化方式，那么可以通过目标极化方式接收卫星通过目标极化方式发送的下行信号；例如根据第一指示信息确定目标极化方式为上行通信的极化方式，那么可以通过目标极化方式向卫星发送上行信号。
在一个实施例中，基站指示给终端的目标极化方式，也可以是卫星与终端通信采用的极化方式。例如基站确定卫星通信使用极化方式为目标极化方式，目标极化方式可以是协议约定的，或者是卫星自主确定后告知基站的，或者是基站自主确定的，或者是卫星与基站协商确定的。
以基站自主确定为例，基站可以根据地面与卫星之间的电离层和/或雨雾层对信号传输的影响情况，确定目标极化方式，使得卫星基于目标极化方式通信，可以最大程度上克服电离层和/或雨雾层对信号传输的影响。或者基站也可以基于其服务的小区内终端的天线极化方式，确定目标极化方式。
在一个实施例中，基站在确定目标极化方式之后，可以生成用于指示目标极化方式的第一指示信息，并将第一指示信息发送至终端，从而使得终端可以根据第一指示信息确定与非地面网络中的卫星通信使用的目标极化方式，进而采用目标极化方式与卫星通信，避免终端与卫星通信时，终端采用的极化方式与卫星采用的极化方式不同，确保终端与卫星之间能够进行良好的通信。
在一个实施例中，在第一指示信息中还可以携带有目标极化方式的时效信息，所述时效信息可以是实际时间，也可以是逻辑时间，例如起始和结束包括系统帧号、 时隙、时域符号等。终端可以在该时效信息对应的有效时长内使用目标极化方式与卫星通信；在时效信息对应的有效时长后，可以再次接收基站发送的第一指示信息，或者请求基站再次发送第一指示信息，并根据再次接收到的第一指示信息所指示的目标极化方式与卫星通信。
在一个实施例中，在第一指示信息中还可以携带有目标极化方式的业务信息，所述业务信息可以包括一种或多个业务类型，或者不包含具体的业务类型，默认指示终端当前进行的业务。终端可以在进行业务信息对应业务类型的信息传输时，使用目标极化方式与卫星通信；在进行其他业务类型的信息传输时，可以再次接收基站发送的第一指示信息，或者请求基站再次发送第一指示信息(可以在请求中携带其他业务类型的信息，以便基站指示的目标极化方式与其他业务类型对应)，并根据再次接收到的第一指示信息所指示的目标极化方式与卫星通信。
在一个实施例中，所述目标极化方式包括以下至少之一：线性极化、圆极化、左旋极化、右旋极化。
在一个实施例中，确定卫星通过第一指示信息指示的目标极化方式，可以包括针对上行传输的上行目标极化方式和针对下行传输的下行目标极化方式。其中，上行目标极化方式和下行目标极化方式可以相同也可以不同。终端可以采用上行目标极化方式进行上行传输，采用下行目标极化方式接收下行信号，例如上行目标极化方式为左旋极化，下行目标极化方式为右旋极化，终端可以采用左旋极化方式向卫星发送信息，采用右旋极化方式接收卫星发送的信息。
可以理解的，可以由基站确定卫星通过第一指示信息指示的目标极化方式，也可以由卫星确定卫星通过第一指示信息指示的目标极化方式。当卫星作为基站工作时，两者为同一个设备，该设备确定卫星通过第一指示信息指示的目标极化方式。卫星和基站可以为同一个设备的表述，同样适用于随后的所有实施例中，因此在后不再赘述。
在一个实施例中，第一指示信息占用比特的数量，基于目标极化方式的可选方式的数量而定。
例如目标极化方式的可选方式只包括线性极化和圆极化两种，那么第一指示信息可以占用1个比特，例如该比特为1时表示目标极化方式为线性极化，该比特位0时表示目标极化方式为圆极化。
例如目标极化方式的可选方式只包括线性极化、圆极化、左旋极化和右旋极化 四种，那么第一指示信息可以占用2个比特，例如11表示目标极化方式为线性极化，00表示目标极化方式为圆极化，01表示目标极化方式为右旋极化，10表示目标方式为左旋极化。
在一个实施例中，所述向终端发送第一指示信息包括：通过显式方式和/或隐式方式向所述终端发送所述第一指示信息。
基站或卫星(以下称为网络设备，即网络设备可以为基站，也可以为卫星；当基站和卫星为同一设备时，网络设备即为该设备)可以通过显示方式向终端发送第一指示信息，也可以通过隐式方式向终端发送指示信息，网络设备可以根据需要选择发送第一指示信息的方式，可以择一执行，也可以两种方式都执行。
在一个实施例中，所述通过显式方式向所述终端发送所述第一指示信息包括：向所述终端发送下行控制信息，其中，所述第一指示信息携带在所述下行控制信息中。
网络设备可以向终端发送下行控制信息(Downlink Control Information，DCI)，并可以将第一指示信息携带在下行控制信息中，据此，无需单独发送第一指示信息，有利于节约通信资源。
在一个实施例中，所述第一指示信息位于所述下行控制信息中新增的专用于指示目标极化方式的信息域，或者位于所述下行控制信息中已有的用于指示其他信息的信息域，其中，所述其他信息至少在所述网络设备与所述终端的部分通信过程中不发送。
网络设备可以在下行控制信息中新增信息域，该信息域专用于指示目标极化方式，进而可以将第一指示信息设置在该信息域。
网络设备也可以将第一指示信息设置在下行控制信息中已有的信息域，该信息域用于指示其他信息，但是其他信息至少在网络设备与终端的部分通信过程中不发送，据此，可以尽量减小将第一指示信息设置在该信息域对其他信息的影响。
例如其他信息可以是混合自动重传请求(Hybrid Automatic Repeat reQuest，HARQ)信息，传输块(Transport Block，TB)调度信息。以混合自动重传请求信息为例，网络设备与终端在非地面网络中通信时，由于需要通过卫星通信，通信时延较大，因此可以执行混合自动重传请求的相关机制，也就不发送混合自动重传请求信息，在这种情况下，可以将第一指示信息设置在下行控制信息中用于指示混合自动重传请求信息的信息域，从而充分利用下行控制信息中的信息域。
需要说明的是，网络设备向终端发送的第一指示信息，并不限于携带在下行控制信息中，也可以携带在其他下行信息中，例如也可以携带在高层信令、介质访问控制层控制元素(Media Access Control Control Element，MAC CE)中。
在一个实施例中，所述通过隐式方式向所述终端发送所述第一指示信息包括：确定所述目标极化方式对应的加扰序列和/或无线网络临时标识；向所述终端发送信令，其中，所述信令通过所述加扰序列和/或所述无线网络临时标识加扰。
网络设备可以选择目标极化方式对应的加扰序列加扰向终端发送的信令，也可以通过目标极化方式对应的无线网络临时标识(Radio Network Tempory Identity，RNTI)加扰向终端发送的信令，所述信令可以是调度信令，例如可以加扰在调度信息的CRC(Cyclic Redundancy Check，循环冗余校验)上。
例如网络设备通过目标极化方式对应的加扰序列加扰向终端发送的信令，终端接收到信令后，可以通过至少一个解扰序列对信令进行解扰，每个解扰序列分别对应一种极化方式，当成功解扰时，可以确定成功解扰信令所采用的解扰序列对应的极化方式为目标极化方式。
例如网络设备通过目标极化方式对应的无线网络临时标识加扰向终端发送的信令，终端接收到信令后，可以通过至少一个无线网络临时标识对信令进行解扰，每个无线网络临时标识分别对应一种极化方式，当成功解扰时，可以确定成功解扰信令所采用的无线网络临时标识对应的极化方式为目标极化方式。
据此，无需网络设备直接向终端发送第一指示信息，即可使得终端确定目标极化方式，有利于节约通信资源。
在一个实施例中，网络设备通过隐式方式向终端发送第一指示信息，也可以是指网络设备发送一次第一指示信息后，终端后续通信也采用这次接收到的第一指示信息指示的目标极化方式与卫星通信。例如终端接收到一次第一指示信息后，需要在有效时长后再次接收第一指示信息，以重新确定目标极化方式，但是终端在有效时长后如果没有再次接收第一指示信息，在需要与卫星通信时，仍可以采用最近一次接收到的第一指示信息所指示的目标极化方式与卫星通信。
在一个实施例中，网络设备通过隐式方式向终端发送第一指示信息，也可以是指网络设备通过第一指示信息指示的目标极化方式对应上行传输和下行传输中的一者，终端在进行上行传输和下行传输中的另一者时，采用这次接收到的第一指示信息 指示的目标极化方式或目标极化方式相反的极化方式与卫星通信。例如第一指示信息后指示终端进行上行传输时采用目标极化方式与卫星通信，那么终端在进行下行传输时，也可以采用目标极化方式与卫星通信。
本公开的实施例提出了一种极化确定方法的示意流程图，所述方法包括：从终端支持的极化方式中，确定目标计划方式。
在一些可能的实施方式中，该方法可以单独被实施，也可以配合本公开的任何一个其他实施例一起被实施，例如可以配合步骤101一起被实施。
在一些可能的实现方式中，该方法可以如图2所示的，包括
在步骤S201中，接收所述终端发送的能力信息，根据所述能力信息确定所述终端支持的极化方式；
在步骤S202中，在所述终端支持的极化方式中确定所述目标极化方式。
在一个实施例中，终端可以向网络设备上报终端的能力信息，通过能力信息可以告知网络设备终端所支持的极化方式，进而网络设备可以在终端支持的极化方式中确定目标极化方式。据此，可以确保网络设备确定的目标极化方式是终端支持的极化方式，确保终端能够使用目标极化方式与卫星通信。
图3是根据本公开的实施例示出的一种极化指示方法的示意流程图。如图3所示，所述方法包括：
在步骤S301中，向非地面网络中的卫星发送第二指示信息，其中，所述第二指示信息用于所述卫星使用所述目标极化方式与所述终端通信。
在一些可能的实施方式中，该方法可以单独被实施，也可以配合本公开的任何一个其他实施例一起被实施，例如可以配合步骤101和/或步骤201&202一起被实施。
在一个实施例中，卫星还可以向卫星发送第二指示信息，通过第二指示信息指示卫星使用目标极化方式与终端通信，据此，可以确保终端和卫星都使用目标极化方式通信。
需要说明的是，在目标极化方式是基站自主确定的情况下，才执行步骤S301，在目标极化方式是卫星自主确定并告知基站时，或者卫星与基站协商确定时，由于卫星已经知道了目标极化方式，因此可以不必执行步骤S301，以免浪费通信资源。当然，如果卫星和基站是同一设备时，也可以不必执行步骤S301。
图4是根据本公开的实施例示出的一种极化确定方法的示意流程图。本实施例所示的极化指示方法可以适用于终端，所述终端可以在非地面网络中与基站通信，例如可以通过空中的卫星与基站通信，其中，通过卫星通信的方式包括但不限于透传和非透传(可以称作星上再生)等方式。
在一个实施例中，所述终端包括但不限于手机、平板电脑、可穿戴设备、传感器、物联网设备等通信装置。所述基站包括但不限于4G基站、5G基站、6G基站等通信系统中的基站。所述基站可以为非地面网络中的基站，所述终端可以为非地面网络中的终端。
如图4所示，所述极化确定方法可以包括以下步骤：
在步骤S401中，根据网络设备发送的第一指示信息确定与所述网络设备通信使用的目标极化方式。
在一个实施例中，终端在确定目标极化方式之前，可以通过某些方式接收到卫星发送的下行信号，进而接收到第一指示信息。例如终端可以对卫星发送的下行信号进行盲检测，或者卫星采用圆极化方式发送下行信号，那么终端即使采用一般通信过程中的线极化方式也能接收到一部分信号，只是接收效果稍微差一些，即使一次接受不能获取到完整的第一指示信息，也可以通过多次接收获取到完整的第一指示信息。
在终端确定目标极化方式之后，就可以通过目标极化方式与卫星通信。例如根据第一指示信息确定目标极化方式为下行通信的极化方式，那么可以通过目标极化方式接收卫星通过目标极化方式发送的下行信号；例如根据第一指示信息确定目标极化方式为上行通信的极化方式，那么可以通过目标极化方式向卫星发送上行信号。
在一个实施例中，网络设备指示给终端的目标极化方式，也可以是卫星与终端通信采用的极化方式。例如网络设备确定卫星通信使用极化方式为目标极化方式，目标极化方式可以是协议约定的，或者是卫星自主确定后告知基站的，或者是基站自主确定的，或者是卫星与基站协商确定的。当然，如果卫星和基站是同一设备时(也称为网络设备)，目标极化方式可以是协议约定的，也就可以由该网络设备确定。
以网络设备自主确定为例，网络设备可以根据地面与卫星之间的电离层和/或雨雾层对信号传输的影响情况，确定目标极化方式，使得卫星基于目标极化方式通信，可以最大程度上克服电离层和/或雨雾层对信号传输的影响。
在一个实施例中，网络设备在确定目标极化方式之后，可以生成用于指示目标 极化方式的第一指示信息，并将第一指示信息发送至终端，从而使得终端可以根据第一指示信息确定与非地面网络中的卫星通信使用的目标极化方式，进而采用目标极化方式与卫星通信，避免终端与卫星通信时，终端采用的极化方式与卫星采用的极化方式不同，确保终端与卫星之间能够进行良好的通信。
在一个实施例中，在第一指示信息中还可以携带有目标极化方式的时效信息，所述时效信息可以是实际时间，也可以是逻辑时间，例如起始和结束包括系统帧号、时隙、时域符号等。终端可以在该时效信息对应的有效时长内使用目标极化方式与卫星通信；在时效信息对应的有效时长后，可以再次接收网络设备发送的第一指示信息，或者请求网络设备再次发送第一指示信息，并根据再次接收到的第一指示信息所指示的目标极化方式与卫星通信。
在一个实施例中，在第一指示信息中还可以携带有目标极化方式的业务信息，所述业务信息可以包括一种或多个业务类型，或者不包含具体的业务类型，默认指示终端当前进行的业务。终端可以在进行业务信息对应业务类型的信息传输时，使用目标极化方式与卫星通信；在进行其他业务类型的信息传输时，可以再次接收网络设备发送的第一指示信息，或者请求网络设备再次发送第一指示信息(可以在请求中携带其他业务类型的信息，以便网络设备指示的目标极化方式与其他业务类型对应)，并根据再次接收到的第一指示信息所指示的目标极化方式与卫星通信。
在一个实施例中，所述目标极化方式包括以下至少之一：线性极化、圆极化、左旋极化、右旋极化。
在一个实施例中，网络设备确定卫星通过第一指示信息指示的目标极化方式，可以包括针对上行传输的上行目标极化方式和针对下行传输的下行目标极化方式。其中，上行目标极化方式和下行目标极化方式可以相同也可以不同。终端可以采用上行目标极化方式进行上行传输，采用下行目标极化方式接收下行信号，例如上行目标极化方式为左旋极化，下行目标极化方式为右旋极化，终端可以采用左旋极化方式向卫星发送信息，采用右旋极化方式接收卫星发送的信息。
在一个实施例中，所述根据网络设备发送的第一指示信息确定与所述网络设备通信使用的目标极化方式包括：接收所述网络设备发送的下行控制信息；从所述下行控制信息中获取所述第一指示信息。
网络设备可以向终端发送下行控制信息，并可以将第一指示信息携带在下行控 制信息中，据此，无需单独发送第一指示信息，有利于节约通信资源。
在一个实施例中，所述从所述下行控制信息中获取所述第一指示信息包括：从所述下行控制信息中新增的专用于指示目标极化方式的信息域获取所述第一指示信息；或者从位于所述下行控制信息中已有的用于指示其他信息的信息域获取所述第一指示信息，其中，所述其他信息至少在所述网络设备与所述终端的部分通信过程中不发送。
网络设备可以在下行控制信息中新增信息域，该信息域专用于指示目标极化方式，进而可以将第一指示信息设置在该信息域。
网络设备也可以将第一指示信息设置在下行控制信息中已有的信息域，该信息域用于指示其他信息，但是其他信息至少在网络设备与终端的部分通信过程中不发送，据此，可以尽量减小将第一指示信息设置在该信息域对其他信息的影响。
例如其他信息可以是混合自动重传请求信息，传输块调度信息。以混合自动重传请求信息为例，网络设备与终端在非地面网络中通信时，由于需要通过卫星通信，通信时延较大，因此可以执行混合自动重传请求的相关机制，也就不发送混合自动重传请求信息，在这种情况下，可以将第一指示信息设置在下行控制信息中用于指示混合自动重传请求信息的信息域，从而充分利用下行控制信息中的信息域。
需要说明的是，网络设备向终端发送的第一指示信息，并不限于携带在下行控制信息中，也可以携带在其他下行信息中，例如也可以携带在高层信令、介质访问控制层控制元素中。
在一个实施例中，所述根据网络设备发送的第一指示信息确定与所述网络设备通信使用的目标极化方式包括：通过解扰序列和/或无线网络临时标识解扰网络设备发送的信令；确定对所述信令解扰成功的解扰序列和/或无线网络临时标识对应的极化方式为所述目标极化方式。
网络设备可以选择目标极化方式对应的加扰序列加扰向终端发送的信令，也可以通过目标极化方式对应的无线网络临时标识加扰向终端发送的信令，所述信令可以是调度信令，例如可以加扰在调度信息的CRC上。
例如网络设备通过目标极化方式对应的加扰序列加扰向终端发送的信令，终端接收到信令后，可以通过至少一个解扰序列对信令进行解扰，每个解扰序列分别对应一种极化方式，当成功解扰时，可以确定成功解扰信令所采用的解扰序列对应的极化 方式为目标极化方式。
例如网络设备通过目标极化方式对应的无线网络临时标识加扰向终端发送的信令，终端接收到信令后，可以通过至少一个无线网络临时标识对信令进行解扰，每个无线网络临时标识分别对应一种极化方式，当成功解扰时，可以确定成功解扰信令所采用的无线网络临时标识对应的极化方式为目标极化方式。
据此，无需网络设备直接向终端发送第一指示信息，即可使得终端确定目标极化方式，有利于节约通信资源。
在一个实施例中，所述方法还包括：响应于在接收到所述第一指示信息后的预设时长内，未接收到所述网络设备发送的用于指示极化方式的其他指示信息，继续通过所述目标极化方式与所述网络设备通信。
终端接收到一次第一指示信息后，需要在预设时长内再次接收第一指示信息，以重新确定目标极化方式，但是终端在有效时长后如果没有再次接收第一指示信息，在需要与卫星通信时，仍可以采用最近一次接收到的第一指示信息所指示的目标极化方式与卫星通信。
在一个实施例中，所述根据网络设备发送的第一指示信息确定与所述网络设备通信使用的目标极化方式包括：
根据所述网络设备发送的第一指示信息确定向所述卫星上行传输的上行极化方式；根据上行传输和下行传输对应极化方式的第一关联关系，确定接收所述卫星下行传输的下行极化方式；或者
根据所述网络设备发送的第一指示信息确定接收所述卫星下行传输的下行极化方式；根据下行传输和下行传输对应极化方式的第二关联关系，确定向所述卫星上行传输的上行极化方式。
网络设备可以通过第一指示信息指示的目标极化方式对应上行传输和下行传输中的一者，终端在进行上行传输和下行传输中的另一者时，可以根据两者对应极化方式的关联关系，确定另一者所需采用的极化方式。
例如第一关联关系为相同，那么终端可以采用上行极化方式作为下行极化方式；例如第一关联关系为相反，那么终端可以采用上行极化方式相反的方式作为下行极化方式。其中，相反的方式是指，线性极化与圆极化相反，左旋极化与右旋极化相反，例如在第一关联关系为相反的情况下，上行极化方式为线极化，终端可以采用圆 极化(可以是左旋极化也可以是右旋极化)作为下行极化方式。
相应地，例如第二关联关系为相同，那么终端可以采用下行极化方式作为上行极化方式；例如第二关联关系为相反，那么终端可以采用下行极化方式相反的方式作为上行极化方式。
