Description

极化重配置的方法和通信装置

为了避免卫星波束和卫星系统间的干扰，通过极化复用的方式来可以大大提高卫星频谱的利用率，如图1中为典型的四色波束复用，其中包含频率复用和极化复用的技术，传统卫星网络均采用左旋圆极化(left hand circular polarization，LHCP)或者右旋圆极化(right hand circular polarization，RHCP)，也有少数的卫星通信网络采用垂直线极化或者交叉线极化的方式。
现有技术中，终端设备通过对多个邻区波束进行测量，解调获取邻区网络设备发出的极化指示消息。对全极化终端设备来说增加一定的测量开销，对于重构极化终端来说需要调整终端设备的硬件极化属性才能获取邻区的指示消息，由于切换时延的问题，会导致用户无法及时跟踪小区或者邻区的极化特征变化，造成当前进行中的业务中断，小区的重搜索，重复同步和接入过程。

具体实施方式
下面将结合附图，对本申请中的技术方案进行描述。
本申请的技术方案可以应用于各种通信系统，例如：全球移动通讯(global system of mobile communication，GSM)系统、码分多址(code division multiple access，CDMA)系统、宽带码分多址(wideband code division multiple access，WCDMA)系统、通用分组无线业务(general packet radio service，GPRS)、长期演进(long term evolution，LTE)系统、LTE频分双工(frequency division duplex，FDD)系统、LTE时分双工(time division  duplex，TDD)、通用移动通信系统(universal mobile telecommunication system，UMTS)、全球互联微波接入(worldwide interoperability for microwave access，WiMAX)通信系统、第五代(5th generation，5G)系统或新无线(new radio，NR)、未来的移动通信系统，以及卫星通信系统、高空平台(high altitude platform station,HAPS)通信等非地面网络(non-terrestrial network,NTN)系统。此外，本申请的技术方案还可以应用于卫星通信系统与上述传统的移动通信系统相融合的通信系统中，本申请对此不做具体限定。
参见图2，图2为适用于本申请实施例的通信系统的架构。如图2所示，该通信系统为一个或多个轨道的卫星通信系统(例如：静止轨道(geostationary earth orbit,GEO)、中轨道(medium earth orbit,MEO)或低轨道(low earth orbit,LEO)等)或者由多种非地面网络包含不限于卫星，高空平台，飞艇，无人机通信系统与地面移动通信所构成的天地一体融合网络架构，为地面终端提供广域覆盖通信服务。卫星可以是为非静止轨道(non-geostationary earth orbit,NGEO)卫星或静止轨道(geostationary earth orbit,GEO)卫星。本申请实施例中提及网络设备，可以是卫星，也可以为卫星基站，或者为搭载在卫星上的网络侧设备。
本申请实施例中提及的终端设备，包括各种具有无限通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其它处理设备，具体可以指用户设备(user equipment,UE)、接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。终端设备还可以是卫星电话、蜂窝电话、智能手机、无线数据卡、无线调制解调器、机器类型通信设备、可以是无绳电话、会话启动协议(session initiation protocol，SIP)电话、无线本地环路(wireless local loop，WLL)站、个人数字处理(personal digital assistant，PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备或可穿戴设备，虚拟现实(virtual reality，VR)终端设备、增强现实(augmented reality，AR)终端设备、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程医疗(remote medical)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端、5G网络或者未来通信网络中的终端设备等。
现有地面LTE/NR网络中，基站(gNB)主要采用线极化进行信号传输。具体来说，gNB同时发送水平极化和垂直极化(或±45线极化)信号，终端设备同时接收上述两种极化信号，以获得复用增益。卫星通信网路中，较为常见的采用固定极化复用的方法，即如图1所示，并通过一定的原则，将卫星中相邻的潜在会产生强烈干扰的波束通过不同的极化方式加以分配。
例如，参见图3，图3是当卫星小区内或者小区间突发干扰时，用户极化调整的示意图。如图3所示，原有T0时刻，卫星α下用户A和用户B与卫星波束采用相同极化，例如均为RHCP。T1时刻，有来自同一星座或不同星座的卫星β的波束与原有波束采用相同的RHCP极化，原有卫星α由于干扰问题无法工作，需要将小区内的用户A和用户B全部切换为LHCP，或者仅仅将被干扰部分的用户B的极化切换为LHCP，原用户A的极化特性保持不变。
或者，参见图4，图4是当网络对基站进行资源调度和优化时，用户极化调整的示意 图。如图4所示，当原有卫星α覆盖下的区域容量需求发生变化时，需要采用2个更高增益的窄波束进行通信覆盖，则两个波束下的不同用户间采用相同极化会产生强烈干扰，用户A和用户B需要采用不同的极化减小干扰，例如：可以将用户A的极化特性维持不变，用户B的极化特性切换为LHCP。
随着大规模卫星星座技术以及天地一体化网络技术的发展，未来的网络将是一种由多个相同或不同轨道的卫星网络结合地面网络的异构组网形式，而不是单一卫星网络存在的，空间的频谱和轨道资源的竞争越来越激烈，系统内或系统间的干扰协调和优化是融合异构网络的重大问题，同样随着容量需求的变化，卫星通信网络的资源配置也需要根据用户的需求进行相应的改变和资源调度重构，以获取资源收益的最大化。
下面介绍本申请的技术方案。
参见图5，图5是本申请提出的一种极化重配置的方法的示意图。
501、终端设备接收网络设备发送的第一消息。
对应的，网络设备向终端设备发送第一消息，第一消息包括第一指示信息，第一指示信息包括第二极化的信息，以指示终端设备从当前工作的极化方式(即第一极化方式)切换为第二极化方式。
可选的，第一指示信息指示的切换方法可以为绝对指示法或者相对指示法。
①相对指示法：网络设备可以根据1bit(1或0)指示终端设备需要切换的第二极化的信息。
例如：0：表示第二极化为与第一极化正交的极化方式。例如：当第一极化为左旋圆极化时，第一指示信息表示终端设备需要切换的第二极化为右旋圆极化；或者，当第一极化为水平极化时，第一指示信息表示终端设备需要切换的第二极化为垂直极化等。
1：表示第二极化为与第一极化类型不同的极化方式(即终端设备在在圆极化和线极化或交叉极化之间进行切换)。例如：当第一极化为左旋圆极化时，第一指示信息表示终端设备需要切换的第二极化为线极化；或者，当第一极化为右旋圆极化时，第一指示信息表示终端设备需要切换的第二极化为交叉极化；或者，当第一极化为左旋圆极化时，第一指示信息表示终端设备需要切换的第二极化为交叉极化；或者，当第一极化为右旋圆极化时，第一指示信息表示终端设备需要切换的第二极化为线极化等。
可选的，当第一指示信息的切换方法为相对指示法时，第一信息以事件触发的方式发送给终端设备。例如：当网络设备需要覆盖重构时，或者网络设备受到干扰时，或者网络设备需要波束切换时触发第一指示信息的发送。
②绝对指示法：网络设备可以根据1bit或多bit指示终端设备需要切换的第二极化方式的索引。
例如：0：切换为左旋圆极化；1：切换为右旋圆极化；2：切换为水平极化；3：切换为垂直极化；4：切换为45°交叉极化。
需要说明的是，在一些情况下，第二极化也可以为与第一极化相同的极化方式，本申请对此不做具体限定。
可选的，当第一指示信息的切换方法为绝对指示法时，第一指示信息可以按预设周期发送给终端设备，或者，以事件触发的方式发送给终端设备。
可选的，第一消息可以为以下消息中的任意一种：系统信息块(system information  blocks，SIB)(包括但不局限于SIB3或SIB4等)、无线资源控制消息(radio resource control，RRC)、下行控制信息(downlink control information，DCI)以及媒体接入控制层控制元素(medium access control elements，MAC CE)消息。
需要说明的是，当第一消息为DCI消息时，原DCI字段为N比特的0、1序列，需要在原DCI消息中增加一个1bit承载第一指示信息。
502、终端设备根据第一指示信息从第一极化切换为第二极化。
可选的，第一消息还包括第二指示信息，第二指示信息用于指示终端设备生效第一指示信息的时间偏移量L，L大于或等于0。例如：终端设备在时隙n接收到第一消息，则终端设备设备根据第二指示信息在时隙(n+L)生效第一指示信息，即在时隙(n+L)从第一极化切换到第二极化。
需要说明的是，当第一消息为DCI消息时，原DCI字段为N比特的0、1序列，可以在原DCI消息中增加另一个1bit承载第二指示信息。参见图6，图6是本申请提供的一种网络设备通过DCI消息传输第一指示信息和第二指示信息的示意图。
可选的，当第一消息为DCI消息时，终端设备根据第二指示信息生效所述第一指示信息的时间单元的表达式为：

其中，

表示向下取整，n为接收到DCI消息的时隙，μ PDSCH和μ PDCCH分别为物理下行共享信道(physical downlink shared channel，PDSCH)和物理下行控制信道(physical downlink control channel，PDCCH)子载波间隔，L为生效第一指示信息的时间偏移量。
可选的，在第一消息不包括第二指示信息的情况下，终端设备的极化方式的切换时间门限要求可以通过协议要求进行约定，或者，终端设备在时隙n接收到第一指示信息后，在最近的时隙生效第一指示信息。
可选的，503、在终端设备接收网络设备发送的第一消息之前(即501之前)，该方法还包括：终端设备向网络设备发送第一能力消息，第一能力消息包括终端设备支持的极化特性的参数。例如：第一能力消息可以添加在终端设备的能力(category)表中。这样，网络设备可以根据终端设备上报的第一能力消息对终端设备进行相应的极化变更指示，更加有效的提升小区间的干扰协调能力。
可选的，终端设备的支持的极化特性的参数可以添加在UE-NR-Capability集合中的rf-parameters子集序列表中，用于说明终端设备所支持的极化特性种类：如表1所示，分别代表左旋圆极化(LHCP)，右旋圆极化(RHCP)，水平极化(horizontal)，垂直极化(vertical)，交叉极化(cross)等能力支持情况。
表1
极化方式 终端能力(是否支持) 是否可选能力
RHCP 支持/不支持 可选

cross 支持/不支持 可选
可选的，终端设备可以是周期性的向网络设备上报第一能力消息。
可选的，网络设备也可以向终端设备发送能力协商消息，以指示终端设备上报终端设备支持的极化方式或第一能力消息。
作为一种示例，本申请还提出一种在卫星小区间传输极化切换指示信息(即第一指示信息)的方法。例如：卫星小区间可以通过XnAP消息从本小区向目标小区传输极化切换指示信息，以提升小区间干扰协调能力。发送方源卫星发出极化切换指示信息，接收方目标卫星根据该指示信息对目标波束进行相应极化调整，关于极化切换指示信息和时间偏移量指示信息参见上文的描述，不再赘述。例如极化切换指示消息格式可以如表2所示：
