卫星包括低轨道(Low Earth Orbiting,LEO)卫星，中轨道(Medium Earth Orbiting,MEO)卫星，对地静止轨道(Geostationary Earth Orbiting,GEO)卫星以及高椭圆轨道(Highly Elliptical Orbiting,HEO)卫星。终端11也可以称作终端设备或者UE，终端11可以是智能手表、手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)或称为笔记本电脑、个人数字助理(Personal Digital Assistant，PDA)、掌上电脑、上网本、超级移动个人计算机(ultra-mobile personal computer，UMPC)、移动上网装置(Mobile Internet Device，MID)、可穿戴式设备(Wearable Device)或车载设备(VUE)、行人终端(PUE)等终端侧设备，可穿戴式设备包括：手环、耳机、眼镜等。需要说明的是，在本申请实施例并不限定终端11的具体类型。网络侧设备12可以是基站或核心网，其中，基站可被称为节点B、演进节点B、接入点、 基收发机站(Base Transceiver Station，BTS)、无线电基站、无线电收发机、基本服务集(Basic Service Set，BSS)、扩展服务集(Extended Service Set，ESS)、B节点、演进型B节点(evolution Node-B，eNB)、家用B节点、家用演进型B节点、无线局域网(Wireless Local Area Networks，WLAN)接入点、WiFi节点、发送接收点(TransmittingReceivingPoint，TRP)或所述领域中其他某个合适的术语，只要达到相同的技术效果，所述基站不限于特定技术词汇，需要说明的是，在本申请实施例中仅以NR系统中的基站为例，但是并不限定基站的具体类型。
下面结合附图，通过一些实施例及其应用场景对本申请实施例提供的小区重选的方法进行详细地说明。
如图2a所示，本发明的一个实施例提供一种小区重选的方法200，该方法可以由终端设备执行，换言之，该方法可以由安装在终端设备的软件或硬件来执行，该方法包括如下步骤：
S202：终端获取至少一个与目标波束关联的目标配置信息。
在一种实现方式中，在所述目标配置信息为一个的情况下，所述目标波束为终端所在波束。其中，终端驻留在该波束，或在该波束的覆盖范围内，或通过该波束接入网络，或通过该波束与网络进行数据通信，均可以认为该波束是终端所在波束。此时，终端获取的目标配置信息可以为一个。例如，网络设备将所述目标配置信息发送给终端，终端接收该目标配置信息。
通常，在NTN网络中可以执行本步骤。NTN小区具有大覆盖面积，在此情况下，对于驻留在同一个小区的UE可能面临着不同的邻频率。但是通过系统信息广播的小区配置参数应用于小区中所有的UE，可能会导致UE进行不必要的测量。具体例如图2b所示，小区1(Cell 1)的邻小区包含Cell 2和Cell 3，对于驻留在Cell 1的UE1在Cell 2的覆盖范围，驻留在Cell 1的UE2在Cell 3的覆盖范围，Cell 2和Cell 3可能属于不同频率的小区，可能具有不同的频率优先级。若是UE1和UE2应用相同的配置参数，假设频点2 的优先级高于频点1高于频点3，根据小区重选规则，对于高优先级频点，始终执行邻小区测量，因此UE2会不必要的测量频率2的Cell 2。
如图2c所示，在NTN波束覆盖区，可以支持以下两种波束(Beam)和Cell之间的映射关系：
(1)一个Cell对应一个Beam，如Beam 0属于Cell 0，Beam 1属于Cell 1；
(2)一个Cell对应多个Beam，如Beam 0/1/2/3属于同一个Cell，Beam 5/6属于另一个Cell；或Beam 0/1/2/3/4/5/6均属于一个Cell等。
S204：基于所述目标配置信息执行小区重选。
在一种实现方式中，在所述目标配置信息为一个的情况下，所述目标波束为终端所在波束，在本步骤中基于所在波束关联的目标配置信息，执行小区重选。
NTN支持两种波束与小区的关系，并且支持两种beam布局结构，如图2d所示，在一种布局结构中，SSB在smaller beam上传输，终端接收到的广播消息即为终端所在波束的广播消息。如图2e所示，在另一种布局结构中，SSB在umbrella beam上传输，终端接收到的广播消息包含所有波束的广播消息，其中所有波束的广播消息相同或不同。
在一个cell对应多个beam的情况下，例如Beam 0/1/2/3/4/5/6属于cell1，UE1和UE2都驻留在cell1，UE1所在波束为beam0，UE2所在波束为beam6。
在目标配置信息以smallbeam发送的情况下，UE1和UE2可以获取所在波束的目标配置信息，例如UE1获取beam0的配置信息，UE2获取beam6的配置信息，UE1和UE2分别基于所处波束的目标配置信息执行小区重选，从而避免不必要的测量。
在目标配置信息以umbrella beam发送的情况下，UE1和UE2可以获取多个目标波束与目标配置信息，UE1和UE2可以基于所在波束选择一个目标配置信息，并基于该目标配置信息执行小区重选，从而避免不必要的测量。
本发明实施例提供的一种小区重选的方法，通过终端获取至少一个与目标波束关联的目标配置信息；基于所述目标配置信息执行小区重选，能够在NTN中，在不同的波束布局结构下执行小区重选。
本发明实施例提供的一种小区重选的方法，通过所述目标波束为终端所在波束，能够避免终端设备进行不必要的测量，耗费功率。
在一种实现方式中，目标波束与目标配置信息的关联关系，可以包括以下关系中的一项：
一个所述目标波束与一个所述目标配置信息之间的关联关系；
多个所述目标波束与一个所述目标配置信息之间的关联关系。
在一种实现方式中，所述目标配置包括以下至少一项：

在一种实现方式中，所述同频邻小区小区重选相关的信息，包括以下至少一项：

同频邻小区被禁止或保留的信息；
同频邻小区相关的重选参数；

在一种实现方式中，所述异频邻小区小区重选相关信息，包括以下至少一者：

异频邻小区标识；

其中，n为该目标波束在某种可选的排序中的顺序编号。所述第一列表包含至少一个第一配置信息，其中第一列表中的元素可以相同或不同。例如，小区包含4个beam,网络广播第一列表，所述第一列表包含4个第一配置信息，即list1＝{info1,info2,info3,info4}，列表中第n个元素即为第n个的波束的配置信息，例如列表中第2个元素为波束2的配置信息，其中第一列表中的元素可以相同或不同。

再例如，第二列表为：list2＝{list5_1，list5_2},list5_1＝{1},list5_2＝{2 3 4},第三列表list3＝{info1,info2}，List2中第m个元素对应的第二目标波束，其关联的第二配置信息为第三列表中的第m个元素,具体例如m＝2,list2中的第2个元素为list5_2＝{2 3 4}，即波束2，3，4的配置信息为info2。
3、第三目标波束与第三目标配置信息相关联，其中，所述第三目标波束为第六列表中的第一元素对应的目标波束，所述第三目标配置信息为所述第六列表中的第二元素。
所述第六列表包含至少一个目标波束的索引值和至少一个目标配置信息，其中所述第一元素为所述目标波束的索引值，所述第二元素为所述目标配置信息。其中，第一元素和第二元素出现在第六列表的顺序不分先后。
例如，第六列表list6＝{1,info1}或list6＝{info1，1},第六列表中的第一元素对应的第三目标波束，其关联的第三目标配置信息为第六列表中的第二元素，即波束1的目标配置信息为info1。
又例如，list6＝{list7,info2},其中list7＝{1,2}，第六列表中的第一元素对应第三目标波束，其关联的第三目标配置信息为第六列表中的第二元素，即第三目标波束1，2的第三目标配置信息为info2。第一元素和第二元素出现在第六列表的顺序不分先后。即在本示例中，第六列表可以为list6＝{lnfo2，list7}。
