为便于更好的理解本申请实施例，对本申请相关的测量进行说明。
终端设备的测量过程一般用于获取被测量对象的信号测量结果，信号测量结果评价指标包括被测量对象的参考信号接收功率(Reference Signal Received Power，RSRP)、参考信号接收质量(Reference Signal Received Quality，RSRQ)或信噪比(Signal to Interference plus Noise Ratio，SINR)测量结果。
对于连接态的终端设备，为了让处于连接态的终端设备有选择性的执行测量过程，网络侧通常会通过专用信令给终端设备配置一个或者多个测量目标(Measurement  Object，MO)，每一个MO配置信息中包含一个目标频点的信息，或者，一个MO配置信息中可以同时包含一个目标频点的信息以及与该目标频点关联的物理小区标识(Physical Cell Identity，PCI)列表信息。终端识别一个小区需要同时确定小区对应的频点和PCI信息，但由于NR PCI也就1008种，在MO配置信息仅包含目标频点信息时，终端设备也可以通过PCI遍历的方法搜索到目标小区；只不过网络侧同时告知终端设备测量对象的频点和PCI列表信息就可以加快终端设计进行小区搜索。
对于空闲态或者非激活态的终端设备，执行测量的目的一般就是为了获取至少一个邻区的信号测量结果从而控制终端设备服务小区选择/重选过程。与连接态通过专用信令配置测量对象配置信息不同，处于空闲态或者非激活态的终端设备与网络侧没有建立RRC连接，这种情况下通过小区系统广播消息或者终端设备上次离开连接态收到的连接释放消息中获取测量对象配置信息。测量对象配置信息的内容和连接态的MO配置信息类似，也是包含一个目标频点的信息或者包含一个目标频点的信息和与该目标频点关联的PCI列表信息。
为便于更好的理解本申请实施例，对本申请相关的切换进行说明。
切换过程是网络侧触发的行为，终端设备直到收到网络侧发送的同步重配消息或者条件同步重配消息获知正在执行切换流程，收到同步重配消息后或者配置的条件同步重配事件触发时，终端设备会马上应用同步重配消息或者条件同步重配消息中包含的配置信息向切换目标小区发起接入流程。通常网络侧发送的同步重配消息或者条件同步重配消息中包含切换目标小区的配置信息，比如切换目标小区服务频点信息，终端设备在接入切换目标小区之前，首先需要完成与切换目标小区的下行同步，终端完成与切换目标小区的下行同步过程需要使用切换目标小区服务频点信息。
为便于更好的理解本申请实施例，对本申请相关的重定向进行说明。
重定向过程中，网络侧通过连接释放消息为终端设备配置重定向配置信息，重定向功能的目标主要是为了实现网络负载均衡，将终端设备选择性的释放到支持特定频点的小区上。重定向配置信息通常包括重定向目标频点信息，获取重定向配置信息后，终端按照重定向配置信息指示驻留到支持对应频点的小区上。
为便于更好的理解本申请实施例，对本申请相关的卫星小区进行说明。
卫星可以分为地球同步轨道(Geostationary Earth Orbiting，GEO)、中轨道(Medium Earth Orbiting，MEO)或低轨道(Low Earth Orbiting，LEO)。其中GEO覆盖范围大(通常3颗卫星覆盖全球)，且相对地面静止，终端设备进行移动性测量的机会非常少，终端设备复用地面测量上报规则基本可以工作；但是对于MEO或LEO，由于卫星相对地面高速移动(LEO一般对地速度可以达到7.8公里每秒，一个LEO卫星提供的有效服务时长也就是几秒到几十秒)，终端设备必须快速完成测量上报才能减少脱网的风险。
进一步地，在卫星小区信号为低频频段FR1的信号时，终端设备大多使用全向天线，能够比较迅速的接收卫星小区信号；在卫星小区信号为高频频段FR2信号时，为了抵消高频信号严重的衰减特性，终端设备大多使用定向天线接收信号，此时，卫星的高速移动使得终端设备使用定向天线捕获卫星小区信号的难度大大增加，在没有额外辅助信息下，终端设备使用定向天线实现卫星小区信号的快速测量基本难以实现。
为便于更好的理解本申请实施例，对本申请相关的透明转发卫星链路之间传播时延差进行说明。
A表示信关站(基本等价于基站)，S1表示卫星1，S2表示卫星2，U点表示终端的位置，A-S1-U实线表示信关站经卫星1转发与终端通信的信号链路，用L1表示；A-S2-U虚线表示信关站经卫星2转发与终端通信的信号链路，用L2表示，不同于地面系统，L1和L2距离差异可能非常大，可达0到几千公里，换句话说，两条卫星信号转发链路造成的传播时延差异可达0到几十ms(电磁波在空气中的传播速度大约为300公里/ms)，这样的传播时延差异甚至大于SMTC配置窗口(最大5ms)/测量间隔窗口(最大6ms)， 而且不同终端所处的地理位置不同，经历的卫星间传播时延差异也不同。
需要说明的是，对于透明转发卫星，终端与卫星之间的链路叫做服务链路；信关站与卫星之间的链路叫做馈电链路。
对于信号搜索时延敏感的场景，比如：LEO/MEO场景，简单复用地面信号搜索机制是不合适的。比如卫星通信系统，卫星的高速移动导致了终端捕获卫星信号的难度相比地面系统大大增加，如果终端进一步使用定向天线，在没有额外辅助信息下，终端使用定向天线实现高速移动卫星小区信号的跟踪搜索是十分困难的，严重时，终端会有脱网风险。
基于上述问题，本申请提出了一种搜索信号的方案，终端设备能够根据目标频点关联的星历信息、用于调整目标频点关联的SMTC配置窗口的参考信息、目标频点关联的小区位置或者方位信息中的至少一种在目标频点搜索信号，从而降低信号搜索时延，提升系统性能。
以下通过具体实施例详述本申请的技术方案。
图3是根据本申请实施例的无线通信的方法300的示意性流程图，如图3所示，该方法300可以包括如下内容中的至少部分内容：
S310，网络设备向终端设备发送第一信息，该第一信息用于终端设备在目标频点搜索信号，且该第一信息包括以下至少之一：
目标频点关联的星历信息，
用于调整目标频点关联的SMTC配置窗口的参考信息，
目标频点关联的小区位置或者方位信息；
S320，终端设备接收该第一信息。
在本申请实施例中，终端设备可以基于目标频点关联的星历信息，获知目标频点关联卫星的位置和方向；终端设备也可以基于用于调整目标频点关联的SMTC配置窗口的参考信息，获知SMTC窗口的时域位置。从而，终端设备在目标频点搜索信号时，可结合目标频点关联卫星的位置和方向、SMTC窗口的时域位置、目标频点关联的小区位置或者方位信息中的至少一种，在目标频点进行信号搜索，从而可以快速且精准的进行信号搜索，降低信号搜索时延，同时也可以避免由于测量不及时而带来的脱网风险。
需要说明的是，目标频点可以关联一颗或多颗卫星。示例性的，目标频点关联卫星可以是服务卫星的邻卫星，此外，一颗服务卫星可以关联一颗或者多颗邻卫星。上述第一信息中包括的星历信息可以是与目标频点关联的一颗特定的卫星对应的星历信息，或者，上述第一信息中包括的星历信息可以是与目标频点关联的任意一颗卫星对应的星历信息，或者，上述第一信息中包括的星历信息可以是与目标频点关联的所有卫星对应的星历信息。
应理解，小区位置或者方位信息中，小区位置信息可以用于表示小区的地理位置坐标，小区方位信息可以用于表示小区的方向。
在一些实施例中，本申请可以应用于信号搜索时延敏感的场景，例如信号载体快速移动场景(如LEO/MEO场景)、高频信号场景、测量耗时需求敏感型场景等。
在一些实施例中，上述第一信息还包括但不限于以下至少之一：
目标频点的信息；
目标频点关联的PCI列表信息；
目标频点关联的SMTC信息；
目标频点关联的子载波间隔(Subcarrier spacing，SCS)信息；
目标频点关联的频段信息。
其中，目标频点的信息可以是目标频点或者用于表示该目标频点的标识或索引，或者，目标频点的信息可以是目标频点的配置信息。
在一些实施例中，在第一信息不包括目标频点的信息时，目标频点的信息为预配置 或者协议约定的；在第一信息包括用于调整目标频点关联的SMTC配置窗口的参考信息，且不包括目标频点关联的SMTC信息时，该目标频点关联的SMTC信息为预配置或者协议约定的。
在一些实施例中，上述用于调整目标频点关联的SMTC配置窗口的参考信息包括以下至少之一：
终端设备的服务卫星与目标频点关联卫星的馈电链路信号传播时延差异量信息；
终端设备的服务卫星与目标频点关联卫星的馈电链路信号传播时延差异量随时间的变化率信息；
基准参考点信息；
终端设备的服务小区和目标频点关联的小区分别到基准参考点的链路信号传播时延差异量信息；
终端设备的服务小区和目标频点关联的小区分别到基准参考点的链路信号传播时延差异量随时间的变化率信息；
目标频点关联的SMTC信息随时间的变化率信息。
需要说明的是，上述馈电链路信号传播时延差异量信息即为终端设备的服务卫星的馈电链路信号传播时延与目标频点关联卫星的馈电链路信号传播时延之间的差异量。终端设备的服务卫星的馈电链路信号可以是指：终端设备的服务卫星与信关站之间的链路上传输的信号。目标频点关联卫星的馈电链路信号可以是指：目标频点关联卫星与信关站之间的链路上传输的信号。
在一些实施例中，在用于调整目标频点关联的SMTC配置窗口的参考信息不包括基准参考点信息时，基准参考点信息可以是预配置或者协议约定的。
在一些实施例中，基准参考点信息例如可以是基准参考点的坐标或位置，或者，基准参考点信息例如可以是用于指示基准参考点的坐标或位置的信息。
在一些实施例中，上述变化率信息的时间参考点为预配置或协议约定的，或者，上述变化率信息的时间参考点为网络设备通过该第一信息配置的。
在一些实施例中，目标频点关联的星历信息包括以下至少一种：
星历数据信息、星历数据信息对应的索引或标识信息。
本申请实施例中的星历数据与卫星通信领域常用的卫星轨道运行数据与星历图(Ephemeris)意思类似。总的来讲星历图的含义就是告知使用方在某一定义的时间起点时卫星的初始位置状态矢量信息，通常时间起点信息是公共的，不用单独与某一颗卫星绑定，剩下需要6个参数表征一个卫星轨道运行数据，其中卫星的绝对空间位置矢量需要三个参数表示，卫星的空间速度矢量需要三个参数表示。那么获得了一个卫星的轨道运行数据后，理论上讲，该卫星在未来任何时间点的空间位置信息都是可精准计算并预测的。
在一些实施例中，星历数据可以与一种索引标识信息关联。如显性索引方法：一个星历数据与一个索引标识关联，简单来讲就是给一个星历数据取一个简单的名字，方便通过名字使用对应星历数据，如表1所示。又如隐式索引方法：所有星历数据形成一个列表，一个星历数据与该星历数据在该列表的元素位置编号值关联，如表2所示。
表1
索引标识1 索引标识2 …… 索引标识N
星历数据1 星历数据2 …… 星历数据N
上述表1中一个星历数据与一个索引标识关联，通常索引标识占用的比特数较少，使用索引标识比使用星历数据更节省系统开销。
表2
列表元素位置编号1 列表元素位置编号2 …… 列表元素位置编号M
星历数据1 星历数据2 …… 星历数据M
上述表2中一个星历数据与该星历数据在该列表的元素位置编号值关联，通常列表元素位置编号取值从0或者1开始，使用列表元素位置编号信息比使用星历数据更节省系统开销。
需要说明的是，上述表1至表2中的参数N和M为正整数，且N≥1，M≥1。
在一些实施例中，目标频点关联的星历信息是按照频点粒度或PCI粒度配置的。
例如，目标频点关联的星历信息按照频点粒度配置可以如表3所示。
表3
频点信息1 频点信息2 …… 频点信息N
星历信息1 星历信息2 …… 星历信息N
上述表3中每一个频点信息关联一套星历信息。表3中参数N为正整数，且N≥1。
又例如，目标频点的星历信息按照PCI粒度配置可以如表4所示。
表4
Figure PCTCN2021078201-appb-000001
上述表4中每一个频点信息关联至少一个PCI信息，每一个PCI信息直接关联一套星历信息，星历相关配置信息按照PCI粒度配置。
在一些实施例中，第一信息由以下之一承载：系统广播消息、专用信令。
示例性的，可以是通过切换配置消息、同步重配配置消息、重定向配置消息、测量配置消息中的任意一种承载该第一信息。
基于上述实施例，对终端设备如何基于第一信息在目标频点搜索信号，进行如下示例性的说明。
示例一、MEO或LEO相对地面高速移动，尤其对于使用定向天线的终端设备，网络侧配置的频点信息不足以让终端设备快速搜索到目标频点关联的卫星所产生或者转发的信号，而获知目标频点关联的星历信息之后，终端设备可以快速转动天线并使其对准目标频点关联卫星的所在空域，从而实现卫星信号的快速搜索，避免终端搜索信号不及时带来的脱网风险。
假设上述用于调整目标频点关联的SMTC配置窗口的参考信息包括的信息分别对应配置1至配置7。例如，配置1为终端设备的服务卫星与目标频点关联卫星的馈电链路信号传播时延差异量信息；配置2为终端设备的服务卫星与目标频点关联卫星的馈电链路信号传播时延差异量随时间的变化率信息；配置3为基准参考点信息；配置4为终端设备的服务小区和目标频点关联的小区分别到基准参考点的链路信号传播时延差异量信息；配置5为终端设备的服务小区和目标频点关联的小区分别到基准参考点的链路信号传播时延差异量随时间的变化率信息；配置6为目标频点关联的SMTC信息随时间的变化率信息；配置7为变化率信息关联的时间参考点。
示例二、对于配置1单独使用场景，如果终端设备的服务卫星与目标频点关联卫星的馈电链路信号传播时延差异量在短时间内变化不大(或者近似不变)，则终端设备结合目标频点关联的SMTC信息以及终端设备的服务卫星与目标频点关联卫星的馈电链路信号传播时延差异量信息，就能获取目标频点关联的SMTC窗口的实际时域位置，进而在目标频点搜索信号。
示例三、对于配置2单独使用场景，如果终端设备的服务卫星与目标频点关联卫星的馈电链路信号传播时延差异量随时间的变化情况可预测，那么将终端设备的服务卫星与目标频点关联卫星的馈电链路信号传播时延差异量随时间的变化率信息告知终端设 备，则终端设备结合目标频点关联的SMTC信息以及终端设备的服务卫星与目标频点关联卫星的馈电链路信号传播时延差异量随时间的变化率信息，就能获取目标频点关联的SMTC窗口的实际时域位置，进而在目标频点搜索信号。示例三中的变化率信息可以是预配置或者协议约定的，或者，以默认配置作为基准，该默认配置可以是目标频点关联的SMTC信息或者其他公共配置信息。
示例四、对于配置1和配置2结合使用场景，配置2所述的变化率信息以配置1为基准，终端设备结合目标频点关联的SMTC信息、配置1以及配置2就能获取目标搜索频点关联的SMTC窗口的实际时域位置，进而在目标频点搜索信号。
示例五、配置4和配置5使用场景描述与配置1和配置2类似，也包括配置4单独使用场景、配置5单独使用场景、配置4和配置5结合使用场景，此时配置4和配置5中提到的基准参考点是默认知晓的，不用网络侧显性配置；对于配置3显性配置场景，又可以分为配置3和配置4结合使用场景，配置3和配置5结合使用场景，配置3、配置4和配置5结合使用场景，具体的辅助终端调整目标频点关联的SMTC窗口的实际时域位置，思路与配置1和配置2场景类似，这里不再赘述。
示例六、对于配置6单独使用场景，如果目标频点关联的SMTC信息随时间的变化情况可预测，则终端结合目标频点关联的SMTC信息以及配置6就能获取目标频点关联的SMTC窗口的实际时域位置，进而在目标频点搜索信号。
需要说明的是，配置2、配置5和配置6中提到的变化率信息需要关联一个时间参考点信息时，可以配置上述配置7；否则，配置2、配置5和配置6中提到的变化率信息使用一个公共的默认时间参考点信息。
因此，在本申请实施例中，终端设备能够根据目标频点关联的星历信息、用于调整目标频点关联的SMTC配置窗口的参考信息、目标频点关联的小区位置或者方位信息中的至少一种在目标频点搜索信号，从而可以快速且精准的进行信号搜索，降低信号搜索时延，同时也可以避免由于测量不及时而带来的脱网风险。
