Description

无线通信方法、终端设备和网络设备 技术领域
本申请实施例涉及通信领域，并且更具体地，涉及无线通信方法、终端设备和网络设备。
背景技术
在新无线(New Radio，NR)系统中，考虑采用非地面通信网络(Non-Terrestrial Networks，NTN)向用户提供通信服务。
在引入NTN之后，当卫星高速移动时，卫星和地面网关的连接也要发生切换。具体而言，如果两个地面网关连接到两个地面基站或者一个地面基站下的两个小区，则针对该卫星覆盖的区域内所有用户设备(User Equipment，UE)，都需要在反馈链路切换(feeder link switch)后从原来的小区切换到新的小区内。但是，由于NNT中卫星与地面的距离较大，终端设备与卫星之间的信号传输时延也较大，此时如果通过无线资源管理(Radio Resource Management，RRM)测量的方式来获取信号质量，需要的等待时间会过长，进而有可能导致业务中断并降低了通信质量。
因此，针对NTN亟需一种能够快速接入新小区的方法。

终端设备110可以是任意终端设备，其包括但不限于与网络设备120或其它终端设备采用有线或者无线连接的终端设备。
例如，所述终端设备110可以指接入终端、用户设备(User Equipment，UE)、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。接入终端可以是蜂窝电话、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、可穿戴设备、5G网络中的终端设备或者未来演进网络中的终端设备等。
终端设备110可以用于设备到设备(Device to Device，D2D)的通信。
无线通信系统100还可以包括与基站进行通信的核心网设备130，该核心网设备130可以是5G核心网(5G Core，5GC)设备，例如，接入与移动性管理功能(Access and Mobility Management Function，AMF)，又例如，认证服务器功能(Authentication Server Function，AUSF)，又例如，用户面功能(User Plane Function，UPF)，又例如，会话管理功能(Session Management Function，SMF)。可选地，核心网络设备130也可以是LTE网络的分组核心演进(Evolved Packet Core，EPC)设备，例如，会话管理功能+核心网络的数据网关(Session Management Function+Core Packet Gateway，SMF+PGW-C)设备。应理解，SMF+PGW-C可以同时实现SMF和PGW-C所能实现的功能。在网络演进过程中，上述核心网设备也有可能叫其它名字，或者通过对核心网的功能进行划分形成新的网络实体，对此本申请实施例不做限制。
通信系统100中的各个功能单元之间还可以通过下一代网络(next generation，NG)接口建立连接实现通信。
例如，终端设备通过NR接口与接入网设备建立空口连接，用于传输用户面数据和控制面信令；终端设备可以通过NG接口1(简称N1)与AMF建立控制面信令连接；接入网设备例如下一代无线接入基站(gNB)，可以通过NG接口3(简称N3)与UPF建立用户面数据连接；接入网设备可以通过NG接口2(简称N2)与AMF建立控制面信令连接；UPF可以通过NG接口4(简称N4)与SMF建立控制面信令连接；UPF可以通过NG接口6(简称N6)与数据网络交互用户面数据；AMF可以通过NG接口11(简称N11)与SMF建立控制面信令连接；SMF可以通过NG接口7(简称N7)与PCF建立控制面信令连接。

在新无线(New Radio，NR)系统中，考虑采用非地面通信网络(Non-Terrestrial Networks，NTN)向用户提供通信服务。NTN一般采用卫星通信的方式向地面用户提供通信服务。相比地面蜂窝网通信，卫星通信具有很多独特的优点。首先，卫星通信不受用户地域的限制，例如一般的陆地通信不能覆盖海洋、高山、沙漠等无法搭设通信设备或由于人口稀少而不做通信覆盖的区域，而对于卫星通信来说，由于一颗卫星即可以覆盖较大的地面，加之卫星可以围绕地球做轨道运动，因此理论上地球上每一个角落都可以被卫星通信覆盖。其次，卫星通信有较大的社会价值。卫星通信在边远山区、贫穷落后的国家或地区都可以以较低的成本覆盖到，从而使这些地区的人们享受到先进的语音通信和移动互联网技术，有利于缩小与发达地区的数字鸿沟，促进这些地区的发展。再次，卫星通信距离远，且通信距离增大通讯的成本没有明显增加；最后，卫星通信的稳定性高，不受自然灾害的限制。
图2为本申请实施例提供的另一种通信系统的架构示意图。
如图2所示，包括终端设备1101和卫星1102，终端设备1101和卫星1102之间可以进行无线通信。终端设备1101和卫星1102之间所形成的网络还可以称为NTN。在图2所示的通信系统的架构中，卫星1102可以具有基站的功能，终端设备1101和卫星1102之间可以直接通信。在系统架构下，可以将卫星1102称为网络设备。在本申请的一些实施例中，通信系统中可以包括多个网络设备1102，并且每个网络设备1102的覆盖范围内可以包括其它数量的终端设备，本申请实施例对此不做限定。
图3为本申请实施例提供的另一种通信系统的架构示意图。
如图3所示，包括终端设备1201、卫星1202和基站1203，终端设备1201和卫星1202之间可以进行无线通信，卫星1202与基站1203之间可以通信。终端设备1201、卫星1202和基站1203之间所形成的网络还可以称为NTN。在图3所示的通信系统的架构中，卫星1202可以不具有基站的功能，终端设备1201和基站1203之间的通信需要通过卫星1202的中转。在该种系统架构下，可以将基站1203称为网络设备。在本申请的一些实施例中，通信系统中可以包括多个网络设备1203，并且每个网络设备1203的覆盖范围内可以包括其它数量的终端设备，本申请实施例对此不做限定。所述网络设备1203可以是图1中的网络设备120。
应理解，上述卫星1102或卫星1202包括但不限于：
低地球轨道(Low-Earth Orbit，)LEO卫星、中地球轨道(Medium-Earth Orbit，MEO)卫星、地球同步轨道(Geostationary Earth Orbit，GEO)卫星、高椭圆轨道(High Elliptical Orbit，HEO)卫 星等等。卫星可采用多波束覆盖地面，例如，一颗卫星可以形成几十甚至数百个波束来覆盖地面。换言之，一个卫星波束可以覆盖直径几十至上百公里的地面区域，以保证卫星的覆盖以及提升整个卫星通信系统的系统容量。
作为示例，LEO的高度范围可以为500km～1500km，相应轨道周期约可以为1.5小时～2小时，用户间单跳通信的信号传播延迟一般可小于20ms，最大卫星可视时间可以为20分钟，LEO的信号传播距离短且链路损耗少，对用户终端的发射功率要求不高。GEO的轨道高度可以35786km，围绕地球旋转周期可以24小时，用户间单跳通信的信号传播延迟一般可为250ms。
通常情况下，为了保证卫星的覆盖以及提升整个卫星通信系统的系统容量，卫星采用多波束覆盖地面，一颗卫星可以形成几十甚至数百个波束来覆盖地面；一个卫星波束可以覆盖直径几十至上百公里的地面区域。
需要说明的是，图1至图3只是以示例的形式示意本申请所适用的系统，当然，本申请实施例所示的方法还可以适用于其它系统。此外，本文中术语“系统”和“网络”在本文中常被可互换使用。本文中术语“和/或”，仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。另外，本文中字符“/”，一般表示前后关联对象是一种“或”的关系。还应理解，在本申请的实施例中提到的“指示”可以是直接指示，也可以是间接指示，还可以是表示具有关联关系。举例说明，A指示B，可以表示A直接指示B，例如B可以通过A获取；也可以表示A间接指示B，例如A指示C，B可以通过C获取；还可以表示A和B之间具有关联关系。
卫星从其提供的功能上可以分为透传转发(transparent payload)和再生转发(regenerative payload)两种。对于透传转发卫星，只提供无线频率滤波，频率转换和放大的功能，只提供信号的透明转发，不会改变其转发的波形信号。对于再生转发卫星，除了提供无线频率滤波，频率转换和放大的功能，还可以提供解调/解码，路由/转换，编码/调制的功能，其具有基站的部分或者全部功能。
在NTN中，可以包括一个或多个网关(Gateway)，用于卫星和终端之间的通信。
图4和图5分别示出了基于透传转发卫星和再生转发卫星的NTN场景的示意图。
如图4所示，对于基于透传转发卫星的NTN场景，网关和卫星之间通过馈线链路(Feeder link)进行通信，卫星和终端之间可以通过服务链路(service link)进行通信。如图5所示，对于基于再生转发卫星的NTN场景，卫星和卫星之间通过星间(InterStar link)进行通信，网关和卫星之间通过馈线链路(Feeder link)进行通信，卫星和终端之间可以通过服务链路(service link)进行通信。
随着人们对速率、延迟、高速移动性、能效的追求以及未来生活中业务的多样性、复杂性，3GPP国际标准组织开始研发5G。5G的主要应用场景包括：增强移动超宽带(Enhance Mobile Broadband，eMBB)、低时延高可靠通信(Ultra-Reliable and Low Latency Communication，URLLC)、大规模机器类通信(massive machine type of communication，mMTC)。其中，eMBB以用户获得多媒体内容、服务和数据为目标，其需求增长十分迅速。由于eMBB可能部署在不同的场景中。例如，室内，市区，农村等，其能力和需求的差别也比较大，所以不能一概而论，可以结合具体的部署场景详细分析。URLLC的典型应用包括：工业自动化，电力自动化，远程医疗操作(手术)，交通安全保障等。mMTC的典型特点包括：高连接密度，小数据量，时延不敏感业务，模块的低成本和长使用寿命等。
NR可以独立部署，5G网络环境中为了降低空口信令和快速恢复无线连接，快速恢复数据业务的目的，定了一个新的无线资源控制(Radio Resource Control，RRC)状态，即RRC_INACTIVE(去激活)状态。这种状态有别于RRC_IDLE(空闲)和RRC_CONNECTED(连接)状态。
在RRC_IDLE状态下：移动性为基于UE的小区选择重选，寻呼由核心网(Core Network，CN)发起，寻呼区域由CN配置。基站侧不存在UE接入层(Access Stratum，AS)上下文，也不存在RRC连接。
在RRC_CONNECTED状态下：存在RRC连接，基站和UE存在UE AS上下文。网络设备知道UE的位置是具体小区级别的。移动性是网络设备控制的移动性。UE和基站之间可以传输单播数据。
RRC_INACTIVE：移动性为基于UE的小区选择重选，存在CN-NR之间的连接，UE AS上下文存在某个基站上，寻呼由无线接入网(Radio Access Network，RAN)触发，基于RAN的寻呼区域由RAN管理，网络设备知道UE的位置是基于RAN的寻呼区域级别的。
为了便于对本申请方案的理解，下面对NR系统中的终端设备的小区选择和小区重选的方案进行说明。
1.小区选择过程。
小区需要满足S准则，当且仅当当前小区的接收功率和信号质量同时满足如下条件时，终端设备进行小区选择：Srxlev>0且Squal>0；具体地，终端设备可按照以下公式确定Srxlev和Squal：
Srxlev＝Q rxlevmeas–(Q rxlevmin+Q rxlevminoffset)–P compensation-Qoffset temp；
Squal＝Q qualmeas–(Q qualmin+Q qualminoffset)-Qoffset temp。
其中，Q rxlevmeas和Q qualmeas为UE测量的小区接收功率，即参考信号接收功率(Reference Signal Receiving Power，RSRP)和参考信号接收质量(Reference Signal Receiving Quality，RSRQ)；
Q rxlevmin和Q qualmin为网络侧要求的最小接收功率，即最小RSRP和最小RSRQ；
Q rxlevminoffset和Q qualminoffset为防止两个公共陆地移动网络(Public Land Mobile Network，PLMN)之间由于无线电环境波动产生的乒乓效应的偏移量。需要说明的是，仅当驻留在拜访PLMN合适的小区而周期性搜索更高优先级的PLMN时需要考虑的偏移量。
P compensation为功率补偿，例如当网络侧允许的最大发射功率大于UE自身能力决定的最大上行发射功率时，由于UE功率低导致的功率补偿。
Qoffset temp为仅用于特殊场景，正常情况不适用，例如“千叶问题”场景。
2.小区重选过程。
小区重选(cell reselection)指UE在空闲模式下通过监测邻区和当前小区的信号质量以选择一个最好的小区提供服务信号的过程。当邻区的信号质量及电平满足S准则且满足一定重选判决准则(R准则)时，终端将接入该小区驻留。UE成功驻留后，将持续进行本小区测量。具体地，终端设备通过RRC层根据RSRP测量结果计算S准则(Srxlev)，并将其与同频测量启动门限(Sintrasearch)和异频/异系统测量启动门限(Snonintrasearch)比较，作为是否启动邻区测量的判决条件。针对同频(Intra-frequency)和异频(inter-frequency)，网络设备通过配置每频率(per frequency)的同步信号和/或物理广播信道块(Synchronization Signal/PBCH Block，SSB)测量定时配置(SS/PBCH block measurement timing configuration，SMTC)辅助UE进行测量，达到UE省电目的。
针对小区信号质量的获取过程，终端设备可以通过系统广播获取每频率(per frequency)的参数N和门限，用于选择最好波束(beam)。由此，终端设备可将满足门限的最好的前N个波束的信号质量线性平均作为小区信号质量。如果没有广播每频率(per frequency)的参数N和门限，则将小区中最好波束的信号质量作为小区信号质量。
针对目标小区选择的过程，终端设备可通过到最好小区范围(rangeToBestCell)控制候选的小区，即与最好小区信号质量的差在最好小区范围(rangeToBestCell)内的所有候选小区中，选择满足门限的波束最多的小区作为目标小区。具体地，按照以下公式计算R n和R s，如果连续测得的R n和R s能够在检测时间内都保持R n>R s，则需要进行小区重选。
R s＝Q meas,s+Q hyst-Qoffset temp；
R n＝Q meas,n-Qoffset–Qoffset temp。
其中，R s表示服务小区的信号质量；
R n表示邻小区的信号质量；
Q meas表示在小区重选中使用的RSRP测量值(RSRP measurement quantity used in cell reselections)；
Q meas,s表示服务小区RSRP测量值；
Q meas,n表示邻小区RSRP测量值；
Q hysts为小区重选迟滞；
针对同频：如果Qoffset s,n是有效的，则Qoffset等于Qoffset s,n，否则等于0(For intra-frequency:Equals to Qoffset s,n,if Qoffset s,n is valid,otherwise this equals to zero)；
针对异频：如果Qoffset s,n是有效的，等于Qoffset s,n加上Qoffset frequency，否则等于Qoffset frequency(For inter-frequency:Equals to Qoffset s,n plus Qoffset frequency,if Qoffset s,n is valid,otherwise this equals to Qoffset frequency.)。
Qoffset s,n为两个小区(即服务小区和邻小区)接收信号质量要求的差值。
Qoffset temp表示小区的临时偏移值(Offset temporarily applied to a cell)。
在引入NTN之后，当卫星高速移动时，卫星和地面网关的连接也要发生切换。具体而言，如果两个地面网关连接到两个地面基站或者一个地面基站下的两个小区，则针对该卫星覆盖的区域内所有用户设备(User Equipment，UE)，都需要在反馈链路切换(feeder link switch)后从原来的小区切换到新的小区内。但是，由于NNT中卫星与地面的距离较大，终端设备与卫星之间的信号传输时延也较大，此时如果通过无线资源管理(Radio Resource Management，RRM)测量的方式来获取信号质量，需要的等待时间会过长，进而有可能导致业务中断并降低了通信质量。当然，如果两个地面网关连接到同一个基站下的同一个小区，UE可以不进行切换操作。
图6是本申请实施例提供的卫星和地面网关的连接发生切换的场景的一个示例。
如图6所示，地面网关1连接至基站1，地面网关2连接至基站2。在T1时刻，卫星覆盖的区域 为基站1下的小区，在T2时刻，卫星覆盖的区域为基站2下面的小区，此时，需要进行馈线链路切换(feeder link switch)，即需要进行小区切换，使得终端设备可以从原来的小区切换到新的小区内。例如，可通过切换阈值(Transition threshold)从原来的小区切换到新的小区内。该切换阈值可以是小区选择或小区重选中相关的阈值。
本申请实施例中，提供引入第一调整量辅助终端设备进行小区选择或小区重选，由于在一段时间内卫星小区的地面覆盖是固定的(quasi-earth-fixed)，基于此，可通过这段时间的一个调整量快速获取终端设备的新小区信号质量，进而基于终端设备的新小区信号质量进行小区选择和/或小区重选，能够避免在到达小区后基于RRM测量进行小区选择和/或小区重选，有利于终端设备快速接入新小区，进而能够减小业务中断并提升通信质量。
图7示出了根据本申请实施例的无线通信方法200的示意性流程图，所述方法200可以由终端设备执行。例如可以是如图1所示的终端设备。
如图7所示，所述方法200可包括以下部分或全部内容：
S210，基于第一调整量进行小区选择和/或小区重选；
其中，所述第一调整量用于表征新小区到达时终端设备的新小区信号质量相比服务小区离开时或所述新小区到达时所述终端设备的服务小区信号质量的调整量。
针对NTN，终端设备基于第一调整量进行小区选择和/或小区重选。例如，终端设备基于所述第一调整量确定出终端设备的新小区信号质量，进而基于所述终端设备的新小区信号质量进行小区选择和/或小区重选。
本申请实施例中，通过引入第一调整量，能够直接基于所述第一调整量确定出终端设备的新小区信号质量，进而基于所述终端设备的新小区信号质量进行小区选择和/或小区重选，避免了新小区到达后先基于RRM测量终端设备的新小区信号质量，然后基于所述终端设备的新小区信号质量进行小区选择和/或小区重选，即避免了通过RRM测量来获取信号质量的等待时间；相当于，通过引入所述第一调整量，能够缩短获取新小区信号质量的等待时间，可以使得终端更早的获得终端设备的新小区信号质量，进而使得终端能够更早接入新小区，减少业务中断并提升通信质量。
需要说明的是，本申请实施例中，新小区到达时终端设备的新小区信号质量可以理解为：新小区到达时所述终端设备在所述新小区中的信号质量，服务小区离开时或所述新小区到达时所述终端设备的服务小区信号质量可以理解为：所述服务小区离开时或所述新小区到达时所述终端设备在服务小区中的信号质量。还需要说明的是，本申请实施例中，对新小区信号质量和服务小区信号质量的具体实现方式不作限定。例如，可以是RSRP，也可以是RSRQ，还可以是SINR。当然，在本申请的其他可替代实施例中，所述第一调整量还可用于表征新小区到达时终端设备的新小区信号质量相比服务小区即将离开时所述终端设备的服务小区信号质量的调整量。可选的，服务小区即将离开可以理解为新小区已到达且服务小区即将离开。例如，作为一种典型的情况，所述服务小区即将离开的时刻可以是新小区达到的时刻。
在一些实施例中，所述第一调整量用于表征所述新小区到达时所述终端设备的新小区信号质量相比所述服务小区离开时所述终端设备的服务小区信号质量的调整量；基于此，获取所述服务小区离开时所述终端设备的第一服务小区信号质量；将所述第一服务小区信号质量、所述第一调整量以及路损差异之和，确定为所述新小区到达时所述终端设备的新小区信号质量；所述路损差异为所述新小区到达时所述终端设备的服务链路的路损相比所述服务小区离开时所述终端设备的服务链路的路损的差异；基于所述新小区到达时所述终端设备的新小区信号质量，进行小区选择和/或小区重选。
换言之，假设服务小区离开的时刻为T1时刻，所述新小区的到达时刻为T2时刻，本申请实施例中，所述第一调整量为所述终端设备在T2时刻的新小区信号质量相对所述终端设备在T1时刻的服务小区信号质量。
在一种实现方式中，所述新小区到达的时刻位于所述服务小区离开的时刻之后。
换言之，假设服务小区离开的时刻为T1时刻，所述新小区的到达时刻为T2时刻，则T1＜T2。或者说，所述终端设备断开与旧小区的连接后再与所述新小区建立连接。
在一种实现方式中，所述方法200还可包括：
基于以下中的至少一项确定所述路损差异：
所述终端设备的位置信息、星历信息、所述新小区到达的时间信息以及所述服务小区离开的时间信息。
例如，所述终端设备根据所述终端设备的位置信息、星历信息、所述新小区到达的时间信息以及所述服务小区离开的时间信息，确定所述路损差异。具体地，所述终端设备可基于所述新小区到达的时间信息，在所述新小区到达的时刻，基于所述终端设备的位置信息和星历信息，确定所述终端设备 在所述新小区到达时所述终端设备的服务链路的路损；类似的，所述终端设备可基于所述服务小区离开的时间信息，在所述服务小区离开的时刻，基于所述终端设备的位置信息和星历信息，确定所述终端设备在所述服务小区离开时所述终端设备的服务链路的路损；进而，所述终端设备可基于所述新小区到达时所述终端设备的服务链路的路损和所述服务小区离开时所述终端设备的服务链路的路损，确定所述路损差异。例如，所述终端设备可将所述新小区到达时所述终端设备的服务链路的路损和所述服务小区离开时所述终端设备的服务链路的路损的差值，确定所述路损差异。
在一种实现方式中，所述方法200还可包括：
所述服务小区离开时启动邻区测量。
换言之，所述终端设备在所述新小区到达时可基于所述第一调整量进行小区选择和/或小区重选，所述终端设备在所述服务小区离开时也可启动邻区测量，并基于测量结果进行选择和/或小区重选。这两种方案可结合使用，也可单独使用，本申请对此不作具体限定。
在一些实施例中，所述第一调整量用于表征所述新小区到达时所述终端设备的新小区信号质量相比所述新小区到达时所述终端设备的服务小区信号质量的调整量；基于此，获取所述新小区到达时所述终端设备的第二服务小区信号质量；将所述第二服务小区信号质量和所述第一调整量之和，确定为所述新小区到达时所述终端设备的新小区信号质量；基于所述新小区到达时所述终端设备的新小区信号质量，进行小区选择和/或小区重选。
换言之，假设服务小区离开的时刻为T1时刻，所述新小区的到达时刻为T2时刻，本申请实施例中，所述第一调整量为所述终端设备在T2时刻的新小区信号质量相对所述终端设备在T2时刻的服务小区信号质量。
在一种实现方式中，所述新小区到达的时刻位于所述服务小区离开的时刻之前。
换言之，假设服务小区离开的时刻为T1时刻，所述新小区的到达时刻为T2时刻，则T1＞T2。或者说，所述终端设备与所述新小区建立连接后再断开与旧小区的连接。
在一种实现方式中，基于所述新小区到达时所述终端设备的新小区信号质量，在小区选择和/或小区重选的排序操作中，排除所述服务小区。
由于T1＞T2，相当于，所述终端设备在与所述新小区建立连接后再断开与旧小区的连接，因此，在小区选择或小区重选的重排序过程中，通常也会考虑即将离开的服务小区。本申请实施例中，在小区选择或小区重选中，通过排除即将离开的服务小区，可以更早的通过信号质量排序接入到新小区，避免终端设备在旧的服务小区上产生业务中断。
在一些实施例中，所述方法200还可包括：
接收所述服务小区的配置信息，所述配置信息包括所述第一调整量。

在一种实现方式中，所述配置信息适用于馈线链路发生切换(feeder link switch)的场景。
换言之，在馈线链路发生切换的情况下，基于所述第一调整量进行小区选择和/或小区重选。
在一种实现方式中，所述新小区包括多个小区，所述多个小区中的部分小区或全部小区的到达时刻相同，或所述多个小区的到达时刻互不相同。
换言之，所述第一调整量可包括多个调整量，所述多个调整量和所述多个小区一一对应；或者，所述多个小区中不同到达时刻的小区对应不同的调整量。基于此，所述终端设备可基于每一个小区达到时的小区信号质量，进行小区选择和/或小区重选。
在一种实现方式中，所述第一调整量包括以下中的至少一项：所述新小区到达时馈线链路的路损相比所述服务小区离开时馈线链路的路损的差异、所述新小区到达时的同步信号和/或物理广播信道块SSB发送功率相比所述服务小区离开时的SSB发送功率的差异、或所述新小区到达时的卫星功率放大倍数相比所述服务小区离开时的卫星功率放大倍数的差异。例如，所述第一调整量包括以下差异之和：所述新小区到达时馈线链路的路损相比所述服务小区离开时馈线链路的路损的差异、所述新小区到达时的同步信号和/或物理广播信道块SSB发送功率相比所述服务小区离开时的SSB发送功率的差异、或所述新小区到达时的卫星功率放大倍数相比所述服务小区离开时的卫星功率放大倍数的差异。
换言之，假设服务小区离开的时刻为T1时刻，所述新小区的到达时刻为T2时刻，本申请实施例中，针对T1时刻，终端设备的信号质量可通过以下公式计算得到：P T1＝P SSB,1-P service,1-P feeder,1+P Satellite,1； 其中，P SSB,1表示T1时刻下基站的SSB发送功率，P feeder,1表示T1时刻下馈线链路的路损，P Satellite,1表示T1时刻下卫星功率放大倍数；P service,1表示T1时刻下服务链路的路损。针对T2时刻，终端设备的信号质量可通过以下公式计算得到：P T2＝P SSB,2-P service,2-P feeder,2+P Satellite,2；其中，P SSB,2表示T2时刻下基站的SSB发送功率，P feeder,2表示T2时刻下馈线链路的路损，P Satellite,2表示T2时刻下卫星功率放大倍数；P service,2表示T2时刻下服务链路的路损。基于此，可以得到：
P T2-P T1＝(P SSB,2-P SSB,1)-(P service,2-P service,1)-(P feeder,2-P feeder,1)+(P Satellite,2-P Satellite,1)；
本申请实施例中，所述第一调整量可包括(P SSB,2-P SSB,1)、(P feeder,2-P feeder,1)以及(P Satellite,2-P Satellite,1)。
图8是本申请实施例提供的卫星和地面网关的连接发生切换的场景的另一个示例。
如图8所示，网关1连接至基站1，网关2连接至基站2。假设卫星按照如图所示的卫星移动方向(Satellite moving direction)进行移动，服务小区离开的时刻为T1时刻，所述新小区的到达时刻为T2时刻。换言之，在T1时刻，卫星覆盖的区域为基站1下的小区，在T2时刻，卫星覆盖的区域为基站2下面的小区，此时，需要进行馈线链路切换(feeder link switch)，即需要进行小区切换，使得终端设备可以从原来的小区切换到新的小区内。
下面以图8所示的场景为例，结合具体实施例对本申请的方案进行示例性说明。
实施例1：
本申请实施例中，网络广播新小区到达的时间信息的同时，附加广播到新小区到达时终端设备的新小区信号质量相比服务小区开始时终端设备的服务小区信号质量的调整量，通过调整量进行小区选择和/或小区重选(T1<T2)。
终端设备接收服务小区的配置信息，所述配置信息还包括所述服务小区离开的时间信息T1和/或所述新小区到达的时间信息T2。进一步的包含，新小区到达时终端设备的新小区信号质量相比服务小区开始时终端设备的服务小区信号质量的调整量。具体的：
a)、配置信息可以通过系统消息或RRC专用信令获取；
b)、配置信息针对馈线链路切换(feeder link switch)场景；
c)、新小区可能有多个小区，所述多个小区的T2可以相同，也可以不同；
d)、调整量可能包括新旧小区馈线链路路损差异，和/或新旧小区SSB发送功率差异，和/或新旧小区卫星功率放大倍数的差异等。
T1时刻服务小区离开，终端设备将T1时刻服务小区信号质量(例如RSRP/RSRQ/SINR)加上网络配置的新小区到达时终端设备的新小区信号质量相比服务小区开始时终端设备的服务小区信号质量的调整量，再叠加上T2时刻与T1时刻相比服务链路的路损差异(通过终端设备位置和星历信息计算)，作为T2时刻下终端设备的新小区信号质量，并在T2时刻使用所述终端设备的新小区信号质量进行小区选择或小区重选过程中的排序操作。此外，在T1时刻，即服务小区离开时，终端设备还可以启动同频/异频上的邻区测量。
本申请实施例中，通过引入调整量的配置后，T2时刻下的终端设备可以尽快获得新小区信号质量，避免了T2时刻开始测量新小区然后才能获得终端设备的新小区信号质量，缩短了终端设备的新小区信号质量的获取时间，使得终端设备更快接入小区，减少了业务中断时间并提升了通信质量。
实施例2：
网络广播新小区到达的时间信息的同时，附加广播到新小区到达时终端设备的新小区信号质量相比新小区达到时终端设备的服务小区信号质量的调整量，终端设备在新小区到达时通过所述调整量进行小区选择和/或小区重选，并在排序时排除即将离开的服务小区(T1>T2)。
终端设备接收服务小区的配置信息，所述配置信息还包括所述服务小区离开的时间信息T1和/或所述新小区到达的时间信息T2。进一步的包含，新小区到达时终端设备的新小区信号质量相比服务小区开始时终端设备的服务小区信号质量的调整量。具体的：
a)、配置信息可以通过系统消息或RRC专用信令获取；
b)、配置信息针对馈线链路切换(feeder link switch)场景；
c)、新小区可能有多个小区，所述多个小区的T2可以相同，也可以不同；
d)、调整量可能包括新旧小区馈线链路路损差异，和/或新旧小区SSB发送功率差异，和/或新旧小区卫星功率放大倍数的差异等。
T2时刻新小区到达时，终端设备将T2时刻服务小区信号质量(例如RSRP/RSRQ/SINR)加上网络配置的新小区到达时终端设备的新小区信号质量相比新小区达到时终端设备的服务小区信号质量的调整量，作为T2时刻终端设备的新小区信号质量，并在T2时刻使用所述终端设备的新小区信号质量进行小区选择或小区重选过程中的排序操作。在小区重选排序中，终端设备将即将离开的服务小区排除掉。
本申请实施例中，通过引入的调整量获取T2时刻新小区信号质量，可以加快重选到新小区；此 外，通过排除即将离开的服务小区，可以更早的通过信号质量排序接入到新小区，避免终端设备在旧的服务小区上产生业务中断。
综上所述，本申请提供了一种NTN场景下小区选择和/或小区重选的方法，主要针对馈线链路切换场景。在一些实施例中，网络广播新小区到达的时间信息的同时，附加广播到新小区到达时终端设备的新小区信号质量相比服务小区开始时终端设备的服务小区信号质量的调整量，通过调整量进行小区选择和/或小区重选(T1<T2)。在另一些实施例中，网络广播新小区到达的时间信息的同时，附加广播到新小区到达时终端设备的新小区信号质量相比新小区达到时终端设备的服务小区信号质量的调整量，终端设备在新小区到达时通过所述调整量进行小区选择和/或小区重选，并在排序时排除即将离开的服务小区(T1>T2)。本申请实施例中，通过引入调整量的配置后，T2时刻下的终端设备可以尽快获得新小区信号质量，避免了T2时刻开始测量新小区然后才能获得终端设备的新小区信号质量，缩短了终端设备的新小区信号质量的获取时间，使得终端设备更快接入小区，减少了业务中断时间并提升了通信质量。
