Description

本发明涉及移动通信技术，尤其涉及一种无线通信方法、终端设备、网络设备及存储介质。
背景技术
非地面通信网络(Non Terrestrial Network，NTN)用通信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，通信卫星通信具有很多独特的优点，比如：不受用户地域限制、通信距离远、稳定性高等。但是，由于参考信号接收功率(Reference Signal Receiving Power，RSRP)测量值不能准确的反应小区边缘和小区中心的差异，导致传统的基于RSRP门限的终端不位于小区边缘(not-cell-edge)准则不能准确的刻画终端设备(User Equipment，UE)在小区的位置，例如，当UE的RSRP值低于所述RSRP门限，由于RSRP测量精度的问题，UE可能处于小区中心位置，此时如果执行放松测量，则会增加UE功耗；类似的，如果UE的RSRP值高于所述RSRP门限，实际上UE可能处于小区边缘，此时，按照终端不位于小区边缘准则，UE可能没有执行测量，这样可能对终端的移动性性能造成影响，例如导致过迟的小区重选。

具体实施方式
为了能够更加详尽地了解本发明实施例的特点和技术内容，下面结合附图对本发明实施例的实现进行详细阐述，所附附图仅供参考说明之用，并非用来限定本发明实施例。
在对本发明实施例提供的无线通信方法进行详细说明之前，先对地面蜂窝网通信中测量放松和NTN进行简要说明。
测量放松
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，为此，第三代合作伙伴计划(3 rd Generation Partnership Project，3GPP)国际标准组织开始研发第5代(5th generation，5G)。5G的主要应用场景包括：增强移动超宽带(Enhanced 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 MachineType Communication，mMTC)。
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，定义一个新的无线资源控制(Radio Resource Control，RRC)状态即连接非激活状态(RRC_INACTIVE状态)，这种状态有别于空闲状态(RRC_IDLE状态)和激活状态(RRC_ACTIVE状态)。
RRC_IDLE状态：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 Stotum，AS)上下文；不存在RRC连接。
RRC_CONNECTED状态：存在RRC连接，基站和UE存在UE AS上下文。网络侧知道UE的位置是具体小区级别的。移动性是网络侧控制的移动性。UE和基站之间可以传输单播数据。
RRC_INACTIVE状态：移动性为基于UE的小区选择重选，存在核心网与接入网(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，网络侧知道UE的位置是基于RAN的寻呼区域级别的。
版本(Rrevision)17中，新无线(New Radio，NR)中引入降低能力(Reduced Capability，RedCap)的设备，目前RedCap的设备主要有三个场景。
●工业无线传感器(Industrial Wireless Sensors)：和URLLC相比，这个工业无线传感器，具有相对低要求的时延和可靠性。同时这个设备的成本和功耗也比URLLC和eMBB要低。
●视频监控(Video surveillance)，主要用在智慧城市，工业工厂等视讯监控。智能城市中数据收集和处理，以便于更有效的进行城市资源的监测和控制，给城市居民提供更有效的服务。
●可穿戴设备(Wearables)，包括智能手表、手环、电子健康设备以及一些医疗监测设备等。这些设备的一个共性就是小尺寸的设备。
RRC_IDLE状态和RRC_INACTIVE状态下的测量启动
RRC_IDLE状态和RRC_INACTIVE状态下UE的邻小区测量行为受系统广播消息中的相关参数约束。例如：
对于同频测量的启动，当服务小区的小区搜索中的接收功率(Srxlev)大于用于启动同频测量的参考信号接收功率(Reference Signal Received Power，RSRP)信号的电平门限值(SIntraSearchP)，而且服务小区的小区搜索中接收的信号质量(Squal)大于用于启动同频测量的参考信号接收质量(Reference Signal Receiving Quality，RSRQ)信号质量门限值(SIntraSearchQ)时，不启动同频邻区测量，否则启动同频邻区测量。
对于同优先级或者低优先级的异频测量，当服务小区的Srxlev大于用于启动异频测量的RSRP信号的电平门限值(SnonIntraSearchP)而且服务小区的Squal大于用于启动异频测量的RSRQ信号质量门限值(SnonIntraSearchQ)时，则不启动同优先级或者低优先级的异频测量，否则启动。
对于高优先级的异频测量，总是启动对其的测量。
频点优先级的配置除了系统消息信令，还可以通过RRC释放(RRC Release)消息携带。此时，基站为UE配置专用的频点优先级，UE收到专用的频点优先级后将覆盖系统消息广播的公共的频点优先级信息。
窄带物联网(Narrow Band Internet of Things，NB-IoT)和基于长期演进(Long Term Evolution，LTE)演进的物联网技术(LTE enhanced MTO，eMTC)系统中引入的邻区测量放松
NB-IoT和eMTC是简化版、轻量版的LTE设备，针对低功耗、低成本、低速率、大连接和广覆盖的物联网应用而生。5G定义了eMBB、uRLLC和mMTC三大场景，eMBB主要针对4K/8K、虚拟现实(Virtual Reality，VR)或增强现实(Augmented Reality，AR)等大带宽应用，uRLLC主要针对远程机器人控制、自动驾驶等超高可靠超低时延应用，而NB-IoT和eMTC将演进为mMTC，主要针对低速率的大规模物联网连接。
针对低移动性的NB-IoT和eMTC终端，当服务小区RSRP变化很少时，意味着终端设备进行小区重选的需求不大，因此，可以对邻区测量进行放松，达到UE节能的目的。
针对非连接终端的RRM测量引入了两套测量放松准则：低移动性(Low-mobility)准则和终端不位于小区边缘(Not-cell-edge)准则。
1、Low-mobility准则
系统消息(系统信息块(System Information Block，SIB)3)中配置RSRP变化评估时长(TSearchDeltaP)与RSRP变化值门限(SSearchDeltaP)，就意味着该小区支持UE放松邻区测量。当且仅当满足条件时UE可进行邻区测量放松：
·时间范围(TSearchDeltaP)内满足邻区测量放松条件；
·自从上次测量不足24小时。
放松测量条件为：服务小区的参考Srxlev值相对于服务小区的当前Srxlev测量值的变化小于SSearchDeltaP。
当UE选择或重选到一个新的小区，或者(Srxlev-SrxlevRef)大于0，或者在TSearchDeltaP内放松测量条件没有满足，UE将SrxlevRef设为服务小区的当前Srxlev测量值。
其中，TSearchDeltaP取值为5分钟，或者如果配置了扩展不连续接收模式(Extended Discontinuous Reception，eDRX)且eDRX周期长于5分钟时，TSearchDeltaP取值为eDRX周期长度。
2、Not-cell-edge准则
当Srxlev大于RSRP门限(SSearchThresholdP)且Squal大于RSRQ门限(SSearchThresholdQ)(如果网络配置SSearchThresholdQ)，则UE满足not-cell-edge准则。UE可以执行邻小区测量放松。
NTN
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。
通信卫星按照轨道高度的不同分为低地球轨道(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。目前阶段主要研究的是LEO和GEO。
LEO卫星高度范围为500km～1500km，相应轨道周期约为1.5小时～2小时。用户间单跳通信的信号传播延迟一般小于20ms。最大卫星可视时间20分钟。信号传播距离短，链路损耗少，对用户终端的发射功率要求不高。
GEO卫星，轨道高度为35786km，围绕地球旋转周期为24小时。用户间单跳通信的信号传播延迟一般为250ms。
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。
目前3GPP考虑的卫星有两种，一种是透明转发(transparent payload)的卫星，一种是再生转发(regenerative payload)的卫星。透明转发的卫星只进行了信号的频率的转换、放大等过程，卫星对于信号而言是透明的。再生转发的卫星具有部分或全部基站的功能，进行了信号的频率的转换、放大，还有解调和解码，转换和/或路由，编码和调制等功能。
透明转发的卫星网络架构如图1所示，终端设备110通过下一代无线接入网(Next Generation Radio Access Network，NG-RAN)10接入与5G CN150通信，通过5G CN150连接到数据网络160。
NG-RAN10包括远程无线单元(Remote Radio Unit)20和下一代基站(Next Generation Node B，gNB)140，远程无线单元20包括卫星120和NTN网关130。卫星120与终端设备110通过服务链路或无线链路进行通信。卫星120可基于馈电链路或无线链路与NTN网关130进行通信，通过网关130连接到gNB140。
再生转发卫星网络架构如图2所示，NG-RAN10包括远程无线单元20，远程无线单元20包括卫星120和NTN网关130，且卫星120与NTN网关130之间的馈电链路基于卫星无线接口(Satellite Radio Interface，SRI)，卫星120具有部分或全部基站的功能。
在图1和图2所示的网络架构中，卫星120和NTN网关130(通常位于地面，也可称为地面网关)之间的无线链路为馈电链路。
当LEO卫星高速移动时，卫星和地面网关的连接也要发生切换，如图3所示。卫星300在T31时刻和在T32时刻的位置分别位于转换临界(transition threshold)的两侧，卫星300在T1时刻连接到网关301，卫星300在T2时刻连接到网关302。
如果网关301和网关302连接到两个地面gNB(完整的gNB或者是CU)或者一个gNB下的两个小区，那么针对该卫星覆盖的区域内所有UE，都需要在馈电链路切换后从原来的小区切换到新的小区内。如果网关301和网关302连接到同一个gNB下的同一个小区，理论上UE不需要进行切换操作。
NTN系统中，由于RSRP测量值不能准确的反应小区边缘和小区中心的差异，导致传统的基于RSRP门限的not-cell-edge准则不能准确的刻画UE在小区的位置。例如，当UE的RSRP值低于所述RSRP门限，由于RSRP测量精度的问题，UE可能处于小区中心位置，此时如果执行放松测量，则会增加UE功耗；类似的，如果UE的RSRP值高于所述RSRP门限，实际上UE可能处于小区边缘，此时按照not-cell-edge准则，UE可能没有执行测量，这样可能对终端的移动性性能造成影响，例如导致过迟的小区重选。
基于上述问题，本发明实施例提供一种无线通信方法，本发明实施例的无线通信方法可以应用于NTN系统。
示例性的，本发明实施例应用的NTN系统400，可为如图4所示，NTN系统400可以包括网络 设备410，网络设备410可以是与终端设备420(或称为通信终端、终端)通信的设备。网络设备410可以为特定的地理区域提供通信覆盖，并且可以与位于该覆盖区域内的终端设备进行通信，为覆盖区域内的终端设备提供服务。
可选地，该网络设备410为通信卫星、无人机(Unmanned Aircraft System，UAS)平台。通信卫星按照轨道高度的不同分为低地球轨道LEO通信卫星、MEO通信卫星、GEO通信卫星、HEO通信卫星等等。其中，低轨道通信卫星高度范围为500km～1500km，相应轨道周期约为1.5小时～2小时。用户间单跳通信的信号传播延迟一般小于20ms。最大通信卫星可视时间20分钟。信号传播距离短，链路损耗少，对用户终端的发射功率要求不高。地球同步轨道通信卫星，轨道高度为35786km，围绕地球旋转周期为24小时。用户间单跳通信的信号传播延迟一般为250ms。
为了保证通信卫星的覆盖以及提升整个通信卫星通信系统的系统容量，通信卫星采用多波束覆盖地面，一颗通信卫星可以形成几十甚至数百个波束来覆盖地面；一个通信卫星波束可以覆盖直径几十至上百公里的地面区域。

下面，通过不同的实例对本发明实施例提供的无线通信方法进行举例说明。
实例一、引入位置辅助信息
终端设备通过位置辅助信息判断终端设备是否满足增强的not-cell-edge准则，进而决定是否进行邻区RRM测量放松。终端设备确定是否执行测量放松的步骤，包括：

S902、终端设备获取位置辅助信息，并基于位置辅助信息和第一门限值判断是否满足第一准则。
具有GNSS定位能力的终端获取自身位置信息，并通过星历信息获取服务小区卫星的位置信息(和/或服务小区卫星覆盖参考点的位置信息)，判断所述终端是否满足增强的not-cell-edge准则，当终端设备满足以下第一条件中的一种或多种，则满足增强的not-cell-edge准则：
第一条件1、终端到服务小区卫星的距离小于距离门限值；
第一条件2、终端到服务小区卫星覆盖参考点(例如小区中心点)的距离小于对应的门限值；
第一条件3、终端到服务小区卫星的仰角大于仰角门限值；
第一条件4、终端到服务小区卫星的TA小于TA门限值；
第一条件5、终端到服务小区卫星的RTT小于RTT门限值。
S903、终端设备执行测量放松。
终端在满足以下条件时，可以执行测量放松：
条件1a、只满足基于位置辅助信息的增强的not-cell-edge准则；或
条件1b、同时满足基于位置辅助信息的增强的not-cell-edge准则和基于RSRP/RSRQ测量的not-cell-edge准则；
条件1c、满足基于位置辅助信息的增强的not-cell-edge准则和基于RSRP/RSRQ测量的not-cell-edge准则中的之一；
条件1d、当两个准则同时配置时，网络可进一步指示UE是两个准则同时满足还是任意一个满足即可判定满足not-cell-edge，进行测量放松。
如图9所示，卫星90的波束形成的服务小区的覆盖区域包括：区域91和区域92，其中，当终端设备的位置辅助信息满足增强的not-cell-edge准则，则认为终端设备位于区域91，执行测量放松，当终端设备的位置辅助信息不满足增强的not-cell-edge准则，则认为终端设备位于区域92，不执行测量放松。其中，93为服务小区的中心位置，可为服务小区卫星覆盖参考点。
本发明实施例，通过引入基于位置的增强not-cell-edge准则，可以进一步校准NTN中由于RSRP精度不准所导致的not-cell-edge判决上的误差，使得UE在不处于小区边缘时才进行放松测量，降低功耗。

终端设备根据第二门限值判断是否满足时间相关的准则，当终端设备满足以下第一条件中的一种或多种，则满足时间相关的准则：
第二条件一、当前时刻早于绝对时刻门限值T1。
例如，绝对时刻门限值对应于feeder link switch服务小区即将消失T0前的一个时刻，T1之后服务小区即将消失，UE应该正常启动邻区测量以尽快发现目标小区。
第二条件二、当前时刻位于绝对时刻区间[T2，T3]。
例如，对于quasi-earth-fixed cell场景，当前卫星服务该区域的时刻区间为[T4，T5]，即当前小区的可用时间为[T4，T5]，网络配置的时刻区间[T2，T3]位于[T4，T5]内，那么在[T2，T3]内可以认为UE仍处于该小区的服务范围，[T2，T4]以及[T3，T5]属于小区即将要离开的时刻，UE应该正常启动邻区测量以尽快发现目标小区。
S1003、终端设备执行测量放松。
