具体实施方式
下面将结合本申请实施例中的附图,对本申请实施例中的技术方案进行描述,显然,所描述的实 施例是本申请一部分实施例,而不是全部的实施例。针对本申请中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都属于本申请保护的范围。
本申请实施例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、先进的长期演进(Advanced long term evolution,LTE-A)系统、新无线(New Radio,NR)系统、NR系统的演进系统、免授权频谱上的LTE(LTE-based access to unlicensed spectrum,LTE-U)系统、免授权频谱上的NR(NR-based access to unlicensed spectrum,NR-U)系统、通用移动通信系统(Universal Mobile Telecommunication System,UMTS)、无线局域网(Wireless Local Area Networks,WLAN)、无线保真(Wireless Fidelity,WiFi)、下一代通信系统或其他通信系统等。
通常来说,传统的通信系统支持的连接数有限,也易于实现,然而,随着通信技术的发展,移动通信系统将不仅支持传统的通信,还将支持例如,设备到设备(Device to Device,D2D)通信,机器到机器(Machine to Machine,M2M)通信,机器类型通信(Machine Type Communication,MTC),以及车辆间(Vehicle to Vehicle,V2V)通信等,本申请实施例也可以应用于这些通信系统。
可选地,本申请实施例中的通信系统可以应用于载波聚合(Carrier Aggregation,CA)场景,也可以应用于双连接(Dual Connectivity,DC)场景,还可以应用于独立(Standalone,SA)布网场景。

应理解,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。
本申请实施例结合终端设备和网络设备描述了各个实施例,其中:终端设备也可以称为用户设备(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等。终端设备可以是WLAN中的站点(STAION,ST),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)设备、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、可穿戴设备以及下一代通信系统,例如,NR网络中的终端设备或者未来演进的公共陆地移动网络(Public Land Mobile Network,PLMN)网络中的终端设备等。
作为示例而非限定,在本申请实施例中,该终端设备还可以是可穿戴设备。可穿戴设备也可以称为穿戴式智能设备,是应用穿戴式技术对日常穿戴进行智能化设计、开发出可以穿戴的设备的总称,如眼镜、手套、手表、服饰及鞋等。可穿戴设备即直接穿在身上,或是整合到用户的衣服或配件的一种便携式设备。可穿戴设备不仅仅是一种硬件设备,更是通过软件支持以及数据交互、云端交互来实现强大的功能。广义穿戴式智能设备包括功能全、尺寸大、可不依赖智能手机实现完整或者部分的功能,例如:智能手表或智能眼镜等,以及只专注于某一类应用功能,需要和其它设备如智能手机配合使用,如各类进行体征监测的智能手环、智能首饰等。
网络设备可以是用于与移动设备通信的设备,网络设备可以是WLAN中的接入点(Access Point,AP),GSM或CDMA中的基站(Base Transceiver Station,BTS),也可以是WCDMA中的基站(NodeB,NB),还可以是LTE中的演进型基站(Evolutional Node B,eNB或eNodeB),或者中继站或接入 点,或者车载设备、可穿戴设备以及NR网络中的网络设备或者基站(gNB)或者未来演进的PLMN网络中的网络设备等。
在本申请实施例中,网络设备为小区提供服务,终端设备通过该小区使用的传输资源(例如,频域资源,或者说,频谱资源)与网络设备进行通信,该小区可以是网络设备(例如基站)对应的小区,小区可以属于宏基站,也可以属于小小区(Small cell)对应的基站,这里的小小区可以包括:城市小区(Metro cell)、微小区(Micro cell)、微微小区(Pico cell)、毫微微小区(Femto cell)等,这些小小区具有覆盖范围小、发射功率低的特点,适用于提供高速率的数据传输服务。
在初始小区选择中,终端设备根据自身能力通过扫描NR频带内的所有载波来找到一个合适的小区,在每个载波频率上,终端设备只需要寻找信号最强的小区,一旦找到一个合适的小区,则选择这个小区。
在带有储存信息的小区选择中,需要事先保存好的载波频率信息,以及小区参数相关的信息(可选),这些信息是从先前接收到的测量控制信息得来,或从先前检测过的小区得来。一旦终端设备找到一个合适的小区,则应该选择这个小区。如果没找到合适的小区,则应该启动初始小区选择。
在小区重选中,LTE小区重选(cell reselection)指终端设备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(Srxlev)且满足一定重选判决准则时,终端将接入该小区驻留。
终端设备成功驻留后,将持续进行本小区测量。无线资源控制(Radio Resource Control,RRC)层根据参考信号接收功率(Reference Signal Receiving Power,RSRP)测量结果计算S准则,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。
在空闲态(IDLE)和去激活态(inactive)的小区重选R准则以及候选小区选择中,同频和同优先级异频小区重选时遵循以下准则:
Rs=Qmeas,s+Qhyst-Qoffsettemp
Rn=Qmeas,n-Qoffset-Qoffsettemp
其中,Qmeas,s是服务小区的RSRP测量值,Qmeas,n是邻小区的RSRP测量,Qoffset是一个偏移值,Qoffsettemp是一个临时偏移值,Qhyst是一个迟滞值。
如果网络设备没配置优选小区列表(rangeToBestCell),则终端设备针对服务小区和邻小区的Rs和Rn值进行排序,在服务小区和众多的邻小区中间选择Rs/Rn排序最高的小区进行小区重选。
如果网络配置了优选小区列表(rangeToBestCell),则终端设备在由参数rangeToBestCell定义的最高排序的多个小区中选择好的波束(beam)数最多的那个小区进行重选,其中好的beam由一个门限值来定义。如果这样的小区有很多,则终端设备重选到排序最高的那个小区。
无人驾驶航空器(Unmanned Aerial Vehicle,UAV)简称为无人机,其全球市场在过去十年中大幅增长,现在已经成为商业、政府和消费应用的重要工具。无人机能够支持诸多领域的解决方案,可以广泛应用于建筑、石油、天然气、能源、公用事业和农业等领域。当前,无人机技术正在朝军民融合的方向高速发展,无人机产业已经是国际航空航天最具活力的新兴市场,成了各国经济增长的亮点。
对于无人机终端设备,其需要频繁执行小区重选并且读取邻小区的系统消息且判断该小区是否为无人机小区。因此,无人机终端设备会执行一些不必要的测量和小区选择或者小区重选,影响了无人机终端设备的通信性能。
基于上述技术问题,本申请实施例提供一种无线通信方法,通过为无人机终端配置特定的小区列表,使得无人机终端在进行小区重选以及测量时候可以避免对于非无人机小区不必要的测量,增加了小区重选/接入过程的可靠性。
