Description

一种被用于无线通信的用户设备、基站中的方法和装置 技术领域
本发明涉及无线通信中的传输方法和装置，尤其涉及被用于空中终端与地面设备进行通信的方法和装置。
背景技术
在3GPP(3rd Generation Partner Project，第三代合作伙伴项目)Release 12中，D2D(Device to Device，设备间)通信被立项并加以讨论，D2D的本质特点是允许UE(User Equipment，用户设备)之间的数据传输。传统的D2D通信中，考虑到D2D传输的鲁棒性以及对Cellular(蜂窝)通信的干扰，当D2D UE位于蜂窝网覆盖下(In Coverage)时，所述D2D UE在Sidelink(副链路)上以及蜂窝链路上的传输，均受到所述D2D用户设备对应的服务小区(Serving Cell)的控制。
在3GPP关于5G的讨论中，关于增强的支持空中通信(Enhanced Support for Aerial Vehicles)的SI(Study Item，研究项目)已被立项，并在3GPP中被讨论。空中通信的一个特点就是一个空中终端设备的传输会被多个基站检测到，相应的面向空中终端与地面终端间的传输方法需要被重新考虑。
发明内容
空中通信一个重要的特点就是，位于空中的终端在到达一定高度之后，与地面终端和基站之间往往都是LOS(Line of Sight，可视)径。因为LOS径的原因，当目标小区中的空中终端与所述空中终端对应的地面终端或者所述目标小区对应的基站进行通信时，所述目标小区附近的相邻小区的地面终端和相邻小区对应的基站均能收到来自所述空中终端的信号，进而带来较大的小区间干扰。
现有LTE(Long Term Evolution，长期演进)D2D应用场景中，无论接收对象是基站，还是接收对象是D2D发送端的对端用户设备，D2D发送端的传输均基于发送端的服务小区的控制。上述方法是为了确保 D2D发送端的传输不会对蜂窝链路造成干扰。空中通信中的空中终端和地面终端之间的通信将很大程度上继承LTE D2D通信的传输协议。同时，Release 14基于D2D的V2X(Vehicle to X，车对未知终端)演进的讨论中，GNSS(Global Navigation Satellite System，全球卫星导航系统)的同步也被引入到D2D对之间的同步应用中。针对空中终端的发送可以被地面的多个小区对应的基站接收到的特点，以及空中终端更易实现与GNSS同步的特质，新的基于空中终端的传输方式需要被考虑。
针对上述问题，本发明提供了解决方案。需要说明的是，在不冲突的情况下，本申请的实施例和实施例中的特征可以任意相互组合。例如，本申请的用户设备中的实施例和实施例中的特征可以应用到基站中，反之亦然。
本发明公开了一种被用于无线通信的用户设备中的方法，其中，包括如下步骤：
-步骤A.接收第一无线信号；
-步骤B.接收第二无线信号；
-步骤C.发送第三无线信号。
其中，所述第一无线信号被用于确定第一特征序列，所述第二无线信号的接收定时被用于确定所述第三无线信号的发送定时。所述第一特征序列被用于生成所述第三无线信号。所述第一无线信号和所述第二无线信号分别和第一同步序列和第二同步序列关联，所述第一同步序列和所述第二同步序列不同。
作为一个实施例，上述方法的一个特质在于：所述第一无线信号的发送者和所述第二无线信号的发送者是不同的，所述用户设备从两个发送者分别获得定时和同步序列的生成指示。
作为一个实施例，上述方法的好处在于：由于与地面基站或者终端之间是LOS径，空中终端同时与两个地面设备进行通信，其中一个所述地面设备被用于同步，另一个地面设备被用于传输控制信息。上述方法使所述空中终端与地面终端的传输更加灵活，而不需要将所有空中终端的信息均通过服务小区传输，进而避免了空中终端频繁切换的问题。
作为一个实施例，上述方法的另一个特质在于：现有V2X设计，当 所述D2D设备的同步源是GNSS，所述D2D设备用于生成同步序列的特征序列的SLSSID(Sidelink Synchronization Sequence Identifier，副链路同步序列标识)是固定的。上述方法中，当所述第三无线信号被用于所述空中设备的对端设备进行同步且所述第二无线信号是来自GNSS的信号时，所述第一特征序列是可配置的。上述方法增加了系统的灵活性，进而更易区分来自不同空中设备的同步信号。
作为一个实施例，上述方法的再一个特质在于：当所述第三无线信号用于{发送功率控制，触发所述用户设备发送参考信号，触发所述用户设备发送信道状态信息}中的至少之一时，所述第三无线信号的发送触发基于所述第一无线信号的发送者和所述第二无线信号的发送者之外的小区，从而实现当空中终端移动出服务小区时，空中终端的覆盖范围中的任何一个小区均支持向空中终端发送非调度类的控制信令，进一步改善空中终端的移动性和增加系统的灵活性。其中，在所述覆盖范围中的地面设备均能成功检测来自所述空中终端的发送信号。
