本申请实施例中,所述"协议"可以指通信领域的标准协议,例如可以包括LTE协议、NR协议以及应用于未来的通信系统中的相关协议,本申请对此不做限定。
为便于理解本申请实施例的技术方案,以下通过具体实施例详述本申请的技术方案。以下相关技术作为可选方案与本申请实施例的技术方案可以进行任意结合,其均属于本申请实施例的保护范围。本申请实施例包括以下内容中的至少部分内容。
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。
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。其中,NTN网络可以包括一个或多个网关(Gateway),用于卫星和终端之间的通信。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。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。
在上行传输中,为了保证上行传输的正交性,避免小区内(intra-cell)干扰,网络要求来自同一时刻但不同频域资源的不同UE的信号到达网络的时间基本上是对齐的。为了保证网络侧的时间同步,引入了上行定时提前(Time Advance,TA)的机制。
网络侧的上行时钟和下行时钟是相同的,而UE侧的上行时钟和下行时钟之间有偏移,并且不同UE有各自不同的上行定时提前量。网络通过适当地控制每个UE的偏移,可以控制来自不同UE的上行信号到达网络的时间。对于离网络较远的UE,由于有较大的传输时延,就要比离网络较近的UE提前发送上行数据。
在NTN场景中,由于终端和网络之间的信号传输时延较大,为了便于终端完成初始随机接入,网络可以给终端设备配置公共TA。可选地,该公共TA可以是基于近地点与基站之间的信号传输时延确定的。
为了满足高速率的需求,NR系统也支持CA技术。CA技术是通过联合调度和使用多个成员载波(Component Carrier,CC)上的资源,使得NR系统可以支持更大的带宽,从而能够实现更高的系统峰值速率。根据所聚合载波的在频谱上的连续性可以分为,连 续性载波聚合和非连续性载波聚合;根据聚合的载波所在的带宽(band)是否相同,分为带宽内(Intra-band)载波聚合和带宽外(inter-band)载波聚合。
在NR早期部署时,完整的NR覆盖很难获取,所以典型的网络覆盖是广域的LTE覆盖和NR的孤岛覆盖模式。而且大量的LTE部署在6GHz以下,可用于5G的6GHz以下频谱很少。所以NR必须研究6GHz以上的频谱应用,而高频段覆盖有限、信号衰落快。同时为了保护移动运营商前期在LTE投资,提出了LTE和NR之间tight interworking的工作模式,即DC技术。
DC可以有多种工作模式,例如EN-DC(LTE-NR Dual Connectivity),NE-DC,5GC-EN-DC,NR DC等。对于EN-DC,接入网连接的核心网是EPC,而其他DC模式,接入网连接的核心网是5GC。
在引入NTN之后,可以考虑TN和NTN之间的CA,以及NTN和NTN之间的CA,TN和NTN之间、NTN和NTN之间的DC,而对于不同类型的小区,终端设备的接入方案会有不同,因此,终端设备如何区分小区的类型以实现有效的随机接入是一项急需解决的问题。
