Description

一种用户设备、基站中的窄带蜂窝通信的方法和装置 技术领域
本发明涉及无线通信***中的传输方案，特别是涉及支持无线中继传输(Transmission)的方法和装置。
背景技术
第三代合作伙伴项目(3GPP-3rd Generation Partner Project)R(Release，发布)9中提出了层3(Layer-3)的中继(Relay)基站的方案。中继基站对于UE(User Equipment，用户设备)而言具备普通基站的功能，能够独立的调度数据及发送下行HARQ-ACK(Hybrid Automatic Repeat reQuest，混合自动重传请求)。
传统的3GPP***中，数据传输发生在基站和UE之间。在3GPP R12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之间的数据传输。在3GPP R13中，eD2D(Enhancements to LTE Device to Device)被立项，其主要特点是引入UE中继(Relay)功能。在eD2D中，中继用户设备(Relay UE)中继远端用户设备(Remote UE)和基站之间的数据交换。
在3GPP RAN(Radio Access Network，无线接入网)#69次全会上，NB-IOT(NarrowBand Internet of Things，窄带物联网)被立项。进一步的，在3GPP RAN#71次全会上(RP-160655)，针对IoT和可穿戴设备的FeD2D(Further Enhancements to LTE Device to Device，LTE D2D的进一步增强)被立项。FeD2D中，D2D通信可能通过类似NB-IoT的空中接口实现。
FeD2D的一个典型的应用场景就是在一个智能终端的周围存在多个可穿戴设备。智能终端中继可穿戴设备到基站的数据交换，即智能终端和可穿戴设备分别是Relay UE和Remote UE。
发明内容
Release 12D2D传输主要针对公共安全(Public Safety)的场景， 因此在设计数据传输时，均采用重复传输的方式。终端设备和终端设备之间没有链路自适应(Link Adaptation)，也没有CSI(Channel State Information，信道状态信息)反馈。对于FeD2D，考虑到频谱效率和传输可靠性的兼顾，终端设备和终端设备之间的CSI，即Relay UE和Remote UE的CSI，需要被基站获得，以进行链路自适应以及调制编码方式的适配。
一种直观的解决方案是重用3GPP R9中的中继基站的方案，即Relay UE具备中继基站的功能，且所有Remote UE的调度通过Relay UE实现。发明人通过研究发现，上述直观的方法对于智能终端的功耗和复杂度均提出了很高要求，因此较难实现。
本发明针对上述问题提供了解决方案。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UE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。又例如，本申请的D2D发送UE(即在D2D链路上发送无线信号)中的实施例和实施例中的特征可以应用到D2D接收UE(即在D2D链路上接收所述无线信号)中，反之亦然。进一步的，虽然本发明的初衷是针对FeD2D(即D2D传输是基于窄带的)，本发明的方案也适用于宽带D2D中继(即D2D传输是基于宽带的)。
本发明公开了一种被用于中继通信的UE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.发送第二无线信号和第三无线信号。
其中，第一无线信号被用于确定第二无线信号，所述第二无线信号包括{第一信息，第一数据}中的一种。所述第一无线信号的发送者是第一节点，所述第二无线信号的接收者包括第二节点。所述第三无线信号被用于确定以下至少之一：
-.所述第二无线信号中包括第一信息还是第一数据
-.所述第一节点是否是所述UE的服务小区
-.所述第一节点的标识。
所述第一信息在物理层生成，所述第一数据在高层生成。
在基于D2D的中继传输中，中继UE而不是基站知道旁行链路 (Sidelink)的链路质量以及传输状态。因此，利用第三无线信号，所述UE能自行确定所述第二无线信号所包括的内容。
传统的D2D以及eD2D中，UE无法自行决定上行信号所包括的内容。因此，上述方法能更高效的利用上行空口资源，提高传输效率。
作为一个实施例，所述第一节点和所述第二节点分别是Remote UE和基站。上述实施例中，Relay UE通过第一信号获取旁行链路(Sidelink)的信道质量，并通过第二无线信号发送给基站，以帮助基站进行Remote UE到Relay UE传输的链路自适应和调制编码方式的适配。
作为一个实施例，所述第一无线信号所占用的带宽不超过180kHz。

上述“所述第三无线信号被用于确定所述第二无线信号中包括第一信息还是第一数据”的设计特质在于，当基站为Remote UE到Relay UE之间的无线链路的信道质量相关信息分配上行资源后，因为Remote UE到Relay UE之间的无线链路因Remote UE相对Relay UE静态的特性，所述信道质量相关信息变化不快，频繁更新所述信道质量相关信息没有意义。Relay UE就可以通过所述第三无线信号的指示，在基站分配的资源上传输Relay UE自己的上行数据，以提高频带利用率。
上述“所述第三无线信号被用于确定所述第一节点是否是所述UE的服务小区”的设计特质在于，若Relay UE下不存在Remote UE，则基站为Remote UE到Relay UE之间的无线链路的信道质量相关信息分配的上行资源，仍然可以用做Relay UE上行数据的传输，以提高频带利用率。
