Description

一种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系统中的传输方案,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系统中,数据传输发生在基站和UE之间。在3GPP R12中,D2D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。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。NB-IOT支持3种不同的运行模式(RP-151621):
1.独立(Stand-alone)运行,在GERAN系统使用的频谱上部署。
2.保护带运行,在LTE(Long Term Evolution,长期演进)载波的保护带中的未使用的资源块上部署
3.带内运行,在LTE载波上的资源块上部署
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
对于FeD2D,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。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。另外一种直观的解决方案是尽可能重用eD2D的方案,即Relay UE和Remote UE均通过广播的方式发送信令和数据。发明人通过研究发现,由于eD2D以PSCCH(Physical Sidelink Control Channel,物理旁行控制信道)间隔(Period)为基本调度单位并且不支持HARQ,重用eD2D的方案可能增大Remote UE的功率损耗。
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(User Equipment,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。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.接收第一信令。
-步骤B.在第一子帧组中接收第一无线信号。
-步骤C.在第二子帧组中发送第二无线信号。

作为一个实施例,所述UE根据所述第一信令确定所述第一无线信号所占用的时域位置以及所述第二无线信号所占用的时域位置。本实施例的优点是节省了信令的开销,即所述UE不需要通过两个信令分别获得所述第一无线信号所占用的时域位置以及所述第二无线信号所占用的时域位置。
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。上述方法和现有D2D/eD2D技术的区别在于,第一信令能够同时被用于确定下行时域资源和PC5(D2D链路)的时域资源。

上述实施例中,所述UE将和所述第一节点发送的上行数据相关联的HARQ-ACK(通过所述第二无线信号)中继给所述第二节点,由于所述HARQ-ACK信息所需上行资源较小且有可能重用先有上行HARQ-ACK方案,所述HARQ-ACK信息能够先于所述第一无线信号被中继。上述实施例能 让所述第二节点尽可能早的确定所述第一无线信号被正确译码,降低HARQ延时。
