Description
本发明涉及无线通信系统中利用非授权频谱通信的方案,特别是涉及基于LTE(Long Term Evolution,长期演进)的针对非授权频谱(Unlicensed Spectrum)的通信方法和装置。
3GPP(3rd Generation Partner Project,第三代合作伙伴项目)定义了LTE系统中的TDD(Time Division Duplex,时分双工)帧结构,如表1所示,其中D表示下行子帧,U表示上行子帧,S为特殊子帧:
表1:TDD LTE帧结构
3GPP R(Release,版本)12中引入了eIMTA(enhanced Interference Management Traffic Adaptation,增强的干扰管理业务自适应)技术,即对于TDD帧结构,能够通过动态信令调整TDD帧结构,可能的TDD帧结构包括LTE中定义的#0~#6共7种TDD帧结构。
传统的3GPP LTE系统中,数据传输只能发生在授权频谱上,然而随着业务量的急剧增大,尤其在一些城市地区,授权频谱可能难以满足
业务量的需求。3GPP RAN的62次全会讨论了一个新的研究课题,即非授权频谱的研究(RP-132085),主要目的是研究利用在非授权频谱上的LTE的非独立(Non-standalone)部署,所谓非独立是指在非授权频谱上的通信要和授权频谱上的服务小区相关联。一个直观的方法是尽可能重用现有系统中的CA(Carrier Aggregation,载波聚合)的概念,即部署在授权频谱上的服务小区作为Pcell(Primary Cell,主小区),部署在非授权频谱上的服务小区作为Scell(Secondary Cell,辅小区)。所述CA包括传统的TDD CA,FDD(Frequency Division Duplex,频分双工)CA,以及3GPP R12引入的FDD-TDD CA。
部署在非授权频谱上的载波可能用于传输下行及上行数据。为了更灵活的适应上下行不对称的数据突发,非授权频谱上可能采用更灵活的(全新的)上下行子帧配置。而如何对非授权频谱进行调度是一个需要解决的问题。
针对上述问题,本发明公开了一种UE、基站中在非授权频带上的通信方法和设备。
发明内容
本发明公开了一种UE(User Equipment,用户设备)中在非授权频带上的通信方法,包括如下步骤:
-步骤A.接收高层信令。所述高层信令指示第一载波能被在第二服务小区上传输的控制信令调度。所述高层信令指示第一载波能被在第一载波上传输的控制信令调度,或者第一载波缺省能被在第一载波上传输的控制信令调度;
其中,第一载波部署于非授权频谱,第二服务小区部署于授权频谱。
上述方面的本质是,对UE而言,非授权频谱同时支持自调度和跨载波调度。作为一个实施例,所述高层信令是RRC(Radio Resource Control,无线资源控制)层信令。作为一个实施例,所述服务小区包括一个部署于TDD授权频谱的载波。作为一个实施例,所述服务小区包括一个部署于FDD授权频谱的下行载波和一个部署于FDD授权频谱的上行载波。作为一个实施例,所述高层信令显式指示用于调度第一载波的控制信令能够在第一载波和第二服务小区上传输。作为一个实施例,所

-步骤C.在第二服务小区的第二子帧接收第二控制信令;根据第二控制信令的调度在第一载波上接收第二物理层数据并发送第二ACK/NACK,或者发送第二物理层数据并接收第二ACK/NACK;
其中,第一子帧和第二子帧在时域上是不同的两个子帧,第一ACK/NACK指示第一物理层数据是否正确接收,第二ACK/NACK指示第二物理层数据是否正确接收。
作为一个实施例,所述控制信令是下行调度DCI(Downlink Control Information,下行控制信息),其携带的调度信息是DCI格式{1,1A,1B,1C,1D,2,2A,2B,2C,2D}的调度信息中的一种。作为一个实施例,所述控制信令是上行调度DCI,其携带的调度信息是是DCI格式{0,4}的调度信息中的一种。

上述方面的本质是,非授权频谱上的HARQ(Hybrid Automatic Repeat Request,混合自动重传请求)时序不需要考虑和传统UE的兼容性地问题,因此可以使用10毫秒的RTT(Round Trip Time,回环时间)。
具体的,根据本发明的一个方面,第二子帧集合包括第二服务小区中所有能传输用于调度第一载波的控制信令的子帧。
