Description

一种UE、基站中在非授权频谱上的通信方法和设备 技术领域
本发明涉及无线通信系统中利用非授权频谱通信的方案，特别是涉及基于长期演进(LTE-Long Term Evolution)的针对非授权频谱(Unlicensed Spectrum)的通信方法和装置。
背景技术
传统的第三代合作伙伴项目(3GPP–3rd Generation Partner Project)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，即非授权频谱综合的研究(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载波聚合(CA-Carrier Aggregation)的概念，即部署在授权频谱上的服务小区作为主载波(PCC-Primary Component Carrier)，部署在非授权频谱上的服务小区作为辅载波(SCC-Secondary Component Carrier)。
传统的载波聚合中，用户设备(UE-User Equipment)最多能够同时被配置5个下行载波，并且最多在5个下行载波上同时接收物理下行共享信道(PDSCH-Physical Downlink Shared Channel)并在PCC的物理上行控制信道(PUCCH-Physical Uplink Control Channel)上反馈针对所述下行载波上的PDSCH的混合自动重传请求(HARQ-Hybrid Automatic Repeat Request)应答(HARQ_ACK)。反馈HARQ_ACK可能使用PUCCH格式1b或者PUCCH格式3，其中格式1b结合了信道选择(Channel Selection)技术适用于2个载波以及不超过4个HARQ_ACK比特的场景，而格式3能够支持最多20个HARQ_ACK比特。
对于非授权频谱，考虑到其干扰水平的不可控制/预测，UE可能被配置更多的下行载波，同时采用动态频谱选择(DFS-Dynamical Frequency Selection)的方式(在给定子帧)从配置的下行载波中选 择出部分下行载波用于PDSCH的发送。进一步的，考虑到非授权频谱的带宽较大，例如仅在5GHz载频附近就有约500MHz可用的非授权频谱，UE被配置的载波数量可能较大(远大于5)。传统的PUCCH格式3也无法支持对所有被配置的载波反馈HARQ_ACK。此外，采用了DFS以后可能会导致在同一个物理载波上的频繁不连续传输，进而导致HARQ重传的间隔增加，增加了传输延时。
针对上述问题，本发明公开了一种在非授权频谱上的通信方法和装置。
发明内容
本发明公开了一种UE中在非授权频谱上的通信方法，其中,包括如下步骤：
-步骤A.接收高层信令获得S和V，所述S是L组配置信息，所述V是N组逻辑信息，所述配置信息包括载波索引和工作频带，所述逻辑信息包括以下至少之一：
-载波逻辑索引
-天线信息，所述天线信息包括传输模式
-跨载波信息，所述跨载波信息包括服务小区索引
-步骤B.接收第一下行控制指示(DCI-Downlink Control Information)，所述第一DCI包括虚拟索引和调度信息
-步骤C.在给定子帧从第一配置信息中的工作频带上根据第一DCI中的调度信息接收第一PDSCH
其中，第一DCI遵守第一逻辑信息的配置，第一逻辑信息是所述V中载波逻辑索引等于第一DCI中的虚拟索引的一组所述逻辑信息。所述S中的工作频带都属于非授权频谱，所述L是正整数，所述N是不大于所述L的正整数，第一配置信息是以下之一：
-选项一.所述S中工作频带包括第一DCI的传输带宽的一组所述配置信息
-选项二.所述S中载波索引等于第一DCI中的调度信息中的物理索引的一组所述配置信息。
作为一个实施例，所述第一DCI遵守第一逻辑信息的配置包括以下 至少之一：
-第一DCI的传输载波由第一逻辑信息中的跨载波信息指示
-第一DCI可选的格式由第一逻辑信息中的传输模式指示
-第一PDSCH可选的解调参考信号端口由第一逻辑信息中的传输模式指示。
上述方面的本质是，通过使用逻辑信息标识逻辑载波，所述逻辑载波的识别通过DCI中携带的虚拟索引是否等于对应的逻辑信息中的载波逻辑索引确定。携带了相同虚拟索引的DCI所调度的PDSCH属于同一个逻辑载波，共享对应逻辑信息的配置，例如传输模式跨载波信息等等。
作为一个实施例，所述V中的配置信息的激活/失活状态均被媒体接入控制(MAC-Media Access Control)信令设置为激活状态。
作为一个实施例，所述工作频带包括载波中心频率和载波带宽。作为又一个实施例，所述工作频带包括下载频和上载频。
作为一个实施例，所述载波逻辑索引是小于8的正整数-使用3个比特表示所述载波逻辑索引且0配置给主小区。第一DCI中的虚拟索引替代了传统DCI中的载波指示域(CIF-Carrier Indicator Field)比特。
作为一个实施例，所述天线信息包括LTE中的AntennaInfo的全部或者部分信息。
作为一个实施例，跨载波信息包括LTE中的crossCarrierSchedulingConfig的全部或者部分信息。
作为一个实施例，所述高层信令是无线资源控制(RRC-Radio Resource Control)信令。
作为一个实施例，第一DCI中的调度信息中是否包含物理索引是由高层信令配置的，如果不包含物理索引则第一DCI不能进行跨载波调度-即第一DCI只能调度本载波的PDSCH。
具体的，根据本发明的一个方面，所述逻辑信息包括所述跨载波信息，第一DCI在第一逻辑信息中的所述跨载波信息标识的服务小区的下行资源上传输，第一配置信息是所述选项二。
所述服务小区部属于授权频谱，所述下行资源是FDD的下行载波或者是TDD的下行子帧。
具体的，根据本发明的一个方面，所述N为1。
具体的，根据本发明的一个方面，所述配置信息还包括以下至少之一
-小区物理标识，所述小区物理标识是0到503的正整数
-参考信号配置信息
-PDSCH配置信息。
作为一个实施例，所述小区物理标识用于相应配置信息中工作带宽上接收的PDSCH的解扰码操作。
作为一个实施例，所述参考信号配置信息包括LTE中的csi-RS-Config-r10全部或者部分信息。作为又一个实施例，所述PDSCH配置信息包括发送功率相关参数，例如每资源粒子能量(EPRE-Energy Per Resource Element)。
具体的，根据本发明的一个方面，所述V共享相同的传输模式。
作为一个实施例，所述N组逻辑信息的所述天线信息是通过一个公共信息粒子(IE-Information Element)配置的或者是预确定的。
具体的，根据本发明的一个方面，还包括如下步骤：
-步骤D.如果第一PDSCH是重传，对第一PDSCH执行HARQ合并
其中，和第一PDSCH进行HARQ合并的PDSCH其调度DCI中的虚拟索引和第一DCI中的虚拟索引相等。
上述方面的本质是，下行HARQ合并是在由所述逻辑信息标识的逻辑载波中执行。这样就减少了DFS引入导致的HARQ延时。
具体的，根据本发明的一个方面，所述HARQ合并重用LTE合并方案，所述LTE合并方案假设所述和第一PDSCH进行HARQ合并的PDSCH同第一PDSCH处于相同物理频带。
根据上述方面，所述LTE合并方案包括对第一DCI中的调度信息中的HARQ信息的解读(即合并PDSCH的选择)，HARQ合并译码方案等操作。作为一个实施例，所述HARQ信息包括HARQ进程号，冗余版本(RV-Redundancy Version)，新数据指示(NDI-New Data Indicator)。具体的HARQ信息的解读参考3GPP标准TS36.321。
具体的，根据本发明的一个方面，还包括如下步骤：
-步骤E.发送HARQ_ACK指示所述给定子帧中的PDSCH的接收情况
其中，所述HARQ_ACK所指示的传输块的数量由至少以下之一确定：
-所述V中的传输模式
-所述UE在授权频谱上被配置的所有服务小区的传输模式。
上述方面的本质是，根据所述V中的传输模式(而不是根据所述S的信息)预留针对非授权频谱上的PDSCH的HARQ_ACK比特，这样就减少了预留的HARQ_ACK比特数。所述HARQ_ACK可能只是三种状态，即ACK/NACK/DTX。
具体的，根据本发明的上述方面，按照LTE上行ACK方案确定传输所述HARQ_ACK的PUCCH的格式和比特数以及物理资源映射，所述LTE上行ACK方案基于所述UE被配置了1个主小区和X-1个辅小区。所述X-1个辅小区包括X-1-N个部署于授权频谱上的辅小区和所述V标识的N个辅小区。
作为上述方面的一个实施例,如果所述HARQ_ACK是采用PUCCH格式3，所述HARQ_ACK由X个比特组级联而成，所述X是所述UE在授权频谱上被配置的服务小区数加上所述N，每个比特组指示以下之一：
-一个在授权频谱上被配置的服务小区上的PDSCH的接收情况
-一个在非授权频谱上被配置的逻辑载波上的PDSCH的接收情况，所述X个比特组中的第x个比特组指示了第一PDSCH所属的逻辑载波的接收情况，所述x是第一DCI中的虚拟索引在索引集合中的位置索引，所述索引集合是所述UE在授权频谱上被配置的服务小区的小区索引和所述V中的载波逻辑索引按升序排列组成的集合。对于FDD，第x个比特组的比特数是第一逻辑信息中的传输模式所能支持的最大传输块数-所述传输模式为{1，2，5，6，7}中的一种时，第x个比特组包括1个比特，所述传输模式为{3，4，8，9，10}中的一种时，第x个比特组包括2个比特。对于TDD，第x个比特组可能还指示除了所述给定子帧之外的其他子帧的PDSCH的接收情况，只要所述其他子帧的PDSCH和第一PDSCH属于同一个逻辑载波-即所述其他子帧的PDSCH的调度DCI中的虚拟索引和第一DCI中的虚拟索引相等。所述其他子帧参考3GPP标准TS36.211中的表格10.1.3.1-1。
作为所述LTE上行ACK方案一个实施例，如果所述X大于2且所述HARQ_ACK在频分双工(FDD-Frequency Division Duplex)载波上传 输，则HARQ_ACK在格式3的PUCCH上传输。如果所述HARQ_ACK在TDD载波上传输，所述HARQ_ACK是采用PUCCH格式1b还是格式3是由高层信令配置的。
作为所述LTE上行ACK方案的又一个实施例，如果所述HARQ_ACK指示3个数据块且传输PUCCH的格式是结合了信道选择的格式1b，所述HARQ_ACK是在

标识的PUCCH资源上发送2个比特b(0)b(1)，其中
