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)的调度方法和装置。
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)最多能够监测调度5个载波上的动态控制指示(DCI-Dynamic Control Indicator)及在5个载波上接收数据。而对于非授权频谱,UE可能需要检测针对更多载波的DCI,主要原因如下:
-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,以LTE最大系统带宽20MHz计算,UE仅在5GHz载频附近可能要同时监测25个载波
-非授权频谱上的干扰不可控制/预测导致UE可能需要频繁在候选频谱上选择干扰较小的载波
-下一代移动通信要求UE能够达到更高的峰值速率
UE检测过多的DCI可能带来如下挑战:
-更多的盲检测(BD-Blind Decoding)次数带来的复杂度提升, 对于一个载波,UE可能要执行32~44次BD操作。
-更多的冗余度带来的资源浪费
针对上述问题,本发明公开了一种非授权频谱上的调度方法和装置。

其中,第一服务小区部署在授权频谱上,所述N是正整数,所述M是正整数,所述K是不大于所述N的正整数,所述L是正整数,所述K个载波索引或者所述K个标志位对应的载波索引是所述N组配置信息中包含的N组载波索引的子集。
本发明公开了一种基站中非授权频谱上的调度方法,其中,包括如下步骤:
步骤A.在第一服务小区发送第一高层信令指示N组配置信息,1组所述配置信息包括载波索引以及工作频带;
步骤B.发送第一DCI指示K个物理载波的载波索引和针对所述K个物理载波的调度信息;第一DCI中包括第一信息,第一信息是以下之一:
选项1:K个载波索引,所述载波索引包括L个比特;
选项2:M个标志位,所述标志位包括1个比特,其中K个标志位设置为状态1;

其中,第一服务小区部署在授权频谱上,所述N是正整数,所述M是正整数,所述K是不大于所述N的正整数,所述L是正整数,所述K个载波索引或者所述K个标志位对应的载波索引是所述N组配置信息中包含的N组载波索引的子集。所述K个物理载波的载波索引和所述K个载波索引或这所述K个标志位是一一对应的。所述标志位设置为状态1表示其对应的物理载波被调度,设置为状态0表示其对应的物理载波未被调度或者未配置其对应的载波。
通过本发明的上述方法,基站通过第一DCI动态指示UE所调度的载波,UE只需要针对所调度载波进行DCI盲检测即可,减少了盲检测带来的复杂度。
作为一个实施例,所述动态信令是下行调度DCI(即其DCI格式是1/1A/1B/1C/1D/2/2A/2B/2C/2D中的一种),所述处理是发送。
作为一个实施例,所述动态信令是上行调度DCI(即其DCI格式是0/4中的一种),所述处理是接收。
作为一个实施例,所述工作频带由中心频率和载波带宽两个参数指示。作为又一个实施例,所述工作频带由下载频和上载频指示,即所述工作频带是所述下载频和所述上载频之间的带宽。

上述方面的本质是采用高层信令半静态配置资源分配信息,考虑到非授权频谱上下行信道状态指示(CSI-Channel Status Indicator)信息的测量和反馈的频率/精度很可能较低,半静态配置资源分配信息不会带来大的性能损失。
具体的,根据本发明的一个方面,第一DCI在授权频谱上发送。
上述方面是通过授权频谱传输用于调度非授权频谱的第一DCI,避免了控制信令受到不可预测的干扰。

具体的,根据本发明的上述方面,第一DCI是由小区无线网络暂定识别号(C-RNTI:Cell Radio Network Temporary Identifier)标识的。
作为一个实施例,第一DCI是由C-RNTI扰码的。
作为又一个实施例,第一DCI位于UE搜索空间(USS-UE Search Space)中的候选位置是由C-RNTI标识的。

-第一信息是所述选项1还是所述选项2。
上述方面能够尽可能的降低第一DCI的负载尺寸。作为一个实施例,所述M等于所述N。作为又一个实施例,所述L是不小于log2N的最小正整数。作为又一个实施例,第一信息是所述选项1和所述选项2中具有较小负载尺寸的选项。
