Description

无线网络中的联合传输
技术领域
一般来说，本申请涉及通过无线网络发送数据。本申请要求2011年9月30日提交的临时申请61/542086的优先权，该临时申请据此明确并入到本文。
背景技术
随着移动和无线网络越来越普及，无线电和无线通信标准必须适合于满足不断增加的带宽要求和用户需求。这些标准包括第三代合作伙伴计划（3GPP）长期演进（LTE）和高级长期演进（高级LTE）***。
利用这些协议，各种装置可以利用无线通信方案与数据网络通信。例如，每个装置可以建立到本地基站的无线连接以便接入到更宽的数据网络。因此，多个装置可以通过利用多个基站接入到数据网络来彼此通信。
附图说明
关于以下各图描述一些实施例：
图1是根据一个或多个实施例的实例网络配置的示意图；
图2是根据一个或多个实施例实例网络配置所使用的表格的描绘；
图3是根据一个或多个实施例的实例用户装置的示意图；
图4是根据一个或多个实施例的实例基站的示意图；以及
图5是根据一个或多个实施例的流程图。
具体实施方式
在无线通信中，协作多点（CoMP）传输会是一个特别令人感兴趣的领域。在CoMP下，多个基站能够同时向用户装置传送下行链路信号。然后，用户装置可以尝试同时解码所有下行链路信号，以便改善接收状况并增加数据吞吐量。
在3GPP LTE和高级LTE下，场景3下的一种类型的CoMP传输可以是联合处理。在联合处理过程中，多个基站可以彼此协调以便向以及从用户装置同时进行传送。因而，基站所发送的各种信号之间存在信号冲突的机会增加。例如，用于估计信道状况的参考信号可能会与包含用户数据的信号冲突和/或干扰包含用户数据的信号。因此，用户装置在解码和区分各种信号时可能会遭遇一些挑战。
用于减少用户数据和参考信号之间的干扰的一些策略可以包括在传输过程中对用户数据信号的某些部分进行静噪（muting）。尽管这样做可以减少干扰，但是对用户数据信号的部分进行静噪可能会减少到用户装置的数据吞吐量，并且可能会导致用户装置在信道估计过程中低估干扰等级。
图1代表根据一个或多个实施例在无线网络中用于从用户数据过滤参考信号数据的***100。***可以包括与多个基站130a-c通信的用户装置110。在一些实现中，用户装置110可以包括能够从基站130a-b同时接收多个信号的联合处理模块120。例如，每个基站130a-b可以向用户装置110发送参考信号140a-c和用户数据150a-c。
用户装置110可以是能够通过无线网络通信的任何电子装置。例如，用户装置110可以包括桌面型计算机、膝上型计算机、移动电话、平板个人计算机、个人数字助理、数字相机和/或任何其它电子装置。此外，尽管图1只示出一个用户装置110，但是应理解，任何数量的用户装置可以与基站130a-c通信。
在一些实现中，***100可以根据高级LTE规范操作。因而，基站130a-c可以称为演进节点B（eNB），而用户装置110可以称为用户设备（UE）。此外，***100能够利用协作多点传输（CoMP）场景3。具体来说，基站130a-c可以具有执行联合处理的能力以便协调同时到用户装置110的各种信号的传输。
因此，在一个或多个实施例中，这些信号中的一些信号可以包括参考信号140a-c和用户数据150a-c。例如，参考信号140a-c可以是发送到用户装置110以便执行信道估计的小区特有的参考信号（CRS）。用户装置110可以将参考信号140a-c在接收到时的特性与在发送它们时的特性进行比较。通过分析这些特性的任何差异，可以计算信道估计。
用户数据150a-c可以是包括图像数据、视频数据、媒体数据、控制数据和/或类似数据的任何数据。此外，可以根据高级LTE规范在物理下行链路共享信道（PDSCH）上发送用户数据150a-c。在利用基站130a-c的联合处理的一些实现中，参考信号140a-c和用户数据150a-c可能会经历彼此干扰。因此，联合处理模块120可以接收干扰信号，并过滤掉参考信号140a-c和/或用户数据150a-c中的一个或多个。
因此，联合处理模块120可以接收干扰信号，并过滤掉参考信号140a-c和/或用户数据150a-c中的一个或多个。在一些实施例中，联合处理模块120能够执行连续干扰消除（SIC）。SIC可以使得联合处理模块120能够同时解码两个或更多信号。例如，假设第一信号和第二信号同时到达联合处理模块120而形成组合信号，并且第一信号是两者中的较强者。利用SIC，联合处理模块120可以首先解码较强的第一信号，然后从组合信号中减去第一信号。因此，联合处理模块120能够接着从余数中提取较弱的第二信号。
在一些实施例中，联合处理模块120可以同时接收彼此干扰和/或冲突的参考信号140a-c和用户数据150a。在LTE和高级LTE下，这些冲突可能会出现在一个或多个冲突资源元素上。资源元素可以是LTE中的物理资源的基本单位，并且可以表示为编了索引的副载波和调制（例如，正交频分复用（OFDM））符号对。
因此，冲突资源元素可以包括参考信号140a-c和用户数据150a-c两者的叠加信号。由于参考信号140a-c可以是较强信号，所以联合处理模块可以首先检测参考信号140a-c并估计其信道响应。接着，联合处理模块120可以对叠加信号执行SIC以便过滤掉参考信号140a-c。即，可以从叠加信号重构和减去参考信号140a-c。作为减去的结果，可以检测和/或解码剩余的下行链路用户数据150a-c。
在一些实施例中，可以通过一对冲突的资源元素发送预编码数据符号。因此，在解码数据符号的过程中，冲突资源元素可以按对使用。例如，在消除这对冲突资源元素上的参考信号140a-c之后，这对资源元素中的每个资源元素可以包括预编码数据符号的部分。但是，由于进行了消除，所以仍然可能存在一些混淆数据符号的相干解码的噪声。因此，可以组合每个冲突资源元素上的剩余信号，并对这个组合信号执行数据符号的解码。
在一些实施例中，通过冲突资源元素从多个基站130a-c同时传送参考信号140a-c和用户数据150a-c可以视为是基站130a-c之间的空间复用形式。此外，从单个资源元素的角度来看，空间复用可以视为是数学表达式。例如，下文给出利用两个冲突资源元素（例如，来自两个不同的联合传输小区，例如基站130a-b）来传送一个用户数据150a-c资源元素（例如，PDSCH资源元素）的数学表达式。这些数学表达式可以是就LTE和/或高级LTE规范而言的。
可以把焦点放在图2的资源元素16上而做出以下表达式。首先，可以将通过两个冲突资源元素传送一个PDSCH资源元素表示为式(1)：

Figure DEST_PATH_IMAGE010
是小区i eNB的天线选择向量，例如；是当小区i发送参考信号ri时UE所看到的噪声向量。应注意，非冲突资源元素上的联合传输的完整波束形成矩阵是。即，冲突资源元素上的联合传输的完整波束形成矩阵分别是对应于P的上半部和下半部的
Figure DEST_PATH_IMAGE018
和
Figure DEST_PATH_IMAGE020
，其中
Figure DEST_PATH_IMAGE022
。换句话说，UE可以在每个冲突资源元素上观测到完整波束形成信道的不同部分。
在消除参考信号干扰之后，UE可以组合这两个部分观测以便获得如下的数据
Figure DEST_PATH_IMAGE006AA
的完整观测：
Figure DEST_PATH_IMAGE024
应注意，
Figure DEST_PATH_IMAGE026
是第k个资源元素上的联合传输的完整信道矩阵，并且是非冲突资源元素的波束形成矩阵。最后，UE可以利用参考信号以便利用来自冲突和非冲突资源元素的观测相干地解码PDSCH。诸如图2中的资源元素13、14和15的其它资源元素可以按类似的方式处理。
在LTE和/或高级LTE规范下的一些实施例中，可能希望用户装置以相对高的信号对干扰加噪声比（SINR）操作。因此，通常可以选择相对高的调制和编码方案（MCS）来进行从基站130a-c到用户装置110的PDSCH传输（即，用户数据150a-c的传输）。但是，选择用于进行来自特定基站的PDSCH传输的MCS越高，那么PDSCH传输可越易于受到来自其它基站的参考信号的干扰。此外，即使在如上所述执行了干扰消除之后，残余参考信号的干扰仍可能发生。换句话说，在联合传输方案下，利用相对高的MCS的PDSCH传输仍可能易于受到来自残余参考信号的干扰。
因此，在一个或多个实施例中，相对于用户装置所反馈的初始MCS等级，可以利用更低的MCS等级来在与参考信号140a-c冲突的资源元素（例如，图2中的资源元素14、16、18和20）上进行PDSCH传输。对于在PDSCH传输过程中没有经历任何冲突的其它资源元素，仍可以使用用户装置110所反馈的初始MCS等级。例如，假设用户装置110反馈了对应于64QAM的MCS等级。在这种场景下，PDSCH传送基站130a-c可以选择在与参考信号数据140a-c有冲突的资源元素中使用16QAM/QPSK，并在其它资源元素中维持64QAM。因此，在联合传输过程中，可以维持PDSCH传输的相对高的吞吐量，同时具有相对低的来自参考信号数据的干扰。
在其它实施例中，在任何PDSCH传输过程中，可以使用相对高的MCS等级。但是，用户装置110可以选择将相对高等级的MCS解调为较低等级的MCS。例如，用户装置110可以将一些位的对数似然比（LLR）设置为0。
图3代表图1的用户装置130的***描绘。用户装置可以包括用于接收数据的接收器310和用于传送数据的传送器320。在一个或多个实施例中，接收器310和传送器320可以组合以便形成既能够接收数据又能够传送数据的收发器。例如，接收器310可以从基站105接收参考信号120a-b，而传送器320可以将CSI信号125传送回到基站105。
另外，用户装置110还可以包括用于存储指令的存储器330和用于执行那些指令的处理器340。在一个或多个实施例中，联合处理模块120（未示出）可以包括处理器340和存储器330，或者可以以其它方式与处理器340和存储器330通信。在其它实施例中，联合处理模块120可以是存储在存储器330中的程序，并且从而提供指令以便供处理器340执行。因而，处理器340可以执行来自联合处理模块120的指令以便如上文参考图1所描述地那样执行干扰消除。
尽管图3只示出每种组件中的一个组件，但是应了解，在本公开内还预期这些组件的多个示例。例如，用户装置110也可以包括多于一个处理器和多于一个存储器。此外，用户装置110还可以包括多个存储装置。
类似地，图4代表可用于与其它基站130a-c执行到用户装置110的联合传输的实例基站130a-c的***描绘。因此，基站130a-c可以包括与图3的用户装置110中所示出的那些组件类似的组件。具体来说，基站130a-c也可以包括接收器410和传送器420、处理器440和存储器430。另外，基站105还可以包括用于在各种用户装置之间路由通信的路由器450。在一个或多个实施例中，存储器430可以存储图2中所示出的表200。
此外，基站130a-c还可以包括与处理器440和存储器460通信的联合传输逻辑（未示出）。在一个或多个实施例中，联合传输逻辑108可以包括处理器440和存储器430。在其它实施例中，联合传输逻辑130可以是存储在存储器430中的程序，并且从而提供指令以便供处理器440执行。因而，处理器440可以执行来自联合传输逻辑108的指令以便如上文参考图1所描述地那样确定联合传输信令。例如，联合传输逻辑108可以确定，对于特定PDSCH传输，将利用与从用户装置120反馈的初始MCS不同的MCS。
图5代表描绘根据一个或多个实施例用于在无线网络中执行联合传输的方法500的流程图。该方法可以在步骤510开始，此时用户装置从基站无线地接收多个冲突无线信号。冲突无线信号中的一个信号可以包括参考信号数据，而另一个无线信号可以包括用户数据。
接着，在步骤520，可以将参考信号数据和用户数据组合到叠加信号中。在步骤530，用户装置可以从叠加信号中过滤掉参考信号数据。如之前所论述的，该过程可以涉及通过用户装置进行的连续干扰消除。
最后，在步骤540，用户装置可以从叠加信号解码用户数据。因此，即使存在大量的信号冲突和干扰，用户装置仍能够接收来自多个基站的同时的联合传输。此外，可以接收这些联合传输，而不必对某些冲突用户数据资源元素进行静噪，这些冲突用户数据资源元素否则会降低到用户装置的用户数据吞吐量。
可以加载如上所述的软件指令（包括图5中所描述的步骤）以便在处理器（例如，图3和/或图4中示出的处理器）上执行。处理器可以包括微处理器、微控制器、处理器模块或子***、可编程集成电路、可编程门阵列、或其它控制或计算装置。如这里所使用的，“处理器”可以指单个组件或多个组件（例如，一个CPU或多个CPU）。
数据和指令存储在相应的存储装置中，存储装置作为一个或多个计算机可读或机器可读存储介质实现。存储介质包括不同形式的存储器，包括：半导体存储器装置，例如动态或静态随机存取存储器（DRAM或SRAM）、可擦除和可编程只读存储器（EPROM）、电可擦除和可编程只读存储器（EEPROM）和闪速存储器；磁盘，例如固定盘、软盘和可移动盘；其它磁介质，包括磁带；光介质，例如致密盘（CD）或数字视频盘（DVD）；或其它类型的存储装置。注意，以上论述的指令可以在一个计算机可读或机器可读存储介质上提供，或者备选地可以在分布在可能具有多个节点的大型***中的多个计算机可读或机器可读存储介质上提供。这种（或这些）计算机可读或机器可读存储介质视为是物品（或制品）的部分。物品或制品可以指任何制造的单个组件或多个组件。这个或这些存储介质可以设置在运行机器可读指令的机器中，或者设置在远距离站点处，可以通过网络从远距离站点下载机器可读指令以便用于执行。
在以上描述中，阐述了众多细节以便提供对本文公开的主题的理解。但是，没有这些细节中的一些或所有细节也可以实践实现。其它实现可以包括来自以上论述的细节的修改和改变。随附权利要求意欲涵盖这些修改和改变。
