Description

射频基站数据中继器
发明领域
本发明涉及到射频数据中继器，并且更加具体而言涉及到RF中继器的使用，即利用添加到中继信号当中的电子签名去提高信号噪声干扰比，从而消除位置测量误差。
发明背景
无线数据业务被用于电子邮件、互联网、公司信息和其它信息等的远端访问。为了吸引新用户以及现有用户使用数据业务，运营商需要支持能感觉得到的64kbps或者更高的数据速率。随着例如GPRS和EDGE等无线数据业务的部署，用户会逐渐发现随着从小区基站附近位置移动到小区边缘，他们可得到的数据速率会大大降低。典型地，在覆盖有限的部署方案中，估计能有不到20％的区域能够支持峰值数据速率。
无线网络目前已经得到改进，可以提供位置测量能力。这些方法提供给网络以估计移动单元位置的能力，例如用于紧急911(E911)移动电话业务。在基站内典型地插入位置测量单元(LMU)，利用到达时间(TOA)信息处理装置去估计从移动单元到LMU之间的距离，此时假设直线的无线传播。
RF中继器被用于增强在覆盖区域边缘处的移动台发射的信号。然而，由于经过该中继器的无线路径可能不是直接路径，因此LMU测量的距离也不与从LMU到发射移动单元的真正直线距离相对应。对中继移动信号来说，这会导致明显的位置测量误差。
用于解决错误E911LMU距离计算问题的当前方法就是：LMU与每个RF中继器处于同一位置，并且配备用于把距离测量信息传回基于网络的移动定位中心的装置。该方法至少在如下两点上，并不是十分有效的：第一，它要求在每个中继器站址处都配有一个LMU，这会增加成本，并且会造成每个中继器站址更加庞大笨重；以及第二，需要添加单独的数据链路或附加的数据比特，以便向基站发送距离信息。
相应地，需要具有如下能力的RF中继器：即在小区站址的选择区域内能够提高信号对噪声干扰比，特别是可以提供无线数据系统所要求的高数据速率。
相应地，需要具有如下能力的RF中继器：即利用独特的电子签名去标记经过中继器的信号，使得可以识别发射移动单元的真正位置。
发明概述
一方面，本发明提供一种数据中继器，其中在每方向上包含两个天线功能：接收和发送。在下行链路或前向方向中(基站到移动单元)，接收天线功能接收基站发出的信号，以及发送天线功能重新向移动单元发送下行链路信号。在上行链路或反向方向中(移动单元到基站)，接收天线功能接收移动单元发出的信号，而且发送功能重新向基站发送上行链路信号。
在一个实施例中，一个双工(组合不同频率的发送和接收)天线指向想要的基站的方向，而且另一个双工天线指向增加移动数据业务的想要的位置。天线被连接到RF处理模块，该模块分离下行和上行信号，对特定频段进行滤波，提供低噪声放大与发射机功率放大电路和用于标记上行信号的电路。
在该实施例中，数据中继器包含调谐到预定上行链路频段的双工天线。接收天线一旦接收到上行信号，就会将其传递给双工器(以便把该信号从发送的下行信号中分离出来)，并且再被传递到上行信号标记设备，该设备会在上行信号中引入独特的电子签名，以识别哪一个数据中继器被使用。可以通过把接收到的上行信号利用附加的非干扰直接序列扩频信号进行幅度或相位调制，从而执行信号标记。然后，把经过调制的上行信号传递到输出双工器，并且利用双工天线发送给基站。
在另一实施例中，数据中继器能够在经过中继器的下行和上行信号中引入信号标记。可以通过把接收到的下行和上行信号利用附加的非干扰直接序列扩频信号进行幅值或相位调制，从而执行信号标记。
在现有的和所提出的无线网络中，基站包括位置测量单元(LMU)，以便提供移动单元定位确定能力。LMU包含到达时间(TOA)接收机，以测量移动单元与LMU之间的传播时延，并且将这种时延测量转换为距离测量，此时假设直线传播。由于直线传播的假设不再是正确的，因此在网络中添加数据中继器会在位置确定中引入误差。
在优选实施例中，由数据中继器所引入的唯一上行信号标记可以被LMU内的附加电路进行检测。LMU内的伪随机(PN)码相关器检测上行信号标记，并且向移动定位中心(MLC)报告中继器标记ID。MLC根据TOA接收机测量值、所报告的中继器标记ID信息以及包括所标识中继器的地理坐标在内的数据库，去确定移动单元的真正位置。
相应地，本发明的目的之一在于增强在想要的区域内的信号电平，以支持更高的数据速率，而不必部署新的基站。本发明还有一个目的在于利用电子签名对经过中继器的上行信号进行标记，使得可以识别发射移动单元的真正位置。
本发明的另一目的在于利用电子签名对经过中继器的下行信号进行标记，使得可以识别发射基站的真正位置。
通过参考随后的规定、权利要求以及附图，本领域的技术人员可以进一步理解并且体会本发明的这些以及其它目的和好处。
附图简述
在此引入并且构成该技术规范的一部分的附图，其中说明了本发明的优选实施例，并且与如下描述一起，用于解释本发明的原理。在附图中，类似的参考符号始终如一地表示相应的功能。

详细描述
现在详细参考本发明的优选实施例，以及附图中说明的实例，其中在若干附图中，类似的参考数字表示类似的元素。
本发明提供具有如下能力的RF中继器：即在小区站址的选择区域内能够提高信号对噪声干扰比，特别是可以提供无线数据系统所要求的高数据速率。相应地，本发明可以提供具有如下能力的RF中继器：即利用唯一的电子签名去标记经过中继器的信号，使得可以识别发射移动单元的真正位置。
图1是无线通信小区站址的说明，其中包括由数据中继器所提供的额外高流量覆盖区域。基站10具有定义的覆盖区域或小区站址11。典型地，小区站址11内所选择的区域可以从数据速率改进中获得好处。通过把中继器20或多个中继器策略性地添加到小区站址当中，以提高这些特定覆盖区域内的信号噪声干扰比值。然而，由于经过该中继器20的无线路径可能不是直接的直线路径，因此LMU12所测量的距离不会与从LMU到达发射移动单元的真正直线距离相对应。对中继移动信号而言，这会导致明显的位置测量误差。
图2给出根据本发明的移动单元定位确定系统(MUPDS)的概要结构。MUPDS包含移动定位中心(MLC)1、基站10、LMU12以及中继器20。MLC利用由图5和6中所示的LMU12所提供的用户定位信息，去确定每个移动用户的位置。
图3给出根据本发明的包含上行信号标记的RF中继器的概念框图。在图3中，RF中继器中包括一个指向想要的基站方向的双工(合并不同频率的发射和接收)天线22，以及指向增加移动数据业务的想要的位置的另一双工天线23。天线22和23被连接到RF处理模块25，该模块分离下行和上行信号，并且通过滤波器/双工器26a和26b对特定频段进行滤波，提供低噪声放大和发射机功率放大电路27，调制电路28a和28b，以及用于标记上行信号的电路29a和29b。
在该实施例中，数据中继器20包含调谐到预定上行频段的双工天线23。接收天线一旦接收到上行信号，将其传递到滤波器/双工器26b(从被发送的下行信号中将其分离出来)，并且进一步被传递到上行信号标记电路29b，该电路在上行信号中引入独特的电子签名，以识别哪个数据中继器被使用。可以通过把接收到的上行信号与附加的非干扰直接序列扩频信号进行幅度或相位调制28b，来执行信号标记。然后，把经过调制的上行信号传递到输出双工器26a，并且利用双工天线22发送给基站。可以通过策略性地引入位于信号路径中的放大器27(如图3所示)，来实现信号的放大。
在另一实施例中，数据中继器能够在经过中继器的上行和下行信号中引入信号标记。可以如图4所示，通过把接收到的下行和上行信号与附加的非干扰直接序列扩频信号进行幅度或相位调制，来执行信号标记。在该实施例中，数据中继器20包含调谐到预定上行频段的双工天线23。接收天线一旦接收到上行信号，将其传递到滤波器/双工器26b(从被发送的下行信号中将其分离出来)，并且进一步被传递到上行信号标记电路29b，该电路在上行信号中引入电子签名，以识别哪个数据中继器被使用。可以通过把接收到的上行信号与附加的非干扰直接序列扩频信号进行幅度或相位调制28b，来执行信号标记。然后，把经过调制的上行信号传递到输出双工器26a，并且利用双工天线22发送给基站。此外，数据中继器20包含调谐到预定下行频段的双工天线23。双工天线22一旦接收到下行信号，将其传递到滤波器/双工器26a(从被发送的下行信号中将其分离出来)，并且进一步被传递到下行信号标记电路29a，该电路在下行信号中引入独特的电子签名，用于唯一的标识。可以通过把发送的下行信号利用附加的非干扰直接序列扩频信号进行幅度或相位调制28a，来执行信号标记。然后，把经过调制的下行信号传递到输出双工器26b，并且利用双工天线23发送给中继器或者直接发送给用户。可以通过策略性地引入位于信号路径中的放大器27(如图3所示)，来实现信号的放大。
图5给出根据本发明的包含检测标记信号的电路的位置测量单元(LMU)12的概念框图。在现有和所提出无线网络中，基站内包括可以提供移动单元定位确定能力的LMU12。LMU12中包含双工天线31、滤波器/双工器32、放大器33、混频器37、IF链路34以及I/Q解调器35。LMU实施方案的这一部分的公开阐述只是出于说明的目的。这一LMU部分的其它实施可以被本领域的技术人员所理解。在本发明中，LMU可以额外地包含到达时间(TOA)接收机36，以测量移动单元与LMU之间的传播时延，并且随后将这种时延测量转换为距离测量，此时假设直线传播。然而由于直线传播的假设不再是正确的，因此在网络中添加数据中继器会引入位置确定的误差。因此，独特的信号标记可以由如图3和4所示的PN序列生成器29a和29b引入。这些独特的信号标记可以由LMU内的伪随机(PN)码相关器38进行检测，其中检测信号标记，并且向MLC1报告中继器标记ID。MLC1根据TOA接收机测量、所报告的中继器标记ID信息以及包括所标识中继器的地理坐标在内的数据库2，去确定移动单元的真正位置。
可以理解到，还可以构造本发明的其它实施例，并且全部处于附加权利要求的精神实质和覆盖范围之内。
