相关申请的交叉引用
本申请要求2003年8月22日提交的题为“采用不对称的子带载波群的时-频分复用(T-FDM)和/或正交频分复用(OFDM)***和方法”的临时申请No.60/497269以及2004年8月9日提交的题为“采用具有不同数量子带载波的前向和/或反向链路载波的无线***、方法和设备”的实用新型申请的权益，这些申请的公开内容如同在此全面阐述一样，通过引用由此全部结合于此。
技术领域
本申请涉及通信***、方法和设备，更具体地说，涉及无线通信***、方法和设备。
背景技术
时-频分复用和/或时-频分多址(T-FDM/T-FDMA)和正交频分复用和/或正交频分多址(OFDM/OFDMA)***和方法广泛地用于有线和无线通信。本领域技术人员熟知：T-FDM/T-FDMA和OFDM/OFDMA是众所周知的频分复用和/或频分多址(FDM/FDMA)通信技术的比较近代的变化。通常，在FDM/FDMA通信***和方法中，通信频带被分为若干频率子带，在其上使用子带载波来发射信息。在传统的无线FDM/FDMA***中，在子带载波和用户之间有一对一的关系(一个子带载波仅分配给一个用户)，并且用户设备和/或***设备可能每载波辐射仅一个子带载波。传统的FDM/FDMA***的一个示例是仍旧在美国使用的模拟AMPS蜂窝通信***。传统的FDM/FDMA***的另一示例是目前由Mobile Satellite Ventures(MSV)运营的M-SAT移动卫星***(MSS)。Inmarsat也通过传统的FDM/FDMA技术提供MSS服务。
在此使用的频分复用和/或频分多址(FDM/FDMA)指通信***、方法、***设备和/或用户设备，其中通信频带被分为其上可存在共同地定义载波的多个子带载波的若干频率子带，并且其中可以通过可存在于通信频带之上的可能的多个子带载波中的至少一个子带载波来承载用户的信息。
在传统的FDM/FDMA通信***和方法中，一对一对应存在于仅一个子带载波和用户之间，并且用户设备和/或***设备可能每载波辐射仅一个子带载波，与之相对比，在此使用的FDM/FDMA通信***和方法、和/或OFDM/OFDMA和/或T-FDM/T-FDMA通信***和方法中，载波可被定义为包含不止一个子带载波以及与用户相关联的信息可能与不止一个子带载波相关联(通过不止一个子带载波传送/承载)。在OFDM/OFDMA通信***和方法中，在接收机观测时间，通过子带载波传送/承载的信息可以被调节以相对于通过属于相同和/或不同载波的任何其它子带载波承载的信息维持正交态。因此，依赖于时间正交性，在OFDM/OFDMA***和方法中，子带载波可在频率上最大地紧缩来最小化在相邻子带载波和/或相邻载波之间的频率间隔。OFDM/OFDMA***和方法的这种特征可以最大化频谱效率并且在发射机和/或接收机中可以不需要严格的频域滤波。与之不同，在非OFDM/OFDMA***中(如在FDM/FDMA和/或T-FDM/T-FDMA***中)，分离不同子带载波和/或不同载波承载的信号的能力典型地通过子带和/或载波滤波器的频率选择性取得。子带载波还可在多个用户之间在时间和/或在频率中复用(时-频分复用和/或时-频分多址)，导致组合的频和时分复用/多址(T-FDM/T-FDMA)的通常例子。会理解到在此使用的OFDM/OFDMA可代表T-FDM/T-FDMA和/或FDM/FDMA的特例，其中时间正交态可存在于由相同和/或不同的载波的不同子带载波承载的信息单元之间。码分多址(CDMA)技术还可用来在一个或多个子带载波上复用多个用户。
在例如美国专利6603734；6567374；6377566；6345036；6160791；6021110和5889759中描述了OFDM***和方法。还在题为“用于移动数据通信的OFDM”的指南中描述了OFDM，该指南由国际工程联盟公布在网上，可以在iec.org的网上得到。OFDM还用于有线通信，例如在数字用户线(DSL)技术中。还使用不对称数字用户线(ADSL)技术来提供具有不对称数据速率的DSL服务。参见例如由DSL论坛(2001)发布的“ADSL指南”。
发明内容
本发明的实施例提供无线FDM/FDMA***、方法和/或设备，如无线T-FDM/T-FDMA和/或OFDM/OFDMA***、方法和/或设备，其中定义载波的子带载波群在它的前向和反向链路之间以非对称方式提供。而且，在一些实施例中，不同的前向链路载波可含有不同数量的子带载波，以及不同反向链路载波可含有不同数量的子带载波。在此使用的前向链路是从无线***设备到无线用户设备传送用户信息的无线链路，而反向链路是从无线用户设备到无线***设备传送用户信息的无线链路。
而且，在一些实施例中，反向链路载波由比对应的前向链路载波更少的子带载波构成。在另一些实施例中，反向链路载波由单一子带载波构成。还会提供模拟无线用户设备、***设备和操作无线用户设备和无线***设备的方法。
附图说明

具体实施方式
现在将参考示出了本发明的实施例的附图在下文中更全面地描述本发明。然而本发明可以实现为许多不同的形式，不应看作是受限于在此阐述的实施例。相反，提供这些实施例是为了使该公开透彻和完全，并且会把本发明的范围全面地传达给本领域的技术人员。全文中相似的标记指相似的单元。
会理解到尽管术语第一和第二被用于此来描述各种单元，但是这些单元不应受限于这些术语。这些术语仅仅用于把一个单元与另一单元区分开来。因此，下文中的第一单元能称作第二单元，以及类似地，第二单元可称作第一单元而不会背离本发明所教授的内容。在此使用的术语“和/或”包括一个或多个相关联的所列出术语的任何和所有的组合。符号“/”也用作“和/或”的简化符号。而且除非上下文清楚指出，否则在此使用的单数形式“a”、“an”和“the”也意味着包括复数形式。还会理解到当在此使用术语“包括”和/或“包含”时，规定了陈述的特征、整数、步骤、操作、单元和/或组件的存在，但并不排除存在或增加一个或多个其它特征、整数、步骤、操作、单元、组件和/或它们的群。与之对比，在此使用的术语“由……组成”规定了陈述的子带载波的数量并排除附加的子带载波。
根据本发明的实施例的无线FDM/FDMA通信***、方法和/或设备，如无线T-FDM/T-FDMA和/或OFDM/OFDMA通信***、方法和/或设备可按照包含在前向和/或反向链路载波之间非对称布置的子带载波群的通信协议进行工作。如图1和2所示，前向链路载波110由一群N个子带载波112组成，而对应的反向链路载波120由一群M个子带载波122组成，其中M小于N(M＜N)。由一群N个子带载波112组成的前向链路载波用于从无线***设备(如图1中的陆地基站130和/或图2中的卫星230)到无线用户设备140发射信息，而由一群M个子带载波122组成的反向链路载波用于从无线用户设备140到无线***设备130和/或230发射信息。会理解到无线用户设备140和无线***设备130和/或230可包括配置成发射和接收这些载波的收发信机(发射机/接收机)。
在此使用的术语“无线用户设备”140包括：蜂窝和/或具有或没有多行显示的卫星无线电话；可以把无线电话与数据处理、传真和/或数据通信能力结合的个人通信***(PCS)终端；能包括射频收发信机和寻呼机、因特网/内部网接入、万维网浏览器、管理器、日历和/或全球定位***(GPS)接收机的个人数字助理(PDA)；和/或包括射频收发信机的常规的膝上型电脑和/或掌上电脑或其它器具。在此使用的术语“无线用户设备”140还包括任何其它的辐射用户设备/装置/源，其可具有时变或固定的地理坐标以及可以是便携的、可运输的、安装在运输工具(航空的、海上的或陆上的)中、或被设置和/或配置成局部地和/或分布式地在地球上和/或在空间中的任何其它位置工作。术语“无线电终端”、“无线电话”或简单的“终端”还可用来表达同术语无线用户设备相同的意思。而且，在此使用的术语“无线***设备”包括配置成为了无线地向至少一个无线用户设备发射信息来辐射电磁能量的***设备(不是最终用户装置，如基站130和/或卫星230)的任何组合。
而且，在此使用的陆地基站130包括常规的蜂窝基站和/或辅助陆地组件(ATC)。在以下专利中描述了ATC：Karabinis的题为“蜂窝卫星频谱的陆地再用的***和方法”的美国专利6684057；和Karabinis的题为“蜂窝卫星频谱的陆地再用的***和方法”的公布的美国专利申请US 2003/0054760；Karabinis的题为“卫星频率的陆地再用的空间保护带”的US 2003/0054761；Karabinis等人的题为“监视陆地再用的卫星频率以降低可能干扰的***和方法”的US2003/0054814；Karabinis的题为“多波段/多模式卫星无线电话通信***和方法”的US 2003/0054762；Karabinis的题为“使用卫星链接的远程终端接口子***的无线通信***和方法”的US 2003/0153267；Karabinis的题为“降低蜂窝卫星***中的卫星馈线链路带宽/载波的***和方法”的US 2003/0224785；Karabinis等人的题为“配合的卫星-陆地频率再用”的US 2002/0041575；Karabinis等人的题为“使用信号衰减和/或阻塞、频率和/或滞后的动态分配的卫星-陆地频率再用的集成或自主***和方法”的US 2002/0090942；Karabinis等人的题为“卫星无线电话***的基于空间的网络体系结构”的US2003/0068978；Karabinis的题为“用于组合无线电话/GPS终端的滤波器”的US 2003/0143949；Karabinis的题为“卫星频率的陆地再用的交错分区”的US 2003/0153308；以及Karabinis的题为“响应于卫星频率的陆地再用修改卫星天线小区方向图的方法和***”的US2003/0054815，所有的上述专利被转让给本发明的受让人，如同在此全面阐述一样，所有的它们的公开内容通过引用由此全部结合于此。
前向链路110或反向链路120载波的子带载波的占有带宽可能与相同或其它前向和/或反向链路载波的任何其它子带载波的占有带宽完全相同、基本相同或不同。反向链路子带载波122可具有帧结构，并且可基于时分复用和/或时分多址(TDM/TDMA)、码分复用和/或码分多址(CDM/CDMA)、频分复用和/或频分多址(FDM/FDMA)和/或任何其它的复用/多址原理。前向链路子带载波112可具有帧结构，并且可支持时分复用和/或时分多址(TDM/TDMA)、码分复用和/或码分多址(CDM/CDMA)、频分复用和/或频分多址(FDM/FDMA)和/或任何其它的复用/多址技术。在相同和/或不同前向链路110和/或反向链路120载波的子带载波之间使用的子带载波调制可以是完全相同、基本相同或不同的。可与子带载波相关联的声码器和可与任何其它的相同和/或不同前向链路110和/或反向链路120载波的子带载波相关联的声码器可能完全相同、基本相同或不同。相似地，可用于保护子带载波上的信息的前向纠错编码(FEC)和/或交织和可用于保护任何其它的相同和/或不同前向链路110和/或反向链路120载波的子带载波上的信息的FEC和/或交织可以完全相同、基本相同或不同。
根据本发明的一些实施例，使每个反向链路载波(子带载波群)的子带载波122的数量等于一(M＝1)，并且把全部或基本全部的子带载波帧分配到一个无线用户设备140。相对于由多个子带载波组成和/或其中发射帧被多个用户共享的反向链路载波，这能允许无线用户设备140把信息连续或基本连续地及时发射到***，能增加或最大化无线接收机的Eb/No工作点，和/或能降低或最小化发射设备的功率输出。这些实施例在无线通信***和方法、特别是在卫星***和方法上的应用可允许这样的***和方法以在它们反向链路上增加的链路可靠性(链路裕度)工作。
根据本发明的一些实施例，第一反向链路载波的子带载波122的数量不同于第二反向链路载波的子带载波122的数量和/或第一前向链路载波的子带载波112的数量不同于第二前向链路载波的子带载波112的数量。换言之，在本发明的一些实施例中，N能在前向链路的不同前向链路载波之间变化和/或M能在反向链路的不同反向链路载波之间变化。可使用本发明的该方面来最大化或改善其中***可用频带可包含多个不连续的频段的***中(例如在L-带***中)的频谱利用和/或频谱效率。
在附图和说明书中，公开了本发明的实施例，并且，尽管采用了专门术语，但它们也仅被使用在一般和说明的意义上而非为了限制的目的，本发明的范围在下面的权利要求中阐述。
