用于在无线通信系统中处理处于开放状态的所选交织操作的

方法和装置

基于35 U.S.C.S.119要求优先权

本专利申请要求于2005年10月27日递交的、名称为"METHODS AND APPARATUS FOR PROVIDING MOBILE BROADBAND WIRELESS LOWERMAC"的临时申请No.60/731,126的优先权,该临时申请被转让给 本申请的受让人,通过参考将其明确地并入本文。

技术领域

本发明一般涉及无线通信,更具体地,涉及用于处理处于开放状态的 所选交织操作的方法和装置。

背景技术

无线通信系统已经成为世界范围内大多数人实现通信所利用的普遍手 段。无线通信设备己变得更小且功能更强大,以便满足消费者的需求以及 提高便携性和便利性。在例如蜂窝电话的移动设备中处理能力的提高导致 了对无线网络传输系统的要求的提高。典型地,这种系统不能象在其上进 行通信的蜂窝设备一样易于更新。随着移动设备性能的扩展,难以用便于 充分开发新的改进的无线设备性能的方式来维护原有无线网络系统。

无线通信系统一般利用不同的方法来生成信道形式的传输资源。所述 系统可以是码分复用(CDM)系统、频分复用(FDM)系统以及时分复用

(TDM)系统。正交频分复用(OFDM)是FDM的一种常用变型,其有效 地将整个系统带宽分为多个正交子载波。所述子载波也可称为音调、频段

(bin)和频道。每个子载波可调制有数据。利用基于时分的技术,每个子 载波可以包括连续时间片或时隙的一部分。可以为每个用户提供一个或更 多时隙以及用于在指定突发周期或帧内发送和接收信息的子载波组合。跳 变方案一般可以是符号率跳变方案或块跳变方案。

典型地,基于码分的技术在一定范围内任意时刻处可用的多个频率上 发送数据。通常,数据被数字化并在可用带宽上扩展,其中多个用户可以 在信道上重叠,并且各个用户可被分配唯一序列码。用户可以在频谱的相 同宽频带内发送数据,其中利用每个用户各自的唯一扩展码在整个带宽上 对每个用户的信号进行扩展。该技术能够提供共享,其中一个或多个用户 能够同时进行发送和接收。所述共享可以通过扩展频谱数字调制来实现, 其中以伪随机的形式对用户的比特流进行编码并在较宽的信道上进行扩 展。接收机被设计用来识别相关联的唯一序列码以及去除随机化,以便用 相干方式收集特定用户的比特。

典型的无线通信网络(例如,采用频分、时分和/或码分技术)包括提 供覆盖区域的一个或多个基站以及能够在覆盖区域内发送和接收数据的一 个或多个移动(例如,无线)终端。典型的基站能够同时发送多个数据流, 以用于广播、多播和/或单播服务,其中数据流是能够独立接收的、移动终 端所期望的数据的流。基站覆盖区域内的移动终端可能期望接收一个、一 个以上或全部发自基站的数据流。同样,移动终端能够向基站或其它移动 终端发送数据。在所述系统中,利用调度器分配带宽和其它系统资源。

与公知手段相比,本文所公开的信号、信号格式、信号交换、方法、 处理和技术提供了若干优势。这些优势包括,例如,减少的信令开销、改 善的系统吞吐量、提高的信令灵活性、减少的信息处理、降低的传输带宽、 减少的比特处理、增强的健壮性、改进的效率以及减少的传输功率。

具体实施方式

现在参照附图描述多个实施例,其中用相同的参考标号指示本文中的 相同元件。在下面的描述中,为便于解释,提出了大量具体细节,以便提 供对一个或多个实施例的全面理解。然而,显然地,可以在不具有这些具 体细节的情况下实现所述实施例。在其它例子中,以方框图形式示出公知 结构和设备,以便于描述一个或多个实施例。

参照图1,示出根据一个实施例的多址无线通信系统。多址无线通信系

统100包括多个小区,例如,小区102、 104和106。在图l的实施例中, 每个小区102、 104和106可以包括接入点150,其包括多个扇区。所述多 个扇区由多个天线所构成的组形成,其分别负责在小区的一部分中与接入 终端进行通信。在小区102中,天线组112、 114和116分别对应不同扇区。 在小区104中,天线组118、 120和122分别对应不同扇区。在小区106中, 天线组124、 126和128分别对应不同扇区。

每个小区包括若干接入终端,这些接入终端与每个接入点的一个或多 个扇区进行通信。例如,接入终端130和132与基站142进行通信,接入 终端134和136与接入点144进行通信,以及接入终端138和140与接入 点146进行通信。

控制器130耦合到各个小区102、 104和106。控制器130可以包含与 例如互联网、其它基于分组的网络或电路交换语音网络等多个网络的一个

或多个连接,其中所述网络在与多址无线通信系统100的小区进行通信的 过程中,向接入终端提供信息以及从接入终端获得信息。控制器130包括 调度器或耦合到调度器,所述调度器对来自和发向接入终端的传输进行调 度。在其它实施例中,调度器可以位于每个独立小区中、小区的每个扇区 中或者其组合中。

如本文所使用的,接入点可以是用于与终端进行通信的固定站,也可 被称为基站、节点B或一些其它术语,并且包括基站、节点B等的部分或 全部功能。接入终端也可被称为用户设备(l正)、无线通信设备、终端、移 动台或一些其它术语,并且包括l正、无线通信设备、终端、移动台等的部 分或全部功能。

应当注意,尽管图l示出物理扇区,即,对于不同扇区具有不同天线, 但是也可以利用其它方法。例如,可以利用在频率空间中分别覆盖小区不 同区域的多个固定"波束"来替代物理扇区或与物理扇区组合。在名称为 "Adaptive Sectorization in Cellular System "的未决美国专禾'J申i青 No.11/260,895中描述并公开了这种方法。

参照图2,示出MIMO系统200中发射机系统210和接收机系统250 的实施例的方框图。在发射机系统210处,将大量数据流的业务数据从数 据源212提供到发射(TX)数据处理器214。在实施例中,在相应的发射 天线上发送每个数据流。TX数据处理器214基于为每个数据流选择的特定 编码方案,对该数据流的业务数据进行格式化、编码和交织,以提供编码 数据。

可以使用OFDM或者其它正交或非正交技术,将每个数据流的编码数 据与导频数据进行复用。典型地,导频数据是公知的数据类型,其以公知 的方式进行处理,并且可在接收机系统处被用于估计信道响应。然后,基 于为每个数据流选择的一个或多个特定调制方案(例如,BPSK、 QSPK、 M-PSK或M-QAM),对该数据流的复用导频和编码数据进行调制(即,符 号映射),以提供调制符号。可以利用由处理器230提供并在其上执行的指 令,确定每个数据流的数据速率、编码和调制。

然后,将全部数据流的调制符号提供到TX处理器220,其可以进一步 处理所述调制符号(例如,用于OFDM)。然后,TX处理器220向Nt个友 射机(TMTR) 222a到222t提供NT个调制符号流。每个发射机222接收并 处理相应的符号流以提供一个或多个模拟信号,并且迸一步调整(例如, 放大、滤波和上变频)所述模拟信号以提供适于在MIMO信道上传输的调 制信号。然后,分别从NT个天线224a到224t发送来自发射机222a到222t

的NT个调制信号。

在接收机系统250处,所发送的调制信号由Na个天线252a到252r进 行接收,并且来自每个天线252的接收信号被提供到相应的接收机(RCVR) 254。每个接收机254调整(例如,滤波、放大和下变频)相应的接收信号, 对所调整的信号进行数字化以提供采样,并且进一步处理所述采样以提供 相应的"接收"符号流。

然后,RX数据处理器260基于特定的接收机处理技术,接收并处理来 自Nr个接收机254的Nr个接收符号流,以提供Nt个"检测"符号流。下 面进一步详细描述RX数据处理器260的处理。每个检测符号流包括多个符 号,所述符号是对针对相应数据流所发送的调制符号的估计。然后,RX数 据处理器260对每个检测符号流进行解调、去交织和解码,以恢复数据流 的业务数据。RX数据处理器218的处理与在发射机系统210处TX处理器 220和TX数据处理器214所执行的处理互补。 对于RX数据处理器260,可以限制其可同时解调的子载波的数量,例 如,512个子载波或5MHz,并且应当在单个载波上调度这种接收机。该限 制可能是其FFT范围所导致的,例如处理器260的运行可采用的釆样率、 FFT可用的存储器或者其它解调可用的功能。此外,所利用的子载波的数 量越多,接入终端的花费就越多。

由RX处理器260生成的信道响应估计可被用于在接收机处执行空间、 空间/时间处理,调整功率电平,改变调制速率或方案,或者其它操作。RX 处理器260还可以估计检测符号流的信号-噪声干扰比(SNR)以及可能的 其它信道特性,并将这些数量提供给处理器270。 RX数据处理器260或处 理器270还可以导出对系统的"运行"SNR的估计。然后,处理器270提 供信道状态信息(CSI),其可以包括关于通信链路和/或接收数据流的各种 类型的信息。例如,CSI可以仅包括运行SNR。在其它实施例中,CSI可以 包括信道质量指示符(CQI),其可以是指示一个或多个信道状况的数值。

然后,CSI由TX数据处理器278处理、由调制器280调制、由发射机254a 到254r调整以及被发送回发射机系统210。

在发射机系统210处,来自接收机系统250的调制信号由天线224接 收、由接收机222调整、由解调器240解调以及由RX数据处理器242处理, 以恢复由接收机系统报告的CSI。然后,所报告的CSI被提供给处理器230, 并被用于(1)确定用于数据流的数据速率以及编码和调制方案,以及(2) 生成对TX数据处理器214和TX处理器220的各种控制。可选地,CSI可 以由处理器270用来确定用于传输的调制方案和/或编码速率以及其它信 息。然后,将所述信息提供给发射机,所述发射机使用可能被量化的所述 信息来提供向接收机的后续传输。

处理器230和270分别指示在发射机和接收机系统处的操作。存储器 232和272分别对处理器230和270所使用的程序代码和数据提供存储。

在接收机处,可以将各种处理技术用于处理Nr个接收信号,以检测 Nt个友射符号流。这些接收机处理技术可以主要分为两类:(i)空间和空-时接收机处理技术(也被称为均衡技术);以及(ii)"连续置零/均衡和干扰 消除"接收机处理技术(也被称为"连续干扰消除"或"连续消除"接收 机处理技术)。

尽管图2说明了一种MIMO系统,但是也可将同样的系统应用于多输 入单输出系统,其中,多个发射天线(例如基站上的那些天线)向单天线 设备(例如移动台)发送一个或多个符号流。此外,可以用与针对图2所 描述的相同方式来使用单输出-单输入天线系统。

可以通过各种方式实现本文所描述的传输技术。例如,这些技术可以 在硬件、固件、软件或其组合中实现。对于硬件实现,发射机处的处理单 元可以在一个或多个专用集成电路(ASIC)、数字信号处理器(DSP)、数 字信号处理设备(DSPD)、可编程逻辑器件(PLD)、现场可编程门阵列 (FPGA)、处理器、控制器、微控制器、微处理器、电子设备、被设计用 于执行本文所描述功能的其它电子单元或其组合内实现。接收机处的处理 单元也可以在一个或多个ASIC、 DSP、处理器等内实现。

对于软件实现,可以用执行本文所描述功能的模块(例如,程序、函 数等)来实现所述传输技术。软件代码可被存储在存储器(例如,图2中

的存储器230、 272x或272y)中,并由处理器(例如,处理器232、 270x 或270y)执行。所述存储器可以在处理器内部或处理器外部实现。

应当注意,本文中信道的概念是指可由接入点或接入终端发送的信息 或传输类型。其不需要或利用固定的或预定的子载波块、时间周期或者专 用于这种传输的其它资源。

参照图3A和图3B,示出用于多址无线通信系统的超帧的实施例。图 3A示出用于频分双工(FDD)多址无线通信系统的超帧结构的实施例,而 图3B示出用于时分双工(TDD)多址无线通信系统的超帧结构的实施例。 可以针对每个载波单独发送超帧前导码,或者超帧前导码可以覆盖扇区中 的全部载波。

在图3A和图3B中,前向链路传输被分为多个超帧单元。超帧可以由 超帧前导码及其后跟有的帧序列构成。在FDD系统中,反向链路和前向链 路传输可能占用不同的频率带宽,使得这两个链路上的传输不会或大部分 不会在任意频率子载波上重叠。在TDD系统中,N个前向链路帧和M个 反向链路帧定义了在允许传输相反类型的帧之前,可以持续发送的连续前 向链路和反向链路帧的数量。应当注意,在给定的超帧内或在超帧之间, 数值N和M可以不同。

在FDD和TDD系统中,每个超帧可包括超帧前导码。在某些实施例 中,超帧前导码包括:导频信道,其包括可被接入终端用于进行信道估计 的导频;广播信道,其包括接收终端可用来解调包含在前向链路帧中的信 息的配置信息。此外,在超帧前导码中也可以包括使得接入终端足以在一 个载波上进行通信的例如时序和其它信息的采集信息,以及基本功率控制 或偏移信息。在其它情况中,在超帧前导码中仅仅包括上述和/或其它信息 中的一部分。

如图3A和图3B中所示,超帧前导码后跟有帧序列。每个帧可以由相 同或不同数量的OFDM符号组成,其可以构成可同时用于在某指定周期内 进行传输的多个子载波。此外,每个帧可以根据符号率跳变模式或块跳变 模式进行操作,其中,在符号率跳变模式中在前向链路或反向链路上为用 户指定一个或多个非连续OFDM符号,在块跳变模式中用户在一个OFDM 符号块内跳变。实际的块或OFDM符号可以或可以不在帧之间跳变。

图4相对于失调(Tune Away)示出了在接入终端402和接入网404之 间使用通信链路406的通信。这里讨论的Tune Away也可以应用于所有实 施例,其定义了一组重复的时间段,在该时间段期间,接入终端和接入网 之间不交换任何传输。Tune away的开始和结束可以由TuneAway属性以及 TuneAway请求和TuneAway响应消息来确定。此外,接入终端和接入网络 可以在多种time away调度方案上运行。可以使用多种通信协议/标准来实现 通信链路,所述通信协议/标准例如是微波接入全球互通(WiMAX)、例如 红外数据协会(IrDA)的红外协议、短距离无线协议/技术、Bluetooth⑧技 术、ZigBee⑧协议、超宽带(UWB)协议、家庭射频(HomeRF)、共享无 线接入协议(SWAP)、例如无线以太网兼容联盟(WECA)的宽带技术、 无线保真联盟(Wi-Fi联盟)、802.11网络技术、公共交换电话网络技术、 例如互联网的公共异类通信网络技术、专用无线通信网络、陆地移动无线 网络、码分多址(CDMA)、宽带码分多址(WCDMA)、通用移动电信系 统(UMTS)、高级移动电话服务(AMPS)、时分多址(TDMA)、频分多 址(FDMA)、正交频分复用(OFDM)、正交频分多址(OFDMA)、快闪式 正交频分复用(OFDM-FLASH)、全球移动通信系统(GSM)、单载波(IX) 无线传输技术(RTT)、仅数据演进(EV-DO)技术、通用分组无线业务 (GPRS)、增强数据GSM环境(EDGE)、高速下行链路数据分组接入 (HSPDA)、模拟和数字卫星系统以及可以在无线通信网络和数据通信网络 中的至少一个内使用的任意其它技术/协议。

接入终端402和接入网络404可以以所选交织启用模式或所选交织停 用(SdectedlnterlaceOff)模式进行操作。在所选交织启用模式中,接入网络 404在一组称为所选交织集的交织上向接入终端402发送SSCH块。在所选 交织停用模式中,对接入网络和接入终端没有限制。
