Description

用于在无线通信系统中处理多码字分配的方法和设备
基于35U.S.C.§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 ANDAPPARATUS FOR PROVIDING MOBILE BROADBAND WIRELESSHIGHERMAC”的临时申请No.60/731,037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
本公开文件一般涉及无线通信，更具体地，涉及通过接入终端来处理多码字分配的方法和设备。
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。无线通信设备已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。
发明内容
下面给出对一个或多个实施例的简要概述，以提供对这些实施例的基本理解。该概述不是对全部预期实施例的广泛概括，也不旨在标识全部实施例的关键或重要元件或者描述任意或全部实施例的范围。其目的仅在于做为后文所提供更详细描述的序言，以简化形式提供一个或多个实施例的一些概念。
根据实施例，提供了用于处理多码字分配的方法，该方法包括：接收MCW-FLAB1，确定根据具有补充字段的SS MAC协议所接收的具有接入终端的MACID的MCW-FLAB1中的补充字段的值，确定在同一PHY帧中是否接收了具有MACID的MCW-FLAB2，以及基于补充字段的值和是否接收了MCW-FLAB2来处理MCW-FLAB1。
根据另一个实施例，描述了一种计算机可读介质，其具有：第一指令集，用于接收MCW-FLAB1第二指令集，用于确定根据具有补充字段的SS MAC协议所接收的具有接入终端的MACID的MCW-FLAB1中的补充字段的值；第三指令集，用于确定在同一PHY帧中是否接收了具有MACID的MCW-FLAB2，以及第四指令集，用于基于补充字段的值和是否接收了MCW-FLAB2来处理MCW-FLAB1。
根据另一个实施例，描述了一种可操作在无线通信系统中的设备，其包括：用于接收MCW-FLAB1的模块；用于确定根据具有补充字段的SSMAC协议所接收的具有接入终端的MACID的MCW-FLAB1中的补充字段的值的模块；用于确定在同一PHY帧中是否接收了具有MACID的MCW-FLAB2的模块；以及用于基于补充字段的值和是否接收了MCW-FLAB2来处理MCW-FLAB1的模块。
为了实现前述和相关目的，所述一个或多个实施例包括后面充分描述以及在权利要求书中具体指出的特征。以下描述和附图具体提供了所述一个或多个实施例中的某些示例性实施例。然而，这些实施例仅仅指示可采用不同实施例的原理的一些不同方式，所描述的实施例旨在包括全部这种实施例及其等效物。

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1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(UE)、无线通信设备、终端、移动台或一些其它术语，并且包括UE、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1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”的未决美国专利申请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个发射机(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，并且进一步调整(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NR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的运行可采用的采样率、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个发射符号流。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)“连续置空/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示出了接入终端402和接入网络404之间的通信。接入网络404将具有补充字段集的MCW-FLAB1分配块408发送到接入终端402。通过使用通信链路406并且基于预定的时序、系统条件或其它决定性标准，接入网络404将块408发送到接入终端402。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、

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)、正交频分复用闪存(OFDM-FLASH)、全球移动通信系统(GSM)、单载波(1X)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(HSDPA)、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。
接入网络404用于将块408发送到接入终端402。接入网络404可以将消息408合并到在前向链路406上发送的数据分组或多个数据分组412中。在另一个实施例中，无需将消息408合并到分组中就可以发送消息408。数据分组包括头部信息，用于指示数据分组412是否包括MCW-FLAB1块408。在前向链路406上使用一个或多个信道来交换数据分组412。接入网络404还可以将MCW-FLAB2块与MCW-FLAB1块一起发送到接入终端。接入终端402用于接收通信链路406上的数据分组412，其中一个数据分组可以包括MCW-FLAB1块408。
在接入终端402可以使用多种方法来从前向链路中提取消息408。例如，一旦接入终端402从前向链路的其中一个信道中提取了数据分组412，它可以检查数据分组412的头部信息，以确定数据分组412是否包括MCW-FLAB1块408。如果包括MCW-FLAB1块408，则接入终端402从块408中提取指定的比特，并且将值储存在存储器中(例如图2中的存储器232)。接入终端402可以，但是并非必须，在通信链路406上用ACK或NACK消息410来进行响应，并且基于补充字段的值以及是否接收了MCW-FLAB2来继续处理MCW-FLAB1块。如果接入终端402根据补充字段被设置为‘0’的SS MAC协议接收了具有接入终端MACID的MCW-FLAB1，则在同一PHY帧中可以接收有具有接入终端MACID的MCW-FLAB2，否则，接入终端402可以忽略该MCW-FLAB1消息。如果接入终端402根据补充字段被设置为‘1’的SS MAC协议接收了具有接入终端MACID的MCW-FLAB1，则如果在同一PHY帧中没有接收到具有接入终端MACID的MCW-FLAB2，则接入终端可以使用第2层及其以上的层当前的分组格式(只要存在MCWFLAB类型的现有ATA)。否则，如果在同一PHY帧中接收到具有接入终端MACID的MCW-FLAB2，则接入终端可以根据MCW-FLAB2来更新第2层及其以上的层的分组格式。
图5A根据实施例，示出了处理500的流程图。在502，在接入终端接收MCW-FLAB1。在504，确定在接入终端根据SS MAC协议所接收的具有接入终端MACID的MCW-FLAB1中的补充字段的值。在506确定在同一PHY帧中是否接收了具有接入终端MACID的MCW-FLAB2。在508，基于补充字段的值并且基于是否在同一PHY帧中接收到具有接入终端的MACID的MCW-FLAB2来处理MCW-FLAB1。
图5B示出了用于处理MCW-FLAB1块的处理器550。根据实施例，所涉及的处理器可以是电子器件并且可以包括用于处理MCW-FLAB1的一个或多个处理器。处理器552用于在接入终端处接收MCW-FLAB1。处理器554用于确定在接入终端根据SS MAC协议所接收的具有接入终端MACID的MCW-FLAB1中的补充字段的值。进一步地，处理器556用于确定在同一PHY帧中是否接收了具有接入终端MACID的MCW-FLAB2，处理器558用于基于补充字段的值并且基于是否在同一PHY帧中接收到具有接入终端的MACID的MCW-FLAB2来处理MCW-FLAB1。可以将图中描述的离散的处理器552到558功能组合到单个的处理器560中。存储器562也耦合到处理器560。
在实施例中，描述了一种设备，其包括用于在接入终端接收MCW-FLAB1的模块。提供了用于确定在接入终端根据SS MAC协议所接收的具有接入终端MACID的MCW-FLAB1中的补充字段的值的模块。进一步地，提供了用于确定在同一PHY帧中是否接收了具有接入终端MACID的MCW-FLAB2的模块，并且提供了用于基于补充字段的值并且基于是否在同一PHY帧中接收到具有接入终端的MACID的MCW-FLAB2来处理MCW-FLAB1的模块。本文描述的模块可以包括一个或多个处理器。
此外，可以由硬件、软件、固件、中间件、微代码或其任意组合实现所述实施例。当在软件、固件、中间件或微代码中实现时，执行所需任务的程序代码或代码段可被存储在机器可读介质中，例如未示出的分立存储器。处理器可以执行所需任务。代码段可以代表过程、函数、子程序、程序、例程、子例程、模块、软件包、类或者指令、数据结构或程序声明的任意组合。可以通过传递和/或接收信息、数据、变量、参数或存储器内容，将一个代码段耦合到另一个代码段。可以经由包括存储器共享、消息传递、令牌传递、网络传输等任意适当方式，将信息、变量、参数、数据等进行传递、转发或发送。
对于本领域技术人员而言，对所述实施例的各种修改将是显而易见的，并且本文所定义的一般性原理可被应用到其它实施例。因此，本说明书并非旨在局限于所示出的实施例，而应给予与本文所公开的原理和新颖特征相一致的最宽范围。
