用于控制信道信令的系统及方法
根据35U.S.C §119主张优先权
本申请案主张基于2005年4月1日提出申请的第60/667,705号美国临时专利申请案的优先权，所述临时专利申请案以引用方式全部并入本文中。

技术领域
大体来说，本发明涉及无线通信，且除其他以外，尤其涉及无线通信系统的信道信息反馈。 
背景技术
正交分频多址(OFDMA)系统利用正交频分多路复用(OFDM)。OFDM是一种多载波调制技术，其将整个系统带宽划分成多个(N)正交频率副载波。还可将这些副载波称为音调、频段及频率信道。每一副载波均与可使用数据对其进行调制的相应副载波相关联。在每一OFDM符号周期中，可将多达N个调制符号发送于总共N个副载波上。用N点快速傅立叶逆变换(IFFT)将这些调制符号转换至时域以产生包含N个时域片或样本的经变换符号。 
在跳频(FH)通信系统中，在不同时间间隔期间(可将称为“跳频周期”)将数据传输于不同的频率副载波上。可通过正交频分多路复用或其它多载波调制技术或某些其它构造来提供这些多载波。对于跳频来说，数据传输以伪随机方式从一个副载波跳跃到另一个副载波。这种跳跃可提供频率分集，并可使数据传输能够更好地抵挡诸如窄频干扰、拥塞、衰落等不利的路径效应。 
所有通信系统中都必须处理的一个问题是：可针对每一接入终端机使用多种传输技术中的不同传输技术。此外，接入终端机可与多个基站进行通信。所有这些排列都需要大量的反馈以便进行完整的报告。
因此，人们希望能够提供关于多个传输模式使用及关于与多个基站通信的反馈，而同时使将所述反馈从接收机提供至发射机所需的资源最小化。 
发明内容
本发明所提供的一个或多个方面可使不同扇区具有不同的反向链路报告类型。此外，所述报告类型可包括与接入终端机的正向链路传输类型相关的指令。所述报告类型还可与在所述接入终端机处正使用或正希望使用的调度模式相关。 
应理解，根据以下只以举例说明方式显示及阐述本发明只为例示性的方面的详细说明，所属技术领域的技术人员将明白本发明的其他方面。应认识到，本文所揭示的方面可还具有其它及不同的方面，且可从各个方面对其若干细节实施修改，此均不脱离本发明的范围。

具体实施方式
参照图1，图解说明根据一个方面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及106。在图1的方面中，每一小区102、104及106可包括一个包含多个扇区的接入点142、144或146。所述多个扇区由若干天线群组形成，每一天线组各自负责与所述小区的一部分中的接入终端机进行通信。在小区102中，天线群组112、114及116分别对应于不同的扇区。在小区102中，天线群组118、120及122各自对应于不同的扇区。在小区106中，天线群组124、126及128各自对应于不同的扇区。 
每一小区包括数个接入终端机，所述接入终端机可与每一接入点的一个或多个扇区进行通信。例如，接入终端机130及132与接入点142进行通信，接入终端机134及136与接入点144进行通信，且接入终端机138及140与接入点146进行通信。如本文中使用，来自接入点的传输被称为正向链路，而去往所述接入点的传输被称为反向链路。 
在某些方面中，每一接入终端机130、132、134、136、138及140可与一个或多个小区中的两个或更多扇区进行通信。可如此做以出于适当的容量管理及/或其他目的允许在不同扇区或小区之间进行越区切换。为提供能与多个扇区进行通信的能力，有用地，所述接入终端机可确定所述一个或多个扇区的信道状态。这可基于从所述一个或多个扇区所发射的导频或信标信号来完成。然后，可将所述信道信息(例如，信道质量信息(CQI))提供至所述一个或多个扇区的每一者，以针对往来于每一接入终端机的传输实现(例如)更为精确的功率、速率及其他控制，且支持软、较软及其他类型的越区切换。 
接入终端机具有可供其使用的指派资源(例如，媒体接入控制(MAC)ID)的扇区集合属于所谓接入终端机活动组。例示性活动组可由(例如)服务扇区120的接入终端机134连同扇区118、122、124及126组成。如本文所阐述，在这类情况下，扇区118、122、124及126可具有与接入终端机134的某种通信。 
应注意，虽然以上论述规定MACID是活动组中成员的资源，但除MACID之外，还可使用其他的资源(例如，来自与其或另一扇区的对话的对话信息、终端机ID或其他信息)，或可使用所述其他资源来替代MACID。 
最后一个所述接入终端机从其成功地接收正向链路指派的扇区可称为正向链路服务扇区(FLSS)。最后一个所述接入终端机从其成功地接收反向链路指派的扇区可称为反向链路服务扇区(RLSS)。经所述接入终端机确定为期望用于反向链路数据传输的扇区可称为期望反向链路服务扇区(DRLSS)。所述活动组中经接入终端机确定为期望用于正向链路数据传输的扇区可称为期望正向链路服务扇区(DFLSS)。 
所述活动组中的扇区为一个或多个同步子组的成员。不同的子组可具有不同的定时，例如，由不同的资源来同步。可将具有相同定时的扇区称为同步子组的成员。所述接入终端机的RLSS及FLSS可为相同同步子组中的成员从而可缓解用于控制消息的信令开销。在某些方面中，所述接入终端机可将DRLSS选为与RLSS在同一同步子组中的成员。不包含FLSS的同步子组称为非同步子组。 
在某些方面中，所述接入终端机最少能够传输可供FLSS使用的全部控制信道消息，除了那些特定用于除所述FLSS之外的扇区或接入点的控制信道消息以外。其还能够将这些消息传输至与所述FLSS在同一同步集合内的成员。另外，所述接入终端机可局限于仅将有限控制信道传输至为非同步子组中成员的每一扇区。 
拟报告至FLSS或任一其他扇区的实际控制信道消息以及其传输的频率及定时是基于来自FLSS或所述其他扇区的指令。所述指令可包括待发射控制信道的类型以及 其在帧、频率方面的定时，且可将传输的数量包含在所述指令或额外指令中。此外，可从一个或多个扇区提供对于单个实例报告的请求。此外，每一指令可构成对报告一个或多个控制信道类型的请求，所述一个或多个控制信道类型可具有相同或不同的报告要求。 
应注意，接入终端机可将其全部的控制信道消息传输至所述FLSS，无论所述控制信道消息应用于哪一个扇区或接入点。此外，所述接入终端机可将所述控制信道消息传输至所述控制信道消息的具体目标扇区。另外，可针对不同的扇区使用这些方法的组合。 
此外，在信道化系统中，例如，在那些其中带宽被划分成若干共同存在的载波的系统中(其中使用者通信可被约束在部分带宽或载波中)，所述接入终端机可仅在限于传送数据的载波中以及所指令的其他载波中传输控制信道。 
如本文中所使用，接入点可为用于与终端机进行通信的固定台，且还可称为基站、节点B、或某些其他术语，且包括其某些或全部功能。接入终端机还可称为使用者设备(UE)、无线通信装置、终端机、行动台或某些其他术语，且包括其某些或全部功能。 
本文所述传输技术还可用于各种无线通信系统，例如，CDMA系统、TDMA系统、FDMA系统、正交频分多址(OFDMA)系统、单载波FDMA(SC-DMA)系统等等。OFDMA系统利用正交频分多路复用(OFDM)，其是一种将系统总带宽分割成多(K)个正交副载波的调制技术。所述副载波也称为音调、频段等等。通过OFDM，可使用数据独立地调制每一副载波。SC-FDMA系统可利用：交错DMA(IFDMA)以在分布于系统带宽上的副载波上传输、本地化FDMA(LFDMA)以在毗邻副载波区块上传输、或增强FDMA(EFDMA)以在多个毗邻副载波区块上传输。一般来说，通过OFDM在频域中及通过SC-FDMA在时域中发送调制符号。 
系统100可针对正向及反向链路使用各种副载波结构。对于分布式副载波结构来说，总共K个副载波布置成S个非重叠集合，以使每一集合包含N个均匀分布在总共K个副载波上的副载波。每一集合中的连续副载波间隔S个副载波，其中K＝S·N。因此，集合s包含副载波s、S+s，其中 对于区块副载波结构来说，总共K个副载波布置成S个非重叠集合，以使每一集合包含N个连续副载波。因此，集合s包含副载波(s-1)·N+1至s·N，其中

大体来说，每一链路的副载波结构可包含任何数量的集合，且每一集合可包含任何数量的可以任何方式布置的副载波。在针对下文大多说明所假设的一个方面中，反向链路使用区块副载波结构。 
对于每一链路，系统100可支持单载波或多载波。在一个方面中，所述系统数支持的每一载波可使用多个(C)副载波。还可将每一载波分割成多个(P)子带。子带是所述系统带宽中的一个频率范围。在一个方面中，每一载波跨越大约5Hz，C＝512，P＝4，S＝32且N＝16。对于这个方面，单载波系统总共具有K＝512个布置成四个子带的副载波，且每一子带包括128个副载波。对于这个方面，单载波系统具有32个副 载波集合，且每一集合包括16个副载波。对于这个方面，具有四个载波的系统总共具有K＝2048个布置成16个子带的副载波。 
应注意，子带可为由数量不同于以上所述的副载波构成的段，其可总共跨越整个载波的一部分，且可在每一信道中的一个或多个子带之间具有不同数量的副载波。 
图2A显示可用于正向及反向链路的例示性超帧结构200。每一链路的传输时线被分割成若干超帧单元。每一超帧跨越一段可为固定或可变的特定时期。对于所述正向链路，每一超帧包括一个后跟有M个帧的前同步码，其中M＞1。帧可指传输时线内的时间间隔或在所述时间间隔期间发送的传输。所述超帧前同步码携载开销信息，所述开销信息可使终端机接收正向链路控制信道并随后接入所述系统。每一随后的帧可携载业务数据及/或控制信道消息。对于所述反向链路，每一超帧包括M个帧，其中所述第一帧可被扩充所述超帧前同步码在正向链路上的长度。所述反向链路上的超帧可与正向链路上的超帧大致时间对准。 
图2A显示正向链路及反向链路的特定超帧结构。一般来说，超帧可跨越任何时期且可包括任一数量的帧及其他字段。反向链路的超帧结构可相同或不同于正向链路的超帧结构。 
图2B显示反向链路的交织结构210。返回参照图2A，对于每一链路，可将每一超帧中的帧布置成若干个群组，其中每一群组包括Q个连续帧，其中Q＞1。以此方式对帧进行分组，每一链路可形成Q个交织。在图2B所示的一个方面中，交织1包括帧1、Q+1、2Q+1等等，交织2包括2、Q+2、2Q+2等等，且交织Q包括Q、2Q、3Q等等。所述Q个交织彼此偏移一个帧。如下所述，在针对下文大多说明所假设的一个方面中，Q＝6，形成六个交织并可使用其以交织的方式发送六个分组，每一交织中有一个分组。 
系统100可支持频分双工(FDD)及/或时分多路双工(TDD)。对于FDD来说，如图2A中所示，为正向及反向链路分配单独的频带，且可在两个链路上同时发送传输。对于TDD来说，正向及反向链路共享相同频带，且可在不同帧中发送两个链路的传输。例如，可为正向链路分配奇数编号的帧，而为反向链路分配偶数编号的帧。作为另一选择，也可使用其他的分配方式，例如，一个是另一个的倍数。 
在一个方面中，在反向链路上发送控制段。所述控制段携载用于反向链路的各种控制信道消息。在一个方面中，将所述控制段映射至每一控制帧中的固定时频区域。控制帧是在其中发送控制段的帧。在另一方面中，所述控制段以伪随机或确定性方式从一个控制帧跳跃至另一个控制帧以实现频率分集。 
图3A显示单载波的控制段300的方面。对于这个方面，Q＝6，且所述控制段是在一个交织上或每隔五个帧发送。对于这个方面，所述控制段跨越整个常规大小的帧。如图3A中所示，如果所述控制段在交织1上发送，则对于经扩充的反向链路帧1，可在对应于正向链路帧1的时间间隔中发送所述控制段。如果在交织2、3、4、5或6上发送所述控制段，则可针对所述交织中的每一帧在所述整个帧中发送所述控制段。 
图3B显示单载波的经扩充控制段310的方面。对于这个方面，Q＝6，且所述控制段在两个常规大小的帧中在一个交织上发送。对于图3B中所示的方面，在整个扩充的反向链路帧1、反向链路帧6及7、反向链路帧12及13等等中来发送所述控制段。也可在其他RF帧中发送其他交织的控制段。 
跨越图3A所示的整个帧或跨越图3B中所示的多个帧(而非跨越部分帧)来发送所述控制段中的控制信道消息可改善位于覆盖范围边缘处的终端机的链路预算。这些终端机通常具有发射功率的上限。较长的控制段允许这些终端机发射控制信道消息而在较长的时期内散布较多的能量，这可改善正确接收所述控制信道消息的可能性。大体来说，可跨越整个帧、跨越帧的一部分、跨越多个帧、跨越多个帧的若干部分等等来发送所述控制段。 
在一个方面中，所述控制段占据每一控制帧中的至少一个副载波。对于图3A中所示的方面，P＝4，且所述控制段是在每一控制帧中的四个副载波的至少一者上发送。在针对大多下文说明所假设的一个方面中，可以(例如)副载波为单元频率缩放所述控制段的大小。对于这个方面，所述控制段可跨越每一控制帧中的一个、两个或可能地更多个副载波。所述控制段的副载波可为相邻的或可散布在系统带宽上。在另一方面中，可对所述控制段的大小进行时间缩放或进行时频缩放二者。 
大体来说，如图3A左上角所示，可将控制段映射至覆盖F个副载波并跨越T个符号周期(F＞1且T＞1)的时频区域。所述控制段包括U个传输单元，其中U＝F·T。传输单元是一个符号周期中的一个副载波。为清楚起见，大多以下说明是关于其中控制段占据一个或多个副载波且跨越整个控制帧(反向链路帧除外)的方面。在一个方面中，K＝512，P＝4，且T＝8。对于这个方面，控制段(1)覆盖控制帧的8个符号周期中数量为128整数倍的副载波；且(2)包括数量为1024整数倍的传输单元，例如，1024、2048、3072或4096个传输单元。 
图3A还显示所述控制段的跳频。如图3A中所示，所述控制段可跳频跨越不同的控制帧中的频率。所述跳频可为伪随机或确定性的。 
图3A进一步显示用于业务信道的一个例示性跳频方案。业务信道是一种从发射机发送数据至接收机的装置，且还可称其为信道、物理信道、实体层信道、数据信道等等。可将每一业务信道映射成特定的时频区块序列，如图3A中所示，所述时频区块跳频跨越不同帧中的频率以实现频率分集。在一个方面中，时频区块对应于一个帧中的一个副载波集合。跳频(FH)图案指示用于每一帧中的每一业务信道的特定时频区块。图3A显示一个业务信道y的一个时频区块序列。可将其他业务信道映射成业务信道y的时频区块序列的垂直及原型移位版本。 
在一个方面中，业务信道的跳频可避免控制段。在另一方面中，业务信道的跳频相对于控制段是伪随机的。对于这个方面，可为每一控制帧中的控制段分配若干(例如，八个)副载波集合。然后，将与所述控制段抵触的每一业务信道映射成分配至控制段的副载波集合。对于这个方面，当发生抵触时，业务信道与控制段可交换副载波。 
图3C显示四个载波的跳频控制段320的一个方面。对于这个方面，给每一载波提供一个控制段实例。在一个方面中，每一载波的控制段实例携载所述载波的反向链路控制信道消息且与其他载波的控制段实例不相关。所述四个载波的四个控制段实例：(1)可具有相同或不同的大小；(2)可一起跳频或彼此独立地跳频；及(3)可在一个交织上(例如，每隔五个帧)发送。 
图3A及3B显示控制段的某些方面。在另一方面中，可在多个交织中发送所述控制段。在另一个方面中，可在其中可能发送控制段的每一帧中选择性地启用或禁用所述控制段。 
系统100可利用各种控制信道消息来支持正向链路及反向链路上的数据传输。所述控制信道消息通常携载少量的用于物理层的控制信道消息。用于每一链路的具体控制信道消息可取决于各种因素，例如，传输业务数据的方式、传输控制信道消息的方式、业务信道及控制信道消息的设计等等。 
在某些方面中，所述反向链路控制信道包括如下的一者或多者：信道质量指示信道(R-CQICH)、空间方向模式报告信道(R-BFCH)、段灵敏调度信道(R-SFCH)、导频信道(R-PICH)、请求信道(R-REQCH)及确认信道(R-ACKCH)。 
接入终端机可使用R-CQICH将不同扇区的正向链路信道质量(例如，经量化的CQI值)传输至接入网络、RLSS或其活动组中的任一其他所能传输到的扇区。R-SFCH是接入终端机可用来传输针对FLSS的副载波段所量测的正向链路信道质量的反馈信道。R-BFCH是接入终端机用来传输波束及附加CQI或完整CQI以启用SDMA、预编码、波束形成或其组合的反馈信道。R-PICH可为宽带导频信道。接入终端机可使用R-REQCH来请求资源。接入终端机可使用R-ACKCH来确认正向链路传输。 
在某些方面中，可指令接入终端机传输FLSS控制段上的如下至少一者：R-CQICH、R-BFCH，R-SFCH、R-PICH、R-REQCH及R-ACKCH。另外，可指令接入终端机以仅传输每一为非同步子组中成员的扇区的控制段上的R-CQICH。对于那些是FLSS或RLSS同步子组中成员的扇区，可为任一信道提供所述指令，然而，报告可受到是否产生足够量测结果的能力的约束。此外，在大多数方面中，向同步子组中成员的报告可局限于R-CQICH。

经由所述R-CQICH提供的信息可用于很多目的，其中包括(例如)：速率预测、正向链路功率控制、波束选择、预编码加权调节及以各种正向链路传输模式进行调度。另外，在某些方面中，当扇区并非为FLSS时，R-CQICH的信息可通过传输从其导频接收来的信道信息，从而指示越区切换至另一扇区的请求。在某些方面中，取决于CQI报告的类型，R-CQICH中所包含的信道信息可有所不同。取决于CQI报告模式，每一接入终端机可支持多种CQI报告格式。 
可基于从接入网络商定或另外由接入网络所指令的经指令报告模式来设定接入终端机的信道反馈报告模式。接入终端机的报告模式可为如下一者或某一其他模式：单代码字CQI报告模式(CQISCW)、多址字CQI报告模式(CQMCW)或SISO CQI报告模式(CQISISO)。 
此外，还包含其他的报告模式，例如，那些与具体传输类型(例如，SDMA、预编码、波束形成或其组合)有关的报告模式。在这类情况下，将使用与所述模式有关并然后报告CQICH(如果经指令)的控制信道的组合来报告这些模式。

在某些方面中，可发送R-SFCH及R-BFSCH消息来替代R-CQICH消息，或除了R-CQICH消息之外，还可发送R-SFCH及R-BFSCH消息。可如此做以促进接入终端机正在操作的传输模式，而仍能使所用开销最小化。此外，如先前所述，每一这些报告的报告频率可根据接入网络的指令而适当地变动。 
针对CQICH或SFCH所报告的CQI值可以是基于任何由于预编码、SDMA、波束形成或其任一组合的缘故而引起或由其所提供的增益而计算出的CQI。接入终端机可基于其当前正向链路传输模式、期望的传输模式或所指派的传输模式来选择用于计算所述CQI的因子。在某些情况下，可从CQI的计算中排出来自SDMA的任何增益。可对CQI进行计算(尽管并非需要)以实现在擦除率及错误率方面的目标性能。 
如果拟将或期望将SDMA用于正向链路传输，则提供所述BFCH。所述接入终端机通常仅将BFCH信道传输至反向链路服务扇区，但如果其能有效地从其活动组内的另一扇区确定广播导频，则其还可提供这个其他的扇区，尤其是在所述接入终端机正在请求越区切换或处于越区切换状态的情况下。 
在某些方面中，取决于报告的类型，R-SFCH中所包含的信道信息可有所不同。取决于报告模式，所述报告可有所不同。R-SFCH报告指示特定子带、段或其他副载波群组上的正向链路信道质量。正向链路信道质量可包括来自预编码、波束形成、STTD等的增益。然而，在某一个方面中，接入终端机可在R-SFCH报告中仅指示优选的子带、段或其他副载波群组，而不发送任何关于正向链路信道质量的信息。这可通过将CQI值设为0来完成。可使用这个特征来增加R-SFCH报告的性能，例如，改善R-SFCH报告的解码复杂性及性能。

                      的CQI值。然而，接入终端机可将这些位设为0。可

SubBandRank           指示所报告的SubBandlndex或其他索引的正向链路 
                      MMO SCW传输中MIMO层的期望数量。然而，AT 
                      可将这些位设为0以获得改善性能。可在AP与AT 
                      之间商定这个特征。 
此外，可将多个子带集合(其中每一集合跨越所述载波的重叠部分)存储在码本中，从而允许扫描多个范围的大小以便报告优选的段。 
在某些方面中，取决于报告的类型，R-BFCH中所包含的信道信息可有所不同。取决于所述报告模式，所述报告可有所不同。所述R-BFCH报告指示针对预编码及SDMA及SDMA CQI值偏移所将要使用的波束索引，以实现SDMA传输。然而，在某一个方面中，接入终端机可选择仅指示优选的波束索引，而不发送任何关于SDMACQI值偏移的信息。这可通过将SDMA CQI值偏移设为0来完成。可使用这个特征来增加R-BFCH报告的性能，例如，改善R-SFCH报告的解码复杂性及性能。在另一方面中，接入终端机可指示相对于R-SFCH报告上所发送CQI值的SDMA CQI值偏移。在另一方面中，接入终端机可指示相对于R-CQICH报告上所发送CQI值的SDMA CQI值偏移。在另一方面中，接入终端机可指示绝对SDMA CQI值，所述绝对SDMA CQI值并非相对于R-CQICH或R-SFCH中任一其他CQI值，或其并非为R-CQICH或R-SFCH中任一其他CQI值的偏移。 
以下显示BFCHBeamlndex报告的格式。

    Beamlndex     6
    SDMADeltaCQI     3
    Reserved     1
Beamlndex        所述Beamlndex字段指示所期望的波束

                 R-CQICH中CQI值的整数CQI偏移。可与所述接入网络对 
                 此进行商定。 
Reserved         这个位被设为0值。 
在上文所述中，虽然在这些情况下对偏移进行报告，但还可使用针对SDMA波束的全CQI报告。进一步，相同的报告可适用于预编码，其中所述波束索引可对应于码本输入。所述CQI或δ可对应于所述波束索引。 
所述接入点可以每接入终端机的方式对每一反向链路控制信道的传输周期性进行控制，以管理对专用于传输信道信息的资源的总体载荷。 
如论述，取决于为其调度、期望调度所述接入终端机或针对正向链路以另外方式所指令的传输类型，存在数种接入终端机所能反馈的信道信息。在一个操作模式中，接入终端机可发送R-BFCH来提供可用于自适应预编码及/或正向链路上SDMA的反馈。在另一模式中，接入终端机可发送R-SFCH来指示副载波的优选段。 
接入终端机可在既定反向链路帧中传输一个以上反向链路控制信道。例如，所述接入终端机可在同一反向链路帧中传输R-CQICH、R-SFCH及R-BFCH。 
所述接入终端机可在控制段中传输导频信道(PICH)。除上述某些或全部信道信息报告之外，还可使用这个导频序列，或可使用这个导频序列来替代上述某些或全部信道信息报告，以实现自适应传输，例如，反向链路优选副载波或段调度及TDD系统中的SDMA。
所有反向链路控制信道的可用性、其平均传输间隔及模式可在扇区或专用接入终端机的基础上变动。如果由于所述控制段被约束而导致这些信道中的一个不可用，则所述接入点可选择启用通过较高层消息的特定接入终端机信道的消息或所述数据段中的消息。 
在某些情况下，上述消息占据若干个调制符号。在专用于信道信息传输的正交资源的情况下，例如，需要通过使用不同的代码或OFDM符号，将所述符号的数量扩充导频符号的数量。最后，可在反向链路上复制这些符号以提供信道及干扰分集。 
上述格式为例示性，且可具有不同的位大小、格式、组合等等。此外，报告为CQI的值可为经量化的值或为原始值。 
对于每一反向链路帧，接入终端机可在RLSS控制段上的每一CQICH上同时发送至多一个CQICH报告。对于每一反向链路帧，接入终端机可在其活动组中的每一扇区上的每一CQICH上发送至多一个CQICH。然而，取决于接入终端机的资源及传输率，可使用向RLSS及活动组成员报告消息的其他频率。 
所述接入终端机确定哪些同步子组来发送CQICH。接入终端机可对具有不同定时的每一扇区应用不同的规则，因为其是从与活动组中的一个或多个其他扇区(其活动组中的其他扇区取决于反向链路控制信道的类型)不同的源来接收其定时，所以CQI值可指示与接入终端机正报告的传输类型有关的信息。如果正在使用量化，则所述接入终端机可报告最高的列表CQI值，以实现提早的分组中止及所期望的系统解码错误率。 
如果期望针对优选的副载波段或副载波调度所述接入终端机，则可遵循如下的报告结构。所述接入终端机仅将SFCH信道传输至反向链路服务扇区，但如果其可有效地从其活动组中的另一扇区中确定广播导频，则其还可将此提供至其他的扇区，尤其在所述接入终端机正在请求越区切换或处于越区切换状态的情况下。 
参照图4，其中图解说明多址无线通信系统中发射机及接收机的一个方面。在发射系统210中，将若干个数据流的业务数据从数据源412提供至发射(TX)数据处理器214。在一个方面中，每一数据流都通过各自的发射天线发射。TX数据处理器414基于针对彼数据流所选定的特定编码方案来格式化、编码及交错每一数据流的业务数据以提供经编码的数据。在某些方面中，TX数据处理器414基于所述符号所正发射至的使用者及正发射出所述符号的天线来对数据流的符号应用波束成形加权。在某些方面中，可基于接收系统450处产生且作为反馈提供至发射机系统410的本征波束向量来产生所述波束成形加权。此外，在经调度传输的情况下，TX数据处理器214可基于从使用者传输的秩信息来选择分组格式。 
可使用OFDM技术通过导频数据来多路复用每一数据流的编码数据。导频数据通常是以已知方式加以处理的已知数据图案并可在接收系统处用于估计信道响应。然 后，基于针对所述数据流选定的特定调制方案(例如，BPSK、QSPK、M-PSK或M-QAM)来调制每一数据流的经多路复用导频及经编码数据。可通过处理器430所执行或提供的指令来确定每一数据流的数据率、编码及调制。如上所述，在某些方面中，根据从使用者传输来的秩信息，一个或多个流的分组格式可有所不同。 
然后，将所有数据流的调制符号提供至TX MIMO处理器420，TX MIMO处理器420可进一步处理所述调制符号(例如，用于OFDM)。然后，TX MIMO处理器420将NT个调制符号流提供至NT个发射机(TMTR)422a至422t。在某些方面中，TX MIMO处理器420基于所述符号所正发射至的使用者及正从所述使用者信道响应信息发射所述符号的天线，将波束成形加权、固定或接入终端机专用或预编码的加权施加至所述数据流的符号。 
每一发射机422均接收并处理各自的符号流以提供一个或多个模拟信号，并进一步调节(例如，放大、滤波及上变频)所述模拟信号以提供适于在MIMO信道上传输的经调制信号。然后，分别从NT个天线424a至424t发射来自发射机422a至422t的NT个经调制信号。 
在接收系统450处，NR个天线452a至452r接收发射的经调制信号，且将从每一天线452接收的信号提供至各自的接收机(RCVR)454。每一接收机454均调节(例如，滤波、放大及下变频)各自接收的信号，使经调节的信号数字化以提供样本，并进一步处理所述样本以提供对应的“接收”符号流。 
然后，RX数据处理器460从NR个接收机454接收NR个符号流并基于特定接收机处理技术对所述经接收的符号流进行处理，以提供NT个“经检测”符号流。下文将进一步详细阐述RX数据处理器460所进行的处理。每一经检测符号流均包括若干符号，所述符号是针对对应数据流所发射调制符号的估计值。RX数据处理器460然后解调、解交错及解码每一所检测的符号流，以恢复数据流的业务数据。RX数据处理器260所进行的处理与发射系统410处的TX MIMO处理器420及TX数据处理器414所实施的处理互补。 
可使用RX处理器460所产生的信道响应估计以实施接收机处的空间/时间处理，调节功率水平，改变调制速率或方案及/或实施其他动作。RX处理器460可进一步估计经检测信号流的信噪和干扰比(SNR)及可能地其他的信道特性，且将这些量提供至处理器470。RX数据处理器460或处理器470可进一步获得所述系统“操作”SNR的估计。然后，处理器470提供经估计的信道信息(CSI)，其可包括关于通信链路及/或所接收数据流的各种信息。例如，所述CSI可仅包括操作SNR。CQI的类型提供(例如)CQICH(SISO、SCW及MCW)、BFCH及或SFCH是基于当前调度的接入终端机、指令或期望的传输模式来确定。然后，TX数据处理器478(其从数据源476接收若干数据流的业务数据)对所述CSI进行处理，调制解调器480对其进行调制，发射机454a至454r对其进行调节，并将其发回至发射机系统410。 
在发射系统410处，天线424接收来自接收系统250的经调制信号，接收机422对其进行调节，解调器440对其进行解调制，且RX数据处理器442对其进行处理，以恢复由接收系统所报告的CSI。然后，将所报告的CQI提供至处理器430并使用其来(1)确定拟针对所述数据流使用的数据率及编码和调制方案及(2)为TX数据处理器414及TX MIMO处理器420产生各种控制信号。 
在所述接收机处，可使用各种处理技术来处理NR个接收的信号以检测NT个传输的符号流。可将这些接收机处理技术分组为两大类：(i)空间及空间-时间接收机处理技术，其还被称为均衡技术；及(ii)“连续清零/均衡及干扰取消”接收机处理技术，其还被称为“连续干扰取消”或“连续取消”接收机处理技术。 
可将NT个传输及NR个接收天线所形成的MEMO信道分解成NS个独立的信道，其中Ns＜mm{NT，NR}。还可将所述Ns个独立信道的每一者称为MBVIO信道的空间子信道(或传输信道)且对应于一个维度。 
对于满秩MEMO信道，其中Ns＝NT＜NR，可从NT个发射天线的每一者发射独立的数据流。所发射的数据流可经历不同的信道状态(例如，不同的衰落及多路径效应)，且对于既定量的发射功率，其可实现不同的信噪和干扰比(SNR)。此外，在那些于接收机处使用连续干扰取消处理以恢复所发射数据流的情况下，则然后可取决于所述数据流所恢复的具体次序实现所述数据流的不同SNR。因此，取决于其所实现的SNR，不同的数据流可支持不同的数据率。由于所述信道状态通常会随时间变化，所以每一数据流所支持的数据率也回随着时间而变化。 
所述MMO设计可具有两种操作模式：单代码字(SCW)及多代码字(MCW)。在MCW模式中，所述发射机可独立地且可能以不同的速率来编码每一空间层上所传输的数据。所述接收机使用工作如下的连续干扰取消(SIC)算法：解码第一层，并然后在重新编码之后从所接收的信号中减去其组分并使所编码的第一层乘以“经估计的信道”；然后解码第二层等等。这种“剥洋葱”的方法意味着每一连续解码的层可看见增加的SNR，且因此可支持较高的速率。在不存在错误传播的情况下，具有SIC的MCW设计可基于信道状态实现最大的系统传输容量。 
在SCW模式设计中，所述发射机以“相等的数据率”来编码每一空间层上所传输的数据。所述接收机可针对每一音调使用低复杂性线性接收机(例如，最小均方方案或零频率(ZF)接收机)或非线性接收机(例如，QRM)。这允许所述接收机的信道估计报告仅关于所述“最佳”的层及用于提供所述信息的减少传输开销。 
虽然图4及相关联的论述涉及MEVIO系统，但其他多输入单输出及单输出多输入(SEVIO)系统也可使用图4的结构及参照本文图1、5及6所论述的结构、方法及系统。 
参照图5，其中图解说明确定所提供反馈类型的方法的方面。确定为其正提供反馈的可应用扇区(方块600)。如果所述扇区是非服务扇区，则提供其中一个CQICHCTRL(方块604)。如果所述扇区是服务扇区，则可传输所有的CQI报告(方块602)。 
如果所述扇区是服务扇区，则所述接入终端机确定所述报告的类型(方块602)。这可基于来自FLSS或其他扇区的指令。然后，根据所述报告类型来提供所述反馈(例如，报告模式消息)。所述报告的频率是根据从FLSS或其他扇区接收的可随时间改变的指令。 
参照图6，其中图解说明确定所提供CQI报告的另一方法的方面。确定所述报告模式。可使用来自活动组的FLSS或其他成员且与所述活动组有关的指派消息来信令所述报告模式。如先前所述，所述报告模式可为SISO模式、MMO SCW模式及MIMOMCW模式。针对SDMA、预编码、波束成型及其他传输类型可使用另外的报告模式。 
在SISO模式中，提供控制信道CQI(例如，CQICHCTRL)类型的反馈(方块702)。在MIMO-SCW模式中，提供控制信道CQICHCTRL及CQICHSCW反馈(方块704)。以上显示并讨论了针对MIMO SCW所提供的MIMO反馈的实例。在MIMOMCW模式中，提供控制信道CQICHCTRL及CQICHMCW反馈(方块706)。以上显示并论述了针对MIMO SCW所提供的MIMO反馈的实例。
