Description
技术领域
本发明涉及MIMO通信系统。
本申请要求2011年4月29日提交的美国临时专利申请序列号61/481,024的优先权,并且通过引用将其整体并入在此。
背景技术
多输入多输出(MIMO)技术的使用已经引起在无线通信系统中使用的增加的注意力,因为在不需要附加带宽或传输功率的情况下MIMO提供了数据吞吐量和链路范围的显著增加。由MIMO技术提供的增加的性能源自较高的频谱效率(每秒每带宽赫兹传输较大数目的比特),以及较大的链路可靠性或多样性。因此,MIMO形成包括3GPP长期演进(参见3GPP TS 36.213,技术规范版本10章节,2011年6月,第三代合作伙伴计划)、IEEE 802.11n(WiFi)、802.16(WiMAX)和HSPA+的现代无线通信标准的一个重要部分。
一个关注的区域是提供鲁棒秩自适应(rank adaptation)的能力。秩自适应指代根据改变信道状况的秩的动态控制。可以通过诸如MIMO系统中的各天线之间的衰落相关性和信号干扰噪声比(SINR)之类的参数来确定信道状况。利用空间复用,基站(或eNodeB或eNB)可以使用同一频率将多个数据流或层发送到下行链路传输中的UE。这样的层或流的数目被定义为秩。UE可以定期测量信道并且将秩的推荐发送给eNB。在不同的方案中可以定期或不定期地发送所谓的秩指示符(RI)。因为报告给eNB的RI会随着时间改变,所以eNB可以基于从UE接收到的改变的RI来调整在下行链路传输中使用的数据流的数目。然而,若干个因素会使得该过程不如理想情况。在一些情况中,可能影响信道质量的干扰水平可以在两个连续RI报告之间显著改变,在这种情况下,eNB没有机会调整秩,即使最后报告的秩因为改变的干扰状况而可能不适当。在其他情况中,当使用所谓的宽带秩时,所报告的秩指示符可以基于整个传输频带(宽带),其可以包括用于UE和eNB之间的通信的一组频率子带。在许多情况下,干扰状况可能在宽带内的不同子带之间显著不同,因此危及eNB对于单独的子带而报告的宽带RI的有效性。
关于多用户MIMO(MU-MIMO)的使用的另一问题已经出现,在其中UE可能以过高的秩传输预编码矩阵指示符/信道质量指示符(PMI/CQI)报告以便有效地支持最高效MU-MIMO调度:在MU-MIMO中,eNB可以调度多个不同UE通过同一传输频带进行传输。作为UE可以仅评估其自己的链路性能且一般不知道MU-MIMO方案中的任何协同调度候选的事实的结果,会发生过分高的秩的报告。因此,即使可以通过高秩单用户MIMO(SU-MIMO传输)来使UE的链路性能最大化,但是在使用较低秩传输来协同调度UE和第二终端(对UE来说未知)的情况下系统性能较高可能很好。所报告的包括PMI/CQI/RI的信息因此可能与MU-MIMO分配匹配不佳。特别地,该终端可能通常选择对MU-MIMO调度来说过高传输秩,从而难以有益。
在其他情况中,在eNB优选在SU-MIMO传输下进行操作的情况下,UE可以报告秩为1,即使eNB可能优选UE报告适应的值,而不是总是报告秩为1。
就这些和其他考虑而言,已经需要本改进。
发明内容
根据本发明的一个方面,提供了一种用于在无线通信中执行秩自适应的装置,包括:发射器,其被布置成将传输频带内信道的信道状态报告无线传输到基站;处理器;秩自适应(RA)模块,其在所述处理器上可操作用来指示所述发射器发送以下各项:大量子带信道质量指示符(CQI)报告,每个子带CQI报告包括所述传输频带的各自子带的测量结果;以及大量秩指示符(RI)报告,RI报告伴随每个子带CQI报告;以及数字显示器,其被布置成显示经由基站传输到所述装置的信息。

具体实施方式
各种实施例可以总体上指向采用使用多输入多输出(MIMO)无线通信的无线通信的系统。一些实施例可以特别指向用于秩自适应的装置、架构和方法。
各种实施例可以包括一个或多个元件。元件可以包括被布置成执行某些操作的任何结构。尽管可以以示例的方式利用某一布置中的有限数目的元件来描述一个实施例,但是针对给定实施方式按照期望该实施例可以包括替换布置中的较多或较少的元件。值得注意的是,对“一个实施例”或“实施例”的任何参考意指结合实施例所述的特定特征、结构或特性被包括在至少一个实施例中。在说明书中的各种地方出现的短语“在一个实施例中”不必都指代同一实施例。
在一个实施例中,一种方法包括通过无线传输频带测量大量子带信道质量指示符(CQI),每一个子带CQI与传输频带的各自频率子带相对应;在第一实例处传输所述大量子带CQI中的一个或多个子带CQI;选择用于传输频带的一个或多个秩指示符(RI);以及在第一实例处传输与所选一个或多个RI相对应的一个或多个RI报告。
该方法还可以包括定期地传输每一个子带CQI报告。
可替换地,该方法还可以包括传输大量子带PMI报告,每一个子带PMI报告与各自子带CQI报告相对应。
该方法还可以包括传输子带RI报告和各自子带CQI报告,每个子带RI报告和各自子带CQI报告与传输频带的同一子带相对应。
该方法可以附加地包括不定期地传输子带CQI报告,在第一实施方式中该方法可以包括从传输频带内选择大量带部分秩指示符,每个带部分RI基于大量邻接子带的测量,以及利用子带CQI报告传输每一个都导出自所选带部分RI的大量带部分RI报告;而在第二实施方式中,该方法可以包括从传输频带内选择大量子带秩指示符,每个子带秩指示符基于传输频带的各自频率子带的测量,以及利用子带CQI报告传输每一个都包含各自子带RI的大量子带RI报告。
图1图示通信系统10的一个实施例的框图,所述通信系统10可以包括这里公开的信道估计架构的实施例。如图1中所示,通信系统10可以包括通过链路18-m与多个节点14-n进行通信的网络12,其中m和m可以表示任何正整数。在各种实施例中,节点14-n可以被实施为各种类型的无线设备。无线设备的示例可以包括但不限于站、订户站、基站、无线接入点(AP)、无线客户端设备、无线站(STA)、膝上型计算机、超级膝上型计算机、便携式计算机、个人计算机(PC)、笔记本PC、手持计算机、个人数字助理(PDA)、蜂窝电话、蜂窝电话/PDA组合、智能电话、寻呼机、消息收发设备、媒体播放器、数字音乐播放器、机顶盒(STB)、器具、工作站、用户终端、移动单元、消费电子品、电视、数字电视、高清电视、电视接收器、高清电视接收器等等。
在一些实施例中,通信系统700中的大量设备可以采用多输入和多输出(MIMO)通信,在该多输入和多输出(MIMO)通信中接收器和发射器二者都采用多个天线。通信系统的一些实施例以无线电技术(诸如IEEE 802.16(WiMAX)、IEEE 802-20、演进UTRA(E-UTRA)等等)来实施。IEEE 802.16m是IEEE.802.16e的演进并且提供与基于IEEE 802.16的系统的向后兼容。UTRA是通用移动电信系统(UMTS)的一部分。第三代合作伙伴计划(3GPP)长期演进(LTE)是使用E-UTRA的演进UMTS(E-UMTS)的一部分。先进LTE(LTE-A)是3GPP LTE的演进。
为了清楚起见,下面的描述可以集中于与LTE-A有关的实施例。然而,其他实施例可以采用其他标准,如上文所指出的那样。
图2a和2b描绘根据各种实施例的UE 100的操作。UE 100可以被调度成以SU-MIMO模式(图2a)或MU-MIMO模式(图2b)来操作。在图2a中描绘的SU-MIMO模式的一个实施方式中,eNB 102可以传输来自两个天线114、116中的每一个的下行链路信号106。如图2a中所示,每个天线114、116将信号传输到两个UE天线110、112中的每一个。然而,在一些实施例中,UE 100和eNB每一个都可以具有附加天线。
UE 100还可以以MU-MIMO模式操作,如图2b中所描绘的那样。可以以常规模式操作的单独终端(UE 104)和UE 100中的每一个被描绘为传输在上行链路通信期间形成由eNB 102接收到的上行链路信号122的一部分的各自的信号124和126。在所描绘的上行链路通信中,从天线112发送信号124且可以在eNB 102的天线114和116处接收到信号124。在各种实施例中可以通过物理上行链路控制信道(PUCCH)来提供信号124。类似地,附加的UE设备104传输来自天线118的信号126,也可以在eNB 102的天线114和116处接收到该信号126。然而,MU-MIMO的其他配置是可能的。
在各种实施例中,从UE 100发送的上行链路信号124可以特别包括诸如RI、PMI和CQI之类的控制信号。在不同实施例中可以以规则的定期方式或不定期方式报告由UE 100传输的控制信号的至少一些。在各种实施例中,UE被布置成修改与eNB的通信以便提供鲁棒的秩自适应。例如,UE 100可以在干扰随着时间显著变化的环境中操作。干扰可以以迅速的不可预期方式发生。因此,期望以及时方式改变报告给eNB的秩以解释会更改优选秩的大量干扰变化。根据各种标准,用于报告控制信号(其可以包括信道状态信息(CSI),诸如PMI/CQI/RI报告(在下文中也被称为“信道状态报告”))的框架会限制报告RI信息的灵活性。在一些实施例中,UE可以提供以更有效方式更新RI的用于信道状态报告的更有效框架。UE 100可以包括例如秩自适应(RA)模块108,其可以执行各种功能,诸如如下文所详述的确定要被报告的秩信息以及调度秩指示符报告。特别地,RA模块105可以实施在图3至10中描绘且下面讨论的过程和架构。
图3a和3b描绘根据一些实施例的用于信道状态包括的增强框架的操作。在图3a中,基于在LTE版本10中规定的时序来图示用于提供信道状态报告的框架。特别地,所示的场景描绘如针对PUCCH-2子带报告模式所规定的CQI/PMI/ RI时序。上行链路通信被分成包括传输频带的九个邻接子带154。子带154可以被分成三个带部分156。在时间t0处,传输与表示传输频带的频率范围FR的宽带信道状况一致的宽带(W2)秩指示符报告150和CQI /PMI报告152(为了清楚起见没有在标签中明确示出“PMI”)。当RI报告150被传输到eNB时,可以根据所报告的RI来更新下行链路秩。例如,在接收到RI报告150之后,可以将秩从“2”重新调度到“4”。
根据PUUCH-2-1子带报告模式,在与子带CQI /PMI测量结果的报告时段相对应的随后时间段内传输一系列子带CQI /PMI报告158a至158f。每个CQI /PMI报告158a至f与子带SB0至SB8的不同子带相对应,并且在子带之间彼此不同的时间报告该每个CQI /PMI报告158a至f。如图3a中所描绘的,在时间t1处,干扰事件I发生。例如,在W2的频率范围内出现可能强的新干扰。然而,为了遵守由LTE2-1子带报告模式标准所规定的报告过程,可以不传输随后的RI报告直到至少时间t2为止。该时间t2与要被传输的所有CQI /PMI子带报告的当前报告时段的结束相对应。因此,在t1和t2之间的整个时间段160期间,秩可以保持在“4”,尽管干扰状况可能保证改变,诸如到秩为“1”的改变。因此,在该时段160期间通信被降级。
在图3b中所描绘的实施例中,例如使用提供更及时RI自适应的RA模块105来修改信道状态报告框架(架构)。在该实施例中,以与CQI /PMI子带报告158a至f相类似的时序来布置一系列子带报告168a至168f。然而,RI报告170a至170-f被包括在每个各自的子带报告168a至f中。因此,在时间t3处,提供RI报告170b,在一个示例中该RI报告170b可以将秩更新为“4”。在干扰状况的改变在时间t1处发生的场景中,图3b的实施例的信道状态报告架构提供以更及时方式适应秩的能力。如所图示,可以在时间t4处立即提供随后的RI报告170c。基于反映在时间t3处发生的干扰变化并且可以持续的时间t4处的信道测量,UE可以在RI报告170c中推荐秩为“1”。因此,在其中操作秩(4)不适合于本信道状况的时间t1和t4之间的持续时间180被减小为比使用图3a的常规框架的持续时间160更小得多的持续时间180。
在一些实施例中,使用图3b中总体描绘的架构,在子带CQI /PMI报告之前的RI报告可以被设计为宽带秩指示符,而在其他实施例中,RI报告可以是仅可适合于子带CQI /PMI报告所扫描的给定带部分的子带RI。
在不定期提供CSI的其他实施例中,可以使RI的报告适应于CSI报告的频带结构定制。例如,可以以不定期方式通过物理上行链路共享信道(PUSCH)提供CSI。图4描绘可以用于不定期报告PMI/CQI/RI信息的CSI报告结构204的一个实施例。该报告结构可以被看作对PUSCH 3-2报告模式的修改。如所图示,报告结构204包括与频带200的频率子带SB0至SB9相对应的一系列CSI子带。如所图示,为每个子带SB0至SB9提供包括SB PMI0至 SB PMI8的子带报告206和包括SB CQI0至SB CQI8的CQI子带报告210的对应PMI集合。另外,提供每个都跨越三个邻接子带的三个RI报告(带部分RI)208a至208c的集合。这些RI报告相应地提供跨越由三个邻接子带在每种情况下限定的频率范围的RI。
可替换地,可以为频带的每个子带提供不定期RI报告。图5描绘包括九个单独的子带RI报告214a至214i的CSI报告结构212的一个实施例,该九个单独的子带RI报告214a至214i中的每一个与子带频率SB0至SB8相对应。在各自图4和图5的实施例中示出的带部分或子带秩指示符可以通过提供覆盖宽带内的更窄频率范围且因此更可能报告准确反映给定频率范围内的信道状况的秩的不定期RI报告来促进更准确的秩自适应,所述给定频率范围内的信道状况可能与同一传输频带内的其他频率范围中的那些状况显著不同。
在另一些实施例中,UE可以被布置成修改用于选择要被报告给eNB的PMI的搜索过程和用于确定报告的最佳秩指示符的过程。图6描绘包括处理器220、存储器222和发射器224的UE 100的实施例。天线110、112二者用作发射器(Tx)和接收器(Rx)天线。存储器222可以包括(多个)代码本226,其可以包括多个秩,例如8个秩。在一些实施例中,代码本226可以总体上被布置成针对LTE版本10而提供。特别地,代码本226可以具有嵌套结构,以使得对于给定秩的每个预编码器矩阵,在比给定秩更小的秩的所有代码本中存在至少一个对应列。
在一个实施例中,UE 100可以根据下面的过程执行秩自适应。UE 100可以执行信道测量以确定下述各种参数。处理器220可以使用根据下式的代码本226来执行PMI搜索:
其中Cr表示具有秩r的代码本,R是所测的给定频带的信道协方差矩阵,且ir表示对于秩r的最佳PMI。在根据等式(1)选择对于给定秩r的最佳PMI之后,UE可以选择报告给基站的最佳秩rbest。
在一个实施例中,根据下式来确定rbest:
其中H是感兴趣的信道矩阵且SINR是每Rx天线的信号噪声和干扰比。因此,在确定SINR之后,UE可以计算rbest且向eNB报告最佳秩和对于最佳秩的最佳PMI二者。以该方式,在单个用户MIMO操作中,可以在执行秩自适应时使SU-MIMO的容量最大化。
在另一些实施例中,UE可以执行秩自适应和PMI选择以增强在可能发生单用户MIMO和多用户MIMO操作之间的动态切换的环境中的MIMO操作。这可以对为秩1 PMI搜索设计代码本的当前过程进行改进。
如已知的那样,基于代码本的预编码通常包括在通信会话之前将代码本(即预编码矩阵集合)存储在发射器和接收器二者处。接收器然后可以遵循规定的规则,以根据当前信道状态选择最优预编码矩阵,且将所选矩阵的PMI返回给发射器。然而,诸如LTE版本8代码本的先前代码本可能不会在MU-MIMO场景中或对于SU-MIMO和MU-MIMO之间的动态切换最优地执行。
特别地,在当前代码本过程中,需要最佳秩2 PMI不等于最佳秩1 PMI。因此,针对报告高秩的秩自适应的当前过程不会导致最优PMI。作为一个示例,当UE执行秩自适应且选择用于报告的秩2时,UE需要报告一个预编码器和两个信道质量指示符(CQI),每一个都与秩2预编码器的一个列相关。在具有嵌套结构的代码本(诸如由LTE版本8指定的4 Tx代码本)中,具有与秩1的PMI值相同的PMI值的所有秩2预编码器将包含与秩2预编码器中的第一列相对应的秩1预编码器。尽管秩1预编码器与秩2预编码器的一部分相一致,但是这不能保证对矩阵索引进行预编码的最佳秩2将总是等于对矩阵索引进行预编码的最佳秩1。
为了图示该问题,图7a和7b进一步给出如由LTE版本8代码本规定的PMI分布的比较。特别地,图7a示出秩1 PMI分布240,其中y轴指示对于该分布的给定点的相对频率。x轴表示代码本的不同预编码矩阵索引。如图7a中所描绘,分布240相对不均匀。在零到七的PMI值之间,对于除了“2”之外的每个索引,概率是约10%到15%。结果,当UE执行秩1代码本中的PMI搜索,存在将选择主特征向量的大概率。
与此相比,图7b给出基于LTE版本8代码本的秩2 PMI分布250。在该情况下,PMI分布250比秩1 PMI分布240更不均匀得多。特别地,仅PMI“1”、“3”和“8”具有非常大的概率,而所有其他PMI具有5%或更小的概率。因此,当UE执行秩2中的PMI搜索时,存在两个非主特征向量具有比 与另一个响亮一起正交于主特征向量的主特征向量更高的容量的合理概率。因此,当eNB接收秩2 PMI报告且进行从秩2预编码器提取主特征向量时,eNB可能在较高容量非主特征向量的情况下不能找到主特征向量。因此,秩1和秩2 RI之间的秩自适应可能不会恰当地发生。
根据另一些实施例,UE可以被布置成确保秩2预编码器总是包含主特征向量。在一个实施方式中,这可以在UE通过确定仅假设秩1的PMI来执行秩自适应时完成。这是合理的方法,因为如上所讨论,本质上具有与秩1的PMI值相同的PMI值的所有秩2预编码器包含对应的秩1预编码器。然后可以基于同一PMI的使用来确定RI。
其中C0是具有秩1的代码本。
在各种实施例中,对于比秩1更高的秩的最佳PMI可以被假设成与秩1 PMI相同,以便根据下式来利用代码本(诸如LTE版本8)的嵌套结构:
(4)。
UE然后可以根据在上面的等式(2)中阐述的过程集来执行秩自适应。因此,UE确保最佳较高秩预编码器总是包含可用于MU-MIMO传输的主特征向量。
在各种实施例中,可以对UE和基站之间的不同传输模式实施在等式(3)和(4)中阐述的上述过程。例如,该过程可以被应用于支持报告CQI/PMI/RI(CSI)的所有那些传输模式或其子集。在一个实施方式中,可以通过实施用于报告CSI的标准的改变来修改LTE RI报告过程。最近LTE标准(3GPP TS 36.213 V10.2.0,6-2011)规定UE可以采用来报告上行链路控制信道(PUUCH)上的CSI的九个传输模式,包括传输模式4、8和9。用于限定定期CSI报告的章节(章节7.2.2)的文本当前读取:对于传输模式4、8和9,以最后报告的定期RI为条件来计算PMI和CQI。对于其他传输模式,以传输秩1为条件来计算它们。
在一个实施例中,可以如修订文本中所规定的那些修改该过程:对于传输模式4、8和9, 以秩1为条件来计算PMI且以最后报告的定期RI为条件来计算CQI。对于其他传输模式,以传输秩1为条件来计算它们。 所报告的PMI和CQI以最后报告的RI为条件。
根据所公开的实施例,可以为SU-MIMO或MU-MIMO操作修改和优化PMI搜索和秩自适应过程。在替换实施例中,eNB可以采用传播或单播来向UE通知其对SU-MIMO或MU-MIMO传输的偏好。eNB可以因为业务状况的改变来动态改变其偏好。作为响应,UE可以动态更改在有利于SU-MIMO的一种方法和有利于MU-MIMO的一种方法之间采用的秩自适应方法。特别地,UE可以选择采用最优PMI搜索或秩自适应过程,包括上面关于等式(1)至(4)所论述的那些过程。UE可以使选择基于被认为与由eNB指示的传输偏好的最佳匹配的过程。在一些实施例中,为了使开销最小化,信令可以包括小至一个比特。
这里包括的是代表用于执行所公开的通信架构的新颖方面的示例性方法的流程图集合。然而,为了解释的简单性,在这里例如以流程图或流程示图的形式示出的一个或多个方法被示出和描述为一系列动作,将理解且认识到该方法不受动作顺序的限制,因为根据与其相关的方法,一些动作可以以不同的顺序发生和/或与不同于这里所示和所描述的其他动作同时发生。例如,本领域技术人员将会理解且认识到,方法将被可替换地表示为一系列相关状态或事件,诸如状态图。此外,不是方法中图示的所有动作都需要用于新颖的实施方式。
图8描绘根据本实施例的逻辑流程800。在框802处,在第一实例处通过传输频带的第一频率子带来传输第一信道质量指示符。在各种实施例中,还可以在框802或随后的框期间传输预编码矩阵索引。在框804处,在第一实例处通过该第一频率子带来传输第一秩指示符报告。在框806处,在第二实例处通过第二、不同频率子带来传输第二信道质量指示符。该第二频率子带可以与第一频率子带邻接或不邻接。第一和第二频率子带可以属于在UE和基站之间的上行链路中使用的同一传输频带。在框808处,在第二实例处在第二频率子带中传输第二秩指示符报告。在各种实施例中,可以在其他实例处在其他子带中一起传输附加CQI和RI报告。以这种方式,通过给定传输子带报告CQI信息的每个实例必需报告在每个报告实例之间适配的秩指示符。秩指示符可以与宽带秩指示符相对应或者可以是仅可适合于子带CQI /PMI报告所扫描的给定带部分的子带RI。
图9描绘与本实施例一致的另一逻辑流程900。在框902处,在第一实例处传输跨越第一频率范围的子带PMI的第一集合。在框904处,在第一实例处传输跨越第一频率范围的第一带部分秩指示符。在框906处,在第一实例处传输在第二频率范围上的第二子带PMI。在框908处,在第二实例处传输跨越第二频率范围的第二带部分秩指示符。在各种实施例中,可以在附加的第二、第三、第四实例等等处重复框902至908中的过程。在一些实施例中,第一和第二带部分秩指示符中的每一个可以跨越比对应第一和第二频率范围更大的频率范围,以使得由每个带部分秩指示符跨越的频率范围可以覆盖与多个PMI相对应的多个频率子带。
图10a描绘与另一些实施例一致的另一逻辑流程1000。在框1002处,根据上面阐述的等式(1)来确定最佳PMI 。可以针对多个秩r来确定值ir。在框1004处,根据上面阐述的等式(2)来确定向基站报告的最佳秩。在框1006处,基于和的确定来向基站报告最佳秩和对于最佳秩的最佳PMI。
图10b描绘与其他实施例一致的另一逻辑流程1020。在框1022处,根据上面阐述的等式(3)来确定最佳秩1 PMI 。在框1024处,将最佳PMI 设置成与最佳秩1 PMI 相同。在框1026处,执行秩自适应以确定根据等式(2)确定的用于向基站报告的最佳秩。通过采用逻辑流程1020,当以SU-MIMO模式进行操作时,UE可以经历性能的稍稍减少。然而,与SU-MIMO中的显著减少相比,逻辑流程1020可以仍提供MU-MIMO性能的净改进。
图10c描绘与其他实施例一致的另一逻辑流程1040。在框1042处,从基站接收指示MIMO偏好的消息。在框1044处,选择秩自适应/PMI选择过程的组合以便与MIMO偏好相匹配。在框1046处,实施所选的秩自适应/PMI选择过程并将适当的PMI/RI报告给基站。在各种实施例中,秩自适应和PMI选择的实施遵循关于等式(1)至(4)所讨论且在图7a至10b中描绘的实施例的任何适当组合。
