Description
优先权要求
本申请要求享有于2012年9月27日递交的、美国专利申请序列No.13/629,546的优先权的利益,该美国专利申请要求享有于2012年3月16日递交的、美国临时专利申请序列No.61/612,188的优先权的利益,这两个专利申请的每一个的公开内容以引用方式全部内容并入本文。
背景技术
作为第三代合作伙伴计划(3GPP)发布的LTE规范的版本10的部分的LTE-高级(长期演进-高级或LTE-A)的主要特征增强了对多用户MIMO(多输入多输出)的支持,在多用户MIMO中使用空间多路复用来提供在基站(在LTE系统中称为演进节点B或eNB)和多个终端(其中在LTE系统中终端称为用户设备或UE)之间的单独的下行链路和上行链路通信路径。随着在多用户MIMO操作的每个子帧内调度更多的UE,对于物理下行链路控制信道(PDCCH)资源为物理上行链路控制信道(PUCCH)资源提供调度的需求增长。LTE规范的版本8/9/10中PDCCH的设计提供了三种OFDM(正交分频多路复用)符号的最大PDCCH尺寸,这不足以满足该增长的需求。因此,在LTE规范的版本11中,将新的PDCCH设计,称为增强型PDCCH(ePDCCH),引入PDSCH(物理下行链路共享信道)区域中。PDCCH的结构基于所谓的控制信道元件(CCE),而ePDCCH利用基于物理资源块(PRB)的设计来增加容量且增强型对异质网络方案中的小区间干扰协调(ICIC)的支持。用于执行小区间干扰协调(ICIC)的版本8/9/10 PDCCH设计的局限性源自于如下事实:由于PDCCH交错,在PDCCH中用于下行链路控制信息(DCI)格式的传输的CCE以不规则形式分布在整个带宽上。另一方面,将ePDCCH置于具有基于PRB方案的PDSCH区域中允许ePDCCH分布在带宽上从而更佳地支持频域ICIC。
然而,基于PRB的ePDCCH的使用不能以与基于CCE的PDCCH同样的方式使用而动态地分配用于应答下行链路数据发送的上行链路资源。这是本公开所关注的。
附图说明
图1示出了依照一些实施例的UE和eNB。
图2示出了依照一些实施例的ePDCCH中的增强型控制信道元件的资源元件映射。
图3至图7示出了依照一些实施例的用于映射从检测到的ePDCCH中得到的PUCCH资源的示例方案。
具体实施方式
下面的说明书和附图充分地阐述了具体的实施例以使本领域技术人员能够实践它们。其它的实施例可以包含结构的、逻辑的、电的、工艺的以及其它的变化。一些实施例的部分和特征可以包含或替换成其它实施例的那些部分或特征。在权利要求书中阐述的实施例包含了那些权利要求的所有可用的等同实施例。
LTE使用前向纠错编码和ARQ(自动重复请求)的组合,称为混合ARQ。混合ARQ使用前向纠错码来校正一些错误。当检测到未经校正的错误时,丢弃受破坏的发送,并且接收器请求重新发送。如在本文中所使用的术语,混合ARQ应答可以是否定应答(NACK),表明已经出现发送错误并且请求重新发送,或者可以是肯定应答(ACK),表明正确地接收到发送。
当eNB将数据发送到UE时,UE要求eNB分配上行链路资源,从而以混合ARQ应答进行回应。此处所描述的是ePDCCH配置和技术,通过这种配置和技术,在下行链路资源的分配经由ePDCCH进行的情况下,这种上行链路资源可以动态地分配给UE。
LTE空中接口
图1示出了UE 100和eNB 150的实例。UE和eNB分别包含了处理电路110和160。UE中的处理电路110与各自与多个天线130中的一个连接的多个RF收发器120接口连接。eNB中的处理电路160与各自与多个天线180中的一个连接的多个RF收发器170接口连接。图示的部件旨在呈现用于提供LTE空中接口且执行如本文所描述的处理功能的任何类型的硬件/软件配置。
LTE空中接口也称为无线电访问网络(RAN),其具有可基本上描述如下的协议体系结构。最上层是分组数据压缩协议(PDCP)层,其发送和接收IP(互联网协议)分组。PDCP层经由IP分组所映射到的无线电载体与RLC层通信。在介质访问控制(MAC)层,与上方的RLC层的连接通过逻辑信道,并且与下方的物理层的连接通过传输信道。MAC层处理逻辑信道之间的多路复用/解多路复用、混合ARQ操作以及调度,后者仅在用于上行链路和下行链路的eNodeB处执行。传输信道中的数据被组织成传输块,在UE和eNB处相对于传输块执行混合ARQ功能。用于数据发送的主传输信道、上行链路共享信道(UL-SCH)和下行链路共享信道(DL-SCH)分别映射到在物理层的物理上行链路共享信道(PUSCH)和物理下行链路共享信道(PDSCH)。
LTE的物理层基于用于下行链路的正交分频多路复用(OFDM)以及用于上行链路的相关技术,单载波分频多路复用(SC-FDM)。在OFDM/SC-FDM中,根据诸如QAM(正交调幅)的调制方案的复合调制符号各自单独映射到在OFDM/SC-FDM符号期间发送的特定的OFDM/SC-FDM子载波,称为资源元件(RE)。RE是LTE中的最小物理资源。LTE还提供MIMO(多输入多输出)操作,其中通过多条天线发送和接收多个数据层,并且每个复合调制符号映射到多个发送层中的一个且然后映射到特定的天线端口。如下面要解释的,随后通过天线端口、子载波位置和无线电帧内的OFDM符号索引来唯一地标识每个RE。
在时域中的LTE发送被组织成无线电帧,每个无线电帧都具有10ms的持续时间。每个无线电帧由10个子帧构成,并且每个子帧由两个连续的0.5ms的时隙构成。每个时隙包括用于扩展循环前缀的六个索引OFDM符号以及用于正常循环前缀的七个索引OFDM符号。对应于单个时隙内的十二个连续子载波的一组资源元件被称为资源块(RB),或者相对于物理层被称为物理资源块(PRB)。
在FDD(分频双工)操作的情况下,提供单独的载波频率用于上行链路和下行链路传输,上述帧结构可不经修改而应用于上行链路和下行链路。在TDD(时分双工)操作中,为上行链路或下行链路传输分配子帧,特殊的子帧出现在从下行链路到上行链路传输的过渡处(但是不是在从上行链路到下行链路传输的过渡处)。eNB管理在TDD操作期间上行链路和下行链路子帧在每个无线电帧内的分配。
LTE控制信令
物理信道对应于用于特定传输信道的发送的时频资源集合,并且每个传输信道被映射到对应的物理信道。还存在需要支持下行链路和上行链路传输信道的发送的不具有对应传输信道的物理控制信道。这些包括物理下行链路控制信道(PDCCH),eNB通过该PDCCH将下行链路控制信息(DCI)发送到UE,并且包括物理上行链路控制信道(PUCCH),其将上行链路控制信息(UCI)从UE运载到eNB。在与本公开相关的范围内,由PDCCH运载的DCI可以包括调度信息,该调度信息将上行链路和下行链路资源分配给UE,而由PUCCH运载的UCI可以包括用于对UE接收到的传输块进行响应的混合ARQ应答。
在每个子帧的指定控制区域内发送PDCCH。PDCCH到资源元件的映射是通过基于控制信道元件(CCE)的特定结构来完成的,其中CCE是三十六个毗邻资源元件的集合。某一PDCCH所需的CCE的数量取决于所载有的DCI的尺寸。
通过将UE特定CRC(循环冗余校验)附于PDCCH,每个PDCCH可寻址到特定的UE,这还可用于错误检测。因此,UE通过进行CRC计算且查看计算是否进行校验来检测意在为其保留的PDCCH。通过在CRC计算中包括UE(或多个UE)的无线电网络临时标识符(RNTI)来使CRC为UE特定的。LTE还限定了搜索空间以限制UE需要监控从而检测意在为其保留的PDCCH的CCE的集合。
如果UE已经在要发送诸如混合ARQ应答的控制信令的上行链路子帧中被分配了PUSCH资源,则控制信令可以与PUSCH中的数据时间多路复用。否则,使用PUCCH。每个PUCCH资源由上行链路子帧的两个时隙中的每一个时隙内的一个资源块构成。来自多个UE的控制信令能够借助于时域和频域码分多路复用的组合而多路复用到单个PUCCH区域中。构成控制信令的符号乘以正交覆盖序列以实现时间的扩展,并且随后所得到的符号用于调制频域中的相位旋转(对应于时域中的循环移位)的长度12参考信号序列以实现频率扩展。因此,PUCCH所使用的资源不仅是通过其指定的资源块在时域-频域中规定,而且通过所应用的循环移位和正交覆盖序列来规定。通过将不同的循环移位和正交覆盖序列指定给不同的UE,可以通过不同的UE利用相同的时间-频率资源来发送PUCCH。
经由以刚刚描述的方式在PUCCH中码分多路复用的单个BPSK或QPSK(二进制或正交相移键控)符号来发送混合ARQ应答,以在称为格式1PUCCH的一对资源块上扩展符号。PUCCH格式1资源由PUCCH索引表示,通过LTE规范(参见3GPP TS 36.211版本10)中所描述的方式从PUCCH索引获得资源块对、相位旋转、以及正交覆盖序列。
对UE的下行链路调度指派适用于它们被发送到的同一子帧。当UE在特定子帧中接收PDSCH分配时,UE需要在指定的后续子帧中发送混合ARQ应答。UE可以使用在该后续的子帧中先前分配的上行链路资源(即,PUSCH或PUCCH资源)。否则,对于格式1PUCCH的混合ARQ应答,eNB在分配包含了将要通过表明PUCCH索引用作在检测到的PDCCH中发现的最低CCE索引的函数来应答的数据的PDSCH的同一PDCCH中分配上行链路资源。因此,eNB隐含地对上行链路资源分配给UE发出信号。
在FDD的情况下,在发送数据的下行链路子帧与发送对于该数据的混合ARQ应答的上行链路子帧之间存在一对一的对应关系。另一方面,在TDD中,上行链路和下行链路子帧的非对称分配会使得单个上行链路子帧用于应答多个下行链路子帧成为必然,后一组的下行链路子帧称为绑定窗。上文中描述的多个PUCCH资源块对和码分多路复用可用于从同一子帧中的相同的或多个UE发送多个混合ARQ应答。
用于ePDCCH的PUCCH映射方案
本文所描述的是用于TDD混合ARQ多路复用模式的PUCCH资源映射方法,TDD混合ARQ多路复用模式可以包括用于不具有在3GPP版本中定义的载波聚合的UE的多路复用以及用于对具有如3GPP版本10中定义的载波聚合的UE可进行信道选择的用于PUCCH格式1b的多路复用。在所描述的映射方案中,PUCCH资源映射隐含地基于ePDCCH的对应的最低PRB索引,从而不会发生PUCCH冲突问题。对eNB调度器也不施加任何调度约束。映射方案还允许PUCCH资源在同一绑定窗中对于不同子帧进行交错以压缩和减少PUCCH开销,并且因此增大PUSCH吞吐量。
如本文所限定的,ePDCCH由增强型控制信道元件(eCCE)构成,其中一个eCCE包括在用于定义ePDCCH到资源元件的映射的PRB对内的预定义RE的集合。图2示出了一个实施例,其中在用于ePDCCH的每个PRB对中存在四个索引eCCE。值得注意的是,eCCE可以包含为其它信号保留的RE,其它信号诸如为在图中指定为RS的CRS(小区特定的参考信号)以及CSI-RS(信道状态信息参考信号)。
对于TDD混合ARQ多路复用和绑定窗尺寸为M>1的子帧n(其中M是在3GPP TS36.213的表10.1.1中定义的集合K中的元素数量),将表示为从子帧n-ki得到的PUCCH资源,将HARQ-ACK(i)表示为用于子帧n-ki的混合ARQ响应,其中ki∈K,0≤i≤M-1。对于PDSCH传输或表明子帧n-ki中的下行链路SPS(半永久调度)释放的PDCCH,对应地用于子帧n中的混合ARQ反馈的PUCCH资源可利用如下文所描述的不同映射方案来计算。
对于在子帧n-ki中检测到的每个ePDCCH,在下面描述的示例的映射方案中使用下面的符号来确定对应的PUCCH资源索引
neCCE:在子帧n-ki中检测到的ePDCCH中的最低eCCE的索引,
0≤neCCE≤E。
E:在一个PRB中的eCCE的数量(在本文所描述的示例实施例中使用的E=4)。
包括在子帧n-ki中检测到的ePDCCH的至少一个eCCE的最低PRB索引。注意,最低PRB索引内的eCCE可以是ePDCCH资源的部分或全部。
从系统角度或UE特定角度,表示保留用于在下行链路子帧中发送ePDCCH的ePDCCH PRB的小区特定或UE特定的参数。通过较高层信令半静态地对小区特定或UE特定的参数发信号或者通过专用物理信道在每个下行链路子帧中动态地对小区特定或UE特定的参数发信号,所述专用物理信道诸如为如版本8中规定的或者如UE根据系统带宽隐含地确定为的物理控制格式信息信道(PCFICH)信道,其中是如3GPPTS 36.211定义的系统下行链路带宽配置中的PRB的数量。注意,在下面所论述的映射方案中,保留用于PUCCH传输的PUCCH资源可通过的适当设定而最小化。因此,更多的上行链路PRB可用于PUSCH传输而得到更高的上行链路吞吐量。
Δ:通过较高层提供或隐含映射,取决于绑定窗尺寸,例如,Δ=M·Q,其中Q≥1。
表示用于ePDCCH传输的最低PRB索引,通过较高层以UE特定的或小区特定的方式来配置。
表示用于ePDCCH的PUCCH资源偏移,通过较高层以UE特定的或小区特定的方式来配置。
在第一映射方案中,利用下面的等式隐含地按子帧映射PUCCH资源:

在第二映射方案中,PUCCH资源的时域第一映射连同PRB级交错是利用下面的等式来进行的:
