Abstract

本文一般描述了用于在无线接入网中自适应地选择用于切换的A3偏移-TTT对的用户设备(UE)和方法的实施例。在一些实施例中，UE可以基于目标小区参考信号接收功率(RSRP)来选择A3偏移值并且基于服务小区RSRP来选择触发时间(TTT)。当针对TTT，目标小区RSRP超出服务小区RSRP至少A3偏移值时，可以向eNodeB发送测量报告以进行切换。可以将A3偏移值选择为与目标小区RSRP反相关并且可以将TTT选择为与服务小区RSRP直接相关。

优先权申请
本申请要求于2012年8月8日递交的美国专利申请序列号No.13/569,443的优先权权益，其要求于2012年1月27日递交的美国临时申请序列号No.61/591,641的优先权权益，通过引用将这些专利申请的全部内容并入本文。
技术领域
实施例涉及无线蜂窝通信。一些实施例涉及HetNet移动性。一些实施例涉及小区之间的切换，包括不同小区层(cell layer)的小区之间的切换。
背景技术
蜂窝通信网络的一个问题是确定应当何时使移动设备在小区之间(即，从服务小区向目标小区)切换。一个难题是在无线链路失败前执行切换。在小的小区被较大的小区覆盖的异构网络(HetNet)中，这尤其是一个问题。更高移动性的设备使得这些切换难题日益困难。一些传统技术使用移动设备的速率来降低无线链路失败率，然而，这增加了开销和处理。
因此，存在对降低无线链路失败率的改进的切换技术的一般需要。也存在对降低无线链路失败率、提高切换效率和利用更小开销来操作的改进的切换技术的一般需要。还存在对不要求使用移动设备的速率的改进的切换技术的一般需要。还存在对降低无线链路失败率(尤其是对于快速移动的移动设备)的改进的切换技术的一般需要。还存在对适用于HetNet移动性的改进的切换技术的一般需要。

具体实施方式
以下描述和附图充分地说明了特定实施例以使得本领域技术人员能够实践它们。其它实施例可以含有结构变化、逻辑变化、电气变化、过程变化以及其它变化。一些实施例的部分和特征可以包含在其它实施例的部分和特征中，或者可以被其它实施例的部分和特征替代。权利要求书中阐述的实施例涵盖了这些权利要求的所有可用的等同物。
图1示出了根据一些实施例的蜂窝通信。例如增强型或演进型节点B(eNodeB)104的基站向小区101内的通信设备(例如UE 102)提供无线通信服务。例如eNodeB 106的基站向小区103内的通信设备提供无线通信服务。当满足某些切换准则时，可以执行从eNodeB 104向eNodeB 106的切换以切换与UE 102的通信。
根据实施例，可以自适应地选择例如偏移值和触发时间(TTT)的切换发起参数以执行从服务小区(例如小区101)向目标小区(例如小区103)的切换。在这些实施例中，可以基于某些信号(例如参考信号)的接收功率电平来选择偏移值和TTT。在一些实施例中，可以使用参考信号接收功率(RSRP)。
在一些实施例中，偏移值可以是A3偏移值。在这些实施例的一些实施例中，可以基于目标小区参考信号接收功率(tarRSRP)和源小区或服务小区RSRP(srcRSRP)中的一个或多个来选择A3偏移值。可以基于目标小区RSRP和服务小区RSRP中的一个或多个来选择TTT。在这些实施例的一些实施例中，可以基于目标小区RSRP来选择A3偏移值，并且可以基于服务小区RSRP来选择TTT。
在这些实施例中，当针对所选的TTT，目标小区RSRP持续超过服务小区RSRP至少所选的A3偏移值时，可以发起从服务小区101向目标小区103的切换。在一些实施例中，可以将A3偏移值选择为与目标小区RSRP反相关，并且可以将TTT选择为与服务小区RSRP直接相关。下面更加详细地描述这些实施例。
图2示出了根据一些实施例的切换发起准则的例子。服务小区101(图1)可以具有服务小区RSRP 201，并且目标小区103(图1)可以具有目标小区RSRP 203。在这个示例图中，服务小区RSRP 201和目标小区RSRP 203可以如所示变化，这可能是UE(例如UE 102(图1))在服务小区101内相对于目标小区103移动的情况。如图2所示，当针对TTT 207，目标小区RSRP 203持续超过服务小区RSRP 201至少A3偏移值205(即，A3事件)时，可以发起切换。在一些实施例中，UE 102可以发送针对从服务小区101到目标小区103的切换的测量报告209以发起切换。
如本文所使用的A3事件可以是当相邻小区的RSRP变得优于主小区(PCell)的RSRP(例如，服务小区RSRP)一偏移量(即，A3偏移值)时的测量报告事件。在一些实施例中，A3事件可以指的是根据3GPPT.S.36.331(第三代合作伙伴计划；技术规范组无线接入网；演进型通用陆地无线接入(E-UTRA)；无线资源控制(RRC)；协议规范(版本11))的“事件A3”，尽管这不是必需的。在这些实施例中，事件A3是切换事件并且A3偏移是用于触发切换的值。
在这些实施例中，所选的A3偏移值205可以与目标小区RSRP 203反相关，并且所选的TTT 207可以与服务小区RSRP 201直接相关。在这些实施例中，A3偏移值205和TTT 207(即，A3偏移-TTT对)的自适应选择可以提高切换效率、减少无线链路失败(RLF)并且减少切换开销，尤其是对于正在移动的UE(包括那些快速移动的UE)。基于RSRP的A3偏移-TTT对的自适应选择可以在无需估计或者使用UE的速度的情况下提高切换效率并且减少无线链路失败，尤其是对于快速移动的UE。
在一些实施例中，在无线资源控制(RRC)连接建立时(例如，在初始连接建立时)，eNodeB 104可以将A3偏移值和TTT的集合连同一个或多个阈值发送给UE 102。当UE 102进入A3事件时(即，保持A3偏移状况)，UE 102可以锁定所选的A3偏移值-TTT对，直到TTT时间。A3事件到期后，当UE 102退出A3事件时，UE 102可以解锁所选的A3偏移值-TTT对。在这些实施例中，当在A3事件外时，UE 102可以监视服务小区RSRP 201和目标小区RSRP 203并且基于一个或多个RSRP阈值来动态地选择A3偏移值-TTT对。
在一些实施例中，在A3事件期间，UE 102可以禁止选择或者重选A3偏移值205和TTT 207。A3事件可以包括当测量的目标小区RSRP 203超出测量的服务小区RSRP 201当前所选的A3偏移值205时的时间。可以在A3事件外定期执行A3偏移-TTT对的A3偏移值205和TTT 207的选择和重选，并且在A3事件期间，保持(即，不重选)所选的A3偏移值205和TTT 207。
在一些实施例中，选择A3偏移值205可以包括基于目标小区RSRP 203来选择多个A3偏移值(即，v1、v2或v3)中的一个。选择TTT 207可以包括基于服务小区RSRP 201来选择多个TTT(即，t1、t2或t3)中的一个。在这些实施例中，对于较低的目标小区RSRP 203可以选择较大的A3偏移值205，并且对于较高的目标小区RSRP 203可以选择较小的A3偏移值205。在这些实施例中，所选的A3偏移值205与目标小区RSRP 203成反比例或反相关。A3偏移值205可以是dB的形式，尽管实施例的范围并未在此方面受到限制。
在一些实施例中，目标小区RSRP 203和服务小区RSRP 201之间的差(例如，从测量的目标小区RSRP 203中减去测量的服务小区RSRP 201)可以被称为测量的A3偏移。当测量的A3偏移超出所选的A3偏移值205时，A3事件可以发生。
在一些实施例中，对于较高的服务小区RSRP 201可以选择较大的TTT207并且对于较低的服务小区RSRP 201可以选择较小的TTT 207。在这些实施例中，所选的TTT 207可以与服务小区RSRP 201直接相关或成线性比例。TTT 207可以是毫秒的形式，尽管实施例的范围并未在此方面受到限制。
在一些实施例中，可以在RRC连接建立时从eNodeB 104接收多个A3偏移值和多个TTT。在一些实施例中，多个A3偏移值和多个TTT可以是基于默认或初始A3偏移值和TTT的。在一些实施例中，可以在eNodeB 104和UE 102之间的RRC连接建立时，由eNodeB 104配置或确定A3偏移值和TTT，尽管这不是必需的。在一些实施例中，A3偏移值和TTT可以是预定的。A3偏移值和TTT可以存储在UE 102中用于如上所述的随后选择。
在一些可选实施例中，UE 102可以基于默认或初始A3偏移值和TTT来生成多个A3偏移值和多个TTT。在这些可选实施例中，可以由eNodeB104提供默认或初始A3偏移值和TTT，尽管这不是必需的。
在一些实施例中，当目标小区RSRP 203大于RSRP阈值(α)时，可以选择第一A3偏移值(v1)用于A3偏移值205，并且当目标小区RSRP 203不大于RSRP阈值(α)时，可以选择第二A3偏移值(v2)用于A3偏移值205。在这些实施例中，当服务小区RSRP 201大于RSRP阈值(α)时，可以选择第一TTT(t1)用于TTT 207，并且当服务小区RSRP 201不大于RSRP阈值(α)时，可以选择第二TTT(t2)用于TTT 207。第一A3偏移值(v1)可以小于第二A3偏移值(v2)，并且第一TTT(t1)可以大于第二TTT(t2)。在这些实施例的一些实施例中，可以在连接建立时，由eNodeB 104提供第一A3偏移值(v1)、第二A3偏移值(v2)、第一TTT(t1)、第二TTT(t2)以及RSRP阈值(α)。
在一些实施例中，可以将目标小区RSRP 203和服务小区RSRP 201划分成多个等级(N)，其中使用N-1个RSRP阈值以从N个A3偏移值和N个TTT中进行选择。在使用了三个等级(N＝3)的示例性实施例中，当目标小区RSRP 203大于第一RSRP阈值(α)时，可以选择第一A3偏移值(v1)用于A3偏移值205；当目标小区RSRP 203大于第二RSRP阈值(β)但是不大于第一RSRP阈值(α)时，可以选择第二A3偏移值(v2)用于A3偏移值205；当目标小区RSRP 203不大于第二RSRP阈值(β)时，可以选择第三A3偏移值(v3)用于A3偏移值205。当服务小区RSRP 201大于所述RSRP阈值(α)时，可以选择第一TTT(t1)用于TTT 207；当服务小区RSRP 201大于第二RSRP阈值(β)但不大于第一RSRP阈值(α)时，可以选择第二TTT(t2)用于TTT 207；并且当服务小区RSRP 201不大于第二RSRP阈值(β)时，可以选择第三TTT(t3)用于TTT 207。第一A3偏移值(v1)可以小于第二A3偏移值(v2)，第二A3偏移值(v2)可以小于第三A3偏移值(v3)(即，v1<v2<v3)。第一TTT(t1)可以大于第二TTT(t2)，第二TTT(t2)可以大于第三TTT(t3)(即，t1>t2>t3)。在这些实施例中，可以在连接建立时，由eNodeB 104提供第一A3偏移值、第二A3偏移值和第三A3偏移值、第一TTT、第二TTT和第三TTT，以及第一RSRP阈值和第二RSRP阈值。
在这些实施例中，第一RSRP阈值(α)可以比第二RSRP阈值(β)大高达3dB或更多，尽管实施例的范围并未在此方面受到限制。在一些实施例中，N可以大于或等于二并且小于五，尽管实施例的范围并未在此方面受到限制(因为N可以大于五)。在一些实施例中，系统可以基于针对以不同速度移动的UE而执行的仿真来确定RSRP阈值(α、β)以最小化或减少无线链路失败并且减少切换开销。
在N＝2的示例性实施例中，eNodeB 104可以提供单个RSRP阈值和两个不同的A3偏移值和两个不同的TTT。对于N＝3，可以提供两个RSRP阈值、三个不同的A3偏移值和三个不同的TTT。对于N＝4，可以提供三个RSRP阈值、四个不同的A3偏移值和四个不同的TTT。在这些实施例中，UE 102可以基于测量的目标小区RSRP和服务小区RSRP以及RSRP阈值来选择A3偏移-TTT对以进行切换发起。
在一些实施例中，当针对所选的TTT 207，目标小区RSRP 203持续超过服务小区RSRP 201至少所选的A3偏移值205时，UE 102可以向服务eNodeB 104发送或传输测量报告209，以由服务小区101的eNodeB 104使用其进行可能的切换决策。测量报告209可以至少包括目标小区103的小区标识符。可以响应于测量报告209来执行切换。
在一些实施例中，测量报告209可以包括服务小区RSRP 201和在TTT计时器到期时测量的目标小区RSRP 203。测量报告209还可以包括其它相邻小区的RSRP。在一些实施例中，测量报告209可以被称为触发测量报告。在这些实施例的一些实施例中，可以将具有最大/最强RSRP的相邻小区识别为目标小区103。测量报告209可以通过小区的物理小区标识符(physcellid)来识别小区，并且在一些实施例中，测量报告209可以包括所述小区的封闭用户组(CSG)标识。在一些可选实施例中，可以使用测量报告209来触发到目标小区的切换并且测量报告209可以不必包括RSRP值。
在这些实施例的一些实施例中，当服务eNodeB 104决定将UE 102切换至目标小区103的eNodeB 106时，服务eNodeB 104可以向目标eNodeB106发送切换请求。目标eNodeB 106可以用切换请求确认(ACK)来响应。然后服务eNodeB 104可以利用包括移动性控制信息(例如，mobilityControlInfo)的RRC重配置消息来通知UE 102。然后服务eNodeB104可以向目标eNodeB 106传送状态(status)并且UE 102可以利用RRC连接重配置消息来切换至目标eNodeB 106以完成切换过程。
在一些实施例中，当目标小区RSRP 203超出服务小区RSRP 201至少所选的A3偏移值205时，UE 102可以设置TTT计时器。TTT计时器可以被配置成在所选的TTT 207后到期。当目标小区RSRP 203没有超出服务小区RSRP 201至少所选的A3偏移值205时，UE 102可以停止TTT计时器。当目标小区RSRP 203超出服务小区RSRP 201至少所选的A3偏移值205时，可以重置和重启TTT计时器。TTT计时器到期之后，UE 102可以向服务eNodeB 104发送测量报告209。
在一些实施例中，UE 102可以被配置为定期测量目标小区103的RSRP和服务小区101的RSRP。目标小区103的RSRP(即，目标小区RSRP 203)可以基于目标小区eNodeB 106发送的下行链路参考信号在信道带宽上的平均值。服务小区101的RSRP(即，服务小区RSRP 201)可以基于服务小区eNodeB 104发送的下行链路参考信号在信道带宽上的平均值。在这些实施例中，RSRP可以是由UE 102执行的对下行链路参考信号在信道带宽上取线性平均值的物理层测量结果。可以在层一(L1)和层三(L3)滤波后生成该值。在一些实施例中，可以根据UTRAN LTE标准之一来执行RSRP测量，尽管这不是必需的，所述UTRAN LTE标准包括针对含有TS 36.331的UTRAN-LTE 3GPP的第三代合作伙伴计划(3GPP)标准。
在一些实施例中，RSRP可以是携带小区特定参考信号的一些或全部资源元素的功率在整个带宽上的平均值，并且在携带所述参考符号的正交频分复用(OFDM)符号中测量RSRP。在这些实施例中，由不同的eNodeB发送的参考信号可以通过它们的小区标识符来区别，尽管这不是必需的。
在图1示出的例子中，目标小区103和服务小区101可以包括相同的小区层。在这些实施例中，所述相同的小区层可以包括宏小区层或微小区层。
在一些其它实施例中，目标小区103和服务小区101可以包括不同的小区层。所述不同的小区层可以包括宏小区层和微小区层。宏小区层可以包括宏小区。微小区层可以包括微小区、微微小区和毫微微小区中的一个或多个。在这些实施例的一些实施例中，如图3所示，微小区层的小区可以位于宏层的小区内。
图3示出了根据一些实施例的在不同的小区层内的蜂窝通信。在这些示例性实施例中，eNodeB 304可以是宏eNodeB并且可以在宏小区层的宏小区301内提供通信服务。eNodeB 306可以是微小区eNodeB并且可以在微小区层的微小区303内提供通信服务。微小区303可以位于宏小区301内。在这些实施例中，如上文所讨论的，UE可以基于服务小区RSRP和目标小区RSRP来动态地选择A3偏移-TTT对并且基于A3偏移-TTT对来发起切换。这些实施例在包括不同规模/层的小区之间的切换的异构网络(HetNet)(即，具有不同的小区层)中是特别有益的。

尽管UE 400被示出为具有若干单独的功能元件，但是一个或多个所述功能元件可以被组合并且可以由软件配置的元件(例如处理元件，包括数字信号处理器(DSP)、和/或其它硬件元件)的组合来实现。例如，一些元件可以包括一个或多个微处理器、DSP、专用集成电路(ASIC)、射频集成电路(RFIC)以及用于执行至少本文所描述的功能的各种硬件和逻辑电路的组合。在一些实施例中，功能元件可以指的是在一个或多个处理元件上操作的一个或多个过程。

在一些实施例中，UE 400可以被配置为根据OFDMA通信技术接收多载波通信信道上的OFDM通信信号。OFDM信号可以包括多个正交子载波。在一些宽带多载波实施例中，eNodeB可以是宽带无线接入(BWA)网通信网络(例如第三代合作伙伴计划(3GPP)通用陆地无线接入网(UTRAN)长期演进(LTE)或者长期演进(LTE)通信网络)的一部分，尽管实施例的范围并未在此方面受到限制。在这些宽带多载波实施例中，可以将UE 400和eNodeB配置成根据用于3GPP-LTE的正交频分多址(OFDMA)技术来通信。
在一些LTE实施例中，无线资源的基本单元是物理资源块(PRB)。PRB可以包括频域中的12个子载波×时域中的0.5ms。可以(在时域中)成对地分配PRB。在这些实施例中，PRB可以包括多个资源元素(RE)。RE可以包括1个子载波×1个符号。

在一些实施例中，OFDMA技术可以是使用不同的上行链路频谱和下行链路频谱的频域双工(FDD)技术或是使用相同的上行链路频谱和下行链路频谱的时域双工(TDD)技术。
在一些实施例中，UE 400可以是便携式无线通信设备的一部分，便携式无线通信设备例如个人数字助理(PDA)、具有无线通信能力的膝上型计算机或者便携式计算机、web平板电脑、无线电话、无线手持机、寻呼机、即时消息设备、数字相机、接入点、电视机、医疗设备(例如，心脏速率监视器、血压监视器等)、或者可以无线地接收和/或发送信息的其它设备。
在一些LTE实施例中，UE 400可以计算若干个不同的反馈值，所述不同的反馈值可以被用来执行用于闭环空间复用传输模式的信道适配。这些反馈值可以包括信道质量指示符(CQI)、秩指示符(RI)和预编码矩阵指示符(PMI)。发射机通过CQI来选择若干个调制符号集和码率组合中的一个。RI通知发射机关于当前MIMO信道的有用传输层的数量，并且PMI指示在发射机处应用的预编码矩阵的码本索引(取决于发射天线的数量)。eNB使用的码率可以是基于CQI的。PMI可以是由UE 400计算并且被报告给eNB的矢量。在一些实施例中，UE 400可以发送包含有CQI/PMI或RI的、格式2、2a或2b的物理上行链路控制信道(PUCCH)。
在这些实施例中，CQI可以是如UE 400所经历的下行链路移动无线信道质量的指示。CQI允许UE 400向eNB建议针对给定无线链路质量要使用的最优调制方案和编码率，使得产生的传输块差错率不超过某一值，例如10％。在一些实施例中，UE 400可以报告宽带CQI值，所述宽带CQI值指的是系统带宽的信道质量。UE 400还可以报告某一数量的资源块的每个子带的子带CQI值，这可以由较高层来配置。子带的完整集合可以覆盖系统带宽。在空间复用的情况下，可以报告每个码字的CQI。
