Description

用于提高无线异构网中的移动性的装置
技术领域
本公开涉及无线异构网，更具体地涉及提高无线异构网中的用户设施(UE)移动性的装置和方法。
背景技术
无线网络——例如长期演进(LTE)和LTE先进(LTE-A)网——可以是包括“宏小区”和“小型小区”的异构网，所述“宏小区”提供较高的功率/较宽的区域覆盖，而所述“小型小区”提供较低的功率/减小的区域覆盖。小型小区可包括适于家庭或办公室覆盖的“毫微微小区”和用于诸如购物中心的较大室内环境的“微微小区”。例如演进节点B(eNB)收发机的基站可关联于每个小区以提供对经过该小区覆盖区的无线移动设备(例如用户设施(UE))的网络接入。
小型小区可位于宏小区覆盖区域之内。可提供这些小型小区以给予额外的能力(例如，用于应付更多UE)，或者可提供这些小型小区以给予额外的覆盖(例如填补宏小区覆盖区内的覆盖盲区或间隙)。
当UE行进经过小型小区覆盖区时，可能需要小区切换，这可导致网络系统和UE低效以及其它问题。这些问题包括增加的服务小区信道质量检测和报告、增加的UE功耗、小区ID的冲突和短缺以及小区间过度的切换，这使无线电链路失效的风险增加。

虽然将参照说明性实施例继续进行以下详细描述，但其许多替代物、修改以及变型对本领域技术人员而言将显而易见。
具体实施方式
一般，本公开提供用于提高无线异构网中的用户设施(UE)移动性的装置和方法，所述无线异构网例如是包括宏小区和小型小区的LTE或LTE-A网络。UE(例如移动设备)可配有位置电路，它允许确定相对于检测和标识的小区的运动，例如离开和进入。UE可将该运动或接近信息发送至演进节点B(eNB)基站，并且该信息可协助eNB进行UE从一个小区至另一个切换。eNB可被配置成维持相邻小区的数据库，并且该数据库可包括每个小区的“使用类型”，其中使用类型指示该小区是用于容量增强还是覆盖增强。
在一些实施例中，当服务小区的基准信号接收功率(RSRP)低于一阈值时UE可被配置成在相邻小区上执行信号测量，并且该阈值可基于相邻小区的使用类型。UE可被进一步配置成在基于相邻小区的使用类型的时间周期内向服务小区报告信号测量。在一些实施例中，例如，当多个小型小区使用同一小区ID发送小区特定基准信号(CRS)时，eNB可被配置成标识CRS的子帧，在该子帧上UE可执行信号测量。可提供前面提到的特征以减少UE专门用于测量信号和报告测量的时间量，由此提高UE效率和网络效率。
图1示出与本公开一致的一个示例性实施例的顶层系统图100。异构无线网100以简化形式被示出以包括宏小区eNB 110、两个小型小区eNB108、112以及被配置成增强移动性的UE 114，如下文中更详细描述的那样。异构无线网100可遵循或以其它方式兼容于基于第三代合作伙伴计划(3GPP)长期演进(LTE)和/或LTE先进(LTE-A)的无线网络标准，包括该标准的当前、之前和未来版本。
小型小区可包括例如微微小区和毫微微小区。宏小区eNB 110提供小区覆盖区102，而小型小区eNB 108提供小区覆盖区104并且小型小区eNB112提供小区覆盖区106。UE 114被图示为在路径116上行进通过每个小区覆盖区，这可能导致eNB之间的切换。
本例中的小型小区eNB 108被配置为“容量”使用型小区。
也就是说，提供eNB 108以增加网络能力，这是通过处理可从更接近最大信道或资源能力的另一eNB卸载的额外UE来实现的。相对而言，本例中的小型小区eNB 112被配置为“覆盖”使用型小区。也就是说，提供eNB112以通过填补宏小区覆盖区102的覆盖区内的覆盖盲点或间隙来改善覆盖。与UE移动性关联的效率提高可通过结合由UE和eNB执行的操作利用这种小区类型使用信息而获得，如下文中描述的那样。
图2示出与本公开一致的一个示例性实施例的方框图200。UE 114被图示为位于小型小区覆盖区104、106内。该UE可包括位置确定模块202，它被配置成估计UE的位置和/或运动，尤其是UE正在离开还是正在进入小区覆盖区。在一些实施例中，位置确定模块202可基于从全球定位系统(GPS)信号或接收机208接收的信息进行估计。位置确定模块202可附加地或替代地基于所接收的小区ID 210和/或接收的WiFi服务集标识符(SSID)212进行估计。
一些已有的智能电话(UE)应用允许用户基于位置定制电话行为。例如，用户可通过该应用定义与GPS位置关联或与特定小区ID或WiFi SSID联系的某些区域。这些定义的区域可由用户规定为某一类型的区域，例如办公室区域或家庭区域，它们可关联于特定的小型小区。位置和离开/进入信息可通过应用编程接口(API)204由应用软件供UE使用。
UE的无线电资源控制(RRC)/媒体接入控制(MAC)层206控制由UE的空气接口层执行的传输。RRC/MAC层206可从API被通知和提供以位置信息。RRC/MAC层206可随后将辅助信息消息214送至网络(例如小型小区eNB108、112或宏小区eNB 110)，网路可使用该信息以执行网络优化，例如下面描述的与移动性关联的网络参数的配置。
辅助信息消息214可包括数个字段。类型字段可指示满足离开条件还是进入条件。小型小区类型字段可指示小型小区是办公室小区还是家庭小区。附加字段可指示服务小区是否为优选小型小区以及优选小型小区载波频率和/或物理小区标识(PCI)。辅助信息消息214可被纳入到已有的接近性指示RRC消息中或可被实现为新类型的RRC消息。
图3示出与本公开一致的另一示例性实施例的方框图300。UE 114可被配置成在相邻小区108、112上执行信号测量308并向当前为UE 114提供服务的服务小区eNB 302报告这些测量306。例如来自相邻小区的RSRP的信号测量一般由UE 114执行以估计UE至新的服务小区的可能转换(例如切换)的相邻小区环境。
服务小区eNB 302被图示为维持相邻小区列表304，该相邻小区列表304包括关于协助UE执行相邻小区信号测量的相邻小区的信息。该信息可包括相邻小区的使用类型(即它是容量类型小区还是覆盖类型小区)。例如，如果相邻小区是覆盖类型小区，则UE可能需要在测量报告被触发后较短时间周期内发送信号测量报告，以在从服务小区接收到切换命令之前避免与服务小区的无线电链路失效。在容量类型小区的情形下，在覆盖与宏小区重叠的情况下，无线电链路失效不大可能发生，因此测量报告的时间关键性较低。
图4-图7示出可遵循或可兼容基于3GPP LTE和/或LTE-A的无线网络标准的数据结构和/或消息字段，包括这种标准的当前、之前和未来版本。
图4示出与本公开一致的一个示例性实施例关联的数据结构400。在LTE或LTE-A系统中，相邻小区列表304提供关联于一个或多个相邻小区的信息以及这些相邻小区的关联eNB。该信息可包括载波频率、带宽和将UE114从服务小区切换至相邻小区所需的其它信息。相邻小区列表304可关联于已知为“MeasObjectEutra”415的信息要素，该信息要素可包括作为PvRC消息的一部分。在该实施例中，被标记为“usage(使用)”410的新信息字段可被添加至CellsToAddMod数据结构405，对于MeasObjectEUTRA 415中规定的每个小区均可包括它。使用字段410允许eNB 302通知UE 114相邻小区108、112的使用类型(即capacity(容量)、coverage(覆盖)或其它未来的使用类型)。替代地，如果特定频率载波内的所有小区具有相同的使用类型，则使用信息可作为独立使用字段420直接包括(例如在顶层)在MeasObjectEUTRA 415中，因为MeasObjectEUTRA 415是针对每个载波频率配置的。
图5示出与本公开一致的另一示例性实施例关联的数据结构500。一示例LTE或LTE-A系统信息块(SIB)5示出于505。如果UE 114处于闲置模式，则具有使用信息的相邻小区列表304可被提供在SIB-5505中，附加有interFreqNeighSmallCelllnfo数据结构520，它包括用于指示规定的相邻小区的容量类型或覆盖类型的使用字段。在一些实施例中，可在系统信息块(SIB)4中提供具有使用信息的相邻小区列表304，它关联于频率内测量。
UE 114可被配置成较为有利地基于所提供的使用信息调整LTE和LTE-A测量相关参数的数量，所述使用信息是对于如前所述的相邻小区108、112规定的。这些参数可包括例如s测量(s-Measure)和触发时间(timeToTrigger)，如下文将要描述的。
s测量参数可至少部分地控制与相邻小区上的信号测量的UE性能关联的测量需求，所述信号测量包括频率内、频率间和无线电间接入技术(RAT)测量。当来自服务小区的RSRP低于规定的s测量值时，或换句话说当UE和服务小区之间的无线电链路可能强度降低时，UE一般需要执行这些测量。
图6示出LTE或LTE-A MeasConfig数据结构610，该数据结构610包括已有的s-测量数据字段620。在一些实施例中，可提供额外的s测量字段、s测量加(s-Measure-add)630。UE 114可根据每个相邻小区的使用类型施加s测量620或s测量加630。例如，如果相邻小区的使用是容量类型，若服务小区RSRP低于s测量加630，则可执行该小区的测量。如果相邻小区的使用是覆盖类型或者该使用未被规定或配置，若服务小区RSRP低于s测量620，则可执行该小区的测量。替代地，可对每个频率载波提供这种使用。在这种情形下，如果测量对象中的频率载波的使用是容量，若服务小区RSRP低于s测量加630，则可执行对频率载波中的相邻小区的测量。如果测量对象中的频率载波的使用是覆盖或者该使用未被规定或配置，若服务小区RSRP低于s测量620，则可执行对频率载波中的相邻小区的测量。
提供触发时间参数以避免测量报告的频繁触发。图7示出LTE或LTE-AReportConfigEUTRA数据结构710，该数据结构710可以是RRC消息的一部分，RRC消息包括已有的触发时间字段720。触发时间参数定义一持续时间，在此期间UE 114可在测量报告事件发生后发送测量报告。在一些实施例中，可提供附加的触发时间字段、触发时间加730。例如，如果相邻小区的使用是容量类型的，则可使用触发时间加值来确定是否满足触发条件。否则，如果使用是覆盖类型或者使用未被规定或配置，则可使用触发时间值来确定是否满足触发条件。
图8示出与本公开一致的另一示例性实施例的系统图800。在异构无线网100中，许多小型小区806、808、810可位于同一地理区域内，例如室内环境，诸如簇A 802。这些小型小区可配置有共同的小区ID，在这种情形下小区ID＝1。另外示出第二簇，即簇B 804，它包括全部共享同一小区ID＝2的小型小区812、814、816。
在这种情形下，相同的CRS可在小型小区簇内的全部小型小区中传输。由于这些小型小区具有相同的小区ID，因此可从同一簇内的多个小区发送相同的主同步信号(PSS)、次同步信号(SSS)和/或CRS。UE基于CRS执行信号测量，所述CRS用于如前所述的移动性和/或接近性指示。在一些实施例中，为了减缓频率间小区检测复杂性，可相比已有LTE CRS发送密度以较低的密度发送CRS。例如，CRS可以每5ms或10ms间隔被发送。为了利用这种较粗略的周期性，eNB可为UE提供信息以标识其中发送CRS的子帧，由此允许UE使用比已有的6ms LTE测量间隙长度更短的测量间隙长度。这提高了效率，因为UE接收机负有较短时间周期的测量功能。
图9示出与本公开一致的另一示例性实施例的系统图900。在异构无线网100的这个例子中，每个簇中的小型小区具有唯一的小区ID但这些小区ID在其它簇中被复制。例如，簇A 902具有小型小区906、908、910，其小区ID为1、2和3，而簇B具有小型小区912、914、916，其小区ID同样为1、2和3。这种方法有益于避免物理层小区ID的短缺并且如果提供簇标识，则可解决簇之间的小区ID的冲突或含糊性。这种部署也有益于增加小区再划分，然而，这可能造成小区之间的切换增加。另外，UE需要检测的小型小区数不同于前面结合图8描述的前述情形。为了解决这个问题，一些实施例可采用共同探索信号，该共同探索信号可从簇内的多个小型小区发送。UE可被配置成基于该探索信号执行最初信号测量。当检测到探索信号并向eNB报告时，eNB可为每个小区配置唯一的虚拟小区ID。共同的探索信号可以是PSS、SSS或CRS，它是通过成为簇ID的虚拟小区ID产生的。每个小区也可为小区特定测量发送小区特定CRS或信道状态信息基准信号(CSI-RS)。
在一些网络配置中，例如为了增加容量，可将小型小区部署在与宏小区不同的频率下。在这种情形下，UE需要执行频率间测量以检测这些小型小区。为了降低成本，许多UE没有双信道接收机，该双信道接收机可允许同时地检测两个不同频率的信道。为此，这些UE则是使用测量间隙以在时间上切换频率，以确保当信息将被丢失在UE时服务小区在测量间隙不向UE发送。然而，对频率间测量使用测量间隙导致增加的UE功耗和中断时间，这减少了UE吞吐量。作为一种替代，一些小型小区eNB可具有双RF接收机，它能检测小型小区载波频率和宏小区UE上行链路信号两者。为了支持这个操作，宏小区可能需要对由宏小区服务的UE发送小区特定探测基准信号(SRS)配置信息和UE特定SRS配置信息。替代地，小型小区可仅基于小区特定SRS配置执行盲点检测。当小型小区检测到SRS前同步码时，小型小区可将测量报告发送给宏小区。
可在测量报告中发送的信息包括检测的UE标识和SRS的接收信噪比(SNR)。如果小型小区不提供UE特定的SRS配置，则小型小区可发送检测到的SRS序列和检测到的子帧作为UE标识的替代物。
图10示出与本公开一致的一示例性实施例的操作1000的流程图。在操作1010，从与UE的服务小区关联的eNB接收使用信息。使用信息关联于UE的相邻小区并指示相邻小区是容量类型小区还是覆盖类型小区。在操作1020，RSRP是从eNB接收的。在操作1030，确定与相邻小区关联的RSRP阈值。RSRP阈值基于与相邻小区关联的使用信息。在操作1040，基于RSRP与RSRP阈值的比较在相邻小区上执行信号测量。
图11示出与本公开一致的一个示例性实施例的平台配置1100。平台1110可以是移动通信设备，例如UE设备(智能电话)、平板电脑、膝上计算设备或被配置成发送或接收无线信号的任何其它设备。在一些实施例中，平台1110可包括处理器1120、存储器1130、输入/输出(I/O)系统1140、显示器/键盘或其它类型的用户接口(UI)1170，例如触摸屏。平台1110可进一步包括基带处理模块1150和RF处理模块1160以及一个或多个天线180，所述天线1180可形成多输入多输出(MIMO)天线系统的一部分。任何数量的平台1100可在无线网络上通过RF模块1160和天线180发送或接收信号，所述无线网络可以是LTE或LTE-A无线网络。
