Description
一种测量管理方法、 网络端设备、 测量方法和用户设备
技术领域
本发明涉及移动通信技术, 尤其涉及无线通信技术中的一种测量管理方 法、 网络端设备、 测量方法和用户设备。
背景技术
为了向用户提供诸如语音、 分组数据、 广播等各种业务内容, 无线通信 网络被广泛部署, 为了满足用户日益增长的通信质量和通信速率需求, 无线 通信技术(无线网络) 不断的演进发展。 无线通信网络已经从全球移动通信 系统(Global System For Mobile Communication, GSM ) /通用无线分组业务 ( General Packet Radio Service, GPRS )系统第 2代 /第 2.5代移动通信网络演 进到通用移动通信系统 (Universal Mobile Telecommunications System, UMTS) 第 3代移动通信网络。 而为了更好的提高频语使用效率, 满足用户飞速增长 的无线通信需求,第三代合作伙伴计划( The 3rd Generation Partnership Project, 3GPP )组织又在 UMTS的基础上提出了第 4代移动通信技术 "长期演进" ( Long Term Evolution, LTE )及其进一步演进技术 "高级长期演进" ( Long Term Evolution Advanced, LTE-A ) 。
无线通信网络通常可以通过共享系统资源来支持多用户接入, 此外无线 通信网络支持用户设备 ( User Equipment, UE ) 的移动性, 鉴于上述考虑, 为了有效利用系统资源同时为用户提供优质的业务通信, 无线通信网络需要 进行有效的资源管理。 以 LTE系统为例, 演进型基站(evolved NodeB, eNB ) 基于 eNB对上行参考信号的测量或者基于 UE对下行参考信号的测量, 可以 获得无线信道质量, 并综合考虑其他因素进行无线资源的管理, 比如综合考 虑无线信道质量、 业务分布、 邻区负载、 硬件资源、 运营商政策等进行连接 移动性控制 ( Connection Mobility Control, CMC ) ; 综合考虑无线信道质量 和资源使用情况进行资源调度(Resource Scheduling, RS ); 综合考虑无线信 道质量和业务负载进行小区间干扰协调 ( Inter-cell Interference Coordination, ICIC )等等。 其中, UE对下行参考信号测量是指 UE测量小区专用参考信号
( Cell-specific Reference Signals, CRS )并把测量结果反馈给 eNB。
而为了满足 LTE-A的性能指标, 3GPP引入了一些新的网络部署和新技 术, 新网络部署比如在传统的同构网络基础上可能引入大量的低功率节点 ( Lower Power Node, LPN )组成异构网络, 以增强热点、 小区边缘、 室内覆 盖等; 新技术比如多点协作(Coordinated Multi point, CoMP )技术, 目的在 于提高小区边缘谱效率。 这些新的网络部署和新技术的出现, 可能伴随着引 入新的载频资源, 比如只设计有相对稀疏(相对于 LTE的载频资源 )的 CRS 的载频资源或者甚至没有设计 CRS的载频资源, 从而导致目前基于 CRS获 取无线信道质量进行资源管理的方法无法满足无线资源管理的需求。

LTE系统中, 为获取前向链路(下行链路) 的无线信道质量, 对于频分
双工 (Frequency Division Duplexing, FDD ) 系统, 下行载波上设计有 CRS, 而对于时分双工 ( Time Division Duplexing, FDD ) 系统, 载波对应的下行子 帧上设计有 CRS, UE测量 CRS并把测量结果反馈给 eNB。 UE测量 CRS包 括两种形式, 一种是长周期评估且需要层 3 ( Layer3 , L3 )参与滤波的测量, 本发明实施例中称之为 L3测量; 另一种是短周期 (相对于 L3测量)评估且 不需要 L3参与滤波的测量, 本发明实施例中称之为层 1 ( Layerl , L1 )测量。
其中 L3测量所获得的无线信道质量可辅助 eNB进行 CMC管理或 ICIC 管理等无线资源管理。如图 1为 L3测量处理模型,包括 L1测量功能模块 100 和 L3滤波及报告评估功能模块 101。 L1测量功能模块 100包括两个子功能模 块: 子功能模块 100-1 ( L1釆样)和子功能模块 100-2 ( L1滤波) , 其中, 子功能模块 100-1 ( L1釆样 )对 A接收的 CRS进行釆样 (或者进行测量) , 子功能模块 100-2 ( L1滤波)对子功能模块 100-1的釆样结果进行滤波。 L3 滤波及报告评估功能模块 101 包括两个子功能模块: 子功能模块 101-1 ( L3 滤波)和子功能模块 101-2 ( L3报告评估) , 其中, 子功能模块 101-1 ( L3 滤波)对 L1周期性传递给 L3的滤波结果进行滤波, 子功能模块 101-2 ( L3 报告评估)根据 L3的滤波结果判断是否触发测量报告。 如果触发测量报告, 则 L3将测量报告发送给 eNB ( B发送测量报告) 。
其中, L1测量所获得的信道质量可以辅助 eNB进行资源调度。 L1对 CRS 进行测量滤波, 并按照和 eNB 约定的方式把结果映射成信道质量指示 ( Channel Quality Indicator , CQI )后将 CQI报告给 eNB。
为了满足 LTE-A的性能指标,尤其是达到 LTE-A对小区边缘用户的性能 要求, CoMP传输技术被提出。 CoMP传输技术被看作是提高小区边缘用户 性能, 有效抑制小区间干扰的重要技术之一。 LTE-A系统可以通过 CoMP技 术来增加高数据速率的覆盖, 从而提高小区边缘的吞吐量, 进一步提高系统 吞吐量。所谓 CoMP技术是指地理位置上分离的多个 eNB或者多个传输节点 ( Transmission Point, TP )参与和同一个 UE的数据传输。 如图 2所示为一种 CoMP部署场景示意图。 图 2中有 3个彼此相邻的小区, 小区 1的基站 200、 小区 2的射频拉远单元( Remote Radio Unit, RRU ) 201 , 小区 3的射频拉远 单元 202共享 UE 203的信道信息和分布信息,并基于这些信息进行联合调度,
共同决定 UE的调度和 /或波束赋型。其中基站 200与射频拉远单元 201和 202 之间用光纤连接。
为了满足 LTE-A高吞吐量, 高传输速率的要求,尤其达到 LTE-A对增强 热点覆盖、 小区边缘、 室内覆盖等的需求, 在传统的同构蜂窝网络基础上引 入一些低功率节点。 图 3为一种异构网络部署场景。 基站 300构成宏小区 1 , 宏小区 1的覆盖范围内部署有两个低功率节点 LPN301和 LPN302用以增强热 点覆盖, 覆盖区域 2为 LPN 301的信号覆盖范围, 覆盖区域 3为 LPN 302的 覆盖范围。 基站 300和 LPN 301、 LPN 302之间用光纤连接。
为进一步提高异构网络的系统性能, CoMP传输技术可以和异构网络结 合使用, 比如, 图 3中, UE 303同时位于宏小区 1和 LPN 301的覆盖范围内, 基站 300和 LPN 301可以共同参与 UE 303的传输。 同理, UE 304同时位于 宏小区 1和 LPN 302的覆盖范围内,基站 300和 LPN 302可以共同参与 UE 304 的传输。
如图 3所示的异构网络中, 运营商部署时可以将 LPN 301的覆盖区域 2 和 LPN 302的覆盖区域 3分别设计为独立的小区, 即分别将 LPN 301的覆盖 区域 2和 LPN 302的覆盖区域 3设计为有独立的同步信道、 物理小区标识 ( Physical Cell Identity, PCI ) 、 CRS等的小区, 此时覆盖区域 2可以记为小 区 2,覆盖区域 3可以记为小区 3。运营商部署时也可以不将 LPN 301的覆盖 区域 2和 LPN 302的覆盖区域 3设计为独立的小区, 比如, 不为覆盖区域 2 和 /或覆盖区域 3独立设计同步信道、 PCI、 CRS等, 或者设置覆盖区域 2和 / 或覆盖区域 3的同步信道、 PCI、 CRS与宏小区 1的同步信道、 PCI、 CRS相 同。
如无特别说明, 以上基站、 LPN、 RRU等在本发明实施例后续的描述中 统称为节点 (Point ) 。
CoMP技术中需要选择合适的传输节点共同参与传输, 为选择合适的传 输节点, CoMP技术提出了几个资源集合的概念。 如图 4所示, 黑色虚线 400 所包围的区域为 CoMP资源管理集合 ( CoMP Resource Management Set ) , UE对 CoMP资源管理集合中的资源执行 L3测量并把测量结果反馈给网络端 设备(比如, 基站) , 网络端设备可以利用所述反馈的测量结果选择 CoMP
测量集合, 如图 4中所示, 选择了黑色实线 401所包围的区域为 CoMP测量 集合。 UE对 CoMP测量集合中的资源执行 L1测量并把测量结果报告给网络 端设备, 网络端设备可以利用所述反馈的测量结果选择 CoMP协作集合, 如 图 4中所示, 选择了阴影区域 402为 CoMP协作集合。 CoMP协作集合 402 中的节点共同参与决定 UE405 的调度和 /或波束赋型, 而实际参与和 UE405 传输的可以仅仅是 CoMP协作集合中的部分节点, 比如节点 403和节点 404。
需要说明的是, 如前文所述, 运营商部署 LPN时可以将 LPN的覆盖区 域部署为独立的小区也可以不部署为独立小区。 可以预测, 运营商将来部署 基站时也可以根据需要将基站所覆盖的区域部署为独立的小区或者不部署为 独立小区。 如果某些节点所覆盖的区域被部署为独立的小区, 则 UE可以测 量 CRS并把 CRS反馈给网络端设备, 网络端设备可以利用所述 CRS的测量 结果选择 CoMP测量集合, UE对 CoMP测量集合中的独立小区进行测量时 也可以测量 CRS。反之,如果某些节点所覆盖的区域不被部署为独立的小区, 则需要引入 UE特定的参考信号, 如信道状态信息参考信号 (Channel-State Information Reference Signal, 简称 CSI-RS ) 。 网络端设备配置需要测量的节 点的 CSI-RS资源到 CoMP资源管理集合中, UE对 CSI-RS进行 L3测量并把 测量结果反馈给网络端设备, 网络端设备选择节点并配置对应节点的 CSI-RS 资源到 CoMP测量集合中。
基于 CSI-RS的 L3测量,在 CoMP技术中可以用于 CoMP测量集合的配 置管理, 随着无线通信网络的不断演进, 基于 CSI-RS的 L3测量也可以用于 CMC管理或 ICIC管理等。 以下详细阐述基于 CSI-RS的 L3测量管理方法。
方法一
配置基于 CRS的测量和基于 CSI-RS的测量于同一测量对象中, 通过测 量配置关系确定测量参考信号, UE执行测量。
其中配置基于 CRS的测量和基于 CSI-RS的测量与同一测量对象中, 是 指对于一个特定的频率, 配置一个测量对象, 在该测量对象中同时配置需要 测量的 CSI-RS资源。
LTE系统中, eNB会为无线资源控制 (Radio Resource Control, RRC ) 连接状态的 UE配置 L3测量,以满足 CMC管理或 ICIC管理等无线资源管理 的需求。 以 LTE系统内测量为例, 具体的, eNB为 UE配置包括以下测量参 数:
1、 测量对象(Measurement Object, MO ) : eNB可以为 UE配置多个 MO, 每个 MO为一个 LTE的频率;
2、 ^艮告配置( Reporting Configuration, RC ): eNB可以为 UE配置多个 RC, 每个 RC中配置 告触发的准则 (比如, 周期性触发或事件触发等) 、 报告触发量(比如, 参考信号接收功率(Reference Signal Received Power, RSRP )或者参考信号接收质量(Reference Signal Received Quality, RSRQ ) ) 以及其他参数。
3、 测量标识( Measurement Identity, MID ) : eNB可以为 UE配置多个 MID。
如图 5所示的 LTE L3测量管理模型,每个 MID关联一个 MO和一个 RC , 如图 5中测量标识 505关联测量对象 501和报告配置 503。通过配置多个 MID , 一个 MO可以关联多个 RC,如图 5中测量对象 502通过测量标识 506和测量 标识 507分别关联两个不同的 RC, 即才艮告配置 503和才艮告配置 504。 同样, 通过配置多个 MID, —个 RC可以关联多个 MO, 如图 5中 ^艮告配置 503分 别通过测量标识 505和测量标识 506关联到两个不同的 MO,即测量对象 501 和测量对象 502。
LTE系统内测量中, 任何小区的测量参考信号均为 CRS, UE无论测量 哪个频率上的哪个小区, UE均可以通过盲检检测到的 PCI推算出每个小区上 CRS的时频域位置, 进而对 CRS进行测量。
引入测量参考信号 CSI-RS之后, 方法一中基于 CSI-RS的 L3测量管理 方法具体包括:
配置基于 CRS的测量和基于 CSI-RS的测量于同一测量对象中, UE通过 测量配置关系确定测量参考信号, UE执行测量。
其中配置基于 CRS的测量和基于 CSI-RS的测量于同一测量对象中, 是 指对于一个特定的频率, 仅配置一个测量对象, 在该测量对象中同时配置需 要测量的 CSI-RS资源。
UE通过测量配置关系确定测量参考信号,是指 UE通过测量标识关联的 测量对象和 告配置确定测量参考信号。 具体的包括以下情形。
当一特定的测量标识所关联的测量对象配置了 CSI-RS资源,所关联的报 告配置中配置了 CSI-RS 相关的报告触发量时, 则确定测量参考信号为 CSI-RS。
当一特定的测量标识所关联的报告配置中仅配置了 CRS相关的报告触发 量, 比如 RSRP或者 RSRQ, 未配置 CSI-RS相关的报告触发量时, 则确定测 量参考信号为 CRS。
当一特定的测量标识所关联的测量对象配置了 CSI-RS资源,所关联的报 告配置中配置了不限定报告触发量的标识时, 则确定参考信号为 CRS 和 CSI-RS。
当一特定的测量标识所关联的测量对象未配置 CSI-RS资源时,则确定测 量参考信号为 CRS。 其中, 该场景下, 该测量标识所关联的报告配置中可能 配置了 CSI-RS相关的报告触发量。
UE执行测量是指 UE根据确定的测量参考信号执行测量, UE执行测量 的步骤包括:
当确定的测量参考信号为 CSI-RS 时, 则 UE执行对测量对象中配置的
CSI-RS资源的测量;
当确定的测量参考信号为 CRS时, 则 UE执行对测量对象中所配置频率 上小区的 CRS的测量;
当确定的测量参考信号为 CRS和 CSI-RS时, 则 UE执行对测量对象中 配置的 CSI-RS 资源的测量, 以及, 执行对测量对象中所配置频率上小区的 CRS的测量。
UE执行测量的步骤还包括, UE根据所述测量对象所关联的报告配置所 配置的测量报告触发类型, 判断是否上报测量报告。
如图 6所示为方法一中基于 CSI-RS的 L3管理模型, 阐释了方法一的一
种具体实现方式。
如图 6所示, 网络端设备需要 UE对两个频率上的小区 (或者节点所覆 盖的区域)进行测量, 具体的包括服务频率和非服务频率 fl , 服务频率上部 署有一些节点, 这些节点上设置了 CSI-RS。 如测量对象 601所示, 网络端设 备配置测量时, 对于服务频率, 仅配置一个测量对象, 在该测量对象中同时 配置有服务频率上需要测量的 CSI-RS资源。
通过测量配置关系, 即通过 MID所关联的 MO与 RC, UE可以确定具 体的测量参考信号, 并执行测量。 如图 6所示:
测量标识 603 关联测量对象 601和 ^艮告配置 607 , 测量对象 601配置了 CSI-RS资源, 报告配置 607配置了报告触发量信道状态信息参考信号接收功 则 UE确定测量参考信号为 CSI-RS, UE执行对服务频率上配置的 CSI-RS资 源的测量。
当然 告配置 607中的 ^艮告触发量也可以配置成信道状态信息参考信号 接收质量 ( Channel State Information Reference Signal Received Quality , CSI-RSRQ )或者其他 CSI-RS相关的报告触发量。
测量标识 604关联测量对象 601和报告配置 608, 报告配置 608中仅配 置了报告触发量 RSRP, 未配置 CSI-RS相关的触发量, 则 UE确定测量参考 信号为 CRS, UE执行对服务频率上各小区的测量, 测量参考信号为 CRS。
测量标识 605关联测量对象 601和报告配置 609 , 测量对象 601配置了
CSI-RS资源, 报告配置 609中携带了 "不限定报告触发量标识" (也可以是 其他不限定 4艮告触发量的标识, 比如, 启用所有^艮告触发量标识等), 则 UE 确定测量参考信号可以为 CRS和 CSI-RS。 UE执行测量时, 执行对服务频率 上配置的 CSI-RS资源的测量, 和, 执行对服务频率上各个小区的 CRS的测 量。需要说明的是,如果服务频率上有小区既能检测到 CRS又配置有 CSI-RS 资源, 则 UE对两者均测量。
测量标识 606关联测量对象 602和^艮告配置 607, 告配置 607配置了 报告触发量 CSI-RSRP, 但是由于测量对象 602未配置 CSI-RS资源, UE确 定测量参考信号为 CRS。UE执行对 fl上各小区的测量,测量参考信号为 CRS。
需要说明的是, 其中测量标识 605 所关联的测量配置可以和测量标识 603、 测量标识 604所关联的测量配置同时配置给一个 UE, 也可以是, 测量 标识 605所关联的测量配置只能单独配置给 UE, 即不会和测量标识 603、 测 量标识 604所关联的测量配置同时配置给一个 UE。
UE执行测量得到测量结果之后,根据测量对象所关联的报告配置所配置 的测量报告触发类型, 判断是否上报测量报告。
网络端设备接收到测量报告后, 可以利用测量报告进行 CoMP测量集合 的配置管理, 以及进行 CMC管理或 ICIC管理等。
方法二
基于 CRS的测量和基于 CSI-RS的测量被独立配置, UE执行测量。 基于 CRS的测量和基于 CSI-RS的测量被独立配置, 是指对于一个特定 的频率, 配置该频率为第一测量对象, 配置该频率上需要测量的 CSI-RS资源 为第二测量对象。
具体的, 配置该频率上需要测量的 CSI-RS资源为第二测量对象的步骤, 包括:
配置该特定频率上需要测量的所有 CSI-RS资源于一个测量对象中;或者 分别配置该特定频率上需要测量的各 CSI-RS资源于多个测量对象,具体 的, 可以每个 CSI-RS资源配置于一个测量对象, 也可以多个 CSI-RS资源配 置于一个测量对象。
UE执行测量的步骤, 包括:
UE执行对第一测量对象上小区的 CRS的测量;
UE执行对第二测量对象上 CSI-RS资源的测量。
UE执行测量的步骤还包括, UE根据第一测量对象、 第二测量对象分别 关联的报告配置判断是否触发第一测量对象、 第二测量对象上测量报告的上 报。
如图 7所示为方法二中基于 CSI-RS的 L3管理模型, 阐释了方法二的一
种具体实现方式。
如图 7所示网络端设备需要 UE对频率 fl上的小区 (或者节点所覆盖的 区域)进行测量, fl上部署有一些节点, 这些节点上设置了 CSI-RS。 如图 7 所示,网络端设备配置测量时,独立配置 fl上基于 CRS的测量和基于 CSI-RS 的测量。 图中虚线以上的测量配置 700为基于 CRS的测量配置, 而虚线以下 的测量配置 700-1为基于 CSI-RS的测量配置。
如图 7所示, 基于 CRS的测量配置 700中:
测量标识 704关联测量对象 701和^艮告配置 702。 测量标识 705关联测 量对象 701和^艮告配置 703。 其中测量对象 701配置的测量对象为频率 fl的 相关信息, 比如绝对载频号和带宽等(具体信息釆用 LTE系统的测量对象配 置) 。 而^艮告配置 702和^艮告配置 703的配置也均釆用 LTE系统的测量对象 配置。 UE测量时, 测量 fl上各小区的 CRS。
如图 7所示, 基于 CSI-RS的测量配置 700-1中:
测量标识 709关联测量对象 706和^艮告配置 707。 测量标识 710关联测 量对象 706和^艮告配置 708。 其中测量对象 706配置的测量对象为 CSI-RS资 源列表,而报告配置 707和报告配置 708配置的报告触发量为 CSI-RS相关的 报告触发量, 比如 CSI-RSRP、 CSI-RSRQ、 或者其他 CSI-RS相关的值。 UE 执行测量时, 测量测量对象 706所列的 CSI-RS资源。
如图 7所示的实现方案中, fl上的所有 CSI-RS资源被配置于同一个测量 对象中, 为更灵活的评估各个 CSI-RS资源的测量结果, fl上的 CSI-RS资源 还可以分别被独立配置于多个测量对象中, 如图 8所示, 虚线以上基于 CRS 的测量配置 800 同如图 7 中基于 CRS的的测量配置 700。 而虚线以下基于 CSI-RS的测量配置 800-1中, fl上的两个 CSI-RS资源被分别配置到两个测 量对象中, 具体配置描述如下。
测量标识 810关联测量对象 806和报告配置 808。 测量标识 811关联测 量对象 807和^艮告配置 809。 其中测量对象 806配置的测量对象为 CSI-RS资 源 1 , 测量对象 807配置的测量对象为 CSI-RS资源 2。 报告配置 808和报告 配置 809配置的报告触发量为 CSI-RS相关的报告触发量,为了更灵活的评估
各个 CSI-RS资源的测量结果, 满足不同的无线资源管理需求, 两个报告配置 可以配置不同的参数, 比如不同的报告触发准则。 UE执行测量时, 测量各个 测量对象所配置的 CSI-RS资源。
UE执行测量得到测量结果之后,根据测量对象所关联的报告配置所配置 的测量报告触发类型, 判断是否上报测量报告。
网络端设备接收到测量报告后, 可以利用测量报告进行 CoMP测量集合 的配置管理, 以及进行 CMC管理或 ICIC管理等。
