基站 2在向基站 1发送的 X2接口建立请求 (X2 setup request) 消息, 所述请求 消息中携带基站 2下的小区及相邻小区的小区信息;
基站 1在向基站 2发送的 X2接口建立响应(X2 setup response)消息, 所述响应 消息中携带基站 1下的小区及相邻小区的小区信息。
另一方面, 当基站 1和基站 2通过 S 1接口建立连接时, 可以通过移动管理实体
(MME, mobility management entity) 进行信令交互, 以使得基站 1和基站 2获取各 自基站以及相邻基站下各小区的小区信息。
其中步骤 111为可选步骤。
步骤 112: 基站确定 UE的测量信息, 所述测量信息可以包括该 UE的服务小区 信息和相邻的同频, 异频的小区的信息, 比如包括, 小区所在载波的类型 (普通载波 或新载波类型的载波;), 测量信息 (包括测量配置信息) 等。
本发明实施例中的所述普通载波为传统的后向兼容载波,所述新类型载波为增强 型的非后向兼容载波, 可以为在 Release-11版本里 3GPP提出的一种新的载波类型一 新载波类型 NCT。 NCT被考虑作为一种非后向兼容的载波, 可以通过修改现有的机 制以增强载波性能, 例如: 增强频谱效率、 提高异构网络支持、 节能等。
为了实现上述性能的提升, 本发明实施例提供给 UE的测量信息可以包括: 发现 参考信号 (DRS, discovery reference signals ) , 用于小区发现和 /或测量; SS (包括 PSS/SSS), 用于小区发现, 该信令可选; CSI-RS, 主要用于 CSI值的上报; 以便于 UE利用以上的信息来进行小区发现和 /或测量。
步骤 113 : 所述基站向用户终端下发测量信息, 以指示所述用户终端对指定的小 区进行测量。
本发明实施例中可以由基站通过无线资源控制 (RRC, radio resource control) 消 息向用户设备下发测量任务 (即测量信息), 但不仅限于此。
每个测量任务包括: 测量实体信息(measurement object)和报告配置信息(report configuration) ,测量实体信息用于指示需要 UE进行测量的指定小区 /载波; 报告配置 信息用于确定触发 UE向基站发送测量报告的配置信息。其中, 测量实体信息和报告 配置信息是测量任务中的信元消息,基站可以优选的将参考信号指示信息携带于测量 实体信息中, 也可以携带于报告配置信息中, 此处不做限定。
测量实体信息中包括以下至少一种组合: 相邻小区标识, 测量类型配置信息, 测 量信令配置信息和报告配置信息。
基站发送给 UE的传统的小区配置是基于小区特定参考信号(CRS, cell reference signaling )/信道状态信息参考信号 ( CSI-RS, channel-state information reference signal ) 的传统测量配置; 基站给增强的小区配置新型的测量方式。
其中,相邻小区标识 (如果是 RLM测量或 CSI上报测量,则不需要): PCI, DRS (集) 标识, CSI-RS(集)标识中的至少一项的组合。
本发明实施例中的 DRS, 是一种新型的用于小区发现 /小区识别 /小区测量的信号
("/"表示"禾 P/或"关系), 也可以叫做追踪参考信号(TRS, Track reference signals), 发现信号 (DS, discovery signals)等, 名称不限于此。
新型的测量方式:如果测量任务中包括 RRM测量,则是 UE利用 DRS进行测量; 如果测量任务中包括 CSI上报的测量, 则是 UE利用 CSI-RS进行测量; 如果测量任 务中包括 RLM测量, 则 UE利用 DRS或 CSI-RS进行测量。
测量信令配置信息: DRS的配置信息, DRS的配置信息包括: 天线端口信息(天 线端口信息可以是天线数和 /或天线端口号);频域资源配置信息;码域资源配置信息; 子帧配置信息 (包括子帧偏移信息和周期信息); 以及 UE假定的 PDSCH和 DRS的 传输功率的比值。 所述测量信息中还可以包括; 被测量小区的同步信息, 如 SFN shift/subframe shift/symbol shift等。 另夕卜, DRS的配置可以是全集子帧或者是 DRS 子帧的子集。在被测小区有 ABS配置时, UE可以取该测量配置集合和限制性测量下 发的集合的交集进行测量。
报告配置信息: 增加底层向高层上报的测量的周期值。 可选的, 该值需要考虑 DRS的精度和传输周期,如图 12所示, 图 12为本发明实施例提供的一种上报测量的 周期值的示意图。
如图 15所示, 小区 1和小区 2发送 DRS信号和 SS (同步信号), 小区 1的 DRS 的单位子帧上的信号密度较大, 1个子帧的测量即可以满足测量精度, 所以, 测量上 报给高层的周期是 3ms; 而小区 2的 DRS的单位子帧上的信号密度较小, 2个子帧 的测量才可以满足测量精度, 所以, 测量上报给高层的周期是 4ms; 小区 3和小区 4 发送 DRS信号也具有同步信号的功能,小区 3的 DRS的单位子帧上的信号密度较大, 1个子帧的测量即可以满足测量精度, 所以, 测量上报给高层的周期是 lms; 而小区 4的 DRS的单位子帧上的信号密度较小, 2个子帧的测量才可以满足测量精度, 所 以, 测量上报给高层的周期是 2ms。
在该实施例中, 上述测量配置消息还可以包括被测小区的测量指示信息, 如 m-RSRP测量指示信息和 /或 m-RSRQ测量指示信息 (m可以是 CRS, CSI-RS, 禾口 / 或 DRS); 上述测量配置消息还可以包括测量上报方式指示信息, 用于指示 UE对被 测小区进行周期性测量上报或事件性测量上报;如果测量上报方式指示信息指示的上 报方式是事件性测量上报, 则测量信息中还可包括配置迟滞值和迟滞时间,最大报告 被测小区数以及报告次数, 和 /或其他辅助配置参数, 如层三平滑过滤等参数。 如果 测量上报方式指示信息指示的上报方式是周期性测量上报,则测量配置消息中还可包 括配置报告周期, 当然,上述各参数也可是默认预置在 UE中的,本实施例不作限定。
步骤 114、 UE根据接收到的测量信息对被测小区对应的配置的信号进行测量, 获取测量结果; 并将所述测量结果上报基站;
UE在接收到基站发送的测量信息后, 可根据测量信息中的被测小区的 RS配置 信息和 /或该被测小区的配置标识 (如天线端口信息或 CSI-RS/DRS 配置信息的配置 索引号等) 的差异来区分相同物理小区标识指示的不同被测小区并进行测量的操作。 UE可利用被测小区的信令配置信息对相应的被测小区进行测量, 获取该被测小区的 测量结果, 如被测小区的 DRS-RSRP禾 P/或 DRS-RSRQ等。 进一步, UE还可以将测 量结果和测量配置消息中的信令的配置信息、被测小区的配置标识和测量索引号中的 至少一个进行绑定。在实际应用中, UE可以周期性地测量上报被测小区的测量结果, 若 UE 接收到的测量配置消息包含测量指示信息, 如 m-RSRP 测量指示信息和 /或 m-RSRQ测量指示信息, 则 UE可依据测量指示信息获取基站所需要的测量值, 将该 测量值作为测量结果上报给基站,例如,若基站发送测量信息中包含 D-RSRP测量指 示信息,则 UE获取被测小区的 D-RSRP,若测量信息中包含 D-RSRQ测量指示信息, 则 UE获取被测小区 D-RSRQ。
步骤 115: 所述基站接收所述用户设备上报的测量报告, 所述测量报告中包括所 述用户设备根据所述测量任务测量所述指定小区 /载波得到的测量结果, 根据所述测 量报告对所述 UE进行管理。
如果测量任务是 RRM测量, 基站在获取测量报告后, 能够根据测量结果确定指 定小区 /载波的信号质量和信号强度, 从而便于基站对用户终端和该指定小区 /载波进 行管理, 例如: 基站决定是否为该用户终端增加新的载波, 增加 COMP集合中的小 区或者对该指定小区 /载波进行维护, 或者是决定小区间切换的场景等。 如果测量任务是 CSI上报, 基站在获取测量报告后, 能够根据测量结果确定 UE 在服务小区 /载波 (集) 的信号质量, 从而便于基站对用户终端的调度机制的确定。
应用实例二
该应用实例二与应用实例一的不同之处在于:
步骤 114中, UE对被测小区对应的配置的信令进行测量方式不同;
本应用实例中, 首先, UE要根据新的机制, 自主的选择测量的信令类型和测量 方式。
一种选择方式: 如果 UE连接在宏小区上, 在 UE的服务小区的信号水平和 /或信 号质量高于某个门限, 例如, RSRP>某个门限, UE便应用 DRS measurement type来 做邻区测量; 反之, 如果 UE的服务小区的信号水平和 /或信号质量高于某个门限, 例 如, UE在小区的边缘, RSRP<某个门限, UE便应用 'CRS or CSI-RS or DRS with CRS/CSI-RS measurement type, 来做邻区测量。
如果 UE连接在小小区, 如 NCT小区, UE便应用 DRS measurement type来做邻 区测量。 本实施例中所述的邻区, 可以是同频邻区, 也可以是异频邻区, 本实施例不 作限制。
另一种选择的方式, UE也可以根据历史的测量信令来掌握特定场景下, 小区的 无线信号变化情况, 选择测量信令种类和类型, 比如: 小区的无线信号变化比较快, 为了避免单独依赖 DRS测量造成的乒乓切换和过早切换, 可以采用 CRS, DRS混合 测量; CSI-RS,DRS混合测量; 或者 DRS,CRS,CSI-RS混合测量的方法。 举例说明, UE首先通过测量 DRS获得相邻小区的初始值, 然后通过对 CRS和 /或 CSI-RS的测 量来满足后面的迟滞和 TTT的上报要求。
然后, UE可根据测量配置消息中的被测小区的 RS配置信息和 /或该被测小区的 配置标识(如天线端口信息或 CSI-RS/DRS配置信息的配置索引号)的差异来区分相 同物理小区标识指示的不同被测小区并进行测量的操作。 UE可利用被测小区的信令 配置信息对相应的被测小区进行测量, 获取该被测小区的测量结果, 如被测小区的 DRS-RSRP禾 P/或 DRS-RSRQ等。 可选的, UE可将测量结果和测量配置消息中的信 令的配置信息、被测小区的配置标识和测量索引号中的至少一个进行绑定。在实际应 用中, UE可周期性地测量上报被测小区的测量结果, 若 UE接收到的测量配置消息 包含测量指示信息, 如 m-RSRP测量指示信息和 /或 m-RSRQ测量指示信息, 则 UE 可依据测量指示信息获取基站所需要的测量值, 将该测量值作为测量结果上报给基 站, 例如, 若测量请求消息中包含 D-RSRP测量指示信息, 则 UE获取被测小区的 D-RSRP, 若测量请求消息中包含 D-RSRQ 测量指示信息, 贝 U UE 获取被测小区 D-RSRQ。
本发明实施例可以应用在 CoMP通信系统中,该通信系统中包括多个相互连接的 接入点或传输点, 如基站, 这些基站可以是宏基站 (Macro e B, 或者 e B), 或者 微基站 (可以是 Pico, Relay, HeNB, HNB, RRH)等, 在此不作限定, 总之是一个 站点或传输点。
在本发明实施例中, 以 eNB举例表示与宏小区对应的宏基站, 以 RRH举例表示 与微小区对应的微基站。通常无线通信系统可以分为同构网络通信系统和异构网络通 信系统, 其中, 同构网络通信系统中相互连接的基站均为宏小区基站, 异构通信系统 中相互连接的基站可以为宏小区基站和微小区基站。上述 CoMP通信系统中的所有基 站一起为终端提供服务, 该终端通常指 UE (User Equipment, 用户设备), 也可以叫 用户终端, 或者终端。
在本发明实施例中, UE可以为以下任意一种, 可以是静态的, 也可以是移动的, 静止的 UE 具体可以包括为终端 (terminal )、 移动台 (mobile station ) 用户单元 ( subscriber unit) 或站台 (station) 等, 移动的 UE具体可以包括蜂窝电话 (cellular phone ) 个人数字助理(PDA, personal digital assistant ) 无线调制解调器(modem), 无线通信设备、手持设备( handheld)、膝上型电脑( laptop computer )、无绳电话( cordless phone)或无线本地环路(WLL, wireless local loop) 台等, 上述 UE可以分布于整个 无线网络中。
需要说明的是, 在本文中, 诸如第一和第二等之类的关系术语仅仅用来将一个实 体或者操作与另一个实体或操作区分开来,而不一定要求或者暗示这些实体或操作之 间存在任何这种实际的关系或者顺序。 而且, 术语 "包括" 、 "包含"或者其任何其 他变体意在涵盖非排他性的包含, 从而使得包括一系列要素的过程、 方法、物品或者 设备不仅包括那些要素, 而且还包括没有明确列出的其他要素, 或者是还包括为这种 过程、 方法、 物品或者设备所固有的要素。 在没有更多限制的情况下, 由语句 "包括 一个…… " 限定的要素, 并不排除在包括所述要素的过程、 方法、物品或者设备中还 存在另外的相同要素。
通过以上的实施方式的描述,本领域的技术人员可以清楚地了解到本发明可借助 软件加必需的通用硬件平台的方式来实现, 当然也可以通过硬件,但很多情况下前者 是更佳的实施方式。基于这样的理解,本发明的技术方案本质上或者说对现有技术做 出贡献的部分可以以软件产品的形式体现出来,该计算机软件产品可以存储在存储介 质中, 如 ROM/RAM、 磁碟、 光盘等, 包括若干指令用以使得一台计算机设备(可以 是个人计算机, 服务器, 或者网络设备等)执行本发明各个实施例或者实施例的某些 部分所述的方法。
以上所述仅是本发明的优选实施方式, 应当指出, 对于本技术领域的普通技术人 员来说, 在不脱离本发明原理的前提下, 还可以作出若干改进和润饰, 这些改进和润 饰也应视为本发明的保护范围。
