为了更清楚地说明本发明实施例的技术方案, 下面将对实施例或现有技 术描述中所需要使用的附图作筒单地介绍, 显而易见地, 下面描述中的附图 仅仅是本发明的一些实施例, 对于本领域普通技术人员来讲, 在不付出创造 性劳动的前提下, 还可以根据这些附图获得其他的附图。
图 1是本发明一个实施例的测量事件判决的方法的流程示意图; 图 2是本发明一个实施例的用户设备的结构示意框图;
图 3是本发明一实施例的通信系统的结构示意框图;
图 4是本发明另一实施例的用户设备的结构示意图。 具体实施方式 下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行 清楚、 完整地描述, 显然, 所描述的实施例是本发明一部分实施例, 而不是 全部的实施例。 基于本发明中的实施例, 本领域普通技术人员在没有作出创 造性劳动前提下所获得的所有其他实施例, 都属于本发明保护的范围。
本发明的技术方案, 可以应用于各种通信系统中, 例如: 全球移动通信 系统(GSM, Global System of Mobile communication ), 码分多址(CDMA, Code Division Multiple Access ) 系统, 宽带码分多址( WCDMA, Wideband Code Division Multiple Access Wireless ),通用分组无线业务 ( GPRS , General Packet Radio Service ), 长期演进 ( LTE, Long Term Evolution )等。
用户设备, 也可称之为移动终端 ( Mobile Terminal )、 移动用户设备等, 可以经无线接入网(例如, RAN, Radio Access Network )与一个或多个核心 网进行通信, UE可以是移动终端, 如移动电话(或称为"蜂窝"电话)和具 有移动终端的计算机, 例如, 可以是便携式、 袖珍式、 手持式、 计算机内置 的或者车载的移动装置, 它们与无线接入网交换语言和 /或数据。
基站,可以是 GSM或 CDMA中的基站( BTS, Base Transceiver Station ), 也可以是 WCDMA中的基站( NodeB ) ,还可以是 LTE中的演进型基站( eNB 或 e-NodeB , evolutional Node B ), 本发明并不限定。
在本发明的实施例中,采用 CoMP技术可以实现多个接入点间的信道和 数据信息共享, 有效提高整个小区性能。 CoMP的应用场景 (Scenario)可以分 为 4类:
场景 1: 同构网给(homogeneous network)下的站内 CoMP(intra-site
CoMP);
场景 2: 具有高发射功率的拉远射频头 (RRH, Remote Radio Head )的 同构网络;
场景 3: 在宏基站( Macro cell )覆盖范围内具有低发射功率 RRH的异 构网络 (Heterogeneous network) , 其中各个 RRH具有和宏基站不同的物理 'J、 区标识 (PCI , Physical Cell Identity);
场景 4: 在宏基站覆盖范围内具有低发射功率 RRH的异构网络, 其中 各个 RRH具有和宏基站相同的物理小区标识。
随着射频拉远技术的广泛应用, 例如在 CoMP场景 4下, 服务小区覆盖 范围下可能存在多个 AP, 这些 AP具有与服务小区相同的 PCI。 由于 UE在 现有测量事件判决的过程中, 同一个 PCI对应了一种测量结果, 这使得 UE 无法将这些 AP下每一个的信号测量结果都进行测量事件的判决, 也不会在 满足测量事件判决条件下, 将信号测量结果上报给基站进行小区切换。
在本发明实施例中, AP可以是各种网络节点, 包括且不限于 RRH、 射 频拉远模块(RRU, Radio Remote Unit ), 中继站、 基站等。
图 1是本发明一个实施例的测量事件判决的方法的流程示意图。
101 , UE确定多个 AP中每个 AP的第一测量结果, 所述多个 AP具有 相同的 PCI, 所述第一测量结果为 RSRP或 RSRQ。
可选地, 所述 RSRP为根据 CRS测得的 RSRP或根据 CSI-RS测得的 CSI-RSRP。
可选地, 所述 RSRQ为根据 CRS测得的 RSRQ或根据 CSI-RS测得的
CSI-RSRQ。
在本发明的实施例中, CSI-RSRP和 CSI-RSRQ的定义, 如下所示: CSI-RSRP的定义: 将从携带来自同一个 CSI-RS配置集合的 CSI 参考 信号的部分或全部资源单元上获得的功率进行线性平均来获取所述 CSI-RSRP的值。
CSI-RSRQ 的定义: 根据 Ν χ CSI-RSRP/ (测量带宽上测得的接收信号 强度指示)来获取所述 CSI-RSRQ的值, N是无线通信系统中,例如 E-UTRA ( Evolved Universal mobile telecommunications system Terrestrial Radio Access , 演进的通用移动通信系统陆地无线接入) 载波接收信号强度指示 ( RSSI, Received Signal Strength Indication ) 的测量带宽; 或者根据 Μ CSI-RSRP/ (携带 CSI-RS的所有资源单元( RE, Resource Element )上测得的 RSSI)来获取所述 CSI-RSRQ的值, M携带 CSI-RS的 RE数。
具有相同 PCI的多个 AP可以配置不同的 CSI-RS。 这些不同的 CSI-RS 具有不同的 CSI参考信令配置索引号、 不同的频域资源配置、 不同的码域资 源配置、 不同的天线端口号、 和 /或不同的子帧配置。 也就是, 在 CoMP场 景下, 同一个 PCI不仅对应了一种 CRS, 还可以对应一种或多种 CSI-RS配 置。 因此, UE可以利用同一 PCI对应的 CRS或 CSI-RS配置信息, 对相同 PCI下的一个或多个 AP的进行测量, 获取第一测量结果。
102, 所述 UE根据所述多个 AP中每个 AP的第一测量结果, 确定所述 PCI对应的第二测量结果, 所述 PCI对应的第二测量结果用于所述 UE进行 测量事件判决。 可选地, 所述 UE根据所述多个 AP中每个 AP的第一测量结果, 确定 所述多个 AP的第二测量结果, 包括: 所述 UE对所述多个 AP中每个 AP的 第一测量结果进行统计分析, 并获得统计分析后所述多个 AP的第二测量结 果。 该统计分析的方法可以是 UE预先设定, 也可以是由基站或者网络管理 系统 (例 口, 管理网元 OAM ( Operation Administration and Maintenance, 运 行、 管理和维护)) 下发的。
本领域技术人员可以理解, 上述统计分析方法可以包括中位值滤波、 维 纳滤波或算数平均值滤波等。 所述用户设备选取所述多个 AP中每个 AP的第一测量结果构成的集合 中的最大值作为所述 PCI对应的第二测量结果,例如 /( , \ieS) = maxi , \ieS}; 或者, 所述用户设备选取所述多个 AP中每个 AP的第一测量结果的加 权和作为所述 PCI对应的第二测量结果,例如 1^^) =∑(¾ ( C为加权值, 该加权值可以根据对 ,所需的降噪特性确定, C可以是 1々函数, 也可以是 常数, 例如 C为 1)或者,
所述用户设备选取所述多个 AP中每个 AP的第一测量结果构成的集合 的数学期望作为所述 PCI对应的第二测量结果, 例如 f(Xi
Figure imgf000007_0001
. 其中, S为所述多个 AP构成的集合; ,为所述多个 AP中第 '1个 AP的 第一测量结果 的单位为毫瓦); LI表示集合 S中多个 AP的数目。
作为一个示例, 如果需要选择 CoMP集合中信号最强的 AP给 UE发送 物理下行共享信道 (PDSCH, Physical Downlink Shared CHannel) , 则统计分析 的方法可以为 fix! \ieS) = maxi , \ieS} .如果 CoMP集合内所有 AP—起给 UE 发送 PDSCH, 则统计分析的方法可以选择为 /( 1^^) =∑ 。 如果 CoMP 集合内所有 AP 轮流给 UE 发送 PDSCH, 则统计 斤的方法可以为 l e5) = ^¾/l5 L
可选地 Γ上述多个 AP具有的相同 PCI可以是月良务小区的 PCI,相应地, 上述第一测量结果和第二测量结果为 UE对服务小区的测量结果。 上述多个 AP具有的相同 PCI也可以是邻小区的 PCI, 相应地, 上述第一测量结果和 第二测量结果为 UE对邻小区的测量结果。
更进一步地, 服务小区和邻小区具有不同的 PCI, UE可以获得服务小 区的多个 AP的第一测量结果以及第二测量结果, 也可以获得邻小区的多个 AP的第一测量结果及第二测量结果。 如果 UE判断出服务小区的第二测量 结果和邻小区的第二测量结果满足测量事件判决的条件, 则该 UE将服务小 区的多个 AP的第一测量结果或第二测量结果, 和邻小区的多个 AP的第一 测量结果或第二测量结果, 上报给基站, 由基站可以进行小区切换的判断。 更进一步, 当 UE给基站上报的是第一测量结果时, 基站可以根据该第一测 量结果对 UE进行小区切换判决, 并在将 UE切换到目标小区后为 UE选择 为 UE提供最好服务的 AP。 当 UE给基站上报的是第二测量结果时, 使得 UE上报的数据量较少, 不会影响 UE的用户体验(尤其是具有高优先级的 用户, 例如 VIP用户的体验), 基站可以根据该第二测量结果对 UE进行小 区切换判决, 将 UE切换到目标小区。
更进一步地, 本发明实施例还可以应用在服务小区或者邻小区下没有多 个 AP的这类场景中。 在这种情况中, 一个服务小区或者邻小区就相当于一 个 AP, 上述集合 S中的元素为 1个。
在本发明的实施例中, 多个 AP具有相同的 PCI, 因此, 这多个 AP中 的每一个的第一测量结果对应了这个相同的 PCI。 在现有测量事件判决的过 程中, UE无法根据具有同一个 PCI的多个 AP的第一测量结果进行测量事 件判决。例如,服务小区和邻小区具有不同的 PCI,服务小区下具有多个 AP, 这多个 AP与服务小区具有同一 PCI, UE可以测得这多个 AP的第一测量结 果; 邻小区下也具有多个 AP, 这多个 AP与邻小区具有同一 PCI, UE也可 以测得这多个 AP的第一测量结果。 但是, 在现有测量事件判决的过程中, 一个 PCI对应一种测量结果, 使得 UE不能够根据对应同一 PCI的多个第一 测量结果进行测量事件判决。
应用本发明实施例提供的技术方案, UE通过对具有相同 PCI的多个 AP 进行信号测量, 根据获取的多个 AP下的第一测量结果确定出具有相同 PCI 的多个 AP的第二测量结果。 UE可以根据多个 AP的第二测量结果来进行测 量事件判决, 同一个 PCI仍然对应了一个或一种用于测量事件判决的测量结 果, 从而使得 UE在不改变现有测量事件判决的情况下, 可以根据该第二测 量结果进行测量事件判决。 提高了系统的性能。 更进一步, 本发明实施例提 供的技术方案, 还可应用于服务小区和邻小区下没有多个 AP的场景, 实现 了技术方案在现有场景中的应用, 降低了系统维护的成本。 图 2是本发明一个实施例的用户设备的示意框图。 图 2的用户设备 20 包括第一确定单元 21和第二确定单元 22。
第一确定单元 21用于确定多个 AP中每个 AP的第一测量结果,所述多 个 AP具有相同的 PCI。 所述第一测量结果为 RSRP或 RSRQ。 可选地, 该 RSRQ为根据 CRS 测得的 RSRQ或根据 CSI-RS 测得的 RSRQ。
第二确定单元 22用于根据所述多个 AP中每个 AP的第一测量结果,确 定所述 PCI对应的第二测量结果,所述 PCI对应的第二测量结果用于进行测 量事件判决。
作为一种可能实现方式, 所述第二确定单元具体用于对所述多个 AP中 每个 AP的第一测量结果进行统计分析, 并获得统计分析后所述多个 AP的 第二测量结果。 该统计分析的方法可以是该用户设备预先设定, 也可以是由 基站或者网络管理系统(例如, OAM) 下发的。 所述第二确定单元 22具体用于选取所述多个 AP中每个 AP的第一测量 结果构成的集合中的最大值作为所述 PCI 对应的第二测量结果, 例如 f(xi \ i eS) = max{xi \ i eS}',
或者,所述第二确定单元 22具体用于选取所述多个 AP中每个 AP的第 一测量结果的加权和作为所述 PCI 对应的第二测量结果, 例如 f{xi \i^S) = jCxi ( C为加权值,该加权值可以根据对 ,所需的降噪特性确定, C可以是 函数, 也可以是常数, 例如 C为 1);
或者,所述第二确定单元 22具体用于选取所述多个 AP中每个 AP的第 一测量结果构成的集合的数学期望作为所述 PCI对应的第二测量结果,例如

发送单元 24, 用于在判决单元 23判断出第二测量结果满足测量事件判 决条件时, 将上述第一测量结果或上述第二测量结果上 给基站。
更进一步, 当用户设备 20给基站上报的是第一测量结果时, 基站可以 根据该第一测量结果对 UE进行小区切换判决, 并在将用户设备 20切换到 目标小区后为 UE选择为 UE提供最好服务的 AP。 当用户设备 20给基站上 报的是第二测量结果时, 可以使得用户设备 20上报的数据量较少, 不会影 响 UE的用户体验(尤其是具有高优先级的用户的体验, 例如 VIP用户的体 验 ),基站可以根据该第二测量结果对 UE进行小区切换判决, 将 UE切换到 目标小区。

应用本发明实施例提供的技术方案, UE通过对具有相同 PCI的多个 AP 进行信号测量, 根据获取的多个 AP下的第一测量结果确定出具有相同 PCI 对应的第二测量结果。 UE可以根据相同 PCI对应第二测量结果来进行测量 事件判决, 同一个 PCI仍然对应了一个或一种用于测量事件判决的测量结 果, 从而使得 UE在不改变现有测量事件判决的情况下, 可以根据该第二测 量结果进行测量事件判决, 提高了系统性能。 更进一步, 本发明实施例提供 的技术方案, 还可应用于服务小区和邻小区下没有多个 AP的场景, 实现了 技术方案在现有场景中的应用, 降低了系统维护的成本。 本发明实施例还提供一种通信系统,如图 3所示, 包括上述用户设备 20 和基站 30。用户设备 20可详细参见如图 2所示的实施例。该基站 30用于接 收用户设备发送的服务小区第一测量结果或者第二测量结果, 和邻小区的第 一测量结果或者第二测量结果, 并根据服务小区的第一测量结果或者第二测 量结果和邻小区的第一测量结果或者第二测量结果进行小区切换的判决。
