Description

邻区测量方法和设备
技术领域
本发明涉及通信技术, 尤其涉及一种邻区测量方法和设备。 背景技术
在无线通信系统中, 网络会分成很多的小区(Cell) , 一般而言, 一个小 区内会有一个基站。用户设备(User Equipment, 简称: UE)会与某一个(或 多个) 基站建立连接, 随着 UE 的移动, 它可能会离开一个小区, 而进入另 外一个小区。 这样 UE会断开与原来的基站的连接, 而建立与新到达的小区 的基站的连接, 改由新到达的小区的基站来服务, 该过程称为切换 (handover) 。 在切换之前, UE首先需要判断除了正在保持连接的小区, 附 近是否还有其他的小区, 这些小区的信号质量如何, 如果周围有其他小区的 信号质量好于正在保持连接的小区, 或者满足其他的切换条件, 那么网络就 会启动切换流程,将这个 UE切换到更合适的小区上去。这就需要 UE对周围 的小区进行 "小区发现与测量" , 这里的测量, 就是去测量周围小区的信号 强度, 在 LTE中, 对于邻居小区的测量量 (metric) —般包括参考信号接收 功率 (Reference Signal Received Power, 简称: RSRP ) 和参考信号接收质量 (Reference Signal Received Quality, 简称: RSRQ) 。这两个测量量都能反应 目标小区的信号质量。 在长期演进(Long Term Evolution, 简称: LTE) 网络 中也称这样的测量叫做无线资源管理 (Radio Resource Management, 简称: RRM) 测量。 在目前的通信系统中, UE 主要是根据周围基站下发的小区专 用参考信号 (cell specific reference signal, 简称: CRS ) 来进行测量的。
随着通信技术和网络技术的进歩, 某些基站可能不会持续发送 CRS, 而 是周期性间隔地发送。并且基站可能会采用除了 CRS之外的参考信号来用于 UE进行 RRM测量, 例如信道质量估计参考信号 ( channel state information- reference signal , 简禾尔: CSI-RS ) , 发现参考信号 (Discovery reference signal, 简称: DRS ) 。 例如支持新载波类型 (New Carrier Type, 简称: NCT) 、 小 小区等技术的基站, 这时, 按照现有技术的方法无法进行邻区 RRM测量。 发明内容

UE进行邻区发现和邻区测量主要是通过检测基站发送的 CRS来完成 的。本发明实施例是针对新的通信技术中基站不再持续发送 CRS、 CSI-RS 或 DRS等用于 RRM测量的参考信号的场景下,提供邻区测量和邻区发现 的方法。 基站不再持续发送用于 RRM测量的参考信号的场景的一个例子 为新载波类型 NCT, 在新载波类型中, 为了降低 CRS带来的网络干扰和 能量损耗, CRS将只是周期性的间隔发送, 而非持续发送。 例如, 每 10 个连续的子帧中, 只有子帧第 1个和第 6个子帧中发送 CRS。 另一个例子 为小小区开关技术 (small cell on/off) , 小小区开关是针对于小小区网络 而言的。传统的 LTE无线网络是由宏基站组成的, 宏基站就是常见的塔状 的基站, 这些基站由于架设得较高, 发射功率大, 往往可以覆盖较大的面 积, 服务很多的用户。 但是, 随着城市的发展, 持续架设宏基站遇到了很 多挑战, 例如选址困难, 密度难以增加等。 所以现在业界推出了小基站或 微基站, 小基站的特点是其发射功率低, 安装方便, 通常不能架设很高。 所以小基站的覆盖范围通常很小, 服务的用户数也较少。 这种小基站或微 基站尤其适用于人口密集的住宅或商业区, 例如在商场里, 可以布置多个 小基站, 用来给 UE提供服务。 出于节电和降低干扰的考虑, 如果没有用 户需要服务, 小基站可以关闭; 当有用户来到这个小基站附近时, 再将该 小基站打开。 这就是所述的小小区开关技术。 小小区在关闭状态下并非什 么都不发送, 而是会按照一定的周期去发送下行参考信号 (也称为发现参 考信号, discovery reference signal, 简称: DRS ) , 以便于 UE能够发现这 些处于关闭状态的小小区。 UE也需要测量这些小小区的参考信号的接收 信号质量, 并将测量的结果上报给网络侧, 这样一旦这些小小区打开, 网 络侧可以很快将 UE切换到这些小小区上。但是由于 DRS只是周期性的发 送, 现有技术的方法是无法通过 DRS来进行 RRM测量的, 本发明实施例 则可以提供对应的测量方法和设备。
图 1为本发明提供的 UE实施例一的结构示意图, 如图 1所示, 本实 施例的 UE 100可以包括:
接收模块 101, 用于接收基站发送的至少两个互相独立的无线资源管理 RRM测量流程的配置信息, 所述 RRM测量流程是基站根据待测邻区的信息 配置的;
测量模块 102,用于采用至少两个所述互相独立的 RRM测量流程对一个 载波进行 RRM测量, 并分别获得至少两个 RRM测量结果;
发送模块 103, 用于将所述 RRM测量结果上报给所述基站。
进一歩具体地, 每个所述 RRM测量流程的配置信息包括一组测量时域 信息和对应的测量参数信息;
所述接收模块 101, 具体用于接收基站发送的至少两组测量时域信息和 每组所述测量时域信息对应的测量参数信息。
而现有的 RRM测量过程中,基站通常只为载波配置一个 RRM测量流程, 即每个载波对应一组测量时域信息及其对应的测量参数信息。 下面以小小区 的网络为例来说明本实施例的 UE如何进行现有技术的 RRM无法进行的邻区 测量。 假设网络中有三个小小区, 分别是第一小小区、 第二小小区和第三小 小区, 图 2a为三个小小区发送发现参考信号以及 UE的测量时域信息的示意 图, 图 2a中横轴代表时间轴, 三个小小区的时间轴上灰色的小方块代表有信 号传输的子帧, 如图 2a所示, 第三小小区处于打开的状态, 持续进行下行信 号的传输; 而第一小小区和第二小小区处于关闭状态, 仅仅周期性地发送一 些 DRS。 (图 2a中所示出的例子中第一小小区和第二小小区发送 DRS的周 期一致, 在相同的子帧上发送 DRS, 但实际网络中不同的小小区处于关闭状 态时发送 DRS的周期可能不一致)。如果采用现有技术进行小区测量与发现, 基站给 UE配置一组测量子帧作为测量时域信息, 如图 2a中现有技术的测量 子帧 (实线表示) , 让 UE在这组测量子帧上进行 RRM测量, 那么, 该 UE 能够测量到第三小小区的 DRS, 但不一定能测量到第二小小区或第一小小区 的 DRS。 具体地, 只有当这组测量子帧与第一小小区和第二小小区发送 DRS 的周期均匹配时, 才能够测量到第二小小区发送 DRS, 若这组测量子帧与第 二小小区发送 DRS的周期不匹配, 则无法测量到第二小小区; 若与第一小小 区发送 DRS的周期不匹配, 则无法测量到第一小小区。 由于处于关闭状态的 第一小小区和第二小小区发送 DRS的周期可能不同,实际上这组测量子帧与 第一小小区和第二小小区发送 DRS的周期均匹配的概率非常低, 因此按照现 有技术的 RRM测量进行测量结果间的平均与滤波, 会造成测量结果的偏差。
而在本实施例的 UE,通过接收模块 101接收基站发送的至少两组测量时 域信息(如图 2a中一组实线表示的子帧和一组虚线表示的子帧)和每组所述 测量时域信息对应的测量参数信息, 即可以针对不同的小小区配置不同的测 量时域信息,使每组测量时域信息分别与一个小小区发送 DRS的周期相匹配, 如图 2a所示, 在实线表示的子帧上可以测量到第三小小区的 DRS, 在虚线 表示的子帧上可以测量到第一小小区和第二小小区的 DRS。 并且通过测量模 块 102 分别采用至少两个所述互相独立的 RRM 测量流程对一个载波进行 RRM测量, 并分别获得至少两个 RRM测量结果, 即可以对不同小小区进行 独立的 RRM测量, 因此, 能够测量到非持续发送 DRS的邻区, 获得的准确 的邻区发现和邻区测量结果。
具体而言, 由于基站之间是有有线连接的, 这种有线连接称为 backhaul, 基站之间可以通过 backhaul相互通信,这样开启了 DRS传输的基站可以将发 送 DRS的子帧信息通过 backhaul通知 UE的服务基站, 服务基站可以根据该 子帧信息来配置相应的测量时域信息, 对于图 2a所示例子来说, 服务基站可 以将第二组测量时域信息配置为第一小小区和第二小小区发送 DRS的子帧集 合, 即图 2a中第二个时间轴上的虚线方块。
图 2b 为三个小小区发送发现参考信号以及 UE 的测量时域信息的示意 图, 图 2b中横轴代表时间轴, 三个小小区的时间轴上灰色的小方块代表有信 号传输的子帧, 如图 2b所示, 第三小小区处于打开的状态, 持续进行下行信 号的传输; 而第一小小区和第二小小区处于关闭状态, 仅仅周期性地发送一 些 DRS。 与图 2a不同的是, 图 2b中处于关闭状态的第一小小区和第二小小 区发送 DRS的时刻不同, 这样的好处是, 可以降低第一小小区和第二小小区 同时发送 DRS发送导致的互相干扰,也就是说处于关闭状态的小区在不同的 时间向所有小区发送 DRS, 干扰会比较低。 对于 RRM测量, 就需要基站给 UE配置至少 3组 RRM测量流程才能保证对以上三个小区的邻区测量的准确 性, 如图 2b的第二个时间轴上分别用实线方块、虚线方块和阴影方块表示三 组 RRM测量流程对应的三组测量子帧集合。
进一歩地, 所述至少两组测量时域信息可以采用以下四种方式中的任意 一种:
方式一、 所述基站为每个载波配置的至少两个测量子帧集合, 所述每个 测量子帧集合为一组测量时域信息。
具体地, 由于基站会为每个载波配置一个测量子帧集合
measSubframePattemConfig , 在本实施例中, 基站可以为每个载波配置多个测 量子帧集合, 例如为每个载波配置两个测量子帧集合:
measSubframePattemConfig 1禾卩 measSubframePattemConfig 2。 并^!每
measSubframePattemConfig 1作为第一组测量时域信息, 即图 2a中第二个时 间轴上的实线方格, measSubframePattemConfig 2作为第二组测量时域信息, 即图 2a中第二个时间轴上的虚线方格。
采用这种方式时, 指示第一组测量时域信息和第二组测量时域信息的方 式可以分别按照固定的周期, 在分别固定的周期中, 指出哪些子帧是测量子 帧。 例如 measSubframePatternConfigl可以是 1010101010, 代表以 10个子帧 为周期, 第 1、 3、 5、 7、 9子帧为测量的子帧, 即图 2a中第二个时间轴上的 实线方格; measSubfr纖 ePatternConfig2可以是 00000000000000000001, 代表 以 20子帧为周期, 每 20个子帧的最后一个子帧为测量的子帧, 即图 2a第二 个时间轴上的虚线方格。
方式二、 所述基站在所述为每个载波配置的测量子帧集合中划分出的至 少两个子集, 所述每个子集为一组测量时域信息。
具体地, 例如基站为某个载波配置的测量子帧集合可以配置成 1010101010, 这就代表, 以 10个子帧为周期, 第 1、 3、 5、 7、 9子帧为用来 测量的子帧(也就是所述 1010101010字符串中设为 1的子帧) , 而余下子帧 是不用来做测量的。在本实施例中, 基站可以进一歩下发信令给 UE, 该信令 例如为 "measSubframeSubset", 指示其中的 9子帧组成的子集作为第二组测 量时域信息, 即图 2a第二个时间轴上的虚线方格, 而余下的 1、 3、 5、 7子 帧组成的子集作为第一组测量时域信息, 即图 2a中第二个时间轴上的实线方 格。 或者, 基站发给 UE的子帧配置可以为 1010101020, 其中 0代表不做测 量的子帧, 1代表属于第一测量时域信息的子帧, 2代表属于第二测量时域 信息的子帧。
方式三、所述基站为每个载波配置至少两个测量间隙 gap,所述每个测量 gap 为一组测量时域信息。 具体地, 由于基站会为每个载波会配置一个测量 gap, UE只能在 gap中指定的子帧上进行测量。本实施例中, 基站可以为 UE 酉己置多个测量 gap, 具体可以通过测量 ga 设置 ( Measurement gap configuration) 这个参数来配置。 该参数是针对于异频测量设置的, 由于 UE 需要对于多个载波进行 RRM测量, UE本身也会在某个载波工作(也就是说, UE在某个载波和服务小区保持连接) 。 UE如果测量的载波与当前工作的载 频是相同的, 则称为同频测量; UE如果测量的载波与当前的载波不相同, 则 成为异频测量。 UE在异频测量时, 往往需要中断在原来载频的工作, 然后去 接收其他载频的信号并进行测量。此处, 中断的时间就是所述的 gap。在 LTE 中, gap的出现是周期性的, 例如可以规定 40ms或 80ms有一个 gap, 每个 gap的时间长度是 6ms。测量 gap设置这个参数就是设置 gap的周期和具体的 位置。
例如配置 gapl , gap2, 且 gapl , gap2表示独立的两组子帧集合, 每个 gap作为一组测量时域信息。其中 gapl与 gap2的周期、偏置和持续时间均可 以不相同, 当然也可以部分相同。 例如 gapl的周期可以是 40ms, 而 gap2的 周期可以是 80ms (甚至可以是 480ms) ; Gapl的持续时间可以为 6个连续 的子帧, 而 gap2的持续时间可以为连续的 20个子帧。 在这种情况下, 基站 需要将每个 gap所对应的周期, 偏置, 和持续时间分别发送给 UE。
方式四、所述基站在所述测量 gap指示的子帧中划分出的至少两个子 gap
( sub-gap) , 所述每个子 gap为一组测量时域信息。
具体地, gap可以设置为每隔 40或 80个子帧就有 6个子帧设为 gap。 例如, 可以设置周期为 40子帧, 并且这个 gap指示的第一组测量子帧是 1-6 子帧; 第二组测量子帧就是 41-46子帧; 第三组测量子帧就是 81-86子帧。那 么在本实施例中, 可以设置为: 这个 gap的每五组测量子帧中的第一组, 也 就是子帧 1-6为第二组测量时域信息, 其余的测量子帧为第一组测量时域信 息。
进一歩地, 本实施例中, 针对每个载波 RRM测量流程的配置信息包括 一组测量时域信息和对应的测量参数信息, 其中每一组测量时域信息对应的 测量参数信息包括以下参数中的至少一个: 测量带宽、 可能测量到的小区名 单、 小区黑名单、 事件触发上报的门限、 上报周期、 上报测量量、 上报事件 驱动量、 上报的最大小区数量、 层三滤波器参数设置、 CRS天线端口 1是否 存在。
下面对配置参数进行详细说明。
测量带宽 (allowed measurement bandwidth) , 表示用于 RRM测量的带 宽是多少。 例如可以设置对于一个 RRM测量流程, 测量的带宽为 15个物理 资源块(Physical Resource Block, 简称: PRB) , 而对于另一个 RRM测量流 程, 测量的带宽为 50个 PRB。
其中, 设置测量带宽的意义在于: UE在进行 RRM测量的时候是通过周 围小区发送的下行参考信号来进行测量的。 周围小区发送的信号往往占据一 个较大的带宽, 例如使用了 20M带宽, 但是 UE的测量往往并不需要使用全 带宽的下行参考信号, 所以可以指定 UE具体使用多少带宽来完成测量。
可能测量到的小区名单(NeighCellList) , 可以针对每个 RRM测量流程 分别设置对应的可能测量到的小区名单, 设置可能测量到的小区名单的意义 在于: UE会去测量多个载波, 在每个载波上, 都会有多个小区在工作。 所以 UE对某个载波进行测量时, 可能会发现多个小区, 并且对于每个小区分别进 行 RRM测量。 配置 NeighCellList就是告知 UE, 周围有哪些小区, 这些小区 都是在 UE进行邻区发现与测量的时候可能发现的小区。
具体配置时, 例如可以针对一个 RRM测量流程, 将可能测量到的小区 名单设置为 10、 18、 90, 针对另一个 RRM测量流程, 将可能测量到的小区 名单设置为 45、 56、 78。
小区黑名单(blackcell) , 可以针对每个 RRM测量流程分别设置对应的 小区黑名单, 配置小区黑名单的意义在于: 处于运营的目的, 某些周围小区 是不允许某些 UE接入的, 例如某些小区是私有的小区, 不允许非认证的用 户接入。 所以在测量的时候就没有必要上报对于这些小区的测量结果。 小区 黑名单就是告知 UE在这个载波上不需要上报的小区名单。 。 具体配置时, 例如可以针对一个 RRM测量流程, 将可能测量到的小区名单设置为 23、 24、 132, 针对另一个 RRM测量流程, 将可能测量到的小区名单设置为 35、 67、 132。
事件触发上报的门限, 是值达到预设的条件(事件触发上报的门限)时,
UE将 RRM测量的结果上报给网络侧。 该参数可以包括多个事件的触发上报 门限, 并且也可以为一个事件设置多个门限, 针对每个 RRM测量流程也可 以分别独立地设置。 其中, 在 LTE协议中规定了一些列的预设条件, 分别为 EventAl, EventA2, …, EventA6, 各个事件的意义如下: EventAl指的是 UE 保持连接的小区 (serving cell) 的信号质量超过了一定的门限; EventA2指的 是 UE保持连接的小区(serving cell)的信号质量低过了一定的门限; EventA3 指的是邻居小区的信号质量超过了 UE的 PCdl达到了一个门限, 这里 UE的 PCell指的是 UE可能会在多个载波同时工作,其中一个载波称为 UE的 PCell (Primary Cell) , 其他的载波称为 UE的 SCell ( Secondary Cell ) ; EventA4 指的是,邻居小区的信号质量超过了一个门限; EventA5指的是 UE保持连接 的主小区 (PCell) 的接收质量低于门限 1, 而邻居小区的接收质量高于门限 2; EventA6指的是邻居小区的信号质量超过了 UE的 SCell达到了一个门限。
具体配置时, 例如对于一个 RRM测量流程设置 {EventAl门限, EventA2 门限, EventA3门限, EventA4门限, EventA5门限 1, EventA5门限 2, EventA6 门限},对于另一个 RRM测量流程设置 { EventAl门限, EventA2门限, EventA3 门限 }。
上报周期 (Report Interval) , 可以针对每个 RRM测量流程分别设置对 应的上报周期。例如可以针对一个 RRM测量流程,将上报周期设置为 320ms, 针对另一个 RRM测量流程, 将上报周期设置为 640ms。
上报测量量, 可以设置为仅上报 RSRP或仅上报 RSRQ, 或者两者都上 报, 且可以针对每个 RRM测量流程分别设置对应的上报测量量。 例如可以 针对一个 RRM测量流程, 设置为上报 RSRP; 针对另一个 RRM测量流程, 设置为上报 RSRQ。
上报事件驱动量, 可以设置为 RSRP或 RSRQ, 该参数用于指示 UE, 对 于事件触发上报, 触发的条件是按照 RSRP来还是 RSRQ来。 例如 A1事件 (EventAl ) ,说的是服务小区的信号质量超过一定门限就进行触发,是 RSRP 高于门限还是 RSRQ高于门限。 也就是说上述的事件 A1-A6, 可以是按照 RSRP来驱动的, 也可以是按照 RSRQ来驱动的。可以针对每个 RRM测量流 程分别设置对应的上报事件驱动量。
上报的最大小区数量(maximal cell to report) , 可以针对每个 RRM测量 流程分别设置, 例如可以针对一个 RRM测量流程, 将上报的最大小区数量 设置为 3, 针对另一个 RRM测量流程, 将上报的最大小区数量设置为 5。
层三滤波器参数(FilterCoefficient) , 可以针对每个 RRM测量流程分别 设置, 例如可以针对一个 RRM测量流程, 将层三滤波器参数设置为 0.7, 针 对另一个 RRM测量流程, 将层三滤波器参数设置为 0.9。 这个参数的意义与 UE的具体测量行为有关, UE的测量会首先得到多个层一(layerl )测量结果, 然后 UE会将层一测量结果进行平均 (或滤波) 得到滤波后结果; 然后 UE 的层一 (L1 )会将滤波后的结果按照一定的速率上报给 UE的高层,例如 200ms 上报一次, 或者 480ms上报一次等。 UE的高层会对 L1上报的结果进行高层 滤波, 在 LTE中, 这样的滤波也称为层三滤波(Layer3 filtering) 。 层三滤波 的滤波器系数是需要设定的, 这里的 FilterCoefficient就按照配置的数值来进 行设置。
CRS天线端口 1是否存在(参数名称例如为 presenseAntennaPortl ) , 可 以设置为是或否。 例如可以设置对于一个 RRM测量流程, 将该参数设置为 "是" , 而对于另一个 RRM测量流程, 将该参数设置为 "否" 。 设置该参数的意义在于: UE进行 RRM测量是基于下行参考信号的, 在 目前的 LTE系统中,UE主要是根据周围基站下发的 CRS来进行测量的。 LTE 中的 CRS可能会采用天线端口 0-3发送。 每个基站都会发送 CRS, 并且至少 会在天线端口 0 (antenna port 0) 发送 CRS。 而至于天线端口 1,2,3是否发送 CRS是不确定的。 所以 UE在进行 RRM测量的时候会至少通过天线端口 0 发送的 CRS来进行。 这里设置 "presenseAntennaPortl "就是告诉 UE, 是不 是除了天线端口 0之外, 还可以使用天线端口 1来一起进行 RRM测量。
测量参数信息还可以包括 OffsetFreq,该参数表示针对这个载波测量得到 的 RSRP或 RSRQ的补偿值。 例如可以设置对于一个 RRM测量流程, 将该 参数设置为 0dB, 而对于另一个 RRM测量流程, 将该参数设置为 5dB。
UE在接收到上述 RRM测量流程的配置信息之后, 根据每个 RRM测量 流程分别在测量时域信息所确定的子帧上, 根据对应的按照相应的测量参数 信息, 来进行 RRM测量与上报。
本实施例的 UE, 通过接收基站发送的至少两个互相独立的 RRM测量流 程的配置信息, 并通过采用至少两个所述互相独立的 RRM测量流程对一个 载波进行 RRM测量, 分别获得至少两个 RRM测量结果, 并将所述 RRM测 量结果上报给所述基站; 由于所述至少两个互相独立的 RRM测量流程可以 针对不同的邻区来配置, 因此每个 RRM测量流程对应的测量时域信息与待 测邻区发送 RRM测量参考信号的时域信息相匹配, 因此能够测量到非持续 发送 RRM测量参考信号的邻区, 获得的准确的邻区发现和邻区测量结果。

将至少两个所述 RRM测量结果进行加权平均之后上报给所述基站。 具体地, 以图 2a所示例子进行描述, 设实线表示的子帧用于对应于第一 RRM测量流程 1, 虚线表示的子帧对应于第二 RRM测量流程。 其中由于第 三小小区一直是打开的,所以 UE在执行第一 RRM测量流程时会发现第三小 小区的存在, 并且对其进行 RRM测量; 同时 UE在执行第二 RRM测量流程 时也会发现第三小小区, 并且对其进行 RRM测量。 由于不同的测量子帧中 的干扰水平是不同的,例如图 2a中,在第一 RRM测量流程所对应的子帧上, 第一小小区和第二小小区都没有信号传输,所以第三小小区的 DRS传输不会 受到这两个小区的干扰, 但是在第二 RRM测量流程所对应的子帧上, 第三 小小区的传输会受到第一小小区和第二小小区的干扰, 所以, 两个 RRM测 量流程所测量到的结果是不同的。
这时, 针对第三小小区的测量结果, UE可以有三种处理方法:
方法一、 UE将两个流程中得到第三小小区的两个测量结果都进行上报。 采用方式一的好处在于, 网络侧可以获得两个测量结果; 一旦处于关闭状态 的小区转变为开启状态后, 对于目前处于开启状态的小区的接收质量的存在 影响。 这个方案的好处在于, 通过上报两个结果, 可以帮助网络侧判断, 如 果打开目前处于关闭状态的小区之后,对于已经打开的小区带来怎样的影响, 从而可以帮助网络侧来判断是否去打开一个关闭状态的小区。例如第一 RRM 测量流程的测量结果反应的都是第一, 第二小小区关闭状态下的第三小区的 接收信号质量, 而第二 RRM测量流程的结果则反应了如果第一, 第二小小 区打开之后, 第三小小区的接收信号质量。 通过这两组结果, 网络侧可以判 断打开第一, 第二小小区是否有好处。
方法二、 UE可以根据基站的指示, 只上报第一 RRM测量流程所得到的 测量结果。 采用方式二的好处在于, 上报的信息量较少, 可以节省空口资源。
方法三、 UE可以根据基站的指示, 将两个流程的结合后的结果上报。例 如, UE可以先对两个所述 RRM测量结果进行加权平均之后上报给所述基站, 例如采用 M=0.9M1 + 0.1M2, 其中 M为最终上报的结果, Ml为第一 RRM 测量流程所得到的测量结果, M2为第二 RRM测量流程所得到的测量结果。
其中,基站可以事先配置好该 UE对第三小小区的 RRM测量结果的上报 方式, 也可以实时地指示 UE采用何种方式进行上报。
在另一个实施例中, 所述测量参数信息包括可能测量到的小区名单; 则所述发送模块 103具体用于:
UE仅将所述测量得到的 RRM测量结果中属于所述可能测量到的小区名 单中的小区的 RRM测量结果上报给所述基站。 具体实现时, 基站给 UE下发的 RRM测量流程的配置信息中, 包括可能 测量到的小区名单(NeighCellList) 。 本实施例中, 可选地, 基站在预先配置 了多个 RRM测量流程之后, 可以将其中的一个或几个设置为对于小区
NeighCellList之外的小区, 即使发现了, 也不对其来进行测量; 或者, 即使 测量 NeighCellList之外的小区, 也不将这些小区的测量结果进行上报。 以图 2a的例子为例, 第二 RRM测量流程 (虚线表示的子帧) 可以发现第一小小 区、 第二小小区和第三小小区, 按照本实施例的方法, 可以设置可能测量到 的小区名单为第一小小区和第二小小区, 即规定目标小区仅为第一小小区和 第二小小区, 那么在第二 RRM测量流程对应的测量中, 即使 UE发现了第三 小小区也不进行测量; 或者可以规定对第三小小区的测量结果不进行上报。
图 3为本发明提供的基站实施例一的结构示意图, 如图 3所示, 本实 施例的基站 300可以包括: 配置模块 301、 发送模块 302和接收模块 303, 其中,
配置模块 301, 用于为一个载波配置至少两个互相独立的无线资源管理 RRM测量流程, 每个所述 RRM测量流程的配置信息包括一组测量时域信息 和对应的测量参数信息;
发送模块 302, 用于向 UE发送所述至少两个互相独立的 RRM测量流程 的配置信息, 以使所述 UE采用所述至少两个互相独立的无线资源管理 RRM 测量流程对每个载波进行 RRM测量;
接收模块 303, 用于接收所述 UE上报的 RRM测量结果。
进一歩具体地, 所述配置模块 301, 具体用于根据相邻基站发送发现参 考信号的时域信息为每个载波配置至少两组测量时域信息, 并分别为每组测 量时域信息配置对应的测量参数信息。
而现有的 RRM测量过程中,基站通常只为载波配置一个 RRM测量流程, 即每个载波对应一组测量时域信息及其对应的测量参数信息。 下面以小小区 的网络为例来说明本实施例的 UE如何进行现有技术的 RRM无法进行的邻区 测量。 同样采用图 2a所示的例子, 假设网络中有三个小小区, 分别是第一小 小区、第二小小区和第三小小区,如图 2a所示,第三小小区处于打开的状态, 持续进行下行信号的传输; 而第一小小区和第二小小区处于关闭状态, 仅仅 周期性地发送一些 DRS。如果采用现有技术进行小区测量与发现,基站给 UE 配置一组测量子帧作为测量时域信息, 如图 2a中实线表示的子帧, 让 UE在 这组测量子帧上进行 RRM测量,那么,该 UE能够测量到第三小小区的 DRS, 但不一定能测量到第二小小区或第一小小区的 DRS , 因此按照现有技术的 RRM测量进行测量结果间的平均与滤波, 会造成测量结果的偏差。
而在本实施例中, 基站通过配置至少两组测量时域信息(如图 2a中一组 实线表示的子帧和一组虚线表示的子帧) 和每组所述测量时域信息对应的测 量参数信息, 即可以针对不同的小小区配置不同的测量时域信息, 使每组测 量时域信息分别与一个小小区发送 DRS的周期相匹配, 如图 2a所示, 在实 线表示的子帧上可以测量到第三小小区的 DRS, 在虚线表示的子帧上可以测 量到第一小小区和第二小小区的 DRS。 并且通过指示 UE分别采用至少两个 所述互相独立的 RRM测量流程对一个载波进行 RRM测量,并分别获得至少 两个 RRM测量结果, 即可以对不同小小区进行独立的 RRM测量, 因此, 能 够测量到非持续发送 DRS的邻区, 获得准确的邻区发现和邻区测量结果。
具体而言, 由于基站之间可以通过 backhaul相互通信, 开启了 DRS传输 的基站可以将发送 DRS的子帧信息通过 backhaul通知 UE的服务基站, 服务 基站可以根据该子帧信息来配置相应的测量时域信息,对于图 2a所示例子来 说, 服务基站可以将第二组测量时域信息配置为第一小小区和第二小小区发 送 DRS的子帧集合, 即图 2a中第二个时间轴上的虚线方块, 即服务基站为 UE配置的测量时域信息能够与第一小小区和第二小小区发送 DRS的子帧相 匹配, 从而保证 UE能够测量到第一小小区和第二小小区的邻区信息, 并获 得准确测量结果。
具体实现时, 所述配置模块 301具体用于:
为每个载波配置至少两个测量子帧集合, 将所述每个测量子帧集合作为 一组测量时域信息; 或者
在所述测量子帧集合中划分出的至少两个子集, 将所述每个子集作为一 组测量时域信息; 或者
为每个载波配置至少两个测量间隙 gap,将所述每个测量 gap为一组测量 时域信息; 或者
在所述测量 gap中划分出的至少两个子 gap,将所述每个子 gap作为一组 测量时域信息。 具体的实现过程可以参见 UE实施例一中关于所述至少两组测量时域信 息的描述。
进一歩地, 所述配置信息包括以下参数中的至少一个: 测量带宽、 可能 测量到的小区名单、 小区黑名单、 事件触发上报的门限、 上报周期、 上报测 量量、 上报事件驱动量、 上报的最大小区数量、 层三滤波器参数设置、 CRS 天线端口 1是否存在。
其中对于配置参数的详细说明可以参见 UE实施例一中关于配置参数的 描述。
进一歩地, 所述接收模块 303具体用于:
接收所述 UE分别上报的至少两个所述 RRM测量结果; 或者
接收所述 UE在至少两个所述 RRM测量结果中选择的部分所述 RRM测 量结果; 或者
接收所述 UE将至少两个所述 RRM测量结果进行结合之后的 RRM测量 结果。
在一种实现方式中, 所述接收模块 303具体用于:
接收所述 UE将至少两个所述 RRM测量结果进行加权平均之后的 RRM 具体地, 以图 2a所示例子进行描述, 设实线表示的子帧用于对应于第一 RRM测量流程 1, 虚线表示的子帧对应于第二 RRM测量流程。 其中由于第 三小小区一直是打开的,所以 UE在执行第一 RRM测量流程时会发现第三小 小区的存在, 并且对其进行 RRM测量; 同时 UE在执行第二 RRM测量流程 时也会发现第三小小区, 并且对其进行 RRM测量。 由于不同的测量子帧中 的干扰水平是不同的,例如图 2a中,在第一 RRM测量流程所对应的子帧上, 第一小小区和第二小小区都没有信号传输,所以第三小小区的 DRS传输不会 受到这两个小区的干扰, 但是在第二 RRM测量流程所对应的子帧上, 第三 小小区的传输会受到第一小小区和第二小小区的干扰, 所以, 两个 RRM测 量流程所测量到的结果是不同的。
这时, 针对第三小小区的测量结果, 基站可以指示 UE采用以下三种处 理方法中的任意一种进行结果上报:
方式一、 指示 UE将两个流程中得到第三小小区的两个测量结果都进行 上报。
方式二、指示 UE可以根据基站的指示, 只上报第一 RRM测量流程所得
、方式三、 指示 UE可以根据基站的指示, 将两个流程的结合后的结果上 报。 例如, UE可以先对两个所述 RRM测量结果进行加权平均之后上报给所 述基站, 例如采用 M=0.9M1 + 0.1M2, 其中 M为最终上报的结果, Ml为第 一 RRM测量流程所得到的测量结果, M2为第二 RRM测量流程所得到的测 其中,基站可以事先配置好该 UE对第三小小区的 RRM测量结果的上报 方式, 也可以实时地指示 UE采用何种方式进行上报。
相应的, 接收模块 303可能接收三种方式上报的 RRM测量结果。
可选地, 在一种可能的实现方式中, 所述测量参数信息包括可能测量到 的小区名单;
所述接收模块 303具体用于:
接收所述 UE仅上报的在所述测量得到的 RRM测量结果中属于所述可能 测量到的小区名单中的小区的 RRM测量结果。
具体实现时, 基站给 UE下发的 RRM测量流程的配置信息中, 包括可能 测量到的小区名单(NeighCellList) 。 本实施例中, 可选地, 基站在预先配置 了多个 RRM 测量流程之后, 可以将其中的一个或几个设置为对于小区 NeighCellList之外的小区, 即使发现了, 也不对其来进行测量; 或者, 即使 测量 NeighCellList之外的小区, 也不将这些小区的测量结果进行上报。 仍然 以图 2a的例子为例, 第二 RRM测量流程 (虚线表示的子帧) 可以发现第一 小小区、 第二小小区和第三小小区, 按照本实施例的方法, 可以设置可能测 量到的小区名单为第一小小区和第二小小区, 即规定目标小区仅为第一小小 区和第二小小区, 那么在第二 RRM测量流程对应的测量中, 即使 UE发现了 第三小小区也不进行测量; 或者可以规定对第三小小区的测量结果不进行上 报。
本实施例的基站, 通过为载波配置至少两个互相独立的无线资源管理 RRM测量流程, 每个所述 RRM测量流程的配置信息包括一组测量时域信息 和对应的测量参数信息,并向 UE发送所述至少两个互相独立的 RRM测量流 程的配置信息, 以使所述 UE 采用所述至少两个互相独立的无线资源管理 RRM测量流程对每个载波进行 RRM测量, 通过采用至少两个所述互相独立 的 RRM测量流程对一个载波进行 RRM测量, 再接收所述 UE上报的 RRM 测量结果; 由于所述至少两个互相独立的 RRM测量流程可以针对不同的邻 区来配置, 因此每个 RRM 测量流程对应的测量时域信息与待测邻区发送 RRM测量参考信号的时域信息相匹配, 因此能够测量到非持续发送 RRM测 量参考信号的邻区, 获得的准确的邻区发现和邻区测量结果。

图 6为本发明提供的邻区测量方法实施例一的流程图, 本实施例的方法 的执行主体为 UE,可以由图 1或图 4所示实施例的 UE来执行。如图 6所示, 本实施例的方法可以包括:
歩骤 601、 UE接收基站发送的至少两个互相独立的 RRM测量流程的配 置信息, 所述 RRM测量流程是所述基站根据待测邻区的信息配置的。
具体地, 每个所述 RRM测量流程的配置信息可以包括一组测量时域信 息和对应的测量参数信息。
则歩骤 601具体为: 所述 UE接收基站发送的至少两组测量时域信息和 每组所述测量时域信息对应的测量参数信息。
歩骤 602、 所述 UE采用至少两个所述互相独立的 RRM测量流程对一个 载波进行 RRM测量, 并分别获得至少两个 RRM测量结果。
歩骤 603、 所述 UE将所述 RRM测量结果上报给所述基站。
现有技术的 RRM测量过程中,基站通常只为载波配置一个 RRM测量流 程, 即每个载波对应一组测量时域信息及其对应的测量参数信息。 下面以小 小区的网络为例来说明本实施例的 UE如何进行现有技术的 RRM无法进行的 邻区测量。 同样采用图 2a所示的例子, 假设网络中有三个小小区, 分别是第 一小小区、 第二小小区和第三小小区, 如图 2a所示, 第三小小区处于打开的 状态, 持续进行下行信号的传输; 而第一小小区和第二小小区处于关闭状态, 仅仅周期性地发送一些 DRS。 如果采用现有技术进行小区测量与发现, 基站 给 UE配置一组测量子帧作为测量时域信息, 如图 2a中实线表示的子帧, 让 UE在这组测量子帧上进行 RRM测量, 那么, 该 UE能够测量到第三小小区 的 DRS, 但不一定能测量到第二小小区或第一小小区的 DRS, 因此按照现有 技术的 RRM测量进行测量结果间的平均与滤波, 会造成测量结果的偏差。
而在本实施例中, 基站通过配置至少两组测量时域信息(如图 2a中一组 实线表示的子帧和一组虚线表示的子帧) 和每组所述测量时域信息对应的测 量参数信息, 即可以针对不同的小小区配置不同的测量时域信息, 使每组测 量时域信息分别与一个小小区发送 DRS的周期相匹配, 如图 2a所示, 在实 线表示的子帧上可以测量到第三小小区的 DRS, 在虚线表示的子帧上可以测 量到第一小小区和第二小小区的 DRS。 并且通过指示 UE分别采用至少两个 所述互相独立的 RRM测量流程对一个载波进行 RRM测量,并分别获得至少 两个 RRM测量结果, 即可以对不同小小区进行独立的 RRM测量, 因此, 能 够测量到非持续发送 DRS的邻区, 获得准确的邻区发现和邻区测量结果。
具体而言, 由于基站之间可以通过 backhaul相互通信, 开启了 DRS传输 的基站可以将发送 DRS的子帧信息通过 backhaul通知 UE的服务基站, 服务 基站可以根据该子帧信息来配置相应的测量时域信息,对于图 2a所示例子来 说, 服务基站可以将第二组测量时域信息配置为第一小小区和第二小小区发 送 DRS的子帧集合, 即图 2a中第二个时间轴上的虚线方块, 即服务基站为 UE配置的测量时域信息能够与第一小小区和第二小小区发送 DRS的子帧相 匹配, 从而保证 UE在歩骤 602中能够测量到第一小小区和第二小小区的邻 区信息, 并获得准确测量结果。
具体实现时, 所述至少两组测量时域信息可以包括:
所述基站为每个载波配置的至少两个测量子帧集合, 所述每个测量子帧 集合为一组测量时域信息; 或者
所述基站在所述为每个载波配置的测量子帧集合中划分出的至少两个子 集, 所述每个子集为一组测量时域信息; 或者
所述基站为每个载波配置至少两个测量间隙 gap,所述每个测量 gap为一 组测量时域信息; 或者
所述基站在所述测量 gap中划分出的至少两个子 gap,所述每个子 gap为 一组测量时域信息。
具体的实现过程可以参见 UE实施例一中关于所述至少两组测量时域信 息的描述, 此处不再赘述。
进一歩地, 所述测量参数信息包括以下参数中的至少一个: 测量带宽、 可能测量到的小区名单、 小区黑名单、 事件触发上报的门限、 上报周期、 上 报测量量、 上报事件驱动量、 上报的最大小区数量、 层三滤波器参数设置、 CRS天线端口 1是否存在。
其中对于配置参数的详细说明可以参见 UE实施例一中关于配置参数的 描述。
进一歩地, 歩骤 603中所述 UE将所述 RRM测量结果上报给所述基站, 可以包括:
所述 UE分别将至少两个所述 RRM测量结果上报给所述基站; 或者 所述 UE在至少两个所述 RRM测量结果中选择一个所述 RRM测量结果 上报给所述基站; 或者
所述 UE将至少两个所述 RRM测量结果进行结合之后上报给所述基站。 在一种实现方式中,所述 UE将至少两个所述 RRM结果进行结合之后上 报给所述基站, 可以包括:
所述 UE将至少两个所述 RRM测量结果进行加权平均之后上报给所述基 站。
具体地, 以图 2a所示例子进行描述, 设实线表示的子帧用于对应于第一
RRM测量流程 1, 虚线表示的子帧对应于第二 RRM测量流程。 其中由于第 三小小区一直是打开的,所以 UE在执行第一 RRM测量流程时会发现第三小 小区的存在, 并且对其进行 RRM测量; 同时 UE在执行第二 RRM测量流程 时也会发现第三小小区, 并且对其进行 RRM测量。 由于不同的测量子帧中 的干扰水平是不同的,例如图 2a中,在第一 RRM测量流程所对应的子帧上, 第一小小区和第二小小区都没有信号传输,所以第三小小区的 DRS传输不会 受到这两个小区的干扰, 但是在第二 RRM测量流程所对应的子帧上, 第三 小小区的传输会受到第一小小区和第二小小区的干扰, 所以, 两个 RRM测 量流程所测量到的结果是不同的。
这时, 针对第三小小区的测量结果, 基站可以指示 UE采用以下三种处 理方法中的任意一种进行结果上报:
方式一、 指示 UE将两个流程中得到第三小小区的两个测量结果都进行 上报。
方式二、指示 UE可以根据基站的指示, 只上报第一 RRM测量流程所得 方式三、 指示 UE可以根据基站的指示, 将两个流程的结合后的结果上 报。 例如, UE可以先对两个所述 RRM测量结果进行加权平均之后上报给所 述基站, 例如采用 M=0.9M1 + 0.1M2, 其中 M为最终上报的结果, Ml为第 一 RRM测量流程所得到的测量结果, M2为第二 RRM测量流程所得到的测 量结果。 其中,基站可以事先配置好该 UE对第三小小区的 RRM测量结果的上报 方式, 也可以实时地指示 UE采用何种方式进行上报。
可选地, 在另一种可能的实现方式中, 所述测量参数信息包括可能测量 到的小区名单;
则歩骤 603可以为:所述 UE仅上报的在所述测量得到的 RRM测量结果 中属于所述可能测量到的小区名单中的小区的 RRM测量结果。
具体实现时, 基站给 UE下发的 RRM测量流程的配置信息中, 包括可能 测量到的小区名单 (NeighCellList) 。 可选地, 基站在预先配置了多个 RRM 测量流程之后, 可以将其中的一个或几个设置为对于小区 NeighCellList之外 的小区, 即使发现了, 也不对其来进行测量; 或者, 即使测量 NeighCellList 之外的小区,也不将这些小区的测量结果进行上报。仍然以图 2a的例子为例, 第二 RRM测量流程 (虚线表示的子帧) 可以发现第一小小区、 第二小小区 和第三小小区, 按照本实施例的方法, 可以设置可能测量到的小区名单为第 一小小区和第二小小区, 即规定目标小区仅为第一小小区和第二小小区, 那 么在第二 RRM测量流程对应的测量中,即使 UE发现了第三小小区也不进行 测量; 或者可以规定对第三小小区的测量结果不进行上报。
本实施例, UE通过接收基站发送的至少两个互相独立的 RRM测量流程 的配置信息, 并通过采用至少两个所述互相独立的 RRM测量流程对一个载 波进行 RRM测量, 分别获得至少两个 RRM测量结果, 并将所述 RRM测量 结果上报给所述基站; 由于所述至少两个互相独立的 RRM测量流程可以针 对不同的邻区来配置, 因此每个 RRM测量流程对应的测量时域信息与待测 邻区发送 RRM测量参考信号的时域信息相匹配, 因此能够测量到非持续发 送 RRM测量参考信号的邻区, 获得的准确的邻区发现和邻区测量结果。
图 7为本发明提供的邻区测量方法实施例二的流程图, 本实施例的方法 的执行主体为基站, 可以由图 3或图 5所示实施例的基站来执行。 如图 7所 示, 本实施例的方法可以包括:
歩骤 701、 基站为一个载波配置至少两个互相独立的无线资源管理 RRM 测量流程, 每个所述 RRM测量流程的配置信息包括一组测量时域信息和对 应的测量参数信息。

歩骤 702、 所述基站向 UE发送所述至少两个互相独立的 RRM测量流程 的配置信息, 以使所述 UE采用所述至少两个互相独立的无线资源管理 RRM 测量流程对每个载波进行 RRM测量。
歩骤 703、 所述基站接收所述 UE上报的 RRM测量结果。
相比于现有技术的 RRM测量, 本实施例中由于基站为每个载波配置多 个互相独立的 RRM测量流程, 并发送给 UE, 使 UE采用所述至少两个互相 独立的 RRM测量流程对每个载波进行 RRM测量,从而对不同的基站采用不 同的 RRM测量流程进行测量, 因此能够测量到非持续发送 DRS信号的的邻 区。 下面具体说明该方法的原理。
现有技术的 RRM测量过程中,基站通常只为载波配置一个 RRM测量流 程, 即每个载波对应一组测量时域信息及其对应的测量参数信息。 下面以小 小区的网络为例来说明本实施例的 UE如何进行现有技术的 RRM无法进行的 邻区测量。 同样采用图 2a所示的例子, 假设网络中有三个小小区, 分别是第 一小小区、 第二小小区和第三小小区, 如图 2a所示, 第三小小区处于打开的 状态, 持续进行下行信号的传输; 而第一小小区和第二小小区处于关闭状态, 仅仅周期性地发送一些 DRS。 如果采用现有技术进行小区测量与发现, 基站 给 UE配置一组测量子帧作为测量时域信息, 如图 2a中实线表示的子帧, 让 UE在这组测量子帧上进行 RRM测量, 那么, 该 UE能够测量到第三小小区 的 DRS, 但不一定能测量到第二小小区或第一小小区的 DRS, 因此按照现有 技术的 RRM测量进行测量结果间的平均与滤波, 会造成测量结果的偏差。
而在本实施例中, 基站通过配置至少两组测量时域信息(如图 2a中一组 实线表示的子帧和一组虚线表示的子帧) 和每组所述测量时域信息对应的测 量参数信息, 即可以针对不同的小小区配置不同的测量时域信息, 使每组测 量时域信息分别与一个小小区发送 DRS的周期相匹配, 如图 2a所示, 在实 线表示的子帧上可以测量到第三小小区的 DRS, 在虚线表示的子帧上可以测 量到第一小小区和第二小小区的 DRS。 并且通过指示 UE分别采用至少两个 所述互相独立的 RRM测量流程对一个载波进行 RRM测量,并分别获得至少 两个 RRM测量结果, 即可以对不同小小区进行独立的 RRM测量, 因此, 能 够测量到非持续发送 DRS的邻区, 获得准确的邻区发现和邻区测量结果。
具体而言, 由于基站之间可以通过 backhaul相互通信, 开启了 DRS传输 的基站可以将发送 DRS的子帧信息通过 backhaul通知 UE的服务基站, 服务 基站可以根据该子帧信息来配置相应的测量时域信息,对于图 2a所示例子来 说, 服务基站可以将第二组测量时域信息配置为第一小小区和第二小小区发 送 DRS的子帧集合, 即图 2a中第二个时间轴上的虚线方块, 即服务基站为 UE配置的测量时域信息能够与第一小小区和第二小小区发送 DRS的子帧相 匹配, 从而保证 UE在歩骤 602中能够测量到第一小小区和第二小小区的邻 区信息, 并获得准确测量结果。
具体实现时, 所述基站根据相邻基站发送的发现参考信号为每个载波配 置至少两组测量时域信息, 可以包括:
所述基站为每个载波配置至少两个测量子帧集合, 将所述每个测量子帧 集合作为一组测量时域信息; 或者
所述基站在所述测量子帧集合中划分出的至少两个子集, 将所述每个子 集作为一组测量时域信息; 或者
所述基站为每个载波配置至少两个测量间隙 gap, 将所述每个测量 gap 为一组测量时域信息; 或者
所述基站在所述测量 gap中划分出的至少两个子 gap, 将所述每个子 gap 作为一组测量时域信息。
具体的实现过程可以参见 UE实施例一中关于所述至少两组测量时域信 息的描述, 此处不再赘述。
进一歩地, 所述配置信息包括以下参数中的至少一个: 测量带宽、 可能 测量到的小区名单、 小区黑名单、 事件触发上报的门限、 上报周期、 上报测 量量、 上报事件驱动量、 上报的最大小区数量、 层三滤波器参数设置、 CRS 天线端口 1是否存在。
其中对于配置参数的详细说明可以参见 UE实施例一中关于配置参数的 描述。
进一歩地, 歩骤 703中所述基站接收所述 UE上报的 RRM测量结果, 可 以包括: 所述基站接收所述 UE分别上报的至少两个所述 RRM测量结果; 或者 所述基站接收所述 UE在至少两个所述 RRM测量结果中选择的部分所述 RRM测量结果; 或者
所述基站接收所述 UE将至少两个所述 RRM测量结果进行结合之后的 RRM测量结果。
在一种实现方式中,所述基站接收所述 UE将至少两个所述 RRM测量结 果进行结合之后的 RRM测量结果, 可以包括:
所述基站接收所述 UE将至少两个所述 RRM测量结果进行加权平均之后 的 RRM测量结果。
具体地, 以图 2a所示例子进行描述, 设实线表示的子帧用于对应于第一
RRM测量流程 1, 虚线表示的子帧对应于第二 RRM测量流程。 其中由于第 三小小区一直是打开的,所以 UE在执行第一 RRM测量流程时会发现第三小 小区的存在, 并且对其进行 RRM测量; 同时 UE在执行第二 RRM测量流程 时也会发现第三小小区, 并且对其进行 RRM测量。 由于不同的测量子帧中 的干扰水平是不同的,例如图 2a中,在第一 RRM测量流程所对应的子帧上, 第一小小区和第二小小区都没有信号传输,所以第三小小区的 DRS传输不会 受到这两个小区的干扰, 但是在第二 RRM测量流程所对应的子帧上, 第三 小小区的传输会受到第一小小区和第二小小区的干扰, 所以, 两个 RRM测 量流程所测量到的结果是不同的。
这时, 针对第三小小区的测量结果, 基站可以指示 UE采用以下三种处 理方法中的任意一种进行结果上报:
方式一、 指示 UE将两个流程中得到第三小小区的两个测量结果都进行 上报。
方式二、指示 UE可以根据基站的指示, 只上报第一 RRM测量流程所得 方式三、 指示 UE可以根据基站的指示, 将两个流程的结合后的结果上 报。 例如, UE可以先对两个所述 RRM测量结果进行加权平均之后上报给所 述基站, 例如采用 M=0.9M1 + 0.1M2, 其中 M为最终上报的结果, Ml为第 一 RRM测量流程所得到的测量结果, M2为第二 RRM测量流程所得到的测 量结果。 其中,基站可以事先配置好该 UE对第三小小区的 RRM测量结果的上报 方式, 也可以实时地指示 UE采用何种方式进行上报。
可选地, 在另一种可能的实现方式中, 所述测量参数信息包括可能测量 到的小区名单;
则歩骤 703可以为:
所述基站接收所述 UE仅上报的在所述测量得到的 RRM测量结果中属于 所述可能测量到的小区名单中的小区的 RRM测量结果。
具体实现时, 基站给 UE下发的 RRM测量流程的配置信息中, 包括可能 测量到的小区名单 (NeighCellList) 。 可选地, 基站在预先配置了多个 RRM 测量流程之后, 可以将其中的一个或几个设置为对于小区 NeighCellList之外 的小区, 即使发现了, 也不对其来进行测量; 或者, 即使测量 NeighCellList 之外的小区,也不将这些小区的测量结果进行上报。仍然以图 2a的例子为例, 第二 RRM测量流程 (虚线表示的子帧) 可以发现第一小小区、 第二小小区 和第三小小区, 按照本实施例的方法, 可以设置可能测量到的小区名单为第 一小小区和第二小小区, 即规定目标小区仅为第一小小区和第二小小区, 那 么在第二 RRM测量流程对应的测量中,即使 UE发现了第三小小区也不进行 测量; 或者可以规定对第三小小区的测量结果不进行上报。
本实施例,基站通过为载波配置至少两个互相独立的无线资源管理 RRM 测量流程, 每个所述 RRM测量流程的配置信息包括一组测量时域信息和对 应的测量参数信息,并向 UE发送所述至少两个互相独立的 RRM测量流程的 配置信息,以使所述 UE采用所述至少两个互相独立的无线资源管理 RRM测 量流程对每个载波进行 RRM测量, 通过采用至少两个所述互相独立的 RRM 测量流程对一个载波进行 RRM测量,再接收所述 UE上报的 RRM测量结果; 由于所述至少两个互相独立的 RRM测量流程可以针对不同的邻区来配置, 因此每个 RRM测量流程对应的测量时域信息与待测邻区发送 RRM测量参考 信号的时域信息相匹配, 因此能够测量到非持续发送 RRM测量参考信号的 邻区, 获得的准确的邻区发现和邻区测量结果。
图 8为本发明提供的邻区测量方法实施例三的交互流程图, 本实施例描 述 UE与基站互相交互完成邻区测量的方法,本实施例的 UE可以为图 1或图 4所示实施例的 UE, 本实施例的基站可以为图 3或图 5所示实施例的基站。 如图 8所示, 本实施例的方法可以包括:

其中每组测量时域信息与至少一个相邻基站发送发现参考信号的时域信 息相匹配。
具体实现时, 所述至少两组测量时域信息可以包括:
所述基站为每个载波配置的至少两个测量子帧集合, 所述每个测量子帧 集合为一组测量时域信息; 或者
所述基站在所述为每个载波配置的测量子帧集合中划分出的至少两个子 集, 所述每个子集为一组测量时域信息; 或者
所述基站为每个载波配置至少两个测量间隙 gap,所述每个测量 gap为一 组测量时域信息; 或者
所述基站在所述测量 gap中划分出的至少两个子 gap,所述每个子 gap为 一组测量时域信息。
具体的实现过程可以参见 UE实施例一中关于所述至少两组测量时域信 息的描述, 此处不再赘述。
进一歩地, 所述测量参数信息包括以下参数中的至少一个: 测量带宽、 可能测量到的小区名单、 小区黑名单、 事件触发上报的门限、 上报周期、 上 报测量量、 上报事件驱动量、 上报的最大小区数量、 层三滤波器参数设置、 CRS天线端口 1是否存在。
其中对于配置参数的详细说明可以参见 UE实施例一中关于配置参数的 描述。
歩骤 802、 基站向 UE发送所述至少两个互相独立的 RRM测量流程的配 置信息, 每个所述 RRM测量流程的配置信息包括一组测量时域信息和对应 的测量参数信息。
歩骤 803、 UE采用所述至少两个互相独立的无线资源管理 RRM测量流 程对每个载波进行 RRM测量。
歩骤 804、 UE将所述 RRM测量结果上报给所述基站。
具体实现时, 歩骤 804可以包括:
所述 UE分别将至少两个所述 RRM测量结果上报给所述基站; 或者 所述 UE在至少两个所述 RRM测量结果中选择一个所述 RRM测量结果 上报给所述基站; 或者
所述 UE将至少两个所述 RRM测量结果进行结合, 例如进行加权平均, 之后上报给所述基站。
可选地, 在一种可能的实现方式中, 所述测量参数信息包括可能测量到 的小区名单, 则歩骤 804可以为: 所述 UE仅上报的在所述测量得到的 RRM 测量结果中属于所述可能测量到的小区名单中的小区的 RRM测量结果。
本实施例, UE通过接收基站发送的至少两个互相独立的 RRM测量流程 的配置信息, 并通过采用至少两个所述互相独立的 RRM测量流程对一个载 波进行 RRM测量, 分别获得至少两个 RRM测量结果, 并将所述 RRM测量 结果上报给所述基站; 由于所述至少两个互相独立的 RRM测量流程可以针 对不同的邻区来配置, 因此每个 RRM测量流程对应的测量时域信息与待测 邻区发送 RRM测量参考信号的时域信息相匹配, 因此能够测量到非持续发 送 RRM测量参考信号的邻区, 获得的准确的邻区发现和邻区测量结果。
