Description

一种测量处理方法及装置 技术领域
本发明涉及通信技术领域, 具体是涉及一种测量处理方法及装置。
背景技术
通用移动通讯系统 ( Universal Mobile Telecommunications System , UMTS )是釆用宽带码分多址( Wideband CDMA , WCDMA ) 空中接口技术 的第三代移动通信系统。 随着第三代移动通信系统(3GPP ) 的发展, 为了能 在 UMTS 中釆用微波存取全球互通(WiMAX )等高速无线接入技术, 保持 3GPP 标准中 WCDMA/全球移动通信系统 ( Global System for Mobile Communications , GSM ) 的生命力和竟争力, 3GPP提出了 UMTS的长期演 进( Long Term Evoluation, LTE ), LTE的物理层以正交频分多址接入( OFDM ) 技术为基础。
在 LTE物理层技术中, 系统带宽可以是 1.25MHz、 1.6MHz、 2.5MHz、 5MHz、 10MHz、 15MHz和 20MHz, 系统资源为时频资源, 即包括时域和频 域两维的资源。 LTE系统中 1个子载波占用带宽为 15KHz。 LTE系统中一帧 为 10ms, 分为 20个时隙, 每个时隙有 7个 OFDM符号, 上下行都存在 LTE 导频。 比如, 如图 1 所示, 下行导频在时域上位于每个时隙的第一个和第五 个 OFDM符号。
在 UMTS的 WCDMA系统中, 为支持系统的移动性, 需要测量导频的信 号质量, 对于 LTE系统来说, 同样如此。
目前, WCDMA系统中网络侧和终端侧的测量模型如图 2所示。
在图 2所示的模型中,
A表示物理层内部测量所得的测量釆样数据。
层 1滤波( Layer 1 filtering )表示对输入的测量釆样数据 A进行物理层滤 波处理。
B表示物理层滤波处理后得到的测量量。 层 3滤波( Layer 3 filtering )表示对测量量 B进行高层滤波处理。
C表示高层滤波处理后得到的测量结果。
D表示测量报告。
测量 4艮告评估(Evaluation of reporting criteria), 对于网络侧来说, 表示 网络侧高层根据测量结果 C 判断是否需要执行相应的无线资源管理(Radio Resource Management, RRM)过程, 对于终端侧来说, 则表示判断终端侧是 否需要向网络侧高层发送测量报告 D。
基于上述模型, WCDMA 系统中针对终端侧测量釆样数据的处理方案具 体包括以下几个步骤:
步骤 a、 终端侧物理层执行测量, 获取测量釆样数据;
步骤 b、终端侧物理层对测量釆样数据进行物理层滤波处理后得到的测量 量提供给终端侧高层;
步骤 c、 终端侧高层按照公式(1 )所示的滤波方式对收到的测量量进行 处理后, 得到测量结果。
Fn =(l-a)-Fn_x+a-Mn ( 1 ) 其中, Fn表示当前滤波处理后的测量结果, Fn-1表示前一个滤波处理后 的测量结果, Mn表示当前收到的物理层传送来的测量量, n为自然数, F0为 物理层第一次传送来的测量量 Ml, a= \/2(m 其中的 k为滤波系数。
该处理具体是将当前的测量量与前一次处理后所得的测量结果进行滑动 滤波处理, 即将当前的测量量与前一次处理所得的测量结果分别乘以加权系 数后相加, 从而得到当前的测量结果。 其中的两个加权系数之和为 1。
步骤 d、终端侧高层依据滤波后得到的每个测量结果确定是否需要触发发 往网络侧高层的测量报告, 或者触发其他的无线资源管理(RRM)过程。
比如, 终端侧高层在确定得到的测量结果 F3已超出预定的测量值后, 则 可以确定需要向网络侧高层发送测量报告。
对于网络侧来说, 其处理过程与上述过程类似, 所不同的是, 网络侧高 层在执行上述步骤 d所对应的处理时, 具体是根据滤波后得到的每个测量结 果确定是否需要执行相应的 RRM过程。
通过上述处理, 就可以实现对信号的测量。 当然也包括了对导频信号质 量的测量。
然而, 发明人发现 WCDMA系统中的测量频段对于所有测量釆样数据来 说都是相同的, 上述测量处理主要是针对时域的多个不同测量釆样数据。 而 LTE系统中不同测量釆样数据所对应的测量频段的载波位置和带宽是不同的, 如果对 LTE系统釆用 WCDMA系统中已有的 Layer 3滤波处理, 则显然没有 考虑到 LTE信号测量釆样数据同时具有时域和频域的特性。
而如果 LTE系统不对测量量进行 Layer 3的滤波处理,则会导致系统需要 处理更多的测量釆样数据, 造成不必要的内存占用和测量时间长。 并且, 如 果没有一个统一且效果好的 Layer 3滤波处理方法, 各个厂商很可能会釆用各 不相同的滤波处理方法, 这必然会造成测量结果不一致, 从而影响网络性能。 发明内容

该测量具体可以是待测量装置的物理层执行测量。
本步骤中所获取的测量釆样数据 Mkn中的 k表示该测量釆样数据所在的子 载波, n则表示该测量釆样数据在时间轴上为第 n个数据。 该 k值通常只有有 限的几个, 而 n则为多个, 因此测量釆样数据 Mkn会出现多个数据对应相同的 子载波的情况。
步骤 302、 对测量釆样数据进行物理层滤波处理后得到测量量。
该测量具体可以是对待测量装置的物理层进行滤波处理, 并将得到的测 量量提供给待测量装置的高层。
步骤 303、 对所述的测量量执行时频的归一化滤波处理, 得到测量结果。 该处理具体可以是由待测量装置的高层执行。
步骤 304、 对得到的测量结果进行评估。 该评估处理具体可以是待测量装置的高层进行评估, 从而确定后续需要 执行的操作。 比如, 可以根据测量结果确定是否需要触发测量报告或切换之 类的 RRM过程。
通过上述处理, 即完成了对测量釆样数据的测量。
其中, 步骤 303 中所述的时频的归一化滤波处理, 具体可以使用如下几 种方法。 下面对这些方法进行详细描述。
比如, 该时频的归一化滤波处理可以是根据测量量所在的频域进行处理 , 即可以根据公式(2)对测量量根据不同频域进行归一化滤波处理。
^„ =(!-«)· Fn_ + α(^Μχ χ + k2M22 + ... + kk-M (2)
其中, Fn表示当前滤波处理后的测量结果, Fn-1表示前一个滤波处理后 的测量结果, n为自然数, F。为物理层第一次执行物理层滤波处理后传送来的 测量量, 即 Mu, 参数 kk表示测量釆样数据所在的子载波的系数, a的取值可 以根据系统的需要确定, 比如, 可以取 a = l/2(k 2), 其中的 k是滤波系数, 也可以取 a = 1/k, 当然还可以取其他值。
该处理具体是将在 k个子载波上的连续 n个测量量分别根据其所在的频 域进行归一化处理, 即将每个测量量与该测量量对应的子载波的系数相乘, 再将得到的结果与前一次处理后所得的测量结果进行滑动滤波处理, 即将得 到的结果与前一次处理后所得的测量结果分别乘以加权系数后相加, 从而得 到当前的测量结果。 其中的两个加权系数之和为 1。
该时频归一化滤波处理还可以是釆用公式(3)对测量量进行滤波处理。
Fn ={\-a)- Fn_x + αλΜη + α2Μ22 +.... + akMkn ( 3 )
其中, Fn表示当前滤波处理后的测量结果, Fn-1表示前一个滤波处理后 的测量结果, n为自然数, F。为物理层第一次传送来的测量量 Mu, k表示测量 釆样数据所在的子载波数, 则需要满足下述的公式(4), 且 k针对相同的 频域信息可以取相同的值, 也可以取不同的值。
α, +α2 + .... + ak =a (4)
该处理具体是将在 k个子载波上的连续 n个测量量与前一次处理后所得 的测量结果进行滑动滤波处理, 即将每个测量量与其所对应的子载波的加权 系数相乘, 将所得的 n个值与前一次处理后所得的测量结果与加权系数的乘 积相加, 从而得到当前的测量结果。 其中的 n + 1个加权系数之和为 1。
该时频的归一化滤波处理还可以是单独的频域归一化处理, 即使用公式 ( 5 )所示的处理方法。
Fn = {\ -a) - Fn_^ a - n -Mnn_ ( 5 )
其中, F。为物理层第一次传送来的测量量 Mu , km是不同载频对某一选定 的归一化载频的归一化参数, 该归一化载频可以直接选定为频段内或测量带 宽内的中心载频, 也可以根据子载波位置、 多径环境、 信号变化、 系统工作 模式等进行选择, 其他载频与所选择的归一化载频之间的比值或信号差异即 为归一化参数。 如前所述, a的取值可以根据系统的需要确定, 比如可以取 a = l/2 (k/2) , 其中的 k是滤波系数。
该处理具体是将当前子载波 km上的测量量根据其所在的频域对选定的归 一化载频进行归一化处理, 即将该测量量与对应子载波所选定的归一化载频 的归一化参数相乘, 之后将得到的结果与前一次处理后所得的测量结果进行 滑动滤波处理, 即将得到的结果与前一次处理后所得的测量结果分别乘以加 权系数后相加, 从而得到当前的测量结果。 其中的两个加权系数之和为 1。
另外, 上述处理所釆用的都是线性滤波处理。 本发明实施例还可以釆用 非线性的滤波处理方法, 则上述各个公式所对应的滑动滤波处理则可以改为 非线性的滤波处理。 对于上述各个公式来说, 则可以在上述各个公式中使用 非一阶的 和 Mkn
上述实施例提供了待测量装置在高层对测量釆样数据执行时频的归一化 滤波处理的具体步骤。 对于该处理之前的待测量装置物理层物理层滤波处理 来说, 其所处理的测量釆样数据也具有时频特性, 为使得本发明实施例具有 更好的测量处理效果, 本发明实施例还提供了待测量装置物理层对测量釆样 数据执行时频的物理层滤波处理的具体步骤。 下面对本发明实施例中待测量 装置物理层执行的时频物理层滤波处理的具体步骤进行详细描述。 待测量装置物理层执行的时频物理层滤波处理方式主要是对同时或同一 周期内不同子载波频率的测量釆样数据进行频域和时域的滤波处理, 其中, 该周期具体是测量周期, 通常与多径环境、 信号变化、 系统工作模式等相关。 该物理层滤波处理具体同样可以釆用上述公式( 2 )、 ( 3 )和( 5 )所对应的处 理方式, 所不同的是, 在物理层滤波处理中, 这几个公式中的 Mkn代表的是物 理层测量所得的测量釆样数据, 而不是物理层处理后的测量量, F。代表的是第 一个测量釆样数据的对应值。
该物理层滤波处理还可以选用 WCDMA中层 3的滤波处理方式, 即釆用公 式(1 )所示的处理方法, 该处理具体是将当前的测量釆样数据与前一次处理 后所得的测量量进行滑动滤波处理, 对于物理层滤波处理所得的第一个测量 量来说, 其所对应的前一次处理所得的测量量设定为第一个测量釆样数据的 对应值, 也就是说,公式( 1 )中的 F。代表的是第一个测量釆样数据的对应值。
另外, 还可以釆用类似的线性滤波处理, 但不考虑物理层前一处理所得 的测量量, 该处理所对应的公式(6 )具体如下。
= αχΜϊη + α2Μ + ... + α ( 6 )
其中, Fn表示当前滤波处理后的测量结果, n为自然数, 同样需要满 足上述的公式( 4 ), 且 <3 k针对相同的频域信息可以取相同的值, 也可以取不 同的值。
该处理具体是将在 k个子载波上的连续 n个测量釆样数据根据其所在的 频域进行归一化处理, 即将每个测量釆样数据与对应子载波的系数相乘后相 加, 从而得到当前的测量量。 其中, 所有的加权系数之和为<3。
与待测量装置的时频滤波处理类似, 待测量装置也可以釆用非线性的物 理层滤波处理, 即可以将上述各个公式所对应的滑动滤波处理改为非线性的 滤波处理。
另外, 待测量装置物理层还可以是对所有的测量釆样数据进行平均算法 处理, 即釆用公式(7 )进行滤波处理。
Fn = (Mln +M2n + ... +Mkn)/n ( 7 ) 该物理层滤波处理具体可以是对 n个测量釆样数据 Μπ, ... . , Mkn取均值。 本发明的上述实施例所提供的多种测量处理方案, 在对测量所得的测量 釆样数据进行物理层滤波处理后, 对所得的测量量进行时频的归一化滤波处 理, 从而得到最终的测量结果, 该归一化滤波处理同时考虑了测量釆样数据 的时域和频域特性, 使得得到的测量结果更准确, 从而优化了网络性能。 方案, 且包括了针对测量釆样数据的时频特性的处理方案, 进一步保证了测 量结果的准确性。
且本发明的上述实施例所提供的测量处理方案不只限于 LTE 系统中, 还 可以用于其他系统的类似测量处理上。
另外, 通过统一使用本发明上述实施例提供的处理方案, 还能够保证各 个厂商得到一致的测量结果, 从而保证了网络性能的稳定性。

另外, 对于物理层滤波单元来说, 除了可以釆用现有 WCDMA 系统中的物 理层滤波处理, 该处理具体如公式( 1 )所示, 还可以釆用上述公式( 2 )、 ( 3 ) 和(5 ) 所对应的处理方式, 还可以釆用公式(6 ) 所示的类似的线性滤波处 理, 但不考虑物理层前一处理所得的测量量, 以及釆用公式(7 )所示的直接 对所有的测量釆样数据进行平均算法处理。
具体来说, 物理层滤波单元可以对收到的测量釆样数据与前一次处理所 得的测量量进行滑动滤波处理, 即将当前收到的测量釆样数据与前一次处理 所得的测量量分别乘以加权系数后相加, 从而得到当前的测量量。 其中的两 个加权系数之和为 1。 该处理具体对应上述公式(1 )。
