- the terminal may also use the system bandwidth of the camped cell as the measurement bandwidth for the currently camped cell or the same.
- the measurement is performed at the frequency point, and the measurement is performed in the same manner as above, and can be flexible.
- the measurement process of the terminal the terminal must complete the measurement of each frequency point in a fixed time, generally can be set to 480ms or 240ms. Therefore, giving the terminal the flexibility of specific sampling, on the other hand, also gives the terminal the space for adjusting the sampling bandwidth of different frequency points to ensure that it can complete the measurement within the specified time. Specifying the same measurement time for all frequency points helps to control the total measurement time, obtain overall measurement results in a timely manner, and make mobility decisions in a timely manner.
- the time period in which the terminal completes the measurement is N*480 ms.
- the terminal must complete all measurements before the end of this time period, and generate a measurement report to report to the upper layer, and then start the next measurement cycle.

For example, if the measured RSRQ value exceeds a certain threshold, or when the RSRQ of the two cells exceeds the threshold, the triggering event is triggered. Give the upper level and carry specific measurement results in the measurement report.

- the minimum measurement bandwidth of the network configuration is 6 RB, and when the measurement bandwidth of the network configuration is 6 RB, the terminal can be above and below the 6 RB bandwidth.
- Several RBs are extended at both ends as an increased measurement bandwidth and measurements are performed. Because 6RB is a small bandwidth, if this measurement bandwidth is used, the measurement error may be too large due to insufficient sample, giving the terminal a certain degree of freedom. Increasing the measurement sample can obtain more accurate measurement under the premise of the terminal power. result.

参考信号测量方法及装置 技术领域 本发明涉及通信领域， 具体而言， 涉及一种参考信号测量方法及装置。 背景技术 蜂窝移动通信系统的移动性是建立在移动终端的测量基础上的， 即由终端对当前 小区和众多相邻小区的参考信号强度或者质量进行测量， 之后或者由网络侧， 或者由 终端本身对测量结果进行评估， 继而做出停留在原小区还是移动到新小区的决策并执 行。 具体地， 对于在业务状态下的终端， 由终端对当前小区和相邻小区的信号进行测 量， 然后将测量结果上报给基站， 基站根据一定的算法指示终端的移动； 对于非业务 状态下的终端， 其过程也类似， 区别仅在于移动的判决在终端本身进行， 而不需要终 端将测量结果上报给基站， 也不需要基站将移动决策下发给终端。 从另一个角度， 终端对上述各小区的测量又可以根据小区频点和所属系统的差异 分成不同的类型： 如果测量小区的频点和终端当前驻留小区相同， 那么测量被称为同 频测量； 如果不同， 则被称为异频测量， 如果测量小区与当前驻留小区属于不同的系 统， 则被称为异系统测量， 比如驻留小区属于长期演进 （Long term evolution, 简称为 LTE)小区， 而另一小区属于通用移动通信系统 (Universal Mobile Telecommunications System, 简称为 UMTS) 小区。 现有技术中， 对于 LTE终端的测量是这样实现的： 协议规定了两种测量带宽， 即 6个无线资源块 （Resource Block, 简称为 RB ) 和 50个 RB， 终端选择其中之一来实 现测量。 工程实现中， 终端往往以当前小区的频带中心为基准， 测量在这个中心上的 6RB、 或者是 50RB 的参考信号强度或者质量。 但是， 上述测量方法只在规定的两种 测量带宽下测量， 不够灵活， 测量结果不够精确。 发明内容 本发明实施例提供了一种参考信号测量方法及装置， 以至少解决相关技术中终端 仅可以在规定的两种测量带宽下测量小区的参考信号， 测量方法不够灵活、 测量结果 不够精确的问题。
本发明实施例提供了一种参考信号测量方法， 包括： 基站配置与终端的测量频点 对应的测量带宽； 基站向终端发送频点和测量带宽。 基站配置与终端的测量频点对应的测量带宽包括： 基站根据终端当前驻留的小区 配置同频点和 /或异频点； 基站根据同频点和 /或异频点配置与同频点和 /或异频点对应 的同频测量带宽和 /或异频测量带宽。 在基站配置与终端的测量频点对应的测量带宽之后， 上述方法还包括： 基站通过 主信息单元 MIB向终端发送终端当前驻留的小区的系统带宽， 其中， 当前驻留的小区 的系统带宽可以作为当前驻留的小区的测量带宽或者同频点的测量带宽。 基站向终端发送频点和测量带宽包括： 基站在同频系统消息块上发送同频测量带 宽， 在异频系统消息块上发送异频测量带宽。 在小区是非 LTE小区的情况下， 终端根据小区所属的系统确定小区的系统带宽。 本发明实施例提供了一种参考信号测量方法， 包括： 终端接收到来自基站的频点 和与频点对应的系统带宽； 终端根据频点和系统带宽计算测量带宽； 终端根据测量带 宽测量参考信号。 终端根据频点和系统带宽计算测量带宽包括： 确定系统带宽作为测量带宽。 终端根据测量带宽测量参考信号包括： 终端在整个测量带宽上对连续的无线资源 块进行采样； 终端根据采样的无线资源块测量参考信号。 终端根据测量带宽测量参考信号包括： 终端对每个频点在预先设定的测量时间内 测量参考信号。 在终端对每个频点在预先设定的测量时间内测量参考信号之后， 还包括： 终端根 据测量结果生成测量报告； 终端向高层上报测量报告， 并根据预先设定的测量时间进 行下一周期的测量， 其中， 所述周期是所述预先设定的测量时间乘以频点个数。 在小区是非 LTE小区的情况下， 终端根据小区所属的系统确定小区的系统带宽。 本发明实施例提供了一种参考信号测量装置， 应用于基站， 包括： 配置模块， 设 置为配置与终端的测量频点对应的测量带宽； 发送模块， 设置为向终端发送频点和测 量带宽。

工程实现中， 可将当前驻留小区的系统带宽放在主信息单元（Management Information Base, 简称为 MIB) 中广播下发给该小区的所有终端。 需要说明的是， 在小区是非 LTE小区的情况下， 终端根据小区所属的系统确定小 区的系统带宽。 对于 LTE小区， 终端可以利用图 1所示的方法中配置的测量带宽测量 参考信号； 对于非 LTE小区， 基站不需要发送相应的测量带宽或者系统带宽， 因为非 LTE系统的无线制式的带宽都是固定的， 比如 UMTS系统的带宽是 3.84MHz, TD系 统的带宽是 1.28MHz等， 因此终端可以根据其所属的系统来确定其系统带宽。 上述确 定方法简单、 可靠。 本发明实施例还提供了一种参考信号测量方法， 图 2是根据本发明实施例的另一 种参考信号测量方法的流程图， 如图 2所示， 包括如下的步骤 S202至步骤 S206。 步骤 S202, 终端接收到来自基站的频点和与频点对应的系统带宽。 步骤 S204, 终端根据频点和系统带宽计算测量带宽。 步骤 S206, 终端根据测量带宽测量参考信号。 相关技术中， 终端仅可以在协议规定的两种测量带宽下测量小区的参考信号， 以 决策是否迁移到新小区， 测量方法不够灵活， 测量结果不够精确。 本实施例中， 终端 根据频点及其对应的系统带宽计算测量带宽， 并根据计算出的测量带宽测量参考信号 的强度或者质量， 并不局限于协议规定的两种测量带宽， 保证了参考信号测量的准确 程度。 本发明还提供了一种优选实施方式， 即终端根据频点和系统带宽计算测量带宽包 括： 确定系统带宽作为测量带宽。 本优选实施方式中， 终端直接将基站下发的系统带 宽作为测量带宽进行参考信号的测量， 这样省去了计算测量带宽的步骤， 考虑到有时 只需要进行简单测量的情况， 本优选方式即可得到满足要求的测量结果。 终端在测量参考信号时， 还需对整个测量带宽进行采样， 所以， 终端根据测量带 宽测量参考信号包括： 终端在整个测量带宽上对连续的无线资源块进行采样； 终端根 据采样的无线资源块测量参考信号。 采样点覆盖到整个测量带宽， 从而保证了测量能 全面地反映出频段上的信号情况， 但终端无需对测量带宽上的每一个 RB都要进行采 样测量， 从而降低了终端采样测量的工作量， 节省了能量消耗。 终端对每个频点测量都必须在固定的时间内完成， 一般可以设置为 480ms 或者 240ms 0 所以， 终端根据测量带宽测量参考信号包括： 终端对每个频点在预先设定的
测量时间内测量参考信号。 本优选实施例中， 对所有频点规定相同的测量时间有助于 控制总的测量时间， 及时获得整体测量结果， 并及时做出移动性决策。 优选地，在终端对每个频点在预先设定的测量时间内测量参考信号之后，还包括: 终端根据测量结果生成测量报告； 终端向高层上报测量报告， 并根据预先设定的测量 时间进行下一周期的测量，其中，所述周期是所述预先设定的测量时间乘以频点个数。 以 480ms为例， 如果基站向终端下发的频点数为 N (包括同频频点和异频频点）， 那 么终端完成测量的时间周期是 N*480ms。 需要说明的是， 在小区是非 LTE小区的情况下， 终端根据小区所属的系统确定小 区的系统带宽。 对于 LTE小区， 终端可以利用图 1所示的方法中配置的测量带宽测量 参考信号； 对于非 LTE小区， 基站不需要发送相应的测量带宽或者系统带宽， 因为非 LTE系统的无线制式的带宽都是固定的， 比如 UMTS系统的带宽是 3.84MHz, TD系 统的带宽是 1.28MHz等， 因此终端可以根据其所属的系统来确定其系统带宽。 由上述实施例可知， 本发明终端的测量带宽可以灵活配置， 或者是对于某些小区 扩展测量带宽长度， 从而获得更为精确的测量结果， 为移动性决策提供更可信的依据; 当这种灵活配置是由网络侧所控制时， 基站可以根据不同的网络部署场景来配置最适 合的测量带宽， 使得终端的测量达到测量准确度和测量耗电之间的最佳平衡。 下面将结合实例对本发明实施例的实现过程进行详细描述。 以下优选实施例中终端的测量对象是小区的参考信号， 具体包括终端当前驻留小 区和系统消息中所配置的相邻小区的参考信号； 具体地， 测量的是参考信号强度 (Reference Signal Received Power,简称为 RSRP)或者参考信号质量（Reference Signal Received Quality, 简称为 RSRQ)， 本发明的方法对于测量 RSRP和 RSRQ都是同样适 用的， 但为了描述方便， 在下面的优选实施例中以测量 RSRQ为例。 优选实施例一 图 3是根据本发明优选实施例一的参考信号测量方法的流程图， 如图 3所示， 在 网络配置测量带宽的条件下， 终端按照配置的测量带宽进行 RSRQ测量， 具体包括如 下的步骤 S302至步骤 S304。 步骤 S302， 基站根据具体的网络部署配置测量带宽， 并下发到终端。 具体地， 基站首先需要配置终端的测量频点， 包括同频的频点和异频的频点， 相 应地， 基站配置的测量带宽也包括同频测量带宽和异频测量带宽。 所谓的同频和异频
是以基站所在小区的频点为参考， 相同的为同频， 不同的为异频。 由于网络的运营商 非常了解每个小区的具体部署情况， 因此由网络侧配置终端的测量带宽可以利用到网 络已知的信息， 对每个具体的小区设置最优的测量带宽值， 并且不同小区的配置可以 灵活变换， 在保证测量准确程度的同时又减少了终端不必要的测量， 达到准确度和测 量耗电的平衡。 下面结合两个例子描述具体网络部署下的测量带宽配置。 图 4是根据本发明优选实施例一的具体网络部署的带宽示意图，如图 4所示， celll 的系统带宽为 BW1， cell2的系统带宽为 BW2， cell3的系统带宽为 BW3。基站配置时， 对于 celll和 cell3配置它们的测量带宽即是它们的系统带宽，对于 cell2虽然它的系统 带宽为 BW2， 但是它与 celll的频带重叠部分是 BW2'， 为了真实反映出终端在 cell2 驻留时受到的有用信号和干扰的情况， 只需要测量 BW2'上的 RSRQ即可， 因此基站 配置 cell2的测量带宽为 BW2'。 在具体配置时， 基站是根据终端当前所驻留的小区来进行同频点和异频点的配置 的。 比如终端当前驻留在 celll , 那么基站就配置同频频点 F1 和同频点的测量带宽 BW1 , 以及异频点 F2、 F3和对应异频点的测量带宽 BW2'和 BW3 (这里 Fl、 F2、 F3 分别是 celll、 cell2、 cell3的中心频点）。 图 5是根据本发明优选实施例一的另一种具体网络部署的带宽示意图， 图 5所示 与图 4的区别在于在 cell3的频带上还叠加了 cell4的频带，显然，最佳地，基站对 cell4 的测量带宽设置为 BW4，但由于 cell4的频点和 cell3的频点都是 F3，并且测量带宽是 依附于频点的， 所以基站对于异频点 F3配置的测量带宽仍然为 BW3。 基站配置测量带宽完成后就将测量带宽信息连同频点下发给终端。 具体来说， 同频点的测量带宽在同频系统消息块 （System Information Block, 简 称为 SIB3 ) 上发送； 异频点的测量带宽在异频系统消息块 （SIB5 ) 上发送。 更优情况下， 基站在下发频点和测量带宽的同时， 还将终端当前驻留小区的系统 带宽一同下发。仍然以上面的图 5为例， 如果终端此时驻留在 cell4中， 那么基站可将 cell4的系统带宽 BW4—同下发给终端。 工程实现中， 可将驻留小区的系统带宽放在主信息单元 （MIB) 中广播下发给该 小区的所有终端。 步骤 S304, 终端收到网络下发的频点和测量带宽后， 据此进行 RSRQ测量。
具体地， 终端的测量也是依据频点和对应的测量带宽来进行的。 这里需要说明， LTE系统的带宽是以 RB个数为度量的， 一个 RB是 LTE系统中最小的带宽单位， 也 是本发明中终端实施具体测量的一个采样点， 一个具体的采样测量是指终端测量某个 RB上的 RSRQ值。 终端的测量必须覆盖到频点 （同频点或异频点） 所对应的所有测量带宽， 但具体 的采样方式可以是灵活的。 如图 6所示是一种终端测量的具体采样方式， 终端对若干 组连续的 RB采样测量， 组与组之间间隔一定数量的空余 RB。如图 7所示是另一种具 体的采样方式， 测量带宽被等分成若干个更小的测量单元， 终端在每个测量单元上随 机的选取若干个 RB采样测量， 采样可以非连续的， 如第一个采样单元； 也可以是连 续的， 如第二个采样单元。 总之， 终端有多种具体的实现形式来进行采样， 采样点覆盖到整个测量带宽， 从 而保证了测量能全面地反映出所述频段上的信号情况， 但这并不意味着终端必须对测 量带宽上的每一个 RB都要进行采样测量， 从而降低了终端采样测量的工作量， 节省 了能量消耗。 对于步骤 S302中所述的优先情况，如果基站还将终端当前驻留小区的系统带宽下 发给了终端， 那么终端也可以以驻留小区的系统带宽作为测量带宽对当前驻留小区或 者是同频点来执行测量， 测量的具体方式与上面相同， 可以是灵活的。 从另一个角度来看终端的测量过程， 终端对每个频点测量都必须在固定的时间内 完成， 一般可以设置为 480ms或者 240ms。 所以， 给予终端具体采样的灵活性， 从另 一方面也给予了终端对于不同频点的测量带宽调整不同采样策略的空间， 以确保其都 能在规定的时间内完成测量。 对所有频点规定相同的测量时间有助于控制总的测量时间， 及时获得整体测量结 果， 并及时作出移动性决策。 以上面的 480ms为例， 如果基站向终端下发的频点数为 N (包括同频频点和异频频点）， 那么终端完成测量的时间周期是 N*480ms。 终端必须在这个时间周期结束之前将所有的测量完成， 并生成测量报告上报给高 层， 然后开始下一个测量周期。 具体来说， 终端向高层上报测量报告是以触发事件的形式来执行， 比如测量的 RSRQ值超过某个门限， 或者是两个小区的 RSRQ超过了门限等调节满足时， 触发某 个触发事件上报给高层， 并在测量报告中携带具体的测量结果。 之后高层根据事件组 合和具体 RSRQ值来决定移动性策略或者是上报给基站。 这些与现有技术并无不同。
优选实施例二 图 8是根据本发明优选实施例二的参考信号测量方法的流程图， 如图 8所示， 包 括如下的步骤 S802在步骤 S804。 步骤 S802， 网络配置系统带宽， 并下发给终端。 步骤 S804, 终端根据配置的系统带宽进行测量。 与上述优选实施例一不同的是基站并没有配置每个频点的测量带宽， 而是将每个 频点的系统带宽下发至终端。 参考图 4的网络场景， 网络侧下发的是频点 Fl， F2, F3 和其对应的带宽 BW1， BW2, BW3。 终端在收到网络下发的频点和系统带宽信息后有两种选择： ( 1 ) 终端简单地以系统带宽作为测量带宽来进行测量； 或者
(2)终端根据频点和各频点的系统带宽自己计算出测量带宽， 并以这个计算出的 测量带宽进行测量。 仍以图 4为例， Fl、 BW1和 F2、 BW2对于终端是已知的， 因此终端可以计算出 celll和 cell2的重叠频带 BW2'， 以此作为 F2的测量带宽。而对于图 5中的部署场景， 终端在已知 F3、 BW3、 BW4的情况下， 可以计算出 celll和 cell3的重叠频带部分， 也可以计算出 celll、 cell3、 cell4 共同重叠部分， 而终端可以根据自身的需要来设定 F3的测量带宽， BW3或者是 BW4。 上述方式的好处是进一步地给予终端灵活度结合 自身情况而设定测量带宽。 终端在确定了测量带宽后，执行的具体抽样、测量过程和优选实施例一是相同的， 此处不再赘述。 优选实施例三 图 9是根据本发明优选实施例三的异构网络部署的示意图， 如图 9所示， celll是 LTE小区并且是终端当前驻留小区，频点为 F1，带宽为 BW1， cell3是 UMTS小区（也 可以是 GSM小区， TD-SCDMA小区等， 只需是非 LTE小区）， 频点为 F3， 带宽为 BW3。 在这种网络部署下，对于 celll仍然可以用上述优选实施例一或优选实施例二中的 方式来进行测量， 但对于 cell3， 基站不需要发送相应的测量带宽或者是系统带宽， 因
为非 LTE系统的无线制式的带宽都是固定的， 比如对于 UMTS是 3.84MHz, TD是 1.28MHz等， 因此终端可以根据其所属的系统来确定其系统带宽。 优选实施例四 本优选实施例可以看作是优选实施例一的更进一步优化， 网络配置的测量带宽最 小值是 6RB， 并且当网络配置的测量带宽是 6RB时， 终端可以在这 6RB带宽的上下 两端各扩展若干个 RB， 作为增加的测量带宽， 并实施测量。 因为 6RB是一个很小的带宽，如果以此作为测量带宽可能会由于样本不够而造成 测量的误差过大， 给予终端一定的自由度增加测量样本可以在终端电量允许的前提下 获得更加准确的测量结果。 需要说明的是， 在附图的流程图示出的步骤可以在诸如一组计算机可执行指令的 计算机系统中执行， 并且， 虽然在流程图中示出了逻辑顺序， 但是在某些情况下， 可 以以不同于此处的顺序执行所示出或描述的步骤。 本发明实施例提供了一种参考信号测量装置， 应用于基站， 该参考信号测量装置 可以用于实现上述图 1所示的参考信号测量方法。图 10是根据本发明实施例的参考信 号测量装置的结构框图， 如图 10所示， 包括配置模块 1002和第一发送模块 1004。 下 面对其结构进行详细描述。 配置模块 1002， 设置为配置与终端的测量频点对应的测量带宽； 第一发送模块 1004， 连接至配置模块 1002， 设置为向终端发送频点和配置模块 1002配置的与频点 对应的测量带宽。 图 11是根据本发明优选实施例的参考信号测量装置的具体结构框图一， 如图 11 所示， 上述配置模块 1002包括： 第一配置子模块 10022， 设置为根据终端当前驻留的 小区配置同频点和 /或异频点； 第二配置子模块 10024， 连接至第一配置子模块 10022， 设置为根据第一配置子模块 10022 配置的同频点和 /或异频点配置与同频点和 /或异频 点对应的同频测量带宽和 /或异频测量带宽。 图 12是根据本发明优选实施例的参考信号测量装置的具体结构框图二， 如图 12 所示， 上述装置还包括： 第二发送模块 1006， 连接至配置模块 1002， 设置为通过 MIB 向终端发送终端当前驻留的小区的系统带宽， 其中， 当前驻留的小区的系统带宽可以 作为当前驻留的小区的测量带宽或者同频点的测量带宽。
