Description

一种测量参数的指示方法及装置
技术领域
本发明涉及通信领域， 具体涉及一种测量参数的指示方法及装置。
背景技术
随着移动通信技术的蓬勃发展， 无线通信***呈现出移动化、 宽带化和
IP ( Internet Protocol , 互联网协议）化的趋势。 LTE ( Long Term Evolution , 长期演进）项目是 3G ( 3rd Generation, 第三代） 的演进， LTE釆用 OFDM ( Orthogonal Frequency Division Multiplexing , 正交频分复用 ) 和 MIMO ( Multiple-Input Multiple-Out-put , 多输入多输出）作为其无线网络演进的唯 一标准， 主要目的是为了改善小区边缘用户的性能， 提高小区容量和降低系 统延迟。
LTE-A ( LTE-Advanced, 演进 LTE )进一步扩充了 LTE的性能， 其关键 技术有载波聚合、 中继和异构网等。 切换作为无线资源管理中的一项重要功 能， 切换的成功与否很大程度上跟移动台测量的准确度相关。 如果移动台不 能较准确地进行测量， 反映信道状况给基站， 则就不能成功地进行切换， 从 而导致过早或过晚切换， 这对于时延有较高要求的业务很不利， 例如对于语 音业务， 很可能会出现掉话， 严重影响用户通话质量。
在 E-UTRA ( Evolved Universal Terrestrial Radio Access, 演进的通用陆面 无线接入）中， 为了能够灵活部署网络， 支持多种***带宽， 如， 1.4、 3、 5、 10、 15和 20MHz。 将 PSS(Primary Synchronization Signal, 主同步信号) /SSS ( Secondary Synchronization Signal, 副同步信号)和物理广播信道 ( Physical Broadcast Channel, PBCH )分配在中央 6个 RB ( Resource Block, 资源块） 上用于小区搜索， 这样能够独立于不同的信道带宽。 除此之外， 窄带测量带 宽还有助于减少能量的开销， 降低 UE ( User Equipment, 用户设备）处理的 复杂度等。但是，在 HetNet ( Heterogeneous Network,异构网络）或 CA(Carrier Aggregation, 载波聚合)的场景中，很可能会存在部分共信道的部署， 也就是， 宏小区 （Macro ) 、 微小区 （Pico )和微微小区 （Femto )使用不同的信道带 宽， 即服务小区和邻小区使用不同的带宽， 例如， 服务小区为 10MHz 的 E-UTRAN ( Evolved Universal Terrestrial Radio Access Network, 演进的通用陆 面无线接入网络） ， 邻小区为 5MHz的 E-UTRAN。 场景见图 1。 在这种情况 下， 服务小区内的终端如果仍然固定在中央 6个 RB上测量， 则将导致测量 不准确。 例如， 在图 1所示的场景中， 如果两窄带***间有 0.5MHz的保护 带宽， 则当移动台处在 10MHz***内使用中间 6个 RB进行 RRM ( Radio Resource Management , 无线资源管理）测量的时候， 两窄带***落入测量范 围内的带宽只有 2* ( 6*0.18/2-0.5/2 ) = 0.58MHz (约 3.2RB ) , 然后根据该测 量范围的测量结果估计当前小区的信道状况， 从而造成测量不准确。

本发明的较佳实施方式
下文中将参考附图并结合实施例来详细说明本发明技术方案。 需要说明 的是， 在不冲突的情况下， 本申请中的实施例及实施例中的特征可以相互组 合。
本发明实施例提供了一种由网络侧控制移动台进行 RRM测量带宽选择 的方法， 特别地， 可以用于在 E-UTRAN***中， 解决了在不同小区使用不 同带宽场景下， 服务小区的移动台的窄带测量存在不准确的问题。
在本发明实施例中， 提供了一种改进的基站， 该基站通过获得所述服务 小区的邻小区频带使用情况， 确定实际的使用场景， 进而确定接入该基站的 移动台的测量参数。
在本发明实施例中， 可以在基站中设置一种测量参数的指示装置， 由该 指示装置来确定移动中的测量参数， 并将该测量参数提供给移动台。
图 2是根据本发明实施例的测量参数的指示装置的结构示意图， 如图 2 所示， 该装置包括： 获取模块 20, 其设置成： 获取服务小区的邻小区的频带 使用信息， 其中， 所述频带使用信息包括： 邻小区的载频和邻小区的***带 宽； 确定模块 22, 其设置成： 与获取模块 20耦合， 并根据所述基站使用的 频带， 以及获得的所述各个邻小区的频带使用信息， 确定接入所述基站的移 动台的测量参数， 其中， 所述测量参数包括： 测量频点以及各个测量频点上 的测量带宽； 以及指示模块 24, 其设置成： 与确定模块 22耦合， 并向接入 所述基站的移动台指示所述测量参数。
通过本发明实施例提供的上述装置， 可以根据服务小区的邻小区的频带 使用信息， 确定移动台的测量参数， 而不是将测量频点固定在服务小区的频 率中心，避免了只在中心 6RB上测量时在某些场景下所测带宽内干扰不充分， 容易乐观估计信道状况的问题， 以及避免了只在中心 6RB上进行测量时可能 存在测量失准的问题， 从而提高了测量的准确度。
在本发明实施例中， 对于属于同一基站的不同小区， 基站内部直接能够 获得各个小区的带宽和频点信息， 对于属于不同基站的不同小区， 可以通过 基站之间的接口或者与上层通信获取邻小区的带宽和频点信息。 例如， 如图 3所示的 E-UTRAN***， E-UTRAN的演进型基站（ eNodeB )之间可由 X2 接口直接进行通信， 或者 eNodeB可以由 S1接口与上层进行通信， 获得邻小 区***所使用带宽和频点的情况。 因此， 在一个优选实施例中， 如图 4所示， 获取模块 20可以包括： 第一获取单元 200, 其设置成： 对于属于所述基站的 邻小区， 获取本地存储的该邻小区的频带使用信息； 以及第二获取单元 202, 其设置成： 对于不属于所述基站的邻小区， 通过与该邻小区的基站之间接口， 从该邻小区的基站获取该邻小区的频带使用信息， 或者通过接口与上层进行 通信， 获取该邻小区的频带使用信息。
在本发明实施例的一个优选实施方式中，确定模块 22可以通过以下方式 确定接入所述基站的移动台的测量频点的数量 N以及各个测量频点上的测量 带宽
N = (Bserv -Wgap) /Bneigh
BWn = B I N . 其中， 是第 n个测量频点的测量带宽， 服 ι =鮮 2 = .= B 总测量带宽， ^ 是服务小区的带宽， A 是邻小区的带宽， 是邻小区之 间的保护带宽的总和； 其中， 通过四舍五入计算 N值， N为正整数。 当 N > 1 时， 各个所述测量频点在带宽上间隔分布。
TS36.101里规定了 LTE***带宽使用率为 90%, 则 10M只用 9M、 5M 只用 4.5M、 3M只用 2.7M、 1.4M只用 1.26M。 剩下的 10%的带宽作为对其 它相邻***的保护带宽。
在本发明实施例中的 4叚设下， 不同场景的邻小区中心频率间隔不同， 5M 邻小区中心频率间隔为 5M, 3M邻小区中心频率间隔为 3M, 1.4M邻小区中 心频率间隔为 1.4M。
邻小区***之间的间隔带宽数量等于邻小区中心频率间隔减去邻小区系 统的实际使用带宽， 如， 5M邻小区之间的间隔带宽为 5-4.5=0.5M, 3M邻小 区之间的间隔带宽为 3-2.7=0.3M , 1.4M 邻小区之间的间隔带宽为 1.4-1.26=0.14M。
例如， 服务小区带宽为 10MHz, 邻小区带宽为 5MHz, 保护带宽总和为 0.5MHz, 测量总带宽为 6RB , 通过上述公式得 N = 2 , P "为 3RB。
例如， 服务小区带宽为 10MHz, 邻小区带宽为 3MHz, 保护带宽总和为
0.3+0.3=0.6MHz, 测量总带宽为 6RB , 通过上述公式得 N = 3 , "为 2KB。
例如， 服务小区带宽为 10MHz, 邻小区带宽为 1.4MHz, 保护带宽总和 为 0.14+0.14+0.14+0.14+0.14=0.7MHz, 测量总带宽为 6RB , 通过上述公式得 N = 6 , "为 1RB。
通过该优选实施方式， 将测量的频段尽量分散到整个***带宽内， 充分 反映整个***带宽内的干扰情况， 避免了原先只在中心 6RB上测量时在某些 场景下所测带宽内干扰不充分， 容易乐观估计信道状况的问题， 并且， 测量 带宽在***带宽内是均匀排布的，尽可能的反映较准确的***当前信道情况， 解决原先只在中心 6RB上进行测量时可能存在测量失准的问题。
在本发明实施例中，指示模块 24可以通过向所述移动台发送消息指示所 述测量参数， 其中， 所述消息中携带指示所述测量频点的参数和指示所述测 量带宽的参数。 例如， 所述消息可以通过***信息块（SIB )发送， 也可以通 过控制信令的方式进行发送。
在本发明实施例的一个优选实施方式， 指示所述测量频点的参数可以是 服务小区的中心频率以及各个所述测量频点相对于所述中心频率的偏置， 或 者， 也可以是各个所述测量频点的取值。 例如， 可以通过 EARFCN ( E-UTRA Absolute Radio Frequency Channel Number, E-UTRA绝对无线频率信道号）的 方式发送各个测量频点的取值。
在本发明实施例的一个优选实施方式中， 指示所述测量带宽的参数可以 是总测量带宽， 也可以是单个测量频点的测量带宽。 如果指示测量带宽的参 数为总测量带宽， 由于各个测量频点的测量带宽是相同的， 因此， 移动台可 以结合指示模块 24 所指示的测量频点的总数， 得到单个测量频点的测量带 宽。 需要说明的是， 虽然上述实施例中以测量参数的指示装置位于基站为例 进行说明， 但并不限于此， 在实际应用中， 该装置也可以位于基站之外， 通 过与基站进通信实现其各个模块的功能， 具体本发明实施例不再赘述。
根据本发明实施例， 还提供了一种测量参数的指示方法， 该方法可以通 过本发明实施例上述提供的测量参数的指示装置实现。
图 5是根据本发明实施例的测量参数的指示方法的流程图，如图 5所示， 该方法主要包括以下步骤（步骤 S502-步骤 S506 ) 。
步骤 S502, 服务小区基站获取所述服务小区的邻小区的频带使用信息。 步骤 S504, 服务小区基站根据自身使用的频带， 以及获得的各个邻小区 的频带使用信息， 确定接入服务小区基站的移动台的测量参数， 其中， 测量 参数包括： 测量频点以及各个测量频点上的测量带宽。
步骤 S506, 服务小区基站向接入服务小区基站的移动台指示所述测量参 数。
通过本发明实施例提供的上述方法， 可以根据服务小区的邻小区的频带 使用信息， 确定移动台的测量参数， 而不是将测量频点固定在服务小区的频 率中心，避免了只在中心 6RB上测量时在某些场景下所测带宽内干扰不充分， 容易乐观估计信道状况的问题， 以及避免了只在中心 6RB上进行测量时可能 存在测量失准的问题， 从而提高了测量的准确度。
在本发明实施例中， 对于属于同一基站的不同小区， 基站内部直接能够 获得个小区的带宽和频点信息， 对于属于不同基站的不同小区， 可以通过基 站之间的接口或者与上层通信获取邻小区的带宽和频点信息。 例如， 如图 3 所示的 E-UTRAN***， E-UTRAN的演进型基站（ eNodeB )之间可由 X2接 口直接进行通信， 或者 eNodeB可以由 S1接口与上层进行通信， 获得邻小区 ***所使用带宽和频点的情况。 因此， 在本发明实施例的一个优选实施方式 中， 服务小区基站获取所述服务小区的邻小区的频带使用信息的步骤包括： 对于属于所述服务小区基站的邻小区， 所述服务小区基站获取本地存储的该 邻小区的频带使用信息； 对于不属于所述服务小区基站的邻小区， 所述服务 小区基站通过与该邻小区的基站之间接口， 从该邻小区的基站获取该邻小区 的频带使用信息， 或者所述服务小区基站通过接口与上层进行通信， 获取该 邻小区的频带使用信息。
在本发明实施例的一个优选实施方式中， 服务小区基站根据自身使用的 频带， 以及获得的所述各个邻小区的频带使用信息， 确定接入所述服务小区 基站的移动台的测量参数的步骤包括： 服务小区基站按照以下公式确定接入 所述服务小区基站的移动台的测量频点的数量 N以及各个测量频点上的测量 带宽
N = (Bserv -Wgap) /Bneigh
BWn = B I N . 其中， 是第 n个测量频点的测量带宽， 服 ι =鮮 2 = .= B 总测量带宽， ^ 是服务小区的带宽， A 是邻小区的带宽， 是邻小区之 间的保护带宽的总和； 其中， 通过四舍五入计算 N值， N为正整数。 当 N > 1 时， 各个所述测量频点在带宽上间隔分布。
例如， 服务小区带宽为 10MHz, 邻小区带宽为 5MHz, 保护带宽总和为 0.5MHz, 测量总带宽为 6RB, 通过上述公式得 N = 2, P "为 3RB。
通过该优选实施方式， 将测量的频段尽量分散到整个***带宽内， 充分 反映整个***带宽内的干扰情况， 避免了原先只在中心 6RB上测量时在某些 场景下所测带宽内干扰不充分， 容易乐观估计信道状况的问题， 并且， 测量 带宽在***带宽内是均匀排布的，尽可能的反映较准确的***当前信道情况， 解决原先只在中心 6RB上进行测量时可能存在测量失准的问题。
在本发明实施例中， 所述服务小区基站可以通过向所述移动台发送消息 指示所述测量参数， 其中， 所述消息中携带指示所述测量频点的参数和指示 所述测量带宽的参数。 例如， 所述消息可以通过 SIB发送， 也可以通过控制 信令的方式进行发送。

在本发明实施例的一个优选实施方式， 各个测量频点可以为各个所述邻 小区的中心频点， 从而可以提高测量的准确性。 在本发明实施例中， 在所述服务小区基站向接入所述服务小区基站的移 动台指示所述测量参数的步骤之后， 所述方法还包括： 所述移动台按照所述 服务小区基站指示的所述测量参数进行测量。
与上述基站对应， 本发明实施例还提供了一种改进的移动台， 该移动台 根据服务小区基站所指示的测量参数进行小区测量。

在一个实施例中， 测量模块 62可以是设置成按照以下方式执行测量： 在 每次执行测量时都在各个所述测量频点的所述测量带宽上进行测量。
通过本发明实施例提供的小区测量装置， 可以根据服务小区基站指示测 量参数进行测量， 而不是将测量频点固定在服务小区的频率中心， 避免了只 在中心 6RB上测量时在某些场景下所测带宽内干扰不充分， 容易乐观估计信 道状况的问题， 以及避免了只在中心 6RB上进行测量时可能存在测量失准的 问题， 从而提高了测量的准确度。
在本发明实施例中， 服务小区基站所指示的测量参数是服务小区基站根 据所述服务小区的邻小区的频带使用信息所确定的， 具体参见本发明实施例 上述提供的测量参数的指示装置及方法中的描述， 在此不再赘述。 根据本发明实施例， 还提供了一种小区测量方法， 该方法可以通过本发 明实施例上述提供的小区测量装置实现。
图 7是根据本发明实施例的小区测量方法的流程图， 如图 7所示， 该方 法主要包括以下步骤 (步骤 S702-步骤 S704 ) 。
步骤 S702,移动台接收其接入的服务小区基站所指示的测量参数，其中， 所述测量参数包括： 测量频点以及各个测量频点上的测量带宽。
步骤 S704, 移动台按照所述测量参数进行小区测量。
通过本发明实施例提供的小区测量方法， 可以根据服务小区基站指示测 量参数进行测量， 而不是将测量频点固定在服务小区的频率中心， 避免了只 在中心 6RB上测量时在某些场景下所测带宽内干扰不充分， 容易乐观估计信 道状况的问题， 以及避免了只在中心 6RB上进行测量时可能存在测量失准的 问题， 从而提高了测量的准确度。
在本发明实施例中， 服务小区基站所指示的测量参数是服务小区基站根 据所述服务小区的邻小区的频带使用信息所确定的， 可参见本发明实施例上 述提供的测量参数的指示装置及方法中的描述， 在此不再赘述。
在本发明实施例中， 移动台接收其接入的服务小区基站所指示的测量参 数的步骤包括： 所述移动台接收所述服务小区基站发送的消息， 其中， 所述 消息中携带指示所述测量频点的参数和指示所述测量带宽的参数。 例如， 所 述移动台可以接收服务小区基站发送的 SIB或控制信令。
在本发明实施例的一个实施方式中，所述指示所述测量频点的参数包括： 所述服务小区的中心频率以及各个所述测量频点相对于所述中心频率的偏 置， 或者， 各个所述测量频点的取值。
在本发明实施例的一个优选实施方式， 指示所述测量频点的参数可以是 服务小区的中心频率以及各个所述测量频点相对于所述中心频率的偏置， 或 者， 也可以是各个所述测量频点的取值。 例如， 可以是服务小区基站以 EARFCN的方式发送各个测量频点的取值。
在本发明实施例的一个优选实施方式中， 各个测量频点上的测量带宽相 等， 则指示所述测量带宽的参数可以是总测量带宽， 也可以是单个测量频点 的测量带宽。 如果指示测量带宽的参数为总测量带宽， 由于各个测量频点的 测量带宽是相同的， 因此， 移动台可以结合服务小区基站所指示的测量频点 的总数， 得到单个测量频点的测量带宽。
在本发明实施例的一个优选实施方式， 各个测量频点为各个邻小区的中 心频点， 从而可以提高测量的准确性。
下面以 E-UTRAN***为例，对本发明实施例提供的技术方案进行说明。 在本发明实施例中， 服务小区基站通过网络（如图 3所示， 可由 X2接 口直接与邻小区基站进行通信， 或者由 S1接口与上层进行通信）获得所述服 务小区的邻小区频带使用情况， 然后根据实际的使用场景， 服务小区基站指 示其接入的移动台进行合适的测量， 服务小区中的移动台根据基站指示的测 量方式进行测量。
在本发明实施例中， 测量的总带宽、 测量的频点和测量的方式都是由网 络侧控制的， 并被下发给移动台执行， 完成测量动作。 在本发明实施例中， 测量的总 RB个数是一定值， 比如， 6RB、 15RB、 25RB, 可以由网络侧发送 给 UE的 IE ( Information Element, 信息元素） ( AllowedMeasBandwidth, 允 许的最大测量带宽）控制。
在本发明实施例中的测量方式是一种间隔釆样的方式。 即一次测量釆样 点 （即测量频点）在带宽上是间隔的， 可以由基站将服务小区的中心频率和 中心频率处的偏置发送给移动台， 或者可以由基站把邻区的频点通过 EARFCN发送给 UE。 移动台根据中心频率和偏置或者 EARFCN能够定位测 量频点。 在本发明实施例中， 测量频点的数目和每个测量频点的测量带宽则 可根据如下算法得到，
BWn = B I N
N = (Bserv -Wgap) IBneigh . 其中， "是第 n ( n=l,2,...,N )个测量频点的测量带宽， 由于是均分， 因此， 在本发明实施例中， BW1 = BW2 = ... = BWN ; ^^是总测量带宽， 如上所 述， 可以是 6RB、 15RB、 25RB; 为测量频点的总数； 是服务小区的带 宽， 如， 10MHz; A 是邻小区的带宽， 如， 5ΜΗζ; 。是邻小区之间的保 护带宽的总和， 如， 0.5MHz。
下面以测量总带宽为 6RB为例进行说明。
在本实施例中， 移动台不仅在***带宽中心 6RB上进行测量， 而^^站 通过上述算法计算后， 移动台根据基站的指示将 6RB分成两份 (3+3)RB (在 两个 5M带宽***载频中央的 3RB ) 、 三份（2+2+2 ) RB (在三个 3M带宽 ***载频中央的 2RB )或六份 ( 1+1+1+1+1+1 ) RB (在六个 1.4M带宽*** 载频中央的 1RB ) ， 总结如表 1所示， 进行多频点的窄带测量。 具体的频谱 部署场景如图 10A-10D所示， 分别对应表 1中的四种场景。
Figure imgf000016_0001
在实施中， 移动台进行 RRM测量时， 主要测量量有参考信号接收功率 ( Reference Signal Receiving Power, RSRP )和参考信号接收质量 ( Reference Signal Receiving Quality, RSRQ ) 。 对于 RSRP的测量， 由于它只包含 CRS ( Cell-specific (or Common) Reference Signal, 小区特定 (或通用 )参考信号 ) 中的信号强度测量， 因此， 它的测量跟具体小区使用的频带情况无关， 不需 要进行多频点的窄带测量。 然而， 由于 RSRP不能反映当前信道上干扰的情 况，因此,在实际应用中，需要对 RSRQ进行测量，其中， RSRQ = N * RSRP 1 RSSI , 其中 N是测量的 RB数， RSSI是 E-UTRAN载波接收信号强度指示， 即由终 端从所有源上观察到的总接收宽带功率， 包括公共信道的服务小区和非服务 小区、 邻信道干扰、 热噪声等。 为了上报准确的测量值， 移动台需要根据服 务基站所指示的测量方式进行测量。
下面结合附图来详细描述本实施例， 图 8是根据本发明实施例的由网络 侧控制移动台测量带宽的方法流程图，包括如下步骤（步骤 S802-步骤 S806 )。 步骤 S802, 服务小区基站通过网络与邻小区进行通信， 获得所述服务小 区的邻小区频带使用情况。
在实际应用中， 对于属于同一基站的不同小区， 基站内部直接能够获得 个小区的带宽和频点信息，对于属于不同基站的不同小区， E-UTRAN的演进 型基站 eNodeB之间可由 X2接口直接进行通信， 或者由 S1接口与上层进行 通信， 这样服务小区基站就能通过与邻小区基站的通信获得邻小区***所使 用带宽和频点的情况。
步骤 S804, 根据实际的使用场景， 服务小区基站指示其接入的移动台进 行合适的测量。
服务小区基站根据步骤 S802 获得的信息来决定接入其内的移动台应该 如何进行测量。
服务小区基站通过下面公式计算出测量频点的数目和每个测量频点的测 量带宽：
BWn = B I N
N = (Bserv -Wgap) IBneigh 。 然后， 基站将测量信息发送给移动台， 信息可通过 SIB发送， 也可以通 过控制信令的方式进行控制， 发送的内容可以是服务小区的中心频率和中心 载频处的偏置加每频点测量带宽的形式，或者测量频点 EARFCN加每频点测 量带宽的形式。
步骤 S806, 服务小区中的移动台根据步骤 S804中基站指示的测量方式 进行测量。 为维持与网络的合适连接， 移动台需要进行测量和上报过程， 测 量的对象是同频、 异频或异***的 CRS或 CSI-RS ( Channel State Information Reference Signal, 信道状态信息参考信号） ， 将各个测量频点内的测量值做 平均所得的平均值作为一次测量的值， 再经过层 1和层 3的滤波， 将处理后 的测量值上报给服务小区基站， 这样网络就能对其进行适当的调度和服务。
下面结合图 10A-10B所示的场景， 以测量总带宽为 6RB为例， 对本发明 实施例服务小区基站进行测量带宽选择的方法进行说明。 图 9为本实施例中 基站针对不同的小区场景进行测量带宽选择的流程图， 如图 9所示， 该流程 主要包括以下步骤。
步骤 S901, 服务小区基站通过网络与邻小区进行通信， 获得所述服务小 区的邻小区频带使用情况。
步骤 S902, 服务小区基站判断服务小区载频与邻小区载频是否相同， 如 果是， 则执行步骤 S903, 如果否， 则执行步骤 S904。
步骤 S903, 邻小区和服务小区使用的是相同的频带， 小区部署场景如图 10A所示， 服务小区基站根据下面公式进行计算， 确定其接入的移动台适合 普通的窄带测量， 测量带宽为载波中心 6RB:
BWn=B IN
NU gJ/B气 步骤 S904, 邻小区和服务小区使用的是不同的频带， 服务小区基站判断 邻小区的频带， 如果邻小区的频带为 5M, 则执行步骤 S905, 如果邻小区的 频带为 3M,则执行步骤 S906,如果邻小区的频带为 1.4M,则执行步骤 S907。
步骤 S905, 邻小区的频带为 5M, 小区部署场景如图 10B所示， 保护带 宽总和为 0.5MHz, 服务小区基站根据下面公式进行计算：
BWn=B IN
NU gJ/B气 基站判断其接入的移动台适合进行多频点的窄带测量， 测量频点数为 2, 每频点测量带宽为 3RB, 为一种（3+3) RB的方式， 测量带宽被分成两份， 每一份为 3RB, 分别处在邻小区载波中心 3RB。
步骤 S906, 邻小区频带为 3M, 小区部署场景如图 10C所示， 保护带宽 总和为 0.3+0.3=0.6MHz, 服务小区基站根据下面公式进行计算：
BWn=B IN
NU gJ/B气 基站判断其接入的移动台适合进行多频点的窄带测量， 测量频点数为 3, 每频点测量带宽为 2RB, 为一种（2+2+2 )RB的方式， 测量带宽被分成三份， 每一份为 2RB, 分别处在邻小区载波中心 2RB。
步骤 S907, 邻小区频带为 1.4M, 小区部署场景如图 10D所示， 保护带 宽总和为 0.14+0.14+0.14+0.14+0.14=0.7MHz, 服务小区基站根据下面公式进 行计算：
BWn = B IN
NU gJ /B气 基站判断其接入的移动台适合进行多频点的窄带测量， 测量频点数为 6, 每频点测量带宽为 1RB, 为一种（ 1+1+1+1+1+1 ) RB的方式， 测量带宽被分 成六份， 每一份为 1RB, 分别处在邻小区载波中心 1RB。
步骤 S908, 服务小区基站将选择的测量带宽及测量频点通过信令通知移 动台。
步骤 S909, 服务小区中的移动台根据基站指示的测量方式进行测量。 在本发明实施例中， 移动台根据服务小区基站指示进行正常的测量。 每 隔一定的测量周期（例如 40ms )进行一次测量， 移动台每次执行测量时， 可 以在基站指示的各个测量频点上， 按照基站所指示的该测量频点上的测量带 宽进行测量。 层 1滤波将多次连续测量（例如 5次） 的平均值作为这一段时 间窗内的测量值， 再经过层 3滤波将前一次上>¾的测量结果与这一次测量值 进行加权作为这次上报的测量值， 移动台将这个测量值上报给基站以完成整 个测量动作。
通过本发明实施例提供的上述技术方案， ***能够根据不同的小区部署 场景通过网络侧的控制进行 RRM测量带宽选择。 将测量的频段尽量分散到 整个***带宽内， 充分反映整个***带宽内的干扰情况， 尽可能获得测量上 的频域分集， 反映较准确的***当前信道情况， 解决原先只在中心 6RB上进 行测量时因为部署场景的不同可能存在测量失准的问题。这种更灵活的 RRM 测量带宽选择方式能够更好地适应目前日益复杂的移动传播环境， 从而保证 测量的准确性。
