Description

一种干扰检测方法、 装置和***

技术领域
本发明涉及通信技术领域， 特别涉及一种干扰检测方法、 装置和***。
背景技术
在目前的蜂窝通信***中，各个基站的站址都是经过网络规划以确保不同 的基站之间发生的干扰在可接受范围之内。 随着通信技术的发展， 更多类型的 频媒被应用到蜂窝通信***中； 因此相同频率使用不同的无线接入技术，相邻 频率使用相同或不同的接入技术都称为可能。各种类型的频媒被应用到蜂窝通 信***后的网络布局使得基站间的干扰共存更为复杂，因此需要新的干扰检测 和干扰共存的方案。

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。 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， 所描述的实施例仅仅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。
本发明实施例的应用场景为采用动态频谱共享 （ Dynamic spectrum sharing, DSS )技术的低功率节点 （Lower power node, LPN )和宏小区之间 的干扰问题，或者 LPN节点之间的干扰问题。 LPN可以为微微蜂窝 Pico小区， 微 micro小区， 中继 relay、 家庭基站 HeNB ( HNB )等。 本发明实施例为了方 便描述， 以 LPN和宏基站间的干扰为例进行描述， LPN之间的干扰问题， 或 者宏基站间的干扰问题也可以采用同样方法；在实施例的介绍中以宏基站作为 测量基站即执行干扰测量的基站， 也可以称为被干扰基站； LPN作为干扰基 站即造成干扰的基站； 需要说明的是， 测量基站也可以是 LPN, 对此本发明 实施例其它位置不再——说明。
由于 DSS技术的采用，在一个宏基站内部可能会产生 N个 LPN使用频分 复用 （Frequent Division Duplex, FDD )上行（Uplink, UL ) 资源进行下行信 号的发送， 该发射信号会被宏基站下的小区和相邻的多个 LPN接收到， 从而 造成对宏小区或相邻的 LPN的上行的干扰。
本发明实施例 DSS应用场景如图 1A所示， 其中宏基站用 eNB表示， 在 eNB覆盖范围内有多个 LPN。 干扰场景可以分为同频干扰， 异频干扰， 异系 统干扰等不同的场景。
其中同频干扰， 异频干扰和异***干扰的频谱示意图如图 1B到图 1D所 示：
图 1B是同频的场景， 图 1C是异频的场景。 宏基站 eNB 1是提供上行资 源给 LPN的基站， 宏基站 eNB2是 LPN的相邻宏基站。 eNBl,eNB2和 LPN 的下行都白框来表示。 宏基站 eNB 1 , eNB2和 LPN的上行频段上的上行子帧 都用斜线阴影表示。 LPN在上行频段上的下行子帧用网格阴影所示。 图 1D是异***的场景， 宏基站 eNBl是提供上行资源给 LPN的基站， 宏 基站 eNB2是 LPN的相邻宏基站。 其中宏基站 eNBl和 LPN可以是相同的接 入技术， 也可以是不同的接入技术， 本发明实施例是以宏基站 eNBl 和 LPN 采用相同接入技术的情况为例的， 当属于不同接入技术时， 所采用的方法也是 类似的， 不在本发明实施例中具体说明。 宏基站 eNB2采用和 LPN不同的接 入技术。 在 eNBl和 LPN的下行都用白框来表示， eNBl和 LPN的上行频段 上的上行子帧都用斜线阴影表示。 LPN在上行频段上的下行子帧用网格阴影 所示。
在上述场景中的干扰协调中各个涉及到的节点以及相应的操作如图 1E所 示： 其中有 4个典型的网络单元：
网络单元 0为： 提供资源给 LPN小区的宏基站 eNBl和其下的 UEs组成 了网络单元 0,在本文档中，提供资源的基站 eNBl和 LPN小区之间可以通过 干扰规避方式来解决干扰问题。 所以对于网络单元 0不涉及到对于网络单元 1 的干扰检测和干扰处理的问题。
网络单元 1 : LPN1和其下的 UEs形成了网络单元 1 , 其对相邻的 LPN 小区（网络单元 2)或者宏基站 eNB2(网络单元 3)形成干扰， 网络单元 1可以为 干扰基站。
网络单元 2为： 与 LPN的时分复用 （ Time Division Duplex, TDD ) 小区 相邻的 LPN小区 （LPN2 ) , 该 LPN2和其下的 UEs构成了网络单元 2, 需要 检测其被相邻的 LPN1的干扰情况， 并进行干扰处理， 所以网络单元 2可以为 测量基站；
网络单元 3:是与 LPN的 TDD小区相邻的宏小区，该宏小区可以是同频， 异频或异***的小区。 该宏小区和宏小区下的 UEs构成了网络单元 3 , 需要检 测网络单元 1对其的干扰以及需要跟网络单元 1间进行干扰的管理，网络单元 3也可以为测量基站。
本发明实施例主要解决的是网络单元 1对于网络单元 2之间的干扰检测和 干扰处理的方法，或者， 网络单元 1对于和网络单元 3之间的干扰检测以及干 扰处理的方法。本发明实施例以网络单元 1对网络单元 3之间的干扰检测和干 扰处理来阐述本发明实施例方案，网络单元 1对于和网络单元 2之间的干扰检 测以及干扰处理也可采用本发明实施例的方案， 就不具体——赘述。
本发明实施例对于干扰的检测可以使用高层的测量量，比如参考符号接收 功率 ( Reference signal received power, RSRP ) ,参考符号的接收质量 ( Reference signal received quality, RSRQ )以及接收信号强度指示 ( Received signal strength indication, RSSI )测量, 或物理层的测量量， 如 CQI测量或者 SRS测量。 其 他与上述测量能达到相同效果的测量本发明实施例对此并不予限定，因此以上 的测量量的举例不应理解为对本发明实施例的限定；在本发明实施例中将这些 量通常为测量参考符号的接收质量值。
另外需要说明的是：除了 DSS的场景外，任何在基站的接收频带，如 FDD UL频段上或 FDD上行频段附近有下行发送的情况都可以采用本发明实施的 方案， 其具体可以为：
FDD UL频段上或者 FDD UL频段附近（按照 RAN4的性能规范，在隔离 带范围内即为有干扰的邻频， 比如〜 30MHz附近， 或者 50MHz等， 具体数据 由 RAN4仿真决定 )的其他频段上有 FDD下行链路 ( Downlink, DL )的发送 或者 TDD DL的发送， 或者有其他无线接入技术的发射。
TDD频段上或 TDD频段附近（按照 RAN4的性能规范，在隔离带范围内 即为有干扰的邻频， 比如〜 30MHz附近， 或者 50MHz等， 具体数据由 RAN4 仿真决定） 的其他频段上的 TDD UL对应的时隙上有 DL发射， DL发射包括 相同接入技术 FDD制式或非 FDD制式， 或不同的接入技术。
本发明实施例提供了一种干扰检测方法， 如图 2A所示， 包括： 201A: 测量基站获取干扰基站的测量参考符号及上述测量参考符号的配 置信息；

另外测量参考符号还可以是其他的用于测量的参考符号，这些参考符号分 布在干扰基站的上行子帧上或下行子帧上的一些物理无线资源块 （Physical Radio block, PRB)上。测量参考符号所占用的位置可以反映干扰基站发送的测 量信号的情况。

202B: 上述干扰基站将上述测量参考符号的配置信息发送给测量基站， 以使得上述测量基站根据上述配置信息检测上述干扰基站的测量参考符号的 接收质量值。
与测量基站侧的实现方案对应地， 本实施例中：
上述的测量参考符号包括以下之一： 下行子帧上的公共参考符号， 下行子 帧上的信道探测参考符号， 上行子帧上的公共参考符号， 上行子帧上的信道探 测参考符号。
另外测量参考符号还可以是其他的用于测量的参考符号，这些参考符号分 布在干扰基站的上行子帧上或下行子帧上的一些物理无线资源块 （Physical Radio block, PRB)上。测量参考符号所占用的位置可以反映干扰基站发送的测 量信号的情况。
可选地，上述干扰基站将上述测量参考符号的配置信息发送给测量基站之 前， 还包括： 上述干扰基站接收到测量基站发送的测量请求消息； 上述干扰基 站根据上述测量请求消息向上述测量基站发送上述测量参考符号及上述测量 参考符号的配置信息。
可选地， 上述配置信息中包括至少以下信息之一： 上述测量参考符号的位 置指示信息， 上述测量参考符号的带宽配置、 上述测量参考符号的子帧配置、 上述测量参考符号的上报配置、 上述测量参考符号发射功率配置；
其中， 上述位置指示信息为：
指示测量上述测量参考符号所使用的中心频率和测量带宽的信息； 或者 指示测量上述测量参考符号所使用的起始位置和终止位置的信息； 或者 指示测量上述测量参考符号所使用的起始位置和偏移量 offset的信息。 方案一、本发明实施例提供了一种干扰检测方法，方案一中测量基站 eNB2 进行干扰基站 LPN 的下行子帧上的公共参考符号 （Common Reference Symbols, CRS ) 的检测， 测量基站作为一个特殊的 UE, 对干扰基站 LPN进 行干扰检测。 方案一的流程可以如图 3A所示， 包括： 测量基站 eNB2发现启 动干扰检测的条件符合（例如检测到本测量基站的调度性能降低， 或者本测量 基站的信号质量变差， 比如 UE上报的本基站的公共参考符号的信号质量低于 设定门限（RSRQ门限）； 启动测量干扰基站 LPN; 保存&处理测量结果， 测 量基站 eNB2进行干扰处理， 测量基站 eNB2在执行干扰检测的过程中可以划 分为三个步骤： 步骤一： 首先测量基站 eNB2进行了下行测量的配置（生成测量参考符号 的配置信息） ， 此时测量实体为测量基站 eNB2, 而不是传统的下行测量的执 行实体 UE, 其具体配置包括：
测量量： 基站 eNB2可以支持 RSRP, RSRQ和 RSSI的测量。
测量目标： 被测量小区频点和带宽， 被测量小区的标识（Identity, id ) , 被测量小区的上下行的配置， 被测量小区的偏置量， 被测量小区的 MBSFN配 置或空白帧配置，被测量小区的天线配置等， 这些信息可以通过目前已有的接 口 （比如： 长期演进（ Long Term Evolution, LTE ) 中的 X2口， 或通用移动 通信*** ( Universal Mobile Telecommunications System, UMTS ) 的 Iur口 , 或其他***的类似接口 )获得。 但是对于干扰类的测量， 需要测量实体停留在 被干扰基站的工作频带范围内进行干扰小区的信号的测量。所以测量目标中的 被测量小区的中心频点可以设置为被干扰小区的中心频点，或者测量目标中的 被测量小区的中心频点位于被干扰小区的干扰频带范围内。此时， 测量目标中 的被测量小区的中心频点可以按照一定的类度（比如 LTE***而言， 可以按 照 6RB的类度进行） 自治的搜索。
另夕卜，如果测量基站通过一定的方法确定了干扰频带， 则测量目标中的测 量参考符号的位置指示信息， 测量参考符号的带宽配置， 测量参考符号的子帧 配置都会体现在测量目标中，以指示测量基站对这些物理资源块上的测量参考 符号进行干扰检测。
测量事件的配置： 原则上测量基站 eNB2可以支持全部 UE支持的测量事 件， 比如在 LTE中， 从 A1-A5, B1和 B2等； 在干扰检测的场景下， 主要的 是检测 RSRQ值是否高于或者低于设定的门限值。 由于测量目的不同，现有技 术的下行测量是为了移动性， 而干扰检测的下行测量是为了干扰测量， 所以类 似事件含义的事件， 其使用的阈值各不相同。
那么， 测量基站进行检测的场景下， 因为 LPN和干扰基站都是静止的基 站， 所以， 测量的结果会比较稳定， 只受到环境的扰动。 所以检测者的速率为 低速， 而且在上报时， 可以考虑不适用 （ Time To Trigger, TTT )参数测量结 果的处理： 对于物理层上报到高层的测量结果， 测量基站 eNB2可以进行层三 Layer 3 , L3过滤操作， 基站使用的 L3过滤的参数可以按照低速 UE的参数来 配置。
步骤二： 测量基站 eNB2启动对于 LPN的干扰的测量。 对于何时启动对 于邻区 LPN (干扰基站 )的测量可能有两种方式， 一种是测量基站 eNB2的内 部实现， 测量基站 eNB2根据基站上小区的调度性能的下降， 比如在 LPN下 行发射时隙 , eNB2上的数据的误块率（ Block Error Rate, BLER )超过设定值， 则测量基站 eNB2判决是 LPN引起干扰。 或者在变更 LPN配置后不久， eNB2 上的数据的 BLER超过设定值， 则 eNB2判断是 LPN引起干扰， 则启动对于 LPN的测量。另外一种方式可以是测量基站 eNB2检测本基站的 RSRQ值，具 体可以为不区分 LPN下行子帧对应的子帧和 LPN 的上行子帧对应的子帧的 CRS检测， 在这种情况下， 如果本基站的 RSRQ值低于设定的门限值， 则启 动对于 LPN的 RSRQ的测量。 或者测量基站 eNB2在检测本基站的 RSRQ值 时， 区分 LPN下行子帧对应的子帧和 LPN的上行子帧对应的子帧的 CRS检
LPN的 RSRQ的测量。
步骤三： 测量基站 eNB2对于 LPN的下行干扰的检测， 只检测该下行子 帧上的 RSRQ值。 当所检测的 RSRQ的值高于设定的阈值时， 测量基站 eNB2 可能保存该测量结果， 并启动和 LPN的干扰处理流程。
当 LPN只有部分频带干扰测量基站 eNB2时， 如前上述， 测量基站 eNB2 可以通过目前已经存在的接口获得 LPN的如下配置信息： 小区频点和带宽， 小区的 id, 小区的上下行的配置， 小区的偏置量， 小区的多媒体广播多播业务 单频网 ( Multimedia Broadcast Multicast Service over the single frequency network, MBSFN ) 配置或空白帧配置， 小区的天线配置等。 测量基站 eNB2 可以根据 RAN4的性能规定， 获知 LPN的哪部分频带对测量基站 eNB2有干 扰。 或者测量基站 eNB2在本基站上对 LPN的全频带的 CRS进行测量， 然后 分析那些频带的 CRS 的干扰值比较大， 然后确定那部分频带对该测量基站 eNB2有干扰。
测量基站 eNB2对于部分频带的测量有 2种实现方式， 一种是修改 RSRQ 测量， 支持窄带的 RSRQ测量。 或者修改 CQI, 对 CQI的测量结果进行 L3过 滤处理。
方式一： 为了准确测量 LPN 上的对测量基站 eNB2造成干扰的频带的 RSRQ值， 则需要对部分的公共参考符号 （common reference signaling, CRS ) 符号而不是全部的 CRS符号进行测量。
如图 3B所示， 测量基站 eNB2上行的非干扰频带区域， 以及干扰频带区 域； LPN上下行非干扰频带区域， 以及干扰频带区域。
为了通知部分 CRS的位置， 可以采用中心频率 +带宽的方式（即： 指示测 量上述测量参考符号所使用的中心频率和测量带宽的信息 )， 或者频率起始分 别指示的方法（即： 指示测量上述测量参考符号所使用的起始位置和终止位置 的信息）， 或者频率起 +offset的方式（即： 指示测量上述测量参考符号所使用 的起始位置和偏移量 offset的信息 )表达。
当被干扰频带或干扰频带为部分频带时，在此测量目标中指示需要测量的 CRS的范围， 比如：
选项一： CRS的中心频率 +测量的 CRS带宽的方法
MeasObjectEUTRA ::= SEQUENCE {
carrierFreq ARFCN-ValueEUTRA,
allowedMeasBandwidth AllowedMeasBandwidth,
presenceAntennaPort 1 PresenceAntennaPortl ,
measured— carrierFreq ARFCN-ValueEUTRA, (fc of CC or fc of CRS)
measured— bandwidth Measured— bandwidth or measured PRBs (bandwidth of partial carrier or CRS)
或者， 选项二： 测量的 CRS的起始位置和终止位置
MeasObjectEUTRA ::= SEQUENCE {
carrierFreq ARFCN-ValueEUTRA,
allowedMeasBandwidth AllowedMeasBandwidth,
presenceAntennaPort 1 PresenceAntennaPort 1 ,
measured— carrierFreq_start ARFCN-ValueEUTRA, measured— carrierFreq_stop ARFCN-ValueEUTRA, 或者， 选项三： 测量的 CRS的起始位置 +offset
MeasObjectEUTRA ::= SEQUENCE {
carrierFreq ARFCN-ValueEUTRA,
allowedMeasBandwidth AllowedMeasBandwidth,
presenceAntennaPort 1 PresenceAntennaPort 1 ,
measured— carrierFreq_start ARFCN-ValueEUTRA, measured— carrierFreq_offset Measured— bandwidth or measured PRBs
在选项三中， 如果测量的 CRS的起始位置是低频， 则 offset值为正值， 如果测量的 CRS的测量位置为高频， 则 offset值为负值。
除了上述方法外， UE还可以基于设定的类度， 比如 6RB或 1.25MHz的 测量带宽，在服务小区的基站范围内从低频到高频或者从高频到低频进行设定 类度的同频或异频测量。
在这种情况下， 为了减小产生的异频测量， 而且因为即使基站值检测部分 的 CRS符号， 测量基站 eNB2也可以不改变测量频点帧控制字段 fc的配置， 而只是修改 CRS频带的频点， 保持测量为同频测量。 或者测量基站 eNB2将 其接收频带范围内的测量都视为同频测量。 或者 UE保持测量的 fc是服务小区的中心频点，检测服务小区全部频带范 围内的相邻小区的导频信号， 并对干扰信号质量超过阈值部分的干扰信号（比 如图 3B中的干扰频带区域的 CRS符号 ) 的测量结果进行 L3过滤操作， 并进 行据此进行干扰的评估和上报。 对于干扰信号质量低于阈值部分的干扰信号 (比如图 3B中的非干扰频带区域的 CRS符号）不进行 L3过滤操作， 不作为 干扰信号进行评估和事件的上报。
上述的并对干扰信号质量超过阈值部分的干扰信号（比如图 3B中的干扰 频带区域的 CRS符号）也可以被确定为干扰频带， 测量基站对该干扰频带的 信号进行层 3过滤操作， 并据此进行干扰的评估和上报。
方式二： 测量基站 eNB2对于部分被干扰频带的测量，可以采用 CQI测量 的方式。
首先： 启动对于 LPN的干扰的测量。 对于何时启动对于邻区 LPN的测量 可能有两种方式， 一种是测量基站 eNB2的内部实现， eNB2根据基站上小区 的调度性能的下降， 比如 LPN下行发射时隙， eNB2上的数据的 BLER超过设 定值， 则 eNB2判决是 LPN引起干扰。 或者在变更 LPN配置后不久， eNB2 上的数据的 BLER超过设定值， 则 eNB2判断是 LPN引起干扰， 则启动对于 LPN的此类昂。另外一种方式可以是 eNB2检测本基站的 RSRQ值，具体可以 为不区分 LPN下行子帧对应的子帧和 LPN的上行子帧对应的子帧的 CRS检 测， 在这种情况下， 如果本基站的 RSRQ值低于设定的门限值， 则启动对于 LPN的 RSRQ的测量。 或者 eNB2在检测本基站的 RSRQ值时， 区分 LPN下 行子帧对应的子帧和 LPN的上行子帧对应的子帧的 CRS检测， 当 LPN下行 子帧对应的 RSRQ的检测低于设定的门限值时， 则启动对于 LPN的 RSRQ的 测量。
然后： 将 CQI的测量带宽配置为干扰区域的带宽， 此时的干扰区域的带 宽， 可以为相邻小区的全部带宽或者相邻小区的部分带宽。 测量基站 eNB2像 UE—样进行指定带宽的 CQI测量。 因为 CQI是支持调度的动态的测量结果， 为了得到干扰情况的长期的测量结果，测量基站 eNB2可以把该动态的测量结 果进行 L3过滤， 得到过滤后的高层的测量结果。
方案二： 本方案中测量基站对干扰基站 LPN的下行子帧上的信道探测参 考符号进行检测， 基站将 LPN当成特殊的 UE进行信道探测参考符号的检测。 如图 4A所示， eNB2检测 LPN下行子帧上发送的信道探测参考符号 (Sounding Reference signal, SRS)流程可以包括： 测量基站 eNB2检测本基站下的小区的 调度性能变差， 或者调度性能差过一定的门限值， 则 eNB2 向干扰基站 LPN 发送信道探测参考符号 SRS的调度请求， 用于请求 LPN启动用于干扰检测的 下行子帧上的信道探测参考符号的调度， LPN接收到调度请求后执行 SRS调 度。 当 eNB2发送信道探测参考符号的调度请求信息到 LPN后， eNB2可以配 置基于信道探测参考符号测量的配置信息。 该配置信息可以包括：
测量量： 类似于 RSRP, RSRQ和 RSSI的测量量。
测量目标： 被测量小区频点和带宽， 被测量小区的标识（Identity, id ) , 被测量小区的上下行的配置， 被测量小区的偏置量， 被测量小区的 MBSFN配 置或空白帧配置，被测量小区的天线配置等， 这些信息可以通过目前已有的接 口 （比如： 长期演进（ Long Term Evolution, LTE ) 中的 X2口， 或通用移动 通信*** ( Universal Mobile Telecommunications System, UMTS ) 的 Iur口 , 或其他***的类似接口）获得。 但是对于干扰类的测量， 需要测量实体停留在 被干扰基站的工作频带范围内进行干扰小区的信号的测量。所以测量目标中的 被测量小区的中心频点可以设置为被干扰小区的中心频点，或者测量目标中的 被测量小区的中心频点位于被干扰小区的干扰频带范围内。此时， 测量目标中 的被测量小区的中心频点可以按照一定的类度（比如 LTE***而言， 可以按 照 6RB的类度进行） 自治的搜索。 另外， 如果测量基站通过一定的方法确定 了干扰频带， 则测量目标中的测量参考符号的位置指示信息， 测量参考符号的 带宽配置， 测量参考符号的子帧配置都会体现在测量目标中， 以指示测量基站 对这些物理资源块上的测量参考符号进行干扰检测。
测量事件的配置： 测量基站 eNB2可以支持全部下行测量的测量事件， 比 如在 LTE中， 从 A1-A5, B1和 B2等； 在方案二， 方案三中， 类似的事件定 义可以用来表明基于下行子帧上的信道探测参考符号或上行子帧上信道探测 参考符号检测出的相邻小区的干扰触发情况。这些上行测量事件的配置和下行 事件的配置类似， 即事件的含义相同， 比如服务小区 (测量基站)或相邻小区 (干 扰基站)的接收质量值与绝对阈值或相对阈值 (服务小区（测量基站)与相邻小区 (干扰基站)的接收质量值进行比较， 并增加相对偏置量)进行比较等。 由于测量 目的不同，现有技术的下行测量是为了移动性， 而上行干扰检测是为了干扰测 量， 所以类似事件含义的事件， 其使用的阈值各不相同。
测量结果的处理： 对于物理层上报到高层的测量结果， 测量基站 eNB2可 以进行层三 Layer 3 , L3过滤操作， 基站使用的 L3过滤的参数可以按照低速 UE的参数来配置。
LPN 收到该信道探测参考符号调度请求信息后， 启动用于干扰检测的下 行子帧上的信道探测参考符号 SRS, 并把该信道探测参考符号 SRS的配置信 息， 包括调度信息发送给 eNB2,使其进行基于信道探测参考符号的干扰检测； eNB2收到 LPN的信道探测参考符号的调度信息后，启动基于信道探测参 考符号的干扰检测。如果所检测的信道探测参考符号的测量量满足设定的事件 门限时， 则 eNB2保存和处理该测量结果， 并发起和 LPN的干扰处理过程。
LPN在下行子帧上发送信道探测参考符号。为了使测量基站 eNB2能像检 测 UE的信道探测参考符号 （ Sounding Reference signal, SRS )那样检测 LPN 的下行信道质量， 在 LPN的下行子帧上需要调度和 UE的信道探测参考符号 相同的资源， 并发送和 UE上行相同的信道探测参考符号， 但是该信道探测参 考符号的发射功率和 LPN的下行子帧上的公共参考符号 CRS是一样的。信道 探测参考符号位于一个 UL子帧的最后一个符号，但是其占用的带宽是***可 以配置的。 为了使测量基站 eNB2能够检测该 LPN的信道探测参考符号 SRS 的符号， LPN需要将信道探测参考符号的配置信息通知给 eNB2。具体流程为： 步骤一： LPN在下行子帧上调度信道探测参考符号， 具体可如图 4B-1至 图 4B-3所示， 单天线口， 2天线口和 4天线口情况下的 LPN的下行子帧上的 SRS的调度位置：
4B-1至图 4B-3依次为： 单天线端口： One antenna port; 两个天线端口： Two antenna ports;四个天线端口： Four antenna ports; 禺数日†隙:： even-numbered slots； 奇数 H†隙:： odd-numbered slots；
从上到下依次为： 天线端口 0: Antenna port 0; 天线端口 1 : Antenna port 1 ; 天线端口 2: Antenna port 2; 天线端口 3: Antenna port 3;
黑色的方块为： 资源元素 ( K, L ) ： Resource element (k,l);
空白的方块表示：不用于传输此天线端口： Not used for transmission on this antenna port;
标有为 的方块表示为： 这个天线端口参考符号： Reference symbols on this antenna port„ 的最后一个符号上， 而且每个信道探测参考符号隔一个子载波。 该干扰基站 LPN 的下行子帧上的信道探测参考符号的配置信息包括： 信道探测参考符号 的带宽配置 , 信道探测参考符号的子帧配置和信道探测参考符号的上报配置。 而且需要通知 eNB2该信道探测参考符号发送子帧配置。 LPN在 SRS上的发 送功率和其公共参考符号上 CRS上的发射功率相同。
步骤二： 测量基站 eNB2启动对 LPN的干扰检测， 方法和方案一的步骤 二中启动对 LPN测量相同， 不在此赘述。
步骤三： 测量基站 eNB2通知 LPN要启动对 LPN的测量， 则 eNB2通过 LPN和 eNB2间的直接或者间接接口发送测量请求。在该测量请求中 eNB2通 知 LPN要测量 LPN的干扰。
步骤四： LPN 收到该测量请求的信息后， 启动对下行子帧上发送的信道 探测参考符号的调度， 并把该调度配置发送给 eNB2; 信道探测参考符号的调 度配置包括:信道探测参考符号的带宽配置， 信道探测参考符号的子帧配置和 信道探测参考符号的上报配置。 为了支持 eNB2的测量， LPN还需要将信道探 测参考符号上的发射功率配置发送给 eNB2。
步骤五： 测量基站 eNB2对 LPN上信道探测参考符号进行检测。 因为干 扰是一个长期的测量结果， eNB2需要对测量的信道探测参考符号的值进行 L3 过滤操作，具体的 L3过滤的算法和 UE的 L3过滤相似。 同样因为对高层测量 的支持， 在 LPN的下行子帧上 SRS的调度周期也可以设置的比较长， 只要满 足 RAN4对于高层测量的需求即可。
方案三： 本方案中干扰基站 LPN在 UL子帧上发送 LPN的信道探测参考 符号， 该信道探测参考符号使用和下行子帧上的公共参考符号 CRS相同的发 射功率。
具体的操作流程和方案二相似， 不同之处在于：
步骤一： 干扰基站 LPN在上行子帧上调度类似于 UE上行的信道探测参 考符号， 具体可如： UL子帧上的信道探测参考符号的调度位置如图 4C所示 的单载波频分多址 ( Single Carrier Frequency Division Multiple Access , SC-FDMA )块以及子载波。 信道探测参考符号被调度在每个无线资源块 RB 的最后一个符号上， 而且每个信道探测参考符号隔一个子载波。 该 LPN的上 行子帧上的信道探测参考符号的配置信息包括： 信道探测参考符号的带宽配 置 , 信道探测参考符号的子帧配置和信道探测参考符号的上报配置。
而且需要通知 eNB2该信道探测参考符号发送子帧配置。 LPN在信道探测 参考符号上的发送功率和其 CRS上的发射功率相同。 LPN的信道探测参考符 号的配置和普通的 UE在上行子帧上的 SRS配置类似。信道探测参考符号位于 一个 UL子帧的最后一个符号， 但是其占用的带宽是***可以配置的。
本方案步骤二和步骤三与方案二的步骤二和步骤三相同。
步骤四： LPN 收到该信息后， 启动对上行子帧上发送的信道探测参考符 号的调度， 并把信道探测参考符号的调度配置发送给 eNB2; 信道探测参考符 号的调度配置包括:信道探测参考符号的带宽配置， 信道探测参考符号的子帧 配置和信道探测参考符号的上报配置。而且需要通知 eNB2该 SRS发送子帧配 置以及发射功率的配置。
本方案步骤五的处理和方案二的步骤五相同。
方案四： 本方案干扰基站 LPN在 UL子帧上发送新定义的上行公共参考 符号， 测量基站 eNB2检测新的上行公共参考符号， 进行 LPN上行的测量。 其中上行子帧上新设定的公共参考符号的位置可以参考 DL公共参考符号的位 置。参考符号在整个 PRB内均衡的占用一些资源要素（ resource element, RE )。 可以采用和信道探测参考符号类似的特定符号上进行。上行公共符号的设定如 图 5所示的业务码频分多址 ( single carrier Frequency Division Multiple Access, SC-FDMA )块以及子载波。 LPN可以在上行子帧上发送上行公共符号， 该上 行公共符号上的发射功率和下行的 CRS的发射功率相同；分布在标 Ro的位置。
测量的方法可以和方案一中的下行链路（Downlink, DL ) 测量类似， 只 是测量的方向变为上行测量。
步骤一： 首先测量基站 eNB2进行了上行测量的配置， 其具体配置包括： 测量量： 基站 eNB2可以支持上行的 RSRP, 上行的 RSRQ和上行的 RSSI 的测量。 该测量基于上述新设定的上行 CRS参考符号。
测量目标： 被测量小区频点和带宽， 被测量小区的标识（Identity, id ) , 被测量小区的上下行的配置， 被测量小区的偏置量， 被测量小区的 MBSFN配 置或空白帧配置，被测量小区的天线配置等， 这些信息可以通过目前已有的接 口 （比如： 长期演进（ Long Term Evolution, LTE ) 中的 X2口， 或通用移动 通信*** ( Universal Mobile Telecommunications System, UMTS ) 的 Iur口 , 或其他***的类似接口）获得。 但是对于干扰类的测量， 需要测量实体停留在 被干扰基站的工作频带范围内进行干扰小区的信号的测量。所以测量目标中的 被测量小区的中心频点可以设置为被干扰小区的中心频点，或者测量目标中的 被测量小区的中心频点位于被干扰小区的干扰频带范围内。此时， 测量目标中 的被测量小区的中心频点可以按照一定的类度（比如 LTE***而言， 可以按 照 6RB的类度进行 ) 自治的搜索。
另夕卜，如果测量基站通过一定的方法确定了干扰频带， 则测量目标中的测 量参考符号的位置指示信息， 测量参考符号的带宽配置， 测量参考符号的子帧 配置都会体现在测量目标中，以指示测量基站对这些物理资源块上的测量参考 符号进行干扰检测。
测量事件的配置： 测量基站 eNB2上行的公共导频符号的测量可以支持 全部的下行测量事件， 比如在 LTE中， 从 A1-A5, B1和 B2等。 但是由于是 上行的测量事件， 该事件可以进行重命名： 比如 C 1 -C5 , 和 D 1和 D2 , 其中 C 1 -C5可以和 Al -A5对应， D 1和 D2可以和 B 1和 B2对应， 相对应的事件具 有类型的含义， 指示由于测量目的的不同， 可以使用不同的阈值。 在干扰检测 的场景下，主要的是检测 RSRQ值是否高于或者低于设定的门限值。则基站进 行检测的场景下， 因为 LPN和干扰基站都是静止的基站， 所以， 测量的结果 会比较稳定， 只收到环境的扰动。 所以检测者的速率为低速， 而且在上报时， 可以考虑不适用 TTT参数。
测量结果的处理： 对于物理层上报到高层的测量结果， eNB2可以进行 L3 过滤操作， 基站使用的 L3过滤的参数可以按照低速 UE的参数来配置。
步骤二和步骤三和方案一中的步骤二以及步骤三相同。上行公共参考符号 的测量支持指定带宽的 L3的测量。 该指定的带宽可以和方案一中步骤三的指 示方式类似， 也可以使用几种固定的带宽类度， 比如 6RB, 或 1.25M等。 在从方案二到方案四的干扰检测中，测量基站也需要检测干扰基站的干扰 频带， 其检测的方法可以为下面的方式之一：
基于协议性能规范的干扰范围和干扰基站使用的频带范围，确定测量基站 的干扰频带的范围， 获取该干扰频带内的干扰基站的接收质量；
基于本基站的全频带进行测量，基于不同子频带的测量结果， 判决干扰频 带的位置， 获取该干扰频带内的干扰基站的接收质量。
检测本基站的全频带上的干扰基站的信道质量，信道质量超过阈值部分的 子频带为干扰频带， 获取该干扰频带内的干扰基站的接收质量。
对于上述已经确定出的干扰频带的指示， 可以采用下面的方法之一： 测量的中心频率和测量带宽设定的方法进行测量； 或者，
测量的起始位置和终止位置分别指示的方法进行测量； 或者，
测量的起始位置和 offset设定的方法进行测量； 或者，

进一步地， 在上述检测干扰基站的小区信号接收质量之后， 还包括： 对上述干扰基站的小区信号接收质量进行层三 L3过滤， 并根据上述过滤 后的值进行干扰的评估。
上述配置信息中包括的信息可以参考前四个方案， 在此不再——赘述。 方案五： 该方案的示意图如图 6C所示， 本方案中， 测量基站（eNB2 )选 择其服务的部分 UE进行 LPN基站的干扰的检测， 综合 N个 UE的测量结果， 得到 LPN基站的干扰信息。
被选择的 MUE ( Macro UE )需要是能在 FDD UL上进行接收的 UE。 但 是 MUE和服务基站 (测量基站)的接收位置不同，所以其检测的结果可能不准。 而且如果采用 MUE的检测，则该 MUE需要离基站很近。需要选择合适的 MUE 为基站做检测。 MUE的选择和 LPN的干扰结果可以采用如下的方法：
MUE选择的方法： 根据 MUE到服务基站 (测量基站)的路损 (Pathloss,PL) 值来选择 MUE。 MUE到服务小区 (测量基站)的路损值需要小于一定阈值， 也 就是 UE接收到的服务基站 (测量基站)下的小区的 RSRP需要大于设定的阈值。 具体选择方法如下：
1、 MUE 到服务基站 (测量基站)的 PL^ 务基站 (测量基站）的发射功率 (MUE读取 SIB2)-RSRP(MUE 测量的服务基站 (测量基站)的参考符号功率强 度)；
2、 根据 MUE对于服务基站 (测量基站)的 PL来评估 MUE到服务基站 (测 量基站)的距离。 服务基站 (测量基站)可以设定一个 PL的阈值或者 RSRP的阈 值 (测量基站收到测量结果后， 自己计算 PL值)， 并且下发该阈值 (PL 阈值或 RSRP阈值)作为测量控制给 MUE。
3、 当 MUE发现满足设定的 PL值或 RSRP值时， MUE上^艮测量结果给 服务基站 (测量基站)； 上报的事件考虑：
PL: 本服务基站 (测量基站)下的小区的 PL小于设定的阈值；
RSRP: 本服务基站 (测量基站)下的小区的 RSRP大于设定的门限值，该事 件可以重用 A1事件： Serving becomes better than threshold, 因为用途不同， 需 要重新设置阈值。
4、 服务基站 (测量基站)根据 MUE上报的结果选择 PL最小的几个 MUE 作为干扰评估测量的 UE。
测量基站 eNB2设置选择的 UEs进行干扰基站的测量：
因为测量的目标是干扰检测， 而不是进行切换目标小区的选择， 也就是 UE不需要调频到目标小区的频率， 而是停留在被干扰小区的接收频带范围内 去检测在该范围内的相邻干扰小区的信号质量。所以测量基站 eNB2对于其选 择的 UE的测量控制和正常的 UE的测量控制相同， 所不同的是：
测量目标： 被测量小区频点和带宽， 被测量小区的标识（Identity, id ) , 被测量小区的上下行的配置， 被测量小区的偏置量， 被测量小区的 MBSFN配 置或空白帧配置，被测量小区的天线配置等， 这些信息可以通过目前已有的接 口 （比如： 长期演进（ Long Term Evolution, LTE ) 中的 X2口， 或通用移动 通信*** ( Universal Mobile Telecommunications System, UMTS ) 的 Iur口 , 或其他***的类似接口）获得。 但是对于干扰类的测量， 需要测量实体停留在 被干扰基站的工作频带范围内进行干扰小区的信号的测量。所以测量目标中的 被测量小区的中心频点可以设置为被干扰小区的中心频点，或者测量目标中的 被测量小区的中心频点位于被干扰小区的干扰频带范围内。此时， 测量目标中 的被测量小区的中心频点可以按照一定的类度（比如 LTE***而言， 可以按 照 6RB的类度进行 ) 自治的搜索。
当 LPN只有部分频带干扰测量基站时， 如前上述， 测量基站 eNB2可以 通过目前已经存在的接口获得 LPN的如下配置信息： 小区频点和带宽， 小区 的 id, 小区的上下行的配置， 小区的偏置量， 小区的 MBSFN配置或空白帧配 置， 小区的天线配置等。 测量基站可以根据 RAN4的性能规定， 获知 LPN的 哪部分频带对测量基站 eNB2有干扰。或者 eNB2在本基站上对 LPN的全频带 的 CRS进行测量， 然后分析那些频带的 CRS的干扰值比较大， 然后确定那部 分频带对该 eNB2有干扰。
对于部分频带干扰基站的测量和方案一的步骤三的方式一相同。
为了准确测量 LPN上的对测量基站 eNB2造成干扰的频带的 RSRQ值， 则需要对部分的 CRS符号而不是全部的 CRS符号进行测量。
为了通知部分 CRS的位置， 可以采用中心频率 +带宽的方式， 或者频率起 始分别指示的方法。 或者频率起 +offset的方式表达。
当被干扰频带或干扰频带为部分频带时，在此测量目标中指示需要测量的
CRS的范围。
选项一： CRS的中心频率 +测量的 CRS带宽的方法
MeasObjectEUTRA ::= SEQUENCE {
carrierFreq ARFCN-ValueEUTRA,
allowedMeasBandwidth AllowedMeasBandwidth,
presenceAntennaPort 1 PresenceAntennaPort 1 , measured— carrierFreq ARFCN-ValueEUTRA, (fc of CC or fc of CRS)
measured— bandwidth Measured— bandwidth or measured PRBs (bandwidth of partial carrier or CRS)
或者， 选项二： 测量的 CRS的起始位置和终止位置
MeasObjectEUTRA ::= SEQUENCE {
carrierFreq ARFCN-ValueEUTRA,
allowedMeasBandwidth AllowedMeasBandwidth,
presenceAntennaPort 1 PresenceAntennaPort 1 ,
measured— carrierFreq_start ARFCN-ValueEUTRA, measured— carrierFreq_stop ARFCN-ValueEUTRA, 或者， 选项三： 测量的 CRS的起始位置 +offset
MeasObjectEUTRA ::= SEQUENCE {
carrierFreq ARFCN-ValueEUTRA,
allowedMeasBandwidth AllowedMeasBandwidth,
presenceAntennaPort 1 PresenceAntennaPort 1 ,
measured— carrierFreq_start ARFCN-ValueEUTRA, measured— carrierFreq_offset Measured— bandwidth or measured PRBs
在选项三中， 如果测量的 CRS的起始位置是低频， 则 offset值为正值， 如果测量的 CRS的测量位置为高频， 则 offset值为负值。
除了上述方法外， UE还可以基于设定的类度， 比如 6RB或 1.25MHz的 测量带宽，在服务小区的基站范围内从低频到高频或者从高频到低频进行设定 类度的同频或异频测量。
在这种情况下， 为了减小产生的异频测量， 而且因为即使基站值检测部分 的 CRS符号， eNB也可以不改变测量频点 fc的配置， 而只是修改 CRS频带 的频点， 保持测量为同频测量。 或者测量基站 eNB2将其接收频带范围内的测 量都视为同频测量。
或者 UE保持测量的 fc是服务小区的中心频点，检测服务小区全部频带范 围内的相邻小区的导频信号， 并对干扰信号质量超过阈值部分的干扰信号（比 如图 3B中的干扰频带区域的 CRS符号 ) 的测量结果进行 L3操作， 并进行据 此进行干扰的评估和上报。对于干扰信号质量低于阈值部分的干扰信号（比如 图 3B中的非干扰频带区域的 CRS符号 )不进行 L3过滤操作， 不作为干扰信 号进行评估和事件的上报。 具体测量流程如下：
1、 测量基站配置 MUE需要上报的 LPN的 RSRQ的阈值， 并把该阈值在 测量控制消息中下发给 MUE;
2、 当 MUE发现满足设定的 LPN的 RSRQ的阈值时 , MUE上报 LPN的 测量结果给被干扰的测量基站；
3、 测量基站根据和 MUE上报的被干扰基站的 PL值和测量的 LPN的测 量值 (RSRQ值)， 评估 MUE的位置。
4、 被干扰基站选择不同位置的 MUE的 LPN的测量结果进行平均， 得到 被干扰基站收到的 LPN的干扰结果。
进一步地， 本发明实施例还提供了干扰处理的方法， 当测量基站所检测的 测量参考符号的接收质量值高于设定的阈值时，测量基站启动与干扰基站间的 干扰处理流程。上述干扰处理流程包括： 上述测量基站根据上述测量的结果向 上述干扰基站发送干扰处理请求； 或者， 上述测量基站在被干扰的子帧上取消 数据资源的调度； 或者， 上述测量基站仅对在被干扰的子帧上测量的干扰低于 设定阈值的用户设备 UE进行数据资源的调度。
方案六： 测量基站和 LPN之间进行干扰协商来解决干扰问题； 流程如图 7所示： 701 :干扰检测（ Interference is detected ); 702:干扰处理请求（ Interference process request )； 703: 干扰过程响应 ( Interference process response )； 更具 体地： 当测量基站发现 LPN基站对其产生干扰时， 并且测量基站获知 LPN对其 干扰的时域和频域范围后， 基站通过和 LPN之间的进行干扰的协商来解决干 扰问题， 其具体的流程：
1、 当测量基站 (eNB2)检测到干扰后， 基站可以发送干扰处理请求信息到 LPN, 在该干扰请求信息中， 包含着：
1A: 需要降低的发射功率信息， 该信息可以是一个绝对的发射功率值， 也可以是相对的发射功率， 比如功率升高或者降低多少 dB。 或者只是升高或 者降低的指示。
1A-1 : 发射功率为绝对阈值的情况下， 可以包括具体的发射功率的指示， 其发射功率范围比如为特定的 dBM;
1A-2:发射功率为相对阈值的情况下，可以包括具体指示调整的发射功率 的指示， 比如为 -dB, 或者 +dB。 如果同时支持升功率和降功率的情况下， 负 的 dB可以表明为降低功率， 正的 dB可以表明为升高功率。 或者在干扰的情 况下，相邻基站只指示降低的功率值。相邻的基站可以基于前面的干扰检测来 决定降低几个 dB。
IB希望进行功率控制的资源的时域或频域的位置指示：
1B-1 : 对于同一种 RAT的情况下， 调整的频域的资源位置可以为： 频率， 带宽， 子载波， 信道， PRB等， 对于时域的位置可以用时隙， 子帧， 无线帧， 超帧， PRB, 或者其他已经定义的可以识别的资源组合等；
1B-2: 对于异 RAT的情况下， 其频域的资源位置可以为： 频率范围（频率 启动和频率结束， 或者中心频率 +带宽， 信道等)， 时域上表示为， 时间戳的起 始， 子帧， 无线帧， 超帧或者时隙等。
1C: 或者希望进行调整的其他参数的指示信息：
1C-1 : LPN工作的中心频率和 /或频带，如果 LPN功率的中心频率和 /或频 带可以进行调整， 并且调整之后的 LPN对测量基站没有干扰， 则可以考虑更 改 LPN的中心频率和 /或频带的调整；
1C-2: LPN的下行子帧偏置量的变化信息： 如果 LPN的特定的下行子帧 对于测量基站的干扰大， 则 LPN可以通过调整同步偏置量， 比如无线帧中的 第一个下行帧在无线帧中的偏置位置做调整。
1C-3: LPN的上下行配置的变化信息： 如果 LPN的特定的下行子帧对于 测量基站的干扰大， LPN可以调整上下行的配比。 以降低特定的下行子帧对 测量基站的干扰。
1C-4: 天线倾角的调整： 包括水平天线角或者垂直天线角的角度。 LPN 通过改变水平倾角或垂直倾角可以修改其覆盖区域的范围，这样也可以降低对 测量基站的干扰。
2: LPN收到 eNB2发送的干扰处理请求， LPN根据指示的调整信息进行 调整， 并反馈干扰处理相应信息， LPN可以通过 eNB配置更新消息或者其他 的信息来携带干扰处理相应消息， 在该相应信息中包括：
已经调整的 LPN的功率信息； 已经调整的其他参数的信息。
进一步地， 本发明实施例还提供了方案七， 干扰处理流程包括：
Figure imgf000034_0001
方案七： 基站进行内部资源调度调整。 当基站检测到干扰基站的干扰时， 对于干扰严重的下行子帧， 基站的调度可以采用两种方式：
第一种方式是：在干扰严重的子帧上，不进行任何 UE的数据资源的调度, 可以进行公共的控制资源的调度；
第二种方式是： 在干扰严重的子帧上， 仅调度部分 UE的数据资源， 该部 分 UE为位于测量基站中心的， 没有受到 LPN干扰的 UE, 或者受到 LPN干 4尤轻的 UE。
本发明实施例提供了基站直接干扰检测以及基站选择 UE进行干扰检测的 方法和***，并且在检测出干扰问题后，还提供了基站间干扰协调解决的方案。 本发明带来的有益效果为： 解决了复杂的网络条件下， 同频， 异频， 异***情 况下的下行发送对其相邻频带的上行接收的干扰检测和干扰处理，使得网络可 以灵活部署和共存。
