一种实现干扰信息上报的方法、 系统及 UE 技术领域
本发明涉及终端设备领域的多种无线电技术的共存技术， 尤其涉及一 种实现干扰信息上报的方法、 系统及 UE。 背景技术
随着无线电技术与智能终端设备的发展， 为了支持终端设备用户的不 同通信需求， 需要在同一终端设备（UE, User Equipment )内集成多种无线 电技术。 图 1 是现有技术中同时使用三种无线电技术的终端设备的结构示 意图， 如图 1所示， 在该终端设备中， 分别使用长期演进（LTE, Long Term Evolution )技术子模块 101 , 使用 IEEE Std 802.11规范规定的无线局域网 ( WLAN , Wireless Local Area Networks )技术子模块 102 , 即无线局域网 站点 （ WLAN-STA, Wireless Local Area Networks Station ), 使用 IEEE Std 802.15规范规定的蓝牙（Bluetooth )子模块 103; 101、 102、 103三个子模 块之间通过无线电技术之间的接口 （ inter-radio interface )相连， 例如 101 子模块与 102子模块之间通过 L101相连， 102子模块与 103子模块之间通 过 L102相连， 101子模块与 103子模块之间通过 L103相连， 或三个子模 块受控于一个公共的控制模块 104,终端设备的三个子模块分别和各自无线 电技术所对应的对端设备进行无线通信，其中 101与演进型基站（LTE eNB, E-UTRAN NodeB ) 105通过空中接口进行无线通信， 102与另一个 WLAN STA106通过空中接口进行无线通信， 103与另一个 Bluetoothl07通过空中 接口进行无线通信。
在同一终端设备内设计多种无线电技术子模块时， 鉴于终端设备的体 积有限， 势必意味着同时设计有两种或两种以上的无线电技术子模块的终 端设备内， 两种或两种以上无线电技术子模块之间的空间距离很小， 例如 只有几个厘米甚至几个毫米， 而且该两种或两种以上无线电技术所对应的 天线端口之间的空间隔离度无法设计的足够大， 导致当同一终端设备内的 各个无线电技术子模块工作于相邻的频带时， 由于带外泄露（Out of band emission ), 杂散发射（Spurious emissions ), 接收机阻塞（Blocking )等原 因， 当其中一个无线电技术子模块发射信号时， 将干扰另一个无线电技术 子模块的信号接收， 反之亦然， 而且现有技术中的滤波器技术无法消除这 种邻频干扰， 从而影响各无线电技术子模块的通信质量， 本领域中称这种 邻频干扰现象为 "设备内共存干扰 " （ ICO , In-device Coexistence Interference λ
如图 1所示的终端设备， WLAN-STA和 Bluetooth工作于 "工业、 科学 及医疗 （ISM, Industrial Scientific and Medical )" 频带， 频段为 2.4GHz 〜 2.5GHz, 其中 WLAN信道（ WLAN Channel )使用 ISM频带中的 2.4GHz〜 2.4835GHz频段， Bluetooth信道（Bluetooth Channel )使用 ISM频带中的 2.4GHz ~ 2.497GHz频段； LTE的时分双工 （TDD, Time Division Duplex ) 模式工作于频带 40( Band 40 )和频带 38( Band 38 ), Band 40的频段为 2.3GHz 〜 2.4GHz, Band 38的频段为 2.57GHz〜 2.62GHz, 频分双工模式（ FDD, Frequency Division Duplex ) 的上行传输 ( Uplink Transmission ), 即 UE向 eNB传输工作于频带 7 ( Band 7 ), 频段为 2.5GHz〜 2.57GHz, FDD模式的 下行传输（ Downlink Transmission ), 即 eNB向 UE传输工作于 Band 7的 2.62GHz 〜 2.69GHz频段。 图 2是现有技术中 ISM频带和 LTE频带的分布 示意图，如图 2所示， ISM频带正好与 LTE TDD模式的 Band 40、 LTE FDD 模式 Band 7的上行传输频段相邻， 因此如果 101子模块使用 TDD模式且 使用 Band 40, 那么 101子模块与 102子模块、 103子模块之间将会相互干 扰， 如果 101子模块使用 FDD模式且使用 Band 7, 由于 LTE Band 7的上 行频带与 ISM频带毗邻， 因此 101子模块的上行发射将干扰 102子模块或 103子模块的下行接收。
设备内共存干扰会影响终端设备用户的通信质量， 降低用户的通信体 验， 为了抑制这种设备内共存干扰对各种无线电技术的通信质量的影响， 网络侧可以采用频分复用的方法， 即改变 LTE子模块的工作频率， 或改变 其他无线电子模块的工作频率， 使得 LTE子模块的工作频率与其他无线电 子模块的工作频率之间的频率间隔足够大； 或网络侧可以采用时分复用的 方法， 即控制 LTE子模块和其他无线电子模块的传输时间， 使 LTE子模块 和其他无线电子模块在不同的时间段上进行信号传输； 或对于近 LTE子模 块的上行发射干扰其他无线电子模块的下行接收的情况，网络侧可以对 LTE 子模块的上行发射进行功率控制， 控制 LTE子模块的上行发射功率在一定 的限制范围。 无论采取上述哪种方案解决设备内共存干扰， 现有技术中网 络侧均无从获取设备内共存干扰信息， 从而无从解决设备内共存干扰带来 的负面影响。 发明内容

下面通过附图及具体实施例对本发明再做进一步的详细说明。
本发明提供一种实现干扰信息上报的方法， 图 3是本发明实现信息上 报的方法的第一实施例的流程示意图， 如图 3所示， 该方法包括以下步驟： 步驟 301 , 当 UE检测到设备内共存干扰的干扰状态发生变化时， 将第 一种无线电技术的频率信息或第一种无线电技术的频率信息和附加干扰信 息上报给网络侧；
具体的， 设备内共存干扰的干扰状态发生变化包括： UE由不存在设备 内共存干扰的状态变为存在设备内共存干扰的状态，以及 UE由内存在设备 内共存干扰且已执行抑制干扰的措施的状态， 变为不再存在设备内共存干 扰的状态； UE判断设备内共存干扰的干扰状态发生变化的方法是： 终端设 备 UE根据各启用的共存于 UE内的无线电技术子模块的状态判断设备内共 存干扰的状态，该各启用的共存于 UE内的无线电技术子模块的状态是指各 共存于 UE内的无线电技术子模块的启用 /关闭状态；
当 UE内的第一种无线电技术与其他无线电技术同时处于开启状态，且 各无线电技术各自的工作频率足够近， 以至于将会导致设备内共存干扰， 则 UE确定检测到设备内共存干扰的干扰状态发生变化，或当 UE内已经存 无线电技术关闭， 则 UE确定设备内共存干扰的干扰状态发生变化； 当 UE检测到设备内共存干扰的干扰状态发生变化时，将第一种无线电 技术的频率信息或第一种无线电技术的频率信息和附加干扰信息上报给网 络侧； 其中， 该频率信息是指未干扰的频率信息和干扰的频率信息中的至 少一个； 未干扰的频率信息是指第一种无线电技术与其他无线电技术同时 电技术的未干扰的工作频率或未干扰的工作频率范围， 干扰的频率信息是 指第一种无线电技术与其他无线电技术同时工作时， 会与启用的其他无线 电技术产生设备内共存干扰的第一种无线电技术的干扰的工作频率或干扰 的工作频率范围； 这里，如果步驟 301中 UE确定设备内共存干扰不再存在 时， UE向网络侧上报的第一种无线电技术的频率信息为空；
所述将第一种无线电技术的频率信息上报给网络侧为： UE利用上报频 率范围的下限频率和 /或上限频率的方法， 或利用频带的索引号的方法上报 干扰的频率范围的方法， 将第一种无线电技术的频率信息上报给网络侧； 其中， 下限频率是指干扰的频率范围的区间的左端值， 上限频率是指干扰 的频率范围的区间的右端值；

表 4
根据表 1〜表 4可知， UE根据其他无线电技术的开启情况以及使用的中 心频率等参数， 可以估算出 LTE技术的干扰的频率范围；
例如， 当前 BT技术对 LTE技术产生了干扰， BT技术使用的频带的中 心频率位于 [ 2420, 2440 ]之内， 则 LTE技术的干扰的频率范围是 [ 2375, 2390 ], 基于该频带范围， 本实施例中， 当 UE确定存在设备内共存干扰的 干扰状态发生变化时， UE可以利用以下两种方法将第一种无线电技术的频 率信息上报给网络侧：
方法一、 上报频率范围的下限频率 Flow和 /或上限频率 Fhigh;
具体的，上报频率范围的下限频率 Flow和 /或上限频率 Fhigh的方法可 以通过上报具体数值的方式或 EARFCN的方式； 其中下限频率 Flow是指 LTE技术的干扰的频率范围的区间的左端值， 上限频率 Fhigh是指 LTE技 术的干扰的频率范围的区间的右端值， EARFCN是 0~65535之间的整数， 用于表示所有 E-UTRA的载波频率； 当 UE和网络侧已经预先约定频率间 隔时， 这里只需要上报上限频率或下限频率中的一个；
这里，采用具体数值的方式进行频率范围的下限频率 Flow和 /或上限频 率 Fhigh的上报， UE可以将具体的下限频率 Flow值 2375和 /或具体的上限 频率 Fhigh值 2390上报给网络侧； 或，
采用 EARFCN 的方式进行频率范围的下限频率 Flow和 /或上限频率 Fhigh的上报， LTE技术中 EARFCN的方式的使用方法是， E-UTRA信道 号列表如图 5所示：
Figure imgf000014_0001
表 5 表 5中 E-UTRA操作频带号即是 LTE技术工作的中心频率所在的具体 频带号， 表 5中 NDL与 NUL即分别是下行和上行的 EARFCN, 根据表 5 可以得到载波频率与 EARFCN的对应关系， 具体计算公式为：
FDL = FDL low + 0.1 (NDL - NOffs— DL) ( 1 )
FUL = FUL low + 0.1 (NUL - NOffs— UL) ( 2 )
其中， 公式（ 1 )给出了下行载波频率与下行 EARFCN 的对应关系， 公式（2 )给出了上行载波频率与上行 EARFCN的对应关系；
本实施例中， 干扰的频率范围位于 Band 40, 如表 5最后一行所示， 此 时 BT技术干扰 LTE技术的接收，因此查询表 5中下行中 Band 40对应的数 据，根据公式（ 1 )可以计算出上报频率范围的下限频率 Flow的值是 39400, 上报频率范围的上限频率 Fhigh的值是 39550;
利用上报频率范围的下限频率 Flow和 /或上限频率 Fhigh的方法，将第 一种无线电技术的频率信息上报给网络侧的优点是上报的频率范围可以动 态的变化， 因此频率范围比较灵活， 并且可以充分的利用现有协议实现， 具有较高的可行性；
方法二、 利用频带的索引号上报频率范围；
具体的， 所述频带的索引号上报频率范围的方法为： 根据协议预定义 的， 或 UE 和网络侧对可能与其他无线电技术产生干扰的所有频带进行划 分， 并对频带编号， 最后制成频带列表， 并通知对端， 用于保证 UE与网络 侧保存相同的频带列表； 所述编号即是索引号， 通过索引号可以查找到对 应的具体的频率范围； 例如， 根据表 1〜表 4所示， 所述索引号可以是表 1~ 表 4 中的序号栏中的数字； 不同的频带范围对应的索引号是网络侧与 UE 预先协商好的， UE在上报第一种无线电技术的频率信息时， 只需将索引号 告知网络侧即可； 通过合理设置序号范围， 网络侧还可以通过序号知道具 体是产生干扰的无线电技术以及具体的干扰方向； 例如， UE向网络侧上报 索引号 14, 则网络侧根据频带列表可以确定， 当前是 BT技术的发送干扰 了 LTE技术的接收；
采用利用频带的索引号上报频率范围的方法， 将第一种无线电技术的 频率信息上报给网络侧的优点是， UE上报给网络侧的信息载荷小、效率高， 即利用较少的信息比特传达较多的信息；
或， 在上报第一种无线电技术的频率信息时， UE还可以同时上报当前 可用的附加干扰信息， 该附加信息是指网络侧做出决策需要的除了频率信 息以外的其他信息， 包括各无线电技术采用时分复用 （TDM ) 方式工作时 的 TDM信息， 和 /或当前可用的测量结果， 和 /或第一种无线电技术的上行 传输干扰其他无线电技术接收的指示；
其中， UE上报给网络侧的附加干扰信息是 TDM信息时， 该 TDM信 息是： 时分复用传输时的通知信息， 和 /或 UE内与 LTE技术共存的其他无 线电技术的技术类型和业务类型， 例如， 如果其他无线电技术是 Bluetooh 技术， 则 Bluetooth技术的当前的业务类型为网络电话（VoIP, Voice over Internet Protocol )的语音应用 , 和 /或 LTE技术的传输时间长度信息及 TDM 的周期信息， 例如， 周期为 50ms, LTE技术的传输时间长度为 20ms, 和 / 或 TDM的周期信息和在 TDM周期内 LTE传输时间长度与非 LTE传输时 间长度的比例信息； 例如， 一个 TDM周期等于 LTE传输时间长度 +非 LTE 传输时间长度； 和 /或 UE根据协议规定查询 TDM信息表所得的索引信息， 一种协议规定的 TDM信息表如表 6所示， UE根据实际的共存无线电技术 及当前的业务类型查表， 向网络侧上报的 TDM信息表 6中的索引信息：
Figure imgf000016_0001

对于 LTE技术的传输时间长度信息及 TDM的周期信息，以及 TDM的 周期信息和在 TDM周期内 LTE传输时间长度与非 LTE传输时间长度的比 例信息， 这里需要说明的是， 这些 TDM信息是 UE向网络侧建议的 TDM 信息， 最终 LTE技术与其他无线电技术之间的 TDM关系， 即 LTE技术的 传输时间长度与非 LTE技术的传输时间长度的时序关系， UE建议的 TDM 信息供网络侧在做出决策时进行参考， 网络侧还需要根据自身的策略最终 做出决策；
UE上报给网络侧的附加干扰信息是当前可用的测量结果时， 该当前可 用的测量结果是指当前所有已经配置的测量任务上已经测量到的测量结 果；
UE 上报给网络侧的附加干扰信息是第一种无线电技术的上行传输干 扰其他无线电技术接收的指示时， 该指示是指当前干扰的具体情况为 UE 的第一种无线电技术的发送对其他无线电技术的接收造成干扰； 例如， 当 前 UE确定存在设备内共存干扰时， 在上报第一种无线电技术的频率信息 时， UE还可以通过同时向网络侧上报附加干扰信息的方法， 建议网络侧给 予自身需要的决策， 该决策用于作为 UE的干扰抑制措施， 如果 UE希望网 络侧给予采用 TDM方式的决策， UE将 TDM信息作为附加干扰信息， 与 第一种无线电技术的频率信息一起上报给网络侧；
或， UE也可以将当前可用的附加干扰信息全部发送给网络侧， 等待网 络侧^ 出的决策。
步驟 302,网络侧根据上报的频率信息或频率信息和附加干扰信息做出 决策； 具体的， 网络侧根据 UE上报的第一种无线电技术的频率信息，或第一 种无线电技术的频率信息和附加干扰信息，做出决策，并将决策发送给 UE;
如果 UE向网络侧上报第一种无线电技术的频率信息，网络可以做出下 列决策中至少一种决策： （ 1 )将1¾切换到不会产生设备内共存干扰的同覆 盖小区； （2 )如果 UE正在进行载波聚合， 则删除或去激活一个或多个存在 设备内共存干扰的辅服务小区 （Scell, Secondary Cell ), 和 /或， 增加或激 活其他不存在设备内共存干扰且可以与主服务小区 （Pcell, Primary Cell ) 进行载波聚合的且与删除或去激活的 Scell同覆盖的 Scell; ( 3 )若 UE上报 的第一种无线电技术的频率信息为空，表示 UE内部不再存在设备内共存干 扰， 网络侧撤销之前做出的干扰抑制措施；
如果 UE向网络侧上报第一种无线电技术的频率信息和附加干扰信息， 网络侧可以做出上述三种决策以及下列对应不同附加干扰信息的决策中至 少一种决策： （1 )如果附加干扰信息包含 TDM信息， 网络侧为 UE内各启 用的无线电技术配置 TDM的工作模式； （ 2 )如果附加干扰信息是当前可用 的的测量结果（例如邻区的测量结果）， 网络侧将 UE切换到不会产生设备 内共存干扰的邻区； 或如果 UE正在进行载波聚合， 网络侧可以删除或去激 活一个或多个存在设备内共存干扰的 Scell, 和 /或增加或激活其他不存在设 备内共存干扰且可以与 Pcell进行载波聚合的且与删除或去激活的 Scell不 同覆盖的 Scell; ( 3 )如果附加干扰信息是第一种无线电技术的上行传输干 扰其他无线电技术接收的指示，网络侧降低或限制 UE内第一种无线电技术 的上行传输功率；
这里需要说明的是，当 UE向网络侧上报的第一种无线电技术的频率信 息为空时， 网络侧将做出撤销之前的干扰抑制措施的决策。
步驟 303， 网络侧将决策发送给 UE;
具体的， 网络侧将做出的决策发送给 UE, UE收到该决策后， 执行该 决策。
图 4是本发明实现干扰信息上报的方法的第二实施例的流程示意图， 如图 4所示， 该方法包括以下步驟：
步驟 401 , 当 UE检测到设备内共存干扰的干扰状态发生变化时， 将第 一种无线电技术的频率信息上报给网络侧；
具体的， 参见步驟 301。
步驟 402, 网络侧根据 UE上报的频率信息判断是否能够做出决策， 如 果否， 执行步驟 403 , 如果是， 执行步驟 405;
具体的， 网络侧收到 UE上报的第一种无线电技术的频率信息后，根据 该频率信息判断是否能够做出决策， 如果能够做出决策， 执行步驟 405, 如 果根据频率信息还不能够做出决策， 执行步驟 403; 网络侧可以做出一共 7 种决策， 其中， 决策 1、 决策 2和决策 3是网络侧根据 UE上报的频率信息 能够做出的决策， 决策 4〜决策 7是网络侧根据 UE上报的频率信息不能够 做出的决策， 7种决策具体如下：
1 : 能够做出决策， 将 UE切换到不会产生设备内共存干扰的同覆盖小 区；
具体的， 当网络侧根据 UE上报的设备内共存干扰相关的频带信息， 网 络侧自身的资源使用情况， 以及运营商的运营策略， 确定网络中存在与 UE 当前的服务小区的覆盖范围相同的同覆盖小区， 且该同覆盖小区使用未干 扰 LTE频率时， 网络侧可以做出干扰抑制决策， 该干扰抑制决策是将 UE 切换到所述同覆盖小区，即是将 UE切换到不会产生设备内共存干扰的同覆 盖小区， 此时， 网络侧根据 UE上报的第一种无线电技术的频率信息， 能够 做出决策， 执行步驟 405;
2: 能够做出决策， 删除或去激活一个或多个存在设备内共存干扰的 Scell,和 /或增加或激活其他不存在设备内共存干扰且可以与 Pcell进行载波 聚合的且与删除或去激活的 Scell同覆盖的 Scell;
具体的， 如果 UE当前的工作状态是正在进行载波聚合， 即 UE同时工 作在一个 Pcell和一个或 Scell上，网络侧根据 UE上报的设备内共存干扰相 关的频带信息，确定 Pcell不存在设备内共存干扰 ,仅其中的一个或多个 Scell 存在设备内共存干扰时， 网络侧可以做出干扰抑制决策， 该干扰抑制决策 是删除或去激活该一个或多个存在设备内共存干扰的 Scell;
进一步的， 网络侧根据载波聚合的部署情况， 确定与被删除或去激活 的所述 Scell具有相同覆盖范围的同覆盖小区的覆盖范围内， 有其他不存在 设备内共存干扰且可以与 Pcell进行载波聚合的小区时， 网络侧还可以在做 出删除或去激活该一个或多个存在设备内共存干扰的 Scell的干扰抑制决策 的同时， 增加或激活其他不存在设备内共存干扰且可以与 Pcell进行载波聚 合的小区； 此时， 网络侧根据 UE上报的第一种无线电技术的频率信息， 能 够做出决策， 执行步驟 405;
3: 能够做出决策， 撤销或停止 UE正在执行的干扰抑制措施； 具体的，如果 UE上报的第一种无线电技术的频率信息为空，说明当前 UE内部不再存在设备内共存干扰， 网络侧可以 ·ί敦销或停止 UE正在执行的 干扰抑制措施；
4: 需要降低或抑制 UE内第一种无线电技术的上行传输功率， 目前不 能够故出决策；
具体的， 与网络侧进行交互的无线电技术是干扰方子模块， 通过降低 或抑制 UE 内干扰方子模块的上行传输功率可以抑制设备内共存干扰； 例 如， 当前与网络侧交互的无线电技术是第一种无线电技术， 干扰方子模块 是第一种无线电技术， 例如 LTE技术， 若 LTE技术使用 FDD的工作模式， 并工作于 Band 7, 且正在进行上行传输功率， 那么会对设备内启用的使用 ISM频带的其他无线电技术的接收产生干扰， 这时， 网络侧可以做出上行 传输功率控制的干扰抑制决策， 以降低 UE的 LTE技术的上行传输功率， 从而降低 LTE技术对设备内其他无线电技术的干扰； 但是， 仅根据 UE上 报的第一种无线电技术的频率信息， 网络侧不能够做出决策， 网络侧还需 要知道 UE的干扰方向， 因此 UE还需要上报附加干扰信息给网络侧， 执行 步驟 403;
5: 需要将 UE切换到不会产生设备内共存干扰的邻区， 目前不能够做 出决策；
具体的， 当网络侧根据 UE上报的第一种无线电技术的频率信息， 网络 的资源使用情况以及运营商的运营策略，确定如果将 UE切换到邻区，则不 会与设备内的其他无线电技术产生干扰； 但是， 如果要将 UE切换到邻区， 网络侧还需要知道关于 UE当前服务小区的邻区的测量结果，该测量结果可 以是邻区的参考信号接收质量（ RSRQ , Reference Signal Received Quality ) 和 /或参考信号接收功率（ RSRP, Reference Signal Receiving Power )等参量； 此时，根据 UE上报的第一种无线电技术的频率信息， 网络侧不能够做出决 策， 网络侧还需要知道 UE当前服务小区的邻区的测量结果， 因此 UE还需 要上报附加干扰信息， 执行步驟 403;
6: 需要删除或去激活一个或多个存在设备内共存干扰的 Scell, 和 /或 增加或激活一个或多个不存在设备内共存干扰且可以与 Pcell进行载波聚合 且与删除或去激活的 Scell非同覆盖的 Scell,目前不能够做出干扰抑制决策； 具体的， 如果 UE当前的工作状态是正在进行载波聚合， 即 UE同时工 作在一个 Pcell和一个或多个 Scell上，网络侧根据 UE上报的设备内共存干 扰相关的频带信息， 确定 Pcell不存在设备内共存干扰， 仅其中的一个或多 个 Scell存在设备内共存干扰时， 网络侧可以做出决策， 该决策是删除或去 激活该一个或多个存在共存干扰的 Scell;
但是， 进一步的， 网络侧根据载波聚合的部署情况， 确定与被删除或 去激活的所述 Scell的邻小区不会与设备内其他无线电技术产生干扰， 且可 以与 Pcell进行载波聚合时， 网络侧还需要知道关于 UE当前服务小区的邻 区的测量结果， 才能够做出决策， 该测量结果可以是邻区的 RSRQ 和 /或 RSRP等参量； 因此， 此时网络侧根据 UE上报的第一种无线电技术的频率 信息， 不能够做出决策， 网络侧还需要知道 UE当前服务小区的邻区的测量 结果， 因此 UE需要上报附加干扰信息给网络侧， 执行步驟 403; 作模式， 目前不能够做出决策；
具体的，网络侧可以通过为 UE中启用的产生设备内共存干扰的各无线 电技术配置 TDM的工作模式的方法来抑制干扰， 例如， 在有些国家， 运营 商的频率资源特别少， 比如印度， 有时只有 Band40的高频段可用， 在这种 情况下， 利用为 UE 中启用的产生设备内共存干扰的各无线电子模块配置 TDM的工作模式的方案来抑制干扰是不可避免的； 此时， 根据 UE上报的 第一种无线电技术的频率信息， 网络侧不能够做出决策， 网络侧还需要知 道当前设备内使用的其他无线电技术的技术类型和使用的各种无线电技术 的业务类型， 以及可选的使用的各种无线电技术的估计通信时间等内容， 因此 UE需要上报附加干扰信息， 执行步驟 403。
步驟 403 , 网络侧指示 UE进行附加信息的上报；
具体的， 针对步驟 402中的决策 4〜决策 7, 网络侧通过发送附加干扰 信息上报指示给 UE, 来告知 UE将附加干扰信息上报给网络侧；
其中，对于决策 4, 网络侧可以通过发送干扰方向的附加干扰信息上报 指示的方式， 指示 UE进行附加干扰信息的上报， 此时， UE上报的附加干 扰信息的内容是 UE自身的干扰方向；
对于决策 5和决策 6, 网络侧可以为 UE配置测量的方式， 指示 UE进 行附加干扰信息的上报， 此时， UE上报的附加干扰信息的内容是 UE自身 当前服务小区的邻区的测量结果；
对于决策 7, 网络侧可以通过发送 TDM信息的附加干扰信息上报指示 的方式， 指示 UE进行附加干扰信息的上报， 此时， UE上报的附加干扰信 息的内容是 TDM信息；
当网络侧未告知 UE上报的附加干扰信息的内容时， UE将上述附加干 扰信息的内容都发送给网络侧。
步驟 404, 收到网络侧要求上报附加信息的指示后， UE将附加干扰信 息上报给网络侧；
具体的， UE收到网络侧发送的附加干扰信息上报指示后， 根据该附加 干扰信息上报指示， 确定网络侧需要的附加干扰信息， 将附加干扰信息上 报给网络侧。
步驟 405， 网络侧将决策发送给 UE;
具体的， 针对步驟 402中的决策 1和决策 2, 网络侧将根据 UE上报的 频率信息做出的决策发送给 UE, UE收到决策后， 执行该决策。
为实现上述方法， 本发明还提供一种实现干扰信息上报的系统， 图 5 是本发明实现干扰信息上报的系统的结构示意图， 如图 5 所示， 该系统包 括： UE51、 网络侧 52; 其中，
