在同一个 UE内设置多种无线电技术的模块时， 鉴于 UE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 UE内 ,该两种或两种以 上无线电技术的模块之间的空间距离相距很近， 比如几个厘米甚至几个毫 米， 也即该两种或两种以上无线电技术所使用的天线端口之间的空间隔离 度无法设计的足够大；从而容易导致当同一个 UE内的各无线电技术工作于 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模块 进行发射时， 将干扰另一个无线电技术模块的接收， 反之亦然。 而且， 现 有的滤波器技术无法消除这种邻频干扰， 从而会影响各无线电技术模块的 通信质量。上述干扰称之为设备内共存干扰（ ICO干扰， In-device Coexistence Interference )。
以图 1所示的 UE为例， WLAN和 Bluetooth工作于工业、 科学及医疗 ( ISM, Industrial Scientific and Medical )频带 （ 2.4GHz~2.5GHz；), 其中， WLAN信道使用 ISM频带中的 2.4GHz~2.4835GHz频段， Bluetooth信道使 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: 2.3GHz~2.4GHz )和频带 38 ( Band 38: 2.57GHz~2.62GHz ); 频分双工 （FDD, Frequency Division Duplex )模式的上行传输 ( Uplink Transmission ) 工作于频带 7 ( Band 7 ) 的 2.5GHz~2.57GHz频段， FDD模式的下行传输（ Downlink Transmission ) 工作于 Band 7的 2.62GHz~2.69GHz。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 模块 11使用 TDD模式且使用 Band40, 那么模块 11与模块 12、 模块 13之 间将相互干扰； 如果模块 11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， 模块 11的上行发射将干扰模块 12 或模块 13的下行接收。
在现有 LTE 系统中， UE通过参考信号接收质量 （RSRQ, Reference Signal Received Quality )的测量实现对来自设备外干扰的检测， 这种方式比 较适合于网络已知干扰源的场景。 网络一般可以根据网规、 网优支持下配 置合理的测量评估及测量上报参数，通过 UE上报的服务小区的信号质量测 量结果以及相邻小区的信号质量测量结果，判断 UE在服务小区是否受到干 扰，若判断受到干扰， 则基站可通过小区间干扰协调技术或通过将 UE切换 到相邻小区来保证 UE的通信质量。 现有 LTE系统 UE的测量过程中， 由 于来自设备外的干扰一般是一个由弱到强的过程，因此 UE上报给基站的测 量结果是对一段时间内（比如 320ms甚至更长时间）各测量进行平滑（ filter ) 处理后的结果， 以防止由于信号的短暂抖动导致 UE的乒乓切换。与这种来 自设备外的干扰不同， 设备内共存干扰具有突发性和强干扰性。
设备内共存干扰的存在会降低智能终端内不同无线电技术的通信质 量， 以图 3所示的应用为例， 智能 UE配置有使用 LTE技术的 LTE模块和 使用 WLAN技术的模块， 具备无线相容性认证（ WiFi, Wireless Fidelity ) 便携路由器（ WiFi portable router ) 的功能。 其中， LTE eNB通过空中接口 L301与 UE的 LTE模块通信， UE的 WLAN模块通过空中接口 L302与便 携式电脑（ Laptop )通信。 当 UE的 LTE模块工作频点为 2.390GHz, WLAN 模块在 2.401GHz~2.423GHz之间频带工作， UE的 LTE模块进行下行接收 而同时 WLAN模块正好对 Laptop发送数据时， LTE模块会受到 WLAN模 块的干扰。 而 WLAN模块对 Laptop所发送的数据是从 LTE模块的下行接 收获得的， 于是 WLAN设备的干扰导致 LTE模块下行数据接收效率低下， 反过来又影响了 WLAN模块向 Laptop发送数据的效率，最终影响用户体验。 反之亦然， 即 LTE模块的上行发送会干扰 WLAN模块的接收， 也同时会影 响 L301和 L302这两个通信链路， 最终影响用户体验。
由此可见， 多种不同的无线电技术共存于终端设备内时， 终端设备内 共存干扰会降低这多种不同的无线电技术的通信质量， 影响用户的通信体 发明内容

下面结合附图和具体实施例对本发明的技术方案进一步详细阐述。 本发明适用于内部有至少两种无线电技术共存的 UE, 为降低设备内共 存干扰， 提高 UE的通信质量， 以下所有实施方式中， 均以 LTE与 WLAN 或 Bluetooth共存于同一终端设备内时， LTE模块与对端网络的交互为例， 说明本发明实现终端内多种无线电技术共存的通信方法。 但并不构成对本 发明专利的不当限定， 比如本发明方法也同样适用于 LTE与其他无线电技 术共存时的通信， 以及通用移动通信系统 （ UMTS , Universal Mobile Telecommunications System )与其他无线电技术共存时的通信。 对应于 LTE 模块， 本发明专利中所述的网络侧是指 eNB; 对应于 UMTS模块， 所述网 络侧是指 NB ( NodeB )。 本发明中出现的 UE向网络侧上报， 是指 UE内部 与网络侧进行通信的无线模块向网络侧上报； 本发明中出现的网络侧向 UE 指示， 是指网络侧向 UE内部与网络侧进行通信的无线模块指示。
本发明所提供的一种终端内多种无线技术共存的通信方法， 如图 4所 示， 主要包括以下步驟：
步驟 401 , UE判断设备内共存干扰的状态， 并将设备内共存状态信息 上报给网络侧。
其中， UE判断设备内共存干扰的状态的方法有两种：
方案一、 UE自主判断。
具体的， UE根据各共存于 UE内的无线电模块的状态判断设备内共存 干扰的状态。 各共存于终端设备内的无线电模块的状态是指， 各共存于设 备内的无线电模块的启用 /关闭状态； 若处于启用状态， 还包括各处于启用 状态的无线电模块的工作频率信息、 发射机技术指标、 接收机技术指标等 状态的一个或多个。 判断方法可以为：
若 UE内部原本不存在设备内共存干扰， 当前 UE根据各共存于 UE内 的无线电模块的状态可知： 终端设备内的各无线电模块同时处于启用状态， 且各模块工作于邻频状态，则 UE可以判断当前设备内共存干扰的状态为存 在设备内共存干扰；
若 UE内部原本存在设备内共存干扰， 当前 UE根据各共存于 UE内的 无线电模块的状态可知： 原本产生设备内共存干扰的无线电模块已经处于 关闭状态， 或者产生设备内共存干扰的某个无线电模块已经发生跳频， 因 此各启用的无线电模块不再处于邻频工作状态，则 UE可以判断当前设备内 共存干扰的状态为不再存在设备内共存干扰。
方案二、 UE根据网络侧配置的策略进行判断；
具体的， 所述网络侧配置的策略， 包括：
策略 1、 网络侧为 UE配置测量量为 RSRQ的 A1/2事件； 或者 策略 2、 网络侧为 UE配置一个判断设备内共存干扰的门限。
对应上述策略 1 , 若 UE内部原本不存在设备内共存干扰， 当 UE判断 所述 A2事件满足触发测量报告的条件时， UE可以判断当前设备内共存干 扰的状态为存在设备内共存干扰； 若 UE内部原本存在设备内共存干扰， 当 UE判断所述 A1事件满足触发测量报告的条件时， UE可以判断当前设备内 共存干扰的状态为不再存在设备内共存干扰。
对应上述策略 2, 若 UE内部原本不存在设备内共存干扰， 当 UE判断 服务小区的信号质量小于该门限，或者 UE根据各共存于 UE内的无线电模 块的状态判断干扰强度高于门限时， UE可以判断当前设备内共存干扰的状 态为存在设备内共存干扰； 若 UE内部原本存在设备内共存干扰， 当 UE判 断服务小区的信号质量大于该门限，或者 UE根据各共存于 UE内的无线电 模块的状态判断干扰强度低于门限时， UE可以判断当前设备内共存干扰的 状态为不再存在设备内共存干扰。
需要说明的是， UE可以单独使用上述两种方案进行判断或者采用上述 两种方案结合进行判断。
所述设备内共存干扰状态信息是指与网络侧通信的无线技术的干扰 /未 扰频率或频率范围信息； 或者与网络侧通信的无线技术的干扰 /未扰频率或 频率范围信息， 以及附加干扰信息。
进一步的， 所述与网络侧通信的无线技术的干扰频率或频率范围信息 是指， 当前与所述网络侧通信的无线技术， 会与设备内启用的其他无线技 术发生设备内共存干扰的频率或频率范围； 所述与网络侧通信的无线技术 的未干扰频率或频率范围信息是指， 当前与所述网络侧通信的无线技术，

围。
所述附加干扰信息包括以下至少之一：
当前可用的服务小区的测量结果和 /或邻区的测量结果；
各无线技术采用时分复用 （TDM, Time Division Multiplexing )方式工 作的 TDM信息；
设备内共存干扰的干扰方向。
其中， 所述 TDM信息可以是以下一种或几种：
UE需要进行时分复用工作模式的通知信息；
各启用的无线技术的时分复用信息， 所述无线技术的时分复用信息指 启用的无线技术的技术类型、 业务类型；
时分复用的周期信息；
UE查询时分复用信息表所得的索引信息。
步驟 402， UE执行网络侧指示的干扰抑制决策。
其中， 根据网络指示的不同的决策， UE可以执行以下策略中的一个或 多个策略：
1、 停止或取消之前的 （UE已经执行的）干扰抑制措施；
2、 切换到不会与 UE内的其他无线电技术产生干扰的小区；
3、 删除或去激活网络侧通知其删除或去激活在其中产生设备内共存干 扰的辅服务小区（ Scdl, Secondary Cell ), 并可以增加或激活网络侧通知其 增加或激活的不会产生设备内共存干扰的 Scell;
4、 进一步测量， 即 UE根据网络侧为其配置的进一步测量配置进行测 量， 根据测量内容上报并等待网络侧的进一步决策； 5、 为启用的产生设备内共存干扰的模块配置 TDM的工作模式。
6、 降低或限制设备内共存干扰的干扰方模块发射功率。
下面分别针对 UE判断设备内共存干扰的两种不同方案实现至少两种 无线电技术共存于终端设备内的通信方法进行详细阐述。
如图 5 所示， 是方案一实现至少两种无线电技术共存于终端设备内的 通信方法流程图， 主要包括以下步驟：
步驟 501 , UE自主判断设备内共存干扰的状态。
具体的， UE根据各共存于终端设备内的无线电模块的状态判断共存干 扰是否存在。 各共存于终端设备内的无线电模块的状态是指， 各共存于设 备内的无线电模块的启用 /关闭状态； 若处于启用状态， 还包括各处于启用 状态的无线电模块的工作频率信息、 发射机技术指标、 接收机技术指标等。 其中， 发射机技术指标包括： 带外泄露参数、 杂散发射参数、 邻道泄露参 数、 发射功率参数等； 接收机技术指标包括： 接收机阻塞参数、 接收机接 收功率灵敏度、 接收机带外阻塞参数等。
具体的， 以图 1所示的 UE为例， UE内部使用不同无线电技术的各个 模块之间可以通过接口相连， 例如 L101 与 L103, 或者所有无线电技术模 块都受控于一个公共的控制模块 14。 LTE模块 11可以通过上述两种方式中 的任意一种， 获知模块 12/模块 13的启用 /关闭状态。 进一步地， 若模块 12/ 模块 13处于开启状态， LTE模块 11可以通过接口 L101/L103或控制模块 14获知模块 12/模块 13的工作频率信息、 发射机技术指标、 接收机技术指 标， 并根据获取的工作频率信息、 发射机技术指标、 接收机技术指标， 判 断是否存在共存干扰， 或将可能出现共存干扰。 进一步的， UE还可以根据 获取的工作频率信息、 发射机技术指标、 接收机技术指标， 判断干扰 LTE 频率或未干扰 LTE频率信息； 其中， 所述干扰 LTE频率是指， 若 LTE模块 工作在对应频率上，则 LTE模块将被共存于设备内的其他无线电模块干扰， 和 /或若 LTE模块工作在对应频率上，则 LTE模块将干扰共存于设备的其他 无线电模块。 相对应的， 所述未干扰 LTE频率信息是指若 LTE模块工作在 对应频率上， 则 LTE模块和共存于设备内的其他无线电模块之间不会相互 干扰。
步驟 502, UE向网络侧上报设备内共存干扰状态信息。
所述设备内共存干扰状态信息是指与网络侧通信的无线技术的干扰 /未 扰频率或频率范围信息； 或者与网络侧通信的无线技术的干扰 /未扰频率或 频率范围信息， 以及附加干扰信息。
进一步的， 所述与网络侧通信的无线技术的干扰频率或频率范围信息 是指， 当前与所述网络侧通信的无线技术， 会与设备内启用的其他无线技 术发生设备内共存干扰的频率或频率范围； 所述与网络侧通信的无线技术 的未干扰频率或频率范围信息是指， 当前与所述网络侧通信的无线技术， 围。
若 UE判断的设备内共存干扰状态为当前或将要不存在设备内共存干 扰， 则用所述与网络侧通信的无线技术的干扰 /未扰频率或频率范围信息设 为空来表示。
所述附加干扰信息包含以下至少之一：
当前可用的服务小区的测量结果和 /或邻区的测量结果；
各无线技术采用 TDM方式工作的 TDM信息；
设备内共存干扰的干扰方向。
步驟 503 , 网络侧根据 UE上报的设备内共存干扰的状态信息， 确定决 策， 并将该决策通知给 UE。 根据 UE上报的设备内共存干扰的状态信息不 同， 网络侧给出的决策结果也不相同。
对应设备内共存干扰状态信息为与网络侧通信的无线技术的干扰 /未扰 频率或频率范围信息时， 若所述状态信息不为空， 则网络侧可以根据当前 资源以及运营商策略做出以下决策：
1、 将 UE切换到不会产生设备内共存干扰的同覆盖小区；
根据 UE上报的信息、 网络的资源使用情况以及运营商的运营策略， 网 络侧判断网络中有与 UE 当前的服务小区同覆盖的不会发生设备内共存干 扰的小区存在， 则网络侧可以做出将 UE切换到所述同覆盖小区的决策，通 知 UE切换到所述同覆盖小区。 相应的， UE执行切换， 切换到所述同覆盖 小区。
2、 删除或去激活在其中会产生设备内共存干扰的 Scell, 进一步的， 可 同覆盖的小区为 Scell;
根据 UE上报的信息、 UE当前的工作状态、 网络的资源使用情况以及 运营商的运营策略， 若 UE当前正进行载波聚合， 即 UE同时工作在一个主 服务小区 （Pcdl, Primary Cell )和一个或多个 Scell上， 根据 UE上报的干 扰 LTE频率信息 /未干扰 LTE频率信息，网络侧判断 Pcdl不存在共存干扰， 仅其中的一个或多个 Scell存在共存干扰，则网络侧可以做出删除 /去激活所 述一个或多个存在共存干扰的 Scell的决策。 进一步的， 若网络侧根据载波 聚合的部署情况和 /或根据 UE上报的邻区的测量结果， 判断存在其他不存 在共存干扰且可以与 Pcdl进行载波聚合的小区， 则网络侧还可以进一步的 在做出删除 /去激活决策的同时， 增加或激活所述其他不存在共存干扰且可 以与 Pcell进行载波聚合的小区。
3、 为 UE配置进一步测量， 或通知 UE进一步上报附加干扰信息； 网络侧根据 UE当前上报的信息无法做出决策时，可以为 UE配置进一 步测量， 期望 UE进一步上报网络需要的测量结果， 例如： 网络需要邻区的 测量结果， 则可以为 UE配置测量量为 RSRQ的 A3事件。 或者通知 UE进 一步上报附加干扰信息。 网络侧等待 UE的进一步信息上报，做出进一步的 决策。
对应设备内共存干扰的状态信息为与网络侧通信的无线技术的干扰 /未 扰频率或频率范围信息时，若所述状态信息代表 UE不再存在设备内共存干 扰， 可以采用将所述状态信息置为空的操作来达成， 则网络侧可以根据当 前资源以及运营商策略做出取消之前干扰抑制决策的决策。
对应设备内共存干扰的状态信息为与网络侧通信的无线技术的干扰 /未 扰频率或频率范围信息和附加干扰信息时，则网络侧可以根据 UE上报的附 加信息内容， 当前资源以及运营商策略^ 出以下决策：
1、 若 UE上报的附加干扰信息中包含邻区的测量结果， 则网络侧可以 做出将 UE切换到不会产生设备内共存干扰的同覆盖小区或者邻区的决策；
2、 若 UE上报的附加干扰信息中包含邻区的测量结果， 且当前该 UE 正在进行载波聚合， 网络侧可以做出删除或去激活在其中会产生设备内共 存干扰的 Scdl的决策， 进一步的， 可以做出增加或激活在其中不会产生设 备内共存干扰且与原删除或去激活的 Scdl 同覆盖小区或者邻小区为 Scdl 的决策；
3、 若 UE上报的附加干扰信息中包含所述 TDM信息， 网络侧可以做 出为 UE的各种启用的无线电技术配置时分复用的工作模式。
根据 UE上报的信息、 网络的资源使用情况、以及当前各种无线电技术 的传输需求情况， 网络侧判断网络中频谱资源比较紧张， 并没有其他频率 供 UE完成切换； 或者当前设备内共存干扰比较严重， 例如： BT (蓝牙， Bluetooth )技术正工作于 ISM频带的最低 20MHz, BT技术的发射将会干 扰整个 LTE技术 Band 40的接收。 网络侧此时根据 UE上报的各种无线电 技术的业务类型为 UE配置合理的时分复用机制。
4、 若 UE上报的附加干扰信息中包含干扰的方向信息， 网络侧可以做 出降低或限制 UE的干扰方模块的功率的决策。
根据 UE上报的信息， 若 UE上报的干扰信息中包含干扰 LTE频率信 息 /未干扰 LTE频率信息，当前发生 LTE技术在 Band 7上的发送对使用 ISM 频段的其他无线电技术的接收产生了干扰， 网络侧判断， 通过功率控制措 施可以将干扰降低到 UE可辨识标准， 所述可辨识标准， 即 UE可以正常解 码 BT技术或 WLAN技术接收的内容， 网络侧可以做出降低 UE中 LTE技 术发射功率的决策， 通过配置合适的功率控制方法， 降低设备内共存干扰。
步驟 504, UE根据网络侧的指示， 执行网络侧通知的决策。
如图 6所示， 是方案二实现至少两种无线电技术共存于终端设备内的 通信方法流程图， 主要包括以下步驟：
步驟 601 , UE根据网络侧配置的策略判断设备内共存干扰的状态。 在连接态下， UE必须测量服务小区的信号质量， 包括对参考信号接收 功率（ RSRP, Reference Signal Received Power )的测量和对 RSRQ的测量， 其中 RSRQ的测量结果可以反映 UE的受干扰情况； 此外， 为了及时获得 UE在服务小区的信号质量，网络可以为 UE配置针对服务小区的测量事件， 比如 A1/2事件， A1/2事件的触发上报测量报告的条件分别为服务小区的信 号质量大于门限和小于门限。
因此， 网络侧配置的策略具体的可以是利用 A1/2事件， 为 UE配置测 量量为 RSRQ的 A2事件。 若 UE内部原本不存在设备内共存干扰， 当 UE 判断所述 A2事件满足触发测量报告的条件时， UE可以判断当前设备内共 存干扰的状态为存在设备内共存干扰； 若 UE 内部原本存在设备内共存干 扰， 当 UE判断所述 A1事件满足触发测量报告的条件时， UE可以判断当 前设备内共存干扰的状态为不再存在设备内共存干扰。
网络侧配置的策略具体还可以是，网络侧为 UE配置一个判断共存干扰 的门限。 若 UE内部原本不存在设备内共存干扰， 当 UE判断服务小区的信 号质量小于该门限，或者 UE根据各共存于 UE内的无线电模块的状态判断 干扰强度高于门限时， UE可以判断当前设备内共存干扰的状态为存在设备 内共存干扰； 若 UE内部原本存在设备内共存干扰， 当 UE判断服务小区的 信号质量大于该门限，或者 UE根据各共存于 UE内的无线电模块的状态判 断干扰强度低于门限时， UE可以判断当前设备内共存干扰的状态为不再存 在设备内共存干扰。
后续步驟 602~604的操作分别与步驟 502~504的操作相同， 此处不再 赘述。
下面再结合具体实施例， 对本发明中实现两种无线电技术共存于设备 内时的通信方法进行详细说明。
如图 8所示， 是本发明实现至少两种无线电技术共存于终端设备内的 通信方法， 当 UE判断发生设备内共存干扰时，抑制设备内共存干扰的第一 具体实施例流程， 并以 LTE技术与网络侧 （eNB ) 的通信为例， 包括： 步驟 801 , UE检测判断存在设备内共存干扰。 UE通过自身的配置， 可以评估设备内共存干扰的发生， 评估方式由 UE的具体结构决定。 例如： UE可以获知各个无线电技术的启用 /关闭状态， 以及若处于启用状态，各自 的工作频率信息、 滤波器技术指标、 以及是否发生带外泄露、 杂散发射、 接收机阻塞等情况， 综合判断当前是否可能发生设备内共存干扰。 以图 1 所示 UE为例：
UE内部使用不同无线电技术的各个模块之间可以通过接口相连， 例如 L301 与 L103 , 或者所有无线电技术模块同时受控于一个公共的控制模块 14。 因此， LTE模块 11可以通过上述两种方式中的任意一种， 获知其他无 线电技术模块的启用 /关闭状态； 进一步地， 若其他无线电技术模块处于开 启状态， LTE模块 11可以通过接口获知其他无线电技术模块的工作频率信 息； 若 LTE模块 11与其他无线电技术模块同时工作于相邻频带， UE的滤 波器特性不理想，极有可能发生带外泄漏情况， 则 UE可以判断此时发生设 备内共存干扰。
若采用方案一与方案二的结合， 则同时执行则同时执行步驟 801-1 , 即 UE按照网络配置判断的操作。按照网络配置的策略，可以是测量量为 RSRQ 的 A2 事件， 即测量本小区的接收信号质量低于某一个门限时， 结合步驟 801中 UE的判断， 认定当前正在经历设备内共存干扰。 步驟 801的评估结果， UE将 LTE技术干扰 /未干扰的频率或频率范围信息 上报给网络侧， 可以设计一种新的信令供 UE上报 LTE技术干扰 /未干扰的 频率或频率范围信息。
步驟 803 , eNB向 UE发送进一步测量配置或通知 UE进行进一步上报 附加干扰信息。 网络侧根据 UE上报的频率信息， 为 UE配置合理的测量评 估和测量上报参数， 以供后续做出抑制设备内共存干扰的决策时所用， 同 时也为了进一步确认 UE确实正在经历设备内共存干扰。 这里有必要说明， 在步驟 801中， UE通过设备内各种无线电模块的启用 /关闭情况、各自使用 的频率信息和滤波器特性等条件判断是否经历设备内共存干扰， 由于带外 泄露、 杂散发射、 接收机阻塞等情况的发生具有不确定性， 因此这种评估 方式具有一定的判断错误概率。这里网络侧为 UE配置进一步测量可以确认 UE当前的确正在经历设备内共存干扰， 以便加强对干扰判断的可靠性， 也 可以获取进一步决策所需信息。
或者， 为了网络做出进一步决策， 网络可以要求进行进一步的上报附 加干扰信息。
为了加快干扰测量， 可以在测量配置中做出一定调整， 比如： 减小测 量配置中测量报告触发时间 （TTT, Time To Trigger ) 的配置、 修改测量配 置中时间触发门限等。 在步驟 802到 803的执行过程中， 使用 ISM频带的其他无线电技术模 块暂时停止工作， 这是为了保证设备内共存干扰指示上报以及测量配置信 息的下达不会因为 LTE技术受到设备内其他无线电技术的干扰而导致传输 失败。
以上所述的优势在于保证设备内共存干扰检测的可靠性，减少 UE需要 上 ·^艮的进一步测量 ·^艮告， 一方面可以减少 UE 的测量时延， 另一方面减少 UE测量结果上报的功率消耗。
步驟 804, UE根据网络侧配置的测量内容进行测量。
步驟 805 , UE上报测量报告（ MR )给网络侧。 例如， 网络侧为 UE配 置的测量与切换相关， 本步驟中上报的信息包括， 已配置的各个测量任务 中， 已经满足各自测量任务上报条件的、 保存在各自测量任务所对应的小 区触发列表（cell trigger list )中的各个邻区的测量结果， 或者所述列表中对 应的几个最强邻区的测量结果， 具体数目为网络侧为 UE配置的。
UE可以在上报的附加干扰信息中包含测量报告。
在步驟 803到 805的执行过程中， 为了避免使用 ISM频带的其他无线 电技术模块对测量或者信令的交互产生影响， 可以规定所述模块只在测量 间隙 （ Measurement Gap )期间可以工作。
步驟 806, 网络侧向 UE下达决策结果。 所述决策结果可以是如图 7所 示的几种解决 CQI干扰决策的一种或几种， 同时不限于该图示所给出的决 來。
若网络下达的决策为配置测量时， 按照如图 7所示的配置测量过程执 行， 不限定具体测量的次数， UE听从网络侧的决策结果进行执行。
步驟 807, UE执行网络决策。 UE根据步驟 806中网络侧给出的决策 结果相应的进行执行， 并且 UE会告知网络侧干扰抑制过程完成。
为了保证上述流程的正确执行， 优化所述流程， 避免异常情况， 这里 给出必要的保护流程：
步驟 808, 启动设备内共存干扰定时器。 为防止后续流程的信令交互过 程中出现突发性错误等情况， 导致后续流程无法进行， 网络侧在干扰抑制 流程中第一次向 UE发送信息时， 启动一个设备内共存干扰定时器，本流程 中即在步驟 803执行时启动所述设备内共存干扰定时器。
在设备内共存干扰定时器没有超时前， 网络侧收到步驟 807 中所述的 UE告知其完成干扰抑制过程的反馈， 网络侧停止所述设备内共存干扰定时 器， 本次干扰抑制过程完成； 若设备内共存干扰定时器超时， 网络没有收 到 UE的反馈， 本次干扰抑制过程失败， 执行步驟 809。
步驟 809, 采用其他干扰抑制流程或通知 UE重新开始本流程。 其他干 扰抑制流程可以是图 9、 图 10或图 11中的任意一种， 但并不限于所述几种 流程， 所有可行的干扰抑制流程都在上述可选范围内。 网络侧也可以通知 UE重新开始本流程， 即回到步驟 801。
这里根据不同的网络资源情况配置的设备内共存干扰定时器时长也不 相同， 便于网络侧灵活控制， 尽量减少干扰抑制过程的总时间。
需要说明的是， UE重新检测判断设备内共存干扰是有必要的， 由于设 备内共存干扰的突发性， 再次判断时， UE的 LTE模块与使用 ISM的其他 无线电技术模块可能已经不会产生相互干扰， 例如使用 ISM的其他无线电 技术模块已经关闭等； 或者， 再次检测时， 业务类型等情况已经改变， 这 都将导致 UE上报的干扰信息与前次不同。
上述过程的优点在于操作更加灵活，避免 UE执行无用测量， 降低测量 需要的时延， 并且每次传输的信息块长度较小， 出错的可能性也较小， 保 证了信息传输的可靠性。
如图 9所示，根据步驟 902中 UE测量的内容不同，是本发明实现方案 一的具体实施例流程， 或者是本发明实现方案一与方案二结合的实施例流 程。 当 UE判断发生设备内共存干扰时，抑制设备内共存干扰的第二具体实 施例流程， 并以 LTE技术与网络侧 （ eNB ) 的通信为例 , 包括：
步驟 901 , UE检测判断设备内共存干扰。 与步驟 801相同。
步驟 902, UE执行测量。
若采用方案一：网络侧与 UE在本步驟执行前已经对上报干扰信息做出 一定约定， 即网络侧需要的测量结果都已经在本步驟前下达给 UE, 可以包 括： 干扰方向， 即 LTE技术对其他使用 ISM频带的无线电技术通信质量的 干扰， 或者使用 ISM频带的无线电技术对 LTE技术的通信质量的干扰， 或 者两者都有； 服务小区测量结果； 邻小区测量结果； 各种无线电技术的业 务类型等内容。 即网络做出干扰抑制决策时需要的测量结果， 都可以通过 本步驟的测量中得到。
在本步驟之前， 网络针对需要进行的测量会为 UE做出预先配置，该配 置可以通过修改广播过程或者无线资源控制（ RRC, Radio Resource Control ) 连接建立过程、 RRC连接重建立、 RRC连接重配置等其他流程告知 UE, 配置信息包括若在 UE内部可能发生设备内共存干扰，则应该执行的具体测 量操作以及需要向网络侧上报的具体测量结果。
若采用方案一与方案二的结合： UE本步驟执行测量时， 首先按照网络 配置的策略，可以是测量量为 RSRQ的 A2事件， 即测量本小区的接收信号 质量低于某一个门限时，结合 901中 UE的判断，认定当前正在经历设备内 共存干扰； 其次，按照网络侧与 UE在本步驟执行前已经对上报干扰信息做 出一定约定， 即网络侧需要的测量结果都已经在本步驟前下达给 UE, 可以 包括： 干扰方向， 即 LTE技术对其他使用 ISM频带的无线电技术通信质量 的干扰， 或者使用 ISM频带的无线电技术对 LTE技术的通信质量的干扰， 或者两者都有； 服务小区测量结果； 邻小区测量结果； 各种无线电技术的 业务类型等内容。 即网络做出干扰抑制决策时需要的测量结果， 都可以通 过本步驟的测量中得到。
在本步驟之前， 网络针对需要进行的测量会为 UE做出预先配置，该配 置可以通过修改广播过程或者 RRC连接建立过程、 RRC连接重建立、 RRC 连接重配置等其他流程告知 UE, 配置信息包括若在 UE内部可能发生设备 内共存干扰， 则应该执行的具体测量操作以及需要向网络侧上报的具体测 量结果。
步驟 903, UE上报 LTE技术干扰 /未干扰频率或频率信息以及带有附加 信息的 MR。 UE根据步驟 901中评估出当前正在经历设备内共存干扰以及 步驟 902中的各种测量，进行设备内共存干扰指示以及带有附加信息的 MR 上报。 这里有必要说明， 本步驟中类似于将步驟 802和 805上报的内容合 并进行统一上报， 但不同于所述步驟的合并在于本步驟中上报的内容可能 比合并的内容更多。 因为预先配置的测量内容相比于实时配置的测量配置 的内容更多。
在步驟 901到 903的执行过程中， 为了避免使用 ISM频带的其他无线 电技术模块对测量或者信令的交互产生影响， 可以规定所述模块只在测量 间隙期间可以工作。
步驟 904, 网络侧向 UE发送决策结果。 网络^ 出的决策结果如图 7所 示， 注意本步驟中包括的决策结果不包括图 7所示的进一步测量， 是因为 网络侧已经提前为 UE配置了所有需要的测量。
在步驟 903到 904的执行过程中， 使用 ISM频带的其他无线电技术模 块暂时停止工作， 这是为了保证设备内共存干扰指示和测量结果上报， 网 络决策结果下达不会因为 LTE技术受到设备内其他无线电技术的干扰而导 致传输失败。
步驟 905, UE执行网络的决策。 与步驟 807相同。
为了保证上述流程的正确执行， 优化所述流程， 避免异常情况， 这里 给出必要的保护流程：
步驟 906, 启动设备内共存干扰定时器。 为防止后续流程的信令交互过 程中出现突发性错误等问题， 导致后续流程无法进行， 网络侧在干扰抑制 流程中第一次向 UE发送信息时， 启动一个设备内共存干扰定时器，本流程 中即在步驟 904执行时启动所述设备内共存干扰定时器。
在设备内共存干扰定时器没有超时前， 网络收到步驟 905中所述的 UE 告知其完成干扰抑制过程的反馈， 网络侧停止所述设备内共存干扰定时器， 本次干扰抑制过程完成； 若设备内共存干扰定时器超时， 网络没有收到 UE 的反馈， 本次干扰抑制过程失败， 执行步驟 907。
步驟 907, 采用其他干扰抑制流程或通知 UE重新开始本流程。 其他干 扰抑制流程可以是图 8、 图 10或图 11中的任意一种， 但并不限于所述几种 流程， 所有可行的干扰抑制流程都在上述可选范围内。 网络侧也可以通知 UE重新开始本流程， 即回到步驟 901。
这里根据不同的网络资源情况配置的设备内共存干扰定时器时长也不 相同， 便于网络侧灵活控制， 尽量减少干扰抑制过程的总时间。
上述过程的优点在于从步驟 901 (即 UE检测判断当前其正在经历设备 内共存干扰）到步驟 905 (即 UE执行网络的决策结果）， 信令交互次数较 少， 控制面时延较小。
如图 10和图 11所示， 是本发明实现方案二的具体实施例流程。 当 UE 判断发生设备内共存干扰时， 抑制设备内共存干扰的第三具体实施例流程， 并以 LTE技术与网络侧 （eNB ) 的通信为例， 图 10所示流程包括：
步驟 1001 , UE根据网络侧配置的策略判断设备内共存干扰。在本步驟 之前， 网络侧为 UE配置判断设备内共存干扰的具体策略， 所述网络侧配置 的策略， 可以包括：
1、 网络侧为 UE配置测量量为 RSRQ的 A2事件； 或者， 2、 网络侧为 UE配置一个判断共存干扰的门限。
其中， UE根据网络侧配置的策略判断， 进一步的， UE还可以根据网 络侧所配置策略的基础上结合 UE判断向网络上报干扰信息，对应上述网络 侧配置的策略， 具体包括：
对应上述策略 1 ,当 UE判断所述 A2事件满足触发测量报告的条件时， 向网络上报所述 A2事件触发的测量报告；
对应上述策略 2, 当 UE判断服务小区的信号质量小于该门限， 或者 UE根据各共存于终端设备内的无线电模块的状态判断干扰强度高于门限 时， UE向网络上报干扰信息。
步驟 1002, UE上报干扰信息。根据判断设备内共存干扰的具体网络策 略配置， UE执行具体的 MR上报操作。 若网络为 UE配置 A2事件作为判 断设备内共存干扰的具体策略，当 UE检测到服务小区信号强度低于设定门 限，等于或超过 TTT时间时， UE向网络上报所述 A2事件触发的测量报告。 这里只是举例说明， 本步驟不限于此例。
步驟 1003 , 网络侧向 UE发送进一步的测量配置。 在执行本步驟之前， 当网络侧收到 UE上报的 MR后， 认为 UE可能正在经历设备内共存干扰， 则为 UE配置进一步测量， 一方面确认 UE确实正在经历设备内共存干扰， 另一方面为了后续步驟中网络做出干扰抑制决策提供必要的信息。 例如， 若利用现有测量配置， 则网络可以为 UE配置测量的 A3事件（邻区信号强 度比服务小区高出设定的偏移量）或 A4事件（邻区信号强度高于设定的门 限）或 A5事件（服务小区信号强度低于门限 1且邻区信号强度高于门限 2 ) 或这三种事件的任意组合。也可以为 UE配置其他新的测量事件， 用来触发 测量报告的上报。
在步驟 1002到步驟 1003的执行过程中， 使用 ISM频带的其他无线电 技术模块暂时停止工作， 这是为了保证 MR的上报和网络进一步测量配置 的下达不会因为 LTE技术受到设备内其他无线电技术的干扰而导致传输失 败。
步驟 1004, UE根据 1003的配置进行测量： 本步驟与 1001类似， 不同 处在于这里执行的测量的具体配置不是网络预先告知 UE的，而是网络侧在 1003步驟告知 UE的， 进行测量的内容也不同。
步驟 1005 , UE根据 1003的配置上报 MR: 本步驟与 1002类似， 不同 处在于这里执行的测量的具体配置不是网络预先告知 UE的，而是网络侧在 1003步驟告知 UE的， 上报的具体内容也不同。
在步驟 1003到 1005的执行过程中， 为了避免使用 ISM频带的其他无 线电技术模块对测量或者信令的交互产生影响， 可以规定所述模块只在测 量间隙期间可以工作。
步驟 1006, 网络侧向 UE发送决策结果。 与步驟 806的操作相同。 步驟 1007, UE执行网络的决策。 与步驟 807的操作相同。
为了保证上述流程的正确执行， 优化所述流程， 避免异常情况， 这里 给出必要的保护流程：
步驟 1008, 启动设备内共存干扰定时器。 为防止后续流程的信令交互 过程中出现突发性错误等情况， 导致后续流程无法进行， 网络侧在干扰抑 制流程中第一次向 UE发送信息时， 启动一个设备内共存干扰定时器，本流 程中即在步驟 1003执行时启动所述设备内共存干扰定时器。
在设备内共存干扰定时器没有超时前， 网络收到步驟 1007 中所述的 UE告知其完成干扰抑制过程的反馈， 网络侧停止所述设备内共存干扰定时 器， 本次干扰抑制过程完成； 若设备内共存干扰定时器超时， 网络没有收 到 UE的反馈， 本次干扰抑制过程失败， 执行步驟 1009。
步驟 1009, 采用其他干扰抑制流程或通知 UE重新开始本流程。 其他 干扰抑制流程可以是图 8、 图 9或图 11中的任意一种， 但并不限于所述几 种流程， 所有可行的干扰抑制流程都在上述可选范围内。 网络侧也可以通 知 UE重新开始本流程， 即回到步驟 1001。
这里根据不同的网络资源情况配置的设备内共存干扰定时器时长也不 相同， 便于网络侧灵活控制， 尽量减少干扰抑制过程的总时间。
本流程的优点在于对终端设备的复杂度要求较低，不需要 UE具有可以 有 LTE系统框架以及流程， 具有前向兼容的优势。
如图 11所示， 当 UE判断发生设备内共存干扰时， 抑制设备内共存干 扰的第四具体实施例流程， 并以 LTE技术与网络侧 （eNB ) 的通信为例， 图 11所示流程包括：
步驟 1101 , UE根据网络配置的策略判断干扰并执行必要测量。在本步 驟之前，网络侧为 UE配置判断设备内共存干扰的具体策略以及必要的测量 配置。所述必要的测量配置是指网络要求 UE执行某些测量以提供网络做出 干扰抑制措施决策时需要的测量结果； 所述网络配置的策略， 可以包括： 网络为 UE配置测量量为 RSRQ的 A2事件； 或者， 网络为 UE配置一个判 断共存干扰的门限。
步驟 1102, UE上报设备内共存干扰指示及带有额外信息的 MR。 UE 还可以根据网络所配置策略的基础上结合 UE判断向网络上报干扰信息，对 应上述网络配置的策略， 具体包括： 当 UE判断所述 A2事件满足触发测量 报告的条件时， 向网络上报所述 A2事件触发的测量报告； 当 UE判断服务 小区的信号质量小于该门限，或者 UE根据各共存于终端设备内的无线电模 块的状态判断干扰强度高于门限时， UE向网络上报干扰信息。 所述带有额 外信息的 MR包括干扰信息， 具体的干扰信息内容主要是步驟 1101中 UE 执行的具体测量结果，因此也与网络在本流程为 UE提供的具体测量配置有 关。 在步驟 1101到步驟 1102执行过程中， 为了避免使用 ISM频带的其他 无线电技术模块对测量或者信令的交互产生影响， 可以规定所述模块只在 测量间隙期间可以工作。
步驟 1103 , 网络侧向 UE发送决策结果。 操作与步驟 904相同。
在步驟 1102到 1103的执行过程中， 使用 ISM频带的其他无线电技术 模块暂时停止工作， 这是为了保证测量结果与干扰信息的上报和网络决策 的下达不会因为 LTE技术受到设备内其他无线电技术的干扰而导致传输失 败。
步驟 1104, UE执行网络决策。 操作与步驟 905相同。
为了保证上述流程的正确执行， 优化所述流程， 避免异常情况， 这里 给出保护流程：
步驟 1105, 启动设备内共存干扰定时器。 为防止后续流程的信令交互 过程中出现突发性错误等问题， 导致后续流程无法进行， 网络侧在干扰抑 制流程中第一次向 UE发送信息时， 启动一个设备内共存干扰定时器，本流 程中即在步驟 1103执行时启动所述设备内共存干扰定时器。
在设备内共存干扰定时器没有超时前， 网络收到步驟 1104 中所述的 UE告知其完成干扰抑制过程的反馈， 网络侧停止所述设备内共存干扰定时 器， 本次干扰抑制过程完成； 若设备内共存干扰定时器超时， 网络没有收 到 UE的反馈， 本次干扰抑制过程失败， 执行步驟 1106。
步驟 1106, 采用其他干扰抑制流程或通知 UE重新开始本流程。 其他 干扰抑制流程可以是图 8、 图 9或图 10中的任意一种， 但并不限于所述几 种流程， 所有可行的干扰抑制流程都在上述可选范围内。 网络侧也可以通 知 UE重新开始本流程， 即回到步驟 1101。
这里根据不同的网络资源情况配置的设备内共存干扰定时器时长也不 相同， 便于网络侧灵活控制， 尽量减少干扰抑制过程的总时间。 此外， 当 UE判断当前或将要不存在设备内共存干扰时， 向网络侧上报 设备内共存干扰状态信息， 网络侧判断是否给出响应， 以及若是则给出何 种响应。 图 12所示流程包括：
步驟 1201 , UE判断当前或将要不存在设备内共存干扰。 UE根据设备 内各无线技术的工作状态，也即开启 /关闭状态以及各无线技术的工作频率， 判断当前或将要不存在设备内共存干扰。
以图 1所示 UE设备为例， UE通过 L101或控制模块 14可知当前 LTE 技术与 WLAN技术的工作状态。 当发生设备内共存干扰时， 为 LTE技术的 发送干扰了 WLAN技术的接受， 但是目前通过 L101或控制模块 14可知： WLAN技术已经或即将关闭，或者 WLAN技术已经或将要跳频到其他不会 受到 LTE技术工作频率干扰的频率， 则 UE可以判断当前或将要不存在设 备内共存干扰。
步驟 1202, UE上报设备内共存干扰状态信息。所述设备内共存干扰状 态信息指示当前或将要不存在设备内共存干扰， 进一步的， 还可以包括以 下信息的至少一种：
UE的服务小区的测量结果和 /或邻区的测量结果；
设备内启用的各种无线技术的技术类型、 业务类型；
设备内共存干扰的干扰方向等。
步驟 1203, 网络侧判断是否给出响应。 网络侧根据 UE上报的设备内 共存干扰状态信息， 判断是否需要对 UE进行响应。 若是， 则执行 1204; 若否， 则流程结束。
若 UE上报当前或将要不存在设备内共存干扰，以及 UE的服务小区的 测量结果， 和邻区的测量结果。 网络侧判断， 若当前服务小区的质量优于 邻区质量， 则可以不做出响应； 若网络侧判断当前邻区的质量优于服务小 区的质量， 则可以对 UE故出响应。 步驟 1204, 网络侧向 UE发送响应策略。 网络侧在步驟 1203中判断需 要对 UE做出响应，根据 UE上报的设备内共存干扰状态信息确定做出何种 响应策略。 所述响应策略可以包括以下的一种或几种：
UE进一步执行测量；
将 UE切换到质量更好的邻小区；
增加或激活可以与 Pcdl进行载波聚合的 Scdl;
为 UE配置合适的 LTE技术传输周期；
增加 UE的 LTE技术模块功率。
步驟 1205 , UE执行收到的响应策略。 流程结束。
对应上述终端内多种无线技术共存的通信方法， 本发明还提供了一种 终端内多种无线技术共存的通信系统， 包括： UE和网络侧。 其中， UE用 于自主判断、 和 /或根据网络侧配置的策略判断设备内共存干扰的状态， 并 将设备内共存干扰状态信息上报给网络侧； 还用于执行网络侧指示决策。 网络侧， 用于根据 UE上报的设备内共存干扰状态信息， 向 UE指示所述决 來。
