Description

说明书 发明名称:一种降低 iSGLTE稱合灵敏度劣化的方法及移动终端
[0001] 本申请要求于 2018年 11月 21日提交中国专利局、 申请号为 201811389422.7、 发 明名称为“一种降低 SGLTE稱合灵敏度劣化的方法及移动终端”的中国专利申请 的优先权， 其全部内容通过引用结合在本申请中。
技术领域
[0002] 本申请涉及移动终端通信技术领域， 尤其涉及一种降低 SGLTE稱合灵敏度劣化 的方法及移动终端。
背景技术
[0003] 所谓灵敏度劣化 （de-sense） ， 就是移动终端在弱信号情况下， 外界或者本体 干扰源的引入导致音频质量下降或者数据误码率高， 甚至掉话或者掉线的现象 。 引起耦合灵敏度劣化的原因很多， 比如 camera、 SIM卡、 LCM、 TP等周边器 件干扰， 如双工器、 四工器的发射干扰接收等器件本身干扰， 或如 Band7&40和 WIFI&BT频谱资源邻近弓 I起的频谱资源干扰等。 周边器件干扰主要是 MIPI data 和 dock引起的， 等器件本身干扰主要是器件隔离度差引起的， 频谱资源干扰是 设备两种工作模式共存情况频谱资源的互干扰。
[0004] SGLTE作为新颖的手机工作模式呈现在消费者的面前， SGLTE要求手机在 GS
M和 LTE模式工作， 前者提供语音后者提供数据， 意味着可以同时通话和上网， 这要求手机需要支持两组芯片， 一组为 4G芯片， 另一组是 2G芯片， 所以功耗相 比传统模式会大一点。 而在设计 SGLTE方案时会面临一个很严重的问题， GSM 和 TDS/TDD LTE band共存问题， EGSM+TD dual talk组合中， EGSM与 TDD频段 距离较远， EGSM Tx通路加 LPF足以削弱 EGSM覆盖到 TDD频段的能量， 而特别 关注的是 DCS 1800和 TDS 39/TDD LTE B39共存为例子， DCS1800的发射和接收 频率分别为： 1710-1785Mhz， 1805-1880Mhz； 而 TDS/TDD LTE B39的频率范围 是 1880-1920Mhz。 GSM的发射频率接近 B39的接收频率， 所以会有部分的 block 能量覆盖到 B39; 而 B39的发射频率范围和 DCS1800的接收频率范围紧挨着， 更 会对 DCS有影响。 如果 DCS和 B39天线之间的隔离度不够大的话， 会存在导致严 重的耦合灵敏度劣化情况。
[0005] 因此， 5见有技术还有待于改进和发展

[0031] 图 2为本申请实施例提供的移动终端的具体结构框图。
发明实施例
本发明的实施方式
[0032] 本申请提供一种降低 SGLTE稱合灵敏度劣化的方法及移动终端， 为使本申请的 目的、 技术方案及效果更加清楚、 明确， 以下对本申请进一步详细说明。 应当 理解， 此处所描述的具体实施例仅仅用以解释本申请， 并不用于限定本申请。
[0033] 一种降低 SGLTE稱合灵敏度劣化的方法， 如图 1所示， 包括以下步骤：
[0034] S1、 将 GSM信号发射端发射信号中的 LTE网络频段滤除；
[0035] S2、 将接入 GSM信号接收端的信号中除 GSM网络频段之外的网络频段滤除。
[0036] 本申请通过将 GSM信号发射端发射信号中的 LTE网络频段滤除， 能够消除 GSM 信号对 LTE网络信号的干扰； 而将接入 GSM信号接收端的信号中除 GSM网络频 段之外的网络频段滤除， 使得 GSM信号接收端接收的只是 GSM网络频段信号， 隔绝了其他网络频段信号的对 GSM接收信号的干扰； 从而将频段接近导致的信 号干扰的问题消除， 极大地缓解 SGLTE稱合灵敏度劣化的现状。
[0037] 在降低 SGLTE稱合灵敏度劣化的方法中， 为了保证 GSM信号发射的性能， 在 步骤 S1中， 需要保证 GSM发射损耗尽可能小， 一般控制 GSM发射损耗小于 ldB
[0038] 具体地， 在步骤 S1中， 可以通过在 GSM发射通路中设置一带阻滤波器， 带阻滤 波器能够针对性地将 GSM信号发射端发射信号中的 LTE网络频段滤除， 而不会 滤除其他频段的网络信号， 因而能够消除 GSM发送发射信号对 LET信号接收的 干扰。 [0039] 在一些实施例中， 所述带阻滤波器在 1710-1785Mhz频段内直通， 而 1880-1920 Mhz频段内阻碍。 因为 DCS1800的发射和接收频率分别为 1710-1785Mhz与 1805-1 880Mhz； 而 TDS/TDD LTE B39的频率范围是 1880-1920Mhz， 即 GSM的发射频率 接近 B39的接收频率， 所以会有部分的 block能量覆盖到 B39， 而 B39的发射频率 范围和 DCS1800的接收频率范围紧挨着， 更会对 DCS1800有影响。 所以 DCS1800 和 B39的 de-sense fail情况时常发生， 其他的 de-sense情况基本可以忽略。 将带阻 滤波器设置在 1710-1785Mhz频段内直通而 1880-1920Mhz频段内阻碍， 即可针对 性滤除 0031800信号中的103 ）0 LTE B39频段信号。 其中， 所述带阻滤波器 可以将 1880-1920Mhz频段衰减至少 20dB。 对于 DCS1800 Tx影响 B39的灵敏度问 题， 如果使用低通滤波器， 其带外的抑制能力较差， 因而并不能够满足要求， 而使用带阻滤波器则能够满足要求。
[0040] 具体地， 将所述带阻滤波器设置于 GSM功率放大器与 GSM通路开关之间， 以 在滤除 GSM信号发射端发射信号中的 LTE网络频段的同时， 保证信号发射功率
[0041] 所述带阻滤波器由压电晶体振荡器材料组成， 所述的带阻滤波器需满足 GSM 1800发射频段带内差损小， 且 B34/39的带外抑制度足够高， 优选地， 所述带阻滤 波器由压电陶瓷、 铌酸锂和石英层叠制成。 声表滤波器主要是利用电信号转换 成机械信号， 再转换成电信号的工作原理。 而带阻滤波器的作用正好跟声表滤 波器相反。
[0042] 所述步骤 S2中， 在 GSM接收通路中设置 GSM接收滤波器， 以接收 GSM网络频 段信号， 并滤除掉 GSM信号接收端的信号中除 GSM网络频段之外的网络频段， 从而消除其他频段信号对 GSM通路接收 GSM信号的干扰。
[0043] TDS/TDD LTE B39的前端发射模块只有低通滤波器而不满足边带抑制的要求， 因而必须在 TDS/TDD LTE B39的发射通路使用的声表滤波器而 DCS1800的接收 通路使用窄带的声表滤波器。
[0044] 因而， 所述的降低 SGLTE稱合灵敏度劣化的方法中， 优选地， 还包括步骤： 将 LTE通路接收 /发射的信号中除 LTE网络频段之外的网络频段滤除。
[0045] 具体地， 可以在 LTE通路中设置一 LTE滤波器， 以将 LTE通路接收 /发射的信号 中除 LTE网络频段之外的网络频段滤除。 所述 LTE滤波器优选为接收 TDS/TDD LTE
B39和 B34频段的滤波器。 所述的 LTE滤波器为陶瓷滤波器。 优选地， 所述 LTE 滤波器设置于 LTE通路开关与天线之间。

[0047] 本领域普通技术人员可以理解上述实施例的各种方法中的全部或部分步骤是可 以通过程序来指令相关的硬件来完成， 该程序可以存储于一计算机可读存储介 质中， 存储介质可以包括： 只读存储器 (ROM, Read Only Memory) 、 随机存 取记忆体 (RAM， Random Access Memory) 、 磁盘或光盘等。
[0048] 基于上述方法， 本申请还提供了一种移动终端， 其中， 所述移动终端具有 SGL TE通信功能； 在 GSM发射通路中设置有带阻滤波器， 将 GSM发射端发射信号中 的 LTE网络频段滤除； 在 GSM接收通路中设置有 GSM接收滤波器， 以将接入 GS M信号接收端的信号中除 GSM网络频段之外的网络频段滤除。
