Description

一种设备内共存干扰协调的处理方法和设备 本申请要求于 2011 年 3 月 7 日提交中国专利局, 申请号为 201110053819.0, 发明名称为 "一种设备内共存干扰协调的处理方法 和设备"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
本发明涉及通信技术领域,尤其涉及一种设备内共存干扰协调的 处理方法和设备。 背景技术
( 1 ) ICO ( In-device Coexistence, 设备内共存 )介绍
迅速增长的智能终端市场要求在一个设备内同时支持多种无线 技术,例如,将 LTE( Long Term Evolution ,长期演进)和 ISM( Industrial Scientific and Medical ), LTE和 GPS ( Global Positioning System, 全 球定位系统) 集成到同一个设备上。 其中, ISM原是指分配给工业、 科学和医药的频段, 用于科学研究的非授权频段, 在此指使用该频段 的技术, 包括 WLAN ( Wireless Local Area Networks , 无线局域网) 和 Blue tooth (蓝牙 )等无线终端上的典型无线技术。
具体的, 在频率规划中, 一部分 TD-LTE频段以及 FD-LTE的上 行频段和 ISM的频段相邻, 如图 1所示的 LTE与 ISM相邻的频段示 意图, 同时一部分 LTE频段还与 GPS频段相邻。 其中, Band (频段 ) 40 ( 2300MHz-2400MHz )和 ISM ( e.g. 2.4GHz-2.4835GHz for WLAN ) 相邻; Band 7 ( 2500~2570MHz ), FDD ( Frequency Division Duplexing , 频分双工 ) UL (上行 )与 ISM相邻; Band 13 ( 777-787 MHz, 746-756 MHz ) /Band 14 ( 788-798 MHz , 758-768 MHz )与 GPS频段 (e.g. 1575.42MHz )相邻。
另外, 当不同的无线技术频段相邻时, 一个系统的发送操作会对 另一个系统的接收操作造成干扰, 如图 2所示的设备内共存的干扰 示意图, 紧密相邻的频段, 如 LTE band40 的高频 20MHz ( 2380-2400MHz ) 对 ISM 会造成强干扰, ISM 的低频 20MHz ( 2400-2420MHz )对 LTE会造成强干扰, LTE band 7低频 20MHz ( 2500-2520MHz )对 ISM会造成强干扰。
非紧邻频段也可能有谐波干扰, 例如, 如果蓝牙技术在低端频带 发射时, 对 TD-LTE频带上的泄露功率为 -50dBm , TD-LTE接收信号 功率设计为 -70dBm, 则在考虑热噪声及多径干扰前, LTE系统的 SIR ( Signal to Interference Ratio, 信号干 4尤比) 已经达到 -20dB, 显然不 能满足传输要求。
为了解决干扰问题, 设备内干扰的协调模式包括非协同 ( Uncoordinated mode )、 UE ( User Equipment , 用户设备 ) 内十办同 ( Coordinated within UE only ) 和网络侧辅助的 UE 内协同 ( Coordinated within UE and with network ),不同的模式具有不同的设 备影响和信令影响。
另外, 设备内共存干扰协调可以有 FDM ( Frequency Division Multiplexing, 频分复用)和 TDM ( Time Division Multiplex, 时分复 用) 两个方向。 FDM是指将 LTE和其他无线系统调整到相互不干扰 的频段上工作, 包括调整 LTE频段和调整 ISM频段两种方式; TDM 是指 LTE 系统和其他系统以时分的方式在干扰频段上工作, 在一个 时间段内只有一个无线系统在进行数据收发。
具体的, 在 FDM下, UE的 LTE系统和其他无线系统工作在互 不干扰的频段, LTE系统的调度、 测量、 切换与其他无线系统工作完 全独立。在 TDM下, LTE系统和其他无线系统采用时分的方式工作, LTE工作的时段称为调度周期( scheduling period )或开启周期 (ON duration ), 其他无线系统工作的时段称为 LTE 系统的非调度周期 ( unscheduled period )或关闭周期 ( OFF period )或工作间隙( gap )。
TDM干扰协调方式下, LTE系统的非调度周期可达到 60~100ms; 对于 LTE系统来说, 静态 TDM模式(即调度周期和非调度周期长度 固定)有以下问题: 当 UE检测到链路质量变差, 需要上报测量报告 以触发切换时,可能由于非调度周期限制不能及时获取资源发送测量 报告; 而由于非调度周期限制, eNB (基站)可能不能及时给 UE发 送切换命令, 导致 LTE链路质量恶化, 甚至切换失败; 而由于业务 的变化,原有的 TDM模式可能已经不能满足新建立的 LTE业务的时 延和速率要求。
( 2 ) ICO TDM介绍
当前 ICO TDM方式下,采用 LTE DRX( Discontinuous Reception, 非连续接收 )机制, 使用 LTE DRX的 active time (激活时间 )和 non active time(非激活时间)作为 TDM方案中的调度周期和非调度周期, 从而达到 ISM band上其他技术传输和 LTE系统传输的共存。
具体的, 考虑到当前的 TDM业务模型中调度周期和非调度周期 是有规则的固定 pattern (模式), LTE DRX机制中, active time是半 动态的 pattern, 受到网络侧配置的固定 pattern (即 onDurationTimer 和 DRX cycle )、 动态数据传输、 数据重传、 上行数据传输请求( SR 及 RACH过程) 的影响, 因此当前的 LTE TDM方案为一种增强的 DRX机制。
( 3 ) LTE DRX机制的配置方式
现有协议中, DRX机制是可选机制,即通过 RRC( Radio Resource Control, 无线资源控制)信令配置开启或关闭该功能, 具体信令方式 如下:
HAC-HainConf ig :: = SEQUENCE {
ul-SCH-Conf ig SEQUENCE { d x-C nfig - Need t imeAl igninentTiinerDedicatei d TimeAl ignrtien -Tinier ,
- ASN1STOP 在实现本发明的过程中,发明人发现现有技术中至少存在以下问 题:
