Description

一种传输系统信息的方法、 系统及装置 技术领域
本发明涉及通信领域中的 MTC通信技术,尤其涉及一种传输系统信息 的方法、 系统及装置。 背景技术
机器类型通信用户终端 ( MTC UE, Machine Type Communication User Equipment ), 又称 M2M用户通信设备, 是现阶段物联网的主要应用形式。 低功耗低成本是其可大规模应用的重要保障。 智能抄表(smart metering ) 类设备是 MTC设备最典型的应用之一。 大多数智能抄表类 MTC设备, 都 固定安装在地下室等低覆盖性能环境下。为了保证此类 MTC设备能和基站 系统保持正常的通讯, 通常需要部署额外的站点、 中继器(Relay )等设备, 这无疑会大大增加运营商的部署成本。智能抄表类 MTC设备主要发送小包 数据, 对数据速率的要求低, 能够容忍较大的数据传输时延。
由于智能抄表类 MTC设备对数据速率要求极低, 对于数据信道而言, 可以通过更低的调制编码速率、 以及时域上的多次重复发送等方式, 来保 证小包数据的正确传输。对于需要向终端发送的系统帧序号信息, 目前 LTE 系统中的帧序号信息包含在主系统信息 (MIB ) 中, 发送 MIB的调度周期 是 40ms, 40ms内 MIB在各无线帧的子帧 0上的广播信道上发送 4次; 如 图 1所示, 分别为系统信息编码块 1、 系统信息编码块 2、 系统信息编码块 3和系统信息编码块 4,每一个系统信息编码块携带完整的 MIB信息,可以 独立解码。 每 40ms中的 MIB消息是保持不变的, 下一个 MIB消息中系统 帧序号 (SFN )会发生变化。
为了提升 MTC终端的覆盖性能,保证此类设备能正常与基站系统进行 通信, 需要在 40ms调度周期内增加主系统信息的发送次数。 此外, 对于一 些处于低覆盖环境下的传统用户终端而言, 也需要增加系统信息的发送次 数, 从而保证终端设备能正常维持与基站系统通信。 由于不同小区中低覆 盖用户终端所需的覆盖增强要求不同, 且同一小区下的低覆盖用户终端所 需要的覆盖增强等级也可能存在不同; 需要针对不同等级的覆盖增强需求 设计相应的系统信息的发送, 以保证用户终端正确接收相应的系统信息。 发明内容

其中系统信息传输周期包含 4个无线帧。 高覆盖增强等级对应的系统 信息重复发送资源包含低覆盖增强等级对应的系统信息重复发送资源, 其 中, 高覆盖增强等级对应大重复次数, 低覆盖增强等级对应小重复次数。 本实施例中多覆盖增强等级对应的系统信息重复发送资源分配如图 8所示, 在本实施例中, 共包含 3种覆盖增强等级, 重复传输次数是 4的倍数, 覆 盖增强等级一、 二、 三对应的重复次数依次是 4、 12和 36。 覆盖增强等级 一对应的系统信息重复发送资源如图 11 ( a )所示, 覆盖增强等级二对应的 系统信息重复发送资源包含覆盖增强等级一的系统信息重复发送资源, 如 图 11 ( b )所示; 覆盖增强等级三对应的系统信息重复发送资源包含覆盖增 强等级二的系统信息重复发送资源, 如图 11 ( c )所示。 当在一个系统信息 传输周期的一个子帧上需包含多于一个系统信息重复发送资源时, 所述系 统信息重复发送资源选择可釆用以下方式之一: 先子帧内选择, 再子帧间 (先预定义一个子帧可以重复传输的个数, 一个子帧映射满后, 再映射下 一个子帧), 或者, 先子帧间, 再子帧内 (如图 8所示, 一个无线帧中定义 5个子帧可用重复传输, 当超过 5次重复, 再在相同子帧内重复) 的方式。 在一个无线帧中选择包含系统信息重复发送资源按照预定义的子帧优先级 顺序选择; 可以针对最大重复次数选择上述预定义优先级的部分。 当所述 无线帧中一个子帧中仅包含一份系统信息重复发送资源时, 所述预定义的 子帧优先级顺序具体包括: 子帧优先级为 5, 9, 4, 8, 3, 7, 2, 6, 1 ; 或 者 5, 9, 4, 8, 3, 7, 6, 1, 2 , 或者 5, 9, 4, 8, 3, 6, 1, 7, 2; 或者, 5, 9, 4, 6, 1, 8, 3, 7, 2; 或者 5, 9, 8, 7, 6, 1, 4, 3, 2; 或者 5, 6, 1, 9, 4, 8, 3, 7, 2; 或者 5, 6, 1, 9, 8, 7, 4, 3, 2。
