为了更清楚地说明本发明实施例或现有技术中的技术方案，下面将对实施 例或现有技术描述中所需要使用的附图作筒单地介绍，显而易见地， 下面描述 中的附图仅仅是本发明的一些实施例， 对于本领域普通技术人员来讲，在不付 出创造性劳动的前提下， 还可以根据这些附图获得其他的附图。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清 楚、 完整地描述， 显然， 所描述的实施例仅仅是本发明一部分实施例， 而不是 全部的实施例。基于本发明中的实施例， 本领域普通技术人员在没有作出创造 性劳动前提下所获得的所有其他实施例， 都属于本发明保护的范围。 并且， 以 下各实施例均为本发明的可选方案，实施例的排列顺序及实施例的编号与其优 选执行顺序无关。
如下表 1和表 2分别是根据基站和用户干扰要求进行的确定性分析，最 终得到的隔离距离要求指标。
如表 1所示，可以看到宏基站与宏基站间隔离距离要求非常苛刻，很难 实现不同的上下行配置。 而异构网络中如果家庭基站部署于宏小区边缘， 加之一些干扰规避的方法， 宏基站和家庭基站间的干扰基本是可控的。
如表 2所示，当上下行配置与宏小区不同的家庭基站布放在宏小区边缘 时， 同样位于宏小区边缘的宏用户则拥有较大的上行发射功率 （最大 23dBm ),可能会对家庭用户产生较强干扰，用户间隔离距离要求在数十米。 因此在通过适当的干扰控制方法， 在未来可以通过分层异构网络来实现基 站间采用不同的上下行配置。

以下结合附图， 以高层次基站为 MBS , 低层次基站为 HeNB为例， 对 本发明进行详细说明。
方法实施例一
如图 1所示， HeNB部署于 MBS的边缘。 如图 2所示， 本发明基站上 下行时隙配置方法实施例可包括以下步骤：
步骤 102, HeNB测量同频或邻频的 MBS的导频信号强度；
步骤 104, 选取其中导频信号强度最大的 MBS;
步骤 106,检测 MBS的上下行时隙配置，可通过监听空口消息 （TS36.331 6.2.2中 SIB1中的 TDD-Config)、 X2接口或网管数据获取 MBS的上下行时隙 配置；
步骤 108, 将该最大的导频信号强度与预设门限值进行比较；
步骤 110, 当该最大的导频信号强度低于门限值时， 将 HeNB与该 MBS 的下行时隙的时隙编号相同的部分下行时隙配置为上行时隙， 或将 HeNB 与 MBS的上行时隙的时隙编号相同的部分上行时隙配置为下行时隙；
如下表 3所示， 其中， D表示下行时隙， U表示上行时隙， S表示特殊 时隙。 当最大的导频信号强度低于门限值 a时， 将 HeNB与该 MBS的下行时 隙的时隙编号相同的部分下行时隙配置为上行时隙， 例如 MBS采用上下行配 置标号 1的方式， HeNB可以使用上下行配置标号 0, 这样 HeNB配置时隙编 号 4和 9的时隙为上行时隙。 当最大的导频信号强度低于门限值 a时， 将 HeNB与 MBS的上行时隙的 时隙编号相同的部分上行时隙配置为下行时隙。 例如 MBS采用上下行配置标 号 1的方式， HeNB可以使用上下行配置标号 2, 这样 HeNB配置时隙编号 3 和 8的时隙为下行时隙。
表 3
Figure imgf000009_0001
步骤 112, 当测得的最大导频信号强度等于或高于预设的门限值时， 将 HeNB的上下行时隙配置保持不变。
本实施例的方法， HeNB通过测量 MBS的导频信号强度， 将导频信号强 度与预设的门限值进行比较， 当低于门限值时， 设置 HeNB与 MBS的上下行 时隙配置不同。 这样， 在不提高基站之间的干扰的前提下， 实现了不同层次基 站间的不同上下行配置方式， 提高频语使用效率， 并且方法筒单有效， 易于实 现。
另外， 本实施例中， HeNB对上下行时隙的配置还取决于自身的上下行业 务量比例。 该方法还包括： HeNB测量自身的上下行业务数据量并计算上下行 业务数据量比例； 根据所述比例调整 HeNB 的上下行时隙配置。 使得 HeNB 的上下行时隙比例与其业务数据量比例接近。
例如， HeNB的上下行时隙配置比为 6:2, 而其上下行业务数据量比例约 为 1:1 , 这时候 HeNB可以将与 MBS的下行时隙的时隙编号相同的部分上行 时隙配置为下行时隙， 使得 HeNB上下行时隙配置变成 4:4, 接近上下行业务 数据量比例。 如上表 3所示， 第一行的基站上下行时隙比例为 6:2, 第二行的 基站上下行时隙比例为 4:4, 这两个基站在第 4和第 9个子帧（或时隙）交叉。 本实施例，通过根据 HeNB上下行业务量比例对其上下行时隙比例进行配 置， 使得上下行时隙比例与其的业务数据量比例接近， 提高了频语使用效率。 方法实施例二
如图 3 所示， 本发明另外一个上下行时隙配置方法实施例主要对宏基站 ( MBS )进行改进， 包括以下步骤：
步骤 202, MBS检测相邻的 HeNB的上下行时隙配置； MBS通过监听 X2 接口或网管数据获取 MBS覆盖区域内的 HeNB的上下行时隙配置信息；
步骤 204, MBS将 HeNB的上下行时隙配置与自身的上下行时隙配置进 行比较， 得到上下行交叉时隙； 如图 4所示， MBS和 HeNB在第 3和第 8号 时隙存在上下行交叉情况： MBS 为上行时隙， HeNB 为下行时隙， 此时存在 宏用户发射干扰家庭用户接收， HeNB发射干扰 MBS接收的情况；
步骤 206, 在交叉时隙， 以用户信道条件从高到低的顺序调度 MBS下的 用户， 优先调度信道条件好的 MBS下的用户； 和 /或若 MBS获得存在该交叉 时隙的 HeNB的位置信息，也可以优先调度远离 HeNB的用户；这样宏用户离 家庭用户距离较远， 宏用户受到干扰较小；
步骤 208, 在非交叉时隙， MBS正常调度用户。
当 MBS检测到多个相邻的 HeNB时， 逐个将 HeNB的上下行时隙配置与 自身的上下行时隙配置进行比较， 得到所有上下行交叉时隙。
本实施例中， MBS 通过在交叉时隙根据用户信道条件调度用户， 避免了 用户间的干扰， HeNB对 MBS的干扰导致的灵敏度下降也不会影响到宏用户 的体验。
上述方法实施例一和二可以结合起来实施， 也可以分别单独实施。 基站实施例一

本实施例的基站， 通过测量高层次基站的导频信号强度， 将导频信号强 度与预设的门限值进行比较， 当低于门限值时，设置该基站与高层次基站的上 下行时隙配置不同。 这样， 在不提高基站之间的干扰的前提下， 实现了不同层 次基站间的不同上下行配置方式， 提高频语使用效率， 并且方法筒单有效， 易 于实现。
另外， 通过根据 HeNB上下行业务量比例对其上下行时隙比例进行配置， 使得上下行时隙比例与其的业务数据量比例接近， 提高了频语使用效率。 基站实施例二
基于上述发明构思， 与方法实施例二对应地， 本发明还提供一种基站， 该 基站作为高层次基站使用， 即可以作为宏基站使用， 如图 6所示， 该基站 60 包括：
配置信息检测模块 61 , 用于检测相邻的低层次基站的上下行时隙配置； 比较模块 62, 用于将低层次基站的上下行时隙配置与基站自身的上下行 时隙配置进行比较， 得到上下行交叉时隙；
调度模块 63 , 用于在交叉时隙， 优先调度信道条件好的基站下的用户， 和 /或在交叉时隙， 获取存在该交叉时隙的低层次基站的位置信息， 优先调度 远离所述低层次基站的用户。
本实施例中， 该基站通过在交叉时隙根据用户信道条件调度用户，避免了 用户间的干扰， HeNB对 MBS的干扰导致的灵敏度下降也不会影响到宏用户 的体验。
另夕卜，基站通过优先调度远离低层次基站的用户，宏用户与家庭用户距离 较远， 家庭用户受到干扰较小。
可以理解的是， 本实施例的基站 60的各功能模块的功能可根据上述方法 实施例中的方法具体实现，其具体实现过程可以参照上述方法实施例的相关描 述， 此处不再赘述。 系统实施例一

更优地，该系统中， MBS检测相邻的 HeNB的上下行时隙配置；将 HeNB 的上下行时隙配置与自身的上下行时隙配置进行比较， 得到上下行交叉时隙； 在交叉时隙， 以用户信道条件从高到低的顺序调度 MBS下的用户， 和 /或在交 叉时隙， 若获得存在该交叉时隙的 HeNB 的位置信息， 优先调度远离 HeNB 的用户
本实施例中， 高层次基站 （MBS )通过在交叉时隙根据用户信道条件调 度用户，避免了用户间的干扰，低层次基站对高层次基站的干扰导致的灵敏度 下降也不会影响到高层次基站用户的体验。
