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做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。
需要说明的是， 本发明实施例可以应用于如图 1 所示的无线网 络中。 基于原有的无线网络， 本发明实施例所应用的无线网络中增 加了小小区 （ Small Cell ) (如： 第一小区 ） 的覆盖， 用以提高网络 容量的覆盖， 进而提高用户体验。
如图 1所示， 在本发明实施例中， 可以通过控制器（ Controller ) 连接 Small Cell接入点 （ Access Point , AP ) ( 即本发明实施例中的 第一小区设备） 与宏基站 （第二小区设备 ) , 如演进型基站 （ evolved Node B , eNB )。 其中， 控制器可以接受宏基站的控制， 控制器具备 无线资源管理 （ Radio Resource Management , RRM ) 功能和高层信 令功能， 可以通过与小小区 AP 之间的数据交互， 协调调度宏基站 覆盖范围内各个小小区中用户设备的通信资源。 其中， 控制器与各 个小小区 AP (第一小区设备） 之间通过回程线路 （ Backhaul ) 相连 接， 该回程线路为本发明实施例中为控制器对各个小小区 AP (第一 小区设备中的用户设备进行统一调度时， 控制器和小小区 AP 之间 传输调度数据专门配置的通信链路， 因此可以避免由于其他的数据 传输占用链路导致该调度数据传输时延较大的问题， 可以减小该调 度数据的传输时延。 其中， 控制器可以为小小区分簇后， 同簇的小 小区 AP中的一个小小区 AP , 此时控制器（一个小小区 AP )可以对 该小小区 AP 所在的小小区中的用户设备和同簇的其他小小区中的 用户设备进行联合的资源调度。
示例性的， 具体的小小区网络部署可以包括以下三种场景： 场景一： 宏小区 （第二小区 ） 与小小区 （第一小区 ） 同频， 例 如宏小区和小小区工作频率都为 F l。 如图 2或图 3所示， 同簇小小 区 AP (第一小区设备） 之间存在连接。 在该场景中， 如图 2所示， 一个簇内的小小区控制器可以是与宏基站 （第二小区设备） 相连接 的小小区 AP ; 进一步的， 如图 3所示， 一个簇内的小小区控制器也 可以是重新部署的具有 RRM功能的通信设备。 其中， 控制器可以与 同簇内的每个小小区 AP (第一小区设备） 直接相连。 如图 2或者图 3所示， 控制器也可以与一个小小区 AP (第一小区设备） 相连， 并 通过该小小区 AP连接同簇其他小小区 AP。
场景二： 宏小区 （第二小区 ） 与小小区 （第一小区 ） 异频， 例 如宏小区工作频率都为 F 1 , 小小区工作频率都为 F2。 如图 4或图 5 所示， 同簇小小区 AP (第一小区设备）之间存在连接， 在该场景中， 一个簇内的小小区控制器可以是与宏基站 （第二小区设备） 相连接 的小小区 AP ; 进一步的， 一个簇内的小小区控制器也可以是重新部 署的具有 RRM功能的通信设备。 需要说明的是， 在场景二中， 如图 4所示， 工作频率都为 F2的小小区 （第一小区 ） 可以在工作频率都 为 F 1 的宏小区 （第二小区 ） 之外。 如图 5 所示， 工作频率都为 F2 的小小区 （第一小区 ） 也可以包含于工作频率都为 F 1 的宏小区 （第 二小区 ） 之内。
场景三： 如图 6所示， 小小区 AP (第一小区设备） 可以不与宏 基站 （第二小区设备） 连接。 在该场景中， 一个簇内的小小区控制 器可以是与其他小小区 AP存在直接或间接连接的小小区 AP; 进一 步的，一个簇内的小小区控制器也可以是重新部署的具有 RRM功能 的通信设备。 在这种场景中， 宏小区 （第二小区 ） 与小小区 （第一 小区 ） 可以同频也可以异频。 实施例 1
本发明实施例提供一种资源调度方法， 如图 7所示， 包括：
S 101、 控制器联合调度至少两个第一小区覆盖范围内的用户设 备， 为用户设备分配资源， 并生成调度结果。
其中， 调度结果包括： 上下行物理资源块 （ Physical Resource Block , PRB ) 分配信息和用户设备的上行发射功率控制信息。
在本发明实施例的第一种应用场景中， 如图 3 所示， 控制器可 以为重新部署的具有 RRM功能的通信设备。
