图 9为 k在时分双工中的数值图。 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 有做出创造性劳动前提下所获得的所有其它实施例, 都属于本发明保护的 范围。
大多数集群业务主要发生在同一个基站下,所以可以利用 loca l swi tch 来实现集群业务的本地交换, 而无需消耗回程网的传输资源。 其过程如下: 第一用户设备要对第二用户设备进行数据传输, 首先需要通过緩冲区状态 才艮告 BSR (buffer s ta tus repor t)上才艮上传的数据量, 然后 eNB通过 PDCCH (phys ica l downl ink contro l channe l , 物理下行控帝 M言道)分西己适 当的上行授权(UL grant) , UE按照 UL grant的指示在上行共享信道(UL-SCH) 上进行上行数据的传输。 如果第一用户设备和第二用户设备在同一个小区, eNB把接收到上行数据直接放在下行緩冲区, eNB对第二用户设备进行下行 调度而无需涉及到核心网的交互。
简单地利用 1 oca 1 swi t ch技术实现同一个基站下的用户设备之间的数据 传输, 所有的数据传输都必须通过网络进行中转, 通信网络资源浪费严重。 为了解决上述技术问题, 本发明提供了一种用于终端直通模式的技术方案。
本发明所述的终端直通模式可以用于集群通信的直通呼叫 DM0模式, 也 可以用于通用的长期演进系统 LTE的终端直通 D2D通信。 由于直通模式可以 在网络的辅助下进行通信双方的直接数据传输, 所以可以节省宝贵的空口 资源。 为描述方便, 后续说明以更为广泛的 D2D通信为例。 为使本发明技术 方案的优点更加清楚, 下面结合附图和实施例对本发明作详细说明。
本发明提供一种业务调度方法, 如图 1所示, 所述方法包括:
101、 基站在用户设备建立连接时, 配置配对用户设备和配置在资源调 度中使用的组无线网络临时标识 Group RNTI。
其中, 所述配对用设备包括釆用终端直通模式进行通信的配对用户设 备, 所述配对用户设备包括至少两个用户设备, 所述至少两个设备中的一 个设备与除所述一个设备之外的其他用户设备对应。
具体地, 当所述一个用户设备为固定位置的小功率节点时, 所述基站 接收所述除所述一个设备之外的其他用户设备发起的业务请求。
根据所述业务请求, 所述基站获取与所述除所述一个设备之外的其他 用户设备位置最接近的所述一个用户设备, 并将所述一个用户设备和所述 除所述一个设备之外的其他用户设备进行配对。
可替换地, 当所述一个用户设备为固定位置的小功率节点时, 所述基 站向所述除所述一个设备之外的其他用户设备发送广播通知消息, 所述广 播通知消息包含所述固定小功率节点存贮的用于获取与所述固定小功率节 点类别相同的所述其他用户设备的内容分类索引和所述在资源调度中基站 用于加扰发送资源授权和接收资源分配的 Group RNTI , 以使得所述除所述 一个设备之外的其他用户设备直接根据所述广播通知消息获取与所述除所 述一个设备之外的其他用户设备配对的一个用户设备。
102、 所述基站接收所配对用户设备中的一个用户设备通过緩冲区状态 报告发送的所述一个用户设备需要上传的数据量。
103、 所述基站在同一个物理下行控制信道向所述一个用户设备发送发 送资源授权的同时, 向除所述一个设备之外的其他用户设备发送接收资源 分配。
其中, 所述基站向所述除所述一个设备之外的其他用户设备发送的所 述发送资源授权和向所述一个用户设备发送的接收资源分配包括的控制信 息内容完全相同, 所述发送资源授权和所述接收资源分配为所述基站通过 所述 Group RNTI加 4尤的。
104、 所述基站指示所述一个用户设备根据所述发送资源授权和指示所 述除所述一个设备之外的其他用户设备根据所述接收资源分配进行终端直 通模式数据的通信。
在进行终端直通模式通信时, 需要在物理下行控制信道中新增一个 DCI (Down l ink Cont ro l Inf orma t ion,下行控制信息)格式, 用于终端直 通模式数据的识别。 由于终端直通模式数据的资源分配通过基站进行分 配, 所以终端直通模式数据的 DC I格式不用携带资源配置(resource a l loca t ion) , 调制编码方式 (MCS : modula t ion and coding scheme)等 信息, 这些信息在步骤 103中已经配置好。
所述终端直通模式数据所在子帧的物理下行控制信道是所述一个用户 设备通过所述 D-RNTI加扰的, 用于所述除所述一个设备之外的其他用户设 备判断所述终端直通模式数据是否由所述一个用户设备发送的。 本发明中的第二用户设备也可以为 n个, n为正整数。 此时, 所述基站 指示所述第一用户设备根据所述发送资源授权和第二用户设备根据所述接 收资源分配进行终端直通模式数据的通信。

所述终端直通模式数据所在子帧的物理下行控制信道是所述一个用户 设备通过所述 D-RNTI加扰的, 用于所述除所述一个设备之外的其他用户设 备判断所述终端直通模式数据是否由所述一个用户设备发送的。
