MUCC的通信协议栈与传统 LTE ( Long Term Evolution, 长期演进 )协议 栈有所区别， MUCC协议栈需要添加一个合成层， 利用短距离无线通信方式 进行数据传输。在现有技术中，该合成层添加在 PDCP( Packet Data Convergence Protocol,分组数据汇聚协议）层之上，或者添加在 PDCP层与 RLC( Radio Link Control, 无线链路控制）层之间。
基于上述协议栈结构， eNB可以根据上行信道的质量， 设置两 UE中数据 的分流策略， B-UE先生成需要发送的数据并分流至 S-UE保存， S-UE向 eNB 请求发送上行数据， eNB根据 S-UE的上行数据发送请求向 S-UE发送上行数 据许可后， S-UE才能发送数据。从 B-UE生成需要发送的数据到 S-UE发送数 据中间有较大的时延， 到 S-UE发送 B-UE的数据时， 可能 S-UE的上行信道 质量已经发生变化， 当时的分流策略可能已经不再适用， 分流策略调整不够及 时。 发明内容
本发明实施例提供了一种上行数据调度方法、 基站及用户设备， 以实现 多 UE合成通信中上行数据的及时调度。

为了使本技术领域的人员更好地理解本发明方案，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的实施例， 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， 都应当属于本发明保护的范围。 本发明实施例的上行数据调度方法及基站可以应用于 FDD LTE网络， LTE ( Long Term Evolution,长期演进技术 )网络可以包括 TDD ( Time Division Duplexing, 时分双工)、 FDD ( Frequency Division Duplexing, 频分双工)两种 双工模式， 应用 FDD式的 LTE即为 FDD-LTE。 本发明实施例的上行数据调 度方法及基站， 可以应用的场景包括但不限于 MUCC***以及 MU-MIMO ( Multi-User Multiple-Input Multiple-Output, 多用户多输入多输出） ***。 在 介绍本发明实施例的具体技术方案之前， 下面先对 MUCC ***以及 MU-MIMO***进行简单介绍。
MUCC***以及 MU-MIMO***均可以认为是多 UE协作通信***， 参见图 1所示，是一种 MUCC或 MU-MIMO***的结构示意图， 其中基站 eNB 10调度两用户设备 UE20向基站发送上行数据， 两 UE间可以通过短距 离无线通信方式通信。 MUCC***中， 两个 UE间具有合成通信关系， 当有 数据需要发送时一 UE可以利用另一 UE转发其需要发送的数据， 起转发作 用的 UE为 S-UE, 目的 UE为 B-UE。 而 MU-MIMO***中， 两个 UE均可 以作为 B-UE, 也可以作为对方的 S-UE, 与 eNB 均处于同步态， 即这些 UE可以看成一个拥有多根天线的大 UE, 每个子 UE可以利用相同的时频 资源发送上行数据， 在子 UE发送上行数据前，每个子 UE均需要拥有所要 发送的数据。
实现 MUCC或 MU-MIMO技术时， 协议栈需要添加一个合成层。 B-UE 上的合成层的主要功能是数据包分流以及通过短距离无线通信方式将数据包 传送给 S-UE; S-UE上的合成层主要功能是通过短距离无线通信方式接收到来 自 B-UE的每个数据包， 并根据 S-UE合成层上添加的包头信息映射到 S-UE 上的某个合成承载上进行上行数据传输。现提出一种新的协议栈结构， 考虑将 合成层下移， 将合成层放在 MAC (Medium Access Control, 媒体接入控制） 层中， 当合成层下移到 MAC层时， 这时 UE间通过短距离无线通信方式传递 的则是 MAC PDU ( Protocol Data Unit, 协议数据单元）。
另外， 需要注意的是， MUCC***中每个 UE—个 TTI内只能生成一个 MAC PDU, 也只能发送一个 MAC PDU; 而 MU-MIMO***中每个 UE—个 TTI ( Transmission Time Interval, 传输时间间隔）内可以生成一个或两个 MAC PDU ,每对 UE可以协同发送共两个 MAC PDU ,即每对 UE各自生成一个 MAC PDU并协同上传， 或由一个 UE生成两个 MAC PDU与另一 UE协同上传， 但 当一个 UE自己上传 MAC PDU时 , 则与 MUCC***类似 , 一个 TTI内只能 生成一个 MAC PDU, 也只能发送一个 MAC PDU, 具体的， UE采用何种方 式上传数据均由基站进行调度。
构建形成图 1所示的 MUCC或 MU-MIMO***之后， 为了解决现有技 术中存在的上行数据分流策略调整不及时的问题， 同时由于合成层下移到 MAC层， MAC层没有緩存 buffer, 不能储存 MAC PDU, 因此 B-UE不能先 将数据分流至 S-UE存储，为此本发明实施例提供了如下的上行数据调度方法。
参见图 2所示，是本发明实施例中上行数据调度方法实施例 1的流程图， 本实施例可以应用于 MUCC***， 本实施例在基站实现该方法， 可以包括以 下步骤：
步骤 101 : 基站将上行调度信息发送给 S-UE和 B-UE, 以使 B-UE根据 上行调度信息生成需要发送的 MAC PDU并获得需要发送的 MAC PDU的 上传数据方式。
这里可以假定如下前提， 基站 eNB 已经知道各 UE的合成关系， 同时知 道 B-UE有数据需要发送以及需要发送数据的大小， UE间知道对方的 C-RNTI ( Cell Radio Network Temporary Identifier, 小区无线网络临时标识）。 则每一 个 TTI内基站可以调度 S-UE为 B-UE转发数据或由 B-UE直接向基站发送数 据。
具体的， 基站发送的上行调度信息内至少可以包括数据产生标识信息 以及数据发送提示信息。 数据产生标识信息可以提示由哪个 UE生成 MAC PDU以及生成 MAC PDU的数量， 由于本实施例应用于 MUCC场景， 则每 个 UE—个 TTI内只能根据数据产生标识信息生成一个 MAC PDU, 也只能发 送一个 MAC PDU。 数据发送提示信息则可以指示上行数据由生成数据的 UE 自行发送， 还是由 S-UE协同发送。 UE 自行向基站发送上行数据的过 程类似于传统上行数据直接发送方法， 因此， 本发明实施例重点介绍 B-UE 经过 S-UE向基站发送上行数据的调度方法。进一步的，上行调度信息还可 以包括接收标识信息， 接收标识信息可以提示由哪个 UE接收上行调度信 息。
那么， 基站将上行调度信息发送给 S-UE以及 B-UE, 则 B-UE可以根 据数据产生标识信息生成需要发送的 MAC PDU,根据数据发送提示信息获 得上传数据方式， 需要发送的 MAC PDU的上传数据方式可以为通过 S-UE 上传数据或直接上传数据。
步骤 102: 如果上传数据方式为通过 S-UE上传数据， 基站接收 S-UE 发送的 MAC PDU, S-UE发送的 MAC PDU是在 S-UE通过短距离无线通 信方式接收到 B-UE发送的 MAC PDU后获得的。
由于 MAC PDU需要在 UE获得上行调度信息后， 才能生成并传输， 本 发明实施例可以在 B-UE向 S-UE传输 MAC PDU完成后，基站 eNB直接接 收 S-UE上传的数据， 缩小了从 B-UE生成 MAC PDU到通过 S-UE向基站 发送数据之间的间隔，基站的调度对上行信道状况的变化能够及时做出调整。 短距离无线通信方式包括但不限于蓝牙、 wifi ( wireless fidelity, 无线保真） 等方式。
本方法实施例， 可以应用于 MUCC***， 另外， 利用基站发送上行调度 信息的方式，使 UE可以根据上行调度信息灵活进行数据上传， 实现基站灵活 调度上行数据的目的。 参见图 3所示，是本发明实施例中上行数据调度方法实施例 2的流程图， 包括：
步骤 201 : 基站将上行调度信息发送给 S-UE和 B-UE, 以使 B-UE根据 上行调度信息生成需要发送的 MAC PDU并获得需要发送的 MAC PDU的 上传数据方式。
步骤 202: 如果上传数据方式为通过 S-UE上传数据， 基站接收 S-UE 发送的 MAC PDU, S-UE发送的 MAC PDU是在 S-UE通过短距离无线通 信方式接收到 B-UE发送的 MAC PDU后获得的。
步骤 203: 在接收 S-UE发送的 MAC PDU后， 基站向 S-UE发送确认 信息 ACK ( Acknowledgement, 确认）， 或者， 向 S-UE发送否认信息 NACK ( Negative Acknowledgement , 否定性确认 ) , 以使 S-UE根据否认信息重新 发送 MAC PDU。
需要注意的是， S-UE接收到 B-UE发送的 MAC PDU后， 可以将接收 到的 MAC PDU送入相应的 HARQ ( Hybrid Automatic Repeat reQuest, 混合 自动请求重传）进程， 因此， 当基站反馈没有正确接收 S-UE发送的数据时， S-UE可以直接再次发送未能成功传输的数据。
步骤 204: 基站接收 S-UE重新发送的 MAC PDU。
步骤 201-202与步骤 101-102类似， 此处不再贅述。 与方法实施例 1 相比， 本实施例在基站接收 S-UE发送的 MAC PDU后， 进一步包括根据接 收到的 MAC PDU , 向 S-UE发送确认信息或否认信息， 以使 S-UE根据否 认信息重新发送 MAC PDU, 基站接收 S-UE重新发送的 MAC PDU, 以保 证上行数据的正确传输。 参见图 4所示，是本发明实施例中上行数据调度方法实施例 3的流程图， 本实施例可以应用于 MUCC***， 本实施例在 B-UE实现该方法， 可以包括 以下步骤：
步骤 301 : B-UE接收上行调度信息。
B-UE接收的上行调度信息可以至少包括：数据产生标识信息和数据发 送提示信息。
步骤 302: B-UE根据上行调度信息生成需要发送的 MAC PDU, 并获 得需要发送的 MAC PDU的上传数据方式。
具体的， B-UE可以根据数据产生标识信息生成需要发送的 MAC PDU; 根据数据发送提示信息确认需要发送的 MAC PDU的上传数据方式。
步骤 303:如果上传数据方式为通过 S-UE上传数据， B-UE将 MAC PDU 通过短距离无线通信方式发送给 S-UE, 以使 S-UE将 MAC PDU发送给基 站。
进一步的， 上行调度信息还可以包括接收标识信息， 根据接收标识信 息， B-UE可以接收基站发送的上行调度信息； 或者， B-UE接收 S-UE转 发的上行调度信息。 具体的， B-UE根据接收标识信息确认是否接收基站发 送的上行调度信息， 进一步的， B-UE根据接收标识信息确认自身存储的接 收标识信息中是否包括接收标识信息。
例如上行调度信息中携带 B-UE 的身份信息作为接收标识信息， 则 S-UE以及 B-UE均从基站接收该上行调度信息， 即 B-UE接收基站发送的 上行调度信息； 上行调度信息中携带 S-UE的身份信息作为接收标识信息， 则 S-UE从基站接收该上行调度信息， 并转发给 B-UE, 即 B-UE接收 S-UE 转发的上行调度信息。
本方法实施例， 可以应用于 MUCC***， 与上述方法实施例 1-2对应， 以 B-UE为执行主体， 利用基站发送上行调度信息， UE可以灵活进行数据上 传， 实现基站灵活调度上行数据的目的。 参见图 5所示，是本发明实施例中上行数据调度方法实施例 4的流程图， 本实施例可以应用于 MUCC***， 本实施例在 S-UE实现该方法， 可以包括 以下步骤：
步骤 401 : S-UE接收上行调度信息。
S-UE接收的上行调度信息可以至少包括： 数据产生标识信息和数据发 送提示信息。
步骤 402: S-UE根据上行调度信息确定上传数据方式。
步骤 403: 如果上传数据方式为通过 S-UE上传数据， 则 S-UE接收受 益用户设备 B-UE通过短距离无线通信方式发送的 MAC PDU, MAC PDU 为 B-UE根据上行调度信息生成的。
具体的， S-UE可以根据数据发送提示信息确定上传数据方式， 确定需 要发送的 MAC PDU的上传数据方式为通过 S-UE上传数据； S-UE接收 B-UE通过短距离无线通信方式发送的 MAC PDU之前还可以包括： S-UE 根据数据产生标识信息确认接收的 MAC PDU为 S-UE对应 B-UE生成的 MAC PDU。
步骤 404: S-UE将 MAC-PDU发送给基站。
进一步的， S-UE还可以向 B-UE转发上行调度信息。 上行调度信息还 可以包括接收标识信息， 则 S-UE可以根据接收标识信息确认是否向 B-UE 转发上行调度信息。例如上行调度信息中携带 S-UE的身份信息作为接收标 识信息， 则 S-UE从基站接收该上行调度信息， S-UE可以根据接收标识信 息确认向 B-UE转发上行调度信息。
本方法实施例， 可以应用于 MUCC***， 与上述方法实施例 1 -2对应， 以 S-UE为执行主体， 利用基站发送上行调度信息， UE可以灵活进行数据上 传， 实现基站灵活调度上行数据的目的。 基于方法实施例 1-4, 参见图 6所示， 是本发明实施例上行数据调度方 法实施例 5的流程图， 包括：
步骤 501 : 基站向 S-UE和 B-UE发送上行调度信息， 其中， 所述 B-UE 的身份信息作为接收标识信息和数据产生标识信息， 以使 S-UE以及 B-UE 接收上行调度信息， B-UE 根据数据产生标识信息生成需要发送的 MAC PDU,根据数据发送提示信息获得需要发送的 MAC PDU的上传数据方式。
当上行调度信息中携带 B-UE 的身份信息作为接收标识信息和数据产 生标识信息， 例如上行调度信息利用 B-UE的 C-RNTI加扰， 则 S-UE以及 B-UE均接收该上行调度信息。 当一个 B-UE与一个 S-UE对应时， 则上行 调度信息可以指示 B-UE是自己向基站上传数据还是通过 S-UE上传数据， 当一个 B-UE与多个 S-UE对应时， 则上行调度信息可以指示 B-UE是自己 向基站上传数据还是通过 S-UE上传数据， 具体的， 通过哪个 S-UE上传数 据。 当一个 B-UE与一个 S-UE对应时， 上行调度信息可以采用标志位指示 B-UE是自己向基站上传数据还是通过 S-UE上传数据； 而当一个 B-UE与 多个 S-UE对应时，数据发送提示信息可以包括 S-UE的 C-RNTI,也可以包 括预先配置的传输路径对应表， 表中包括 B-UE的每个 S-UE的索引值， 则 上行调度信息可以指示 B-UE是自己向基站上传数据还是通过哪个 S-UE上 传数据。
步骤 502: 如果上传数据方式为通过 S-UE上传数据， 基站接收 S-UE 发送的 MAC PDU, S-UE发送的 MAC PDU是在 S-UE通过短距离无线通 信方式接收到 B-UE发送的 MAC PDU后获得的。
步骤 503: 在接收 S-UE发送的 MAC PDU后， 基站向 S-UE发送确认 信息 ACK , 或者向 S-UE发送否认信息 NACK , 以使 S-UE根据否认信息 重新发送 MAC PDU。
步骤 504: 基站接收 S-UE重新发送的 MAC PDU。 与上述数据调度方法实施例 5 相对应的， 本发明实施例还提供一种上 行数据调度***实施例 1 , 包括基站 eNB、 B-UE以及 S-UE。 结合图 7所示 的信令交互示意图，对上述各个部分所起作用以及各部分间的信息交互过程进 行简单介绍。
步骤 601 : 基站向 S-UE和 B-UE发送上行调度信息， 其中， 所述 B-UE 的身份信息作为接收标识信息和数据产生标识信息， S-UE以及 B-UE均接 收该上行调度信息。
步骤 602: B-UE根据数据产生标识信息生成需要发送的 MAC PDU,根 据数据发送提示信息获得获得需要发送的 MAC PDU的上传数据方式。
步骤 603: 如果上传数据方式为通过 S-UE上传数据， B-UE通过短距 离无线通信方式向 S-UE发送 MAC PDU。
步骤 604: S-UE向基站发送 MAC PDU, 基站接收该 MAC PDU。
步骤 605: 基站向 S-UE发送确认信息 ACK或向 S-UE发送否认信息 NACK：。
步骤 606: 若 MAC PDU需要重传， S-UE根据否认信息重新向基站发 送 MAC PDU, 基站接收 S-UE重新发送的 MAC PDU。
在传统的调度方法中， 基站向 S-UE发送调度信息后到基站收到 S-UE 发送的上行数据的间隔是 4ms, 但是， 本发明实施例需要考虑 MAC PDU 在 UE间通过短距离无线通信的时间 , 假定 B-UE向 S-UE发送 MAC PDU 的转发延迟时间为 1ms,则本发明实施例基站向 UE发送调度信息后，在 5ms 后接收 MAC PDU。
需要注意的是，若假设基站向 UE发送上行调度信息的时刻为 N时刻， 当 B-UE的上传数据方式为通过 S-UE上传数据时， 则基站接收 S-UE发送 的 MAC PDU的时刻为 N+5时刻，那么基站需要避免在 N+1时刻调度 S-UE 在 N+5时刻直接向基站上传 S-UE 自己的数据。 同时， 具体的每一步骤发 生时刻可以根据实际情况进行设定， 图中仅仅给出的是一个示例， 本发明 实施例对此不作限定。 基于方法实施例 1-4, 参见图 8所示， 是本发明实施例上行数据调度方 法实施例 6的流程图， 包括：
步骤 701 : 基站向 S-UE和 B-UE发送上行调度信息， 其中， S-UE的身 份信息作为接收标识信息和数据发送提示信息，以使 S-UE接收上行调度信 息， 并向 B-UE通过短距离无线通信方式转发上行调度信息， B-UE根据数 据产生标识信息生成需要发送的 MAC PDU,根据数据发送提示信息获得需 要发送的 MAC PDU的上传数据方式。
当上行调度信息中携带 S-UE 的身份信息作为接收标识信息和数据发 送提示信息， 例如上行调度信息利用 S-UE的 C-RNTI加扰， 则仅 S-UE接 收该上行调度信息。 数据产生标识信息可以包括 B-UE的 C-RNTI, 也可以 包括预先配置的传输路径对应表， 表中包括 S-UE的每个 B-UE的索引值。 S-UE需要根据上行调度信息通过短距离无线通信方式向 B-UE转发上行调 度信息， B-UE则可以根据上行调度信息生成需要发送的 MAC PDU以及通 过 S-UE上传数据的上传数据方式。
步骤 702: 当上传数据方式为通过 S-UE上传数据时， 基站接收 S-UE 发送的 MAC PDU, S-UE发送的 MAC PDU是在 S-UE通过短距离无线通 信方式接收到 B-UE发送的 MAC PDU后获得的。
步骤 703: 在接收 S-UE发送的 MAC PDU后， 基站向 S-UE发送确认 信息 ACK, 或者， 向 S-UE发送否认信息 NACK, 以使 S-UE根据否认信 息重新发送 MAC PDU。
步骤 704: 基站接收 S-UE重新发送的 MAC PDU。
步骤 702-704与步骤 502-504类似， 此处不再贅述。 与方法实施例 5相 比， 本实施例上行调度信息中所携带的信息不同， 则仅有 S-UE接收该上行调 度信息， 由 S-UE向 B-UE转发上行调度信息， 完成后续的上行数据调度。 另 夕卜，由 B-UE与 S-UE同时接收上行调度信息或是由 S-UE接收上行调度信息， 再由 S-UE向 B-UE转发上行调度信息可以由基站在 UE间建立合成关系时配 置。 同样的， 与上述数据调度方法实施例 6相对应的， 本发明实施例还提供 一种上行数据调度***实施例 2, 包括基站 eNB、 B-UE以及 S-UE。 结合图 9所示的信令交互示意图， 对上述各个部分所起作用以及各部分间的信息交互 过程进行简单介绍。
步骤 801 : 基站向 S-UE和 B-UE发送上行调度信息， 其中， S-UE的身 份信息作为接收标识信息和数据发送提示信息，仅 S-UE接收该上行调度信 息。 步骤 802: S-UE向 B-UE通过短距离无线通信方式转发上行调度信息。 步骤 803: B-UE根据数据产生标识信息生成需要发送的 MAC PDU,根 据数据发送提示信息获得需要发送的 MAC PDU的上传数据方式。
步骤 804: 如果上传数据方式为通过 S-UE上传数据， B-UE通过短距 离无线通信方式向 S-UE发送 MAC PDU。
步骤 805: S-UE向基站发送 MAC PDU, 基站接收该 MAC PDU。
步骤 806: 基站向 S-UE发送确认信息 ACK或向 S-UE发送否认信息
NACK：。
步骤 807: 若 MAC PDU需要重传， S-UE根据否认信息重新向基站发 送 MAC PDU, 基站接收 S-UE重新发送的 MAC PDU。
假定 S-UE向 B-UE发送上行调度信息的转发延迟时间为 1ms, B-UE 向 S-UE发送 MAC PDU的转发延迟时间为 1ms,则本发明实施例基站向 UE 发送调度信息后， 在 6ms后接收 MAC PDU。 需要注意的是， 具体的每一 步骤发生时刻可以根据实际情况进行设定， 图中仅仅给出的是一个示例， 本发明实施例对此不作限定。 在上述各个实施例的基础上， 基站 eNB调度 B-UE通过 S-UE转发数据， 但此时 B-UE与 S-UE间的短距离无线通信链路质量可能不好， B-UE的 MAC PDU也许不能成功传输。 因此， 在 S-UE侧可以设置一个对应的计时器， 若超 时前接收到来自 B-UE的 MAC PDU则正常转发， 同时停止计时器； 若计时器 超时， 则认为 B-UE以及 S-UE间短距离无线通信链路已断， 不必继续等待， 丟弃之前保存的上行调度信息。 这样基站 eNB分配的上行时频资源就是空白 的， 可以通过这种方式隐式通知基站 eNB转发不成功， 则基站 eNB不必要求 重传。
进一步的， 当 S-UE的计时器超时时， S-UE可以构造一个 MAC PDU, 其 中包含一个特殊的 MAC CE ( MAC Control Element, MAC控制元素）， 其余 为填充位。 该 MAC PDU在基站 eNB指定的上行时频资源上发送。 当基站接 收到该 MAC PDU时， 通过读取其中这个特殊的 MAC CE即可获知 B-UE到 S-UE数据转发不成功。
进一步的， 当 S-UE的计时器超时时， S-UE生成一个自己的 MAC PDU, 其中包含自己的身份信息，如一个标志位，或者一个包含自己 C-RNTI的 MAC CE,通过这种方式来告知 eNB是 S-UE的数据，而不是 B-UE的。该 MAC PDU 在 eNB指定的上行时频资源上发送。 当基站接收到该 MAC PDU时， 通过读 取其中的 S-UE的身份信息， 则可以获知此 MAC PDU是 S-UE的数据， 不是 转发 B-UE的数据， 获知 B-UE到 S-UE数据转发不成功。
另外， B-UE还可以获知与 S-UE 间的短距离无线通信链路质量不好或 B-UE的 MAC PDU未成功发送到 S-UE,则 B-UE可以利用之前接收到的上行 调度信息自己将数据发送给基站 eNB。
以上的几种情况还可以用于基站检测 UE间短距离无线通信链路质量。
本实施例可以应用于 MU-MIMO ***， 本实施例在基站实现该方法可以包括 以下步骤：
步骤 901 :基站向第一 UE和第二 UE发送上行调度信息， 以使第一 UE 和 /或第二 UE根据上行调度信息生成需要发送的 MAC PDU。
这里可以假定如下前提， 基站 eNB 已经知道各 UE的合成关系， 也知道 哪个 UE有数据需要发送以及需要发送数据的大小，UE间知道对方的 C-RNTL 则每一个 TTI内由单 UE发送数据或多 UE联合发送由基站进行调度。
具体的， 上行调度信息可以至少包括数据产生标识信息以及数据发送 提示信息。数据产生标识信息可以提示由哪个 UE生成 MAC PDU以及生成 MAC PDU的数量 , 由于本实施例应用于 MU-MIMO场景 , 则每个 UE—个 TTI内能够根据数据产生标识信息生成一个或两个 MAC PDU。数据发送提示 信息则可以指示上行数据由生成数据的 UE自行发送，还是由两 UE协同发 送， 具体的与哪个 UE协同发送。 同样的， 本发明实施例重点介绍两 UE协 同向基站发送上行数据的调度方法。
那么， 基站向第一 UE以及第二 UE发送上行调度信息， 则第一 UE和 / 或第二 UE根据数据产生标识信息生成需要发送的 MAC PDU,根据数据发 送提示信息获得上传数据方式。
步骤 902: 基站接收第一 UE与第二 UE通过 MU-MIMO通信方式协同 发送的 MAC PDU, MAC PDU是在第一 UE与第二 UE通过短距离无线通 信方式共享后获得的； MU-MIMO通信方式是第一 UE与第二 UE根据上行 调度信息查找自身存储的上传数据方式确定的。
由于 MAC PDU需要在 UE获得上行调度信息后， 才能生成并传输， 本 发明实施例可以两 UE共享 MAC PDU完成后， 基站直接接收两 UE协同上 传的数据，缩小了从 UE生成需要发送的数据 MAC PDU到通过另一 UE协 同向基站发送数据之间的时间间隔。
与方法实施例 1相比， 本方法实施例， 可以应用于 MU-MIMO***， 并 不区分 S-UE与 B-UE, 当两 UE协同上传数据时， 基站可以调度两 UE中的 任一个在一个 TTI内生成两个 MAC PDU, 再由两 UE协同上传这两个 MAC PDU, 也可以调度第一 UE与第二 UE各生成一个 MAC PDU, 再由两 UE协 同上传这两个 MAC PDU。 当协同上传数据时， 两 UE需要先共享所需要发 送的 MAC PDU, 再协同向基站发送 MAC PDU。 需要注意的是， 当 UE自 己直接向基站上传数据时， 则基站只能调度 UE在一个 TTI内上传该 UE生 成的一个 MAC PDU, 此过程与现有技术类似。
包括：
步骤 1001: 基站向第一用户设备 UE和第二 UE发送上行调度信息， 以 使第一 UE和 /或第二 UE根据上行调度信息生成需要发送的 MAC PDU。
步骤 1002: 基站接收第一 UE与第二 UE通过 MU-MIMO通信方式协 同发送的 MAC PDU, MAC PDU是在第一 UE与第二 UE通过短距离无线 通信方式共享后获得的； MU-MIMO通信方式是第一 UE与第二 UE根据上 行调度信息查找自身存储的上传数据方式确定的。
步骤 1003: 在接收第一 UE与第二 UE协同发送的 MAC PDU后， 基站 向第一 UE与第二 UE发送确认信息， 或者， 向第一 UE与第二 UE发送否 认信息， 以使第一 UE和 /或第二 UE根据否认信息重新发送 MAC PDU。
步骤 1004: 基站接收第一 UE和 /或第二 UE重新发送的 MAC PDU。 步骤 1001-1002与步骤 901-902类似， 此处不再贅述。 与方法实施例 7 相比， 本实施例在第一 UE与第二 UE协同发送的 MAC PDU后， 进一步包 括根据接收到的 MAC PDU , 向第一 UE以及第二 UE发送确认信息或否认 信息， 若两个 MAC PDU都需要重传时， 则按照初传方式， 即第一 UE和 第二 UE协同重传，若仅有一个 MAC PDU需要重传时，则生成该 MAC PDU 的 UE自己向基站 eNB重传该 MAC PDU。 与上述数据调度方法实施例 8 相对应的， 本发明实施例还提供一种上 行数据调度***实施例 3 , 包括基站 eNB、 第一 UE以及第二 UE。 结合图 12 所示的信令交互示意图， 对上述各个部分所起作用以及各部分间的信息交 互过程进行简单介绍。
步骤 1101 : 基站向第一用户设备 UE和第二 UE发送上行调度信息。 步骤 1102:第一 UE和 /或第二 UE根据上行调度信息生成需要发送的媒 体接入控制层协议数据单元 MAC PDU。
步骤 1103: 第一 UE 与第二 UE通过短距离无线通信方式共享 MAC PDU。
步骤 1104:第一 UE与第二 UE通过 MU-MIMO通信方式协同发送 MAC PDU, 基站接收第一 UE与第二 UE通过 MU-MIMO通信方式协同发送的 MAC PDU。
步骤 1105: 基站向第一 UE与第二 UE发送确认信息或者， 向第一 UE 与第二 UE发送否认信息。
步骤 1106: 若 MAC PDU需要重传， 第一 UE和 /或第二 UE根据否认 信息重新发送 MAC PDU,基站接收第一 UE和 /或第二 UE重新发送的 MAC PDU。
在传统的调度方法中， 基站向 UE发送调度信息后到基站收到 UE发送 的上行数据的间隔是 4ms, 但是， 本发明实施例需要考虑 MAC PDU在 UE 间通过短距离无线通信的时间， 假定两 UE共享 MAC PDU的延迟时间为 lms,则本发明实施例基站向 UE发送调度信息后，在 5ms后接收 MAC PDU。
需要注意的是，若假设基站向 UE发送上行调度信息的时刻为 N时刻， 当第一 UE和 /或第二 UE的上传数据方式为第一 UE与第二 UE协同上传数 据时，则基站接收第一 UE与第二 UE协同发送的 MAC PDU的时刻为 N+5 时刻， 那么基站需要避免在 N+1时刻调度第一 UE在 N+5时刻直接向基站 上传第一 UE自己的数据， 或在 N+1时刻调度第二 UE在 N+5时刻直接向 基站上传第二 UE 自己的数据。 同时， 具体的每一步骤发生时刻可以根据 实际情况进行设定， 图中仅仅给出的是一个示例， 本发明实施例对此不作 限定。

两 UE 均接收上行调度信息， 当数据发送提示信息提示需要发送的 MAC PDU的上传数据方式为第一 UE与第二 UE通过 MU-MIMO通信方式 协同上传数据时， 数据产生标识信息携带第一 UE 的身份信息 （例如上行 调度信息利用第一 UE的 C-RNTI加扰） 可以调度第一 UE生成需要发送的 两个 MAC PDU或数据产生标识信息携带第二 UE的身份信息 (例如上行 调度信息利用第二 UE的 C-RNTI加扰） 可以调度第二 UE生成需要发送的 两个 MAC PDU。 同时数据发送提示信息还可以包括另一 UE的 C-RNTI, 也可以包括预先配置的传输路径对应表， 表中包括与一 UE具有合成关系的 其他 UE的索引值。 需要注意的是， 当第一 UE仅与第二 UE具有合成关系 时，数据发送提示信息提示两 UE协同上传数据时， 代表一 UE已经获知与 哪个 UE 协同上传数据， 则数据发送提示信息可以不包括另一 UE 的 C-RNTL
另外， 数据发送提示信息还可以提示上传数据方式为自己向基站上传 数据， 则此时数据产生标识信息可以提示该 UE生成一个 MAC PDU。 该过 程与现有技术类似， 此处不再贅述。
