根据本发明, 本发明, 提出了一种对无线资源的动态调度机制, 其中集成 了无线资源效率、 调度公平和 MBSFN传输协调要求, 还考虑到了 MCE、 eNB和 UE (移 动台) 之间经由 M2和 Uu接口的相关信令交互。
需要解释的是, 根据本发明, 用于 eMBMS调度和 MBSFN传输的工作配置如下 所示: ' '
1 )将 MCE定义为用于 MBSFN传输的 MBSFN区域中的所有 eNB的无线资源分配的 逻辑功能实体, 并且还由 MCE来决定针对 MBSFN传输的无线电配置的进一步细节, 例如 MCS (调制编码方案)。 MCE是针对 MBSFN传输中所涉及的所有 eNB的中央协调 实体。
2 ) eMBMS调度是周期性的, 一个调度周期可以为诸如 320ms, 另外, 如已知 的, 可以釆用 TM (时分复用) 模式在混合载波中对 MBMS服务和单播进行复用。
3 ) 在每一个调度周期中, 确定被定义为能够执行 MBSFN传输的 MBSFN子帧的 分配信息, 这被称为 MSAP (MBMS子帧分配模式) 信息。 该 MSAP信息是半静态的且 由 MCE来确定。 该 MSAP信息确定了能够用于 MBSFN传输的 MBMS子帧分配的最大范 围。
4) 针对 MBMS服务的 MBSFN传输应该仅出现在经由系统信息 SIB2 ("系统信息 块类型 2 ") 的 MBSFN子帧分配模式所预先配置的 MBSFN子帧, 即 MSAP信息所指示的 MBSFN子帧范围。 应该排除一个无线帧中的 # 0、 # 4、 # 5和 # 9子帧来进行 MBSFN 子帧分配。 下面将参考附图来描述本发明的优选实施例。
图 1是根据本发明的对用于 MBMS的 MBSFN传输的无线资源进行动态调度的方 法的流程图。 .
如图 1所示, 根据本发明的对无线资源进行动态调度的方法, 在步骤 101, 针对当前调度周期, 根据用于 MBSFN传输的每个 MBMS服务或 MBMS服务组的服务质 量 (QoS)要求, 由 MCE确定针对每个 MBMS服务或 MBMS服务组的半静态 MBMS调度信 息。
这里, 需要指出的是, 可以将用于 MBSFN传输的 MBMS服务分为两种类型。一 种类型是统计复用服务; 另一种类型是非统计复用服务。 具有 BLER (块差错率) 的相同 QoS要求 (例如, 具有相同的调制编码方案) 的那些服务可以被复用为一 个 MAC PDU (介质接入控制-协议数据单元)。 这被称为统计复用。 复用到一个 MAC PDU中的所有服务被定义为一个服务组, 在确定 MSAP时, MCE可以该服务组看作 如同一个 "服务"来进行操作。 因此, "MBMS服务或 MBMS服务组" 中的 "MBMS服 务" 是指非统计复用服务, 而 "MBMS服务组" 是对具有相同块差错率的 QoS要求 的多个 MBMS服务进行统计复用形成的服务组。
根据针对每一个 MBMS服务或 MBMS服务组的 QoS要求, MCE所确定的半静态 ffiMS调度信息可以包括以下三种信息:
- 针对每一个 MBMS服务或 MBMS服务组的传输次序;
― MSAP信息; 以及
- 调制编码方案 (MCS ) 信息。 传输次序包括形成 MBMS服务组中的各个 MBMS服务的内部传输次序和在该 MBSFN区域中的所有 MBSFN传输服务次序。 对于所有 MBSFN传输服务次序, 可以将 一个统计复用服务组看作一个服务来进行排序。 例如, 存在表示为 Sl、 S2、 S3、 S4和 S5的五个 MBSFN传输服务, 其中 Sl、 S3和 S4是统计复用服务且属于一个服务 组 {Sl, S3 , S4}。 然后考虑形成 MBMS服务组中的各个 MBMS服务的诸如优先级或延 迟等 QoS要求, 该服务组的内部传输次序为 {S3, Sl, S4}, 并且对于所有 MBSFN传 输服务次序, 由 MCE所确定的最终传输次序将是 {S5 , {S3, Sl, S4} , S2}。
这里, 所述 MSAP信息指示针对每个薦 MS服务或 MBMS服务组的用于 MBSFN传输 的 MBSFN子帧分配的最大范围。 针对 MSAP信息, 也将一个统计复用服务组看作一 个服务来进行确定。 根据针对每一个 MBMS服务的 QoS要求, 例如, 针对非统计复 用服务的 GBR (保证比特速率) 或 MBR (最大比特速率) 和 BLER要求、 以及针对统 计复用服务组的 ABBR (聚合组比特速率) 和 BLER要求等, MCE可以确定 MCS信息和 MSAP信息。针对 MBMS服务或 MBMS服务组动¾调度的子帧将不会超过由 MSAP信息所 指示的 MBSFN子帧分配的子帧范围。 因此, 该 MSAP信息用来限制针对每一个 MBMS 服务或服务组的 MBSFN传输的子帧范围。 例如, 如果在一个调度周期的 MSAP中, 存在为一个 MBMS服务定义的三个子帧, 这意味着针对该 MBMS服务, 后续的动态调 度将不会超过三个子帧。 接下来, 在图 1的步骤 103, 由所述 MCE将所确定的半静态 MBMS调度信息通知 给 MBSFN区域内的每个基站和每个基站所控制的相应移动台。
转到图 2, 图 2是从 MCE经由 M2接口和 Uu接口向基站和基站所控制的相应移动 台通知半静态 MBMS调度信息的过程的时序图。
如图 2所示, 将上述半静态调度信息经过 MCE和 eNB之间的 M2接口从 MCE传输 到在 MBSFN区域中每个基站, 例如经由 MBMS调度信息。 该 eNB从 MCE接收该半静态 MBMS调度信息消息, 并且根据该半静态 MBMS调度信息消息中的详细内容来更新该 eNB的配置和相关的 RRC消息。 考虑到该通知和 MCCH (MBMS点对多点控制信道) 消 息周期传输机制, 每个基站经由不同 RRC (无线资源控制) 信令 (例如 MBMS修改 服务信息信令、 MBMS未修改服务信息信令和当前小区 PTM RB (点对多点无线承载) 信令) 将该半静态调度信息传输到相应的 UE。 之后, 所有所涉及的 eNB和这些 eNB 所控制的 UE将具有用来在基站 MAC层进行后续动态调度的相同的半静态 MBMS调度 信息。 这里, 需要强调的是, 在 MCE中进行了统一处理来协调针对所有基站的结 果。
根据本发明, 针对从 MCE到 eNB的该半静态 MBMS调度信息传递定义了在 M2接 口 (M2应用协议) 上的一个交互过程, 具体如图 3所示。 '
如图 3所示的该交互过程用于' 静态 MBMS调度信息传递, 可以被定义为
"MBMS调度信息过程", 用于传输 MSAP信息、 MCS信息和暗含在其中的传输次序。 该交互过程包括一对消息的传递, 即, MBMS调度信息消息和 MBMS调度信息响应消 息。 在该交互过程中, 使用确认模式来确保所有所涉及的 eNB能够正确地接收该 半静态调度信息。
如图 3所示, 从 MCE经过 M2接口向 eNB传送包括该半静态 MBMS调度信息的半静 态 MBMS调度信息消息。 e NB将 MBMS调度信息响应消息反馈到 MCE以指示该半静态 MBMS调度信息是否被正确接收。
图 4是根据本发明的从 MCE传送到基站的半静态 MBMS调度信息消息的示例消 息结构的示意图。
如图 4所示,在 MBMS调度信息消息中,针对每一个薦 MS服务(或 MBMS服务组), 存在包括其服务 ID、 MSAP信息、 MCS信息的信息组。 这些信息组的排列次序暗示 了这些 MBMS服务或 MBMS服务组的传输次序。 该统计复用服务组将被看作如同一个 服务。针对该 MBMS服务组定义统一的 MCS和 MSAP。在该 MBMS服务组中, 每一个 MBMS 服务具有内部传输次序, 该内部传输次序由 MCE根据 MBMS服务组内的每一个 MBMS 服务的优先级或延迟等 QoS要求来确定。
该 MBSFN子帧分配可以是一个调度周期内的离散分配, 但是数量和准确位置 是确定的。 由此, 图 4所示的 MBSFN子帧的索引可以将每一个 MBMS服务的子帧索引 的起始点用作 MSAP指示。 回到图 1, 在步骤 105, 每个 eNB根据从该 MCE所接收到的半静态 MBMS调度信 息和针对每个 MBMS服务或 MBMS服务组的要处理的实际数据量, 对无线资源进行 MAC层的动态调度。
具体地, 在该步骤 105中, 每一个 6NB MAC层将根据等待当前调度周期的每 一个 MBMS服务或服务组的实际处理薮据量来执行动态调度。 针对 MSAP中的每个 MBMS服务或服务组的子帧会基于 QoS要求, 但是实际的服务数据可以是突发的, 每一个周期的处理量也将是可变的。为了无线资源的最大利用和每一个服务的公 平处理, 这里提出了在 MSAP内的动态调度。 在一个调度周期中, 一个 MBMS服务或 服务组的最大子帧使用不可以超过针对该 MBMS服务或服务组的 MSAP信息所指定 的子帧分配。 在该动态调度过程中, 如果针对每个 MBMS服务或 MBMS服务组的要处 理的实际数据量未完全占用所述 MSAP信息所指示的针对所述 MBMS服务或 MBMS服 务组已分配的所有 MBSFN子帧, 则将未占用的 MBSFN子帧用于单播服务。 如果针对 每个 MBMS服务或 MBMS服务组的要处理的实际数据量无法完全充满所述 MSAP信息 所指示的针对所述 MBMS服务或 MBMS服务组已分配的 MBSFN子帧, 则仅在针对所述 MBMS服务的最后一个 MBSFN子帧中添加填充数据, 或者仅在形成所述 MBMS服务组 的所有 MBMS服务中的最后一个 MBMS服务的最后一个 MBSFN子帧中添加填充数据。
由于内容同步机制是可以确保所涉及的 eNB将面对具有相同量的相同内容 数据的 MBSFN传输的强制机制, 不同的 eNB可以根据相同的规则来获得一致的动态 调度结果。 根据本发明的动态调度不将影响 MBSFN传输的同步要求。
附带地, 应该将 eNB的 MAC层的动态调度结果即时地通知给 UE。 在每一个调 度周期中, 可以利用第一服务数据传输通过频带内的 MAC控制元件来传递该动态 调度结果, 该 MAC控制元件是一种新型的 M'AC控制元件, 被称为 " MBMS调度信息 MAC 控制元件"。 为了确保鲁棒性和 UE中的正确接收, 在调度周期期间可以考虑采用 重复机制。 针对每一个 MBMS服务或服务组 '的实际调度结果, 针对每一个 MBMS服务 或服务组应该仅列出 MBSFN子帧的结束索引。 由此, 在接收到该 " MBMS调度信息 MAC控制元件" 并结合先前接收到的半静态 MBMS调度信息时, UE可以明确且正确 地接收并解码其期望的 MBMS服务。
根据本发明的动态调度机制的优点在于. -
1 ) 可以满足每一个服务的 QoS要求;
2 ) 可以更有效地使用无线资源;
3 ) 可以考虑针对每一个服务的处理的公平性; 以及
4 ) 不会影响 MBSFN传输的同步要求。 图 5是根据本发明的对用于 MBMS的 MBSFN传输的无线资源进行动态调度的'操 作示例的示意图。
作为示例, 如图 5所示, 存在 5个参与 MBSFN传输的 MBMS服务, 具有服务 ID : Sl、 S2、 S3、 S4和 S5。 根据其 QoS要求, Sl、 S3和 S5具有相同的 BLER要求, 因此 其可以使用相同的 MCS, 并且复用为一个 MAC PDU。 由此, 存在一个用于复用的服 务组 {Sl, S3, S5}。 该服务组由服务器决定, 并且在会话幵始消息内将该决定通 知给 MCE。
然后, 根据本发明, 由 MCE确定半静态 MBMS调度信息, 例如针对每个 MBMS服 务或服务组的传输次序、 MSAP信息和 MCS信息。
在该示例中, 在 SIB2中的 MBSFN子帧分配是 "分配周期 = 8个无线帧", "偏 移 = 0 ", "子帧分配 = 111000 "。 于是, 在一个调度周期内包含 MBSFN子帧的该无 线帧索引被确定为 # 0、 # 8、 # 16和 # 24。 在这些无线帧中, 针对 MBSFN子帧的 子帧索引也被确定为 # 1、 # 2和 # 3。 在一个调度周期中的 MBSFN子帧的总数为 12 个, 具体如图 5所示。
由 MCE确定这些服务的 MSAP。 在该示例中, 针对服务组 {S3, SI , S5}为 7个 子帧; 针对 S4为 3个子帧, 而针对 S2为 2个子帧。
MCE还根据其诸如优先级、 延迟等 QoS要求, 确定这些服务或服务组的传输 次序。 例如, 这里的传输次序为 {S3, Sl, S5}、 S4、 S2, 其中服务组被看作如同 一个服务, 但是在服务组中, 这些 MBMS服务之间存在自身的内部次序。
还针对每一个 MBMS服务或服务组确定 MCS方案, 其中针对服务组 {S3, S 1 , S5}为 MCS1 ; 针对 S4为 MCS2 , 而针对 S2为! S3。
然后, 由 MCE中产生包含该半静态 MBMS调度信息的半静态 MBMS调度信息消 息, 并且通过 M2接口利用 "腿 MS调度信息过程" 将该半静态 MBMS调度信息消息 传送到 eNB。 eNB然后通过 Liu接口利用 RRC信令 (包括 MBMS修改服务信息、 MBMS未 修改服务信息和当前小区 PTM RB信息) 将该半静态 MBMS调度信息传送到 UE。
最后, eNB根据在该调度周期中处理的实际数据量来执行 MAC层的动态调度。 例如, 对于 MBMS服务组, S3占用 2. 5个子帧, S 1占用 1. 3个子帧, 而 S5占用 2. 5个 子帧; 对于 MBMS服务, S4占用 1. 6个子帧; 而 S2占用 2个子帧。 对于每一个 MBMS服 务或服务组, 可以仅在该 MBMS服务或服务组的最后一个子帧中添加填充数据。 例 如, 针对 MBMS服务组的填充数据可以添加到 S5的最后一个子帧, 而针对服务 S4的 填充数据可以添加到该服务 S4的最后一个子帧。 然后, 针对这五个服务的实际动 态调度结果将会是针对每一个 MBMS服务的 MBSFN子帧的结束位置索引, 针对 S3为 3 , 针对 S1为 4, 针对 S5为 6, 针对 S4为 9, 而针对 S2为 12。 图 5示出了这一情况。 因此在 MSAP信息中指示了该起始点子帧索引, UE可以使用该起始点子帧索 引和 MBSFN子帧的结束位置索引来获得针对每一个 MBMS服务确定的子帧占用。 图 6是根据本发明的实现对用于 MBMS的 MBSFN传输的无线资源进行动态调度 的 MCE的结构方框图。
如图 6所示, 根据本发明的 MCE包括: 调度信息确定装置 601、 调度信息传输 装置 603和反馈接收装置 605。 调度信息确定装置 601针对当前调度周期, 根据用 于 MBSFN传输的每个 MBMS服务或 MBMS服务组的 QoS要求, 确定针对每个 MBMS服务或 MBMS服务组的半静态 MBMS调度信息, 其中所述 MBMS服务组是对具有相同 BLER的 QoS要求的多个 MBMS服务进行统计复用形成的服务组。 调度信息传输装置 603将包 括该半静态 MBMS调度信息的半静态 MBMS调度信息消息传送给 MBSFN区域内的每个 eNB ; 以及反馈接收装置, 用于接收从每个 eNB所反馈的半静态 MBMS调度信息响应 消息, 以确认向基站传送的半静态 MBMS调度信息消息是否被正确接收。 图 7是根据本发明的实现对用于 MBMS的 MBSFN传输的无线资源进行动态调度 的基站的结构方框图。
如图 7所示, 根据本发明的 eNB包括: 调度信息接收装置 701、 动态调度装置 703、 调度信息传送装置 705和反馈装置 707。 调度信息接收装置 701从 MCE接收半 静态 MBMS调度信息消息, 该半静态 MBMS调度信息消息包括由 MCE根据用于 MBSFN传 输的每个 MBMS服务或 MBMS服务组的服务质查 QoS要求所确定的针对每个 MBMS服务 或 MBMS服务组的半静态 MBMS调度信息。'动态调度装置 703针对当前调度周期, 根 据所接收到的半静态 MBMS调度信息消息中所包括的半静态 MBMS调度信息、 以及针 对每个 MBMS服务或 MBMS服务组的要处理的'实际数据量, 对无线资源进行动态调 度。 调度信息传送装置 705通过无线资源控制 RRC信令向 UE传送所接收到的半静态 MBMS调度信息。 反馈装置 707, 用于向 MCE反馈半静态 MBMS调度信息响应消息, 以 指示该半静态 MBMS调度信息消息是否被正确接收。 尽管以上已经结合本发明的优选实施例示出了本发明, 但是本领域的技术 人员将会理解, 在不脱离本发明的精神和范围的情况下, 可以对本发明进行各种 修改、 替换和改变。 因此, 本发明不应由上述实施例来限定, 而应由所附权利要 求及其等价物来限定。
