在第三代合作伙伴计划 (3GPP, 3rd Generation Partnership Project )长期 演进(LITE, Long Time Evolution ) Release9版本中, 增强型多媒体广播多播 务 ( eMBMS, enhanced Multimedia Broadcast Multicast Service )可以通过多 小区方式、 即所谓单频网多播广播( MBSFN, Multicast/Broadcast over Single Frequency Network )方式进行传输, 这样相同的数据将在多个小区内采用相 同的调制编码方式、 在相同的物理资源上同时发送, 终端可以将在不同小区 中收到的信号进行合并, 其传输的帧结构如图 1所示。 支持 eMBMS业务的终 端在中继节点可以从多个小区接收相同的 eMBMS业务, 且接收到的多个 eMBMS业务不会相互干扰。
在 LTE ReleaselO版本中, 中继节点 (RN, Relay Node )被作为扩大系统 覆盖范围、 提高系统容量的重要手段而引入网络。 RN在 ReleaselO网络中类似 于一个基站, 有自身独立的物理小区标识(Physical Cell id ), 因此其网络部署 场景类似于微小区 (pico cell ), 具体网络结构示意图如图 2所示。
现有技术中, RN以单播方式与其下属的终端进行通信, 如果 RN不支持 MBSFN传输, 而在图 1所示的 MBSFN子帧结构中发送单播数据, 那么支持 eMBMS业务的终端将在中继节点下接收到中继节点发送的单播数据, 而无法 接收对应的 eMBMS业务数据, 并且所接收的单播业务由于受到其他小区发送 的 eMBMS业务的影响也会受到极大地千扰。
此外, MBMS业务控制信道(MCCH, MBMS Control Channel )是 LTE MBMS系统中一种点到多点的下行信道, 用于传送网络侧到用户终端 (UE, User Equipment )侧的控制信息。 网络侧在广播控制信道(BCCH, Broadcast Control Channel ) 中向 UE指示 MCCH的位置信息, 从而使得用户终端能按照 指示的位置读取 MCCH上传送的信息。

无线资源分配相关信息: 指一种或多种 MBMS业务描述所服务的小区中 使用的无线资源信息。 对于每种业务, 可能包括业务占用的物理信道信息, 传输信道信息等, 以及其它信息。
当 MCCH携带的信息发生变化时, 如 MBMS的业务发生改变, 会话或者 无线承栽信息等发生变化时, 网络侧需要通知用户终端; 即网络侧需要向用 户终端发送 MCCH修改通知; 用户终端在接收到 MCCH修改通知之后,会去侦 听 MCCH获取发生变化后的新信息。

下面将结合本发明的实施例中的附图, 对本发明的实施例中的技术方案 进行清楚、 完整地描述, 显然, 下面所描迷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的前提下所获得的所有其他实施例, 都属于本发明的 实施例保护的范围。
本发明实施例的核心思想是: 中继节点将与 eMBMS业务相关的 MBSFN 子帧静默, 从而避免对用户终端接收 eMBMS业务的影响。
本发明实施例一提供一种中继网络中支持增强的多媒体广播多播 eMBMS业务的方法, 如图 3所示, 包括:
步骤 301 , 网络侧向中继节点发送用以指示与 eMBMS业务相关的单频网 多播广播 MBSFN子帧在传输帧中的位置的消息。
较佳地, 该指示消息可以通过网络侧与中继节点之间预先配置的专用信 令来实现。
步骤 302,所述中继节点 居接收到的指示消息,确定所述 MBSFN子帧在 传输帧中的位置, 并根据确定的位置静默所述 MBSFN子帧。 其中中继节点可 以采用下述任意方式之一静默所述 MBSFN子帧:
所述中继节点将所述 MBSFN子帧设置为空白子帧; 或者
所述中继节点将所述 MBSFN子帧设置为空白 MBSFN子帧; 或者
所述中继节点在所述 MBSFN子帧中携带对应的增强的多媒体广播多播业 务的控制信息。
具体地, 空白 MBSFN子帧可以全部用于传输 PDCCII控制信令, 空白子帧 可以全部用于传输 PDCCH控制信令以及导频, 或者空白子帧也可以不传输任 何信息。
步骤 303, 所述用户终端在确认出中继节点发送的传输帧中存在被该中继 节点静默的 MBSFN子帧时,根据接收到的 eMBMS业务的控制信息接收所述中 继节点之外的设备发送的 eMBMS业务。
若所述中继节点将所述 MBSFN子帧设置为空白子帧, 则所述用户终端接 收该中继节点之外的设备(例如增强型基站(eNB, enhanced Node-B ) )发送 的 eMBMS业务的控制信息, 并根据该控制信息获取 eMBMS业务的数据信息。
若所述中继节点转发 eMBMS业务的控制信息, 则所述用户终端 居该中 继节点转发的 eMBMS业务的控制信息接收该中继节点之外的设备发送的 eMBMS业务的数据信息。
若所述中继节点转发 eMBMS业务的部分控制信息,即 eMBMS业务的系统 信息, 则所述用户终端根据该系统信息、 并获取该中继节点之外的设备发送 的 eMBMS业务的多播控制信道信息, 合并上述接收到的系统信息和多播控制 信道信息得到所述 eMBMS业务的控制信息, 根据该得到的控制信息接收中继 节点之外的设备发送的 eMBMS业务的数据信息。 本发明实施例二提供一种中继网络中支持增强的多媒体广播多播 eMBMS业务的方法。
其中, 如果 RN的回传链路没有问题,则相应的控制面接口 M2与用户面接 口 Ml接口可以延伸到 RN, 并且通过部分沿用的方式进行 eMBMS业务传输, 如图 4和图 5所示。其中图 4所示的中继架构中包括 Relay-UE's 移动性管理实体 ( MME, Mobility Management Entity ), User-UE's多用户边缘设备(MCIi, Mutiple Custom Edge ) 基站 Donor-eNB以及中继节点等设备, 其中 RN具有相 当于一个增强型基站( eNB, enhanced Node-B )的功能,可以直接与 Donor-eNB (基站) 交互 eMBMS业务信息, 并向用户终端发送 eMBMS数据业务。 图 5所 示的中继架构中包括 MCE、 MME. Donor-eNB以及 RN等, 其中 RN可以直接 转发收到的 eMBMS业务。
本发明实施例提供的方法重点关注 RN的回传链路有问题的情况, 即 RN 无法转发 eMBMS业务的情况。 如图 6所示, 该方法包括以下步骤:
步骤 601 ,网络侧向 RN发送用以指示与 eMBMS业务相关的 MBSFN子帧在 传输帧中的位置的消息。
具体的, 本发明实施例中, 网络侧 (例如基站) 与 RN之间配置专用信令 用于传输用以指示与 eMBMS业务相关的 MBSFN子帧在传输帧中的位置的消 息。 网络侧向 RN发送与 eMBMS业务相关的消息时, 通过专用信令向 RN发送 用以指示与 eMBMS业务相关的 MBSFN子帧在传输帧中的位置的消息。该专用 信令中还可以携带 eMBMS业务的控制信息, 例如 eMBMS业务的数据信息在 MBSFN子帧中具体的发送位置等。
步骤 602, RN根据接收到的消息, 确定 MBSFN子帧在传输帧中的位置, 并根据确定的位置信息将 MBSFN子帧静默, 以及通过传输帧中的其他位置向 用户终端发送 eMBMS业务消息。
具体的, RN可以通过专用信令获取 MBSFN子帧在传输帧中的位置, 然后 将该位置的子帧设置为空白子帧、 或者设置为空白 MBSFN子帧。 如果为空白 子帧, 则用户终端将无法从该子帧获得任何信息, 从而不会影响到用户终端 从其他设备获取 eMBMS业务。如果为空白 MBSFN子帧,用户终端获知该子帧 为传输 eMBMS业务信息的子帧,但是无法从该空白 MBSFN子帧中获取任何信 息。
如果 RN可以从网络侧获取到 eMBMS业务相关的系统信息, 则 RN还可以 在 MBSFN子帧中向用户终端传输该 eMBMS业务相关的系统信息。用户终端获 取到该 eMBMS业务相关的系统信息后,进一步从 RN之外的设备(例如基站设 备)获取该 eMBMS业务相关的多播控制信道信息,将 eMBMS业务相关的系统 信息与多播控制信道信息合并得到 eMBMS业务的控制信息, 并根据合并得到 的该控制信息接收 RN之外的设备发送的 eMBMS业务的数据信息。
如果 RN可以从网络侧获取到 eMBMS业务的控制信息, 则 RN可以在 MBSFN子帧中向用户终端传输该 eMBMS业务的控制信息。 用户终端接收到 eMBMS业务的控制信息后, 直接根据该控制信息接收 RN之外的设备发送的 eMBMS业务的数据信息。
步骤 603, 用户终端在确认出中继节点发送的传输帧中存在被该中继节点 静默的 MBSFN子帧时, 从 RN以外的设备接收 eMBMS业务。
具体的, 该用户终端为 RN下属的用户终端。
若 RN向用户终端发送的传输帧中携带 MBSFN子帧的位置为空白子帧或 者为空白 MBSFN子帧,则用户终端从该位置子帧将得不到任何与接收 eMBMS 业务相关的信息。 此时, 用户终端可以从 RN以外的 eNB等设备接收到 eMBMS 业务的控制信息和数据信息, 由于 RN发送的传输帧中 MBSFN子帧为空, 因而 不会影响用户终端接收 eNB等设备发送的 eMBMS业务信息, 用户终端可以实 现正常接收 eMBMS业务信息。
若 RN在 MBSFN子帧中携带 eMBMS业务的控制信息, 则用户终端可以根 据该控制信息监听 eNB等设备发送的 eMBMS业务的数据信息。 ' 若 RN在 MBSFN子帧中携带 eMBMS业务相关的系统信息, 则用户终端根 据该系统信息可以进一步接收其他设备(eNB等设备)发送的 eMBMS业务相 关的多播控制信道信息, 将 eMBMS业务相关的系统信息与多播控制信道信息 合并得到 eMBMS业务的控制信息,进一步根据该 eMBMS业务的控制信息监听 eNB等设备发送的 cMBMS业务的数据信息。 这种情况下, 如果 RN也可以接收 cNB等设备发送的 eMBMS业务的控制信息, 由于 RN和 eNB等设备发送的 eMBMS业务的控制信息相同, 因此也不会相互影响,且合并后提高了 eMBMS 业务的控制信息的信号强度, 更有利于用户终端高效接收 eMBMS业务的控制 信息, 并根据该 eMBMS业务的控制信息进一步接收 eMBMS业务的数据信息。
更进一步地, 在本发明实施例中, 为了保证用户终端能够接收到 eMBMS 业务的多播控制信道(MCCH, Multicast Control Channel )信息, 网络侧(例 如 eNB )还可以向 RN发送 MCCH配置信息 (包括 MCCII的发送位置和 /或重复 周期等), 再由 RN向用户终端转发该 MCCH配置信息, 用户终端根据 MCCII 配置信息接收 eMBMS业务的 MCCH信息。 其中, 网络侧可以通过专用控制信 令向 RN发送 MCCH配置信息。 RN可以通过专用控制信令或者系统广播消息向 用户终端发送上述配置信息。
通过采用本发明实施例提供的上述方案, 网络侧通知中继节点与 eMBMS业务 相关的 MBSFN子帧在传输帧中的位置信息, 中继节点 居该通知的位置信息 将 MBSFN子帧静默并将传输帧向用户终端发送, 使用户终端接收中继节点之 外的设备发送的 eMBMS业务,从而避免了中继节点对支持 eMBMS业务的用户 终端的影响, 使用户终端可以顺利接收 eMBMS业务。

所述接收单元 21可以具体通过接收网络侧通过专用控制信令发送 MCCI-I 配置信息。
所述发送单元 24可以具体通过专用控制信令或者系统广播消息向所述用 户终端发送所述 MCCH配置信息。
其中所述 MCCH配置信息中可以但不限于包括 MCCH的发送位置和 /或重 复周期。 本发明实施例五提供一种基站设备, 如图 9所示, 包括:
确定单元 31,用于确定与 eMBMS业务相关的 MBSFN子帧在传输帧中的位 置信息;
发送单元 32, 用于根据确定的位置信息, 向中继节点发送用以指示与 eMBMS业务相关的 MBSFN子帧在传输帧中的位置的消息。具体地,发送单元 32具体可以通过配置的专用信令, 向中继节点发送用以指示与 eMBMS业务相 关的 MBSFN子帧在传输帧中的位置的消息。
本发明实施例六提供一种用户终端, 如图 10所示, 包括:
确认单元 41, 用于确认中继节点发送的传输帧中是否存在被所述中继节 点静默的 MBSFN子帧;
接收单元 42, 用于在确认存在时, 根据接收到的 eMBMS业务的控制信息 接收所述中继节点之外的设备发送的 eMBMS业务。
所述接收单元 42具体可以用于接收所述中继节点发送的 eMBMS业务的 系统信息、 以及接收所述中继节点之外的设备发送的 eMBMS业务的多播控制 信道信息, 合并得到 eMBMS业务的控制信息; 并根据合并得到的该 eMBMS 业务的控制信息获取所述中继节点之外的设备发送的 eMBMS业务的数据信 所述接收单元 42具体也可以用于接收所述中继节点传输的 eMBMS业务 的控制信息, 并根据所述控制信息直接获取所述中继节点之外的设备发送的 eMBMS业务的数据信息。
所述接收单元 42具体还可以用于接收所述中继节点之外的设备发送的 eMBMS业务的控制信息, 并根据所述控制信息直接获取所述中继节点之外的 设备发送的 eMBMS业务的数据信息。
通过采用本发明实施例提供的方法、 系统和设备, 网络侧通知中继节点 与 eMBMS业务相关的 MBSFN子帧在传输帧中的位置, 中继节点将 MBSFN子 帧静默并将传输帧向用户终端发送, 使用户终端接收中继节点之外的设备发 送的 eMBMS业务, 从而避免了中继节点对支持 eMBMS业务的用户终端的影 响, 使用户终端可以顺利接收 eMBMS业务。
此外, 本发明实施例七提供一种中继网络中支持增强的多媒体广播多播 eMBMS业务的方法, 如图 11所示, 包括:
步骤 1001, 网络侧向中继节点发送 MCCH配置信息。
所述网络侧可以通过专用控制信令向中继节点发送 MCCH配置信息 (包 括 MCCII的发送位置和 /或重复周期等)。 该控制信令可以是 RRC层信令(例如 RRC重配置信令), 也可以是其他专用控制信令(例如 MAC层信令等)。 特别 的, 配置信息可以是 LTE R9系统中的 mcch-Config-r9消息中的部分或全部信 台
步骤 1002, 所述中继节点接收 MCCH配置信息并向用户终端发送。
所述中继节点可以通过专用控制信令(例如 RRC重配置信令)或者系统 广播消息 (例如 SIB13 ) 向所述用户终端发送 MCCII配置信息。
其中, 中继节点在接收到 MCCH配置信息后还可以向网络侧发送确认接 收信息, 同理用户终端在接收到 MCCH配置信息后还可以向中继节点发送确 认接收信息。
通过采用本发明实施例提供的该方案, 网络侧向中继节点发送 MCCH配 置信息, 并由中继节点转发给用户终端, 用户终端根据该 MCCH配置信息就 可以知道 MCCH的位置信息以及相关配置参数,从而可以根据 MCCH配置信息 准确接收 eMBMS业务的 MCCH信息。 当网络侧改变了 MCCH的位置或者某些 参数(例如 MCS )后, 用户终端可以及时获取新的 MCCH的位置, 从而可以 准确地接收 eMBMS业务, 不影响用户终端的 eMBMS业务的功能。
基于与实施例七相同的技术构思, 本发明实施例八提供一种中继网络中 支持增强的多媒体广播多播 eMBMS业务的系统, 包括网络侧设备、 中继节点 与用户终端, 其中
所述网络侧设备, 用于向中继节点发送 MCCH的配置信息;
所述中继节点, 用于接收所述 MCCH配置信息并向用户终端发送。 基于与实施例七相同的技术构思, 本发明实施例九提供一种中继节点, 包括:
接收单元, 用于接收网络侧发送的 MCCH配置信息;
发送单元, 用于向用户终端发送所述 MCCH配置信息。
所述接收单元具体通过接收网络侧通过专用控制信令发送的 MCCH配置 信息。
所述发送单元具体通过专用控制信令或者系统广播消息向所述用户终端 发送所述 MCCH配置信息。
其中所述发送配置信息包括所述 MCCH的发送位置和 /或重复周期等。 通过采用本发明实施例提供的上述系统和中继节点, 网络侧向中继节点 发送 MCCH配置信息, 由中继节点进而转发给用户终端, 从而可以使用户终 端根据所述 MCCH配置信息在 MCCH的发送位置和时间准确接收 eMBMS业务 的 MCCH信息。 另一方面, 当 RN引入 LTE系统中后, 对于与 MBMS相关的通知信令传输, 存在以下需求:
针对 RN支持 MBMS传输的情况, RN应及时将与 MBMS传输相关的 MCCH 修改通知信息及时通知到 UE, 从而使得 UE及时去接收 MCCH的更新内容, 从 而保证 UE对 MBMS业务相关信息的接收;
针对 RN不支持 MBMS传输的情况, 仍然需要通过 MBSFN传输网络的特 点, 使得 UE可以接收到其他小区的 MBMS业务的传输信息, 因此, 需要制定 信令传输机制使得 UE能够及时知道网络侧 MCCH的变更通知。
为了满足以上中继网络中对发送 MCCH修改通知信息的需求, 本发明实 施例提供了相应的解决方案, 其中:
针对 RN支持 MBMS传输的情况, 本发明实施例通过由 RN在规定的发送 MCCH修改通知信息发送时间之前, 从 DeNB得到 MCCH修改通知发送配置信 息及其 MCCII修改通知信息, 并将 MCCH修改通知发送配置信息通知给 U:, 当 MCCI 改通知信息的发送时间达到时, IIN与 DeNB采用 MBSFN方式同步 发送 MCCH i 改通知信息。 其中所述的 MCCH修改通知发送配置信息, 包括: 所述 MCCH修改通知信息所对应的发送位置信息, 相关参数有: 发送 MCCII 修改通知的重复次数, 发送通知信息的偏移量, 以及具体发送通知信息的子 帧。 以下通过实施例一对该解决方案的具体实现进行详细描述。
针对 RN不支持 MBMS传输的情况,本发明实施例通过 RN在下一个 MCCII 修改边界之前从 DeNB得到 MCCH修改通知信息, 然后通过下行控制信令将获 得的 MCCII修改通知信息发送给 UE。 以下通过实施例二和实施例三对该解决 方案的具体实现进行详细描述。
本发明实施例中所述的 MCCH修改通知发送配置信息可以用于指示 MCCII修改通知信息的具体的发送位置, 还可包括 UE和 /或 RN在一个 MCCI I 修改周期内没有成功检测到 MCCH修改通知信息时尝试接收该通知信息的最 小次数, 用于指示 U在下一个 MCCH修改边界去读取更新的 MCCH内容, 包 括 MBMS业务信息、 无线资源分配等相关信息; MCCH修改通知信息可用于 指示 UE是哪个 MBSFN区域对应的 MCCH发生了变化。
下面将结合本发明中的附图, 对本发明中的技术方案进行清楚、 完整的 描述, 显然, 所描述的实施例是本发明的一部分实施例, 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的 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。
实施例十
本实施例所涉及的网络架构可如上述图 12所示, 包括主控基站 (DeNB ) 和 RN,其中 RN支持 MBMS传输。针对这种情况,本实施例中 RN可提前从 DeNB 接收 MCCH修改通知发送配置信息以及 MCCH修改通知信息, 并可将 MCCH 修改通知发送配置信息发送给 UE。当 DeNB规定的 MCCH修改通知信息发送时 间到达时, RN与基站同步发送 MCCH修改通知信息, 从而保证 UE能够根据该 MCCII修改通知信息,在下一个 MCCH修改边界去读取更新的 MCCH内容, 包 括 MBMS业务信息和无线资源分配相关信息等信息, 以便正确接收 MBMS业 务。
如图 13所示, 本发明实施例的流程可以包括:
步骤 201、 RN从 DeN 接收 MCCH修改通知发送配置信息。
该步骤中, DeNB可根据系统约定发送下行控制信息, 其中携带 MCCII修 改通知发送配置信息,这样, RN可通过监听、接收下行控制信息,获得 MCCII 修改通知发送配置信息。 其中, DeNB发送该配置信息以及 RN接收该配置信 息的时间可由系统指定, 或者由规范规定。 系统或规范制定的 MCCH修改通 知发送配置信息的发送时间应该能够保证 RN或 UK在接收到 MCCH修改通知 信息之前接收到该 MCCH修改通知发送配置信息。
步骤 202、 RN将 MCCH修改通知发送配置信息发送给 UE。
该步骤中, RN可将 MCCH修改通知发送配置信息承载于下行控制信令发 送给 UB。 该下行控制信令可以是 PDCCH ( Physical Downlink Control Channel, 物理下行控制信道)信令, 也可以是 MAC ( Media Access Control, 媒体访问 控制 )层信令, 还可以是 RRC ( Radio Resource Control, 无线资源控制)层信 令, 或是其他能够承载 MCCH修改通知信息的控制信令。
步骤 203、 RN从 DeNB接收 MCCH修改通知信息。
该步骤中, RN接收 MCCH修改通知信息的时间可由系统指定, 或者由规 范规定。
步骤 204、 RN在 DeNB规定的 MCCH修改通知信息的发送时间发送 MCCI I 修改通知信息。
由于 RN是在 DeNB规定的 MCCH修改通知信息的发送时间发送 MCCII修 改通知信息, 在该时间, DeNB也要发送 MCCH修改通知信息, 且有机制保证 RN或 UE能够在 MCCH修改边界到达之前接收到该通知信息, 因此, RN和 DeNB会同步发送 MCCH修改通知信息,也就能够保证 UE在 MCCH修改边界到 达之前接收到 RN发送的该通知信息。
当 UB根据接收到的 MCCH修改通知发送配置信息接收到 MCCII修改通知 信息后, 在下一个 MCCH修改边界去读取更新的 MCCH内容, 包括修改后的 cMBMS业务信息和无线资源分配相关信息等信息, 从而可以根据修改后的 cMBMS业务信息和无线资源分配相关信息接收 MBMS业务。
上述流程中, DeNB在发送 MCCH修改通知发送配置信息和 MCCH修改通 知信息的时序上, 一般来说, 由于 MCCH修改通知发送配置信息属于半静态 信息, 而 MCCH修改通知信息每个周期可能变化, 因此先发送 MCCII修改通知 发送配置信息, 再发生 MCCH修改通知信息。
上述流程中, 由于 RN支持 MBMS传输, 因此, RN能够通过基站的下行控 制信令接收基站发送的 MCCH修改通知信息, 以及将其发送给 UE。 具体的, DeNB可以将 MCCH修改通知信息承载于下行控制信令(如 PDCCH信令)发送 给 RN, RN也可以将 MCCH修改通知信息承载于 RN对 UE的下行控制信令(如 PDCCH信令)发送给 UE。
基于相同的技术构思, 本发明实施例还提供了一种 RN设备。
如图 14所示, 该 RN设备可以包括: 第二接收模块 301、 第二发送模块 302、 第一接收模块 303、 第一发送模块 304, 其中:
第二接收模块 301, 用于从基站接收 MCCH修改通知发送配置信息; 该模 块可通过接收基站发送的下行控制信令, 接收其中携带的 MCCH修改通知发 送配置信息;
第二发送模块 302, 用于将第二接收模块 301接收到的 MCCH修改通知发 送配置信息发送给用户设备; 该模块可通过下行控制信令发送所述 MCCH修 改通知发送配置信息;
第一接收模块 303, 用于从基站接收 MCCH修改通知信息;
第一发送模块 304, 用于将第一接收模块 303接收到的 MCCH修改通知发 送配置信息发送给用户设备。 该模块可在与基站发送所述 MCCH修改通知信 息相同的时间发送所述 MCCH修改通知信息,即与基站同步发送 MCCH修改通 知信息。
第二接收模块 301可根据系统指定的或规范规定的时间, 从基站接收所述 MCCII修改通知发送配置信息; 第一接收模块 303可根据系统指定的或规范规 定的时间, 从基站接收所述 MCCH修改通知信息。
第一接收模块 303在接收 MCCH修改通知信息时, 可通过接收基站发送的 承载有所述 MCCH修改通知信息的下行控制信令,接收所述 MCCH修改通知信 息;第一发送模块 304可将所述 MCCH修改通知信息承载于 PDCCH信令发送给 用户设备。
通过以上描述可以看出,针对 RN支持 MBMS传输的情况, 通过 RN在规定 的 MCCH修改通知信息发送时间之前获取 MCCH修改通知信息以及通知发送 配置信息, 并将通知发送配置信息发送给 UE, 这样, 当 DeNB规定的 MCCII 修改通知信息的发送时间到达时, RN与 DeNB采用 MBSFN传输方式同步发送 MCCII修改通知信息, 从而使 UE能够根据该 MCCH修改通知信息, 在下一个 MCCII修改边界去读取更新的 MCCH内容,包括 MBMS业务信息和无线资源分 配相关信息。可见, 居以上描述, RN可以及时将与 MBMS传输相关的 MCCII 修改通知信息发送到 UE, 从而使得 UE及时去接收 MCCII的更新内容, 从而保 证 UH对 MBMS业务相关信息的接收。
实施例十一
本实施例所涉及的网络架构可如上述图 12所示, 包括主控基站 (DeNB ) 和 RN,其中, RN不支持 MBMS传输。针对这种情况,本实施例中 RN可在 MCCH 修改边界之前, 从 DeNB接收 MCCH修通通知信息并在 MCCH修改边界之前, 将其发送给 UE, 从而保证 UE能够及时接收 MCCH修改通知信息, 以便在下一 个 MCCH修改边界去读取更新的 MCCH内容,包括 MBMS业务信息和无线资源 分配相关信息。
如图 15所示, 本发明实施例的流程可以包括:
步骤 401、 RN从 DeNB接收 MCCH修改通知信息。 可选的, RN在接收到 MCCI I修改通知信息后, 可向 DeNB返回确认信息。
该步骤中, DeNB可以将 MCCH修改通知信息承载于下行控制信令发送给 RN。 该下行控制信令可以是专用控制信令或者公共控制信令, 信令承栽的方 式可以是 PDCCH信令, 也可以是 MAC层信令, 还可以是 RRC层信令, 或是其 他能够承载 MCCH修改通知信息的控制信令。
步骤 402、 RN在 MCCH修改边界之前(即当前 MCCH修改周期结束之前, 也即下一个 MCCH修改周期开始之前), 将在此之前从 DeNB接收到的 MCCH 修改通知信息发送给 UE, 使 UE可以不必在 DeNB规定的 MCCH修改通知信息 发送时刻去接收该通知信息。
该步骤中, RN可以将 MCCH修改通知信息承载于下行控制信令发送给 UE。 该下行控制信令可以是专用控制信令或者公共控制信令, 信令承载的方 式可以是 PDCCH信令, 也可以是 MAC层信令, 还可以是 RRC层信令, 或是其 他能够承载 MCCH修改通知信息的控制信令。
当 UE接收到 MCCH修改通知信息后, 在其后的 MCCH修改边界, 即在下 一个 MCCH修改边界去读取更新的 MCCH内容,包括 MBMS业务信息和无线资 源分配相关信息等信息, 从而可以根据修改后的 eMBMS业务信息和无线承载 相关信息接收 MBMS业务。
通常情况下, MCCH信息以 repetition period在同一个 MCCI- ί' 改周期内进 行周期地发送, 以相同的内容重复发送, 如在一个 512ms内发送 MCCH修改通 知 2次, 在后续 512ms内发送更新了的 MCCH修改通知 2次, 此种情况下, 也可 以认为, 在发送更新了的 MCCH修改通知信息的周期的开始时刻就是 MCCH 修改边界, 或者说, 当发送与之前内容不同的 MCCH修改通知信息的周期的 开始时刻就是 MCCH的修改边界。
上述流程中, 由于 RN不支持 MBMS传输, 按照现有协议, RN不能通过 子帧从 DeNB接收 MCCH修改通知信息发送到 UE, 因此, 本实施例中, DeNB可以将 MCCII修改通知信息承栽在下行控制信令中(可以是公共控制信 令或者专用控制信令)发送给 RN, RN也可将 MCCH修改通知信息承载于下行 控制信令(可以是公共控制信令或者专用控制信令)发送给 UE。
与实施例一同理, DeNB发送 MCCH修改通知发送配置信息的时间可以由 系统指定或规范规定,且应该保证 RN或 UE在相应的 MCCH修改边界之前能够 接收到 (考虑到适当的传输时延等因素), 因此, RN从 DeNB接收到相关信息 后发送给 UF,, 也就能够保证 UE在相应的 MCCH修改边界之前能够接收到。 基于相同的技术构思, 本发明实施例还提供了一种 RN设备。
如图 16所示, 该 RN设备可以包括: 第一接收模块 501、 第一发送模块 502, 其中:
第一接收模块 501 , 用于从基站接收 MCCH修改通知信息; 该模块可通过 接收基站发送的下行控制信令, 接收其中携带的 MCCH修改通知信息;
第一发送模块 502, 用于将第一接收模块 501接收到的 MCCH修改通知信 息发送给用户设备。 该模块可在所述 MCCH修改通知信息对应的修改边界之 前, 将从基站接收到的 MCCII修改通知信息发送给用户设备, 该模块可通过 下行控制信令发送所述 MCCH修改通知信息。
通过以上描述可以看出, 针对 RN不支持 MBMS传输的情况, 通过 RN在 MCCII修改边界之前获取 MCCH修改通知信息,并在 MCCH修改边界之前,通 过下行控制信令将其发送给 UE, 从而使 UE能够根据该 MCCH修改通知信息, 及时在下一个 MCCH修改边界去读取更新的 MCCII内容,包括 MBMS业务信息 和无线承栽相关信息。 可见, 根据以上描述, RN可以及时将与 MBMS传输相 关的 MCCII修改通知信息发送到 UE, 从而使得 及时去接收 MCCII的更新内 容, 从而保证 UK对 MBMS业务相关信息的接收。
实施例十二
本实施例所涉及的网络架构可如上述图 12所示, 包括主控基站(DeNB ) 和 RN,其中, RN不支持 MBMS传输。针对这种情况,本实施例中 RN可在 DcNB 发送 MCCH修通通知信息的时刻监听 DeNB发送的 MCCI I修改通知信息, 并将 检测到的 MCCH修改通知信息发送给 UE, 从而保证 IJE能够及时接收 MCCH修 改通知信息, 以便根据该修改通知信息、 在下一个 MCCH修改边界去读取更 新的 MCCH内容, 包括 MBMS业务信息和无线资源分配相关信息等信息, 以 便正确接收 MBMS业务。
如图 17所示, 本发明实施例的流程可以包括:
步骤 601、 RN从 DeNB接收 MCCH修改通知发送配置信息。 其中, MCCII 修改通知发送配置信息可承载于下行控制信令。
步骤 602、 RN在 DeNB发送 MCCH修改通知信息的时刻, 根据接收到的 MCCII修改通知发送配置信息, 在相应位置监听 DeNB发送的 MCCH修改通知 信息。可选的, RN在接收到 MCCH修改通知信息后,可向 DeNB返回确认信息。
步骤 603、 RN在监听到 MCCH修改通知信息后, 在下一个 MCCH修改边界 之前, 将在此之前从 DeNB接收到的 MCCH修改通知信息发送给 UE, 使 可 以不必在 DeNB规定的 MCCH修改通知信息发送时刻去接收该通知信息。
该步骤中, 若 MBMS业务信息和无线资源分配相关信息没有改变, 则 i)cNB有可能在规定的发送 MCCII修改通知信息时没有发送 MCCH修改通知 信息, 使 RN监听不到 MCCH修改通知信息, 则不会向 Uli发送。
该步骤中, RN可以将 MCCH修改通知信息承载于公共或者专用控制信令 发送给 UE。 该控制信令可以是 PDCCH信令, 也可以是 MAC层信令, 还可以 是 RRC层信令, 或是其他能够承载 MCCH修改通知信息的控制信令。
当 接收到 MCCH修改通知信息后, 在其后的 MCCI- 'l"改边界, 即在下 一个 MCCII修改边界去读取更新的 MCCH内容,包括 MBMS业务信息和无线资 源分配相关信息等信息, 从而可以根据修改后的 eMBMS业务信息和无线承载 相关信息接收 MBMS业务。
上述流程中, RN接收 改通知信息的时间可由系统指定, 或者由 规范规定, 较佳地, 该时间是 DeNB发送 MCCH修改通知信息的时间, 或者其 他系统指定发送时刻。 其中, DeNB发送 MCCH修改通知信息的时间应该在相 应的 MCCII修改边界之间。
上述流程中, RN可将 MCCH修改通知信息承载于公共或者专用控制信令 发送给 UE。
基于相同的技术构思, 本发明实施例还提供了一种 RN设备。
如图 18所示, 该 RN设备可以包括第一接收模块 701、 第一发送模块 702, 其中:
第一接收模块 701, 用于从基站接收 MCCH修改通知信息; 第一发送模块 702, 用于将第一接收模块 701接收到的 MCCII修改通知信 息发送给用户设备。 该模块可在所述 MCCH修改边界之前, 发送所述 MCCII 修改通知信息, 发送信息时可通过下行控制信令发送所述 MCCH修改通知信 息。
该设备还可包括第三接收模块 703, 用于从基站接收 MCCII修改通知发送 配置信息, 以使第一接收模块 701能够根据该配置信息在相应位置接收 MCCI I 修改通知信息。
通过以上描述可以看出, 针对 RN不支持 MBMS传输的情况, 通过 RN在 MCCII修改边界之前, 在 DeNB发送 MCCH修改通知信息时接收到的 MCCII修 改通知信息发送给 UE, 从而使 UE能够根据该 MCCH修改通知信息, 及时在下 一个 MCCII修改边界去读取更新的 MCCH内容,包括 MBMS业务信息和无线承 栽相关信息。可见, 居以上描述, RN可以及时将与 MBMS传输相关的 MCCII 修改通知信息发送到 UE, 从而使得 UE及时去接收 MCCH的更新内容, 从而保 证 IJK对 MBMS业务相关信息的接收。 , 实施例十三
本实施例中, RN可将从 DeNB接收到的 MCCII修改通知发送配置信息发送 给 IJ ,一方面,使 UE在没能接收到该 RN所在小区之外的小区所发送的 MCCII 修改通知发送配置信息的情况下, 能够根据该 RN所发送的 MCCH修改通知发 送配置信息去读取修改后的 MCCH内容, 包括 MBMS业务信息和无线资源分 配相关信息, 从而保证用户设备对 MBMS业务相关信息的接收。
如图 19所示, 本实施例的流程可以包括:
步骤 801、 RN接收 DeNB发送的 MCCH修改通知发送配置信息.
该步骤中, DeNB可将 MCCH修改通知发送配置信息承载在下行控制信令 中, RN可通过接收 DeNB发送的下行控制信令,接收其中携带的 MCCH修改通 知发送配置信息。
步骤 802、 RN将接收到的 MCCH修改通知发送配置信息发送给 UE。
该步骤中, RN可将 MCCH修改通知发送配置信息承载于下行控制信令发 送给 Ul<:。
上述流程中的下行控制信令可以是专用控制信令如, PDCCH信令, 或 MAC层信令, 或 RRC层信令; 还可以是公共控制信令。
基于与本实施例相同的技术构思, 本发明实施例还提供了一种中继节点 设备。
如图 20所述, 该中继节点设备可以包括: 接收模块 901、 发送模块 902, 其中:
接收模块 901, 用于接收基站发送的 MCCH修改通知发送配置信息; 该模 块可通过接收基站发送的下行控制, 接收其中携带的 MCCH修改通知发送配 置信息;
发送模块 902, 用于将接收模块 901接收到的 MCCH修改通知发送配置信 息发送给用户设备。 该模块可将所述 MCCH修改通知发送配置信息承载于下 行控制信令发送。
实施例十四
本发明还提出了另一种 RN不支持 MBMS业务传输的实施例 , 即基站传输 MCCII修改通知发送配置信息给 RN, 而不需要将其发送给 UE, 如图 21所示。 这样, RN不需要通过信令去通知 UE, 减少了 RN与 UE间接口 (Uu接口)的开 销。本实施例中, RN为了消除在传输 MBMS业务的 MBSFN子帧中可能引入的 (对正在接收 MBMS业务的 UE的)干扰, RN可以将对应的 MBSFN子帧 (即 所述 MCCII修改通知发送配置信息所指示的 MCCH修改通知信息的发送位置) 传输数据信息的 OFDM ( Orthogonal Frequency Division Multiplexing, 正交频 分复用)符号设置为静默(Mute ), 即不调度用户, 从而不传输任何用户的数 掂信息; 还可以选择发或者不发任何导频信息。 这样, 虽然 UE不知道这些子 帧是 MBSFN子帧,会将其当作常规单播子帧去接收业务,但是由于 RN采取了 上述处理操作, UE不会接收到自己的调度信息和用户数据, 所以可以在一定 程度上降低引入的干扰和对 UE的影响。
基于与上述流程相同的技术构思, 本发明实施例还提供了一种 RN设备, 包括: 第一接收模块, 还可进一步包括设置模块, 其中:
第一接收模块, 用于从基站接收 MCCH修改通知发送配置信息; 设置模块, 用于将与所述第一接收模块接收到的所述 MCCH修改通知发 送配置信息所指示的发送 MCCH修改通知信息所对应的单频网多播广播 MBS1''N子帧中传输数据的正交频分复用 OFDM符号设置为静默。
需要说明的是, 本发明上述各实施例中所述的下行控制信令可以是专用 控制信令, 也可以是公共控制信令。
还需要说明的是, 本发明上述各实施例中, 若 MBMS业务信息和无线资 源分配相关信息没有改变, 则 DeNB有可能在规定的发生 MCCH修改通知信息 时没有发送 MCCH修改通知信息, 使 RN监听不到 MCCH修改通知信息, 则不 会向 UE发送。
通过以上的实施方式的描述, 本领域的技术人员可以清楚地了解到本发 明可借助软件加必需的通用硬件平台的方式来实现, 当然也可以通过硬件, 但很多情况下前者是更佳的实施方式。 基于这样的理解, 本发明的技术方案 本盾上或者说对现有技术做出贡献的部分可以以软件产品的形式体现出来, 该计算机软件产品存储在一个存储介质中, 包括若干指令用以使得一台计算 机设备(可以是个人计算机, 服务器, 或者网络设备等)执行本发明各个实 施例所述的方法。
本领域技术人员可以理解附图只是一个优选实施例的示意图, 附图中的 模块或流程并不一定是实施本发明所必须的。
本领域技术人员可以理解实施例中的装置中的模块可以按照实施例描述 进行分布于实施例的装置中, 也可以进行相应变化位于不同于本实施例的一 个或多个装置中。 上述实施例的模块可以合并为一个模块, 也可以进一步拆 分成多个子模块。
上述本发明实施例序号仅仅为了描述, 不代表实施例的优劣。
以上公开的仅为本发明的几个具体实施例, 但是, 本发明并非局限于此, 任何本领域的技术人员能思之的变化都应落入本发明的保护范围。
