- LTE Long Term Evolution
- uplink and downlink subframe ratios may be applied to the TDD MBMS dedicated carrier system.
- LTE MBMS defines single cell transmission mode (Single Cell transmission)
- SFN mode multiple base stations in the same SFA (single-frequency network area) use the same modulation and coding technology and transmit the same data at the same frequency to improve the reception efficiency of the cell edge users.
- MCE Multi-cell/multicast Coordination
- MBSFN Multimedia Broadcast Multicast Service Signal Frequency Network
- Entity multi-cell/multicast coordination entity, responsible for allocating and managing radio broadcast resources of all base stations in the SFA.
- each MBMS service area (MBMS service)
- MBSFN area consists of multiple adjacent single cells that provide the same MBMS service. All cells in each MBSFN area use the same uplink and downlink subframe ratio.
- the MBSFN area can use different uplink and downlink subframe ratios according to the service type requirements. For example, MBSFN area 1 uses 0: 10 ratio; adjacent MBSFN area 2 uses 1 : 8 ratio. Since the MBSFN edge has a reserved cell (Reserve).

TDD单播与混合载波***中, 共有 8种可以使用的上下行子帧配比。
[6] LTE MBMS (Multimedia Broadcast multicast
Service, 多媒体多播广播服务) 专用载波***中, 全部吋频资源均用于下行资 源传输。 在 TDD
MBMS专用载波***中, 只釆用上下行子帧配比 0: 10的子帧配比。 在带上行反 馈 LTE
MBMS专用载波***中, 由于会有上行子帧出现, 可能会有其他上下行子帧配 比 (例如: 2:7, 1:8等) 应用在 TDD MBMS专用载波***中。
[7] LTE MBMS定义了单小区传输模式 (Single Cell transmission
mode) 与单步 网模式 (Single Frequency Network transmission
mode) 。 在 SFN模式下, 相同 SFA (单频网区域) 下的多个基站在相同吋间与相 同频率釆用相同调制编码技术, 发送相同数据, 以提高小区边缘用户的接收效
果。 为实现 MBSFN (Multimedia Broadcast multicast service Signal Frequency Network, 多媒体广播多播服务单频网) 传输方式, 在接入网中引入 MCE (Multi -cell/multicast Coordination
Entity, 多小区 /多播协调实体) , 负责对 SFA内所有基站的无线广播资源进行分 配和管理。
[8] 在 TDD MBMS***中, 每一个 MBMS服务区域 (MBMS service
area) 下可以包括多组提供不同 MBMS业务的 MBSFN区域。 每一个 MBSFN区域 由多个提供相同 MBMS业务的相邻单小区组成。 每一个 MBSFN区域内的所有小 区使用相同的上下行子帧配比。 MBSFN区域间可以根据业务种类需求釆用不同 的上下行子帧配比, 例如 MBSFN区域 1釆用 0: 10配比; 相邻 MBSFN区域 2釆用 1 : 8配比。 由于 MBSFN边缘有保留小区 (Reserve
cell) 和仅传输小区 (Transmission only
Cell) 存在, 其作用在于保障 MBSFN区域不受到外部的频率干扰, 并且可以克 服由于相邻 MBSFN区域釆用不同上下行配比而产生的干扰。 MBSFN区域间上下 行子帧配比的应用和保留小区与仅传输小区的配置通过 MCE进行控制。
[9] 现有 LTE
TDD单播与 MBMS混合载波***中, 由于存在着 8种不同的上下行子帧配比方式 。 ***根据业务需求通过基站在不同上下行子帧配比间进行半静态切换。 基站 可以通过"冷启动"或其他方式重新设置本小区的子帧配比。 子帧配比确定后, 一 段吋间内, 只使用一种上下行子帧配比。
[10] 然而, 本发明的发明人通过深入分析发现: 由于在一段吋间内只能使用一种上 下行子帧配比, 若***的需求为在 20ms内只需要一个上行子帧, 则根据现有子 帧的配比不能满足此种需求, 例如, 若在 20ms内使用 1 : 8+1: 8配比, 则会在 20 ms内使用两个上行子帧, 从而造成上行传输资源的浪费。 另外, 在一段吋间内 基站按照 0:10的配比进行资源分配、 传输数据, 在一段吋间后当基站根据需求重 新设置上下行子帧配比为 1:8后, 基站即按照 1:8的上下行资源配置分配, 传输数 据, 由于在一段吋间内只使用 0:10的上下行子帧配比, 会造成只发生下行数据传 输, 而没有上行数据传输, 而在下一个吋间段只使用 1:8上下行子帧配比, 会造
成在这段吋间只使用一个上行数据传输, 因此每个吋间段内使用单一的上下行 子帧配比不但会使上下行数据传输不均匀, 而且不能满足***的需求。 还有, 现有的上下行子帧配比都只支持 10ms的发生周期的上下行传输, 不能支持 10ms 以上的发生周期上下行传输。
[11] 发明内容
[12] 本发明实施例的目的是提供一种配置上行子帧与下行子帧配比的方法与装置, 用以合理分配上下行资源, 避免资源浪费。
[13] 本发明实施例的目的是提供一种数据传输的方法, 用以合理分配上下行资源, 避免资源浪费。

[37] 实施本发明的方式
[38] 下面将结合附图对本发明的实施方式详细描述。
[39] 本发明第一实施例提供一种配置上行子帧与下行子帧配比的方法, 包括:
[40] ***根据需求配置上行子帧与下行子帧的配比;
[41] 所述配置是将至少两种上行子帧与下行子帧的第一配比混合配置。
[42] 其中, 所述***根据需求具体为: ***根据小区内的用户数、 或不同业务类型 或运营商自身业务需求。
[43] 其中, 所述***根据需求配置上行子帧与下行子帧的配比具体为:
[44] ***根据需要确定上行子帧与下行子帧的发生周期; 根据所述发生周期配置上 行子帧与下行子帧第一配比的数量。 由于所述第一配比可以为下表 1中的具体 8 种配比中任何一种, 因此所述***根据需求配置上行子帧与下行子帧的配比也 可以具体为: 根据所述配比选择所述第一配比的序号和数量。
[45] 所述的发生周期根据混合配制中参与的上行子帧与下行子帧第一配比的数量确 定。 其中所述上行子帧与下行子帧第一配比的数量是***根据小区内的用户数 、 或不同业务类型或运营商自身业务需求来确定, 其中不同的业务类型可以为
互动, 或点播等业务, 针对这部分业务, 用户需要在发生周期 50ms发一次上行 数据, 因此需要釆用 5种配比的混合配置来达到***的需求。 其中根据运营商自 身的业务需求, 例如运营商需要小区内全部用户都反馈广播质量, 可能就要用 1 : 8才能承载所有反馈信息; 若只有少部分用户反馈的话, 就需要 1 : 8 + 0: 10 配比混合配置的方式来实现。
[46] 其中, 所述将至少两种上行子帧与下行子帧第一配比混合配置具体为: 一定的 周期内将至少两种上行子帧与下行子帧的第一配比混合后重复配置; 或一定的 周期内将第一至少两种上行子帧与下行子帧的第一配比混合重复配置, 在一定 周期后切换为第二至少两种上行子帧与下行子帧的第一配比混合重复配置; 或 一定的周期将至少两种上行子帧与下行子帧的第一配比混合重复配置, 在一定 周期后切换为一种上行子帧与下行子帧的第一配比配置。
[47] 所述的发生周期大于 10ms。
[48] LTE
TDD***中 10ms帧中带有上行子帧的配比共有 8种, 如表 1所示, 其中 D代表下行 子帧, U代表上行子帧, S代表特殊子帧。
[49] 表 1 TDD***上下行子帧配比
[51] 其中混合配置不同上下行配比的子帧可以是表 1中任何两种或两种以上的混合 , 其中配比序号 0, 1, 2, 6的上下行子帧配比周期为 5ms, 在本表中统一为以 10 ms周期内两次重复相同配比, 其余上下行子帧配比序号周期为 10ms。 根据*** 的需求, 若需得到发生周期 20ms的一个上行子帧的数据传输, 可釆用上下行子
帧配比为 1 : 8子帧配比和 0: 10子帧配比的混合配置, 若需得到发生周期 30ms的 一个上行子帧的数据传输, 可釆用上下行子帧配比为 0: 10, 0: 10和 1 : 8子帧 配比的混合配置, 若需得到发生周期 30ms的二个上行子帧的数据传输, 可釆用 上下行子帧配比为 0: 10, 0: 10和 2: 7子帧配比的混合配置、 或 0: 10, 1: 8和 1: 8子帧配比的混合配置。 因此具体发生的混合配置的配比是根据对上行或下 行子帧的需求量确定混合配置的子帧的比例。
[52] 一段吋间内***根据需求将至少两种上行子帧与下行子帧第一配比混合配置, 即在一个发生周期内至少存在两种上行子帧与下行子帧第一配比, 从而在一个 发生周期内可灵活配置上行子帧与下行子帧配比, 以满足***对于上行或下行 子帧的需求, 而且在一段吋间内, 使用至少两种上行子帧与下行子帧第一配比 , 不但可以合理配置上行或下行子帧的数据传输, 而且避免单一配比造成的上 行或下行资源的浪费。 另外, 因为釆用混合配比, 因此不会造成在一段吋间内 只发生下行数据传输, 而没有上行数据传输, 使一段吋间内上下行数据传输更 加均匀。 由于发生周期包括至少两个上行子帧与下行子帧第一配比的个数, 因 此可以支持 10ms以上的发生周期上下行传输。
[53] 本发明第二实施例提供一种配置上行子帧与下行子帧配比的方法, 如图 1所示 , 为在一定的周期内将上下行子帧配比为 1 : 8子帧配比和 0: 10子帧配比在 20ms 的发生周期内混合后重复配置, 从而在发生周期 20ms内发生一次上行子帧传输 , 具体包括:
[54] ***根据需求配置上行子帧与下行子帧的配比;
[55] 所述配置是将上行子帧与下行子帧第一配比分别为 1 : 8子帧配比和 0: 10子帧 配比按照发生周期 20ms混合重复配置。
[56] 其中, 1 : 8子帧配比和 0: 10子帧配比的混合配比是***要求在发生周期 20ms 内发生一次上行子帧传输来确定的, 即在发生周期 20ms内釆用 2个上行子帧与下 行子帧配比, 其中 1个上行子帧与下行子帧配比必需支持一次上行子帧传输。 其 中***的具体需求是***根据小区内的用户数、 或不同业务类型或运营商自身 业务需求来确定。
[57] 上述的重复配置是在一定的周期内使用 1 : 8子帧配比和 0: 10子帧配比按照发
生周期 20ms连续配置。
[58] 由此可见, 在一定的周期内***根据需求使用 1 : 8子帧配比和 0: 10子帧配比 按照发生周期 20ms连续配置, 不但可以满足***在发生周期 20ms发生一次上行 传输的要求, 而且***根据需求能够合理的分配上行与下行的传输, 避免了一 段吋间内只釆用一种子帧配比造成的上行或下行子帧分配不均匀现象, 从而避 免了资源浪费。 另外, 还可以支持 20ms以上的发生周期上下行传输, 进而能够 提供更长周期的一次上下行传输。
[59] 本发明第三实施例提供一种配置上行子帧与下行子帧配比的方法, 如图 2所示 , 为在一定的周期内将上下行子帧的配比为 1 : 8子帧配比和 0: 10子帧配比在 20 ms的发生周期内混合后重复配置, 然后再切换为 1 : 8子帧配比、 0: 10子帧配比 和 0: 10子帧配比在 30ms的发生周期内混合重复配置, 在一段吋间的不同发生周 期内均发生一次上行子帧传输, 具体包括:
[60] ***根据需求配置上行子帧与下行子帧的配比;
[61] 所述配置是在一段吋间内将上行子帧与下行子帧配比分别为 1 : 8子帧配比和 0 : 10子帧配比按照发生周期 20ms混合重复配置, 在下一段吋间内切换为上行子 帧与下行子帧配比分别为 1 : 8子帧配比、 0: 10子帧配比和 0: 10子帧配比按照 发生周期 30ms混合重复配置。
[62] 其中, ***根据小区内的用户数、 或不同业务类型或运营商自身业务需求来确 定在一定的吋间内釆用 1 : 8子帧配比和 0: 10子帧配比按照发生周期 20ms混合重 复配置, 若***确定该混合配置不能满足***的实际要求, 则切换为 1 : 8子帧 配比、 0: 10子帧配比和 0: 10子帧配比按照发生周期 30ms混合重复配置, 即系 统根据是在发生周期 20ms内发生一次上行子帧传输, 还是发生周期 30ms内发生 一次上行子帧传输, 来确定混合配制是釆用 1 : 8子帧配比和 0: 10子帧配比, 还 是釆用 1 : 8子帧配比、 0: 10子帧配比和 0: 10子帧配比。
[63] 另外, 本实施例只给出发生周期 20ms发生一次上行子帧传输切换为发生周期 30 ms发生一次上行子帧传输的例子, 对于发生周期大于 10ms发生不同次数的上行 子帧传输或下行子帧传输的例子, 可根据上述表 1中的配比进行灵活的混合。
[64] 由此可见, 在一定的周期内***根据需求使用 1 : 8子帧配比和 0: 10子帧配比
按照发生周期 20ms连续配置, 当***需求变化后, 可釆用 1 : 8子帧配比、 0: 10 子帧配比和 0: 10子帧配比按照发生周期 30ms连续配置, 不但可以满足***在发 生周期 20ms发生一次上行传输的要求, 而且***需求变化吋通过切换混合配比 以满足发生周期 30ms发生一次上行传输的要求, ***根据需求灵活的对混合配 比进行切换, 不但能更合理的分配上行与下行的传输, 而且能够避免一段吋间 内只釆用单一混合配比引起的上行或下行子帧分配不均匀的现象, 从而避免了 资源浪费。 另外, 还可以支持 20ms或 30ms发生周期上下行传输, 进而能够提供 更长周期的一次上下行传输。
[65] 本发明第四实施例提供一种配置上行子帧与下行子帧配比的方法, 如图 3所示 , 为在一定的周期内将上下行子帧的配比为 1 : 8子帧配比和 0: 10子帧配比在 20 ms的发生周期内混合后重复配置, 然后再切换为 0: 10子帧配比的配置, 即在一 段吋间内, 20ms发生一次上行子帧传输切换为 10ms无上行子帧传输, 具体包括
[66] ***根据需求配置上行子帧与下行子帧的配比;
[67] 所述配置是在一段吋间内将上行子帧与下行子帧配比分别为 1 : 8子帧配比和 0 : 10子帧配比按照发生周期 20ms混合后重复配置, 在下一段吋间内切换为 0: 10 子帧配比的配置。
[68] 其中, ***根据小区内的用户数、 或不同业务类型或运营商自身业务需求来确 定在一定的吋间内釆用 1 : 8子帧配比和 0: 10子帧配比按照发生周期 20ms混合重 复配置, 若***确定不需要上行子帧的传输, 则切换为 0: 10子帧配比, 即*** 根据是在发生周期 20ms内发生一次上行子帧传输, 还是发生周期 10ms内无上行 子帧传输, 来确定混合配制是釆用 1 : 8子帧配比和 0: 10子帧配比, 还是釆用 0 : 10子帧配比。
[69] 另外, 本实施例只给出发生周期 20ms发生一次上行子帧传输切换为 10ms无上 行子帧传输的例子, 对于发生周期大于 10ms发生不同次数的上行子帧传输或下 行子帧传输切换为现有单一子帧配比的例子, 可根据上述表 1中的配比进行灵活 的混合。
[70] 由此可见, 在一定的周期内***根据需求使用 1 : 8子帧配比和 0: 10子帧配比
按照发生周期 20ms连续配置, 当***需求变化后, 可釆用 0: 10子帧配比, 如此 不但可以满足***在发生周期 20ms发生一次上行传输的要求, 而且***需求变 化吋还可切换现有子帧配比的传输需求, ***根据需求灵活的对混合配比进行 切换, 不但能更合理的分配上行与下行的传输, 而且能够避免一段吋间内只釆 用单一混合配比引起的上行或下行子帧分配不均匀的现象, 从而避免了资源浪 费。
[71] 本发明第五实施例提供一种数据传输的方法, 如图 4所示, 具体包括如下步骤
[72] 401: 接收***发送的根据需求配置上行子帧与下行子帧的配比;
[73] 402: 根据所述的配比在对应的上行或下行子帧上传输数据;
[74] 所述接收***发送的根据需求配置上行子帧与下行子帧的配比具体为:
[75] 基站接收 MCE配置的上行子帧与下行子帧的配比; 或终端接收基站转发的上行 子帧与下行子帧的配比。
[76] 其中, 接收***发送的根据需求配置上行子帧与下行子帧的配比具体包括: 接 收***根据所发送业务的资源需求配置上行子帧与下行子帧的配比。 另外, MC E可以通过使用子帧配比混合来对无线资源进行控制,
MCE通过 M2接口将子帧配比的配置信息通知基站, 基站通过承载在 SFN方式广 播信道, 或单播方式广播信道 PBCH (Physical Broadcast
物理多播信道) 、 或其他公共信道的信令通知 MBSFN区域内的所有终端。 相应 的保留小区 (Reserve cell) 与仅传输小区 (Transmission only
cell) 的配置更改也由 MCE控制, 通过对这些小区的子帧配置, 可以将在相邻 M
BSFN区域与本 MBSFN区域可能存在干扰的子帧设置为哑子帧, 在此子帧内不进 行数据传输, 以消除由 TDD***所造成的上下行干扰。
[77] 所述配置是将至少两种上行子帧与下行子帧的第一配比混合配置。
[78] ***根据需要确定上行子帧与下行子帧的发生周期; 根据所述发生周期配置上 行子帧与下行子帧的第一配比的数量。 其中, 所述第一配比可以为表 1中的具体
8种配比中任何一种。 所述的发生周期根据混合配制中的上行子帧与下行子帧的 第一配比的数量确定。 其中所述上行子帧与下行子帧第一配比的数量是***根 据小区内的用户数、 或不同业务类型或运营商自身业务需求来确定, 其中不同 的业务类型可以为互动, 或点播等业务, 因这部分业务用户需要在发生周期 50m s发一次上行数据, 因此需要釆用 5种配比的混合配置来达到***的需求。 根据运 营商自身的业务需求, 例如运营商需要小区内全部用户都反馈广播质量, 可能 就要用 1 : 8才能承载所有反馈信息; 若只用少部分用户反馈的话, 就需要 1 : 8
+ 0: 10配比混合配置的方式来实现。
[79] 所述将至少两种上行子帧与下行子帧的第一配比混合配置具体为: 一定的周期 内将至少两种上行子帧与下行子帧的第一配比混合后重复配置; 或一定的周期 内将第一至少两种上行子帧与下行子帧的第一配比混合重复配置, 在一定周期 后切换为第二至少两种上行子帧与下行子帧的第一配比混合重复配置; 或一定 的周期将至少两种上行子帧与下行子帧的第一配比混合重复配置, 在一定周期 后切换为一种上行子帧与下行子帧的第一配比配置。 具体如第二、 第三、 第四 实施例所述。
[80] 所述的发生周期大于 10ms。
[81] 其中混合配置不同上下行配比的子帧可以是表 1中任何两种或两种以上子帧配 比的混合, 其中配比序号 0, 1, 2, 6的配比周期为 5ms, 在 10ms内两次重复相同 配比, 其余配比序号的配比周期为 10ms。 根据***需求, 若需得到发生周期 20m s的一个上行子帧的数据传输, 可釆用上下行子帧得配比为 1 : 8子帧配比和 0: 10 子帧配比的混合配置, 若需得到发生周期 30ms的一个上行子帧的数据传输, 可 釆用上下行子帧的配比为 0: 10, 0: 10和 1 : 8子帧配比的混合配置, 若需得到 发生周期 30ms的二个上行子帧的数据传输, 可釆用上下行子帧的配比为 0: 10, 0: 10和 2: 7子帧配比的混合配置、 或 0: 10, 1: 8和 1 : 8子帧配比的混合配置 。 具体发生的混合配置的子帧配比的比例是根据对上行或下行子帧的需求量确 定的。
[82] 一段吋间内***根据需求将至少两种上行子帧与下行子帧的第一配比混合配置 , 即在一个发生周期内至少存在两种上行子帧与下行子帧的第一配比, 如此在
一个发生周期内通过灵活配置上行子帧与下行子帧配比, 能够满足***对于上 行或下行子帧的需求, 而且在一段吋间内, 使用至少两种上行子帧与下行子帧 第一配比, 不但可以合理配置上行或下行子帧的数据传输, 避免单一配比造成 的上行或下行资源浪费。 另外, 因为釆用混合配比, 不会造成在一段吋间内只 发生下行数据传输, 而没有上行数据传输的现象, 使一段吋间内上下行数据传 输更加均匀。 另外, 由于发生周期包括至少两个上行子帧与下行子帧的第一配 比, 因此可以支持 10ms以上的发生周期上下行传输。
[83] 本发明第六实施例提供一种配置上行子帧与下行子帧配比的装置, 该装置包括
[84] 配置单元, 用于根据***需求配置上行子帧与下行子帧的配比;
[85] 其中, 所述配置是将至少两种上行子帧与下行子帧的第一配比混合配置。
[86] 所述将至少两种上行子帧与下行子帧的第一配比混合配置具体为: 一定的周期 内将至少两种上行子帧与下行子帧的第一配比混合后重复配置; 或一定的周期 内将第一至少两种上行子帧与下行子帧的第一配比混合重复配置, 在一定周期 后切换为第二至少两种上行子帧与下行子帧的第一配比混合重复配置; 或一定 的周期将至少两种上行子帧与下行子帧的第一配比混合重复配置, 在一定周期 后切换为一种上行子帧与下行子帧的第一配比配置。 具体如第二、 第三、 第四 实施例所述。
[87] 配置单元可通过下面至少一种方式来判断***中所使用的子帧配比是否需要切 换: 小区内用户数、 不同业务类型, 和运营商所需要的业务反馈周期。
[88] 本发明第七实施例提供一种数据的传输的装置, 如图 5所示, 该装置 50包括: [89] 接收单元 51, 用于接收***发送的根据需求配置上行子帧与下行子帧的配比; [90] 传输单元 52, 用于根据所述的配比在对应的上行或下行子帧上传输数据; [91] 其中, 所述配置是将至少两种上行子帧与下行子帧的第一配比混合配置。
[92] 接收***发送的根据需求配置上行子帧与下行子帧的配比具体包括: 接收*** 通过承载发送的根据需求配置上行子帧与下行子帧的配比。 另外, MCE通过使 用子帧配比混合来对无线资源进行控制, MCE通过 M2接口将子帧配比的配置信 息通知基站, 基站通过承载在 SFN方式广播信道, 或单播方式广播信道 PBCH (
Physical Broadcast Channel) , 或单播方式动态广播信道
DBCH (Dynamic— Broadcast Channel ) 或 PMCH (Physical Multicast CHannel 物理多播信道) 、 或其他公共信道的信令通知 MBSFN区域内的所有终端。 相应 的 MBSFN区域所属的保留小区 (Reserve cell) 与只传输小区 (Transmission only cell) 的配置更改也由 MCE进行控制,
通过对这些小区的子帧配置, 可以将在相邻 MBSFN区域与本 MBSFN区域可能存 在干扰的子帧设置为哑子帧, 在此子帧内不进行数据传输, 以消除由 TDD*** 所造成的上下行干扰。
[93] 所述将至少两种上行子帧与下行子帧的第一配比混合配置具体为: 一定的周期 内将至少两种上行子帧与下行子帧的第一配比混合后重复配置; 或一定的周期 内将第一至少两种上行子帧与下行子帧的第一配比混合重复配置, 在一定周期 后切换为第二至少两种上行子帧与下行子帧的第一配比混合重复配置; 或一定 的周期将至少两种上行子帧与下行子帧的第一配比混合重复配置, 在一定周期 后切换为一种上行子帧与下行子帧的第一配比配置。 具体如第二、 第三、 第四 实施例所述。
[94] 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以 通过硬件实现, 也可以可借助软件加必要的通用硬件平台的方式来实现基于这 样的理解, 本发明的技术方案可以以软件产品的形式体现出来, 该软件产品可 以存储在一个非易失性存储介质 (可以是 CD-ROM, U盘, 移动硬盘等) 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。 总之, 以上所述仅为本发明的较 佳实施例。
[95] 虽然通过参照本发明的某些优选实施方式, 已经对本发明进行了图示和描述, 但本领域的普通技术人员应该明白, 可以在形式上和细节上对其作各种改变, 而不偏离本发明的精神和范围。
