Description

多播广播业务的承载指示方法与装置 技术领域
本发明涉及多播广播业务( MBS, Multicast Broadcast Service ) 的承载 方式指示技术, 尤其涉及一种全球微波接入互操作性 (WiMAX, World Interoperability for Microwave Access ) 网络中多播广播业务区域 ( MBS Region ) 中 MBS承载的指示方法与装置。 背景技术
MBS是从一个数据源向多个目标传送数据的技术, MBS能提高网络资 源, 尤其是空中接口资源的利用率。 随着多媒体共享业务的应用与推广, 高效地进行多播广播业务传输, 对于下一代宽带移动通信系统变得尤为重 要。
基于 WiMAX的 MBS支持两种接入模式: 单基站接入和多基站接入。 在多基站接入模式下, 定义了 MBS域(MBS zone )的概念, 即一组基站的 集合, 每个 MBS zone对应一个 MBS zone标识(MBS zone ID )。 一个基站 可以同时属于多个 MBS zone。 属于同一个 MBS zone 的多个基站在发送 MBS时可以进行宏分集,即在同样的时频资源上发送相同内容的多播业务, 用户终端接收时可以获得宏分集增益。
为了满足下一代宽带移动通信系统中高性能和低延迟的业务应用, WiMAX空口演进标准 802.16m中的帧结构采用了超帧、帧和子帧的三层设 计方式。 图 1为 802.16m标准中规定的帧结构示意图, 如图 1所示。 每个 超帧由四个帧组成, 在第一帧之前还设置有帧头(图中斜线覆盖区域), 每 个帧由八个子帧组成, 每个子帧中包括六个符号。
在下一代 WiMAX技术中, 多播广播业务称为增强的多播广播业务 ( E-MBS , Enhanced-Multicast Broadcast Service ), 期望获得比 802.16 e的 MBS更好的性能, 而 802.16e的 MBS zone在下一代 WiMAX技术中称为 E-MBS zone。 另夕卜,在下一代 WiMAX技术中, 系统引入了多载波, E-MBS 业务的承载可以采用两种方式: 一种是专用载波方式, 即 E-MBS业务独占 某个载波上的所有时频资源; 另一种是共享载波方式, 即 E-MBS业务与单 播业务共享载波上的时频资源。
在下一代 WiMAX的技术方案中,资源分配指示分为两部分: E-MBS 区 域( E-MBS region, 也称为多播广播业务区域 )的指示和 E-MBS MAP的指 示。 其中 E-MBS 区域的指示是描述若干超帧上的 E-MBS子帧的分布, 这 些 MBS 子帧可以属于一个 E-MBS zone ,也可以属于多个 E-MBS zone; 而 E-MBS MAP是更进一步的 E-MBS 业务的资源分配,描述的是一个 E-MBS zone在一个调度间隔内的各个多播广播业务或者各个多播广播业务组分到 的具体资源。
业界现有方案中有超帧、 帧、 子帧三级指示的方法指示 E-MBS区域, 这种方式虽然有很强的灵活性, 但是开销也会随着灵活性的增强而剧烈增 大。 由于 E-MBS区域的指示信息是广播信息发送的, 因此, 完全由超帧、 帧和子帧三级描述没有任何分布规律的多播广播业务子帧是不现实的。
业界现有方案中还有分段指示的方法, 即用 1比特信息描述 N个连续 超帧内是否有多播广播业务子帧, 如果比特值表示含有多播广播业务子帧, 则对应的 N个超帧内都包括多播广播业务子帧, 并且这些超帧内的所有帧 都以相同的子帧分布图样包括多播广播业务子帧。 这种多播区域的指示方 式的有点是开销非常小, 但是存在着很严重的缺点: 灵活性很差; 资源分 配粒度太大, 粒度单位为 4χΝ个子帧; 当资源需求较小时, 一方面可能由 于粒度问题不能完成分配, 另一方面由于资源分配粒度过大而需要平均分 摊到很多帧上, 每帧的多播广播业务子帧数量比较少, 不利于终端省电。 发明内容
有鉴于此, 本发明的主要目的在于提供一种多播广播业务的承载指示 方法与装置, 能快捷地指示出承载 MBS的资源位置。
为达到上述目的, 本发明的技术方案是这样实现的:
一种多播广播业务的承载指示方法, 包括:
设置多播广播业务的子帧级及超帧级指示信息, 或子帧级及帧级指示 信息, 并通知用户终端。
优选地, 所述超帧级指示信息指示承载有多播广播业务的超帧中, 每 个帧均承载有多播广播业务, 且所述每个帧中承载多播广播业务的子帧图 样均相同。
优选地, 承载有多播广播业务的超帧中承载多播广播业务的子帧图样 为两种以上时, 为每种子帧图样的超帧分别设置子帧级及超帧级指示信息。
优选地, 所述超帧级指示信息通过与所指示超帧数目相等的比特位来 指示每个超帧中是否承载有多播广播业务。

本发明在没有增大多少开销的情况下, 增加了 MBS承载的灵活性, 使 承载 MBS的资源分配粒度更合理,使用户终端仅侦听自身感兴趣的时频资 源即可, 使用用户终端更省电。 本发明使子帧资源的承载更灵活, 通过指 示信息即可确定出承载 MBS的资源位置。 附图说明

本发明的基本思想是: 对于超帧指示域中的 MBS的承载位置, 设置承 载 MBS的超帧的指示信息以及子帧级的指示信息, 当 MBS的承载资源变 化时, 特别是子帧级的 MBS承载图样变化时, 将更改超帧指示域中的子帧 级的指示信息。也可以设置承载 MBS的帧的指示信息以及子帧级的指示信 息, 通过上述的指示信息确定出承载 MBS的资源位置, 当子帧级的 MBS 承载图样变化时, 更改超帧指示域中的子帧级的指示信息即可。 本发明在 没有增大多少开销的情况下, 增加了 MBS承载的灵活性, 使承载 MBS的 资源分配粒度更合理, 使用户终端仅侦听自身感兴趣的时频资源即可, 使 用用户终端更省电
为使本发明的目的、 技术方案和优点更加清楚明白, 以下举实施例并 参照附图, 对本发明进一步详细说明。
实施例一
系统中每 N个超帧指示一次, 该 N值可根据系统中的 MBS在子帧中 的承载方式而改变, 当系统中承载 MBS子帧图样固定时, N值为固定值, 承载 MBS子帧图样对应的指示信息也可以为固定值。 本发明中, 用 1比特 表示这 N个超帧是否承载有多播广播业务子帧, 1表示有, 0表示该 N个 超帧中未承载任何的 MBS。 当 N个超帧中承载有 MBS时, 则用 N比特图 样描述哪些超帧有 MBS。对应比特位为 1的超帧内每个帧上都有多播业务, 并且各帧上承载 MBS子帧配置完全相同。
承载 MBS的指示信息如表 1所示:
Figure imgf000008_0001

当超帧级指示信息中指示上述 8个超帧不包括多播广播业务子帧时, 子帧级指示信息(000 ) 不存在。
上述多播广播业务区域指示信息在超帧的超帧头中发送, 其发送间隔 可以为上述的 8个超帧, 也可以在 8个超帧内重复发送多次。
子帧级指示信息可以是几种已定义的子帧图样的编号。 如表 2及表 3 所示: 子帧图

子帧级指示信息还可以是子帧个数信息, 指示从默认的位置开始的向 前或向后连续的下行子帧中均承载有 MBS。 当然, 子帧级指示信息还可以 是子帧起始位置信息及子帧个数信息, 从指示的子帧起, 向前或向后连续 的下行子帧中均承载有 MBS。
本示例中的子帧级指示信息也同样适用于以下各示例中的子帧级指示 信息。
