图 2 示出了根据本发明的一个具体实施方式的一个网络拓朴结构 图， 图 2中包括移动站， 主中继站辅助中继站以及基站。 这里需要说明 的是， 本发明中的主中继站或辅助中继站的概念只是为了从功能上进行 区别， 在现有技术中的中继站的基 上增加本发明的主中继站的功能即 可构成本发明的主中继站， 本发明中的辅助中继站的功能可由现有技术 中的中继站来实现， 即本发明中的辅助中继站与现有技术的中继站没有 区别。
本发明的技术方案既适用于数据包的单次传输， 也适用于数据包的 混合自动重传。在本发明的解决方案中，考虑到中继站的简单性和成本， 所有的数据传输的无线传输资源的分配都是由基站来执行的。 附图中所 示的 UL/DL MAP是指上行链路 /下行链路控制映射信息， 即基站分配的 传输资源信息。 移动站、 主中继站以及辅助中继站根据上 /下行映射信 息的规定的传输资源信息接收和发送数据 /管理信令，传输资源信息包 括时频资源信息以及调制格式编解码格式等相关信息。
下面根据图 3和图 4并结合图 2对数据包的上下行单次传输进行说 明。
数据包的上行单次传输
首先， 在步骤 Al l中，移动站在基站分配的传输资源上发送数据包 给主中继站与辅助中继站，辅助中继站在接收到该数据包后，在步骤 A 12 主中继站在先后接收到所述数据包的来自移动站以及辅助中继站 的两个副本之后， 在步骤 A13中将这两个副本进行合并处理， 获得该数 据包一个合并处理后的副本。 然后， 在步骤 A14中， 主中继站在基站分 配的传输资源上将合并处理后的副本发送给基站。 这样便完成了数据包 的一次上行传输过程。
优选地， 辅助中继站在步骤 A12中可同时将数据包发送给基站， 如 图 3中的虚箭头所示。 基站接收到来自主中继站的合并处理后的副本之 后， 将该数据包来自辅助中继站的副本与来自主中继站合并处理后的副 本再进行合并处理。 这样在该数据包的一次传输过程中， 两次利用了空 间分集， 大大提高了数据包传输的正确率。
数据包的下行单次传输
首先， 基站在步骤 A21中发送数据包给主中继站与辅助中继站。 辅 助中继站在接收到该数据包后， 在步骤 A22中， 在基站分配的传输资源 上将该数据包发送给主中继站。
主中继站在先后接收到所述数据包的来自移动站以及辅助中继站 的两个副本之后， 在步骤 A23中将这两个副本进行合并处理， 获得该数 据包一个合并处理后的副本。 然后， 在步骤 A24中， 在基站分配的传输 资源上将合并处理后的副本发送给移动站。 这样便完成了数据包的一次 上行传输过程。
优选地， 辅助中继站在步骤 A22中可同时将数据包发送给移动站， 如图 4中所示的虚箭头所示。 移动站接收到来自主中继站的合并处理后 的副本之后， 将该数据包来自辅助中继站的副本与来自主中继站合并处 理后的副本再进行合并处理。 这样在该数据包的一次传输过程中， 两次 利用了空间分集， 大大提高了数据包传输的正确率。 当然这样可能对移 动站的处理能力要求比较高， 现有技术中， 可能有些移动站还不能支持 合并功能。
虽然图 2中仅示出了两跳中继网络以及一个辅助中继站的拓朴结构 示意图， 本领域的技术人员应该理解本发明不限于图 2所示的网络拓朴 结构， 本发明的方法也可以应用至例如图 5所示的包括多个辅助中继站 的情形， 并且数据传输的源网络设备和目标网络设备也不限于基站或移 动站， 还可包括中继站， 如图 6所示， 并且在图 6所示的移动站与中继 站之间以及中继站与基站之间还可包括多个中继站。 图 2中所示的数据 传输的网络拓朴结构还可以级联， 例如图 7所示。 当然本发明的应用范 围不限于图 2以及图 5至图 Ί中所示的网络拓朴结构， 本领域的技术人 员可在图 2以及图 5至图 7中所示的网络拓朴结构上进行各种变形或者 组合。
这里需要说明的是， 上述数据包的多个副本的调制方式可以是不 同。 例如， 源网络设备发送数据包给主中继站与辅助中继站时， 采取的
16QAM调制方式， 在辅助中继站将该数据包的副本发送给主中继站时， 可采取 64QAM调制方式， 主中继站对接收到的该数据包的两个副本进 行对数似然比解调后， 进行合并， 然后再进行解码以及校验处理。 本发 明对具体采取的合并方式也不限， 例如， 追赶合并 （ CC， Chase
Combining) 以及递增冗余（ IR， Incremental. Redundancy)合并等皆适 用。
以上对本发明的方案应用于数据包的单次传输的情形进行了描述， 下面结合图 8至图 11以及图 2对本发明在自动混合重传中的应用进行描 述。
根据主中继站在对数据包的多个副本进行合并之后是否进行验证 以及根据验证结果发送指示数据包接收正确与否的接收指示消息将混 合自动重传分为主动混合自动重传和被动混合自动重传。
1. 主动混合自动重传
根据本发明的具体实施例 , 主动混合自动重传的特征在于主中继站 在接收到来自源网络设备的数据包经由多个不同传输路径的多个副本 后， 对多个副本进行合并处理之后得到一个合并后的副本， 对该合并后 的副本进行校验， 以判断是否正确接收到该数据包， 并将校验结果发送 给源网络设备以及基站。这里源网络设备包括移动站或中继站或基站。
1.1 数据包的上行传输
下面以图 2所示的网络拓朴结构为例， 根据附图 8对主动混合自动 重传中数据包的上行传输过程进行详细描述。
首先， 在步骤 B11中， 移动站在基站分配的传输资源上发送数据包 给主中继站与辅助中继站，辅助中继站在接收到该数据包后，在步骤 B 12 中在基站分配的传输资源上将该数据包发送给主中继站。
主中继站在先后接收到所述数据包的来自移动站以及辅助中继站 的两个副本之后， 在步骤 B13中将这两个副本进行合并处理， 获得该数 据包一个合并后的副本， 并对该合并后的副本进行校验， 以判断是否正 确接收该数据包。 具体的校验方式不限， 根据发送端采用的校验方式而 定， 目前常用的是循环冗余码校验。 进行校验处理之后， 主中继站在步 骤 B14中将校验结果发送给基站以及移动站。对于主中继站中数据包的 发送， 有两种处理方式： 一种是根据校验结果决定是否将该数据包合并 后的副本发送给基站， 即校验结果正确， 则在步骤 B15中将该数据包合 并后的副本发送给基站，如果不正确，则不发送该数据包合并后的副本； 另一种处理方式是不论校验结果对错， 在步骤 B15中将数据包合并后的 副本发送给基站。 这里需要说明的是， 步骤 B14与步骤 B15的执行不分 先后。
若主中继站数据包校验结果错误， 而不发送数据包合并后的副本给 基站， 则在步骤 B18中， 主中继站发送一个指示本中继站数据包校验结 果错误接收指示消息发送给移动站。 然后基站为该数据包分配资源进行 重传， 资源分配同数据包的第一次传输。
若主中继站将该数据包合并后的副本发送给基站 , 则基站在接收到 该副本后， 在步骤 B16中对该副本进行校验。 优选地， 基站还可以接收 辅助中继站在步骤 B12中发送的数据包的副本， 并将该数据包来自主中 继站的合并后的副本与来自辅助中继站的副本进行合并处理， 以获得合 并后的数据包， 并对该合并后的数据包进行校验处理。 在步骤 B17中， 基站发送指示基站数据包的校验结果的接收指示消息给主中继站。 优选 地， 基站还可以将指示数据包的校验结果的接收指示消息发送给辅助中 继站。
主中继站在接收到来自基站的指示数据包校验结果的接收指示消 息时， 如果基站的数据包校验结果正确或者主中继站的数据包校验结果 正确， 则在步骤 B18中， 主中继站发送一个指示本中继站数据包校验结 果正确的接收指示消息给移动站。 如果基站和主中继站的数据包校验结 果皆错误， 则在步骤 B18中， 主中继站发送一个本中继站指示数据包校 验结果错误的接收指示消息给移动站。
上述过程完成了数据包的第一次传输以及数据包接收正确与否的 通知过程。
如果基站中数据包的校验结果正确， 即基站正确接收该数据包， 则 该数据包的传输就完成了。
如果基站没有正确接收该数据包， 并且主中继站也没有正确接收该 数据包， 则基站为该数据包分配资源给移动站、 辅助中继站和主中继站 进行重传（为简明起见， 图 8 中未示出移动站重传的步骤）， 其重传过 程可以与图 8中所示的步骤相同， 也可以稍有不同。 在第二次传输过程 中， 主中继站接收到数据包来自移动站和在辅助中继站的两个副本之 后， 可以仅对这两个副本进^"合并处理后进行校^ r处理， 也可以对这两 个副本进行合并处理之后再与第一次传输过程中合并后的副本再进行 合并处理， 然后再进行校验处理。 同样， 在第二次传输过程中， 基站在 接收到来自主中继站的数据包的一个合并后的副本后， 可以与第一次数 据传输过程中的所接收的合并后的副本合并之后再进行校验； 或者基站 在接收到来自主中继站的数据包的一个合并后的副本以及来自辅助中 继站的副本之后， 可以仅对这两个副本进行合并处理后进行校验处理， 也可以对这两个副本进行合并处理之后再与第一次传输过程中合并后 的副本再进行合并处理， 然后再进行校验处理。
如果基站没有正确接收该数据包， 主中继站正确接收该数据包， 则 基站为该数据包分配资源给主中继站进行重传 （为简明起见， 图 8中未 示出主中继站重传的步骤）。 主中继站则在基站分配的资源上将进行该 数据包合并后的副本的第二次发送， 基站在接收到该合并后的副本之 后， 与第一次接收到的副本进行合并处理以得到一个合并后的数据包， 对合并后的数据包进行校验处理， 并将校验结果发送给主中继站。
优选地， 在基站没有正确接收该数据包， 主中继站正确接收该数据 包时， 在基站为该数据包分配资源给主中继站进行重传的同时， 基站还 可以分配资源给辅助中继站以进行重传。 第二次传输时， 基站在接收到 来自主中继站的数据包的一个合并后的副本以及来自辅助中继站的副 本之后， 可以仅对这两个副本进行合并处理后进行校验处理， 也可以对 这两个副本进行合并处理之后再与第一次传输过程中合并后的副本再 进行合并处理， 然后再进行校验处理。 并将校验结果发送给主中继站和 辅助中继站。 如此进行上述移动站或者主中继站以及辅助中继站重传的过程直 到基站正确接收或者重传次数达到系统预定最大值后放弃该数据包的 传输为止。
1.2 数据包的下行传输
下面以图 2所示的网络拓朴结构为例， 才 据附图 9对主动混合自动 重传中数据包的下行传输的过程进行详细描述。
首先， 在 B21中， 基站在其自身分配的传输资源上发送数据包给主 中继站与辅助中继站， 辅助中继站在接收到该数据包后， 在步骤 B22中 在基站分配的传输资源上将该数据包发送给主中继站。
主中继站在先后接收到所述数据包的来自移动站以及辅助中继站 的两个副本之后， 在步骤 B23中将这两个副本进行合并处理， 获得该数 据包一个合并后的副本， 并对该合并后的副本进行校验， 以判断是否正 确接收该数据包。 具体的校验方式不限， 根据发送端采用的校验方式而 定， 目前常用的是循环冗余码校验。
对于主中继站中数据包的发送， 有两种处理方式： 一种是根据校验 结果决定是否将该数据包发送给移动站，即校验结果正确，则在步骤 B24 将该数据包合并后的副本发送给移动站， 如果不正确， 则不发送； 另一 种处理方式是不论校验结果对错， 在步骤 B24中将数据包合并后的副本 发送给移动站。
若主中继站数据包校验结果错误， 而不发送数据包合并后的副本给 移动站， 则主中继站在步骤 B28中发送一个指示本中继站数据包校 ^结 果错误接收指示消息发送给基站。 然后基站为该数据包分配资源进行重 传， 资源分配同数据包的第一次传输。
若主中继站将该数据包合并后的副本发送给移动站， 则移动站在接 收到该副本后， 在步骤 B25中对该副本进行校 ¾r。 优选地， 移动站还可 以接收辅助中继站在步骤 B22中发送的数据包的副本， 并将该数据包来 自主中继站的合并后的副本与来自辅助中继站的副本进行合并处理 , 以 获得合并后的数据包， 并对该合并后的数据包进行校验处理。 移动站在 步骤 B26中发送指示移动站数据包的校验结果的接收指示消息给主中继 站。 优选地， 移动站还可以将指示移动站数据包的校验结果的接收指示 消息发送给辅助中继站。
主中继站可以直接发送指示本主中继站的数据包校验结果的接收 指示消息给基站， 也可结合移动站的数据包验证结果来决定发送相应的 接收指示消息。 具体如下： 主中继站在接收到来自移动站的指示数据包 校验结果的接收指示消息后， 如果移动站的数据包校验结果正确或者主 中继站的数据包校验结果正确时， 则主中继站在步骤 B28中发送一个指 示本主中继站数据包校验结果正确的接收指示消息给基站 , 否则发送一 个指示本主中继站数据包校验结果错误的接收指示消息给基站。
同时， 在步骤 B27中， 主中继站将来自所述移动站的指示所述移动 站数据包校验结果的接收指示消息转发给基站。
这里需要说明的是， 步骤 B27与步骤 B28的执行不分先后。
上述过程完成了数据包的第一次传输以及数据包接收正确与否的 通知过程。
如果移动站中数据包的校验结果正确， 即移动站正确接收该数据 包， 则该数据包的传输就完成了。
如果移动站没有正确接收该数据包， 并且主中继站也没有正确接收 该数据包， 则基站为该数据包分配资源给移动站、 辅助中继站和主中继 站进行重传 （为简明起见， 图 9 中未示出移动站重传的步骤）， 其重传 过程可以与图 9所述的步骤相同， 也可以稍有不同。 在第二次传输过程 中， 主中继站接收到数据包来自基站和在辅助中继站的两个副本之后 , 可以仅对这两个副本进行合并处理后进行校验处理， 也可以对这两个副 本进行合并处理之后再与第一次传输过程中合并后的副本再进行合并 处理， 然后再进行校验处理。 同样， 在第二次传输过程中， 移动站在接 收到来自主中继站的数据包的一个合并后的副本后， 可以与第一次数据 传输过程中的所接收的合并后的副本合并之后再进行校验； 或者移动站 在接收到来自主中继站的数据包的一个合并后的副本以及来自辅助中 继站的副本之后， 可以仅对这两个副本进行合并处理后进行校验处理， 也可以对这两个副本进行合并处理之后再与第一次传输过程中合并后 的副本再进行合并处理， 然后再进行校验处理， 并发送指示移动站数据 包校验结果的接收指示消息给主中继站， 再由主中继站转发给基站。
如果移动站没有正确接收该数据包， 主中继站正确接收该数据包， 则基站为该数据包分配资源给主中继站进行重传 （为简明起见， 图 9中 未示出主中继站重传的步骤）。 主中继站则在基站分配的资源上将进行 该数据包合并后的副本的第二次发送， 移动站在接收到该合并后的副本 之后， 与第一次接收到的副本进行合并处理以得到一个合并后的数据部 奥， 对合并后的数据包进行校验处理， 并发送指示移动站数据包校验结 果的接收指示消息给主中继站， 再由主中继站转发给基站。
优选地， 在移动站没有正确接收该数据包， 主中继站正确接收该数 据包时， 在基站为该数据包分配资源给主中继站进行重传的同时， 基站 还可以分配资源给辅助中继站以重传该数据包至移动站。 第二次传输 时， 移动站在接收到来自主中继站的数据包的一个合并后的副本以及来 自辅助中继站的副本之后， 可以仅对这两个副本进行合并处理后进行校 验处理， 也可以对这两个副本进行合并处理之后再与第一次传输过程中 合并后的副本再进行合并处理， 然后再进行校验处理， 并发送指示移动 站数据包校验结果的接收指示消息给主中继站， 再由主中继站转发给基 站。
如此进行上述基站或者主中继站以及辅助中继站重传的过程直到 移动站正确接收或者重传次数达到系统预定最大值后放弃该数据包的 传输为止。
2. 被动混合自动重传
根据本发明的具体实施例， 被动混合自动重传的特征在于主中继站 在接收到来自源网络设备的数据包经由多个不同传输路径的多个副本 后， 对多个副本进行合并处理之后得到一个合并后的副本， 直接将该合 并后的副本发送给目的网络设备。 这里源网络设备包括移动站或中继 站， 目的网络设备包括基站或中继站； 或者源网络设备包括基站， 目 的网络设备包括移动站。
2.1 数据包的上行传输 下面以图 2所示的网络拓朴结构为例， 根据附图 10对被动混合自 动重传中数据包的上行传输的过程进行详细描述。
首先， 在步骤 C11中， 移动站在基站分配的传输资源上发送数据包 给主中继站与辅助中继站，辅助中继站在接收到该数据包后，在步骤 C 12 中在基站分配的传输资源上将该数据包发送给主中继站。
主中继站在先后接收到所述数据包的来自移动站以及辅助中继站 的两个副本之后， 在步骤 C13中将这两个副本进行合并处理， 获得该数 据包一个合并后的副本。 然后， 在步骤 C14中将该数据包合并后的副本 发送给基站。
基站在接收到所述合并后的副本后， 在步骤 C15中对该副本进行校 验。 优选地， 基站还可以接收辅助中继站在步骤 C12中发送的数据包的 副本， 并将该数据包来自主中继站的合并后的副本与来自辅助中继站的 副本进行合并处理， 以获得合并后的数据包， 并对该合并后的数据包进 行校验处理。 在步骤 C16中， 基站发送指示基站数据包的校验结果的接 收指示消息给主中继站。 主中继站在接收到来自基站的指示数据包校验 结果的接收指示消息后，在步骤 C 17中将该接收指示消息转发给移动站。
上述过程完成了数据包的第一次传输以及数据包接收正确与否的 通知过程。
如果基站中数据包的校验结果正确， 即基站正确接收该数据包， 则 该数据包的传输就完成了。
如果基站没有正确接收该数据包， 则基站为该数据包分配资源给移 动站、 辅助中继站和主中继站进行重传， 其重传过程同上述步骤（为简 明起见， 图 10 中未示出移动站重传的步骤）。 重传的过程可以同图 10 中所示的步骤完全相同， 也可以稍有不同。 在第二次传输过程中， 主中 继站接收到数据包来自移动站和来自辅助中继站的两个副本之后， 可以 仅对这两个副本进行合并处理后发送给基站， 也可以对这两个副本进行 合并处理之后再与第一次传输过程中合并后的副本再进行合并处理 , 然 后再发送给基站。 同样， 在第二次传输过程中， 基站在接收到来自主中 继站的数据包的一个合并后的副本后， 可以与第一次数据传输过程中的 所接收的合并后的副本合并之后再进行校验； 或者基站在接收到来自主 中继站的数据包的一个合并后的副本以及来自辅助中继站的副本之后， 可以仅对这两个副本进行合并处理后进行校睑处理， 也可以对这两个副 本进行合并处理之后再与第一次传输过程中合并后的副本再进行合并 处理， 然后再进行校验处理。
优选地， 在图 10 所示的数据包第一次传输过程中， 主中继站在接 收到来自基站的指示数据包校验结果的接收指示消息后， 如果该接收指 示消息指示基站校验结果正确， 则主中继站将该接收指示消息转发给移 动站。 如果该接收指示消息指示基站校验结果错误， 则主中继站判断本 主中继站中该数据包校验结果是否正确。 如果在本主中继站中数据包校 验结果正确， 则将指示基站校验结果错误的接收指示消息改为指示基站 数据包校验结果正确的接收指示消息， 再发送给移动站。 这样， 就使得 移动站以为基站接收正确， 而不必对该数据包进行重传， 主中继站以及 辅助中继站进行该数据包的重传即可。
如此进行上述移动站或者主中继站以及辅助中继站重传的过程直 到基站正确接收或者重传次数达到系统预定最大值后放弃该数据包的 传输为止。
2.2 数据包的下行传输
下面以图 2所示的网络拓朴结构为例， 居附图 11对被动混合自动 重传中数据包的下行传输过程的过程进行详细描述。
首先， 在步骤 C21中， 基站在其自身分配的传输资源上发送数据包 给主中继站与辅助中继站，辅助中继站在接收到该数据包后，在步骤 C22 中在基站分配的传输资源上将该数据包发送给主中继站。
主中继站在先后接收到所述数据包的来自移动站以及辅助中继站 的两个副本之后， 在步骤 C23中将这两个副本进行合并处理， 获得该数 据包一个合并后的副本。 然后， 在步骤 C24中， 将数据包合并后的副本 发送给移动站。
移动站在接收到该副本后， 在步骤 C25中对该副本进行校验。 优选 地， 移动站还可以接收辅助中继站在步骤 C22中发送的数据包的副本， 并将该数据包来自主中继站的合并后的副本与来自辅助中继站的副本 进行合并处理， 以获得合并后的数据包， 并对该合并后的数据包进行校 验处理。 移动站在步骤 C26中发送指示移动站数据包的校验结果的接收 指示消息给主中继站。主中继站在步骤 C27中将该接收指示消息转发给 基站。
上述过程完成了数据包的第一次传输以及数据包接收正确与否的 通知过程。
如果移动站中数据包的校验结果正确， 即移动站正确接收该数据 包， 则该数据包的传输就完成了。
如果移动站没有正确接收该数据包， 则基站为该数据包分配资源其 自身、 辅助中继站和主中继站进行重传， 其重传过程同上述步骤（为简 明起见， 图 11 中未示出移动站重传的步骤）。 重传的过程可以同图 11 中所示的步骤完全相同， 也可以稍有不同。 在第二次传输过程中， 主中 继站接收到数据包来自基站和在辅助中继站的两个副本之后， 可以仅对 这两个副本进行合并处理后发送给移动站， 也可以对这两个副本进行合 并处理之后再与第一次传输过程中合并后的副本再进行合并处理， 然后 再发送给移动站。 同样， 在第二次传输过程中， 移动站在接收到来自主 中继站的数据包的一个合并后的副本后 , 可以与第一次数据传输过程中 的所接收的合并后的副本合并之后再进行校验； 或者移动站在接收到来 自主中继站的数据包的一个合并后的副本以及来自辅助中继站的副本 之后， 可以仅对这两个副本进行合并处理后进行校验处理， 也可以对这 两个副本进行合并处理之后再与第一次传输过程中合并后的副本再进 行合并处理， 然后再进行校验处理， 并发送指示移动站数据包校验结果 的接收指示消息给主中继站， 再由主中继站转发给基站。
如此进行上述基站或者主中继站以及辅助中继站重传的过程直到 移动站正确接收或者重传次数达到系统预定最大值后放弃该数据包的 传输为止。
以上从系统方法流程的角度对本发明的具体实施例进行了详细描 述， 需要说明的是， 上述具体实施例中的各个方法步骤是从功能的角度 来进行描述的， 实际实施时， 可能会根据无线通信网络的数据链路层以 及物理层的协议不同以及上下行子帧的调度不同， 各个步骤的执行的先 后会稍有变化。
下面结合图 12至图 16从主中继站以及基站角度对本发明的实施例 进行详细的 4 述。
图 12示出了 居本发明的一个具体实施方式在无线通信网络的主 中继站中用于数据传输的方法流程图。
首先， 在步骤 S 101 中， 主中继站接收来自源网络设备的数据包 经由多个不同的传输路径的多个副本； 然后， 在步骤 S102 中， 主中 继站将所述数据包的多个副本进行联合处理， 并将处理结果发送给相 应网络设备。 这里步骤 S101 又可详细分为以下两个子步骤 （为简明 起见， 图 12中未示出该步骤）： 首先， 主中继站接收来自所述源网絡 设备的所述数据包由该源网络设备直接发送的一个副本； 然后， 主中 继站接收来自所述源网络设备的所述数据包由所述一个或多个辅助 中继站发送的一个或多个副本。
这里源网络设备与目的网络设备包括以下各对网络设备中的任 一对： 移动站与基站、 移动站与中继站、 中继站与移动站、 中继站与 中继站、 中继站与基站、 基站与移动站、 基站与中继站。
如果是数据包的单次传输， 则所述步骤 S102具体为： 将数据包 的多个副本进行合并处理， 以得到一个合并后的副本， 并将合并后的 副本发送给目的网络设备。
在混合自动重传中， 如果主中继站或者目的网络设备接收错误的 话， 基站还会分配传输资源给源网络设备以进行数据包的重传。 优选 地， 在所述步骤 S101 之前， 还包括以下步骤： 主中继站接收来自所 述基站的用于指示所述源网络设备重传所述数据包的重传指示消息。 并且在重传时， 主中继站将重传接收的所述数据包的多个副本与之前 一次或多次传输的所述数据包的多个副本进行联合处理， 并将处理结 果发送给所述相应网络设备。 如果主中继站接收正确， 目的网络设备 接收错误， 基站还会分配传输资源给主中继站进行数据包的重传。 作 为一个变化的实施例， 基站还可以同时分配传输资源给主中继站与所 述一个或多个辅助中继站以进行该数据包的重传。
在被动混合重传中， 相应网络设备包括目的网络设备。 上述步骤
S 102具体又可以分为两个子步骤 S10211与 S10212, 如图 13所示。
首先， 在步骤 S10211 中， 主中继站将接收到的所述数据包的多 个副本进行合并处理， 以获得该数据包一个合并后的副本
然后， 在步骤 S10212 中， 将所述数据包合并后的副本发送给目 的网络设备。
在目的网络设备接收到该数据包合并后的副本后， 对该数据包进 行校验处理。 优选地， 目的网络设备还接收到所述数据包来自所述一 个或多个辅助中继站的一个或多个副本， 目的网络设备将该一个或多 个副本与来自主中继站的合并后的副本进行合并处理后， 得到一个合 并后的数据包， 然后对该数据包再进行校验处理， 并将发送指示校验 结果的接收指示消息给主中继站。
主中继站在接收到来自目的网络设备的用于指示该目的网络设 备是否正确接收该数据包的接收指示消息时， 将该接收指示消息发送 给所述源网络设备。
当源网络设备与目的网络设备为移动站与基站、 移动站与中继 站、 中继站与移动站、 中继站与中继站、 中继站与基站中的任一对时， 优选地， 主中继站在接收到来自目的网络设备的指示数据包校验结果的 接收指示消息后， 如果该接收指示消息指示目的网络设备校验结果正 确， 则主中继站将该接收指示消息转发给源网络设备。 如果该接收指示 消息指示目的网络设备校验结果错误， 则主中继站判断本主中继站中该 数据包校验结果是否正确。 如果在本主中继站中数据包校验结果正确， 则将指示目的网络设备校验结果错误的接收指示消息改为指示目的网 络设备数据包校验结果正确的接收指示消息， 再发送给源网络设备。 这 样， 就使得源网络设备以为目的网络设备接收正确， 而不必对该数据包 进行重传， 主中继站以及辅助中继站进行该数据包的重传即可。
在主动混合自动重传中， 相应网络设备包括源网络设备， 目的网 络设备和基站。 上述步骤 S102具体又可以分为四个子步骤 S10221、 SI 0222, S 10223与 S 10224, 如图 14所示。
首先， 在步骤 S10221 中， 主中继站将接收到的数据包的多个副 本进行合并处理， 以获得该数据包一个合并后的副本； 然后， 在步骤 S 10222 中， 对该数据包合并后的副本进行校验处理， 以获得一个校 验结果， 该校验结果指示主中继站是否正确接收所述数据包； 接着， 在步骤 S10223 中， 将校验结果发送给基站与源网络设备； 最后， 在 步骤 S 10224中， 将所述数据包合并后的副本发送给目的网络设备。 这里需要说明的是， 步骤 S10223与步骤 S10224的执行不分先后。 作 为一个变化的实施例，步骤 S10224的执行还可以根据步骤 S10222的 校验结果来进行。 即当步骤 S 10222 中数据包的校验结果指示主中继 站正确接收该数据包时， 主中继站才执行步骤 S 10224, 将所述数据 包合并后的副本发送给目的网络设备。
这里需要说明的是， 以上从功能的角度对主中继站的方法流程进 行了描述， 实际实施时， 可能会根据无线通信网络的数据链路层以及物 理层的协议不同以及上下行子帧的调度， 各个步骤执行的先后可能会稍 有变化。
在目前的无线通信网络中， 为了降低中继站以及移动站的复杂度 以及便于无线传输资源的集中管理与分配， 皆由基站来执行无线传输 资源的分配。 根据本发明的具体实施例， 基站为源网络设备、 主中继 站、 一个或多个辅助中继站以及目的网络设备分别分配传输资源， 以 使所述源网络设备在所分配的传输资源上将数据包的一个副本发送 给所述主中继站以及所述一个或多个辅助中继站， 所述一个或多个辅 助中继站在所分配的传输资源上将接收到的来自所述源网络设备的 所述数据包的副本发送给所述主中继站； 所述主中继站在接收到所述 数据包的多个副本之后， 进行联合处理， 并在所分配的传输资源上将 处理结果发送给相应网络设备。
优选地， 基站为源网络设备、 主中继站、 一个或多个辅助中继站 以及目的网络设备分别分配传输资源， 以使所述源网络设备在所分配 的传输资源上将数据包的一个副本发送给所述主中继站以及所述一 个或多个辅助中继站， 所述一个或多个辅助中继站在所分配的传输资 源上将接收到的来自所述源网络设备的所述数据包的副本发送给所 述主中继站与所述目的网络设备； 所述主中继站在接收到所述数据包 的多个副本之后， 进行联合处理， 并在所分配的传输资源上将处理结 果发送给相应网络设备。
这里源网络设备与目的网络设备包括以下各对网络设备中的任 一对： 移动站与基站、 移动站与中继站、 中继站与移动站、 中继站与 中继站、 中继站与基站、 基站与移动站、 基站与中继站。
图 15 示出了根据本发明的一个具体实施例的传输资源分配的一 个示意图， 为简单起见， 图 15 以例如图 2所示的包含一个辅助中继 站的网络拓朴结构为例，对于图 5至图 7所示的网络拓朴结构或者在 此基础上变形的网络拓朴结构， 本领域的技术人员根据本申请的教 导， 应知晓基站如何进行所述资源分配。
在每次为数据包传输分配传输资源时， 基站分配传输资源块 1给 源网络设备， 用于源网络设备发送数据包给主中继站以及辅助中继 站； 分配传输资源块 2给辅助中继站， 用于辅助中继站发送数据包给 主中继站以及目的网络设备； 分配传输资源块 3给主中继站， 用于主 中继站发送数据包给目的网络设备。 对上述 3个传输资源块的时间先 后的要求为： 传输资源块 1要早于传输资源块 2, 传输资源块 2早于 传输资源块 3。
需要说明的是， 由于同一个数据包的各个副本可以采用不同的调 制方式进行调制， 因此上述 3个传输资源块的大小可以不相同。
对于混合自动重传， 基站还要分配相应的传输资源块用于目的网 络设备以及主中继站发送指示数据包是否正确接收的接收指示消息。
在执行主动混合自动重传时， 基站还接收来自所述主中继站的用 于指示该主中继站是否正确接收来自所述源网络设备的所述数据包 的接收指示消息。 如果所述主中继站未正确接收来自所述源网络设备 的所述数据包， 则基站为源网络设备、 主中继站、 一个或多个辅助中 继站以及目的网络设备分配传输资源以进行数据包的重传， 重传的资 源分配同第一传输时的资源分配相同。
当主中继站正确接收来自源网絡设备的数据包时， 基站则根据来 目的网络设备的指示该目的网络设备数据包校验结果的接收指示消 息来判断目的网络设备是否正确接收该数据包， 当然， 如果基站即为 目的设备， 则无需接收该指示消息； 如果所述目的网络设备没有正确 接收该数据包， 则基站为所述主中继站以及所述一个或多个辅助中继 站分配传输资源以进行所述数据包的重传。
在执行被动混合自动重传时， 当目的设备为移动站或中继站时， 基站接收来自所述目的网络设备的用于指示该目的网络设备是否正 确接收来自所述源网络设备的所述数据包的接收指示消息。如果所述 目的网络设备没有正确接收来自所述源网络设备的所述数据包， 则基 站为重传分配资源， 重传的资源分配同第一次传输。
当基站为数据包传输的目的设备时， 基站还需执行如图 16所示 的处理流程图。
首先， 在步骤 S201 中， 基站接收由所述一个或多个辅助中继站 发送的所述数据包的一个或多个副本； 然后， 在步骤 S202 中， 基站 接收由所述主中继站发送的所述数据包经合并处理后的一个副本； 接 着， 基站在步骤 S203 中， 将接收到的由所述一个或多个辅助中继站 发送的所述数据包的一个或多个副本与接收到的由所述主中继站发 送的所述数据包经合并处理后的一个副本进行合并处理， 以获得一个 合并后的数据包； 在步骤 S204中， 对所述合并后的数据包进行校验， 以获得一个校验结果。 当所述合并后的数据包校验结果为错误时， 则 在步骤 S205中分配传输资源用于数据包的重传。
这里需要说明的是， 在数据包重传时， 在上述步骤 S202 中， 基 站还可将重传时接收到的的由所述一个或多个辅助中继站发送的所 述数据包的一个或多个副本与接收到的由所述主中继站发送的所述 数据包经合并处理后的一个副本进行合并处理后再与前面一次或多 次传输时所接收到的数据包多个副本合并后的副本进行合并处理。 具体地，在主动混合自动重传与被动混合自动重传中， 步骤 S205 中传输资源分配的具体流程又不相同。
在主动混合自动重传时， 当基站中数据包校验结果为错误时， 如 果主中继站的数据包校验结果也是错误， 则基站为源网络设备、 主中 继站、 一个或多个辅助中继站以及目的网络设备分配传输资源以进行 数据包的重传， 重传的资源分配同第一传输时的资源分配相同； 如果 主中继站数据包校验结果正确， 则基站为主中继站、 一个或多个辅助 中继站以及目的网络设备分配传输资源以进行数据包的重传， 或者仅 为主中继站分配传输资源以进行数据包的重传。
在被动混合自动重传时， 当基站中数据包校验结果为错误时， 则 基站为源网络设备、 主中继站、 一个或多个辅助中继站以及目的网络 设备分配传输资源以进行数据包的重传， 重传的资源分配同第一传输 时的资源分配相同。
图 17 示出了根据本发明的一个具体实施方式在无线通信网络的 主中继站中用于数据传输的传输装置的结构框图。 该传输装置 10 包 括第一接收装置 11、 联合处理发送装置 12、 第二接收装置 13、 第二 发送装置 15和第三接收装置 14。其中，联合处理发送装置 12还包括 第一合并装置 121、 第一校验装置 122、 第一发送装置 123和第三发 送装置 124。 为简明起见， 该传输装置 10包括了很多优选实施例中所 包含的子装置， 本领域技术人员根据本申请的教导， 应能理解其中仅 第一接收装置 11 和联合处理发送装置 12是实施本发明所必要的装 置， 其他子装置为可选装置。
首先， 第一接收装置 11 接收来自源网络设备的数据包经由多个 不同的传输路径的多个副本， 即接收来自所述源网絡设备的所述数据 包由该源网络设备直接发送的一个副本以及接收来自所述源网络设 备的所述数据包由所述一个或多个辅助中继站发送的一个或多个副 本。
然后， 联合处理发送装置 12将所述数据包的多个副本进行联合 处理， 并将处理结果发送给相应网络设备。 这里源网络设备与目的网络设备包括以下各对网络设备中的任 一对： 移动站与基站、 移动站与中继站、 中继站与移动站、 中继站与 中继站、 中继站与基站、 基站与移动站、 基站与中继站。
如果是数据包的单次传输， 则联合处理发送装置 12的操作又可 具体由两个子装置第一合并装置 121和第一发送装置 123来执行。 第 一合并装置 121将数据包的多个副本进行合并处理， 以得到一个合并 后的副本， 然后， 第一发送装置 123将合并后的副本发送给目的网络 设备。
在混合自动重传中， 如果主中继站或者目的网络设备接收错误的 话， 基站还会分配传输资源给源网络设备以进行数据包的重传。 优选 地， 第二接收装置 13接收来自所述基站的用于指示所述源网络设备 重传所述数据包的重传指示消息， 第一接收装置 1 1 根据第一接收装 置 13接收到的重传指示消息以及基站分配的传输资源信息在相应的 传输资源上重新接收该数据包。 并且在重传时，联合处理发送装置 12 将重传接收的所述数据包的多个副本与之前一次或多次传输的所述 数据包的多个副本进行联合处理， 并将处理结果发送给所述相应网络 设备。 如果主中继站接收正确， 目的网络设备接收错误， 基站还会分 配传输资源给主中继站的第一发送装置 123进行数据包的重传。 作为 一个变化的实施例， 基站还可以同时分配传输资源给主中继站与所述 一个或多个辅助中继站以进行该数据包的重传。
在被动混合重传中， 相应网络设备包括目的网络设备。 联合处理 发送装置 12的操作又可具体由两个子装置第一合并装置 121和第一 发送装置 123来执行。 第一合并装置 121将数据包的多个副本进行合 并处理， 以得到一个合并后的副本， 然后， 第一发送装置 123将合并 后的副本发送给目的网络设备。
在目的网络设备接收到该数据包合并后的副本后， 对该数据包进 行校验处理。 优选地， 目的网络设备还接收到所述数据包来自所述一 个或多个辅助中继站的一个或多个副本， 目的网络设备将该一个或多 个副本与来自主中继站的合并后的副本进行合并处理后， 得到一个合 并后的数据包， 然后对该数据包再进行校验处理， 并将发送指示校验 结果的接收指示消息给主中继站。
第三接收装置 14接收到来自目的网络设备的用于指示该目的网 络设备是否正确接收该数据包的接收指示消息， 然后由第二发送装置 15将该接收指示消息发送给所述源网络设备。
当源网络设备与目的网络设备为移动站与基站、 移动站与中继 站、 中继站与移动站、 中继站与中继站、 中继站与基站中的任一对时， 优选地， 第三接收装置 14在接收到来自目的网络设备的指示数据包校 验结果的接收指示消息后 , 如果该接收指示消息指示目的网络设备校验 结果正确， 则第二发送装置 15将该接收指示消息转发给源网络设备。 如果该接收指示消息指示目的网络设备校验结果错误， 则主中继站判断 本主中继站中该数据包校验结果是否正确。 如果在本主中继站中数据包 校验结果正确， 则将指示目的网络设备校验结果错误的接收指示消息改 为指示目的网络设备数据包校验结果正确的接收指示消息， 再由第二发 送装置 15发送给源网络设备。 这样， 就使得源网络设备以为目的网络 设备接收正确， 而不必对该数据包进行重传， 主中继站以及辅助中继站 进行该数据包的重传即可。
在主动混合自动重传中， 相应网络设备包括源网络设备， 目的网 络设备和基站。 则联合处理发送装置 12的操作又可具体由四个子装 置第一合并装置 121、 第一校验装置 122、 第一发送装置 123和第三 发送装置 124来执行。 第一合并装置 121将数据包的多个副本进行合 并处理， 以得到一个合并后的副本， 然后第一校验装置 122对该数据 包合并后的副本进行校验处理， 以获得一个校验结果， 该校验结果指 示主中继站是否正确接收所述数据包； 最后， 第三发送装置 124将校 验结果发送给基站与源网络设备， 并且第一发送装置 123将数据包合 并后的副本发送给目的网络设备。 这里需要说明的是， 第三发送装置 124与第一发送装置 123的发送操作不分先后。 作为一个变化的实施 例， 第三发送装置 124的发送操作还可以根据第一校验装置 122的校 验结果来进行。 即当第一校验装置 122的校验结果指示主中继站正确 接收该数据包时， 第三发送装置 124才将所述数据包合并后的副本发 送给目的网络设备。
这里需要说明的是， 以上从功能的角度对传输装置 10 的各个装 置的操作步骤进行了描述， 实际实施时，可能会根据无线通信网络的数 据链路层以及物理层的协议不同以及上下行子帧的调度， 各个装置的操 作步骤的先后可能会稍有变化。
图 18示出了根据本发明的一个具体实施方式在无线通信网络的 基站中用于为数据传输分配资源的资源分配装置的结构框图。 该资源 分配装置 20包括分配装置 21、 第四接收装置 22、 判断装置 23、 第五 接收装置 24、 第六接收装置 25、 第二合并装置 26以及第二校验装置 27。 为简明起见， 该资源分配装置 20 包括了很多优选实施例中所包 含的子装置， 本领域技术人员根据本申请的教导， 应能理解其中仅分 配装置 21是实施本发明所必要的装置， 其他子装置为可选装置。
根据本发明的具体实施例， 分配装置 21 为源网络设备、 主中继 站、 一个或多个辅助中继站以及目的网络设备分别分配传输资源， 以 使所述源网络设备在所分配的传输资源上将数据包的一个副本发送 给所述主中继站以及所述一个或多个辅助中继站， 所述一个或多个辅 助中继站在所分配的传输资源上将接收到的来自所述源网络设备的 所述数据包的副本发送给所述主中继站； 所述主中继站在接收到所述 数据包的多个副本之后， 进行联合处理， 并在所分配的传输资源上将 处理结果发送给相应网络设备。
优选地， 分配装置 21 为源网络设备、 主中继站、 一个或多个辅 助中继站以及目的网络设备分别分配传输资源， 以使所述源网络设备 在所分配的传输资源上将数据包的一个副本发送给所述主中继站以 及所述一个或多个辅助中继站， 所述一个或多个辅助中继站在所分配 发送给所述主中继站与所述目的网络设备； 所述主中继站在接收到所 述数据包的多个副本之后， 进行联合处理， 并在所分配的传输资源上 将处理结果发送给相应网络设备。 分配装置 21 所分配的传输资源的在时间上的先后关系要求可参 看图 15。
这里源网络设备与目的网络设备包括以下各对网络设备中的任 一对： 移动站与基站、 移动站与中继站、 中继站与移动站、 中继站与 中继站、 中继站与基站、 基站与移动站、 基站与中继站。
在执行主动混合自动重传时， 第四接收装置 22还接收来自所述 主中继站的用于指示该主中继站是否正确接收来自所述源网络设备 的所述数据包的接收指示消息。 如果所述主中继站未正确接收来自所 述源网络设备的所述数据包， 则分配装置 21 为源网络设备、 主中继 据包的重传， 重传的资源分配同第一传输时的资源分配相同。
当主中继站正确接收来自源网络设备的数据包时， 分配装置 21 则根据第五接收装置 24接收的来目的网络设备的指示该目的网络设 备数据包校验结果的接收指示消息来判断目的网络设备是否正确接 收该数据包， 当然， 如果基站即为目的设备， 则第五接收装置 24无 需接收该指示消息； 如果所述目的网络设备没有正确接收该数据包， 则分配装置 21 为所述主中继站以及所述一个或多个辅助中继站分配 传输资源以进行所述数据包的重传。
在执行被动混合自动重传时， 当目的设备为移动站或中继站时， 第五接收装置 24接收来自所述目的网络设备的用于指示该目的网络 设备是否正确接收来自所述源网络设备的所述数据包的接收指示消 息。 如果所述目的网络设备没有正确接收来自所述源网络设备的所述 数据包， 则分配装置 21 为重传分配资源， 重传的资源分配同第一次 传输。
当基站为数据包传输的目的设备时，还需由第六接收装置 25、 第 二合并装置 26以及第二校验装置 27执行如下的操作过程。
首先， 第六接收装置 25接收由所述一个或多个辅助中继站发送 的所述数据包的一个或多个副本； 并接收由所述主中继站发送的所述 数据包经合并处理后的一个副本； 接着， 第二合并装置 26将接收到 的由所述一个或多个辅助中继站发送的所述数据包的一个或多个副 本与接收到的由所述主中继站发送的所述数据包经合并处理后的一 个副本进行合并处理， 以获得一个合并后的数据包； 第二校验装置 27 对所述合并后的数据包进行校验， 以获得一个校验结果。 当所述合并 后的数据包校验结果为错误时， 则分配装置 21 分配传输资源用于数 据包的重传。
这里需要说明的是， 在数据包重传时， 第二合并装置 26还可将 重传时接收到的由所述一个或多个辅助中继站发送的所述数据包的 一个或多个副本与接收到的由所述主中继站发送的所述数据包经合 并处理后的一个副本进行合并处理后再与前面一次或多次传输时所 接收到的数据包多个副本合并后的副本进行合并处理。
具体地， 在主动混合自动重传与被动混合自动重传中， 分配装置 21执行的传输资源分配情形不相同。
在主动混合自动重传时， 当基站中数据包校验结果为错误时， 如 果主中继站的数据包校验结果也是错误， 则分配装置 21 为源网络设 备、 主中继站、 一个或多个辅助中继站以及目的网络设备分配传输资 源以进行数据包的重传， 重传的资源分配同第一传输时的资源分配相 同； 如果主中继站数据包校验结果正确， 则分配装置 21为主中继站、 包的重传， 或者分配装置 21 仅为主中继站分配传输资源以进行数据 包的重传。
在被动混合自动重传时， 当基站中数据包校验结果为错误时， 则 分配装置 21 为源网络设备、 主中继站、 一个或多个辅助中继站以及 目的网络设备分配传输资源以进行数据包的重传， 重传的资源分配同 第一传输时的资源分配相同。
以上对本发明的具体实施例进行了描述。 需要理解的是， 本发明并 不局限于上述特定实施方式， 本领域技术人员可以在所附权利要求的范 围内做出各种变形或修改。
