为了使本发明的目的、 技术方案和优点更加清楚, 下面将结合附图对本 发明作进一步地详细描述, 显然, 所描述的实施例仅仅是本发明一部份实施 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前提下所获得的所有其它实施例, 都属于本发明保护的 范围。
下面以图 1为例详细说明本发明实施例一提供的一种训练资源分配方法, 图 1 为本发明实施例一提供的一种训练资源分配方法的流程示意图。 该训练 资源分配方法的执行主体为网络设备, 该网络设备可以具体为基站, 光网络 终端等设备。 如图 1所示, 该训练资源分配方法包括以下步骤:
步骤 S101 , 为资源分配周期内的一个频段划分训练资源块。
网络设备在信道训练阶段中的每个资源分配周期内, 为每个频段划分相 应的训练资源块, 以便对在某一资源分配周期内使用某一频段的用户设备进 行上行信道训练。
训练资源块的划分原则具体的为: 将资源分配周期内的至少一个连续的 时域符号按照频段的宽度划分为至少一个资源块, 至少一个资源块中的每个 资源块为该资源块所在频段的训练资源块。
优选地, 至少一个连续的时域符号在资源分配周期的最开始的部分。 如图 2所示, 图 2 中的方块为一个资源分配周期内所有的时频资源。 其 中, 每一个方格代表时频资源上最小粒度的资源块, 即一个方格宽度为一个 时域符号, 高度为频段的宽度。 在该资源分配周期内网络设备可任意将至少 一个连续的时域符号按照频段的宽度划分为至少一个训练资源块。 优选地, 至少一个连续的时域符号在资源分配周期的最开始的部分, 如图 2 的阴影部 分所示, 在该资源分配周期内, 将两个连续的时域符号按照频段的宽度划分 为多个资源块, 每行的连续的两个阴影资源块即为其所在频段的训练资源块。 步骤 S 1 02 , 将已分配在所述频段上的上行数据时频资源所对应的用户设 在每个资源分配周期内, 一个频段可能会在不同时间段被不同的用户设 备占用, 那么在该资源分配周期内在不同时间段占用同一频段的用户设备都 具有占用该频段的训练资源块的资格。 用户设备是否在某一时间段占用某一 频段, 可根据在该频段上已分配的上行数据时频资源进行确定, 因此网络设 备将已分配在该频段上的上行数据时频资源所对应的用户设备确定为具有占 用训练资源块的资格的用户设备。
步骤 S 1 03 , 根据在所述资源分配周期内用户设备占用所述频段的时间长 一个, 从具有占用所述训练资源块的资格的用户设备中确定占用训练资源块 的用户设备, 将训练资源块分配给该用户设备。
可选地, 将该频段的训练资源块分配给具有占用训练资源块的资格的用 户设备中在资源分配周期内占用该频段时间最长的用户设备。
若在资源分配周期内具有占用训练资源块的资格的用户设备占用该频段 的时间相同, 则将该频段的训练资源块分配给具有占用训练资源块的资格的 用户设备中距离前一次在该频段上占用训练资源块时间最长的用户设备。
需要说明的是, 用户设备前一次在该频段上占用的训练资源块为在至少 前一个资源分配周期内分配的训练资源块。 每个资源分配周期都会重新分配 训练资源块, 因此用户设备前一次在该频段上占用的训练资源块与当前资源 分配周期分配的训练资源块不同。
在一个具体的例子中, 如图 3 所示, 每一行为一个频段。 从第一行频段 可以看出,在资源分配周期内,第一行频段在不同的时间段分别被用户设备 1 , 用户设备 2 , 用户设备 3 , 用户设备 4和用户设备 5 占用, 因此用户设备 1 , 用户设备 2 , 用户设备 3 , 用户设备 4和用户设备 5都具有占用该频段训练资 源块的资格。 用户设备 2 在该资源分配周期内占用该频段的时间最长, 因此 将第一行频段的训练资源块分配给用户设备 2。从第三行频段可以看出, 在资 源分配周期内, 第三行频段在不同的时间段分别被用户设备 2 , 用户设备 3和 用户设备 4占用, 因此用户设备 2 , 用户设备 3和用户设备 4都具有占用该频 段训练资源块的资格。 由于用户设备 2 , 用户设备 3和用户设备 4在该资源分 配周期内占用该频段的时间相同, 因此将第三行频段的训练资源块分配给用 户设备 2 ,用户设备 3和用户设备 4中距离前一次在第三行频段上占用训练资 源块时间最长的用户设备。 其它行频段按照相同的方式分配每个频段的训练 资源块。
需要说明的是, 虽然图 3 未能体现出用户设备距离前一次在其所在频段 上占用训练资源块的时间, 但网络设备可根据之前的训练资源块分配记录获 知距离前一次在其所在频段上占用训练资源块时间最长的用户设备。 间的长短, 仅按照具有占用所述训练资源块的资格的用户设备距离前一次在 其所在频段上占用训练资源块的时间分配训练资源块。
将该频段的训练资源块分配给具有占用训练资源块的资格的用户设备中 距离前一次在该频段上占用训练资源块时间最长的用户设备。
但是, 当具有占用所述训练资源块的资格的用户设备距离前一次在该频 段上占用训练资源块时间相同时, 可将训练资源块分配给具有占用所述训练 资源块的资格的用户设备中在资源分配周期内占用所述频段时间最长的用户 设备。
可选地, 还可以将具有占用训练资源块的资格的用户设备占用频段时间 的长短和距离前一次在该频段上占用训练资源块的时间的长短进行综合考 虑。
具体的, 确定具有占用所述训练资源块的资格的用户设备中的每个用户 设备在资源分配周期内的占用时间是否超出预先设定的第一时间阈值, 并确 定具有占用所述训练资源块的资格的用户设备中的每个用户设备距离前一次 在该频段上占用训练资源块的时间是否超出预先设定的第二时间阈值; 若具 有占用训练资源块的资格的用户设备中包括在资源分配周期内的占用频段时 间超出第一时间阈值的用户设备, 且不包括距离前一次在该频段上占用训练 资源块的时间超出第二时间阈值的用户设备时, 将训练资源块分配给具有占 用训练资源块的资格的用户设备中在资源分配周期内占用频段时间最长的用 户设备; 若具有占用训练资源块的资格的用户设备中包括距离前一次在该频 段上占用训练资源块的时间超出第二时间阈值的用户设备, 且不包括在资源 分配周期内的占用频段时间超出第一时间阈值的用户设备时, 将训练资源块 分配给具有占用训练资源块的资格的用户设备中距离前一次在该频段上占用 训练资源块时间最长的用户设备; 若具有占用训练资源块的资格的用户设备 中不包括在资源分配周期内占用频段时间超过第一时间阈值的用户设备, 且 不包括距离前一次在该频段上占用训练资源块的时间超出第二时间阈值的用 户设备时, 或具有占用训练资源块的资格的用户设备中既包括在资源分配周 期内占用频段时间超过第一时间阈值的用户设备, 也包括距离前一次在该频 段上占用训练资源块的时间超出第二时间阈值的用户设备时, 将训练资源块 分配给具有占用训练资源块的资格的用户设备中在资源分配周期内占用频段 时间最长的用户设备, 在资源分配周期内具有占用训练资源块的资格的用户 设备占用频段的时间相同时, 将该频段的训练资源块分配给具有占用训练资 源块的资格的用户设备中距离前一次在该频段上占用训练资源块时间最长的 用户设备, 或分配给具有占用训练资源块的资格的用户设备中距离前一次在 该频段上占用训练资源块时间最长的用户设备, 当具有占用所述训练资源块 的资格的用户设备距离前一次在该频段上占用训练资源块时间相同时, 可将 训练资源块分配给具有占用所述训练资源块的资格的用户设备中在资源分配 周期内占用所述频段时间最长的用户设备。
利用本发明实施例一提供的训练资源分配方法, 在每个资源分配周期内, 为每个频段划分训练资源块, 并根据频段上已分配的上行数据时频资源对应 的用户设备确定具有占用该训练资源块资格的用户设备, 然后将该训练资源 块分配给其中的用户设备。 由于该方法是在每个资源分配周期内, 为每个频 段划分训练资源块, 因此能够降低上行信道训练对其他在线用户的影响。 并 且能够有效的利用历史信息进行上行信道训练, 对使用当前频带的用户设备 进行该部分频段的上行信道训练。 由此可以看出, 该方法适用于点到多点的 系统, 并且可利用较少的时频资源实现准确的上行信道训练, 从而提高频谱 利用率。
下面以图 4 为例详细说明本发明实施例二提供的一种训练资源分配装 置, 图 4为本发明实施例二提供的一种训练资源分配装置的结构示意图。 该 训练资源分配装置应用于网络设备, 网络设备可以具体为基站, 光线路终端 等设备, 用以实现实施例一提供的训练资源分配方法。
如图 4所示, 该训练资源分配装置包括: 划分单元 2 1 0 , 确定单元 22 0 和分配单元 2 30。
划分单元 21 0用于为资源分配周期内的一个频段划分训练资源块。
划分单元 21 0在信道训练阶段中的每个资源分配周期内, 为每个频段划 分相应的训练资源块, 以便对在某一资源分配周期内使用某一频段的用户设 备进行上行信道训练。
划分单元 21 0具体用于将资源分配周期内的至少一个连续的时域符号按 照频段的宽度划分为至少一个资源块, 至少一个资源块中的每个资源块为该 资源块所在频段的训练资源块。
优选地, 该至少一个连续的时域符号在在资源分配周期的最开始部分。 确定单元 220用于将已分配在所述频段上的上行数据时频资源所对应的 在每个资源分配周期内, 一个频段可能会在不同时间段被不同的用户设 备占用, 那么在该资源分配周期内在不同时间段占用同一频段的用户设备都 具有占用该频段的训练资源块的资格。 用户设备是否在某一时间段占用某一 频段, 可根据在该频段上已分配的上行数据时频资源进行确定, 因此确定单 元 220将已分配在该频段上的上行数据时频资源所对应的用户设备确定为具 有占用训练资源块的资格的用户设备。
分配单元 230用于根据在所述资源分配周期内用户设备占用所述频段的 时间长短和用户设备距离前一次在所述频段上占用训练资源块的时间长短中 的至少一个, 从具有占用所述训练资源块的资格的用户设备中确定占用训练 资源块的用户设备, 将训练资源块分配给该用户设备。
可选地, 分配单元 2 30将该频段的训练资源块分配给具有占用训练资源 块的资格的用户设备中在资源分配周期内占用该频段时间最长的用户设备。
若在资源分配周期内具有占用训练资源块的资格的用户设备占用该 频段的时间相同, 分配单元 230将该频段的训练资源块分配给具有占用训 练资源块的资格的用户设备中距离前一次在该频段上占用训练资源块时间 最长的用户设备。
需要说明的是, 用户设备前一次在该频段上占用的训练资源块为在至少 前一个资源分配周期内分配的训练资源块。 每个资源分配周期都会重新分配 训练资源块, 因此用户设备前一次在该频段上占用的训练资源块与当前资源 分配周期分配的训练资源块不同。 间的长短, 分配单元 230仅按照具有占用所述训练资源块的资格的用户设备 距离前一次在其所在频段上占用训练资源块的时间分配训练资源块。
分配单元 230将该频段的训练资源块分配给具有占用训练资源块的资格 的用户设备中距离前一次在该频段上占用训练资源块时间最长的用户设备。
但是, 当具有占用所述训练资源块的资格的用户设备距离前一次在该频 段上占用训练资源块时间相同时, 分配单元 230可将训练资源块分配给具有 占用所述训练资源块的资格的用户设备中在资源分配周期内占用所述频段时 间最长的用户设备。
可选地, 还可以将具有占用训练资源块的资格的用户设备占用频段时间 的长短和距离前一次在该频段上占用训练资源块的时间的长短进行综合考 虑。
具体的, 分配单元 230确定具有占用所述训练资源块的资格的用户设备 中的每个用户设备在资源分配周期内的占用时间是否超出预先设定的第一时 间阈值, 并确定具有占用所述训练资源块的资格的用户设备中的每个用户设 备距离前一次在该频段上占用训练资源块的时间是否超出预先设定的第二时 间阈值; 若具有占用训练资源块的资格的用户设备中包括在资源分配周期内 的占用频段时间超出第一时间阈值的用户设备, 且不包括距离前一次在该频 段上占用训练资源块的时间超出第二时间阈值的用户设备时, 将训练资源块 分配给具有占用训练资源块的资格的用户设备中在资源分配周期内占用频段 时间最长的用户设备; 若具有占用训练资源块的资格的用户设备中包括距离 前一次在该频段上占用训练资源块的时间超出第二时间阈值的用户设备, 且 不包括在资源分配周期内的占用频段时间超出第一时间阈值的用户设备时, 将训练资源块分配给具有占用训练资源块的资格的用户设备中距离前一次在 该频段上占用训练资源块时间最长的用户设备; 若具有占用训练资源块的资 格的用户设备中不包括在资源分配周期内占用频段时间超过第一时间阈值的 用户设备, 且不包括距离前一次在该频段上占用训练资源块的时间超出第二 时间阈值的用户设备时, 或具有占用训练资源块的资格的用户设备中既包括 在资源分配周期内占用频段时间超过第一时间阈值的用户设备, 也包括距离 前一次在该频段上占用训练资源块的时间超出第二时间阈值的用户设备时, 将训练资源块分配给具有占用训练资源块的资格的用户设备中在资源分配周 期内占用频段时间最长的用户设备, 在资源分配周期内具有占用训练资源块 的资格的用户设备占用频段的时间相同时, 将该频段的训练资源块分配给具 有占用训练资源块的资格的用户设备中距离前一次在该频段上占用训练资源 块时间最长的用户设备, 或分配给具有占用训练资源块的资格的用户设备中 距离前一次在该频段上占用训练资源块时间最长的用户设备, 当具有占用所 述训练资源块的资格的用户设备距离上次分配训练资源块时间相同时, 可将 训练资源块分配给具有占用所述训练资源块的资格的用户设备中在资源分配 周期内占用所述频段时间最长的用户设备。
利用本发明实施例二提供的训练资源分配装置, 在每个资源分配周期内, 为每个频段划分训练资源块, 并根据频段上已分配的上行数据时频资源对应 的用户设备确定具有占用该训练资源块资格的用户设备, 然后将该训练资源 块分配给其中的用户设备。 由于该装置是在每个资源分配周期内, 为每个频 段划分训练资源块, 因此能够降低上行信道训练对其他在线用户的影响。 并 且能够有效的利用历史信息进行上行信道训练, 对使用当前频带的用户设备 进行该部分频段的上行信道训练。 由此可以看出, 该装置适用于点到多点的 系统, 并且可利用较少的时频资源实现准确的上行信道训练, 从而提高频谱 利用率。
在硬件实现上, 以上划分单元 210, 确定单元 220和分配单元 230可 以以硬件形式内嵌于或独立于网络设备的处理器中, 也可以以软件形式存 储于网络设备的存储器中, 以便于处理器调用执行以上各个模块对应的操 作。 该处理器可以为中央处理单元 (CPU ) 、 微处理器、 单片机等。

进一步地, 所述根据在所述资源分配周期内用户设备占用所述频段的时 间长短和用户设备距离前一次在所述频段上占用训练资源块的时间长短中的 至少一个, 从所述具有占用所述训练资源块的资格的用户设备中确定占用所 述训练资源块的用户设备具体为:
备距离前一次在所述频段上占用训练资源块的时间是否超出预先设定的第二 时间阈值; 若所述具有占用所述训练资源块的资格的用户设备中包括在所述 资源分配周期内的占用所述频段的时间超出所述第一时间阈值的用户设备, 且不包括距离前一次在所述频段上占用训练资源块的时间超出所述第二时间 阈值的用户设备时, 将所述训练资源块分配给所述具有占用所述训练资源块 的资格的用户设备中在所述资源分配周期内占用所述频段时间最长的用户设 备; 若所述具有占用所述训练资源块的资格的用户设备中包括距离前一次在 所述频段上占用训练资源块的时间超出所述第二时间阈值的用户设备, 且不 包括在所述资源分配周期内的占用所述频段的时间超出所述第一时间阈值的 用户设备时, 将所述训练资源块分配给所述具有占用所述训练资源块的资格 的用户设备中距离前一次在所述频段上占用训练资源块时间最长的用户设 备。
