背景技术 随着移动通信技术的发展, 协作多点( Coordina ted Mul t iple Po int s , CoMP )传输技术作为移动通信系统的关键技术, 也成为了一个重要课题。 在 CoMP技术中, 通过联合调度 ( Joint Schedul ing , JS ), 让每个时刻的 频带资源得到合理的利用, 提高系统的吞吐率和降低边缘用户的干扰,。
联合调度算法的设计主要以降低扇区间干扰为标准, 为了充分利用时 频资源和降低边缘用户的干扰, 让边缘用户和对自身干扰最小的用户占用 相同的时频资源。 传统的联合调度方法为: 对于同一时频资源, 计算各种 用户组合对应的比例公平(Propor t iona l ly Fa i r , PF )优先级, 并选择 PF 优先级最大的进行调度。 具体的, 假设一个基站下有三个扇区, i、 j、 k分 别代表每个扇区的任意一个用户, 则需要计算 i的传输速率, i在 j影响下 的传输速率、 i在 j和 k影响下的传输速率、 j的传输速率、 j在 i影响下 的传输速率、 j在 i和 k影响下的传输速率等等。 通过计算得到各个用户在 各种组合下的传输速率, 然后除以用户 i、 j或 k本身的平均传输速率, 最 终得到每个组合的 PF优先级。 选取其中最大 PF优先级的组合进行调度。
在实现上述联合调度的过程中, 发明人发现现有技术中至少存在如下 问题: 虽然能够提高系统的吞吐率和降低边缘用户的干扰, 但由于需要对 所有可能的用户组合计算 PF优先级, 而用户组合数量庞大, 计算过程过于 复杂, 导致计算成本较高和调度时延较大的问题。
发明内容 本发明的实施例提供一种联合调度方法及装置, 能够在提高系统的吞 吐率和降低边缘用户的干扰的基础上, 解决计算成本较高和调度时延较大 的问题。

一方面, 提供了一种基站, 包括联合调度装置。 本发明实施例提供的联合调度方法及装置, 通过判断待调度用户是否 为对其他用户干 4尤较大的 CoMP用户, 让 CoMP用户占用专门的 CoMP频带资 源, 可以避免了 CoMP用户与非 CoMP用户共用相同的频带资源, 从而可以 降低 CoMP用户对非 CoMP用户的干扰, 满足提高系统的吞吐率和降低边缘 用户的干扰的要求, 与现有技术中计算所有可能的用户组合对应的 PF优先 级的方法相比, 简化了计算过程, 解决了计算成本较高和调度时延较大的 问题。

其中, CoMP用户设备为满足 CoMP传输条件的用户设备, CoMP传输条 件可以通过设置计算公式或门限值等方式预先设定。 其中, CoMP传输条件 可以为: 用户设备所在扇区的参考信号接收功率(Reference S i gna l Rece iv ing Power , RSRP)与用户设备到用户设备所在扇区之外的扇区的 RSRP 的差值小于或等于预定门限值。 其中, RSRP可以从基站服务器上已有的用 户信息中获取。 若用户设备所在扇区的参考信号接收功率 RSRP与用户设备 到用户设备所在扇区之外的扇区的 RSRP的差值小于或等于预定门限值, 则 所述用户设备为 CoMP用户设备; 否则, 所述用户设备为非 CoMP用户设备。 通过以上规则选取的 CoMP用户设备主要分布在基站内边缘区域, 对其他用 户的干扰较大。 可以理解的是, 此处的预设门限值可以根据实际需要设定, 本发明实施例对此不做限定。
另外, 可以根据具体情况, 通过调整预定门限值的数值调整 CoMP用户 的限定范围。 CoMP用户的判断包括但不局限于以上方法, 也可以通过其他 参数、 算式或门限值实现 CoMP用户的判断, 本发明实施例不做限定。
102、若等待调度的用户设备有 CoMP用户设备,则调度等待调度的 CoMP 用户设备, 并根据调度的 CoMP用户设备所需频带资源大小, 将 CoMP频带 资源分配给所述调度的 CoMP用户设备, 其中所述 CoMP频带资源为从参与 联合调度的扇区的频带资源中划分出的部分频带资源, 用于让 CoMP用户设 备优先使用。 划分的 CoMP频带资源, 也可以在确定有等待调度的 CoMP用户设备后从参 与联合调度的扇区的频带资源中划分出 CoMP频带资源, 还可以为通过其他 确定规则确定的 CoMP频带资源, 对于具体的 CoMP频带资源的确定方法本 发明实施例这里不做限定。
本发明实施例提供的联合调度方法, 通过判断待调度用户是否为对其 他用户干 4尤较大的 CoMP用户, 让 CoMP用户占用专门的 CoMP频带资源, 可 以避免 CoMP用户与非 CoMP用户共用相同的频带资源, 从而可以降低 CoMP 用户对非 CoMP用户的干扰, 满足提高系统的吞吐率和降低边缘用户的干扰 的要求, 与现有技术中需要计算所有可能的用户组合对应的 PF优先级的方 法相比, 简化了计算过程, 解决了计算成本较高和调度时延较大的问题。
并且, 通过为 CoMP用户划分专门的频带资源, 使 CoMP用户与 CoMP用 户共同占用相同的频带的几率较大, 若同一频带中的各个用户设备干扰都 比较大, 在联合接收时可以增大干扰抑制增益, 从而可以提高 CoMP用户的 抗干扰能力, 也降低了先进接收机的实现成本。 提供了一种联合调度方法, 如图 2所示, 包括:
201、 确定参与第一类调度的扇区, 获取所述参与第一类调度的扇区中 各个等待调度的用户设备对应的 PF优先级。
其中, 在长期演进(Long Term Evo lut i on, LTE )、 高级长期演进(Long Term Evo lut ion-Advanced , LTE-A )等移动通信系统中, 可以不用重新计 算各个等待调度的用户设备对应的 PF优先级, 而可直接从基站服务器上已 有的用户设备信息中获取。
在本实施例中, 可以根据预定的扇区选取规则确定参与第一类调度的 扇区, 例如可以为选取特定的一个或多个扇区, 也可以为所有参与联合调 度的扇区。 具体地, 预定的扇区选取规则可以为: 按照等待调度的用户设 备数量从多到少的顺序, 从参与联合调度的扇区中选择等待调度的用户设 备数量较多的 3 个扇区。 并且, 该联合调度方法可以应用于基站内的联合 调度, 也可以应用于基站间的联合调度。 具体的, 当在基站内进行联合调 度时, 预定的扇区选取规则可以为从基站内的各个扇区中设定特定的一个 或多个扇区参与第一类调度。 当在基站间进行联合调度时, 预定的扇区选 取规则可以为从参与联合调度的扇区中选择特定的一个或多个扇区参与第 一类调度, 其中参与联合调度的扇区可以属于不同基站。 202、 对等待调度的用户设备进行第一类调度, 其中所述第一类调度为 按照 PF优先级从高到低的顺序对用户设备进行调度, 并且所述第一类调度 中被调度的用户设备不允许共用相同的频带资源。
可选的,步骤 201中 PF优先级的获取和步骤 202中第一类调度可以为: 根据基站和扇区的特性, 从所有扇区中选取特定的一个或多个扇区进行用 户设备的 PF优先级的获取和第一类调度。 步骤 201中用户设备的 PF优先 级的获取和步骤 202 中第一类调度也可以为: 获取所有扇区中等待调度的 用户设备对应的 PF优先级, 并进行第一类调度。
具体的, 以基站内联合调度为例, 第一类调度的方式可以为: 将基站 内所有等待调度的用户设备根据 PF优先级进行排序, 按照 PF优先级从高 到低的顺序依次调度用户设备, 直到本基站的各个频带均有已调度的用户 设备。 所有参与联合调度的扇区中等待调度的用户设备经过第一类调度后, 已调度的用户设备将可能分散分布在基站内的各个扇区中, 因此每个扇区 中有一部分频带资源被占用, 仍有一部分频带资源未被占用。
仍以基站内联合调度为例, 第一类调度的方法也可以为: 选取基站内 的一个特定扇区进行第一类调度, 则获取基站内特定的一个扇区中等待调 度的用户设备对应的 PF优先级, 按照 PF优先级从高到低的顺序依次调度 本扇区中的用户设备, 直到本扇区的各个频带均有已调度的用户设备。 经 过第一类调度后, 已调度的用户设备均分布在本扇区中, 本扇区的频带资 源已完全占用, 其他扇区的频带资源未被占用。
另外, 在进行基站间的联合调度时, 将不同基站中的各个扇区加入到 联合调度的算法中。 相同的, 第一类调度的方式也可以为: 从参与联合调 度的扇区中选取特定扇区进行第一类调度, 根据选取的特定扇区中所有等 待调度的用户设备的 PF优先级, 按照 PF优先级从高到低的顺序依次调度 用户设备, 直到选取的特定扇区中的各个频带均有已调度的用户设备。
在本实施例中, 将等待调度的用户设备按照 PF优先级从高到低的顺序 进行第一类调度, 并且第一类调度中被调度的每一个用户设备均不占用相 同的频带资源, 尽量占满所有的频带资源, 从而可以充分利用基站的频带 资源, 提高移动通信系统的平均吞吐率。
203、 判断参与联合调度的扇区中是否有等待调度的用户设备; 若参与 联合调度的扇区中有等待调度的用户设备, 则执行步骤 204 ; 若参与联合调 度的扇区中没有等待调度的用户设备, 则执行步骤 208。
其中, 经过步骤 202 第一类调度后, 若判断参与联合调度的扇区中没 有等待调度的用户设备, 则说明频带资源足以让已调度的用户设备分别在 不同的频带工作, 即每个频带中只有一个用户设备, 用户设备间的干扰较 少, 因此可以不用进行同一频带资源中用户设备的配合, 调度结束。 经过 第一类调度后, 若判断参与联合调度的扇区中有等待调度的用户设备, 则 可以进行进一步的调度, 将未调度的用户设备分配到对应的频带资源中, 与对应的频带资源中已调度的用户设备占用相同的频带资源。
204、 判断第一类调度中已调度的用户设备中是否有 CoMP用户设备; 若所述第一类调度中已调度的用户设备里有 CoMP 用户设备, 则执行步骤 205 ; 若所述第一类调度中已调度的用户设备里没有 CoMP用户设备, 则执 行步骤 206
205、 调度等待调度的 CoMP用户设备, 并让所述等待调度的 CoMP用户 设备与第一类调度中已调度的 CoMP用户设备共用相同的频带资源。
其中, 若所述第一类调度中已调度的用户设备里有 CoMP用户设备, 则 根据已调度的 CoMP用户设备确定 CoMP频带资源, 以便进一步选取 CoMP用 户设备进行调度并与已调度的 CoMP用户设备共用相同的频带, 即占用步骤 202中经过第一类调度后各扇区中未被占用的频带资源。当等待调度的用户 设备中有多个 CoMP用户设备时, 可以根据等待调度的 CoMP用户设备对应 的 PF优先级从高到低的顺序依次调度所述等待调度的 CoMP用户设备。
206、 将等待调度的用户设备按照 PF优先级从高到低的顺序进行调度。 其中, 因为判定用户设备是否是 CoMP用户设备时, 所釆用的 CoMP传 输条件可以根据实际情况调整。进一步地,可以将 CoMP传输条件放宽, 提 高第一类调度中等待调度的用户设备中 CoMP用户设备的比例, 将 CoMP传 输条件调整到能让第一类调度中至少有一个 CoMP用户设备, 避免第一类调 度中没有 CoMP用户设备的情况, 因此出现这种第一类调度中已调度的用户 设备里没有 CoMP用户设备的情况的概率较小。 若出现了所述第一类调度中 已调度的用户设备里没有 CoMP用户设备的情况, 说明 CoMP用户设备很少, 由 CoMP 用户设备造成的干扰也较少, 可以将等待调度的用户设备按照 PF 优先级从高到低的顺序进行调度。
另外, 若所述第一类调度中已调度的用户设备里没有 CoMP用户设备, 也可以选取等待调度的 CoMP用户设备进行调度,并让所述等待调度的 CoMP 用户设备占用预先划分的 CoMP频带资源。
207、 判断参与联合调度的扇区中是否有未占用的频带资源; 若所述扇 区有未占用的频带资源, 则执行步骤 203 ; 若所述扇区的所有频带资源均被 占用, 则执行步骤 208。
其中, 若所述扇区有未占用的频带资源, 则按照步骤 203-步骤 206的 方法, 继续选取对应的用户设备与这些频带中已调度的用户设备共用相同 的频带资源。 若所述扇区的所有频带资源均被占用, 即参与联合调度的扇 区的频带资源均被占用, 并且在各个频带中, 已选取了对应的用户设备进 行组合共同占用相同的频带资源, 从而结束调度。
208、 结束调度。
其中, 在没有等待调度的用户设备时, 或在没有未占用的频带资源时, 结束调度。
可选的, CoMP频带资源可以为通过已调度的 CoMP用户设备所占用的频 带资源, 也可以为预先划分的 CoMP频带资源。 在所述判断等待调度的用户 设备中是否有协作多点 CoMP用户设备之前, 从全部的频带资源中预先划分 出 CoMP频带资源, 用于让所述等待调度的 CoMP用户设备占用所述 CoMP频 带资源。 通过预先划分 CoMP频带资源的方法, 可以省去步骤 201-步骤 204 中的部分或全部步骤, 直接选取 CoMP用户设备占用预先划分的 CoMP频带 资源, 剩余的用户设备可以按照 PF优先级进行调度占用非 CoMP频带资源。 需要说明的是, 本发明实施例的应用不局限于基站内的联合调度, 在 进行基站间的联合调度时, 可以将不同基站中的各个扇区加入本发明实施 例的联合调度算法中, 扇区数量增加后的调度方法与基站内的联合调度方 法基本相同。
本发明实施例提供的联合调度方法, 通过判断待调度用户是否为对其 他用户干 4尤较大的 CoMP用户, 让 CoMP用户占用专门的 CoMP频带资源, 可 以避免了 CoMP用户与非 CoMP用户共用相同的频带资源,从而可以降低 CoMP 用户对非 CoMP用户的干扰, 满足提高系统的吞吐率和降低边缘用户的干扰 的要求, 与现有技术中需要计算所有可能的用户组合对应的 PF优先级的方 法相比, 简化了计算过程, 解决了计算成本较高和调度时延较大的问题。
并且, 通过为 CoMP用户划分专门的频带资源, 使 CoMP用户与 CoMP用 户共同占用相同的频带的几率较大, 若同一频带中的各个用户设备干扰都 比较大, 因此在联合接收时可以增大干扰抑制增益, 从而可以提高 CoMP用 户的抗干扰能力, 也降低了先进接收机的实现成本。
