Description

多点协作系统中的调度分配方法以及装置 技术领域
本发明涉及一种通信领域, 特别涉及一种多点协作系统中的调度分 配方法以及装置。 背景技术 增强的长期演进 (LTE-A, Long Term Evaluation Advanced) 系统在 传统同构网络的基础上引入低功率发送节点, 组成异构网络。 可以由宏 小区 (Macro Cell )、 毫微微蜂窝 (Femto Cell)、 微微蜂窝 (Pico Cell)、 远端无线头 (RRH, Remote Radio Head), 中继器 (Relay) 组成。
为了改善 LTE-A系统下的小区覆盖和用户体验, 提高系统的吞吐量 和用户的数据传输速率, 多点协作 (CoMP, Coordinated Multiple Points ) 技术已经被引入。 这种技术利用多个地理位置上分散的传输点对用户协 同传输数据, 增强小区边缘用户的性能, 改进了小区的覆盖, 提高了小 区边缘的吞吐量和系统的吞吐量, 提高了用户的性能体验。
CoMP 传输方案包括联合处理 (JP, Joint Processing ) 和合作调度 / 波束赋形 (CS/CB , Coordination Scheduling/Beamforming )。 前者表示同 时可以有多个传输点同时有给用户设备的发送数据, 在多个点中动态的 选择一个或多个传输点为用户设备发送数据; 后者表示同时只有一个传 输点为用户设备发送数据。 其中, 传输点的类型可以是传统的宏蜂窝基 站, 或者是 RRH, 还可以是 Pico基站等异构结点; 可能是高功率节点也 可能是低功率节点。

图 1是现有技术中的资源分配的一实例示意图,其中 Cdl#l和 Cell#2 进行联合处理, Cell#l为 10个用户设备服务, Cell#2为 2个用户设备服 务。如图 1所示, 当将 Cell#l和 Cell#2中的一半资源(如图 1所示的 ) 同时用于给 Cell#2中的某个用户传输时,将会导致 Cell#l中 10个用户设 备分享剩下的另一半总资源, 从而导致有的小区在有多个用户的情况下 资源受限, 导致系统性能下降。

实施例 1
本发明实施例提供一种多点协作系统中的调度分配方法, 图 2是本 发明实施例的调度分配方法的流程图, 如图 2所示, 所述调度分配方法 包括:
步骤 201,接收多个小区基站或者传输点发送的用于反映各自小区基 站或者传输点的业务负荷量的需求资源参数、 以及用于反映各自小区基 站或者传输点的可用资源状况的可用资源参数;
步骤 202,根据接收到的需求资源参数和可用资源参数,对多个小区 基站或者传输点的优先级进行排序;
步骤 203,根据排序后的优先级,确定多个小区基站或者传输点的调 度模式。
在本实施例中, 反映各自小区基站或者传输点的业务负荷量的需求 资源参数、 以及反映各自小区基站或者传输点的可用资源状况的可用资 源参数可以由各自的小区基站或者传输点获得, 可以通过现有的方法得 到。
在具体实施时, 该需求资源参数具体可以为: 由各自小区基站或传 输点服务的平均每个激活用户设备的需求的物理资源块 (PRB, Physical Resource Block) 数目; 该可用资源参数具体可以为: 由各自小区基站或 传输点服务的平均每个激活用户设备的可用 PRB数目。但值得注意的是, 本发明不限于此, 可以根据实际情况确定具体的参数。
在本实施例中, 小区基站或者传输点的调度模式可以为进行多点或 多小区协作的调度模式、 或者单小区传输的调度模式、 或者单点传输的 调度模式等。
在本实施例中, 步骤 203还可以用于根据优先级, 来确定多个小区 基站或者传输点的资源分配。 以下以集中式和分布式为例, 分别对该调 度分配方法进行详细说明。 在一个实施方式中, 该调度分配方法可以采用集中的方式来实现, 可以应用于多点协作系统的集中式调度器中。 以下以三个 Cell为例进行 说明, 但本发明不限于此。
图 3是本发明实施例的采用集中式调度的实例示意图。如图 3所示, 包括三个 Cell (Cell#1 301、 Cell#2 302和 Cell#3 303 )和一个集中式调度 器 304。 其中, 集中式调度器 304可以是另外的网络设备, 也可以是该多 点协作系统中的其他小区基站或者传输点, 可根据实际情况进行设置。
在具体实施时, Cell#l、 Cell#2和 Cell#3可以将各自服务的每个激活 用户设备的信道状态信息 (CSI, Channel State Information) , 例如包括 RI、 PMI和 CQI等等发送给该集中式调度器 304; 并且, Cell#l、 Cell#2 和 Cdl#3还将各自的需求资源参数和可用资源参数发送给该集中式调度 器 304。
其中, 该需求资源参数用于反映各自小区基站或者传输点的业务负 荷量, 可以用 N_req_k (k=l ...... K) 表示; 该可用资源参数用于反映各 自小区基站或者传输点的可用资源状况, 可以用 N_avai_k (k=l ...... K) 表示。 Κ表示多个小区基站或者传输点的数目。
优选地, N_req_l, N_req_2, ..., N_req_k代表按照各个小区的估计 的信道条件得出的平均每个激活用户的需求的物理资源块(PRB, Physical Resource Block) 数目; N_avai_l , N_avai_2, …, N_avai_k代表每个 小区或者传输点的平均每个激活用户的可用 PRB数目。
由此, 可以新定义两个与小区或传输点相关(cell-specific) 的 X2口 信令,一个是平均每用户需求的 PRB数目,一个是平均每用户可用的 PRB 数目。 并且, 使用这两个新的交互信令可以进行确定多个小区或者传输 点的调度优先级。
在具体实施时, 步骤 202具体可以包括: 优先级计算步骤, 对于每 个小区基站或者传输点, 计算需求资源参数与可用资源参数的比值, 作 为该小区基站或者传输点的优先级基准值; 优先级确定步骤, 根据优先 级基准值, 确定多个小区基站或者传输点的优先级。
例如, N_req_l=3, N_req_2=2, N_req_3=5, N_req_4=10, N_avai_l=7, N_avai_2=2, N_avai_3=6, N_avai_4=3; 则可计算出 Cell#l 对应的优先 级基准值为 3/7, Cell#2对应的优先级基准值为 2/2, Cell#3对应的优先级 基准值为 5/6, Cell#4对应的优先级基准值为 10/3, 则可以确定优先级排 序为: Cell#4, Cell#2、 Cell#3、 Cell#l。
在本实施方式中, 排序的基准值是 (N_req_k/N_avai_k)。 一种特殊情 况是各个小区都负荷很高并且基本一致, 那么基准值可以变为(1/
N_avai_k)。
在另一个实施方式中, 该调度分配方法可以采用分布的方式来实现, 可以应用于多个小区基站或者传输点中的其中一个小区基站或者传输点 中。 以下以两个 Cell为例进行说明, 但本发明不限于此。
图 4是本发明实施例的采用分布式调度的实例示意图。如图 4所示, 包括两个 Cell (Cell#l 401和 Cell#2 402)。 其中, 以 Cell#l 401为例进行 说明, Cell#2 402的情况与此类似, 此处不再赘述。
在具体实施时, Cell#l 401准备以 CoMP模式调度用户设备 UE#1, 需要同时占用 Cell#2 402对应的时频资源; 同时 Cell#2 402准备以 CoMP 模式调度用户设备 UE#2, 需要同时占用 Cdl#l 401对应的时频资源; 则 Cell#l 401将 N_avai_l 和 N_req_l转发到 Cell#2 402, 而 Cell#2 402将 N_avai_2 和 N_req_2转发到 Cell#l 401 ;
在 Cell#l 401接收到 N_avai_2 和 N_req_2之后,也可以获得自身的 N_avai_l 和 N_req_l。可以计算比值 (N_req_k_2/N_avai_k_2)、 以及比值 (N_req_k_l/N_avai_k_l)。 Cell#l 401 的调度器可以对(N_req_k_2/ N_avai_k_2)和 (N_req_k_l/N_avai_k_l)进行比较, 根据比较的结果来决定 两个小区做 CoMP调度和资源占用的优先级。
本发明实施例还提供一种调度分配装置, 应用于多点协作系统中, 与上述调度分配方法相同的内容, 此处不再赘述。
图 5是本发明实施例的调度分配装置的构成示意图, 如图 5所示, 所述调度分配装置包括: 信息接收单元 501、优先级排序单元 502和调度 确定单元 503。
其中, 信息接收单元 501用于接收多个小区基站或者传输点发送的 用于反映各自小区基站或者传输点的业务负荷量的需求资源参数、 以及 用于反映各自小区基站或者传输点的可用资源状况的可用资源参数; 优 先级排序单元 502用于根据接收到的需求资源参数和可用资源参数, 对 多个小区基站或者传输点的优先级进行排序; 调度确定单元 503 用于根 据排序后的优先级, 确定多个小区基站或者传输点的调度模式。
进一步地, 调度确定单元 503还可以用于根据优先级, 来确定多个 小区基站或者传输点的资源分配。
在一个实施方式中, 该调度分配装置可以配置于多点协作系统的集 中式调度器。
在另一个实施方式中, 该调度分配装置可以配置于多个小区基站或 者传输点中的其中一个小区基站或者传输点。
优选地, 该需求资源参数具体可以为: 由小区基站或传输点服务的 平均每个激活用户设备的需求 PRB数目; 该可用资源参数具体可以为: 由小区基站或传输点服务的平均每个激活用户设备的可用 PRB数目。
进一步地, 优先级排序单元 502具体可以包括: 优先级计算单元, 对于每个小区基站或者传输点, 计算需求资源参数与可用资源参数的比 值, 作为该小区基站或者传输点的优先级基准值; 优先级确定单元, 根 据优先级基准值, 确定多个小区基站或者传输点的优先级。
由上述实施例可知, 通过需求资源参数和可用资源参数, 来估计多 点协作系统中不同传输点或者小区之间进行调度的优先级; 从而可以在 考虑到多点协作对单用户带来性能增益的同时, 又避免因为调度次序的 原因而使得个别小区的用户资源受限的情况, 防止了系统性能受损。
实施例 2
本发明实施例还提供一种多点协作系统中的调度分配方法, 应用于 多点协作系统中的小区基站或者传输点。 与实施例 1 相同的内容, 此处 不再赘述。
图 6是本发明实施例中的调度分配方法的流程图, 如图 6所示, 所 述调度分配方法包括:
步骤 601,接收其他小区基站或者传输点发送的用于反映该其他小区 基站或者传输点的业务负荷量的需求资源参数、 以及用于反映该其他小 区基站或者传输点的可用资源状况的可用资源参数;
步骤 602,根据接收到的需求资源参数和可用资源参数、 以及预设的 门限值, 确定该小区基站或者传输点的调度模式。
在具体实施时, 该小区基站或者传输点与该其他小区基站或者传输 点可以以分布式的方式配置。 其中, 其他小区基站或者传输点可以为一 个或多个, 可以根据实际情况确定具体的数目。
在本实施例中, 小区基站或者传输点的调度模式可以为进行多小区 或多点协作的调度模式、 或者单小区传输的调度模式等。 步骤 602 中还 可以根据比较结果确定小区基站或者传输点的资源分配。
在具体实施时, 该需求资源参数具体可以为: 由其他小区基站或传 输点服务的平均每个激活用户设备的需求 PRB数目; 该可用资源参数具 体可以为: 由其他小区基站或传输点服务的平均每个激活用户设备的可 用 PRB数目。
在具体实施时, 步骤 602具体可以包括: 基准值计算步骤, 计算需 求资源参数与可用资源参数的比值, 作为其他小区基站或者传输点的基 准值; 模式确定步骤, 将基准值与所述门限值进行比较, 根据比较结果 确定该小区基站或者传输点的调度模式。
进一步地, 该基准值计算步骤还可以包括: 计算需求资源参数与可 用资源参数的比值的后验值, 作为其他小区基站或者传输点的基准值。 由此, 可以更加准确地进行估计。
以下仍以图 4所示的分布式结构为例, 对该调度分配方法进行详细 描述。其中, Cell#l对应于前述的小区基站或者传输点, Cell#2对应于前 述的其他小区基站或者传输点。
在具体实施时, Cell#l准备以 CoMP模式调度本区用户设备 UE#1, 需要同时占用 Cell#2的时频资源; Cell#2将 N_avai_2 and N_req_2发给 Cell#l; Cell#l可以估计如果以 CoMP模式调度 UE#1, 这段时频资源被 自己占用的话, 那么后验 (N_req_k_2/N_avai_k_2)值会是多少, 由此得到 该比值的后验值。
然后, Cell#l可以将估计出的 (N_req_k_2/N_avai_k_2) 的后验值和 预先定义的门限值进行比较, 来决定 Cdl#l是否以 CoMP模式调度或者 单小区传输模式调度 UE#1。
本发明实施例还提供一种调度分配装置, 所述调度分配装置配置于 多点协作系统中的小区基站或者传输点。 与上述调度分配方法相同的内 容, 此处不再赘述。

其中, 信息接收单元 701用于接收其他小区基站或者传输点发送的 用于反映该其他小区基站或者传输点的业务负荷量的需求资源参数、 以 及用于反映该其他小区基站或者传输点的可用资源状况的可用资源参 数; 调度确定单元 702用于根据接收到的需求资源参数和可用资源参数、 以及预设的门限值, 确定该小区基站或者传输点的调度模式。
优选地, 该需求资源参数具体可以为: 由其他小区基站或传输点服 务的平均每个激活用户设备的需求 PRB数目; 该可用资源参数具体可以 为: 由其他小区基站或传输点服务的平均每个激活用户设备的可用 PRB 数目。
进一步地, 调度确定单元 702具体可以包括: 基准值计算单元, 计 算需求资源参数与可用资源参数的比值, 作为其他小区基站或者传输点 的基准值; 模式确定单元, 将基准值与门限值进行比较, 根据比较结果 确定该小区基站或者传输点的调度模式。
