一种数据调度方法和设备
技术领域
本发明涉及通信技术领域， 特別涉及一种数据调度方法和设备。 背景技术
由于无线蜂窝通信系统中频谱利用率的限制，每个用户所占带宽有限， 因 此越来越难以满足高速数据业务的传输要求。在未来无线宽带移动网络中为用 户提供更为可靠的高速数据服务， 将会成为迫切的需求。
为了提高频谱利用率， 在 LTE-A ( Long Term Evolution Advanced, 先进的 长期演进） 中引入了 CA ( Carrier Aggregation, 载波聚合）技术。 CA技术是 将分散在多个频段的频谱资源利用起来， 获取更大的带宽，从而提高峰值数据 速率和系统调度速率， 同时也解决了运营商频谱不连续的问题。
多载波终端（使用 CA技术的终端， 即激活多载波的终端 )要接收的数据 在每个载波的空口分別独立接收， 多载波终端接收数据的方案为： 多载波终端 在收到各载波的空口发来的数据后，将接收的数据进行拼装得到最终完整的数 据并传递到多载波终端的上层供使用。 因此， 如何在多个载波中传输数据， 实 现频谱资源的利用率最大化的同时如何获得最佳的调度速率和公平性成为了 要解决的技术关键点。

可选地， 所述处理器， 用于确定所述第一载波单元为所述第一终端的主载 波单元或辅载波单元之后； 若为辅载波单元，且所述第一载波单元是所述第二 终端的主载波单元， 或者所述第二终端为非多载波终端； 则在为第二终端分配 所述第一载波的物理资源后， 为所述第一终端分配所述第一载波的物理资源； 若为主载波单元，且所述第一载波单元是第二终端的辅载波单元，在为所述第 一终端分配第一载波单元的物理资源之后，为所述第二终端分配所述第一载波 的物理资源包括： 具体用于若所述第一载波单元为所述第一终端的主载波单 元， 则将所述第一终端加入到第一队列中， 若所述第一载波单元为所述第一终 端的辅载波单元， 则将所述第一终端加入第二队列中； 若所述第一载波单为所 述第二终端的主载波单元或者第二终端为非多载波终端，则将第二终端加入第 一队列中， 若所述第一载波单元为所述第二终端的辅载波单元， 则将所述第二 终端加入第二队列中；先按照第一队列中各终端的调度优先级从高到低依次分 配所述第一载波单元的物理资源，然后按照第二队列中各终端的调度优先级从 高到低依次分配所述第一载波单元的物理资源。
可选地， 所述处理器， 还用于接收第一终端发送的信道质量信息之后， 获 取所述第一载波单元当前的资源利用率；若所述第一载波单元当前的资源利用 率大于第一阈值， 则去激活所述第一多载波终端在所述载波单元的调度。
可选地， 所述处理器，还用于在去激活所述第一多载波终端在所述载波单 元的调度之后， 获取所述第一终端的緩存状态； 若所述第一载波单元当前的资 源利用率小于第二阈值， 所述第二阈值小于所述第一阈值， 并且所述第一终端 的緩存状态为积压， 则激活所述多载波终端在所述载波单元的调度。
从以上技术方案可以看出， 具有以下优点： 以上方案中， 多载波终端在每 个载波单元上所获得的物理资源和这个载波单元上的非多载波终端获得的物 理资源是相同的， 由于多载波终端可以使用多个载波单元， 因此多载波终端所 能得到的总物理资源数就可以得到稳定的增加，体现出相比非多载波终端明显 的优势。 实现了终端间的差异化。 另外， 多载波终端在每个载波单元上的调度 优先级独立计算， 因此在每个载波单元上和非多载波终端平等竟争物理资源， 即以单个载波单元为单位来看，多载波终端和非多载波终端之间仍然能够获得 比较好的公平性。 附图说明
为了更清楚地说明本发明实施例中的技术方案，下面将对实施例描述中所 需要使用的附图作筒要介绍， 显而易见地， 下面描述中的附图仅仅是本发明的 一些实施例，对于本领域的普通技术人员来讲，在不付出创造性劳动性的前提 下， 还可以根据这些附图获得其他的附图。

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。
因此， 多载波终端在每个载波上调度时， 调度优先级的计算过程中， 使用 的平均调度速率是用户 /承载级的速率， 也即是该多载波终端在每个载波上的 平均调度速率之和。 该多载波终端的调度优先级的计算公式如下： Vx iorityca (式 1 )
Figure imgf000010_0001
其中， Pr''。n yca是指该多载波终端在 cCi上的调度优先级， 。'是指该多 载波终端在 CCi上当前的瞬时调度速率， 。·是指该多载波终端在 cCi上的平 均调度速率， N是多载波终端调度的载波单元个数。
对于以上方案， 存在如下缺陷：
1、 多载波终端相比非多载波终端没有性能上的优势。 通过调度优先级的 计算公式可以看到， 分母为多载波终端的所有 CC上的平均调度速率之和， 如 果多载波终端在各 CC上的信道质量相同或接近，这时多载波终端和非多载波 终端的调度速率是相同的， 多载波终端相比非多载波终端并没有获得优势。 因 此多载波终端业务无法获得稳定的高速率， 终端间的差异化也无法体现。
2、 调度公平性会比较差。 通过调度优先级的计算公式可以看到， 分母为 多载波终端的所有 CC上的平均调度速率之和， 如果多载波终端在各 CC上的 信道质量相同或接近， 这时多载波终端和非多载波终端的调度速率是相同的， 调度优先级可收敛到相同的值， 可获得比较好的公平性。 但是， 如果多载波终 端在各 CC上的信道质量差异较大，则多载波终端的调度优先级的收敛值将会 不可预期， 公平性也就会恶化。 另外， 由于各个 CC存在带宽不同、 接入的用 户数不同等情况， 也都会对公平性造成影响。
本发明实施例提供了一种数据调度方法， 如图 1所示， 包括：
101: 接收多载波终端发送的信道质量信息；
由于终端的信道质量信息会实时的变化， 因此在数据调度方案中， 该步骤
101可以周期性的执行， 后续步骤也可以随之循环执行。
102: 使用上述信道质量信息计算上述多载波终端在载波单元上当前的瞬 时调度速率； 获取上述多载波终端在上述载波单元的平均调度速率；
本步骤中的平均调度速率是指多载波终端在上述载波单元上获得的平均 调度速率， 比如， 一种计算方法是上述多载波终端使用上述载波单元传输的数 据总量与上述多载波终端占用上述载波单元的物理资源的时间的商。
103: 使用上述瞬时调度速率与平均调度速率计算上述多载波终端在上述 载波单元上的调度优先级； 对于多载波终端以及非 载波终端而言，均可以采用上述 101~103的方法 获得与其对应的调度优先级 如下给出了一个示例， 假定， 调度优先级数值越 大优先级越高， 请参阅表 1:
表 1
Figure imgf000011_0001
104: 若需要为两个或两个以上的终端分配上述载波单元的物理资源， 则 按照各终端的调度优先级从高到低依次分配上述载波单元的物理资源。
上述物理资源可以是空口资源，数据信道资源等， 具体的资源种类本发明 实施例不予限定。本实施例方法的执行者可以是在多载波技术中执行载波单元 的物理资源分配的设备， 例如 LTE中的 eNB ( evolved Node B, 演进型基站）， WCDMA ( Wideband Code Division Multiple Access , 宽带码分多址）中的 RNC ( Radio Network Controller, 无线网络控制器）， 可以理解的是在多载波技术中 执行载波单元的物理资源分配的设备种类繁多， 无法穷举， 以上举例不应理解 为对本发明实施例的限定。
作为一个举例， 请参阅表 1 , 在步骤 104中可以确定需要为 5个终端分配 某一载波单元的物理资源， 上表 1的调度优先级并没有排序。 实际上， 调度优 先级可以进行排序， 也可以不排序， 均不影响本实施例的实现。
物理资源的分配方案具体可以为： 首选选出调度优先级最高的 13, 也即 是终端标识为 NCA223这一终端，首先为这个终端分配物理资源，然后如果上 述载波单元的物理资源有剩余， 则为优先级第二高的 11 , 也即是终端标识为 CA123 的这一终端分配物理资源， 同理依次为调度优先级为第三、 第四、 第 五的终端分配物理资源， 可以理解的是由于物理资源有限，排后面的终端是有 可能分配不到资源的。 另外可以理解的是，如果仅需要为一个终端分配上述载 波单元的物理资源， 那么可以直接分配， 可以不用考虑其调度优先级的问题。 以上方案中，多载波终端在每个载波单元上所获得的物理资源和这个载波 单元上的非多载波终端平等的竟争物理资源，由于多载波终端可以使用多个载 波单元， 因此多载波终端所能得到的总物理资源数就可以得到稳定的增加，体 现出相比非多载波终端明显的优势。 总体而言， 本发明实施例的技术方案实现 了终端间的差异化。
另外， 多载波终端在每个载波单元上的调度优先级独立计算， 因此在每个 载波单元上和非多载波终端平等竟争物理资源， 即以单个载波单元为单位来 看， 多载波终端和非多载波终端之间仍然能够获得比较好的公平性。
进一步地， 本发明实施例还给出了获取平均调度速率的可选方案， 如下： 在按照各终端的调度优先级从高到低依次分配上述载波单元的物理资源后，计 算上述多载波终端在上述载波单元的平均调度速率，并存储计算得到的平均调 度速率。 可以理解的是， 如果存储有平均调度速率， 上述方法在循环执行过程 中，执行到步骤 102时， 可以直接读取到上述多载波终端在上述载波单元上的 平均调度速率。
以整个无线通信系统而言， 采用前述方案多载波终端相比于非多载波终 端，将有倍数级的物理资源优势， 多载波终端可能会占用过多的物理资源导致 非多载波终端的物理资源被挤占，本发明实施例还提供了在保证多载波终端物 理资源优势的前提下， 兼顾非多载波终端的物理资源的方案， 具体如下： 上述 方法还包括：
确定上述载波单元为上述多载波终端的主载波单元或辅载波单元；并对上 述两个或两个以上的终端按照调度优先级从高到低排序；上述对上述两个或两 个以上的终端按照调度优先级从高到低排序包括：
若上述载波单元为上述多载波终端的主载波单元，则将上述多载波终端的 调度优先级加入到第一队列中，上述第一队列中包含任意个数的非多载波终端 的调度优先级或者其他多载波终端的调度优先级；对上述第一队列中的调度优 先级进行排序；
若上述载波单元为上述多载波终端的辅载波单元，则将上述多载波终端的 调度优先级加入到第二队列中，上述第二队列中包含任意个数的多载波终端的 调度优先级； 对上述第二队列中的调度优先级进行排序； 那么， 上述步骤 103中，按照各终端的调度优先级从高到低依次分配上述 载波单元的物理资源包括：
先按照第一队列中各终端的调度优先级从高到低依次分配上述载波单元 的物理资源，然后按照第二队列中各终端的调度优先级从高到低依次分配上述 载波单元的物理资源。
相比于图 1对应的实施例，本实施例引入了上述载波单元是多载波终端的 何种载波类型的判断，对于多载波终端以及非多载波终端而言，仍然可以采用 上述 101~103的方法获得与其对应的调度优先级； 如下给出了一个示例， 由于 非多载波终端只有对应一个载波所以载波类型可以是空， 请参阅表 2:
表 2
Figure imgf000013_0001
由本实施例的前述说明， 上述表 将会存在两个排序， 分別请参阅表 3 和表 4, 其中表 3和表 4是采用的是降序排列， 采用升序排列也不影响本发明 实施例的实现。 其中表 3对应上述第一队列， 表 4对应第二队列；
表 3
Figure imgf000013_0002
表 4 终端标识 终端类型 载波类型 调度优先级
CA126 多载波终端 辅载波单元 16
CA124 多载波终端 辅载波单元 11
基于以上表 3和表 4, 本实施例方案会先为表 3内的终端分配物理资源， 分配的方案参考表 1相应的分配方案， 这里不再赘述； 表 3内的终端全部分配 到物理资源后， 为表 4内的终端分配物理资源， 分配的方案参考表 1相应的分 配方案， 这里不再赘述。
采用本实施例方案， 就单个载波单元而言， CA终端是否有机会获得物理 资源， 需要上述载波单元的 Non-CA ( Non Carrier Aggregation, 非载波聚合 ) 终端和 CA PCC ( Primary Component Carrier, 主载波单元 )终端（即上述载波 单元是多载波终端的主载波单元 )获得物理资源以后，在还有剩余物理资源剩 余的情况下， CA SCC终端（即上述载波单元是多载波终端的辅载波单元）才 会够获得物理资源， 否则， 不能得到物理资源。 该方案， 多载波终端可以在其 主载波单元上与 Non-多载波终端平等竟争物理资源， 在其辅载波单元上需要 等到 Non-多载波终端和 CA SCC ( Secondary Component Carrier, 辅载波单元 ) 终端获得物理资源以后， 才有机会获得物理资源。 这样， 多载波终端仍然可以 获得比 Non-多载波终端更多的物理资源， 但是又不过多挤占 Non-多载波终端 的物理资源， 在体现用户差异化的前提下， 还可以兼顾公平性。
另夕卜， 采用式 1指导数据调度的方案还可能存在如下问题： 无线通信系统 整体的调度速率并不总是稳定的会有提升。这是由于多载波终端使用的多个载 波单元， 多个载波单元分为 PCC ( Primary Component Carrier, 主载波单元） 和 SCC ( Secondary Component Carrier,辅载波单元 ),其中主载波单元为 1个， 辅载波单元则可以有 1个以上； 以上例中的式 1为例， 4 定 CC1作为主载波 单元， CC2~CCi作为辅载波单元， 当辅载波上的空闲数据信道资源很少甚至 于没有的时候， 如果多载波终端还在辅载波上抢占其它非多载波终端的资源， 那么就可能会出现终端在无法获得物理资源的情况下还要消耗控制信道资源， 造成无线通信系统整体性能下降。
为了解决该技术问题， 本发明实施例还提供了如下技术方案： 上述接收多 载波终端发送的信道质量信息之后还包括：获取上述载波单元当前的资源利用 率； 若上述载波单元当前的资源利用率大于第一阈值， 则去激活上述多载波终 端在上述载波单元的调度。上述第一阈值用于确定载波单元当前是否不太可能 有物理资源分配给 CA SCC终端， 这个阈值设置的较高， 则 CA SCC终端有更 多机会获得物理资源， 设置得低些， 则可以更好的满足 CA PCC终端和 Non- 多载波终端的物理资源需求， 第一阈值具体设置为多少本发明实施例不予限 定。该方案可以消除多载波终端在整网资源利用率 4艮高的情况下带来的性能损 失， 从而提高整个无线通信系统的整体性能。
进一步地，本发明实施例还提供如何激活多载波终端在载波单元的调度的 方案。 上述方法还包括： 获取上述多载波终端的緩存状态； 若上述载波单元当 前的资源利用率小于第二阈值， 上述第二阈值小于上述第一阈值， 并且上述终 端的緩存状态为积压， 则激活上述多载波终端在上述载波单元的调度； 否则保 持上述多载波终端在上述载波单元的调度状态不变。上述第二阈值用于确定在 何种情况下可以为 CA SCC终端分配物理资源， 设置的高， 则有利于 CA SCC 终端获得物理资源， 设置得低些， 则可以更好的满足 CA PCC终端和 Non-多 载波终端的物理资源需求， 第二阈值具体设置为多少本发明实施例不予限定。
本实施例方案， 可以在载波单元资源有富余， 多载波单元又有较多的数据 传输需求的情况下，再次激活多载波单元在其辅载波单元的调度，使多载波终 端能够在载波单元的物理资源允许的情况下获得更多的物理资源。
基于前述实施例的， 本发明实施例还给出了一个更为具体的举例说明， 本 实施例以基站分配载波单元的数据信道资源为例，请参阅图 2,包括如下步骤： 201: 终端向基站上报信道质量信息；
202: 基站通过接收到的信道质量获得当前载波单元的频谱效率， 进而获 取上述终端当前载波单元上的瞬时调度速率； 假定： 瞬时调度速率为 Rca , 上 述当前载波单元为 CCi。
203: 基站获取上述终端在当前载波单元上的平均调度速率； 假定平均调 度速率为 rra ;
204: 基站计算上述终端在当前载波单元上的调度优先级；
具体的计算可以参考如下： Pr iorityCCi = ^。
rca
对多个终端执行步骤 201~204以后，会获得多个终端要求分配上述载波单 元的数据信道资源， 上述多个终端中可能包含有多载波终端， 也可能包含有 Non-多载波终端； 而且还会获得各终端的调度优先级， 示例可以参考表 1。
以上步骤 201~204 适用于多载波终端也适用于非多载波终端的调度优先 级计算。
205: 基站按照调度优先级从高到低的顺序， 为终端分配当前载波单元的 数据信道资源。 然后进入步骤 201 ;
本步骤中的具体的分配过程， 可以参考为表 1中各终端分配资源的过程。 206: 基站计算分配了数据信道资源的终端在上述当前载波单元上传输的 数据量，并使用该数据量以及之前使用该载波单元传输的历史数据量的总和除 以上述终端占用上述数据信道资源的时间，得到上述分配了数据信道资源的终 端在上述当前载波单元上的平均调度速率； 进入 203。
以上方案中，多载波终端在每个载波单元上所获得的物理资源和这个载波 单元上的非多载波终端获得的物理资源是相同的，由于多载波终端可以使用多 个载波单元， 因此多载波终端所能得到的总物理资源数就可以得到稳定的增 加， 体现出相比非多载波终端明显的优势。 实现了终端间的差异化。
另外， 多载波终端在每个载波单元上的调度优先级独立计算， 因此在每个 载波单元上和非多载波终端平等竟争物理资源， 即以单个载波单元为单位来 看， 多载波终端和非多载波终端之间仍然能够获得比较好的公平性。
以整个无线通信系统而言，采用前述图 2对应的方案多载波终端相比于非 多载波终端，将有倍数级的物理资源优势， 多载波终端可能会占用过多的物理 资源导致非多载波终端的物理资源被挤占，本发明实施例还提供了在保证多载 波终端物理资源优势的前提下，兼顾多载波终端的物理资源的方案，具体如下： 上述方法还可以包括：
确定当前载波单元是否是上述终端的主载波单元或辅载波单元；并对上述 两个或两个以上的终端按照调度优先级从高到低排序； 请参阅图 2B , 在步骤 204和 205之间可以加入如下步骤：
207: 将多载波终端中的 CA PCC终端和 Non-多载波终端分为一组， 将 CA SCC分为另一组， 在以上两个组分別按照调度优先级排序； 具体的示例可 以参阅表 2~表4； 那么在步骤 205中， 按照调度优先级从高到低的顺序， 先为 第一组中的终端分配当前载波单元的数据信道资源；然后按照调度优先级从高 到低的顺序， 为第二组中的终端分配当前载波单元的数据信道资源； 具体分配 过程可以参阅表 3和表 4中终端的物理资源分配。其他步骤与前述实施例相同， 不再一一赘述
采用本实施例方案， 就单个载波单元而言， CA终端是否有机会获得物理 资源， 需要上述载波单元的 Non-CA ( Non Carrier Aggregation, 非载波聚合 ) 终端和 CA PCC终端（即上述载波单元是多载波终端的主载波单元 )获得物理 资源以后， 在还有剩余物理资源剩余的情况下， CA SCC终端（即上述载波单 元是多载波终端的辅载波单元）才会够获得物理资源， 否则， 不能得到物理资 源。 该方案， 多载波终端可以在其主载波单元上与 Non-多载波终端平等竟争 物理资源， 在其辅载波单元上需要等到 Non-多载波终端和 CA PCC终端获得 物理资源以后， 才有机会获得物理资源。 这样， 多载波终端仍然可以获得比 Non-多载波终端更多的物理资源， 但是又不过多挤占 Non-多载波终端的物理 资源， 在体现用户差异化的前提下， 还可以兼顾公平性。
另外， 由于采用式 1指导数据调度的方案还可能存在如下问题： 无线通信 系统整体的调度速率并不总是稳定的会有提升。这是由于多载波终端使用的多 个载波单元， 多个载波单元分为 PCC ( Primary Component Carrier, 主载波单 元）和 SCC ( Secondary Component Carrier, 辅载波单元）， 其中主载波单元为 1个， 辅载波单元则可以有 1个以上； 以上例中的式 1为例， 4 定 CC1作为主 载波单元， CC2~CCi作为辅载波单元， 当辅载波上的空闲数据信道资源^艮少 甚至于没有的时候，如果多载波终端还在辅载波上抢占其它非多载波终端的资 源，那么就可能会出现终端在无法获得物理资源的情况下还要消耗控制信道资 源， 造成无线通信系统整体性能下降。 为了解决该技术问题， 本发明实施例还 提供了如下技术方案， 该方案可以在前述图 2对应方案的执行过程中同步执 行， 请参阅图 3 , 包括：
301 : 获取当前载波单元当前的资源利用率； 获取多载波终端的緩存状态； 302: 判断当前载波单元当前的资源利用率是否大于第一阈值， 如果是， 进入 303; 否则， 进入 304;
上述第一阈值用于确定载波单元当前是否不太可能有物理资源分配给多 载波终端， 这个阈值设置的较高则 CA SCC终端有更多机会获得物理资源，设 置得低些则可以更好的满足 C A PCC终端和 Non-多载波终端的物理资源需求， 该阈值具体设置为多少本发明实施例不予限定。
303: 去激活上述多载波终端在上述当前载波单元的调度； 进入 301 ; 本步骤可以消除多载波终端在整网资源利用率很高的情况下带来的性能 损失， 从而提高整个无线通信系统的整体性能。
304: 判断当前载波单元当前的资源利用率是否小于第二阈值， 如果是， 进入 305;
上述第二阈值用于确定在何种情况下可以为 CA SCC终端分配物理资源， 设置的高则有利于 CA SCC终端获得物理资源，设置得低些则可以更好的满足 CA PCC终端和 Non-多载波终端的物理资源需求，第二阈值具体设置为多少本 发明实施例不予限定。
305: 判断上述终端的緩存状态是否积压， 如果是， 进入 306;
306: 激活上述多载波终端在上述当前载波单元的调度；
本步骤可以在载波单元资源有富余，多载波单元又有较多的数据传输需求 的情况下，再次激活多载波单元在其辅载波单元的调度，使多载波终端能够在 载波单元的物理资源允许的情况下获得更多的物理资源。
本发明实施例还给出了一种数据调度设备，该设备可以是在多载波技术中 执行载波单元的物理资源分配的任意设备， 例如 LTE中的 eNB, WCDMA中 的 RNC等， 可以理解的是在多载波技术中执行载波单元的物理资源分配的设 备种类繁多， 无法穷举， 以上举例不应理解为对本发明实施例的限定。 如图 4 所示， 包括：

以上方案中，多载波终端在每个载波单元上所获得的物理资源和这个载波 单元上的非多载波终端获得的物理资源是相同的，由于多载波终端可以使用多 个载波单元， 因此多载波终端所能得到的总物理资源数就可以得到稳定的增 加， 体现出相比非多载波终端明显的优势。 实现了终端间的差异化。
另外， 多载波终端在每个载波单元上的调度优先级独立计算， 因此在每个 载波单元上和非多载波终端平等竟争物理资源， 即以单个载波单元为单位来 看， 多载波终端和非多载波终端之间仍然能够获得比较好的公平性。
进一步地， 如图 5所示， 上述计算单元 403 , 还用于在将所述第一载波单 元的物理资源分配给第一终端以后，计算第一终端在第一载波单元的平均调度 速率；

以上方案中，多载波终端在每个载波单元上所获得的物理资源和这个载波 单元上的非多载波终端获得的物理资源是相同的，由于多载波终端可以使用多 个载波单元， 因此多载波终端所能得到的总物理资源数就可以得到稳定的增 加， 体现出相比非多载波终端明显的优势。 实现了终端间的差异化。

进一步地， 所述处理器 903 , 用于确定所述第一载波单元为所述第一终端 的主载波单元或辅载波单元之后； 若为辅载波单元，且所述第一载波单元是所 述第二终端的主载波单元， 或者所述第二终端为非多载波终端； 则在为第二终 端分配所述第一载波的物理资源后，为所述第一终端分配所述第一载波的物理 资源； 若为主载波单元， 且所述第一载波单元是第二终端的辅载波单元， 在为 所述第一终端分配第一载波单元的物理资源之后，为所述第二终端分配所述第 一载波的物理资源包括：具体用于若所述第一载波单元为所述第一终端的主载 波单元， 则将所述第一终端加入到第一队列中， 若所述第一载波单元为所述第 一终端的辅载波单元， 则将所述第一终端加入第二队列中； 若所述第一载波单 为所述第二终端的主载波单元或者第二终端为非多载波终端，则将第二终端加 入第一队列中， 若所述第一载波单元为所述第二终端的辅载波单元， 则将所述 第二终端加入第二队列中；先按照第一队列中各终端的调度优先级从高到低依 次分配所述第一载波单元的物理资源，然后按照第二队列中各终端的调度优先 级从高到低依次分配所述第一载波单元的物理资源。

另外， 多载波终端在每个载波单元上的调度优先级独立计算， 因此在每个 载波单元上和非多载波终端平等竟争物理资源， 即以单个载波单元为单位来 看， 多载波终端和非多载波终端之间仍然能够获得比较好的公平性。
进一步地， 上述基带处理单元 1003 , 还用于在按照各终端的调度优先级 从高到低依次分配所述载波单元的物理资源后，计算所述多载波终端在所述载 波单元的平均调度速率， 并存储计算得到的平均调度速率。

第一终端在每个载波单元上所获得的物理资源和这个载波单元上的非多 载波终端获得的物理资源是相同的， 由于第一终端可以使用多个载波单元， 因 此第一终端所能得到的总物理资源数就可以得到稳定的增加，体现出相比非第 一终端明显的优势。 实现了终端间的差异化。 另外， 第一终端在每个载波单元 上的调度优先级独立计算，因此在每个载波单元上和非第一终端平等竟争物理 资源， 即以单个载波单元为单位来看， 第一终端和非多载波终端之间仍然能够 获得比较好的公平性。
