Description

一种资源分配方法及装置
本申请要求于2021年04月14日提交国家知识产权局、申请号为202110400297.0、申请名称为“一种资源分配方法及装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请实施例涉及通信技术领域，尤其涉及一种资源分配方法及装置。
背景技术
一方面，随着科技发展流媒体技术已经被人们广泛使用。在流媒体技术中，通常将流媒体数据(例如视频数据)分为多个数据单元，然后将多个数据单元依次传输至终端，以便终端播放该流媒体数据。例如，数据单元可以是视频数据中的视频帧，也可以是将视频帧分割成多个视频块(tile)中的一个视频tile。然后将视频帧或者视频tile依次发送至终端。
通常，可以用向终端传输的流媒体数据中传输正确(或错误)的数据单元的占比，来反映该终端对应的用户是否被满足。此外，针对包含多个用户的用户群体，可以用被满足用户在用户群体中的占比，反映用户群体整体上的用户满意率。例如，针对一个服务有多个用户的小区，可以用被满足用户在这多个用户中的占比，反映该小区的用户满足率。
另一方面，在无线通信技术中，可以采用不同调度方案，为终端分配时频资源。例如，可以将时频资源分配给其中一个终端，即通过该时频资源向一个终端传输数据；再例如，可以利用空分复用技术等技术，将时频资源分配给多个终端，以使通过该时频资源向多个终端传输数据。
因此，当向多个终端传输流媒体数据时，如何设计通信系统的调度方案，从而提高系统的用户满足率，这是目前需要解决的问题。

另一种示例中，第一设备101可以为移动通信网络中的中继站，本申请的通信系统可如图3所示。该通信系统中包括：多个UE、中继站、接入网络设备、核心网(CN)以及应用服务器。其中，关于接入网设备、核心网以及应用服务器的功能、结构的描述，可参照上文图2对应的内容。中继站可以为接入和回传一体化(integrated access and backhaul，IAB)基站或者终端设备。此外，中继站可以按照本申请实施例所提供方法，将流媒体数据传输至多个UE。

相关技术中，在第一设备向多个第二设备传输数据的情况下，针对一个时频资源例如一个资源块组(resource block group，RBG)，可以有多种调度方案：例如可以将该RBG分配给一个第二设备，用于传输该第二设备对应的数据；再例如还可以将该RBG分配给多个第二设备，例如第一设备可以利用空分复用技术在该RBG上通过波束赋形技术向多个第二设备传输数据。
其中，当将RBG分配给多个第二设备(例如第一设备采用空分复用技术在RBG上向多个第二设备传输数据)时，由于用户信道之间的相关性，就造成了传输速率下降。例如，当将该RBG分配给第二设备a时，第二设备a的传输速率为R1 ins；当将该RBG分配给第二设备b时，第二设备b的传输速率为R2 ins；当将该RBG分配给第二设备a和第二设备b时，第二设备a和第二设备b的传输速率则分别为α1·R1 ins和α2·R2 ins。其中，α1·R1 ins＜R1 ins，α2·R2 ins＜R2 ins。α1和α2分别为考虑第二设备a和第二设备b的信道之间的相关性造成瞬时速率下降的系数，其中α1＜1；α2＜1。
为了选择合适的资源调度方案，一种技术方案中采用了基于比例公平(proportional fairness，PF)的用户调度策略来为第二设备分配资源。该技术方案中：
首先，计算第二设备的调度优先级PF，其中第二设备的调度优先级PF满足以下公式一：
Figure PCTCN2022076073-appb-000001
其中，R ins为根据第二设备当前的信道状态参数(例如：信道状态信息(channel state information，CSI)、秩指示(rank indication，RI))计算出的第二设备在待分配时频资源上的当前速率；R his为第二设备在前一段时间内所接收数据的历史速率。
其中，针对信道质量较好或者在前一段时间内占据较多资源的第二设备，其历史平均速率将会逐渐增大，使得调度优先级逐渐变小，以使得之后系统会优先为其他优先级较高的设备分配资源。反之，针对信道质量较差或者在前一段时间内占据较少资源的第二设备，其历史平均速率将会逐渐减少，使得调度优先级逐渐增大，以使得之后系统为该第二设备分配资源的机会就越大。
然后，对于各资源调度方案，计算第二设备的调度优先级之和，然后选择调度优先级之和最大的资源调度方案执行。
示例性的，以两个第二设备(如，第二设备a和第二设备b)在一个RBG上的资源调度方案为例，包括三种资源调度方案：将该RBG分配给第二设备a、将该RBG分配给第二设备b，以及将该RBG分配给第二设备a和第二设备b(即第二设备a和第二设备b复用该RBG)。
针对将该RBG分配给第二设备a的资源调度方案：调度优先级之和为
Figure PCTCN2022076073-appb-000002
针对将该RBG分配给第二设备b的资源调度方案：调度优先级之和为
Figure PCTCN2022076073-appb-000003
针对第二设备a和第二设备b复用该RBG的资源调度方案：调度优先级之和为
Figure PCTCN2022076073-appb-000004
确定
Figure PCTCN2022076073-appb-000005
中的最大值，进而确定资源调度方案。
上述技术方案主要是以最大化PF为目标，来选择资源调度方案。然而在将上述技术方案应用于流媒体数据传输时，由于流媒体业务对传输有时延要求，因此若不考虑流媒体业务的时延要求，则会影响用户体验，降低系统的用户满足率。下面以向两个第二设备(如，第二设备a和第二设备b)调度资源为例，进行说明：
假设两个第二设备所传输的视频均为60帧/秒(即每16.67ms一个视频帧)，且两个第二设备所传输业务的帧时延预算(frame delay budget，FDB)均为10ms，可以理解为视频帧需要在10ms内完成传输，且数据帧为10Kbits。另外，系统的时隙长度为0.5ms。图5所示为第一设备向两个第二设备传输数据的时刻。其中，第二设备b的视频帧在8ms时的剩余数据量为2Kbits，剩余传输时间为2ms；另外对于第二设备a在8ms时开始传输新一数据帧，因此第二设备a的视频帧在8ms时的剩余数据量为10Kbits，剩余传输时间为10ms。另外，第二设备a占用后续时频资源的速率为1.8Mbps，第二设备b占用后续时频资源的速率为1Mbps。若第二设备a与第二设备b共同占据后续时频资源(例如利用空分复用技术，使两个设备复用后续时频资源)则第二设备a的速率为1.2Mbps，第二设备b的速率为0.8Mbps。
在假设第二设备a和第二设备b的历史速率接近相同的情况下，则通过计算可知：第二设备a与第二设备b复用时频资源的调度优先级之和最大。进而在后续的时频资源上，采用第二设备a与第二设备b复用时频资源的调度方案。进而可以计算出第二设备b在10ms时刻 之前仅能传输1.6Kbits(即0.8Mbps*2ms＝1.6Kbits)。即在第二设备b的剩余传输时间内，无法将第二设备b的视频帧的剩余数据完成传输，进而造成帧传输错误。
针对上述技术问题，本申请实施例提供一种资源分配方法。该方法可以应用于资源分配装置。如图6所示，为本申请实施例提供的一种资源分配装置的结构示意图。在具体实施时，本申请实施例所提供的资源分配装置可以由图6所示资源分配装置20来实现。其中，资源分配装置可以为图1中的第一设备，也可以是独立于第一设备且能够与第一设备进行数据交互的硬件设备。
其中，资源分配装置20包括：至少一个处理器201以及存储器202。另外，资源分配装置20还可以包括通信线路203以及通信接口204。
其中，处理器201用于执行存储器202中的计算机执行指令，以实现本申请所提供的资源分配方法。
具体的，处理器201可以是一个通用中央处理器(central processing unit，CPU)，微处理器，特定应用集成电路(application-specific integrated circuit，ASIC)，或一个或多个用于控制本申请方案程序执行的集成电路。
存储器202可以是只读存储器(read-only memory，ROM)或可存储静态信息和指令的其他类型的静态存储设备，随机存取存储器(random access memory，RAM)或者可存储信息和指令的其他类型的动态存储设备，也可以是电可擦可编程只读存储器(electrically erasable programmable read-only memory，EEPROM)、只读光盘(compact disc read-only memory，CD-ROM)或其他光盘存储、光碟存储(包括压缩光碟、激光碟、光碟、数字通用光碟、蓝光光碟等)、磁盘存储介质或者其他磁存储设备、或者能够用于携带或存储具有指令或数据结构形式的程序代码并能够由计算机存取的任何其他介质，但不限于此。存储器可以是独立存在，通过通信线路203与处理器相连接。存储器也可以和处理器集成在一起。
通信线路203可以包括数据总线，用于在上述组件之间传送信息。
通信接口204，用于与其他装置进行通信。例如，当资源分配装置独立于第一设备时，资源分配装置20可以通过通信接口204与第一设备通信。
可以理解，本申请中描述的资源分配装置20可以是网络设备，也可以是网络设备的部件(例如网络设备的处理器或芯片)，也可以是能实现全部或部分网络设备功能的逻辑模块或软件，还可以是前述逻辑模块或软件与前述部件的结合。
具体的，以下以图1所示通信系统为例对本申请实施例所提供方法进行介绍。其中，第一设备可以是网络设备，也可以是网络设备的部件(例如网络设备的处理器或芯片)，也可以是能实现全部或部分网络设备功能的逻辑模块或软件，还可以是前述逻辑模块或软件与前述部件的结合。第二设备可以是终端，也可以是终端的部件(例如终端的处理器或芯片)，也可以是能实现全部或部分终端功能的逻辑模块或软件，还可以是前述逻辑模块或软件与前述部件的结合。如图7所示该方法可以包括：
S301、资源分配装置确定第一调度方案对应的第一优先级。
具体的，在网络设备向M个终端传输数据时，可以采用以下调度方案中的一种调度方案：网络设备通过时频资源向M个终端中的一个终端传输数据，以及网络设备通过M个终端中多个终端复用时频资源的方式向多个终端传输数据。其中，时频资源具体可以为一个或多个资源元素(resource element，RE)、一个或多个资源块(resource block，RB)或者一个或多个RBG等。此时第一调度方案可以为上述调度方案中的一种。
示例性的，以M为3(即三个终端：终端a、终端b以及终端c)以及在一个RBG上的资源调度方案为例，第一调度方案可以为以下任一种调度方案：
方案一、终端a占据该RBG，网络设备在该RBG向终端a传输数据；
方案二、终端b占据该RBG，网络设备在该RBG向终端b传输数据；
方案三、终端c占据该RBG，网络设备在该RBG向终端c传输数据；
方案四、终端a和终端b共同占据该RBG，网络设备通过空分复用在该RBG向终端a和终端b传输数据；
方案五、终端b和终端c共同占据该RBG，网络设备通过空分复用在该RBG向终端b和终端c传输数据；
方案六、终端a和终端c共同占据该RBG，网络设备通过空分复用在该RBG向终端a和终端c传输数据；
方案七、终端a、终端b和终端c共同占据该RBG，网络设备通过空分复用在该RBG向终端a、终端b和终端c传输数据。
另外，本申请实施例中，第一调度方案对应的第一优先级与M个终端分别对应的第一数据量和第一可用时长相关。
其中，第一数据量为在第一调度方案下M个终端分别对应的剩余数据量。第一可用时长为在时延约束和第一调度方案下，M个终端分别对应的剩余可用传输时长。
例如，在图5的示例中，若第一调度方案为在8ms-10ms时间段内使第二设备a和第二设备b复用时频资源。那么，在第一调度方案下，第二设备a对应的剩余数据量为7.6Kbits(即10Kbits-1.2Mbps*2ms＝7.6Kbits)，即第二设备a对应的第一数据量为7.6Kbits；第二设备b对应的剩余数据量为0.4Kbits(即2Kbits-0.8Mbps*2ms＝0.4Kbits)，即第二设备b对应的第一数据量为0.4Kbits。另外，由于帧时延预算为10ms，因此在时延约束和第一调度方案下，第二设备a对应的剩余可用传输时长为8ms，即第二设备a对应的第一可用时长为8ms；在时延约束和第一调度方案下，第二设备b对应的剩余可用传输时长为0，即第二设备a对应的第一可用时长为0。
即在上述示例中，一方面，第一数据量可以理解为在按照第一调度方案分配时频资源下，M个终端分别对应的数据单元的剩余数据量。其中，数据单元可以为数据帧，或者数据帧内单独作为一个传输单元的部分数据(例如，视频条(slice)、视频块(tile))。也就是说，终端i对应的第一数据量可以表示为：Q i,r-Q i,c，其中Q i,r表示该终端i当前传输的数据单元的剩余数据量，Q i,c表示在第一调度方案下在所调度的时频资源上该终端i的数据单元的传输数据量。
另一方面，第一可用时长可以理解为在按照第一调度方案分配时频资源之后，在时延约束下，M个终端分别对应的数据单元的剩余可用传输时长。也就是说，终端i对应的第一可用时长可以表示为：T i,r-T s，其中T i,r表示由时延约束确定的该终端i所传输数据单元的当前剩余可用时长，T s表示所调度的时频资源对应的时长。
需要说明的是，在具体实施过程中，上述M个终端分别对应的第一数据量可以是相同的，也可以是不同的。例如在图5的示例中，第二设备a和第二设备b的第一数据量是不同的；再例如，当在第一调度方案下，第二设备a和第二设备b的剩余数据量相同时，则第二设备a和第二设备b的第一数据量可以是相同的。以此类推，上述M个终端分别对应的第一可用时长可以是相同的，也可以是不同的。
另外，在不同应用场景下，本申请实施例中的时延约束可以根据实际需要进行配置。例如，可以根据所传输的业务来配置时延约束，不同业务对应的时延约束可以不同，也可以相同。具体的，时延约束可以通过FDB体现，其中不同业务对应相应的FDB。示例性的，上述图5示例中，根据第二设备a和第二设备b所传输业务，确定出两个第二设备的FDB均为10ms，因此这种情况下两个第二设备对应相同的时延约束。当第二设备a和第二设备b所传输视频的FDB不同时，则两个第二设备对应的时延约束也可以是不同的。也就是说，本申请实施例中M个终端分别对应的时延约束可以是相同的，也可以是不同的，对此本申请可以不做限制。
也就是说，资源分配装置可以根据M个终端分别对应的第一数据量和第一可用时长确定第一调度方案对应的第一优先级。
也就是说，本申请实施例所提供方法中，针对一种调度方案(即第一调度方案)：首先，利用M个终端分别对应的第一数据量和第一可用时长，确定第一调度方案的优先级(即第一优先级)。例如，在第一调度方案下，M个终端分别对应的第一数据量越多、第一可用时长越短，就说明在M个终端分别对应的第一可用时长内将M个终端分别对应的剩余数据量传输完的可能性越小。进而，若无法在第一可用时长内将剩余数据量传输完，则会导致数据播放异常，进而影响用户使用体验。因此可以将第一调度方案的优先级设为一个较低的优先级。反之，在第一调度方案下，M个终端分别对应的第一数据量越少、第一可用时长越长，就说明在M个终端分别对应的第一可用时长内将M个终端分别对应的剩余数据量传输完的可能性越大，因此产生数据播放异常的可能性就相对较低，因此这种情况下可以为第一调度方案的优先级设为一个较高的优先级，以优先按照第一调度方案分配资源。
换句话讲，在具体实施过程中，一方面，第一调度方案的优先级，可以与M个终端分别对应的第一数据量成正相关关系。以M个终端中一个终端i为例，第一调度方案的优先级随着该终端i对应的第一数据量Q i,r-Q i,c的增大而提高、随着该终端i对应的第一数据量Q i,r-Q i,c的减小而降低。另一方面，第一调度方案的优先级，可以与M个终端分别对应的第一可用时长成负相关关系。以M个终端中一个终端i为例，第一调度方案的优先级随着该终端i对应的第一数据量T i,r-T s的增大而降低、随着该终端i对应的第一数据量T i,r-T s的减小而提高。
S302、资源分配装置根据第一优先级，为M个终端中的至少一个终端分配时频资源。
例如，当第一优先级高于其他调度方案的优先级时，或者第一优先级高于预设的优先级阈值时，按照第一调度方案分配时频资源。再例如，当第一优先级低于其他调度方案的优先级，或者第一优先级低于预设的优先级阈值时，确定不按照第一调度方案为M个终端中的至少一个终端分配时频资源，进而可以按照其他调度方案分配时频资源。
本申请实施例所提供的方法基于流媒体数据的两个特点(第一、流媒体数据可以分为多个数据单元进行独立传输或播放；第二、流媒体数据具有对应的时延约束)，进而利用M个终端分别对应的第一数据量(即在第一调度方案下终端对应的剩余数据量)和第一可用时长(即在时延约束和第一调度方案下，终端对应的剩余可用传输时长)确定第一调度方案的优先级来确定分配时频资源的方式，从而提高被满足用户的占比，即提高用户满足率。例如，通过该方法，可以选择出在M个终端分别对应的第一可用时长内将M个终端分别对应的剩余数据量传输完的可能性最大的调度方案，进而尽可能保证数据单元能够在时延约束条件下完成传输，从而提高被满足用户的占比，提高用户满足率。
在一种实现方式中，上述方法中S301可以具体包括S301a1-S301a2：
S301a1、资源分配装置根据M个终端分别对应的第一数据量和第一可用时长，确定M 个终端分别对应的第一需求参数。
其中，第一需求参数与在第一可用时长的约束下第一数据量的传输速率相关。
在一种示例中，第一需求参数可以为在第一可用时长的约束下第一数据量的传输速率。例如第一需求参数R i满足：
Figure PCTCN2022076073-appb-000006
其中，Q i,r、Q i,c、T i,r、T s的定义可参照上文。在此不再赘述。需要说明的是，下文中若无特别解释，相同符号的参数的定义相同，为了简洁描述下文中不再另行说明。
在另一种示例中，第一需求参数也可以是能够反映上述传输速率的其他参数。例如，第一需求参数R i可以满足：
Figure PCTCN2022076073-appb-000007
其中，δ为用于保证分母为正值的常数。其中，在具体实施时，当T s和T i,r的粒度(或理解成精度)相同(例如T s和T i,r的粒度都为10ms)，或者T i,r的粒度是T s的粒度的整数倍(例如T s的粒度为1ms，T i,r的粒度为10ms)时，此时T i,r-T s的最小值为0，此时δ的取值范围例如可以为δ＞0，即δ为任一正值均可以保证分母为正值，例如在实施时δ可以取e -10，其中e为自然常数。当T s和T i,r的粒度不同时，此时δ的取值范围例如可以为δ＞T s-min(T i,r)。
S301a2、资源分配装置根据第一需求参数，确定第一优先级。
在一种示例中，可以根据所有M个终端分别对应的第一需求参数，确定第一优先级。
例如，可以根据所有M个终端分别对应的第一需求参数之和，确定第一优先级。M个终端分别对应的第一需求参数R i之和R sum可以满足：
Figure PCTCN2022076073-appb-000008
其中，R sum越大，第一优先级越低；R sum越小，第一优先级越高。
再例如，可以根据所有M个终端分别对应的第一需求参数的倒数之和，确定第一优先级。M个终端分别对应的第一需求参数的倒数
Figure PCTCN2022076073-appb-000009
之和R sum可以满足：
Figure PCTCN2022076073-appb-000010
其中，R sum越大，第一优先级越高；R sum越小，第一优先级越低。
再例如，还可以根据所有M个终端分别对应的第一需求参数的乘积
Figure PCTCN2022076073-appb-000011
或者根据所有M个终端分别对应的第一需求参数的倒数的乘积
Figure PCTCN2022076073-appb-000012
确定第一优先级。再例如，还可以根据所有M个终端分别对应的第一需求参数的指数函数(例如
Figure PCTCN2022076073-appb-000013
)，或者根据所有M个终端分别对应的第一需求参数的倒数的指数函数(例如
Figure PCTCN2022076073-appb-000014
)，确定第一优先级。再例如，还可以根据M个终端分别对应的第一需求参数的对数函数(例如
Figure PCTCN2022076073-appb-000015
)，或者根据M个终端分别对应的第一需求参数的倒数的对数函数(例如
Figure PCTCN2022076073-appb-000016
)，确定第一优先级。再例如，还可以根据所有M个终端分别对应的第一需求参数的加权求和之后的值，确定第一优先级。其中，各终端分别对应的第一需求参数的权值，可以根据不同终端对应的服务质量(quality of service，QoS)等级、或不同终端所对应业务的QoS等级等信息来确定。
也就是说，在具体实施过程中，可以采用关于M个终端分别对应的第一需求参数的函数关系，确定第一优先级。对于采用哪种具体的函数关系确定第一优先级，本申请实施例可以不做限制。另外，在实际实施时，上述关于M个终端分别对应的第一需求参数的函数关系， 可以体现为如上述示例中的函数表达式，也可以由表格等形式体现。当以表格形式体现函数关系时，则可以通过查表的方式获得第一需求参数。
在另一种示例中，可以根据M个终端中部分终端分别对应的第一需求参数，确定第一优先级。
例如，在计算出M个终端分别对应的第一需求参数后，从这M个第一需求参数中选择数值最大的K个第一需求参数。然后根据这K个第一需求参数，确定第一优先级。
与上文根据所有M个终端分别对应的第一需求参数确定第一优先级同理，根据M个终端中部分终端分别对应的第一需求参数确定第一优先级的方式也可以有多种。例如，根据K个第一需求参数之和，确定第一优先级；根据K个第一需求参数的乘积，确定第一优先级；根据K个第一需求参数的加权求和之后的值，确定第一优先级；根据K个第一需求参数的指数函数，确定第一优先级，等等。
上述实现方式中，通过确定M个终端分别对应的与在第一可用时长约束下第一数据量的传输速率相关的第一需求参数，并根据第一需求参数确定调度方案的优先级。从而可以确定出结合流媒体数据特点的调度方案优先级，进而根据该优先级分配时频资源，能够提高用户满足率。
例如，在图5的示例中，在8ms时刻时，系统的传输情况为：第二设备a：剩余数据量Q a,r＝10Kbits，剩余可用时长T a,r＝10ms；第二设备b：剩余数据量Q b,r＝2Kbits，剩余可用时长T b,r＝2ms；另外，被分配的时频资源单位为RBG，系统时隙为0.5ms。另外，第二设备a占据RBG的速率为1.8Mbps；第二设备b占用RBG的速率为1Mbps；第二设备a和第二设备b复用RBG时，第二设备a的速率为1.2Mbps，第二设备b的速率为0.8Mbps。则：
1、针对第二设备a占用RBG的调度方案一：
第二设备a在一个RBG内传输的数据量Q a,c为：Q a,c＝1.8Mbps×0.5ms＝0.9Kbits。
以根据第二设备分别对应的第一需求参数之和来确定第一优先级为例，则本示例中两个第二设备的第一需求参数之和R sum，可以满足：
Figure PCTCN2022076073-appb-000017
进而可以得出调度方案一对应的R sum为2.291Mbps。
2、针对第二设备b占用RBG的调度方案二：
第二设备b在一个RBG内传输的数据量Q b,c为：Q b,c＝1Mbps×0.5ms＝0.5Kbits。
两个第二设备的第一需求参数之和R sum，可以满足：
Figure PCTCN2022076073-appb-000018
进而可以得出调度方案二对应的R sum为2.053Mbps。
3、针对第二设备a和第二设备b复用RBG的调度方案三：
第二设备a在一个RBG内传输的数据量Q a,c为：Q a,c＝1.2Mbps×0.5ms＝0.6Kbits；
第二设备b在一个RBG内传输的数据量Q b,c为：Q b,c＝0.8Mbps×0.5ms＝0.4Kbits。
两个第二设备的第一需求参数之和R sum，可以满足：
Figure PCTCN2022076073-appb-000019
进而可以得出调度方案二对应的R sum为2.056Mbps。
由于上述调度方案二的R sum最小，即调度方案二的优先级最高，所以选择让第二设备b占用RBG进行传输。类似的，在后续系统时间8.5ms时刻、9ms时刻、9.5ms时刻出计算相应的各种调度方案的R sum，可以发现依然是第二设备b占用RBG的调度方案优先级最高。即第二设备b在8ms-10ms之内的传输数据量为1Mbps×2ms＝2Kbits。因此，第二设备b可以在时延约束下完成数据单元的传输。
在另一种实现方式中，第一优先级还与M个终端分别对应的数据单元正确率或数据单元错误率相关。
其中，一个终端对应的数据单元正确率，表示已向该终端传输的流媒体数据中，传输正确的数据单元的占比。一个终端对应的数据单元错误率，表示向该终端传输的流媒体数据中，传输错误的数据单元的占比。通常情况下，可以用数据单元正确率或者数据单元错误率，反映用户是否被满足。例如，当流媒体数据为视频数据，数据单元为视频帧时，数据单元正确率可以指帧正确率，当帧正确率小于99％时则说明无法满足用户的使用体验。另外，针对包含多个用户的用户群体，可以用被满足用户在用户群体中的占比，反映用户群体整体上的用户满意率。例如，针对一个服务多个用户的小区，可以用被满足用户在这多个用户中的占比，反映该小区的用户满足率。
在本方法具体实施时，一种方式中，终端可以将指示数据单元正确率或数据单元错误率的信息上报给网络设备，进而可以从终端向网络设备上报的信息中确定数据单元正确率或错误率。另一种方式中，在网络设备能够确定数据单元包括的数据包的情况下，可以根据数据包的接收情况，确定终端对应的数据单元正确率或数据单元错误率，进而获取这些信息以获取终端对应的数据单元正确率或数据单元错误率。例如，在网络设备向终端发送流媒体数据的过程中，首先通过确定数据包是否被正确传输，可以确定数据包对应的数据单元是否被正确传输；然后，通过统计一段时间内被正确传输的数据单元的占比，从而得到终端对应的数据单元正确率。本申请中，对于获取终端对应的数据单元正确率或数据单元错误率的具体方式可以不做限制。
在该实现方式中，通过根据M个终端分别对应的第一数据量、第一可用时长以及数据单元正确率或数据单元错误率，确定第一调度方案的第一优先级。这样确定出的第一优先级能够进一步体现流媒体数据在传输中的特性，以达到更高的用户满足率。
以帧正确率为例，通常情况下，一方面，当M个终端中的目标终端对应的帧正确率高于一定阈值(即第一阈值)时，再将帧正确率提高也很难使用户获得更好的使用体验。因此，在目标终端对应的帧正确率高于第一阈值的情况下，为了保持目标终端的用户使用体验，目标终端对应的帧正确率越低，则给目标终端分配传输资源的需求就越大；反之目标终端对应的帧正确率越高，则给目标终端分配传输资源的需求就越小。以目标终端对应第一阈值为99％为例，在目标终端帧正确率大于99％时，目标终端对应的帧正确率例如为99.9％时对应的传输资源分配需求小于目标终端对应的帧正确率例如为99.1％时对应的传输资源分配需求。
另一方面，当M个终端中的目标终端对应的帧正确率低于第一阈值时，则目标终端对应的帧正确率越低，则说明将帧正确率提高至第一阈值的难度越大；反之目标终端对应的帧正确率越高，则说明将帧正确率提高至第一阈值的难度越小。因此，在目标终端对应的帧正确率低于第一阈值的情况下，目标终端对应的帧正确率越低，则给目标终端分配传输资源的需求就越小；反之目标终端对应的帧正确率越高，则给目标终端分配传输资源的需求就越大。以目标终端对应第一阈值为99％为例，在目标终端帧正确率小于99％时，目标终端对应的帧 正确率例如为80％时对应的传输资源分配需求大于目标终端对应的帧正确率例如为50％时对应的传输资源分配需求。
进而，一方面，在一种可能的设计中，针对M个终端中的终端：
当数据单元正确率小于第一阈值时，第一优先级与数据单元正确率正相关。当数据单元正确率大于第一阈值时，第一优先级与数据单元正确率负相关。
其中，第一阈值可以根据用户被满足情况确定，例如上文中在帧正确率达到99％时说明满足用户使用体验，则当数据单元正确率为帧正确率时可以将第一阈值设为99％。
另一方面，由于数据单元正确率与数据单元错误率存在对应关系，因此与上述设计同理，在另一种可能的设计中，针对M个终端中的终端：
当数据单元错误率小于第二阈值时，第一优先级与数据单元错误率正相关。当数据单元错误率大于第二阈值时，第一优先级与数据单元正确率负相关。
其中，第二阈值可以根据用户被满足情况确定，例如上文中在帧正确率达到99％时说明满足用户使用体验，则第一阈值为99％，进而第二阈值为1％。
具体的，由于数据单元错误率与数据单元正确率存在对应关系，因此数据单元错误率与第一优先级的关系的示例，可以参照上文数据单元正确率与第一优先级的关系的示例，此处不再赘述。
在第一优先级与M个终端分别对应的第一数据量、第一可用时长以及数据单元正确率相关的情况下，下面示例性的介绍一种确定第一优先级的方式，具体包括：
S1、根据M个终端分别对应的第一数据量、第一可用时长以及数据单元正确率，确定M个终端分别对应的第一需求参数。
其中，M个终端中终端i对应的第一需求参数R i'满足以下公式二：
Figure PCTCN2022076073-appb-000020
其中，M(FRR i)可以理解为关于终端i的数据单元正确率FRR i的惩罚函数，M(FRR i)的变化趋势例如图8所示。其中，当数据单元正确率小于第一阈值时，M(FRR i)随着数据单元正确率的增大而增大，当数据单元正确率大于第一阈值时，M(FRR i)随着数据单元正确率的增大而减小。
示例性的，函数M(FRR i)可以满足：
Figure PCTCN2022076073-appb-000021
S2、根据第一需求参数，确定第一优先级。
其中，根据第一需求参数确定第一优先级的实现过程，可参照上述S301a2的内容。
上述实现方式中，通过将调度方案的优先级与M个终端分别对应的第一数据量、第一可用时长以及数据单元正确率或数据单元错误率相关，进而可以提高用户满足率。
例如，为便于方案理解，此处假设终端1和终端2的信道条件、当前数据单元的剩余数据量、以及当前数据单元的剩余可用时长、时延约束条件都相同。另外，终端1的数据单元正确率FRR 1＝80％，第一阈值为99％，终端2的数据单元正确率FRR 2＝50％，第一阈值为50％。终端1和终端2分别对应的惩罚函数的取值满足：M 1(FRR 1)＝10M 2(FRR 2)。则：
1、针对终端1占用时频资源的调度方案一：
以根据第二设备分别对应的第一需求参数之和来确定第一优先级为例，终端1和终端2 的第一需求参数之和R sum，可以满足：
Figure PCTCN2022076073-appb-000022
2、针对终端2占用时频资源的调度方案一：
终端1和终端2的第一需求参数之和R sum，可以满足：
Figure PCTCN2022076073-appb-000023
由终端1和终端2的信道条件、当前数据单元的剩余数据量、以及当前数据单元的剩余可用时长、时延约束条件都相同，可知：
Figure PCTCN2022076073-appb-000024
并且
Figure PCTCN2022076073-appb-000025
又因为M 1(FRR 1)＝10M 2(FRR 2)，所以调度方案一的R sum比调度方案二的R sum小。因此，调度方案一的优先级更高，从而可以提高终端1的数据单元正确率，提高终端1的用户使用体验。
在又一种实现方式中，在流媒体数据传输过程中，可以采用分层编码的传输方式，即将流媒体数据分为基本层(base layer，BL)数据和增强层(enhancement layer，EL)数据。其中，BL数据可以使解码器解码出基本流媒体内容，保障用户的基本体验，BL数据通常数据量较小。EL数据则包括更多细节信息，用于提升视频质量，其数据量通常较大。针对分层编码视频，在网络传输过程中，也是将两种码流分开传输，并提供不同的QoS保障。例如BL的数据包和EL的数据包会配置不同的5G QoS指示符(5G QoS identifier，5QI)。然后，在网络设备进行资源调度时会根据QoS要求，保证BL数据包的调度优先级会高于EL数据包的调度优先级。在分层传输方案下，用户是否被满足取决于其BL层数据单元正确率(例如BL帧正确率)是否大于预设阈值(例如99.99％)，且EL数据单元正确率(例如EL帧正确率)是否大于预设阈值(例如50％)。
需要说明的是，上述描述中，将流媒体数据分层后的数据分为基本层数据和增强层数据，在具体应用过程中在对流媒体数据进行分层编码时，不同分层也可以采用其他名称。例如，基本层数据也可以被称为基础层数据等其他名称，增强层数据也可以被称为加强层数据等其他名称。分层编码的实质是将流媒体数据分为满足用户基本体验和提升音视频质量的两层数据，对于两层数据的名称可以有不同的命名方式。本申请实施例所提供方法对于两层数据的名称不做限制。
基于上述考虑，本实现方式中，M个终端分别对应的第一数据量，包括第一基本层数据量和第一增强层数据量。
其中，第一基本层数据量，为在第一调度方案下M个终端分别对应的基本层剩余数据量。第一增强层数据量，为在第一调度方案下M个终端分别对应的增强层剩余数据量。
例如，若终端a的当前剩余数据量为2Kbits，其中包括基本层剩余数据量0.5Kbits，增强层剩余数据量1.5Kbits。另外，在第一调度方案下，被分配的时频资源上，能够传输终端a的0.3Kbits的基本层数据以及1Kbits的增强层数据。那么，终端a对应的第一基本层数据量则为0.2Kbits，第一增强层数据量则为0.5Kbits。
另外，M个终端分别对应的第一可用时长包括第一基本层可用时长和第一增强层可用时长。
其中，第一基本层可用时长，为在时延约束和第一调度方案下M个终端分别对应的基本层的剩余可用传输时长。
例如，若终端a的时延约束包括：基本层的帧时延预算为10ms，增强层的帧时延预算为12ms；在时延约束下，终端a的当前基本层的剩余可用传输时长为8ms，增强层的剩余可用传输时长为9ms；第一调度方案所分配时频资源的时长为0.5ms，则终端a对应的第一基本层可用时长为7.5ms，第一增强层可用时长为8.5ms。
需要说明的是，上述示例中对于终端a的基本层和增强层分别对应不同的时延约束(10ms和12ms)，在一些场景中终端的基本层和增强层的时延约束也可以相同，对此本申请可以不做限制。
也就是说，上述实现方式中，第一调度方案的优先级是与M个终端分别对应的第一基本层数据量、第一增强层数据量、第一基本层可用时长和第一增强层可用时长这四种信息相关的。在确定第一调度方案的优先级时，可基于M个终端分别对应的上述四种信息来确定。这样一来，可以根据基本层和增强层的不同情况，设置调度方案的优先级，以选择更优的调度方案进行资源分配。
基于上述实现方式，下面对确定第一调度方案的第一优先级的两种实现过程进行描述：
实现过程一：
上述S301可以具体包括：
S301b1、根据M个终端分别对应的第一基本层数据量、第一增强层数据量、第一基本层可用时长和第一增强层可用时长，确定M个终端分别对应的第一需求参数。
其中，一个终端的第一需求参数与第一基本需求参数、第一增强需求参数相关。其中，第一基本需求参数用于反映在第一基本层可用时长的约束下第一基本层数据量的传输速率，第一增强需求参数用于反映在第一增强层可用时长的约束下第一增强层数据量的传输速率。
示例性的，终端i的第一基本需求参数R i BL可以满足：
Figure PCTCN2022076073-appb-000026
其中，Q i,r BL表示终端i当前的基本层剩余数据量，Q i,c BL表示在第一调度方案下在所调度的时频资源上该终端i的基本层传输数据量，Q i,r BL-Q i,c BL即为终端i对应的第一基本层数据量；T i,r BL表示终端i当前的基本层剩余可用传输时长，T s表示第一调度方案所调度时频资源的时长，T i,r BL-T s即为终端i对应的第一基本层可用时长。
终端i的第一增强需求参数R i EL可以满足：
Figure PCTCN2022076073-appb-000027
其中，Q i,r EL表示终端i当前的增强层剩余数据量，Q i,c EL表示在第一调度方案下在所调度的时频资源上该终端i的增强层传输数据量，Q i,r EL-Q i,c EL即为终端i对应的第一增强层数据量；T i,r EL表示终端i当前的增强层剩余可用传输时长，T s表示第一调度方案所调度时频资源的时长，T i,r EL-T s即为终端i对应的第一基本层可用时长。
示例性的，可以通过对终端i的第一基本需求参数和第一增强传输参数进行加权求和等处理，确定终端i对应的第一需求参数。
例如，考虑到相比于增强层数据的传输，基本层数据的传输的重要性更高。因此，终端i对应的第一需求参数R i、第一基本需求参数R i BL以及第一增强需求参数R i EL可以满足以下公式：
R i＝R i BL+R i EL
Figure PCTCN2022076073-appb-000028
Figure PCTCN2022076073-appb-000029
其中，X、Y、δ'、δ”可根据应用需要设置。X、Y用于保障R i BL的取值变化对R i的影响，大于的R i EL取值变化对R i的影响。例如，在具体实施时，可以通过使X＞1并且y＞0，从而保障R i BL的取值变化对R i的影响，大于的R i EL取值变化对R i的影响。δ'、δ”为用于保证分母不为0并且使R i BL和R i EL为正值的常数。与上文对δ的取值范围同理，在具体实施时，一方面，当T s和T i,r BL的粒度相同，或者T i,r BL的粒度是T s的粒度的整数倍时，此时δ'的取值范围例如可以为δ'＞0。当T s和T i,r BL的粒度不同时，此时δ'的取值范围例如可以为δ'＞T s-min(T i,r BL)。另一方面，当T s和T i,r EL的粒度相同，或者T i,r EL的粒度是T s的粒度的整数倍时，此时δ”的取值范围例如可以为δ”＞0。当T s和T i,r EL的粒度不同时，此时δ”的取值范围例如可以为δ”＞T s-min(T i,r EL)。
S301b2、根据第一需求参数，确定第一优先级。
具体的，S301b2的实现过程可参照上文S301a2的描述，在此不再赘述。
实现过程二：
在确定第一调度方案的第一优先级的过程中，第一优先级还可以与M个终端分别对应的基本层数据单元正确率和增强层数据单元正确率相关，或者与M个终端分别对应的基本层数据单元错误率和增强层数据单元错误率相关。因此，上述S301可以具体包括：
S301c1、根据M个终端分别对应的第一基本层数据量、第一增强层数据量、第一基本层可用时长、第一增强层可用时长、基本层数据单元正确率和增强层数据单元正确率，确定M个终端分别对应的第一需求参数。或者，根据M个终端分别对应的第一基本层数据量、第一增强层数据量、第一基本层可用时长、第一增强层可用时长、基本层数据单元错误率和增强层数据单元错误率，确定M个终端分别对应的第一需求参数。
其中，一个终端的第一需求参数与第一基本需求参数、第一增强需求参数、基本层数据单元正确率和增强层数据单元正确率相关，或者一个终端的第一需求参数与第一基本需求参数、第一增强需求参数、基本层数据单元错误率和增强层数据单元错误率相关。其中，第一基本需求参数用于反映在第一基本层可用时长的约束下第一基本层数据量的传输速率，第一增强需求参数用于反映为在第一增强层可用时长的约束下第一增强层数据量的传输速率。
示例性的，下面以终端对应的第一需求参数与第一基本需求参数、第一增强需求参数、基本层数据单元正确率和增强层数据单元正确率相关为例，对终端对应的第一需求参数的确定过程进行介绍：
与S301b1同理，终端i的第一基本需求参数R i BL可以满足：
Figure PCTCN2022076073-appb-000030
其中，Q i,r BL、Q i,c BL、T i,r BL、T s的含义，可参照上文S301b1中的描述，此处不再赘述。
终端i的第一增强传输参数R i EL可以满足：
Figure PCTCN2022076073-appb-000031
其中，Q i,r EL、Q i,c EL、T i,r EL的含义，可参照上文S301b1中的描述，此处不再赘述。
另外，若终端i的基本层数据单元正确率为FRR i BL，终端i的增强层数据单元正确率为FRR i EL。终端i对应的第一需求参数R i、第一基本需求参数R i BL以及第一增强需求参数R i EL可以满足以下公式：
R i＝R i BL+R i EL
Figure PCTCN2022076073-appb-000032
Figure PCTCN2022076073-appb-000033
其中，关于X、Y、δ'、δ”的定义和取值方式可以参照S301b1相关内容。
M 1(FRR i BL)和M 2(FRR i EL)分别为FRR i BL和FRR i EL的惩罚函数。示例性的，M 1(FRR i BL)和M 2(FRR i EL)可以分别满足：
Figure PCTCN2022076073-appb-000034
Figure PCTCN2022076073-appb-000035
S301c2、根据第一需求参数，确定第一优先级。
具体的，S301c2的实现过程可参照上文S301a2的描述，在此不再赘述。
上述实施例中，主要是以第一调度方案为例，对本申请实施例所提供资源分配方法进行介绍。当需要从多种调度方案中选择合适的调度方案进行资源分配时，可以按照上述对第一调度方案类似的处理方式，分别确定出多种调度方案分别对应的优先级。然后根据多种调度方法分别对应的优先级，选择合适的调度方案，并向终端分配时频资源。
进而，如图9所示，在执行S302之前，该方法还可以包括：
S303、资源分配装置确定第二调度方案对应的第二优先级。
其中，第二优先级与M个终端分别对应的第二数据量和第二可用时长相关。第二数据量，为在第二调度方案下M个终端分别对应的剩余数据量。
第二可用时长，为在时延约束和第二调度方案下M个终端分别对应的剩余可用传输时长。
其中，第二调度方案可以包括一种调度方案，也可以包括多种调度方案。当第二调度方案包括多种调度方案时，第二调度方案对应的第二优先级包括多种调度方案分别对应的优先级。另外，可以理解的，当第二调度方案包括多种调度方案时，上述第二数据量和第二可用时长，也应当理解为多种调度方案中各调度方案分别对应的第二数据量和第二可用时长。
其中，确定第二调度方案对应的第二优先级的实施过程，可以参照上述S301确定第一调度方案的第一优先级的实施过程，在此不再赘述。
进一步的，在一种实现方式中，S302则具体包括：
S3021、资源分配装置根据第一优先级和第二优先级，为M个终端中的至少一个终端分配时频资源。
例如，可以根据第一优先级和第二优先级，从第一调度方案和第二调度方案中选择优先级最高或较高的调度方案，并按照该调度方案为M个终端中的至少一个终端分配时频资源。
在一种实现方式中，上述S303可以具体包括：
S303a1、根据M个终端分别对应的第二数据量和第二可用时长，确定M个终端分别对应的第二需求参数。
其中，第二需求参数，与在第二可用时长的约束下第二数据量的传输速率相关。
S303a2、根据第二需求参数，确定第二优先级。
具体的，S303a1-S303a2的实施过程可以参照上文S301a1-S301a2。
其中，与第一优先级类似的，第二优先级还可以与M个终端分别对应的数据单元正确率或数据单元错误率相关。
进而，与第一优先级类似，第二优先级与M个终端分别对应的数据单元正确率或数据单元错误率相关，可以包括：
当数据单元正确率小于第一阈值或数据单元错误率小于第二阈值时，第二优先级与数据单元正确率或数据单元错误率正相关；当数据单元正确率大于第一阈值或数据单元错误率大于第二阈值时，第二优先级与数据单元正确率或数据单元错误率负相关。
在一种实现方式中，在采用分层编码的传输方式的情况下，上述方法中：
第二数据量包括第二基本层数据量和第二增强层数据量。
其中，第二基本层数据量，为在第二调度方案下M个终端分别对应的基本层剩余数据量；第二增强层数据量，为在第二调度方案下M个终端分别对应的增强层剩余数据量。
第二可用时长包括第二基本层可用时长和第二增强层可用时长。
其中，第二基本层可用时长，为在时延约束和第二调度方案下M个终端分别对应的基本层的剩余可用传输时长；第二增强层可用时长，为在时延约束和第二调度方案下M个终端分别对应的增强层的剩余可用传输时长。
也就是说，上述实现方式中，在确定第二调度方案的第二优先级时，第二调度方案的优先级是与M个终端分别对应的第二基本层数据量、第二增强层数据量、第二基本层可用时长和第二增强层可用时长，这四种信息相关的。即在确定第二调度方案的优先级时，可用基于M个终端分别对应的上述四种信息，来确定。这样一来，可以根据基本层和增强层的不同情况，设置第二调度方案的优先级，以选择更优的调度方案进行资源分配。
可以理解的是，上述资源分配装置为例实现对应的功能，其包括了执行各功能对应的硬件结构和/或软件模块。本申请实施例根据上述方法示例对资源分配方法进行功能模块的划分。例如，可以对应各个功能划分各个功能模块，也可以将两个或两个以上的功能集成在一个出来模块中。上述集成的模块既可以采用硬件的形式实现，也可以采用软件功能模块的形式实现。可选的，本申请实施例中对模块的划分是示意性的，仅仅为一种逻辑功能划分，实际实施时可以由另外的划分方式。
如图10所示，为本申请实施例提供的一种资源分配装置的组成示意图。该资源分配装置40可以是芯片或片上系统。该资源分配装置40也可以是第一设备101。该资源分配装置40还可以是能够实现第一设备101全部或部分功能的软件功能，或者是在平台(例如云平台)上实例化的虚拟化功能。该资源分配装置40可以用于执行上述实施例中所提供的资源分配方法。作为一种实现方式，该资源分配装置40可以包括：
确定单元401，用于确定第一调度方案对应的第一优先级。
其中，第一优先级与M个终端分别对应的第一数据量和第一可用时长相关；第一数据量，为在第一调度方案下，M个终端分别对应的剩余数据量；第一可用时长，为在时延约束和第一调度方案下，M个终端分别对应的剩余可用传输时长；M＞1。
资源分配单元402，用于根据第一优先级，为M个终端中的至少一个终端分配时频资源。
