Description

调度模式的确定方法及装置
本申请要求于2021年8月31日提交中国国家知识产权局、申请号为202111013716.1、发明名称为“调度模式的确定方法及装置”的专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及无线通信领域，尤其涉及调度模式的确定方法及装置。
背景技术
多输入多输出(multiple input multiple output，MIMO)技术可以指发射端使用多个发射天线发送信号，接收端使用多个接收天线接收信号。如此，可以通过多个天线实现多发多收。通过MIMO技术可以实现在不增加频谱资源和天线发射功率的情况下，成倍的提高系统信道容量和频谱效率，还可以增强网络覆盖。因此，MIMO技术已经成为无线通信的核心技术。
在MIMO技术中，为了获得较宽的工作带宽，提出了将多个阵面拼接。例如，如图1所示，为有源天线单元(active antenna unit，AAU)的模块逻辑示意图。图1所示的AAU包括数字中频(digital intermediate frequency，DIF)，与DIF连接的片上射频(radio on chip，RoC)0和RoC 1，与RoC 0连接的阵面0，以及与RoC 1连接的阵面1。其中，阵面0有4个收发机(tranceiver，TRX)，分别为TRX 0、TRX 1、TRX 2和TRX 3，阵面1有4TRX，分别为TRX 4、TRX 5、TRX 6和TRX 7，阵面0对应的频点和阵面1对应的频点不同，阵面0和阵面1的带宽为400MHz，也就是说，图1所示的AAU是将两个带宽为400MHz的4发射通道4接收通道(4T4R)的阵面拼接在了一起。相比于阵面0或阵面1的带宽，拼接后的AAU的带宽为800MHz，增大了一倍。但是，拼接后的AAU包括多个阵面，如何通过多个阵面发射波束一直是研究的热点。
发明内容
本申请实施例提供调度模式的确定方法及装置，可以合理调度多个频点(或阵面)的发射通道，提升系统容量。
为达到上述目的，本申请的实施例采用如下技术方案：
第一方面，提供了一种调度模式的确定方法，执行该调度模式的确定方法的通信装置可以为基带单元(baseband unit，BBU)；也可以为应用于BBU中的模块，例如芯片或芯片系统。下面以执行主体为BBU为例进行描述。该方法包括：获取第一调度模式对应的第一参数，该第一参数为采用该第一调度模式发射多个第一波束的情况下，通过该多个第一波束发送的数据包的传输参数；获取第二调度模式对应的第二参数，该第二参数为采用该第二调度模式发射多个第二波束的情况下，通过该多个第二波束发送的数据包的传输参数；获取第三调度模式对应的第三参数，该第三参数为采用该第三调度模式发射第三波束的情况下，通过该第三波束发送的数据包的传输参 数；根据该第一参数、该第二参数和该第三参数，确定发射波束的调度模式。
基于上述第一方面提供的方法，可以确定第一调度模式对应的第一参数，第二调度模式对应的第二参数，第三调度模式对应的第三参数，并根据第一参数、第二参数和第三参数确定发射波束的调度模式，使得第一调度模式、第二调度模式和第三调度模式中，吞吐率性能较好的调度模式可以作为发射波束的调度模式，从而可以合理调度多个频点(或阵面)的发射通道，提升系统容量。
在一种可能的实现方式中，该第一调度模式为通过多个频点中的不同频点对应的多个发射通道发射该多个第一波束的调度模式；该第二调度模式为通过该多个频点中的相同频点对应的多个发射通道发射该多个第二波束的调度模式；该第三调度模式为通过该多个频点对应的多个发射通道发射该第三波束的调度模式。基于上述方法，可以根据发射通道发射的波束的数量、发射通道对应的频点(或阵面)把调度模式划分为第一调度模式、第二调度模式和第三调度模式，以适应不同的场景。
在一种可能的实现方式中，该第一参数包括第一比特值，该第一比特值为采用该第一调度模式发射多个第一波束的情况下，通过该多个第一波束发送的数据包的大小；该第二参数包括第二比特值，该第二比特值为采用该第二调度模式发射多个第二波束的情况，通过该多个第二波束发送的数据包的大小；该第三参数包括第三比特值，该第三比特值为采用第三调度模式发射第三波束的情况下，通过该第三波束发送的数据包的大小。基于上述方法，可以根据每种调度模式下发送的数据包的大小，确定发射波束的调度模式，使得第一调度模式、第二调度模式和第三调度模式中，吞吐率性能较好的调度模式可以作为发射波束的调度模式，从而可以合理调度多个频点(或阵面)的发射通道，提升系统容量。
在一种可能的实现方式中，该第一比特值为采用该第一调度模式发射多个第一波束的情况下，通过N个第一波束发送的数据包的大小之和，N为正整数，通过第四波束发送给第一终端的数据包的大小小于或等于该第一终端对应的可用带宽能发送的数据包的大小，该第四波束为该N个第一波束中的任一波束，该第一终端为该第四波束对应的终端中的任一终端；或者，该第一比特值与该第三比特值相同。基于上述方法，可以获取到第一比特值。
在一种可能的实现方式中，该通过N个第一波束发送的数据包是根据该多个第一波束的优先级，和/或，该多个第一波束对应的多个终端的优先级确定的。基于上述方法，可以根据多个第一波束的优先级，和/或，多个第一波束对应的多个终端的优先级合理确定通过N个第一波束发送的数据包。
在一种可能的实现方式中，该第二比特值为采用该第二调度模式发射多个第二波束的情况下，通过M个第二波束发送的数据包的大小之和，M为正整数，通过第五波束发送给第二终端的数据包的大小小于或等于该第二终端对应的可用带宽能发送的数据包的大小，该第五波束为该M个第二波束中的任一波束，该第二终端为该第五波束对应的终端中的任一终端；或者，该第二比特值与该第三比特值相同。基于上述方法，可以获取到第二比特值。
在一种可能的实现方式中，该通过M个第二波束发送的数据包是根据该多个第二波束的优先级，和/或，该多个第二波束对应的多个终端的优先级确定的。基于上 述方法，可以根据多个第二波束的优先级，和/或，多个第二波束对应的多个终端的优先级合理确定通过M个第一波束发送的数据包。
在一种可能的实现方式中，该第三比特值为采用该第三调度模式发射第三波束的情况下，通过第三波束发送给P个终端的数据包的大小之和，通过第三波束发送给第三终端的数据包的大小小于或等于该第三终端对应的可用带宽能发送的数据包的大小，该第三终端为该P个终端中的任一终端。基于上述方法，可以获取到第三比特值。
在一种可能的实现方式中，该通过第三波束发送给P个终端的数据包是根据第三波束对应的终端的优先级确定的。基于上述方法，可以根据第三波束对应的终端的优先级合理确定通过第三波束发送给P个终端的数据包。
在一种可能的实现方式中，该发射波束的调度模式为该第一比特值、该第二比特值和该第三比特值中最大的比特值对应的调度模式。基于上述方法，可以将第一调度模式、第二调度模式和第三调度模式中，吞吐率性能较好的调度模式作为发射波束的调度模式，从而可以合理调度多个频点(或阵面)的发射通道，提升系统容量。
在一种可能的实现方式中，获取第一调度模式对应的第一参数之前，该方法还包括：获取在第一调度模式下的信号与干扰加噪声比SINR；获取第一调度模式对应的第一参数，包括：根据该第一调度模式下的SINR获取该第一参数。可以理解的，第一调度模式会引入功率损失和/或阵面增益损失，导致频谱效率降低。因此，基于上述方法，在确定第一参数之前，可以修正基于当前信道状态确定的SINR，再根据修正后的SINR确定第一参数，使得第一参数更为准确。
在一种可能的实现方式中，第一调度模式下的SINR为基于当前信道状态确定的SINR与损耗值之差，该损耗值为采用该第一调度模式发射该多个第一波束所引入的损耗。基于上述方法，可以通过损耗值修正基于当前信道状态确定的SINR，使得第一比特值更为准确。
在一种可能的实现方式中，第四终端对应的多个载波所属的频点相同，该第四终端包括在该多个第一波束对应的多个终端中；第五终端对应的多个载波所属的频点相同，该第五终端包括在该多个第二波束对应的多个终端中；第六终端对应的多个载波所属的频点相同，该第六终端包括在该第三波束对应的至少一个终端中。基于上述方法，可以优先将第四终端对应的多个载波、第五终端对应的多个载波或第六终端对应的多个载波分配在一个阵面内，以避免引入功率损失和/或阵面增益损失，导致频谱效率降低。

具体实施方式
首先，为了便于理解本申请实施例的技术方案，对本申请实施例涉及的技术术语进行解释说明。
1、波束(beam)
波束是一种通信资源，可以分为发送波束和接收波束。发送波束可以指信号经发射通道发射出去后在空间不同方向上形成的信号强度的分布，接收波束可以指从接收通道上接收到的无线信号在空间不同方向上的信号强度分布。在本申请实施例中，若未做出特别说明，波束是指发送波束。
可以理解的，AAU可以通过波束向至少一个终端发送数据包。向终端发送数据包的波束可以称为终端对应的波束。如图2所示，为AAU通过波束向终端发送数据包的示意图。在图2中，AAU 201可以通过波束202向终端204发送数据包，终端204对应的波束为波束202。AAU 201可以通过波束203向终端205和/或终端206发送数据包，终端205和/或终端206对应的波束为波束203。
2、调度模式
本申请实施例中的调度模式可以理解为调度多个阵面的发射通道发射波束的模式，或调度多个频点的发射通道发射波束的模式。本申请实施例中，不同阵面对应的频点不同，不同阵面对应的带宽的大小可以相同也可以不同，但是不同阵面对应的带宽不重叠。其中，阵面对应的频点可以为阵面对应的带宽的中心频点。在本申请实施例中，若没有特殊说明，频点指的是阵面对应的频点。
一种可能的实现方式，该调度模式可以分为三种类型，分别为第一调度模式、第二调度模式和第三调度模式。其中，第一调度模式和第二调度模式适用于多波束场景，第三调度模式适用于单波束场景。下面进行具体阐述。
第一调度模式为通过多个频点(或多个阵面)中的不同频点(或不同阵面)对应的多个发射通道发射多个第一波束的调度模式。也就是说，采用第一调度模式发射多个第一波束的情况下，发射多个第一波束的发射通道对应的频点(或阵面)不同。以图1所示的AAU发射两个波束为例，第一调度模式可以如图3A所示。在图3A中，AAU可以通过阵面0的TRX 0和TRX 1以及阵面1的TRX 4和TRX 5发射波束0，通过阵面0的TRX 2和TRX 3以及阵面1的TRX 6和TRX 7发射波束1。也就是说，AAU采用第一调度模式发射波束0和波束1的情况下，发射波束0的发射通道为阵面0的TRX 0和TRX 1以及阵面1的TRX 4和TRX 5，即发射波束0的多个发射通道对应的频点(或阵面)不同；发射波束1的发射通道为阵面0的TRX 2和TRX 3以及阵面1的TRX 6和TRX 7，即发射波束1的多个发射通道对应的频点(或阵面)不同。其中，阵面0的带宽为400MHz，阵面1的带宽为400MHz，波束0或波束1的带宽为800MHz。
可以理解的，若阵面0和阵面1有512个阵子，则波束0或波束1是通过阵面0和阵面1上的256个阵子发射的。这样会引入功率损失和/或阵面增益损失，导致频谱效率降低。但是，采用第一调度模式发射的第一波束的最大带宽能够达到多个阵面的带宽之和，第一波束的带宽较大。
第二调度模式为通过多个频点(或多个阵面)中的相同频点(或相同阵面)对应的多个发射通道发射多个第二波束的调度模式。也就是说，采用第二调度模式发射多个第二波束的情况下，发射多个第二波束的发射通道对应的频点(或阵面)相同。以图1所示的AAU发射两个波束为例，第二调度模式可以如图3B所示。在图3B中，AAU可以通过阵面0的TRX 0-TRX 3发射波束0，通过阵面1的TRX 4-TRX 7发射 波束1。也就是说，AAU采用第二调度模式发射波束0和波束1的情况下，发射波束0的发射通道为阵面0的TRX 0-TRX 3，即发射波束0的多个发射通道对应的频点(或阵面)相同；发射波束1的发射通道为阵面1的TRX 4-TRX 7，即发射波束1的多发射通道对应的频点(或阵面)相同。其中，阵面0的带宽为400MHz，阵面1的带宽为400MHz，波束0的带宽为400MHz，波束1的带宽为400MHz。
可以理解的，若阵面0和阵面1有512个阵子，则波束0是通过阵面0上的512个阵子发射的，波束1是通过阵面1上的512个阵子发射的，频谱效率较高。但是，与第一调度模式相比，采用第二调度模式发射的第二波束的最大带宽能够达到多个阵面中的任一个阵面的最大带宽，第二波束的带宽较小。
第三调度模式为通过多个频点(或阵面)对应的至少一个发射通道发射一个波束的调度模式。以图1所示的AAU发射两个波束为例，第三调度模式可以如图3C所示。在图3C中，AAU可以通过阵面0的TRX 0-TRX 3和阵面1的TRX 4-TRX 7发射波束0。其中，阵面0的带宽为400MHz，阵面1的带宽为400MHz，波束0的带宽为800MHz。可以理解的，若阵面0和阵面1有512个阵子，则波束0是通过阵面0和阵面1上的512个阵子发射的。
需要说明的是，在介绍上述第一调度模式、第二调度模式和第三调度模式的时候都是以图1所示的AAU为例进行阐述的，但这并不意味着本申请实施例的方案仅适用于图1所示的AAU。应理解，本申请实施例适用于由任意多阵面拼接的的装置，如由两个2T2R阵面拼接的装置、由两个8T8R阵面拼接的装置等。另外，本申请实施例也不限制拼接的阵面的数量、拼接的阵面的类型，如本申请实施例适用于由3个4T4R阵面拼接的装置、由一个4T4R阵面和一个8T8R阵面拼接的装置等。上述装置可以是AAU，也可以是远端射频单元(remote radio unit，RRU)。
下面结合附图对本申请实施例的实施方式进行详细描述。
本申请实施例提供的方法可用于各种通信系统。例如该通信系统可以为长期演进(long term evolution，LTE)系统、第五代(5th generation，5G)通信系统、第三代合作伙伴计划(3rd generation partnership project，3GPP)相关的通信系统、未来演进的通信系统、或多种系统融合的系统等，不予限制。其中，5G还可以称为新无线(new radio，NR)。下面以图4所示通信系统40为例，对本申请实施例提供的方法进行描述。
如图4所示，为本申请实施例提供的通信系统40的架构示意图。图4中，通信系统40可以包括一个或多个BBU 401(仅示出了1个)。可选的，通信系统40还包括AAU 402。BBU 401和AAU 402之间可以通过光纤、网线或者其他传输媒介连接。图4仅为示意图，并不构成对本申请提供的技术方案的适用场景的限定。
图4所示的BBU 401可以用于确定发射波束的调度模式。在一些实施例中，若发射的是单波束，则BBU 401确定发射波束的调度模式为第三调度模式。若发射的是多个波束，则BBU 401可以获取第一调度模式对应的第一参数，获取第二调度模式对应的第二参数，根据第一参数和第二参数，确定发射多个波束的调度模式。其中，第一参数为采用第一调度模式发射多个第一波束的情况下，通过多个第一波束发送的数据包的传输参数；第二参数为采用第二调度模式发射多个第二波束的情况下， 通过多个第二波束发送的数据包的传输参数。BBU 401获取第一参数和第二参数的过程可以参考后续图6所示的方法中所述。
在另一些实施例中，若发射的是单波束，则BBU 401确定发射波束的调度模式为第三调度模式。若发射的是多个波束，则BBU 401可以获取第一调度模式对应的第一参数，获取第二调度模式对应的第二参数，获取第三调度模式对应的第三参数，根据第一参数、第二参数和第三参数，确定发射波束的调度模式。其中，第三参数为采用第三调度模式发射第三波束的情况下，通过第三波束发送的数据包的传输参数。具体的，可以参考后续图6所示的方法中所述，在此不做赘述。
可选的，BBU 401确定了发射波束的调度模式后，可以通过与该确定的调度模式对应的端口向AAU 402发送信号。AAU 402通过与该确定的调度模式对应的端口接收到信号后，可以确定发射波束的调度模式，并采用该调度模式发射波束。

存储器503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期望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502与处理器501相耦合。存储器503也可以和处理器501集成在一起。本申请实施例提供的存储器通常可以具有非易失性。
其中，存储器503用于存储执行本申请实施例提供的方案所涉及的计算机执行指令，并由处理器501来控制执行。处理器501用于执行存储器503中存储的计算机执行指令，从而实现本申请实施例提供的方法。或者，可选的，本申请实施例中，也可以是处理器501执行本申请下述实施例提供的方法中的处理相关的功能，通信接口504负责与其他设备或通信网络通信，本申请实施例对此不作具体限定。

其中，BBU可以为图4所示的BBU 401。第一调度模式的介绍可以参考上述对本申请实施例涉及的技术术语的描述，在此不做赘述。第一参数为采用第一调度模式发射多个第一波束的情况下，通过多个第一波束发送的数据包的传输参数。
一种可能的实现方式，第一参数包括第一比特值。第一比特值为采用第一调度模式发射多个第一波束的情况下，通过多个第一波束发送的数据包的大小。例如，第一比特值为采用第一调度模式发射多个第一波束的情况下，通过多个第一波束发送的数据包对应的传输块大小(transport block size，TBS)。可以理解的，上述第一参数包括的内容仅是示例性的，在具体应用中，第一参数可以包括各种类型的传输参数，例如，第一参数可以包括第一比特值，和/或，第一时延信息。其中，第一时延信息用于指示采用第一调度模式发射多个第一波束的情况下，通过多个第一波束发送的数据包的时延。本申请实施例以第一参数包括第一比特值为例进行描述。
其中，上述数据包可以为向多个终端发送的数据包。通过第一波束可以向至少一个终端发送数据包，至少一个终端可以称为第一波束对应的终端。
一种可能的实现方式，第四终端对应的多个载波所属的频点(或阵面)相同。其中，第四终端包括在多个第一波束对应的多个终端中。也就是说，可以优先将第四终端对应的多个载波分配在一个阵面内，以避免引入功率损失和/或阵面增益损失，导致频谱效率降低。第四终端对应的多个载波为第四终端对应的第一波束的候选频域资源。
示例性的，如图7所示，为载波分配示意图。在图7中，阵面0对应的载波为载波0和载波1，阵面1对应的载波为载波2和载波3，则第四终端对应的多个载波包括载波0和载波1，或者，第四终端对应的多个载波包括载波2和载波3。
可以理解的，如前文所述，第一调度模式会引入功率损失和/或阵面增益损失，导致频谱效率降低，因此，在确定第一参数之前，BBU可以修正基于当前信道状态确定的SINR，再根据修正后的SINR确定第一参数，使得第一参数更为准确。
可选的，S601之前，BBU获取在第一调度模式下的信号与干扰加噪声比(signal  to interference plus noise ratio，SINR)。在这种情况下，BBU获取第一调度模式对应的第一参数，包括：BBU根据第一调度模式下的SINR获取第一参数。其中，第一调度模式下的SINR为基于当前信道状态确定的SINR与损耗值之差。损耗值为采用第一调度模式发射多个第一波束所引入的损耗。例如，该损耗值可以包括功率损失和/或阵面增益损失。
作为一种示例，若功率损失为3dB，阵面增益损失为3dB，则第一调度模式下的SINR＝基于当前信道状态确定的SINR-3dB-3dB。后续，BBU可以根据第一调度模式下的SINR查表确定第一波束对应的终端的调制与编码策略(modulation and coding scheme，MCS)，根据该MCS和该终端对应的可用带宽能发送的数据包的大小，确定第一调度模式下能够向该终端发送的数据包的大小，例如，确定第一调度模式下能够向该终端发送的数据包对应的TBS，进而可以确定第一比特值。
一种可能的实现方式，第一比特值为采用第一调度模式发射多个第一波束的情况下，通过N个第一波束发送的数据包的大小之和。或者，第一比特值与第三比特值相同。
其中，N为正整数，并且N小于或等于第一调度模式下配置的波束的最大个数。该最大个数可以是用户设置的，也可以是系统配置的，不予限制。通过第四波束发送给第一终端的数据包的大小小于或等于第一终端对应的可用带宽能发送的数据包的大小。其中，第四波束为N个第一波束中的任一波束，第一终端为第四波束对应的终端中的任一终端。
可以理解的，在通过多个第一波束发送数据包的过程中，可以逐一确定多个第一波束对应的多个终端的待发送数据包是否可以发送。在确定任一终端的待发送数据包是否可以发送时，可以根据该终端对应的MCS和当前的可用带宽(即该终端对应的可用带宽)能发送的数据包的大小确定的。任一终端的待发送数据包可以理解为需要发送给该终端的数据包。
一种可能的实现方式，通过N个第一波束发送的数据包是根据多个第一波束的优先级，和/或，多个第一波束对应的多个终端的优先级确定的。例如，多个第一波束的优先级、多个第一波束对应的多个终端的优先级可以如图8所示。在图8中，波束1的优先级高于波束2的优先级。对于波束1，终端1的优先级高于终端2的优先级。对于波束2，终端3的优先级高于终端4的优先级。
示例性的，以图8所示的多个第一波束的优先级、多个第一波束对应的多个终端的优先级为例，若当前仅能够发射一个波束，则优先发射波束1。若波束1仅能够向一个终端发送数据包，则优先向终端1发送数据包。
示例性的，可以将多个第一波束中、优先级最高的N个波束确定为N个第一波束。应理解，在具体实现中N个第一波束还可以是根据其他规则确定的，例如，N个第一波束为多个第一波束中、标识最小(或最大)的N个波束。
示例性的，以多个第一波束包括波束0和波束1，波束0的优先级大于波束1的优先级，波束0对应的终端为终端0，波束1对应的终端为终端1和终端2，终端1的优先级高于终端2的优先级为例。BBU首先根据终端0对应的MCS和当前的可用带宽(即终端0对应的可用带宽)能发送的数据包的大小确定终端0的待发送数据包 是否能发送。若当前不需要调度除终端0的待发送数据包之外的数据包，则当前的可用带宽(即终端0对应的可用带宽)为发射波束的装置(如AAU)的最大带宽。若终端0的待发送数据包的大小大于或等于当前的可用带宽(即终端0对应的可用带宽)能发送的数据包的大小，则通过波束0向终端0发送的数据包的大小为当前的可用带宽(即终端0对应的可用带宽)能发送的数据包的大小。在这种情况下，通过波束0不能发送终端0的待发送数据包，或者虽然可以通过波束0发送终端0的待发送数据包，但是没有多余的带宽能分配给波束1了。所以在这种情况下可以采用第三调度模式发送需要通过多个第一波束发送的数据包，因此，第一比特值和第三比特值相同。后续，若在S604中确定了发射波束的调度模式为第一调度模式，实际上是采用第三调度模式发射波束。第三比特值的获取方式可以参考后续S603中的描述。
若终端0的待发送数据包的大小小于当前的可用带宽(即终端0对应的可用带宽)能发送的数据包的大小，则通过波束0向终端0发送的数据包的大小为终端0的待发送数据包的大小。在这种情况下，通过波束0能发送终端0的待发送数据包，并且通过波束0发送了终端0的待发送数据包后，还有多余的带宽能分配给波束1。接着可以根据终端1对应的MCS和当前的可用带宽(即终端1对应的可用带宽)能发送的数据包的大小确定终端1的待发送数据包是否能发送。其中，当前的可用带宽(即终端1对应的可用带宽)为通过波束0发送了终端0的待发送数据包后的剩余带宽。若终端1的待发送数据包的大小大于或等于当前的可用带宽(即终端1对应的可用带宽)能发送的数据包的大小，则通过波束1向终端1发送的数据包的大小为当前的可用带宽(即终端1对应的可用带宽)能发送的数据包的大小。在这种情况下，通过波束1不能发送终端1的待发送数据包，或者虽然可以通过波束1发送终端1的待发送数据包，但是没有多余的带宽能分配给波束1对应的终端2了。在这种情况下，第一比特值为通过波束0向终端0发送的数据包的大小，与通过波束1向终端1发送的数据包的大小之和，例如，第一比特值＝TBSB0+TBSB1-1。其中，TBSB0为通过波束0向终端0发送的数据包对应的TBS。TBSB1-1为通过波束1向终端1发送的数据包对应的TBS。
若终端1的待发送数据包的大小小于当前的可用带宽(即终端1对应的可用带宽)能发送的数据包的大小，则通过波束1向终端1发送的数据包的大小为终端1的待发送数据包的大小。在这种情况下，通过波束0能发送终端0的待发送数据包，通过波束1也能发送终端1的待发送数据包，并且通过波束0发送了终端0的待发送数据包，以及通过波束1发送了终端1的待发送数据包后，还有多余的带宽能分配给波束1对应的终端2。接着可以根据终端2对应的MCS和当前的可用带宽(即终端2对应的可用带宽)能发送的数据包的大小确定终端2的待发送数据包是否能发送。其中，当前的可用带宽(即终端2对应的可用带宽)为通过波束0发送了终端0的待发送数据包，以及通过波束1发送了终端1的待发送数据包后的剩余带宽。若终端2的待发送数据包的大小大于或等于当前的可用带宽(即终端2对应的可用带宽)能发送的数据包的大小，说明通过波束1不能发送终端2的待发送数据包，则通过波束1向终端2发送的数据包的大小为当前的可用带宽(即终端12对应的可用带宽)能发送的数据包的大小。在这种情况下，第一比特值为通过波束0向终端0发送的数据包的 大小，通过波束1向终端1发送的数据包的大小以及通过波束1向终端2发送的数据包的大小之和，例如，第一比特值＝TBSB0+TBSB1-1+TBSB1-2。其中，TBSB1-2为通过波束1向终端2发送的数据包对应的TBS。若终端2的待发送数据包的大小小于当前的可用带宽(即终端2对应的可用带宽)能发送的数据包的大小，说明通过波束1能发送终端2的待发送数据包，则通过波束1向终端2发送的数据包的大小为终端2的待发送数据包的大小。在这种情况下，第一比特值为通过波束0向终端0发送的数据包的大小，通过波束1向终端1发送的数据包的大小以及通过波束1向终端2发送的数据包的大小之和，例如，第一比特值＝TBSB0+TBSB1-1+TBSB1-2。
一种可能的实现方式，若通过第六波束发送的数据包的大小大于或等于第一阈值，则第一比特值与第三比特值相同。若通过第六波束发送的数据包的大小小于第一阈值，则第一比特值为采用第一调度模式发射多个第一波束的情况下，通过N个第一波束发送的数据包的大小之和。其中，BBU可以首先确定多个第一波束中的第六波束对应的终端的待发送数据包是否可以发送。或者说，第六波束为多个第一波束中，BBU首先确定数据包是否可以发送的波束。例如，第六波束为多个第一波束中、优先级最高的波束。
可以理解的，若通过第六波束发送的数据包的大小大于或等于第一阈值，说明通过第六波束发送的数据包的大小较大，在这种情况下，若采用第一调度模式发送数据包可能会导致数据包丢失。因此，可以采用第三调度模式发送数据包。若通过第六波束发送的数据包的大小小于第一阈值，说明通过第六波束发送的数据包的大小较小，可以采用第一调度模式发送数据包。
示例性的，第一阈值可以为第一调度模式下发射波束的装置(如AAU)的最大带宽能发送的数据包的大小的60％或70％。第一调度模式下发射波束的装置(如AAU)的最大带宽能够达到发射波束的装置(如AAU)的多个阵面的带宽之和。
S602：BBU获取第二调度模式对应的第二参数。
其中，第二调度模式的介绍可以参考上述对本申请实施例涉及的技术术语的描述，在此不做赘述。第二参数为采用第二调度模式发射多个第二波束的情况下，通过多个第二波束发送的数据包的传输参数。
一种可能的实现方式，第二参数包括第二比特值。第二比特值为采用第二调度模式发射多个第二波束的情况下，通过多个第二波束发送的数据包的大小。例如，第二比特值为采用第二调度模式发射多个第二波束的情况下，通过多个第二波束发送的数据包对应的TBS。可以理解的，上述第二参数包括的内容仅是示例性的，在具体应用中，第二参数可以包括各种类型的传输参数，例如，第二参数可以包括第二比特值，和/或，第二时延信息。其中，第二时延信息用于指示采用第二调度模式发射多个第二波束的情况下，通过多个第二波束发送的数据包的时延。本申请实施例以第二参数包括第二比特值为例进行描述。
其中，S602中的数据包可以为向多个终端发送的数据包。通过第二波束可以向至少一个终端发送数据包，至少一个终端可以称为第二波束对应的终端。
一种可能的实现方式，第五终端对应的多个载波所属的频点(或阵面)相同。其中，第五终端包括在多个第二波束对应的多个终端中。也就是说，可以优先将第五终 端对应的多个载波分配在一个阵面内，以避免引入功率损失和/或阵面增益损失，导致频谱效率降低。第五终端对应的多个载波为第五终端对应的第二波束的候选频域资源。
可以理解的，S602之前，BBU可以根据基于当前信道状态确定的SINR查表确定第二波束对应的终端的MCS，根据该MCS和该终端对应的可用带宽能发送的数据包的大小，确定第二调度模式下能够向该终端发送的数据包的大小，例如，确定第二调度模式下能够向该终端发送的数据包对应的TBS，进而可以确定第二比特值。
一种可能的实现方式，第二比特值为采用第二调度模式发射多个第二波束的情况下，通过M个第二波束发送的数据包的大小之和。或者，第二比特值与第三比特值相同。
其中，M为正整数，并且M小于或等于第二调度模式下配置的波束的最大个数。该最大个数可以是用户设置的，也可以是系统配置的，不予限制。第二调度模式下配置的波束的最大个数与第一调度模式下配置的波束的最大个数相同或不同。通过第五波束发送给第二终端的数据包的大小小于或等于第二终端对应的可用带宽能发送的数据包的大小。其中，第五波束为M个第二波束中的任一波束，第二终端为第五波束对应的终端中的任一终端。
可以理解的，在通过多个第二波束发送数据包的过程中，可以逐一确定多个第二波束对应的多个终端的待发送数据包是否可以发送。在确定任一终端的待发送数据包是否可以发送时，可以根据该终端对应的MCS和当前的可用带宽(即该终端对应的可用带宽)能发送的数据包的大小确定的。任一终端的待发送数据包可以理解为需要发送给该终端的数据包。
可以理解的，通过多个第二波束发送数据包的过程与通过多个第一波束发送数据包的过程类似，因此可以参考S601中对应的描述。不同的是，第二调度模式下发射波束的装置(如AAU)的最大带宽，与第一调度模式下发射波束的装置(如AAU)的最大带宽不同。第二调度模式下发射波束的装置(如AAU)的最大带宽能够达到发射波束的装置(如AAU)的多个阵面中的任一个阵面的最大带宽。第一调度模式下发射波束的装置(如AAU)的最大带宽能够达到发射波束的装置(如AAU)的多个阵面的带宽之和。明显的，第二调度模式下发射波束的装置(如AAU)的最大带宽，小于第一调度模式下发射波束的装置(如AAU)的最大带宽。
一种可能的实现方式，通过M个第二波束发送的数据包是根据多个第二波束的优先级，和/或，多个第二波束对应的多个终端的优先级确定的。例如，可以将多个第二波束中、优先级最高的M个波束确定为M个第二波束。应理解，在具体实现中M个第二波束还可以是根据其他规则确定的，例如，M个第二波束为多个第二波束中、标识最小(或最大)的M个波束。
一种可能的实现方式，若通过第七波束发送的数据包的大小大于或等于第二阈值，则第二比特值与第三比特值相同。若通过第七波束发送的数据包的大小小于第二阈值，则第二比特值为采用第二调度模式发射多个第二波束的情况下，通过M个第二波束发送的数据包的大小之和。其中，BBU可以首先确定多个第二波束中的第七波束对应的终端的待发送数据包是否可以发送。或者说，第七波束为多个第二波束 中，BBU首先确定数据包是否可以发送的波束。例如，第七波束为多个第二波束中、优先级最高的波束。
可以理解的，若通过第七波束发送的数据包的大小大于或等于第二阈值，说明通过第七波束发送的数据包的大小较大，在这种情况下，若采用第二调度模式发送数据包可能会导致数据包丢失。因此，可以采用第三调度模式发送数据包。若通过第七波束发送的数据包的大小小于第二阈值，说明通过第七波束发送的数据包的大小较小，可以采用第二调度模式发送数据包。
示例性的，第二阈值可以为第二调度模式下发射波束的装置(如AAU)的最大带宽能发送的数据包的大小的50％。
S603：BBU获取第三调度模式对应的第三参数。
其中，第三调度模式的介绍可以参考上述对本申请实施例涉及的技术术语的描述，在此不做赘述。第三参数为采用第三调度模式发射第三波束的情况下，通过第三波束发送的数据包的传输参数。
一种可能的实现方式，第三参数包括第三比特值。第三比特值为采用第三调度模式发射第三波束的情况下，通过第三波束发送的数据包的大小。例如，第三比特值为采用第三调度模式发射第三波束的情况下，通过第三波束发送的数据包对应的TBS。可以理解的，上述第三参数包括的内容仅是示例性的，在具体应用中，第三参数可以包括各种类型的传输参数，例如，第三参数可以包括第三比特值，和/或，第三时延信息。其中，第三时延信息用于指示采用第三调度模式发射第三波束的情况下，通过第三波束发送的数据包的时延。本申请实施例以第三参数包括第三比特值为例进行描述。
其中，S603中的数据包可以为向至少一个终端发送的数据包。至少一个终端可以称为第三波束对应的终端。
一种可能的实现方式，第六终端对应的多个载波所属的频点相同。第六终端包括在第三波束对应的至少一个终端中。也就是说，可以优先将第六终端对应的多个载波分配在一个阵面内，以避免引入功率损失和/或阵面增益损失，导致频谱效率降低。第六终端对应的多个载波为第三波束的候选频域资源。
可以理解的，S603之前，BBU可以根据基于当前信道状态确定的SINR查表确定第三波束对应的终端的MCS，根据该MCS和该终端对应的可用带宽能发送的数据包的大小，确定第三调度模式下能够向该终端发送的数据包的大小，例如，确定第三调度模式下能够向该终端发送的数据包对应的TBS，进而可以确定第三比特值。
一种可能的实现方式，第三比特值为采用第三调度模式发射第三波束的情况下，通过第三波束发送给P个终端的数据包的大小之和。其中，通过第三波束发送给第三终端的数据包的大小小于或等于第三终端对应的可用带宽能发送的数据包的大小，第三终端为P个终端中的任一终端。P为正整数。
可以理解的，在通过第三波束发送数据包的过程中，可以逐一确定第三波束对应的至少一个终端的待发送数据包是否可以发送。在确定任一终端的待发送数据包是否可以发送时，可以根据该终端对应的MCS和当前的可用带宽(即该终端对应的可用带宽)能发送的数据包的大小确定的。任一终端的待发送数据包可以理解为需要发送 给该终端的数据包。
可以理解的，通过第三波束发送数据包的过程与通过多个第一波束发送数据包的过程类似，因此可以参考S601中对应的描述。不同的是，通过第三波束发送数据包的过程中，逐一确定一个波束对应的至少一个终端的待发送数据包是否可以发送。通过多个第一波束发送数据包的过程中，逐一确定多个波束对应的多个终端的待发送数据包是否可以发送。

S604：BBU根据第一参数、第二参数和第三参数，确定发射波束的调度模式。
一种可能的实现方式，若第一参数包括第一比特值，第二参数包括第二比特值，第三参数包括第三比特值，则发射波束的调度模式为第一比特值、第二比特值和第三比特值中最大的比特值对应的调度模式。也就是说，BBU可以将第一调度模式、第二调度模式和第三调度模式中，吞吐率性能较好的调度模式确定为发射波束的调度模式，以提升系统容量。
一种可能的实现方式，若第一参数包括第一时延信息，第二参数包括第二时延信息，第三参数包括第三时延信息，则发射波束的调度模式为第一时延信息、第二时延信息和第三时延信息中最小的时延信息对应的调度模式。也就是说，BBU可以将第一调度模式、第二调度模式和第三调度模式中，时延较小的调度模式确定为发射波束的调度模式，以降低传输时延，提高用户体验。
一种可能的实现方式，若第一参数包括第一时延信息和第一比特值，第二参数包括第二时延信息和第二比特值，第三参数包括第三时延信息和第三比特值，则发射波束的调度模式为时延信息小于或等于第三阈值，并且比特值大于或等于第四阈值的调度模式。也就是说，BBU可以将第一调度模式、第二调度模式和第三调度模式中，时延较小并且吞吐率性能较好的调度模式确定为发射波束的调度模式，以降低传输时延，提高用户体验，并提升系统容量。
可以理解的，若根据上述过程确定的发射波束的调度模式有多个，则可以进一步根据预设规则确定发射波束的调度模式。例如，可以将第一调度模式、第二调度模式和第三调度模式中标识最小(或标识最大)的调度模式确定为发射波束的调度模式。又例如，若第一比特值、第二比特值和第三比特值中最大的比特值对应的调度模式包括最近一次确定的发射波束的调度模式，可以将最近一次确定的发射波束的调度模式确定为本次发射波束的调度模式，以避免调度模式的频繁切换。又例如，若第一比特值、第二比特值和第三比特值中最大的比特值对应的调度模式有多个，可以进一步根据时延信息确定发射波束的调度模式。又例如，若第一时延信息、第二时延信息和第 三时延信息中最小的时延信息对应的调度模式有多个，可以进一步根据比特值确定发射波束的调度模式。
基于图6所示的方法，BBU可以获取第一调度模式对应的第一参数，第二调度模式对应的第二参数，第三调度模式对应的第三参数，并根据第一参数、第二参数和第三参数确定发射波束的调度模式，使得第一调度模式、第二调度模式和第三调度模式中，吞吐率性能较好的调度模式可以作为发射波束的调度模式，从而可以合理调度多个频点(或阵面)的发射通道，提升系统容量。
其中，上述S601-S604中的BBU的动作可以由图5所示的通信装置50中的处理器501调用存储器503中存储的应用程序代码来执行，本申请实施例对此不做任何限制。
可以理解的，以上各个实施例中，由BBU实现的方法和/或步骤，也可以由可用于BBU的部件(例如芯片或者电路)实现。
