一种通信方法及装置
相关申请的交叉引用
本申请要求在2021年08月18日提交中国专利局、申请号为202110951071.X、申请名称为“一种通信方法及装置”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
本申请涉及通信技术领域，尤其涉及一种通信方法及装置。
背景技术
在无线通信系统中，终端设备在完成小区搜索过程、并和小区取得下行同步之后，需要通过系统信息(system information，SI)确定系统帧号以及子载波间隔等信息。在第五代(5th generation，5G)新无线(new radio，NR)系统中，系统信息包括以下三种：主系统消息块(master information block，MIB)，系统消息块1(system information block 1，SIB1)和其他系统信息(other system information，OSI)。其中OSI是指从除了MIB和SIB1外的其他系统信息，例如OSI可以包括SIB2至SIB14。MIB和SIB1也可以称为最小系统信息(minimum SI)，SIB1也可以称为剩余最小系统信息(remaining minimum SI，RMSI)。
SIB1是以广播方式发送的，基站需要在各个波束(beam)方向上发送SIB1，消耗更多的系统资源。为了减少资源消耗，NR中引入基于需求的调度(on-demand调度)方式。对于采用基于需求的调度方式的SI，终端设备需要接收SI时，发起SI请求(request)，向基站请求发送对应的SI。如果基站给终端设备配置了专用的随机接入资源，那么终端设备在消息1(message 1，Msg1)上发送SI request，否则在消息3(message 3，Msg3)中发送SI request。当基站接收到Msg1或Msg3中的SI request后，在SI对应的SI窗口(SI-window)中调度SI。
当前OSI的调度方式，是由基站侧静态配置的，也就是说，基站的维护人员可以根据实际情况将OSI的调度方式配置为基于广播的调度方式或者基于需求的调度方式。一方面，如果OSI中的一个SIB被配置为基于广播的调度方式，但是实际需要接收该SIB的终端设备的数量较少，那么会导致资源浪费。另一方面，如果OSI中的一个SIB被配置为基于需求的调度方式，但是实际需要接收该SIB的终端设备的数量较多，那么导致大量的终端设备请求该SIB，带来了大量的信令开销，以及导致终端设备接入成功率降低。
综上所述，如何较优的配置OSI的调度方式，是一个亟待解决的问题。

本申请实施例中所涉及到的网络设备，可以是RAN中的基站(如下一代基站(generation Node B，gNB))等。如图1所示，基站可以是集中式单元(centralized unit，CU)和分布式单元(distributed unit,DU)分离架构。RAN可以与核心网相连(例如可以是长期演进(long term evolution，LTE)的核心网，也可以是5G的核心网等)。CU和DU可以理解为是对基站从逻辑功能角度的划分。CU和DU在物理上可以是分离的也可以部 署在一起。多个DU可以共用一个CU。一个DU也可以连接多个CU(图中未示出)。CU和DU之间可以通过接口相连，例如可以是F1接口。CU和DU可以根据无线网络的协议层划分。例如其中一种可能的划分方式是：CU用于执行无线资源控制(radio resource control，RRC)层、业务数据适配协议(service data adaptation protocol，SDAP)层以及分组数据汇聚层协议(packet data convergence protocol，PDCP)层的功能，而DU用于执行无线链路控制(radio link control，RLC)层，媒体接入控制(media access control，MAC)层，物理(physical)层等的功能。可以理解对CU和DU处理功能按照这种协议层的划分仅仅是一种举例，也可以按照其他的方式进行划分。例如可以将CU或者DU划分为具有更多协议层的功能。例如，CU或DU还可以划分为具有协议层的部分处理功能。在一设计中，将RLC层的部分功能和RLC层以上的协议层的功能设置在CU，将RLC层的剩余功能和RLC层以下的协议层的功能设置在DU。在另一种设计中，还可以按照业务类型或者其他系统需求对CU或者DU的功能进行划分。例如按时延划分，将处理时间需要满足时延要求的功能设置在DU，不需要满足该时延要求的功能设置在CU。在另一种设计中，CU也可以具有核心网的一个或多个功能。一个或者多个CU可以集中设置，也分离设置。例如CU可以设置在网络侧方便集中管理。DU可以具有多个射频功能，也可以将射频功能拉远设置。
CU的功能可以由一个实体来实现也可以由不同的实体实现。例如，可以对CU的功能进行进一步切分，例如，将控制面(control plane，CP)和用户面(user plane，UP)分离，即CU的控制面(CU-CP)和CU用户面(CU-UP)。例如，CU-CP和CU-UP可以由不同的功能实体来实现，并通过E1接口相连，CU-CP和CU-UP可以与DU相耦合，共同完成基站的功能。
本申请实施例适用于终端设备初始接入基站的小区时，如何获取OSI的场景。目前，一个SI消息包含哪些SIB是通过SIB1中的SI调度信息(si-SchedulingInfo)指定的，SI调度信息还指示OSI的调度方式。本申请实施例中，终端设备和基站中的小区取得下行同步之后，可以接收SIB1，并根据该SIB1确定OSI的调度方式，从而按照相应的调度方式获取OSI。OSI是指从除了MIB和SIB1外的其他系统信息，例如，在NR系统中，OSI包括SIB2至SIB14中的至少一个。
OSI中的SIB的调度方式可以包括基于需求的调度方式和基于广播的调度方式。
在基于需求的调度方式下，终端设备可以通过随机接入过程中的消息1或消息3，向基站请求OSI中的SIB。如果通过消息1请求该SIB，基站会预先配置SIB和前导码(preamble)的对应关系，并通知给终端设备，终端设备在随机接入过程中发送所请求的SIB对应的前导码，就可以请求相应的SIB。如果通过消息3请求SIB，终端设备在随机接入过程中的消息3发送所请求的SIB的编号，例如编号为2，则终端设备请求的是SIB2，如此就可以请求相应的SIB。另外，OSI中的SIB是通过SI消息携带的，一个SIB只包含在一个SI消息中，因此终端设备可以通过发起SI请求来获取SIB。在该调度方式下，如果实际需要接收该SIB的终端设备的数量较多，那么导致大量的终端设备请求该SIB，带来了大量的信令开销，以及导致终端设备通过请求方式请求系统信息块对其他终端设备随机接入造成影响，使得终端设备接入成功率降低。
在基于广播的调度方式下，基站通过广播方式发送OSI中的SIB。在该调度方式下，无论是否存在需要该SIB的终端设备，都需要按照一定周期广播该SIB，需要消耗较多的 资源。
因此，如何配置OSI中SIB的调度方式，使得资源利用率和终端设备接入成功率之间实现较优的平衡，是一个亟待解决的问题。
本申请实施例中，将人工智能(artificial intelligence，AI)技术和OSI中SIB的调度方式结合起来，通过基于AI对终端设备对OSI中SIB需求的预测，推理出合理的OSI中SIB的调度方式。本申请还可以在不同的时间段，对OSI中SIB实行不同的调度方式，满足不同时段终端设备对OSI中SIB的需求，从而减少时频资源的浪费，以及降低SI请求时，终端设备的接入成功率降低。为了描述方便，本申请实施例以下的描述中，出现的“SIB”或“系统信息块”，如果没有明确说明，可以是指除了MIB和SIB1外的SIB，即OSI中的SIB。
为了便于理解，首先对AI技术进行介绍。可以理解的是，该介绍并不作为对本申请实施例的限定。AI，是一种通过模拟人脑进行复杂计算的技术。随着数据存储和能力的能升，AI得到了越来越多的应用。第三代合作伙伴计划(3 rd generation partnership project，3GPP)的版本17(release17，R17)通过了研究项目(study item，SI)，提出将AI运用到NR中。
如图2所示为AI在通信系统中的第一种应用框架的示例图。其中，数据源(data source)用于存储训练数据和推理数据。模型训练节点(model trainning host)通过对数据源提供的训练数据(training data)进行分析或训练，得到AI模型，且将AI模型部署在模型推理节点(model inference host)中。模型推理节点使用AI模型，基于数据源提供的推理数据进行推理，得到推理结果。该推理结果用于对网络运行给出基于AI的合理预测，或者指导网络做出策略配置或策略调整。相关的策略配置或者策略调整，由执行(actor)实体统一规划，并发送给多个执行对象(例如，网络实体)去执行。同时，应用了相关策略后，网络的具体表现，可以被再次输入到数据源存储起来。

图3中，第一AI模块独立于基站，第一AI模块通过对训练数据进行分析或训练，得到AI模型。针对某个参数，可以是第一AI模块利用相应的AI模型和推理数据进行推理，得到该参数。图3中，第一AI模块的推理数据可以是来自基站、CU、CU-CP、CU-UP、DU、UE和/或其它实体的数据。第一AI模块的推理结果可以被发送给基站、CU、CU-CP、CU-UP、DU或UE等，用于进行策略配置或策略调整。用于推理不同参数的AI模型可以是相同的，也可以是不同的，不予限制。
其它实体包括但不限于追踪收集实体(trace collection entity，TCE)、用户面功能(User Plane Function，UPF)、接入和移动性管理功能(access and mobility management function,AMF)等。
图4中，第一AI模块独立于基站，第二AI模块位于基站内。通过训练数据对第一AI模型进行训练后，可以由第一AI模块将第一AI模型的信息发送给位于基站中(或描述为位于RAN中)的第二AI模块，由第二AI模块利用相应的AI模型和推理数据进行推理，得到推理结果。图4中，第二AI模块的推理数据可以是来自基站、CU、CU-CP、CU-UP、DU、UE和/或其它实体的数据。第二AI模块的推理结果可以被发送给基站、CU、CU-CP、CU-UP、DU或UE等。
图5中，第二AI模块位于基站内，基站中的第二AI模块用于推理AI模型，即 第二AI模块接收训练数据，并通过对该训练数据进行训练。第二AI模块可以利用推理数据进行推理，得到推理结果。图5中，第二AI模块的推理数据可以是来自基站、CU、CU-CP、CU-UP、DU、UE和/或其它实体的数据。第二AI模块的推理结果可以被发送给基站、CU、CU-CP、CU-UP、DU或UE等。
需要说明的是，在上述图3至图5的框架中，AI模型可以简称为模型，其可以看做是从输入的信息到输出的信息之间的映射。输入的信息可以包括一个或多个信息，输出的信息可以包括一个或多个信息。训练数据用于训练AI模型。训练数据可以是来自基站、CU、CU-CP、CU-UP、DU、UE和/或其它实体的数据，和/或是通过AI技术推理出的数据，不予限制。推理数据包括输入测量量，用于利用模型推理出参数。
可以理解的是，本申请实施例中，AI设备或基站可以执行本申请实施例中的部分或全部步骤，这些步骤或操作仅是示例，本申请实施例还可以执行其它操作或者各种操作的变形。AI设备可以为包括图2所示结构的设备。AI设备还可以称为AI节点或AI实体等，不作限定。此外，各个步骤可以按照本申请实施例呈现的不同的顺序来执行，并且有可能并非要执行本申请实施例中的全部操作。
在本申请的各个实施例中，如果没有特殊说明以及逻辑冲突，不同的实施例之间的术语和/或描述具有一致性、且可以相互引用，不同的实施例中的技术特征根据其内在的逻辑关系可以组合形成新的实施例。
可以理解的是，在本申请的实施例中涉及的各种数字编号仅为描述方便进行的区分，并不用来限制本申请的实施例的范围。上述各过程的序号的大小并不意味着执行顺序的先后，各过程的执行顺序应以其功能和内在逻辑确定。
本申请实施例描述的网络架构以及业务场景是为了更加清楚的说明本申请实施例的技术方案，并不构成对于本申请实施例提供的技术方案的限定，本领域普通技术人员可知，随着网络架构的演变和新业务场景的出现，本申请实施例提供的技术方案对于类似的技术问题，同样适用。
如图6所示，为本申请实施例提供的一种通信方法流程示意图，该流程中，以AI设备独立于网络设备为例进行描述，AI设备也可以位于网络设备的CU或DU中，还可以位于操作管理和维护(operation administration andmaintenance，OAM)设备，也可以独立作为一个模块位于网络设备或核心网侧。该方法包括：
S601：AI设备获取第二信息、第三信息以及第四信息中的至少一项。
其中，上述第二信息、第三信息以及第四信息中的至少一项，为AI设备推理系统信息块的调度方式所需要的输入信息。第二信息、第三信息以及第四信息可以直接作为推理功能的输入信息，也可以由AI设备经过运算等处理后作为推理功能的输入信息，不做限定。
本申请实施例中，第二信息可以指示期望获取系统信息块的终端设备的数量，图6所示的流程中的系统信息块可以是指OSI，例如为SIB2至SIB14中的任一项。另外，为了描述方便，这里仅以一个系统信息块为例进行描述，本申请实施例中，AI设备可以获取N个系统信息块对应的第二信息，即N个系统信息块中的一个系统信息块对应一个第二信息，第二信息指示出期望获取与该第二信息对应的系统信息块的终端设备的数量，N为大于0的整数。这里的终端设备，可以是指位于网络设备的小区内的终端设备。AI设备可以获取网络设备的小区内多个终端设备的最小化路测(minimization of drive test,MDT)数据，MDT 数据可以指示终端设备期望获取的系统信息块的编号，也就是说终端设备期望获得哪些系统信息块，可以通过MDT上报。
AI设备具体如何获取MDT数据，本申请并不限定，例如，AI设备可以通过追踪收集实体(trace collection entity，TCE)获取多个终端设备的MDT数据。一种实现方式中，AI设备可以主动向TCE请求终端设备的MDT数据；另一种实现方式中，TCE可以周期性的向AI设备上报终端设备的MDT数据，本申请实施例对此并不限定。
AI设备可以通过终端设备的MDT数据确定该终端设备期望获取的系统信息块，从而可以确定网络设备的小区内，期望获取各个系统信息块的终端设备的数量。
举例来说，AI设备获取到m个MDT数据，假设m个MDT数据分别指示期望获取的系统信息块如下：
终端设备1对应的MDT数据指示期望获取的系统信息块：SIB2,SIB10；
终端设备2对应的MDT数据指示期望获取的系统信息块：SIB3,SIB4,SIB9,SIB11；
终端设备3对应的MDT数据指示期望获取的系统信息块：SIB2,SIB5,SIB6；
……
终端设备m对应的MDT数据指示期望获取的系统信息块：SIB6,SIB9,SIB12,SIB13。
根据m个MDT数据，可以确定出期望获取每个系统信息块的终端设备的数量，例如可以如下所示：
期望获取SIB2的终端设备的数量：22；期望获取SIB3的终端设备的数量：12；
期望获取SIB4的终端设备的数量：5；期望获取SIB5的终端设备的数量：11；
期望获取SIB6的终端设备的数量：6；期望获取SIB7的终端设备的数量：30；
期望获取SIB8的终端设备的数量：32；期望获取SIB9的终端设备的数量：15；
期望获取SIB10的终端设备的数量：8；期望获取SIB11的终端设备的数量：22；
期望获取SIB12的终端设备的数量：12；期望获取SIB13的终端设备的数量：8；
期望获取SIB14的终端设备的数量：7。
本申请实施例中，第三信息指示系统信息块当前的调度方式，例如，系统信息块当前的调度方式可以为确定第一信息之前，最后一次被调度时的调度方式。
一种实现方式中，AI设备可以向网络设备或网络设备的CU请求第三信息，AI设备一次可以请求获得多个系统信息块当前的调度方式；其中，网络设备的CU可以从网络设备的DU获取第三信息，并转发至AI设备。另一种实现方式中，网络设备或网络设备的CU可以周期性的向AI设备发送第三信息，每个周期可以获得多个系统信息块的第三信息，即获得多个系统信息块当前的调度方式。
如果系统信息块为基于广播的调度方式，那么第三信息还可以指示系统信息块的广播周期、频域资源以及广播该系统信息块的小区(cell)或片区(area)等信息。如前所述，AI设备可以获取多个系统信息块的第三信息，举例来说，多个系统信息块当前的调度方式可以如表1所示。
表1
Figure PCTCN2022108649-appb-000001
本申请实施例中，如果系统信息块的调度方式为基于需求的调度方式，那么还可以获取第四信息，第四信息可以指示以下至少一项：系统信息块被请求的次数；系统信息块对应的前导码数量；系统信息块被请求失败的次数。
其中，系统信息块被请求的次数，包括通过消息1请求系统信息块的次数和通过消息3请求系统信息块的次数，本申请实施例中，可以分别指示通过消息1请求系统信息块的次数，以及通过消息3请求系统信息块的次数，也可以指示一个总的被请求的次数。系统信息块被请求失败的次数，可以通过终端设备的随机接入信道(random access channel，RACH)报告确定，RACH报告中可以指示消息3冲突导致的接入失败。
一种实现方式中，AI设备可以向网络设备或网络设备的CU请求第四信息，其中，网络设备的CU可以从网络设备的DU获取第四信息，并转发至AI设备；AI设备每次可以请求多个系统信息块的第四信息。另一种实现方式中，网络设备或网络设备的CU可以周期性(例如以320ms为周期)的向AI设备发送第四信息，每个周期可以获得多个系统信息块的第四信息。
第四信息可以是周期性统计的信息，例如可以每隔一段时长统计一次系统信息块的被请求的次数等信息，获得该系统信息块的第四信息，每个周期可以获得多个系统信息块的第四信息。
S602：AI设备向网络设备发送第一信息。
其中，第一信息指示预测的系统信息块的调度方式，第一信息指示的调度方式可以为AI设备预测的在未来一段时长内的该系统信息块的调度方式。第一信息还可以指示第一信息的有效持续时长，从而提高系统信息块调度的灵活性。
另外，AI设备可以周期性的输出第一信息，可以满足不同时间段，终端设备对系统信息块的需求，减少时频资源的浪费。
一种可能的实现方式中，系统信息块的调度方式为基于需求的调度方式时，第一信息还可以指示系统信息块对应的前导码，前导码用于请求系统信息块。
在一种设计中，AI设备可以利用AI模型，推理第一信息，关于该AI模型可以参见图2中的介绍。AI设备可以将第二信息、第三信息以及第四信息中的至少一项输入到AI模型中，该AI模型对上述第二信息、第三信息以及第四信息中的至少一项进行AI推理，该AI模型的输出即为第一信息，该过程可以认为是进行了一次AI推理。
在另一种设计中，AI设备可以根据第二信息、第三信息以及第四信息中的至少一项，预测网络设备的流量负载、接入网络设备的终端设备通过随机接入方式请求系统信息块的成功率或期望获取系统信息块的终端设备的数量中的至少一项；AI设备可以根据预测的流量负载、成功率或终端设备的数量中的至少一项，确定第一信息。该过程可以认为是进行了两次AI推理，例如，AI设备可以将第二信息、第三信息以及第四信息中的至少一项，输入到一个AI模型中，该AI模型对上述第二信息、第三信息以及第四信息中的至少一项进行AI推理，输出流量负载、成功率或终端设备的数量中的至少一项。AI设备可以将上述预测的流量负载、成功率或终端设备的数量中的至少一项，输入到另一个AI模型中，该AI模型的输出即为第一信息。关于AI设备确定第一信息时，进行的AI推理的次数不作限定。另外，流量负载、成功率以及期望获取系统信息块的终端设备的数量，也可以通过其他方式确定，此处只是举例说明，并不限定只能通过第二信息、第三信息以及第四信息中的至少一项确定。
其中，一种实现方式中，流量负载可以根据第三信息确定，该流量负载可以是指预测的流量负载。例如，假设获取到N个系统信息块对应的N个第三信息，N为大于0的整数。N个系统信息块中，基于广播的调度方式的系统信息块的数量越多，需要消耗的广播资源就越大，流量负载就越高。例如，存在10个系统信息块基于广播的调度方式，那么流量负载可以认为大于或等于50％；存在2个系统信息块基于广播的调度方式，那么流量负载可以认为小于或等于15％。以上只是示例，流量负载还可以通过其他方式确定，例如流量负载还可以通过小区内终端设备的业务量、邻区内流入的终端设备的数量以及第三信息等确定。
一种实现方式中，成功率可以根据第四信息确定。例如，可以根据采用消息3请求系统信息块失败的次数与采用消息3请求系统信息块的次数确定成功率。
以上只是示例，还可能存在其他方式确定流量负载以及成功率，本申请对此并不限定。
本申请实施例中，AI设备预测第一信息的具体过程，可能存在多种实现方式，本申请实施例并不限定。
在一种设计中，若第二信息指示的数量大于或等于第一预设阈值，第三信息指示的调度方式为基于需求的调度方式，则第一信息指示的调度方式为基于广播的调度方式；
在一种设计中，若第二信息指示的数量小于第一预设阈值，第三信息指示的调度方式为基于广播的调度方式，则第一信息指示的调度方式为基于需求的调度方式。
在一种设计中，第三信息指示的调度方式为基于需求的调度方式，第四信息指示随机接入方式请求系统信息块的成功率小于或等于第二预设阈值，则第一信息指示的调度方式为基于广播的调度方式；
在一种设计中，第三信息指示的调度方式为基于需求的调度方式，第四信息指示随机接入方式请求系统信息块的成功率大于第二预设阈值，则第一信息指示的调度方式为基于需求的调度方式；
在一种设计中，第三信息指示的调度方式为基于广播的调度方式，网络设备的流量负载大于或等于第三预设阈值，则第一信息指示的调度方式为基于需求的调度方式；
在一种设计中，第三信息指示的调度方式为基于需求的调度方式，网络设备的流量负载小于第三预设阈值，则第一信息指示的调度方式为基于广播的调度方式。
S603：网络设备获取第一信息，并根据第一信息对系统信息块进行调度。
网络设备获取到第一信息之后，网络设备的CU可以将第一信息转发至相应的DU，网络设备的DU从而可以根据第一信息对系统信息块进行调度。
一种实现方式中，第一信息可以适用于网络设备的所有DU，即网络设备的所有DU可以按照第一信息指示的调度方式调度系统信息块；另一种实现方式中，第一信息可以适用于网络设备的部分DU，例如只适用于一个DU，即网络设备的部分DU按照第一信息指示的调度方式调度系统信息块。
另外，网络设备可以获取到多个系统信息块对应的第一信息，网络设备的DU可以按照每个系统信息块对应的第一信息对该系统信息块进行调度，具体调度过程不再赘述。
可选地，S604：网络设备向AI设备发送状态信息。状态信息是网络设备根据第一信息对系统信息块进行调度而获得的。
可选地，S605：AI设备向网络设备发送第五信息。其中，第五信息是基于状态信息确定的，第五信息用于对系统信息块的调度方式进行更新。
状态信息可以包括网络设备执行第一信息期间，系统运行的相关数据等信息，包括但不限于网络设备的资源利用率、终端设备通过随机接入方式接入网络的成功率等信息。
一种实现方式中，网络设备或网络设备的DU检测到终端设备通过随机接入方式接入网络的成功率较低，例如小于或等于第一阈值，网络设备则可以向AI设备指示终端设备通过随机接入方式接入网络的成功率小于或等于第一阈值。其中，第一阈值可以由AI设备推理得出，也可以是预设的阈值，例如50％。
可选地，状态信息还可以指示接入网络的成功率小于或等于第一阈值的原因，例如原因可以包括：用于随机接入的前导码数量较少，前导码系统信息块占用过多；通过消息3请求的系统信息块的数量较多，导致消息3竞争成功率下降。
AI设备根据状态信息确定终端设备接入网络的成功率较低时，可以将系统信息块的调度方式进行更新。假设网络设备的DU需要调度N个系统信息块，AI设备可以指示将N个系统信息块中全部或部分系统信息块的调度方式从基于需求的调度方式更新为基于广播调度方式。
一种可能的设计中，可以将N个系统信息块中的第一系统信息块的调度方式，从基于需求的调度方式更新为基于广播调度方式；其中，第一系统信息块为被请求的次数大于或等于第一预设次数的系统信息块。
一种可能的设计中，成功率小于或等于第一阈值的原因包括用于随机接入的前导码数量较少时，可以将N个系统信息块中，基于需求的调度方式，且通过消息1请求的系统信息块的调度方式更新为基于广播调度方式。
一种可能的设计中，成功率小于或等于第一阈值的原因包括通过消息3请求的系统信息块的数量较多时，可以将N个系统信息块中，基于需求的调度方式，且通过消息3请求的系统信息块的调度方式更新为基于广播调度方式。
一种实现方式中，网络设备可以通过状态信息向AI设备指示网络设备或网络设备的DU资源利用率大于或等于第二阈值，以及网络设备或网络设备的DU的预期资源利用率大于或等于第二阈值。其中，第二阈值可以由AI设备推理得出，也可以是预设的阈值，例如80％。
可选地，状态信息还可以指示在一定周期内系统信息块占用的资源百分比或资源个数，例如160毫秒(ms)内该系统信息块占用的资源百分比为5％，或，160ms内该系统信息块占用24资源块(resource block，RB)。
AI设备根据状态信息确定资源利用率大于或等于第二阈值，以及预期资源利用率大于或等于第二阈值时，可以将系统信息块的调度方式进行更新。假设网络设备的DU需要调度N个系统信息块，AI设备可以指示将N个系统信息块中全部或部分系统信息块的调度方式从基于需求的调度方式更新为基于广播调度方式。
一种可能的设计中，将N个系统信息块中的第二系统信息块的调度方式，从基于广播调度方式更新为基于需求的调度方式。
其中，期望获取第二系统信息块的终端设备的数量小于或等于第二预设数量。
一种可能的设计中，将N个系统信息块中，占用的资源百分比大于或等于预设百分比，或者占用的资源个数大于或等于预设个数的系统信息块，从基于广播调度方式更新为基于需求的调度方式。
一种实现方式中，网络设备确定系统信息块的调度方式与实际需求不匹配，例如系统 信息块实际被请求的次数较多，但是第一信息指示的调度方式为基于需求的调度方式。
网络设备可以通过状态信息向AI设备指示需要变更调度方式的系统信息块的编号，AI设备从而可以通过第五信息指示将需要变更调度方式的系统信息块的调度方式进行变更。例如，状态信息中包括的系统信息块的编号为：SIB2和SIB6。AI设备可以将SIB2和SIB6的调度方式变更。
通过上面的过程可知，期望获取系统信息块的终端设备的数量，结合终端设备的接入成功率等信息，利用AI模块推理出合理的调度方式，可以满足终端设备对系统信息块的需求，从而减少周期时频资源的浪费，以及降低终端设备通过请求方式请求系统信息块对其他终端设备随机接入造成的影响。
本申请实施例还提供一种方法，与图6所示的方法流程的区别在于，图6所示的方法流程中，AI设备独立于网络设备，位于网络设备之外，而在下面的方法流程中，AI设备布署在网络设备的DU内，或者DU具备AI设备相应的功能，如此由网络设备的DU推理系统信息块的调度方式。
如图7所示，为本申请实施例提供的一种通信方法流程示意图，该方法包括：
S701：网络设备的DU获取第二信息、第三信息以及第四信息中的至少一项。
第二信息、第三信息以及第四信息的具体含义，可以参考图6的流程中的描述，在此不再赘述。
其中，网络设备的DU可以通过TCE获取终端设备的MDT数据，从而获取第二信息。
网络设备的DU可以从网络设备的CU，获取网络设备的DU的小区中系统信息块的调度方式，即获取第三信息。网络设备的DU还可以从网络设备的CU，获取其他DU的小区中系统信息块的调度方式。
网络设备的DU可以自己确定本小区中系统信息块被请求的次数、系统信息块对应的前导码数量以及系统信息块被请求失败的次数等信息，即确定第四信息。
S702：网络设备的DU根据第二信息、第三信息以及第四信息中的至少一项确定第一信息。
在一种设计中，网络设备的DU可以利用AI模型，推理第一信息，关于该AI模型可以参见图2中的介绍。网络设备的DU中可以包括AI模块，该AI模块可以将第二信息、第三信息以及第四信息中的至少一项输入到AI模型中，该AI模型对上述第二信息、第三信息以及第四信息中的至少一项进行AI推理，该AI模型的输出即为第一信息，该过程可以认为是进行了一次AI推理。
在另一种设计中，网络设备的DU中的AI模块可以根据第二信息、第三信息以及第四信息中的至少一项，预测网络设备的流量负载、接入网络设备的终端设备通过随机接入方式请求系统信息块的成功率或期望获取系统信息块的终端设备的数量中的至少一项；AI模块可以根据预测的流量负载、成功率或终端设备的数量中的至少一项，确定第一信息。该过程可以认为是进行了两次AI推理。
本申请实施例中，网络设备的DU还可以向网络设备的CU发送第一信息。网络设备的CU在获取到多个DU的第一信息后，可以综合考虑多个DU之间的关系，从负载、资源利用以及终端设备接入成功率等方面考虑，可以更改部分或全部DU的第一信息。
在一种设计中，网络设备的CU可以利用AI模型，将多个DU的第一信息作为输入的信息，输出一个系统信息块配置信息，该系统信息块配置信息指示各个DU中的系统信息 块的调度方式，具体过程并不限定，在此不再赘述。
S703：网络设备的DU根据第一信息对系统信息块进行调度。
可选地，S704：网络设备的DU对系统信息块的调度方式进行更新。
网络设备的DU在对系统信息块进行调度时，可以根据终端设备的接入成功率、DU的资源利用率等信息，确定系统信息块的调度方式与实际需求不匹配时，对系统信息块的调度方式进行更新，具体过程可以参考前面的描述，在此不再赘述。
通过上述方案，在网络设备的DU中引入AI模块，网络设备的DU对本小区内的系统信息块的调度方式进行预测，并通过预测的调度方式调度系统信息块，可以获得较优的调度方式，提高系统资源利用率。
目前，控制资源集合0(control resource set zero，CORESET0)中除了可以承载SIB1的调度信息之外，CORESET0中还可以承载OSI中的系统信息块的调度信息，本申请实施例中，可以根据对系统信息块的需求信息，判断是否配置CORESET0，从而在不配置CORESET0时，将CORESET0对应的资源用于数据传输，从而提高资源利用率。
如图8所示，为本申请实施例提供的一种通信方法流程示意图，该流程中，以AI设备独立于网络设备为例进行描述，AI设备也可以位于网络设备的CU或DU中，还可以位于OAM设备，也可以独立作为一个模块位于网络设备或核心网侧。该方法包括：
S801：AI设备获取第一指示信息；
第一指示信息指示期望获取M个系统信息块的终端设备的数量，M个系统信息块对应的M个调度信息通过第一带宽单元承载，M为大于0的整数，一个调度信息用于调度一个系统信息块。
其中，AI设备可以通过TCE获取多个终端设备的MDT数据，从而根据多个终端设备的MDT数据确定第一指示信息。一种实现方式中，AI设备可以主动向TCE请求终端设备的MDT数据；另一种实现方式中，TCE可以周期性的向AI设备上报终端设备的MDT数据，本申请实施例对此并不限定。
其中，第一带宽单元可以为带宽部分(bandwidth part，BWP)或子载波等，本申请对此并不限定。AI设备还可以获取第一带宽单元的位置信息，例如第一带宽单元的起止RB编号，例如RBx至RBy，又例如第一带宽单元相对于BWP0的偏移，例如偏移x个RB等，BWP0为网络设备配置的初始BWP。
S802：AI设备向网络设备发送配置信息，配置信息指示在第一带宽单元中取消控制资源集合0。
在一种设计中，AI设备可以利用AI模型，推理配置信息，关于该AI模型可以参见图2中的介绍。AI设备可以将第一指示信息输入到AI模型中，该AI模型对上述第一指示信息进行AI推理，该AI模型的输出即为配置信息，该过程可以认为是进行了一次AI推理。
在一种设计中，AI设备可以在满足预设条件时，确定配置信息。举例来说，预设条件包括以下至少一项：期望获取M个系统信息块的终端设备的数量小于第三阈值；期望获取M个系统信息块的终端设备的数量与终端设备的总数量的比值小于第四阈值。第三阈值和第四阈值可以为AI设备通过AI模块推理获得的，也可以为预配置的值。其中，这里所涉及的终端设备，可以是指处于RRC连接态的终端设备。
例如，当仅有少量终端设备，例如通过第一带宽单元进行数据传输的所有终端设备中只有5％的终端设备，期望通过第一带宽单元获取这M个系统信息块，则可考虑不再第一 带宽单元上配置CORESET0。其中，这里所涉及的终端设备，可以是指处于RRC连接态的终端设备。
再例如，以第一带宽单元为BWP为例，通过BWP进行数据传输的所有终端设备中，期望通过该BWP获取这M个系统信息块的终端设备的数量小于第三阈值，则可考虑不再该终端设备的数量小于第三阈值上配置保留CORESET0。其中，如果一个终端设备通过该BWP进行数据传输，该BWP可以作为该终端设备的激活BWP，即终端设备在RRC连接态时激活的BWP。
本申请实施例中，配置信息还可以指示：通过RRC信令向终端设备发送系统信息块。其中，通过CORESET0调度的系统信息块都需要通过RRC信令发送，例如SIB1以及OSI中的系统信息块。
网络设备在获取到配置信息时，可以不在第一带宽单元中配置CORESET0，并可以通过CORESET0对应的资源进行数据传输。
通过上述方案，根据对第一带宽单元中系统信息块的需求信息，确定不配置第一带宽单元中的CORESET0时，将CORESET0对应的资源用于数据传输，从而可以提高资源利用率，提高下行容量。
