Description

信息收发方法与装置 技术领域
本申请实施例涉及通信技术领域。
背景技术
随着低频段频谱资源变得稀缺，毫米波频段能够提供更大带宽，成为了5G NR(New Radio，新无线)系统的重要频段。毫米波由于波长较短，具有与传统低频段不同的传播特性，例如更高的传播损耗，反射和衍射性能差等。因此通常会采用更大规模的天线阵列，以形成增益更大的赋形波束，克服传播损耗，确保系统覆盖。5G NR标准为波束管理设计了波束扫描，波束测量，波束汇报，波束指示等一系列的方案。但当收发波束数目比较大的时候，会大大增加系统的负荷和延时。
伴随着人工智能(Artificial Intelligence，AI)技术的发展，将人工智能技术应用到无线通信物理层上，来解决传统方法的难点成为当前一个技术方向。对于波束管理而言，利用AI模型，根据少量波束测量的结果预测出空间上最优的波束对，能够大幅度减少系统的负荷和延时。
应该注意，上面对技术背景的介绍只是为了方便对本申请的技术方案进行清楚、完整的说明，并方便本领域技术人员的理解而阐述的。不能仅仅因为这些方案在本申请的背景技术部分进行了阐述而认为上述技术方案为本领域技术人员所公知。
发明内容
假设通信系统的发送端有M个波束，接收端有N个波束，在现有的标准中，需要对M*N个波束进行测量，当M和N数量较大时，对M*N个波束进行测量会导致较大的系统负荷和较长的延时。利用模型(例如，AI模型)，通过少量的波束测量结果来预测最优的波束对，能够大大减少波束测量所导致的系统负荷和延时。
发明人发现，如果AI模型部署在终端设备侧，网络设备配置用于波束测量的参考信号，并通过不同的下行发送波束将参考信号发送给终端设备，用于波束测量，该测量结果作为AI模型的输入，但除了该测量结果外，AI模型还需要获取与该测量结果关联的参考信号和下行发送波束(对应关系)，由于参考信号是网络设备通过下行 发送波束发送给终端设备的，因此，网络设备已知该对应关系，然而现有技术(例如现有标准)中，终端设备还没有办法获知其测量使用的参考信号对应的下行发送波束信息(即无法获知该对应关系)。
针对上述问题的至少之一，本申请实施例提供一种信息收发方法以及装置。
根据本申请实施例的一个方面，提供一种信息收发装置，应用于终端设备，所述装置包括：
第一接收单元，其接收网络设备发送的参考信号的资源配置信息，所述资源配置信息包括或不包括用于指示与所述参考信号对应的下行发送波束的指示信息；
第二接收单元，其接收所述网络设备发送的参考信号。
根据本申请实施例的另一个方面，提供一种信息收发装置，应用于网络设备，所述装置包括：
第一发送单元，其向终端设备发送参考信号的资源配置信息，所述资源配置信息包括或不包括用于指示与所述参考信号对应的下行发送波束的指示信息；
第二发送单元，其向所述终端设备发送参考信号。
根据本申请实施例的另一个方面，提供一种通信系统，包括终端设备和/或网络设备，所述终端设备包括前述一个方面的信息收发装置，所述网络设备包括前述另一个方面的信息收发装置。
本申请实施例的有益效果之一在于：网络设备向终端设备发送的参考信号的资源配置信息中可以包括或不包括用于指示与所述参考信号对应的下行发送波束的指示信息，由此，终端设备能够根据该资源配置信息确定其测量使用的参考信号对应的下行发送波束(即测量使用的参考信号与下行发送波束的对应关系)，能够有效的使用AI模型来预测最优的波束对，能够大大减少波束测量所导致的系统负荷和延时。

以下通过示例对本申请实施例的场景进行说明，但本申请不限于此。
图1是本申请实施例的通信系统的示意图，示意性说明了以终端设备和网络设备为例的情况，如图1所示，通信系统100可以包括网络设备101和终端设备102、103。为简单起见，图1仅以两个终端设备和一个网络设备为例进行说明，但本申请实施例不限于此。
在本申请实施例中，网络设备101和终端设备102、103之间可以进行现有的业务或者未来可实施的业务发送。例如，这些业务可以包括但不限于：增强的移动宽带(eMBB，enhanced Mobile Broadband)、大规模机器类型通信(mMTC，massive Machine Type Communication)和高可靠低时延通信(URLLC，Ultra-Reliable and Low-Latency Communication)，等等。
其中，终端设备102可以向网络设备101发送数据，例如使用授权或免授权传输方式。网络设备101可以接收一个或多个终端设备102发送的数据，并向终端设备102反馈信息，例如确认ACK/非确认NACK信息等，终端设备102根据反馈信息可以确认结束传输过程、或者还可以再进行新的数据传输，或者可以进行数据重传。
值得注意的是，图1示出了两个终端设备102、103均处于网络设备101的覆盖范围内，但本申请不限于此。两个终端设备102、103可以均不在网络设备101的覆盖范围内，或者一个终端设备102在网络设备101的覆盖范围之内而另一个终端设备103在网络设备101的覆盖范围之外。
AI模型(或ML模型)包括但不限于：输入层(input)、多个卷积层、连接层(concat)、全连接层(FC)以及量化器等。其中，多个卷积层的处理结果在连接层进行合并，关于AI模型的具体结构可以参考现有技术，此处不再赘述。
图2是本申请各实施例的通信系统中发送波束和接收波束的一个示意图。如图2所示，在通信系统100中，以下行信道为例，网络设备101可以具有M1个下行发送波束DL TX，终端设备102可以具有N1个下行接收波束DL RX。
在本申请实施例中，如图2所示，用于预测波束测量结果的模型201可以被部署于网络设备101或终端设备102。模型201可以根据部分波束的测量结果，预测M1*N1个波束的测量结果。其中，模型201例如可以是AI模型。
此外，针对上行信道，网络设备101可以具有N2个上行接收波束(图2未示出)，终端设备102可以具有M2个上行发送波束UL TX(图2未示出)。
发明人发现，模型201部署在终端设备102中时，网络设备配置用于波束测量的参考信号，并通过不同的下行发送波束将参考信号发送给终端设备，用于波束测量，该测量结果作为AI模型的输入，但除了该测量结果外，AI模型还需要获取与该测量结果关联的参考信号对应的下行发送波束，由于AI模型部署在终端设备侧，终端设备不知道该参考信号对应的下行发送波束，由于参考信号是网络设备通过下行发送波束发送给终端设备的，因此，网络设备已知该下行发送波束(对应关系)，然而现有技术(例如现有标准)中，终端设备还没有办法获知其测量使用的参考信号对应的下行发送波束信息(即无法获知该对应关系)。
针对上述问题，本申请实施例提供一种信息收发方法以及装置，以下结合附图和实施例进行说明。
第一方面的实施例
本申请实施例提供一种信息收发方法，从终端设备侧进行说明。
图3是本申请实施例的信息收发方法的一示意图，如图3所示，该方法包括：
301，终端设备接收网络设备发送的参考信号的资源配置信息，所述资源配置信息包括或不包括用于指示与所述参考信号对应的下行发送波束的指示信息；
302，所述终端设备接收所述网络设备发送的参考信号。
值得注意的是，以上附图3仅对本申请实施例进行了示意性说明，但本申请不限于此。例如可以适当地调整各个操作之间的执行顺序，此外还可以增加其他的一些操作或者减少其中的某些操作。本领域的技术人员可以根据上述内容进行适当地变型，而不仅限于上述附图3的记载。
在一些实施例中，用于波束预测的AI模型部署在终端设备中，利用该AI模型，通过少量的波束对测量结果预测最优波束对，该AI模型输入参数为部分波束对的RSRP(Reference Signal Receiving Power，参考信号接收功率)值，也可以为部分波束对 的SINR(Signal to Interference plus Noise Ratio，信号与干扰加噪声比)值，输出参数的物理量为所有波束对的RSRP或者SINR，图4是本申请实施例中发送波束和接收波束以及AI模型示意图，如图4所示，例如下行发送波束有12个，下行接收波束有8个，总共有96波束对。通过配置，UE只测量了其中24个波束对RSRP(6个下行发送波束和4个下行接收波束)。此时AI模型的输入参数的维度为24，物理量为RSRP或SINR，输出参数的维度为96，物理量也为RSRP或SINR，可以从预测结果中选出最优的波束对。
为了使用该AI模型用于波束预测，部署在终端设备侧的AI模型需要获知测量参考信号的测量结果，以及与测量结果关联的下行发送波束，或者说测量使用的参考信号对应的下行发送波束，即终端设备需要获知参考信号和下行发送波束的对应关系。为此，在本申请实施例中，上述资源配置信息可以包括用于指示与所述参考信号对应的下行发送波束的指示信息。
通过上述实施例，网络设备向终端设备发送的参考信号的资源配置信息中可以包括或不包括用于指示与所述参考信号对应的下行发送波束的指示信息，由此，终端设备能够根据该资源配置信息确定其测量使用的参考信号对应的下行发送波束(即测量使用的参考信号与下行发送波束的对应关系)，能够有效的使用AI模型来预测最优的波束对，能够大大减少波束测量所导致的系统负荷和延时。
以下详细说明。
在一些实施例中，网络设备通过该资源配置信息为下行发送波束的测量配置测量资源(参考信号)，该测量资源(参考信号)可以是CSI-RS和/或SSB等参考信号，例如，该配置的测量资源是资源集列表，每个资源集由一个或者多个测量资源(参考信号)组成，换句话说，网络设备可以为终端设备配置一个或多个参考信号用于波束测量，该资源配置信息中包括测量资源集标识以及构成测量资源集的一个或者多个测量资源的标识，使用该测量资源标识来标识测量资源或使用测量资源集标识来标识测量资源集。
在一些实施例中，如前所述，现有的资源配置信息中包含了前述标识，本申请实施例中，在资源配置信息中新增指示与测量资源(参考信号)对应的下行发送波束的指示信息，由此，建立参考信号与下行发送波束的对应关系。以下详细说明，在以下的说明中，参考信号和测量资源或资源可以互相替换。
在一些实施例中，该指示信息可以以一个参考信号为粒度，指示与配置的每个参考信号对应的下行发送波束，或者可以以参考信号集(即多个参考信号)为粒度，指示与配置的参考信号集对应的下行发送波束，即该指示信息指示的下行发送波束为一个或多个，该指示信息指示的下行发送波束与一个参考信号对应或者与参考信号集中的多个参考信号对应。也就是说，所述指示信息指示的一个下行发送波束与所述一个参考信号对应；所述指示信息指示的多个下行发送波束分别与所述多个参考信号对应，与多个参考信号对应的多个下行发送波束相同或不同，本申请实施例并不以此作为限制。
例如，在参考信号为CSI-RS时，指示信息可以以一个参考信号为粒度，指示与配置的参考信号对应的下行发送波束，例如该资源配置信息(使用信息元NZP-CSI-RS-ResourceSet表示)中每个NZP-CSI-RS-ResourceId所对应的NZP-CSI-RS-Resource中新增指示信息，该指示信息可以使用信息元beamIndication表示，其用于指示与参考信号对应的下行发送波束TxBeam，或者说指示的下行发送波束TxBeam与该一个CSI-RS(通过NZP-CSI-RS-ResourceId指示的)对应，即在该资源配置信息中指示了配置的该一个参考信号和下行发送波束的对应关系，其中TxBeam字段为某个下行发送波束标识信息。以上字段名称还可以使用其他名称表示，本申请实施例并不以此作为限制。该NZP-CSI-RS-Resource使用抽象语法标记ASN.1数据格式可以表示为：
Figure PCTCN2022106851-appb-000001
也就是说，在NZP-CSI-RS-Resource中，新增指示与测量资源(参考信号)nzp-CSI-RS-ResourceId对应的下行发送波束的指示信息(beamIndication)，由此，确定了(参考信号)nzp-CSI-RS-ResourceId和指示的下行发送波束TxBeam的对应关系。
例如，在参考信号为CSI-RS时，指示信息可以以参考信号集(即多个参考信号)为粒度，指示与配置的多个参考信号对应的下行发送波束，例如在该资源配置信息(使用信息元NZP-CSI-RS-ResourceSet表示)中新增指示信息，该指示信息使用信息元beamIndicationlist表示，其用于指示与多个参考信号对应的多个下行发送波束TxBeam，或者说指示的多个下行发送波束TxBeam与该测量资源集列表中的多个测量资源(通过NZP-CSI-RS-ResourceId指示的)一一对应(按照指示顺序一一对应，但本申请实施例并不以此作为限制)，即在该资源配置信息中指示了配置的该参考信号集中的多个参考信号和多个下行发送波束的对应关系，其中TxBeam字段为某个下行发送波束标识信息。以上字段名称还可以使用其他名称表示，本申请实施例并不以此作为限制。该NZP-CSI-RS-ResourceSet使用抽象语法标记ASN.1数据格式可以表示为：
Figure PCTCN2022106851-appb-000002
也就是说，在NZP-CSI-RS-ResourceSet中，新增指示与测量资源(参考信号)对应的下行发送波束的指示信息(beamIndicationList)，指示多个下行发送波束。NZP-CSI-RS-ResourceSet中的多个CSI-RS和beamIndicationList中多个下行发送波束是按默认的顺序一一对应。beamIndicationList中指示的多个下行发送波束相同或不同。
例如，在参考信号为SSB时，指示信息可以以参考信号集(即多个参考信号)为粒度，指示与配置的多个参考信号对应的下行发送波束，例如在该资源配置信息(使用信息元CSI-SSB-ResourceSet表示)中新增指示信息，该指示信息使用信息元beamIndicationlist表示，用于指示与多个参考信号对应的多个下行发送波束TxBeam， 或者说指示的多个下行发送波束TxBeam与该测量资源集列表中的多个测量资源(通过SSB-Index指示的)一一对应(按照指示顺序一一对应，但本申请实施例并不以此作为限制)，即在该资源配置信息中指示了配置的该参考信号集中的多个参考信号和多个下行发送波束的对应关系，其中TxBeam字段为某个下行发送波束标识信息。以上字段名称还可以使用其他名称表示，本申请实施例并不以此作为限制。该CSI-SSB-ResourceSet使用抽象语法标记ASN.1数据格式可以表示为：
Figure PCTCN2022106851-appb-000003
也就是说，在CSI-SSB-ResourceSet中，新增指示与测量资源(参考信号)对应的下行发送波束的指示信息(beamIndicationList)，指示多个下行发送波束。CSI-SSB-ResourceSet中的多个SSB和beamIndicationList中多个下行发送波束是按默认的顺序一一对应。beamIndicationList中指示的多个下行发送波束相同或不同。
以上说明了一个资源配置信息中，指示信息的指示粒度，需要说明的是，网络设备可以为终端设备配置多个资源配置信息，每个资源配置信息中配置一个资源集列表，即网络设备为终端设备配置多个资源集列表，每个资源集由一个或者多个资源(参考信号)构成，下行发送波束的指示信息可以基于测量集中的一个测量资源或者测量资源集来进行，本实施例对此不做限制。例如网络设备可以以单个测量资源为粒度来配置下行发送波束的指示信息，可在NZP-CSI-RS-Resource中添加下行发送波束的指示信息，或以资源集为粒度来配置下行发送波束的指示信息，可在NZP-CSI-RS-ResourceSet和/或CSI-SSB-ResourceSet添加下行发送波束的指示信息。
以下以一个资源配置信息(例如一个NZP-CSI-RS-Resource或一个NZP-CSI-RS-ResourceSet或一个CSI-SSB-ResourceSet)中新增指示信息为例对该指 示信息的实施方式进行说明。
在一些实施例中，在所述资源配置信息包括所述指示信息时，隐式地指示使能与所述参考信号对应的下行发送波束的指示信息的配置，在所述资源配置信息不包括所述指示信息(指示信息缺省(省略))时，隐式地指示禁用与所述参考信号对应的下行发送波束的指示信息的配置。
例如，在用于波束预测的AI模型部署在终端设备，即终端设备需要使用AI模型进行波束预测时，网络设备发送的资源配置信息指示使能与所述参考信号对应的下行发送波束的指示信息的配置，即该资源配置信息包括上述指示信息，在用于波束预测的AI模型部署在网络设备，或者不需要使用AI模型预测最优波束时，网络设备发送的资源配置信息指示禁用与所述参考信号对应的下行发送波束的指示信息的配置，即该资源配置信息不包括上述指示信息(指示信息缺省(省略))，也就是该资源配置信息仍采用现有的方式实现。
在一些实施例中，该资源配置信息还可以包括使能禁用信息，所述使能禁用信息用于显式地指示使能或禁用与所述参考信号对应的下行发送波束的指示信息的配置。其中，在所述使能禁用信息指示使能与所述参考信号对应的下行发送波束的指示信息的配置时，所述资源配置信息包括所述指示信息，在所述使能禁用信息指示禁用与所述参考信号对应的下行发送波束的指示信息的配置时，所述资源配置信息不包括所述指示信息。例如，可以使用1比特信息元来表示该使能禁用信息，在该比特的值为1时，指示使能与所述参考信号对应的下行发送波束的指示信息的配置，在该比特的值为0时，指示禁用与所述参考信号对应的下行发送波束的指示信息的配置，反之亦可，或者，在资源配置信息中包含该1比特(该1比特的值为0或1均可)时，指示使能与所述参考信号对应的下行发送波束的指示信息的配置，在资源配置信息中不包含该1比特(使能禁用信息缺省(省略))时，指示禁用与所述参考信号对应的下行发送波束的指示信息的配置，反之亦可，此处不再一一举例。
例如，在用于波束预测的AI模型部署在终端设备，即终端设备需要使用AI模型进行波束预测时，网络设备发送的资源配置信息中包括1bit的使能禁用信息(且该比特值为1)，即该资源配置信息包括上述指示信息，在用于波束预测的AI模型部署在网络设备，或者不需要使用AI模型预测最优波束时，网络设备发送的资源配置信息中包括1bit的使能禁用信息(且该比特值为0)，即该资源配置信息不包括上述指示 信息(指示信息缺省(省略))，也就是该资源配置信息与现有不同之处在于，还包含了1比特的使能禁用信息。
例如，在用于波束预测的AI模型部署在终端设备，即终端设备需要使用AI模型进行波束预测时，网络设备发送的资源配置信息中包括1bit的使能禁用信息，即该资源配置信息包括上述指示信息，在用于波束预测的AI模型部署在网络设备，或者不需要使用AI模型预测最优波束时，网络设备发送的资源配置信息中不包括1bit的使能禁用信息，即该资源配置信息也不包括上述指示信息(指示信息缺省(省略))，也就是该资源配置信息仍采用现有的方式实现。
在一些实施例中，该使能禁用信息的指示粒度和下行发送波束的指示信息的指示粒度相同，即使能禁用信息可以以一个参考信号为粒度，或者可以以参考信号集(即多个参考信号)为粒度，指示使能或禁用与所述参考信号对应的下行发送波束的指示信息的配置。
例如，在以一个参考信号为粒度指示时，如前所述，该NZP-CSI-RS-Resource使用抽象语法标记ASN.1数据格式还可以表示为：
Figure PCTCN2022106851-appb-000004
也就是说，在NZP-CSI-RS-Resource中，新设计使能禁用信息，指示使能或禁用与一个参考信号对应的下行发送波束的指示信息的配置，如果被配置为使能enable(配置方式如前所述)，则资源配置信息还包括指示信息，如果被配置为禁用disable(配置方式如前所述)，则指示信息省略(缺省)。
例如，在以参考信号集(即多个参考信号)为粒度指示时，如前所述，该NZP-CSI-RS-ResourceSet使用抽象语法标记ASN.1数据格式还可以表示为：
Figure PCTCN2022106851-appb-000005
也就是说，在NZP-CSI-RS-ResourceSet中，新设计使能禁用信息，指示使能或禁用与多个参考信号(通过NZP-CSI-RS-ResourceId指示的)对应的下行发送波束的指示信息的配置，如果被配置为使能enable(配置方式如前所述)，则资源配置信息还包括指示信息，如果被配置为禁用disable(配置方式如前所述)，则指示信息省略(缺省)。
例如，在以参考信号集(即多个参考信号)为粒度指示时，如前所述，该CSI-SSB-ResourceSet使用抽象语法标记ASN.1数据格式还可以表示为：
Figure PCTCN2022106851-appb-000006
也就是说，在CSI-SSB-ResourceSet中，新设计使能禁用信息，指示使能或禁用 与多个参考信号(通过SSB-Index指示的)对应的下行发送波束的指示信息的配置，如果被配置为使能enable(配置方式如前所述)，则资源配置信息还包括指示信息，如果被配置为禁用disable(配置方式如前所述)，则指示信息省略(缺省)。
以上使能禁用信息，指示信息的名称仅为示例说明，本申请实施例并不以此作为限制。
在一些实施例中，上述指示信息指示的一个下行发送波束TxBeam或多个下行发送波束TxBeam可以是下行发送波束标识信息或下行发送波束角度信息或下行发送波束在训练集所有下行发送波束中的第一逻辑索引或下行发送波束所在波束对在训练集所有波束对中的第二逻辑索引来表示。需要说明的是，以上示例中，以TxBeam为下行发送波束标识信息为例，但该TxBeam还可以是下行发送波束角度信息或第一逻辑索引或第二逻辑索引。以下分别说明。
例如，下行发送波束指示信息是下行发送波束标识信息，包括水平方向波束序号第一标识和垂直方向波束序号第二标识，或者包括波束序号的第三标识。其中，如果下行发送波束是3D的波束赋形，即波束可以包含水平方向和垂直方向2个维度，则可以在水平和垂直方向分别进行顺序编号(以8个下行发送波束为例，如图5所示)，因此，下行发送波束标识信息包括水平方向波束序号第一标识和垂直方向波束序号第二标识。或者，也可以2个维度统一进行顺序编号(以8个下行发送波束为例，如图6所示)，因此，下行发送波束标识信息包括波束序号的第三标识，需要说明的是，图5和图6中以8个下行发送波束为例，先水平方向后垂直方向的顺序编号，但本申请实施例并不以此作为限制，也可以是先垂直方向再水平方向，或者是其他数量的下行发送波束，此处不再一一示例。上述第一标识、第二标识、第三标识可以使用预定比特的二进制编码表示。例如，在指示信息指示与参考信号集对应的多个下行发送波束时，该指示信息可以表示为多个下行发送波束标识信息#1,#3,#4.........，多个下行发送波束标识信息的排列顺序与参考信号集中的多个参考信号排列顺序一一对应。
例如，下行发送波束指示信息是下行发送波束角度信息，包括水平方向波束角度信息和垂直方向波束角度信息。其中，如果下行发送波束是3D的波束赋形，即波束可以包含水平方向和垂直方向2个维度，则可以使用下行发送波束在空间上的水平方向角度和垂直方向角度唯一指示，以8个下行发送波束为例，图7是下行发送波束角度信息示例图，如图6所示，假设垂直方向有2个角度(e.g.45度，135度)，水平 方向有4个角度(e.g-67度,-22度,22度,67度)，因此，下行发送波束角度信息包括水平方向波束角度信息和垂直方向波束角度信息，需要说明的是，图7中以8个下行发送波束，垂直方向2个角度，水平方向4个角度为例，但本申请实施例并不以此作为限制，此处不再一一示例。上述水平方向波束角度信息和垂直方向波束角度信息可以使用预定比特的二进制编码表示。例如，在指示信息指示与参考信号集对应的多个下行发送波束时，该指示信息可以表示为多个下行发送波束角度信息#(45，-67),#(45,22),#(45,67).........，多个下行发送波束角度信息的排列顺序与参考信号集中的多个参考信号排列顺序一一对应。
以上对于下行发送波束采用显式的方式指示，但本申请并不以此作为限制，还可以采用隐式的方式指示下行发送波束。
在一些实施例中，所述资源配置信息用于AI模型的训练和/或推理。
以上实施方式中，指示信息可以用于AI模型的训练阶段或推理阶段，本申请实施例并不以此作为限制。
在一些实施例中，在AI模型的训练阶段，需要收集训练数据来训练AI模型，终端设备需要测量所有的下行发送波束，并将测量结果作为AI模型训练的标签数据，AI模型需要知道测量结果使用的参考信号以及与该参考信号对应的下行发送波束，也就是说，网络设备需要通过该指示信息指示与该参考信号对应的所有下行发送波束，该指示信息的实施方式如前所述。
在一些实施例中，在AI模型的推理阶段，终端设备仅对部分下行发送波束进行测量，并利用测量结果输入至AI模型，推断最优发送波束，也就是说，网络设备只为部分下行发送波束发送参考信号，即通过该指示信息指示与参考信号对应的部分下行发送波束，该指示信息的实施方式如前所述。
此外，在AI模型的推理阶段，该指示信息还可以是下行发送波束在训练集所有下行发送波束中的第一逻辑索引或下行发送波束所在波束对在训练集所有波束对中的第二逻辑索引，其中，假设AI模型在训练阶段，已经收集了所有下行发送波束的信息，如图4所示，终端设备收集了所有96个波束对的测量结果，在推理阶段，该指示信息是第一逻辑索引或者第二逻辑索引。
在一些实施例中，可以在AI模型的训练阶段，对训练集中的所有波束进行统一编号(第二逻辑索引编号或第一逻辑索引编号)，在AI模型推理阶段，可以使用第一 逻辑索引或第二逻辑索引指示在推理阶段与参考信号对应的那些下行发送波束。
图8是本申请实施例中对下行接收波束和下行发送波束进行统一编号示意图，一共有96个波束对，第二逻辑索引为1～96，阴影部分为指示信息指示的与参考信号对应的下行发送波束所在波束对的第二逻辑索引1,7,50,56，该第二逻辑索引可以间接指示下行发送波束。
图9是本申请实施例中只对下行发送波束统一编号示意图，一共有12个下行发送波束，第一逻辑索引为1～12，阴影部分为指示信息指示的与参考信号对应的下行发送波束的第一逻辑索引1,2,7,8，该第一逻辑索引可以指示下行发送波束。
在一些实施例中，上述资源配置信息由下行控制信息(DCI)或无线资源控制信令RRC或媒体接入控制层控制元素MAC CE承载，例如该指示信息和/或使能禁用信息可以是RRC或MAC CE或DCI上承载的资源配置信息中新增的信息元。该资源配置信息中还可以包括其他信息元，例如指示使用参考信号的相关参数“Repetition”(重复)和跟踪相关参数“trs-Info”，资源映射配置等，具体可以参考现有技术，此处不再一一举例。
在一些实施例中，在301中配置了参考信号的资源配置信息后，在302中，网络设备基于该资源配置信息在下行信道发送该参考信号。也就是，终端设备根据资源配置信息中配置的参考信号映射的时频资源、周期等信息，在对应的时频资源上接收对应的参考信号。
图10是本申请实施例中信息收发方法示意图，如图10所示，该方法包括：
1001，终端设备接收网络设备发送的资源配置信息；
1002，终端设备接收网络设备发送的上报配置信息；
1003，终端设备接收网络设备发送的测量参考信号；
1004，终端设备使用该参考信号进行波束测量；
1005，终端设备将测量结果作为输入送入AI模型，得到预测结果；
