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，在对该AI模型进行训练的阶段，网络设备配置用于波束测量的参考信号集，并通过不同的发送波束分别将参考信号集中的参考信号发送给终端设备用来波束测量，并将测量结果作为AI模型训练的标签数据。在使用训练好的AI模型进行推理的阶段，AI模型只需要部分发送波束的测量 结果，即终端设备只需要接收参考信号集中的部分参考信号。不过由于AI模型部署在终端设备侧，终端设备知道AI模型需要的该部分参考信号的信息，但网络设备并不知道该部分参考信号的信息，目前并没有终端设备如何告知网络设备关于该部分参考信号的信息的方案。

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。

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，模型201可以部署在网络设备101中或终端设备102中。
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)。
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，该AI模型部署在该终端设备侧。
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，终端设备向网络设备发送获取第一参考信号集的请求指示信息；
302，所述终端设备接收所述网络设备发送的第一参考信号集中的第一参考信号。
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。
也就是说，在AI模型的推理阶段，并不需要所有发送波束的测量结果，只需要部分发送波束的测量结果，终端设备只需要接收该部分发送波束发送的参考信号(也称为部分参考信号或第一参考信号)进行波束测量，即可以得到预测结果。由于AI模型部署在终端设备侧，网络设备并不知道终端设备侧AI模型需要哪些部分参考信号。为此，在本申请实施例中，终端设备可以向网络设备发送获取第一参考信号集的请求指示信息。
通过上述实施例，终端设备向网络设备发送用于获取该部分参考信号的请求指示 信息，由此，告知网络设备在AI模型推理阶段使用的该部分参考信号的信息，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，网络设备通过第一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(参考信号集)，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多个参考信号用于波束测量，该第一资源配置信息中包括参考信号集标识(测量资源集标识)以及构成参考信号集(测量资源)集的一个或者多个测量资源(参考信号)的标识。
例如，在参考信号为CSI-RS时，该第一资源配置信息可以是非零功率CSI-RS资源集配置信息，NZP-CSI-RS-ResourceSet使用抽象语法标记ASN.1数据格式可以表示为：
Figure PCTCN2022110977-appb-000001
也就是说，nzp-CSI-ResourceSetId表示该参考信号集标识，SEQUENCE(SIZE(1..maxNrofNZP-CSI-RS-ResourcesPerSet))OF NZP-CSI-RS-ResourceId表示该参考信号集中的各个参考信号的标识。
例如，在参考信号为SSB时，该第一资源配置信息可以CSI-SSB-ResourceSet，其使用抽象语法标记ASN.1数据格式可以表示为：
Figure PCTCN2022110977-appb-000002
Figure PCTCN2022110977-appb-000003
也就是说，csi-SSB-ResourceSetId表示该参考信号集标识，SEQUENCE(SIZE(1..maxNrofCSI-SSB-ResourcePerSet))OF SSB-Index表示该参考信号集中的各个参考信号的标识。
在一些实施例中，该第一资源配置信息由RRC信令承载，其配置的参考信号集也可以理解为用于波束测量的参考信号的全集，AI模型的训练阶段需要该参考信号集中的所有参考信号进行波束测量的测量结果。
在一些实施例中，在301中，向网络设备发送用于获取第一参考信号集的请求指示信息，第一参考信号集中的第一参考信号是参考信号集中的一个或多个参考信号，该第一参考信号集也可以称为参考信号子集，终端设备可以根据AI模型的需求从参考信号集中选择一个或多个参考信号作为第一参考信号集，并向网络设备发送用于获取第一参考信号集的请求指示信息。
在一些实施例中，请求指示信息包括所述第一参考信号集中的第一参考信号的标识，或者所述请求指示信息通过比特位图或者起始位置和间隔信息的方式指示配置的参考信号集中的第一参考信号集。该请求指示信息可以由RRC或MAC CE或UCI承载。
以下分别说明。
例如，该请求指示信息包括所述第一参考信号集中的第一参考信号的标识，该第一参考信号的标识为CRI或SSB-RI，该所述请求指示信息还可以包括参考信号集标识，该参考信号集标识为nzp-CSI-RS-ResourceSetId或CSI-SSB-ResourceSetId，图5是该请求指示信息示例图，如图5所示，该请求指示信息包括参考信号集标识为nzp-CSI-RS-ResourceSetId或CSI-SSB-ResourceSetId，以及所述第一参考信号集中的K个第一参考信号的标识CRI/SSB-RI#1,CRI/SSB-RI#2，...,CRI/SSB-RI#K，该请 求指示信息以列表的形式给出每个第一参考信号的标识，在该实施例中，该请求指示信息可以是新增的RRC信令或者是现有RRC信令或UCI中新增的信息元，本申请实施例并不以此作为限制。
例如，该请求指示信息通过比特位图的方式指示配置的参考信号集中的第一参考信号集，该比特位图中比特的数量可以根据参考信号集中参考信号的数量确定，每一个比特对应参考信号集中的一个参考信号，该比特的值用于指示对应的参考信号是否是第一参考信号(或者说用于指示第一参考信号集中是否包含该比特对应的参考信号)，例如，比特值为0时，指示该参考信号不是第一参考信号，不被包含在第一参考信号集中，比特值为1时，指示该参考信号是第一参考信号，被包含在第一参考信号集中，反之亦可；该所述请求指示信息还可以包括参考信号集标识，该参考信号集标识为nzp-CSI-RS-ResourceSetId或CSI-SSB-ResourceSetId。图6是该请求指示信息示例图，如图6所示，该请求指示信息包括参考信号集标识(ID)为nzp-CSI-RS-ResourceSetId或CSI-SSB-ResourceSetId，该参考信号集标识对应的参考信号集中有N个参考信号，该请求指示信息还包括N个比特，N个比特分别依次对应参考信号集中的参考信号#0，参考信号#1...，参考信号#N，例如N＝8，该比特位图为10000110，则参考信号集中的参考信号#0，#5，#6为第一参考信号，被包含在第一参考信号集中，或者说比特位图为10000110指示第一参考信号集中的第一参考信号包括参考信号集中的参考信号#0，#5，#6，在该实施例中，该请求指示信息可以是新增的RRC信令或者是现有RRC信令或UCI中新增的信息元，本申请实施例并不以此作为限制；例如，该请求指示信息还可以是新增的MAC CE信令，该所述请求指示信息还可以包括小区标识(Cell ID)和/或部分带宽BWP标识(BWP ID)等。图7是该请求指示信息示例图，如图7所示，该请求指示信息中包含小区标识、BWP标识、参考信号集标识(例如6比特)、以及指示参考信号集中的每个参考信号的是否为第一参考信号的比特T(k)；如果T(k)值为0的话，表示T(k)所对应的参考信号不是第一参考信号，为1的话，表示其所对应的参考信号为第一参考信号，所有第一参考信号构成第一参考信号集。例如参考信号集中参考信号个数为64，N值为10，k的值为0～63。

在一些实施例中，在该第二资源配置信息是新增的信令时，该第二资源配置信息也可以通过MAC CE信令实现，例如，在RRC信令配置了第一资源配置信息后，采用MAC CE来激活/去激活参考信号集中的参考信号，以间接指示第一参考信号集中的各个第一参考信号的资源配置。关于该MAC CE信令激活/去激活参考信号集中的参考信号的方法可以是比特位图或者起始位置和间隔信息的方式指示，例如，采用比特位图或者起始位置和间隔信息的方式指示参考信号集中各个参考信号是激活还是去激活，即采用比特位图或者起始位置和间隔信息的方式指示参考信号集中的激活参考信号，将激活参考信号作为第一参考信号集中的第一参考信号，具体与请求指示信息MAC CE信令实现方式类似，此处不再一一赘述。
需要说明的是，以上各字段名称仅为示例，本申请实施例并不以此作为限制。
在一些实施例中，该请求指示信息在第一资源配置信息(不包含第二资源配置信息)之后但在第二资源配置信息之前发送。
