本公开涉及无线通信技术领域,尤其涉及一种下行波束预测方法、设备、装置及存储介质。
在新无线(New Radio,NR)下行波束管理场景中,确定最优下行波束的方式,需要基站循环在不同方向发送Tx beam(发送波束),终端(User Equipment,UE)使用Rx beam(接收波束)接收Tx beam,并测量所有Tx beam上发送的信道状况信息参考信号(Channel State Information Reference Signal,CSI-RS)或同步信号块(Synchronization Signal Block,SSB)信号,选出接收性能(如参考信号接收功率(Reference Signal Received Power,RSRP))最好的波束(best beam),用于后续基站使用该下行波束给终端传输信息。
相关技术的实现方案,CSI-RS或SSB信号需要在所有Tx beam上发送,资源消耗较大。并且,终端需要分别测量所有Tx beam上发送的CSI-RS或SSB信号,因此终端实现较为复杂,并且测量开销较大。

为了便于更加清晰地理解本公开各实施例的技术方案,首先对本公开各实施例相关的一些技术内容进行介绍。
1、三种计算下行(Downlink,DL)最优波束(best beam)的方式。
一种是测量所有下行波束对(DL beam pair)(基站的一个Tx beam和UE的一个Rx beam组成的一个beam pair)的RSRP,得到最大的RSRP对应的beam pair即为最优beam pair,并告知基站,后续基站采用该beam pair中的Tx beam给UE发送信息,UE采用该beam pair中的Rx beam接收信息。
另一种是UE固定或选择一个最好的DL Rx beam,接收测量基站发送的所有DL Tx beam的接收功率RSRP,得到最大的RSRP对应的Tx beam即为最优Tx beam,并告知基站,后续基站采用该Tx beam给UE发送信息。
再一种是基站固定或选择一个最好的DL Tx beam,UE采用所有DL Rx beam接收测量基站发送的该DL Tx beam的接收功率RSRP,得到最大的RSRP对应的Rx beam即为最优Rx beam,后续基站采用该Tx beam给UE发送信息时,UE采用该最优Rx beam接收。
如上所述,对于DL beam pair测量方式,UE需要使用全部的Rx beam接收基站发送的每个Tx beam的CSI-RS/SSB进行测量。例如,UE有4个Rx beam,基站有32个Tx beam,如果UE采用全部Rx beam分别接收每个Tx beam,则需要测量4*32=128个CSI-RS/SSB,即每个Rx beam都需要测量所有的Tx
beam,才能计算出,最好的beam pair。对于DL Tx beam测量方式,UE固定或选择一个最好的Rx beam,测量基站发送的所有Tx beam,需要测量32个Tx beam,才能计算出,最好的Tx beam。对于DL Rx beam测量方式,也存在同样的问题。
考虑到上述计算方式需要测量全部的Rx beam和Tx beam,用于测量的参考信号占用传输资源较大,UE测量复杂度高,测量消耗较大,UE测量时延较高。本公开提出利用人工智能(Artificial Intelligence,AI)或机器学习(Machine Learning,AI)技术对下行波束进行预测,对于DL beam pair测量方式,只需要测量一部分DL beam pair,例如只发送32个Tx beam中的8个,则UE只需要测量4*8=32个beam pair上的CSI-RS/SSB,就可以准确预测出32个Tx beam和4个Rx beam组成的128个beam pair中接收性能最好的beam pair;对于DL Tx beam测量方式,UE固定或选择一个最好的Rx beam,只需要测量8个Tx beam,就可以准确预测出32个Tx beam中接收性能最好的Tx beam。当然本公开还可以用于其他场景,例如测量其他便于测量的发送SSB的宽beam,或其他频段的beam,从而预测发送CSI-RS的窄beam,或者预测高频率的beam中的best beam;又例如利用以前测量过的beam测量结果,预测出基站未来发送的Tx beam或beam pair中接收性能最好的beam(pair);又例如,DL Rx beam预测,基站固定或选择一个最好的Tx beam,连续发送参考信号(Reference Signal,RS),UE使用不同的DL Rx beam接收测量RS,通过测量结果,预测出最好的Rx beam。从而可以节省RS发送资源、UE测量开销和降低UE测量时延。
图1为本公开实施例提供的下行波束预测方法的流程示意图之一,如图1所示,该方法应用于第一通信设备,包括:
步骤100、接收第一信息,第一信息包括数据集、参考信号RS配置、波束描述信息中的一种或多种。
步骤101、基于第一信息,对用于下行波束预测的人工智能或机器学习AI/ML模型进行训练或更新。
步骤102、基于训练或更新后的AI/ML模型,预测出一个或多个目标下
行波束,目标下行波束用于第一通信设备与第二通信设备之间的信息传输。
具体地,第一通信设备可以是终端或网络设备(例如基站),相应地,第二通信设备可以是与第一通信设备之间进行信息传输的网络设备或终端。
例如,在第一通信设备为终端的情况下,第二通信设备可以为网络设备。终端可以接收第一信息(网络设备或第三方设备发送的),根据接收到的第一信息,终端可以对用于下行波束预测的AI/ML模型进行训练或更新,从而预测出一个或多个目标下行波束,预测出的目标下行波束用于终端和网络设备之间的信息传输。
在第一通信设备为网络设备的情况下,第二通信设备可以为终端。网络设备可以接收第一信息(终端或第三方设备发送的),根据接收到的第一信息,网络设备可以对用于下行波束预测的AI/ML模型进行训练或更新,从而预测出一个或多个目标下行波束,预测出的目标下行波束用于终端和网络设备之间的信息传输。
为了避免终端预测出的目标下行波束无法被网络设备识别,或者网络设备预测出的目标下行波束无法被终端识别的问题,本公开实施例中,第二通信设备可以向第一通信设备发送第一信息,第一信息可以包括数据集、参考信号RS配置、波束描述信息中的一种或多种。第一通信设备接收到第一信息后,可以根据第一信息对用于下行波束预测的AI/ML模型进行训练或更新。其中,对模型进行更新包括对模型进行微调(Fine-tuning),即第一通信设备接收到第一信息后,可以根据第一信息对用于下行波束预测的AI/ML模型进行微调。该用于下行波束预测的AI/ML模型的功能可以包括:空域预测,频域预测,时域预测,下行beam pair预测,下行Tx beam预测,下行Rx beam预测等等。空域预测是指测量少量的波束,或者其他参考信号类型的波束,预测大量波束中的最优波束;频域预测是指测量频率1上的波束,预测另一个频率2上的波束中的最优波束;时域预测是指测量现在时刻的波束,预测未来时刻的最优波束。
其中,RS测量结果可以是RSRP等任意可以表示下行波束接收性能的测量结果,具体形式不做限定。
得到训练或更新后的模型后,第一通信设备可以根据RS测量结果,通过训练或更新后的模型预测出一个或多个目标下行波束,预测出的目标下行波束可以是Tx beam,或者Rx beam,或者beam pair,其用于第一通信设备和第二通信设备之间的信息传输。
第一通信设备接收到的第一信息可以是由第二通信设备或者第三方设备预先定义的。
其中,在第三方设备预先定义第一信息的情况下,一种实施方式中,第三方设备可以将第一信息发送给第一通信设备和第二通信设备;或者,第三方设备可以将第一信息发送给第二通信设备,第二通信设备接收第一信息后,再发送给第一通信设备。
第一信息可以是通过Uu接口的控制信道或者数据信道传送的,也可以通过其他接口、其他信道来传送,具体情形不做限制。
本公开实施例提供的下行波束预测方法,通过向第一通信设备发送数据集、RS配置、波束描述信息中的一种或多种,第一通信设备可以基于这些信息来对用于下行波束预测的AI/ML模型进行训练或更新,并基于训练或更新后的AI/ML模型预测出一个或多个目标下行波束,从而可以有效节省RS发送资源、UE测量开销和降低UE测量时延。
可选地,接收第一信息,包括:
接收第二通信设备发送的第一信息。
具体地,当第一通信设备为终端时,终端接收到的第一信息可以是由网络设备发送给终端的。一种可能的实现方式中,网络设备预先定义并将第一信息发送至终端。例如,网络设备预先定义一个RS配置,并将RS配置发送至终端,终端根据网络设备发送的RS配置来对用于下行波束预测的AI/ML模型进行训练或更新。
当第一通信设备为网络设备时,网络设备接收到的第一信息可以是终端发送的。一种可能的实现方式中,终端发送的第一信息可以包括数据集和/或波束描述信息,不包括RS配置。终端预先定义第一信息并将第一信息发送至网络设备。例如,终端预先定义一个数据集,并将数据集发送至网络设备,
网络设备根据终端发送的数据集来对用于下行波束预测的AI/ML模型进行训练或更新。
可选地,数据集中包含以下一项或多项:
数据集标识;
一个或多个数据集样本,数据集样本中包括多个波束标识、每个波束标识对应波束的RS测量结果以及一个或多个作为预测标签的波束标识。
具体地,数据集可以是一个或多个,数据集标识代表了不同的数据集,不同的数据集对应的数据集标识不同。
数据集样本中包括了多个波束标识(beam ID),这些beam ID对应的波束的RS测量结果,以及一个或多个作为预测标签的beam ID。可以理解的是,终端或网络设备或第三方设备预先定义数据集的过程中,将每个下行波束对应一个beam ID。一个下行波束可以是一个Tx beam,或者一个Rx beam,或者一个beam pair。
在对用于下行波束预测的AI/ML模型进行训练或更新的过程中,第一通信设备可以将数据集样本中的多个beam ID对应的下行波束的RS测量结果作为模型的输入;将数据集样本中的一个或多个作为预测标签的beam ID作为模型的输出标签。
可选地,RS配置中包含以下一项或多项:
RS配置标识;
属于测量集合的第一RS配置;
属于预测集合的第二RS配置;
测量集合图样,测量集合图样用于指示属于测量集合的第一RS配置;
其中,第一RS配置用于获取RS测量结果作为模型输入;第二RS配置用于确定一个或多个下行波束作为预测标签。
具体地,RS配置可以是一个或多个,RS配置标识代表了不同的RS配置,不同的RS配置对应的RS配置标识不同。RS配置可以包括RS的种类(例如CSI-RS、SSB、相位跟踪参考信号(Phase-tracking Reference Signal,PT-RS)、小区参考信号(Cell Reference Signal,CRS)、解调参考信号(Demodulation
Reference Signal,DMRS)等)、RS发送资源和RS标识(RS ID)等。其中,RS ID为RS指示符(RS Indication),例如,CSI-RS的指示符为CRI,SSB的指示符为SSBRI。
测量集合指的是集合中的RS配置或者波束,用于获取RS测量结果作为模型的输入;预测集合指的是集合中的RS配置或者波束,用于确定一个或多个下行波束作为预测标签。
例如,第一通信设备测量该测量集合中beam上发送的RS,得到RS的测量结果,并将RS测量结果作为模型的输入;第一通信设备通过测量该预测集合中beam上发送的RS,用非AI/ML的方法计算出一个或多个best beam,并将这一个或多个best beam作为模型的输出标签。
由于第一通信设备接收属于测量集合的第一RS配置和属于预测集合的第二RS配置之后的行为有区别,因此,需要区分不同的RS配置分别属于哪个集合。
一种实施方式中,可以用RS配置的标识ID区分,例如ID=0是测量集合的配置,ID=1是预测集合的配置;或者ID是奇数代表测量集合的配置,ID是偶数代表预测集合的配置。
在测量集合为预测集合子集的情况下,可以只对预测集合进行RS配置,RS配置中可以包括属于预测集合的第二RS配置和测量集合图样,通过测量集合图样来指示预测集合中属于测量集合的第一RS配置。
可选地,测量集合图样包括以下一种或多种:
(1)第一图样,第一图样用于指示属于预测集合的每个第二RS配置是否属于测量集合。
具体地,可以通过第一图样指示属于预测集合的每个第二RS配置是否属于测量集合,进而指示预测集合中属于测量集合的第一RS配置。
一种实施方式中,第一图样可以是在每个RS资源配置中增加1比特,例如当该比特=1时,表示该RS既属于预测集合,也属于测量集合;当该比特=0时,表示该RS只属于预测集合。
一种实施方式中,第一图样可以是与RS资源配置个数相等的字符串或
位图(bitmap),例如,当对应位置的比特=1时,表示该RS既属于预测集合,也属于测量集合;当对应位置的比特=0时,表示该RS只属于预测集合,那么01011可以表示预测集合中的第2、4、5个RS为测量集合。
(2)第二图样,第二图样用于指示属于测量集合的RS配置所对应的RS标识。
具体地,可以通过第二图样指示属于测量集合的RS配置所对应的RS标识,进而指示预测集合中属于测量集合的第一RS配置。
例如,第二图样为:{2,4,6,8},可以表示预测集合中的第2、4、6、8个RS为测量集合。
(3)第三图样,第三图样用于指示属于测量集合的RS配置所满足的RS序号排列规律。
具体地,可以通过第三图样指示属于测量集合的RS配置所满足的RS序号排列规律,进而指示预测集合中属于测量集合的第一RS配置。
例如,可以配置第三图样为:预测集合中的偶数序号的RS为测量集合。可以用字符串表示不同的规律,例如2比特可以表示4种规律。
(4)第四图样,第四图样用于指示属于测量集合的RS配置所对应的波束标识。
具体地,在预测集合中为每个RS配置对应的beam ID的情况下,可以通过第四图样指示属于测量集合的RS配置所满足的波束序号,进而指示预测集合中属于测量集合的第一RS配置。
例如,第四图样为:{2,4,6,8},可以表示预测集合中的第2、4、6、8个下行波束为测量集合。
(5)第五图样,第五图样用于指示属于测量集合的RS配置所满足的波束序号排列规律。
具体地,在预测集合中为每个RS配置对应的beam ID的情况下,可以通过第五图样指示属于测量集合的RS配置所满足的波束序号排列规律,进而指示预测集合中属于测量集合的第一RS配置。
例如,配置第五图样为:预测集合中的偶数序号的下行波束为测量集合。
可以用字符串表示不同的规律,例如2比特可以表示4种规律。
对于测量集合为预测集合的子集的情况,在RS配置时可以采用测量集合图样指示的方式,从而节省用于配置的比特开销。
可选地,波束描述信息中包含以下一项或多项:
波束标识;
RS标识;
网络设备的天线配置信息;
波束的角度信息;
波束的宽度信息。
具体地,第一通信设备还可以基于波束描述信息对用于下行波束预测的AI/ML模型进行训练或更新,波束描述信息中可以包含beam ID、RS ID、网络设备的天线配置信息、波束的角度信息、波束的宽度信息中的一项或多项。可选地,波束描述信息可以作为辅助信息与数据集和/或RS配置一起使用,对用于下行波束预测的AI/ML模型进行训练或更新,以及后续预测流程。
一个波束描述信息中包括一个或多个下行波束的描述信息。一个下行波束可以是一个Tx beam,或者一个Rx beam,或者一个beam pair。可选地,在一个波束描述信息中包括多个下行波束的描述信息时,可以按照列表的方式,分别对多个下行波束进行描述。
可以理解的是,终端或网络设备或第三方设备预先定义波束描述信息的过程中,将每个下行波束对应一个beam ID。RS ID为在该下行波束上发送的RS的指示符,例如,CSI-RS的指示符为CRI,SSB的指示符为SSBRI。对一个下行波束进行描述时,还可以用该下行波束的网络设备的天线配置信息,该下行波束的角度信息和该下行波束的宽度信息来对该下行波束进行描述。
可选地,预测出一个或多个目标下行波束之后,该方法还包括:
向第二通信设备发送第二信息。
具体地,在第一通信设备预测出一个或多个目标下行波束后,第一通信设备可以向第二通信设备发送第二信息,第二信息用于将第一通信设备预测出的一个或多个目标下行波束的结果告知第二通信设备。
第二通信设备接收到第一通信设备发送的第二信息后,可以根据第一信息和第二信息得知第一通信设备预测出的一个或多个目标下行波束,进而第一通信设备和第二通信设备之间可以在目标下行波束(即best beam)上传输信息,提升系统的传输性能。
其中,第二信息中包含以下一项或多项:
(1)目标下行波束对应的波束标识。
第二信息中可以包括目标下行波束对应的beam ID,从而第二通信设备可以根据目标下行波束对应的beam ID得知第一通信设备通过AI/ML模型推测出的目标下行波束。
因为第一信息是第二通信设备定义的或者是第三方设备定义但第二通信设备已知的,所以beam ID和物理波束的映射关系是第二通信设备已知的,即第一通信设备使用第一信息训练或更新的AI/ML模型的预测出的一个或多个目标下行波束对应的beam ID,可以被第二通信设备识别,并对应到物理实际的目标下行波束,从而第一通信设备和第二通信设备之间后续可以用该目标下行波束进行通信。
一种实施方式中,第一通信设备通过AI/ML模型只推测出一个目标下行波束,第一通信设备可以将该目标下行波束对应的beam ID发送给第二通信设备。
一种实施方式中,第一通信设备通过AI/ML模型推测出多个目标下行波束,第一通信设备可以选择其中一个目标下行波束对应的beam ID将其发送给第二通信设备;或者,第一通信设备可以将多个目标下行波束对应的beam ID发送给第二通信设备,由第二通信设备选择其中一个。
(2)目标下行波束对应的RS标识。

具体地,网络设备可以确定RS配置,并发送给终端。网络设备确定第一信息可以是网络设备自己预先定义的或者由第三方设备预先定义并发送给网络设备的。
终端接收到网络设备发送的RS配置后,可以根据RS配置对用于下行波
束预测的AI/ML模型进行训练或更新。其中,对模型进行更新包括对模型进行微调,即终端接收到RS配置后,可以根据RS配置对用于下行波束预测的AI/ML模型进行微调。该用于下行波束预测的AI/ML模型的功能可以包括:空域预测,频域预测,时域预测,下行beam pair预测,下行Tx beam预测,下行Rx beam预测等等。空域预测是指测量少量的波束,或者其他参考信号类型的波束,预测大量波束中的最优波束;频域预测是指测量频率1上的波束,预测另一个频率2上的波束中的最优波束;时域预测是指测量现在时刻的波束,预测未来时刻的最优波束。

由于终端接收属于测量集合的第一RS配置和属于预测集合的第二RS配置之后的行为有区别,因此,需要区分不同的RS配置分别属于哪个集合。
一种实施方式中,可以用RS配置的标识ID区分,例如ID=0是测量集合的配置,ID=1是预测集合的配置;或者ID是奇数代表测量集合的配置,ID是偶数代表预测集合的配置。

具体地,可以通过第一图样指示属于预测集合的每个第二RS配置是否属于测量集合,进而指示预测集合中属于测量集合的第一RS配置。
一种实施方式中,第一图样可以是在每个RS资源配置中增加1比特,例如当该比特=1时,表示该RS既属于预测集合,也属于测量集合;当该比特=0时,表示该RS只属于预测集合。
一种实施方式中,第一图样可以是与RS资源配置个数相等的字符串或位图,例如,当对应位置的比特=1时,表示该RS既属于预测集合,也属于测量集合;当对应位置的比特=0时,表示该RS只属于预测集合,那么01011可以表示预测集合中的第2、4、5个RS为测量集合。

(4)第四图样,第四图样用于指示属于测量集合的RS配置所对应的波束标识。
具体地,在预测集合中为每个RS配置对应的beam ID的情况下,可以通过第四图样指示属于测量集合的RS配置所满足的波束序号,进而指示预测集合中属于测量集合的第一RS配置。

本公开各实施例提供的方法是基于同一申请构思的,因此各方法的实施可以相互参见,重复之处不再赘述。
以下通过具体应用场景的实施例对本公开各上述实施例提供的方法进行举例说明。
实施例一:UE基于数据集进行AI/ML模型的训练或更新。
步骤1:UE接收一个或多个数据集。
该一个或多个数据集,可以来自于基站或第三方设备。
数据集包括:数据集标识,一个或多个数据集样本。
数据集样本包括:多个beam ID,以及该beam ID对应的beam的RSRP(作为AI/ML模型(model)的训练、更新或Fine-tuning的输入),一个或多个最优的beam ID(作为AI/ML模型的训练、更新或Fine-tuning的输出标签)。
不同的beam ID实际上对应不同的物理beam(即实际发送的beam)。
这里的beam可以是beam pair,或者Tx beam,或者Rx beam。
步骤2:UE基于数据集进行AI/ML模型的训练、更新或Fine-tuning,得到对应的AI/ML模型。
如果UE用不同的数据集训练、更新或Fine-tuning,可以得到不同的AI/ML模型。不同的数据集,可以针对不同的应用场景,或者基站配置,或者AI功能。
其中,应用场景包括:城市,农村,室内,室外,高速公路,高铁,Uma,Umi等等;基站配置包括:基站天线配置,波束配置,参考信号配置等等;AI功能,主要包括空域预测、频域预测、时域预测、下行beam pair预测、下行Tx beam预测、下行Rx beam预测等等。其中,空域预测是指测量少量的beam,或者其他参考信号类型的beam,预测大量beam中的best beam;频域预测是指测量频率1上的beam,预测另一个频率2上的beam中的best beam;时域预测是指测量现在时刻的beam,预测未来时刻的best beam。
步骤3:UE对测量集合中的Tx beam上发送的RS进行测量,使用AI/ML模型进行最优波束预测,推理得到一个或多个最优beam ID。
如果是beam pair预测,UE使用不同的Rx beam对基站发送的每个Tx beam上的RS(例如,CSI-RS或者SSB)测量,得到每个Tx beam和Rx beam pair对应的RSRP;如果是Tx beam预测,UE使用一个Rx beam对基站发送的每个Tx beam上的RS(例如,CSI-RS或者SSB)测量,得到每个Tx beam对应的RSRP;如果是Rx beam预测,UE使用不同的Rx beam对基站发送的一个Tx beam上的RS(例如,CSI-RS或者SSB)测量,得到每个Rx beam对应的RSRP。

步骤4:UE将该一个或多个最优beam ID上报给基站。
如果推理得到一个最优beam ID,则将该beam ID上报给基站;如果推理
得到多个最优beam ID,则选择一个beam ID上报给基站,或者都上报给基站,由基站选择一个。
如果UE用不同的数据集训练、更新或Fine-tuning得到多个AI/ML模型,UE还需要将数据集对应的model ID上报给基站,即UE不仅需要上报给基站预测得到的最优beam ID,也需要上报预测该beam的model的ID。
如果数据集和训练、更新或Fine-tuning的model是一一对应的,那么终端也可以上报数据集标识信息,代表上述model ID。

步骤5:基站根据beam ID和物理beam的映射关系,得到物理实际的最优beam,从而基站用该beam和UE进行通信。
因为数据集是基站定义的或者是第三方定义,但基站已知的(第三方需要告知基站该数据集中的beam ID和物理实际beam的对应关系),所以基站根据beam ID和物理beam的映射关系,得到物理实际的最优beam,从而基站用该beam和UE进行通信。
如果UE用不同的数据集训练、更新或Fine-tuning得到多个AI/ML模型,基站根据UE上报的model ID,或数据集标识信息,或{输入Tx beam数,输出Tx beam数}对信息,得到UE使用该数据集或{输入Tx beam数,输出Tx beam数}对训练、更新或Fine-tuning得到的model输出的beam ID和物理beam的映射关系,从而得到物理实际的最优beam,基站用该beam和UE进行通信。

特别的,对于UE测量一部分beam,预测全部beam的场景,即测量集合是预测集合的子集,在RS配置时,可以有如下优化方法:
只配置预测集合的RS,并且配置测量集合的图样(pattern),这样UE就可以基于预测集合和图样,得到测量集合的RS配置(即预测集合RS配置的子集),从而节省用于配置的比特开销。
配置测量集合的图样的方法:

其中,RS ID是指beam pair预测的最优beam pair中的Tx beam上配置的RS ID,或Tx beam预测的最优Tx beam上配置的RS ID,或Rx beam预测的最优Rx beam的RS ID。
推理得到一个或多个最优beam,可以是基站发送的Tx beam中的一个或多个,也可以不是基站发送的Tx beam,属于基站的其他Tx beam。
步骤4:UE将该一个或多个最优beam的RS ID上报给基站。
如果推理得到一个最优beam的RS ID,则将该beam的RS ID上报给基站;如果推理得到多个最优beam的RS ID,则选择一个beam的RS ID上报
给基站,或者都上报给基站,由基站选择一个。
如果UE用不同的RS配置训练、更新或Fine-tuning得到多个AI/ML模型,UE还需要将RS配置对应的model ID上报给基站,即UE不仅需要上报给基站预测得到的最优beam ID,也需要上报预测该beam的model的ID。
如果RS配置和训练、更新或Fine-tuning的model是一一对应的,那么终端也可以上报RS配置标识信息,代表上述model ID。
如果UE针对每个{输入Tx beam数,输出Tx beam数}对进行训练、更新或Fine-tuning得到一个AI model,那么{输入Tx beam数,输出Tx beam数}对信息可以代表model。即UE可以上报{输入Tx beam数,输出Tx beam数}对信息,代表上述model ID。
步骤5:基站根据RS ID和物理beam的映射关系,得到物理实际的最优beam,从而基站用该beam和UE进行通信。
因为RS配置是基站生成并配置的,所以基站根据RS ID和物理beam的映射关系,得到物理实际的最优beam,从而基站用该beam和UE进行通信。
如果UE用不同的RS配置训练、更新或Fine-tuning得到多个AI/ML模型,基站根据UE上报的model ID,或RS配置标识信息,或{输入Tx beam数,输出Tx beam数}对信息,得到UE使用该RS配置或{输入Tx beam数,输出Tx beam数}对训练、更新或Fine-tuning得到的model输出的beam ID和物理beam的映射关系,从而得到物理实际的最优beam,基站用该beam和UE进行通信。

步骤4:UE将该一个或多个最优beam的beam ID或者RS ID上报给基
站。
如果推理得到一个最优beam的beam ID或者RS ID,则将该beam的beam ID或者RS ID上报给基站;如果推理得到多个最优beam的beam ID或者RS ID,则选择一个beam的beam ID或者RS ID上报给基站,或者都上报给基站,由基站选择一个。
如果UE用不同的beam描述信息训练、更新或Fine-tuning得到多个AI/ML模型,UE还需要将beam描述信息对应的model ID上报给基站,即UE不仅需要上报给基站预测得到的最优beam ID,也需要上报预测该beam的model的ID。
如果beam描述信息和训练、更新或Fine-tuning的model是一一对应的,那么终端也可以上报beam描述信息的标识信息,代表上述model ID。
如果UE针对每个{输入Tx beam数,输出Tx beam数}对进行训练、更新或Fine-tuning得到一个AI model,那么{输入Tx beam数,输出Tx beam数}对信息可以代表model。即UE可以上报{输入Tx beam数,输出Tx beam数}对信息,代表上述model ID。
步骤5:基站根据beam ID或者RS ID和物理beam的映射关系,得到物理实际的最优beam,从而基站用该beam和UE进行通信。
因为beam描述信息是基站生成或者第三方生成并发给基站和UE的,所以基站根据beam ID或者RS ID和物理beam的映射关系,得到物理实际的最优beam,从而基站用该beam和UE进行通信。
如果UE用不同的beam描述信息训练、更新或Fine-tuning得到多个AI/ML模型,基站根据UE上报的model ID,或beam描述信息的标识信息,或{输入Tx beam数,输出Tx beam数}对信息,得到UE使用该beam描述信息或{输入Tx beam数,输出Tx beam数}对训练、更新或Fine-tuning得到的model输出的beam ID和物理beam的映射关系,从而得到物理实际的最优beam,基站用该beam和UE进行通信。
实施例五:基站基于数据集进行AI/ML模型的训练或更新。
步骤1:基站接收一个或多个数据集。
该一个或多个数据集,可以来自于UE或第三方设备。
数据集包括:数据集标识,一个或多个数据集样本。
数据集样本包括:多个beam ID,以及该beam ID对应的beam的RSRP(作为AI/ML模型(model)的训练、更新或Fine-tuning的输入),一个或多个最优的beam ID(作为AI/ML模型的训练、更新或Fine-tuning的输出标签)。
不同的beam ID实际上对应不同的物理beam(即实际发送的beam)。
这里的beam可以是beam pair,或者Tx beam,或者Rx beam。
步骤2:基站基于数据集进行AI/ML模型的训练、更新或Fine-tuning,得到对应的AI/ML模型。
如果基站用不同的数据集训练、更新或Fine-tuning,可以得到不同的AI/ML模型。不同的数据集,可以针对不同的应用场景,或者基站配置,或者AI功能。
其中,应用场景包括:城市,农村,室内,室外,高速公路,高铁,Uma,Umi等等;基站配置包括:基站天线配置,波束配置,参考信号配置等等;AI功能,主要包括空域预测、频域预测、时域预测、下行beam pair预测、下行Tx beam预测、下行Rx beam预测等等。其中,空域预测是指测量少量的beam,或者其他参考信号类型的beam,预测大量beam中的best beam;频域预测是指测量频率1上的beam,预测另一个频率2上的beam中的best beam;时域预测是指测量现在时刻的beam,预测未来时刻的best beam。
步骤3:UE对测量集合中的Tx beam上接收的RS进行测量,然后将测量结果反馈给基站,基站使用AI/ML模型进行最优波束预测,推理得到一个或多个最优beam ID。
如果是beam pair预测,UE使用不同的Rx beam对基站发送的每个Tx beam上的RS(例如,CSI-RS或者SSB)测量,得到每个Tx beam和Rx beam pair对应的RSRP;如果是Tx beam预测,UE使用一个Rx beam对基站发送的每个Tx beam上的RS(例如,CSI-RS或者SSB)测量,得到每个Tx beam对应的RSRP;如果是Rx beam预测,UE使用不同的Rx beam对基站发送的一个Tx beam上的RS(例如,CSI-RS或者SSB)测量,得到每个Rx beam
对应的RSRP。
UE上报测量结果给基站,由基站使用AI/ML模型进行波束预测。
上述RSRP作为AI/ML模型的输入,进行推理得到一个或多个最优beam ID。
其中,beam ID是指beam pair预测的最优beam pair中的Rx beam的beam ID,或Rx beam预测的最优Rx beam的beam ID,或Rx beam预测的最优Rx beam的beam ID。
推理得到一个或多个最优beam,可以是UE接收的Rx beam中的一个或多个,也可以不是UE接收的Rx beam,是UE的其他Rx beam。
步骤4:基站将该一个或多个最优beam ID发送给UE。
如果推理得到一个最优beam ID,则将该beam ID发送给UE;如果推理得到多个最优beam ID,则选择一个beam ID发送给UE,或者都发送给UE,由UE选择一个。
如果基站用不同的数据集训练、更新或Fine-tuning得到多个AI/ML模型,基站还需要将数据集对应的model ID发送给UE,即基站不仅需要发送给UE预测得到的最优beam ID,也需要发送预测该beam的model的ID。
如果数据集和训练、更新或Fine-tuning的model是一一对应的,那么基站也可以发送数据集标识信息,代表上述model ID。
如果基站针对每个{输入Tx beam数,输出Tx beam数}对进行训练、更新或Fine-tuning得到一个AI model,那么{输入Tx beam数,输出Tx beam数}对信息可以代表model。即基站可以发送{输入Tx beam数,输出Tx beam数}对信息,代表上述model ID。
步骤5:UE根据beam ID和物理beam的映射关系,得到物理实际的最优beam,从而UE用该beam和基站进行通信。
因为数据集是UE定义的或者是第三方定义但UE已知的(第三方需要告知UE该数据集中的beam ID和物理实际beam的对应关系),所以UE根据beam ID和物理beam的映射关系,得到物理实际的最优beam,从而UE用该beam和基站进行通信。
如果基站用不同的数据集训练、更新或Fine-tuning得到多个AI/ML模型,UE根据基站发送的model ID,或数据集标识信息,或{输入Tx beam数,输出Tx beam数}对信息,得到基站使用该数据集或{输入Tx beam数,输出Tx beam数}对训练、更新或Fine-tuning得到的model输出的beam ID和物理beam的映射关系,从而得到物理实际的最优beam,UE用该beam和基站进行通信。
实施例六:基站基于beam的描述信息进行AI/ML模型的训练、更新或Fine-tuning。
步骤1:基站接收一个或多个beam描述信息。
该一个或多个beam描述信息,可以是UE生成并发给基站,或者是第三方生成,并发给UE和基站。
Beam的描述信息包括,beam ID或者RS ID,以及该beam ID或者RS ID对应的beam的UE天线配置信息,beam的角度信息,和/或,beam的宽度信息。
如果有多个beam,可以按照beam ID列表的方式,分别描述。
上述Beam ID可以是UE接收Rx beam的编号,RS ID可以是UE在Rx beam上接收的RS的indication,例如,CSI-RS的indication为CRI,SSB的indication为SSBRI。
这里的beam可以是beam pair,或者Tx beam,或者Rx beam。
步骤2:基站基于beam描述信息,以及对Rx beam上配置的RS进行测量,根据测量结果进行AI/ML模型的训练、更新或Fine-tuning,得到对应的AI/ML模型。
如果基站基于不同的beam描述信息和测量结果,可以训练、更新或Fine-tuning得到不同的AI/ML模型。不同的beam描述信息,可以针对不同的应用场景,或者基站配置,或者AI功能。
其中,应用场景包括:城市,农村,室内,室外,高速公路,高铁,Uma,Umi等等;基站配置包括:基站天线配置,波束配置,参考信号配置等等;AI功能,主要包括空域预测、频域预测、时域预测、下行beam pair预测、下行Tx beam预测、下行Rx beam预测等等。其中,空域预测是指测量少量
的beam,或者其他参考信号类型的beam,预测大量beam中的best beam;频域预测是指测量频率1上的beam,预测另一个频率2上的beam中的best beam;时域预测是指测量现在时刻的beam,预测未来时刻的best beam。
步骤3:UE对测量集合中的Tx beam上发送的RS进行测量,然后将测量结果反馈给基站,基站使用AI/ML模型进行最优波束预测,推理得到一个或多个最优beam对应的beam ID或者RS ID。
如果是beam pair预测,UE使用不同的Rx beam对基站发送的每个Tx beam上的RS(例如,CSI-RS或者SSB)测量,得到每个Tx beam和Rx beam pair对应的RSRP;如果是Tx beam预测,UE使用一个Rx beam对基站发送的每个Tx beam上的RS(例如,CSI-RS或者SSB)测量,得到每个Tx beam对应的RSRP;如果是Rx beam预测,UE使用不同的Rx beam对基站发送的一个Tx beam上的RS(例如,CSI-RS或者SSB)测量,得到每个Rx beam对应的RSRP。
UE上报测量结果给基站,由基站使用AI/ML模型进行波束预测。
上述RSRP作为AI/ML模型的输入,进行推理得到一个或多个最优beam对应的beam ID或者RS ID。
其中,beam ID或者RS ID是指beam pair预测的最优beam pair中的Rx beam对应的beam ID或者RS ID,或Rx beam预测的最优Rx beam对应的beam ID或者RS ID,或Rx beam预测的最优Rx beam的beam ID或者RS ID。
推理得到一个或多个最优beam,可以是UE接收的Rx beam中的一个或多个,也可以不是UE接收的Rx beam,是UE的其他Rx beam。
步骤4:基站将该一个或多个最优beam的beam ID或者RS ID发送给UE。
如果推理得到一个最优beam的beam ID或者RS ID,则将该beam的beam ID或者RS ID发送给UE;如果推理得到多个最优beam的beam ID或者RS ID,则选择一个beam的beam ID或者RS ID发送给UE,或者都发送给UE,由UE选择一个。
如果基站用不同的beam描述信息训练、更新或Fine-tuning得到多个
AI/ML模型,基站还需要将beam描述信息对应的model ID发送给UE,即基站不仅需要发送给UE预测得到的最优beam ID,也需要发送预测该beam的model的ID。
如果beam描述信息和训练、更新或Fine-tuning的model是一一对应的,那么UE也可以发送beam描述信息的标识信息,代表上述model ID。
如果基站针对每个{输入Tx beam数,输出Tx beam数}对进行训练、更新或Fine-tuning得到一个AI model,那么{输入Tx beam数,输出Tx beam数}对信息可以代表model。即基站可以发送{输入Tx beam数,输出Tx beam数}对信息,代表上述model ID。
步骤5:UE根据beam ID或者RS ID和物理beam的映射关系,得到物理实际的最优beam,从而UE用该beam和基站进行通信。
因为beam描述信息是UE生成或者第三方生成并发给UE和基站的,所以UE根据beam ID或者RS ID和物理beam的映射关系,得到物理实际的最优beam,从而UE用该beam和基站进行通信。
如果基站用不同的beam描述信息训练、更新或Fine-tuning得到多个AI/ML模型,UE根据基站发送的model ID,或beam描述信息的标识信息,或{输入Tx beam数,输出Tx beam数}对信息,得到基站使用该beam描述信息或{输入Tx beam数,输出Tx beam数}对训练、更新或Fine-tuning得到的model输出的beam ID和物理beam的映射关系,从而得到物理实际的最优beam,UE用该beam和基站进行通信。
