CSI、终端设备的AI模型的相关信息、终端设备的感知网络的相关信息,系统性能的相关信息。
下面分情况对该过程进行说明。
情况1:
第一信息的获取方式为:通过参考信号的测量获取(例如,第一信息的类型为CSI或感知网络的相关信息)。
网络设备可以在第一信息对应的测量资源上向终端设备发送参考信号。相应地,终端设备可以根据第一信息对应的参考信号(例如参考信号对应的序列)、第一信息对应的测量资源,接收来自网络设备的参考信号,并对参考信号进行测量得到第一信息,进一步地,根据第一信息的反馈资源、反馈周期向网络设备发送该第一信息。
一种可能的实现中,终端设备在经过测量得到第一信息的过程中,可以根据第一信息的量化粒度生成第一信息。
例如,终端设备根据第一信息的量化粒度,确定将第一信息承载于3个比特中,则在生成第一信息的过程中,终端设备用3个比特指示该第一信息。
情况2:
第一信息不需要通过参考信号的测量获取。在此情况下,网络设备不需要发送参考信号,终端设备也不需要对参考信号进行测量,终端设备可以直接获取第一信息,并根据第 一信息的反馈资源、反馈周期向网络设备发送该第一信息。
此外,终端设备直接获取第一信息的过程中,可以根据第一信息的量化粒度生成第一信息。
S203,网络设备根据第一信息,对网络设备的AI模型进行辅助。
在该过程中,网络设备可以将第一信息作为输入,辅助AI模型进行训练,推演,验证,测试等操作。
下面通过几个例子对该过程进行说明:
例1:
第一信息包括第一CSI,网络设备可以将第一CSI作为输入,训练网络设备的AI模型。网络设备的AI模型可以用来预测第二CSI。第一CSI和第二CSI为不同时刻或不同端口的CSI。
作为一种可能的情况,该预测过程可以包括如下步骤:
步骤1:网络设备通过下行信道在第一时刻向终端设备发送CSI-RS。
步骤2:终端设备对CSI-RS进行测量,获取下行信道在第一时刻的第一CSI。
步骤3:终端设备向网络设备发送下行信道在第一时刻的第一CSI。
步骤4:网络设备根据下行信道在第一时刻的第一CSI,利用AI模型预测下行信道在第二时刻的第二CSI。
例如,网络设备可以基于深度神经网络模型进行预测,或者基于卡尔曼预测模型进行预测,或者基于普罗尼(prony)方法进行预测,或者基于线性或非线性预测算法进行预测,本申请对此不予限制。关于网络设备预测时采用的方法或模型,下文不再赘述。
作为另一种情况,该预测过程可以包括如下步骤:
步骤1:网络设备通过第一端口在第一时刻向终端设备发送CSI-RS。
步骤2:终端设备对CSI-RS进行测量,获取第一端口在第一时刻的第一CSI。
步骤3:终端设备向网络设备发送第一端口在第一时刻的第一CSI。
步骤4:网络设备根据第一端口在第一时刻的CSI,利用AI模型预测第二端口在第一时刻的第二CSI。
例2:
第一信息包括第一时刻的BLER,网络设备可以将第一时刻的BLER作为输入,训练网络设备的AI模型。该AI模型可以用来预测第二时刻的BLER。
例3:
第一信息包括第一时刻终端设备的位置信息,网络设备可以将第一时刻终端设备的位置信息作为输入,训练网络设备的AI模型。该AI模型可以用来预测第二时刻终端设备的位置信息。
根据本申请的方法,终端设备可以根据第一配置信息,向网络设备发送第一信息。第一配置信息包括第一信息的类型,还可以包括除类型之外的其他配置信息,例如第一信息的量化粒度,第一信息的反馈资源,第一信息的反馈周期,第一信息对应的测量资源,第一信息对应的参考信号,第一信息对应的参考信号与第一信息对应的测量资源之间的映射关系。
因此,终端设备可以基于第一配置信息灵活地发送第一信息。例如可以发送不同类型 的第一信息,每种类型的第一信息的配置信息可以不同,例如不同类型的第一信息的反馈资源可以不同。此外针对同一种类型的第一信息的配置信息也可以不同,例如终端设备的AI模型的相关信息可以用不同的周期或者资源进行反馈。相比于终端设备基于同一种配置信息发送第一信息,采用本申请的方法可以提高资源的利用效率,提高系统的频谱利用效率。
可选地,如果网络设备的AI模型、终端设备的AI模型、终端设备的感知网络、终端设备和网络设备之间的信道状态中的一项或多项更新,该方法还包括:
S204,终端设备获取第二配置信息。
具体地,终端设备获取第二配置信息的方式包括:终端设备自行确定第二配置信息,或者终端设备从网络设备获取第二配置信息。详细过程可以参考下述方法300至方法600。
第二配置信息用于更新第一配置信息,第一配置信息与第二配置信息不同。
具体地,第二配置信息用于更新第一配置信息中的以下一项或多项:
第一信息的类型,第一信息的量化粒度,第一信息的反馈资源,第一信息的反馈周期,第一信息对应的测量资源,第一信息对应的参考信号,第一信息对应的参考信号与第一信息对应的测量资源之间的映射关系。
例如,在S204之前,第一信息的量化粒度为M1比特,在S204中将第一信息的量化粒度更新为M2比特。
又例如,在S204之前,第一信息的反馈周期为单次反馈,在S204中将第一信息的反馈周期更新为以T为周期反馈N次。
又例如,在S204之前,终端设备需要向网络设备反馈CSI;在S204中,终端设备根据第二配置信息不再向网络设备反馈CSI。
根据本申请的方法,当网络设备的AI模型、终端设备的AI模型、终端设备的感知网络、终端设备和网络设备之间的信道状态中的一项或多项更新时,第一信息对应的第一配置信息也相应更新,更新后的第一配置信息与网络设备的AI模型、终端设备的AI模型、终端设备和网络设备之间的信道状态、或者终端设备的感知网络的适配度会更好,从而保证第一信息测量和反馈流程的有效性。
下面结合图3-图6对方法200作进一步描述。
图3示出了方法300,在该方法300中,终端设备获取第一信息对应的第一配置信息的方式为:终端设备自行确定第一配置信息。具体地,该方法300包括:
S301,终端设备确定第一信息对应的第一配置信息。关于该第一配置信息的描述可以参考S201。
具体地,终端设备可以根据第一信息的类型,确定第一配置信息中的一些参数。换句话说,第一配置信息中的一些参数与第一信息的类型相关。
一种可能的实现中,终端设备可以根据第一信息的服务质量要求,确定第一信息的量化粒度。
示例性的,如果第一信息的服务质量要求低于第一阈值,终端设备确定第一信息对应第一量化粒度;如果第一信息的服务质量要求大于或等于第一阈值,终端设备确定第一信息对应第二量化粒度;第二量化粒度小于第一量化粒度。
因此,根据本申请的方法,如果第一信息的服务质量要求较低,可以基于较大的量化 粒度(较少的比特数)传输第一信息,从而可以节省资源。
一种可能的实现中,终端设备可以根据第一信息的变化频率,确定第一信息的反馈周期。
示例性的,如果第一信息的变化频率大于第二阈值(换句话说,该第一信息具有时变特性),终端设备确定第一信息对应第一反馈周期;如果第一信息的变化频率小于或等于第二阈值(换句话说,该第一信息具有缓变特性),终端设备确定第一信息对应第二反馈周期;第二反馈周期大于第一反馈周期。
例如,对于误块率、误比特率、误码块组率、终端设备位置、终端设备速度、周边环境信息等,终端设备可以采用较长的反馈周期进行反馈,或者终端设备可以仅向网络设备反馈一次(相当于反馈周期无限大);对于与信道相关的信息(例如,CSI),终端设备可以采用较短的反馈周期进行反馈。
因此,根据本申请的方法,如果第一信息具有时变特性,则第一信息的反馈周期较短,从而避免反馈不及时的情况发生;如果第一信息具有缓变特性,则第一信息的反馈周期较长,从而可以节省资源。
一种可能的实现中,终端设备可以从网络设备配置的多个反馈资源中确定第一信息的反馈资源。
示例性的,网络设备预先向终端设备配置了第一反馈资源和第二反馈资源。终端设备可以从上述2个反馈资源中确定第一信息的反馈资源。
例如,终端设备可以根据第一信息的数据量大小从上述2个反馈资源中确定第一信息的反馈资源。第一信息的数据量大小为第一信息包括的数据的个数,例如第一信息包括的比特个数或字节个数。
具体地,如果第一信息的数据量大于第三阈值,则终端设备从上述2个反馈资源中选择包括时隙(slot)、符号(symbol)、资源单元(resource element,RE)或资源块(resource block,RB)个数较多的反馈资源;如果第一信息的数据量小于或等于第三阈值,则终端设备从上述2个反馈资源中选择包括slot、symbol、RE或RB个数较少的反馈资源。
又例如,网络设备可以向终端设备发送网络设备的AI模型的调整幅度信息,终端设备可以根据网络设备的AI模型的调整幅度信息从上述2个反馈资源中确定第一信息的反馈资源。
具体地,如果网络设备的AI模型的调整幅度大于第四阈值,则终端设备从上述2个反馈资源中选择包括slot、symbol、RE或RB个数较多的反馈资源;如果网络设备的AI模型的调整幅度小于或等于第四阈值,则终端设备从上述2个反馈资源中选择包括slot、symbol、RE或RB个数较少的反馈资源。
因此,根据本申请的方法,终端设备可以灵活地确定第一信息的反馈资源,避免资源的浪费。

示例性的,网络设备预先给终端设备配置了测量资源#1和测量资源#2。终端设备可以从上述2个测量资源中确定第一信息对应的测量资源。
例如,终端设备可以根据第一信息的类型确定第一信息对应的测量资源。当第一信息 的类型为感知网络的相关信息时,例如,多径的数量,每条路径的距离,多普勒偏移或多普勒扩展时,获取第一信息需要较多的测量资源,终端设备可以从上述2个测量资源中选择包括slot、symbol、RE或RB个数较多的测量资源。
因此,根据本申请的方法,终端设备可以灵活地确定第一信息对应的测量资源,避免资源的浪费。
可选地,作为一种方式,终端设备也可以自行确定第一信息对应的参考信号、第一信息对应的参考信号与第一信息对应的测量资源之间的映射关系。
作为一种实现方式,终端设备可以根据基序列生成伪随机序列,该伪随机序列中包括一些参数,这些参数与终端设备的配置(例如,符号个数、帧结构的配置、终端设备的加扰标识(ID))相关。进一步地,终端设备从该伪随机序列中确定第一信息对应的参考信号的生成序列。再进一步地,终端设备根据预配置的规则或算法,确定该生成序列中的不同符号对应的测量资源(例如,时域资源、频域资源、码域资源)。
可选地,作为另一种方式,网络设备可以向终端设备配置第一信息对应的参考信号、第一信息对应的参考信号与第一信息对应的测量资源之间的映射关系。换言之,对于这些信息,终端设备可能无法自行确定。
此外,上述各种可能的实现并不是孤立的,相互之间可以结合。

又例如,终端设备将自行确定的第一信息对应的测量资源和/或第一信息对应的参考信号上报给网络设备,网络设备可以在终端设备确定的测量资源发送终端设备确定的参考信号。

又例如,更新前网络设备的AI模型具有预测终端设备位置的能力,第一指示信息指示更新后网络设备的AI模型不具有预测终端设备位置的能力,则终端设备更新第一信息的类型,更新后第一信息的类型不再包括终端设备位置。即,终端设备不再向网络设备反馈终端设备的位置信息。
一种可能的实现中,终端设备确定终端设备的AI模型更新,终端设备根据更新后的终端设备的AI模型确定第二配置信息。
例如,更新前终端设备侧的AI模型的梯度变化较为缓慢,终端设备基于较长的反馈周期向网络设备反馈终端设备的AI模型的梯度;更新后终端设备的AI模型的梯度变化较为频繁,终端设备基于较短的反馈周期向网络设备反馈终端设备的AI模型的梯度。
