目前,在新空口(New Radio,NR)系统中,终端在向网络侧设备发送多个上行信道时,可以被使能解调参考信号(Demodulation Reference Signal,DMRS)绑定bundling,则终端在该多个上行信道传输对应的时间窗(Time Domain Window,TDW)内保持相位连续性和功率一致性,以使得网络侧设备可以根据一个上行信道映射的DMRS,估计/推测/获得对于其他上行信道传输的信道信息,从而网络侧设备可以联合该多个上行信道进行联合信道估计,获得更好的信道估计准确度,提升网络侧设备的接收性能,达到提高覆盖能力的效果。
但是,由于在标准Release 18中会考虑在非地面网络(Non-Terrestrial Networks,NTN)下支持DMRS bundling特性,这样会引入新的半静态事件或动态事件,导致TDW内的相位连续性和功率一致性不能保持。此时,终端需要上报能力,指示是否支持在半静态事件或动态后重新进行DMRS bundling(即重新开始一个实际上的时间窗actual TDW)的能力。

以下将对本申请实施例涉及的术语进行说明。
1、终端重新进行DMRS bundling
目前,网络侧设备可以为终端配置名义上的时间窗nominal TDW,从而终端在向网络侧设备发送多个上行信道时,可能使能DMRS bundling,这样终端可以在该多个上行信道中的一个上行信道中映射DMRS,并在nominal TDW中,保持上行信道的相位连续性和功率一致性,以使得网络侧设备可以根据该一个上行信道映射的DMRS,对该多个上行信道进行联合信道估计。其中,从上行传输的第一个时隙开始,以网络配置nominal TDW的大小,在上行传输的duration内,连续地划分为一个或多个nominal TDW。
通常,在一个nominal TDW内,若发生半静态事件或动态事件,则会导致终端无法保持上行信道的相位连续性和功率一致性,此时,终端可以将一个nominal TDW划分为一个 或多个实际上的时间窗Actual TDW,并在每个Actual TDW内使能DMRS bundling,以使得网络侧设备可以对每个Actual TDW对应的上行信道进行联合信道估计。
其中,可以默认终端具备因发生半静态事件破坏相位连续性或功率一致性后,可以重启restart一个新的Actual TDW的能力,即默认终端具备因发生半静态事件破坏相位连续性或功率一致性后,可以重新进行DMRS bundling的能力。
若终端不具备因发生动态事件破坏相位连续性或功率一致性后,restart一个新的Actual TDW的能力时,在该动态事件发生后直至当前nominal TDW的结束时刻,均不会restart一个新的Actual TDW,即在该动态事件发生后直至当前nominal TDW的结束时刻,终端均不会重新进行DMRS bundling。
若终端具备因发生动态事件破坏相位连续性或功率一致性后,restart一个新的Actual TDW的能力时,在发生该动态事件后终端会restart一个新的Actual TDW,直至下一个动态事件(或半静态事件)的发生时刻或当前nominal TDW的结束时刻。
2、动态事件
动态事件,是指由下行控制信息(Downlink Control Information,DCI)或媒体访问控制地址(MediumAccessControl,MAC)控制元素(Control Element,CE)触发的,破坏TDW内相位连续性和或功率一致性的事件。其中,动态事件不包括配置跳频传输。
示例性地,动态事件可以包括:终端接收一个DCI,该一个DCI携带用于配置终端调整功率的配置。
3、半静态事件
半静态事件,是指破坏TDW内相位连续性和或功率一致性的事件中,除动态事件外的事件。半静态事件主要是由系统消息或无线资源控制(Radio Resource Control,RRC)参数进行配置的,例如配置跳频传输、配置两个物理上行共享信道(Physical Uplink Shared Channel,PUSCH)重复传输使用不同半静态调度(Semi-Persistent-Scheduling,SPS)资源集关联resource set association、配置两个PUCCH重复传输使用不同的空间关系(Spatial Relations)或功率控制参数(Power Control Parameters)等。

下面结合附图,通过一些实施例及其应用场景对本申请实施例提供的能力指示方法、装置、终端、网络侧设备及可读存储介质进行详细地说明。
目前,在NR系统中,终端在向网络侧设备发送多个上行信道时,可以被使能DMRS bundling,则终端在该多个上行信道传输对应的TDW内保持相位连续性和功率一致性,以使得网络侧设备可以根据该一个上行信道映射的DMRS,估计/推测/获得对于其他上行信道传输的信道信息,从而网络侧设备可以联合该多个上行信道进行联合信道估计,获得更好的信道估计准确度,提升网络侧设备的接收性能,达到提高覆盖能力的效果。但是,由于在Release 18中会考虑在NTN下支持DMRS bundling特性,这样会引入新的半静态事件或动态事件,导致TDW内的相位连续性和功率一致性不能保持。此时,终端需要上报能力, 指示是否支持在半静态事件或动态后重新进行DMRS bundling(即重新开始一个实际上的时间窗Actual TDW)的能力。因此,在终端支持接入TN和NTN进行通信的情况下,如何上报终端在NTN和TN下重新进行DMRS bundling的能力成为亟待解决的问题。
然而,在本申请实施例中,终端可以向网络侧设备发送指示终端在NTN和TN中的至少一个网络下是否支持重新进行DMRS bundling的能力的指示信息;其中,终端接入NTN,或者,指示信息指示的能力包括终端在NTN下是否支持重新进行DMRS bundling的能力。由于终端可以向网络侧设备发送目标指示信息,以向网络侧设备指示终端在NTN和TN中的至少一个网络下是否支持重新进行DMRS bundling的能力,因此,可以解决在终端可接入TN和NTN进行通信的情况下,如何上报终端在NTN和TN下重新进行DMRS bundling的能力的问题,从而网络侧设备可以根据终端在NTN和TN中的至少一个网络下是否支持重新进行DMRS bundling的能力,确定对终端发送的上行信道进行联合信道估计的方式,如此,可以提高终端发送上行信道的性能。
图2示出了本申请实施例提供的一种能力指示方法的流程图。如图2所示,本申请实施例提供的能力指示方法可以包括下述的步骤101。
步骤101、终端向网络侧设备发送目标指示信息。

可选地,本申请实施例中,终端在目标网络下是否支持重新进行DMRS bundling的能力可以为以下任一项:
在目标网络下支持重新进行DMRS bundling;
在目标网络下不支持重新进行DMRS bundling。
其中,在终端在目标网络下支持重新进行DMRS bundling的情况下,终端可以在接收到配置信令(该配置信令用于配置特定事件)的情况下,可以在该配置信令的生效时刻,重启一个新的Actual TDW,并在该新的Actual TDW的起始时刻至当前nominal TDW的结束时刻(或下一个特定时刻)之间的上行信道时,重新进行DMRS bundling。该特定事件可以为下述实施例中的半静态事件,和/或动态事件。
需要说明的是,上述“当前nominal TDW”可以理解为:配置信令的生效时刻所在的nominal TDW。
具体地,终端可以在新的Actual TDW的起始时刻至当前nominal TDW的结束时刻(或下一个特定时刻)保持上行信道的相位连续性和功率一致性,以使得网络侧设备可以根据一个上行信道映射的DMRS,估计/推测/获得对于其他上行信道传输的信道信息,从而网络侧设备可以联合多个上行信道进行联合信道估计。
在终端在目标网络下不支持重新进行DMRS bundling的情况下,终端并不会重启一个新的Actual TDW,而是结束上一个Actual TDW,直到下一个动态事件(或半静态事件)的发生时刻或当前nominal TDW的结束时刻。
可选地,本申请实施例中,在终端可接入NTN和TN的情况下,终端在NTN下是否支持重新进行DMRS bundling的能力,和终端在TN下是否支持重新进行DMRS bundling的能力可以相同或不同。
可以理解,在终端在NTN下是否支持重新进行DMRS bundling的能力,和终端在TN下是否支持重新进行DMRS bundling的能力相同的情况下,目标网络可以为TN,即目标指示信息指示终端可以上报终端在TN下支持重新进行DMRS bundling,从而网络侧设备可以根据终端在TN下支持重新进行DMRS bundling,确定终端在NTN下支持重新进行DMRS bundling,即终端可以重用在TN下的能力指示(即目标指示信息)。
在终端在NTN下是否支持重新进行DMRS bundling的能力,和终端在TN下是否支持重新进行DMRS bundling的能力不同的情况下,目标网络可以为NTN和TN中的至少一个,即终端可以相对独立上报终端在NTN下是否支持重新进行DMRS bundling的能力,和终端在TN下是否支持重新进行DMRS bundling的能力。
可选地,本申请实施例中,在终端接入NTN的情况下,目标网络包括NTN。
可以理解,在终端接入NTN的情况下,终端可以向网络侧设备上报终端在NTN下是否支持重新进行DMRS bundling的能力。
如此可知,由于在终端接入NTN的情况下,终端可以向网络侧设备上报终端在NTN和TN下是否支持重新进行DMRS bundling的能力,以使得网络侧设备可以确定终端在TN下是否支持重新进行DMRS bundling的能力,进而网络侧设备可以确定终端是否适合切换至TN,以使得终端可以接入适合的网络。
可选地,本申请实施例中,在终端接入TN的情况下,目标网络包括NTN。
可以理解,在终端接入TN的情况下,终端可以向网络侧设备上报终端在NTN下是否支持重新进行DMRS bundling的能力。
如此可知,由于在终端接入TN的情况下,终端可以向网络侧设备上报终端在NTN下是否支持重新进行DMRS bundling的能力,以使得网络侧设备可以确定终端在NTN下是否支持重新进行DMRS bundling的能力,进而网络侧设备可以确定终端是否适合切换至NTN,以使得终端可以接入适合的网络。
本申请实施例提供的能力指示方法,终端可以向网络侧设备发送指示终端在目标网络(即NTN和TN中的至少一个)下是否支持重新进行DMRS bundling的能力的目标指示信息;其中,终端接入NTN,或者,目标网络包括NTN。由于终端可以向网络侧设备发送目标指示信息,以向网络侧设备指示终端在NTN和TN中的至少一个网络下是否支持重新进行DMRS bundling的能力,因此,可以解决在终端可接入TN和NTN进行通信的情况下,如何上报终端在NTN和TN下是否支持重新进行DMRS bundling的能力的问题,从而网络侧设备可以根据终端在NTN和TN中的至少一个网络下是否支持重新进行DMRS bundling的能力,确定对终端发送的上行信道进行联合信道估计的方式,如此,可以提高终端发送上行信道的性能。
可选地,本申请实施例中,上述是否支持重新进行DMRS bundling的能力包括以下至少一项:
是否支持在半静态事件发生之后重新进行DMRS bundling的能力;
是否支持在动态事件发生之后重新进行DMRS bundling的能力。
其中,在终端在目标网络下支持在半静态事件发生之后重新进行DMRS bundling的情况下,终端可以在半静态事件的发生时刻,重启一个新的Actual TDW,并在该新的Actual TDW的起始时刻至当前nominal TDW的结束时刻(或下一个半静态事件的发生时刻)之间的上行信道时,重新进行DMRS bundling。
具体地,在终端从网络侧设备接收到配置信令的情况下,终端可以识别该配置信令中的事件标识,并在识别到该事件标识指示半静态事件的情况下,将该配置信令的生效时刻,确定为半静态事件的发生时刻,从而终端可以在半静态事件的发生时刻,重启一个新的Actual TDW。
其中,在终端在目标网络下支持在动态事件发生之后重新进行DMRS bundling的情况下,终端可以在动态事件的发生时刻,重启一个新的Actual TDW,并在该新的Actual TDW的起始时刻至当前nominal TDW的结束时刻(或下一个动态事件的发生时刻)之间的上行信道时,重新进行DMRS bundling。
具体地,在终端从网络侧设备接收到配置信令的情况下,终端可以识别该配置信令中的事件标识,并在识别到该事件标识指示动态事件的情况下,将该配置信令的生效时刻,确定为动态事件的发生时刻,从而终端可以在动态事件的发生时刻,重启一个新的Actual TDW。
可选地,本申请实施例中,终端接入NTN;上述目标网络为TN;目标指示信息指示的能力,用于确定终端在NTN下是否支持在动态事件发生之后重新进行DMRS bundling的能力。
可以理解,在本实施例中,在终端可接入NTN和TN的情况下,终端可以重用在TN下的能力指示(即目标指示信息)的能力标识位,即可以通过向网络侧设备发送在TN下的能力指示,以指示终端在NTN和TN下是否支持在动态事件发生之后重新进行DMRS  bundling的能力。
可选地,本申请实施例中,终端在NTN下是否支持在动态事件发生之后重新进行DMRS bundling的能力,和终端在TN下是否支持在动态事件发生之后重新进行DMRS bundling的能力相同。
示例性地,若目标指示信息指示终端在TN下支持在动态事件发生之后重新进行DMRS bundling,则终端在NTN下也支持在动态事件发生之后重新进行DMRS bundling。
可选地,本申请实施例中,在终端可接入NTN和TN的情况下,可以默认终端在NTN或TN下支持在半静态事件发生之后重新进行DMRS bundling。
可以理解,终端在NTN或TN下支持在半静态事件发生之后重新进行DMRS bundling为终端的强制性mandatory功能。即在半静态事件发生之后,终端会可以重启一个新的Actual TDW,并在该新的Actual TDW的起始时刻至当前nominal TDW的结束时刻(或下一个半静态事件的发生时刻)之间的上行信道时,重新进行DMRS bundling。
如此可知,由于终端上报的终端在TN下是否支持在动态事件发生之后重新进行DMRS bundling的能力,可以确定终端在NTN下是否支持在动态事件发生之后重新进行DMRS bundling的能力,而无需终端上报终端在NTN和TN下是否支持在动态事件发生之后重新进行DMRS bundling的能力,因此,可以减少终端上报能力的次数,如此,可以节省上报资源。
可选地,本申请实施例中,终端默认终端在NTN下支持在半静态事件发生之后重新进行DMRS bundling。
本申请实施例中,在终端可接入NTN和TN的情况下,终端可以默认终端在NTN下支持在半静态事件发生之后重新进行DMRS bundling。此时,若目标指示信息指示终端在目标网络下支持在动态事件发生之后重新进行DMRS bundling,则可以认为终端在NTN和/或TN下支持在动态事件发生之后重新进行DMRS bundling;若目标指示信息指示终端在目标网络下不支持在动态事件发生之后重新进行DMRS bundling,则可以认为终端在NTN和/或TN不下支持在动态事件发生之后重新进行DMRS bundling。
如此可知,由于可以默认终端在NTN下支持在半静态事件发生之后重新进行DMRS bundling,这样终端可以仅向网络侧设备示终端在目标网络下是否支持在动态事件发生之后重新进行DMRS bundling的能力,因此,可以减少目标指示信息的数据量。
可选地,本申请实施例中,上述目标网络包括NTN;上述目标指示信息指示终端在NTN下是否支持在动态事件发生之后重新进行DMRS bundling的能力。
可选地,本申请实施例中,在终端接入NTN的情况下,目标网络包括NTN,目标指示信息指示终端在NTN下是否支持在动态事件发生之后重新进行DMRS bundling的能力。
可以理解,在终端接入NTN的情况下,终端在NTN下是否支持重新进行DMRS bundling的能力为终端在NTN下是否支持在动态事件发生之后重新进行DMRS bundling的能力,并且终端可以针对终端在NTN和TN下是否支持重新进行DMRS bundling的能力是独立指示 的。
如此可知,由于终端可以独立的向网络侧设备上报终端在NTN下是否支持重新进行DMRS bundling的能力,因此,可以提高终端向网络侧设备上报终端能力的灵活性。
可选地,本申请实施例中,上述目标网络包括NTN;上述目标指示信息包括以下任一项:第一能力等级、第二能力等级以及第三能力等级。
本申请实施例中,上述第一能力等级,指示终端在NTN下不支持在半静态事件发生之后重新进行DMRS bundling,且不支持在动态事件发生之后重新进行DMRS bundling;
可以理解,在目标指示信息为第一能力等级的情况下,终端在半静态事件和/或动态事件发生之后,不支持重新进行DMRS bundling,直至当前nominal TDW结束。
本申请实施例中,上述第二能力等级,指示终端在NTN下支持在半静态事件发生之后重新进行DMRS bundling,且不支持在动态事件发生之后重新进行DMRS bundling。
可以理解,在目标指示信息为第二能力等级的情况下,终端在半静态事件发生之后,可以重新进行DMRS bundling;而在动态事件发生之后,不支持重新进行DMRS bundling,直至下一个动态事件(或半静态事件)的发生时刻或当前nominal TDW结束。
本申请实施例中,上述第三能力等级,指示终端在NTN下支持在半静态事件发生之后重新进行DMRS bundling,且支持在动态事件发生之后重新进行DMRS bundling。
可以理解,在目标指示信息为第三能力等级的情况下,终端在半静态事件发生之后,可以重新进行DMRS bundling;且在动态事件发生之后,可以重新进行DMRS bundling。
如此可知,由于第一能力等级、第二能力等级以及第三能力等级中的每个能力等级均指示终端在NTN下是否支持在半静态事件发生之后重新进行DMRS bundling的能力,和在动态事件发生之后重新进行DMRS bundling的能力,即每个能力等级均指示终端在NTN下的多个能力,因此,终端可以通过上报第一能力等级、第二能力等级以及第三能力等级中的任一个能力等级,以上报终端在NTN下的多个能力,而无需分别上报终端在NTN下的每个能力,因此,可以节省上报资源。
