在一些实施例中，上述中继设备可以支持波束赋形技术，例如，该中继设备可以根据网络设备的控制，在进行无线信号转发时应用特定的波束进行转发。但是，在相关技术中，中继设备在应用波束的方式不够灵活，特别是无法针对波束应用的时域信息进行有效的控制，导致中继设备无法更有效地提升覆盖性能。
为了解决上述问题，本公开提供了一种波束应用方法、装置、存储介质及芯片。

需要说明的是，Side Control Information是网络设备向中继设备发送的控制信息，这里SCI也可以是用于网络设备向中继设备发送控制信息的信令，该SCI可以理解为中继设备使用的一种特定DCI。
方式三、在中继设备未接收到网络设备发送的波束时域信息的情况下，中继设备可以将预设时域信息作为该目标波束对应的波束时域信息。
其中，该预设时域信息可以是中继设备预先设置的任意信息。在一些实施例中，该预设时域信息通过协议约定。
中继设备可以在满足以下任意一个或多个条件的情况下，确定中继设备未接收到网络设备发送的波束时域信息：
条件一、中继设备接收到的第一消息中不包括所述波束时域信息。
条件二、中继设备接收到的第一消息中不包括所述波束时域信息，且未接收到第二消息。
条件三、中继设备接收到的第一消息和第二消息中均不包括所述波束时域信息。
条件四、中继设备接收到的第一消息或第二消息中包括所述波束时域信息，但是该波束时域信息校验失败，导致中继设备无法获取正确的波束时域信息。例如，该波束时域信息中的某些参数的值超出预设参数取值范围导致校验失败。
这样，中继设备可以通过上述任意一种方式，确定上述波束时域信息。
S303、中继设备在根据所述波束时域信息确定的应用时间内，应用所述目标波束。
在一些实施例中，中继设备可以在应用时间内通过该目标波束向终端设备发送无线信号。例如，可以将从网络设备接收到的无线信号，通过该目标波束转发至终端设备。
在一些实施例中，中继设备可以在应用时间内通过该目标波束接收终端设备发送的无线信号。例如，可以将通过该目标波束接收到的终端设备发送的无线信号，转发至网络设备。
采用上述方法，中继设备响应于接收到网络设备发送的第一消息，确定目标波束，并确定所述目标波束对应的波束时域信息，在根据所述波束时域信息确定的应用时间内，应用所述目标波束。其中，该目标波束为应用于所述中继设备与终端设备之间的传输链路的波束，所述目标波束包括一个或者多个波束，或者一个或者多个波束组。这样，中继设备可以根据波束时域信息，灵活应用目标波束，以便更加有效地通过目标波束提升覆盖性能。
在本公开的一些实施例中，上述波束时域信息可以包括以下信息中的一项或多项：
信息一、所述目标波束对应的波束开始时刻信息。
其中，该波束开始时刻信息可以用于指示中继设备开始应用该目标波束的第一时刻。
示例地，在所述波束时域信息包括目标波束对应的波束开始时刻信息的情况下，中继设备可以根据波束开始时刻信息确定第一时刻；在所述中继设备的当前时刻到达该第一时刻的情况下，应用该目标波束。
该第一时刻可以是一个特定时隙(slot)位置，也可以是一个特定时隙中的特定符号
(symbol)位置。需要说明的是，该第一时刻可以是通过消息中的波束开始时刻参数直接指示的；也可以是根据用于激活该目标波束的MAC CE所在的slot位置计算得到的，计算该第一时刻的规则可以是预先设定的特定规则，例如通过协议规定该特定规则。本公开对此不作限定。

示例地，在所述波束时域信息包括目标波束对应的波束结束时刻信息的情况下，中继设备可以根据波束结束时刻信息确定结束时刻；在所述中继设备的当前时刻到达该结束时刻的情况下，停止应用该目标波束。
在一些实施例中，上述波束时域信息可以同时包括波束开始时刻信息和波束结束时刻信息；
在一些实施例中，波束结束时刻是根据去激活该目标波束的MACCE所在的时隙slot位置计算得到，计算该结束时刻的规则可以是预先设定的特定规则，本公开对此不作限定。
在一些实施例中，波束结束时刻是根据波束开始时刻和第二时长计算得到的，示例地，该波束结束时刻可以是波束开始时刻与该第二时长相加后得到的时刻。
其中，该第二时长可以是激活该目标波束的MAC CE中携带的时长；该第二时长也可以是第一消息中携带的时长；该第二时长还可以是中继设备预先设定的时长，本公开对此不作限定。
需要说明的是，在目标波束以周期的方式进行应用的情况下，该第二时长还可以用于指示目标波束应用的周期数目。示例地，该第二时长可以指示中继设备在波束开始时候后应用该目标波束总共100个周期，在100个周期后可以停止应用该目标波束。
这样，中继设备可以通过波束开始时刻信息确定应用该目标波束的第一时刻，通过波束结束时刻信息确定应用该目标波束的结束时刻，在第一时刻和结束时刻之间的时间段内，应用该目标波束，通过该目标波束对无线信号进行转发。
同样地，该结束时刻可以是一个特定时隙位置，也可以是一个特定时隙中的特定符号位置。

其中，该波束周期信息可以用于指示中继设备周期性应用该目标波束。
示例地，在所述波束时域信息包括该波束周期信息的情况下，中继设备可以根据该波束周期信息确定目标周期；根据该目标周期，周期性为所述中继设备应用所述目标波束。
在一些实施例中，该目标周期可以是时隙的倍数，例如，可以用N个时隙的方式进行表示。
信息四、所述目标波束对应的波束应用时长信息。
其中，该波束应用时长信息可以用于指示中继设备应用目标波束的时间长度。
在一些实施例中，对于周期性应用的目标波束(例如通过波束周期信息指示的周期性波束或半静态波束)，该波束应用时长信息可以用于指示中继设备单次应用该目标波束的时间长度，也就是目标波束在一次应用时机(occasion)内的波束应用时间长度。
需要说明的是，目标波束可以为一个或多个波束，在目标波束为一个波束的情况下，该波束应用时长信息可以用于指示中继设备应用该一个波束的时间长度。
在目标波束为多个波束的情况下，该波束应用时长信息可以有多种实现方式，示例地：
在一些实现方式中，该波束应用时长信息可以包括每个目标波束对应的第一持续时长。这样，中继设备可以根据第一持续时长和预设顺序，依次为所述中继设备应用所述目标波束。
在另一些实现方式中，该波束应用时长信息可以包括多个目标波束的持续总时长。这样，中继设备可以根据所述持续总时长和所述目标波束的数目，确定每个目标波束的第二持续时长；根据所述第二持续时长和预设顺序，依次为所述中继设备应用所述目标波束。
需要说明的是，上述预设顺序可以是根据目标波束的波束标识的大小确定，例如，按照波束标识从大到小的顺序排列，或者按照波束标识从小达到的顺序排列。上述预设顺序也可以根据目标波束在第一消息中的顺序确定，例如，按照目标波束在第一消息中出现的顺序从前到后排列，或者，从后到前排列。本公开对于预设顺序的排序方式不作限定。
在一些实施例中，上述波束应用时长信息可以包括以下信息中的一项或多项：
波束应用时长信息一、应用所述目标波束的应用时间范围。
在一些实现方式中，该应用时间范围可以包括绝对时间范围，例如，可以是起始时间到终止时间之间的范围；也可以是起始时间开始的一段持续时长范围。
在另一些实现方式中，该应用时间范围可以包括时隙位置或符号位置，用于指示中继设备在该时隙位置对应的时隙内或者该符号位置对应的符号内，应用该目标波束。
在另外一些实现方式中，该应用时间范围可以用于指示特定时隙中的特定符号范围。例如，该应用时间范围可以包括起始符号位置和终止符号位置，用于指示中继设备在特定时隙的起始符号位置和终止符号位置之间应用该目标波束。再例如，该应用时间范围可以包括起始符号位置和持续符号数目，用于指示中继设备在特定时隙的起始符号位置开始的持续符号数目内应用该目标波束。
需要说明的是，该特定时隙可以是网络设备指定的时隙，也可以是每个时隙。
波束应用时长信息二、应用所述目标波束的应用持续时长。
该应用持续时长可以是预设时间单位的倍数，该预设时间单位可以是毫秒、秒、时隙、符号或TDRA(Time Domain Resource Allocation，时域资源分配信息)。
波束应用时长信息三、应用目标波束的TDRA(Time Domain Resource Allocation，时域资源分配信息)索引值。
该TDRA索引值可以用于指示中继设备在特定时隙中应用目标波束的符号位置和持续时长(例如持续符号数目)，该特定时隙可以是网络设备指定的时隙，也可以是每个时隙；或者，该TDRA索引值可以用于指示中继设备应用目标波束的起始时间位置。
这样，中继设备可以通过上述波束时域信息中的一项或多项，确定目标波束的应用时间，并在该应用时间内应用该目标波束，从而可以灵活确定目标波束的时域信息(例如应用时间信息)，提高波束应用的效率。
在本公开的一些实施例中，该波束时域信息可以包括波束开始时刻信息和/或波束应用时长信息，中继设备基于该波束开始时刻信息和/或波束应用时长信息应用该波束的方式可以有多种，以下分别举例说明：
在一些实施例中，该目标波束可以以周期的方式进行应用，上述波束开始时刻信息可以包括特定时隙位置；该波束应用时长信息可以包括目标波束在一个时隙内的应用时间范围，该应用时间范围可以是特定符号位置，该特定符号位置可以包括一个或多个符号。示例地，一个时隙可以包含14个符号，该特定符号位置可以表征符号5，该特定符号位置也可以表征符号1至符号14之间的多个符号。
这样，中继设备可以在该特定时隙位置的特定符号位置，应用目标波束。该中继设备还可以根据波束周期信息，从该特定时隙位置开始周期性的在目标符号的特定符号位置应用该目标波束。
在一些实施例中，该目标波束可以以半静态的方式进行应用，上述波束开始时刻信息可以根据从网络设备接收到的MAC CE激活信令确定。中继设备可以将接收到网路设备发送的 MAC CE激活信令后的第M个时隙作为该目标波束的开始时刻，M可以为任意正整数，例如1或4。
例如，以波束应用时长信息中的特定符号位置为符号1至符号11，波束周期信息包括固定周期，该固定周期为5个时隙为例，若中继设备在时隙2接收到MAC CE激活信令，则可以将时隙6作为目标波束的开始时刻，中继设备可以在时隙6、时隙11、时隙16、时隙21、时隙26……的符号1至符号11之间应用该目标波束，直至接收到MAC CE去激活信令后，停止应用该目标波束。
在另一些实施例中，该目标波束可以以动态的方式进行应用，上述波束开始时刻信息可以包括特定时隙位置的特定符号位置，上述波束应用时长信息可以包括目标波束的应用持续时长(例如持续的时隙数目或符号数目)。
这样，中继设备可以在该特定时隙位置的特定符号位置，开始应用该目标波束，经过应用持续时长后停止应用该目标波束。
在一些实现方式中，上述波束开始时刻信息和波束应用时长信息均可以根据从网络设备接收到的DCI或者SCI确定。示例地，DCI或者SCI中可以指示中继设备在A个时隙后应用该目标波束，该DCI或者SCI中还可以包括SLIV(Start and Length Indicator，开始和长度指示)标识，通过该SLIV标识和特定SLIV表格确定上述特定符号位置和应用持续时长，该特定SLIV表格可以是中继设备从网络设备接收到的RRC信令中获取的参数，该SLIV表格包括SLIV标识和具体的SLIV内容的对应关系，该特定SLIV表格也可以是中继设备和网络设备预先约定好的表格，例如，可以是协议约定的表格。
例如，中继设备在时隙2接收到DCI或者SCI，该DCI或者SCI可以指示3个时隙后应用该目标波束，根据该DCI或者SCI中的SLIV标识确定的特定符号位置为第3个符号，应用持续时长(duration)为8个符号，则，中继设备可以在时隙5的第3-10个符号上应用该目标波束。
需要说明的是，上述以时隙和符号距离说明，上述时隙可以是一个较大的第一通信时间单元，上述符号可以是该第一通信时间单元划分后的较小的第二通信时间单元，例如，将第一通信时间单元划分为N个第二通信时间单元。
在另外一些实施例中，上述波束开始时刻信息可以包括用于指示应用该目标波束的绝对时刻信息，上述波束应用时长信息可以包括目标波束的应用持续时长(例如以毫秒或秒为单位的时间长度)。
在又一些实施例中，上述波束时域信息可以包括波束开始时刻信息，但未包括波束应用时长信息。这样，中继设备可以根据波束开始时刻持续应用该目标波束，直至接收到停止应用该目标波束的指示。该中继设备也可以使用预先设置的默认时长作为该目标波束的应用持续时长。
在又一些实施例中，在中继设备的当前时刻不是任何目标波束的应用时间的情况下，中继设备可以应用特定波束进行无线信号转发，该特定波束可以是最近一次使用的目标波束，也可以是预先设置的波束。
在又一些实施例中，在中继设备的当前时刻不是任何目标波束的应用时间的情况下，该中继设备可以关闭信号转发功能，不再转发任何无线信号。
这样，中继设备可以根据上述波束时域信息中的一项或多项，灵活地应用目标波束，以便进行无线信号转发。
图4是根据一示例性实施例示出的一种波束应用方法的流程图。如图4所示，该方法可以包括：
S401、中继设备确定目标波束。
示例地，中继设备可以响应于接收到网络设备发送的第一消息，确定目标波束。
S402、中继设备响应于接收到网络设备发送的第二消息，确定目标波束对应的波束时域信息。
在一些实施例中，该第二消息中可以包括目标波束对应的波束时域信息。这样，中继设备可以直接获取该波束时域信息，通过该波束时域信息可以确定开始应用该目标波束的第二时刻。
在另一些实施例中，可以将中继设备接收到所述第二消息的时刻与第一时长相加得到的第二时刻作为所述目标波束对应的波束开始时刻信息；然后，可以根据该波束开始时刻信息确定上述波束时域信息。其中，该第一时长可以是预先设置的时长或第二消息中携带的时长。
S403、中继设备在根据所述波束时域信息确定的应用时间内，应用所述目标波束。
在一些实施例中，在所述中继设备的当前时刻到达所述第二时刻的情况下，可以应用所述目标波束。
