下面结合附图,通过具体的实施例及其应用场景对本申请实施例提供的能量提供方法进行详细地说明。
图3示出本申请实施例中的能量提供方法的一种流程示意图,该方法300可以由第一设备执行。换言之,所述方法可以由安装在第一设备上的软件或硬件来执行。如图3所示,该方法可以包括以下步骤。
S310,第一设备按照第一目标传输模式的配置参数向第二设备发送信号,以通过所述信号向所述第二设备提供能量,其中,所述第一目标传输模式包括:第一目标周期,所述第一目标周期包括活动期和/或非活动期。
其中,在所述活动期,所述第一设备向所述第二设备发送信号,在所述非活动期,所述第一设备不向所述第二设备发送信号。
在本申请实施例中,第一设备可以配置有一种或多种传输模式,传输模式的配置参数中可以配置一个或多个周期,一个周期内可以只有活动期,也可以只有非活动期,也可以包含活动期和非活动期,第一设备可以在发送信号的过程选择第一目标周期。
在一个周期内包括活动期和非活动期的情况下,活动期和非活动期可以是连续的,也可以是离散的。例如,在一个周期内,可以将周期开始后的指定时长设置为活动期,而后续的时长为非活动期,或者,也可以将一个周期分为多个时间单元,分别设置每个时间单元是属于活动期还是非活动期,属于活动期或非活动期的时间单元可以不连续。
通过本申请实施例提供的技术方案,第一设备(即能量提供设备或供能设备)按照第一目标传输模式的配置参数,向第二设备(即能量接收设备, 如上述的反向散射设备)发送信号,以通过所述信号向第二设备提供能量,其中,所述第一目标传输模式包括第一目标周期,所述第一目标周期包括活动期和/或非活动期,第一设备在活动期向第二设备发送信号,而在非活动期不向所述第二设备发送信号,从而可以降低第一设备的功耗,延长第一设备向第二设备提供能量的时长。
在一个可能的实现方式中,第一目标传输模式的配置参数可以包括以下至少之一:
(1)第一周期以及所述第一周期对应的第一持续时间,其中,所述第一设备在所述第一周期的第一持续时间向所述第二设备发送信号。
即第一目标传输模式的配置参数中包括指示第一周期的长度以及第一周期内的持续时间的指示信息。其中,第一持续时间是指第一设备在第一持续时间内向第二设备发送信号。第一持续时间可以是第一周期中的活动期的一部分或全部。
可选的,所述第一持续时间至少大于第二设备所需的储能时间。该储能时间可以是第二设备通知给第一设备的,也可以是第三设备(例如,网络侧设备)通知给第一设备的,具体本申请实施例中不作限定。
(2)第二周期以及所述第二周期对应的第二持续时间,其中,所述第一设备在所述第二周期的第二持续时间向所述第二设备发送信号。
即第一目标传输模式的配置参数中包括指示第二周期的长度以及第二周期内的持续时间的指示信息。其中,第一设备在第二持续时间内向第二设备发送信号。
在本申请实施例中,第二周期的长度小于第一周期的长度。例如,第一周期的长度可以是第二周期的长度的m倍,其中,m为大于1的整数。
(3)第一定时器,其中,所述第一定时器在监听到所述第二设备发送的数据时启动,且在所述第一定时器超时前所述第一设备向所述第二设备发送信号。
即第一目标传输模式的配置参数中包括指示第一定时器的时长的指示信息。其中,第一定时器用于监听第二设备发送的数据,在监听到第二设备发送的数据时启动,在所述第一定时器的计时期间,第一设备向第二设备发送信号,即相当于延长了当前周期的持续时间(或活动期)。
(4)第二定时器,其中,所述第二定时器的时长为K个所述第二周期,其中,K为大于0的整数。
即第一目标传输模式的配置参数中包括指示第二定时器的时长的指示信息。其中,第二定时器用于计算K个第二周期,在第一目标周期为第二周期的情况下,在第二周期开始,第二定时器启动,如果从所述第二定时器启动到第二定时器超时前,第一定时器仍未启动,则可以将第一目标周期切换为第一周期。即如果从所述第二定时器启动到第二定时器超时前,第一定时器仍未启动,则说明第二设备当前可能处于不活跃状态,第一设备可以调长监控周期,以进一步节能。
在上述可能的实现方式,所述第一目标周期可以为所述第一周期,也可以为所述第二周期,而第一目标周期的非活动期为该周期中除活动期以外的其它时段。
可选地,在上述可能的实现方式中,第一目标传输模式的配置参数还可以包括:第一信号参数。其中,所述第一信号参数用于指示所述第一设备发送信号的能量、发射功率和波束方向中的至少一项。也就是说,第一目标传输的配置参数还可以包括与能量或功率相关的参数,例如发射功率,发射波束(beam)方向,或者与发射波束方向关联的其他参数等。
其中,所述第一信号参数可以属于第一目标传输模式的配置参数之一与其它参数一起被配置;或者可以与第一目标传输模式的其它参数独立,单独进行配置。例如,第一设备可以通过无线方式连接到基站,基站可以通过空口控制,分别配置第一目标传输模式的其它参数和所述第一信号参数。
在上述可能的实现方式中,第一设备在第一目标周期的活动期向第二设 备发送信号后,若在所述第一持续时间或所述第二持续时间内接收到所述第二设备发送的信号或者检测到所述第二设备发送的信号的能量,则启动所述第一定时器;所述第一定时器启动且没有超时,所述第一设备按照第一预设模式向所述第二设备发送信号;若在所述第一定时器超时前,接收到所述第二设备发送的信号,则重启所述第一定时器;若所述第一定时器超时,则按照第二预设模式向所述第二设备发送信号。通过该可能的实现方式,在接收到第二设备发送的信号或者检测到所述第二设备发送的信号的能量时,增长向第二设备发送信号的时间段,从而可以在第二设备有能量需求的时候,增加向第二设备提供能量的时长,以满足第二设备的需求。
在上述实现方式中,若第一持续时间或第二持续时间内没有接收第二设备发送的信号或者没有检测到所述第二设备发送的信号的能量,则在第一持续时间或第二持续时间之后,第一设备进入第一目标周期的非活动期,在第一目标周期结束后,第一设备又进入第一目标周期的第一持续时间或第二持续时间。
例如,第一设备可以先以第一目标周期为所述第二周期,在进入第二周期时,启动第二定时器,在所述第二周期的第二持续时间内向第二设备发送信号,如果在第二持续时间内,第一设备接收到第二设备发送的信号,例如,检测到能量超过门限的信号,或者解调到第二设备发送的信号,则第一设备启动第一定时器,在第一定时器超时前,按照第一预设模式向第二设备发送信号(相当于当前第一目标周期的活动期延长了),若在第一定时器超时前,又接收到第二设备发送的信号,则重启第二定时器,即再次延长第一目标周期的活动期。若在第一定时器超时,则第一设备按照第二预设模式向第二设备发送信号。若在第二持续时间内,第一设备未接收到第二设备发送的信号,则第一设备进行第二周期的非活动期,直到第二周期结束,第二设备进入下一个第二周期,在第二周期的第二持续时间内向第二设备发送信号,如此循环。
可选地,按照第一预设模式向第二设备发送信号可以包括:以第一时长为周期,向所述第二设备发送信号,其中,所述第一时长小于所述第一目标周期。即以比第一目标周期更小的周期向第二设备发送信号,以满足第二设备的能量需求。
或者,按照第一预设模式向第二设备发送信号也可以包括:连续向所述第二设备发送信号。即在第一定时器的计时范围内连续向第二设备发送信号,以满足第二设备的能量需求。
可选地,按照第二预设模式向所述第二设备发送信号可以包括:在所述第一定时器超时后,所述第一设备按照所述第二周期发送信号并启动所述第二定时器,若在所述第二定时器超时前所述第一定时器未启动,则所述第一设备按照所述第一周期发送信号。即第一定时器超时时,第二设备将第一目标周期切换为第二周期,若连续K个第二周期均未收到第二设备发送的信号,则第一设备将第一目标周期切换为第一周期,以第一周期向第二设备发送信号,以节约第一设备的功耗。
或者,按照第二预设模式向所述第二设备发送信号可以包括:不向所述第二设备发送信号,即第一设备处于非活动期。
在一个可能的实现方式中,可以配置多个传输模式,每个传输模式配置一套上述的配置参数,第二设备或第三设备可以通过信令,指示第一设备使用哪一个传输模式。因此,在该可能的实现方式中,在S310之前,该方法还可以包括:接收所述第二设备或第三设备发送的第一信令,其中,所述第一信令指示所述第一设备使用所述第一目标传输模式。其中,第三设备可以为网络侧设备,例如,基站,具体本申请实施例中不作限定。
在一个可能的实现方式中,第一目标传输模式的配置参数为预先配置和/或第三设备指示。例如,第一目标传输模式的配置参数可以预先为第一设备配置。或者,第一目标传输模式的配置参数也可以为第三设备指示。又或者,第一目标传输模式的配置参数可以部分为预先配置,部分为第三设备指示。 例如,第一目标传输模式的第一周期以及第一周期对应的第一持续时间、第二周期以及所述第二周期对应的第二持续时间、第一定时器以及第二定时器可以预先配置,而第一信号参数可以由第三设备指示。
在本申请实施例的另一个可能的实现方式中,第一目标传输模式的配置参数也可以采用另一套配置参数。在该可能的实现方式中,所述第一目标传输模式的配置参数包括:所述第一目标周期包括的时间单元的数量M,M为大于1的整数;M个所述时间单元中属于所述活动期的时间单元。也就是说,在该可能的实现方式中,一个第一目标周期中包括M个时间单元,第一目标传输模式的配置参数中包括第一目标周期中包括的时间单元的数量,以及M个时间单元中属于活动期的时间单元的指示信息,其中,所述指示信息可以直接指示哪些时间单元为活动期,也可以指示哪些时间单元为非活动期,具体本申请实施例中不作限定。
在上述可能的实现方式中,时间单元可以是预先定义的,例如,可以为一个或多个符号,或者,一个或多个时隙等,具体本申请实施例中不作限定。
在上述可能的实现方式中,第一目标传输模式的配置参数还可以包括:第二信号参数,其中,所述第二信号参数用于指示所述第一设备发送信号的能量、发射功率和波束方向中的至少一项。
即第一目标传输模式的配置参数中还可以包括与能量或功率相关的参数,例如发送信号的发射功率、发射beam方向等。其中,第二信号参数可以与第一目标传输模式的其他配置参数统一配置;或者,也可以与第一目标传输模式的其他配置参数相互独立,例如,第一设备可以通过无线方式连接到基站,基站可以通过空口分别配置第一目标传输模式的其他配置参数和第二信号参数。
在上述可能的实现方式中,可选地,采用上述配置参数的传输模式也可以配置多个,可以由专用信令指示第一设备所述第一目标传输模式。因此,在该可能的实现方式中,在第一设备按照所述第一目标传输模式的配置参数 向第二设备发送信号之前,该方法还可以包括:接收所述第二设备或第三设备发送的第二信令,其中,所述第二信令指示所述第一设备使用所述第一目标传输模式。其中,第三设备可以为基站等设备。在该可能的实现方式中,第二设备或第三设备可以通过第二信令指示第一设备所述第一目标传输模式。
其中,第二信令可以指示第一目标传输模式的各个配置参数,例如,第二信令中可以直接指示第一目标传输模式中的所述第一目标周期包含的时间单元的数量M,以及M个所述时间单元中属于活动期的时间单元。或者,也可以提前配置或约定多套传输模式以及各个传输模式对应的配置参数的值,第二信令中可以指示第一目标传输模式的标识。
可选地,也可以通过目标信号或目标信令激活一种传输模式。因此,在第一设备按照所述第一目标传输模式的配置参数向第二设备发送信号之前,该方法还可以包括:在接收到所述第二设备发送的目标信号或目标信令的情况下,激活或切换到所述第一目标传输模式。
例如,第一设备收到第二设备的某种目标信号或某种目标信令,从而激活或切换到第一目标传输模式,例如,收到第二设备在第一设备相同载频上的信号,又例如,通过能量检测(达到一个预设门限值)确定tag在发信号。其中,第一目标传输模式可以提前配置好的,或第一目标传输模式的模式是根据检测到的信号特征或模式而确定的。
可选地,第一目标传输模式的激活的时间可以是第一设备收到目标信号或目标信令后的第X个符号或时隙,其中,X为协议约定的或者网络配置的。
可选地,也可以根据第三定时器来切换传输模式。因此,在第一设备按照所述第一目标传输模式的配置参数向第二设备发送信号之前,该方法还可以包括:在进入第二目标传输模式时,启动第三定时器,在所述第三定时器超时前,未接收到所述第二设备发送的信号,切换到所述第一目标传输模式;其中,所述第一目标传输模式和所述第二目标传输模式的各个配置参数不完全相同。
在上述实现方式中,如在第三定时器超时前接收到所述第二设备发送的信号,则重启第三定时器,即第一设备继续保持在第二目标传输模式。
在上述实现方式中,由于第一设备是在第三定时器的计时期间未收到第二设备发送的信号才切换到第一目标传输模式的,因此,第一目标传输模式中的第一目标周期长度可以大于第二目标传输模式中的第二目标周期长度,以增大对第二设备发送信号的周期,进一步降低第一设备的功耗。当然,并不限于此,第一目标传输模式的第一目标周期也可以与第二目标传输模式的第二目标周期相同,但第一目标周期中的活动期所包含的时间单元比第二目标周期中的活动期所包含的时间单元少。
在上述实现方式中,第三定时器的长度可以根据实际应用确定,可以协议约定的,也可以是网络侧设备配置的,具体本申请实施例中不作限定。
在一个可能的实现方式中,第一设备还可以基于第二设备发送的供能请求,在第一目标传输模式下向第二设备发送信号。因此,在该可能的实现方式中,第一设备按照所述第一目标传输模式的配置参数向第二设备发送信号之前,所述方法还包括:接收所述第二设备发送的供能请求。第一设备在接收第二设备的供能请求后,可以在第一目标传输模式下向第二设备发送信号。
可选地,在上述可能的实现方式中,所述供能请求中还可以携带第二设备的请求的某些信息。可选的,所述供能请求中可以包括但不限于以下之一的信息:

(3)第三指示信息,其中,所述第三指示信息指示所述第一设备发送信号、以及发送信号的时域资源信息和发送信号的功率和/或波束方向;或者,所述第三指示信息指示所述第一设备不发送信号以及不发送信号的时间;即第三指示信息可以指示第一设备发送信号、发送信号的时域资源、以及发送信号的功率和/或波束方向,或者,指示第一设备在哪些时间段不发送信号。
(4)第四指示信息,其中,所述第四指示信息指示第一传输模式的配置参数。即第二设备在供能请求中携带期望的第一传输模式的配置参数。

在实际应用中,第二设备的周围可能存在多个供能设备,为了使接收到共供能请求的供能设备能够确定该供能请求的接收方,该供能请求中还可以携带第一设备的标识信息,例如,第一设备的编号等信息。
可选地,为了使第一设备获知第二设备的需求,供能请求中还可以包括以下至少之一:
(1)所述第二设备所需的储能时间。
(2)所述第二设备的储能接收功率。
(3)所述第二设备的通信接收功率。
在上述可能的实现方式中,在接收到第二设备发送的供能请求后,第一设备可以根据供能请求中携带的信息向第二设备发送供能请求。可选地,在接收所述第二设备发送的供能请求之后,所述方法还可以包括:
若所述第一设备能够满足所述供能请求所请求的第一传输模式,则以所述第一传输模式为所述第一目标传输模式;
若所述第一设备无法满足所述供能请求所请求的第一传输模式,则向所述第二设备发送非确认信息。
也就是说,在该可选的实现方式中,第一设备在接收到供能请求后,如果能够满足所请求的第一传输模式,则以第一传输模式为第一目标传输模式,向第二设备发送信号,如果无法满足第一传输模式,则向第二设备发送非确认信息(NACK)。
在第一设备无法满足第一设备所请求的第一传输模式的情况下,可选地,第二设备可以向所述第二设备发送第二传输模式的指示信息;若接收到所述第二设备返回的确认信息,则将所述第二传输模式作为所述第一目标传输模式;若接收到所述第二设备返回请求第三传输模式的供能请求,如果所述第一设备能够满足所述第三传输模式,则将所述第三传输模式作为所述第一目标传输模式;其中,所述第一传输模式、所述第二传输模式和所述第三传输模式的各个配置参数的值不完全相同,例如,第一传输模式、第二传输模式和第三传输模式中的部分配置参数的值不相同,或者,第一传输模式、第二传输模式和第三传输模式中的全部配置参数的值均不相同。
在本申请实施例中,第一设备向第二设备发送信号的发射功率可以是固定的,也可以是第二设备请求的,还可以是第一设备与第二设备协商的,也可以是第一设备自己调整的。
在一个可能的实现方式中,第一设备按照所述第一目标传输模式的配置参数向第二设备发送信号,包括以下之一:
(1)所述第一设备以固定的发射功率向所述第二设备发送信号。
第二设备在接收到第一设备的信号后,根据接收到的信号的强度,可以确定自己所需的储能时间,向第一设备发送供能请求,该供能请求中可以包括时域资源长度,请求第一设备在该时域资源长度内发送信号,以满足其储能需求。
(2)所述第一设备以固定的发射功率向所述第二设备发送信号,在接收到所述第二设备发送的供能请求后,按照所述供能请求中携带的第一功率调整步长,对所述固定的发射功率进行调整,以调整后的发射功率向所述第二设备发送信号。
T第二设备在接收到第一设备的信号后,根据接收到的信号的强度,可以确定自己所需的储能接收功率,向第一设备发送供能请求,该供能请求中可以包括时域资源长度以及第一设备发送信号的功率调整步长(例如,增加X dB,或者降低Y dB),请求第一设备在该时域资源长度内以功率调整步长对当前的发射功率进行设备后发送信号,以满足其储能需求。
(3)所述第一设备以所述第二设备请求的第一发射功率向所述第二设备发送信号,在接收到所述第二设备发送的第二功率调整步长后,按照所述第二功率调整步长对所述第一发射功率进行调整,以调整得到的第二发射功率向所述第二设备发送信号。
例如,第二设备向第一设备发送供能请求(例如1bit),第一设备收到第二设备的供能请求后按照第一功率发送信号;第二设备收到该信号后,向第一设备发送时域资源长度以及第一设备发送信号的功率调整步长,第一设备根据该功率调整步骤对当前的发射功率进行调整后,按照调整后的发射功率,在所述时域资源长度内发送信号。
(4)所述第一设备接收供能请求的信号质量以及所述供能请求的第三发 射功率,确定所述第一设备与第二设备之间的路径损耗,根据所述路径损耗以及所述第二设备期望接收的能量功率,确定第四发射功率,以所述第四发射功率向所述第二设备发送信号,其中,所述供能请求为所述第二设备发送的,所述供能请求中携带有所述第三发射功率和所述期望接收的能量功率。
例如,第二设备向第一设备发送供能请求,该供能请求中包括期望接收到的能量功率以及供能请求信号的发射功率;第一设备根据接收到的供能请求的RSRP以及供能请求的信号发射功率,确定第二设备和第一设备之间的路径损耗;第一设备根据上述路径损耗以及第二设备期望接收到的能量功率,确定自己的发射功率;第一设备按照该发射功率发送信号。通过该可能的实现方式,第一设备在发送信号时,可以考虑第一设备与第二设备之间的路径损耗,确定其发射功率,从而使得第二设备接收信号的功率能够满足其期望接收到的能量功率。
在另一个可能的实现方式中,第二设备也可以不参与发射功率的调整,第一设备通过轮询不同的发射功率,来确定发射功率。在该可能的实现方式中,第一设备按照所述第一目标传输模式的配置参数向第二设备发送信号,包括以下步骤:
步骤1,所述第一设备以第一发射功率发送信号。例如,第一设备以第一发射功率和第一波束方向发送信号。
步骤2,若在第一个时间窗内没有接收到所述第二设备发送的信号,则在第一个时间窗结束后,将所述第一发射功率抬升第一步长后得到第二发射功率,以所述第二发射功率发送信号。其中,第一步长和时间窗可以预先设置。
若在第一个时间窗内接收到第二设备发送的信号,则继续以第一发射功率发送信号。
步骤3,若在第二个时间窗内没有接收到所述第二设备发送的信号,则在第二个时间窗结束后,将所述第二发射功率抬升第一步长后得到第三发射 功率,以所述第三发射功率发送信号,直到在第n个时间窗内接收到所述第二设备发送的信号或者功率抬升的次数达到门限值,其中n为大于或等于1的整数。
例如,第一设备以第一发射功率和第一beam方向(可选)发送信号;如果第一设备在第一时间窗口内没有收到第二设备的信号(可以是基于门限的能量检测,或者解调到信息),则第一设备在第一时间窗口结束后将第一发射功率抬升第一步长(第一发射功率抬升第一步长,得到第二发射功率),第一设备以第二发射功率和第一beam方向(可选)发送信号;如果第一设备在第一时间窗口内收到第二设备的信号(可以是基于门限的能量检测,或者解调到信息),则第一设备继续以第一发射功率和第一beam方向(可选)发送信号。如果第一设备在第二时间窗口内没有收到第二设备的信号,则第一设备在第二时间窗口结束后将第二发射功率抬升第一步长(第二发射功率抬升第一步长,得到第三发射功率),第一设备以第三发射功率和第一beam方向(可选)发送信号;如果第一设备在第二时间窗口内收到第二设备的信号(可以是基于门限的能量检测,或者解调到信息),则第一设备继续以第二发射功率和第一beam方向(可选)发送信号。若功率抬升次数达到门限值,则第一设备以第一发射功率和第一beam方向(可选)发送信号。
在上述可能的实现方式中,在功率抬升的次数达到门限值后,所述第一设备以所述第一发射功率发送信号。
在一个可能的实现方式中,在上述过程中,如接收第二设备发送的信号,则启动激活期定时器,在所述激活期定时器超时前,以当前的发射功率发送信号;若在所述激活期定时器超时前,接收到所述第二设备发送的信号,则重启所述激活期定时器;若在所述激活期定时器超时前,未接收到所述第二设备发送的信号,则以当前的发射功率抬升所述第一步长后发送信号。
例如,如果第一设备在第一时间窗口内收到第二设备的信号,启动第一激活期定时器,激活期定时器到期前,第一设备以第一发射功率和第一beam 方向发送信号;如果第一设备在激活期定时器到期前收到第二设备的信号,则重启激活期定时器;如果第一设备在激活期定时器到期前没有收到第二设备的信号,则激活期定时器到期后,则第一设备以第二发射功率和第一beam方向(可选)发送信号。
如果第一设备在第二时间窗口内收到第二设备的信号,启动激活期定时器,激活期定时器到期前,第一设备以第二发射功率和第一beam方向发送信号;如果第一设备在激活期定时器到期前收到第二设备的信号,则重启激活期定时器;如果第一设备在激活期定时器到期前没有收到第二设备的信号,则激活期定时器到期后,则第一设备以第三发射功率和第一beam方向(可选)发送信号。
在一个可能的实现方式中,在上述实现方式中,在功率抬升的次数达到门限值后,还可以对波束方向进行调整。因此,该可能的实现方式中,第一设备按照所述第一目标传输模式的配置参数向第二设备发送信号,包括以下步骤:
步骤1,所述第一设备以第一发射功率和第一波束方向发送信号。
步骤2,若在第一时间窗内没有接收到所述第二设备发送的信号,则在第一时间窗结束后,将所述第一发射功率抬升第一步长后得到第二发射功率,以所述第二发射功率和所述第一波束方向发送信号;
步骤3,若在第二时间窗内没有接收到所述第二设备发送的信号,则在第二时间窗结束后,将所述第二发射功率抬升第一步长后得到第三发射功率,以所述第三发射功率和第一波束方向发送信号;
步骤4,若在功率抬升的次数达到门限值仍未接收到所述第二设备发送的信号,则所述第一发射功率和第二波束方向发送信号,若在接收下来的第一个时间窗内没有接收到所述第二设备发送的信号,则在第一个时间窗结束后,将所述第一发射功率抬升第一步长后得到第二发射功率,以所述第二发射功率和第二波束方向发送信号,直到在第n个时间窗内接收到所述第二设 备发送的信号或者功率抬升的次数达到门限值,其中n为大于或等于1的整数;
步骤5,若功率抬升的次数达到门限值仍未接收到所述第二设备发送的信号,则以第一发射功率和第三波束方向发送信号,如此反复,直到所有波束方向上的功率抬升次数均达到门限值。
通过上述可能的实现方式,第一设备可以以轮询不同的发射功率和波束方向的方式来确定供能的发射功率和波束方向,从而可以提高向第二设备供能的效果。
在上述实现方式中,可选地,所述方法还包括:若接收到所述第二设备发送的信号,则启动激活期定时器,在所述激活期定时器超时前,以当前的发射功率和波束方向发送信号;若在所述激活期定时器超时前,接收到所述第二设备发送的信号,则重启所述激活期定时器;若在所述激活期定时器超时前,未接收到所述第二设备发送的信号,则以当前的发射功率抬升所述第一步长后的功率和当前的波束方向发送信号。
在上述实现方式中,可选地,直到所有波束方向上的功率抬升次数均达到门限值后,所述第一设备以所述第一发射功率和所述第一波束方向发送信号。
在本申请实施例的上述各个可能的实现方式中,第二设备发送信号或接收信号所使用的能量可以是第一设备提供的能量,即第二设备收集第一设备发送的信号的能量,也可以是第二设备自身的储能设备的能量。例如,第二设备中有一个储能电池,因为其容量较小,因此只能供能给较少的能量以供第二设备的信号发送和信号接收,第二设备收发信号主要的能量供应来自于外部的供能设备即第二设备。
在本申请实施例中,第一设备可以是手机等信号源,第一设备可以与多个第二设备关联,即为多个第二设备供能,第一设备针对每个第二设备各维持一套传输模式,第一设备在每个时刻根据多套传输模式叠加的效果来确定 最终使用的传输模式和/或最终使用的发射功率。
