再例如,第二通信模式可以包括网络设备为终端设备配置的第三时间长度与第四时间长度,并指示第三时间长度、第四时间长度是交替出现的。
当第三时间长度与第四时间长度周期性出现时,则对于每一个周期中的第三时间长度,终端设备与网络设备之间可以进行数据传输,此外,对于每一个周期中的第四时间长度,终端设备可以进行能量收集,中止与终端设备之间进行数据传输。
可选地,作为一种实现方式,上述第三时间长度与第四时间长度可以是网络设备根据当前网络的实际情况为终端设备配置的。
例如,网络设备可以根据当前服务的终端设备的数量,确定自己无法支持终端设备期望的进行数据传输的时间长度,在这种情况下,网络设备为终端设备配置的进行数据传输的时间长度可以与终端设备期望的进行数据传输的时间长度不同,即第三时间长度与第一时间长度不同,或者,网络设备为终端设备配置的中断数据传输的时间长度可以与终端设备期望的中断数据传输的时间长度不同,即第四时间长度与第二时间长度不同。
可选的,作为一种实现方式,第三时间长度与第一时间长度可以相同,换句话说,网络设备为终端设备配置的进行数据传输的时间长度与终端设备期望的进行数据传输的时间长度相同。
可选的,作为一种实现方式,第二时间长度与第四时间长度可以相同,换句话说,网络设备为终端设备配置的中断数据传输的时间长度与终端设备期望的中断数据传输的时间长度相同。
可选的,作为一种实现方式,在第三时间长度与第一时间长度相同,且第二时间长度与第四时间长度相同的情况下,网络设备可以无需向终端设备发送第一配置信息,而向终端设备发送确认信息,确认信息代表网络设备同意终端设备期望的第一时间长度与第二时间长度,之后,终端设备与网络设备之间在第一时间长度内进行数据传输,在第二时间长度内中断进行数据传输。
可选的,作为一种实现方式,第一配置信息可以承载在网络设备向终端设备发送的RRC重配消息中。
可选的,作为一种实现方式,终端设备可以向网络设备上报自己是第一类型的终端设备,或者,向网络设备上报自己的数据传输的特征是时断时续的,在这种情况下,方法200还可以包括步骤201:终端设备向网络设备发送第二指示信息,第二指示信息指示终端设备为第一类型的终端设备或终端设备的数据传输的特征是时断时续的。相应地,网络设备接收来自终端设备的第二指示信息。
网络设备根据第二指示信息,确定终端设备为第一类型的终端设备,或者,确定终端设备的数据传输的特征是时断时续的,之后,网络设备在接收到来自终端设备的第一指示信息后,通过第一配置信息为终端设备配置第三时间长度与第四时间长度。
可选的,作为一种实现方式,第二指示信息可以承载在非接入层的终端设备能力信息消息中或终端设备辅助信息消息中。
可选的,第二指示信息与第一指示信息可以承载在同一消息(或信令)中,一起发送给网络设备。或者,第二指示信息与第一指示信息也可以承载在不同消息中,分别发送给网络设备。
可选的,作为一种实现方式,当终端设备在第三时间长度内与网络设备之间进行数据传输时,如果终端设备发现当前实际支持的用于数据传输的时间长度小于第三时间长度,终端设备可以向网络设备上报终端设备当前实际支持的用于数据传输的时间长度中的剩余时间长度,或者,向网络设备上报当前实际支持的用于数据传输的时间长度小于第三时间长度,在这种情况下,方法200还可以包括步骤204:终端设备向网络设备发送第三指示信息,第三指示信息指示终端设备当前实际支持的用于数据传输的时间长度中的剩余时间长度,或者,终端设备当前实际支持的用于数据传输的时间长度小于第三时间长度。
例如,假设终端设备在与网络设备之间进行数据传输的过程中,发现当前实际支持的用于数据传输的时间长度小于第三时间长度,在这种情况下,终端设备可以通过第三指示信息向网络设备上报当前实际支持的用于数据传输的时间长度中的剩余时间长度,或者,终端设备可以通过第三指示信息向网络设备上报当前实际支持的用于数据传输的时间长度小于第三时间长度。
例如,第三时间长度为10毫秒,假设终端设备与网络设备之间的数据传输进行到第4毫秒的时候,终端设备发现剩余的可用于数据传输的时间长度为4毫秒,可以看出,终端设备当前实际支持的用于数据传输的时间长度为8毫秒,小于第三时间长度10毫秒,在这种情况下,终端设备可以通过第三指示信息向网络设备上报当前实际支持的用于数据传输的时间长度中的剩余时间长度,即,4毫秒,或者,终端设备可以通过第三指示信息向网络设备上报当前实际支持的用于数据传输的时间长度小于第三时间长度。
之后,终端设备在自己当前实际支持的用于数据传输的时间长度结束之前中止向网络设备发送上行数据,此外,网络设备根据来自终端设备的第三指示信息,在终端设备当前实际支持的用于数据传输的时间长度结束之前中止向终端设备发送下行数据。
可选的,作为一种实现方式,当终端设备当前实际支持的用于数据传输的时间长度小于第三时间长度时,当前实际支持的用于数据传输的时间长度相对于第三时间长度所减少的时间长度可以是协议预定义的或者是网络设备预先配置的。
终端设备当前实际支持的用于数据传输的时间长度相对于第三时间长度所减少的时间长度可以理解为:第三时间长度与终端设备当前实际支持的用于数据传输的时间长度之 间的差值,例如,第三时间长度为12毫秒,当前实际支持的用于数据传输的时间长度为8毫秒,则终端设备当前实际支持的用于数据传输的时间长度相对于第三时间长度所减少的时间长度为4毫秒。
可选的,作为一种实现方式,终端设备除了向网络设备上报第一时间长度与第二时间长度,还可以向网络设备上报终端设备期望在第一时间长度内支持的上行传输的次数和/或下行传输的次数,在这种情况下,方法200还可以包括步骤205:终端设备向网络设备发送第四指示信息,第四指示信息指示终端设备期望在第一时间长度内支持的上行传输的次数和/或下行传输的次数。值得一提的是,网络设备在接收到第四指示信息后,可以向终端设备发送网络设备配置的终端设备在第三时间长度内支持的上行传输的次数和/或下行传输的次数,例如,网络设备可以向终端设备再次发送第一配置信息,以向终端设备指示网络设备配置的终端设备在第三时间长度内支持的上行传输的次数和/或下行传输的次数。值得一提的是,在本申请实施例中,可以将用于指示第一通信模式的信息与用于指示网络设备配置的终端设备在第三时间长度内支持的上行传输的次数和/或下行传输的次数的信息都称为第一配置信息。
例如,网络设备通过再次发送的第一配置信息配置终端设备在第三时间长度内支持8次上行传输与6次下行传输,则后续终端设备可以在第三时间长度内进行8次上行传输,在8次上行传输完成后中止向网络设备发送上行数据,并且网络设备可以在第三时间长度内可以进行6次下行传输,在6次下行传输完成后中止向终端设备发送下行数据。
可选的,作为一种实现方式,终端设备可以既向网络设备上报第三指示信息,又上报第四指示信息。
例如,网络设备通过第一配置信息配置的第三时间长度为10毫秒,并且在接收到第四指示信息后,通过再次发送的第一配置信息配置终端设备在第三时间长度内支持7次上行传输与5次下行传输,然而,终端设备在与网络设备之间进行数据传输的过程中,发现当前实际支持的用于数据传输的时间长度为8秒,在这种情况下,终端设备可以通过第三指示信息向网络设备上报当前实际支持的用于数据传输的时间长度中的剩余时间长度,或者,终端设备可以通过第三指示信息向网络设备上报当前实际支持的用于数据传输的时间长度小于第三时间长度。
假设完成上述7次上行传输与5次下行传输共需要9毫秒,在这种情况下,终端设备与网络设备之间可以在终端设备当前实际支持的用于数据传输的时间长度结束之前中断进行数据传输,换句话说,在这种情况下,终端设备与网络设备之间实际完成的数据传输的次数小于12。
值得一提的是,在具体实现时,上述两个第一配置信息可以承载在同一消息中或承载在不同消息中,例如,在一种实现方式中,网络设备可以在接收到来自终端设备的第一指示信息后,通过一条消息向终端设备发送用于指示第一通信模式的第一配置信息,在接收到来自终端设备的第四指示信息后,通过另一条消息向终端设备发送用于指示网络设备配置的终端设备在第三时间长度内支持的上行传输的次数和/或下行传输的次数的第一配置信息;在另一种实现方式中,网络设备可以在接收到来自终端设备的第一指示信息与第四指示信息后,通过一条消息向终端设备发送上述两个第一配置信息,本申请实施例对此不作限定。
可选的,作为一种实现方式,第三指示信息与第四指示信息可以承载在同一消息中,例如,第三指示信息与第四指示信息可以承载在非接入层的终端设备能力信息消息中或终端设备辅助信息消息中。或者,第三指示信息与第四指示信息可以承载在不同消息中,分别发送给网络设备,本申请对终端设备发送第三指示信息和第四指示信息的先后顺序,即步骤204和步骤205的先后顺序不做限制。
可选的,作为一种实现方式,网络设备配置的终端设备在第三时间长度内支持的上行传输的次数和/或下行传输的次数与终端设备期望在第一时间长度内支持的上行传输的次数和/或下行传输的次数可以相同,在这种情况下,网络设备可以无需向终端设备发送第一配置信息,而向终端设备发送确认信息,确认信息代表网络设备同意终端设备期望的第在第一时间长度内支持的上行传输的次数和/或下行传输的次数。
可选的,作为一种实现方式,如果网络设备既同意终端设备期望的第一时间长度与第二时间长度,又同意终端设备期望的在第一时间长度内支持的上行传输的次数和/或下行传输的次数,网络设备可以向终端设备发送两个确认信息,这两个确认信息中的一个代表网络设备同意终端设备期望的第一时间长度与第二时间长度,另一个代表同意终端设备期望的在第一时间长度内支持的上行传输的次数和/或下行传输的次数,可选的,这两个确认信息可以携带在同一消息中,也可以携带在不同消息中;或者,网络设备可以向终端设备发送一个确认信息,该确认信息代表网络设备既同意终端设备期望的第一时间长度与第二时间长度,又同意终端设备期望的第在第一时间长度内支持的上行传输的次数和/或下行传输的次数。
基于上述技术方案,通过使终端设备与网络设备针对终端设备进行数据传输的时间长度以及进行能量收集的时间长度达成一致,终端设备与网络设备之间仅在进行数据传输的时间长度内进行数据传输,在进行能量收集的时间长度内中断进行数据传输,从而降低由于网络设备对终端设备进行数据传输的时间长度、中断数据传输的时间长度的判断与实际情况不一致,导致网络设备与终端设备之间传输的数据丢失的概率。
需要说明的是,上述仅以终端设备与网络设备之间处于RRC连接态为例,对方法200作了介绍,这并不构成对本申请实施例的限定,在具体实现时,方法200还可以应用在小包传输场景中。
与终端设备与网络设备之间处于RRC连接态不同的是:在小包传输场景中,第一配置信息可以承载在RRC释放消息中,例如,如果终端设备在与网络设备之间建立了RRC连接后的一段时间内没有进行数据传输,网络设备可以通过RRC释放消息将终端设备释放到RRC非活跃(inactive)态,在这种情况下,第一配置信息可以携带在RRC释放消息中发送至终端设备,以使当终端设备在RRC非活跃态下进行小包传输时,可以在第三时间长度内与网络设备之间进行数据传输。
此外,在小包传输场景中,上述的第一通信模式还可以包括网络设备与终端设备之间处于小包传输过程中的一段时间长度以及终端设备期望进行数据传输的时间长度,网络设备可以据此计算出终端设备期望的中断数据传输的时间长度,例如,网络设备可以将网络设备与终端设备之间处于小包传输过程中的一段时间长度中,除去终端设备期望进行数据传输的时间长度以外的时间长度,确定为终端设备期望的中断数据传输的时间长度,或者,第一通信模式还可以包括网络设备与终端设备之间处于小包传输过程中的一段时间长度 以及终端设备期望中断数据传输的时间长度,网络设备可以据此计算出终端设备期望进行数据传输的时间长度,例如,网络设备可以将网络设备与终端设备之间处于小包传输过程中的一段时间长度中,除去终端设备期望的中断数据传输的时间长度以外的时间长度,确定为终端设备期望进行数据传输的时间长度,或者,第一通信模式还可以包括终端设备在小包传输过程中期望的进行数据传输的时间长度以及期望的中断数据传输的时间长度。
进一步地,在小包传输场景中,第一通信模式还可以用于确定终端设备在小包传输过程中期望的进行数据传输的时间长度以及期望的中断数据传输的时间长度是周期性出现的。
在小包传输场景中,第二通信模式还可以包括网络设备与终端设备之间处于小包传输过程中的一段时间长度与网络设备为终端设备配置的进行数据传输的时间长度,终端设备可以据此计算出网络设备为终端设备配置的中断数据传输的时间长度,例如,终端设备可以将网络设备与终端设备之间处于小包传输过程中的一段时间长度中,除去网络设备为终端设备配置的进行数据传输的时间长度以外的时间长度,确定为网络设备为终端设备配置的中断数据传输的时间长度,或者,第二通信模式还可以包括网络设备与终端设备之间处于小包传输过程中的一段时间长度以及网络设备为终端设备配置的中断数据传输的时间长度,例如,终端设备可以将网络设备与终端设备之间处于小包传输过程中的一段时间长度中,除去网络设备为终端设备配置的中断数据传输的时间长度以外的时间长度,确定为网络设备为终端设备配置的进行数据传输的时间长度,或者,第二通信模式还可以包括网络设备在小包传输过程中为终端设备配置的进行数据传输的时间长度与网络设备为终端设备配置的中断数据传输的时间长度。
进一步地,在小包传输场景中,第二通信模式还可以用于确定网络设备在小包传输过程中为终端设备配置的进行数据传输的时间长度以及中断数据传输的时间长度是周期性出现的。

可选的,作为一种实现方式,在与网络设备建立RRC连接的过程中,终端设备可以通过随机接入过程中的消息1(message 1,msg1)指示第二指示信息,例如,通过消息1的特定的前导码(preamble)或特定的物理随机接入信道(physical random access channel,PRACH)资源指示第二指示信息。
可选的,作为一种实现方式,在与网络设备建立RRC连接的过程中,终端设备可以通过随机接入过程中的消息3(message 3,msg3)指示第二指示信息,例如,终端设备可以在消息3中承载第二指示信息、并发送承载有第二指示信息的消息3。
