Description

一种数据传输、确定发送功率的方法及设备
本申请要求在2018年11月1日提交中国专利局、申请号为201811295285.0、申请名称为“一种数据传输、确定发送功率的方法及设备”的中国专利申请的优先权,其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信技术领域,尤其涉及一种数据传输、确定发送功率的方法及设备。
背景技术
近年来,以车联网为代表的智能交通技术得到了飞速的发展。在第三代合作伙伴计划(3rd generation partnership project,3GPP)也进行了类似的研究,产生了车到一切(vehicle-to-everything,V2X)技术。其中,V2X技术例如包括车辆到车辆(vehicle-to-vehicle,V2V)通信技术,车辆到人(vehicle-to-pedestrian,V2P)通信技术,车辆到道路设施(vehicle-to-infrastructure,V2I)通信技术等,当然还可能包括其他的通信技术。例如,在3GPP的长期演进(long term evolution,LTE)系统中,已经完成了对版本(Rel)-14的标准化研究,并且正在进行Rel-15的标准化工作。并且,部分场景,如高通公司已经宣布发布了基于Rel-14协议的车联网芯片,并在与整车联厂商积极开始实用化的测试工作。
而另一方面,3GPP基于对第五代移动通信技术(5th generation,5G)展开研究的标准已经发布,在5G新无线(new radio,NR)的新技术框架下进行车联网技术的增强研究也被提上日程。那么,如何有效地实现在5G技术框架下现有的基于LTE的Rel-14和Rel-15的V2X技术与新的NR研究出的V2X技术的共存,特别地实现这两种制式的V2X技术在同一个终端设备中的共存,是亟待解决的问题。
发明内容
本申请实施例提供一种数据传输、确定发送功率的方法及设备,用于实现基于LTE的V2X技术和基于NR的V2X技术在同一个终端设备中的共存。
第一方面,提供第一种数据传输方法,该方法包括:第一终端设备获取第一时域资源,所述第一时域资源用于采用第一侧行传输技术传输信息;所述第一终端设备获取第二时域资源,所述第一时域资源包括所述第二时域资源,所述第二时域资源用于采用第二侧行传输技术传输信息,所述第一侧行传输技术与所述第二侧行传输技术为不同的传输技术;所述第一终端设备在所述第二时域资源上采用所述第二侧行传输技术发送或接收第一信息。
该方法可由第一通信装置执行,第一通信装置可以是终端设备或能够支持终端设备实现该方法所需的功能的通信装置,当然还可以是其他通信装置,例如芯片系统。这里以第一通信装置是第一终端设备为例。
例如第一侧行传输技术是基于LTE的V2X技术,第二侧行传输技术是基于NR的侧行传输技术,可以看到,本申请实施例提供的技术方案实现了这两种技术在第一终端设备内的共存。在本申请实施例中,第一终端设备获取的第二时域资源属于第一时域资源,也 就是第一时域资源包括第二时域资源,而第一时域资源是用于采用第一侧行传输技术传输信息的资源,第二时域资源是用于采用第二侧行传输技术传输信息的资源,相当于终端设备在利用第二侧行传输技术传输信息时,可以利用原本分配给第一侧行传输技术的资源,例如,采用第二侧行传输技术所传输的信息可能对时延的要求较高,使得在采用第二侧行传输技术传输信息时可以占用分配给第一侧行传输技术的资源,有助于尽量满足采用第二侧行传输技术所传输的信息对时延的要求。
结合第一方面,在第一方面的一种可能的设计中,所述第一终端设备获取第二时域资源包括:所述第一终端设备接收来自网络设备的第一指示信息,所述第一指示信息用于指示所述第二时域资源;或,所述第一终端设备根据所述第一时域资源确定所述第二时域资源。
第一终端设备可以根据网络设备的指示获取第二时域资源,或者也可以自行根据第一时域资源确定第二时域资源,较为灵活。
结合第一方面,在第一方面的一种可能的设计中,所述方法还包括:所述第一终端设备在所述第二时域资源和第三时域资源上采用所述第二侧行传输技术发送或接收所述第一信息,所述第三时域资源用于采用所述第二侧行传输技术传输信息。
例如一种情况为,第一信息对于时延的要求较高,或者较为重要或紧急,则第一终端设备可以只是在第二时域资源上采用第二侧行传输技术发送或接收第一信息,而无需再分配给第二侧行传输技术的资源上也采用第二侧行传输技术一并发送或接收第一信息,也就是,第一信息的传输可能只需用到第二时域资源。或者,另一种情况为,第一信息的数据量较大,则第一终端设备除了在第二时域资源上采用第二侧行传输技术发送或接收第一信息之外,还可以在第三时域资源上采用第二传输技术发送或接收第一信息,也就是说,第一终端设备在第二时域资源和第三时域资源上采用第二侧行传输技术发送或接收第一信息,则第二终端设备在第二时域资源和第三时域资源上采用第二侧行传输技术相应接收或发送第一信息,从而保证第一信息能够得到完整传输。第三时域资源就可以是用于采用第二侧行传输技术传输信息的资源。
结合第一方面,在第一方面的一种可能的设计中,所述方法还包括:所述第一终端设备发送第二指示信息,所述第二指示信息用于指示所述第二时域资源。
因为第一终端设备要在第二时域资源上通过第二链路发送或接收数据,则第一终端设备在确定第二时域资源后,可以将第二时域资源的信息指示给第二终端设备,以使得第二终端设备能够在第二时域资源上进行相应的接收或发送操作。
结合第一方面,在第一方面的一种可能的设计中,用于发送所述第二指示信息的时域位置与所述第二时域资源所在的时域位置之间的间隔大于或等于预定间隔。
预定间隔例如是网络设备通过信令指示的,或者是通过协议预定义的,或者也可以是为终端设备预配置的。预定间隔可以大于0,相当于第二指示信息和第二时域资源之间有一定的时间间隔,以便第二终端设备接收第二指示信息后能有较为充足的响应时间,从而能够在第二时域资源上进行及时地接收或发送,或者预定间隔也可以是0,也就是,发送第二指示信息的时域位置和第二时域资源所在的时域位置可以是相邻的。
结合第一方面,在第一方面的一种可能的设计中,所述第二指示信息用于指示所述第二时域资源所在的时间窗的信息,或所述第二指示信息用于指示所述第二时域资源的时域起始位置和持续时长,或所述第二指示信息用于指示所述第二时域资源的时域结束位置和 持续时长,或所述第二指示信息用于指示所述第二时域资源的时域起始位置和时域结束位置。
对于第二指示信息具体的指示方式,本申请实施例不做限制。
结合第一方面,在第一方面的一种可能的设计中,所述方法还包括:当满足第一条件,且所述第一终端设备在所述第二时域资源上通过第一链路做接收检测时,停止做所述接收检测;和/或,当满足第一条件,且所述第一终端设备在所述第二时域资源上有通过第一链路待发送的第一数据时,停止在所述第二时域资源发送所述第一数据,或将所述第一数据的发送功率从第一发送功率调整为第二发送功率,并通过所述第二发送功率在所述第二时域资源上发送所述第一数据;其中,所述第一链路用于采用所述第一侧行传输技术传输信息。
如果在第二时域资源上本身要通过第一链路传输数据,那么可以暂停在第一链路上的传输,或者可以降低在第一链路上的发送功率,从而可以保证第二时域资源能够用于第二链路的传输。
结合第一方面,在第一方面的一种可能的设计中,所述第一条件包括以下至少一项:所述第一终端设备通过第二链路传输的数据的优先级高于所述第一终端设备通过所述第一链路传输的数据的优先级,所述第二链路用于采用所述第二侧行传输技术传输信息;所述第一终端设备通过所述第一链路传输的数据的优先级低于第一预定优先级;所述第一终端设备通过所述第二链路传输的数据的传输时延小于预定时延,且所述终端设备通过所述第二链路传输的数据的优先级高于第二预定优先级;所述第一终端设备通过所述第二链路传输的数据的传输距离小于预定距离,且所述第一终端设备通过所述第二传输的数据的优先级高于第二预定优先级;所述第一终端设备通过所述第二链路传输的数据的数据包大小小于预定值,且所述第一终端设备通过所述第二链路传输的数据的优先级高于第二预定优先级;或,所述第一终端设备通过所述第二链路传输的数据的发送功率小于预定发送功率,且所述第一终端设备通过所述第二链路传输的数据的优先级高于第二预定优先级。
为了使得第二链路对于第一链路的资源的抢占更有意义,在本申请实施例中,第二链路要抢占第一链路的资源,可以是在第二链路满足第一条件的情况下,或者说是在第二链路的数据满足第一条件的情况下,如果第二链路满足第一条件,则可以表明第二链路的数据的优先级较高,或者可以表明第二链路的数据较为紧急或较为重要等,在这种情况下,可以使得第二链路占用第一链路的第二时域资源,从而保证第二链路的数据能够得到及时发送。
结合第一方面,在第一方面的一种可能的设计中,所述第一时域资源包括所述第二时域资源,包括:所述第二时域资源属于所述第一终端设备在所述第一时域资源中在第一链路做测量操作之外的子帧;和/或,所述第二时域资源属于所述第一时域资源中所述第一终端设备的第一链路不发送数据的子帧;其中,所述第一链路用于采用所述第一侧行传输技术传输信息。
例如,第一时域资源中包括分配给多个终端设备的第一链路的时域资源,第一终端设备的第一链路可能只利用第一时域资源中的部分时域资源,则第一终端设备的第二链路可以占用第一时域资源中未被第一终端设备的第一链路占用的时域资源来发送或接收数据,从而可以尽量提高对第一时域资源的利用率。
结合第一方面,在第一方面的一种可能的设计中,分配给第一链路的资源和分配给第 二链路的资源位于同一载波上,或位于不同的载波上,所述第一链路用于采用所述第一侧行传输技术传输信息,所述第二链路用于采用所述第二侧行传输技术传输信息。

例如第一终端设备可以确定分配给第一链路的发送资源,和/或,分配给第一链路的接收资源。第一终端设备确定的第二时域资源就可以属于分配给第一链路的发送资源或接收资源,从而第一终端设备可以明确第二时域资源是发送资源还是接收资源。

如果网络设备为第一链路和第二链路分配了公共资源,也就是确定了同时分配给第一链路和第一终端设备的用于第二链路的发送资源,和/或,同时分配给第一链路和第一终端设备的用于第二链路的接收资源,那么网络设备还可以为第一终端设备分配仅用于第二链路的资源,以供终端设备更好地传输第二链路的数据。
结合第一方面,在第一方面的一种可能的设计中,所述方法还包括:所述第一终端设备发送第三指示信息,所述第三指示信息用于指示所述第一时域资源中包括的用于所述第一链路的发送资源和/或接收资源。

结合第一方面,在第一方面的一种可能的设计中,所述第一链路的候选同步源的类型和所述第二链路的候选同步源的类型不同时,所述第一终端设备确定其中优先级较高的候选同步源作为所述第一链路和所述第二链路的同步源;或,当所述第一链路的候选同步源 的类型和所述第二链路的候选同步源的类型不同时,所述第一终端设备确定所述第一链路的同步源为所述第二链路的同步源;或,根据所述第一链路的定时获取所述第二链路的定时。

接下来结合附图介绍本申请实施例提供的技术方案。
本申请实施例提供一种数据传输方法,请参见图3,为该方法的流程图。在下文的介绍过程中,以该方法应用于图1所示的网络架构为例。另外,该方法可由三个通信装置执行,这三个通信装置例如为第一通信装置、第二通信装置和第三通信装置,其中,第一通信装置可以是网络设备或能够支持网络设备实现该方法所需的功能的通信装置,或者第一通信装置可以是终端设备或能够支持终端设备实现该方法所需的功能的通信装置,当然还可以是其他通信装置,例如芯片系统。第二通信装置可以是网络设备或能够支持网络设备实现该方法所需的功能的通信装置,或者第二通信装置可以是终端设备或能够支持终端设备实现该方法所需的功能的通信装置,当然还可以是其他通信装置,例如芯片系统。对于第三通信装置也是同样,第三通信装置可以是网络设备或能够支持网络设备实现该方法所需的功能的通信装置,或者第三通信装置可以是终端设备或能够支持终端设备实现该方法所需的功能的通信装置,当然还可以是其他通信装置,例如芯片系统。且对于第一通信装置、第二通信装置和第三通信装置的实现方式均不做限制,例如第一通信装置可以是网络设备,第二通信装置是终端设备,第三通信装置也是终端设备,或者第一通信装置是网络设备,第二通信装置是能够支持终端设备实现该方法所需的功能的通信装置,第三通信装置是终端设备,或者第一通信装置是网络设备,第二通信装置和第三通信装置均是能够支持终端设备实现该方法所需的功能的通信装置,等等。其中,网络设备例如为基站。
为了便于介绍,在下文中,以该方法由网络设备和终端设备执行为例,也就是,以第一通信装置是网络设备、第二通信装置和第三通信装置均是终端设备为例。因为本实施例是以应用在图1所示的网络架构为例,因此,下文中所述的网络设备可以是图1所示的网络架构中的网络设备,下文中所述的第一终端设备可以是图1所示的网络架构中的终端设备1,下文中所述的第二终端设备可以是图1所示的网络架构中的终端设备2。
S31、第一终端设备获取第一时域资源,所述第一时域资源用于采用第一侧行传输技术传输信息;
S32、第一终端设备获取第二时域资源,所述第一时域资源包括所述第二时域资源,所述第二时域资源用于采用第二侧行传输技术传输信息,所述第一侧行传输技术与所述第二侧行传输技术为不同的传输技术;
S33、所述第一终端设备在所述第二时域资源上采用所述第二侧行传输技术发送或接收第一信息,第二终端设备在所述第二时域资源上采用所述第二侧行传输技术相应接收或发送所述第一信息。
在本申请实施例中,第一时域资源用于采用第一侧行传输技术传输信息,第二时域资源用于采用第二侧行传输技术传输信息,可见对于第一终端设备来说,既可以采用第一侧行传输技术传输信息,也可以采用第二侧行传输技术传输信息,实现了两种侧行传输技术在一个终端设备中的共存。例如第一侧行传输技术为基于LTE的V2X技术(也可以描述为LTE-V2X),第二侧行传输技术为基于NR的V2X技术(也可以描述为NR-V2X),那么本申请实施例也就是实现了基于LTE的V2X技术和基于NR的V2X技术在一个终端设 备中的共存。当然第一侧行传输技术和/或第二侧行传输技术还可能是其他的技术,本申请实施例对此并不限制。
当然,第一终端设备在第二时域资源上可以采用单播方式,利用第二侧行传输技术向第二终端设备发送第一信息,则第二终端设备在第二时域资源上采用第二侧行传输技术相应接收来自第一终端设备的第一信息,或者第一终端设备在第二时域资源上可以采用单播方式,利用第二侧行传输技术接收来自第二终端设备的第一信息,则第二终端设备在第二时域资源上采用第二侧行传输技术向第一终端设备发送第一信息;或者,第一终端设备在第二时域资源上也可以采用组播或广播方式利用第二侧行传输技术发送第一信息,则可能有多个终端设备能够在第二时域资源上利用第二侧行传输技术接收来自第一终端设备的第一信息,第二终端设备可以是多个终端设备中的一个,第二终端设备也就能够在第二时域资源上利用第二侧行传输技术接收来自第一终端设备的第一信息,或者,第二终端设备在第二时域资源上也可以采用组播或广播方式利用第二侧行传输技术发送第一信息,则可能有多个终端设备能够在第二时域资源上利用第二侧行传输技术接收来自第二终端设备的第一信息,第一终端设备可以是多个终端设备中的一个,第一终端设备也就能够在第二时域资源上利用第二侧行传输技术接收来自第二终端设备的第一信息。
在本申请实施例中还涉及到两个概念,终端设备的第一链路和第二链路,第一链路用于通过第一侧行传输技术传输信息,第二链路用于通过第二侧行传输技术传输信息,也就是说,第一链路和第二链路都是sidelink链路。例如,第一侧行传输技术为基于LTE的V2X技术,即以LTE技术作为底层技术来实现V2X通信的技术,第二侧行传输技术为基于NR的V2X技术,即以NR技术作为底层技术来实现V2X通信的技术,则第一链路可以是基于LTE的V2X链路,第二链路可以是基于NR的V2X链路。其中,第一链路和第二链路是相互同步的,这里的链路同步可以理解为,是链路的时间单元之间的同步,也就是说,第一链路的时间单元和第二链路的时间单元是同步的,从而可以实现第二链路的数据占用第一链路的时域资源。要实现第一链路和第二链路的同步,例如可以通过第一链路的同步源的类型和第二链路的同步源的类型相同的方式实现,或可以通过第一链路和第二链路具有预设的定时偏差的方式实现。该定时偏差例如为网络设备通过信令指示给第一终端设备的,或者是协议预定义的,或者也可以是预配置给第一终端设备的。例如,一种定时偏差是1ms的整数倍,或者也可以是一个子帧或一个LTE或NR时隙的长度的整数倍等,具体的不做限制。同步源的类型例如包括卫星或基站等。
在本申请实施例中,有关时隙的概念是指,特定子载波间隔下的一次传输所占用的时长。可以是1ms,0.5ms,0.25ms,0.125ms,或0.0625ms,或其它长度值。其占用的符号可以是14个,12个,7个,6个,4个,3个,或2个,或其它符号数等。例如,对于LTE系统而言,一个时隙的长度为0.5ms,一个子帧的长度为1ms。在NR系统中,不同的子载波间隔下一个时隙的长度不同,可以简单地认为是1ms除以2的整数倍。另外,NR系统也支持迷你时隙(mini-slot)的传输,即,只是用部分符号来做的时隙的传输。
然而,第一链路和第二链路可能有各自的候选同步源,而第一链路的候选同步源的类型和第二链路的候选同步源的类型可能是不同的。在本申请实施例中,如果要通过使得第一链路的同步源的类型和第二链路的同步源的类型相同的方式来实现第一链路和第二链路相互同步,则,如果第一链路的候选同步源的类型和第二链路的候选同步源的类型不同,第一终端设备可以确定其中优先级较高的候选同步源作为第一链路的同步源和第二链路 的同步源。例如第一链路的候选同步源的类型为卫星,第二链路的候选同步源的类型为基站,而基站的优先级高于卫星,则第一终端设备可以确定基站作为第一链路的同步源和第二链路的同步源,这样可以尽量以高优先级的同步源为准。或者,如果第一链路的候选同步源的类型和第二链路的候选同步源的类型不同,第一终端设备可以确定第一链路的同步源为第二链路的同步源,相当于以第一链路为准,这种方式可以尽量不改动第一链路对应的协议内容,或者说尽量不改动第一侧行传输技术对应的协议内容。再或者,如果第一链路的候选同步源的类型和第二链路的候选同步源的类型不同,第一终端设备可以根据第一链路的定时获取第二链路的定时,从而完成第一链路和第二链路的同步,这种方式也相当于是以第一链路为准,在尽量不改变第一链路对应的协议内容的情况下实现第二链路的同步。
第一终端设备可以获取用于第一链路的时域资源,也就是第一时域资源,第一时域资源可以包括分配给多个终端设备的用于第一链路的时域资源,这多个终端设备中包括第一终端设备,或者,第一时域资源也可以只是包括分配给第一终端设备的用于第一链路的时域资源。例如网络设备可以向第一终端设备发送配置信息,第一终端设备接收来自网络设备的配置信息后,可以根据配置信息确定用于第一链路的第一时域资源,例如网络设备可以通过广播消息或无线资源控制(radio resource control,RRC)消息等将配置信息发送给第一终端设备,当然,如果网络设备通过广播消息发送配置信息,则可能有多个终端设备都能接收该配置信息。在本申请实施例中,用于第一链路的资源,也可以理解为是用于第一侧行传输技术的资源,相应的,分配给第一链路的资源,也可以理解为是分配给第一侧行传输技术的资源。
作为第一时域资源的一种实施方式,第一终端设备获取第一时域资源,可以是具体获取分配给第一链路的发送资源,和/或,获取分配给第一链路的接收资源,也就是,获取的是分配给第一链路的发送资源或分配给第一链路的接收资源,或者分配给第一链路的发送资源和分配给第一链路的接收资源,第一时域资源就可以包括分配给第一链路的发送资源,和/或,分配给第一链路的接收资源。例如网络设备可以通过配置信息,明确向第一终端设备指示分配给第一链路的发送资源,和/或,分配给第一链路的接收资源。第一终端设备确定的第二时域资源就可以属于分配给第一链路的发送资源或接收资源,从而可以明确利用第二时域资源是发送或接收。另外,第一终端设备还可以发送第三指示信息,第三指示信息可以单独发送给第二终端设备,或者也可以通过广播或组播等方式发送,总之第二终端设备可以接收来自第一终端设备的第三指示信息,第三指示信息可以用于指示第一时域资源中包括的用于第一链路的发送资源和/或接收资源,从而使得第二终端设备也更便于确定第二时域资源。
例如,网络设备还可以为第一链路和第二链路分配公共资源,可以认为,这部分公共资源既可以作为第一链路的资源,也可以作为第二链路的资源。这部分公共资源可以包括发送资源和/或接收资源,也就是,包括发送资源或接收资源,或包括发送资源和接收资源。例如,第一终端设备获取第一时域资源,可以包括获取同时分配给第一链路和所述第一终端设备的用于第二链路的发送资源,和/或,同时分配给第一链路和所述第一终端设备的用于第二链路的接收资源,也就是,可以获取同时分配给第一链路和所述第一终端设备的用于第二链路的发送资源,或,同时分配给第一链路和所述第一终端设备的用于第二链路的接收资源,或同时分配给第一链路和所述第一终端设备的用于第二链路的发送资源和同时 分配给第一链路和所述第一终端设备的用于第二链路的接收资源。那么,同时分配给第一链路和第二链路的发送资源,第一链路和第二链路都可以用于发送,同时分配给第一链路和第二链路的接收资源,第一链路和第二链路都可以用于接收,使得第一终端设备更便于选择发送资源或接收资源。第二时域资源就可以属于同时分配给第一链路和第二链路的发送资源或接收资源。当然,如果第一时域资源包括同时分配给第一链路和所述第一终端设备的用于第二链路的发送资源,和/或,同时分配给第一链路和所述第一终端设备的用于第二链路的接收资源,则第一终端设备可以发送第四指示信息,第四指示信息可以单独发送给第二终端设备,或者也可以通过广播或组播等方式发送,总之第二终端设备可以接收来自第一终端设备的第四指示信息,第四指示信息可以用于指示同时分配给第一链路和所述第一终端设备的用于第二链路的发送资源,和/或,同时分配给第一链路和所述第一终端设备的用于第二链路的接收资源,从而使得第二终端设备也能够明确网络设备分配资源的方式。
另外,如果网络设备为第一链路和第二链路分配了公共资源,也就是确定了同时分配给第一链路和第一终端设备的用于第二链路的发送资源,和/或,同时分配给第一链路和第一终端设备的用于第二链路的接收资源,那么网络设备还可以为第一终端设备分配仅用于第二链路的资源,以供终端设备更好地传输第二链路的数据。例如,网络设备可以通过配置信息一并为第一终端设备配置分配给第一终端设备的仅用于第二链路的资源,终端设备接收配置信息后,就可以确定分配给第一终端设备的仅用于第二链路的资源。其中,分配给第一终端设备的仅用于第二链路的资源可以包括发送资源和/或接收资源,则第一终端设备可以确定分配给第一终端设备的仅用于第二链路的发送资源,和/或,确定分配给第一终端设备的仅用于第二链路的接收资源,也就是,第一终端设备可以确定分配给第一终端设备的仅用于第二链路的发送资源或分配给第一终端设备的仅用于第二链路的接收资源,或确定分配给第一终端设备的仅用于第二链路的发送资源和分配给第一终端设备的仅用于第二链路的接收资源。如果网络设备也为第一终端设备配置了分配给第一终端设备的仅用于第二链路的资源,则第一终端设备也可以发送第五指示信息,第五指示信息可以单独发送给第二终端设备,或者也可以通过广播或组播等方式发送,总之第二终端设备可以接收来自第一终端设备的第五指示信息,第五指示信息可以用于指示分配给第一终端设备的仅用于第二链路的资源,使得第二终端设备可以更为明确第一终端设备所选择的传输第二链路的数据的资源。作为一种可选的方式,第五指示信息所指示的分配给第一终端设备的仅用于第二链路的资源,可以包括分配给第一终端设备的仅用于第二链路的发送资源,和/或,分配给第一终端设备的仅用于第二链路的接收资源。
在本申请实施例中,用于第二链路的资源,也可以理解为是用于第二侧行传输技术的资源,相应的,分配给第二链路的资源,也可以理解为是分配给第二侧行传输技术的资源。
在本申请实施例中,第一终端设备还可以获取第二时域资源。其中,第一终端设备获取第二时域资源,可以有不同的方式。
例如,网络设备可以向第一终端设备发送第一指示信息,第一指示信息就用于指示第二时域资源,则第一终端设备接收来自网络设备的第一指示信息后,就可以根据第一指示信息确定第二时域资源。如果第一终端设备采用这种方式来获取第二时域资源,那么S31和S32的顺序就可以任意,例如S31可以在S32之前执行,或S31可以在S32之后执行,或S31和S32也可以同时执行。
或者,第一终端设备也可以自行根据第一时域资源确定第二时域资源,例如第一终端设备工作在自选资源的模式下(例如NR模式4),则第一终端设备可以自行根据第一时域资源确定第二时域资源。本申请实施例对于第一终端设备确定第二时域资源的方式不做限制。如果第一终端设备采用这种方式获取第二时域资源,则可以先执行S31再执行S32。
需要注意的是,这里所述的分配给终端设备的用于传输第二链路的第二时域资源,是终端设备根据第一时域资源额外确定的用于第二链路的时域资源,并不是网络设备本身分配给终端设备的用于第二链路的时域资源。可以理解为,在本申请实施例中,终端设备可以利用本身分配给第一链路的资源来用于第二链路传输数据,而至于终端设备是否本身也被分配了专用于第二链路的资源,本申请实施例并不限制。
例如一种情况为,第一信息对于时延的要求较高,或者较为重要或紧急,则第一终端设备可以只是在第二时域资源上采用第二侧行传输技术发送或接收第一信息,而无需再分配给第二侧行传输技术的资源上也采用第二侧行传输技术一并发送或接收第一信息,也就是,第一信息的传输可能只需用到第二时域资源。通过这种方式,可以尽量为对时延要求较高或较为重要或较为紧急的业务提供更多的传输机会。
或者,另一种情况为,第一信息的数据量较大,则第一终端设备除了在第二时域资源上采用第二侧行传输技术发送或接收第一信息之外,还可以在第三时域资源上采用第二传输技术发送或接收第一信息,也就是说,第一终端设备在第二时域资源和第三时域资源上采用第二侧行传输技术发送或接收第一信息,则第二终端设备在第二时域资源和第三时域资源上采用第二侧行传输技术相应接收或发送第一信息。第三时域资源就可以是用于采用第二侧行传输技术传输信息的资源。通过这种方式,可以使得较大数据量的业务能够尽量得到完整传输,减小业务传输的时延。
如果第一终端设备在第二时域资源上采用第二侧行传输技术发送第一信息,则第二终端设备就是第一信息的接收端,如果第一终端设备要在第二时域资源上采用第二侧行传输技术接收第一信息,则第二终端设备就是第一信息的发送端,因此,因为第一终端设备要在第二时域资源上通过第二链路发送或接收数据,则第一终端设备在确定第二时域资源后,可以将第二时域资源的信息指示给第二终端设备,以使得第二终端设备能够在第二时域资源上进行相应的接收或发送操作。例如,终端设备可以向第二终端设备发送第二指示信息,该第二指示信息可以用于指示第二时域资源,第二终端设备接收来自第一终端设备的第二指示信息后,就可以确定第二时域资源,从而可以在第二时域资源上采用第二侧行传输技术相应接收或发送第一信息。其中,为了确保第二终端设备能够正确接收第二指示信息,终端设备可以在用于第二侧行传输技术的资源上向第二终端设备发送第二指示信息。
例如,用于发送第二指示信息的时域位置,与第二时域资源所在的时域位置,二者之间的间隔可以大于或等于预定间隔。预定间隔例如是网络设备通过信令指示的,或者是通过协议预定义的,或者也可以是为终端设备预配置的。预定间隔可以大于0,相当于第二指示信息和第二时域资源之间有一定的时间间隔,以便第二终端设备接收第二指示信息后能有较为充足的响应时间,从而能够在第二时域资源上进行及时地接收或发送,或者预定间隔也可以是0,也就是,发送第二指示信息的时域位置和第二时域资源所在的时域位置可以是相邻的。
第二指示信息可以有多种指示方式。例如,第二指示信息可以用于指示第二时域资源所在的时间窗的信息,例如每个时间窗都有固定的时域位置和长度等,则第二指示信息所 指示的时间窗的信息只需要是时间窗的编号即可,或者第二指示信息所指示的时间窗的信息也可以是时间窗的时域起始位置和持续时长,或者第二指示信息所指示的时间窗的信息也可以是时间窗的时域结束位置和持续时长,或者第二指示信息所指示的时间窗的信息也可以是时间窗的时域起始位置和时域结束位置。或者也可以没有时间窗的概念,第二指示信息可以指示第二时域资源的时域起始位置和持续时长,或第二指示信息用于指示第二时域资源的时域结束位置和持续时长,或第二指示信息用于指示第二时域资源的时域起始位置和时域结束位置,等等。其中,第二指示信息所指示的位置,可以是子帧的编号或特定时子载波间隔下的时隙的编号等,例如第二指示信息指示的时域起始位置可以是时域起始位置所在的子帧的编号或特定时子载波间隔下的时隙的编号,第二指示信息指示的时域结束位置可以是时域结束位置所在的子帧的编号或特定时子载波间隔下的时隙的编号,等等。
例如在本申请实施例中,LTE-V2X与NR-V2X可以通过时分复用(time division multiplexing,TDM)模式传输,也就是说,第一链路和第二链路可以通过TDM模式传输,或者说,第一侧行传输技术和第二侧行传输技术可以通过TDM模式工作。例如网络设备可以事先为第一终端设备配置用于第一终端设备的第一链路的时域资源和第二链路的时域资源,或者也可以通过预配置的方式为第一终端设备配置用于第一终端设备的第一链路的时域资源和第二链路的时域资源,为第一终端设备配置的用于第一终端设备的第一链路的时域资源和第二链路的时域资源可以是彼此正交的时域资源,也就是对于第一终端设备来说,第一链路和第二链路可以工作在TDM模式下,可以看到在本申请实施例中,LTE-V2X和NR-V2X通过TDM的方式在一个终端设备中实现了共存。其中,对于第一终端设备来说,分配给第一链路的资源和分配给第二链路的资源,可以位于同一个载波上,或者也可以位于不同的载波上,下面分别介绍如何实现TDM。
例如,LTE-V2X与NR-V2X可以在同一个载波上进行TDM传输。例如可参考图4A,一个方框表示一个子帧(subframe)或一个时隙(slot),在载波0上,标识为1的方框是被分配给第一终端设备的用于第一链路的时域资源,标识为0的方框是被分配给第一终端设备的用于第二链路的时域资源,可以看到,用于第一链路的资源和用于第二链路的资源位于同一个载波上。通过这种配置方式,对于第一终端设备来说,第一链路和第二链路可以在正交的时域资源上各自实现通信。
LTE-V2X与NR-V2X也可以在不同的载波上进行TDM传输。例如可参考图4B,在载波0上,标识为1的方框是被分配给第一终端设备的用于第一链路的时域资源;在载波1上,标识为0的方框是被分配给第一终端设备的用于第二链路的时域资源。在带内模式(intra-band)载波聚合(carrier aggregation,CA)的场景下,载波0上的传输与载波1上的传输具有半双工的影响,也就是,当第一终端设备在载波0上发送信息的同时,第一终端设备不能在载波1上相同的时域资源上接收信息,同理,当第一终端设备在载波1上接收信息的同时,第一终端设备也不能在载波0上相同的时域资源上发送信息。因此本申请实施例确定了图4B所示的分配资源的方式,在不同载波上,为第一链路分配的时域资源和为第二链路分配的时域资源是在时间上完全正交的,因此可以克服LTE-V2X和NR-V2X在intra-band下的半双工问题。
作为第一终端设备确定第二时域资源的第一种方式,如果第一时域资源是分配给第一终端设备的用于第一侧行传输技术的时域资源,那么第一终端设备可以抢占第一时域资源中的部分资源或全部资源作为第二时域资源。通过这种抢占的方式,可以为第二链路的数 据提供更多的传输机会。例如,在第二链路的数据的优先级较高,或者对于时延的要求较高,或者较为紧急或较为重要时,可以采用这种方式来进行传输,从而尽量保证业务的需求。
例如,对于图4A所示的分配给第一链路的资源和分配给第二链路的资源位于同一个载波上的情况,标识为1的方框是被分配给第一终端设备的用于第一链路的时域资源,但第一终端设备在通过第二链路传输信息时,也可以抢占这部分资源。例如可参考图4C,虚线框所圈示的两个标识为1的方框,虽然是分配给第一终端设备的用于第一链路的时域资源,但第一终端设备的第二链路抢占了这部分资源,可以用于传输第二链路的信息。
再例如,对于图4B所示的分配给第一链路的资源和分配给第二链路的资源位于不同载波的情况,正常而言,当第一链路发送数据时,在相同的时间资源上的另一个载波上,第二链路应该也可以进行发送,这并不违反半双工的限制。但是由于在分配时域资源时是按照TDM模式分配的,因此,当第一终端设备在第一链路发送信息时,在相同的时间资源上的另一个载波上,不能在第二链路发送信息,这对时频资源是一种极大的浪费。因此本申请实施例提出,对于分配给第一链路的资源和分配给第二链路的资源位于不同载波的情况,第二链路也可以占用与第一链路相同的时域资源,从而提高对时频资源的利用率。例如可参考图4D,虚线框所圈示的载波1上的两个标识为0的方框,虽然这部分时域资源是分配给第一终端设备的用于第一链路的时域资源,但第一终端设备的第二链路抢占了这部分资源,可以用于传输第二链路的数据。
在本申请实施例中,第一终端设备可以通过支持NR-V2X的芯片来实现第二链路的传输,以及通过支持LTE-V2X的芯片来实现第一链路的传输,通过安装这两种芯片,也就实现了LTE-V2X和NR-V2X在第一终端设备内的共存。例如将支持NR-V2X的芯片称为NR模块,将支持LTE-V2X的芯片称为LTE模块,则可以理解为,NR模块可以抢占分配给LTE模块的资源。那么,要使得NR模块能够抢占分配给LTE模块的资源,NR模块就需要知道具体的分配给LTE模块的资源。例如LTE模块可以主动将用于第一终端设备的第一链路的发送资源和/或接收资源发送给NR模块,或者LTE模块也可以在接收NR模块发送的请求后将用于第一终端设备的第一链路的发送资源和/或接收资源发送给NR模块,则NR模块就可以确定用于第一终端设备的第一链路的发送资源和/或接收资源,具体的,是可以确定用于第一终端设备的第一链路的发送资源或接收资源,或确定用于第一终端设备的第一链路的发送资源和接收资源,从而NR模块就可以抢占第一链路的资源。
另外,虽然在前文中描述了,第一时域资源包括第二时域资源,或者说第二时域资源属于第一时域资源,这里需要澄清的是,这里的“包括”或“属于”,描述的只是时域上的关系,而在频域上,二者是不一定相同的,也就是,本申请实施例并不限制第一时域资源对应的频域资源和第二时域资源对应的频域资源之间的关系,较为灵活。例如,第一终端设备通过第一链路在第一时域资源的第一频域资源上发送或接收数据,第一终端设备通过第二链路在第二时域资源的第二频域资源上发送或接收数据,第一频域资源与第二频域资源可以相同,或者也可以不同。如果第一频域资源和第二频域资源不同,那么第一频域资源与第二频域资源可以位于不同的物理资源块(physical resource block,PRB),或位于不同的子信道,或位于不同的资源池,或位于不同的部分带宽(bandwidth part,BWP),或位于不同的载波等。例如图4C中,虚线框所圈示的两个标识为1的方框被第二链路占用,那么在载波0上,第一终端设备通过第一链路和第二链路都可能在该时域资源上发送 数据,此时第一时域资源对应的频域资源和第二时域资源对应的频域资源就是相同的。再例如图4D中,虚线框所圈示的载波1上的两个标识为1的方框被第二链路占用,例如在载波0上,第一终端设备通过第一链路在该时域资源上发送数据,在载波1上,第一终端设备通过第二链路在该时域资源上发送数据,而此时第一时域资源对应的频域资源和第二时域资源对应的频域资源就是不同的,位于不同的载波上。
在终端设备确定第二时域资源的第一种方式下,第一终端设备是使得第二链路抢占第一链路的资源,那么在被第二链路所抢占的第一链路的资源上,很可能第一终端设备在通过第一链路发送或接收数据,在本申请实施例中,如果满足第一条件,则第一终端设备可以选择停止第一链路的数据在第二时域资源上的发送或接收,或者也可以使得第一链路的数据和第二链路的数据在第二时域资源上同时发送或接收。例如,当满足第一条件,且第一终端设备在第二时域资源上通过第一链路做接收检测时,第一终端设备可以停止在第二时域资源做接收检测,和/或,当满足第一条件,且第一终端设备在第二时域资源上有通过第一链路传输的待发送的第一数据时,第一终端设备可以停止在第二时域资源发送第一数据(或将第一数据的发送功率从第一发送功率调整为第二发送功率,并按照第二发送功率,通过第一链路在第二时域资源上发送第一数据),也就是,当第一终端设备在第二时域资源上通过第一链路做接收检测时,第一终端设备可以停止在第二时域资源做接收检测,或,当第一终端设备在第二时域资源上有通过第一链路传输的待发送的第一数据时,第一终端设备停止在第二时域资源通过第一链路发送第一数据(或将第一数据的发送功率从第一发送功率调整为第二发送功率,并按照第二发送功率,通过第一链路在第二时域资源上发送第一数据),或,当第一终端设备在第二时域资源上在第一链路做接收检测时,第一终端设备可以停止在第二时域资源在第一链路做接收检测,以及,当第一终端设备在第二时域资源上有通过第一链路传输的待发送的第一数据时,第一终端设备停止在第二时域资源通过第一链路发送第一数据(或将第一数据的发送功率从第一发送功率调整为第二发送功率,并按照第二发送功率,通过第一链路在第二时域资源上发送第一数据)。通过这种方式,可以优先保证第二链路的数据在第二时域资源上得到传输。
以发送为例,当第一终端设备在第二时域资源上有通过第一链路传输的待发送的第一数据时,停止在第二时域资源通过第一链路发送第一数据,而只在第二时域资源发送第二链路的数据,或者说只在第二时域资源上通过第二链路发送数据,通过这种方式,可以减少第一链路和第二链路的干扰,提高数据发送质量。或者,当第一终端设备在第二时域资源上有通过第一链路传输的待发送的第一数据时,也可以将第一数据的发送功率从第一发送功率调整为第二发送功率,并按照第二发送功率,通过第一链路在第二时域资源上发送第一数据,例如第二发送功率低于第一发送功率,相当于可以降低第一链路的数据的发送功率,从而可以在第二时域资源上同时发送第一链路的数据和第二链路的数据,实现数据的同时发送,提高数据发送效率。
为了使得第二链路对于第一链路的资源的抢占更有意义,在本申请实施例中,第二链路要抢占第一链路的资源,或者说,要实现当第一终端设备在第二时域资源上通过第一链路做接收检测时,则第一终端设备可以停止在第二时域资源做接收检测,和/或,当第一终端设备在第二时域资源上有通过第一链路传输的待发送的第一数据时,第一终端设备可以停止在第二时域资源发送第一数据(或将第一数据的发送功率从第一发送功率调整为第二发送功率,并按照第二发送功率,通过第一链路在第二时域资源上发送第一数据),可以 是在第二链路满足第一条件的情况下,或者说是在第二链路的数据满足第一条件的情况下,在这种实施方式下,如果第二链路不满足第一条件,则可以不使得第二链路抢占第一链路的资源。
第一条件例如包括如下的至少一项:
第一终端设备通过第二链路传输的数据的优先级高于终端设备通过第一链路传输的数据的优先级;
第一终端设备通过第一链路传输的数据的优先级低于第一预定优先级;
第一终端设备通过第二链路传输的数据的传输时延小于预定时延;
第一终端设备通过第二链路传输的数据的传输时延小于预定时延,且第一终端设备通过第二链路传输的数据的优先级高于预定优先级;
第一终端设备通过第二链路传输的数据的传输距离小于预定距离,且第一终端设备通过第二链路传输的数据的优先级高于预定优先级;
第一终端设备通过第二链路传输的数据的数据包大小小于预定值,且第一终端设备通过第二链路传输的数据的优先级高于第二预定优先级;或,
第一终端设备通过第二链路传输的数据的发送功率小于预定发送功率,且第一终端设备通过第二链路传输的数据的优先级高于预定优先级。
例如第一条件包括第一终端设备通过第二链路传输的数据的优先级高于第一终端设备通过第一链路传输的数据的优先级,也就是确保在第二链路的数据的优先级较高时再使得第二链路抢占第一链路的资源,同理,如果第一条件包括第一终端设备通过第一链路传输的数据的优先级低于第一预定优先级,也就是确保在第一链路的数据的优先级较低时再使得第二链路抢占第一链路的资源,尽量保证高优先级的数据能够得到及时发送,也减小对于第一链路的数据的影响。
又例如第一条件包括第一终端设备通过第二链路传输的数据的传输时延小于预定时延,传输时延小,可能业务较为紧急,则可以使得第二链路抢占第一链路的资源,尽量为较为紧急的业务提供更多的传输机会。
再例如第一条件包括第一终端设备通过第二链路传输的数据的发送功率小于预定发送功率,且第一终端设备通过第二链路传输的数据的优先级高于预定优先级。例如,第一终端设备通过第二链路传输的数据的发送功率小于预定发送功率,而当前为第二链路分配的发送功率达不到第二链路的服务质量(quality of service,QoS)的要求(小于预定发送功率)。进一步地,如果第二链路的优先级高于预定优先级,则表明需要进一步为第二链路增加发送功率,否则第二链路传输的数据受到的影响是不可接受的。所以,可以通过这种方式来作为判断是否为第二链路配置更多或更高发送功率的条件,从而确保发送功率分配的合理性。
对于第一条件可能包括的其他项,不再过多示例。
前面介绍的第一终端设备确定第二时域资源的第一种方式,如果第一时域资源是分配给第一终端设备的时域资源,那么第一终端设备可以抢占第一时域资源中的部分资源或全部资源作为第二时域资源。下面再介绍作为第一终端设备确定第二时域资源的第二种方式,如果第一时域资源是分配给多个终端设备的时域资源,多个终端设备中包括第一终端设备,那么第一终端设备的第二链路可以利用第一时域资源中第一终端设备的第一链路未利用的资源。
例如,第一时域资源中包括分配给多个终端设备的第一链路的时域资源,第一终端设备的第一链路可能只利用第一时域资源中的部分时域资源,则第一终端设备的第二链路可以占用第一时域资源中未被第一终端设备的第一链路占用的时域资源来发送或接收数据,从而可以尽量提高对第一时域资源的利用率。
在这种情况下,第二时域资源可以属于第一终端设备的第一链路在第一时域资源中做测量操作之外的子帧,和/或,第二时域资源属于第一时域资源中第一终端设备的第一链路不发送数据的子帧。其中,测量操作例如包括控制信息的译码,或基于sidelink上传输的接收信号强度指示(received signal strength indicator,RSSI)所做的测量等。可选的,测量操作的子帧是第一时域资源中的子集。测量操作的子帧可以通过第一终端设备内部实现的方式指示给第二链路,也可以通过信令的方式指示给第二链路。信令可以是网络设备发送的或者预配置的。
另外在本申请实施例中,第一时域资源为用于第一链路的模式1或模式3的传输资源,第二时域资源为用于第二链路的模式1的传输资源;或,第一时域资源为用于第一链路的模式1或模式3的传输资源,第二时域资源为用于第二链路的模式2的传输资源;或,第一时域资源为用于第一链路的模式2或模式4的传输资源,第二时域资源为用于第二链路的模式1的传输资源;或,第一时域资源为用于第一链路的模式2或模式3的传输资源,第二时域资源为用于第二链路的模式2的传输资源。
第一链路例如为基于LTE的V2X链路,第二链路例如为基于NR的V2X链路,那么,第一链路的模式1,是指网络设备调度一次则做一次上行、下行或sidelink传输的模式;第一链路的模式3,是指网络设备调度一次,则做一段时间的上行、下行或sidelink传输的模式;第二链路的模式2,是指终端设备按随机资源的选择方式自行选择资源传输数据的模式,不依赖于网络设备的调度;第二链路的模式4,是指终端设备按照测量、监听的选择方式自行选择资源传输数据的模式。
例如第一侧行传输技术是基于LTE的V2X技术,第二侧行传输技术是基于NR的侧行传输技术,可以看到,本申请实施例提供的技术方案实现了这两种技术在第一终端设备内的共存。在本申请实施例中,第二时域资源属于第一时域资源,例如在通过第二链路传输数据时,还能利用分配给第一链路的资源来传输,从而为第二链路的数据提供更多的传输机会。例如,第二链路的数据可能对时延的要求较高,或业务的优先级较高或较为重要或较为紧急等,使得在通过第二链路传输数据时能够利用分配给第一链路的资源,有助于尽量满足对时延的要求较高,或业务的优先级较高或较为重要或较为紧急的业务的需求,例如可以减小传输时延等。
在图3所示的实施例中,网络设备在为第一链路和第二链路分配资源时,可以是按照TDM模式分配的。而如果网络设备在为第一链路和第二链路分配资源时按照频分复用(frequency division modulation,FDM)模式分配,则需要相应的方法来确定如何为第一链路和第二链路分配发送功率。鉴于此,下面介绍一种确定发送功率的方法,在这种方法中,可以确定为第一链路和第二链路分配的发送功率。
本申请实施例提供第一种确定发送功率的方法,请参见图5,为该方法的流程图。在下文的介绍过程中,以该方法应用于图1或图2所示的网络架构为例。另外,该方法可由两个通信装置执行,这两个通信装置例如为第三通信装置和第四通信装置,其中,第三通信装置可以是网络设备或能够支持网络设备实现该方法所需的功能的通信装置,或者第三 通信装置可以是终端设备或能够支持终端设备实现该方法所需的功能的通信装置,当然还可以是其他通信装置,例如芯片系统。对于第四通信装置也是同样,第四通信装置可以是网络设备或能够支持网络设备实现该方法所需的功能的通信装置,或者第四通信装置可以是终端设备或能够支持终端设备实现该方法所需的功能的通信装置,当然还可以是其他通信装置,例如芯片系统。且对于第三通信装置和第四通信装置的实现方式均不做限制,例如第三通信装置可以是网络设备,第四通信装置是终端设备,或者第三通信装置是网络设备,第四通信装置是能够支持终端设备实现该方法所需的功能的通信装置,等等。其中,网络设备例如为基站。
为了便于介绍,在下文中,以该方法由网络设备和终端设备执行为例,也就是,以第三通信装置是网络设备、第四通信装置均是终端设备为例。如果将本实施例是应用在图1所示的网络架构中,则下文中所述的网络设备可以是图1所示的网络架构中的网络设备,下文中所述的第一终端设备可以是图1所示的网络架构中的终端设备1,如果将本实施例是应用在图2所示的网络架构中,则下文中所述的网络设备可以是图2所示的网络架构中的网络设备,下文中所述的第一终端设备可以是图2所示的网络架构中的终端设备。当然,虽然本实施例可以用于图2所示的网络架构,但是本实施例中,第一终端设备所确定的第二发送功率是用于第一终端设备和第二终端设备之间通信的发送功率。
S51、第一终端设备获取第一发送功率和最大发送功率,所述第一发送功率为用于所述第一终端设备采用第一侧行传输技术发送数据的发送功率,所述最大发送功率为所述第一终端设备的最大发送功率,其中,分配给第一链路的资源和分配给第二链路的资源是频分复用的;
S52、所述第一终端设备根据所述第一发送功率和所述最大发送功率确定第二发送功率,所述第二发送功率为用于所述第一终端设备采用第二侧行传输技术发送数据的发送功率。
关于对第一侧行传输技术、第二侧行传输技术、第一链路和第二链路等概念,可以参考图3所示的实施例中的介绍。
在本申请实施例中,第一终端设备可以采用第一侧行传输技术传输信息,也可以采用第二侧行传输技术传输信息,可见对于第一终端设备来说,既可以采用第一侧行传输技术传输信息,也可以采用第二侧行传输技术传输信息,实现了两种侧行传输技术在一个终端设备中的共存。例如第一侧行传输技术为基于LTE的V2X技术,第二侧行传输技术为基于NR的V2X技术,那么本申请实施例也就是实现了基于LTE的V2X技术和基于NR的V2X技术在一个终端设备中的共存。
另外在本申请实施例中,第一链路和第二链路也可以是相互同步的,关于第一链路和第二链路同步的内容以及如何实现同步等内容,也可以参考图3所示的实施例中的介绍。
在本申请实施例中,分配给第一链路的资源和分配给第二链路的资源是频分复用的,也就是说,在相同的时间上,第一链路和第二链路可以在同一载波上或者在不同的载波上发送数据。
如果分配给第一链路的资源和分配给第二链路的资源位于同一载波,则可以实现在同一个载波的不同频域位置上同时发送或同时接收数据,例如请参考图6A,为分配给第一链路的资源和分配给第二链路的资源位于同一个载波的示意,在图6A中,例如分配给第一链路的资源的子载波间隔和分配给第二链路的资源的子载波间隔都是15kHz。如果分配给 第一链路的资源和分配给第二链路的资源位于不同的载波,则可以实现在不同载波上同时发送或同时接收数据。请参考图6B和图6C,为分配给第一链路的资源和分配给第二链路的资源位于不同载波的两种示意,在图6B中,例如分配给第一链路的资源的子载波间隔是15kHz,分配给第二链路的资源的子载波间隔是30kHz,则分配给第一链路的资源的一个时间单元的长度是分配给第二链路的资源的一个时间单元的长度的2倍,在图6C中,例如分配给第一链路的资源的子载波间隔是15kHz,分配给第二链路的资源的子载波间隔是60kHz,则分配给第一链路的资源的一个时间单元的长度是分配给第二链路的资源的一个时间单元的长度的4倍。
其中,最大发送功率例如为第一终端设备在一个载波上的最大发送功率,或者为第一终端设备在同一个频带的多个载波上的总的最大发送功率,或为网络设备为第一终端设备配置的最大发送功率,或第一终端设备在当前子帧、时隙或符号上的最大发送功率或最大可用的发送功率,或,网络设备为第一终端设备的当前的控制信道或数据信道上配置的最大发送功率,或,网络设备为第一终端设备配置的最大发送功率。其中,如果最大发送功率是第一终端设备在一个载波上的最大发送功率,或者是第一终端设备在同一个频带的多个载波上的总的最大发送功率,则可以理解为最大发送功率是第一终端设备的实际能力所支持的最大发送功率,而如果最大发送功率是网络设备为第一终端设备配置的最大发送功率,则配置的最大发送功率可以小于或等于第一终端设备的实际能力所支持的最大发送功率。
第一发送功率和/或最大发送功率例如是网络设备通过信令发送给第一终端设备的,则第一终端设备接收来自网络设备的信令后就可以获取第一发送功率和/或最大发送功率,该信令例如为广播消息或RRC信令等,或者第一发送功率和/或最大发送功率也可以是通过协议预定义的,或者第一发送功率和/或最大发送功率还可以是预配置给第一终端设备的。其中,第一发送功率和/或最大发送功率具体包括,第一发送功率或最大发送功率,或第一发送功率和最大发送功率。
作为一种可选的实施方式,第一发送功率可以等于最大发送功率,此时相当于不分配发送功率给第二侧行传输技术,而把全部发送功率都分配给了第一侧行传输技术。例如,通过第一侧行传输技术所传输的数据的优先级较高,或者较为紧急或较为重要时,可以考虑这种方式,从而尽量保证高优先级的或较为重要或较为紧急的业务能够得到优先传输。或者,作为另一种可选的实施方式,第一发送功率可以等于0,此时相当于不分配发送功率给第一侧行传输技术,而把全部发射功率都分配给第二侧行传输技术。例如,通过第二侧行传输技术所传输的数据的优先级较高,或者较为紧急或较为重要时,可以考虑这种方式,从而尽量保证高优先级的或较为重要或较为紧急的业务能够得到优先传输。
作为确定第二发送功率的一种方式,第一终端设备可以根据最大发送功率和第一发送功率之差来确定第二发送功率。
第一终端设备在获得第一发送功率和最大发送功率后,如果分配给第一链路的资源和分配给第二链路的资源位于同一个载波,第一终端设备可以根据如下方式确定第二发送功率:
P 2=P cmax–P 1        (公式1)
其中,P cmax表示第一终端设备在一个载波上的最大发送功率,可以是第一终端设备通过S51获取的,P 1表示第一发送功率,P 2表示第二发送功率。
或者,如果分配给第一链路的资源和分配给第二链路的资源位于intra-band的不同的载波,则第一终端设备可以根据如下方式确定第二发送功率:
P 2=P cmax2+(P cmax1-P 1)     (公式2)
或第一终端设备也可以根据如下方式确定第二发送功率:
P 2=P max-P 1       (公式3)
其中,P cmax2表示第一终端设备在分配给第二链路的资源所在的载波上的最大发送功率,P cmax1表示第一终端设备在分配给第一链路的资源所在的载波上的最大发送功率,P max表示第一终端设备在同一个频带的多个载波上的总的最大发送功率,这些参数的取值都可以是终端设备通过S51获取的。
作为确定第二发送功率的另一种方式,第一终端设备也可以根据最大发送功率和第一发送功率之差,以及第一终端设备到网络设备之间的路损,来确定第二发送功率,或者说,第一终端设备可以根据最大发送功率和第一发送功率之差,以及第三功率,来确定第二发送功率,第三功率例如为根据第一终端设备到网络设备之间的路损所确定的功率。
例如,第一终端设备根据最大发送功率和第一发送功率之差,以及根据第三功率,确定第二发送功率,一种实施方式如下:
第二发送功率由以下方式确定:min{P max-P 1,P 3},其中min{a,b}表示在数值a和b之间取较小的数,P max为通过S51获取的最大发送功率,其中,如果分配给第一链路的资源和分配给第二链路的资源位于同一个载波,则P max表示第一终端设备在一个载波上的最大发送功率,如果分配给第一链路的资源和分配给第二链路的资源位于intra-band的不同的载波,则P max表示第一终端设备在同一个频带的多个载波上的总的最大发送功率,P 1为第一发送功率,P 3为第三功率。
其中,P 3=10log 10M+P 0+αPL,M表示第二链路的带宽,P 0和α为用于确定P 3的功率参数,PL表示第一终端设备到网络设备之间的路损。
或者在本实施例中,第一终端设备还可以通过其他方式来确定第二发送功率,例如第一终端设备可以采用将要在后文中的图7所示的实施例中所提供的方式来确定第二发送功率,关于这些方式将在图7所示的实施例中介绍,此处不多赘述。
具体采用如上的何种方式来确定第二发送功率,例如可以由第一终端设备自行选择,或者可以通过协议预定义,或者由网络设备通过信令配置给第一终端设备,或者也可以预配置在第一终端设备中等,本申请实施例不做限制。
在本申请实施例中,第一链路和第二链路是频分复用的,那么第一链路和第二链路可以同时发送数据。而第一终端设备的总的发送功率是有限的,如果第一终端设备的总的发送功率无法满足第一链路和第二链路同时发送数据,则本申请实施例可以采取一定的措施。例如,当满足第一条件时,丢弃在第一时域资源待通过第一链路发送的数据,或将在第一时域资源待通过第一链路发送的数据的发送功率从第一发送功率调整为第三发送功率,再在第一时域资源按照第三发送功率通过第一链路发送数据,通过这种方式,可以优先保证第二链路的数据得以优先传输,例如,第二链路的数据的优先级较高,或者较为紧急或较为重要时,可以考虑这种方式,从而尽量保证高优先级的或较为重要或较为紧急的业务能够得到优先传输。那么,如果丢弃了在第一时域资源待通过第一链路发送的数据,则第一终端设备在第一时域资源通过第二发送功率,经第二链路发送数据,或者,如果将在第一时域资源待通过第一链路发送的数据的发送功率从第一发送功率调整为第三发送功率,则 第一终端设备在第一时域资源通过第二发送功率,经第二链路发送数据,以及在第一时域资源通过第三发送功率,经第一链路发送数据。也就是,如果第一终端设备的总的发送功率无法满足第一链路和第二链路同时发送数据,也可以在第一时域资源停止发送第一链路的数据,尽量保证第二链路的数据能够在第一时域资源得到及时发送;或者,如果第一终端设备的总的发送功率无法满足第一链路和第二链路同时发送数据,也可以调整第一链路的发送功率,一种调整方式例如为降低第一链路的发送功率,也就是,第三发送功率小于第一发送功率,从而使得第一终端设备可以通过第一链路和第二链路同时发送数据,尽量保证第一链路的数据和第二链路的数据都能得到及时发送。
而在前面介绍了,要丢弃在第一时域资源待通过第一链路发送的数据,或将在第一时域资源待通过第一链路发送的数据的发送功率从第一发送功率调整为第三发送功率,需要满足第一条件,如果不满足第一条件,则可以不丢弃在第一时域资源待通过第一链路发送的数据,也不将在第一时域资源待通过第一链路发送的数据的发送功率从第一发送功率调整为第三发送功率。可以理解为,如果满足第一条件,则需要尽量保证第二链路的数据能得到正常发送,而如果不满足第一条件,则需要尽量保证第一链路的数据能得到正常发送。
第一条件例如包括如下的至少一项:
第一终端设备通过第二链路传输的数据的优先级高于第一终端设备通过第一链路传输的数据的优先级;
第一终端设备通过第一链路传输的数据的优先级低于第一预定优先级;
第一终端设备通过第二链路传输的数据的传输时延小于预定时延;
第一终端设备通过第二链路传输的数据的传输时延小于预定时延,且第一终端设备通过第二链路传输的数据的优先级高于预定优先级;
第一终端设备通过第二链路传输的数据的传输距离小于预定距离,且第一终端设备通过第二链路传输的数据的优先级高于第二预定优先级;
第一终端设备通过第二链路传输的数据的数据包大小小于预定值,且第一终端设备通过第二链路传输的数据的优先级高于第二预定优先级;或
第一终端设备通过第二链路传输的数据的发送功率小于预定发送功率,且第一终端设备通过第二链路传输的数据的优先级高于第二预定优先级。
例如第一条件包括第一终端设备通过第二链路传输的数据的优先级高于第一终端设备通过第一链路传输的数据的优先级,也就是确保在第二链路的数据的优先级较高时再使得第二链路抢占第一链路的资源,同理,如果第一条件包括第一终端设备通过第一链路传输的数据的优先级低于第一预定优先级,也就是确保在第一链路的数据的优先级较低时再使得第二链路抢占第一链路的资源,尽量保证高优先级的数据能够得到及时发送,也减小对于第一链路的数据的影响。
又例如第一条件包括第一终端设备通过第二链路传输的数据的传输时延小于预定时延,传输时延小,可能业务较为紧急,则可以使得第二链路抢占第一链路的资源,尽量为较为紧急的业务提供更多的传输机会。
再例如第一条件包括第一终端设备通过第二链路传输的数据的发送功率小于预定发送功率,且终端设备通过第二链路传输的数据的优先级高于预定优先级,例如,第一终端设备通过第二链路传输的数据的发送功率小于预定发送功率,而当前为第二链路分配的发送功率达不到第二链路的QoS的要求(小于预定发送功率)。进一步地,如果第二链路的 优先级高于预定优先级,则表明需要进一步为第二链路增加发送功率,否则第二链路传输的数据受到的影响是不可接受的。所以,可以通过这种方式来作为判断是否为第二链路配置更多或更高发送功率的条件,从而确保发送功率分配的合理性。
对于第一条件可能包括的其他项,不再过多示例。
本申请实施例提供了能够合理地确定第二发送功率的方式,从而使得第一侧行传输技术和第二侧行传输技术在第一终端设备中能够以FDM的方式共存,例如,第一终端设备能够确定第二发送功率,从而通过第二链路和第一链路均能够发送数据。
如果网络设备在为第一链路和第二链路分配资源时按照FDM模式分配,则需要相应的方法来确定如何为第一链路和第二链路分配发送功率。除了图5所示的实施例之外,下面再介绍一种确定发送功率的方法,在这种方法中,也可以确定如何为第一链路和第二链路分配发送功率。
本申请实施例提供第二种确定发送功率的方法,请参见图7,为该方法的流程图。在下文的介绍过程中,以该方法应用于图1或图2所示的网络架构为例。另外,该方法可由两个通信装置执行,这两个通信装置例如为第五通信装置和第六通信装置,其中,第五通信装置可以是网络设备或能够支持网络设备实现该方法所需的功能的通信装置,或者第五通信装置可以是终端设备或能够支持终端设备实现该方法所需的功能的通信装置,当然还可以是其他通信装置,例如芯片系统。对于第六通信装置也是同样,第六通信装置可以是网络设备或能够支持网络设备实现该方法所需的功能的通信装置,或者第六通信装置可以是终端设备或能够支持终端设备实现该方法所需的功能的通信装置,当然还可以是其他通信装置,例如芯片系统。且对于第五通信装置和第六通信装置的实现方式均不做限制,例如第五通信装置可以是网络设备,第六通信装置是终端设备,或者第五通信装置是网络设备,第六通信装置是能够支持终端设备实现该方法所需的功能的通信装置,等等。其中,网络设备例如为基站。
为了便于介绍,在下文中,以该方法由网络设备和终端设备执行为例,也就是,以第五通信装置是网络设备、第六通信装置均是终端设备为例。如果将本实施例是应用在图1所示的网络架构中,则下文中所述的网络设备可以是图1所示的网络架构中的网络设备,下文中所述的第一终端设备可以是图1所示的网络架构中的终端设备1,如果将本实施例是应用在图2所示的网络架构中,则下文中所述的网络设备可以是图2所示的网络架构中的网络设备,下文中所述的第一终端设备可以是图2所示的网络架构中的终端设备。当然,虽然本实施例可以用于图2所示的网络架构,但是本实施例中,第一终端设备所确定的第二发送功率是用于第一终端设备和第二终端设备之间通信的发送功率。
S71、第一终端设备获取第一比值以及最大发送功率,所述第一比值为通过第一链路发送数据的发送功率与通过第二链路发送数据的发送功率之间的比值,或为通过第一链路发送数据的发送功率的功率谱密度与通过第二链路发送数据的发送功率的功率谱密度之间的比值,或为第二比值和第三比值的比值,所述第二比值为通过第一链路发送数据的发送功率的功率谱密度与用于第一链路的子载波间隔之间的比值,所述第三比值为通过第二链路发送数据的发送功率的功率谱密度与用于第二链路的子载波间隔之间的比值,所述最大发送功率为第一终端设备可用的最大发送功率,所述第一链路用于通过第一侧行传输技术传输信息,所述第一链路用于通过第二侧行传输技术传输信息;
S72、所述第一终端设备根据所述第一比值以及所述最大发送功率,确定第一发送功 率和第二发送功率,所述第一发送功率为用于通过第一链路发送数据的发送功率,所述第二发送功率为用于通过第二链路发送数据的发送功率。
关于对第一侧行传输技术、第二侧行传输技术、第一链路和第二链路等概念,可以参考图3所示的实施例中的介绍。
在本申请实施例中,第一时域资源用于采用第一侧行传输技术传输信息,第二时域资源用于采用第二侧行传输技术传输信息,可见对于第一终端设备来说,既可以采用第一侧行传输技术传输信息,也可以采用第二侧行传输技术传输信息,实现了两种侧行传输技术在一个终端设备中的共存。例如第一侧行传输技术为基于LTE的V2X技术(也可以描述为LTE-V2X),第二侧行传输技术为基于NR的V2X技术(也可以描述为NR-V2X),那么本申请实施例也就是实现了基于LTE的V2X技术和基于NR的V2X技术在一个终端设备中的共存。
其中,第一比值可以是预设的常数,例如通过协议预定义,或者预配置在第一终端设备中,例如第一比值等于1,或者也可以是其他取值;或者第一比值可以是网络设备通过信令指示给第一终端设备的参数;或者第一比值还可以是第一终端设备通过网络设备发送的信令所指示的参数计算得到的。
在本申请实施例中,第一链路和第二链路是相互同步的,关于同步、以及选择同步源等内容可以参考图5所示的实施例的相关描述。另外在本申请实施例中,分配给第一链路的资源和分配给第二链路的资源是频分复用的,也就是说,在相同的时间上,第一链路和第二链路可以在同一载波上或者在不同的载波上发送数据。对此同样可以参考图5所示的实施例中的有关图6A和图6B等的示意。
在本实施例中,假设第一链路的功率谱密度和第二链路的功率谱密度之间具有固定的关系。
作为第一终端设备确定第一发送功率和第二发送功率的第一种实施方式,假设第一链路的子载波间隔和第二链路的子载波间隔相同。因为P 1=M 1*PSD 1,P 2=M 2*PSD 2,P 1+P 2=P max,α=PSD 1/PSD 2,因此,第一终端设备可以根据公式P 1=α*M 1*P max/(α*M 1+M 2)计算第一发送功率,以及根据公式P 2=M 2*P max/(α*M 1+M 2)计算第二发送功率。
其中,P 1表示第一发送功率,α表示第一比值,此时第一比值为第一终端设备通过第一链路发送数据的发送功率的功率谱密度与通过第二链路发送数据的发送功率的功率谱密度之间的比值,M 1表示第一终端设备通过第一链路发送数据的带宽,M 2表示第一终端设备通过第二链路发送数据的带宽,P 2表示第二发送功率,P max表示最大发送功率,PSD 1表示第一链路的发送功率的功率谱密度,PSD 2表示第二链路的发送功率的功率谱密度。
作为确定第一发送功率和第二发送功率的第二种实施方式,假设第一链路的子载波间隔和第二链路的子载波间隔不同。因为P 1=M 1*P SCS1,P 2=M 2*P SCS2,P 1+P 2=P max,α=P SCS1/P SCS2,因此,第一终端设备可以根据公式P 1=α*M 1*P max/(α*M 1+M 2)计算第一发送功率,以及根据公式P 2=M 2*P max/(α*M 1+M 2)计算第二发送功率。
其中,P 1表示第一发送功率,α表示第一比值,此时第一比值为第一终端设备通过第一链路发送数据的发送功率与通过第二链路发送数据的发送功率之间的比值,M 1表示第一终端设备通过第一链路发送数据的带宽,M 2表示第一终端设备通过第二链路发送数据的带宽,P 2为第二发送功率,P max表示最大发送功率,P SCS1表示第一链路的发送功率,P SCS2表示第二链路的发送功率。
作为第一终端设备确定第一发送功率和第二发送功率的第三种实施方式,还可以配置θ作为第一比值,其中,θ为第二比值和第三比值的比值,也就是θ=第二比值/第三比值。其中,第二比值为第一终端设备通过第一链路发送数据的发送功率的功率谱密度与用于第一链路的子载波间隔之间的比值,第三比值为第一终端设备通过第二链路发送数据的发送功率的功率谱密度与用于第二链路的子载波间隔之间的比值。θ=(P SCS1/SCS 1)/(P SCS2/SCS 2)=(P SCS1/P SCS2)*(SCS 2/SCS 1)=α*2 μ,α=P SCS1/P SCS2。μ=μ 21,μ 1为用于第一链路的子载波间隔,μ 2为用于第二链路的子载波间隔,例如用于第一链路的子载波间隔为15kHz,则μ 1=0,用于第二链路的子载波间隔为30kHz,则μ 2=1,此时μ就等于1。第一终端设备可以根据θ和最大发送功率来计算第一发送功率和第二发送功率,例如一种计算方式为,第一终端设备根据公式P 1=θ*2 *M 1*P max/(θ*2 *M 1+M 2)计算第一发送功率,以及根据公式P 2=M 2*P max/(θ*2 *M 1+M 2)计算第二发送功率。
其中,P 1表示第一发送功率,θ表示第一比值,P 2表示第二发送功率,P max表示最大发送功率,M 1表示第一终端设备通过第一链路发送数据的带宽,M 2表示第一终端设备通过第二链路发送数据的带宽。
作为第一终端设备确定第一发送功率和第二发送功率的第四种实施方式,假设第一链路的发送功率与第二链路的发送功率之间的比值是固定的,该比值用β表示,也就是P 1/P 2=β,β即为第一比值。则第一终端设备可以根据公式P 2=P max/(1+β)计算第二发送功率,以及根据公式P 1=P max-P 2计算第一发送功率。
如上提供了几种第一终端设备确定第一发送功率和第二发送功率的方式,在实际应用中,第一终端设备可以采用以上几种方式中的任意一种来确定第一发送功率和第二发送功率,或者还可以采用其他方式来确定第一发送功率和第二发送功率,只要第一终端设备根据第一比值和最大发送功率确定第一发送功率和第二发送功率即可,本申请实施例不限制第一终端设备具体根据第一比值和最大发送功率确定第一发送功率和第二发送功率的方式。而且,在图5所示的实施例中,第一终端设备也可以利用图7所示的实施例所介绍的方式来确定第二发送功率。
另外,第一终端设备根据如上的各种方式所确定的第二发送功率,可以是第一终端设备用于第二链路的最大发送功率,第一终端设备在通过第二链路发送数据时,所实际使用的发送功率可以小于或等于第二发送功率。对于第一发送功率来说也是同样的,第一终端设备根据如上的各种方式所确定的第一发送功率,可以是第一终端设备用于第一链路的最大发送功率,第一终端设备在通过第一链路发送数据时,所实际使用的发送功率可以小于或等于第一发送功率。
具体采用如上的何种方式来确定第一发送功率和第二发送功率,例如可以由第一终端设备自行选择,或者可以通过协议预定义,或者由网络设备通过信令配置给第一终端设备,或者也可以预配置在第一终端设备中等,本申请实施例不做限制。
本申请实施例提供了能够确定第一发送功率和第二发送功率的方式,从而使得第一侧行传输技术和第二侧行传输技术在第一终端设备中能够以FDM的方式共存,例如,第一终端设备能够确定第二发送功率,从而通过第二链路和第一链路均能够发送数据。在本申请实施例中,第一终端设备可以根据配置的参数确定第一发送功率和第二发送功率,有助于提高确定第一链路和第二链路上的发送功率的合理性,从而使得第一链路和第二链路更合理地在一个终端设备内共存。
