Description

一种功率控制方法和网络设备以及终端设备 技术领域
本申请实施例涉及通信领域,尤其涉及一种功率控制方法和网络设备以及终端设备。
背景技术
目前无线通信系统大规模应用部署,可向多个用户提供各种类型的通信,例如,语音、数据、多媒体业务等。在无线通信系统中接入到基站的用户设备也越来越多,不同基站的射频覆盖范围之间也不可避免的存在射频干扰的问题。因此,需要对于无线通信系统进行干扰管理。
在当前的长期演进(Long Term Evolution,LTE)技术的讨论过程中,对于LTE系统的应用场景,基站实行功率控制是解决射频干扰问题的一种处理方法。当一个用户设备的发射功率较大时,该用户设备发送的信号可能会对其它用户设备产生强的干扰。为了降低该用户设备对其它用户设备的干扰,基站可以通过调整该用户设备的发射功率以减轻对其它用户设备的干扰。
现有技术中,基站只根据本服务小区设置参考信号接收功率门限,用户设备也只测量本服务小区的参考信号接收功率,从而用户设备采用的功率控制存在控制精度差的问题,仍存在一个用户设备对其它用户设备的射频干扰问题,用户设备该如何进行功率控制仍是需要解决的问题。
发明内容
本申请实施例提供了一种功率控制方法和网络设备以及终端设备,以期对终端设备采用的上行发射功率进行精确控制,减轻对相邻小区的干扰。
第一方面,本申请实施例提供一种功率控制方法,包括:网络设备向终端设备发送第一信息,和/或,所述网络设备向所述终端设备发送第二信息,其中,所述第一信息包括:第一参考信号接收功率门限,所述第二信息包括:第二参考信号接收功率门限;所述网络设备向所述终端设备发送第三信息,所述第三信息包括:第一功率值,所述第一功率值用于指示当所述终端设备的服务小区的参考信号接收功率大于所述第一参考信号接收功率门限、且所述终端设备的相邻小区的参考信号接收功率大于所述第二参考信号接收功率门限时,或当所述服务小区的参考信号接收功率大于所述第一参考信号接收功率门限、且所述相邻小区的参考信号接收功率大于所述第一参考信号接收功率门限时,所述终端设备发送上行信号的发射功率不能超过所述第一功率值。
本申请实施例中,网络设备可向终端设备指示第一参考信号接收功率门限、第二参考信号接收功率门限,还可以向终端设备指示第一功率值,因此网络设备指示了终端设备的发射功率控制既考虑到与服务小区的参考信号接收功率,也考虑到与相邻小区的参考信号接收功率。只有当终端设备对相邻小区造成比较大的干扰时,才会限制终端设备允许发送的最大功率,从而减轻了对相邻小区的上行干扰。
在第一方面的一个可能的设计中,所述方法还包括:所述网络设备向所述终端设备发 送第四信息,所述第四信息包括:第一数值M,所述第四信息用于指示至少M个相邻小区的参考信号接收功率大于所述第二参考信号接收功率门限时所述终端设备发送上行信号的发射功率不能超过所述第一功率值。在本申请实施例中,网络设备可以向终端设备指示M,M是终端设备的相邻小区的参考信号接收功率大于第二参考信号接收功率门限的相邻小区个数,即网络设备还可以要求终端设备统计终端设备的相邻小区的参考信号接收功率大于第二参考信号接收功率门限的相邻小区个数,即网络设备要求终端设备的相邻小区的参考信号接收功率大于第二参考信号接收功率门限的相邻小区个数至少有M个时才能将上行信号的发射功率不能超过第一功率值,因此只有当终端设备对相邻小区造成比较大的干扰时,才会限制终端设备允许发送的最大功率,从而减轻了对相邻小区的上行干扰。
在第一方面的一个可能的设计中,所述方法还包括:所述网络设备向所述终端设备发送第五信息,所述第五信息包括:第二功率值,所述第二功率值是所述终端设备发送上行信号能够使用的最大发射功率值。在本申请实施例中,网络设备还可以发送第五信息,网络设备通过第五信息向终端设备发送第二功率值,终端设备接收到该第五信息之后,终端设备可以确定出第二功率值,第二功率值是终端设备发送上行信号能够使用的最大发射功率值,因此终端设备发送上行信号所采用的发射功率不能超过该第二功率值,从而减少终端设备对相邻小区的上行干扰。
在第一方面的一个可能的设计中,所述第一功率值小于所述第二功率值。在本申请实施例中,第二功率值可以是网络设备为服务小区下的所有终端设备规定的最大发射功率值,而第一功率值可以网络设备为特定类型的终端设备发送的最大发射功率值,例如第一功率值是网络设备为飞行器终端设备所规定的最大发射功率值,从而减少飞行器终端设备对相邻小区的上行干扰。
在第一方面的一个可能的设计中,所述第一参考信号接收功率门限为无穷小的值,或者为负无穷大的值。在本申请实施例中,网络设备在确定第一参考信号接收功率门限时,网络设备可以将第一参考信号接收功率门限设置为无穷小的值或者负无穷大的值,从而该第一参考信号接收功率门限与终端设备的参考信号接收功率进行功率值比较时,该终端设备的参考信号接收功率更容易超过第一参考信号接收功率门限。
在第一方面的一个可能的设计中,所述第一信息和所述第二信息通过同一个系统信息块传输给所述终端设备。在本申请实施例中,网络设备可以将第一信息和第二信息承载在系统信息块1中,然后将系统信息块1传输给终端设备,从而终端设备接收到系统信息块1之后,终端设备可以通过该系统信息块1得到第一信息和第二信息。第一信息和第二信息通过同一个系统信息块传输给终端设备,从而提高信息发送的效率,提高对传输资源的利用率。
在第一方面的一个可能的设计中,所述方法还包括:所述网络设备获取所述终端设备的能力信息,所述终端设备的能力信息包括如下信息中的至少一种:所述终端设备的位置信息、高度信息和飞行能力信息;所述网络设备根据所述终端设备的能力信息确定所述第一功率值。在本申请实施例中,网络设备获取到终端设备的上述能力信息之后,网络设备根据终端设备的上述能力信息可以为该终端设备确定的第一功率值的大小。举例说明,网络设备通过终端设备的飞行能力信息确定该终端设备是否是飞行器终端设备,因为飞行器 终端设备处于空中,飞行器终端设备在空中时周围会存在更多的相邻小区,因此该飞行器终端设备更容易对相邻小区产生干扰,从而网络设备可以减小第一功率值的大小,从而降低对相邻小区的干扰。
在第一方面的一个可能的设计中,所述第一参考信号接收功率门限小于所述第二参考信号接收功率门限。本申请实施例中第一参考信号信号接收功率门限用于与终端设备测量到的服务小区的参考信号接收功率进行功率值比较,或者第一参考信号信号接收功率门限用于与终端设备测量到的相邻小区的参考信号接收功率进行功率值比较,第二参考信号信号接收功率门限用于与终端设备测量到的相邻小区的参考信号接收功率进行功率值比较。因此设置第二参考信号接收功率门限的门限值大于第一参考信号接收功率门限的门限值,终端设备的相邻小区的参考信号接收功率可能不超过第二参考信号接收功率门限,使得终端设备采用的上行信号的发射功率不超过后续的第一功率值,因此可以降低终端设备对相邻小区的上行干扰。
第二方面,本申请实施例还提供一种功率控制方法,包括:终端设备接收网络设备发送的第一信息,和/或,所述终端设备接收所述网络设备发送的第二信息,其中,所述第一信息包括:第一参考信号接收功率门限,所述第二信息包括:第二参考信号接收功率门限;所述终端设备接收所述网络设备发送的第三信息,所述第三信息包括:第一功率值;所述终端设备确定服务小区的参考信号接收功率,以及所述终端设备确定相邻小区的参考信号接收功率;当所述服务小区的参考信号接收功率大于所述第一参考信号接收功率门限、且所述相邻小区的参考信号接收功率大于所述第二参考信号接收功率门限时,所述终端设备确定发送上行信号的发射功率不能超过所述第一功率值;或,当所述服务小区的参考信号接收功率大于所述第一参考信号接收功率门限、且所述相邻小区的参考信号接收功率大于所述第一参考信号接收功率门限时,所述终端设备确定发送上行信号的发射功率不能超过所述第一功率值。
本申请实施例中,网络设备可向终端设备指示第一参考信号接收功率门限、第二参考信号接收功率门限,还可以向终端设备指示第一功率值,因此网络设备指示了终端设备的发射功率控制既考虑到与服务小区的参考信号接收功率,也考虑到与相邻小区的参考信号接收功率。只有当终端设备对相邻小区造成比较大的干扰时,才会限制终端设备允许发送的最大功率,从而减轻了对相邻小区的上行干扰。
在第二方面的一个可能的设计中,所述方法还包括:所述终端设备接收所述网络设备发送的第四信息,所述第四信息包括:第一数值M,所述第四信息用于指示至少M个相邻小区的参考信号接收功率大于所述第二参考信号接收功率门限时所述终端设备发送上行信号的发射功率不能超过所述第一功率值,或者所述终端设备根据预先规定至少M个相邻小区的参考信号接收功率大于所述第二参考信号接收功率门限时所述终端设备发送上行信号的发射功率不能超过所述第一功率值;所述相邻小区的参考信号接收功率大于所述第二参考信号接收功率门限,具体为:至少M个相邻小区的参考信号接收功率大于所述第二参考信号接收功率门限。
在本申请实施例中,网络设备可以向终端设备指示M,M是终端设备的相邻小区的参考信号接收功率大于第二参考信号接收功率门限的相邻小区个数,即网络设备还可以要求终端设备统计终端设备的相邻小区的参考信号接收功率大于第二参考信号接收功率门限的相 邻小区个数,即网络设备要求终端设备的相邻小区的参考信号接收功率大于第二参考信号接收功率门限的相邻小区个数至少有M个时才能将上行信号的发射功率不能超过第一功率值,因此只有当终端设备对相邻小区造成比较大的干扰时,才会限制终端设备允许发送的最大功率,从而减轻了对相邻小区的上行干扰。
在第二方面的一个可能的设计中,所述方法还包括:所述终端设备接收所述网络设备发送的第五信息,所述第五信息包括:第二功率值,所述第二功率值是所述终端设备发送上行信号能够使用的最大发射功率值。在本申请实施例中,网络设备还可以发送第五信息,网络设备通过第五信息向终端设备发送第二功率值,终端设备接收到该第五信息之后,终端设备可以确定出第二功率值,第二功率值是终端设备发送上行信号能够使用的最大发射功率值,因此终端设备发送上行信号所采用的发射功率不能超过该第二功率值,从而减少终端设备对相邻小区的上行干扰。
在第二方面的一个可能的设计中,所述方法还包括:当所述服务小区的参考信号接收功率大于所述第一参考信号接收功率门限、且所述相邻小区的参考信号接收功率小于或等于所述第二参考信号接收功率门限时,所述终端设备确定发送上行信号的发射功率不能超过所述第二功率值。
在第二方面的一个可能的设计中,所述第一参考信号接收功率门限为无穷小的值,或者为负无穷大的值。在本申请实施例中,网络设备在确定第一参考信号接收功率门限时,网络设备可以将第一参考信号接收功率门限设置为无穷小的值或者负无穷大的值,从而该第一参考信号接收功率门限与终端设备的参考信号接收功率进行功率值比较时,该终端设备的参考信号接收功率更容易超过第一参考信号接收功率门限。
第三方面,本申请实施例还提供一种网络设备,包括:第一发送模块,用于向终端设备发送第一信息,和/或,向所述终端设备发送第二信息,其中,所述第一信息包括:第一参考信号接收功率门限,所述第二信息包括:第二参考信号接收功率门限;第二发送模块,用于向所述终端设备发送第三信息,所述第三信息包括:第一功率值,所述第一功率值用于指示当所述终端设备的服务小区的参考信号接收功率大于所述第一参考信号接收功率门限、且所述终端设备的相邻小区的参考信号接收功率大于所述第二参考信号接收功率门限时,或当所述服务小区的参考信号接收功率大于所述第一参考信号接收功率门限、且所述相邻小区的参考信号接收功率大于所述第一参考信号接收功率门限时,所述终端设备发送上行信号的发射功率不能超过所述第一功率值。
本申请实施例中,网络设备可向终端设备指示第一参考信号接收功率门限、第二参考信号接收功率门限,还可以向终端设备指示第一功率值,因此网络设备指示了终端设备的发射功率控制既考虑到与服务小区的参考信号接收功率,也考虑到与相邻小区的参考信号接收功率。只有当终端设备对相邻小区造成比较大的干扰时,才会限制终端设备允许发送的最大功率,从而减轻了对相邻小区的上行干扰。

具体实施方式
本申请实施例提供了一种功率控制方法和网络设备以及终端设备,能够实现对终端设备采用的上行发射功率进行精确控制,减轻对相邻小区的干扰。
下面结合附图,对本申请的实施例进行描述。
本申请的说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象,而不必用于描述特定的顺序或先后次序。应该理解这样使用的术语在适当情况下可以互换,这仅仅是描述本申请的实施例中对相同属性的对象在描述时所采用的区分方式。此外,术语“包括”和“具有”以及他们的任何变形,意图在于覆盖不排他的包含,以便包含一系列单元的过程、方法、系统、产品或设备不必限于那些单元,而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它单元。
首先对本申请功率控制方法应用的系统架构进行简介,本申请主要应用于LTE系统或高级的长期演进(LTE-A,LTE Advanced)系统。本申请也可以应用于其它的通信系统,例如,宽带码分多址(Wideband Code Division Multiple Access,WCDMA)、时分同步码分多址(Time Division-Synchronous Code Division Multiple Access,TD-SCDMA)等系统,只要该通信系统中存在实体可以发送上行数据,该通信系统中存在其它实体可以接收该上行数据即可。
如图1所示,为本申请实施例提供的系统组成结构示意图,该系统可包括:网络设备和终端设备,其中,终端设备可以有一个或多个。本申请实施例中所述的通信系统主要是无线通信系统,例如接入点和终端之间的传输,可以通过无线电波来传输。不限定的是,也可以通过可见光、激光、红外、光量子、电力线、光纤、同轴电缆、铜绞线等传输。其中,终端设备是指在通信过程中使用通信资源的一方,例如终端设备可以是手机终端、智能移动终端、无人机终端等。本申请所涉及到的终端设备各种具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其它处理设备,以及各种形式的用户设备(User Equipment,UE),移动台(Mobile station,MS),终端(terminal),终端设备(Terminal Equipment)等等。为方便描述,本申请中,上面提到的设备统称为用户设备或UE。网络设备是指在通信过程中用于管理通信资源、提供通信服务的一方,例如网络设备可以是基站,也可以是提供通信服务的服务器、接入点等设备,本申请所涉及到的网络设备可以包括基站(base station,简称BS),网络设备是一种部署在无线接入网中用以为UE提供无线通信功能的装置。所述基站可以包括各种形式的宏基站,微基站,中继站,接入点等等。在采用不同的无线接入技术的系统中,具备基站功能的设备的名称可能会有所不同,例如在LTE系统中,称为演进的节点B(evolved NodeB简称:eNB或者eNodeB),在NR系统中,称为gNB,在第三代3G系统中,称为节点B(Node B)等等。
本申请实施例中传输可以是发送或接收。若一侧设备的传输是发送,则该侧设备对应的另一侧通信设备的处理是接收;若一侧设备的传输是接收,则该侧设备对应的另一侧通信设备的处理是发送;反之亦然。本申请实施例中的覆盖增强可以是重复传输、扩频传输、重传、捆绑时间间隔传输、窄带(如子载波调度)传输、超窄带(如带宽是几十赫兹到十几千赫兹)传输、提高功率谱密度传输、放松需求传输、不断尝试传输中的一种或多种。低成本终端或低复杂度终端是指终端设备的工作带宽小于非低成本终端或非低复杂度终端 的工作带宽。工作带宽可以是处理带宽、射频处理带宽、基带处理带宽中的一种或多种。例如,工作带宽为1.4MHz(或200KHz,或180KHz)。工作带宽是具有特定频率宽度的频率资源。工作带宽可以由一个或多个子载波(如一个子载波的大小是15Khz,或2.5KHz,或3.75KHz)构成,也可以由一个或多个资源块构成。
请参阅如图2所示,为本申请功率控制方法应用在通信系统中的系统架构图,如图1所示,基站(英文名称Base station)和用户设备(User Equipment、UE)1~UE6组成一个通信系统,在该通信系统中,基站发送系统信息、RAR消息和寻呼消息中的一种或多种给UE1~UE6中的一个或多个UE,基站为本申请功率控制方法中的发送端设备,UE1~UE6为本申请功率控制方法中的接收端设备。此外,UE4~UE6也组成一个通信系统,在该通信系统中,UE5可以作为基站的功能实现,UE5可以发送系统信息、RAR消息和寻呼消息中的一种或多种给UE4和UE6中的一个或多个UE。又如,在该通信系统中,UE1~UE6可以发送上行数据给基站,基站需要接收UE1~UE6发送的上行数据。其中,UE1和UE2是无人机UE。UE4~UE6也可以组成一个通信系统。在该通信系统中,UE4、UE6可以发送上行数据给UE5,UE5需要接收UE4、UE6发送的上行数据。
以下分别进行详细说明。
本申请功率控制方法的一个实施例,可应用于网络设备向终端发送控制信息的场景中,通过限制终端设备允许发送的最大发射功率,从而减轻了对相邻小区的上行干扰。请参阅图3所示,该功率控制方法,可以包括如下步骤:
301、网络设备向终端设备发送第一信息,和/或,网络设备向终端设备发送第二信息,其中,第一信息包括:第一参考信号接收功率门限,第二信息包括:第二参考信号接收功率门限。
在本申请实施例中,网络设备可以向终端设备发送小区参考信号(Cell Reference Signal,CRS),终端设备对该CRS进行测量接收,从而终端设备可以生成参考信号接收功率(Reference Singnal Received Power,RSRP),RSRP是终端设备接收到的小区公共参考信号的功率值,数值为测量带宽内单个资源粒子功率的线性平均值,反映的是本小区有用信号的强度。举例说明,对于LTE系统的应用场景,LTE系统下基站需要在某些符号上发送小区参考信号,用户设备通过测量可知本小区的参考信号接收功率。
在本申请实施例中,网络设备为终端设备的参考信号接收功率设置门限,例如网络设备可以生成一个参考信号接收功率门限,例如生成第一参考信号接收功率门限,或者生成第二参考信号接收功率门限。网络设备也可以生成两个参考信号接收功率门限,分别为:第一参考信号接收功率门限和第二参考信号接收功率门限。其中,第一参考信号接收功率门限和第二参考信号接收功率门限各自的门限取值可以根据应用场景由网络设备来确定。
在本申请的一些实施例中,第一参考信号接收功率门限小于第二参考信号接收功率门限。网络设备可以设置第一参考信号接收功率门限小于第二参考信号接收功率门限,即第二参考信号接收功率门限的门限值大于第一参考信号接收功率门限的门限值。本申请实施例中第一参考信号信号接收功率门限用于与终端设备测量到的服务小区的参考信号接收功率进行功率值比较,或者第一参考信号信号接收功率门限用于与终端设备测量到的相邻小区的参考信号接收功率进行功率值比较,第二参考信号信号接收功率门限用于与终端设备 测量到的相邻小区的参考信号接收功率进行功率值比较。因此设置第二参考信号接收功率门限的门限值大于第一参考信号接收功率门限的门限值,终端设备的相邻小区的参考信号接收功率可能不超过第二参考信号接收功率门限,使得终端设备采用的上行信号的发射功率不超过后续的第一功率值,因此可以降低终端设备对相邻小区的上行干扰。
在本申请的一些实施例中,第一参考信号接收功率门限为无穷小的值,或者为负无穷大的值。其中,网络设备在确定第一参考信号接收功率门限时,网络设备可以将第一参考信号接收功率门限设置为无穷小的值或者负无穷大的值,从而该第一参考信号接收功率门限与终端设备的参考信号接收功率进行功率值比较时,该终端设备的参考信号接收功率更容易超过第一参考信号接收功率门限。举例说明,基站可以将第一参考信号接收功率门限值设置为很小的值或者设置为无穷小的值,其中很小的值所采用的数量级比较可以由基站根据具体场景来设置,此处不做限定。
在本申请实施例中,网络设备生成第一参考信号接收功率门限和第二参考信号接收功率门限之后,网络设备可以通过第一信息向终端设备发送第一参考信号接收功率门限,则终端设备接收到第一信息之后,终端设备解析该第一信息可以得到第一参考信号接收功率门限,其中网络设备和终端设备之间的通信过程可以使用无线通信连接来实现,例如可以使用系统信息来承载该第一信息。同样的,网络设备还可以通过第二信息向终端设备发送第二参考信号接收功率门限,则终端设备接收到第二信息之后,终端设备解析该第二信息可以得到第二参考信号接收功率门限。
在本申请的一些实施例中,第一信息和第二信息通过同一个系统信息块(System Information Block,SIB)传输给终端设备。如图4和图5-a所示,图4为本申请实施例提供的一种系统信息块的实现方式示意图,图5-a为本申请实施例提供的另一种系统信息块的实现方式示意图。网络设备可以将第一信息和第二信息承载在系统信息块1中,然后将系统信息块1传输给终端设备,从而终端设备接收到系统信息块1之后,终端设备可以通过该系统信息块1得到第一信息和第二信息。第一信息和第二信息通过同一个系统信息块传输给终端设备,从而提高信息发送的效率,提高对传输资源的利用率。不限定的是,在本申请的另一些实施例中,第一信息和第二信息也可以通过不同的系统信息块传输给终端设备,则网络设备可以分别传输第一信息和第二信息,从而可以采用灵活的方式各自传输,便于终端设备的接收。
302、网络设备向终端设备发送第三信息,第三信息包括:第一功率值,第一功率值用于指示当终端设备的服务小区的参考信号接收功率大于第一参考信号接收功率门限、且终端设备的相邻小区的参考信号接收功率大于第二参考信号接收功率门限时,或当服务小区的参考信号接收功率大于第一参考信号接收功率门限、且相邻小区的参考信号接收功率大于第一参考信号接收功率门限时,终端设备发送上行信号的发射功率不能超过第一功率值。
在本申请实施例中,网络设备除了发送第一信息和/或第二信息,网络设备还可以向终端设备发送第一功率值,网络设备可以通过第三信息向终端设备发送第一功率值,终端设备接收到第三信息之后,终端设备解析该第三信息可以得到第一功率值。
其中,第一功率值可以用于指示如下两种情况:1)、当终端设备的服务小区的参考信号接收功率大于第一参考信号接收功率门限、且终端设备的相邻小区的参考信号接收功率 大于第二参考信号接收功率门限时,终端设备发送上行信号的发射功率不能超过第一功率值。2)当服务小区的参考信号接收功率大于第一参考信号接收功率门限、且相邻小区的参考信号接收功率大于第一参考信号接收功率门限时,终端设备发送上行信号的发射功率不能超过第一功率值。因此只有当终端设备对相邻小区造成比较大的干扰时,才会限制终端设备允许发送的最大发射功率,从而减轻了对邻小区的上行干扰。
如图4所示,网络设备可以将第一信息、第二信息和第三信息都承载在系统信息块1中,然后将系统信息块1传输给终端设备,从而终端设备接收到系统信息块1之后,终端设备可以通过该系统信息块1得到第一信息、第二信息和第三信息。如图5-a和图5-b所示,第一信息和第二信息通过系统信息块1传输给终端设备,第三信息可以通过不同的系统信息块传输给终端设备,例如第三信息通过系统信息块2发送给终端设备,从而可以采用灵活的方式各自传输,便于终端设备的接收。
需要说明的是,前述步骤301和步骤302之间没有先后顺序,可以先执行步骤301,后执行步骤302,也可以先执行步骤302再执行步骤301,还可以同时执行,此处不做限定。
在本申请的一些实施例中,本申请实施例提供的功率控制方法,除了执行前述步骤之外,还可以包括如下步骤:
A1、网络设备获取终端设备的能力信息,终端设备的能力信息包括如下信息中的至少一种:终端设备的位置信息、高度信息和飞行能力信息;
A2、网络设备根据终端设备的能力信息确定第一功率值。
其中,终端设备可以生成该终端设备的位置信息、高度信息和飞行能力信息,位置信息可以通过终端设备的定位系统来得到,终端设备的高度信息可以通过终端设备的高度测量设备得到,飞行能力信息是指终端设备是否具有飞行能力,通过该飞行能力信息可以区分地面上的终端设备以及飞行器终端设备,例如该飞行器终端设备具体可以是无人机UE。网络设备获取到终端设备的上述能力信息之后,网络设备根据终端设备的上述能力信息可以为该终端设备确定的第一功率值的大小。举例说明,网络设备通过终端设备的飞行能力信息确定该终端设备是否是飞行器终端设备,因为飞行器终端设备处于空中,飞行器终端设备在空中时周围会存在更多的相邻小区,因此该飞行器终端设备更容易对相邻小区产生干扰,从而网络设备可以减小第一功率值的大小,从而降低对相邻小区的干扰。
在本申请的一些实施例中,本申请实施例提供的功率控制方法,除了执行前述步骤之外,还可以包括如下步骤:
B1、网络设备向终端设备发送第四信息,第四信息包括:第一数值M,其中,第四信息用于指示至少M个相邻小区的参考信号接收功率大于第二参考信号接收功率门限时终端设备发送上行信号的发射功率不能超过第一功率值。
其中,网络设备还可以发送第四信息,网络设备通过第四信息向终端设备发送第一数值M,网络设备可以向终端设备指示M,M是终端设备的相邻小区的参考信号接收功率大于第二参考信号接收功率门限的相邻小区个数,即网络设备还可以要求终端设备统计终端设备的相邻小区的参考信号接收功率大于第二参考信号接收功率门限的相邻小区个数,因此当终端设备的服务小区的参考信号接收功率大于第一参考信号接收功率门限、且至少M个相邻小区的参考信号接收功率大于第二参考信号接收功率门限时,终端设备发送上行信号 的发射功率不能超过第一功率值。或者当服务小区的参考信号接收功率大于第一参考信号接收功率门限、且至少M个相邻小区的参考信号接收功率大于第一参考信号接收功率门限时,终端设备发送上行信号的发射功率不能超过第一功率值。在实际应用中,网络设备所指示的M表示的具体数值可以根据应用场景确定,此处不做限定。
在本申请的一些实施例中,本申请实施例提供的功率控制方法,除了执行前述步骤之外,还可以包括如下步骤:
C1、网络设备向终端设备发送第五信息,第五信息包括:第二功率值,第二功率值是终端设备发送上行信号能够使用的最大发射功率值。
其中,网络设备还可以发送第五信息,网络设备通过第五信息向终端设备发送第二功率值,终端设备接收到该第五信息之后,终端设备可以确定出第二功率值,第二功率值是终端设备发送上行信号能够使用的最大发射功率值,因此终端设备发送上行信号所采用的发射功率不能超过该第二功率值,从而减少终端设备对相邻小区的上行干扰。
在本申请的一些实施例中,第一功率值小于第二功率值。其中,第二功率值可以是网络设备为服务小区下的所有终端设备规定的最大发射功率值,而第一功率值可以网络设备为特定类型的终端设备发送的最大发射功率值,例如第一功率值是网络设备为飞行器终端设备所规定的最大发射功率值,从而减少飞行器终端设备对相邻小区的上行干扰。
通过前述实施例对本申请的举例说明,网络设备向终端设备发送第一信息,和/或,网络设备向终端设备发送第二信息,其中,第一信息包括:第一参考信号接收功率门限,第二信息包括:第二参考信号接收功率门限;网络设备向终端设备发送第三信息,第三信息包括:第一功率值,第一功率值用于指示当终端设备的服务小区的参考信号接收功率大于第一参考信号接收功率门限、且终端设备的相邻小区的参考信号接收功率大于第二参考信号接收功率门限时,或当服务小区的参考信号接收功率大于第一参考信号接收功率门限、且相邻小区的参考信号接收功率大于第一参考信号接收功率门限时,终端设备发送上行信号的发射功率不能超过第一功率值。本申请实施例中,网络设备可向终端设备指示第一参考信号接收功率门限、第二参考信号接收功率门限,还可以向终端设备指示第一功率值,因此网络设备指示了终端设备的发射功率控制既考虑到与服务小区的参考信号接收功率,也考虑到与相邻小区的参考信号接收功率。只有当终端设备对相邻小区造成比较大的干扰时,才会限制终端设备允许发送的最大功率,从而减轻了对相邻小区的上行干扰。
前述实施例从网络设备侧对功率控制方法进行了举例说明,接下来从终端设备侧对功率控制方法进行举例说明,请参阅图6所示,本申请实施例提供的一种功率控制方法,包括如下步骤:
601、终端设备接收网络设备发送的第一信息,和/或,终端设备接收网络设备发送的第二信息,其中,第一信息包括:第一参考信号接收功率门限,第二信息包括:第二参考信号接收功率门限。
在本申请实施例中,网络设备可以向终端设备发送小区参考信号,终端设备对该CRS进行测量接收,从而终端设备可以生成RSRP,RSRP是终端设备接收到的小区公共参考信号的功率值,数值为测量带宽内单个资源粒子功率的线性平均值,反映的是本小区有用信号的强度。举例说明,对于LTE系统的应用场景,LTE系统下基站需要在某些符号上发送小 区参考信号,用户设备通过测量可知本小区的参考信号接收功率。
在本申请实施例中,网络设备可以通过第一信息向终端设备发送第一参考信号接收功率门限,则终端设备接收到第一信息之后,终端设备解析该第一信息可以得到第一参考信号接收功率门限,其中网络设备和终端设备之间的通信过程可以使用无线通信连接来实现,例如可以使用系统信息来承载该第一信息。同样的,网络设备还可以通过第二信息向终端设备发送第二参考信号接收功率门限,则终端设备接收到第二信息之后,终端设备解析该第二信息可以得到第二参考信号接收功率门限。
在本申请的一些实施例中,第一信息和第二信息通过同一个系统信息块传输给终端设备。如图4和图5-a所示,图4为本申请实施例提供的一种系统信息块的实现方式示意图,图5-a为本申请实施例提供的另一种系统信息块的实现方式示意图。网络设备可以将第一信息和第二信息承载在系统信息块1中,然后将系统信息块1传输给终端设备,从而终端设备接收到系统信息块1之后,终端设备可以通过该系统信息块1得到第一信息和第二信息。第一信息和第二信息通过同一个系统信息块传输给终端设备,从而提高信息发送的效率,提高对传输资源的利用率。不限定的是,在本申请的另一些实施例中,第一信息和第二信息也可以通过不同的系统信息块传输给终端设备,则网络设备可以分别传输第一信息和第二信息,从而可以采用灵活的方式各自传输,便于终端设备的接收。
在本申请的一些实施例中,第一参考信号接收功率门限小于第二参考信号接收功率门限。网络设备可以设置第一参考信号接收功率门限小于第二参考信号接收功率门限,即第二参考信号接收功率门限的门限值大于第一参考信号接收功率门限的门限值。本申请实施例中第一参考信号信号接收功率门限用于与终端设备测量到的服务小区的参考信号接收功率进行功率值比较,或者第一参考信号信号接收功率门限用于与终端设备测量到的相邻小区的参考信号接收功率进行功率值比较,第二参考信号信号接收功率门限用于与终端设备测量到的相邻小区的参考信号接收功率进行功率值比较。因此设置第二参考信号接收功率门限的门限值大于第一参考信号接收功率门限的门限值,终端设备的相邻小区的参考信号接收功率可能不超过第二参考信号接收功率门限,使得终端设备采用的上行信号的发射功率不超过后续的第一功率值,因此可以降低终端设备对相邻小区的上行干扰。
在本申请的一些实施例中,第一参考信号接收功率门限为无穷小的值,或者为负无穷大的值。其中,网络设备在确定第一参考信号接收功率门限时,网络设备可以将第一参考信号接收功率门限设置为无穷小的值或者负无穷大的值,从而该第一参考信号接收功率门限与终端设备的参考信号接收功率进行功率值比较时,该终端设备的参考信号接收功率更容易超过第一参考信号接收功率门限。举例说明,基站可以将第一参考信号接收功率门限值设置为很小的值或者设置为无穷小的值,其中很小的值所采用的数量级比较可以由基站根据具体场景来设置,此处不做限定。
602、终端设备接收网络设备发送的第三信息,第三信息包括:第一功率值。
在本申请实施例中,网络设备还可以向终端设备发送第一功率值,网络设备可以通过第三信息向终端设备发送第一功率值,终端设备接收到第三信息之后,终端设备解析该第三信息可以得到第一功率值。
603、终端设备确定服务小区的参考信号接收功率,以及终端设备确定相邻小区的参考 信号接收功率。
在本申请实施例中,终端设备不仅需要测量本服务小区的参考信号接收功率,还需要测量相邻小区的参考信号接收功率,其中终端设备对参考信号接收功率的测量可参阅现有技术,本申请实施例中需要测量的相邻小区可以由终端设备来确定。
604、当服务小区的参考信号接收功率大于第一参考信号接收功率门限、且相邻小区的参考信号接收功率大于第二参考信号接收功率门限时,终端设备确定发送上行信号的发射功率不能超过第一功率值;或,
605、当服务小区的参考信号接收功率大于第一参考信号接收功率门限、且相邻小区的参考信号接收功率大于第一参考信号接收功率门限时,终端设备确定发送上行信号的发射功率不能超过第一功率值。
在本申请实施例中,终端设备在获取到服务小区的参考信号接收功率、相邻小区的参考信号接收功率之后,基于前述获取到的第一参考信号接收功率门限和/或第二参考信号接收功率门限,终端设备可以执行如下的两种实现方式,1)、当终端设备的服务小区的参考信号接收功率大于第一参考信号接收功率门限、且终端设备的相邻小区的参考信号接收功率大于第二参考信号接收功率门限时,终端设备确定发送上行信号的发射功率不能超过第一功率值。2)当服务小区的参考信号接收功率大于第一参考信号接收功率门限、且相邻小区的参考信号接收功率大于第一参考信号接收功率门限时,终端设备确定发送上行信号的发射功率不能超过第一功率值。因此只有当终端设备对相邻小区造成比较大的干扰时,才会限制终端设备允许发送的最大发射功率,从而减轻了对邻小区的上行干扰。

D1、终端设备接收网络设备发送的第四信息,第四信息包括:第一数值M,第四信息用于指示至少M个相邻小区的参考信号接收功率大于第二参考信号接收功率门限时终端设备发送上行信号的发射功率不能超过第一功率值,或者终端设备根据预先规定至少M个相邻小区的参考信号接收功率大于所述第二参考信号接收功率门限时所述终端设备发送上行信号的发射功率不能超过所述第一功率值;
相邻小区的参考信号接收功率大于第二参考信号接收功率门限,具体为:至少M个相邻小区的参考信号接收功率大于第二参考信号接收功率门限。
其中,网络设备还可以发送第四信息,网络设备通过第四信息向终端设备发送第一数值M,网络设备可以向终端设备指示M,M是终端设备的相邻小区的参考信号接收功率大于第二参考信号接收功率门限的相邻小区个数,即网络设备还可以要求终端设备统计终端设备的相邻小区的参考信号接收功率大于第二参考信号接收功率门限的相邻小区个数,因此当终端设备的服务小区的参考信号接收功率大于第一参考信号接收功率门限、且至少M个相邻小区的参考信号接收功率大于第二参考信号接收功率门限时,终端设备发送上行信号的发射功率不能超过第一功率值。或者当服务小区的参考信号接收功率大于第一参考信号接收功率门限、且至少M个相邻小区的参考信号接收功率大于第一参考信号接收功率门限时,终端设备发送上行信号的发射功率不能超过第一功率值。在实际应用中,网络设备所指示的M表示的具体数值可以根据应用场景确定,此处不做限定。
在本申请的一些实施例中,本申请实施例提供的功率控制方法,除了执行前述步骤之外,还可以包括如下步骤:
E1、终端设备接收网络设备发送的第五信息,第五信息包括:第二功率值,第二功率值是终端设备发送上行信号能够使用的最大发射功率值。
其中,网络设备还可以发送第五信息,网络设备通过第五信息向终端设备发送第二功率值,终端设备接收到该第五信息之后,终端设备可以确定出第二功率值,第二功率值是终端设备发送上行信号能够使用的最大发射功率值,因此终端设备发送上行信号所采用的发射功率不能超过该第二功率值,从而减少终端设备对相邻小区的上行干扰。
在本申请的一些实施例中,第一功率值小于第二功率值。其中,第二功率值可以是网络设备为服务小区下的所有终端设备规定的最大发射功率值,而第一功率值可以网络设备为特定类型的终端设备发送的最大发射功率值,例如第一功率值是网络设备为飞行器终端设备所规定的最大发射功率值,从而减少飞行器终端设备对相邻小区的上行干扰。
在本申请的一些实施例中,第一参考信号接收功率门限为无穷小的值,或者为负无穷大的值。其中,网络设备在确定第一参考信号接收功率门限时,网络设备可以将第一参考信号接收功率门限设置为无穷小的值或者负无穷大的值,从而该第一参考信号接收功率门限与终端设备的参考信号接收功率进行功率值比较时,该终端设备的参考信号接收功率更容易超过第一参考信号接收功率门限。举例说明,基站可以将第一参考信号接收功率门限值设置为很小的值或者设置为无穷小的值,其中很小的值所采用的数量级比较可以由基站根据具体场景来设置,此处不做限定。
在本申请的一些实施例中,本申请实施例提供的功率控制方法,除了执行前述步骤之外,还可以包括如下步骤:
F1、当服务小区的参考信号接收功率大于第一参考信号接收功率门限、且相邻小区的参考信号接收功率小于或等于第二参考信号接收功率门限时,终端设备确定发送上行信号的发射功率不能超过第二功率值。
其中,当服务小区的参考信号接收功率大于第一参考信号接收功率门限、且相邻小区的参考信号接收功率小于或等于第二参考信号接收功率门限时,终端设备采用的上行信号的发射功率可以超过第一功率值,也可以不超过第一功率值,只需要终端设备发送上行信号的发射功率不能超过第二功率值,具体终端设备发送上行信号的发射功率的功率值不做限定。
通过前述实施例对本申请的举例说明,终端设备接收网络设备发送的第一信息,和/或,终端设备接收网络设备发送的第二信息,其中,第一信息包括:第一参考信号接收功率门限,第二信息包括:第二参考信号接收功率门限;终端设备接收网络设备发送的第三信息,第三信息包括:第一功率值;终端设备确定服务小区的参考信号接收功率,以及终端设备确定相邻小区的参考信号接收功率。当终端设备的服务小区的参考信号接收功率大于第一参考信号接收功率门限、且终端设备的相邻小区的参考信号接收功率大于第二参考信号接收功率门限时,或当服务小区的参考信号接收功率大于第一参考信号接收功率门限、且相邻小区的参考信号接收功率大于第一参考信号接收功率门限时,终端设备发送上行信号的发射功率不能超过第一功率值。本申请实施例中,网络设备可向终端设备指示第一参考信号接收功率门限、第二参考信号接收功率门限,还可以向终端设备指示第一功率值,因此网络设备指示了终端设备的发射功率控制既考虑到与服务小区的参考信号接收功率, 也考虑到与相邻小区的参考信号接收功率。只有当终端设备对相邻小区造成比较大的干扰时,才会限制终端设备允许发送的最大功率,从而减轻了对相邻小区的上行干扰。
为便于更好的理解和实施本申请实施例的上述方案,下面举例相应的应用场景来进行具体说明。
在本申请实施例中,以网络设备具体为基站、终端设备为无人机UE进行举例说明。本申请实施例中考虑无人机UE的发射功率对邻区基站的上行接收的干扰问题。若无人机UE测量的服务小区的RSRP超过服务基站设置的RSRP门限时,确定无人机UE的发射功率不能超过基站为无人机UE广播的最大发射功率。这样,无人机UE就不会对邻区基站的上行接收造成比较大的干扰。
在本申请实施例中,基站在系统信息块x中通知第一最大功率。例如,第一最大功率是p-Max-Aerial。通常第一最大功率是为空中UE(如无人机UE)发送上行信号所配置的最大发射功率。
在本申请实施例中,基站在系统信息块1中通知第二最大功率。例如,第二最大功率是p-Max。通常第二最大功率是地面UE(或非无人机UE)发送上行信号所能支持的最大发射功率。如果基站配置了第二最大功率,地面UE(或非无人机UE)发送上行信号所能支持的最大发射功率不大于第二最大功率。
举例说明,基站通知的第二最大功率值大于基站通知的第一最大功率值。
基站在系统信息块X中通知第一参考信号接收功率门限和/或第二参考信号接收功率门限,其中,前述的X=1或2。
在本申请的一些实施例中,第一参考信号接收功率门限值可以取很小的值或者取无穷小值。例如,基站在系统信息块X中通知第一参考信号接收功率门限和第二参考信号接收功率门限,但基站将第一参考信号接收功率门限值设置为很小的值或者设置为无穷小。
在本申请的一些实施例中,考虑到降低无人机UE对邻小区的上行干扰,第二参考信号接收功率门限值不能取很小的值或者不能取无穷小值。
接下来对无人机用户设备实现的一种功率控制方法进行举例说明:
步骤1、无人机用户设备通过接收系统信息块1或系统信息块2,获取服务小区通知的第二最大功率、第一最大功率、第一参考信号接收功率门限、第二参考信号接收功率门限中的一种或多种。
步骤2、无人机用户设备获取服务小区的参考信号接收功率;
步骤3、无人机用户设备获取一个或多个邻小区的参考信号接收功率;
步骤4、若上述服务小区的参考信号接收功率大于第一参考信号接收功率门限,且至少M个邻小区的参考信号接收功率大于第二参考信号接收功率门限,则无人机用户设备的发射功率不能超过基站配置的第一最大功率。其中,M是大于等于1的正整数,M的值是基站通过系统信息块X中通知给无人机用户设备的或者是系统预先规定的。
接下来对无人机用户设备实现的另一种功率控制方法进行举例说明:
步骤1、无人机用户设备通过接收系统信息块1或系统信息块2,获取服务小区通知的第二最大功率、第一最大功率、第一参考信号接收功率门限、第二参考信号接收功率门限中的一种或多种。
步骤2、无人机用户设备获取服务小区的参考信号接收功率;
步骤3、无人机用户设备获取一个或多个邻小区的参考信号接收功率;
步骤4、若上述服务小区的参考信号接收功率大于第一参考信号接收功率门限,且至少M个邻小区的参考信号接收功率大于第一参考信号接收功率门限,则无人机用户设备的发射功率不能超过基站配置的第一最大功率。其中,M是大于等于1的正整数,M的值是基站通过系统信息块X中通知给无人机用户设备的或者是系统预先规定的。
通过前述的举例说明可知,当无人机UE测量的服务小区的RSRP大于第一RSRP门限,且无人机UE测量的一个或多个邻小区的RSRP大于第二RSRP门限时,无人机UE上行传输所用的功率不能超过基站配置的最大发射功率。基站通过无线资源控制(Radio Resource Control,RRC)信令配置上述邻小区的M取值。在本申请实施例中,无人机UE的发射功率控制既考虑到与服务小区的RSRP测量结果,也考虑到与邻小区的RSRP测量结果。只有当无人机对邻小区造成比较大的干扰时,才会限制无人机允许发送的最大功率,从而减轻了对邻小区的上行干扰。
需要说明的是,对于前述的各方法实施例,为了简单描述,故将其都表述为一系列的动作组合,但是本领域技术人员应该知悉,本申请并不受所描述的动作顺序的限制,因为依据本申请,某些步骤可以采用其他顺序或者同时进行。其次,本领域技术人员也应该知悉,说明书中所描述的实施例均属于优选实施例,所涉及的动作和模块并不一定是本申请所必须的。
