背景技术

MCG中的主基站负责MCG的调度,SCG中的辅基站负责SCG的调度,由于MCG和SCG是两个独立的调度器调度,可能由于信息交互的不及时导致都想过多的使用终端的发射功率,导致MCG的发射功率和SCG的发射功率之和大于终端的最大发射功率,从而需要对MCG或SCG的发射功率进行缩放(即减小MCG或SCG发射功率)。例如MCG的主基站可能需要使用最大发射功率,SCG的辅基站由于信息交互不及时也可能需要使用最大发射功率,从而导致MCG、SCG中上行信道需要进行功率缩放或丢弃某些载波上的信道。若单独定义MCG优先级高,可能导致SCG的所有载波上的上行发射功率都被缩放到0,影响SCG上的传输性能。

下面对本申请中所涉及到的一些通信术语进行解释说明,可以理解的是,该通信术语也是作为本申请的发明内容的一部分。
一、主小区组(MCG)、辅小区组(SCG)
一个主小区组包括一个主小区(primary cell),可选的,一个主小区组还可以包括一个或多个辅小区(secondary cell,Scell)。一个辅小区组包括一个主辅小区(Primary Secondary  Cell,Primary Scell),可选的,一个辅小区组还可以包括一个或多个辅小区(secondary cell,Scell)。
一个小区可以对应一个载波,因此,也可以称为,一个主小区组包括一个主载波,可选的,一个主小区组还可以包括一个或多个辅载波。一个辅小区组包括一个主辅载波,可选的,一个辅小区组还可以包括一个或多个辅载波。
二、CA功率分配及缩放
对于Sub6G(6GHz载波及以下),1个载波的最大带宽为100MHz,above6GHz((6GHz载波以上))的1个载波最大带宽为400MHz。为了进一步提升终端的吞吐量,终端需要使用更多的带宽。CA技术把多个连续或不连续的频谱聚合使用,从技术上解决了移动通信对于大带宽的需求,同时也提高了无线频带中零散频谱的利用率。
终端在一个载波上传输某种信道/信号时,如物理随机接入信道(Physical Random Access Channel,PRACH)、物理上行控制信道(Physical Uplink Control Channel,PUCCH)、物理上行共享信道(Physical Uplink Shared CHannel,PUSCH)、探测参考信号(Sounding Reference Signal,SRS),需要以一定的功率传输才能使得接入网设备能够正确解析到该信道或信号。当终端在多个载波上都需要进行上行传输时,在每个载波上独立计算各自信道/信号传输时所需要使用的发射功率(使用对数值表示),然后将使用对数值表示的各个载波的发射功率换算成线性值之后相加,若相加的结果大于终端的最大发射功率(Pcmax)(使用线性值表示)时,则终端需要在CA的多个载波上进行功率缩放,使能终端发射的功率小于或等于Pcmax。
三、同步DC、异步DC
同步DC指的是终端在主小区和主辅小区的下行最大接收定时偏差小于等于一个定时偏差值,该定时偏差值例如可以是35.21微秒(us)。
异步DC指的是终端在主小区和主辅小区的下行最大接收定时偏差大于一个定时偏差值,且小于主小区和辅小区中较大子载波间隔对应的半个时隙长度,该定时偏差值例如可以是35.21us。
为解决背景技术中的问题,本申请提供一种通信方法,该方法可以对MCG和SCG的发射功率进行控制,以实现MCG的发射功率与SCG的发射功率之和不大于终端的最大发射功率。
可以理解的是,本申请方法可适用于FR1(sub6GHz)+FR1(sub6GHz)的DC,即MCG和SCG中的载波的频率均低于6GHz,也可适用于FR2(above6GHz)+FR2(above6GHz)的DC,即MCG和SCG中的载波的频率均高于6GHz。
可以理解的是,本申请方法中的通信设备,可以是图1中的终端,也可以是图1中的接入网设备。比如,通信设备为终端,当终端在向接入网设备发送信道和/或数据时,可以实施本申请的通信方法。再比如,通信设备为接入网设备,当接入网设备在向终端或其他接入网设备发送信道和/或数据时,可以实施本申请的通信方法。
基于图1所示的架构,本申请提供一种通信方法,如图2所示,该方法包括以下步骤:
步骤201,通信设备根据在第一时间单元内、在第一小区组的第一发射功率和在第二时间单元内、在第二小区组的第一发射功率,确定在第一时间单元内、在第一小区组的第二发射功率和在第二时间单元内、在第二小区组的第二发射功率。
通信设备在第一时间单元内、在第一小区组的第一发射功率和在第二时间单元内、在 第二小区组的第一发射功率之和大于通信设备的最大发射功率。
第一小区组为MCG,第二小区组为SCG。或者,第一小区组为SCG,第二小区组为MCG。可以理解的是,本申请对于第一小区组的数量、第二小区组的数量不做限定。为便于说明,以一个第一小区组和一个第二小区组为例进行说明。
第一时间单元包括第一小区组对应的第一时间区间内的与第二小区组对应的第二时间区间重叠的时间单元,第二时间单元包括第二小区组对应的第二时间区间内的与第一小区组对应的第一时间区间重叠的时间单元。通信设备在第二时间单元内、在第二小区组的第一发射功率与通信设备在第三时间单元、在第二小区组内的第三发射功率不同,第三时间单元为第二小区组对应的第三时间区间内的与第一小区组对应的第一时间区间重叠的时间单元。
步骤202,通信设备根据在第一时间单元内、在第一小区组的第二发射功率,在第一时间单元内、在第一小区组发送信道和/或信号,以及,根据在第二时间单元内、在第二小区组的第二发射功率,在第二时间单元内、在第二小区组发送信道和/或信号。
基于上述方案,若通信设备在第一时间单元内、在第一小区组的第一发射功率和在第二时间单元内、在第二小区组的第一发射功率之和大于通信设备的最大发射功率,则通信设备进行功率控制,得到通信设备在第一时间单元内、在第一小区组的第二发射功率和在第二时间单元内、在第二小区组的第二发射功率,然后根据通信设备在第一时间单元内、在第一小区组的第二发射功率,在第一时间单元内、在第一小区组发送信道和/或信号,以及根据通信设备在第二时间单元内、在第二小区组的第二发射功率,在第二时间单元内、在第二小区组发送信道和/或信号,有助于提升通信设备的通信效率。
可以理解的是,本申请将通信设备的最大功率划分为第一小区组的保证功率(configured power)、第二小区组的保证功率和剩余功率(remaining power)。即第一小区组的保证功率、第二小区组的保证功率及剩余功率之和等于通信设备的最大功率。如图3所示,为功率划分示意图。其中,第一小区组的保证功率优先满足第一小区组、第二小区组的保证功率优先满足第二小区组。
其中,第一小区组的保证功率、第二小区组的保证功率及剩余功率可以是预先配置的,比如是预定义的,或者是由其他设备配置给该通信设备。例如,当通信设备为终端,则终端可以从接入网设备接收第一小区组的保证功率的信息和第二小区组的保证功率的信息。比如,在一种实现方式中,接入网设备通过无线资源控制(radio resource control,RRC)信令指示终端的最大发射功率(Pcmax)的百分比,实现向终端配置第一小区组的保证功率和第二小区组的保证功率。例如,RRC信令中的第一小区组的保证功率的信息可以是以下百分比中的一个:{0%,5%,10%,15%,20%,37%,44%,50%,56%,63%,70%,80%,90%,95%,100%},RRC信令中的第二小区组的保证功率的信息可以是以下百分比中的一个:{0%,5%,10%,15%,20%,37%,44%,50%,56%,63%,70%,80%,90%,95%,100%},从而终端可以根据百分比确定第一小区组的保证功率和第二小区组的保证功率。
下面结合示例说明。比如,接入网通过RRC信令向终端(即通信设备)发送:10%,20%,则终端可以确定第一小区组的保证功率等于Pcmax*10%,第二小区组的保证功率等于Pcmax*20%,以及确定剩余功率等于Pcmax*70%。再比如,接入网通过RRC信令向终端(即通信设备)发送:100%,0%,则终端可以确定第一小区组的保证功率等于Pcmax, 第二小区组的保证功率等于0,以及确定剩余功率等于0,等等。可以理解的是,本申请中的Pcmax表示终端的最大发射功率的线性值。
上述步骤201中,当通信设备需要在第一时间单元内、在第一小区组发射信道和/或信号,以及需要在第二时间单元内、第二小区组发射信道和/或信号,并且通信设备在第一时间单元内、在第一小区组的第一发射功率与通信设备在第二时间单元内、在第二小区组的第一发射功率之和大于通信设备的最大发射功率,则通信设备需要做功率控制,确定通信设备在第一时间单元内、在第一小区组的第二发射功率和在第二时间单元内、在第二小区组的第二发射功率,并且通信设备在第一时间单元内、在第一小区组的第二发射功率与在第二时间单元内、在第二小区组的第二发射功率之和小于或等于通信设备的最大发射功率,即不超过通信设备的最大发射功率。
为方便说明,本申请后续将第一小区组、第二小区组分别称为CG1、CG2。将第一时间区间、第二时间区间、第三时间区间分别称为T1、T2、T3,将第一时间单元、第二时间单元、第三时间单元、第四时间单元分别称为E1、E2、E3、E4。将第一小区组的保证功率、第二小区组的保证功率、剩余功率分别称为Pc1、Pc2、Pr。将通信设备的最大发射功率称为Pcmax。
进一步的,本申请做以下定义:Pijk表示通信设备在时间单元i内、在小区组j的第k发射功率。
因此,P111表示通信设备在第一时间单元内、在第一小区组的第一发射功率,P112表示通信设备在第一时间单元内、在第一小区组的第二发射功率。其中,P111也可以称为通信设备在第一时间单元内、在第一小区组的初始发射功率(或功率控制前的发射功率),P112也可以称为通信设备在第一时间单元内、在第一小区组的功率控制后的发射功率。
P221表示通信设备在第二时间单元内、在第二小区组的第一发射功率,P222表示通信设备在第二时间单元内、在第二小区组的第二发射功率。其中,P221也可以称为通信设备在第二时间单元内、在第二小区组的初始发射功率(或功率控制前的发射功率),P222也可以称为通信设备在第二时间单元内、在第二小区组的功率控制后的发射功率。
P323表示通信设备在第三时间单元内、在第二小区组的第三发射功率。可以理解的是,该第三发射功率指的是通信设备在第三时间单元内、在第二小区组的实际发射功率,即通信设备使用通信设备在第三时间单元内、在第二小区组的第三发射功率,在第三时间单元内、在第二小区组发送信道和/或信号。
P414表示通信设备在第四时间单元内、在第一小区组的第四发射功率。可以理解的是,该第四发射功率指的是通信设备在第四时间单元内、在第一小区组的实际发射功率,即通信设备使用通信设备在第四时间单元内、在第一小区组的第四发射功率,在第四时间单元内、在第一小区组发送信道和/或信号。
下面对上述各个时间单元的关系进行说明。E1包括CG1对应的T1内的与CG2对应的T2重叠的时间单元,E2包括CG2对应的T2内的与CG1对应的T1重叠的时间单元。因此,E1占用的时间区间与E2占用的时间是重叠的。E3包括CG2对应的T3内的与CG1对应的T1重叠的时间单元。E4包括CG1对应的T1内的与CG2对应的T3重叠的时间单元。因此,E3占用的时间区间与E4占用的时间是重叠的。可以理解的是,E1、E3是T1内的时间单元,E2、E4分别是T2和T3内的时间单元。
如图4所示,为本申请提供的时间单元、时间区间示例图。其中,CG1对应的时间区 间为T1,CG2对应的时间区间为T2和T3,并且CG1在T1内的E1上,与CG2在T2内的E2上时间重叠。并且在该重叠的时间上,通信设备在CG1的第一发射功率(即功率控制前的发射功率)与在CG2的第一发射功率(即功率控制前的发射功率)之和大于通信设备的最大发射功率,因此需要对通信设备做功率控制。进一步地,通信设备在E2内、在CG2的第一发射功率与通信设备在E3内、在CG2的第三发射功率不同,从图4可以看出,两个CG2分别在E2和E4上的发射功率不同,即CG2的发射功率在与CG1的T1重叠的不同的时间单元可以发生变化。同样的,CG1的发射功率在与CG2的T2和T3分别重叠不同的时间单元(如在E1和E4上)也可以发生变化,当然也可以不发生变化。
下面对图2实施例的步骤201的具体实现方法进行解释说明。
实现方法一,若P111>Pr+Pc1、且P221<=Pc2,则通信设备减小通信设备在第一时间单元内、在第一小区组的发射功率,以及维持通信设备在第二时间单元内、在第二小区组的发射功率,使得P222=P221,P112+P222<=Pcmax。
该方案中,CG1可以使用CG2的保证功率中未被CG2使用的功率,因此CG1的发射功率至多是Pc1+Pr+Pc2。同样的,CG2也可以使用CG1的保证功率中未被CG1使用的功率,因此CG2的发射功率至多也是Pc1+Pr+Pc2。
下面结合示例说明。
如图5(a)所示,为本申请提供的功率控制示意图,图中以异步DC为例。可以看出,P111+P221>Pcmax,因此需要做功率控制。其中,P111>Pr+Pc1,则该实现方法一的可能的实施方式是:减小通信设备在第一时间单元内、在第一小区组的发射功率,以及维持通信设备在第二时间单元内、在第二小区组的发射功率。参考图5(a),通信设备在第一时间单元内、在第一小区组的发射功率从P111减小为P112,通信设备在第二时间单元内、在第二小区组的发射功率维持不变(即P222=P221)。并且,功率控制后,P112+P222<=Pcmax。从而,在功率控制后,通信设备在第一时间单元内、在第一小区组的发射功率(即P112)与通信设备在第二时间单元内、在第二小区组的发射功率(即P222)之和不超过Pcmax,实现了功率控制,有助于实现正确通信。
如图5(b)所示,为本申请提供的功率控制示意图,图中以同步DC为例。其实现方法与图5(a)所示的功率控制的方法类似,可参考前述示例的描述。
可以理解的是,针对上述图5(a)或图5(b)的示例,对于通信设备减小通信设备在第一时间单元内、在第一小区组的发射功率的方法可包括以下三种但并不限于以下三种:
方法A,通信设备减小通信设备在第一时间单元内、在第一小区组的发射功率,指的是:通信设备减小在第一时间单元内、第一小区组的PRACH的发射功率、和/或PUCCH的发射功率、和/或PUSCH的发射功率、和/或SRS的发射功率,从而得到P112。
即减小通信设备在第一时间单元内、在第一小区组的PRACH的发射功率、和/或PUCCH的发射功率、和/或PUSCH的发射功率、和/或SRS的发射功率,使能P112+P221<=Pcmax,则P222=P221。
方法B,通信设备减小通信设备在第一时间单元内、在第一小区组的发射功率,指的是:通信设备减小在第一时间单元内、第一小区组的没有传输ACK/NACK/CSI的PUSCH的发射功率、和/或SRS的发射功率,从而得到P112。
即优先减小通信设备在第一时间单元内、在第一小区组的没有传输ACK/NACK/CSI的PUSCH的发射功率、和/或SRS的发射功率,若使能P112+P221<=Pcmax,则P222=P221。 进一步的,若通信设备在第一时间单元内、在第一小区组的没有传输ACK/NACK/CSI的PUSCH的发射功率和SRS的发射功率均减小至0后,P112+P221仍然大于Pcmax,则还可以减小通信设备在第二时间单元内、在第二小区组的发射功率,则P222<P221,并且满足P112+P222<=Pcmax。
方法C,通信设备减小通信设备在第一时间单元内、在第一小区组的发射功率,指的是:通信设备减小在第一时间单元内、第一小区组的PRACH的发射功率、和/或PUCCH的发射功率、和/或传输ACK/NACK/CSI的PUSCH的发射功率,从而得到P112。
即优先减小通信设备在第一时间单元内、在第一小区组的PRACH的发射功率、和/或PUCCH的发射功率、和/或传输ACK/NACK/CSI的PUSCH的发射功率,若使能P112+P221<=Pcmax,则P222=P221。进一步的,若通信设备在第一时间单元内、在第一小区组的PRACH的发射功率、PUCCH的发射功率、传输ACK/NACK/CSI的PUSCH的发射功率均减小至0后,P112+P221仍然大于Pcmax,则还可以减小通信设备在第二时间单元内、在第二小区组的发射功率,则P222<P221,并且满足P112+P222<=Pcmax。
可以理解的是,作为一种实现方法,通信设备在计算得到通信设备在第一时间区间、在第一小区组的主载波的PRACH信道、和/或PUCCH信道、和/或传输ACK/NACK/CSI的PUSCH的第一发射功率P111_1后,若确定P111_1>Pc1+Pr,则通信设备可以直接对通信设备在第一时间区间内、在第一小区组的上述信道的发射功率进行缩放(即减少),例如可以将通信设备在第一时间区间内的上述信道的发射功率之和减小到Pc1+Pr或者减小到一个更小的值(即小于Pc1+Pr的值);若通信设备确定第一时间单元内、在第一小组的第一发射功率P111与第二时间单元内、第二小组的第一发射功率P221之和大于Pcmax,则终端可以再采用上述方法A或方法B或方法C,使能P112+P222<=Pcmax;此实现方式的理由为:终端在第一小区组的主载波的PRACH信道、和/或PUCCH信道、和/或传输ACK/NACK/CSI的PUSCH信道在第一时间区间内不会发生突变,从而有助于保证基站能够正确解调这些比较重要信息。
针对上述方法A、或方法B、或方法C,可以按照以下信道优先级,依次减小信道优先级较小的信道的发射功率,直至满足功率控制要求:
优先级1:主小区上的PRACH;
优先级2:传输ACK/NACK/SR的PUCCH;传输ACK/NACK的PUSCH;
优先级3:传输CSI的PUCCH;传输CSI的PUSCH;
优先级4:没有传输ACK/NACK/CSI的PUSCH;
优先级5:SRS;辅小区上的PRACH。
其中,信道优先级从大到小(或称为从高到低)依次为:优先级1>优先级2>优先级3>优先级4>优先级5。
其中,传输ACK/NACK/SR的PUCCH与传输ACK/NACK的PUSCH的优先级相同。SRS与辅小区上的PRACH的优先级相同。传输CSI的PUCCH与传输CSI的PUSCH的优先级相同。
实现方法二,若P111>Pr+Pc1、且P221<=Pc2,则通信设备减小通信设备在第一时间单元内、在第一小区组的发射功率,以及维持通信设备在第二时间单元内、在第二小区组的发射功率,使得P222=P221,P112<=Pc1+Pr。
该方案中,CG1始终不去抢占CG2的保证功率Pc2,即CG1的发射功率至多是Pc1+Pr。
下面结合示例说明。
如图6(a)所示,为本申请提供的功率控制示意图,图中以异步DC为例。可以看出,P111+P221>Pcmax,因此需要做功率控制。其中,P111>Pr+Pc1,则该实现方法二的具体做法是:减小通信设备在第一时间单元内、在第一小区组的发射功率,使得通信设备在第一时间单元内、在第一小区组的发射功率不大于Pr+Pc1,以及维持通信设备在第二时间单元内、在第二小区组的发射功率。参考图6(a),通信设备在第一时间单元内、在第一小区组的发射功率从P111减小为P112,通信设备在第二时间单元内、在第二小区组的发射功率维持不变(即P222=P221)。并且,P112<=Pc1+Pr。从而,在功率控制后,通信设备在第一时间单元内、在第一小区组的发射功率(即P112)与通信设备在第二时间单元内、在第二小区组的发射功率(即P222)之和不超过Pcmax,实现了功率控制,有助于实现正确通信。
如图6(b)所示,为本申请提供的功率控制示意图,图中以同步DC为例。其实现方法与图6(a)所示的功率控制的方法类似,可参考前述示例的描述。
实现方法三,若P111>Pc1、且P221>Pc2,则通信设备根据第一小区组和第二小区组的信道优先级和/或载波优先级,在Pr内进行功率控制,以确定P112和P222。
该方案中,CG1始终不去抢占CG2的保证功率Pc2,即CG1的发射功率至多是Pc1+Pr。同样的,CG2始终不去抢占CG1的保证功率Pc1,即CG2的发射功率至多是Pc2+Pr。
作为一种可能的实现方法,通信设备根据第一小区组和第二小区组的信道优先级和/或载波优先级,在Pr内进行功率控制,确定P112和P222,具体包括:
若第一小区组与第二小区组的信道优先级不同,则通信设备在Pr内进行功率控制,对第一小区组和第二小区组中信道优先级较低的信道进行功率控制,确定P112和P222,信道优先级可以参考前述描述,这里不再赘述。
若第一小区组与第二小区组的信道优先级相同,则通信设备在Pr内对第一小区组和第二小区组中载波优先级较低的小区组进行功率控制,确定P112和P222,其中,载波优先级从高到低依次为:主小区组中的主小区,辅小区组中的主辅小区,主小区组或辅小区组中的辅小区。

如图7(b)所示,为本申请提供的功率控制示意图,图中以异步DC为例。可以看出,P111+P221>Pcmax,因此需要做功率控制。其中,P111>Pc1、且P221>Pc2,则该实现方法三的具体做法是:在Pr内进行功率控制。参考图7(b),CG2的信道优先级更高,因此Pr内的功率优先分配给CG2,因此功率控制后的P112=Pc1+Pr1,P222=P221,并且Pr1=Pc2+Pr-P222。从而,在功率控制后,通信设备在第一时间单元内、在第一小区组的发射功率(即P112)与通信设备在第二时间单元内、在第二小区组的发射功率(即P222) 之和不超过Pcmax,实现了功率控制,有助于实现正确通信。
如图7(c)所示,为本申请提供的功率控制示意图,图中以同步DC为例。其实现方法与图7(a)所示的功率控制的方法类似,可参考前述示例的描述。
如图7(d)所示,为本申请提供的功率控制示意图,图中以同步DC为例。其实现方法与图7(b)所示的功率控制的方法类似,可参考前述示例的描述。
