具体实施方式
下面将结合附图对本申请作进一步地详细描述。
为便于理解本申请实施例，首先以图1中示出的通信系统为例详细说明适用于本申请实施例的通信系统。图1示出了适用于本申请实施例的通信方法的通信系统的示意图。如图1所示，该通信系统100包括网络设备102和通信设备106，网络设备102可配置有多个天线，终端设备也可配置有多个天线。可选地，该通信系统还可包括网络设备104，网络设备104也可配置有多个天线。
应理解，网络设备102或网络设备104还可包括与信号发送和接收相关的多个部件(例如，处理器、调制器、复用器、解调器或解复用器等)。
其中，网络设备为具有无线收发功能的设备或可设置于该设备的芯片，该设备包括但不限于：演进型节点B(evolved Node B，eNB)、无线网络控制器(radio network controller，RNC)、节点B(Node B，NB)、基站控制器(base station controller，BSC)、基站收发台(base transceiver station，BTS)、家庭基站(例如，home evolved NodeB，或home Node B，HNB)、基带单元(baseband unit，BBU)，无线保真(wireless fidelity，WIFI)系统中的接入点(access point，AP)、无线中继节点、无线回传节点、传输点(transmission and reception point，TRP或者transmission point，TP)等，还可以为5G，如，NR，系统中的gNB，或，传输点(TRP或TP)，5G系统中的基站的一个或一组(包括多个天线面板)天线面板，或者，还可以为构成gNB或传输点的网络节点，如基带单元(BBU)，或，分布式单元(DU，distributed unit)等。
在一些部署中，gNB可以包括集中式单元(centralized unit，CU)和DU。gNB还可以包括射频单元(radio unit，RU)。CU实现gNB的部分功能，DU实现gNB的部分功能，比如，CU实现无线资源控制(radio resource control，RRC)，分组数据汇聚层协议(packet data convergence protocol，PDCP)层的功能，DU实现无线链路控制(radio link control，RLC)、媒体接入控制(media access control，MAC)和物理(physical，PHY)层的功能。由于RRC层的信息最终会变成PHY层的信息，或者，由PHY层的信息转变而来，因而，在这种架构下，高层信令，如RRC层信令或PHCP层信令，也可以认为是由DU发送的，或者，由DU+RU发送的。可以理解的是，网络设备可以为CU节点、或DU节点、或包括CU节点和DU节点的设备。此外，CU可以划分为接入网RAN中的网络设备，也可以将CU划分为核心网CN中的网络设备，在此不做限制。
通信设备也可以称为用户设备(user equipment，UE)、接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。本申请的实施例中的终端设备可以是手机(mobile phone)、平板电脑 (Pad)、带无线收发功能的电脑、虚拟现实(virtual reality，VR)终端设备、增强现实(augmented reality，AR)终端设备、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程医疗(remote medical)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端等等。本申请的实施例对应用场景不做限定。为便于描述，本申请下文中将前述通信端设备及可设置于前述通信设备的芯片统称为终端设备。
在该通信系统100中，网络设备102和网络设备104均可以与多个终端设备(例如图中示出的终端设备106)通信。网络设备102和网络设备104可以与类似于终端设备106的任意数目的终端设备通信。但应理解，与网络设备102通信的终端设备和与网络设备104通信的终端设备可以是相同的，也可以是不同的。图1中示出的终端设备106可同时与网络设备102和网络设备104通信，但这仅示出了一种可能的场景，在某些场景中，终端设备可能仅与网络设备102或网络设备104通信，本申请对此不做限定。
应理解，图1仅为便于理解而示例的简化示意图，该通信系统中还可以包括其他网络设备或者还可以包括其他终端设备，图1中未予以画出。
本申请实施例提供了一种功率控制方法，为了提高系统性能，链路自适应、功率控制等常常是通信系统中重要的管理功能。在通信网络中，至少一个节点向其他节点发送信号，而功率控制的目的，是使得网络中，由至少一个节点发送的信号，到达其他节点的时候，功率能够满足系统的需求。
这里的节点，可以是指基站、用户设备等等。如，功率控制可以是，使得一个用户发送的信号功率，在到达另一个用户的时候，满足一定的功率要求。或者如，功率控制可以是，使得用户发送的信号功率，在到达基站的时候，满足基站的功率要求。或者如，可以通过功率控制，使得基站发送的信号，到达用户设备的时候，满足用户设备的功率需求。
功率控制中的功率需求，可以是指到达一个节点的功率需求，如，若信号对该节点是有用信号，则该节点对接收信号的功率有需要满足解调门限的需求，该需求为接收信号的功率应不能太低，否则导致无法正确接收、解调。或者，如，若该信号对该节点是非有用信号，如为干扰信号，则该节点对该接收信号的功率有需要满足干扰门限值的需求，该需求为该接收信号的功率应不能太高，否则导致该信号对该节点的有用信号造成较强的干扰。
功率控制可以发生在一个节点与另一个节点之间，如D2D场景为了一个用户设备到另一个用户设备的功率满足一定的信号干扰噪声比(signal to interference plus noise ratio，SINR)；也可以发生在多个节点与一个节点之间，如LTE中的上行，功率控制是为了让网络中的至少一个用户设备，到达基站的功率，满足基站的信号干扰噪声比SINR需求；也可以发生在多个节点到多个节点之间，如在时分双工(time division duplex，TDD)网络制式中，系统中可能同时存在上行和下行调度(如5G网络中的动态TDD技术)，此时功率控制可以用来关系网络中的多个用户设备、多个基站的多对多的功率要求。
功率控制的设计，是控制网络中节点的信号发送功率，使得该信号的接收功率，满足接收要求。这里，接收要求可以是上文所述的功率要求、SINR要求等，或者是信噪比(singal-noise ratio，SNR)要求。SNR、SINR、IoT(interference over thermal，干扰比热)、RSRP(reference signal received power，参考信号接收功率)、信号的接收功率等，都可以 看成是功率控制环节中的目标参数，这些参数不完全等价，但是是互相联系的。如，SINR和RSRP不完全相等，但在干扰水平相同的情况下，RSRP越高，意味着信号的SINR越好。本文中的功率控制，并不限定实际中算法的目标控制参数。
本申请实施例提供的功率控制方法适用于引入双连接技术的通信系统。所谓双连接技术其实就是在非理想后向回程前提下的载波聚合，指的是一个终端可以同时连接到两个通过非理想后向回程相连的基站进行数据通讯。其中，典型的场景是有一个基站是宏蜂窝，另外一个基站是小蜂窝。宏蜂窝和小蜂窝通过标准的X2接口相连。R10的载波聚合中多个载波的调度都是由一个调度器来完成的；而在双连接中，宏蜂窝和小蜂窝的调度器分别管理各自基站上的无线资源，所以需要相互之间进行协调。这是从系统架构的角度来说明双连接和载波聚合之间的本质差别。双连接技术与载波聚合技术相比的一个优点是允许宏蜂窝和小蜂窝在系统时间上不同步。
图2是双连接的控制面架构拓扑图。其中，201为MeNB，MeNB表示宏蜂窝，202为SeNB，SeNB表示小蜂窝，203为MME，MME是核心网的移动控制实体。终端、MeNB和MME203之间的信令连接和当时的现有系统相比没有发生变化，也就是说一个终端只有一个无线资源控制信令(RRC)链路和一个S1信令链路。SeNB和MeNB之间依旧通过X2接口相连。
在图2中的MeNB和SeNB上可以分别配置载波聚合。为了做一进步的区分，MeNB上所有配置的服务载波称为主小区群组(MCG，Master Cell Group)，SeNB上所有配置的服务载波称为辅小区群组(SCG，Secondary Cell Group)。双连接技术允许终端设备同时分别与MCG(master cell group)和SCG(sencondary cell group)建立连接，这样能够提高单用户的吞吐量。在双连接场景，所述主小区群组也可以由多于一个基站配置，所述辅小区群组也可以由多于一个基站配置。
对于LTE与LTE的双连接模式，上行控制信息(Channel Quality Indicator，UCI)可以通过MCG中的PUCCH和SCG中的PUCCH共同发送。DC由于允许MCG与SCG在系统时间上是不同步的，那么，在MeNB和SeNB调度下的不同小区的子帧在传输过程中就存在资源重叠问题，所谓资源重叠指的是MCG与SCG的时域资源重叠，目前协议规定，MCG与SCG各自有配置有最大功率P MeNB与P SeNB，MCG中各载波的总功率不能超过P MeNB，同样，SCG中各载波的总功率不能超过P SeNB，且P MeNB与P SeNB的和不能超过所有载波的最大功率P cmax。网络侧的MeNB和SeNB上对每个终端设备上的配置功率通过γ MCG和γ SCG来进行分配，γ MCG和γ SCG为百分比值，即用P cmax乘以γ MCG和P cmax乘以γ sCG，就可以得到双连接模式下基站对每个终端设备在每个小区上的功率配置值。
因为LTE与LTE的双连接模式下UE是通过网络侧配置的最大允许发送功率P emax，自身的最大允许发送功率P powerclass来计算P cmax_MeNB和P cmax_SeNB，然后再通过P cmax_MeNB和P cmax_SeNB计算P cmax_dc,最终通过γMCG和γSCG参数，用P cmax乘以γ MCG和P cmax乘以γ sCG，得到双连接模式下基站对每个终端设备在每个小区群组上的功率配置值。
对于E-UTRAN与LTE的双连接模式(简称为EN-DC模式)，考虑到网络的演进步骤，目前默认E-UTRAN为主小区群组，NR为辅小区群组，目前标准将动态功率共享定义成一种能力，具备动态功率共享能力的终端类型为第一类型终端，不具备相应能力的为第二类型终端，这里可以理解为第二类型终端能够支持半静态的功率共享。在EN-DC模式下，所述主小区群组也可以由NR作为主小区群组，所述辅小区群组也可以由LTE作为辅小区 群组。
其中，具备动态功率共享的第一类型终端的通信行为可通过图3来描述，具体流程为：
步骤a1，终端设备向网络侧上报自身支持具备动态功率共享的能力；
步骤b1，终端设备获取网络下发的配置功率值，通过计算得到P CMAX_LTE、P CMAX__NR和P CMAX__ENDC。
步骤c1，终端设备以NR时隙长度为时间单元对各LTE和NR物理信道上的实时功率的总和是否大于P CMAX__ENDC进行判断，如果超过P CMAX__ENDC，EN-DC模式下UE将对NR侧进行发射功率调整或不在NR进行上行功率发射。
其中，不具备动态功率共享的第二类型终端的通信行为可通过图4来描述，具体流程为：
步骤a2，终端设备向网络侧上报自身不支持具备动态功率共享的能力；
步骤b2，终端设备获取网络下发的配置功率值，通过计算得到P CMAX_LTE、P CMAX__NR和P CMAX__ENDC。
步骤c2，终端设备判断半静态功率配置值P CMAX_LTE和P CMAX__NR的总和是否大于P CMAX__ENDC进行判断，终端可以根据当前的网络配置情况按照单发的方式进行。
而目前5G标准定义EN-DC模式下，网络侧为终端设备分别在MCG和SCG配置了最大允许发送功率绝对值，假设分别称为P _LTE和P _NR。由于E-UTRAN和NR为两种不同的制式，因此P CMAX_LTE和P CMAX_NR，以及P CMAX_ENDC需要重新根据P _LTE和P _NR以及其它相关参数例如P EMAX、P powerclass计算。
基于上述概念，本申请实施例进一步对功率控制方法的具体过程进行详细说明，具体步骤如图5所示。
步骤501，通信设备接收网络侧配置的第一功率值，该第一功率值指的是网络侧为通信设备配置的小区群组的最大允许发送功率值。
步骤502，通信设备根据所述第一功率值，确定所述通信设备在该小区群组上的第一保证功率值。
具体地，在上述步骤中，小区群组可以指的是上文中的MCG或者是SCG，针对EN_DC模式，小区群组是MCG时，该小区群组为一个LTE小区或者多个LTE小区；小区群组是SCG时，该小区群组为一个或者多个NR小区。另外，小区群组是MCG时，该第一功率可以指的是P _LTE，第一保证功率值可以指的是通信设备在MCG上配置的最大发送功率P CMAX_LTE，第一保证功率值可以指的是通信设备在一个LTE小区上配置的最大发送功率P CMAX_LTE_L,c，小区群组是SCG时，该第一功率可以指的是P _NR，第一保证功率值可以指的是通信设备在SCG上配置的最大发送功率P CMAX_NR，对于NR而言，一个小区中可能存在两个上行载波，即包括上行载波和补充上行载波，因此第一功率保证值可以为上行载波上的定义，也可以为补充上行载波上的定义。其中，第一保证功率值在一个取值区间内，也就是说，第一保证功率值的取值位于下限P CMAX_L和上限P CMAX_H之间。
本申请实施例中，P _LTE和P _NR是在EN-DC模式下，网络侧为通信设备单独配置的功率配置值，那么对于通信设备而言必须考虑P _LTE值对P CMAX_LTE或P CMAX_NR的影响。 P CMAX_LTE或P CMAX_NR是功率控制过程中功率发射上限取值，在EN-DC模式下，LTE或NR侧的上限功率将P_LTE和P_NR代入运算，能够实现对功率的独立半静态调整，且满足EN-DC的网络配置需求。
具体来说，在步骤102中，所述通信设备根据所述第一功率值，以及以下功率值中的至少一项：第三功率值和第四功率值，确定出最小功率值；
所述通信设备将所述最小功率值作为所述通信设备在所述小区群组上的第一保证功率值；
其中，所述第三功率值是所述网络侧配置给所述通信设备的最大允许发送功率值，也就是P EMAX,c，所述第四功率值是所述通信设备的最大允许发送功率值，也就是P powerclass。
也就是说，针对EN-DC模式中的LTE小区，终端设备通过P EMAX,c和所述通信设备在LTE小区群组上的最大允许发送功率值P powerclass_LTE，以及网络侧配置的P _LTE，计算得到终端设备在LTE小区中的第一保证功率P CMAX_LTE，计算方式可以如公式[1]、公式[2]和公式[3]所示。
P CMAX_LTE_L,c≤P CMAX_LTE,c≤P CMAX_LTE_H,c     ……公式[1]
P CMAX_LTE_L,c＝MIN{P EMAX,c-T c,c,(P powerclass_LTE-ΔP powerclass_LTE)-
MAX(MPR c+A-MPR c+ΔT IB,c+ΔT c,c+ΔT ProSe,p-MPR c),P _LTE-ΔT c,c}  …公式[2]
P CMAX_LTE_H,c＝MIN{P EMAX,c,P powerclass_LTE-ΔP powerclass_LTE,P _LTE}      ……公式[3]
其中，公式[1]中P CMAX_LTE,c为终端设备在一个LTE小区中的配置功率，P CMAX_LTE,c的下限值为P CMAX_LTE_L,c，P CMAX_LTE,c的上限值为P CMAX_LTE_H,c。公式[2]和公式[3]中，P EMAX,c是网络侧通过RRC信令配置给终端的最大允许发射功率值，P powerclass_LTE是终端设备在LTE小区群组自身能够实现的最大允许发射功率值。ΔP powerclass_LTE是针对一种功率等级终端设备在某些情况下的功率调整值，MPRc是最大功率回退值，这是多重射频指标的要求下在不同带宽和RB分配下的功率回退值，A-MPR c是附加功率回退值，在某些网络信令下可以在MPR回退基础上再进一步回退的功率值，p-MPR c是考虑特定吸收率(Specific Absorption Rate)的达标而定义的功率回退值，ΔT IB,c是考虑载波聚合情况下的发射功率放松，ΔT c,c是频带边缘处的发射功率放松，ΔT ProSe是LTE支持近距离通信业务(ProSe:Proximity sevice)的发射功率放松(例如LTE的D2D业务)。
同理，针对EN-DC模式中的NR小区，终端设备通过P EMAX,c和所述通信设备在NR小区群组上的最大允许发送功率值，以及网络侧配置的P _NR，计算得到终端设备在NR小区中的第一保证功率P CMAX_NR，计算方式可以如公式[4]、公式[5]和公式[6]所示。
P CMAX_L,f,c≤P CMAX_NR,f,c≤P CMAX_H,f,c       ……公式[4]
P CMAX_L,f,c＝MIN{P EMAX,c-Δ,(P powerclass_NR-ΔP powerclass_NR)-
MAX(MPR c+A-MPR c+ΔT IB,c+ΔT c,c,P-MPR c),P _NR-ΔT c,c}
                  ……公式[5]
P CMAX_H,f,c＝MIN{P EMAX,c,P powerclass_NR-ΔP powerclass_NR,P _NR}       ……公式[6]
其中，公式[4]中P CMAX_NR,f,c为终端设备在一个NR小区中的某个上行载波上的配置功率，P CMAX_NR,f,c的下限值为P CMAX_L,f,c，P CMAX_NR,f,c的上限值为P CMAX_H,f,c，P powerclass_NR是终端设备在NR小区群组中自身能够实现的最大允许发射功率值。MPRc是最大功率回退值，这是多重射频指标的要求下在不同带宽和RB分配下的功率回退值，A-MPR c是附加功率回退值，在某些网络信令下可以在MPR回退基础上再进一步回退的功率值，p-MPR c是考虑特定吸收率(Specific Absorption Rate)的达标而定义的功率回退值，ΔT IB,c是考虑载波聚合情况下和双连接情况下的发射功率放松，ΔT c,c是频带边缘处的发射功率放松，其余参数与公式[[1]、公式[2]和公式[3]中的参数定义一致。
基于上述公式计算得到的P CMAX_LTE和P CMAX_NR，所述通信设备根据所述第一功率值和所述第二功率值，确定所述通信设备在所述第一小区群组和所述第二小区群组资源重叠时的总保证功率值。因为针对EN-DC模式，目前默认E-UTRAN为主基站，NR为辅基站，所以第一小区群组可以理解为MCG，第二小区群组可以理解为SCG。也就是说，终端设备再通过P CMAX_LTE和P CMAX_NR的值去计算EN_DC模式下的总发送功率值P CMAX_ENDC的值，具体过程，如图6所示，包括如下步骤。
步骤601，通信设备接收网络侧配置的第一功率值和第二功率值。
步骤602，所述通信设备根据所述第一功率值和所述第二功率值，确定所述通信设备在所述第一小区群组和所述第二小区群组资源重叠时的总保证功率值。
具体来说，所述通信设备根据所述第一功率值与所述第二功率值的和值、以及以下功率值中的至少一项：所述第一保证功率值与所述第二保证功率值的和值、所述第四功率值和所述第五功率值中的最大功率值，确定出最小功率值；
所述通信设备将所述最小功率值作为所述通信设备在所述第一小区群组和所述第二小区群组重叠时的总保证功率值；
其中，所述第四功率值是所述通信设备在所述第一小区群组上的最大允许发送功率值，也就是P powerclass_LTE，所述第五功率值是所述通信设备在所述第二小区群组上的最大允许发送功率值，也就是P powerclass_NR。
本申请实施例中，在总保证功率值的计算过程中考虑P _LTE和P _NR，首先可以保证在EN-DC下的功率控制过程，对于支持动态功率共享的通信设备，在每一个所述时间单元上都能够保证动态的功率之和不会超过EN-DC下的两个小区群组下的功率配置值P _LTE和P _NR的总和。另外，这种方法也给了基站多一层的功率调整的自由度，使得EN-DC UE的功率控制过程更加灵活。
对于EN-DC双连接模式下的子帧交叠，一个LTE子帧可能和NR的多个时隙交叠。主要是因为NR根据子载波间隔的取值不同，使得时隙长度有所不同。例如，对于如图7所示的子帧交叠示意图，对于LTE第P子帧与NR的第q时隙的交叠部分的总功率值P CMAX_ENDC(p,q)，终端设备可以通过P CMAX_LTE、P CMAX_NR和P powerclass_LTE、P powerclass_NR，以及网络侧配置的P_LTE、P_NR计算得到，其中P CMAX_ENDC(p,q)取值位于下限P CMAX_ENDC_L(p,q)和上限P CMAX_ENDC_H(p,q)之间，计算方式可以如公式[7]、公式[8]和公式[9]所示。
P powerclass_ENDC＝MAX{P powerclass_LTE,P powerclass_NR}         ……公式[7]
Figure PCTCN2019074646-appb-000001
Figure PCTCN2019074646-appb-000002
其中，公式[1]中P powerclass_ENDC为P powerclass_LTE与P powerclass_NR中的最大功率值，公式[2]中P CMAX_L,c(1)1(p)为所述通信设备在MCG上的第p子帧时的第一保证功率值的下限值，P CMAX_L,c(2)2(q)为所述通信设备在SCG的第q时隙时的第二保证功率值的下限值，P CMAX_ENDC_L,c为所述通信设备的总保证功率值的下限值，公式[3]中P CMAX_H,c(1)1(p)为所述通信设备在MCG的第p子帧时的第一保证功率值的上限值，P CMAX_H,c(2)2(q)为所述通信设备在SCG的第q时隙时的第二保证功率值的上限值，P CMAX_ENDC_H,c为所述通信设备的总保证功率值的上限值。
换句话说，终端设备通过P cmax_LTE+P cmax_NR、P powerclass_ENDC、P _LTE+P _NR三项的值取最小功率值，将最小功率值作为P CMAX_ENDC。
从图7中可见，假设LTE的第P子帧还与NR的第q+1时隙直至第q+n时隙交叠，按照公式[10]可以依次计算出P CMAX_ENDC_L,c(p,q+1)、P CMAX_ENDC_L,c(p,q+2)、…、P CMAX_ENDC_L,c(p,q+n)共N+1个总保证功率值，公式[10]如下。
Figure PCTCN2019074646-appb-000003
其中，P CMAX,c(1)1(p)为所述通信设备在第一小区群组的第p子帧时的第一保证功率值，P CMAX,c(2)2(i)为所述通信设备在第二小区群组的第i时隙时的第二保证功率值，P powerclass_ENDC为所述第四功率值和所述第五功率值中的最大功率值，p _LTE+p _NR为所述第一功率值与所述第二功率值的和值，P CMAX(p,i)为所述通信设备在第i时隙的最大允许发送功率值，i的取值从q至q+n。
进一步地，终端设备基于P CMAX_ENDC,c(p,q+1)、P CMAX_ENDC,c(p,q+2)、…、P CMAX_ENDC,c(p,q+n)等，确定出实际总保证功率值的上下限，计算方式可以如公式[11]和公式[12]所示。
P' CMAX_ENDC_L,c(p,q)＝MIN{P CMAX_ENDC_L,c(p,q),P CMAX_ENDC_L,c(p,q+1),...,
