技术领域
本申请涉及无线通信技术领域但不限于无线通信技术领域，尤其涉及一种功率控制方法、用户设备(User Equipment，UE)、基站、参数配置方法和控制方法。
背景技术
5G NR(New Radio)是正在进行的3GPP(第三代合作伙伴)的研究项目，它确定了基于正交频分复用(OFDM)的新无线空口标准，并将成为下一代移动网络的基础。作为第五代移动通信系统，NR技术需要支持空前多的不同类型的应用场景，还需要同时支持传统的频段、高频段以及波束方式，对功率控制的设计带来很大挑战。
长期演进(Long Term Evolution，LTE)技术中的功率控制与很多因素有关，如路径损耗、目标接收功率、最大发送功率、闭环功率调整量、传输的带宽、传输的速率等。LTE中上行探测信号(Sounding Reference Signal，SRS)由用户设备发送给基站并用于上行信道的探测，其发送功率控制与物理上行共享信道(Physical Uplink Shared Channel，PUSCH)的功率控制过程密切相关。NR多波束场景中的SRS不仅要继承LTE的SRS的特点，还要满足新的需求，如进行上行波束扫描。上行波束扫描过程可能有不同阶段，分别支持不同数量的发送和/或接收波束的训练，波束扫描的结果用于 确定后续PUSCH、物理上行控制信道(Physical Uplink Control Channel，PUCCH)、SRS的发送波束。同时，由于无线信道的时变特性，在数据传输过程中，UE也需要发送用于信道探测或者波束扫描的SRS。因此，在多波束场景，NR需要支持多种不同需求的SRS，对功率功率控制机制有不同的要求，如何实现功率控制一方面可以满足通信信号需求，另一方面还能实现灵活配置，是亟待解决的问题之一。

具体实施方式
为使本申请的目的、技术方案和优点更加清楚明白，下文中将结合附图对本申请的实施例进行详细说明。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互任意组合。
无线通信系统中，为了降低发送设备功耗并减少不必要的高功率发送对其他传输造成的干扰，需要对传输进行发送功率控制。通信范围的大小、通信双方的收发设备的最大发送供功率和接收灵敏度、数据的调制编码方式及速率、工作的频带、传输占用的带宽等因素都会影响发送功率。一般需要在满足接收端的接收信号质量要求的条件下，尽量使用较低的发送功率。
例如，通信节点1发送参考信号，通信节点2根据该参考信号测量节点1到节点2的路径损失(pathloss，简称为PL)。PL是用节点1的参考信号的发送功率,节点2收到的参考信号的功率。节点2假定节点2到节点1的传输信道的PL与节点1到节点2的信道的PL相同，设置发送功率使得传输到达接收端的接收功率能达到接收要求。由于PL是单方面测量的结果，因此该因素在发送功率中属于开环部分。节点2接收到传输后进行解析，根据接收的质量为节点1提供功率调整的信息，该过程属于闭环功率控制。
LTE中，基站到终端的链路是下行链路，终端到基站的链路是上行链 路。下行链路的功率由基站根据各调度UE的信道测量结果以及调度算法确定。上行链路的功率控制是开环结合闭环的方式，其中由UE测量决定的功率控制因素属于开环部分，由基站测量并反馈给UE的功率控制因素属于闭环部分。此外，还有与传输相关的特定的量，如发送速率、MCS等级、发送带宽等也会影响功率。
下面是LTE的PUSCH的发送功率计算公式，以此为例对影响功率的各个参数进行说明。PUCCH也有类似的参数和机制。
Figure PCTCN2018116277-appb-000001
上式中下标c是指小区cell，支持载波聚合(CA，Carrier Aggregation)功能的每个成员载波(CC，Component Carrier)对应1个小区cell。从上式可以看到功率计算公式中每个参数都是区分cell配置的/计算的。本文中所有的描述都是针对1个CC进行描述，因此没有专门提及cell。需要指出的是，本文的所有参数都可以扩展到多个CC上，只需要将所述的功率相关的配置和计算的参数为每个CC独立配置即可。
上行传输PUSCH的功率PPUSCH的开环部分由目标接收功率PO_PUSCH、路损量PL和路损因子α决定，其中目标接收功率分为cell级和UE级参数，都由基站决定并配置给UE；而闭环部分则是基站根据测量结果与目标的差距确定闭环功率控制调整量，以传输功率控制命令(TPC Command，Transmit Power Control Command，即DCI中针对PUSCH的δ PUSCH和针对PUCCH的δ PUCCH)的方式通知UE。UE维护一个本地的功率调整量f(i)，根据传输功率控制命令进行更新，采用上述公式达到闭环控制功率的目的。其中，i是子帧编号。ΔTF是MCS相关的功率偏移，PCMAX是UE的最大功率限制，MPUSCH是PUSCH占用的RB(资源块，resource block)个数。
LTE的cell级目标接收功率P0_nominal是区分PUSCH(半静态、动 态、MSG3)和PUCCH，分别对应不同的BLER需求。UE级目标接收功率参数P0_UE_specific也是区分以上几项进行设置，功能是为了补偿系统性偏差，如，PL估计误差、绝对输出功率设置的误差。
根据传输功率控制命令更新f(i)分为两种方式：累积式和绝对值方式，其中绝对值方式是直接用基站发送的传输功率控制命令更新UE本地的功率调整量f(i)，而累积式则由基站发送的传输功率控制命令与该UE本地的功率调整量的历史值共同确定UE本地的功率调整量f(i)。
需要注意的是，这里的f(i)代表UE本地的闭环功率调整量，在LTE中PUCCH的UE本地的闭环功率调整量记作g(i)。本文中f(i)也可以应用于PUCCH，在功率控制过程中的作用与应用于PUSCH是类似的。
5G技术引入了波束的传输方式，基站和UE都支持多波束。当工作在波束模式时，功率计算需要考虑波束的特性。本申请提出多波束方式的功率控制方法。本申请中所提及的各项参数适用于不同的信道，如PUSCH、长PUSCH、短PUSCH、PUCCH、长PUCCH、短PUCCH以及信号SRS。同类型的参数在应用于上述各个信道或者信号时，可以是独立配置的，或者是组合配置的。其中组合配置的含义是指不同的信道、信号之间可共享同样的值，由预定义的方式或者基站配置的方式确定哪些不同的信道、信号之间可以共享同样的值。

所述波束可以为一种资源(例如发端预编码，收端预编码、天线端口，天线权重矢量，天线权重矩阵等)，波束序号可以被替换为资源索引，因为波束可以与一些时频码资源进行传输上的绑定。波束也可以为一种传输(发送/接收)方式；所述的传输方式可以包括空分复用、频域/时域分集等。

以下提供一种SRS功率偏移值(Power Offset)的配置：
基站为UE配置至少一个SRS的功率偏移值集合。
每个SRS的功率偏移值集合包括至少一个SRS功率偏移值，每个SRS功率偏移值用于支持不同的场景。例如，
1)每套SS的功率偏移值包括3个值，分别用于周期的、非周期的以及非持续的SRS传输。
2)或者每套SRS功率偏移值包括2个值，分别用于不同类别的SRS传输的触发类型(SRS Transmission Given Trigger Type)。
SRS功率偏移值在SRS的功率偏移值集合中的位置与场景的对应关系是预定义的。
每个SRS的功率偏移值集合用于支持不同类别的SRS传输。例如，
1)支持2个SRS的功率偏移值集合，其中第1个集合用于支持与PUSCH共享功率控制参数的SRS的功率计算，第2个集合支持其他类型的SRS的功率计算；
2)或者支持3个SRS的功率偏移值集合，其中第1个集合用于支持与PUSCH共享功率控制参数的SRS的功率计算，第2个集合支持用于下行CSI获取的SRS的功率计算，第3个集合用于支持其他类型的SRS的功率计算；
3)或者支持6个SRS的功率偏移值集合，其中第1个集合用于支持与PUSCH共享功率控制参数的SRS的功率计算，第2个集合支持用于下行CSI获取的SRS的功率计算，第3、4、5个集合分别用于上行波束管理的U1、U2、U3类型的SRS的功率计算，第6个集合用于其他类型的SRS的功率计算；
4)或者仅支持1个SRS的功率偏移值集合，用于以上所有类型的SRS传输。
SRS的功率偏移值集合的数量大于1时，每个SRS的功率偏移值集合与SRS类别的对应关系是预定义的，或者基站指示的。
UE根据SRS发送的场景及SRS类别确定功率偏移值。
基站指示的方法包括以下之一：
1)基站配置每个SRS的功率偏移值集合与SRS类别的对应关系。例如，预定义支持的所述对应关系的映射表，基站使用RRC信息为UE配置映射表中的一项；
2)或者，基站在SRS资源集合(resource set)中指示对应的SRS的功率集合。例如，通过指示SRS的功率偏移值集合ID；
3)或者，基站在激活或者触发SRS的信息中指示对应的SRS的功率集合。例如，通过指示SRS的功率偏移值集合ID。
上述SRS的功率偏移值可以为以下方式之一：
方式一：在基站配置的目标功率cell specific部分(也叫p0-Nominal)以及UE specific部分(也叫p0-UE)功率基础上，配置多种SRS的功率偏移值集合体现上述不同场景的差异。此时，SRS的目标功率由3部分组成：cell specific部分、UE specific部分以及SRS的功率偏移值。其中，cell  specific部分和UE specific部分的目标功率可能是为SRS专门配置的值，也可能使用为PUSCH配置的值，由基站显式配置或指示，或者隐式地指示该信息。具体见后面的例子。SRS的功率偏移值是专门为SRS配置的。
方式二：在基站配置的目标功率cell specific部分(也叫p0-Nominal)的基础上，UE specific部分与SRS的功率偏移值合并配置，合并的两部分可以称为SRS功率偏移值，或者SRS的UE specific目标功率值。合并的部分还需要体现上述不同场景的差异，因此，该例子中前面所描述的SRS的功率偏移值集合可以被合并的两部分的名称代替。其中，cell specific部分目标功率可能是为SRS专门配置的值，也可能使用为PUSCH配置的值，由基站显式配置或指示，或者隐式地指示该信息。具体见后面的例子。SRS的功率偏移值(SRS的UE specific的目标功率值与前述的SRS功率偏移值的合并值)是专门为SRS配置的。
以下提供一种SRS专有的j、k、l的配置以及与SRS调度信息的对应方式：
基站为UE配置J套SRS开环功率控制参数，每套SRS开环功率控制参数包括以下至少之一：目标接收功率P0，路损补偿因子alpha。其中，J为大于等于1的整数。每套SRS开环功率控制参数用j标识，其中j为整数，并且0<＝j<J。
基站为UE配置K套SRS路损测量参数，每套SRS路损测量参数包括以下至少之一：用于路损测量的参考信号RS资源类型指示、用于路损测量的参考信号RS资源指示、多个路损测量的参考信号的路径损耗值的处理规则。。其中，K为大于等于0的整数。每套SRS路损测量参数用k标识，其中k为整数，并且0<＝k<K。
基站为UE配置L套SRS闭环功率控制参数，每套SRS闭环功率控制参数包括以下至少之一：SRS闭环功率控制标识。其中，L为大于等于0 的整数。每套SRS闭环功率控制参数用l标识，其中l为整数，并且0<l<L。
基站为UE配置至少一个SRS resource set，每个SRS resource set中包含至少一个SRS资源(SRS resource)。每个SRS资源指示SRS占用的资源，包括时域、频域、码域等参数。SRS资源与发送波束关联，该关联关系可能是由无线资源控制(RRC)消息配置，也可能是由MAC控制单元(MAC CE)消息指示，或者由物理层信令例如下行控制信息(Downlink Control Information，DCI)信息指示。
基站指示UE发送SRS，至少包括SRS资源集合和/或SRS资源的指示，该SRS对应的功率控制参数用如下方式之一确定：
方式一：配置j、k、l与SRS resource set或者SRS资源指示(SRS Resource Indication，SRI)的关系
基站配置或指示SRS开环功率控制参数与SRS资源或SRS资源集合的关联关系。
在K>0时，基站配置或指示SRS路损测量参数与SRS资源或SRS资源集合的关联关系。
在L>0时，基站配置或指示SRS闭环功率控制参数与SRS资源或SRS资源集合的关联关系。
则UE根据以上关联关系，为SRS确定计算发送功率需要的参数：SRS开环功率控制参数、SRS路损测量参数、SRS闭环功率控制参数。
方式二：在SRS resource set中分别配置j、k、l，一个SRS resource set支持1套或者多套功率控制参数
基站为UE配置的J套SRS开环功率控制参数用SRS开环功率控制参数标识区分。
基站为UE配置K套SRS路损测量参数用SRS路损测量参数标识区分。
基站为UE配置L套SRS闭环功率控制参数用SRS闭环功率控制参数标识区分。
基站在SRS资源集合中携带SRS开环功率控制参数标识、SRS路损测量参数标识、SRS闭环功率控制参数标识。UE为SRS资源集合中的所有SRS资源采用相同的参数计算发送功率。
如果SRS资源集合中的SRS资源占用了多于一个预定的时间单位，UE使用相同的参数计算发送功率，并且是统一的时刻取值。或者UE为一个SRS资源计算的发送功率应用于该SRS资源集合中所有的SRS资源，包括时域重复的SRS资源。
所述的预定的时间单位是以下之一：OFDM符号、时隙、子帧、帧，以及未来系统中的时间单位。
基站在SRS资源集合中也可以携带大于1套以下的SRS功率控制参数标识：SRS开环功率控制参数标识、SRS路损测量参数标识、SRS闭环功率控制参数标识。基站需要指示SRS功率控制参数标识与SRS资源的对应关系。每套SRS功率控制参数标识指示的一组功率控制各参数用于与其对应的SRS资源。
方式三：基站配置j、k、l的关联，用关联ID应用所述的配置，支持1个set 1套或者多套功率控制参数
基站配置SRS开环功率控制参数、SRS路损测量参数、SRS闭环功率控制参数之间的关联，并用SRS功率控制参数关联标识指示上述参数之间不同的关联关系。
基站在SRS资源集合中携带至少一个SRS功率控制参数关联标识。
当SRS功率控制参数关联标识个数为1时，UE为SRS资源集合中的所有SRS资源采用相同的参数计算发送功率。
当SRS功率控制参数关联标识个数大于1时，基站需要指示SRS功率控制参数标识与SRS资源的对应关系。每个功率控制参数关联标识指示的一组功率控制各参数用于与其对应的SRS资源。
基站在SRS resource set中，或者在触发SRS的物理层信息中为UE指 示SRS占用的RB个数。
UE通过上述方式得到SRS开环功率控制参数、SRS路损测量参数、SRS闭环功率控制参数，SRS占用的RB个数，用这些参数计算发送功率。例如，下面的式子是一种实现方式：
Figure PCTCN2018116277-appb-000002
其中，i是时间单位编号，例如，子帧号、时隙号、OFDM符号的编号等；j是SRS开环功率控制参数集合的编号，k是SRS路损测量参数集合的编号；l是SRS闭环功率控制参数集合的编号。M SRS,c(i)是SRS占用的RB个数，该参数也可能没有。SRS开环功率控制参数集合包括α SRS,c(j)和P 0_SRS,c(j)，其中P 0_SRS,c(j)由两部分组成，cell specific部分(也叫p0-Nominal)以及UE specific部分(也叫p0-UE)；PL SRS,c(k)是SRS路损测量参数；h c(i,l)是SRS闭环功率控制参数，其中l是指SRS闭环功率控制的进程标识，或者闭环功率控制loop的标识。
如何在SRS专有的j、k、l或者PUSCH的j1、k1、l1中选择NR的SRS支持不同的功能，如，波束管理(beam management)、获取上行信道状态信息(UL CSI acquisition)、获取下行信道状态信息(DL CSI acquisition)。其中波束管理的SRS还可能有不同的阶段，例如U1、U2、U3，其中U1是上行发送和接收波束的训练，U2是上行接收波束训练，U3是上行发送波束训练。其中，U1、U2、U3中训练的波束数量、波束级别可能不同。
SRS信号比较特殊，一部分SRS发送是为了进行波束训练，也就是波束管理功能的SRS，另外一部分的SRS发送是为了进行信道探测，也就是为了获取信道状态信息。前者的发送波束可能不会由基站指定，尤其是初 始阶段的波束训练，基站只为UE调度足够的资源用于发送SRS，并指示哪些资源是要求UE使用同样的发送波束，而资源与一些实施例中发送波束对应关系是UE确定的。其训练的结果被基站用于指示后续的SRS/PUSCH/PUCCH等传输的发送波束时的参考。以初始阶段的SRS作为参考，后续的SRS发送，不管是波束训练的目的还是信道探测的目的都有可能以其作为参考。
非初始阶段的波束训练分为以下情况：
情况1：依赖之前的参考SRS发送波束的
对于情况1，如果待发送的SRS与PUSCH的发送波束相同，就可以使用相同的功率控制参数以及共享相同的闭环功率控制过程；
如果待发送的SRS资源集合有多个SRS资源，其对应的发送波束集合包括PUSCH的发送波束，也可能共享PUSCH的功率控制参数和闭环功率控制过程；
如果待发送的SRS的发送波束与PUSCH的发送波束不同，但是近似相同，也就是存在特定的QCL关系，则也可能共享功率控制参数和闭环功率控制过程。
本申请所述的特定的QCL关系，是指SRS与PUSCH的发送资源至少波束资源存在一定的相似性，如方向相近。对于波束之间的关系，一般用QCL参数衡量，因此所述的特定的QCL关系是指满足特定的QCL假设，例如QCL参数中特定部分参数满足一定的门限要求，如QCL参数中的空间参数满足一定的门限要求。当对比的波束分别是上行或者下行波束时，由于发送端不同，用准共址来衡量波束相关性是不准确的，此时可以用上下行参数信号关联关系进行判断，上行(下行)参考信号的空间参数(spatial parameter)特性可以通过下行(上行)参考信号所经历信道的空间参数(spatial parameter)特性进行判定。
情况2：不依赖之前的参考SRS的发送波束的
对于情况2，由于不依赖之前的参考SRS发送波束，最好进行独立地功率控制。
对于以上各种情况，基站指示UE的发送波束与前面的用作参考的SRS的发送波束相同，但是基站可能会根据调度情况改变接收波束，因此上述情况可以是UE根据一些实施例中条件判断是否与PUSCH共享功率控制参数和闭环功率控制过程，同时也有必要支持基站指示是否与PUSCH共享功率控制参数和闭环功率控制过程。
基站为UE配置SRS专有的功率控制参数，见优选实施例2的相关描述。
基站为UE配置PUSCH的功率控制参数，描述如下：
1)基站为UE配置J1套PUSCH开环功率控制参数，每套PUSCH开环功率控制参数包括以下至少之一：PUSCH目标接收功率P0，PUSCH路损补偿因子alpha。其中，J1为大于等于1的整数；每套PUSCH开环功率控制参数用j1标识，j1为整数，并且0<＝j1<J1；
2)基站为UE配置K1套PUSCH路损测量参数，每套PUSCH路损测量参数包括以下至少之一：至少一个用于路损测量的参考信号RS资源类型指示、用于路损测量的参考信号RS资源指示、多个路损测量的参考信号的路径损耗值的处理规则。其中，K1为大于等于1的整数；每套PUSCH路损测量参数用k1标识，k1为整数，并且0<＝k1<K1；
3)基站为UE配置L1套PUSCH闭环功率控制参数，每套PUSCH闭环功率控制参数包括以下至少之一：PUSCH闭环功率控制标识。其中，L1为大于等于1的整数。每套PUSCH闭环功率控制参数用l1标识，l1为整数，并且0<＝l1<L1。
基站为UE配置至少一个SRS资源集合，每个SRS资源集合中包含至少一个SRS资源。每个SRS资源指示SRS占用的资源，包括时域、频域、 码域等参数。SRS资源集合中指示SRS资源可能是周期的、非周期的，或者半静态的。不同的SRS资源集合的调度方式可能不同。例如，周期的方式只需要RRC配置，UE在对应的位置(如时频域)发送SRS。半静态的方式需要RRC配置，并且由MAC CE激活，UE需要在激活的SRS资源集合指示的位置发送SRS。非周期的方式需要RRC配置，物理层信令触发UE在指定的位置发送SRS。非周期的方式可能还需要MAC CE激活一部分RRC配置的SRS资源集合，以减小物理层触发信令的SRS资源集合的指示开销。
基站配置或指示SRS资源与发送波束的关联关系，该关联关系可能是由RRC消息配置，也可能是由MAC CE指示，或者由物理层信令例如DCI信息指示。
基站指示UE发送SRS，可能是上述的周期的、非周期的、或者半静态的方式，UE可以确定SRS资源集合和/或SRS资源的指示，该SRS对应的功率控制参数用如下方式之一确定：
方式一：基站明确指示SRS是否共用PUSCH的功率控制
基站指示该SRS资源(集合)是否与PUSCH共享功率控制过程。
SRS资源(集合)是否与PUSCH共享功率控制过程可能是：是否共用PUSCH的开环功率控制参数、路损测量参数以及闭环功率控制过程，或者分别指示是否共用PUSCH的开环功率控制参数、路损测量参数以及闭环功率控制过程。
基站用RRC信令配置或者用MAC CE指示，或者用物理层信令指示，SRS资源(集合)是否与PUSCH共享功率控制过程。
在一些实施例中，对周期的SRS资源集合，基站使用RRC信令配置是否与PUSCH共享功率控制过程的信息；对半静态的SRS资源集合，基站可能使用RRC信令配置，或者MAC CE指示是否与PUSCH共享功率控制过程的信息；对非周期的SRS资源集合，基站使用RRC信令、或者MAC  CE，或者物理层信令指示是否与PUSCH共享功率控制过程的信息。
方式二：UE自己确定是否共用
UE根据SRS资源与发送波束的对应关系确定是否共用PUSCH的功率控制参数以及闭环功率控制过程。
如果UE确定本次SRS的发送波束参考之前发送的导频的波束资源，例如之前的SRS的发送波束，或者之前的CSI-RS的接收波束，则根据SRS发送波束与PUSCH的发送波束的关系确定是否共用PUSCH的功率控制参数以及闭环功率控制过程。
如果UE确定本次SRS的发送波束不参考任何之前发送的导频的波束资源，则SRS发送波束与PUSCH的功率控制参数无关。
对于与PUSCH共享功率控制参数以及闭环功率控制过程的SRS，确定j、k、l的方法。
不需要进一步指示的方法，用波束(beam)是否相同，或者准共位置(Quasi-Co-Location，QCL)关系判断：
当SRS资源集合中关联的发送波束数量是1时，UE通过对比SRS资源集合中关联的发送波束与PUSCH功率控制参数相关联的波束资源：
1)相同的可以共用；
2)不同但是满足特定QCL关系的可以共用；
3)不同且不满足特定QCL关系的，使用默认的一套独立配置的SRS专有功率控制资源。
当SRS资源集合中关联的发送波束数量大于1时，并且要求该多个发送波束的发送功率是一致的，则
1)SRS多个发送波束中与PUSCH功率控制参数中的关联波束中至少有一个与PUSCH的功率控制参数相关联的波束资源相同时，可以共用PUSCH中的该相同波束资源关联的参数；
2)SRS多个发送波束中与PUSCH功率控制参数中的关联波束中至少 有一个与PUSCH的功率控制参数相关联的波束资源满足特定的QCL关系时，可以共用PUSCH中的该相同波束资源关联的参数；

对于未使用波束的场景，SRS资源集合中所有SRS资源都共享PUSCH的功率控制参数。
或者，SRS资源集合根据授权类型匹配PUSCH的功率控制参数，例如grant free的PUSCH功率控制参数用于grant free的SRS资源集合，grant based的PUSCH功率控制参数用于grant freee的SRS资源集合。或者grant free的PUSCH的功率控制参数用于周期的和半静态的SRS资源集合，grant based的PUSCH的功率控制参数用于非周期的SRS资源集合。
需要进一步指示的方法：
基站指示SRS资源应用哪些PUSCH的功率控制参数。指示的方法有：
对于独立配置的SRS，确定SRS的开环功率控制参数、路损测量参数、闭环功率控制参数方法见优选实施例2。
对于SRS资源集合与PUSCH共享功率控制参数的情况，基站为SRS资源指示使用哪些PUSCH的开环功率控制参数、路损测量参数、闭环功率控制参数。
对于共享PUSCH的功率控制参数的SRS，从PUSCH的功率控制参数中得到以下参数：目标接收功率P0_PUSCH、alpha_PUSCH、PUSCH的PL测量配置、PUSCH闭环功率控制的编号，还需要根据SRS发送的场景及SRS类别确定功率偏移值，见实施例1的相关描述，最终确定SRS的发送功率。
对于共享PUSCH的功率控制参数的SRS，从PUSCH的功率控制参数 中得到以下参数：alpha_PUSCH、PUSCH的PL测量配置、PUSCH闭环功率控制的编号，还需要根据SRS发送的场景及SRS类别确定功率偏移值，该功率偏移值包含了UE specific的目标功率部分，不需要共享PUSCH的UE specific的目标功率，见实施例1的相关描述，最终确定SRS的发送功率。

Figure PCTCN2018116277-appb-000003
在一些实施例中，预先规定确定采用上述的一种方式。
在一些实施例中，基站配置或指示确定采用上述的一种方式。
此处提供SRS resource set包含default的功率控制参数配置，满足一定关系时，与PUSCH共享的实施例：
基站为UE配置至少一个SRS resource set。每个SRS resource set包含至少一个SRS resource。
对每个SRS resource set，至少配置一个功率控制参数集合。
1)当SRS resource set只包含一个功率控制参数集合时，SRS resource set中所有的SRS resource都使用该功率控制参数集合计算功率；
2)当SRS resource set包含大于1个功率控制参数集合时，例如N个(N>1)，SRS resource set中SRS resource分为N组，每组SRS resource使用对应的一个功率控制参数集合计算功率。

2)SRS的目标接收功率P0_SRS；
3)SRS的路损补偿因子Alpha_SRS；
4)路损PL测量参数；
5)SRS闭环功率控制进程。
其中用于路损PL测量估计的参考信号RS资源指示可以与下述的PUSCH的路损测量参数共享同一个资源池。即基站配置一个PL测量估计 参数的资源池，SRS resource set只指示资源池内的编号。
路损测量参数包括以下至少之一：用于路损测量的参考信号RS资源类型指示、用于路损测量的参考信号RS资源指示、多个路损测量的参考信号的路径损耗值的处理规则。
所述SRS闭环功率控制进程是指SRS专用的闭环功率控制进程，每个cell可以配置一个或者多个，每个cell中被配置为同样进程的SRS resource set可以进行闭环功率调整量的共享。

基站还为以上PUSCH的功率控制参数配置与授权类型的关联关系。例如，J1、K1、L1分别与授权类型关联。例如J1＝3，包含J1_1，J1_2和J1_3，其中J1_1和J1_2分别与grant based类型关联，而J1_3与grant free类型关联。K1＝3，包含K1_1，K1_2和K1_3，其中K1_1和K1_2分别与分别与grant based类型关联，而K1_3与grant free类型关联。L1＝2，包含L1_1，L1_2，其中L1_1与grant based类型关联，而L1_2与grant free类型关联。
基站以以下方式之一为UE指示SRS的波束资源信息：
1)在无线资源控制(Radio Resource Control，RRC信令)中配置SRS resource set或SRS resource与波束资源指示信息的关联关系。所述关联关系可以是：在SRS resource set或SRS resource中配置波束资源指示信息，例如，SRS资源指示(SRI)、跟踪参考信号资源指示(TRI)、同步信号块(SS block)指示、CRI，或用以上波束资源信息的QCL关系指示的波束资源信息，或传输预编码矩阵指示(Transmitted Precoding Matrix Indicator，TPMI)；

3)在物理层信息，如下行控制信息(Downlink Control Information，DCI)，中指示SRS resource set或SRS resource与波束资源指示信息的关联关系。所述关联关系可以是：为触发的SRS resource set指示波束资源指示信息。
UE接收SRS resource set的配置信息、PUSCH的功率控制参数配置信息，并接收相关的MAC CE、物理层信息，获知SRS resource set或SRS resource与波束资源指示信息的关联关系。
满足以下的一个或者多个条件的(和/或)组合时，使用PUSCH的功率控制参数代替SRS resource set中的部分或者全部功率控制参数。
1)当应用场景为非波束的场景
2)SRS resource set配置为非周期的；
3)SRS resource set配置为半静态的；
4)SRS resource set中的SRS resource个数等于1；
5)SRS resource set中的SRS resource重复次数等于1；
6)与SRS resource set或SRS resource关联的天线资源与PUSCH关联的天线资源匹配；
所述天线资源是指与物理或者虚拟天线的资源，如天线端口、天线面板、天线端口分组等。
7)与SRS resource set或SRS resource关联的波束资源指示信息与PUSCH功率控制参数相关联的部分或者全部波束资源指示信息相同或匹配；
其中，匹配是指波束资源以相同的资源编号指示，或者波束资源之间满足特定的QCL关系。
当与SRS resource set或SRS resource关联的波束资源个数大于1时，匹配是指所有的与SRS resource set或SRS resource关联的波束资源和与PUSCH功率控制参数相关联的波束资源之间都满足特定的QCL关系。
所述的PUSCH功率控制参数相关联的波束资源指示信息，可以是PUSCH的DMRS的发送资源，例如天线端口，发送波束，SRI等。8)与SRS resource set或SRS resource授权类型与PUSCH功率控制参 数相关联的授权类型相同。
其中，所述的授权类型是指grant based或者grant free。
9)SRS resource set中SRS resource发送的波束资源信息是由基站指示的，或者SRS resource set中SRS resource发送的波束资源信息是非基站透明的。
其中，所述的SRS resource set中SRS resource发送的波束资源信息是由基站指示的，是指基站通过RRC信令配置，或者通过MAC CE或者物理层信令，如DCI，配置或者指示所述的SRS resource的发送波束资源。
所述发送波束资源可以是以下至少之一：SS block的资源指示、SRS的资源指示(SRI)、TRS的资源指示(TRI)、CSI-RS的资源指示(CRI)。
所述发送波束资源是参考在基站指示给所述SRS resource之前的一次或者多次传输。例如，发送波束资源参考SS block的传输，过程如下：
基站周期发送M个SS block，并且依次编号为m＝0～M-1。假设UE需要训练N个波束。则UE首先使用同一个接收波束，测量一个周期内的M个SS block，得到各自的RSRP，在后面的SS block的周期用不同的接收波束测量得到其他的基站到UE的不同波束对的RSRP，同时计算这些波束对的PL。对比之后，UE将其中PL比较小的波束对反馈给基站，基站可以依据这些信息对后续调度指示波束资源。
假设基站指示SS block中的m＝1给某次SRS作为发送波束的参考信息，在此之前UE至少接收了N次m＝1的波束的SS block，那么UE选择接收性能最好的(例如RSRP最大，或者PL最小)一次SS block发送所对应的接收波束作为SRS的发送波束。
另外，发送波束资源参考SRS的资源指示的传输，过程如下：
基站为UE配置SRS resource set，假设用SRS resource set ID 1标识，其中配置了多个SRS resource，假设分别用SRS resource ID 1～x标识，基站不为UE指定发送波束资源，即SRS的发送波束对基站透明的方式，此时 UE需要自己确定发送的波束资源。一般针对UE需要进行大范围的波束扫描，共享PUSCH的功率控制参数的必要性不强。该过程可能是用于上行波束管理，或者上行波束扫描的。UE发送了SRS之后，基站侧进行测量，并依据这些测量结果对后续的传输指示波束资源。
在上述SRS resource set之后，基站采用发送波束对基站非透明的方式，指示某个SRS的发送波束是SRS resource set ID 1中的SRS resource ID 1。
SRI作为SRS资源的指示信息，可以指以下之一：SRS resource set指示信息与SRS resource set内部的SRS resource的指示信息；仅有SRS resource的标识信息，对于该UE的所有SRS resource set的所有SRS resource的有统一标识的情况。
上述条件判断是否开启也可能是基于基站配置的：基站为每个SRS resource set配置是否允许SRS共享PUSCH的功率控制过程的参数。
当不允许SRS共享PUSCH的功率控制过程时，使用SRS resource set中配置的功率控制参数计算发送功率。
当允许SRS共享PUSCH的功率控制过程时，UE根据以下的一个或者多个条件的组合结果判断是否共享PUSCH的功率控制过程。
满足上述条件时，确定功率控制参数的方法为以下之一：
1)用与SRS resource set或SRS resource关联的波束资源指示信息相关联的PUSCH的全部功率控制参数为SRS resource set计算发送功率；
2)用与SRS resource set或SRS resource关联的波束资源指示信息相关联的PUSCH的部分功率控制参数为SRS resource set计算发送功率；
3)用与SRS resource set或SRS resource关联的授权类型相关联的PUSCH全部功率控制参数为SRS resource set计算发送功率；
4)用与SRS resource set或SRS resource关联的授权类型相关联的 PUSCH部分功率控制参数为SRS resource set计算发送功率。
即用所述PUSCH部分或全部功率控制参数分别指包括以下部分或者全部PUSCH的功率控制参数代替相应的SRS的配置参数：
1)替代关系1：用P0_PUSCH与P0_SRS_OFFSET之和代替P0_SRS；
2)替代关系2：用Alpha_PUSCH代替Alpha_SRS；
3)替代关系3：用为PUSCH配置的PL估计的RS资源指示代替为SRS配置的PL估计的RS资源指示；
4)替代关系4：用为PUSCH配置的闭环功率调整量代替为SRS配置的闭环功率调整量。
在一些实施例中，部分或者全部的PUSCH功率控制参数是基站配置，或者预定义的。
预定义是指支持上述的一种或者多种替代关系。
基站配置是指，基站为UE配置以上的一种或者多种替代关系。例如，支持bitmap的方式，用4bit信息分别指示替代关系1～4是否启用。或者，预定义若干个替代关系子集，如4个子集，子集1是配置替代关系1～4都启用，子集2是上述替代关系中只有替代关系3和4启用，子集3是上述替代关系中只有替代关系4启用，子集4是上述替代关系都没有启用，即不支持用PUSCH的参数替代SRS的参数。
上述过程支持不同SRS类型的举例：
基站为SRS for DL CSI acquisition、SRS for antenna switching的SRS resource set配置不允许SRS共享PUSCH的功率控制过程的参数，而为SRS for UL CSI acquisition、SRS for beam management的SRS resource set配置允许SRS共享PUSCH的功率控制过程的参数。在使用波束的场景，UE可以通过波束关系判断SRS for UL CSI acquisition、SRS for beam management是否共享PUSCH的功率控制过程；在非波束场景，不存在SRS for beam management，SRS for UL CSI acquisition可以共享PUSCH的功率控制参数。
本实施例提供对于路径损耗(PL)测量的多个下行(DL)参考信号(RS)的增强的方案：
基站为UE配置K个路损测量参数，每个路损测量参数中包含以下至少之一：下行参考信号DL RS资源的指示信息，对多个PL值的处理规则。
下行参考信号DL RS资源的指示信息包括以下之一：DL RS的类型、DLRS的资源指示。
基站在DL RS资源中配置一个波束资源的指示，UE只使用该波束资源的DL RS测量PL。
基站在DL RS资源中配置一个波束资源的指示，UE通过基站配置的QCL关系获得与该波束资源有QCL关系的一组DL RS，用于测量PL。
基站在DL RS资源中配置一个波束资源的指示，并指示UE通过基站配置的QCL关系获得与该波束资源有QCL关系的一组DL RS，用于测量PL。
基站没有为PL计算配置DL RS资源，或者在DL RS资源中配置一个保留值，此时UE自行决定所用于测量计算PL使用的DL RS，或者假定上下行互易性存在用下行信道关联的DL RS计算PL
基站在DL RS资源中配置多于1个波束资源的指示，这些波束资源指示是同类型的波束资源指示，在特定场景下，这些同类型的波束资源指示满足特定的QCL关系。
基站在DL RS资源中配置多于1个波束资源的指示，这些波束资源指示包含不同类型的波束资源指示，在特定场景下，这些不同类型的波束资源指示满足特定的QCL关系。
所述的波束资源的指示是指以下至少之一用于指示基站的下行发送波束的信息：CRI(s)、SS-block资源指示、TRS资源指示。其中，CRI是指CSI-RS资源指示(CSI-RS resource indication)，用该信息指示UE用指定的 CSI-RS进行PL测量。SS-block资源指示是指NR-SS同步信号中的SSS(secondary synchronization signal)或者PBCH(primary broadcast channel，主广播信道)的DMRS(demodulation reference signal，解调参考信号)的资源指示，用该信息指示UE用指定的SS-block进行PL测量。TRS是跟踪参考信号(Tracking Reference Signal)，TRS资源指示是指示UE用指定的TRS进行PL测量。
所述特定场景包括：对波束场景的PUSCH配置功率控制参数时、对波束场景的PUCCH配置功率控制参数时、对波束场景的用于获取下行或者上行CSI的SRS配置功率控制参数时。
所述对多个PL值的处理规则是对配置的多个DL RS资源发送的DL RS测量的多个PL进行处理得到一个PL值的规则。包括：
对满足预定条件的多个PL进行排序，按照预定的权值进行加权平均。所述预定条件包括，PL小于配置的门限。基站配置所述的预定权值。
本实施例提供SRS resource set保持功率一致，多个周期保持功率一致的方案：
SRS资源集合包含至少一个SRS资源，同一个SRS资源集合中的多个SRS资源发送功率一致。
对于周期的SRS资源集合，基站配置周期，UE周期性地使用SRS资源集合中的SRS资源发送SRS。
在一个周期内占用同一个SRS资源集合中的SRS资源发送的SRS，发送功率保持一致。
对于周期的SRS资源集合，基站配置维持相同发送功率的周期数，在所述的周期数内占用所述的SRS资源集合的SRS资源发送的SRS，发送功率保持一致。
对于非周期的SRS资源集合，由物理层信令进行SRS触发，占用同一 次触发中的SRS资源集合中所指示的多个SRS资源的SRS保持发送功率一致。
所述SRS触发可能指示一次SRS资源集合的SRS资源，或者指示重复多次SRS资源集合的SRS资源。占用同一次触发中的SRS资源集合中所指示的多个SRS资源的SRS保持发送功率一致。
对于半静态调度的SRS资源集合，在激活状态，与周期的SRS资源集合类似，基站配置周期，UE周期性地使用SRS资源集合中的SRS资源发送SRS。
在一个周期内占用同一个SRS资源集合中的SRS资源发送的SRS，发送功率保持一致。
对于半静态的SRS资源集合，基站配置维持相同发送功率的周期数，在所述的周期数内占用所述的SRS资源集合的SRS资源发送的SRS，发送功率保持一致。
本实施例提供了SRS重复发送次数对SRS发送功率的影响：
SRS时域重复发送可以增强接收质量，提高覆盖。
SRS时域重复发送还可能实现另一种目的：减小发送功率，从而减轻对其他通信节点的干扰。
基站通过以下方式至少之一体现SRS重复发送次数对SRS发送功率的影响：
1)用SRS时域重复因子调节发送功率参量；
例如，重复发送的总次数作为一个功率计算的系数。下式是一种实现方式，R SRS,c(i)是重复传输的总次数，如果传输一次，重传一次，一共两次，则该值为2。其他参量见实施例2的描述。
Figure PCTCN2018116277-appb-000004
2)基站配置SRS时域重复因子对发送功率的影响系数；
例如，基站在预配置的一个影响系数表中挑选一个配置给UE，假设该影响系数表包括0和1以及0到1之间的数值，如R SRS,c∈{0,0.5,1}。0等效于该功能没有启用；1等效于完全开启该功能，如重复发送2次，则SRS的发送功率相比没有启用该功能下降3dB；而0到1之间的数值，则表示该影响系数处于部分开启状态。
下式是一种实现方式，β SRS,c是所述的影响系数。其他参量见上。
Figure PCTCN2018116277-appb-000005
3)用开关控制是否启用SRS时域重复因子影响发送功率的功能。
如果启用，则对SRS计算的发送功率按SRS时域重复因子的比例进行调整。例如，时域重复发送2次，则SRS的发送功率相比没有启用该功能下调3dB。
例如，用开关配置上式中的β SRS,c取值为0或者1。
此处提供PUCCH的功率控制参数与PUSCH/PDSCH的关系的实施例：
PUCCH与PUSCH的波束资源可能不相同，PUCCH的调度时间一般较长，资源配置信息，例如发送波束资源信息，可能是RRC信令进行更新，而PUSCH可能有更灵活的调度机制，资源配置信息，例如发送波束资源信息，可能是RRC信令、MAC CE、或者物理层信令指示。在一些场景，PUCCH临时采用PUSCH的发送波束资源信息和/或功率控制机制会带来好处。
基站为UE配置PUCCH的功率控制参数，并为PUCCH配置和/或调度资源，UE根据发送的PUCCH的资源可以确定功率控制参数，包括开环功率控制参数、路损计算参数、闭环功率控制参数，计算PUCCH的发送功率。
基站为UE配置PUSCH的功率控制参数，并为PSCCH配置和/或调度 资源，UE根据发送的PUSCH的资源可以确定功率控制参数，包括开环功率控制参数、路损计算参数、闭环功率控制参数，计算PUSCH的发送功率。
当以下条件至少之一满足时，PUCCH可以临时使用PUSCH的功率控制参数和/或PUSCH的发送波束资源。
1)PUSCH和PUCCH在同一个slot中；
2)PUSCH和PUCCH是频分的；
3)PUCCH与PUSCH的发送波束相同；
4)PUCCH与PUSCH的发送波束满足特定的QCL关系。
上述PUCCH临时使用PUSCH的功率控制调整参数和发送波束资源只对本次PUCCH传输有效。该次PUCCH发送不影响其他的PUCCH的发送波束资源和功率控制参数。
当PUCCH临时使用PUSCH的功率控制参数时，其闭环功率控制参数使用PUSCH的闭环功率控制参数，即PUSCH的闭环功率调整量，该量由PUSCH的闭环功率进程更新，PUCCH临时使用该量，不对该量进行更新。
当PUCCH临时使用PUSCH的功率控制参数时，其开环功率控制参数中的目标接收功率P0值由PUSCH的目标接收功率P0值与PUCCH的目标接收功率偏移值的和值确定。PUCCH的目标接收功率偏移值是基站配置的PUCCH相对于PUSCH的目标接收功率的偏移值。
如下式是一种实现方式：
Figure PCTCN2018116277-appb-000006
其中，i是时间单位编号，例如，子帧号、时隙号、OFDM符号的编号等；j是PUSCH开环功率控制参数集合的编号，F是PUCCH的格式编号；l是PUSCH闭环功率控制参数集合的编号，也指PUSCH的闭环功率控制的进程标识，或者闭环功率控制loop的标识。P O_PUSCH,c(j)、α c(j)、PL c、f c(i,l)分别是PUSCH的目标接收功率、路损补偿因子、路损计算参数、闭环功率 控制调整量。
基站为UE配置PUSCH的功控参数，包括至少一套开环功控参数(至少包括目标接收功率P0，路损因子alpha)、至少一套路损测量参数(PL计算的RS资源配置)、至少一套闭环功控进程，分别用开环功控参数标识、路损测量参数标识、闭环功控进程标识指示。
基站还为UE配置以下至少之一的关联：
1)开环功控参数与参考信号索引的关联；
2)路损测量参数与参考信号索引的关联；
3)闭环功控进程与参考信号索引的关联；
4)开环功控参数与路损测量参数的关联；
5)开环功控参数与闭环功控进程的关联；
6)路损测量参数与闭环功控进程的关联；
7)开环功控参数路/损测量参数与闭环功控进程的关联
基站通过配置以下至少之一可以指示UE获得PUSCH功控参数：参考信号索引、开环功控参数标识、路损测量参数标识、闭环功控进程标识。
闭环功控进程标识确定闭环功控进程，也叫闭环功控loop(环)，UE为每个闭环功控进程(假定闭环功控进程标识是l)维护本地功率调整量f(i,l)。
当开环功率控制参数中的目标接收功率P0和/或路损因子alpha被配置或者重新配置时，闭环功率调整参数f(i,l)被重置。包括以下情况之一：
1)PUSCH的开环功率控制参数集合都被配置或重新配置时，则所有闭环功控进程标识对应的f(i,l)都被重置。
2)PUSCH的开环功率控制参数集合的一部分被配置或重新配置时，则只有被配置或者重新配置的开环功控参数集合索引所关联的闭环功控进程标识对应的f(i,l)都被重置。
3)PUSCH的开环功率控制参数集合中的部分参数，如P0和/或alpha，被配置或重新配置时，则只有被配置或者重新配置的开环功控参数集合索引所关联的闭环功控进程标识对应的f(i,l)都被重置。
以上内容也适用于PUCCH和SRS的功控参数。
基站可以配置重置或者继承闭环功控进程。配置信令可以是RRC信令、MAC CE、或者是PHY信令。
基站可以配置在不同信道、信号之间继承闭环功控进程。配置信令可以是RRC信令、MAC CE、或者是PHY信令。
本申请能够为SRS-CSI for PUSCH、SRS-CSI for PDSCH、SRS-BM U1/U2/U3的不同需求确定统一的功率控制公式和配置架构。
1)显式或者隐式地(例如，通过SRS resource的特性，尤其是与波束beam的绑定关系)指示SRS与PUSCH是否共享功率控制参数P0/alpha/PL，是否共享f(i)，f(i)表示子帧i的功率控制修正函数；
2)独立的SRS功率控制参数配置，需要为SRS的多个J、K、L建立关联，方便SRS的动态指示。通过配置波束(组)(beam(group))与j、k、l的关联关系，或者配置j、k、l的关联关系；
3)共用PUSCH的功率控制参数时，隐式和显式的确定SRS使用PUSCH的功率控制参数的方法。

此处有个细节需要进一步阐述一下如图6所示，天线1对应n个elment(即由天线1发送的信号需要通过[w11,w21,...,wn1]加权之后在天线1关联的n个element发送出去，从而形成射频波束),天线2对应n个element,天线1中element上的加权因子为w1＝[w11,w21,...wn1],w2＝[w12,w22,...,wn2],当w1＝w2时，SRS resource 1由天线1发送，SRS resource 2由天线2发送，在本实施例的一种实施方式中，可以称SRS resource1和SRS resource 2的空间滤波参数相同，或者称SRS resource 1和SRS resource 2对应相同的发送波束不同的天线，本实施例的另一种实施方式中，也可以称SRS resource1和SRS resource 2的空间滤波参数不同，或者称SRS resource 1和SRS resource 2对应不同的发送波束不同的发送天线。
“波束不变相同天线”表示这个SRS resource set中的不同SRS resource是同一波束同一天线的重复发送，
“天线切换波束相同”表示不同的SRS resource对应不同的天线或者天线组，且对应相同的射频加权因子(或者空间滤波因子)，如图6所示，SRS resource1和SRS resource2对应的不同的天线，但是射频加权因子w1＝w2.“天线切换波束不同’SRS resource1和SRS resource2对应的不同的天线，但是射频加权因子w1和w2不同。
在上述描述中，所述配置参数X是在SRS resource set中配置的，本实施例也不排除上述配置参数X在SRS resource中配置。
本实施例中，所述发送波束也可以称为空间滤波参数。

在一些实施例中，当SRS resource set中每个SRS resource包括的端口数属于预定集合(比如所述预定集合为{1}，或者预定集合为{1,2})则Y的可配置范围为范围3，否则Y的可配置范围为范围4，可选地范围4是范围3的子集。比如范围3为{0～5},范围4为{2～5}.上述可配置范围为数值，本实施例也不排除可配置范围为状态位构成的集合。

简化特征：
在同一载波内，逐个符号对传输的信道和/或信号进行功率调整以满足：
该载波的最大功率限制；
同一个slot内的多个符号间同样类型的信道或者信号保持相同的非零功率，或者非零功率谱密度。
在多个载波内，逐个符号对传输的信道和/或信号进行功率调整以满足：
多个载波的最大功率限制；
同一载波内同一个slot内的多个符号间同样类型的信道或者信号保持相同的非零功率，或者非零功率谱密度。
多个载波同时进行上行发送时，确定发送功率的过程有以下至少之一的特征：
1.计算每个载波上所有的传输的功率，记为Pc,x,ch，其中c为CC的编号，x为slot内OFDM符号的编号，ch为信道或信号，可以是PUSCH、L-PUCCH、短PUCCH(S-PUCCH)、SRS等。
2.在每个载波上逐个符号判断该载波内该符号上的所有传输所需要的功率之和是否超过该载波容许的最大功率限制；
3.在所述载波内，对超过容许的最大功率限制的符号，按预定义的规则处理该载波内该符号上所有传输的发送功率，记为P’c,x,ch。
所述预定义的规则包括：按信道、信号优先级保证高优先级的传输优先获得功率，例如PUCCH的优先级比PUSCH高，PUSCH的优先级比SRS高，PUSCH中包含上行控制信息UCI的比不包含UCI的PUSCH优先级高，PUSCH中按传输的业务优先级进行对比，如包含URLLC业务的PUSCH比包含eMBB的PUSCH优先级高等。剩余的功率在其余优先级较低的传输 中分配，如果有多个同等优先级的传输，多个传输同比例降低功率，或者对某些传输不分配功率，即相应的P’c,x,ch为零。
在所述载波内，在一个slot内，多个符号间同样类型的传输保持相同的功率。如果某些符号上的功率为零，则可以不与其他符号功率一致。方法包括以下之一：取所有符号同样类型的传输功率P’c,x,ch的最小值；取所有符号同样类型的传输P’c,x,ch的非零最小值。
当所有载波的slot长度相同，在所有载波上逐个符号判断该符号上的所有载波的所有传输的功率之和是否超过该UE容许的最大功率限制；
所述功率之和为P’c,x,ch中x取值固定为当前判断的符号的编号，对P’c,x,ch中c和ch项进行遍历求和。
对超过容许的最大功率限制的符号，按预定义的规则处理该符号上所有传输的发送功率，记为P”c,x,ch。
所述预定义的规则包括：按信道、信号优先级保证高优先级的传输优先获得功率，剩余的功率在其余优先级较低的传输中分配。如果有多个同等优先级的传输，多个传输同比例降低功率，或者对某些传输不分配功率，即相应的P”c,x,ch为零。
在一个slot内，每个载波内，多个符号间同样类型的传输保持相同的功率。如果某些符号上的功率为零，则可以不与其他符号功率一致。方法包括以下之一：取所有符号同样类型的传输功率P”c,x,ch的最小值；取所有符号同样类型的传输P”c,x,ch的非零最小值。
当多个载波的slot长度不同，则按照slot长度对多个载波进行分组，对每组分别设置需要保证的功率(guaranteed power)，每组载波独立做以上特征1到7的多载波发送功率的处理。载波组之间的功率是否可以共享以及共享的方法由基站配置或者根据预定义规则确定。
所述基站配置的方法或者预定义规则包括：
配置一，多个载波组之间不能共享功率分配，即多个组的guaranteed  power部分不能被其他组占用，在多个组的guaranteed power之外的剩余功率，可以被先发的传输占用，或者被先确定发送时刻的传输占用。
配置二，如果可以预知某些组在当前传输的时间范围内没有传输，则没有传输的载波组的保证的功率可以被其他组共享，例如短slot载波组在计算功率时，如果长slot没有传输，即至少可以占用长slot载波组剩余时间上设置的guaranteed power。如果不可以预知是否在当前传输的时间范围内是否有传输，则必须要预留guaranteed power。
对于双连接的两个CG(Master Cell Group和Secondary Cell Group)，为每个CG分别设置guaranteed power，CG之间的多个载波之间功率如何共享由基站配置或者根据预定义规则确定。
所述基站配置的方法或者预定义规则包括：
配置一，两个CG之间可以共享功率分配，按照信道和传输的优先级确定功率的分配优先级。
配置一，两个CG之间不能共享功率分配，即CG的guaranteed power部分不能被其他组占用。
配置二，如果可以预知另外的CG在当前传输的时间范围内没有传输，则没有传输的CG的保证的功率可以被其他组共享。如果不可以预知是否在当前传输的时间范围内是否有传输，则必须要为另外的CG预留guaranteed power。
所述符号是指OFDM符号。
所述载波(carrier)，也可以是以下之一：成员载波(component carrier)，小区(cell)，其中小区包括各类型的小区，如服务小区(serving cell)，主小区(primary cell)、辅小区(secondary cell)，以及主辅小区(primary secondary cell)、PUCCH-SCell等。
所述载波(carrier)，还可以被BWP(BandWidth Partial，部分带宽)、BWP组代替。
优选实施例z+1(载波聚合CA情况下的功率控制)
由于NR支持不同类型的信道、信号之间的时分、频分，如L-PUCCH(long PUCCH)，S-PUCCH(short PUCCH)，PUSCH，SRS，可能有以下组合方式或者其子集：
(L-PUCCH与PUSCH频分复用)与SRS时分复用，再与S-PUCCH时分复用，如图7所示。
由于每个信道、信道的起止符号位置可能不同，所以，在一个slot中，符号上承载的传输的信息、信号类型可能不同。因此，功率控制和PHR(power headroom report)都需要逐个符号进行计算。
一个slot中，逐个符号计算。
另外，同样类型的信道承载的内容还可能有不同优先级，如同样类型PUCCH承载ACK与承载CQI的优先级可能不同，PUSCH承载eMBB与URLLC的优先级不同，一般的，应该保证优先级高的信道和业务的发送功率。
因此，即使对于NR CA中比较简单的场景，numerology(物理帧结构相关参数)相同、同步的NR CA，由于每个CC包含上述信道组合和各自的起止位置可能不同，功率共享也比LTE复杂。
NR的CA功率控制应该逐个符号计算和对比，根据优先级为依据确定功率在多个CC上的分配。在总功率不足的情况下，需要保证高优先级的信道(PUCCH)、业务(URLLC)的发送功率。在同一个CC上，应该保证一个slot内不同符号间的相同的信道功率一致。
NR的CA的功率共享机制描述如下：
1.计算UE的各个CC每个符号上各个信道所需功率Pc,x,ch，并计算每个CC上各个符号是否超过Pcmax,c，即检查是否有符号存在功率不足的情况。其中c为CC的编号，x为slot内OFDM符号的编号，ch为信道或信号，可以是PUSCH、L-PUCCH、S-PUCCH、SRS等。
例如，对于3个CC的载波聚合，假设一个slot内的符号各信道分配的时频资源如图8所示。
下表表1为所述3个CC的一个slot内不同的符号上的信道、信号需要的功率。
Figure PCTCN2018116277-appb-000007
表1
2.对每个CC，如果存在功率不足的符号，按优先级调整对应的CC内各个信道所需的功率P’c,x,ch，使得各个CC上的各个符号不超过各自的Pcmax,c。
假设CC0的PUSCH与L-PUCCH的功率和值超过了P cmax,CC1，则对PUSCH进行调整，调整后的值用P’标识，如表2所示。
Figure PCTCN2018116277-appb-000008
Figure PCTCN2018116277-appb-000009
表2
3.计算每个符号上所有CC的信道的发送功率之和，对比是否超过Pcmax，即检查所有CC之和是否有符号存在功率不足的情况。如果有符号上存在功率不足，对这些符号上存在的优先级高的信道、信号的符号先做功率调整，即保证高优先级的信道或者业务按需要设置发送功率，剩余的功率在在其他较低优先级的信道、信号上分配。
假设x＝2和x＝3两个符号的总功率超过了超过了Pcmax,CC1，则优先保证PUCCH的功率，PUSCH的功率进一步减小，用P”标识，如表3所示。
Figure PCTCN2018116277-appb-000010
表3
4.其他较低优先级的信道、信号如果存在多个，则需要保持等比例降低，其中一些CC上的信道分配的功率可能为零。
5.同一个CC上相同的信道、信号在不同的符号上保持功率一致，如表4所示。
Figure PCTCN2018116277-appb-000011
表4
对于NR CA中numerology不同、同步的NR CA：
numerology不同则符号长度不同，slot长度也不同，在计算长slot的功率时，或许可以知道当前短slot的功率需求，之后的短slot的功率需求不可预知，有必要考虑为后续的短slot预留一定功率，使用扩展的PCM2，即按numerology分组，各分组配置保证的功率(guaranteed Power)。
