上行传输的功率与很多因素有关，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。NR中，上行传输包括物理上行共享信道(Physical Uplink Shared Channel，PUSCH)，物理上行控制信道(Physical Uplink Control Channel，PUCCH)，探测参考信号(Sounding Reference Signal，SRS)等信道的传输。在长期演进(Long Term Evolution，LTE)中，PUCCH信道的功率控制包括开环功控部分、闭环功控部分、路损补偿部分，以及PUCCH格式相关的功率偏移、传输速率相关的功率偏移等。但是，由于PUCCH传输的载荷大小、PUCCH传输所占用的时频资源等都对PUCCH的功率有影响，因此，相关技术中的PUCCH的功率控制不能准确反映这些因素的作用。

具体实施方式
为使本公开的目的、技术方案和优点更加清楚明白，下文中将结合附图对本公开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。
在附图的流程图示出的步骤可以在诸如一组计算机可执行指令的计算机系统中执行。并且，虽然在流程图中示出了逻辑顺序，但是在某些情况下，可以以不同于此处的顺序执行所示出或描述的步骤。
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它传输造成的干扰，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。
一般的通信技术中，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，PL)。PL是用节点1的参考信号的发送功率与节点2收到的参考信号的接收功率之差计算。假设节点2到节点1的传输信道的PL与节点1到节点2的传输信道的PL相同，则节点2可以用上述PL计算节点2作为发送节点到节点1的传输的发送功率。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1接收到传输后进行解析，根据接收的质量为节点2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。此外，与传输相关的特定的量，如发送速率、调制与编码策略(Modulation and Coding Scheme，MCS)等级、发送带宽等，也会影响功率。
下面是LTE的PUSCH信道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。
Figure PCTCN2019082938-appb-000001
上式中下标c是指小区cell，支持载波聚合(Carrier Aggregation，CA)功能的每个成员载波(Component Carrier，CC)对应一个小区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。本文中所有的描述没有特别说明频域范围时，都是针对一个CC进行描述。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P PUSCH的开环部分由目标接收功率P O_PUSCH、路损量PL和路损因子α决定，其中目标接收功率分为小区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控调整量，以传输功控命令(Transmit Power Control Command，TPC Command，即DCI中针对PUSCH的δ PUSCH)的方式通知UE。UE维护一个本地的功率调整量f(i)，根据传输功控命令进行更新，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，P CMAX是UE的最大功率限制。
LTE的cell级目标接收功率P0_nominal是区分PUSCH(半静态、动态、消息3MSG3)和PUCCH，分别对应不同的误块率(Block Error Ratio，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，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。
根据传输功控命令更新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控命令更新UE本地的闭环功率调整量f(i)，而累积式则由基站发送的传输功控命令与该UE本地的闭环功率调整量的历史值共同确定UE本地的闭环功率调整量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。对于PUCCH传输，忽略下标的含义，功控公式中的UE本地的闭环功控调整量用g(i)表示，与PUSCH的f(i)含义类似，是用于PUCCH的UE本地的闭环功率调整量。
UE本地的闭环功率调整量f(i)，也称为功控调整状态(power control adjustment state)。
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。为了支持波束的方式，功率控制参数分为3部分配置：开环功控参数、闭环功控参数、路损的RS参数。其中每个部分支持配置多个，即开环功控参数(或其集合)最多可以配置J个，每个开环功控参数(或其集合)的编号为j；路损的RS参数(或其集合)最多可以配置K个，每个路损的RS参数(或其集合)的编号为k；闭环功控参数(或其集合)最多可以配置L个，每个闭环功控参数(或其集合)的编号为 l；其中，j为大于0小于等于J的整数，k为大于0小于等于K的整数，l为大于0小于等于L的整数，并且J、K、L均为大于0的整数。
如果UE支持多个波束(或波束组)，则基站配置每个可能的波束(或波束组)与开环功控参数、闭环功控参数、路损的RS参数之间的关联。波束(或波束组)可以通过参考信号资源指示。
参考信号包括以下至少之一：上行探测信号(Sounding Reference Signal，SRS)，信道状态信息参考信号(Channel State Information Reference Signal，CSI-RS)，辅同步信号块(secondary Synchronization Block，SSB)，相位跟踪参考信号(Phase Tracking Reference Signal，PTRS)，跟踪参考信号(Tracking Reference Signal，TRS)，解调参考信号(Demodulation Reference Signal，DMRS)。
基站为UE的上行传输指示参考信号资源，使UE获得该参考信号资源所关联的功率控制参数。
在一个例子中，基站为UE的PUSCH传输配置J1个开环功控参数(或其集合)，K1个路损的RS参数(或其集合)，L1个闭环功控参数(或其集合)。基站为UE配置PUSCH的传输方式，如基于码本的传输(codebook based transmission)，或基于非码本的传输(non-codebook based transmission)。基站为UE配置基于PUSCH的传输方式的上行探测信号资源集合(SRS resource set)，其中包括至少一个上行探测信号资源(SRS resource)。基站为UE发送下行控制信息(Downlink Control Information，DCI)，其中包括SRS资源指示(SRS Resource Indicator，SRI)，SRI可以用于确定PUSCH传输的预编码。不同PUSCH传输方式的DCI中指示的SRI集合可能不同。例如，基于码本的传输的SRI集合可能有2个SRI，每个SRI代表一个SRS资源(Resource)；基于非码本的传输的SRI集合可能有15个SRI，每个SRI代表一个SRS resource或者多个SRS resources。基站为UE配置DCI中指示的SRI集合中的每一个成员SRI与以下至少之一的关联：开环功控参数(或其集合)编号，路损的RS参数(或其集合)编号，闭环功控参数(或其集合)编号。基站通过DCI中的SRI告知UE PUSCH传输的功控参数。
在另一个例子中，基站为UE的PUCCH传输配置J2个开环功控参数(或其集合)，K2个路损的RS参数(或其集合)，L2个闭环功控参数(或其集合)。基站为UE配置PUCCH的至少一个空间关系，并且配置空间关系与PUCCH传输的功控参数的关联。基站通过以下方式至少之一告知UE PUCCH的空间关系：通过高层信令为PUCCH配置了一个空间关系； 通过高层信令为PUCCH配置了至少1个空间关系，并且通过MAC CE和/或物理层信令指示其中的一个；或者，UE自己决定PUCCH的空间关系。例如，在UE为非RRC连接状态时，UE自己决定PUCCH的空间关系。
UE可以依据下行信道测量结果确定PUCCH的空间关系。
UE根据PUCCH的空间关系、空间关系与PUCCH传输的功控参数的关联获得PUCCH传输的功控参数。
所述空间关系用参考信号信息指示。
SRS resource，SRS resource set、功控参数基于以下至少之一的频域单位进行配置：BWP，CC。
对于PUCCH，功率计算公式如下：
Figure PCTCN2019082938-appb-000002
其中F是指不同的PUCCH的格式。例如，PUCCH格式0，格式1，......，格式4。对于PUCCH格式2/格式3/格式4，可以支持不同大小的载荷。
对于大载荷，例如，大于11比特，Δ TF，f，c(i)＝10log 10(2 K1·BPRE(i)–1)；对于小载荷，例如，小于等于11比特，Δ TF，f，c(i)＝10log 10(K2·BPRE S(i))。其中，TF指传输格式(Transport Format)，f指载波编号，c指小区，i指上行子帧编号，或者时隙编号，或者PUCCH传输编号；BPRE是Bit Per Resource Element，即比特速率，可包括PUCCH载荷比特数与RE个数的比值。PUCCH的载荷包括ACK/NAK(HARQ的肯定/否定的应答)，SR(调度请求)，CSI(信道状态信息)，以及可能的CRC比特数。BPRE S是用于小载荷的BPRE。小载荷的BPRE可能没有CRC。K1和K2为BPRE的系数。
相关标准对每种PUCCH的格式配置了一个功率偏移值Δ F_PUCCH(F)为简化标准，对K1和K2不分多种情况取值，则其他因素(例如，OFDM符号数量，RB个数，是否跳频等)对功率的影响无法在相关技术的功控框架中体现。而仿真结果显示，这些因素无法忽略，否则拟合结果和仿真结果相差过大。
基站为UE配置至少一个成员载波(Component Carrier，CC)，每个CC包括至少一个带宽部分(Bandwidth Part，BWP)。
基站为UE配置PUCCH参数，可包括：在BWP上配置PUCCH资源集合，每个PUCCH资源集合包括至少一个PUCCH资源。

实施例1
基站为UE配置PUCCH的功率控制参数，所述功率控制参数为PUCCH资源配置Δ F_PUCCH(F)，或者Δ F_PUCCH(F)基准量和Δ F_PUCCH(F)的修正量。其中，Δ F_PUCCH(F)表示发送功率偏移量。
发送功率偏移量又可以分为两部分配置：发送功率偏移量的基准量、发送功率偏移量的修正量。
发送功率偏移量的修正量与发送功率基准量之和可以得到发送功率偏移量。
或者，发送功率偏移量的修正量可以是发送功率偏移量。
由于PUCCH资源中配置了PUCCH的格式、RB起始位置、RB个数、OFDM符号起始位置、OFDM符号数量、是否跳频，因此基站可以根据以上参数至少之一对PUCCH资源配置Δ F_PUCCH(F)，或者Δ F_PUCCH(F)基准量和Δ F_PUCCH(F)的修正量。
虽然基站在配置参数时并不能确定实际传输时的载荷，但是基站在PUCCH资源集合上配置最大载荷大小，所以该PUCCH资源集合中的每个PUCCH资源也有对应的载荷范围。因此，基站还可以依据PUCCH资源的载荷范围为PUCCH资源配置Δ F_PUCCH(F)，或者Δ F_PUCCH(F)基准量和Δ F_PUCCH(F)的修正量。
基站也可能为每个PUCCH资源配置N个Δ F_PUCCH(F)，或者N个Δ F_PUCCH(F)的修正量，分别对应不同的载荷区间。N为大于或等于1的整数。UE根据实际的PUCCH传输的载荷大小，选择N个中的一个Δ F_PUCCH(F)，或者Δ F_PUCCH(F)基准量和Δ F_PUCCH(F)的修正量进行PUCCH的功控。
载荷区间可以是预先配置的固定值。例如，[3,11]标识载荷范围是3比特到11比特。
载荷区间还可以是根据数据速率或编码速率确定的。
例如：PUCCH的资源集合上配置的最大载荷大小范围很大，在对应的载荷范围内，可能需要配置大于1个Δ F_PUCCH(F)，分别对应多个载荷范围。例如PUCCH的资源集合上的最大载荷大小是100比特。对于其中一个PUCCH资源配置了3个Δ F_PUCCH(F)，分别对应3个载荷大小区间，如，3个载荷大小区间为比特数数范围在[3,11]，[12,22],[23,正无穷]。当UE发送PUCCH承载的载荷为10比特时，则选择第一个载荷区间对应的Δ F_PUCCH(F)。
又如，基站为UE配置了3个PUCCH的资源集合，每个资源集合独立配置最大载荷大小。第一PUCCH的资源集合的最大载荷大小为2比特，第二PUCCH的资源集合的最大载荷大小为11比特，第三PUCCH的资源集合的最大载荷大小为100比特。则UE将多个PUCCH的资源集合结合起来判断具体的PUCCH使用的PUCCH的资源集合。第一PUCCH的资源集合载荷大小为1、2比特；第二PUCCH的资源集合载荷大小为3到11比特；第三PUCCH的资源集合载荷大小为12到100比特。如果PUCCH的实际载荷是20bit，则应该选择第三PUCCH的资源集合。
基站配置的是Δ F_PUCCH(F)的修正量时，该Δ F_PUCCH(F)的修正量需要结合Δ F_PUCCH(F)的基准量决定PUCCH的功控中Δ F_PUCCH(F)项。因此，基站还要为UE配置Δ F_PUCCH(F)的基准量。
例如：基站在BWP上为每个PUCCH格式配置Δ F_PUCCH(F)的基准量。则该Δ F_PUCCH(F)的基准量用于该BWP上的所有PUCCH资源。实际的Δ F_PUCCH(F)是用Δ F_PUCCH(F)的基准量与对应的PUCCH资源配置的Δ F_PUCCH(F)修正量一起确定的。如，Δ F_PUCCH(F)＝Δ F_PUCCH(F)基准量+Δ F_PUCCH(F)修正量。
实施例2
基站为UE配置PUCCH的功率控制参数，包括：为PUCCH资源集合配置N个Δ F_PUCCH(F)或者Δ F_PUCCH(F)的基准量和Δ F_PUCCH(F)的修正量，所述N个Δ F_PUCCH(F)或者 Δ F_PUCCH(F)的修正量分别对应不同的载荷区间，其中，N为大于或等于1的整数。UE根据实际的PUCCH传输的载荷大小，选择N个中的一个Δ F_PUCCH(F)，或者Δ F_PUCCH(F)的修正量进行PUCCH的功控。
由于PUCCH资源集合上配置了最大载荷大小，因此基于set配置的Δ F_PUCCH(F)可以体现载荷的不同。
例如，N为2时，对应大载荷区间和小载荷区间。载荷区间的界限可以是预定义的，例如大于11比特称为大载荷区间，小于等于11比特称为小载荷区间。载荷区间的界限也可以是根据比特速率或者编码速率与RB个数确定的。
又如，N为3时，对应3种载荷，>22比特的为第一种载荷区间，>11且<＝22比特的为第二种载荷区间，<11比特的为第三种载荷区间。
除了载荷因素外，PUCCH资源占用的OFDM符号数量，RB个数，是否跳频等因素也应该在功控公式中体现。BPRE本身可以体现比特速率，也就是载荷、OFDM符号数、RB数的综合体现，但是根据场景不同还有必要对这些因素进行调整。
Δ TF，f，c(i)，或者Δ F_PUCCH(F)，或者功率公式中的独立项体现以下至少之一：PUCCH资源占用的OFDM符号数量，PUCCH资源占用的RB个数，PUCCH资源是否跳频。其中，Δ TF，f，c(i)和Δ F_PUCCH(F)表示发送功率偏移量。
是否跳频引起的偏差可以是预定义的或者是配置的。
例如，预定义或者基站配置跳频引入的偏差是2dB。则Δ TF，f，c(i)，或者Δ F_PUCCH(F)，或者功率公式中的独立项会体现该差异。如果跳频打开，则发送功率相对于不打开时的发送功率减少2dB。
PUCCH资源占用的OFDM符号数量引起的偏差是PUCCH资源占用的OFDM符号数的函数。
例如，该函数为
Figure PCTCN2019082938-appb-000003
其中，
Figure PCTCN2019082938-appb-000004
为OFDM符号个数。该函数可以作为Δ TF，f，c(i)，或者Δ F_PUCCH(F)，或者功率公式中的独立项中的一部分，以体现PUCCH资源占用的OFDM符号数量对功控的影响。
PUCCH资源占用的RB数量引起的偏差是PUCCH资源占用的RB数量的函数。
例如，该函数为-2log 10(M PUCCH,c(i))。其中M PUCCH,c(i)为RB数量。该函数可以作为Δ TF，f，c(i)，或者Δ F_PUCCH(F)，或者功率公式中的独立项中的一部分，以体现PUCCH资源占用的RB数量对功控的影响。
上述功率公式中的独立项，是指不同于相关功率公式中的已有项，而是新增加一项。
例如，表1是PUCCH格式2、3、4的Δ F_PUCCH(F)中体现OFDM符号数量，RB个数调整量的示例。表2是PUCCH格式2、3、4的Δ TF，f，c(i)中体现OFDM符号数量，RB个数调整量的示例。

基站为UE配置PUCCH的功率控制参数，包括：为BWP配置N个Δ F_PUCCH(F)，所述N个Δ F_PUCCH(F)分别对应不同的载荷区间，其中，N为大于或等于1的整数。UE根据实际的PUCCH传输的载荷大小，选择N个中的一个Δ F_PUCCH(F)进行PUCCH的功控。
例如，N为2时，对应大载荷区间和小载荷区间。例如大于11比特称为大载荷区间，小于等于11比特称为小载荷区间。
例如，基站为UE配置了1个CC，包括3个BWP，其中第一个BWP上有PUCCH配置。BWP上配置了2个Δ F_PUCCH(F)，分别对应大载荷区间和小载荷区间。
除了载荷因素外，PUCCH资源占用的OFDM符号数量，RB个数，是否跳频等因素也应该在功控公式中体现。BPRE本身可以体现比特速率，也就是载荷、OFDM符号数、RB数的综合体现，但是根据场景不同还有必要对这些因素进行调整。
Δ TF，f，c(i)，或者Δ F_PUCCH(F)，或者功率公式中的独立项体现以下至少之一：PUCCH资源占用的OFDM符号数量，PUCCH资源占用的RB个数，PUCCH资源是否跳频。
是否跳频、PUCCH资源占用的OFDM符号数量、PUCCH资源占用的RB数量的细节描述与实施例2相同。
当基站为UE为BWP配置的Δ F_PUCCH(F)数量为1时，Δ F_PUCCH(F)为基本Δ F_PUCCH(F)值，由Δ F_PUCCH(F)修正量和Δ F_PUCCH(F)的基准量共同确定实际的Δ F_PUCCH(F)值。

例如，对于PUCCH格式2，Δ F_PUCCH(F)的基准量配置为4dB。不同载荷区间的差异是预先定义的，如大载荷区间Δ F_PUCCH(F)修正量为3dB，小载荷区间Δ F_PUCCH(F)修正量为1dB。

例如，对于PUCCH格式2，Δ F_PUCCH(F)的基准量配置为4dB。基站为UE的BWP配置N＝2个Δ F_PUCCH(F)的修正量，分别对应2个不同的载荷区间。如大载荷区间Δ F_PUCCH(F)修正量为3dB，小载荷区间Δ F_PUCCH(F)修正量为1dB。

例如，高层信令配置了至少一个PUCCH的空间关系，MAC CE激活其中的一个或者多个空间关系用于当前PUCCH的传输。
又如，高层信令配置了至少一个PUCCH的空间关系，MAC CE激活其中的一个或者多个空间关系作为激活空间关系子集，物理层信令在MAC CE激活的子集中指示一个或者多个空间关系用于当前PUCCH的传输。
当确定了一个PUCCH的空间关系，即可索引一套PUCCH的功控参数。用以下方式至少之一确定PUSCH的功控参数。
1.PUSCH的开环功控参数由PUCCH的开环功控参数确定，包括。PUSCH的开环功控参数由PUCCH的开环功控参数直接确定。
或者，PUSCH的开环功控参数可以使用PUCCH的开环功控参数与PUCCH与PUSCH的偏差共同确定。其中PUCCH与PUSCH的偏差至少包括目标接收功率的偏差。该偏差可以是预定义的或者是基站配置的。如PUSCH的P0比PUCCH的P0低2dB。
2.PUSCH的PL的RS参数由PUCCH的PL的RS参数确定；即PUSCH的PL值与PUCCH的PL的值使用相同的RS。
3.PUSCH的闭环功控参数由PUCCH的闭环功控参数确定。包括以下至少之一：
1).累积式闭环功控是否打开。
2).PUSCH的UE本地的闭环功率调整量由PUCCH的UE本地的闭环功率调整量确定。包括以下之一。
a.PUCCH的UE本地的闭环功率调整量用作PUSCH的UE本地的闭环功率调整量。
b.PUSCH的闭环功控参数在预定时刻使用PUCCH的闭环功控参数，在其余时刻PUSCH使用自己独立维护的UE本地的闭环功率调整量。
例如，当PUSCH第一次使用DCI 0-0时，由于DCI 0-0中没有SRI，因此无法获取功控参数。此时使用当前PUCCH的空间关系获取PUCCH的闭环功控参数，即PUCCH的UE本地的闭环功率调整量。后续使用DCI 0-0调度的PUSCH，因为DCI 0-0中包含了TPC命令，所以PUSCH可以用该TPC命令更新PUSCH的UE本地的闭环功率调整量，即PUSCH独立于PUCCH独立维护UE本地的闭环功率调整量。当PUSCH被用带有SRI的DCI调度之后，PUSCH的功控参数通过SRI索引PUSCH的功控参数。再次出现PUSCH被DCI 0-0调度时，PUSCH使用PUCCH的空间关系获取PUCCH的闭环功控参数，即PUCCH的UE本地的闭环功率调整量作为PUSCH的UE本地的闭环功率调整量的初始值，此后使用DCI0-0调度的PUSCH，使用DCI0-0中包含的TPC命令更新PUSCH的UE本地的闭环功率调整量。
又如，当PUSCH被不带SRI的DCI 0-1调度时，PUSCH使用预定义的SRI索引PUSCH的功控参数；或者PUSCH使用预定义的PUSCH的功控参数，如预定义编号的PUSCH的开环功控参数集合、预定义编号的PUSCH的闭环功控参数集合、预定义编号的PUSCH的PL的RS参数集合。预定义编号是指定义的集合编号中最小的编号，或者指定的编号。
c.当PUCCH的UE本地的闭环功率调整量大于预定门限时，PUSCH的UE本地的闭环功率调整量由PUCCH的UE本地的闭环功率调整量确定。例如，预定门限为0，即PUCCH的UE本地的闭环功率调整量为正值时，PUSCH的UE本地的闭环功率调整量才由PUCCH的UE本地的闭环功率调整量确定。当PUCCH的UE本地的闭环功率调整量小于或等于预定门限时，PUSCH的UE本地的闭环功率调整量为0。
上述的b)与c)可以结合，PUSCH的闭环功控参数在预定时刻当PUCCH的UE本地的闭环功率调整量大于预定门限时使用PUCCH的闭环功控参数，在其余时刻PUSCH使用自己独立维护的UE本地的闭环功率调整量。
所述预定时刻是指以下之一：当PUSCH第一次被DCI格式0-0调度时；从非DCI格式0-0调度PUSCH变换为DCI格式0-0调度PUSCH时；当前PUCCH的空间关系发生变化时。
以上各参数的确定方法可以全部被PUSCH使用，也可以部分地被PUSCH使用。
部分地被PUSCH使用时，功控参数中其余参数使用PUSCH自己的。即，预定义或者基站配置的方式告知UE没有SRI时使用的功控参数。
例如，以上参数中，只有PUCCH的PL的RS被PUSCH的PL的RS直接使用，而PUSCH的开环功控部分的P0使用MSG1的P0值，alpha预定义为1，PUSCH的闭环功控部分的UE本地的闭环功控调整量的初始值预定义为0。
又如，以上参数中，PUCCH的PL的RS被PUSCH的PL的RS直接使用；PUSCH开环功控部分的P0使用PUCCH的开环功控参数的P0值与预定义的偏差值之和，PUSCH的开环部分的alpha使用PUCCH的开环功控参数的alpha值；PUSCH闭环功控部分的UE本地的闭环功控调整量的初始值预定义为0。
又如，以上参数中，PUCCH的PL的RS被PUSCH的PL的RS直接使用；PUSCH开环功控部分使用PUCCH的开环功控参数；PUSCH的闭环功控参数在预定时刻使用PUCCH的闭环功控参数，在其余时刻PUSCH使用自己独立维护的UE本地的闭环功率调整量。
以上当前PUCCH传输也可以是最近的PUCCH传输。
当前PUCCH传输不一定是指真实的某一个PUCCH传输，而是指针对某一段时间的PUCCH的配置参数。例如，MAC CE激活的PUCCH的空间关系，不是针对特定PUCCH，而是从MAC CE激活PUCCH的空间关系的时刻到下次MAC CE去激活或者重激活同类信息的时间段。在该时间段内MAC CE激活的PUCCH的空间关系索引的PUCCH的功控参数都是指当前PUCCH的传输的PUCCH的空间关系索引的当前PUCCH的功控参数。
PUSCH传输的功控参数还可以用PUCCH的特定空间关系对应的PUCCH的功控参数确定。所述PUCCH的特定空间关系包括：预定义的或者基站配置的PUCCH的空间关系。例如，基站配置的至少一个的PUCCH的空间关系中编号最小的或者预定义编号的PUCCH的空间关系。
基站为UE配置至少一套PUSCH的功控参数。基站为UE配置PUCCH的至少一个空间关系。基站为UE配置PUCCH的空间关系与PUSCH功控参数的关联。UE通过PUCCH的空间关系确定PUSCH的空间关系，根据PUSCH的空间关系与PUSCH的功控参数的关联获得PUSCH的功控参数。
基站为UE配置至少一套PUSCH的功控参数。基站为UE配置下行参考信号信息与PUSCH功控参数的关联。UE通过PUSCH相关的下行参考信号信息，根据下行参考信号信息与PUSCH的功控参数的关联获得PUSCH的功控参数。所述PUSCH相关的下行参考信号信息是指以下之一：包含当前PUSCH的调度信息的PDCCH的TCI所指示的下行参考信号信息、UE根据下行信道测量获得的最好下行参考信号。
当PUCCH的空间关系发生变化，例如，MAC CE激活了新的PUCCH的空间关系，则PUCCH的UE本地的闭环功率调整量被重置。
当PUCCH的空间关系发生变化，例如，MAC CE激活了新的PUCCH的空间关系，则PUCCH 的与新的PUCCH的空间关系关联的UE本地的闭环功率调整量被重置。例如，PUCCH的UE本地的闭环功率调整量可能有多个，用编号l表示。基站配置PUCCH的空间关系与PUCCH的闭环功控参数的关联，因此新的PUCCH空间关系对应特定的PUCCH的闭环功控参数。假设MAC CE激活的老的PUCCH的空间关系1与PUCCH的闭环功控参数的编号l＝0关联，MAC CE激活的新的PUCCH的空间关系2与PUCCH的闭环功控参数的编号l＝1关联。则MAC CE激活了新的PUCCH的空间关系，则PUCCH的闭环功控参数的编号l＝1的PUCCH的UE本地的闭环功率调整量被重置。重置是指设置为一个指定值，例如，0。
当PUCCH的空间关系发生变化，例如，MAC CE激活了新的PUCCH的空间关系，并且PUSCH被不带SRI的DCI调度，例如，DCI 0-0，则使用新的PUCCH的空间关系索引的一套PUCCH的功控参数确定PUSCH的功控参数。具体方式同上述。
当PUSCH被不带SRI的DCI调度，例如，DCI 0-0，并且当前PUCCH的空间关系相比上次PUSCH被相同DCI调度时没有发生变化，则PUSCH维持独立于PUCCH的闭环功控。
PUSCH使用调度当前PUSCH传输的DCI中的TPC命令更新PUSCH的本地闭环功率调整量。
或者，当为累积式闭环功率调整时，PUSCH使用调度当前PUSCH传输的DCI中的TPC命令与PUCCH的UE本地的闭环功率调整量之和更新为PUSCH的UE本地的闭环功率调整量。
对于载波聚合CA的场景，配置了PUCCH的小区/BWP上，可以使用上述方法用同一cell/BWP上的PUCCH的空间关系和功控参数确定PUSCH的功控参数。
在没有配置PUCCH的小区/BWP上，由没有SRI的DCI调度的PUSCH的功控参数由该PUSCH所在的PUCCH组内的PUCCH的空间关系和功控参数确定。即用于确定PUSCH的功控参数的PUCCH与PUSCH可以不局限于一个BWP或者服务小区内，属于同一PUCCH组即可。
