首先对本申请的应用场景进行说明：
图1示出了本申请一个示例性实施例提供的通信系统的框图，该通信系统可以包括：终端10和网络设备20。
终端10的数量通常为多个，每一个网络设备20所管理的小区内可以分布一个或多个终端10。终端10可以包括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)等等。为方便描述，本申请实施例中，上面提到的设备统称为终端。
网络设备20是一种部署在接入网中用以为终端10提供无线通信功能的装置。为方便描述，本申请实施例中，上述为终端10提供无线通信功能的装置统称为网络设备。网络设备20与终端10之间可以通过空口建立连接，从而通过该连接进行通信，包括信令和数据的交互。网络设备20的数量可以有多个，两个邻近的网络设备20之间也可以通过有线或者无线的方式进行通信。终端10可以在不同的网络设备20之间进行波束报告发送，也即与不同的网络设备20建立连接。
该网络设备20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，具备网络设备功能的设备的名称可能会有所不同，例如在5G NR(New Radio，新空口)系统中，称为gNodeB或者gNB。随着通信技术的演进，“网络设备”这一名称可能会变化。
可选地，网络设备20上设置有至少两个TRP；或者至少两个网络设备20， 每个网络设备上设置至少一个TRP，即至少两个网络设备20设置有至少两个TRP。也就是说，至少两个TRP可以来自同一个小区或不同的小区。
在一些实施例中，网络设备20上设置4个TRP，并且可以通过4个TRP为终端10提供服务，则终端可以基于4个TRP进行数据传输。
例如，若网络设备20设置了2个TRP，分别为TRP1和TRP2，参见图2和图3，终端在同一时刻同时向两个TRP传输上行数据的方案，也就是说终端在同一时刻不仅可以向TRP1传输上行数据，而且在此时刻，还可以向TRP2传输上行数据。
可选地，参见图2，终端通过一个DCI调度相同的PUSCH通过两个面板向TRP1和TRP2发送数据。参见图3，终端通过DCI 1调度的PUSCH 1由面板1向TRP1发送数据，通过DCI 2调度的PUSCH 2由面板2向TRP2发送数据。
具体的，终端向TRP传输上行数据时，还会基于开环功率控制参数和闭环功率控制参数确定上行发射功率，以便于根据确定的上行发射功率向每个TRP传输上行数据。
例如，以PUSCH(Physical Uplink Shared Channel，物理上行共享信道)的功率控制为例，对如何确定PUSCH的传输功率进行说明。其中，采用以下公式确定PUSCH的传输功率但不超过发射功率限制：
P＝P0+α×PL+f(l)+Δ
其中，f(l)为功率控制调节(power control adjustment state)值，也被称为闭环功率控制参数。其取值为f(l)＝δ(l)或者f(l，i)＝f(i-i0，l)+∑δ，具体由高层参数指示如何计算，其中δ为DCI(Downlink Control Information，下行控制信息)通过TPC(Transmission Power Control，传输功率控制)域指示的值。称为闭环功率索引(closed loop index)，i为时间，用于表示当前时刻，P0为开环接收端功率目标值，该目标接收功率为网络设备配置的期望接收功率，α为部分路损补偿因子，PL为下行路耗估计值，Δ为其他调节量。
可选地，f(i，l，t)＝f(i-i0，l，t)+∑δ，其中t为TRP的标识，δ为TPC命令指示的闭环功率调节值，i为时间，用于表示当前时刻，f(i，l，t)为累计得到的每个TRP的闭环功率调节值。

图4示出了本申请一个示例性实施例提供的功率确定方法的流程图，示例性的可以应用于如图1所示的终端和网络设备中，该方法包括以下内容中的至少部分内容：
步骤401：网络设备发送功率控制信息，功率控制信息用于指示多个面板中每个面板的功率控制参数集合，功率控制参数集合用于终端确定面板的发射功率，多个面板支持在相同的时刻按照对应的发射功率进行上行传输。
其中，该面板用于终端进行上行传输或下行传输的。面板可以理解为一组天线集合可以通过波束赋形形成方向性信号，朝一个特定的波束方向向TRP传输信息且一个面板一次只能朝一个波束方向发送信号。在一些实施例中，该面板还可以称为天线面板、用于上行传输所采用的波束、传输标识或者其他名称，本申请实施例不做限定。该传输标识用于指示终端设置的不同的用于传输的模块的标识。
其中，相同的时刻是指多个面板进行上行传输的时域资源完全重叠，或者多个面板进行上行传输的时域资源部分重叠。
该多个面板支持多个面板同时进行上行传输，也可以理解为该终端支持多个面板到多个TRP的同时上行传输。也就是说终端可以同时确定多个面板用于进行上行传输的发射功率，以便于根据确定的用于进行上行传输的发射功率进行上行传输。
在一些实施例中，该功率控制信息承载在DCI、MAC CE或RRC中，本申请实施例不做限定。
在一些实施例中，该功率控制参数信息集合包括以下至少一项：
(1)闭环功率索引。
(2)开环接收端功率目标值。
(3)部分路损补偿因子。
(4)下行路损估计值。
其中，本申请实施例中各个参数与上述实施例中的参数相同，本申请实施例不再赘述。
步骤402：终端接收功率控制信息。
本申请实施例提供的方案中，网络设备通过向终端发送功率控制信息以指示多个面板中每个面板的功率控制参数集合，则终端可以根据多个功率控制参数集合确定对应的面板的发射功率。
步骤403：终端基于功率控制信息，确定每个面板进行上行传输的发射功率。
其中，终端接收到的功率控制信息包括每个天线面板的功率控制参数集合，该功率控制参数集合用于终端确定对应天线面板的发射功率，因此终端可以根据接收的功率控制信息确定用于进行上行传输的发射功率。
需要说明的是，本申请实施例中终端所执行的步骤可以单独形成一个新的实施例，网络设备所执行的步骤也可以单独形成一个新的实施例，本申请实施例不做限定。
本申请实施例提供的方案中，提供了终端通过多个面板进行上行传输时，可以基于每个面板的功率控制参数集合确定每个天线面板的发射功率，进而根据已确定的发射功率确定每个面板进行上行传输的发射功率，以支持多个面板以合适的发射功率同时进行上行传输，进而提高传输的吞吐量且别面对其他传输产生较大的干扰。
在一些实施例中，参见图5，终端基于功率控制信息，确定每个面板进行上行传输的发射功率的过程包括以下步骤：
步骤501：终端基于功率控制信息，确定每个面板的第一发射功率。
在本申请实施例中，该功率控制信息由网络设备发送，也可以理解为功率控制信息由网络设备指示。在一些实施例中，终端基于功率控制信息确定的每个面板的第一发射功率实际上是指网络设备期望终端通过每个面板进行上行传输时所采用的发射功率。
在一些实施例中，采用下述公式确定第一发射功率：
P＝P0+α×PL+f(l)+Δ
其中，P为面板的第一发射功率，f(l)为功率控制调节(power control adjustment state)值，也被称为闭环功率控制参数。其取值为f(l)＝δ(l)或者f(l，i)＝f(i-i0，l)+∑δ，具体由高层参数指示如何计算，其中δ为DCI(Downlink Control Information，下行控制信息)通过TPC域指示的值。l称为闭环功率索引(closed loop index)，i为时间，用于表示当前时刻，P0为开环接收端功率目标值，该目标接收功率为网络设备配置的期望接收功率，α为部分路损补偿因子，PL为下行路耗估计值，Δ为其他调节量。
步骤502：终端基于每个面板的第一发射功率以及功率限制，确定每个面板进行上行传输的发射功率。
其中，该功率限制是指终端自身所受的发射功率的限制。终端通过设置该 功率限制以保证终端确定每个面板进行上行传输的发射功率不会超过功率限制。
可选地，该功率限制由通信协议约定，或者，在终端出厂时规定，或者由终端设置，或者采用其他方式设置，本申请实施例不做限定。
在一些实施例中，该功率限制是指为每个面板定义的第一功率限制，也可以理解为每个面板对应有一个第一功率限制，终端在确定面板的第一发射功率后，需要对比该面板的第一发射功率与第一功率限制，进而确定该面板进行上行传输的实际发射功率。
在一些实施例中，该功率限制是指为终端定义的总功率限制，终端在确定每个面板的第一发射功率后，需要对比所有面板的第一发射功率的和与总功率限制，进而终端确定采用面板进行上行传输的发射功率。
在一些实施例中，该功率限制包括为每个面板定义的第一功率限制和为终端定义的总功率限制，终端不仅需要对比该面板的第一发射功率与第一功率限制，而且还需要对比所有面板的第一发射功率的和与第一功率限制的和，进而终端确定采用面板进行上行传输的发射功率。
下面，终端基于每个面板的第一发射功率以及功率限制，确定每个面板进行上行传输的发射功率，包括以下任一种方式。
第一种：将每个面板的第一发射功率与每个面板对应的第一功率限制中，最小的发射功率确定为每个面板进行上行传输的发射功率。
在本申请实施例中，终端的每个面板对应有第一发射功率和第一功率限制，若第一发射功率大于第一功率限制，那终端无法提供满足要求的第一发射功率，若第一发射功率小于第一功率限制，那终端无需按照第一功率限制进行工作，因此终端将每个面板的第一发射功率与每个面板对应的功率限制中，最小的发射功率确定为每个面板进行上行传输的发射功率。
例如，面板的第一发射功率小于第一功率限制，则将该面板的第一发射功率确定为该面板进行上行传输的发射功率，若面板的第一发射功率大于第一功率限制，则将该面板的第一功率限制确定为该面板进行上行传输的发射功率。
第二种：将每个面板的第一发射功率确定为每个面板进行上行传输的发射功率。
第三种：按照多个面板的第一发射功率的比值以及总功率限制确定每个面板进行上行传输的发射功率。
其中，多个面板中每个面板均对应有第一发射功率，并且终端还具有总功 率限制，则此时会根据多个面板的第一发射功率的比值，按照比值对总功率限制进行划分，得到多个面板中每个面板进行上行传输的发射功率。
上述第三种确定每个面板进行上行传输的发射功率的方式，也可以理解为对于多个面板中的每个面板，获取该面板的第一发射功率占所有面板的第一发射功率的总和的比例，将获取的面板的比例与总功率限制的乘积确定为该面板进行上行传输的发射功率。
例如，若面板包括面板1和面板2，面板1的第一发射功率为P1，面板2的第一发射功率为P2，总功率限制为Pcmax，那么面板1进行上行传输的发射功率Ppanel1＝P1*Pcmax/(P1+P2)，Ppanel2＝P2*Pcmax/(P1+P2)。
第四种：按照面板的优先级的顺序，确定优先级较高的面板的传输功率为面板的第一发射功率与第一功率限制中的最小值，对优先级较低的面板的发射功率进行回退，以使多个面板确定的发射功率的总和不大于总功率限制。
在本申请实施例中，每个面板具有优先级，终端会按照优先级对面板进行排序，优先满足优先级高的面板的发射功率，而对于优先级低的面板，若终端无法满足总的发射功率限制，则对优先级较低的面板的发射功率进行回退。
在一些实施例中，对于所有面板中优先级最高的第一面板来说，将该第一面板的第一发射功率与第一功率限制中的最小值确定为第一面板进行上行传输的发射功率。对于所有面板中除第一面板以外的剩余面板来说，对剩余面板进行功率回退，以使已确定第一面板进行上行传输的发射功率以及剩余面板回退的发射功率的总和不大于总功率阈值。
下面，对如何确定面板的优先级进行说明。
在一些实施例中，终端通过获取各个面板的信道测量结果确定各个面板的优先级。可选地，各个面板的优先级与信道测量结果成正比。也可以理解为，面板的信道测量结果的质量越高，该面板的优先级越高。
可选地，该信道测量结果包括RSRQ(Reference Signal Receiving Quality，参考信号接收质量)、信噪比或者其他参数，本申请实施例不做限定。
在另一些实施例中，终端通过各个面板处理的业务类型确定各个面板的优先级。例如，该业务类型包括eMBB(Enhanced Mobile Broadband，增强移动宽带)和URLLC(Ultra Reliable Low Latency Communication，超可靠低延时通信)中的至少一项。该传输eMBB的面板的优先级高于传输URLLC的面板的优先级，或者，传输eMBB的面板的优先级低于传输URLLC的优先级。
在另一些实施例中，终端通过各个面板的信道类型确定各个面板的优先级。例如，该信道类型包括CG(Configured Grant，配置授权)PUSCH(Physical Uplink Shared Channel，物理上行共享信道)和DG(Dynamic Grant，周期性)PUSCH中的至少一项。传输CG PUSCH的面板的优先级高于传输DG PUSCH的面板的优先级，或者，传输CG PUSCH的面板的优先级低于传输DG PUSCH的面板的优先级。
在另一些实施例中，终端通过各个面板传输的信道的时间确定各个面板的优先级。可选地，信道的传输时间越早，该信道对应的面板的优先级越高。
对于上述四种确定面板进行上行传输的发射功率的方式，每种方式均具有执行条件，下面对每种方式所需的条件进行说明。
在一些实施例中，该功率限制为每个面板的第一功率限制，对于此种情况，存在两种条件以执行上述第一种方式。

在一些实施例中，功率限制为总功率限制，对于此情况，存在多种条件以执行上述方式中的任一种方式。
可选地，多个面板发送的为单DCI调度的PUSCH，若每个面板的第一发射功率的总和不大于总功率限制，将每个面板的第一发射功率确定为每个面板进行上行传输的发射功率。
例如，以两个面板为例进行说明，P1+P2<＝Pcmax，则发射功率Ppanel1＝P1，Ppanel2＝P2。
在一些实施例中，若多个面板的第一发射功率的总和大于总功率限制，按照多个面板的第一发射功率的比值以及总功率限制确定每个面板进行上行传输的发射功率。
需要说明的是，多个面板发送的为多个DCI调度的PUSCH，且若多个面板的第一发射功率的总和大于总功率限制，按照多个面板的第一发射功率的比值以及总功率限制确定每个面板进行上行传输的发射功率。
例如，以两个面板为例进行说明，如果P1+P2>Pcmax，按照功率的比值为两个Panel分配功率。Ppanel1＝P1*Pcmax/(P1+P2)，Ppanel2＝P2*Pcmax/(P1+P2)。

可选地，若每个面板的第一发射功率的总和大于总功率限制，按照面板的优先级的顺序，确定优先级较高的面板的传输功率为面板的第一发射功率与第一功率限制中的最小值，对优先级较低的面板的发射功率进行回退，以使多个 面板确定的发射功率的总和不大于总功率限制。
进一步地，在确定多个面板占用的时域资源存在重叠、多个面板发送的为多DCI调度的PUSCH，且终端支持在一个传输时机改变发射功率的情况下，对于重叠部分，若每个面板的第一发射功率的总和大于总功率限制，按照面板的优先级的顺序，确定优先级较高的面板的传输功率为面板的第一发射功率与第一功率限制中的最小值，对优先级较低的面板的发射功率进行回退，以使多个面板确定的发射功率的总和不大于总功率限制。
例如，以两个面板分别发送DG PUSCH和CG PUSCH为例进行说明。参见图7，TRP 1传输CG PUSCH，TRP2传输DG PUSCH，终端的多个面板发送的为多DCI调度的PUSCH，且支持在一个传输时机改变发射功率，对于重叠部分，优先保证DG-PUSCH的发射功率，而CG PUSCH由Ppanel1发送，DG PUSCH由Ppanel2发送，即Ppanel2＝min{Pcmax，P2}，如果P2<＝Pcmax，则Ppanel1＝P1-X，其中X≥P1+P2-Pcmax。如果P2>Pcmax，则P1＝0。
可选地，在终端不支持在一个传输时机改变发射功率、多个面板发送的为多DCI调度的PUSCH，且确定存在多个面板进行上行传输的情况下，若多个面板的第一发射功率的总和大于总功率限制，按照多个面板的第一发射功率的比值以及总功率限制确定每个面板进行上行传输的发射功率。
例如，以两个面板为例，终端不支持在一个传输时机改变发射功率、多个面板发送的为多DCI调度的PUSCH，且确定存在多个面板进行上行传输，如果P1+P2>Pcmax，按照功率的比值为两个Panel分配功率，Ppanel1＝P1*Pcmax/(P1+P2)，Ppanel2＝P2*Pcmax/(P1+P2)。

在一些实施例中，功率限制包括第一功率限制和总功率限制，对于此情况，存在多种条件以执行上述方式中的任一种方式。
可选地，若每个面板的第一功率限制的总和不大于总功率限制，将每个面板的第一发射功率与每个面板对应的第一功率限制中，最小的发射功率确定为每个面板进行上行传输的发射功率。
例如，以两个面板为例进行说明，Pcmax1+Pcmax2<＝Pcmax，Ppanel1＝min{Pcmax，P1}或者Ppanel2＝min{Pcmax，P2}。

可选地，若每个天线面板的第一功率限制的总和大于总功率限制，每个面 板的第一发射功率的总和大于总功率限制，终端不支持在一个传输时机改变发射功率，且多个面板发送的为多DCI调度的PUSCH，按照多个面板的第一发射功率的比值以及多个面板的第一发射功率的总和确定每个面板进行上行传输的发射功率。
例如，以两个面板为例，多个面板发送的为多DCI调度的PUSCH，终端不支持在一个传输时机改变发射功率，Pcmax1+Pcmax2>Pcmax，如果Ppanel1+Ppanel2>Pcmax，则Ppanel1＝P1*Pcmax/(P1+P2)，Ppanel2＝P2*Pcmax/(P1+P2)。
可选地，若每个面板的第一功率限制的总和大于总功率限制，每个面板的第一发射功率的总和大于总功率限制，终端不支持在一个传输时机改变发射功率，且多个面板发送的为多DCI调度的PUSCH，按照面板的优先级的顺序，基于面板的第一发射功率，依次为每个面板确定进行上行传输的发射功率，直至已确定的面板的进行上行传输的发射功率的总和达到功率限制。
例如，以两个面板分别发送DG PUSCH和CG PUSCH为例进行说明。参见图7，TRP 1传输CG PUSCH，TRP2传输DG PUSCH，多个面板发送的为多DCI调度的PUSCH，且终端不支持在一个传输时机改变发射功率，Pcmax1+Pcmax2>Pcmax，如果Ppanel1+Ppanel2>Pcmax，则Ppanel2＝min{Pcmax2，P2}，Ppanel1＝min{Pcmax-Ppanel2，P1}。
下面，对于若每个面板的第一功率限制的总和大于总功率限制，每个面板的第一发射功率的总和大于总功率限制，终端不支持在一个传输时机改变发射功率，对上述可能的结合方案进行说明。
可选地，各个面板的发射功率需要同时考虑各个panel(面板)的功率限制，还需要考虑总功率限制。先假设将每个面板的第一发射功率与每个面板对应的第一功率限制中，最小的值确定为每个面板进行上行传输的发射功率，记为各个面板的第二发射功率。然后再和总的功率限制进行对比，确定最终的发射功率。如果各个面板的发射功率小于等于总发射功率限制，则各个panel的发射功率就为假设的值；如果各个面板的发射功率大于发射功率限制按照多个面板的第一发射功率的比值以及多个面板的第一发射功率的总和确定每个面板进行上行传输的发射功率。或者按照面板的优先级的顺序，基于面板的第一发射功率，依次为每个面板确定进行上行传输的发射功率，直至已确定的面板的进行上行传输的发射功率的总和达到功率限制。
可选地，若每个面板的第一功率限制的总和大于总功率限制，且多个面板发送的为多DCI调度的PUSCH，终端不支持在一个传输时机改变发射功率的情况下，且用户不能能够确定一个panel的发射功率是确定另一个panel也有PUSCH传输。按优先级处理，比如规定先发送PUSCH具有高优先级。
本申请实施例提供的方案中，通过判断终端的面板满足不同的条件，采用不同的方式确定每个面板的发射功率，保证确定的每个面板的发射功率的准确性，进而保证终端基于面板的发射功率进行通信的可靠性。
