为便于理解本申请实施例的技术方案，以下通过具体实施例详述本申请的技术方案。以下相关技术作为可选方案与本申请实施例的技术方案可以进行任意结合，其均属于本申请实施例的保护范围。本申请实施例包括以下内容中的至少部分内容。
为便于更好的理解本申请实施例，对本申请相关的panel进行说明。
伴随着天线封装技术的不断演进，多个天线阵子(antenna element)可以与芯片嵌套结合，形成一个天线面板或者天线阵列块，这使得在发射机配置多个低相关性的panel成为可能。通过多天线的波束赋性技术，将发送信号能量汇集在某一方向上进行发送，可以有效提升覆盖，进而提高通信的性能。多个panel可以独立的形成发送波束，从而一个终端发射机可以通过不同的波束同时在多个panel上发送数据流，以提升传输的容量或可靠性。
终端设备需要在能力上报中通知网络侧所配置的天线面板的数量。同时，终端设备还可能需要通知网络侧是否具备在多个天线面板上同时传输信号的能力。由于不同panel对应的信道条件是不同的，不同的panel需要根据各自的信道信息采用不同的传输参数。为了得到这些传输参数，需要为不同的panel配置不同的探测参考信号(Sounding Reference Signal，SRS)资源来获得上行信道信息。例如，为了进行上行的波束管理，可以为每个panel配置一个SRS资源集合，从而每个panel分别进行波束管理，确定独立的模拟波束。为了得到物理上行共享信道(Physical Uplink Shared Channel，PUSCH)传输所用的预编码信息，也可以为每个panel配置一个SRS资源集合，用于得到该panel上传输的物理上行控制信道(Physical Uplink Control Channel，PUCCH)所用的波束、预编码向量、传输层数等传输参数。同时，多panel传输也可以应用于PUCCH，即同一个PUCCH资源或者同样时域资源上的PUCCH资源携带的信息可以同时通过不同的panel发送给网络侧。
为了确定传输信号所用的panel，终端可以接收网络设备配置的多个参考信号资源集合，不同参考信号资源集合采用不同的panel发送或接收参考信号。例如，网络设备可以配置多个信道状态信息参考信号(Channel State Information Reference Signal，CSI-RS)资源集合，不同集合在不同的panel上接收；或者，网络设备可以配置多个参考信号集合，不同集合在不同的panel上发送；或者，网络设备可以指示多个物理小区标识(Physical Cell Identifier，PCI)，与每个PCI关联的同步信号块(Synchronization Signal Block，SSB)作为一个集合，从而不同的集合在不同的panel上接收。此时，每个上行信号可以关联一个参考信号集合，或者被配置一个参考信号指示信息(如传输配置指示(Transmission Configuration Indicator，TCI)状态或者探测参考信号资源指示(SRS resource indicator，SRI)信息)指示一个参考信号集合中的信号，从而将关联的参考信号集合的发送或接收panel作为所述上行信号的发送panel。或者，网络设备可以给每个上行信号配置一个panel标识(Identity，ID)，根据panel ID确定上行信号的发送panel。因此，不同panel上传输的上行信号，可以称为关联不同参考信号资源集合的上行信号，或者关联不同panel ID的上行信号。此时，关联相同参考信号资源集合的上行信号，或者关联相同panel ID的上行信号，都采用相同的panel来传输。
需要说明的是，SSB也可以称为同步信号/物理广播信道块(synchronization signal/physical broadcast channel block，SS/PBCH block)。
为便于更好的理解本申请实施例，对本申请相关的上行非相干传输进行说明。
在NR系统中引入了基于多个发送接收点(Transmission Reception Point，TRP)的上行非相干传输。其中，TRP之间的回传(backhaul)连接可以是理想的或者非理想的，理想的backhaul下TRP之间可以快速动态的进行信息交互，非理想的backhaul下由于时延较大TRP之间只能准静态的进行信息交互。不同TRP同样可以独立调度同一个终端的PUSCH传输。不同PUSCH传输可以配置独立的传输参数，例如波束、预编码矩阵、层数等。所调度的PUSCH传输可以在同样的时隙或不同的时隙传输。如果终端在同一个时隙被同时调度了多个PUSCH传输，则需要根据自身能力确定如何进行传输。如果终端配置有多个panel，且支持在多个panel上同时传输PUSCH，则可以同时传输这多个PUSCH，且不同panel上传输的PUSCH对准相应的TRP进行模拟赋形，从而通过空间域区分不同的PUSCH，提供上行的频谱效率(如图2中的a)。如果终端只有单个panel，或者不支持多个panel同时传输，则只能在一个panel上传输PUSCH。
不同TRP传输的PUSCH可以基于多个下行控制信息(Downlink Control Information，DCI)进行调度，这些DCI可以通过不同的控制资源集(Control Resource Set，CORESET)来承载。具体的，网络侧配置多个CORESET组，每个TRP采用各自的CORESET组中的CORESET进行调度，即可以通过CORESET组来区分不同的TRP。例如，网络设备可以为每个CORESET配置一个CORESET组索引，不同的索引对应不同的TRP。向不同TRP传输的PUSCH也可以基于单个DCI进行调度，此时所述DCI中需要指示向不同TRP传输的PUSCH分别采用的波束和解调参考信号(Demodulation Reference Signal，DMRS)端口等参数(如图2中的b)。在这种方式下，PUSCH的不同传输层在不同的panel上采用独立的传输参数(如波束，预编码矩阵，功率控制参数等)来传输，但是调制编码方案(Modulation and Coding Scheme，MCS)和物理资源是相同的。
需要说明的是，图2为基于多panel的PUSCH传输，具体地，图2中的a基于多个DCI，图2中的b基于单个DCI。
为便于更好的理解本申请实施例，对本申请相关的上行PUSCH功率控制进行说明。
PUSCH的发送功率可以通过如下公式1计算：
Figure PCTCN2022074062-appb-000001
其中，在公式1中，P CMAX,f,c(i)是终端在服务小区c载波f上支持的最大发送功率，i是一次PUSCH传输的索引，j是开环功率控制参数索引(包括目标功率P O_PUSCH,b,f,c(j)和路损因子α b,f,c(j))；q d是用于进行路损测量的参考信号的索引，用于得到路损值PL b,f,c(q d)，也是一个开环功率控制参数；f b,f,c(i,l)是闭环功率控制调整因子，其中l是闭环功率控制进程。其中，终端设备根据网络侧发送的传输功率控制(Transmission Power Control，TPC)命令来确定闭环功率调整因子，所述TPC命令可以通过终端搜索空间中用于调度所述PUSCH的DCI来承载，也可以通过公共搜索空间中用于携带组TPC命令的DCI格式2_2来承载。
在NR系统中，终端设备基于DCI中的SRI来确定所调度的PUSCH的发送波束，也基于SRI来确定PUSCH所用的功率控制参数。具体的，网络侧预先通过无线资源控制(Radio Resource Control，RRC)信令配置多个SRI-PUSCH-PowerControl参数域，每个参数域对应一个SRI取值，参数域中包含该SRI取值对应的一组PUSCH功率控制参数配置(例如j,q d,l)。当SRI指示的值不同时，采用对应的参数域(SRI-PUSCH-PowerControl)中的功率控制参数配置来确定当前调度的PUSCH的发送功率。
为便于更好的理解本申请实施例，对本申请所解决的问题进行说明。
网络设备可以通过单个DCI调度终端在多个panel上传输PUSCH，此时PUSCH的不同传输层可以在不同的panel上传输，且发送给不同的TRP。网络设备可以为不同panel上的传输层配置不同的功率控制参数，从而保证不同传输层在不同TRP上的接收性能。由于硬件实现的不同，不同panel间的发送功率能否共享或者panel间是否需要进行协同功率分配取决于各个终端的具体实现。不同能力的终端如何进行合理的功率控制，从而保证上行多panel同时传输的性能是需要解决的问题。
基于上述问题，本申请提出了一种确定传输层的发送功率的方案，可以根据不同panel之间的功率能否共享，或者不同panel之间是否需要联合进行功率分配，从而采用相应的功率控制方式，为每个panel上的传输层确定合理的发送功率并进行相应的PHR上报，保证上行多panel同时传输的性能。

S210，终端设备接收用于调度PUSCH的下行信令；其中，该PUSCH包括多个传输层，该下行信令中包括多个SRI信息，且该多个SRI信息与该多个传输层中的不同传输层关联，或者，该下行信令中包括多个TCI状态，且该多个TCI状态与该多个传输层中的不同传输层关联；
S220，该终端设备采用目标功率控制方式确定与该多个SRI信息或者该多个TCI状态关联的传输层的发送功率；其中，该目标功率控制方式为第一功率控制方式或者第二功率控制方式，该第一功率控制方式为关联不同SRI信息或者TCI状态的传输层独立确定发送功率，该第二功率控制方式为关联不同SRI信息或者TCI状态的传输层联合确定发送功率；
S230，该终端设备根据确定的该多个传输层的发送功率，发送该多个传输层。
在本申请实施例中，“天线面板”也可以称之为“天线阵列块”，本申请对此并不限定。
在一些实施例中，该下行信令可以是DCI信令或者RRC信令(如基于PUSCH的配置授权(configured grant based PUSCH))。
在一些实施例中，该下行信令中也可以同时包括该多个SRI信息和该多个TCI状态，本申请对此并不限定。
在一些实施例中，该多个SRI信息所指示的参考信号资源属于不同的参考信号资源集合。例如，该多个SRI信息指示的SRS资源属于不同的SRS资源集合。网络设备可以预先为该PUSCH配置多个SRS资源集合，每个集合关联其中一个SRI信息。
在一些实施例中，该多个TCI状态所指示的参考信号资源属于不同的参考信号资源集合。例如，该多个TCI状态指示的CSI-RS资源属于不同的CSI-RS资源集合。网络设备可以预先为该PUSCH配置多个CSI-RS资源集合，每个集合关联其中一个TCI状态。
在一些实施例中，在该多个SRI信息中SRI信息的数量为2的情况下，该多个传输层的前一半传输层关联一个SRI信息，该多个传输层的后一半传输层关联另一个SRI信息。
具体例如，假设该多个SRI信息为2个SRI信息，该多个传输层的数量为N。具体地，该多个SRI信息与该多个传输层的关联关系为：该多个传输层的前N/2(下取整)个传输层关联一个SRI信息，该多个传输层的后N/2(上取整)个传输层关联另一个SRI信息；或者，该多个传输层的奇数层关联一个SRI信息，该多个传输层的偶数层关联另一个SRI信息。
在一些实施例中，在该多个TCI状态中TCI状态的数量为2的情况下，该多个传输层的前一半传输层关联一个TCI状态，该多个传输层的后一半传输层关联另一个TCI状态。
具体例如，假设该多个TCI状态为2个TCI状态，该多个传输层的数量为N，具体地，该多个TCI状态与该多个传输层的关联关系为：该多个传输层的前N/2(下取整)个传输层关联一个TCI状态，该多个传输层的后N/2(上取整)个传输层关联另一个TCI状态；或者，该多个传输层的奇数层关联一个TCI状态，该多个传输层的偶数层关联另一个TCI状态。
在一些实施例中，该下行信令包含两个SRI信息(第一SRI信息和第二SRI信息)，其中第一SRI信息关联第一传输层(可以是一个或多个传输层)，第二SRI信息关联第二传输层(可以是一个或多个传输层)。
其中，对于第一功率控制方式，第一传输层的发送功率根据网络设备配置的第一功率控制参数与所述第一传输层(即所在panel上的)的最大发送功率确定，与第二传输层的发送功率无关；第二传输层的发送功率根据网络设备配置的第二功率控制参数与第二传输层(即所在panel上的)的最大发送功率确定，与第一传输层的发送功率无关。
其中，对于第二功率控制方式，终端设备需要根据该PUSCH所在载波上的最大发送功率，基于第一功率控制参数计算出的第一传输层的发送功率，以及基于第二功率控制参数计算出的第二传输层的发送功率，来确定第一传输层和第二传输层的实际发送功率。即第一传输层和第二传输层的发送功率需要联合确定，在确定第一传输层的实际发送功率时，也需要考虑第二传输层的发送功率。
对于panel之间可以共享功率的终端设备，可以只限制总的发送功率，此时终端可以根据两个panel上的发送功率，将功率优先分给其中更需要功率的panel，从而达到更好的传输性能。而如果一个载波上多个panel的最大发送功率的和超过载波上支持的最大发送功率，也需要采用第二功率控制方式在多个panel的传输层之间分配功率。
在一些实施例中，该终端设备根据其终端能力从该第一功率控制方式和该第二功率控制方式中确定该目标功率控制方式。
在一些实现方式中，在该终端设备的不同天线面板之间不能共享发送功率的情况下，该终端设备确定该目标功率控制方式为该第一功率控制方式；和/或，在该终端设备的不同天线面板之间允许共享发送功率的情况下，该终端设备确定该目标功率控制方式为该第二功率控制方式。可选地，该终端设备的不同天线面板之间是否能共享发送功率可以上报给网络设备，从而网络设备可以获知该终端设 备采用的功率控制方式。
在另一些实现方式中，如果终端设备的不同panel之间不能共享功率，则采用第一功率控制方式；如果终端的不同panel之间可以共享功率，则可以采用第一功率控制方式或者第二功率控制方式。具体采用哪种方式可以由网络设备配置或者由终端设备确定后上报给网络设备。
在另一些实现方式中，在该终端设备在该PUSCH所在载波上的多个天线面板上支持的最大发送功率之和不超过该载波上支持的最大发送功率的情况下，该终端设备确定该目标功率控制方式为该第一功率控制方式；和/或，在该终端设备在该PUSCH所在载波上的多个天线面板上支持的最大发送功率之和超过该载波上支持的最大发送功率的情况下，该终端设备确定该目标功率控制方式为该第二功率控制方式。
具体例如，如果终端设备在该PUSCH所在载波上的多个panel上支持的最大发送功率之和不超过所述载波上支持的最大发送功率，则采用第一功率控制方式。如果终端设备在该PUSCH所在载波上的多个panel上支持的最大发送功率之和超过所述载波上支持的最大发送功率，则采用第二功率控制方式。假设第一panel上支持的最大发送功率为P c,1,max，第二panel上支持的最大发送功率为P c,2,max，终端在所述载波上支持的最大发送功率为P c,max，则当P c,1,max+P c,2,max<＝P c,max，采用第一功率控制方式；当P c,1,max+P c,2,max>P c,max，采用第二功率控制方式。
在一些实施例中，该终端设备根据网络设备发送的第一指示信息，从该第一功率控制方式和该第二功率控制方式中确定该目标功率控制方式。可选地，该第一指示信息可以通过高层信令承载。
例如，网络设备通过高层信令指示终端设备当前使用的功率控制方式。又例如，终端设备默认只能采用第一功率控制方式，网络设备可以通过下行信令来使能第二功率控制方式，当终端设备接收到该信令后则使用第二功率控制方式。
在一些实施例中，在该终端设备接收该第一指示信息之前，该终端设备向该网络设备发送第一能力信息，其中，该第一能力信息用于指示该终端设备的不同天线面板之间是否允许共享发送功率。
具体地，该网络设备可以根据该第一能力信息确定采用哪种功率控制方式。如果该第一能力信息指示可以共享功率，则网络设备可以配置第二功率控制方式或者第一功率控制方式，或者只能配置第二功率控制方式(此时终端设备不期望网络设备配置第一功率控制方式)；如果该第一能力信息指示不能共享功率，则网络设备只能配置第一功率控制方式(此时终端设备不期望网络设备配置第二功率控制方式)。
在一些实施例中，在该终端设备接收该第一指示信息之前，该终端设备向该网络设备发送第二能力信息；其中，该第二能力信息用于指示以下至少之一：该终端设备在一个载波的每个天线面板上支持的最大发送功率，该终端设备在每个天线面板上支持的最大总发送功率，该终端设备在一个载波上支持的最大发送功率，该终端设备在所有天线面板上支持的最大总发送功率。
具体例如，这里一个panel上支持的最大总发送功率是指一个panel在所有载波上支持的总的最大发送功率，终端设备在所有panel上支持的最大总发送功率是终端设备在所有panel和所在载波上能够支持的最大的总的发送功率，也就是终端设备支持的最大发送功率(即由终端设备的功率等级(power class)确定的发送功率)。该第二能力信息可以用于第一功率控制方式下终端设备计算关联不同SRI信息(或TCI状态)的传输层的发送功率。
在一些实现方式中，该第二能力信息可以和该第一能力信息一起上报给网络。
在一种实现方式中，当该终端设备上报的该第一能力信息指示终端设备的不同panel之间不能共享功率时，终端设备才上报该第二能力信息。
在一些实施例中，示例1，在该目标功率控制方式为该第一功率控制方式的情况下，上述S220具体可以包括：

该终端设备根据该多个TCI状态各自对应的功率控制参数，以及该PUSCH所在载波上的每个天线面板支持的最大发送功率，确定该多个TCI状态各自对应的发送功率；以及该终端设备将该多个TCI状态各自对应的发送功率平均分到每个TCI状态各自关联的传输层。
在一些实施例中，示例2，在该目标功率控制方式为该第二功率控制方式的情况下，上述S220具体可以包括：
终端设备根据该多个SRI信息各自对应的功率控制参数和该PUSCH所在载波上支持的最大发送功率，确定该多个SRI信息各自对应的预期发送功率；以及该终端设备根据该载波上支持的最大发送功率和该多个SRI信息各自对应的预期发送功率，确定关联不同SRI信息的传输层的发送功率；或者，
终端设备根据该多个TCI状态各自对应的功率控制参数和该PUSCH所在载波上支持的最大发送功率，确定该多个TCI状态各自对应的预期发送功率；以及该终端设备根据该PUSCH所在载波上支持的最大发送功率和该多个TCI状态各自对应的预期发送功率，确定关联不同TCI状态的传输层的发送功率。
在一些实现方式中，在示例2中，在该多个SRI信息对应的预期发送功率之和超过该PUSCH所在载波上支持的最大发送功率的情况下，该终端设备根据第一预设规则降低该多个SRI信息中的至少一个SRI信息对应的预期发送功率，其中，功率降低之后的该多个SRI信息对应的发送功率之和不超过该PUSCH所在载波上支持的最大发送功率；以及该终端设备将降低之后的该多个SRI信息中每个SRI信息各自对应的发送功率平均分到每个SRI信息各自关联的传输层。

若该多个TCI状态中的第一TCI状态关联的传输层中包含HARQ-ACK信息或者CSI，该多个TCI状态中的第二TCI状态关联的传输层中不包含HARQ-ACK信息或CSI，则降低该第二TCI状态对应的发送功率；
以相同比例降低该多个SRI信息或者该多个TCI状态对应的发送功率；
以相同的功率值降低该多个SRI信息或者该多个TCI状态对应的发送功率。
在一些实现方式中，该第一预设规则至少包括：降低该多个SRI信息或该多个TCI状态对应的发送功率中最低的发送功率。具体例如，降低该多个SRI信息或该多个TCI状态对应的发送功率中最低的发送功率，即较高的发送功率不变，从而保证至少部分传输层的传输可靠性。进一步的，如果降低功率后最低的发送功率达到一定的门限值，则不再继续降低该发送功率，而是降低次低的发送功率，从而保证每个SRI信息或TCI状态对应的发送功率都有一个能够支持传输的最小值。
在一些实现方式中，该第一预设规则至少包括：降低该多个SRI信息或该多个TCI状态对应的发送功率中最高的发送功率。具体例如，降低该多个SRI信息或该多个TCI状态对应的发送功率中最高的发送功率，即较低的发送功率不变，从而保证所有层的传输性能相当。进一步的，如果最高的发送功率降低到与另一个SRI信息或TCI状态对应的发送功率相同后，以相同的比例或者相同的功率值降低这两个SRI信息或TCI状态对应的发送功率。例如，第一发送功率降低到与第二发送功率相同后，如果仍需要降低发送功率，则这两个发送功率同时降低，保证功率降低后第一发送功率不会不低于第二发送功率，即永远只降低当前最高的发送功率。
在一些实现方式中，该第一预设规则至少包括：若该多个SRI信息中的第一SRI信息关联的传输层中包含HARQ-ACK信息或者CSI，该多个SRI信息中的第二SRI信息关联的传输层中不包含HARQ-ACK信息或CSI，则降低该第二SRI信息对应的发送功率。具体例如，如果第一SRI信息关联的传输层中包含HARQ-ACK信息或者CSI，第二SRI信息关联的传输层中不包含HARQ-ACK信息和CSI，则降低第二SRI信息对应的发送功率。
例如，如果第一SRI信息关联的传输层中包含HARQ-ACK信息，第二SRI信息关联的传输层中不包含HARQ-ACK信息，则降低第二SRI信息对应的发送功率。

例如，如果第一TCI状态关联的传输层中包含HARQ-ACK信息，第二TCI状态关联的传输层中不包含HARQ-ACK信息，则降低第二TCI状态对应的发送功率。
又例如，如果第一TCI状态关联的传输层中包含CSI，第二TCI状态关联的传输层中不包含CSI，则降低第二TCI状态对应的发送功率。
在一些实现方式中，该第一预设规则至少包括：以相同比例降低该多个SRI信息或者该多个TCI状态对应的发送功率。具体例如，以相同比例降低该多个TCI状态对应的发送功率。
具体的，假设多个panel的预期发送功率分别为P1和P2，终端设备在该PUSCH所在载波上支持的最大发送功率为P max。在P1+P2>P max且多个panel上的信号优先级相同的情况下，等比例降低该多个panel上的功率分别为：P1*P max/(P1+P2)和P2*P max/(P1+P2)。
在一些实现方式中，该第一预设规则至少包括：以相同的功率值降低该多个SRI信息或者该多个TCI状态对应的发送功率。具体例如，以相同的功率值降低该多个TCI状态对应的发送功率。
具体的，假设该PUSCH当前的发送功率为P 2，目标发送功率为P 3(P 3<P 2)，该DCI中包含K个TCI状态，则每个TCI状态对应的发送功率需要降低(P 3-P 2)/K。
在一些实施例中，在降低发送功率之后该多个SRI信息中的一个SRI信息关联的传输层的发送功率低于预设的第一门限值的情况下，该终端设备不发送该PUSCH，或者，该终端设备不发送与该一个SRI信息关联的传输层。
在一些实现方式中，在降低发送功率之后该多个TCI状态中的一个TCI状态关联的传输层的发送功率低于预设的第一门限值的情况下，该终端设备不发送该PUSCH，或者，该终端设备不发送与该一个TCI状态关联的传输层。

以下通过实施例1至实施例3详述本申请技术方案。
实施例1，具体可以通过S11至S14确定传输层的发送功率并发送传输层。
S11，终端设备接收用于调度PUSCH的下行信令。
其中，该下行信令可以是DCI信令或者RRC信令(如基于PUSCH的配置授权(configured grant based PUSCH))。本实施例以DCI信令为例。
其中，该下行信令中包含多个SRI信息或者多个TCI状态，本实施例中以多个SRI信息为例(下面的描述中的SRI信息也可以替换为TCI状态)。该PUSCH包含多个传输层(这里假设为N>1个传输层)，该多个SRI信息与该多个传输层中的不同传输层关联(即不同的SRI信息关联不同的传输层)。
具体的，SRI信息与传输层的关联关系可以由网络设备配置给终端设备，或者，SRI信息与传输层的关联关系可以由终端设备与网络设备预先约定好。
在一些实现方式中，假设该多个SRI信息为2个SRI信息，该多个SRI信息与该多个传输层的关联关系为：该多个传输层的前N/2(下取整)个传输层关联一个SRI信息，该多个传输层的后N/2(上取整)个传输层关联另一个SRI信息。
在一些实现方式中，也可以采用其他的关联方式，比如该多个传输层的奇数层关联一个SRI信息， 该多个传输层的偶数层关联另一个SRI信息。
在一些实现方式中，该多个SRI信息所指示的参考信号资源属于不同的参考信号资源集合。例如，该多个SRI信息指示的SRS资源属于不同的SRS资源集合。网络设备可以预先为该PUSCH配置多个SRS资源集合，每个集合关联其中一个SRI信息。
S12，终端设备根据网络设备的指示信息或者根据自己的UE能力，确定采用第一功率控制方式还是第二功率控制方式确定与该多个SRI信息关联的传输层的发送功率。
其中，该第一功率控制方式为关联不同SRI信息的传输层独立确定发送功率，该第二功率控制方式为关联不同SRI信息的传输层联合确定发送功率。
具体的，假设该DCI包含两个SRI信息(第一SRI信息和第二SRI信息)，其中第一SRI信息关联第一传输层，第二SRI信息关联第二传输层。
其中，对于第一功率控制方式，第一传输层的发送功率根据网络设备配置的第一功率控制参数与所述第一传输层(即所在panel上的)的最大发送功率确定，与第二传输层的发送功率无关；第二传输层的发送功率根据网络设备配置的第二功率控制参数与第二传输层(即所在panel上的)的最大发送功率确定，与第一传输层的发送功率无关。
其中，对于第二功率控制方式，终端设备需要根据该PUSCH所在载波上的最大发送功率，基于第一功率控制参数计算出的第一传输层的发送功率，以及基于第二功率控制参数计算出的第二传输层的发送功率，来确定第一传输层和第二传输层的实际发送功率。即第一传输层和第二传输层的发送功率需要联合确定，在确定第一传输层的实际发送功率时，也需要考虑第二传输层的发送功率。
对于panel之间可以共享功率的终端设备，可以只限制总的发送功率，此时终端可以根据两个panel上的发送功率，将功率优先分给其中更需要功率的panel，从而达到更好的传输性能。而如果一个载波上多个panel的最大发送功率的和超过载波上支持的最大发送功率，也需要采用第二功率控制方式在多个panel的传输层之间分配功率。
在一种实施方式中，终端设备可以根据自身的终端能力确定功率控制方式。
具体的，如果终端设备的不同panel之间不能共享功率，则采用第一功率控制方式；如果终端设备的不同panel之间可以共享功率，则采用第二功率控制方式。该终端能力可以上报给网络设备，从而网络设备可以获知当前终端采用的功率控制方式。
在另一种实现中，如果终端设备的不同panel之间不能共享功率，则采用第一功率控制方式；如果终端的不同panel之间可以共享功率，则可以采用第一功率控制方式或者第二功率控制方式，具体采用哪种方式可以由网络设备配置或者由终端设备确定后上报给网络设备。
在另一种实现中，如果终端设备在该PUSCH所在载波上的多个panel上支持的最大发送功率之和不超过所述载波上支持的最大发送功率，则采用第一功率控制方式。如果终端设备在该PUSCH所在载波上的多个panel上支持的最大发送功率之和超过所述载波上支持的最大发送功率，则采用第二功率控制方式。假设第一panel上支持的最大发送功率为P c,1,max，第二panel上支持的最大发送功率为P c,2,max，终端在所述载波上支持的最大发送功率为P c,max，则当P c,1,max+P c,2,max<＝P c,max，采用第一功率控制方式；当P c,1,max+P c,2,max>P c,max，采用第二功率控制方式。
在另一种实施方式中，终端设备可以根据网络设备的指示信息确定功率控制方式。
例如，网络设备通过高层信令指示终端设备当前使用的功率控制方式。又例如，终端设备默认只能采用第一功率控制方式，网络设备可以通过下行信令来使能第二功率控制方式，当终端设备接收到该信令后则使用第二功率控制方式。
在此之前，终端设备还需要向网络设备上报第一UE能力，该第一UE能力用于指示终端设备的不同panel之间是否可以共享功率，网络设备可以根据终端设备的能力上报确定采用哪种功率控制方式。如果该第一UE能力指示可以共享功率，则网络设备可以配置第二功率控制方式或者第一功率控制方式，或者只能配置第二功率控制方式(此时终端不期望网络设备配置第一功率控制方式)；如果所述第一UE能力指示不能共享功率，则网络设备只能配置第一功率控制方式(此时终端不期望网络设备配置第二功率控制方式)。
另外，终端设备还可以进一步向网络设备上报第二UE能力，该第二UE能力用于指示以下至少之一：终端设备在一个载波的每个panel上支持的最大发送功率，终端设备在每个panel上支持的最大总发送功率，终端设备在一个载波上支持的最大发送功率，终端在所有panel上支持的最大总发送功率。这里一个panel上支持的最大总发送功率是指一个panel在所有载波上支持的总的最大发送功率，终端在所有panel上支持的最大总发送功率是终端在所有panel和所在载波上能够支持的最大的总的发送功率，也就是终端支持的最大发送功率(即由终端的功率等级(power class)确定的发送功率)。第二UE能力可以用于第一功率控制方式下终端计算关联不同SRI信息的传输层的发送功率。
在一些实现方式中，该第二UE能力可以和该第一UE能力一起上报给网络。
在一种实现方式中，当终端设备上报的第一UE能力指示终端的不同panel之间不能共享功率时，终端设备才上报第二UE能力。
S13，终端设备采用确定的功率控制方式得到与该多个SRI信息关联的传输层的发送功率。
该方法进一步包括，终端设备根据确定的发送功率，计算该多个SRI信息关联的传输层的PH值，并进行PHR上报。具体的，终端设备可以根据所采用的功率控制方式，进行与不同SRI信息关联的传输层的PHR上报。也就是说，针对不同的功率控制方式，相应的PH值计算公式可以不同。
在一种实现方式中，如果终端设备采用第一功率控制方式进行功率控制，则可以基于该PUSCH所在载波上每个panel上支持的最大发送功率，以及与每个SRI信息关联的传输层的发送功率，计算传输层的PH值；进一步的，终端设备可以分别上报该多个SRI信息关联的传输层的PHR。也就是说，终端设备可以为每个SRI信息关联的传输层计算一个PH值，并分别上报这些PH值。
在另一种实现方式中，如果终端设备采用第二功率控制方式，则可以基于PUSCH所在载波上支持的最大发送功率，以及与每个SRI信息关联的传输层的发送功率，计算传输层的PH值；进一步的，终端设备可以分别上报该多个SRI信息关联的传输层的PHR。
S14，终端设备根据确定的发送功率，发送该多个传输层。
实施例2，具体可以通过S21至S23确定传输层的发送功率并发送传输层。
S21，终端设备接收用于调度PUSCH的DCI，该DCI中包含多个SRI信息或者多个TCI状态。
本实施例中以多个TCI状态为例。可选的，本实施例中下面的描述中的TCI状态也可以替换为SRI信息，即相应的方法也可以应用于SRI信息。
在本实施例中，该PUSCH包含多个传输层(这里假设为N>1个传输层)，该多个TCI状态与该多个传输层中的不同传输层关联(即不同的TCI状态关联不同的传输层)。
其中，该多个TCI状态所指示的参考信号资源属于不同的参考信号资源集合。例如，该多个TCI状态指示的SRS资源属于不同的SRS资源集合。网络设备可以预先为该PUSCH配置多个SRS资源集合，每个集合关联其中一个TCI状态。又例如，该TCI状态指示CSI-RS资源，该多个TCI状态指示的CSI-RS资源属于不同的CSI-RS资源集合
需要说明的是，关联关系可以参考上述实施例1的描述，在此不再赘述。
S22，终端设备采用第一功率控制方式确定与该多个TCI状态关联的传输层的发送功率；
其中，第一功率控制方式为关联不同TCI状态的传输层独立确定发送功率。具体的，假设该DCI包含两个TCI状态(第一TCI状态和第二TCI状态)，其中第一TCI状态关联第一传输层，第二TCI状态关联第二传输层(本实施例后续的描述都以这个假设为例说明)。该第一传输层的发送功率根据与该第一TCI状态对应的第一功率控制参数以及该第一传输层(即其所在panel上的)的最大发送功率确定，与第二传输层的发送功率无关；该第二传输层的发送功率根据与该第二TCI状态对应的第二功率控制参数以及第二传输层(即其所在panel上的)的最大发送功率确定，与第一传输层的发送功率无关。
在一种实施方式中，终端设备根据该多个TCI状态各自对应的功率控制参数，以及该PUSCH所在载波上每个panel上支持的最大发送功率，确定该多个TCI状态各自对应的发送功率。进一步的，终端设备将确定的每个TCI状态各自对应的发送功率平均分到该TCI状态关联的传输层上。
例如，假设根据第一TCI状态对应的第一功率控制参数确定的发送功率为P 1，根据第二TCI状态对应的第二功率控制参数确定的发送功率为P 2，终端设备在该PUSCH所在载波上每个panel上支持的最大发送功率为P c,p,max。则该第一TCI状态关联的第一传输层的总发送功率(即第一TCI状态对应的发送功率)为P 1,a＝min(P c,p,max,P 1)，该第二TCI状态关联的第二传输层的总发送功率(即第二TCI状态对应的发送功率)为P 2,a＝min(P c,p,max,P 2)。进一步的，终端设备将P 1,a平均分到第一传输层上，并将P 2,a平均分到第二传输层上。如果有n个层，每个层的发送功率线性值为总功率的1/n。
在一种实现方式中，终端设备在该PUSCH所在载波上的多个panel上支持的最大发送功率的和，等于该PUSCH所在载波上支持的最大发送功率。例如，终端设备有两个panel，第一panel上支持的最大发送功率为P c,1,max，第二panel上支持的最大发送功率为P c,2,max，终端设备在该PUSCH所在载波上支持的最大发送功率为P c,max，则有P c,1,max+P c,2,max＝P c,max。
在另一种实现方式中，终端设备在该PUSCH所在载波上的多个panel上支持的最大发送功率的和，也可以小于或等于该PUSCH所在载波上支持的最大发送功率，即P c,1,max+P c,2,max<＝P c,max。
在一种实施方式中，该DCI中还包括多个TPC命令，该多个TPC命令与该多个SRI信息一一对应，该多个TPC命令用于指示对应的SRI信息关联的传输层的闭环功率调整值。例如，该DCI中包含第一TPC命令和第二TPC命令，第一TPC命令与第一TCI状态对应，用于指示第一传输层的闭环 功率调整值；第二TPC命令与第二TCI状态对应，用于指示第二传输层的闭环功率调整值。
在一种实施方式中，关联相同TCI状态或者相同PTRS端口的传输层采用相同的发送功率。例如，每个TCI状态可以对应一个PTRS端口，从而关联相同PTRS端口的传输层即为关联相同TCI状态的传输层，可以采用相同的发送功率。
S23，终端设备根据确定的发送功率，发送该多个传输层。
具体的，终端设备在不同的panel上发送与不同TCI状态关联的传输层。例如，终端在第一panel上发送与第一TCI状态关联的第一传输层，在第二panel上发送与第二TCI状态关联的第二传输层。
该方法进一步包括，终端设备根据确定的发送功率，计算该传输层的PH值，并进行PHR上报。
具体的，终端设备可以基于该PUSCH所在载波上每个panel上支持的最大发送功率，以及与每个TCI状态关联的传输层的发送功率，计算该传输层的PH值；进一步的，终端可以分别上报该多个TCI状态关联的传输层的PHR。
例如，假设第一TCI状态关联的第一传输层的发送功率为P 1，第二TCI状态关联的第二传输层的发送功率为P 2，终端设备在该PUSCH所在载波c上每个panel上支持的最大发送功率为P c,p,max，则第一传输层对应的PH值为P c,p,max-P 1，第二传输层对应的PH值为P c,p,max-P 2。
实施例2，具体可以通过S31至S33确定传输层的发送功率并发送传输层。
S31，终端设备接收用于调度PUSCH的DCI，该DCI中包含多个SRI信息或者多个TCI状态。
本实施例中以多个TCI状态为例。可选的，本实施例中下面的描述中的TCI状态也可以替换为SRI信息，即相应的方法也可以应用于SRI信息。该PUSCH包含多个传输层(这里假设为N>1个传输层)，该多个TCI状态与该多个传输层中的不同传输层关联(即不同的TCI状态关联不同的传输层)。
需要说明的是，关联关系可以参考实施例1的描述，在此不再赘述。
S32，终端设备采用第二功率控制方式确定与该多个TCI状态关联的传输层的发送功率；
具体的，第二功率控制方式为关联不同TCI状态的传输层联合确定发送功率。
具体的，假设该DCI包含两个TCI状态(第一TCI状态和第二TCI状态)，其中第一TCI状态关联第一传输层，第二TCI状态关联第二传输层(本实施例后续的描述都以这个假设为例说明)。其中第一传输层在第一panel上传输，第二传输层在第二panel上传输。
终端设备可以根据与该第一TCI状态对应的第一功率控制参数以及该PUSCH所在载波上的最大发送功率，确定该第一传输层的预期发送功率，根据与该第二TCI状态对应的第二功率控制参数以及该PUSCH所在载波上的最大发送功率，确定该第二传输层的预期发送功率。
进一步的，终端设备可以基于第一传输层和第二传输层的预期发送功率，以及该PUSCH所在载波上支持的最大发送功率，联合确定第一传输层和第二传输层的实际发送功率。也就是说，第一传输层和第二传输层的发送功率需要联合确定，终端设备可以在第一传输层和第二传输层之间(也就是在第一panel和第二panel之间)进行功率分配。
在本实施例中，对于panel之间可以共享功率的终端设备，可以只限制总的发送功率，此时终端设备可以根据两个panel上的预期发送功率，在两个panel上信号之间进行功率分配，将功率优先分给其中更需要功率的panel，从而达到更好的传输性能。
在一种实施方式中，终端设备根据该多个TCI状态各自对应的功率控制参数，以及该PUSCH所在载波上支持的最大发送功率，确定该多个TCI状态各自对应的预期发送功率。进一步的，终端设备根据该PUSCH所在载波上支持的最大发送功率，以及该多个TCI状态各自对应的预期发送功率，确定关联不同TCI状态的传输层的发送功率。具体，可以有以下三个方法：
方法1：如果该多个TCI状态对应的预期发送功率的和超过该载波上支持的最大发送功率，则终端设备根据第一预设规则降低其中至少一个TCI状态对应的发送功率，以使该多个TCI状态对应的发送功率的和不超过该PUSCH所在载波上支持的最大发送功率；进一步的，终端设备将该发送功率平均分到每个TCI状态各自关联的传输层。
这里以两个TCI状态为例进行说明，假设第一TCI状态对应的预期发送功率为P 1，第二TCI状态对应的预期发送功率为P 2，终端设备在该PUSCH所在载波上支持的最大发送功率为P c,max。在P 1+P 2>P c,max的情况下(这里假设功率均为线性值)，终端设备可以根据第一预设规则，降低第一TCI状态或者第二TCI状态对应的发送功率，从而使降低功率后的P 1+P 2＝P c,max。
进一步的，终端设备将P 1平均分到第一传输层上，并将P 2平均分到第二传输层上。例如，假设第一传输层包含n个传输层，则每个层的发送功率线性值为第一TCI状态对应的发送功的1/n。
方法2：终端设备将该多个TCI状态对应的预期发送功率和该PUSCH所在载波上支持的最大发送功率中的最小值，确定为该PUSCH的实际发送功率，并将该实际发送功率平均分到该PUSCH包含的所有传输层中。
假设第一TCI状态对应的预期发送功率为P 1，第二TCI状态对应的预期发送功率为P 2，终端设备在该PUSCH所在载波上支持的最大发送功率为P c,max，则该PUSCH的实际发送功率为min(P 1,P 2,P c,max)。
方法3：终端设备将该多个TCI状态对应的预期发送功率中的最大值，与该PUSCH所在载波上支持的最大发送功率之间的较小值，确定为该PUSCH的实际发送功率，并将该实际发送功率平均分到该PUSCH包含的所有传输层中。
假设第一TCI状态对应的预期发送功率为P 1，第二TCI状态对应的预期发送功率为P 2，终端设备在该PUSCH所在载波上支持的最大发送功率为P c,max，则该PUSCH的实际发送功率为min(max(P 1,P 2),P c,max)。
在一些实现方式中，该第一预设规则包括以下5种规则中的至少之一：
(1)降低该多个TCI状态对应的发送功率中最低的发送功率，即较高的发送功率不变，从而保证至少部分传输层的传输可靠性。
进一步的，如果降低功率后最低的发送功率达到一定的门限值，则不再继续降低该发送功率，而是降低次低的发送功率，从而保证每个TCI状态对应的发送功率都有一个能够支持传输的最小值。
(2)降低该多个TCI状态对应的发送功率中最高的发送功率，即较低的发送功率不变，从而保证所有层的传输性能相当。
进一步的，如果最高的发送功率降低到与另一个TCI状态对应的发送功率相同后，以相同的比例或者相同的功率值降低这两个TCI状态对应的发送功率。
例如，第一发送功率降低到与第二发送功率相同后，如果仍需要降低发送功率，则这两个发送功率同时降低，保证功率降低后第一发送功率不会不低于第二发送功率，即永远只降低当前最高的发送功率。
(3)如果第一TCI状态关联的传输层中包含HARQ-ACK信息或者CSI，第二TCI状态关联的传输层中不包含HARQ-ACK信息和CSI，则降低第二TCI状态对应的发送功率。
在一些实现方式中，如果第一TCI状态关联的传输层中包含HARQ-ACK信息，第二TCI状态关联的传输层中不包含HARQ-ACK信息，则降低第二TCI状态对应的发送功率。
在另一些实现方式中，如果第一TCI状态关联的传输层中包含CSI，第二TCI状态关联的传输层中不包含CSI，则降低第二TCI状态对应的发送功率。
(4)以相同比例降低该多个TCI状态对应的发送功率。
具体的，假设多个panel的预期发送功率分别为P1和P2，终端在该载波上支持的最大发送功率为P max。在P1+P2>P max且多个panel上的信号优先级相同的情况下，等比例降低该多个panel上的功率分别为：P1*P max/(P1+P2)和P2*P max/(P1+P2)。
(5)以相同的功率值降低该多个TCI状态对应的发送功率。
具体的，假设该PUSCH当前的发送功率为P 2，目标发送功率为P 3(P 3<P 2)，该DCI中包含K个TCI状态，则每个TCI状态对应的发送功率需要降低(P 3-P 2)/K。
在本实施例中，如果降低发送功率后一个TCI状态关联的传输层的发送功率低于预设的第一门限值，则不发送该PUSCH，或者不发送与该TCI状态关联的传输层。
例如，如果第一TCI状态的发送功率低于第一门限值，则不发送第一TCI状态关联的传输层，第二TCI状态关联的传输层可以传输或者不传输。
具体的，该第一门限值由网络设备配置，或者，该第一门限值由终端设备通过UE能力上报给网络设备。
具体的，该第一门限值可以是发送功率的绝对值(例如X dBm)，或者，该第一门限值是发送功率相对于一个载波上支持的最大发送功率的比值(即0和1之间的数值)。
在一种实施方式中，该DCI中还包括多个TPC命令，该多个TPC命令与该多个SRI信息一一对应，该多个TPC命令用于指示对应的SRI信息关联的传输层的闭环功率调整值。例如，该DCI中包含第一TPC命令和第二TPC命令，第一TPC命令与第一TCI状态对应，用于指示第一传输层的闭环功率调整值；第二TPC命令与第二TCI状态对应，用于指示第二传输层的闭环功率调整值。
S33，终端设备根据确定的发送功率，发送该多个传输层。
具体的，终端设备在不同的panel上发送与不同TCI状态关联的传输层。例如，终端设备在第一panel上发送与第一TCI状态关联的第一传输层，在第二panel上发送与第二TCI状态关联的第二传输层。
该方法进一步包括，终端设备根据确定的发送功率，计算该传输层的PH值，并进行PHR上报。
具体的，终端设备可以基于该PUSCH所在载波上支持的最大发送功率，以及与每个TCI状态关 联的传输层的发送功率，计算该传输层的PH值；进一步的，终端设备可以分别上报该多个TCI状态关联的传输层的PHR。
例如，假设第一TCI状态关联的第一传输层的发送功率为P 1，第二TCI状态关联的第二传输层的发送功率为P 2，终端设备在该PUSCH所在载波上支持的最大发送功率P c,max，则第一传输层对应的PH值为P c,max-P 1，第二传输层对应的PH值为P c,max-P 2。
