应当理解，尽管在本申请可能采用术语第一、第二、第三等来描述各种信息，但这些信息不应限于这些术语。这些术语仅用来将同一类型的信息彼此区分开。例如，在不脱离本申请范围的情况下，第一信息也可以被称为第二信息，类似地，第二信息也可以被称为第一信息。取决于语境，例如，在此所使用的词语“如果”可以被解释成为“在……时”或“当……时”或“响应于确定”。
需要说明的是，本申请所涉及的信息(包括但不限于用户设备信息、用户个人信息等)、数据(包括但不限于用于分析的数据、存储的数据、展示的数据等)以及信号，均为经用户授权或者经过各方充分授权的，且相关数据的收集、使用和处理需要遵守相关国家和地区的相关法律法规和标准。
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(Transmission Reception Point,传输接收节点)；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2，2个TRP可以采用时分的传输方式进行数据传输。其中，时分的传输方式是指在某个时刻，终端向TRP1传输上行数据，在另一个时刻，终端向TRP2传输上行数据。
目前，提出了一种支持终端在同一时刻同时向多个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。
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：
P＝min{P CMAX，P 0+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-i 0，l)+Σδ，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称为闭环索引(closed loop index)，i为时间，用于表示当前时刻，P CMAX为终端允许的最大发射功率，P 0为目标接收功率，该目标接收功率为网络设备配置的期望接收功率，α为部分路径补偿因子，PL为路径损耗，Δ为其他调节量。
本申请实施例中的“5G NR系统”也可以称为5G系统或者NR系统，但本领域技术人员可以理解其含义。本申请实施例描述的技术方案可以适用于5G NR系统，也可以适用于5G NR系统后续的演进系统。
图3示出了本申请一个示例性实施例提供的闭环功率调节值确定方法的流程图，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301：网络设备向终端发送TPC命令，TPC命令用于为终端配置多个TRP的闭环功率调节值，每个TRP对应的TPC命令对应的闭环功率调节值用于确定终端到TRP对应的上行发射功率。
步骤302：终端接收网络设备发送的TPC命令。
在本申请实施例中，终端可以通过网络设备配置的TRP进行上行数据传输。而对于终端来说，终端可以在同一时刻向网络设备传输上行数据，则对于终端来说，终端需要确定每个TRP对应的闭环功率调节值，进而基于确定的每个TRP对应的上行发射功率进行上行数据传输。
在一些实施例中，该闭环功率调节值确定上行发射功率的方式请参见上述实施例中的确定传输功率的方式。
网络设备可以通过TPC命令为终端配置多个TRP的闭环功率调节值，则终端在接收该TPC命令后，即可确定每个TRP的闭环功率调节值，进而基于每个TRP对应的TPC命令对应的闭环功率调节值确定终端到TRP对应的上行发射功率，以便于终端基于每个TRP对应的上行发射功率向网络设备发送上行数据。
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可以单独形成一个新的实施例，本申请实施例不作限定。
本申请实施例提供的方案中，终端根据TPC命令即可确定每个TRP对应的闭环功率调节值，进而终端基于每个TRP对应的闭环功率调节值以及终端到各个TRP的实际情况，进行动态发射功率调节，以便于在保证减小干扰前提下，保证终端以较大的发送功率进行上行传输，以保证系统吞吐量。
图3所示实施例对终端需要确定每个TRP的闭环功率调节值进行说明。下面，对终端具体如何根据TPC命令确定每个TRP的闭环功率调节值进行说明。
在一些实施例中，每个TRP的闭环功率调节值由TRP对应的TPC命令指示的闭环功率调节值累计得到。
在本申请实施例中，终端需要确定每个TRP的闭环功率调节值，而每个TRP的闭环功率调节值由该终端在多个时刻对应的闭环功率调节值进行累计得到。也就是说，终端需要对每个TRP对应的TPC命令指示的闭环功率调节值进行累计，得到当前时刻每个TRP的闭环功率调节值。
可选地，f(il，t)＝f(i-i 0，l，t)+Σδ，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。
例如，如图4所示，终端会对Δt内所有属于同一closed loop processes(闭环流程)的TPC命令指示的闭环功率调节值进行累计，以得到累计后的每个TRP的闭环功率调节值。
在一些实施例中，多个TRP的TPC命令承载在DCI(Downlink Control Information，下行控制信息)中，下面对终端如何根据TPC命令确定TRP进行说明。
在本申请实施例中，网络设备向终端发送的TPC命令承载在DCI中，则终端会根据DCI中的TPC命令确定TPC命令对应的TRP，进而确定每个TRP的闭环功率调节值。
可选地，TPC命令可以承载在一个DCI或多个DCI中，而对于终端来说，承载在一个DCI或多个DCI中确定TRP的方式也不同，下面对不同的方式进行说明。
第一种：至少两个TPC命令承载在一个DCI中。
在一些实施例中，在至少两个TPC命令承载在一个DCI中的情况下，DCI包括的TPC域的位置与TRP具有默认映射关系，TRP基于DCI包括的TPC域的位置以及默认映射关系确定。
在本申请实施例中，网络设备通过发送一个DCI为终端指示多个TRP的闭环功率调节值，则终端接收到该DCI后，即可根据该DCI确定TPC命令对应的TRP。
其中，该DCI中包括多个TPC域，而终端的默认映射关系包括TPC域与TRP的对应关系，因此终端可以根据TPC域的位置以及默认映射关系确定对应的TRP。
也就是说，终端接收到该DCI后，即可根据该DCI中包括的TPC域的位置以及默认映射关系，确定每个TPC域对应的TRP，进而终端可以基于确定的对应相同TRP的TPC命令指示的闭环功率调节值，确定每个TRP的闭环功率调节值。
例如，该DCI中的第N个TPC域对应第N个TRP，N为正整数。也即是说，若DCI中包括两个TPC域，则第一个TPC域对应第一个TRP，第二个TPC域对应第二个TRP。
可选地，TPC域与TRP的映射关系实际上通过TCI(Transmission Configuration Indication，传输配置指示)状态指示，该TCI状态与TRP具有对应关系。也就是说，该DCI中包括的TPC域的位置通过对应的TCI状态来指示对应的TRP。
例如，第N个TPC域对应第N个TCI状态，该第N个TCI状态对应第N个TRP，也就是说第N个TPC域对应第N个TRP。
在另一些实施例中，在至少两个TPC命令承载在一个DCI中的情况下，DCI包括映射标识，映射标识用于指示TPC域的位置与TRP的映射关系，TRP基于DCI包括的TPC域的位置以及指示标识指示的映射关系确定。
在本申请实施例中，网络设备通过发送一个DCI为终端指示多个TRP的闭环功率调节值，则终端接收到该DCI后，即可根据该DCI确定TPC命令对应的TRP。
其中，该DCI中包括映射标识，该映射标识用于指示TPC域的位置与TRP的映射关系，也就是说，通过该映射标识来告知终端TPC域的位置与TRP的映 射关系，进而终端可以根据TPC域的位置确定对应的TRP。
在一些实施例中，该映射标识指示顺序映射，该顺序映射是指第N个TPC域对应第N个TRP，N为正整数。也即是说，若DCI中包括两个TPC域，则第一个TPC域对应第一个TRP，第二个TPC域对应第二个TRP。
可选地，TPC域与TRP的映射关系实际上通过TCI状态指示，该TCI状态与TRP具有对应关系。也就是说，该DCI中包括的TPC域的位置通过对应的TCI状态来指示对应的TRP。
例如，第N个TPC域对应第N个TCI状态，该TCI状态对应TRP，也就是说第N个TPC域对应第N个TRP。
在一些实施例中，该映射标识指示交叉映射，该交叉映射是指第一个TPC域对应第二个TRP，而第二个TPC域对应第一个TRP。
可选地，TPC域与TRP的映射关系实际上通过TCI状态指示，该TCI状态与TRP具有对应关系。也就是说，该DCI中包括的TPC域的位置通过对应的TCI状态来指示对应的TRP。
例如，第1个TPC域对应第2个TCI状态，该第2个TCI状态对应第2个TRP，第2个TPC域对应第1个TCI状态，该第1个TCI状态对应第1个TRP。
第二种：在多个TPC命令承载在多个DCI中的情况下，TRP基于每个DCI包括的指示标识确定，既一个TPC命令承载在一个DCI中。
在本申请实施例中，该指示标识指示TRP，也就是说每个TPC命令对应一个TRP，终端根据每个DCI中包括的指示标识来确定该DCI对应的TRP。
可选地，该指示标识为CORESETPoolIndex(资源集池标识)，或者为其他标识，本申请实施例不作限定。
本申请实施例提供的方案中，通过TPC命令承载在DCI中，终端根据DCI中包括的TPC域即可确定对应的TRP，进而终端可以确定每个TRP对应的闭环功率调节值，保证了确定的闭环功率调节值的准确性，进而提高了传输的可靠性。
在一些实施例中，终端还可以根据TPC命令关联的闭环功率索引进行闭环功率调节值累计。
其中，不同TRP的TPC命令关联的闭环功率索引不同。也就是说，每个TRP的TPC命令关联一个相同的闭环功率索引，终端可以根据TPC命令关联的闭环功率索引确定是否为同一个TRP，在TPC命令关联的闭环功率索引相同的 情况下，确定TPC命令对应相同的TRP。
可选地，网络设备可以为终端的TPC命令配置闭环功率索引。图5示出了本申请一个示例性实施例提供的闭环功率索引配置方法的流程图，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501：网络设备向终端发送第一配置信令，该第一配置信令用于为不同的TRP的TPC命令配置不同的闭环功率索引。
步骤502：终端接收第一配置信令。
在本申请实施例中，网络设备可以通过第一配置信令来配置不同的TRP的TPC命令的闭环功率索引，则终端在接收到网络设备发送的第一配置信令后，即可确定每个TRP的TPC命令的闭环功率索引，进而若终端需要确定每个TRP的闭环功率调节值时，根据闭环功率索引即可确定对应的TRP，进而确定每个TRP的闭环功率调节值。
在一些实施例中，第一配置信令用于配置闭环功率索引与TCI状态关联关系。
在本申请实施例中，闭环功率索引与TCI状态具有关联关系，则TCI状态的源参考信号为不同TRP的CSI-RS(Channel State Information Reference Signal，信道状态信息参考信号)或者SSB(Synchronization Signal Block,同步信号块)时，该TCI状态关联的闭环功率索引也不同。又或者，TCI状态的源参考信号为探测参考信号，且如果探测参考信号为不同panel(天线面板)的探测参考信号时，该TCI状态关联的闭环功率索引也不同。
在另一些实施例中，第一配置信令用于为不同TRP配置不同的开环功率控制参数集，不同的开环功率控制参数集包括不同的闭环功率索引。
在本申请实施例中，闭环功率索引与TCI状态不具有关联关系，则在此情况下，为不同TRP配置不同的开环功率控制参数集，不同的开环功率控制参数集包括不同的闭环功率索引，因此根据闭环功率控制参数集即可确定不同的闭环功率索引。
在另一些实施例中，TPC命令包括闭环功率索引。也就是说，TPC命令和闭环功率索引均携带在同一信令中来指示TRP的闭环功率调节值，由于该闭环功率索引与TPC命令对应，因此终端也可以确定TPC命令对应的TRP。
本申请实施例提供的方案中，通过不同的关联方式均可确定TPC命令对应 的TRP，进而终端可以确定每个TRP的闭环功率控制参数，确定每个TRP的发射功率，保证了确定的闭环功率调节值的准确性，进而保证了传输的可靠性。
图3所示实施例对终端可以确定闭环功率调节值进行说明。而在另一实施例中，终端还会对闭环功率调节值进行重置。图6示出了本申请一个示例性实施例提供的闭环功率调节值重置方法的流程图，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601：网络设备向终端发送第二配置信令，该第二配置信令用于重配开环功率参数，该第二配置信令用于终端对闭环功率调节值进行重置。
步骤602：终端接收网络设备发送的第二配置信令。
在本申请实施例中，网络设备通过第二配置信令为终端重新配置开环功率参数，在此情况下，终端还会根据该第二配置信令，重置闭环功率调节值。
其中，该开环功率参数包括P 0、α、PL中的至少一项，P 0为目标接收功率，该目标接收功率为网络设备配置的期望接收功率，α为部分路径补偿因子，PL为路径损耗。
在一些实施例中，终端通过默认方式对闭环功率调节值进行重置。
可选地，第二配置信令用于终端对每个TRP对应的闭环功率调节值进行重置。
在本申请实施例中，该第二配置信息不指示TRP，在此情况下，终端就会对每个TRP对应的闭环功率调节值进行重置。
可选地，第二配置信令用于终端对第二配置信令指示的TRP对应的闭环功率调节值进行重置。
在本申请实施例中，该第二配置信令可以指示TRP，则对于终端来说，终端可以对该第二配置信令指示的TRP的闭环功率调节值进行重置，而对于其他TRP来说，无需重置其他TRP的闭环功率调节值。
在另一些实施例中，第二配置信令还包括指示信息，指示信息用于指示是否对闭环功率调节值进行重置，终端通过第二配置信令中的指示信息确定是否对闭环功率调节值进行重置。
可选地，在指示信息指示对闭环功率调节值进行重置的情况下，第二配置信令用于终端对每个TRP对应的闭环功率调节值进行重置。
在本申请实施例中，该第二配置信息不指示TRP，若指示信息指示需要对 闭环功率调节值进行重置，则在此情况下，终端就会对每个TRP对应的闭环功率调节值进行重置。
可选地，在指示信息指示对闭环功率调节值进行重置的情况下，第二配置信令用于终端对第二配置信令指示的TRP对应的闭环功率调节值进行重置。
在本申请实施例中，该第二配置信令可以指示TRP，则对于终端来说，若指示信息指示对闭环功率调节值进行重置，则终端可以对该第二配置信令指示的TRP的闭环功率调节值进行重置，而对于其他TRP来说，无需重置其他TRP的闭环功率调节值。
本申请实施例提供的方案中，终端基于网络设备配置的开环功率参数，确定是否对TPR的闭环功率调节值进行重置，提高了闭环功率调节值进行重置的准确性。
需要说明的是，上述实施例可以拆分为新实施例，或与其他实施例互相组合为新实施例，本申请对实施例之间的组合不做限定。
图7示出了本申请一个示例性实施例提供的闭环功率调节值确定方法的流程图，示例性的可以应用于如图1所示的终端中，该方法包括以下内容中的至少部分内容：
步骤701：终端接收网络设备发送的TPC命令，TPC命令用于为终端配置多个TRP的闭环功率调节值，每个TRP对应的TPC命令对应的闭环功率调节值用于确定终端到TRP对应的上行发射功率。
在本申请实施例中，终端可以通过网络设备配置的TRP进行上行数据传输。而对于终端来说，终端可以在同一时刻向网络设备传输上行数据，则对于终端来说，终端需要确定每个TRP对应的闭环功率调节值，进而基于确定的每个TRP对应的上行发射功率进行上行数据传输。
在一些实施例中，该闭环功率调节值确定上行发射功率的方式请参见上述实施例中的确定传输功率的方式。
网络设备可以通过TPC命令为终端配置多个TRP的闭环功率调节值，则终端在接收该TPC命令后，即可确定每个TRP的闭环功率调节值，进而基于每个TRP对应的TPC命令对应的闭环功率调节值确定终端到TRP对应的上行发射功率，以便于终端基于每个TRP对应的上行发射功率向网络设备发送上行数据。
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可以单独形成一个新的实施例，本申请实施例不作限定。
本申请实施例提供的方案中，终端根据TPC命令即可确定每个TRP对应的闭环功率调节值，进而终端基于每个TRP对应的闭环功率调节值以及终端到各个TRP的实际情况，进行动态发射功率调节，以便于在保证减小干扰前提下，保证终端以较大的发送功率进行上行传输，以保证系统吞吐量。
图7所示实施例对终端需要确定每个TRP的闭环功率调节值进行说明。下面，对终端具体如何根据TPC命令确定每个TRP的闭环功率调节值进行说明。
在一些实施例中，每个TRP的闭环功率调节值有TRP对应的TPC命令指示的闭环功率调节值累计得到。
在本申请实施例中，终端需要确定每个TRP的闭环功率调节值，而每个TRP的闭环功率调节值由该终端在多个时刻对应的闭环功率调节值进行累计得到。也就是说，终端需要对每个TRP对应的TPC命令指示的闭环功率调节值进行累计，得到当前时刻每个TRP的闭环功率调节值。
可选地，f(i，l，t)＝f(i-i 0，l，t)+Σδ，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。
例如，如图4所示，终端会对Δt内所有属于同一closed loop processes的TPC命令指示的闭环功率调节值进行累计，以得到累计后的每个TRP的闭环功率调节值。
在一些实施例中，多个TRP的TPC命令承载在DCI中，下面对终端如何根据TPC命令确定TRP进行说明。
在本申请实施例中，网络设备向终端发送的TPC命令承载在DCI中，则终端会根据DCI中的TPC命令确定TPC命令对应的TRP，进而确定每个TRP的闭环功率调节值。
可选地，TPC命令可以承载在一个DCI或多个DCI中，而对于终端来说，承载在一个DCI或多个DCI中确定TRP的方式也不同，下面对不同的方式进行说明。
第一种：至少两个TPC命令承载在一个DCI中。
在一些实施例中，在至少两个TPC命令承载在一个DCI中的情况下，DCI包括的TPC域的位置与TRP具有默认映射关系，TRP基于DCI包括的TPC域 的位置以及默认映射关系确定。
在本申请实施例中，网络设备通过发送一个DCI为终端指示多个TRP的闭环功率调节值，则终端接收到该DCI后，即可根据该DCI确定TPC命令对应的TRP。
其中，该DCI中包括多个TPC域，而终端的默认映射关系包括TPC域与TRP的对应关系，因此终端可以根据TPC域的位置以及默认映射关系确定对应的TRP。

图8所示实施例对终端需要确定每个TRP的闭环功率调节值进行说明。下面，对终端具体如何根据TPC命令确定每个TRP的闭环功率调节值进行说明。
在一些实施例中，每个TRP的闭环功率调节值有TRP对应的TPC命令指示的闭环功率调节值累计得到。
在本申请实施例中，终端需要确定每个TRP的闭环功率调节值，而每个TRP的闭环功率调节值由该终端在多个时刻对应的闭环功率调节值进行累计得到。也就是说，终端需要对每个TRP对应的TPC命令指示的闭环功率调节值进行累计，得到当前时刻每个TRP的闭环功率调节值。

在另一些实施例中，第一配置信令用于为不同TRP配置不同的开环功率控制参数集，不同的开环功率控制参数集包括不同的闭环功率索引。

在另一些实施例中，TPC命令包括闭环功率索引。也就是说，TPC命令和闭环功率索引均携带在同一信令中来指示TRP的闭环功率调节值，由于该闭环功率索引与TPC命令对应，因此终端也可以确定TPC命令对应的TRP。
