具体实施方式
下文中将结合附图对本申请的实施例进行详细说明。
波束是高频段通信提高传输距离，避免干扰的有效手段。波束具有方向性和宽度，为了覆盖不同方向，通常发送端和接收端会配置多天线，形成多个方向的波束。
无线通信节点的多天线可以分为不同组，每组称为antenna panel，也叫天线面板，简称为panel。UE一般可以支持多个antenna panel，分别覆盖不同方向。不同的antenna panel一般可以同时发送波束。每个antenna panel上可以同时发送一个到多个波束。每个antenna panel上可以同时发送的波束数量比该antenna panel可以支持的最大波束数量少。
基站也可以支持多个antenna panel，但是基站的antenna panel信息对UE是透明的。图1为一实施例提供的基站与配置多天线UE进行通信的波束示意图。图1中所示基站11的3个波束中的1个波束12与UE 13的两个天线面板14、天线面板15通信，天线面板14、天线面板15各有1个波束与基站的波束通信。
对多波束的功率控制机制是由基站为UE配置上行传输的功率控制参数，采用如下方式配置：
1)基站为UE配置J套开环功率控制参数，每套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为大于或等于1的整数；每套开环功率控制参数用j标识，j为整数，并且0<＝j<J。
2)基站为UE配置K套路损测量参数，每套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。其中，K为大于或等于1的整数；每套路损测量参数用k标识，k为整数，并且0<＝k<K。路损测量参数也写作PL-RS参数，是用于估计路径损耗(pathloss)的参考信号(Reference Signal，RS)的指示，包括以下至少之一，CRI-RS指示，同步信号块(Synchronization Signal Block，SSB)指示。 SSB也可以表示由物理广播信道(Physical Broadcast Channel，PBCH)的主同步信号(Primary Synchronization Signal，PSS)、从同步信号(Secondary Synchronization Signal，SSS)、解调参考信号(Demodulation reference signals，DM-RS，DM-RS)组成的同步信号/物理广播信道块(Synchronization Signal/Physical Broadcast Channel，SS/PBCH Block)。
3)基站为UE配置L套闭环功率控制参数，每套闭环功率控制参数包括以下至少之一：闭环功率控制标识，闭环功率控制数量。其中，L为大于或等于1的整数。每套闭环功率控制参数用l标识，l为整数，并且0<＝l<L。
UE的上行传输包括以下至少之一：物理上行共享信道(Physical Uplink Shared Channel，PUSCH)传输、物理上行控制信道(Physical Uplink Control Channel，PUCCH)传输。基站为UE配置至少一个探测参考信号(Sounding Reference Signal，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、空域等参数。
基站配置PUSCH的至少一个SRS资源指示(SRS Resource Indicator，SRI)值与功率控制参数的关联关系。例如，SRI＝0时，j＝0，k＝1，l＝0；SRI＝1时，j＝1，k＝1，l＝0。其中，每个SRI的取值表示至少一个SRS资源。基站用下行控制信息(Downlink Control Information，DCI)调度PUSCH传输时，使用SRI域描述PUSCH的空域参数，例如，空间关系信息，SRS端口(port)等。指示多个波束(beam)的SRI称为复合beam SRI；指示单个beam的SRI称为单个beam SRI。
PUSCH传输可以被DCI中包含的上行授权信息(UL grant)动态调度，也可以被半静态调度。动态调度称为基于动态授权的传输(grant based transmission)；半静态调度称为无需动态授权的传输(grant free transmission)，也叫配置授权(configured grant)的传输。配置授权的传输又分为两类：对于类型1的传输，所有授权信息都是高层信令配置的；对于类型2的传输，高层信令配置一部分授权信息，还有一部分授权信息是通过物理层控制信令DCI发送的，物理层控制信令对若干个传输有效。
对一个基于动态授权的PUSCH传输，通过调度该传输的DCI中的SRI域查表SRI值与功率控制参数的关联关系即可获得PUSCH传输的功控参数。对一个配置授权的PUSCH传输，通过高层信令配置开环功控参数和闭环功控参数。类型1的配置授权的PUSCH传输的路损测量参数通过高层信令配置。类型2的配置授权的PUSCH传输的路损测量参数通过激活当前PUSCH传输的DCI中的SRI域查表SRI值与功率控制参数的关联关系即可获得。
基站配置PUCCH的至少一个空间关系，并配置空间关系与功率控制参数的关联关系。例如，为空间关系1配置j＝0，k＝1，l＝0；为空间关系2配置j＝1， k＝1，l＝0。基站通过介质访问控制层控制元素(Media Access Control Address Control Element，MAC CE)激活PUCCH资源对应的空间关系。PUCCH的传输被DCI触发，DCI中指示PUCCH传输使用的PUCCH资源。结合以上两者，UE可以获得PUCCH传输的空间关系，使用空间关系查询空间关系与功率控制参数的关联关系即可获得该PUCCH传输的功控参数。空间关系可以用上行参考信号，和/或下行参考信号指示。参考信号指示为参考信号资源指示。而参考信号包括以下至少之一：SRS，信道状态信息参考信号(Channel Status Information-Reference Signal，CSI-RS)，SSB。闭环功控参数是指闭环功率控制数量，例如闭环功率控制数量为2，则支持l＝0和l＝1两个闭环功控进程，或者叫闭环功控环，或者简称闭环功控。
每个上行传输都有确定的一个闭环功控标识。基站根据历史的上行传输的测量结果与目标的差距确定需要UE调整的功率偏差，以传输功控命令(Transmit Power Control Command，TPC Command)(即DCI中针对PUSCH的δ PUSCH和针对PUCCH的δ PUCCH)的方式通知UE。UE为每个闭环功控标识维护一个本地的功率调整量f(l)，根据TPC命令进行更新，达到闭环控制功率的目的。
移动通信网络中，支持UE侧的多个波束同时发送，如图1所示，UE包含两个panel，两个分别来自不同panel的波束与基站的一个波束进行通信。UE的两个同时发送的波束用DCI中的SRI域的一个值描述，并对应一套功控参数。即，基站为同时发送的多个波束配置一个PL-RS。UE测量PL-RS，同时传输的多个beam都可以测量PL-RS，可以得到多个路损测量结果。由UE的实现来决定如何从多个路损得到一个路损。UE为同时发送的多个beam计算一个发送功率值，按照beam或者port均分功率。
在新一代的移动通信网络中，基站侧要实现多TRP的配置，每个TRP可以包括至少一个antenna panel，在实际部署中，基站的多个TRP的地理位置可能相距较远，那么对于基站的多TRP场景，每个TRP面临的信道环境是不同的。如图2所示，图2为一实施例提供的基站多TRP场景下与UE进行通信的波束示意图。当基站21配置两个TRP 22、TRP 23时，不同的TRP分别与UE 24的两个天线面板25、天线面板26通信。由于TRP22和TRP23在不同的地点，因此会受到不同的干扰，对各自的链路会有不同的发送功率要求。对于基站发送的下行信号而言，所有的功率控制方式都由基站自己进行控制，但对于UE发送的上行信号，各种资源的调度都是由基站发送的下行控制信息所指示的。在基站支持多TRP的场景下，基站对UE与不同的TRP进行通信所使用的波束的发送功率也可能有不同的要求。
对于PUSCH传输，对于多TRP场景，TRP对应的PUSCH传输应该独立进 行功控。假设当前功控机制支持多TRP，则与PUSCH传输关联的SRI只有一套编号，SRI编号与TRP的对应关系是基站知道的，基站由此配置SRI与功控参数的映射(mapping)关系。即，SRI、功控参数都不显式与TRP关联。例如，PUSCH传输关联的SRI只有一套编号，即，与PUSCH传输对应的SRS资源集合(resource set)只有一个。当PUSCH传输是基于码本的传输(Codebook Based PUSCH transmission，CB)时，可以确定一个CB对应的SRS resource set；当PUSCH传输是基于非码本的传输(Non-Codebook Based PUSCH transmission)时，可以确定一个NCB对应的SRS resource set。但当前的实现方式存在以下问题：开环功控参数、闭环功控参数、路损测量参数的配置数量有限，尤其是闭环(closed loop)数量最大只有2。如果支持2个TRP，每个TRP只能配置1个closed loop，则每个TRP不能支持两个闭环，那么grant based PUSCH、grant free PUSCH独立配置闭环功控就不能实现，并行的两个波束对(beam pair link)独立配置闭环功控也不能实现。
对于PUCCH传输，对于多TRP场景，TRP对应的PUCCH传输应该独立进行功控。假设当前功控机制支持多TRP，则与PUCCH传输关联的空间关系只有一套编号，空间关系编号与TRP的对应关系是基站知道的，基站由此配置空间关系与功控参数的映射关系。即，空间关系、功控参数都不显式与TRP关联。例如，PUCCH传输关联的空间关系只有一套编号，包括，与PUCCH传输对应PUCCH resource set可能多于一个，但是对于一个PUCCH传输，根据其负载(payload)大小可以确定一个PUCCH resource set。PUCCH resource set中包含至少一个PUCCH资源(resource)。高层参数还配置PUCCH resource可能的空间关系与功控参数的关联关系。根据触发PUCCH传输的DCI获取PUCCH资源指示(resource indicator)，根据介质访问控制(Media Access Control Address，MAC)层参数激活的PUCCH resource的空间关系，在PUCCH resource的空间关系中获得功控参数。但当前的实现方式存在以下问题：开环功控参数、闭环功控参数、路损测量参数的配置数量有限，尤其是closed loop数量最大只有2。如果支持2个TRP，每个TRP只能配置1个closed loop，则每个TRP不能支持两个闭环，那么就不能实现一个TRP上两个波束对链路(beam pair link)独立配置PUCCH的闭环功控。
综上，对于多TRP场景下，UE的上行传输功率控制存在很多限制。
图3为一实施例提供的一种功率控制方法的流程图，如图3所示，本实施例提供的方法包括如下步骤。
步骤S3010，获取至少一个空域资源信息与功率控制参数的关联。
本实施例提供的功率控制方法应用于无线通信系统中的用户侧终端设备， 简称UE。UE在无线通信系统中使用上行信道进行上行传输。在UE进行上行传输时，首先需要请求网络侧的基站设备分配传输资源，当基站为UE分配了传输资源后，分配的传输资源在传输空间中占用的空域资源信息也是确定的。因此，为了实现对UE上行传输的功率控制，就可以为空域资源信息关联功率控制参数。UE上行传输所占用的空间资源可以从多个维度描述，对应于UE所进行的相同或不同的上行传输，而当UE所使用的空间资源确定，对应的功率控制参数就应该被确定。因此一个功率控制参数可以与一个或多个空域资源信息关联。至少一个空域资源信息与功率控制参数的关联是预先配置的，或者由基站配置的。通过确定的一个或多个空域资源信息，可以确定关联的功率控制参数。至少一个空域资源信息与功率控制参数的关联可以是每个空域资源信息均与功率控制参数关联，也可以是一个或多个空域资源信息与功率控制参数直接关联，其他空域资源信息与已关联的空域资源信息所关联，也就是与功率控制参数间接关联。
其中，空域资源信息包括控制资源集合(Control Resource Set，CORESET)信息、TRP信息、PUCCH资源信息中的至少一类。其中，CORESET指示频域、时域资源的分配，基站为UE分配至少一个CORESET。TRP信息表示基站在多TRP场景下所使用的TRP的标识信息。PUCCH资源信息用于指示UE传输PUCCH所使用的传输资源。UE获取上述几类空域资源信息中一类或多类空域资源信息与功率控制参数的关联。
空域资源信息还包括空间关系信息、参考信号信息中的至少一类。
空间关系信息用于PUCCH的传输。参考信号信息包括参考信号的配置信息。
若UE获取的至少一个空域资源信息与功率控制参数的关联中的空域资源信息包括CORESET信息、TRP信息、PUCCH资源信息、空间关系信息、参考信号信息中的至少两类信息，则至少两类信息具有关联关系。由于至少一个空域资源信息与功率控制参数的关联可能仅是一类空域资源信息与功率控制参数的关联，因此UE在获取到至少一个空域资源信息中的任一个空域资源信息后，可以根据获取的至少两类空域资源信息的关联关系，直接或间接地确定上行传输的功率控制参数。
例如，空域资源信息包括CORESET信息、参考信号信息，基站可以为UE配置参考信号信息与功率控制参数的关联。如基站为UE的PUSCH传输配置至少一个SRI与功率控制参数的关联，而SRI与CORESET信息有关联关系。那么一个上行传输相关的DCI所属的CORESET可以用于确定SRI的含义。如，一个SRS resource set中包括2个SRS resource，每个分别与一个CORESET关联， 那么在第一个CORESET上检测到的DCI调度的PUSCH对应第一个SRS resource；在第二个CORESET上检测到的DCI调度的PUSCH对应第二个SRS resource。
进而，不同的CORESET对应不同的SRI与功率控制参数的关联关系。UE根据上行传输相关的DCI所属的CORESET决定使用该CORESET对应的SRI与功率控制参数的关联关系。
或者，SRS resource set与CORESET信息有关联关系。一个SRS resource set中包括至少一个SRS resource。在第一个CORESET上检测到的DCI调度的PUSCH对应第一个SRS resource set；在第二个CORESET上检测到的DCI调度的PUSCH对应第二个SRS resource set。DCI中包括的SRI域与该DCI所属CORESET关联的SRS resource set中包含的SRS resource有对应关系。
进而，不同的CORESET对应不同的SRI与功率控制参数的关联关系。UE根据上行传输相关的DCI所属的CORESET决定使用该CORESET对应的SRI与功率控制参数的关联关系。
CORESET信息包括以下之一：CORESET、CORESET组、CORESET索引、CORESET组索引；TRP信息包括以下之一：TRP、TRP组、TRP索引、TRP组索引；PUCCH资源信息包括以下之一：PUCCH资源、PUCCH资源组、PUCCH资源索引、PUCCH资源组索引；空间关系信息包括至少一个参考信号信息；参考信号信息包括以下之一：参考信号、参考信号资源、参考信号资源集合、参考信号资源分组、参考信号索引、参考信号资源索引、参考信号资源集合索引、参考信号资源分组索引。
上述索引(index)，也称为编号、指示或标识(identification、indicator或indication)。参考信号可以是上行参考信号，或下行参考信号。上行参考信号包括以下之一：SRS、解调参考信号(Demodulation Reference Signal，DMRS)、相位跟踪参考信号(Phase Tracking Reference Signal，PTRS)，追踪参考信号(Tracking Reference Signal，TRS)。下行参考信号包括以下之一：CSI-RS、SSB、DMRS、PTRS、TRS。
参考信号资源集合(RS resource set)中包括至少一个参考信号资源。例如，SRS resource set中包括至少一个SRS resource。参考信号资源分组(RS resource group)中包括至少一个参考信号资源的组合，每一个参考信号资源的组合中包含至少一个参考信号资源。例如，4个SRS resources最多有15种不同组合，用不同的SRI(SRS Resource Indicator)指示。
例如，基站为UE的传输方式为基于非码本的(non codebook based)传输 配置了SRS资源集合，其中包括4个SRS资源，分别为SRS1到SRS4。在DCI中使用SRI信息指示使用的SRS资源时，最多有15种组合方式，分别为：
SRI0:SRS1；SRI1:SRS2；SRI2:SRS3；SRI3:SRS4；SRI4:SRS1SRS2；SRI5:SRS1SRS3；SRI6:SRS1SRS4；SRI7:SRS2SRS3；SRI8:SRS2SRS4；SRI9:SRS3SRS4；SRI10:SRS1SRS2SRS3；SRI11:SRS1SRS2SRS4；SRI12:SRS1SRS3SRS4；SRI13:SRS2SRS3SRS4；SRI14:SRS1SRS2SRS3SRS4。
空域资源信息与功率控制参数的关联可以包括空域资源信息的所有类信息以及功率控制参数的关联。或者，空域资源信息中的一类空域资源信息对应至少一个包括其他类空域资源信息与功率控制参数的关联。
例如，一个空域资源信息与功率控制参数的关联中的空域资源信息包含CORESET信息和参考信号信息(如SRI或空间关系)，则一个空域资源信息与功率控制参数的关联中包括：CORESET信息、SRI(或空间关系)和功率控制参数。或，每一个SRI与功率控制参数的关联都与一个CORESET信息绑定或关联。具体实施方式为在每一个SRI(或空间关系)与功率控制参数的关联中包含一个CORESET信息，或为每一个CORESET信息配置至少一个SRI(或空间关系)与功率控制参数的关联。
再例如，一个空域资源信息与功率控制参数的关联中的空域资源信息包含TRP信息和参考信号信息(如SRI或空间关系)，则一个空域资源信息与功率控制参数的关联中包括：TRP信息、SRI(或空间关系)和功率控制参数。或，每一个SRI(或空间关系)与功率控制参数的关联都与一个TRP信息绑定或关联。具体实施方式为在每一个SRI(或空间关系)与功率控制参数的关联中包含一个TRP信息，或为每一个TRP信息配置至少一个SRI(或空间关系)与功率控制参数的关联。
功率控制参数包括开环功控参数、闭环功控参数、路损测量参数中的至少一种。开环功率控制参数包括以下至少之一：开环功率控制参数标识、目标接收功率、路损因子；路损测量参数包括以下至少之一：路损测量参数标识、用于路损测量的参考信号资源类型指示、用于路损测量的参考信号资源指示；闭环功率控制参数包括以下至少之一：闭环功率控制进程标识、闭环功率控制进程个数。
获取至少一个空域资源信息与功率控制参数的关联，包括：
根据以下信息之一，获取至少一个空域资源信息与功率控制参数的关联：
功率控制参数或功率控制相关参数，其中包括功率控制参数所关联的空域资源信息；空域资源信息或空域资源信息相关参数，其中包括空域资源信息所 关联的功率控制参数；功率控制相关参数，其中包括至少一套功率控制参数，每套功率控制参数与空域资源信息关联；预定义的空域资源信息与功率控制参数的关联；配置的空域资源信息与功率控制参数的关联；其中，功率控制相关参数中包括功率控制参数，空域资源信息相关参数中包括空域资源信息参数。
例如，设空域资源信息包括CORESET信息。基站为UE配置了两套功率控制参数PowerControlParas0和PowerControlParas1(用PowerControlParas-Id标识)，分别与CORESET_Config0和CORESET_Config1(用GroupId标识)关联。
根据以下之一的信息，获取空域资源信息CORESET信息与功率控制参数的关联：
1)功率控制参数或功率控制相关参数，其中包括功率控制参数所关联的空域资源信息。
功率控制参数包括功率控制参数所关联的空域资源信息举例：PowerControlParas参数中增加CORESET信息。功率控制参数PowerControlParas:{GroupId,...}。具体地，基站配置以下功率控制参数给UE，如PowerControlParas0:{group0,...}，PowerControlParas1:{group1,...}。
功率控制相关参数包括功率控制参数所关联的空域资源信息。功率控制相关参数，如config中包括功率控制参数。功率控制相关参数可以理解为包含功率控制参数的上一层或多层信令结构体。
如果功率控制相关参数中包括了功率控制参数所关联的空域资源信息GroupId，则功率控制相关参数包括至少一个功率控制参数。
UE获取上述信息，可以获得功率控制参数PowerControlParas与CORESET信息的关联。
功率控制参数是以下之一的高层参数：PUSCH-PowerControl、pucch-PowerControl，BWP-UplinkDedicated；功率控制相关参数可以是以下之一的高层参数：PUSCH-Config、PUCCH-Config。
如功率控制参数PUSCH-PowerControl中包含CORESET信息GroupId，将其按照ASN.1格式写为：
Figure PCTCN2020080671-appb-000001
Figure PCTCN2020080671-appb-000002
功率控制相关参数是包含功率控制参数PUSCH-PowerControl的信令结构体，假设为PUSCH-Config，其中包含至少一个功率控制参数PUSCH-PowerControl，有两种方式。方式1，PUSCH-Config支持一次配置多个功率控制参数PUSCH-PowerControl，如下所示：
Figure PCTCN2020080671-appb-000003
方式2，PUSCH-Config以addmode-release的方式支持多个功率控制参数PUSCH-PowerControl，如下所示：
Figure PCTCN2020080671-appb-000004
基站为UE配置至少一个pusch-PowerControl，每个pusch-PowerControl用pusch-PowerControl-Id标识。最大支持的数量为maxNrofpusch-PowerControl。
对PUCCH也有类似的实现方式，将上面结构体中的PUSCH替换为PUCCH即可，不再赘述。除了上述方式外，功率控制参数可以不带GroupId，而GroupId在功率控制相关参数中携带，那么在携带GroupId的功率控制相关参数的上一层或多层信令结构体中会包含至少一个携带GroupId的功率控制相关参数。包含至少一个携带GroupId的功率控制相关参数的方式可以是：支持一次配置多个功率控制相关参数，或以addmode-release的方式支持多个功率控制相关参数。
如果功率控制相关参数中没有包括功率控制参数所关联的空域资源信息 GroupId，则功率控制相关参数包括至少一个功率控制参数，并为每个功率控制参数关联空域资源信息GroupId。其中，为每个功率控制参数关联空域资源信息GroupId可能是以下方式之一：
A、每个功率控制相关参数包括一个空域资源信息GroupId和对应的功率控制参数；
举例：config：{PowerControlParas,GroupId,...}。
具体地，基站配置以下功率控制相关参数给UE，如
config0：{
PowerControlParas0,
group0,
...
}；
config1：{
PowerControlParas1,
group1,
...
}。
B、功率控制相关参数包括至少一个空域资源信息GroupId及其对应的功率控制参数；
具体地，基站配置以下功率控制相关参数给UE，如
Figure PCTCN2020080671-appb-000005
Figure PCTCN2020080671-appb-000006
C、功率控制相关参数包括至少一个功率控制参数，每个功率控制参数分别对应一个空域资源信息GroupId；即GroupId并不是直接携带的。
具体地，基站配置以下功率控制相关参数给UE，如
Figure PCTCN2020080671-appb-000007
比如，pusch-PowerControl可以不携带GroupId。
Figure PCTCN2020080671-appb-000008
又如，功率控制相关参数的上一层或多层信令结构体，BWP-UplinkDedicated中包括多个PUSCH-Config，分别对应不同的GroupId。那么PUSCH-Config及其下层的参数可以不包括GroupId。
Figure PCTCN2020080671-appb-000009
此处的举例只给了PUSCH传输相关的部分参数的情况，其他的传输例如PUCCH传输，也可以有类似的举例。如：
功率控制参数PUCCH-PowerControl包括GroupId。
Figure PCTCN2020080671-appb-000010
假设包含PUCCH-PowerControl的参数为PUCCH-Config，则基站可以为UE配置至少一个PUCCH-PowerControl以分别对应不同的TRP信息和/或CORESET信息。
另外，包含PUCCH-PowerControl的参数PUCCH-Config还可以是包括至少一个PUCCH-PowerControl，每个PUCCH-PowerControl对应一个TRP信息和/或CORESET信息，如下所示。其中spatialRelationInfo是PUCCH传输的空间关系。
Figure PCTCN2020080671-appb-000011
由于PUCCH-Config中包含PUCCH-PowerControl，还有可能是PUCCH-Config的上层参数之间为不同TRP信息和/或CORESET信息配置PUCCH-Config，如下所示：
Figure PCTCN2020080671-appb-000012
Figure PCTCN2020080671-appb-000013
2)空域资源信息或空域资源信息相关参数，其中包括空域资源信息所关联的功率控制参数；
举例：CORESET信息中包含PowerControlParas参数。CORESET_Config:{PowerControlParas-Id,...}。具体地，基站配置以下参数给UE，CORESET_Config0:{PowerControlParas0,...}，CORESET_Config1:{PowerControlParas1,...}。
空域资源信息相关参数可以理解为包含空域资源信息参数的上一层或多层信令结构体。举例：config：{CORESET_Config,Group-Id,...}。具体地，基站配置以下功率控制相关参数给UE，如config0：{CORESET_Config0,group0,...}；config1：{CORESET_Config1,group1,...}。例如，空域资源信息为空间关系时，对PUCCH传输，其空域资源信息参数假定为PUCCH-SpatialRelationInfo，空域资源信息参数中包括其对应的功率控制参数，如：
Figure PCTCN2020080671-appb-000014
另外，对于非TRP信息或CORESET信息的空域资源信息也可能与TRP信息和/或CORESET信息(用GroupId标识)建立关联。如下所示，PUCCH-SpatialRelationInfo需要包括GroupId：
Figure PCTCN2020080671-appb-000015
对PUSCH传输，空域资源信息可以是参考信号信息，如SRI,或SRS resource，或SRS resource set。
如：
Figure PCTCN2020080671-appb-000016
类似地，上面举例了空域资源信息可以包括GroupId。
空域资源信息也可以不包含GroupId，在其上层的参数，即包含空域资源信息参数的空域资源信息相关参数中指示空域资源信息参数与TRP信息和/或CORESET信息的关系。
3)功率控制相关参数，其中包括至少一套功率控制参数，每套功率控制参数与空域资源信息关联；
如功率控制参数PUSCH-PowerControl中不包含CORESET信息GroupId，将其按照ASN.1格式写为：
Figure PCTCN2020080671-appb-000017
功率控制相关参数是包含功率控制参数PUSCH-PowerControl的信令结构体，假设为PUSCH-Config，其中包含至少一个功率控制参数 PUSCH-PowerControl，如下所示：
Figure PCTCN2020080671-appb-000018
4)预定义的空域资源信息与功率控制参数的关联；
预定义的空域资源信息与功率控制参数的关联是指：基站为UE配置至少一套功率控制参数，并且配置功率控制参数的套数相同数量的CORESET信息，功率控制参数与CORESET信息按其编号顺序关联。PowerControlParas0关联group0，PowerControlParas1关联group1，以此类推。
如功率控制参数PUSCH-PowerControl中不包含CORESET信息GroupId，将其按照ASN.1格式写为：
Figure PCTCN2020080671-appb-000019
功率控制相关参数是包含功率控制参数PUSCH-PowerControl的信令结构体，假设为PUSCH-Config，其中包含至少一个功率控制参数PUSCH-PowerControl，如下所示：
Figure PCTCN2020080671-appb-000020
Figure PCTCN2020080671-appb-000021
多个pusch-PowerControl以预定义的方式对应CORESET信息的GroupId。
5)配置的空域资源信息与功率控制参数的关联。
配置的空域资源信息与功率控制参数的关联是指：基站为UE配置至少一套功率控制参数，并且配置至少一套CORESET信息，功率控制参数与CORESET信息的关联关系由基站配置。例如：Mapping：{Mapping-Id,PowerControlParas-Id,Group-ID}。进一步地，Mapping0：{PowerControlParas0,group1}表示PowerControlParas0关联group1，Mapping1：{PowerControlParas1,group0}表示PowerControlParas1关联group0等。
步骤S3020，获取上行传输的空域资源信息。
UE在无线通信系统中进行数据传输时使用上行信道进行上行传输，在UE需要进行不同类型的上行传输时，需要使用不同的空间资源。UE进行上行传输所使用的空间资源是由基站调度的，当UE确定所需进行的上行传输，就可以从基站获取对应的空域资源信息。
UE进行上行传输所使用的空域资源信息一般是由基站调度的，基站通过向UE发送DCI，DCI用于对UE的上行传输进行调度。由于DCI为一种控制信息，因此DCI是在CORESET确定的资源上发送的，那么UE在接收到DCI后，可以确定DCI所属的CORESET。接着UE就可以通过确定的CORESET获取空域资源信息中的CORESET信息。或者UE还可以根据接收的DCI所属的CORESET获取空间资源中的TRP信息，其中TRP信息与CORESET信息关联。再或者，UE还可以根据接收的DCI所属的CORESET同时获取空间资源中的CORESET信息和TRP信息。再或者，UE可以获取为上行传输配置的CORESET信息和/或TRP信息。
上行传输相关的DCI包括以下之一：调度上行传输的DCI、激活上行传输的DCI、上行传输所响应的DCI。
上行传输包括以下之一：PUSCH传输，PUCCH传输，SRS传输。也就是本实施例提供的功率控制方法可以对UE的各种上行传输进行独立、灵活的功率控制。
调度上行传输的DCI、激活上行传输的DCI、上行传输所响应的DCI。
例如，grant based PUSCH传输是由一个DCI调度的，DCI中包含该PUSCH传输的调度信息。其中调度信息也叫授权信息，grant信息。对于一个grant based PUSCH传输，其空域资源信息是通过调度该PUSCH传输的DCI所在的CORESET确定的。具体地，UE仅在基站配置的时频域位置检测DCI，这些时 频域位置通过CORESET以及搜索空间的方式配置给UE。因此，UE检测到DCI时，能确定该DCI对应的CORESET。由于CORESET与TRP绑定，或者说CORESET与TRP有关联关系，所以UE检测到DCI时，就能确定该DCI所调度的PUSCH传输的CORESET信息或TRP信息。
对于配置授权类型2的PUSCH传输，除了高层配置的参数外，还需要一个DCI激活。根据激活该PUSCH传输的DCI所属的CORESET就能确定该DCI所激活的PUSCH传输的CORESET信息或TRP信息。
对于PUCCH传输，传输相关的下行控制信息是指上行传输所响应的下行控制信息。PUCCH中包含了对下行传输的响应信息，调度该下行传输的DCI是该PUCCH传输相关的下行控制信息，或称为该PUCCH传输所响应的下行控制信息。根据该PUCCH传输所响应的下行控制信息所属的CORESET就能确定PUCCH传输的CORESET信息或TRP信息。
步骤S3030，根据上行传输的空域资源信息和至少一个空域资源信息与功率控制参数的关联确定上行传输的功率控制参数。
当UE确定了上行传输的空域资源信息，即可根据至少一个空域资源信息与功率控制参数的关联，确定上行传输所对应的功率控制参数。终端使用确定的功率控制参数对上行传输进行功率控制，即实现了对上行传输的功率控制。由于本实施例将功率控制参数与空域资源信息关联，当UE需要进行上行传输时，只要确定了上行传输所使用的空间资源，即可根据关联关系确定对应的功率控制参数，实现了对上行传输的功率控制。即使在基站多TRP场景下，由于基站使用不同TRP与UE通信所用的空间资源不同，那么UE也可以根据不同TRP所分别对应的空间资源，确定对应的功率控制参数，也就是实现了多TRP场景下的独立功率控制。
本实施例提供的功率控制方法，获取至少一个空域资源信息与功率控制参数的关联，然后在获取上行传输的空域资源信息时，即可根据上行传输的空域资源信息和至少一个空域资源信息与功率控制参数的关联确定上行传输的功率控制参数，由于UE在不同场景中进行上行传输所使用的空域资源信息不同，因此可以对UE的上行传输进行独立、灵活的功率控制。
图4为一实施例提供的另一种功率控制方法的流程图，如图4所示，本实施例提供的方法包括如下步骤。
步骤S4010，获取至少一个空域资源信息与功率控制参数的关联。
步骤S4020，获取上行传输的空域资源信息。
步骤S4030，根据上行传输的空域资源信息和至少一个空域资源信息与功率 控制参数的关联确定上行传输的功率控制参数。
步骤S4040，获取DCI中的TPC命令，TPC命令用于更新DCI所关联的闭环功控参数的功率控制调整状态。
UE的上行传输功率控制主要包括开环功率控制和闭环功率控制两种方式，以及使基站获知链路状态的路损测量参数。其中开环功率控制仅需根据空域资源信息与功率控制参数的关联获取一次开环功率控制参数即可。而闭环功率控制则需要基站根据UE上报的路损测量参数不断地向UE发送TPC命令，对UE的上行传输功率进行不断地调整。那么UE在接收到的DCI中就需要获取TPC命令。TPC命令根据历史的上行传输的测量结果与目标上行传输功率的差距确定UE需要调整的功率偏差。
UE根据接收到的DCI可以确定DCI所属CORESET，再根据CORESET可以直接或间接地确定关联的功率控制参数。那么UE可以使用获取到的TPC命令更新DCI关联的闭环功控参数的功率控制调整状态。这样就实现了对不同空域资源信息所对应的闭环功率控制参数进行独立的闭环更新。
DCI所关联的闭环功控参数采用如下方式确定：根据DCI所属的CORESET确定CORESET信息和/或TRP信息；根据确定的CORESET信息和/或TRP信息确定所述确定的CORESET信息和/或TRP信息所关联的功控参数中的闭环功控参数。DCI所属的CORESET即DCI信息所在的资源所属于的CORESET。
另外，在一实施例中，TPC命令与闭环功控参数的功率控制调整状态对应同一组上行传输的相同闭环功控参数。同一组上行传输与DCI所属的CORESET确定的CORESET信息和/或TRP信息有关联关系。
对一类上行传输，基站为UE配置至少一组上行传输，每组与一个CORESET信息和/或TRP信息关联。
上行传输包括以下至少之一的类型：PUSCH传输、配置授权的PUSCH传输、PUCCH传输、SRS传输。
例如，对PUSCH传输，包括至少一组PUSCH的配置信息，每组与一个CORESET信息和/或TRP信息关联。
对配置授权的PUSCH传输，包括至少一组配置授权PUSCH的配置信息，每组与一个CORESET信息和/或TRP信息关联。
对PUCCH传输，包括至少一组PUCCH的配置信息，每组与一个CORESET信息和/或TRP信息关联。或，对PUCCH传输，包括至少一组PUCCH资源的配置信息，每组与一个CORESET信息和/或TRP信息关联。
对SRS传输，包括至少一组SRS的配置信息，每组与一个CORESET信息和/或TRP信息关联。或，对SRS传输，包括至少一组SRS resource set的配置信息，每组与一个CORESET信息和/或TRP信息关联。或，对SRS传输，包括至少一组SRS resource的配置信息，每组与一个CORESET信息和/或TRP信息关联。
例如：DCI格式0_0和DCI格式0_1是用于调度PUSCH传输的，因此这些DCI包含的TPC命令用于更新PUSCH传输的闭环功控参数的功率控制调整状态。
DCI格式1_0和DCI格式1_1是用于调度PDSCH传输的，因此这些DCI包含的TPC命令用于更新PUCCH传输的闭环功控参数的功率控制调整状态。
DCI格式2_2是用于发送PUSCH传输或PUCCH传输的TPC命令，采用不同的循环冗余校验(Cyclic Redundancy Check，CRC)加扰方式区分。那么用TPC-PUSCH-RNTI加扰的DCI格式2_2包含的TPC命令用于更新PUSCH传输的闭环功控参数的功率控制调整状态；用TPC-PUCCH-RNTI加扰的DCI格式2_2包含的TPC命令用于更新PUCCH传输的闭环功控参数的功率控制调整状态。
DCI格式2_3是用于发送SRS传输的TPC命令，则DCI格式2_3包含的TPC命令用于更新SRS传输的闭环功控参数的功率控制调整状态。
对同一类上行传输可能会存在多于1个闭环功控编号，DCI中TPC命令只能用于其对应的闭环功控编号的功率控制调整状态。例如，DCI 0_1调度的PUSCH传输的闭环功控编号为0，则其中的TPC命令用于更新PUSCH传输的闭环功控编号为0的功率控制调整状态。
下面对于PUSCH传输，PUCCH传输，SRS传输三种不同的上行传输，对本申请实施例提供的功率控制方法进行详细说明。
首先，对于上行传输为PUSCH传输的情况：
在一实施例中，PUSCH传输关联的SRI只有一套编号，即PUSCH传输在确定基于码本传输或基于非码本传输后，只有一个对应的SRS resource set。SRS resource set包括至少一个SRS resource，每个SRS resource与一个TRP关联。这样做的好处在于：因为DCI可以确定所属的TRP，那么DCI中的SRI只需要指示所属的TRP所关联的SRI。DCI中的指示SRI域的开销可以减小。当DCI中的SRI只有一种可能时，SRI域可以不存在，即DCI与SRI的关联关系是预先确定的。或，DCI与SRI的关联关系是通过两者与TRP的关联关系间接获得的。
例如，SRS resource set for CB中包括2个SRS resources，每个SRS resource 对应一个TRP。假设SRS resource 0和SRS resource 1分别对应TRP 0和TRP 1，并且CORESET 0和CORESET 1分别对应TRP 0和TRP 1。那么通过CORESET0发送的DCI与TRP 0关联，进而，与SRS resource 0关联。由于DCI可以间接地关联到SRI上，因此对一个DCI，其关联的SRI只有一种可能，SRI域在DCI中可以不存在。
另外，对一个PUSCH传输，其相关的DCI所关联的SRI确定后，可以用以下方式之一确定该PUSCH传输的功控参数：
方式a：SRI与功控参数的关联关系是基站配置的；例如，无线资源控制(Radio Resource Control，RRC)信令配置SRI与功控参数的关联关系，即每个可能的SRI都对应确定的一组功控参数，包括以下至少之一：开环功控参数、闭环功控参数、路损测量参数。
方式b：配置功控参数与TRP的关联关系，SRI与功控参数的关联关系是通过TRP的关联关系间接获得。开环功控参数、闭环功控参数、路损测量参数的至少之一与TRP有预先配置或预先定义的关联关系。例如，TRP 0和TRP 1分别对应一套功控参数，其中功控参数包括以下至少之一：开环功控参数、闭环功控参数、路损测量参数。那么确定了SRI，并通过SRI所关联的TRP即可获得功控参数。
在另一实施例中，当基站采用多TRP传输的场景，需要UE的功率控制具有较强的灵活性，可以采用如下几种方式之一：
方式1：使用相关技术中的功控机制，扩充功控参数的上限数量。例如：开环功控参数、闭环功控参数、路损测量参数的至少之一的配置数量上限提升所支持的TRP的数量的倍数。例如，当支持TRP的数量为2时，将闭环功控数量上限从2提升2倍，即提高到4。这样闭环功控的编号0，1，2，3可以被配置给不同的TRP，实现不同TRP的独立功控。比如，TRP 0的闭环功控的编号为0和1，分别用于支持grant based和grant free的PUSCH传输的独立闭环功控，或分别用于支持两个beam pair link独立闭环功控。
方式2：不同TRP的闭环(closed loop)倾向于独立更新。在不扩充闭环功控参数上限数量的情况下，限制不同的TRP，即使closed loop的ID相同，也分别独立使用TPC命令。例如，闭环功控对于不同TRP独立维护。即DCI中承载的TPC命令只能用于更新DCI所关联的TRP对应的TPC命令。例如，当支持TRP的数量为2时，闭环功控数量上限为2。在TRP 0对应的CORESET 0中发送的DCI携带的TPC命令只能更新TRP 0所对应的闭环功控。在TRP 1对应的CORESET 1中发送的DCI携带的TPC命令只能更新TRP 1所对应的闭环功控。这样的好处是每个TRP都能支持独立的最大2个闭环功控。
方式3：为PUSCH码本或非码本传输配置多个SRS resource sets，每个SRS resource set分别对应1个TRP。由DCI所关联的TRP可以获得SRS resource set。SRS resource set中包括至少一个SRS resource。SRS resource(在DCI中用SRI指示)与功控参数的关联包括：基站为每个SRS resource set配置对应的一组SRI与功控参数的关联关系。
例如，针对每个SRS resource set，RRC信令配置一组SRI与功控参数的关联关系SRI-PUSCH-PowerControl。对每个SRS resource set，一组SRI-PUSCH-PowerControl可以包括多个，分别支持该SRS resource set中每个可能的SRI关联到一套功控参数。一套功控参数包括以下至少之一：开环功控参数、闭环功控参数、路损测量参数。如，第1组SRI-PUSCH-PowerControl对应CORESET 0调度的PUSCH传输；第2组SRI-PUSCH-PowerControl对应CORESET 1调度的PUSCH传输。
针对不同的SRS resource set，RRC信令配置SRI与功控参数的关联关系时，功控参数池的配置是区分TRP的。即针对不同的SRS resource set分别配置功控参数池。例如，对SRS resource set 0，功控参数池包括：2个开环功控参数，2个路损测量参数，2个闭环功控参数，RRC信令配置SRI与功控参数的关联关系时，功控参数只能在该TRP 0所对应的SRS resource set 0的功控参数池中选择。同样的，对SRS resource set 1，RRC信令配置SRI与功控参数的关联关系时，功控参数只能在该TRP 1所对应的SRS resource set 1的功控参数池中选择。针对不同SRS resource set，RRC信令配置SRI与功控参数的关联关系时，功控参数池的配置还可以是不区分TRP的。即不同的SRS resource set共享功控参数池。
在一实施例中，基站为每个SRS resource set配置对应的一组SRI与功控参数的关联关系，通过以下至少之一的方法实现：
分别为不同TRP或SRS resource set配置高层信令PUSCH-Config；
分别为不同TRP或SRS resource set配置高层信令PUSCH-PowerControl；
分别为不同TRP或SRS resource set配置高层信令sri-PUSCH-MappingToAddModList和sri-PUSCH-MappingToReleaseList；
分别为不同TRP或SRS resource set配置高层信令SRI-PUSCH-PowerControl集合；
分别为不同TRP或SRS resource set配置功控参数池。功控参数池包括开环功控参数池、闭环功控参数池，分别对应的高层信令为：p0-AlphaSets，twoPUSCH-PC-AdjustmentStates。功控参数池还包括路损测量参数，其对应的高 层信令为pathlossReferenceRSToAddModList和pathlossReferenceRSToReleaseList。其中，p0-AlphaSets中包括至少一个P0和alpha参数的集合，每一个P0和alpha参数的集合包括P0和/或alpha。
接着，对于上行传输为PUCCH传输的情况：
在一实施例中，PUCCH传输关联的空间关系只有一套编号，每个空间关系都被配置了一套功控参数。当指示的闭环功控数量为N时，按功控参数中的闭环功控参数将空间关系分为N部分。其中，N为大于1的整数。那么MAC CE指示PUCCH空间关系时，开销可以减小。
例如，预定义或预配置功控参数与TRP/CORESET组/PUCCH资源组的关联关系，至少包括闭环功控参数与TRP的关联关系。承载MAC CE的PDSCH所关联的DCI与TRP有关联，那么指示PUCCH空间关系的MAC CE可以间接地与TRP关联，进而，MAC CE只需要指示PUCCH resource与该TRP相关联的空间关系。相比指示所有TRP关联的空间关系，上述方法只需要指示部分空间关系，因此可以减小开销。例如，上述N＝2时，假设空间关系有8个，其中前4个空间关系被配置了闭环功控的编号0，而后4个空间关系被配置了闭环功控的编号1。闭环功控的编号0和闭环功控的编号1分别与TRP 0和TRP 1相关联。那么在TRP 0所关联的CORESET 0上发送的DCI所触发的PDSCH传输所携带的MAC CE指示PUCCH资源与空间关系时，MAC CE只需要指示前4个空间关系。即MAC CE中的Si只有S0～S3有效。其余Si可以设置为保留值。当一个MAC CE中包含多个PUCCH resource的空间关系时，就可以减小指示PUCCH resource的空间关系的MAC CE的开销。
在另一实施例中，当基站采用多TRP传输的场景，需要UE的功率控制具有较强的灵活性，可以采用如下几种方式之一：
方式1：使用相关技术中的功控机制，扩充功控参数的上限数量。例如，开环功控参数、闭环功控参数、路损测量参数的至少之一的配置数量上限提升所支持的TRP的数量的倍数。例如，当支持TRP的数量为2时，将闭环功控数量上限从2提升2倍，即提高到4。这样闭环功控的编号0，1，2，3可以被配置给不同的TRP，实现不同TRP的独立功控。比如，TRP 0的闭环功控的编号为0和1，分别实现一个TRP上两个波束对(beam pair link)独立配置PUCCH的闭环功控。
方式2：不同TRP的closed loop倾向于独立更新。在不扩充闭环功控参数上限数量的情况下，限制不同的TRP，即使closed loop的ID相同，也分别独立使用TPC命令。
例如，闭环功控对于不同TRP独立维护。即DCI中承载的TPC命令只能用于更新DCI所关联的TRP对应的TPC命令。例如，当支持TRP的数量为2时，闭环功控数量上限为2。在TRP 0对应的CORESET 0中发送的DCI携带的TPC命令只能更新TRP 0所对应的闭环功控。在TRP 1对应的CORESET 1中发送的DCI携带的TPC命令只能更新TRP 1所对应的闭环功控。又如，CORESET组0发送的DCI中的TPC命令应用于对应pucch-PowerControl/PUCCH-SpatialRelationInfo组0的PUCCH资源；CORESET组1发送的DCI中的TPC命令应用于对应pucch-PowerControl/PUCCH-SpatialRelationInfo组1的PUCCH资源。这样的好处是每个TRP都能支持独立的最大2个闭环功控。
方式3：为PUCCH传输配置多套空间关系，每套空间关系与以下至少之一关联：TRP、CORESET或CORESET组、PUCCH资源(组)。或，为PUCCH传输配置一套空间关系，一套空间关系中包含至少一个空间关系，将一套空间关系分为N组，每组空间关系与以下至少之一关联：TRP、CORESET或CORESET组、PUCCH资源(组)指示PUCCH resource的空间关系的MAC CE指示PUCCH资源的所有的空间关系。或，指示PUCCH resource的空间关系的MAC CE仅指示其所关联的TRP所对应的空间关系。MAC CE所关联的TRP可以由以下之一方式获得：由指示PUCCH resource的空间关系的MAC CE所在的PDSCH的DCI所在的CORESET可以获得：指示PUCCH resource的空间关系的MAC CE的DCI所关联的TRP；或，由指示PUCCH resource的空间关系的MAC CE所在的PDSCH所在的资源与TRP的关联获得：发送指示PUCCH resource的空间关系的MAC CE的TRP。
由触发PUCCH传输的DCI可以获得：PUCCH resource indicator、触发PUCCH传输的DCI所关联的TRP。UE可以依据触发PUCCH传输的DCI所关联的TRP，获取在该TRP上发送的指示PUCCH resource的空间关系的MAC CE，从而获得该PUCCH传输所对应的PUCCH resource及其对应的空间关系，该空间关系是与TRP对应的。空间关系与功控参数的关联包括：基站为每套空间关系配置对应的一组空间关系与功控参数的关联关系。例如，针对TRP，RRC信令配置一组空间关系PUCCH-SpatialRelationInfo，每个PUCCH-SpatialRelationInfo中指示所关联的功控参数。PUCCH-SpatialRelationInfo中指示的所关联的功控参数是在功控参数池中配置对应的功控参数编号，至少包括以下之一：开环功控参数编号、闭环功控参数编号、路损测量参考信号。
功控参数池的配置是区分TRP的。例如，对TRP 0，功控参数池包括：2个开环功控参数，2个路损测量参数，2个闭环功控参数，RRC信令配置空间关系与功控参数的关联关系时，功控参数只能在该TRP 0所对应的功控参数池中 选择。同样的，对TRP 1，RRC信令配置空间关系与功控参数的关联关系时，功控参数只能在该TRP 1所对应的功控参数池中选择。功控参数池的配置还可以是不区分TRP的。即不同的TRP所对应的空间关系共享功控参数池。
在一实施例中，基站为每个SRS resource set配置对应的一组SRI与功控参数的关联关系，通过以下至少之一的方法实现：
分别为不同TRP配置高层信令PUCCH-Config；
分别为不同TRP配置高层信令pucch-PowerControl；如，2个TRP分别对应1个pucch-PowerControl。
分别为不同TRP配置高层信令PUCCH-SpatialRelationInfo集合；
分别为不同TRP配置功控参数池。
功控参数池包括开环功控参数池、闭环功控参数池，分别对应的高层信令为：p0-Set，twoPUCCH-PC-AdjustmentStates。功控参数池还包括路损测量参数，其对应的高层信令为pathlossReferenceRSs。
例如，将所有PUCCH-SpatialRelationInfo分成2组，每组对应1个TRP/CORESET组/PUCCH资源(组)，每组也对应一个pucch-PowerControl。
最后，对于上行传输为SRS传输的情况：
基站为UE配置至少一个SRS resource set，以及至少一个SRS resource。每个SRS resource set包括至少一个SRS resource。每个SRS resource set可以被配置为以下一种用途：波束管理，天线切换，基于码本的传输(CB)，基于非码本的传输(NCB)。每个SRS resource set还配置功控参数。对于开环功控参数和路损测量参数，直接配置相关参数的内容；而对于闭环功控参数，可以配置与PUSCH传输的闭环功控相同，或SRS独立的闭环功控。当SRS与PUSCH传输的闭环功控相同时，可能与PUSCH传输的闭环功控编号0或者闭环功控编号1相同。并且，SRS传输仅使用PUSCH传输的对应的闭环功控编号对应的本地闭环功控的数值，而不负责更新本地该闭环功控的数值。
对于用途为基于码本的传输或基于非码本的传输的SRS resource set，需要支持N个SRS resource sets，每个SRS resource set与以下至少之一关联：TRP、CORESET或CORESET组。例如，支持2个TRP时，在一个带宽部分(Bandwidth part，BWP)上配置2个用途为基于码本的传输的SRS resource sets，分别对应一个TRP，还配置2个用途为基于非码本的传输的SRS resource sets，分别对应一个TRP。N个SRS resource sets以TDM方式发送。对应不同TRP，CORESET或CORESET组的SRS resource set，分别对应不同的PUSCH传输的闭环功控参数。例如，对应不同TRP，CORESET或CORESET组的SRS resource set，分别 对应不同的TRP，CORESET或CORESET组对应的PUSCH传输的闭环功控参数。
当SRS resource set与PUSCH的闭环功控参数相同时，TRP，CORESET或CORESET组DCI中的TPC命令仅更新TRP，CORESET或CORESET组对应的PUSCH传输的闭环功控参数对应的本地闭环功控值。当SRS resource set与PUSCH的闭环功控参数不同时，TRP，CORESET或CORESET组DCI中的TPC命令仅更新TRP，CORESET或CORESET组对应的SRS传输的闭环功控参数对应的本地闭环功控值。除了上述CORESET和CORESET组与TRP关联外，还可能存在一类CORESET不与特定的TRP关联，也可以称为公共CORESET，或公共TRP CORSET。在公共CORESET上发送的DCI中包含的TPC命令对于所有的TRP关联的闭环功控参数都有效。即，在公共CORESET上发送的DCI中包含的TPC命令会更新所有的TRP关联的闭环功控参数对应的本地闭环功控值。
基站对UE的上行传输进行调度时，需要确定很多因素，包括时频资源、传输的速率、调制编码方式、多入多出(Multiple-Input Multiple-Output，MIMO)方式等，根据接收的质量，基站需要判断后续的调度需要调整哪些因素，如提高调制编码方式、提高发送功率等。但是基站并不清楚UE当前的发送功率，也不知道是否可以提高发送功率。因此存在一种机制，UE发送功率余量报告(Power Headroom Report，PHR)给基站，明确告知当前传输需要的发送功率与最大发送功率的差值。
那么当采用本申请实施例提供的功率控制方法，将至少一个空域资源信息与功率控制参数关联，为了使基站能够准确地获取PHR，还可以将PHR与TRP信息和/或CORESET信息关联。
所述PHR中包括与以下信息关联的PHR：承载所述PHR的PUSCH传输相关的TRP信息和/或CORESET信息。那么UE获取PHR，PHR与TRP信息或CORESET信息关联。在一实施例中，所述PHR中仅包括与以下信息关联的PHR：承载所述PHR的PUSCH传输相关的TRP信息和/或CORESET信息；不包括其他TRP信息或CORESET信息关联的PHR信息。
在一实施例中，根据以下信息之一确定承载所述PHR的PUSCH传输相关的TRP信息或CORESET信息：调度所述承载所述PHR的PUSCH传输的DCI所属的CORESET；激活所述承载所述PHR的PUSCH传输的DCI所属的CORESET；为所述承载所述PHR的PUSCH传输配置的TRP信息或CORESET信息。
调度所述承载所述PHR的PUSCH传输的DCI所属的CORESET，主要针 对承载所述PHR的PUSCH传输是grant based PUSCH传输的情况。激活所述承载所述PHR的PUSCH传输的DCI所属的CORESET，主要针对承载所述PHR的PUSCH传输是配置授权的类型2的PUSCH传输的情况。为所述承载所述PHR的PUSCH传输配置的TRP信息或CORESET信息，主要针对承载所述PHR的PUSCH传输是配置授权的类型1的PUSCH传输的情况。
其中CORESET信息包括以下之一：CORESET，CORESET组，CORESET索引，CORESET组索引；TRP信息包括以下之一：TRP，TRP组，TRP索引，TRP组索引。PHR中包括：调度承载PHR的PUSCH传输的DCI所关联的TRP信息或CORESET信息。
UE通过测量下行导频信号监控信道，当路损变化超过一定门限时会触发PHR。当UE有合适的上行发送机会时，UE会将PHR以MAC CE的形式发送给基站。在多载波系统中，UE发送给基站的PHR信息中包含所有激活的成员小区(component cell，CC)的PHR。路损变化量超过一定门限是指，相对于上次上报的PHR所对应的路损量的变化量。
除了上述路损变化超过门限，还有周期的作用。当超过一定时间没有发生PHR上报事件，PHR也会被触发。PHR包括真实PHR和虚拟PHR。虚拟PHR也叫参考PHR。真实PHR是基于真实上行传输计算的PHR。真实PHR为最大发送功率减去该真实的上行传输需要的发送功率。真实的上行传输需要的发送功率与以下参数至少之一相关：传输占用的频域宽度、传输占用的频域位置、传输的数据速率、传输的调制与编码策略(Modulation and Coding Scheme，MCS)、传输的格式、开环功控部分、闭环功控部分、路损补偿部分。虚拟PHR是基于参考上行传输计算的PHR。虚拟PHR是用最大发送功率减去参考传输的开环功控部分、闭环功控部分、路损补偿部分。参考传输是假定的传输，不是真实存在的传输，因此参考传输的功控参数是预先定义的参数。依据计算PHR所考虑的传输类型，以及传输的组合的不同，PHR可以区分为不同的类型。例如，类型1的PHR是针对PUSCH传输的，类型2的PHR是针对PUCCH传输或者PUCCH+PUSCH传输的，类型3的PHR是针对SRS传输的。
在一实施例中，在多TRP的传输场景，由于不同TRP与UE的链路是独立的，那么PHR也应该按照TRP分为不同组。PHR与以下至少之一关联：TRP、CORESET或CORESET组。UE为不同TRP独立维护PHR的机制，包括以下至少之一：分别测量来自不同TRP的下行RS计算该TRP相关的路损，当一个TRP的路损变化超过一定门限时，触发该TRP相关的PHR；分别为不同TRP独立维护PHR的上报周期；发送给特定TRP的PHR信息只包括与该TRP关联的PHR；例如，基站支持2个TRP，发送给第一个TRP的PHR信息只包括第 一个TRP关联的PHR。发送给第二个TRP的PHR信息只包括第二个TRP关联的PHR。在特定TRP，CORESET或CORESET组上发送的DCI中调度的PUSCH中包含的PHR信息只包括与该TRP，CORESET或CORESET组关联的PHR。
在一实施例中，在多TRP的传输场景，由于不同TRP与UE的链路是独立的，那么配置授权的PUSCH应该配置关联的TRP对应功控参数。基站为不同TRP相关联的配置授权的PUSCH，通过以下至少之一的方法实现不同的功控参数：分别为不同TRP配置高层信令ConfiguredGrantConfig；分别为不同TRP配置高层信令的开环功控参数、闭环功控参数、以及路损测量参数，例如，p0-PUSCH-Alpha，powerControlLoopToUse，pathlossReferenceIndex。这些开环功控参数、闭环功控参数、以及路损测量参数，指示的是PUSCH的功控参数池中相应的参数的编号。因此可以分为两种情况：为不同的TRP配置独立的PUSCH的功控参数池，则配置授权的PUSCH的TRP相关的高层信令的开环功控参数、闭环功控参数、以及路损测量参数，是从各TRP关联的PUSCH的功控参数池中指示。只有一套PUSCH的功控参数池，则配置授权的PUSCH的TRP相关的高层信令的开环功控参数、闭环功控参数、以及路损测量参数，从这一套PUSCH的功控参数池中指示。至少以下之一与TRP相关，即不同的TRP需要独立配置：开环功控参数，闭环功控参数，路损测量参数。
例如，基站为UE用参数ConfiguredGrantConfig配置配置授权的PUSCH的参数。在支持多TRP的场景，基站可以为UE配置至少一个ConfiguredGrantConfig，每个ConfiguredGrantConfig中可以包括TRP信息或CORESET信息(用GroupId标识)。如下所示：
Figure PCTCN2020080671-appb-000022
在ConfiguredGrantConfig中包含TRP信息或CORESET信息，可以是直接包含在ConfiguredGrantConfig中，用于配置授权的PUSCH的类型1和类型2。也可以在ConfiguredGrantConfig中专用于类型1的参数rrc-ConfiguredUplinkGrant中配置，则仅用于配置授权的PUSCH的类型1。
Figure PCTCN2020080671-appb-000023
Figure PCTCN2020080671-appb-000024
还可以在configuredGrantConfig的上层参数中包括多个configuredGrantConfig参数，分别用于不同GroupId对应的TRP信息或CORESET信息。此处以2个GroupId为例，多个GroupId很容易扩展，就不再赘述：
