在实施例中，上述信息中TCI状态由以下信息之一描述：
描述方式一，基本TCI状态集合中的TCI状态编号，或基本TCI状态集合的子集中的TCI状态的编号。
在实施例中，基本TCI状态集合由基站为UE配置。该基本TCI状态集合包括至少一个TCI状态，用于确定PDCCH、PDSCH、CSI-RS、PUSCH、PUCCH、和/或SRS等信道或信号的传输参数。基本TCI状态集合中的TCI状态包括或关联功率控制参数。根据上行传输对应的TCI状态可以确定上行传输的功率控制参数。在实施例中，功率控制参数包括：路损测量参数、目标接收功率参数、路损补偿系数、和/或闭环功控参数。
在实施例中，不同的上行传输对功率控制参数的需求可能不同，功率控制参数包括：路损测量参数、PUSCH的目标接收功率参数、路损补偿系数、PUSCH的闭环功控参数、PUCCH的目标接收功率参数、PUCCH的闭环功控参数、和/或SRS的目标接收功率参数。
例如：对于PUSCH传输，根据调度或触发该PUSCH传输的DCI中指示的TCI状态，在基本TCI状态集合中对应的TCI状态的信息可以确定应用于PUSCH传输的功控参数。
描述方式二，第一TCI状态集合中的TCI状态编号，或第一TCI状态集合的子集中的TCI状态的编号。
在实施例中，第一TCI状态集合由基站通过高层信令或MAC CE为UE配置或激活。第一TCI状态集合包括至少一个TCI状态或TCI状态组合，且第一TCI状态集合是基本TCI状态集合的子集。第一TCI状态集合用于确定上行传输，例如PUSCH、PUCCH、和/或SRS等信道或信号的传输参数。第一TCI状态集合可能有多个，分别对应不同类型的上行传输。第一TCI状态集合也可能有1个，对应多种类型的上行传输。基本TCI状态集合同上述实施例的描述，在此不再赘述。
第一TCI状态集合中的TCI状态包括或关联功率控制参数。根据上行传输对应的TCI状态可以确定上行传输的功率控制参数。
第一TCI状态集合中一个TCI状态与基本TCI状态集合中相同TCI状态包括或关联的功率控制参数是不同类型的功率控制参数。即，功率控制参数中的参数可能分别与不同层次TCI状态集合关联。
例如，基本TCI状态集合中的TCI状态关联路损测量参数。第一TCI状态集合中的TCI状态关联其他功率控制参数，包括以下至少之一：目标接收功率、PUSCH的目标接收功率、PUCCH的目标接收功率、路损补偿系数、闭环功控参数、PUSCH的闭环功控参数、或PUCCH的闭环功控参数。在第一TCI状态集合是为PUSCH、PUCCH、和/或SRS分别配置的情况下，用于PUSCH、PUCCH、SRS的第一TCI状态集合分别关联与PUSCH、PUCCH、SRS相关的功率控制参数。
又如，第一TCI状态集合中的TCI状态关联路损测量参数，用于确定PUSCH传输、PUCCH传输、和/或SRS传输的路损测量参数。基本TCI状态集合中的TCI状态关联其他功率控制参数，包括以下至少之一：目标接收功率、PUSCH的目标接收功率、PUCCH的目标接收功率、路损补偿系数、闭环功控参数、PUSCH的闭环功控参数、或PUCCH的闭环功控参数。
第一TCI状态集合中一个TCI状态与基本TCI状态集合中相同TCI状态包括或关联的功率控制参数是相同类型的功率控制参数的情况下，使用第一TCI状态集合中的功率控制参数，或使用第一TCI状态集合与基本TCI状态集合中的功率控制参数中较新的一个。即功率控制参数中的参数可能与不同层次TCI状态集合关联。
MAC层的信息，例如第一TCI状态集合包括的或关联的功率控制参数用于更新基本TCI状态集合中相同的TCI状态包括或关联的功率控制参数。
使用第一TCI状态集合与基本TCI状态集合中的功率控制参数中较新的一个的前提是，第一TCI状态集合与功率控制参数的关联关系已经生效。例如，UE在接收到第一TCI状态集合与功率控制参数的关联关系的MAC CE的一段时间后生效。如UE发送了该MAC CE的确认(Acknowledge，ACK)信息后的3个子帧之后。
在第一TCI状态集合中包括多于1个TCI状态或一个TCI状态组合的情况下，需要进一步的调度信息，例如物理层的指示信息DCI基于第一TCI状态集合指示上行传输对应的TCI状态。
描述方式三，第二TCI状态集合或第二TCI状态集合的子集中的TCI状态编号，或第二TCI状态集合或第二TCI状态集合的子集中的TCI状态组合的编号。
在实施例中，第二TCI状态集合由基站通过高层信令或MAC CE为UE配置或激活。第二TCI状态集合是第一TCI状态集合的或基本TCI状态集合的子集，包括至少一个TCI状态，或至少一个TCI状态组合。第二TCI状态集 合可能有多个，分别对应不同类型的上行传输。第二TCI状态集合也可能有1个，对应多种类型的上行传输。第一TCI状态集合和基本TCI状态集合同上述。
在第二TCI状态集合中包括多于1个TCI状态或一个TCI状态组合的情况下，需要进一步的调度信息，例如物理层的指示信息DCI进一步基于第二TCI状态集合指示上行传输对应的TCI状态。
第二TCI状态集合中的TCI状态包括或关联功率控制参数。根据上行传输对应的TCI状态可以确定上行传输的功率控制参数。
第二TCI状态集合中一个TCI状态与基本TCI状态集合或第一TCI状态集合中相同TCI状态包括或关联的功率控制参数是不同类型的功率控制参数。即，功率控制参数中的参数可能分别与不同层次TCI状态集合关联。
例如，基本TCI状态集合和/或第一TCI状态集合中的TCI状态关联路损测量参数，用于PUSCH传输、PUCCH传输、和/或SRS传输。第二TCI状态集合中的TCI状态关联其他功率控制参数，包括以下至少之一：目标接收功率、PUSCH的目标接收功率、PUCCH的目标接收功率、路损补偿系数、闭环功控参数、PUSCH的闭环功控参数、PUCCH的闭环功控参数。
又如，第二TCI状态集合中的TCI状态关联路损测量参数，用于PUSCH传输、PUCCH传输、和/或SRS传输。基本TCI状态集合和/或第一TCI状态集合中的TCI状态关联其他功率控制参数，包括以下至少之一：目标接收功率、PUSCH的目标接收功率、PUCCH的目标接收功率、路损补偿系数、闭环功控参数、PUSCH的闭环功控参数、PUCCH的闭环功控参数。
在第二TCI状态集合是为PUSCH、PUCCH、和/或SRS分别配置的情况下，用于PUSCH、PUCCH、SRS的第二TCI状态集合分别关联与PUSCH、PUCCH、SRS相关的功率控制参数。
在一实现方式中，在MAC层为激活的TCI状态关联功率控制参数的情况下，功率控制参数的指示信息来自于预先配置的集合，也叫作功率控制参数集合。功率控制参数集合是由高层配置的。例如，PL-RS参数集合包括64个PL-RS信息，P0参数集合包括32个P0参数。在MAC CE为一个或多个TCI状态关联功率控制参数的情况下，指示一个PL-RS的开销需要6比特，指示一个P0需要5比特。
为了减小功率控制参数指示的开销，本实施例提出针对激活的TCI状态集合确定一个功率控制参数子集，称为激活的功率控制参数集合，包括如下方式：通过高层信令配置M个功率控制参数，例如M＝64，称为基本功率控制参数集合；通过高层信令或MAC信令从M个功率控制参数中选择N个功率控制参数， 其中N小于M，例如N＝4，N个功率控制参数称为激活功率控制参数集合；激活的功率控制参数集合用于确定激活的TCI状态的功率控制参数。
在实施例中，采用以下方式至少之一从M个功率控制参数中选择N个或N组功率控制参数：比特地图；预定义或配置参数。
在实施例中，比特地图的方式包括：长度为M的比特地图，每比特对应1个或1组功率控制参数的激活/去激活状态。在从M个功率控制参数中选择N个或N组功率控制参数的情况下，比特地图中的比特有N个为激活状态，比如，激活状态取值为1；或，长度为a*M的比特地图，每a比特对应1个功率控制参数的激活/去激活状态。a是大于或等于1的整数。
在实施例中，预定义或配置参数的方式包括：以预定义或配置参数的方式激活分组中的一个或多个分组。
在实施例中，激活的功率控制参数集合也可以通过DCI信息指示。
激活的功率控制参数集合的大小是可以配置的。例如，在基站侧波束之间受到干扰的差别比较小的情况下，激活的功率控制参数集合可以比较小，反之，激活的功率控制参数集合可以比较大。
在实施例中，激活的功率控制参数集合包括激活的路损测量参数集合、激活的目标接收功率参数集合、激活的路损补偿系数集合、激活的开环功控参数集合、和/或激活的闭环功控参数集合。对每个TCI状态或TCI状态组合分别关联激活的功率控制参数集合中的多个功率控制参数编号。
在实施例中，激活的功率控制参数集合包括至少一个激活的功率控制参数，每个激活的功率控制参数包括路损测量参数、目标接收功率参数、路损补偿系数、开环功控参数、和/或闭环功控参数。对每个TCI状态或TCI状态组合关联一个激活的功率控制参数集合中的功率控制参数编号。
在实施例中，为进一步减小P0/alpha的开销，同一个信令(例如MAC CE)中指示的多个TCI状态和TCI状态组合之间可以采用差分方式指示多个P0/alpha的值。例如，一个MAC CE中需要指示TCI状态0，TCI状态1，TCI状态0和1的组合分别对应3套功率控制参数，其中TCI状态0的P0值是采用指示激活的功率控制参数集合中P0参数的编号，而对TCI状态1以及TCI状态0和1的组合采用指示相对于TCI状态0的P0值的偏差值的方式指示。偏差值的指示方式由预定义方式和/或配置参数的方式确定。
在一实现方式中，调度或触发PUSCH传输的DCI指示该PUSCH传输相关的TCI状态，或者根据MAC CE信息获得PUSCH传输相关的TCI状态，根据PUSCH传输相关的TCI状态确定PUSCH传输的功率控制参数。PUSCH传输 相关的TCI状态包括一个或多个TCI状态。
根据PUSCH传输相关的TCI状态确定PUSCH传输的功率控制参数，包括以下至少之一：
方式1，根据PUSCH传输相关的TCI状态中包括的PUSCH的功率控制参数确定PUSCH传输的功率控制参数。
在实施例中，TCI状态的信息中包括功率控制参数，功率控制参数至少包括用于PUSCH传输的功率控制参数，功率控制参数中的部分功率控制参数，例如路损测量参数，也可以用于确定PUCCH传输、或SRS传输的功率。
方式2，根据PUSCH传输相关的TCI状态与PUSCH的功率控制参数的关联确定PUSCH的传输功率控制参数。例如，根据PUSCH传输的TCI状态查TCI状态与PUSCH的功率控制参数关联关系表确定PUSCH传输的功率控制参数。
在实施例中，TCI状态与PUSCH的功率控制参数关联关系表中包括至少1个TCI状态与PUSCH的功率控制参数关联关系。每个TCI状态与PUSCH的功率控制参数关联关系中包括以下至少之一：TCI状态与PUSCH的功率控制参数关联关系编号，TCI状态编号，PUSCH的功率控制参数，PUSCH的功率控制参数编号。
在实施例中，TCI状态编号是指特定TCI状态集合中的TCI状态的编号或TCI状态的编号的组合。特定TCI状态集合包括以下之一：为PDSCH、PDCCH(或控制资源集合CORESET)、PUSCH、PUCCH或SRS之一或组合配置的或激活的TCI状态集合、基本TCI状态集合、第一TCI状态集合、或第二TCI状态集合。
在实施例中，TCI状态与PUSCH的功率控制参数关联关系编号与至少1个TCI状态编号有关联关系。至少1个TCI状态编号由特定TCI状态集合中的TCI状态的编号和/或TCI状态的编号的组合确定。例如，特定TCI状态集合中包括2个TCI状态，则TCI状态编号为0、1，TCI状态编号的组合为0和1。TCI状态与PUSCH的功率控制参数关联关系编号0、1、2分别对应TCI状态编号为0、1、0和1。
在实施例中，TCI状态与PUSCH的功率控制参数关联关系编号与多于1个TCI状态编号有关联关系，多于1个TCI状态编号由特定TCI状态集合中TCI状态的编号的组合确定。此时，TCI状态与PUSCH的功率控制参数关联关系包括X套PUSCH的功率控制参数，X为0、1、或大于1的整数。在X＝0的情况下，即该TCI状态与PUSCH的功率控制参数关联关系不包括PUSCH的功 率控制参数，则TCI状态与PUSCH的功率控制参数关联关系编号对应的功率控制参数是TCI状态与PUSCH的功率控制参数关联关系编号对应的多个TCI状态编号分别对应的PUSHC的功率控制参数；在X＝1的情况下，则对应的1套功率控制参数应用于TCI状态与PUSCH的功率控制参数关联关系对应的多于1个TCI状态编号相关的PUSCH传输；在X大于1的情况下，则X套功率控制参数分别应用于该TCI状态与PUSCH的功率控制参数关联关系编号对应的多个TCI状态编号的X个分组相关的PUSCH传输。例如，一个TCI状态与PUSCH的功率控制参数关联关系对应2个TCI状态编号0和1，并且该TCI状态与PUSCH的功率控制参数关联关系中包括X＝2套PUSCH的功率控制参数，则2套PUSCH的功率控制参数分别对应TCI状态编号为0和1的PUSCH传输。又如，一个TCI状态与PUSCH的功率控制参数关联关系对应4个TCI状态编号0、1、2和3，并且该TCI状态与PUSCH的功率控制参数关联关系中包括X＝2套PUSCH的功率控制参数，则2套PUSCH的功率控制参数分别对应TCI状态编号为0到3的2个分组的PUSCH传输，其中4个TCI状态分为X＝2组是根据预定义的方式确定，或根据配置信息确定，如TCI状态编号0和1是第一分组，TCI状态编号为2、3是第二分组。
方式3，根据PUSCH传输相关的TCI状态所关联的探测参考信号资源指示(Sounding Reference Signal Resource Indication，SRI)确定PUSCH传输功率控制参数。例如，根据TCI状态所关联的SRI，查找SRI与PUSCH的功率控制参数的映射(mapping)关系表，以确定PUSCH传输的功率控制参数。
在实施例中，TCI状态中包括SRI信息。SRI信息指示SRS资源集合中的1个或多个SRS资源。
在实施例中，TCI状态与SRI信息有关联关系。例如，TCI状态中包括的1个或多个SRS resource编号与SRI所指示的1个或多个SRS resource编号一致。
图4是本申请实施例提供的一种不同层次的TCI状态的配置示意图。PUSCH 1的TCI状态从池#2、#1或#0(pool#2、#1或#0)中的TCI状态中指示。TCI状态在pool#1或#0中被配置关联了功率控制参数。因此PUSCH 1传输的功率控制参数可以根据其对应的TCI状态关联的功率控制参数确定。
PUSCH 2的TCI状态从pool#3中的TCI状态中指示。pool#3中的TCI状态中包括至少一个TCI状态组合ID，每个TCI状态组合ID指示一个或多个TCI状态。每个TCI状态组合ID与功率控制参数关联。TCI状态组合ID与功率控制参数关联关系由MAC CE或高层信令指示。
在一实现方式中，确定PUCCH传输相关的TCI状态，根据TCI状态确定PUCCH的功率控制参数。
根据以下之一确定PUCCH传输相关的TCI状态：PUCCH传输对应的PUCCH资源关联的PUCCH空间关系中包含的TCI状态；PUCCH传输对应的PUCCH资源关联的TCI状态。
在实施例中，基站通过高层信令，如RRC信令，为UE配置基本TCI状态集合，该基本TCI状态集合用于确定PDCCH、PDSCH、CSI-RS、PUSCH、PUCCH、和/或SRS等信道或信号的传输参数。
在实施例中，PUCCH传输相关的TCI状态来自于基本TCI状态集合，或基本TCI状态集合的子集第一TCI状态集合。第一TCI状态集合由高层信令或MAC CE基于基本TCI状态集合配置或激活。
或者，TCI状态来自于第二TCI状态集合，第二TCI状态集合是MAC CE激活的。第二TCI状态集合是基于基本TCI状态集合和/或第一TCI状态集合确定的，是基本TCI状态或第一TCI状态集合的子集。
在实施例中，第一TCI状态集合或第二TCI状态集合中每个TCI状态成员关联一套功率控制参数。TCI状态与功率控制参数的关联关系可以是由高层信令配置，和/或MAC信令配置或更新。
图5是本申请实施例提供的另一种不同层次的TCI状态的配置示意图。对于PUCCH传输，其对应的PUCCH资源与空间关系(记为spatial relation)有关联关系。
选择1：与PUCCH资源关联的空间(spatial)可能来自高层信令配置的PUCCH spatial relation参数池(pool)，该参数池中的PUCCH spatial relation指示PUCCH传输参考的TCI状态，该TCI状态来自pool#0，或#1中的TCI状态，可以分别对应基本波束状态集合，第一波束状态集合。根据上述参考的TCI状态(state)关联的功率控制参数确定该PUCCH传输的功率控制参数。
选择2：与PUCCH资源关联的spatial来自pool#2，#1或#0的TCI状态，可以分别对应第二波束状态集合，第一波束状态集合，和基本波束状态集合。图中的pool#2’是指对PUCCH单独配置的第二波束状态集合。Pool#2是PUCCH与其他传输共享的波束状态集合。根据与PUCCH资源关联的空间关系所对应的TCI状态关联的功率控制参数确定该PUCCH传输的功率控制参数。
在一实现方式中，可采用以下方式确定SRS功率控制参数。

根据SRS资源所关联的TCI状态所关联的功率控制参数确定该SRS资源对应的STS传输的功率控制参数。
在实施例中，对于特定用途的SRS，如波束管理，SRS资源集合中所有SRS资源的功率控制参数需要保持一致，则需要根据SRS资源集合中的所有SRS资源各自对应的功率控制参数确定一套功率控制参数。
在实施例中，SRS资源集合包括多个SRS资源分组，例如，在多传输点(Transmission Point，TRP)多面板(panel)的场景下，则需要根据SRS资源分组中的SRS资源各自对应的功率控制参数确定一套的功率控制参数用于对应的SRS资源分组。
在实施例中，根据SRS资源集合或SRS资源分组中的至少一个SRS资源对应的TCI状态所关联的至少1套功率控制参数确定一套功率控制参数的方法包括以下至少之一：SRS资源集合或SRS资源分组中特定SRS资源编号的，例如，编号最小的或最大的，SRS资源对应的TCI状态所关联的功率控制参数；SRS资源集合或SRS资源分组中所有SRS资源对应的TCI状态所关联的功率控制参数的平均值。
功控参数包括例P0参数，alpha参数，和/或PL-RS参数。在一实现方式中，对TCI状态与PC参数，以及SRS资源之间的关系进行描述。图6是本申请实施例提供的一种TCI状态与PC参数，以及SRS资源之间的关系示意图。

为了统一处理，对于PUSCH传输使用多于1个TCI状态的情况，也可以兼容PUSCH传输使用1个TCI状态，因此，调度或触发PUSCH传输的DCI中包括TCI状态指示信息，每个TCI状态指示信息的取值指示一个或多个TCI状态。
在实施例中，对于基于码本的PUSCH传输，调度或触发PUSCH的DCI中包括发射预编码矩阵指示(Transmitted Precoding Matrix Indication，TPMI)信息。为支持PUSCH传输使用多于1个TCI状态的情况，调度或触发PUSCH传输的DCI中包括至少1个TPMI信息。至少一个TPMI信息可以联合编码。
