具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本公开相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本公开的一些方面相一致的装置和方法的例子。
为了便于理解，首先介绍本公开涉及的术语。
1、传输配置指示(transmission configuration indication，TCI)
用于告知终端设备物理下行控制信道(physical downlink control channel，PDCCH)、物理下行共享信道(physical downlink shared channel，PDSCH)对应的解调参考信号，与网络设备发送的哪个同步信号块(Synchronization Signal Block，SSB)或信道状态信息参考信号(channel state information reference signal，CSI-RS)为共站址；或告知终端设备物理上行控制信道(physical uplink control channel，PUCCH)、物理上行共享信道(physical uplink shared channel，PUSCH)对应的解调参考信号与终端发送的哪个参考信号(比如SRS)或基站发送的哪个SSB或CSI-RS为共站址。其中共站址包含以下传输参数之一：平均时延，时延扩展，多普勒频移，多普勒扩展，空间关系信息，和空间接收参数。
2、发射接收节点TRP
TRP相当于传统的基站，但在一些情况下，一个小区可能不止一个trp来覆盖，而是由多个trp联合覆盖。
3、下行控制信息(downlink control information，DCI)
由下行物理控制信道(physical downlink control channel，PDCCH)承载的，网络设备发给终端设备的下行控制信息，包括上下行资源分配、混合自动重传请求(Hybrid Automatic Repeat reQuest，HARQ)信息、功率控制等。
4、参考信号(reference signal，RS)
参考信号就是“导频”信号，是由发射端提供给接收端用于信道估计或信道探测的一种已知信号。可以用于终端设备的相干检测和解调、波束测量、信道状态信息测量或网络设备的相干检测和监测、或信道质量测量等。
请参见图1，图1为本公开实施例提供的一种通信系统的架构示意图。该通信系统可包括但不限于一个网络设备，比如TRP和一个终端设备，图1所示的设备数量和形态仅用于举例并不构成对本公开实施例的限定，实际应用中可以包括两个或两个以上的网络设备，两个或两个以上的终端设备。图1所示的通信系统以包括一个网络设备11、一个终端设备12为例。
需要说明的是，本公开实施例的技术方案可以应用于各种通信系统。例如：长期演进(long term evolution，LTE)系统、第五代(5th generation，5G)移动通信系统、5G新空口(new radio，NR)系统，或者其他未来的新型移动通信系统等。
本公开实施例中的网络设备11包括演进型基站(evolved NodeB，eNB)、传输点(transmission reception point，TRP)、NR系统中的下一代基站(next generation NodeB，gNB)、其他未来移动通信系统中的基站或无线保真(wireless fidelity，WiFi)系统中的接入节点等。本公开的实施例对网络设备所采用的具体技术和具体设备形态不做限定。本公开实施例提供的网络设备可以是由集中单元(central unit，CU)与分布式单元(distributed unit，DU)组成的，其中，CU也可以称为控制单元(control unit)，采用CU-DU的结构可以将网络设备，例如基站的协议层拆分开，部分协议层的功能放在CU集中控制，剩下部分或全部协议层的功能分布在DU中，由CU集中控制DU。
本公开实施例中的终端设备12是用户侧的一种用于接收或发射信号的实体，如手机。终端设备也可以称为终端设备(terminal)、用户设备(user equipment，UE)、移动台(mobile station，MS)、移动终端设备(mobile terminal，MT)等。终端设备可以是具备通信功能的汽车、智能汽车、手机(mobile phone)、穿戴式设备、平板电脑(Pad)、带无线收发功能的电脑、虚拟现实(virtual reality，VR)终 端设备、增强现实(augmented reality，AR)终端设备、工业控制(industrial control)中的无线终端设备、无人驾驶(self-driving)中的无线终端设备、远程手术(remote medical surgery)中的无线终端设备、智能电网(smart grid)中的无线终端设备、运输安全(transportation safety)中的无线终端设备、智慧城市(smart city)中的无线终端设备、智慧家庭(smart home)中的无线终端设备等等。本公开的实施例对终端设备所采用的具体技术和具体设备形态不做限定。
可以理解的是，本公开实施例描述的通信系统是为了更加清楚的说明本公开实施例的技术方案，并不构成对于本公开实施例提供的技术方案的限定，本领域普通技术人员可知，随着系统架构的演变和新业务场景的出现，本公开实施例提供的技术方案对于类似的技术问题，同样适用。
通常，在信道由多TRP与单TRP动态切换的情况下，通过添加独立的额外信令指示使用多套TCI状态中的一套或多套TCI状态作为切换后的TRP的TCI状态时，由于额外信令指示的各TCI状态的使用时间不确定，可能导致网络设备和终端设备在同一时刻使用的TCI状态不一致，因此可能对基于TCI状态的传输的性能产生影响。
本公开中，可以准确确定额外信令指示的TCI状态的使用时间，以保证网络设备和终端设备对第二TCI状态的使用时间的理解是一致的，从而保证网络设备和终端设备在同一时刻使用的TCI状态一致，提高了基于TCI状态的传输的性能。
需要说明的是，本公开中，任一个实施例提供的一种传输配置指示TCI状态使用时间的确定方法可以单独执行，或是结合其他实施例中的可能的实现方法一起被执行，还可以结合相关技术中的任一种技术方案一起被执行。
现结合附图和具体实施方式对本公开实施例进一步说明。
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本公开实施例相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本公开的一些方面相一致的装置和方法的例子。
在本公开实施例使用的术语是仅仅出于描述特定实施例的目的，而非旨在限制本公开实施例。在本公开实施例和所附权利要求书中所使用的单数形式的“一种”和“该”也旨在包括多数形式，除非上下文清楚地表示其他含义。还应当理解，本文中使用的术语“和/或”是指并包含一个或多个相关联的列出项目的任何或所有可能组合。
取决于语境，如在此所使用的词语“如果”及“响应于”可以被解释成为“在……时”或“当……时”或“响应于确定”。
下面详细描述本公开的实施例，所述实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的要素。下面通过参考附图描述的实施例是示例性的，旨在用于解释本公开，而不能理解为对本公开的限制。
请参见图2，图2是本公开实施例提供的一种传输配置指示TCI状态使用时间的确定方法流程示意图，该方法由终端设备执行。如图2所示，该方法可以包括但不限于如下步骤：
步骤201，接收第一指示信息，第一指示信息用于指示至少一个和/或至少一对第一TCI状态。
其中，一个TCI状态state，可以为一个联合(Joint)TCI state或一个下行(downlink，DL)TCI state，或一个上行(uplink，UL)TCI state。一对TCI状态，表示一个DL TCI state和一个UL TCI state。
步骤202，接收第二指示信息，第二指示信息用于指示指定信道和/或指定信号传输时使用的第二TCI状态，第二TCI状态为第一TCI状态中的部分或全部。
其中，指定信道可以包括以下至少一项：物理下行控制信道(physical downlink control channel，PDCCH)，物理下行共享信道(physical downlink shared channel，PDSCH)，物理上行控制信道(physical uplink control channel，PUCCH)，物理上行共享信道(physical uplink shared channel，PUSCH)。指定信号可以为信道状态信息参考信号(channel state information-reference signal，CSI-RS)，信道探测参考信号(sounding reference signal，SRS)，定位参考信号(positioning reference signal，PRS)，跟踪参考信号(tracking reference signal，TRS)等，本公开对此不作限制。
本公开中，每个指定信道和/或指定信号传输进行传输时，可以使用第一TCI状态中的部分或全部TCI状态，因此，网络设备可以通过向终端设备发送第二指示信息，以指示指定信道和/或指定信号传输时使用的第二TCI状态。比如第一TCI状态包含两个TCI状态，第二指示信息指示第二TCI状态为两个TCI状态中的第一个TCI状态，或第二指示信息指示第二TCI状态为两个TCI状态中的第二个TCI状态，或第二指示信息指示第二TCI状态为第一TCI状态中的两个TCI状态。
可选的，网络设备可以针对PDCCH向终端设备发送至少一个第二指示信息，用于指示控制资源集CORESET标识对应的PDCCH传输时使用的TCI状态，或指示CORESET池索引对应的PDCCH传输 时使用的TCI状态，或者搜索空间集(selective search set，SS set)组标识对应的PDCCH传输时使用的TCI状态，或者CORESET组标识对应的PDCCH传输时使用的TCI状态。
可选的，网络设备可以针对PUSCH向终端设备发送至少一个第二指示信息，用于指示动态调度的PUSCH传输时使用的TCI状态，或者指示配置授权类型1的PUSCH传输时使用的TCI状态，或者指示配置授权类型2的PUSCH传输时使用的TCI状态。
步骤203，确定第二TCI状态的使用时间。
本公开中，终端设备在确定每个指定信道和/或指定信号传输时使用的第二TCI状态后，即可基于指定的规则或者协议约定，确定第二TCI状态的使用时间。同样的，网络设备也可以基于指定的规则或协议约定，确定第二TCI状态的使用时间，从而保证网络设备与终端设备对第二TCI状态的使用时间理解一致。
比如，可以确定第二TCI状态的使用时间位于混合自动重传请求响应(hybrid automatic repeat request acknowledge，HARQACK)对应的PUCCH占用的时隙之后的指定数量个时隙后。其中，HARQ ACK可以为包含第二TCI状态信令的HARQ ACK。
本公开中，终端设备在接收用于指示至少一个和/或至少一对第一TCI状态第一指示信息后，可以接收用于指示指定信道和/或指定信号传输时使用的第二TCI状态的第二指示信息，之后，可以确定第二TCI状态的使用时间。由此，可使终端设备和网络设备对第二TCI状态的使用时间的理解一致，从而保证网络设备和终端设备在同一时刻使用的TCI状态一致，提高了基于TCI状态的传输的性能。
请参见图3，图3是本公开实施例提供的一种传输配置指示TCI状态使用时间的确定方法流程示意图，该方法由终端设备执行。如图3所示，该方法可以包括但不限于如下步骤：
步骤301，接收第一指示信息，第一指示信息用于指示至少一个和/或至少一对第一TCI状态。
步骤302，接收第二指示信息，第二指示信息用于指示指定信道和/或指定信号传输时使用的第二TCI状态，第二TCI状态为第一TCI状态中的部分或全部。
本公开中，步骤301-步骤302的具体过程，可参见本公开任一实施例的详细描述，在此不再赘述。
步骤303，响应于第二指示信息在第一MAC CE中，确定使用时间位于第一混合自动重传请求HARQ响应ACK对应的第一PUCCH占用的时隙之后的第一指定数量个时隙后，第一HARQ ACK为针对第一MAC CE的HARQ ACK。
可选的，网络设备可以将第二指示信息配置在媒体接入控制(medium access control，MAC)控制单元(control element,CE)中。由此，终端设备在接收到MACCE时，即可确定第二指示信息中的第二TCI状态。
当第二指示信息在第一MAC CE中时，终端设备在接收到第一MAC CE后，可以向网络设备返回针对第一MAC CE的第一HARQ ACK，因此，可以将第二TCI状态的使用时间确定为该第一HARQ ACK对应的第一PUCCH占用的时隙之后的第一指定数量个时隙slot后。由此，终端设备和网络设备，都可以根据第一PUCCH占用的时隙及第一指定数量，确定第二TCI状态的使用时间，从而保证终端设备与网络设备对第二TCI状态的使用时间的理解一致，从而保证网络设备和终端设备在同一时刻使用的TCI状态一致，提高了基于TCI状态的传输的性能。此外，第一指定数量可以是预先设置的，或者是协议约定的，或是网络设备指示的，本公开对此不作限制。
比如，假设第一指定数量为3，第一PUCCH占用的时隙为第一个slot，第二TCI状态的使用时间为第5个时隙开始之后的时隙。
此外，当预设在第一PUCCH占用的时隙之后的预设时长开始使用第二TCI状态时，由于一个子帧所包含的时隙数量与SCS存在相关关系，此时，可以根据第一PUCCH的子载波间隔SCS确定第一指定数量。一个子帧即1毫秒所包含的时隙数量与SCS的对应关系如表1所示：
表1
μ 子载波间隔 子帧包含的时隙数量
0 15KHz 1
1 30KHz 2
2 60KHz 4
3 120KHz 8
4 240KHz 16
5 480KHz 32
比如，当预设在第一PUCCH占用的时隙之后的3ms之后开始使用第二TCI状态，且子载波间隔对应值μ为1时，根据表1可以确定此时每个子帧包含的时隙数为2，又因为一个子帧时长为1ms，从而确定3ms包含3个子帧，进而确定3ms包含6个时隙，因此可以确定在第一PUCCH占用的时隙之后的第6个时隙之后，也就是最早在第一PUCCH占用的时隙之后的第7个时隙可以开始使用第二TCI状态。
可选的，第一MAC CE还可以包含第一指示信息，即第一指示信息与第二指示信息在同一MACCE中。其中，第一TCI状态的使用时间可以为第一HARQ ACK对应的第一PUCCH占用的时隙之后的预设指定数量个时隙后。此外，预设指定数量可以与第一指定数量相同也可以不同，即第一TCI状态的使用时间与第二TCI状态的使用时间相同或不同，本公开对此不作限制。
可选的，可以将第一指示信息与第二指示信息配置于不同的MAC CE中，可以将第一指示信息配置在第二MAC CE中，利用第二MAC CE指示第一TCI状态。
可选的，由于DCI中TCI域(field)中的一个码点可以对应多个TCI状态，或者DCI中TCI域(field)中的一个码点可以对应多对TCI状态，或者DCI中TCI域(field)中的一个码点可以对应一个TCI状态和一对TCI状态，或者DCI中TCI域(field)中的一个码点可以对应多个TCI状态和多对TCI状态，或者DCI中TCI域(field)中的一个码点可以对应一个TCI状态和多对TCI状态，或者DCI中TCI域(field)中的一个码点可以对应多个TCI状态和一对TCI状态等。因此，第一指示信息可以包括第二MAC CE及第一DCI，其中，第二MAC CE用于激活第一DCI中TCI域的多个码点中每个码点分别对应的至少一个和/或至少一对第一TCI状态，第一DCI用于指示多个码点中的一个码点。
也就是说，网络设备可以先通过第二MAC CE激活多个码点分别对应的至少一个和/或至少一对第一TCI状态，之后再通过DCI指示多个码点中的一个码点，从而终端设备即可基于指示的一个码点对应的至少一个和/或至少一对第一TCI状态，确定第一TCI状态。进一步终端设备接收第二指示信息，第二指示信息指示第二TCI状态，第二TCI状态为第一TCI状态的全部或部分，从而终端设备基于第一指示信息和第二指示信息确定指定信道或信号对应的第二TCI状态，即明确指定信道或信号与哪个或哪对TCI状态指示的参考信号准共址。
需要说明的是，第一指示信息和第二指示信息由网络设备独立指示。
一个实施例中，若在当前时刻,网络设备指示了新的第一TCI状态，而第二TCI状态不变，则可以根据下一时刻及第一TCI状态的使用时间，确定下一时刻对应的第一TCI状态和/或第二TCI状态。比如第一时间，第一TCI状态为TCI#1和TCI#2，第二TCI状态为第一TCI状态中的第一个即TCI#1。第二时间，网络设备发送第一指示信息指示第一TCI状态为TCI#3和TCI#4，而没有发送第二指示信息。那么在第三时间时，若第三时间在第一TCI状态的使用时间之前，第一TCI状态还是TCI#1和TCI#2，第二TCI状态为第一TCI状态中的第一个即TCI#1；若第三时间在第一TCI状态的使用时间之后，第一TCI状态是TCI#3和TCI#4，第二TCI状态为第一TCI状态中的第一个即TCI#3。
一个实施例中，若在当前时刻,网络设备指示新的第二TCI状态，而第一TCI状态不变，则可以根据下一时刻及第二TCI状态的使用时间，确定下一时刻对应的第二TCI状态。比如第一时间，第一TCI状态为TCI#1和TCI#2，第二TCI状态为第一TCI状态中的第一个即TCI#1。第二时间，网络设备没有发送第一指示信息，但发送第二指示信息指示第二TCI状态为第一TCI状态中的第二个。那么在第三时间时，若第三时间在第二TCI状态的使用时间之前，第二TCI状态为第一TCI状态中的第一个即TCI#1；若第三时间在第二TCI状态的使用时间之后，第二TCI状态为第一TCI状态中的第二个即TCI#2。
一个实施例中，若在当前时刻,网络设备指示新的第一TCI状态和新的第二TCI状态，则可以根据下一时刻、第一TCI状态的使用时间及第二TCI状态的使用时间，确定下一时刻对应的第二TCI状态 及第一TCI状态。比如第一时间，第一TCI状态为TCI#1和TCI#2，第二TCI状态为第一TCI状态中的第一个即TCI#1。第二时间，网络设备发送第一指示信息指示第一TCI状态为TCI#3和TCI#4，发送第二指示信息指示第二TCI状态为第一TCI状态中的第二个TCI。那么在第三时间时，若第三时间在第一TCI状态和第二TCI状态的使用时间之前，那么第一TCI状态为TCI#1和TCI#2，第二TCI状态为第一TCI状态中的第一个即TCI#1。若第三时间在第一TCI状态的使用时间之后、第二TCI状态的使用时间之前，那么第一TCI状态为TCI#3和TCI#4，第二TCI状态为第一TCI状态中的第一个即TCI#3。若第三时间在第一TCI状态的使用时间之前、第二TCI状态的使用时间之后，那么第一TCI状态为TCI#1和TCI#2，第二TCI状态为第一TCI状态中的第二个即TCI#2。若第三时间在第一TCI状态的使用时间之后、第二TCI状态的使用时间之后，那么第一TCI状态为TCI#3和TCI#4，第二TCI状态为第一TCI状态中的第二个即TCI#4。
本公开中，终端设备在接收用于指示至少一个和/或至少一对第一TCI状态第一指示信息后，可以接收用于指示指定信道和/或指定信号传输时使用的第二TCI状态的第二指示信息，之后，在第二指示信息在第一MAC CE的情况下，确定使用时间位于针对第一MAC CE的第一混合自动重传请求HARQ响应ACK对应的第一PUCCH占用的时隙之后的第一指定数量个时隙后。由此，可使终端设备和网络设备对第二TCI状态的使用时间的理解一致，从而保证网络设备和终端设备在同一时刻使用的TCI状态一致，提高了基于TCI状态的传输的性能。

本公开中，当包含第二指示信息的第一DCI为下行DCI时，终端设备在接收到第一DCI后，可以向网络设备返回针对第一DCI或针对第一DCI调度的PDSCH的第二HARQ ACK，因此，终端设备和网络设备可以将位于第二HARQ ACK反馈对应的PUCCH或PUSCH之后的第三指定数量的符号之后的时隙和/或符号确定为第二TCI状态的使用时间。其中，第二HARQ ACK为针对第一DCI的或针对第一DCI调度的PDSCH的HARQ ACK。其中，第三指定数量可以是预先设置的，或者是协议约定的，或是网络设备指示的，本公开对此不作限制。

请参见图10，图10是本公开实施例提供的一种传输配置指示TCI状态使用时间的确定方法流程示意图，该方法由网络设备执行。如图10所示，该方法可以包括但不限于如下步骤：
步骤1001，发送第一指示信息，第一指示信息用于指示至少一个和/或至少一对第一TCI状态。
其中，一个TCI状态state，可以为一个联合(Joint)TCI state或一个下行(downlink，DL)TCI state，或一个上行(uplink，UL)TCI state。一对TCI状态，表示一个DL TCI state和一个UL TCI state。
步骤1002，发送第二指示信息，第二指示信息用于指示指定信道和/或指定信号传输时使用的第二TCI状态，第二TCI状态为第一TCI状态中的部分或全部。
其中，指定信道可以包括以下至少一项：物理下行控制信道(physical downlink control channel，PDCCH)，物理下行共享信道(physical downlink shared channel，PDSCH)，物理上行控制信道(physical uplink control channel，PUCCH)，物理上行共享信道(physical uplink shared channel，PUSCH)。指定信号可以为信道状态信息参考信号(channel state information-reference signal，CSI-RS)，信道探测参考信号(sounding reference signal，SRS)，定位参考信号(positioning reference signal，PRS)，跟踪参考信号(tracking reference signalTRS)等，本公开对此不作限制。
本公开中，每个指定信道和/或指定信号传输进行传输时，可以使用第一TCI状态中的部分或全部TCI状态，因此，网络设备可以通过向终端设备发送第二指示信息，以指示指定信道和/或指定信号传输时使用的第二TCI状态。比如第一TCI状态包含两个TCI状态，第二指示信息指示第二TCI状态为两个TCI状态中的第一个TCI状态，或第二指示信息指示第二TCI状态为两个TCI状态中的第二个TCI状态，或第二指示信息指示第二TCI状态为第一TCI状态中的两个TCI状态。
可选的，网络设备可以针对PDCCH向终端设备发送至少一第二指示信息，用于指示控制资源集CORESET标识对应的PDCCH传输时使用的TCI状态，或指示CORESET池索引对应的PDCCH传输时使用的TCI状态，或者搜索空间集(selective search set，SS set)组标识对应的PDCCH传输时使用的TCI状态，或者CORESET组标识对应的PDCCH传输时使用的TCI状态。
可选的，网络设备可以针对PUSCH向终端设备发送至少一第二指示信息，用于指示动态调度的PUSCH传输时使用的TCI状态，或者指示配置授权类型1的PUSCH传输时使用的TCI状态，或者指示配置授权类型2的PUSCH传输时使用的TCI状态。
步骤1003，确定第二TCI状态的使用时间。
本公开中，网络设备在发送第二指示信息后，即可基于与终端设备侧相同的指定的规则中或者协议约定，确定第二TCI状态的使用时间。从而保证二者对第二TCI状态的使用时间理解一致。
比如，可以确定第二TCI状态的使用时间位于混合自动重传请求响应(hybrid automatic repeat request acknowledge，HARQ ACK)对应的PUCCH占用的时隙之后的指定数量个时隙后。其中，HARQ ACK可以为包含第二TCI状态信令的HARQ ACK。
本公开中，网络设备在向终端设备发送用于指示至少一个和/或至少一对第一TCI状态的第一指示信息后，可以向终端设备发送用于指示指定信道和/或指定信号传输时使用的第二TCI状态的第二指示信息，之后，可以确定第二TCI状态的使用时间。由此，可使终端设备和网络设备对第二TCI状态的使用时间的理解一致，从而保证网络设备和终端设备在同一时刻使用的TCI状态一致，提高了基于TCI状态的传输的性能。
请参见图11，图11是本公开实施例提供的一种传输配置指示TCI状态使用时间的确定方法流程示意图，该方法由网络设备执行。如图11所示，该方法可以包括但不限于如下步骤：
步骤1101，发送第一指示信息，第一指示信息用于指示至少一个和/或至少一对第一TCI状态。
步骤1102，发送第二指示信息，第二指示信息用于指示指定信道和/或指定信号传输时使用的第二TCI状态，第二TCI状态为第一TCI状态中的部分或全部。
本公开中，步骤1101-步骤1102的具体实现过程，可参见本公开任一实施例的详细描述，在此不再赘述。
步骤1103，响应于第二指示信息在第一MAC CE中，确定使用时间位于第一混合自动重传请求HARQ响应ACK对应的第一PUCCH占用的时隙之后的第一指定数量个时隙后，第一HARQ ACK为针对第一MAC CE的HARQ ACK。
可选的，网络设备可以将第二指示信息配置在媒体接入控制(medium access control，MAC)控制单元(control element,CE)中。由此，终端设备在接收到MACCE时，即可确定第二指示信息中的第二TCI状态。
当第二指示信息在第一MAC CE中时，终端设备在接收到第一MAC CE后，可以向网络设备返回针对第一MAC CE的第一HARQ ACK，因此，网络设备和终端设备，可以将第二TCI状态的使用时间确定为该第一HARQ ACK对应的第一PUCCH占用的时隙之后的第一指定数量个时隙slot后。由此，可使终端设备和网络设备对第二TCI状态的使用时间的理解一致，从而保证网络设备和终端设备都可以根据第一PUCCH占用的时隙及第一指定数量，确定第二TCI状态的使用时间，从而保证终端设备与网络设备在同一时刻使用的TCI状态一致，提高了基于TCI状态的传输的性能。此外，第一指定数量可以是预先设置的，或者是协议约定的，或是网络设备指示的，本公开对此不作限制。
比如，假设第一指定数量为3，第一PUCCH占用的时隙为第一个slot，第二TCI状态的使用时间为第5个时隙开始之后的时隙。
此外，当预设在第一PUCCH占用的时隙之后的预设时长开始使用第二TCI状态时，由于一个子帧所包含的时隙数量与SCS存在相关关系，此时，可以根据第一PUCCH的子载波间隔SCS确定第一指定数量。一个子帧即1毫秒所包含的时隙数量与SCS的对应关系如表1所示。
比如，当预设在第一PUCCH占用的时隙之后的3ms之后开始使用第二TCI状态，且子载波间隔对应值μ为1时，根据表1可以确定此时每个子帧包含的时隙数为2，又因为一个子帧时长为1ms，从而确定3ms包含3个子帧，进而确定3ms包含6个时隙，因此可以确定在第一PUCCH占用的时隙之后的第6个时隙之后，也就是最早在第一PUCCH占用的时隙之后的第7个时隙可以开始使用第二TCI状态。
可选的，第一MAC CE还可以包含第一指示信息，即第一指示信息与第二指示信息在同一MAC CE中。其中，第一TCI状态的使用时间可以为第一HARQ ACK对应的第一PUCCH占用的时隙之后的预设指定数量个时隙后。此外，预设指定数量可以与第一指定数量相同也可以不同，即第一TCI状态的使用时间与第二TCI状态的使用时间相同或不同，本公开对此不作限制。
可选的，可以将第一指示信息与第二指示信息配置于不同的MAC CE中，可以将第一指示信息配置在第二MAC CE中，利用第二MAC CE指示第一TCI状态。
可选的，由于DCI中TCI域(field)中的一个码点可以对应多个TCI状态，或者DCI中TCI域(field)中的一个码点可以对应多对TCI状态，或者DCI中TCI域(field)中的一个码点可以对应一个TCI状态和一对TCI状态，或者DCI中TCI域(field)中的一个码点可以对应多个TCI状态和多对TCI状态，或者DCI中TCI域(field)中的一个码点可以对应一个TCI状态和多对TCI状态，或者DCI中TCI域(field)中的一个码点可以对应多个TCI状态和一对TCI状态等。因此，第一指示信息可以包括第二MAC CE及第一DCI，其中，第二MAC CE用于激活第一DCI中TCI域的多个码点中每个码点分别对应的至少一个和/或至少一对第一TCI状态，第一DCI用于指示多个码点中的一个码点。
也就是说，网络设备可以先通过第二MAC CE激活多个码点分别对应的至少一个和/或至少一对第一TCI状态，之后再通过DCI指示多个码点中的一个码点，从而终端设备即可基于指示的一个码点对应的至少一个和/或至少一对第一TCI状态，确定第一TCI状态。进一步终端设备接收第二指示信息，第二指示信息指示第二TCI状态，第二TCI状态为第一TCI状态的全部或部分，从而终端设备基于第一指示信息和第二指示信息确定指定信道或信号对应的第二TCI状态，即明确指定信道或信号与哪个或哪对TCI状态指示的参考信号准共址。
需要说明的是，第一指示信息和第二指示信息由网络设备独立指示。
一个实施例中，若在当前时刻,网络设备指示了新的第一TCI状态，而第二TCI状态不变，则可以根据下一时刻及第一TCI状态的使用时间，确定下一时刻对应的第一TCI状态。比如第一时间，第一TCI状态为TCI#1和TCI#2，第二TCI状态为第一TCI状态中的第一个即TCI#1。第二时间，网络设备发送第一指示信息指示第一TCI状态为TCI#3和TCI#4，而没有发送第二指示信息。那么在第三时间时，若第三时间在第一TCI状态的使用时间之前，第一TCI状态还是TCI#1和TCI#2，第二TCI状态为第一TCI状态中的第一个即TCI#1；若第三时间在第一TCI状态的使用时间之后，第一TCI状态是TCI#3和TCI#4，第二TCI状态为第一TCI状态中的第一个即TCI#3。
一个实施例中，若在当前时刻,网络设备指示新的第二TCI状态，而第一TCI状态不变，则可以根据下一时刻及第二TCI状态的使用时间，确定下一时刻对应的第二TCI状态。比如第一时间，第一TCI状态为TCI#1和TCI#2，第二TCI状态为第一TCI状态中的第一个即TCI#1。第二时间，网络设备没有发送第一指示信息，但发送第二指示信息指示第二TCI状态为第一TCI状态中的第二个即TCI#2。那么在第三时间时，若第三时间在第二TCI状态的使用时间之前，第二TCI状态为第一TCI状态中的 第一个即TCI#1；若第三时间在第二TCI状态的使用时间之后，第二TCI状态为第一TCI状态中的第二个即TCI#2。
一个实施例中，若在当前时刻,网络设备指示新的第一TCI状态和新的第二TCI状态，则可以根据下一时刻、第一TCI状态的使用时间及第二TCI状态的使用时间，确定下一时刻对应的第二TCI状态及第一TCI状态。比如第一时间，第一TCI状态为TCI#1和TCI#2，第二TCI状态为第一TCI状态中的第一个即TCI#1。第二时间，网络设备发送第一指示信息指示第一TCI状态为TCI#3和TCI#4，发送第二指示信息指示第二TCI状态为第一TCI状态中的第二个TCI。那么在第三时间时，若第三时间在第一TCI状态和第二TCI状态的使用时间之前，那么第一TCI状态为TCI#1和TCI#2，第二TCI状态为第一TCI状态中的第一个即TCI#1。若第三时间在第一TCI状态的使用时间之后、第二TCI状态的使用时间之前，那么第一TCI状态为TCI#3和TCI#4，第二TCI状态为第一TCI状态中的第一个即TCI#3。若第三时间在第一TCI状态的使用时间之前、第二TCI状态的使用时间之后，那么第一TCI状态为TCI#1和TCI#2，第二TCI状态为第一TCI状态中的第二个即TCI#2。若第三时间在第一TCI状态的使用时间之后、第二TCI状态的使用时间之后，那么第一TCI状态为TCI#3和TCI#4，第二TCI状态为第一TCI状态中的第二个即TCI#4。
本公开中，网络设备在向终端设备发送用于指示至少一个和/或至少一对第一TCI状态的第一指示信息后，再向终端设备发送用于指示指定信道和/或指定信号传输时使用的第二TCI状态的第二指示信息，之后，在第二指示信息在第一MAC CE的情况下，确定使用时间位于针对第一MAC CE的第一混合自动重传请求HARQ响应ACK对应的第一PUCCH占用的时隙之后的第一指定数量个时隙后。由此，可使终端设备和网络设备对第二TCI状态的使用时间的理解一致，从而保证网络设备和终端设备在同一时刻使用的TCI状态一致，提高了基于TCI状态的传输的性能。

其中，第一DCI之后可以为第一DCI的第一个符号之后，或者第一DCI之后也可以为第一DCI的最后一个符号之后。当第一DCI包含多个PDCCH候选candidate时，则第一DCI的最后一个符号为结束时间较晚的PDCCH candidate占用的最后一个符号。此外，第二指定数量可以是预先设置的，或者是协议约定的，或是网络设备指示的，本公开对此不作限制。
可选的，第一DCI中可以包含第一指示信息，即第一指示信息与第二指示信息包含于同一DCI中。其中，第一TCI状态的使用时间位于第二HARQ ACK反馈对应的PUCCH或PUSCH之后的第五指定数量的符号之后，第二HARQ ACK为针对第一DCI的HARQ ACK或针对第一DCI调度的PDSCH的HARQ ACK。此外，第五指定数量和第二指定数量可以相同也可以不同，即第一TCI状态的使用时间与第二TCI状态的使用时间相同或不同，本公开对此不作限制。

比如，假设一个slot包含14个符号，且第三指定数量为7，若第二HARQ ACK反馈对应的PUCCH或PUSCH位于第1个slot中的第2个符号，则在第1个slot中的第9个符号之后即最早第10个符号开始使用第二TCI状态。若第二HARQ ACK反馈对应的PUCCH或PUSCH位于第1个slot中的第12个符号，则在第2个slot中的第5个符号之后即最早第6个符号开始使用第二TCI状态。
