另外，本领域普通技术人员可知，随着网络架构的演变和新业务场景的出现，本申请实施例提供的技术方案对于类似的技术问题，同样适用。
首先，对本申请实施例涉及的术语进行解释说明：
(1)波束(beam)
波束是一种通信资源，通过波束可以发送信息或接收信息。具体地，一个波束可以对应一个或多个天线端口，用于传输数据信道，控制信道和探测信号等。例如，发射波束可以是指信号经天线发射出去后在空间不同方向上形成的信号强度的分布，接收波束可以是指从天线上接收到的无线信号在空间不同方向上的信号强度分布。可以理解的是，形成一个波束的一个或多个天线端口也可以看作是一个天线端口集。当前3GPP标准协议中，对波束相关概念的协议规范主要用于确定终端设备的接收行为或发送行为，并保持网络侧(例如，基站)、终端设备分别对接收行为和发送行为的理解一致性。
(2)空间滤波传输器(Spatial filter)
根据3GPP协议Rel-15/Rel-16的规定，空间滤波传输器可以指示一组通信参数。终端设备可以通过(或使用)空间滤波传输器发送上行信道或上行信号，使用空间空间滤波传输器接收下行信道或下行信号。
(3)准同位(quasi-co-location，QCL)
QCL关系用于表示多个资源之间具有一个或多个相同或者相类似的通信特征，对于具有准共址关系的多个资源，可以采用相同或者类似的通信配置。具体的，具有QCL关系的天线端口对应的信号中具有相同的参数，或者，一个天线端口的参数(也可以称为QCL参数)可用于确定与该天线端口具有QCL关系的另一个天线端口的参数，或者，两个天线端口具有相同的参数，或者，两个天线端口间的参数差小于某阈值。其中，所述参数可以包括以下一项或多项：时延扩展(delay spread)，多普勒扩展(Doppler spread)，多普勒频移(Doppler shift)，平均时延(average delay)，平均增益，空间接收参数(spatial Rx parameters)。其中，空间接收参数可以包括以下的一项或多项：到达角(angle of arrival，简称AOA)、平均AOA、AOA扩展、离开角(angle of departure，简称AOD)、平均离开角AOD、AOD扩展、接收天线空间相关性参数、发送天线空间相关性参数、发射波束、接收波束以及资源标识。
(4)天线端口的QCL参数
天线端口的QCL参数用于指示通过天线端口发送的信道的DMRS与某个参考信号满足QCL关系，或者，通过天线端口发送的信号与某个参考信号满足QCL关系。
(5)传输配置指示(transmission configuration indicator，TCI)
TCI可以信道的QCL信息，其中，QCL信息可以指示信道或信号的解调参考信号(demodulation reference signal，DMRS)与哪个参考信号满足QCL关系，则终端设备可以采用与该参考信号的接收参数相同或相近的接收参数接收该信道或信号。
示例的，TCI用于指示物理下行控制信道(physical downlink control channel，PDCCH)或物理下行共享信道(physical downlink shared channel，PDSCH)的QCL 信息，即可以指示PDCCH/PDSCH的DMRS与哪个或哪些参考信号满足QCL关系，则终端可以采用与该参考信号的接收参数相同或相近的接收参数接收PDCCH/PDSCH。
一种可能的实现方式中，TCI具体可以指示参考信号索引，通过参考信号索引来指示与PDCCH/PDSCH的DMRS满足QCL关系的参考信号。接收参数可以包括接收波束等空间参数。
(6)参考信号(reference signal，RS)
在物理层，上行通信包括上行物理信道和上行信号的传输。其中上行物理信道包括随机接入信道(random access channel，PRACH)，上行控制信道(physical uplink control channel，PUCCH)，上行数据信道(physical uplink shared channel，PUSCH)等；上行信号包括信道探测信号SRS，上行控制信道解调参考信号(PUCCH de-modulation reference signal，PUCCH-DMRS)，上行数据信道解调参考信号PUSCH-DMRS，上行相位噪声跟踪信号(phase noise tracking reference signal，PTRS)，上行定位信号(uplink positioning RS)等等。上述上行信号可以称为参考信号。
下行通信包括下行物理信道和下行信号的传输。其中下行物理信道包括广播信道(physical broadcast channel，PBCH)，下行控制信道(physical downlink control channel，PDCCH)，下行数据信道(physical downlink shared channel，PDSCH)等；下行信号包括主同步信号(primary synchronization signal，简称PSS)/辅同步信号(secondary synchronization signal，SSS)，下行控制信道解调参考信号PDCCH-DMRS，下行数据信道解调参考信号PDSCH-DMRS，相位噪声跟踪信号PTRS，信道状态信息参考信号(channel status information reference signal，CSI-RS)，小区信号(Cell reference signal，CRS)(NR没有)，精同步信号(time/frequency tracking reference signal，TRS)(LTE没有)，LTE/NR定位信号(positioning RS)等。其中，上述下行信号可以称为参考信号。
(7)波束失败(beam failure)
通常基站与UE通过波束对进行通信，基站以发送波束的形式发送电磁波信号。电磁波信号在空间以波束形式传播的过程中，如果发送波束被物体遮挡，通过该波束传输的信号/信道则无法被接收端正确接收，接收端在一定时间内都无法通过配对的接收波束继续通信，认为发生波束失败。
一种可能的实现方式中，UE可以通过测量基站配置的CSI-RS进行波束失败检测。例如，CSI-RS的测量结果在一定时间内均低于阈值，UE可以判定波束失败。
另一种可能的实现方式中，如果基站没有为UE配置CSI-RS，UE可以检测下行接收波束所关联的参考信号，根据测量结果判断是否发生波束失败。其中，下行接收波束关联的参考信号与下行接收波束接收的下行信道的DMRS满足QCL关系，或者，下行接收波束关联的参考信号与下行接收波束接收的下行信号满足QCL关系。
例如，UE可以测量接收PDCCH的下行波束所关联的参考信号，即与PDCCH的DMRS具备QCL关系的参考信号，UE可以对该参考信号进行测量。当测量结果在一定时间内都低于一个阈值时，UE可以判定波束失败。
(8)波束失败恢复
UE可以维护候选波束(称为q_1，或candidate beam)，当UE判定波束失败， 可以执行波束失败恢复，以便UE通过候选波束确定新波束(q_new)和基站进行通信。在当前3GPP协议版本中(Rel-16)，基站最多为UE配置两个候选波束，UE通过测量最多两个候选波束，从中确定一个候选波束尝试进行波束失败恢复。当UE接收到基站发送的波束失败恢复响应消息后，该候选波束成为新波束。
示例的，参考图2，当UE测量波束2关联的参考信息，根据测量结果判定波束失败，则切换至候选波束4。UE通过波束4向基站发送波束失败恢复请求，若UE通过候选波束4接收到来自基站的波束失败恢复请求响应，则后续可以通过候选波束4与基站进行通信。当然，基站切换到波束3上与UE进行通信。
(9)公共波束
本申请实施例中，公共波束可以用于多个信道的传输，或者用于多个信号的传输。其中，所述多个信道或信号包括物理下行控制信道PDCCH、物理下行共享信道PDSCH、下行参考信号、物理上行控制信道PUCCH、物理上行共享信道PUSCH以及探测参考信号SRS中的至少两项。
公共波束可以是上下行公共波束、上行公共波束或下行公共波束。其中，上下行公共波束可以用于传输上行以及下行的一个或多个信号。例如，UE可以通过同一个波束接收PDCCH、PDSCH以及下行参考信号，发送PUCCH、PUSCH以及探测参考信号SRS。
上行公共波束可以用于多个上行信号的传输，例如，UE可以通过同一个波束发送PUCCH、PUSCH以及SRS。
下行公共波束可以用于多个下行信号的传输，例如，UE可以通过同一个波束接收PDCCH、PDSCH以及下行参考信号。
公共波束也可以被理解统一波束或统一TCI(Unified TCI)；公共波束还可以被理解为联合TCI(Joint TCI)。
3GPP Rel-15/Rel-16定义的TCI针对不同的下行信道是分别指示的，例如PDCCH和PDSCH信道适用于不同的TCI指示方法或信令。对于上行发送的指示，则基于空间关联关系(Spatial relation)。随着协议演进到Rel-17版本，“公共波束”的概念开始被讨论，标准期望使用一种相对统一的配置和/或指示方式，简化协议与信令设计，用于多个场景、信道、信号等的波束指示。
引入公共波束后，终端设备如何进行波束失败检测尚不明确，目前还没有技术方案能够支持终端设备在此场景下确定用于波束失败检测的波束。例如，基站为UE配置了公共TCI，该TCI中的参考源参考信号(source reference signal)为上行参考信号。在当前技术方案中，终端设备无法根据上行参考信号确定用于波束检测的下行接收波束。其中，公共TCI适用于多个信道，终端设备可以根据公共TCI确定公共波束，通过公共波束(或公共空间滤波传输器)发送多个信号或多个信道。
此外，假设基站指示的公共波束用于下行接收，当终端设备判定波束失败，终端设备如何进行波束失败恢复也尚不明确，以及终端设备如何确定新的公共波束也尚不明确，没有技术方案能够支持终端设备在此场景下进行波束失败恢复。
本申请实施例中，基站发送的TCI包括上行参考信号的信息和/或下行参考信号的信息。TCI指示的下行参考信号与多个下行信道的DMRS具备QCL关系，或者，与 一个或多个下行信号满足QCL关系。终端设备可以根据TCI指示的下行参考信号的接收参数确定下行接收波束失败检测参考信号，将下行接收波束失败检测参考信号作为波束失败检测的波束，或者终端设备将TCI指示的下行参考信号作为波束失败检测的波束。终端设备对下行TCI指示的下行参考信号，或者波束失败检测参考信号进行测量，根据测量结果判断是否发生波束失败。在公共波束场景下，支持终端设备进行波束失败检测。
或者，TCI指示的上行参考信号对应的空间滤波传输器(即接收所述上行参考信号的空间滤波传输器)可以用于发送一个或多个上行信道或信号，也可以用于接收多个下行信道或信号。终端设备可以根据该上行参考信号的发送参数确定下行接收波束，将所述下行接收波束作为波束失败检测的波束。对下行接收波束关联的下行参考信号进行测量，根据测量结果判断是否发生波束失败。在公共波束场景下，支持终端设备进行波束失败检测。
例如，参考图3，TCI包括下行参考信号1的信息，下行参考信号1与PDCCH以及PDSCH的DMRS满足QCL关系。终端设备可以确定下行参考信号1的接收参数为PDCCH以及PDSCH的接收参数，包括下行接收波束1。终端设备可以使用终端设备可以采用相同或相近的接收参数接收PDCCH、PDSCH以及所述第一参考信号。
终端设备还可以将下行接收波束1作为波束失败检测的波束，判断是否能够通过下行接收波束1接收到接入网设备发送的下行信号。具体地，可以对下行接收波束1关联的参考信号进行测量，根据测量结果判断是否发生波束失败。其中，下行接收波束1关联的参考信号与下行接收波束1接收的下行信道的DMRS满足QCL关系，例如，下行接收波束1关联的参考信号为所述下行参考信号1。
或者，TCI包括上行参考信号1的信息，上行参考信号1对应的空间滤波传输器可以用于发送PUCCH以及PUSCH。终端设备还可以通过上行参考信号1对应的空间滤波传输器接收下行信道或下行信号。即上行参考信号1对应的空间滤波传输器关联的波束可以是下行接收波束，终端设备可以对该下行接收波束关联的参考信号进行测量，基于测量结果判断是否发生波束失败。其中，该下行接收波束关联的参考信号可以是通过上行参考信号1对应的空间滤波传输器接收的下行参考信号。
需要说明的是，在本申请的描述中，“第一”、“第二”等字样仅仅是为了区分描述，并不用于对某个特征的特别限定。本申请实施例的描述中，“和/或”，描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。字符“/”一般表示前后关联对象是一种“或”的关系。本申请中所涉及的至少一个是指一个或多个；多个，是指两个或两个以上。

步骤502中，终端设备基于接入网设备发送的第一TCI进行波束失败检测，具体流程包括以下S1、S2：
S1、根据所述第一TCI确定用于波束失败检测的下行接收波束(以下简称为第一波束)。
具体实现中，终端设备可以根据第一TCI中的信息确定接收下行信道或信号的接收参数，或者，根据第一TCI中的信息确定接收下行信道或信号的空间滤波传输器，或者，根据第一TCI中的信息确定用于接收下行信道或信号的天线端口QCL参数。从而可以根据下行信道或信号的接收参数、接收下行信道或信号的空间滤波传输器或用于接收下行信道或信号的相同天线端口和/或相同天线面板的QCL参数确定下行接收波束，进一步终端设备还可以从确定的下行接收波束中确定用于波束失败检测的下行接收波束。
区别与第一TCI中不同的信息，终端设备具体可以通过以下三种方式确定用于波束失败检测的下行接收波束：
第一种、第一TCI包括第一下行参考信号的信息，终端设备确定多个下行信道的DMRS与第一下行参考信号满足QCL关系，可以根据第一下行参考信号确定用于波束失败检测的下行接收波束。
例如，根据第一TCI中的第一下行参考信号的信息，终端设备可以根据第一下行参考信号的接收参数接收PDCCH和PDSCH，或者，通过接收第一下行参考信号的空间滤波传输器接收PDCCH和PDSCH，或者，使用接收第一下行参考信号的相同天线端口和/或相同天线面板的QCL参数接收PDCCH和PDSCH。终端设备还可以根据第一下行参考信号的接收参数、接收第一下行参考信号的空间滤波传输器或接收第一下行参考信号的相同天线端口和/或相同天线面板的QCL参数确定PDCCH和PDSCH的下行接收波束。终端设备可以将PDCCH和PDSCH的下行接收波束作为波束失败检测的波束。
第二种、第一TCI包括第一上行参考信号的信息，终端设备可以根据第一上行参考信号确定用于波束失败检测的下行接收波束。
例如，根据第一TCI的指示，终端设备可以根据第一上行参考信号的发送参数确定PDCCH和PDSCH的接收参数，或者，通过发送第一上行参考信号的空间滤波传输器接收PDCCH和PDSCH，或者，使用发送第一下行参考信号的相同天线端口和/或相同天线面板的QCL参数接收PDCCH和PDSCH。终端设备还可以根据PDCCH和PDSCH的接收参数、接收PDCCH和PDSCH的空间滤波传输器或接收PDCCH和 PDSCH的天线端口QCL参数确定PDCCH和PDSCH的下行接收波束。终端设备可以将PDCCH和PDSCH的下行接收波束作为波束失败检测的波束。
第三种、第一TCI包括第一上行参考信号的信息和第一下行参考信号的信息，终端设备可以根据第一下行参考信号确定用于波束失败检测的下行接收波束。具体参考上述第二种实现方式，在此不做赘述。此外，可选的，终端设备可以根据第一上行参考信号的信息，确定发送波束失败恢复请求。
一种可能的实现方式中，在进行波束失败检测时，下行控制信道的接收波束优先与下行数据信道的接收波束，优先将下行控制信道的接收波束作为波束失败检测的波束。
示例的，TCI指示的公共波束用于接收PDSCH以及发送一个或多个上行信道。例如，TCI包括下行参考信号的信息，终端设备根据该下行参考信号的接收参数接收PDSCH，还可以根据该下行参考信号的接收参数确定一个或多个上行信道的发送参数。或者，通过接收该下行参考信号的空间滤波传输器接收PDSCH、发送一个或多个上行信道。
终端设备确定PDCCH的接收参数，或者，确定接收PDCCH的空间滤波传输器，从而确定PDCCH的下行接收波束，将PDCCH的下行接收波束作为波束失败检测的波束。
S2、对第一波束关联的下行参考信号(以下简称为目标下行参考信号)进行测量，基于测量结果判断是否发生波束失败。
具体地，第一波束关联的下行参考信号可以认为是用于波束失败检测的下行参考信号，终端设备对该下行参考信号进行测量，可以根据测量结果判断是否发生波束失败。另外，第一波束与目标下行参考信号的关联关系可以理解为：通过第一波束接收的下行信道的DMRS与目标下行参考信号满足QCL关系，或者，接收目标下行参考信号的空间滤波传输器与所述第一波束对应，或者，目标下行参考信号的接收参数包括所述第一波束。
区别于TCI的不同内容，终端设备可以通过以下三种可能的实现方式确定目标下行参考信号：
第一种、TCI仅包括第一下行参考信号的信息，TCI可以指示下行公共波束，即终端设备通过第一下行参考信号的接收参数接收多个下行信道，或者，通过接收第一下行参考信号的空间滤波传输器接收多个下行信道，或者，使用接收第一下行参考信号的相同天线端口和/或相同天线面板的QCL参数接收多个下行信道。
所述下行公共波束可以用于波束失败检测，即为前文所述的第一波束。通过所述下行公共波束接收的下行信道的DMRS与第一下行参考信号满足QCL关系，或者，接收第一下行参考信号的空间滤波传输器与所述下行公共波束对应，或者，第一下行参考信号的接收参数包括所述下行公共波束。基于此，第一波束关联的下行参考信号为所述第一参考信号。
第二种、TCI仅包括第一上行参考信号的信息，终端设备可以根据第一上行参考信号的发送参数确定多个下行信道的接收参数，或者，通过发送第一上行参考信号的空间滤波传输器接收多个下行信道，或者，使用发送第一上行参考信号的相同天线端 口和/或相同天线面板的QCL参数接收多个下行信道。
终端设备还可以根据第一上行参考信号的发送参数确定所述第一上行参考信号关联的下行参考信号(以下简称为下行参考信号s)，或者，通过发送第一上行参考信号的空间滤波传输器接收下行参考信号s，或者，使用发送第一上行参考信号的相同天线端口和/或相同天线面板的QCL参数接收下行参考信号s。
可以理解的是，根据接收参数、空间滤波传输器或天线端口QCL参数可以确定下行接收波束，该下行接收波束可以用于波束失败检测，即为前文所述的第一波束。参考前文的描述，下行参考信号s为第一波束关联的下行参考信号。
也就是说，当TCI仅包括第一上行参考信号的信息，第一波束关联的下行参考信号为第一上行参考信号关联的下行参考信号s，发送第一上行参考信号的空间滤波传输器可以用于接收下行参考信号s。
具体实现中，若目标下行参考信号的测量结果在一段时间内低于相应的阈值，则确定发生波束失败。反之，确定未发生波束失败。
示例的，测量所述第一下行参考信号，若测量结果在一段时间内低于相应的阈值，则确定发生波束失败。反之，确定未发生波束失败。
或者，测量所述第一上行参考信号关联的下行参考信号s，若测量结果在一段时间内低于相应的阈值，则确定发生波束失败。反之，确定未发生波束失败。
需要说明的是，现有技术没有涉及公共波束场景下波束失败检测的方案。图5所示的方法中，当接入网设备通过TCI指示公共波束时，终端设备可以确定用于波束失败检测的下行接收波束，以进行波束失败检测。
可选的，图5所示的方法还包括：当TCI包括第一上行参考信号的信息，终端设备可以基于第一上行参考信号的信息确定公共波束。例如，终端设备通过所述第一上行参考信号对应的空间滤波传输器发送多个上行信道，和/或，通过所述第一上行参考信号对应的空间滤波传输器接收多个下行信道。
当TCI包括第一下行参考信号的信息，终端设备可以基于第一上行参考信号的信息确定公共波束。例如，通过接收所述第一下行参考信号的空间滤波传输器接收多个下行信道，和/或，通过接收所述第一下行参考信号的空间滤波传输器发送多个上行信道。
可选的，图5所示的方法还包括：终端设备确定发生波束失败后，还可以根据候选波束(例如，q_1或candidate beam中的波束)确定新波束(例如，q_new)，后续可以通过q_new与接入网设备进行通信。终端设备还可以将q_new作为公共波束，将当前激活的第一TCI更新为q_new关联的TCI(以下简称为第三TCI)，将当前的公共TCI(即第一TCI)去激活，激活第三TCI作为新的公共TCI。终端设备可以根据第三TCI确定公共波束，例如，上行公共波束、下行公共波束或上下行公共波束。
具体地，包括以下步骤a1～步骤a5：
步骤a1、终端设备根据所述第一下行参考信号测量结果或所述第一上行参考信号的测量结果确定发生波束失败，对候选波束关联的下行参考信号进行测量。
具体地，当测量结果持续低于阈值，则判断发生波束失败，终端设备无法通过当前激活的第一TCI指示的公共波束接收到接入网设备发送的下行信号。终端设备需要 向对候选波束关联的下行参考信号，以便通过合适的空间滤波传输器发送波束失败恢复请求。
例如，终端设备尝试使用不同的空间滤波传输器接收候选波束关联的下行参考信号(以下简称为下行参考信号x)，测量使用不同的空间滤波传输器下行参考信号的接收质量值。
步骤a2、终端设备根据所述候选波束关联的下行参考信号的测量结果确定发送波束失败恢复请求的第一空间滤波传输器的参数。
具体地，终端设备在步骤a1对不同的空间滤波传输器下接收的下行参考信号进行测量，确定最佳测量结果(即最高的接收质量值)对应的空间滤波传输器，例如，本申请实施例所述的第一空间滤波传输器。终端设备还可以通过该空间滤波传输器发送波束失败恢复请求。第一空间滤波传输器对应q_new，终端设备后续可以通过q_new与基站进行通信。
步骤a3、终端设备通过所述第一空间滤波传输器向所述接入网设备发送所述波束失败恢复请求。
具体地，终端设备可以使用与接收下行参考信号x的相同天线端口和/或相同天线面板的QCL参数来发送波束失败恢复请求。
步骤a4、终端设备通过所述第一空间滤波传输器接收来自所述接入网设备的波束失败恢复请求响应。
步骤a5、终端设备通过所述第一空间滤波传输器发送多个上行信道，和/或，通过第一空间滤波传输器接收多个下行信道。
具体地，当通过所述第一空间滤波传输器接收到来自所述接入网设备的波束失败恢复请求响应，终端设备可以明确接入网设备已经获知当前激活的第一TCI失效，且接入网设备允许激活q_new关联的TCI，则终端设备根据q_new关联的TCI确定公共波束。例如，可以使用所述第一空间滤波传输器发送多个上行信道，和/或，通过第一空间滤波传输器接收多个下行信道。
示例的，终端设备将激活的第一TCI更新为q_new关联的第三TCI，第三TCI可以作为下行公共TCI，即q_new可以作为下行公共波束。
或者，第三TCI可以作为下行控制信道公共TCI，即q_new作为下行控制信道的公共波束。
或者，终端将q_new作为下行公共波束，将发送PRACH的波束作为上行公共波束。
可选的，图5所示的方法还包括，终端设备确定发生波束失败后，接收接入网设备更新的公共TCI(例如，本申请实施例所述的第二TCI)，将当前激活的第一TSI更新为第二TCI，终端设备可以根据第二TCI确定公共波束，例如，上行公共波束、下行公共波束或上下行公共波束。
具体地，包括以下步骤b1～步骤b4：
步骤b1～步骤b3同前文所述的步骤a1～步骤a3，在此不做赘述。
步骤b4、终端设备通过所述第一空间滤波传输器接收来自所述接入网设备的波束失败恢复请求响应，所述波束失败恢复请求响应包括第二TCI。
其中，第二TCI为公共TCI，可以指示公共波束。例如，所述第二TCI包括第二上行参考信号的信息和/或第二下行参考信号的信息；所述第二上行参考信号对应的空间滤波传输器用于发送多个上行信道，所述第二下行参考信号与多个下行信道的DMRS满足QCL关系。
具体地，当通过所述第一空间滤波传输器接收到来自所述接入网设备的波束失败恢复请求响应，终端设备可以明确接入网设备已经获知当前激活的第一TCI失效，且接入网设备允许激活第二TCI，则终端设备根据第二TCI确定公共波束。
具体地，当第二TCI包括第二上行参考信号的信息，终端设备通过所述第二上行参考信号对应的空间滤波传输器发送多个上行信道，和/或，通过所述第二上行参考信号对应的空间滤波传输器接收多个下行信道。
当第二TCI包括第二下行参考信号的信息，终端设备可以通过接收所述第二下行参考信号的空间滤波传输器接收多个下行信道，和/或，通过接收所述第二下行参考信号的空间滤波传输器发送多个上行信道。
一种可能的实现方式中，第二TCI指示上行公共波束，终端设备可以采用该公共波束发送PUCCH、PUSCH，采用q_new接收PDCCH。
例如，第二TCI包括第二上行参考信号的信息，终端设备可以通过发送第二上行参考信号的空间滤波传输器发送PUCCH和PUSCH，采用q_new关联的空间滤波传输器接收PDCCH。
具体地，终端设备假设接收PDCCH所采用的波束/参数/空间滤波传输器与接收q_new所关联的参考信号所采用的天线端口QCL参数相同和/或相同天线面板QCL参数相同。
另一种可能的实现方式中，第二TCI指示下行公共波束。终端设备可以采用该公共波束接收PDCCH、PDSCH，采用发送PRACH的波束发送PUCCH。
例如，第二TCI包括第二下行参考信号的信息，终端设备可以通过接收第二下行参考信号的空间滤波传输器接收PDCCH和PDSCH，通过发送PRACH的空间滤波传输器发送PUCCH。
另一种可能的实现方式中，第二TCI指示上下行公共波束，所述上下行公共波束可以用于接收PDCCH和PDSCH，发送PUCCH和PUSCH。

或者，第二TCI包括第二下行参考信号的信息，终端设备可以使用接收所述第二下行参考信号的空间滤波传输器发送PUCCH和/或PUSCH，使用接收所述第二下行参考信号的空间滤波传输器接收PDCCH和/或PDSCH。
另一种可能的实现方式中，公共波束只用于部分信道。终端设备根据TCI传输支持公共波束的信道，对于不支持公共波束的信道，终端设备采用接收q_new所指示参考信号的接收参数(该接收参数用于接收q_new所指示的参考信号)，接收其中的下行信道，或者，采用q_new所指示的参考信号关联的空间滤波传输器接收其中的下行信道。或者，终端设备接收接收下行信道可以采用与接收q_new参考信号相同的天线 端口和/或天线面板的QCL参数。终端设备采用PRACH的发送波束发送其中的上行信道，或者，采用PRACH的发送波束关联的空间滤波传输器发送其中的上行信道。
