Description

数据接收、数据发送方法以及装置 技术领域
本申请实施例涉及通信技术领域。
背景技术
3GPP标准化组织在版本17(release，Rel-17)的标准化过程中，对统一的(unified)传输配置指示(transmission configuration indication，TCI)进行了标准化相关的工作。其中，Rel-17中的unified TCI主要是针对单个TRP或者称为单TRP(single transmission and reception point，sTRP)场景进行设计的。
随着标准化工作的推进，多个TRP或者称为多TRP(multiple transmission and reception point，mTRP或者multi-TRP)成为5G NR系统的重要场景，通过基于mTRP的传输，可以达到提高吞吐量或提高可靠性的目的。
在以往的标准化工作中，在Rel-16中，对基于mTRP的物理下行共享信道(Physical Downlink Shared Channel，PDSCH)的传输进行了标准化；在Rel-17中，对基于mTRP的物理下行控制信道(Physical Downlink Control Channel，PDCCH)、物理上行共享信道(Physical Uplink Shared Channel，PUSCH)、物理上行控制信道(Physical Uplink Control Channel，PUCCH)传输进行了标准化。其中，mTRP传输包括基于单DCI(single Downlink Control Information，sDCI)的mTRP传输和基于多DCI(multiple DCI，mDCI)的mTRP传输。
应该注意，上面对技术背景的介绍只是为了方便对本申请的技术方案进行清楚、完整的说明，并方便本领域技术人员的理解而阐述的，不能仅仅因为这些方案在本申请的背景技术部分进行了阐述而认为上述技术方案为本领域技术人员所公知。
发明内容
在Rel-17 unified TCI针对sTRP(single transmission and reception point)的场景下，网络设备使用无线资源控制(Radio Resource Control，RRC)信令为终端设备配置M(M≥1)个(组)TCI状态(TCI state)，使用介质访问控制(MAC)控制元素(CE)在M个TCI状态中激活N(1≤N≤M)个(组)TCI状态，使用DCI在N个 (组)TCI状态中指示L(1≤L≤N)个(组)TCI状态。其中，DCI格式1_1或DCI格式1_2的传输配置指示(TCI，transmission configuration indication)字段(下文会称之为“TCI字段”)指示一个或多个TCI状态(TCI state)，此外，为表述方便，也会将“DCI的TCI字段指示的”简称为“DCI指示的”)，每组TCI state中包括一个或多个TCI state。
一个TCI状态(简称TCI)可以包括或对应一个或两个源参考信号(source RS,source Reference Signal)。源参考信号可以为下行接收提供准共址(QCL，Quasi Co-Location)信息，称为下行源参考信号。源参考信号可以为上行发送空间滤波器(UL TX spatial filter，uplink transmission spatial filter)提供参考，称为上行源参考信号。源参考信号可以为目的信道/信号提供波束信息。例如，终端设备用于接收目的信道/信号的波束与用于接收下行源参考信号的波束相同。又例如，终端设备用于发送目的信道/信号的波束与用于发送上行源参考信号的波束相同。又例如，终端设备用于发送目的信道/信号的波束与用于接收下行源参考信号的波束具有互易性，即使用方向相反的波束。
因此，对TCI状态(TCI state)的指示或更新实际上也包括了对终端设备所用波束的指示或更新。TCI状态包括联合TCI状态(joint DL/UL TCI state)和单独TCI状态(separate DL/UL TCI state)，其中，单独TCI状态包括：单独下行TCI状态(separate DLTCI state)和单独上行TCI状态(separate UL TCI state)。本申请的“联合”或“单独”都是指的是上下行联合或上下行单独。单独TCI state可分为单独下行TCI state和单独上行TCI state，后文提到的下行TCI state或第一/第二下行TCI state属于单独TCI state，后文提到的上行TCI state或第一/第二上行TCI state也属于单独TCI state。
下行TCI状态包含的源参考信号是下行源参考信号，上行TCI状态包含的源参考信号是上行源参考信号，联合TCI状态包含的源参考信号既是下行源参考信号，又是上行源参考信号。联合TCI状态同时作用于下行波束(接收波束)和上行波束(发送波束)，换句话说，下行波束和上行波束使用的是同一个波束，但波束方向相反，即上下行波束之间存在互易性。下行TCI状态仅作用于下行波束。上行TCI状态仅作用于上行波束。上行波束也称为上行发送空间滤波器。TCI字段可以指示联合TCI状态(joint DL/UL TCI)，或者TCI字段可以指示下行TCI状态和/或上行TCI状态(separate DL/UL TCI)，这两种模式可以通过RRC信令进行配置。对于Rel-17的 unified TCI，一个TCI字段指示一个联合TCI状态，或者指示一个下行TCI状态，或者指示一个上行TCI状态，或者指示一个下行TCI状态和一个上行TCI状态。
NR系统中用高层参数“unifiedTCI-StateType”来配置是使用联合TCI state还是单独TCI state。相应的DCI的TCI字段指示(后文的表述可以替换为“DCI指示的TCI state”)的是联合TCI state还是单独TCI sate会取决于高层参数“unifiedTCI-StateType”：在该“unifiedTCI-StateType”参数取值为‘joint’的情况下，DCI指示的是一个或多个联合TCI state(Rel-17中最多指示1个joint TCI state，Rel-18最多可指示2个joint TCI state)；在该“unifiedTCI-StateType”参数取值为‘separate’的情况下，DCI指示的是一个或多个单独TCI state。
多TRP(mTRP，multiple transmission and reception point)是5G NR系统的重要场景，通过基于mTRP的传输，可以达到提高吞吐量或提高可靠性的目的。Rel-16对基于mTRP的PDSCH传输进行了标准化，Rel-17对基于mTRP的PDCCH、PUSCH、PUCCH传输进行了标准化。此外，当前Rel-17中的mTRP传输包括基于sDCI(single DCI)的mTRP传输和基于mDCI(multiple DCI)的mTRP传输。对于基于sDCI的mTRP传输，一个DCI对两个TRP的上下行传输进行调度，更适用于TRP之间的回传(backhaul)比较理想的情况；对于基于mDCI的mTRP传输，两个TRP使用两个DCI分别对各自TRP的上下行传输进行调度，更适用于TRP之间的回传不是很理想的情况。
但是，发明人发现：对于Rel-18的sDCI mTRP场景，网络设备激活以及指示的TCI state与终端设备能够应用的(更新的和/或维持的)TCI state会存在不一致的情况，因此，终端设备如何确定应用的TCI state是需要解决的问题。
针对上述问题的至少之一，本申请实施例提供一种数据接收、数据发送方法以及装置。终端设备在接收第一指示信息以及第二指示信息后确定应用的第一TCI state和/或第二TCI state。由此，终端设备能够明确应用的(更新的和/或维持的)TCI state，从而能够准确地进行上行数据的发送以及下行数据的接收，并且统一了网络设备和终端设备对于用户行为的理解。

以下通过示例对本申请实施例的场景进行说明，但本申请不限于此。
图1是本申请实施例的通信系统的示意图，示意性说明了以终端设备和网络设备为例的情况，如图1所示，通信系统100可以包括第一TRP 101、第二TRP 102和终端设备103。其中，第一TRP 101和第二TRP 102可以为网络设备。为简单起见，图 1仅以两个网络设备和一个终端设备之间的PDSCH信道为例进行说明，但本申请实施例不限于此。
在本申请实施例中，第一TRP 101、第二TRP 102和终端设备103之间可以进行现有的业务或者未来可实施的业务发送。例如，这些业务可以包括但不限于：增强的移动宽带(eMBB，enhanced Mobile Broadband)、大规模机器类型通信(mMTC，massive Machine Type Communication)和高可靠低时延通信(URLLC，Ultra-Reliable and Low-Latency Communication)，等等。
Rel-16对基于mTRP的PDSCH传输进行了标准化，Rel-17对基于mTRP的PDCCH、PUSCH、PUCCH传输进行了标准化。mTRP传输包括基于sDCI(single DCI)的mTRP传输和基于mDCI(multiple DCI)的mTRP传输。对于基于sDCI的mTRP传输，一个DCI对两个TRP的上下行传输进行调度，更适用于TRP之间的回传(backhaul)比较理想的情况。对于基于mDCI的mTRP传输，两个TRP使用两个DCI分别对各自TRP的上下行传输进行调度，更适用于TRP之间的回传不是很理想的情况。
图1以终端设备103在mTRP场景下进行PDSCH接收为例。例如，终端设备接收来自第一TRP 101、第二TRP 102的两路PDSCH，可以以空分的形式，可以以时分的形式，也可以以频分的形式。终端分别根据与第一TRP 101对应的TCI state 1和与第二TRP 102对应的TCI state 2提供的准共址信息接收两路PDSCH。
如图1所示，以时分的形式为例，终端设备103以PDSCH重复(PDSCH repetition)的方式接收PDSCH。例如，在第一时隙接收第一TRP 101发送的PDSCH，在第二时隙接收第二TRP 102发送的PDSCH，以此类推。
Rel-17引入了unified TCI，下行TCI状态或联合TCI状态可以至少为UE专用的PDSCH接收和/或UE专用的PDCCH接收提供准共址信息；上行TCI状态或联合TCI state可以至少为UE专用的PUSCH发送和/或UE专用的PUCCH发送提供准共址信息。Rel-17中unified TCI方案适用于sTRP场景，该场景中只有上行链路和下行链路这2条传输链路，例如，在MAC CE中激活至少一组TCI state并指示相应的TCI state，然后在DCI的TCI字段中指示使用哪组激活的TCI state。例如，MAC CE最多可激活8组TCI state(后文称之为TCI组)，分别对应到DCI中TCI字段相应的TCI编码点(TCI codepoint)上。每组TCI state有1个或2个TCI state。在“unifiedTCI- StateType”字段取值为‘separate’的情况下，一个TCI组可以有2个TCI state，可分别为上行和下行传输都提供QCL参考；一个TCI组可以只有1个DL TCI state，可为下行传输提供QCL参考；一个TCI组可以只有1个UL TCI state，可为上行传输提供QCL参考。在“unifiedTCI-StateType”字段取值为‘joint’的情况下，一个TCI组只有一个joint TCI state，可一起为上行和下行传输提供QCL参考。
以下对于Rel-17中，对于unified TCI state，终端设备确定应用的TCI state的主要步骤举例说明：
-RRC配置
当RRC参数unifiedTCI-StateType取值为‘joint’时，RRC层会在dl-OrJointTCI-StateList列表中配置最多128个TCI state，这些TCI state为joint TCI state，可同时为下行和上行提供QCL信息；当RRC参数unifiedTCI-StateType取值为’separate’时，RRC层会在dl-OrJointTCI-StateList列表中配置最多128个TCI state，这些TCI state为separate DL TCI state，可为下行接收提供QCL信息。与此同时，RRC层还会在ul-TCI-ToAddModList列表中配置最多64个TCI state，这些TCI state为separate UL TCI state，可为上行发送提供QCL信息。
对于一些载波聚合(CA，Carrier Aggregation)的情况，一个频带内多个分量载波(CC，Component Carrier)使用的波束无明显差异，可以共用同一个波束信息。为了节省波束指示信令，不需要为每个CC都配置独立的TCI state信息(如分别配置独立的dl-OrJointTCI-StateList和/或ul-TCI-ToAddModList)，可以使用一个共同的信令，指示一个CC列表内的多个CC的TCI state信息。
Rel-17中支持配置最多4个CC列表(simultaneousU-TCI-UpdateList1～simultaneousU-TCI-UpdateList4)，每个列表中指定一个参考CC(reference CC)，只为参考CC配置TCI state信息，列表中其他CC不再单独配置，而是跟参考CC共用TCI state信息，即一个CC列表中所有CC的TCI state配置信息是同时更新的。RRC参数中配置的4个CC列表如下表1(TS 38.331 6.3.2节)所示：

为下行或联合(DL/joint)情况配置的reference CC由RRC参数PDSCH-Config中的unifiedTCI-StateRef指定，如下表2(TS 38.331 6.3.2节)所示。在当前CC没有配置dl-OrJointTCI-StateList(即当CC不是reference CC)的情况下，使用unifiedTCI-StateRef指定的reference CC中配置的dl-OrJointTCI-StateList。
表2：RRC参数为DL/joint情况配置的unifiedTCI-StateRef
为上行(UL)情况配置的reference CC由RRC参数BWP-UplinkDedicated中的unifiedTCI-StateRef指定，如表3(TS 38.331 6.3.2节)所示。在当前CC没有配置ul-TCI-StateList(即当CC不是reference CC)的情况下，使用unifiedTCI-StateRef指定的reference CC中配置的ul-TCI-StateList。例如，表3中的“unifiedTCI-StateRef”相关参数是reference CC在参数配置中的ServCelIndex和其他参数的组合(ServingCellAndBWP-Id)：
表3：RRC参数为UL情况配置的unifiedTCI-StateRef

-MAC-CE激活/去激活
通过MAC-CE选择激活最多8组TCI-State，分别对应DCI中的TCI字段能指示的8个TCI codepoint。Rel-17中会为每个TCI codepoint配置1个或2个TCI state，可为单个TRP到UE的上行和/或下行链路提供QCL信息。
图2是本申请实施方式MAC CE的第一格式的一示例图。例如，该第一格式是版本17中的媒体接入控制控制元素(MAC CE)格式。
Rel-17中激活/去激活unified TCI state的MAC CE格式如图2所示。图中Pi(i＝1,2,…,8)指示激活/去激活第i组TCI state；每组TCI state具有1个或者2个TCI state，例如，Pi取值“0”表示对应的字节(Octet，OCT)处有1个TCI state，例如，可以对应1个“下行/联合TCI state”或者1个“上行TCI state”，Pi取值“1”表示有2个TCI state(即有1个DL TCI state和1个UL TCI state)，例如Pi与对应的字节Oct的确定方式可以参照现有技术，本申请对此不进行限制。例如，图2中的D/U字段表示其所在行的TCI state ID对应的TCI state是“下行/联合TCI state”还是“上行TCI state”，例如，在“D/U”取值为“1”的情况下，其指示其所在行的TCI state ID对应的TCI state是“下行/联合TCI state”；在“D/U”取值为“0”的情况下，其指示其所在行的TCI state ID对应的TCI state是“上行TCI state”。
例如，“Pi(i＝1,2,…,8)指示激活/去激活第i组TCI state”还可以表述为“Pi(i＝1,2,…,8)表示TCI codepoint i有1个还是2个TCI state”，其中，“TCI codepoint”是DCI中的TCI字段指示的内容，例如，MAC CE中最多可以激活8个TCI组(由图2中的P1-P8进行指示)，与之对应的，DCI格式1_1或DCI格式1_2的TCI字段位宽3bit，共有8个可能的编码值：000,001,010,011,100,101,110,111，其中，每个编码值都可叫一个TCI codepoint，8个编码值就有8个TCI codepoint，依次为TCI codepoint 1,TCI codepoint 2…,TCI codepoint 8，跟MAC CE中8个TCI组一一对应，例如“TCI codepoint 1”指示的TCI state即对应P1指示的1个TCI state或者2个TCI state。
-DCI指示
DCI格式1_1/1_2的TCI字段(Transmission Configuration Indication field)选择MAC-CE里其中一组激活的TCI state，用于相应信道/信号的接收或发送。TCI字段的一种取值对应1个TCI codepoint，目前TCI字段最大宽度3bit，可最多指示23＝8个TCI codepoint。
由于Rel-17中的CC均是工作在sTRP下的，也可表述为Rel-17中reference CC是sTRP CC，因此，终端设备根据DCI指示的TCI state能够直接确定应用的TCI state。
发明人发现：Rel-17unified TCI仅适用于sTRP场景。考虑到mTRP的重要性，有必要为mTRP场景设计相应的unified TCI机制。3GPP将在Rel-18对mTRP的unified TCI进行标准化。目前，mTRP的unified TCI已经被确定为Rel-18的立项内容之一，Rel-18的标准化工作正在进行。
图3A是本申请实施例mTRP场景下的上下行链路的一个示例图；图3B是本申请实施例mTRP场景下的上下行链路的一个示例图。
在Rel-18中mTRP场景下的unified TCI方案中，对UE 103来说，对应每个TRP都有下行和上行链路，UE跟2个TRP之间一共有4条链路，例如，UE 103到第一TRP 101之间分别具有下行链路(后文称之为第一下行链路)、上行链路(后文称之为第一上行链路)、UE103到第一TRP 102之间分别具有下行链路(后文称之为第二下行链路)、上行链路(后文称之为第二上行链路)以便为其对应链路的传输提供QCL参考。
mTRP传输中，高层参数unifiedTCI-StateType取值为‘separate’时，如图3A所示，上述四条链路对应的TCI state为{第一下行TCI state(DL TCI state 1)、第一上行TCI state(UL TCI state 1)、第二下行TCI state(DL TCI state 2)、第二上行TCI state(UL TCI state 2)}，可分别为第一下行链路、第一上行链路、第二下行链路、第二上行链路提供QCL参考。在该场景下，DCI中的一个TCI codepoint需要对应4个激活的TCI state，或对应这4个激活TCI state中的一部分。
mTRP传输中，高层参数unifiedTCI-StateType取值为‘joint’时，如图3B所示，上述四条链路对应的TCI state为{第一联合TCI state(Joint TCI state 1)，第二联合TCI state(Joint TCI state 2)}，其中，第一联合TCI state可以对第一下行链路和第一上行链路提供QCL参考，第二联合TCI state可以对第二下行链路和第二上行链路提供QCL参考。
但是，在Rel-18中，在一个CC列表中reference CC是sTRP CC的情况下，MAC CE以及DCI只指示一个TCI state，但是终端设备可能在mTRP CC上接收该MAC CE以及DCI，即终端设备应用2个TCI state；以及，在一个CC列表中reference CC是mTRP CC的情况下，MAC CE以及DCI只指示两个TCI state，但是终端设备可能在sTRP CC上接收该MAC CE以及DCI，即终端设备应用1个TCI state；那么终端设备无法确定应用哪个TCI state。因此，如果仍然使用Rel-17中应用TCI state的方法，终端设备无法确定应用的TCI state。
针对上述问题的至少之一，本申请实施例提供一种数据接收、数据发送方法以及装置。
第一方面的实施例
本申请实施例提供一种数据接收方法，应用在终端设备侧。
图4是本申请实施例的数据接收方法的一示意图，如图4所示，该方法包括：
401，终端设备接收第一指示信息，其中，该第一指示信息指示统一TCI状态(unified TCI state)集合，其中，该统一TCI状态(unified TCI state)集合包含第一TCI state和/或第二TCI state；
402，终端设备接收第二指示信息，其中，该第二指示信息指示该统一TCI状态(unified TCI state)集合中的该第一TCI state和/或该第二TCI state；
403，终端设备在该统一TCI状态(unified TCI state)集合包含该第一TCI state或该第二TCI state的情况下，根据该第二指示信息确定应用的该第一TCI state和该第二TCI state；或者，在该统一TCI状态(unified TCI state)集合包含该第一TCI state和该第二TCI state的情况下，根据该第二指示信息确定应用的该第一TCI state或所该第二TCI state。
由此，终端设备在接收第一指示信息以及第二指示信息后确定应用的第一TCI state和/或第二TCI state。由此，终端设备能够明确应用的(更新的和/或维持的)TCI state，从而能够准确地进行上行数据的发送以及下行数据的接收，并且统一了网络设备和终端设备对于用户行为的理解。
值得注意的是，以上附图4仅对本申请实施例进行了示意性说明，以终端设备为例，但本申请不限于此。例如可以适当地调整各个操作之间的执行顺序，此外还可以 增加其他的一些操作或者减少其中的某些操作，此外，还可以调整上述操作的对象。本领域的技术人员可以根据上述内容进行适当地变型，而不仅限于上述附图4的记载。
在一些实施方式中，术语例如，“小区(cell)”可以被等价替换为“载波(carrier)”或“分量载波(component carrier)”；上述仅为示例性说明，本申请实施例不限于此。
在一些实施方式中，“指示统一TCI状态(unified TCI state)集合”的表述还可以替换为“激活/去激活统一TCI状态(unified TCI state)集合”；在一些实施方式中，术语“PUSCH”、“PUSCH传输”、“PUSCH发送”可以互相替换；术语“PDSCH”、“PDSCH传输”、“PDSCH发送”可以互相替换；“DL TCI state”或“UL TCI state”可以通过“joint DL/UL TCI state”指示，也可以通过“separate DL/UL TCI state”指示；“DL TCI state”可以是“separate DL TCI state”，也可以是“joint TCI state”；“UL TCI state”可以是“separate UL TCI state”，也可以是“joint TCI state”；上述仅为示例性说明，本申请实施例不限于此。
图5是本申请实施例mTRP相关参数的关联关系的一示意图。对于mTRP，以两个TRP为例，终端设备向两个TRP进行下行传输(DL transmission)，例如包括下行数据传输(可替换为“发送PDSCH”、发送“DL-SCH”等)以及包括下行控制信息传输(可替换为“发送PDCCH”、发送“DCI”等)。图5对此进行了示意性说明。以接收PDSCH为例，图5对TCI state、下行传输、TRP的关联关系进行了示意；对于一个TRP，其与一个TCI state、一个下行传输之间相互关联；例如，如图5所示，第一TCI state对应(等价于)第一TRP；第二TCI state对应(等价于)第二TRP。
在一些实施方式中，第一TCI state包含以下至少之一：第一下行TCI state，第一上行TCI state，第一联合TCI state；所述第二TCI stat包含以下至少之一：第二下行TCI state，第二上行TCI state，第二联合TCI state。

例如，上述上行TCI state、下行TCI state、联合TCI state可以参见前述部分的介绍，在此不做重复说明。
在一些实施方式中，第一指示信息通过MAC CE承载；该第二指示信息通过DCI承载；该MAC CE是第一格式或者是第二格式。在一些实施方式中，该第一格式是版本17中的MAC CE格式；该第二格式是版本18中的MAC CE格式。
例如，第二指示信息通过DCI格式1_1或DCI格式1_2的传输配置指示(TCI，transmission configuration indication)字段指示一个或多个TCI状态(TCI state)，此外，DCI格式1_1或DCI格式1_2可以调度下行数据，称为DCI format 1_1/1_2 with DL assignment，也可以不调度下行数据，称为DCI format 1_1/1_2 without DL assignment；本申请对此不进行限制。
例如，第一指示信息是图2所示的第一格式(版本17(Rel-17)的MAC CE格式)；也可以是第二格式(版本18(Rel-18)的MAC CE格式(图2未示出)，对于第二格式的具体内容本申请不限制其具体的格式内容。
例如，第一指示信息中指示统一TCI状态(unified TCI state)集合，其中，该统一TCI状态(unified TCI state)集合可以只包含第一TCI state(对应第一TRP)，也可以只包含第二TCI state(对应第二TRP)，也可以包含第一TCI state和第二TCI state(对应第一TRP和第二TRP)；进而第二指示信息根据统一TCI状态(unified TCI state)集合包含的TCI state，指示应用的第一TCI state和/或第二TCI state；在第二指示信息是Rel-17 MAC CE格式的情况下，第二指示信心仅能够指示包含第一TCI state的统一TCI状态(unified TCI state)集合(指示单TRP下的TCI state)。
在一些实施方式中，第一指示信息指示第一分量载波(CC)的统一TCI状态(unified TCI state)集合；终端设备在第二分量载波(CC)上确定应用的第一TCI state和/或第二TCI state。
在一些实施方式中，第一分量载波(CC)是参考分量载波(CC)，第二分量载波(CC)与第一分量载波(CC)相同或者不同。在一些实施方式中，在第二分量载波 (CC)与所述第一分量载波(CC)不同的情况下，第二分量载波(CC)与所述第一分量载波(CC)属于同一第一列表；所述第一列表包括同时更新TCI更新列表1(simultaneousU-TCI-UpdateList1)至同时更新TCI更新列表4(simultaneousU-TCI-UpdateList4)。
例如，该同时更新TCI更新列表1(simultaneousU-TCI-UpdateList1)至同时更新TCI更新列表4(simultaneousU-TCI-UpdateList4)的具体内容可以参见现有技术本；此外，对于“参考分量载波(CC)”和与“参考分量载波(CC)”属于同时更新TCI更新列表1(simultaneousU-TCI-UpdateList1)至同时更新TCI更新列表4(simultaneousU-TCI-UpdateList4)的其他分量载波的具体内容，也可以参见现有技术，本申请对此不进行限制。
在一些实施方式中，在第一指示信息是Rel-18 MAC CE格式的情况下，在第一指示信息指示的统一TCI状态(unified TCI state)集合仅包含了第一TCI state或者仅包含第二TCI state的情况下，对应的第一分量载波(CC)是sTRP CC，也对应，reference CC是sTRP CC；或者，在第一指示信息是Rel-17 MAC CE格式的情况下，在第一指示信息指示的统一TCI状态(unified TCI state)集合仅可以包含第一TCI state，对应的第一分量载波(CC)是sTRP CC，也对应，reference CC是sTRP CC；
例如，终端设备收到的TCI激活/去激活MAC-CE信令(第一指示信息)是Rel-18格式，以及对每一个TCI codepoint都只激活了第一DL/joint TCI state，且对应每一个TCI codepoint都只激活了第一UL TCI state；或者对每一个TCI codepoint都只激活了第二DL/joint TCI state，且对应每一个TCI codepoint都只激活了第二UL TCI state，该第一分量载波(CC)即为sTRP CC；
例如，终端设备收到的TCI激活/去激活MAC-CE信令(第一指示信息)是Rel-17格式，该第一分量载波(CC)即为sTRP CC。
在一些实施方式中，在第一指示信息是Rel-18 MAC CE格式的情况下，在第一指示信息指示的统一TCI状态(unified TCI state)集合中包含了第一TCI state和第二TCI state的情况下，该第一分量载波(CC)即为mTRP CC，也对应，reference CC是mTRP CC。
例如，终端收到的TCI激活/去激活MAC-CE信令(第一指示信息)是Rel-18格式，以及至少有1个TCI codepoint对应激活了2个DL/joint TCI state和/或至少有1 个TCI codepoint对应激活了2个UL TCI state的情况下，该第一分量载波(CC)即为mTRP CC，也对应，reference CC是mTRP CC。
在一些实施方式中，上述“在统一TCI状态(unified TCI state)集合包含第一TCI state或第二TCI state的情况下”即对应第一分量载波(CC)是sTRP CC的情况；上述“在统一TCI状态(unified TCI state)集合包含第一TCI state和第二TCI state的情况下”即对应第一分量载波(CC)是mTRP CC的情况。
在一些实施方式，上述“终端设备在第二分量载波(CC)上确定应用第一TCI state或第二TCI state”与“第二分量载波(CC)是sTRP CC对应”；“终端设备在第二分量载波(CC)上确定应用第一TCI state和第二TCI state”与“第二分量载波(CC)是mTRP CC对应”。
以上对于确定第一分量载波(CC)/第二分量载波(CC)是sTRP CC还是mTRP CC的情况进行举例说明，以下对于终端设备如何确定应用的是一个TCI state还是两个TCI state举例说明。
在一些实施方式中，“确定应用的TCI state”是指终端设备接收第二指示信息后，“更新TCI state”和/或“不更新TCI state”(“维持TCI state不变”)；例如，在确定应用一个TCI state后，“确定应用的TCI state”可以指“更新第一TCI state”或者“更新第二TCI state”；在确定应用第一TCI state和第二TCI state后，“确定应用的TCI state”是指“更新第一TCI state，维持第二TCI state不变”或者是指“更新第二TCI state，维持第一TCI state不变”；在一些实施方式中，“更新第一TCI state”包括“更新第一DL/joint TCI state和更新第一UL TCI state”或“更新第一DL/joint TCI state，以及维持第一UL TCI state不变”或“更新第一UL TCI state，以及维持第一DL/joint TCI state不变”等；在一些实施方式中，“更新第二TCI state”包括“更新第二DL/joint TCI state和更新第二UL TCI state”或“更新第二DL/joint TCI state，以及维持第二UL TCI state不变”或“更新第二UL TCI state，以及维持第二DL/joint TCI state不变”等；以上仅对“确定应用的TCI state”的含义进行示例性说明，后续将结合具体实施方式进行详细介绍。
在一些实施方式中，终端设备还接收第三指示信息，其中，该第三指示信息指示应用该第一TCI state和该第二TCI state，或者，该第三指示信息指示应用该第一TCI state或该第二TCI state。在一些实施方式中，第三指示信息通过RRC信令承载。
可替换的，“该第三指示信息指示应用该第一TCI state和该第二TCI state”即对应终端设备工作在mTRP CC下，即对应第二分量载波(CC)是mTRP CC；“该第三指示信息指示应用该第一TCI state或该第二TCI state”即对应终端设备工作在sTRP CC下，即对应第二分量载波(CC)是sTRP CC，本申请对于上述表述不进行限制。
以下对于第三指示信息的具体内容举例说明：
在一些实施方式中，在该第三指示信息配置了第一参数和/或第二参数的情况下，该第三指示信息指示应用该第一TCI state和该第二TCI state；在该第三指示信息未配置第一参数和/或第二参数的情况下，该第三指示信息指示应用该第一TCI state或该第二TCI state。
例如，该第一参数是RRC信令中“RepetitionSchemeConfig”中的相关参数；和/或，例如，该第一参数是RRC信令中“repetitionNumber”中的相关参数。
例如，在RRC信令配置了“RepetitionSchemeConfig”中的参数‘fdm-TDM’中的参数“repetitionScheme”的值为‘fdmSchemeA’或‘fdmSchemeB’或‘tdmSchemeA’，和/或，在RRC信令配置了参数‘repetitionNumber’的情况下，该第三指示信息指示应用该第一TCI state和该第二TCI state，可选的，表示终端设备工作在mTRP CC上，即第二分量载波是mTRP CC；
例如，在RRC信令没有配置“RepetitionSchemeConfig”中的参数‘fdm-TDM’中的参数“repetitionScheme”的值，并且，在RRC信令没有配置参数‘repetitionNumber’的情况下，该第三指示信息指示应用该第一TCI state或该第二TCI state，可选的，表示终端设备工作在sTRP CC上，即第二分量载波是sTRP CC。
例如，关于上述“RepetitionSchemeConfig”，“repetitionScheme”，‘fdmSchemeA’，‘fdmSchemeB’，‘tdmSchemeA’，“RepetitionSchemeConfig”，‘repetitionNumber’等参数的具体内容，请参见现有技术，本申请对此不进行限制。
例如，该第二参数是RRC信令中“ControlResourceSet”中的相关参数。
例如，在RRC信令配置了“ControlResourceSet”中的参数“followUnifiedTCI-State”的值为‘enabled’的情况下，该第三指示信息指示应用该第一TCI state和该第二TCI state，可选的，表示终端设备工作在mTRP CC上，即第二分量载波是mTRP CC；
例如，在RRC信令未配置“ControlResourceSet”中的参数“followUnifiedTCI-State”的情况下，该第三指示信息指示应用该第一TCI state或该第二TCI state，可选的，表 示终端设备工作在sTRP CC上，即第二分量载波是sTRP CC。
例如，关于上述“ControlResourceSet”，“followUnifiedTCI-State”等参数的具体内容，请参见现有技术，本申请对此不进行限制。
在一些实施方式中，在该第三指示信息配置的第三参数取第一值的情况下，该第三指示信息指示应用该第一TCI state和该第二TCI state；在该第三指示信息配置的第三参数取第二值的情况下，该第三指示信息指示应用该第一TCI state或该第二TCI state。
例如，该第三参数是RRC信令中新引入的参数“trp-Mode”，该“trp-Mode”可以取第一值‘mtrp’；也可以取第二值‘strp’；如表4所示，其为参数“trp-Mode”的一示例：
表4
例如参数“trp-Mode”对应表4中的“trp-Mode-r18”，例如，在该“trp-Mode”取第一值‘mtrp’的情况下，该第三指示信息指示应用该第一TCI state和该第二TCI state，可选的，表示终端设备工作在mTRP CC上，即第二分量载波是mTRP CC；例如，在该“trp-Mode”取第一值‘strp’的情况下，该第三指示信息指示应用该第一TCI state或该第二TCI state，可选的，表示终端设备工作在sTRP CC上，即第二分量载波是sTRP CC。
在明确了第一分量载波(CC)以及第二分量载波(CC)是sTRP CC还是mTRP CC的情况下，以下对于如何具体确定应用的第一TCI state和/或第二TCI state进行举例说明：
在一些实施方式中，以预定义的方式结合第二指示信息确认应用的第一TCI state和/或第二TCI state，以下分别举例说明：
在一些实施方式中，在第三指示信息指示应用第一TCI state和第二TCI state以及该统一TCI状态(unified TCI state)集合包含该第一TCI state或该第二TCI state情况下，在该第二指示信息指示该第一TCI state或者该第二TCI state的情况下，根 据指示的该第一TCI state或者指示的该第二TCI state确定更新应用的该第一TCI state，以及维持应用的该第二TCI state不变；或者在该第二指示信息指示该第一TCI state或者该第二TCI state的情况下，根据指示的该第一TCI state或者指示的该第二TCI state确定更新应用的该第二TCI state，以及维持应用的该第一TCI state不变。
例如，在根据上述实施方式确定了第三指示信息指示应用第一TCI state和第二TCI state(终端设备工作在mTRP CC上)以及在根据上述实施方式确定在统一TCI状态(unified TCI state)集合中仅包含第一TCI state或仅包含第二TCI state的情况下(参考CC是sTRP CC)，在第二指示信息指示该第一TCI state或者该第二TCI state的情况下，预定义终端设备根据指示的第一TCI state或者第二TCI state更新应用的第一TCI state以及维持第二TCI state不变；或者，预定义终端设备根据指示的第一TCI state或者第二TCI state更新应用的第二TCI state以及维持第一TCI state不变。
图6A是本申请实施例确定应用的第一TCI state和/或第二TCI state的一示例图；例如，第一指示信息(MAC CE)中对于8个code point均仅激活了第一TCI state，并且第二指示信息(DCI)指示了一个code point上的第一TCI state，例如该code point上的第一TCI state包含：第一DL/joint TCI state和第一UL TCI state，预定义终端设备更新应用的第一TCI state(包括第一DL/joint TCI state和第一UL TCI state)并且维持第二TCI state(包括第二DL/joint TCI state和第二UL TCI state)不变。可选的，图6A未示出，例如，第一指示信息(MAC CE)中对于8个code point均仅激活了第二TCI state，并且第二指示信息(DCI)指示了一个code point上的第二TCI state，例如该code point上的第二TCI state包含：第二DL/joint TCI state，预定义终端设备更新应用的第一TCI state(用指示的“第二DL/joint TCI state”更新应用的“第一DL/joint TCI state”)，并且维持第二TCI state(包括第二DL/joint TCI state和第二UL TCI state)不变。
图6B是本申请实施例确定应用的第一TCI state和/或第二TCI state的另一示例图；例如，第一指示信息(MAC CE)中对于8个code point均仅激活了第一TCI state，并且第二指示信息(DCI)指示了一个code point上的第一TCI state，例如该code point上的第一TCI state包含：第一DL/joint TCI state和第一UL TCI state，预定义终端设备更新应用的第二TCI state(用指示的“第一DL/joint TCI state”和“第一UL TCI state”更新应用的“第二DL/joint TCI state”和“第二UL TCI state”)并且维持第一 TCI state(包括第一DL/joint TCI state和第一UL TCI state)不变。
在一些实施方式中，在第三指示信息指示应用该第一TCI state或该第二TCI state以及该统一TCI状态(unified TCI state)集合包含该第一TCI state和该第二TCI state的情况下，在该第二指示信息指示该第一TCI state和该第二TCI state的情况下，根据指示的该第一TCI state确定更新应用的该第一TCI state；或者根据指示的该第二TCI state确定更新应用的该第一TCI state。
