Description

信号发送和接收装置以及方法 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主要针对sTRP(single transmission and reception point)场景进行设计。
随着标准化工作的推进，多TRP(mTRP，multiple transmission and reception point)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
但是，发明人发现：Rel-17中的unified 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。
在Rel-17unified 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(RRC)信令为终端设备配置M(M≥1)个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TCI状态，使用下行控制信息(DCI)在N个TCI状态中指示L(1≤L≤N)个TCI状态。
其中，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、下行TCI状态和上行TCI状态。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字段可以指示独立TCI状态(separate DL/UL TCI)，即指示下行TCI状态和/或上行TCI状态。TCI字段指示的是联合TCI状态还是独立TCI状态由RRC信令进行配置。
对于Rel-17的unified TCI，对于联合TCI状态，一个TCI字段指示一个联合TCI状态，对于独立TCI状态，一个TCI字段指示一个下行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。
对于mTRP的unified TCI，终端设备可以被指示两个上行TCI状态或联合TCI状态。对于具有同时多panel上行传输能力的终端设备，其可以基于两个上行TCI状态或联合TCI状态使用两个panel同时发送。例如，在两个上行TCI状态或联合TCI状态的作用时间内，终端设备进行同时多panel发送。
考虑到移动性、信道状态变化、信道阻塞(blockage)等因素影响，如果终端设备在两个TCI状态的作用时间内总是进行同时多panel上行传输，可能由于无法适应上述快速变化而无法为传输提供吞吐量或可靠性保障，或者，可能由于不必要的多panel发 送而对其他设备造成额外干扰。为解决上述问题，更理想的方式是终端设备能够有更大的自由度来在多种上行传输方案之间灵活切换。
针对上述问题的至少之一，本申请实施例提供一种信号发送和接收装置以及方法。
根据本申请实施例的另一个方面，提供一种信号发送方法，包括：
终端设备接收传输配置指示(TCI)状态指示信息，所述TCI状态指示信息指示第一上行或联合TCI状态和第二上行或联合TCI状态；
所述终端设备接收下行控制信息(DCI)；以及
所述终端设备根据所述下行控制信息指示的上行传输方案，基于所述第一上行或联合TCI状态和/或所述第二上行或联合TCI状态进行上行传输。

第一发送单元，其发送传输配置指示(TCI)状态指示信息，所述TCI状态指示信息指示第一上行或联合TCI状态和第二上行或联合TCI状态；
第二发送单元，其发送下行控制信息(DCI)；以及
接收单元，其接收上行传输；其中，由终端设备根据所述下行控制信息指示的上行传输方案，基于所述第一上行或联合TCI状态和/或所述第二上行或联合TCI状态进行所述上行传输。
根据本申请实施例的另一个方面，提供一种通信系统，包括：
网络设备，其发送传输配置指示(TCI)状态指示信息，所述TCI状态指示信息指示第一上行或联合TCI状态和第二上行或联合TCI状态；发送下行控制信息(DCI)以及接收上行传输；

本申请实施例的有益效果之一在于：终端设备根据下行控制信息(DCI)指示的上行传输方案，基于第一上行或联合TCI状态和/或第二上行或联合TCI状态进行上行传输。由此，终端设备能够在至少一种多panel上行传输方案和/或至少一种单panel上行传输方案之间进行切换，可以获得更加鲁棒的上行传输性能，从而提高上行传输吞吐量或可靠性。

在本申请实施例中，术语“用户设备”(UE，User Equipment)或者“终端设备”(TE，Terminal Equipment或Terminal Device)例如是指通过网络设备接入通信网络并接收网络服务的设备。终端设备可以是固定的或移动的，并且也可以称为移动台(MS，Mobile Station)、终端、用户台(SS，Subscriber Station)、接入终端(AT，Access Terminal)、站，等等。

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TRP101、第二TRP102和终端设备103。其中，第一TRP101和第二TRP102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TRP101、第二TRP102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sDCI mTRP，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mDCI mTRP，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。
以终端设备103在mTRP场景下进行PUSCH发送为例，如图1所示，终端设备103以PUSCH重复(PUSCH repetition)的方式发送PUSCH。例如，在时隙1向第一TRP101发送，在时隙2向第二TRP102发送，以此类推。
终端设备被配置了两个SRS资源集合(SRS resource set)，例如，为终端设备103配置第一TRP101对应的第一SRS资源集合(1st SRS resource set)；为终端设备103配置第二TRP102对应的第二SRS资源集合(2nd SRS resource set)。
由于第一TRP101和第二TRP102在地理位置上的差异，终端设备可能基于不同的预编码矩阵、SRI(SRS resource indicator)、功控参数等发送参数向第一TRP101和/或第二TRP102发送PUSCH。此外，终端设备基于第一SRS资源集合、第二SRS资源集合获得针对第一TRP101、第二TRP102的发送参数。
以发送参数为SRI(SRS resource indicator)为例，对于动态上行授权(dynamic UL grant)，DCI中的两个SRI字段分别指示两个SRS资源集合中的SRS资源；对于配置授权(configured grant)，两个SRI被RRC配置给两个SRS资源集合。因此，终端设备需要知晓PUSCH repetition与SRS资源集合的映射关系，即知晓每个PUSCH repetition应该基于哪一个SRS资源集合进行发送。
对于Rel-17，终端设备在每次上行传输时只使用一个panel。即使终端设备有多个 panel，Re-17也不支持使用多个panel同时进行上行传输。Rel-18将对终端设备同时多panel上行传输进行研究和标准化，并且基于前面所述的unified TCI框架和mTRP场景。目前，同时多panel上行传输已经被确定为Rel-18的立项内容之一，Rel-18的标准化工作尚未开始。
针对上述问题的至少之一，本申请实施例提供在多TRP场景中基于统一TCI进行上行传输的方法、装置以及系统。

图3是本申请实施例的上行传输方案的一示例图，对上行传输方案0进行了示意性说明。如图3所示，终端设备同时使用两个panel进行上行传输，并且两个panel分别向两个TRP进行传输。
图4是本申请实施例的上行传输方案的另一示例图，对上行传输方案1或2进行了示意性说明。如图4所示，终端设备同时使用两个panel进行上行传输，并且两个panel只向某一个TRP进行传输。
图5是本申请实施例的上行传输方案的另一示例图，对上行传输方案3或4进行了示意性说明。如图5所示，终端设备使用一个panel进行上行传输，并且该panel只向某一个TRP进行传输。
对于上行传输方案5或6，可以参考图1进行示意性说明。与传输方案0不同，无论终端设备具有一个panel还是两个panel，上行传输方案5或6中终端设备在进行上行传输时只使用一个panel，但以TDM的方式在不同的时间单元向不同的TRP进行传输。
以下再对SRS资源集合和功率控制参数(简称功控参数)进行说明。
在一些实施例中，所述第一上行传输基于第一SRS资源集合，所述第二上行传输基于第二SRS资源集合。例如，表2中的“上行TCI状态或联合TCI状态”可以被等价替换为“SRS资源集合”。
在一些实施例中，第i个SRS资源集合与第i个panel关联，i＝1,2。例如，终端设备使用第i个panel发送第i个SRS资源集合内的一个或多个SRS，网络设备基于SRS可以获得第i个panel到网络设备的上行信道的信道状态信息，从而确定适合第i个panel使用的上行波束、SRI、TPMI(Transmission Precoding Matrix Information)、功控参数等。SRI可以由DCI中的SRS resource indicator字段或Second SRS resource indicator字段指示，简称为由SRI字段指示。TPMI可以由DCI中的Precoding information and number of layers字段或Second Precoding information字段指示，简称为由TPMI字段指示。考虑到终端设备使用相同的天线对SRS和其他上行信号(例如PUSCH)进行发送，终端设备基于第i个SRS资源集合进行上行传输，也可以等价于终端设备使用第i个panel进行上行传输。
例如，SRI字段可以是标准TS 38.212中的SRS resource indicator字段或Second SRS resource indicator字段，TPMI字段可以是标准TS 38.212中的Precoding information and number of layers字段或Second Precoding information字段；本申请不限于此。
在一些实施例中，第i个SRS资源集合与第i个上行TCI状态或联合TCI状态关联，i＝1,2。例如，终端设备在基于第i个SRS资源集合进行上行传输时，使用的上行波束基于第i个上行TCI状态或联合TCI状态确定。在终端设备基于第i个SRS资源集合进行上行传输等价于使用第i个panel进行上行传输的情况下，终端设备第i个panel的上行波束基于第i个上行TCI状态或联合TCI状态确定。
在一些实施例中，第i套功控参数基于第i个上行TCI状态(UL-TCIState)或联合TCI状态(DLorJoint-TCIState)确定，i＝1,2。功控参数包括目标接收功率(P0)、路损补偿因子(alpha)、路损参考信号(PL-RS，Pathloss-Reference Signal)和闭环索引(closed loop index)中的至少一种。例如，一个上行TCI状态或联合TCI状态包括或关联一套功控参数。
图6是本申请实施例的功控参数和上行TCI状态或联合TCI状态关联的一示例图。如图6所示，指示上行TCI状态或联合TCI状态的RRC IE(Information Element)，即UL-TCIState和DLorJoint-TCIState，包括标识为pathlossReferenceRS-Id的路损参考信号，通过Uplink-powerControlId关联目标接收功率(图6中p0)、路损补偿因子(图6中alpha)和闭环索引(图6中closedLoopIndex)。第i套功控参数进一步与第i个SRS资源集合关联，并与图6中的第i个SRI字段关联，i＝1,2。图6中的两个TPC(Transmit Power Control)字段分别对应closedLoopIndex＝0(l＝0)和closedLoopIndex＝1(l＝1)。
在一些实施例中，第i套功控参数基于与第i个SRS资源集合关联的SRI字段确定，i＝1,2。
图7是本申请实施例的功控参数和SRI关联的一示例图。如图7所示，第i个SRI字段关联某个sri-PUSCH-PowerControlId，进而关联第i套功控参数，即第i个SRI字段通过sri-PUSCH-PowerControlId与第i套功控参数关联，i＝1,2。
在一些实施例中，第i个SRI字段或TPMI字段基于第i个SRS资源集合确定，i＝1,2。
在一些实施例中，确定上行波束、SRI和TPMI的具体方法可以沿用现有技术。
在一些实施例中，对于基于单下行控制信息(sDCI)的多传输接收点(mTRP)，所述终端设备根据所述下行控制信息进行所述上行传输。
在一些实施例中，对于基于多下行控制信息(mDCI)的多传输接收点(mTRP)， 所述终端设备根据所述下行控制信息进行所述上行传输。
在一些实施例中，终端设备可用的上行传输方案包括同时多panel上行传输方案，或者，包括多panel上行传输方案和单panel上行传输方案。例如，终端设备的可用上行传输方案可以是表1或表2所述的多个上行传输方案中的其中之一或者任意组合。
例如，终端设备可用的上行传输方案包括：
-上行传输方案0，或者，
-上行传输方案0和上行传输方案1～6中的至少一种，或者，
-上行传输方案1～2中的至少一种，或者，
-上行传输方案1～2中的至少一种和上行传输方案3～6中的至少一种。
例如，对于基于sDCI的mTRP，终端设备可用的上行传输方案包括：

例如，对于基于mDCI的mTRP，终端设备可用的上行传输方案包括：
-上行传输方案1～2中的至少一种，或者，
-上行传输方案1～2中的至少一种和上行传输方案3～6中的至少一种。
以下再对如何配置和/或指示上行传输方案进行示意性说明。
在一些实施例中，在终端设备可用的上行传输方案包括多于一种上行传输方案的情况下，终端设备所使用的上行传输方案由DCI指示，和/或，由RRC信令配置。
例如，终端设备可用的上行传输方案包括上行传输方案0～2中的至少两种，DCI格式0_1和/或0_2指示终端设备所使用的上行传输方案。
例如，终端设备可用的上行传输方案包括上行传输方案0以及包括上行传输方案3、4中的至少一种，并且由DCI格式0_1和/或0_2指示终端设备所使用的上行传输方案。
例如，终端设备可用的上行传输方案包括上行传输方案0以及包括上行传输方案3、4、5、6中的至少一种，并且由DCI格式0_1和/或0_2指示终端设备所使用的上行传输方案。
例如，终端设备可用的上行传输方案包括上行传输方案0以及包括上行传输方案3、4、5、6中的至少一种，并且由RRC信令指示终端设备所使用的上行传输方案。
在一些实施例中，终端设备所使用的上行传输方案由DCI中的SRS资源集合指示字段或SRS请求字段指示。
在一些实施例中，通过RRC信令为所述终端设备配置多个上行传输方案，并由所 述下行控制信息指示所述多个上行传输方案中的一个上行传输方案。
例如，终端设备可用的上行传输方案包括上行传输方案0、上行传输方案3、4中的至少一种、上行传输方案5、6中的至少一种，RRC信令为终端设备配置一个RRC IE(记为“multi-panel-simultaneous”)，DCI格式0_1和/或0_2指示终端设备使用上行传输方案0、3、4中的一种，或者，RRC信令为终端设备配置一个RRC IE(记为“multi-panel-TDM”)，DCI格式0_1和/或0_2指示终端设备使用上行传输方案5、6、3、4中的一种。在终端设备被指示了两个上行TCI状态或联合TCI状态的情况下，终端设备根据RRC信令可以知晓是使用两个TCI状态同时进行上行传输(方案0)，还是使用两个TCI状态以TDM方式进行上行传输(方案5、6)，通过DCI信令可以进一步实现在使用两个TCI状态的上行传输方案(方案0)和使用一个TCI状态的上行传输方案(方案3、4)之间的动态切换，或者，实现在使用两个TCI状态的上行传输方案(方案5、6)和使用一个TCI状态的上行传输方案(方案3、4)之间的动态切换。
在一些实施例中，对于上行传输方案0、1、2中的任意一种，其包括多于一种子方案。例如，包括以下至少一种子方案：
-空分复用(SDM，Spatial Division Multiplex)：终端设备的两个panel分别在两个相同的资源上发送不同的layer(层)。
-频分复用1(FDM1，Frequency Division Multiplex 1)：终端设备的两个panel分别在两个频分复用的资源上发送不同的layer(层)。
-频分复用2(FDM2，Frequency Division Multiplex 2)：终端设备的两个panel分别在两个频分复用的资源上发送两个副本。
在一些实施例中，对于上行传输方案5、6中的任意一种，其包括多于一种子方案。例如，包括以下至少一种子方案：
-循环映射(Cyclic mapping)：终端设备按照1、2、1、2的顺序进行TDM发送。
-顺序映射(Sequential mapping)：终端设备按照1、1、2、2的顺序进行TDM发送。
这里1、2分别表示第一个和第二个上行或联合TCI状态，或者，SRS资源集合，或者，TRP。
在一些实施例中，子方案由RRC信令配置。例如，RRC信令配置终端设备使用FDM1子方案，则错误！未找到引用源。中的上行传输方案0被替换为该子方案(对于传输方案1、2同样适用)，在此基础上，可以使用前面所述的任何一种方法在多个上行传输方案中确定一个上行传输方案。
在一些实施例中，子方案由DCI信令指示。例如，错误！未找到引用源。中的上行传输方案0被替换为三种上行传输方案0a、0b、0c(对于传输方案1、2同样适用)，分别对应三种子方案，DCI对所使用的子方案进行指示，在此基础上，可以使用前面所述的任何一种方法在多个上行传输方案中确定一个上行传输方案。
以下对PUCCH传输进行说明，以上方案同样适用，与之前相同之处不再赘述。
在一些实施例中，终端设备接收传输配置指示(TCI)状态指示信息，所述TCI状态指示信息指示第一上行或联合TCI状态和第二上行或联合TCI状态；
所述终端设备接收下行控制信息(DCI)；以及
所述终端设备在所述下行控制信息指示的物理上行控制信道(PUCCH)资源上，基于所述第一上行或联合TCI状态和/或所述第二上行或联合TCI状态传输PUCCH。
在一些实施例中，物理上行控制信道(PUCCH)资源被RRC信令或MAC CE配置为使用多个上行传输方案中的一个上行传输方案，以及在由所述DCI指示PUCCH资源时，所述终端设备使用配置的上行传输方案传输PUCCH。
在一些实施例中，“PUCCH资源由DCI指示”可以被等价替换为“PUCCH资源由DCI的PUCCH resource indicator字段和DCI的CCE(Control Channel Element)索引确定”。
例如，DCI格式1_1或DCI格式1_2指示了两个上行TCI状态或联合TCI状态，在上述两个TCI状态的作用时间内，DCI格式1_1或DCI格式1_2指示终端设备发送PUCCH。PUCCH资源基于DCI格式1_1或DCI格式1_2的PUCCH resource indicator字段，和/或，DCI格式1_1或DCI格式1_2的CCE(Control Channel Element)索引确定。PUCCH资源被RRC信令或MAC CE配置为使用某一种上行传输方案，所述上行传输方案可以基于两个TCI状态，或者，基于第一个TCI状态，或者，基于第二个TCI状态。终端设备使用所述上行传输方案发送PUCCH。
例如，在使用RRC信令配置PUCCH资源时，通过一个新的RRC IE(记为“scheme”)配置该PUCCH资源使用的上行传输方案，即与该PUCCH关联的上行传输方案。以下表3对RRC信令进行了示意性说明。RRC信令可以配置多个PUCCH资源。DCI中的PUCCH resource indicator字段在多个PUCCH资源中指示一个PUCCH资源。终端设备在发送PUCCH时，使用与该PUCCH资源关联的上行传输方案。
表3
Figure PCTCN2022090082-appb-000005
Figure PCTCN2022090082-appb-000006
例如，通过MAC CE为PUCCH资源关联一个上行传输方案。RRC配置的PUCCH资源不包括指示上行传输方案的IE，通过MAC CE将PUCCH资源与上行传输方案进行关联。当DCI指示了一个PUCCH资源时，PUCCH使用MAC CE配置的上行传输方案进行传输。
图8是本申请实施例的MAC CE的一示意图，给出一种MAC CE示意。每个PUCCH resource ID字段标识一个PUCCH资源。每个PUCCH resource ID字段关联一个或多个Si字段。一个或多个Si字段用于指示与PUCCH资源关联的上行传输方案。
例如，假设使用3个Si字段(S5～S7)，“000”表示上行传输方案0，“001”表示上行传输方案1，以此类推。未使用的Si字段(S0～S4)作为保留字段，即等价于R字段(保留字段)，可以标记为R。不失一般性，MAC CE也可以包括图8中未示出的其他字段。
图9是本申请实施例的MAC CE的另一示意图。如果Si字段为1并且其他j≠i的Sj字段为0，则表示PUCCH resource ID标识的PUCCH资源使用上行传输方案i，i＝0,1,…6。不失一般性，MAC CE也可以包括图9中未示出的其他字段。
图10是本申请实施例的MAC CE的另一示意图。C字段为0，表示PUCCH资源(PUCCH resource ID)关联一个Spatial Relation Info(Spatial Relation Info ID0)，S0、S1字段中的至少之一指示基于一个上行TCI状态或联合TCI状态的上行传输方案。例如S1字段为1表示上行传输方案3，S1字段为0表示上行传输方案4，S0字段标记为R。C字段为1，表示PUCCH资源(PUCCH resource ID)关联两个Spatial Relation Info(Spatial Relation Info ID0，Spatial Relation Info ID1)，S0、S1、S2、S3字段中的至少之 一指示基于两个上行TCI状态或联合TCI状态的上行传输方案。例如，使用S0、S1字段，“00”表示上行传输方案0，“01”表示上行传输方案5，“10”表示上行传输方案6，S2、S3字段标记为R。不失一般性，MAC CE也可以包括图10中未示出的其他字段。
在一些实施例中，PUCCH使用unified TCI，发送PUCCH所使用的UL TX spatial filter基于上行或联合TCI状态确定，所使用的上行传输方案基于RRC配置或MAC CE配置确定。
在一些实施例中，PUCCH不使用unified TCI，发送PUCCH所使用的UL TX spatial filter基于Spatial Relation Info确定，所使用的上行传输方案基于RRC配置或MAC CE配置确定。
例如，如图10所示，一个PUCCH可以基于一个Spatial Relation Info进行传输，或者，基于两个Spatial Relation Info进行传输，取决于DCI指示的PUCCH资源关联一个还是两个Spatial Relation Info。在上行传输方案基于RRC配置的情况下，PUCCH的上行传输方式基于RRC配置的“scheme”IE确定。在上行传输方案基于MAC CE配置确定的情况下，PUCCH的上行传输方式基于Si字段确定。
在一些实施例中，当DCI指示PUCCH资源时，PUCCH使用该DCI指示的上行传输方案进行传输。例如，在两个上行TCI状态或联合TCI状态的作用时间内，DCI格式1_1或1_2指示了一个PUCCH资源，该DCI也指示发送该PUCCH所使用的上行传输方案。如果DCI指示的上行传输方案使用第i个上行TCI状态或联合TCI状态，则第i个状态指上述两个上行TCI状态或联合TCI状态中的第i个状态，i＝1,2。
以上各个实施例仅对本申请实施例进行了示例性说明，但本申请不限于此，还可以在以上各个实施例的基础上进行适当的变型。例如，可以单独使用上述各个实施例，也可以将以上各个实施例中的一种或多种结合起来。
由上述实施例可知，终端设备根据下行控制信息(DCI)指示的上行传输方案，基于第一上行或联合TCI状态和/或第二上行或联合TCI状态进行上行传输。由此，终端设备能够在至少一种多panel上行传输方案和/或至少一种单panel上行传输方案之间进行切换，可以获得更加鲁棒的上行传输性能，从而提高上行传输吞吐量或可靠性。
第二方面的实施例
本申请实施例提供一种信号接收方法，从网络设备侧进行说明。本申请实施例可以与第一方面的实施例结合起来，也可以单独实施。与第一方面的实施例相同的内容不再 赘述。

1101，网络设备发送传输配置指示(TCI)状态指示信息，所述TCI状态指示信息指示第一上行或联合TCI状态和第二上行或联合TCI状态；

1103，所述网络设备接收上行传输；其中，由终端设备根据所述下行控制信息指示的上行传输方案，基于所述第一上行或联合TCI状态和/或所述第二上行或联合TCI状态进行所述上行传输。
值得注意的是，以上附图11仅对本申请实施例进行了示意性说明，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。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11的记载。
