Description

传输配置指示的配置方法及装置 技术领域
本公开涉及通信领域，尤其涉及传输配置指示的配置方法及装置。
背景技术
5G即NR(New Radio，新空口)系统相关标准化正在3GPP(3rd Generation Partnership Project，第三代合作伙伴计划)中进行。
在5G系统中，终端与基站完成随机接入，并建立好RRC(Radio Resource Control,无线资源控制)连接之后，基站可以根据终端上报的测量结果确定多个与所述终端对应的TCI(transmission configuration indication，传输配置指示)状态，每个TCI状态的QCL(Quasi-Co-Location，准共址)的类型为type D时，用于指示spatial Rx parameter，即用于指示终端的一个接收beam(波束)。目前TCI状态的数目最多是64个。
目前，针对PDSCH(Physical Downlink Shared Channel,物理下行共享信道)的接收，基站使用RRC信令配置了最多64个TCI状态之后，需要使用激活信令，例如MAC CE(Media Access Control Element，媒体访问控制层控制单元)信令来激活其中的任意8个TCI状态，如果每个TCI状态对应MAC CE中的1个比特，则最多需要64比特的MAC CE来激活其中的8个TCI状态，从而造成MAC CE的信令开销较大。

应当理解，尽管在本公开可能采用术语第一、第二、第三等来描述各种信息，但这些信息不应限于这些术语。这些术语仅用来将同一类型的信息彼此区分开。例如，在不脱离本公开范围的情况下，第一信息也可以被称为第二信息，类似地，第二信息也可以被称为第一信息。取决于语境，如在此所使用的词语“如果”可以被解释成为“在……时”或“当……时”或“响应于确定”。
本公开实施例提供了一种传输配置指示的配置场景示意图，参照图1所示。基站100可以在与终端建立无线资源控制RRC连接之后，发送激活信令到终端200。终端200根据激活信令在多个TCI分组中激活目标TCI 分组所包括的所有TCI状态。进一步地，基站100再发送配置信令到终端200，在目标TCI分组中指示目标TCI状态，终端通过目标TCI状态对应的参考信号相对应的接收波束接收配置信令所调度的物理下行信道。
上述实施例中，通过将TCI状态进行分组，从而可以在激活信令中通过较少的比特数目来表征每个TCI分组是否被激活，一旦目标TCI分组被激活，则所述目标TCI分组所包括的所有TCI状态均被激活，减少了激活信令的开销，节省了基站资源。
下面先从基站侧介绍本公开实施例提供的传输配置指示的配置方法。
本公开实施例提供了一种传输配置指示的配置方法，可以用于基站。参照图2根据一示例性实施例示出的一种传输配置指示的配置方法流程图，可以包括以下步骤：
在步骤101中，在与终端建立无线资源控制RRC连接之后，发送激活信令到所述终端；其中，所述激活信令用于激活目标TCI分组中所包括的所有TCI状态，所述目标TCI分组中包括多个TCI状态；
在步骤102中，发送配置信令到所述终端，所述配置信令用于指示所述终端采用目标接收波束接收所述配置信令所调度的物理下行信道，所述目标接收波束是与目标TCI状态对应的参考信号RS相对应的接收波束，所述目标TCI状态是所述目标TCI分组中由所述配置信令所指示的其中一个TCI状态。
上述实施例中，基站可以在与终端建立RRC连接之后，发送激活信令到终端，从而激活目标TCI分组中的所有TCI状态，进一步地，再由基站发送配置信令到终端，在激活的目标TCI分组中指示目标TCI状态对应的参考信号相对应的接收波束为目标接收波束，从而由终端采用目标接收波束接收所述配置信令所调度的物理下行信道。在上述过程中，通过将TCI状态进行分组，从而可以在激活信令中通过较少的比特数目来表征每个TCI分组是否被激活，一旦目标TCI分组被激活，则所述目标TCI分组所包括的所有TCI状态均被激活，减少了激活信令的开销，节省了基站资源。
针对上述步骤101，基站可以按照相关技术先向终端发送测量配置信息，所述测量配置信息用于让终端上报波束测量结果给所述基站。基站基于终端上报的波束测量结果确定TCI状态集合。
其中，所述波束测量结果可以包括波束对应的RS(Reference Signal，参考信号)标识和L1-RSRP(Layer 1-Reference Signal Receiving Power，物理层参考信号接收功率)等，RS标识可以包括RS类型和索引号，所述RS类型是指参考信号可以是SSB(Synchronization Signal Block，同步信号块)或CSI-RS(channel state information reference signal，信道状态信息参考信号)。
本步骤中，基站与终端建立RRC连接之后，可以发送激活信令到所述终端，所述激活信令用于激活目标TCI分组中所包括的所有TCI状态，所述目标TCI分组中包括多个TCI状态。可选地，所述激活信令为MAC CE信令。
本公开实施例中，为了减少激活信令开销，可以对与该终端对应的所有TCI状态进行分组。可选地，可以将空间信息相近的TCI状态分为一组，也就是说将基站发送RS时使用的波束方向接近的多个RS对应的TCI状态分为一组，或将终端接收RS时使用的波束方向接近的RS所分别对应的TCI状态分为一组。其中，分为一组的TCI状态的序号可以相邻。
如图3A所示，将基站发送RS时使用的波束方向接近的发送波束T 0、T 1、T 2、T 3分别对应的RS对应的TCI状态TCI#0、TCI#1、TCI#2、TCI#3划分为一组，将基站发送RS时使用的波束方向接近的发送波束T 4、T 5、T 6、T 7分别对应的RS对应的TCI状态TCI#4、TCI#5、TCI#6、TCI#7划分为另一组。
或者如图3B所示，可以将终端接收RS是使用的波束方向接近的接收波束R 0、R 1、R 2、R 3分别对应的RS对应的TCI状态TCI#8、TCI#9、TCI#10、TCI#11划分为一组，将终端接收RS是使用的波束方向接近的接收波束R 4、R 5、R 6、R 7分别对应的RS对应的TCI状态TCI#12、TCI#13、 TCI#14、TCI#15划分为另一组。
在本公开实施例中，可选地，每个TCI分组中包括相同数目的TCI状态，例如每个TCI分组中包括2、4或8个TCI状态。考虑到MAC CE信令一般激活8个TCI状态，因此，本公开实施例中，每个TCI分组所包括的TCI状态的最大数目可以为8。
另外，在本公开实施例中，不同TCI分组中可以没有相同的TCI状态，也可以有相同的TCI状态，任意两个TCI分组中所包括的相同的TCI状态的数目应小于每个TCI分组中所包括的TCI状态的总数目。
例如将4个TCI状态分为一组，每个TCI分组中所包括的TCI状态的总数目为4，则第一组可以包括TCI#0、TCI#1、TCI#2、TCI#3，第二组可以包括TCI#4、TCI#5、TCI#6、TCI#7。
或者第一组可以包括TCI#0、TCI#1、TCI#2、TCI#3，第二组可以包括TCI#3、TCI#4、TCI#5、TCI#6。上述两个TCI分组包括相同的TCI状态的数目为1，该相同的TCI状态为TCI#3。
基站在发送激活信令到终端时，可以发送用于表征每个TCI分组所包括的所有TCI状态是否被激活的激活信令到所述终端，这样终端可以通过激活信令在所有的TCI分组中确定需要激活的目标TCI分组，从而激活目标TCI分组所包括的所有TCI状态。
如果将64个TCI状态分为N组，则需要N比特来指示激活的是哪个目标TCI分组，当前比特的数值为1表示激活该目标TCI分组中所有TCI状态，当前比特的数值为0则表示不激活该TCI分组所包括的所有TCI状态。或者数值1表示不激活该TCI分组所包括的所有TCI状态，数值为0则表示该目标TCI分组中所有TCI状态，本公开对此不作限制。
例如，每个TCI分组包括4个TCI状态，且任意两个TCI分组之间不包括相同的TCI状态，那么64个TCI状态一共分为16组，则激活信令MAC CE需要发送16个比特到终端，以便终端确定需要激活的目标TCI分组。假设需要激活第一组和第三组，则基站通过MAC CE发送的16比 特的数值依次为0000 0000 0000 0101，由右到左分别代表需要激活的目标TCI分组为第一组和第三组。
如果第一组目标TCI分组包括TCI#0、TCI#1、TCI#2、TCI#3，第三组目标TCI分组包括TCI#8、TCI#9、TCI#10、TCI#11，则基站通过MAC CE发送上述16个比特到终端，终端就可以确定需要激活目标TCI分组中所有的TCI状态，即激活的TCI状态包括：TCI#0、TCI#1、TCI#2、TCI#3、TCI#8、TCI#9、TCI#10、TCI#11。
通过上述过程可以看出，相关技术中激活信令MAC CE需要发送64个比特到终端，终端才能确定需要激活的8个TCI状态，而采用本公开实施例提供的方法，如果任意两个TCI分组中不包括相同的TCI状态，则激活信令MAC CE只需要发送N个比特到终端，终端就可以激活目标TCI分组中的所有TCI状态，其中N＝64/X，X是每个TCI分组中所包括的TCI状态的数目，可以为2、4或8。因此，基站只需要发较少的比特就可以实现让终端在64个TCI状态中激活其中8个TCI状态的目的，减少了激活信令的开销。
针对上述步骤102，可选地，参照4所示，图4是根据图2所示的实施例示出的另一种传输配置指示的配置方法流程图，102可以包括以下步骤：
在步骤102-1中，将所述目标TCI分组所包括的所有TCI状态按照TCI状态标识由小到大的顺序排列，确定所述目标TCI分组所包括的每个TCI状态对应的序号；
本步骤中，基站在确定了目标TCI分组之后，可以将目标TCI分组所包括的所有TCI状态按照TCI状态标识由小到大的顺序排列，从而为目标TCI分组所包括的每个TCI状态确定对应的序号。
假设目标TCI分组为第一组和第三组，需要激活的所有TCI状态包括TCI#0、TCI#1、TCI#2、TCI#3、TCI#8、TCI#9、TCI#10、TCI#11，则需要激活的TCI状态标识和序号之间的对应关系如表1所示。
Figure PCTCN2018097665-appb-000001
表1
在步骤102-2中，确定所述目标TCI状态对应的目标序号；
本步骤中，基站可以在表1中确定目标TCI状态对应的目标序号。例如目标TCI状态为TCI#9，则目标序号为5。
在步骤102-3中，发送携带所述目标序号的配置信令到所述终端。
本步骤中，基站可以将携带目标序号的配置信令发送给所述终端。可选地，所述配置信令可以为DCI(Downlink Control Information，下行控制信息)信令。
在本公开实施例中，为了将所述目标序号携带在配置信令中，可以将目标序号按照相关技术中的二进制进行转换，获得目标二进制值，进一步地，在配置信令中只需要携带目标二进制值即可。例如，目标序号为5，转换为二进制后得到的目标二进制值为101。
终端接收到配置信令后，可以根据配置信令中携带的目标序号在已激活的8个TCI状态中确定目标TCI状态为TCI#9，进一步地，可以将与TCI#9对应的接收波束作为目标接收波束，来接收DCI信令所调度的物理下行信道。其中，所述物理下行信道可以是PDCCH(physical downlink control channel，物理下行控制信道)或PDSCH(physical downlink shared channel，物理下行共享信道)。
上述实施例中，基站可以在激活了目标TCI分组后，通过配置信令让终端在被激活的目标TCI分组中快速确定其中一个TCI状态，即目标TCI状态，在确保终端业务的情况下，同样实现了节省激活信令开销的目的。
在一实施例中，可选地，上述传输配置指示的配置方法参照5所示，图5是根据图2所示的实施例示出的另一种传输配置指示的配置方法流程图，在所述发送激活信令到所述终端之前，还可以包括以下步骤：
在步骤103中，通过目标RRC信令发送TCI状态对应表给所述终端；
本公开实施例中，所述TCI状态对应表包括TCI状态标识和信号标识之间的映射关系，所述TCI状态标识是所有TCI状态各自对应的状态标识，所述信号标识是与当前TCI状态对应的参考信号的标识。其中，信号标识可以包括参考信号类型和索引号，所述参考信号类型是指参考信号可以是SSB或CSI-RS。TCI状态对应表可以如表2所示。
TCI状态标识 信号标识
TCI#0 SSB index#1
TCI#1 SSB index#2
TCI#2 CSI-RS index#5
TCI#3 CSI-RS index#6
TCI#4 SSB index#3
…… ……
表2
基站可以在发送激活信令到终端之前，先通过目标RRC信令将表2发送给终端。终端接收后，如果后续确定目标TCI为TCI#3，则终端可以根据表2将接收CSI-RS index#6的接收波束R x作为目标接收波束，从而通过R x来接收配置信令所调度的物理下行信道。当然，如果目标TCI为TCI#3，还可以说明基站是通过发送波束T x来发送CSI-RS index#6，基站侧的发送波束T x与终端侧的接收波束R x是对应的，也就是说终端侧需要通过接收 波束R x来接收发送波束T x所发送的物理下行信道。
上述实施例中，基站可以在发送激活信令到终端之前，通过目标RRC信令将TCI状态对应表发送给终端。其中，所述TCI状态对应表包括TCI状态标识和信号标识之间的映射关系，所述TCI状态标识是所有TCI状态各自对应的状态标识，所述信号标识是与当前TCI状态对应的参考信号的标识。本公开实施例中，由基站将TCI状态对应表发送给终端，便于终端后续根据该TCI状态对应表，确定接收所述配置信令所调度的物理下行信道的目标接收波束，可用性高。
在一实施例中，可选地，基站还可以通过目标RRC信令发送分组指示信息给终端，所述分组指示信息用于指示所述TCI状态对应表中每个TCI状态标识所对应的TCI分组，例如表3所示。
TCI状态标识 信号标识 分组指示信息
TCI#0 SSB index#1 第一组
TCI#1 SSB index#2 第一组
TCI#2 CSI-RS index#5 第一组
TCI#3 CSI-RS index#6 第一组
TCI#4 SSB index#3 第二组
…… …… ……
表3
在本公开实施例中，终端在接收到包括分组指示信息的目标RRC信令之后，可以进一步确定每个TCI状态所属的TCI分组，后续基站可以在激活信令中通过较少的比特数目来表征每个TCI分组是否被激活，一旦目标TCI分组被激活，则所述目标TCI分组所包括的所有TCI状态均被激活，从而减少激活信令的开销。
在上述实施例中，可选地，所述分组指示信息仅需要给出分为一组的TCI状态的数目L和每相邻的两个TCI分组中相同的TCI状态的数目M。 例如当L＝4，M＝0时，预定义的分组指示信息为连续的L个TCI状态为一组，即TCI#0、TCI#1、TCI#2、TCI#3属于第一组，TCI#4、TCI#5、TCI#6、TCI#7属于第二组，依次类推。又或者，基站不需要发送任何分组指示信息给终端，即L和M的值也是预定义好的，将上述分组指示信息直接写入基站芯片和终端芯片中，相应地，基站无需再通过目标RRC信令发送分组指示信息给终端，终端可以直接通过自身芯片获得分组指示信息，节省了基站和终端之间进行交互的信令资源。
下面再从终端侧介绍本公开实施例提供的传输配置指示的配置方法。
本公开实施例提供了另一种传输配置指示的配置方法，可以用于终端。参照图6根据一示例性实施例示出的另一种传输配置指示的配置方法流程图，可以包括以下步骤：
在步骤201中，在与基站建立无线资源控制RRC连接之后，接收所述基站发送的激活信令；
在步骤202中，激活所述激活信令所指示的目标TCI分组所包括的所有TCI状态；其中，所述目标TCI分组中包括多个TCI状态；
在步骤203中，在接收到所述基站发送的配置信令之后，确定目标接收波束；其中，所述目标接收波束是与目标TCI状态对应的参考信号相对应的接收波束，所述目标TCI状态是所述目标TCI分组中由所述配置信令所指示的其中一个TCI状态；
在步骤204中，通过所述目标接收波束，接收所述配置信令所调度的物理下行信道。
上述实施例中，终端可以在与基站建立了RRC连接之后，接收基站发送的激活信令，根据该激活信令激活目标TCI分组中所包括的所有TCI状态。进一步地，根据接收到的配置信令，在目标TCI分组中确定目标TCI状态，并将与所述目标TCI状态对应的参考信号相对应的接收波束作为目标接收波束。终端可以通过所述目标接收波束，接收所述配置信令所调度的物理下行信道。在上述过程中，通过将TCI状态进行分组，基站可以在 激活信令中通过较少的比特数目来表征每个TCI分组是否被激活，终端可以根据激活信令激活所述目标TCI分组所包括的所有TCI状态，减少了激活信令的开销，节省了基站资源。
针对上述步骤201，终端可以先按照相关技术接收基站发送的测量配置信息，从而根据测量配置信息上报波束测量结果给基站，以便基站确定TCI状态集合。所述波束测量结果可以包括波束的RS标识和L1-RSRP等，RS标识可以包括RS类型和索引号，所述RS类型是指参考信号可以是SSB或CSI-RS。
终端在与基站建立RRC连接之后，可以按照相关技术接收基站发送的激活信令。可选地，所述激活信令可以为MAC CE信令。
针对上述步骤202，终端按照激活信令的指示激活目标TCI分组所包括的所有TCI状态。
在本公开实施例中，每个TCI分组均包括多个TCI状态，每个TCI分组中包括相同数目的TCI状态，例如每个TCI分组中包括2、4或8个TCI状态。考虑到MAC CE信令一般激活8个TCI状态，因此，本公开实施例中，每个TCI分组所包括的TCI状态的最大数目可以为8。
另外，不同TCI分组中可以没有相同的TCI状态，也可以有相同的TCI状态，任意两个TCI分组中所包括的相同的TCI状态的数目应小于每个TCI分组中所包括的TCI状态的总数目。
基站在发送激活信令到终端时，可以发送用于表征每个TCI分组所包括的所有TCI状态是否被激活的激活信令到所述终端。终端根据激活信令来激活目标TCI分组所包括的所有TCI状态。
例如，每个TCI分组包括4个TCI状态，且任意两个TCI分组之间不包括相同的TCI状态，那么64个TCI状态一共分为16组，则激活信令MAC CE需要发送16个比特到终端，基站通过MAC CE发送的16比特的数值依次为0000 0000 0000 0101，由右到左分别代表需要激活的目标TCI分组为第一组和第三组。终端根据激活信令确定目标TCI分组为第一组和 第三组，则终端需要激活第一组和第三组所包括的所有TCI状态。
针对上述步骤203，终端在接收到所述基站发送的配置信令之后，确定目标接收波束的过程可以参照7所示，图7是根据图6所示的实施例示出的另一种传输配置指示的配置方法流程图，步骤203可以包括以下步骤：
在步骤203-1中，对所述目标TCI分组所包括的所有TCI状态按照TCI状态标识由小到大的顺序排列，确定所述目标TCI分组所包括的每个TCI状态对应的序号；
本步骤中，终端在激活了目标TCI分组所包括的所有TCI状态之后，可以将上述TCI状态按照TCI状态标识由小到大的顺序排列，确定所述目标TCI分组所包括的每个TCI状态对应的序号，同样如表1所示。
在步骤203-2中，将对应的所述序号与所述配置信令中携带的目标序号匹配的TCI状态，确定为目标TCI状态；
本步骤中，为了将目标TCI分组所包括的所有TCI状态对应的序号与所述目标序号进行匹配，终端可以将表1中的每个TCI状态对应的序号按照二进制进行转换，从而获得所述目标TCI分组所包括的每个TCI状态对应的二进制值，如表4所示。
Figure PCTCN2018097665-appb-000002
表4
本公开实施例中，基站会在配置信令，例如DCI信令中同样通过二进制的方式，携带与目标TCI状态对应的目标二进制值，假设为101，则终端可以根据表4确定目标TCI状态为TCI#9。
在步骤203-3中，在所述TCI状态对应表中，确定所述目标TCI状态的目标TCI状态标识对应的目标信号标识；
本步骤中，终端在确定了目标TCI状态之后，可以根据上述表3确定与目标TCI状态标识对应的目标信号标识，假设目标信号标识为SSB#4。
在步骤203-4中，将用于接收目标参考信号的接收波束作为所述目标接收波束，所述目标参考信号是所述目标信号标识所指示的参考信号。
本步骤中，终端可以将用于接收目标参考信号的接收波束作为所述目标接收波束，也就是说将接收SSB#4的接收波束R x作为目标接收波束。
上述实施例中，终端可以在激活了目标TCI分组后，在被激活的目标TCI分组中快速确定目标TCI状态，最终确定目标接收波束，在确保终端业务的情况下，实现了节省激活信令开销的目的，节省了基站资源。
针对上述步骤204，终端确定目标接收波束之后，可以按照相关技术通过该目标接收波束，接收配置信令所调度的物理下行信道。可选地，物理下行信道可以是PDCCH或PDSCH。
在一实施例中，参照8所示，图8是根据图6所示的实施例示出的另一种传输配置指示的配置方法流程图，在接收所述基站发送的激活信令之前，上述传输配置指的配置方法还可以包括以下步骤：
在步骤205中，接收所述基站通过目标RRC信令发送的TCI状态对应表；
其中，所述TCI状态对应表包括TCI状态标识和信号标识之间的映射关系，所述TCI状态标识是所有TCI状态各自对应的状态标识，所述信号标识是与当前TCI状态对应的参考信号的标识。
本步骤中，基站可以在发送激活信令到终端之前，通过目标RRC信令将上述表2发送给终端，终端按照相关技术进行接收，以便终端后续根 据该TCI状态对应表，确定接收所述配置信令所调度的物理下行信道的目标接收波束，可用性高。
在上述实施例中，终端还可以接收基站通过目标RRC信令发送的分组指示信息，所述分组指示信息用于指示所述TCI状态对应表中每个TCI状态标识所对应的TCI分组。
也就是说，基站通过目标RRC信令将表3发送给终端，终端根据分组指示信息在TCI状态对应表中确定每个TCI分组所包括的TCI状态，后续基站可以在激活信令中通过较少的比特数目来表征每个TCI分组是否被激活，一旦目标TCI分组被激活，则所述目标TCI分组所包括的所有TCI状态均被激活，从而减少激活信令的开销。
在本公开实施例中，可选地，所述分组指示信息仅需要给出分为一组的TCI状态的数目L和每相邻的两个TCI分组中相同的TCI状态的数目M。例如当L＝4，M＝0时，预定义的分组指示信息连续的L个TCI状态为一组，即为TCI#0、TCI#1、TCI#2、TCI#3属于第一组，TCI#4、TCI#5、TCI#6、TCI#7属于第二组，依次类推。又或者，基站不需要发送任何分组指示信息给终端，即L和M的值也是预定义好的，将上述分组指示信息直接写入基站芯片和终端芯片中，相应地，基站无需再通过目标RRC信令发送分组指示信息给终端，终端可以直接通过自身芯片获得分组指示信息，节省了基站和终端之间进行交互的信令资源。
本公开实施例提供了另一种传输配置指示的配置方法。参照图9根据一示例性实施例示出的另一种传输配置指示的配置方法流程图，可以包括以下步骤：
在步骤301中，基站通过目标RRC信令发送TCI状态对应表给所述终端，所述目标RRC信令还包括分组指示信息。
其中，所述TCI状态对应表包括TCI状态标识和信号标识之间的映射关系，所述TCI状态标识是所有TCI状态各自对应的状态标识，所述信号标识是与当前TCI状态对应的参考信号的标识；所述分组指示信息用于 指示所述TCI状态对应表中每个TCI状态标识所对应的TCI分组。
在步骤302中，基站发送用于表征每个TCI分组所包括的所有TCI状态是否被激活的激活信令到所述终端。
可选地，激活信令可以是MAC CE信令。此时，基站需要N比特来指示激活的是哪个目标TCI分组，N远小于64。
在步骤303中，终端激活所述激活信令所指示的目标TCI分组所包括的所有TCI状态。
其中，所述目标TCI分组中包括多个TCI状态。
在步骤304中，基站将所述目标TCI分组所包括的所有TCI状态按照TCI状态标识由小到大的顺序排列，确定所述目标TCI分组所包括的每个TCI状态对应的序号。
在步骤305中，基站确定目标TCI状态对应的目标序号。
其中，所述目标TCI状态是所述目标TCI分组中后续需要由配置信令所指示的其中一个TCI状态。
在步骤306中，基站发送携带所述目标序号的配置信令到所述终端。
其中，所述配置信令用于指示所述终端采用目标接收波束接收所述配置信令所调度的物理下行信道，所述目标接收波束是与目标TCI状态对应的参考信号RS相对应的接收波束。
在步骤307中，终端对所述目标TCI分组所包括的所有TCI状态按照TCI状态标识由小到大的顺序排列，确定所述目标TCI分组所包括的每个TCI状态对应的序号。
在步骤308中，终端将对应的所述序号与所述配置信令中携带的目标序号匹配的TCI状态，确定为目标TCI状态。
在步骤309中，终端在所述TCI状态对应表中，确定所述目标TCI状态的目标TCI状态标识对应的目标信号标识。
在步骤310中，终端将用于接收目标参考信号的接收波束作为所述目标接收波束。
其中，所述目标参考信号是所述目标信号标识所指示的参考信号。
在步骤311中，终端通过所述目标接收波束，接收所述配置信令所调度的物理下行信道。
上述实施例中，基站可以先发送目标RRC信令到终端，通过目标RRC信令将TCI状态对应表和TCI分组信息发送给终端，进一步地，基站再发送激活信令到终端，从而激活目标TCI分组中的所有TCI状态，再由基站发送配置信令到终端，在激活的目标TCI分组中指示目标TCI状态对应的参考信号RS相对应的接收波束为目标接收波束，从而由终端采用目标接收波束接收所述配置信令所调度的物理下行信道。在上述过程中，通过将TCI状态进行分组，从而可以在激活信令中通过较少的比特数目来表征每个TCI分组是否被激活，一旦目标TCI分组被激活，则所述目标TCI分组所包括的所有TCI状态均被激活，减少了激活信令的开销，节省了基站资源。

可选地，所述目标RRC信令还包括分组指示信息，所述分组指示信息用于指示所述TCI状态对应表中每个TCI状态标识所对应的TCI分组。
上述实施例中，终端还可以接收包括分组指示信息的目标RRC信令，以便终端根据分组指示信息在TCI状态对应表中确定每个TCI分组所包括的TCI状态，后续基站可以在激活信令中通过较少的比特数目来表征每个TCI分组是否被激活，一旦目标TCI分组被激活，则所述目标TCI分组所包括的所有TCI状态均被激活，从而减少激活信令的开销。
参照图16，图16是根据图14所示实施例的基础上示出的另一种传输配置指示的配置装置框图，所述确定模块530包括：
第三确定子模块531，被配置为对所述目标TCI分组所包括的所有TCI状态按照TCI状态标识由小到大的顺序排列，确定所述目标TCI分组所包括的每个TCI状态对应的序号；
第四确定子模块532，被配置为将对应的所述序号与所述配置信令中携带的目标序号匹配的TCI状态，确定为目标TCI状态；
第五确定子模块533，被配置为在所述TCI状态对应表中，确定所述目标TCI状态的目标TCI状态标识对应的目标信号标识；
第六确定子模块534，被配置为将用于接收目标参考信号的接收波束作为所述目标接收波束，所述目标参考信号是所述目标信号标识所指示的参考信号。
上述实施例中，终端可以对激活的目标TCI分组中的所有TCI状态按照TCI状态标识由小到大的顺序排列，确定所述目标TCI分组所包括的每个TCI状态对应的序号。所述序号与所述配置信令中携带的目标序号匹配的TCI状态，就是目标TCI状态，通过之前接收到的TCI状态对应表，就可以在目标TCI分组中快速确定目标TCI状态，以及相应的目标信号标识。目标信号标识所指示的参考信号即为目标参考信号，终端将用于接收 目标参考信号的接收波束作为所述目标接收波束。通过上述过程，终端可以在激活了目标TCI分组后，在被激活的目标TCI分组中快速确定目标TCI状态，最终确定目标接收波束，在确保终端业务的情况下，实现了节省激活信令开销的目的，节省了基站资源。
