Description

配置信息的接收和发送方法、装置及通信系统 技术领域
本发明实施例涉及通信技术领域，特别涉及一种配置信息的接收和发送方法、装置及通信系统。
背景技术
大规模多输入多输出(MIMO，Multiple-Input Multiple-Output)技术是新无线(NR，New radio)系统的关键技术，包括例如6GHz以下及6GHz以上频段的研究。随着频段的增加，传输中产生的衰落和损耗也会相应增大，波束成型技术由于可以有效地补偿衰落而成为大规模MIMO技术中的关键技术。
在大规模MIMO技术的研究中，为了提高传输的可靠性，允许使用同时为物理信道(例如，广播信道、数据信道、控制信道等)发送多个波束的波束成型技术。由于网络设备(例如基站)和用户设备(UE，User Equipment)均具备发送和接收多个波束的能力，因此可以通过波束管理，例如接收端和发送端分别进行波束扫描(beam sweeping)，来获得最优的发送接收波束组合。
例如，当前第三代合作伙伴计划(3GPP，3 rd Generation Partnership Project)NR系统中的下行波束管理可以包含如下的三个过程。
过程1(P1)：基站发送多个不同的波束；UE对这些波束进行测量，并选出质量较优的发送端波束。
过程2(P2)：基站发送多个不同的波束，和P1相比，P2阶段的波束更加的精细(窄)，可以是P1阶段波束的一个更小集合；UE对这些波束进行测量，并选出质量较优的发送端波束。
过程3(P3)：基站发送多个相同的波束；UE使用不同的接收端波束来接收，从而选出质量较优的接收端波束。
由此可见，通过波束管理的三个过程，UE可以获得发送端多个不同波束和接收端多个不同波束组合的波束链路对(BPL，Beam Pair Link)的质量情况。当前NR系统支持UE对多个发送端波束质量的上报，例如将质量较好的波束编号及相应的参考信号接收功率(RSRP，Reference Signal Received Power)上报给基站。波束编号例如 可以使用信道状态信息参考信号(CSI-RS，Channel State Information Reference Signal)的资源编号和/或同步信号(SS，Synchronization Signal)块(block)的时间编号来表示。
应该注意，上面对技术背景的介绍只是为了方便对本发明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发明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。

其中，基站可以包括但不限于：节点B(NodeB或NB)、演进节点B(eNodeB或eNB)以及5G基站(gNB)，等等，此外还可包括远端无线头(RRH，Remote Radio Head)、远端无线单元(RRU，Remote Radio Unit)、中继(relay)或者低功率节点(例如femeto、pico等等)。并且术语“基站”可以包括它们的一些或所有功能，每个基站可以对特定的地理区域提供通信覆盖。术语“小区”可以指的是基站和/或其覆盖区域，这取决于使用该术语的上下文。
在本发明实施例中，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。

此外，术语“网络侧”或“网络设备侧”是指网络的一侧，可以是某一基站，也可以包括如上的一个或多个网络设备。术语“用户侧”或“终端侧”或“终端设备侧”是指用户或终端的一侧，可以是某一UE，也可以包括如上的一个或多个终端设备。
以下通过示例对本发明实施例的场景进行说明，但本发明不限于此。
图1是本发明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可以包括网络设备101和终端设备102。为简单起见，图1仅以一个终端设备和一个网络设备为例进行说明，但本发明实施例不限于此。例如，网络设备101可以具有多个，以形成多TRP传输或者多panel传输。
在本发明实施例中，网络设备101和终端设备102之间可以进行现有的业务或者未来可实施的业务。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。
在本发明中，在网络设备获得终端设备上报的质量较优的波束以后，就可以在物理信道(例如，广播信道，数据信道，控制信道等)的传输中使用这些波束以获得较高的传输质量。同时，NR支持网络设备将使用的发送波束指示给终端设备，便于终端设备决定采用哪个接收波束进行对齐并接收。此外，波束指示可以等同于空间准共址(QCL，Quasi-Co-Location)指示，也可以等同于传输配置指示(TCI，Transmission Configuration Indication)状态的指示。
在NR系统中，在为物理下行控制信道(PDCCH，Physical Downlink Control Channel)进行波束指示时，可以使用无线资源控制(RRC，Radio Resource Control)信令和/或介质访问控制(MAC，Media Access Control)信令(例如MAC-CE)。例如，可以使用RRC信令为每个控制资源集合(control resource set，以下称为CORESET)配置K个TCI状态；对某个CORESET来说，当K>1时，使用MAC-CE进一步激活K个TCI状态中的一个状态；当K＝1时，无需使用MAC-CE进行激活，该RRC配置的TCI状态即为该CORESET的TCI状态。当某个下行控制信息(DCI，Downlink Control Information)传输时，其TCI状态和其实际传输所使用的CORESET的TCI状态是一致的。
在为物理下行共享信道(PDSCH，Physical Downlink Shared Channel)进行波束指示时，可以使用RRC信令和/或MAC-CE和/或DCI。例如，RRC信令中配置M个TCI状态，MAC-CE对M个状态中的2^N个TCI状态进行激活，在DCI的传输中，使用N比特来指示2^N个状态中的一个TCI状态。
由于模拟域上的接收波束成型是在信号到达天线粒子时进行的，因而对PDSCH的某些符号来说，在对其进行模拟域波束成型时，可能并没有译码出DCI中包含的TCI指示信息，因此不能选择合适的接收波束来做模拟波束成型。
因而NR中定义了时间偏移门限，即当接收到DCI的时刻和调度的PDSCH的某个符号之间的时间偏移(time offset)小于某个门限时，终端设备会假设该符号上 PDSCH的TCI状态与本时隙中配置的所有CORESET中编号(ID)最低的那个CORESET的TCI状态是一致的。当接收到DCI的时刻和调度的PDSCH的某个符号之间的时间偏移大于或等于某个门限时，终端设备会假设该符号上PDSCH的TCI状态与DCI中指示的TCI状态是一致的。在计算时间偏移时，接收到DCI的时刻也可以用某个固定的、对网络设备和终端设备双方都明确的时刻来代替。PDSCH的某个符号可以是调度的PDSCH在时间维度上占据的第一个正交频分复用(OFDM，Orthogonal Frequency Division Multiplexing)符号，也可以是调度的PDSCH在每个时隙(slot)的第一个OFDM符号，即每个slot均会计算一个时间偏移值，进而去和时间偏移门限进行比较。
除此之外，也可以不对PDSCH的TCI状态进行指示。是否会对PDSCH的TCI状态进行指示，可以取决于高层配置的指示动态TCI状态的参数TCI-PresentInDCI。RRC信令会为每个CORESET都配置参数TCI-PresentInDCI，当该参数为使能状态(enabled)时，代表在该CORESET传输的DCI会包含TCI状态指示域；而当该参数为非使能状态(disabled)时，代表在该CORESET传输的DCI不会包含TCI状态指示域。当不对PDSCH的TCI状态进行指示或者在终端设备没有收到TCI状态指示的情况下，需要定义一种默认的TCI状态，以便网络设备和终端设备按照该默认的TCI状态来进行模拟域波束的发送和接收。
图2是本发明实施例的TCI状态的示意图。如图2所示，当接收到DCI的时刻和调度的PDSCH的某个符号之间的时间偏移(offset)小于某个门限时，采用默认的DCI状态，该默认的DCI状态为本时隙中配置的所有CORESET中编号(ID)最低的CORESET的TCI状态，如图2中的A部分和B部分所示；当TCI-PresentInDCI为disabled、且接收到DCI的时刻和调度的PDSCH的某个符号之间的时间偏移大于或等于该门限时，采用调度的CORESET的TCI状态，如图2中的C部分所示；而当TCI-PresentInDCI为enabled、且接收到DCI的时刻和调度的PDSCH的某个符号之间的时间偏移大于或等于该门限时，采用DCI中指示的TCI状态，如图2中的D部分所示。
但是，在多TRP或多panel场景下，PDSCH的默认TCI状态或QCL参数可能和单点传输时是不同的，接收端(例如UE)可能会出现由于传输配置不准确而不能正确及时地接收到传输信息的情况。
以下将以NR系统和PDSCH为例，对本发明实施例进行说明；但本发明不限于此，还可以适用于任何存在类似问题的系统或场景中。
实施例1
本发明实施例提供一种配置信息的接收方法。图3是本发明实施例的配置信息的接收方法的示意图，示出了终端设备侧的情况。如图3所示，该方法包括：
步骤301，终端设备接收网络设备发送的用于对传输进行配置的配置信息；以及
步骤302，终端设备基于所述配置信息为一个或多个解调参考信号端口组分别配置或预定义一个或多个传输配置指示状态。
在本实施例中，解调参考信号端口组的TCI状态被配置或定义，例如可以是通过标准预先定义的，在这种情况下，步骤301是可选的。此外，还可以由网络设备通过RRC信令进行配置。
图4是本发明实施例的配置信息的发送和接收方法的示意图；从网络设备侧和终端设备侧进行进一步说明。如图4所示，该方法包括：
步骤401，网络设备向终端设备发送包括配置信息的RRC信令；
步骤402，终端设备基于所述配置信息，为一个或多个解调参考信号端口组配置或预定义一个或多个传输配置指示状态。
如图4所示，该方法还可以包括：
步骤403，网络设备向终端设备发送用于激活所述传输配置指示状态的MAC信令；和/或
步骤404，网络设备向终端设备发送用于激活所述传输配置指示状态的DCI。
值得注意的是，以上附图4仅对本发明实施例进行了示意性说明，但本发明不限于此。例如可以适当地调整各个步骤之间的执行顺序，此外还可以增加其他的一些步骤或者减少其中的某些步骤。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。
由此，接收端为DMRS端口组配置或预定义一个或多个TCI状态；即使是在例如多TRP或多panel的场景下，接收端也能正确并且及时地接收到发送端发送的传输信息。
在一个实施方式中，所述终端设备还可以根据所述网络设备配置的传输方案(TS， Transmission Scheme)和/或参数，确定一个或多个物理信道的DMRS端口组的TCI状态和/或QCL参数。
例如，在多TRP和/或多panel的场景下，终端设备的TS可以由高层配置成与单点传输时不同的参数。例如单点传输下，终端设备的TS可以被配置成transmission scheme 1(TS1)或者transmission scheme 2(TS2)；而在多TRP传输时，终端设备的TS可以被配置成transmission scheme 3(TS3)，在多panel传输时，终端设备的TS可以被配置成transmission scheme 4(TS4)；或者在多panel传输时，终端设备的TS可以被配置成transmission scheme 3(TS3)，在多TRP传输时，终端设备的TS可以被配置成transmission scheme 4(TS4)；或者在多TRP或多panel传输时，终端设备的TS可以都被配置成transmission scheme 3(TS3)，即同一个传输方案(TS)。
再例如，可以不通过配置的传输方案(TS)来指示终端设备进行单点传输或多点传输，而是以高层配置的其它参数来指示终端设备进行与多TRP或多panel相关联的操作。例如，使用高层配置参数a来指示终端设备进行单点传输相关联的操作，使用参数b来指示终端设备进行多点传输和/或多panel传输相关联的操作。
再例如，不使用高层配置参数来显式地指示多TRP和/或多panel相关联的操作，而是使用高层配置参数和/或MAC层的进一步指示和/或物理层的进一步指示，来隐式地指示与多TRP和/或多panel相关联的操作。例如，在上述时间偏移小于门限时，高层配置n(n>＝1)个PDSCH的TCI状态或QCL参数，还可以使用MAC信令进一步激活或指示，来确定一个或大于一个PDSCH的TCI状态或QCL参数。最终RRC配置的或其它控制信令确定的一个或大于一个PDSCH的TCI状态或QCL参数，可以隐式地反映出单点传输或多点传输或多panel传输时的PDSCH的TCI状态或QCL参数。
又例如，在上述时间偏移大于或等于门限，且调度PDSCH的CORESET的TCI-PresentInDCI设置为使能状态(enabled)时，高层配置m(m>＝1)个PDSCH的TCI状态或QCL参数，还可以使用MAC信令和/或物理层信令进一步指示，来确定一个或大于一个PDSCH的TCI状态或QCL参数。最终RRC配置的或其它控制信令确定的一个或大于一个PDSCH的TCI状态或QCL参数，可以隐式地反映出单点传输或多点传输或多panel传输时的PDSCH的TCI状态或QCL参数。
即，在多TRP和/或多panel场景下，可以给终端设备显式地配置传输方案(例 如TS3或TS4)，不同的传输方案对应不同的PDSCH的默认的TCI状态和/或QCL参数。例如，在上述时间偏移小于门限时，或者上述时间偏移大于或等于门限、且调度PDSCH的CORESET的TCI-PresentInDCI设置为使能状态(enabled)时，PDSCH的默认的TCI状态或QCL参数均由协议规定。
又或者，在多TRP和/或多panel场景下，在上述时间偏移小于门限时，或者上述时间偏移大于或等于门限、且调度PDSCH的CORESET的TCI-PresentInDCI设置为使能状态(enabled)时，PDSCH的默认的TCI状态和/或QCL参数由高层信令配置，还可以由MAC信令和/或物理层信令进一步激活或指示。
由此，根据网络设备配置的TS和/或参数，确定一个或多个物理信道的DMRS端口组的TCI状态和/或QCL参数；可以使得多TRP或多panel方案对于终端设备是透明的，能够降低终端设备的处理复杂度。
在一个实施方式中，在DCI和对应的PDSCH之间的时间偏移小于预设门限的情况下，所述PDSCH的一个或多个DMRS端口组被配置或预定义默认的TCI状态。本实施方式针对图2的A部分和B部分所示的情况。
例如，在多TRP场景下，当传输模式为非相干联合传输(NC-JT，non-coherent joint transmission)，至少两个DMRS端口组被配置或预定义默认的TCI状态；当传输模式为动态点选择(DPS，Dynamic Point Selection)模式，一个DMRS端口组被预定义默认的TCI状态。
例如，当时间偏移小于时间偏移门限时，终端设备会假设PDSCH的一个DMRS端口组和最近的时隙中的具有最低CORESET-ID的CORESET的TCI状态是QCL的(quasi co-located，即TCI状态相同)。当终端设备被两个或两个以上TRP调度时，不同TRP调度的PDSCH的TCI状态是不同的，而具有最低CORESET-ID的CORESET的TCI状态可能仅和其中一个TRP调度的PDSCH的TCI状态一致。在这种情况下，如果仍使用具有最低CORESET-ID的CORESET的TCI状态作为时间偏移小于门限时的默认TCI状态，终端设备可能仅能收到一个TRP发来的PDSCH。
在本实施方式中，所述PDSCH的DMRS端口组的天线端口和一个或多个控制资源集合中的一个或多个参考信号集合是空间准共址的。例如，可以针对每个DMRS端口组，也可以针对部分或者所有的DMRS端口组。
例如，所述一个或多个参考信号集合是具有最低CORESET-ID的CORESET中的 被激活的一个TCI状态所对应的至少两个参考信号集合。例如，在多TRP或多panel的场景下，具有最低CORESET-ID的CORESET的TCI状态，在被MAC-CE激活后总是对应于至少两个RS set，每个RS set对应不同的DMRS端口组的TCI状态。
即PDSCH的一个或多个DMRS端口组中的天线端口分别和最近的配有一个或多个CORESETs的时隙中的用于PDCCH QCL指示的具有最低CORESET-ID的CORESET的TCI状态的一个或多个参考信号集合中的参考信号是QCL的。例如，第一个DMRS端口组中的天线端口和最近的配有一个或多个CORESETs的时隙中的用于PDCCH QCL指示的具有最低CORESET-ID的CORESET的TCI状态的第一个参考信号集合中的参考信号是QCL的；第二个DMRS端口组中的天线端口和最近的配有一个或多个CORESETs的时隙中的用于PDCCH QCL指示的具有最低CORESET-ID的CORESET的TCI状态的第二个参考信号集合中的参考信号是QCL的；以此类推。
再例如，所述一个或多个参考信号集合是具有最低CORESET-ID的CORESET中的被激活的至少两个TCI状态所对应的至少两个参考信号集合。例如，具有最低CORESET-ID的CORESET的TCI状态，在被MAC-CE激活后至少包含两个。
即PDSCH的一个或多个DMRS端口组中的天线端口分别和最近的配有一个或多个CORESETs的时隙中的用于PDCCH QCL指示的具有最低CORESET-ID的CORESET的一个或多个TCI状态中的参考信号(集合)是QCL的。例如，第一个DMRS端口组中的天线端口和最近的配有一个或多个CORESETs的时隙中用于PDCCH QCL指示的具有最低CORESET-ID的CORESET的第一个TCI状态中的参考信号(集合)是QCL的；第二个DMRS端口组中的天线端口和最近的配有一个或多个CORESETs的时隙中的用于PDCCH QCL指示的具有最低CORESET-ID的CORESET的第二个TCI状态中的参考信号(集合)是QCL的；以此类推。
再例如，所述一个或多个参考信号集合是至少两个CORESET中的被配置为默认的TCI状态所对应的至少两个参考信号集合。例如，可以同时配置两个或两个以上CORESET的TCI状态作为默认TCI状态，即同时配置两个或两个以上CORESET ID，且配置的多个CORESET的TCI状态同时生效。
即PDSCH的一个或多个DMRS端口组中的天线端口分别和最近的配有一个或多个CORESETs的时隙中的用于PDCCH QCL指示的具有一个或多个CORESET的TCI状态中的参考信号(集合)是QCL的。例如，第一个DMRS端口组中的天线端口和 最近的配有一个或多个CORESETs的时隙中的用于PDCCH QCL指示的具有最低CORESET-ID的CORESET的TCI状态的参考信号(集合)是QCL的；第二个DMRS端口组中的天线端口和最近的配有一个或多个CORESETs的时隙中的用于PDCCH QCL指示的具有次低CORESET-ID的CORESET的TCI状态的参考信号(集合)是QCL的；以此类推。
值得注意的是，以上各个实例仅对本发明进行了示意性说明，与DMRS端口组中的天线端口QCL的CORESET的编号不限于此，例如可以是最低CORESET-ID，次低CORESET-ID等，本发明不对此进行限制。
由此，在接收到DCI的时刻和对应的PDSCH之间的时间偏移小于预设门限的情况下，所述PDSCH的至少两个DMRS端口组被分别配置或预定义默认的TCI状态；在多TRP场景中，时间偏移小于门限的情况下，能够避免终端设备只能接收一个TRP发过来的PDSCH的情况。
在一个实施方式中，在终端设备被配置成与多个传输点进行信号传输的情况下，不期望用于发送所述DCI的控制资源集合的指示动态TCI状态的参数(例如TCI-PresentInDCI)是非使能的。本实施方式针对图2的C部分所示的情况。
例如，在多TRP场景下，PDCCH与其调度的PDSCH可能被不同的TRP/cell发送，若PDCCH发送时使用的CORESET的TCI-PresentInDCI被设置为非使能状态，当时间偏移大于门限时，终端设备会默认PDSCH的TCI状态与传输PDCCH的CORESET的TCI状态时一致；而此时PDSCH可能是由另一个TRP发送的，其TCI状态与PDCCH的TCI状态是不相同的。
在本实施方式中，终端设备不期望用于发送所述DCI的控制资源集合的指示动态TCI状态的参数(例如TCI-PresentInDCI)是disabled的。
例如，终端设备不期望用于发送DCI的多个(例如所有的)控制资源集合的指示动态TCI的参数均是非使能的。
再例如，在多TRP场景下，如果一个DCI包含多个PDSCH的调度许可时，该DCI可以包含多个TCI字段(field)。
在本实施方式中，终端设备在发送DCI的控制资源集合的用于指示动态TCI状态的参数(例如TCI-PresentInDCI)非使能的情况下，还可以从所述DCI中获取默认的TCI状态。其中，一个或多个默认的TCI状态可以通过网络设备发送的信令而被 配置，和/或，所述一个或多个默认的TCI状态也可以被预先定义。
例如，因为本实施方式中默认TCI状态为上述门限之后的默认状态，此时该DCI已经可以被成功译码，因而可以使用DCI对默认的TCI状态进行指示。即，当承载DCI的CORESET的TCI-PresentInDCI为非使能状态时，可以使用DCI对默认的TCI状态进行指示。
例如，可以使用RRC信令配置多种默认状态，例如包括：与单点传输时一样的默认状态(调度PDSCH的CORESET的TCI状态)，以及其它一种或以上的TCI状态(如PDSCH的一个或多个DMRS端口组中的天线端口和CORESET ID为i的CORESET的TCI状态是QCL的)；可以再使用DCI为终端设备指示当前DCI调度的PDSCH的默认TCI状态为RRC信令配置的哪种默认TCI状态。
再例如，仍然使用RRC加上DCI的方式进行指示，但是可以不必配置与单点传输时一样的默认状态，因为该状态也是对应某个CORESET的TCI状态。因而RRC中可以配置一个或以上CORESET的TCI状态作为PDSCH的默认TCI状态。例如，当前时隙配置的CORESETs的ID分别为i，j和k，因而RRC信令配置的默认TCI状态为：PDSCH的一个或多个DMRS端口组中的天线端口和CORESET ID为i的CORESET的TCI状态是QCL的；PDSCH的一个或多个DMRS端口组中的天线端口和CORESET ID为j的CORESET的TCI状态是QCL的；PDSCH的一个或多个DMRS端口组中的天线端口和CORESET ID为k的CORESET的TCI状态是QCL的，等等。
再例如，可以在协议中预定义多种默认的TCI状态，例如当前时隙(slot)配置的所有CORESET的TCI状态均可以作为候选的默认TCI状态，因此只需使用DCI进行指示即可。
由此，即使在多TRP场景下，PDCCH与其调度的PDSCH可能被不同的TRP/cell发送，终端设备也能够正确地接收到多TRP发送的传输信息。
在一个实施方式中，在多TRP场景下，非相干联合传输(NC-JT，non-coherent joint transmission)和动态点选择(DPS，Dynamic Point Selection)会动态地切换，从终端设备的角度，需要正确地确定当前的TCI状态和/或QCL参数以正确接收多个TRP/天线面板/cell发来的信号。
例如，终端设备可以确定PDSCH的一个或多个DM-RS端口组的至少两个TCI状态是有效的。其中，至少两个有效的TCI状态可以包括：根据指示信息被激活的 TCI状态，和/或，默认的TCI状态。例如，可以包括一个根据指示信息激活的TCI状态和一个默认的TCI状态，也可以包括两个根据指示信息激活的TCI状态，也可以包括两个默认的TCI状态。
例如，至少两个TCI状态可以来自多个TRP/天线面板/cell，即不管当前传输方法是NC-JT还是DPS，终端设备总是假设来自多个TRP/天线面板/cell的波束指示或默认的QCL参数都是有效的。
再例如，终端设备在第n个时隙接收所述网络设备发送的指示第n+k个时隙的调度信息；以及根据所述调度信息在第n+k个时隙确定所述TCI状态或传输方案。n为大于或等于0的整数，k为大于或等于1的整数。
即，可以假设前k个时隙(slot)会指示当前slot的调度情况，例如在slot n-k中指示slot n的PDSCH传输会包含DMRS端口组1，或者DMRS端口组2，或同时使用DMRS端口组1和2；当DMRS端口组的最大数大于2时，相应的指示字段也相应地增大。即，可以允许有k个slot的调度延时。由此，终端设备无需假设多个TRP发过来的波束同时生效，尤其是在DPS操作下，能够进一步节省终端设备的能量消耗。
值得注意的是，以上各个实施方式仅对本发明实施例进行了示例性说明，但本发明不限于此，还可以在以上各个实施方式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方式，也可以将以上各个实施方式中的一种或多种结合起来。
由上述实施例可知，接收端为一个或多个DMRS端口组配置或预定义一个或多个TCI状态；由此，即使是在例如多TRP或多panel的场景下，接收端也能正确及时地接收到发送端发送的传输信息。

例如，所述一个或多个参考信号集合可以是具有最低控制资源集合标识的控制资源集合中的被激活的一个TCI状态所对应的至少两个参考信号集合；或者是具有最低控制资源集合标识的控制资源集合中的被激活的至少两个TCI状态所对应的至少两个参考信号集合；或者是至少两个控制资源集合中的被配置为默认的TCI状态所对应的至少两个参考信号集合。
在一个实施方式中，在终端设备被配置成与多个传输点进行信号传输的情况下，网络设备确定用于发送所述DCI的控制资源集合的指示动态TCI状态的参数不是非使能的。
