Description

传输配置指示的发送和接收方法、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，特别涉及一种传输配置指示(TCI，Transmission Configuration Indication)的发送和接收方法、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，3rd 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。
发明内容
发明人发现：在基站获得UE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支持基站将使用的发送端波束指示给UE，便于UE决定采用哪个接收端波束进行对齐接收。
但是，对于如何发送和接收波束指示或者如何进行波束指示状态的更新，目前并没有解决方案。值得注意的是，本发明实施例中的波束指示可以称为空间准共址(QCL，Quasi-Co-Location)指示，或者也可作为传输配置指示(TCI，Transmission Configuration Indication)的参数或部分配置来指示。

接收单元，其接收网络设备发送的用于触发用户设备进行传输配置指示状态更新的命令；以及
发送单元，其将更新后的一个或多个传输配置指示的状态信息反馈给所述网络设备，和/或，将用于指示所述一个或多个传输配置指示的状态是否变化的指示信息反馈 给所述网络设备。

发送单元，其向用户设备发送用于触发所述用户设备进行传输配置指示状态更新的命令；以及
接收单元，其接收所述用户设备反馈的指示一个或多个传输配置指示的状态是否变化的指示信息，和/或，所述用户设备反馈的更新后的一个或多个传输配置指示的状态信息。
根据本发明实施例的第五个方面，提供一种通信系统，包括：
网络设备，其包括如上第四方面所述的传输配置指示的发送装置；
用户设备，其包括如上第二方面所述的传输配置指示的接收装置。
本发明实施例的有益效果在于：用户设备接收网络设备发送的用于触发该用户设备进行传输配置指示状态更新的命令；以及反馈更新后的一个或多个传输配置指示的状态信息，和/或，反馈用于指示一个或多个传输配置指示的状态是否变化的指示信息。由此，网络设备和用户设备可以对传输配置指示的状态达成一致，能够准确地进行基于波束的信息传输。

实施例1
本发明实施例提供一种传输配置指示的接收方法，应用于用户设备侧。
图2是本发明实施例的传输配置指示的接收方法的一示意图，从用户设备侧进行 说明。如图2所示，所述方法包括：
步骤201，用户设备接收网络设备发送的用于触发所述用户设备进行传输配置指示状态更新的命令；以及
步骤202，用户设备将更新后的一个或多个传输配置指示的状态信息反馈给所述网络设备，和/或，将用于指示所述一个或多个传输配置指示的状态是否变化的指示信息反馈给网络设备。
在本实施例中，用户设备还可以接收网络设备发送的多个传输配置指示的配置信息，和/或，接收所述网络设备发送的一个或多个传输配置指示的更新信息。
例如，网络设备可以将M个候选TCI状态通知给用户设备，和/或，将一个或多个候选TCI状态更新给用户设备。例如，网络设备既可以针对之前的TCI状态对当前TCI状态进行更新，例如使用RRC信令或MAC CE或DCI；也可以每隔一段时间将所有的M个TCI状态指示给用户设备，例如使用RRC信令。
此外，关于TCI的具体内容，可以参考相关技术，此处不再赘述。
在本实施例中，所述传输配置指示的更新信息可以包括如下信息的一种或多种：所述传输配置指示的状态数目、增加或减少的发送端波束对应的参考信号标识(ID)信息、增加或减少的发送端波束对应的传输配置指示状态的编号、增加或减少的发送端波束对应的参考信号ID信息的集合、增加或减少的发送端波束对应的传输配置指示状态的集合、增加或减少的发送端波束对应的参考信号标识信息的集合编号。
但本发明不限于此，例如还可以包括其他的信息。参考信号ID信息通常对应波束的编号信息，例如CSI-RS的ID，CSI-RS的资源指示(CSI-RS resource indication，CRI)的编号或SSB(SS Block)的编号。
例如，网络设备在进行TCI状态更新时，可以仅包含增加的或减掉的发送端波束对应的参考信号ID信息，而不包含其对应的TCI状态编号；或者，也可以既包含增加的或减掉的TCI状态编号，也包含增加的或减掉的发送端波束对应的参考信号ID信息；或者，为减少网络设备和用户设备之间的错误解读，在对TCI状态进行更新时，还可以每次仅增加或减掉一个发送端波束。
在本实施例中，所述传输配置指示的状态信息包括如下信息的一种或多种：
所述传输配置指示的状态数目、传输配置指示状态的编号、发送端波束对应的参考信号ID信息、增加或减少的发送端波束对应的参考信号ID信息、增加或减少的发 送端波束对应的传输配置指示状态的编号、增加或减少的发送端波束对应的参考信号ID信息的集合、增加或减少的发送端波束对应的传输配置指示状态的集合、增加或减少的发送端波束对应的参考信号标识信息的集合编号。
在本实施例中，网络设备可以显式地或者隐式地发送用于触发所述用户设备进行传输配置指示状态更新的命令。该命令可以是包含在DCI中的触发信息，也可以是其他的触发信息；以下将进行进一步说明。
图3是本发明实施例的传输配置指示的发送和接收方法的一示意图，从用户设备侧和网络设备侧进行说明。如图3所示，所述方法可以包括：
步骤301，网络设备发送多个传输配置指示的初始配置信息，和/或，发送一个或多个传输配置指示的更新信息；
在本实施例中，网络设备可以隐式地触发用户设备进行传输配置指示状态更新。例如，每当网络设备通知或更新TCI状态时，均会隐式地触发用户设备来上报是否对当前TCI状态进行更新。但本发明不限于此，还可以如后面实施例所述地，显式地触发用户设备进行传输配置指示状态更新。
步骤302，用户设备根据所述配置信息和/或所述更新信息以及预存的多个传输配置指示的当前状态，对一个或多个传输配置指示进行更新；
在本实施例中，用户设备可以根据所述配置信息和/或所述更新信息，预存的多个传输配置指示的当前状态以及波束测量的结果，增加和/或合并所述多个传输配置指示的状态。
例如，经过波束管理过程(P1，P2和P3)以后，用户设备可以获得质量较优的收发端波束对的关联信息，并可以通过波束上报将质量较优的发送端波束编号和/或相应的RSRP上报给基站。基站虽然可以知道质量较优的发送端波束编号，但并不知道其对应的接收端波束编号。从用户设备的角度看，基站发送的一个或多个状态所对应的发送端波束可能对应相同的接收端波束，因此，从指示用户设备确定接收端波束的角度来看，所述的多个TCI的状态是可以合并的。
同理，TCI的状态也是可以增加的。此外，也可以将一个或多个质量较优的发送端波束添加到当前的某个TCI状态上，或者将一个或多个质量稍差的发送端波束从对应的TCI状态上去除。
例如，用户设备的TCI的当前状态可以包括6个。在接收到网络设备发送的更新 信息之后，用户设备可以合并其中的一些状态；从而将TCI的状态更新为4个；或者在接收到网络设备发送的更新信息之后，用户设备可以增加新的一些状态；从而将TCI的状态更新为8个；或者在接收到网络设备发送的更新信息之后，用户设备将一个或多个发送端波束添加到当前的某个TCI状态上；或者在接收到网络设备发送的更新信息之后，用户设备将一个或多个发送端波束从对应的TCI状态上去除。
步骤303，用户设备将更新的TCI的状态信息反馈给所述网络设备。
例如，用户设备将希望增加的波束编号(例如，CSI-RS ID，SSB ID)及推荐的传输配置指示状态的编号发送给网络设备。也可以将希望减掉的波束编号(例如，CSI-RS ID，SSB ID)及网络设备为该波束配置的传输配置指示状态的编号发送给网络设备。可以使用上行控制信息来发送该更新信息。
在本实施例中，在用户设备对所述多个传输配置指示进行更新后，可以直接将更新后的多个TCI的状态信息反馈给所述网络设备；网络设备还可以根据所述状态信息对多个传输配置指示进行更新以示用户设备的更新生效。由此，网络设备和用户设备能够对传输配置指示的状态达成一致，能够准确地进行基于波束的信息传输。
在本实施例中，网络设备还可以使用触发信息，来触发用户设备上报对TCI的状态信息进行更新及上报。
图4是本发明实施例的传输配置指示的发送和接收方法的另一示意图，从用户设备侧和网络设备侧进行说明；其中与图3的说明相同的内容不再赘述。如图4所示，所述方法可以包括：
步骤401，网络设备发送多个传输配置指示的配置信息，和/或，发送一个或多个传输配置指示的更新信息；
例如，网络设备在进行TCI状态更新时，可以仅包含增加的或减掉的发送端波束编号，而不包含其对应的TCI状态编号；或者，也可以既包含增加或减掉的TCI状态编号，也包含增加的或减掉的发送端波束编号；或者，为减少网络设备和用户设备之间的错误解读，在对TCI状态进行更新时，还可以每次仅增加或减掉一个发送端波束的集合。
步骤402，网络设备发送用于触发用户设备上报是否对多个TCI进行更新的第一触发信息；即，网络设备触发用户设备对所述传输配置指示进行更新的命令。
在一个实施方式中，所述第一触发信息可以通过DCI显式地被承载。例如，使用 DCI中一个控制区域来直接触发用户设备来上报是否对当前TCI状态进行更新。
例如，DCI某个format中使用1比特(bit)来触发用户设备来上报是否对当前TCI状态进行更新。当该比特被置为1时，表示网络设备触发用户设备来上报是否对当前TCI状态进行更新。当该比特置为0时，表示网络设备没有触发用户设备来上报是否对当前TCI状态进行更新。
在另一个实施方式中，所述第一触发信息可以通过所述更新信息隐式地被承载。
例如，每当网络设备通知或更新TCI状态时(即步骤401执行时)，均会隐式地触发用户设备来上报是否对当前TCI状态进行更新。在这种情况下，步骤402可以省略。
在另一个实施方式中，所述第一触发信息可以与控制信令进行联合编码而被承载。例如，可以与DCI其它控制域的控制信令联合编码。
例如，可以与非周期的CSI-RS发送或非周期的波束上报的触发信息联合编码。例如与非周期的波束上报的触发信息联合进行编码时，状态00可以表示触发用户设备来上报是否对当前TCI状态进行更新；状态01可以表示一种非周期的波束上报模式；状态10可以表示另一种非周期的波束上报模式。
在本实施方式中，不同的模式可以表示波束上报的参数不同。与其它控制信令联合进行编码时，总的比特数可以是1，2，3等等，取决于其它控制信令的状态个数，用于触发UE去上报是否对当前TCI状态进行更新的状态可以仅有一个；也可以有多个。
除此之外，以上各个方法可以和RRC信令联用，即使用RRC信令对此触发功能的开关进行配置。例如，当RRC信令配置该触发功能为“开”时，以上各个方法生效；当RRC信令配置该触发功能为“关”时，以上各个方法均不生效。
在另一个实施方式中，网络设备也可以配置用户设备来周期性地上报是否对当前TCI状态进行更新。即第一触发信息为RRC信令配置的周期性上报配置；但本发明不限于此。
步骤403，用户设备确定一个或多个传输配置指示的状态是否发生变化；
步骤404，用户设备向所述网络设备发送用于指示所述一个或多个传输配置指示的状态是否变化的指示信息。
在本实施例中，所述指示信息可以包括如下信息的一种或多种：表示所述传输配 置指示的状态数量的比特数发生变化的信息，表示所述传输配置指示的状态数量的比特数没有发生变化的信息，表示所述传输配置指示的状态增加的信息，表示所述传输配置指示的状态合并的信息；但本发明不限于此。
例如，假设状态更新后的TCI状态数量为Naf，如果[log2Naf]＞[log2M]，则UE上报“00”,这种情况发生在gNB对TCI状态更新时，且更新的状态不能和当前的其它TCI状态合并。如果[log2Naf]＜[log2M]，则UE上报“01”。如果[log2Naf]＝[log2M]，则UE上报“10”。
在本实施例中，状态“00”，“01”，“10”仅用于示意，但不限于此。
在本实施例中，在表示所述多个传输配置指示的状态数量的比特数没有发生变化的情况下，用户设备可以不进行更新，即TCI状态信息保持原状态，并且暂时不向网络设备反馈TCI的状态信息。
例如，用户设备的TCI的当前状态可以包括6个(使用3比特表示)；在接收到网络设备发送的更新信息之后，用户设备可以增加新的一些状态；从而将TCI的状态更新为8个(仍使用3比特表示)。或者，在接收到网络设备发送的更新信息之后，用户设备可以合并一些状态；从而将TCI的状态更新为5个(仍使用3比特表示)。则表示所述多个TCI的状态数量的比特数没有发生变化，用户设备可以不再向网络设备反馈TCI的状态信息，并且用户设备侧的TCI状态信息保持原状态，即不进行更新。
由此，网络设备和用户设备能够对传输配置指示的状态保持一致，能够准确地进行基于波束的信息传输。
在本实施例中，网络设备还可以使用触发信息，来触发用户设备上报更新后的TCI的状态信息。此外，网络设备对多个传输配置指示进行更新可以通过RRC信令或MAC CE来完成。
图5是本发明实施例的传输配置指示的发送和接收方法的另一示意图，从用户设备侧和网络设备侧进行说明；其中与图3和4的说明相同的内容不再赘述。如图5所示，所述方法可以包括：
步骤501，网络设备发送多个传输配置指示的配置信息，和/或，发送一个或多个传输配置指示的更新信息；
步骤502，网络设备发送用于触发用户设备上报是否对多个TCI进行更新的第一触发信息；
步骤503，用户设备确定所述一个或多个传输配置指示的状态是否发生变化；
步骤504，用户设备向所述网络设备发送指示所述一个或多个传输配置指示的状态是否变化的指示信息。
再例如，假设状态更新后的TCI状态数量为Naf，如果[log2Naf]≠[log2M]，则UE上报“1”,即增加TCI状态数和减少TCI状态数均用上报中的同一个状态来表示。如果[log2Naf]＝[log2M]，则UE上报“0”。
再例如，假设状态更新后的TCI状态数量为Naf，如果[log2Naf]≤[log2M]或者Naf≤M，则UE上报“1”,即可以对TCI状态数进行合并。否则，则UE上报“0”。
值得注意的是，以上仅对指示信息的内容和发送时机进行了示例性说明，但本发明不限于此，可以根据实际需要确定具体的内容或形式。
步骤505，用户设备根据所述配置信息和/或所述更新信息以及预存的多个传输配置指示的当前状态，对一个或多个传输配置指示进行更新；
在本实施例中，用户设备可以根据所述配置信息、所述更新信息和波束测量的结果的一种或多种，以及预存的多个传输配置指示的当前状态，更新(例如可以包括：增加和/或合并和/或减掉和/或拆分，即可以是这四种操作的一种或多种)所述多个传输配置指示的状态。此外，还可以增加和/或合并和/或减掉和/或拆分所述一个或多个发送端波束对应的参考信号标识信息。
在本实施例中，在表示所述多个传输配置指示的状态数量的比特数发生变化的情况下，用户设备可以向网络设备反馈TCI的状态信息。
例如，用户设备的TCI的当前状态可以包括6个(使用3比特表示)；在接收到网络设备发送的更新信息之后，用户设备可以增加新的一些状态；从而将TCI的状态更新为9个(使用4比特表示)。或者，在接收到网络设备发送的更新信息之后，用户设备可以合并一些状态；从而将TCI的状态更新为4个(使用2比特表示)。则表示所述多个TCI的状态数量的比特数发生变化，用户设备可以向网络设备反馈TCI的状态信息。
步骤506，网络设备发送用于触发用户设备上报更新后的所述多个传输配置指示 的第二触发信息；
例如，如果UE上报了“00”或“01”状态，网络设备会进一步触发UE上报更新的TCI状态信息。或者，如果步骤504中UE的上报为“0”或“1”，且UE上报的状态为“1”时，网络设备会进一步触发UE上报更新的TCI状态。
其中，触发时使用的状态可以是一个或多个，例如，可以使用一个状态来表示触发UE上报更新的TCI状态；也可以使用多个状态来表示触发的多种上报形式。
在本实施例中，所述第二触发信息可以通过DCI被显式地承载，或者也可以通过与波束非周期性上报的触发信息进行联合编码而被承载。例如状态“0”用于触发波束编号及RSRP上报，状态“1”用于触发TCI状态更新上报。或者在非周期波束上报有多个状态时，也可以使用控制区域的2bit，3bit设置更多比特对触发UE上报更新的TCI状态和触发UE进行非周期波束上报进行联合编码，且触发UE上报更新的TCI状态占据其中的一个或多个状态。
或者，所述第二触发信息也可以被配置为周期性地发送。
步骤507，用户设备将更新的传输配置指示的状态信息反馈给网络设备。
例如，具体上报内容可以包括：更新后的TCI状态数，和/或，新TCI状态编号1以及相应的发送端波束编号，新TCI状态编号2以及相应的发送端波束编号，新TCI状态编号3以及相应的发送端波束编号......。
或者，具体上报内容还可以是：仅包含增加的TCI状态编号；或者，仅包含增加的发送端波束对应TCI状态编号，可能是原有的TCI状态编号；或者，包含增加的一个或多个TCI状态编号，及每个新增状态对应的发送端波束编号；或者，仅包含减掉的TCI状态编号；或者，包含减掉的一个或多个TCI状态编号，及每个减掉的TCI状态对应的发送端波束编号对应的新TCI状态编号。
步骤508，网络设备发送所述更新后的多个传输配置指示的确认信息。
在本实施例中，网络设备还可以对用户设备的更新结果进行确认，并且网络设备还可以根据所述状态信息对多个传输配置指示进行更新，则更新的新TCI状态表可以在网络设备侧和用户设备侧均生效。该确认信息可以使用DCI信令来传输，例如1bit即可。该确认信息也可以使用RRC信令或MAC CE来传输。
由此，网络设备和用户设备能够对传输配置指示的状态达成一致，能够准确地进行基于波束的信息传输。此外，使用DCI进行波束指示时，可以根据状态数对控制信 令比特数进行调整，能够降低指示信令的开销。
值得注意的是，以上附图3-5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3-5的记载。
由上述实施例可知，用户设备接收网络设备发送的用于触发该用户设备进行传输配置指示状态更新的命令；以及反馈更新后的一个或多个传输配置指示的状态信息，和/或，反馈用于指示一个或多个传输配置指示的状态是否变化的指示信息。由此，网络设备和用户设备能够对传输配置指示的状态达成一致，能够准确地进行基于波束的信息传输。
