Description

信息传输的方法及设备
本申请要求在2018年09月28日提交中国专利局、申请号为201811142057.X的中国专利申请的优先权，该申请的全部内容通过引用结合在本申请中。
技术领域
本发明实施例涉及但不限于无线通信技术，更具体的涉及一种信息传输的方法及相关设备。
背景技术
在无线通信系统中，发送端和接收端一般会采用多根天线发送和接收来获取更高的速率。多输入多输出(multiple-input-multiple-output，MIMO)技术的一个原理是利用信道的一些特征来形成匹配信道特征的多层传输，从而能够有效的提升系统性能，在不增加带宽和功率的基础上就获得显著的性能提升，是一个非常有前景的技术，在系统中广泛应用。
发送端发送参考信号，接收端通过对接收到的参考信号的测量，计算得到CSI(Channel State Information，信道状态信息)，并通过信道将CSI反馈给发送端，以进行匹配信道特征的预编码或波束赋型传输。为了指示传输信息，基站将参考信号的标识(Identifier，ID)作为QCL(Quasi-co-location，准共位置)源配置在每个TCI(Transmission configuration Indication，传输配置指示)的配置中，并为终端(UE，User equipment)(也称为用户设备)配置一个TCI集合作为传输参数的候选集合。所述参考信号可能是周期、半持续或非周期的参考信号，对于半持续或非周期的参考信号，基站会通过信令触发或激活该参考信号的传输。基站在每次调度数据信息传输时，通过信令通知终端从候选TCI集合或其子集中挑选出来的TCI，以使得终端根据TCI指示的传输参数来进行数据信息的接收。通常来说，触发非周期或半持续参考信号传输的信令和指示TCI的信令并不是同一个信令。另外，由于非周期或半持续的参考信号可以在不同时间多次触发，终端对于TCI指示的传输参数的理解需要明确。此外，在接收到触发非周期或半持续参考信号的信令，或接收到指示TCI的信令，或接收到非周期或半持续参考信号之后，终端需要一定的时间来对这些信息进行处理，以进行正确的数据信息接收。
因此，为了满足终端处理时间的需求，并且提升TCI指示的灵活性和有效性，需要对TCI指示的信令、触发上述参考信号的信令、参考信号的传输、TCI关联的数据信息的传输之间的时序关系进行较为清晰的定义。相关技术中，并 没有清晰定义出上述的时序关系，终端存在理解模糊或处理时间不够的问题。

附图说明

具体实施方式
下文中将结合附图对本申请的实施例进行详细说明。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互任意组合。
在附图的流程图示出的步骤可以在诸如一组计算机可执行指令的计算机系统中执行。并且，虽然在流程图中示出了逻辑顺序，但是在某些情况下，可以以不同于此处的顺序执行所示出或描述的步骤。
MIMO无线通信中，基站会使用指示传输配置指示的方式来提升信息传输的性能。具体来说，基站配置传输配置指示的候选取值集合，在每次调度信息传输的时候，可以通过信令通知终端从候选取值集合或其子集中选出的传输配置指示，以使得终端根据基站指示的传输配置指示来进行信息的接收。通常，不同的传输配置指示表示了不同的信道特性，基站指示匹配信道特性的传输配置指示，终端可以进行匹配信道特性的信息接收，可以提升信息传输和接收的性能。一个传输配置指示包含了至少一个作为QCL源信息的参考信号资源ID信息，而该参考信号资源ID可以表示周期、非周期、半持续的参考信号资源。指示TCI的信令和触发(或激活)参考信号资源ID的信令通常并不是同一个信令。此外，接收指示TCI的信令之后，终端通常需要一定时间来进行处理，才能正确接收TCI对应的数据或控制信息传输。这样，为了满足终端处理时间的需求，并且提升TCI指示的灵活性和效率，需要对TCI状态指示的信令、触发上述参考信号的信令、参考信号的传输、TCI关联的数据或控制信息的传输之间的时序关系进行较为清晰的定义。为此，本发明实施例提供了一种信息传输的技术方案，能够清晰定义出TCI状态指示的信令、触发参考信号的信令、参考信号的传输、TCI关联的数据或控制信息的传输中至少之二的时序关系，避免终端存在理解模糊或处理时间不够的问题。

下面通过五个具体的示例详细阐述上述实施例一、二提供的技术方案。
示例一
图3是本申请示例一提供的信息传输的方法的流程示意图，如图3所示，该方法包括：
步骤301，基站发送第一下行控制信息(Downlink Control Information，DCI)和第二DCI，所述第一DCI用于指示TCI状态信息，所述第二DCI用于触发非周期(Aperiodic，AP)信道状态信息参考信号(Channel State Information-Reference Signal，CSI-RS)。
其中，本示例一中，信令的形式可以为DCI信令。即，本示例中第一信令和第二信令分别为第一DCI和第二DCI。
其中，基站为终端指示的TCI状态信息中，表示QCL参数的参考信号可以是非周期CSI-RS(即第一参考信号)。对于非周期CSI-RS，其QCL信息可以通过触发该CSI-RS的DCI信令指示。
具体来说，对于某一非周期CSI-RS资源(resource)，包含该CSI-RS的触发状态可以配置不同的QCL参数信息，表1给出了这种配置的一个例子。
表1：CSI-RS触发状态配置
Figure PCTCN2019107039-appb-000001
如表1所示，不同CSI触发状态关联到不同的DCI状态位。例如，DCI中CSI请求域中，如果指示为01，则触发TS 1对应的参考信号资源集合，如果指示为10，则触发TS 2对应的参考信号资源集合。另外，TS 1和TS 2中包含同一CSI-RS资源AP CSI-RS资源0，但对应的QCL信息不一样。在TS 1中配置的CSI-RS资源0的QCL源是CSI-RS资源1，而在TS 2中配置的CSI-RS资源0的QCL源是CSI-RS资源2。因此，AP CSI-RS的QCL参数可以通过触发该CSI-RS的DCI来改变。另一方面，基站在调度数据传输时，调度数据的DCI可以指示数据传输的TCI信息，而TCI中包含的QCL信息可以是AP CSI-RS，而终端在通过AP CSI-RS获取对应的QCL信息时，需要通过该AP CSI-RS对应的QCL信息来获取最终的QCL信道参数。将指示数据TCI信息的DCI称为第一DCI，将触发AP CSI-RS的DCI称为第二DCI。
步骤302，终端接收所述第一DCI和所述第二DCI。
步骤303，终端根据所述第一DCI确定调度的数据信道，第一DCI调度的数据信道使用第一DCI之前最近一次传输的AP CSI-RS资源对应的QCL信息。
其中，第一DCI指示的TCI为AP CSI-RS资源时，第一DCI调度的数据信道使用第一DCI之前最近一次传输的AP CSI-RS资源对应的QCL信息。从另一方面说，即第一DCI调度的数据信道DMRS(Demodulation reference signal，解调参考信号)和第一DCI之前最近一次传输的该AP CSI-RS是QCL的。
在另一个可能的例子中，终端可以自行决定使用第一DCI之前某一次传输的AP CSI-RS资源对应的QCL信息，而不局限于最近一次。
如图4所示，本示例一中，能够确保AP CSI-RS在第一DCI之前传输，而“最近一次”可以让终端正确理解AP CSI-RS对应的QCL信息，且能够使用最新的AP CSI-RS传输来更新QCL信息。
可选地，如果第一DCI之前最近一次传输的AP CSI-RS资源的触发时延大于或等于阈值K，那么第一DCI调度的数据信道使用所述第一DCI之前最近一次传输中AP CSI-RS资源的QCL信息；如果第一DCI之前最近一次传输的AP  CSI-RS的触发时延小于上述阈值K，且第一DCI调度的数据信道的第一个符号到第二DCI的符号个数大于K，则第一DCI调度的数据信道使用第二DCI指示的AP CSI-RS的QCL信息。
其中，所述AP CSI-RS资源的触发时延为第二DCI到所述AP CSI-RS之间的时域符号个数。
其中，所述阈值K为基站配置的阈值或根据UE能力确定的阈值，例如，K是表示为了应用DCI通知的TCI状态，终端需要的从DCI到应用该TCI状态的信道或信号之间的时域符号个数。
可选地，所述第一DCI和所述第一DCI之前最近一次传输的AP CSI-RS之间至少间隔M1个时域符号。
其中，所述M1的取值可以根据预设的规则确定，例如是一个固定的值；或者，根据终端的能力确定，例如，根据上述阈值K确定；或者，根据终端在一个时隙内可以切换波束的次数确定，例如，如果该次数为B，则M1的取值至少大于或等于
Figure PCTCN2019107039-appb-000002
其中，
Figure PCTCN2019107039-appb-000003
表示一个时隙内的时域符号个数，例如为14；或者，M1的取值根据终端所需要的从CSI-RS到CRI(CSI-RS resource indication，CSI-RS资源指示)/L1-RSRP(Layer-1reference signal receive power，L1-参考信号接收功率)上报所需的符号个数确定。
可选地，所述第一DCI调度的数据信道和所述第一DCI之前最近一次传输的AP CSI-RS之间至少间隔M2个符号。
其中，所述M2的取值可以根据预设的规则确定，例如是一个固定的值；或者，根据终端的能力确定，例如，根据上述阈值K确定，具体的，该取值为K，或者该取值为K加上某一预设值或终端能力值；或者，根据终端在一个时隙内可以切换波束的次数确定，例如，如果该次数为B，则M2的取值至少大于或等于
Figure PCTCN2019107039-appb-000004
其中，
Figure PCTCN2019107039-appb-000005
表示一个时隙内的时域符号个数，例如为14；或者，M2的取值根据终端所需要的从CSI-RS到CRI/L1-RSRP上报所需的符号个数确定；或者，根据第一DCI中TCI包含的QCL类别确定，例如，如果QCL类别包括空间接收参数，则M2的取值为第一预定值或第一终端能力值，如果QCL类别不包括空间接收参数，则M2的取值为第二预定值或第二终端能力值。
可选地，第一DCI和第二DCI来自同一个服务小区。
可选地，第一DCI、第二DCI与第一DCI调度的数据信道处于同一个服务小区。
可选地，第一DCI、第二DCI、第二DCI触发的AP CSI-RS与第一DCI调度的数据信道处于同一个服务小区。
可选地，当第一DCI、第二DCI、第二DCI触发的AP CSI-RS与第一DCI调度的数据信道中有至少两者来自不同的服务小区时，对应的CSI-RS、数据信道和/或控制信道对应的子载波间隔相同。
可选地，如果第一DCI和第二DCI来自不同的服务小区，所需M1或M2的取值不同于第一DCI和第二DCI来自同一个的服务小区时，所需M1或M2的取值。
其中，上述服务小区，亦可称为CC(Component Carrier，成分载波)。
示例二
本示例二中，第一DCI、第二DCI的定义如示例一中所述。
本示例二与示例一的不同在于，第一DCI指示的TCI状态为AP CSI-RS资源时，第一DCI调度的数据信道使用第一符号之前的最近一次传输的AP CSI-RS对应的QCL信息。从另一方面说，即第一DCI调度的数据信道DMRS和第一符号之前最近一次传输的该AP CSI-RS是QCL的。
其中，所述第一符号可以是以下方式之一：
方式一：第一DCI调度的数据信道之前第N1个符号为第一符号。换一种说法，即如果第一DCI调度的数据信道第一个符号为符号n，那么第一符号为符号n-N1。
方式二：第一DCI的第一个符号为第一符号。
方式三：第一DCI前的第N2个符号为第一符号。换一种说法，即如果第一DCI的第一个符号为符号n，那么第一符号为符号n-N2。
其中，方式二中，当所述第一符号为第一DCI的第一个符号时，即为示例一中所述的第一DCI调度的数据信道使用第一DCI之前最近一次传输的AP CSI-RS资源对应的QCL信息。
其中，方式一的一个示例如图5所示。对于方式一和方式三，终端在应用AP CSI-RS对应的QCL信息时，留N1或N2个符号有助于终端对AP CSI-RS进行一定的处理之后，在利用对应的信道特征来用于数据信息的接收，可以提高数据接收的性能，且减少终端的复杂度。相比方式二，AP CSI-RS的传输位置限制更小，灵活性更高。
在另一个可能的例子中，终端自行决定使用第一符号之前某一次传输的AP CSI-RS资源对应的QCL信息，而不局限于最近一次。
可选地，如果第一符号之前最近一次传输的AP CSI-RS资源的触发时延大于或等于阈值K，则第一DCI调度的数据信道使用所述第一符号之前最近一次 传输中AP CSI-RS资源的QCL信息。如果第一符号之前最近一次传输的AP CSI-RS的触发时延小于上述阈值K，且第一DCI调度的数据信道的第一个符号到第二DCI的符号个数大于K，则第一DCI调度的数据信道使用第二DCI指示的AP CSI-RS的QCL信息。

方式A3：N1的取值根据终端的能力信息确定。例如，终端上报所需要的从第一符号之前的最近一次AP CSI-RS传输到第一DCI调度的数据信道之间的符号个数。
其中，所述N1的取值也可以通过终端上报的其他能力信息确定。
具体来说，N1的取值可以根据第一能力值确定，所述第一能力值为以下能力值之一：
1、根据所述阈值K确定；例如，N1的取值为K，或者K加上某一预设值或终端能力值。
2、根据终端在一个时隙内可以切换波束的次数确定；例如，如果该次数为B，则N1的取值至少大于或等于

可选地，所述N1的取值是所述第一能力值得到的符号个数和另一预设值N4的和。
可选地，所述N1的取值根据第一DCI中TCI包含的QCL类别确定，例如，如果QCL类别包括空间接收参数，则N1的取值为第一预定值或某一终端能力值，如果QCL类别不包括空间接收参数，则N1的取值为第二预定值或某一终端能力值。
其中，对于方式三中所述N2的取值，可以根据以下方式至少之一确定：
方式B1：N2的取值由该CSI-RS资源或其所在CSI-RS资源集合的配置信息确定；例如，N2根据该CSI-RS资源所在CSI-RS资源集合是否配置重复指示参数确定，或者N2根据该CSI-RS所在CSI-RS资源集合中包含的CSI-RS资源个数确定。
方式B2：N2的取值根据预设的方式确定；例如，N2的取值是固定值。
方式B3：N2的取值根据终端的能力信息确定。例如，终端上报所需要的从该次AP CSI-RS传输到第一DCI之间的符号个数。
其中，所述N2的取值也可以通过终端上报的其他能力信息确定。
具体来说，所述N2的取值可以根据第二能力值确定，所述第二能力值为以下能力值之一：
1、根据所述阈值K确定；例如，N2的取值为K，或者K加上某一预设值或终端能力值。
2、根据终端在一个时隙内可以切换波束的次数确定；例如，如果该次数为B，则N2的取值至少大于或等于

其中，上述服务小区，亦可称为CC。

本示例三与示例一的不同在于，第一DCI指示的TCI状态为AP CSI-RS资源时，第一DCI调度的数据信道使用第二符号之前的最近一次触发AP CSI-RS的第二DCI中指示的QCL信息。从另一方面说，即第一DCI调度的数据信道DMRS应用第二符号之前最近一次触发该AP CSI-RS的第二DCI中指示的QCL信息。
其中，所述第二符号可以是以下方式至少之一：

方式三：第一DCI前的第S2个符号为第二符号；换一种说法，即如果第一DCI的第一个符号为符号n，那么第二符号为符号n-S2。

在另一个可能的例子中，终端可以自行决定使用第二符号之前某一次传输的AP CSI-RS资源对应的QCL信息，而不限于最近一次。
其中，对于方式一中所述S1的取值，可以通过以下方式中至少之一确定：

可选地，所述S1的取值根据上述能力信息中之一和另一预设值S4的和确定。
可选地，所述S1的取值根据第一DCI中TCI包含的QCL类别确定，例如，如果QCL类别包括空间接收参数，则S1的取值为某一预定值或某一终端能力值，如果QCL类别不包括空间接收参数，则S1的取值为另一预定值或另一终端能力值。
其中，对于方式三中S2的取值，可以通过以下方式中至少之一确定：

其中，上述服务小区，亦可称为CC。
示例四
本示例四中，第一DCI、第二DCI的定义如示例一中所述。
本示例四与示例一的不同在于，第一DCI指示的TCI状态为AP CSI-RS资源时，第一DCI调度的数据信道所用的QCL信息为第一DCI之前，AP CSI-RS关联的最近一次CSI报告对应的AP CSI-RS的QCL信息。换一种说法，即第一DCI调度的数据信道DMRS，和第一DCI之前用到所述AP CSI-RS的最近一次CSI报告对应的AP CSI-RS是QCL的，如图7所示。
其中，所述CSI报告可以是CRI/L1-RSRP报告，或者是CRI/RI(Rank indicator，秩指示)/PMI(Precoding matrix indicator，预编码指示)/CQI(Channel quality indicator，信道质量指示)报告。
示例五
本示例五中，基站为终端指示的TCI状态信息中，表示QCL参数的参考信号还可以是MAC(Media access control，媒体介入控制)CE(Control element，控制单元)激活的SP(Semi-persistent，半持续)CSI-RS(即第一参考信号)。对于SP CSI-RS，其QCL信息可以通过触发所述SP CSI-RS的MAC信令指示。
与上述示例一至四的不同在于，本示例五中，所述第一DCI中TCI指示的AP CSI-RS可以替换为SP CSI-RS，触发所述AP CSI-RS的第二DCI可以改为激活所述SP CSI-RS的第一MAC信令。做了上述替换之后，就可以用于SP CSI-RS指示为数据信道QCL源的情况。
可选地，本示例五中，所涉及到的符号个数(例如，M1、M2、N1、N2、S1、S2等参数的取值)可以在示例一至四原有符号个数的基础上，加上从承载MAC CE的数据信道对应的HARQ-ACK(Hybrid automatic request and repeat–acknowledge，混合自动请求重传-正确应答)信息到MAC CE对应的激活信令生效的符号个数。
本示例一至五提供的技术方案中，所述N1、S1对应于实施例一中的N1，所述N2、S2对应于实施例一中的N2。
示例六
本示例六，与示例一至五的不同在于，第一DCI除了可以调度数据信道外，还可以调度其他的目标信道或信号，例如第二参考信号(第二CSI-RS)、控制信道等。
在具体实现中，可以将第一DCI的TCI状态中指示了使用第一符号之前最近一次传输的第一参考信号或所述第二信令对应的QCL信息的数据信道，替换为第一DCI的TCI状态中指示了使用第一符号之前最近一次传输的第一参考信号或所述第二信令对应的QCL信息的第二CSI-RS或控制信道。更具体的，对于第二CSI-RS，可以进一步描述为第一DCI触发或第二MAC CE信令激活的CSI-RS。
例如在一个具体的例子中，第一DCI指示的TCI状态为AP CSI-RS资源时，第一DCI调度的第二CSI-RS使用第一符号之前的最近一次传输的AP CSI-RS对应的QCL信息。从另一方面说，即第一DCI调度的第二CSI-RS和第一符号之前最近一次传输的该AP CSI-RS是QCL的。此处，第一DCI为调度第二CSI-RS的DCI。
其中，所述第一符号可以是以下方式之一：
方式一：第一DCI调度的第二CSI-RS之前第N1个符号为第一符号。换一种说法，即如果第一DCI调度的第二CSI-RS的第一个符号为符号n，那么第一符号为符号n-N1。
方式二：第一DCI的第一个符号为第一符号。
方式三：第一DCI前的第N2个符号为第一符号。换一种说法，即如果第一DCI的第一个符号为符号n，那么第一符号为符号n-N2。
在另一个可能的例子中，第一MAC CE指示的TCI状态为AP CSI-RS资源或SP CSI-RS资源时，第一MAC CE应用的控制信道使用第一符号之前的最近一次传输的AP CSI-RS对应的QCL信息。从另一方面说，即第一MAC CE应用的控制信道DMRS和第一符号之前最近一次传输的该AP CSI-RS是QCL的。此处，第一MAC CE为指示控制信道QCL信息的信令。
其中，所述第一符号可以是以下方式之一：
方式一：第一MAC CE应用的控制信道之前第N1个符号为第一符号。换一种说法，即如果第一MAC CE应用的控制信道的第一个符号为符号n，那么第一符号为符号n-N1。
方式二：第一MAC CE生效后的第一个符号为第一符号。
方式三：第一MAC CE生效前的第N2个符号为第一符号。换一种说法，即如果第一MAC CE生效前的第一个符号为符号n，那么第一符号为符号n-N2。
本示例一至六提供的技术方案，简单明确地定义了第一DCI、第二DCI、第一DCI调度的目标信道或信号、第二DCI触发的CSI-RS或这四者中至少之二的时序关系，解决终端理解模糊或处理能力不够的问题。
具体而言，上述实施例中的N1、N2、M1、M2、S1、S2、K等的取值均可以为大于等于1的自然数。
