Description

信息传输方法及装置
本申请要求于2020年04月08日提交中国专利局、申请号为202010276550.1、申请名称为“信息传输方法及装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信技术领域，尤其涉及一种信息传输方法及装置。
背景技术
目前，在多接收发送点(multi-TRP)场景下，存在至少一个基站向同一个终端发送不同的下行控制信息(Downlink control information，DCI)，终端接收到DCI之后，需要确定至少一个传输指示信息(Transmission configuration indication，TCI)，进而根据至少一个TCI向至少一个基站发送对应的上行信道。
在相关技术中，例如终端接收到一个基站发送的DCI 0_0指示该终端向其中一个基站发送的物理上行共享信道(Physical Uplink Sharing Channel，PUSCH)，通过高层信令可以确定出两个TCI，从而使得中终端无法确定根据两个TCI中的哪一个TCI向该基站发送上行信道，导致终端和基站之间的通信失败。例如终端接收到两个基站发送的DCI指示该终端向两个基站发送物理上行控制信道(Physical Uplink Controling Channel，PUCCH)，根据默认的TCI向两个基站发送上行信道，导致终端向同一个基站发送上行信道，如果该基站和终端的链路条件比较差，会导致传输失败，也没有得到两个TRP联合传输的增益。

具体实施方式
为使本申请的目的、技术方案和优点更加清楚，下面将结合本申请中的附图，对本申 请中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
本发明的说明书和权利要求书及上述附图中的术语“第一”、“第二”、“第三”“第四”等(如果存在)是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便这里描述的本发明的实施例例如能够以除了在这里图示或描述的那些以外的顺序实施。此外，术语“包括”和“具有”以及他们的任何变形，意图在于覆盖不排他的包含，例如，包含了一系列步骤或单元的过程、方法、***、产品或设备不必限于清楚地列出的那些步骤或单元，而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。
图1为本申请提供的信息传输方法的应用场景示意图。如图1所示，多发送和接收点(multiple Transmission and Reception Point，multi-TRP)通信场景中包括：第一基站101、第二基站102和终端103。
其中，终端103(例如移动电话)可以通过无线网络分别与第一基站101和第二基站102进行交互，第一基站101可以通过无线网络与第二基站102。可选地，无线网络可以为2G网络、3G网络、4G网络或者5G网络等。
具体的，第一基站101和/或第二基站102可以向终端103发送DCI，DCI用于指示终端103向基站发送上行信道。
例如，第一基站101和第二基站102交互及时，第一基站101和第二基站102中的任意一个向终端103发送DCI(该DCI中包括第一基站101和第二基站102各自下发的控制信息)。
例如，第一基站101和第二基站102交互不及时，第一基站101向终端103发送DCI(该DCI中包括第一基站101下发的控制信息)，第二基站102向终端103发送DCI(该DCI中包括第二基站102下发的控制信息)。
需要说明的是，图1中示例性的给出了2个基站，本申请实施例对基站的具体数量不做特别限制。
在实际应用中，第一基站101和第二基站102中的任意一个基站向终端103发送DCI时，终端103可以根据预先接收的第一高层配置信息确定一个TCI，并根据该TCI向发送DCI的基站发送上行信道。第一基站101和第二基站102分别向终端103发送DCI时，终端103可以根据预先接收的第二高层配置信息确定两个TCI，并根据其中一个TCI向第一基站101发送上行信道，根据其中另一个TCI向第二基站102发送上行信道。从而避免现有技术中，终端无法确定根据两个TCI中的那个TCI向该基站发送上行信道、或者无法确定根据该TCI向那个基站发送上行信道的问题，提高通信可靠性。
下面以具体地实施例对本发明的技术方案进行详细说明。下面这几个具体的实施例可以相互结合，对于相同或相似的概念或过程可能在某些实施例不再赘述。

下面，对现有技术中存在的技术问题一进行说明。
现有技术中存在的技术问题一：在如图1所示的multi-TRP通信场景中，终端分别向第一基站和第二基站重复发送各自对应的PUCCH，例如，终端向第一基站重复发送PUCCH-1，终端向第二基站重复发送PUCCH-2。在终端向第一基站重复发送PUCCH-1、向第二基站重复发送PUCCH-2的过程中，终端接收到第一基站发送的第一DCI 0_0，第一DCI 0_0用于指示终端向第一基站发送PUSCH。在现有的通信协议中，将专用PUCCH资源中的最低专用PUCCH标识对应PUCCH资源的TCI确定为PUSCH的TCI。由于最低专用PUCCH标识对应PUCCH资源的TCI可以有两个，因此根据在现有的通信协议，可以确定出PUSCH的两个TCI，从而导致终端无法确定根据两个TCI中的那个一TCI向该基站发送PUSCH，进而导致通信失败。
针对上述技术问题一，本申请提出一种信息传输方法，用于解决该技术问题一，具体的，请参见图3实施例。
图3为本申请提供的信息传输方法的流程示意图二。如图3所示，本实施例提供的信息传输方法包括：
S301：第一基站向终端发送第一高层配置信息，第一高层配置信息中包括至少一个专用PUCCH标识、每个专用PUCCH标识对应PUCCH资源的TCI，TCI中包括TCI标识。
例如，第一高层配置信息中的专用PUCCH标识、专用PUCCH标识对应PUCCH资源的TCI具有如下表1所示的对应关系。
表1
专用PUCCH标识 传输指示信息
2 TCI 3；TCI 2
3 TCI 4
4 TCI 3；TCI 5
6 TCI 2
7 TCI 1；TCI 4
在表1中，专用PUCCH标识一列中的2、3、4、6、7均为专用PUCCH标识。
在表1中，传输指示信息中的TCI 3、TCI 2、TCI 4、TCI 5、TCI 1均为TCI，其中，1、2、3、4、5为TCI标识。
例如，专用PUCCH标识2对应的TCI为TCI 3和TCI 2。
例如，专用PUCCH标识3对应的TCI为TCI 4。
S302：第一基站向终端发送第一下行控制信息DCI，第一DCI用于指示终端发送物理上行共享信道PUSCH。
S303：终端根据专用PUCCH标识对应PUCCH资源的TCI的个数，确定中间专用PUCCH标识，中间专用PUCCH标识对应PUCCH资源的TCI的个数为第一预设值。
其中，每个专用PUCCH标识对应至少一个TCI。其中，第一预设值可以为1，也可以为2。
例如在表1中，由于专用PUCCH标识3对应的TCI的个数为1(即TCI 4)、专用PUCCH标识6对应的TCI的个数为1(即TCI 2)。因此，第一预设值为1时，中间专用PUCCH 标识分别为3、6。
例如在表1中，由于专用PUCCH标识为2对应的TCI的个数为2(即TCI 3和TCI 2)、专用PUCCH标识为4对应的TCI的个数为2(即TCI 3和TCI 5)、专用PUCCH标识为7对应的TCI的个数为2(即TCI 1和TCI 4)。因此，第一预设值为2时，中间专用PUCCH标识分别为2、4、7。
S304：终端根据中间专用PUCCH标识，确定PUSCH的第一TCI。
在一种可能的实施方式中，第一预设值等于1；可以在中间专用PUCCH标识中确定目标专用PUCCH标识；将目标专用PUCCH标识对应PUCCH资源的TCI确定为上行信道(PUSCH)的第一TCI，其中，目标专用PUCCH标识为中间专用PUCCH标识中的最小标识。
例如在表1中，第一预设值等于1时，在中间专用PUCCH标识中确定的目标专用PUCCH标识为3，目标专用PUCCH标识3对应的TCI为TCI 4，因此将TCI 4确定为第一TCI。
在另一种可能的实施方式中，第一预设值等于1；可以在中间专用PUCCH标识对应PUCCH资源的TCI中确定目标TCI；将目标TCI确定为上行信道(PUSCH)的第一TCI；其中，目标TCI的TCI标识为中间专用PUCCH标识对应PUCCH资源的TCI标识中的最小标识、或最大标识。
例如在表1中，第一预设值等于1时，中间专用PUCCH标识3对应的TCI为TCI 4，中间专用PUCCH标识6对应的TCI为TCI 2。当目标TCI的TCI标识为中间专用PUCCH标识对应PUCCH资源的TCI标识中的最小标识时，将TCI 2确定为目标TCI；当目标TCI的TCI标识为中间专用PUCCH标识对应PUCCH资源的TCI标识中的最大标识时，将TCI4确定为目标TCI。
在另一种可能的实施方式中，第一预设值等于2；可以在中间专用PUCCH标识中确定目标专用PUCCH标识；根据目标专用PUCCH标识，确定目标TCI；将目标TCI确定为上行信道(PUSCH)的第一TCI；其中，目标专用PUCCH标识为中间专用PUCCH标识中的最小标识。
例如在表1中，第一预设值等于2时，中间专用PUCCH标识分别为2、4、7。在中间专用PUCCH标识中确定的目标专用PUCCH标识为2。
可选地，可以根据目标专用PUCCH标识对应PUCCH资源的TCI的位置，确定目标TCI；其中，目标TCI为目标专用PUCCH标识对应PUCCH资源的TCI的位置中的第一位置对应的TCI、或者第二位置对应的TCI。
需要说明的是，TCI的位置为TCI在预设排列顺序中的位置。
例如在表1中，目标专用PUCCH标识2对应的TCI的预设排列顺序为TCI 3、TCI 2。其中，第一位置为预设排列顺序中的第一个TCI所在的位置，第二位置为预设排列顺序中的第二个TCI所在的位置。
例如，目标TCI为第一位置对应的TCI时，目标TCI为TCI 3；目标TCI为第二位置对应的TCI时，目标TCI为TCI 2。
可选地，可以根据目标专用PUCCH标识对应PUCCH资源的TCI标识，确定目标TCI；其中，目标TCI的TCI标识为目标专用PUCCH标识对应PUCCH资源的TCI标识中的最 小标识、或最大标识。
例如在表1中，目标专用PUCCH标识为2时，对应的TCI分别为TCI 3、TCI 2，因此目标TCI的TCI标识为目标专用PUCCH标识对应PUCCH资源的TCI标识中的最小标识时，目标TCI为TCI 2；目标TCI的TCI标识为目标专用PUCCH标识对应PUCCH资源的TCI标识中的最大标识时，目标TCI为TCI 3。
在另一种可能的实施例中，还可以根据每个专用PUCCH标识对应PUCCH资源的TCI标识，确定目标TCI；将目标TCI确定为上行信道的第一TCI；其中，目标TCI的TCI标识为专用PUCCH标识对应PUCCH资源的TCI标识中的最小标识、或最大标识。
例如，目标TCI的TCI标识为专用PUCCH标识对应PUCCH资源的TCI标识中的最小标识时，目标TCI为TCI 1；目标TCI的TCI标识为专用PUCCH标识对应PUCCH资源的TCI标识中的最大标识时，目标TCI为TCI 5。
S305：第一基站根据专用PUCCH标识对应PUCCH资源的TCI的个数，确定中间专用PUCCH标识，中间专用PUCCH标识对应PUCCH资源的TCI的个数为第一预设值。
具体的，第一基站执行S304的过程与终端执行S303的过程相同，此处不再赘述第一基站执行S305的过程。
S306：第一基站根据中间专用PUCCH标识，确定PUSCH的第一TCI。
具体的，第一基站执行S306的过程与终端执行S304的过程相同，此处不再赘述第一基站执行S306的过程。
需要说明的是，S303-S304的执行顺序与S305-S306的执行顺序可以调整，即可以在执行完S305-S306之后，执行S303-S304。
S307：终端根据第一TCI向第一基站发送PUSCH。
S308：第一基站根据第一TCI接收来自终端的PUSCH。
本实施例提供的信息传输方法包括：第一基站向终端发送第一高层配置信息，第一高层配置信息中包括至少一个专用PUCCH标识、每个专用PUCCH标识对应PUCCH资源的TCI，TCI中包括TCI标识；终端接收来自第一基站的第一下行控制信息DCI，第一DCI用于指示终端向其中一个基站发送物理上行共享信道PUSCH；终端根据每个专用PUCCH标识对应PUCCH资源的TCI的个数，确定中间专用PUCCH标识，中间专用PUCCH标识对应PUCCH资源的TCI的个数为第一预设值；终端根据中间专用PUCCH标识，确定PUSCH的第一TCI；第一基站根据专用PUCCH标识对应PUCCH资源的TCI的个数，确定中间专用PUCCH标识，中间专用PUCCH标识对应PUCCH资源的TCI的个数为第一预设值；第一基站根据中间专用PUCCH标识，确定PUSCH的第一TCI；终端根据第一TCI向第一基站发送PUSCH；第一基站根据第一TCI接收来自终端的PUSCH。在上述方法中，终端根据中间专用PUCCH标识可以确定出PUSCH唯一的一个第一TCI，保障终端和第一基站之前的正常通信。避免由于技术中终端无法确定根据两个TCI中的那个一TCI向该基站发送PUSCH，从而导致通信失败的问题。
下面，对现有技术中存在的技术问题二进行说明。
现有技术中存在的技术问题一：在如图1所示multi-TRP通信场景中，第一基站和第二基站分别向终端发送DCI，DCI用于指示终端向第一基站发送PUCCH。例如，第一基站向终端发送第一DCI(例如DCI 1_0)，第二基站向终端发送第二DCI(例如DCI 1_0)。 在实际应用中，终端接收到第一DCI之后需要根据一TCI向第一基站发送PUCCH(例如，PUCCH-1)，终端接收到第二DCI之后需要根据另一TCI向第二基站发送PUCCH(例如，PUCCH-2)。但是按照现有的通信协议，终端发送的两个PUCCH没有各自对应的TCI，此时采用默认TCI发送两个PUCCH，导致终端发送的PUCCH是面向同一个基站，如果该基站和终端之间的链路条件差，造成传输失败，无法得到两个TRP联合传输的增益。
针对上述技术问题二，本申请提出一种信息传输方法，用于解决技术问题二，具体的，请参见图4实施例。
图4为本申请提供的信息传输方法的流程示意图三。如图4所示，本实施例提供的信息传输方法包括：
S401：第一基站向终端发送第二高层配置信息，第二高层配置信息包括至少两个不同的控制资源集池标识、每个控制资源集池标识各自对应的至少一个控制资源集标识、每个控制资源集标识所在控制资源集的TCI，至少两个不同的控制资源集池标识包括第一控制资源集池标识和第二控制资源集池标识。
可选地，第二基站也可以向终端发送第二高层配置信息。
例如，第二高层配置信息中的至少两个不同的控制资源集池标识、每个控制资源集池标识各自对应的至少一个控制资源集标识、每个控制资源集标识所在控制资源集的TCI具有如下表2所示的对应关系。
表2

0 1 TCI 3
1 0 TCI 2
2 1 TCI 4
3 0 TCI 8
在表2中，第一控制资源集池标识为0，第二控制资源集池标识为1。在实际应用中，将未配置控制资源集池标识的位置，设置为0。
例如，第二高层配置信息中的至少两个不同的控制资源集池标识、每个控制资源集池标识各自对应的至少一个控制资源集标识、每个控制资源集标识所在控制资源集的TCI具有如下表3所示的对应关系。
表3
控制资源集标识 控制资源集池标识 传输指示信息
0 1 TCI 3
1 1 TCI 2
2 1 TCI 4
3 0 TCI 8
S402：第一基站向第二基站发送第二高层配置信息。
S403：第一基站向终端发送第一下行控制信息DCI，第一DCI用于指示终端向其中一个基站发送第一物理上行控制信道PUCCH。
可选地，第一DCI可以为DCI 1_0、DCI 1_1、DCI 1_2等。
S404：第二基站向终端发送第二DCI，第二DCI用于指示终端发送第二PUCCH。

在一种可能的实施方式中，可以根据第一控制资源集池标识，在第二高层配置信息中确定第一目标控制资源集标识；将第一目标控制资源集标识所在的控制资源集的TCI确定为第一PUCCH的第一TCI，其中，第一目标控制资源集标识为第一控制资源集池标识对应的至少一个控制资源集标识中最小标识、或最大标识。
例如在表2中，第一控制资源集池标识0对应的至少一个控制资源集标识分别为1、3。当前第一目标控制资源集标识为第一控制资源集池标识对应至少一个控制资源集标识中最小标识时，第一目标控制资源集标识为1，因此，将第一目标控制资源集标识所在的控制资源集的TCI(即TCI 2)确定为第一PUCCH的第一TCI。当前第一目标控制资源集标识为第一控制资源集池标识对应至少一个控制资源集标识中最大标识时，第一目标控制资源集标识为3，因此，将第一目标控制资源集标识所在的控制资源集的TCI(即TCI 8)确定为第一PUCCH的第一TCI。
例如在表3中，第一控制资源集池标识0仅仅对应一个控制资源集标识3，因此将控制资源集标识3确定为第一目标控制资源集标识，将第一目标控制资源集标识所在的控制资源集的TCI(即TCI 8)确定为第一PUCCH的第一TCI。
S406：终端根据第二控制资源集池标识，在第二高层配置信息中确定第二PUCCH的第二TCI。
在一种可能的实施方式中，可以根据第二控制资源集池标识，在第二高层配置信息中确定第二目标控制资源集标识，第二目标控制资源集标识为第二控制资源集池标识对应至少一个控制资源集标识中最小标识、或最大标识；将第二目标控制资源集标识所在的控制资源集的TCI确定为第二PUCCH的第二TCI。
例如在表2中，第二控制资源集池标识1对应的至少一个控制资源集标识分别为0、2。当前第二目标控制资源集标识为第二控制资源集池标识对应至少一个控制资源集标识中最小标识时，第二目标控制资源集标识为0，因此，将第二目标控制资源集标识所在的控制资源集的TCI(即TCI 3)确定为第二PUCCH的第二TCI。当前第二目标控制资源集标识为第二控制资源集池标识对应至少一个控制资源集标识中最大标识时，第二目标控制资源集标识为2，因此，将第二目标控制资源集标识所在的控制资源集的TCI(即TCI 4)确定为第二PUCCH的第二TCI。
例如在表3中，第二控制资源集池标识1对应的至少一个控制资源集标识分别为0、1、2，当前第二目标控制资源集标识为第二控制资源集池标识对应至少一个控制资源集标识中最小标识时，第二目标控制资源集标识为0，因此，将第二目标控制资源集标识所在的控制资源集的TCI(即TCI 3)确定为第二PUCCH的第二TCI。当前第二目标控制资源集标识为第二控制资源集池标识对应至少一个控制资源集标识中最大标识时，第二目标控制资源集标识为2，因此，将第二目标控制资源集标识所在的控制资源集的TCI(即TCI 4) 确定为第二PUCCH的第二TCI。
可选地，S405和S406的执行顺序可以该变，也可以同时执行S405和S406中的执行方法。
S407：第一基站根据第一控制资源集池标识，在第二高层配置信息中确定第一PUCCH的第一TCI。
需要说明的是，第一基站执行S407的过程与终端执行S405的过程相同，此处不再赘述S407的执行过程。
S408：第二基站根据第二控制资源集池标识，在第二高层配置信息中确定第二PUCCH的第二TCI。
