具体实施方式
为使本公开要解决的技术问题、技术方案和优点更加清楚，下面将结合附图及具体实施例进行详细描述。
参见图1，图1是本公开实施例可应用的网络结构示意图，如图1所示，包括终端11和网络侧设备12，终端11可以是用户终端(User Equipment，UE)或者其他终端设备，例如：手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)、个人数字助理(Personal Digital Assistant，PDA)、移动上网装置(Mobile Internet Device，MID)、可穿戴式设备(Wearable Device)、机器人、车辆等终端侧设备，需要说明的是，在本公开实施例中并不限定终端的具体类型。网络侧设备12可以是发送接收点(transmission reception point，TRP)，且本公开实施例中可以应用于多TRP场景。进一步的，网络侧设备12可以接入网设备，如基站，例如：宏站、LTE eNB、5G NR NB等；网络侧设备也可以是小站，如低功率节点(Low Power Node，LPN)、pico、femto等小站，或者网络侧设备可以接入点(Access Point，AP)；网络侧设备也可以是中央单元(Central Unit，CU)。需要说明的是，在本公开实施例中并不限定网络侧设备的具体类型。
请参见图2，图2是本公开实施例提供的一种传输信息确定方法的流程图，该方法应用于终端，如图2所示，包括以下步骤：
步骤201、获取控制信道的重复传输信息；
步骤202、依据所述控制信道的重复传输信息，确定所述控制信道对应的第一信号的重复传输信息；
步骤203、基于所述第一信号的重复传输信息，执行所述第一信号的重复检测或者执行所述第一信号的重复发送。
其中，上述获取控制信道的重复传输信息可以是接收网络侧设备发送的控制信道的重复传输信息，该发送可以是网络侧设备动态发送的，或者可以是网络侧设备预先配置的。例如：控制信道的重复传输信息可以是网络侧动态发送的2个重复的控制信息，又例如，控制信道的重复传输信息可以是网络侧设备通过高层信令配置的，如通过高层信令预先为上述终端配置的。
进一步的，控制信道的重复传输信息可以是协议约定的，从而步骤201可以是从终端的本地调用控制信道的重复传输信息。
上述控制信道可以是下行控制信道，例如：物理下行控制信道(Physical downlink control channel，PDCCH)。另外，本公开实施例中，控制信道也可以理解为控制信号或者控制信息。
上述控制信道的重复传输信息可以是控制信道的重复传输方案信息或者重复传输参数等等。
上述第一信号可以是上述控制信道调用的上行或者下行信号。例如：所述第一信号包括如下至少一项：PDSCH、PUSCH、非周期CSI-RS和传输块。
上述第一信号的第一信号的重复传输信息可以是，第一信号的重复传输方案信息或者重复传输参数等等。
上述依据所述控制信道的重复传输信息，确定所述控制信道对应的第一信号的第一信号的重复传输信息可以是，依据上述控制信道的重复传输信息与第一信号的重复传输信息之间的对应关系，确定上述第一信号的重复传输信息；或者上述依据所述控制信道的重复传输信息，确定所述控制信道对应的第一信号的第一信号的重复传输信息可以是，将所述控制信道的重复传输信息所指示的重复传输信息作为上述第一信号的重复传输信息。
上述基于所述第一信号的重复传输信息，执行所述第一信号的重复检测可以是，基于所述第一信号的重复传输信息，多次检测所述第一信号，即网 络侧设备采用重复传输方式发送第一信号，从而终端侧多次检测第一信号，例如：在不同的资源上检测第一信号；上述基于所述第一信号的重复传输信息，执行所述第一信号的重复发送可以是，终端采用重复传输方式发送第一信号，例如：在不同的资源上发送第一信号。
需要说明的是，本公开实施例中，第一信号在重复传输时，每次传输时第一信号的全部内容信号并不限定相同，例如：不同次传输的第一信号的冗余版本号不同，当然，也可以全部内容相同。
本公开实施例中，通过上述步骤可以实现第一信号进行传输重复，从而提高信号的传输可靠性。例如：第一信号的重复传输次数与上述控制信道的重复传输次数相同，即针对上述控制信道的每次传输，网络侧设备或者终端均发送一次第一信号。例如：网络侧设备在采用PDCCH重复传输时，每个PDCCH均调度一个PDSCH，即实现PDSCH的重复传输，这样，终端无论根据哪个PDCCH都可以正确的确定PDSCH的传输参数，避免网络侧设备和终端因为对控制信道接收位置理解不同而造成的PDSCH传输失败，同时还可以提高PDSCH的传输可靠性。当然，对此不作限定，例如：可以是控制信道传输3次，而第一信号传输2次，或者第一信号的重复传输次数大于控制信道的重复传输次数等，这样同样可以提高信号的传输可靠性。
作为一种可选的实施方式，所述控制信道的重复传输信息包括以下至少一项：

可选地，上述至少两个控制信息指示的传输参数相同，或者，所述至少两个控制信息指示的传输参数不同。
其中，控制信息指示的传输参数可以是根据控制信息的信令内容确定的 传输参数，例如：如图3所示，PDCCH1和PDCCH2分别在时隙(Slot)n和Slot n+1传输，且PDCCH1和PDCCH2携带的信令内容中的K0＝1，从而可以确定一个PDSCH在slot n+1传输，另一个PDSCH在slot n+2传输，这两个PDSCH为上述第一信号的重复传输，也就是说，上述至少两个控制信息可以指示相同的时域资源传输参数，当然，对此不作限定，例如：也可以指示不同的传输参数等。

可选地，上述控制信道的重复传输方案信息、所述控制信道的重复传输参数、所述控制信道与所述第一信号的联合传输方案信息、所述控制信道与所述第一信号的联合传输参数中的至少一项由网络侧配置。
例如：网络侧设备通过高层信令或者RRC信令配置上述信息。
作为一种可选的实施方式，所述第一信号的重复传输信息包括如下至少一项：
所述第一信号的重复传输方案信息；
所述第一信号的重复传输参数。
其中，上述第一信号的重复传输参数可以包括如下至少一项：

该实施方式中，由于可以确定第一信号的重复传输方案信息和所述第一信号的重复传输参数，这样终端可以准确地检测或者发送第一信号，以提高信号的传输可靠性。
作为一种可选的实施方式，所述依据所述控制信道的重复传输信息，确定所述控制信道对应的第一信号的重复传输信息，包括：

Figure PCTCN2021098301-appb-000001
在表1中，当控制信道的重复传输方案被配置为时隙间时分复用重复传输，终端就可以确定对应的第一信号的重复传输方案也为时隙间时分复用重复传输。以上仅针对控制信道和第一信号重复传输方案的关联做一个示意性的说明，还可以包含其它的对应关系，本公开实施例不做限制。此外，控制信道和PDSCH的重复传输方案也不限制为表1中的几种情况。
进一步的，控制信道重复传输方案和第一信号重复传输方案之间的映射关系可以在协议中预先规定好，这样，当终端接收到控制信道重复传输方案配置以后，就可以隐式地确定第一信号的重复传输方案。
表2：
控制信道重复传输次数 第一信号重复传输次数
2 2
3 3
4 4
8 16
通过表2可以定义第一信号重复传输次数和控制信道重复传输次数之间的映射关系，其中，该映射关系可以在协议中预先规定，当然，也可以是网络侧配置给终端。

上述依据所述控制信道的重复传输方案信息，确定所述第一信号的重复传输方案信息和重复传输参数中的至少一项可以是，上述依据所述控制信道的重复传输方案信息，确定所述第一信号的重复传输方案信息和重复传输参数，其中，具体的确定方式可以参见上述描述，此处不作赘述。

其中，这里的重复传输方案信息可以表示控制信道进行重复传输，从而所述第一信号的TCI状态为所述控制信道所在的至少两个控制资源集合的TCI状态的组合。以控制信道为PDCCH为例，PDCCH1和PDCCH2所在CORESET的TCI状态分别为TCI状态1和TCI状态2，则上述第一信号的TCI状态为TCI状态1和TCI状态2。
该实施方式中，可以实现根据控制信道的重复传输方案信息隐式地确定第一信号的TCI状态，且该实施方式中，控制信道还不需要携带第一信号的TCI状态信息，从而节约控制信道的开销。

需要说明的是，本实施例作为与图2所示的实施例中对应的网络侧设备的实施方式，其具体的实施方式可以参见图2所示的实施例的相关说明，为了避免重复说明，本实施例不再赘述，且还可以达到相同有益效果。
下面以三个实施例对本公开实施例提供的方法进行举例说明：
实施例1：
该实施例中，以终端接收网络侧设备发送的控制信道的控制信道的重复传输信息，终端根据控制信道的重复传输信息确定第一信号的重复传输方案信息或重复传输参数进行举例说明，具体可以包括以下：
针对控制信道的重复传输信息为两个或以上具有相同信令内容的控制信息的情况：
当PDCCH采用重复传输方案时，例如图3所示时隙间重复方案，终端根据两个或两个以上具有相同信令内容的控制信息确定PDSCH的重复传输参数，即终端根据PDCCH1和PDCCH2分别去确定PDSCH的重复传输参数(即2组传输参数)。根据PDCCH1以及控制信息的内容(K0＝1)可以确定 PDSCH在slot n+1传输，根据PDCCH2以及控制信息的内容(K0＝1)可以确定PDSCH在slot n+2传输。相应地，网络侧设备也会配合着在slot n+1和slot n+2分别发送PDSCH。这样，终端无论按照哪个PDCCH的位置以及控制信息的内容去确定PDSCH的位置都会在相应的时隙上检测到PDSCH。且PDSCH也采用重复传输的方式，大大地增加的PDSCH的传输可靠性。
需要说明的是，本公开实施例中，可以通过在协议中规定终端侧的行为实现的，即终端根据接收或检测的2个或以上PDCCH分别确定2组PDSCH的传输参数。
需要说明的是，该实施例中，仅是以第一信号为PDSCH进行举例说明，该实施例中第一信号还可以扩展到PUSCH，传输块以及其它PDCCH调度或指示的物理信道或物理信号，例如非周期CSI-RS。此外跨时隙调度PDSCH的情况还可以扩展到时隙内调度PDSCH或PUSCH，以及确定PDSCH，PUSCH或非周期CSI-RS的TCI状态的情况中，均是根据至少两个PDCCH的传输位置和控制信息中指示的参数确定至少两组传输参数，此处不作赘述。
实施例2：
该实施例中，以控制信道的重复传输信息为高层信令配置的控制信道的重复传输方案信息或重复传输参数的情况，或者高层信令配置的控制信道与第一信号的联合重复传输方案信息或联合重复传输参数的情况进行举例说明。
另外，该实施例中，还可以在以上方案的基础上还可以做一些扩展，即当网络侧设备配置控制信道进行重复传输时，终端确定第一信号也进行相应的重复传输。即通过网络侧设备配置的控制信道的重复传输方案信息或重复传输参数隐式地确定第一信号的重复传输方案信息或重复传输参数。
例如，网络侧设备配置一个高层参数(例如RepSchemeEnabler_PDCCH)用于配置控制信道的重复传输方案，重复传输方案可以包括2个或以上控制信息采用如下复用方式进行重复传输：时分复用；频分复用；时隙内时分复用；时隙间时分复用；控制资源集合(CORESET)内复用；控制资源集合(CORESET)间复用等。其中2个或以上控制信息用于调度同一个第一信号。
终端可以根据配置的控制信道的重复传输信息，确定第一信号也同样采用了重复传方案，且第一信号的重复传输方案可以根据控制信道的重复传输 方案隐式地获得。例如，预定义一种第一信号的重复方案和控制信道的重复方案的关联关系。具体地，关联关系可以如上述表1所示。
在表1中，当控制信道的重复方案被配置为时隙间时分复用重复传输，终端就可以确定对应的第一信号的重复方案也为时隙间时分复用重复传输。以上仅针对控制信道和第一信号重复传输方案的关联做一个示意性的说明，还可以包含其它的对应关系，本公开不做限制，此外，控制信道和第一信号的重复方案也不限制为表1中的几种情况。控制信道的重复传输方案和第一信号重复传输方案之间的映射关系可以在协议中预先规定好，这样，当终端接收到控制信道的重复传输方案配置以后，就可以隐式地确定第一信号的重复传输方案了。
此外，还可以定义P第一信号的重复传输次数和控制信道的重复传输次数之间的映射关系，例如：上述表2所示，这样就可以根据网络侧设备配置的控制信道的重复传输方案和重复传输参数隐式地确定第一信号的重复传输参数。
又例如，还可以将表1和表2进行联合映射，预定义控制信道的重复传输方案或重复传输次数，与第一信号的重复传输方案或重复传输次数之间的映射关系。
又例如，网络侧设备可以对控制信道和第一信号的重复传输方案进行联合配置，即配置一个高层参数(如RepSchemeEnabler_r17)同时指示控制信道和第一信号的重复方案，例如配置的高层参数指示时隙内重复，表示控制信道和第一信号均采用时隙内重复的方式进行传输；配置的高层参数指示时隙间重复，表示控制信道和第一信号均采用时隙间重复的方式进行传输。控制信道和第一信号重复传输的组合也可以如表1所示。
实施例:3：
该实施例中，以终端根据高层信令配置的控制信道的重复传输方案隐式地确定第一信号的TCI状态为2个或以上控制信道传输所在控制资源集合的TCI状态的组合。
当2个或以上控制信息调度同一个第一信号时，如图5所示。若控制信息中不包含TCI域(例如没有配置tci-PresentInDCI，或者没有配置 tci-PresentInDCI-ForFormat1_2，或者DCI format为1_0)，第一信号的TCI状态和调度它的控制信道传输所在的CORESET的TCI状态相同。当控制信道采用重复传输时，例如图5中的PDCCH1和PDCCH2，哪个PDCCH是调度的PDCCH对终端来说是不明确的。如果网络侧设备将PDCCH1定义为调度的PDCCH，就将按照PDCCH1传输所在CORESET的TCI状态来发送第一信号，而如果终端侧将PDCCH2定义为调度的PDCCH，就会按照PDCCH2传输所在的CORESET的TCI状态假设来接收第一信号，因此会造成终端和网络设备侧对PDSCH的TCI状态理解不一致，进而导致传输失败。
按照本公开实施的方法，当终端收到网络侧配置控制信道进行重复传输时，就会隐式地确定第一信号的TCI状态为PDCCH1和PDCCH2所在CORESET的TCI状态的组合，例如，确定第一信号为空分复用传输(例如表1中的最后一个方案)，并且网络侧设备会配合着使用PDCCH1和PDCCH2所在CORESET的TCI状态的组合来接收PDSCH。又例如，当PDCCH1和PDCCH2所在时域资源不同时，还可以确定第一信号的重复传输方案为时分复用(例如表1中的第一个或第二个方案)，即PDCCH1和PDCCH2分别调度PDSCH1和PDSCH2，且PDSCH1和PDSCH2的时域资源也是不同的，此时，PDSCH1和PDSCH2的TCI状态分别为PDCCH1和PDCCH2所在CORESET的TCI状态。又例如，当PDCCH1和PDCCH2所在时域资源不同时，还可以确定第一信号的重复传输方案为空分复用+时分复用，即PDCCH1和PDCCH2分别调度PDSCH1和PDSCH2，且PDSCH1和PDSCH2的时域资源也是不同的，此时PDSCH1和PDSCH2的TCI状态均为PDCCH1和PDCCH2所在CORESET的TCI状态的组合。具体使用哪一种重复传输方案可以取决于协议中预定义的或网络设备预配置的PDCCH的重复传输方案与第一信号的重复传输方案之间的映射关系。
使用本公开实施例的方法，当控制信道在采用重复传输时，其调度或指示的物理信道或物理信号也采用重复的方式进行传输。既可以避免网络侧设备和终端因为对控制信息接收位置理解不同而造成的物理信道或物理信号传输失败，同时还可以提高物理信号或物理信道的传输可靠性。
