具体实施方式
为了能够更加详尽地了解本发明实施例的特点和技术内容，下面结合附图对本发明实施例的实现进行详细阐述，所附附图仅供参考说明之用，并非用来限定本发明实施例。
在对本发明实施例提供的信息传输方法进行详细说明之前，先对上行传输机会进行简要说明。
非授权频谱是国家和地区划分的可用于无线电设备通信的频谱，该频谱通常被认为是共享频谱，即不同通信系统中的通信设备只要满足国家或地区在该频谱上设置的法规要求，就可以使用该频谱，不需要向政府申请专有的频谱授权。
为了让使用非授权频谱进行无线通信的各个通信系统在该频谱上能够友好共存，一些国家或地区规定了使用非授权频谱必须满足的法规要求。例如，电子设备(或者说，通信设备)遵循先听后说(Listen Before Talk，LBT)原则，即电子设备在非授权频谱的信道上进行信号发送前，需要先进行信道侦听，或者说，进行空闲信道检测(Clear Channel Assessment，CCA)，只有当信道侦听结果为信道空闲时，电子设备才能进行信号发送；如果电子设备在非授权频谱的信道上的信道侦听结果为信道忙，则电子设备不能进行信号发送。为了保证公平性，在一次传输中，电子设备使用非授权频谱的信道进行信号传输的时长不能超过最大信道占用时间(Maximum Channel Occupancy Time，MCOT)。
在非授权频谱上的信号传输包括以下基本概念：
MCOT，指LBT成功后允许使用非授权频谱的信道进行信号传输的最大时间长度，不同信道接入优先级下有不同的MCOT。当前MCOT的最大取值为10ms。应理解，该MCOT为信号传输占用的时间。
信道占用时间(Channel Occupancy Time，COT)：指LBT成功后使用非授权频谱的信道进行信号传输的时间长度，该时间长度内信号占用信道可以是不连续的。其中，一次COT最长不能超过20ms，并且，该COT内的信号传输占用的时间长度不超过MCOT。
网络设备(即基站)的信道占用时间(gNB-initiated COT)，也称为网络设备发起 的COT，指网络设备LBT成功后获得的一次信道占用时间。网络设备的信道占用时间内除了可以用于下行传输，也可以在满足一定条件下用于UE进行上行传输。
终端设备的信道占用时间(UE-initiated COT)：也称为UE发起的COT，指UE LBT成功后获得的一次信道占用时间。
下行传输机会(DownLink，DL burst)，网络设备进行的一组下行传输(即包括一个或多个下行传输)，该组下行传输为连续传输(即多个下行传输之间没有空隙)，或该组下行传输中有空隙但空隙小于或等于16μs。如果网络设备进行的两个下行传输之间的空隙大于16μs，那么认为该两个下行传输属于两次下行传输机会。
上行传输机会(UpLink，UL burst)：一个UE进行的一组上行传输(即包括一个或多个上行传输)，该组上行传输为连续传输(即多个上行传输之间没有空隙)，或该组上行传输中有空隙但空隙小于或等于16μs。如果该UE进行的两个上行传输之间的空隙大于16μs，那么认为该两个上行传输属于两次上行传输机会。
网络设备的信道占用时间的示意图如图1所示，当网络设备获得COT后，可以将该COT内的资源用于UE进行上行传输。在网络设备的COT内发生的上行传输机会，如果该上行传输机会的起始位置和下行传输机会的结束位置之间的空隙小于16μs，UE可以立即进行该上行传输(也称为Cat-1 LBT)；如果在该网络设备的COT内，该上行传输机会后面没有下行传输机会，UE在传输前可以进行Cat-2 LBT；如果在该网络设备的COT内，任意两次相邻的传输之间的空隙小于或等于25μs，UE可以进行Cat-2 LBT。
其中，Cat-1 LBT可以指网络设备在空隙结束后不做信道检测而进行传输；Cat-2 LBT可以指网络设备做单时隙信道检测；具体地，Cat-2 LBT可以包括25μs的单时隙信道检测和16μs的单时隙信道检测。在网络设备的COT内发生的上行传输机会，如果该上行传输机会的起始位置和最近一次下行传输机会的结束位置之间的空隙为16μs，UE可以在该上行传输机会前进行16μs的Cat-2 LBT；如果该上行传输机会的起始位置和最近一次下行传输机会的结束位置之间的空隙为25μs，UE可以在该上行传输机会前进行25μs的Cat-2 LBT。网络设备可以保证该上行传输机会的起始位置和最近一次下行传输机会的结束位置之间的空隙的大小，并将该空隙大小信息或对应的LBT方式通知给终端设备。
应理解，网络设备获得上述信道占用时间的方式可以是基于负载的设备(Load based equipment，LBE)的信道接入方式，即网络设备可以在业务到达后进行非授权频谱上的LBT，并在LBT成功后开始信号的发送；也可以是基于帧结构的设备(Frame based equipment，FBE)的信道接入方式，即网络设备周期性地进行非授权频谱上的LBT。
如果是基于LBE的信道接入方式，网络设备可以通过Cat-4 LBT来获得信道占用时间。Cat-4 LBT可以指通信设备的信道检测方式为基于竞争窗口大小调整的随机回退的多时隙信道检测。具体地，Cat-4 LBT根据传输业务的优先级可以包括不同的信道接入优先级。
如果是基于FBE的信道接入方式，信道占用时间的示意图如图2所示，在该方式中，帧结构是周期出现的，在一个帧结构内包括固定帧周期(长度不超过200ms)、信道占用时间(长度不超过固定帧周期的95％)、空闲时间(长度至少为信道占用时间的5％，最小值为100us，且位于固定帧周期的尾部)。网络设备在空隙时间内对非授权频谱做LBT(或者说对非授权频谱进行CCA检测，例如可以是单时隙信道检测或多时隙信道检测)；如果LBT成功，下一个固定帧周期内的信道占用时间可以用于传输信号；如果LBT失败，下一个固定帧周期内的信道占用时间不能用于传输信号。或者说，电子设备可以用于业务发送的信道资源是周期性出现的。
下面再针对信道接入类型的指示进行简要说明。
当终端设备被调度进行物理上行共享信道(Physical Uplink Shared CHannel，PUSCH)传输时，网络设备会通过携带上行授权(UL grant)的下行控制信息(Downlink Control Information，DCI)来指示该PUSCH对应的信道接入类型和信道接入优先级。
具体地，信道接入类型为1比特，用于指示Type 1信道接入类型或Type 2信道接入类型。其中，Type 1信道接入类型可以包括Cat-4 LBT，Type 2信道接入类型可以包括25μs的Cat-2 LBT。网络设备指示信道接入类型的原则是，如果待传输PUSCH属于网络设备的COT内，指示Cat-2 LBT，否则，指示Cat-4 LBT。
信道接入优先级(Channel Access Priority Class，CAPC)为2比特，当信道接入类型为Type 1信道接入类型时，该2比特用于从下表1中确定对应的信道接入参数。其中表1为Cat-4 LBT下不同信道接入优先级对应的信道接入参数的一个示意，p取值越小，信道接入优先级越高。
Figure PCTCN2019098755-appb-000001
表1
其中，m p是指信道接入优先级p对应的回退时隙个数，CW p是指信道接入优先级p对应的竞争窗口大小，CW min,p是指信道接入优先级p对应的CW p取值的最小值，CW max,p是指信道接入优先级p对应的CW p取值的最大值，T mcot,p是指信道接入优先级p对应的信道最大占用时间长度。
需要说明的是，在网络设备的信道占用时间内，可以只允许有一个下行传输与上行传输的转换点；其中，下行传输与上行传输的转换点是指在网络设备的信道占用时间内，由下行传输切换为上行传输的时刻。在网络设备的信道占用时间内，如图3所示，在终端设备待传输的第一PUSCH对应的信道接入类型被指示为Type 1信道接入类型例如Cat-4 LBT的情况下，所述第一PUSCH由网络设备的第一信道占用时间内的第一PDCCH调度，如果该终端设备接收网络设备发送的公共控制信息，根据该公共控制信息确定网络设备的第二信道占用时间共享给上行传输的资源，并确定该待传输的第一PUSCH属于该网络设备共享的信道占用时间内，那么该终端设备可以将第一PUSCH对应的Cat-4 LBT切换为Cat-2 LBT。
随着通信系统的演进，需要指示的信道接入类型可能包括Cat-1 LBT，Cat-2 LBT，Cat-4 LBT，其中，Cat-2 LBT包括25μs的Cat-2 LBT和16μs的Cat-2 LBT。另外，网络设备的信道占用时间内可能出现多于一个的下行传输与上行传输的转换点。在终端设备待传输的第一PUSCH对应的信道接入类型被指示为Type 1信道接入类型例如Cat-4 LBT的情况下，其中所述第一PUSCH由网络设备的第一信道占用时间内的第一PDCCH调度或所述第一PUSCH是预配置授权(Configured Grant)下的PUSCH，如果该终端设备接收网络设备发送的公共控制信息，根据该公共控制信息确定网络设备的第二信道占用时间包括共享给上行传输的资源，并确定该待传输的第一PUSCH属于该网络设备共享的信道占用时间内，那么该终端设备可以将第一PUSCH对应的Cat-4 LBT切换为其他信道接入类型。
需要说明的是，这里的切换可以指终端设备确定的信道接入方式发生变化，并不代 表终端设备需要执行切换这个动作。
在该场景下，如图4所示，终端设备确定上行传输机会属于网络设备的信道占用时间时，终端设备可以确定信道接入方式可以由Cat-4 LBT切换为25μs的Cat-2 LBT、16μs的Cat-2 LBT或Cat-1 LBT中的一种，或由低优先级的Cat-4 LBT切换为更高优先级的Cat-4 LBT例如由p＝2切换为p＝1。
终端设备还需要进一步确定应该使用25μs的Cat-2 LBT、16μs的Cat-2 LBT或Cat-1 LBT中的哪种LBT类型，和/或该LBT类型对应网络设备的信道占用时间内的哪一个空隙。

本发明实施例提供的信息传输方法的一种可选处理流程，如图6所示，包括以下内容中的至少部分：
步骤S201，终端设备接收网络设备发送的第一指示信息。
在一些实施例中，所述第一指示信息用于确定所述网络设备的信道占用时间内的至少一个信道接入方式，例如所述第一指示信息指示所述网络设备的信道占用时间内的至少一个信道接入方式。具体地，所述第一指示信息可以显性的直接指示所述网络设备的信道占用时间内的至少一个信道接入方式，例如，可通过所述第一指示信息对应的集合指示所述网络设备的信道占用时间内的至少一个信道接入方式；举例来说，所述第一指示信息为{00,01,10}，其中，“00”表示Cat-1，“01”表示16μs的Cat-2，“10”表示25μs的Cat-2。所述第一指示信息也可以隐性的指示所述网络设备的信道占用时间内的至少一个信道接入方式；举例来说，所述第一指示信息指示空隙的大小，根据空隙的大小判断检测信道时应该使用的信道接入方式。
可选地，所述第一指示信息可以是物理层信令，例如所述第一指示信息是DCI中包括的信息，其中所述DCI可以是公共控制信息或UE专用DCI。
可选地，所述第一指示信息可以是高层信令，例如所述第一指示信息是媒体接入控制(Media Access Control，MAC)控制单元(Control Element，CE)信令。
在另一些实施例中，所述第一指示信息除了用于确定所述网络设备的信道占用时间内的至少一个信道接入方式，还用于确定所述信道占用时间外的至少一个信道接入方式。例如所述第一指示信息指示所述网络设备的信道占用时间内的至少一个信道接入方式，以及指示所述信道占用时间外的至少一个信道接入方式。
这里，所述信道占用时间，可以是网络设备的一个信道占用时间；所述信道占用时间可以是网络设备根据FBE获得的信道占用时间，也可以是网络设备根据LBE获得的信道占用时间，或是网络设备根据其他方式获得的信道占用时间，本申请对此并不限定。
本发明实施例中，信道接入方式包括第一类型信道接入、第二类型信道接入和第三类型信道接入中的至少一种。
具体地，第一类型信道接入包括基于竞争窗口大小调整的随机回退的多时隙信道检测，例如Cat-4 LBT。第一类型信道接入包括不同的信道接入优先级，每个信道接入优 先级可以认为是一种信道接入方式。
第二类型信道接入包括单时隙信道检测，例如Cat-2 LBT。第二类型信道接入包括不同检测间隔的单时隙信道检测，具体地，Cat-2 LBT包括第一检测间隔例如检测间隔为25μs的Cat-2 LBT和第二检测间隔例如检测间隔为16μs的Cat-2 LBT。每个检测间隔下的Cat-2 LBT可以认为是一种信道接入方式。为了便于描述，在本申请中，检测间隔为25μs的Cat-2 LBT可以被称为第二类型信道接入第一信道接入方式，检测间隔为16μs的Cat-2 LBT可以被称为第二类型信道接入第二信道接入方式。
第三类型信道接入包括在空隙结束后不做信道检测而进行传输，例如Cat-1 LBT。
在本发明的一些实施例中，信道接入方式包括第二类型信道接入第一信道接入方式、第二类型信道接入第二信道接入方式、和第三类型信道接入中的至少一种。
作为示例而非限定，所述第一指示信息用于确定所述网络设备的信道占用时间内的至少一个信道接入方式，该至少一个信道接入方式包括第二类型信道接入第一信道接入方式、第二类型信道接入第二信道接入方式、和第三类型信道接入中的至少一种。
在本发明的另一些实施例中，信道接入方式除了包括第二类型信道接入第一信道接入方式、第二类型信道接入第二信道接入方式、和第三类型信道接入中的至少一种以外，还包括第一类型信道接入第一信道接入优先级、第一类型信道接入第二信道接入优先级、第一类型信道接入第三信道接入优先级和第一类型信道接入第四信道接入优先级中的至少一种，其中，第一类型信道接入第一信道接入优先级、第一类型信道接入第二信道接入优先级、第一类型信道接入第三信道接入优先级和第一类型信道接入第四信道接入优先级分别对应不同信道接入优先级，如上述表1所示。应理解，表1是一个示例，表1中的参数可以有修改，本申请对此并不限定。
作为示例而非限定，所述第一指示信息除了用于确定所述网络设备的信道占用时间内的至少一个信道接入方式，还用于确定所述信道占用时间外的至少一个信道接入方式，该至少一个信道接入方式除了包括第二类型信道接入第一信道接入方式、第二类型信道接入第二信道接入方式、和第三类型信道接入中的至少一种以外，还包括第一类型信道接入第一信道接入优先级、第一类型信道接入第二信道接入优先级、第一类型信道接入第三信道接入优先级和第一类型信道接入第四信道接入优先级中的至少一种。
可选地，所述第一指示信息用于确定目标信道接入方式组，所述目标信道接入方式组用于确定所述信道占用时间内的所述至少一个信道接入方式。举例来说，所述第一指示信息为“001”，则确定目标接入方式组为{Cat-1,16μs的Cat-2,25μs的Cat-2}。
可选地，所述目标信道接入方式组是根据第一参数确定的，所述第一参数是高层配置的或预设的；所述第一参数包括以下至少一种：所述目标信道接入方式组包括的至少一个信道接入方式、所述目标信道接入方式组包括的信道接入方式的个数和所述目标信道接入方式组包括的信道接入方式的最大个数。
可选地，所述目标信道接入方式组是高层配置的或预设的，所述第一指示信息用于从所述目标信道接入方式组中确定所述至少一个信道接入方式。例如，高层配置目标信道接入方式组为{Cat-1,16μs的Cat-2,25μs的Cat-2}，分别对应{00,01,10}，当第一指示信息为0010时，所述至少一个信道接入方式为Cat-1和25μs的Cat-2。
可选地，所述目标信道接入方式组的至少一个信道接入方式应用于网络设备的目标占用信道时间内的至少一个传输机会。
可选地，目标信道接入方式组与信道占用时间内的至少一个传输机会具有对应关系。例如，目标信道接入方式组中的第i个信道接入方式与信道占用时间内的至少一个传输机会中的第i个上行传输机会对应，其中，信道占用时间内的上行传输机会的个数小于或等于目标信道接入方式组中信道接入方式的个数。又例如，目标信道接入方式组 中的第i个信道接入方式与信道占用时间内的至少一个传输机会中的第i+1个传输机会对应，这主要是因为信道占用时间是网络设备LBT成功之后才确定的，信道占用时间中的第一个传输机会不需要进行信道接入方式的指示。
可选地，目标信道接入方式组中可以不包括网络设备传输机会(下行传输机会)的信道接入方式。这是因为，目标信道接入方式组是网络设备用于指示终端设备的传输对应的信道接入方式，网络设备的信道接入方式可以自行判断。在信道占用时间内网络设备传输对应的信道接入方式可以为第二类型信道接入第一信道接入方式，或第二类型信道接入第二信道接入方式。可选地，在信道占用时间内网络设备传输对应的信道接入方式不能为第三类型信道接入，即网络设备在信道占用时间内的每次传输开始前都需要做LBT。
可选地，目标信道接入方式组中可以包括信道占用时间的至少一个上行传输机会对应的信道接入方式。以图7所示的网络设备的信道占用时间内的传输机会的一种示意图为例，在网络设备的一个信道占用时间内包括4次传输机会，其中第一传输机会和第三传输机会为下行传输机会，第二传输机会和第四传输机会为上行传输机会，该目标信道接入方式组中包括第二传输机会对应的信道接入方式，或者说，第一指示信息中包括第二传输机会对应的信道接入方式的指示。
可选地，目标信道接入方式组中可以包括信道占用时间内的全部上行传输机会对应的信道接入方式。仍以图7为例，该目标信道接入方式组中包括第二传输机会和第四传输机会对应的信道接入方式；或者说，第一指示信息中包括第二传输机会和第四传输机会对应的信道接入方式的指示。
以图8所示的网络设备的信道占用时间内的传输机会的另一种示意图为例，在网络设备的信道占用时间内包括4次传输机会，其中第一传输机会为下行传输机会，第二传输机会、第三传输机会和第四传输机会为上行传输机会，该目标信道接入方式组中包括第二传输机会、第三传输机会和第四传输机会对应的信道接入方式，或者说，第一指示信息中包括第二传输机会、第三传输机会和第四传输机会对应的信道接入方式的指示。
可选地，目标信道接入方式组中可以包括信道占用时间内除第一次传输外的至少一个传输机会对应的信道接入方式。仍以图7为例，该目标信道接入方式组中包括第三传输机会对应的信道接入方式，或者说，第一指示信息中包括第三传输机会对应的信道接入方式的指示。
可选地，目标信道接入方式组中可以包括信道占用时间内除第一次传输外的全部传输机会对应的信道接入方式。仍以图7为例，该目标信道接入方式组中包括第二传输机会，第三传输机会和第四传输机会分别对应的信道接入方式，或者说，第一指示信息中包括第二传输机会，第三传输机会和第四传输机会对应的信道接入方式的指示。
可选地，目标信道接入方式组中可以包括信道占用时间内的至少一个侧行传输机会对应的信道接入方式。
可选地，目标信道接入方式组中可以包括信道占用时间内的全部侧行传输机会对应的信道接入方式。
本发明的一些实施例中，所述目标信道接入方式组是信道接入方式组集合中的一个信道接入方式组，所述信道接入方式组集合中包括至少一个信道接入方式组。
可选地，所述信道接入方式组集合是根据第二参数确定的，所述第二参数是高层配置的或预设的，所述第二参数包括以下至少一种：所述信道接入方式组集合中包括的至少一个信道接入方式组、所述信道接入方式组集合中包括的信道接入方式组的个数和所述信道接入方式组集合中包括的信道接入方式组的最大个数。
可选地，在所述信道接入方式组集合中包括至少两个信道接入方式组的情况下，所 述至少两个信道接入方式组中每个信道接入方式组包括的信道接入方式的个数可以是相同的。举例来说，每个信道接入方式组中包括的信道接入方式的个数为N，N为整数。N的取值是高层配置的或预设的。可选地，N取值为2或3。
作为示例，以N的取值是2为例，信道接入方式组集合如表2所示：该信道接入方式组集合中包括7个信道接入方式组，每个信道接入方式组中包括2个信道接入方式。例如，第一指示信息指示信道接入方式组的索引为5，那么终端设备在收到第一指示信息后，可以确定目标信道接入方式组包括的2个信道接入方式为第二类型信道接入第二信道接入方式和第二类型信道接入第一信道接入方式。

表2
可选地，在所述信道接入方式组集合中包括至少两个信道接入方式组的情况下，所述至少两个信道接入方式组中每个信道接入方式组包括的信道接入方式的个数可以是不相同的。
作为示例，以N的取值是3为例，信道接入方式组集合如表3所示：该信道接入方式组集合中包括8个信道接入方式组，所述8个信道接入方式组中至少两个信道接入方式组中包括的信道接入方式的个数不同。例如，第一指示信息指示信道接入方式组的索引为6，那么终端设备在收到第一指示信息后，可以确定目标信道接入方式组包括3个信道接入方式，且所述3个信道接入方式为第三类型信道接入，第二类型信道接入第二信道接入方式，和第二类型信道接入第一信道接入方式。

在一些实施例中，所述上行传输机会可以包括所述终端设备的上行传输机会，和/或，非所述终端设备的其他终端设备的上行传输机会。
在一些实施例中，所述侧行传输机会可以包括所述终端设备的侧行传输机会，和/或，非所述终端设备的其他终端设备的侧行传输机会。
步骤S202，终端设备根据所述第一指示信息，确定所述信道占用时间内的目标传输机会的第一信道接入方式。
在一些实施例中，传输机会的信道接入方式，可以指传输机会对应的信道接入方式，或者说，在传输机会开始前使用该信道接入方式进行信道检测。例如，所述目标传输机会的第一信道接入方式，可以指终端设备在目标传输机会开始前，以第一信道接入方式进行信道检测，并在信道检测成功的情况下，确定所述目标传输机会中的资源可以被该终端设备使用。所述目标传输机会用于传输目标信号或目标信道。终端设备可以通过目标传输机会上的资源传输目标信号或目标信道。其中，所述目标信号或目标信道包括下述中的至少一种：上行信号、上行信道、侧行信号和侧行信道。在所述目标信号或目标信道为侧行信号或侧行信道时，所述终端设备可以为D2D、V2X等系统中的终端设备。
在一些实施例中，所述目标传输机会是所述至少一个传输机会中的第i个传输机会，所述第一信道接入方式是所述至少一个信道接入方式中的第i个信道接入方式，i为正整数。举例来说，终端设备根据第一指示信息确定所述至少一个信道接入方式依次是信道接入方式A、信道接入方式B和信道接入方式C；所述目标传输机会为信道占用时间内的第二个上行传输机会，则终端设备确定在第二个上行传输机会前根据信道接入方式 B进行信道检测。
步骤S203，终端设备接收所述网络设备发送的第二指示信息，所述第二指示信息用于确定所述信道占用时间内的至少一个传输机会。
在一些实施例中，所述至少一个传输机会包括所述目标传输机会；即所述至少一个传输机会包括信道占用时间内的终端设备传输上行信道或上行信号的传输机会。
在一些实施例中，信道占用时间内包括的上行传输机会的最大个数、或信道占用时间内包括的上行传输机会的个数是由高层配置的或预设的。
在另一些实施例中，所述至少一个传输机会不包括信道占用时间内的网络设备传输下行信道或下行信号的传输机会。
可选地，所述第二指示信息可以是物理层信令，例如所述第二指示信息是DCI中包括的信息，其中所述DCI可以是公共控制信息或UE专用DCI。
可选地，所述第二指示信息可以是高层信令，例如所述第二指示信息是媒体接入控制(Media Access Control，MAC)控制单元(Control Element，CE)信令。
应理解，所述第二指示信息与所述第一指示信息可以是同一控制信息中包括的信息，也可以是不同控制信息中包括的信息，本申请对此并不限定。其中，所述控制信息可以是物理层信令例如是PDCCH中传输的DCI，也可以是高层信令例如是MAC CE信令。例如，包括第一指示信息和第二指示信息的控制信息是同一个控制信息，该控制信息是群组公共物理下行控制信道(Group Common-Physical Downlink Control CHannel，GC-PDCCH)中的DCI。
在一些实施例中，所述第二指示信息用于确定以下至少一种：
所述目标传输机会的起始符号和/或起始符号中的起始位置；
所述目标传输机会的结束符号和/或结束符号中的结束位置；
所述目标传输机会在所述信道占用时间内的位置；
所述目标传输机会的长度；
第一长度，所述第一长度包括用于传输所述第二指示信息的符号与所述目标传输机会的起始符号之间的时间距离，或，所述第一长度包括用于传输所述第二指示信息的时隙与所述目标传输机会的起始符号之间的时间距离；
第二长度，所述第二长度包括用于传输所述第二指示信息的传输机会的结束符号与所述目标传输机会的起始符号之间的时间距离，或，所述第二长度包括用于传输所述第二指示信息的传输机会的结束时隙与所述目标传输机会的起始符号之间的时间距离。
在一些实施例中，所述第二指示信息指示的信息根据第一子载波间隔确定，所述第一子载波间隔小于或等于所述目标传输机会对应的子载波间隔。其中，所述目标传输机会对应的子载波间隔是指，目标传输机会上传输上行信道或上行信号所使用的子载波间隔。可选地，第一子载波间隔是高层配置的。
在一些实施例中，所述信道占用时间包括的传输机会的个数是物理层指示的或高层配置的；和/或，所述信道占用时间包括的传输机会的最大个数是高层配置的或预设的。
在本申请实施例中，物理层指示可以指网络设备通过DCI指示。高层配置可以指网络设备通过高层信令指示，其中高层信令包括无线资源控制(Radio Resource Control，RRC)信令和/或MAC CE。
本发明实施例中，在执行步骤S202之前，所述方法还可以包括：
步骤S200，终端设备在所述信道占用时间开始前接收所述网络设备发送的第三指示信息；所述第三指示信息用于确定所述目标传输机会的信道接入方式为第二信道接入方式，所述第二信道接入方式和所述第一信道接入方式不同。
可选地，所述第二信道接入方式和所述第一信道接入方式不同，包括：所述第一信 道接入方式的优先级高于所述第二信道接入方式的优先级。
可选地，所述第一信道接入方式包括以下信道接入方式中的一种：第二类型信道接入第一信道接入方式、第二类型信道接入第二信道接入方式和第三类型信道接入。第二类型信道接入可以为第一类型信道接入；或者说，所述第一信道接入方式包括以下信道接入方式中的一种：检测间隙为25微秒的Cat-2 LBT、检测间隙为16微秒的Cat-2 LBT和Cat-1 LBT，第二类型信道接入可以为Cat-4 LBT。
可选地，所述第一信道接入方式为优先级为p1的Cat-4 LBT，所述第二信道接入方式为优先级为p2的Cat-4 LBT，其中，p1小于p2，或者说，p1的优先级高于p2的优先级。
在一些实施例中，当终端设备进行目标信号或目标信道例如PUSCH传输时，该终端设备确定使用第二信道接入方式例如Cat-4 LBT进行信道检测以确定是否能传输该PUSCH。进一步地，在该终端设备进行该PUSCH传输前，如果该终端设备根据网络设备发送的信息，确定该PUSCH属于网络设备的信道占用时间内的目标传输机会，并确定目标传输机会对应的信道接入方式为第一信道接入方式，那么该终端设备可以使用第一信道接入方式例如16微秒的Cat-2 LBT进行信道检测以确定是否能传输该PUSCH，或者说，终端设备将该PUSCH的信道接入方式由Cat-4 LBT切换为16微秒的Cat-2LBT。
在一些实施例中，终端设备根据第一指示信息确定目标信道接入方式组，根据第二指示信息确定信道占用时间内的至少一个传输机会，其中，目标信道接入方式组中的第i个信道接入方式与所述至少一个传输机会中的第i个上行传输机会对应。终端设备确定目标上行信号或目标上行信道为所述至少一个传输机会中的第j个上行传输机会，因此，终端设备确定目标信道接入方式组中的第j个信道接入方式为目标上行信号或目标上行信道的信道接入方式。
在一些实施例中，终端设备确定目标上行信号或目标上行信道的信道接入方式后，还包括：终端设备在该目标上行信号或目标上行信道传输前，使用该信道接入方式进行LBT，如果LBT成功，则终端设备可以进行该目标上行信号或目标上行信道的传输，如果LBT失败，则终端设备不能进行该目标上行信号或目标上行信道的传输。
作为示例，如表4所示，信道接入方式组集合中包括7个信道接入方式组，每个信道接入方式组中包括3个信道接入方式，可以用3比特来表示。可选地，由于Cat-1 LBT是在空隙结束后不做信道检测即传输；Cat-2 LBT是单时隙信道检测成功后才能传输，因此Cat-1 LBT不位于Cat-2 LBT之后。这主要是因为Cat-1 LBT可以认为不会丢掉信道的使用权(或者说，不会丢掉信道的传输机会)，Cat-2 LBT有一定概率丢掉信道的使用权(或者说，丢掉信道的传输机会，或者说，信道被其他设备占用)。

表4
下面仍以图7为例对本发明实施例的信息传输方法进行详细说明。信道占用时间内包括两个上行传输机会。终端设备在收到第一指示信息后，根据第一指示信息确定目标信道接入方式组，例如终端设备收到的第一指示信息为“001”，因此确定目标信道接入方式组为{Cat-1，16μs的Cat-2，25μs的Cat-2}。如果终端设备的目标上行信号或目标上行信道为第一个上行传输机会，那么终端设备确定目标上行信号或目标上行信道的信道接入方式为Cat-1 LBT。如果终端设备的目标上行信号或目标上行信道为第二个上行传输机会，那么终端设备确定目标上行信号或目标上行信道的信道接入方式为16μs的Cat-2 LBT。
仍以图8为例对本发明实施例的信息传输方法进行详细说明。信道占用时间内包括三个上行传输机会。终端设备在收到第一指示信息后，根据第一指示信息确定目标信道接入方式组，例如终端设备收到的第一指示信息为“001”，因此确定目标信道接入方式组为{Cat-1，16μs的Cat-2，25μs的Cat-2}。如果终端设备的目标上行信号或目标上行信道为第一个上行传输机会，那么终端设备确定目标上行信号或目标上行信道的信道接入方式为Cat-1 LBT。如果终端设备的目标上行信号或目标上行信道为第二个上行传输机会，那么终端设备确定目标上行信号或目标上行信道的信道接入方式为16μs的Cat-2LBT。如果终端设备的目标上行信号或目标上行信道为第三个上行传输机会，那么终端设备确定目标上行信号或目标上行信道的信道接入方式为25μs的Cat-2 LBT。
在一些实施例中，由于控制信息(至少包括第一指示信息)可以指示信道占用时间内的至少一个传输机会对应的信道接入方式，因此，当被调度使用第一类型信道接入例如Cat-4 LBT进行传输的终端设备，在收到该控制信息并判断目标信号或目标信道(例如目标上行信号或目标上行信道或目标侧行信号或目标侧行信道)属于该信道占用时间后，可以将信道接入类型由第一类型信道接入切换到第二类型信道接入；第一类型信道接入可以为Cat-4 LBT，第二类型信道接入可以为Cat-2 LBT。
在一些实施例中，网络设备向终端设备发送控制信息(至少包括第一指示信息)，指示信道占用时间内的至少一个空隙和该至少一个空隙对应的信道接入方式；因此，当被调度使用第一类型信道接入(如Cat-4 LBT)进行传输的终端设备在收到该控制信息，并判断待传输信号或信道属于该信道占用时间后，可以将信道接入类型由第一类型信道接入(如Cat-4 LBT)切换到第二类型信道接入(如Cat-2 LBT)。
本发明还提供了第二类型信道接入的实现方法。第二类型信道接入包括第一检测间隔的第二类型信道接入和/或第二检测间隔的第二类型信道接入。其中，所述第二类型信道接入可以为Cat-2 LBT，第一检测间隔可以是空隙大小为25μs，第二检测间隔可以是空隙大小为16μs。通常情况下，网络设备可以保证两次传输机会之间的空隙为上述值中的一种；具体可以通过传输占位信号、符号打孔、指示终端设备提前发送等方式实现。然而，对于终端设备来说，考虑到下行传输时延和上行发送的定时提前，终端设备确定的空隙大小可以小于网络设备预留的空隙大小；如图9所示的网络设备预留的空隙与终端设备确定的空隙示意图。
虽然在现有方案中，在网络设备的COT内发生的上行传输机会，如果上行传输机会的起始位置和下行传输机会的结束位置之间的空隙小于16μs，终端设备可以在空隙结束后立即进行该上行传输，但实际上，即使网络设备在上行传输机会的起始位置和下行传输机会的结束位置之间预留16μs的空隙，终端设备确定的空隙大小也可能小于16μs。因此，终端设备不能根据确定的空隙大小来确定信道接入方式，而是应该根据网络设备的指示或预设规则来确定信道接入方式。
可选地，预设规则包括：如果终端设备在上行传输机会中发送的信息包括：混合自动重传请求(Hybrid Automatic Repeat reQuest，HARQ)应答消息，和/或该上行传输机会的长度小于或等于预设值；则终端设备在空隙小于16μs的情况下可以在空隙结束后立即进行该上行传输。作为示例，该预设值可以为2个符号。
如果终端设备确定在网络设备的信道占用时间内的信道接入方式为第二类型信道接入(或者说，Cat-2 LBT)，那么可以通过以下方式中的一种来实现第二类型信道接入。
在一些可能的实现方式中，网络设备侧的空隙大小为16μs，终端设备侧确定的空隙大小为L1，其中，L1＜16μs。长度为L1的空隙包括第一子空隙和第二子空隙，第一子空隙位于第二子空隙前。第一子空隙和第二子空隙也可称为检测时隙。
在第一种实施例中，在第二子空隙内有4μs的能量检测低于预设门限，则LBT被认为成功；否则，LBT被认为失败。其中，第二子空隙大于或等于4μs。可选地，第一子空隙小于7μs，第二子空隙为9μs；或者，第一子空隙为7μs，第二子空隙小于9μs。可选地，第一子空隙大于或等于4μs。
在第二种实施例中，在第一子空隙内有4μs的能量检测低于预设门限，且在第二子空隙内有4μs的能量检测低于预设门限，则LBT被认为成功；否则，LBT被认为失败。其中，第一子空隙大于或等于4μs，第二子空隙大于或等于4μs。可选地，第一子空隙小于7μs，第二子空隙为9μs；或者，第一子空隙为7μs，第二子空隙小于9μs。
在第三种实施例中，在长度为L1的空隙内有4μs的能量检测低于预设门限，则LBT被认为成功；否则，LBT被认为失败。
在另一些可能的实现方式中，网络设备侧的空隙大小为25μs，终端设备侧确定的空隙大小为L2，其中，L2＜25μs。长度为L2的空隙包括第三子空隙和第四子空隙，第三子空隙位于第四子空隙前。在第三子空隙内有4μs的能量检测低于预设门限，且在第四子空隙内有4μs的能量检测低于预设门限，则LBT被认为成功；否则，LBT被认为失败。其中，第三子空隙为9μs，第四子空隙小于16μs；或第三子空隙小于16μs，第四子空隙为9μs。第三子空隙或第四子空隙也可以称为检测时隙。
在又一些可能的实现方式中，终端设备根据网络设备的指示或预设规则来预留进行LBT的空隙。例如网络设备指示终端设备进行第二检测间隔的第二类型信道接入，如图10所示，终端设备确定上行传输的起始时刻与上行传输机会中第一个携带有效数据的符号的起始时刻之间的时间长度为L3，L3大于或等于0，其中该L3时间长度内的资源可以用于终端设备发送占位信号，例如终端设备可以发送该第一个携带有效数据的符号的循环前缀(Cyclic Prefix，CP)延长部分。可选地，终端设备发送CP延长部分的时间长度为L4，其中，L4大于或等于0，且L4小于或等于L3。也就是说，终端设备可以使用第二检测间隔来进行第二类型信道接入，即该L3时间长度中的至少部分长度可以用于减小下行传输时延和上行发送的定时提前的影响。
上述实现第二类型信道接入的各种实现方式，均可以实现可变空隙大小情况下的信道接入。并且，终端设备根据网络设备的指示或预设规则来确定信道接入方式，而不是根据终端设备自身确定的空隙大小来确定信道接入方式，避免了网络设备和终端设备对信道接入方式的理解不一致。
本发明还提供了终端设备的发射功率从关到开调整的实现方法。终端设备在LBT过程中的最后一个检测时隙内，如果确定该检测时隙内有4μs例如任意4μs的能量检测低于预设门限，可以在该4μs能量检测结束后，从该检测时隙内开始进行发射功率从关到开的调整。假设终端设备的发射功率从关到开的调整时间为过渡周期，以终端设备在LBT过程中的最后一个检测时隙的长度为9μs为例，终端设备的过渡周期的示意图如图11所示。
应理解，在本申请的各种实施例中，上述个过程的序号的大小并不意味着执行顺序的先后，各过程的执行顺序应以其功能和内在逻辑确定，而不应对本申请实施例的实施过程构成任何限定。
