为了便于理解本申请实施例，首先，对申请实施例涉及的概念作简单介绍。
(1)传输方向
在本申请实施例中，传输方向至少包括上行传输(uplink，UL)和下行传输(downlink，DL)。该传输方向还可以包括空(empty)、未知的(unknown)以及预留(reserved)中的至少一种。其中，传输方向为上行传输是指终端设备向网络设备发送数据。传输方向为下行传输是指网络设备向终端设备发送数据。传输方向为空可以理解为：不进行数据传输。例如，假设子帧#1的传输方向为空，可以理解为不在子帧#1上传输数据，该子帧#1为空置资源，所述空置资源可以用于干扰测量，例如可用于交叉干扰链路测量。所述传输方向为unknown/reserved可理解为未知，主要用于前向兼容性考虑。例如，该传输方向为 unknown/reserved的子帧或时隙可以用于设备到设备(device-to-device，2D)通信，测量等。
(2)时间单元
时间单元是指一段时间长度，例如，该时间单元可以为一个子帧(subframe)、一个时隙(slot)、一个微时隙(mini-slot)或者一个符号等。该时间单元也可以是多个子帧、多个时隙、多个微时隙或者多个符号等。进一步地，该时间单元可以是通信系统中用于调度传输块的时间单位。例如，该时间单元可以为传输时间间隔(transmission time interval，TTI)。
(3)时间单元格式
时间单元格式用于指示时间单元包括的符号的传输方向。例如，假设时间单元为时隙，时隙格式用于指示一个时隙包括的符号的传输方向，该传输方向的详细说明可以参见上文的相关描述，例如，所述传输方向包括下行传输(DL)，上行传输(UL)，未知的(unknown)中的至少一种。可选地，可以预定义多种时间单元格式。
(4)时间单元格式信息
时间单元格式信息用于指示时间单元格式。例如，假设时间单元为时隙，时隙格式信息(slot format related information，SFI)可以用于指示一个时隙格式。
(5)时间单元格式类型
可以将时间单元格式划分为多种类型，即，多类时间单元格式。多类时间单元格式中的每种类型时间单元格式包括至少一个时间单元格式。其中，可以根据多种规律中的一种将时间单元格式进行划分。
作为可选地一例，可以按照时间单元包括的符号数量，将时间单元格式划分为多种类型。即，不同类型的时间单元格式对应的时间单元包括的符号的数量不同。也就是说，多类时间单元格式一一对应多个符号数量。
例如，该多类时间单元格式包括第Ⅰ类时间单元格式和第Ⅱ类时间单元格式，所述第Ⅰ类时间单元格式对应的时间单元包括的符号数量为N(N≥1)，所述第Ⅱ类时间单元格式对应的时间单元包括的符号数量为M(M≥1，且M≠N)。可选地，该N＝12，该M＝14。
作为可选地另一例，可以按照适用的业务类型，将时间单元格式划分为多种类型。即，不同类型的时间单元格式对应的业务类型不同。也就是说，多类时间单元格式一一对应多个业务类型。
例如，该多类时间单元格式包括第Ⅲ类时间单元格式和第Ⅳ类时间单元格式，所述第Ⅲ类时间单元格式适用于业务类型#A，所述第Ⅳ类时间单元格式适用于业务类型#B。可选地，业务类型#A为增强移动宽带(enhanced mobile broadBand，eMBB)业务，业务类型#超可靠性低时延通信(ultra-reliable and low latency communications，URLLC)业务。
作为可选地又一例，可以按照时间单元中上行符号和下行符号的个数的配比，将时间单元格式划分为多种类型。即，不同类型的时间单元格式对应的上下行符号个数的配比不同。也就是说，多类时间单元格式一一对应多种上下行符号个数的配比。
例如，该多类时间单元格式包括第Ⅴ类时间单元格式和第Ⅵ类时间单元格式，所述第Ⅴ类时间单元格式对应的时间单元中所有符号的传输方向相同，第Ⅵ类时间单元格式对应的时间单元中部分符号用于上行传输部分符号用于下行传输。
应理解，以上列举的分类方式仅为示例，还可以按照其它规律或规则进行分类，例如，还可以按照是否包括flexible符号进行分类，或时间单元中fixed符号与flexible符号的比例进行分类等多种分类方式。具体如何分类本申请实施例不在此限定。
(6)下行控制信息(downlink control information，DCI)格式(format)：
可以认为不同的DCI格式对应的DCI包括的比特位的数量不同。例如，DCI格式#1包括N(N≥1)个比特，DCI格式#2包括M(M≥1，且M≠N)个比特。该DCI格式也可以按照现有LTE的DCI format理解。
(7)带宽部分(bandwidth part，BP)
可以为频域上一段连续或非连续的资源。例如，一个带宽部分包含连续或非连续的K>0个子载波；或者，一个带宽部分为N>0个不重叠的连续或非连续的资源块(resource block，RB)所在的频域资源；或者，一个带宽部分为M>0个不重叠的连续或非连续的资源块组(resource block group，RBG)所在的频域资源，一个RBG包括P>0个连续的RB。一个带宽部分与一个特定的系统参数集合相关，所述系统参数集合包括子载波间隔和循环前缀(cyclic prefix，CP)的至少一种。
(8)组公共物理下行控制信道(group common physical downlink control channel，GC_PDCCH)
为了满足不同终端设备的实际需求，可以将多个终端设备划分为多个用户组。网络设备可以向某个用户组的终端设备发送GC_PDCCH，该用户组中的每个终端设备可以检测到(或解析)该GC_PDCCH，反之，不属于该用户组的终端设备不能检测到(或不能解析)该GC_PDCCH。例如，网络设备可以给一组终端设备配置相同的无线网络临时标识(radio network temporary identifier,RNTI)，所述RNTI用于检测其所对应的GC_PDCCH。可选地，用于指示时间单元格式的时间单元格式信息通过GC_PDCCH承载。
在5G中，网络设备可能发送至少两个时间单元格式信息其中，该至少两个时间单元格式信息一一对应两类时间单元格式。
例如，假设按照符号数量进行分类，网络设备可以发送时间单元格式信息#A和时间单元格式信息#B，该时间单元格式信息#A指示的时间单元格式对应12个符号，该时间单元格式信息#B指示的时间单元格式对应14个符号。
为了便于说明，可以将该至少两个时间单元格式信息记为“两类时间单元格式信息”。
对于一个终端设备而言，一个时间单元通过一类时间单元格式信息指示该时间单元的时间单元格式。但是，网络设备可能发送至少两类时间单元格式信息，也就是说，终端设备可能针对一个时间单元接收到至少两类时间单元格式信息。终端设备接收到该至少两类时间单元格式信息之后，无法确定该至少两类时间单元格式信息中哪个为目标时间单元格式信息。
例如，终端设备接收到时间单元格式信息#A和时间单元格式信息#B。终端设备根据时间单元格式信息#A确定时间单元#T包括的符号数量为12个，终端设备根据时间单元格式信息#B确定时间单元#T包括的符号数量为14个，终端设备无法确定该时间单元#T包括的符号数量为12个还是14个，从而导致终端设备的处理可能出错。
基于此，本申请实施例提出一种通信方法和通信装置，使能终端设备确定目标时间单元格式信息。
图1是适用于本申请实施例的应用场景的一例的示意性图。如图1所示，该应用场景包括网络设备101，该应用场景还包括位于网络设备101覆盖范围之内的终端设备102以及终端设备103。网络设备101可以与终端设备102和终端设备103进行通信。应理解，图1中仅以网络设备101覆盖范围内的两个终端设备作为示例。显然，网络设备101的覆盖范围内也可以有更多的终端设备102。
以下，结合图2对本申请实施例的用于确定传输方向的方法进行详细说明。
图2是根据本申请实施例的通信方法的一例的示意性交互图。应理解，图2示出了方法200的详细的步骤或操作，但这些步骤或操作仅是示例，本申请实施例还可以执行其它操作或仅执行图2中部分操作。
该方法200可以由网络设备和终端设备执行。其中，网络设备可以对应上述通信场景中的网络设备101，终端设备可以对应上述通信场景中的终端设备102或终端设备103。如图2所示，该方法200可以包括201、210以及220。
201、网络设备发送至少两类时间单元格式信息。
由上文可知，可以基于多种规律或规则将时间单元格式分为多种类型。例如，基于符号数量分类，不同类型的时间单元格式对应不同的符号数量，即，所述至少两类时间单元格式信息一一对应至少两种符号数量。又例如，基于业务类型适用的时间单元格式分类，不同类型的时间单元格式对应不同的业务类型，即，所述至少两类时间单元格式信息一一对应至少两种业务类型。
以下，为了便于说明，以基于符号数量分类为例，对本申请实施例进行说明，应理解，根据其他规律进行分类的相关具体描述可以参照按照符号数量进行分类的方式。
网络设备发送至少两类时间单元格式信息可以理解为：网络设备发送至少两个时间单元格式信息，且该至少两个时间单元格式信息指示的时间单元格式的类型不同。例如，网络设备发送时间单元格式信息#A和时间单元格式信息#B，该时间单元格式信息#A指示的时隙格式对应12个符号，该时间单元#B指示的时隙格式对应14个符号。
以下，为了便于说明，以时间单元为时隙为例，对本申请实施例进行说明。应理解，时间单元为其他类型(例如子帧)的详细说明可以参见时间单元为时隙的相关描述。还应理解，本申请实施例仅以SFI为例对本申请实施例进行说明，其他情况的时间单元格式信息(例如子帧格式信息)可以参见SFI的相关描述。
也就是说，该201可以包括：网络设备发送至少两类SFI。
210、网络设备向终端设备发送第一信息；相应地，终端设备接收该第一信息。
具体地，网络设备通过向终端设备发送第一信息，向终端设备指示所述终端设备的目标SFI，其中，所述目标SFI属于所述至少两类SFI中的一类。
220、所述终端设备根据所述第一信息，在所述至少两类SFI中确定目标SFI。
在本申请实施例中，终端设备可以通过接收第一信息，确定目标SFI，使能终端设备确定目标SFI。进一步地，该方案有利于避免终端设备使用不适当的SFI确定时隙格式。
可选地，该至少两类SFI可以通过至少两个GC_PDCCH承载，其中，该至少两类SFI和至少两个GC_PDCCH一一对应。可选地，该至少两类SFI也可以通过一个GC_PDCCH承载。
其中，该220可以以下包括多种方式中的一种。
方式#1
该220可以包括：
终端设备根据所述第一信息，在所述至少两类SFI中检测所述目标SFI。
具体地，终端设备支持所述至少两类SFI的时隙格式(例如，终端设备支持12符号和14符号的时隙格式)。在此情况下，终端设备可能接收到至少两类SFI，为了避免该情况的发生，终端设备可以根据第一信息，确定怎样检测SFI，以便于终端设备可以根据该目标SFI的类型检测所述目标SFI。
作为可选地一例，终端设备根据所述第一信息，在所述至少两类SFI中检测所述目标SFI可以包括以下几种中的至少一种：
1)所述终端设备根据所述第一信息，确定所述目标SFI对应的第一资源，使用所述第一资源检测所述目标SFI。
具体地，不同类型的SFI可以对应不同的资源。终端设备可以根据第一信息，确定第一资源，终端设备使用该第一资源检测目标SFI。可选地，该资源可以包括下行控制信息资源集合(control resource set，CORSET)、频域资源(例如，BP)以及加扰序列(例如，RNTI)中的至少一种。应理解，加扰序列属于加扰资源。
例如，CORSET#A用于传输第一类型SFI，CORSET#B用于传输第二类型SFI，终端设备可以根据第一信息，确定CORSET#A或CORSET#B。网络设备在CORSET#A上发送一个SFI(该SFI属于第一类型SFI)，在CORSET#B上发送一个SFI(该SFI属于第二类型SFI)，终端设备可以在确定的CORSET上检测目标SFI。例如，假设终端设备根据第一信息，确定CORSET#A，终端设备在CORSET#A上检测目标SFI(应理解，该目标SFI属于第一类型SFI)，终端设备不在CORSET#B上检测SFI。
应理解，若不同类型的SFI可以通过相同的资源承载，在此情况下，终端设备可以结合其他信息(例如，本申请实施例公开的其他用于确定SFI的信息或参量)确定目标SFI。
2)所述终端设备根据所述第一信息，确定所述目标SFI对应的第一DCI格式，根据所述第一DCI格式检测所述目标SFI。
具体地，不同类型的SFI可以对应不同的DCI格式。应理解，SFI对应的DCI格式可以是：用于承载SFI的DCI的DCI格式。为了便于说明，可以将该“用于承载SFI的DCI的DCI格式”记为“用于承载SFI的DCI格式”。终端设备可以根据第一信息，确定第一DCI格式，终端设备使用第一DCI格式检测所述目标SFI。其中，终端设备根据第一DCI格式检测所述目标SFI，可以理解为：终端设备根据第一DCI格式检测所述目标SFI所在的DCI，即，终端设备根据第一DCI格式尝试检测携带SFI的DCI，若终端设备根据该第一DCI格式可以检测出一个SFI，终端设备确定该检测到的SFI为目标SFI，若终端设备根据第一DCI格式无法检测出(无法解析)接收的SFI，终端设备确定该SFI非目标SFI。
例如，假设携带第一类型SFI的DCI格式为DCI格式#1，携带第二类型SFI的DCI格式为DCI格式#2。若终端设备根据第一信息，确定DCI格式#1，终端设备根据DCI格式#1检测SFI。
3)所述终端设备根据所述第一信息，确定所述目标SFI对应的第一资源以及第一DCI格式，根据所述第一资源以及所述第一DCI格式检测所述目标SFI。
应理解，3)的详细描述可以参见上文的相关说明，为了简洁不在此赘述。
也就是说，在方式#1中，终端设备根据第一信息，有目标的检测SFI。采用该方式#1能够避免终端设备检测无效SFI，有利于提高终端设备检测SFI的效率。
应理解，“无效SFI”可以理解为不适用于该终端设备的SFI，目标SFI可以理解为适用于该终端设备的SFI，也可以将该目标SFI记为“有效SFI”。
方式#2
该220可以包括：
所述终端设备根据所述第一信息，在检测到的所述至少两类SFI中确定目标SFI。
由上文可知，终端设备针对一个时隙，可能检测出至少两类SFI。作为可选地一例，终端设备可以以下几种方式中的至少一种，从该至少两类SFI中确定目标SFI。
1)所述终端设备根据所述第一信息，确定所述目标SFI对应的第一资源，所述终端设备确定所述至少两类SFI中通过所述第一资源传输的SFI为所述目标SFI。
具体地，不同类型的SFI可以对应不同的资源，终端设备可以根据第一信息，确定第一资源，终端设备确定根据第一资源检测到的SFI为目标SFI。其中，该资源的相关描述可以参见上文的相关说明。
例如，CORSET#A用于传输第一类型SFI，CORSET#B用于传输第二类型SFI，网络设备在CORSET#A上发送一个SFI(该SFI属于第一类型SFI)，在CORSET#B上发送一个SFI(该SFI属于第二类型SFI)；相应地，终端设备在CORSET#A上接收一个SFI，在CORSET#B上接收一个SFI。若终端设备可以根据第一信息，确定CORSET#A，终端设备确定在CORSET#A上接收的SFI为目标SFI(应理解，该目标SFI属于第一类型SFI)。该目标SFI可以认为是有效SFI，在CORSET#B上接收的SFI为无效SFI。
2)所述终端设备根据所述第一信息，确定所述目标SFI对应的第一DCI格式，所述终端设备确定所述至少两类SFI中通过所述第一DCI格式检测出的SFI为所述目标SFI。
具体地，不同类型的SFI可以对应不同的DCI格式，终端设备可以根据第一信息，确定第一DCI格式，终端设备确定通过第一DCI格式检测出的SFI为目标SFI。其中，该格式的相关描述可以参见上文的相关说明。
例如，假设携带第一类型SFI的DCI格式为DCI格式#1，携带第二类型SFI的DCI格式为DCI格式#2，网络设备使用DCI格式#1发送一个SFI(该SFI属于第一类型SFI)，使用DCI格式#2发送一个SFI(该SFI属于第二类型SFI)；相应地，终端设备根据DCI格式#1检测出一个SFI，根据DCI格式#2检测出一个SFI，终端设备可以根据第一信息，确定DCI格式#1或DCI格式#2。若终端设备根据第一信息确定DCI格式#1，终端设备确定根据DCI格式#1检测出的SFI为目标SFI，根据DCI格式#1无法检测出(或解析出)的SFI为无效SFI。
3)所述终端设备根据所述第一信息，确定所述目标SFI对应的第一资源以及第一DCI格式，所述终端设备确定所述至少两类SFI中通过所述第一资源传输且通过所述第一DCI格式检测出的SFI为目标SFI。
应理解，3)的详细描述可以参见上文的相关说明，为了简洁不在此赘述。
4)所述终端设备根据所述第一信息，确定所述目标SFI包括第一标识信息，所述终端设备确定所述至少两类SFI中包括所述第一标识信息的SFI为所述目标SFI，可选地，标识信息用于标识SFI类型。
具体地，不同类型的SFI可以对应不同的标识信息。可选地，该标识信息可以用于标识SFI类型。终端设备可以根据第一信息，确定第一标识信息，终端设备确定包括第一标识信息的SFI为所述目标SFI。其中，该标识信息可以通过多种方式体现。
例如，终端设备支持12符号长度和14符号长度的时隙格式，该SFI可以包括四个比特位“Ixxx”。其中，该第一个比特位“I”为用于标识该SFI类型的标识信息(可选地，可以将该标识信息所在的比特位记为FLAG位)，该比特位“xxx”可以为时隙格式的索引。例如，“I＝1”标识12符号长度，“I＝0”标识14符号长度，若终端设备接收的SFI的四个比特位为“1xxx”，终端设备确定该SFI对应的时隙格式为12符号长度。若终端设备接收的SFI的四个比特位为“0xxx”，终端设备可以确定该SFI对应的时隙格式为14符号长度。应理解，若时隙格式类型的数量大于2，可以设定至少两个比特以用于标识每一种时隙格式类型。
仍以上文中终端设备支持12符号长度和14符号长度的时隙格式为例，假设终端设备接收到两个SFI，该两个SFI的四个比特位分别为“1xxx”和“0xxx”。终端设备根据第一信息，确定12符号长度，终端设备可以确定“1xxx”为目标SFI(即有效SFI)，“0xxx”为无效SFI。
对于方式#1而言，终端设备可以根据第一信息，有目标的检测SFI。也就是说，针对方式#1，终端设备可以先执行210再执行201。
针对方式#2而言，终端设备先检测到至少两类SFI，终端设备根据第一信息，从该至少两类SFI中确定目标SFI。也就是说，针对方式#2，终端设备可以先执行201，再执行210。
应理解，在方式#2中，终端设备可以检测出多类SFI。基于该多类SFI，可以包括以下情况中的至少一种。
情况#1
终端设备根据第一信息，确定第一资源，该多类SFI中一个SFI通过第一资源传输，其他类SFI通过其他资源传输，该通过第一资源传输的SFI为有效SFI(即目标SFI)。通过其他资源传输的SFI为无效SFI，可选地，终端设备可以丢弃无效SFI。

由上文可知，用于传输SFI的资源、用于承载SFI的DCI格式以及用于标识SFI的标识信息中的至少一种与SFI类型可以具有对应关系，基于此，可选地，网络设备可以使用 至少两个资源一一对应发送所述至少两类时间单元格式信息；或网络设备可以使用至少两个DCI格式一一对应发送所述至少两类时间单元格式信息；或网络设备可以使用至少两个标识信息一一对应发送所述至少两类时间单元格式信息，所述至少两类时间单元格式信息中每类时间单元格式信息包括对应的标识信息。
以上，描述了终端设备可以根据第一信息，从至少两类SFI中获取目标SFI，以下，详细说明本申请实施例的第一信息。
可选地，该第一信息可以通过物理层信令或高层信令承载。高层信令可以包括无线资源控制(radio resource control，RRC)信令或介质访问控制(medium access control，MAC)信令。该第一信息还可以通过广播消息承载。其中，该广播消息可以是系统消息，其中，该系统消息可以包括主系统信息块(master information block，MIB)消息，或系统信息块(system information block，SIB)消息，其他系统信息(remaining system information，RMSI)。
终端设备可以根据第一信息，获取目标SFI，也就是说，网络设备可以通过向终端设备发送第一信息，向终端设备指示目标SFI。其中，网络设备可以通过多种方式向终端设备指示目标SFI。
显式指示：
可选地，第一信息用于指示某个类型的SFI、指示用于传输目标SFI的资源或指示用于承载目标SFI的DCI格式等，终端设备接收到第一信息之后，可以按照上文方式#1或方式#2的方法获取目标SFI。
隐式指示：
(1)作为可选地一例，第一信息可以用于为终端设备配置至少一个参量，终端设备可以根据该配置的参量确定目标SFI。该至少一个参量可以包括业务类型、CP以及子载波间隔中的至少一种。也就是说，终端设备可以根据第一信息配置的业务类型、CP以及子载波间隔确定目标SFI。换句话说，该目标SFI与第一信息配置的业务类型、CP以及子载波间隔与目标SFI对应。以下，详细描述终端设备如何根据该至少一个参量确定目标SFI。
1)业务类型。
即，第一信息可以用于为所述终端设备配置业务类型，也就是说，第一信息包括用于为所述终端设备配置业务类型的信息。
具体地，不同的业务类型可以对应不同类型的SFI。终端设备可以根据第一信息配置的业务类型，确定目标SFI(确定目标SFI的类型)。为了便于说明，可以将第一信息配置的业务类型记为“第一业务类型(或目标业务类型)”
例如，业务类型#A对应第一类型SFI，业务类型#B对应第二类型SFI，第一信息为终端设备配置的第一业务类型为业务类型#A，终端设备根据该业务类型#A可以确定该终端设备的目标SFI的类型为第一类型SFI，从而终端设备可以基于第一类型SFI获取目标SFI。
进一步地，业务类型与SFI类型具有对应关系，由上文可知，用于传输SFI的资源、用于承载SFI的DCI格式以及标识SFI的标识信息中的至少一种与SFI类型具有对应关系。作为可选地一例，可以直接建立用于传输SFI的资源、用于承载SFI的DCI格式以及标识SFI的标识信息中的至少一种与业务类型的对应关系。为了便于说明，可以将该对应关系 记为对应关系#a。
即，终端设备接收到第一信息之后，可以确定第一业务类型，根据该第一业务类型对应的资源和/或根据该第一业务类型对应的DCI格式获取目标SFI。
作为可选地一例，该对应关系#a可以通过第一映射表体现。例如，该第一映射表可以记录：业务类型#x对应用于传输SFI的资源#y，业务类型#x对应用于承载SFI的DCI格式#z中的至少一种。
作为可选地另一例，该对应关系#a可以通过第一门限体现。例如，业务类型#A对应的资源的编号大于或等于第一门限，业务类型#B对应的资源的编号小于第一门限。例如，假设该用于传输SFI的资源BP，该第一门限为4，业务类型#A对应BP编号大于或等于4的BP，业务类型#B对应BP编号小于4的BP。
需要说明的是，若一种业务类型对应多个用于传输SFI的资源或多个用于承载SFI的格式，在此情况下，终端设备仅根据第一业务类型可能无法确定目标SFI，此时，终端设备可以结合其他信息(例如，本申请实施例涉及的用于确定目标SFI的其他信息)确定目标SFI。
2)CP
即，第一信息包括用于为所述终端设备配置CP的信息，也就是说，第一信息可以用于为所述终端设备配置CP。
可选地，目前CP包括常规CP(normal cyclic prefix，NCP)以及扩展CP(extended cyclic prefix，ECP)。
具体地，不同类型的CP可以对应不同类型的SFI。可选地，NCP对应14符号数量的SFI，ECP对应12符号数量的SFI。终端设备可以根据第一信息配置的CP，确定目标SFI(确定目标SFI的类型)。为了便于说明，可以将第一信息配置的CP记为“第一CP(或目标CP)”。
例如，NCP对应第一类型SFI，ECP对应第二类型SFI。第一信息为终端设备配置的第一CP为NCP，终端设备根据该NCP可以确定该终端设备的目标SFI的类型为第一类型SFI，从而终端设备可以基于第一类型SFI获取目标SFI。
进一步地，CP与SFI类型具有对应关系，由上文可知，用于传输SFI的资源、用于承载SFI的DCI格式以及标识SFI的标识信息中的至少一种与SFI类型具有对应关系。作为可选地一例，可以直接建立用于传输SFI的资源、用于承载SFI的DCI格式以及标识SFI的标识信息中的至少一种与CP的对应关系。为了便于说明，可以将该对应关系记为对应关系#b。
即，终端设备接收到第一信息之后，可以确定第一CP，根据该第一CP对应的资源和/或根据该第一CP对应的DCI格式获取目标SFI。
作为可选地一例，该对应关系#b可以通过第二映射表体现。例如，该第二映射表可以记录：CP类型#x对应资源#y，CP类型#x对应格式#z中的至少一种。
作为可选地另一例，该对应关系#b可以通过第二门限体现。该第二门限的详细说明可以参见上文第一门限的相关描述，为了简洁不在此赘述。
同上文描述的类似，若一个CP类型对应多个资源或多个格式，终端设备仅根据第一CP无法确定目标SFI，此时终端设备可以结合其他信息(例如，上文中其中用于确定SFI 的信息)确定目标SFI。
例如，第一CP对应资源#a和资源#b，第一业务类型对应资源#a和资源#c，终端设备可以根据第一业务类型和第一CP，根据资源#a检测目标SFI，或确定根据资源#a检测到的SFI为目标SFI。
3)子载波间隔
即，第一信息包括用于为所述终端设备配置子载波间隔的信息，也就是说，第一信息可以用于为所述终端设备配置子载波间隔。
具体地，不同的子载波间隔可以对应不同类型的SFI。终端设备可以根据第一信息配置的子载波间隔，确定目标SFI(确定目标SFI的类型)。为了便于说明，可以将第一信息配置的子载波间隔记为“第一子载波间隔(或目标子载波间隔)”。
例如，子载波间隔#A对应第一类型SFI，子载波间隔#B对应第二类型SFI。第一信息为终端设备配置的第一子载波间隔为子载波间隔#A，终端设备根据该子载波间隔#A可以确定该终端设备的目标SFI的类型为第一类型SFI，从而终端设备可以基于第一类型SFI获取目标SFI。
进一步地，子载波间隔与SFI类型具有对应关系，由上文可知，用于传输SFI的资源、用于承载SFI的DCI格式以及标识SFI的标识信息中的至少一种与SFI类型具有对应关系。作为可选地一例，可以直接建立用于传输SFI的资源、用于承载SFI的DCI格式以及标识SFI的标识信息中的至少一种与子载波间隔的对应关系。为了便于说明，可以将该对应关系记为对应关系#c。
即，终端设备接收到第一信息之后，可以确定第一子载波间隔，根据该第一子载波间隔对应的资源和/或根据该第一子载波间隔对应的DCI格式获取目标SFI。
示例地，该对应关系#c可以通过第三映射表体现。例如，该第三映射表可以记录：子载波间隔类型#x对应资源#y，子载波间隔类型#x对应格式#z中的至少一种。
示例地，该对应关系#c可以通过第三门限体现。例如，大于或等于第三门限的子载波间隔对应资源#a，小于第三门限的子载波间隔对应资源#b。例如，假设第三门限为60kHz。大于或等于60kHz的子载波间隔对应资源#a，小于60kHz的子载波间隔对应资源#b。该第三门限的相关描述也可以参见上文第一门限的相关描述，为了简洁不在此赘述。
基于以上所述，可选地，业务类型、CP和子载波间隔中的至少一种与用于传输时间单元格式信息的资源、用于承载时间单元格式信息的DCI格式以及用于标识时间单元格式信息的标识信息中的至少一种具有对应关系，为了便于说明，可以将该对应关系记为“第一对应关系”，终端设备可以根据第一信息的配置以及第一对应关系，获取目标SFI。
(2)作为可选地另一例，该第一信息可以为调度所述终端设备的第一下行控制信息DCI，也就是说，终端设备可以根据第一DCI确定目标SFI。
应理解，该第一DCI为用于调度终端设备的DCI，该第一DCI与上文中的用于传输SFI的DCI为不同的DCI。进一步地，可以将第一DCI理解为专用于调度终端设备的DCI(或针对该终端设备的DCI)，可以将用于传输SFI的DCI理解为专用于多个终端设备的DCI(或针对某个用户组的DCI)。为了便于说明，可以将用于调度终端设备的DCI记为“用户专用DCI(UE specific DCI)”，将用于传输SFI的DCI记为“组公共DCI(group common DCI)”。
可选地，终端设备根据第一DCI确定目标SFI可以包括：终端设备根据所述第一DCI的DCI格式和所述第一DCI分配的频域资源中的至少一种，确定所述目标SFI。换句话说，所述第一DCI的DCI格式和所述第一DCI分配的频域资源中的至少一种与所述目标SFI对应。以下，详细描述终端设备如何根据所述第一DCI的DCI格式和所述第一DCI分配的频域资源中的至少一种，确定所述目标SFI。
1)第一DCI的DCI格式
具体地，用户专用DCI的不同的DCI格式可以对应不同类型的SFI。终端设备可以根据第一DCI的DCI格式，确定目标SFI(确定目标SFI的类型)。例如，若第一DCI的DCI格式为DCI格式#Ⅰ，终端设备根据第一DCI确定目标SFI属于DCI格式#Ⅰ对应的SFI类型。若第一DCI的DCI格式为DCI格式#Ⅱ，终端设备根据第一DCI确定目标SFI属于DCI格式#Ⅱ对应的SFI类型。
进一步地，用户专用DCI的DCI格式与SFI类型具有对应关系，由上文可知，用于传输SFI的资源、用于承载SFI的DCI格式(即组公共DCI的DCI格式)以及标识SFI的标识信息中的至少一种与SFI类型具有对应关系。作为可选地一例，可以直接建立用于传输SFI的资源、用于承载SFI的DCI格式以及标识SFI的标识信息中的至少一种与用户专用DCI的DCI格式的对应关系。为了便于说明，可以将该对应关系记为对应关系#d。
即，终端设备接收到第一信息之后，可以确定第一DCI的DCI格式，根据该第一DCI的DCI格式对应的资源和/或使用该第一DCI的DCI格式对应的组公共DCI的DCI格式获取目标SFI。
作为可选地一例，该对应关系#d可以通过第四映射表体现。例如，该第一映射表可以记录：用户专用DCI的DCI格式#x对应用于传输SFI的资源#y，用户专用DCI的DCI格式#x对应组公共DCI的DCI格式#z。
作为可选地另一例，该对应关系#d可以通过第四门限体现。该第五门限的详细说明可以参见上文第一门限的相关描述，为了简洁不在此赘述。
需要说明的是，与上文描述的类似，在某些情况下，终端设备仅根据第一DCI的DCI格式有可能无法获取SFI，此时，终端设备可以结合其他信息(例如，本申请实施例涉及的用于确定目标SFI的其他信息)确定目标SFI。
2)第一DCI分配的频域资源(例如，BP)。
具体地，用户专用DCI分配的不同的频域资源可以对应不同类型的SFI。终端设备可以根据第一DCI分配的频域资源，确定目标SFI(确定目标SFI的类型)。例如，若第一DCI分配频域资源#A，终端设备根据第一DCI确定目标SFI属于频域资源#A对应的SFI类型。若第一DCI分配频域资源#B，终端设备根据第一DCI确定目标SFI属于频域资源#B对应的SFI类型。
进一步地，用户专用DCI分配的频域资源与SFI类型具有对应关系，由上文可知，用于传输SFI的资源、用于承载SFI的DCI格式以及标识SFI的标识信息中的至少一种与SFI类型具有对应关系。作为可选地一例，可以直接建立用于传输SFI的资源、用于承载SFI的DCI格式以及标识SFI的标识信息中的至少一种与用户专用DCI分配的频域资源的对应关系。为了便于说明，可以将该对应关系记为对应关系#f。
即，终端设备接收到第一信息之后，可以确定第一DCI分配的频域资源，根据该第一 DCI分配的频域资源对应的资源和/或使用该第一DCI分配的频域资源对应的DCI格式获取目标SFI。
作为可选地一例，该对应关系#f可以通过第五映射表体现。例如，该第一映射表可以记录：用户专用DCI分配的频域资源#x对应用于传输SFI的资源#y，用户专用DCI分配的频域资源#x对应组公共DCI的DCI格式#z。
作为可选地另一例，该对应关系#f可以通过第五门限体现。该第五门限的详细说明可以参见上文第一门限的相关描述，为了简洁不在此赘述。
基于以上所述，可选地，用于调度终端设备的DCI的DCI格式以及用于调度终端设备的DCI分配的频域资源中的至少一种与用于传输时间单元格式信息的资源、用于承载时间单元格式信息的DCI格式以及用于标识时间单元格式信息的标识信息中的至少一种具有对应关系，为了便于说明，可以将该对应关系记为“第二对应关系”，终端设备可以根据第一DCI以及第二对应关系，获取目标SFI。
也就是说，可选地，在本申请实施例中，业务类型、CP、子载波间隔、用于调度终端设备的DCI的DCI格式以及用于调度终端设备的DCI分配的频域资源中的至少一种与用于传输SFI(时间单元格式信息)的资源、用于承载SFI(时间单元格式信息)的DCI格式以及用于标识SFI(时间单元格式信息)的标识信息中的至少一种具有对应关系。终端设备可以基于该对应关系以及第一信息，获取目标SFI。
作为可选地另一例，若该至少两类SFI位于相同的组公共DCI中。终端设备可以根据第一信息确定目标SFI的位置。
例如，如表1所示，假设组公共DCI包括3个块(block)，每个block为一个SFI，终端设备可以根据该第一信息从该3个block中确定目标block，从目标block中获取目标SFI，并根据目标SFI包括的标识信息确定该目标SFI的类型。
block0 block1 block2
1000 0000 1111
如表1所示，终端设备可以根据该第一信息确定目标block，并根据该目标block中目标SFI携带的标识信息确定对应的SFI类型。
也就是说，终端设备可以根据第一信息确定目标SFI所在的字段(或比特)的位置，以便于终端设备根据第一信息，获取目标SFI。
以上结合图2描述了根据本申请实施例的通信方法，以下，结合图3至图6描述根据本申请实施例的通信设备。
