由于URLLC业务有超低时延的要求，因此网络设备有可能会将URLLC业务传输调度到已分配给eMBB业务传输的资源上。又由于URLLC业务有超高可靠性的要求，因此需要降低eMBB业务的传输对URLLC业务传输的影响和干扰。网络设备常通过向传输eMBB业务的终端设备发送上行传输(Uplink，UL)取消指示信令(Cancellation Indication，CI)，取消或中断终端设备已经进行的上行eMBB业务，以实现这一目的。
相关技术中，终端设备设备在接收到CI时，对需要取消上行传输的具体资源并不明确，亟待确定。

下面先结合附图1至15，对应用于终端设备的取消上行传输的方法进行说明。
图1示出了根据本申请一个实施例的取消上行传输的方法，应用于终端设备。如图1所示，该方法可以包括如下步骤：
步骤101、在接收到上行传输取消指令(Uplink Cancellation Indication， UL CI)时，确定第一起始时刻，所述第一起始时刻为参考时间区域的起始时刻。
参考时间区域(reference time region)可以是预先设定的用于确定取消上行传输的参考时域资源。参考时间区域通常由第一起始时刻和总长度来确定，下文会结合具体的实施例对确定第一起始时刻和总长度的方式进行说明。
在步骤101中，具体可以基于上行传输取消指令的接收时刻和预设时间间隔，确定所述第一起始时刻。更为具体的，可以将从所述上行传输取消指令的接收时刻开始经过所述预设时间间隔之后的第一个时隙或第一个符号，确定为所述第一起始时刻。
UL CI的接收时刻可以是接收携带所述UL CI的下行控制信道(PDCCH)的时隙(slot)，或者UL CI的接收时刻可以是UE接收携带所述UL CI的PDCCH的最后一个时间符号(symbol)，以下简称符号。
其中，预设时间间隔可以基于下列方式中的一种来确定：第一种方式，基于所述上行传输取消指令中包含的用于指示所述预设时间间隔的信息，确定所述预设时间间隔；第二种方式，基于用于配置所述预设时间间隔的高层信令(例如，无线资源控制(Radio Resource Control，RRC))，确定所述预设时间间隔；或第三种方式，基于第一预设值确定所述预设时间间隔，等等。
对于第一种方式而言，UE可以基于UL CI中指示的时延(offset)来确定上述预设时间间隔，该时延也可以等于K3，K3是相对于UL CI的接收时刻的时长，K3的单位可以是时隙(slot)或符号(symbol)。K3的具体长度与子载波间隔(subcarrier spacing，SCS)有关。可以预先由网络设备通过RRC在UE中配置一个K3集合，并在UL CI中指示K3的实际取值。
可选地，如果UL CI是发送给一组UE的，UL CI中指示的K3的长度需要保证收到该UL CI的各UE均有足够的取消时间(cancellation time)，该取消时间可以理解为是UE取消上行传输的处理时间。
并且，在第一种方式中，可以将从UL CI的接收时刻开始经过K3之后的第一个时隙的边界(boundary)或第一个符号，确定为上述第一起始时刻。
具体来说，在给定的SCS下，第一起始时刻可以是从UL CI的接收时刻开始经过K3时隙或符号之后的第一个时隙的边界(boundary)。
例如，假设UL CI指示K3＝1个时隙，参考时间区域的总长度为X个时隙，UE在时隙n接收到UL CI，则UE可以将时隙n+1结束的时刻作为第一起始时刻，相应的，将时隙n+1之后开始的X个时隙确定为参考时间区域。
又如，假设UL CI指示K3＝7个符号，参考时间区域的总长度为X个时隙，UE在时隙n的符号i(i为一个时隙内符号的编号，i<7,i＝0～13)接收到UL CI，则UE可以将时隙n+1结束的时刻作为第一起始时刻，相应的，将时隙n+1之后开始的X个时隙确定为参考时间区域。
再如，假设UL CI指示K3＝14个符号，参考时间区域的总长度为X个时隙，UE在时隙n的符号i(i＝0～13)接收到UL CI，则UE可以将时隙n+2结束的时刻作为第一起始时刻，相应的，将时隙n+2之后开始的X个时隙确定为参考时间区域。
或者，在给定的SCS下，第一起始时刻可以是从UL CI的接收时刻开始经过K3时隙或符号之后的第一个符号。
例如，假设UL CI指示K3＝7个符号，参考时间区域的总长度为X个时隙，UE在时隙n的符号i(i<7，i＝0～13)接收到UL CI，则UE可以将时隙n的符号i再加7个符号之后的第一个符号确定为第一起始时刻，相应的，将时隙n的符号i+7个符号之后开始的X个时隙确定为参考时间区域。
再如，假设UL CI指示K3＝14个符号，参考时间区域的总长度为X个时隙，UE在时隙n的符号i(i＝0～13)接收到UL CI，则UE可以将时隙n+1的符号i之后的第一个符号确定为第一起始时刻，相应的，将时隙n+1的符号i之后开始的X个时隙确定为参考时间区域。
又如，假设UL CI指示K3＝14个符号，参考时间区域的总长度为Y个符号，UE在时隙n的符号i(i＝0～13)接收到UL CI，则UE可以将时隙n+1的符号i之后的第一个符号确定为第一起始时刻，相应的，将时隙n+1的符号i之后开始的Y个符号确定为参考时间区域。
对于第二种方式而言，UE可以基于高层信令(例如RRC)配置的参考时延(reference offset)来确定上述预设时间间隔，该参考时延也可以是相对于UL CI的接收时刻的时长，参考时延的单位可以是时隙(slot)或符号(symbol)。参考时延的具体长度与子载波间隔(subcarrier spacing，SCS)有关。
可选地，如果UL CI是发送给一组UE的，则高层信令(例如RRC)配置的参考时延的长度需要保证收到该UL CI的各UE均有足够的取消时间，该取消时间可以理解为是取消上行传输的处理时间。
进一步地，网络设备可以选择将UL CI发送给一组处理能力相同的UE，例如发送给一组最小取消时间长度相同，以及上行定时提前(timing advance，TA)的值相同的UE，这样高层信令可以向该组中的各UE配置相同的参考时延，这对网络设备来说更为简单易行。如果网络设备将UL CI发送给一组处理能力不同的UE(例如TA不同的一组UE)，则网络设备在向该组中的各UE配置参考时延时，需要考虑该组UE中TA的值最大的UE也有足够的取消时间。
下面对TA进行简要的介绍。在小区内，由于不同UE所处的位置可能不同，距离基站的距离也可能各不相同。因此，基站与UE之间的信号会经历不同的传输时延。为了保证基站在接收来自不同UE的上行信号时保持定时是对齐的，UE需要在发送上行信号时，基于下行定时增加一个偏移，该偏移值即为TA值，通常由基站来配置。基站通过TA可以控制不同UE的上行传输提前量。对于距离基站较近的UE，传输时延较小，可配置较小的TA；对于距离基站较远的UE，所经历的传输时延较大，需要配置较大的TA。
在第二种方式中，可以将从UL CI的接收时刻开始经过参考时延之后的第一个时隙的边界或第一个符号，确定为上述第一起始时刻。
具体来说，在给定的SCS下，可以将从UL CI的接收时刻开始经过参考时延之后的第一个时隙的边界，确定为上述第一起始时刻。
例如，假设RRC配置的参考时延为1个时隙，参考时间区域的总长度为X个时隙，UE在时隙n接收到UL CI，则UE可以将时隙n+1结束的时刻作为第一起始时刻，相应的，将时隙n+1之后开始的X个时隙确定为参考时间区域。
又如，假设RRC配置的参考时延为7个符号，参考时间区域的总长度为X个时隙，UE在时隙n的符号i(i<7，i＝0～13)接收到UL CI，则UE可以将时隙n+1结束的时刻作为第一起始时刻，相应的，将时隙n+1之后开始的X个时隙确定为参考时间区域。
再如，假设RRC配置的参考时延为14个符号，参考时间区域的总长度为X个时隙，UE在时隙n的符号i(i＝0～13)接收到UL CI，则UE可以将时隙n+2结束的时刻作为第一起始时刻，相应的，将时隙n+2之后开始的X个时隙确定为参考时间区域。
或者，在给定的SCS下，第一起始时刻可以是从UL CI的接收时刻开始经过参考时延之后的第一个符号。
例如，假设RRC配置的参考时延为7个符号，参考时间区域的总长度为X个时隙，UE在时隙n的符号i(i<7，i＝0～13)接收到UL CI，则UE可以将时隙n的符号i再加7个符号之后的第一个符号确定为第一起始时刻，相应的，将时隙n的符号i再加7个符号之后开始的X个时隙确定为参考时间区域。
再如，假设RRC配置的参考时延为14个符号，参考时间区域的总长度为X个时隙，UE在时隙n的符号i(i＝0～13)接收到UL CI，则UE可以将时隙n+1的符号i之后的第一个符号确定为第一起始时刻，相应的，将时隙n+1的符号i之后开始的X个时隙确定为参考时间区域。
又如，假设RRC配置的参考时延为14个符号，参考时间区域的总长度为Y个符号，UE在时隙n的符号i(i＝0～13)接收到UL CI，则UE可以将时隙n+1的符号i之后的第一个符号确定为第一起始时刻，相应的，将时隙n+1的符号i之后开始的Y个符号确定为参考时间区域。
对于第三种方式而言，UE可以基于设定的最小取消时间(minimum cancellation time)确定上述预设时间间隔，也即第一预设值可以为最小取消时间。最小取消时间，可以理解为是UE能够取消上行传输所需的最短处理时间，它的大小与UE的能力和SCS有关，一般而言，UE的能力越强，最小取消时间越短，反之，最小取消时间越长。最小取消时间的单位为时隙或符号。
最小取消时间既可以是协议预定的，也可以是网络设备给UE配置的。一般情况下，最小取消时间中不包括TA。
当第一预设值为最小取消时间时，第三种方式具体可以包括：根据上行定时提前的值和所述最小取消时间，确定所述预设时间间隔。更为具体的， 可以将上行定时提前的值和所述最小取消时间的和(minimum cancellation time+TA)，确定为上述预设时间间隔。并且，可以将从UL CI的接收时刻开始经过最小取消时间+TA之后的第一个时隙的边界或第一个符号，确定为上述第一起始时刻。
在上述确定预设时间间隔的第三种方式中，TA值可以是UE专有的TA值(UE-specific TA)；TA值也可以是UE所在用户组(UE group)中所有UE的TA值中的最大值，且该最大值可以通过RRC的配置得到；TA值还可以是一个设定的参考TA(reference TA)值，例如可配置的最大的TA值。
具体来说，在给定的SCS下，可以将从UL CI的接收时刻开始经过最小取消时间+TA之后的第一个时隙的边界，确定为上述第一起始时刻。
例如，假设最小取消时间等于10个符号，参考时间区域的总长度为X个时隙，TA为4个符号，最小取消时间+TA＝14个符号，UE在时隙n的符号i＝7(i＝7～13)接收到UL CI，则UE可以将时隙n+2结束的时刻作为第一起始时刻，相应的，将时隙n+2之后开始的X个时隙确定为参考时间区域。
或者，在给定的SCS下，可以将从UL CI的接收时刻开始经过最小取消时间+TA之后的第一个符号，确定为上述第一起始时刻。
例如，假设最小取消时间等于10个符号，参考时间区域的总长度为X个时隙，TA为4个符号，最小取消时间+TA＝14个符号，UE在时隙n的符号i(i＝0～13)接收到UL CI，则UE可以将时隙n+m的符号j之后的第一个符号作为第一起始时刻，相应的，将时隙n+m的符号j之后开始的X个时隙确定为参考时间区域。其中，m＝floor((i+最小取消时间+TA)/14)，j＝mod(i+最小取消时间+TA，14)，函数floor()表示向下取整，函数mod()表示取余数。
或者，在给定的SCS下，当TA具体为group-specific TA(UE组专属TA)时，可以将从UL CI的接收时刻开始经过最小取消时间+UE组专属TA之后的第一个时隙的边界或第一个符号，确定为上述第一起始时刻。
具体而言，当多个UE配置了检测同一个UL CI时，TA可以为网络设备配置的UE组专属TA，且该UE组专属TA能够使同一个UE组内所有的UE具备足够的取消时间(cancellation time)。例如，UE组专属TA可以为该UE组内所有UE的TA值中的最大值。
或者，在给定的SCS下，当TA具体为参考TA(reference TA)时，可以将从UL CI的接收时刻开始经过最小取消时间+参考TA之后的第一个时隙的边界或第一个符号，确定为上述第一起始时刻。
具体而言，当多个UE配置了检测同一个UL CI时，TA可以为网络设备配置的参考TA，且该参考TA能够使同一个UE组内所有的UE具备足够的取消时间(cancellation time)。例如，参考TA可以为可配置的TA值中的最大值。
步骤102、基于所述第一起始时刻，确定取消上行传输的目标时间区域。
目标时间区域，可以理解为是欲取消上行传输的时间区域，目标时间区域通常位于步骤101中所述的参考时间区域之内。
可选地，在步骤102中确定出目标时间区域之后，本公开实施例提供的一种取消上行传输的方法还可以包括：暂停或取消在所述目标时间区域上的上行传输。当然，在实际应用中，如果UL CI的接收时刻与目标时间区域之间没有足够的取消时间(cancellation time)，则UE可以忽略该UL CI，一般情况下，取消时间＝最小取消时间+TA，TA为UE当前由网络指示或配置的TA。
下面对步骤102的可能的几种具体实施方式进行说明。
在第一种实施方式中，在步骤102之前，本公开实施例提供的一种取消上行传输的方法还可以包括：确定所述参考时间区域的总长度。相应的，上述步骤102具体可以包括：基于所述总长度和所述第一起始时刻，确定所述目标时间区域。
示例性地，参考时间区域的总长度可以基于下列方式中的一种来确定：
基于用于配置所述总长度的高层信令(例如RRC)，确定所述总长度。总长度L的单位可以是时隙或符号，L的取值与上行(Uplink，UL)带宽部分(bandwidth part，BWP)的数值配置(numerology)有关，如果总长度L的单位为时隙，则L的取值可以是1、2、4、5等，如果总长度L的单位为符号，L的取值可以为7、14、28符号等。
或者，基于所述上行传输取消指令的检测周期(monitoring periodicity)确定所述总长度。如果UL CI的检测周期为X个时隙或Y个符号，那么参考 时间区域的总长度也可以为X个时隙或Y个符号。UL CI的检测周期的取值可以是7个符号、1个时隙、2个时隙，等等。
或者，基于第二预设值确定所述总长度，也即参考时间区域的长度可以是固定值，例如1个时隙。
更为具体的，在步骤102中，可以将从所述第一起始时刻开始经过所述总长度的时间区域，确定为所述目标时间区域，也即将所述参考时间区域确定为所述目标时间区域。
例如，假设已知参考时间区域的起始时刻(第一起始时刻)和总长度，且UL CI中不包括取消上行传输的目标起始时刻信息和目标长度信息，也即UL CI不指示参考时间区域内的cancelled slot/symbol(s)，则UE可以将参考时间区域确定为取消上行传输的目标时间区域，并取消目标时间区域上的上行传输。
具体如图2所示，假设UE根据UL CI的指示确定出K3＝1个时隙，参考时间区域的总长度为1个时隙，UE在时隙n接收到UL CI(图2中的12)，则UE可以确定出第一起始时刻t1为从时隙n开始经过K3之后的第一个时隙的起始时刻(边界)，参考时间区域为时隙n+1(图2中的21)，UE可以取消在参考时间区域21(时隙n+1)上的上行eMBB业务传输。
在具体实现时，网络设备可以通过RRC信令预先在UE中配置(configured)一个如下表1所示的K3集合，UL CI指示该表中的一个编号(index)，UE通过编号查询表1就可以确定出具体的K3值。需要说明的是，网络设备通过UL CI指示K3时，要考虑UE的能力。

需要说明的是在本说明书附图中，K2 eMBB表示eMBB业务传输占用的时域资源，附图标记1表示下行(Downlink，DL)，附图标记2表示上行(Uplink，UL)，附图标记11表示用于调度eMBB传输上行调度信令(UL grant for  eMBB)，附图标记12表示UL CI，附图标记21表示参考时间区域，附图标记22所指的方框中的填充图样表示eMBB业务传输，附图标记23所指的方框中的填充图样表示取消上行传输的eMBB业务，附图标记24所指的方框中的填充图样表示URLLC业务传输，附图标记25表示一个符号，为节约篇幅，下文直接引用相应的附图标记，不再重复描述其含义。
再如图3所示，假设UE根据UL CI的指示确定出K3＝14个符号，参考时间区域的总长度为Y个符号，UE在时隙n的符号i(i＝0～13)接收到UL CI(图3中的12)，则UE可以确定出第一起始时刻t1为从时隙n开始经过K3之后的第一个符号，参考时间区域为时隙n+1的符号i开始的Y个符号(图3中的21)，UE可以取消在参考时间区域21上的上行eMBB业务传输(图3中填充图样为附图标记23所指的部分)。
在具体实现时，网络设备可以通过RRC信令预先在UE中配置(configured)一个如下表2所示的K3集合，UL CI指示该表中的一个编号(index)，UE通过编号查询表2就可以确定出具体的K3值。需要说明的是，网络设备通过UL CI指示K3时，要考虑UE的能力。

在第二种实施方式中，在步骤102之前，本公开实施例提供的一种取消上行传输的方法还可以包括：确定所述参考时间区域的总长度。相应的，上述步骤102具体可以包括：基于所述总长度和所述第一起始时刻，确定所述目标时间区域。并且，UL CI中包括用于指示取消上行传输的时域资源的目标起始时刻信息，则本公开实施例提供的一种取消上行传输的方法还可以包括：基于所述第一起始时刻和所述目标起始时刻信息，确定取消上行传输的第二起始时刻。第二起始时刻是相对于第一起始时刻而言的，通常情况下，第二起始时刻晚于或等于上述第一起始时刻。
相应的，上述基于所述总长度和所述第一起始时刻，确定所述目标时间 区域，具体可以包括：基于所述总长度和所述第一起始时刻确定所述参考时间区域的结束时刻；将从所述第二起始时刻开始至所述结束时刻之间的时间区域，确定为所述目标时间区域。
例如，假设已知参考时间区域的起始时刻(第一起始时刻)和总长度，UL CI对取消上行传输的目标起始时刻信息(第二起始时刻)做出进一步地指示，也即UL CI指示参考时间区域内的cancelled slot/symbol(s)，则UE可以从第二起始时刻开始至参考时间区域的结束时刻之间的时间区域确定为目标时间区域，并取消目标时间区域上的上行传输。
具体而言，UL CI可以用一个比特区域(bit-field)指示第二起始时刻(starting symbol)，该比特区域的大小(Bit-field size)可以为：Bit-field size＝ceil(log2(N symbol*X/N bundle_size))，其中，公式ceil()表示返回大于或等于括号内数值的最小整数(上取整)，X表示参考时间区域的总时隙数，N symbol表示一个时隙内的符号数；N bundle_size表示子区域的大小(或者符号组合的大小(symbol bundle size))，也可以称为子区域的符号数，N bundle_size可以理解为是子区域的粒度，下文会对子区域(或者符号组合)进行单独说明，此处暂不赘述。
如图4所示，假设UE根据UL CI的指示确定出K3＝1个时隙，参考时间区域的总长度为1个时隙(X＝1)，UE在时隙n接收到UL CI(图4中的12)，则UE可以确定出第一起始时刻t1为从时隙n开始经过K3之后的第一个时隙的边界，参考时间区域为时隙n+1(图4中的21)。并且，假设UL CI进一步指示第二起始时刻t2为第一起始时刻t1之后的第5个符号(starting symbol为5)，UL CI中用于指示t1的比特区域的大小为：Bit-field size＝ceil(log2(N symbol))，子区域的粒度为1个符号。则UE可以将时隙n+1中的符号5至符号13之间的时间区域确定为目标时间区域，并取消在时隙n+1中的符号5至符号13之间的时间区域上的上行eMBB业务传输(图4中填充图样为附图标记23所指的部分)。
再如图5所示，假设UE根据UL CI的指示确定出K3＝1个时隙，参考时间区域的总长度为1个时隙(X＝1)，UE在时隙n接收到UL CI(图5中的12)，则UE可以确定出第一起始时刻t1为从时隙n开始经过K3之后的第一 个时隙的边界，参考时间区域为时隙n+1(图5中的21)。并且，假设UL CI进一步指示第二起始时刻t2为第一起始时刻t1之后的第4个符号(starting symbol为4)，UL CI中用于指示t1的比特区域的大小为：Bit-field size＝ceil(log2(N symbol/2))，子区域的粒度为2个符号。则UE可以将时隙n+1中的符号4至符号13之间的时间区域确定为目标时间区域，并取消在时隙n+1中的符号4至符号13之间的时间区域上的上行eMBB业务传输(图5中填充图样为23的部分)。
再如图6所示，假设UE根据最小取消时间(t min＝10个符号)和TA(2个符号)确定出预设时间间隔为12个符号，参考时间区域的总长度为1个时隙(X＝1)，UE在时隙n的第1个符号接收到UL CI(图6中的12)，则UE可以确定出第一起始时刻t1为从时隙n的第1个符号开始经过12个符号之后的第一个时隙的边界，参考时间区域为时隙n+1(图6中的21)。并且，假设UL CI进一步指示第二起始时刻t2为第一起始时刻t1之后的第4个符号(starting symbol为4)，UL CI中用于指示t1的比特区域的大小为：Bit-field size＝ceil(log2(N symbol/2))，子区域的粒度为2个符号。则UE可以将时隙n+1中的符号4至符号13之间的时间区域确定为目标时间区域，并取消在时隙n+1中的符号4至符号13之间的时间区域上的上行eMBB业务传输(图6中填充图样为附图标记23所指的部分)。
再如图7所示，假设UE根据最小取消时间(t min＝10个符号)和TA(2个符号)确定出预设时间间隔为12个符号，参考时间区域的总长度为Y个符号，UE在时隙n的第1个符号接收到UL CI(图7中的12)，则UE可以确定出第一起始时刻t1为从时隙n的第1个符号开始经过12个符号之后的第1个符号，参考时间区域为第一起始时刻t1开始的Y个符号(图7中的21)。并且，假设UL CI进一步指示第二起始时刻t2为第一起始时刻t1之后的第5个符号(starting symbol为5)，UL CI中用于指示t1的比特区域的大小为：Bit-field size＝ceil(log2(Y/2))，子区域的粒度为2个符号。则UE可以将第一起始时刻t1之后的第5个符号至第一起始时刻t1之后的第Y个符号之间的时间区域确定为目标时间区域，并取消在目标时间区域上的上行eMBB业务传输(图7中填充图样为附图标记23所指的部分)。
在第三种实施方式中，在步骤102之前，本公开实施例提供的一种取消上行传输的方法还可以包括：确定所述参考时间区域的总长度。相应的，上述步骤102具体可以包括：基于所述总长度和所述第一起始时刻，确定所述目标时间区域。并且，UL CI中包括用于指示取消上行传输的时域资源的目标起始时刻信息和目标长度信息(cancelled slot/symbol)，则本公开实施例提供的一种取消上行传输的方法还可以包括：基于所述第一起始时刻和所述目标起始时刻信息，确定取消上行传输的第二起始时刻；基于所述目标长度信息，确定取消上行传输的目标长度。第二起始时刻是相对于第一起始时刻而言的，通常情况下，第二起始时刻晚于或等于上述第一起始时刻。
相应的，上述步骤102具体可以包括：将从所述第二起始时刻开始经过所述目标长度的时间区域，确定为所述目标时间区域，并暂停或取消在目标时间区域上的上行eMBB业务传输。通常情况下，依照该方式确定的目标时间区域位于上述参考时间区域内。
具体而言，UL CI可以用一个比特区域(bit-field)指示第二起始时刻和目标长度(start and length indicator，SLIV)，目标长度不超过参考区域的总长度，该比特区域的大小(Bit-field size)可以为：Bit-field size＝ceil(log2(N symbol*X/N bundle_size)*(N symbol*X/N bundle_size+1)/2)，其中，X表示参考时间区域的总时隙数，N symbol表示一个时隙内的符号数；N bundle_size表示子区域的大小(或者符号组合的大小(symbol bundle size))，也可以称为子区域的符号数，N bundle_size可以理解为是子区域的粒度，下文会对子区域(或者符号组合)进行单独说明，此处暂不赘述。
如图8所示，假设UE根据UL CI的指示确定出K3＝1个时隙，参考时间区域的总长度为1个时隙(X＝1)，UE在时隙n接收到UL CI(图8中的12)，UE将从时隙n开始经过K3之后的第一个时隙的边界确定为第一起始时刻t1，将时隙n+1确定为参考时间区域(图8中的21)。并且，假设UL CI进一步指示第二起始时刻t2为第一起始时刻t1之后的第5个符号(starting symbol为5)，目标长度T为3个符号，UL CI中用于指示t1和T的比特区域的大小为：Bit-field＝ceil(log2(N symbol*(N symbol+1)/2))，子区域的粒度为1个符号。则UE可以将时隙n+1中的符号5至符号8之间的时间区域确定为目标时间区域， 并取消在时隙n+1中的符号5至符号8之间的时间区域上的上行eMBB业务传输(图8中填充图样为附图标记23所指的部分)。
再如图9所示，假设UE根据UL CI的指示确定出K3＝1个时隙，参考时间区域的总长度为1个时隙(X＝1)，UE在时隙n接收到UL CI(图9中的12)，UE将从时隙n开始经过K3之后的第一个时隙的边界确定为第一起始时刻t1，将时隙n+1确定为参考时间区域(图9中的21)。并且，假设UL CI进一步指示第二起始时刻t2为第一起始时刻t1之后的第4个符号(starting symbol为4)，目标长度T为5个符号，UL CI中用于指示t1和T的比特区域的大小为：Bit-field＝ceil(log2(N symbol/2*(N symbol+1)/2))，子区域的粒度为2个符号。则UE可以将时隙n+1中的符号4至符号9之间的时间区域确定为目标时间区域，并取消在时隙n+1中的符号4至符号9之间的时间区域上的上行eMBB业务传输(图9中填充图样为附图标记23所指的部分)。
再如图10所示，假设UE根据最小取消时间(t min＝10个符号)和TA(TA＝2个符号)确定出预设时间间隔为12个符号，参考时间区域的总长度为1个时隙(X＝1)，UE在时隙n的第1个符号接收到UL CI(图10中的12)，则UE可以确定出第一起始时刻t1为从时隙n的第1个符号开始经过12个符号之后的第一个时隙的边界，参考时间区域为时隙n+1(图10中的21)。并且，假设UL CI进一步指示第二起始时刻t2为第一起始时刻t1之后的第4个符号(starting symbol为4)，目标长度T为5个符号，UL CI中用于指示t1和T的比特区域的大小为：Bit-field＝ceil(log2(N symbol/2*(N symbol+1)/2))，子区域的粒度为2个符号。则UE可以将时隙n+1中的符号4至符号9之间的时间区域确定为目标时间区域，并取消在时隙n+1中的符号4至符号9之间的时间区域上的上行eMBB业务传输(图10中填充图样为附图标记23所指的部分)。
再如图11所示，假设UE根据最小取消时间(t min＝10个符号)和TA(TA＝2个符号)确定出预设时间间隔为12个符号，参考时间区域的总长度为Y个符号，UE在时隙n的第1个符号接收到UL CI(图11中的12)，则UE可以确定出第一起始时刻t1为从时隙n的第1个符号开始经过12个符号之后的第一个符号，参考时间区域为第一起始时刻t1开始的Y个符号(图11中的 21)。并且，假设UL CI进一步指示第二起始时刻t2为第一起始时刻t1之后的第5个符号(starting symbol为4)，目标长度T为6(duration＝6)个符号，UL CI中用于指示t1和T的比特区域的大小为：Bit-field＝ceil(log2(Y/2*(Y+1)/2))，子区域的粒度为2个符号，公式ceil()表示返回大于或等于括号内数值的最小整数。则UE可以将第一起始时刻t1之后的第5个符号至第一起始时刻t1之后的第11个符号之间的时间区域确定为目标时间区域，并取消该目标时间区域上的上行eMBB业务传输(图11中填充图样为附图标记23所指的部分)。
本公开实施例提供的一种取消上行传输的方法，可以在接收到上行传输取消指令时，确定出参考时间区域的起始时刻，并根据参考时间区域的起始时刻确定出目标时间区域，进而暂停或取消在目标时间区域上的上行传输。因此，可以使终端设备明确需要取消的上行传输的具体时域资源，提高了系统的资源调度效率。
在本公开的又一实施例中，取消上行传输资源的方法可以包括：在接收到上行传输取消指令(UL CI)时，根据所述上行传输取消指令中指示的时延(offset)，确定取消上行传输的时隙；根据所述上行传输取消指令中指示的要取消上行传输的起始符号，以及所述取消上行传输的时隙，确定取消上行传输的目标时间区域。也即，不设定参考时间区域(或者说隐含设定参考时间区域)，UL CI中指示时延和实际要取消的时隙或符号(cancelled slot/symbol(s))。
其中，根据所述上行传输取消指令中指示的时延(offset)，确定取消上行传输的时隙，包括：将从所述上行传输取消指令的接收时刻开始经过所述时延之后的第一个符号所在的时隙，确定为取消上行传输的时隙。
具体而言，可以预先通过RRC在UE中配置一个K3时延的集合(见上文中的表1)，UL CI指示具体的K3值，UE根据UL CI的接收时刻和K3确定要取消的符号所在的时隙，然后从所指示的起始符号开始，取消该时隙上的上行传输。
具体如图12所示，假设UE在时隙n的符号i接收到UL CI(图12中的12)，且UL CI指示了K3的具体值，UE根据UL CI的接收时刻和K3确定出 取消上行传输的时隙为时隙n+1。并且，假设UL CI进一步指示要取消上行传输的起始符号为4(starting symbol为4)，则可以将时隙n+1中的符号4至时隙n+1的最后一个符号之间的时间区域确定为目标时间区域，并取消在时隙n+1中的符号4至时隙n+1的最后一个之间的时间区域上的上行eMBB业务传输(图12中填充图样为附图标记23所指的部分)。
再比如，假设UL CI中用一个比特区域(Bit-field)指示相对于UL CI的接收时刻的要取消上行传输的符号(cancelled symbol(s))中的起始符号(starting symbol)，且网络设备预先通过RRC配置的比特区域的大小为：Bit-field size＝ceil(log2(max_total_symbol_num/N bundle_size))，其中，N bundle_size表示符号组合的大小(symbol bundle size)，由RRC配置UL CI能指示的最远的起始符号，该配置也决定了比特区域的大小；max_total_symbol_num，表示RRC隐式配置或默认的参考时间区域的总符号数。UE接收到UL CI之后，根据比特区域中的指示确定要取消上行传输的起始符号所在的时隙，然后从所示指示的起始符号开始，取消该时隙上的上行传输。
又比如，假设UL CI中用一个比特区域(Bit-field)指示相对于UL CI的接收时刻的要取消上行传输的符号(cancelled symbol(s))中的起始符号(starting symbol)和目标长度(duration)，也即UL CI指示SLIV，且网络设备预先通过RRC配置的比特区域的大小为：Bit-field size＝ceil(log2(max_total_symbol_num/N bundle_size)*(max_total_symbol_num/N bundle_size)+1)/2)，其中，N bundle_size表示符号组合的大小(symbol bundle size)，由RRC配置UL CI能指示的最远的起始符号，该配置也决定了比特区域的大小。UE接收到UL CI之后，根据UL CI的比特区域中所指示的SLIV确定要取消上行传输的起始符号和目标长度，然后从所示指示的起始符号开始，取消在目标长度的时域资源上的上行传输。
下面对上文中述及的子区域(或者符号组合)进行说明。
可选地，本公开任一实施例提供的一种取消上相传输的方法还可以包括：基于用于划分所述参考时间区域的高层信令(例如RRC)，将所述参考时间区域划分为预设长度的多个子区域，或者将一个时隙划分为预设长度的多个子区域，以减小UL CI中的比特区域的大小，从而节省传输资源。
其中，所述预设长度大于或等于一个时间符号；所述目标起始时刻信息用于指示取消上行传输的时域资源中包括的子区域中的起始子区域，所述目标长度信息用于指示取消上行传输的时域资源中包括的子区域的数量。
举例来说，假设一个时隙有14个符号，当子区域的大小等于1个符号时，UL CI需要4个比特(能指示0～15)才能实现对时隙中所有符号的指示；当子区域的大小等于2个符号时(2个符号的组合)，该时隙包括7个子区域，UL CI需要3个比特(能指示0～7)就能实现对该时隙中所有子区域的指示，因此，对时隙中或参考时间区域中的符号进行组合，可以减少UL CI中的比特区域的大小，能够节省UL CI占用的传输资源。
在具体实现时，子区域的大小(或符号组合的大小)可以由网络设备通过RRC进行配置。
可选地，如图13所示，本公开任一实施例提供的一种取消上相传输的方法还可以包括：
步骤103、若所述上行传输取消指令中包括频域指示信息，根据所述频域指示信息，确定取消上行传输的目标频域资源；
上述UL CI中可以包括有频域指示信息，当然也可以不包括(频域指示信息)，终端设备在接收UL CI之前，通常是可以确定(如高层信令配置或协议规定的)UL CI中是否包括有频域指示信息。
上述频域指示信息，可以是用来指示待暂停或待取消上行传输的目标频域资源。该处提到的目标频域资源，可以为一确定的参考频域区域(Reference Frequency region)；也可以是上述参考频域区域中的一个或多个频带子集。
上述参考频域区域，可以是根据来自于网络设备的高层信令确定得到；或者是在协议中约定。在一种具体的实施方式中，所述参考频域区域默认为终端设备当前激活的上行BWP；在另一种具体的实施方式中，所述参考频域区域为所述网络设备通过高层信令配置的频域带宽，该处配置的频域带宽，可以是上述当前激活的上行BWP，也可以是当前激活的上行BWP中的部分带宽。
步骤104、根据所述目标时间区域和所述目标频域资源，确定取消上行传输的目标时频资源。
当然，在确定出目标频域资源之后，终端设备还可以暂停或取消在所述目标时频资源上的上行传输，从而实现了URLLC业务的低时延和高可靠性要求。
上述提到，UL CI中的频域指示信息可以用来指示参考频域区域的一个或多个频带子集，即目标频域资源，其中，这些频带子集可以是对参考频域区域进行分段得到，例如，参考频域区域的带宽为400MHz-500MHz，被分为10个相等的频带子集，第一个频带子集为400MHz-410MHz；第二个频带子集为410MHz-420MHz；……；第十个频带子集为490MHz-500MHz。
每个频带子集的大小、或者是频带子集的数量，均可以是根据自于网络设备的高层信令确定。每个频带子集的大小、或者是频带子集的数量，反映了频域资源指示的粒度。
对于UL CI中的频域指示信息指示一个或多个频带子集的方式，可以有如下几种实施方式：
实施方式一，采用位图指示的方式指示频带子集。
例如，参考频域区域被分割为M(M为大于1的正整数)个频带子集，这样，UL CI中的指示信息可以具体为M比特的位图，根据上述位图来指示出一个或多个频带子集，即目标频域资源。当M＝1时，UL CI中可以不包括频域指示信息(后续介绍)。
该处的M比特的位图可以用来指示参考频域区域的单个频带子集；或，可以用来指示参考频域区域的多个连续的频带子集；或，可以用来指示参考频域区域的多个不连续的频带子集。
利用位图指示的方式，配置方便，指示方式灵活，可以按照灵活地指示一个或多个频带子集。
实施方式二，采用单个索引指示的方式指示频带子集，例如，参考频域区域被分割为M(M为大于1的正整数)个频带子集，每一个频带子集均配置有索引，这样，UL CI中的指示信息可以具体用于指示频带子集的索引。当M＝1时，UL CI中可以不包括频域指示信息(后续介绍)。
该实施方式可以用来指示所述参考频域区域的单个频带子集，对于每一个频带子集，UL CI中可以包括有ceil(log 2M)比特的频域指示信息，公式ceil() 表示返回大于或等于括号内数值的最小整数。
实施方式三，采用索引和连续的频带子集的数量的方式指示频带子集，例如，参考频域区域被分割为M(M为大于1的正整数)个频带子集，每一个频带子集均配置有索引，这样，UL CI中的频域指示信息可以具体用于指示多个连续的频带子集中的起始频带子集的索引和所述多个连续的频带子集的数量，此时，目标频域资源为上述多个连续的频带子集。
该实施方式中，UL CI中可以包括有
Figure PCTCN2019077649-appb-000001
比特的频域指示信息，分别用来指示多个连续的频带子集中的起始频带子集的索引和所述多个连续的频带子集的数量。
采用实施方式三的指示方法，因频域指示信息的数据量较小，能够节约信令开销。
例如，如图14所示，假设UE在时隙n接收到UL CI(图14中的12)，参考时间区域的总长度为2个时隙，且UL CI指示了K3＝1个时隙，UE将从时隙n开始经过K3之后的第一个时隙的边界确定为第一起始时刻t1，将时隙n+1和时隙n+2确定为参考时间区域，以及，UL CI指示的子区域的粒度为2个符号。并且，参考频域资源(Reference frequency region)为UL BWP，参考频域资源分为4个频带子集，UL CI用2比特指示具体要取消的频带子集，作为目标频域资源。以及，UL CI进一步指示要取消上行传输的起始符号为5(starting symbol为5)，UL指示要取消上行传输的目标频域资源为第一个频带子集；则UE确定可以取消的频域资源为，在时隙n+1的第5个符号至时隙n+2的第14个符号上，与目标频域资源重叠的频域资源(图14中填充图样为附图标记23所指的部分)。在图14中t表示时间，f表示频率。
通过本公开实施例提供的取消上行传输的方法，终端设备在接收到上行传输取消指令时，可确定出取消上行传输的目标时频资源，提高了系统的资源调度效率。
可选地，如图15所示，本公开任一实施例提供的一种取消上相传输的方法还可以包括：
步骤105、若所述上行传输取消指令中不包括所述频域指示信息，将参考频域区域确定为取消上行传输的目标频域资源；
步骤106、根据所述目标时间区域和所述目标频域资源，确定取消上行传输的目标时频资源；
其中，所述参考频域区域为网络设备通过高层信令配置的频域带宽，或，所述参考频域区域为终端设备基于协议确定的频域带宽。
具体地，该处的参考频域区域可以是当前激活的上行BWP；也可以是当前激活的上行BWP中的部分带宽。
终端设备在接收上行传输取消指令时，可以直接将参考频域区域确定为取消上行传输的目标频域资源。
将参考频域区域确定为取消上行传输的目标频域资源之后，还可以暂停或取消在所述目标频域资源上的上行传输。
同样的，通过本公开实施例提供的取消上行传输的方法，终端设备在接收到上行传输取消指令时，可确定出取消上行传输的目标时频资源，提高了系统的资源调度效率。
