具体实施方式
下文中将结合附图对本申请的实施例进行详细说明。
在附图的流程图示出的步骤可以在诸如一组计算机可执行指令的计算机系统中执行。并且，虽然在流程图中示出了逻辑顺序，但是在某些情况下，可以以不同于此处的顺序执行所示出或描述的步骤。
新制式(New RAT，NR)为保证覆盖引入时隙聚合(slot aggregation)传输，即用户设备(User Equipment，UE)在多个时隙中相同的时域符号位置和频域资源块(Resource Block，RB)位置重复传输传输块(Transmission Block，TB)， 目前可聚合的时隙长度为1或2或4或8。基站通过配置无线资源控制(Radio Resource Control，RRC)消息中的下行聚合因子(aggregation Factor DL)表示下行链路是否进行聚合传输，通过RRC消息中的上行聚合因子(aggregation Factor UL)表示上行链路是否进行时隙聚合传输，如果配置的聚合因子大于1，则表明用户设备(User Equipment，UE)需要进行时隙聚合传输，基站会在时隙聚合传输的第一个时隙(slot)由调度(grant)消息调度，在后续的可用时隙中相同的时域符号位置和相同的频域RB位置重复传输传输块(Transmission Block，TB)。
另外，基站会通过高层信令为UE配置一组部分带宽(Bandwidth Part，BWP)，至多4个下行链路(DownLink，DL)BWP和4个上行链路(UpLink，UL)BWP，不同BWP可独立配置子载波间隔、带宽和频域位置等，目前标准中BWP切换可分为静态BWP切换、动态BWP切换和基于时间(time)的BWP切换，例如有更大的数据包到达需要变到更大的带宽上发送，这时就需要切换到更大带宽的BWP，5G基站(gNB)可通过下行控制信息(Downlink Control Information，DCI)中的BWP指示域动态切换BWP，UE检测该BWP指示域与之前的BWP指示域信息不同即确定需要完成BWP的切换。另外，目前标准定义对于时分双工(Time Division Duplexing，TDD)系统，需要保证DL BWP与UL BWP中心载频相同，意味着对于TDD系统如果DL BWP发生切换，则UL BWP也需要发生切换。
如图1所示，图中，U的方块表示上行时隙，D的方块表示下行时隙，假设聚合的时隙长度为4，并且，聚合的四个上行时隙中间穿插有聚合的四个下行时隙中的两个下行时隙，当UE在进行上行时隙聚合传输过程中发生BWP切换时，如果UE继续按照原UL BWP进行时隙聚合传输，则有可能会导致传输失败。
参见图2，本申请一个实施例提出了一种传输方法，包括：步骤200。
在步骤200中，当在进行时隙聚合传输过程中满足第一预设条件时，停止在聚合的时隙中尚未传输的时隙中传输数据。
在本申请的实施例中，时隙聚合传输中的第一个时隙的传输通过第一下行控制信息指示或者无线资源控制消息配置。
其中，第一DCI用于基于调度(grant based)传输，RRC消息用于免调度(grant free)传输。
例如，第一DCI动态指示时隙聚合传输中的第一个时隙的传输使用的频域资源、时域符号、调制编码方式、码流数、传输层数目、以及冗余版本(Redundancy Version，RV)号等。
又如，RRC半静态配置时隙聚合传输中的第一个时隙的传输使用的频域资源、使用时域符号、使用的调制编码方式、码流数、传输层数目、以及RV号等。
在本申请的实施例中，数据承载在以下任一种：
物理上行控制信道(Physical Uplink Control Channel，PUCCH)；
物理上行共享信道(Physical Uplink Shared Channel，PUSCH)；
物理下行共享信道(Physical Downlink Shared Channel，PDSCH)；
物理下行控制信道(Physical Downlink Control Channel，PDCCH)。
本申请的实施例中，第一预设条件包括以下至少一种：
发生部分带宽切换；
第三下行控制信息中部分带宽指示域与所述第一下行控制信息中部分带宽指示域不同；
第三下行控制信息中部分带宽指示域与第四下行控制信息中部分带宽指示域不同；
第三下行控制信息中至少一个新增比特域或除部分带宽指示域以外的其他比特域满足第二预设条件；
切换后的部分带宽的子载波间隔与切换前的部分带宽的子载波间隔不同；
切换后的部分带宽的大小与切换前的部分带宽的大小不同；
其中，所述第三下行控制信息和所述第四下行控制信息用于指示非聚合传输的时隙的数据传输。
其中，第三下行控制信息中至少一个新增比特域或除部分带宽指示域以外的其他比特域满足第二预设条件包括以下至少之一：
新增比特域或除部分带宽指示域以外的其他比特域指示停止在聚合的时隙中尚未传输的时隙中传输数据；
新增比特域或除部分带宽指示域以外的其他比特域的预设状态指示停止在聚合的时隙中尚未传输的时隙中传输数据。
其中，可以通过新增比特域或除部分带宽指示域以外的其他比特域显式或隐式指示停止在聚合的时隙中尚未传输的时隙中传输数据。
例如，如果发生BWP切换就停止在后续的时隙聚合中传输数据；
或者，如果发生BWP切换，且切换后的BWP的子载波间隔与切换前的子载波间隔不同就停止在后续的时隙聚合中传输数据；
或者，如果发生BWP切换，且切换后的BWP的大小与切换前的BWP的大小不同就停止在后续的时隙聚合中传输数据；
或者，如果发生BWP切换，且切换后的BWP的大小与切换前的BWP的大小不同，且切换后的BWP的子载波间隔与切换前的BWP的子载波间隔不同就停止在后续的时隙聚合中传输数据；
或者，通过新增一个比特域显式指示停止在后续的时隙聚合中传输数据；
或者，通过BWP指示域比特域来指示BWP是否发生切换，当BWP指示域指示BWP发生切换时隐式指示停止在后续的时隙聚合中传输数据；
或者，通过频域资源分配域的预设状态停止在后续的时隙聚合中传输数据，例如，将频域资源分配域中的比特全部配置为1或者全部配置为0。
在本申请的实施例中，UE可以根据gNB发送的第三DCI中的BWP指示域与第一DCI中的BWP指示域是否相同来判断BWP是否发生切换。在一实施例中，当第三DCI中的BWP指示域与第一DCI中的BWP指示域不同时，确定BWP发生切换；当第三DCI中的BWP指示域与第一DCI中的BWP指示域相同时，确定BWP未发生切换。
例如，如图3所示为4时隙上行聚合传输的示意图，该上行聚合传输的第一个时隙(slot)是通过第一个U时隙(即上行时隙)前下发的DCI(UL grant)即所述第一DCI指示传输数据，第一DCI中的BWP指示域例如为00，表示使用BWP ID为1，在图中第一个D时隙(即下行时隙)发生BWP切换，UE在该时隙接收到DCI(DL grant)即所述第三DCI，第三DCI中的BWP指示域例如为01，表示使用BWP ID为2，则表明BWP发生切换，从BWP1变为BWP2，对于TDD帧结构，下行BWP发生变化，为保证TDD上行中心频点与下行中心频点一致，则上行BWP也需要发生变化；所述第三DCI指DL grant用于下行数据传输，所占的是非上行聚合传输的时隙。
在本申请的实施例中，UE还可以根据gNB发送的第三DCI中的BWP指示域与第四DCI中的BWP指示域是否相同来判断BWP是否发生切换。在一实施例中，当第三DCI中的BWP指示域与第四DCI中的BWP指示域不同时，确定BWP发生切换；当第三DCI中的BWP指示域与第四DCI中的BWP指示域相同时，确定BWP未发生切换。
例如，如图3所示为4时隙上行聚合传输示意图，在第一个U时隙前下发的DCI(DL grant)即所述第四DCI指示传输下行数据，第四DCI中的BWP指示域例如为10，表示使用BWP ID为3，在图中第一个D时隙发生BWP切换，UE在该时隙接收到DCI(DL grant)即所述第三DCI，第三DCI中的BWP指示域例如为01，表示使用BWP ID为2，则表明BWP发生切换，从BWP3变为BWP2，对于TDD帧结构，下行BWP发生变化，为保证TDD上下行中心频点一致，则上行BWP也需要发生变化；所述第三DCI和第四DCI指DL grant，用于下行数据传输，所占的是非上行聚合传输的时隙。
在本申请的实施例中，上述时隙聚合可以是上行时隙聚合，BWP可以是UL BWP；或者，时隙聚合可以是下行时隙聚合，BWP可以是DL BWP。
例如，对于TDD系统，由于需要保证DL BWP与UL BWP中心载频相同，因此，当DL BWP发生切换时，必然导致UL BWP发生切换；同样，当UL BWP发生切换时，必然导致DL BWP发生切换，那么，可以停止在后续时隙中传输数据。如图3所示，图中，U为上行时隙，D为下行时隙，假设聚合的时隙长度为4，并且，聚合的四个上行时隙中间穿插有聚合的四个下行时隙中的两个下行时隙，当在下行时隙传输过程中发生BWP切换时，则UE停止在后续两个上行时隙中传输数据，如图中画×的两个上行时隙。
又如，当切换前的BWP大于切换后的BWP时，如果切换前的BWP的资源块(Resource Block，RB)和切换后的BWP的RB之间无法完成映射，则需要停止在聚合的时隙中尚未传输的时隙中传输数据。
在一实施例中，该方法还包括：步骤201。
在步骤201中，根据第二下行控制信息指示在尚未传输的时隙中传输数据。
本申请的实施例中，在未传输的时隙中传输的数据与在已传输的时隙中传输的数据可以相同，也可以不相同。
如图4所示图中，U为上行时隙，D为下行时隙，假设聚合的时隙长度为4，并且，聚合的四个上行时隙中间穿插有聚合的四个下行时隙中的两个下行时隙，当在下行时隙传输过程中发生BWP切换时，则UE停止在后续两个上行时隙中传输数据，如图中画×的两个上行时隙。并且，根据第二下行控制信息(即图4中的调度(Grant)信令)在尚未传输的时隙中传输数据。
本申请实施例包括：当在进行时隙聚合传输过程中满足第一预设条件时，停止在聚合的时隙中尚未传输的时隙中传输数据。本申请实施例通过停止在聚 合的时隙中尚未传输的时隙中传输数据，从而不会导致聚合的时隙中尚未传输的时隙中的数据传输失败的问题，提高了在时隙聚合传输过程中发生BWP切换时时隙聚合传输的成功率。
参见图5，本申请另一个实施例提出了一种传输方法，包括：步骤500。
在步骤500中，当在进行时隙聚合传输过程中发生部分带宽切换时，将切换前的部分带宽映射到切换后的部分带宽，采用所述切换后的部分带宽在聚合的时隙中尚未传输的时隙中传输数据。
在本申请的实施例中，将切换前的部分带宽映射到切换后的部分带宽包括以下至少一种：
将所述切换前的部分带宽的第i个资源块映射到所述切换后的部分带宽的第i个资源块，其中，i为大于或等于0的整数；
将切换前的部分带宽的第i个资源块映射到切换后的部分带宽的第(i+△)或(i－△)个资源块；其中，i，△为大于或等于0的整数；
将所述切换前的部分带宽的第一资源块映射到所述切换后的部分带宽的第二资源块；其中，第一资源块的频域位置和第二资源块的频域位置相同；
将切换前的部分带宽的第i个资源块映射到切换后的部分带宽的第(i mod X)个资源块；其中，X为切换后的部分带宽的资源块的个数；
将所述切换前的部分带宽的资源块从所述切换后的部分带宽的最低资源块开始映射。
例如，当切换前的部分带宽小于或等于切换后的部分带宽时，将切换前的部分带宽的第i个资源块映射到切换后的部分带宽的第(i+△)或(i－△)个资源块；其中，i，△为大于或等于0的整数。如图6(a)所示，假设切换前的BWP包含(n+1)个RB，分别为RB0，RB1，……，RBn，切换后的BWP包含(m+1)个RB，分别为RB0，RB1，……，RBm，m大于n，分配给UE的RB包括RB2，RB3，RB4，……，RB(n－1)，那么，UE的RB2映射到切换后的BWP的RB2，UE的RB3映射到切换后的BWP的RB3，以此类推，UE的RB(n－1)映射到切换后的BWP的RB(n－1)。也就是说，上述△为0。
又如，如图6(b)所示，假设切换前的BWP包含(n+1)个RB，分别为RB0，RB1，……，RBn，切换后的BWP包含(m+1)个RB，分别为RB0，RB1，……，RBm，m大于n，分配给UE的RB包括RB2，RB3，RB4，……，RB(n－1)，那么，UE的RB2映射到切换后的BWP的RB4，UE的RB3映射到切换后的 BWP的RB5，以此类推，UE的RB(n－1)映射到切换后的BWP的RB(n+1)。也就是说，上述△为2。
从另一个角度，切换前的BWP的RB2的频域资源位置和切换后的BWP的RB4的频域资源位置相同，切换前的BWP的RB3的频域资源位置和切换后的BWP的RB5的频域资源位置相同，以此类推，切换前的BWP的RB(n-1)的频域资源位置和切换后的BWP的RB(n+1)的频域资源位置相同，那么，UE的RB2映射到切换后的BWP的RB4，UE的RB3映射到切换后的BWP的RB5，以此类推，UE的RB(n－1)映射到切换后的BWP的RB(n+1)。
又如，当切换前的部分带宽大于或等于切换后的部分带宽时，将切换前的部分带宽的第i个资源块映射到切换后的部分带宽的第(i mod X)个资源块；其中，X为切换后的部分带宽的资源块的个数。如图6(c)所示，假设切换前的BWP包含(m+1)个RB，分别为RB0，RB1，……，RBm，切换后的BWP包含(n+1)个RB，分别为RB0，RB1，……，RBn，m大于n，分配给UE的RB包括RB4，RB5，RB6，……，RB(n－2)，那么，UE的RB4映射到切换后的BWP的RB(4mod(n+1))，UE的RB5映射到切换后的BWP的RB(5mod(n+1))，以此类推，UE的RB(n－2)映射到切换后的BWP的RB((n－2)mod(n+1))。
又如，当切换前的部分带宽大于或等于切换后的部分带宽时，将切换前的部分带宽的资源块从切换后的部分带宽的最低资源块开始映射。
又如，切换前的BWP1为50个RB，切换后的BWP2变为20RB，BWP1中分配给UE用于上行数据传输的资源块数目为10，占用RB11-RB1120的频域位置，如果采用最低资源块映射的方法直接映射到BWP2中20RB中的RB0-RB9。
又如，当切换前的部分带宽大于或等于切换后的部分带宽时，如果资源块数量过多无法完成映射，可以以小带宽的BWP为准进行映射，UE或gNB进一步进行速率匹配，速率匹配指传输信道上的比特被打孔或重发，以匹配物理信道的承载能力，信道映射时达到传输所要求的比特速率；如切换前的BWP1为50个RB，切换后的BWP2变为10RB，BWP1中分配给UE用于上行数据传输的资源块数目为20，占用RB1-RB20的频域位置，那么只映射10RB，其他10RB不映射。
其他情况以此类推。
在一实施例中，将切换前的部分带宽映射到切换后的部分带宽后，该方法 还包括：
对所述切换后的部分带宽进行跳频(hopping)处理；
采用跳频处理后的切换后的部分带宽在所述尚未传输的时隙中传输数据。
在本申请的实施例中，对切换后的部分带宽进行跳频处理包括：
基于所述切换后的部分带宽的大小进行跳频计算。在一实施例中，
按照公式

其中，

Figure PCTCN2019080352-appb-000006
为切换后的BWP的带宽大小。
表1
Figure PCTCN2019080352-appb-000007
在本申请的实施例中，对所述切换后的部分带宽进行跳频处理之前，还包括：
重置跳频时隙计数器，或者，不重置跳频时隙计数器；
所述对切换后的部分带宽进行跳频处理包括：
根据重置的跳频时隙计数器或不重置的跳频时隙计数器对所述切换后的部分带宽进行跳频处理。
上述根据跳频时隙计数器对切换后的部分带宽进行跳频处理是指在对切换后的部分带宽进行跳频处理过程中所用到的当前的时隙号从时隙计数器获得，BWP切换后，时隙计数器可以重置或者不重置；例如，按照目前标准中的时隙间跳频方法，偶数时隙不跳频，奇数时隙跳频，对于四个时隙聚合传输，那么时隙计数器(0 1 2 3)增加，如果发生BWP切换，则可以保持不变，或者进行重置，如果第三个时隙发生BWP切换，则第三个时隙定时器从零开始计数变为(0 1 0 1)，如果第四个隙发生BWP切换，则第四个时隙定时器从零开始计数变为(0 1 2 0)，另外，所述时隙计数时也可能会包括非上行时隙(如下行时隙或特殊时隙S)，如图1所示的UUDDUU，计数分别为(012345)，如果时隙计数器因为BWP切换导致重置，计数可能变为(012012)。
在本申请的实施例中，上述切换后的频域偏置可通过原DCI中的跳频指示域补零或者截断指示。例如，当切换前的BWP的带宽小于50，而切换后的BWP的带宽大于或等于50时，频域偏置可以通过原DCI中跳频指示域补零指示。也就是说，切换前的频域偏置采用0和1指示，那么切换后的频域偏置可以采用00和01指示。
当切换前的BWP的带宽大于或等于50，而切换后的BWP的带宽小于50时，频域偏置可通过原DCI中跳频指示域截断指示。也就是说，切换前的频域偏置采用00、01、10和11指示，那么切换后的频域偏置可以采用0和1指示。
另外，在本申请的实施例中，时隙聚合传输中的第一个时隙的传输通过下行控制信息指示或者无线资源控制消息配置。
其中，第一DCI用于基于调度(grant based)传输，RRC消息用于免调度(grant free)传输。
例如，第一DCI动态指示时隙聚合传输中的第一个时隙的传输使用的频域资源、时域符号、调制编码方式、码流数、传输层数目、以及冗余版本(Redundancy Version，RV)号等。
又如，RRC半静态配置时隙聚合传输中的第一个时隙的传输使用的频域资源、使用时域符号、使用的调制编码方式、码流数、传输层数目、以及RV号等。
在本申请的实施例中，数据承载在以下任一种：

物理下行控制信道(Physical Downlink Control Channel，PDCCH)。
本申请实施例包括：当在进行时隙聚合传输过程中发生部分带宽切换时，将切换前的部分带宽映射到切换后的部分带宽，采用所述切换后的部分带宽在聚合的时隙中尚未传输的时隙中传输数据。本申请实施例采用切换后的部分带宽在聚合的时隙中尚未传输的时隙中传输数据，从而成功的进行所述尚未传输的时隙中的数据的传输，提高了在时隙聚合传输过程中发生BWP切换时时隙聚合传输的成功率。
参见图7，本申请另一个实施例提出了一种传输方法，包括：步骤700和步骤701。
在步骤700中，根据时域信息和频域信息中至少之一确定用于时隙聚合传输的合法时隙。
本申请的实施例中，时域信息包括以下至少之一：

Figure PCTCN2019080352-appb-000008
或者
Figure PCTCN2019080352-appb-000009
其中，n为调度DCI的时隙，K 0为调度DCI的时隙到接收下行数据的时隙之间的间隔，K 2为调度DCI的时隙到发送上行数据的时隙之间的间隔，μ PDSCH为物理下行共享信道(Physical Downlink Shared Channel，PDSCH)采用的子载波间隔，μ PDCCH为物理下行控制信道(Physical Downlink Control Channel，PDCCH)采用的子载波间隔。
例如，如图8(a)所示，假设要进行4时隙上行聚合传输，在第一个聚合时隙传输占用的时域符号是0-4，时域符号起始位置为第0个符号，时域符号持续长度为5个符号。图中，U为全下行符号时隙，D为全上行符号时隙，S为非全上行符号时隙。如果图8(a)所示的第二个S时隙的0-4符号中被下行符号 或者未知(unknown)符号占用，说明时域数据无法完成映射，如图8(b)所示，则认为该时隙不是合法时隙，无法进行时隙聚合传输，则跳过该时隙直接进一步判断下一个可用时隙，发现后一个U时隙中的0-4符号可用，则认为该时隙是合法时隙，可用于进行时隙聚合传输。
又如，通过SLIV指示在第一个聚合时隙传输占用的时域符号是0-6，时域符号起始位置为第0个符号，时域符号持续长度为7个符号，如果图8(a)所示的第二个S时隙的0-6符号可用，说明时域数据可以完成映射，则认为该时隙是合法时隙，可用于进行上行时隙聚合传输。
又如，由于发生BWP切换，由于BWP切换延迟的存在，导致在BWP转换时间内UE无法接收和发送数据，如图8(c)、8(d)所示，在BWP转换时间K2或K0内这些时隙为不合法时隙，不可用于进行上行时隙聚合传输，继续判断转换时间后的其他可用时隙。

部分带宽的大小；
切换后的部分带宽的大小；

例如，切换前的BWP与切换后的BWP大小不同，切换前的BWP大小为50RB，切换后的BWP大小为20RB，且资源分配为25RB，无法完全映射到切换后的BWP，则认为该时隙不是合法时隙，无法进行聚合传输。
又如，切换前的BWP与切换后的BWP子载波间隔不同，则认为该时隙不是合法时隙，无法进行聚合传输；或者，切换前的BWP与切换后的BWP频域位置不同，则认为该时隙不是合法时隙，无法进行聚合传输；或者，用于指示切换后的BWP的资源分配域配置为Null，则认为该时隙不是合法时隙，无法进行聚合传输；或者，用于指示切换后的BWP的资源分配域配置为预设状态，则认为该时隙不是合法时隙，例如资源分配域配置为全0或者全1，无法进行聚合传输。
在本申请的实施例中，时域信息和频域信息可以单独作为时隙是否为合格 时隙的判断指标，也可以联合作为时隙是否为合格时隙的判断指标。

例如，第一DCI动态指示时隙聚合传输中的第一个时隙的传输使用的频域资源、时域符号、调制编码方式、码流数、传输层数目、以及冗余版本(Redundancy Version，RV)号等。
又如，RRC半静态配置时隙聚合传输中的第一个时隙的传输使用的频域资源、使用时域符号、使用的调制编码方式、码流数、传输层数目、以及RV号等。
