具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本发明相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本发明的一些方面相一致的装置和方法的例子。
图1A是根据一示例性实施例示出的确定传输时间间隔的方法的流程图，图1B是根据图1A所示实施例示出的一种确定传输时间间隔的方法的场景图；该确定传输时间间隔的方法可以应用在基站上，如图1A所示，该确定传输时间间隔的方法包括以下步骤101-103：
在步骤101中，确定UE所使用的数据业务的类型。
在一实施例中，基站基于与用户设备(User Equipment，简称为UE)之间的数据业务交互，可以获知UE当前的数据业务的类型，数据业务的类型例如为eMBB、mMTC、URLLC等。
在步骤102中，基于UE所使用的数据业务的类型，为UE分配第一TTI对应的第一长度信息和所述第一TTI对应的载波频率。
在一实施例中，若数据业务的类型表示低时延的业务类型，基站可以为UE分配较小长度值的第一TTI，例如，0.5毫秒，若数据业务的类型表示高时延的业务类型，则基站可以为UE分配较大长度值的第一TTI，例如，4毫秒。此外，基站还可以基于小区内资源的使用情况，为UE分配一个可用的载波频率，从而使UE能够正常工作在该载波频率上，避免使用不适当的载波频率导致对小区内的其他UE形成干扰。
在步骤103中，向UE发送下行控制信令，其中，下行控制信令中携带有第一长度信息和第一TTI对应的载波频率。
在一实施例中，下行控制信令可以通过物理下行控制信道(Physical Downlink  Control Channel，简称为PDCCH)发送给UE，通过将第一TTI对应的第一长度信息和第一TTI对应的载波频率写入PDCCH中的设定字段即可。
在一实施例中，第一长度信息可以为具体的长度值，例如，第一长度信息为1毫秒，第一长度信息也可以为长度值对应的标号，例如，第一长度信息为数字“01”，表示长度值1毫秒，数字“10”时，表示长度值5毫秒，在此情形下，只要基站和UE双方预先约定标号所对应的长度值即可。
在一示例性场景中，如图1B所示，以移动网络为长期演进(Long Term Evolution，简称为LTE)网络并且基站为演进型基站(eNB)为例进行示例性说明，在图1B所示的场景中，包括eNB10、eNB20以及UE30、以及，其中，eNB10下覆盖多个小区，图1B仅示例性示出小区11，eNB20下覆盖多个小区，图1B仅示例性示出小区12，其中，eNB20为eNB10的相邻基站。eNB10可以基于当前小区11内的UE的数据业务的类型以及小区11当前所使用的时频资源，为小区内的UE分配与UE的数据业务的类型相匹配的TTI。例如，当UE30在小区11中已经接入到eNB10时，UE30当前所使用的数据业务为mMTC，对应低时延的业务类型，UE30可以基于eNB10提供的一个基准TTI(例如，1毫秒长度的TTI)解调PDCCH，从PDCCH中解调出UE30能够使用的较佳的TTI(例如，0.5毫秒)以及相应的载波频率(例如，100MHz)后，UE30将频率调整到100MHz并且将长度为1毫秒的TTI调整到长度为0.5毫秒的TTI。
本实施例中，由于基站可以结合UE所使用的数据业务的类型为UE分配一个第一TTI，进而使UE对时延敏感的数据业务采用较短长度的TTI，而对时延不敏感的数据业务可以适当采用较长长度值的TTI，确保UE在处理数据业务时能够灵活地调整TTI的长度值。
图2A是根据另一示例性实施例示出的确定传输时间间隔的方法的流程图，图2B是根据图2A所示实施例示出的TTI的长度的示意图之一，图2C是根据图2A所示实施例示出的TTI的长度的示意图之二，图2D是根据图2A所示实施例示出的TTI的长度的示意图之三；本实施例利用本公开实施例提供的上述方法，以基站如何控制UE接入为例并结合图1B进行示例性说明，如图2A所示，包括如下步骤：
在步骤201中，确定基站在预设频率范围的第二TTI对应的第二长度信息，其中，预设频段范围位于基站的载波所在的频段中。
在一实施例中，预设频段范围内所使用的传输时间间隔是固定值，例如1ms。在一实施例中，预设频段范围可以位于基站的载波所在的频段中的中心频段，预设频 段范围可以与预设网络的频段相一致，预设网络例如LTE网络，例如，基站的载波所在的频段为100MHz-180MHz，则预设频段范围为130MHz-150MHz，本领域技术人员可以理解的是，上述频段范围的数字仅为便于理解本公开的技术方案所作出的示例性说明，载波具体的频段以及预设频段范围可以基于不同的通信协议来确定，本公开对具体数字不做限制。
在一实施例中，第二TTI可以为基站提供的一个默认TTI，该默认的TTI可以相对第一TTI作为一个基准TTI，即，UE通过该基准TTI接入到基站，之后，再基于具体的数据业务的类型，调整到合适UE自身的TTI(即，本公开中所述的第一TTI)。
在步骤202中，向小区发送广播信令，其中，第二长度信息携带在广播信令中。
在步骤203中，在UE基于广播信令中携带的第二长度信息接入基站后，确定UE所使用的数据业务的类型。
在步骤204中，基于UE所使用的数据业务的类型，为UE分配第一TTI对应的第一长度信息和第一TTI对应的载波频率。
在步骤205中，向UE发送下行控制信令，其中，下行控制信令中携带有第一长度信息和第一TTI对应的载波频率。
步骤203-步骤205的描述可以参考上述图1A所示实施例的描述，在此不再详述。
下面对第一TTI与第二TTI的长度值之间的关系进行说明。
如图2B所示，为本公开中的第二TTI，其中，标号21表示物理下行控制信道(Physical Downlink Control Channel，简称为PDCCH)，标号22表示物理下行共享信道(Physical Downlink Shared Channel，简称为PDSCH)，图2B所示的第二TTI的长度值例如为1毫秒。图2C所示为基站为UE分配的第一TTI，该第一TTI与第二TTI之间的长度值成两倍的比例关系，即，在图2B所示的第二TTI的长度值为1毫秒的情形下，图2C所示的第一TTI为2毫秒；图2D所示为第一TTI的另一个长度值，该第一TTI与第二TTI之间的长度值成二分之一的比例关系，即，在图2B所示的第二TTI的长度值为1毫秒的情形下，图2D所示的第一TTI的长度值为1/2毫秒。需要说明的是，图2B-图2D所示的TTI的长度值仅为示例性说明，当基站基于实际的业务需求为UE分配了不同长度值的TTI时，UE同样也可以从下行控制信令中解析出不同长度值的TTI，其中，第一TTI的长度值是第二TTI的长度值的整数倍或者是整数分之一；进一步地，第一TTI的长度值是第二TTI的长度值的2的n次方倍或者2的n次方分之一，其中，n为正整数，在第一TTI的长度值是第二TTI的长度值的2的n 次方倍或者2的n次方分之一的情形下，可以尽量减小PDSCH对PDCCH的干扰点。
本实施例中，基站先通过广播信令使UE获知基站在预设频率范围的第二TTI对应的第二长度信息，基于该第二长度信息所表示的长度值，解析下行控制信令，进而得到适合UE自身的第一TTI的第一长度信息，从而可以确保UE基于数据业务的需求灵活使用时频资源，避免UE丢掉相关的业务数据。
图3A是根据再一示例性实施例示出的确定传输时间间隔的方法的流程图，图3B根据图3A所示实施例示出的TTI的长度的示意图之一，图3C是图3A所示实施例示出的TTI的长度的示意图之二，图3D是图3A所示实施例示出的TTI的长度的示意图之三；本实施例利用本公开实施例提供的上述方法，以如何设置相邻载波中的TTI中相互重叠的第一时频资源位置为例并结合图1B进行示例性说明，如图3A所示，包括如下步骤：
在步骤301中，在基站提供的至少一个TTI中，确定基站的载波所在的频段中位于预设频段范围外的相邻两个载波，其中，预设频段范围位于基站的载波所在的频段中。
在一实施例中，预设频段范围内所使用的传输时间间隔是固定值，例如1ms。
与上述图2A所示实施例的示例性描述相对应，基站的载波所在的频段为100MHz-180MHz，则预设频段范围为130MHz-150MHz，则基站的载波所在的频段中位于预设频段范围外的频率范围包括100MHz-130MHz和150MHz-180MHz，相邻两个载波位于100MHz-130MHz或者150MHz-180MHz中。
在步骤302中，确定相邻两个载波各自对应的TTI中的其中一个TTI的物理下行共享信道与另一个TTI的物理下行控制信道的第一时频资源。
在步骤303中，将位于其中一个TTI的物理下行共享信道中的第一时频资源设置为空。
下面结合图3B-图3D进行示例性说明，图3B-图3D所示的TTI均为eNB10所采用的TTI，其中，图3B和图3D示出的是不同长度值的第一TTI，图3B所示为一个第一TTI，长度为2毫秒，包括PDCCH311和PDSCH32，图3D所示为四个连续的第一TTI，长度为0.5毫秒，每一个第一TTI包括PDCCH331和PDSCH34；图3C示出的是两个连续的第二TTI，长度为1毫秒，每一个第二TTI包括PDCCH321和PDSCH33，为了简明起见，图3B-图3D中具有相同意义的部分不再重复标记。
在图1B所示的小区11中，其中一个UE(命名为第一UE)在基于图3B所示的第二TTI传输控制信令和业务数据，另一个UE(命名为第二UE)基于图3C所示 的第二TTI传输控制信令和业务数据，并且第一UE和第二UE通过相邻载波传输业务数据，例如，第一UE使用载波的频率为100MHz，第二UE使用载波的频率为101MHz。由于图3B所示的第二TTI的长度值大于图3C所示的第一TTI的长度值，第二TTI中的PDSCH会对第一TTI中的PDCCH形成干扰，为了避免图3B中的PDSCH对图3C中的PDCCH形成干扰，可确定出图3B所示的PDSCH与图3C所示的PDDCH相互重叠的第一时频资源位置，如图3B所示PDSCH32中标号312、标号313和标号314对应的位置，将图3B所示的PDSCH中的标号312、标号313和标号314对应的位置设置为空(blank)，其中，第一时频资源位置可以为PDSCH32中的子帧、时隙或者小时隙(Min slot)、符号等时频资源所在的位置。
类似地，当第一UE和第二UE在相邻的载波上分别采用图3B和图3C所示的TTI传输数据时，可以将图3C中的标号322、标号324所示的第一时频资源位置设置为空，从而避免图3C对图3D中的控制信令产生干扰。
本实施例中，通过将位于其中一个TTI的PDSCH中的第一时频资源位置设置为空，可以避免业务数据对其它TTI的控制信令产生干扰，提高基站在控制UE时的可靠性。
图4A根据再一示例性实施例示出的确定传输时间间隔的方法的流程图，图4B根据图4A所示实施例示出的TTI的长度的示意图之一，图4C是图4A所示实施例示出的TTI的长度的示意图之二；本实施例利用本公开实施例提供的上述方法，以如何设置相邻载波中的TTI中相互重叠的第一时频资源位置为例并结合图1B进行示例性说明，如图4A所示，包括如下步骤：
在步骤401中，确定基站与该基站的相邻基站所采用的相邻载波以及相邻载波各自使用的TTI。
在一实施例中，eNB10可以基于X2接口获取到eNB20所使用的TTI的长度值信息。为了避免基站对相邻基站的相邻载波产生干扰，可以确定基站以及相邻基站各自所使用的TTI，并确定各自所使用的TTI对应的载波。
在步骤402中，在相邻载波各自使用的TTI中，确定其中一个TTI的物理下行共享信道与另一个TTI的物理下行控制信道相互重叠的第二时频资源位置。
在步骤403中，将位于其中一个TTI的物理下行共享信道中的第二时频资源位置设置为空。
下面结合图4B-图4C进行示例性说明，图4B所示的TTI为eNB10所采用的TTI，图4C所示的TTI为eNB20所采用的TTI，其中，图4B所示为一个第二TTI， 长度为2毫秒，包括PDCCH411和PDSCH42，图4C所示为两个连续的第二TTI，长度为1毫秒，每一个第二TTI包括PDCCH421和PDSCH43。
在图1B所示的小区11中，其中一个UE(命名为第一UE)在基于图4B所示的第二TTI传输控制信令和业务数据，在小区12中，另一个UE(命名为第三UE)基于图4C所示的第二TTI传输控制信令和业务数据，并且第一UE和第三UE通过相邻载波传输业务数据，例如，第一UE使用载波的频率为100MHz，第三UE使用载波的频率为101MHz。由于图4B所示的第二TTI的长度值大于图4C所示的第二TTI的长度值，图4B所示第二TTI中的PDSCH会对图4C所示的第二TTI中的PDCCH形成干扰，为了避免图4B中的PDSCH对图4C所示的PDCCH形成干扰，可确定出图4B所示的PDSCH与图4C所示的PDDCH相互重叠的第二时频资源位置，如图4B所示PDSCH32中标号412对应的位置，将图4B所示的PDSCH中的标号412对应的位置设置为空(blank)，其中，第二时频资源位置可以为PDSCH42中的子帧、时隙或者小时隙(Min slot)、符号等时频资源所在的位置。
需要说明的是，图4B和图4C仅为一个示例性说明，对于不同长度值的TTI，可以通过上述类似的方式，将PDSCH中的相互重叠的时频资源位置设置为空，从而可以避免对其它TTI中的相互重叠的控制信令形成干扰。
本实施例中，将位于任意一个传输时间间隔的物理下行控制信道中的第二重叠符号位置设置为空，可以避免基站在传输业务数据的过程中，对相邻基站在传输控制信令时产生干扰，提高相邻基站在控制其对应UE时的可靠性。
图5是根据又一示例性实施例示出的确定传输时间间隔的方法的流程图；该数据传输方法可以应用在UE上，本实施例结合图1B进行示例性说明，如图5所示，该确定传输时间间隔的方法包括以下步骤501-503：

关于第一TTI与第二TTI之间的长度关系，可以参见上述图2A所示实施例的相关描述，在此不再详述。
本实施例中，基于不同的数据业务采用不同长度的TTI，可以确保UE对时延敏感的数据业务能够采用较短长度的TTI，对时延不敏感的数据业务可以适当采用较长长度的TTI，使UE在处理数据业务时能够灵活地调整TTI的长度值。
