具体实施方式
现结合附图和具体实施方式对本公开实施例进一步说明。
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公开实施例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、本公开的一些方面相一致的装置和方法的例子。
需要说明的是，本公开的一个实施例中可以包括多个步骤；为了便于描述，这些步骤被进行了编号；但是这些编号并非是对步骤之间执行时隙、执行顺序的限定；这些步骤可以以任意的顺序被实施，本公开实施例并不对此作出限定。
在判断是否开启基于RACH的小数据包传输SDT时，需要基于用户设备接收的信号强度，例如SS-RSRP，进行判断。即，保证只有在良好的覆盖条件下才执行小数据包传输SDT的传输，以免造成上行传输资源的浪费。
另外，对于基于RACH的小数据包传输SDT，选择基于2-step RACH的小数据包传输SDT还是选择基于4-step RACH的小数据包传输SDT，也需要基于用户设备接收的信号强度进行判断。
在release-17中，由于引入了覆盖增强(Coverage Enhancement，CE)的功能，因此希望即使处于小区边缘信号覆盖较差的用户设备，也能够使用小数据包传输SDT以减少功耗和资源开销，同时减少数据传输时延。
因此，为了使得具有CE能力的用户设备能够在小区边缘执行小数据包传输SDT，提出了本申请的方法。
本公开实施例提供了一种执行小数据包传输SDT的方法，该方法被用户设备执行；该方法可以独立被执行，也可以结合本公开实施例的任意一个其他实施例一起被执行。图1是根据一示例性实施例示出的一种执行小数据包传输SDT的方法的流程图，如图1所示，该方法包括：
步骤101，测量下行信号的信号强度；
步骤102，基于用户设备是否具备覆盖增强CE能力，获取与小数据包传输SDT相关的与用户设备对应的信号强度阈值；
步骤103，基于信号强度和信号强度阈值，执行小数据包传输SDT。
在一个实施方式中，用户设备测量下行信号的信号强度，该信号强度为同步信号-参考信号接收功率(Synchronization Signal-Reference Signal Receiving power，SS-RSRP)。
在一个实施方式中，用户设备基于其是否具有CE能力，来获取相应的阈值。在一个实施方式中，用户设备从基站接收的信令来获取该阈值。在一实施方式中，用户设备基于协议规定来获取该阈值。这里的阈值用于用户判断是否执行小数据包传输SDT，以及在执行小数据包传输SDT时采用的具体方式，例如基于2-step RACH的小数据包传输SDT、基于4-step RACH的小数据包传输SDT。
在一个实施方式中，用户设备基于其是否具有CE能力以及信号强度与阈值的大小关系，执行小数据包传输SDT。
在该实施方式中，用户设备确定执行小数据包传输SDT时，在考虑用户设备接收的信号强度的同时，也参考其CE能力，从而适用于具有CE能力的用户设备执行小数据包传输SDT。
本公开实施例提供了一种执行小数据包传输SDT的方法，该方法被用户设备执行；该方法可以独立被执行，也可以结合本公开实施例的任意一个其他实施例一起被执行。图2是根据一示例性实施例示出的一种执行小数据包传输SDT的方法的流程图，如图2所示， 该方法包括：
步骤201，测量下行信号的信号强度；
步骤202，响应于用户设备具有覆盖增强CE能力，获取第一阈值作为该用户设备的信号强度阈值；
步骤203，基于信号强度和信号强度阈值，执行小数据包传输SDT。
在一个实施方式中，用户设备测量下行信号的信号强度，该信号强度为SS-RSRP。在一个实施方式中，用户设备基于从基站接收的信令来获取阈值。在一实施方式中，用户设备基于协议规定来获取阈值。
在一个实施方式中，当用户设备具有CE能力时，获取第一阈值，基于信号强度和第一阈值的关系，确定是否执行小数据包传输SDT。
本公开实施例提供了一种执行小数据包传输SDT的方法，该方法被用户设备执行；该方法可以独立被执行，也可以结合本公开实施例的任意一个其他实施例一起被执行。图3是根据一示例性实施例示出的一种执行小数据包传输SDT的方法的流程图，如图3所示，该方法包括：
步骤301，测量下行信号的信号强度；
步骤302，响应于用户设备不具有覆盖增强CE能力，获取第二阈值作为用户设备的信号强度阈值；
步骤303，基于信号强度和信号强度阈值，执行小数据包传输SDT。
在一个实施方式中，用户设备测量下行信号的信号强度，该信号强度为SS-RSRP。在一个实施方式中，用户设备基于从基站接收的信令来获取阈值。在一实施方式中，用户设备基于协议规定来获取阈值。
在一个实施方式中，当用户设备不具有CE能力时，获取第二阈值，基于信号强度和第二阈值的关系，确定是否执行小数据包传输SDT。
本公开实施例提供了一种执行小数据包传输SDT的方法，该方法被用户设备执行；该方法可以独立被执行，也可以结合本公开实施例的任意一个其他实施例一起被执行。图4是根据一示例性实施例示出的一种执行小数据包传输SDT的方法的流程图，如图4所示，该方法包括：
步骤401，测量下行信号的信号强度；
步骤402，响应于用户设备具有覆盖增强CE能力，获取第一阈值作为该用户设备的信号强度阈值；
步骤403，响应于信号强度大于或等于第一阈值，执行基于4步RACH的小数据包传输SDT。
在一个实施方式中，用户设备测量下行信号的信号强度，该信号强度为SS-RSRP。在一个实施方式中，用户设备基于从基站接收的信令来获取阈值。在一实施方式中，用户设备基于协议规定来获取阈值。
在一个实施方式中，当用户设备具有CE能力时，获取第一阈值，当信号强度大于或 等于第一阈值时，执行基于4步RACH的小数据包传输SDT。在一个实施方式中，当信号强度小于第一阈值时，表明信号强度较差，则不执行小数据包传输SDT。
在一个实施方式中，第一阈值小于上文中的第二阈值，这是因为，对于具有CE能力的用户设备，其位于小区边缘，即信号覆盖较差的环境中，也能执行小数据包传输SDT。
在该实施方式中，对于具有CE能力的用户设备，将其接收信号的信号强度与较低的阈值相比较来确定是否执行小数据包传输SDT，可以能够充分利用用户设备的CE能力，使得其能够在基站信号覆盖较差的地方也能执行小数据包传输SDT，从而减少功耗和资源开销，同时减少数据传输时延。
本公开实施例提供了一种执行小数据包传输SDT的方法，该方法被用户设备执行；该方法可以独立被执行，也可以结合本公开实施例的任意一个其他实施例一起被执行。图5是根据一示例性实施例示出的一种执行小数据包传输SDT的方法的流程图，如图5所示，该方法包括：
步骤501，测量下行信号的信号强度；
步骤502，响应于用户设备不具有覆盖增强CE能力，获取第二阈值作为用户设备的信号强度阈值；
步骤503，响应于信号强度大于或等于第二阈值，执行基于4步RACH的小数据包传输SDT。
在一个实施方式中，用户设备测量下行信号的信号强度，该信号强度为SS-RSRP。在一个实施方式中，用户设备基于从基站接收的信令来获取阈值。在一实施方式中，用户设备基于协议规定来获取阈值。
在一个实施方式中，当用户设备不具有CE能力时，获取第二阈值，当信号强度大于或等于第二阈值，执行基于4步RACH的小数据包传输SDT。在一个实施方式中，当信号强度小于第二阈值时，表明信号强度较差，则不执行小数据包传输SDT。
在一个实施方式中，第二阈值大于上文中的第一阈值，这是因为，对于不具有CE能力的用户设备，其位于信号覆盖较差的环境中时，由于没有CE能力来补偿较差的下行信号的信号强度，因此需要将判断是否执行小数据包传输SDT的阈值设定得比第一阈值高，从而保证通信质量。
本公开实施例提供了一种执行小数据包传输SDT的方法，该方法被用户设备执行；该方法可以独立被执行，也可以结合本公开实施例的任意一个其他实施例一起被执行。其中，第一阈值小于第二阈值。
其中第一阈值用于判断具有CE能力的用户设备是否执行小数据包传输SDT，第二阈值用于判断不具有CE能力的用户设备是否执行小数据包传输SDT。第一阈值小于第二阈值是因为，对于具有CE能力的用户设备，其位于信号覆盖较差的环境中，也能执行小数据包传输SDT，从而减少功耗和资源开销，同时减少数据传输时延。
本公开实施例提供了一种执行小数据包传输SDT的方法，该方法被用户设备执行；该 方法可以独立被执行，也可以结合本公开实施例的任意一个其他实施例一起被执行。图6是根据一示例性实施例示出的一种执行小数据包传输SDT的方法的流程图，如图6所示，该方法包括：
步骤601，测量下行信号的信号强度；
步骤602，响应于用户设备具备覆盖增强CE能力，获取第一阈值和第三阈值作为用户设备的信号强度阈值；
步骤603，响应于信号强度大于或等于第一阈值且小于第三阈值，开启用户设备的覆盖增强CE能力，并执行小数据包传输SDT。
在一个实施方式中，用户设备测量下行信号的信号强度，该信号强度为SS-RSRP。在一个实施方式中，用户设备基于从基站接收的信令来获取与小数据包传输SDT相关的阈值。在一实施方式中，用户设备基于协议规定来获取与小数据包传输SDT相关的阈值。
在一个实施方式中，当用户设备具有CE能力时，若信号强度大于或等于第一阈值且小于第三阈值，则执行基于4步RACH的小数据包传输SDT，第一阈值小于第三阈值。这里，信号强度小于第三阈值，表明用户设备接收信号的信号强度不是足够大，此时为了保证通信质量，则需要用户设备开启CE能力，例如启动重传(Repetition)功能。
在一个实施方式中，第三阈值等于判断不具有CE能力的用户设备是否能够执行小数据包传输SDT时所基于的第二阈值。在一个实施方式中，第三阈值大于第二阈值。
在该实施方式中，对于具有CE能力的用户设备，当其接收信号的信号强度指示其能够执行小数据包传输SDT，但该信号强度又不足够大时，该用户设备开启CE能力，通过开启CE能力来弥补基站信号覆盖的不足，从而通过执行小数据包传输SDT，来实现减少功耗和资源开销、同时减少数据传输时延的目的。

在一个实施方式中，当用户设备具有CE能力时，若信号强度大于或等于第三阈值且小于第四阈值，则执行基于4步RACH的小数据包传输SDT，这里的第三阈值小于第四阈值。这里，信号强度大于第三阈值，表明用户设备接收信号的信号强度足够大，此时不需要用户设备执行CE，即能保证一定的通信质量。
在该实施方式中，对于具有CE能力的用户设备，当其接收信号的信号强度指示其能够执行小数据包传输SDT，且该信号强度足够大时，该用户设备执行小数据包传输SDT，且不需开启CE能力，从而实现减少功耗和资源开销、同时减少数据传输时延的目的。
