背景技术
在新无线(New Radio，NR)技术中，通常用户设备(User Equipment,UE)依据基站的调度，在一个时隙中向基站发送一个传输块(Transmission Block,TB)。
最近NR考虑引入了一种新的数据传输机制，暂定为多时隙传输(TB over multiple slot,TBoMS)方式，也即一个TB通过多个时隙进行传输。基站需要接收UE在多个时隙发送的信号才能完整解析出UE发送的数据。这种方案主要为了提高覆盖范围，让UE在小区边缘利用这种机制可以可靠的传输数据。
但是，多时隙传输方式需要UE保持功率的稳定性，然而在实际传输过程中，UE可能因为某些原因不能保持传输功率的稳定，此时UE需要如何处理本次TBoMS是一个亟待解决的问题。

可选的，所述至少根据所述相对关系确定是否在当前传输时间间隔和/或后续的传输时间间隔内进行数据传输包括：如果所述相对关系表示所述差异值高于所述第一预设门限，则比较所述差异值是否达到第二预设门限；如果所述差异值达到第二预设门限，则取消在当前传输时间间隔进行数据传输，或者取消在当前传输时间间隔以及后续的传输时间间隔进行数据传输，所述第二预设门限大于所述第一预设门限。
可选的，所述至少根据所述相对关系确定是否在当前传输时间间隔和/或后续的传输时间间隔内进行数据传输：如果所述相对关系表示所述差异值达到所述第一预设门限，则确定当前传输间隔为功率减少的时间间隔；计算截止当前传输时间间隔，本次多时间间隔传输中传输数据的时间间隔中功率减少的时间间隔所占的比例；根据所述比 例确定是否在当前传输时间间隔和/或后续的传输时间间隔进行数据传输。
可选的，所述多时间间隔数据传输方法包括：如果所述比例达到预设比例，则取消在当前传输时间间隔和后续的传输时间间隔内进行数据传输；或者，如果所述比例小于所述预设比例，则继续在当前传输时间间隔内进行数据传输。

具体实施方式
如背景技术中所述，现有的多时隙传输方式需要UE保持功率的稳定性和相位的连续性，然而在实际传输过程中，UE可能因为某些原因不能保持传输功率的稳定，此时UE需要如何处理本次TBoMS(TB over multiple slot)是一个亟待解决的问题。
在本发明技术方案中，以多时间间隔传输一个传输块表示TBoMS，时间间隔可以以时隙(Slot)为单位，也可以以时隙内的部分符号(Symbol)长度为单位，时间间隔可以是时间上连续的，也可以是时间上不连续的。为简化起见，多时间间隔传输一个传输块简称为多时间间隔传输。UE的服务基站可以配置UE进行一次或多次多时间间隔传输，每次多时间间隔传输可以传输相同的数据块(即重传)或传输不同的数据块(即新传)。通过TBoMS传输是指在物理上行共享信道上进行传输，对于物理层来说，传输的是数据；对于高层来说，传输的内容可以是数据，也可以是高层信令，本文统称通过多时间间隔传输数据。
本发明技术方案中，用户设备在确定进行多时间间隔传输时，可以在每个传输时间间隔确定当前传输功率与初始传输功率的差异值，以及所述差异值与所述第一预设门限的相对关系，至少根据所述相对关系确定是否在当前传输时间间隔和/或后续的传输时间间隔内进行数据传输。也就是说，用户设备通过当前传输功率与初始传输功率的变化量大小能够确定以当前传输功率发送数据能否被基站成功解析，从而确定是否继续在当前传输时间间隔和/或后续的传输时间间隔内进行数据传输。在当前传输功率与初始传输功率的变化量较大的情况下，通过取消数据的传输来减少不必要的传输，降低用户设备的功耗以及减少对网络的干扰。
本方明技术方案可适用于5G(5 Generation)通信系统，还可适用于4G、3G通信系统，还可适用于未来新的各种通信系统，例如6G、7G等。
为使本发明的上述目的、特征和优点能够更为明显易懂，下面结合附图对本发明的具体实施例做详细的说明。
图1是本发明实施例一种多时间间隔数据传输方法的流程图。
本发明实施例的多时间间隔数据传输方法可以用于用户设备侧，也即可以由用户设备执行所述方法的各个步骤。
具体而言，所述多时间间隔数据传输方法可以包括以下步骤：
步骤S101：接收多时间间隔传输的传输参数，所述传输参数用于确定传输功率、传输时机，所述传输时机包括多个传输时间间隔；
服务基站可以在一条信令或多条信令中向用户设备传输多时间间隔传输的传输参数，可以是RRC信令和/或物理层下行控制信令。
步骤S102：在每个传输时间间隔确定当前传输功率与初始传输功率的差异值，以及所述差异值与所述第一预设门限的相对关系；
具体实施中，第一预设门限可以由协议预先设定，也可以由基站 配置给UE。初始传输功率是指UE在本次多时间间隔传输中，依据传输参数确定在首个时间间隔进行数据传输时的传输功率，依据传输参数确定传输功率属于现有技术，本文不展开描述，可以参考TS38.213。
本步骤中，每个传输时间间隔可以是本次多时间间隔传输中除首个时间间隔之外的其他传输时间间隔，也可以包含首个时间间隔，此时UE依据传输参数确定传输功率，在传输之前，如果因为其他原因如最大允许暴露(Maximum Permissible Exposure,MPE)限制需要降低首个时间间隔内的传输功率时，UE可以依据实际传输功率与UE根据传输参数确定的传输功率(也即初始传输功率)的差值确定功率的差异值。
步骤S103：至少根据所述相对关系确定是否在当前传输时间间隔和/或后续的传输时间间隔内进行数据传输。
需要指出的是，本实施例中各个步骤的序号并不代表对各个步骤的执行顺序的限定。
可以理解的是，在具体实施中，所述多时间间隔数据传输方法可以采用软件程序的方式实现，该软件程序运行于芯片或芯片模组内部集成的处理器中。该方法也可以采用软件结合硬件的方式实现，本申请不作限制。
本发明实施例应用于用户设备在多时间间隔数据传输过程中传输功率发生变化的场景，主要是用户设备的传输功率降低的场景。
本实施例中所称“传输时间间隔”是指服务基站动态或半静态调度资源的基本时间单位。具体可以是时隙(slot)、半时隙、或数个符号时长等。
本实施例中所称“多时间间隔数据传输”是指一个TB通过多个时间间隔进行传输。
下面以传输时间间隔为时隙为例进行说明，这种情况下，多时间 间隔数据传输即为多时隙传输块(TB over multiple slot,TBoMS)。本实施例中，UE接入服务小区，建立无线资源控制(Radio Resource Control,RRC)连接，开展业务。随着UE的移动，UE逐渐移动到小区边缘附近，UE所处的信道条件不好，因此服务基站配置UE采用TBoMS机制，即一个传输块通过多个时隙传输。多个时隙可以是连续的，也可以是不连续的，在每个时隙中，传输资源的位置可以相同，也可以不同。
基站在配置UE采用多时间间隔传输时，可以一并配置多时间间隔传输的传输参数，具体可以是多时间间隔传输采用的传输功率、传输时机。例如，服务基站配置UE通过8个时隙传输一个TB，传输功率为功率1。
那么在步骤S101的具体实施中，UE接收多时间间隔传输的传输参数。具体地，UE在收到通过TBoMS机制进行上行传输的调度指示时，按照确定的传输时机、传输功率进行传输，如UE需要在时隙1到时隙8共8个时隙中传输一个TB。
在具体实施中，最大允许暴露(Maximum Permissible Exposure,MPE)等因素会导致UE不能维持初始的传输功率。其中，MPE是指UE在接近人体时需要防止对人体产生大的电磁辐射，UE需要降低传输功率。如果UE降低传输功率，则很可能导致基站即使完整收到多个传输时间间隔，例如上述8个时隙中UE上传的信号，基站也解析不出UE发送的数据。
为了避免出现上述情况，在步骤S102和步骤S103的具体实施中，UE可以在每个传输时间间隔确定当前传输功率与初始传输功率的差异值，以及所述差异值与所述第一预设门限的相对关系，并至少根据所述相对关系确定是否在当前传输时间间隔和/或后续的传输时间间隔内进行数据传输。
具体实施中，当前传输功率与初始传输功率的差异值表示的是当前传输功率比初始传输功率减少的量或功率变化量的绝对值。通过该 差异值的相对大小，也即相对第一预设门限的大小，可以决定继续或取消数据传输。在当前传输时间间隔和/或后续的传输时间间隔内进行数据传输可以是指在当前传输时间间隔内进行数据传输，或者是在当前传输时间间隔及其之后的传输时间间隔内进行数据传输。
具体地，所述差异值可以通过初始传输功率(在本次多时间间隔传输中第一个时间间隔中的传输功率)减去当前传输功率(在本次多时间间隔传输中后续时间间隔中的传输功率)计算得到，所述差异值大于等于0。
需要说明的是，所述第一预设门限可以是由基站在配置多时间间隔传输时配置给UE的，例如通过RRC信令发送给UE；所述第一预设门限也可以是由通信标准协议来约定的。第一预设门限可以为大于等于0的数值，当第一预设门限为0时，UE在本次多时间间隔传输的每个传输时间间隔中，发现一旦传输功率与初始传输功率发生了变化(通常为减少)，即认为该时间间隔的传输为功率减少。
本发明技术方案中，用户设备通过当前传输功率与初始传输功率的变化量大小能够确定以当前传输功率发送数据能否被基站成功解析，从而确定是否继续在当前时间间隔和/或后续的传输时间间隔内进行数据传输。在当前传输功率与初始传输功率的变化量较大的情况下，通过取消数据的传输来减少不必要的传输，降低用户设备的功耗，减少对网络的干扰。
在一个非限制性的实施例中，如果所述相对关系表示所述差异值低于所述第一预设门限，则在当前传输时间间隔内进行数据传输。
本实施例中，每个传输时间间隔对应一个差异值。该差异值可以用于确定该传输时间间隔内数据的传输，或者用于确定该传输时间间隔之后的时间间隔内的数据传输。
本实施例中，差异值低于所述第一预设门限时，表示当前传输功率相对于初始传输功率减少的量较小，以当前传输功率发送数据能被 基站成功解析，故而可以继续在当前传输时间间隔内进行数据传输。
在一个非限制性的实施例中，如果所述相对关系表示所述差异值达到所述第一预设门限，则取消在当前传输时间间隔进行数据传输，或者取消在当前传输时间间隔和后续传输时间间隔进行数据传输。
本实施例中，差异值达到所述第一预设门限时，表示当前传输功率相对于初始传输功率减少的量较大，以当前传输功率发送数据不能被基站成功解析，故而取消在当前传输时间间隔和/或后续的传输时间间隔进行数据传输，以减少UE的功耗。
需要说明的是，在后续步骤中可以执行数据的重传等操作，以完成数据的传输，本发明实施例对此过程不再详细阐述。
在一个变化例中，如果所述相对关系表示所述差异值高于所述第一预设门限，则比较所述差异值是否达到第二预设门限；如果所述差异值达到第二预设门限，则取消在当前传输时间间隔进行数据传输、或者取消在当前传输时间间隔和后续的传输时间间隔进行数据传输，所述第二预设门限大于所述第一预设门限。
相对于前述实施例中采用同一门限，本发明实施例中采用第一预设门限和第二预设门限与差异值进行比较，实现多时间间隔数据传输的灵活性。
具体实施中，如果差异值高于所述第一预设门限并且低于第二预设门限，也即差异值处于第一预设门限和第二预设门限之间，则可以由UE自主决定是否在当前传输时间间隔和/或后续的传输时间间隔内进行数据传输。
在一个具体的应用场景中，基站配置UE在时隙1到时隙8共8个时隙中传输一个TB。UE在时隙1和时隙2执行了上行传输之后，发现不能维持初始传输功率进行数据传输。基站可以配置一个功率变化的门限(也即第一预设门限)。如果UE在之后的时隙中，如时隙3中需要降低传输功率，相对于TBoMS中初始传输功率，功率降低的 范围低于该门限，即UE减少传输功率的变化值低于该门限，则UE继续TBoMS的传输，依次传输后续几个时隙中的信号。基站收到8个时隙该UE传输的信号，可以正确解析出上行数据。UE在每个时隙均会判断功率变化值是否等于或超过该门限，然后执行相应的动作。
在另一个具体的应用场景中，基站还可以配置另一个功率变化的门限(也即第二预设门限)。如果UE发现在之后的时隙中需要降低的功率变化值等于或超过该门限，UE停止该时隙内数据的传输，或者UE停止该时隙及其之后时隙内数据的传输。UE在每个时隙均会判断功率变化值是否等于或超过该门限，然后执行相应的动作。
在一个非限制性的实施例中，请参照图2，图1所示步骤S103可以包括以下步骤：
步骤S201：如果所述相对关系表示所述差异值达到所述第一预设门限，则确定当前传输间隔为功率减少的时间间隔；
第一预设门限可以是大于等于0的数值。
步骤S202：计算截止当前传输时间间隔，本次多时间间隔传输中传输数据的时间间隔中功率减少的时间间隔所占的比例；
步骤S203：根据所述比例确定是否在当前传输时间间隔和后续的传输时间间隔进行数据传输。
本实施例中，在计算所述比例时，可以是以本次多时间间隔传输的总时间间隔的数量作为分母；或者以截止当前传输时间间隔已传输数据的时间间隔次数作为分母。例如，基站配置UE在时隙1到时隙8共8个时隙中传输一个TB，UE发现时隙3到时隙6均发生了功率减少，此时分母可以是8，也可以是6。
进一步地，步骤S203可以包括以下步骤：如果所述比例达到预设比例，则取消在当前传输时间间隔和后续的传输时间间隔内进行数据传输；或者，如果所述比例小于所述预设比例，则继续在当前传输 时间间隔进行数据传输，或者继续在当前传输时间间隔和后续的传输时间间隔内进行数据传输。
相对于前述实施例中根据每个传输时间间隔对应的差异值确定数据传输，本发明实施例是根据多个已传输数据的时间间隔内功率减少的时间间隔所占的比例来确定的。
本发明实施例中，UE在确定功率减少的时间间隔时，可以依据前述实施例中的第一预设门限，例如，当前传输时间间隔的当前传输功率与初始传输功率的差异值，也即减少量低于第一预设门限时，UE不统计该传输时间间隔为功率减少的时间间隔；只有当功率减少数值等于或超过第一预设门限时，才统计该传输时间间隔为功率减少的时间间隔。
在一个变化例中，也可以依据前述实施例中的第二预设门限确定功率减少的时间间隔，例如，一个时隙中的功率减少量低于第二预设门限，UE不统计该时隙的功率变化为功率减少；只有当功率减少数值等于或超过第二预设门限时，才统计该时隙的功率变化为功率减少。
具体实施中，在功率减少的时间间隔所占的比例达到预设比例的情况下，也即很大比例的传输信号低于初始的传输功率时，基站侧不能很好的复原信号，不能顺利解析上行信号。此时UE继续传输，只会增加UE的功率消耗，因此UE可以取消数据传输，以减少不必要的数据传输，降低功耗。
在一个具体的应用场景中，基站配置UE在时隙1到时隙8共8个时隙中传输一个TB。UE在时隙1到时隙8采用TBoMS机制，UE发现功率减少或不传输的时隙数占据该TB上传的总时隙达到一定比例，比如发现TBoMS原本是在8个时隙上进行传输，当前已经发现有4个时隙的传输因为MPE减少了传输功率或不传输，到达了预设比例50％，UE停止剩余时隙的传输。比如UE发现时隙3到时隙6均发生了功率减少，UE取消时隙7和时隙8的传输。
在本发明一个非限制性的实施例中，UE在接收到重新分配的资源时，至少根据所述相对关系上报功率指示信息，以指示传输功率减少。
本实施例中，UE可以向基站上报功率传输减少的信息，以便基站合理调度后续上行传输资源，比如可以减少分配的资源数量，以适应传输功率的减少。
具体实施中，在MPE导致的UE的实际传输功率减小的情况持续存在的情况下，UE可以在确定差异值达到第一预设门限时，向基站上报功率指示信息。基站通过减少为UE分配的资源数量来降低所需的传输功率，以与UE当前的传输功率相匹配，提升数据传输效率。
请参照图3，本发明实施例还公开了一种多时间间隔数据传输装置30。多时间间隔数据传输装置30可以包括：
传输参数接收模块301，用于接收多时间间隔传输的传输参数，所述传输参数用于确定传输功率和传输时机，所述传输时机包括多个传输时间间隔；
差异确定模块302，用于在每个传输时间间隔确定当前传输功率与初始传输功率的差异值，以及所述差异值与第一预设门限的相对关系；
数据传输模块303，用于至少根据所述相对关系确定是否在当前传输时间间隔和/或后续的传输时间间隔内进行数据传输。
本发明实施例中，通过当前传输功率与初始传输功率的变化量大小能够确定以当前传输功率发送数据能否被基站成功解析，从而确定是否继续在当前传输时间间隔和/或后续的传输时间间隔内进行数据传输。本发明实施例能够在多时间间隔传输的传输功率不稳定的场景下，在确保传输效率的情况下，兼顾UE的功率消耗，避免不必要的传输。
