Description

抢占时频资源的确定方法及装置、用户设备和基站 技术领域
本公开涉及通信技术领域，尤其涉及一种抢占时频资源的确定方法及装置、用户设备、基站和计算机可读存储介质。
背景技术
随着通信技术的发展，出现了第五代移动通信技术(5th Generation，简称5G)。5G目前的业务类型至少包括增强移动宽带(enhanced Mobile Broad Band，简称eMBB)、海量机器类通信(massive Machine Type Communication，简称mMTC)、超高可靠与低延迟的通信(Ultra Reliable Low Latency Communication，简称URLLC)等多种类型。这些业务同属数据业务，但对时延和可靠性的要求各不相同，例如URLLC业务用于车联网等需要低时延的领域，对及时性要求很高，建立业务时需要及时，甚至对之前的业务具有抢占性。而mMTC业务则通常对时延并不敏感，可以间隔较长时间送达数据。实现对时延敏感业务有效传输的一种方式是改进混合自动重传请求(Hybrid Automatic Repeat reQuest，简称HARQ)的传输，例如，使得重传反馈更快更准确。
长期演进(Long Term Evolution，简称LTE)中是以传输块(Transmission Block，简称TB)为单位进行HARQ反馈，每个TB反馈1比特(bit)的应答(ACK)或者非应答(NACK)消息。为了提高重传准确率，第三代合作伙伴计划(3GPP)提出基于代码块组(Code Block Group，简称CBG)进行重传，CBG是TB中更小的数据单元单位，一个CBG对应1bit的ACK或者NACK反馈，由于重传的颗粒度将更小，因此可以更精确地反映错误传输的位置，进而使得重传更准确，而由于需要重传的数据量更小，因此，重传效率更高。
但是，如果出现业务抢占(preemption)的情况，例如，当eMBB业务已经开始传输或即将开始传输时，URLLC业务来临，则URLLC会抢占eMBB的传输时频资源，导致原有eMBB业务在HARQ反馈时错误地认为eMBB数据传输错误，从而丢弃有用的URLLC数据。而如何判断URLLC抢占eMBB的时频资源是需要解决的一个技术问题。

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是本申请一示例性实施例示出的一种抢占时频资源的确定方法的流程图，该实施例从用户设备(UE)侧进行描述，如图1A所示，抢占时频资源的确定方法包括：
在步骤S101中，接收并读取基站发送的第一业务数据。
在该实施例中，UE可以按照预设资源单元接收基站发送的第一业务数据，其中，预设资源单元可以包括但不局限于子帧(subframe)、时隙(slot)、符号(symbol)和代码块组(CBG)等，第一业务数据可以包括但不局限于eMBB数据。
在步骤S103中，若确定存在接收失败的第一业务数据，则确定接收失败的第一业务数据对应的时频资源区域，并对时频资源区域及其相关时频资源区域的部分或全部业务数据进行解密。
其中，业务数据对应的时频资源区域是指该业务数据所占用的时域资源和频域资源所对应的区域。某个时频资源区域的相关时频资源区域是指与该时频资源区域的时域和频域中的至少一项相关的时频资源区域，某个时频资源区域及其相关时频资源区域通常共用某些控制信息，这些控制信息可以包括但不局限于在时间和频率上周期出现的控制信息，例如同步信号或参考信号等，相关时频资源区域可以包括但不局限于该时频资源区域的邻近时频资源区域。如图1B所示，接收失败的第一业务数据对应的时频资源区域是CBG4对应的时频资源区域，CBG4对应的时频资源区域的邻近时频资源区域为图1B中的时频资源区域X。包括但不限于时间和频率上周期出现的控制信息，如同步信号、参考信号等。
在该实施例中，对时频资源区域及其相关时频资源区域的部分或全部业务数据进行解密可以包括但不局限于以下任一项：
1)使用预设扰码对时频资源区域及其相关时频资源区域的部分或全部业务数据进行解扰。
其中，预设扰码可以包括但不局限于无线网络临时标识(RNTI)，该RNTI可以包括小区无线网络临时标识(C-RNTI)或新型的RNTI(即自定义的RNTI)。在该实施例中，使用预设扰码对时频资源区域及其相关时频资源区域的部分或全部业务数据进行解扰之后，若得到的业务数据为预先约定的业务数据，则表明解密成功，否则，解密失败。
2)使用预设扰码对时频资源区域及其相关时频资源区域的部分或全部业务数据进行解扰，并对解扰结果进行校验。
其中，预设扰码可以包括但不局限于RNTI，该RNTI可以包括C-RNTI或新型的RNTI。在该实施例中，在使用预设扰码对时频资源区域及其相关时频资源区域的部分或全部业务数据进行解扰之后，可以对解扰结果进行进一步校验，例如循环冗余校验(CRC)。若成功解扰且通过校验，则表明解密成功，否则，解密失败。
3)对时频资源区域及其相关时频资源区域的部分或全部业务数据进行校验。
在该实施例中，可以对时频资源区域及其相关时频资源区域的部分或全部业务数据进行CRC校验，若通过校验，则表明解密成功，否则，解密失败。
由此可见，该实施例可以通过多种方式对时频资源区域及其相关时频资源区域的部分或全部业务数据进行解密，实现方式灵活多样。
在步骤S105中，若解密成功，则确定第二业务数据抢占第一业务数据的时频资源。
其中，第二业务数据可以包括但不局限于URLLC数据。第二业务的优先级要高于第一业务，即第二业务相对于第一业务对及时性要求更高。
上述实施例，通过确定接收失败的第一业务数据对应的时频资源区域，并对时频资源区域及其相关时频资源区域的部分或全部业务数据进行解密，若解密成功，则可以确定第二业务数据抢占第一业务数据的时频资源，从而可以判断出业务数据间抢占时频资源的情况。
图2是本申请一示例性实施例示出的另一种抢占时频资源的确定方法的流程图，如图2所示，在上述步骤S103之后，该方法还可以包括：
在步骤S104中，若解密失败，则擦写掉预先缓存的时频资源区域的业务数据。
若解密失败，则确认第一业务数据接收失败，因此，可以擦写掉预先缓存的该时频资源区域的业务数据。
上述实施例，在对时频资源区域及其相关时频资源区域的部分或全部业务数据进行解密之后，若确认解密失败，则擦写掉预先缓存的时频资源区域的业务数据，从而可以节省UE 的缓存空间。
图3是本申请一示例性实施例示出的另一种抢占时频资源的确定方法的流程图，如图3所示，在上述步骤S103之前，该方法还可以包括：
在步骤S102中，接收基站发送的部分加密或全部加密后的第二业务数据。
在该实施例中，基站在向UE发送第一业务数据之后，可以向UE发送部分加密或全部加密后的第二业务数据，之所以发送部分加密或全部加密后的第二业务数据，是为了方便UE在对接收失败的第一业务数据对应的时频资源区域及其相关时频资源区域的部分或全部业务数据进行解密之后，可以判断出第二业务数据是否抢占第一业务数据的时频资源。
上述实施例，通过接收基站发送的部分加密或全部加密后的第二业务数据，为后续判断第二业务数据是否抢占第一业务数据的时频资源提供条件。
图4是本申请一示例性实施例示出的另一种抢占时频资源的确定方法的流程图，如图4所示，在上述步骤S103之前，该方法还可以包括：
在步骤S106中，接收基站发送的配置信息，并根据该配置信息获知相关时频资源区域。
在该实施例中，通过接收基站发送的配置信息，可以获知相关时频资源区域，从而可以对确定的时频资源区域及其相关时频资源区域的部分或全部业务数据进行解密。
另外，UE还可以通过其他方式获知相关时频资源区域，例如可以通过预先约定的方式获知相关时频资源区域。
上述实施例，通过接收基站发送的配置信息，并根据该配置信息获知相关时频资源区域，实现方式简单。
图5是本申请一示例性实施例示出的另一种抢占时频资源的确定方法的流程图，如图5所示，在上述步骤S105之后，该方法还可以包括：
在步骤S107中，保留抢占时频资源的第二业务数据，并向基站发送第一业务数据的HARQ反馈信息。
在该实施例中，由于抢占时频资源的第二业务数据是有用的数据，故抢占时频资源的第二业务数据不会被擦写掉，即UE保留抢占时频资源的第二业务数据。
在该实施例中，UE可以通过多种方式向基站发送第一业务数据的HARQ反馈信息，例如可以通过以下两种方式向基站发送HARQ反馈信息：
第一种方式，可以将被抢占时频资源的第一业务数据的接收成败状态设置为接收成功，并向基站发送HARQ反馈信息。
例如，可以将图1B中CBG4对应的eMBB数据的接收成败状态设置为接收成功，对于其他CBG对应的eMBB数据可以按照现有的方式进行反馈，即其他CBG对应的eMBB数据的接收成败状态均为接收成功，并向基站发送对应的HARQ反馈信息。
第二种方式，可以根据除被抢占时频资源的第一业务数据之外的第一数据接收成败状态，向基站发送HARQ反馈信息。
仍然以图1B为例进行描述，在图1B中，CBG4对应的eMBB数据为被抢占时频资源的第一业务数据，UE可以向基站发送CBG1、CBG2、CBG3、CBG5、CBG6、CBG7和CBG8的HARQ反馈信息。
基站在接收到UE发送的HARQ反馈信息后，可以据此判断出发送失败的eMBB数据，并重传发送失败的eMBB数据。
由此可见，该实施例可以通过多种方式向基站发送HARQ反馈信息，实现方式灵活多样。
上述实施例，通过保留抢占时频资源的第二业务数据，达到保留有用的第二业务数据的目的，从而使得第二业务数据可以正常传输，通过向基站发送第一业务数据的混合自动重传请求HARQ反馈信息，使得基站可以据此判断出发送失败的eMBB数据，从而为重传发送失败的eMBB数据提供条件。
图6是本申请一示例性实施例示出的又一种抢占时频资源的确定方法的流程图，该实施例从用基站侧进行描述，如图6所示，抢占时频资源的确定方法包括：
在步骤S601中，向UE发送第一业务数据。
其中，第一业务数据可以包括但不局限于eMBB数据。
在步骤S603中，对部分或全部第二业务数据进行加密，并向UE发送加密后的第二业务数据，以用于UE对接收失败的第一业务数据对应的时频资源区域及其相关时频资源区域的部分或全部业务数据进行解密来确定第二业务数据是否抢占第一业务数据的时频资源。
在该实施例中，对部分或全部第二业务数据进行加密可以包括但不局限于以下任一项：
1)使用预设扰码对部分或全部第二业务数据进行加扰。
在该实施例中，可以使用预设扰码对部分或全部第二业务数据进行加扰，其中，预设扰码可以包括但不局限于RNTI，该RNTI可以包括C-RNTI或新型的RNTI。加扰后的第二业务数据可以在时间或频率上周期性出现，如图1B所示，待解密的数据可以是加扰后的第二业务数据，从图1B可以看出，加扰后的第二业务数据在频率上周期性出现。
2)对部分或全部第二业务数据进行校验，并使用预设扰码对校验后的第二业务数据进行加扰。
在该实施例中，可以先对部分或全部第二业务数据进行CRC校验，然后使用预设扰码对校验后的第二业务数据进行加扰，其中，预设扰码可以包括但不局限于RNTI，该RNTI可以包括C-RNTI或新型的RNTI。这样，UE在接收到加扰后的第二业务数据后需要先解扰，然后进行校验，有利于提高确定第二业务数据抢占第一业务数据的时频资源的成功率。
3)对部分或全部第二业务数据进行校验。
在该实施例中，可以对部分或全部第二业务数据进行CRC校验。
由此可见，该实施例可以通过多种方式对部分或全部第二业务数据进行加密，实现方式灵活多样。
上述实施例，通过对部分或全部第二业务数据进行加密，并向UE发送加密后的第二业务数据，使得UE可以对接收失败的第一业务数据对应的时频资源区域及其相关时频资源区域的部分或全部业务数据进行解密来确定第二业务数据是否抢占第一业务数据的时频资源。
图7A是本申请一示例性实施例示出的再一种抢占时频资源的确定方法的流程图，如图7A所示，在上述步骤S603之前，该方法还可以包括：
在步骤S602中，确定第二业务数据属于预设调度类型且确定第二业务数据能够抢占第一业务数据的时频资源。
其中，预设调度类型可以包括免调度，第二业务数据可以包括但不局限于URLLC数据。
在该实施例中，基站在确定第二业务数据属于免调度且确定第二业务数据能够抢占第一业务数据的时频资源之后，可以对部分或全部第二业务数据进行加密。这样做的好处是，如果确定第二业务数据不能够抢占第一业务数据的时频资源，则可以不对第二业务数据进行加密，从而可以节省基站的计算资源。
在该实施例中，若调度第二业务数据所使用的时频资源区域位于调度第一业务数据所使用的时频资源区域内，则可以确定第二业务数据能够抢占第一业务数据的时频资源。
上述实施例，通过在确定第二业务数据属于免调度且确定第二业务数据能够抢占第一业务数据的时频资源之后，对部分或全部第二业务数据进行加密，有利于节省基站的计算资源。
图7B是本申请一示例性实施例示出的再一种抢占时频资源的确定方法的流程图，如图7B所示，在上述步骤S603之后，该方法还可以包括：
在步骤S604中，向UE发送配置信息，该配置信息用于通知UE用于解密的相关时频资源区域信息。
在该实施例中，通过向UE发送配置信息，使得UE可以根据该配置信息获知相关时频资源区域，从而可以对确定的时频资源区域及其相关时频资源区域的部分或全部业务数据进行解密。
上述实施例，通过向UE发送配置信息，使得UE可以根据该配置信息获知相关时频资源区域，从而可以对确定的时频资源区域及其相关时频资源区域的部分或全部业务数据进行解密。

确定解密模块82被配置为在接收读取模块81读取第一业务数据之后，若确定存在接收失败的第一业务数据，则确定接收失败的第一业务数据对应的时频资源区域，并对时频资源区域及其相关时频资源区域的部分或全部业务数据进行解密。
其中，业务数据对应的时频资源区域是指该业务数据所占用的时域资源和频域资源所对应的区域。某个时频资源区域的相关时频资源区域是指与该时频资源区域的时域和频域中的至少一项相关的时频资源区域，某个时频资源区域及其相关时频资源区域通常共用某些控制信息，这些控制信息可以包括但不局限于在时间和频率上周期出现的控制信息，例如同步 信号或参考信号等，相关时频资源区域可以包括但不局限于该时频资源区域的邻近时频资源区域。如图1B所示，接收失败的第一业务数据对应的时频资源区域是CBG4对应的时频资源区域，CBG4对应的时频资源区域的邻近时频资源区域为图1B中的时频资源区域X。包括但不限于时间和频率上周期出现的控制信息，如同步信号、参考信号等。
确定模块83被配置为在确定解密模块82对时频资源区域及其相关时频资源区域的部分或全部业务数据进行解密之后，若解密成功，则确定第二业务数据抢占第一业务数据的时频资源。
其中，第二业务数据可以包括但不局限于URLLC数据。第二业务的优先级要高于第一业务，即第二业务相对于第一业务对及时性要求更高。
上述实施例，通过确定接收失败的第一业务数据对应的时频资源区域，并对时频资源区域及其相关时频资源区域的部分或全部业务数据进行解密，若解密成功，则可以确定第二业务数据抢占第一业务数据的时频资源，从而可以判断出业务数据间抢占时频资源的情况。
图9A是根据一示例性实施例示出的另一种抢占时频资源的确定装置的框图，如图9A所示，在上述图8所示实施例的基础上，该装置还可以包括：接收模块84。
接收模块84被配置为在确定解密模块82对时频资源区域及其相关时频资源区域的部分或全部业务数据进行解密之前，接收基站发送的部分加密或全部加密后的第二业务数据。
在该实施例中，基站在向UE发送第一业务数据之后，可以向UE发送加密后的第二业务数据，之所以发送加密后的第二业务数据，是为了方便UE在对接收失败的第一业务数据对应的时频资源区域及其相关时频资源区域的部分或全部业务数据进行解密之后，可以判断出第二业务数据是否抢占第一业务数据的时频资源。
上述实施例，通过接收基站发送的加密后的第二业务数据，为后续判断第二业务数据是否抢占第一业务数据的时频资源提供条件。

保留发送模块85被配置为在确定模块83确定第二业务数据抢占第一业务数据的时频资源之后，保留抢占时频资源的第二业务数据，并向基站发送第一业务数据的混合自动重传请求HARQ反馈信息。
在该实施例中，由于抢占时频资源的第二业务数据是有用的数据，故抢占时频资源的 第二业务数据不会被擦写掉，即UE保留抢占时频资源的第二业务数据。

图9C是根据一示例性实施例示出的另一种抢占时频资源的确定装置的框图，如图9C所示，在上述图9B所示实施例的基础上，保留发送模块85可以包括：第一发送单元851或者第二发送单元852。
第一发送单元851被配置为将被抢占时频资源的第一业务数据的接收成败状态设置为接收成功，并向基站发送HARQ反馈信息。
例如，可以将图1B中CBG4对应的eMBB数据的接收成败状态设置为接收成功，对于其他CBG对应的eMBB数据可以按照现有的方式进行反馈，即其他CBG对应的eMBB数据的接收成败状态均为接收成功，并向基站发送对应的HARQ反馈信息。
第二发送单元852被配置为根据除被抢占时频资源的第一业务数据之外的第一数据接收成败状态，向基站发送HARQ反馈信息。
仍然以图1B为例进行描述，在图1B中，CBG4对应的eMBB数据为被抢占时频资源的第一业务数据，UE可以向基站发送CBG1、CBG2、CBG3、CBG5、CBG6、CBG7和CBG8的HARQ反馈信息。

上述实施例，通过对部分或全部第二业务数据进行加密，并向UE发送加密后的第二业务数据，使得UE可以对接收失败的第一业务数据对应的时频资源区域及其相关时频资源区域的部分或全部业务数据进行解密来确定第二业务数据是否抢占第一业务数据的时频资源。
图11A是根据一示例性实施例示出的再一种抢占时频资源的确定装置的框图，如图11A所示，在上述图10所示实施例的基础上，该装置还可以包括：确定模块130。

其中，预设调度类型可以包括免调度，第二业务数据可以包括但不局限于URLLC数 据。
在该实施例中，基站在确定第二业务数据属于免调度且确定第二业务数据能够抢占第一业务数据的时频资源之后，可以对部分或全部第二业务数据进行加密。这样做的好处是，如果确定第二业务数据不能够抢占第一业务数据的时频资源，则可以不对第二业务数据进行加密，从而可以节省基站的计算资源。
在该实施例中，若调度第二业务数据所使用的时频资源区域位于调度第一业务数据所使用的时频资源区域内，则可以确定第二业务数据能够抢占第一业务数据的时频资源。
上述实施例，通过在确定第二业务数据属于免调度且确定第二业务数据能够抢占第一业务数据的时频资源之后，对部分或全部第二业务数据进行加密，有利于节省基站的计算资源。
图11B是根据一示例性实施例示出的再一种抢占时频资源的确定装置的框图，如图11B所示，在上述图10所示实施例的基础上，该装置还可以包括：第二发送模块140。
第二发送模块140被配置为在加密发送模块120向UE发送加密后的第二业务数据之后，向UE发送配置信息，配置信息用于通知UE用于解密的相关时频资源区域信息。
在该实施例中，通过向UE发送配置信息，使得UE可以根据该配置信息获知相关时频资源区域，从而可以对确定的时频资源区域及其相关时频资源区域的部分或全部业务数据进行解密。
上述实施例，通过向UE发送配置信息，使得UE可以根据该配置信息获知相关时频资源区域，从而可以对确定的时频资源区域及其相关时频资源区域的部分或全部业务数据进行解密。
图11C是根据一示例性实施例示出的再一种抢占时频资源的确定装置的框图，如图11C所示，在上述图10所示实施例的基础上，加密发送模块120可以包括：加扰单元1201、校验加扰单元1202或者校验单元1203。
加扰单元1201被配置为使用预设扰码对部分或全部第二业务数据进行加扰。
在该实施例中，可以使用预设扰码对部分或全部第二业务数据进行加扰，其中，预设扰码可以包括但不局限于RNTI，该RNTI可以包括C-RNTI或新型的RNTI。加扰后的第二业务数据可以在时间或频率上周期性出现，如图1B所示，待解密的数据可以是加扰后的第二业务数据，从图1B可以看出，加扰后的第二业务数据在频率上周期性出现。
校验加扰单元1202被配置为对部分或全部第二业务数据进行校验，并使用预设扰码对校验后的第二业务数据进行加扰。
在该实施例中，可以先对部分或全部第二业务数据进行CRC校验，然后使用预设扰码对校验后的第二业务数据进行加扰，其中，预设扰码可以包括但不局限于RNTI，该RNTI可以包括C-RNTI或新型的RNTI。这样，UE在接收到加扰后的第二业务数据后需要先解扰，然后进行校验，有利于提高确定第二业务数据抢占第一业务数据的时频资源的成功率。
校验单元1203被配置为对部分或全部第二业务数据进行校验。
在该实施例中，可以对部分或全部第二业务数据进行CRC校验。
上述实施例，可以通过多种方式对部分或全部第二业务数据进行加密，实现方式灵活多样。
