Description

抢占时频资源的确定方法及装置和用户设备 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1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1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S102中，若确定存在接收失败的第一业务数据，则根据接收失败的第一业务数据所占用的时频资源，读取设定时段内和设定频率范围内的第二业务调度控制数据。
其中，第二业务可以包括但不局限于URLLC，调度控制数据可以包括但不局限于物理下行控制信道(PDCCH)，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。
其中，设定时段包括接收失败的第一业务数据所在资源单元对应的时段及其邻近时段， 或者接收失败的第一业务数据所在资源单元对应的时段。例如，UE以每个CBG为单位读取基站发送的eMBB数据，在确定存在图2A所示的接收失败的eMBB数据时，该设定时段包括图2A中的CBG4对应的时段。又例如，UE以两个CBG为单位读取基站发送的eMBB数据，在确定存在图2B所示的接收失败的eMBB数据(即CBG4的eMBB数据接收失败)时，该设定时段包括图2B中的CBG4对应的时段以及CBG4的邻近时段即CBG3对应的时段。
其中，设定频率范围为由接收失败的第一业务数据所占用的频率与预设频率区间宽度之差到接收失败的第一业务数据所占用的频率与预设频率区间宽度之和形成的频率区间，假设接收失败的第一业务数据所占用的频率为A，预设频率区间宽度为L，则设定频率范围为(A-L，A+L)。
在该实施例中，预设频率区间宽度可以包括第二业务数据占用的最大频率区间宽度。需要说明的是，第二业务数据占用的最大频率区间宽度是预设频率区间宽度的最小值，即预设频率区间宽度要大于或等于第二业务数据占用的最大频率区间宽度。
在步骤S103中，若读取到第二业务调度控制数据，且根据第二业务调度控制数据中携带的调度信息确定被调度的第二业务数据所占用的时频资源区域覆盖接收失败的第一业务数据所占用的时频资源区域，则确定第二业务数据抢占第一业务数据的时频资源。
其中，业务数据所占用的时频资源区域是指对应业务数据所占用的时域资源和频域资源所对应的区域。
在该实施例中，在读取设定时段内和设定频率范围内的第二业务调度控制数据例如URLLC PDCCH之后，若读取到URLLC PDCCH，且根据URLLC PDCCH中携带的调度信息确定被调度的URLLC数据所占用的时频资源区域部分覆盖或全部覆盖接收失败的eMBB数据所占用的时频资源区域，则可以确定URLLC数据抢占eMBB数据的时频资源。
上述实施例，通过根据接收失败的第一业务数据所占用的时频资源读取设定时段内和设定频率范围内的第二业务调度控制数据，并在读取到第二业务调度控制数据，且根据第二业务调度控制数据中携带的调度信息确定被调度的第二业务数据所占用的时频资源区域覆盖接收失败的第一业务数据所占用的时频资源区域时，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之后，该方法还可以包括：
在步骤S104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。
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2A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2A为例进行描述，在图2A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4是根据一示例性实施例示出的一种抢占时频资源的确定装置的框图，抢占时频资源的确定装置位于UE中，如图4所示，抢占时频资源的确定装置包括：接收读取模块41、确定读取模块42和确定模块43。
接收读取模块41被配置为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。
确定读取模块42被配置为在接收读取模块41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，则根据接收失败的第一业务数据所占用的时频资源，读取设定时段内和设定频率范围内的第二业务调度控制数据。
其中，第二业务可以包括但不局限于URLLC，调度控制数据可以包括但不局限于物理下行控制信道(PDCCH)，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。
其中，设定时段包括接收失败的第一业务数据所在资源单元对应的时段及其邻近时段，或者接收失败的第一业务数据所在资源单元对应的时段。例如，UE以每个CBG为单位读取基站发送的eMBB数据，在确定存在图2A所示的接收失败的eMBB数据时，该设定时段包括图2A中的CBG4对应的时段。又例如，UE以两个CBG为单位读取基站发送的eMBB数据，在确定存在图2B所示的接收失败的eMBB数据(即CBG4的eMBB数据接收失败)时，该设定时段包括图2B中的CBG4对应的时段以及CBG4的邻近时段即CBG3对应的时段。
其中，设定频率范围为由接收失败的第一业务数据所占用的频率与预设频率区间宽度之差到接收失败的第一业务数据所占用的频率与预设频率区间宽度之和形成的频率区间，假设接收失败的第一业务数据所占用的频率为A，预设频率区间宽度为L，则设定频率范围为(A-L，A+L)。
在该实施例中，预设频率区间宽度可以包括第二业务数据占用的最大频率区间宽度。需要说明的是，第二业务数据占用的最大频率区间宽度是预设频率区间宽度的最小值，即预设频率区间宽度要大于或等于第二业务数据占用的最大频率区间宽度。
确定模块43被配置为若确定读取模块42读取到第二业务调度控制数据，且根据第二业务调度控制数据中携带的调度信息确定被调度的第二业务数据所占用的时频资源区域覆盖接收失败的第一业务数据所占用的时频资源区域，则确定第二业务数据抢占第一业务数据的时频资源。
其中，确定模块43可以被配置为被调度的第二业务数据所占用的时频资源区域部分覆盖或全部覆盖接收失败的第一业务数据所占用的时频资源区域。
其中，业务数据所占用的时频资源区域是指对应业务数据所占用的时域资源和频域资源所对应的区域。
在该实施例中，在读取设定时段内和设定频率范围内的第二业务调度控制数据例如 URLLC PDCCH之后，若读取到URLLC PDCCH，且根据URLLC PDCCH中携带的调度信息确定被调度的URLLC数据所占用的时频资源区域部分覆盖或全部覆盖接收失败的eMBB数据所占用的时频资源区域，则可以确定URLLC数据抢占eMBB数据的时频资源。
上述实施例，通过根据接收失败的第一业务数据所占用的时频资源读取设定时段内和设定频率范围内的第二业务调度控制数据，并在读取到第二业务调度控制数据，且根据第二业务调度控制数据中携带的调度信息确定被调度的第二业务数据所占用的时频资源区域覆盖接收失败的第一业务数据所占用的时频资源区域时，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5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5所示，在上述图4所示实施例的基础上，该装置还可以包括：保留发送模块44。
保留发送模块44被配置为在确定模块43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。
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6所示，在上述图5所示实施例的基础上，保留发送模块44可以包括：第一发送单元441或者第二发送单元442。
第一发送单元441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。
第二发送单元442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。
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2A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2A为例进行描述，在图2A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。
上述实施例，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。
