Description
本申请涉及移动通信技术领域,特别涉及一种提前终止方法、装置、设备及存储介质。
在LTE 4G***中,为了支持物联网业务提出了机器类通信(Machine Type Communication,MTC),窄带物联网(Narrow band Internet of thing,NB-IoT)两大技术。这两大技术主要针对的是低速率,高时延等场景。比如抄表,环境监测等场景。
相关技术中,NB-IoT目前最大只能支持几百k的速率,MTC目前最大只能支持几M的速率。但同时另外一方面,随着物联网业务的不断发展,比如视频监控,智能家居,可穿戴设备和工业传感监测等业务的普及。这些业务通常要求几十到100M的速率,同时对时延也有相对较高的要求,因此LTE中的MTC,NB-IoT技术很难满足要求。

本申请附加的方面和优点将在下面的描述中部分给出,部分将从下面的描述中变得明显,或通过本申请的实践了解到。
本申请上述的和/或附加的方面和优点从下面结合附图对实施例的描述中将变得明显和容易理解,其中:

下面详细描述本申请的实施例,所述实施例的示例在附图中示出,其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的,旨在用于解释本申请,而不能理解为对本申请的限制。
相关技术中,通过增强覆盖率来提高网速,针对需要进行覆盖增强的Redcap终端来说,由于测量不准确或者信道波动等因素,网络可能会终端配置过多的重复发送次数。在网络侧,有可能在终端还未发送完所有的重复传输时就已经成功地解调出了数据。那么此时网络可以给终端发送一个接收确认指示,指示终端停止当前的重复发送。这样的操作有利于终端节能。
然而,上述提到的early termination的工作机制是终端在发送数据的时候,同时监测搜索空间,通过监测对应的下行控制信息(Downlink Control Information,DCI)来确定是否有early termination的指示。
对于HD-FDD(Frequency Division Duplexing,频分双工)来说,终端在发送数据的时候无法进行物理下行控制信道(Physical Downlink Control Channel,PDCCH)的监测,而本申请实现了基于HD-FDD来支持early termination的方式。
为了描述的清楚,下面分别集中在HD-FDD终端设备和基站等网络侧描述本申请的提前终止方法。
下面首先集中在HD-FDD终端设备侧描述。
图1是根据本申请实施例提供的一种提前终止方法的流程图,其中,包括:
步骤101,根据被配置的时间单元监测携带下行控制信息DCI的PDCCH。
其中,DCI可以理解为PDCCH信道传输的与物理上下行共享信道相关的控制信息,这些DCI信息 包含了诸如RB资源分配信息、调制方式MCS、HARQ-ID等等若干相关内容。终端只有正确的解码到了DCI信息,才能正确的处理物理下行共享信道(Physical Downlink Shared Channe,PDSCH)数据或物理上行共享信道(Physical Uplink Shared Channel,PUSCH)数据。
本实施例中,通过DCI信息来携带有关提前终止的指示信息的发送。
在本实施例中,当HD-FDD被配置了提前终止功能后,网络还需要配置一些时间单元,在这一些时间单元上,终端停止数据发送,开始监测下行,监测是否有提前终止的指示。
在本实施例中,根据被配置的时间单元来检测携带下行控制信息DCI的PDCCH,由此,显然在没其他时间单元上进行有关数据的发送。
步骤102,根据DCI信息域的指示信息,终止HD-FDD终端设备进行重复传输。
在本实施例中,若是监测到DCI信息域的指示信息,则由于上述提到的,在本实施例中,通过DCI携带提前终止的指示信息,因此,终止HD-FDD终端设备进行重复传输,以实现对HD-FDD终端设备的节能。
需要说明的是,上述提到的DCI信息域可以理解为DCI码流中的某一个或多个比特位等。
当然,由于在本实施例中的时间单元是用来监测根据被配置的时间单元监测,以便于提前终止,因此,在本申请的一个实施例中,被配置的时间单元位于所配置的重复传输结束之前。
综上,本申请实施例的提前终止方法,根据被配置的时间单元监测携带下行控制信息DCI的PDCCH,根据DCI信息域的指示信息,终止HD-FDD终端设备进行重复传输。由此,在进行覆盖增强的场景下,实现了HD-FDD终端设备的节能。
在覆盖增强的场景中,为了实现HD-FDD终端设备的节能,在本申请的实施例中,根据被配置的时间单元监测携带下行控制信息DCI的PDCCH,根据DCI信息域的指示信息,终止HD-FDD终端设备进行重复传输。
而在实际应用中,可以通过不同的方式来配置时间单元,示例如下:
示例一:
在本示例中,根据预设协议来确定时间单元。
其中,预设协议可以理解为任意约定好的通信协议。
示例二:
在本示例中,接收基站等网络侧发送的携带时间单元的控制信令。从而,在本实施例中,由网络侧为终端设备配置下行的监测时间单元。
综上,本申请实施例的提前终止方法,可以根据场景需要灵活选择时间单元的配置方式,实用性较高。
在覆盖增强的场景中,为了实现HD-FDD终端设备的节能,在本申请的实施例中,根据被配置的时间单元监测携带下行控制信息DCI的PDCCH,根据DCI信息域的指示信息,终止HD-FDD终端设备进行重复传输,这里的时间单元在不同的应用场景中,对应于不同的时间区间,示例说明如下:
示例一:
在本实例中,根据被配置的时间单元监测携带下行控制信息DCI的PDCCH,为在被配置的至少一个固定时间单元达到时开始监测携带DCI的PDCCH,其中,该固定时间单元可以为任意一个或多个重复传输结束之前的时间单元,多个固定时间单元可以是间隔排列的,也可以是连续排列的,或者是二者的结合。
举例而言,参照图2(a),其中,图2(a)中的UL可以理解为上行的数据发送时间单元,DL可以理解为下行的监测时间单元。图2中包含了3个固定时间单元,间隔排列。
举例而言,如图2(b)所示,包含了3个固定时间单元,前2个时间单元连续,并与第三个固定时间单元间隔排列。
示例二:
在本示例中,在被配置的至少一个参考时间单元之后开始监测携带DCI的PDCCH,即在参考时间单元之后,监测功能被激活,开始监测携带DCI的PDCCH。在本实施例中,可以在参考时间单元之后的根据预先配置的部分监测时间单元监测携带DCI的PDCCH,也可以使用当前传输次数对应的参考时间单元之后的每个时间单元监测携带DCI的PDCCH。
在一些可能的示例中,参考时间单元与HD-FDD终端设备配置的重传次数相关,比如,将参考时间单元确定为重传次数传输了一半之后的时间单元,又比如,将参考时间单元确定为重传次数传输了三分之一之后的时间单元等。
举例而言,如图3所示,参考时间单元为总的传输次数大于一半的位置处,当达到参考位置时开始监测携带DCI的PDCCH,在图3中,后续的参考时间单元中预先设置了3个用于监测携带DCI的PDCCH的时间单元(图3中上行时间单元中的白色区域的时间单元)。
综上,本申请实施例的提前停止方法,根据场景需要灵活确定监测携带DCI的PDCCH的时间单元,提高了时间单元配置的灵活性。
基于上述实施例,终端设备在搜索空间监测PDCCH时,为了减少终端设备的盲检次数,终端设备可只监测特定的PDCCH。
在本申请的一个实施例中,根据被配置的时间单元监测携带目标DCI格式的PDCCH,即对于携带其他控制信息的PDCCH不再检测,仅仅检测携带目标DCI格式的PDCCH。
在本实施例中,在不同的应用场景中,目标DCI格式在不同的应用场景中不同,可以为任意一种未被固定为某种控制信息的格式,在一些可能的实施例中,目标DCI格式包括:上行调度准许UL grant DCI format。
参照图4,在本实施例中,在大量的PDCCH中,终端设备仅仅需要监测携带上行调度准许UL grant DCI format格式的PDCCH。
综上,本申请实施例的提前终止方法,根据被配置的时间单元监测携带目标DCI格式的PDCCH,减少了终端设备的盲检次数,进一步降低了终端设备的耗能。
下面集中在网络侧描述本申请实施例的提前终止方法。
图5是根据本申请另一个实施例的提前终止方法的流程图,如图5所示,该方法包括:
步骤501,为HD-FDD终端设备配置提前终止功能。
在本实施例中,为了保证在增强覆盖场景下,HD-FDD终端设备可以实现提前终止,为HD-FDD终端设备配置提前终止功能,比如,向HD-FDD终端设备发送提前终止的控制信令等。
步骤502,通过下行控制信息DCI指示HD-FDD终端设备提前终止重复传输。
在本实施例中,通过下行控制信息DCI指示HD-FDD终端设备提前终止重复传输,即扩展了DCI的指示内容,使得DCI可以用于指示终端设备提前终止重复传输。
综上,本申请实施例的提前终止方法,网络侧为HD-FDD终端设备配置所述提前终止功能,进而,通过下行控制信息DCI指示所述HD-FDD终端设备提前终止重复传输。由此,实现了在重传场景下的,HD-FDD终端设备可以实现提前终止以实现节能。
在实际执行中,网络侧可以采用不同的方式来通过下行控制信息DCI指示HD-FDD终端设备提前终止重复传输。
在本发明的一个实施例中,网络侧为HD-FDD终端设备配置用于监测DCI的时间单元,以便于HD-FDD终端设备基于时间单元监测监测携带下行控制信息DCI的PDCCH。这里的时间单元在不同的应用场景中,对应于不同的时间区间,示例说明如下:
示例一:
在本实例中,根据被配置的时间单元监测携带下行控制信息DCI的PDCCH,为在被配置的至少一个固定时间单元达到时开始监测携带DCI的PDCCH,其中,该固定时间单元可以为任意一个或多个重 复传输结束之前的时间单元,多个固定时间单元可以是间隔排列的,也可以是连续排列的,或者是二者的结合。
示例二:
在本示例中,在被配置的至少一个参考时间单元之后开始监测携带DCI的PDCCH,即在参考时间单元之后,监测功能被激活,开始监测携带DCI的PDCCH。在本实施例中,可以在参考时间单元之后的根据预先配置的部分监测时间单元监测携带DCI的PDCCH,也可以使用当前传输次数对应的参考时间单元之后的每个时间单元监测携带DCI的PDCCH。
在一些可能的示例中,参考时间单元与HD-FDD终端设备配置的重传次数相关,比如,将参考时间单元确定为重传次数传输了一半之后的时间单元,又比如,将参考时间单元确定为重传次数传输了三分之一之后的时间单元等。
综上,本申请实施例的提前终止方法,网络侧通过时间单元的方式来实现对HD-FDD终端设备提前终止重复传输的指示,实现了HD-FDD终端在覆盖增强场景下,可以提前终止以实现节能。
基于上述实施例,终端设备在搜索空间监测PDCCH时,为了减少终端设备的盲检次数,终端设备可只监测特定的PDCCH。
在本申请的一个实施例中,网络侧通过目标DCI格式指示HD-FDD终端设备提前终止重复传输,从而终端设备对于携带其他控制信息的PDCCH不再检测,仅仅检测携带目标DCI格式的PDCCH。
在本实施例中,在不同的应用场景中,目标DCI格式在不同的应用场景中不同,可以为任意一种未被固定为某种控制信息的格式,在一些可能的实施例中,目标DCI格式包括:上行调度准许UL grant DCI format。
综上,本申请实施例的提前终止方法,网络侧通过目标DCI格式指示HD-FDD终端设备提前终止重复传输,从而终端设备根据被配置的时间单元监测携带目标DCI格式的PDCCH,减少了终端设备的盲检次数,进一步降低了终端设备的耗能。
基于上述实施例,为了灵活满足不同的应用场景,网络侧为HD-FDD终端设备配置提前终止功能的方式可以灵活多变。
在一些可能的示例中,网络侧根据应用场景确定不禁止HD-FDD终端设备重复传输的提前终止功能,且在可配置的情况下为HD-FDD终端设备配置提前终止功能,由此,满足了HD-FDD终端设备可以根据场景需要灵活的选择是否可以进行提前终止功能的实施。
举例而言,在有些应用场景下,HD-FDD终端设备对能量的消耗比较敏感,因此,为了实现节能,由于HD-FDD终端设备重复传输的提前终止功能是不被禁止的,因此,当前情况属于可配置的情况,为HD-FDD终端设备配置提前终止功能。
在一些可能的示例中,网络侧根据应用场景确定禁止HD-FDD终端设备重复传输的提前终止功能。
举例而言,HD-FDD终端设备在发送比较重要的数据,为了保证数据的发送效率,需要保证每个时间单元都用于数据的发送,因此,网络侧根据应用场景确定禁止HD-FDD终端设备重复传输的提前终止功能。
综上,本申请实施例的提前终止方法,HD-FDD终端设备重复传输的提前终止功能,可以由网络侧灵活的选择是否禁止,满足不同场景的需要。

监测模块610,用于根据被配置的时间单元监测携带下行控制信息DCI的PDCCH;
终止模块620,用于根据DCI信息域的指示信息,终止HD-FDD终端设备进行重复传输。
