Description

调整信息传输的方法、基站及用户设备 技术领域
本公开涉及通信技术领域,尤其涉及一种调整信息传输的方法、基站及用户设备。
背景技术
5G NR(New Radio)可以在3.3GHz到24GHz的高频区间部署,因此5G NR系统中每个载波频率范围可能会比4G LTE(Long Term Evoluttion,长期演进)系统中的每个载波频率范围大很多。在5G网络中,单频带band的带宽会接近1GHz,单载波的带宽水平在80MHz~400MHz之间。出于5G网络UE(User Equipment,用户设备)节能等方面的考虑,可以将一个单载波划分为多个BWP(Band Width Part,带宽片段)。基站可以在一个或多个BWP上调度UE。
以基站当前在一个BWP如BWP1上调度UE为例,鉴于当前待传输业务量的变化或UE功耗等方面原因,基站需要调整调度UE的时频资源范围。比如,为了节能,将较宽带宽如40MHz的BWP1,调整为较窄带宽如20MHz的BWP2。
上述调整BWP的做法是解激活(Deactivate)当前BWP1,再激活(activate)BWP2。上述解激活/激活过程中,由于重新配置BWP2的传输控制信息,需要大量控制信令,一般通过上层消息如RRC(Radio Resource Control,无线资源控制)消息实现。
在此过程中,基站发出用于指示UE执行解激活和激活的预设RRC消息后,由于RRC消息向物理层映射、发送给UE,UE在应用层对消息进行验证、再映射到数据层等过程需要花费时间,会形成一个约数十毫秒的模糊期。在上述模糊期,基站无法确定UE什么时候完成预设RRC消息的接收和解析。若UE还没有成功切换到BWP2,基站已经取消在BWP1上调度UE并开始在BWP2调度UE,很可能导致传输丢失。或者,目标UE已经成功切换到BWP2,基站却还在BWP1上调度UE,也会导致传输丢失,影响5G网络设备的用户体验。

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。
本公开涉及的执行主体包括:基站和用户设备(User Equipment,UE),其中,基站可以是设置有大规模天线阵列的基站、子基站等。用户设备UE可以是用户终端、用户节点、移动终端或平板电脑等。在具体实现过程中,基站和用户设备各自独立,同时又相互联系,共同实现本公开提供的技术方案。
本公开提供的调整信息传输的应用场景为:基站调度UE的过程中,通过上层消息向目标UE发送BWP切换信息,告知目标UE解激活(Deactivate)当前BWP,然后再激活(Activate)一个新的BWP的方法实现BWP的转换。
基于上述应用场景,本公开提供了一种调整信息传输的方法,可以避免基站和目标UE在模糊期内传输信息导致传输丢失,如图1所示的一种因基站过早在第一BWP上取消对目标UE的调度、导致传输丢失的示意图。
本公开中,每个BWP中设置有控制资源集合CORESET(Control Resource Set,控制资源集合),如图1所示。CORESET中承载有目标UE的DCI(Downlink Control Information,下行控制信息),上述目标UE的下行控制信息包括:目标UE的调度控制信息、参考信号配置等信息。
参见图2根据一示例性实施例示出的一种调整信息传输的方法流程图,应用于基站中,所述方法可以包括以下步骤:
在步骤11中,通过上层消息向目标用户设备发送带宽片断BWP切换信息,所述BWP切换信息用于指示所述目标用户设备将当前承载信息传输的第一BWP切换为第二BWP;
本公开中,BWP切换信息包括:解激活当前BWP即第一BWP的解激活控制信息和激活第二BWP的激活控制信息。其中,上述激活控制信息包括:授权信息、传输配置信息等。
本公开实施例中,由于解激活第一BWP、再激活第二BWP需要大量控制信令,因此,需要通过上层消息向目标UE发送BWP切换信息。其中,上述上层消息可以是BWP切换信息在RRC(Radio Resource Control,无线资源控制)层被配置成的RRC信令;也可以是BWP切换信息在MAC(Medium Access Control,媒介访问控制)层被配置成的MAC CE(Control Element,控制单元)信令。
本公开中,关于触发基站向目标UE发送BWP切换信息的时机,可以是基站根据当前第一BWP的待传输业务量或者功耗需求自主决定为目标UE切换BWP;也可以是基站响应目标UE的请求,被动决定为目标UE切换BWP,本公开对此不做限制。
在步骤12中,监听所述目标用户设备的预设上行反馈信息,所述预设上行反馈信息用于表明所述目标用户设备已接收和/或解析所述BWP切换信息;
本公开中,上述步骤12的实施可以包括以下两种情况:
第一种情况,在t1时刻之后,基站在第一BWP上监听所述目标UE的预设上行反馈信息。
参见图3根据一示例性实施例示出的另一种调整信息传输的方法流程图,上述步骤12可以包括:
在步骤121中,在发送所述BWP切换信息之后,继续在所述第一BWP上调度所述目标用户设备;
参照图4-1根据一示例性实施例示出的一种调整信息传输的应用场景示意图。假设基站通过RRC信令向目标UE下发BWP切换信息的时刻为t1,由于RRC消息映射到物理层(Physical Layer)、传输给目标UE、通过目标UE的信息验证、再解析数据等过程需要花费时间,导致目标UE并不会立即从第一BWP切换到第二BWP上工作。假设上述过程需要花费的时间是50ms,本公开实施例中,在t1+50ms的时间范围 内,基站可以在第一BWP继续调度目标UE,进行下行传输和上行传输。
在步骤122中,接收所述目标用户设备通过所述第一BWP发送的上行信息;
在t1时刻之后,基站在第一BWP上继续调度目标UE,确保基站可以在第一BWP上持续接收目标UE发送的上行信息。上述上行信息可以包括:继续传输的上行数据;UCI(Uplink Control Information,上行控制信息),如下行数据传输的HARQ(Hybrid Automatic Repeat reQuest,混合自动重传请求)反馈信息,包括ACK/NACK信息;表示所述BWP切换信息接收和/或解析状态的转换反馈信息。
其中,上述转换反馈信息可以包括:
成功接收消息,用于告知基站已接收到的所述BWP切换信息;
解析失败消息,用于告知基站所述BWP切换信息解析失败;
解析成功消息,用于告知基站已成功解析所述BWP切换信息;
配置完成消息,用于告知基站已成功解析所述BWP切换信息并根据所述BWP切换信息完成对所述第二BWP的传输配置。
在步骤123中,从所述上行信息中监听预设上行反馈信息;
在t1时刻之后、基站在第一BWP上接收目标UE的上行信息的同时,还对该上行信息进行监听,以判断该上行信息中是否包括预设上行反馈信息。其中,该预设上行反馈信息可以包括以下任意一项:
成功接收消息,用于表明目标UE已经收到所述BWP切换信息;
解析成功消息,用于表明目标UE已成功解析所述BWP切换信息;
配置完成消息,用于表明目标UE已成功解析所述BWP切换信息,并根据所述BWP切换信息完成对第二BWP的传输配置。
第二种情况,在t1时刻之后,基站也可以同时在第一BWP和第二BWP上监听所述目标UE的预设上行反馈信息。
参见图5根据一示例性实施例示出的另一种调整信息传输的方法流程图,在图3所示实施例的基础上,上述步骤12还可以包括:
在步骤12-1中,在发送所述BWP切换信息之后,开始在所述第二BWP上调度所述目标用户设备;
在本公开一实施例中,基站可以从t1时刻,开始在第二BWP上调度目标UE,时刻准备接收目标UE通过第二BWP发送的上行信息,参见图6-1、6-2根据一示例性实施例示出的另一种调整信息传输的应用场景示意图。
本公开实施例中,基站可以在第一BWP、第二BWP上都为目标UE分配时频 资源,且在第二BWP上同时传输发送给目标UE下行数据。使得目标UE无轮当前是工作在第一BWP上还是工作在第二BWP上,都可以与基站之间进行信息传输,有效避免了信息传输丢失,提高了信息传输的可靠性。
在本公开另一实施例中,基站也可以从t1时刻的预设间隔时长之后,比如,从图6-3所述的t10时刻,假设t10=t1+1ms,开始在第二BWP上调度目标UE。其中,上述预设间隔时长,可以是基站根据先验信息确定的时长,如1ms。基站根据历史经验值,确定在上述预设间隔时长内目标UE无法完成上述BWP切换过程,如图6-3所示。本公开实施例,在确保信息传输可靠性的基础上,还可以节约传输资源。
在步骤12-2中,监听所述目标用户设备通过所述第二BWP发送的上行信息。
本公开实施例中,基站可以同时在第二BWP上监听目标UE发送的任何信息。一旦接收到目标UE通过第二BWP发送的上行信息,基站即可确定目标UE已完成对第二BWP的配置,可以放心在第一BWP上取消调度目标UE。
其中,上述目标UE通过第二BWP发送的上行信息可以包括以下至少一项:
第二BWP中参考信号的测量信息,如CQI反馈信息;
下行数据传输的HARQ反馈信息即ACK/NACK信息,包括:第一BWP承载的下行数据传输的HARQ反馈信息,和/或,第二BWP承载的下行数据传输的HARQ反馈信息。
表示所述BWP切换信息已成功接收和/或解析的预设上行反馈信息。
在步骤13中,若接收到所述预设上行反馈信息,停止在所述第一BWP上调度所述目标用户设备。
根据基站接收的预设上行反馈信息的不同,上述步骤13的具体实施方式也不同:
对应上述第一种情况,上述步骤13具体为:若基站在所述第一BWP上监听到目标UE发送的成功接收消息和/或配合完成消息,则可以确定目标UE已经具备激活第二BWP条件,或者说,确定目标UE已经激活第二BWP,可以停止在所述第一BWP上调度目标UE;可以包括以下至少四种实施方式:
方式一、若接收到目标UE发送的所述成功接收消息,开始在第二BWP上调度目标UE,并经过第一预设等待时长之后,停止在第一BWP上调度目标UE。
本公开实施例中,考虑到目标UE在接收到BWP切换信息之后,解析该信息以及根据BWP切换信息中的激活控制信息完成第二BWP的调度控制信息配置等过程,还需要花费一定的时间,因此,基站在接收到上述接收成功消息后,开始在第二 BWP上调度目标UE,并经过第一预设等待预设时长后,再停止在第一BWP上调度目标UE。其中,上述预设等待时长可以是基站根据历史经验确定的时长,如一个传输时间间隔TTI。
如图4-1所示,以基站调度目标UE时,时域上的基本信息传输单元为一个TTI(Transmission Time Interval,时间间隔)为例,假设基站在t2时刻接收到物理层发送的接收成功消息,则基站从t2时刻开始在第二BWP上调度目标UE,并在间隔一个TTI之后,停止在第一BWP上调度目标UE。
上述图4-1中,第一预设等待时长为t2与t3之间的间隔时长Δt1,即一个TTI的时长。
方式二、基站在接收到上述解析成功消息后,经过第二预设等待时长之后,停止在第一BWP上调度目标UE,开始在第二BWP上调度目标UE。
与上述方式一类似,若基站接收到目标UE通过第一BWP发送的解析成功消息,说明目标UE已经成功解析上述解激活控制信息和激活控制信息,但目标UE根据上述信息执行解激活和激活操作还需要一定的时间,尤其是配置第二BWP的调度控制信息需要花费时间,因此,基站在接收到上述解析成功消息后,经过第二预设等待时长后,再在第一BWP上取消调度目标UE。可以预知的是,上述第二预设等待时长小于上述第一预设等待时长。
如图4-2所示,假设基站在t2时刻接收到上层如RRC层发送的解析成功消息,可以在等待当前调度的TTI传输完成后,即t3时刻,停止在第一BWP上调度目标UE,并开始在第二BWP上调度目标UE。
可见,图4-2中第二预设等待时长即t2与t3之间的间隔时长Δt2,小于上述图4-1所示的第一预设等待时长,即图4-1所示的t2与t3之间的间隔时长Δt1即一个TTI的时长。
方式三、基站在接收到上述配置完成消息后,停止在第一BWP上调度目标UE,开始在第二BWP上调度目标UE。
若基站接收到目标UE发送的配置完成消息,可以确定目标UE在发送该消息之前已经做好了激活第二BWP的准备,上述消息传输所需时间足以满足目标UE执行一个解激活和激活的开关量,因此,基站在接收到上述配置完成消息后,可以停止在第一BWP上调度目标UE,开始在第二BWP上调度目标UE。
此种情况下,基站在接收到所述预设上行反馈信息之前,保持在所述第一BWP上调度所述目标UE,确保目标UE与基站之间信息传输不会中断,有效避免因BWP 切换导致信息传输丢失。
方式四,若接收到目标UE通过第二BWP发送的上行信息,停止在第一BWP上调度目标UE。
适用于上述第二种情况,当基站在同时调度第一BWP和第二BWP时,首先接收到了目标UE通过第二BWP发送的上行信息,则确定目标UE已成功激活第二BWP,因此,可以停止调度第一BWP。
对应上述第二种情况,上述步骤13具体为:若基站首先在所述第二BWP上监听到目标UE的上行信息,可以停止在所述第一BWP上调度目标UE。
若基站首先在所述第一BWP上监听到目标UE的预设上行反馈信息,可以按照上述方式一至方式三停止在所述第一BWP上调度目标UE,如图6-1、6-2所示。本公开实施例,可以进一步提高目标UE在进行BWP切换过程中信息传输的可靠性。
另外,在本公开另一实施例中,基站还可以对下行数据传输的HARQ反馈信息的传输方式进行配置。
参见图7根据一示例性实施例示出的另一种调整信息传输的方法流程图,在图2所示实施例的基础上,在步骤11之前,所述方法还可以包括:
在步骤10中,向目标用户设备发送预设HARQ反馈配置信息,所述预设HARQ反馈配置信息用于指示所述目标用户设备将所述第一BWP承载的下行数据传输的HARQ反馈信息,通过切换后的BWP发送给所述基站。
本公开另一实施例中,基站可以在发送上述BWP切换信息时即在t1时刻向目标UE发送预设HARQ反馈配置信息,告知目标UE在当前BWP上接收到下行数据传输的HARQ反馈信息可以通过切换后的BWP发送给基站。
本公开实施例中,基站可以将上述预设HARQ反馈配置信息通过广播信令、上层信令或物理层的PDCCH(Physical Downlink Control Channel,物理下行控制信道)信令,下发给目标UE。其中,所述上层信令可以是RRC信令、MAC CE信令。
采用此种方式,目标UE不必等到针对所有已调度下行数据传输都发送了HARQ反馈信息之后,再执行BWP切换。若最后一个数据传输完成时,最后一个下行数据传输的HARQ反馈信息还未通过第一BWP发送,也可以执行BWP切换,并根据上述预设HARQ反馈配置信息的规定,将第一BWP上最后一个下行数据传输的HARQ反馈信息,通过切换后的第二BWP发送给基站,不会导致下行数据传输的HARQ反馈信息丢失,若上述HARQ反馈信息为NACK信息,则基站可以在第二BWP上重传数据,提高信息传输的可靠性。
综上,采用本公开提供的调整信息传输的方法,基站采用上层消息向目标UE发送BWP切换消息后,通过监听预设上行反馈信息,可以明确确定目标UE完成BWP切换的状态,从而在接收到上述预设上行反馈信息后,取消在第一BWP上调度目标UE,开始或者保持在第二BWP上调度目标UE,有效避免基站通过上层消息指示用户设备切换BWP时,因无法确定目标UE对BWP切换消息的接收和解析状态而过早或过晚地停止在第一BWP上调度目标UE、造成信息传输丢失,确保目标UE在信息传输过程中切换BWP不会丢失信息传输,有效提高了BWP切换过程中信息传输的可靠性。
相应的,本公开提供了一种调整信息传输的方法,应用于用户设备中,参照图8根据一示例性实施例示出的一种调整信息传输的方法流程图,所述方法可以包括以下步骤:
在步骤21中,接收并解析基站发送的带宽片断BWP切换信息;
与上述步骤11相对应,目标UE在当前工作的BWP即第一BWP接收并解析基站发送的BWP切换信息。
在步骤22中,向所述基站发送预设上行反馈信息;
根据目标UE接收和解析上述BWP切换信息的状态,向基站发送用于表明已接收和/或成功解析上述BWP切换信息的预设反馈信息,与上述步骤12向对应。
本公开一实施例中,目标UE可以通过第一BWP向基站发送预设上行反馈信息。
可以在以下三种时机,触发目标UE发送预设上行反馈信息:
第一种时机,在接收到BWP切换信息后,如T1时刻,向基站发送接收成功消息,以告知基站已接收到BWP切换信息。
示例性的,上述T1时刻可以是图4-1、图6-1、图6-3所示的t2时刻。
第二种时机,目标UE接收并成功解析BWP切换信息后,如T2时刻,向基站发送解析成功消息,以告知基站已成功解析出第二BWP的激活控制信息。
第三种时机,目标UE成功解析出第二BWP的激活控制信息,并根据该激活控制信息完成对第二BWP的调度控制信息配置后,如T3时刻,向基站发送配置完成消息,以告知基站即将激活第二BWP。
若上述解析成功消息和配置完成消息属于上层响应(response)消息,如RRC response消息,示例性的,上述T2、T3时刻是图4-2、图6-2所示的t2时刻。
可知,预设上行反馈的触发时机不同,发送的上行反馈信息也不同。可以预见 的是,T1时刻早于T2时刻,T2时刻早于T3时刻。
对于不同时刻发送的上行反馈信息,基站可以决定在不同时机停止在第一BWP上调度目标UE,参见上述步骤13不同实施方式的描述。
在本公开另一实施例中,上述预设上行反馈信息也可以是目标UE激活第二BWP之后,在第二BWP上发送的任何上行信息。
在步骤23中,根据所述BWP切换信息,将当前承载信息传输的第一BWP切换为第二BWP。
本公开中,目标UE在接收、解析BWP切换信息之后,可以在不同时机切换BWP,即进行解激活第一BWP并激活第二BWP的操作。参照图9根据一示例性实施例示出的另一种调整信息传输的方法流程图,上述步骤23可以包括:
在步骤231中,在成功解析所述BWP切换信息后,确定所述第一BWP上当前是否存在正在调度的数据传输;
参见上述图4-1、图4-2和图6-1~图6-3所示的应用场景示意图,目标UE在接收、解析上述BWP切换信息以及根据该BWP切换信息进行传输配置时,基站继续在第一BWP上调度目标UE。目标UE在完成上述操作时,可以判断当前是否有正在调度的上行数据传输和/或下行数据传输。
在步骤232中,若存在所述正在调度的数据传输,在完成剩余数据传输之后,将第一BWP切换为所述第二BWP。
其中,所述剩余数据传输可以包括:剩余下行数据传输、剩余上行数据传输。上述各示意图中,t3时刻也可以理解为目标UE切花BWP的时刻。
本公开实施例中,为避免输出传输丢失或不必要的重传,目标UE可以在当前正在调度的数据传输完成后,再进行BWP切换。
本公开一实施例中,对于预设上行反馈信息发送时刻即t2时刻,若存在剩余下行数据传输,目标UE可以根据当前的HARQ反馈传输配置信息,确定BWP的切换时机。
参见图10根据一示例性实施例示出的一种调整信息传输的方法流程图,上述步骤231可以包括:
在步骤2321中,确定第一BWP的HARQ反馈传输配置信息;
本公开实施例中,目标UE对下行数据传输的HARQ反馈信息的发送方式可以是协议预设的固定方式,也可以是可配置的即根据基站发送的HARQ反馈传输配置信息适时配置的。
本公开中,关于对第一BWP承载下行数据传输的HARQ反馈传输配置可以包括以下两种配置方式:
第一种配置方式:第一BWP承载的下行数据传输的HARQ反馈信息,通过第一BWP发送给基站。
则上述步骤232为:在完成剩余数据传输并且发送完所述剩余下行数据传输的HARQ反馈信息之后,将第一BWP切换为所述第二BWP。此处的剩余数据传输包括:第一BWP承载的上行剩余传输和下行剩余数据传输。其中,上行剩余传输包括:上行剩余数据传输和上行控制信息传输。该上行控制信息传输至少包括:最后一个下行数据传输的HARQ反馈信息传输。
第二种配置方式:第一BWP承载的下行数据传输的HARQ反馈信息,可以通过切换后的BWP发送给基站。
针对第二种配置方式的预设HARQ反馈传输配置信息,可以是:指示所述目标用户设备将所述第一BWP承载的下行数据传输的HARQ反馈信息,通过切换后的BWP发送给所述基站。
对应上述第二配置方式,目标UE可以在步骤21之前获取上述预设HARQ反馈传输配置信息,参见上述步骤10。
在本公开另一实施例中,上述预设HARQ反馈传输配置信息也可以是包含于上述BWP切换信息中发送给目标UE。相应的,目标UE在解析BWP切换信息时获取到,并据此确定切换BWP的时机。
针对上述第二种配置方式,上述步骤232可以具体为:
在步骤2322中,若所述HARQ反馈传输配置信息为预设HARQ反馈传输配置信息,在完成所述剩余数据传输之后且在发送所述剩余下行数据传输的HARQ反馈信息之前,将第一BWP切换为所述第二BWP。
本公开实施例中,目标UE无需等待所述剩余下行数据传输的HARQ反馈信息传输完成,即可将第一BWP切换为所述第二BWP。对于基站同时调度第一BWP和第二BWP的情况,可以有效节约无效传输资源。
相应的,对于上述第二种情况,在基站首先接收到目标UE通过第二BWP发送的HARQ反馈信息的情况下,有可能接收到的是第一BWP上最后一个下行数据传输的HARQ反馈信息,如上所述。
可见,采用本公开提供的调整信息传输的方法,用户设备在准备切换BWP之间,首先向基站发送预设上行反馈信息,该预设上行反馈信息用于告知基站目标UE 已经接收和/或解析BWP切换信息,使得基站根据上述预设上行反馈信息可以明确目标UE当BWP切换信息的处理状态,从而确定在合适的时机即确定目标UE已激活第二BWP的情况下,取消在第一BWP上调度目标UE,确保基站和目标UE之间的信息传输不会因BWP切换而丢失,有效提供了信息传输的可靠性。
对于前述的各方法实施例,为了简单描述,故将其都表述为一系列的动作组合,但是本领域技术人员应该知悉,本公开并不受所描述的动作顺序的限制,因为依据本公开,某些步骤可以采用其他顺序或者同时进行。
