Description

一种数据传输方法、网络设备、用户设备 技术领域
本发明涉及信息处理技术领域,尤其涉及一种数据传输方法、网络设备、用户设备、芯片、计算机可读存储介质、计算机程序产品以及计算机程序。
背景技术
随着人们对速率、延迟、高速移动性、能效的追求以及未来生活中业务的多样性、复杂性,为此3GPP国际标准组织开始研发5G。5G的主要应用场景为:增强移动超宽带(eMBB,Enhanced Mobile Broadband)、低时延高可靠通信(URLLC,Ultra-Reliable Low-Latency Communications)、大规模机器类通信(mMTC,massive Machine Type of Communication)。
在NR***中,存在动态调度(比如,通过下行控制信息(DCI,Downlink Control Information))和预配置资源的两种调度方式。对动态调度来说,一个DCI中仅可以对UE进行上行链路(UL,Uplink)调度,或者进行下行链路(DL,DownLink)调度,即仅指示一个方向的传输资源。UE在接收到DL调度后,还需要进行对应的上行资源的请求,由于需要再次向网络侧请求为终端分配UL资源,因此会带来较大的信令开销,并且造成传输时延。
发明内容
为解决上述技术问题,本发明实施例提供了一种数据传输方法、网络设备、用户设备、芯片、计算机可读存储介质、计算机程序产品以及计算机程序。
第一方面,提供了一种数据传输方法,所述方法包括:

第八方面,提供了一种用户设备,所述用户设备包括:
第四通信单元,接收网络设备发送的第一信息;其中,所述第一信息用于使得UE确定是否进行上行反馈;
第四处理单元,基于所述第一信息确定是否执行上行反馈。
第九方面,提供了一种网络设备,包括处理器和存储器。该存储器用于存储计算机程序,该处理器用于调用并运行该存储器中存储的计算机程序,执行上述第一方面、第二方面或其各实现方式中的方法。

第十四方面,提供了一种计算机程序,当其在计算机上运行时,使得计算机执行上述第一方面至第四方面中的任一方面或其各实现方式中的方法。
通过采用上述方案,能够在调度DL资源的时候同时发送用于UE确定配对的UL资源的指示信息,如此,减少了在调度DL资源之后,再次为UE分配UL资源所带来的信令开销较大的问题,并且降低了数据传输的时延,提升了***的处理效率。

下面将结合本申请实施例中的附图,对本申请实施例中的技术方案进行描述,显然,所描述的实施例是本申请一部分实施例,而不是全部的实施例。基于本申请中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都属于本申请保护的范围。

示例性的,本申请实施例应用的通信***100可以如图1-1所示。该通信***100可以包括网络设备110,网络设备110可以是与UE120(或称为通信终端、终端)通信的设备。网络设备110可以为特定的地理区域提供通信覆盖,并且可以与位于该覆盖区域内的UE进行通信。可选地,该网络设备110可以是GSM***或CDMA***中的网络设备(Base Transceiver Station,BTS),也可以是WCDMA***中的网络设备(NodeB,NB),还可以是LTE***中的演进型网络设备(Evolutional Node B,eNB或eNodeB),或者是云无线接入网络(Cloud Radio Access Network,CRAN)中的无线控制器,或者该网络设备可以为移动交换中心、中继站、接入点、车载设备、可穿戴设备、集线器、交换机、网桥、路由器、5G网络中的网络侧设备或者未来演进的公共陆地移动网络(Public Land Mobile Network,PLMN)中的网络设备等。

为了能够更加详尽地了解本发明实施例的特点与技术内容,下面结合附图对本发明实施例的实现进行详细阐述,所附附图仅供参考说明之用,并非用来限定本发明实施例。
本发明实施例提供了一种数据传输方法,如图2所示,包括:
步骤21:网络设备向用户设备UE发送下行信息;
其中,所述下行信息中包含:下行链路DL资源的调度信息,以及用于确定与所述DL资源配对的上行链路UL资源的指示信息。
本发明实施例还提供了一种数据传输方法,如图3所示,所述方法包括:
步骤31:UE接收网络设备发送的下行信息;其中,所述下行信息中包含:下行链路DL资源的调度信息,以及用于确定与所述DL资源配对的上行链路UL资源的指示信息。
也就是说,网络设备向UE发送的用于调度DL资源的信息中,同时包含了用于确定与DL配对的UL资源的指示信息。相应的,UE能够基于该下行信息同时确定接收调度的DL的资源的位置,以及发送与DL对应的UL的资源的位置。从而,能够减少使用另外的信令再通知UE所要采用的UL资源所带来的信令开销,并且减少时延。
上述下行信息可以由:下行控制信息(DCI,Downlink Control Information)和/或介质接入控制(MAC,Media Access Control)控制元素(CE,Control Element)携带。
本实施例中网络设备可以为接入网设备,比如基站。
下面结合多种示例对本实施例提供的方案进行详细说明:
示例1、
比如参见图4-1,可以包括:
1、网络设备通过DCI携带的下行信息调度DL传输,利用同一个DCI携带的下行信息为UE指示是否存在配对的UL资源,或者,为UE指示配对的UL资源标识,或者指示配对的UL资源。
具体的,所述下行信息中,DL资源的调度信息中可以包括以下至少之一:
DL资源配置信息;其中,可以包括有DL资源的时频资源、DL资源的标识等等。DL资源一种具体的示例可以为SPS资源,也可以用于指示动态调度的DL资源;
DL资源激活指示;可以包括有DL资源的时频资源和/或是否激活该DL资源;和/或,DL资源的标识和/或是否激活该标识所对应的DL资源的指示;比如,指示SPS资源激活;比如,指示SPS index M的资源激活;
DL资源标识,如指示SPS资源index。
对UL传输来说,用于确定与所述DL资源配对的上行链路UL资源的指示信息中,包括以下至少之一:
是否存在与所述DL资源配对的UL资源的指示;
与所述DL资源配对的UL资源是否激活的指示;
为UE调度的UL资源的信息;
UL资源激活指示;
与所述DL资源配对的UL资源的标识的指示;
所述DL资源的标识。
具体来说,是否存在配对的UL资源的指示信息,可以通过一个指示位来表征,比如,指示位中指示为1,代表存在,则UE在收到该动态调度的DL资源时,同时激活或使用配对的UL资源;否则,若指示为0,代表不存在UL资源配置信息。
与所述DL资源配对的UL资源是否激活的指示;与上一条不同在于,本指示默认UE侧可以存在配对的UL资源的情况下,通过一个指示位来指示UE是否激活配对的UL资源;比如,指示为1,代表激活或使用,0代表不使用。具体的,UE侧保存的DL和与之配对的UL资源的信息,可以是网络配置的,或预定义的,或UE自己确定的。
为UE调度的UL资源的信息,可以理解为网络设备为UE配置如指示动态调度的UL资源,其中可以包括有UL的时频资源,或者还可以为UL的时频资源以及UL资源的标识信息。
UL资源激活指示;仅指示UL资源激活,但是本指示并不具体指示激活哪个UL资源,可以包含有两种情况,当UE仅配置了一个UL资源的时候,只要接收到UL资源激活指示就可以确定激活的UL资源是哪一个;另一种情况就是,UE配置有多个UL资源,那么UE可以自身从多个UL资源中选取一个进行激活,选取可以为随机进行的,也可以为根据不同UL资源的信号质量进行选择,比如优选信号质量最好的UL资源等等。或者,还可以,UE根据该UL资源激活指示和与所述DL资源配对的UL资源的标识的指示,从多个UL资源中确定对应该UL资源index的上行资源被激活或使用。
与所述DL资源配对的UL资源的标识的指示;本指示中可以仅包含有UL资源的标识,比如指示的CG资源标识(index);
所述DL资源的标识;当仅配置本条指示的时候,可以理解为UE根据DL资源的标识选取与其匹配的UL资源作为配对的UL资源;该选择的方式可以为UE随意选择,也可以为根据预设的或者网络配置的DL资源与UL资源的关联关系进行选择。
前述下行信息中用于确定与所述DL资源配对的UL资源的指示信息可以包含上述一个或多个信息,比如,本示例由于并未预先为UE配置DL资源及其配对的UL资源,因此,网络设备可以向UE发送存在与DL资源配对的UL资源的指示的同时,再包含为UE调度的UL资源的信息。
又比如,网络设备可以默认UE已经预存了多个UL资源,或者配置UE多个UL资源(如Configured grant),那么可以仅发送UL资源激活指示,进而由UE来确定采用哪个UL资源作为与DL资源配对的UL资源;还可以为发送UL资源激活指示的同时,携带与所述DL资源配对的UL资源的标识的指示,如此可以使得UE确定激活UL资源并且能够确定所要激活的是哪个UL资源。
需要指出的是,前述是否存在与所述DL资源配对的UL资源的指示单独存在时,如果指示为存在配对的UL资源那么可以进一步确定对应的配对的UL资源;如果指示为不存在与所述DL资源配对的UL资源的时候,可以按照现有技术进行后续处理。另外,如果指示为不存在与DL资源配对的UL资源的时候,可以默认网络设备需要结合前述用于确定与所述DL资源配对的上行链路UL资源的指示信息中的其他信息为UE进行指示,比如为UE调度的UL资源的信息,或者与所述DL资源配对的UL资源的标识的指示等等。
需要说明的是,前述下行信息除了可以通过DCI携带,还可以通过MAC CE的方式指示给UE,但是由MAC CE携带的时候,其中除指示动态调度的UL资源的方式之外的其他方式,都适用MAC CE的指示方式。
2、UE接收到下行信息之后,根据下行信息确定其所调度的DL资源,以及确定与所述DL资源配对的上行链路UL资源。然后UE使用DL资源和配对的UL资源进行数据传输。
例如,UE根据DCI,获取PDSCH资源位置,在PDSCH对应的资源上获取网络需求:温度检测信令,指示UE执行温度检测,上报温度信息。UE根据配对的UL资源是否激活或使用的指示和/或CG index,确定配对的UL资源使用,且配对的UL资源为 CG资源,其标识为CG index2,UE检测问题,并利用对应的CG index2的资源,或最近的一个/N个/所有的CG index2的资源,进行检测到的温度信息的上报。
又例如,UE根据DCI,确定SPS index3的资源激活,根据RRC配置的SPS index3的资源位置,UE在对应的SPS资源上获取网络需求:温度检测信令,指示UE执行温度检测,上报温度信息。由于DCI中同时指示配对的UL资源是否激活或使用的指示和/或CG index,UE确定配对的UL资源使用,且配对的UL资源为CG资源,其标识为CG index2,UE检测问题,并利用对应的CG index2的资源,或最近的一个/N个/所有的CG index2的资源,进行检测到的温度信息的上报。
又例如,UE根据DCI,获取PDSCH资源位置,在PDSCH对应的资源上获取网络需求:温度检测信令,指示UE执行温度检测,上报温度信息。由于DCI中同时指示动态调度的UL资源,UE认为存在配对的上行资源和具体应该使用的UL资源。而后,UE根据该DCI中同时指示的动态调度的UL资源,进行检测到的温度信息的上报。
3、然后网络设备在PUCCH资源上,接收针对UE针对DL资源(grant)的上行反馈,比如可以为HARQ反馈;并且在与DL资源配对的UL资源(grant)(PUSCH)上接收UE上报的信息。
上述示例为UE直接根据网络设备发送的下行信息来确定与DL资源配对的UL资源,然后进行数据传输。
示例2、
与示例1不同在于,本示例中在网络设备发送下行信息之前,还可以为UE进行预配置,具体可以为所述网络设备向所述UE发送用于数据传输的参数配置信息;
其中,所述用于数据传输的参数配置信息中,包括以下至少之一:
为所述UE配置的至少一个DL资源;
为所述UE配置的至少一个UL资源。
也就是说,UE可以预先接收到网络设备为其配置的多个DL资源,以及多个UL资源。需要指出的是,这里UL资源与DL资源可以为配对存在的也可以为不配对存在的。
如果为配对存在的,那么所述用于数据传输的参数配置信息,还包括:所述至少一个DL资源、与所述至少一个UL资源之间的关联关系。其中,可以为一个DL资源与一个UL资源之间的关联关系,也就是一个DL资源与其配对的一个UL资源;当然,还可以为一个DL资源与多个UL资源之间的关联关系,也就是一个DL资源与其配对的多个UL资源。当然,还可以为一个UL资源与多个DL资源之间的关联关系,也就是一个UL资源与其配对的多个DL资源。
所述用于数据传输的参数配置信息,还包括:所述UE在组调度中归属的组;可以为UE所在的UE组标识。这样,网络设备可以采用组调度的方式对UE进行调度,比如,下行信息针对了一个UE组进行调度。
所述用于数据传输的参数配置由RRC或者广播消息携带。
在完成上述处理之后,可以采用示例1中提供的方案进行后续处理。
结合图4-2对本示例进行详细说明:
1、网络设备通过RRC向UE发送用于数据传输的参数配置信息,具体的可以包括以下至少之一:
UE在组调度中归属的组,具体的,指示组调度使用的RNTI,和/或,组调度的组标识。
为所述UE配置的至少一个DL资源;也就是为UE预配置的DL资源,具体的可以为预配置的DL时频资源,如SPS资源,及其相应的SPS index。
为所述UE配置的至少一个UL资源;也就是为UE预配置的UL资源,具体的可以为为UE预配置的UL时频资源,如CG资源,及其相应的CG index。
其中,UE在组调度中归属的组的信息,也可是预定义的,或者UE自行确定的。
其中,组调度使用的RNTI也可是预定义的。
2、UE接收用于数据传输的参数配置信息并进行保存。当可以采用组调度时,UE采用组调度的RNTI进行检测,或者UE可以同时采用组调度RNTI和针对该UE的RNTI进行检测。
结合步骤1、2,对于预配置的DL资源以及UL资源的配置,可以存在以下两种方式:
第一种,由UE进行配对保存,比如,步骤2中,UE接收到用于数据传输的参数配置信息之后,将其中包含的至少一个DL资源以及至少一个UL资源进行关联保存;其中可以为一个DL资源配对一个UL资源,当然也可以一个DL资源配对多个UL资源,也可以一个UL资源配对多个DL资源,由UE来进行处理。
第二种,参见图4-3,可以在步骤1中的用于数据传输的参数配置信息中还配置了所述至少一个DL资源、与所述至少一个UL资源之间的关联关系。然后,由UE进行保存。同样的,该关联关系可以为一个DL资源与一个UL之间的配对,也可以为一个DL资源与多个UL资源之间的配对,也可以一个UL资源配对多个DL资源之间的配对。
具体的,在专用RRC信令或广播中配置以下信息至少之一:UL资源及其标识,DL资源及其标识,UL资源和DL资源的linkage关系(如UL资源index和DL资源index的绑定关系)。在基站通过DCI进行UE specific调度或组调度时,如请求UE上报温度探测结果,在DCI中指示DL资源的index。UE在收到该DCI后,根据linkage关系,确定UL资源index和其对应的UL资源,并使用该UL资源进行数据传输,如传输温度探测结果。这样能够避免在DCI调度DL资源后,再通过DCI调度UL资源带来的控制信令的开销和时延。
3、网络设备通过下行信息调度DL传输。同时,利用同一个下行信息为所述UE指示配对的UL资源是否可用或激活,是否存在配对的UL资源,或者,配对的UL资源标识,或者指示配对的UL资源。
其中,下行信息中包含的具体内容以及其组合处理的方式可以如示例1所示,这里不再赘述。另外,下行信息可以由DCI携带,或者可以由MAC CE携带,当由MAC CE携带的时候,不包含其中的动态调度的UL资源。
另外,本示例中还可以存在与示例1中不同的组合情况,比如,由于本示例在步骤1、2中已经预配置了DL资源以及UL资源,并且预先已经由UE或者网络设备配置得到DL资源以及UL资源之间的关联关系。
因此,在本示例中,网络设备可以默认为UE存在有与DL配对的UL资源,那么在下行信息中可以仅指示配对的UL资源是否激活。又或者,仅携带DL资源的标识,那么UE可以根据关联关系就能够确定与DL资源配对的UL资源。又或者,仅携带UL资源的标识,那么UE可以根据关联关系就能够确定该UL资源使用/激活,和/或,与UL资源配对的DL资源。
4、UE接收到所述下行信息之后,可以根据所述下行信息,确定其所调度的DL资源,以及确定使用或激活的与DL资源配对的UL资源。并使用DL资源和配对的UL资源进行数据传输。这里还需要说明的是,如果根据下行信息确定不激活或者不适用配对的UL资源的时候,可以等待网络设备重新采用新的信令为UE进行UL资源的指示,本实施例不做详述。
5、网络设备在对应的PUCCH资源上,接收UE针对DL grant的HARQ反馈,并 且在配对的UL grant(PUSCH)上接收UE上报的信息。
示例3、关于UE是否进行上行反馈的指示以及处理方法,可以包括:
网络设备向UE发送第一信息;其中,所述第一信息用于使得UE确定是否进行上行反馈。
相应的,UE侧可以执行的处理可以包括:
接收网络设备发送的第一信息,其中,所述第一信息用于使得UE确定是否进行上行反馈;基于所述第一信息确定是否执行上行反馈。
其中,所述上行反馈可以为针对下行调度的HARQ反馈。
需要指出的是,不进行上行反馈可以为不做反馈,或者不做反馈的指示,可以为针对UE的,或UE组的,或HARQ进程的,或者业务类型的,或者当次调度的,或者特定时间的,或者特定LCH不进行上行反馈。
其中,所述第一信息,包括以下至少之一:
指示UE是否进行上行反馈的指示信息;也就是说,以UE为粒度,指示是否需要该UE进行上行反馈;或者说,对当次调度,指示是否进行进行上行反馈;
不进行上行反馈的UE类型;此时,可以为第一信息中包含至少一个UE类型指示信息,也就是由UE来进行判断,如果是第一信息中所指示的UE类型中的一个就可以不进行上行反馈,如果不是该UE类型可以进行上行反馈。
不进行上行反馈的业务类型;也就是可以为特定业务类型或业务类型列表,比如其中可以包含至少一个指定的业务,一旦UE当前执行的业务,或者为UE配置的业务,或当前激活的业务为业务类型列表中包含的一个业务的时候,就可以不进行上行反馈。
不进行上行反馈的UE组标识;也就是说,如果第一信息中包含有至少一个UE组标识,则UE组中的全部UE均不进行上行反馈;其中,UE归属的UE组标识ID可以为预配置或指示的。或者,UE组标识可以为预配置或指示的对应的组的RNTI。存在归属的UE组的UE,采用相应的组的RNTI进行检测;又或者是UE通过自己专用的RNTI和对应的组的RNTI来进行检测调度。
不进行上行反馈的UE标识;
不进行上行反馈的进程标识。
前述第一信息可以包含一个信息也可以包含有多个信息,比如,可以包含有指示UE是否进行上行反馈的指示信息,以及不进行上行反馈的UE标识、结合不进行上行反馈的业务类型;那么UE可以根据第一信息在确定不进行上行反馈的时候,进一步确定自身是否第一信息中所指示的不进行上行反馈的UE的标识(或UE的类型),如果是的话,基于不进行上行反馈的业务类型来判断当前自身处理的业务是否进行上行反馈。
当然,还可以存在其他更多的组合方式,只是本示例中不做穷举。
采用本示例,能够配置UE在满足一定条件时,不进行上行反馈,即不进行HARQ反馈,以减少PUCCH的开销。
另外,示例3可以与示例1或示例2结合使用,示例3也可以单独使用,当示例3与示例1或示例2结合使用的时候,可以为UE在确定是否进行上行反馈之后,采用示例1或示例2确定与DL资源配对的UL资源并进行后续处理。
本示例的一种处理方式如下所示:
1、网络设备向UE发送第一信息;其中,所述第一信息可以由DCI、MAC CE、RRC信令、广播信息至少之一携带。
具体的,所述第一信息具体的可以包括以下至少之一:
UE在组调度中归属的组,具体的,指示组调度使用的RNTI,组调度的组标识。
指示UE是否进行上行反馈的指示信息;具体的可以为HARQ less功能是否开启。 如开启,则UE或满足条件的UE可以不反馈HARQ-ACK,或者当次调度的UE可以不反馈HARQ-ACK;
不进行上行反馈的指示HARQ less的UE组标识。如指示组标识,该组UE可以不反馈HARQ-ACK
不进行上行反馈的UE类型。指示HARQ less的UE type标识。如指示UE type标识,该type的UE可以不反馈HARQ-ACK
不进行上行反馈的业务类型。比如,HARQ less的traffic type标识。如指示traffic type标识,承载该traffic type的UE,或对该traffic type的业务可以不反馈HARQ-ACK。
不进行上行反馈的UE标识。比如,指示HARQ less的UE标识。如指示UE标识,该UE可以不反馈HARQ-ACK。
不进行上行反馈的UE组标识。比如,指示HARQ less的UE组标识。如HARQ进程标识,该HARQ进程可以不反馈HARQ-ACK。
2、UE接收第一信息。
进而UE根据第一信息中网络为其配置的参数,确定自身是否满足不进行上行反馈的条件。也就是是否满足HARQ less执行的条件,并在满足条件时不进行HARQ反馈。
举例来说,第一信息为组标识(UE group id 1)和/或HARQ less功能开启,则若收到SPS调度或DCI指示的动态调度,且调度对象为该UE组标识的对象,则组内UE不进行HARQ-ack反馈。
又例如,第一信息为UE标识(UE id 1)和/或HARQ less功能开启,则若收到SPS调度或DCI指示的动态调度,且调度对象针对该UE标识1,则该UE不进行HARQ-ack反馈。
又例如,第一信息为不进行上行反馈的业务类型和/或指示UE不进行上行反馈的指示,即HARQ less功能开启;则若收到SPS调度或DCI指示的动态调度,则支持或承载该业务类型对应的业务的UE不进行HARQ-ack反馈。
本示例的又一种处理方式为:
1、网络设备通过RRC为UE发送用于数据传输的参数配置信息,如SPS资源,SPS index等。具体的说明与示例2中相同,这里不再赘述。
2、网络设备向所述UE分配动态调度的DL资源,或者激活配置的至少一个DL资源。也就是向UE通过调度的方式,分配动态调度的DL资源(dynamic grant for DL)或激活配置的预配置的DL资源(SPS for DL)。其中,激活配置的至少一个DL资源可以为,激活预先配置的至少一个DL资源中的一个,或者可以为激活预先配置的至少一个DL资源中的多个。
此外,基站通过DCI或MAC CE向UE第一信息;其中第一信息的具体说明与前述一种处理方式相同,这里不再赘述。
3、UE接收前述第一信息以及用于数据传输的参数配置信息,判断自身是否满足不进行上行反馈的条件,在满足条件时不进行上行反馈;比如,UE判断自身是否满足HARQ less执行的条件,并在满足条件时不进行HARQ反馈。
例如,第一信息为特定RNTI(特定组调度的RNTI),则归属于该组的UE,该UE收到由该RNTI调度的下行资源,则组内UE不进行HARQ-ack反馈。
又例如,第一信息为UE标识(UE id 1)和/或HARQ less功能开启,则若收到SPS调度或DCI指示的动态调度,且调度对象针对该UE id1,则该UE不进行HARQ-ack反馈。
又例如,第一信息为traffic type和/或HARQ less功能开启,则若收到SPS调度或DCI指示的动态调度,则支持或承载该traffic type业务的UE不进行HARQ-ack反馈。
在前述基础之上,所述第一信息,还包括以下至少之一:
对DL调度不进行上行反馈的时间段;
对DL调度不进行上行反馈的时间样式;
不进行上行反馈的逻辑信道的标识。
其中,对DL调度不进行上行反馈的时间段,可以理解为:不进行上行反馈的DL调度所在的下行时间,也就是这段下行时间内DL资源调度的内容不需要进行上行反馈;具体的可以为PDCCH所对应的下行时间段,或者可以为PDCCH调度的PDSCH对应的下行时间段。或者,还可以理解为,对DL调度不进行上行反馈的上行时间段,也就是说,在这段时间内,接收到DL调度但是如果其对应的上行反馈的时间在所述上行时间段内,则不进行上行反馈。或者,还可以理解为,对DL调度不进行上行反馈的上行时间段,也就是说,若对应DL调度的上行反馈在这段时间内,则不进行上行反馈。需要理解的是,这里的时间,可以为一个时间段(如从SFN1到SFN10),可以为一个时间点(如SFN1)。同样的,上行反馈的时间样式也可以理解为上两种维度,这里不再赘述。
举例来说,网络设备也就是基站指示UE不进行HARQ反馈的DL调度的时间或时间pattern,或者指示不进行HARQ反馈的逻辑信道;相应的,当UE在对应的时间或实际pattern收到DL调度时,或者确定DL调度中包含对应的逻辑信道的数据时,UE不对该DL调度的资源,进行上行的HARQ反馈,即不使用PUCCH反馈HARQ ACK/NACK。这样,就能够为是否进行上行反馈提供更大的灵活度。
图5为一种示例,其中网络设备也就是基站执行步骤1为UE发送第一信息。步骤2网络设备向UE发送DCI 1。然后UE执行步骤3判断是否对DCI1调度的DL资源进进行上行反馈,根据判断结果可以确定对DCI 1调度的DL资源进行上行反馈;又或者,接收DCI 2,通过判断确定不对其进行上行反馈。
最后,针对前述示例1、2、3,还可以包括以下处理:
UE向网络设备发送第二信息;其中,所述第二信息包括以下至少之一:UE类型、UE支持的业务类型、UE使用的业务类型,UE是否支持不进行上行反馈的能力,UE是否支持使用或激活配对的UL传输的能力。相应的,网络设备接收所述UE发送的第二信息。
一种示例中,在网络指示第一信息前,通过第一节点获知相关信息,如UE type,支持的traffic type,是否支持HARQ less的能力,确定是否指示第一信息给UE。第一节点可以为UE,核心网,工业网的中心控制节点等。从而,通过上报第二信息,辅助基站能够更好的配置和调度。
另一示例中,UE向网络设备上报第二信息,所述第二信息用于网络设备确定以下至少之一:
基于所述第二信息,确定是否为所述UE发送第一信息;
或者,基于所述第二信息,确定是否为所述UE生成所述下行信息;
或者,基于所述第二信息,确定是否为所述UE配置用于数据传输的参数配置信息。
其中,上报第二信息的时间可以为UE初始连接网络的时候,或者UE更新处理的时候,比如更换了新的业务类型等等。
可见,通过采用上述方案,就能够在调度DL资源的时候同时发送用于UE确定配对的UL资源的指示信息,如此,减少了在调度DL资源之后,再次为UE分配UL资源所带来的信令开销较大的问题,并且降低了数据传输的时延,提升了***的处理效率。
本发明实施例还提供一种数据传输方法,参见图6,可以包括:
步骤41:网络设备向UE发送第一信息;其中,所述第一信息用于使得UE确定是否进行上行反馈。
相应的,UE侧的一种数据传输方法,如图7所示,包括:
步骤51:接收网络设备发送的第一信息,其中,所述第一信息用于使得UE确定是否进行上行反馈;
步骤52:基于所述第一信息确定是否执行上行反馈。
其中,所述上行反馈可以为针对下行调度的HARQ反馈。
需要指出的是,不进行上行反馈可以为不做反馈,或者不做反馈的指示,可以为针对UE的,或UE组的,或HARQ进程的,或者业务类型的,或者当次调度的,或者特定时间的,或者特定LCH不进行上行反馈。
其中,所述第一信息,包括以下至少之一:
指示UE是否进行上行反馈的指示信息;也就是说,以UE为粒度,指示是否需要该UE进行上行反馈;或者说,对当次调度,指示是否进行进行上行反馈;
不进行上行反馈的UE类型;此时,可以为第一信息中包含至少一个UE类型指示信息,也就是由UE来进行判断,如果是第一信息中所指示的UE类型中的一个就可以不进行上行反馈,如果不是该UE类型可以进行上行反馈。
不进行上行反馈的业务类型;也就是可以为特定业务类型或业务类型列表,比如其中可以包含至少一个指定的业务,一旦UE当前执行的业务,或者为UE配置的业务,或当前激活的业务为业务类型列表中包含的一个业务的时候,就可以不进行上行反馈。
不进行上行反馈的UE组标识;也就是说,如果第一信息中包含有至少一个UE组标识,则UE组中的全部UE均不进行上行反馈;其中,UE归属的UE组标识ID可以为预配置或指示的。或者,UE组标识可以为预配置或指示的对应的组的RNTI。存在归属的UE组的UE,采用相应的组的RNTI进行检测;又或者是UE通过自己专用的RNTI和对应的组的RNTI来进行检测调度。
不进行上行反馈的UE标识;
不进行上行反馈的进程标识。
前述第一信息可以包含一个信息也可以包含有多个信息,比如,可以包含有指示UE是否进行上行反馈的指示信息,以及不进行上行反馈的UE标识、结合不进行上行反馈的业务类型;那么UE可以根据第一信息在确定不进行上行反馈的时候,进一步确定自身是否第一信息中所指示的不进行上行反馈的UE的标识(或UE的类型),如果是的话,基于不进行上行反馈的业务类型来判断当前自身处理的业务是否进行上行反馈。
当然,还可以存在其他更多的组合方式,只是本示例中不做穷举。
采用本实施例,能够配置UE在满足一定条件时,不进行上行反馈,即不进行HARQ反馈,以减少PUCCH的开销。
一种处理方式如下所示:
1、网络设备向UE发送第一信息;其中,所述第一信息可以由DCI、MAC CE、RRC信令、广播信息至少之一携带。
具体的,所述第一信息具体的可以包括以下至少之一:
UE在组调度中归属的组,具体的,指示组调度使用的RNTI,组调度的组标识。
指示UE是否进行上行反馈的指示信息;具体的可以为HARQ less功能是否开启。如开启,则UE或满足条件的UE可以不反馈HARQ-ACK,或者当次调度的UE可以不反馈HARQ-ACK;
不进行上行反馈的指示HARQ less的UE组标识。如指示组标识,该组UE可以不反馈HARQ-ACK
不进行上行反馈的UE类型。指示HARQ less的UE type标识。如指示UE type标识,该type的UE可以不反馈HARQ-ACK
不进行上行反馈的业务类型。比如,HARQ less的traffic type标识。如指示traffic type标识,承载该traffic type的UE,或对该traffic type的业务可以不反馈HARQ-ACK。
不进行上行反馈的UE标识。比如,指示HARQ less的UE标识。如指示UE标识,该UE可以不反馈HARQ-ACK。
不进行上行反馈的UE组标识。比如,指示HARQ less的UE组标识。如HARQ进程标识,该HARQ进程可以不反馈HARQ-ACK。
2、UE接收第一信息。
进而UE根据第一信息中网络为其配置的参数,确定自身是否满足不进行上行反馈的条件。也就是是否满足HARQ less执行的条件,并在满足条件时不进行HARQ反馈。
举例来说,第一信息为组标识(UE group id 1)和/或HARQ less功能开启,则若收到SPS调度或DCI指示的动态调度,且调度对象为该UE组标识的对象,则组内UE不进行HARQ-ack反馈。
又例如,第一信息为UE标识(UE id 1)和/或HARQ less功能开启,则若收到SPS调度或DCI指示的动态调度,且调度对象针对该UE标识1,则该UE不进行HARQ-ack反馈。
又例如,第一信息为不进行上行反馈的业务类型和/或指示UE不进行上行反馈的指示,即HARQ less功能开启;则若收到SPS调度或DCI指示的动态调度,则支持或承载该业务类型对应的业务的UE不进行HARQ-ack反馈。
又一种处理方式为:
1、网络设备通过RRC为UE发送用于数据传输的参数配置信息,如SPS资源,SPS index等。具体的说明与示例2中相同,这里不再赘述。
2、网络设备向所述UE分配动态调度的DL资源,或者激活配置的至少一个DL资源。也就是向UE通过调度的方式,分配动态调度的DL资源(dynamic grant for DL)或激活配置的预配置的DL资源(SPS for DL)。其中,激活配置的至少一个DL资源可以为,激活预先配置的至少一个DL资源中的一个,或者可以为激活预先配置的至少一个DL资源中的多个。
此外,基站通过DCI或MAC CE向UE第一信息;其中第一信息的具体说明与前述一种处理方式相同,这里不再赘述。
3、UE接收前述第一信息以及用于数据传输的参数配置信息,确定自身是否满足HARQ less执行的条件,并在满足条件时不进行HARQ反馈。
例如,第一信息为特定RNTI(特定组调度的RNTI),则归属于该组的UE,该UE收到由该RNTI调度的下行资源,则组内UE不进行HARQ-ack反馈。
又例如,第一信息为UE标识(UE id 1)和/或HARQ less功能开启,则若收到SPS调度或DCI指示的动态调度,且调度对象针对该UE id1,则该UE不进行HARQ-ack反馈。
又例如,第一信息为traffic type和/或HARQ less功能开启,则若收到SPS调度或DCI指示的动态调度,则支持或承载该traffic type业务的UE不进行HARQ-ack反馈。
在前述基础之上,所述第一信息,还包括以下至少之一:
对DL调度不进行上行反馈的时间段;
对DL调度不进行上行反馈的时间样式;
不进行上行反馈的逻辑信道的标识。
其中,对DL调度不进行上行反馈的时间段,可以理解为:不进行上行反馈的DL 调度所在的下行时间,也就是这段下行时间内DL资源调度的内容不需要进行上行反馈;具体的可以为PDCCH所对应的下行时间段,或者可以为PDCCH调度的PDSCH对应的下行时间段。或者,还可以理解为,对DL调度不进行上行反馈的上行时间段,也就是说,在这段时间内,接收到DL调度但是如果其对应的上行反馈的时间在所述上行时间段内,则不进行上行反馈。或者,还可以理解为,对DL调度不进行上行反馈的上行时间段,也就是说,若对应DL调度的上行反馈在这段时间内,则不进行上行反馈。需要理解的是,这里的时间,可以为一个时间段(如从SFN1到SFN10),可以为一个时间点(如SFN1)。同样的,上行反馈的时间样式也可以理解为上两种纬度,这里不再赘述。
举例来说,网络设备也就是基站指示UE不进行HARQ反馈的DL调度的时间或时间pattern,或者指示不进行HARQ反馈的逻辑信道;相应的,当UE在对应的时间或实际pattern收到DL调度时,或者确定DL调度中包含对应的逻辑信道的数据时,UE不对该DL调度的资源,进行上行的HARQ反馈,即不使用PUCCH反馈HARQ ACK/NACK。这样,就能够为是否进行上行反馈提供更大的灵活度。
最后,本实施例还还可以包括以下处理:
UE向网络设备发送第二信息;其中,所述第二信息包括以下至少之一:UE类型、UE支持的业务类型、UE使用的业务类型,UE是否支持不进行上行反馈的能力,UE是否支持使用或激活配对的UL传输的能力。相应的,网络设备接收所述UE发送的第二信息。
一种示例中,在网络指示第一信息前,通过第一节点获知相关信息,如UE type,支持的traffic type,是否支持HARQ less的能力,确定是否指示第一信息给UE。第一节点可以为UE,核心网,工业网的中心控制节点等。从而,通过上报第二信息,辅助基站能够更好的配置和调度。
另一示例中,UE向网络设备上报第二信息,所述第二信息用于网络设备确定以下至少之一:
基于所述第二信息,确定是否为所述UE发送第一信息;
或者,基于所述第二信息,确定是否为所述UE生成所述下行信息;
或者,基于所述第二信息,确定是否为所述UE配置用于数据传输的参数配置信息。
其中,上报第二信息的时间可以为UE初始连接网络的时候,或者UE更新处理的时候,比如更换了新的业务类型等等。
可见,通过采用上述方案,就能够控制终端是否进行上行反馈,如此,能够使得一部分业务或一部分终端不进行上行反馈,从而减少了信令开销较大的问题,并且降低了数据传输的时延,提升了***的处理效率。
本发明实施例提供了一种网络设备,如图8所示,包括:
第一通信单元61,向用户设备UE发送下行信息;
其中,所述下行信息中包含:下行链路DL资源的调度信息,以及用于确定与所述DL资源配对的上行链路UL资源的指示信息。
本发明实施例还提供了一种用户设备,如图9所示,包括:
第三通信单元71,接收网络设备发送的下行信息;其中,所述下行信息中包含:下行链路DL资源的调度信息,以及用于确定与所述DL资源配对的上行链路UL资源的指示信息。
也就是说,网络设备向UE发送的用于调度DL资源的信息中,同时包含了用于确定与DL配对的UL资源的指示信息。相应的,UE能够基于该下行信息同时确定接收调 度的DL的资源的位置,以及发送与DL对应的UL的资源的位置。从而,能够减少使用另外的信令再通知UE所要采用的UL资源所带来的信令开销,并且减少时延。
上述下行信息可以由:下行控制信息(DCI,Downlink Control Information)和/或介质接入控制(MAC,Media Access Control)控制元素(CE,Control Element)携带。
本实施例中网络设备可以为接入网设备,比如基站。
下面结合多种示例对本实施例提供的方案进行详细说明:
示例1、
网络设备的第一通信单元61通过DCI携带的下行信息调度DL传输,利用同一个DCI携带的下行信息为UE指示是否存在配对的UL资源,或者,为UE指示配对的UL资源标识,或者指示配对的UL资源。
具体的,所述下行信息中,DL资源的调度信息中可以包括以下至少之一:

为UE调度的UL资源的信息;
UL资源激活指示;
与所述DL资源配对的UL资源的标识的指示;
所述DL资源的标识。
用户设备(UE)还包括:第三处理单元72;其中,
UE的第三通信单元71接收到下行信息之后,第三处理单元72,根据下行信息确定其所调度的DL资源,以及确定与所述DL资源配对的上行链路UL资源。然后UE使用DL资源和配对的UL资源进行数据传输。
然后网络设备的第一通信单元61在PUCCH资源上,接收针对UE针对DL grant的上行反馈,比如可以为HARQ反馈;并且在与DL资源配对的UL grant(PUSCH)上接收UE上报的信息。
上述示例为UE直接根据网络设备发送的下行信息来确定与DL资源配对的UL资源,然后进行数据传输。
示例2、
与示例1不同在于,本示例中在网络设备发送下行信息之前,还可以为UE进行预配置,具体可以为所述网络设备的第一通信单元61,向所述UE发送用于数据传输的参数配置信息;
其中,所述用于数据传输的参数配置信息中,包括以下至少之一:
为所述UE配置的至少一个DL资源;
为所述UE配置的至少一个UL资源。
也就是说,UE可以预先接收到网络设备为其配置的多个DL资源,以及多个UL资源。需要指出的是,这里UL资源与DL资源可以为配对存在的也可以为不配对存在的。
如果为配对存在的,那么所述用于数据传输的参数配置信息,还包括:所述至少一个DL资源、与所述至少一个UL资源之间的关联关系。其中,可以为一个DL资源与一个UL资源之间的关联关系,也就是一个DL资源与其配对的一个UL资源;当然,还可以为一个DL资源与多个UL资源之间的关联关系,也就是一个DL资源与其配对的多个UL资源。当然,还可以为一个UL资源与多个DL资源之间的关联关系,也就是一个UL资源与其配对的多个DL资源。
所述用于数据传输的参数配置信息,还包括:所述UE在组调度中归属的组;可以为UE所在的UE组标识。这样,网络设备可以采用组调度的方式对UE进行调度,比如,下行信息针对了一个UE组进行调度。
所述用于数据传输的参数配置由RRC或者广播消息携带。
在完成上述处理之后,可以采用示例1中提供的方案进行后续处理。
示例3、关于UE是否进行上行反馈的指示以及处理方法,可以包括:
网络设备的第一通信单元61,向UE发送第一信息;其中,所述第一信息用于使得UE确定是否进行上行反馈。

需要指出的是,不进行上行反馈可以为不做反馈,或者不做反馈的指示,可以为针对UE的,或UE组的,或HARQ进程的,或者业务类型的,或者当次调度的,或者特定时间的,或者特定LCH不进行上行反馈。
其中,所述第一信息,包括以下至少之一:
指示UE是否进行上行反馈的指示信息;也就是说,以UE为粒度,指示是否需要该UE进行上行反馈;或者说,对当次调度,指示是否进行进行上行反馈;
不进行上行反馈的UE类型;此时,可以为第一信息中包含至少一个UE类型指示信息,也就是由UE来进行判断,如果是第一信息中所指示的UE类型中的一个就可以不进行上行反馈,如果不是该UE类型可以进行上行反馈。
不进行上行反馈的业务类型;也就是可以为特定业务类型或业务类型列表,比如其中可以包含至少一个指定的业务,一旦UE当前执行的业务,或者为UE配置的业务,或当前激活的业务为业务类型列表中包含的一个业务的时候,就可以不进行上行反馈。
不进行上行反馈的UE组标识;也就是说,如果第一信息中包含有至少一个UE组标识,则UE组中的全部UE均不进行上行反馈;其中,UE归属的UE组标识ID可以为预配置或指示的。或者,UE组标识可以为预配置或指示的对应的组的RNTI。存在归属的UE组的UE,采用相应的组的RNTI进行检测;又或者是UE通过自己专用的RNTI和对应的组的RNTI来进行检测调度。
不进行上行反馈的UE标识;
不进行上行反馈的进程标识。
前述第一信息可以包含一个信息也可以包含有多个信息,比如,可以包含有指示UE是否进行上行反馈的指示信息,以及不进行上行反馈的UE标识、结合不进行上行反馈的业务类型;那么UE可以根据第一信息在确定不进行上行反馈的时候,进一步确定自身是否第一信息中所指示的不进行上行反馈的UE的标识(或UE的类型),如果是的话,基于不进行上行反馈的业务类型来判断当前自身处理的业务是否进行上行反馈。
当然,还可以存在其他更多的组合方式,只是本示例中不做穷举。
采用本示例,能够配置UE在满足一定条件时,不进行上行反馈,即不进行HARQ 反馈,以减少PUCCH的开销。
另外,示例3可以与示例1或示例2结合使用,示例3也可以单独使用,当示例3与示例1或示例2结合使用的时候,可以为UE在确定是否进行上行反馈之后,采用示例1或示例2确定与DL资源配对的UL资源并进行后续处理。
本示例的又一种处理方式为:

网络设备的第一通信单元61向所述UE分配动态调度的DL资源,或者激活配置的至少一个DL资源。也就是向UE通过调度的方式,分配动态调度的DL资源(dynamic grant for DL)或激活配置的预配置的DL资源(SPS for DL)。其中,激活配置的至少一个DL资源可以为,激活预先配置的至少一个DL资源中的一个,或者可以为激活预先配置的至少一个DL资源中的多个。
此外,基站通过DCI或MAC CE向UE第一信息;其中第一信息的具体说明与前述一种处理方式相同,这里不再赘述。
UE的第三通信单元71,接收前述第一信息以及用于数据传输的参数配置信息,UE的第三处理单元72确定自身是否满足HARQ less执行的条件,并在满足条件时不进行HARQ反馈。
在前述基础之上,所述第一信息,还包括以下至少之一:
对DL调度不进行上行反馈的时间段;
对DL调度不进行上行反馈的时间样式;
不进行上行反馈的逻辑信道的标识。
其中,对DL调度不进行上行反馈的时间段,可以理解为:不进行上行反馈的DL调度所在的下行时间,也就是这段下行时间内DL资源调度的内容不需要进行上行反馈;具体的可以为PDCCH所对应的下行时间段,或者可以为PDCCH调度的PDSCH对应的下行时间段。或者,还可以理解为,对DL调度不进行上行反馈的上行时间段,也就是说,在这段时间内,接收到DL调度但是如果其对应的上行反馈的时间在所述上行时间段内,则不进行上行反馈。或者,还可以理解为,对DL调度不进行上行反馈的上行时间段,也就是说,若对应DL调度的上行反馈在这段时间内,则不进行上行反馈。需要理解的是,这里的时间,可以为一个时间段(如从SFN1到SFN10),可以为一个时间点(如SFN1)。同样的,上行反馈的时间样式也可以理解为上两种维度,这里不再赘述。
最后,针对前述示例1、2、3,还可以包括以下处理:
UE的第三通信单元71向网络设备发送第二信息;其中,所述第二信息包括以下至少之一:UE类型、UE支持的业务类型、UE使用的业务类型,UE是否支持不进行上行反馈的能力,UE是否支持使用或激活配对的UL传输的能力。相应的,网络设备接收所述UE发送的第二信息。
一种示例中,在网络指示第一信息前,通过第一节点获知相关信息,如UE type,支持的traffic type,是否支持HARQ less的能力,通过第一处理单元62确定是否指示第一信息给UE。第一节点可以为UE,核心网,工业网的中心控制节点等。从而,通过上报第二信息,辅助基站能够更好的配置和调度。
另一示例中,UE的第三通信单元71向网络设备上报第二信息,所述第二信息用于网络设备的第一处理单元62确定以下至少之一:
基于所述第二信息,确定是否为所述UE发送第一信息;
或者,基于所述第二信息,确定是否为所述UE生成所述下行信息;
或者,基于所述第二信息,确定是否为所述UE配置用于数据传输的参数配置信息。
其中,上报第二信息的时间可以为UE初始连接网络的时候,或者UE更新处理的时候,比如更换了新的业务类型等等。
可见,通过采用上述方案,就能够在调度DL资源的时候同时发送用于UE确定配对的UL资源的指示信息,如此,减少了在调度DL资源之后,再次为UE分配UL资源所带来的信令开销较大的问题,并且降低了数据传输的时延,提升了***的处理效率。
本发明实施例还提供一种网络设备,参见图10,可以包括:
第二通信单元81,向UE发送第一信息;其中,所述第一信息用于使得UE确定是否进行上行反馈。
相应的,本发明实施例还提供一种UE,如图11所示,包括:
第四通信单元91,接收网络设备发送的第一信息,其中,所述第一信息用于使得UE确定是否进行上行反馈;
第四处理单元92,基于所述第一信息确定是否执行上行反馈。
其中,所述上行反馈可以为针对下行调度的HARQ反馈。
需要指出的是,不进行上行反馈可以为不做反馈,或者不做反馈的指示,可以为针对UE的,或UE组的,或HARQ进程的,或者业务类型的,或者当次调度的,或者特定时间的,或者特定LCH不进行上行反馈。
其中,所述第一信息,包括以下至少之一:
指示UE是否进行上行反馈的指示信息;也就是说,以UE为粒度,指示是否需要该UE进行上行反馈;或者说,对当次调度,指示是否进行进行上行反馈;
不进行上行反馈的UE类型;此时,可以为第一信息中包含至少一个UE类型指示信息,也就是由UE来进行判断,如果是第一信息中所指示的UE类型中的一个就可以不进行上行反馈,如果不是该UE类型可以进行上行反馈。
不进行上行反馈的业务类型;也就是可以为特定业务类型或业务类型列表,比如其中可以包含至少一个指定的业务,一旦UE当前执行的业务,或者为UE配置的业务,或当前激活的业务为业务类型列表中包含的一个业务的时候,就可以不进行上行反馈。
不进行上行反馈的UE组标识;也就是说,如果第一信息中包含有至少一个UE组标识,则UE组中的全部UE均不进行上行反馈;其中,UE归属的UE组标识ID可以为预配置或指示的。或者,UE组标识可以为预配置或指示的对应的组的RNTI。存在归属的UE组的UE,采用相应的组的RNTI进行检测;又或者是UE通过自己专用的RNTI和对应的组的RNTI来进行检测调度。
不进行上行反馈的UE标识;
不进行上行反馈的进程标识。
前述第一信息可以包含一个信息也可以包含有多个信息,比如,可以包含有指示UE是否进行上行反馈的指示信息,以及不进行上行反馈的UE标识、结合不进行上行反馈的业务类型;那么UE可以根据第一信息在确定不进行上行反馈的时候,进一步确定自身是否第一信息中所指示的不进行上行反馈的UE的标识(或UE的类型),如果是的话,基于不进行上行反馈的业务类型来判断当前自身处理的业务是否进行上行反馈。
当然,还可以存在其他更多的组合方式,只是本示例中不做穷举。
采用本实施例,能够配置UE在满足一定条件时,不进行上行反馈,即不进行HARQ反馈,以减少PUCCH的开销。
可见,通过采用上述方案,就能够控制终端是否进行上行反馈,如此,能够使得一部分业务或一部分终端不进行上行反馈,从而减少了信令开销较大的问题,并且降低了 数据传输的时延,提升了***的处理效率。
