实施例1
本发明实施例提供一种反馈信息的发送方法,从终端设备侧(即反馈信息的发送侧)进行说明。图2是本发明实施例的反馈信息的发送方法的一示意图,如图2所示,该方法包括:
步骤201,终端设备确定混合自动重传请求(HARQ)反馈信息;
步骤202,所述终端设备根据接收到的指向同一时隙且同一PUCCH资源的多个DCI中的一个DCI(可以是任意一个DCI,例如是最后一个DCI),确定发送所述HARQ反馈信息的PUCCH资源;以及
步骤203,所述终端设备使用确定的所述PUCCH资源发送所述HARQ反馈信息。
值得注意的是,以上附图2仅对本发明实施例进行了示意性说明,但本发明不限于此。例如可以适当地调整各个步骤之间的执行顺序,此外还可以增加其他的一些步骤或者减少其中的某些步骤。本领域的技术人员可以根据上述内容进行适当地变型,而不仅限于上述附图2的记载。
由此,由于确定某一PUCCH资源时所依据的DCI指向同一时隙且同一PUCCH资源,不同业务(例如eMBB和URLLC)的PUCCH资源将被分开;这样,不同业务(例如URLLC与eMBB)的PUCCH资源能够被相互独立地确定,能够满足某一些场景(例如URLLC)在进行HARQ反馈时高可靠低时延的要求。
在一个实施例中,所述多个DCI可以先对同一个物理下行控制信道(PDCCH,Physical Downlink Control CHannel)检测机会索引的不同服务小区索引进行升序排列,再对不同PDCCH检测机会索引进行升序排列。在一个时隙中,终端设备可能检测到网络设备发送的一个或多个DCI,关于DCI和PDCCH以及物理下行共享信道(PDSCH,Physical Downlink Shared CHannel)的具体内容可以参考相关技术。
图3是本发明实施例的网络设备和终端设备通信的一示例图,如图3所示,网络设备(例如gNB)可以向终端设备(例如UE)发送多个数据信息,例如通过多个PDSCH承载;针对这些数据信息,UE可以向gNB反馈HARQ反馈信息(HARQ-ACK码书), 例如通过PUCCH承载。gNB还可以向UE发送多个DCI,通过PDCCH承载。
例如,如图3所示,PDCCH 1(承载有DCI 1)用于指示PDSCH 1,同理,PDCCH2(承载有DCI 2)用于指示PDSCH 2,PDCCH 3(承载有DCI 3)用于指示PDSCH3;而这三个PDSCH相对应的HARQ反馈信息都可以通过PUCCH在一个HARQ-ACK码书中发送。
在一个实施例中,所述同一PUCCH资源至少根据PUCCH资源集合的标识以及PUCCH资源的指示值确定。例如,所述PUCCH资源集合的标识为PUCCH配置信息PUCCH-config中的参数PUCCH-ResourceSetId的值,所述PUCCH资源的指示值为DCI格式1_0或DCI格式1_1中PUCCH资源指示域的值Δ
PRI;此外,在此基础上,PUCCH资源还可以根据PDSCH到HARQ反馈之间的时隙偏移K
1,时隙偏移K
0等参数确定。但本发明不限于此,例如在PUCCH资源集合的标识以及PUCCH资源的指示值的基础上,并不限于K
0和K
1,还可以使用其他参数或者包括更多的参数。
以下将通过半静态HARQ-ACK码书和动态HARQ-ACK码书,对本发明实施例进行进一步说明。
在一个实施例中,所述HARQ反馈信息形成半静态HARQ-ACK码书。
图4是本发明实施例的反馈信息的发送方法的另一示意图,从发送侧和接收侧进行说明。如图4所示,该方法包括:
步骤401,终端设备确定半静态HARQ-ACK码书包含的时隙范围和/或所对应的PDSCH的类型。
在本实施例中,候选PDSCH接收或半静态调度(SPS,Semi-Persistent Scheduling)PDSCH释放的监测时间窗可以小于预定值,该预定值例如是标准中定义的值。例如,需要监测的与激活的上行部分带宽(BWP,Bandwidth Part)相关联的PDSCH与HARQ反馈之间的时隙偏移K
1的集合的大小被减小。
例如,若为高优先级业务(例如URLLC)确定独立于低优先级业务(例如eMBB)的HARQ-ACK码书为半静态的,在确定包含M
A,C个候选PDSCH接收或SPS PDSCH释放的集合时,为减小高优先级用户设备反馈ACK/NACK(A/N)的时延,可以减小候选PDSCH接收或SPS PDSCH释放的监测时间窗。
例如,当K
1是由DCI格式1_0提供时,可以将与高优先级业务对应的DCI格式1_0中的集合{1,2,3,4,5,6,7,8}变小,例如缩小为{1,2};再例如,当K
1是由高层参 数‘dl-DataToUL-ACK’提供时,可以将与高优先级业务对应的该高层参数中K
1的集合设置为{1,2}。
由此,通过减小所述候选PDSCH接收或SPS PDSCH释放的监测时间窗,能够减小高优先级业务(例如URLLC业务)的反馈时延。
在本实施例中,所述HARQ反馈信息可以根据PDSCH的类型不同而被分别发送。即,第一业务的所述HARQ反馈信息承载第一类型的PDSCH的反馈信息比特,具有与所述第一业务不同优先级的第二业务的所述HARQ反馈信息承载第二类型的PDSCH的反馈信息比特。
例如,为减小高优先级业务与低优先级业务HARQ-ACK码书之间的冗余,在各自码书中可以区分type A PDSCH与type B PDSCH。例如:高优先级业务的码书仅承载type B PDSCH的HARQ-ACK信息比特,而低优先级业务的码书仅承载type A PDSCH的HARQ-ACK信息比特。
由此,根据PDSCH的类型不同而分别发送HARQ反馈信息,能够减小不同业务(例如高优先级业务与低优先级业务)HARQ-ACK码书之间的冗余。
如图4所示,该方法还可以包括:
步骤402,终端设备确定包含一个或多个候选PDSCH接收或SPS PDSCH释放的集合。
例如,可以执行3GPP TS 38.213中第9.1.2.1节中的第一段伪代码,确定包含M
A,C个候选PDSCH接收或SPS PDSCH释放的集合,这些候选的PDSCH有机会在时隙n发送相应的HARQ反馈信息。
在本实施例中,终端设备还可以根据处理能力参数N
3,调整候选PDSCH接收或者SPS PDSCH释放的集合。关于处理能力参数N
3,可以参考后面的实施例,还可以参考相关技术。
如图4所示,该方法还可以包括:
步骤403,终端设备接收网络设备发送的一个或多个DCI;
例如,终端设备可以在一个时隙中检测到一个或多个DCI。值得注意的是,步骤403并不一定在步骤402之后执行,也可以在步骤402或步骤401之前执行,或者与步骤402、401并行地执行。
步骤404,终端设备确定半静态HARQ-ACK码书;
例如,终端设备可以执行3GPP TS 38.213中第9.1.2.1节中的第二段伪代码,确定半静态HARQ-ACK码书中的O
ACK个HARQ反馈信息比特。
步骤405,终端设备确定发送半静态HARQ-ACK码书的PUCCH资源;
例如,终端设备可以基于在所有检测到的DCI格式1_0或DCI格式1_1中、域‘PDSCH-to-HARQ_feedback timing indicator’指向同一个时隙、且同一个PUCCH资源来发送携带HARQ反馈信息的PUCCH的一个DCI格式1_0或DCI格式1_1中的PUCCH资源指示域,确定发送HARQ-ACK码书的PUCCH资源。其中,检测到的多个DCI格式可以先对同一个PDCCH检测机会索引的不同服务小区索引进行升序排列,再对不同PDCCH监测机会索引进行升序排列。
例如,UE共检测到5个DCI,分别为DCI 1、DCI 2、DCI 3、DCI 4和DCI 5,其中DCI 1、DCI 3和DCI 4为DCI格式1_0,DCI 2、和DCI 5为DCI格式1_1,这5个DCI的‘PDSCH-to-HARQ_feedback timing indicator’域均指向同一时隙且同一PUCCH资源,则UE根据其中一个DCI(例如DCI 5)中的PUCCH资源指示域,确定发送HARQ-ACK码书的PUCCH资源。
如图4所示,该方法还可以包括:
步骤406,终端设备在上述确定的PUCCH资源上发送半静态HARQ-ACK码书。
值得注意的是,以上附图4仅对本发明实施例进行了示意性说明,但本发明不限于此。例如可以适当地调整各个步骤之间的执行顺序,此外还可以增加其他的一些步骤或者减少其中的某些步骤。本领域的技术人员可以根据上述内容进行适当地变型,而不仅限于上述附图4的记载。
由此,在确定PUCCH资源时,通过指向同一个时隙且同一个PUCCH资源的DCI,PUCCH资源能够被相互独立地确定;此外,通过减小监测时间窗和/或根据PDSCH的类型发送HARQ反馈,半静态HARQ-ACK码书能够被相互独立地确定,能够满足某一些场景(例如URLLC)在进行HARQ反馈时高可靠低时延的要求。
在另一个实施例中,所述HARQ反馈信息形成动态码书。
图5是本发明实施例的反馈信息的发送方法的另一示意图,从发送侧和接收侧进行说明。如图5所示,该方法包括:
步骤501,终端设备确定用于调度PDSCH接收或SPS PDSCH释放的DCI的PDCCH检测机会。
在本实施例中,可以根据PDSCH与HARQ反馈之间的时隙偏移K
1、PDSCH时域资源分配的时隙偏移K
0、PUCCH资源集合的标识以及PUCCH资源的指示值Δ
PRI,使得所述PDSCH接收或所述SPS PDSCH释放的HARQ反馈信息在同一时隙且同一PUCCH资源上被发送。
例如,可以基于3GPP TS 38.213中第10.1节,确定调度PDSCH接收或SPS PDSCH释放的DCI格式1_0或DCI格式1_1的PDCCH监测机会,并基于以下信息,使得UE在同一个时隙、且同一个PUCCH资源上发送上述PDSCH接收或SPS PDSCH释放的HARQ-ACK信息比特:
-PDSCH到HARQ反馈之间的时隙偏移K
1,其中在时隙n上发送携带与PDSCH接收或SPS PDSCH释放相对应的HARQ反馈信息的PUCCH;
-时隙偏移K
0,其由调度PDSCH接收或SPS PDSCH释放的PDCCH DCI格式1_0或DCI格式1_1中的时域资源分配的域指示,或由高层参数‘pdsch-AggregationFactor’提供;
-PUCCH资源集合的ID,即‘PUCCH-config’中高层参数‘PUCCH-ResourceSetId’的值;
-PUCCH资源指示值Δ
PRI,即相应DCI格式1_0或DCI格式1_1中PUCCH资源指示(PUCCH resource indicator,PRI)域的值。
值得注意的是,以上参数仅为本发明的例子,但本发明不限于此。例如在PUCCH资源集合的标识以及PUCCH资源的指示值的基础上,并不限于K
0和K
1,还可以使用其他参数或者包括更多的参数。
如图5所示,该方法还可以包括:
步骤502,所述终端设备根据处理能力参数N
3调整所述PDCCH检测机会。
例如,根据UE的处理能力N
3,判断上述步骤501确定的PDCCH监测机会的集合中是否包含了在UE处理范围之外的PDCCH,如果有,则从上述集合中去掉超出UE处理范围的PDCCH。
在本实施例中,在所述终端设备在一个时隙内检测到第一DCI指示了携带相应HARQ反馈信息的PUCCH发送的第一个资源,并且在同一时隙内再检测到第二DCI指示了携带相应HARQ反馈信息的PUCCH发送的第二个资源的情况下,如果包含所述第二DCI的PDCCH接收时间不早于所述PUCCH发送的第一个资源的起始符号 N
3个符号,则所述终端设备确定在所述时隙内的PUCCH资源上不复用与所述第二DCI相应的HARQ反馈信息,或者所述终端设备不期望在所述时隙内的PUCCH资源上复用与所述第二DCI相应的HARQ反馈信息。
例如,如果UE在一个时隙内检测到第一个DCI格式1_0或DCI格式1_1指示了携带相应HARQ反馈信息的PUCCH发送的第一个资源,并在同一时隙内稍后的一段时间内检测到第二个DCI格式1_0或DCI格式1_1指示了携带相应HARQ反馈信息的PUCCH发送的第二个资源,如果包含第二个DCI格式的PDCCH接收不早于PUCCH发送的第一个资源的起始符号N
3个符号,则UE不期望在上述时隙内的PUCCH资源上复用与第二个DCI格式相应的HARQ反馈信息。
再例如,当为高优先级业务(例如URLLC)生成独立的HARQ-ACK码书时,为了满足URLLC的时延要求,需要进一步增强UE的处理能力,例如对于UE处理能力N
3,针对不同子载波的N
3取值例如如下:
例如,当μ=0,N
3=1;当μ=1,N
3=2;当μ=2,N
3=4;当μ=3,N
3=5。或者,例如,当μ=0,N
3=1.5;当μ=1,N
3=2;当μ=2,N
3=4.5;当μ=3,N
3=5。
值得注意的是,以上仅示例性对UE处理能力参数N
3进行了说明,但本发明不限于此。另外,关于以上μ和N
3的具体内容或定义,可以参考相关技术。
如图5所示,该方法还可以包括:
步骤503,终端设备接收网络设备发送的包含计数下行分配指示(C-DAI,counter downlink assignment indicator)和合计下行分配指示(T-DAI,total downlink assignment indicator)的一个或多个DCI;
例如,终端设备可以在一个时隙中检测到一个或多个DCI。值得注意的是,步骤503并不一定在步骤502之后执行,也可以在步骤502或步骤501之前执行,或者与步骤502、501并行执行。
在本实施例中,网络设备计算所述C-DAI和所述T-DAI;此外,用于计算所述C-DAI和所述T-DAI的DCI指示在同一个时隙且同一PUCCH资源上发送HARQ反馈信息。
例如,C-DAI为截止到当前服务小区与当前PDCCH监测机会所累计的,与PDSCH接收或SPS PDSCH释放相关联的DCI格式1_0或DCI格式1_1出现的{服务 小区,PDCCH监测机会}对的数目;其中上述DCI不仅指示在同一个时隙(slot)上发送HARQ反馈信息,而且指示了在同一个PUCCH资源上发送HARQ反馈信息。
而T-DAI为截止到当前PDCCH监测机会,与PDSCH接收或SPS PDSCH释放相关联的DCI格式1_0或DCI格式1_1出现的{服务小区,PDCCH监测机会}对的总数,并随着PDCCH监测机会的更新而更新;其中上述DCI不仅指示在同一个时隙(slot)上发送HARQ反馈信息,而且指示了在同一个PUCCH资源上发送HARQ反馈信息。
如图5所示,该方法还可以包括:
步骤504,终端设备确定动态HARQ-ACK码书;
例如,终端设备可以执行3GPP TS 38.213中第9.1.2.1节的伪代码,来确定动态HARQ-ACK码书中的O
ACK个HARQ反馈信息比特。
步骤505,终端设备确定发送动态HARQ-ACK码书的PUCCH资源;
例如,终端设备可以基于在所有检测到的DCI格式1_0或DCI格式1_1中、域‘PDSCH-to-HARQ_feedback timing indicator’指向同一个时隙、且同一个PUCCH资源来发送携带HARQ反馈信息的PUCCH的一个DCI格式1_0或DCI格式1_1中的PUCCH资源指示域,确定发送HARQ-ACK码书的PUCCH资源。其中,检测到的多个DCI格式可以先对同一个PDCCH检测机会索引的不同服务小区索引进行升序排列,再对不同PDCCH监测机会索引进行升序排列。
例如,UE共检测到5个DCI,分别为DCI 1、DCI 2、DCI 3、DCI 4和DCI 5,其中DCI 1、DCI 3和DCI 4为DCI格式1_0,DCI 2、和DCI 5为DCI格式1_1,这5个DCI的‘PDSCH-to-HARQ_feedback timing indicator’域均指向同一时隙且同一PUCCH资源,则UE根据其中一个DCI(例如DCI 5)中的PUCCH资源指示域,确定发送HARQ-ACK码书的PUCCH资源。
如图5所示,该方法还可以包括:
步骤506,终端设备在上述确定的PUCCH资源上发送动态HARQ-ACK码书。
由此,在确定PUCCH资源时,通过指向同一个时隙且同一个PUCCH资源的DCI,PUCCH资源能够被相互独立地确定;此外,动态HARQ-ACK码书能够被相互独立地确定,能够满足某一些场景(例如URLLC)在进行HARQ反馈时高可靠低时延的要求。
值得注意的是,以上附图5仅对本发明实施例进行了示意性说明,但本发明不限于此。例如可以适当地调整各个步骤之间的执行顺序,此外还可以增加其他的一些步骤或者减少其中的某些步骤。本领域的技术人员可以根据上述内容进行适当地变型,而不仅限于上述附图5的记载。
值得注意的是,以上各个实施例仅对本发明实施例进行了示例性说明,但本发明不限于此,还可以在以上各个实施例的基础上进行适当的变型。例如,可以单独使用上述各个实施例,也可以将以上各个实施例中的一种或多种结合起来。
由上述实施例可知,终端设备根据接收到的指向同一时隙且同一PUCCH资源的多个DCI中的一个DCI,确定发送HARQ反馈信息的PUCCH资源。由此,不同业务(例如URLLC与eMBB)的PUCCH资源能够被相互独立地确定,能够满足某一些场景(例如URLLC)在进行HARQ反馈时高可靠低时延的要求。
实施例2
本发明实施例提供一种反馈信息的接收方法,从网络设备侧(即反馈信息的接收侧)进行说明,与实施例1相同的内容不再赘述。
图6是本发明实施例的反馈信息的接收方法的一示意图,如图6所示,该方法包括:

PRI,使得所述PDSCH接收或所述SPS PDSCH释放的HARQ反馈信息在同一时隙且同一PUCCH资源上被发送。
在一个实施例中,所述终端设备还根据处理能力参数N
3调整所述PDCCH检测机会。
在一个实施例中,在所述终端设备在一个时隙内检测到第一DCI指示了携带相应反馈信息的PUCCH发送的第一个资源,并且在同一时隙内再检测到第二DCI指示了携带相应反馈信息的PUCCH发送的第二个资源的情况下,
如果包含所述第二DCI的PDCCH接收时间不早于所述PUCCH发送的第一个资源的起始符号N
3个符号,则所述终端设备确定在所述时隙内的PUCCH资源上不复用与所述第二DCI相应的反馈信息,或者所述终端设备不期望在所述时隙内的PUCCH资源上复用与所述第二DCI相应的反馈信息。
在一个实施例中,网络设备还可以计算计数下行分配指示(C-DAI)和合计下行分配指示(T-DAI);其中,用于计算所述C-DAI和所述T-DAI的DCI指示在同一个时隙且同一PUCCH资源上发送HARQ反馈信息;以及所述网络设备向所述终端设备 发送所述计数下行分配指示(C-DAI)和合计下行分配指示(T-DAI)。
值得注意的是,以上各个实施例仅对本发明实施例进行了示例性说明,但本发明不限于此,还可以在以上各个实施例的基础上进行适当的变型。例如,可以单独使用上述各个实施例,也可以将以上各个实施例中的一种或多种结合起来。
由上述实施例可知,终端设备根据接收到的指向同一时隙且同一PUCCH资源的多个DCI中的一个DCI,确定发送HARQ反馈信息的PUCCH资源。由此,不同业务(例如URLLC与eMBB)的PUCCH资源能够被相互独立地确定,能够满足某一些场景(例如URLLC)在进行HARQ反馈时高可靠低时延的要求。
