NR Rel-15系统中支持两种HARQ-ACK码本:Type-1 HARQ-ACK码本和Type-2 HARQ-ACK码本。
为便于理解本申请,下面对Type-2 HARQ-ACK码本进行说明。
Type-2 HARQ-ACK码本采用动态的方式确定HARQ-ACK码本的比特数,即终端根据接收到的DCI,确定实际调度的PDSCH、SPS PDSCH释放(release)指示、SCell休眠指示(SCell dormancy)所需要的HARQ-ACK反馈比特数。特别地,为了应对除最后一个PDCCH之外的其余PDCCH漏检的问题,引入了下行分配索引(Downlink assignment index,DAI)指示。图2是本申请实施例提供的通过累计PDSCH接收数目方式确定DAI的示例。假设基站在单载波上发送基于TB传输的PDSCH,且每一个DCI只能调度1个码字(code word),如图2所示,基站在载波1上发送PDSCH 1~PDSCH 4,分别对应DAI=1~4,终端由于漏检调度PDSCH 3的PDCCH,导致PDSCH 3并未接收,但是终端收到PDSCH 4,且对应的DAI=4,则终端可以判断出漏检PDSCH 3,则将反馈4比特HARQ-ACK给基站。
在多载波场景下,DAI又分为下行分配指示计数(counter-DAI,C-DAI)和下行分配指示总数(total DAI,T-DAI)。
其中,C-DAI表示到当前服务小区和当前PDCCH监听时机,与DCI格式关联的PDSCH接收、SPS PDSCH释放或者指示的SCell休眠的累计数目(A value of the counter downlink assignment indicator(DAI)field in DCI formats denotes the accumulative number of{serving cell,PDCCH monitoring occasion}-pair(s)in which PDSCH reception(s),SPS PDSCH release or SCell dormancy indication associated with the DCI formats is present up to the current serving cell and current PDCCH monitoring occasion)。
T-DAI表示到当前PDCCH监听时机,所有服务小区上的,与DCI格式关联的PDSCH接收、SPS PDSCH释放或者指示的SCell休眠的累计数目(The value of the total DAI,when present[5,TS 38.212],in a DCI format denotes the total number of{serving cell,PDCCH monitoring occasion}-pair(s)in which PDSCH reception(s),SPS PDSCH release or SCell dormancy indication associated with DCI formats is present,up to the current PDCCH monitoring occasion m and is updated from PDCCH monitoring occasion to PDCCH monitoring occasion)。
以DCI中包含2比特C-DAI和2比特T-DAI为例,type-2 HARQ-ACK码本的构建过程如下:
从小到大遍历所有PDCCH监听时机,从小到大遍历所有的服务小区索引;初始化第一临时值为0;初始化j=0,其中j表示C-DAI达到最大值的次数(counter DAI为循环计数,即1,2,3,4,1,2,3,4,1,2,…,其中第一个1表示1,第二个1实际表示5。如果在PDCCH监听时机m,服务小区c上有PDSCH或者有一个指示SPS PDSCH释放或者SCell休眠的PDCCH,判断C-DAI的值和第一临时值的大小关系;如果C-DAI小于等于第一临时值,则将j+1;否则,更新第一临时值为C-DAI的取值。如果终端在所有载波上均只配置接收一个TB,则在第4*j+C-DAI-1的比特位上填充此小区的HARQ-ACK比特; 如果终端在至少一个载波上配置接收2个TB,且配置了harq-ACK-SpatialBundlingPUCCH,则在第4*j+C-DAI-1的比特位上填充此小区两个TB的HARQ-ACK逻辑与后的取值;如果终端在至少一个载波上配置接收2个TB,且没有配置harq-ACK-SpatialBundlingPUCCH,则在第4*j+2*(C-DAI-1)的比特位上填充此小区第一个TB的HARQ-ACK比特信息,在第4*j+2*(C-DAI-1)+1的比特位上填充此小区第二个TB的HARQ-ACK信息。确定总的HARQ-ACK比特数,记为O ack,若在上述执行过程中,在某些比特位置上未填充相应的HARQ-ACK信息,则在这些比特位置上填充NACK。
此外,NR还支持基于码块组(Code Block Group,CBG)的传输,对于基于CBG的下行接收,终端将一个传输块(TB)内包含的所有编码块(CB),以尽量平均的原则,分配给S个CBG,其中S表示每个TB包括的CBG的数量,S的确定方式为S=min(K,C),其中K为基站配置的每个TB的最大CBG的数量,C为TB所包含的CB的数量。
如果终端在一个下行小区集合

上配置了基于CBG的传输,在另一个下行小区集合
Figure PCTCN2021092844-appb-000002
上没有配置基于CBG的传输,则终端可按照如下规则或方式确定HARQ-ACK码本:
终端生成两个HARQ-ACK子码本,其中一个HARQ-ACK子码本包括SPS PDSCH释放、SPS PDSCH接收、Scell休眠指示、在

Figure PCTCN2021092844-appb-000004
小区上基于TB的PDSCH传输,对应的HARQ-ACK比特;另一个HARQ-ACK子码本包括
Figure PCTCN2021092844-appb-000005
小区上基于CBG的传输对应的HARQ-ACK比特;接着,终端将这两个HARQ-ACK子码本附加在一起,例如将所述一个HARQ-ACK子码本附加在所述另一个HARQ-ACK子码本后面,形成最终的HARQ-ACK码本。
第17版本(Rel-17)中,为更好地支持长期演进(Long Term Evolution,LTE)系统和新空口(New Radio,NR)系统动态频谱共享(Dynamic Spectrum Sharing,DSS)。对于LTE和NR共存的载波,为了避免对LTE系统产生干扰,NR系统传输无法使用LTE系统控制资源集(Control Resource Set,CORESET)和LTE系统物理下行控制信道(Physical Downlink Control Channel,PDCCH)的资源,因此,在共存的载波上,NR PDCCH的容量将会受到影响。
针对上述问题,本申请提出了一种技术方案,通过将一个DCI涉及为可用于调度至少两个不同载波的PDSCH,例如在PCell或SCell上的一个DCI可以调度PCell和SCell上的PDSCH。基于此,至少两个载波上的PDSCH对应的HARQ-ACK是否在相同的PUCCH资源传输,以及如何传输是进一步需要完善的问题。为便于描述本申请的方案,本申请将用于调度一个载波的PDSCH的DCI记为第一DCI格式(DCI format),将用于调度至少两个个载波的PDSCH的DCI记为第二DCI格式。
如果不考虑一个DCI调度两个载波的PDSCH的场景,以2比特C-DAI为例,按照DAI循环计数和type-2 HARQ-ACK码本生成的机制,终端能实现最多应对连续3个DCI漏检的性能。图3是本申请实施例提供的单载波下终端对抗DCI漏检的能力的示例。如图3所示,以基于TB的传输为例,按照type-2码本生成的机制,若终端先收到一个DCI调度PDSCH 1,其包含的DAI=1,再收到一个DCI调度PDSCH 5,其包含的DAI=1,终端即可以知道DAI已经循环计数到最大值又重新计数到了1,漏检了包含DAI=2/3/4的DCI。
然而,如果考虑一个DCI调度两个载波的PDSCH的场景,若DAI(例如C-DAI和/或T-DAI)按照上述设计与计数原则,则会降低DCI漏检性能。图4是本申请实施例提供的多载波下终端对抗DCI漏检的能力的示例。如图4所示,以基于TB的传输为例,基站在PDCCH监听时机(monitoring occasion)1发送第一个DCI,调度载波1的PDSCH 1和载波2的PDSCH 2,在PDCCH监听时机2发送第二个DCI,调度载波1的PDSCH 3和载波2的PDSCH 4,在PDCCH监听时机3发送第三个DCI,调度载波1的PDSCH 5,若终端只漏检第一个DCI,可以通过第二个DCI包含的DAI为3,知道漏检了包含DAI=1和DAI=2的DCI,但是如果终端漏检了前两个DCI,那么终端将认为第三个DCI是第一个DCI,无从得知漏检了包含DAI=1/2/3/4的两个DCI。
由此可见,在不改变DAI设计的前提下,一个DCI调度两个载波的PDSCH的场景,终端只能实现应对连续1个DCI漏检的性能。
本申请将所述第二DCI格式调度的至少两个PDSCH对应至少一个PDSCH组,有利于针对不同PDSCH组构建子码本,进而,针对所述第二DCI格式,有利于提升对抗DCI漏检的能力。具体而言,在一个DCI调度两个不同载波上的PDSCH传输场景下,不同载波的PDSCH的HARQ-ACK在相同的PUCCH资源上反馈,通过将对应不同载波的PDSCH,或者对应不同DCI格式的HARQ-ACK信息进行分组,来构建Type-2 HARQ-ACK码本的机制,在不增加DAI比特数的前提下,能够实现和R15/R16相同的对抗DCI漏检的能力。
图5是根据本申请实施例提供的无线通信方法200的示意性流程图,所述方法200可以由终端设备和网络设备交互执行。图5中所示的终端设备可以是如图1所示的终端设备,图5中所示的网络设 备可以是如图1所示的接入网设备。

其中,所述至少一个DCI包括第一DCI格式和/或第二DCI格式,所述第一DCI格式用于调度一个物理下行共享信道PDSCH,所述第二DCI格式用于调度至少两个PDSCH,所述至少两个PDSCH对应至少一个PDSCH组。
作为示例,针对所述至少一个DCI中的每一个DCI调度的PDSCH接收、SPS PDSCH释放指示或者辅小区SCell休眠指示进行分组后,确定或者生成相应的HARQ-ACK比特,这些HARQ-ACK比特可用于组成所述目标HARQ-ACK码本。可选的,所述至少一个PDSCH分别对应至少一个HARQ-ACK子码本,所述至少一个HARQ-ACK子码本用于构成所述目标HARQ-ACK码本。
基于以上技术方案,将所述第二DCI格式设计为用于调度至少两个PDSCH,完善了调度PDSCH的方式,能够提升系统性能。特别是,对于LTE和NR共存的载波,通过所述第二DCI格式调度至少两个PDSCH,能够避免NR对LTE系统产生干扰,即使NR传输无法使用LTE的CORESET和LTE的PDCCH资源,也能够确保终端设备对PDSCH进行HARQ-ACK反馈,保证了通信质量。此外,将所述至少两个PDSCH对应至少一个PDSCH组,有利于针对不同PDSCH组构建子码本,进而,针对所述第二DCI格式,有利于提升对抗DCI漏检的能力。
需要说明的是,本申请实施例对所述第一DCI格式的具体类型不作限定。例如所述第一DCI格式包括但不限于:DCI格式1_0/1_1/1_2。

下面结合实施例对本申请的方案进行说明。
实施例1:
本实施例中,假设终端被配置了三个载波集合,即第一载波集合至第三载波集合。
其中,针对第一载波集合,终端只配置了第一DCI格式;针对第二载波集合,终端只配置了第二DCI格式;针对第三载波集合,终端配置了第一DCI格式和第二DCI格式。针对所述第一载波集合至所述第三载波集合均没有被配置第一参数和第二参数,所述第一参数用于使能HARQ-ACK空间捆绑,所述第二参数用于指示一个DCI可以调度的最大的码字数。
基于此,终端针对第一载波集合和第三载波集合中的第一DCI格式调度的PDSCH,SPS PDSCH释放、SPS PDSCH接收、指示的SCell休眠、所述第二DCI格式调度的第一PDSCH,生成第一HARQ-ACK子码本;在第一HARQ-ACK子码本中,对每个DAI(例如C-DAI和/或T-DAI),终端生成1比特HARQ-ACK信息。终端针对第二载波集合和第三载波集合中的第二DCI格式调度的第二PDSCH,生成第二HARQ-ACK子码本;在第二HARQ-ACK子码本中,对每个DAI(例如C-DAI和/或T-DAI),终端生成1比特HARQ-ACK信息。
图8是本申请实施例提供的终端均未被配置第一参数和第二参数的情况下目标HARQ-ACK码本的示例。
如图8所示,基站在PDCCH监听时机1的载波1收到第二DCI格式,调度在载波1和载波2上传输的PDSCH 1和PDSCH 2;基站在PDCCH监听时机2的载波1收到第二DCI格式,调度在载波1和载波2上传输的PDSCH 3和PDSCH 4;基站在PDCCH监听时机3的载波3上收到第一DCI格式,调度载波3上传输的PDSCH 5;基站在PDCCH监听时机4的载波1上收到第一DCI格式,调度载波1上传输的PDSCH 6,在PDCCH监听时机4的载波2上收到第一DCI格式,调度载波2上传输的PDSCH 7,在PDCCH监听时机4的载波3上收到第一DCI格式,调度载波3上传输的PDSCH 8。
基于本申请的方案,第一DCI格式调度的PDSCH以及第二DCI格式调度的低载波索引的PDSCH都属于第一PDSCH组,第二DCI格式调度的高载波索引的PDSCH属于第二PDSCH组,针对所述第一PDSCH组和所述第二PDSCH组分别计数DAI(即C-DAI和T-DAI)。则终端确定对应第一PDSCH组的第一HARQ-ACK信息包括6比特{b 1,b 2,b 3,b 4,b 5,b 6},分别对应于PDSCH 1,PDSCH 3,PDSCH 5~8。终端确定对应于第二PDSCH组的第二HARQ-ACK信息包括2比特{b 1,b 2},分别对应于PDSCH 2和PDSCH 4;终端将第二HARQ-ACK信息附加在第一HARQ-ACK信息后面,共得到8比特HARQ-ACK信息。
实施例2:
本实施例中,假设终端被配置了三个载波集合,即第一载波集合至第三载波集合。
针对第一载波集合,终端只配置了第一DCI格式;针对第二载波集合,终端只配置了第二DCI格式;针对第三载波集合,终端配置了第一DCI格式和第二DCI格式。针对所述第一载波集合至所述第三载波集合均没有被配置第一参数和第二参数,针对第一载波集合和第二载波集合被配置基于CBG传输(例如最大CBG的数目为4)。
基于此,终端针对第一载波集合和第三载波集合中的所述第一PDSCH组中的基于TB的PDSCH接收,生成第三HARQ-ACK子码本;在第三HARQ-ACK子码本中,对每个DAI(例如C-DAI和/或T-DAI),终端生成1比特HARQ-ACK信息。终端针对第一载波集合和第三载波集合中的所述第一PDSCH组中的基于CBG的PDSCH接收,生成第四HARQ-ACK子码本;在第四HARQ-ACK子码本中,对每个DAI(例如C-DAI和/或T-DAI),终端生成4比特HARQ-ACK信息。终端针对第二载波集合和第三载波集合中的第二PDSCH组中的基于TB的PDSCH接收,生成第五HARQ-ACK子码本;在第五HARQ-ACK子码本中,对每个DAI(例如C-DAI和/或T-DAI),终端生成1比特HARQ-ACK信息。终端针对第二载波集合和第三载波集合中的第二PDSCH组中的基于CBG的PDSCH接收,生成第六HARQ-ACK子码本;在第六HARQ-ACK子码本中,对每个DAI(例如C-DAI和/或T-DAI),终端生成4比特HARQ-ACK信息。
图9是本申请实施例提供的终端没有被配置的第一参数和第二参数的情况下基于CBG传输的目标HARQ-ACK码本的示例。
如图9所示,基站在PDCCH监听时机1的载波1收到第二DCI格式,调度在载波1和载波2上传输的PDSCH 1和PDSCH 2;基站在PDCCH监听时机2的载波1收到第二DCI格式,调度在载波1和载波2上传输的PDSCH 3和PDSCH 4;基站在PDCCH监听时机3的载波3上收到第一DCI格式,调度载波3上传输的PDSCH 5;基站在PDCCH监听时机4的载波1上收到第一DCI格式,调度载波1上传输的PDSCH 6,在PDCCH监听时机4的载波2上收到第一DCI格式,调度载波2上传输的PDSCH 7,在PDCCH监听时机4的载波3上收到第一DCI格式,调度载波3上传输的PDSCH 8。
基于本申请的方案,终端针对所述第一PDSCH组中基于TB传输的PDSCH 5、PDSCH 7、PDSCH 8,生成3*1=3比特HARQ-ACK;终端针对所述第一PDSCH组中基于CBG传输的PDSCH 1、PDSCH 3、PDSCH 6,生成3*4=12比特HARQ-ACK;终端针对所述第二PDSCH组中基于TB传输的PDSCH 2、PDSCH 4,生成2*1=2比特HARQ-ACK;所述第二PDSCH组中没有基于CBG传输的PDSCH;因此,终端共生成3+12+2=17比特HARQ-ACK。本申请对HARQ-ACK的顺序不作具体限定。例如,可以为如下两种方式:
方式一:
所述第一PDSCH组中基于TB的HARQ-ACK(3比特)、所述第一PDSCH组中基于CBG的HARQ-ACK(12比特)、所述第二PDSCH组中基于TB的HARQ-ACK(2比特)、所述第二PDSCH组中基于CBG的HARQ-ACK(为0比特)。
方式二:
所述第一PDSCH组中基于TB的HARQ-ACK(3比特)、所述第二PDSCH组中基于TB的HARQ-ACK(2比特)、所述第一PDSCH组中基于CBG的HARQ-ACK(12比特)、所述第二PDSCH组中基于CBG的HARQ-ACK(为0比特)。
本实施例中,所述第二DCI格式中包括两个T-DAI指示域,所述两个T-DAI分别对应于所述第一PDSCH组和所述第二PDSCH组,或者对应于上文所述的第一HARQ-ACK信息和第二HARQ-ACK信息,或者对应于上文所述的第一HARQ-ACK子码本和第二HARQ-ACK子码本。包含两个T-DAI的好处在于:若两组PDSCH共享一个T-DAI指示域,当终端收到所述第一PDSCH组C-DAI=3,所述第一PDSCH组C-DAI=2,T-DAI=7时,终端知道漏检了两个DCI,但是终端无法得知漏检的DCI调度的PDSCH为第一PDSCH组的PDSCH还是第二PDSCH组的PDSCH,因此无法得知对应的2比特NACK的填充位置,即包含两个T-DAI的好处在于,使得终端和基站对HARQ-ACK码本的比特顺序的理解保持一致。
实施例3:
本实施例中,所述第二DCI格式中包括一个T-DAI指示域。
图10是本申请实施例提供的共享T-DAI指示域的第一PDSCH组和所述第二PDSCH组的示例。
如图10所示,基站在PDCCH监听时机1的载波1收到第二DCI格式,调度在载波1和载波2上传输的PDSCH 1和PDSCH 2;基站在PDCCH监听时机2的载波1收到第二DCI格式,调度在载波1和载波2上传输的PDSCH 3和PDSCH 4;基站在PDCCH监听时机3的载波3上收到第一DCI格式,调度载波3上传输的PDSCH 5;基站在PDCCH监听时机4的载波1上收到第一DCI格式,调度载波1上传输的PDSCH 6,在PDCCH监听时机4的载波2上收到第一DCI格式,调度载波2上传输的PDSCH 7,在PDCCH监听时机4的载波3上收到第一DCI格式,调度载波3上传输的PDSCH 8。
基于本申请的方案,若所述第一PDSCH组和所述第二PDSCH组,共享T-DAI指示域,即T-DAI一起计数两个组的PDSCH(如图10中的T-DAI的计数规则),则当终端漏检了PDCCH监听时机4的载波2和载波3上的两个DCI时,终端只能知道对于第一PDSCH组,共有4比特有效HARQ-ACK信息,对于第二PDSCH组,只有2比特HARQ-ACK有效信息,但是根据在PDCCH监听时机4中收到的T-DAI=4,可以知道终端共需要生成8比特HARQ-ACK信息,那么对于剩余8-(4+2)=2比特NACK,是应该填充在第一PDSCH组的HARQ-ACK后面,还是应该填充在第二PDSCH组的HARQ-ACK后面,终端是不清楚的,有可能造成终端填充NACK比特位置错误,导致基站和终端对8比特HARQ-ACK位置的理解不一致。
