本申请实施例中术语“和/或”,描述关联对象的关联关系,表示可以存在三种关系,例如,A和/或B,可以表示:单独存在A,同时存在A和B,单独存在B这三种情况。字符“/”一般表示前后关联对象是一种“或”的关系。
本申请实施例中术语“多个”是指两个或两个以上,其它量词与之类似。
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清楚、完整地描述,显然,所描述的实施例仅仅是本申请一部分实施例,并不是全部的实施例。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。
本申请实施例提供了一种混合自动重传反馈方法及装置。其中,方法和装置是基于同一申请构思的,由于方法和装置解决问题的原理相似,因此装置和方法的实施可以相互参见,重复之处不再赘述。
如图1所示,本申请实施例提供的一种混合自动重传反馈方法,包括:
步骤101,接收下行控制信息DCI,所述DCI调度多个小区的物理下行共享信道PDSCH,所述DCI指示在调度的各小区的PDSCH中最晚被调度PDSCH与物理上行控制信道(Physical Uplink Control Channel,PUCCH)之间的时隙数。
这里,终端接收到调度多个小区的PDSCH的DCI。应该知道的是,DCI调度的该多个小区可以称为被调度小区。
步骤102,确定第一集合;其中,所述第一集合中包含第一间隔,所述第一间隔用于表示PDSCH与PUCCH之间的时隙数。
这里,第一集合即第一间隔K1的集合,DCI指示的在调度的各小区的PDSCH中最晚被调度PDSCH与PUCCH之间的时隙数是属于该第一集合的,即DCI指示终端使用的K1。该第一集合可以是网络设备(如基站)通过高层信令(如无线资源控制(Radio Resource Control,RRC)信令)配置给终端的,则终端确定第一集合,可以是通过接收高层信令中的配置信息确定第一集合,或者是接收高层信令中的第一集合。
步骤103,根据第二间隔对所述第一集合进行处理,得到第二集合;其 中,所述第二间隔用于表示DCI与PDSCH之间的时隙数。
这里,终端针对步骤101接收到的DCI是调度多个小区PDSCH的DCI的情况,会根据第二间隔K0和步骤102确定的第一集合来得到扩展的第一间隔的集合,即第二集合。
步骤104,根据所述第二集合,确定所述DCI调度的各小区的静态混合自动重传请求(Hybrid Automatic Repeat Request,HARQ)码本对应的PDSCH接收时机。
本步骤中,终端根据步骤103得到第二集合来确定DCI调度的各小区的静态HARQ码本对应的PDSCH接收时机。
如此,通过上述步骤101-104,终端在接收DCI并确定第一集合之后,能够针对该DCI调度多个小区的PDSCH的情况,利用第二间隔对第一集合扩展得到第二集合,然后使用该第二集合确定DCI调度的各小区的静态HARQ码本对应的PDSCH接收时机,从而实现一个DCI调度多个小区上的PDSCH情况下的混合自动重传反馈。
需要说明的是,本申请实施例的方法适用于多小区PDSCH调度时域资源分配(Time Domain Resource Allocation,TDRA)表中,每个小区对应相同行索引的K0不同的情况。例如,如下表1所示的多小区调度TDRA表:
表1
其中,NULL表示对应(起止和长度指示符(Start and Length Indicator Value,SLIV)无效。如对于表1,当行索引是2时,小区-3没有被调度,即可以理解为小区-3只配置了一个2行的TDRA表。应该知道的是,TDRA表可以是基站通过RRC信令配置或者在协议中指定的默认TDRA表。
当然,DCI调度多个小区的PDSCH时,该多个小区可以是TDRA表中的部分小区或全部小区。该DCI可以指示该多个小区的每个小区的TDRA行 索引。
可选地,该实施例中,对于该多个小区,第一集合可以相同也可以不同。
还需要说明的是,该实施例中,由于DCI是用来调度多个小区的PDSCH的,故,步骤102确定的第二集合可以包括多个第二集合,如第二集合与该多个小区一一对应。
本申请实施例还提供的一种混合自动重传反馈方法,包括:
接收下行控制信息DCI,所述DCI调度多个小区的物理下行共享信道PDSCH,所述DCI指示在被调度的各小区的PDSCH中最晚PDSCH与物理上行控制信道PUCCH之间的时隙数;
根据第二集合,确定所述DCI调度的各小区的静态混合自动重传请求HARQ码本对应的PDSCH接收时机;
其中,所述第二集合根据第一集合以及第二间隔得到,所述第一集合中包含第一间隔,所述第一间隔用于表示PDSCH与PUCCH之间的时隙数,所述第二间隔用于表示DCI与PDSCH之间的时隙数。
可选地,所述第二集合根据第一集合以及第二间隔得到(或步骤103),包括:
获取时域资源分配TDRA表中所述各小区对应的第二间隔;
针对所述多个小区的每个第一小区,分别执行:
根据获取的第二间隔,确定所述第一小区在TDRA表中各行索引对应的调整参数;
基于所述第一小区在TDRA表中不同行的行索引,分别执行间隔处理操作:
根据第i+1个行索引的调整参数,确定所述第i+1个行索引对应的调整后的第一集合,i为大于或等于1的整数,i为大于或等于1的整数;
根据所述调整后的第一集合和确定的第i个行索引的第i个间隔处理结果,确定所述第i+1个行索引的第i+1个间隔处理结果,之后跳转执行第i+2个行索引对应的间隔处理操作;
在得到所述第一小区在TDRA表中最后一个行索引对应的间隔处理结果后,将得到的所述最后一个行索引对应的间隔处理结果确定为所述第一小区 的第二集合。
其中,获取时域资源分配TDRA表中所述各小区对应的第二间隔。
即,终端会基于TDRA表,分别获取多个被调度小区对应的K0。这里,每个小区对应的K0可以是一个或多个。例如,如表1所示,获取小区-3对应的K0包括:K0=4和K0=0;获取小区-4对应的K0包括:K0=6,K0=2和K0=5。在某个行索引出现无效SLIV时,不计算K0。
之后,终端针对被调度的多个小区来确定每个小区的第二集合。这里,该多个小区中的各小区均可称为第一小区。第二集合中的第一间隔可以记为k1。
而对于每个第一小区,终端针对所述第一小区在TDRA表中第i+1个行索引,执行间隔处理操作,在得到所述第一小区在TDRA表中最后一个行索引对应的间隔处理结果后,将得到的所述最后一个行索引对应的间隔处理结果确定为所述第一小区的第二集合。
其中,如表1所示,TDRA表中行索引往往是从0开始,故,对于行索引r,r=i-1,也就是说,第1个行索引对应行索引r=0。
故,上述步骤针对第一小区,是从第2个行索引,也就是r=1开始执行间隔处理操作,直至遍历到该第一小区对应的最大r值。
以表1为例,假设该多个小区包括小区-1,小区-2,小区-3和小区-4(DCI调度多个小区的PDSCH,该多个小区是TDRA表中的全部小区)。按照上述步骤,终端会分别获取小区-1,小区-2,小区-3和小区-4对应的K0,此时,小区-1对应的K0可记为(2,1,1),小区-2对应的K0可记为(3,6,3),小区-3对应的K0可记为(4,0)和小区-4对应的K0可记为(6,2,5)。在确定第一小区(如小区-3)的第二集合时,终端会针对小区-3在表1中第2个行索引(行索引1)开始,根据小区-3对应行索引1的调整参数(如调整参数2),确定小区-3对应行索引1的调整后的第一集合(如集合2),之后根据集合2和小区-3对应行索引0的第1个间隔处理结果,得到小区-3对应行索引1的第2个间隔处理结果。由于小区-3对应的最大r值为1,则所确定的小区-3对应行索引1的第2个间隔处理结果即小区-3的第二集合。
当然,若小区-3对应的最大r值为2,则还需要根据小区-3对应行索引2 的调整参数,确定小区-3对应行索引2的调整后的第一集合(如集合3),之后根据集合3和小区-3对应行索引1的第2个间隔处理结果,得到小区-3对应行索引2的第3个间隔处理结果。此时,小区-3对应行索引2的第3个间隔处理结果即小区-3的第二集合。
可选地,通过以下方式确定第i个行索引的第i个间隔处理结果,包括:
当i=1时,根据所述第一小区对应的第1个行索引的调整参数,确定所述第1个行索引对应的调整后的第一集合;
根据所述第1个行索引的调整后的第一集合,得到所述第1个行索引的第1个间隔处理结果;或者,根据所述第一集合和所述第1个行索引对应的调整后的第一集合,得到所述第1个行索引的第1个间隔处理结果。
也就是说,对于第一小区对应第1个行索引(行索引0)的第1个间隔处理结果(简称第一小区的第1个间隔处理结果),可以是该第一小区对应第1个行索引的调整后的第一集合,也可以是第一集合和该第一小区对应第1个行索引的调整后的第一集合的并集。
可选地,该实施例中,所述根据获取的第二间隔,确定所述第一小区在TDRA表中各行索引对应的调整参数,包括:
针对所述第一小区在TDRA表中的其中一个行索引,基于所述第一小区中该行索引对应的第二间隔以及所述多个小区中该行索引对应的最大第二间隔,确定所述第一小区中该行索引的调整参数。
也就是说,确定第一集合在一个行索引下的调整参数时,会使用该行索引对应的第一小区的K0和该行索引对应的多个小区中的最大K0。例如,上述示例中,小区-3对应行索引0的调整参数1,是基于行索引0对应的小区-3的K0(K0=4)和行索引0对应的小区-1,小区-2,小区-3和小区-4的最大K0(即max(2,3,4,6)=6)确定的。
可选地,所述基于所述第一小区中该行索引对应的第二间隔以及所述多个小区中该行索引对应的最大第二间隔,确定所述第一小区中该行索引的调整参数,包括:
通过公式ΔK0,r,c=max(K0,r,1,…,K0,r,n,…,K0,r,N)-K0,r,c,计算行索引r对应的所述第一小区的调整参数ΔK0,r,c
其中,K0,r,n表示所述多个小区中小区n的行索引r对应的第二间隔,N表示所述多个小区的小区数量,K0,r,c表示所述第一小区c中行索引r对应的第二间隔。
如此,在上述示例中,小区-3对应行索引0的调整参数(即ΔK0,0,3)的计算为:ΔK0,0,3=max(K0,0,1,…,K0,0,4)-K0,0,3=max(2,3,4,6)-4=6-4=2。当然,也可以得到小区-3对应行索引1的调整参数(即ΔK0,1,3),ΔK0,1,3=6。
可选地,该实施例中,所述根据第i+1个行索引的调整参数,确定所述第i+1个行索引对应的调整后的第一集合,i为大于或等于1的整数包括:
针对所述第一集合中的各个元素,分别与所述第i+1个行索引的调整参数相加,得到所述第i+1个行索引的调整后的第一集合。
即,终端要得到第一小区在第一行索引对应的调整后的第一集合,是将第一集合中各个K1加上该第一小区在该第一行索引下的调整参数后得到K1’的集合。具体的,第一小区(如小区c)对应行索引r的调整后的第一集合可记为K1’r,c集合。这里,K1’r,c集合中的第一间隔=K1集合的第一间隔+ΔK0,r,c
延续上例,小区-3对应行索引0的调整参数1等于2,小区-3对应行索引1的调整参数2等于6,若假设第一集合为{2,4,6},则小区-3对应行索引0的调整后的第一集合为{2+2,4+2,6+2}={4,6,8};而小区-3对应行索引1的调整后的第一集合为{2+6,4+6,6+6}={8,10,12}。
可选地,所述根据所述调整后的第一集合和所述第一小区对应第i个行索引的第i个间隔处理结果,确定所述第一小区对应所述第i+1个行索引的第i+1个间隔处理结果包括:
将所述调整后的第一集合和所述第一小区对应第i个行索引的第i个间隔处理结果求并集,将得到的并集结果作为所述第一小区对应所述第i+1个行索引的第i+1个间隔处理结果。
也就是说,终端是将该第一小区对应第i+1个行索引的调整后的第一集合和该第一小区对应第i个行索引的的第i个间隔处理结果的并集作为第一小区对应对应第i+1个行索引的的第i+1个间隔处理结果。
还需要说明的是,该实施例中,对于第一小区,若其还支持单小区调度,则对应行索引0,是将行索引0的调整后的第一集合和第一集合的并集,作 为该第一小区对应第1个行索引的第1个间隔处理结果;若其不支持单小区调度,则对应行索引0,是将行索引0的调整后的第一集合作为该第一小区对应第1个行索引的第1个间隔处理结果。
延续上例,小区-3对应的行索引0的调整后的第一集合为{4,6,8},小区-3对应的行索引1的调整后的第一集合为{8,10,12},若小区-3支持单小区调度,则小区-3对应的行索引0的第1个间隔处理结果为{2,4,6}∪{4,6,8}={2,4,6,8};而小区-3对应行索引1的第2个间隔处理结果为{8,10,12}∪{2,4,6,8}={2,4,6,8,10,12}。故,小区-3的第二集合为{2,4,6,8,10,12}。
该实施例中,第一小区对应第i个行索引的第i个间隔处理结果可以使用K1,T集合表示。
故,该实施例中,对于小区-3可得到下表2(由于表2是针对小区-3的,故省略c=3的标识):
表2
而若小区-3不支持单小区调度,则小区-3对应行索引0的第1个间隔处理结果为{空}∪{4,6,8}={4,6,8};而小区-3对应行索引1对应的第2个间隔处理结果为{8,10,12}∪{4,6,8}={4,6,8,10,12}。故,小区-3的第二集合为{4,6,8,10,12}。
故,该实施例中,对于小区-3可得到下表3(由于表3是针对小区-3的,故省略c=3的标识):
表3

这样,作为一个可选地示例1,终端接收到DCI,该DCI调度小区-1,小区-2,小区-3和小区-4的PDSCH,终端还接收到第一集合{2,4,6},则终端执行:
步骤1,接收基站通过RRC信令配置的TDRA表,如表1所示,在此不再赘述。
步骤2,根据基站配置的TDRA表和第一集合,确定该DCI调度对应的每个小区的第二集合。
情况1,对于支持单小区调度的小区(即支持多小区调度和支持单小区调度的小区),按照step 1a/2a执行:
Step 1a:设置该小区在r=0时,K1,T集合取第一集合和调整后的第一集合的并集。
Step 2a:遍历该小区在TDRA表的所有行,基于行索引对应的调整后的第一集合以及上一个行索引对应的K1,T集合,得到各个行索引对应的K1,T集合。遍历完成后,即该小区的最大行索引对应的K1,T集合即该小区的第二集合。假设小区-3支持单小区调度,对应的K1,T集合如上表2所示;假设小区-1支持单小区调度,对应的K1,T集合如下表4所示(由于表4是针对小区-1的,故省略c=1的标识):
表4
假设小区-2支持单小区调度,对应的K1,T集合如下表5(由于表5是针对小区-2的,故省略c=2的标识):
表5
情况2,对于不支持单小区调度的小区(即支持多小区调度但不支持单小区调度的小区),按照step 1b/2b执行:
Step 1b:设置该小区在r=0时,K1,T集合取空集和调整后的第一集合的并集。
Step 2b:遍历该小区在TDRA表的所有行,基于行索引对应的调整后的第一集合以及上一个行索引对应的K1,T集合,得到各个行索引对应的K1,T集合。遍历完成后,即该小区的最大行索引对应的K1,T集合即该小区的第二集合。
假设小区-3不支持单小区调度,对应的K1,T集合如上表3所示;假设小区-1不支持单小区调度,对应的K1,T集合如下表6所示(由于表6是针对小区-1的,故省略c=1的标识):
表6

假设小区-2不支持单小区调度,对应的K1,T集合如下表7(由于表7是针对小区-2的,故省略c=2的标识):
表7
此外,网络设备可以通过高层信令直接配置该第二集合,如网络设备发送RRC,配置DCI调度多个小区的PDSCH时该多个小区一一对应的第二集合。终端则可以直接使用配置的第二集合来确定PDSCH接收时机。
本申请实施例还提供一种混合自动重传反馈方法,由终端执行,所述方法包括:
接收下行控制信息DCI,所述DCI调度多个小区的物理下行共享信道PDSCH,所述DCI指示在被调度的各小区的PDSCH中最晚PDSCH与物理上行控制信道PUCCH之间的时隙数;
根据网络设备配置的第二集合,确定所述DCI调度的各小区的静态混合自动重传请求HARQ码本对应的PDSCH接收时机。
可选地,本申请实施例中记载的第二集合通过高层信令配置。
具体地,对于一个小区X,如果通过多小区调度信令,终端被配置调度该小区X的PDSCH。网络设备可以通过高层信令向该终端配置第二集合,第二集合可以通过以下至少一种方式得到:
方式一:若小区未配置单小区调度信令或者所述小区的激活部分带宽BWP处于休眠状态,则通过高层信令所配置的所述第二集合包含以下至少一 种方法:
方法1:通过高层信令配置的所述小区的第一K1数值集合,其中,所述K1表示PDSCH与PUCCH之间的时隙数;
方法2:通过高层信令配置的用于多小区调度的第一集合,其中,所述第一集合中包含第一间隔,所述第一间隔用于表示PDSCH与PUCCH之间的时隙数;
方法3:第二K1数值集合,其中,所述第二K1数值集合是根据用于承载HARQ-ACK信息的上行PUCCH信道的子载波间隔的数值确定的,所述子载波间隔的数值不同,所述第二K1数值集合中所包含的K1数值相同或者不同;
方法4:网络设备配置的DCI格式1-1对应的第一集合;
方法5:网络设备配置的DCI格式1-2对应的第一集合;或者,
方法6:网络设备配置的DCI格式1-1对应的第一集合与网络设备配置的DCI格式1-2对应的第一集合的并集,得到的并集集合。
需要说明的是,本申请实施例中记载的“小区未配置单小区调度信令”可以理解为:站在终端的角度,没有配置用于调度PDSCH的单小区调度信令,也就是终端没有接收在该小区进行单小区调度信令检测的配置信息或者说基站没有配置UE为该小区检测单小区调度调度信令,其中,单小区调度信令的格式包含DCI格式1-0、DCI格式1-1、DCI格式1-2或者其他一个DCI只多调度一个小区PDSCH数据的信令格式。
通过高层信令配置的用于多小区调度的第一集合,通常对于多小区调度,所述被调度小区对应的PDSCH为在被调度的各小区的PDSCH中最晚。其中,“所述被调度小区对应的PDSCH为在被调度的各小区的PDSCH中最晚”可以理解为:在多小区调度的场景下,多小区调度信令调度多个小区的PDSCH,这里被调度小区的PDSCH在多小区调度信令调度的多个小区对应的PDSCH中时隙最晚。
所述第二K1数值集合是根据用于承载HARQ-ACK信息的上行PUCCH信道的子载波间隔的数值确定的,具体包括:若对于用于承载HARQ-ACK信息的上行PUCCH信道的子载波间隔小于等于120KHz,第二K1数值集合 中K1={1,2,3,4,5,6,7,8};若子载波间隔等于480KHz,第二K1数值集合中K1={7,8,12,16,20,24,28,32};若子载波间隔等于960KHz,第二K1数值集合中K1={13,16,24,32,40,48,56,64}。
假设,网络设备配置的DCI格式1-1对应的第一集合,可以表示为dl-DataToUL-ACK;网络设备配置的DCI格式1-2对应的第一集合,可以表示为dl-DataToUL-ACK-1-2,那么网络设备配置的DCI格式1-1对应的第一集合与网络设备配置的DCI格式1-2对应的第一集合的并集,可以表示为dl-DataToUL-ACK和dl-DataToUL-ACK-1-2的并集。
方式二:若小区配置了单小区调度信令且所述单小区调度信令格式仅仅为回退格式,则通过高层信令所配置的所述第二集合包含以下至少一种方法:
方法1:通过高层信令配置的所述小区的第一K1数值集合,其中,所述K1表示PDSCH与PUCCH之间的时隙数;
方法2:第二K1数值集合,其中,所述第二K1数值集合是根据用于承载HARQ-ACK信息的上行PUCCH信道的子载波间隔的数值确定的,所述子载波间隔的数值不同,所述第二K1数值集合中所包含的K1数值相同或者不同;
或者,
方法3:所述第一K1数值集合与所述第二K1数值集合的并集得到的集合。
需要说明的是,回退格式为DCI格式1-0,且没有配置其他任何一个DCI只多调度一个小区PDSCH数据的信令格式,如没有配置DCI格式1-1,也没有配置DCI格式1-2。
所述第二K1数值集合是根据用于承载HARQ-ACK信息的上行PUCCH信道的子载波间隔的数值确定的,具体包括:若对于用于承载HARQ-ACK信息的上行PUCCH信道的子载波间隔小于等于120KHz,第二K1数值集合中K1={1,2,3,4,5,6,7,8};若子载波间隔等于480KHz,第二K1数值集合中K1={7,8,12,16,20,24,28,32};若子载波间隔等于960KHz,第二K1数值集合中K1={13,16,24,32,40,48,56,64}。
方式三:若小区配置了单小区调度信令、所述单小区调度信令的格式为 DCI格式1-1并且所述小区没有配置DCI格式1-2的调度信令,则通过高层信令所配置的所述第二集合包含以下至少一种方法:
方法1:通过高层信令配置的所述小区的第一K1数值集合,其中,所述K1表示PDSCH与PUCCH之间的时隙数;
方法2:网络设备配置的DCI格式1-1对应的第一集合;或者,
方法3:所述第一K1数值集合与所述网络设备配置的DCI格式1-1对应的第一集合的并集得到的集合。
方式四:若小区配置了单小区调度信令、所述单小区调度信令的格式为DCI格式1-2并且所述小区没有配置DCI格式1-1的调度信令,则通过高层信令所配置的所述第二集合包含以下至少一种方法:
方法1:通过高层信令配置的所述小区的第一K1数值集合,其中,所述K1表示PDSCH与PUCCH之间的时隙数;
方法2:网络设备配置的DCI格式1-2对应的第一集合;或者,
方法3:所述第一K1数值集合与所述网络设备配置的DCI格式1-2对应的第一集合的并集得到的集合。
方式五:若小区配置了单小区调度信令、所述单小区调度信令的格式为DCI格式1-2和DCI格式1-1,则通过高层信令所配置的所述第二集合包含以下至少一种方法:
方法1:网络设备配置的DCI格式1-1对应的第一集合与网络设备配置的DCI格式1-2对应的第一集合的并集,得到的并集集合;
方法2:通过高层信令配置的所述小区的第一K1数值集合,其中,所述K1表示PDSCH与PUCCH之间的时隙数;或者,
方法3:所述并集集合与所述第一K1数值集合的并集得到的集合。
需要说明的是,上述记载的五种方式有关第二集合的内容相关部分也适应于网络设备。
另外,该实施例中,考虑到多小区调度过程中,网络设备通过DCI中的PUCCH定时指示信息(k1-timing),表示PUCCH和调度PDSCH的时隙关系,这里PUCCH用于反馈混合自动重传请求应答(Hybrid automatic repeat request acknowledgement,HARQ-ACK)的信道;k1-timing指示范围基于第一集合; 在计算静态码本的PDSCH接收时机时,对于每个调度小区,根据新计算的第二集合即K1,T集合,循环所有的数值;由于第二集合的范围比第一集合的范围大,因此相对于调度小区的TDRA的所有SLIV行,存在一些冗余的SLIV信息,需要进行识别和剪除。
所以,可选地,所述方法(或步骤103之后)还包括:
根据TDRA表以及所述第一小区的第二集合,确定与所述第二集合中各个第一间隔对应的有效起止和长度指示符SLIV。
故,基于有效SLIV就能够确定TDRA表中会被调度的行索引。
可选地,所述根据TDRA表以及所述第一小区的第二集合,确定与所述第二集合中各个第一间隔对应的有效起止和长度指示符SLIV,包括:
基于TDRA表以及所述第一小区的第二集合,删除所述第一间隔对应的全部SLIV中冗余的SLIV;或者,
基于TDRA表以及所述第一小区的第二集合,挑选出所述第一间隔指示的PUCCH上反馈HARQ-ACK信息时对应的SLIV作为有效SLIV。
其中,基于TDRA表以及所述第一小区的第二集合,删除所述第一间隔对应的全部SLIV中冗余的SLIV,是基于第二集合中的第一间隔的值分析所有调度可能性所确定的。小区-3
例如,网络设备配置的多小区调度TDRA表如上表1所示,对于不支持单小区调度的小区-3,如表3所示,确定第二集合为{4,6,8,10,12}。
所以,基于该第二集合,所有调度的可能性如图2所示,这样,从TDRA表中删除的SLIV,以及保留下来的SLIV即集合R如下表8所示:
表8
又如网络设备配置的多小区调度TDRA表如上表1所示,支持单小区调 度的小区-3,如表2所示,确定第二集合为{2,4,6,8,10,12}。所以,基于该第二集合,所有调度的可能性如图3所示,这样,从TDRA表中删除的SLIV,以及保留下来的SLIV即集合R如下表9所示:
表9
该实施例中,可选地,一方面,基于TDRA表以及所述第一小区的第二集合,挑选出所述第一间隔指示的PUCCH上反馈HARQ-ACK信息时对应的SLIV作为有效SLIV,包括:
在第一小区不支持单小区调度的情况下,获取所述第一小区在各个行索引对应的调整后的第一集合;
若所述第一间隔属于第三行索引对应的调整后的第一集合,则由所述第三行索引的SLIV以及第四行索引的有效SLIV,确定所述第一间隔在所述第三行索引的有效SLIV;
其中,所述第四行索引为所述第三行索引的上一个行索引。
这里,由所述第三行索引的SLIV以及第四行索引的有效SLIV,确定所述第一间隔在所述第三行索引的有效SLIV,即,将所述第三行索引的SLIV以及第四行索引的有效SLIV的并集作为所述第一间隔在所述第三行索引的有效SLIV。
当然,若第三行索引为0,因不存在对应的第四行索引,此时,第一间隔属于第三行索引对应的调整后的第一集合,则r=0的有效SLIV即TDRA表中,第一小区在r=0时SLIV的值。
故,对于不支持单小区调度的第一小区,获取其在各个行索引对应的调整后的第一集合后,可以通过针对第一小区的第二集合中的一个第一间隔,遍历小区c对应的行索引,来分别确定这个第一间隔在各个行索引的有效 SLIV。当然,一个第一间隔在各个行索引的有效SLIV的并集,即这个第一间隔的有效SLIV。
如,对于第一小区的第二集合中的第一间隔如k1=4,假设该第一小区的行索引包括0和1,则通过遍历,在第三行索引为0时,判断k1=4是否属于r=0时的调整后的第一集合,若属于,则可以将TDRA表中,第一小区在r=0时SLIV的值作为k1=4且r=0的有效SLIV;在第三行索引为1时,判断k1=4是否属于r=1时的调整后的第一集合,若属于则可以将第一小区在k1=4且r=0的有效SLIV和TDRA表中第一小区在r=1时SLIV的值的并集作为第一小区在k1=4且r=1的有效SLIV。
这样,若小区-3不支持单小区调度,由表3所示,小区-3的第二集合为{4,6,8,10,12},且r=0时,调整的第一集合K1’0,3集合为{4,6,8};r=1时,调整的第一集合K1’1,3集合为{8,10,12}。因此,按照上述方式可得小区-3的第二集合中各个第一间隔的有效SLIV即集合Rk1如下表10所示:
表10
该实施例中,可选地,另一方面,基于TDRA表以及所述第一小区的第二集合,挑选出所述第一间隔指示的PUCCH上反馈HARQ-ACK信息时对应的SLIV作为有效SLIV,包括:
在第一小区支持单小区调度的情况下,获取所述第一小区在各个行索引对应的调整后的第一集合;
根据所述第一集合和第五行索引对应的调整后的第一集合,确定所述第五行索引对应的第四集合;
若所述第一间隔属于所述第五行索引对应的第四集合,则由所述第五行索引的SLIV以及第六行索引的有效SLIV,确定所述第一间隔在所述第五行索引的有效SLIV;
其中,所述第六行索引为所述第五行索引的上一个行索引。
这里,根据所述第一集合和第五行索引对应的调整后的第一集合,确定所述第五行索引对应的第四集合,即,将所述第一集合和所述第五行索引对应的调整后的第一集合的并集作为所述第五行索引对应的第四集合。
具体的,小区c在行索引r对应第四集合可记为K1”r,c集合。其中,K1”r,c集合==K1集合∪K1’r,c集合。
这里,由所述第五行索引的SLIV以及第六行索引的有效SLIV,确定所述第一间隔在所述第五行索引的有效SLIV,即,将所述第五行索引的SLIV以及第六行索引的有效SLIV的并集作为所述第一间隔在所述第五行索引的有效SLIV。
当然,若第五行索引为0,因不存在对应的第六行索引,此时,第一间隔属于第五行索引对应的第四集合,则r=0的有效SLIV即TDRA表中,第一小区在r=0时SLIV的值。
故,对于支持单小区调度的第一小区,获取其在各个行索引对应的调整后的第一集合后,可以进一步得到各个行索引对应的第四集合,然后通过针对第一小区的第二集合中的一个第一间隔,遍历小区c对应的行索引,来分别确定这个第一间隔在各个行索引的有效SLIV。当然,一个第一间隔在各个行索引的有效SLIV的并集,即这个第一间隔的有效SLIV。
如,对于第一小区的第二集合中的第一间隔如k1=4,假设该第一小区的行索引包括0和1,则通过遍历,在第五行索引为0时,判断k1=4是否属于r=0时的第四集合,若属于,则可以将TDRA表中,第一小区在r=0时SLIV的值作为k1=4且r=0的有效SLIV;在第五行索引为1时,判断k1=4是否属于r=1时的第四集合,若属于则可以将第一小区在k1=4且r=0的有效SLIV和TDRA表中第一小区在r=1时SLIV的值的并集作为第一小区在k1=4且r=1的有效SLIV。
这样,若小区-3支持单小区调度,由表2所示,小区-3的第二集合为{2,4,6,8,10,12},且r=0时,调整的第一集合K1’0,3集合为{4,6,8};r=1时,调整的第一集合K1’1,3集合为{8,10,12}。因此,按照上述方式可得小区-3,在r=0时的第四集合K1”0,3集合为{2,4,6,8};在r=1时的第四集合K1”1,3集合为{2,4,6,8,10,12},则第二集合中各个第一间隔的有效SLIV即集合Rk1如下表11所示:
表11

还需要说明的是,上述基于TDRA表以及所述第一小区的第二集合,挑选出所述第一间隔指示的PUCCH上反馈HARQ-ACK信息时对应的SLIV作为有效SLIV的方式,适用于单小区调度的TDRA表的内容项和多小区调度的TDRA表的内容项相同的情况。若单小区调度的TDRA表的内容项和多小区调度的TDRA表的内容项不同,可选地,基于TDRA表以及所述第一小区的第二集合,挑选出所述第一间隔指示的PUCCH上反馈HARQ-ACK信息时对应的SLIV作为有效SLIV,包括:
在第一小区支持单小区调度的情况下,获取所述第一小区在各个行索引对应的调整后的第一集合;
若所述第一间隔属于第七行索引对应的调整后的第一集合,则由所述第七行索引的SLIV以及第八行索引的有效SLIV,确定所述第一间隔在所述第七行索引的有效SLIV;
若所述第一间隔还属于所述第一集合,则所述第一间隔的有效SLIV为所述第一间隔在遍历完成后的有效SLIV和所述第一小区支持单小区调度时对应的全部SLIV的并集;
其中,所述第八行索引为所述第七行索引的上一个行索引。
这里,由所述第七行索引的SLIV以及第八行索引的有效SLIV,确定所述第一间隔在所述第七行索引的有效SLIV,即,将所述第七行索引的SLIV以及第八行索引的有效SLIV的并集作为所述第一间隔在所述第七行索引的有效SLIV。
当然,若第七行索引为0,因不存在对应的第八行索引,此时,第一间隔属于第七行索引对应的调整后的第一集合,则r=0的有效SLIV即TDRA表中,第一小区在r=0时SLIV的值。
故,对于支持单小区调度的第一小区,获取其在各个行索引对应的调整后的第一集合后,可以遍历小区c对应的行索引,来分别确定这个第一间隔在各个行索引的有效SLIV。当然,一个第一间隔在各个行索引的有效SLIV 的并集,即这个第一间隔在遍历完成后有效SLIV。
如,对于第一小区的第二集合中的第一间隔如k1=4,假设该第一小区的行索引包括0和1,则通过遍历,在第七行索引为0时,判断k1=4是否属于r=0时调整后的第一集合,若属于,则可以将TDRA表中,第一小区在r=0时SLIV的值作为k1=4且r=0的有效SLIV;在第五行索引为1时,判断k1=4是否属于r=1时调整后的第一集合,若属于,则可以将第一小区在k1=4且r=0的有效SLIV和TDRA表中第一小区在r=1时SLIV的值的并集作为第一小区在k1=4且r=1的有效SLIV。之后,还需判断k1=4是否属于第一集合,若属于,则需取上述确定的有效SLIV以及该第一小区支持单小区调度时对应的全部SLIV的并集作为k1=4的有效SLIV。
一般而言,在PDSCH调度发送时,为提高PDSCH的接收可靠性,支持PDSCH重复发送,重复次数repetitionNum可以通过如下两种方法确定:
1:半静态配置重复次数:如基于小区配置的pdsch-AggregationFactor,表示PDSCH重复次数(每次重复占用相邻的时隙),如pdsch-AggregationFactor配置为2时,表示每做一次PDSCH调度,基站将在连续2个时隙中重复发送PDSCH;
2:动态指示重复次数:在配置TDRA表时,每个调度行引入repetitionNumber-r16参数,即TDRA表中的每个行索引,其重复次数不同。
因此,可选地,该实施例中,所述获取时域资源分配TDRA表中所述各小区对应的第二间隔,还包括:
针对各小区,分别执行:
获取TDRA表中第一小区对应的第二间隔以及所述第一小区的重复传输次数;
根据所述重复传输次数,更新所述第一小区的第二间隔。
其中,获取第一小区的重复传输次数的方式对应上述配置方式,在此不再赘述。
可选地,所述根据所述重复传输次数,更新所述第一小区对应的第二间隔,包括:
通过公式K′0=K0+repetitionNum-1,计算更新的第二间隔K′0
其中,K0表示更新前的第二间隔,repetitionNum表示重复传输次数。
例如,网络设备通过RRC配置多小区调度TDRA表,如下表12所示:
表12
该表12中rep代表repetitionNumber-r16;即相应PDSCH的重复次数repetitionNum。有上表配置了PDSCH调度的重复发送,不同的行索引,对应的重复次数不同。通过上述公式K′0=K0+repetitionNum-1计算更新的第二间隔,得到新的多小区调度TDRA表,如下表13所示:
表13
这样,之后可以按照更新第二间隔后的TDRA表进行后续处理。
应该了解的是,该实施例中,为了减少“多小区PDSCH调度”的HARQ-ACK码本复杂度,对于一个DCI调度多个小区PDSCH的场景,可以配置HARQ-ACK反馈绑定,将每个PDSCH的译码结果合并(如:比特与 操作),生成1或者2比特;比如:1个DCI调度了4个小区的PDSCH,所有PDSCH的译码和反馈信息绑定成1比特信息,结果如下表14所示:
表14
该表中,&表示比特与;另外对于绑定生成的反馈信息过程,也可以描述为:当所有参与绑定的PDSCH译码正确时,反馈ACK,否则反馈NACK。
对于上述情况,该实施例中,所述根据所述第二集合确定所述多个小区静态混合自动重传请求HARQ码本对应的PDSCH接收时机之后,还包括:
在配置HARQ-ACK反馈绑定的情况下,根据所述多个小区中最晚PDSCH接收时机的PDSCH,确定HARQ-ACK信息。
也就是说,在一个DCI调度多个小区的PDSCH时,终端只计算最晚调度PDSCH为接收时机,其它小区不用反馈。例如,如图4所示,DCI-1调度小区-1、小区-2、小区-3的PDSCH,分别为:
-小区-1的时隙(slot)3上的PD-1(PDSCH1);
-小区-2的时隙4上的PD-2(PDSCH2);
-小区-3的时隙7上的PD-3(PDSCH3)。
由于PD-3的时间域最晚,因此终端只把时隙7作为PDSCH的接收时机,并反馈三个PDSCH(PD-1/2/3)的HARQ-ACK的绑定数值。相应的,小区-1的时隙-3,小区-2的时隙-5不作为PDSCH的接收时机,即不反馈HARQ-ACK信息。
其中,若至少两个小区都是最晚的,则选择该至少两个小区中一个特定小区的PDSCH来确定HARQ-ACK信息。该特定小区可以是按照默认方式确定的,如小区标识最小或最大等等。
当然,网络设备可以配置“HARQ-ACK绑定”的生成比特数,比如范围为:1,2,4。若未配置HARQ-ACK反馈绑定,HARQ-ACK信息的确定也可采用上述方式。
作为一个可选地示例2,终端接收到DCI,该DCI调度小区-1,小区-2, 小区-3和小区-4的PDSCH,终端还接收到第一集合{2,4,6},则终端执行:
步骤1,接收基站通过RRC信令配置的TDRA表,如表15所示:
表15
其中,NULL表示对应SLIV无效。如对于表1,当行索引是2时,小区-3没有被调度,即可以理解为小区-3只配置了一个2行的TDRA表。
步骤2,根据基站配置的TDRA表和第一集合,确定PDSCH接收时机,并确定HARQ-ACK信息。此时,终端无需进行使用第二集合。
这里,对于支持单小区调度的小区,不使用上述确定的各个小区的第二集合,直接使用第一集合中的第一间隔进行PDSCH接收时机的判定,且TDRA表配置项保持不变。
这里,对于不支持单小区调度的小区,如小区c,能够由ΔK0,r,c=0确定其PDSCH调度最晚,则根据第一集合和该小区在各个行索引的有效SLIV集合,生成HARQ-ACK信息。
具体实现包括:
Step 1:其中,为空集;
Step2:遍历该小区在TDRA表的所有行索引,获取每个行索引对应的调整后的调整参数,如小区c的行索引r对应的调整参数ΔK0,r,c,ΔK0,r,c=max(K0,r,1,…,K0,r,n,…,K0,r,N)-K0,r,c。如果ΔK0,r,c等于0,更新的有效SLIV集合=上一行索引更新的有效SLIV集合∪TDRA表中小区c行索引r的全部SLIV。如果则小区c将使用网络设备配置的第一集合判定PDSCH接收时机。而遍历完成后,即r取最大值时更新的有效SLIV集合,用于计算在时隙中PDSCH接收时机的个数,从而生成反馈的 HARQ-ACK信息。
具体地,假设网络设备配置第一集合={2,4,6},则小区-1的各个行索引对应信息如下表16所示(由于表16是针对小区-1的,故省略c=1的标识):
表16
由表16,ΔK0,r,1不等于0,小区-1上不反馈HARQ-ACK信息。
假设网络设备配置第一集合={2,4,6},则小区-2的各个行索引对应信息如下表17所示(由于表17是针对小区-2的,故省略c=2的标识):
表17
由表17,ΔK0,1,2=0,小区-2上需反馈HARQ-ACK信息,且确定使用配置的第一集合{2,4,6}中的第一间隔判定PDSCH接收时机,使用{SLIV=6}计算在时隙中PDSCH接收时机的个数。
假设网络设备配置第一集合={2,4,6},则小区-4的各个行索引对应信息如下表18所示(由于表18是针对小区-4的,故省略c=4的标识):
表18
由表18,ΔK0,0,4=0,ΔK0,2,4=0,小区-4上需反馈HARQ-ACK信息,且确定使用配置的第一集合{2,4,6}中的第一间隔判定PDSCH接收时机,且使用{SLIV=4,SLIV=11}计算在时隙中PDSCH接收时机的个数。对于小区-4,调度的可能性如图5所示,如果终端收到该DCI,指示在时隙16上有HARQ-ACK反馈的PUCCH的资源。在小区-4上,终端在时隙14,时隙12,时隙10上,反馈绑定后的HARQ-ACK信息;一个时隙中PDSCH接收时机的TDRA集合为:SLIV=4,和SLIV=11。
在该示例中,网络设备可以通过高层信令配置用于计算特定小区的PDSCH接收时机的第一间隔的集合,然后计算该集合中每个对应元素的有效SLIV集合,用于计算在一个时隙中PDSCH接收时机个数;网络设备还可以通过高层信令配置用于计算特定小区的PDSCH接收时机的第一间隔的集合,以及配置该集合中每个对应元素的有效SLIV集合,用于计算在一个时隙中PDSCH接收时机个数。
还需要说明的是,网络设备可以配置小区的子载波间隔(Sub-carrier space,SCS),如15KHz/30KHz/60KHz/120KHz,以及480KHz/960KHz。为了便于表达,不同SCS也可以使用参数μ=0,1,2,3,5,6表示,SCS和参数μ的关系为:SCS=2μ*15KHz。
在上述实现,默认小区的各个SCS数值相同,各个SCS包括:
μPUCCH,表示传输PUCCH信道的上行小区的SCS(即:2μPUCCH*15KHz);
μPDCCH,表示发送调度信令(调度多个小区的PDSCH的DCI)的PDCCH信道的下行小区的SCS(即:2μPDCCH*15KHz);
μPDSCH1,表示用于计算k1定时的下行小区(第一小区)的SCS(即:2μPDSCH1*15KHz);该小区可能同时传输PDSCH;例如,在计算小区c的第二集合时,μPDSCH1表示小区c的SCS;
μPDSCH2,表示传输PDSCH的下行小区的SCS(即:2μPDSCH2*15KHz)。
然而,在实际小区配置和数据传输过程中,上述四种小区的SCS可能存在不同的情况,这就需要针对不同SCS的情况做一些处理。
可选地,该实施例中,所述根据获取的第二间隔,确定所述第一小区在TDRA表中各行索引对应的调整参数,包括:
根据传输PUCCH信道的上行小区的SCS、发送所述DCI的PDCCH信道的下行小区的SCS、所述第一小区的SCS和传输PDSCH的下行小区的SCS中的至少一者,确定所述调整参数。
下面描述当上述小区不同SCS时的处理方法:
情况1:μPUCCH=μUL,μPDCCH=μPDSCH1=μPDSCH2=μDL
其中,μUL表示上行小区的SCS,μDL表示下行被调度小区的SCS。在该情况1时,需修正计算小区的第二集合的过程中小区在行索引对应的调整参数,然后确定调整的第一集合。具体的,对于小区c的行索引r, 若修正后的调整参数为整数,则能够按照上述方式确定调整的第一集合,但修正后的调整参数存在非整数的情况。对于修正后的调整参数非整数的情况,通过即对修正后的调整参数向上取整得到第一值,将第一集合的元素分别与第一值相加得到集合A,并通过即对修正后的调整参数向下取整得到第二值,将第一集合的元素分别与第二值相加得到集合B;最终,取集合A和集合B的并集作为小区c在行索引r对应的调整的第一集合。表示1个上行时隙的时长中包括的下行时隙的个数。如下:
例子1:μUL=2,μDL=0,即上行SCS=60KHz,下行SCS=15KHz;则1个上行时隙包含4个下行时隙;此时:ΔK0,r,c的数值要做整数倍乘(倍乘因子为:1个上行时隙包含调度小区下行时隙的个数);
例子2:μUL=0,μDL=2,即上行SCS=15KHz,下行SCS=16KHz;则1个上行时隙包含1/4个下行时隙;此时:ΔK0,r,c的数值要做分数倍乘(倍乘因子为:1个上行时隙包含调度小区下行时隙的个数)。其中,当分数倍乘存在小数部分时,需要进行上取整,和下取整,并做并集;以适应基站灵活调度的目标。
情况2:μPUCCH=μUL,(μPDSCH1=μ1)<(μPDSCH2=μ2);
在该情况2时,需重新计算小区的第二集合的过程中小区在行索引对应的调整参数,然后确定调整的第一集合。具体的,对于小区c的行索引r,令max(K0,r,1,…,K0,r,n,…,K0,r,N)=K01,r,c,K0,r,c=K02,r,c,通过ΔK0,r,c=(K01,r,c+1)*2μ2-μ1-(K02,r,c+1)计算小区c在行索引r对应的调整参数 ΔK0,r,c。其中,表示小区c(当前调度小区)一个时隙中,包含计算k1定时的小区的时隙个数。例如,如图6所示,对于计算小区-1和小区-2上的K0差值,由于不同小区的SCS不同,需要在计算差值中进行修正。小区-1的K0=2,小区-2的K0=4,则通过ΔK0,r,c=(K01,r,c+1)*2μ2-μ1-(K02,r,c+1)=(1+2)*4-(4+1)=7,计算出的差值结果为7,符合实际情况。
情况3:μPUCCH=μUL,(μPDSCH1=μ1)>(μPDSCH2=μ2);
在该情况3时,需重新计算小区的第二集合的过程中小区在行索引对应的调整参数,然后确定调整的第一集合。具体的,对于小区c的行索引r,令max(K0,r,1,…,K0,r,n,…,K0,r,N)=K01,r,c,K0,r,c=K02,r,c,通过 计算小区c在行索引r对应的调整参数ΔK0,r,c。其中,表示小区c(当前调度小区)一个时隙中,包含计算k1定时的小区的时隙个数。此时,因μ1>μ2倍乘因子后,会出现小数(非整数)的情况,需要进行下取整。例如,如图7所示,对于计算小区-1和小区-2上的K0差值,由于不同小区的SCS不同,需要在计算差值中进行修正。小区-1的K0=10,小区-2的K0=0,则通过计算出的差值结果为2,符合实际情况。
情况4:μPUCCH=μ0
发送调度信令信道的PDCCH和被调度小区的SCS不同,终端计算K0位置时需要根据SCS的不同进行补偿,如m是发送DCI(调度信令)所处的时隙编号,对于1个DCI调度多个小区上的PDSCH,当多个被调度小区的SCS不同时,上述通过ΔK0,r,c=max(K0,r,1,…,K0,r,n,…,K0,r,N)-K0,r,c确定实际调度过程中,不同小区的PDSCH所在时隙的差值,会出现不准确的现象;所以,需重新计算小区的第二集合的过程中小区在行索引对应的调整参数,然后确定调整的第一集合,包括:
方法一:约束μPDCCH的数值,使其SCS均不大于(小于或等于)被调度小区的SCS。即μPDCCH小于或等于μPDSCH,μPDSCH表示被调度小区的SCS;
此时,2μPDSCH是2μPDCCH的整数倍,也就是说,的结果是整数;
以上述情况2(μPDSCH1=μ1)<(μPDSCH2=μ2)为例,将新的第二间 隔代入ΔK0,r,c=(K01,r,c+1)*2μ2-μ1-(K02,r,c+1),得出 即消除了μPDCCH对计算ΔK0,r,c的影响。
以上述情况3(μPDSCH1=μ1)>(μPDSCH2=μ2)为例,将新的第二间隔代入得出 即消除了μPDCCH对计算ΔK0,r,c的影响。
方法二:根据不同SCS的组合,计算出多个ΔK0,r,c
该方法,遍历可能发送调度信令小区的SCS;并遍历m数值,从0到2μPDCCH-1;然后计算出多个可能ΔK0,r,c
以上述情况2(μPDSCH1=μ1)<(μPDSCH2=μ2)为例,ΔK0,r,c的增量变化ΔKPDCCH为:
ΔKPDCCH表示ΔK0,r,c不一样的增量可能性。
遍历可能发送调度信令小区的SCS;遍历m数值,从0到2μPDCCH-1;然后计算出多个可能ΔK0,r,c,即
假设μ1=1,μ2=2,μPDCCH=3,μPDCCH=2,K01,r,c=5,K02,r,c=1,则可以得到ΔKPDCCH如下表19(μPDCCH=3)所示:
表19

由表19可以看出ΔKPDCCH=3={0,-1}。
还可以得到ΔKPDCCH如下表20(μPDCCH=2)所示:
表20
由表20可以看出ΔKPDCCH=2={0,-1}。
则,遍历后的ΔKPDCCH=2,3={0,-1}。
可以计算: 如此,将{8,9}替代{9}进行第二集合的确定。
以上述情况3(μPDSCH1=μ1)>(μPDSCH2=μ2)为例,ΔK0,r,c的增量变化ΔKPDCCH为:
遍历可能发送调度信令小区的SCS;遍历m数值,从0到2μPDCCH-1;然后计算出多个可能ΔK0,r,c,即
假设μ1=2,μ2=1,μPDCCH=3,μPDCCH=2,K01,r,c=5,K02,r,c=1,则可以得到ΔKPDCCH如下表21(μPDCCH=3)所示:
表21
由表21可以看出ΔKPDCCH=3={0}。
还可以得到ΔKPDCCH如下表22(μPDCCH=2)所示:
表22
由表22可以看出ΔKPDCCH=2={0}。
则,遍历后的ΔKPDCCH=2,3={0}。
可以计算: 如此,将ΔK0,r,c={1}进行第二集合的确定。
综上,本申请实施例的方法,给出了多小区调度场景下,静态HARQ-ACK反馈计算PDSCH接收时机的方法,使得基于静态HARQ-ACK码本的反馈机制有效执行。
如图8所示,本申请实施例的一种混合自动重传反馈方法,由终端执行,包括:
步骤801,接收DCI,所述DCI调度多个小区的PDSCH,所述DCI指示在调度的各小区的PDSCH中最晚被调度PDSCH与PUCCH之间的时隙数;
步骤802,根据第二间隔确定所述DCI调度的各小区的静态HARQ码本对应的PDSCH接收时机;其中,所述第二间隔用于表示DCI与PDSCH之间的时隙数。
通过上述步骤801-802,终端在接收DCI后,由该DCI调度多个小区的PDSCH,能够利用第二间隔确定DCI调度的各小区的静态HARQ码本对应的PDSCH接收时机,从而实现一个DCI调度多个小区上的PDSCH情况下的混合自动重传反馈。
可选地,所述第二间隔是TDRA表中记录的,且所述TDRA表的每个行索引下对应所述多个小区的第二间隔相同。
也就是说,终端确定所述多个小区静态HARQ码本对应的PDSCH接收时机使用的第二间隔,是TDRA表中的第二间隔,而且,该TDRA表的每个行索引下对应所述多个小区的第二间隔相同。例如TDRA表如下表23所示:
表23
表23中,行索引0,4个配置小区的K0均为2;行索引1,4个配置小 区的K0均为1;行索引2,3个配置小区的K0均为3;小区-3中的NULL表示没有被调度。
需要说明的是,使用TDRA表(该TDRA表的每个行索引下对应所述多个小区的第二间隔相同)中的第二间隔确定所述多个小区静态HARQ码本对应的PDSCH接收时机的方法,适用于多小区调度PDSCH时,单独配置TDRA表,相关针对每个小区的调度时域信息(包括:行索引个数,SLIV内容,K0内容),可以和单小区调度配置的TDRA表内容不一样的场景。
而该TDRA表可以是网络设备主动下发的;或者,终端上报信息表示希望网络设备配置TDRA表,该TDRA表的每个行索引下对应所述多个小区的第二间隔相同。
可选地,所述第二间隔是TDRA表中记录的特定第二间隔,或者特定小区的第二间隔。
这里,特定第二间隔可以是默认第二间隔,特定小区的第二间隔可以是默认小区的第二间隔。
例如,TDRA表如下表24所示:
表24
假设默认小区是第一个调度的PDSCH小区,若使用第一个调度的PDSCH小区的第二间隔,则表24中:
行索引0,调度了4个小区的PDSCH,其中小区-1是被调度小区的最小ID数值的小区,即第一个调度的PDSCH小区,则小区-2、小区-3、小区-4对应的时域信息的K0均和小区-1的K0保持相同,也就是说所有调度小区的K0=2;
行索引1,调度了4个小区的PDSCH,其中小区-1的是被调度小区的最 小ID数值的小区,即第一个调度的PDSCH小区,则小区-2、小区-3、小区-4对应的时域信息的K0均和小区-1的K0保持相同,也就是说所有调度小区的K0=1;
行索引2,调度了2个小区的PDSCH,其中小区-2的是被调度小区的最小ID数值的小区,即第一个调度的PDSCH小区,则小区-4对应的时域信息的K0均和小区-2的K0保持相同,也就是说两个调度小区的K0=3。
需要说明的是,使用TDRA表中记录的特定第二间隔,或者特定小区的第二间隔,来确定所述多个小区静态HARQ码本对应的PDSCH接收时机的方法,适用于多小区调度PDSCH时,不用单独配置TDRA表的场景。
还需要说明的是,当TDRA表中,每行指示的K0不同时,也可取默认数值,如:调度小区中的最小K0或者最大K0,最后一个被调度小区(小区ID最大数值)对应的K0,或者第一个被调度小区(小区ID最小数值)对应的K0等等;这里不做限定。
另外,这里的K0数值可以是接收的调度信令(例如DCI)与接收到的PDSCH的起始位置之间的时隙间隔(即现有K0的定义),也可以是接收的调度信令与接收到的PDSCH的结束位置之间的时隙间隔,即当基站指示或者配置重复传输时,终端可以将接收到的调度信令(例如DCI)到最后一次PDSCH传输(若配置重复传输,最后一次是指重复传输的最后一次传输)的时隙间隔数作为K0(即K0=K0+repetitionNum-1)。
需要说明的是,所述TDRA表的每个行索引下对应所述多个小区的第二间隔相同,其目的是保证多个被调度小区的PDSCH结束位置的时隙相同(如果配置重复传输的话,所有被调度小区最后一次传输PDSCH的时隙位置相同),从而避免扩展K1序列数值,减少协议和终端实现的复杂度。
在本申请的一个实施例中,为了保证所有被调度小区最后一次传输PDSCH的时隙位置相同,当被调度小区支持重复传输时,需要对重复次数或者各小区确定的K0进行调整。
下面详细描述如何对重复次数或者各小区确定的K0进行调整。
A、调整各个被调度小区的重复次数repetitionNum,使得调整后的各个被调度小区的重复次数相同。采用的具体方法包括但不限于:
方法1:如果被调度小区配置了重复传输,即传输次数repetitionNum>1,当调度信令是多小区调度时,终端确定基站指示的传输次数repetitionNum=1。
具体地,终端确定重复传输次数的配置/指示无效,或者默认传输次数为1。(需要说明的是,传输次数大于1的配置或者指示,仅仅在单载波调度中生效)。
方法2:当基站的调度信令为多小区调度时,基站单独配置重复传输次数,该重复传输次数的数值作用于所有被调度小区。
方法3:对于所有被调度小区的重复传输次数,根据特定被调度小区的指示或者配置参数确定,例如:约定该特定小区可以是被调度小区中的小区编号最小、或者小区编号最大的小区;或者是重复传输次数最小,或者重复传输次数最大的小区。这里不做限制。
B、确定各个被调度小区K0,使得被调度小区的K0与确定的参考小区的K0相同。所述方法包括但不限于以下几种:
首先,确定参考小区以及该参考小区的K0。
具体地,假设参考小区的重复传输次数为ref_N(其中,N取值大于等于1,当N等于1时表示只传输1次);参考小区的K0为ref_K0(K0的取值大于等于0)。
其次,针对每个被调度小区(假设为X),基站调度或者指示的重复传输次数x_N(其中,x_N的取值大于等于1,若取值等1时表示只传输1次),那么确定被调度小区的DCI信令与PDSCH数据传输位置时隙间隔为x_k0,具体分为以下两种情况:
情况一:确定接收到被调度小区的DCI信令与第一次接收PDSCH数据的传输位置的时隙间隔为x_k0。若被调度小区为X,那么x_k0=ref_K0+ref_N–x_N。
即:调度的PDSCH数据第一次传输所在时隙为:ref_K0+ref_N–x_N,最后一次传输在:ref_K0+ref_N–1。
情况二:确定接收到被调度小区的DCI信令与最后一次接收PDSCH数据的传输位置的时隙间隔为x_k0。若被调度小区X,,那么x_k0=ref_K0–x_N +1。
即调度的PDSCH数据第一次传输所在时隙为:ref_K0–x_N+1,最后一次传输在:ref_K0。
其中,这里记载的“第一次接收PDSCH数据”和“最后一次接收PDSCH数据”可以理解为重复传输的第一次和最后一次。
另外,终端执行如图1所示方法流程还是执行如图8所示方法流程,可以由网络设备指示。
如图9所示,本申请实施例还提供了一种混合自动重传反馈方法,由网络设备执行,包括:
步骤901,发送DCI,所述DCI调度多个小区的PDSCH,所述DCI指示在调度的各小区的PDSCH中最晚被调度PDSCH与PUCCH之间的时隙数;
步骤902,确定第一集合;其中,所述第一集合中包含第一间隔,所述第一间隔用于表示PDSCH与PUCCH之间的时隙数;
