在本申请实施例中,不同的PDSCH承载的传输块相同或不同,因此,下文中“多个PDSCH”或“至少两个PDSCH”可以指承载相同或不同传输块的不同PDSCH。更具体的,不同的PDSCH承载的传输块可能对应相同或不同的HARQ进程,其中,不同的HARQ进程有不同的HARQ进程标识。
在一些实施例中,PDSCH时域资源分配(TDRA)表(或者简称为TDRA表)包括至少一行,以下,为方便描述,将一行称为一个PDSCH TDRA配置(或者简称为TDRA配置),即PDSCH TDRA表包括至少一个PDSCH TDRA配置。一个PDSCH TDRA配置包括至少一个PDSCH时域资源配置(或者简称为时域资源配置),PDSCH时域资源配置中至少包括时隙中的符号位置(起始符号+长度)配置;另外,一个PDSCH TDRA配置还可以包括至少一个时隙偏移K0配置,该K0表示PDSCH与PDCCH的时隙偏移,K0配置包括在PDSCH时域资源配置中或者不包括在PDSCH时域资源配置中;该一个PDSCH TDRA配置还可以包括其他信息(例如,映射类型,mapping type),且该其他信息包括在PDSCH时域资源配置中或者不包括在PDSCH时域资源配置中,本申请实施例并不以此作为限制。其中,关于时隙中的符号位置配置,其例如包括start and length indicator SLIV,该SLIV对应起始符号(S)和长度(L)的有效组合(valid combination),或者,其例如对应起始符号starting symbol配置和长度length配置,该starting symbol配置和length配置是有效组合。
混合自动重传请求(Hybrid Automatic Repeat reQuest,HARQ),是一种结合前向纠 错(Forward Error Correction,FEC)与自动重传请求(Automatic Repeat reQuest,ARQ)方法的技术。FEC通过添加冗余信息,使得接收端能够纠正一部分错误,从而减少重传的次数。对于FEC无法纠正的错误,接收端会通过ARQ机制请求发送端重发数据。接收端使用检错码,通常为循环冗余校验(Cyclic Redundancy Check,CRC),来检测接收到的数据包是否出错。如果无错,则接收端会发送一个肯定的确认(ACK)给发送端,发送端收到ACK后,会接着发送下一个数据包。如果出错,则接收端会丢弃该数据包,并发送一个否定的确认(NACK)给发送端,发送端收到NACK后,会重发相同的数据。
在NR中,需要对DCI调度的一个或多个PDSCHs(全部或部分)进行HARQ-ACK反馈,例如终端设备可以生成HARQ-ACK码本,该HARQ-ACK码本包括半静态码本(Type-1HARQ-ACK codebook)和动态码本(Type-2HARQ-ACK codebook)。终端根据RRC信令配置采用Type-1HARQ-ACK codebook或Type-2HARQ-ACK codebook。
以下结合各个实施例说明在支持HARQ进程被配置或指示了HARQ反馈禁用或反馈使能的情况下,如何生成或是否生成或如何发送上述半静态码本和/或动态码本。
第一方面的实施例
本申请实施例提供一种信息反馈方法,从终端设备侧进行说明。
图2是本申请实施例的信息反馈方法的一示意图,如图2所示,该方法包括:
201,终端设备接收用于调度物理下行共享信道(PDSCH)的至少一个下行控制信息(DCI),所述DCI调度一个或多个PDSCHs,其中,所述一个或多个PDSCH中包括至少一个对应的HARQ进程是反馈使能的或是反馈禁用的PDSCH;
202,该终端设备发送针对一个或多个PDSCHSs的HARQ反馈信息。
在一些实施例中,该终端设备接收调度一个或多个PDSCHs的下行控制信息(DCI),该DCI可以(能够)调度多个PDSCHs,但实际上可能调度了一个PDSCH或多个PDSCHs,另外,在本申请实施例中,多个PDSCH可以是时域上调度多个PDSCH也可以是频域上调度多个PDSCH,也可以是时域和频域上的多个PDSCH。例如,时域上调度多个PDSCH时该DCI应用的PDSCH时域资源分配表支持通过一个DCI调度多个PDSCHs,本申请实施例并不以此作为限制。
在一些实施例中,在201中,该DCI和PDSCH在相同载波(小区)或不同载波(小区)发送,也就是说,PDSCH可以是由同一载波(小区)上的DCI调度的,或者是由不同载波(小区)上的DCI调度的。在该DCI和PDSCH在不同载波(小区)的情况下,根据被调度的载波(小区)对应的配置(e.g.HARQ process数,HARQ反馈使能/禁用配置,PDSCH时域资源分配表配置等)调度该PDSCH。
图36A是DCI和调度的PDSCH在同一载波(carrier)/小区同一BWP示意图,如图14所示,(a)对应调度一个PDSCH(不限制DCI是只能调度一个还是可以调度多个,b)对应时域上调度多个PDSCH,PDSCH按时域顺序索引,c)对应频域上调度多个PDSCH,PDSCH按频域顺序索引,d)对应时域和频域上调度多个,PDSCH按先频域后时域顺序索引,e)对应时域和频域上调度多个,PDSCH按先时域后频域顺序索引。
图36B是DCI和调度的PDSCH在同一载波/小区不同BWP示意图,如图15所示,(a)对应调度一个PDSCH(不限制DCI是只能调度一个还是可以调度多个,b)对应时域上调度多个PDSCH,PDSCH按时域顺序索引,c)对应频域上调度多个PDSCH,PDSCH按频域顺序索引,d)对应时域和频域上调度多个,PDSCH按先频域后时域顺序索引,e)对应时域和频域上调度多个,PDSCH按先时域后频域顺序索引。
图36C是DCI和调度的PDSCH在不同载波/小区(跨载波调度)示意图,如图16所示,(a)对应调度一个PDSCH(不限制DCI是只能调度一个还是可以调度多个,b)对应时域上调度多个PDSCH,PDSCH按时域顺序索引,c)对应频域上调度多个PDSCH,PDSCH按频域顺序索引,d)对应时域和频域上调度多个,PDSCH按先频域后时域顺序索引,e)对应时域和频域上调度多个,PDSCH按先时域后频域顺序索引。
图36D是DCI调度多个PDSCH示意图,如图17所示,a)对应调度时域不同的两个PDSCH,该两个PDSCH在不同载波/小区的不同BWP上,在同一载波/小区的同一BWP上仅调度一个PDSCH,PDSCH按时域顺序索引,b)对应调度频域不同的两个PDSCH,该两个PDSCH在不同载波/小区的不同BWP上,在同一载波/小区的同一BWP上仅调度一个PDSCH,PDSCH按频域顺序索引,c)对应调度4个PDSCH,在不同载波/小区的不同BWP上分别调度两个PDSCH,在同一载波/小区的同一BWP 上调度两个PDSCH,PDSCH按先频域后时域顺序索引,d)对应调度4个PDSCH,在不同载波/小区的不同BWP上分别调度两个PDSCH,在同一载波/小区的同一BWP上调度两个PDSCH,PDSCH按先时域后频域顺序索引。以下以DCI可以在时域上调度多个PDSCH为例进行说明。
以下以DCI可以在时域上调度多个PDSCH为例进行说明。
在一些实施例中,为了支持DCI可以在时域上调度多个PDSCH,该DCI应用的PDSCH时域资源分配表支持通过一个DCI调度多个PDSCHs。为方便说明,以下先对该PDSCH时域资源分配配置进行进一步说明。
在一些实施例中,用于支持通过一个DCI调度多个PDSCHs的PDSCH TDRA表包括至少一个用于支持通过一个DCI调度多个PDSCHs的PDSCH TDRA配置。同时,该表中可以包括或不包括用于支持通过一个DCI调度一个PDSCH的PDSCH TDRA配置。例如,该PDSCH TDRA表包括至少一个(M个)PDSCH TDRA配置(至少一行),在M个PDSCH TDRA配置中有至少一个(P个)用于支持通过一个DCI调度多个PDSCHs的PDSCH TDRA配置,包括M-P个用于支持通过一个DCI调度一个PDSCH的PDSCH TDRA配置。其中,M大于或等于P,M和P都是大于或等于1的整数。
在一些实施例中,用于支持通过一个DCI调度多个PDSCHs的PDSCH TDRA配置包括至少两个PDSCH时域资源配置(例如至少两个SLIV,每个SLIV与一个PDSCH对应)。
在一些实施例中,用于支持通过一个DCI调度一个PDSCH的PDSCH TDRA配置仅包括一个PDSCH时域资源配置。
在一些实施例中,该方法还可以包括:(未图示)该终端设备可以根据第一列表确定各DCI应用的PDSCH时域资源分配表,从而确定该第一分配表,该第一列表的一列对应所述的用于配置用于支持通过一个DCI调度多个PDSCHs的PDSCH TDRA表的第一指示信息(e.g.pdsch-TimeDomainAllocationListForMultiPDSCH)。该第一指示信息例如包括在PDSCH-Config中。即终端设备根据该第一列表从预定义的或通过高层信令配置的PDSCH时域资源分配(TDRA)表中确定各DCI应用的PDSCH时域资源分配表。
例如,该第一列表用于确定格式为DCI format 1_1或DCI format 1_2的DCI应 用的PDSCH时域资源分配表,不用于确定格式为DCI format 1_0的DCI应用的PDSCH时域资源分配表,例如格式为DCI format 1_0的DCI可以使用第二列表来确定DCI应用的PDSCH TDRA表,该第二列表包括的内容例如和现有针对DCI format1_0和DCI format 1_1的列表(Applicable PDSCH time domain resource allocation for DCI formats 1_0and 1_1)相同。即,格式为DCI format 1_0和DCI format 1_1的DCI应用的PDSCH TDRA表基于不同的列表确定。
例如,该第一列表与第二列表的不同之处之一在于,该第一列表还包括一列,该一列对应用于配置用于支持通过一个DCI调度多个PDSCHs的PDSCH TDRA表的第一指示信息(e.g.pdsch-TimeDomainAllocationListForMultiPDSCH),而该第二列表中不包括对应用于配置用于支持通过一个DCI调度多个PDSCHs的PDSCH TDRA表的第一指示信息的列。换句话说,该第二列表在确定DCI应用的PDSCH TDRA表时,不考虑用于支持通过一个DCI调度多个PDSCHs的PDSCH TDRA表第一指示信息,因此,基于第二列表确定的该DCI应用的PDSCH时域资源分配表不可能是用于支持通过一个DCI调度多个PDSCHs的PDSCH时域资源分配表,基于该第一列表确定的该DCI应用的PDSCH时域资源分配表可以是用于支持通过一个DCI调度多个PDSCHs的PDSCH时域资源分配表。
在一些实施例中,该DCI的格式是DCI format 1_1或DCI format 1_2,该DCI应用的PDSCH TDRA表与加扰该DCI的循环冗余校验CRC的无线网络临时标识RNTI无关。例如,在RNTI是小区无线网络临时标识,(Cell-RadioNetworkTemporaryIdentifier,C-RNTI),编码调制方案C-RNTI(MCS-C-RNTI),配置调度RNTI(CS-RNTI)时,该DCI应用的PDSCH TDRA表相同。下表1是该第一列表的一个示例表,该表1中的列PDSCH-ConfigCommon includes pdsch-TimeDomainAllocationList,PDSCH-Config includes pdsch-TimeDomainAllocationList分别对应用于配置cell-specific和UE-specific的用于仅支持通过一个DCI调度一个PDSCH的PDSCH TDRA表的第二指示信息(即PDSCH-ConfigCommon中的pdsch-TimeDomainAllocationList和PDSCH-Config中的pdsch-TimeDomainAllocationList),具体含义可以参考现有技术,此处不再赘述。其中,根据表1,针对在不与CORESET 0关联的公共搜索空间(或者说关联的CORESET不是CORESET 0的公共搜索空间)或UE专用搜索空间发送DCI,在配置了用于支 持通过一个DCI调度多个PDSCH的PDSCH TDRA表的情况下(也就是说,在PDSCH-Config中包括用于配置该PDSCH TDRA表的第一指示信息(pdsch-TimeDomainAllocationListForMultiPDSCH)的情况下),该DCI在采用C-RNTI、MCS-C-RNTI或CS-RNTI加扰时都应用该用于支持通过一个DCI调度多个PDSCH的PDSCH TDRA表。
表1

在一些实施例中,该DCI的格式是DCI format 1_1或DCI format 1_2,该DCI在采用不同RNTI加扰时应用的PDSCH时域资源分配表不同。例如,在采用CS-RNTI加扰时应用的PDSCH时域资源分配表与采用非CS-RNTI(C-RNTI或MCS-C-RNTI)加扰时应用的PDSCH时域资源分配表不同。
例如,该DCI由非CS-RNTI(C-RNTI或MCS-C-RNTI)加扰的情况下,该DCI应用的PDSCH时域资源分配表是用于支持通过一个DCI调度多个PDSCHs的PDSCH时域资源分配表;在该DCI由CS-RNTI加扰时,该DCI应用的PDSCH时域资源分 配表不是用于支持通过一个DCI调度多个PDSCHs的PDSCH时域资源分配表,换句话说,该DCI由CS-RNTI加扰时,该DCI应用的PDSCH时域资源分配表仅是支持通过一个DCI调度一个PDSCH的PDSCH TDRA表。
或者说,在该DCI在由CS-RNTI加扰时,该DCI应用的PDSCH时域资源分配表不是该第一指示信息配置的PDSCH时域资源分配表;在该DCI由非CS-RNTI(C-RNTI或MCS-C-RNTI)加扰时,该DCI应用的PDSCH时域资源分配表是该第一指示信息配置的PDSCH时域资源分配表,由于用于SPS激活的DCI必须是被CS-RNTI加扰的,因此即使第一指示信息配置了支持通过一个DCI调度多个PDSCHs的PDSCH TDRA表,也不能用于SPS激活。
下表2-1和2-2是该第一列表示例表,与表1不同之处在于,在采用CS-RNTI加扰时应用的PDSCH时域资源分配表与采用非CS-RNTI(C-RNTI或MCS-C-RNTI)加扰时应用的PDSCH时域资源分配表不同,另外,在表2-1中,第一指示信息配置需要同时支持仅通过一个DCI调度一个PDSCH的PDSCH TDRA表和通过一个DCI调度多个PDSCHs的的PDSCH TDRA表,即使在第一指示信息配置了用于支持通过一个DCI调度多个PDSCHs的PDSCH TDRA表时,RNTI是CS-RNTI的DCI可以应用用于仅支持通过一个DCI调度一个PDSCH的PDSCH TDRA表,在表2-2中,第一指示信息配置不需要同时支持仅通过一个DCI调度一个PDSCH的PDSCH TDRA表和通过一个DCI调度多个PDSCHs的的PDSCH TDRA表,在第一指示信息配置了用于支持通过一个DCI调度多个PDSCHs的PDSCH TDRA表而没有通过第一指示信息配置用于仅支持通过一个DCI调度一个PDSCH的PDSCH TDRA表时,RNTI是CS-RNTI的DCI format 1_1可以应用预定义的PDSCH TDRA表。
表2-1
Figure PCTCN2021122477-appb-000002
表2-2
Figure PCTCN2021122477-appb-000003
在一些实施例中,该DCI的格式是DCI format 1_1或DCI format 1_2,该DCI在 用于SPS激活和/或SPS重传时(该DCI的CRC是由CS-RNTI加扰的)应用的PDSCH时域资源分配表和在用于非SPS激活和/或SPS重传时(该DCI的CRC是不是由CS-RNTI加扰的)应用的PDSCH时域资源分配表不同。
例如,在该DCI用于SPS激活和/或SPS重传时,该DCI应用的PDSCH时域资源分配表不是用于支持通过一个DCI调度多个PDSCHs,换句话说,该DCI用于SPS激活和/或SPS重传时,该DCI应用的PDSCH时域资源分配表仅是支持通过一个DCI调度一个PDSCH的PDSCH TDRA表;在该DCI用于非SPS激活和/或SPS重传时,该DCI应用的PDSCH时域资源分配表是用于支持通过一个DCI调度多个PDSCHs。
或者说,在该DCI用于SPS激活和/或SPS重传时,该DCI应用的PDSCH时域资源分配表不是该第一指示信息配置的PDSCH时域资源分配表;在该DCI用于非SPS激活和/或SPS重传时,该DCI应用的PDSCH时域资源分配表是该第一RRC信令配置的PDSCH时域资源分配表。
如上所述,在表1,2-1,2-2中,第一指示信息配置用于支持通过一个DCI调度多个PDSCHs的PDSCH TDRA表,即pdsch-TimeDomainAllocationListForMultiPDSCH的值是YES,第一指示信息配置用于不支持通过一个DCI调度多个PDSCHs的PDSCH TDRA表,即pdsch-TimeDomainAllocationListForMultiPDSCH的值是NO。
在一些实施例中,该第一列表用于确定格式为DCI format 1_1的DCI应用的PDSCH时域资源分配表,也可以用于确定格式为DCI format 1_0的DCI应用的PDSCH时域资源分配表,例如可以将前述示例中的表格看作第三列表与现有的第二表格合并作为第一表格,同时用于确定格式为DCI format 1_1和DCI format 1_0的DCI应用的PDSCH时域资源分配表。
在一些实施例中,该DCI包括第二信息域,该第二信息域可以是时域资源分配域Time domain resource assignment,该第一信息域通过指示该DCI应用的PDSCH TDRA表中PDSCH TDRA配置对应的索引(行索引,e.g.行索引的值大于或等于1)来指示PDSCH时域资源,换句话说,该DCI通过指示其应用的PDSCH TDRA表中的PDSCH TDRA配置来调度PDSCH。例如,该DCI的第二信息域的值m(假设m为大于或等于0的整数)对应指示该DCI应用的PDSCH TDRA表中索引为m+1(也就是第m+1行)的PDSCH TDRA配置。在该PDSCH TDRA表是第一指示信息配置的情况下,例如,该第一指示信息配置的第m+1个PDSCH TDRA配置对应的索引值 为m+1,也就是说,第二信息域的值为m时,其对应的是第一RRC信令配置的第m+1个PDSCH TDRA配置。
在一些实施例中,在201中,在DCI(例如DCI中的第二信息域)指示的PDSCH TDRA配置是用于支持通过一个DCI调度多个PDSCH的PDSCH TDRA配置(包括多个PDSCH时域资源配置)时,UE可以根据该PDSCH TDRA配置包括的分别对应多个PDSCHs的PDSCH时域资源配置确定调度的多个PDSCHs时域资源。
在一些实施例中,该DCI还可以包括第三信息域,该第三信息域用于指示HARQ进程标识,其中,调度的不同PDSCH对应相同或不同的HARQ进程,终端设备可以根据该DCI确定该DCI指示的HARQ进程以及确定调度的PDSCH的HARQ进程。

在一些实施例中,终端设备可以根据该指示信息和该DCI确定该DCI调度的一个或多个PDSCHs对应的HARQ进程是HARQ反馈禁用或是HARQ反馈使能的,例如,根据该指示信息和/或由DCI承载的使能/禁用指示信息确定DCI指示的HARQ进程,以及确定指示的HARQ进程是反馈使能还是反馈禁用,然后确定该DCI调度的PDSCH对应的HARQ进程,进而确定调度的PDSCH对应的HARQ进程是反馈使能还是反馈禁用,其中,该一个或多个PDSCHs包括至少一个对应的HARQ进程是反馈使能的或是反馈禁用的PDSCH。
在一些实施例中,该方法还可以包括(未图示):该终端设备接收一个或多个PDSCHs,例如终端设备可以从时隙n-N+1到时隙n上接收PDSCHs,在202中,在时隙n+k1上使用上行资源(PUCCH或PUSCH)发送针对一个或多个PDSCHSs的HARQ反馈信息。k1的值可以由该DCI指示或者由高层信令指示,该k1含义以及指示方式可以根据根据现有技术确定。该HARQ反馈信息包含在HARQ-ACK码本中。换句话说,在接收了多个DCI的情况下,该多个DCI(或者说该多个DCI调度的PDSCH)的HARQ-ACK反馈的时域位置(例如时隙n+k1)相同。
在一些实施例中,该HARQ-ACK码本可以是半静态码本,关于该半静态码本的大小以及生成方式可以参考现有技术,此处不再一一赘述,该半静态码本中至少包含 针对一个或多个PDSCHs的HARQ反馈信息,以下仅说明在不同场景下如何确定该一个或多个PDSCHs的HARQ反馈信息。
需要说明的是,本申请实施例中DCI调度的PDSCH可以指该DCI指示的PDSCH TDRA配置对应的PDSCH(配置PDSCH),也可以指该DCI实际调度的PDSCH(实际PDSCH),本申请并不以此作为限制。例如,该实际PDSCH可以是满足第一条件的配置PDSCH,或者该实际PDSCH可以等同于该配置PDSCH,在一些实施例中,上该第一条件可以是与半静态配置的传输方向(或者说用于半静态配置传输方向的信息)和/或配置的PRACH资源和/或用于动态调度上行传输的信息和/或用于动态配置传输方向的信息有关的条件,例如该实际PDSCH可以是不包括被半静态配置的传输方向为上行的符号的配置PDSCH,或者说该实际PDSCH可以是有对应HARQ进程的配置PDSCH,此处不再一一举例。也就是说,在本申请实施例中,“DCI调度的PDSCH”与“DCI调度的配置PDSCH”,“DCI实际调度的PDSCH”,“DCI调度的时机PDSCH”,“DCI调度的PDSCH中的实际PDSCH”的表述可以互换。“HARQ反馈信息”与“HARQ-ACK信息”的表述可以互换。
在一些实施例中,在终端设备没有配置或激活SPS时,或者说不考虑终端设备是否配置或激活SPS,在该DCI调度的PDSCH中包括对应HARQ进程是反馈禁用的第二PDSCH时,该第二PDSCH对应的HARQ反馈信息与该第二PDSCH的解码结果无关,或该第二PDSCH对应的HARQ反馈信息与该第二PDSCH的解码结果相关。该第二PDSCH对应的HARQ反馈信息与该第二PDSCH的解码结果无关也可以表示忽略第二PDSCH的解码结果,而将该第二PDSCH对应的HARQ反馈信息设为NACK。也就是说,即使第二PDSCH解码成功(接收成功),该第二PDSCH对应的HARQ反馈信息仍设为NACK。其中,该第二PDSCH可以是一个或多个,由于该第二PDSCH对应HARQ进程是反馈禁用的,也就是说,终端设备是可以不发送针对该HARQ进程的第二PDSCH的HARQ反馈信息,这时,可以无需考虑该第二PDSCH的实际解码结果,而直接该第二PDSCH对应的HARQ反馈信息设置为NACK。
在一些实施例中,在终端设备没有配置或激活SPS时,或者说不考虑终端设备是否配置或激活SPS,在该DCI调度的PDSCH中包括对应HARQ进程是反馈使能的第一PDSCH时,该第一PDSCH对应的HARQ反馈信息与该第一PDSCH的解码结果相关。其中,该第一PDSCH可以是一个或多个,由于该第一PDSCH对应HARQ 进程是反馈使能的,也就是说,终端设备需要发送针对该HARQ进程的第一PDSCH的HARQ反馈信息,这时,需要考虑该第一PDSCH的实际解码结果,在解码成功(接收成功)时,将第一PDSCH对应的HARQ反馈信息设置为ACK,在解码失败(接收失败)时,将第一PDSCH对应的HARQ反馈信息设置为NACK。
在一些实施例中,在该终端设备还被配置或激活了SPS,且该SPS的PDSCH(SPS PDSCH)对应的HARQ进程是HARQ反馈禁用时,该SPS PDSCH和该第二PDSCH对应的HARQ反馈信息确定方式相同或不同,该第一PDSCH对应的HARQ反馈信息与该第一PDSCH的解码结果相关(在解码成功(接收成功)时,将第一PDSCH对应的HARQ反馈信息设置为ACK,在解码失败(接收失败)时,将第一PDSCH对应的HARQ反馈信息设置为NACK)。其中,该SPS PDSCH对应的HARQ进程可以使用如下公式(1)或(2)确定::
HARQ Process ID=[floor(CURRENT_slot×10/(numberOfSlotsPerFrame×periodicity))]modulo nrofHARQ-Processes         公式(1)
HARQ Process ID=[floor(CURRENT_slot×10/(numberOfSlotsPerFrame×periodicity))]modulo nrofHARQ-Processes+harq-ProcID-Offset       公式(2)
其中,CURRENT_slot等于[(SFN×numberOfSlotsPerFrame)+slot number in the frame],其中,numberOfSlotsPerFrame是一个系统帧包括的时隙的数量,nrofHARQ-Processes是HARQ进程数量,harq-ProcID-Offset是HARQ进程标识偏移(例如是相对于HARQ进程标识0的偏移),包含在SPS配置信息SPS-Config中。对于没有被配置harq-ProcID-Offset的情况,与下行传输的开始时隙相关联的HARQ进程标识可以采用公式(1)确定,对于配置了harq-ProcID-Offset的情况,与下行传输的开始时隙相关联的HARQ进程标识可以采用公式(2)确定。另外,在用于激活SPS的DCI调度多个PDSCHs时,SPS PDSCH的HARQ进程标识还与DCI调度的PDSCH的数量和/或PDSCH时域资源在该DCI调度的至少两个PDSCHs时域资源中的序号有关,具体可以参考现有技术,此处不再一一赘述。另外,在支持配置HARQ进程是反馈使能或反馈禁用的情况下,还需要根据HARQ进程是反馈使能或反馈禁用来确定SPS PDSCH对应的HARQ进程,例如0~harq-ProcID-Offset范围内的HARQ进程标识对应的HARQ进程都是HARQ反馈使能,或者都是HARQ反馈禁用的,此处不再一一举例。
例如,该SPS PDSCH和该第二PDSCH对应的HARQ反馈信息确定方式相同包括:该SPS PDSCH对应的HARQ反馈信息与该SPS PDSCH的解码结果无关,即忽略SPS PDSCH的解码结果,将SPS PDSCH对应的HARQ反馈信息设为NACK,且该第二PDSCH对应的HARQ反馈信息与该第二PDSCH的解码结果无关,即忽略第二PDSCH的解码结果,将第二PDSCH对应的HARQ反馈信息设为NACK,也就是说,即使第二PDSCH和SPS PDSCH解码成功(接收成功),该第二PDSCH和SPS PDSCH对应的HARQ反馈信息仍设为NACK。或该SPS PDSCH对应的HARQ反馈信息与该SPS PDSCH的解码结果相关,且该第二PDSCH对应的HARQ反馈信息与该第二PDSCH的解码结果相关,也就是,在SPS PDSCH解码成功(接收成功)时,将SPS PDSCH对应的HARQ反馈信息设置为ACK,在SPS PDSCH解码失败(接收失败)时,将SPS PDSCH对应的HARQ反馈信息设置为NACK,在第二PDSCH解码成功(接收成功)时,将第二PDSCH对应的HARQ反馈信息设置为ACK,在第二PDSCH解码失败(接收失败)时,将第二PDSCH对应的HARQ反馈信息设置为NACK。
例如,该SPS PDSCH和该第二PDSCH对应的HARQ反馈信息确定方式不同包括:该SPS PDSCH对应的HARQ反馈信息与该SPS PDSCH的解码结果相关,且该第二PDSCH对应的HARQ反馈信息与该第二PDSCH的解码结果无关,即忽略第二PDSCH的解码结果,将第二PDSCH对应的HARQ反馈信息设为NACK(即使第二PDSCH解码成功(接收成功),该第二PDSCH对应的HARQ反馈信息仍设为NACK),也就是,在SPS PDSCH解码成功(接收成功)时,将SPS PDSCH对应的HARQ反馈信息设置为ACK,在SPS PDSCH解码失败(接收失败)时,将SPS PDSCH对应的HARQ反馈信息设置为NACK,但该第二PDSCH对应的HARQ反馈信息始终为NACK;或该SPS PDSCH对应的HARQ反馈信息与该SPS PDSCH的解码结果无关,即忽略SPS PDSCH的解码结果,将SPS PDSCH对应的HARQ反馈信息设为NACK(即使SPS PDSCH解码成功(接收成功),该SPS PDSCH对应的HARQ反馈信息仍设为NACK),且该第二PDSCH对应的HARQ反馈信息与该第二PDSCH的解码结果相关,也就是,在第二PDSCH解码成功(接收成功)时,将第二PDSCH对应的HARQ反馈信息设置为ACK,在第二PDSCH解码失败(接收失败)时,将第二PDSCH对应的HARQ反馈信息设置为NACK,但该SPS PDSCH对应的HARQ反馈信息始 终为NACK。
在一些实施例中,将对应HARQ进程是反馈使能的PDSCH称为第一PDSCH,将对应HARQ进程是反馈禁用的PDSCH称为第二PDSCH,第一PDSCH和/或第二PDSCH可以是上述配置PDSCH或实际PDSCH,或者说,该第一PDSCH和/或第二PDSCH有对应的HARQ进程。在201中,该至少一个DCI包括第一DCI和/或第二DCI和/或第三DCI,该第一DCI调度多个PDSCHs,且该多个PDSCHs包括至少一个第一PDSCH和至少一个第二PDSCH;该第二DCI调度多个PDSCHs(或可以调度多个PDSCHs),且该多个PDSCHs都是第二PDSCH,或该第二DCI仅调度一个PDSCH(仅可以调度一个PDSCH),该一个PDSCH是第二PDSCH;该第三DCI调度多个PDSCHs(或可以调度多个PDSCHs),且该多个PDSCH都是第一PDSCH,或该第三DCI调度一个PDSCH(仅可以调度一个PDSCH),该一个PDSCH是第一PDSCH。
在一些实施例中,在201中,终端设备可以仅接收一个或多个第一DCI,或者仅接收一个或多个第二DCI或者仅接收一个或多个第三DCI,或者除了接收至少一个第一DCI或至少一个第二DCI外,还接收到至少一个第三DCI,以下分别对接收到不同DCI的情况说明如何确定该一个或多个PDSCHs的HARQ反馈信息。

在一些实施例中,在该终端设备被配置或激活了SPS,且该SPS的PDSCH(SPS PDSCH)对应的HARQ-ACK进程是HARQ反馈使能,且仅接收到至少一个该第一DCI或仅接收到至少一个该第二DCI或仅接收到至少一个该第三DCI时,或者,在该终端设备被配置或激活了SPS,且该SPS PDSCH对应的HARQ-ACK进程是HARQ反馈使能,且接收到至少一个该第一DCI和/或接收到至少一个该第二DCI,还接收到至少一个第三DCI时,

值得注意的是,以上附图2仅对本申请实施例进行了示意性说明,但本申请不限于此。例如可以适当地调整各个操作之间的执行顺序,此外还可以增加其它的一些操作或者减少其中的某些操作。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。
以上各个实施例仅对本申请实施例进行了示例性说明,但本申请不限于此,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,可以在支持HARQ反馈使能/禁用这一HARQ机制的情况下发送HARQ反馈信息;因此,可以减少上行控制信令开销,同时,网络设备无需等待终端设备上报HARQ反馈信息即可发送新数据,进而可以降低数据传输时延。
第二方面的实施例
图3是本申请实施例的信息反馈方法的一示意图,应用于终端设备侧,如图3所示,该方法包括:
301,该终端设备接收的第四下行控制信息(DCI),该第四DCI包括累计下行分配指示(counter downlink assignment indicator,C-DAI)信息和/或总DAI(total downlink assignment indicator,C-DAI)信息;
302,该终端设备根据该累计DAI信息和/或总DAI信息确定HARQ反馈信息。
在一些实施例中,该第四DCI可以用于调度PDSCH,该DCI调度的PDSCH包括对应的HARQ进程是反馈使能的或是反馈禁用的PDSCH。该第四DCI可以调度一个或多个PDSCH;DCI调度一个PDSCH,该DCI应用的PDSCH时域资源分配表仅支持通过一个DCI调度一个PDSCH;或者,该DCI调度一个或多个PDSCHs,该DCI应用的PDSCH时域资源分配表支持通过一个DCI调度多个PDSCHs,关于其具体实施方式可以参考第一方面的实施例,此处不再赘述,但本申请实施例并不以此作为限制,例如该第四DCI还可以用于调度PUSCH(一个或多个PUSCHs),或者该第四DCI不调度数据传输,此处不再一一举例,该第四DCI的格式可以是1_0或1_1,具体可以参考现有技术。
在一些实施例中,该第四DCI包括C-DAI和/或T-DAI,在传统方法中,C-DAI表示以{服务小区,PDCCH监控时机}对表示的累计接收到的与DCI格式1_1/1_0相关联的PDSCH或者SPS PDSCH释放数量,累计个数的统计顺序为:先按服务小区索引升序,再按PDCCH监控时机索引升序。T-DAI值表示{服务小区,PDCCH监控时机}对的总数,相同PDCCH监控时机上的所有服务小区的T-DAI相同,T-DAI随着PDCCH监控时机索引更新,C-DAI表示,T-DAI表示,图4是传统方法C-DAI和T-DAI示意图,如图4所示,在第一个PDCCH监控时机上,服务小区1和3上接收到的DCI中包括C-DAI和T-DAI,在服务小区2上接收到的DCI中包括C-DAI,其中,T-DAI的值为3,各个服务小区上的C-DAI按照服务小区索引升序排列;在第二个PDCCH监控时机上,服务小区1上接收到的DCI中包括C-DAI和T-DAI,在服务小区3上接收到的DCI中包括C-DAI,其中,T-DAI的值为5,服务小区1和3上的C-DAI按照服务小区索引升序排列,也就是说,传统方法中,在C-DAI和T-DAI计数时,没有考虑是否支持HARQ进程可以被指示或配置为反馈使能或者反馈禁用,或者说,没有考虑DCI调度的PDSCH是否包含对应HARQ进程是反馈禁用或者反馈使能的PDSCH。
为了支持HARQ进程可以被指示或配置为反馈使能或者反馈禁用,在本申请实施例中,提出了一种与传统方法不同的C-DAI和T-DAI计数以及统计方法,在C-DAI和T-DAI计数时,需要考虑DCI调度的PDSCH是否包含对应HARQ进程是反馈禁用或者反馈使能的PDSCH,该累计DAI信息和/或所述总DAI信息针对用于调度 PDSCH的DCI以DCI为粒度计数和/或以PDSCH为粒度计数,以下分别进行说明C-DAI和T-DAI计数以及统计方法以及各方法下如何根据该累计DAI信息和/或总DAI信息确定HARQ反馈信息。
(一)以DCI为粒度计数
在一些实施例中,可以参与计数的DCI可以包括实际接收到调度PDSCH的DCI,也可以包括漏检(没有接收到的)的(用于调度或不用于调度PDSCH)DCI,也可以包括激活SPS的DCI,也可以包括实际接收的包括了与上行冲突的PDSCH的DCI,但可以参与计数的DCI需要包括至少一个有对应HARQ进程的DCI,以下为方便说明,各示例图中DCI调度的PDSCH是指有对应HARQ进程的PDSCH,该说明同样适用于后述(二)。
图28A至图28C是以DCI为粒度计数的C-DAI和T-DAI示意图,如图28A至图28C所示,发送DCI调度的PDSCH对应的HARQ反馈信息的上行资源(时域位置)相同,如图28A所示,C-DAI和T-DAI以实际接收到的DCI为粒度进行计数,如图28B所示,与图28A不同之处在于,漏检(没有接收到的)的(用于调度或不用于调度PDSCH)DCI也参与计数,如图28C所示,包括至少一个有上行冲突的PDSCH的DCI也参与计数。
在一些实施例中,在可以参与计数的DCI中,该C-DAI和/或T-DAI针对用于调度PDSCH的DCI仅计入调度的PDSCH中包含至少一个对应的HARQ进程是反馈使能的PDSCH的DCI。该C-DAI和/或T-DAI不统计调度的PDSCH中仅包含对应的HARQ进程是反馈禁用的PDSCH的DCI。需要说明的是,前述DCI是泛指的DCI,并不特指301中的第四DCI。
例如,针对用于调度PDSCH的第四DCI,该第四DCI调度的PDSCH中包括至少一个对应的HARQ进程是反馈使能的第一PDSCH和至少一个对应的HARQ进程是反馈禁用的第二PDSCH,该C-DAI和/或T-DAI统计该第四DCI,或者说在计数时,计入该第四DCI。该第四DCI中C-DAI和/或T-DAI表示的含义与现有类似,此处不再重复。
图5是以DCI为粒度计数的C-DAI和T-DAI示意图,如图5所示,与图4不同之处在于,第一个PDCCH监控时机上服务小区1接收的DCI调度的PDSCH中包括1个第二PDSCH,但由于该DCI调度的PDSCH还包括3个第一PDSCH,因此,该 DCI也被C-DAI和/或T-DAI计入,即在第一个PDCCH监控时机上,服务小区1和3上接收到的DCI中包括C-DAI和T-DAI,在服务小区2上接收到的DCI中包括C-DAI,其中,T-DAI的值为3,各个服务小区上的C-DAI按照服务小区索引升序排列;在第二个PDCCH监控时机上,服务小区1上接收到的DCI中包括C-DAI和T-DAI,在服务小区3上接收到的DCI中包括C-DAI,其中,T-DAI的值为5,服务小区1和3上的C-DAI按照服务小区索引升序排列。
在上述实施例中,终端设备根据该累计DAI信息和/或总DAI信息确定HARQ反馈信息包括:该第四DCI调度的PDSCH对应的HARQ过程是反馈使能的第一PDSCH对应的HARQ反馈信息与该第一PDSCH的解码结果相关,该第四DCI调度的PDSCH中对应的HARQ进程是反馈禁用的第二PDSCH对应的HARQ反馈信息与该第二PDSCH的解码结果无关,即忽略该第二PDSCH的实际解码结果,将该第二PDSCH对应的HARQ反馈信息设为NACK,在第一PDSCH解码成功(接收成功)时,将第一PDSCH对应的HARQ反馈信息设置为ACK,在第一PDSCH解码失败(接收失败)时,将第一PDSCH对应的HARQ反馈信息设置为NACK。
或者,该第四DCI调度的PDSCH对应的HARQ过程是反馈使能的第一PDSCH对应的HARQ反馈信息与该第一PDSCH的解码结果相关,该第四DCI调度的PDSCH中对应的HARQ进程是反馈禁用的第二PDSCH对应的HARQ反馈信息与该第二PDSCH的解码结果相关,即在第一PDSCH解码成功(接收成功)时,将第一PDSCH对应的HARQ反馈信息设置为ACK,在第一PDSCH解码失败(接收失败)时,将第一PDSCH对应的HARQ反馈信息设置为NACK;在第二PDSCH解码成功(接收成功)时,将第二PDSCH对应的HARQ反馈信息设置为ACK,在第二PDSCH解码失败(接收失败)时,将第二PDSCH对应的HARQ反馈信息设置为NACK。
例如,针对用于调度PDSCH的第四DCI,该第四DCI调度的PDSCH都是第一PDSCH,该C-DAI和/或T-DAI统计该第四DCI,或者说在计数时,计入该第四DCI。该第四DCI中C-DAI和/或T-DAI表示的含义与现有类似,此处不再重复。如图4所示,各个PDCCH监控时机上各个服务小区接收的DCI调度的PDSCH中仅包括一个或多个第一PDSCH,不包括第二PDSCH,因此,各个DCI都被C-DAI和/或T-DAI计入,即在第一个PDCCH监控时机上,服务小区1和3上接收到的DCI中包括C-DAI和T-DAI,在服务小区2上接收到的DCI中包括C-DAI,其中,T-DAI的值为3,各个 服务小区上的C-DAI按照服务小区索引升序排列;在第二个PDCCH监控时机上,服务小区1上接收到的DCI中包括C-DAI和T-DAI,在服务小区3上接收到的DCI中包括C-DAI,其中,T-DAI的值为5,服务小区1和3上的C-DAI按照服务小区索引升序排列。
在上述实施例中,终端设备根据该累计DAI信息和/或总DAI信息确定HARQ反馈信息包括:该第四DCI调度的第一PDSCH对应的HARQ反馈信息与该第一PDSCH的解码结果相关,在第一PDSCH解码成功(接收成功)时,将第一PDSCH对应的HARQ反馈信息设置为ACK,在第一PDSCH解码失败(接收失败)时,将第一PDSCH对应的HARQ反馈信息设置为NACK。
例如,针对用于调度PDSCH的第四DCI,该第四DCI调度的PDSCH都是第二PDSCH,该C-DAI和/或T-DAI不统计该第四DCI,或者说在计数时,不计入该第四DCI。对于该第四DCI中的C-DAI和/或T-DAI可以是接收到的DCI(该DCI调度PDSCH中包括至少一个第一PDSCH)的累计个数,例如C-DAI和/或T-DAI可以等于该第四DCI接收的PDCCH监控时机为止的各监控时机的各个服务小区上接收到的DCI(该DCI调度PDSCH中包括至少一个第一PDSCH)的总数。
图6是以DCI为粒度计数的C-DAI和T-DAI示意图,如图6所示,与图4不同之处在于,第一个PDCCH监控时机上服务小区1接收的DCI调度的PDSCH中仅包第二PDSCH,不包括第一PDSCH,因此,该DCI不被C-DAI和/或T-DAI计入,即在第一个PDCCH监控时机上,服务小区2和3上接收到的DCI中包括C-DAI和T-DAI,其中,T-DAI的值为2,各个服务小区上的C-DAI按照服务小区索引升序排列;在第二个PDCCH监控时机上,服务小区1和3上接收到的DCI中包括C-DAI和T-DAI,其中,T-DAI的值为4,服务小区1和3上的C-DAI按照服务小区索引升序排列。
图7是以DCI为粒度计数的C-DAI和T-DAI示意图,如图7所示,与第一个PDCCH监控时机上服务小区1接收的DCI中调度的PDSCH中仅包第二PDSCH,不包括第一PDSCH,因此,该DCI不被C-DAI和/或T-DAI计入,与图6不同之处在于,该DCI(第四DCI)中可以包括T-DAI,T-DAI可以等于该第一PDCCH监控时机上个各个服务小区上接收到的DCI(该DCI调度PDSCH中包括至少一个第一PDSCH)的总数2。
图8是以DCI为粒度计数的C-DAI和T-DAI示意图,如图8所示,与第一个 PDCCH监控时机上服务小区1接收的DCI中调度的PDSCH中仅包第二PDSCH,不包括第一PDSCH,因此,该DCI不被C-DAI和/或T-DAI计入,与图7不同之处在于,该DCI(第四DCI)中还可以包括C-DAI。C-DAI可以等于该第一PDCCH监控时机上个各个服务小区上接收到的DCI(该DCI调度PDSCH中包括至少一个第一PDSCH)的总数2。
在上述实施例中,由于该第四DCI调度的都是第二PDSCH,因此,不需要生成针对所述第二PDSCH的HARQ反馈信息。
需要说明的是,上述图5至图8仅与图28A中的场景结合说明如何以DCI为粒度进行计数,但图5至图8也可以与图28B至图28C中的场景结合,此处不再一一赘述。
在上述实施例中,在终端设备接收多个DCI后,使用与上述第四DCI调度的PDSCH相同的方法之一确定各DCI调度的PDSCH的HARQ反馈信息后,可以生成动态码本,该动态码本中包括X个PDSCH的HARQ反馈信息,X等于最后一个接收到的DCI中的T-DAI值,某个DCI调度的PDSCH的HARQ反馈信息排列在动态码本的第Y个位置,Y等于该DCI中C-DAI的值,即终端设备将该HARQ反馈信息包含在码本中在确定的用于发送HARQ反馈信息的时域位置进行发送,关于该时域位置将在后述进行说明;另外,在考虑SPS PDSCH的情况,或者在支持编码块组情况,该动态码本的生成方式可以参考现有技术,此处不再一一赘述。
(二)以PDSCH为粒度计数
在一些实施例中,可以参与计数的PDSCH可以包括实际接收到调度PDSCH的DCI调度的PDSCH,也可以包括漏检(没有接收到的)的(用于调度或不用于调度PDSCH)DCI调度的PDSCH,也可以包括实际接收的包括了与上行冲突的PDSCH的DCI调度的其他不与上行冲突的PDSCH,但可以参与计数的DCI调度的PDSCH需要有对应HARQ进程。
图29A至图29C是以PDSCH为粒度计数的C-DAI和T-DAI示意图,如图29A至图29C所示,发送DCI调度的PDSCH对应的HARQ反馈信息的上行资源(时域位置)相同,如图29A所示,C-DAI和T-DAI以实际接收到的DCI调度的PDCCH为粒度进行计数,如图29B所示,与图29A不同之处在于,漏检(没有接收到的)的(用于调度或不用于调度PDSCH)DCI调度的PDSCH也可以参与计数,如图29C 所示,与图29A不同之处在于,调度包括至少一个与上行冲突的PDSCH的DCI调度的其他PDSCH也可以参与计数。
图30A至图30C是以PDSCH为粒度计数的C-DAI和T-DAI示意图,如图30A至图30C所示,发送DCI调度的PDSCH对应的HARQ反馈信息的上行资源(时域位置)相同,与图29A至图29C的不同之处在于,在一个DCI调度多个PDSCHs时,图29A至图29C中的C-DAI指示该DCI调度的最后一个PDSCH对应的序号,而图30A至图30C中的C-DAI指示该DCI调度的第一个PDSCH对应的序号。以下仅以C-DAI指示该DCI调度的最后一个PDSCH对应的序号为例进行说明。
在一些实施例中,在可以参与计数的PDSCH中,该C-DAI和/或T-DAI针对DCI调度的PDSCH仅统计对应的HARQ进程是反馈使能的PDSCH。该累计DAI信息和/或所述总DAI信息不统计对应的HARQ进程是反馈禁用的PDSCH。需要说明的是,前述DCI是泛指的DCI,并不特指301中的第四DCI。通过以PDSCH为粒度计数,在使用动态码本反馈HARQ-ACK信息时,可以减少码本大小,降低资源开销。
例如,针对用于调度PDSCH的第四DCI,该第四DCI调度的PDSCH中包括至少一个对应的HARQ进程是反馈使能的第一PDSCH和至少一个对应的HARQ进程是反馈禁用的第二PDSCH,该C-DAI和/或T-DAI统计该第四DCI调度的第一PDSCH,或者说在计数时,计入该第四DCI调度的第一PDSCH。该第四DCI中的C-DAI和/或T-DAI可以等于该第四DCI接收的PDCCH监控时机为止的各监控时机的各个服务小区上接收到的第一PDSCH的累计数。
图9是以PDSCH为粒度计数的C-DAI和T-DAI示意图,如图9所示,第一个PDCCH监控时机上服务小区1接收的DCI调度的PDSCH中包括1个第二PDSCH,但由于该DCI调度的PDSCH还包括3个第一PDSCH,该第四DCI中仅3个第一被C-DAI和/或T-DAI计入,即在第一个PDCCH监控时机上,服务小区1和3上接收到的DCI中包括C-DAI和T-DAI,在服务小区2上接收到的DCI中包括C-DAI,其中,T-DAI的值为6,各个服务小区上的C-DAI按照服务小区索引升序排列;在第二个PDCCH监控时机上,服务小区1上接收到的DCI中包括C-DAI和T-DAI,在服务小区3上接收到的DCI中包括C-DAI,其中,T-DAI的值为9,服务小区1和3上的C-DAI按照服务小区索引升序排列。
在上述实施例中,终端设备根据该累计DAI信息和/或总DAI信息确定HARQ反 馈信息包括:该第四DCI调度的第一PDSCH的解码结果相关,在第一PDSCH解码成功(接收成功)时,将第一PDSCH对应的HARQ反馈信息设置为ACK,在第一PDSCH解码失败(接收失败)时,将第一PDSCH对应的HARQ反馈信息设置为NACK。也就是说,不需要生成第二PDSCH的HARQ反馈信息。
例如,针对用于调度PDSCH的第四DCI,该第四DCI调度的PDSCH都是第一PDSCH,该C-DAI和/或T-DAI统计该第四DCI调度的各个第一PDSCH,或者说在计数时,计入该第四DCI调度的各个第一PDSCH。该第四DCI中的C-DAI可以等于该第四DCI接收的PDCCH监控时机为止的调度的第一PDSCH的当前累计数,该第四DCI中的T-DAI可以等于该第四DCI接收的PDCCH监控时机为止的各监控时机的各个服务小区上接收到的第一PDSCH的总数。
图10是以PDSCH为粒度计数的C-DAI和T-DAI示意图,如图10所示,由于各个监控时机对应的各个服务小区上接收的DCI都仅调度第一PDSCH,因此各个第一PDSCH都被C-DAI和/或T-DAI计入,即在第一个PDCCH监控时机上,服务小区1~3上接收到的DCI中包括C-DAI和T-DAI,其中,T-DAI的值为7,C-DAI的值依次为5,6,7;在第二个PDCCH监控时机上,服务小区1和3上接收到的DCI中包括C-DAI和T-DAI,其中,T-DAI的值为10,服务小区1和3上的C-DAI依次为9和10。
在上述实施例中,终端设备根据该累计DAI信息和/或总DAI信息确定HARQ反馈信息包括:该第四DCI调度的第一PDSCH的解码结果相关,在第一PDSCH解码成功(接收成功)时,将第一PDSCH对应的HARQ反馈信息设置为ACK,在第一PDSCH解码失败(接收失败)时,将第一PDSCH对应的HARQ反馈信息设置为NACK。也就是说,由于该第四DCI不包括第二PDSCH,因此不需要生成第二PDSCH的HARQ反馈信息。
例如,针对用于调度PDSCH的第四DCI,该第四DCI调度的PDSCH都是第二PDSCH,该C-DAI和/或T-DAI不统计该第四DCI调度的所有第二PDSCH,或者说在计数时,不计入该第四DCI调度的所有第二PDSCH。该第四DCI中的C-DAI和/或T-DAI可以等于该第四DCI接收的PDCCH监控时机为止的各监控时机的各个服务小区上接收到的第一PDSCH的累计数。
图11是以PDSCH为粒度计数的C-DAI和T-DAI示意图,如图11所示,由于第 四DCI都仅调度第二PDSCH,因此该第四DCI调度的第二PDSCH都不被C-DAI和/或T-DAI计入,即在第一个PDCCH监控时机上,服务小区2~3上接收到的DCI中包括C-DAI和T-DAI,其中,T-DAI的值为3,C-DAI的值依次为1,3;在第二个PDCCH监控时机上,服务小区1和3上接收到的DCI中包括C-DAI和T-DAI,其中,T-DAI的值为6,服务小区1和3上的C-DAI依次为5,6,在第一个PDCCH监控时机上,服务小区1上接收到的DCI中包括T-DAI为2。
在上述实施例中,由于该第四DCI调度的都是第二PDSCH,因此,不需要生成针对所述第二PDSCH的HARQ反馈信息。
在上述实施例中,在终端设备接收多个DCI后,使用与上述第四DCI调度的PDSCH相同的方法之一确定各DCI调度的PDSCH的HARQ反馈信息后,可以生成动态码本,该动态码本中包括X个PDSCH的HARQ反馈信息,X等于最后一个接收到的DCI中的T-DAI值,某个DCI调度的PDSCH的HARQ反馈信息排列在动态码本的第Y个位置,Y等于该DCI中C-DAI的值,即终端设备将该HARQ反馈信息包含在码本中在确定的用于发送HARQ反馈信息的时域位置进行发送,关于该时域位置将在后述进行说明;另外,在考虑SPS PDSCH的情况,或者在支持编码块组情况,该动态码本的生成方式可以参考现有技术,此处不再一一赘述。
在一些实施例中,上述(一)和(二)中的方法可以单独执行,也可以结合执行,本申请实施例并不以此作为限制。
在一些实施例中,在该第四DCI调度的PDSCH都是第二PDSCH时,该第四DCI中的C-DAI和/或T-DAI为特定值。
例如,只接收到调度的(一个或多个)PDSCH对应HARQ process是反馈禁用的第四DCI(一个或多个),但有漏检(没有接收到的)的(用于调度或不用于调度PDSCH)DCI(例如根据接收到的DCI中的C-DAI/T-DAI确定)时,也需要发送HARQ反馈信息,该HARQ反馈信息包含的信息比特均为NACK。该第四DCI中的C-DAI和/或T-DAI设置一个特定值,e.g.0,而不需要根据调度情况改变(不需要根据其他DCI的数量或其他DCI调度的PDSCH数量改变)。
在一些实施例中,该方法还可以包括(未图示):该终端设备接收一个或多个PDSCHs,例如终端设备可以从时隙n-N+1到时隙n上接收PDSCHs,该方法还可以包括:
该终端设备在该接收的PDSCH对应的用于发送HARQ反馈信息的时域位置发送该HARQ反馈信息。
在一些实施例中,该终端设备根据所述DCI调度的最后一个对应HARQ反馈使能的HARQ进程的PDSCH所在时域位置确定用于发送所述HARQ反馈信息的时域位置。
例如,该终端设备根据所述DCI调度的最后一个对应HARQ反馈使能的HARQ进程的PDSCH所在时域位置和HARQ反馈定时确定用于发送所述DCI调度的PDSCH的HARQ反馈信息的时域位置,该HARQ反馈定时k指示所述DCI调度的最后一个对应HARQ反馈使能的HARQ进程的PDSCH所在时域位置和发送所述DCI调度的PDSCH的HARQ反馈信息的时域位置之间的时域偏移。如,该时域位置可以是时隙和/或符号。由此,可以进一步降低反馈时延。
图12和图13是该发送HARQ反馈信息的时域位置示意图,如图12和13所示,该时域位置时隙n+k与该DCI调度的最后一个对应HARQ-ACK反馈使能的HARQ进程的PDSCH所在时域位置时隙n的偏移等于HARQ反馈定时k,k的值可以由该DCI指示或者由高层信令指示。
例如,该第四DCI包括第一信息域,该第一信息域用于指示该HARQ反馈定时,或者,该方法还包括:(未图示)
该终端设备接收高层信令,该高层信令用于指示该HARQ反馈定时k。
关于k的承载方式可以参考现有技术,此处不再赘述,在接收了多个DCI的情况下,该多个DCI(或者说该多个DCI调度的PDSCH)的HARQ-ACK反馈的时域位置(例如时隙n+k)相同。
在一些实施例中,确定DCI调度的PDSCH是第一PDSCH还是第二PDSCH的方法可以参考第一方面的实施例,此处不再赘述。
由上述实施例可知,可以在支持HARQ反馈使能/禁用这一HARQ机制的情况下发送HARQ反馈信息;因此,可以减少上行控制信令开销,同时,网络设备无需等待终端设备上报HARQ反馈信息即可发送新数据,进而可以降低数据传输时延。
第三方面的实施例
本申请实施例提供一种信息反馈方法,从终端设备侧说明,其中,与第一或第二 方面的实施例的重复部分不再赘述。
图14是本申请实施例的信息接收方法的一示意图,如图14所示,该方法包括:
1401,该终端设备接收PDSCH,该PDSCH对应的HARQ进程是反馈禁用的;
1402,该终端设备不在该PDSCH对应的用于发送HARQ反馈码本的时域位置发送HARQ反馈码本。
在一些实施例中,在1401中,该PDSCH可以是DCI调度的一个或多个PDSCHs中的PDSCH,也可以是SPS PDSCH,在该PDSCH是DCI调度的一个或多个PDSCHs中的PDSCH时,例如,该DCI调度多个PDSCHs,终端设备接收调度的多个PDSCHs的一个或部分或全部PDSCH,换句话说,1401中接收该PDSCH中的多个PDSCH由同一DCI调度的,本申请实施例并不以此作为限制,确定该PDSCH对应的HARQ进程是反馈禁用的方法如第一方面所述,此处不再赘述。
因此,可以在同时支持HARQ反馈使能/禁用这一HARQ机制以及通过一个DCI调度多个PDSCHs这一调度方式的情况下不发送HARQ反馈信息;因此,不仅可以减少终端设备的PDCCH的监听次数以降低终端设备监听PDCCH的复杂度和功耗,同时也可以减小用于发送下行控制信令(DCI)的资源开销以提升数据吞吐量;另一方面,可以减少上行控制信令开销,同时,网络设备无需等待终端设备上报HARQ反馈信息即可发送新数据,进而可以降低数据传输时延。
在一些实施例中,该时域位置的确定位置可以参考第一方面或第二方面的实施例,需要说明的是,该时域位置仅对应该PDSCH,也即该时域位置的预定时间之前没有其他对应该时域位置的下行传输,即没有下行传输在该时域位置反馈HARQ-ACK信息(码本),例如,时域位置的预定时间之前没有其他对应该时域位置的PDSCH,换句话说,该时域位置上没有其他PDSCH需要发送与其他PDSCH对应的HARQ反馈信息(码本)。
在一些实施例中,该终端设备根据DCI中的C-DAI和/或T-DAI确定该时域位置仅对应该PDSCH,和/或,所述终端设备根据SPS配置和/或激活状态确定该时域位置仅对应该PDSCH。
例如,该终端设备根据DCI中的C-DAI和/或T-DAI确定该时域位置仅对应该PDSCH。也就是说,根据DCI中的C-DAI和/或T-DAI可以确定接收到的各个DCI,或各个DCI调度的PDSCH,由此确定该时域位置的预定时间之前是否有其他对应该 时域位置的下行传输(e.g PDSCH),进而确定该时域位置是否仅对应该PDSCH(该时域位置的预定时间之前没有其他对应该时域位置的下行传输,确定该时域位置仅对应该PDSCH)。同样的,所述终端设备根据DCI中的C-DAI和/或T-DAI确定不在所述PDSCH对应的用于发送HARQ反馈码本的时域位置发送HARQ反馈码本,也就是说,根据DCI中的C-DAI和/或T-DAI可以确定接收到的各个DCI,或各个DCI调度的PDSCH,由此确定该时域位置的预定时间之前是否有其他对应该时域位置的下行传输(e.g PDSCH),进而确定该时域位置是否仅对应该PDSCH,进而确定是否在所述PDSCH对应的用于发送HARQ反馈码本的时域位置发送HARQ反馈码本(该时域位置仅对应该PDSCH,确定不在所述PDSCH对应的用于发送HARQ反馈码本的时域位置发送HARQ反馈码本,上述DCI可以是调度该接收PDSCH的DCI,但本申请实施例并不以此作为限制,上述DCI还可以是调度该接收PDSCH的DCI之前预定时间或之后预定时间内接收到的DCI。
在一些实施例中,在以下1)-3)的情况中,所述终端设备根据DCI中的C-DAI和/或T-DAI确定需要在所述PDSCH对应的用于发送HARQ反馈码本的时域位置发送HARQ反馈码本(半静态码本或动态码本):
1)只接收到调度的(一个或多个)PDSCH对应HARQ process是反馈禁用的DCI(一个或多个),但有漏检(没有接收到的)的(用于调度或不用于调度PDSCH)DCI(例如根据接收到的DCI中的C-DAI/T-DAI确定)。
2)只接收到一个DCI,该DCI调度的PDSCH对应HARQ process是反馈禁用,该DCI的C-DAI不为第一特定值,e.g.1,和/或,T-DAI(如该DCI包括)不为第二特定值,e.g.1。(假设C-DAI基于DCI计数)。
3)只接收到一个DCI,该DCI调度的PDSCH对应HARQ process是反馈禁用,且该DCI的C-DAI不为第一特定值,e.g.1,或者为该DCI调度的PDSCH数,和/或,T-DAI(如该DCI包括)不为第二特定值,e.g.1,或者Wie该DCI调度的PDSCH数。(假设DAI基于PDSCH计数)。
在上述情况1)-3)中,该反馈码本的信息比特都是NACK,上述DCI是仅可以调度一个PDSCH的DCI或者可以调度多个PDSCH的DCI。
图15A至图15C以接收到一个DCI,且该DCI调度一个PDSCH为例说明上述情况1)-3)的C-DAI和T-DAI;图31A至图31D以接收到一个DCI,且该DCI调 度多个PDSCH为例说明上述情况1)-3)的C-DAI和T-DAI,图31A至图31D中,DAI以DCI为粒度计数;图32A至图32D以接收到一个DCI,且该DCI调度多个PDSCH为例说明上述情况1)-3)的C-DAI和T-DAI,图32A至图32D中,DAI以PDCCH为粒度计数;也就是在图15A至图15C,图31A至图31D,图32A至图32D的场景下,终端设备根据DCI中的C-DAI和/或T-DAI确定需要在所述PDSCH对应的用于发送HARQ反馈码本的时域位置发送HARQ反馈码本(半静态码本或动态码本),但该反馈码本的信息比特都是NACK。
在一些实施例中,除了PDCCH对应的HARQ进程是反馈禁用的情况下,在以下4)-6)的情况中,所述终端设备根据DCI中的C-DAI和/或T-DAI确定不需要在所述PDSCH对应的用于发送HARQ反馈码本的时域位置发送HARQ反馈码本(半静态码本或动态码本):
4)只接收到调度的PDSCH对应HARQ process是反馈禁用的DCI(一个或多个),且没有漏检(没有接收到的)的(用于调度或不用于调度PDSCH)DCI(例如根据接收到的DCI中的C-DAI/T-DAI确定)。
5)只接收到一个DCI,该DCI调度的PDSCH对应HARQ process是反馈禁用,该DCI的C-DAI为第一特定值,e.g.0/1,和/或,T-DAI(如该DCI包括)为第二特定值,e.g.0/1。(假设C-DAI基于DCI计数)。
该DCI是仅可以调度一个PDSCH的DCI或可以调度多个PDSCH的DCI)
6)只接收到一个DCI,该DCI调度的PDSCH对应HARQ process是反馈禁用,且该DCI的C-DAI为第一特定值,e.g.0/1,或者该DCI调度的PDSCH数,和/或,T-DAI(如该DCI包括)为第二特定值,e.g.0/1,或者该DCI调度的PDSCH数。(假设DAI基于PDSCH计数)。
图33A至图33B以接收到一个DCI,且该DCI调度一个PDSCH为例说明上述情况4)-6)的C-DAI和T-DAI;图34A至图34B以接收到一个DCI,且该DCI调度多个PDSCH为例说明上述情况4)-6)的C-DAI和T-DAI,图34A至图34D中,DAI以DCI为粒度计数;图35A至图35D以接收到一个DCI,且该DCI调度多个PDSCH为例说明上述情况4)-6)的C-DAI和T-DAI,图35A至图35D中,DAI以PDCCH为粒度计数;也就是在图33A至图33B,图34A至图34B,图35A至图35D的场景下,终端设备根据DCI中的C-DAI和/或T-DAI确定不需要在所述PDSCH对 应的用于发送HARQ反馈码本的时域位置发送HARQ反馈码本(半静态码本或动态码本)。
例如,终端设备根据SPS配置和/或激活状态确定该时域位置仅对应该PDSCH。也就是说,根据SPS配置和/或激活状态可以确定SPS PDSCH,由此确定该时域位置的预定时间之前是否有其他对应该时域位置的下行传输(e.g SPS PDSCH),进而确定该时域位置是否仅对应该PDSCH(该时域位置的预定时间之前没有其他对应该时域位置的下行传输,确定该时域位置仅对应该PDSCH)。同样的,所述终端设备根据SPS配置和/或激活状态确定不在所述PDSCH对应的用于发送HARQ反馈码本的时域位置发送HARQ反馈码本。也就是说,根据根据SPS配置和/或激活状态可以确定SPS PDSCH,由此确定该时域位置的预定时间之前是否有其他对应该时域位置的下行传输(e.g SPS PDSCH),进而确定该时域位置是否仅对应该PDSCH,进而确定是否在所述PDSCH对应的用于发送HARQ反馈码本的时域位置发送HARQ反馈码本(该时域位置仅对应该PDSCH,确定不在所述PDSCH对应的用于发送HARQ反馈码本的时域位置发送HARQ反馈码本。
在一些实施例中,该PDSCH对应的用于发送HARQ反馈信息的时域位置(例如时隙n+k)可以根据调度该PDSCH的DCI调度的最后一个对应HARQ反馈使能的HARQ进程的PDSCH所在时域位置确定,具体可以参考第一方面或第二方面的实施例,此处不再赘述。
在一些实施例中,在1402中,该HARQ反馈码本也可以只针对该接收PDSCH的HARQ反馈信息。
例如,在终端设备没有配置或激活SPS时,在终端设备仅接收到第一方面所述的至少一个第二DCI时,该1401中接收的PDSCH是DCI调度的PDSCH中的PDSCH,该第二DCI调度的所有第二PDSCH对应的HARQ进程都是反馈禁用的,这之后,在终端设备接收到该第二PDSCH中的一个或多个或全部PDSCH(以下统称为接收的PDSCH)时,可以跳过反馈码本(例如半静态码本)的生成(不生成该反馈码本),也就是说,不在接收的PDSCH对应的用于发送HARQ反馈信息的时域位置发送HARQ反馈信息(或者说码本)。至少两个第二DCI调度的PDSCH和SPS PDSCH对应相同的用于发送HARQ反馈信息的时域位置。
例如,在终端设备被配置或激活SPS PDSCH,且该1401中接收的PDSCH是SPS  PDSCH时,该终端设备可以跳过反馈码本(例如半静态码本)的生成(不生成该反馈码本),也就是说,不在接收的SPS PDSCH对应的用于发送HARQ反馈信息的时域位置发送针对该SPS PDSCH的HARQ反馈信息(或者说码本)。
例如,在终端设备被配置或激活SPS,且终端设备仅接收到第一方面所述的至少一个第二DCI时,该1401中接收的PDSCH包括DCI调度的PDSCH和SPS PDSCH,该终端设备可以跳过反馈码本(例如半静态码本)的生成(不生成该反馈码本),也就是说,不在接收的DCI调度的PDSCH和SPS PDSCH对应的用于发送HARQ反馈信息的时域位置发送针对该SPS PDSCH的HARQ反馈信息(或者说码本)。其中,该DCI调度的PDSCH和SPS PDSCH对应相同的用于发送HARQ反馈信息的时域位置。
例如,与第二方面的实施例不同之处在于,在终端设备仅接收到第二方面所述的至少一个第四DCI时,该1401中接收的PDSCH是第四DCI调度的PDSCH中的PDSCH,该第四DCI调度的所有第二PDSCH对应的HARQ进程都是反馈禁用的,这之后,在终端设备接收到该第二PDSCH中的一个或多个或全部PDSCH(以下统称为接收的PDSCH)时,可以忽略该第四DCI中的C-DAI和/或T-DAI。
由上述实施例可知,针对对应HARQ进程反馈禁用的PDSCH,可以不在该PDSCH对应的用于发送HARQ反馈码本的时域位置发送HARQ反馈码本,由此,可以在支持HARQ反馈使能/禁用这一HARQ机制的情况下不发送HARQ反馈信息;因此,可以减少上行控制信令开销,同时,网络设备无需等待终端设备上报HARQ反馈信息即可发送新数据,进而可以降低数据传输时延。
