Abstract
本申请实施例提供一种数据发送方法、数据接收方法和装置,数据接收方法包括:终端设备接收第一下行控制信息,第一下行控制信息用于调度PDSCH(201);终端设备接收第一下行控制信息调度的PDSCH中的一个或多于一个PDSCH(202)。
Description
本申请实施例涉及通信技术领域。
物理下行共享信道(Physical Downlink Shared Channel,PDSCH)是无线通信系统中物理下行信道的一种,用于承载下行数据。物理上行共享信道(Physical Uplink Shared Channel,PUSCH)是无线通信系统中物理上行信道的一种,用于承载上行数据。
PDSCH和PUSCH可以是通过下行控制信息(downlink control information,DCI)调度的。用于调度PDSCH或PUSCH的DCI中至少包括用于指示该DSCH的资源的信息域(或者说字段)。在目前的新无线(new radio,NR)系统中,定义了多种用于调度PDSCH或PUSCH的DCI格式(format),例如DCI format 1_0(用于调度PDSCH)、DCI format 0_0(用于调度PUSCH)、DCI format 1_1(用于调度PDSCH)、DCI format 0_1(用于调度PUSCH)、DCI format 1_2(用于调度PDSCH)、DCI format 0_2(用于调度PUSCH)等,不限于此。不同DCI format的DCI包括的具体信息和/或大小是不一样的,以满足不同的调度需求。
PDSCH和PUSCH还可以是半静态配置(或者说半静态调度)或半持续调度的。在NR中,半静态配置或半持续调度的PDSCH例如称为SPS PDSCH。半静态配置或半持续调度的PUSCH例如称为CG PUSCH。在一些情况下,网络设备在通过RRC信令提供SPS或CG配置后,还需要通过DCI激活SPS或CG配置,终端设备才相应地接收SPS PDSCH或发送CG PUSCH。
应该注意,上面对技术背景的介绍只是为了方便对本申请的技术方案进行清楚、完整的说明,并方便本领域技术人员的理解而阐述的。不能仅仅因为这些方案在本申请的背景技术部分进行了阐述而认为上述技术方案为本领域技术人员所公知。
发明内容
发明人发现,通过一个DCI调度多于一个PDSCH/PUSCH的技术还在讨论中, 此外,现有技术假设一个DCI仅能调度一个PDSCH/PUSCH,进而基于这样的DCI支持半静态调度或半持续调度PDSCH或PUSCH,以及支持针对对应半静态调度或半持续调度的数据的动态重传,没有考虑一个DCI(或者说DCI format)可能调度多于一个PDSCH/PUSCH的情况下如何支持半静态调度或半持续调度PDSCH或PUSCH,以及针对对应半静态调度或半持续调度的数据的动态重传。
针对上述问题,本申请实施例提供一种数据发送方法、数据接收方法和装置,以支持通过一个DCI调度多于一个PDSCH/PUSCH,进一步的,在一个DCI(或者说DCI format)可以调度多于一个PDSCH/PUSCH的情况下的半静态调度或半持续调度PDSCH或PUSCH,以及支持针对对应半静态调度或半持续调度的数据的动态重传。
根据本申请实施例的一方面,通过一种数据接收装置,配置于终端设备,所述装置包括:
第一接收单元,其接收第一下行控制信息,所述第一下行控制信息用于调度PDSCH;
第二接收单元,其接收所述第一下行控制信息调度的PDSCH中的一个或多于一个PDSCH。
根据本申请实施例的另一方面,提供一种数据接收装置,配置于终端设备,所述装置还包括:
第一接收单元,其接收包括用于配置重复次数的第一配置参数的PDSCH配置;
第二接收单元,其接收用于激活SPS配置的第二下行控制信息,
所述第一配置参数应用于所述第二下行控制信息,所述第二下行控制信息对应的TDRA表中的一行或多于一行包括多于一个SLIV。
根据本申请实施例的又一方面,提供一种数据发送装置,配置于终端设备,所述装置包括:
第一接收单元,其接收第三下行控制信息,所述第三下行控制信息用于调度PUSCH;
发送单元,其发送所述第三下行控制信息调度的PUSCH中的一个或多于一个PUSCH。
本申请实施例的有益效果之一在于:根据本申请实施例,能够支持通过一个DCI调度多于一个PDSCH/PUSCH,进一步的,能够支持在一个DCI(或者说DCI format) 可以调度多于一个PDSCH/PUSCH的情况下的半静态调度或半持续调度PDSCH或PUSCH,以及支持针对对应半静态调度或半持续调度的数据的动态重传。进一步地,在一个DCI format(例如DCI format 1_1或DCI format 0_1)被配置为可以调度多于一个PDSCH或PUSCH的情况下,可以采用该DCI format激活/去激活SPS或CG配置,或者采用该DCI format调度针对对应半静态调度或半持续调度的数据的动态重传。也就是说,该DCI fomart可以既用于支持半静态调度或半持续调度,又用于支持动态调度PDSCH或PUSCH。这样,在被配置了SPS或CG以及上述DCI format被配置为可以调度多于一个PDSCH或PUSCH的情况下,针对下行或上行,UE仅需盲检该DCI format,而无需额外盲检除该DCI format之外用于支持半静态调度或半持续调度PDSCH或PUSCH和/或针对对应半静态调度或半持续调度的数据的动态重传的另一DCI format。由此,可以降低UE检测接收PDCCH的复杂度,减小功耗。另一方面,对于网络设备来说,也可以提高配置及资源调度的灵活性。

图1是本申请实施例的通信系统的示意图,示意性说明了以终端设备和网络设备为例的情况,如图1所示,通信系统100可以包括网络设备101和终端设备102、103。为简单起见,图1仅以两个终端设备和一个网络设备为例进行说明,但本申请实施例不限于此。

在现有技术中,SPS和CG可以支持聚合/重复(aggregation/repetition)。对于SPS PDSCH,如果SPS配置(sps-Config)中包括pdsch-AggregationFactor,则按该pdsch-AggregationFactor配置的次数重复;如果SPS配置(sps-Config)中不包括pdsch-AggregationFactor,但PDSCH配置(pdsch-Config)中包括pdsch-AggregationFactor,则按该PDSCH配置中pdsch-AggregationFactor配置的次数重复。对于CG PUSCH,如果用于激活该CG PUSCH的DCI指示的TDRA(时域资源分配)配置中包括numberOfRepetitions,则按该numberOfRepetitions配置的次数重复。如果用于激活该CG的DCI指示的TDRA配置不包括numberOfRepetitions(包括无需DCI激活的情况),但CG配置(ConfiguredGrantConfig)中包括repK,则按repK配置的次数重复。
另一方面,SPS和CG的重传也可以支持聚合/重复。该重传是通过DCI调度的。该DCI的CRC由CS-RNTI加扰,且NDI=1。对于SPS的重传,如果PDSCH配置(pdsch-Config)中包括pdsch-AggregationFactor,则按该PDSCH配置中pdsch-AggregationFactor配置的次数重复。对于CG的重传,如果DCI指示的TDRA配置中包括numberOfRepetitions,则按该numberOfRepetitions配置的次数重复;如果DCI指示的TDRA配置中不包括numberOfRepetitions,但PUSCH配置(pusch-Config)中包括pusch-AggregationFactor,则按pusch-AggregationFactor配置的次数重复。
然而,上述现有技术假设一个DCI仅能调度一个PDSCH/PUSCH,没有考虑一个DCI可以调度多于一个PDSCH/PUSCH的情况。
另一方面,在Rel-17(版本17)中,根据目前的讨论,为了支持通过一个DCI调度多个PDSCH,针对DCI format 1_1,可以配置一个TDRA表,该TDRA表的一行或多行分别包括多个SLIVs,SLIV与PDSCH一一对应。这样,通过采用DCI format 1_1指示包括多个SLIVs的行,可以调度多个PDSCH。在这种情况下,若PDSCH配置(pdsch-Config)中包括pdsch-AggregationFactor,该pdsch-AggregationFactor不用于DCI format 1_1。
类似地,为了支持通过一个DCI调度多个PUSCH,针对DCI format 0_1,可以 配置一个TDRA表,该TDRA表的一行或多行分别包括多个SLIVs,SLIV与PUSCH一一对应。这样,通过采用DCI format 0_1指示包括多个SLIVs的行,可以调度多个PUSCH。在这种情况下,若PUSCH配置(pusch-Config)中包括pdsch-AggregationFactor,该pdsch-AggregationFactor不用于DCI format 1_1。
然而,在上述讨论中,没有DCI format 1_1和DCI format 0_1可能分别用于SPS的激活和重传以及CG的激活和重传的情况。根据上述现有技术和讨论,无法确定针对由上述DCI format 1_1和DCI format 0_1激活的SPS PDSCH(或者说激活的SPS对应的PDSCH)是否支持聚合/重复(aggregation/repetition)。
发明人发现,DCI format 1_1和DCI format 0_1配置上述TDRA表的情况下,一方面,目前还没有DCI format 1_1和DCI format 0_1分别用于SPS的重传和CG的重传的方法;另一方面,假设上述DCI format 1_1和DCI format 0_1分别用于SPS的激活和重传以及CG的激活和重传,根据上述现有技术和讨论,无法确定针对由上述DCI format 1_1和DCI format 0_1激活的SPS PDSCH(或者说激活的SPS对应的PDSCH)或者由上述DCI format 1_1和DCI format 0_1调度的对应SPS或CG的数据重传(分别由动态调度的PDSCH和PUSCH承载)是否/如何支持聚合/重复(aggregation/repetition),也就是说,在假设下,目前还没有是否/如何支持聚合/重复(aggregation/repetition)的确定性方案,终端设备将无法确定是否采用了聚合/重复(aggregation/repetition)的方式,从而可能无法正确接收或发送数据。
针对上述问题,提出了本申请。
在本申请实施例中,DCI在调度PDSCH/PUSCH时或者在激活SPS/CG时需要指示PDSCH/PUSCH的时域资源。一般地,DCI中包括用于指示PDSCH/PUSCH的时域资源的信息域,该信息域基于应用的(或者对应的)时域资源分配表(TDRA)表(或者称为PDSCH/PUSCH TDRA表,或者简称为TDRA表)指示PDSCH/PUSCH的时域资源。该信息域例如是时域资源分配(Time domain resource assignment)域。具体地,该信息域可以指示一个时域资源分配配置(或者简称为TDRA配置)在TDRA表中的索引。例如,上述TDRA表是该DCI应用的TDRA表,该信息域通过指示该DCI应用的TDRA表中的TDRA配置的索引(行索引,例如行索引的值大于或等于1)来指示PDSCH的时域资源,换句话说,该DCI通过指示其应用的TDRA表中的TDRA配置来调度PDSCH。例如,该DCI的信息域的值m(假设m为大于或等于0 的整数)对应指示该DCI应用的TDRA表中索引为m+1(也就是第m+1行)的TDRA配置。时域资源分配表是预定义的或RRC信令配置的。在该TDRA表是RRC信令配置的情况下,例如,该RRC信令配置的第m+1个TDRA配置对应的索引值为m+1,也就是说,信息域的值为m时,其对应的是该RRC信令配置的第m+1个TDRA配置。
在本申请实施例中,时域资源分配表包括至少一行,以下,为方便描述,将一行称为一个TDRA配置,即TDRA表包括至少一个TDRA配置。一个TDRA配置包括至少一个时域资源配置(或者称为PDSCH/PUSCH时域资源配置),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/PUSCH TDRA配置还可以包括至少一个时隙偏移(例如称为K0)配置,K0表示PDSCH/PUSCH与PDCCH/PUCCH的时隙偏移,K0配置包括在PDSCH/PUSCH时域资源配置中或者不包括在PDSCH/PUSCH时域资源配置中;该一个TDRA配置还可以包括其他信息,且该其他信息包括在PDSCH/PUSCH时域资源配置中或者不包括在PDSCH/PUSCH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,起点和长度指示),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。
在一些实施例中,为了支持通过一个DCI调度多个PDSCH/PUSCH,可以支持通过新的RRC信令(例如,针对PDSCH的pdsch-TimeDomainAllocationListForMultiPDSCH或者pdsch-TimeDomainAllocationListForMultiPDSCH-r17;针对PUSCH的pusch-TimeDomainAllocationListForMultiPUSCH或者pusch-TimeDomainAllocationListForMultiPUSCH-r17)配置用于支持通过一个DCI调度多个(即多于一个)PDSCH/PUSCH的时域资源分配表,该时域资源分配表包括至少一个用于调度多个(即多于一个)PDSCH/PUSCH的时域资源分配配置,该时域资源分配配置例如包括多个SLIV,每个SLIV分别对应一个PDSCH/PUSCH。
在一些实施例中,该时域资源分配配置包括一个时域偏移K0配置,K0表示第一个PDSCH/PUSCH与承载调度该PDSCH/PUSCH的DCI的PDCCH/PUCCH之间 的时隙偏移。
在一些实施例中,该时域资源分配配置包括多个(即多于一个)K0配置。例如,该配置包括多个K0,每个K0分别对应一个PDSCH/PUSCH,分别表示相应PDSCH/PUSCH与用于调度该PDSCH/PUSCH的PDCCH/PUCCH之间的时隙偏移,可选的,该K0可以包含在PDSCH/PUSCH时域资源配置中,与每个SLIV一一对应,由此,可以依次确定多个PDSCH/PUSCH的时隙位置。
在一些实施例中,若一个时域资源分配配置用于调度连续多个时隙中的多个PDSCH/PUSCH,该配置中包括一个时域偏移K0配置,K0例如表示第一个PDSCH/PUSCH与承载调度该PDSCH/PUSCH的DCI的PDCCH/PUCCH之间的时隙偏移。若一个时域资源分配配置用于调度非连续的多个时隙中的多个PDSCH/PUSCH,该时域资源分配配置包括多个(即多于一个)时域偏移K0配置。例如,该配置包括多个K0,每个K0分别对应一个PDSCH/PUSCH,分别表示相应PDSCH/PUSCH与用于调度该PDSCH/PUSCH的PDCCH/PUCCH之间的时隙偏移,可选的,该K0可以包含在PDSCH/PUSCH时域资源配置中,与每个SLIV一一对应,由此,可以依次确定多个PDSCH/PUSCH的时隙位置。
在一些实施例中,针对下行,在配置了上述TDRA表的情况下,该TDRA表应用于/对应DCI format 1_1;针对上行,在配置了上述TDRA表的情况下,该TDRA表应用于/对应DCI format 0_1。上述TDRA表针对下行和上行是分别配置的。
在一些实施例中,所述终端设备确定DCI(或者说DCI with DL grant/assignment)应用的时域资源分配表。终端设备还可以根据第一列表确定该DCI应用的时域资源分配表,该第一列表的一列对应前述的用于配置用于支持通过一个DCI调度多个PDSCH/PUSCH的TDRA表的指示信息(例如,针对PDSCH的pdsch-TimeDomainAllocationListForMultiPDSCH或者pdsch-TimeDomainAllocationListForMultiPDSCH-r17;针对PUSCH的pusch-TimeDomainAllocationListForMultiPUSCH或者pusch-TimeDomainAllocationListForMultiPUSCH-r17)。该指示信息例如包括在PDSCH/PUSCH-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/PUSCH时域资源分配(TDRA)表中确定用于调度PDSCH/PUSCH的DCI应用的PDSCH/PUSCH时域资源分配表。以DCI为DCI format 1_0和1_1为 例,下表1为第一列表的一个示例表。
表1:针对DCI format 1_0和DCI format 1_1的可应用的PDSCH时域资源分配
在本申请实施例中,DCI指示了多个(即多于一个)PDSCH/PUSCH是指DCI(或者说DCI中的第二信息域)指示了用于调度多于一个PDSCH/PUSCH的时域资源分配配置。关于时域资源分配配置已经在前面做了说明,此处不再赘述。
在本申请实施例中,DCI调度了多个(即多于一个)PDSCH/PUSCH是指DCI指示了多个PDSCH/PUSCH,或者是指DCI指示的多个PDSCH/PUSCH包括多于一个有效(valid)的PDSCH/PUSCH,或者是指该DCI指示的多个PDSCH/PUSCH中有对应的HARQ process(或者说HARQ process ID)的PDSCH/PUSCH。其中,有效的PDSCH和/或有对应的HARQ process的PDSCH例如是指不和半静态配置的上行符号和/或动态配置的上行符号和/或半静态配置的上行传输所在的符号和/或预留符号和/或间隔符号重叠的PDSCH。有效的PUSCH和/或有对应的HARQ process的PUSCH例如是指不和半静态配置的下行符号和/或SSB对应的符号和/或CORSET#0对应的符号和/或动态配置的下行符号和/或半静态配置的下行传输所在的符号和/或预留符号和/或间隔符号重叠的PDSCH。其中,有效的PDSCH/PUSCH和有对应的HARQ process的PDSCH/PUSCH相同或不同。针对不同的情况,例如,有效的PDSCH例如是指不和半静态配置的上行符号重叠的PDSCH,有效的PUSCH例如是指不和半静态配置的下行符号和/或SSB对应的符号和/或CORSET#0对应的符号重叠的PUSCH,有对应的HARQ process的PDSCH例如是指不和半静态配置的上行符号和/或动态配置的上行符号重叠的PDSCH,有对应的HARQ process的PUSCH例如是指不和半静态配置的下行符号和/或SSB对应的符号和/或CORSET#0对应的符号和/或动态配置的下行符号重叠的PUSCH。换句话说,如果DCI指示的PDSCH与半静态配置的上行符号和/或动态配置的上行符号和/或半静态配置的上行传输所在的符号和/或预留符号和/或间隔符号重叠,则该PDSCH是无效(invalid)PDSCH,和/或该PDSCH没有对应的HARQ process(或者说HARQ process ID)。再例如,如果DCI指示的PUSCH与半静态配置的下行符号和/或SSB对应的符号和/或CORSET#0对应的符号和/或动态配置的下行符号和/或半静态配置的下行传输所在的符号和/或预留符号和/或间隔符号重叠,则该PUSCH是无效(invalid)PUSCH,和/或该PUSCH没有对应的HARQ process(或者说HARQ process ID)。
例如,假设有效的PDSCH和/或有对应的HARQ process的PDSCH是指不和半 静态配置的上行符号重叠的PDSCH,若一个PDSCH和半静态配置的上行符号重叠/冲突,则该PDSCH没有对应的HARQ process(或者说HARQ process ID)。一般地,基站不会发送该PDSCH,UE也不接收该PDSCH。反之,若PDSCH不和半静态配置的上行符号重叠/冲突,则该PDSCH有对应的HARQ process(或者说HARQ process ID)。

下面结合附图和具体实施方式对本申请实施例进行说明。
在本申请实施例中,“当……时”、“在……情况下”、“对于……的情况”以及“如果……”表示基于某个或某些条件或状态等,另外,这些表述方式可以互相替换。此外,“指示”可以是显式地包含某些信息以进行通知,也可以是隐式地通过某些特征进行通知等。此外,“DCI”、“DCI格式”、“DCI format”等表述指代相同的含义,可以互相替换。此外,“可以调度”、“能够调度”、“用于调度”等表述指代相同的含义,可以互相替换。
第一方面的实施例
本申请实施例提供一种数据接收方法,从终端设备的一侧进行说明。
图2是本申请实施例的数据接收方法的一示意图,如图2所示,该方法包括:
201,终端设备接收第一下行控制信息(DCI),所述第一DCI用于调度物理下行共享信道(PDSCH);
202,所述终端设备接收所述第一DCI调度的PDSCH中的一个或多于一个PDSCH。
根据本申请实施例,终端设备接收第一DCI调度的一个或多于一个PDSCH,由此,能够支持通过一个DCI调度多于一个PDSCH,进一步的,能够支持在一个DCI(或者说DCI format)可以调度多于一个PDSCH的情况下的半静态调度或半持续调度PDSCH,以及支持针对对应半静态调度或半持续调度的数据的动态重传。
在一些实施例中,在终端设备接收第一DCI调度的PDSCH中的多于一个PDSCH的情况下,该多于一个PDSCH中的不同的PDSCH承载的数据(也即传输块TB)不同。由此,能够支持通过一个DCI指示不同传输块的传输。
在一些实施例中,第一DCI是DCI format 1_1,也即,网络设备通过DCI format 1_1调度多个PDSCH。
在一些实施例中,第一DCI包括一个NDI(New Data Indication,新数据指示)域或者两个NDI域,在该第一DCI包括两个NDI域的情况下,各NDI域分别对应一个TB。例如,第一DCI包括第一NDI域和/或第二NDI域,在第一DCI包括第一NDI域和第二NDI域的情况下,该第一NDI域和该第二NDI域分别对应第一个TB和第二个TB。由此,可以通过NDI域对TB进行指示。
在上述实施例中,第一NDI域和/或第二NDI域的值为0或者1。
在一些实施例中,在第一DCI的CRC由CS-RNTI加扰的情况下,第一NDI域和/或第二NDI域包括的比特数可以根据以下至少一项确定,即:
第一DCI可调度的PDSCH的最大数(也即,第一DCI对应的TDRA表中一行包括的SLIV的最大数);
第一DCI调度的PDSCH数(也即,第一DCI指示的行包括的SLIV数);
第一DCI调度调度有效的PDSCH数(也即,第一DCI指示的行包括的有效的SLIV数)。
由此,第一NDI域和/或第二NDI域可以包括一个比特,也可以包括多于一个比特,具体取决于上述至少一项决定因素。
在另一些实施例中,在第一DCI的CRC由CS-RNTI加扰的情况下,上述第一NDI域和/或第二NDI域只有1个比特。例如,当配置了2个TB时,第一DCI中包括1个NDI域,该NDI域为1个比特;或者,第一DCI中包括2个NDI域,且各TB对应的NDI域的比特数为1。在该实施例中,NDI域的比特数不取决于前述实施例中的决定因素。
在一些实施例中,第一DCI对应的TDRA表中的一行或多于一行包括多于一个SLIV,该多于一个SLIV对应多于一个PDSCH,由此实现了通过该第一DCI调度多于一个PDSCH。
在上述实施例中,在一些实施方式中,不采用上述第一DCI调度SPS的重传,也即,终端设备不期望该第一DCI的CRC由CS-RNTI加扰;在一些实施方式中,第一DCI的第一NDI域和/或第二NDI域的值为1;在一些实施方式中,第一DCI调度多于一个PDSCH;在一些实施方式中,第一DCI调度多于一个有效的PDSCH;在一些实施方式中,第一DCI的NDI域(第一NDI域和/或第二NDI域)中包括多于一个值为1的比特;在一些实施方式中,第一DCI调度的多于一个PDSCH对应的HARQ进程ID是针对SPS配置的一个或多于一个HARQ进程ID之一;在一些实施方式中,第一DCI调度的一个或多于一个PDSCH对应的HARQ进程ID不是针对SPS配置的一个或多于一个HARQ进程ID之一。上述各实施方式可以分别实施,也可以任意组合。
在上述实施例中,第一NDI域和/或第二NDI域的值为1,包括但不限于:
第一NDI域包括1个比特,该1个比特的值为1;或者,
第一NDI域包括多于1个比特,该第一NDI域的一个或多于一个特定比特的值为1,或者,该第一NDI域的至少1个比特的值为1,或者,该第一NDI域的所有比特的值为1;或者,
第二NDI域包括1个比特,该1个比特的值为1;或者,
第二NDI域包括多于1个比特,该第二NDI域的一个或多于一个特定比特的值为1,或者,该第二NDI域的至少1个比特的值为1,或者,该第二NDI域的所有比特的值为1。
在本申请实施例中,在一些实施例中,第一DCI的CRC由CS-RNTI加扰,该第一DCI仅调度一个PDSCH(也即,该第一DCI指示对应的TDRA表中包括一个SLIV的行),终端设备仅接收该一个PDSCH。
例如,在针对DCI format 1_1(第一DCI)配置上述TDRA表的情况下,若UE接收到CRC由CS-RNTI加扰且NDI=1(针对两个TB的情况,各TB分别对应一个NDI域,均为1或者其中一个(例如第一个TB)对应的NDI域为1)的DCI format 1_1,该DCI只能指示包括一个SLIV的行,不能指示包括多个SLIV的行。即,该DCI只能指示或调度一个PDSCH。
在这个例子中,该DCI中指示的HARQ process ID可以对应该PDSCH。该HARQ process ID可以在针对SPS配置HARQ process组中,但是本申请不限于此,该DCI中指示的HARQ process ID也可以有其他实施方式,具体如前所述,此处省略说明。
在本申请实施例中,在一些实施例中,第一DCI的CRC由CS-RNTI加扰,该第一DCI调度多于一个PDSCH(也即,该第一DCI指示对应的TDRA表中包括多于一个SLIV的行)。
在上述实施例中,终端设备可以根据以下至少一项确定是否接收该第一DCI调度的多于一个PDSCH中的PDSCH:
PDSCH对应的HARQ process ID;
PDSCH对应的NDI域比特的值;
PDSCH是否和半静态配置的上行符号冲突。
例如,根据PDSCH是否和半静态配置的上行符号冲突,终端设备仅接收上述多于一个PDSCH中的其中一个PDSCH。
在这个例子中,该一个PDSCH可以是上述多于一个PDSCH中的第一个PDSCH 或最后一个PDSCH,也可以是上述多于一个PDSCH中唯一一个有效的PDSCH,还可以是上述多于一个PDSCH中唯一一个相应的NDI域的值为1的PDSCH,还可以是上述多于一个PDSCH中唯一一个对应的HARQ进程ID是针对SPS配置的一个或多于HARQ进程ID之一的PDSCH。本申请不限于此,上述一个PDSCH还可以是其他或者上述任意组合。
下面通过具体的示例对这个例子进行说明。
在针对DCI format 1_1(第一DCI)配置上述TDRA表的情况下,若UE接收到CRC由CS-RNTI加扰且NDI=1或‘1’s(针对两个TB的情况,各TB分别对应一个NDI域,均为1或‘1’s,或者其中一个(例如第一个TB)对应的NDI域为1或‘1’s)的DCI format 1_1且指示包括多个SLIV的行,即该DCI可以指示/调度多于一个PDSCH。UE仅接收其中一个PDSCH,例如按时间顺序的第一个PDSCH或最后一个PDSCH,和/或,唯一一个有效的PDSCH(例如不和半静态配置的上行符号冲突的PDSCH),和/或,唯一一个相应NDI比特为1的PDSCH,和/或对应的HARQ进程ID是针对SPS配置的一个或多于HARQ进程ID之一的PDSCH。
在这个例子中,该第一DCI指示的HARQ进程ID可以对应上述一个PDSCH(无论该PDSCH是否是第一个PDSCH);或者,该第一DCI指示的HARQ进程ID对应上述多于一个PDSCH中第一个有效的PDSCH,终端设备根据该HARQ进程ID确定上述一个PDSCH对应的HARQ进程ID(无论该PDSCH是否是第一个PDSCH)。
在这个例子中,上述一个PDSCH对应的HARQ进程ID可以是针对SPS配置的一个或多于一个HARQ进程ID之一,也即在针对SPS配置的HARQ进程ID组中。
在这个例子中,上述一个PDSCH可以是有效的PDSCH。
在这个例子中,上述第一个PDSCH可以是上述第一DCI调度的第一个PDSCH或者是上述第一DCI调度的第一个有效的PDSCH;同理,上述述最后一个PDSCH可以是上述第一DCI调度的最后一个PDSCH或者是上述第一DCI调度的最后一个有效的PDSCH。其中,第一DCI调度的第一个PDSCH也即第一DCI指示的行中第一个SLIV对应的PDSCH(有效的PDSCH),同理,第一DCI调度的最后一个PDSCH也即第一DCI指示的行中最后一个SLIV对应的PDSCH(有效的PDSCH)。
在这个例子中,针对UE仅接收唯一一个有效的PDSCH,即该DCI指示/调度的PDSCH只能包括一个有效的PDSCH,也就是说,UE不期望该DCI中指示/调度多于 一个有效的PDSCH。UE也就仅接收该一个PDSCH。
在这个例子中,针对UE仅接收唯一一个相应NDI比特为1的PDSCH,该DCI的NDI域中只包括一个值为1的比特,也就是说,UE不期望该DCI的NDI域中包括多于一个值为1的比特。UE也就仅接收该一个PDSCH。
在这个例子中,UE不接收无效的(invalid)PDSCH,且无效的PDSCH没有对应的HARQ process ID。
在这个例子中,针对其他(有效的)PDSCH(如果有),UE不接收,或者说取消其他(有效的)PDSCH接收。其他(有效的)PDSCH对应或不对应HARQ process ID(或者说,UE确定或不确定其他(有效的)PDSCH的HARQ process ID))。
再例如,根据PDSCH对应的HARQ process ID,终端设备仅接收对应的HARQ进程ID是针对SPS配置的一个或多于一个HARQ进程ID之一的PDSCH。
下面通过具体的示例对这个例子进行说明。
在针对DCI format 1_1(第一DCI)配置上述TDRA表的情况下,若UE接收到CRC由CS-RNTI加扰且NDI=1或‘1’s(针对两个TB的情况,各TB分别对应一个NDI域,均为1或‘1’s,或者其中一个(例如第一个TB)对应的NDI域为1或‘1’s)的DCI format 1_1且指示包括多个SLIV的行,即该DCI可以指示/调度多于一个PDSCH。UE仅接收对应的HARQ process ID在针对SPS配置的HARQ process组中的PDSCH。
在这个例子中,该DCI中指示的HARQ process ID对应第一个有效的PDSCH,UE根据该指示确定有效的PDSCH的HARQ process ID。
在这个例子中,UE不接收对应的HARQ process ID不在针对SPS配置的HARQ process组中的PDSCH。
在这个例子中,UE不接收无效的PDSCH,且无效的PDSCH没有对应的HARQ process ID。
再例如,根据PDSCH对应的HARQ process ID,终端设备接收上述多于一个PDSCH中所有有效的PDSCH。
其中,在一个例子中,所有有效的PDSCH对应的HARQ进程ID必须都是针对SPS配置的一个或多于一个HARQ进程ID之一。
下面通过具体的示例对这个例子进行说明。
在针对DCI format 1_1(第一DCI)配置上述TDRA表的情况下,若UE接收到CRC由CS-RNTI加扰且NDI=1或‘1’s(针对两个TB的情况,各TB分别对应一个NDI域,均为1或‘1’s,或者其中一个(例如第一个TB)对应的NDI域为1或‘1’s)的DCI format 1_1且指示包括多个SLIV的行,即该DCI可以指示/调度多于一个PDSCH。该DCI指示/调度的多于一个PDSCH中包括的有效的PDSCH(s)对应的HARQ process ID(s)必须都在针对SPS配置的HARQ process组中。也就是说,UE不期望该DCI中指示/调度的任一个有效的PDSCH(s)对应的HARQ process ID(s)不在针对SPS配置的HARQ process组中。
其中,在另一个例子中,对应的HARQ进程ID不为针对SPS配置的一个或多于一个HARQ进程ID之一和/或对应的NDI域比特的值为0的PDSCH,为初传。
下面通过具体的示例对这个例子进行说明。
在针对DCI format 1_1(第一DCI)配置上述TDRA表的情况下,若UE接收到CRC由CS-RNTI加扰且NDI=1或‘1’s的DCI format 1_1且指示包括多个SLIV的行,即该DCI可以指示/调度多于一个PDSCH。UE接收所有有效的PDSCH(s),针对对应的HARQ process ID(s)不在针对SPS配置HARQ process组中的PDSCH,UE视为初传。
在这个例子中,所有有效的PDSCH中的仅一个或至少一个PDSCH对应的HARQ进程ID是针对SPS配置的一个或多于一个HARQ进程ID之一。也即,该DCI指示/调度的多于一个PDSCH中包括的有效的PDSCH(s)对应的HARQ process ID(s)的仅一个或至少一个在针对SPS配置的HARQ process组中。其中,该HARQ process ID(s)对应的有效的PDSCH(s)为重传。
在上述两个例子中,该DCI指示的HARQ process ID对应第一个有效的PDSCH,UE根据该指示确定有效的PDSCHs的HARQ process ID。
在上述两个例子中,UE接收所有有效的PDSCH(s)。
再例如,根据PDSCH对应的NDI域比特的值,终端设备仅接收对应的NDI域的比特的值为1的PDSCH;或者,终端设备接收所有有效的PDSCH,并且,针对对应的NDI域的比特的值为1的PDSCH视为重传,针对对应的NDI域的比特的值为0的PDSCH视为初传。
下面通过具体的示例对这个例子进行说明。
在针对DCI format 1_1(第一DCI)配置上述TDRA表的情况下,若UE接收到CRC由CS-RNTI加扰的DCI format 1_1且指示包括多个SLIV的行,其中,一个或多个SLIV对应的NDI比特=1(针对两个TB的情况,各TB分别对应一个NDI域,该一个或多个SLIV在两个NDI域中的相应比特均为1,或者其中一个(例如第一个TB)中的相应比特为1),即该DCI可以指示/调度多于一个PDSCH,且其中一个或多个PDSCH对应的NDI比特=1。
在这个例子中,UE仅接收NDI比特=1对应的PDSCH,或者,UE接收所有有效的PDSCH(s),针对对应的NDI比特=0的PDSCH,UE视为初传。
在这个例子中,所有有效的PDSCH中的仅一个或至少一个PDSCH对应的NDI域的比特的值为1。
在本申请实施例中,在一些实施例中,终端设备还可以接收包括用于配置重复次数的第一配置参数(例如pdsch-AggregationFactor)的PDSCH配置(pdsch-Config),在第一DCI的CRC由CS-RNTI加扰的情况下,该第一配置参数应用于该第一DCI。也即,在针对DCI format 1_1(第一DCI)配置上述TDRA表的情况下,当UE接收由CRC由CS-RNTI加扰且NDI=1或NDI=0的DCI format 1_1调度的PDSCH时,若PDSCH配置(pdsch-Config)中包括pdsch-AggregationFactor,按该pdsch-AggregationFactor配置的次数重复。
在上述实施例中,第一配置参数应用于第一DCI,是指:第一配置参数应用于第一DCI调度的PDSCH中的一个或多于一个PDSCH。
例如,第一DCI调度的各PDSCH按照第一配置参数配置的次数重复,和/或,第一DCI调度的各有效的PDSCH按照第一配置参数配置的次数重复;和/或,第一DCI调度的PDSCH中的终端设备需接收的各PDSCH按照第一配置参数配置的次数重复;和/或,第一DCI仅调度一个PDSCH且该一个PDSCH按照第一配置参数配置的次数重复;和/或,第一DCI调度的PDSCH中终端设备仅接收一个PDSCH且该一个PDSCH按照第一配置参数配置的次数重复。
在本申请实施例中,在一些实施例中,终端设备还可以接收包括用于配置重复次数的第一配置参数(例如pdsch-AggregationFactor)的PDSCH配置(pdsch-Config),在第一DCI的CRC由CS-RNTI加扰的情况下,该第一配置参数不应用于该第一DCI。
在上述实施例中,第一配置参数不应用于第一DCI,是指:第一配置参数不应用 于第一DCI调度的PDSCH中的任一个。
例如,在针对DCI format 1_1(第一DCI)配置上述TDRA表的情况下,当UE接收由CRC由CS-RNTI加扰且NDI=1或NDI=0的DCI format 1_1调度的PDSCH时,若PDSCH配置(pdsch-Config)中包括pdsch-AggregationFactor,不按该pdsch-AggregationFactor配置的次数重复。其中,若第一DCI采用其他DCI format(其他fomart对应的TDRA表和上述TDRA表不同,例如,其他fomart对应的TDRA表中的各行均只包括一个SLIV),例如DCI format 1_0/1_2等,则按该pdsch-AggregationFactor配置的次数重复。
在上述实施例中,在一个实施方式中,第一DCI调度的PDSCH不重复。无论SPS配置中是否包含上述pdsch-AggregationFactor。
在上述实施例中,在另一个实施方式中,如果SPS配置中包含上述pdsch-AggregationFactor,则第一DCI调度的PDSCH按照该pdsch-AggregationFactor重复。
在这个实施方式中,终端设备可以接收包括用于配置重复次数的第二配置参数(例如pdsch-AggregationFactor)的SPS配置;该第二配置参数应用于第一DCI。
在这个实施方式中,第二配置参数应用于第一DCI,是指:第二配置参数应用于第一DCI调度的PDSCH中的一个或多于一个。
例如,第一DCI调度的各PDSCH按照第二配置参数配置的次数重复,和/或,第一DCI调度的各有效的PDSCH按照第二配置参数配置的次数重复;和/或,第一DCI调度的PDSCH中的终端设备需接收的各PDSCH按照第二配置参数配置的次数重复;和/或,第一DCI仅调度一个PDSCH且该一个PDSCH按照第二配置参数配置的次数重复;和/或,第一DCI调度的PDSCH中终端设备仅接收一个PDSCH且该一个PDSCH按照第二配置参数配置的次数重复。
在这个实施方式中,SPS配置(sps-config)是该PDSCH(对应的SPS PDSCH)对应的SPS配置。例如,该UE仅配置了一个sps-config,则该sps-config即为该PDSCH(对应的SPS PDSCH)对应的SPS配置。再例如,若该UE仅配置并激活了多于一个SPS配置,UE例如根据该PDSCH对应的HARQ process ID确定该PDSCH(对应的SPS PDSCH)对应的SPS配置。再例如,在该PDSCH对应的HARQ process ID由多个SPS配置共享的情况下,上述pdsch-AggregationFactor例如是指多个SPS配 置中包括的最大的pdsch-AggregationFactor。
在本申请实施例中,SPS配置中还可以包括用于基站指示/UE确定相应的HARQ process ID范围的信息域(或字段),例如nrofHARQ-Processes、harq-ProcID-Offset等。
在本申请实施例中,对于SPS PDSCH的聚合/重复,在一些实施例中,终端设备还可以接收包括用于配置重复次数的第一配置参数(例如pdsch-AggregationFactor)的PDSCH配置(pdsch-Config);此外,终端设备还可以接收用于激活SPS配置的第二DCI,上述第一配置参数应用于该第二DCI,该第二DCI对应的TDRA表中的一行或多于一行包括多于一个SLIV。
在上述实施例中,第一配置参数应用于第二DCI,是指:第二DCI对应的SPS PDSCH按照上述第一配置参数重复。其中,第二DCI对应的SPS PDSCH例如是指由第二DCI激活的SPS配置调度的PDSCH(SPS PDSCH),或者说,由第二DCI激活的SPS PDSCH。
例如,在针对DCI format 1_1(第二DCI)配置上述TDRA表的情况下,针对由SPS配置调度且由DCI format 1_1激活的PDSCH(即SPS PDSCH),若PDSCH配置(pdsch-Config)中包括pdsch-AggregationFactor,按该pdsch-AggregationFactor配置的次数重复。SPS PDSCH没有对应的PDCCH,该PDCCH是承载用于调度PDSCH的DCI的PDCCH。
在本申请实施例中,对于SPS PDSCH的聚合/重复,在另一些实施例中,终端设备还可以接收包括用于配置重复次数的第一配置参数(例如pdsch-AggregationFactor)的PDSCH配置(pdsch-Config);此外,终端设备还可以接收用于激活SPS配置的第二DCI,上述第一配置参数不应用于该第二DCI,该第二DCI对应的TDRA表中的一行或多于一行包括多于一个SLIV。
在上述实施例中,第一配置参数不应用于第二DCI,是指:第一配置参数不应用于第二DCI对应的SPS PDSCH中的任一个。
例如,在针对DCI format 1_1(第二DCI)配置上述TDRA表的情况下,针对由SPS配置调度且由DCI format 1_1激活的PDSCH(即SPS PDSCH),若PDSCH配置(pdsch-Config)中包括pdsch-AggregationFactor,不按该pdsch-AggregationFactor配置的次数重复。SPS PDSCH没有对应的PDCCH,该PDCCH是承载用于调度PDSCH 的DCI的PDCCH。其中,若第二DCI采用其他DCI format(其他fomart对应的TDRA表和上述TDRA表不同,例如其他fomart对应的TDRA表中的各行均只包括一个SLIV),例如DCI format 1_0/1_2等,则按该pdsch-AggregationFactor配置的次数重复。
在上述实施例中,在一个实施方式中,第二DCI对应的SPS PDSCH不重复。无论SPS配置中是否包含上述pdsch-AggregationFactor。
在上述实施例中,在另一个实施方式中,如果SPS配置中包含上述pdsch-AggregationFactor,则第二DCI对应的SPS PDSCH按照该pdsch-AggregationFactor重复。
在这个实施方式中,终端设备可以接收包括用于配置重复次数的第二配置参数(例如pdsch-AggregationFactor)的SPS配置,该第二配置参数应用于第二DCI。
在这个实施方式中,第二配置参数应用于第二DCI,是指:第二配置参数应用于第二DCI对应的SPS PDSCH中的一个或多于一个。
例如,第二DCI对应的各SPS PDSCH按照第二配置参数配置的次数重复,和/或,第二DCI对应的各有效的SPS PDSCH按照第二配置参数配置的次数重复;和/或,第二DCI对应的SPS PDSCH中的终端设备需接收的各SPS PDSCH按照第二配置参数配置的次数重复;和/或,第二DCI仅对应一个SPS PDSCH且该一个SPS PDSCH按照第二配置参数配置的次数重复;和/或,第二DCI对应的SPS PDSCH中终端设备仅接收一个SPS PDSCH且该一个SPS PDSCH按照第二配置参数配置的次数重复。
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。
在本申请实施例中,终端设备还可以接收用于激活/去激活SPS的PDCCH/DCI,例如,终端设备可以至少根据以下一项或多项确认该PDCCH/DCI的有效性(validates the PDCCH):
1.采用CS-RNTI加扰(更具体地,相应DCI format的CRC采用CS-RNTI加扰)
2.NDI域设为‘0’;
3.如果有DFI域,设为“0”;

表2
此外,如果被提供了多于一个针对SPS PDSCH的配置,该DCI的有效性还取决于RV域,关于RV域设置的进一步解释和上述针对只有一个针对SPS PDSCH的配置的激活情况相同。如下面的表3所示。
表3
另一方面,(针对被提供了多于一个针对SPS PDSCH的配置的情况,)HARQ process number域用于指示该DCI激活的SPS配置索引。该SPS配置索引可以关联/对应一个或多个针对SPS PDSCH的配置。
在本申请实施例中,针对SPS去激活,如果只被提供了一个针对SPS PDSCH的配置(或者说,只配置了一个SPS PDSCH),该DCI的有效性还可能取决于HARQ process number域,RV域,Modulation and coding scheme域和Frequency domain resource assignment域。

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。
根据本申请实施例的方法,能够支持通过一个DCI调度多于一个PDSCH,进一步的,能够支持在一个DCI(或者说DCI format)可以调度多于一个PDSCH的情况下的半静态调度或半持续调度PDSCH,以及支持针对对应半静态调度或半持续调度的数据的动态重传。此外,对于网络设备来说,也可以提高配置及资源调度的灵活性。
第三方面的实施例
本申请实施例提供一种数据发送方法,从终端设备的一侧进行说明。
图4是本申请实施例的数据发送方法的一示意图。如图4所示,本申请实施例的数据发送方法包括:
401:终端设备接收第三下行控制信息,所述第三下行控制信息用于调度PUSCH;
402:所述终端设备发送所述第三下行控制信息调度的PUSCH中的一个或多于一个PUSCH。
根据本申请实施例,终端设备发送第三DCI调度的一个或多于一个PUSCH,由此,能够支持通过一个DCI调度多于一个PUSCH,进一步的,能够支持在一个DCI(或者说DCI format)可以调度多于一个PUSCH的情况下的半静态调度或半持续调度PUSCH,以及支持针对对应半静态调度或半持续调度的数据的动态重传。
在一些实施例中,在终端设备发送第三DCI调度的PUSCH中的多于一个PUSCH的情况下,该多于一个PUSCH中的不同的PUSCH承载的数据(也即传输块TB)不同。由此,能够支持通过一个DCI指示不同传输块的传输。
在一些实施例中,第三DCI是DCI format 0_1,也即,网络设备通过DCI format 0_1调度多个PUSCH。
在一些实施例中,第三DCI包括一个NDI(New Data Indication,新数据指示)域或者两个NDI域,在该第三DCI包括两个NDI域的情况下,各NDI域分别对应一个TB。例如,第三DCI包括第一NDI域和/或第二NDI域,在第三DCI包括第一 NDI域和第二NDI域的情况下,该第一NDI域和该第二NDI域分别对应第一个TB和第二个TB。由此,可以通过NDI域对TB进行指示。
在上述实施例中,第一NDI域和/或第二NDI域的值为0或者1。
在一些实施例中,在第三DCI的CRC由CS-RNTI加扰的情况下,第一NDI域和/或第二NDI域包括的比特数可以根据以下至少一项确定,即:
第三DCI可调度的PUSCH的最大数(也即,第三DCI对应的TDRA表中一行包括的SLIV的最大数);
第三DCI调度的PUSCH数(也即,第三DCI指示的行包括的SLIV数);
第三DCI调度调度有效的PUSCH数(也即,第三DCI指示的行包括的有效的SLIV数)。
由此,第一NDI域和/或第二NDI域可以包括一个比特,也可以包括多于一个比特,具体取决于上述至少一项决定因素。
在另一些实施例中,在第三DCI的CRC由CS-RNTI加扰的情况下,上述第一NDI域和/或第二NDI域只有1个比特。例如,当配置了2个TB时,第三DCI中包括1个NDI域,该NDI域为1个比特;或者,第三DCI中包括2个NDI域,且各TB对应的NDI域的比特数为1。在该实施例中,NDI域的比特数不取决于前述实施例中的决定因素。
在一些实施例中,第三DCI对应的TDRA表中的一行或多于一行包括多于一个SLIV,该多于一个SLIV对应多于一个PUSCH,由此实现了通过该第三DCI调度多于一个PUSCH。
在上述实施例中,在一些实施方式中,不采用上述第三DCI调度CG的重传,也即,终端设备不期望该第三DCI的CRC由CS-RNTI加扰;在一些实施方式中,第三DCI的第一NDI域和/或第二NDI域的值为1;在一些实施方式中,第三DCI调度多于一个PUSCH;在一些实施方式中,第三DCI调度多于一个有效的PUSCH;在一些实施方式中,第三DCI的NDI域(第一NDI域和/或第二NDI域)中包括多于一个值为1的比特;在一些实施方式中,第三DCI调度的多于一个PUSCH对应的HARQ进程ID是针对CG配置的一个或多于一个HARQ进程ID之一;在一些实施方式中,第三DCI调度的一个或多于一个PUSCH对应的HARQ进程ID不是针对CG配置的一个或多于一个HARQ进程ID之一。上述各实施方式可以分别实施,也可以任意组 合。
在上述实施例中,第一NDI域和/或第二NDI域的值为1,包括但不限于:
第一NDI域包括1个比特,该1个比特的值为1;或者,
第一NDI域包括多于1个比特,该第一NDI域的一个或多于一个特定比特的值为1,或者,该第一NDI域的至少1个比特的值为1,或者,该第一NDI域的所有比特的值为1;或者,
第二NDI域包括1个比特,该1个比特的值为1;或者,
第二NDI域包括多于1个比特,该第二NDI域的一个或多于一个特定比特的值为1,或者,该第二NDI域的至少1个比特的值为1,或者,该第二NDI域的所有比特的值为1。
在本申请实施例中,在一些实施例中,第三DCI的CRC由CS-RNTI加扰,该第三DCI仅调度一个PUSCH(也即,该第三DCI指示对应的TDRA表中包括一个SLIV的行),终端设备仅发送该一个PUSCH。
例如,在针对DCI format 0_1(第三DCI)配置上述TDRA表的情况下,若UE接收到CRC由CS-RNTI加扰且NDI=1(针对两个TB的情况,各TB分别对应一个NDI域,均为1或者其中一个(例如第一个TB)对应的NDI域为1)的DCI format 0_1,该DCI只能指示包括一个SLIV的行,不能指示包括多个SLIV的行。即,该DCI只能指示或调度一个PUSCH。
在这个例子中,该DCI中指示的HARQ process ID可以对应该PUSCH。该HARQ process ID可以在针对CG配置HARQ process组中,但是本申请不限于此,该DCI中指示的HARQ process ID也可以有其他实施方式,具体如前所述,此处省略说明。
在本申请实施例中,在一些实施例中,第三DCI的CRC由CS-RNTI加扰,该第三DCI调度多于一个PUSCH(也即,该第三DCI指示对应的TDRA表中包括多于一个SLIV的行)。
在上述实施例中,终端设备可以根据以下至少一项确定是否发送该第三DCI调度的多于一个PUSCH中的PUSCH:
PUSCH对应的HARQ process ID;
PUSCH对应的NDI域比特的值;
PUSCH是否和半静态配置的下行符号冲突;
PUSCH是否和SSB冲突;
PUSCH是否和CORESET#0冲突。
例如,根据PUSCH是否和半静态配置的上行符号冲突,终端设备仅发送上述多于一个PUSCH中的其中一个PUSCH。
在这个例子中,该一个PUSCH可以是上述多于一个PUSCH中的第一个PUSCH或最后一个PUSCH,也可以是上述多于一个PUSCH中唯一一个有效的PUSCH,还可以是上述多于一个PUSCH中唯一一个相应的NDI域的值为1的PUSCH,还可以是上述多于一个PUSCH中唯一一个对应的HARQ进程ID是针对CG配置的一个或多于HARQ进程ID之一的PUSCH。本申请不限于此,上述一个PUSCH还可以是其他或者上述任意组合。
在一些实施例中,SSB是指通过RRC信令(例如ssb-PositionsInBurst in SIB1或ssb-PositionsInBurst in ServingCelConfigCommon)配置的SSB。
在一些实施例中,CORECET#0是通过MIB配置的。
下面通过具体的示例对这个例子进行说明。
在针对DCI format 0_1(第三DCI)配置上述TDRA表的情况下,若UE接收到CRC由CS-RNTI加扰且NDI=1或‘1’s(针对两个TB的情况,各TB分别对应一个NDI域,均为1或‘1’s,或者其中一个(例如第一个TB)对应的NDI域为1或‘1’s)的DCI format 0_1且指示包括多个SLIV的行,即该DCI可以指示/调度多于一个PUSCH。UE仅发送其中一个PUSCH,例如按时间顺序的第一个PUSCH或最后一个PUSCH,和/或,唯一一个有效的PUSCH(例如不和半静态配置的上行符号冲突的PUSCH),和/或,唯一一个相应NDI比特为1的PUSCH,和/或对应的HARQ进程ID是针对CG配置的一个或多于HARQ进程ID之一的PUSCH。
在这个例子中,该第三DCI指示的HARQ进程ID可以对应上述一个PUSCH(无论该PUSCH是否是第一个PUSCH);或者,该第三DCI指示的HARQ进程ID对应上述多于一个PUSCH中第一个有效的PUSCH,终端设备根据该HARQ进程ID确定上述一个PUSCH对应的HARQ进程ID(无论该PUSCH是否是第一个PUSCH)。
在这个例子中,上述一个PUSCH对应的HARQ进程ID可以是针对CG配置的一个或多于一个HARQ进程ID之一,也即在针对CG配置的HARQ进程ID组中。
在这个例子中,上述一个PUSCH可以是有效的PUSCH。
在这个例子中,上述第一个PUSCH可以是上述第三DCI调度的第一个PUSCH或者是上述第三DCI调度的第一个有效的PUSCH;同理,上述述最后一个PUSCH可以是上述第三DCI调度的最后一个PUSCH或者是上述第三DCI调度的最后一个有效的PUSCH。其中,第三DCI调度的第一个PUSCH也即第三DCI指示的行中第一个SLIV对应的PUSCH(有效的PUSCH),同理,第三DCI调度的最后一个PUSCH也即第三DCI指示的行中最后一个SLIV对应的PUSCH(有效的PUSCH)。
在这个例子中,针对UE仅发送唯一一个有效的PUSCH,即该DCI指示/调度的PUSCH只能包括一个有效的PUSCH,也就是说,UE不期望该DCI中指示/调度多于一个有效的PUSCH。UE也就仅发送该一个PUSCH。
在这个例子中,针对UE仅发送唯一一个相应NDI比特为1的PUSCH,该DCI的NDI域中只包括一个值为1的比特,也就是说,UE不期望该DCI的NDI域中包括多于一个值为1的比特。UE也就仅发送该一个PUSCH。
在这个例子中,UE不发送无效的(invalid)PUSCH,且无效的PUSCH没有对应的HARQ process ID。
在这个例子中,针对其他(有效的)PUSCH(如果有),UE不发送,或者说取消其他(有效的)PUSCH发送。其他(有效的)PUSCH对应或不对应HARQ process ID(或者说,UE确定或不确定其他(有效的)PUSCH的HARQ process ID))。
再例如,根据PUSCH对应的HARQ process ID,终端设备仅发送对应的HARQ进程ID是针对CG配置的一个或多于一个HARQ进程ID之一的PUSCH。
下面通过具体的示例对这个例子进行说明。
在针对DCI format 0_1(第三DCI)配置上述TDRA表的情况下,若UE接收到CRC由CS-RNTI加扰且NDI=1或‘1’s(针对两个TB的情况,各TB分别对应一个NDI域,均为1或‘1’s,或者其中一个(例如第一个TB)对应的NDI域为1或‘1’s)的DCI format 0_1且指示包括多个SLIV的行,即该DCI可以指示/调度多于一个PUSCH。UE仅发送对应的HARQ process ID在针对CG配置的HARQ process组中的PUSCH。
在这个例子中,该DCI中指示的HARQ process ID对应第一个有效的PUSCH,UE根据该指示确定有效的PUSCH的HARQ process ID。
在这个例子中,UE不发送对应的HARQ process ID不在针对CG配置的HARQ process组中的PUSCH。
在这个例子中,UE不发送无效的PUSCH,且无效的PUSCH没有对应的HARQ process ID。
再例如,根据PUSCH对应的HARQ process ID,终端设备发送上述多于一个PUSCH中所有有效的PUSCH。
其中,在一个例子中,所有有效的PUSCH对应的HARQ进程ID必须都是针对CG配置的一个或多于一个HARQ进程ID之一。
下面通过具体的示例对这个例子进行说明。
在针对DCI format 0_1(第三DCI)配置上述TDRA表的情况下,若UE接收到CRC由CS-RNTI加扰且NDI=1或‘1’s(针对两个TB的情况,各TB分别对应一个NDI域,均为1或‘1’s,或者其中一个(例如第一个TB)对应的NDI域为1或‘1’s)的DCI format 0_1且指示包括多个SLIV的行,即该DCI可以指示/调度多于一个PUSCH。该DCI指示/调度的多于一个PUSCH中包括的有效的PUSCH(s)对应的HARQ process ID(s)必须都在针对CG配置的HARQ process组中。也就是说,UE不期望该DCI中指示/调度的任一个有效的PUSCH(s)对应的HARQ process ID(s)不在针对CG配置的HARQ process组中。
其中,在另一个例子中,对应的HARQ进程ID不为针对CG配置的一个或多于一个HARQ进程ID之一和/或对应的NDI域比特的值为0的PUSCH,为初传。
下面通过具体的示例对这个例子进行说明。
在针对DCI format 0_1(第三DCI)配置上述TDRA表的情况下,若UE接收到CRC由CS-RNTI加扰且NDI=1或‘1’s的DCI format 0_1且指示包括多个SLIV的行,即该DCI可以指示/调度多于一个PUSCH。UE发送所有有效的PUSCH(s),针对对应的HARQ process ID(s)不在针对CG配置HARQ process组中的PUSCH,UE视为初传。
在这个例子中,所有有效的PUSCH中的仅一个或至少一个PUSCH对应的HARQ进程ID是针对CG配置的一个或多于一个HARQ进程ID之一。也即,该DCI指示/调度的多于一个PUSCH中包括的有效的PUSCH(s)对应的HARQ process ID(s)的仅一个或至少一个在针对CG配置的HARQ process组中。其中,该HARQ process ID(s)对应的有效的PUSCH(s)为重传。
在上述两个例子中,该DCI指示的HARQ process ID对应第一个有效的PUSCH,UE根据该指示确定有效的PUSCHs的HARQ process ID。
在上述两个例子中,UE发送所有有效的PUSCH(s)。
再例如,根据PUSCH对应的NDI域比特的值,终端设备仅发送对应的NDI域的比特的值为1的PUSCH;或者,终端设备发送所有有效的PUSCH,并且,针对对应的NDI域的比特的值为1的PUSCH视为重传,针对对应的NDI域的比特的值为0的PUSCH视为初传。
下面通过具体的示例对这个例子进行说明。
在针对DCI format 0_1(第三DCI)配置上述TDRA表的情况下,若UE接收到CRC由CS-RNTI加扰的DCI format 0_1且指示包括多个SLIV的行,其中,一个或多个SLIV对应的NDI比特=1(针对两个TB的情况,各TB分别对应一个NDI域,该一个或多个SLIV在两个NDI域中的相应比特均为1,或者其中一个(例如第一个TB)中的相应比特为1),即该DCI可以指示/调度多于一个PUSCH,且其中一个或多个PUSCH对应的NDI比特=1。
在这个例子中,UE仅发送NDI比特=1对应的PUSCH,或者,UE发送所有有效的PUSCH(s),针对对应的NDI比特=0的PUSCH,UE视为初传。
在这个例子中,所有有效的PUSCH中的仅一个或至少一个PUSCH对应的NDI域的比特的值为1。
在本申请实施例中,在一些实施例中,终端设备还可以接收包括用于配置重复次数的第三配置参数(例如PUSCH-AggregationFactor)的PUSCH配置(PUSCH-Config),在第三DCI的CRC由CS-RNTI加扰的情况下,该第三配置参数应用于该第三DCI。也即,在针对DCI format 0_1(第三DCI)配置上述TDRA表的情况下,当UE发送由CRC由CS-RNTI加扰且NDI=1或NDI=0的DCI format 0_1调度的PUSCH时,若PUSCH配置(PUSCH-Config)中包括PUSCH-AggregationFactor,按该PUSCH-AggregationFactor配置的次数重复。
在上述实施例中,第三配置参数应用于第三DCI,是指:第三配置参数应用于第三DCI调度的PUSCH中的一个或多于一个PUSCH。
例如,第三DCI调度的各PUSCH按照第三配置参数配置的次数重复,和/或,第三DCI调度的各有效的PUSCH按照第三配置参数配置的次数重复;和/或,第三 DCI调度的PUSCH中的终端设备需发送的各PUSCH按照第三配置参数配置的次数重复;和/或,第三DCI仅调度一个PUSCH且该一个PUSCH按照第三配置参数配置的次数重复;和/或,第三DCI调度的PUSCH中终端设备仅发送一个PUSCH且该一个PUSCH按照第三配置参数配置的次数重复。
在本申请实施例中,在一些实施例中,终端设备还可以接收包括用于配置重复次数的第三配置参数(例如PUSCH-AggregationFactor)的PUSCH配置(PUSCH-Config),在第三DCI的CRC由CS-RNTI加扰的情况下,该第三配置参数不应用于该第三DCI。
在上述实施例中,第三配置参数不应用于第三DCI,是指:第三配置参数不应用于第三DCI调度的PUSCH中的任一个。
例如,在针对DCI format 0_1(第三DCI)配置上述TDRA表的情况下,当UE发送由CRC由CS-RNTI加扰且NDI=1或NDI=0的DCI format 0_1调度的PUSCH时,若PUSCH配置(PUSCH-Config)中包括PUSCH-AggregationFactor,不按该PUSCH-AggregationFactor配置的次数重复。其中,若第三DCI采用其他DCI format(其他fomart对应的TDRA表和上述TDRA表不同,例如其他fomart对应的TDRA表中的各行均只包括一个SLIV),例如DCI format 1_0/1_2等,则按该PUSCH-AggregationFactor配置的次数重复。
在上述实施例中,在一个实施方式中,第三DCI调度的PUSCH不重复。无论CG配置中是否包含上述PUSCH-AggregationFactor。
在上述实施例中,在另一个实施方式中,如果CG配置中包含上述PUSCH-AggregationFactor,则第三DCI调度的PUSCH按照该PUSCH-AggregationFactor重复。
在这个实施方式中,终端设备可以接收包括用于配置重复次数的第四配置参数(例如PUSCH-AggregationFactor)的CG配置;该第四配置参数应用于第三DCI。
在这个实施方式中,第四配置参数应用于第三DCI,是指:第四配置参数应用于第三DCI调度的PUSCH中的一个或多于一个。
例如,第三DCI调度的各PUSCH按照第四配置参数配置的次数重复,和/或,第三DCI调度的各有效的PUSCH按照第四配置参数配置的次数重复;和/或,第三DCI调度的PUSCH中的终端设备需发送的各PUSCH按照第四配置参数配置的次数重复;和/或,第三DCI仅调度一个PUSCH且该一个PUSCH按照第四配置参数配置 的次数重复;和/或,第三DCI调度的PUSCH中终端设备仅发送一个PUSCH且该一个PUSCH按照第四配置参数配置的次数重复。
在这个实施方式中,CG配置(CG-config)是该PUSCH(对应的CG PUSCH)对应的CG配置。例如,该UE仅配置了一个CG-config,则该CG-config即为该PUSCH(对应的CG PUSCH)对应的CG配置。再例如,若该UE仅配置并激活了多于一个CG配置,UE例如根据该PUSCH对应的HARQ process ID确定该PUSCH(对应的CG PUSCH)对应的CG配置。再例如,在该PUSCH对应的HARQ process ID由多个CG配置共享的情况下,上述PUSCH-AggregationFactor例如是指多个CG配置中包括的最大的PUSCH-AggregationFactor。
在本申请实施例中,CG配置中还可以包括用于基站指示/UE确定相应的HARQ process ID范围的信息域(或字段),例如nrofHARQ-Processes、harq-ProcID-Offset等。

例如,在针对DCI format 0_1(第四DCI)配置上述TDRA表的情况下,针对由CG配置调度且由DCI format 0_1激活的PUSCH(即CG PUSCH),若PUSCH配置(PUSCH-Config)中包括PUSCH-AggregationFactor,按该PUSCH-AggregationFactor配置的次数重复。CG PUSCH没有对应的PDCCH,该PDCCH是承载用于调度PUSCH的DCI的PDCCH。
在本申请实施例中,对于CG PUSCH的聚合/重复,在另一些实施例中,终端设备还可以接收包括用于配置重复次数的第三配置参数(例如PUSCH-AggregationFactor)的PUSCH配置(PUSCH-Config);此外,终端设备还可 以接收用于激活CG配置的第四DCI,上述第三配置参数不应用于该第四DCI,该第四DCI对应的TDRA表中的一行或多于一行包括多于一个SLIV。
在上述实施例中,第三配置参数不应用于第四DCI,是指:第三配置参数不应用于第四DCI对应的CG PUSCH中的任一个。
例如,在针对DCI format 0_1(第四DCI)配置上述TDRA表的情况下,针对由CG配置调度且由DCI format 0_1激活的PUSCH(即CG PUSCH),若PUSCH配置(PUSCH-Config)中包括PUSCH-AggregationFactor,不按该PUSCH-AggregationFactor配置的次数重复。CG PUSCH没有对应的PDCCH,该PDCCH是承载用于调度PUSCH的DCI的PDCCH。其中,若第四DCI采用其他DCI format(其他fomart对应的TDRA表和上述TDRA表不同,例如其他fomart对应的TDRA表中的各行均只包括一个SLIV),例如DCI format 1_0/1_2等,则按该PUSCH-AggregationFactor配置的次数重复。
在上述实施例中,在一个实施方式中,第四DCI对应的CG PUSCH不重复。无论CG配置中是否包含上述PUSCH-AggregationFactor。
在上述实施例中,在另一个实施方式中,如果CG配置中包含上述PUSCH-AggregationFactor,则第四DCI对应的CG PUSCH按照该PUSCH-AggregationFactor重复。
在这个实施方式中,终端设备可以接收包括用于配置重复次数的第四配置参数(例如PUSCH-AggregationFactor)的CG配置,该第四配置参数应用于第四DCI。
在这个实施方式中,第四配置参数应用于第四DCI,是指:第四配置参数应用于第四DCI对应的CG PUSCH中的一个或多于一个。
例如,第四DCI对应的各CG PUSCH按照第四配置参数配置的次数重复,和/或,第四DCI对应的各有效的CG PUSCH按照第四配置参数配置的次数重复;和/或,第四DCI对应的CG PUSCH中的终端设备需发送的各CG PUSCH按照第四配置参数配置的次数重复;和/或,第四DCI仅对应一个CG PUSCH且该一个CG PUSCH按照第四配置参数配置的次数重复;和/或,第四DCI对应的CG PUSCH中终端设备仅发送一个CG PUSCH且该一个CG PUSCH按照第四配置参数配置的次数重复。
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。
在本申请实施例中,终端设备还可以接收用于激活/去激活CG的PDCCH/DCI,例如,终端设备可以至少根据以下一项或多项确认该PDCCH/DCI的有效性(validates the PDCCH):

2.NDI域设为‘0’;
3.如果有DFI域,设为“0”;
4.针对激活,如果有PUSCH-to-HARQ_feedback timing indicator field,该域不能提供一个不能应用的值(an inapplicable value)(例如-1);

在本申请实施例中,针对CG激活,如果只被提供了一个针对CG PUSCH的配置,该DCI的有效性还可能取决于HARQ process number域和RV域。
其中,针对RV域,如果该DCI对应的DCI format(例如DCI format 1_1)应用的TDRA表包括至少一行包括多于一个SLIV配置的TDRA配置,在Time domain resource assignment域指示的TDRA配置仅包括/对应一个PDSCH的情况下,该DCI中对应一个TB的Redundancy version域包括2bits。在该DCI format配置一个TB的情况下,DCI中仅包括一个Redundancy version域,且该Redundancy version域的比特均设为‘0’或均设为‘1’。在该DCI format配置了两个TB的情况下,DCI中包括两个TB分别对应的Redundancy version域(一一对应),两个TB分别对应的Redundancy version域的比特均设为‘0’或均设为‘1’;或者,一个TB(例如第一个TB)的对应的Redundancy version域的比特均设为‘0’,另一个TB(例如第二个TB)的对应的Redundancy version域的比特均设为‘1’。例如,(CG仅支持一个TB的情况下,)第一个TB是enabled,第二个TB是disabled,则第一个TB的对应的Redundancy version域的比特均设为‘0’,第二个TB)的对应的Redundancy version域的比特均设为‘1’。再例如,(CG仅支持两个TB的情况下,)两个TB分别对应的Redundancy version域的比特均设为‘0’或均设为‘1’。如上面的表2所示。
此外,如果被提供了多于一个针对CG PUSCH的配置,该DCI的有效性还取决 于RV域,关于RV域设置的进一步解释和上述针对只有一个针对CG PUSCH的配置的激活情况相同。如上面的表3所示。
另一方面,(针对被提供了多于一个针对CG PUSCH的配置的情况,)HARQ process number域用于指示该DCI激活的CG配置索引。该CG配置索引可以关联/对应一个或多个针对CG PUSCH的配置。
在本申请实施例中,针对CG去激活,如果只被提供了一个针对CG PUSCH的配置(或者说,只配置了一个CG PUSCH),该DCI的有效性还可能取决于HARQ process number域,RV域,Modulation and coding scheme域和Frequency domain resource assignment域。
其中,针对RV域,如果该DCI对应的DCI format(例如DCI format 1_1)应用的TDRA表包括至少一行包括多于一个SLIV配置的TDRA配置,在该DCI指示的TDRA配置仅包括/对应一个PDSCH的情况下,该DCI中对应一个TB的Redundancy version域包括2比特。在该DCI format配置一个TB的情况下,DCI中仅包括一个Redundancy version域,且该Redundancy version域的比特均设为‘0’或均设为‘1’。在该DCI format配置了两个TB的情况下,DCI中包括两个TB分别对应的Redundancy version域(一一对应),两个TB分别对应的Redundancy version域的比特均设为‘0’或均设为‘1’。如上面的表4所示。
如果被提供了多于一个针对CG PUSCH的配置,该DCI的有效性还取决于RV域,Modulation and coding scheme域和Frequency domain resource assignment域,关于RV域设置的进一步解释和上述针对只有一个针对CG PUSCH的配置的去激活情况相同。如上面的表5所示。
另一方面,(针对被提供了多于一个针对CG PUSCH的配置的情况,)HARQ process number域用于指示该DCI去激活的CG配置索引。该CG配置索引可以关联/对应一个或多个针对CG PUSCH的配置。
