- RNTI radio network temporary identity
- CS-RNTI Configured Scheduling-RNTI
- the higher layer signaling will also configure the transmission period of the SPS PDSCH accordingly.
- the base station can activate an SPS configuration by sending a PDCCH indicating SPS activation.
- the PDCCH indicating SPS activation can notify the scheduling information of this SPS (including time domain, frequency domain resources, modulation and coding schemes) (Modulation and coding scheme, MCS) and other information), the terminal can determine the periodic SPS transmission opportunity according to the PDCCH indicating SPS activation and the SPS cycle pre-configured by higher-layer signaling, and perform SPS in each periodic SPS transmission opportunity Transmission (base station transmission, terminal reception).
- the base station can send a PDCCH (also known as SPS PDSCH release) indicating the release of downlink SPS resources, thereby indicating the release of resources for a certain SPS configuration, where it indicates the release of downlink SPS resources

(I.e. scheduling timing relationship);
- the PDSCH to HARQ-ACK feedback timing indication field in the DCI format indicates the number of time slots K1 between PDSCH and HARQ-ACK (i.e., feedback timing relationship), as shown in FIG. 1.
- DCI formats for scheduling PDSCH there are two DCI formats for scheduling PDSCH, one is a fallback DCI format (such as DCI format 1_0), and the other is a non-fallback DCI format (such as DCI format 1_1, 1_2, etc.).
- the K1 set corresponding to fallback DCI is fixed to ⁇ 1,2,3,4,5,6,7,8 ⁇
- the K1 set corresponding to non-fallback DCI format is the largest K1 set defined in the system (0-16
- the maximum 8 values selected in the integer value of) must contain at least the values in ⁇ 0,1,2,3,4,5,6,7 ⁇ .

Whether a non-fallback DCI contains the PDSCH to HARQ-ACK feedback timing indication field depends on the high-level signaling pre-configured several candidate K1 values for the terminal. When only one K1 value is configured, the DCI does not include the PDSCH to HARQ-ACK feedback timing indicator field, and the terminal uses this K1 value to fix the PDSCH, SPS PDSCH, and PDCCH that indicate the release of downlink SPS resources that require HARQ-ACK feedback.

- the difference is that it is assumed that there is an SPS PDSCH transmission corresponding to SPS configuration 5 in time slot n+2 and an SPS PDSCH corresponding to SPS configuration 4 overlaps in the time domain, as shown in Figure 4, then Similar to the situation in Example 1, for the SPS PDSCH corresponding to SPS configuration 4 with repeated transmissions, the 4 repeated transmissions are based on the SPS PDSCH (that is, the target SPS PDSCH) in time slot n+2 and the K1 corresponding to the SPS configuration.
- the SPS PDSCH corresponding to SPS configuration 5 will not Transmission also does not feedback HARQ-ACK, and does not affect the SPS PDSCH corresponding to SPS configuration 4 in time slot n+2, so the result of the HARQ-ACK transmission time slot of SPS PDSCH in configuration 4 is the same as that of Example 1. ,No longer.
- the difference is that it is assumed that there are overlaps between multiple SPSs in the time slot n+2, as shown in FIG. 4 SPS PDSCH, in the 4 repeated transmissions, based on the SPS PDSCH in time slot n+2 (ie target SPS PDSCH) and the K1 value corresponding to the SPS configuration, determine the HARQ-ACK of the SPS PDSCH of the repeated transmission SPS configuration 4
- the time slot where the feedback transmission is located is based on the end of the SPS and PDSCH corresponding to SPS configuration 4 in time slot n+2.
- the last UL time slot that overlaps with it is found based on the SCS transmitting PUCCH; this is because, although There is an SPS PDSCH corresponding to configuration 2 in time slot n+2, but since the SPS PDSCH corresponding to configuration 2 overlaps with the SPS corresponding to configuration 1, the SPS PDSCH corresponding to configuration 2 is actually based on the overlap rule between SPSs, and It does not belong to the SPS PDSCH that the terminal needs to receive, so there is no need to consider the overlap between this SPS PDSCH and the SPS PDSCH of the corresponding configuration 4 that is repeatedly transmitted, then in the time slot n+2, there is no correspondence smaller than the number 4.
- the SPS PDSCH of the SPS configuration overlaps with the SPS PDSCH of the corresponding SPS configuration 2, so that it can be determined that the SPS PDSCH of the corresponding SPS configuration 2 in the time slot n+3 is the last SPS PDSCH (that is, the target SPS PDSCH) that meets the conditions.

本公开涉及通信技术领域,尤其涉及一种混合自动重传应答消息传输资源的确定方法、装置及设备。
在第五代(5
th Generation,5G)新空口(New Radio,NR)系统中,支持半持续调度(Semi-Persistent Scheduling,SPS)物理下行共享信道(Physical Downlink Shared CHannel,PDSCH)传输,并且支持一个载波上配置多个SPS配置,一个SPS配置的最小周期可以为1ms。当配置了SPS传输时,高层信令会相应的配置SPS对应的无线网络临时标识(Radio Network Tempory Identity,RNTI);如配置调度-RNTI(Configured Scheduling-RNTI,CS-RNTI),用于加扰激活和去激活SPS传输的PDSCH,高层信令还会相应的配置SPS PDSCH的传输周期。当存在业务需要进行SPS传输时,基站可以通过发送指示SPS激活的PDCCH来激活一个SPS配置,指示SPS激活的PDCCH中可以通知这个SPS的调度信息(包括时域、频域资源、调制和编码方案(Modulation and coding scheme,MCS)等信息),终端按照指示SPS激活的PDCCH以及高层信令预先配置的SPS周期就可以确定周期性的SPS传输机会,在每个周期性的SPS传输机会中进行SPS传输(基站发送、终端接收)。当确定不再需要这个SPS配置或者需要更改SPS配置时,基站可以发送指示下行SPS资源释放的PDCCH(也称SPS PDSCH release),从而指示对某一个SPS配置释放资源,其中,指示下行SPS资源释放的PDCCH可以一次仅指示一个SPS配置进行资源释放,也可以同时指示多个SPS配置进行资源释放。
5G NR中支持灵活的定时关系。对于具有对应的物理下行控制信道 (Physical Downlink Control CHannel,PDCCH)的PDSCH(即dynamic PDCSH),承载其调度信息的物理下行控制信道指示PDSCH与PDCCH之间的调度定时关系(Scheduling timing)以及PDSCH到其对应的混合自动重传请求应答(Hybrid automatic repeat request acknowledgement,HARQ-ACK)之间的反馈定时关系(HARQ-ACK timing)。具体地,PDCCH所使用的下行控制信息(Downlink Control Information,DCI)格式中的时域资源分配指示域(Time Domain Resource Assignment,TDRA)指示PDSCH所在时隙与DCI所在时隙的时隙偏移K0(即调度定时关系);DCI格式中的PDSCH到HARQ-ACK反馈定时指示域指示PDSCH到HARQ-ACK之间的时隙个数K1(即反馈定时关系),如图1所示。
调度PDSCH的DCI有两种格式,一种是回退(fall back)DCI格式(如DCI格式1_0),另一种是非回退(non-fallback)DCI格式(如DCI格式1_1、1_2等)。其中,fallback DCI对应的K1集合固定为{1,2,3,4,5,6,7,8},non-fallback DCI格式对应的K1集合为系统中定义的最大K1集合(0-16中的整数值)中选择出的最多8个值,需要至少包含{0,1,2,3,4,5,6,7}中的值。K1可以通过DCI中的3比特HARQ-ACK时间指示域指示一个值给终端,因此该值可以是动态改变的。指示下行SPS资源释放的PDCCH也是需要进行HARQ-ACK反馈的,其反馈时序也是可以由PDCCH中的PDSCH到HARQ-ACK反馈定时指示域进行指示的。对于SPS PDSCH,其K1值也是可以通过指示SPS激活的PDCCH中的PDSCH到HARQ-ACK反馈定时指示域指示的,并且对后续周期性的每一次SPS传输都是用这个K1值确定HARQ-ACK反馈位置。
一个fallback DCI中总是包含3比特PDSCH到HARQ-ACK反馈定时指示域,用于指示取值为1-8的正整数中的一个K1值。一个non-fallback DCI中是否包含PDSCH到HARQ-ACK反馈定时指示域,取决于高层信令预先为终端配置了几个候选K1值。当仅配置了一个K1值时,DCI中不包含PDSCH到HARQ-ACK反馈定时指示域,终端固定使用这一个K1值对需要进行HARQ-ACK反馈的PDSCH、SPS PDSCH、指示下行SPS资源释放的PDCCH确定HARQ-ACK反馈时域位置;当配置了超过1个K1值时,DCI中包含
比特PDSCH到HARQ-ACK反馈定时指示域,指示PDSCH(包括 被激活的SPS PDSCH)或指示下行SPS资源释放的PDCCH的HARQ-ACK时间。对于传输结束在时隙n的PDSCH或指示下行SPS资源释放的PDCCH,其HARQ-ACK反馈在时隙n+K1中传输,其中,这里的时隙都是参考物理上行控制信道(Physical Uplink Control CHannel,PUCCH)传输所在的载波的子载波间隔(SubCarrier Spacing,SCS)定义的时隙(即PUCCH传输时隙,当DL和UL具有不同的SCS时),即K1=0参考点是与PDSCH或指示下行SPS资源释放的PDCCH重叠的最后一个PUCCH传输时隙;上述是以时隙为K1单位的情况,当K1单位为子时隙时,同理。
5G NR系统中支持半静态(semi-static)和动态(dynamic)两种HARQ-ACK码本(codebook)产生方式。所谓HARQ-ACK codebook即针对在同一个时域位置(如时隙或子时隙)或同一PUCCH上进行HARQ-ACK反馈的下行传输(包括PDSCH和指示下行SPS资源释放的PDCCH)产生的HARQ-ACK反馈序列。
Semi-static codebook可以根据K1集合中的HARQ-ACK定时器的值确定每个载波c上对应在同一个时隙(slot)或子时隙(sub-slot)n进行HARQ-ACK反馈的下行传输的位置集合Mc(也可以称为候选PDSCH位置集合),然后根据Mc即可以确定时隙或子时隙n中传输的HARQ-ACK codebook。具体的,根据每个K1值确定对应的在时隙或子时隙n进行HARQ-ACK反馈的时隙,在这些时隙中的每个时隙中,进一步根据预先配置的下行时域资源分配信息表(即TDRA表格)中的各种时域资源分配信息(即起始和长度指示值(Start and length indicator value,SLIV),每个SLIV提供了一个下行传输的起始符号和传输长度),确定一个时隙中时分复用(Time division multiplexing,TDM)存在的最大的下行传输的个数,例如,如果配置了半静态的上下行时隙结构,当根据一个SLIV确定的在一个时隙中的这个SLIV所指示的符号集合中存在上行符号,则该SLIV不能用作下行传输,因为存在上下行资源冲突,该下行传输实际不会发生,只有满足一个时隙中根据SLIV确定的符号集合中不包含上行符号,例如都为下行和/或灵活(Flexible)符号时,才说明该SLIV对应的下行传输可以在该时隙中存在,其中如果存在SLIV之间的重叠,重叠的SLIV中只会选择一个SLIV调度一个下行传输,而其他SLIV则不可用, 因此根据SLIV重叠的规则,可以从TDRA表格中的所有SLIV中分成多个SLIV组,每个SLIV组认为存在一个下行传输,从而确定出在一个时隙中可能存在的最大的TDM传输的下行传输个数,以此类推,确定出根据K1得到的对应在时隙或子时隙n中进行HARQ-ACK反馈的多个slot中每个slot中的下行传输格式,将多个slot中的总的下行传输个数作为Mc,根据Mc确定在时隙或子时隙n中传输的semi-static HARQ-ACK码本,包括码本的大小和HARQ-ACK具体内容和顺序。
在支持配置多个SPS配置的情况下,不同SPS配置下的SPS PDSCH的HARQ-ACK可以在同一个PUCCH上进行复用传输。考虑到不同的SPS配置由于周期和具体资源分配不同,可能会导致在部分时隙中,存在多个SPS配置对应的SPS PDSCH之间的时域资源存在重叠,而SPS还可以被配置进行重复传输,当被配置进行重复传输的SPS与其他SPS重叠时,如何进行重复传输的SPS的HARQ-ACK反馈还没有明确的方法。

本公开的上述实施例,对于配置了重复传输的对应SPS配置索引i的SPS PDSCH,根据K次重复传输中的最后一次不与对应SPS配置索引j的SPS PDSCH存在时域重叠的SPS PDSCH,确定重复传输的SPS PDSCH的HARQ-ACK传输所在的时间单元,所述j小于i,所述时间单元为预定的A个符号(比如正交频分复用(Orthogonal frequency division multiplex,OFDM)符号),或为一个时隙(Slot),或为一个子时隙。从而实现了被配置进行重复传输的SPS与其他SPS重叠时,可以进行重复传输的SPS的HARQ-ACK反馈。

1)在重叠的SPS PDSCH中确定的需要接收的SPS PDSCH;
2)根据终端的单播PDSCH接收能力确定的需要接收的SPS PDSCH。
其中,在重叠的SPS PDSCH中确定的需要接收的SPS PDSCH为候选SPS PDSCH,所述候选SPS PDSCH通过以下方式得到(下述方式仅为示例,不排除其他预先定义好的从存在重叠的SPS PDSCH中确定出需要接收的SPS PDSCH的方式,这里需要明确的是,如果存在SPS之间的重叠,对应SPS配置索引j的SPS PDSCH并不是任何一个SPS,而是根据对重叠的SPS之间的处理规则得到的,在重叠的SPS之间是可以传输的SPS,这是因为重叠的资源上只能有一个传输,那么重叠的SPS中必然有一部分是可以传输的,而另一部是由于资源冲突而不可以传输的,这里的对应SPS配置索引j的SPS PDSCH并不是哪些由于资源冲突而已经判断不可以传输的SPS PDSCH):
步骤111),将一个时隙中的所有SPS PDSCH作为一个集合Q,在集合中找到对应最小SPS配置索引的SPS PDSCH,作为候选SPS PDSCH;
步骤112),去掉所述集合中与候选SPS PDSCH在时域上存在重叠的SPS PDSCH以及候选SPS PDSCH,得到更新的集合Q’;
步骤113),针对更新的集合Q’,重复上述步骤111)和步骤112),直到集合Q为空,得到集合Q中所有的候选SPS PDSCH。
其中,根据终端的单播PDSCH接收能力确定需要接收的SPS PDSCH包括以下211)和212)中的至少一种(下述方式仅为示例,不排除其他预先定义好的根据终端能力从一个时隙中包含的所有SPS PDSCH中确定出需要接收的SPS PDSCH的方式,这里需要明确的是,如果一个时隙中存在多个SPS,对应SPS配置索引j的SPS PDSCH并不是任何一个SPS,而是在终端接收能力受限时(比如这个时隙中存在的SPS个数比终端在一个时隙中能够接收的最大单播PDSCH个数还多),根据终端接收能力,按照特定规则选择出的不超过接收能力的这个时隙中的部分SPS,这里的对应SPS配置索引j的SPS PDSCH并不是哪些由于终端接收能力受限,根据特定规则而已经判断不可以被接收的SPS PDSCH):
211)当终端在一个时隙中仅支持接收一个单播PDSCH时,将当前时隙中对应最低SPS配置索引的SPS PDSCH作为需要接收的SPS PDSCH;
212)当终端在一个时隙中支持接收超过一个单播PDSCH时,进一步可 以使用如下方式中的一种:
2121)、如果SPS之间没有重叠,将当前时隙中按照SPS配置索引从低到高的顺序,选择N个SPS PDSCH作为需要接收的SPS PDSCH,其中N为终端在一个时隙中能够接收的单播PDSCH的个数;即根据终端的单播PDSCH接收能力确定的能够最大接收的单播PDSCH的个数(其中PDSCH包含具有DCI调度的PDSCH和SPS PDSCH);
2122)、如果SPS之间存在重叠,则在重叠的SPS PDSCH中先确定需要接收的SPS PDSCH,然后再按照SPS配置索引从低到高的顺序,选择N个SPS PDSCH作为需要接收的SPS PDSCH,其中N为终端在一个时隙中能够接收的单播PDSCH的个数;即根据终端的单播PDSCH接收能力确定的能够最大接收的单播PDSCH的个数(其中PDSCH包含具有DCI调度的PDSCH和SPS PDSCH);
2123)、步骤1:将一个时隙中的所有SPS PDSCH作为一个集合Q,在集合中找到对应最小SPS配置索引的SPS PDSCH,作为候选SPS PDSCH;步骤2:去掉所述集合中与候选SPS PDSCH在时域上存在重叠的SPS PDSCH以及候选SPS PDSCH,得到更新的集合Q’;步骤3:针对更新的集合Q’,重复上述步骤1和步骤2,直到集合Q为空,得到集合Q中所有的候选SPS PDSCH,在所述候选SPS PDSCH中,按照SPS配置索引从低到高的顺序,选择N个SPS PDSCH作为需要接收的SPS PDSCH;
2124)、步骤1:将一个时隙中的所有SPS PDSCH作为一个集合Q,在集合中找到对应最小SPS配置索引的SPS PDSCH,作为候选SPS PDSCH;步骤2:去掉所述集合中与候选SPS PDSCH在时域上存在重叠的SPS PDSCH以及候选SPS PDSCH,得到更新的集合Q’;步骤3:针对更新的集合Q’,重复上述步骤1和步骤2,直到集合Q为空或者判断累计选择出的候选SPS PDSCH的个数为N个时,结束判断,并将累计选择的N个候选SPS PDSCH作为需要接收的SPS PDSCH。
如果在当前时隙中,没有SPS之间的重叠,SPS的个数也不超过终端的接收能力,则这个时隙中的SPS都可以作为对应SPS配置索引j的SPS PDSCH;如果在当前时隙中,存在SPS之间的重叠,但SPS的个数不超过终端的接收 能力,那么对应SPS配置索引j的SPS PDSCH为在重叠的SPS PDSCH中确定的需要接收的SPS PDSCH,即根据上述步骤111-113得到候选SPS PDSCH;如果在当前时隙中,不存在SPS之间的重叠,但SPS的个数超过终端的接收能力,那么对应SPS配置索引j的SPS PDSCH为根据终端的单播PDSCH接收能力确定的需要接收的SPS PDSCH,即根据上述步骤211和/或212得到的SPS PDSCH;如果在当前时隙中,既存在SPS之间的重叠,且SPS的个数也超过终端的接收能力,那么对应SPS配置索引j的SPS PDSCH为:在重叠的SPS PDSCH中确定的需要接收的SPS PDSCH中,进一步根据终端的单播PDSCH接收能力确定的需要接收的SPS PDSCH,即上述两种方式都执行之后得到的SPS PDSCH。
本公开的上述实施例中,重复传输的SPS PDSCH的HARQ-ACK为K次重复传输中,到所述目标SPS PDSCH为止的重复传输的SPS PDSCH合并之后得到的HARQ-ACK。即如果配置SPS PDSCH的重复传输次数为K次,如果所述目标SPS PDSCH为其中的K-1次,那么重复传输的SPS PDSCH的HARQ-ACK为K-1SPS PDSCH传输机会中接收到的SPS PDSCH合并之后得到的HARQ-ACK,即为重复传输实际的HARQ-ACK。
本公开的上述实施例中,重复传输的SPS PDSCH的HARQ-ACK映射到HARQ-ACK传输所在的时间单元中的对应于SPS PDSCH的HARQ-ACK码本中的对应于所述目标SPS PDSCH传输所在的时隙的HARQ-ACK位置。即如果根据K1集合={1,2,3,4}确定时隙n、n+1、n+2、n+3都需要在时隙n+4中的同一个HARQ-ACK码本中进行SPS PDSCH的HARQ-ACK反馈,如果对应SPS配置1的SPS PDSCH为在时隙n、n+1、n+2、n+3中进行4次重复传输的SPS,且确定4次重复传输中的目标SPS PDSCH为时隙n+2中的SPS PDSCH,时隙n、n+1和n+3中分别存在对应其他SPS配置的SPS PDSCH传输也需要在时隙n+4中的同一个HARQ-ACK码本重传输HARQ-ACK,则时隙n+4中的HARQ-ACK码本是需要对时隙n、n+1、n+2和n+3都预留HARQ-ACK反馈位置的,对于对应SPS配置1的进行4次重复传输的SPS PDSCH,虽然时隙n、n+1、n+3中也包含这个SPS PDSCH的传输机会,但由于目标SPS PDSCH是时隙n+2中的SPS PDSCH,则重复传输的SPS配置 1的SPS PDSCH的HARQ-ACK是映射到时隙n+4中的HARQ-ACK码本中对应于时隙n+2的HARQ-ACK位置,即如果时隙n到n+3中每个时隙对应1比特HARQ-ACK,HARQ-ACK码本包括4比特HARQ-ACK,从第一比特到最后一比特分别对应时隙n到时隙n+3中的每一个时隙(即第1比特对应时隙n,第2比特对应时隙n+1,第3比特对应时隙n+2,第4比特对应时隙n+3),则重复传输的SPS配置1的SPS PDSCH的HARQ-ACK是映射到HARQ-ACK码本中的第3比特HARQ-ACK的位置的。
本公开的上述实施例中,如果所述目标SPS PDSCH传输所在的时隙中包含多个HARQ-ACK位置,重复传输的SPS PDSCH的HARQ-ACK映射到HARQ-ACK码本中与所述目标SPS PDSCH对应的HARQ-ACK位置;其中与所述目标SPS PDSCH对应的HARQ-ACK位置即:根据所述目标SPS PDSCH对应的SPS配置索引确定的HARQ-ACK位置,其中,所述时隙对应的多个HARQ-ACK位置是按照该时隙中的多个SPS PDSCH对应的SPS配置索引的从小到大或者从大到小顺序排列的。即如果根据K1集合={1,2,3,4}确定时隙n、n+1、n+2、n+3都需要在时隙n+4中的同一个HARQ-ACK码本中进行SPS PDSCH的HARQ-ACK反馈,如果对应SPS配置1的SPS PDSCH为在时隙n、n+1、n+2、n+3中进行4次重复传输的SPS,且确定4次重复传输中的目标SPS PDSCH为时隙n+2中的SPS PDSCH,时隙n、n+1和n+3中分别存在对应其他SPS配置的SPS PDSCH传输也需要在时隙n+4中的同一个HARQ-ACK码本重传输HARQ-ACK,则时隙n+4中的HARQ-ACK码本是需要对时隙n、n+1、n+2和n+3都预留HARQ-ACK反馈位置的,对于对应SPS配置1的进行4次重复传输的SPS PDSCH,虽然时隙n、n+1、n+3中也包含这个SPS PDSCH的传输机会,但由于目标SPS PDSCH是时隙n+2中的SPS PDSCH,则重复传输的SPS配置1的SPS PDSCH的HARQ-ACK是映射到时隙n+4中的HARQ-ACK码本中对应于时隙n+2的HARQ-ACK位置,即如果假设时隙n到n+3中每个时隙对应2比特HARQ-ACK(即每个时隙中都包含2个可能的下行传输位置,即有两组SLIV),HARQ-ACK码本包括8比特HARQ-ACK,从第一比特到最后一比特每2比特分别对应时隙n到时隙n+3中的每一个时隙(即第1、2比特对应时隙n,第3、4比特对应时 隙n+1,第5、6比特对应时隙n+2,第7、8比特对应时隙n+3),则如果假设目标SPS PDSCH对应的SLIV在时隙n+2中的两个SLIV组中对应的是第一个SLIV组(即两个可能的下行传输位置中对应第一个下行传输位置),则重复传输的SPS配置1的SPS PDSCH的HARQ-ACK是映射到HARQ-ACK码本中的第5比特HARQ-ACK的位置的,如果假设目标SPS PDSCH对应的SLIV在时隙n+2中的两个SLIV组中对应的是第2个SLIV组(即两个可能的下行传输位置中对应第2个下行传输位置),则重复传输的SPS配置1的SPS PDSCH的HARQ-ACK是映射到HARQ-ACK码本中的第6比特HARQ-ACK的位置的。
本公开的上述实施例中,对于所述重复传输的SPS PDSCH中不是所述目标SPS PDSCH的SPS PDSCH,不进行HARQ-ACK反馈。即如果根据K1集合={1,2,3,4}确定时隙n、n+1、n+2、n+3都需要在时隙n+4中的同一个HARQ-ACK码本中进行SPS PDSCH的HARQ-ACK反馈,如果对应SPS配置1的SPS PDSCH为在时隙n、n+1、n+2、n+3中进行4次重复传输的SPS,且确定4次重复传输中的目标SPS PDSCH为时隙n+2中的SPS PDSCH,时隙n、n+1和n+3中分别存在对应其他SPS配置的SPS PDSCH传输也需要在时隙n+4中的同一个HARQ-ACK码本重传输HARQ-ACK,则时隙n+4中的HARQ-ACK码本是需要对时隙n、n+1、n+2和n+3都预留HARQ-ACK反馈位置的,对于对应SPS配置1的进行4次重复传输的SPS PDSCH,虽然时隙n、n+1、n+3中也包含这个SPS PDSCH的传输机会,但在HARQ-ACK码本中,并不需要对这些SPS PDSCH传输机会预留HARQ-ACK反馈的位置,因为并不需要对这些SPS PDSCH反馈HARQ-ACK。
本公开的上述实施例中,当满足如下条件的至少一个时,可以执行上述步骤21和22来确定目标SPS PDSCH并基于目标SPS PDSCH确定HARQ-ACK传输的时间单元(即如果不满足下述条件,可以不采用本公开的方式确定重复传输的SPS PDSCH的HARQ-ACK传输的时间单元;当然,也不排除不需要进行下述条件的判断,对任何SPS传输情况,总是使用本公开的方式确定重复传输的SPS PDSCH的HARQ-ACK传输的时间单元):
当配置了重复传输的SPS PDSCH在重复传输的时隙中的至少一个时隙 或最后一个时隙中与其他SPS PDSCH存在时域重叠;
当配置了重复传输且对应SPS配置索引i的SPS PDSCH,在重复传输的时隙中的至少一个时隙或最后一个时隙中与对应SPS配置索引j的SPS PDSCH存在时域重叠;
在传输HARQ-ACK的时间单元中,仅存在对应SPS PDSCH的HARQ-ACK传输,或,在配置使用动态HARQ-ACK码本时,对应SPS PDSCH的HARQ-ACK,与对应具有DCI调度的PDSCH或指示下行SPS资源释放的PDCCH的HARQ-ACK进行复用传输。
本公开的一可选的实施例中,对于配置了重复传输的对应半持续调度SPS配置索引i的半持续调度物理下行共享信道SPS PDSCH,确定所述SPS PDSCH重复传输中的一个目标SPS PDSCH,包括以下至少一项:
1)当配置了重复传输的SPS PDSCH在重复传输的时隙中的至少一个时隙或最后一个时隙中与其他SPS PDSCH存在时域重叠时,对于配置了重复传输的对应半持续调度SPS配置索引i的半持续调度物理下行共享信道SPS PDSCH,确定所述SPS PDSCH重复传输中的一个目标SPS PDSCH;
2)当配置了重复传输且对应SPS配置索引i的SPS PDSCH,在重复传输的时隙中的至少一个时隙或最后一个时隙中与对应SPS配置索引j的SPS PDSCH存在时域重叠时,对于配置了重复传输的对应半持续调度SPS配置索引i的半持续调度物理下行共享信道SPS PDSCH,确定所述SPS PDSCH重复传输中的一个目标SPS PDSCH;
3)在传输HARQ-ACK的时间单元中,仅存在对应SPS PDSCH的HARQ-ACK传输,或,在配置使用动态HARQ-ACK码本时,对应SPS PDSCH的HARQ-ACK,与对应具有下行控制信息DCI调度的PDSCH或指示下行SPS资源释放的PDCCH的HARQ-ACK进行复用传输时,对于配置了重复传输的对应半持续调度SPS配置索引i的半持续调度物理下行共享信道SPS PDSCH,确定所述SPS PDSCH重复传输中的一个目标SPS PDSCH。
具体实现时,如以下实施例1:如图3所示,时隙n到n+3为对应SPS配置4的SPS PDSCH进行K=4次重复传输的时隙,其中重复传输的最后一个时隙(即时隙n+3)中对应SPS配置4(即i=4)的SPS PDSCH与对应SPS 配置3(即j=3)的SPS PDSCH在时域上存在资源重叠,而在时隙n+2中,对应SPS配置4的SPS PDSCH在时域上不与任何其他SPS PDSCH存在重叠,则根据本公开方法,对于采用重复传输的对应SPS配置4的SPS PDSCH,在4次重复传输中是基于时隙n+2中的SPS PDSCH(即目标SPS PDSCH)以及SPS配置对应的K1值,确定重复传输的SPS配置4的SPS PDSCH的HARQ-ACK反馈传输所在的时隙的,即基于时隙n+2中的对应SPS配置4的SPS PDSCH的结束为止找到与之重叠的传输PUCCH的UL时隙(即根据UL的SCS划分的时隙),本实施例中,由于UL和DL的SCS相同,因此UL和DL的时隙划分是对齐的,因此找到的是UL时隙n+2,以UL时隙n+2作为K1=0时的参考点(即UL时隙n+2即为K1=0是对应的UL时隙),可以得到K1=1时对应的UL时隙n+3,从而确定重复传输的对应SPS配置4的SPS PDSCH的HARQ-ACK反馈是在时隙n+3中传输,其中HARQ-ACK是时隙n、n+1和n+2中重复传输的3次SPS PDSCH的信息合并之后译码得到的HARQ-ACK(即这个HARQ-ACK是用来表示重复传输中,到用于确定HARQ-ACK反馈位置的SPS PDSCH位置的所有重复的SPS PDSCH合并之后的有效HARQ-ACK,从而体现出重复传输的增益),从而避免了按照相关技术根据4次重复传输中的第4次重复传输以及K1确定HARQ-ACK的传输时隙中,由于第4次重复传输(即时隙n+3中的传输)与另一个对应SPS配置索引编号更低的SPS PDSCH存在时域资源重叠,而导致在反馈传输的时隙n+4中的HARQ-ACK码本中并包含对应SPS配置4的SPS PDSCH的HARQ-ACK传输,从而导致对应SPS配置4的SPS PDSCH的HARQ-ACK不能上报的问题。其中,时隙n+3中的SPS HARQ-ACK码本中,不需要包含时隙n和n+1中对应SPS配置4的SPS PDSCH的HARQ-ACK,即即使此时K1集合={1,2,3},即根据K1集合的范围,基于时隙n+3,可以推断出时隙n、n+1和n+2中都可能存在SPS可以在时隙n+3中进行HARQ-ACK反馈,但如果时隙n和n+1中仅包含重复传输的SPS PDSCH中不是用来确定反馈时的目标SPS PDSCH,则由于重复传输的多个SPS PDSCH最终的HARQ-ACK已经在用来确定反馈时的目标SPS PDSCH对应的HARQ-ACK位置上传输了,则同一个HARQ-ACK码本中就不需要对其他不是目标SPS PDSCH的SPS PDSCH预留HARQ-ACK反馈位置了,即在假设K1集合={1,2,3}时,时隙n+3中的SPS HARQ-ACK码本中对应于图3的情况,仅包含对应时隙n+2中的SPS配置4的SPS PDSCH的1比特HARQ-ACK反馈就够了。当然,也不排除时隙n+3中的SPS HARQ-ACK码本可以对根据K1set确定的可能在时隙n+3中进行HARQ-ACK反馈的所有时隙中的重复传输的SPS PDSCH都预留HARQ-ACK,则对应于图3情况,时隙n+3中的SPS HARQ-ACK码本可以包含3比特HARQ-ACK,分别对应于时隙n、n+1和n+2中的对应SPS配置4的SPS PDSCH,但这样就会存在一定的冗余(实际上时隙n和n+1中的SPS PDSCH的HARQ-ACK没必要反馈)。
本公开的一可选的实施例中,混合自动重传应答消息的传输资源的确定方法还可以包括:对于所述重复传输的SPS PDSCH中不是所述目标SPS PDSCH的SPS PDSCH,不进行HARQ-ACK反馈。
具体实现实例如下实施例2:
类似上述实施例1,所不同的是假设时隙n+2中还存在一个对应SPS配置5的SPS PDSCH传输与对应SPS配置4的SPS PDSCH在时域上存在重叠,如图4所示,则类似实施例1中的情况,对于采用重复传输的对应SPS配置4的SPS PDSCH,在4次重复传输中是基于时隙n+2中的SPS PDSCH(即目标SPS PDSCH)以及SPS配置对应的K1值,确定重复传输的SPS配置4的SPS PDSCH的HARQ-ACK反馈传输所在的时隙的,即基于时隙n+2中的对应SPS配置4的SPS PDSCH的结束为止找到与之重叠的根据传输PUCCH的SCS确定的最后一个UL时隙;这是因为,虽然时隙n+2中存在一个与对应SPS配置4的SPS PDSCH重叠的SPS PDSCH,但由于这个SPS PDSCH对应的SPS配置的索引是5,比SPS配置4的索引大,因此对应SPS配置5的SPS PDSCH是会被对应SPS配置4的SPS PDSCH所停止的,即在这样的时域重叠下,是对应SPS配置5的SPS PDSCH不会传输也不会反馈HARQ-ACK,并不影响时隙n+2中的对应SPS配置4的SPS PDSCH,所以得到的配置4的SPS PDSCH的HARQ-ACK传输时隙的结果是同实施例1的,不再赘述。
实施例3:
类似上述实施例1,所不同的是假设时隙n+2中存在多个SPS之间的相 互重叠,如图5所示,则类似实施例1中的情况,对于采用重复传输的对应SPS配置4的SPS PDSCH,在4次重复传输中是基于时隙n+2中的SPS PDSCH(即目标SPS PDSCH)以及SPS配置对应的K1值,确定重复传输的SPS配置4的SPS PDSCH的HARQ-ACK反馈传输所在的时隙的,即基于时隙n+2中的对应SPS配置4的SPS PDSCH的结束为止找到与之重叠的根据传输PUCCH的SCS确定的最后一个UL时隙;这是因为,虽然时隙n+2中存在对应配置2的SPS PDSCH,但由于这个对应配置2的SPS PDSCH与对应配置1的SPS重叠,则这个对应配置2的SPS PDSCH实际上根据SPS之间的重叠规则,并不属于终端需要接收的SPS PDSCH,因此并不需要考虑这个SPS PDSCH与重复传输的对应配置4的SPS PDSCH之间的重叠,那么在时隙n+2中,就不存在一个对应比编号4小的SPS配置的SPS PDSCH与对应SPS配置2的SPS PDSCH重叠,从而可以确定时隙n+3中的对应SPS配置2的SPS PDSCH即为最后一个满足条件的SPS PDSCH(即目标SPS PDSCH),从而得到的HARQ-ACK传输时隙的结果是同实施例1的,不再赘述。
上述实施例中仅以UL和DL的SCS相同、单载波的情况为例,SCS不同、多载波聚合等情况下同样适用;上述实施例中仅以时隙为单位的传输为了,当K1的单位为子时隙或者其他预定的时间单元长度时,同样适用;上述实施例中,在时隙n+3中,是否存在对应SPS配置1的SPS PDSCH传输并不影响本实施例的判断结果,因为这个SPS配置对应的SPS PDSCH的时域资源并不与对应SPS配置4的SPS PDSCH以及其他SPS PDSCH的时域资源重叠。
本公开的上述实施例中,当SPS PDSCH进行重复传输时,根据K次重复传输中的最后一次不与对应SPS配置索引j的SPS PDSCH存在时域重叠的SPS PDSCH,确定重复传输的SPS PDSCH的HARQ-ACK传输所在的时间单元。保证PDSCH重复传输时可以正常的进行HARQ-ACK反馈,避免按照重复传输中的最后一次传输确定反馈时序时,由于重复传输的SPS PDSCH与其他SPS PDSCH的冲突导致这个重复传输的SPS PDSCH无法进行HARQ-ACK反馈。
