具体实施方式
本申请的实施方式部分使用的术语仅用于对本申请的具体实施例进行解释,而非旨在限定本申请。
在对本申请实施例进行介绍之前,首先对现有技术的问题进行说明。在较早的3GPP协议版本中,如果不同优先级的HARQ-ACK的资源发生重叠,则低优先级的HARQ-ACK的传输会被丢弃,基于此,为了提高网络调度灵活性,提出了不同优先级的HARQ-ACK的资源发生重叠时,复用资源来传输。如果不同优先级的HARQ-ACK发生复用,并且在同一个PUCCH上传输,且总的上行控制信息(Uplink control information,UCI)比特数大于2时,两组HARQ-ACK可通过独立编码或者联合编码后在PUCCH上传输,采用联合编码复杂度较低,但是如果低优先级的HARQ-ACK译码出错,那么高优先级的HARQ-ACK译码也会出错。采用高低优先级分别编码会提升编码复杂度,但是如果低优先级的HARQ-ACK译码出错,高优先级的HARQ-ACK译码性能可能不受影响或者受影响较小。目前对于动态码本,可通过DCI中的字段指示码本的总total下行链路指派索引(Downlink assignment index,DAI),在对码本进行编码时,需要确定码本的大小,而total DAI可以用于确定码本的大小,如果最后一个DCI漏检,会使基站和终端对码本大小的理解不一致,导致UCI译码出错。例如对于用于指示HARQ-ACK的消息中,假设倒数第二个DCI中的total DAI为5,最后一个DCI中的total DAI为6,如果最后一个DCI漏检,那么可能会导致基站会认为码本大小为6bit(1个码字),用户侧设备(user equipment,UE)则认为是5bit,如果UE按照5比特进行编码,但是基站按照6比特进行译码,则基站会出现译码错误,导致HARQ-ACK的传输性能下降。针对不同优先级的HARQ-ACK的传输,为了保证两组HARQ-ACK的译码准确性,需要分别获取两组HARQ-ACK对应的total DAI,以确定码本大小,但是低优先级的最后一个DCI容易漏检,使基站和UE对于码本的大小理解不一致,从而导致译码错误,并且,无论采 用联合编码还是独立编码,低优先级的UCI译码错误都会影响高优先级的UCI的译码性能,即当不同优先级的HARQ-ACK的资源发生重叠时,传输性能会降低。为了解决上述问题,提供了本申请实施例,以下对本申请实施例的技术方案进行说明。
如图1和图2所示,本申请实施例提供一种混合自适应重传请求-确认HARQ-ACK传输方法,该方法可以用于高可靠低时延通信(ultra-reliable low latency communications,URLLC)中,包括:
步骤101、在至少一个小区cell对应的用于指示同一个上行时隙slot的多个下行控制信息DCI中,获取最后一个高优先级DCI中的至少部分字段,至少部分字段用于指示指定低优先级DCI的总total下行链路指派索引DAI;
步骤102、生成高优先级的码本以及根据指定低优先级DCI的total DAI生成低优先级的码本;
步骤103、根据低优先级的码本和所述高优先级的码本对低优先级HARQ-ACK和高优先级HARQ-ACK进行编码;
步骤104、传输编码后的所述低优先级HARQ-ACK和高优先级HARQ-ACK。
具体地,例如,以配置两个小区为例,步骤101中的至少一个小区包括小区0和小区1,在用于指示HARQ-ACK的消息中,如果两组HARQ-ACK复用资源,则这两个小区对应用于指示同一个上行时隙的多个DCI,其中,浅色填充的DCI表示低优先级DCI,深色填充的DCI表示高优先级DCI,图中所示的时隙0、时隙1、时隙2、时隙3和时隙4所对应的DCI均用于指示同一个待传输时隙(即待HARQ-ACK传输的时隙),即高优先级HARQ-ACK和低优先级HARQ-ACK复用同一个时隙的资源,其中,可以根据最后一个高优先级DCI(时隙4中的高优先级DCI)中的至少部分字段来确定指定低优先级DCI的total DAI,以便于确定低优先级的HARQ-ACK的码本并以此进行译码。这样,即便指定低优先级DCI漏检,也可以根据最后一个高优先级DCI中的至少部分字段来协助确定指定低优先级的DCI的total DAI。与低优先级DCI相比,高优先级DCI往往具有更高的可靠性,不容易发生漏检,以此,提高了指定低优先级的DCI的total DAI的准确性。
本申请实施例中的HARQ-ACK传输方法,通过最后一个高优先级DCI中的至少部分字段来协助指示指定低优先级DCI的total DAI,从而降低了由于指定低优先级DCI的漏检而导致的译码错误的发生概率,即可以在不同优先级的HARQ-ACK的资源发生重叠时,提高复用的HARQ-ACK的传输性能。
在一种可能的实施方式中,其中,上述指定低优先级DCI为不超过最后一个高优先级DCI的时隙slot的最后一个低优先级DCI。
具体地,用于指示同一个上行时隙的DCI包括多个高优先级DCI和多个低优先级DCI,其中,UE获取最后一个高优先级DCI,根据其中的字段来指示不超过该最后一个高优先级DCI的时隙的最后一个低优先级DCI所对应的total DAI。例如,如图2所示,对于多小区配置来说,每个DCI中的“/”之前的字段表示计数counter DAI,“/”之后的字段表示total DAI,最后一个高优先级DCI的“2/2”用于指示该高优先级DCI本身的counter DAI和total DAI,最后一个高优先级DCI的“3”用于指示不超过高优先级DCI的时隙slot的最后一个低优先级DCI(时隙4中的低优先级DCI) 的total DAI,这样,即便其中最后一个低优先级DCI“3/3”漏检,也可以通过最后一个高优先级DCI“2/2,3”中的“3”来指示指定低优先级DCI的total DAI,终端译码DCI之后,便可以分别生成高优先级的码本和低优先级的码本,并进行联合或者分别编码,在DCI指示的PUCCH资源上传输不同优先级的HARQ-ACK,即实现了不同优先级的UCI复用在PUCCH上。例如,如图3所示,当最后一个低优先级DCI(时隙3中的“4/4”)漏检时,通过最后一个高优先级DCI(时隙4中的“2/2,4”中“4”)来指示指定低优先级DCI的total DAI,其中,“4”为低优先级DCI的total DAI,“2/2”为高优先级DCI本身的DAI,终端译码DCI之后,便可以分别生成高优先级的码本和低优先级的码本,并进行联合或者分别编码,在DCI指示的PUCCH资源上传输不同优先级的HARQ-ACK,即实现了不同优先级的UCI复用在PUCCH上。
在一种可能的实施方式中,高优先级的码本和低优先级的码本均为动态码本;最后一个高优先级DCI包括用于指示最后一个高优先级DCI的DAI的字段以及上述至少部分字段。例如,图2中最后一个高优先级DCI的字段“2/2”用于指示该高优先级DCI本身的DAI,而“3”为额外引入的用于指示指定低优先级DCI的total DAI的2比特字段,在后续步骤102中,根据最后一个高优先级DCI的total DAI的值2来确定码本大小并以此生成高优先级的码本,根据指定低优先级DCI的total DAI的值3来确定码本大小并以此生成低优先级的码本。例如,图3中最后一个高优先级DCI的字段“2/2”用于指示该高优先级DCI本身的DAI,而“4”为额外引入的用于指示指定低优先级DCI的total DAI的2比特字段,在后续步骤102中,根据最后一个高优先级DCI的total DAI的值2来确定码本大小并以此生成高优先级的码本,根据指定低优先级DCI的total DAI的值4来确定码本大小并以此生成低优先级的码本。
在一种可能的实施方式中,低优先级的码本为动态码本,高优先级的码本为半静态码本;上述最后一个高优先级DCI的某个字段用于指示指定低优先级DCI的total DAI。对于半静态码本,无需根据total DAI来确定码本大小,因此,可以直接借用最后一个高优先级DCI中的字段来指示指定低优先级DCI的total DAI,这样,无需在DCI中引入额外的字段。
在一种可能的实施方式中,如图2和图3所示,最后一个高优先级DCI和指定低优先级DCI均用于调度物理层上行控制信道PUCCH;上述步骤103、根据低优先级的码本和高优先级的码本对低优先级HARQ-ACK和高优先级HARQ-ACK进行编码的过程为:根据低优先级的码本和高优先级的码本对低优先级HARQ-ACK和高优先级HARQ-ACK进行联合编码或独立编码;步骤104、传输编码后的低优先级HARQ-ACK和高优先级HARQ-ACK的过程为:在PUCCH上传输编码后的低优先级HARQ-ACK和高优先级HARQ-ACK。
具体地,例如,如图2和图3所示,当高优先级和低优先级的业务都配置为动态码本,则可以通过最后一个高优先级DCI来指示截止当前时隙(最后一个高优先级DCI对应的时隙)的最后一个低优先级DCI的total DAI,此时,需要在最后一个高优先级DCI中额外引入2比特的字段来指示,当UE译码最后一个高优先级DCI 后,便可以知道低优先级的码本对应的大小,此时,UE按照比特大小生成高优先级码本和低优先级码本,并且进行联合或独立编码,然后在DCI指示的时隙上进行PUCCH传输。又例如,当低优先级业务配置为动态码本,高优先级业务配置为半静态码本,则也可以通过最后一个高优先级DCI来指示截止当前时隙(最后一个高优先级DCI对应的时隙)的最后一个低优先级DCI的total DAI,此时,可在对应的最后一个高优先级DCI中额外引入2比特的字段来指示指定低优先级DCI的total DAI,也可以借用最后一个高优先级DCI本身的字段来指示指定低优先级DCI的total DAI,当UE译码最后一个高优先级DCI后,便可以知道低优先级的码本对应的大小,此时,UE按照比特大小生成高优先级码本和低优先级码本,并且进行联合或独立编码,然后在DCI指示的时隙上进行PUCCH传输。
在一种可能的实施方式中,用于指示同一个上行时隙slot的多个下行控制信息DCI包括用于调度PUCCH的DCI以及用于调度物理层上行共享信道(Physical Uplink Shared Channel,PUSCH)的DCI;最后一个高优先级DCI用于调度PUSCH,指定低优先级DCI均用于调度PUCCH;上述步骤103、根据低优先级的码本和高优先级的码本对低优先级HARQ-ACK和高优先级HARQ-ACK进行编码的过程为:根据低优先级的码本和高优先级的码本对低优先级HARQ-ACK和高优先级HARQ-ACK进行独立编码;上述步骤104、传输编码后的低优先级HARQ-ACK和高优先级HARQ-ACK的过程为:在PUSCH上传输编码后的低优先级HARQ-ACK和高优先级HARQ-ACK。
具体地,例如,当高优先级和低优先级的业务都配置为动态码本,且复用后的UCI在PUSCH上传输时,可通过调度PUSCH的上行DCI,即用于指示同一个时隙的多个DCI中的最后一个高优先级DCI,通过该DCI来指示截止当前时隙(最后一个高优先级DCI对应的时隙)的最后一个低优先级DCI的total DAI,此时,需要在最后一个高优先级DCI中额外引入2比特的字段来指示,此时,UE译码完调度PUSCH的上行DCI后,便可以知道所指示的低优先级码本对应的总比特大小,UE按照比特大小分别生成高优先级和低优先级的码本,并且进行分别独立编码,然后在PUSCH上复用传输。如图4所示,最后一个高优先级DCI用于调度PUSCH,其他的DCI用于调度PUCCH,当最后一个低优先级DCI(时隙4上的DCI“3/3”)漏检时,通过同一个时隙上的上行DCI指示指定低优先级DCI的total DAI为3,该上行DCI即为最后一个高优先级DCI,即上行DCI会指示最后一个高优先级DCI的total DAI为2,UE编译DCI之后,便可以分别生成高优先级的码本和低优先级的码本,并进行分别对高优先级HARQ-ACK和低优先级HARQ-ACK编码,在PUSCH上传输编码后的高优先级HARQ-ACK和低优先级HARQ-ACK,即使不同优先级UCI复用在PUSCH上。
以上以配置两个小区为例对HARQ-ACK传输方法进行说明,但是本申请实施例对于小区配置的数量不作限定,例如,如图5所示,对于单小区配置来说,DCI仅用于指示total DAI,可以仅在一个小区对应的用于指示同一个上行时隙的多个DCI中,获取最后一个高优先级DCI,其中字段“2”用于指示指定低优先级DCI(最后一个低优先级DCI)的total DAI,其中字段“1”用于指示最后一个高优先级DCI本 身的total DAI,后续生成译码本、编码以及HARQ-ACK的传输过程与上述实施例中的过程类似,在此不再赘述,这里仅用于说明本申请实施例的HARQ-ACK传输方法可以适用于单小区配置,而不限于两个小区配置。又例如,如图6所示,对于三个小区的配置来说,在小区0、小区1和小区3三个校区对应的用于指示同一个上行时隙的多个DCI中,获取最后一个高优先级DCI,其中字段“6”用于指示指定低优先级DCI(最后一个低优先级DCI)的total DAI,其中字段“5/5”用于指示该高优先级DCI本身的counter DAI和total DAI,后续生成译码本、编码以及HARQ-ACK的传输过程与上述实施例中的过程类似,在此不再赘述,这里仅用于说明本申请实施例的HARQ-ACK传输方法可以适用于三个小区以及三个小区以上的配置,而不限于两个小区配置。
