相关申请的交叉引用
本申请主张在2019年7月30日在中国提交的中国专利申请No.201910693476.0的优先权,其全部内容通过引用包含于此。
本公开涉及通信技术领域,特别是指一种混合自动重传码本的确定、指示方法、终端及网络设备。
新无线(New Radio,NR)***包括两种混合自动重传(Hybrid Automatic Repeat Request,HARQ)反馈码本:半静态码本(Type-1 HARQ codebook)和动态码本(Type-2 HARQ codebook)。
半静态码本的构建方式如下:
对于某个上行时隙或者子时隙(slot/sub-slot)承载的物理上行控制信道(Physical Uplink Control Channel,PUCCH),用户设备或者终端(User Equipment,UE)根据以下信息,决定为一系列物理下行共享信道(Physical Downlink Shared Channel,PDSCH)传输时机反馈HARQ-ACK:
1)一组时隙或者子时隙的时间值K1(a set of slot/sub-slot timing values K1);
2)高层通过物理下行共享信道-时间域资源分配列表(PDSCH-Time Domain Resource Allocation List)配置的TDRA表格;
3)半静态帧结构配置,例如:配置一个K1集合,以子时隙sub-slot为单位,K1={1,2,3,4,5,6,7,8},对于UL sub-slot n和UL sub-slot n+1包含的PUCCH,分别要反馈以下PDSCH(s)对应的HARQ-ACK:
Sub-slot n上的PUCCH:反馈UL sub-slot n-1~UL sub-slot n-8对应的PDSCH(s)的HARQ ACK;
Sub-slot n+1上的PUCCH:反馈UL sub-slot n~UL sub-slot n-7对应的 PDSCH(s)的HARQ-ACK;
且无论是否真的有PDSCH传输,只要有有效的传输机会,就会反馈HARQ-ACK;
若在同一个下行时隙,支持多于一个单播PDSCH接收,则为所述下行时隙,需要预留的HARQ-ACK比特数确定方式如下:
步骤1:遍历TDRA表格,找到结束符号最小的一行,预留1比特;
步骤3:对TDRA表格剩余的行执行步骤1,2。
如图1所示,根据Type-1 HARQ码本的生成方式,对于阴影的两行,只预留了一个HARQ-ACK比特,因此,对于被赋值为一个相同值
的候选PDSCH(candidate PDSCH receptions),UE不期待接收多余一个PDSCH,否则UE在构建HARQ-ACK码本时就会发生错乱。
同一终端复用多种业务时,不同业务共存于同一终端,例如终端将集成三遥业务、差动保护业务以及网络授时业务,网联无人机将集成控制信息以及音视频两种业务,但是不同业务对时延、可靠性、数据速率的需求却有很大差异。
因此将存在以下场景:基站在slot n symbol#0~13调度了增强型移动宽带(eMBB)业务的PDSCH,但是此时超可靠、低时延通信(URLLC)数据到达,为了保证URLLC数据的时延,在slot n symbol#2~3调度URLLC的PDSCH;
根据上述Type-1 HARQ码本的构建方式,对于所述eMBB和URLLC的PDSCH,只会预留一个比特用于传输HARQ-ACK,因此UE在构建HARQ码本时,将会产生错乱。

如图2所示,本公开的实施例提供一种混合自动重传码本的确定方法,应用于终端,所述方法包括:
步骤21,确定物理下行共享信道(PDSCH)时域资源分配表格,所述PDSCH时域资源分配表格包含至少一个PDSCH时域资源分配信息,所述PDSCH时域资源分配信息至少包括第一信息和第二信息,所述第一信息用于指示混合自动重传HARQ码本,所述第二信息用于指示PDSCH时域资源;可选地,根据基站通过高层信令配置的PDSCH时域资源分配列表确定PDSCH时域资源分配表格,或者,根据协议预先约定的缺省PDSCH时域资源分配表格确定所述PDSCH时域资源分配表格;
可选地,这里的PDSCH时域资源分配表格中的每一个PDSCH时域资源分配信息对应所述PDSCH时域资源分配表格的一个行索引。这里的第二信息用于指示PDSCH时域资源,包括时隙偏移(slot offset)、开始符号和长度指示以及PDSCH映射类型(PDSCH mapping type)。
步骤22,根据第一信息和第二信息,确定混合自动重传码本。
本公开的该实施例中,基站通过高层信令配置的PDSCH时域资源分配列表,或者,根据协议预先约定的缺省PDSCH时域资源分配表格确定所述PDSCH时域资源分配表格的实现如下:
基站(网络设备)通过高层信令配置的方式,指示PDSCH时域资源分配列表(PDSCH-Time Domain Resource Allocation List)配置的TDRA表格中的每一行对应的HARQ码本;
PDSCH时域资源分配列表可以在物理下行共享信道公共配置(PDSCH-Config Common)中配置,或者,在物理下行共享信道配置(PDSCH-Config)中配置,或者,协议预先约定,例如默认PDSCH时域资源分配(Default PDSCH time domain resource allocation A)即在PDSCH时域 资源分配中增加一个字段HARQ-codebook,指示TDRA表格中的当前行;
TDRA表格中的一行中,包括:行索引、PDSCH映射类型(mappingType)、K0,起始符号S(Starting Symbol),长度L(Length)以及相对应的HARQ码本,具体地,行索引、k0、映射类型、起始符号和长度对应的HARQ码本的配置结果举例如下:
通过确定物理下行共享信道PDSCH时域资源分配表格,所述PDSCH时域资源分配表格包含至少一个PDSCH时域资源分配信息,所述PDSCH时域资源分配信息至少包括第一信息和第二信息,所述第一信息用于指示混合自 动重传HARQ码本,所述第二信息用于指示PDSCH时域资源。从而避免UE构建HARQ码本时产生的错乱,提升Type-1 HARQ码本对UE多业务复用场景的适用性。
本公开的一可选实施例中,步骤22可以包括:
步骤221,根据第一信息和第二信息,确定待构建混合自动重传码本需要的所述PDSCH时域资源分配表格的行索引集合。
可选地,步骤221可以包括:将所述第一信息指示的HARQ码本与待构建的HARQ码本相同的,PDSCH时域资源分配信息对应的行索引集合,确定为所述待构建混合自动重传码本需要的PDSCH时域资源分配表格的行索引集合。
该步骤的实现方式中,初始化所述待构建混合自动重传码本需要的PDSCH时域资源分配表格的行索引集合R为空集,遍历所述PDSCH时域分配表格包含的每一PDSCH时域资源分配信息对应的行索引,对于任一行索引r:
a)若所述第一信息指示的HARQ码本与待构建的HARQ码本相同,则将所述行索引r加入到所述待构建混合自动重传码本需要的PDSCH时域资源分配表格的行索引集合R;
b)若所述第一信息指示的HARQ码本与待构建的HARQ码本不同,则判断行索引r+1,并继续执行a)和b)的步骤。
该可选的实施例中,对于每个HARQ码本,对应于所述待构建HARQ码本需要的PDSCH时域资源分配的行索引集合R中至少两行,终端在同一个下行时隙或者同一个下行子时隙不期待接收多于一个PDSCH,所述多于一个PDSCH对应的候选PDSCH接收机会索引相同。
本公开的另一可选实施例中,步骤22可以包括:
步骤222,将所述PDSCH时域资源分配表格中每一个PDSCH时域资源分配信息对应的行索引作为待构建HARQ码本需要的行索引集合R;
步骤223,对于集合R中的任一行索引r,如果第一信息指示的HARQ码本与待构建的HARQ码本不同,则将r从集合R中去除。
该步骤的实现方式中,遍历所述行索引集合R中的行索引,对于任一行 索引r:
a)若第一信息指示的HARQ码本与待构建的HARQ码本不同,则将r从集合R中去除;
b)若第一信息指示的HARQ码本与待构建的HARQ码本相同,则继续判断行索引r+1,并继续执行a)和b)步骤。
该另一可选的实施例中,对于每个HARQ码本,对应于所述待构建HARQ码本需要的PDSCH时域资源分配的行索引集合R中至少两行,终端在同一个下行时隙或者同一个下行子时隙不期待接收多于一个PDSCH,所述多于一个PDSCH对应的候选PDSCH接收机会索引相同。
例如,终端在构建半静态码本的时候,例如终端构建HARQ codebook 1时:
终端接收协议预定义或者通过高层信令配置的TDRA表格,以及HARQ码本指示信息;
根据接收到的TDRA表格以及HARQ码本指示信息,选择TDRA表格中的HARQ码本指示信息为“码本1”的配置/行,组成构建半静态码本构建需要遍历的TDRA表格“配置集合”或者“行集合”R,之后按照半静态码本构建步骤构建。
另一种实现方式中,UE通过接收基站发送的高层信令和/或物理层下行控制信息,确定承载第一HARQ码本的slot/sub-slot和/或PUCCH(物理上行控制信道)资源;
对于赋值为相同
值的,且根据基站发送的高层信令和/或调度所述PDSCHs的物理层下行控制信息,确定的承载第一HARQ码本的slot(时隙)/sub-slot(子时隙)和/或PUCCH资源相同的,候选PDSCH接收机会,UE在同一个slot/sub-slot不期待接收多于一个PDSCH;
如图3所示,基站在第二个DL slot调度了eMBB的PDSCH 1在symbol(符号)#0~13传输,随之URLLC(超可靠、低时延通信)数据到达,为了保证URLLC业务的时延,基站同样在第二个DL slot的symbol#2~3调度了URLLC的PDSCH 2。通过基站发送的高层信令和/或调度eMBB(增强移动宽带)PDSCH 1的物理层下行控制信息,确定第一HARQ码本为在最后一 个UL slot上的PUCCH传输的HARQ码本1;通过基站发送的高层信令和/或调度URLLC PDSCH 2的物理层下行控制信息,确定第一HARQ码本为在倒数第二个UL slot上的sub-slot 1上的PUCCH传输的HARQ码本2。UE不期待上述两个第一HARQ码本相同;
上述URLLC和eMBB业务只是一个举例,也可能是两种时延要求不同的URLLC业务,或者两种时延要求不同的eMBB业务。
所述两个第一HARQ码本用于承载PDSCHs的HARQ-ACK信息。这里,调度PDSCH的PDCCH会指示其HARQ-ACK所在的slot/PUCCH,该PUCCH承载HARQ码本,但是没有被调度PDSCH的PDCCH指示的slot/PUCCH承载的HARQ码本可能也需要承载该PDSCH的HARQ-ACK信息,这是由半静态码本的特性决定的。
本公开的上述实施例,通过高层信令以及物理层下行控制信息,将重叠的PDSCHs的HARQ-ACK信息指示到不同的HARQ码本上,避免UE构建HARQ码本时的错乱,提升Type-1 HARQ码本对intra-UE多业务复用场景的适用性。
本公开的实施例还提供一种混合自动重传码本的指示方法,应用于网络设备,所述方法包括:
向终端发送物理下行共享信道PDSCH时域资源分配列表,所述PDSCH时域资源分配列表用于终端根据所述PDSCH时域资源分配列表确定PDSCH时域资源分配表格,所述PDSCH时域资源分配表格包含至少一个PDSCH时域资源分配信息,所述PDSCH时域资源分配信息至少包括第一信息和第二信息,所述第一信息用于指示混合自动重传HARQ码本,所述第二信息用于指示PDSCH时域资源。
可选地,向终端发送物理下行共享信道PDSCH时域资源分配列表,包括:通过高层信令,向终端发送所述PDSCH时域资源分配列表。
本公开的上述实施例,通过高层信令以及物理层下行控制信息,将重叠的PDSCHs的HARQ-ACK信息指示到不同的HARQ码本上,避免UE构建HARQ码本时产生的错乱,提升Type-1 HARQ码本对UE多业务复用场景的适用性。
