为了更好地描述本申请实施例的原理和具体实施方式,以下对本申请实施例的相关技术内容进行描述。应理解,本申请实施例提供的方法包括以下内容中的至少部分内容。
在网络设备和终端设备的信息传输过程中,终端设备在接收物理下行共享信道(Physical Downlink Shared Channel,PDSCH)后发送PDSCH对应的HARQ应答信息(也称为HARQ-ACK信息或HARQ-ACK反馈信息)。HARQ-ACK信息用于表征PDSCH的译码是否正确。在一些实施例中,HARQ-ACK信息包括肯定应答ACK信息或否定应答NACK信息。
网络设备可以通过下行控制信息(Downlink Control Information,DCI)调度PDSCH传输,其中该DCI中包括物理上行控制信道(Physical Uplink Control Channel,PUCCH)资源的指示信息,该PUCCH资源可以用于发送该PDSCH对应的HARQ-ACK反馈信息。
HARQ-ACK信息反馈时的HARQ-ACK码本(codebook)的确定方法包括类型1 Type-1 HARQ-ACK码本(也称为semi-static HARQ-ACK codebook或半静态HARQ-ACK码本)确定、类型2 Type-2 HARQ-ACK码本(也称为dynamic HARQ-ACK codebook或动态码本)确定、增强的类型2 eType-2 HARQ-ACK码本(也称为enhanced dynamic HARQ-ACK codebook或增强的动态码本)以及类型3 Type-3 HARQ-ACK码本(也称为One Shot HARQ-ACK codebook或单次反馈码本)确定中的至少一种。
如果终端设备被配置eType-2 HARQ-ACK码本,网络设备在使用DCI格式1_1向终端设备调度PDSCH传输时,可以对调度的PDSCH进行分组,并通过显示信令指示PDSCH的分组信息,以使终端设备在接收到PDSCH后根据不同的分组进行对应的HARQ-ACK反馈。或者说,网络设备调度终端设备进行PDSCH接收的DCI中包括组标号(PDSCH group index)的指示信息和新反馈指示NFI(New feedback indicator)的指示信息。该方式下PDSCH最多可以被分为2个组例如为组0或组1。网络设备在触发终端设备进行HARQ-ACK反馈时可以触发一个组的反馈,也可以同时触发两个组的反馈。具体地,DCI信息中可以包括反馈请求组个数的信息域(Number of requested PDSCH group(s))。如果终端设备接收到网络设备发送的DCI信息,并且该DCI信息中的反馈请求组个数信息域为预设值例如设置为1,那么终端设备需要进行两个组的HARQ-ACK反馈。
如果终端设备被配置eType-2 HARQ-ACK码本,网络设备在使用DCI格式1_0向终端设备调度PDSCH传输时,由于DCI格式1_0的调度中不包括组标号和NFI指示,因此,DCI格式1_0的调度包括两种情况:
情况1:如果在上一次用于传输包括组0的HARQ-ACK反馈信息的PUCCH传输机会之后,且在下一次PUCCH传输机会之前,UE收到至少一个DCI格式1_0的调度,且UE收到指示组0的NFI信息的DCI,那么UE认为该至少一个DCI格式1_0的调度属于组0,该至少一个DCI格式1_0的调度对应的NFI信息根据该组0对应的NFI信息确定,其中,该下一次PUCCH传输机会是根据该至少一个DCI格式1_0确定的。
情况2:如果在上一次用于传输包括组0的HARQ-ACK反馈信息的PUCCH传输机会之后,且在下一次PUCCH传输机会之前,UE收到至少一个DCI格式1_0的调度,但UE没有收到指示组0的NFI信息的DCI,那么UE认为该至少一个DCI格式1_0的调度不属于任何组(或者说不属于组0也不属于组1),其中,该下一次PUCCH传输机会是根据该至少一个DCI格式1_0确定的。
在终端设备被配置了eType-2 HARQ-ACK码本反馈的情况下,终端设备通常还可以被配置Type-1 HARQ-ACK码本或Type-2 HARQ-ACK码本。或者,如果终端设备未被配置Type-1 HARQ-ACK码本且未被配置Type-2 HARQ-ACK码本,终端设备可以默认使用Type-1 HARQ-ACK码本。
对于上述情况1,在UE认为DCI格式1_0的调度属于组0的情况下,UE根据eType-2 HARQ-ACK码本生成待传输的HARQ-ACK码本,其中,该待传输的HARQ-ACK码本包括该至少一个DCI格式1_0 调度的PDSCH对应的HARQ-ACK信息。
对于上述情况2,在UE认为DCI格式1_0的调度不属于任何组的情况下,UE根据Type-1 HARQ-ACK码本或Type-2 HARQ-ACK码本生成待传输的HARQ-ACK码本,其中,该待传输的HARQ-ACK码本包括该至少一个DCI格式1_0调度的PDSCH对应的HARQ-ACK信息。
应理解,对于上述情况2,可能会出现网络设备和终端设备对DCI格式1_0的码本生成方式理解不一致的情况。例如,网络设备为终端设备发送了指示组0的NFI信息的DCI,但终端设备没有收到该指示组0的NFI信息的DCI,那么网络设备会认为该至少一个DCI格式1_0的调度属于组0,对应的码本生成方式为eType-2 HARQ-ACK码本,但终端设备会认为该至少一个DCI格式1_0的调度不属于任何组,对应的码本生成方式为Type-1 HARQ-ACK码本或Type-2 HARQ-ACK码本,从而导致网络设备和终端设备对该至少一个DCI格式1_0对应的HARQ-ACK反馈信息的码本生成方式出现理解不一致。
在终端设备被配置了eType-2 HARQ-ACK码本反馈的情况下,如果终端设备收到至少一个DCI格式1_0调度的不属于任何组的至少一个PDSCH,该至少一个PDSCH对应的第一HARQ-ACK信息被指示通过第一PUCCH反馈;另外该终端设备被第一DCI格式调度传输第一PUSCH,若该第一PUCCH与该第一PUSCH在时域上至少部分重叠,那么终端设备可以将该第一HARQ-ACK信息复用到该第一PUSCH上传输。其中,在第一DCI格式中包括上行下行分配指示(DAI,Downlink assignment index)域(例如第一DCI格式包括DCI格式0_1或DCI格式0_2)的情况下,终端设备可以根据该第一DCI格式中的上行DAI域,确定包括第一HARQ-ACK信息的第一HARQ-ACK码本的生成方式,从而可以解决上述网络设备和终端设备对该至少一个DCI格式1_0对应的HARQ-ACK反馈信息的码本生成方式的理解不一致的问题。

根据本申请的实施例,当终端设备收到DCI格式1_0调度的至少一个PDSCH,可能出现终端设备认为该至少一个PDSCH不属于任何一个组,但网络设备认为该至少一个PDSCH属于组0的情况。在这种情况下,当该至少一个PDSCH对应的HARQ-ACK信息通过DCI格式0_1调度的PUSCH进行反馈时,可以通过DCI格式0_1中的上行DAI指示信息来确定终端设备应生成的HARQ-ACK码本,从而避免终端设备和网络设备对HARQ-ACK码本的理解歧义。
在终端设备被配置了eType-2 HARQ-ACK码本反馈情况下,终端设备收到至少一个DCI格式1_0调度的不属于任何组的至少一个PDSCH,该至少一个PDSCH对应的第一HARQ-ACK信息(或者说,至少一个DCI格式1_0调度的PDSCH对应的HARQ-ACK反馈信息)被指示通过第一PUCCH反馈。如果该第一PUCCH与该终端设备被第一DCI格式调度的第一PUSCH在时域上至少部分重叠,那么终端设备可以将该第一HARQ-ACK信息复用到该第一PUSCH上传输。其中,可选地,第一DCI格式包括DCI格式0_1。
