本公开实施例中, 下行传输集合可选为 PDSCH 集合, 下行传输分组可 选为 PDSCH 分组。 需说明的是, 下述对本公开的说明中, 一些实施例是以 PDSCH集合和 /或 PDSCH分组为例进行的说明, 但不以此为限。
请参见图 1, 图 1 是本公开实施例提供的一种信息传输方法的流程图, 该方法应用于终端, 如图 1所示, 该方法包括如下步骤:
步骤 101 : 接收 DCI。
本实施例中, 此步骤中接收到的 DCI可以理解为一个 DCI集合, 该 DCI 集合中可以包括单个 DCI或者多个 DCI。
步骤 102 : 确定待传输 HARQ-ACK信息的目标比特序列。
其中, 所述待传输 HARQ-ACK 信息中包括第一信息, 所述第一信息为 所述 DCI触发的之前未成功反馈的 HARQ-ACK信息。 进一步的, 所述待传 输 HARQ-ACK信息中还可包括第二信息, 所述第二信息为所述 DCI调度的 下行传输的 HARQ-ACK信息, 即新调度的下行传输的 HARQ-ACK信息, 该 下行传输可选为 PDSCH传输,和 /或半持续调度 ( Semi-Persistent Scheduling, SPS) PDSCH释放指示过程。
可理解的, 对于接收到多个 DCI的情况, 可以在部分 DCI中包括触发信 息,该触发信息用于触发在触发之前未成功反馈的 HARQ-ACK信息的传输, 在部分 DCI中包括调度信息, 该调度信息用于调度新的下行传输。
一种实施方式中, 单一 DCI中可同时包括触发信息和调度信息, 该触发 信息用于触发在触发之前未成功反馈的 HARQ-ACK 信息的传输, 该调度信 息用于调度新的下行传输。
步骤 103 : 利用所述目标比特序列, 对所述待传输 HARQ-ACK信息进行 传输。
本公开实施例的信息传输方法, 可以在网络设备触发或请求终端上报之 前未成功反馈的 HARQ-ACK信息时,使得终端有效对待传输 HARQ-ACK信 息进行传输, 从而保证反馈效果。
本公开实施例中, 可选的, 为了确定待传输 HARQ-ACK 信息的目标比 特序列, 可以根据待传输 HARQ-ACK 信息对应的下行传输的下行分配索引 ( Downlink Assignment Index, DAI) 编号, 确定对应的目标比特序列。 比如 基于 NR Rel-15的动态码本 (Type-2) 机制, 扩展 DAI的计数范围, 将所有 需要在相同的 PUCCH资源上反馈的 HARQ-ACK信息对应的下行传输都纳入 DAI计数范围, 该下行传输可选为 PDSCH传输, 和 /或 SPS PDSCH释放指示 过程。
可选的, 上述步骤 102可包括:
确定待传输 HARQ-ACK信息对应的下行传输的 DAI编号; 其中, 所述 待传输 HARQ-ACK 信息对应的下行传输中的每个下行传输, 分别具有一个 DAI编号;
根据所述待传输 HARQ-ACK信息对应的下行传输的 DAI编号, 确定所 述待传输 HARQ-ACK信息的目标比特序列。
需说明的是, 此处根据 DAI编号确定目标比特序列的方式可采用相关技 术中的方式, 比如 NR Rel-15中的方式, 本公开实施例不对此进行限制。
本实施例中, 对于显式请求或触发之前未成功反馈的 HARQ-ACK 信息 的方案, 网络设备在调度某个 PDSCH传输时, 可确定该 PDSCH传输对应的 PDSCH分组, 即采用动态的 PDSCH分组方式, 每个 PDSCH分组对应独特 的索引或编号, 并对应一系列 (单个或多个) 调度的 PDSCH 传输, 可能还 涉及单个 SPS PDSCH释放指示, 而一个或多个 PDSCH分组可对应于一个 PDSCH集合。 该 PDSCH集合中的下行传输可以理解为单次显式请求或触发 对应的所有 PDSCH传输及 SPS PDSCH释放指示。
当扩展 DAI的计数范围之后, 可将所有需要在相同的 PUCCH资源上反 馈 HARQ-ACK 信息的下行传输 (包括新调度的, 以及后续触发的) 纳入单 一的 DAI编号范围, 即此 DAI编号范围在取模操作之前, 从 DAI最小值(可 选为 1) 开始编号, 相邻的 DAI编号连续, 直至对所有需要在相同 PUCCH 资源上反馈 HARQ-ACK信息的下行传输都编号完毕。
基于上述内容, 在确定各个下行传输在取模操作之前的 DAI编号时, 主 要需要考虑各个 PDSCH分组, 或者某个 PDSCH分组中的某个下行传输在单 一的 DAI编号范围内的位置, 并基于确定的位置, 确定各个 PDSCH分组中 的各个下行传输对应的 DAI编号在取模操作之前的取值。 其中, 此在取模操 作之前的 DAI编号在网络设备侧和终端侧间需保证理解的一致, 并在需要通 过信令在两侧之间通知 (主要是由网络设备通过 DCI通知终端) 时, 对相应 的 DAI编号执行取模操作, 并通过 DCI字段对相应取模的结果进行指示。 一种实施方式中, 所述待传输 HARQ-ACK 信息在相同的上行资源上传 输时, 所述待传输 HARQ-ACK信息对应的下行传输的各个 DAI编号在取模 操作之前是相互连续, 且从最小 DAI编号开始顺序递增的。
可选的, 上述待传输 HARQ-ACK信息对应的下行传输的 DAI编号可以 是以下任意一项:
( 1) 按照第一信息的触发时刻的先后顺序确定的
其中, 对于显式触发对应 HARQ-ACK信息上报的 PDSCH分组, 可以由 触发信令的传输时刻 (即触发时刻, 比如采用最后一次触发此 PDSCH 分组 的触发信令的传输时刻)确定该 PDSCH分组对应的 DAI编号范围在整个 DAI 编号范围内的相对位置。 若显式触发对应 HARQ-ACK 信息上报的下行传输 (PDSCH传输和 /或 SPS PDSCH释放指示过程), 则可以由触发信令的传输 时刻 (即触发时刻)确定该下行传输对应的 DAI编号在整个 DAI编号范围内 的相对位置。
当单个触发信令触发多个 PDSCH分组时,可以按照以下任意一种方式, 确定该多个 PDSCH分组的先后顺序:
方式一: 触发信令中指示多个 PDSCH分组时的先后顺序;
方式二: PDSCH分组的编号从小到大的顺序。
另外, 对于某个 PDSCH 分组, 如果被多次触发, 则以最后一次触发的 时刻为准。
(2) 按照第一信息对应的下行传输的调度时刻的先后顺序确定的 此情况下, 仅考虑相应下行传输的调度时刻, 不考虑后续再触发
HARQ-ACK 信息上报时的触发时刻。 即, 如果调度的各个下行传输对应的 HARQ-ACK信息在同一个 PUCCH资源中反馈, 则不管这些下行传输对应的 HARQ-ACK信息是否由在调度之后的后续显式信令触发,都基于调度各个下 行传输的 (原始) 时刻从前往后确定此下行传输在整个 DAI编号范围内的相 对位置。 当单个调度时刻调度了多个下行传输时, 可以基于这多个下行传输 在调度时确定的 DAI值在取模操作之前的取值从小到大排列来确定它们的先 后顺序。 (3) 按照下行传输分组的编号的从小到大的顺序确定的
其中, 所述第一信息对应于至少一个第一下行传输分组, 每个第一下行 传输分组分别具有一个编号; 每个第一下行传输分组中的下行传输的 DAI编 号的先后顺序是基于调度顺序确定, 相邻编号的下行传输分组对应的 DAI编 号之间在取模操作之前是相互连续的。
假设基于下行传输分组比如 PDSCH 分组, 来组织各个下行传输, 则针 对每个下行传输可在调度信令中指示其所属的 PDSCH 分组, 或者通过一些 预定义的规则确定其所属的 PDSCH分组。每个 PDSCH分组对应一个编号或 索引。 在确定每个 PDSCH分组中的各个下行传输在整个 DAI编号范围内的 相对位置时,可首先基于 PDSCH分组编号从小到大的顺序,确定各个 PDSCH 分组在整个 DAI编号范围内的相对位置, 然后基于每个 PDSCH分组内各个 下行传输在调度时指示的 DAI顺序, (比如基于取模操作之前的 DAI值), 确 定各个下行传输在对应 PDSCH分组对应的 DAI编号子范围内的相对位置, 即确定出每个 PDSCH分组中的各个下行传输在整个 DAI编号范围内的相对 位置。
可选的, 在待传输 HARQ-ACK 信息中既包括第一信息, 又包括第二信 息的情况下, 上述待传输 HARQ-ACK信息对应的下行传输的 DAI编号可以 是以下任意一项:
(1)按照第一信息的触发时刻和第二信息对应的下行传输的调度时刻的 先后顺序确定的;
其中, 对于显式触发对应 HARQ-ACK信息上报的 PDSCH分组, 可以由 触发信令的传输时刻 (即触发时刻, 比如采用最后一次触发此 PDSCH 分组 的触发信令的传输时刻)确定该 PDSCH分组对应的 DAI编号范围在整个 DAI 编号范围内的相对位置。 对于显式触发对应 HARQ-ACK 信息上报的下行传 输 (PDSCH传输和 /或 SPS PDSCH释放指示过程), 可以由触发信令的传输 时刻 (即触发时刻)确定该下行传输对应的 DAI编号在整个 DAI编号范围内 的相对位置。 同时, 对于新调度的下行传输 (PDSCH传输和 /或 SPS PDSCH 释放指示过程), 由调度时刻确定该下行传输对应的 DAI编号在整个 DAI编 号范围内的相对位置。 当单个 DCI中同时包含触发信息和调度信息时, 可首 先对实际由此触发信息触发的各个 PDSCH 分组 (即在此 DCI 之后, 对应 HARQ-ACK 信息上报之前, 没有其它 DCI 再使用触发信息显式触发此 PDSCH分组), 基于触发时刻 (即当前 DCI的传输时刻) 采用前述当单个触 发信令触发多个 PDSCH分组时确定该多个 PDSCH分组的先后顺序的某种方 式, 确定该 PDSCH分组对应的 DAI编号范围在整个 DAI编号范围内的相对 位置, 然后对新调度的下行传输(包括 PDSCH传输和 /或 SPS PDSCH释放指 示过程, 尚未涉及显式触发操作), 由调度时刻 (即当前 DCI 的传输时刻) 确定该下行传输对应的 DAI编号在整个 DAI编号范围内的相对位置;即先考 虑此 DCI中的触发信息, 再考虑此 DCI中的调度信息。
具体实现时, 网络设备比如 gNB可将每个触发信息对应的 PDSCH集合 (涉及 1 个或多个 PDSCH分组, 此时可将在此触发信息之后的触发信息中 指示的 PDSCH分组排除在外, 仅考虑剩余的 0个、 1个或多个 PDSCH分组 对应的各个下行传输, 以构成此 PDSCH 集合) 中的各个下行传输都对应独 立且连续的 DAI 编号, 这些编号与在触发信息之前或之后 (比如在同一个 DCI 中既包括触发信息, 又调度了新的下行传输的情况) 调度的新下行传输 对应的 DAI编号连续。 在相同 PUCCH资源上传输的 HARQ-ACK信息对应 的各个下行传输的 DAI编号在取模操作之前可相互连续,且从最小 DAI编号 (比如可选为 1) 开始顺序递增, 这样, 终端可以基于各个 DAI编号对应的 PDSCH传输的 HARQ-ACK或 SPS PDSCH释放指示的接收情况确定反馈比 特序列 (即 HARQ-ACK Codebook) o
例如, 参见图 2所示, 若 gNB在时隙 1 (Slotl) 利用 DCI1 (包括触发 信息 1)触发 PDSCH集合 1对应的 HARQ-ACK信息在 Slot7上报,该 PDSCH 集合 1 中的 PDSCH传输的 DAI编号范围为 DAITi,start^DAITi,End,对应的 DAI 编号数目为 DAIT1,Num ; 在 Slot2利用常规的 DCI2调度了 PDSCH1传输, 该 PDSCH1传输对应的 HARQ-ACK信息在 Slot7上报,该 PDSCH1传输的 DAI 编号为 DAIT1,End+l ; 在 Slot3利用 DCI3 (包括触发信息 2)触发 PDSCH集合 3对应的 HARQ-ACK信息在 Slot7上报,该 PDSCH集合 3中的 PDSCH传输 的 DAI编号范围为 DAlT2,Start DAlT2,End, 该 DAIT2, Start等于 DAIll,End+2 , 对应 的 DAI编号数目为 DAIT2,Num, 以及调度了 PDSCH2传输, 该 PDSCH2传输 对应的 HARQ-ACK 信息在 Slot7 上报, 该 PDSCH2 传输的 DAI 编号为 DAIT2,End+l ; 在 Slot4利用常规的 DCI4调度了 PDSCH3传输, 该 PDSCH3传 输对应的 HARQ-ACK信息在 Slot7 上报, 该 PDSCH3 传输的 DAI编号为 DAIT2,End+4, 则: 在 Slot7 中上报的 HARQ-ACK信息对应的 PDSCH传输的 DAI 编号范围为 DAIll, Start ^ DAIT2,End+2 , 对应的 DAI 编号数 目 为 DAITi,Num+DAlT2,Numo 其中, 上述 PDSCH1 传输、 PDSCH2传输和 PDSCH3 传输可以属于同一个 PDSCH分组, 可以在对应 DCI的调度信息中指示。
(2)按照第一信息和第二信息对应的下行传输的调度时刻的先后顺序确 定的
此情况下, 仅考虑相应下行传输的调度时刻, 不考虑后续再触发 HARQ-ACK 信息上报时的触发时刻。 即, 如果调度的各个下行传输对应的 HARQ-ACK信息在同一个 PUCCH资源中反馈, 则不管这些下行传输对应的 HARQ-ACK信息是否由在调度之后的后续显式信令触发,都基于调度各个下 行传输的 (原始) 时刻从前往后确定此下行传输在整个 DAI编号范围内的相 对位置。
(3 ) 按照下行传输分组的编号的从小到大的顺序确定的
其中, 所述第一信息对应于至少一个第一下行传输分组, 每个第一下行 传输分组分别具有一个编号, 每个第一下行传输分组中的下行传输的 DAI编 号的先后顺序是基于调度顺序确定; 所述第二信息对应于至少一个第二下行 传输分组, 每个第二下行传输分组分别具有一个编号; 每个第二下行传输分 组中的下行传输的 DAI编号的先后顺序是基于调度顺序确定; 相邻编号的下 行传输分组对应的 DAI编号之间在取模操作之前是相互连续的。
可理解的, 此方式中相邻编号的下行传输分组可以是相邻编号的两个第 一下行传输分组, 也可以是相邻编号的两个第二下行传输分组, 也可以是相 邻编号的第一下行传输分组和第二下行传输分组。
一种实施方式中, 第二下行传输分组可以不按照分组编号从小到大的顺 序和第一下行传输分组统一处理,而是单独额外处理。具体的处理过程可为: 首先按照下行传输分组的编号的从小到大的顺序确定所有涉及到的第一下行 传输分组的 DAI编号, 然后将涉及的第二下行传输分组内各下行传输的 DAI 编号放置在最后面, 而当涉及的第二下行传输分组有多个时, 也可按照第二 下行传输分组的编号从小到大的顺序处理所有涉及到的第二下行传输分组的 DAI编号。
可选的, 在待传输 HARQ-ACK 信息中包括第二信息, 且所述待传输 HARQ-ACK信息对应的下行传输的 DAI编号是, 按照下行传输分组的编号 的从小到大的顺序确定时, 所述至少一个第二下行传输分组对应的 DAI编号 位于所有 DAI 编号的最后面 (即最尾部, 取模操作前取值最大的子区间)。 对于每个第二下行传输分组内的各个下行传输之间的相对位置, 可基于调度 时刻, 或者调度时指示的 DAI顺序 (比如取模操作之前的 DAI值) 确定。
本公开实施例中, 网络设备基于调度情况进行 DAI计数时, 可以尽量避 免由于终端对于某些 DCI的漏检, 导致两侧对于 HARQ-ACK码本包含的比 特数 (HARQ-ACK Codebook Size), 以及各比特对应的下行传输的理解不一 致。 为了进一步增强鲁棒性, 网络设备还可以在触发信息中进一步指示其对 应的 PDSCH集合或对应的各个 PDSCH分组占用的 DAI编号数目。 另外, 为了确保终端发生 DCI漏检时, 网络设备侧和终端侧对触发信息对应的 DAI 编号范围有一致的理解, 还可以在触发信息中进一步指示相应的起始 DAI编 号和 /或结束 DAI编号。
可选的, 所述第一信息对应于至少一个第一下行传输集合, 每个第一下 行传输集合分别对应于至少一个第一下行传输分组, 每个第一下行传输集合 分别对应于一次触发过程; 所述 DCI中包括至少一个触发信息, 每个触发信 息是针对一次触发过程发送的, 每个触发信息中包括第一指示信息, 所述第 一指示信息用于指示以下任意一项:
对应的第一下行传输集合占用的 DAI编号数目;
对应的各个第一下行传输分组占用的 DAI编号数目。
进一步的, 所述第一指示信息还用于指示以下任意一项:
对应的第一下行传输集合的起始 DAI编号;
对应的各个第一下行传输分组的起始 DAI编号;
对应的第一下行传输集合的结束 DAI编号;
对应的各个第一下行传输分组的结束 DAI编号。 本公开实施例中, 当调度一个或多个下行传输 (包括 PDSCH传输和 /或 SPS PDSCH释放指示) 在相同的单个 PUCCH资源 (相同的时域位置) 上反 馈对应的 HARQ-ACK信息时,这些 HARQ-ACK信息的反馈比特序列可以作 为单个 HARQ-ACK码本。此外, 网络设备也可以触发终端在单个 PUCCH资 源上传输之前基于上述调度时序应在过去的某个 PUCCH资源上反馈但实际 并未成功传输的一个或多个 HARQ-ACK码本, 或者之前已触发但实际并未 成功传输的一个或多个 HARQ-ACK码本。 此时终端需要在网络设备指示的 单个 PUCCH资源上传输一个或多个上述 HARQ-ACK码本,每个 HARQ-ACK 码本既可能是由调度时序确定的 (一般情况下单个 PUCCH资源上只能传输 单个这样的码本), 也可能是被触发的。 如果将上述单个 PUCCH资源上传输 的 HARQ-ACK比特序列作为合并后的单个 HARQ-ACK码本,则在合并前的 每个 HARQ-ACK码本可作为参与合并的 HARQ-ACK子码本。 在构造某个 HARQ-ACK子码本时, 可以采用 NR Rel-15规定的半静态码本 (Type-1) 或 动态码本 (Type-2)。
对于在相同 PUCCH资源上反馈的多个 HARQ-ACK子码本,一种目标比 特序列的实现方式为:将各个 HARQ-ACK子码本对应的比特序列顺序级联, 形成统一的反馈比特序列。
可选的, 当所述第一信息对应于至少一个第一下行传输集合, 每个第一 下行传输集合分别对应于一次触发过程, 每个第一下行传输集合分别对应于 至少一个 HARQ-ACK子码本,每个 HARQ-ACK子码本分别具有一个索引值, 且各个 HARQ-ACK子码本的索引值互不相同时, 所述目标比特序列可以包 括以下任意一项:
按照索引值从小到大的顺序, 级联的各个索引值对应的 HARQ-ACK子 码本的比特序列; 其中, 对于多个 HARQ-ACK子码本的索引值, 可以是连 续的, 也可以是不连续的;
按照第一信息的触发时刻的先后顺序, 级联的各个 HARQ-ACK子码本 的比特序列; 可选地, 当单个触发时刻触发了多个 HARQ-ACK子码本时, 可按照索引值从小到大的顺序级联这些 HARQ-ACK子码本的比特序列。
可选的, 对于待传输 HARQ-ACK信息中既包括第一信息, 又包括第二 信息的情况, 当所述第一信息对应于至少一个第一下行传输集合, 每个第一 下行传输集合分别对应于一次触发过程, 每个第一下行传输集合分别对应于 至少一个 HARQ-ACK子码本, 所述第二信息对应于至少一个第二下行传输 集合 (其中, 该第二下行传输集合中可包括一个或多个调度的下行传输, 而 多个调度的下行传输可由多个包括调度信息的 DCI 来调度), 每个第二下行 传输集合分别对应于一个 HARQ-ACK子码本,每个 HARQ-ACK子码本分别 具有一个索引值, 且各个 HARQ-ACK子码本的索引值互不相同时, 所述目 标比特序列可以包括以下任意一项:
按照索引值从小到大的顺序, 级联的各个索引值对应的 HARQ-ACK子 码本的比特序列; 其中, 对于多个 HARQ-ACK子码本的索引值, 可以是连 续的, 也可以是不连续的;
按照第一信息的触发时刻和第二信息对应的下行传输的调度时刻的先后 顺序, 级联的各个 HARQ-ACK子码本的比特序列; 可选地, 当单个触发时 刻触发了多个 HARQ-ACK子码本时, 可按照索引值从小到大的顺序级联这 些 HARQ-ACK子码本的比特序列; 可选地, 当第二信息对应的某个第二下 行传输集合包含多个下行传输时, 可以采用调度时刻最靠后的下行传输的调 度时刻。
可理解的是, 此方案中, 对于单个下行传输集合 (即单个第一下行传输 集合, 或单个第二下行传输集合), 其中的下行传输对应的 HARQ-ACK信息 在相同上行资源上传输。 当采用动态码本时, 每个下行传输集合可以对应一 个或多个下行传输分组, 在每个下行传输分组内 DAI编号可以独立累计, 无 需形成统一的单个 DAI编号范围, 即 DAI编号 (取模操作之前) 可以仅在各 个下行传输分组对应的 DAI编号范围内生效及唯一。 可选地, 当采用动态码 本时, 第二下行传输集合与下行传输分组一一对应。
例如, 参见图 3所示, 若 gNB在 Slotl利用 DCI1 (包括触发信息) 触发 PDSCH集合 1对应的 HARQ-ACK信息在 Slot7上报,该 PDSCH集合 1对应 单个 HARQ-ACK子码本, 它的索引值为 1 ; 在 Slot3利用 DCI3 (包括触发信 息) 触发 PDSCH集合 3对应的 HARQ-ACK信息在 Slot7上报, 该 PDSCH 集合 3对应单个 HARQ-ACK子码本, 它的索引值为 3 ; 在 Slot2利用 DCI2 调度了归属于 PDSCH集合 2的 PDSCH1传输, 在 Slot3利用 DCI3调度了归 属于 PDSCH集合 2的 PDSCH2传输,在 Slot4利用 DCI4调度了归属于 PDSCH 集合 2的 PDSCH3传输, 该 PDSCH集合 2对应单个 HARQ-ACK子码本, 它的索引值为 2 ; 贝 : 在 Slot7中上报的 HARQ-ACK信息的目标比特序列包 括: 按照索引值从小到大的顺序, 级联的如下比特序列: PDSCH集合 1对应 的 HARQ-ACK子码本的比特序列、 PDSCH集合 2对应的 HARQ-ACK子码 本的比特序列, 和 PDSCH集合 3对应的 HARQ-ACK子码本的比特序列。
进一步的, 在待传输 HARQ-ACK 信息中包括第二信息, 即存在新调度 的下行传输对应的 HARQ-ACK 子码本时, 在级联得到目标比特序列时, 可 以显式地将此 HARQ-ACK子码本置于所有其它 HARQ-ACK子码本的最前面 或最后面, 即所述至少一个第二下行传输集合对应的 HARQ-ACK 子码本位 于目标比特序列的最前面或最后面。
可选的, 所述目标比特序列中可包括指示比特, 所述指示比特用于指示 所述目标比特序列中级联的 HARQ-ACK 子码本的索引值, 以增强灵活性和 鲁棒性。 比如具体实现时, 对于目标比特序列, 可在级联每个 HARQ-ACK 子码本对应的比特序列之前, 新增指示比特 (比特数目需保证能够指示所有 可能需要指示的索引值, 可参考触发 DCI 中的比特位数及取值设置), 以显 式指示对应 HARQ-ACK子码本的索引值。
本公开实施例中, 为了避免某些或某个索引值对应的 HARQ-ACK 子码 本在网络设备侧和终端侧存在不一致的理解 (例如当采用动态码本时, 如果 终端漏检最后一个时隙内的所有 DCI, 则可能会导致两侧对于码本的大小理 解不一致), 可以在针对各个 HARQ-ACK子码本对应的比特序列进行级联之 前,按照级联顺序分别给出各个 HARQ-ACK子码本的长度指示。进一步的, 还可以在指示各个 HARQ-ACK子码本的长度之前, 先指示对应 HARQ-ACK 子码本的索引值。
可选的, 所述方法还包括:
向网络设备发送第二指示信息;
其中, 所述第二指示信息用于按照所述目标比特序列的级联顺序, 分别 指示各个 HARQ-ACK子码本的长度。 这样, 借助第二指示信息, 可以避免某些或某个索引值对应的 HARQ-ACK子码本在网络设备侧和终端侧存在不一致的理解。
可选的, 所述方法还包括:
向网络设备发送第三指示信息;
其中, 所述第三指示信息用于按照所述目标比特序列的级联顺序, 分别 指示各个 HARQ-ACK子码本的索引值。
这样, 借助第三指示信息, 可以避免某些或某个索引值对应的 HARQ-ACK子码本在网络设备侧和终端侧存在不一致的理解。
具体实现时, 上述的第二指示信息和第三指示信息可以分开单独发送, 也可以合并为一个指示信息同时发送。
本公开实施例中, 当利用 HARQ-ACK子码本反馈 HARQ-ACK信息时, 一些 HARQ-ACK 子码本中的比特指示的信息可能已经过期, 可以由后续 HARQ-ACK子码本中指向相同 HARQ进程的比特来覆盖, 例如对于提前调 度重传的场景, 某个 HARQ进程对应的 HARQ-ACK比特可能会同时出现在 两个或多于两个的 HARQ-ACK子码本中,其中仅最近设置的 HARQ-ACK比 特 (对应最新的解码结果) 对于网络设备才有参考意义, 之前设置的 HARQ-ACK 比特已失效。 此外, 当 DCI存在漏检时, 由于终端可能并不知 道漏检的 DCI对应哪个 HARQ进程, 因此无法对 HARQ进程的冗余比特进 行准确判断, 即无法准确地全部识别出各个 HARQ-ACK 子码本之间的冗余 比特。
考虑到上述终端对冗余比特判断不准确的情况, 在对 HARQ-ACK 子码 本进行比特级联形成目标比特序列的基础上, 可以进一步优化目标比特序列 的长度, 控制实际传输的 HARQ-ACK比特序列的长度。
可选的, 当所述目标比特序列的比特数超过当前所有 HARQ进程的数目 的预设比例时, 上述步骤 103之前, 所述方法还包括:
确定实际传输的 HARQ-ACK比特序列;其中,该实际传输的 HARQ-ACK 比特序列的比特数小于或等于所述当前所有 HARQ进程的数目。
上述步骤 103 可包括: 利用所述实际传输的 HARQ-ACK比特序列, 对 所述当前所有 HARQ进程的 HARQ-ACK信息进行传输。 其中, 该当前所有 HARQ进程可以是协议预先约定的, 或者配置的。 该 预设比例可以是提前配置, 或者由协议约定的。
比如, 当终端判断针对单个载波需要反馈的比特数超过单个载波上的 HARQ进程数, 或者超过单个载波上的 HARQ进程数的某个比例 (可以提前 配置, 或者由协议约定) 时, 终端可以控制实际传输的 HARQ-ACK 比特序 列的长度, 直接反馈针对所有 HARQ进程的 HARQ-ACK信息。 其中, 该载 波上各 HARQ进程对应的反馈比特可以按照进程 ID采用位图 Bitmap的方式 排列;对于终端已检测到对应 DCI的 HARQ进程,终端可以使用占用此 HARQ 进程的最后一次 PDSCH传输对应的解码结果;对于终端没有检测到对应 DCI 的 HARQ 进程, 终端可以设置为否定应答 ( Negative Acknowledgement , NACK), 或者此 HARQ进程之前的传输(不在本次触发反馈范围内)对应的 解码结果。
