Definitions

  • the present application relates to the field of wireless communication technologies, and in particular, to a hybrid automatic repeat request response method and device.
  • the HARQ mechanism is used to improve the efficiency of data transmission.
  • each cell has a HARQ entity, and the uplink and downlink are independent.
  • Each HARQ entity contains multiple parallel HARQ processes.
  • the terminal equipment UE instructs the physical layer to send the acknowledgement ACK or non-acknowledgement NACK information.
  • the ACK and NACK information are collectively referred to as hybrid automatic repeat request response information HARQ-ACK.
  • the whole of the HARQ-ACK information fed back by the UE on one HARQ feedback resource (PUCCH or PUSCH) is called a HARQ-ACK codebook.
  • Semi-Persistent Scheduling allows to periodically allocate PDSCH or PUSCH resources to a specific UE through one physical downlink control channel scheduling. That is, SPS scheduling has the characteristics of "once allocation, multiple use”. In addition, SPS scheduling can prevent the base station from sending scheduling information corresponding to the PDSCH to the UE when there is a downlink data requirement, which can reduce the downlink data transmission delay and meet the delay-sensitive service transmission requirements.
  • the data scheduled by the SPS supports HARQ transmission. For each PDSCH transmission scheduled according to the SPS, the UE sends the corresponding HARQ-ACK on the PUCCH resource corresponding to each PDSCH.
  • the NR system will support configuring multiple sets of SPS parameters for the UE to meet the service requirements of the TSN, and the parameters of multiple sets of SPS can be configured independently.
  • the NR system will support service types with a short configuration period for the UE. For example, the SPS support period is 1 slot length.
  • the UE feeds back the HARQ-ACK corresponding to the PDSCH in time slot n+k.
  • the value of k is determined by the "PDSCH-to-HARQ-timing-indicator" field in the PDCCH that activates the SPS, or determined by the higher layer signaling "dl-DataToUL-ACK". If the value of k is determined by "PDSCH-to-HARQ-timing-indicator" in the PDCCH, this field indicates that the value of k is one of multiple values configured by "dl-DataToUL-ACK". In any case, after the SPS is activated, the timing difference between the PDSCH of the SPS and the corresponding HARQ-ACK feedback is unified as "k".
  • the feedback of HARQ-ACK is based on the time unit, and the length of the time unit is preset.
  • the time slot length is 14 symbols.
  • the symbols in one slot may include three types: DL (downlink) symbols, UL (uplink) symbols, or F (Flexible) symbols.
  • the preset time unit is a slot or a subslot.
  • the frame structure configuration adopts the combination of semi-static RRC configuration and dynamic DCI configuration.
  • the base station configures the semi-static frame format of the UE through the RRC cell level and the UE-specific level. According to the semi-static configuration, the UE can determine whether the symbols included in each time unit are DL symbols, UL symbols, or F symbols.
  • Semi-statically configured DL symbols are used for DL transmission, UL symbols are used for UL transmission, and F symbols can be used for downlink transmission and uplink transmission.
  • the system can adjust the frame format configuration through the slot structure indication (Slot format indication, SFI).
  • SFI slot format indication
  • the time slot structure indication information is sent by the base station to the UE through DCI format 2_0.
  • the SFI can only change the semi-statically configured symbols of F to downlink symbols or uplink symbols, but cannot change the semi-statically configured DL symbols and UL symbols.
  • the flexible symbols indicated by the SFI cannot be used for semi-static upstream transmission.

In the case that the terminal device has actually obtained the PDSCH of the SPS correctly, the system efficiency is low, and the delay characteristic of the service is affected.
  • the period of the SPS configuration is very short, the HARQ-ACK feedback is very frequent, and the above-mentioned problem of canceling the HARQ-ACK feedback is particularly serious.
  • Delaying the canceled HARQ-ACK feedback to the PUCCH/PUSCH of other time units for transmission can solve the problem that the HARQ-ACK feedback corresponding to the PDSCH in the SPS configuration in the TDD system is canceled, which affects the system efficiency.

Description

一种混合自动重传请求应答方法和设备
本申请要求于2021年01月15日提交中国国家知识产权局、申请号为202110057874.0、发明名称为“一种混合自动重传请求应答方法和设备”的中国专利申请的优先权，该在先申请的全部内容通过引用结合在本申请中。
技术领域
本申请涉及无线通信技术领域，尤其涉及一种混合自动重传请求应答方法和设备。
背景技术
NR系统中使用混合自动重传请求应答HARQ机制提高数据传输的效率。在MAC层，每个小区都有一个HARQ实体，上下行独立。每个HARQ实体包含了多个并行的HARQ进程。终端设备UE根据解码结果，指示物理层发送确认ACK或者非确认NACK信息。ACK和NACK信息统称为混合自动重传请求应答信息HARQ-ACK。UE在一个HARQ反馈资源(PUCCH或PUSCH)上反馈的HARQ-ACK信息的整体称为HARQ-ACK码本。
半永久性调度SPS(Semi-Persistent Scheduling，或称半静态调度)，允许通过一次物理下行控制信道调度，将PDSCH或PUSCH的资源周期性地分配给某个特定UE。即SPS调度有“一次分配，多次使用”的特点。另外，SPS调度可以避免基站在有下行数据需求时再给UE发送PDSCH对应的调度信息，可降低下行数据传输的时延，满足时延敏感的业务传输需求。SPS调度的数据支持HARQ传输，针对根据SPS调度的每次PDSCH发送，UE均在与各PDSCH相应的PUCCH资源发送与之对应的HARQ-ACK。
对于时间敏感网络(TSN，Sensitive Networking)的业务有多个周期和紧急度优先的数据流。并且，在支持不定期突发的紧急业务的同时，TSN需要支持时延要求很低的业务。TSN网络下的业务可能并非符号、时隙、或者子帧的整数倍。一方面，NR系统将支持为UE配置多套SPS参数以满足TSN的业务需求，多套SPS的参数可以分别独立配置。NR系统将支持为UE配置周期很短的业务类型。例如，SPS支持周期为1个时隙长度。如果UE在时隙n接收SPS调度相关的PDSCH，UE在时隙n+k反馈和该PDSCH对应的 HARQ-ACK。k的取值由激活SPS的PDCCH中的“PDSCH-to-HARQ-timing-indicator”字段确定，或者由高层信令“dl-DataToUL-ACK”确定。如果k的取值由PDCCH中的“PDSCH-to-HARQ-timing-indicator”确定，该字段指示k的值为“dl-DataToUL-ACK”所配置的多个值中的一个。无论如何，激活SPS后，该SPS的PDSCH和与之对应的HARQ-ACK反馈之间的定时差统一为“k”。
HARQ-ACK的反馈基于时间单元，时间单元的长度是预设的。TDD系统中，正常CP情况下，时隙长度为14个符号。一个时隙内的符号可能包括三种类型：DL(下行)符号、UL(上行)符号、或者F(Flexible,灵活)符号。例如预设时间单元为时隙或者子时隙。帧结构配置采用半静态RRC配置和动态DCI配置结合的方式。基站通过RRC小区级和UE专用级配置为UE半静态的帧格式。根据该半静态配置，UE可确定各时间单元包括的符号各自为DL符号、UL符号、还是F符号。半静态配置的DL符号用于DL传输、UL符号用于UL传输、F符号可用于下行传输也可以用于上行传输。在配置半静态帧格式后，系统可以通过时隙结构指示信息(Slot format indication,SFI)调整帧格式配置。时隙结构指示信息通过DCI格式2_0由基站发送给UE。SFI只能将半静态配置为F的符号更改为下行符号或者上行符号，而不能更改半静态配置的DL符号和UL符号。SFI指示的灵活符号不能用作半静态的上行传输。
如果用于反馈SPS PDSCH的HARQ-ACK的PUCCH所在的时隙被配置为下行时隙，或者用于反馈SPS PDSCH的HARQ-ACK的PUCCH资源的至少一个符号被配置为下行符号或者灵活符号，该PUCCH将被取消。相应地，网络设备gNB在获取不到HARQ-ACK信息的情况下，只能对其所对应的SPS的PDSCH执行重传调度。在终端设备实际已经正确获取到该SPS的PDSCH的情况下，系统效率低下，且影响业务的时延特性。在SPS配置的周期很短的情况下，HARQ-ACK反馈非常频繁，上述HARQ-ACK反馈被取消的问题尤其严重。
将被取消的HARQ-ACK反馈延迟到其它时间单元的PUCCH/PUSCH上传输，可以解决TDD系统中SPS配置PDSCH对应的HARQ-ACK反馈被取消，影响系统效率的问题，为保证gNB可以正确接收被延迟发送的SPS PDSCH的HARQ-ACK，gNB和UE对于“其它”PUCCH/PUSCH的资源位置需要有相同 的确定结果。另外，取消的HARQ-ACK需要及时地反馈，以便不影响PDSCH调度的流程并保证SPS承载业务的服务性能需求。目前无现有技术解决gNB和UE如何确定“其它”PUCCH/PUSCH资源的问题，网络设备和终端设备无法就延迟传送的HARQ-ACK信息实现通信。

具体实施方式
以下结合附图，详细说明本申请各实施例提供的技术方案。
图1为TDD系统中SPS配置PDSCH对应的HARQ-ACK反馈被取消示意图。如图所示举例，SPS配置的周期为1个时隙，k＝3。时隙n、时隙n+1、时隙n+2发送的SPS PDSCH的HARQ-ACK分别在时隙n+3、时隙n+4和时隙n+5。由于时隙n+3中与SPS PDSCH对应的HARQ-ACK的PUCCH符号中部分被配置为下行符号，则时隙n发送的SPS PDSCH的HARQ-ACK将被迫取消，影响系统效率。
根据激活SPS的PDCCH确定SPS PDSCH和与之对应的HARQ-ACK反馈之间的定时差为“k”。对时间单元n的SPS PDSCH，根据该定时差确定其HARQ-ACK反馈的原定PUCCH位于基础时间单元n+k。由于基础PUCCH中至少一个符号是帧格式RRC配置的DL符号，或者是帧格式RRC配置的F符号但被SFI更改为的DL符号或F符号，原定PUCCH将被取消。那么确定一个目标信道来承载该SPS PDSCH的HARQ-ACK，将该HARQ-ACK称之为延迟HARQ-ACK。目标信道为PUCCH或者PUSCH。
为保证延迟HARQ-ACK可以正确从UE发送到gNB，需要确定一种方法，保证gNB和UE确定出一致的目标信道。UE在确定的目标信道发送延迟HARQ-ACK，gNB在确定的目标信道接收延迟HARQ-ACK。另外，延迟HARQ-ACK需要及时地反馈，以便gNB可以及时获取SPS PDSCH对应HARQ进程的传输ACK或NACK状态，在该HARQ进程调度数据重传或新数据传输，因此目标信道的确定需尽量不影响PDSCH调度的流程并保证SPS承载业务的服务性能需求。
gNB和UE确定“其它”PUCCH/PUSCH的资源的方法如下。
图2为本申请方法的实施例流程图。
第一方面，本申请提出一种混合自动重传请求应答方法，用于SPS配置的PDSCH的HARQ-ACK反馈因配置冲突被取消时，延迟发送所述HARQ-ACK，包含以下步骤101～104：
步骤101、生成指示信息，用于指示备选信道的范围，包含第一种备选信道所用的备选符号类型、第二种备选信道所包含的上行信道类型。
例如，本申请的方法中包含第一指示信息，用于指示：所述备选符号进一步包含半静态信息配置为灵活符号且时隙结构指示信息指示为上行的符号，或者，所述备选符号不包含半静态信息配置为灵活符号且时隙结构指示信息指示 为上行的符号。
再例如，本申请的方法中包含第二指示信息，用于指示：所述第二种备选信道包含动态调度的PUSCH，或者，所述第二种备选信道不包含动态调度的PUSCH，或者，所述第二种备选信道包含动态调度PDSCH的HARQ-ACK的PUCCH，或者，所述第二种备选信道不包含动态调度PDSCH的HARQ-ACK的PUCCH。
需要说明的是，所述第一指示信息、第二指示信息，可以是位于SPS的配置信息，还可以是位于激活PDCCH中的下行控制信息。
步骤102、确定延迟HARQ-ACK，延迟HARQ-ACK即被取消的HARQ-ACK。
SPS配置的PDSCH的HARQ-ACK反馈因配置冲突被取消。被取消的HARQ-ACK所在的原定PUCCH，位于一基础时间单元。对应于所述被取消的HARQ-ACK生成延迟HARQ-ACK。这些被取消的HARQ-ACK将在其它信道延迟发送，本申请中，将这些延迟发送的HARQ-ACK称为“延迟HARQ-ACK”。
所述配置冲突，是指用于反馈SPS PDSCH的HARQ-ACK的原定PUCCH所在的时隙被配置为下行时隙，或者用于反馈SPS PDSCH的HARQ-ACK的原定PUCCH资源的符号被配置为下行符号或者灵活符号，尤其是，所述配置冲突包含预设的用于反馈HARQ-ACK的原定PUCCH资源与TDD配置中的灵活符号或下行符号冲突。
被取消的HARQ-ACK所在的原定PUCCH，因配置冲突而未实施传送，在以下图3～5的各个实施例中，表示为“基础PUCCH”，所述基础PUCCH位于基础时间单元，所述基础PUCCH中包括被取消的HARQ-ACK，所述被取消的HARQ-ACK是针对目标SPS PDSCH的反馈信息，因所述基础PUCCH被丢弃，实际生成为延迟HARQ-ACK。
本申请的时间单元，可以为时隙、或者子时隙。时隙或者子时隙的时间长度是预设的。
步骤103、确定备选信道，所述备选信道包含第一种备选信道和第二种备选信道中的至少一种。
所述第一种备选信道是位于所述原定PUCCH结束时刻之后，在所述基础时间单元中或所述基础时间单元后续的时间单元中第一个备选符号开始依次 取连续的N 1个备选符号组成的信道，N 1是预设值，所述备选符号包含半静态信息指示的上行符号；
所述第二种备选信道是所述原定PUCCH结束时刻之后，在所述基础时间单元中或后续的时间单元中的以下至少一种信道：
配置为用于传输SPS的HARQ-ACK或者CSI的PUCCH，半静态调度的PUSCH。

图6为本申请的方法用于网络设备的实施例流程图。
本申请第一方面任意一项实施例所述方法，用于网络设备，包含以下步骤201～203：
步骤201、所述网络设备发送第一指示信息和/或第二指示信息。
关于第一指示信息
gNB可以通过第一指示信息指示确定发送该SPS PDSCH的取消HARQ-ACK的备选符号是否包括第一类符号。第一类符号指的是半静态信息配置为灵活符号且时隙结构指示信息指示为上行的符号。如果第一指示信息是第一状态，所述备选符号包括第一类符号；如果第一指示信息是第二状态，所述备选符号不包括第一类符号。第一指示信息可以在SPS的配置信息中发送给UE，可以在SPS的激活PDCCH中发送给UE。
根据现有技术，半静态帧格式配置中的UL符号和F符号都可以用作上行传输。如果不支持SFI更改帧格式配置，半静态配置的UL符号和F符号都是备选符号。如果支持SFI更改帧格式配置，半静态配置的F符号是否可以用于上行传输，取决于半静态F符号是否被SFI更改为DL符号、该上行传输是否半静态上行传输等。在SFI在UE侧没有被正确检测的情况下，gNB和UE对于哪些符号可以用作上行传输将有不同的确定结果。例如，半静态帧格式配置中时隙n的符号1～14的配置情况如下：
符号编号 1 2 3 4 5 6 7 8 9 10 11 12 13 14
符号方向 D D D D D D F F F F U U U U
在半静态帧格式配置的基础上，SFI将F符号的后两个更改为UL符号。如果UE没有正确检测该SFI，UE认为时隙n的符号中可用于上行传输的是符 号7～14。但是gNB认为时隙n的符号中可用于半静态上行传输的是符号9～14。如果某个目标信道的备选信道包括符号7、8。UE会认为该信道可以作为目标信道，但是gNB认为该信道不可以作为目标信道，将按照预设规则将其它备选信道确定为目标信道，导致取消HARQ-ACK不能被gNB正确接收。如果DL SPS配置对应的是可靠性要求很高的业务，取消HARQ-ACK不能被gNB正确接收将严重影响该业务的服务性能，无效的上行传输也影响系统的效率。
一种避免gNB和UE由于SFI传输失败的原因而确定的目标信道不同的方法是通过协议规定gNB和UE都仅将半静态帧格式配置的UL符号确定为备选符号。这样，备选符号的范围不受SFI传输失败与否的影响，可以保证DL SPS配置对应的业务性能。然而，SFI传输失败的概率并不高，也并非所有DL SPS配置都要传输性能要求很高的业务。一味地规定只有半静态帧格式配置的UL符号才能用作备选符号将影响取消HARQ-ACK的时延性能。比如根据该规定，时隙n的备选符号上没有可用的目标信道，gNB和UE只能在接下来的时间单元确定目标信道，取消HARQ-ACK的发送时间将较晚，影响SPS上业务的传输时延。
综上，如果SFI的指示结果用于确定备选符号，有利于取消HARQ-ACK的传输时延，进而提升业务的时延性能；但是在SFI传输失败的情况下，不利于取消HARQ-ACK的传输性能，进而影响业务的可靠性。鉴于gNB在一定程度上可以控制SFI的传输可靠性，例如通过将SFI映射到传输条件较好的无线资源，将DCI格式2_0的聚合等级调高可以提高其传输可靠性。gNB还可确定在DL SPS的配置上传输的业务性能。gNB可以评估SFI传输失败的情况下对业务性能影响是否在可接受范围。
如果SFI传输失败的情况下对SPS上传输的业务性能的影响在可接受范围内，gNB指示确定发送该SPS PDSCH的取消HARQ-ACK的目标信道时，备选符号要考虑SFI更改半静态配置的F符号的结果，即备选符号包括半静态配置的UL符号，以及半静态配置为F符号且被SFI更改为UL的符号。
如果SFI传输失败的情况下对SPS上传输的业务性能的影响不在可接受范围内，gNB指示该SPS PDSCH的取消HARQ-ACK的目标信道时，备选符号不考虑SFI更改半静态配置的F符号的结果，即备选符号仅包括半静态配置的DL符号。
gNB向UE指示确定某个SPS PDSCH的延迟HARQ-ACK的目标信道时，备选符号是否要考虑SFI更改半静态配置的F符号的结果，有利于保证业务服务可靠性和延迟性能的折衷，保证系统整体效率和业务服务性能。
关于第二指示信息
gNB可以通过第二指示信息指示确定发送该SPS PDSCH的取消HARQ-ACK的备选信道是否包括动态调度的PUSCH，和或是否包含动态调度PDSCH的HARQ-ACK的PUCCH。如果第二指示信息是第一状态，备选信道包括动态调度的PUSCH；如果第二指示信息是第二状态，备选信道不包括动态调度的PUSCH。如果第二指示信息是第三状态，备选信道包括动态调度PDSCH的HARQ-ACK的PUCCH；如果第二指示信息是第四状态，备选信道不包括动态调度PDSCH的HARQ-ACK的PUCCH。或者，第二指示信息指示确定发送该SPS PDSCH的取消HARQ-ACK的备选信道是否包括动态调度的PUSCH、是否包含动态调度PDSCH的HARQ-ACK的PUCCH是联合指示的。例如如果第二指示信息是第五状态，备选信道包括动态调度的PUSCH和动态调度PDSCH的HARQ-ACK的PUCCH；如果第二指示信息是第六状态，备选信道不包括动态调度的PUSCH和动态调度PDSCH的HARQ-ACK的PUCCH。第二指示信息可以在SPS的配置信息中发送给UE，可以在SPS的激活PDCCH中发送给UE。
PUSCH分为两种：一种是网络设备发送的下行控制信息DCI调度终端设备发送的PUSCH，为动态的授权调度。另一种是网络设备半静态配置终端设备发送的PUSCH，即网络设备通过免授权的调度方式指示终端设备发送PUSCH。PUSCH的发送方式可以参考3GPP TS38.214V16.3.0。
PUCCH分为四种：gNB为UE配置用于SPS HARQ-ACK的PUCCH资源、用于CSI反馈的PUCCH资源、用于动态调度PDSCH的HARQ-ACK的PUCCH资源、用于取消HARQ-ACK的PUCCH资源。配置用于SPS HARQ-ACK的PUCCH资源用于传送下行SPS配置的PDSCH的HARQ-ACK信息，当有SR传送需求时，该PUCCH中包括SR，除此之外，该PUCCH中不包含其它上行控制信息；配置用于CSI反馈的PUCCH资源用于传送信道状态信息，当有SR、下行SPS配置的PDSCH的HARQ-ACK信息的传送需求时，该PUCCH中包含SR、SPS配置的PDSCH的HARQ-ACK信息，该PUCCH中不包括动 态调度的PDSCH的HARQ-ACK；配置用于动态调度PDSCH的HARQ-ACK的PUCCH资源用于传送动态调度的PDSCH的HARQ-ACK，当有SR、下行SPS配置的PDSCH的HARQ-ACK、CSI信息中的任意项的传送需求时，该PUCCH中包含SR、SPS配置的PDSCH的HARQ-ACK、CSI信息。对任意一种PUCCH，资源配置中包括PUCCH的格式、时间上的符号长度，频率上的资源块位置等。包括用于SPS HARQ-ACK的PUCCH资源位于根据SPS PDSCH反馈时间差确定的时间单元，在该时间单元内PUCCH的位置由PUCCH的配置信息确定，用于CSI反馈的PUCCH由CSI反馈的周期或者半持续CSI的激活时间确定，用于动态调度PDSCH的HARQ-ACK的PUCCH资源的时间单元由动态调度信令确定等。一个时间单元中实际用于传输相同优先级等级HARQ-ACK的PUCCH只有一个。如果用于传输不同上行控制信息类型的多个PUCCH在时间上重叠，将在多个PUCCH中确定一个，用作传输所有这些上行控制信信息。如果待传输的PUCCH和PUSCH在时间上重叠，则在PUSCH中传输该PUCCH中的上行控制信息，丢弃PUCCH。不考虑输取消HARQ-ACK，参照3GPP TS38.213 V16.3.0，可以确定从基础时间单元起算，包括基础时间单元的各时间单元的PUCCH或者PUSCH，作为第二种备选信道。
与确定备选符号过程类似，如果备选信道是动态授权调度的PUSCH，或者是动态调度PDSCH的HARQ-ACK的PUCCH，备选信道的确定过程受动态授权调度信息的可靠性影响，网络设备和终端设备对备选信道的确定结果可能不同。例如动态授权调度如果没有被终端设备正确检测到，终端设备不认为有此备选信道，但网络设备将此动态授权调度的PUSCH或者动态调度PDSCH的HARQ-ACK的PUCCH作为备选信道，可能造成网络设备和终端设备最终确定的目标信道不同。但如果备选信道不包括任何动态授权调度的PUSCH或者动态调度PDSCH的HARQ-ACK的PUCCH，在动态调度授权的传输可靠性高的情况下，可能造成终端设备有效发送的动态授权调度的PUSCH或者动态调度PDSCH的HARQ-ACK的PUCCH无法承载取消HARQ-ACK，致使影响取消HARQ-ACK的及时发送，影响SPS承载业务的时延特性和调度流程。
鉴于gNB在一定程度上可以控制动态授权调度信息的传输可靠性，例如通过将动态授权调度信息的PDCCH映射到传输条件较好的无线资源，将相应 PDCCH的聚合等级调高来提高其传输可靠性。gNB还可确定在DL SPS的配置上传输的业务性能。gNB可以评估动态授权调度传输失败的情况下对业务性能影响是否在可接受范围。
如果动态授权调度传输失败的情况下对SPS上传输的业务性能的影响在可接受范围内，gNB指示确定发送该SPS PDSCH的取消HARQ-ACK的目标信道时，备选信道包括动态调度的PUSCH或者包括动态调度PDSCH的HARQ-ACK的PUCCH。
如果动态授权调度传输失败的情况下对SPS上传输的业务性能的影响不在可接受范围内，gNB指示该SPS PDSCH的取消HARQ-ACK的目标信道时，备选信道不包括动态调度的PUSCH或者不包括动态调度PDSCH的HARQ-ACK的PUCCH。
gNB向UE指示确定某个SPS PDSCH的延迟HARQ-ACK的目标信道时，备选信道是否包括动态调度的PUSCH或者包括动态调度PDSCH的HARQ-ACK的PUCCH，有利于保证业务服务可靠性和延迟性能的折衷，保证系统整体效率和业务服务性能。
步骤202、所述网络设备确定所述目标信道。
目标信道是基础PUCCH之后最早的备选信道。
备选信道包括以下第一种备选信道和第二种备选信道中的至少一种。
关于第一种备选信道
如果不为了传输取消HARQ-ACK，备选信道是不存在的，即通过预设规则在备选符号的范围内确定若干连续的符号作为备选信道，专用于发送取消HARQ-ACK。
gNB通过高层信令为UE配置用于SPS HARQ-ACK的PUCCH资源、用于CSI反馈的PUCCH资源、和用于动态调度PDSCH的HARQ-ACK的PUCCH资源。PUCCH资源配置中包括PUCCH的格式、时间上的符号长度，频率上的资源块位置等。gNB还可以通过高层信令为UE配置用于取消HARQ-ACK的PUCCH资源。以这些PUCCH资源配置的任意一种为参考，其配置对应的PUCCH包括的符号数是N 1，那么可以基础时间单元起算各时间单元的备选符号中确定位于基础PUCCH之后，最早的连续N 1个符号，作为第一种备选信道。
可选的，在基础时间单元内确定第一种备选信道。
为保证gNB可以正确在UE确定目标PUCCH接收被延迟发送的SPS PDSCH的HARQ-ACK，gNB和UE对于哪些符号是备选符号需要有统一的确定结果。在保证gNB和UE对备选信号有相同确定结果的基础上，gNB和UE使用相同的方式可以在备选符号中确定统一的第一种备选信道。
需要说明的是，第一种备选信道是所述原定PUCCH结束时刻之后，在所述基础时间单元中或后续的时间单元中第一个备选符号开始依次取连续的N 1个备选符号组成的信道，N 1是预设值。第一种备选信道包括位于同一个时间单元的N 1个备选符号。
关于第二种备选信道
即使不传输取消HARQ-ACK，该备选信道也存在。
终端设备发送的上行信道包括PUCCH和PUSCH。
如果第二种备选信道是半静态配置的信道，gNB和UE通过相同的预设方式可以确定统一的第二种备选信道。如果第二种备选信道是动态调度的信道，参考第二指示信息，gNB和UE可以确定统一的第二备选信道。
优选地，首先确定备选符号，再在备选符号的范围内确定目标信道。
