具体实施方式
下面将结合本申请实施例中的附图,对本申请实施例中的技术方案进行清楚地描述,显然,所描述的实施例是本申请一部分实施例,而不是全部的实施例。基于本申请中的实施例,本领域普通技术人员所获得的所有其他实施例,都属于本申请保护的范围。

下面结合附图,通过具体的实施例及其应用场景对本申请实施例提供的HARQ-ACK反馈方法进行详细地说明。
本申请实施例的方法应用于终端,如用户设备,用户设备(User Equipment,UE)可以指接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、无线通信设备、用户代理或用户装置。终端还可以是蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol,SIP)电话、无线本地环路(wireless local loop,WLL)站、个人数字助理(Personal Digital Assistant,PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备。
如图2所示,本申请实施例的一种HARQ-ACK反馈方法,应用于终端,包括:
步骤201,获取HARQ-ACK反馈采用的反馈策略;
步骤202,根据所述反馈策略,进行HARQ-ACK反馈。
通过步骤201和202,终端获取HARQ-ACK反馈采用的反馈策略,并确定对应的HARQ-ACK反馈行为,从而能有效利用各种HARQ-ACK反馈负荷减轻策略,保障HARQ-ACK传输及下行数据传输的性能。
可选地,步骤201包括:接收配置信令;其中,所述配置信令用于为所述终端配置HARQ-ACK反馈采用的反馈策略,所述HARQ-ACK与一个或一组调度配置对应。
这里,网络侧设备发送用于为终端配置反馈策略的配置信令,该反馈策略是终端执行与一个或一组调度Config对应的HARQ-ACK反馈时所采用的反馈策略。本步骤,终端通过获取网络侧设备发送的配置信令,明确了后续执行HARQ-ACK反馈时所采用的反馈策略。
这样,终端将通过接收网络侧设备发送的配置信令,由该配置信令指示一个或一组调度Config对应的HARQ-ACK反馈策略,并确定各种配置情况 下对应的HARQ-ACK反馈行为,从而能有效利用各种HARQ-ACK反馈负荷减轻策略,保障HARQ-ACK传输及下行数据传输的性能。
可选地,本申请实施例中,所述一个或一组调度配置为半持续调度SPS配置的情况下,所述反馈策略包括以下至少一项:
确认应答ACK跳过策略;
否定应答NACK跳过策略;
HARQ-ACK捆绑策略;
HARQ-ACK禁用策略;
非负荷减轻策略。
这里,ACK跳过策略、NACK跳过策略、HARQ-ACK捆绑策略和HARQ-ACK禁用策略均能够实现针对SPS Config的物理下行共享信道(SPS PDSCH)的HARQ-ACK反馈负荷减轻的目的。
ACK跳过(skipping)策略:当仅需要反馈针对SPS PDSCH的HARQ-ACK且所有HARQ-ACK的取值都为ACK时,终端实际不传输承载这些SPS PDSCH HARQ-ACK的物理上行控制信道PUCCH,否则正常反馈SPS PDSCH对应的HARQ-ACK。
NACK跳过策略:当仅需要反馈针对SPS PDSCH的HARQ-ACK且所有HARQ-ACK的取值都为NACK时,终端实际不传输承载这些SPS PDSCH HARQ-ACK的PUCCH,否则正常反馈SPS PDSCH对应的HARQ-ACK。
HARQ-ACK捆绑(bundling)策略:每个周期内的N个SPS PDSCH对应单个HARQ-ACK比特。可以认为这N个SPS PDSCH对应N项SPS Config,且这N项SPS Config的周期都相同,仅偏移不同。
HARQ-ACK禁用(disabling)策略:SPS PDSCH传输不用反馈HARQ-ACK,网络在配置传输资源和属性并激活SPS PDSCH时,确保对应的SPS PDSCH能正确传输。
而非负荷减轻策略是不考虑HARQ-ACK反馈负荷减轻,采用定义的HARQ-ACK码本构造流程针对各SPS PDSCH实际传输或传输机会反馈 HARQ-ACK。该非负荷减轻策略又可理解为正常的HARQ-ACK反馈策略。
如此,网络侧设备可为各个或各组SPS Config配置对应的反馈策略,通过配置信令告知终端,尤其是针对具备某种特征的业务数据(如周期性业务数据,或存在时延抖动的准周期性业务数据)配置SPS Config时。
可选地,本申请实施例中,考虑到动态调度配置,所述一个或一组调度配置为动态调度配置的情况下,所述反馈策略包括以下至少一项:
ACK跳过策略;
HARQ-ACK捆绑策略;
HARQ-ACK禁用策略;
非负荷减轻策略。
这里,各个反馈策略是针对动态调度的PDSCH的HARQ-ACK反馈,类似于SPS PDSCH,在此不再赘述。
而对于超可靠低延迟通信(Ultra Reliable and Low Latency Communication,URLLC)业务,由于反馈ACK的概率更高,动态调度配置的情况下优选ACK跳过策略。这里的动态调度,可以理解为使用调度DCI独立地指示各个或各组PDSCH的传输。一般情况下,调度DCI可以为UE特定的DCI。动态调度配置可以理解为针对动态调度的配置,包括高层参数配置。典型情况下,动态调度配置可以当做单个调度配置来处理。
对于终端未收到配置信令的情况,可选地,步骤201包括:
若未接收到用于配置HARQ-ACK反馈采用的反馈策略的配置信令,则确定默认策略为HARQ-ACK反馈采用的反馈策略;其中,所述默认策略包括以下至少一项:
ACK跳过策略;
NACK跳过策略;
HARQ-ACK捆绑策略;
HARQ-ACK禁用策略;
非负荷减轻策略。
例如,不论SPS配置还是动态调度配置,网络侧设备都能够基于HARQ-ACK反馈负荷减轻,仅配置采用ACK跳过策略、NACK跳过策略、HARQ-ACK捆绑策略、HARQ-ACK禁用策略中的至少一种。故,终端在未接收到配置信令的情况下,可直接根据默认策略进行HARQ-ACK反馈。
当然,对于未接收到配置信令的情况,HARQ-ACK反馈的默认策略不限于非负荷减轻策略,可预先定义或配置。
本申请实施例中,配置信令可以是高层信令,可以是下行控制信令DCI。或者,网络仍通过高层信令配置初始/缺省的HARQ-ACK反馈策略,但在DCI中动态指示了HARQ-ACK反馈策略时,实际使用DCI指示的HARQ-ACK反馈策略,否则使用高层信令配置的HARQ-ACK反馈策略。例如,对于SPS PDSCH,在对应的激活/重激活DCI中指示;对于下行动态调度,可以在调度DCI中指示。
在该实施例中,针对调度配置组的配置信令,可选地,所述调度配置是基于第一目标项进行分组的,所述第一目标项包括以下至少一项:
网络侧设备的分组配置;
传输优先级;
所属的物理上行控制信道PUCCH小区组;
所属的服务小区;
所属的带宽部分BWP。
如此,调度配置的分组可以是基于网络侧设备的分组配置进行的。如网络侧设备对于服务的业务数据特征相同或类似的一到多项SPS Config,将其配置为同一组。具体的,对于服务于同一周期性业务(但其周期并非协议中可配置的取值),或者存在时延抖动的准周期性业务的一到多项SPS Config,网络侧设备可以将它们配置为属于同一SPS Config组。可选地,同一SPS Config组对应的各项SPS Config可同时激活或去激活。可选地,某一SPS Config组可以考虑所有配置的SPS Config,或者仅考虑激活的SPS Config,即处于激活状态的SPS Config。
调度配置的分组可以是基于传输优先级进行的。其中传输优先级可以是调度配置的优先级,对应某种优先级的SPS Config可以隐式对应同一组。这里对应某种优先级的SPS Config,可以包括所有配置的SPS Config,或者仅包括激活的SPS Config。当为动态调度时,传输优先级可以是DCI中显式指示的优先级,或者,当DCI中未显式指示时,可以是配置或协议规定的默认优先级。
调度配置的分组可以是基于所属的PUCCH小区组(Cell Group)进行的。网络侧设备为每个PUCCH Cell Group配置HARQ-ACK反馈策略,此反馈策略应用于此PUCCH Cell Group对应的所有服务小区(Serving Cell)上配置的或激活的各个SPS Config,即网络侧设备为每个PUCCH Cell Group对应的所有Serving Cell上配置的或激活的各个SPS Config统一配置HARQ-ACK反馈策略。
调度配置的分组可以是基于所属的Serving Cell进行的。网络为每个Serving Cell配置HARQ-ACK反馈策略,此反馈策略应用于此Serving Cell上配置的或激活的各个SPS Config,即为某个Serving Cell上配置的或激活的各个SPS Config统一配置HARQ-ACK反馈策略。
调度配置的分组还可以是基于所属的BWP进行的。网络为每个BWP配置HARQ-ACK反馈策略,此反馈策略应用于此BWP上配置的或激活的各个SPS Config,即为某个BWP上配置的或激活的各个SPS Config统一配置HARQ-ACK反馈策略。
之后,对于各个SPS Config组,配置采用以下至少一项:ACK跳过策略、NACK跳过策略、HARQ-ACK捆绑策略、HARQ-ACK禁用策略、非负荷减轻策略,并通过配置信令告知终端。或者,对于各个SPS Config组,配置采用以下至少一项:ACK跳过策略、NACK跳过策略、HARQ-ACK捆绑策略、HARQ-ACK禁用策略,并通过配置信令告知终端,但当终端未接收到配置信令时,直接采用非负荷减轻策略进行HARQ-ACK反馈。
本申请实施例的方法中,可选地,所述反馈策略为HARQ-ACK捆绑策 略的情况下,所述一个或一组调度配置具有对应的捆绑标识。
以某项SPS Config或SPS Config组为例,当采用HARQ-ACK捆绑策略进行反馈时,网络侧设备为其配置对应的捆绑标识,如Bundle编号。此时捆绑标识相同的SPS Config或SPS Config组将进行HARQ-ACK bundling反馈。
当然,对于每组调度配置还可进一步划分多个调度配置子组,可选地,每组调度配置包括多个调度配置子组,每个调度配置子组均具有对应的捆绑标识,且所述调度配置子组中包括一个或多个调度配置。
即,当某个SPS Config组配置采用HARQ-ACK bundling策略时,可进一步针对此SPS Config组的各个SPS Config子组(如各个SPS Config或各个SPS Config子集)分别配置捆绑标识,如Bundle编号。这里的SPS Config子组可以是各个SPS Config或各个SPS Config子集,各个SPS Config子集可认为是针对此SPS Config组的进一步的集合划分。而捆绑标识相同的SPS Config或SPS Config子组将进行HARQ-ACK bundling反馈。
另外,该实施例中,终端通过配置信令确定反馈策略后,执行反馈处理。当每项SPS Config都确定了其对应的HARQ-ACK反馈策略(高层配置或DCI指示)时,或者,当下行动态调度或针对某种优先级的下行动态调度确定了其对应的HARQ-ACK反馈策略(高层配置或DCI指示)时,终端在需要HARQ-ACK反馈时执行对应反馈策略的相应操作。可选地,步骤202包括:
在HARQ-ACK反馈仅对应SPS物理下行共享信道PDSCH,或者,反馈的HARQ-ACK码本使用动态码本或者增强动态码本且所述HARQ-ACK码本包括与SPS PDSCH对应的HARQ-ACK的情况下,对于SPS PDSCH的HARQ-ACK反馈,执行以下至少一项:
若所述反馈策略为单一的反馈策略,则根据所述单一的反馈策略进行HARQ-ACK反馈;
若所述反馈策略为多种反馈策略,则确定目标反馈策略,并根据所述目标反馈策略进行HARQ-ACK反馈。
这里,对于HARQ-ACK反馈仅对应SPS PDSCH的情况,或者,使用动 态码本或增强动态码本,但HARQ-ACK码本包括与SPS PDSCH对应的HARQ-ACK的情况,会在本次反馈采用的反馈策略为单一的反馈策略时,根据该单一的反馈策略针对SPS PDSCH进行HARQ-ACK反馈;而为多种反馈策略时,先确定目标反馈策略,然后根据该目标反馈策略针对SPS PDSCH进行HARQ-ACK反馈。这里对于使用动态码本或增强动态码本,且HARQ-ACK码本包括与SPS PDSCH对应的HARQ-ACK的情况,可以理解为,当采用非负荷减轻策略时,HARQ-ACK码本包括与SPS PDSCH对应的HARQ-ACK比特序列,但采用其它反馈策略时,终端实际反馈的HARQ-ACK码本可能并不包含SPS PDSCH对应的HARQ-ACK比特序列,或者并不完整地包含SPS PDSCH对应的HARQ-ACK比特序列。
可选地,对于HARQ-ACK反馈仅对应SPS PDSCH的情况,不区分高层是配置了半静态码本,还是动态码本,或者增强动态码本,都可采用相同的HARQ-ACK反馈行为。
应该知道的是,对于上述两种情况,配置为HARQ-ACK disabling的SPS Config无需考虑,因为其不存在对应的HARQ-ACK反馈。所以此时HARQ-ACK码本不会涉及HARQ-ACK disabling策略。对于上述两种情况,SPS PDSCH的HARQ-ACK反馈采用的反馈策略涉及以下至少一项:ACK跳过策略、NACK跳过策略、HARQ-ACK捆绑策略、非负荷减轻策略。
为了简化HARQ-ACK反馈,一种可选的实施例为,终端不期望一个HARQ-ACK码本中的HARQ-ACK对应不同的HARQ-ACK反馈策略,或者,终端不期望一个HARQ-ACK码本中的HARQ-ACK对应HARQ-ACK反馈策略组合的任意一项(每项组合都涉及两种或两种以上的HARQ-ACK反馈策略)。因此,网络侧设备可以通过配置或调度等实现方式来保证终端组织和反馈的任意一个HARQ码本中的HARQ-ACK都只对应单种HARQ-ACK反馈策略。这里的单个HARQ-ACK码本可以理解为终端当采用非负荷减轻策略时组织且计划在某一时隙或子时隙等时间单元内反馈的HARQ-ACK比特序列。可选地,可将此HARQ-ACK比特序列(基于非负荷减轻策略)称之为 (一个HARQ-ACK码本的)名义HARQ-ACK比特序列。当采用配置的HARQ-ACK反馈策略实际组织此HARQ-ACK码本对应的(即实际需要反馈的)HARQ-ACK比特序列时,仅当HARQ-ACK比特序列不为空(即序列长度大于0)时才实际进行反馈。可选地,可将此HARQ-ACK比特序列(基于配置的反馈策略,或者后续提到的目标反馈策略)称之为(一个HARQ-ACK码本的)实际HARQ-ACK比特序列。在基于单一的反馈策略进行反馈时,可执行此反馈策略对应的行为。
可选地,所述根据所述反馈策略,进行HARQ-ACK反馈,包括:
所述单一的反馈策略为ACK跳过策略或NACK跳过策略的情况下,或所述目标反馈策略为ACK跳过策略或NACK跳过策略的情况下,执行以下至少一项:
当全部的SPS配置对应的HARQ-ACK被跳过时,跳过SPS PDSCH对应的HARQ-ACK码本的传输,或者,反馈第一比特数量的HARQ-ACK码本,所述第一比特数量的HARQ-ACK码本基于反馈策略确定;
当非全部的SPS配置对应的HARQ-ACK被跳过时,按照非负荷减轻策略生成HARQ-ACK码本。
这里,SPS PDSCH的HARQ-ACK反馈若统一采用ACK跳过策略或NACK跳过策略,将在全部的SPS Config对应的HARQ-ACK都可被skip(跳过)时,终端skip SPS PDSCH对应的HARQ-ACK码本的传输,否则终端上报完整的HARQ-ACK码本。这里提到的全部的SPS Config,可以理解为,当前HARQ-ACK码本对应的所有配置的或激活的SPS Config。这里的对应关系可以基于当前HARQ-ACK码本的名义HARQ-ACK比特序列来确定。
此外,在全部的SPS Config对应的HARQ-ACK都可被skip时,也可以反馈第一比特数量的HARQ-ACK码本,否则终端上报完整的HARQ-ACK码本。第一比特数量的HARQ-ACK码本基于反馈策略设置,包括第一比特数量的取值,以及HARQ-ACK码本中各个比特的取值的设置。一种可选的实施方式为,第一比特数量是1,即终端反馈的HARQ-ACK码本仅包含1比特。 可选地,此1比特HARQ-ACK码本当反馈采用ACK skipping策略时设置为ACK;当反馈采用NACK skipping策略时设置为NACK。其中1比特HARQ-ACK可采用PUCCH format 0/1来承载。该方式可应用于当PUCCH传输处于Unlicensed band时,此时终端在不同情况下都需要反馈HARQ-ACK PUCCH(即执行承载HARQ-ACK比特序列的PUCCH传输),但当可skip时(即当采用ACK skipping且所有HARQ-ACK都为ACK,或者当采用NACK skipping且所有HARQ-ACK都为NACK时)可通过减少HARQ-ACK反馈比特来减轻反馈负荷,进而减少终端功耗并降低系统内上行干扰。当终端在HARQ-ACK PUCCH传输之前作LBT失败时,网络侧设备无法正确接收PUCCH,此时网络侧设备可判断出本次LBT失败,进而通过重传等机制来获取未成功传输的HARQ-ACK。
可选地,所述根据所述反馈策略,进行HARQ-ACK反馈,包括:
所述单一的反馈策略为HARQ-ACK捆绑策略的情况下,或所述目标反馈策略为HARQ-ACK捆绑策略的情况下,在生成第一服务小区对应的HARQ-ACK比特序列过程中,基于第二目标项进行循环;
其中,所述第二目标项包括以下至少一项:
SPS配置标识;
捆绑标识;
SPS配置组标识;
其中,所述第一服务小区为生成HARQ-ACK码本时涉及的各个服务小区。
这里,对于SPS PDSCH的HARQ-ACK反馈统一采用HARQ-ACK bundling策略的情况,会在生成第一服务小区对应的HARQ-ACK比特序列时,基于以下至少一项:SPS配置标识、捆绑标识(如Bundle编号)、SPS配置组标识(如SPS Config组号),进行循环。即,对于Serving cell1(生成HARQ-ACK码本时涉及的一个服务小区),在组织HARQ-ACK码本中Serving cell1对应的HARQ-ACK比特序列时可以基于上述第二目标项至少之一进行 循环,将各次循环输出的HARQ比特序列按循环顺序进行首尾相连。
其中,基于SPS配置标识(如SPS Config index)循环,可基于SPS Config index从小到大循环或从大到小循环;此时某个Bundle对应的HARQ-ACK比特可占据此Bundle对应的最小SPS Config index或最大SPS Config index或指定SPS Config index对应的HARQ-ACK比特位置,此Bundle对应的其它SPS Config index在循环中被忽略。某个Bundle(可由捆绑标识或Bundle编号来指示)对应的HARQ-ACK比特的取值可以基于后面的操作确定。可选地,当某个Bundle对应的HARQ-ACK被确定为ACK时,此Bundle对应的HARQ-ACK比特取值可以为1;当某个Bundle对应的HARQ-ACK被确定为NACK时,此Bundle对应的HARQ-ACK比特取值可以为0。
基于捆绑标识(如Bundle编号)循环,可基于Bundle编号从小到大循环或从大到小循环。
基于SPS配置组标识(如SPS Config组号),可基于SPS Config组号从小到大循环或从大到小循环。某个SPS Config组可以对应单个或多个捆绑标识(对于后者,可以理解为此SPS Config组包含的某个SPS Config子集对应单个捆绑标识)。当多个SPS Config组或SPS Config子集对应相同的捆绑标识时,此捆绑标识对应的HARQ-ACK比特可占据此捆绑标识对应的最小SPS配置组标识/SPS Config子集索引,或者最大SPS配置组标识/SPS Config子集索引,或者指定SPS配置组标识/SPS Config子集索引对应的HARQ-ACK比特位置,此捆绑标识对应的其它SPS配置组标识/SPS Config子集索引在循环中被忽略。对于某个SPS Config组包含多个SPS Config子集的情况,可以进一步针对此SPS Config组包含的各个SPS Config子集,或涉及的各个捆绑标识按从小到大循环或从大到小循环,在此不作赘述。
此外,统一采用HARQ-ACK bundling策略时,在组织HARQ-ACK码本时,最外层循环可以仍然基于Serving cell index,例如基于Serving cell index从小到大循环或从大到小循环,然后再针对每个Serving cell index生成其对应的HARQ-ACK比特序列,各Serving cell index对应的HARQ-ACK比特序 列按循环顺序进行首尾相连,在此不再赘述。
可选地,该实施例中,所述捆绑标识对应的HARQ-ACK根据以下至少一项确定:
在至少一目标传输块的解码结果为ACK的情况下,所述捆绑标识对应的HARQ-ACK为ACK;
在全部的目标传输块的解码结果为NACK的情况下,所述捆绑标识对应的HARQ-ACK为NACK。
或者,可选地,所述捆绑标识对应的HARQ-ACK根据以下至少一项确定:
在全部的目标传输块的解码结果为ACK的情况下,所述捆绑标识对应的HARQ-ACK为ACK;
在至少一目标传输块的解码结果为NACK的情况下,所述捆绑标识对应的HARQ-ACK为NACK。
其中,所述目标传输块为N个周期内,所有SPS PDSCH时机对应的传输块,所述SPS PDSCH时机与第一SPS配置对应,所述第一SPS配置对应第一捆绑标识,所述周期对应第一捆绑标识。
如此,对于某个Bundle编号,其对应的HARQ-ACK可基于如下方式确定:基于此Bundle对应的最小SPS Config index、最大SPS Config index或指定SPS Config index确定的周期(包括起始时刻和时长),在N个周期(如N=1)内此Bundle编号对应的各个SPS Config对应的SPS PDSCH时机(occasion)对应为单个Bundle instance(即这些SPS PDSCH时机可认为从属于此Bundle instance)。对于某个Bundle instance的某个传输块i(典型情况下只考虑单码字传输,即单个传输块,此时i=0),当此Bundle instance对应的所有SPS PDSCH occasion中至少有一个SPS PDSCH occasion的传输块i解码结果为ACK时,将此Bundle instance的传输块i对应的HARQ-ACK设置为ACK;否则设置为NACK。可选地,也可以要求当此Bundle instance对应的所有SPS PDSCH occasion的传输块i解码结果为ACK时,才将此Bundle  instance的传输块i对应的HARQ-ACK设置为ACK;否则设置为NACK。针对每个Bundle instance的每个传输块索引(即上述i),可在实际反馈的HARQ-ACK码本中包含对应的单个HARQ-ACK比特。可选地,当某个Bundle instance的某个传输块索引i对应的HARQ-ACK设置为ACK时,对应的HARQ-ACK比特取值可以为1;当某个Bundle instance的某个传输块索引i对应的HARQ-ACK设置为NACK时,对应的HARQ-ACK比特取值可以为0。当某个HARQ-ACK码本中需要包含某一捆绑标识或Bundle编号对应的多个Bundle instance对应的HARQ-ACK时,可进一步将此捆绑标识或Bundle编号对应的各个Bundle instance按时间从前往后或从后往前或指定的顺序循环遍历,输出此捆绑标识或Bundle编号对应的各个Bundle instance对应的HARQ-ACK比特并按循环顺序进行首尾相连,得到此捆绑标识或Bundle编号对应的HARQ-ACK比特序列,在此不作赘述。当然,若采用双码字传输,捆绑标识将针对每个码字反馈HARQ-ACK,即上述i=0或1。
可选地,所述单一的反馈策略为非负荷减轻策略的情况下,基于现有技术或规定来组织HARQ-ACK码本并上报即可。
该实施例中,可选地,终端可支持一个HARQ-ACK码本中的HARQ-ACK对应一种或多种HARQ-ACK反馈策略。当一个HARQ-ACK码本中的HARQ-ACK对应多种HARQ-ACK反馈策略时,在组织和反馈此HARQ-ACK码本时,终端将确定最终使用的目标反馈策略。可选地,所述目标反馈策略为:预定义或预配置的反馈策略,或者,
基于预设规则,在所述多种反馈策略中确定的反馈策略。
具体的,一方面,该目标反馈策略可以是由协议规定或高层预配置的反馈策略。例如,当某个HARQ-ACK码本中的HARQ-ACK对应两种或以上的HARQ-ACK反馈策略时,协议规定或高层预配置某一反馈策略即为目标反馈策略,如非负荷减轻策略。此时终端在判断出当前待组织的HARQ-ACK码本对应两种或以上的HARQ-ACK反馈策略时,不关注这些HARQ-ACK反馈策略具体是哪些,直接采用非负荷减轻策略,完整上报HARQ-ACK码本对 应的所有SPS PDSCH的HARQ-ACK。
又或者,如表1,示例性地给出了单个HARQ-ACK码本可能对应的各种HARQ-ACK反馈策略组合对应的实际采用的HARQ-ACK反馈策略(即目标反馈策略),这种对应关系可以由协议规定,或者通过高层信令配置。
Figure PCTCN2021122766-appb-000001
表1
故终端通过配置信令,在判断出当前待组织的HARQ-ACK码本对应两种或以上的HARQ-ACK反馈策略时,基于这些对应的HARQ-ACK反馈策略构成的HARQ-ACK反馈策略组合,通过表1找到对应的行,就能够确定对应的目标反馈策略,用于实际组织HARQ-ACK码本。
另一方面,目标反馈策略是基于预设规则,在多种反馈策略中确定的。例如,协议规定或高层预配置每种HARQ-ACK反馈策略对应的索引,一种可能的索引为:0-非负荷减轻策略;1-HARQ-ACK bundling;2-NACK skipping;3-ACK skipping。预设规则可以是以下一种或多种:
选择索引最小或最大的HARQ-ACK反馈策略;
当存在某种HARQ-ACK反馈策略(如非负荷减轻策略)时,总是选择这种HARQ-ACK反馈策略;
当存在某种或某些HARQ-ACK反馈策略(如同时存在ACK skipping和NACK skipping)时,总是选择指定的HARQ-ACK反馈策略(如非负荷减轻策略)。
另外,可选地,所述目标反馈策略包括所述多种反馈策略的情况下,按照各反馈策略生成各SPS配置对应的HARQ-ACK码本。这里可以理解为,当前HARQ-ACK码本对应的各个SPS Config按各自配置的HARQ-ACK反馈策略来执行对应的HARQ-ACK反馈。各个SPS Config基于其配置的HARQ-ACK反馈策略输出的HARQ-ACK比特序列可基于预定义的循环顺序首尾相连,形成完整的HARQ-ACK码本。
当HARQ-ACK码本仅包含针对SPS PDSCH的HARQ-ACK时,组织码本对应的HARQ-ACK比特序列的循环顺序可以为:Serving cell index-SPS PDSCH configuration index-DL slot index,即先基于DL slot index(下行时隙索引)进行从小到大或从大到小的循环,然后基于SPS PDSCH configuration index(SPS配置索引)进行从小到大或从大到小的循环,最后基于Serving cell index(服务小区索引)进行从小到大或从大到小的循环;各次循环输出的HARQ比特序列依次首尾相连形成单一的HARQ-ACK比特序列,作为待反馈的HARQ-ACK码本。其上报示例可参见图3。
当然,对于某些HARQ-ACK反馈策略组合,如果各项SPS Config按各自配置的HARQ-ACK反馈策略各自上报,可能会导致网络侧设备针对较多码本大小(Codebook Size;对应上述待反馈的HARQ-ACK码本对应的单一HARQ-ACK比特序列的长度)的盲检,或导致比特映射(PDSCH接收<->HARQ-ACK比特)的混淆。因此,可对上报操作作进一步限制。可选地,
在所述HARQ-ACK码本对应的SPS PDSCH仅基于ACK跳过策略和NACK跳过策略反馈,且对应的SPS配置或SPS配置组均跳过HARQ-ACK 时,
跳过SPS PDSCH对应的HARQ-ACK码本的传输;或者,
反馈第二比特数量的HARQ-ACK加第三比特数量的HARQ-ACK码本,所述第二比特数量的HARQ-ACK对应第一SPS配置或SPS配置组,所述第三比特数量的HARQ-ACK对应第二SPS配置或SPS配置组,所述第一SPS配置或SPS配置组采用ACK跳过策略,所述第二SPS配置或SPS配置组采用NACK跳过策略;或者,
反馈第四比特数量的HARQ-ACK码本,所述第四比特数量的HARQ-ACK码本用于向网络侧设备指示原始HARQ-ACK码本均跳过。
这里,当HARQ-ACK码本对应的SPS PDSCH同时涉及ACK skipping和NACK skipping且仅涉及这两种HARQ-ACK反馈策略时,仅当两种HARQ-ACK反馈策略对应的SPS Config或SPS Config组都可skip对应的HARQ-ACK时,终端跳过SPS PDSCH对应的HARQ-ACK码本的传输。或者,对于ACK skipping对应的一到多项SPS Config反馈第二比特数量(如1比特)HARQ-ACK(可选地,取值为ACK),对于NACK skipping对应的一到多项SPS Config反馈第三比特数量(如1比特)HARQ-ACK(可选地,取值为NACK),构成预定义或预配置比特数量(如2比特)的HARQ-ACK码本。这里,预定义或预配置比特数量至少为第二比特数量加第三比特数量。其中ACK skipping对应的HARQ-ACK比特与NACK skipping对应的HARQ-ACK比特之间的顺序可以由协议规定或基于高层配置。又或者,终端反馈第四比特数量(如1比特)HARQ-ACK的HARQ-ACK码本,此1比特用于向网络侧设备指示原始HARQ-ACK码本都已经被跳过(skipped),其取值可以由协议规定或基于高层配置,例如设置为ACK。其中,原始HARQ-ACK码本是对应SPS PDSCH的HARQ-ACK码本,可选地,可以为当采用非负荷减轻策略时SPS PDSCH对应的HARQ-ACK比特序列,或者,前文中提到的HARQ-ACK码本的名义HARQ-ACK比特序列。当然,若HARQ-ACK码本对应的SPS PDSCH不满足上述条件(上述条件即:两种HARQ-ACK反馈策 略对应的SPS Config或SPS Config组都可skip对应的HARQ-ACK),终端会反馈包括原始HARQ-ACK码本的全部HARQ-ACK。
当然,采用动态码本或增强动态码本时,反馈的HARQ-ACK中仅尾部SPS PDSCH对应的HARQ-ACK比特序列作上述替代。
对于目标反馈策略为多种反馈策略的情况,可选地,在所述HARQ-ACK码本对应的SPS PDSCH基于ACK跳过策略和/或NACK跳过策略,以及其他反馈策略反馈,且ACK跳过策略和/NACK跳过策略对应的SPS配置或SPS配置组均跳过HARQ-ACK时,反馈的SPS PDSCH对应的HARQ-ACK码本中仅包括基于所述其他反馈策略得到的HARQ-ACK比特序列;
所述其他反馈策略包括以下至少一项:
HARQ-ACK捆绑策略;
HARQ-ACK禁用策略;
非负荷减轻策略。
这里,其它HARQ-ACK反馈策略是上述ACK跳过策略、NACK跳过策略、HARQ-ACK捆绑策略、HARQ-ACK禁用策略、非负荷减轻策略中,除ACK跳过策略和NACK跳过策略之外的至少一策略。当HARQ-ACK码本对应的SPS PDSCH涉及ACK skipping和/或NACK skipping,以及其它HARQ-ACK反馈策略时,仅当ACK skipping和/或NACK skipping对应的SPS Config或SPS Config组都可skip对应的HARQ-ACK时,终端在组织HARQ-ACK码本时,会忽略对应的HARQ-ACK比特序列,仅针对剩余SPS Config或SPS Config组按配置的HARQ-ACK反馈策略组织对应的HARQ-ACK比特序列;否则终端反馈包括对应的SPS PDSCH的HARQ-ACK码本的全部HARQ-ACK。
此外,对于目标反馈策略为多种反馈策略的情况,当HARQ-ACK码本对应的SPS PDSCH不涉及ACK skipping和NACK skipping时,各SPS Config或SPS Config组按各自配置的HARQ-ACK反馈方案进行上报即可。HARQ-ACK bundling对应的SPS Config或SPS Config组的HARQ-ACK比特 序列的组织可参考上述处理。
由于半静态码本即Type-1码本,或者一次性(One-shot)码本即Type-3码本,其码本大小,即对应的HARQ-ACK码本中包含的比特数基于半静态配置。故当这些码本中至少一个HARQ-ACK比特对应于SPS PDSCH接收时,因为与SPS PDSCH接收对应的HARQ-ACK比特可能较为分散,会和动态调度PDSCH的HARQ-ACK比特交错在一起。在跳过与SPS PDSCH接收对应的HARQ-ACK比特时易导致码本中剩余比特存在映射混淆(PDSCH接收或HARQ进程<->HARQ-ACK比特之间的映射)的问题。可选地,步骤102包括:
在反馈的HARQ-ACK码本使用半静态码本或者一次性码本的情况下,若生成的HARQ-ACK码本中各比特均对应NACK或者ACK,则跳过本次反馈;或者,
反馈第五比特数量的HARQ-ACK码本,所述第五比特数量的HARQ-ACK码本为原始HARQ-ACK码本;或者,
反馈第六比特数量的HARQ-ACK码本,所述第六比特数量的HARQ-ACK码本用于向网络侧设备指示原始HARQ-ACK码本均跳过。
因此,当HARQ-ACK码本中的HARQ-ACK比特取值都为NACK或者ACK时,终端可忽略本次反馈;或者,反馈第六比特数量(如1比特)的HARQ-ACK码本,此1比特用于向网络侧设备指示原始HARQ-ACK码本都已经skipped(被跳过),其取值可以由协议规定或基于高层配置。可选地,当HARQ-ACK码本中的HARQ-ACK比特取值都为NACK时第六比特数量(如1比特)的HARQ-ACK码本中的比特设为NACK,都为ACK时第六比特数量(如1比特)的HARQ-ACK码本中的比特设为ACK;否则正常上报。而对于One-shot码本,当配置了上报NDI时,HARQ-ACK码本中的NDI比特不参与上述NACK/ACK判断。
当然,在反馈的HARQ-ACK码本使用半静态码本或者一次性码本的情况下,反馈也不限于上述方式,也可按照非负荷减轻策略组织常规 HARQ-ACK码本并反馈。
可选地,为了避免终端判断HARQ-ACK码本中比特的取值,以及在某些条件满足时执行跳过操作,降低终端实现的复杂度,终端不期望当配置采用半静态(Type-1)码本和/或One-shot(Type-3)码本时,为SPS Config配置ACK skipping/NACK skipping/HARQ-ACK bundling/HARQ-ACK disabling等HARQ-ACK反馈策略,即配置除正常HARQ-ACK反馈之外的其它HARQ-ACK反馈策略,或者即配置除非负荷减轻策略之外的其它HARQ-ACK反馈策略。可选地,可以允许上述配置,但终端不期望配置了ACK skipping/NACK skipping/HARQ-ACK bundling/HARQ-ACK disabling等HARQ-ACK反馈策略的SPS Config对应的HARQ-ACK与半静态码本和/或One-shot码本一起上报,即通过实现避免这些SPS Config对应的HARQ-ACK与半静态码本和/或One-shot码本的融合。
对于动态(Type-2)码本或增强动态码本,与SPS PDSCH对应的HARQ-ACK比特序列附在与动态调度PDSCH对应的HARQ-ACK比特序列之后。此时,与SPS PDSCH对应的HARQ-ACK比特序列的处理与HARQ-ACK反馈仅对应SPS PDSCH的处理类似,在此不再赘述。
该实施例中,当下行动态调度或针对某种优先级的下行动态调度确定了其对应的HARQ-ACK反馈策略时,可以将整个HARQ-ACK码本中与下行动态调度对应的HARQ-ACK比特序列当做单项SPS Config或单个SPS Config组对应的HARQ-ACK比特序列,与此HARQ-ACK码本对应的其它SPS Config或SPS Config组对应的HARQ-ACK比特序列一起沿用HARQ-ACK反馈仅对应SPS PDSCH时的处理即可。
这样,该实施例通过引入针对SPS Config的HARQ-ACK反馈策略的个性化配置方法,并确定了混合配置时对应的HARQ-ACK反馈行为,可以有效降低SPS PDSCH HARQ-ACK反馈负荷。
