Description

混合自动重传请求反馈方法、通信设备及可读存储介质 【技术领域】
本申请涉及通信领域，特别是涉及一种混合自动重传请求反馈方法、通信设备及可读存储介质。
【背景技术】
第五代移动通信系统(5G NR)包括三大应用场景，即增强移动宽带(eMBB:Enhanced Mobile Broadband)、大规模机器类型通信(mMTC:Massive Machine Type Communication)以及低时延高可靠(URLLC:Ultra-reliable low-latency communication)。URLLC有两个基本特点，即高可靠和低时延，例如10 -5或10 -6量级的BLER性能，0.5ms或1ms的空口传输时延。
半静态调度(Semi-Persistent Scheduling，SPS)允许半静态配置无线资源，并将该资源周期性地分配给用户设备(UserEquipment，UE)。SPS有“一次分配，多次使用”的特点，基站为UE配置SPS资源并激活SPS后，每过一个SPS周期，UE就使用该SPS资源来收或发数据。基站无需再为后续的SPS资源重新下发下行控制信息(Downlink Control Information，DCI)来指定分配的资源。
现有技术中，如果UE被配置了在时隙(slot)n接收SPS物理下行共享信道(Physical Downlink Share Channel，PDSCH)，则UE会在slot n+k1通过物理上行控制信道(Physical uplink control channel，PUCCH)传输该SPS PDSCH相对应的混合自动重传请求(Hybrid automatic repeat request，HARQ)反馈信号(也可以被称为HARQ-ACK)。其中k1为时序参数，表示一定数量的slot数目，由DCI中的PDSCH-to-HARQ_feedback timing indicator字段来配置，或者由无线资源控制(Radio Resource Control，RRC)参数dl-DataToUL-ACK来配置(DCI Format1_2时RRC参数为dl-DataToUL-ACKForDCIFormat1_2)。
由于SPS PDSCH“一次分配，多次使用”的特点，k1的配置仅在启动/激活(activate)SPS PDSCH的DCI格式(format)中配置，其余SPS PDSCH均沿用activate DCI format中的配置来进行HARQ反馈，也就是对于每个SPS PDSCH来讲它们的k1取值是相同的。基于这种特性，在时分双工(Time-Division Duplex，TDD)场景下就会出现冲突的现象，如果回应SPS PDSCH的HARQ反馈信号 恰巧落到了TDD的非上行slot或非上行符号(symbol)内，按照目前的协议规定会将该HARQ反馈丢弃。
举例说明，如图1所示，假设TDD slot配置为‘DDDUU’，其中D代表下行(Downlink，DL)，U代表上行(Uplink，UL)，并且启动(activate)SPS PDSCH的DCI format中指示k1＝2，则HARQ反馈信号的位置如下图所示。在DL#1发送的SPS PDSCH，基于k1＝2需要在DL#3的位置发送相应的HARQ反馈信号，但由于DL#3为下行slot则该HARQ反馈信号需要被丢弃。以此类推，在DL#2和DL#3位置发送的SPS PDSCH，分别在UL#1和UL#2的位置发送相应的HARQ反馈信号，可以正常发送HARQ反馈信号给基站。
冲突导致的丢弃HARQ反馈信号会影响对应的PDSCH的性能，特别是在SPS PDSCH周期变短，HARQ反馈冲突出现地更加频繁的情况下。

如图3所示，本申请混合自动重传请求反馈方法第一实施例包括：
S11：接收来自于基站的多个时序参数。
本实施例应用于用户设备侧。每个时序参数用于指示第一时间单元和第二时间单元之间的时间间隔，第一时间单元为用户设备接收来自于基站的下行传输的时间单元，第二时间单元为用户设备向基站发送下行传输的HARQ反馈信号的时间单元。时序参数/时间单元的单位可以为时隙或符号，为便于描述，下文均以时隙作为时序参数/时间单元的单位进行说明，实际应用中也可以采用其他类型。下行传输可以为SPSPDSCH。
时序参数k1可以为整数，其数值表示第一时间单元和第二时间单元之间的时隙数量。如果涉及到多个时间单元的下行传输的聚合，那么用户设备会将聚合的多个时间单元作为一个整体来进行HARQ反馈，并且将上述聚合的多个时间单元中的最后一个作为第一时间单元。举例说明，当配置了 pdsch-AggregationFactor时，被聚合的pdsch-AggregationFactor个SPS PDSCH按照1个SPS PDSCH做处理。即从slot n到slot n-pdsch-AggregationFactor+1的SPS PDSCH对应的HARQ均在同一个UL slot n+k1上发送。
多个时序参数可以为单个SPS配置(即接收到的SPS PDSCH对应的SPS配置)的时序参数集合。这种情况下，基站可以在配置该SPS配置的时候向用户设备发送包含多个时序参数的时序参数集合。时序参数集合中不同的时序参数互不相同，时序参数集合中时序参数的数量可以由DCI或者高层信令(例如，RRC信令)指定，在此不做限制。多个时序参数可以为多个SPS配置的时序参数，每个SPS配置的时序参数的数量可以为一个或者多个。这种情况下，用户设备接收到的SPS PDSCH对应的SPS配置(以下简称当前SPS配置)可以为这些SPS配置中的一个。
S12：从多个时序参数中选择一个不冲突的时序参数。
用户设备在收到下行传输之后，根据解码情况确定对应的HARQ反馈信号。若可以正常解码，则对应的HARQ反馈信号为HARQ确认信号(ACK)；否则对应的HARQ反馈信号为HARQ否认信号(NACK)。若启用了下行传输聚合，则为聚合的所有下行传输生成对应的HARQ反馈信号，其中包括每个下行传输的HARQ反馈信息。
用户设备收到下行传输后，根据收到下行传输的第一时间单元，以及已配置的每个时序参数，可以确定每个时序参数对应的第二时间单元。若某个时序参数对应的第二时间单元在TDD配置中是下行的，那么用户设备无法在该时序参数对应的第二时间单元发送HARQ反馈信号，意味着该时序参数与TDD配置存在冲突，简称该时序参数是冲突的。反之，若某个时序参数对应的第二时间单元在TDD配置中是上行的，那么用户设备能够在该时序参数对应的第二时间单元发送HARQ反馈信号，意味着该时序参数与TDD配置不存在冲突，简称该时序参数是不冲突的。
用户设备可以采用上述方式来判断各时序参数是否是冲突的，以在已配置的多个时序参数中寻找不冲突的时序参数。若未在多个时序参数中找到不冲突的时序参数，则放弃发送并丢弃HARQ反馈信号并丢弃。
以下对从当前SPS配置的时序参数集合中选择和从多个SPS的时序参数中选择两种情况分别描述，实际应用中这两种情况可以结合。
从当前SPS配置的时序参数集合中选择：
如图4所示，在本申请一具体实施例中，S12包括：
S121：选择时序参数集合中的第一个时序参数尝试发送HARQ反馈信号。
第一个时序参数也可以被称为默认时序参数，用户设备优先选择默认时序参数。具体的，用户设备确定默认时序参数对应的第二时间单元并尝试发送HARQ反馈信号。如果默认时序参数对应的第二时间单元是上行的，那么可以成功发送HARQ反馈信号，无需再选择其他时序参数；如果默认时序参数对应的第二时间单元是下行的，就是说默认时序参数是冲突的，跳转到S122。
S122：从时序参数集合中除第一个时序参数之外的其他时序参数中选择一个不冲突的时序参数。
用户设备可以遍历时序参数集合中除默认时序参数之外其他时序参数直至找到不冲突的时序参数。
举例说明，如图5所示，TDD配置为DDDDDDDDUU，即在一个无线帧中，前8个时隙为下行，最后2的时隙为上行。为UE配置的时序参数集合K1_set＝{6，8，7，3，5}，对于DL#1上调度的SPS PDSCH来说，k1＝6时对应DL#7显然不符合发送HARQ反馈信号的条件，当k1＝8时可以在UL#1中发送HARQ反馈信号；同样地，对于DL#5上调度的SPS PDSCH来说k1＝5时可以成功传输相应的HARQ反馈信号。
如图6所示，在本申请另一具体实施例中，S12包括：
S131：将时序参数集合中的时序参数按照指定顺序进行排序。
指定顺序可以为从大到小。
S132：选择上一个下行传输使用的时序参数尝试发送HARQ反馈信号。
S133：若出现冲突，则依次选择上一个下行传输使用的时序参数之后的时序参数直至找到不冲突的时序参数。
由于在TDD的配置中，上行slot或symbol一般处在一个无线帧的结尾处，那么对于下行传输来说，从第一个下行slot开始按slot number依次递增，对应的不冲突的k1的值是处于一个递减的状态。以图5给出的TDD配置为例，假设在下行slot DL#1、2、3上的下行传输均分配在UL#1上发送HARQ反馈信号，那么它们对应的k1的取值分别为：8、7、6。
考虑到TDD场景的这种情况，为减少UE检索不冲突的k1的复杂度，可以将基站配置的时序参数集合的k1按照取值从大到小的顺序排列，UE在为每一个SPS PDSCH选取合适的k1反馈时序时，按照K1_set内部的排序依次筛选合 适的k1。
继续使用图5为例进行说明，假设排序之后的时序参数集合K1_set＝{8，7，6，5，3}，对于DL#1上的SPS PDSCH，先判断k1＝8时是否可以成功反馈HARQ，根据图5给出的TDD配置，k1＝8是可以在UL#1上进行HARQ传输，则DL#1对应的k1＝8。接下来，对于DL#3上的SPS PDSCH，先在DL#1对应的k1＝8的基础上做判断，此时k1＝8时对应的第二时间单元为下一个无线帧的DL#1，无法做HARQ反馈，则选取K1_set内8之后的7，判断k1＝7时是否可以反馈，以此类推。
UE同时存在多个SPS配置的情况下，可以从多个SPS配置的时序参数中选择：
如图7所示，在本申请又一具体实施例中，S12包括：
S141：选择下行传输对应的SPS配置的时序参数尝试发送HARQ反馈信号。
优先选择当前SPS配置的时序参数。具体的，用户设备确定当前SPS配置的时序参数对应的第二时间单元并尝试发送HARQ反馈信号。如果当前SPS配置的时序参数对应的第二时间单元是上行的，那么可以成功发送HARQ反馈信号，无需再选择其他时序参数；如果当前SPS配置的时序参数对应的第二时间单元是下行的，就是说默认时序参数是冲突的，跳转到S142。
S142：若出现冲突，则从其他SPS配置的时序参数中选择一个不冲突的时序参数。
用户设备可以遍历其他SPS配置的时序参数直至找到不冲突的时序参数。
可选的，用户设备可以将所有SPS配置的时序参数按从大到小或从小到大的顺序进行排序，再依次从当前SPS配置的时序参数之后的时序参数开始，依序遍历其他SPS配置的时序参数寻找不冲突的时序参数。
如图8所示，在本申请又一具体实施例中，S12包括：
S151：选择下行传输对应的SPS配置的时序参数尝试发送HARQ反馈信号。
本例中与图7对应的具体实施例相同或相似的部分可参考图7对应的具体实施例中的描述，在此不再重复。
S152：若出现冲突，则对下行传输对应的SPS配置的时序参数进行调整以寻找不冲突的调整后时序参数。
具体调整方式可参考后续实施例的描述。
若找到则跳转到S153，否则跳转到S154。
S153：使用不冲突的调整后时序参数发送HARQ反馈信号。
S154：从其他SPS配置的时序参数中选择一个不冲突的时序参数。
确定不冲突的时序参数之后，UE可以根据是否允许出现HARQ反馈次序颠倒的情况决定是否执行HARQ反馈次序颠倒判定。具体的，若允许出现HARQ反馈次序颠倒的情况，则无需执行HARQ反馈次序颠倒判定；若不允许出现HARQ反馈次序颠倒的情况，则需要执行HARQ反馈次序颠倒判定。
如图9所示，HARQ反馈次序颠倒判定包括：
S161：判断不冲突的时序参数是否会造成HARQ反馈信号与另一HARQ反馈信号的反馈次序颠倒。
反馈次序颠倒是指下行传输的顺序与对应的HARQ反馈顺序相反。举例说明，若下行传输1在下行传输2之前，但最终确定的下行传输1的HARQ反馈信号在下行传输2的HARQ反馈信号之后发送，意味着出现了HARQ反馈次序颠倒。
若会造成HARQ反馈次序颠倒，则跳转到S162，否则不需要放弃，跳转到S13。
S162：放弃发送HARQ反馈信号与另一HARQ反馈信号中的一个。
如何确定放弃的HARQ反馈信号在此不做限定。
若不冲突的时序参数的数量大于1，只要有一个不冲突的时序参数不会造成HARQ反馈次序颠倒，就可以使用它发送HARQ反馈信号；反之若所有的不冲突的时序参数都会造成HARQ反馈次序颠倒，才会放弃一个HARQ反馈信号。
S13：使用不冲突的时序参数发送HARQ反馈信号。
在不冲突的时序参数对应的第二时间单元发送HARQ反馈信号。
通过本实施例的实施，UE可以从多个时序参数中寻找不冲突的时序参数以发送HARQ反馈信号，与现有技术中固定的单个时序参数相比，可以减少HARQ反馈信号因冲突被丢弃的情况，改善PDSCH的性能。
如图10所示，本申请混合自动重传请求反馈方法第二实施例包括：
S21：向用户设备发送多个时序参数。
每个时序参数用于指示第一时间单元和第二时间单元之间的时间间隔，第一时间单元为用户设备接收来自于基站的下行传输的时间单元，第二时间单元为用户设备向基站发送下行传输的HARQ反馈信号的时间单元。
本实施例应用于基站侧。具体内容可参考本申请混合自动重传请求反馈方 法第一实施例的描述，在此不再重复。
S22：在至少一个时序参数对应的第二时间单元尝试接收HARQ反馈信号。
通过本实施例的实施，UE可以从多个时序参数中寻找不冲突的时序参数以发送HARQ反馈信号，对应的，基站尝试在多个第二时间单元接收HARQ反馈信号，与现有技术中固定的单个时序参数相比，可以减少HARQ反馈信号因冲突被丢弃的情况，改善PDSCH的性能。
如图11所示，本申请混合自动重传请求反馈方法第三实施例包括：
S31：接收来自于基站的第一时序参数。
第一时序参数用于指示第一时间单元和第二时间单元之间的时间间隔，第一时间单元为用户设备接收来自于基站的下行传输的时间单元，第二时间单元为用户设备向基站发送下行传输的HARQ反馈信号的时间单元。
本实施例应用于用户设备侧。具体内容可参考本申请混合自动重传请求反馈方法第一实施例中的相关描述。
S32：若使用第一时序参数发送HARQ反馈信号出现冲突，则对第一时序参数进行调整得到不冲突的第二时序参数。
若第一时序参数对应的第二时间单元在TDD配置中是下行的，那么用户设备无法在第一时序参数对应的第二时间单元发送HARQ反馈信号，意味着第一时序参数是冲突的，需要进行调整。
如图12所示，S32可以具体包括：
S321：按照预设步长对第一时序参数进行递增或递减调整得到第二时序参数。
参考图6对应的具体实施例的描述，可知对于下行传输来说，从第一个下行slot开始按slot number依次递增，对应的不冲突的k1的值是处于一个递减的状态。为减小调整所需的时间，基站可以配置一个较大的第一时序参数，然后用户设备采用递减的方式进行调整；或者，基站可以配置一个较小的第一时序参数，然后用户设备采用递增的方式进行调整。
调整第一时序参数的过程也可以理解为对第一时序参数的更新，具体调整公式如下：
k1＝k1-i·s,i＝0,1,2,…(1)
k1＝k1+i·s,i＝0,1,2,…(2)
其中，＝表示赋值，＝左边的为本次调整之后的时序参数，＝右边的为本次调 整之后的时序参数，i为调整的次数，s为预设步长。公式(1)为递减调整，公式(2)为递增调整。
预设步长可以为单个时隙或者多个时隙。多个时隙的情况下，预设步长可以为x个时隙，x>1并且是根据SPS周期确定的。
由于SPS PDSCH是周期性传输的，并且基站在配置第一时序参数时，是知道当时TDD的配置，正常情况下第一时序参数对于某些SPS PDSCH而言是不冲突的。基于这个前提，不冲突的第二时序参数与第一时序参数之间的时间间隔有较大可能是SPS周期的整数倍。因此可以根据SPS周期来设定调整的步长，以减小复杂度。此时上面两个公式中的
Figure PCTCN2021070923-appb-000001
Period表示SPS PDSCH的周期，由RRC参数SPS-Config中的Periodicity或PeriodicityExt字段指示，以子帧为单位；μ DL表示下行参数集(Numerology)指示，由高层参数subcarrierSpacing来配置，用于将SPS周期和k1的单位归一化。
S322：判断第二时序参数是否是不冲突的。
若是，则跳转到S323，否则跳转到S324。
S323：停止调整。
当前的第二时序参数为不冲突的第二时序参数，执行后续步骤。最终得到的不冲突的第二时序参数不得小于PDSCH的最小处理时间。
S324：判断是否满足终止条件。
调整不可能无止休的进行下去，因此设置有终止条件。终止条件可以包括第二时序参数达到第一阈值和/或调整次数达到第二阈值。
基站可以为用户设备配置第一阈值。例如对于递减策略，可以由高层配置一个参数Th_m，当k1≤Th_m时即终止筛选，Th_m的最小值可以为0。同样地对于递加策略，也可以对k1的上限进行限制，可以由高层配置一个参数Th_p，当k1≥Th_p时即终止筛选，Th_p的最大值可以为k1的上限值。
若满足，则跳转到S325，否则跳转到S321。
S325：放弃发送HARQ反馈信号。
丢弃HARQ反馈信号。
S33：使用不冲突的第二时序参数发送HARQ反馈信号。
在不冲突的第二时序参数对应的第二时间单元发送HARQ反馈信号。
举例说明，如图13所示，TDD配置为DDDDUDDD。假设UE被配置了在DL#1、3的位置上分别接收相应的SPS PDSCH，配置第一时序参数k1＝6。那么 对于DL#1上传输的SPS PDSCH来说相应的HARQ反馈信号应该在DL#6的位置上发送。此时显然k1＝6是不合适的，那么对k1进行减1操作，则k1＝5，当k1＝5时对应DL#5的位置仍然无法上传HARQ反馈信号，对k1再次进行减1操作，取k1＝4，此时对应UL#1可以进行HARQ反馈信号的传输。同样地，DL#3上的下行传输也使用相同的方式，从k1＝6依次递减，直到k1＝2时可以在UL#1上成功传输HARQ反馈信号。
通过本实施例的实施，UE可以在第一时序参数出现冲突的情况下，尝试对第一时序参数进行调整以寻找不冲突的第二时序参数发送HARQ反馈信号，从而减少HARQ反馈信号因冲突被丢弃的情况，改善PDSCH的性能。
如图14所示，本申请混合自动重传请求反馈方法第四实施例包括：
S41：向用户设备发送第一时序参数。
第一时序参数用于指示第一时间单元和第二时间单元之间的时间间隔，第一时间单元为用户设备接收来自于基站的下行传输的时间单元，第二时间单元为用户设备向基站发送下行传输的HARQ反馈信号的时间单元。
本实施例应用于基站侧。具体内容可参考本申请混合自动重传请求反馈方法第三实施例的描述，在此不再重复。
S42：在第二时序参数对应的第二时间单元尝试接收HARQ反馈信号。
第二时序参数是对第一时序参数进行调整而得到的。
通过本实施例的实施，UE可以在第一时序参数出现冲突的情况下，尝试对第一时序参数进行调整以寻找不冲突的第二时序参数以发送HARQ反馈信号，对应的，基站在在第二时序参数对应的第二时间单元尝试接收HARQ反馈信号，从而减少HARQ反馈信号因冲突被丢弃的情况，改善PDSCH的性能。
