本公开实施例中术语“多个”是指两个或两个以上,其它量词与之类似。
下面将结合本公开实施例中的附图,对本公开实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅仅是本申请一部分实施例,并不是全部的实施例。基于本申请中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都属于本申请保护的范围。
本公开实施例提供一种UCI传输方法、接收方法、终端和网络设备,以解决通信系统的工作效率比较低的问题。
其中,方法和设备是基于同一申请构思的,由于方法和设备解决问题的原理相似,因此装置和方法的实施可以相互参见,重复之处不再赘述。
本公开实施例提供的技术方案可以适用于多种系统,尤其是5G系统。例如适用的系统可以是全球移动通讯(global system of mobile communication,GSM)系统、码分多址(code division multiple access,CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access,WCDMA)通用分组无线业务(general packet radio service,GPRS)系统、长期演进(long term evolution,LTE)系统、LTE频分双工(frequency division duplex,FDD)系统、LTE时分双工(time division duplex,TDD)系统、高级长期演进(long term evolution advanced,LTE-A)系统、通用移动系统(universal mobile telecommunication system,UMTS)、全球互联微波接入(worldwide interoperability for microwave access,WiMAX)系统、5G新空口(New Radio,NR)系统、6G系统等。这多种系统中均包括终端设备和网络设备。系统中还可以包括核心网部分,例如演进的分组系统(Evloved Packet System,EPS)、5G系统(5GS)等。
请参见图1a,图1a是本公开实施可应用的网络构架的结构示意图,如图 1a所示,包括终端11和网络设备12。
其中,本公开实施例涉及的终端,可以是指向用户提供语音和/或数据连通性的设备,具有无线连接功能的手持式设备、或连接到无线调制解调器的其他处理设备等。在不同的系统中,终端设备的名称可能也不相同,例如在5G系统中,终端设备可以称为用户设备(User Equipment,UE)。无线终端设备可以经无线接入网(Radio Access Network,RAN)与一个或多个核心网(Core Network,CN)进行通信,无线终端设备可以是移动终端设备,如移动电话(或称为“蜂窝”电话)和具有移动终端设备的计算机,例如,可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置,它们与无线接入网交换语言和/或数据。例如,个人通信业务(Personal Communication Service,PCS)电话、无绳电话、会话发起协议(Session Initiated Protocol,SIP)话机、无线本地环路(Wireless Local Loop,WLL)站、个人数字助理(Personal Digital Assistant,PDA)等设备。无线终端设备也可以称为系统、订户单元(subscriber unit)、订户站(subscriber station),移动站(mobile station)、移动台(mobile)、远程站(remote station)、接入点(access point)、远程终端设备(remote terminal)、接入终端设备(access terminal)、用户终端设备(user terminal)、用户代理(user agent)、用户装置(user device),本公开实施例中并不限定。
本公开实施例涉及的网络设备,可以是基站,该基站可以包括多个为终端提供服务的小区。根据具体应用场合不同,基站又可以称为接入点,或者可以是接入网中在空中接口上通过一个或多个扇区与无线终端设备通信的设备,或者其它名称。网络设备可用于将收到的空中帧与网际协议(Internet Protocol,IP)分组进行相互更换,作为无线终端设备与接入网的其余部分之间的路由器,其中接入网的其余部分可包括网际协议(IP)通信网络。网络设备还可协调对空中接口的属性管理。例如,本公开实施例涉及的网络设备可以是全球移动通信系统(Global System for Mobile communications,GSM)或码分多址接入(Code Division Multiple Access,CDMA)中的网络设备(Base Transceiver Station,BTS),也可以是带宽码分多址接入(Wide-band Code Division Multiple Access,WCDMA)中的网络设备(NodeB),还可以是长期演进(long term evolution,LTE)系统中的演进型网络设备(evolutional Node  B,eNB或e-NodeB)、5G网络架构(next generation system)中的5G基站(gNB),也可以是家庭演进基站(Home evolved Node B,HeNB)、中继节点(relay node)、家庭基站(femto)、微微基站(pico)等,本公开实施例中并不限定。在一些网络结构中,网络设备可以包括集中单元(centralized unit,CU)节点和分布单元(distributed unit,DU)节点,集中单元和分布单元也可以地理上分开布置。
网络设备与终端之间可以各自使用一或多根天线进行多输入多输出(Multi Input Multi Output,MIMO)传输,MIMO传输可以是单用户MIMO(Single User MIMO,SU-MIMO)或多用户MIMO(Multiple User MIMO,MU-MIMO)。根据根天线组合的形态和数量,MIMO传输可以是2D-MIMO、3D-MIMO、FD-MIMO或massive-MIMO,也可以是分集传输或预编码传输或波束赋形传输等。
无线通信系统中(例如:5G NR,5Generation New RAT)中支持灵活的定时关系。对于PDSCH承载其调度信息的PDCCH指示PDSCH与PDCCH之间的调度定时关系(Scheduling timing,即K0)以及PDSCH到其对应的HARQ-ACK之间的反馈定时关系(HARQ-ACK timing,即K1)。具体地,PDCCH所使用的DCI格式中的时域资源分配指示域指示PDSCH所在时隙与DCI所在时隙的时隙偏移K0;DCI格式中的PDSCH到HARQ-ACK反馈定时指示域指示PDSCH结束到HARQ-ACK开始之间的时隙个数K1,即时隙n中传输的PDSCH在时隙n+K1中进行HARQ-ACK传输,如图1b所示。K1的全集为{0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15},通常会配置给终端最多8个值。在一些协议版本中,K1的值是以时隙(slot)为单位的,即K1=1表示间隔1个时隙。在另一些协议版本6中,K1的值可以是以时隙或者子时隙(sub-slot)为单位,其中子时隙可以预先配置为2个符号长度(即一个时隙中顺序存在7个子时隙),或者7个符号长度(即一个时隙中顺序存在2个子时隙)等。
需要说明的是,本公开实施例中仅是以5G NR系统进行举例说明,本公开实施例并不限定应用于5G NR系统,例如:也可以应用于6G系统等。
本公开实施例中,UCI可以包含HARQ-ACK、CS、SR等信息。其中, HARQ-ACK是肯定确认(ACK,ACKnowledgment)和否定确认(NACK,Non-ACKnowledgment)的统称,用于针对PDSCH或指示半持续调度(SPS,Semi-Persistent Scheduling)资源释放的PDCCH(又称SPS PDSCH release)进行反馈,告知网络设备PDSCH或指示SPS PDSCH释放的PDCCH是否正确接收;CSI用于反馈下行信道质量,从而帮助网络设备更好的进行下行调度,例如根据CSI进行调制编码方式(MCS,Modulation and Coding Scheme)选择、配置适当的RB资源等;SR用于当终端有上行业务需要传输时,向网络设备请求携带上行业务的PUSCH的传输资源。
UCI可以在PUCCH上传输。其中,HARQ-ACK是可以按照上述DCI中通知的K1或者在DCI中不包含指示K1的指示域时根据高层信令预先配置的K1值确定在哪个时隙或子时隙中的哪些符号上传输的(其中PUCCH的具体符号位置是通过DCI中的PUCCH资源指示域所指示的PUCCH资源中的相关参数得到的);特别的,对于传输SPS PDSCH的HARQ-ACK的PUCCH资源是根据高层信令预先为SPS PDSCH配置的PUCCH资源获得的;对于周期CSI和SR,其传输的PUCCH资源是高层信令预先配置的,其传输的机会是根据高层信令预先配置的周期和偏移值确定的固定的时隙中的固定的符号位置。当承载UCI的PUCCH与PUSCH在时域上存在冲突时(例如时域上重叠,可能在同一个载波,也可能在不同的载波),在满足特定条件(如复用传输的时间条件等)时,可以将PUCCH上的UCI转移到PUSCH上传输,从而不再传输PUCCH,以避免出现PUCCH和PUSCH的同时传输。因此,则一些情况下,PUSCH也可以承载UCI传输。
5G NR系统中支持半静态(semi-static)和动态(dynamic)两种HARQ-ACK码本(codebook)产生方式。所谓HARQ-ACK codebook即针对在同一个时域位置或上行信道上进行HARQ-ACK反馈的下行传输产生的HARQ-ACK反馈序列。
Dynamic HARQ-ACK codebook可以是根据DL DCI(即调度下行传输的DCI)中的累计下行分配索引(C-DAI,Counter-Downlink Assignment Index)域的指示来进行HARQ-ACK排序、并根据总计DAI(T-DAI,Total-DAI)域来确定HARQ-ACK codebook的总比特数的。因此,可以在不同的反馈时刻 根据实际的调度来调整HARQ-ACK codebook的大小,实现动态的改变codebook大小,从而节省HARQ-ACK反馈开销,但需要保证最后一个调度时刻上不能出现多个载波上同时丢包的情况,如果最后一个时刻的DCI整体丢包,则终端无法获知正确的T-DAI。具体的,首选需要根据K1、K0以及配置的重复传输次数(如果配置了),确定一个载波上的激活带宽部分(BWP,Band Width Part)对应的PDCCH检测机会(MO,monitoring occasion)。如图1c所示,此处简单起见,假设不进行重复传输,即可以根据n-K1找到一个下行传输机会,进而根据这个下行传输机会的调度关系(K0)找到对应的PDCCH MO,如果重复次数大于1,则重复传输的PDSCH的K0基于PDSCH重复传输所占用的多个时隙中的第一个时隙确定,重复传输的PDSCH的K1基于PDSCH重复传输所占用的多个时隙中的最后一个时隙确定,意味着以下行时隙n-K1到n-K1-N中的N个时隙为PDSCH重复传输的一组时隙,对于该组时隙,其基于K0确定的PDCCH MO为时隙n-K1-N对应的PDCCH MO,假定K0总是为0(实际K0可以是多个值,如果为多个值,则对应n-K1的一个下行时隙可以确定多个PDCCH MO),每个时隙中也可以包含多个PDCCH MO。在载波聚合的情况下,基于每个载波对应的PDCCH MO得到所有载波的PDCCH MO全集,其中,不同载波上的PDCCH MO可能是在时间上不对齐的,则按照先时间(时间前后顺序)后频域(即载波编号从小到大)的方式进行排序。终端在确定的PDCCH MO集合中检测使用某种DCI格式(例如格式1-0、格式1-1、格式1-2中的一种或多种)的PDCCH,并根据接收到的PDCCH中的DAI信息(包括C-DAI和T-DAI)产生HARQ-ACK codebook。C-DAI按照先频域后时域的顺序指示到当前载波上当前PDCCH MO已经传输的PDSCH或者指示SPS PDSCH释放的PDCCH的累计个数。T-DAI指示到当前PDCCH MO总计在所有载波上传输的PDSCH或者指示SPS PDSCH释放的PDCCH的个数。多个载波上时域对齐的PDCCH MO中的DCI中的T-DAI相同,具体如图1d所示。
Semi-static HARQ-ACK codebook可以是基于配置给传输PUCCH的载波的K1集合确定的,codebook的大小是不随着实际调度了多少下行传输而发生变化的,因此不会受DCI丢包的影响,传输比较稳定。具体的,根据K1集 合确定每个载波c上(具体的是这个载波上当前激活的BWP上)对应在一个slot或sub-slot n中进行HARQ-ACK反馈的下行传输的位置集合Mc,然后根据Mc即可以确定时隙或子时隙n中传输的HARQ-ACK codebook。以PUCCH基于时隙传输为例,对于每个载波c,根据K1集合中的每个K1值,确定对应在slot n进行HARQ-ACK反馈的时隙集合D;在这个时隙集合中的每个时隙中,进一步根据预先配置的下行时域资源分配信息(TDRA表格或集合,表格中的每一行表示了一种时域调度情况,可以给出起始符号、符号个数、调度时序(即PDCCH与被调度的PDSCH之间的时隙间隔数K0)等信息)中的各种时域位置(一个时域位置可以称为一个起始和长度指示(SLIV,Start and length indicator value),表达了一个起始符号和传输符号个数的组合),确定一个时隙中可以存在的下行传输机会(即能够用于PDSCH传输的位置)的个数;如果终端不支持在一个时隙中接收超过一个单播(unicast)PDSCH,则确定一个时隙对应1个下行传输机会;如果终端支持在一个时隙中接收超过一个unicast PDSCH,则可以根据TDRA表格中的SLIV集合,按照预定规则进行SLIV分组,例如找到第一个结束位置最早的SLIV,以这个SLIV为基准,找到所有起始位置在这个SLIV的结束位置之前的SLIV,将这些SLIV作为一组,对应一个可能的下行传输机会(这是因为重叠的SLIV仅仅是为了提供调度的灵活性,实际调度中只能从中选择一个SLIV使用),然后在SLIV集合中去掉这些SLIV,对剩余SLIV重复上述步骤,直到处理完TDRA表格中包含的所有SLIV,得到多个下行传输机会,如图1e所示,得到的结果是元素A/B/C为一组,对应一个下行传输位置,元素D/E为一组,对应一个下行传输机会,一共得到2个下行传输机会;进一步,在确定下行传输机会的个数之前,如果配置了半静态的上下行时隙结构,每个时隙中可以根据SLIV是否与上行符号冲突来去掉一些不能被使用的SLIV(即无效SLIV),例如SLIV包含的符号集合中存在上行符号,由于存在上下行资源冲突,该下行传输实际不会发生,因此该SLIV可以从SLIV集合去掉,如果一个时隙中所有SLIV对应的符号集合都存在与上行符号的冲突,则这个时隙中不会存在任何下行传输,从而这个时隙不包含下行传输机会;如果PDSCH被配置了重复传输,则一个SLIV只要在重复传输的多个时隙中的某一个时隙中是可用的,则 这个SLIV就需要保留,即只有一个SLIV在重复传输的多个时隙中的每一个时隙中都是与上行符号冲突的,这个SLIV才会被去掉;按照上述方式,可以得到载波c对应下行传输机会的集合Mc,Mc是时隙集合D中的每个时隙中按照上述方式确定的下行传输机会按照顺序构成的,根据Mc确定载波c在slot n中的HARQ-ACK codebook,包括codebook的大小和HARQ-ACK具体内容和顺序;当配置了载波聚合时,按照载波编号顺序(例如从小到大)将每个载波对应的HARQ-ACK codebook级联在一起,得到最终UE要在slot n中传输的HARQ-ACK codebook。具体的,以一个载波以及一个时隙中仅支持一个unicast PDSCH传输为例,假设K1集合为{2,3,4,5,6,7,8,9},则确定对应在时隙n+9反馈HARQ-ACK的Mc集合如图1f所示,其中,根据K1=5和6确定的时隙为半静态配置的UL时隙,不会存在下行传输,因此这两个时隙中没有下行传输机会,不需要在HARQ-ACK codebook中预留HARQ-ACK位置,从而降低HARQ-ACK codebook的冗余信息。
需要说明的是,上述仅是对本公开实施例采用的特征进行举例说明,对于本公开实施例保护的方案不作任何限定。
请参见图2,图2是本公开实施例提供的一种UCI传输方法的流程图,如图2所示,包括以下步骤:

例如,简单起见称上述与第一PDCCH相关联的时间单元(即第一PDCCH所调度的上行信道传输所在的时间单元,第一PDCCH传输所在的时间单元,第一PDCCH所调度的下行共享信道传输所在的时间单元)为第三时间单元,当第三时间单元的定义(时间单位)与偏移值的单位相同时,按照如下方式确定第一时间单元:
1)如果第三时间单元和偏移值的单位都是时隙,则假设第三时间单元为时隙n,偏移值为k,则确定时隙n-k为第一时间单元;如果还允许第一时间单元的单位与偏移值不同,则当第一时间单元的单位为时隙时,确定时隙n-k为第一时间单元,当第一时间单元的单位为子时隙时,将时隙n-k中的所有子时隙都确定为第一时间单元,或者将时隙n-k中的某一个特定的子时隙确定为第一时间单元(例如第一个子时隙或者最后一个子时隙);
2)如果第三时间单元和偏移值的单位都是子时隙,则假设第三时间单元为子时隙n,偏移值为k,则确定子时隙n-k为第一时间单元;如果还允许第一时间单元的单位与偏移值不同,则当第一时间单元的单位为子时隙时,确定子时隙n-k为第一时间单元,当第一时间单元的单位为时隙时,将包含子时隙n-k的时隙m确定为第一时间单元。
当第三时间单元的定义(时间单位)与偏移值不同时,按照如下方式确定第一时间单元:
3)如果第三时间单元的单位是时隙,偏移值的单位是子时隙,假设第三时间单元为时隙n,偏移值为k,则以这个时隙n的起点为基准,向前找k个子时隙(或者把k个子时隙转化为k'个时隙),得到时隙n-k',将时隙n-k'中的所有子时隙都确定为第一时间单元,或者将时隙n-k'中的某一个特定的子时隙确定为第一时间单元(例如第一个子时隙或者最后一个子时隙);如果还允许第一时间单元的单位与偏移值不同,则当第一时间单元的单位为子时隙时,同上,当第一时间单元的单位为时隙时,确定时隙n-k'为第一时间单元;
4)如果第三时间单元的单位是子时隙,偏移值的单位是时隙,假设第三时间单元为子时隙n,偏移值为k,则以这个子时隙n所在的时隙(n')的起点为基准,向前找k个时隙,得到时隙n'-k,将时隙n'-k确定为第一时间单 元,或者,将偏移值k转换为子时隙为单位的k',以子时隙n的起点为基准,向前找k'个子时隙,得到子时隙n-k',将包含子时隙n-k'的时隙m确定为第一时间单元;如果还允许第一时间单元的单位与偏移值不同,则当第一时间单元的单位为时隙时,同上,当第一时间单元的单位为子时隙时,将时隙n'-k中的所有子时隙都确定为第一时间单元,或者将时隙n'-k中的某一个特定的子时隙确定为第一时间单元(例如第一个子时隙或者最后一个子时隙),或者,将子时隙n-k'确定为第一时间单元。
可选的,所述偏移值的时间单位按照下述方式之一确定:
所述偏移值的时间单位以所述第一时间单元的定义为基准;或者,
所述偏移值的时间单位以所述第二时间单元的定义为基准;或者,
在所述第一时间单元的定义与所述第二时间单元的定义不同的情况下,所述偏移值的时间单位以所述第一时间单元和所述第二时间单元中时间长度较长的时间单元的定义为基准;或者,
在所述第一时间单元的定义与所述第二时间单元的定义不同的情况下,所述偏移值的时间单位以所述第一时间单元和所述第二时间单元中时间长度较短的时间单元的定义为基准;或者,
所述偏移值的时间单位以所述第一时间单元和所述第二时间单元的定义为基准,或以所述第一时间单元和所述第二时间单元中的任意一个的定义为基准,其中,约定或者配置所述第一时间单元的定义与所述第二时间单元的定义相同。
上述偏移值的时间单位以所述第一时间单元的定义为基准可以是,在第一时间单元的定义与第二时间单元的定义不同的情况下,上述偏移值的时间单位以第一时间单元的定义为基准。例如:第二时间单元的定义(时间单位)是时隙,即一个第二时间单元是一个时隙,第一时间单元的定义(时间单位)是子时隙,即一个第一时间单元是一个子时隙,则偏移值以子时隙为单位。
或者,上述偏移值的时间单位以所述第一时间单元的定义为基准可以是,在第一时间单元的定义与第二时间单元的定义相同的情况下,上述偏移值的时间单位以第一时间单元和第二时间单元中的任何一个的定义为基准。也就是说,该情况下,由于二者定义相同,从而不管第一时间单元和第二时间单 元的定义是否相同,都以第一时间单元的定义为基准。例如:第二时间单元和第一时间单元的定义均是时隙,则偏移值以时隙为单位。
上述所述偏移值的时间单位以所述第二时间单元的定义为基准可以是,在第一时间单元的定义与第二时间单元的定义不同的情况下,上述偏移值的时间单位以第二时间单元的定义为基准;例如:第二时间单元的定义(时间单位)是时隙,即一个第二时间单元是一个时隙,第一时间单元的定义(时间单位)是子时隙,即一个第一时间单元是一个子时隙,则偏移值以时隙为单位。
或者,上述偏移值的时间单位以所述第二时间单元的定义为基准可以是,在第一时间单元的定义与第二时间单元的定义相同的情况下,上述偏移值的时间单位以第一时间单元和第二时间单元中的任何一个的定义为基准。也就是说,该情况下,由于二者定义相同,从而不管第一时间单元和第二时间单元的定义是否相同,都以第二时间单元的定义为基准。例如:第二时间单元和第一时间单元的定义均是时隙,则偏移值以时隙为单位。
上述在所述第一时间单元的定义与所述第二时间单元的定义不同的情况下,所述偏移值的时间单位以所述第一时间单元和所述第二时间单元中时间长度较长的时间单元的定义为基准可以实现:以第一时间单元和第二时间单元中时间长度较长的时间单元的定义作为上述偏移值的基准。例如:第一时间单元的定义以时隙为单位,即一个第一时间单元是一个时隙,而第二时间单元的定义以子时隙为单位,即一个第二时间单元是一个子时隙,则偏移值的单位为时隙。
在所述第一时间单元的定义与所述第二时间单元的定义不同的情况下,所述偏移值的时间单位以所述第一时间单元和所述第二时间单元中时间长度较短的时间单元的定义为基准可以实现:以第一时间单元和第二时间单元中时间长度较短的时间单元的定义作为上述偏移值的基准。例如:第一时间单元的定义以时隙为单位,即一个第一时间单元是一个时隙,而第二时间单元的定义以子时隙为单位,即一个第二时间单元是一个子时隙,则偏移值的单位为子时隙。
上述偏移值的时间单位以所述第一时间单元和所述第二时间单元的定义 为基准,或以所述第一时间单元和所述第二时间单元中的任意一个的定义为基准可以是:在约定或者配置所述第一时间单元的定义与所述第二时间单元的定义相同的情况下,以第一时间单元和第二时间单元的定义为基准,或以第一时间单元和第二时间单元中的任意一个的定义为基准。例如:预先约定或者预先配置第一时间单元和第二单元的定义均为子时隙,这样可以实现被丢弃的第一UCI如果是使用基于子时隙的传输,则进行第一UCI重新传输时也基于子时隙进行传输,而不是在基于时隙的PUCCH中进行重新传输。
作为一种可选的实施方式,所述重传指示信息包括K比特,每个比特对应一个预定义的时间段中的一个子时间段,其中,所述第一时间单元包括所述K比特中取值为第一值的比特对应的子时间段中包含的时间单元,K为大于或者等于1的整数,一个子时间段中包含至少一个时间单元。
其中,当一个子时间段就是一个时间单元时,所述重传指示信息包括K比特,每个比特对应一个预定义的时间段中的一个时间单元,其中,所述第一时间单元包括所述K比特中取值为第一值的比特对应的时间单元,K为大于或者等于1的整数。
其中,一个预定的时间段包含K个子时间段或者包含K个时间单元。
上述每个比特对应一个预定义的时间段中的一个子时间段可以是:上述K比特与上述预定义的时间段中的子时间段是一一对应关系,这样通过上述K比特可以准确地第一时间单元。
其中,上述第一值可以协议定义或者网络侧配置的,如1或者0。
该实施方式中,可以实现将第一值的比特对应的子时间段中包含的时间单元确定为上述第一时间单元,而忽略第二值的比特对应子时间段(即认为第二值的比特对应的子时间段中的时间单元中都不存在第一UCI需要重新传输),该第二值为与上述第一值不同的值,如第一值为1,则第二值为0。如果一个子时间段包含多个时间单元,则对应第一值的子时间段中的多个时间单元都被确定为第一时间单元,如果一个子时间段仅包含一个时间单元,则对应第一值的子时间段就是一个时间单元,可以实现将第一值的比特对应的时间单元确定为上述第一时间单元。
以1为上述第一值举例,上述K比特中的每一比特对应一个预定义时间 段中的一个子时间段,1比特置为“1”表示对应的子时间段中包含的时间单元为第一时间单元,1比特置为“0”表示对应的子时间段中包含的时间单元不需要进行UCI重传。
可选的,上述预定义时间段包括如下之一:
包含所述第一PDCCH传输在内的预定义时间段;
在所述第一PDCCH传输之前的预定义时间段;
包含所述第一PDCCH所调度的上行传输在内的预定义时间段;
在所述第一PDCCH所调度的上行传输之前的预定义时间段。
上述在所述第一PDCCH传输之前的预定义时间段可以是,在包含所述第一PDCCH传输在内的预定义时间段之前的一个预定义时间段。
本公开实施例中,预定义时间段可以是协议预先定义或者网络侧预先配置的上述一种定义方式下的时间段。
上述上行传输可以是PUCCH或PUSCH传输。例如:如果上述上行传输是PUCCH,则第一PDCCH本身的HARQ-ACK或者第一PDCCH所调度的PDSCH的HARQ-ACK需要在这个PUCCH上传输,则这个PUCCH可以称之为第一PDCCH所调度的上行传输;如果上述上行传输是PUSCH,则第一PDCCH调度这个PUSCH传输,PUSCH称之为第一PDCCH所调度的上行传输。
重传指示域对应的预定义时间段可以是:包含所述PDCCH传输在内的一个预定时间段或包含PDCCH传输在内的一个预定义时间段之前的一个预定义时间段,或者包含所述PDCCH所调度的上行传输在内的一个预定时间段,或者包含所述PDCCH所调度的上行传输在内的一个预定时间段之前的一个预定义时间段。
例如:预定义时间段为一个无线帧,以15kHz子载波间隔为例,1个时隙为一个子时间段,则时间段中包含10个子时间段,K=10比特,每1比特对应一个时隙,如果上述第一PDCCH在无线帧#2中传输,第一PDCCH中的K=10比特指示域指示的是无线帧#2中的10个时隙中哪个或哪些时隙是第一时间单元,即这些时隙中存在UCI被丢弃需要进行重传。
可选的,所述每个比特对应的时间单元的时间单位或所述每个比特对应 的子时间段的时间单位按照下述方式之一确定:
所述每个比特对应的时间单元的时间单位或所述每个比特对应的子时间段的时间单位以所述第一时间单元的定义为基准;或者,
所述每个比特对应的时间单元的时间单位或所述每个比特对应的子时间段的时间单位以所述第二时间单元的定义为基准;或者,
在所述第一时间单元的定义与所述第二时间单元的定义不同的情况下,所述每个比特对应的时间单元的时间单位或所述每个比特对应的子时间段的时间单位以所述第一时间单元和所述第二时间单元中时间长度较长的时间单元的定义为基准;或者,
当所述在所述第一时间单元的定义与所述第二时间单元的定义不同的情况下,所述每个比特对应的时间单元的时间单位或所述每个比特对应的子时间段的时间单位以所述第一时间单元和所述第二时间单元中时间长度较短的时间单元的定义为基准;或者,
所述每个比特对应的时间单元的时间单位或所述每个比特对应的子时间段的时间单位以所述第一时间单元和所述第二时间单元的定义为基准,或以所述第一时间单元和所述第二时间单元中的任意一个的定义为基准,其中,约定或者配置所述第一时间单元的定义与所述第二时间单元的定义相同。
其中,上述每个比特对应的时间单元的时间单位或所述每个比特对应的子时间段的时间单位可以参见以上述偏移值的时间单位的相应说明,例如:第二时间单元的定义是时隙,第一时间单元的定义是子时隙,则如果约定第一时间单元为基准,则每个比特对应的时间单元的时间单位或所述每个比特对应的子时间段的时间单位以子时隙为单位。
作为一种可选的实施方式,上述第一UCI被丢弃UCI的原因包括如下至少一项:
承载UCI的上行信道与其他信道之间冲突,所述其他信道的优先级高于所述承载UCI的上行信道;
在所述终端配置有上行取消的情况下,承载UCI的上行信道的传输资源全部或者部分包含在上行取消指示信令(CI,cancellation indication)所通知停止或取消的上行区域中;
承载UCI的上行信道所包含的符号集合中存在高层信令配置的下行符号或同步信号块(SSB,Synchronization Signals Block)占用的符号;
承载UCI的上行信道所包含的符号集合中包含了高层信令配置的灵活符号,且所述灵活符号(Flexible)上存在由PDCCH调度的下行传输,或者,在所述终端配置有检测指示时隙结构的DCI时,所述灵活符号被指示时隙结构的DCI中的指示信息指示为下行符号;
承载UCI的上行信道所包含的符号集合中包含了高层信令配置的灵活符号,且在所述终端配置有检测指示时隙结构的DCI,但所述终端未收到指示时隙结构的DCI;
承载UCI的PUSCH在所述终端执行上行跳过(UL skipping)的区域内;
承载UCI的配置授权(CG,Configured Grant)PUSCH由于被其他具有DCI调度的PUSCH导致所停止或取消。
其中,上述承载UCI的上行信道与其他信道之间冲突可以是,承载UCI的上行信道与高优先级的信道在时域上存在重叠,导致低优先级的承载UCI的上行信道被丢弃。
上述上行取消指示信令可以通过DCI传输,例如:通过DCI格式2-4传输。例如:上述上行取消指示信通知一部分上行区域中接收到CI的终端需要停止上行传输,让出资源给更高优先级的其他终端的业务传输,从而丢弃UCI。
上述PDCCH调度的下行传输可以包括如下至少一项:
PDSCH、指示SPS资源释放的PDCCH(又称SPS PDSCH release)、信道状态信息参考信号(CSI-RS,Channel State Information-Reference Signaling)等传输。
上述指示时隙结构的DCI可以是用于承载时隙格式指示信息(SFI,Slot Format Indication)的DCI,如DCI格式2-0。
作为一种可选的实施方式,在所述终端接收到多个第一PDCCH,且所述多个第一PDCCH所调度的PDSCH或所指示的半持续物理下行共享信道释放(SPS PDSCH release)的混合自动重传请求确认(HARQ-ACK)在所述第二时间单元内反馈的情况下:
所述多个第一PDCCH的重传指示信息所指示的偏移值相同;或者
所述多个第一PDCCH的重传指示信息所指示的偏移值不同,且基于所述多个第一PDCCH中的每一个或最后一个第一PDCCH中的重传指示域来确定所述第一时间单元。
其中,上述多个第一PDCCH的重传指示信息所指示的偏移值相同可以是,这多个第一PDCCH中任一PDCCH均指示上述第一时间单元,从而可以终端重传UCI的可靠性,例如,即丢失一个PDCCH,还可以从其他PDCCH中获取重传指示信息。其中,上述多个第一PDCCH的重传指示信息所指示的偏移值不同可以是,这多个第一PDCCH中至少2个第一PDCCH指示的上述第一时间单元是不同的,从而可以允许网络设备根据实时需求改变后续第一PDCCH中的重传指示信息,如果所有第一PDCCH中的重传指示信息都有效,则根据所有第一PDCCH中的重传指示信息确定第一时间单元,可以指示更多的第一时间单元中的第一UCI进行重传,或者,如果以最后的第一PDCCH中的重传指示信息为基准,则可以允许后面的重传指示信息覆盖前面的重传指示信息,即允许网络设备更新前面的指示(比如仅允许一个第一时间单元中的第一UCI进行重传,而当已经在前面的第一PDCCH中指示了一个第一时间单元A之后,又发现还存在另一个第一时间单元B中的第一UCI被丢弃,而这个第一时间单元B中的第一UCI较第一时间单元A中的第一UCI更为重要,则网络设备可以通过更改后续的第一PDCCH中的重传指示信息用来指示第一时间单元B,实现让终端优先对第一时间单元B中的第一UCI进行重传)。
作为一种可选的实施方式,在所述第一PDCCH中包括优先级指示域的情况下,所述第一UCI的优先级与所述优先级指示域所指示的优先级相同或者不同或者所述第一UCI的优先级大于等于所述优先级指示域所指示的优先级;或者
在所述第一PDCCH中不包括优先级指示域的情况下,所述第一UCI的优先级与所述第一PDCCH所使用的DCI对应的预定义优先级相同或者不同或者所述第一UCI的优先级大于等于所述第一PDCCH所使用的DCI对应的预定义优先级。
该实施方式中,若所述第一UCI的优先级与所述优先级指示域所指示的 优先级相同,则可以实现相同优先级的UCI进行复用传输,当若所述第一UCI的优先级与所述优先级指示域所指示的优先级不同,则可以实现不同优先级的UCI可以复用传输。
上述DCI对应的预定义优先级可以是,预先为该DCI约定或者配置的优先级;例如可能不同的DCI格式预先约定或配置的默认优先级是不同的,当然也可能相同。
作为一种可选的实施方式,所述终端在第二时间单元中传输第一UCI,包括:
所述第一UCI按照在所述第一时间单元中产生的大小和比特,在所述第二时间单元中进行传输。
上述大小可以是第一UCI的比特数,而上述比特可以是第一UCI的比特内容。
其中,上述第一UCI在所述第一时间单元中产生的大小和比特可以参见本公开实施例前面描述的半静态(semi-static)和动态(dynamic)HARQ-ACK码本的大小和比特确定方式,当然,对此不作限定,例如:也可以采用协议后续新定义的方式产生。
上述第一UCI按照在所述第一时间单元中产生的大小和比特,在所述第二时间单元中进行传输可以是,第一UCI在第二时间单元内传输的序列与在第一时间单元内原本需要传输但被丢弃的序列是一模一样的。

或者,
当所述第一PDCCH调度PUSCH在第二时间单元中传输时,在所述第二时间单元中的所述PUSCH资源上传输所述第一UCI。
其中,上述在所述第二时间单元内所述终端不传输其他UCI可以是,在第二时间单元内不包含其他UCI。
上述PUCCH资源根据所述第一UCI在所述第一时间单元对应的PUCCH资源编号确定可以是,在第二时间单元中选取与第一时间单元中第一UCI原本传输对应的PUCCH资源编号相同的PUCCH资源,并在该PUCCH资源上传输第一UCI。
可选的,
在所述第一时间单元包括多个时间单元的情况下,所述终端按照下述方式中的一种在第二时间单元中传输第一UCI:
在所述多个时间单元中被丢弃的多个第一UCI按照预定级联顺序级联在一起,在第二时间单元中的PUCCH资源上传输级联后的第一UCI;其中,所述PUCCH资源根据所述多个时间单元中一个目标时间单元中的第一UCI在所述目标时间单元中对应的PUCCH资源编号确定,所述目标时间单元为所述多个时间单元中的第一个时间单元或最后一个时间单元或其中的第一UCI对应的PUCCH资源的容量最大的时间单元;或者,所述PUCCH资源根据级联后的第一UCI的比特数和所述第一PDCCH中的PUCCH资源指示域确定;或者,所述PUCCH资源为高层信令预先配置的资源;其中,预定级联顺序包括时间单元的先后顺序、UCI种类的顺序中的至少一种;
或者,
在第二时间单元中的多个PUCCH资源上独立传输在所述多个时间单元中被丢弃的多个第一UCI,其中,多个PUCCH资源分别根据多个第一UCI在各自对应的第一时间单元中对应的PUCCH资源编号确定定。
该实施方式中,可以实现根据多个时间单元中的第一个、最后一个或者PUCCH资源的容量最大的时间单元确定PUCCH资源,或者可以实现根据第一UCI的比特数和所述第一PDCCH中的PUCCH资源指示域确定PUCCH资源。
其中,上述预定级联顺序可以包括时间单元的先后顺序、UCI种类的顺 序中的至少一种。例如:第一时间单元的定义是时隙,如第一个时隙中UCI为HARQ-ACK,第二个时隙中的UCI为CSI,第三个时隙中的UCI为HARQ-ACK,则可以按照是第一个时隙的HARQ-ACK,第二个时隙的CSI,第三个时隙的HARQ-ACK的顺序级联,或者,也可以按照UCI种类排列。或者上述两种的结合,例如:先按照UCI种类排列,当同一种UCI如果存在多个,则按照时间顺序排列,则为第一个时隙的HARQ-ACK,第三个时隙的HARQ-ACK,第二个时隙的CSI。当然,也可以是先按照时间顺序,再按照UCI种类顺序。
上述在第二时间单元中的多个PUCCH资源上独立传输在所述多个时间单元中被丢弃的多个第一UCI可以是,多个第一UCI分别按照各自对应的第一时间单元对应的PUCCH资源上传输。且这里的多个第一UCI对应的第一时间单元对应的PUCCH资源可以不重叠。
作为一种可选的实施方式,在所述第二时间单元内所述终端传输第二UCI的情况下:所述终端在第二时间单元中传输第一UCI,包括:

确定所述第一UCI对应的第一PUCCH资源,以及所述第二UCI对应的第二PUCCH资源,当所述第一PUCCH资源与所述第二PUCCH资源在时域上不重叠时,在第一PUCCH资源传输所述第一UCI,在第二PUCCH资源传输所述第二UCI,当所述第一PUCCH资源与所述第二PUCCH资源在时域上重叠时,在同一个PUCCH资源上复用传输所述第一UCI和所述第二UCI,其中,所述第一PUCCH资源根据所述第一UCI的比特数和所述第一PDCCH中的PUCCH资源指示域确定,或者,所述第一PUCCH资源根据所述第一UCI在所述第一时间单元中对应的PUCCH资源编号确定,或者,所述第一PUCCH资源为高层信令预先配置的资源。
其中,当所述第一PUCCH资源与所述第二PUCCH资源在时域上重叠时,在同一个PUCCH资源上复用传输所述第一UCI和所述第二UCI,这个PUCCH资源可以根据协议中定义的UCI复用传输的规则确定的。
其中,根据所述第一UCI在所述第一时间单元中对应的PUCCH资源编号确定PUCCH资源可以是:在第二时间单元中,取与第一时间单元中第一UCI原本传输对应的PUCCH资源编号相同的PUCCH资源,作为在第二时间单元中传输的PUCCH资源。

作为一种可选的实施方式,所述第一UCI包括如下至少一项:
HARQ-ACK、CSI、SR。
作为一种可选的实施方式,所述第一UCI为所述终端在所述第一时间单 元内丢弃的全部或者部分UCI。
例如:当第一UCI为全部UCI时,第一时间单元中存在HARQ-ACK和SR被丢弃了,则重新传输原本要在第一时间单元中传输的HARQ-ACK和SR;又例如,当第一UCI为部分UCI时,预先约定或配置的其中一种或几种被丢弃的UCI进行重新传输,其他UCI则不进行重新传输,例如约定或配置为在第一时间单元中被丢弃的HARQ-ACK进行重新传输,而第一时间单元中如果还存在CSI和/或SR也被丢弃了,则不需要重新传输(因为SR、CSI是周期性传输的,可以在下一个周期机会中自行传输)。
上述实施方式,可以提高UCI重传的灵活性。
作为一种可选的实施方式,在所述终端判断所述终端支持或者配置有UCI重输的情况下,确定所述第一PDCCH包括所述重传指示信息。
上述在所述终端判断所述终端支持或者配置有UCI重输的情况下,确定所述第一PDCCH包括所述重传指示信息可以是,在终端支持或者配置有UCI重输的情况下,才确定上述第一PDCCH包括上述重传指示信息,并按照本公开实施例提供的UCI传输方法进行相应的重传;对于没有配置或者不支持UCI重传的终端,其PDCCH中可以不包含重传指示信息,也不需要按照本公开方案确定第一时间单元并重传第一UCI。
本公开实施例中,终端接收第一物理上行控制信道PDCCH,所述第一PDCCH包括重传指示信息;所述终端依据所述重传指示信息确定第一时间单元;所述终端在第二时间单元中传输第一UCI,其中,所述第一UCI为在所述第一时间单元中被丢弃的UCI,其中,所述第二时间单元为所述第一PDCCH对应的上行信道传输所在的时间单元。这样可以实现对第一UCI的重传,从而避免第一UCI丢弃导致的网络设备不能及时获得UCI信息带来的诸如不必要的下行重传(例如HARQ-ACK被丢弃的情况)、非最优的调度(例如CSI被丢弃的情况)、不能及时进行上行调度(例如SR被丢弃的情况)等问题,提高通信系统的工作效率。

需要说明的是,本实施例作为与图2所示的实施例中对应的网络设备的实施方式,其具体的实施方式可以参见图2所示的实施例的相关说明,为了避免重复说明,本实施例不再赘述,且还可以达到相同有益效果。
下面通过多个实施例中对本公开实施例提供的方法进行举例说明:
实施例1:
该实施例以使用半静态码本传输为例进行举例说明,可以包括如下:
假设终端被配置了1个载波,使用半静态码本传输,且PDSCH结束到HARQ-ACK开始之间的时隙个数K1={1,2,3,4},以基于时隙的PUCCH传输为例,假设根据半静态码本的确定方式确定时隙4中的半静态HARQ-ACK码本的大小为3比特HARQ-ACK,对应了时隙0、1、2中的PDSCH的HARQ-ACK,其中时隙3为上行时隙,不包含在时隙4的半静态码本范围中,确定时隙9中的半静态HARQ-ACK码本的大小为4比特HARQ-ACK,对应了时隙5、6、7、8中的PDSCH的HARQ-ACK。假设在时隙4中,由于在PUCCH资源1上传输的HARQ-ACK是增强型移动宽带(eMBB,Enhance Mobile Broadband)业务的HARQ-ACK,优先级比较低,而时隙4中还存在一个承载高可靠低时延通信(URLLC,Ultra Reliable Low Latency Communications)业务的PUSCH与PUCCH资源1冲突,则时隙4中的PUCCH资源1被丢弃,如图4所示,3比特HARQ-ACK的第一UCI被丢弃。
针对上述场景,网络设备的行为可以包括如下:
确定时隙4中因为其调度了一个承载URLLC的PUSCH导致了PUCCH资源1上的第一UCI(eMBB HARQ-ACK)被丢弃,为了提供这些第一UCI的重新传输机会,网络设备在确定了存在这种丢弃行为之后,通过某个或某些时隙中的第一PDCCH中设置重传指示信息,来指示在后续时隙中进行时隙4中的第一UCI的重传,例如如图5所示,具体可以如下包括如下方式:
方式一:网络设备可以在时隙5、6、7、8中的每个时隙中调度PDSCH传输的第一PDCCH中都将重传指示信息设置为指示时隙4为第一时间单元的指示状态,当然,网络设备也可以仅在时隙8中的第一PDCCH中将重传指示信息设置为指示时隙4为第一时间单元的指示状态。其中,在方式一中,重传指示信息可以包括如下指示方式:
方式1:重传指示信息指示偏移值,指示状态如表1或表2所示,偏移值以时隙为单位,假设以第一PDCCH所对应的上行传输(可以是第一PDCCH所调度的PUSCH传输所在的时隙,即根据第一PDCCH中调度PUSCH的时序K2确定的,或者第一PDCCH自身的HARQ-ACK通过PUCCH传输所在的时隙或第一PDCCH所调度的PDSCH的HARQ-ACK通过PUCCH传输所 在的时隙,即根据第一PDCCH中的K1或高层配置的一个K1确定)所在的时隙(即第二时间单元)为参考确定第一时间单元(当然以其他方式,如第一PDCCH自身所在的时隙或第一PDCCH所调度的PDSCH所在的时隙为参考的方式来确定也是可以的,不再赘述)。例如:时隙5、5、6、7中的第一PDCCH中的K1指示域分别为4、3、2、1,都确定在时隙9中通过PUCCH进行HARQ-ACK传输,即第二时间单元为时隙9,以时隙9为参考,要指示时隙4中的HARQ-ACK在时隙9中进行重传,则需要设置重传指示信息指示的偏移值为5个时隙,例如基于表格1,则当重传指示域为2比特时,可以设置为“10”;为3比特时,可以设置为“100”。
表1:
2比特重传指示域的比特状态 偏移值
00 无,即不重传
01 3
10 5
11 7
表2:
3比特重传指示域的比特状态 偏移值
000 无,即不重传
001 2
010 3
011 4
100 5
101 6
110 7
111 8
需要说明的是,上述表1和表2仅是举例说明,其他比特数,以及其他比特状态也同样可以应用于本实施例。
方式2:重传指示信息采用位图(bitmap)方式指示,类似上述方式1,网络设备确定要在时隙5、6、7、8中的第一PDCCH中设置假设第一PDCCH 中重传指示信息指示时隙4为第一时间单元;例如根据上下行配比,一个时间段定义为半个无线帧,即5个时隙,确定重传指示域为5比特,每比特分别对应一个时隙,则假设将PDCCH传输所在的半个无线帧之前的半个无线帧确定为bitmap对应的区域,则确定当前无线帧中的前半帧(即时隙0-5)为重传指示信息对应的时间段,即时隙5-8中传输的第一PDCCH中的5比特重传指示信息状态为“00001”,表示指示时隙4为第一时间单元,时隙4中被丢弃第一UCI(eMBB的HARQ-ACK)需要在时隙9中进行传输;又例如以一个无线帧为一个时间段,重传指示域为10比特,每比特分别对应一个时隙,则假设将PDCCH传输所在的无线帧确定为bitmap对应的区域,即时隙5-8中传输的PDCCH中的10比特重传指示域状态为“0000100000”,表示指示时隙4为第一时间单元,时隙4中被丢弃的第一UCI(eMBB的HARQ-ACK)需要在时隙9中进行传输;
方式二:网络设备可以仅在时隙8中的调度PDSCH传输的第一PDCCH中将重传指示信息设置为指示时隙4为第一时间单元的指示状态,则在上述过程中,只需要将时隙8中的第一PDCCH中的A比特(对应上述方式1)或B比特(对应上述方式2)设置为对应的内容,而其他时隙中的重传指示信息都设置为指示不重传即可,具体内容不再赘述。
进一步的,网络设备在时隙9中,在同一个PUCCH资源上,接收原本在时隙9中要传输的时隙5-8中的PDSCH对应的4比特HARQ-ACK(即第二UCI),以及被指示在时隙9中重传的原时隙4中的对应时隙0-3中的PDSCH的3比特HARQ-ACK(即第一UCI)。且可以根据约定方式认为第二UCI在前,第一UCI级联在第二UCI之后,则根据级联后的UCI总比特数,确定预先配置的PUCCH资源集合中的一个集合,其中,不同的资源集合对应不同的UCI比特数区间。之后根据最后一个第一PDCCH(即时隙8中的)中的PUCCH资源指示域确定这个集合中的一个PUCCH资源,在这个PUCCH资源上接收第一UCI和第二UCI,并从中按照级联顺序,分离出第一UCI和第二UCI。
该实施例中,终端的行为可以包括如下:
确定时隙4中因为其调度了一个承载URLLC的PUSCH导致了PUCCH 资源1上的第一UCI(eMBB HARQ-ACK)被丢弃,终端可以根据后续接收到的第一PDCCH中的重传指示信息的具体指示来确定在后续时隙中进行时隙4中的第一UCI的重传,具体可以包括如下方式:
方式一、假设对应在同一个时隙进行HARQ-ACK反馈的第一PDCCH中的重传指示域的指示值相同,该方式中可以包括以下两种方式:
方式1:重传指示信息指示偏移值,根据时隙5-8中的第一PDCCH中的K1指示域分别为4、3、2、1,都确定在时隙9中通过PUCCH进行HARQ-ACK传输,当假设重传指示域为2比特时,可以在时隙5-8中的第一PDCCH中获得重传指示域都为“10”,则确定以时隙9为第二时间单元,作为参考时,根据上述表1,确定偏移值为5个时隙,则确定时隙9-5=4为需要重传UCI的时隙,即第一时间单元。因此确定将时隙4中的被丢弃的第一UCI在时隙9中进行重传;当假设重传指示域为3比特时,可以在时隙5-8中的第一PDCCH中获得重传指示域都为“100”,则确定以时隙9为第二时间单元,作为参考时,根据上述表1,确定偏移值为5个时隙,则确定时隙9-5=4为需要重传UCI的时隙,即第一时间单元,因此确定将时隙4中的被丢弃的第一UCI在时隙9中进行重传;
方式2:重传指示域为bitmap指示方式,根据时隙5-8中的第一PDCCH中的K1指示域分别为4、3、2、1,都确定在时隙9中通过PUCCH进行HARQ-ACK传输;采用同网络设备侧方式一致时间段划分方式,例如根据上下行配比,一个时间段定义为半个无线帧,即5个时隙,确定重传指示域为5比特,每比特分别对应一个时隙,则假设将第一PDCCH传输所在的半个无线帧之前的半个无线帧确定为bitmap对应的区域,则确定当前无线帧中的前半帧(即时隙0-5)为重传指示域对应的时间段,则在时隙5-8中的第一PDCCH中获得的5比特重传指示域都为“00001”,表示指示时隙4为第一时间单元,时隙4中被丢弃的第一UCI需要在时隙9中进行传输;又例如以一个无线帧为一个时间段,重传指示域为10比特,每比特分别对应一个时隙,则假设将PDCCH传输所在的无线帧确定为bitmap对应的区域,即在时隙5-8中的PDCCH中获得的10比特重传指示域都为“0000100000”,表示指示时隙4为第一时间单元,时隙4中被丢弃的第一UCI需要在时隙9中进行传输。
方式二、假设对应在同一个时隙进行HARQ-ACK反馈的第一PDCCH中的重传指示信息的指示值不同,根据最后一个第一PDCCH中的重传指示信息确定是否重传,即后面的第一PDCCH的重传指示域可以更新前面的内容,则除了仅根据时隙8中的第一PDCCH中的重传指示域按照上述方式1或方式2来解析确定哪个时隙中的第一UCI在时隙9进行重传之外,其他的描述同上,不再赘述。
进一步的,终端在时隙9中,在同一个PUCCH资源上,发送原本在时隙9中要传输的时隙5-8中的PDSCH对应的4比特HARQ-ACK(即第二UCI),以及被指示在时隙9中重传的原时隙4中的对应时隙0-3中的PDSCH的3比特HARQ-ACK(即第一UCI),可以根据约定方式认为第二UCI在前,第一UCI级联在第二UCI之后,则根据级联后的UCI总比特数,确定预先配置的PUCCH资源集合中的一个集合,并根据最后一个第一PDCCH(即时隙8中的第一PDCCU)中的PUCCH资源指示域确定这个集合中的一个PUCCH资源,在这个PUCCH资源上发送级联后的第一UCI和第二UCI。
实施例2:
该实施例与实施例1的主要区别在于,实施例2采用半静态码本,而实施例2采用动态码本。进一步的,该实施例中,在实施例1描述的时隙4和时隙9中分别根据动态码本的确定方式,根据K1值定位在时隙4中进行HARQ-ACK反馈的PDSCH所对应的PDCCH中的总计下行分配索引(T-DAI,Total-Downlink Assignment Index)确定时隙4中包含X1比特HARQ-ACK,确定时隙9中包含X2比特HARQ-ACK,X1是根据时隙0-4中实际调度了多少个PDSCH传输决定的,X2是根据时隙5-8中实际调度了多少个PDSCH传输决定的,其他方式可以同实施例1,不再赘述。
实施例3:
该实施例在实施例1和2的基础上,对于上述方式一,在时隙5-8中的如果仅发送了一个包含了上述重传指示信息的第一PDCCH,且这个第一PDCCH没有调度PDSCH传输,或者这个第一PDCCH调度的PDSCH传输并不在时隙9中传输,比如包含重传指示信息的第一PDCCH所使用的DCI中包含两个K1指示域,一个用于指示重传传输所在的时隙,一个用于指示第 一PDCCH所调度的PDSCH的HARQ-ACK传输所在的时隙,则假设重传所在的时隙还是时隙9,按照上述重传指示信息的定义,可以确定时隙4中被丢弃的第一UCI要在时隙9中进行重传,而时隙9中仅存在这个重传,没有其他UCI传输,则可以按照约定方式,假设时隙4中原本传输第一UCI的PUCCH资源为PUCCH资源1,则在时隙9中,使用PUCCH资源1传输3比特原时隙4中的第一UCI;或者,根据包含重传指示信息的第一PDCCH中的PUCCH资源指示域,按照协议约定确定一个PUCCH资源,即根据3比特第一UCI的比特数确定一个PUCCH资源集合,在这个集合中,根据PUCCH资源指示域的指示域确定一个PUCCH资源,在这个PUCCH资源上重新传输3比特第一UCI;如果第一PDCCH调度了PDSCH在其他时隙进行HARQ-ACK反馈,第一PDCCH中的资源指示信息也可以用于被调度的PDSCH在其他反馈时隙中确定PUCCH资源,虽然根据同一个指示域确定资源,但因为PUCCH在不同时隙传输,不存在冲突。
实施例4:基于上述实施例1-3,如果上述方式1中重传指示信息的指示状态可以指示多个偏移值,或者,如果上述方式2中的bitmap中包含超过1个“1”状态,则可以确定多个第一时间单元是需要进行第一UCI重传的,例如确定时隙2和是4都为第一时间单元,都需要在时隙9中进行第一UCI重传,假设时隙2中原本的第一UCI为2比特,使用PUCCH资源1传输,时隙4中原本的第一UCI为3比特,使用PUCCH资源2传输,则如果在时隙9中不存在其他UCI传输的情况下,可以存在如下任一方式:
一种方式:时隙2中的2比特第一UCI和时隙3中的3比特第一UCI级联在一起,得到5比特UCI,在时隙9中使用PUCCH资源2传输,或者根据级联的比特数以及PDCCH中的PUCCH资源指示域确定的PUCCH资源传输(具体确定过程同上,不赘述);
另一种方式:时隙2中的2比特第一UCI在时隙9中使用PUCCH资源1传输,时隙4中的3比特第一UCI在时隙9中使用PUCCH资源2传输,其中PUCCH资源1和PUCCH资源2在时隙9中不重叠。
如果在时隙9中存在第二UCI传输的情况下,可以存在如下任一方式:
一种方式:时隙2中的2比特第一UCI和时隙3中的3比特第一UCI与 第二UCI级联在一起,例如时隙2中的2比特第一UCI和时隙3中的3比特第一UCI按照时间顺序级联,然后进一步级联在时隙9的第二UCI之后;在时隙9中,在根据级联的比特数以及PDCCH中的PUCCH资源指示域确定的PUCCH资源传输(具体确定过程同上,不赘述);
另一种方式:时隙2中的2比特第一UCI在时隙9中使用PUCCH资源1传输,时隙4中的3比特第一UCI在时隙9中使用PUCCH资源2传输,时隙9中的第二UCI,在根据其比特数以及PDCCH中的PUCCH资源指示域确定的PUCCH资源传输(具体确定过程同上,不赘述);其中,PUCCH资源1和PUCCH资源2以及第二UCI的PUCCH资源在时隙9中都不重叠,或者,如果PUCCH资源1和PUCCH资源2中存在与第二UCI的PUCCH资源重叠的PUCCH资源,则对于重叠的PUCCH资源,将其对应的UCI级联在一起,在根级联后的比特数以及PDCCH中的PUCCH资源指示域确定的PUCCH资源传输(具体确定过程同上,不赘述);
需要说明的是,上述实施例1至实施例4仅是以第一PDCCH为调度PDSCH传输的PDCCH进行举例说明,本公开实施例中,也可以将调度PDSCH传输的PDCCH替换为指示SPS资源释放的PDCCH,且执行过程实施例1至实施例4的过程相同。
上述上述实施例1至实施例4仅是以不同优先级之间存在冲突导致的UCI丢弃,其他原因的UCI丢弃同样适用。
上述上述实施例1至实施例4主要是以HARQ-ACK作为丢弃第一UCI为例,其他UCI如CSI、SR或者各种UCI组合的丢弃,如果支持进行重复传输,则同理。
在上述实施例1至实施例4中将时隙替换为子时隙的实现过程同理。
另外,上述实施例1至实施例4仅是以一个载波为例,如果是载波聚合,根据协议中定义的码本产生方式,仅影响产生的码本大小和内容,不影响重传的指示和具体重传过程。
上述在被丢弃的第一UCI进行重新传输的时隙中,如果还存在其他与被丢弃的UCI类型不同的UCI,例如上述被丢弃的是HARQ-ACK,而时隙9中存在CSI和/或SR传输时,如果CSI和/或SR的PUCCH资源与HARQ-ACK 在时隙9中进行重传的PUCCH资源不重叠,则可以独立传输,如果重叠,则按照协议中定义中的UCI复用传输方式进行复用传输,比如先按照优先级进行取舍,丢弃低优先级,传输高优先级,而如果优先级相同,则按照复用规则进行复用传输,比如SR和HARQ-ACK,是根据各自使用的PUCCH资源格式的不同选择不同的方案,比如都使用PUCCH格式1,则当SR为positive(正时),在SR的PUCCH资源上传输HARQ-ACK,隐式表达同时存在positive SR,比如HARQ-ACK使用PUCCH格式0时,在HARQ-ACK的PUCCH资源上选择与SR状态相对应的循环移位进行传输,隐式通过选择的循环移位不同表达是否同时存在positive SR,比如HARQ-ACK使用PUCCH格式2、3、4中的一种时,SR比特与HARQ-ACK级联在一起进行联合编码传输。
进一步的,对于HARQ-ACK和CSI,如果HARQ-ACK使用PUCCH格式2、3、4中的一种,根据CSI和HARQ-ACK的总比特数确定PUCCH资源,资源不足时,则可以丢弃部分CSI,如果HARQ-ACK为SPS PDSCH的HARQ-ACK,则CSI和HARQ-ACK级联在一起进行联合编码,在CSI对应的PUCCH资源上传输。
本公开实施例中,通过UCI重传,可以避免因为各种冲突导致的UCI丢弃带来的系统传输性能的下降,提高系统整体传输性能。
