在进行本公开实施例的说明时,首先对下面描述中所用到的一些概念进行解释说明。
上行控制信息(Uplink Control Information,UCI)包含:混合自动重传请求确认(Hybrid Automatic Repeat request-ACKnowledgment,HARQ-ACK)、信道状态信息(Channel State Information,CSI)、调度请求(Scheduling Request,SR)等信息。其中,HARQ-ACK是肯定确认(ACKnowledgment,ACK)和否定确认(Non-ACKnowledgment,NACK)的统称,用于针对物理下行共享信道(Physical Downlink Shared Channel,PDSCH)或指示半持续调度(Semi-Persistent Scheduling,SPS)资源释放(release)的物理下行控制信道(Physical Downlink Control Channel,PDCCH)(又称SPS PDSCH release)进行反馈,告知基站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,从而帮助基站更好的进行下行调度,例如根据CSI进行调制编码等级(Modulation and Coding Scheme,MCS)选择、配置适当的资源块(Resource Block,RB)资源等;SR用于当终端有上行业务需要传输时,向基站请求携带上行业务的物理上行共享信道(Physical Uplink Shared Channel,PUSCH)的传输资源。UCI在PUCCH上传输。PUCCH总是在固定的载波上传输。
对于载波聚合(Carrier aggregation,CA)场景:
PUCCH在主载波(Primary Component Carrier,PCC)或主小区(Primary Cell,PCell)上传输,当CA场景中配置了PUCCH在辅载波(Secondary Component Carrier,SCC)或辅小区(Secondary Cell,SCell)上传输时,聚合的载波可以分为两个PUCCH载波组,每个PUCCH载波组中存在一个指定的载波传输PUCCH,包含PCC(或PCell)的载波组为主PUCCH载波组,PUCCH在PCC(或PCell)上传输,辅PUCCH载波组中都是SCC(或SCell),高层信令配置其中一个SCC(或SCell)上可以传输PUCCH,称之为PUCCH SCell。每个载波组中的所有载波上的下行传输(包括PDSCH,以及需要进行 HARQ-ACK反馈的PDCCH)的HARQ-ACK都在一个指定的载波上的PUCCH中传输。
对于双连接(Dual-connective,DC)场景:
存在主载波组(Master Carrier Group,MCG)和辅载波组(Secondary Carrier Group,SCG)两个载波组,在每个载波组中一个指定的载波上传输PUCCH,其中MCG包含PCC,PUCCH在PCC上传输,SCG中都是SCC,PUCCH在其中一个预先配置的SCC(或称为PSCell)上传输。
5G NR中支持灵活的定时关系。对于具有动态调度(即PDCCH或DCI调度的传输)的下行传输,包括PDCCH调度的PDSCH、DCI触发的type3HARQ-ACK码本传输、需要进行HARQ-ACK的PDCCH本身等,例如:指示下行SPS资源释放的PDCCH、指示SCell dormancy(休眠)的PDCCH等。HARQ-ACK传输所在的时隙或子时隙是可以基于对应的PDCCH或DCI(PDCCH和DCI可以认为等价,DCI是PDCCH的具体传输格式,PDCCH是DCI的传输信道)中的反馈定时指示域来确定。
以PDSCH为例,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,即假设上行和下行SCS相同时,时隙n中传输的PDSCH在时隙n+K1中进行HARQ-ACK传输,如图1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。协议中规定,K1的值是以时隙(slot)为单位的,即K1=1表示间隔1个时隙;或者,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。DCI中是否存在反馈定时指示域可以根据高层信令配置的指示比特数是否大于0得到,也可以根据高层信令配置的反馈定时的后选值K1 集合中的元素个数来确定,当元素个数大于1个时,按照元素个数确定指示的比特数(例如ceil(log2N),N为元素个数,ceil为向上取整),当元素个数仅有一个时,DCI中不存在指示域,直接使用这一个值确定反馈定时。
对于半静态的UCI,例如CSI、SR以及对应SPS PDSCH的HARQ-ACK(简称SPS HARQ-ACK),承载半静态UCI的PUCCH传输所在的时隙或者子时隙是半静态确定的,称之为半静态的反馈时序。例如CSI和SR是根据高层信令配置的周期和偏移值,确定每个传输机会所在的时隙以及时隙中的符号位置,从而周期性的在对应的时隙以及相应的符号位置中使用高层信令配置的PUCCH资源进行传输。SPS HARQ-ACK可以根据指示SPS PDSCH激活的PDCCH中的反馈定时指示域所指示的K1值确定HARQ-ACK反馈位置(即所在时隙或子时隙)。如果指示SPS PDSCH激活的PDCCH中如果不存在反馈定时指示域,则可以按照高层信令配置的一个K1值确定HARQ-ACK反馈位置。
承载CSI或SR的PUCCH资源是高层信令对每个CSI报告(report)或SR配置分别配置的一个PUCCH资源。系统中可以为承载具有动态调度的下行传输的HARQ-ACK配置一个或多个PUCCH资源集合,如果仅配置一个PUCCH资源集合,则承载具有动态调度的下行传输的HARQ-ACK的PUCCH资源可以是根据调度PDCCH中的PUCCH资源指示域从这个资源集合中的多个资源中选择的一个资源,如果一个资源集合中包含超过8个资源,可以结合PDCCH的控制信道单元(Control Channel Element,CCE)信息以及其中的PUCCH资源指示域共同在多个资源中选择的一个资源;如果配置了多个PUCCH资源集合,每个PUCCH资源集合对应不同的UCI传输比特数,先根据PUCCH承载的UCI比特数选择其中一个PUCCH资源集合,在选择的PUCCH资源集合中,根据调度PDCCH中的PUCCH资源指示域从这个资源集合中的多个资源中选择的一个资源。如果一个资源集合中仅存在一个PUCCH资源,PDCCH中可以不存在PUCCH资源指示域,直接使用这个资源进行传输。
NR中还支持灵活的上下行时隙配比,一方面可以通过高层信令半静态的配置一段时间中所包含的多个时隙中哪些是下行时隙,哪些是上行时隙以及 哪些是同时包含上行和下行的混合时隙,例如高层信令可以配置全下行时隙的起点、连续的全下行时隙个数、全下行时隙之后的一个时隙中的下行符号的个数、第一个全上行时隙之前的时隙中的上行符号个数、连续的全上行的时隙个数或结束位置等。其中,没有指示上行或下行符号的符号位置都认为是灵活符号,灵活符号是可以动态的使用做下行传输或上行传输的。此外,还可以通过动态指示改变上下行配比,例如通过周期性的发送指示时隙格式(Slot Format Indication,SFI)的DCI来通知一个或多个连续的时隙中,每个时隙中的上下行符号的划分,从而做到对每个时隙内部的上下行符号个数的调整。
URLLC的两个指标包括:高可靠传输,例如达到10-5甚至更低的BLER(Block Error Rate,误块率)性能;低时延,例如空口单向传输时间不超过0.5ms或1ms等。URLLC的UCI传输时延会影响URLLC业务的传输时延,比如HARQ-ACK反馈的时延会影响PDSCH的重传,CSI反馈的时延会影响PDSCH的调度,从而影响下行业务的时延;SR的时延会影响PUSCH的时延,从而影响上行业务的时延。为了降低PUCCH传输时延,提出了PUCCH切换载波传输的方式。
具体地,本公开的实施例提供了一种PUCCH传输方法,能够实现使用PUCCH载波切换的方法进行PUCCH传输。
如图2所示,本公开的实施例提供了一种PUCCH传输方法,应用于终端,具体包括以下步骤:
步骤21:终端确定在第一载波上进行物理上行控制信道PUCCH传输的第一时间单元。
其中,所述第一载波为所述终端进行PUCCH载波切换前传输PUCCH的载波,所述终端确定在第一载波的第一时间单元中进行PUCCH载波切换。所述第一载波为原本配置传输PUCCH的载波,例如:PCell或PUCCH Scell或PScell等,终端可以确定在第一载波上传输PUCCH的时间单元位置,即确定所述第一时间单元,例如对于HARQ-ACK,可以根据动态或半静态的反馈定时关系来确定承载HARQ-ACK的PUCCH传输所在的时间单元(例如时隙或子时隙),对于CSI或SR,可以根据在原本传输PUCCH的载波上配置 的传输周期和偏移确定周期性的传输机会,例如对于CSI,配置的周期为2个时隙,偏移为0(即相对于一个无线帧中的第一个时隙的偏移值),则确定每个无线帧中的时隙#0、2、4、6、8等是CSI传输所在的时隙。
步骤22:所述终端根据所述第一时间单元,确定在第二载波上进行PUCCH传输的第二时间单元。
所述第二载波为所述终端进行PUCCH载波切换后传输PUCCH的载波。即所述第二载波为可以通过PUCCH载波切换进行PUCCH传输的载波。具体地,所述终端被配置或允许在所述第一载波和所述第二载波之间进行PUCCH切换。在一种实施例中,是从第一载波切换到第二载波,也就是通常情况下PUCCH是在第一载波传输,当满足切换条件需要进行载波切换时,从第一载波切换到第二载波上传输PUCCH。
该实施例中,在需要进行PUCCH载波切换时,终端基于PUCCH载波切换前的第一载波上确定的进行PUCCH传输的第一时间单元,确定PUCCH载波切换后的第二载波上进行PUCCH传输的第二时间单元。
步骤23:所述终端在所述第二载波的第二时间单元中发送PUCCH;
终端基于第一载波上确定的进行PUCCH传输的第一时间单元,确定出第二载波上进行PUCCH传输的第二时间单元后,利用所述第二载波的第二时间单元发送PUCCH,完成PUCCH载波切换后的PUCCH传输。在该情况下,终端在所述第一载波的第一时间单元不再发送PUCCH,PUCCH的发送行为切换到第二载波的第二时间单元上进行。
该实施例中,在第一载波上需要传输PUCCH的第一时间单元中,如果确定需要进行PUCCH载波切换,则可以根据预定规则确定PUCCH载波切换之后的目标载波为第二载波,根据所述第一载波上的第一时间单元,确定第二载波上的第二时间单元,并在第二载波的第二时间单元中进行PUCCH传输。其中,所述第二载波的第二时间单元中传输的PUCCH承载的信息为进行PUCCH载波切换之前需要在第一载波的第一时间单元中传输的PUCCH上的UCI(也可以仅是其中的部分信息),则在PUCCH载波切换后,无需在第一载波的第一时间单元中进行PUCCH传输,进而实现PUCCH从一个载波切换到另一个载波上传输。
需要说明的是,切换到第二载波的第二时间单元进行传输的PUCCH,在第二载波的第二时间单元中的具体传输PUCCH的时域资源(例如在第二时间单元中占用的具体符号位置和数量)和频域资源(例如RB个数和位置等,还可以包含码域资源,例如正交序列,循环移位等参数)可以按照其他的规则确定,在此不做限定。
本公开的实施例,在需要进行PUCCH载波切换时,基于PUCCH载波切换前的第一载波上确定的进行PUCCH传输的第一时间单元,确定切换后的第二载波上进行PUCCH传输的第二时间单元,从而在不需要额外信令通知或指示的基础上,确定出PUCCH载波切换后的载波上传输PUCCH的时间单元,能够保证PUCCH载波切换传输的正常实现,同时不增加额外信令开销。

方式(2):确定所述第二载波上与所述第一时间单元重叠的时间单元中的目标时间单元,为所述第二时间单元。
所述第二时间单元可以为与所述第一载波上的第一时间单元重叠的时间单元中的特定的一个时间单元,例如:在第一载波的SCS更小或第一载波上的PUCCH传输时间单元更大的情况,可能存在一个第一时间单元与多个第二时间单元重叠,此时可以将多个所述第二时间单元中的一个特定的时间单元(即所述目标时间单元)作为PUCCH载波切换后的第二载波上进行PUCCH传输的时间单元。

c3:与所述第二载波上的高层信令配置的上行传输在时域上不重叠;即不与第二载波上的高层信令配置的上行传输在时域上重叠的PUCCH资源为所述可用PUCCH资源。其中,所述高层信令配置的上行传输即没有PDCCH调度触发的上行传输,例如:探测参考信号(Sounding Reference Signal,SRS)、半持续信道状态信息(Semi-Persistent CSI,SP-CSI)、配置授权(Configured Grant PUSCH,CG PUSCH)等半静态的上行传输。
c4:与所述第二载波上的高层信令配置的上行传输在频域上不重叠;即不与第二载波上的高层信令配置的上行传输在频域上重叠的PUCCH资源为所述可用PUCCH资源。

例如定义为:T proc,1=((N 1+d 1,1+d 1,2)(2048+144)·κ2 )·T c,其中N 1是与需要进行HARQ-ACK反馈的PDSCH的处理能力相关的处理时间,根据参考μ在处理能力列表中选择一个数值,κ为长期演进技术(Long Term Evolution,LTE)采用间隔与NR采样间隔之间的比值,μ为SCS的索引,参考μ是调度PDSCH的PDCCH、PDSCH本身、PUCCH本身等对应的μ的最小值,T C为NR采用间隔,d 1,1为不同上行信道上传输HARQ-ACK的处理时间偏移值,如果在PUCCH上传输d 1,1=0,如果在PUSCH上传输d 1,1=1,d 1,2为 与PDSCH所占用的符号数有关的处理时间偏移。
需要说明的是,所述可用PUCCH资源需要满足的第一条件的具体内容根据需求设置,即所述第一条件可以包括c1~c5中的一项或者多项。例如:与所述第二载波上的下行符号不重叠,且与所述第二载波上的同步信号块SSB所占用的符号不重叠的PUCCH资源为所述可用PUCCH资源;与所述第二载波上的高层信令配置的上行传输在时域和频域上不重叠,且满足PUCCH承载的信息的准备时间需求的PUCCH资源为所述可用PUCCH资源。所述可用PUCCH资源需要满足的第一条件的具体内容根据需求设置。其余多种组合情况不做赘述。

对于(i)和(j),所述第一载波上的PUCCH所占用的符号可能为时域上的多个符号,不同的符号可能与不同的时间单元重叠,则存在多个时间单元与PUCCH所占用的符号重叠的情况,此时可以选择其中的一个时间单元作为所述目标时间单元,例如,选择与所述第一载波上的PUCCH所占用的符号集合中的符号存在重叠的第一个时间单元或者最后一个时间单元。
方式(3):根据需要进行载波切换的PUCCH对应的下行控制信息DCI 的第一指示域的指示信息,确定所述第二时间单元;
具体地,所述第一指示域的指示信息,可以包括以下其中一项:
所述第二时间单元的信息;
相对于所述第一载波上的PUCCH的时域位置的时域偏移;
相对于所述第一载波上的所述第一时间单元的时域偏移。
该实施例中,对于具有对应的DCI的PUCCH,在进行PUCCH载波切换时,可以基于DCI中的一个第一指示域来确定在第二载波上传输PUCCH的第二时间单元,所述第一指示域可以是所述DCI中所包含的现有指示域的重用或者是新增的指示域。所述第一指示域用来指示一个第二载波上的第二时间单元(即所述第一指示域的指示信息直接指示所述第二时间单元的信息),或者指示相对于所述第一载波上的PUCCH的时域位置的时域偏移,或者指示相对于所述第一载波上的第一时间单元的时域偏移。所述时域偏移的单位可以是符号或者PUCCH传输时间单元,符号或PUCCH传输时间单元的单位为第二载波对应的单位。
方式(4):根据所述第一时间单元的预配置信息,确定所述第二时间单元。
具体地,所述第一时间单元的预配置信息,包括以下其中一项:
所述第二时间单元的信息;
相对于所述第一载波上的PUCCH的时域位置的时域偏移;
相对于所述第一载波上的所述第一时间单元的时域偏移。
该实施例中,可以对第一载波上的每个可以进行PUCCH切换的第一时间单元预先定义或预先配置一个第二载波上对应的第二时间单元(即预先定义或者预先配置所述第二时间单元的信息),或者预先定义或预先配置一个时域偏移值,该时域偏移值用来指示第二载波上的PUCCH相对于第一载波上的PUCCH的时域位置的时域偏移,或者指示相对于所述第一时间单元的时域偏移。所述时域偏移的单位可以是符号或者PUCCH传输时间单元,符号或PUCCH传输时间单元的单位为第二载波对应的单位。
作为一个可选实施例,所述第二载波的子载波间隔SCS大于或者等于所述第一载波的SCS。
该实施例中,所述第一载波和所述第二载波的SCS相同;或者所述第一载波的SCS不大于所述第二载波的SCS。例如:所述第二载波的SCS为15kHz,则所述第一载波的SCS也为15kHz;又例如:所述第二载波的SCS为30kHz,所述第一载波的SCS可以为15kHz或30kHz等。
作为一个可选实施例,所述第一时间单元的单位与所述第二时间单元的单位相同;例如所述第一时间单元和所述第二时间单元的单位都是时隙,或者都是相同长度的子时隙。
或者,所述第一时间单元的单位与所述第二时间单元的单位不同,例如所述第一时间单元包含的符号数,小于或者等于所述第二时间单元包含的符号数。即所述第一载波上的PUCCH传输时间单元不大于所述第二载波上的PUCCH传输时间单元。例如:所述第一载波上的PUCCH传输时间单元为时隙,则第二载波上的PUCCH传输时间单元也为时隙;第一载波上的PUCCH传输时间单元为长度是7符号的子时隙,则第二载波上的PUCCH传输时间单元可以为时隙或长度是7符号的子时隙,但不能是长度是2符号的子时隙。
其中,传输时间单元的单位可以是时隙、子时隙中的一种,子时隙可以有不同的长度,如2符号子时隙或者7符号子时隙。如果第二载波上没有配置PUCCH传输时间单元的单位,则确定按照与第一载波上相同的PUCCH传输时间单元或者预先约定的PUCCH传输时间单元进行传输。
下面通过具体实施例说明本公开实施例的所述PUCCH传输方法的实现过程。
示例一:
如图3所示,第一载波为进行PUCCH载波切换前配置的传输PUCCH的载波(例如PCell、PUCCH Scell或PScell等),第二载波为PUCCH可以通过载波切换进行PUCCH传输的载波,第一载波和第二载波的SCS相同。在第一载波和第二载波上,PUCCH均按照时隙为传输时间单元进行传输,即每个PUCCH的时域资源均不会超过一个时隙,即第一载波上的反馈定时的单位为时隙(即时隙为PUCCH传输时间单元的单位)。
该示例一中,可以根据PDCCH中的反馈定时指示域所指示的k1,以及PDCCH所调度的PDSCH传输所在的时隙m,确定PDSCH的HARQ-ACK 反馈在时隙(m+k1)即时隙n中传输(具体在时隙n中的传输资源,例如符号位置、RB资源等可以根据PDCCH中的PUCCH资源指示域获得,在此不做限定);则当确定第一载波上需要在时隙n中进行PUCCH传输,且根据PUCCH载波切换的规则(具体如何确定的规则不做限定),确定第一载波的时隙n中需要进行PUCCH载波切换,则按照本公开实施例的方式(1),可以确定时隙n为第一载波上的第一时间单元,确定与其重叠的第二载波上的时隙n为第二时间单元,则可以确定进行PUCCH载波切换后,在第二载波上的时隙n中传输PUCCH,从而不需要任何的额外信令指示,就可以确定PUCCH载波切换之后,目标载波上传输PUCCH的时间单元位置。
示例二:
如图4所示,第一载波为进行PUCCH载波切换前配置的传输PUCCH的载波,第二载波为PUCCH可以通过载波切换进行PUCCH传输的载波,第一载波和第二载波的SCS相同。假设在第一载波上PUCCH按照长度为7个符号的子时隙为传输时间单元进行传输,即在第一载波上的反馈定时k1的单位也是子时隙;在第二载波上PUCCH按照时隙为传输时间单元进行传输。
在该示例二中,按照反馈定时确定在第一载波的子时隙(m+k1)即子时隙2n中进行PUCCH传输,且根据PUCCH载波切换的规则,确定第一载波的子时隙2n中需要进行PUCCH载波切换,则按照本公开实施例的方式(1),可以确定子时隙2n为第一载波上的第一时间单元,确定与之重叠的第二载波上的第二时间单元为时隙n,则确定经过PUCCH载波切换后,在第二载波上的时隙n中传输PUCCH,从而不需要任何的额外信令指示,就可以确定PUCCH载波切换之后,目标载波上传输PUCCH的时间单元位置。
示例三:
第一载波为进行PUCCH载波切换前配置的传输PUCCH的载波,第二载波为PUCCH可以通过载波切换进行PUCCH传输的载波,第一载波的SCS为15kHz,第二载波的SCS为30kHz。PUCCH在第一载波和第二载波上均按照时隙为传输时间单元进行传输,则当确定第一载波上需要在时隙n中进行PUCCH传输,且根据PUCCH载波切换的规则,确定第一载波的时隙n中需要进行PUCCH载波切换,则按照本公开实施例的方式(2),可以确定时隙n 为第一载波上的第一时间单元,确定与之重叠的第二载波上的第二时间单元存在多个,分别为时隙2n和2n+1,则确定多个与第一时间单元重叠的时间单元中的目标时间单元为所述第二时间单元,所述目标时间单元可以通过以下多种方式确定:
方式一,将第二载波上的多个时间单元中的第一个时间单元作为PUCCH传输的第二时间单元,即确定在第二载波上的时隙2n中传输PUCCH,如图5所示;
方式二,将第二载波上的多个时间单元中的最后一个时间单元作为PUCCH传输的第二时间单元,即确定在第二载波上的时隙2n+1中传输PUCCH,如图6所示;
方式三,将第二载波上的多个时间单元中存在可用PUCCH资源的第一个时间单元作为PUCCH传输的第二时间单元。例如:假设PUCCH资源不与高层信令配置的下行符号或SSB符号重叠,即时隙2n中存在可用PUCCH资源,则确定在第二载波上的时隙2n中传输PUCCH,如图5所示;假设时隙2n中不存在可用PUCCH资源,而2n+1中存在可用PUCCH资源(例如PUCCH资源不与高层信令配置的下行符号或SSB符号重叠),则确定在第二载波上的时隙2n+1中传输PUCCH,如图6所示;
方式四,将第二载波上的多个时间单元中存在可用PUCCH资源的最后一个时间单元作为PUCCH传输的第二时间单元。例如:假设时隙2n和时隙2n+1中均存在可用PUCCH资源,则确定在第二载波上的时隙2n+1中传输PUCCH。
方式五,根据第一载波上的第一时间单元中的PUCCH的起始符号(或者起始时刻)确定与该起始符号重叠的第二载波上的时间单元为第二时间单元,即确定在第二载波上的时隙2n中传输PUCCH,如图5所示。
方式六,根据第一载波上的第一时间单元中的PUCCH的结束符号(或者结束时刻)确定与结束时刻重叠的第二载波上的时间单元为第二时间单元,即确定在第二载波上的时隙2n+1中传输PUCCH,如图6所示。
方式七,将与所述第一时间单元重叠的时间单元中,与所述第一载波上的PUCCH所占用的符号集合中的符号存在重叠的第一个时间单元,确定为 第二时间单元。
方式八,将与所述第一时间单元重叠的时间单元中,与所述第一载波上的PUCCH所占用的符号集合中的符号存在重叠的最后一个时间单元,确定为第二时间单元。
示例四:
第一载波为进行PUCCH载波切换前配置的传输PUCCH的载波,第二载波为PUCCH可以通过载波切换进行PUCCH传输的载波,第一载波的SCS和第二载波的SCS相同,例如均为15kHz或者均为30kHz。PUCCH在第一载波上按照时隙为传输时间单元进行传输,PUCCH在第二载波上按照长度为7个符号的子时隙为传输时间单元进行传输,确定第一载波的时隙n中需要进行PUCCH载波切换,则按照本公开实施例的方式(2),可以确定时隙n为第一载波上的第一时间单元,确定与之重叠的第二载波上的第二时间单元存在多个,分别为子时隙2n和子时隙2n+1,则确定多个与第一时间单元重叠的时间单元中的目标时间单元为所述第二时间单元,所述目标时间单元可以通过以下多种方式确定:
方式一,将第二载波上的多个时间单元中的第一个时间单元作为PUCCH传输的第二时间单元,即确定在第二载波上的子时隙2n中传输PUCCH,如图7所示;
方式二,将第二载波上的多个时间单元中的最后一个时间单元作为PUCCH传输的第二时间单元,即确定在第二载波上的子时隙2n+1中传输PUCCH,如图8所示;
方式三,将第二载波上的多个时间单元中存在可用PUCCH资源的第一个时间单元作为PUCCH传输的第二时间单元。例如:假设PUCCH资源不与高层信令配置的下行符号或SSB符号重叠,即子时隙2n中存在可用PUCCH资源,则确定在第二载波上的子时隙2n中传输PUCCH,如图7所示;假设子时隙2n中不存在可用PUCCH资源,而子时隙2n+1中存在可用PUCCH资源,则确定在第二载波上的子时隙2n+1中传输PUCCH,如图8所示;
方式四,将第二载波上的多个时间单元中存在可用PUCCH资源的最后一个时间单元作为PUCCH传输的第二时间单元。例如:假设子时隙2n和子 时隙2n+1中均存在可用PUCCH资源,则确定在第二载波上的子时隙2n+1中传输PUCCH。
方式五,根据第一载波上的第一时间单元中的PUCCH的起始符号(或者起始时刻)确定与该起始符号重叠的第二载波上的时间单元为第二时间单元,即确定在第二载波上的子时隙2n中传输PUCCH,如图7所示。
方式六,根据第一载波上的第一时间单元中的PUCCH的结束符号(或者结束时刻)确定与结束时刻重叠的第二载波上的时间单元为第二时间单元,即确定在第二载波上的子时隙2n+1中传输PUCCH,如图8所示。
方式七,将与所述第一时间单元重叠的时间单元中,与所述第一载波上的PUCCH所占用的符号集合中的符号存在重叠的第一个时间单元,确定为第二时间单元。
方式八,将与所述第一时间单元重叠的时间单元中,与所述第一载波上的PUCCH所占用的符号集合中的符号存在重叠的最后一个时间单元,确定为第二时间单元。
本公开的上述实施例中,仅以部分SCS作为举例,替换为其他SCS的情况类似,在此不做赘述;上述仅以时隙作为PUCCH传输时间单元作为举例,任何一个载波上改变PUCCH传输时间单元为子时隙,或两个载波上分别是不同符号个数的子时隙,比如一个载波的传输时间单元是2个符号的子时隙,另一个载波的传输时间单元是7个符号的子时隙,具体执行方式类似,在此不做赘述;上述仅以PUCCH承载具有PDCCH调度的PDSCH的HARQ-ACK为例,将调度PDCCH的PDSCH替换为需要进行HARQ-ACK的PDCCH的情况类似,所不同的是此时HARQ-ACK可以是PDCCH本身的HARQ-ACK,当PUCCH承载其他UCI时的情况类似,所不同的可能是对于CSI和/或SR,在第一载波上的PUCCH传输所在的第一时间单元以及其中的具体资源是根据高层信令配置确定的,并不是基于PDCCH通知的。
上述示例一至示例四仅以确定第二时间单元的方式(1)和方式(2)为例进行说明,需要说明的是,还可以根据方式(3)和方式(4)确定在第二载波上进行PUCCH传输的第二时间单元,例如:根据需要进行载波切换的PUCCH对应的DCI中的第一指示域的指示,确定所述第二时间单元,或者 根据预定义或者预配置的信息确定所述第二时间单元。具体地,可以通过方式(3)或方式(4)直接确定在第二载波上传输PUCCH的第二时间单元,或者根据方式(3)或方式(4)中的方式确定一个偏移值,基于该偏移值以及第一时间单元确定第二载波上的第二时间单元,例如偏移值为相对于第一时间单元的起始位置开始的符号偏移,或者偏移值为相对于在第二载波上与第一时间单元重叠的第一个时间单元开始的偏移值,则比如第二载波上存在多个时间单元与第一时间单元重叠时,例如图5-8中所示的情况,可以根据偏移值是0还是1,来确定第二载波上的第二时间单元为与第一时间单元重叠的两个时间单元中的第一个时间单元还是第二个时间单元。
本公开的实施例以不同载波之间为同步CA的情况为例进行说明,即不同载波上的无线帧的边界为对齐的,则不同载波在相同的SCS情况下的时隙边界也是对齐的;需要说明的是,还也可以应用于非同步CA的情况,即不同载波之间的时隙编号相差一个固定的偏移值(offset),此时差别在于在相同的SCS的情况下,与第一载波上的时隙n对齐的第二载波上的并不一定是时隙n,可能是时隙m,m=n+offset,offset的单位是时隙,如果子载波间隔不同,offset会以一个参考SCS对应的时隙个数来体现。在这种情况下,使用本公开实施例的方式,依然可以确定出第二载波上对应的第二时间单元。
本公开的实施例,在需要进行PUCCH载波切换时,基于PUCCH载波切换前的第一载波上确定的进行PUCCH传输的第一时间单元,确定切换后的第二载波上进行PUCCH传输的第二时间单元,从而在不需要额外信令通知或指示的基础上,确定出PUCCH载波切换后的载波上传输PUCCH的时间单元,能够保证PUCCH载波切换传输的正常实现,同时不增加额外信令开销。
如图9所示,本公开的实施例提供了一种PUCCH传输方法,应用于网络侧设备,具体包括以下步骤:
步骤91、网络侧设备确定在第一载波上进行物理上行控制信道PUCCH传输的第一时间单元。
其中,所述第一载波为所述终端进行PUCCH载波切换前传输PUCCH的载波,所述终端确定在第一载波的第一时间单元中进行PUCCH载波切换。所述第一载波为原本配置传输PUCCH的载波,例如:PCell或PUCCH Scell 或PScell等。网络侧设备可以确定在第一载波上传输PUCCH的时间单元位置,即确定所述第一时间单元,所述第一时间单元即为进行PUCCH载波切换前所述网络侧设备接收PUCCH的时间单元位置。
例如对于HARQ-ACK,可以根据动态或半静态的反馈定时关系来确定承载HARQ-ACK的PUCCH传输所在的时间单元(例如时隙或子时隙),对于CSI或SR,可以根据在原本传输PUCCH的载波上配置的传输周期和偏移确定周期性的传输机会,例如对于CSI,配置的周期为2个时隙,偏移为0(即相对于一个无线帧中的第一个时隙的偏移值),则确定每个无线帧中的时隙#0、2、4、6、8等是CSI传输所在的时隙。
步骤92、所述网络侧设备根据所述第一时间单元,确定在第二载波上进行PUCCH传输的第二时间单元。
所述第二载波为所述终端进行PUCCH载波切换后传输PUCCH的载波。即所述第二载波为可以通过PUCCH载波切换进行PUCCH传输的载波。具体地,所述终端被配置或允许在所述第一载波和所述第二载波之间进行PUCCH切换。网络侧设备根据所述第一时间单元,确定载波切换后所述第二载波上传输PUCCH的第二时间单元,从而可以在载波切换后,在所述第二载波的第二时间单元接收PUCCH。
在一种实施例中,是从第一载波切换到第二载波,也就是通常情况下PUCCH是在第一载波传输,当满足切换条件需要进行载波切换时,从第一载波切换到第二载波上传输PUCCH。
步骤93、所述网络侧设备在所述第二载波的第二时间单元中接收终端发送的PUCCH。
网络侧设备基于第一载波上确定的进行PUCCH传输的第一时间单元,确定出第二载波上进行PUCCH传输的第二时间单元后,利用所述第二载波的第二时间单元接收PUCCH,完成PUCCH载波切换后的PUCCH传输。在该情况下,终端在所述第一载波的第一时间单元不再发送PUCCH,则所述网络侧设备在所述第一载波的第一时间单元不再接收PUCCH,PUCCH的发送行为和接收行为切换到第二载波的第二时间单元上进行。
在第一载波上需要传输PUCCH的第一时间单元中,如果确定需要进行 PUCCH载波切换,则可以根据预定规则确定PUCCH载波切换之后的目标载波为第二载波,根据所述第一载波上的第一时间单元,确定第二载波上的第二时间单元,并在第二载波的第二时间单元中接收PUCCH。其中,所述第二载波的第二时间单元中传输的PUCCH承载的信息为进行PUCCH载波切换之前需要在第一载波的第一时间单元中传输的PUCCH上的UCI(也可以仅是其中的部分信息),则在PUCCH载波切换后,无需在第一载波的第一时间单元中进行PUCCH传输,进而实现PUCCH从一个载波切换到另一个载波上传输。
需要说明的是,切换到第二载波的第二时间单元进行传输的PUCCH,在第二载波的第二时间单元中的具体传输PUCCH的时域资源(例如在第二时间单元中占用的具体符号位置和数量)和频域资源(例如RB个数和位置等,还可以包含码域资源,例如正交序列,循环移位等参数)可以按照其他的规则确定,在此不做限定。
本公开的实施例,在需要进行PUCCH载波切换时,基于PUCCH载波切换前的第一载波上确定的进行PUCCH传输的第一时间单元,确定切换后的第二载波上进行PUCCH传输的第二时间单元,从而在不需要额外信令通知或指示的基础上,确定出PUCCH载波切换后的载波上传输PUCCH的时间单元,能够保证PUCCH载波切换传输的正常实现,同时不增加额外信令开销。
所述终端配配置或允许在所述第一载波和所述第二载波之间进行PUCCH载波切换,则在载波切换后,所述网络侧设备接收PUCCH的位置发生变化,例如:终端由在第一载波的第一时间单元传输PUCCH,切换为在第二载波的第二时间单元传输PUCCH,则网络侧设备由原本的在第一载波的第一时间单元接收PUCCH切换为在第二载波的第二时间单元接收PUCCH。
具体地,所述根据所述第一时间单元,确定在第二载波上进行PUCCH传输的第二时间单元,可以包括以下其中一项:
方式(1):确定所述第二载波上与所述第一时间单元重叠的时间单元,为所述第二时间单元;
方式(2):确定所述第二载波上与所述第一时间单元重叠的时间单元中的目标时间单元,为所述第二时间单元。
所述第二时间单元可以为与所述第一载波上的第一时间单元重叠的时间单元中的特定的一个时间单元,例如:在第一载波的SCS更小或第一载波上的PUCCH传输时间单元更大的情况,可能存在一个第一时间单元与多个第二时间单元重叠,此时可以将多个所述第二时间单元中的一个特定的时间单元(即所述目标时间单元)作为PUCCH载波切换后的第二载波上进行PUCCH传输的时间单元。
具体地,所述目标时间单元可以包括以下其中一项:
与所述第一时间单元重叠的时间单元中的第一个时间单元;
与所述第一时间单元重叠的时间单元中的最后一个时间单元;
与所述第一时间单元重叠的时间单元中,包含可用PUCCH资源的第一个时间单元;
与所述第一时间单元重叠的时间单元中,包含可用PUCCH资源的最后一个时间单元;

其中,所述可用PUCCH资源为满足第一条件的PUCCH资源;

与所述第二载波上的高层信令配置的上行传输在频域上不重叠;
满足PUCCH承载的信息的准备时间需求。
所述满足PUCCH承载的信息的准备时间需求的PUCCH资源,例如,在PUCCH上传输的是HARQ-ACK时,需要在PUCCH上进行HARQ-ACK的下行传输的结束位置与PUCCH的起始位置之间满足固定的时间间隔,所述时间间隔是PDSCH处理以及准备在PUCCH上传输HARQ-ACK所需要的时间。
例如定义为:T proc,1=((N 1+d 1,1+d 1,2)(2048+144)·κ2 )·T c,其中N 1是与需要进行HARQ-ACK反馈的PDSCH的处理能力相关的处理时间,根据参考μ在处理能力列表中选择一个数值,κ为LTE采用间隔与NR采样间隔之间的比值,μ为SCS的索引,参考μ是调度PDSCH的PDCCH、PDSCH本身、PUCCH本身等对应的μ的最小值,T C为NR采用间隔,d 1,1为不同上行信道上传输HARQ-ACK的处理时间偏移值,如果在PUCCH上传输d 1,1=0,如果在PUSCH上传输d 1,1=1,d 1,2为与PDSCH所占用的符号数有关的处理时间偏移。
方式(3):根据需要进行载波切换的PUCCH对应的下行控制信息DCI的第一指示域的指示信息,确定所述第二时间单元;
具体地,所述第一指示域的指示信息,可以包括以下其中一项:
所述第二时间单元的信息;
相对于所述第一载波上的PUCCH的时域位置的时域偏移;
相对于所述第一载波上的所述第一时间单元的时域偏移。
该实施例中,对于具有对应的DCI的PUCCH,在进行PUCCH载波切换时,可以基于DCI中的一个第一指示域来确定在第二载波上传输PUCCH的第二时间单元,所述第一指示域可以是所述DCI中所包含的现有指示域的重 用或者是新增的指示域。所述第一指示域用来指示一个第二载波上的第二时间单元,或者指示相对于所述第一载波上的PUCCH的时域位置的时域偏移,或者指示相对于所述第一载波上的第一时间单元的时域偏移。所述时域偏移的单位可以是符号或者PUCCH传输时间单元,符号或PUCCH传输时间单元的单位为第二载波对应的单位。
方式(4):根据所述第一时间单元的预配置信息,确定所述第二时间单元。
具体地,所述第一时间单元的预配置信息,包括以下其中一项:
所述第二时间单元的信息;
相对于所述第一载波上的PUCCH的时域位置的时域偏移;
相对于所述第一载波上的所述第一时间单元的时域偏移。
该实施例中,可以对第一载波上的每个可以进行PUCCH切换的第一时间单元预先定义或预先配置一个第二载波上对应的第二时间单元,或者预先定义或预先配置一个时域偏移值,该时域偏移值用来指示第二载波上的PUCCH相对于第一载波上的PUCCH的时域位置的时域偏移,或者指示相对于所述第一时间单元的时域偏移。所述时域偏移的单位可以是符号或者PUCCH传输时间单元,符号或PUCCH传输时间单元的单位为第二载波对应的单位。
可选地,所述第二载波的子载波间隔SCS大于或者等于所述第一载波的SCS。所述第一载波和所述第二载波的SCS相同;或者,所述第一载波的SCS不大于所述第二载波的SCS。例如:所述第二载波的SCS为15kHz,则所述第一载波的SCS也为15kHz;又例如:所述第二载波的SCS为30kHz,所述第一载波的SCS可以为15kHz或30kHz等。
可选地,所述第一时间单元的单位与所述第二时间单元的单位相同,例如所述第一时间单元和所述第二时间单元的单位都是时隙,或都是相同长度的子时隙;或者,所述第一时间单元的单位与所述第二时间单元的单位不同,例如所述第一时间单元包含的符号数,小于或者等于所述第二时间单元包含的符号数。例如:所述第一载波上的PUCCH传输时间单元为时隙,则第二载波上的PUCCH传输时间单元也为时隙;第一载波上的PUCCH传输时间单 元为长度是7符号的子时隙,则第二载波上的PUCCH传输时间单元可以为时隙或长度是7符号的子时隙,但不能是长度是2符号的子时隙。
该实施例中,传输时间单元的单位可以是时隙、子时隙中的一种,子时隙可以有不同的长度,如2符号子时隙或者7符号子时隙。如果第二载波上没有配置PUCCH传输时间单元的单位,则确定按照与第一载波上相同的PUCCH传输时间单元或者预先约定的PUCCH传输时间单元进行传输。
本公开应用于网络侧设备的所述PUCCH传输方法的实现过程,与应用于终端的PUCCH传输方法的实现过程相同或者相似,参见示例一至示例四,在此不做赘述。需要说明的是,示例一至示例四仅以确定第二时间单元的方式(1)和方式(2)为例进行说明,需要说明的是,还可以根据方式(3)和方式(4)确定在第二载波上进行PUCCH传输的第二时间单元,例如:根据需要进行载波切换的PUCCH对应的DCI中的第一指示域的指示,确定所述第二时间单元,或者根据预定义或者预配置的信息确定所述第二时间单元。具体地,可以通过方式(3)或方式(4)直接确定在第二载波上传输PUCCH的第二时间单元,或者根据方式(3)或方式(4)中的方式确定一个偏移值,基于该偏移值以及第一时间单元,来确定第二载波上的第二时间单元。
本公开的实施例以不同载波之间为同步CA的情况为例进行说明,即不同载波上的无线帧的边界为对齐的,则不同载波在相同的SCS情况下的时隙边界也是对齐的;需要说明的是,还也可以应用于非同步CA的情况,即不同载波之间的时隙编号相差一个固定的offset,此时差别在于在相同的SCS的情况下,与第一载波上的时隙n对齐的第二载波上的并不一定是时隙n,可能是时隙m,m=n+offset,offset的单位是时隙,如果子载波间隔不同,offset会以一个参考SCS对应的时隙个数来体现。在这种情况下,使用本公开实施例的方式,依然可以确定出第二载波上对应的第二时间单元。
本公开实施例的PUCCH传输方法中,根据第一时间单元,确定在第二载波上进行PUCCH传输的第二时间单元的具方法,适用于终端和网络侧设备,即终端确定所述第二载波上进行PUCCH传输的第二时间单元的方法,同样适用于网络侧设备确定所述第二载波上进行PUCCH传输的第二时间单元的实施例中,重复内容不做赘述。在本公开实施例的PUCCH传输方法中, 对于终端,在确定了第二载波上的第二时间单元之后,在第二时间单元中发送PUCCH;对于网络侧设备,在确定了第二载波上的第二时间单元之后,在第二时间单元中接收PUCCH。
