  • T1mux is related to the processing delay of the PDSCH, and can be calculated according to a predetermined formula and related parameters. The purpose of this timeline is to ensure that the acquisition and preparation of the HARQ-ACK can be completed before the transmission of the finally determined channel for transmitting the HARQ-ACK starts.
  • Timeline2 The target symbol is not earlier than the first symbol after the T2mux time after the last symbol of any PDCCH (including the PDCCH requiring HARQ-ACK feedback) that schedules PDSCH (if any) and PUSCH (if any) (including CP included), that is, the time interval between the target symbol and the last symbol of any one of the above PDCCHs is not less than T2mux time.

If the PUCCH overlaps with the repeated transmission of the PUSCH, when the PUSCH uses slot-based repeated transmission (R15 repeated transmission, or R16 repetition type A), the UCI carried by the PUCCH is transferred to one or more PUSCH slots that overlap with the PUCCH.

第五代新无线系统(5 Generation New RAT,5G NR)系统版本16(Release-16,Rel-16,R16)中,考虑到实现复杂度,当具有不同优先级的上行信道存在时域资源重叠(即冲突)时,总是丢弃低优先级的信道,只传输高优先级的信道。为了避免丢弃低优先级的信道上承载的HARQ-ACK带来的下行重传问题,第三代合作伙伴计划(3rd Generation Partnership Project,3GPP)标准会议讨论可以支持具有不同优先级的上行信道进行复用传输。
在处理具有不同优先级的上行信道的冲突时,会存在具有不同优先级的PUCCH和PUSCH的冲突且不支持PUCCH和PUSCH的并行传输的情况,此时如何提供一种UCI传输方案,是业界亟需解决的重要课题。
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公开一部分实施例,并不是全部的实施例。基于本公开中的实施例,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,都属于本公开保护的范围。
为了便于更加清晰地理解本公开各实施例,首先对本公开各实施例相关的一些技术内容进行介绍。
(1)5G NR中的UCI传输
UCI包含HARQ-ACK,CSI,SR等信息,UCI可以在PUCCH和PUSCH上传输。其中,HARQ-ACK是ACK和NACK的统称,用于针对物理下行共享信道(Physical Downlink Shared Channel,PDSCH)或需要进行HARQ-ACK反馈的物理下行控制信道(Physical Downlink Control Channel,PDCCH)(如 指示半持续调度(Semi-Persistent Scheduling,SPS)资源释放的PDCCH(又称SPS PDSCH release),指示辅小区休眠(SCell dormancy)的PDCCH)进行反馈,告知基站PDSCH或需要进行HARQ-ACK反馈的PDCCH是否正确接收;CSI用于反馈下行传输的信道质量,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,向基站请求分配PUSCH传输资源,来进行上行业务传输。
HARQ-ACK可以基于不同的时间单元进行反馈,时间单元可以是时隙(slot)或子时隙(sub-slot)。子时隙是按照预定的子时隙长度将一个时隙固定划分为多个子单元,例如,一个子时隙长度为7个符号,可将一个包含14个符号的时隙划分为2个子时隙,又例如,一个子时隙长度为2个符号,可将一个包含14个符号的时隙划分为7个子时隙。当基于时隙进行反馈时,按照反馈时序n+k1确定承载HARQ-ACK的PUCCH传输所在时隙,其中,n为与需要进行HARQ-ACK反馈的下行传输(包括PDSCH和需要进行HARQ-ACK反馈的PDCCH)所在的时隙对应的参考上行时隙,k1为参考上行时隙与传输HARQ-ACK的目标时隙之间的时隙偏移值(即k1的单位是时隙);当基于子时隙进行反馈时,按照反馈时序n+k1确定承载HARQ-ACK的PUCCH传输所在子时隙,其中,n为与需要进行HARQ-ACK反馈的下行传输(包括PDSCH和需要进行HARQ-ACK反馈的PDCCH)所在的时隙对应的参考上行子时隙,k1为参考上行子时隙与传输HARQ-ACK的目标子时隙之间的子时隙偏移值(即k1的单位是子时隙)。承载HARQ-ACK的PUCCH资源不会跨越HARQ-ACK反馈所使用的时间单元,即如果基于子时隙传输,则承载HARQ-ACK的PUCCH不会超过子时隙边界,即不会跨域在多个子时隙中传输。
(2)相同优先级的PUCCH与PUCCH/PUSCH重叠
NR Rel-16中不支持PUCCH与PUSCH在同一时刻并行传输,不管是同一个载波还是不同载波上。当PUCCH和PUSCH(不做特殊说明,一般PUCCH 和PUSCH指不使用重复传输的PUCCH和PUSCH)在时域资源上存在重叠时,在满足预定的时间线(timeline)的情况下,可以将UCI(一般是HARQ-ACK和CSI)从PUCCH上转移到一个PUSCH上传输,如果存在SR,则SR不在PUSCH上传输,SR被丢弃。如果存在多个PUSCH都与PUCCH重叠,则按照下述规则选择一个PUSCH,其中:优先选择承载非周期信道状态信息(Aperiodic CSI,A-CSI)的PUSCH,如果同时存在具有PDCCH调度的PUSCH(动态授权PUSCH(Dynamic Granted-PUSCH,DG PUSCH))和没有PDCCH调度的PUSCH(配置授权PUSCH(Configured Granted--PUSCH,CG PUSCH),半持续信道状态信息(semi-persistent CSI,SP-CSI)PUSCH等),优先选择DG PUSCH,按照上述规则选择之后,如果多个载波上都有PUSCH,优先选择载波编号低的载波上的PUSCH,如果选择的载波上存在多个时域上不重叠的PUSCH与PUCCH重叠,选择最早的PUSCH。
其中,timeline的定义为:如果PUCCH或PUSCH具有对应的PDCCH时,例如PUCCH承载的HARQ-ACK为具有PDCCH调度的PDSCH的HARQ-ACK或为指示下行SPS资源释放的PDCCH的HARQ-ACK,则该调度PDSCH的PDCCH或指示下行SPS资源释放的PDCCH为PUCCH对应的PDCCH,或者也可以称为调度PUCCH的PDCCH,调度PUSCH的PDCCH则为PUSCH对应的PDCCH,将重叠的PUCCH和PUSCH中的起始时间最早的信道的第一个符号作为目标符号,如果存在多个起始时刻相同的信道,则随便选一个信道,将其第一个符号作目标符号,目标符号需要满足如下timeline才能进行复用传输,否则认为是错误调度:
Timeline1:目标符号不早于在任何一个需要在PUCCH上进行HARQ-ACK反馈的PDSCH或SPS PDSCH release的最后一个符号之后的T1mux时间之后的第一个符号(包括循环前缀(Cyclic Prefix,CP)在内的),即目标符号与任何一个上述PDSCH或SPS PDSCH release的最后一个符号之间的时间间隔不少于T1mux时间。T1mux与PDSCH的处理时延有关,可以根据预定的公式和相关的参数计算得到。该timeline的目的是保证在最终确定的传输HARQ-ACK的信道的传输开始之前,能够完成对HARQ-ACK的获 取和准备。
Timeline2:目标符号不早于调度PDSCH(如果有)和PUSCH(如果有)的任意一个PDCCH(包括需要进行HARQ-ACK反馈的PDCCH)的最后一个符号之后的T2mux时间之后的第一个符号(包括CP在内的),即目标符号与任何一个上述PDCCH的最后一个符号之间的时间间隔不少于T2mux时间。T2mux与PUSCH的处理时延有关,可以根据预定的公式和相关的参数计算得到。该timeline的目的是保证当UCI需要转移到PUSCH上传输时,能够在PUCCH开始准备之前获得调度PUSCH的PDCCH,从而确定不需要在PUCCH上准备UCI传输,并且能够在PUSCH传输之前完成包括UCI在内的传输准备,即完成UCI的获取和复用处理,完成传输块(Transport Block,TB)的准备(如编码,调制,加扰等操作);如果是多个PUCCH之间的复用,这个T2mux是用来模拟CSI和SR与HARQ-ACK复用的准备时间的。
如果PUCCH承载的HARQ-ACK没有对应的PDCCH(即HARQ-ACK为SPS PDSCH的HARQ-ACK),此时没有调度PDSCH的PDCCH,如果没有PUSCH或PUSCH也没有对应的PDCCH,则仅需要check T1mux不需要check T2mux。如果PUCCH上承载的是CSI和/或SR,因为没有对应的PDSCH,则不需要check T1mux,进一步如果没有PUSCH或PUSCH没有对应的PDCCH,则也不需要check T2mux。
如果PUCCH和PUCCH重叠时,至少一个PUCCH是重复传输的(即占用多个时隙在每个时隙中重复性的传输UCI,也称多时隙传输),则仅针对重叠的repetition,按照传输高优先级,丢弃低优先级处理,不影响不存在重叠的repetition。如果PUCCH和重复传输的PUSCH重叠,当PUSCH采用基于时隙的重复传输时(R15重复传输,或R16 repetition type A),PUCCH承载的UCI转移到和PUCCH重叠的一个或者多个PUSCH时隙中进行传输;当PUSCH采用R16 repetition type B时,PUCCH承载的UCI转移到和PUCCH重叠的最早的一个包含大于1个符号的actual repetition PUSCH中传输(actual repetition即根据不可用符号、下行(Downlink,DL)符号、时隙边界等进行分段之后得到的repetition PUSCH);上述与PUCCH重叠的一个或多个 repetition的PUSCH都需要满足复用timeline。如果使用重复传输的PUCCH与使用或不使用重复传输的PUSCH重叠,则丢弃与PUCCH重叠的PUSCH,保证PUCCH的重复传输不被打断。
R17中根据终端(也称用户设备(User Equipment,UE))能力可以支持inter-band载波聚合(Carrier Aggregation,CA)情况下不同载波上的PUCCH和PUSCH并行传输,但同一个载波上以及intra-band CA情况下暂不支持并行传输。
(3)不同物理层优先级的信道传输
一个UE可以支持不同的业务类型,如增强移动宽带(enhanced Mobile Broadband,eMBB)业务和低时延高可靠通信(Ultra-Reliable and Low Latency Communication,URLLC)业务等。不同的业务类型对可靠性和传输时延的需求不同。URLLC业务流可能是零散的不定时发生的,因此针对不同的业务独立预留不同的系统资源,在系统资源上的开销比较大,可能很多时候为URLLC预留的资源都是没有被使用的。为了提高系统资源利用率,可以支持不同业务在相同资源上复用传输。为了避免业务之间的相互影响,可以对不同的业务定义不同的优先级,从而在出现资源冲突的时候,区分哪些信道和信息更为重要。
PUCCH、PUSCH的物理层优先级可以通过默认方式、下行控制信息(Downlink Control Information,DCI)动态指示或者无线资源控制(Radio Resource Control,RRC)半静态配置的方式获得。例如,PUCCH在承载SR时,其优先级是通过其承载的SR对应的优先级确定的,而每个SR配置对应的优先级是高层信令配置的;PUCCH在承载SPS PDSCH的HARQ-ACK或承载指示SPS资源释放的PDCCH(即SPS PDSCH release)的HARQ-ACK时,其优先级是通过高层信令为SPS PDSCH配置的HARQ-ACK码本编号来确定的,对应编号为0的HARQ-ACK码本为低优先级,对应编号为1的HARQ-ACK码本为高优先级;PUCCH在承载CSI(包括周期CSI和SP-CSI)时,其优先级默认为低优先级。当DCI中包含优先级指示域时,可以通过PUCCH、PUSCH对应的DCI(或PDCCH,本公开中PDCCH和DCI可以认 为等价,DCI是PDCCH传输使用的具体格式,则具有对应的DCI等价于具有对应的PDCCH)中的优先级指示域获得优先级,即动态的优先级指示方式,例如,PDCCH调度一个PDSCH时,可以通过优先级指示域指示承载这个PDSCH的HARQ-ACK的PUCCH的优先级;PDCCH调度一个PUSCH时,可以通过优先级指示域指示被调度的PUSCH的优先级,其中,PUSCH包括仅承载TB的PUSCH或仅承载A-CSI的PUSCH或同时承载TB和A-CSI的PUSCH;对于承载SP-CSI的PUSCH,其优先级可以通过激活承载SP-CSI的PUSCH的DCI中的优先级指示域获得。如果DCI中不包含优先级指示域,或高层信令没有配置优先级,则默认为低优先级。
Rel-16中考虑到实现复杂度,并不支持具有不同物理层优先级的上行信道之间进行复用传输。当具有不同物理层优先级的上行信道发生冲突时,即多个PUCCH在同一个载波上在时域上存在重叠,或PUCCH和PUSCH在同一个载波或不同载波上在时域上存在重叠,或多个PUSCH在同一个载波上在时域上存在重叠时,丢弃低优先级的上行信道,只传输高优先级的上行信道。考虑到基于优先级的比较来停止低优先级的上行信道的发送需要一定的额外处理时间,进一步定义了停止低优先级上行信道的timeline:要求对应高优先级的上行信道的PDCCH与高优先级上行信道的起始符号之间的时间间隔不小于一个预定的T时间,这个T时间中考虑了原处理时延(例如T1proce、T2proce)和停止所需的额外时间(d1)。其中,T1proce实际上指的是协议中定义的T1,T1是协议中定义的PDSCH的处理时间(包括PDSCH接收译码等处理,以及相关HARQ-ACK反馈的准备时间等),T2proce实际上指的是协议中定义的T2,T2是协议中定义的PUSCH的处理时间(包括PUSCH的准备时间等)。
Rel-17中,考虑到总是丢弃低优先级上行信道带来的系统效率下降的影响,例如总是丢弃低优先级HARQ-ACK,会导致低优先级HARQ-ACK对应的下行传输因无法及时获得反馈信息而进行冗余的重传,考虑支持具有不同物理层优先级的上行信道之间进行复用传输。
当存在多个具有不同优先级的上行信道之间的冲突时,一种可能的方式 为按照下述步骤处理:
步骤1、先解决同一种优先级的上行信道之间的冲突,包括PUCCH之间以及PUCCH和PUSCH之间的冲突。例如,对于低优先级的PUCCH,可以按照现有技术规定的PUCCH之间的复用传输方案,找到一个PUCCH资源同时承载多个存在冲突的PUCCH上的UCI,或在不支持复用传输时丢弃某种UCI来解决冲突,从而得到一个或多个相互不重叠的低优先级的PUCCH,如果PUCCH存在与PUSCH的冲突且不支持PUCCH和PUSCH并行传输,则需要确定一个PUSCH承载与之冲突的PUCCH上的UCI,从而不传输这个PUCCH,最终得到一个或多个相互不重叠的低优先级的PUCCH/PUSCH;同理,对于高优先级的PUCCH,可以按照现有技术规定的PUCCH之间的复用传输方案,找到一个PUCCH资源同时承载多个存在冲突的PUCCH上的UCI,或在不支持复用传输时丢弃某种UCI来解决冲突,从而得到一个或多个相互不重叠的高优先级的PUCCH,如果PUCCH存在与PUSCH的冲突且不支持PUCCH和PUSCH并行传输,则需要确定一个PUSCH承载与之冲突的PUCCH上的UCI,从而不传输这个PUCCH,最终得到一个或多个相互不重叠的高优先级的PUCCH/PUSCH。
步骤2、由于高优先级和低优先级的上行信道之间还可能存在重叠,则需要进一步解决具有不同优先级的上行信道之间的冲突问题;分为步骤2-1和步骤2-2:
步骤2-1、先解决具有不同优先级的PUCCH之间的冲突;可以按照预定的不同优先级之间的复用传输方案(包括在同一个信道上传输或不支持复用时丢弃某种UCI的规则),得到一个或多个相互不重叠的PUCCH(可能一些是低优先级的,一些是高优先级的,也可能都是某一种优先级的);
步骤2-2、如果还存在PUSCH与这些得到的PUCCH存在重叠且不支持PUCCH和PUSCH并行传输,则需要进一步解决PUCCH和PUSCH之间的冲突,此时PUCCH和PUSCH可能具有相同的优先级也可能具有不同的优先级,这是因为虽然步骤1中已经解决了相同优先级的PUCCH和PUSCH之间的冲突,但经过步骤2-1的不同优先级的PUCCH复用过程,根据复用在同一 个信道上传输的高、低优先级的UCI的总比特数,可能会确定出一个新的高优先级UCI对应的PUCCH资源,新PUCCH资源可能与PUSCH之间存在冲突,因此需要进行PUCCH和PUSCH之间的复用传输,以解决PUCCH和PUSCH的冲突。
此外,是否支持具有不同优先级的信道之间进行复用传输可以是基于高层信令的半静态配置来开启或关闭此功能,也可以是通过PDCCH中的动态指示来开始或关闭此功能,PDCCH可以是调度下行传输的PDCCH,自身需要进行HARQ-ACK反馈的PDCCH,调度PUSCH的PDCCH等。
图1为本公开实施例提供的上行控制信息UCI传输方法的流程示意图之一,该方法应用于终端,如图1所示,该方法包括如下步骤:
步骤100、在承载第一UCI的物理上行控制信道PUCCH的时域资源与多个物理上行共享信道PUSCH的时域资源存在重叠,且多个PUSCH中包括承载第二UCI的PUSCH的情况下,从多个PUSCH中优先选择没有承载第二UCI的PUSCH,将第一UCI转移到所选择的没有承载第二UCI的PUSCH上传输;或者,从多个PUSCH中选择用于承载第一UCI的目标PUSCH,并根据目标PUSCH承载的UCI信息,确定相应的UCI传输方式;
其中,PUCCH和承载第二UCI的PUSCH具有不同的优先级,或者第一UCI中包含第一优先级的UCI,第二UCI中包含第二优先级的UCI。需要说明的是,实施例中所述根据目标PUSCH承载的UCI信息,确定相应的UCI传输方式,不限于根据目标PUSCH承载的UCI信息,也可以包括根据其它信息或目标PUSCH承载的UCI信息与其它信息的组合,确定相应的UCI传输方式。
在一些实施例中,该方法包括:
在承载第一UCI的物理上行控制信道PUCCH的时域资源与多个物理上行共享信道PUSCH的时域资源存在重叠,且多个PUSCH中包括承载第二UCI的PUSCH的情况下,从多个PUSCH中优先选择没有承载第二UCI的PUSCH,在所选择的没有承载第二UCI的PUSCH上传输第一UCI;或者,从多个PUSCH中选择用于承载第一UCI的目标PUSCH,并根据目标PUSCH 承载的UCI信息,确定相应的UCI传输方式;
其中,PUCCH和承载第二UCI的PUSCH具有不同的优先级,或者第一UCI中包含第一优先级的UCI,第二UCI中包含第二优先级的UCI。
具体地,第一UCI指的是PUCCH上承载的UCI,第一UCI可以是一个或多个UCI,当第一UCI为多个时,第一UCI可以理解为PUCCH上承载的UCI的集合。或者,第一UCI也可以指PUCCH上承载的某一种特定的UCI,例如HARQ-ACK,如果PUCCH上还同时承载了其他UCI,例如SR,第一UCI可以不包含其他UCI,以第一UCI为HARQ-ACK为例,则仅承载HARQ-ACK的PUCCH,与同时承载HARQ-ACK和SR的PUCCH都称之为承载第一UCI的PUCCH。
与PUCCH存在时域资源重叠的多个PUSCH中包括承载第二UCI的PUSCH,第二UCI可以是一个或多个UCI,当第二UCI为多个时,第二UCI可以理解为承载第二UCI的PUSCH上承载的UCI的集合。或者,第二UCI也可以指PUSCH上承载的某一种特定的UCI,例如CSI,如果PUSCH上还同时承载了其他UCI,例如HARQ-ACK,第二UCI可以不包含其他UCI,以第二UCI为CSI为例,则仅承载CSI的PUSCH,与同时承载HARQ-ACK和CSI的PUSCH都称之为承载第二UCI的PUSCH。
第一UCI中包含第一优先级的UCI,第二UCI中包含第二优先级的UCI,可以理解为第一UCI中包含的某一种UCI与第二UCI中包含的某一种UCI具有不同的优先级。第一优先级和第二优先级表示不同的优先级,如第一优先级为高优先级,第二优先级为低优先级;或者,第一优先级为低优先级,第二优先级为高优先级,在此并不对第一优先级和第二优先级的具体类型做限制,只要第一优先级和第二优先级不同即可。
例如,第一UCI为高优先级的HARQ-ACK,第二UCI为低优先级的HARQ-ACK、低优先级的CSI中的一个或组合;或者,第一UCI为低优先级的HARQ-ACK、低优先级的CSI中的一个或组合,第二UCI为高优先级的HARQ-ACK、高优先级的CSI中的一个或组合;或者,第一UCI为高优先级的HARQ-ACK+低优先级的HARQ-ACK时,第二UCI为高优先级的CSI或 低优先级的CSI中的一个或组合都是符合条件的。
可选地,可以是第一UCI至少包含高优先级的UCI,第二UCI至少包含低优先级的UCI;或者,也可以是第一UCI至少包含低优先级的UCI,第二UCI至少包含高优先级的UCI。
第一UCI至少包含高优先级的UCI,第二UCI至少包含低优先级的UCI的情形举例如下:
例如,第一UCI为高优先级的HARQ-ACK,第二UCI为低优先级的CSI(如原本配置在PUCCH上传输的周期CSI、SP-CSI等认为是低优先级CSI,如果CSI本身是在PUSCH上传输的,如PUSCH上传输的A-CSI、SP-CSI,其优先级是可以根据触发A-CSI或SP-CSI的PDCCH中的优先级指示域指示所得到的,可以是高优先级或低优先级);
例如,第一UCI为高优先级的HARQ-ACK,第二UCI包含低优先级的HARQ-ACK和低优先级的CSI;
例如,第一UCI包含高优先级的HARQ-ACK和低优先级的HARQ-ACK,第二UCI为低优先级的CSI。
第一UCI至少包含低优先级的UCI,第二UCI至少包含高优先级的UCI的情形举例如下:
例如,第一UCI为低优先级的HARQ-ACK,第二UCI为高优先级的CSI;
例如,第一UCI为低优先级的HARQ-ACK,第二UCI包含高优先级的HARQ-ACK和高优先级的CSI;
例如,第一UCI包含低优先级的HARQ-ACK和高优先级的HARQ-ACK,第二UCI为高优先级的CSI;
例如,第一UCI包含低优先级的HARQ-ACK和低优先级的CSI,第二UCI为高优先级的CSI;
例如,第一UCI包含低优先级的HARQ-ACK和低优先级的CSI,第二UCI包含高优先级的HARQ-ACK和高优先级的CSI;
例如,第一UCI为低优先级的CSI,第二UCI包括高优先级的HARQ-ACK、高优先级的CSI中的至少一种。
可选地,上述第一UCI和第二UCI满足以下任一条件或组合条件:
第一UCI包含的UCI和第二UCI包含的UCI中存在不支持复用传输的UCI,这可以理解为第一UCI中包含的某一种UCI与第二UCI中包含的某一种UCI不支持复用传输,例如假设不支持具有不同优先级的HARQ-ACK和CSI复用传输,第一UCI中包含高优先级的HARQ-ACK,第二UCI中包含低优先级的CSI,则符合该条件;或者,
第一UCI包括HARQ-ACK和/或CSI中的一种或多种,第二UCI包括HARQ-ACK和/或CSI中的一种或多种。
在承载第一UCI的PUCCH和多个PUSCH存在时域资源重叠,且该多个PUSCH中包括存在承载第二UCI的PUSCH的情况下,本公开实施例提供一种UCI传输的解决方案,包括方法一和方法二。
方法一:从该多个PUSCH中优先选择没有承载第二UCI的PUSCH,在选择出一个没有承载第二UCI的PUSCH后,将PUCCH上承载的第一UCI转移到所选出的没有承载第二UCI的PUSCH上传输,也就是说,在所选出的没有承载第二UCI的PUSCH上传输第一UCI,在承载第二UCI的PUSCH上不传输第一UCI,且不传输原本承载该第一UCI的PUCCH,从而避免了PUCCH和PUSCH的并行传输;“转移”的意思即将原本在PUCCH上传输的UCI放在PUSCH上传输,而不再传输PUCCH的行为。其中,如果第一UCI包含了多种UCI,不排除因为不支持某种UCI在PUSCH上传输,或不支持第一UCI中的某种UCI与PUSCH上承载的某种UCI同时传输,而丢弃第一UCI中部分UCI,仅转移可以在PUSCH上传输的那部分UCI到PUSCH上传输。
方法二:从该多个PUSCH中选择一个目标PUSCH,该目标PUSCH将可能用于承载第一UCI,在选择出目标PUSCH后,根据目标PUSCH承载的UCI信息,确定相应的UCI传输方式,也就是说,在选择出目标PUSCH后,可以根据该目标PUSCH上本身承载的UCI,来确定相应的UCI传输方式。
其中,方法二中选择目标PUSCH,可以按照现有技术中的规则进行,或现有技术中的规则与是否支持不同优先级复用传输、优先级等的组合进行(具 体结合的顺序可以是任意一种预定义的形式,例如将根据优先级选择PUSCH的规则增加到上述选择步骤中的任何一步的前面或后面都可以),在此不做具体限制。即方法二中选择目标PUSCH并不考虑PUSCH上承载的UCI是否能支持与第一UCI的同时传输。其中,现有技术中的规则可以是根据是否承载A-CSI、PUSCH所在载波的载波编号、PUSCH是否具有对应的PDCCH、PUSCH起始位置的组合规则进行选择,例如优先选择承载A-CSI的PUSCH,在没有承载A-CSI的PUSCH时,如果同时存在具有PDCCH调度的PUSCH(DG PUSCH)和没有PDCCH调度的PUSCH(CG PUSCH,SP-CSI PUSCH等),优先选择DG PUSCH,按照上述规则选择之后,如果多个载波上都有PUSCH,优先选择载波编号低的载波上的PUSCH,如果选择的载波上存在多个时域上不重叠的PUSCH与PUCCH重叠,选择最早的PUSCH。
本公开实施例提供的上行控制信息UCI传输方法,终端可以在承载第一UCI的PUCCH和多个PUSCH存在时域资源重叠,且该多个PUSCH中包括存在承载第二UCI的PUSCH的情况下,从该多个PUSCH中优先选择没有承载第二UCI的PUSCH,然后在所选择的没有承载第二UCI的PUSCH上传输第一UCI,避免了不同优先级UCI在同一PUSCH上传输可能导致无法正常传输的问题;或者,根据从该多个PUSCH中选择的目标PUSCH上承载的UCI信息,来确定相应的传输方式,从而针对相关场景没有明确的传输方案的问题,给出具体的UCI传输方法,保证系统的正常工作。
可选地,在方法一中,优先选择没有承载第二UCI的PUSCH进一步包括以下任意一种:
优先选择没有承载第二UCI的PUSCH,优先选择与PUCCH具有相同优先级的PUSCH两者的组合;或者,
优先选择没有承载第二UCI的PUSCH,优先选择支持不同优先级复用传输的PUSCH两者的组合;或者,
优先选择没有承载第二UCI的PUSCH,优先选择与PUCCH具有相同优先级的PUSCH,优先选择支持不同优先级复用传输的PUSCH三者的组合。
具体地,方法一中,优先选择没有承载第二UCI的PUSCH,可以是在与 PUCCH存在时域资源重叠的所有PUSCH中,先按照如下规则1或规则1与规则2、3中的一个或多个的组合进行选择,然后再根据现有技术中的规则进行选择,如根据是否承载A-CSI、PUSCH所在载波的载波编号、PUSCH是否具有对应的PDCCH、PUSCH起始位置的组合进行选择等。
规则1:选择没有承载第二UCI的PUSCH。
规则2:选择具有与PUCCH相同优先级的PUSCH。
规则3:选择支持不同优先级复用的PUSCH,其中优先级可以是指信道的优先级或UCI的优先级等,此处不做具体限制。
其中,进行选择时,采用规则1、规则2、规则3可以具有不同的顺序组合,例如,可以采用规则1+现有技术;规则1+规则2+现有技术;规则1+规则3+现有技术;规则1+规则2+规则3+现有技术;规则2+规则1+现有技术;规则3+规则1+现有技术;规则1+规则3+规则2+现有技术;规则2+规则1+规则3+现有技术;规则3+规则1+规则2+现有技术;规则2+规则3+规则1+现有技术;规则3+规则2+规则1+现有技术,等等。上述组合的书写顺序代表了使用规则的先后顺序。
例如,在与PUCCH存在时域资源重叠的所有PUSCH中,先选择没有承载第二UCI的PUSCH,再根据现有技术方式进行选择;
例如,在与PUCCH存在时域资源重叠的所有PUSCH中,先选择没有承载第二UCI的PUSCH,再选择具有与PUCCH相同优先级的PUSCH,再根据现有技术方式进行选择;
例如,在与PUCCH存在时域资源重叠的所有PUSCH中,先选择具有与PUCCH相同优先级的PUSCH,再选择没有承载第二UCI的PUSCH,再根据现有技术方式进行选择;
例如,在与PUCCH存在时域资源重叠的所有PUSCH中,先选择没有承载第二UCI的PUSCH,再选择支持不同优先级复用的PUSCH,再根据现有技术方式进行选择;
例如,在与PUCCH存在时域资源重叠的所有PUSCH中,先选择支持不同优先级复用的PUSCH,再选择没有承载第二UCI的PUSCH,再根据现有 技术方式进行选择;
例如,在与PUCCH存在时域资源重叠的所有PUSCH中,先选择没有承载第二UCI的PUSCH,再选择具有与PUCCH相同优先级的PUSCH,再选择支持不同优先级复用的PUSCH,再根据现有技术方式进行选择;
例如,在与PUCCH存在时域资源重叠的所有PUSCH中,先选择没有承载第二UCI的PUSCH,再选择支持不同优先级复用的PUSCH,再选择具有与PUCCH相同优先级的PUSCH,再根据现有技术方式进行选择;
例如,在与PUCCH存在时域资源重叠的所有PUSCH中,先选择支持不同优先级复用的PUSCH,再选择具有与PUCCH相同优先级的PUSCH,再选择没有承载第二UCI的PUSCH,再根据现有技术方式进行选择;
例如,在与PUCCH存在时域资源重叠的所有PUSCH中,先选择支持不同优先级复用的PUSCH,再选择没有承载第二UCI的PUSCH,再选择具有与PUCCH相同优先级的PUSCH,再根据现有技术方式进行选择;
例如,在与PUCCH存在时域资源重叠的所有PUSCH中,先选择具有与PUCCH相同优先级的PUSCH,再选择支持不同优先级复用的PUSCH,再选择没有承载第二UCI的PUSCH,再根据现有技术方式进行选择;
例如,在与PUCCH存在时域资源重叠的所有PUSCH中,先选择具有与PUCCH相同优先级的PUSCH,再选择没有承载第二UCI的PUSCH,再选择支持不同优先级复用的PUSCH,再根据现有技术方式进行选择。
通过上述方式选择出一个没有承载第二UCI的PUSCH后,便可以将PUCCH上承载的第一UCI转移到所选出的没有承载第二UCI的PUSCH上传输,从而避免了不同优先级UCI在同一PUSCH上传输可能导致无法正常传输的问题,保证了系统的正常工作。其中,可以网络设备(例如基站)和终端约定不会出现与PUCCH的时域资源存在重叠的PUSCH中都是承载第二UCI的PUSCH,即总是能选择出一个没有承载第二UCI的PUSCH;或者,如果允许出现与PUCCH的时域资源存在重叠的PUSCH中都是承载第二UCI的PUSCH,则可以重用方法二或者方法二中“在目标PUSCH为承载第二UCI的PUSCH的情况下”的任一项传输方式1-3,来解决PUCCH和PUSCH的 资源冲突。
可选地,在方法二中,根据目标PUSCH承载的UCI信息,确定相应的UCI传输方式,包括:
在目标PUSCH不为承载第二UCI的PUSCH的情况下,将第一UCI转移到目标PUSCH上传输;或者,
在目标PUSCH为承载第二UCI的PUSCH的情况下,根据以下任意一项进行传输:
丢弃第二UCI,将第一UCI转移到目标PUSCH中进行传输;或者,
丢弃第二UCI中的部分UCI,将第一UCI转移到目标PUSCH中,与第二UCI中剩余的UCI一起传输;或者,
丢弃第一UCI中的部分UCI,将第一UCI中剩余的UCI转移到目标PUSCH中,与第二UCI一起传输;或者,
将第一UCI转移到目标PUSCH中,与第二UCI一起传输;或者,
丢弃目标PUSCH或丢弃PUCCH。
在一些实施例中,根据目标PUSCH承载的UCI信息,确定相应的UCI传输方式,包括:
在目标PUSCH不为承载第二UCI的PUSCH的情况下,在目标PUSCH上传输第一UCI;或者,
在目标PUSCH为承载第二UCI的PUSCH的情况下,根据以下任意一项进行传输:
丢弃第二UCI,在目标PUSCH中传输第一UCI;或者,
丢弃第二UCI中的部分UCI,在目标PUSCH中传输第一UCI以及第二UCI中剩余的UCI;或者,
丢弃第一UCI中的部分UCI,在目标PUSCH中传输第一UCI中剩余的UCI以及第二UCI;或者,
在目标PUSCH中传输第一UCI以及第二UCI;或者,
丢弃目标PUSCH或丢弃PUCCH。
具体地,方法二中,从多个PUSCH中选择出目标PUSCH后,可以根据 该目标PUSCH承载的UCI信息,确定相应的UCI传输方式。
具体来说,在该目标PUSCH不是承载第二UCI的PUSCH的情况下,即该目标PUSCH没有承载第二UCI的情况下,则可以将第一UCI转移到该目标PUSCH上传输,这可以避免不同优先级UCI在同一PUSCH上传输可能导致无法正常传输的问题,保证了系统的正常工作。
在该目标PUSCH是承载第二UCI的PUSCH的情况下,即该目标PUSCH承载第二UCI的情况下,则可以采用以下任意一种方式进行传输。
方式1:丢弃第二UCI,将第一UCI转移到目标PUSCH中传输;或者,丢弃第二UCI中的部分UCI(例如不能与第一UCI复用传输的UCI),将第一UCI转移到目标PUSCH中与剩余的第二UCI一起传输;或者,丢弃第一UCI中的部分UCI(例如不能与第二UCI复用传输的UCI),将第一UCI的剩余内容转移到目标PUSCH中与第二UCI一起传输。
方式2:直接将第一UCI转移到目标PUSCH中,与第二UCI一起传输。
方式3:丢弃目标PUSCH,即不传输目标PUSCH,目标PUSCH上的信息(包括data和UCI)也随之被丢弃;或者,丢弃PUCCH,即不传输承载第一UCI的PUCCH,第一UCI也随着PUCCH被丢弃。
其中,“丢弃”的意思就是终端不再发送这个上行信道或UCI,相应的,网络设备不再接收这个上行信道或UCI。
可选地,丢弃目标PUSCH之后,该方法还包括:
丢弃其他所有与PUCCH之间存在时域资源重叠的PUSCH,传输承载第一UCI的PUCCH;或者,
从剩余的与PUCCH之间存在时域资源重叠的PUSCH中,选择新的用于承载第一UCI的目标PUSCH,根据新的用于承载第一UCI的目标PUSCH承载的UCI信息,确定相应的UCI传输方式。
具体地,当丢弃目标PUSCH之后,如果还存在与PUCCH时域重叠的其他PUSCH,则可以采用以下任意一种处理方式。
(1)直接丢弃其他所有与PUCCH之间存在时域资源重叠的PUSCH,即不传输这些PUSCH,这些PUSCH上的信息(包括data和UCI)也随之被 丢弃,传输承载第一UCI的PUCCH。
(2)从剩余的与PUCCH之间存在时域资源重叠的PUSCH(即除目标PUSCH以外的其他所有与PUCCH之间存在时域资源重叠的PUSCH)中,进一步确定一个新的用于承载PUCCH中的第一UCI的目标PUSCH,确定这个新的用于承载PUCCH中的第一UCI的目标PUSCH是否承载了第二UCI,如果没有承载第二UCI,则将PUCCH上的第一UCI转移到这个新的目标PUSCH上传输,如果承载了第二UCI,则丢弃这个新的目标PUSCH继续选择下一个新的目标PUSCH,重复此方式,直到找到一个目标PUSCH没有承载第二UCI,将PUCCH上的第一UCI转移到这个目标PUSCH上传输。
可选地,在PUCCH同时承载不同优先级的UCI的情况下,PUCCH的优先级为高优先级或第三优先级;或者,
在PUSCH同时承载不同优先级的UCI的情况下,PUSCH的优先级为高优先级或第三优先级;
其中,第三优先级为高优先级和低优先级以外的其他优先级类型。
具体地,在PUCCH或PUSCH为同时承载不同优先级的UCI的PUCCH或PUSCH的情况下,PUCCH或PUSCH的优先级可以为具有不同优先级的UCI中的高优先级UCI的优先级,即高优先级;或者,PUCCH或PUSCH的优先级也可以为高优先级和低优先级以外的其他优先级类型,即第三优先级,例如,可以为一种混合优先级或比高优先级的优先级更高的一种优先级。
例如,假设PUCCH上同时承载了高优先级的HARQ-ACK和低优先级的HARQ-ACK,则该PUCCH的优先级可以是高优先级;或者可以是第三优先级,如一种混合优先级或比高优先级的优先级更高的一种优先级。PUSCH同理,在此不再赘述。
可选地,多个PUSCH为不能与PUCCH并行传输的PUSCH。
具体地,本公开实施例中,与PUCCH存在时域资源重叠的所有PUSCH为不能与PUCCH并行传输的PUSCH,其具体情形可以包括以下任意一种:
(1)可以是终端不具有并行传输PUCCH和PUSCH的能力;或者,终端具有并行传输PUCCH和PUSCH的能力,但没有配置开启此功能,则任何 一个PUSCH都不能与PUCCH并行传输。
(2)可以是终端具有并行传输PUCCH和PUSCH的能力,也配置开启了此功能,但PUCCH和PUSCH的组合不符合并行传输条件,如PUCCH和PUSCH为相同优先级,则不能并行传输,PUCCH和PUSCH为不同优先级且在同一个成员载波(Component Carrier,CC)或intra-band CC时不能并行传输,只有PUCCH和PUSCH具有不同的优先级且分别在inter-band CC上时可以并行传输。
图2为本公开实施例提供的上行控制信息UCI传输方法的流程示意图之二,该方法可应用于网络设备(例如基站),如图2所示,该方法包括如下步骤:
步骤200、在承载第一UCI的物理上行控制信道PUCCH的时域资源与多个物理上行共享信道PUSCH的时域资源存在重叠,且多个PUSCH中包括承载第二UCI的PUSCH的情况下,从多个PUSCH中优先选择没有承载第二UCI的PUSCH,在所选择的没有承载第二UCI的PUSCH上接收第一UCI;或者,从多个PUSCH中选择用于承载第一UCI的目标PUSCH,并根据目标PUSCH承载的UCI信息,确定相应的UCI接收方式;
其中,PUCCH和承载第二UCI的PUSCH具有不同的优先级,或者第一UCI中包含第一优先级的UCI,第二UCI中包含第二优先级的UCI。
具体地,第一UCI指的是PUCCH上承载的UCI,第一UCI可以是一个或多个UCI,当第一UCI为多个时,第一UCI可以理解为PUCCH上承载的UCI的集合。或者,第一UCI也可以指PUCCH上承载的某一种特定的UCI,例如HARQ-ACK,如果PUCCH上还同时承载了其他UCI,例如SR,第一UCI可以不包含其他UCI,以第一UCI为HARQ-ACK为例,则仅承载HARQ-ACK的PUCCH,与同时承载HARQ-ACK和SR的PUCCH都称之为承载第一UCI的PUCCH。
与PUCCH存在时域资源重叠的多个PUSCH中包括承载第二UCI的PUSCH,第二UCI可以是一个或多个UCI,当第二UCI为多个时,第二UCI可以理解为承载第二UCI的PUSCH上承载的UCI的集合。或者,第二UCI 也可以指PUSCH上承载的某一种特定的UCI,例如CSI,如果PUSCH上还同时承载了其他UCI,例如HARQ-ACK,第二UCI可以不包含其他UCI,以第二UCI为CSI为例,则仅承载CSI的PUSCH,与同时承载HARQ-ACK和CSI的PUSCH都称之为承载第二UCI的PUSCH。
第一UCI中包含第一优先级的UCI,第二UCI中包含第二优先级的UCI,可以理解为第一UCI中包含的某一种UCI与第二UCI中包含的某一种UCI具有不同的优先级。第一优先级和第二优先级表示不同的优先级,如第一优先级为高优先级,第二优先级为低优先级;或者,第一优先级为低优先级,第二优先级为高优先级,在此并不对第一优先级和第二优先级的具体类型做限制,只要第一优先级和第二优先级不同即可。
例如,第一UCI为高优先级的HARQ-ACK,第二UCI为低优先级的HARQ-ACK、低优先级的CSI中的一个或组合;或者,第一UCI为低优先级的HARQ-ACK、低优先级的CSI中的一个或组合,第二UCI为高优先级的HARQ-ACK、高优先级的CSI中的一个或组合;或者,第一UCI为高优先级的HARQ-ACK+低优先级的HARQ-ACK时,第二UCI为高优先级的CSI或低优先级的CSI中的一个或组合都是符合条件的。
可选地,可以是第一UCI至少包含高优先级的UCI,第二UCI至少包含低优先级的UCI;或者,也可以是第一UCI至少包含低优先级的UCI,第二UCI至少包含高优先级的UCI。
第一UCI至少包含高优先级的UCI,第二UCI至少包含低优先级的UCI的情形举例如下:
例如,第一UCI为高优先级的HARQ-ACK,第二UCI为低优先级的CSI(如原本配置在PUCCH上传输的周期CSI、SP-CSI等认为是低优先级CSI,如果CSI本身是在PUSCH上传输的,如PUSCH上传输的A-CSI、SP-CSI,其优先级是可以根据触发A-CSI或SP-CSI的PDCCH中的优先级指示域指示所得到的,可以是高优先级或低优先级);
例如,第一UCI为高优先级的HARQ-ACK,第二UCI包含低优先级的HARQ-ACK和低优先级的CSI;
例如,第一UCI包含高优先级的HARQ-ACK和低优先级的HARQ-ACK,第二UCI为低优先级的CSI。
第一UCI至少包含低优先级的UCI,第二UCI至少包含高优先级的UCI的情形举例如下:
例如,第一UCI为低优先级的HARQ-ACK,第二UCI为高优先级的CSI;
例如,第一UCI为低优先级的HARQ-ACK,第二UCI包含高优先级的HARQ-ACK和高优先级的CSI;
例如,第一UCI包含低优先级的HARQ-ACK和高优先级的HARQ-ACK,第二UCI为高优先级的CSI;
例如,第一UCI包含低优先级的HARQ-ACK和低优先级的CSI,第二UCI为高优先级的CSI;
例如,第一UCI包含低优先级的HARQ-ACK和低优先级的CSI,第二UCI包含高优先级的HARQ-ACK和高优先级的CSI;
例如,第一UCI为低优先级的CSI,第二UCI包括高优先级的HARQ-ACK、高优先级的CSI中的至少一种。
可选地,上述第一UCI和第二UCI满足以下任一条件或组合条件:
第一UCI包含的UCI和第二UCI包含的UCI中存在不支持复用传输的UCI,这可以理解为第一UCI中包含的某一种UCI与第二UCI中包含的某一种UCI不支持复用传输,例如假设不支持具有不同优先级的HARQ-ACK和CSI复用传输,第一UCI中包含高优先级的HARQ-ACK,第二UCI中包含低优先级的CSI,则符合该条件;或者,
第一UCI包括HARQ-ACK和/或CSI中的一种或多种,第二UCI包括HARQ-ACK和/或CSI中的一种或多种。
在承载第一UCI的PUCCH和多个PUSCH存在时域资源重叠,且该多个PUSCH中包括存在承载第二UCI的PUSCH的情况下,本公开实施例提供一种UCI传输的解决方案,其中针对网络设备(例如基站)侧,该解决方案可以包括以下方法一和方法二。
方法一:从该多个PUSCH中优先选择没有承载第二UCI的PUSCH,在 选择出一个没有承载第二UCI的PUSCH后,在所选出的没有承载第二UCI的PUSCH上接收第一UCI,也就是说,接收UCI时,可以接收所选出的没有承载第二UCI的PUSCH,并从中获得第一UCI,不需要接收原本承载该第一UCI的PUCCH。
方法二:从该多个PUSCH中选择一个目标PUSCH,该目标PUSCH可能是用于承载第一UCI的PUSCH,在选择出目标PUSCH后,根据目标PUSCH承载的UCI信息,确定相应的UCI接收方式,也就是说,在选择出目标PUSCH后,可以根据该目标PUSCH上本身承载的UCI,来确定相应的UCI接收方式。
其中,方法二中选择目标PUSCH,可以按照现有技术中的规则进行,或现有技术中的规则与是否支持不同优先级复用传输、优先级等的组合进行(具体结合的顺序可以是任意一种预定义的形式,例如将根据优先级选择PUSCH的规则增加到上述选择步骤中的任何一步的前面或后面都可以),在此不做具体限制。即方法二中选择目标PUSCH并不考虑PUSCH上承载的UCI是否能支持与第一UCI的同时传输。其中,现有技术中的规则可以是根据是否承载A-CSI、PUSCH所在载波的载波编号、PUSCH是否具有对应的PDCCH、PUSCH起始位置的组合规则进行选择,例如优先选择承载A-CSI的PUSCH,在没有承载A-CSI的PUSCH时,如果同时存在具有PDCCH调度的PUSCH(DG PUSCH)和没有PDCCH调度的PUSCH(CG PUSCH,SP-CSI PUSCH等),优先选择DG PUSCH,按照上述规则选择之后,如果多个载波上都有PUSCH,优先选择载波编号低的载波上的PUSCH,如果选择的载波上存在多个时域上不重叠的PUSCH与PUCCH重叠,选择最早的PUSCH。
本公开实施例提供的上行控制信息UCI传输方法,网络设备可以在承载第一UCI的PUCCH和多个PUSCH存在时域资源重叠,且该多个PUSCH中包括存在承载第二UCI的PUSCH的情况下,从该多个PUSCH中优先选择没有承载第二UCI的PUSCH,然后在所选择的没有承载第二UCI的PUSCH上接收第一UCI,避免了不同优先级UCI在同一PUSCH上传输可能导致无法正常传输的问题;或者,根据从该多个PUSCH中选择的目标PUSCH上承载 的UCI信息,来确定相应的接收方式,从而针对相关场景没有明确的传输方案的问题,给出具体的UCI传输方法,保证系统的正常工作。
可选地,在方法一中,优先选择没有承载第二UCI的PUSCH进一步包括以下任意一种:
优先选择没有承载第二UCI的PUSCH,优先选择与PUCCH具有相同优先级的PUSCH两者的组合;或者,

优先选择没有承载第二UCI的PUSCH,优先选择与PUCCH具有相同优先级的PUSCH,优先选择支持不同优先级复用传输的PUSCH三者的组合。
具体地,方法一中,优先选择没有承载第二UCI的PUSCH,可以是在与PUCCH存在时域资源重叠的所有PUSCH中,先按照如下规则1或规则1与规则2、3中的一个或多个的组合进行选择,然后再根据现有技术中的规则进行选择,如根据是否承载A-CSI、PUSCH所在载波的载波编号、PUSCH是否具有对应的PDCCH、PUSCH起始位置的组合进行选择等。
规则1:选择没有承载第二UCI的PUSCH。
规则2:选择具有与PUCCH相同优先级的PUSCH。
规则3:选择支持不同优先级复用的PUSCH,其中优先级可以是指信道的优先级或UCI的优先级等,此处不做具体限制。
其中,进行选择时,采用规则1、规则2、规则3可以具有不同的顺序组合,例如,可以采用规则1+现有技术;规则1+规则2+现有技术;规则1+规则3+现有技术;规则1+规则2+规则3+现有技术;规则2+规则1+现有技术;规则3+规则1+现有技术;规则1+规则3+规则2+现有技术;规则2+规则1+规则3+现有技术;规则3+规则1+规则2+现有技术;规则2+规则3+规则1+现有技术;规则3+规则2+规则1+现有技术,等等。上述组合的书写顺序代表了使用规则的先后顺序。
例如,在与PUCCH存在时域资源重叠的所有PUSCH中,先选择没有承载第二UCI的PUSCH,再根据现有技术方式进行选择;
例如,在与PUCCH存在时域资源重叠的所有PUSCH中,先选择没有承载第二UCI的PUSCH,再选择具有与PUCCH相同优先级的PUSCH,再根据现有技术方式进行选择;
例如,在与PUCCH存在时域资源重叠的所有PUSCH中,先选择具有与PUCCH相同优先级的PUSCH,再选择没有承载第二UCI的PUSCH,再根据现有技术方式进行选择;
例如,在与PUCCH存在时域资源重叠的所有PUSCH中,先选择没有承载第二UCI的PUSCH,再选择支持不同优先级复用的PUSCH,再根据现有技术方式进行选择;
例如,在与PUCCH存在时域资源重叠的所有PUSCH中,先选择支持不同优先级复用的PUSCH,再选择没有承载第二UCI的PUSCH,再根据现有技术方式进行选择;
例如,在与PUCCH存在时域资源重叠的所有PUSCH中,先选择没有承载第二UCI的PUSCH,再选择具有与PUCCH相同优先级的PUSCH,再选择支持不同优先级复用的PUSCH,再根据现有技术方式进行选择;
例如,在与PUCCH存在时域资源重叠的所有PUSCH中,先选择没有承载第二UCI的PUSCH,再选择支持不同优先级复用的PUSCH,再选择具有与PUCCH相同优先级的PUSCH,再根据现有技术方式进行选择;
例如,在与PUCCH存在时域资源重叠的所有PUSCH中,先选择支持不同优先级复用的PUSCH,再选择具有与PUCCH相同优先级的PUSCH,再选择没有承载第二UCI的PUSCH,再根据现有技术方式进行选择;
例如,在与PUCCH存在时域资源重叠的所有PUSCH中,先选择支持不同优先级复用的PUSCH,再选择没有承载第二UCI的PUSCH,再选择具有与PUCCH相同优先级的PUSCH,再根据现有技术方式进行选择;
例如,在与PUCCH存在时域资源重叠的所有PUSCH中,先选择具有与PUCCH相同优先级的PUSCH,再选择支持不同优先级复用的PUSCH,再选择没有承载第二UCI的PUSCH,再根据现有技术方式进行选择;
例如,在与PUCCH存在时域资源重叠的所有PUSCH中,先选择具有与 PUCCH相同优先级的PUSCH,再选择没有承载第二UCI的PUSCH,再选择支持不同优先级复用的PUSCH,再根据现有技术方式进行选择。
通过上述方式选择出一个没有承载第二UCI的PUSCH后,便可以在所选出的没有承载第二UCI的PUSCH上接收第一UCI,从而避免了不同优先级UCI在同一PUSCH上传输可能导致无法正常传输的问题,保证了系统的正常工作。
可选地,在方法二中,根据目标PUSCH承载的UCI信息,确定相应的UCI接收方式,包括:
在目标PUSCH不为承载第二UCI的PUSCH的情况下,在目标PUSCH上接收第一UCI;或者,
在目标PUSCH为承载第二UCI的PUSCH的情况下,根据以下任意一项进行接收:
确定第二UCI被丢弃,在目标PUSCH中接收第一UCI;或者,
确定第二UCI中的部分UCI被丢弃,在目标PUSCH中接收第一UCI和第二UCI中剩余的UCI;或者,
确定第一UCI中的部分UCI被丢弃,在目标PUSCH中接收第一UCI中剩余的UCI和第二UCI;或者,
在目标PUSCH中接收第一UCI和第二UCI;或者,
确定目标PUSCH被丢弃或确定PUCCH被丢弃。
具体地,方法二中,从多个PUSCH中选择出目标PUSCH后,可以根据该目标PUSCH承载的UCI信息,确定相应的UCI接收方式。
具体来说,在该目标PUSCH不是承载第二UCI的PUSCH的情况下,即该目标PUSCH没有承载第二UCI的情况下,则可以在该目标PUSCH上接收第一UCI。
在该目标PUSCH是承载第二UCI的PUSCH的情况下,即该目标PUSCH承载第二UCI的情况下,则可以采用以下任意一种方式进行接收。
方式1:若确定第二UCI被丢弃(例如,根据与终端之间的预定规则,确定终端侧丢弃第二UCI),则在目标PUSCH中接收第一UCI;或者,若确 定第二UCI中的部分UCI(例如不能与第一UCI复用传输的UCI)被丢弃,则在目标PUSCH中接收第一UCI和第二UCI中剩余的UCI;或者,若确定第一UCI中的部分UCI(例如不能与第二UCI复用传输的UCI)被丢弃,则在目标PUSCH中接收第一UCI中剩余的UCI和第二UCI。
方式2:直接在目标PUSCH中接收第一UCI和第二UCI。
方式3:若确定目标PUSCH被丢弃,则不接收目标PUSCH,包括不接收目标PUSCH上的data和UCI;或者,若确定PUCCH被丢弃,则不接收承载第一UCI的PUCCH,第一UCI也随着PUCCH被丢弃,仅接收PUSCH。
可选地,确定目标PUSCH被丢弃之后,该方法还包括:
确定其他所有与PUCCH之间存在时域资源重叠的PUSCH都被丢弃,接收承载第一UCI的PUCCH;或者,
从剩余的与PUCCH之间存在时域资源重叠的PUSCH中,选择新的用于承载第一UCI的目标PUSCH,根据新的用于承载第一UCI的目标PUSCH承载的UCI信息,确定相应的UCI接收方式。
具体地,若确定目标PUSCH被丢弃,如果还存在与PUCCH时域重叠的其他PUSCH,则可以采用以下任意一种处理方式。
(1)进一步确定其他所有与PUCCH之间存在时域资源重叠的PUSCH都被丢弃,则不接收这些PUSCH,包括不接收这些PUSCH上的data和UCI,仅接收承载第一UCI的PUCCH。
(2)从剩余的与PUCCH之间存在时域资源重叠的PUSCH(即除目标PUSCH以外的其他所有与PUCCH之间存在时域资源重叠的PUSCH)中,进一步确定一个新的用于承载PUCCH中的第一UCI的目标PUSCH,确定这个新的用于承载PUCCH中的第一UCI的目标PUSCH是否承载了第二UCI,如果没有承载第二UCI,则在这个新的目标PUSCH上接收第一UCI,如果承载了第二UCI,则确定这个新的目标PUSCH被丢弃,继续选择下一个新的目标PUSCH,重复此方式,直到找到一个目标PUSCH没有承载第二UCI,在这个目标PUSCH上接收第一UCI。
可选地,在PUCCH同时承载不同优先级的UCI的情况下,PUCCH的优 先级为高优先级或第三优先级;或者,
在PUSCH同时承载不同优先级的UCI的情况下,PUSCH的优先级为高优先级或第三优先级;
其中,第三优先级为高优先级和低优先级以外的其他优先级类型。
具体地,在PUCCH或PUSCH为同时承载不同优先级的UCI的PUCCH或PUSCH的情况下,PUCCH或PUSCH的优先级可以为具有不同优先级的UCI中的高优先级UCI的优先级,即高优先级;或者,PUCCH或PUSCH的优先级也可以为高优先级和低优先级以外的其他优先级类型,即第三优先级,例如,可以为一种混合优先级或比高优先级的优先级更高的一种优先级。
例如,假设PUCCH上同时承载了高优先级的HARQ-ACK和低优先级的HARQ-ACK,则该PUCCH的优先级可以是高优先级;或者可以是第三优先级,如一种混合优先级或比高优先级的优先级更高的一种优先级。PUSCH同理,在此不再赘述。
可选地,多个PUSCH为不能与PUCCH并行传输的PUSCH。
具体地,本公开实施例中,与PUCCH存在时域资源重叠的所有PUSCH为不能与PUCCH并行传输的PUSCH,其具体情形可以包括以下任意一种:
(1)可以是终端不具有并行传输PUCCH和PUSCH的能力;或者,终端具有并行传输PUCCH和PUSCH的能力,但没有配置开启此功能,则任何一个PUSCH都不能与PUCCH并行传输。
(2)可以是终端具有并行传输PUCCH和PUSCH的能力,也配置开启了此功能,但PUCCH和PUSCH的组合不符合并行传输条件,如PUCCH和PUSCH为相同优先级,则不能并行传输,PUCCH和PUSCH为不同优先级且在同一个成员载波(Component Carrier,CC)或intra-band CC时不能并行传输,只有PUCCH和PUSCH具有不同的优先级且分别在inter-band CC上时可以并行传输。
本公开各实施例提供的方法是基于同一申请构思的,因此终端侧和网络设备侧方法的实施可以相互参见,重复之处不再赘述。
以下通过具体实施例对本公开各上述实施例提供的方法进行举例说明。
实施例1:图3为本公开实施例提供的PUCCH和PUSCH时域资源重叠示意图,如图3所示,图中LP表示低优先级,HP表示高优先级,AN为HARQ-ACK的缩写,标示HP AN的信道为承载高优先级HARQ-ACK(HP AN)的高优先级(HP)PUCCH,第一UCI即为HP AN,第二UCI为LP CSI(即LP PUSCH1上携带的CSI),图中没有写明承载CSI的PUSCH(LP PUSCH2和LP PUSCH3)即为没有承载CSI的PUSCH。
终端侧:图4为本公开实施例提供的UCI传输方法实施示意图之一,图中标注的解释同图3,如图4所示,先在与PUCCH重叠的PUSCH中选择不包含CSI的PUSCH,即LP PUSCH2和LP PUSCH3;然后在LP PUSCH2和LP PUSCH3中根据现有的PUSCH选择规则,选择出一个PUSCH,例如假设这两个PUSCH都不承载A-CSI且都具有PDCCH,则根据载波编号最小原则,选择LP PUSCH2用于承载PUCCH上的HP AN,即UE侧将PUCCH上的HP AN转移到LP PUSCH2上,发送携带HP AN的LP PUSCH2,并丢弃PUCCH,其他PUSCH可以正常发送,因为不发送PUCCH,则没有PUCCH和PUSCH之间的冲突,多个载波上的PUSCH是可以并行发送的。需要说明的是,如果所有PUSCH都是包含了LP CSI的PUSCH,则按照PUSCH选择规则选择出一个承载LP CSI的PUSCH用于承载PUCCH上的HP AN,此时可以按照实施例2中的方式来进行传输;或者,基站和终端预先约定不期待出现所有与PUCCH重叠的PUSCH中都是包含了LP CSI的PUSCH,即按照优选不包含LP CSI的PUSCH的选择规则,总是可以选择出一个没有LP CSI的PUSCH用于承载PUCCH上的HP AN。
基站侧:采用与终端侧相同的方式确定LP PUSCH2为传输PUCCH上的HP AN的PUSCH,则基站接收携带HP AN的LP PUSCH2,并从中获得HP AN,并在其他载波上接收其他PUSCH,不需要接收PUCCH。
需要说明的,上述实施例1中,将HP AN替换为HP AN+LP AN,即PUCCH中承载了HP AN和LP AN,则PUCCH认为是高优先级信道,上述方式同样适用;上述实施例中交换PUCCH和PUSCH的优先级,即将HP PUCCH替换为LP PUCCH,将LP PUSCH替换为HP PUSCH,相关方法同样适用。
实施例2:图5为本公开实施例提供的PUCCH和选定PUSCH示意图,图中标注的解释同实施例1(本实施例中,图5-图15各图中标注的解释均可参考实施例1),如图5所示,假设承载HP AN的PUCCH与多个PUSCH重叠的情况下,按照PUSCH选择规则选择了一个承载LP CSI的LP PUSCH(例如按照现有技术中的方案,或现有技术的方案与是否支持不同优先级复用传输、优先级等的组合),则可以有多种传输方式。
采用方式1:
终端侧:图6为本公开实施例提供的UCI传输方法实施示意图之二,如图6所示,确定丢弃LP CSI,将PUCCH上的HP AN转移到LP PUSCH上进行发送,从而不发送PUCCH。其中,HP AN在LP PUSCH上按照现有技术中定义的AN在PUSCH上的传输方式进行传输,例如根据AN比特数确定采用puncture方式还是rate matching方式传输,根据对应AN的资源偏移参数(beta-offset)确定PUSCH上承载AN的资源,根据对应AN的资源映射方式确定AN的资源所在位置并进行映射,其中,如果高层信令对LP PUSCH配置了针对不同优先级的AN的资源偏移参数,则使用HP AN对应的资源偏移参数计算AN资源,如果只配置了一种资源偏移参数,则不用区分AN的优先级,直接使用即可;如果还存在其他PUSCH,则其他PUSCH正常发送。
基站侧:采用与终端侧相同的方式确定传输行为,并按照对应行为进行接收;
采用方式2:
终端侧:图7为本公开实施例提供的UCI传输方法实施示意图之三,如图7所示,直接将HP AN转移到LP PUSCH上与LP CSI一起在PUSCH上传输。其中,HP AN和LP CSI在LP PUSCH上按照现有技术中定义的AN和CSI在PUSCH上的传输方式进行传输,例如AN和CSI独立编码,AN和CSI分别按照对应AN和CSI的资源偏移参数确定其在PUSCH上的资源大小,并根据AN和CSI分别的映射规则找到资源位置进行映射,其中,如果高层信令对LP PUSCH配置了针对不同优先级的AN\CSI的资源偏移参数,则使用HP AN对应的资源偏移参数计算AN资源,使用LP CSI对应的资源偏移 参数计算CSI资源,如果对一种UCI只配置了一种资源偏移参数,则不用区分优先级,直接使用该UCI对应的资源偏移参数计算资源即可;如果还存在其他PUSCH,则其他PUSCH正常发送。
基站侧:采用与终端侧相同的方式确定传输行为,并按照对应行为进行接收。
采用方式3:
终端侧:图8为本公开实施例提供的UCI传输方法实施示意图之四,如图8所示,确定丢弃LP PUSCH with LP CSI,只发送承载HP AN的PUCCH,如果其他载波上还存在与PUCCH重叠的PUSCH,则丢弃这些PUSCH或者在剩余的PUSCH中再次选择一个目标PUSCH,确定是否承载了第二UCI,如果没有,则将PUCCH上的UCI转移到目标PUSCH上传输,如果是,丢弃这个目标PUSCH继续选择下一个目标PUSCH,以此类推。当然也可以采用另一种方式,即丢弃PUCCH;对于PUCCH是LP的情况下,推荐丢弃PUCCH。
基站侧:采用与终端侧相同的方式确定传输行为,并按照对应行为进行接收。
需要说明的是,实施例2中:
1)将HP AN替换为LP AN,将LP PUSCH1with LP CSI替换为HP PUSCH1with HP CSI,实施例2所述的方法同样适用,如图9所示,图9为本公开实施例提供的UCI传输方法实施示意图之五,如图9所示,其中采用方式3时图中给出的是丢弃PUCCH的方式。
