Description

物理上行控制信道传输方法及装置、通信设备及存储介质 技术领域
本公开涉及无线通信技术领域但不限于无线通信技术领域,尤其涉及一种物理上行控制信道(Physical Uplink Control Channel,PUCCH)的传输方法及装置、通信设备及存储介质。
背景技术
为了改善小区边缘的覆盖,在服务区内提供更为均衡的服务质量,多点协作在新无线(New Radio,NR)系统中仍然是一种重要的技术手段。
从网络形态角度考虑,以大量的分布式接入点和基带集中处理的方式进行网络部署将更加有利于提供均衡的用户体验速率,并且显著的降低越区切换带来的时延和信令开销。
随着频段的升高,从保证网络覆盖的角度出发,也需要相对密集的接入点部署。而在高频段,随着有源天线设备集成度的提高,将更加倾向于采用模块化的有源天线阵列。每个收发点(Transmission Reception Point,TRP)的天线阵可以被分为若干相对独立的天线面板,因此整个阵面的形态和端口数都可以随部署场景与业务需求进行灵活的调整。
而天线面板或TRP之间也可以由光纤连接,进行更为灵活的分布式部署。在毫米波波段,随着波长的减小,人体或车辆等障碍物所产生的阻挡效应将更为显著。
因此,从保障链路连接鲁棒性的角度出发,也可以利用多个TRP或天线面板之间的协作,从面向多个TRP或天线面板角度的多个波束进行传输/接收,从而降低阻挡效应带来的不利影响。
发明内容
本公开实施例提供一种PUCCH的传输方法及装置、通信设备及存储介质。

本公开实施例第二方面提供一种PUCCH的传输方法,由基站执行,所述方法包括:
接收一个终端的多个天线面板基于频分复用FDM进行PUCCH的非相干联合传输NC-JT;不同的所述天线面板对应不同的传输配置指示TCI。
本公开实施例第三方面提供一种PUCCH的传输装置,应用于终端,所述装置包括:
第一传输单元,被配置为根据传输配置指示TCI,通过所述终端的多个天线面板基于频分复用 FDM进行PUCCH的非相干联合传输NC-JT;其中,不同的所述天线面板对应不同的所述TCI。

第二传输单元,被配置为接收一个终端的多个天线面板基于频分复用FDM进行PUCCH的非相干联合传输NC-JT;不同的所述天线面板对应不同的传输配置指示TCI。
本公开实施例第五方面提供一种通信设备,包括处理器、存储器及存储在存储器上并能够有所述处理器运行的可执行程序,其中,所述处理器运行所述可执行程序时执行如前述第一方面提供的PUCCH的传输方法。
本公开实施例第六方面提供一种计算机存储介质,所述计算机存储介质存储有可执行程序;所述可执行程序被处理器执行后,能够实现前述的第一方面提供的PUCCH的传输方法。
本公开实施例提供的技术方案,根据不同的天线面板对应不同的TCI,终端的多个天线面板基于FDM进行PUCCH的非相干联合传输NC-JT。如此,终端可以基于不同的TCI实现多个天线面板同时进行上行传输,提升通信系统的吞吐量,从而提升上行数据传输效率。另外基于多个天线面板进行的NC-JT,可以降低对多点协作传输的传输点同步需求,从而提升传输可靠性。

请参考图1,其示出了本公开实施例提供的一种无线通信系统的结构示意图。如图1所示,无线通信系统是基于蜂窝移动通信技术的通信系统,该无线通信系统可以包括:若干个终端11以及若干个接入设备12。
其中,终端11可以是指向用户提供语音和/或数据连通性的设备。终端11可以经无线接入网(Radio Access Network,RAN)与一个或多个核心网进行通信,终端11可以是物联网终端,如传感器设备、移动电话(或称为“蜂窝”电话)和具有物联网终端的计算机,例如,可以是固定式、便携式、袖珍式、手持式、计算机内置的或者车载的装置。例如,站(Station,STA)、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、远程终端(remote terminal)、接入终端(access terminal)、用户装置(user terminal)、用户代理(user agent)、用户设备(user device)、或用户终端(user equipment,终端)。或者,终端11也可以是无人飞行器的设备。或者,终端11也可以是车载设备,比如,可以是具有无线通信功能的行车电脑,或者是外接行车电脑的无线通信设备。或者,终端11也可以是路边设备,比如,可以是具有无线通信功能的路灯、信号灯或者其它路边设备等。
接入设备12可以是无线通信系统中的网络侧设备。其中,该无线通信系统可以是第四代移动通信技术(the 4th generation mobile communication,4G)系统,又称长期演进(Long Term Evolution,LTE)系统;或者,该无线通信系统也可以是5G系统,又称新空口(new radio,NR)系统或5G NR系统。或者,该无线通信系统也可以是5G系统的再下一代系统。其中,5G系统中的接入网可以称为NG-RAN(New Generation-Radio Access Network,新一代无线接入网)。或者,MTC系统。
其中,接入设备12可以是4G系统中采用的演进型接入设备(eNB)。或者,接入设备12也可 以是5G系统中采用集中分布式架构的接入设备(gNB)。当接入设备12采用集中分布式架构时,通常包括集中单元(central unit,CU)和至少两个分布单元(distributed unit,DU)。集中单元中设置有分组数据汇聚协议(Packet Data Convergence Protocol,PDCP)层、无线链路层控制协议(Radio Link Control,RLC)层、媒体访问控制(Media Access Control,MAC)层的协议栈;分布单元中设置有物理(Physical,PHY)层协议栈,本公开实施例对接入设备12的具体实现方式不加以限定。
接入设备12和终端11之间可以通过无线空口建立无线连接。在不同的实施方式中,该无线空口是基于第四代移动通信网络技术(4G)标准的无线空口;或者,该无线空口是基于第五代移动通信网络技术(5G)标准的无线空口,比如该无线空口是新空口;或者,该无线空口也可以是基于5G的更下一代移动通信网络技术标准的无线空口。
可选的,上述无线通信系统还可以包含网络管理设备13。若干个接入设备12分别与网络管理设备13相连。其中,网络管理设备13可以是无线通信系统中的核心网设备,比如,该网络管理设备13可以是演进的数据分组核心网(Evolved Packet Core,EPC)中的移动性管理实体(Mobility Management Entity,MME)。或者,该网络管理设备也可以是其它的核心网设备,比如服务网关(Serving GateWay,SGW)、公用数据网网关(Public Data Network GateWay,PGW)、策略与计费规则功能单元(Policy and Charging Rules Function,PCRF)或者归属签约用户服务器(Home Subscriber Server,HSS)等。对于网络管理设备13的实现形态,本公开实施例不做限定。
如图2所示,本公开实施例提供一种PUCCH的传输方法,由终端执行,所述方法包括:
S110:根据TCI,所述终端的多个天线面板基于FDM进行PUCCH的NC-JT;其中,不同的所述天线面板对应不同的所述TCI。
在本公开实施例中,一个终端可以包括多个用于收发数据的天线面板,每个天线面板上可包括至少一个天线振子。其中,每个天线面板可以分别对应一个收发点TRP,每一天线面板可用于向对应的TRP进行PUCCH的NC-JT传输。
在一个实施例中,TCI可以关联终端的解调参考信号(Demodulation of Reference Signal,DMRS)端口,例如,不同TCI关联的DMRS端口或DMRS端口组合相同。其中,一个DMRS端口组合可以包含至少一个DMRS端口,例如,一个DMRS端口组合中的多个DMRS端口可以是准共址(Quasi-CoLocation,QCL)的。
这里,非相干联合传输NC-JT,表征每个上行数据只映射到QCL的TRP或天线面板所对应的端口上,不同的上行数据可以被映射到QCL的不同端口上,无需将所有的传输点统一视为一个虚拟阵列。
多个端口QCL,表示多个端口对应的指定大尺度参数相同,其中,指定的大尺度参数可以包括多普勒频移、多普勒扩展、平均时延以及时延扩展中的至少一个。即只要多个端口的指定大尺度参数一致,不论该多个端口的实际物理位置或对应的天线面板朝向是否存在差异,均可认为该多个端口属于相同的位置,即准共址QCL。
示例性的,在每个码分复用(Code Division Multiplexing,CDM)组内的DMRS端口是QCL的。
在一个实施例中,如图3A、3B和3C所示,图3A为单点传输的传输方式示意图、图3B为相干联合传输(Coherent-Joint Transmission,C-JT)的传输方式示意图,图3C为NC-JT的传输方式示意图。其中,收发点1和收发点2为与天线面板对应的收发点TRP。
单点传输中,终端向同一个收发点接收所有码字对应的数据传输层(Layer)1-4。C-JT传输中,终端向两个收发点接收两个收发点联合预编码后的所有码字对应的数据传输层1-4。NC-JT传输中,终端从不同的收发点分别接收码字对应的数据传输层1-4,例如终端从收发点1接收码字0对应的两层数据传输层1-2,以及从收发点2接收码字1对应的两层数据传输层3-4。
示例性的,如图4所示,一个终端包含两个天线面板,两个天线面板的朝向可以相反。两个天线面板可分别用于向基站的收发点收发点1和收发点2同时发送上行数据,例如上行数据可以为上行控制信息(Uplink Control Information,UCI)等。
在一个实施例中,终端向TRP进行的所述NC-JT可以为:免调度的NC-JT,或者,下行控制信息(Downlink Control Information,DCI)DCI调度的NC-JT。
在一个实施例中,为了支持不同UCI比特数范围的传输,从承载UCI的比特数角度,PUCCH传输可分为两类:一类为用于承载1到2比特UCI传输的PUCCH格式,另一类为用于承载大于2比特UCI传输的PUCCH格式。
在另一个实施例中,从上行覆盖和传输时延角度,PUCCH传输也可以分为两类:一类为短PUCCH格式的PUCCH传输,占用1或2个符号传输,另一类为长PUCCH格式的PUCCH传输,占用4到14个符号传输。
具体地,PUCCH格式可如表1所示:
Figure PCTCN2022090654-appb-000001
表1
其中,OCC为正交掩码(Orthogonal cover code,OCC)。表1中所有的PUCCH格式均支持时隙内跳频,而只有PUCCH格式1、3和4支持时隙间跳频。
对于PUCCH格式1、3和4的PUCCH传输,可以通过无线资源控制(Radio Resource Control, RRC)信令配置时隙级别的重复次数,在相同的时频资源上在连续的多个时隙中进行重复发送,支持的重复次数为1、2、4和8。对于PUCCH格式0和2则不支持时隙间的重复发送。
在一个实施例中,天线面板对应的TCI用于指示天线面板发射波束的波束方向。当不同的天线面板对应不同的TCI,则每一天线面板具备独立的TCI状态(TCI state),因而每一天线面板具备独立的波束发射方向,多个天线面板之间可以实现波束方向不重叠,从而多个天线面板之间相互独立互不干扰。如此,终端的多个天线面板可以用于向基站的多个TRP发送上行数据。
在一个实施例中,TCI可以由基站下发的一个或多个网络信令指示,例如通过下行控制信息(downlink control information,DCI)指示给终端。或者,TCI也可以由统一TCI框架(unified TCI framework)配置或指示。示例性的,统一TCI框架可以将多个天线面板对应的多个联合TCI(joint TCI)或者多个独立TCI(separate TCI)指示给终端。
在一个实施例中,若多天线面板或多收发点(Multiple Panel/Multiple TRP,MP/MTRP)的波束一致性成立,则统一TCI框架可以将多个不同的联合TCI指示给终端的多个天线面板的TCI。
若MP/MTRP的发送波束和接收波束一致性不成立,则统一TCI框架可以将多个独立TCI共同指示给终端的多个天线面板的TCI。
示例性的,假设终端仅有2个天线面板,则终端将被配置2个TCI,这里简化为TCI1和TCI2。例如,天线面板1对应于TCI1,且天线面板2对应于TCI2。
在一个实施例中,TCI也可以由网络协议预先约定,或者,TCI也可以根据空间关系信息(Spatial Relation Info,SRI)确定。
在一个实施例中,一个TCI可以关联PUCCH的NC-JT传输的一个上行控制信息UCI。不同的TCI可以关联相同或者不同的UCI。
示例性的,当不同TCI用于相同UCI的传输时,终端的多个天线面板可以同时实现对一个UCI的传输,从而提升UCI的传输增益和可靠性。当不同TCI用于不同UCI的传输时,终端的多个天线面板可以同时独立传输,实现多个UCI的传输,从而提升UCI传输效率。
在一个实施例中,根据TCI,终端的多个天线面板基于频分复用FDM进行PUCCH的NC-JT,可以包括:终端的多个天线面板根据对应的TCI确定每一天线面板对应的频域资源;基于多个天线面板对应的多个频域资源间的FDM进行PUCCH的NC-JT。
其中,每一天线面板对应的频域资源,可以根据PUCCH资源指示域(PUCCH Resource Indicator,PRI)指示的PUCCH资源对应的频域资源确定。例如,当PRI指示一个PUCCH资源时,不同天线面板对应的频域资源为该PUCCH资源的频域资源中的不同部分。当PRI指示多个PUCCH资源时,不同天线面板对应的频域资源为不同PUCCH资源对应的频域资源。
如此,通过为不同天线面板配置不同的TCI以及采用频分复用FDM,终端可以实现多个天线面板同时进行上行传输,且多个天线面板之间相互干扰较小,提升通信系统的吞吐量,从而提升上行数据传输效率。此外,通过多个天线面板进行的NC-JT,可以降低对多点协作传输的传输点同步需求,从而提升传输可靠性。
在一些实施例中,不同的所述天线面板面向基站的不同收发点TRP。
这里,基站的不同收发点TRP,可以包括同一基站的多个不同TRP,也可以包括多个基站的不同TRP。
在一些实施例中,不同所述TCI关联的时域资源相同且关联的频域资源不重叠。
在本公开实施例中,不同TCI关联的时域资源相同,则不同TCI对应的不同天线面板在传输UCI时,可以实现同时传输,且由于不同天线面板指向的TRP方向不同,发射的波束方向也不同,因而即便不同TCI关联的时域资源相同也可以产生较小的干扰。
不同TCI关联的频域资源不重叠,则不同TCI对应的不同天线面板在传输UCI时占用不同的频域资源,例如频带,从而通过频分复用FDM降低不同天线面板同时上行传输产生的干扰。
在一些实施例中,不同所述TCI关联的解调参考信号DMRS端口相同。
在一个实施例中,不同TCI关联的DMRS端口组合相同,其中,DMRS端口组合包含一个DMRS端口,或者包含多个QCL的DMRS端口。
在一些实施例中,不同所述TCI关联的预编码矩阵独立。
这里,不同TCI关联的预编码矩阵(precoder)不同。TCI关联的预编码矩阵,可以为终端内预先设定好的预编码矩阵,也可以为基站通过下发网络信令指示的预编码矩阵。其中,不同TCI对应的不同天线面板基于各自对应的预编码矩阵进行PUCCH的NC-JT上行传输。
在一些实施例中,所述终端的多个所述天线面板基于一个PUCCH资源内的FDM进行所述PUCCH的所述NC-JT。
在本公开实施例中,PRI可以指示一个PUCCH资源给终端,用于终端的多个天线面板基于FDM进行PUCCH的NC-JT。此时,多个天线面板的同时上行传输,是基于同一个PUCCH资源进行的NC-JT。
因此,多个天线面板对应的TCI的时域资源相同,且TCI的时域资源为所述一个PUCCH资源对应的时域资源。而基于一个PUCCH资源内的FDM,则不同天线面板对应的TCI所使用的时域资源,分别为所述一个PUCCH资源对应的频域资源的一部分。
在一个实施例中,不同天线面板对应的TCI所使用的频域资源不重叠,且所述一个PUCCH资源对应的频域资源分配给不同TCI,为多个TCI对应的天线面板提供不重叠的频域资源。
在一个实施例中,所述一个PUCCH资源对应的频域资源按照预先设定的分配规则分配给不同TCI,例如,分配规则可以由PRI配置指示,或者可以在终端中预先存储,或者也可以由基站通过下发RRC信令指示等。
示例性的,当终端仅包含2个天线面板时,天线面板1和天线面板2可以分别对应PUCCH资源对应的频域资源的1/2或者1/3等,且天线面板1和天线面板2对应的频域资源不重叠。
在一个实施例中,不同TCI对应的天线面板通过各自不同的频域资源上行传输相同的UCI。如此,基于同一PUCCH资源对应的频域资源分配给多个TCI对应的天线面板,可以在占用较少的PUCCH资源的基础上,完成多传输点协同传输,提升UCI上行传输的传输速率。
如图5所示,本公开实施例提供一种PUCCH的传输方法,由终端执行,所述方法包括:
S210:根据预定义的分配图样,确定不同所述天线面板进行所述PUCCH的NC-JT对应的频域资源;
S220:根据TCI,所述终端的多个天线面板基于FDM进行PUCCH的NC-JT;其中,不同的所述天线面板对应不同的所述TCI。
在本公开实施例中,预定义的分配图样(pattern),可以用于指示对不同天线面板分配的频域资源的信息。分配图样可以由基站通过网络信令等下发至终端,也可以预先存储于终端中。
在一个实施例中,预定义的分配图样,可以为预定义的物理资源块(Physical Resource Block,PRB)的分配图样,用于确定不同所述天线面板进行所述PUCCH的NC-JT对应的PRB的分布情况。例如,分配图样可以指示PRB平均分布,或者PRB间隔分布等。
这里,PRB平均分布表示多个天线面板对应的PRB数量相同或不同,且每一天线面板对应的多个PRB位置连续。
以天线面板数量为2个为例,PRB平均分布时,天线面板1对应的PRB可以为PRB1,PRB2,PRB3和PRB4…等,天线面板2对应的PRB可以为PRB5,PRB6,PRB7和PRB8…等。
PRB间隔分布表示多个天线面板对应的PRB数量相同或不同,且每一天线面板对应的多个PRB与其他天线面板对应的多个PRB位置交叉。例如,对于2个天线面板,2个天线面板分别对应奇数的PRB和偶数的PRB。
以天线面板数量为2个为例,PRB间隔分布时,天线面板1对应的PRB可以为PRB1,PRB3,PRB5和PRB7…等,天线面板2对应的PRB可以为PRB2,PRB4,PRB6和PRB8…等。
在一些实施例中,所述终端的任意一个天线面板对应的物理资源块PRB在频域连续分布;
或者,
所述终端的多个天线面板对应的PRB在频域间隔分布。
如图6所示,本公开实施例提供一种PUCCH的传输方法,由终端执行,所述方法包括:
S310:接收无线资源控制(Radio Resource Control,RRC)信令,其中,所述RRC信令携带至少一个天线面板对应的频域资源的起始PRB;
S320:根据所述RRC信令,确定所述终端的多个天线面板使用的频域资源,其中,所述终端的任意一个天线面板使用的PRB在频域连续分布;
S330:根据TCI,所述终端的多个天线面板基于FDM进行PUCCH的NC-JT;其中,不同的所述天线面板对应不同的所述TCI。
在本公开实施例中,对于同一PUCCH资源内进行FDM的多个天线面板,不同的天线面板对应于PUCCH资源对应的频域资源中不同的PRB。因此可以通过RRC信令指示不同天线面板关联的频域资源中至少一个PRB的起始PRB。
RRC信令可以由基站下发至终端,RRC信令可以携带指示不同TCI对应的天线面板对应的不同频域资源的分配的信息,例如不同天线面板对应的PRB分配的信息。其中,不同天线面板对应的 PRB分配的信息,可包括不同天线面板对应的起始PRB,还可以包括不同天线面板对应的所有PRB。
在一个实施例中,以终端中仅包含2个天线面板为例,天线面板1和天线面板2的起始PRB均可以由RRC信令携带指示。
在一个实施例中,以终端中仅包含2个天线面板为例,天线面板1的起始PRB可根据PRI指示确定,天线面板2的起始PRB可由RRC信令指示。
本公开实施例提供一种PUCCH的传输方法,由终端执行,所述方法包括:
接收跳频传输指示信息,其中,所述跳频传输指示信息包括:跳频指示比特,用于指示所述终端去使能跳频传输;跳频起始PRB指示,用于供所述终端确定至少一个所述天线面板使用的频域资源的起始PRB,其中,所述终端的任意一个天线面板使用的PRB在频域连续分布;
根据所述跳频传输指示信息,确定多个天线面板基于FDM进行PUCCH的NC-JT的频域资源;
根据TCI,所述终端的多个天线面板基于FDM进行PUCCH的NC-JT;其中,不同的所述天线面板对应不同的所述TCI。
在本公开实施例中,对于同一PUCCH资源内进行FDM的多个天线面板,不同的天线面板对应于PUCCH资源对应的频域资源中不同的PRB。因此可以通过跳频传输指示信息指示不同天线面板关联的频域资源中至少一个PRB的起始PRB。
跳频传输指示信息,可以由PRI指示给终端,也可以由基站通过网络信令发送给终端。
在一个实施例中,以终端中仅包含2个天线面板为例,PUCCH资源对应的频域资源分配给天线面板1和天线面板2。跳频传输指示信息可以指示:根据时隙内跳频(intra-slot Frequency Hopping)的至少一个跳频点对应的PRB确定至少一个天线面板使用的频域资源的起始PRB。其中,时隙内跳频的一个时隙可包含多个跳频点,不同的跳频点对应不同的频段。
在一个实施例中,以终端中仅包含2个天线面板为例,天线面板1的起始PRB可根据PRI指示确定,天线面板2可由跳频起始PRB指示确定为时隙内跳频的第二个跳频点对应的PRB(second Hop PRB)。
由于PUCCH的时隙内跳频对应的至少一个跳频点PRB作为至少一个天线面板的起始PRB,因此通过去使能时隙内跳频,减少上行传输过程中出现时隙内跳频导致天线面板的起始PRB被跳频传输占用,从而可以提升天线面板的PUCCH传输可靠性。
如此,通过跳频传输指示信息携带对天线面板使用的频域资源的起始PRB的指示,可以无需构建新的网络信令或者指示信息,从而借用跳频传输指示信息的下发,高效完成对天线面板使用的频域资源的起始PRB的指示,提高信息传输和资源指示的效率。
如图7所示,本公开实施例提供一种PUCCH的传输方法,由终端执行,所述方法包括:
S410:接收多个所述天线面板使用的频域资源参数分配的更新信息;
S420:根据所述更新信息,确定所述终端的多个天线面板使用的频域资源;
S430:根据TCI,所述终端的多个天线面板基于FDM进行PUCCH的NC-JT;其中,不同的所述天线面板对应不同的所述TCI。
这里,更新信息用于指示不同天线面板对应的频域资源参数分配,例如,更新信息可以由PRI指示下发,也可以由基站通过网络信令携带发送至终端。
在一些实施例中,所述接收多个所述天线面板使用的频域资源的更新信息,包括:
接收包含所述更新信息的媒体访问控制控制单元MAC-CE。
在本公开实施例中,MAC-CE可以由PRI指示下发,也可以由基站通过网络信令携带发送至终端的消息。其中,MAC-CE可携带指示多个所述天线面板使用的频域资源参数分配的配置标识符等。
在一些实施例中,所述PUCCH传输的格式为:格式2或者格式3。
这里,由于多个天线面板基于同一PUCCH资源内的FDM进行所述PUCCH的NC-JT,因而PUCCH格式需要支持多个PRB,即结合前述表1中的多种PUCCH格式,可确定多个天线面板基于同一PUCCH资源内的FDM进行所述PUCCH的NC-JT时,支持的PUCCH格式为格式2或格式3。
在一些实施例中,所述PUCCH传输的类型可包括:
不支持重复传输的PUCCH传输。
这里,由于在发生重复传输时,PUCCH传输产生时隙间跳频或时隙内跳频,才能实现在不同时隙或者同一时隙内不同时刻进行多次传输。因此,不支持重复传输的PUCCH传输,可以为不支持时隙间跳频和/或时隙内跳频的PUCCH传输。
在一些实施例中,所述PUCCH传输的类型可包括:
基于时隙内跳频的PUCCH重复传输;
基于时隙间跳频的PUCCH重复传输。
在一个实施例中,由于基于时隙内跳频的PUCCH重复传输需要占用多个跳频点对应的PRB进行重复传输(repetition),因而跳频点PRB不支持用于作为天线面板的起始PRB。
因此,当PUCCH传输的类型为基于时隙内跳频的PUCCH重复传输时,则可以基于RRC信令、更新信息或者MAC-CE确定至少一个天线面板所使用的频域资源对应的起始PRB,而不基于跳频传输指示信息确定至少一个天线面板所使用的频域资源对应的起始PRB。
如图8所示,本公开实施例提供一种PUCCH的传输方法,由终端执行,所述方法包括:
S510:所述终端的多个所述天线面板基于不同PUCCH资源间的FDM进行所述PUCCH的所述NC-JT;其中,不同所述PUCCH资源的时域位置相同且频域位置不同。
在本公开实施例中,不同的所述天线面板对应不同的所述TCI。PRI可以指示多个PUCCH资源给终端,用于终端的多个天线面板基于FDM进行PUCCH的NC-JT,其中,不同天线面板可以对应不同的PUCCH资源,或者,部分天线面板可以对应相同的PUCCH资源,且与剩余天线面板对应的PUCCH资源不同。此时,多个天线面板的同时上行传输,是基于多个不同的PUCCH资源进行的NC-JT。
在一个实施例中,不同天线面板对应不同的PUCCH资源,一个天线面板所使用的时域资源和频域资源均为该天线面板对应的一个PUCCH资源的时域资源和频域资源。多个PUCCH资源的时域资源相同,例如多个PUCCH资源在一个时隙中占用相同的符号,从而实现多天线面板的同时上行 传输,且多个PUCCH资源的频域资源不重叠,从而实现不同天线面板所使用的频域资源不重叠,降低多个天线面板的上行传输对彼此产生的干扰。
在一个实施例中,多个PUCCH资源对应的时域资源和频域资源,可以通过PRI指示。
在另一个实施例中,每一天线面板所使用的时域资源和频域资源,在对应的PUCCH资源的时域资源和频域资源中的占用配置,可以通过PRI指示。
在一个实施例中,每一天线面板对应的PUCCH资源可以由PRI指示,或者可以在终端中预先存储,或者也可以由基站通过下发RRC信令指示等。
示例性的,当终端仅包含2个天线面板时,天线面板1和天线面板2可以分别对应PUCCH资源1和PUCCH资源2,且天线面板1和天线面板2对应的频域资源不重叠。
在一个实施例中,不同TCI对应的天线面板通过对应的不同PUCCH资源的频域资源上行传输相同的UCI。如此,基于不同PUCCH资源对应的频域资源分配给多个TCI对应的天线面板,每一天线面板可使用的频域资源更加充裕,从而每个天线面板-TRP传输方向上的传输码率更高,数据上行传输的稳定性和可靠性更好。
在一些实施例中,所述终端的多个所述天线面板基于在相同PUCCH资源组内的不同PUCCH资源间的FDM进行所述PUCCH的所述NC-JT;
或者,
所述终端的多个所述天线面板基于在不同PUCCH资源组内的不同PUCCH资源间的FDM进行所述PUCCH的所述NC-JT;
其中,一个PUCCH资源组内的任意两个所述PUCCH资源的时域位置相同且频域位置不同。
在本公开实施例中,PRI可以用于指示一个或多个PUCCH资源组,每个PUCCH资源组中可包含至少两个PUCCH资源。
在一个实施例中,PRI还可以指示每一天线面板对应的PUCCH资源组以及该PUCCH资源组中的PUCCH资源。
在一些实施例中,所述PUCCH传输支持的PUCCH格式包括:
PUCCH格式0;
PUCCH格式1;
PUCCH格式2;
PUCCH格式3;
PUCCH格式4。
这里,在不同天线面板分别对应于不同的PUCCH资源时,每一天线面板基于独立的PUCCH资源进行PUCCH资源的NC-JT传输。因此,每一天线面板对应的PUCCH传输无需支持多个PRB,对于前述表1中的多种PUCCH格式均可支持。
在一些实施例中,所述PUCCH传输的类型包括:
基于时隙内跳频的PUCCH重复传输;
基于时隙间跳频的PUCCH重复传输;其中,任意两个所述PUCCH资源的重复传输时域配置参数相同。
在本公开实施例中,由于不同天线面板对应于不同的PUCCH资源,且不同天线面板的时域资源相同,以实现不同天线面板向不同TRP的同时传输。因此,任意两个所述PUCCH资源的重复传输时域配置参数相同,例如重复传输时域配置参数可以包括以下至少之一:重复传输起始时刻、重复传输周期以及重复传输次数。
在一些实施例中,根据传输配置指示TCI,所述终端的多个天线面板基于频分复用FDM进行PUCCH的非相干联合传输NC-JT,包括:
所述终端的不同天线面板根据对应的TCI以及目标码率,基于频分复用FDM进行PUCCH的非相干联合传输NC-JT。
在本公开实施例中,目标码率可以为PRI下发指示的天线面板的传输码率,其中,目标码率可以由PRI指示,也可以由基站通过RRC信令下发指示等。
不同的目标码率可以指示终端的不同天线面板进行PUCCH的NC-JT时的数据传输速率,例如可指示不同的天线面板单位时间发送的比特数等。
该目标码率可由终端的多个天线面板的PUCCH传输使用的调制与编码策略(MCS)来确定,或者,由基站发送的网络信令或者协议约定。
在一个实施例中,目标码率可以为支持一个PUCCH资源内的FDM或多个PUCCH资源间的FDM的码率。
在一些实施例中,所述PUCCH传输包括:单个下行控制信息S-DCI调度的PUCCH传输。
这里,单个下行控制信息(Single-Downlink Control Information,S-DCI)可以为基站下行传输至终端的信息。例如,S-DCI可以为基站通过物理下行控制信道(physical downlink control channel,PDCCH)或者物理下行共享信道(physical downlink shared channel,PDSCH)等下行传输的。
在一个实施例中,S-DCI可以指示PUCCH传输的传输参数及配置信息等。示例性的,对于PUCCH的NC-JT传输,S-DCI可以指示传输的时域资源配置参数,例如基于时隙间跳频的重复传输对应的重复传输周期等时域资源配置参数。
在一些实施例中,所述TCI包括以下之一:
联合TCI;
独立TCI;
空间关系信息。
在本公开实施例中,在统一TCI框架配置下,TCI可包括:联合TCI和独立TCI。
联合TCI可以用于确定出上行波束和下行波束的方向。上行波束用于上行发送,下行波束用于下行接收。
独立TCI可以用于上行波束或者下行波束的方向。上行波束的波束方向,独立TCI可由UL TCI进行指示。
空间关系信息可以包括空间关系信息SRI组合,例如SRI组合可以指示spatialRelationInfo1/2。
在一个实施例中,若没有通过联合TCI或者独立TCI指示终端不同天线面板的上行波束方向,则可以采用空间关系信息指示终端不同天线面板的上行波束方向。
在一些实施例中,所述TCI的指示信息具有多个TCI域;
其中,一个所述TCI域,指示所述终端一个天线面板对应的所述TCI。
这里,一个TCI域可包含一个或多个比特,用于指示终端的一个天线面板的TCI。不同的TCI域指示的天线面板的TCI不同。
在一些实施例中,所述TCI的指示信息具有一个TCI域;
所述TCI域的不同码点,指示所述终端不同天线面板对应的所述TCI。
在本公开实施例中,TCI的指示信息包括了一个统一的TCI域,该TCI域包括一个或多个比特,这些比特的不同比特值为不同码点。一个TCI域的不同码点,可以指示终端的多个天线面板的TCI。
在一个实施例中,TCI域可以划分多个子域,一个子域指示一个天线面板的TCI。一个子域可包括一个或多个比特。
在另一个实施例中,TCI域的一个码点同时对应了多个TCI的组合。
在一些实施例中,所述TCI由以下至少一种信令方式携带:
下行控制信息DCI;
媒体访问控制控制单元(Medium Access Control-Control Element,MAC-CE);
无线资源控制RRC信令。
在一个实施例中,对于配置了时隙内跳频的PUCCH传输,在每一个跳频点上均可基于前述一个或多个实施例公开的传输方法进行PUCCH传输。
在一个实施例中,对于配置了时隙间跳频的PUCCH传输,在每一个时隙级别的跳频点上,均可基于前述一个或多个实施例公开的传输方法进行PUCCH传输。
如图9所示,本公开实施例提供一种PUCCH的传输方法,由基站执行,可包括:
S210:接收一个终端的多个天线面板基于FDM进行PUCCH的NC-JT;不同的所述天线面板对应不同的TCI。
在本公开实施例中,基站可通过多个TRP接收一个终端的多个天线面板基于频分复用FDM进行PUCCH的非相干联合传输NC-JT,其中,不同TRP可以对应不同的天线面板,每一TRP用于接收对应的天线面板进行的PUCCH的NC-JT。
在一个实施例中,基站接收的所述NC-JT可以为:免调度的NC-JT,或者,下行控制信息(Downlink Control Information,DCI)DCI调度的NC-JT。例如,基站下发DCI给终端用于指示NC-JT的调度。
在一个实施例中,基站可以向终端发送DCI指示终端不同天线面板对应的TCI,或者,基站也可以通过指示同一TCI框架配置终端不同天线面板对应的TCI。
在一个实施例中,若多天线面板或多收发点(Multiple Panel/Multiple TRP,MP/MTRP)的波束一致性成立,则基站可以指示统一TCI框架将多个不同的联合TCI指示给终端的多个天线面板的TCI。
若MP/MTRP的发送波束和接收波束一致性不成立,则基站可以指示统一TCI框架将多个独立TCI共同指示给终端的多个天线面板的TCI。
在一个实施例中,TCI也可以由网络协议预先约定,或者,TCI也可以根据基站指示的空间关系信息(Spatial Relation Info,SRI)确定。
在一个实施例中,每一天线面板对应的频域资源,可以由基站通过PUCCH资源指示域(PUCCH Resource Indicator,PRI)指示的PUCCH资源对应的频域资源确定。例如,当基站通过PRI指示一个PUCCH资源时,不同天线面板对应的频域资源为该PUCCH资源的频域资源中的不同部分。当基站通过PRI指示多个PUCCH资源时,不同天线面板对应的频域资源为不同PUCCH资源对应的频域资源。
在一些实施例中,不同的所述天线面板面向所述基站的不同收发点TRP。
这里,基站的不同收发点TRP,可以包括同一基站的多个不同TRP,也可以包括多个基站的不同TRP。
在一些实施例中,不同所述TCI关联的时域资源相同且关联的频域资源不重叠。
在一些实施例中,不同所述TCI关联的解调参考信号DMRS端口相同。
在一些实施例中,不同所述TCI关联的预编码矩阵独立。
在一些实施例中,所述接收一个终端的多个天线面板基于频分复用FDM进行PUCCH的非相干联合传输NC-JT,包括:
接收一个终端的多个天线面板基于一个PUCCH资源内的FDM进行所述PUCCH的所述NC-JT。
在本公开实施例中,基站可以通过PRI指示一个PUCCH资源给终端,用于供终端的多个天线面板基于FDM进行PUCCH的NC-JT。此时,基站的多个TRP接收到的多个天线面板的同时上行传输,是基于同一个PUCCH资源进行的NC-JT。
因此,多个天线面板对应的TCI的时域资源相同,且TCI的时域资源为所述一个PUCCH资源对应的时域资源。而基于一个PUCCH资源内的FDM,则不同天线面板对应的TCI所使用的时域资源,分别为所述一个PUCCH资源对应的频域资源的一部分。
在一个实施例中,不同天线面板对应的TCI所使用的频域资源不重叠,且所述一个PUCCH资源对应的频域资源分配给不同TCI,为多个TCI对应的天线面板提供不重叠的频域资源。
在一个实施例中,所述一个PUCCH资源对应的频域资源按照预先设定的分配规则分配给不同TCI,例如,分配规则可以由PRI配置指示,或者可以在终端中预先存储,或者也可以由基站通过下发RRC信令指示等。
在一个实施例中,基站的不同TRP接收不同天线面板通过各自不同的频域资源上行传输的相同UCI。如此,基于同一PUCCH资源对应的频域资源分配给多个TCI对应的天线面板,可以在占用较 少的PUCCH资源的基础上,完成多传输点协同传输,提升UCI上行传输的传输速率。
本公开实施例提供一种PUCCH的传输方法,由基站执行,可包括:根据预定义的分配图样,确定不同所述天线面板进行所述PUCCH的NC-JT使用的频域资源;

在本公开实施例中,跳频传输指示信息,可以由基站通过PRI指示给终端,也可以由基站通过网络信令发送给终端。
在一个实施例中,以终端中仅包含2个天线面板为例,PUCCH资源对应的频域资源分配给天线面板1和天线面板2。跳频传输指示信息可以指示:根据时隙内跳频(intra-slot Frequency Hopping)的至少一个跳频点对应的PRB确定至少一个天线面板使用的频域资源的起始PRB。其中,时隙内跳频的一个时隙可包含多个跳频点,不同的跳频点对应不同的频段。
在一个实施例中,以终端中仅包含2个天线面板为例,天线面板1的起始PRB可根据PRI指示确定,天线面板2可由跳频起始PRB指示确定为时隙内跳频的第二个跳频点对应的PRB(second Hop PRB)。
由于PUCCH的时隙内跳频对应的至少一个跳频点PRB作为至少一个天线面板的起始PRB,因此通过去使能时隙内跳频,减少上行传输过程中出现时隙内跳频导致天线面板的起始PRB被跳频传输占用,从而可以提升天线面板的PUCCH传输可靠性。
如此,通过跳频传输指示信息携带对天线面板使用的频域资源的起始PRB的指示,基站可以无需构建新的网络信令或者指示信息,从而借用跳频传输指示信息的下发,高效完成对天线面板使用的频域资源的起始PRB的指示,提高信息传输和资源指示的效率。
