本申请主张在2019年1月4日在中国提交的中国专利申请号No.201910009135.7的优先权,其全部内容通过引用包含于此。
技术领域
本公开涉及通信应用的技术领域,尤其涉及一种信息传输方法、基站及终端。
背景技术
在NR Rel-15系统中,非周期CSI(Channel State Information,信道状态信息)通过PUSCH(Physical Uplink Shared Channel,物理上行共享信道)传输。基站通过DCI格式1_0中的CSI request字段来通知UE(User Equipment,用户设备)是否进行非周期性CSI上报。
DCI格式1_0的CSI request字段可能为0,1,2,3,4,5或6比特。当CSI request全部为0时,不触发任何CSI上报。否则,根据高层配置信息上报非周期CSI。基站可以触发非周期CSI上报和上行数据一起进行传输,也可以仅触发非周期CSI上报。基站可以通过高层信令配置使用周期的信道状态信息参考信号CSI-RS、半持续的CSI-RS或者非周期的CSI-RS进行测量。
DCI格式1_0中包含时域资源分配信息和频域资源分配信息,非周期CSI和数据(如果有的话)在DCI格式1_0所指示的资源上进行传输。当DCI和非周期CSI在同一个时隙中时,非周期CSI的参考资源为DCI发送的时隙,否则,非周期CSI的参考资源为满足CSI处理时延且和CSI上报时隙距离最近的有效下行时隙。
在NR Rel-16系统中,如果支持通过下行DCI触发短PUCCH(Physical Uplink Control Channel,物理上行控制信道)格式传输非周期CSI,可能会存在多个下行DCI同时指示在同一个PUCCH资源中进行非周期CSI上报的情况,这时,根据目前标准的定义还没有具体的CSI传输方案。

具体实施方式
为使本公开要解决的技术问题、技术方案和优点更加清楚,下面将结合附图及具体实施例进行详细描述。
如图1所示,为本公开一些实施例提供了一种信息传输方法,应用于基站,包括:
步骤101:发送用于指示终端上报非周期信道状态信息CSI的第一下行下行控制信息DCI,所述第一下行DCI调度的物理下行共享信道PDSCH对应的混合自动重传请求确认HARQ-ACK和所述第一下行DCI指示终端上报的非周期CSI在同一个物理上行控制信道PUCCH资源中传输;
本步骤中,下行DCI包括CSI触发信息域,该CSI触发信息域用于指示终端是否上报非周期CSI。具体的,可通过对CSI触发信息域所占比特位的不同赋值来指示终端是否上报非周期CSI。
比如,CSI触发信息域所占比特位为两个,若比特信息为“00”,则用于指示终端不上报非周期CSI;若比特信息为“10”用于指示终端上报非周期 CSI。
这里,第一下行DCI中的CSI触发信息域指示终端上报非周期CSI。
步骤102:接收终端在所述PUCCH资源发送的HARQ-ACK和非周期CSI。
本公开一些实施例的信息传输方法,通过发送用于指示终端上报非周期信道状态信息CSI的第一下行下行控制信息DCI,所述第一下行DCI调度的物理下行共享信道PDSCH对应的混合自动重传请求确认HARQ-ACK和所述第一下行DCI指示终端上报的非周期CSI在同一个物理上行控制信道PUCCH资源中传输;接收终端在所述PUCCH资源发送的HARQ-ACK和非周期CSI,如此,能够通过PUCCH格式传输非周期CSI,减少下行控制开销,降低非周期CSI的传输时延。
可选地,在本公开一些实施例中,在步骤102之前,所述方法还可以包括以下步骤:
确定信道状态信息参考信号CSI-RS的目标发送时隙,在所述目标发送时隙中发送CSI-RS。
这里,终端可基于基站发送的该CSI-RS进行CSI测量。
这里,本步骤中的确定信道状态信息参考信号CSI-RS的目标发送时隙,可以具体包括以下两种实现方式。
方式一:
根据高层信令配置或者预定义的值确定非周期CSI上报时隙与CSI测量资源之间的最小时隙间隔;
将与所述非周期CSI上报时隙间隔大于或者等于所述最小时隙间隔的有效下行时隙中与所述非周期CSI上报时隙距离最近的有效下行时隙确定为CSI-RS的目标发送时隙。
可选的,所述有效下行时隙至少包括一个高层信令配置的下行符号或者灵活符号,所述灵活符号包括上行符号和/或下行符号;或者,所述有效下行时隙不包含在终端的测量间隔内。
方式二:
根据所述第一下行DCI的CSI触发信息域,确定CSI-RS的目标发送时隙。
具体的,本步骤中还可以具体包括以下步骤:
若所述第一下行DCI为至少两个,且每个所述第一下行DCI的CSI触发信息域指示的比特信息相同,则将每个所述第一下行DCI指示的CSI-RS的发送时隙确定为CSI-RS的目标发送时隙;
也就是说,每个第一下行DCI的CSI触发信息域中指示相同的比特信息,且每个第一下行DCI的CSI触发信息域对应的CSI-RS偏移时隙为0,则将每个第一下行DCI指示的CSI-RS的发送时隙,即每个第一下行DCI所在的时隙确定为CSI-RS的目标发送时隙,即在每个第一下行DCI指示的CSI-RS传输时隙中都传输CSI-RS。
若所述第一下行DCI为至少两个,每个所述第一下行DCI的CSI触发信息域指示的比特信息不同,且所述至少两个不同的CSI触发信息域中指示同一个时隙内的CSI-RS,则将所述同一个时隙确定为CSI-RS的目标发送时隙。
需要说明的是,不同的CSI触发信息域指示相同的CSI上报信息(如上报CSI格式、CSI比特数等)但不同的CSI-RS时隙偏移。
这里,在不同的CSI触发信息域指示同一个时隙内的CSI-RS,则该同一个时隙即为CSI-RS的目标发送时隙。
可选的,所述第一下行DCI满足CSI处理时延;
其中,所述满足CSI处理时延的第一下行DCI为DCI的结束位置与所述PUCCH资源的起始位置大于或者等于CSI处理时间。
需要说明的是,DCI的结束位置具体是指该传输DCI所占用资源的结束位置。
进一步地,在本公开一些实施例中,所述方法还可包括:
若存在除所述第一下行DCI外第二下行DCI调度的PDSCH对应的HARQ-ACK和所述第一下行DCI调度的PDSCH对应的HARQ-ACK在同一个PUCCH资源反馈,将所述第二下行DCI中不满足CSI处理时延的DCI中的CSI触发信息域所占比特均设为零或者设为任意值。
为了避免终端漏检所有指示非周期CSI上报的DCI,在本公开一些实施例中,若存在除所述第一下行DCI外的第二下行DCI时,所述第一下行DCI所指示的PUCCH资源与所述第二下行DCI所指示的PUCCH资源不同;
其中,所述第二下行DCI为与所述第一下行DCI调度的PDSCH的HARQ-ACK 在所述同一个PUCCH资源上反馈的其他PDSCH对应的DCI。
基于上述存在除所述第一下行DCI外的第二下行DCI时,进一步地,所述方法还可包括:
在所述第一下行DCI中最晚发送的第一下行DCI所指示的PUCCH资源上检测反馈信息,若检测到第一传输内容,则按照HARQ-ACK以及CSI的比特数进行解调;
若未检测到所述第一传输内容,则在所述第二下行DCI中最晚发送的第二下行DCI所指示的PUCCH资源上检测反馈信息,若检测到第二传输内容,则按照HARQ-ACK的比特数进行解调。
需要说明的是,这里的HARQ-ACK包括:第一下行DCI调度的PDSCH对应的HARQ-ACK和第二下行DCI调度的PDSCH对应的HARQ-ACK。
下面就一示例具体说明本公开方法的实现过程。
如图2所示,假设基站使用时隙调度,在slotn调度了PDSCH传输,通过下行DCI指示在slot n+4中传输所述PDSCH的HARQ-ACK反馈信息。
在slot n+1中,基站调度了PDSCH传输并且触发终端传输非周期CSI,通过下行DCI指示在slot n+4中传输所述PDSCH的HARQ-ACK反馈信息和非周期CSI信息。
如果基站在slot n+2和/或slot n+3中还要调度PDSCH,并且仍然通过下行DCI指示PDSCH对应的HARQ-ACK信息和slot n和slot n+1中PDSCH对应的HARQ-ACK信息在同一个PUCCH进行复用反馈,且基站设置slot n+2的调度DCI中也触发非周期CSI传输时,可采用如下三种方式确定传输CSI-RS的时隙。
第一种方式:
基站基于非周期CSI上报时隙确定CSI-RS传输时隙,由于下行DCI触发slot n+4中的非周期CSI上报,且基站指示非周期CSI上报时隙和CSI测量资源之间的最小时隙间隔为2,则对应的CSI-RS传输时隙为n+2。
这里,该方式可具体对应上述确定信道状态信息参考信号CSI-RS的目标发送时隙的实现方式中的方式一。
第二种方式:
基站在slot n+2和slot n+1的CSI触发信息域中指示相同的比特信息,假设CSI触发信息域对应的CSI-RS偏移时隙为0,则基站在slot n+1和slot n+2中均发送CSI-RS。
第三种方式:
基站在slot n+2和slot n+1的CSI触发信息域中指示不同的比特信息,均指示终端在slot n+4同一个PUCCH资源进行相同非周期CSI上报,区别在于slot n+1中CSI触发信息域对应的CSI-RS偏移时隙为1,slot n+2中CSI触发信息域对应的CSI-RS偏移时隙为0,则基站仅在slot n+2中发送CSI-RS。
这里,第二种方式和第三种方式对应上述确定信道状态信息参考信号CSI-RS的目标发送时隙的实现方式中的方式二。
另外,假设slot n+3无法满足CSI处理时延,基站可以将slot n+3的调度下行DCI的CSI触发信息域比特设置为全0,基站也可以选择将slot n+3的调度下行DCI的CSI触发信息域比特设置为任意值,这时终端将忽略不满足CSI处理时延的下行DCI中的CSI触发信息域内容。
为了避免终端漏检所有指示非周期CSI上报的DCI,基站可以在slot n和slot n+1/n+2和slot n+3对应的下行DCI中分别指示不同的PUCCH资源,例如,基站在slot n的下行DCI中指示终端使用PUCCH资源1,在slot n+1/n+2对应的下行DCI中指示终端使用PUCCH资源2,在slot n+3对应的下行DCI中指示终端使用PUCCH资源3。
这样,如果终端漏检slot n+1/n+2的下行DCI,终端仅在slot n+4的PUCCH资源3上反馈HARQ-ACK信息。
如果终端接收到所有DCI,终端在slot n+4的PUCCH资源2上反馈HARQ-ACK和CSI信息。
如果终端漏检slot n+1/n+2/n+3的下行DCI,终端仅在slot n+4的PUCCH资源1上反馈HARQ-ACK信息,基站可以通过盲检不同的PUCCH资源确定终端是否存在下行DCI的漏检情况。
本公开一些实施例的信息传输方法,通过发送用于指示终端上报非周期信道状态信息CSI的第一下行下行控制信息DCI,所述第一下行DCI调度的物理下行共享信道PDSCH对应的混合自动重传请求确认HARQ-ACK和所述第一 下行DCI指示终端上报的非周期CSI在同一个物理上行控制信道PUCCH资源中传输;接收终端在所述PUCCH资源发送的HARQ-ACK和非周期CSI,如此,能够通过PUCCH格式传输非周期CSI,减少下行控制开销,降低非周期CSI的传输时延。
如图3所示,为本公开一些实施例提供了一种信息传输方法,应用于终端,包括:
步骤301:接收基站发送的第一下行DCI,所述第一下行DCI用于指示终端上报非周期CSI,且所述第一下行DCI调度的PDSCH对应的HARQ-ACK和所述第一下行DCI指示终端上报的非周期CSI在同一个PUCCH资源中传输;
本步骤中,下行DCI包括CSI触发信息域,该CSI触发信息域用于指示终端是否上报非周期CSI。具体的,终端可通过对CSI触发信息域所占比特位的不同赋值来确定是否上报非周期CSI。
比如,CSI触发信息域所占比特位为两个,若比特信息为“00”,则用于指示终端不上报非周期CSI;若比特信息为“10”用于指示终端上报非周期CSI。
步骤302:在所述PUCCH资源上发送的HARQ-ACK和非周期CSI。
本公开一些实施例的信息传输方法,通过接收基站发送的第一下行DCI,所述第一下行DCI用于指示终端上报非周期CSI,且所述第一下行DCI调度的PDSCH对应的HARQ-ACK和所述第一下行DCI指示终端上报的非周期CSI在同一个PUCCH资源中传输;在所述PUCCH资源上发送的HARQ-ACK和非周期CSI,如此,能够通过PUCCH格式传输非周期CSI,减少下行控制开销,降低非周期CSI的传输时延。
需要说明的是,终端忽略不满足CSI处理时延的下行DCI中的CSI触发信息域内容。
在本公开一些实施例中,在步骤302之前,所述方法还包括:
根据所述第一下行DCI的CSI触发信息域,确定CSI上报时隙。
进一步地,所述方法还包括:
确定CSI测量资源。
这里,在确定CSI测量资源后,终端在该测量资源上进行CSI测量,并 在CSI上报时隙上进行CSI上报。
具体的,本步骤中确定CSI测量资源可以包括以下三种实现方式。
方式A,根据所述CSI上报时隙,确定CSI测量资源。
方式B,根据预定义的CSI处理时间,确定非周期CSI上报时隙与CSI测量资源之间的最小时隙间隔;
将与所述非周期CSI上报时隙间隔大于或者等于所述最小时隙间隔的有效下行时隙中与所述非周期CSI上报时隙距离最近的有效下行时隙确定为CSI测量资源。
优选地,述有效下行时隙至少包括一个高层信令配置的下行符号或者灵活符号或者CSI-RS,所述灵活符号包括上行符号和/或下行符号;
或者,所述有效下行时隙不包含在终端的测量间隔内。
需要说明的是,终端根据DCI指示确定在有效下行时隙中是否包含CSI-RS。
方式C,将接收到的所述第一下行DCI中最晚发送的第一下行DCI所在的时隙确定为CSI测量资源。
这里继续以图2所示的示例为例,终端在确定slot n+4中传输的非周期CSI的参考资源时,终端选择满足CSI处理时延且和CSI上报时隙距离最近的有效下行时隙,假设CSI处理时延为30个符号,一个时隙中包含14个符号,PUCCH2占用slot n+4中的最后3个符号,基站通过下行DCI指示终端在slot n+1和slot n+2中均存在CSI-RS或者基站通过下行DCI指示终端在slot n+2中存在CSI-RS,则终端将slot n+2作为非周期CSI的参考子帧;或者,假设高层信令配置非周期CSI上报时隙和CSI测量资源之间的最小时隙间隔为3,则终端使用slot n+1作为非周期CSI的参考子帧;或者,终端认为触发在一个PUCCH中反馈CSI的下行DCI所在时隙都能够满足CSI处理时延,终端将最后一个触发非周期CSI上报的slot n+2作为非周期CSI的参考子帧。
本公开一些实施例的信息传输方法,通过发送用于指示终端上报非周期信道状态信息CSI的第一下行下行控制信息DCI,所述第一下行DCI调度的物理下行共享信道PDSCH对应的混合自动重传请求确认HARQ-ACK和所述第一 下行DCI指示终端上报的非周期CSI在同一个物理上行控制信道PUCCH资源中传输;接收终端在所述PUCCH资源发送的HARQ-ACK和非周期CSI,如此,能够通过PUCCH格式传输非周期CSI,减少下行控制开销,降低非周期CSI的传输时延。
如图4所示,本公开一些实施例还提供一种基站,包括:收发机410、存储器420、处理器400及存储在存储器上并可在处理器上运行的计算机程序,所述处理器400执行所述计算机程序时实现以下步骤:
