下面结合基站和终端两侧对本公开一些实施例提供的所述非周期信道状态信息CSI的传输方法进行进一步说明。
针对上述技术问题,本公开一些实施例提供了一种非周期信道状态信息CSI的传输方法,其中涉及的基站侧,主要是:基站通过调度PDSCH传输的DCI(即上述下行DCI)中的字段指示UE(终端)是否上报非周期CSI,以及接收使用同一个PUCCH资源反馈的所述DCI对应的HARQ-ACK反馈和所述非周期CSI,并且,在一个PUCCH资源所对应的多个下行DCI中,如果基站在其中一个DCI中触发了非周期CSI上报,则后续DCI(对应于同一个PUCCH资源的、排序(参见下述排序方式)在触发了非周期CSI上报的DCI之后的DCI)的CSI触发信息域也指示所述终端在所述PUCCH资源上报非周期CSI,基站可以设置后续所有DCI中的CSI触发信息域的内容与触发了非周期CSI上报的DCI的CSI触发信息域的内容相同。
其中,具体的,以下行DCI中的字段指示UE上报非周期CSI为例:
关于终端侧:
终端接收基站发送的下行DCI,根据所述DCI中的CSI触发信息上报非周期CSI,所述DCI对应的HARQ-ACK和所述DCI触发的非周期CSI使用同一个PUCCH资源进行反馈。如果终端接收到(需要)在同一个PUCCH资源上进行反馈的多个PDSCH(物理下行共享信道),当终端收到其中一个PDSCH对应的第一DCI中触发非周期CSI反馈时,则终端不期望在所述第一DCI之后的其它DCI中包含的CSI触发信息域的内容指示不上报非周期CSI,或者终端不期望在所述第一DCI之后的其它DCI中包含的CSI触发信息域的内容和第 一DCI中的CSI触发信息域的内容不同,所述其它DCI为和第一DCI调度的PDSCH的HARQ-ACK在相同PUCCH资源反馈(HARQ-ACK)的其它PDSCH对应的DCI。
进一步的,还包括:当所述第一DCI之前存在另外的DCI时,第一DCI指示的PUCCH资源和所述另外的DCI所指示的PUCCH资源不同。
本公开一些实施例中可根据如下方式确定非周期CSI的参考时隙(具体的,CSI需要进行测量和上报,测量资源对应于参考时隙):
当最后一个DCI和非周期CSI的PUCCH资源在同一个时隙中时,非周期CSI的参考时隙为最后一个DCI发送的时隙,否则,非周期CSI的参考时隙为满足CSI处理时延且和CSI上报时隙距离最近的有效下行时隙;
或者,非周期CSI的参考时隙为满足CSI处理时延且和CSI上报时隙距离最近的有效下行时隙;
或者,非周期CSI的参考时隙为最后一个的DCI所在的时隙;
其中,有效下行时隙是指至少包含一个高层信令配置的下行符号或灵活符号,且不包含在UE的测量间隔内的下行时隙。
进一步的,终端根据确定的非周期CSI的参考时隙,进行CSI测量,得到非周期CSI;
然后终端根据最后一个DCI的指示确定PUCCH资源,在所述PUCCH资源上发送得到的非周期CSI以及各个DCI调度的PDSCH的HARQ-ACK。
在此说明:上述内容中,在同一个PUCCH资源进行反馈的DCI首先按照载波编号的升序进行排序(一个载波上可能存在多个DCI),然后按照检测机会的起始时刻或者结束时刻(即DCI在传输资源范围内的起始时刻或者结束时刻)进行排序。最后一个DCI为接收到的在同一个PUCCH资源进行反馈的DCI中的最后一个。判断DCI的顺序时,均根据上述方式对DCI进行排序。下同。
关于基站侧:
基站通过下行DCI中的CSI触发信息域指示UE上报非周期CSI,以及指示所述DCI对应的HARQ-ACK和所述DCI触发的非周期CSI使用同一个PUCCH资源进行反馈。如果基站调度了(需要)在同一个PUCCH资源上进行反馈的 多个PDSCH,当基站在其中一个PDSCH对应的第一DCI中触发非周期CSI反馈时,则在所述第一DCI之后的其它DCI的CSI触发信息域也指示所述终端在所述PUCCH资源上报非周期CSI,或者在所述第一DCI之后的其它DCI中包含的CSI触发信息域的内容和第一DCI中的CSI触发信息域的内容相同,所述其它DCI为和第一DCI调度的PDSCH的HARQ-ACK在相同PUCCH资源反馈(HARQ-ACK)的其它PDSCH对应的DCI。
进一步的,还包括:当所述第一DCI之前存在另外的DCI时,第一DCI指示的PUCCH资源和所述另外的DCI所指示的PUCCH资源不同。
本公开一些实施例中,基站根据最后一个DCI的指示确定PUCCH资源,在所述PUCCH资源上检测所述终端反馈的非周期CSI和HARQ-ACK。
进一步的,如果基站在上述PUCCH资源中没有检测到所述终端反馈的非周期CSI和HARQ-ACK,且基站在最后一个DCI之前的DCI中指示了不同的PUCCH资源,则基站按照DCI倒序在对应的不同PUCCH资源上进行检测,直到检测到有效反馈信息(在非不连续发送DTX状态下认为检测到存在数据传输,确认检测到有效反馈信息)。
在此说明:上述内容中,在同一个PUCCH资源进行反馈的DCI首先按照载波编号的升序进行排序,然后按照检测机会的起始时刻或者结束时刻时间顺序进行排序。最后一个DCI为发送的在同一个PUCCH资源进行反馈的DCI中的最后一个。判断DCI的顺序时,均根据上述方式对DCI进行排序。同上。
下面对本公开一些实施例提供的方案进行具体举例说明:
假设基站使用本时隙(是指PDCCH与PDSCH在同一时隙)调度,如图3所示,基站在slot(时隙)n调度了PDSCH传输,通过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UE传输非周期CSI,通过DCI指示在slot n+4中传输所述PDSCH的HARQ-ACK反馈和非周期CSI信息。如果基站在slot n+2和/或slot n+3中还要调度PDSCH(slot n、slot n+1、slot n+2以及slot n+3调度的PDSCH不同),并且仍然指示PDSCH对应的HARQ-ACK信息与slot n和slot n+1调度的PDSCH对应的HARQ-ACK信息在slot n+4进行复用反馈时,基站需要设置slot n+2和/或slot n+3的调度DCI中的非周期CSI触发信息域也指示所 述UE上报非周期CSI,或者设置slot n+2和/或slot n+3的调度DCI中的非周期CSI触发信息域的内容和slot n+1的调度DCI中的非周期CSI触发信息域的内容相同。
同时,为了避免UE漏检所有指示非周期CSI上报的DCI,基站可以在slotn对应的DCI中指示不同于slot n+1、slot n+2以及slot n+3分别对应的DCI中所指示的PUCCH资源(具体的,slot n+1、slot n+2以及slot n+3分别对应的DCI所指示的PUCCH资源可以相同,也可以不同,但均与slot n对应的DCI所指示的PUCCH资源不同),例如,基站在slot n的DCI中指示UE使用PUCCH资源1(对应于图3中的标号1),在slot n+1、slot n+2以及slot n+3分别对应的DCI中指示UE使用PUCCH资源2(对应于图3中的标号2),这样如果UE漏检slot n+1、slot n+2以及slot n+3的DCI,则UE仅在slot n+4的PUCCH资源1上反馈HARQ-ACK信息;如果UE接收到所有DCI,则UE在slot n+4的PUCCH资源2上反馈slot n、slot n+1、slot n+2以及slot n+3的HARQ-ACK和CSI信息,基站可以通过盲检不同的PUCCH资源确定UE是否存在DCI的漏检情况。
在确定slot n+4中传输的非周期CSI的参考时隙时,UE将最后一个触发非周期CSI上报的slot n+3作为非周期CSI的参考时隙(这种情况下需确定所有的时隙都满足CSI处理时延);或者,UE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作为非周期CSI的参考时隙,假设CSI处理时延为30个符号,一个时隙中包含14个符号,PUCCH资源2占用slot n+4中的最后3个符号,则UE将slot n+2作为非周期CSI的参考时隙。
由上可知,目前在NR(新空口,5G)中,如何通过PUCCH格式传输非周期CSI还没有具体的方案,而本公开一些实施例提供的方案通过下行相关的DCI中的字段指示UE是否上报非周期CSI,以及指示上报时所述DCI对应的HARQ-ACK反馈和所述非周期CSI使用同一个PUCCH资源进行反馈,并且,在一个PUCCH资源所对应的多个下行DCI中,如果基站在其中一个DCI中触发了非周期CSI上报,则后续所有DCI中的CSI触发信息域也指示所述终端上报非周期CSI,或者后续所有DCI中的CSI触发信息域的内容与触发了非周期CSI上报的DCI的CSI触发信息域的内容相同;能够降低或者避免UE漏检 一个触发非周期CSI上报的DCI时对反馈信息内容的影响,保证非周期CSI在PUCCH上进行可靠反馈。

实际上,可执行代码模块可以是单条指令或者是许多条指令,并且甚至可以分布在多个不同的代码段上,分布在不同程序当中,以及跨越多个存储器设备分布。同样地,操作数据可以在模块内被识别,并且可以依照任何适当的形式实现并且被组织在任何适当类型的数据结构内。所述操作数据可以 作为单个数据集被收集,或者可以分布在不同位置上(包括在不同存储设备上),并且至少部分地可以仅作为电子信号存在于***或网络上。
