Description

传输参数处理方法及装置 技术领域
本公开涉及无线通信技术领域,例如涉及一种传输参数处理方法及装置。
背景技术
在长期演进(Long Term Evolution,LTE)系统中,仅仅考虑支持一个天线面板(Antenna panel)以及比较少的天线单元(Antenna Element)数目,比如2个天线单元和4个天线单元。上行测量导频探测参考信号(Sounding Reference Signal,SRS)是非预编码的,由天线单元直接映射到天线端口(port)。因此上行传输比较简单。在5G无线接入(5G NR)中,由于可能支持更多的天线单元,如最多支持到32个天线单元,可能支持更多的port,除了1、2和4个天线端口,还需要支持更多的端口数目,可能支持终端多种射频波束的接收,可能支持上行的子带预编码,因此,上行多输入多输出(Multiple-Input Multiple-Output,MIMO)传输比LTE中要复杂很多。
在5G NR中,上行MIMO传输的设计面临较大的技术挑战,一个重要的问题是物理层信令开销过大的问题。仅在预编码相关的参数方面就有明显的信令开销增加。比如:由于码本更加复杂,量化精度需求更高,对应的预编码矩阵指示(Pre-coding Matrix Indication,PMI)信令开销会明显增加;由于支持的传输层数增加,对应的秩指示(rank indication,RI),及PMI的指示开销也会增加;由于支持子带的PMI指示,相比于宽带的PMI反馈,也会明显的增加信令的开销。另一方面,控制信令开销的增加会影响控制信令传输的鲁棒性,并且会引起传输效率的下降。

按照SRS所属的时域符号组或Slot组划分,如图8所示;
按照SRS resource划分。
在一实施例中,M套SRS resource在信令配置时,对应的信令可以是不同的,有的SRS resource可以是周期的,有的SRS resource可以是非周期的,还有的SRS resource可以在指定的时间范围内是周期的。每套SRS resource的端口数目、发送的功率、发送的时频资源位置、使用的发送波束、发送天线和发送通道也可以是不同的。
本实施例中,可以按照SRS resource的配置来进行SRS资源子集划分。
本实施例中SRS resource是一个狭义的概念,主要是针对信令配置上的一些区别来进行区分。而SRS资源中的资源指的是一个广义概念,包括时域资源如符号、时隙等,频域资源如子载波,子带等、空域资源如发送波束资源、发送天线资源和发送天线panel资源,发送通道资源等。
上面几种划分SRS资源子集的方式是可以结合的,比如可以基于SRS resource进行划分后,根据端口和时域资源中的至少之一进行划分等。
在步骤710中,基站确定Y个传输资源组。其中,Y个传输资源组用于一个或多个上行传输编码块的传输。这些上行传输编码块可以在同一个控制信令中被调度。
在一实施例中,Y个传输资源组可以根据传输层来划分,比如,第1、2层为一组,第3、4层为另一组;Y个传输资源组也可以存在交集,比如:第1、2层为第一组,第2、3层为第二组等。
在一实施例中,Y个传输资源组可以根据天线划分或天线panel划分,比如:第一组对应1-8个天线阵子,第二组对应9-16天线阵子等。其中,这些天线阵子组可以发送相同的层,也可以发送不完全相同的层,还可以发送完全不同的层。其中,这些天线阵子组可以在相同的时频资源上发送,也可以在不完全相同的时频资源上发送,还可以在完全不同的时频资源上发送。这些天线子阵组的发送功率可以相同也可以不同,这些天线子阵组的发送波束可以相同也可以不同。
在一实施例中,Y个传输资源组可以根据传输(收发)通道划分,不同的 组可以发送相同的层,也可以发送不完全相同的层,还可以发送完全不同的层。或者,不同的组可以在相同的时频资源上发送,也可以在不完全相同的时频资源上发送,还可以在完全不同的时频资源上发送。不同的组的发送功率可以相同也可以不同,不同的组的发送波束可以相同也可以不同。
在一实施例中,Y个传输资源组还可以按照时频资源进行划分。其中,不同组的时频资源不完全相同。
在一实施例中,Y个传输资源组也可以按照发送波束资源来进行划分。其中,不同组的发送波束不完全相同。
在步骤720中,基站向终端发送X个SRS资源子集的指示信息。其中,X个SRS资源子集用于确定Y个传输资源组的传输参数。
在一实施例中,SRS资源子集的指示信息由高层配置和物理层信令中的至少之一来指示。
在一实施例中,SRS资源子集指示信息可以包括以下一种或多种:
SRS资源索引(SRS resource index,SRI)、SRS端口组标识(SRS port group ID,SGI)、SRS时域位置和X的取值。
在一实施例中,Y的取值由收发端如基站与终端之间约定,如Y=X;或者,Y的取值由基站配置。
在一实施例中,X个SRS资源子集和Y个传输资源组的对应关系由收发端如基站与终端之间约定或由基站配置,如图9所示。
在步骤730中,基站针对X个SRS资源子集和Y个传输资源组的至少之一,分别配置对应的传输参数指示信息。
在一实施例中,传输参数指示信息包括以下至少之一:DMRS端口分配指示信息(也可以认为是层映射指示信息)和编码块(Coding Block,CB)或编码块组(Coding Block Group,CBG)配置信息。
在一实施例中,传输参数指示信息还可以包括传输层数指示信息和预编码指示信息中的至少之一。
本实施例还提供一种传输参数处理装置,包括处理器、存储器以及存储在存储器上可在处理器上运行的计算机程序:基站从SRS资源中选择X个SRS资 源子集;基站确定Y个传输资源组,所述Y个传输资源组用于一个或多个上行传输编码块的传输;基站向终端发送X个SRS资源子集的指示信息。其中,X个SRS资源子集用于Y个传输资源组的传输参数确定;基站针对X个SRS资源子集和Y个传输资源组的至少之一,分别配置对应的传输参数指示信息。
本实施例再提供一种基站,包括上述任意的传输参数处理装置。
本实施例还提供一种计算机可读存储介质,所述计算机可读存储介质上存储有计算机程序,所述计算机程序被处理器执行时实现以下步骤:基站从SRS资源中选择X个SRS资源子集;基站确定Y个传输资源组,所述Y个传输资源组用于一个或多个上行传输编码块的传输;基站向终端发送X个SRS资源子集的指示信息。其中,X个SRS资源子集用于Y个传输资源组的传输参数确定;基站针对X个SRS资源子集和Y个传输资源组的至少之一,分别配置对应的传输参数指示信息。
图10为又一实施例提供的传输参数处理方法的流程示意图,如图10所示,该方法包括以下步骤:
在步骤1000中,终端从SRS资源中确定X个SRS资源子集;其中,X为大于或等于1的自然数。
在一实施例中,SRS resource对应的传输参数可以由基站配置,也可以由终端确定。其中,可以由终端确定的传输参数包括以下至少之一:功率、预编码或发送波束、发送天线和发送通道等。其中,可以由基站确定的参数包括以下至少之一:时频资源、功率、预编码选择范围和发送波束方向范围等。
在一实施例中,X个SRS资源子集用于确定数据信道或控制信道传输参数。其中,根据SRS的传输参数确定数据信道的传输参数;或者,根据SRS的传输参数确定控制信道的传输参数。
在一实施例中,确定X个SRS资源子集包括:
终端根据约定的SRS资源子集合的划分方式确定X个SRS资源子集;
或者,终端根据来自基站的配置信令指示的SRS资源子集的划分方式确定X个SRS资源子集。
在步骤1010中,终端确定Y个传输资源组及对应的传输资源;其中,所述 Y个传输资源组用于一个或多个上行传输编码块的传输,Y为大于或等于1的自然数。
在一实施例中,Y个传输资源组可以根据预先约定确定;
在一实施例中,Y个传输资源组也可以根据基站配置确定。
在步骤1020中,终端确定X个SRS资源子集和Y个传输资源组的对应关系。
在一实施例中,终端可以根据预先约定确定或基站配置确定X个SRS资源子集和Y个传输资源组的对应关系。
在步骤1030中,终端根据X个SRS资源子集确定Y个传输资源组的传输参数。
比如:终端针对X个SRS资源子集,如SRI或SGI指示的资源或组(resource/group),分别确定对应的传输层或DMRS ports。
在一实施例中,X=2时,如图11所示,根据SRI1关联的TRI1,确定其使用的层数r1,映射到层1......r1;DMRS port为p1......(p1+r1);根据SRI2关联的TRI2,确定其使用的层数r2,映射到层[(p2-p1)+1]......[(p2-p1)+r1];DMRS port为p2+1......(p2+r2)。X>2的情况以此类推,这里不再赘述。
其中,p1和p2的取值,以及p1和p2的关系可以约定或者由基站配置。例如,在约定的方式中,可以是:p1=p2+r1,或者p1=p2。
这里,SRI只是一种SRS资源子集划分的例子,其它资源子集划分方式的情况也与此类似。
再如:终端针对X个SRS资源子集,如SRI或SGI指示的resource或group,分别确定对应的CB或CBG。每个resource或group可以对应一个或多个CB或CBG;对应方式确定的规则可以是基站配置的或者预先约定的。同一个CBG可以对应1个或多个resource/group关联的层。
又如:终端针对Y个传输资源组,例如,panel 1......panel Y,天线1......天线Y,发送波束1......发送波束Y,分别确定对应的传输层或DMRS ports,功率,预编码,CB或CBG配置;其它传输资源组的划分方式的情况也与此类似。
本实施例还提供一种传输参数处理装置,包括处理器、存储器以及存储在存储器上可在处理器上运行的计算机程序:从SRS资源中确定X个SRS资源子集;其中X为大于或等于1的自然数;确定Y个传输资源组及对应的传输资源;其中,Y为大于或等于1的自然数;确定X个SRS资源子集和Y个传输资源组的对应关系;根据所述X个SRS资源子集确定Y个传输资源组的传输参数。
本实施例还提供一种终端,包括上述任意的传输参数处理装置。
本实施例还提供一种计算机可读存储介质,所述计算机可读存储介质上存储有计算机程序,所述计算机程序被处理器执行时实现以下步骤:从SRS资源中确定X个SRS资源子集;其中X为大于或等于1的自然数;确定Y个传输资源组及对应的传输资源;其中,Y为大于或等于1的自然数;确定X个SRS资源子集和Y个传输资源组的对应关系;根据所述X个SRS资源子集确定Y个传输资源组的传输参数。
通过图7和图10所示的传输参数处理方法,实现了将原本的N1+N2维的码本拆分为2个低维的码本用于反馈。这样,每个码本对应的port group或resource对应的信道可以具有比较典型的特征,比如,码本来自同一个panel,或者来自同一极化方向,或者采用相同的射频波束,或者采用相同的波速(beam)。这样使得码本维度变小了,且对应的码本特性较明显,能够有效利用这些特征来构造码本,提高了量化效率,从而达到了相同性能所需要的PMI开销小的目的。
