非周期SRS资源集的触发方法及设备

本申请主张在2020年1月22日在中国提交的中国专利申请号为202010075487.5的优先权,其全部内容通过引用包含于此。
技术领域
本发明涉及通信领域,尤其涉及一种非周期SRS资源集的触发方法及设备。
背景技术
目前协议中定义的每个信道探测参考信号(Sounding Reference Signal,SRS)资源集中仅支持一种用途(usage),且也仅支持一个非周期的有效时隙(slot)。在无线资源控制(Radio Resource Control,RRC)配置了非周期SRS资源集的有效时隙之后,且在RRC重配之前,对于多个SRS资源集中的有效时隙就固定了,无法更改。若此时配置了多个SRS资源集,网络有可能会在同一个时隙上发送多个下行控制信息(Downlink Control Information,DCI),分别用于触发不同的SRS资源集,此时会造成物理下行控制信道(Physical Downlink Control Channel,PDCCH)资源的拥堵。
若对于可通过信令改变时隙格式(slot format)的情况,在DCI信令发送后,该DCI信令触发的用于发送SRS资源的上行符号或上行slot,有可能会被信令动态修改时隙格式。此时SRS资源无法发送,需要网络重新触发一次,更加深了PDCCH资源的拥堵。
针对上述问题,现有技术中采用基于有效窗的非周期激活方法。即,假设用于触发非周期SRS资源集的DCI发送于slot n,则该SRS资源集会在第n+x+y个有效时隙上发送。其中,n为发送PDCCH的时隙,x为SRS资源集的时隙偏移(slot offset),y为有效窗内的最近的有效时隙。这种方式的缺点在于,如 果有多个SRS资源在同一时隙上被激活,则只有最后一个DCI激活的SRS资源会被传输。
对于天线切换,由于1路发射4路接收(简称1T4R)的天线切换被配置了两个非周期的SRS资源集,且该两个SRS资源集是同时被一个DCI激活。若采用上述基于有效窗的非周期激活方法,则有可能出现本来应该在不同时隙上发送的两个SRS资源集,被挪到了同一个时隙内发送的情况。若在同一个时隙内,则无法完成天线切换,从而导致天线切换失败。
发明内容
本发明实施例提供一种非周期SRS资源集的触发方法及设备,以解决至少一个DCI同时触发多个非周期SRS资源或非周期SRS资源集时,没有相应的时隙级别的时域信息的局限性问题。

第五方面,本发明实施例还提供了一种网络设备,包括:存储器,存储有计算机程序指令;处理器,当所述计算机程序指令被所述处理器执行时实现如上述第一方面所述的非周期SRS资源集的触发方法。
第六方面,本发明实施例还提供了一种终端设备,包括:存储器,存储有计算机程序指令;处理器,当所述计算机程序指令被所述处理器执行时实现如上述第二方面所述的非周期SRS资源集的触发方法。
第七方面,本发明实施例还提供了一种计算机可读存储介质,所述计算机可读存储介质包括指令,当所述指令在计算机上运行时,使得所述计算机执行如上述第一方面或第二方面所述的非周期SRS资源集的触发方法。

下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例是本发明一部分实施例,而不是全部的实施例。基于本发明中的实施例,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,都属于本发明保护的范围。
本发明的技术方案,可以应用于各种通信系统,例如:全球移动通讯系统(Global System of Mobile communication,GSM),码分多址(Code Division Multiple Access,CDMA)系统,宽带码分多址(Wideband Code Division Multiple Access,WCDMA),通用分组无线业务(General Packet Radio Service,GPRS),长期演进(Long Term Evolution,LTE)/增强长期演进(Long Term EvolutionAdvanced,LTE-A),新空口(New Radio,NR)等。
终端设备(User Equipment,UE),也可称之为移动终端(Mobile Terminal)、移动终端设备等,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,用户设备可以是终端设备,如移动电话(或称为“蜂窝”电话)和具有终端设备的计算机,例如,可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置,它们与无线接入网交换语言和/或数据。
网络设备也可称之为基站,可以是GSM或CDMA中的基站(Base Transceiver Station,BTS),也可以是WCDMA中的基站(NodeB),还可以是LTE中的演进型基站(evolutional Node B,eNB或e-NodeB)及5G基站(gNB),本发明并不限定。
以下结合附图,详细说明本发明各实施例提供的技术方案。
图1(a)和图1(b)分别是本发明的一个实施例中一种非周期SRS资源集的触发方法的示意性流程图,该方法可以由电子设备执行,例如网络设备或终端设备。换言之,所述方法可以由安装在网络设备或终端设备的软件或硬件来执行。图1(a)的方法应用于终端设备,可包括:
S102,接收DCI,DCI用于激活非周期的信道探测参考信号SRS单元。
其中,SRS单元包括一个SRS资源集中的多个SRS资源或多个SRS资源集。DCI由网络设备承载于PDCCH上下发。
S104,在激活的SRS单元对应的至少一个有效窗内发送SRS单元。
其中,有效窗内具有至少一个有效时隙。
图1(b)的方法应用于网络设备,可包括:
S106,发送DCI,DCI用于激活非周期的信道探测参考信号SRS单元。
S108,在激活的SRS单元对应的至少一个有效窗内接收SRS单元。
其中,有效窗内具有至少一个有效时隙。
本实施例中,有效窗可由网络设备和终端设备通过协议约定,也可由网络设备配置。SRS单元的时域特性和其所包含的一个SRS资源集中的多个SRS资源或多个SRS资源集的时域特性一致,即均为非周期的。以下各实施例中,所引用的SRS资源集或SRS资源均为非周期的。
在本发明实施例中,终端设备通过接收下行控制信息DCI,并在由DCI激活的非周期的SRS单元对应的至少一个有效窗内发送SRS单元(如至少一个SRS资源集中的多个SRS资源或多个SRS资源集),进而使网络设备能够在激活的SRS单元对应的至少一个有效窗内接收SRS单元。可见,在DCI激 活SRS单元时,SRS单元可在至少一个有效窗内完成发送和接收,因此解决了至少一个DCI同时激活至少一个SRS资源集中的多个SRS资源或多个SRS资源集时导致PDCCH资源拥堵或天线切换失败的问题,实现了DCI激活SRS单元的灵活性。
在一个实施例中,网络设备可配置SRS单元的参数信息。参数信息包含SRS单元对应的时隙偏移。
以下通过多个实施例,分别说明SRS单元包括一个SRS资源集中的多个SRS资源的场景以及SRS单元包括多个SRS资源集的场景。
场景一、SRS单元包括多个SRS资源集。参数信息包括至少一个有效窗以及各SRS资源集对应的时隙偏移。
在一个实施例中,网络设备配置多个SRS资源集的参数信息时,可采用以下方式A1至A3中的任一种来配置多个SRS资源集对应的时隙偏移:
A1、在终端设备仅支持各SRS资源集在同一个有效时隙内发送的情况下,为各SRS资源集配置相同的时隙偏移。
该方式主要针对Rel 17以及之后的终端设备。终端设备仅支持各SRS资源集在同一个有效时隙内发送,相当于终端设备支持扩展的SRS符号数,例如支持14个符号都可以放SRS资源(目前SRS资源只能配置在最后6个符号上)。
A2、为各SRS资源集配置不同的时隙偏移。
A3、为部分SRS资源集配置相同的时隙偏移。即,为多个SRS资源集中的一部分SRS资源集配置相同的时隙偏移,为另一部分SRS资源集配置不同的时隙偏移。
其中,各SRS资源集对应的时隙偏移分别用于指示各SRS资源集的时域位置。SRS资源集的时域位置包括各SRS资源集相对于第二初始时隙的时域位置;或,SRS资源集的时域位置包括SRS资源集序列中的第一个SRS资源集相对于第二初始时隙的时域位置以及各SRS资源集相对于前一个SRS资源集的时域位置。
其中,SRS资源集序列基于以下至少一项确定:各SRS资源集对应的时隙偏移、各SRS资源集中包含的SRS资源的资源标识、各SRS资源中的符号位置。
第二初始时隙与发送DCI的第一初始时隙之间的映射关系为:
Figure PCTCN2021072728-appb-000001
Figure PCTCN2021072728-appb-000002
其中,n为第二初始时隙;m为第一初始时隙;μ SRS对应于SRS单元的子载波间隔,即SRS单元的子载波间隔为
Figure PCTCN2021072728-appb-000003
μ PDCCH对应于PDCCH的子载波间隔,即PDCCH的子载波间隔为

表示上取整,符号
Figure PCTCN2021072728-appb-000006
表示下取整。
在一个实施例中,参数信息还包括用途usage。基于此,网络设备在配置多个SRS资源集的参数信息时,还可为各SRS资源集配置相同的usage。
基于上述实施例中网络设备所采用的时隙偏移配置方式,终端设备可采用以下任一种或多种方式发送SRS资源集:
方式一、终端设备在不同的有效时隙上发送多个SRS资源集。
例如,终端设备在有效时隙1上发送SRS资源集1,在有效时隙2上发送SRS资源集2。
方式二、终端设备在同一有效时隙的不同符号位置上发送至少一个SRS资源集。
例如,终端设备在有效时隙1的符号位置1上发送SRS资源集1,在有效时隙1的符号位置2上发送SRS资源集2。
若采用上述方式一和方式二结合的方式发送SRS资源集,则例如:在有效时隙1的不同符号位置上分别发送SRS资源集1和SRS资源集2,并在有效时隙2的不同符号位置上分别发送SRS资源集3和SRS资源集4。
在一个实施例中,终端设备可按照SRS资源集序列,在有效窗内的至少一个有效时隙上依次发送各SRS资源集。其中,SRS资源集序列基于以下至少一项确定:各SRS资源集对应的时隙偏移、各SRS资源集中包含的各SRS资源 的资源标识、各SRS资源中的符号位置。可选的,SRS资源集序列可按照各项值,如包括各SRS资源集对应的时隙偏移、各SRS资源的资源标识、各SRS资源中的符号位置中的至少一项,由小到大或由大到小的顺序确定。
终端设备按照SRS资源集序列,在至少一个有效时隙上依次发送各SRS资源集时,根据各有效窗的窗起点不同以及各SRS资源集的时隙偏移的偏移起点不同,可采用不同的发送方式发送各SRS资源集。
方式一、终端设备在第n+x u+y u个有效时隙上发送第u个SRS资源集;n为第二初始时隙;x u为第u个SRS资源集对应的时隙偏移;y u为第u个SRS资源集对应的有效时隙相对于第二初始时隙和第u个SRS资源集的时隙偏移。
该方式一中,各SRS资源集对应至少一个有效窗,各有效窗均以第二初始时隙为窗起点;或,各有效窗中的第一个有效窗以第二初始时隙为窗起点,其它各有效窗分别以前一个有效窗的结束位置为窗起点;或,各有效窗中的第一个有效窗以第二初始时隙为窗起点,其它各有效窗分别以前一个SRS资源集对应的有效时隙为窗起点。
