请参考图2,其示出了本公开一个实施例提供的资源配置方法的流程图。该 方法可以应用于图1所示的通信系统中。该方法包括如下步骤。
步骤210,网络设备向终端设备发送第一资源配置信息,第一资源配置信息用于指示第一参考信号的传输资源,第一参考信号为定位用途参考信号;其中,传输资源中的频域资源包括至少一个载波。
第一参考信号为定位用途参考信号,用于实现定位,例如,用于实现对终端设备等的定位。基于此,第一参考信号又可以称为“定位用途的参考信号”,本申请实施例为了便于描述,将其统称为第一参考信号。本申请实施例对第一参考信号的类型不作限定,其既可以实现为上行信号,也可以实现为下行信号。在一个示例中,第一参考信号包括以下至少一项:PRS、SRS。可选地,PRS实现为下行信号,SRS实现为上行信号。
为了使得终端设备获知第一参考信号的传输资源,网络设备向终端设备发送第一资源配置信息,该第一资源配置信息即用于指示第一参考信号的传输资源。本申请实施例中,为了提升定位精度,第一参考信号基于载波聚合的方式传输,也即,第一参考信号的传输资源中的频域资源包括至少一个载波,第一参考信号在至少一个载波上传输。
本申请实施例对第一资源配置信息的内容不作限定,可选地,第一参考信号的传输资源包括时域资源,从而,第一资源配置信息包括时域参数;第一参考信号的传输资源包括频域资源,从而,第一资源配置信息包括频域参数;第一参考信号的传输资源包括发射功率,从而,第一资源配置信息包括功率参数。当然,第一参考信号的传输资源也可以包括时域资源、频域资源、发射功率中的任意多项,从而,第一资源配置信息包括与传输资源的多项内容分别对应的参数。例如,第一参考信号的传输资源包括时域资源和频域资源,那么,第一资源配置信息包括时域参数和频域参数。
下面,对时域资源和时域参数进行介绍说明。
在一种可能的实施方式中,至少一个载波上的子载波间隔(Sub-Carrier Space,SCS)相同。
基于此,在一个示例中,第一资源配置信息包括传输资源对应的时域参数,时域参数用于指示至少一个载波上的时域资源。也即,第一参考信号的传输所占用的至少一个载波对应于相同的时域参数。从而,网络设备可以在第一资源配置信息中配置一套时域参数,至少一个载波均对应于这一套时域参数;当然, 网络设备也可以在第一资源配置信息中配置至少一个载波分别对应的时域参数,且至少一个载波分别对应的时域参数均相同。可选地,时域参数包括以下至少一项:周期、起始时隙、起始符号、占用的符号数量。
本实施方式中,针对至少一个载波上的子载波间隔相同的情况,通过统一配置至少一个载波上的时域资源,有助于减少网络设备针对时域资源的配置开销,且减少第一资源配置信息占用的比特数。
在另一种可能的实施方式中,至少一个载波中存在至少两个载波上的子载波间隔不相同。
基于此,在一个示例中,第一资源配置信息包括至少一个载波中参考载波对应的时域参数,该参考载波对应的时域参数用于指示参考载波上的时域资源。可选地,至少一个载波中其它载波上的时域资源,与参考载波上的时域资源相同。也即,网络设备可以在第一资源配置信息中配置一套时域参数,这一套时域参数用于指示参考载波上的时域资源,其它载波上的时域资源基于参考载波上的时域资源确定。可选地,参考载波为至少一个载波中子载波间隔最小的载波;或者,参考载波为至少一个载波中子载波间隔最大的载波。可选地,时域参数包括以下至少一项:周期、起始时隙、起始符号、占用的符号数量。
本示例中,针对存在至少两个载波上的子载波间隔不相同的情况,通过从至少一个载波中选取参考载波并配置该参考载波上的时域资源,其余载波上的时域资源基于该参考载波上的时域资源确定,由于网络设备仅配置参考载波上的时域资源即可同时实现对其余载波上的时域资源的配置,有助于减少网络设备针对时域资源的配置开销,且减少第一资源配置信息占用的比特数。
示例性地,如图3(a)所示,参考载波的子载波间隔为15KHz(千赫兹),基于第一资源配置信息中参考载波对应的时域参数可以确定参考载波上的时域资源占用4个符号。那么,对于子载波间隔为30KHz的载波,由于30KHz大于15KHz,子载波间隔越大则符号持续时间越短,从而子载波间隔为30KHz的载波上的时域资源则占用8个符号,且这8个符号与参考载波上的时域资源所占用的4个符号是相同的时间位置,或者可以说,子载波间隔为30KHz的载波上的时域资源,与参考载波上的时域资源是相同的。
在另一个示例中,第一资源配置信息包括至少一个载波中各个载波分别对应的时域参数,时域参数用于指示对应载波上的时域资源。可选地,时域参数 包括以下至少一项:周期、起始时隙、起始符号、占用的符号数量。在本示例中,两个载波上的子载波间隔不相同时,这两个载波上的时域资源可以不相同,也可以相同,本示例对此不作限定。
本示例中,针对存在至少两个载波上的子载波间隔不相同的情况,通过对至少一个载波中各个载波分别配置时域资源,实现了结合各个载波的特点有区别地、有针对性地配置时域资源,有助于实现精确化、细粒度的资源配置。
以至少一个载波包括第一载波和第二载波,且第一载波上的子载波间隔和第二载波上的子载波间隔不相同为例,可选地,在第一载波上的子载波间隔小于第二载波上的子载波间隔的情况下,第一载波上的时域资源包含第二载波上的时域资源。也即,网络设备针对各个载波分别配置时域参数,该时域参数的配置满足以下条件:子载波间隔较小的载波上的时域资源,包含子载波间隔较大的子载波上的时域资源。
示例性地,如图3(b)所示,15KHz小于30KHz,且子载波间隔为15KHz的载波上的时域资源占用4个符号,那么,子载波间隔为30KHz的载波上的时域资源占用与这4个符号相同时间位置的8个符号中的部分符号,可选地,该部分符号是该8个符号中连续的符号,如该8个符号中连续的4个符号。
以至少一个载波包括第三载波和第四载波,且第三载波上的子载波间隔和第四载波上的子载波间隔不相同为例,可选地,在第三载波上的时域资源与第四载波上的时域资源相同的情况下,第三载波对应的时域参数与第四载波对应的时域参数不相同。也即,网络设备针对各个载波分别配置时域参数,子载波间隔不相同的载波对应的时域参数也不相同,但所指示的时域资源是相同的。
示例性地,如图3(c)所示,15KHz小于30KHz,且子载波间隔为15KHz的载波上的时域资源占用4个符号,那么,子载波间隔为30KHz的载波上的时域资源占用与这4个符号相同时间位置的8个符号中的全部符号。
需要说明的一点是,在至少一个载波中存在至少两个载波上的子载波间隔不相同的情况下,网络设备可以针对至少一个载波中各个载波分别配置时域参数;也可以针对至少一个载波中子载波间隔相同的载波统一配置时域参数、针对至少一个载波中子载波间隔不相同的载波分别配置时域参数。有关子载波间隔相同的载波统一配置时域参数、子载波间隔不相同的载波分别配置时域参数的介绍说明,请参见上述实施例,此处不多赘述。
下面,对频域位置和频域参数进行介绍说明。
在一个示例中,第一资源配置信息包括至少一个载波中各个载波分别对应的频域参数,频域参数用于指示载波上的频域资源。也就是说,网络设备针对至少一个载波中各个载波分别配置频域参数。可选地,频域参数包括起始物理资源块和/或频域梳状值(combsize),频域梳状值用于指示第一参考信号在频域上间隔的资源单元(resource element)数量。本示例中,通过对至少一个载波中各个载波分别配置频域资源,有助于实现精确化、细粒度的资源配置。
在另一个示例中,第一资源配置信息包括至少一个载波中第五载波对应的频域参数,第五载波对应的频域参数用于指示第五载波上的频域资源。可选地,至少一个载波中其它载波对应的频域参数为默认参数,如其它载波对应的起始物理资源块位置默认为0;或者,至少一个载波中其它载波对应的频域参数与第五载波对应的频域参数相同,如其它载波对应的频域梳状值与第五载波对应的频域梳状值相同。也就是说,网络设备仅配置至少一个载波中某一个载波的频域参数,其它载波使用默认的频域参数(默认参数),或者与网络设备所配置的那一个载波的频域参数相同。可选地,默认参数由通信协议预定义或者由网络设备预配置。可选地,频域参数包括起始物理资源块和/或频域梳状值,频域梳状值用于指示第一参考信号在频域上间隔的资源单元数量。本示例中,通过配置一个载波上的频域资源,其余载波上的频域资源与该载波上的频域资源相同或者为默认,由于网络设备仅需配置一个载波上的频域资源,有助于减少网络设备针对频域资源的配置开销,且减少第一资源配置信息占用的比特数。
下面,对发射功率进行介绍说明。
在一个示例中,第一参考信号的发射功率,与至少一个载波之间的间隔呈正相关关系。也就是说,第一参考信号的发射功率基于至少一个载波之间的间隔确定,至少一个载波之间的间隔越大,第一参考信号的发射功率也越大。示例性地,第一参考信号包括PRS,PRS的发射功率与至少一个载波之间的间隔呈正相关关系。本示例中,通过结合载波之间的间隔来确定第一参考信号的发射功率,确保了第一参考信号的发射功率能够支持第一参考信号基于载波聚合的方式传输。
在另一个示例中,第一参考信号的发射功率与第二参考信号的发射功率相同;或者,第一参考信号的发射功率参考第二参考信号的发送功率确定;第二 参考信号包括以下至少一项:SSB(Synchronization Signal Block,同步信号块)、用于计算路径损耗的参考信号。示例性地,第一参考信号包括PRS,PRS的发射功率与SSB的发射功率相同;或者,第一参考信号包括SRS,SRS的发射功率参考用于计算路径损耗的参考信号确定。本示例中,通过参考第二参考信号的发射功率来确定第一参考信号的发射功率,避免了对第一参考信号的发射功率的重复计算,有助于减少计算和处理开销。
综上所述,本申请实施例提供的技术方案,通过基于载波聚合的方式传输用于实现定位的参考信号,提升了定位精度。并且,本申请实施例中,网络设备向终端设备发送资源配置信息,以向终端设备指示用于实现定位的参考信号的传输资源,如时域资源、频域资源、发射功率等等,提供了一种在载波聚合的情况下,配置用于实现定位的参考信号的方法,有助于实现定位精度的提升。
需要说明的一点是,在上述实施例中,以终端设备和网络设备之间交互的角度,对本申请实施例提供的资源配置方法进行了介绍说明。在上述实施例中,有关终端设备所执行的步骤,可以单独实现为终端设备侧的资源配置方法;有关网络设备所执行的步骤,可以单独实现为网络设备侧的资源配置方法。
