本申请主张在2017年6月23日在中国提交的中国专利申请No.201710488995.4的优先权,其全部内容通过引用包含于此。
本公开涉及通信技术领域,特别涉及一种复合跟踪参考信号的配置、检测方法、基站及终端。
面向未来的第五代(5 Generation,5G)移动通信系统中,为了达到下行链路传输速率20Gbps,上行链路传输速率10Gbps的目标,通信链路的工作频率进一步提高,如厘米波和毫米波等。
一方面,高频段有着更为丰富的频谱资源,可以提供更宽的带宽从而达到更高的传输速率。但是一方面,高频传输也有其特有的问题:更严重的相位噪声、更大的多普勒(Doppler)扩展、更大的频偏等,同时也对通信设备元器件提出了更高的要求。
用户设备在根据主同步信号(Primary Synchronization Signal,PSS)和辅同步信号(Secondary Synchronization Signal,SSS)达到同步之后,还需要对信道进行时频跟踪(Time/Frequency Tracking)。用于时频跟踪的参考信号称为跟踪参考信号(Tracking Reference Signal,TRS)。针对TRS的设计,3GPP RAN1工作组进行了集中讨论。
TRS的功能可以划分为独立的两个方面:
时域跟踪和时延扩展估计:跟踪范围取决于TRS的频域密度,跟踪精度取决于TRS的频域带宽。
频域跟踪和多普勒扩展估计:跟踪范围取决于TRS的时域密度,跟踪精度TRS的时域周期。
而相关技术中的TRS设计方式不能满足时频跟踪性能要求,无法保证通 信可靠性。

为使本公开的目的、技术方案和优点更加清楚,下面将结合附图及具体实施例对本公开进行详细描述。
本公开针对相关技术中的TRS不能满足时频跟踪性能要求,无法保证通信可靠性的问题,提供一种复合跟踪参考信号的配置、检测方法、基站及终端。
如图1所示,本公开实施例提供一种复合跟踪参考信号的配置方法,应用于基站,包括步骤101至103。步骤101,生成目标跟踪参考信号的配置信息。
需要说明的是,该配置信息包括:目标跟踪参考信号的序列参数(该序列参数指的是确定该目标跟踪参考信号符号所需的参数,例如该序列参数包括目标跟踪参考信号的序列长度)、是否配置目标跟踪参考信号的指示信息和目标跟踪参考信号的时频配置参数中的至少一项。
步骤102,根据所述配置信息,在目标参考信号的预设正交频分复用OFDM符号位置不同子载波位置的资源粒子上或相同子载波位置不同OFDM符号位置的资源粒子上增加目标跟踪参考信号,生成复合跟踪参考信号。
需要说明的是,预设OFDM符号位置包括:所述目标参考信号所在的OFDM符号位置或与所述目标参考信号所在的OFDM符号相邻的OFDM符号位置,即在此种情况下,进行目标跟踪参考信号的增加既可以在目标参考信号所在的OFDM符号位置进行增加,也可以在与目标参考信号所在的OFDM符号相邻的OFDM符号上进行增加。
需要说明的是,该目标参考信号指的是现有参考信号;在进行跟踪参考信号的配置时,先获取目标参考信号的信息,然后对该目标参考信号进行相应的时域或频域的扩展,将扩展后的目标参考信号作为基站配置的复合跟踪参考信号。
步骤103,将所述复合跟踪参考信号发送给终端。
基站将该复合跟踪参考信号发送给终端,使得终端按照该配置进行复合跟踪参考信号的检测,以实现时频跟踪。
本实施例的方案,将通过目标参考信号扩展的复合跟踪参考信号发送给终端,以此既降低了新增跟踪参考信号而造成的资源的开销,又保证了新设置的复合跟踪参考信号满足跟踪需求。
需要说明的是,步骤101可以是基站根据网络需求,自行生成目标跟踪参考信号的配置信息,也可以是基站直接获取预设规则中的目标跟踪参考信号的配置信息,该预设规则主要指的是通信标准预配置;当目标跟踪参考信号的配置信息由基站生成时,在步骤101之后,还应包括:通过预设消息将所述配置信息发送给终端;
其中,所述预设消息包括:系统消息(如系统信息块(System Information Block,SIB))、下行控制信息(Downlink Control Information,DCI)和高层信令(如无线资源控制(Radio Resource Control,RRC)信令)中的至少一项。
下面分别从时域和频域角度对生成复合跟踪参考信号的具体方式进行详细说明如下。
一、加大时域跟踪参考信号的带宽
在此种情况下,根据所述配置信息,在目标参考信号的预设正交频分复用OFDM符号位置不同子载波位置的资源粒子上增加目标跟踪参考信号的实现方式为:
根据所述配置信息,在目标参考信号的预设OFDM符号的至少一侧的子载波位置的资源粒子上承载目标跟踪参考信号。
具体地,该目标参考信号包括:辅同步信号(Secondary synchronization signal,SSS)。
还需要说明的是,在此种情况下,当配置信息中包括目标跟踪参考信号 的时频配置参数时,所述时频配置参数为目标跟踪参考信号的带宽信息,该带宽信息具体可以指目标跟踪参考信号所包含子载波的个数。
可选地,当配置信息中包括目标跟踪参考信号的带宽信息时,所述带宽信息的获取方式为:
根据公式:B
A-TRS=f(B
sys)获取目标跟踪参考信号的带宽信息;
其中,B
A-TRS表示目标跟踪参考信号的带宽信息,B
sys表示系统带宽(具体可以指系统信号所包含子载波的个数)。
需要说明的是,当B
A-TRS=0时,表示不存在目标跟踪参考信号。
上述情况一说明的是,当用于时域跟踪的现有参考信号的频域带宽不够宽而导致时域跟踪精度较低时,可以在所述现有参考信号所在OFDM符号的所述现有参考信号的频域一侧或者两侧引入目标跟踪参考信号(即额外跟踪参考信号(Additional TRS,A-TRS))。使得复合跟踪参考信号(由所述现有参考信号和A-TRS组成)的跟踪精度满足要求。
下面在实际应用中,对情况一举例说明如下:
由于SSS的频率密度较高,所以跟踪范围满足要求。但是,由于SSS的带宽有限,所以跟踪精度较差。为此,可以在SSS所在OFDM符号的SSS频域两侧引入A-TRS,如图2所示,其中,实线框表示SSS,虚线框表示A-TRS。其中,A-TRS的配置信息可以通过基站由系统消息、由下行控制信息、高层信令等方式指示给终端;也可以通过标准预置或由系统带宽隐式指示,该隐式指示可以理解为A-TRS的带宽是系统带宽的函数。
情况一中,以SSS为例阐述了加大时域跟踪参考信号带宽的方法,此种方式,使得复合跟踪参考信号的时域跟踪精度达到要求,同时利用了现有的SSS信号,降低了开销。
二、提高时域跟踪参考信号的频域密度
在此种情况下,根据所述配置信息,在目标参考信号的预设正交频分复用OFDM符号位置不同子载波位置的资源粒子上增加目标跟踪参考信号的实现方式为:
根据所述配置信息,判断目标参考信号所在OFDM符号的等间隔预设子载波位置是否可用;
当所述目标参考信号所在OFDM符号的等间隔预设子载波位置可用时,在所述目标参考信号所在OFDM符号的等间隔预设子载波位置的资源粒子上承载目标跟踪参考信号。
还需要说明的是,当所述目标参考信号所在OFDM符号的等间隔预设子载波位置不可用时,在与所述OFDM符号相邻OFDM符号的与预设子载波频域位置相同的子载波位置的资源粒子上承载目标跟踪参考信号。
具体地,该目标参考信号包括:信道状态信息参考信号(Channel State Information Reference Signal,CSI-RS)。
还需要说明的是,在此种情况下,在所述配置信息包括目标跟踪参考信号的时频配置参数时,所述时频配置参数为目标跟踪参考信号的频域密度,需要说明的是,该频域密度指的是目标跟踪参考信号在所述复合跟踪参考信号中所占的比例,且该频域密度可以为绝对密度,也可以为相对于所述现有参考信号的频域密度的相对值。
该情况二说明的是,当用于时域跟踪的现有参考信号的频域密度不够而导致时域跟踪范围较小时,可以在所述现有参考信号所在OFDM符号的等间隔地子载波位置承载A-TRS。使得复合跟踪参考信号(由所述现有参考信号和A-TRS组成)的跟踪范围满足要求。
特别地,当所述现有参考信号所在OFDM符号的相邻子载波之间等间隔的子载波位置由于某种原因不可用,可以在相邻OFDM符号上的对应子载波位置承载A-TRS。
下面在实际应用中,对情况二举例说明如下:
由于CSI-RS的带宽较大,所以时域跟踪精度满足要求。然而,CSI-RS的频域密度通常较低,比如每12个子载波有一个CSI-RS符号(对应于一个CSI-RS端口),所以跟踪范围较小。为此,可以在CSI-RS符号所在符号的相邻子载波之间等间隔地插入一个或者多个A-TRS符号,分别如图3和图4所示,使得复合跟踪参考信号所在子载波在频域上是等间隔的,其中,实线框表示CSI-RS,虚线框表示A-TRS。
其中,A-TRS的配置信息可以通过基站由系统消息、由下行控制信息、高层信令等方式指示给终端;也可以通过标准预置指示。
如图3所示,A-TRS的频域密度为复合跟踪参考信号频域密度的1/2,即复合跟踪参考信号的频域密度为CSI-RS频域密度的2倍;如图4所示,A-TRS的频域密度为复合跟踪参考信号频域密度的2/3,即复合跟踪参考信号的频域密度为CSI-RS频域密度的3倍。
还需要说明的是,当所述CSI-RS所在OFDM符号的相邻子载波之间等间隔的子载波位置由于某种原因不可用,可以在相邻OFDM符号上的对应子载波位置插入一个或者两个A-TRS符号,如图5和图6所示,图5和图6中,均是将A-TRS承载在与CSI-RS所在OFDM符号相邻的右侧的OFDM符号的子载波上,其中,实线框表示CSI-RS,虚线框表示A-TRS。
如图5所示,A-TRS的频域密度为复合跟踪参考信号频域密度的1/2,即复合跟踪参考信号的频域密度为CSI-RS频域密度的2倍;如图6所示,A-TRS的频域密度为复合跟踪参考信号频域密度的2/3,即复合跟踪参考信号的频域密度为CSI-RS频域密度的3倍。
在此情况二中,以CSI-RS为例阐述了提高时域跟踪参考信号频域密度的方法,此种方式,使得复合跟踪参考信号的时域跟踪范围达到要求,同时利用了现有的CSI-RS信号,降低了开销。
需要说明的是,在时域跟踪时,加大跟踪参考信号带宽和提高频域密度的方法(即情况一和情况二)可以结合使用,特别是在所述现有参考信号的带宽和频域密度都不满足条件的情况下(也即带宽较窄且频域密度较低)。
三、提高频域跟踪参考信号的时域密度
在此种情况下,根据所述配置信息,在目标参考信号的相同子载波位置不同OFDM符号位置的资源粒子上增加目标跟踪参考信号的实现方式为:
根据所述配置信息,在目标参考信号所在子载波的OFDM符号之间的OFDM符号位置的资源粒子上承载目标跟踪参考信号。
具体地,所述目标参考信号包括:相位复合跟踪参考信号(Phase Tracking Reference Signal,PTRS)。
还需要说明的是,在此种情况下,当所述配置信息包括目标跟踪参考信号的时频配置参数时,所述时频配置参数为目标跟踪参考信号的时域密度,该时域密度指的是目标跟踪参考信号在所述复合跟踪参考信号中所占的比例, 该时域密度指的是绝对密度或者相对于所述现有参考信号的时域密度的相对值。
该情况三说明的是,当用于频域跟踪的现有参考信号的最小时域间隔不够而导致频域跟踪范围较小时,可以在所述现有参考信号所在子载波的所述现有参考信号所在OFDM符号之间插入A-TRS(可以是等间隔插入,也可以是非等间隔插入)。使得复合跟踪参考信号(由所述现有参考信号和A-TRS组成)的跟踪范围满足要求。
下面在实际应用中,对情况三举例说明如下:
通常,相对于所在时隙(slot),PTRS通常有较长的持续时间,至于其时域密度,虽然可配置,但是其初衷是为了估计相位噪声。在相位噪声比较小的情况下,PTRS的时域密度会比较低。此时,将PTRS用于频域跟踪时,跟踪范围会比较小。为此,可以在PTRS所在子载波的相邻OFDM符号之间插入一个A-TRS。具体实现如图7所示,其中,无填充的实线框表示PTRS,虚线框表示A-TRS。
其中,A-TRS的配置信息可以通过基站由系统消息、由下行控制信息、高层信令等方式指示给终端;也可以通过标准预置指示。
在此情况三中,以PTRS为例阐述了提高频域跟踪参考信号时域密度的方法,此种方式,使得复合跟踪参考信号的频域跟踪范围达到要求,同时利用了现有的PTRS信号,降低了开销。
还需要说明的是,上述用于时域跟踪的参考信号和用于频域跟踪的参考信号,可以结合起来使用。且在实际中,二者通常结合起来使用。
需要说明的是,上述实施例通过在目标参考信号的时频域上增加目标跟踪参考信号,以获取新配置的复合跟踪参考信号,通过此种跟踪参考信号的设置方式,既降低了新增跟踪参考信号而造成的资源的开销,又保证了新设置的复合跟踪参考信号满足跟踪需求,以此保证了5G通信的可靠性和有效性。
如图8所示,本公开实施例还提供一种跟踪参考信号的检测方法,应用于终端,包括:
步骤801,获取目标跟踪参考信号的配置信息;
步骤802,根据所述配置信息,对基站发送的复合跟踪参考信号进行检测;
