技术领域
本申请涉及通信领域中的资源管理技术，尤其涉及一种信号配置方法、装置及存储介质。
背景技术
5G NR将支持低频(小于6GHz频段)+高频(6GHz-100GHz)的全频段接入。高频段的相位噪声问题非常突出，相位噪声是由于本振的非理想性造成的。与小于6GHz的低频段通信系统相比，6GHz-100GHz高频段通信系统由于对参考时钟源的倍频次数大幅增加，其相位噪声也相应大幅增加。相位噪声会恶化收端SNR或EVM，造成大量误码，从而直接限制高阶星座调制的使用，严重影响系统容量。
目前，以一种时域固定连续频域固定密度的方式配置相位跟踪参考信号，这种以固定方式配置的相位跟踪参考信号虽然在相位跟踪性能上优异，但由于时域的连续性以及频域密度的不变性，导致参考信号的开销非常大，频谱效率非常低。
发明内容
本申请的主要目的在于提出一种信号配置方法、装置及存储介质，旨在解决现有技术中存在的上述问题。
为实现上述目的，本申请提供一种信号配置方法，包括：

具体实施方式
下面结合附图和具体实施例对本申请作进一步详细说明。
实施例一、
本申请实施例提供一种信号配置方法，如图1所示，包括：
步骤101：获取至少一种参考信息；所述参考信息用于表征所处通信网络的配置情况；
步骤102：基于所述至少一种参考信息，对所述相位跟踪参考信号的时域和/或频域资源进行配置，得到针对所述相位跟踪参考信号的时域和/或频域资源的配置信息；其中，所述配置信息包括有时域和/或频域资源所对应的密度或图样。
进一步需要说明的是，所述至少一种参考信息，包括以下至少之一：
相位噪声单边带功率谱密度、调制与编码策略MCS、子载波间隔、所需调度的时域和/或频域资源块的数量、通信波形；
其中，所述相位噪声单边带功率谱密度可以通过相位噪声模型获得， 当前可以理解的是，还可以采用其他的方法获得，本实施例中不进行穷举。相位噪声单边带功率谱密度，其形状主要由本振的成本，频段，工艺和功耗有关，这里不进行赘述。
MCS为调制与编码策略，用于对不同的调制和编码方式进行编号，以便系统调用不同的通信策略。比如，在802.11通信中使用MCS index(调制与编码策略索引值)对无线通信进行速率配置，以应对不同的通信环境。
相应的，所述基于所述至少一种参考信息，对所述相位跟踪参考信号的时域和/或频域进行配置，包括以下至少之一：
所述基于所述至少一种参考信息，对所述相位跟踪参考信号的时域和/或频域资源进行配置，包括以下至少之一：
至少基于频偏增加时所对应的所述相位噪声单边带功率谱密度，对所述相位跟踪参考信号的时域和/或频域资源进行配置；
至少基于所述MCS，对所述相位跟踪参考信号的时域和/或频域资源进行配置；
至少基于所述子载波间隔，对所述相位跟踪参考信号的时域和/或频域资源进行配置；
至少基于所述所需调度的时域和/或频域资源块的数量，对所述相位跟踪参考信号的时域和/或频域资源进行配置；
至少基于通信波形，对所述相位跟踪参考信号的时域和/或频域资源进行配置。
具体的：
若随着频偏的增加相位噪声单边带功率谱密度的下降速度增加，则所述相位跟踪参考信号的时域和/或频域资源的密度配置为第一密度阈值范围；若随着频偏的增加相位噪声单边带功率谱密度的下降速度减慢，则所述相位跟踪参考信号的时域和/或频域资源的密度配置为第二密度阈值范 围；其中，所述第一密度阈值范围中的数值均小于第二密度阈值范围中的数值；所述第一密度阈值范围或第二密度阈值范围中，分别包含相互交叉或不交叉的密度阈值子集；
也就是说，相位噪声模型与相位跟踪参考信号时域和频域配置关系：相位噪声单边带功率谱密度随着频偏的增加下降速度越慢，所需相位跟踪参考信号时域和频域密度越高；相位噪声单边带功率谱密度随着频偏的增加下降速度越快，所需相位跟踪参考信号时域和频域密度越低。
需要指出的是，上述第一密度阈值范围以及第二密度阈值范围中，可以以时域连续、频域小于10％所对应的密度作为上限。
当所述MCS处于第一预设范围内时，配置所述相位跟踪参考信号的时域和/或频域资源的密度为第一密度阈值范围内；当所述MCS处于第二预设范围内时，配置所述相位跟踪参考信号的时域和/或频域资源的密度为第二密度阈值范围内；其中，所述第一预设范围中的数值均小于第二预设范围中的数值，所述第一密度阈值范围中的数值均小于第二密度阈值范围中的数值。所述第一预设范围或第二预设范围中，分别包含相互交叉或不交叉的预设子集。
即，MCS与相位跟踪参考信号时域和频域配置关系：低MCS所需相位跟踪参考信号时域和频域密度低；高MCS所需相位跟踪参考信号时域和频域密度高。
进一步地，子载波间隔与相位跟踪参考信号时域和频域配置关系：当所述子载波间隔处于第三预设范围内时，配置所述相位跟踪参考信号的时域和/或频域资源的密度为第一密度阈值范围内；当所述子载波间隔处于第四预设范围内时，配置所述相位跟踪参考信号的时域和/或频域资源的密度为第二密度阈值范围内；其中，所述第三预设范围中的数值均大于第四预设范围中的数值。其中，所述第三预设范围或第四预设范围内可以分别包 括有至少一个预设范围子集，这里不进行赘述。
具体来说，子载波间隔越大，所需相位跟踪参考信号时域和频域密度越低；子载波间隔越小，所需相位跟踪参考信号时域和频域密度越高。可以理解的是，不同的子载波间隔及其对应的时域以及频域密度可以为预先设置好的对应表，该对应表遵循的规律即子载波间隔越大，所需相位跟踪参考信号时域和频域密度越低；子载波间隔越小，所需相位跟踪参考信号时域和频域密度越高；或者，还可以为具备几种级别，当子载波间隔处于第一级范围内时，确定采用第一密度对时域以及频域的密度进行配置，依次类推；其中，每一级范围的数值均不相同。
所述所需调度的时域和/或频域资源块的数量与相位跟踪参考信号时域和频域配置关系：基于所需调度的时域和/或频域资源快的数量，对所述相位跟踪参考信号的时域和/或频域资源配置可分配上限值以及可分配下限值。也就是说，相位跟踪参考信号时域和/或频域配置不用随着所调度RB的增加而相应成比例的增加，而是其时域和/或频域配置个数有某一最大可分配上限值与最小可分配下限值。
当通信波形为单载波时，配置的时域和/或频域资源的密度为第一密度；当通信波形为OFDM时，配置的时域和/或频域资源的密度为第二密度；其中，所述第一密度小于第二密度。基于通信波形，确定所述相位跟踪参考信号的时域和/或频域资源所对应的密度具体可以为，波形与相位跟踪参考信号时域和频域配置关系：采用单载波通信的系统比采用OFDM通信的系统所需相位跟踪参考信号时域和频域密度要低。
在完成相位跟踪参考信号时域和频域的图样配置之后，可以将图样的配置信息可以通过显性或隐性的信令指示方式通知接收端。
首先介绍以显性的信令指示方式通知接收端的处理：
得到针对所述相位跟踪参考信号的时域及频域的图样之后，所述方法 还包括：
通过DCI、RRC、UL授权(grant)中至少之一，将针对所述相位跟踪参考信号的时域及频域的图样发送至接收端；
或者，通过UCI等信息，将针对所述相位跟踪参考信号的时域及频域的图样发送至接收端。
也就是说当基站进行配置，终端进行接收时，通过下行信令进行发送，具体为通过DCI、RRC、UL授权(grant)中至少之一的信令指示方式通知终端；
当终端进行配置、基站接收时，通过上行信令进行发送，具体为通过UCI等信令指示方式通知基站。
接下来针对以隐性的信令指示方式通知接收端的方式进行说明：
通过DCI、RRC、UL授权(grant)中至少之一的，向接收端发送对所述相位跟踪参考信号的时域和/或频域的配置与至少一个参考信息相关的指示信息；
或者，通过UCI等信息，向接收端发送对所述相位跟踪参考信号的时域和/或频域的配置与至少一个参考信息相关的指示信息。
具体的，当基站通知终端相关配置时，下行：通过DCI、RRC、UL授权(grant)中至少之一的信令指示方式通知终端相位跟踪参考信号时域和频域配置与相位噪声模型或/与MCS或/与子载波间隔或/与所调度RB或/与波形有关，终端根据这些信息通过查表等方式得出相位跟踪参考信号时域和频域配置。
当终端通知基站相关配置时，上行：通过UCI等信令指示方式通知基站相位跟踪参考信号时域和频域配置与相位噪声模型或/与MCS或/与子载波间隔或/与所调度RB或/与波形有关，基站根据这些信息通过查表等方式得出相位跟踪参考信号时域和频域配置。
得到针对所述相位跟踪参考信号的时域及频域的图样之后，所述方法还包括：
判断所述时域以及频域的图样所对应的资源位置处，是否配置有至少一种参考信号；其中，所述至少一种参考信号为与所述相位跟踪参考信号不同的其他参考信号；
若配置有至少一种参考信号，则将所述相位跟踪参考信号与所配置的至少一种参考信号进行复用。
其中，所述其余参考信号，包括上行和下行用来估计测量信道或用作同步等功能的已知信号，可以为DMRS,CSI-RS或SRS等。具体的，相位跟踪参考信号可以充分与已经存在的其余参考信号进行复用。复用指的是，如果其余参考信号已经存在相应的时域和频域资源中，就不需要配置所述相位跟踪参考信号了。其它参考信号的作用是估计估计测量信道或用作同步等功能，其具体发射的信息，这里不做赘述。
进一步地，若配置有至少一种参考信号，则判断所述至少一种参考信号是否将针对所述相位跟踪参考信号的时域及频域的图样所对应的资源位置全部占用；
若存在至少一个时域及频域资源位置未占用，则在所述至少一个未占用的时域及频域资源位置处配置所述相位跟踪参考信号。
也就是说，相位跟踪参考信号时域和频域所需数量与相位噪声模型，MCS，子载波间隔，所调度RB以及波形有关，如果当前时域和频域其余参考信号数量不足，则需要根据基于得到的所述相位跟踪参考信号的配置进行相应补充。
可见，通过采用上述方案，就能够基于参考信息对相位跟踪信号进行时域以及频域资源的相关配置，如此，就避免了固定配置相位跟踪信号的方式所带来的信号开销较大的问题，从而提升了相位跟踪参考信号的频谱 效率。

进一步需要说明的是，所述至少一种参考信息，包括以下至少之一：

其中，所述相位噪声单边带功率谱密度可以通过相位噪声模型获得，当前可以理解的是，还可以采用其他的方法获得，本实施例中不进行穷举。相位噪声单边带功率谱密度，其形状主要由本振的成本，频段，工艺和功耗有关，这里不进行赘述。
MCS为调制与编码策略，用于对不同的调制和编码方式进行编号，以便系统调用不同的通信策略。比如，在802.11通信中使用MCS index(调制与编码策略索引值)对无线通信进行速率配置，以应对不同的通信环境。

也就是说，相位噪声模型与相位跟踪参考信号时域和频域配置关系：相位噪声单边带功率谱密度随着频偏的增加下降速度越慢，所需相位跟踪参考信号时域和频域密度越高；相位噪声单边带功率谱密度随着频偏的增加下降速度越快，所需相位跟踪参考信号时域和频域密度越低。
需要指出的是，上述第一密度阈值范围以及第二密度阈值范围中，可以以时域连续、频域小于10％所对应的密度作为上限。
当所述MCS处于第一预设范围内时，配置所述相位跟踪参考信号的时域和/或频域资源的密度为第一密度阈值范围内；当所述MCS处于第二预设范围内时，配置所述相位跟踪参考信号的时域和/或频域资源的密度为第二密度阈值范围内；其中，所述第一预设范围中的数值均小于第二预设范围中的数值，所述第一密度阈值范围中的数值均小于第二密度阈值范围中的数值。所述第一预设范围或第二预设范围中，分别包含相互交叉或不交叉 的预设子集。
即，MCS与相位跟踪参考信号时域和频域配置关系：低MCS所需相位跟踪参考信号时域和频域密度低；高MCS所需相位跟踪参考信号时域和频域密度高。
进一步地，子载波间隔与相位跟踪参考信号时域和频域配置关系：当所述子载波间隔处于第三预设范围内时，配置所述相位跟踪参考信号的时域和/或频域资源的密度为第一密度阈值范围内；当所述子载波间隔处于第四预设范围内时，配置所述相位跟踪参考信号的时域和/或频域资源的密度为第二密度阈值范围内；其中，所述第三预设范围中的数值均大于第四预设范围中的数值。其中，所述第三预设范围或第四预设范围内可以分别包括有至少一个预设范围子集，这里不进行赘述。
所调度RB与相位跟踪参考信号时域和频域配置关系：基于所需调度的时域和/或频域资源快的数量，对所述相位跟踪参考信号的时域和/或频域资源配置可分配上限值以及可分配下限值。也就是说，相位跟踪参考信号时域和/或频域配置不用随着所调度RB的增加而相应成比例的增加，而是其时域和/或频域配置个数有某一最大可分配上限值与最小可分配下限值。
当通信波形为单载波时，配置的时域和/或频域资源的密度为第一密度；当通信波形为OFDM时，配置的时域和/或频域资源的密度为第二密度；其中，所述第一密度小于第二密度。基于通信波形，确定所述相位跟踪参考信号的时域和/或频域资源所对应的密度具体可以为，波形与相位跟踪参考信号时域和频域配置关系：采用单载波通信的系统比采用OFDM通信的系统所需相位跟踪参考信号时域和频域密度要低。
在完成相位跟踪参考信号时域和频域的图样配置之后，可以将图样的配置信息通过显性或隐性的信令指示方式通知接收端。
首先介绍以显性的信令指示方式通知接收端的处理：
在图2-1的基础上，参见图2-2，所述装置还包括：
通信单元23，用于通过DCI或RRC，将针对所述相位跟踪参考信号的时域及频域的图样发送至接收端；
或者，通过UCI等信息，将针对所述相位跟踪参考信号的时域及频域的图样发送至接收端。
也就是说当基站进行配置，终端进行接收时，通过下行信令进行发送，具体为通过DCI、RRC、UL授权(grant)中至少之一的信令指示方式通知终端；
当终端进行配置、基站接收时，通过上行信令进行发送，具体为通过UCI等信令指示方式通知基站。
接下来针对以隐性的信令指示方式通知接收端的方式进行说明：

或者，通过UCI等信息，向接收端发送对所述相位跟踪参考信号的时域和/或频域的配置与至少一个参考信息相关的指示信息。
具体的，当基站通知终端相关配置时，下行：通过DCI、RRC、UL授权(grant)中至少之一的信令指示方式通知终端相位跟踪参考信号时域和频域配置与相位噪声模型或/与MCS或/与子载波间隔或/与所调度RB或/与波形有关，终端根据这些信息通过查表等方式得出相位跟踪参考信号时域和频域配置。

相应的，所述处理器41，执行以下处理至少之一：
至少基于频偏增加时所对应的所述相位噪声单边带功率谱密度，对所述相位跟踪参考信号的时域和/或频域资源进行配置；
至少基于所述MCS，对所述相位跟踪参考信号的时域和/或频域资源进行配置；
至少基于所述子载波间隔，对所述相位跟踪参考信号的时域和/或频域资源进行配置；
至少基于所述所需调度的时域和/或频域资源块的数量，对所述相位跟踪参考信号的时域和/或频域资源进行配置；
至少基于通信波形，对所述相位跟踪参考信号的时域和/或频域资源进 行配置。
具体的：
若随着频偏的增加相位噪声单边带功率谱密度的下降速度增加，则所述相位跟踪参考信号的时域和/或频域资源的密度配置为第一密度阈值范围；若随着频偏的增加相位噪声单边带功率谱密度的下降速度减慢，则所述相位跟踪参考信号的时域和/或频域资源的密度配置为第二密度阈值范围；其中，所述第一密度阈值范围中的数值均小于第二密度阈值范围中的数值；所述第一密度阈值范围或第二密度阈值范围中，分别包含相互交叉或不交叉的密度阈值子集；
也就是说，相位噪声模型与相位跟踪参考信号时域和频域配置关系：相位噪声单边带功率谱密度随着频偏的增加下降速度越慢，所需相位跟踪参考信号时域和频域密度越高；相位噪声单边带功率谱密度随着频偏的增加下降速度越快，所需相位跟踪参考信号时域和频域密度越低。
需要指出的是，上述第一密度阈值范围以及第二密度阈值范围中，可以以时域连续、频域小于10％所对应的密度作为上限。
当所述MCS处于第一预设范围内时，配置所述相位跟踪参考信号的时域和/或频域资源的密度为第一密度阈值范围内；当所述MCS处于第二预设范围内时，配置所述相位跟踪参考信号的时域和/或频域资源的密度为第二密度阈值范围内；其中，所述第一预设范围中的数值均小于第二预设范围中的数值，所述第一密度阈值范围中的数值均小于第二密度阈值范围中的数值。所述第一预设范围或第二预设范围中，分别包含相互交叉或不交叉的预设子集。
即，MCS与相位跟踪参考信号时域和频域配置关系：低MCS所需相位跟踪参考信号时域和频域密度低；高MCS所需相位跟踪参考信号时域和频域密度高。
进一步地，子载波间隔与相位跟踪参考信号时域和频域配置关系：当所述子载波间隔处于第三预设范围内时，配置所述相位跟踪参考信号的时域和/或频域资源的密度为第一密度阈值范围内；当所述子载波间隔处于第四预设范围内时，配置所述相位跟踪参考信号的时域和/或频域资源的密度为第二密度阈值范围内；其中，所述第三预设范围中的数值均大于第四预设范围中的数值。其中，所述第三预设范围或第四预设范围内可以分别包括有至少一个预设范围子集，这里不进行赘述。
所调度RB与相位跟踪参考信号时域和频域配置关系：基于所需调度的时域和/或频域资源快的数量，对所述相位跟踪参考信号的时域和/或频域资源配置可分配上限值以及可分配下限值。也就是说，相位跟踪参考信号时域和/或频域配置不用随着所调度RB的增加而相应成比例的增加，而是其时域和/或频域配置个数有某一最大可分配上限值与最小可分配下限值。
当通信波形为单载波时，配置的时域和/或频域资源的密度为第一密度；当通信波形为OFDM时，配置的时域和/或频域资源的密度为第二密度；其中，所述第一密度小于第二密度。基于通信波形，确定所述相位跟踪参考信号的时域和/或频域资源所对应的密度具体可以为，波形与相位跟踪参考信号时域和频域配置关系：采用单载波通信的系统比采用OFDM通信的系统所需相位跟踪参考信号时域和频域密度要低。
在完成相位跟踪参考信号时域和频域的图样配置之后，可以将图样的配置信息通过显性或隐性的信令指示方式通知接收端。
首先介绍以显性的信令指示方式通知接收端的处理：
所述装置还包括：
通信接口42，用于通过DCI、RRC、UL grant中至少之一，将针对所述相位跟踪参考信号的时域及频域的图样发送至接收端；
或者，通过UCI等信息，将针对所述相位跟踪参考信号的时域及频域的 图样发送至接收端。
也就是说当基站进行配置，终端进行接收时，通过下行信令进行发送，具体为通过DCI、RRC、UL授权(grant)中至少之一信令指示方式通知终端；
当终端进行配置、基站接收时，通过上行信令进行发送，具体为通过UCI等信令指示方式通知基站。
接下来针对以隐性的信令指示方式通知接收端的方式进行说明：
通信接口42，通过DCI、RRC、UL grant中至少之一，向接收端发送对所述相位跟踪参考信号的时域和/或频域的配置与至少一个参考信息相关的指示信息；
或者，通过UCI等信息，向接收端发送对所述相位跟踪参考信号的时域和/或频域的配置与至少一个参考信息相关的指示信息。
具体的，当基站通知终端相关配置时，下行：通过DCI、RRC、UL授权(grant)中至少之一的信令指示方式通知终端相位跟踪参考信号时域和频域配置与
相位噪声模型或/与MCS或/与子载波间隔或/与所调度RB或/与波形有关，终端根据这些信息通过查表等方式得出相位跟踪参考信号时域和频域配置。
当终端通知基站相关配置时，上行：通过UCI等信令指示方式通知基站相位跟踪参考信号时域和频域配置与相位噪声模型或/与MCS或/与子载波间隔或/与所调度RB或/与波形有关，基站根据这些信息通过查表等方式得出相位跟踪参考信号时域和频域配置。
所述处理器41，判断所述时域以及频域的图样所对应的资源位置处，是否配置有至少一种参考信号；其中，所述至少一种参考信号为与所述相位跟踪参考信号不同的其他参考信号；
若配置有至少一种参考信号，则将所述相位跟踪参考信号与所配置的至少一种参考信号进行复用。
其中，所述其余参考信号，包括上行和下行用来估计测量信道或用作同步等功能的已知信号，可以为DMRS,CSI-RS或SRS等。具体的，相位跟踪参考信号可以充分与已经存在的其余参考信号进行复用。
进一步地，所述配置单元，用于若配置有至少一种参考信号，则判断所述至少一种参考信号是否将针对所述相位跟踪参考信号的时域及频域的图样所对应的资源位置全部占用；
若存在至少一个时域及频域资源位置未占用，则在所述至少一个未占用的时域及频域资源位置处配置所述相位跟踪参考信号。
也就是说，相位跟踪参考信号时域和频域所需数量与相位噪声模型，MCS，子载波间隔，所调度RB以及波形有关，如果当前时域和频域其余参考信号数量不足，则需要根据基于得到的所述相位跟踪参考信号的配置进行相应补充。
现有技术中如图3中所示的固定配置相位跟踪参考信号的方式，图中浅色方块对应的时频资源表征相位跟踪参考信号所分配的固定的时域以及频域资源的位置；而通过采用本申请提供的方案，更加灵活的针对相位跟踪参考信号进行配置，从而避免了固定配置相位跟踪信号的方式所带来的信号开销较大的问题，从而提升了相位跟踪参考信号的频谱效率。
