Abstract

Description

SRS的传输方法、装置、系统、存储介质及电子装置 技术领域
本公开涉及通信领域，具体而言，涉及一种SRS的传输方法、装置、系统、存储介质及电子装置。
背景技术
在长期演进(Long Term Evolution，简称为LTE)中，物理下行控制信道(Physical Downlink Control Channel，简称为PDCCH)用于承载下行控制信息(Downlink Control Information，简称为DCI)，其中，DCI可包括上、下行调度信息，以及上行功率控制信息。DCI格式(format)分为DCI format 0、1、1A、1B、1C、1D、2、2A、3，3A等，后面演进至LTE-A Release 12(LTE-A版本12)中又增加了DCI format 2B、2C、2D以支持多种不同的应用和传输模式。第一通信节点，例如，演进型基站(e-Node-B，简称为eNB)可以通过下行控制信息配置第二通信节点设备，例如，用户设备(User Equipment，简称为UE)，或者第二通信节点设备接受高层(higher layers)的配置，也称为通过高层信令来配置UE，其中，第一通信节点可以为宏小区的基站、小小区(Small cell)的基站或传输节点、高频通信系统中的发送节点、物联网系统中的发送节点、卫星节点等，第二通信节点可以为UE、手机、便携设备、汽车、卫星节点等通信系统中的节点。
探测参考信号(Sounding Reference Signal，简称为SRS)是一种第二通信节点设备与第一通信节点间用来测量无线信道信息(Channel State Information，简称为CSI)的信号。在长期演进系统中，UE按照eNB指示的频带、频域位置、序列循环移位、周期和子帧偏置等参数，定时在发送子帧的最后一个数据符号上发送上行SRS。eNB根据接收到的SRS判断UE上行的CSI，并根据得到的CSI进行频域选择调度、闭环功率控制等操作。
在LTE-A Release 10(LTE-A版本10)的研究中提出：在上行通信中，应该使用非预编码的SRS，即，天线专有的SRS，而对物理上行共享信道(Physical Uplink Shared Channel，简称为PUSCH)的用于解调的参考信号(De Modulation Reference Signal，简称为DMRS)则进行预编码。第一通信节点通过接收非预编码的SRS，可估计出上行的原始CSI，而经过了预编码的DMRS则不能使第一通信节点估计出上行原始的CSI。此时，当UE使用多天线发送非预编码的SRS时，每个UE所需要的SRS资源都会增加，也就造成了系统内可以同时复用的UE数量下降。UE可通过高层信令(也称为通过trigger type 0触发)或下行控制信息(也称为通过trigger type 1触发)这两种触发方式发送SRS，基于高层信令触发的为周期SRS，基于下行控制信息触发的为非周期SRS。在LTE-A Release 10中增加了非周期发送SRS的方式，一定程度上改善了SRS资源的利用率，提高资源调度的灵活性。
在Rel-15 NR(New Radio Access)的研究中，将SRS的用途分为四种，分别是：波束管理、基于码本、基于非码本、天线切换。
在Rel-17 NR(New Radio Access)的研究中，如何进一步增强SRS的覆盖范围和复用容量，降低对相邻小区的干扰，是一个待解决的问题。
由此可知，相关技术中存在SRS的覆盖范围和复用容量小，对相邻小区造成干扰的问题。
针对相关技术中存在的上述问题，目前尚未提出有效的解决方案。

下文中将参考附图并结合实施例来详细说明本公开。
需要说明的是，本公开的说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。
本申请实施例所提供的方法实施例可以在移动终端、计算机终端或者类似的运算装置中执行。以运行在移动终端上为例，图1是本公开实施例的一种SRS的传输方法的移动终端的硬件结构框图。如图1所示，移动终端可以包括一个或多个(图1中仅示出一个)处理器102(处理器102可 以包括但不限于微处理器MCU或可编程逻辑器件FPGA等的处理装置)和设置为存储数据的存储器104，其中，上述移动终端还可以包括设置为通信功能的传输设备106以及输入输出设备108。本领域普通技术人员可以理解，图1所示的结构仅为示意，其并不对上述移动终端的结构造成限定。例如，移动终端还可包括比图1中所示更多或者更少的组件，或者具有与图1所示不同的配置。

在本实施例中提供了一种SRS的传输方法，图2是根据本公开实施例的SRS的传输方法的流程图一，如图2所示，该流程包括如下步骤：
步骤S202，接收第一通信节点通过信令发送的配置信息，基于所述配置信息向所述第一通信节点发送探测参考信号SRS；或者，根据与第一通信节点约定的规则，向所述第一通信节点发送SRS。
在上述实施例中，发送的探测参考信号SRS可以是部分跳频的SRS (partial frequency hopping SRS transmission)，部分跳频的SRS可以加快基站获得信道信息的速度，还可以在频域上与其他用户的业务错开，降低对其他用户的干扰。除此以外，可以使用重复的部分跳频(partial frequency hopping with repetition)来增强SRS的覆盖，其中，第一通信节点可以为宏小区的基站、小小区(Small cell)的基站或传输节点、高频通信系统中的发送节点、物联网系统中的发送节点、卫星节点等。
其中，上述步骤的执行主体可以为第二通信节点，例如，可以用户设备UE，包括但不限于手机、便携设备等，还可以是车载终端、卫星节点等通信系统中的节点。
通过本公开，基于通过信令发送的配置信息发送探测参考信息SRS，或者，基于约定的规则发送SRS，可以增强SRS的覆盖范围和复用容量，因此，可以解决相关技术中存在的SRS的覆盖范围和复用容量小，对相邻小区造成干扰的问题，达到增强SRS的覆盖范围和复用容量，降低对相邻小区的干扰的效果。
在一个示例性的实施例中，所述信令包括以下至少之一：用于指示周期SRS或半持续SRS在时域上或时隙之间重复发送次数的信息；用于指示SRS资源集在时域上或时隙之间重复发送次数的信息；用于指示非周期SRS不探测全跳转带宽的信息；用于指示在与上一时域发送单元频域位置相同的频域位置上发送SRS的信息；用于指示在与下一时域发送单元频域位置相同的频域位置上发送SRS的信息；用于指示SRS的发送梳在SRS资源之间跳转或随机化的信息。在本实施例中，在发送的探测参考信号SRS是部分跳频的SRS，且信令指示周期SRS或半持续SRS在时域上或时隙之间重复发送次数的信息为2次的情况下，重复利用多个子带中的各子带发送SRS的示意图可参见附图3，如图3所示，图3中a区域用于展示在频域子带1至子带4进行跳频，增强为图3中b区域展示的在子带1重复发送2次、在子带3重复发送2次，n SRS(SRS的传输数量)则以0、0、1、1，...的规律进行累加计数。
在一个示例性的实施例中，所述与第一通信节点约定的规则，包括以下至少之一：周期SRS或半持续SRS在时域上或时隙之间重复发送的次数为跳转带宽与多次发送带宽的比值，其中，所述多次发送带宽为发送带宽与频域不同发送位置数量的乘积；当SRS的频域位置位于不可发送SRS的频域位置时，或者当SRS的频域位置与其他信号的频域完全重叠或部分重叠时，将当前时域位置上的SRS频域位置更新为上一个发送SRS的时域位置对应的频域位置；当SRS的频域位置位于不可发送SRS的频域位置时，或者当SRS的频域位置与其他信号的频域完全重叠或部分重叠时，将当前时域位置上的SRS频域位置更新为下一个发送SRS的时域位置对应的频域位置；当SRS的频域位置位于不可发送SRS的频域位置时，或者当SRS的频域位置与其他信号的频域完全重叠或部分重叠时，SRS的传输数量不进行累加；当SRS的频域位置位于不可发送SRS的频域位置时，或者当SRS的频域位置与其他信号的频域完全重叠或部分重叠时，SRS的传输数量+N，其中，N为大于或等于2且小于或等于10的整数；在SRS为非周期SRS的情况下，SRS传输数量的计算方式为：

其中，l′为SRS资源内的正交频分复用OFDM符号编号，R为第一通信节点通过高层参数配置的重复因子，R partial为第一通信节点通过高层参数配置的用于指示SRS资源或SRS资源集之间重复的因子；在SRS为周期SRS或半持续SRS的情况下，SRS传输数量的计算方式为：

为子载波间隔配置为μ的帧内时隙编号，T SRS为SRS的时隙周期，T offset为SRS的时隙偏置；SRS的 发送梳偏置基于以下参数至少之一得到：符号或时隙索引、频域子带或频带的索引、小区标识ID或UE标识ID、SRS的传输数量n SRS。在本实施例中，当SRS的频域位置位于不可发送SRS的频域位置时，例如，当前时域位置被占用时，可以将当前时域位置上的SRS频域位置更新为上一个发送SRS的时域位置对应的频域位置，或者，将当前时域位置上的SRS频域位置更新为下一个发送SRS的时域位置对应的频域位置，避免了干扰相邻小区。其中，将当前时域位置上的SRS频域位置更新为上一个发送SRS的时域位置对应的频域位置的示意图可参见附图4，如图4所示，其中，图4中的a区域用于展示常规的UE在子带1-4上发送SRS，图4中的b区域用于展示本公开实施例中的UE不在子带3发送SRS，而是在子带1上重复发送SRS，在该情况下，SRS的传输数量则以0、0、2、3,...的规律进行累加计数。将当前时域位置上的SRS频域位置更新为下一个发送SRS的时域位置对应的频域位置的示意图可参见附图5，如图5所示，其中，图5中的a区域用于展示常规的UE在子带1-4上发送SRS，图5中的b区域用于展示本公开实施例中的UE不在子带3发送SRS，而是在子带2上重复发送SRS，在该情况下，SRS的传输数量则以0、2、2、3，...的规律进行累加计数。
在本实施例中，在SRS为非周期SRS的情况下，可以通过引入aperiodic SRS resource(非周期性SRS配置)内的partial frequency hopping(部分跳频)，增强SRS的覆盖，假定slot(时隙)内的所有symbol(符号)都可用于SRS发送，支持每个SRS resource(SRS配置)包含8个symbol，重复因子R＝2。如果通过配置R＝4，则根据现有的标准协议，需要占用所述频域，则要在resource内hopping完成RRC配置的hopping带宽，只能实现如图6中的b区域所示的跳频图样，在引入aperiodic SRS resource内的partial frequency hopping后，只需部分子带发送SRS，可以实现如图7中的b区域所示的跳频图样，比对图7中b区域和图6中的b区域可知，图7中的b区域的频域带宽是图7中的b区域的频域带宽的一半，当发送功率相同时，频域带宽越小，发送能量会越大，覆盖范围也会 越大。
在一个实施例中，所述SRS的发送梳偏置可以基于SRS的传输数量n SRS得到，包括：第p i天线端口上发送的SRS的发送梳偏置

为SRS的天线端口数量。在本实施例中，对于Rel-17SRS增强，随着SRS的发送梳(Transmission comb)数量的增加，SRS的发送功率也会进一步增大，如果小区间没有SRS相关信息的协作，则会带来很大的小区间干扰。因此，可以考虑SRS的comb offset(梳偏移)随着aperiodic SRS resource内做frequency hopping而发生改变，以此达到干扰随机化的目的。即由于梳偏移发生变化时，用于发射SRS的载波也会随之发生变化，因此，可以先确定与发送方式关联的发送梳偏移，基于梳偏移确定用于发送SRS的载波，在载波上发送SRS。其中，可以将comb offset与symbol(符号)/slot index(时隙参数)或频域子带或频带的index(索引)、小区ID(Identity Document)或UE ID进行关联随机化。
在本实施例中提供了一种SRS的传输方法，图8是根据本公开实施例的SRS的传输方法的流程图二，如图8所示，该流程包括如下步骤：
步骤S802，通过信令向第二通信节点发送配置信息，接收所述第二通信节点基于所述配置信息发送的探测参考信号SRS；或者，根据与第二通信节点约定的规则，接收所述第二通信节点发送的SRS。
在上述实施例中，发送的探测参考信号SRS可以是部分跳频的SRS，部分跳频的SRS可以加快基站获得信道信息的速度，还可以在频域与其他用户的业务错开，降低对其他用户的干扰。除此以外，可以使用重复的部分跳频来增强SRS的覆盖。
其中，上述步骤的执行主体可以为第一通信节点，其中，第一通信节点可以为宏小区的基站、小小区(Small cell)的基站或传输节点、高频通信系统中的发送节点、物联网系统中的发送节点、卫星节点等。上述的第二通信节点可以为UE，包括但不限于手机、便携设备等，还可以是车载终端、卫星节点等通信系统中的节点。
通过本公开，基于通过信令发送的配置信息发送探测参考信息SRS，或者，基于约定的规则发送SRS，可以增强SRS的覆盖范围和复用容量，因此，可以解决相关技术中存在的SRS的覆盖范围和复用容量小，对相邻小区造成干扰的问题，达到增强SRS的覆盖范围和复用容量，降低对相邻小区的干扰的效果。
在一个实施例中，所述信令包括以下至少之一：用于指示周期SRS或半持续SRS在时域上或时隙之间重复发送次数的信息；用于指示SRS资源集在时域上或时隙之间重复发送次数的信息；用于指示非周期SRS不探测全跳转带宽的信息；用于指示在与上一时域发送单元频域位置相同的频域位置上发送SRS的信息；用于指示在与下一时域发送单元频域位置相同的频域位置上发送SRS的信息；用于指示SRS的发送梳在SRS资源之间跳转或随机化的信息。在本实施例中，在发送的探测参考信号SRS是部分跳频的SRS，且信令指示周期SRS或半持续SRS在时域上或时隙之间重复发送次数的信息为2次的情况下，重复利用多个子带中的各子带发送SRS的示意图可参见附图3，如图3所示，图3中a区域用于展示在频域子带1至子带4进行跳频，增强为图3中b区域展示的在子带1重复发送2次、在子带3重复发送2次，n SRS(SRS的传输数量)则以0、0、1、1，...的规律进行累加计数。
在一个实施例中，所述与第二通信节点约定的规则，包括以下至少之一：周期SRS或半持续SRS在时域上或时隙之间重复发送的次数为跳转带宽与多次发送带宽的比值，其中，所述多次发送带宽为发送带宽与频域不同发送位置数量的乘积；当SRS的频域位置位于不可发送SRS的频域位置时，或者当SRS的频域位置与其他信号的频域完全重叠或部分重叠时， 将当前时域位置上的SRS频域位置更新为上一个发送SRS的时域位置对应的频域位置；当SRS的频域位置位于不可发送SRS的频域位置时，或者当SRS的频域位置与其他信号的频域完全重叠或部分重叠时，将当前时域位置上的SRS频域位置更新为下一个发送SRS的时域位置对应的频域位置；当SRS的频域位置位于不可发送SRS的频域位置时，或者当SRS的频域位置与其他信号的频域完全重叠或部分重叠时，SRS的传输数量不进行累加；当SRS的频域位置位于不可发送SRS的频域位置时，或者当SRS的频域位置与其他信号的频域完全重叠或部分重叠时，SRS的传输数量+N，其中，N为大于或等于2且小于或等于10的整数；

为子载波间隔配置为μ的每帧时隙数量，n f为系统帧编号，
Figure PCTCN2021085727-appb-000016
为子载波间隔配置为μ的帧内时隙编号，T SRS为SRS的时隙周期，T offset为SRS的时隙偏置；SRS的发送梳偏置基于以下参数至少之一得到：符号或时隙索引、频域子带或频带的索引、小区标识ID或UE标识ID、SRS的传输数量n SRS。在本实施例中，当SRS的频域位置位于不可发送SRS的频域位置时，例如，当前时域位置被占用时，可以将当前时域位置上的SRS频域位置更新为上一 个发送SRS的时域位置对应的频域位置，或者，将当前时域位置上的SRS频域位置更新为下一个发送SRS的时域位置对应的频域位置，避免了干扰相邻小区。其中，将当前时域位置上的SRS频域位置更新为上一个发送SRS的时域位置对应的频域位置的示意图可参见附图4，如图4所示，其中，图4中的a区域用于展示常规的UE在子带1-4上发送SRS，图4中的b区域用于展示本公开实施例中的UE不在子带3发送SRS，而是在子带1上重复发送SRS，在该情况下，SRS的传输数量则以0、0、2、3,...的规律进行累加计数；将当前时域位置上的SRS频域位置更新为下一个发送SRS的时域位置对应的频域位置的示意图可参见附图5，如图5所示，其中，图5中的a区域用于展示常规的UE在子带1-4上发送SRS，图5中的b区域用于展示本公开实施例中的UE不在子带3发送SRS，而是在子带2上重复发送SRS，在该情况下，SRS的传输数量则以0、2、2、3，...的规律进行累加计数。
在本实施例中，在SRS为非周期SRS的情况下，可以通过引入aperiodic SRS resource(非周期性SRS配置)内的partial frequency hopping(部分跳频)，增强SRS的覆盖，假定slot(时隙)内的所有symbol(符号)都可用于SRS发送，支持每个SRS resource(SRS配置)包含8个symbol，重复因子R＝2。如果通过配置R＝4，则根据现有的标准协议，需要占用所述频域，则要在resource内hopping完成RRC配置的hopping带宽，只能实现如图6中的b区域所示的跳频图样，在引入aperiodic SRS resource内的partial frequency hopping后，只需部分子带发送SRS，可以实现如图7中的b区域所示的跳频图样，比对图7中b区域和图6中的b区域可知，图7中的b区域的频域带宽是图7中的b区域的频域带宽的一半，当发送功率相同时，频域带宽越小，发送能量会越大，覆盖范围也会越大。
在一个示例性的实施例中，所述SRS的发送梳偏置可以基于SRS的传输数量n SRS得到，包括：第p i天线端口上发送的SRS的发送梳偏置

为SRS序列循环移位的最大数量，
Figure PCTCN2021085727-appb-000022
为SRS的天线端口数量。在本实施例中，对于Rel-17SRS增强，随着SRS的发送梳(Transmission comb)数量的增加，SRS的发送功率也会进一步增大，如果小区间没有SRS相关信息的协作，则会带来很大的小区间干扰。因此，可以考虑SRS的comb offset(梳偏移)随着aperiodic SRS resource内做frequency hopping而发生改变，以此达到干扰随机化的目的。即由于梳偏移发生变化时，用于发射SRS的载波也会随之发生变化，因此，可以先确定与发送方式关联的发送梳偏移，基于梳偏移确定用于发送SRS的载波，在载波上发送SRS。其中，可以将comb offset与symbol(符号)/slot index(时隙参数)或频域子带或频带的index(索引)、小区ID(Identity Document)或UE ID进行关联随机化。
在前述实施例中，计算SRS在频域跳转时的SRS发送数量，通过减小发送SRS带宽来在某一频带重复发送SRS，以此增强SRS的覆盖范围和复用容量，降低对相邻小区的干扰；当SRS遇到不发送的频域子带，则SRS在此时域位置上重复发送前面的频域子带，或重复发送后面的频域子带，解决了SRS频域跳频与其他用户或其他业务的数据互相冲突的问题。
通过以上的实施方式的描述，本领域的技术人员可以清楚地了解到根据上述实施例的方法可借助软件加必需的通用硬件平台的方式来实现，当然也可以通过硬件，但很多情况下前者是更佳的实施方式。基于这样的理解，本公开的技术方案本质上或者说对现有技术做出贡献的部分可以以软件产品的形式体现出来，该计算机软件产品存储在一个存储介质(如ROM/RAM、磁碟、光盘)中，包括若干指令用以使得一台终端设备(可以是手机，计算机，服务器，或者网络设备等)执行本公开各个实施例所述的方法。
