Description

符号类型的确定方法及装置、存储介质和电子装置 技术领域
本发明涉及通信领域，具体而言，涉及一种符号类型的确定方法及装置、存储介质和电子装置。
背景技术
无线覆盖拉远设备，例如直放站、数字拉远、数字光分布等非基站类的无线覆盖拉远设备。这类设备的主要特点就是一般无法直接获取到基站下发的信令信息。针对时分双工(Time Division Duplex，简称TDD)系统，无法获取上下行配置的信息，进而无法控制远端设备的功放和低噪放的开关。
5G时代的到来，由于频段带宽更大，大多数的频带都是采用TDD的方式，也就是下行信号和上行信号都是处于同一个频率。
针对相关技术中，无线覆盖拉远设备无法获取上下行配置的信息的问题，目前尚未存在有效的解决方案。

可选地，所述根据功率值确定N个目标符号中每个目标符号的符号类型，包括：确定在预设时间范围内功率值大于或等于预设门限值的目标符号为下行符号；确定在预设时间范围内功率值小于所述预设门限值的目标符号为上行符号。
可选地，在所述按照预设时间长度将目标无线帧划分成N个目标符号之前，所述方法包括：根据预先设定的子载波间隔和循环前缀类型确定所述预设时间长度。
可选地，在所述按照预设时间长度将目标无线帧划分成N个目标符号之前，所述方法还包括：接收帧同步指示信息，其中，所述帧同步指示用于指示所述目标无线帧的起始位置；根据所述帧同步指示信息确定所述目标无线帧的所述起始位置。
可选地，在所述根据功率值确定N个目标符号中每个目标符号的符号类型之后，所述方法还包括：在确定所述目标符号为所述下行符号的情况下，开启下行功放开关，并关闭上行低噪放开关；在确定所述目标符号为所述上行符号的情况下，开启所述上行低噪放开关，并关闭所述下行功放开关。
根据本发明的又一个实施例，还提供了一种存储介质，所述存储介质中存储有计算机程序，其中，所述计算机程序被设置为运行时执行上述任一项方法实施例中的步骤。
根据本发明的又一个实施例，还提供了一种电子装置，包括存储器和处理器，所述存储器中存储有计算机程序，所述处理器被设置为运行所述计算机程序以执行上述任一项方法实施例中的步骤。
通过本发明，由于按照预设时间长度将目标无线帧划分成N个目标符号，其中，N为大于0的整数；根据功率值确定N个目标符号中每个目标符号的符号类型。因此，可以解决无线覆盖拉远设备无法获取上下行配置的信息的问题，达到不用通过其他硬件设备无线覆盖拉远设备就可以获取到上下行配置的信息，降低了设备的硬件设计难度，节约硬件成本的效果。

具体实施方式
下文中将参考附图并结合实施例来详细说明本发明。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。
需要说明的是，本发明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。
本申请实施例一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是本发明实施例的一种符号类型的确定方法的移动终端的硬件结构框图。如图1所示，移动终端10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，可选地，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10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。
存储器104可设置为存储计算机程序，例如，应用软件的软件程序以及模块，如本发明实施例中的符号类型的确定方法对应的计算机程序，处理器102通过运行存储在存储器104内的计算机程序，从而执行各种功能应用以及数据处理，即实现上述的方法。存储器104可包括高速随机存储器，还可包括非易失性存储器，如一个或者多个磁性存储装置、闪存、或 者其他非易失性固态存储器。在一些实例中，存储器104可进一步包括相对于处理器102远程设置的存储器，这些远程存储器可以通过网络连接至移动终端10。上述网络的实例包括但不限于互联网、企业内部网、局域网、移动通信网及其组合。
传输装置106设置为经由一个网络接收或者发送数据。上述的网络具体实例可包括移动终端10的通信供应商提供的无线网络。在一个实例中，传输装置106可以为射频(Radio Frequency，简称为RF)模块，其设置为通过无线方式与互联网进行通讯。
在本实施例中提供了一种运行于上述移动终端的符号类型的确定方法，可应用于但不限于5G/NR-TDD直放站、数字光分布系统iDAS、数字拉远系统等类似无线信号覆盖装置或设备。图2是根据本发明实施例的符号类型的确定的流程图，如图2所示，该流程包括如下步骤：
步骤S202，按照预设时间长度将目标无线帧划分成N个目标符号，其中，N为大于0的整数；
其中，预设时间长度可以在设备上电后，由其他功能模块或通过上位机对参数SCS-Subcarrier spacing(子载波间隔)、CP类型进行设定，以确定每个符号的时间长度，每个符号的时间长度对应于预设时间长度。目标无线帧可以任意时长的无线帧，例如可以是10ms无线帧，具体的无线帧时长可以根据实际情况而定。假设目标无线帧为10ms无线帧，那么进行划分后得到的每个目标符号的时间为T＝10ms/N。
步骤S204，根据功率值确定N个目标符号中每个目标符号的符号类型。
其中，符号类型包括：上行符号和下行符号。
通过上述步骤，由于按照预设时间长度将目标无线帧划分成N个目标符号，其中，N为大于0的整数；根据功率值确定N个目标符号中每个目标符号的符号类型。因此，可以解决无线覆盖拉远设备无法获取上下行配置的信息的问题，达到不用通过其他硬件设备无线覆盖拉远设备就可以获 取到上下行配置的信息，降低了设备的硬件设计难度，节约硬件成本的效果。
可选地，上述步骤的执行主体可以为终端等，但不限于此。
作为一个可选的实施例，所述根据功率值确定N个目标符号中每个目标符号的符号类型，包括：确定在预设时间范围内功率值大于或等于预设门限值的目标符号为下行符号；确定在预设时间范围内功率值小于所述预设门限值的目标符号为上行符号。在本实施例中，接受下行同向或正交信号，in-phase同向，quadrature正交，简称I/Q信号。并对N个目标符号中的每个目标符号的功率进行单独统计。设置预设门限的门限值，预设门限值的大小可以根据实际情况而定，例如，当接受到的信号范围最大0dBm，最小-25dBm，那么门限可以设置为-25dBm。当N个目标符号中某个目标符号功率在预设的时间范围T内大于或等于门限值时，便确定该目标符号为下行符号。如果某目标符号功率在预设时间范围T内低于门限值，则认为该符号为上行符号。预设时间范围可以根据实际情况而定，例如1ms，2ms等，以此就完成了10ms无线帧的上下行的配比情况。
作为一个可选的实施例，在所述按照预设时间长度将目标无线帧划分成N个目标符号之前，所述方法包括：根据预先设定的子载波间隔和循环前缀类型确定所述预设时间长度。在本实施例中，可以由其他功能模块或通过上位机对参数子载波间隔(SCS-Subcarrier spacing)、循环前缀(Cyclic Prefix，简称CP)类型类型进行设定，以确定每个符号的时间长度。每个符号的时间长度对应于预设时间长度。
作为一个可选的实施例，在所述按照预设时间长度将目标无线帧划分成N个目标符号之前，所述方法还包括：接收帧同步指示信息，其中，所述帧同步指示用于指示所述目标无线帧的起始位置；根据所述帧同步指示信息确定所述目标无线帧的所述起始位置。在本实施例中，同步模块提供帧同步指示信号，指示10ms无线帧的起始位置。
作为一个可选的实施例，在所述根据功率值确定N个目标符号中每个 目标符号的符号类型之后，所述方法还包括：在确定所述目标符号为所述下行符号的情况下，开启下行功放开关，并关闭上行低噪放开关；在确定所述目标符号为所述上行符号的情况下，开启所述上行低噪放开关，并关闭所述下行功放开关。在本实施例中，可以通过对目标无线帧的上下行的配比情况可以准确的控制下行功放和上行低噪放的周期性的开关，如图3所示，若确定目标符号为下行符号的情况下，开启下行功放开关，并关闭上行低噪放开关，若确定目标符号为上行符号的情况下，启所述上行低噪放开关，并关闭所述下行功放开关。在图3中目标信号可以是5G信号，也可以是新空口(New Radio，简称NR)NR信号。本申请方法简单有效，对于非基站类设备，可以不用采用SIM卡和解调模块等硬件来实现该功能，降低了设备的硬件设计难度和硬件成本。
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，本发明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)执行本发明各个实施例所述的方法。
在本实施例中还提供了一种符号类型的确定装置，该装置用于实现上述实施例及优选实施方式，已经进行过说明的不再赘述。如以下所使用的，术语“模块”可以实现预定功能的软件和/或硬件的组合。尽管以下实施例所描述的装置较佳地以软件来实现，但是硬件，或者软件和硬件的组合的实现也是可能并被构想的。

作为一个可选的实施例，所述第一确定模块包括：第一确定单元，设置为确定在预设时间范围内功率值大于或等于预设门限值的目标符号为下行符号；第二确定单元，设置为确定在预设时间范围内功率值小于所述预设门限值的目标符号为上行符号。
作为一个可选的实施例，所述装置还包括：接收模块，设置为在所述按照预设时间长度将目标无线帧划分成N个目标符号之前，接收帧同步指示信息，其中，所述帧同步指示用于指示所述目标无线帧的起始位置；第二确定模块，设置为根据所述帧同步指示信息确定所述目标无线帧的所述起始位置。
