具体实施方式
这里将详细地对示例性实施例进行说明,其示例表示在附图中。下面的描述涉及附图时,除非另有表示,不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本发明相一致的所有实施方式。相反,它们仅是与如所附权利要求书中所详述的、本发明的一些方面相一致的装置和方法的例子。
相关技术中,在LTE(长期演进)的车联网中,控制信道与业务信道频分复用,因此控制信道和业务信道分别确定各自的自动增益因子。但是在5G(第5代移动通信系统)NR(新空口)的车联网中,控制信道与业务信道时分复用,此时如何确定控制信道和业务信道的自动增益因子,以接收控制信道和业务信道的模拟信号,尚无有效的解决方案。
为解决上述问题,本实施例提供了在时分复用系统中确定控制信道和业务信道的自动增益因子的解决方案,并且根据该自动增益因子接收模拟信号。
图1是根据一示例性实施例示出的一种接收模拟信号的方法的流程图,该接收模拟信号的方法用于用户设备中,其中,用户设备可以是移动电话,计算机,数字广播终端,消息收发设备,游戏控制台,平板设备,医疗设备,健身设备,个人数字助理等。如图1所示,该方法包括以下步骤101-104。
在步骤101中,确定一个时隙中控制信道的第一自动增益因子。
在步骤102中,根据所述第一自动增益因子,接收一个时隙中同一用户设备发送的控制信道的第一模拟信号。
在步骤103中,确定一个时隙中业务信道的第二自动增益因子;其中,所述控制信道与所述业务信道时分复用。
在步骤104中,根据所述第二自动增益因子,接收一个时隙中同一用户设备发送的业务信道的第二模拟信号。
本实施例可以由车联网中的用户设备实现,该用户设备可以是车载设备,也可以是路边设备或手持设备等。接收的模拟信号可以来自另外一个用户设备,也可以来自网络侧的基站等设备。
本实施例中用户设备按照原有的自动增益因子接收x微秒(如10-14微秒)的控制信道的第一模拟信号,将x微秒的第一模拟信号输入到用户设备内部的AGC模块,计算出第一自动增益因子,再利用该计算出的第一自动增益因子继续接收控制信道的第一模拟信号。
类似的,用户设备按照原有的自动增益因子接收x微秒(如10-14微秒)的业务信道的第二模拟信号,将x微秒的第二模拟信号输入到用户设备内部的AGC模块,计算出第二自动增益因子,再利用该计算出的第二自动增益因子继续业务控制信道的第二模拟信号。
本实施例中的控制信道和业务信道可以来自于同一用户设备,也可以来自于不同的用户设备。控制信道和业务信道可以位于同一时隙,也可以位于不同时隙。均可以分别确定控制信道和业务信道的第一自动增益因子和第二自动增益因子。
本实施例中的控制信道可以是PSCCH(Physical Sidelink Control Channel,物理直连控制信道),业务信道可以是PSDCH(Physical Sidelink Discovery Channel,物理直连探索信道)。
在一个实施例中,发送控制信道的用户设备与发送业务信道的用户设备是同一用户设备时,第二自动增益因子采用第一自动增益因子。
本实施例中,如果控制信道和业务信道来自同一个用户设备,发送功率不会变化很大,因此可以用相同的自动增益因子来接收第一模拟信号和第二模拟信号,即第二自动增益因子采用第一自动增益因子。这样,可以基本保证接收模拟信号的质量,还可以减少自动增益因子的调整。既可以节省设备功耗,又可以减少自动增益因子的调整对接收模拟信号的影响。
在一个实施例中,发送控制信道的用户设备与发送业务信道的用户设备是同一用户设备时,所述控制信道与所述业务信道位于同一时隙,或者位于不同时隙。
本实施例中,若发送第一模拟信号和发送第二模拟信号的用户设备是同一个用户设备,所述控制信道与所述业务信道位于同一时隙,或者位于不同时隙。控制信道与业务信道是否位于同一时隙,可以由系统规定,也可以由发送端的用户设备调度。
本实施例中,若发送第一模拟信号和发送第二模拟信号的用户设备是同一个用户设备,控制信道与业务信道无论是否属于同一时隙,第二自动增益因子都可以采用第一自动增益因子。由于同一个用户设备的发送功率不会变化很大,因此可以用相同的自动增益因子来接收第一模拟信号和第二模拟信号,即第二自动增益因子采用第一自动增益因子。
在一个实施例中,发送控制信道的用户设备与发送业务信道的用户设备是同一用户设备时,所述方法还包括:步骤A1-步骤A2。
在步骤A1中,判断所述控制信道的时域位置与所述业务信道的时域位置的差值是否小于预设的时长阈值。
在步骤A2中,在所述差值小于预设的时长阈值时,第二自动增益因子采用第一自动增益因子。
在所述差值不小于预设的时长阈值时,第二自动增益因子不采用第一自动增益因子。可根据前述的方法单独确定第二自动增益因子。
本实施例中的时长阈值可以是几个时域符号的长度(如7个时域符号),也可以是几个时隙的长度(如3个时隙)。
判断所述控制信道的时域位置与所述业务信道的时域位置的差值是否小于预设的时长阈值时,控制信道的时域位置可以取控制信道结束的时域位置,业务信道的时域位置可以取业务信道起始的时域位置。或者,控制信道的时域位置可以取控制信道起始的时域位置,此时时长阈值可以配置的略大一些。
如果控制信道的时域位置与所述业务信道的时域位置是固定配置的,那么接收端的用户设备可以预先知道控制信道的时域位置与所述业务信道的时域位置,也就可以预先知道差值。如果控制信道的时域位置与所述业务信道的时域位置不是固定配置的,那么接收端的用户设备在刚接收到业务信道的第二模拟信号时,便可知道控制信道的时域位置与所述业务信道的时域位置,也就可以预先知道差值。在确定第二自动增益因子后,根据第二自动增益因子继续接收业务信道的第二模拟信号。
本实施例利用时长阈值控制控制信道与业务信道的距离,在所述差值小于预设的时长阈值时,确定控制信道与业务信道的距离较小,发送功率不会变化很大,因此第二自动增益因子可以采用第一自动增益因子。在所述差值不小于预设的时长阈值时,确定控制信道与业务信道的距离较大,发送功率可能变化很大,因此第二自动增益因子不宜采用第一自动增益因子。
接收端的用户设备是否要经过步骤A1的判断过程,可以由网络侧进行配置。网络侧可以向用户设备发送RRC(无线资源控制)信令或物理层信令,来通知用户设备是否要经过该判断步骤。
在一个实施例中,所述方法还包括:步骤B。
在步骤B中,判断发送控制信道的用户设备与发送业务信道的用户设备是否是同一用户设备。
本实施例中,如果发送第一模拟信号和发送第二模拟信号的用户设备是同一个用户设备,控制信道与业务信道无论是否属于同一时隙,第二自动增益因子都可以采用第一自动增益因子。因此,需要预先判断发送控制信道的用户设备与发送业务信道的用户设备是否是同一用户设备。如果发送第一模拟信号和发送第二模拟信号的用户设备是同一个用户设备,则第二自动增益因子可以采用第一自动增益因子。如果发送第一模拟信号和发送第二模拟信号的用户设备不是同一个用户设备,则第二自动增益因子可以不采用第一自动增益因子。
在一个实施例中,所述步骤B包括:步骤B1、步骤B2或步骤B3。
在步骤B1中,根据预先配置的同一用户设备发送的控制信道和业务信道的时域位置,确定发送控制信道的用户设备与发送业务信道的用户设备是否是同一用户设备。
本实施例中,预先配置同一用户设备对应的控制信道和业务信道的时域位置,在该时域位置上发送的控制信道和业务信道,就属于同一用户设备。因此,接收端的用户设备通过时域位置便可确定控制信道和业务信道是否属于同一发送端的用户设备。
在步骤B2中,判断控制信道的第一导频符号与业务信道的第二导频符号是否满足预先配置的对应同一用户设备的导频符号。
本实施例中,控制信道和业务信道携带有各自的导频符号,即第一导频符号和第二导频符号。预先配置同一用户设备对应的一组第一导频符号和第二导频符号。接收端的用户设备在接收控制信道和业务信道时,先接收和解析第一导频符号和第二导频符号,判断该第一导频符号和第二导频符号是否满足预先配置的同一用户设备对应的一组第一导频符号和第二导频符号。若满足,则确定控制信道和业务信道属于同一发送端的用户设备。若不满足,则确定控制信道和业务信道不属于同一发送端的用户设备。
同一用户设备对应的一组第一导频符号和第二导频符号,可以相同,也可以不同。
在步骤B3中,解析控制信道,获得控制信道中的控制信息;根据控制信道中的控制信息确定所述控制信道调度的业务信道;其中,所述控制信道与所述控制信道调度的业务信道属于同一用户设备。
本实施例中,接收端的用户设备可以快速的接收和解析控制信道,通过控制信道中的控制信息确定所述控制信道调度的业务信道。该调度的业务信道一定与所述控制信道来自同一用户设备。本实施例适用于硬件处理能力较强的用户设备。因为用户设备需要在接收业务信道之前解析出控制信道中的控制信息。
上述方法中的一种方法,便可确定发送控制信道的用户设备与发送业务信道的用户设备是否是同一用户设备。当然,也可以采用上述多种方法来确定发送控制信道的用户设备与发送业务信道的用户设备是否是同一用户设备。
上述方法中,可以预先配置同一用户设备对应的控制信道和业务信道的时域位置,也可以预先配置对应同一用户设备的导频符号。这些配置信息可以由网络侧的基站等设备发送给用户设备。基站可以向用户设备发送RRC信令或物理层信令等,来发送上述配置信息。
下面通过几个实施例详细介绍实现过程。
