Description
本申请要求于2021年8月12日提交中国专利局、申请号为“202110925422.X”、申请名称为“一种信号处理方法及相关装置”的中国专利申请的优先权,其全部内容通过引用结合在本申请中。
本申请实施例涉及通信领域,尤其涉及一种信号处理方法及相关装置。
在通信***中,通过波束赋形(beamforming,BF)能够将发射能量集中在特定方向上,可以使得某个方向的发射功率增大而其他方向上的发射功率接近于零,从而达到扩展期望方向的通信距离和避免对其它方向造成干扰的目的。波束赋形包括数字波束赋形(digital beamforming,DBF)、模拟波束赋形(analog beamforming,ABF)和混合波束赋形(hybrid digital and analog beamforming,HBF)。
在HBF架构下,由于公共信道和业务信道受到相同移相器控制,当业务信道调整天线权值以改变波束方向时,公共信道的波束方向也会随之改变,而为了保障业务信道性能最优,需要频繁调整天线权值,而频繁调整天线权值造成了公共信道的发送波束频繁变化产生波动,公共信道主要用于终端设备进行小区测量和信道估计,波束需要保持稳定。
现有技术为了使公共信道的发送波束保持稳定,基站将公共信道的信号只发送到移相器相位固定的一组天线阵列对应的射频通道,即公共信道只使用了小区的一部分射频通道,虽然公共信道的信号发送波束保持稳定,但公共信道总的发送功率只是一部分射频通道的功率之和,导致公共信道的信号发送功率和覆盖范围变小。
发明内容
本申请实施例提供了一种信号处理方法及相关装置,用于提升信号的发送功率和波束的覆盖范围。
本申请实施例第一方面提供了一种信号处理方法,该方法由基站执行,也可以由基站的部件,例如基站的处理器、芯片、或芯片***等执行,还可以由能实现全部或部分服务器功能的逻辑模块或软件实现。第一方面提供的方法包括:接收来自射频通道的第一信号,该第一信号由信号源通过射频通道发送,射频通道通过基带模块和功率电桥分别与第一移相器和第二移相器连接,第一移相器为相位动态调整的移相器,第二移相器为固定相位的移相器,第一信号的目的天线阵列为第一移相器对应的天线阵列,即第一信号原本是第一移相器的信号,基站将功率电桥处理后的第一信号发送至第二移相器。
本申请实施例中基站引入功率电桥,通过设计功率电桥的电桥参数和不同信道的基带权值,使不同信道信号经过基带权值加权并经过功率电桥后发送到指定的移相器,即可以将原本发送相位动态调整的移相器的信号汇聚到相位固定的移相器所在射频通道,在减少 信号波动的同时提升了信号发送功率不下降,波束的覆盖范围不收缩。
基于第一方面,一种的可能的实施方式中,基站接收来自射频通道的第二信号,第二信道的目的天线阵列为第二移相器对应的天线阵列,通过功率电桥处理第一信号和第二信号。第一信号和第二信号可以是基站同时接收的不同射频通道的信号。
本申请实施例中基站将原本发往相位动态调整的移相器的第一信号经过功率电桥发送至相位固定的移相器,相比只向相位固定的移相器发送第二信号,而不向相位动态调整的移相器发送第一信号的方案相比,增加了天线阵列的发送功率,提升了波束的覆盖范围。
基于第一方面,一种的可能的实施方式中,通过功率电桥处理第一信号和第二信号包括通过功率电桥将第一信号叠加至第二信号。

基于第一方面,一种的可能的实施方式中,射频通道包括公共信道和业务信道。第一信号可以是公共信道的射频信号,也可以是业务信道射频信号,公共信道和业务信道的基带权值可以相同或不同。
对于公共信道,公共信道在基带中映射到全部射频通道并使用对应的公共信道基带权值加权发送,对于原本与移相器相位固定的天线阵列相连的射频通道,其发送的第二信号通过功率电桥后,仍然发送到对应的移相器相位固定的天线阵列。对于原本与移相器相位可动态调整的天线阵列相连的射频通道,其发送的第一信号通过功率电桥后,汇聚到移相器相位固定的天线阵列与第二信号叠加发送,即移相器相位固定的天线阵列接收到的公共信道的信号功率提升一倍,而移相器相位可动态调整的天线阵列不发送公共信道的信号。
对于业务信道,业务信道在基带中映射到全部射频通道并使用对应的业务信道基带权值加权发送,经过功率电桥后到达移相器相位固定对应天线阵列的第二信号,和经过功率电桥后到达移相器相位可动态调整的对应天线阵列的第一信号,与未使用功率电桥及相应的基带权值加权时到达对应天线阵列的业务信道信号一致。
本申请实施例中基站可以公共信道的信号和业务信道的信号的传输需求进行电桥参数和基带权值得设计,提升方案的适用性。

请参阅图3,图3为本申请实施例提供的一种基站***示意图。在图3所示的一个示例中,基站接收信号源通过射频通道发送的第一信号,第一信号的目的天线阵列为相位动态调整的移相器所对应的天线阵列,基站通过将经过功率电桥处理的第一信号发送至相位固定的移相器。具体的,基站通过设计基带权值和电桥参数,将经过功率电桥的第一信号的功率汇聚到相位固定的移相器所在的射频通道,并使得第一信号在相位动态调整的移相器的射频通道的功率为零。第一信号可以是公共信道的射频信号,也可以是业务信道射频信号,公共信道和业务信道的基带权值可以相同或不同,例如,图3中公共信道的基带权值为W

请参阅图3,图3为本申请实施例提供的一种基站***示意图。在图3所示的一个示例中,基站接收信号源通过射频通道发送的信号,该信号经过基带模块和功率电桥分别发 往不同的移相器所对应的天线阵列,该信号包括第一信号和第二信号,其中第一信号的目的天线阵列为相位动态调整的移相器所对应的天线阵列,第二信号的目的天线阵列为相位固定的移相器所对应的天线阵列。

下面结合图4介绍本申请实施例所提供的信号处理方法,请参阅图4,图4为本申请实施例提供的一种信号处理方法的功率变化示意图。在图4所示的一个示例中,基站将功率电桥处理后的第一信号发送至第二移相器,使得第一信号与第二信号功率叠加。
如图4所示,射频通道TX0至射频通道TXn上的信号功率为x,其中射频通道TX0和射频通道TXn所连接的移相器为相位固定的移相器,射频通道TX0和射频通道TXn上的信号为第一信号,射频通道TX1和射频通道TXn-1所连接的移相器为相位动态调整的移相器,射频通道TX1和射频通道TXn-1上的信号为第二信号。经过功率电桥处理后,射频通道TX1的信号汇聚到射频通道TX0,射频通道TXn-1的信号汇聚到射频通道TXn,即基站通过功率电桥将第一信号叠加至第二信号,叠加后射频通道TX0和射频通道TXn上的信号功率为2*x,射频通道TX1和射频通道TXn-1上的信号功率为0。
请参阅图5,图5为本申请实施例中基站基于基带权值和电桥参数处理射频通道的信号的示意图。如图5所示,其中(a)图为公共信道的信号处理示意图,(b)图为业务信道的信号处理示意图。在(a)图所示的实施例中,假设公共信道TX0和公共信道TX1上的信号都为S0,公共信道TXn-1和公共信道TXn上的信号都为Sn-2,其中公共信道TX0和TXn连接相位固定的移相器,公共信道TX1和公共信道TXn-1连接相位可动态调整的移相器,经过功率电桥处理后,公共信道TX0和公共信道TXn的信号为2*S0,公共信道TX1和公共信道TXn-1的信号为0。
在(b)图所示的示例中,假设业务信道TX0上的信号为(S0-j*S1)/2,业务信道TX1上的信号为(S0+j*S1)/2,业务信道TXn-1上的信号都为(Sn-1+j*Sn-2)/2,业务信道TXn的信号为(Sn-1-j*Sn-2)/2,其中业务信道TX0和TXn连接相位固定的移相器,业务信道TX1和业务信道TXn-1连接相位可动态调整的移相器,经过功率电桥处理后,业务信道TX0的信号为S0,业务信道TX1的信号为S1,业务信道TXn-1的信号为Sn-2,业务信道TXn的信号为Sn-1。
请参阅图6,图6为本申请实施例提供的波束覆盖的对比示意图。如图6所示,其中(a)图为引入功率电桥之前的不同射频通道的功率示意图和波束覆盖范围的示意图,信号虽然通过射频通道相位固定的移相器发送,但是信号的功率没有叠加在相位固定的移相器所在的射频通道,使得信号的功率下降,波束的覆盖范围收缩。
如图6所示,(b)图为引入功率电桥之后的不同射频通道的功率示意图和波束覆盖范 围的示意图,信号经过功率电桥处理后通过射频通道相位固定的移相器发送,原本去往相位动态调整的移相器的信号的功率与原本去往相位固定的移相器的信号的功率叠加,使得发送的信号的功率不下降,波束的覆盖范围也不会收缩。
在一个图6所示的一个示例中,以NR公共信道发送SSB为例,若SSB在全部射频通道发送,则SSB发送波束形状随着移相器相位动态变化,NR小区的同步信号和广播信号有较大波动,因此NR小区内的用户,特别是小区边缘用户接入成功率下降,为了解决上述问题,NR公共信道的SSB只在移相器相位固定的射频通道发送,虽然NR SSB的发送波束是固定的,但由于发送通道数减少一半,总的发送功率降低一半,因此NR小区的覆盖范围会收缩。
本申请实施例中NR公共信道的SSB也是在全部射频通道发送,NR公共信道的SSB总的发射功率是一样的,但SSB经过功率电桥后汇聚到移相器相位固定的天线阵列发送,因此发送波束是稳定的,从而提升了小区用户接入成功率。由于本申请实施例SSB在全部射频通道发送,相比SSB只在移相器相位固定的射频通道发送的方案,SSB的发送射频通道数增加了一倍,即SSB总的发送功率提升一倍,进而提升了小区覆盖范围。
上面介绍本申请实施例提供的信号处理方法,下面结合附图介绍本申请实施例涉及的相关装置。
