Description
本申请涉及通信领域,尤其涉及一种通信装置和网络设备。
无线通信技术经历了从模拟通信到数字通信、从单载波(singlecarrier)通信到多载波(multi-carrier)通信,从单模(single-mode)通信到多模(multi-mode)通信的发展阶段。目前,多频段(multi-frequency band)通信技术正成为各大通信设备商和研究机构聚焦的下一个新热点。
频段是指分布在一定带宽内的频谱资源,多频段是两个或两个以上频段的组合。例如,通用移动通信系统(UniversalMobile Telecommunications System,UMTS)中Band1频段下行为2110~2170MHz,上行为1920~1980MHz;时分同步的码分多址技术(Time Division-Synchronous Code Division Multiple Access,TD-SCDMA)中A频段为1880~1900MHz,B频段为2010~2025MHz。
多频段通信系统可以采用一个多频收发信机(Transceiver)同时接收和发送多个频段的射频信号。然而,当前主流的多频收发信机往往存在体积庞大、成本高的缺点。因此,需要研究成本更低、体积更小的多频通信装置。

为了使本技术领域的人员更好地理解本申请实施例方案,下面将结合本申请实施例中的附图,对本申请实施例中的技术方案进行清楚地描述,显然,所描述的实施例仅仅是本申请一部分的实施例,而不是全部的实施例。
本申请的说明书实施例和权利要求书及上述附图中的术语“第一”、“第二”、和“第三”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。此外,术语“包括”和“具有”以及他们的任何变形,意图在于覆盖不排他的包含,例如,包含了一系列步骤或单元。方法、系统、产品或设备不必限于清楚地列出的那些步骤或单元,而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。
如背景技术部分所述,当前主流的多频收发信机往往存在体积庞大、成本高的缺点。因此,需要研究成本更低、体积更小的多频通信装置。本申请实施例提供的通信装置通过一个处理电路(发射处理电路或者接收处理电路)和一个滤波器(发射滤波器或者接收滤波器)来实现两个或两个以上独立的频段信号的发射或接收,即两个或两个以上独立的频段信号共用同一个处理电路和一个滤波器(对应于一个发射机或者接收机)。由于本申请实施例提供的通信装置中的滤波器的数量相比于其他多频通信装置中的滤波器的数量较少,因此本申请实施例提供的通信装置的成本更低、体积更小。另外,由于本申请实施例提供的通信装置中的滤波器数量较少,因此滤波器合路的路数较少,多工器的实现难度也较低。
本申请实施例提供的通信装置通过一个处理电路和一个滤波器处理的两个或两个以上独立的频段具备如下特征:上述两个或两个以上独立的频段中任意两个相邻的频段之间的 带宽间隔均小于第一阈值。可选的,上述两个或两个以上独立的频段分别包含于3GPP定义的不同的频段,即任意两个频段都不包含于同一个3GPP定义的频段。该第一阈值可以是0MHz、3MHz、5MHz、10MHz、20M等,本申请不作限定。由于上述两个或两个以上独立的频段中任意两个相邻的频段之间的带宽间隔均小于第一阈值,因此这些独立的频段可以作为一个频段共用同一个处理电路和一个滤波器。假定上述两个或两个以上独立的频段为第一频段、第二频段以及第三频段,且该第一频段、该第二频段以及该第三频段对应的频率递增或递减,则该三个频段中任意两个相邻的频段之间的带宽间隔包括该第一频段和该第二频段之间的带宽间隔,以及该第二频段和该第三频段之间的带宽间隔。两个频段之间的带宽间隔可以是频率较低的频段的截止频点与频率较高的频段的起始频点之间的间隔。举例来说,某个频段的范围为758~788MHz,该频段的起始频点为758MHz,该频段的截止频点为788MHz。又举例来说,第一频段的范围为758~788MHz,第二频段的范围为791~821MHz,该第一频段和该第二频段之间的带宽间隔为3MHz(即(791-788)MHz)。下面结合附图来介绍本申请实施例提供的通信装置通过一个处理电路和一个滤波器处理的两个或两个以上独立的频段的举例。

第一接收处理电路1102,用于接收上述第一接收滤波器输入的上述第一接收频段的信号和上述第二接收频段的信号。
图11中的通信装置110可以是无线电接收机。无线电接收机是接收无线电信号,并将它转换为原传送电信号(如声频信号、电视信号等)的设备。按电信号类别、电波频率和解调方法,无线电接收机可分为电报收信机、电话收信机、广播接收机(收音机)、电视接收机和调频接收机等多种类型。可选的,上述一接收频段和上述第二接收频段分别包含于3GPP定义的不同的发射频段。也就是说,上述第一接收频段和上述第二接收频段为两个独立的接收频段。示例性的,上述第一接收频段和上述第二接收频段中的一个包括832~862MHz中的部分频段,另一个包括880~915MHz中的部分频段。示例性的,上述第一接收频段和上述第二接收频段中的一个包括777~787MHz中的部分频段,另一个包括788~798MHz中的部分频段。
图12为本申请实施例提供另一种通信装置120的结构示意图。图12中的通信装置120相比于图11中的通信装置110还包括:第二接收处理电路1201和与第二接收处理电路1201连接的第二接收滤波器1202;
第二接收滤波器1202,用于对输入的信号进行过滤以得到第三接收频段的信号,上述第三接收频段和上述第一接收频段之间的带宽间隔大于上述第二阈值,上述第三接收频段和上述第二接收频段之间的带宽间隔大于上述第二阈值;
第二接收处理电路1201,用于接收上述第二接收滤波器输入的上述第三接收频段的信号。
在一些实施例中,第一接收滤波器1102和第二接收滤波器1202连接同一个天线端口。可选的,第一接收滤波器1102和第二接收滤波器1202包含于同一个双工器。示例性的,上述第一接收频段包括832~862MHz中的部分频段,上述第二接收频段包括880~915MHz中的部分频段,上述第三接收频段包括703~733MHz中的部分频段。在一些实施例中,第一接收滤波器1102可过滤接收频段为832~862MHz的信号和接收频段为880~915MHz的信号,第二接收滤波器1202可过滤接收频段为703~733MHz的信号。示例性的,上述第一接收频段包括777~787MHz中的部分频段,上述第二接收频段包括788~798MHz中的部分频段,上述第三接收频段包括699~716MHz中的部分频段。在一些实施例中,第一接收滤波器1102可过滤接收频段为777~787MHz的信号和接收频段为788~798MHz的信号,第二接收滤波器1202可过滤接收频段为699~716MHz的信号。可以理解,通信装置120中的双工器可过滤3个独立的接收频段的信号。也就是说,通信装置可实现滤波器多频共用,即两 个或两个以上接收频段共用同一个滤波器,能够减少滤波器的合路路数,多工器的实现难度较低。另外,第一接收处理电路1101和第一接收滤波器1102对应于一个接收机。也就是说,图11和图12中的通信装置中的一个接收机可以接收两个独立频段的信号,接收机的数量较少。
前述实施例未描述通信装置的发射信号过程,下面介绍图4至图6中的通信装置可实现的一种发射信号过程。
示例性的,图4至图6中的通信装置实现的一种发射信号过程如下:

2)、第一发射滤波器302对第一发射频段的信号、第二发射频段的信号、以及第四发射频段的信号进行滤波后,通过天线端口将信号发射出去。
示例性的,上述第一发射频段包括729~746MHz中的部分频段,上述第二发射频段包括746~756MHz中的部分频段,上述第四发射频段包括756~768MHz中的部分频段。示例性的,上述第一发射频段包括746~756MHz中的部分频段,上述第二发射频段包括756~768MHz中的部分频段,上述第四发射频段包括729~746MHz中的部分频段。示例性的,上述第一发射频段包括729~746MHz中的部分频段,上述第二发射频段包括756~768MHz中的部分频段,上述第四发射频段包括746~756MHz中的部分频段。在该实施例中,通信装置通过一个发射处理电路和一个发射滤波器可以发射3个独立的频段的信号,发射机和滤波器的数量均较少,使得该通信装置的体积较少、实现简单。
前述实施例未描述通信装置的发射信号过程,下面以Band A、Band B和Band C为例介绍通信装置可实现的一种接收信号过程。
示例性的,图6、图9以及图12中的通信装置实现的一种接收信号过程如下:
1)通信装置通过单独的接收滤波器和接收处理电路(即接收机)对接收到的Band A的信号进行滤波、放大等处理后送入下级信号处理单元;
2)、对于Band B和Band C的接收信号,通信装置通过一个接收滤波器对信号进行滤波,接收滤波器输出的Band B和BandC的双频信号通过共用的接收处理电路(即接收机)对双频信号进行放大等处理后送入下级信号处理单元。
示例性的,通信装置60通过第一接收处理电路501和第一接收滤波器502对第一接收频段(对应于Band B,例如832~862MHz)的信号和第二接收频段(对应于Band C,例如880~915MHz)的信号进行滤波、放大等处理;通过第二接收处理电路601和第二接收滤波器602对第三接收频段(对应于Band A,例如703~733MHz)的信号进行滤波、放大等处理。示例性的,通信装置90通过第三接收处理电路801和第三接收滤波器802对第四接收频段(对应于Band B,例如777~787MHz)的信号和第五接收频段(对应于Band C,例如788~798MHz)的信号进行滤波、放大等处理;通过第四接收处理电路901和第四接收滤波器902对第六接收频段(对应于Band A,例如699~716MHz)的信号进行滤波、放大等处理。在该实施例中,通信装置通过两个接收处理电路和两个接收滤波器可以接收3个独立的频段的信号,接收机和滤波器的数量均较少,使得该通信装置的体积较少、实现简单。
本申请实施例还提供了一种网络设备,包括前述实施例所述的任一通信装置。可选的,该网络设备为一个基站。
