Definitions
- the embodiments of the present invention relate to the field of communications technologies, and in particular, to a method, an apparatus, and a terminal for selecting an antenna.
- a directional antenna In the existing wireless communication system, in order to improve the transmission and reception performance of the terminal, a directional antenna is usually employed. Since the directional antenna has the characteristics of electromagnetic wave intensity and long radiation distance transmitted and received in the directional direction, when the directional direction of the directional antenna is set to point to the base station, the terminal can obtain a higher antenna gain. However, the beam of the directional antenna is very narrow. Such an antenna increases the difficulty of antenna alignment during the installation process, which is technically difficult and increases the labor cost. Even after successful installation, the transceiver performance of the terminal will decrease as the surrounding environment changes. For example: there is building occlusion, or the terminal itself moves, or the network side equipment has been adjusted. It can be seen that there is a limitation in the direction of the directional antenna.
- the omnidirectional antenna exhibits 360-degree uniform radiation in the horizontal direction, so there is no need to set the orientation direction, and the installation process is not technically difficult, which can save labor costs. And the omnidirectional antenna can adapt to changes in the surrounding environment, and no direction adjustment is needed.
- the omnidirectional antenna has the characteristics that the electromagnetic waves transmitted and received in various directions are weak and the radiation distance is short, and thus the transmission and reception performance of the terminal is also limited.
- the present application provides a method, an apparatus, and a terminal for selecting an antenna, which are used to solve the problem that it is difficult to improve both the directivity problem of the terminal antenna and the antenna gain in all directions.

- the terminal periodically detects the M directional antennas included in the first group, and acquires the second downlink signal parameter. If the average value of the second downlink signal parameter of the first packet is compared with the average value of the first downlink signal parameter of the first packet, the amount of decrease is greater than the first threshold, indicating that the directional antenna of the first packet of the receiving antenna of the terminal The signal strength or quality is degraded, and the terminal needs to re-determine the receiving antenna and the transmitting antenna. The terminal may re-measure the N directional antennas to obtain the third downlink signal parameter. Among the P packets, the directional antenna in the packet with the largest average value of the third downlink signal parameter is used as the new receiving antenna and the transmitting antenna.

Abstract
本申请公开一种天线的选择方法、装置及终端,用以解决现有技术中难以同时解决天线的方向性问题和天线增益的问题。本申请的方法可应用于终端,终端具有N个定向天线,且这N个定向天线呈环形放置,该方法包括;终端获取这N个定向天线的每个定向天线的第一下行信号参数,其中,第一下行信号参数包括下行信号强度和下行信号质量。终端根据第一下行信号参数从N个定向天线中选取M个定向天线作为该终端的接收天线,从M个定向天线中选取L个定向天线作为该终端的发射天线。本发明实施例应用于终端与基站的通信中。
Description
本发明实施例涉及通信技术领域,尤其涉及一种天线的选择方法、装置及终端。
在现有的无线通信系统中,为了提升终端收发性能,通常采用定向天线。因为定向天线具有在定向方向上发射及接收的电磁波强、辐射距离远的特点,所以当定向天线的定向方向设置为指向基站时,终端能够获得较高的天线增益。然而定向天线的波束非常窄,这样的天线在安装过程中会增加天线对准难度,技术难度大,增加了人工成本。即使成功安装完,终端的收发性能也会随着周围环境的变化而降低。例如:有建筑物遮挡、或终端自身发生移动,或网络侧设备发生了调整等等。可见,定向天线存在方向上的局限性问题。
为了解决定向天线的方向局限性问题,部分厂商选择使用全向天线。这是因为全向天线在水平方向表现为360度均匀辐射,因此不需要设置定向方向,安装过程技术难度不大,能够节省人力成本。并且在全向天线能够适应周围环境的变化,不需要进行方向调整。但全向天线具有在各个方向上发射及接收的电磁波较弱,辐射距离较短的特点,因此终端的收发性能也受限。
然而,随着用户对终端性能的要求越来越高,在解决终端天线的方向性问题的前提下,提升天线增益,已成为亟待解决的问题。
发明内容
本申请提供一种天线的选择方法、装置及终端,用以解决难以既改善终端天线的方向性问题,又能提升在各个方向上的天线增益的问题。
为达到上述目的,本申请的实施例采用如下技术方案:
第一方面,本申请实施例提供一种天线选择的方法,应用于终端,该终端具有N个呈环形放置的定向天线,每个定向天线的定向方向设置为与环形的切线方向垂直,且指向环形外侧,该方法具有包括:终端获取这N个定向天线的每个定向天线的第一下行信号参数,并根据第一下行信号参数从N个定向天线中选取M个定向天线作为该终端的接收天线,从M个定向天线中选取L个定向天线作为该终端的发射天线。由此,本申请通过将N个定向天线环形放置使得终端能够获取360度的信号辐射范围,并根据第一下行信号参数从N个定向天线中确定第一下行信号参数最高的定向天线为终端的接收天线和发射天线,从而提升终端的天线增益,有利于提高终端的通信质量。
其中,第一下行信号参数包括下行信号质量或下行信号强度。N≥2,N≥M≥L,且L、M、N为正整数。
在一种可能的设计中,在终端获取这N个定向天线的每个定向天线的第一下行信号参数之前,终端可将这N个定向天线划分为P个分组,其中每一个分组中包含M个定向天线。这样,终端以分组为单位进行确定接收天线组,可减少定向天线的组合
数量,以及减少具体实现时需要的开关数量,有利于简化终端的选择过程。
在一种可能的设计中,若终端对N个定向天线进行了分组,那么,终端可根据各个定向天线的第一下行信号参数获取每个分组的第一下行信号参数的平均值。再选取每个分组的第一下行信号参数的平均值最大的分组为第一分组,选取第一分组中包括的M个定向天线作为该终端的接收天线。对第一分组中的M个定向天线再按照第一下行信号参数从高到低进行排序,选择其中最大的L个定向天线作为终端的发射天线。这样,终端拥有信号强度或质量最好的定向天线作为接收天线和发射天线,有利于提终端的收发性能,提高终端的通信质量。
在一种可能的设计中,终端对第一分组包括的M个定向天线进行周期性检测,获取第二下行信号参数。若第一分组的第二下行信号参数的平均值与第一分组的第一下行信号参数的平均值比较,下降量大于了第一阈值,表明作为终端的接收天线的第一分组的定向天线的信号强度或质量变差,终端需要重新确定接收天线和发射天线。终端可对N个定向天线重新进行测量,获取第三下行信号参数。选取P个分组中,第三下行信号参数的平均值最大的分组中的定向天线作为新的接收天线和发射天线。由此,当作为接收天线和发射天线的定向天线的信号变差时,终端可以重新获取信号好的定向天线作为接收天线和发射天线,有利于提高终端的收发性能,有利于提高终端的通信质量。
在一种可能的设计中,终端周期性对N个定向天线都进行检测,获取每个定向天线的第四下行信号参数,进一步获取每个分组的第四下行信号参数的平均值,直接选取第四下行信号参数的平均值最大的分组为第二分组,选取第二分组包括的M个定向天线作为新的接收天线,再选取这M个定向天线中第四下行信号参数最大的L个定向天线作为发射天线。这样,当N个定向天线中,有其他定向天线的信号变好时,直接选择信号好的作为终端新的接收天线和发射天线,有利于提高终端的收发性能,有利于提高终端的通信质量。
在一种可能的设计中,在确定第二分组中的M个定向天线作为终端的接收天线之前,可以先判断一下第二分组的第四下行信号参数的平均值是否大于一定程度,例如:大于第一分组的第四下行信号参数平均值的第一预设倍数。若大于,则重新确定第二分组中的M个定向天线作为该终端的接收天线,其中第四下行信号参数最大的L个定向天线作为该终端的发射天线。
若小于或等于,则不重新确定接收天线。但需要进一步确定是否需要重新确定发射天线。获取第一分组中作为发射天线的L个定向天线的第四下行信号参数的平均值,即第一平均值;终端按照第四下行信号参数进行排序,选取其中第四下行信号参数最大的L个定向天线,计算着L个定向天线的第四下行信号参数的平均值,即第二平均值。如第二平均值大于第一平均值的第二预设倍数,则终端重新确定这L个定向天线为新的发射天线。如第二平均值小于或等于第一平均值的第二预设倍数,则终端也不需要重新确定发射天线。
在一种可能的设计中,若终端没有对这N个定向天线进行分组,那么,终端直接选取第一下行信号参数最大的M个定向天线作为终端的接收天线,选取第一下行信号
参数最大的L个定向天线作为终端的发射天线。
在一种可能的设计中,终端获取作为接收天线的这M个定向天线的第一下行信号参数的平均值,即第三平均值;终端对这M个定向天线进行周期性检查,获取第五下行参数,并获取这M个定向天线的第五下行参数的平均值,即第四平均值。
若第四平均值相对于第三平均值的下降量大于了第二阈值,表明作为接收天线的这M个定向天线的信号变差,则终端需要重新确定接收天线的发射天线。故终端对N个定向天线都进行检测,获取每个定向天线的第六下行信号参数。根据每个定向天线的第六下行信号参数重新确定终端的接收天线和发射天线。

若第六平均值等于或小于第五平均值,则终端不需要重新确定接收天线,但需进一步判断是否需要重新确定发射天线。获取作为发射天线的L个定向天线的第七下行信号参数的平均值,即第七平均值。再获取第七下行信号参数最大的L个定向天线,并计算这L个定向天线的第七下行信号参数的平均值,即第八平均值。
若第八平均值大于第七平均值的第四预设倍数,则终端重新确定按照第七下行信号参数排序后,前L个定向天线作为终端的发射天线。若第八平均值小于或等于第七平均值的第四预设倍数,则终端也不需要重新确定发射天线。

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。
在现有无线通信网络中,通常包括终端101和基站102。若终端101采用定向天线,该定向天线的定向方向指向基站102,则该定向天线的辐射范围如图1a所示,在定向方向上辐射有较强的电磁波,天线增益大,而在其他方向上电磁波较弱,甚至没有。若终端101采用全向天线,则全向天线的辐射范围如图1b所示,在终端101周围的方向上辐射有相同的强度的电磁波,但辐射距离较短,天线增益小。因此,若终端采用本申请实施例提供的方法,则该终端天线的辐射范围可如图2所示,既能保证终端天线的方向性,又能提高各个方向上的天线增益。
图3为本申请实施例中终端的一种结构示意图,可应用于上述的网络中。其中,该终端可为无线客户终端设备(Customer Premise Equipment,CPE)、无线上网设备等。在本申请实施例中,该终端300可以包括处理模块301、通信模块302、存储模块303以及天线模块304。
其中,处理模块301用于控制网络设备300的各部分硬件装置和应用程序软件等。在本申请实施例中,处理模块31例如可用于通过天线模块304获取每个定向天线的下行信号参数,计算每个分组中定向天线的下行信号参数的平均值,对各个定向天线按照下行信号参数从高到低的顺序进行排序,以及从N个定向天线中确定M个定向天线作为终端的接收天线,从M个定向天线中确定L个定向天线作为所述终端的发射天线等等。
通信模块302用于可使用无线保真(Wireless Fidelity,WiFi)、长期演进(Long Term Evolution,LTE)以及5G等通讯方式接受其它设备发送的指令和数据,也可以向其它设备发送指令和数据。在本申请实施例中,通信模块302可以用于接收其他网络设备发送的建路请求及业务数据,也用于向其他网络设备发送建路请求及业务数据等。
存储模块303用于执行网络设备300的软件程序的存储、数据的存储和软件的运行等。在本申请实施例中,存储模块303例如可以用于存储每个定向天线的下行信号参数,分组中天线的信息等等。
天线模块304包括N个定向天线,并且这N个定向天线呈环形放置。其中,如图4所示,每个定向天线的定向方向设置为垂直于环形的切线方向,且指向环形外侧。可选的,为了提升终端的分集增益,可增加这N个定向天线的间距,如图5所示,这N个定向天线也可以分成多层,每层的天线在水平面上环形放置,其中,每个定向天线的定向方向设置为垂直于环形的切线方向,且指向环形外侧。需要说明是,图4和图5仅示出了8个定位天线,即N为8的情况,但本申请实施例并不限定定向天线的
数量、分层的数量以及具体的放置位置等。
在本申请实施例中,各模块的具体功能在下述实施例中说明。
如图6所示,本申请实施例提供的一种天线选择的方法可运用于上述终端中,该方法具体包括:
101、终端获取每个定向天线的第一下行信号参数。
其中,第一下行信号参数包括下行信号强度或下行信号质量。具体的,可用参考信号接收功率(Reference Signal Receiving Power,RSRP)来表征下行信号强度,可用信号与干扰加噪声比(Signal to Interference plus Noise Ratio,SINR)来表征下行信号质量。下行信号强度越强,或者下行信号质量越好,表明该天线的收发性能越好。
具体的,终端在开机后,终端使用小区搜索过程来识别小区,并获得下行同步,进而终端可以读取小区广播信息并驻留、使用网络提供的各种服务。在小区搜索过程中,终端分别在各个定向天线上检测小区的同步信道或小区导频信号,获得各个定向天线上的信道估计值和干扰信息,再由各个定向天线上的信道估计值得到各个定向天线的下行信号强度,由各个定向天线上的信道估计值和干扰信息得到各个定向天线上的下行信号质量。
102、终端根据每个定向天线的第一下行信号参数,从N个定向天线中确定M个定向天线为该终端的接收天线,从M个定向天线中确定L个定向天线为终端的发射天线。
其中,接收天线和发射天线的数量分别都是根据终端的基带芯片的能力确定的。确定终端的基带芯片能够支持的接收天线的数量为M,基带芯片能够支持的发射天线的数量为L。其中,基带芯片是用来合成即将发射的基带信号,或对接收到的基带信号进行解码。具体地说,就是发射时,把音频信号编译成用来发射的基带码;接收时,把收到的基带码解译为音频信号。同时,也负责地址信息(手机号、网站地址)、文字信息(短讯文字、网站文字)、图片信息的编译。
一种可能的实现方式中,按照第一下行信号参数对这N个定向天线进行从高到低的排序,从这N个定向天线中选取第一下行信号参数最大的M个定向天线为该终端的接收天线,再从这M个定向天线中选取第一下行信号参数最大的L个定向天线为该终端的发射天线。示例性的,如图4或图5所示,该终端包括8个定位天线,且该终端的基带芯片支持的接收天线为4个,支持的发送天线为2个。终端在这8个天线上检测小区的导频信号,得到这8个定位天线中的信号强度和/或信号质量。假设这8个定位天线中的第一下行信号参数从高到低的排序为:天线1>天线2>天线3>天线4>天线5>天线6>天线7>天线8,则终端确定天线1、天线2、天线3和天线4为接收天线,天线1和天线2为发送天线。
另一种可能的实现方式中,考虑到终端需从N个定向天线中选取M个定向天线作为终端的接收天线的天线组合有很多种情况,而针对这么多组合情况,终端具体实现时会十分复杂,例如:需要的开关数量也大,并且开关越多,信号的衰减量越大、处理量也越大。因此,为简化终端在选择天线时的复杂程度,减少组合情况,在本申请实施例中,也可以将这N个定向天线进行分组,以分组为单位进行选择。分组的方
法可以为相邻的M个定向天线为一组,组之间的定向天线可以重叠,也可以不重叠,N个定向天线分成P个分组。分组之后,终端将各个分组中的M个定向天线的第一下行信号参数求平均值,得到各个分组的第一下行信号参数的平均值。然后,确定各个分组中下行信号参数平均值最大的分组,即第一分组,将第一分组中的M个定向天线作为终端接收天线组。在对第一分组中M个定向天线按照第一下行参数从高到低的顺序进行排序,选取第一分组中M个定向天线的前L个定向天线为该终端的发射天线。
示例性的,如图7所示,该终端包括8个定位天线,且该终端的基带芯片支持的接收天线为4个,支持的发送天线为2个。那么,该终端的8个定向天线可划分为3个分组:分组1包括天线1-天线4;分组2包括天线3-天线6;分组3包括天线6-天线8以及天线1。分组之间的定向天线有重叠,例如分组1和分组2中都包括天线3和天线4;分组2和分组3中都包括天线6;分组3和分组1中都包括天线1。
假设这3个分组的第一下行信号参数的平均值的关系为:分组3>分组2>分组1,则该终端确定分组3中的4个定位天线(天线6、天线7、天线8和天线1)为接收天线,再从分组3中的确定信号强度和/或信号质量最大的2个定位天线为发射天线。
本申请实施例提供的一种天线的选择的方法,应用于包含N个定向天线且所述N个定向天线呈环形放置的终端中,根据每个定向天线的下行信号参数,确定其中M个定向天线为终端的接收天线,确定其中L个定向天线为终端的发射天线。与现有技术相比较,现有技术中终端使用定向天线获取天线增益,但若周围环境的变化,则终端的通信质量会下降,需要人工调整天线的方向。或者通过全向天线获取360度的信号辐射范围,以便适应周围环境的变化,不需要进行人工调整天线方向,但全向天线的天线增益小,也会影响终端的收发性能。而本申请通过将N个定向天线环形放置使得终端能够获取360度的信号辐射范围,并根据第一下行信号参数从N个定向天线中确定第一下行信号参数最高的M个定向天线为终端的接收天线,从M个定向天线中确定第一下行信号参数最高的L个定向天线为终端的发射天线,从而提升终端的天线增益。
此外,本申请实施例中,每个定向天线的定向方向设置为垂直于环形的切线方向,且指向环形外侧即可,不用严格的将定向方向设置为指向基站,降低了定向天线安装时的技术难度,节省了人力成本。而且,本申请实施例中通过从N个定向天线中自动确定第一下行信号参数最高的定向天线作为终端接收天线,能够适应周围环境的变化,不需要人工的对天线进行调整,也节省了人力成本。
终端在接入无线网后,可继续采用终端开机时确定的接收天线和发送天线进行通信,也可以根据下行信号参数的变化来重新确定该终端的接收天线和发射天线。下面分情况对天线的选择方法进行说明。
一、对终端的N个定向天线进行了分组。
考虑到终端入网后,随着周围环境发生变化,原先确定的M个接收天线上信号强度或质量可能会变差的情况,终端需要确定是否需要确定接收天线和发射天线。于是,如图8所示,本申请实施例还提供了一种天线选择的方法,在步骤102之后,具体包括:
201、在第一预设时间段后,终端获取第一分组的中的M个定向天线的第二下行
信号参数,进而获取第一分组的第二下行信号参数的平均值。
其中,第二下行信号参数包括下行信号强度或下行信号质量。第一分组的第二下行信号参数的平均值即为第一分组中包括的M个定向天线的第二下行信号参数的平均值。
具体的,根据步骤102可知,终端在开机后确定第一分组中的M个定向天线作为该终端的接收天线。那么,在入网后,终端实时或者按照一定周期,即第一周期,在这M个定向天线上检测小区导频信号,进而获得这M个定向天线中每个天线上的第二下行信号参数,以及这M个定向天线的第二下行信号参数的平均值。
202、终端判断第一分组的第二下行信号参数的平均值,相比较于第一分组的第一下行信号参数的平均值的下降量是否大于第一阈值。若是,执行步骤203。若否,执行步骤205。
若第一分组的第二下行信号参数的平均值,相比较于第一分组的第一下行信号参数的平均值的下降量大于第一阈值,表明第一分组中的这M个定向天线上的信号强度或质量总体变差,且变差达到一定程度,终端的通信质量可能会受到影响,则终端需要重新确定接收天线和发射天线。
进一步的,为了增加系统的鲁棒性,避免第一分组中这M个定向天线上的信号强度或质量有短暂的下降,终端就重新确定接收天线和发射天线的情况发生。可以在检测到第一分组中这M个定向天线的第二下行信号参数的平均值,相较于第一下行信号参数的平均值的下降量在一定的时间段内连续多次超过第一阈值时,终端才认为第一分组中的M个定向天线上的信号强度或质量变差,终端需要重新确定接收天线和发射天线。
若第一分组的第二下行信号参数的平均值,相比较于第一分组的第一下行信号参数的平均值的下降量小于或等于第一阈值,表明第一分组的M个定向天线上的信号强度或质量总体上没有变差,或者只有少许的变差,终端的通信质量不会受到较大的影响。因此,不需要重新确定终端的接收天线和发射天线。
203、终端获取终端N个定向天线上的第三下行信号参数。
其中,第三下行信号参数包括下行信号强度或下行信号质量。
具体的,终端对全部的N个定向天线上的小区导频信号都进行检测,获取N个定向天线上的第三下行信号参数。
204、终端根据第三下行信号参数重新确定终端的接收天线和发射天线。
具体的实现方式可参考步骤102,在此不重复赘述。
205、终端确定继续使用之前确定的接收天线和发射天线。
由此,当终端在入网后,之前确定第一分组的M个接收天线的信号强度或质量下降时,且下降时达到一定程度时,终端可以重新确定信号强度或质量最好的定向天线为接收天线和发射天线。这样,可以避免原先确定的接收天线和发射天线上的信号强度或质量变差而造成终端的通信质量下降。
进一步的,考虑到终端入网后,虽然终端原先确定第一分组中的M个定向天线的信号强度或质量没有变差,但该终端的其他分组中的定向天线上的信号强度或质量有
可能变的更好,从而导致该终端上的通信质量不是最好的。于是,如图9所示,本申请实施例还提供了一种天线选择的方法,在步骤102之后,具体包括:
301、终端在第二预设时间段后获得N个定向天线上每个定向天线的第四下行信号参数,以及各个分组的第四下行信号参数的平均值。
其中,第四下行信号参数包括下行信号强度或下行信号质量。各个分组的第四下行信号参数的平均值即为各个分组中包括的M个定向天线的第二下行信号参数的平均值。
具体的,终端按照一定周期,即第二周期,对N个定向天线上的小区导频信号进行检测,以便观察该终端上各个定向天线上的信号强度或质量是否有变好。
302、终端根据各个分组的第四下行信号参数的平均值重新确定第二分组中的M个定向天线为新的接收天线,从第二分组中的M个定向天线中确定L个定向天线为新的发射天线。
其中,第二分组为P个分组中第四下行信号参数的平均值最大的分组。
具体的,终端重新确定第二分组中的M个定向天线作为该终端新的接收天线。然后,终端按照第四下行信号参数从高到低的顺序将重新选取的第二分组中的M个定向天线进行排序,获取其中前L个定向天线作为该终端的发射天线。这样,终端更新接收天线和发射天线有利于提高终端的收发性能,提高通话质量。
进一步,为了增加系统的鲁棒性,避免其他分组的定向天线上信号强度或质量稍有变好,终端就重新确定接收天线和发射天线的情况发生,如图10所示,本申请实施例还提供了一种天线选择的方法,在步骤302之前,具体包括:
401、若第二分组的第四下行信号参数的平均值大于第一分组的第四下行信号参数的平均值的第一预设倍数,则执行步骤302。否则执行步骤402。
其中,第二分组为P个分组中第四下行信号参数的平均值最大的分组。
具体的,若第二分组的第四下行信号参数的平均值大于第一分组的第四下行信号参数的平均值的第一预设倍数,例如:1.2倍,表明第二分组的定向天线上的信号强度或质量,相对于第一分组中作为接收天线的M个定向天线,总体上有变好且变好达到一定程度。那么,终端需要重新确定接收天线和发射天线。
若第二分组的第四下行信号参数的平均值小于或等于第一分组的第四下行信号参数的平均值的第一预设倍数,表明第二分组的定向天线上的信号强度或质量,相对于第一分组中作为接收天线的M个定向天线,总体上没有变好且变好没有达到一定程度,则终端不需要重新确定接收天线。需要注意的是,有可能此时第二分组内部的M个定向天线上信号强度或质量有发生变化,因此,需进一步判断是否需要重新确定发射天线。
402、终端根据第四下行信号参数获取第一平均值以及第二平均值。
具体的,终端计算第一分组中作为接收天线的L个定向天线的第四下行信号参数的平均值,即为第一平均值。然后,终端按照第四下行信号参数从高到低的顺序将第一分组中的M个定向天线进行排序,获取第一分组中第四下行信号参数最大的L个定向天线,并计算这L个定向天线的第四下行信号参数的平均值,即为第二平均值。
403、若第二平均值大于第一平均值的第二预设倍数,则终端确定第一分组中第四下行信号参数最大的L个定向天线为终端新的发射天线。
具体的,若第二平均值大于第一平均值的第二预设倍数,例如1.2倍,表明第二分组中M个定向天线内部的信号强度或质量发生了较大的变化,且有除原来作为接收天线的L个的定向天线以外的,其他的天线的信号强度或质量明显变好。于是,终端需要重新确定终端的接收天线,有利于提高终端的发射性能,提高终端的通信质量。否则,终端也不需要重新确定发射天线。
由此,当终端在入网后,之前确定的M个接收天线的信号强度或质量下降时,且下降时达到一定程度时,终端可以重新确定信号强度或质量最好的定向天线为接收天线和发射天线。这样,可以避免原先确定的接收天线和发射天线上的信号强度或质量变差而造成终端的通信质量下降。
二、未对终端的N个定向天线进行分组
考虑到终端入网后,随着周围环境发生变化,原先确定的M个接收天线上信号强度或质量可能会变差的情况,终端需要确定是否需要确定接收天线和发射天线。于是,如图11所示,本申请实施例还提供了一种天线选择的方法,在步骤102之后,具体包括:
501、终端根据作为接收天线的M个定向天线的第一下行信号参数的平均值,即第三平均值。
502、在第三预设时间段后,终端获取该M个定向天线的第五下行信号参数以及第四平均值。
其中,第五下行信号参数包括下行信号强度或下行信号质量,第四平均值为该M个定向天线的第五下行信号参数的平均值。
503、该终端判断第四平均值相比较于第三平均值是否大于第二阈值。若是,执行步骤504。若否,执行步骤506。
若第四平均值相比较于第三平均值的下降量大于第二阈值,表明作为接收天线的这M个定向天线上的信号强度或质量总体变差,且变差达到一定程度,终端的通信质量可能会受到影响,则终端需要重新确定接收天线和发射天线。
进一步的,为了增加系统的鲁棒性,避免作为接收天线的这M个定向天线上的信号强度或质量有短暂的下降,终端就重新确定接收天线和发射天线的情况发生。可以在检测到第四平均值相较于第三平均值的下降量在一定的时间段内连续多次超过第二阈值时,终端才认为这M个定向天线上的信号强度或质量变差,终端需要重新确定接收天线和发射天线。
若第四平均值相比较于第三平均值的下降量小于或等于第二阈值,表明作为接收天线的M个定向天线上的信号强度或质量总体上没有变差,或者只有少许的变差,终端的通信质量不会受到较大的影响。因此,不需要重新确定终端的接收天线和发射天线。
504、终端获取终端N个定向天线上的第六下行信号参数。
其中,第六下行信号参数包括下行信号强度或下行信号质量。
505、终端根据第六下行信号参数重新确定终端的接收天线和发射天线。
具体的实现方式可参考步骤102,在此不重复赘述。
506、终端确定继续使用之前确定的接收天线和发射天线。
由此,当终端在入网后,之前确定的M个接收天线的信号强度或质量下降时,且下降时达到一定程度时,终端可以重新确定信号强度或质量最好的定向天线为接收天线和发射天线。这样,可以避免原先确定的接收天线和发射天线上的信号强度或质量变差而造成终端的通信质量下降。
进一步的,考虑到终端入网后,虽然终端原先确定M个定向天线的信号强度或质量没有变差,但该终端的其他定向天线上的信号强度或质量有可能变的更好,从而导致该终端上的通信质量不是最好的。于是,如图12所示,本申请实施例还提供了一种天线选择的方法,在步骤102之后,具体包括:
601、终端在第四预设时间段后获得N个定向天线上每个定向天线的第七下行信号参数。
其中,第七下行信号参数包括下行信号强度或下行信号质量。
具体的,终端按照一定周期,即第四周期,对N个定向天线上的小区导频信号进行检测,以便观察该终端上各个定向天线上的信号强度或质量是否有变好。
602、终端根据每个定向天线的第七下行信号参数重新确定接收天线和发射天线。
具体的,终端按照第七下行信号参数对N个定向天线进行从高到低的排序,重新确定此次排序后的N个定向天线中前M个定向天线为接收天线,前L个定向天线为发射天线。这样,终端更新接收天线和发射天线有利于提高终端的收发性能,提高通话质量。
进一步,为了增加系统的鲁棒性,避免其他定向天线上信号强度或质量稍有变好,终端就重新确定接收天线和发射天线的情况发生,如图13所示,本申请实施例还提供了一种天线选择的方法,在步骤602之前,具体包括:
701、终端根据这N个定向天线的第七下行信号参数获取第五平均值和第六平均值。
其中,第五平均值为此时作为接收天线的M个定向天线的第七下行信号参数的平均值。终端从N个定向天线中选取第七下行信号参数最大的M个定向天线,将这M个定向天线的第七下行信号参数的平均值确定为第六平均值。
702、若第六平均值大于第五平均值的第三预设倍数,则执行步骤602。否则执行步骤703。
具体的,若第六平均值大于第五平均值的第三预设倍数,例如:1.2倍,表明除作为接收天线的M定向天线以外的,其他的定向天线上的信号强度或质量,总体上有变好且变好达到一定程度。那么,终端需要重新确定接收天线和发射天线。
若第六平均值小于或等于第五平均值的第三预设倍数,表明其他定向天线上的信号强度或质量,相对于作为接收天线的M个定向天线,总体上没有变好且变好没有达到一定程度,则终端不需要重新确定接收天线。需要注意的是,有可能此时作为接收天线的M个定向天线之间的信号强度或质量有发生变化,因此,需进一步判断是否需
要重新确定发射天线。
703、终端根据第七下行信号参数获取第七平均值以及第八平均值。
具体的,终端计算作为接收天线的L个定向天线的第七下行信号参数的平均值,即为第七平均值。然后,终端按照第七下行信号参数从高到低的顺序将作为接收天线的M个定向天线进行排序,获取其中第七下行信号参数最大的L个定向天线,并计算这L个定向天线的第七下行信号参数的平均值,即为第八平均值。
704、若第八平均值大于第七平均值的第四预设倍数,则终端确定第七下行信号参数最大的L个定向天线为终端新的发射天线。
具体的,若第八平均值大于第七平均值的第四预设倍数,例如1.2倍,表明作为接收天线的M个定向天线内部的信号强度或质量发生了较大的变化,即有除原来作为接收天线的L个的定向天线以外的,其他的天线的信号强度或质量明显变好。于是,终端需要重新确定终端的发射天线,有利于提高终端的发射性能,提高终端的通信质量。否则,终端不需要重新确定发射天线。
