Description

数据传输的方法和设备 技术领域
本发明涉及通信技术,尤其涉及一种数据传输的方法和设备。
背景技术
在多输入多输出(Multiple Input Multiple Output,以下简称MIMO)通信系统中,通过信号处理能够获得复用增益。其中,复用增益是指在MIMO通信系统中同时利用相同的时频资源传输多流信号获得的容量增益,复用增益的大小与信道的秩有关,秩越大,能够通过信号处理得到的复用增益越大。而信道的秩的大小与信号传播的环境有关,传播环境中散射折射等越丰富,到达接收端多径分量越多,则其对应信道的秩越大。但是,在基站和用户设备之间为视距传播(Line Of Sight,简称LOS)时,即当基站与用户设备之间存在直射路径时,由于直射路径的信号功率远远大于其他路径获得的功率,子信道之间相关性较大,因此信道的秩较低,一般为1,即只支持一个数据流信号的传输,这会使得系统吞吐量受到限制。
现有技术采用增大发射端两个天线之间的传输间距,来降低直射径场景下子信道之间的相关性,从而使得直射径场景下基站和用户设备之间可以进行多流传输,来提升系统的吞吐量。具体为:如图1所示,假设发射端两个天线分别为t1和t2,接收端两个天线分别为r1和r2,传输距离D为发射端和接收端的水平距离,t1和t2之间的间距为dt,r1和r2之间的间距为dr。现有技术中,通过增大D使得t1r2和t2r2之间产生距离差,从而使得这两路上的信号产生相位差,进而使得r2可以识别出这两路信号。采用这种方法,接收端可以识别出不同通路上的数据流,因此,在直射径场景下发射端和接收端可以进行多流传输。
但是,现有技术中,发射端和接收端在直射径场景下进行多流传输时,发射端和接收端的位置是固定的,现有技术无法支持直射径场景下移动用户(移动的接收端)的多流数据传输,适用性低。

图6为本发明提供的数据传输的方法实施例一的流程示意图。该方法的执行主体可以为上述图2或图4所示的数据传输设备,该数据传输设备为第一通信设备,其结构可以参见图2或图4所示,其可以对应执行下述实施例中的方法步骤。本实施例涉及的是第一通信设备通过所获取的满足与第二通信设备进行多流数据传输的第一天线端口,与第二通信设备进行多流数据传输的具体过程。如图6所示,该方法包括:
S101:第一通信设备获取与所述第二通信设备的位置信息对应的第一天线端口;所述第一天线端口为所述第一通信设备上的满足与所述第二通信设备进行多流数据传输条件的天线端口;所述位置信息包括所述第一通信设备和所述第二通信设备之间的视距传输距离,和/或,所述第一通信设备相对于所述第二通信设备的角度信息。
本实施例中,第一通信设备可以看作是发射端设备,则第一通信设备上所选择的用于发射的相邻的天线端口(发射天线)之间的间距即为dt,第二 通信设备可以看作是接收端设备,第二通信设备上所选择的用于接收的相邻的天线端口(接收天线)之间的间距即为dr(dt和dr可以参见图1所示)。由于第二通信设备是可移动的用户设备,因此,第二通信设备与第一通信设备之间的传输距离(可以简称为D)是不固定的。可选的,当dr固定时,离第一通信设备不同距离D的第二通信设备所要求的第一通信设备上的发射天线之间的间距dt是不同的;当dt固定时,离第一通信设备不同传输距离的第二通信设备所要求的自身的接收天线之间的间距dr也是不同的(这是因为在直射径条件下,实现多流传输需要满足传输距离D与发射天线间距dt以及接收天线间距dr之间具有固定的关系)。本发明实施例以dr固定,第一通信设备获取与不同传输距离D下的第二通信设备进行通信的第一天线端口为例来进行说明。可选的,本发明实施例中可以有一个第一天线端口,也可以有多个第一天线端口。
具体的,第一通信设备和第二通信设备上均包括多个天线端口,可选的,第一通信设备可以向与自身具有不同传输距离的第二通信设备提供天线间距与之匹配的天线端口;可选的,第一通信设备可以对自身天线面板上的天线进行分组,不同分组内的天线端口的间距不同,且不同分组内的天线端口可以对应不同传输距离下的第二通信设备;可选的,第一通信设备还可以仅向第二通信设备提供包括多个天线端口的天线面板,通过第一通信设备和第二通信设备之间相应的信令交互确定不同传输距离下的第二通信设备所对应的天线间距适配的天线端口。
本实施例中,第一通信设备获取与第二通信设备的位置信息对应的第一天线端口,可以为第一通信设备主动获取与第二通信设备的位置信息对应的第一天线端口,例如,第一通信设备可以主动获取第二通信设备的位置信息,然后根据第二通信设备的位置信息确定第一天线端口;还可以为第一通信设备被动获取第二通信设备所选择的第一天线端口,例如第二通信设备在根据第二通信设备的位置信息在第一通信设备所提供的天线面板上选择满足与第二通信设备进行多流数据传输的第一天线端口之后,将所选择的第一天线端口上报给第一通信设备,本发明实施例对第一通信设备获取满足与第二通信设备进行多流数据传输的第一天线端口的方式并不做限定,只要其能确保所获取的第一天线端口可以与相应的传输距离下的第二通信设备上的天线端口 能够进行多流数据传输即可。
需要说明的是,上述第二通信设备的位置信息可以包括第一通信设备和第二通信设备之间的视距传输距离,和/或,所述第一通信设备和所述第二通信设备的角度信息。可选的,该视距传输距离可以为第一设备的天线面板的中心与第二设备的天线面板的中心的连线距离或者水平线的距离(即上述的传输距离D),也可以为第一设备上高度最小的天线与第二设备上高度最小天线之间的连线的距离;可选的,该角度信息在实际应用中,可以为第二通信设备的天线与第一通信设备上对应的天线之间的到达角或离开角或与水平方向的夹角,还可以为第二通信设备的天线与第一通信设备上对应的天线在X平面上的夹角或Y平面上的夹角或Z平面上的夹角,还可以为第一设备的天线下倾角或所述第二设备的天线倾角。该第二通信设备的位置信息可以是第一通信设备或第二通信设备通过测量相应的参考信号获取,也可以是通过GPS等定位信息获得,本发明实施例对第二通信设备的位置信息的获取方式并不做限定。
S102:第一通信设备根据所述第一天线端口与所述第二通信设备进行多流数据传输。
具体的,当第一通信设备获取到第一天线端口后,第一通信设备可以通知第二通信设备进入直射径多流传输模式,并根据该第一天线端口与上述位置信息下的第二通信设备进行多流数据传输,即通过该第一天线端口向第二通信设备传输多个数据流。
现有技术中,在直射径场景下,为了使得发射端和接收端之间可以进行多流数据传输,一般是在架设发射端设备和接收端设备时,使发射端天线间距与接收天线间距以及传输距离满足固定的关系(现有技术中的发射端设备和接收端设备均为固定位置的基站设备)实现发射端和接收端可以进行多流传输,但是,现有技术中发射端设备和接收端设备的位置是固定不变的,因而发射端设备上的天线间距和接收端设备上的天线间距也是固定的,即现有技术中的发射端设备上的天线间距和接收端设备上的天线间距无法支持与移动的用户设备之间进行多流数据传输。但是,在本发明实施例中,第一通信设备获取的第一天线端口是与移动的第二通信设备的位置信息相关的,即若第二通信设备移动到某一位置时,第一通信设备所确定的第一天线端口的天 线间距是与该位置的第二通信设备进行多流数据传输时适配的天线间距,故本发明实施例可以支持基站与移动的用户设备间的多流数据传输,提高了视距传播下的多流数据传输系统的适用性。
本发明实施例提供的数据传输的方法,第一通信设备获取与第二通信设备的位置信息对应的第一天线端口,并根据所述第一天线端口与所述第二通信设备进行多流数据传输。本发明实施例提供的方法,可以支持基站与移动的用户设备间的多流数据传输,提高了视距传播下的多流数据传输系统的适用性。
图7为本发明提供的数据传输的方法实施例二的流程示意图。本实施例涉及的是第一通信设备和第二通信设备上均预设有所述第二通信设备的位置信息与所述第一天线端口的映射关系时,第一通信设备获取第一天线端口的具体过程。在上述实施例的基础上,上述S101具体包括:
S201:第一通信设备获取所述第二通信设备的位置信息。
可选的,第一通信设备可以主动获取第二通信设备的位置信息,即第一通信设备可以通过测量相应的参考信号获取第二通信设备的位置信息,例如第一通信设备可以通过测量参考信号的信号接收强度或信干噪比等参数来获取第二通信设备的位置信息;还可以被动的获取第二通信设备的位置信息,即第一通信设备可以接收第二通信设备上报的所述第二通信设备的位置信息,其中,第二通信设备可以通过GPS定位或者其他的位置感知软件来获取自身所处的位置信息。
S202:第一通信设备根据所述第二通信设备的位置信息、所述第二通信设备的位置信息与所述第一天线端口的映射关系获取所述第一天线端口。
具体的,第一通信设备上预设有第二通信设备的位置信息与第一天线端口的映射关系,因此第一通信设备在获取到第二通信设备的位置信息后,就可以根据该第二通信设备的位置信息和上述映射关系确定第一天线端口,可选的,可以是第一通信设备根据第二通信设备的位置信息与上述映射关系进行匹配,将匹配度高于预设阈值的端口确定为第一天线端口。例如,可以参见图8所示,在图8中,针对不同位置信息下的第二通信设备,第一通信设备提供了8个天线端口(8ports)、4ports、2ports、1port四种不同天线 间距的天线端口,且8ports中的天线端口的间距是最小的,即离第一通信设备越近,天线端口的间距越小,离第一通信设备越远,天线端口的间距越大。若第二通信设备位于图8中的A位置,则第一通信设备就根据上述映射关系确定第一天线端口为4ports,4ports中的天线间距(即dt)满足与第二通信设备进行多流数据传输。当然,本实施例中,第二通信设备也会根据所预设的第二通信设备的位置信息与第一天线端口的映射关系确定第一天线端口,即本实施例中,第一通信设备和第二通信设备二者都可以根据第二通信设备的位置信息确定第一天线端口,从而利用该第一天线端口进行多流数据传输。
可选的,上述映射关系可以是在架设第一通信设备时通过软件加载给第一通信设备上的处理器的,也可以是通过其他的网元(例如核心网网元、移动管理实体等)将映射关系发送给第一通信设备的。
可选的,在第一通信设备获取到满足与第二通信设备进行多流数据传输的第一天线端口后,第一通信设备可以通知第二通信设备进入直射径多流传输模式,并根据所确定的第一天线端口向第二通信设备传输多流数据。
图9为本发明提供的数据传输的方法实施例三的流程示意图。本实施例涉及的是第二通信设备在根据第二通信设备的位置信息确定第一天线端口后,向第一通信设备上报携带第一天线端口相关参数的天线端口信息。在上述实施例的基础上,上述S101具体包括:
S301:第一通信设备接收所述第二通信设备根据所述第二通信设备的位置信息上报的天线端口信息;所述天线端口信息包括所述第一天线端口的数量和/或所述第一天线端口的序号。
具体的,第一通信设备接收所述第二通信设备根据第二通信设备的位置信息上报的天线端口信息可以有以下三种可能的实施方式:
第一种可能的实施方式:若第一通信设备和第二通信设备上均预设有所述第二通信设备的位置信息与所述第一天线端口的映射关系,或者,所述第二通信设备上预设有所述第二通信设备的位置信息与所述第一天线端口的映射关系(即第一通信设备上此时并没有预设的映射关系),则所述天线端口信息为所述第二通信设备根据所述第二通信设备的位置信息和所述映射关系 确定的。
具体的,与上述图7所示的实施例不同的是,本实施例是第二通信设备在获取到第二通信设备的位置信息后,根据第二通信设备的位置信息与所述第一天线端口的映射关系确定满足与第一通信设备进行多流数据传输的第一天线端口,并将第一天线端口的数量和/或所述第一天线端口的序号携带在天线端口信息中发送给第一通信设备。
第二种可能的实施方式:第一通信设备根据所述第二通信设备的位置信息向所述第二通信设备发送参考信号;所述参考信号用于指示所述第二通信设备根据所述参考信号获取信道状态信息,并根据所述信道状态信息选择所述第一天线端口;第一通信设备接收所述第二通信设备上报的所述天线端口信息。
具体的,第一通信设备可以根据第二通信设备的位置信息向第二通信设备发送参考信号,且不同位置下的第二通信设备根据所接收到的参考信号是不同的,因此,不同位置下的第二通信设备根据所获取的参考信号确定的信道状态信息也是不同的。该信道状态信息可以用Hrt来表示,即该信道状态信息用来表征接收端(第二通信设备)和发射端(第一通信设备)之间的信道状态,且该信道状态信息中还包括接收端(第二通信设备)上的天线端口的数量,故,第二通信设备就可以根据该信道状态信息中的发射端和接收端的信道状态、接收端的天线端口数量,在第一通信设备所提供的天线面板上选择第一天线端口。例如,假设第一通信设备上具有32个天线端口,第一通信设备根据所获取的第二通信设备的位置信息确定采用其中的16个天线端口向第二通信设备发送参考信号(参考信号的数量为16个,每个天线端口对应一个参考信号),可选的,第一通信设备可以将32个天线端口两两合并,得到16个天线端口组,一个天线端口组即可以看作是一个可用天线端口,用来发送参考信号。之后,第二通信设备接收到这16个参考信号之后,进行解调得到16个天线端口对应的信道状态信息,然后第二通信设备根据16个天线端口对应的信道状态信息选择符合与自己进行多流传输的天线端口(不同位置信息的第二通信设备所解调出来的信道状态信息是不同的),例如,假设第二通信设备支持8流传输,则第二通信设备就选择信道状态信息的秩为8的天线端口,或者,若上述16个天线端口对应的信道状态信息的秩小于8, 则根据实际最大的信道的秩从这16个天线端口中选择满足多流(流数为实际最大信道秩)传输所对应的天线端口作为第一天线端口。需要说明的是,第一通信设备上发射参考信号的天线端口的数量应该大于等于第二通信设备选择的第一天线端口。
又例如,若第二通信设备上只有两个天线,则第二通信设备可以根据上述信道状态信息选择第一通信设备上的其中两根发射端天线,保证两流数据的传输;若第二通信设备上有4根天线,为了支持4流传输,第二通信设备可以在第一通信设备上根据上述信道状态信息选择第一通信设备上的其中4根发射天线,从而保证四流的直射径传输,一般的,第二通信设备在第一通信设备提供的天线面板上选择时,可以参见图10所示,在天线面板的对角线上成对选择或者在垂直方向上成对选择或者在水平方向上成对选择至少两个天线端口。又或者,还可以采用天线组的方式选择,例如两流的数据传输,第一通信设备可以预定义两个天线配成一组,例如天线面板上对角线上最远的天线配成一组,或者垂直向某一列的两根天线配成一组,或者水平向某一行的天线配成一组,然后第二通信设备可以在所有的天线组中根据上述信道状态信息选择第一通信设备上的两个天线组。
可选的,第一通信设备也可以无需根据第二通信设备的位置信息向第二通信设备发送参考信号,即第一通信设备采用第一通信设备上的所有天线端口向第二通信设备发送参考信号,然后第二通信设备在接收到这些参考信号后,对其进行解调得到相应的信道状态信息,并根据这些信道状态信息选择符合与自己进行多流传输的天线端口。
之后,第二通信设备将所选择的第一天先端口的数量和/或第一天线端口的序号携带在天线端口信息中发送给第一通信设备。
第三种可能的实施方式:所述天线端口信息为所述第二通信设备根据所述第二通信设备的位置信息和所述第二通信设备上的第二天线端口的间距确定的。
具体的,由于在直射径条件下,实现多流传输需要满足传输距离D与发射天线间距dt以及接收天线间距dr之间具有固定的关系,因此,第二通信设备可以根据第二通信设备的位置信息中的视距传播距离(即前述的传输距离D)和角度信息,以及第二通信设备上已知的天线端口的间距dr,确定满 足与第二通信设备进行多流数据传输的天线端口应满足的天线间距dt;然后第二通信设备就可以在第一通信设备所提供的天线面板上选择满足该dt的第一天线端口。
S302:第一通信设备根据所述天线端口信息确定所述第一天线端口。
可选的,在第一通信设备根据上述第二通信设备上报的天线端口信息确定满足与第二通信设备进行多流数据传输的第一天线端口后,第一通信设备可以通知第二通信设备进入直射径多流传输模式,并根据所确定的第一天线端口向第二通信设备传输多流数据。
本发明实施例提供的数据传输的方法,第一通信设备获取所述第二通信设备根据所述第二通信设备的位置信息选择的第一天线端口,并根据所述第一天线端口与所述第二通信设备进行多流数据传输。本发明实施例提供的方法,可以支持基站与移动的用户设备间的多流数据传输,提高了视距传播下的多流数据传输系统的适用性。
图11为本发明提供的数据传输的方法实施例四的流程示意图。该方法的执行主体可以为上述图3或图5所示的数据传输设备,该数据传输设备为第二通信设备,其结构可以参见图3或图5所示,其可以执行下述实施例中的方法步骤。本实施例涉及的是第二通信设备根据第二通信设备的位置信息选择第一天线端口,并根据第一天线端口与第二通信设备进行多流数据传输的具体过程。如图11所示,该方法包括:
S401:第二通信设备根据所述第二通信设备的位置信息选择与所述第二通信设备的位置信息对应的第一天线端口;所述第一天线端口为所述第一通信设备上的满足与所述第二通信设备进行多流数据传输条件的天线端口;所述第二通信设备的位置信息包括所述第一通信设备和所述第二通信设备之间的视距传输距离,和/或,所述第一通信设备相对于所述第二通信设备的角度信息。
本实施例中,第一通信设备可以看作是发射端设备,则第一通信设备上所选择的用于发射的相邻的天线端口(发射天线)之间的间距即为dt,第二通信设备可以看作是接收端设备,第二通信设备上所选择的用于接收的相邻的天线端口(接收天线)之间的间距即为dr(可以参见图1所示)。由于第 二通信设备是可移动的用户设备,因此,第二通信设备与第一通信设备之间的传输距离(可以简称为D)是不固定的。可选的,当dr固定时,离第一通信设备不同距离D的第二通信设备所要求的第一通信设备上的发射天线之间的间距dt是不同的;当dt固定时,离第一通信设备不同传输距离的第二通信设备所要求的自身的接收天线之间的间距dr也是不同的(这是因为在直射径条件下,实现多流传输需要满足传输距离D与发射天线间距dt以及接收天线间距dr之间具有固定的关系)。本发明实施例以dr固定,第一通信设备获取与不同传输距离D下的第二通信设备进行通信的第一天线端口为例来进行说明。可选的,本发明实施例中可以有一个第一天线端口,也可以有多个第一天线端口。
具体的,第一通信设备和第二通信设备上均包括多个天线端口,可选的,第一通信设备可以向与自身具有不同传输距离的第二通信设备提供天线间距与之匹配的天线端口,故第二通信设备在确定自身的位置信息后,可以根据位置信息从第一通信设备上选择满足与自身进行多流数据传输的第一天线端口;可选的,第一通信设备还可以对自身天线面板上的天线进行分组,不同分组内的天线端口的间距不同,且不同分组内的天线端口可以对应不同传输距离下的第二通信设备,故第二通信设备在确定自身的位置信息后,可以根据位置信息从第一通信设备提供的天线组中选择满足与自身进行多流数据传输的天线组,作为第一天线端口;可选的,第一通信设备还可以仅向第二通信设备提供包括多个天线端口的天线面板,通过第一通信设备和第二通信设备之间的信令交互确定不同传输距离下的第二通信设备所对应的天线间距适配的天线端口。
需要说明的是,上述第二通信设备的位置信息可以包括第一通信设备和第二通信设备之间的视距传输距离(即上述的传输距离D),和/或,所述第一通信设备和所述第二通信设备的角度信息。可选的,该视距传输距离可以为第一设备的天线面板的中心与第二设备的天线面板的中心的连线距离或者水平线的距离(即上述的传输距离D),也可以为第一设备上高度最小的天线与第二设备上高度最小天线之间的连线的距离;可选的,该角度信息在实际应用中,可以为第二通信设备的天线与第一通信设备上对应的天线之间的到达角或离开角或与水平方向的夹角,还可以为第二通信设备的天线与第一 通信设备上对应的天线在X平面上的夹角或Y平面上的夹角或Z平面上的夹角,还可以为第一设备的天线下倾角或所述第二设备的天线倾角。该第二通信设备的位置信息可以是第一通信设备或第二通信设备通过测量相应的参考信号获取,也可以是通过GPS等定位信息获得,本发明实施例对第二通信设备的位置信息的获取方式并不做限定。
S402:第二通信设备根据所述第一天线端口与所述第一通信设备进行多流传输。
在本发明实施例中,第二通信设备获取的第一通信设备上的第一天线端口是与移动的第二通信设备的位置信息相关的,即若第二通信设备移动到某一位置时,第二通信设备所确定的第一天线端口的天线间距是与该位置的第二通信设备进行多流数据传输时适配的天线间距,故本发明实施例可以支持基站与移动的用户设备间的多流数据传输,提高了视距传播下的多流数据传输系统的适用性。
本发明实施例提供的数据传输的方法,第二通信设备根据第二通信设备的位置信息在第一通信设备上选择第一天线端口,并根据所述第一天线端口与所述第一通信设备进行多流数据传输。本发明实施例提供的方法,可以支持基站与移动的用户设备间的多流数据传输,提高了视距传播下的多流数据传输系统的适用性。
作为本发明实施例的一种可能的实施方式,本实施例涉及的是第一通信设备和第二通信设备上均预设有所述第二通信设备的位置信息与所述第一天线端口的映射关系时,第二通信设备获取第一天线端口的具体过程。在上述图11所示实施例的基础上,上述S401具体包括:第二通信设备根据所述第二通信设备的位置信息、所述第二通信设备的位置信息与所述第一天线端口的映射关系选择所述第一天线端口。
具体的,由于第二通信设备上预设有第二通信设备的位置信息与第一天线端口之间的映射关系,因此第二通信设备可以根据所确定的第二通信设备的位置信息确定满足与第一通信设备进行多流数据传输的第一天线端口。与此同时,第一通信设备也可以根据第二通信设备的位置信息和上述映射关系确定第二通信设备所选择的第一天线端口,从而使得该位置信息下的第二通 信设备可以根据上述第一天线端口与第一通信设备进行多流数据传输。
第一通信设备根据第二通信设备的位置信息和上述映射关系确定第二通信设备所选择的第一天线端口,具体可以为:
可选的,第一通信设备可以主动获取第二通信设备的位置信息,即第一通信设备可以通过测量相应的参考信号获取第二通信设备的位置信息,例如第一通信设备可以通过测量参考信号的信号接收强度或信干噪比等参数来获取第二通信设备的位置信息,然后根据所述第二通信设备的位置信息和所述映射关系获取所述第一天线端口。
可选的,第一通信设备还可以被动的获取第二通信设备的位置信息,即在上述S401之前,第二通信设备可以将第二通信设备的位置信息上报给第一通信设备,以使第一通信设备根据所述第二通信设备的位置信息和所述映射关系获取所述第一天线端口。可以参见上述图8所举的例子,本实施例在此不再赘述。
可选的,第一通信设备还可以直接获取第二通信设备所选择的第一天线端口,即在上述S401之后,第二通信设备还可以向所述第一通信设备发送天线端口信息;其中,该天线端口信息包括所述第一天线端口的数量和/或所述第一天线端口的序号;所述天线端口信息用于指示所述第一通信设备确定所述第一天线端口,故第一通信设备就可以根据该天线端口信息获知第二通信设备所选择的第一天线端口。在这种情况下,第一通信设备上可以预设有第二通信设备的位置信息与所述第一天线端口的映射关系,也可以不预设有第二通信设备的位置信息与所述第一天线端口的映射关系。
可选的,上述映射关系可以是在预先通过软件加载给第一通信设备上的处理器的,也可以是通过其他的网元(例如核心网网元、移动管理实体等)将映射关系发送给第二通信设备的。
图12为本发明提供的数据传输的方法实施例五的流程示意图。本实施例涉及的是第二通信设备根据第二通信设备的位置信息确定第一天线端口的另一具体过程。在上述图11所示实施例的基础上,上述S401具体包括:
S501:第二通信设备接收所述第一通信设备根据所述第二通信设备的位置信息下发的参考信号。
S502:第二通信设备根据所述参考信号确定信道状态信息。
具体的,第一通信设备可以根据第二通信设备的位置信息向第二通信设备发送参考信号,且不同位置下的第二通信设备根据所接收到的参考信号是不同的,因此,不同位置下的第二通信设备根据所获取的参考信号确定的信道状态信息也是不同的。
S503:第二通信设备根据所述信道状态信息选择所述第一天线端口。
具体的,上述信道状态信息可以用Hrt来表示,即该信道状态信息用来表征接收端(第二通信设备)和发射端(第一通信设备)之间的信道状态,且该信道状态信息中还包括接收端(第二通信设备)上的天线端口的数量,故,第二通信设备就可以根据该信道状态信息中的发射端和接收端的信道状态、接收端的天线端口数量,在第一通信设备所提供的天线面板上选择第一天线端口。例如,假设第一通信设备上具有32个天线端口,第一通信设备根据所获取的第二通信设备的位置信息确定采用其中的16个天线端口向第二通信设备发送参考信号(参考信号的数量为16个,每个天线端口对应一个参考信号),可选的,第一通信设备可以将32个天线端口两两合并,得到16个天线端口组,一个天线端口组即可以看做一个可用天线端口,用来发送参考信号。之后,第二通信设备接收到这16个参考信号之后,进行解调得到16个天线端口对应的信道状态信息,然后第二通信设备根据16个天线端口对应的信道状态信息选择符合与自己进行多流传输的天线端口,例如,假设第二通信设备支持8流传输,则第二通信设备就选择信道状态信息的秩为8的天线端口,或者,若上述16个天线端口对应的信道状态信息的秩小于8,则根据实际最大的信道的秩从这16个天线端口中选择满足多流(流数为实际最大信道秩)传输所对应的天线端口作为第一天线端口。需要说明的是,第一通信设备上发射参考信号的天线端口的数量应该大于等于第二通信设备选择的第一天线端口。
又例如,若第二通信设备上只有两个天线,则第二通信设备可以根据上述信道状态信息选择第一通信设备上的其中两根发射端天线,保证两流数据的传输;若第二通信设备上有4根天线,为了支持4流传输,第二通信设备可以根据上述信道状态信息在第一通信设备上选择其中4根发射天线,从而保证四流的直射径传输。一般的,第二通信设备在第一通信设备提供的天线 面板上选择时,可以参见上述图10所示,在天线面板的对角线上成对选择或者在垂直方向上成对选择或者在水平方向上成对选择至少两个天线端口。又或者,还可以采用天线组的方式选择,例如两流的数据传输,第一通信设备可以预定义两个天线配成一组,例如天线面板上对角线上最远的天线配成一组,或者垂直向某一列的两根天线配成一组,或者水平向某一行的天线配成一组,然后第二通信设备可以在所有的天线组中根据上述信道状态信息选择第一通信设备上的两个天线组。
可选的,第一通信设备也可以无需根据第二通信设备的位置信息向第二通信设备发送参考信号,即第一通信设备采用第一通信设备上的所有天线端口向第二通信设备发送参考信号,然后第二通信设备在接收到这些参考信号后,对其进行解调得到相应的信道状态信息,并根据这些信道状态信息选择符合与自己进行多流传输的天线端口。
S504:第二通信设备向所述第一通信设备发送天线端口信息;其中,所述天线端口信息包括所述第一天线端口的数量和/或所述第一天线端口的序号;所述天线端口信息用于使所述第一通信设备确定所述第一天线端口。
可选的,第一通信设备根据上述第二通信设备上报的天线端口信息确定满足与第二通信设备进行多流数据传输的第一天线端口后,可以通知第二通信设备进入直射径多流传输模式,并根据所确定的第一天线端口向第二通信设备传输多流数据。

S601:第二通信设备根据所述第二通信设备的位置信息和所述第二通信设备上的天线端口的间距,确定第一间距;其中,所述第一间距为所述第一通信设备与第二通信设备能够进行多流传输的所述第一通信设备上的天线端口应满足的间距。
具体的,由于在直射径条件下,实现多流传输需要满足传输距离D与发射天线间距dt以及接收天线间距dr之间具有固定的关系,因此,第二通信设备可以根据第二通信设备的位置信息中的视距传播距离(即前述的传输距 离D)和角度信息,以及第二通信设备上已知的天线端口的间距dr,确定第一间距dt,该第一间距为第一通信设备与第二通信设备能够进行多流传输的所述第一通信设备上的天线端口应满足的间距。
S602:第二通信设备根据所述第一间距,在所述第一通信设备的天线端口中选择满足所述第一间距的所述第一天线端口。

具体的,第一通信设备可以根据上述第二通信设备上报的天线端口信息,从所述第一通信设备的天线端口(或者天线面板)中确定满足与第二通信设备进行多流数据传输的第一天线端口。可选的,第一通信设备确定满足与第二通信设备进行多流数据传输的第一天线端口后,可以通知第二通信设备进入直射径多流传输模式,并根据所确定的第一天线端口向第二通信传输多流数据。
