在终端设备与网络设备基于天线的通信过程中,终端设备的有些波束质量高,有些波束质量差。通常在终端设备与网络设备基于天线进行数据传输之前,会进行波束训练,以选择质量较好的波束出来。
目前,已有针对终端设备具有一个天线面板的场景的波束训练的相关方案。但是,尚无针对终端设备具有多个天线面板的场景进行多个天线面板的训练和管理的方案。

图1为本申请应用的场景示意图。
如图1所示,网络设备与终端设备通过天线进行通信,即,终端设备与网络设备利用天线进行信号的接收与发送。终端设备和网络设备上都具有天线单元(antenna element)。
多个天线单元可以集成在一个面板(panel)上,这个集成了天线单元的面板称为天线面板(也可用panel表示)。
每个天线面板可产生一个或多个波束(beam)。波束是一种通信资源。波束可以是宽波束,或者窄波束,或者其他类型波束。形成波束的技术可以是波束成形技术或者其他技术手段。波束成形技术可以具体为数字波束成形技术,或者模拟波束成形技术,或者混合数字/模拟波束成形技术。不同的波束可以认为是不同的资源。通过不同的波束可以发送相同的信息或者不同的信息。可选地,可以将具有相同或者类似的通信特征的多个波束视为是一个波束。一个波束内可以包括一个或多个天线端口,用于传输数据信道,控制信道和探测信号等。波束分为发送波束和接收波束。例如,发送波束可以指信号经天线发射出去后在空间不同方向上形成的信号强度的分布;接收波束可以指从天线上接收到的无线信号在空间不同方向上的信号强度分布。应理解,形成一个波束的一个或多个天线端口也可以看作是一个天线端口集。波束在协议中的体现还可以是空域滤波器(spatial filter)。

网络设备上也可以具有多个天线面板(图1中未示出)。
如果终端设备利用某个天线面板的波束向网络设备发送上行信号,则该天线面板可以称为终端设备的发送天线面板,对应地,发送天线面板产生的波束称为发送波束。如果终端设备利用某个天线面板的波束接收网络设备的下行信号,则该天线面板可以称为终端设备的接收天线面板,对应地,接收天线面板产生的波束称为接收波束。
终端设备的发送天线面板与接收天线面板可以是同一个天线面板,也可以是不同的天线面板。

为了便于描述与理解,本文以天线面板为例进行描述。本文中描述的天线面板均可替换为射频链路。

本申请实施例通过网络设备为终端设备配置参考信号资源集合,使得终端设备可以根据该参考信号资源集合,对终端设备的天线面板进行训练,从而实现对终端设备具有的多个天线面板进行管理。
可选地,本文中提及的波束也可以称为空域传输滤波器,发送波束也可以称为空域发射滤波器,接收波束也可以称为空域接收滤波器。
用于指示传输信号所使用的波束的信息可以称为波束指示信息。波束指示信息包括波束编号、波束管理资源编号、上行信号资源号、下行信号资源号、波束的绝对索引、波束的相对索引、波束的逻辑索引、波束对应的天线端口的索引、波束对应的天线端口组索引、波束对应的下行信号的索引、波束对应的下行同步信号块的时间索引、波束对连接(beam pair link,BPL)信息、波束对应的发送参数(Tx parameter)、波束对应的接收参数(Rx parameter)、波束对应的发送权重、波束对应的权重矩阵、波束对应的权重向量、波束对应的接收权重、波束对应的发送权重的索引、波束对应的权重矩阵的索引、波束对应的权重向量的索引、波束对应的接收权重的索引、波束对应的接收码本、波束对应的发送码本、波束对应的接收码本的索引、波束对应的发送码本的索引中的至少一种。其中,下行信号包括同步信号、广播信道、广播信号解调信号、信道状态信息下行信号(channel state information reference signal,CSI-RS)、小区专用参考信号(cell specific reference signal,CS-RS)、UE专用参考信号(user equipment specific reference signal,US-RS)、下行控制信道解调参考信号,下行数据信道解调参考信号,下行相位噪声跟踪信号中任意一种。上行信号包括中上行随机接入序列,上行探测参考信号(SRS),上行控制信道解调参考信号,上行数据信道解调参考信号,上行相位噪声跟踪信号任意一种。
波束指示信息还可以体现为传输配置编号(transmission configuration index,TCI),TCI中可以包括多种参数,例如,小区编号,带宽部分编号,参考信号标识,同步信号块标识,准同位(quasi-co-location,QCL)类型等。
可选地,网络设备还可以为频率资源组关联的波束中具有准同位(quasi-co-location,QCL)关系的波束分配QCL标示符。
QCL关系用于表示多个资源之间具有一个或多个相同或者相类似的通信特征。对于具有QCL关系的多个资源,可以采用相同或者类似的通信配置。例如,如果两个天线端口具有QCL关系,那么一个端口传送一个符号的信道大尺度特性可以从另一个端口传送一个符号的信道大尺度特性推断出来。大尺度特性可以包括:延迟扩展,平均延迟,多普勒扩展,多普勒频移,平均增益,接收参数,终端设备接收波束编号,发射/接收信道相关性,接收到达角,接收机天线的空间相关性,主到达角(angel-of-arrival,AoA),平均到达角,主到达角的扩展等。
QCL还包括空域准同位(spatial QCL)。spatial QCL可以认为是QCL的一种类型。对于空域准同位,可以分别从发送端和接收端两个角度理解。从发送端来看,如果两个天线端口是空域准同位的,表示这两个天线端口的对应的波束方向在空间上是一致的。从接收端来看,如果两个天线端口是空域准同位的,表示这个接收端能够在相同的波束方向上接收到这两个天线端口发送的信号。
关于QCL,还存在准同位假设(QCL assumption)的概念。准同位假设是指假设两个端口之间是否具有QCL关系。准同位假设的配置和指示可以用来帮助接收端进行信号的接收和解调。例如接收端能确认A端口和B端口具有QCL关系,即可以将A端口上测得的信号的大尺度参数用于B端口上的信号测量和解调。
可选地,用于训练天线面板的参考信号资源集合也可称为天线面板管理资源或波束管理资源。
波束管理资源,指的是用于波束管理的资源,又可以体现为用于计算和测量波束质量的资源。波束质量包括层一接收参考信号功率(layer 1 reference signal received power,L1-RSRP),层一接收参考信号质量(layer 1 reference signal received quality,L1-RSRQ)等。
例如,波束管理资源可以包括同步信号(synchronization signal,SS),物理广播信道(physical broadcast channel,PBCH),下行信道测量参考信号,跟踪信号,下行控制信道解调参考信号,下行共享信道解调参考信号,上行探测参考信号,上行随机接入信号等。
网络设备为终端设备配置的参考信号资源集合中包括一个或多个参考信号的资源集合,其中,一个参考信号的资源集合用于终端设备的一个天线面板的训练。
网络设备可以根据终端设备具有的天线面板的数量,确定参考信号资源集合中包括的参考信号的资源集合的数量。例如,参考信号资源集合中包括的参考信号的资源集合的数量等于、或大于、或小于终端设备具有的天线面板的数量。
可选地,网络设备确定的配置信息中还包括第一触发信息,该第一触发信息用于激活参考信号资源集合中各个参考信号的资源集合。
终端设备根据第一触发信息,可以获知什么时候发送SRS,也可以获知什么时候开始天线面板的训练。
以参考信号为SRS为例。假设网络设备为终端设备生成的配置信息包括:
a)一个或多个SRS的资源集合(SRS resource set),每个资源集合中有一个或多个SRS资源(对应于参考信号资源集合)。
b)用于触发一个或多个SRS的资源集合的第一触发信息。
例如,为非周期的传输设计触发(trigger),一次触发可以激活一个或多个SRS资源集合的传输。每个SRS的资源集合均设置有自己的偏移量(offset)。
可选的,一次触发可以激活一个或多个SRS资源集合中的一个或多个SRS资源的传输。每个SRS资源均设置有自己的偏移量。
对于每个SRS的资源集合的具体配置,可以使用现有技术实现,本文不作详述。
可选地,网络设备为终端设备确定的配置信息中还包括训练模式信息,该训练模式信息用于指示该终端设备训练天线面板的模式。
该终端设备训练天线面板的模式包括如下至少一种:单天线面板模式,多天线面板模式,或指定天线面板模式。
第一种情形,该终端设备的天线面板的训练模式为单天线面板模式。
步骤230,终端设备通过该参考信号的资源集合,对该终端设备具有的天线面板进行训练,包括:终端设备通过参考信号资源集合中的资源,对该终端设备当前使用的天线面板进行训练。
终端设备当前使用的天线面板表示如下中的任一种:终端设备当前处于上电(power-on)状态的天线面板、终端设备最近一次上行传输的天线面板、终端设备最近一次下行传输的接收天线面板对应的发送天线面板、终端设备接收控制信道的接收天线面板对应的发送天线面板。
如图3所示,假设终端设备具备4个天线面板,且终端设备当前使用的天线面板为天线面板1,则终端设备使用天线面板1产生的波束(例如图3中所示的两个波束)与网络设备进行信号的接收与发送。
例如,还可从图3看出,终端设备在资源#1上使用当前使用的天线面板的波束1传输参考信号,终端设备在资源#2上使用当前使用的天线面板的波束2传输参考信号,这里的资源#1和#2为网络设备配置的参考信号资源集合中的资源。
下文描述终端设备在单天线面板模式下,如何进行发送天线面板和接收天线面板的训练。
1)发送天线面板的训练。
假设网络设备为终端设备配置的参考信号资源集合中包括上行参考信号的资源集合,例如,SRS的资源集合。
步骤230包括如下步骤:终端设备通过上行参考信号的资源集合中的资源,采用终端设备当前使用的天线面板,向网络设备发送上行参考信号;网络设备根据接收的上行参考信号,从终端设备当前使用的天线面板包括的波束中选择出终端设备的最佳发送波束。
网络设备可以根据波束质量,从终端设备当前使用的天线面板包括的波束中选择出终端设备的最佳发送波束。
本文提及的波束质量包括层一接收参考信号功率(layer 1 reference signal received power,L1-RSRP),层一接收参考信号质量(layer 1 reference signal received quality,L1-RSRQ)等。
本申请中不限制衡量波束质量的度量指标,可能的指标包括参考信号接收功率(reference signal received power,RSRP),块误码率(block error rate,BLER),参考信号接收质量(reference signal received quality,RSRQ),参考信号接收强度指示(received signal strength indicator,RSSI),信号干扰噪声比(signal to interference and noise ratio,SINR),信号质量指示(channel quality indicator,CQI)相关性等。
根据波束质量,从多个波束中选择最佳波束的过程是现有技术,本文不作详述。
可选地,最佳发送波束可以是一个波束也是可以多个波束。
2)接收天线面板的训练。
假设网络设备为终端设备配置的参考信号资源集合中包括下行参考信号的资源集合,例如,CSI-RS的资源集合。
步骤230包括如下步骤:终端设备通过该下行参考信号的资源集合中的资源,采用终端设备当前使用的天线面板,接收网络设备下发的下行参考信号;终端设备根据接收的下行参考信号,从当前使用的天线面板包括的波束中选择出最佳接收波束。
终端设备可以根据波束质量,从当前使用的天线面板包括的波束中选择出最佳接收波束。
可选地,最佳接收波束可以是一个波束也是可以多个波束。
在本申请实施例中,通过网络设备为终端设备配置单天线面板模式,使得终端设备仅对于当前使用的天线面板进行训练。
单天线面板模式适用于,在终端设备的发送天线面板或接收天线面板已确定的情况下,网络设备指示终端设备在一个较小的范围内寻找最优的发送波束或接收波束的场景。
第二种情形:该终端设备的天线面板的训练模式为多天线面板模式。
步骤230,该终端设备通过该参考信号的资源集合,对该终端设备具有的天线面板进行训练,包括:终端设备通过该参考信号资源集合中的资源,对该终端设备具有的所有天线面板进行训练。
如图4所示,假设终端设备具有4个天线面板,则终端设备分别使用这4个天线面板与网络设备进行通信,以训练这4个天线面板。
例如,还可从图4看出,终端设备在资源集合#1的各个资源上分别使用天线面板1上的波束,在资源集合#2的各个资源上分别使用天线面板2上的波束,在资源集合#3的各个资源上使用天线面板3上的波束,在资源集合#4的各个资源上使用天线面板4上的波束。其中,资源集合#1、资源集合#2、资源集合#3和资源集合#4为网络资源为终端设备配置的参考信号资源集合中包括的资源。
下文描述终端设备在多天线面板模式下,如何进行发送天线面板和接收天线面板的训练。
1)发送天线面板的训练。
假设网络设备为终端设备配置的参考信号资源集合中包括上行参考信号的资源集合,例如,SRS的资源集合,且参考信号资源集合中包括的上行参考信号的资源集合的数量不小于终端设备具有的天线面板的数量。
步骤230包括如下步骤:终端设备通过上行参考信号的资源集合中的资源,采用终端设备具有的所有天线面板,向网络设备发送上行参考信号;网络设备根据接收的上行参考信号,从终端设备具有的所有天线面板中选择出终端设备的最佳发送天线面板。
网络设备可以根据波束质量,从终端设备具有的所有天线面板中选择出终端设备的最佳发送天线面板。
从多个天线面板中选择最佳天线面板的原理,与根据波束质量从多个波束中选择最佳波束的原理类似,例如,将包括的波束质量的综合指标最佳的天线面板确定为最佳天线面板。根据波束质量从多个波束中选择最佳波束的过程是现有技术,本文不作详述。
可选地,可以综合考虑多个天线面板中每个天线面板各自包括的多个波束的波束质量,例如以这多个波束的波束质量的平均值或者滤波之后的值作为指标,从多个天线面板中选择最佳天线面板。
可选地,最佳发送天线面板可以是一个天线面板也可以是数量少于终端设备具有的所有的天线天面的数量的多个天线面板。
在本申请实施例中,网络设备通过控制终端设备的发送天线面板的训练,可以有效地获取终端设备的最佳发送天线面板的相关信息。在后续通信中,网络设备可以指示终端设备仅使用最佳发送天线面板进行上行通信,在保证通信质量的同时,也可以降低终端设备的功耗。
2)接收天线面板的训练。
假设网络设备为终端设备配置的参考信号资源集合中包括下行参考信号的资源集合,例如,CSI-RS的资源集合,且参考信号资源集合中包括的上行参考信号的资源集合的数量不小于终端设备具有的天线面板的数量。
步骤230包括如下步骤:终端设备通过下行参考信号的资源集合中的资源,采用终端设备具有的所有天线面板,接收网络设备下发的下行参考信号;终端设备根据接收的下行参考信号,从终端设备具有的所有天线面板中选择出最佳接收天线面板。
终端设备可以根据波束质量,从终端设备具有的所有天线面板中选择出最佳接收天线面板。
可选地,最佳接收天线面板可以是一个天线面板也可以是数量少于终端设备具有的所 有的天线天面的数量的多个天线面板。
在多天线面板模式下,终端设备按照一定的顺序使用各个天线面板(具体是各个天线面板上产生的波束)。
可选地,终端设备按照各个天线面板的编号和资源集合的编号从大到小或者从小到大的顺序依次对应,然后终端设备根据这个对应关系,在对应的资源集合上顺序使用各个天线面板。
可选地,网络设备向终端设备下发的配置信息中还包括参考信号资源集合中各个资源集合与终端设备具有的天线面板之间一对一的对应关系,则终端设备根据这个对应关系,在对应的资源集合上顺序使用各个天线面板。
在多天线面板模式下,在终端设备的发送天线训练场景中,该方法200还包括:该网络设备确定该终端设备的不同天线面板发送上行参考信号的时间间隔,并且在配置参考信号资源集合时,通过设计资源使得该终端设备的不同天线面板发送上行参考信号的时间间隔大于该终端设备切换不同天线面板所需的时间。进一步地,该网络设备向该终端设备发送该终端设备的不同天线面板发送该上行参考信号的时间间隔。
应理解,当网络设备配置的终端设备的不同天线面板发送该上行参考信号的时间间隔小于终端设备切换不同天线面板所需的时间时,终端设备无法实现发送天线面板的切换。
在多天线面板模式下,在终端设备的接收天线训练场景中,该方法200还包括:该网络设备确定该终端设备的不同天线面板接收上行参考信号的时间间隔,并且在配置参考信号资源集合时,通过设计资源使得该终端设备的不同天线面板接收上行参考信号的时间间隔大于该终端设备切换不同天线面板所需的时间。进一步地,该网络设备向该终端设备发送该终端设备的不同天线面板接收该上行参考信号的时间间隔。
应理解,当网络设备配置的终端设备的不同天线面板接收下行参考信号的时间间隔小于终端设备切换不同天线面板所需的时间时,终端设备无法实现接收天线面板的切换。
在本申请实施例中,通过网络设备为终端设备配置多天线面板模式,使得终端设备可以对其具有的所有天线面板进行训练。
多天线面板模式适用于在终端设备的多个天线面板中选择最优天线面板的场景。例如终端设备刚接入网络之后尚未对其所有天线面板进行训练,这时,需要采用多天线面板模式进行终端设备的天线面板进行训练。
第三种情形:该终端设备的天线面板的训练模式为指定天线面板模式。
指定天线面板模式指的是,由网络设备指定终端设备具有的天线面板中哪些天线面板要进行训练。
步骤230包括:该终端设备通过该参考信号的资源集合中的资源,对该终端设备具有的由该网络设备指定的一个或多个天线面板进行训练。
在指定天线面板模式下,网络设备需要向终端设备通知指定的天线面板。网络设备可以通过多种方式向终端设备通知指定的天线面板。
可选地,作为一种方式,网络设备向终端设备下发的配置信息中还包括天线面板指示信息,该天线面板指示信息指示终端设备的一个或多个天线面板,或者,一个或多个天线面板分组,由该天线面板指示信息所指示的天线面板就是网络设备指定的要进行训练的天线面板。
可选地,网络设备可以通过单独的下行信令向终端设备下发该天线面板指示信息。
可选地,作为另一种方式,网络设备配置的参考信号资源集合中的每个参考信号的资源集合均配置有一个天线面板的指示信息。
换言之,网络设备利用所配置的参考信号资源集合间接地指定终端设备的要进行训练的一个或多个天线面板。
例如,终端设备具有天线面板1-4,网络设备为终端设备配置的参考信号资源集合包括资源集合#1和资源集合#2,其中,资源集合#1配置有天线面板1的指示信息,资源集合#2配置有天线面板2的指示信息。则终端设备根据网络设备配置的参考信号资源集合,可以获知要进行训练的天线面板为天线面板1和2。
下文描述终端设备在指定天线面板模式下,如何进行发送天线面板和接收天线面板的训练。
1)发送天线面板的训练。
假设网络设备为终端设备配置的参考信号资源集合中包括上行参考信号的资源集合,例如,SRS的资源集合,且参考信号资源集合中包括的上行参考信号的资源集合的数量不小于网络设备指定训练的天线面板的数量。
步骤230包括如下步骤:终端设备通过上行参考信号的资源集合中的资源,采用网络设备指定的一个或多个天线面板,向网络设备发送上行参考信号;网络设备根据接收的上行参考信号,从网络设备指定的一个或多个天线面板中选择出终端设备的最佳发送天线面板。
网络设备可以根据波束质量,从网络设备指定的一个或多个天线面板中选择出终端设备的最佳发送天线面板。
可选地,最佳发送天线面板可以是一个天线面板也可以是数量少于网络设备指定的一个或多个天线面板的数量的多个天线面板。
在本申请实施例中,网络设备通过控制终端设备的发送天线面板的训练,可以有效地获取终端设备的最佳发送天线面板的相关信息。在后续通信中,网络设备可以指示终端设备仅使用最佳发送天线面板进行上行通信,在保证通信质量的同时,也可以降低终端设备的功耗。
2)接收天线面板的训练。
假设网络设备为终端设备配置的参考信号资源集合中包括下行参考信号的资源集合,例如,CSI-RS的资源集合,且参考信号资源集合中包括的上行参考信号的资源集合的数量不小于网络设备指定的天线面板的数量。
步骤230包括如下步骤:终端设备通过该下行参考信号的资源集合中的资源,采用网络设备指定的天线面板,接收网络设备下发的下行参考信号;终端设备根据接收的下行参考信号,从网络设备指定的一个或多个天线面板中选择出最佳接收天线面板。
终端设备可以根据波束质量,从网络设备指定的一个或多个天线面板中选择出最佳接收天线面板。
可选地,最佳接收天线面板可以是一个天线面板也可以是数量少于网络设备指定的一个或多个天线面板的数量的多个天线面板。
在指定天线面板模式下,如果网络设备指定的天线面板为多个,则终端设备按照一定的时序,顺序使用各个指定的天线面板(具体是各个天线面板上产生的波束)。
在网络设备通过向终端设备下发天线面板指示信息来通知终端设备哪些天线面板要 进行训练的情况下,终端设备按照指定的天线面板的编号和资源集合的编号从大到小或者从小到大的顺序依次对应,然后终端设备根据这个对应关系,在对应的资源集合上顺序使用各个指定的天线面板。
在网络设备通过所配置的参考信号资源集合间接地指定终端设备的要进行训练的天线面板的情况下,终端设备可以直接根据资源集合与指定的天线面板之间的对应关系,确定使用各个指定天线面板的时序。
在指定天线面板模式下,如果网络设备指定的天线面板为多个,网络设备还需配置在不同天线面板上发送参考信号的时间间隔或在不同天线面板上接收参考信号的时间间隔大于终端设备切换不同天线面板的时间间隔。进一步地,该网络设备向该终端设备发送在不同天线面板发送上行参考信号或在不同天线面板上接收下行参考信号的时间间隔。
在本申请实施例中,通过网络设备为终端设备配置指定天线面板模式,使得终端设备仅对网络设备指定的天线面板进行训练。
在本申请提供的方案中,通过网络设备为终端设备配置多种训练天线面板的模式,可以使终端设备在不同场景下,采用较为合适的训练模式对其天线面板进行训练,从而可以对终端设备具有的多个天线面板实现灵活多变的训练和管理。
上文描述了网络设备为终端设备配置了三种训练天线面板的训练模式,但本申请并非限定于此,实际应用中,可以根据具体需求设计更多种其它的训练模式,这些方案也落入本申请的保护范围。
对于训练模式信息,网络设备可以通过显式方式或隐式方式向终端设备指示。
可选地,网络设备向终端设备发送下行信令,该下行信令中包括“天线面板训练模式”字段,该“天线面板训练模式”字段上携带上述的三种训练模式信息中的任一种。
可选地,网络设备通过配置的参考信号资源集合间接向终端设备指示训练模式信息。
当网络设备配置的参考信号资源集合中只包括一个参考信号的资源集合时,表示训练模式为单天线面板模式。例如,网络设备仅配置一个SRS资源集合和/或一个CSI-RS资源集合时,表示训练模式为单天线面板模式。
当网络设备配置的参考信号资源集合中包括的参考信号的资源集合的数量与终端设备具有的天线面板的数量相等时,表示训练模式为多天线面板模式。例如,网络设备配置的SRS资源集合的数量和/或CSI-RS资源集合的数量与终端设备具有的天线面板的数量相等时,表示训练模式为多天线面板模式。
当网络设备配置的参考信号资源集合中的每个参考信号的资源集合均配置有天线面板指示信息时,表示训练模式为指定天线面板模式。
在上文描述的实施例中,终端设备基于网络设备配置的上行参考信号的资源集合对终端设备的发送天线面板进行训练,基于下行参考信号的资源集合对终端设备的接收天线面板进行训练。本申请还提出联合下行参考信号的资源集合与上行参考信号的资源集合,对终端设备的发送天线面板进行训练,以及联合下行参考信号的资源集合与上行参考信号的资源集合,对终端设备的接收天线面板进行训练。
可选地,在一些实施例中,网络设备为终端设备配置的参考信号资源集合中包括上行参考信号的资源集合和下行参考信号的资源集合,网络设备向终端设备下发的配置信息中还包括第二触发信息,该第二触发信息用于指示该下行参考信号的资源集合和该上行参考信号的资源集合之间的绑定关系,和/或用于通知该终端设备时间差,该时间差表示终端 设备从接收下行参考信号中的最后一个符号到发送上行参考信号中的第一个符号之间的时间间隔,或者,该时间差表示终端设备从发送上行参考信号中的最后一个符号到接收下行参考信号中的第一个符号之间的时间间隔。
例如,网络设备确定的配置信息中包括如下信息a)、b)和c)。
a)一个或多个SRS资源集合,每个SRS资源集合中包括一个或多个SRS资源(对应于上行参考信号的资源集合)。
b)一个或多个CSI-RS资源集合,每个CSI-RS资源集合中包括一个或多个CSI-RS资源(对应于下行参考信号的资源集合)。
c)SRS资源集合与CSI-RS资源集合之间的关联关系,该关联关系包括SRS资源集合与CSI-RS资源集合的联合触发,即哪些SRS资源集合与哪些CSI-RS资源集合绑定在一起实现天线面板的训练,该关联关系还包括绑定的同组SRS资源集合与CSI-RS资源集合之间的时间差,即终端设备接收到CSI-RS中的最后一个符号之后需要等多长时间开始发送SRS中的第一个符号(对应于第二触发信息)。这里提及的符号可以是正交频分复用(orthogonal frequency division multiplexing,OFDM)符号或时隙符号。
下文描述如何联合网络设备配置的上行参考信号的资源集合和下行参考信号的资源集合,训练终端设备的发送天线面板与接收天线面板。
可选地,在本实施例中,在步骤230中,终端设备联合网络设备配置的上行参考信号的资源集合和下行参考信号的资源集合,训练终端设备的发送天线面板。具体地,步骤230包括如图5所示的训练终端设备的发送天线面板的步骤。
510,网络设备利用下行参考信号的资源集合中的资源向该终端设备发送下行参考信号。
如图6所示,终端设备具有4个天线面板,网络设备为该终端设备配置CSI-RS资源集合(即下行参考信号的资源集合)与SRS资源集合(即上行参考信号资源集合)。网络设备通过CSI-RS资源集合向终端设备发送CSI-RS。
520,终端设备通过接收的下行参考信号,获取该终端设备的最佳天线面板。
还以图6为例,终端设备通过CSI-RS资源集合利用4个天线面板接收网络设备发送的CSI-RS。例如,根据接收的各个CSI-RS的质量,从4个天线面板中选择最佳天线面板,在图6中,最佳天线面板为天线面板4。
530,终端设备通过上行参考信号的资源集合中的资源采用该最佳天线面板,向网络设备发送上行参考信号。
具体地,终端设备从网络设备配置的第二触发信息中,获知终端设备从接收下行参考信号中的最后一个符号到发送上行参考信号中的第一个符号之间的时间间隔(记为时间间隔T1)。终端设备在完成下行参考信号的接收后,等待时间间隔T1之后,开始向网络设备发送上行参考信号。
还以图6为例,终端设备通过SRS资源集合,利用最佳天线面板,即天线面板4向网络设备发送SRS。
540,网络设备通过接收的上行参考信号,从终端设备的最佳天线面板的波束中选择最佳波束。
还以图6为例,网络设备接收终端设备接收的SRS。例如根据接收的各个SRS的质量,网络设备从最佳天线面板,即天线面板4的波束中选择最佳波束。
应理解,上述的步骤510至步骤520对应于上文描述的多天线面板模式,步骤530和步骤540对应于上文描述的单天线面板模式。
网络设备可以指示终端设备在后续上行通信中,使用最佳天线面板或最佳波束。
可选地,在本实施例中,在步骤230中,终端设备联合网络设备配置的上行参考信号的资源集合和下行参考信号的资源集合,训练终端设备的接收天线面板。
具体地,步骤230包括如下训练终端设备的接收天线面板的步骤:终端设备利用上行参考信号的资源集合中的资源向网络设备发送上行参考信号;网络设备通过接收的上行参考信号,获取该终端设备的最佳天线面板;网络设备通过下行参考信号的资源集合中的资源使用该最佳天线面板中的波束,向终端设备发送下行参考信号;终端设备通过接收的下行参考信号,从终端设备的最佳天线面板的波束中选择最佳波束。
其中,终端设备接收网络设备发送的下行参考信号,包括:终端设备从网络设备配置的第二触发信息中,获知终端设备从发送上行参考信号中的最后一个符号到接收下行参考信号中的第一个符号之间的时间间隔(记为时间间隔T2);终端设备在完成上行参考信号的发送后,等待时间间隔T2之后,开始接收向网络设备发送的下行参考信号。
终端设备还可以向网络设备上报确定的最佳波束,以便于网络设备在后续下行通信中使用该最佳波束,从而使得终端设备能够使用这个最佳波束接收信号。
在本申请实施例中,联合利用上行参考信号与下行参考信号对终端设备的发送天线面板进行训练,不仅可以选择出最佳发送天线,还可以选择出最佳发送波束,在保证通信质量的同时,还可以降低终端设备的功耗。
上文描述了基于网络设备配置的上行参考信号的资源集合训练终端设备的发送天线面板,基于网络设备配置的下行参考信号的资源集合训练终端设备的接收天线面板,联合网络设备配置的上行参考信号的资源集合和下行参考信号的资源集合训练终端设备的发送天线面板(或者发送波束),联合网络设备配置的上行参考信号的资源集合和下行参考信号的资源集合训练终端设备的接收天线面板(或者接收波束)。
在具有波束一致性的情况下,下行波束训练的波束对(网络设备发,终端设备收)也可以用于上行传输(终端设备发,网络设备收)。波束一致性指收发通道的方向性可控制在一定误差范围内。也就是说,射频通道在发送模式朝向某个方向发送信号,那么当其处于接收模式时,也能从相同的方向接收信号。因此,在具有波束一致性的情况下,只需训练终端设备的接收天线面板或发送天线面板,无需对二者都训练。
为了让网络设备获知终端设备具有的天线面板的相关能力,并可以基于这种能力,更好地为终端设备配置用于天线面板训练的参考信号资源集合,终端设备还可以向网络设备上报自己的天线面板相关能力。
可选地,在一些实施例中,方法200还包括:终端设备向网络设备发送天线面板能力信息,该天线面板能力信息用于指示终端设备具有的天线面板的相关能力。该天线面板能力信息用于指示如下能力中至少一种。
能力一,该终端设备具有的天线面板的数量,该终端设备具有的天线面板的数量包括该终端设备具有的发送天线面板的数量,和/或该终端设备具有的接收天线面板的数量。
例如,终端设备具有的天线面板的数量为:{1-8}。{1-8}表示1至8中任一个整数。例如,终端设备具有的天线面板的数量为:{4},表示终端设备具有4个天线面板。
再例如,终端设备具有的发送天线面板的数量为:{1-8};和/或终端设备具有的接收 天线面板的数量为:{1-8}。
能力二,该终端设备能够同时使用的接收天线面板或发送天线面板的数量。

能力五,该终端设备的发送天线面板分组的数量,和/或每个发送天线面板分组中包括的发送天线面板的数量和/或标识。
例如,终端设备的发送天线面板共分为2组,每组中包括2个发送天线面板,发送天线面板#1和#2为组1,发送天线面板#3和#4为组2。
能力六,该终端设备切换接收天线面板的如下至少一种能力:该终端设备切换接收天线面板的时间间隔,该终端设备在预设时间段内切换接收天线面板的次数。
例如,终端设备切换接收天线面板的时间间隔为14或28个OFDM符号时间(symbol duration),或者为1或2个时隙(slot),或者为0.25或0.5毫秒(ms)等。
再例如,终端设备在一个时隙内最多切换接收天线面板的次数为2、4、7或14。

例如,终端设备切换发送天线面板的时间间隔为14或28个OFDM符号时间(symbol duration),或者为1或2个时隙(slot),或者为0.25或0.5毫秒(ms)等。
再例如,终端设备在一个时隙内最多切换发送天线面板的次数为7或14。

在本申请实施例中,通过终端设备向网络设备上报天线面板相关能力,使得网络设备能准确的获得关于终端设备侧天线面板的信息,从而有利于网络设备对终端设备的多个天线面板的管理。例如,配置多少资源给终端设备进行天线面板管理和波束管理。再例如,如何配置用于训练天线面板/波束的各个资源之间的时间间隔等。
网络设备根据终端设备上报的天线面板相关能力,可以获知终端设备最佳的发送天线面板信息,进而保证上行传输的性能。此外,网络设备可以指示终端设备使用最佳天线面板进行上行传输,相比于现有技术中终端设备总是开启多个天线面板,本申请的方案可以有效降低终端设备的功耗。
具体地,在终端设备向网络设备上报自己的天线面板相关能力时,可以通过显式方式上报,也可以通过隐式方式上报。
可选地,终端设备向网络设备发送的天线面板能力信息直接表示上述能力一至能力九中至少一种能力。
可选地,终端设备向网络设备发送的天线面板能力信息中包括用于间接指示上述能力一至能力九中至少一种能力的间接指示信息。例如,间接指示信息包括上下行参考信号资源(resource),资源集合(resource set),资源设置(resource setting)或分组(group)等相关的信息。

例如,波束分组指的是,终端设备按自己的接收能力将网络设备的发送波束进行分组。例如终端设备可以将其能在同一天线面板接收到的多个网络设备的发送波束分为一组,这时,分组数量即为终端设备的接收天线面板的数量。
再例如,波束分组指的是,终端设备将自己的发送波束进行分组。例如终端设备可以将其能在同一天线面板发送的多个发送波束分为一组,这时,分组数量即为终端设备的发送天线面板的数量。
终端设备具有的上行参考信号的资源集合的数量,例如为,SRS资源集合(SRS resource set)数量。
可选地,终端设备的SRS资源集合的数量可以是用于天线面板管理的SRS资源集合的数量。例如,定义SRS Set Use=panel management。
可选地,终端设备的SRS资源集合的数量可以是用于波束管理的SRS资源集合的数量。例如,定义SRS Set Use=beam management。
应理解,通过设计终端设备具有的上行参考信号的资源集合的数量来表示终端设备具有的发送天线面板的数量,可以实现,终端设备使用相同的天线面板发送同一个上行参考信号的资源集合内的一个或多个上行参考信号。还应理解,在终端设备的上、下行传输对称的情况下,终端设备具有的上行参考信号的资源集合的数量还可以表示终端设备具有的接收天线面板的数量。
终端设备具有的下行参考信号的资源集合的数量,例如为,CSI-RS资源集合(CSI-RS resource set)的数量。
可选地,终端设备的CSI-RS资源集合的数量可以是用于天线面板管理的CSI-RS资源集合的数量。例如,定义CSI-RS Set Use=panel management。

例如,该终端设备的每个下行参考信号的资源集合中包括的资源的数量,为终端设备的每个SRS资源集合中的SRS资源的数量。
再例如,该终端设备的每个上行参考信号的资源集合中包括的资源的数量,为终端设备的每个CSI-RS资源集合中的CSI-RS资源的数量。
在本申请实施例中,网络设备根据终端设备上报的天线面板相关能力,可以获知终端设备最佳的发送天线面板信息,进而保证上行传输的性能。此外,网络设备可以指示终端设备使用最佳天线面板进行上行传输,相比于现有技术中终端设备总是开启多个天线面板,本申请的方案可以有效降低终端设备的功耗。
在本申请实施例中,通过终端设备向网络设备上报该终端设备的天线面板相关能力,可以使得网络设备基于终端设备的能力为终端设备配置合理的网络配置,例如不应超出终端设备的天线面板相关能力。
例如,网络设备获取到终端设备的天线面板相关能力后,对终端设备进行合理的网络配置,使其不超出终端设备的能力。
换句话说,终端设备的天线面板相关能力的上报可以看作是终端设备向网络设备请求资源的方式。
例如,当终端设备上报其具有4个发送天线面板,网络设备应该为其配置4个SRS资源集合(SRS resource set),以便终端设备进行上行天线面板的训练。
又例如,当终端设备上报每个天线面板可以打出8个波束,网络设备配置的每个用于天线面板训练的SRS资源集合(SRS resource set)可以有8个SRS资源(SRS resource)。
可选地,网络设备可以发起终端设备能力请求,终端设备收到该请求后向网络设备上报自己的天线面板相关能力。
可选地,终端设备的天线面板相关能力发生变化时,可以触发请求,进而将更新的天线面板相关能力上报给网络设备。
应理解,如果网络配置不合理,终端设备可以根据自己具有的天线面板相关能力(及上文描述的能力一至能力九)规范终端设备在不合理配置下的行为,以免终端设备产生混乱。
例如,当网络设备配置的一个时隙内终端设备切换天线面板的次数(例如5次)超过了终端设备上报的切换能力(例如4次),则终端设备可以放弃超出能力的天线面板切换(即不进行第五次切换)。
当终端设备的接收天线面板数和发送天线面板数不匹配时,可以引入天线面板对(panel pair)的概念,即将一个接收天线面板和一个或多个发送天线面板绑定为一个对(pair),或者将一个发送天线面板和一个或多个天线面板绑定为一个天线面板。
一个天线面板对(panel pair)中包含哪些接收天线面板和发送天线面板可以由网络设备通知终端设备,也可以由终端设备通知网络设备。
本申请实施例还提供一种天线面板管理的方法,该方法包括:终端设备向网络设备发送天线面板能力信息,该天线面板能力信息用于指示终端设备具有的天线面板的相关能力;网络设备向终端设备发送配置信息,该配置信息包括参考信号资源集合的信息,该参考信号资源集合用于终端设备的天线面板的训练。
