本申请可以应用于长期演进(long term evolution,LTE)系统、新无线(new radio,NR)系统,或者,新无线车联网(NR vehicle to everything,NR V2X)系统;或者,多种接入技术(例如LTE和5G)混合组网的系统中;或者设备到设备(device-to-device,D2D)通信系统、机器到机器(machine to machine,M2M)通信系统、物联网(Internet of Things,IoT),或者,无人机通信系统;或者是支持多种无线技术例如支持LTE技术和NR技术的通信系统等;或者是非地面通信系统,例如:卫星通信系统、高空通信平台等。另外可选的,本申请可以也可以应用于窄带物联网(narrow band-internet of things,NB-IoT)系统、增强型数据速率全球移动通信(global system for mobile communications,GSM)演进系统(enhanced data rate for GSM evolution,EDGE)、宽带码分多址(wideband code division multiple access,WCDMA)系统、码分多址2000(code division multiple access,CDMA2000)系统、时分同步码分多址(time division-synchronization code division multiple access,TD-SCDMA)系统、应用面向未来的通信技术的系统,或者是其它的通信系统。
示例性的,该通信系统中包括网络设备和终端设备,网络设备作为配置信息发送实体,终端设备作为配置信息接收实体。具体来说,该通信系统中存在实体向另一实体发送配置信息,并向另一实体发送数据、或接收另一实体发送的数据;另一个实体接收配置信息,并根据配置信息向配置信息发送实体发送数据、或接收配置信息发送实体发送的数据。其中,本申请可应用于处于连接状态或激活状态(active)的终端设备、也可以应用于处于非连接状态(inactive)或空闲态(idle)的终端设备。
请参阅图1,为本申请实施例提供的一种应用场景的示意图。
如图1所示,配置信息发送实体可以为网络设备,配置信息接收实体可以为UE1-UE6。此时,基站和UE1-UE6组成一个通信系统。在该通信系统中,UE1-UE6可以发送上行数据给网络设备,网络设备接收UE1-UE6发送的上行数据。同时,网络设备可以向UE1-UE6发送配置信息。
在无线通信系统中,天线阵子指的是无线通信设备上用于接收信号和发射信号的装置,即天线阵子可以用于发射和接收电磁波。以图1所示通信系统为例,网络设备和终端设备一般都具备各自的天线阵子,用于收发信号。
随着多天线技术的普及,在网络设备中部署更多数量的天线阵子能够获得口径增益。示例性的,以网络设备为图2所示的节点B(Node B)为例,该网络设备的内部结构一般至少包括图2所示的基带和射频处理单元,以及多输入多输出(multiple input multiple output,MIMO)天线。其中,该MIMO天线可以包括2T/4T/8T/16T/32T等,“T”表示天线阵子,“2T”表示天线阵子数量为2,“4T”表示天线阵子数量为4,以此类推。传统的天线阵子数量为2T,而在MIMO系统中可以设置4T或以上。在基于波束的通信方式中,通过增加天线阵子数量的方式,能够形成更多的独立波束且能够使得波束的指向调整更灵活,在用户体验和小区容量上都能获得很大提升。
然而,在无线通信设备中,受限于天线的规格和尺寸,天线阵子数量较多的设备的通信性能不一定会持续优于天线阵子数量较少的设备的通信性能。示例性的,在偏视距(line of sight,LOS)的信道场景,各个波束间的隔离度更差,从而导致宽波束下的多流性能会比较差。即,在某些信道环境下(例如近点传输场景、偏LOS场景、多流传输场景等),天线阵子数量较多的设备的通信性能有可能比天线阵子数量较少的设备的通信性能差。
由上述内容可知,在天线阵子的数量增多的情况下有可能导致天线阵子之间的间距减小,进而导致不同天线阵子所发送的信号之间的干扰增大,影响通信性能。为此,如何提升通信性能,是一个亟待解决的技术问题。
为了解决上述问题,本申请提供了一种通信方法及装置,用于通过灵活设置发送信号的天线阵子数量的方式,优化所使用的天线阵子之间的间距,以期降低不同天线阵子所发送的信号之间的干扰,提升通信性能。下面将结合附图进一步介绍。
请参阅图3,为本申请提供的通信方法的一个示意图,该方法由网络设备执行,或者,该方法由网络设备中的部分组件(例如处理器、芯片或芯片系统等)执行,或者该方法还可以由能实现全部或部分网络设备功能的逻辑模块或软件实现。在下面的描述中,以该通信方法由网络设备为例进行描述。该方法包括如下步骤。
S301.网络设备获取第一信号的测量结果。
本公开中,网络设备具备至少M个天线阵子。该网络设备在步骤S301中获取第一信号的测量结果,该第一信号对应的天线阵子为M个天线阵子中的N个天线阵子,M和N为正整数,N小于M。
在一种可能的实现方式中,该网络设备在步骤S301中获取该第一信号的测量结果的过程包括:该网络设备发送该第一信号;该网络设备接收该第一信号的测量结果。具体地,该第一信号可以为该网络设备向终端设备所发送的下行信号。终端设备接收该第一信号之后,通过该终端设备对所接收的第一信号进行测量以得到测量结果。终端设备向网络设备发送该第一信号的测量结果,使得该网络设备获取该第一信号的测量结果。例如,第一信号的取值(例如序列值)是预配置的,网络设备以该(原始)取值向终端设备发送第一信号。终端设备根据第一信号的原始取值以及接收到的第一信号的取值,可以估计出接收值和发送值之间的差异,即可以估计出网络设备到终端设备之间的信道的测量结果。该方法中,第一信号对应的天线阵子为M个天线阵子中的N个天线阵子可以理解为:网络设备使用M个天线阵子中的N个天线阵子发送第一信号。
在另一种可能的实现方式中,该网络设备在步骤S301中获取该第一信号的测量结果的过程包括:该网络设备接收该第一信号;该网络设备基于该第一信号确定该第一信号的测量结果。具体地,该第一信号可以为终端设备向该网络设备所发送的上行信号。该网络设备在接收来自终端设备的第一信号之后,对所接收的第一信号进行测量并得到该第一信号的测量结果,获取该第一信号的测量结果。例如,第一信号的取值(例如序列值)是预配置的,终端设备以该(原始)取值向网络设备发送第一信号。网络设备根据第一信号的原始取值以及接收到的第一信号的取值,可以估计出接收值和发送值之间的差异,即可以估计出网络设备到终端设备之间的信道的测量结果。该方法中,第一信号对应的天线阵子为M个天线阵子中的N个天线阵子可以理解为:网络设备使用M个天线阵子中的N个天线阵子接收第一信号。
在一种可能的实现方式中,网络设备具备的M个天线阵子分别位于P列,第一信号对应的N个天线阵子分别位于该P列中的Q列,P和Q均为正整数,P小于或等于M,Q小于或等于N;其中,该Q列中的至少相邻两列在该P列中不相邻。具体地,网络设备所具备的至少M个天线阵子分别位于P列,用于发送第二信号的N个天线阵子分别位于P列中的Q列,且该Q列中的至少相邻两列在该P列中不相邻。即,用于发送第二信号的N个天线阵子中的至少一组相邻列的间距大于P列中的至少一组相邻列的间距,确保用于发送第二信号的N个天线阵子之间的间距得以增大,以降低不同天线阵子所发送的信号之间的干扰,提升通信性能。
可选地,M和N中的至少一个取值为2的整数倍。
可选地,M个天线阵子分别位于P列的实现中,M个天线阵子以均分的方式位于P列,或,M个天线阵子不以均分的方式位于P列,此处不做限定。其中,M个天线阵子以均分的方式位于P列的情况下,P列中的每一列所包含的天线阵子数量为M/P。类似地,N个天线阵子分别位于Q列的实现中,N个天线阵子以均分的方式位于Q列,或,N个天线阵子不以均分的方式位于Q列,此处不做限定。其中,N个天线阵子以均分的方式位于Q列的情况下,Q列中的每一列所包含的天线阵子数量为N/Q。
为便于理解,下面将通过几种示例,对M个天线阵子以均分的方式位于P列的实现过程,对N个天线阵子的实现方式进行示例性说明。
示例一,以M的取值为8、N的取值为4且P的取值为4为例,即8个天线阵子以均分的方式位于4列,每一列包含有两个天线阵子。即,8个天线阵子所在的4列可以表示为第一列(索引记为1)、第二列(索引记为2)、第三列(索引记为3)和第四列(索引记为4)。本公开中,索引可以从1开始标记,或者从0等其他数值开始标记,不予限制。例如上述第一列至第四列的索引还可以分别标记为0、1、2和3。
在示例一中,将P列中任意两列均相邻的列组合之外的其它列组合中的一种列组合作为N个天线阵子所在的Q列,其中,P列中任意两列均相邻的列组合为列索引包括(1,2)、(2,3)和(3,4),而除了该组合之外的其他列组合包括(1,3)、(1,4)和(2,4)。换言之,在示例一中,将该4列中不相邻的索引为(1,3)或(1,4)或(2,4)的列作为4个天线阵子所在的2(即Q的取值为2)列,以实现前述描述中,N个天线阵子所在的Q列中的至少相邻两列在P列中不相邻。
示例二,以M的取值为12、N的取值为4且P的取值为6为例,即12个天线阵子以均分的方式位于6列,每一列包含有两个天线阵子。即,12个天线阵子所在的6列可以表示为第一列(索引记为1)、第二列(索引记为2)、第三列(索引记为3)、第四列(索引记为4)、第五列(索引为5)和第六列(索引为6)。
在示例二中,将P列中任意两列均相邻的列组合之外的其它列组合中的一种列组合作为N个天线阵子所在的Q列,其中,P列中任意两列均相邻的列组合为列索引包括(1,2)、(2,3)、(3,4)、(4,5)和(5,6),而除了该组合之外的其他列组合包括(1,3)、(1,4)、(1,5)、(1,6)、(2,4)、(2,5)、(2,6)、(3,5)、(3,6)、(4,6)。换言之,在示例一中,将该6列中不相邻的索引为(1,3)或(1,4)或(1,5)或(1,6)或(2,4)或(2,5)或(2,6)或(3,5)或(3,6)或(4,6)的列作为4个天线阵子所在的2(即Q的取值为2)列,以实现前述描述中,N个天线阵子所在的Q列中的至少相邻两列在P列中不相邻。
示例性的,以上述示例一中M的取值为8且N的取值为4为例,即网络设备至少包括8T天线,第一信号对应的4T天线。如图4a所示,8T天线分别包括图中的4(即P的取值为4)列天线(即第一列、第二列、第三列和第四列),每一列天线通过图4a中的一个“交叉(即X)”表示,其中,每一列天线所包含的天线数量均为2。可选地,每个“交叉”可以表示在相同位置的不同极化方向的2个天线。并且,通过抽取边列的方式得到4T天线(即N的取值为4),且该4T天线分别位于2(即Q的取值为2)列(即第一列和第四列),以确保Q列天线中的至少两列不相邻。可以理解的是,除了图4a所示方式之外,还可以通过选取其它列的方式实现,例如在Q取值为2时,选取第一列和第三列作为Q列天线,或选取第二列和第四列作为Q列天线。在Q取值为3时,选取第一列、第二列和第四列作为Q列天线或选取第一列、第三列和第四列作为Q列天线。类似地,在M通过其它取值实现的情况下,也可以通过参考该实现方式选取N,此处不做赘述。
可选地,除了上述通过不同天线阵子有可能位于不同列的实现方式之外,不同天线阵子也有可能位于不同行,即M个天线阵子分别位于P行,该N个天线阵子分别位于该P行中的Q行,其中,该Q行中的至少相邻两行在该P行中不相邻。并且,P行和Q行的实现过程及有益效果可以参考上述P列和Q列的实现过程及有益效果,此处不做赘述。
在一种可能的实现方式中,该网络设备在步骤S401中获取该第一信号的测量结果的过程包括:在确定满足第一条件时,该网络设备在步骤S401中获取该第一信号的测量结果,该第一条件包括以下至少一项:该网络设备接收第一信息,且该网络设备确定该第一信息大于预设门限。例如该第一信息包括但不限于参考信号接收功率(reference signal received power,RSRP)、接收信号强度指示(received signal strength indicator,RSSI)、秩(RANK)、调制编码方案(modulation and coding scheme,MCS)、信道质量指示(channel quality indicator,CQI)中至少一项;或,该网络设备接收第二信息,且该网络设备确定该第二信息小于预设门限。例如该第二信息包括但不限于时延扩展信息。具体地,该网络设备可以在满足上述第一条件的情况下,该网络设备可以确定信道质量较差、处于多流通信场景、处于视距(line of sight)通信场景,或处于偏LOS通信场景(即近似于LOS通信 场景)等中的至少一项。这些有可能导致通信性能下降的情况出现时,该网络设备触发执行获取该第一信号的测量结果,以期通过减少用于发送信号的天线阵子数量的方式提升通信性能。此外,该第一条件可以通过上述多种方式实现,以提升方案的灵活性。

本公开中,网络设备确定在步骤S301中获取的第一信号的测量结果优于第一阈值时,该网络设备在步骤S302中基于N个天线阵子发送第二信号。
需要说明的是,在第一信号的测量结果对应的取值大小与该第一信号的测量结果所指示的性能优劣之间呈正相关的情况下,第一信号的测量结果对应的取值越大则该第一信号的测量结果所指示的性能越优,反之,第一信号的测量结果对应的取值越小则该第一信号的测量结果所指示的性能越劣,相应的,第一信号的测量结果优于第一阈值可以为第一信号的测量结果对应的取值大于第一阈值。此外,在第一信号的测量结果对应的取值大小与该第一信号的测量结果所指示的性能优劣之间呈负相关的情况下,第一信号的测量结果对应的取值越大则该第一信号的测量结果所指示的性能越劣,反之,第一信号的测量结果对应的取值越小则该第一信号的测量结果所指示的性能越优,相应的,第一信号的测量结果优于第一阈值可以为第一信号的测量结果对应的取值小于第一阈值。
可选地,N个天线阵子中的一个或多个天线阵子可以对应于一个虚拟天线端口(或称为天线端口,端口,虚拟天线等),为此,该网络设备基于该N个天线阵子发送第二信号的过程中,该网络设备可以在确定该N个天线阵子对应的虚拟天线端口之后,基于该N个天线阵子对应的虚拟天线端口对第二信号进行处理(例如预编码,加权等)以得到处理结果,并基于该N个天线阵子发送该处理结果。
可选地,该第二信号可以为包括下行信号,下行数据等。
在一种可能的实现方式中,该第一阈值为预配置;或,该第一阈值为第三信号的测量结果。其中,该第三信号对应的天线阵子为该M个天线阵子。具体地,该第一阈值可以为上述任一项所示方式实现,以提升方案实现的灵活性。其中,在该第一阈值为预配置的情况下,可以节省信令开销。而在该第一阈值为M个天线阵子所对应的第三信号的测量结果的情 况下,可以使得该网络设备基于实际传输的情况确定是否基于M个天线阵子中的部分天线阵子发送第二信号,以提升该方案执行的有效性。
应理解,与前述第一信号的实现过程类似,该第三信号可以为下行信号,也可以为上行信号,此处不再赘述。其中,第一信号和第三信号可以为相同传输方向的信号,例如都是上行信号或者都是下行信号,或者,可以为不同传输方向的信号,例如第一信号是下行信号且第三信号是上行信号,或者第一信号是上行信号且第三信号是下行信号,此处不予限制。第三信号的测量结果的实现定方式类似前述第一信号的测量结果的实现方式,此处不再赘述。
在一种可能的实现方式中,该方法还包括:在该第一信号的测量结果劣于第一阈值时,该网络设备基于该M个天线阵子发送第四信号。具体地,在该第一信号的测量结果劣于第一阈值时,则该网络设备可以确定基于N个天线阵子执行发送过程的性能较差,为此,该网络设备可以基于该M个天线阵子发送第四信号,以避免性能下降。
可选地,该第四信号可以为包括下行信号,下行数据等。
示例性的,此处仍以M的取值为8且N的取值为4为例,即网络设备至少包括8T天线,第一信号对应的4T天线。其中,如图4b所示,8T天线的传输方式相比于4T天线的传输方式天线间距较小,即4T天线间距更大,主瓣更窄,这就使得离散傅立叶变换(discrete Fourier transform,DFT)波束更宽,有可能在某些特定场景下(例如近点传输场景、偏LOS场景、多流传输场景等),8T天线的传输方式的性能比4T天线的传输方式的性能差。
换言之,基于上述示例,在某些特定场景(例如偏LOS场景)下,用户多径方向不会非常分散,4T大间距相比8T,相同角度范围内,可以容纳更多的正交波束,能使得同时接收到两个正交波束的信号都较强,秩(rank)3~4的性能更优。如图4c所示,图中不同弧形代表不同的几个正交波束,横坐标表示辐射角度的取值,纵坐标表示信号强度的取值。可以看到8T天线的波束更宽。在相同的角度扩展下,两个正交波束的信号强度差异较大,即在rank3~4的情况下8T天线的性能比4T天线的性能差。
如图4d所示,横坐标表示信号与干扰加噪声比(signal to interference plus noise ratio,SINR),纵坐标表示下行媒体接入控制层吞吐率(downlink MAC Throughput,DL MAC THUPT),相同DL MAC THUPT的情况下SINR的取值越小表示性能越好,反之,相同DL MAC THUPT的情况下SINR的取值越大表示性能越差。由图4d可以看出,在上述特殊场景下,大间距的4T的性能优于小间距的8T天线的性能。而除了上述特殊场景之外,非近点偏LOS场景,网络设备仍然使用8T天线进行信号传输,即在该第一信号的测量结果劣于第一阈值时,该网络设备基于该M个天线阵子发送第四信号。
可选的,在一种可能的实现方式中,在该第一信号的测量结果等于第一阈值时,该网络设备基于该N个天线阵子发送第四信号。具体地,在该第一信号的测量结果等于第一阈值时,该网络设备可以基于该N个天线阵子发送第四信号,以期在性能不变的情况下通过减少用于发送信号的天线阵子数量的方式,避免不必要的能耗增加。
可选的,在一种可能的实现方式中,在该第一信号的测量结果等于第一阈值时,该网络设备基于该M个天线阵子发送第四信号。具体地,在该第一信号的测量结果等于第一阈值时,该网络设备可以基于该M个天线阵子发送第四信号,以期简化实现。
基于上述技术方案,网络设备具备至少M个天线阵子,该网络设备在步骤S301中获取M个天线阵子中的N个天线阵子对应的第一信号的测量结果之后,在该第一信号的测量结果优于第一阈值时,该网络设备在步骤S302中基于该N个天线阵子发送第二信号。换言之,网络设备确定N个天线阵子对应的第一信号的测量结果较优(即优于第一阈值)时,该网络设备基于M个天线阵子中的部分天线阵子发送第二信号。从而,通过减少用于发送信号的天线阵子数量的方式,增大所使用的天线阵子之间的间距,以期降低不同天线阵子所发送的信号之间的干扰,提升通信性能。
作为一种实现示例,上述图3所示实现过程还可以通过图5所示方式实现。在图5所示实例中,以M的取值为8且N的取值为4,第一信号为CSI-RS,且第一阈值为8天线阵子的测量结果为例进行描述。
S501.收集第一条件相关的参数(例如RSSI/RANK/时延扩展等信息)。
S502.判断第一条件是否成立,即判断RSSI是否大于或等于门限值(即判断RSSI>=门限值),以及判断RANK是否大于或等于门限值(即判断RANK>=门限值)等中的至少一项判断过程,并在确定满足第一条件时,执行步骤S503,在确定不满足第一条件时,执行步骤S506。
S503.重配用户级CSI-RS 4端口(Port)非周期测量(此处假设CSI-RS 4Port对应于4个天线阵子),其中,CSI-RS 4Port即为前述示例中的第一信号。
S504.判断4天线阵子的测量结果是否优于8天线阵子的测量结果,若是,则执行步骤S505,若否,则执行步骤S506。其中,8天线阵子的测量结果即为前述实施例中的第三信号的测量结果。
S505.采用4天线阵子(即4T4Port)的映射方式发送信号(即前述实施例中的第二信号)。
S506.采用8天线阵子(即8T8Port)的映射方式发送信号(即前述实施例中的第四信号)。
应理解,图5所示的实现过程可以参考前述示例的描述,此处不做赘述。
在图5所述实现方式中,根据实际信道情况,通过测量自适应选择其中全部或部分天线阵子发射,从而使整体性能更优,并且,可以提升下行用户感知速率、提升下行系统容量。
