Description

波束信息更新的方法、终端设备和网络设备
本申请要求于2019年08月05日提交国家知识产权局、申请号为201910718385.8、申请名称为“波束信息更新的方法、终端设备和网络设备”的中国专利申请的优先权,其全部内容通过引用结合在本申请中。
技术领域
本公开涉及通信领域,尤其涉及一种波束信息更新的方法、终端设备和网络设备。
背景技术
随着终端设备对数据量需求的增加,为了满足日益增长的通信性能的需求,大规模天线和高频段通信相结合将成为趋势,其中高频段为6GHz以上的频段。
具体而言,高频段具有较为丰富的空闲频率资源,可以为数据传输提供更大的吞吐量。高频信号的波长短,与低频段相比,能够在同样大小的面板上布置更多的天线阵元,有助于利用波束赋形技术形成指向性更强、波瓣更窄的波束,并为数模混合波束赋形技术的应用提供了较高的实用前景。
对于高频通信而言,随着工作频段的增高,模拟波束的波瓣将更窄,波束的数量将增多,那么做波束训练时需要增加测量的时延以及增大参考信号(Reference Signal,RS)资源开销。但是,较窄的波束对于终端侧的移动或旋转会更加敏感,较小的位置变化即会使得网络侧与终端侧的收发波束无法对准,进而会引起通信质量的降低,如此会增加波束训练的频度。
其中,目前现有的波束训练是由网络侧控制的,包括周期性波束训练和非周期性波束训练,其中,非周期性波束训练为网络侧动态触发对小范围的波束进行测量以及波束优化,也就是说,不允许终端侧自主发起波束训练。而且,目前现有的波束训练,需要先使用信道状态信息参考信号(Channel State Information Reference Signal,CSI-RS)做下行的波束测量或使用探测参考信号(Sounding Reference Signal,SRS)做上行的波束测量,然后网络侧向终端侧指示各下行信道或上行信道的波束,这样耗时较长,不利于实现快速的波束调整以及数据传输。
发明内容
本公开实施例解决的技术问题之一为波束信息更新过程耗时较长,不利于实现快速的波束调整和数据传输。
第一方面,本公开实施例提供一种波束信息更新的方法,应用于终端设备,所述方法包括:

在本公开实施例中,当由终端设备确定的与波束信息更新相关的参数满足对应的预设条件时,终端设备可以主动触发用于进行波束测量的上行信息的发送,并进一步可以根据波束测量的结果,完成波束信息的更新。如此,无需网络设备的控制即可以由终端设备及时主动地触发进行波束测量,以使网络设备侧与终端设备侧的收、发波束能够及时对准,从而保证通信质量,同时可以降低波束测量的开销与时延,加快波束更新与数据传输的进程。

具体实施方式
下面将结合本公开实施例中的附图,对本公开实施例中的技术方案进行清楚、完 整地描述,显然,所描述的实施例是本公开一部分实施例,而不是全部的实施例。基于本公开中的实施例,本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例,都属于本公开保护的范围。
目前,长期演进(Long Term Evolution,LTE)、增强长期演进(Long Term Evolution Advanced,LTE-A)、第五代(5G)等移动通信系统均引入了相应的多输入多输出(Multiple-Input Multiple-Output,MIMO)技术和正交频分复用(Orthogonal Frequency Division Multiplexing,OFDM),以基于MIMO技术利用多天线系统所获得的空间自由度,来提高峰值速率和系统频谱利用率。
随着MIMO技术的维度不断扩展,在LTE Rel-8版本中,最多可以支持4层的MIMO传输,在Rel-9版本中的多用户MIMO(Multi User MIMO,MU-MIMO)传输中最多可以支持4个下行数据层,以及在Rel-10版本中,将单用户MIMO(Single User MIMO,SU-MIMO)的传输能力扩展至最多8个数据层。进一步地,正在将MIMO技术向着三维化和大规模化的方向推进。目前,第三代(3G)移动通信系统已经完成了三维信道建模的研究,并且正在开展全维度多重输入多重输出增强(Enhancements on Full-Dimension MIMO for LTE,eFD-MIMO)和NR(New Radio,新空口)MIMO的研究和标准化工作。可以预见,在未来的5G移动通信系统中,更大规模、更多天线端口的MIMO技术将被引入。
另外,大规模天线技术(Massive MIMO)使用大规模天线阵列,能够极大地提升系统频带利用效率,支持更大数量的接入用户,因此,大规模天线技术是下一代移动通信系统中最有潜力的物理层技术之一。在大规模天线技术中,如果采用全数字阵列,可以实现最大化的空间分辨率以及最优MU-MIMO性能,但是这种结构需要大量的模拟-数字信号转换(Analog to Digital Convert,AD)/数字-模拟信号转换(Digital to Analog Convert,DA)转换器件以及大量完整的射频-基带处理通道,无论是设备成本还是基带处理复杂度都将是巨大的负担。
为了避免上述的实现成本与设备复杂度,数模混合波束赋形技术应用而生,即在传统的数字域波束赋形基础上,在靠近天线系统的前端的射频信号上增加一级波束赋形。模拟赋形能够通过较为简单的方式,使发送信号与信道实现较为粗略的匹配。模拟赋形后形成的等效信道的维度小于实际的天线数量,因此其后所需的AD/DA转换器件、数字通道数以及相应的基带处理复杂度都可以大为降低。模拟赋形部分残余的干扰可以在数字域赋形部分再进行一次处理,从而保证MU-MIMO传输的质量。相对于全数字赋形而言,数模混合波束赋形是性能与复杂度的一种折中方案,在高频段大带宽或天线数量很大的系统中具有较高的实用前景。
对于高频段,在对第四代(4G)移动通信系统以后的下一代通信系统中,将通信系统支持的工作频段提升至6GHz以上的高频段,比如100GHz,高频段具有较为丰富的空闲频率资源,可以为数据传输提供更大的吞吐量。目前3GPP已经完成了高频信道建模工作,高频段信号的波长短,与低频段相比,能够在同样大小的天线集合上布置更多的天线阵元,从而可以利用波束赋形技术形成指向性更强、波瓣更窄的波束。因此,大规模天线和高频段通信相结合将成为趋势。
然而,随着工作频段的增高,比如50GHz以上的频段,模拟波束的波瓣将更窄, 波束的数量将增多,那么做波束训练时需要增加测量的时延以及增大参考信号RS资源开销。但是,较窄的波束对于终端设备的移动或旋转会更加敏感,较小的位置变化即会使得网络设备与终端设备的收发波束无法对准,进而会引起通信质量的降低,如此会增加波束训练的频度。
其中,目前现有的波束训练是由网络设备控制的,包括周期性波束训练和非周期性波束训练,其中,非周期性波束训练为网络设备动态触发对小范围的波束进行测量以及波束优化,也就是说,不允许终端设备自主发起波束训练。而且,目前现有的波束训练,需要先使用信道状态信息参考信号CSI-RS做下行的波束测量或使用探测参考信号SRS做上行的波束测量,然后网络设备向终端设备指示各下行信道或上行信道的波束,这样耗时较长,不利于实现快速的波束调整以及数据传输。
因此,亟需一种波束信息更新的方案,以缩减波束信息更新的耗时,实现快速的波束调整和数据传输,并进一步提高通信质量。
以下结合附图,详细说明本公开各实施例提供的技术方案。
参见图1所示,本公开实施例提供一种波束信息更新的方法,由终端设备执行,方法包括以下流程步骤:
步骤101:在终端设备的与波束信息更新相关的参数满足预设条件的情况下,发送上行信息,上行信息用于进行波束测量。
步骤103:根据波束测量的结果,更新波束信息。
在本公开实施例中,当由终端设备确定的与波束信息更新相关的参数满足对应的预设条件时,终端设备可以主动触发用于进行波束测量的上行信息的发送,并进一步可以根据波束测量的结果,完成波束信息的更新。如此,无需网络设备的控制即可以由终端设备及时主动地触发进行波束测量,以使网络设备侧与终端设备侧的收、发波束能够及时对准,从而保证通信质量,同时可以降低波束测量的开销与时延,加快波束更新与数据传输的进程。
进一步地,对于小数据包业务,比如网络游戏中的数据传输业务,在传输前也需要做波束测量,通过本公开实施例的方法,可以缩短波束测量的时长与传输小数据包所需的时长间的差距,利于实现快速的数据传输。
可选地,上述上行信息用于进行上行波束测量,或者用于进行下行波束测量。波束可以称为空间滤波器(Spatial Filter),空间域传输滤波器(Spatial Domain Transmission Filter)等。波束信息可以称为传输配置指示(Transmission Configuration Indication,TCI)状态信息、准共址(Quasi Co-Location,QCL)信息或空间关系(Spatial Relation)信息等。波束信息可以包括波束序号、波束对应的参考信号资源索引、或波束的质量信息等。
可选地,在本公开实施例的波束信息更新的方法中,可以通过如下具体实施中的一个确定与波束信息更新相关的参数是否满足其对应的预设条件。
在一个具体实施例中,在上述参数为终端设备的位置状态变化值的情况下,若位置状态变化值达到第一设定值,则确定参数满足预设条件。
可以理解,当终端设备的位置状态发生变化时,且在位置状态变化达到一定程度的情况下,可以确定与波束信息更新相关的参数满足相应的预设条件,则可以由终端 设备触发上行信息的及时发送,以进行相应的波束测量,从而快速地解决由终端设备的位置状态发生变化所引起的收、发波束无法对准的问题。
其中,上述终端设备的位置状态变化至少可以包括:终端设备移动、终端设备旋转、终端设备被遮挡等;具体可以通过终端设备本身具有的相应的传感器等器件感知终端设备的位置状态变化情况。
在另一个具体实施例中,在上述参数为终端设备对下行波束测量指标的测量结果的情况下,若下行波束测量指标的测量结果达到第二设定值,则确定参数满足预设条件。
其中,下行波束测量指标包括参考信号接收功率(Reference Signal Received Power,RSRP)、参考信号接收质量(Reference Signal Received Quality,RSRQ)和信号与干扰加噪声比(Signal-to-Noise and Interference Ratio,SINR)中的至少一项。
