相关申请的交叉引用
本申请主张在2018年6月22日在中国提交的中国专利申请No.201810651975.9的优先权，其全部内容通过引用包含于此。
技术领域
本公开涉及通信技术领域，尤其涉及一种波束测量方法、网络侧设备、终端设备及存储介质。
背景技术
无线频谱资源由国家统一分配使用，无线频谱分为两个部分：授权频段(licensed frequency band，LFB)和非授权频段(unlicensed frequency band，UFB)。在未来通信系统中，UFB可以作为LFB的补充帮助运营商对服务进行扩容。
目前，在LFB中使用波束进行数据传输，在使用波束进行数据传输之前需要进行波束测量。若在UFB中使用波束进行数据传输，则在使用波束进行数据传输之前也需要进行波束测量。可以利用现有的LFB中的波束测量方式对UFB进行波束测量。但是UFB中的数据传输机制与LFB中的数据传输机制不同，UFB多采用对话前监听/先听后发(listen before talk，LBT)机制。若利用现有的LFB中的波束测量方式对UFB进行波束测量，会增加在波束测量之前的LBT次数，增大系统开销。
发明内容
本公开实施例提供一种波束测量方法、网络侧设备、终端设备及存储介质，解决在波束测量之前的LBT次数多以及系统开销大的问题。

具体实施方式
下面将详细描述本公开的各个方面的特征和示例性实施例，为了使本公开的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本公开进行进一步详细描述。应理解，此处所描述的具体实施例仅被配置为解释本公开，并不被配置为限定本公开。对于本领域技术人员来说，本公开可以在不需要这些具体细节中的一些细节的情况下实施。下面对实施例的描述仅仅是为了通过示出本公开的示例来提供对本公开更好的理解。
需要说明的是，在本文中，诸如第一和第二等之类的关系术语仅仅用来将一个实体或者操作与另一个实体或操作区分开来，而不一定要求或者暗示这些实体或操作之间存在任何这种实际的关系或者顺序。而且，术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含，从而使得包括一系列要素的过程、方法、物品或者设备不仅包括那些要素，而且还包括没有明确列出的其他要素，或者是还包括为这种过程、方法、物品或者设备所固有的 要素。在没有更多限制的情况下，由语句“包括……”限定的要素，并不排除在包括所述要素的过程、方法、物品或者设备中还存在另外的相同要素。
目前，在LFB中使用波束进行数据传输，在使用波束进行数据传输之前需要进行波束测量。若在UFB中使用波束进行数据传输，则在使用波束进行数据传输之前也需要进行波束测量。可以利用现有的LFB中的波束测量方式对UFB进行波束测量。但是UFB中的数据传输机制与LFB中的数据传输机制不同，UFB多采用LBT机制。若利用现有的LFB中的波束测量方式对UFB进行波束测量，会增加在波束测量之前的LBT次数，增大系统开销。基于此，本公开实施例提供一种波束测量方法、网络侧设备、终端设备及存储介质，来减少在波束测量之前的LBT次数以及减少系统开销。下面首先对本公开实施例提供的波束测量方法进行介绍。
图1示出了本公开实施例的一种场景示意图。如图1所示，在网络侧设备A的信号覆盖范围内存在三个终端设备，分别为终端设备B1、终端设备B2与终端设备B3。网络侧设备A与每一个终端设备均能够进行上行通信和下行通信。本公开实施例提供的网络侧设备A可以为基站，该基站可以为通常所用的基站，也可以为演进型基站(evolved node base station，eNB)，还可以为第五代移动通信(5-th Generation,5G)系统中的网络侧设备(例如下一代基站(next generation node base station，gNB)或发送和接收点(transmission and reception point，TRP))或者小区(cell)等设备，或者后续演进通信系统中的网络侧设备。然用词并不构成对本公开保护范围的限制。在一些实施例中，终端设备可以为手机、平板电脑、智能手表、智能家电等，本公开实施例在此并不对其进行限定。
本公开实施例提供一种应用于网络侧设备的波束测量方法。如图2所示。图2示出了本公开实施例提供的应用于网络侧设备的波束测量方法的流程示意图。应用于网络侧设备的波束测量方法可以包括：步骤S201和S202。
S201：向终端设备发送配置信息。
该配置信息包括用于UFB的波束测量的CSI-RS资源的相关信息。
参考信号(Reference Signal，RS)，是由发射端提供给接收端用于信道估计或信道探测的一种已知信号。
上行RS包括：解调参考信号(DeModulation Reference Signal，DMRS)、探测参考信号(Sounding Reference Signal，SRS)。
下行RS包括：同步信号(Synchronization Signal，SS)、小区特定参考信号/公共参考信号(Cell-specific Reference Signals，CRS)、多播/组播单频网络参考信号(Multimedia Broadcast multicast service Single Frequency Network Reference Signals，MBSFN RS)、移动台特定参考信号(UE-specific RS)、定位参考信号(Positioning Reference Signal，PRS)和信道状态信息参考信号(Channel State Information-Reference Signal，CSI-RS)。
可以理解的是，在向终端设备发送包括用于UFB的波束测量的CSI-RS资源的相关信息的配置信息之前，需要对用于UFB的波束测量的CSI-RS资源的相关信息进行配置。在本公开的一些实施例中，可以利用无线资源控制(Radio Resource Control，RRC)信令对用于UFB的波束测量的CSI-RS资源的相关信息进行配置。
RRC对无线资源进行分配并发送相关信令，终端设备和网络侧设备之间控制信令的主要部分是RRC消息，RRC消息承载了建立、修改和释放MAC层和物理层协议实体所需的全部参数。
在本公开的一些实施例中，可以配置CSI-RS资源集中的每个CSI-RS资源具有至少一个时隙(slot)偏移(offset)。基于此，用于UFB的波束测量的CSI-RS资源的相关信息，可以包括：CSI-RS资源具有至少一个slot offset，其中，CSI-RS资源属于CSI-RS资源集。
可以理解的是，由于每个CSI-RS资源具有至少一个slot offset，使得CSI-RS资源可以在多个slot中发射。

在本公开的一些实施例中，可以将至少一个CSI-RS资源与SSB资源配置在同一个发现参考信号(Discovery Reference Signal，DRS)时隙内，DRS也可称为发现信号(Discovery Signal)。基于此，至少一个CSI-RS资源与一个SSB资源相关联，可以包括：至少一个CSI-RS资源与SSB资源在同一个DRS时隙内。
一个SSB资源对应四个符号，若SSB资源仅包括主同步信号(Primary Synchronization Signal，PSS)和辅同步信号(Secondary Synchronization Signal，SSS)，在本公开的一些实施例中，可以将至少一个CSI-RS资源配置在PSS或SSS所在符号的其他资源元素(Resource Element，RE)上。基于此，至少一个CSI-RS资源与一个SSB资源相关联，可以包括：至少一个CSI-RS资源位于PSS或SSS所在符号的其他RE上。
其中，RE指频域上的一个子载波及时域上的一个符号(symbol)。子载波又称为次载波，是正交频分复用技术(Orthogonal Frequency Division Multiplexing，OFDM)调制方式的多载波调制方式，这种方式将一个载波分为许多个带宽较窄的子载波，这些子载波相互正交，采用快速傅立叶变换对这些次载波信号进行编码。每个symbol都对应一个正交的子载波。
一个SSB资源对应四个符号，若SSB资源仅包括PSS和SSS，在本公开的一些实施例中，还可以将至少一个CSI-RS资源配置在SSB资源中原物理广播信道(Physical Broadcast Channel，PBCH)所在的RE上。基于此，至少一个CSI-RS资源与一个SSB资源相关联，可以包括：至少一个CSI-RS资源位于SSB资源中原PBCH所在的RE上。
一个SSB资源对应四个符号，若SSB资源仅包括PSS和SSS，在本公开的一些实施例中，还可以将至少一个CSI-RS资源配置在SSB资源中原PBCH 所在符号的其它RE上。基于此，至少一个CSI-RS资源与一个SSB资源相关联，可以包括：至少一个CSI-RS资源位于SSB资源中原PBCH所在符号的其它RE上。
在本公开的一些实施例中，还可以将至少一个CSI-RS资源配置在SSB资源所在符号的其他RE上。基于此，至少一个CSI-RS资源与一个SSB资源相关联，可以包括：至少一个CSI-RS资源位于SSB资源所在符号的其他RE上。

在本公开的一些实施例中，可以配置TRS资源与一个SSB资源位于同一符号上，还可以配置TRS资源与一个SSB资源相关联但TRS资源与SSB资源位于不同符号上。基于此，用于UFB的波束测量的CSI-RS资源的相关信息，还可以包括：TRS资源与一个SSB资源位于同一符号上，或，TRS资源与一个SSB资源相关联且TRS资源与SSB资源位于不同符号上。
在本公开的一些实施例中，配置信息中的子时间单元(sub-time unit)可以小于一个符号。其中，sub-time unit是用于测量一个发射波束和一个接收波 束形成的波束对链路质量的时间单位。当配置信息中的sub-time unit小于一个符号时，终端设备可以在一个符号内测量多个CSI-RS资源，从而提高了波束测量的速度。
S202：根据该配置信息，向终端设备发送CSI-RS资源，以使终端设备根据配置信息和CSI-RS资源对UFB进行波束测量。
在本公开的一些实施例中，根据该配置信息，向终端设备发送CSI-RS资源，可以包括：向终端设备发送SSB资源和与SSB资源相关联的CSI-RS资源。
在本公开的一些实施例中，至少一个CSI-RS资源和SSB资源使用同一个LBT测量结果且LBT测量结果为当前信道状态为空闲状态，网络侧设备可以发送SSB资源，然后可以发送与该SSB资源相关联的CSI-RS资源。基于此，向终端设备发送SSB资源和与SSB资源相关联的CSI-RS资源，可以包括：至少一个CSI-RS资源和SSB资源使用同一个LBT测量结果且LBT测量结果为当前信道状态为空闲状态，则向终端设备发送SSB资源和与SSB资源相关联的CSI-RS资源。
