具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本公开相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本公开的一些方面相一致的装置和方法的例子。
相关技术中，终端基于蜂窝网络与无线接入设备、核心网设备等无线网络设备进行通信，可以实现定位测量功能。例如，在NR Rel-16中，主要讨论了针对连接态(connected)下的终端的定位测量，定义了用于定位的参考信号。用于定位的参考信号例如可以包括用于下行定位的PRS、用于上行定位的SRS。而定位测量包括终端测量和无线网络设备测量，测量值包括信号强度测量值，信号传输时间值以及信道到达或出发的角度值。
相关技术中，LOS径的测量值能够有效提高定位精度，故在进行信号强度值、时间值或是角度值测量时，要达到最高定位精度，进行LOS径的测量有一定的必要性。但事实上，LOS径不一定都有。最早到达的路径最接近LOS径或者就是LOS。故，在Rel-16的定位讨论中，希望尽量能确定出first arrival path，即最早到达的路径，也称为第一到达径。
相关技术中，为了确定出第一到达径，需要发送大量的定位用途参考信号，比如以下行为例，基站需要使用各个发送波束(Tx beam)发送定位参考信号，而对于每个基站Tx beam发送的定位参考信号，终端需要使用自己的每个接收波束(Rx beam)都接收一下Tx beam发送的定位参考信息，以便最终获得第一到达径。故，最坏的情况下对应进行第一到达径确定需要测量的参考信号数目是基站的Tx beam数与终端的Rx beam数的乘积。而上行时，最坏的情况下，对应进行第一到达径确定需要测量的参考信号的数目是终端的Tx beam数与基站的Rx beam数的乘积。然而，需要测量的参考信号数目越多，终端越耗能，定位测量需要的时间越长，从而定位时延越大，定位精度越差。
为了减少获得第一到达径时终端的耗能，可以在前期进行波束管理(beam management)时，确定出第一到达径对应的Tx beam和Rx beam，进而使得在做测量时，可以减少测量的参考信号数目。但是，Rel-16中beam management的测量中只包含对beam的信号强度的测量，信号强度包括层一的参考信号接收功率(Layer1-Reference Signal  Received Power，L1-RSRP)/层一的接收信号强度指示(Layer1-Received Signal Strength Indication，L1-RSSI)。测量上报的结果包含参考信号ID和L1-RSRP/L1-RSSI。
相关技术中，基于第一到达径信息(例如信号飞行时间)可以确定出第一到达径，然而已有beam management的测量和上报不包含各个path上信号的飞行时间，所以不能提前找出第一到达径，用于定位用途参考信号的发送，导致需要发送和测量大量的定位参考信号，才能找出第一到达径，从而增大终端功耗，延长定位测量时间，降低定位精度等问题。
有鉴于此，本公开实施例提供一种波束管理方法，在进行波束管理过程中进行参考信号测量并反馈的测量结果中包括参考信号对应波束的第一到达径信息，后续基于第一到达径信息确定第一到达径，便于尽快确定出第一到达径，减少终端功耗，也能减少定位时延并提高定位精度。
一示例中，第一到达径信息表征参考信号对应波束是否为第一到达径，或者第一到达径信息包括有参考信号的飞行时间信息。
又一示例中，进行波束管理过程中，进行参考信号测量时，不仅测量反馈参考信号的信号强度，还要测量反馈参考信号的飞行时间。从而基站可以根据信号强度和飞行时间，来配置用于定位测量的参考信号，比如尽量配置飞行时间较短的定位参考信号。从而使得终端在进行定位测量时能尽快找到第一到达径，减少终端的能耗，同时也能减少定位时延提高定位精度。
本公开实施例提供的波束测量方法可以应用于进行波束管理并进行参考信号传输交互的设备间。例如，可以是基站等网络设备和终端之间。本公开实施例中为描述方便，将进行参考信号接收与测量并进行测量结果反馈的设备称为第一设备，例如终端，发送参考信号并进行参考信号配置的设备称为第二设备，例如基站等网络设备。
本公开中涉及的第一设备，可以是终端。终端也可以称为终端设备、用户设备(User Equipment，UE)、移动台(Mobile Station，MS)、移动终端(Mobile Terminal，MT)等，是一种向用户提供语音和/或数据连通性的设备，例如，终端可以是具有无线连接功能的手持式设备、车载设备、物联网设备(Internet of Things，IoT)、工业物联网设备(Industry Internet of Things，IIoT)等。目前，一些终端的举例为：智能手机(Mobile Phone)、口袋计算机(Pocket Personal Computer，PPC)、掌上电脑、个人数字助理(Personal Digital Assistant，PDA)、笔记本电脑、平板电脑、可穿戴设备、或者车载设备等。此外，当为车联网(V2X)通信系统时，第一设备还可以是车载设备。应理解，本公开实施例对第一设备所采用的具体技术和具体设备形态不做限定。
本公开实施例中，第二设备包括基于蜂窝网络进行通信的无线网络设备，例如，可以 包括基站等无线接入网设备，也可以包括定位管理功能实体(LMF)等核心网设备。进一步的，本公开中涉及的无线接入网设备可以是：基站、演进型基站(evolved node B，基站)、家庭基站、无线保真(wireless fidelity，WIFI)系统中的接入点(access point，AP)、无线中继节点、无线回传节点、传输点(transmission point，TP)或者发送接收点(transmission and reception point，TRP)等，还可以为NR系统中的gNB，或者，还可以是构成基站的组件或一部分设备等。当为直连通信(D2D)、车联网(V2X)通信系统时，第二设备还可以是终端，例如车载设备。
本公开实施例中，第二设备也可以是基于WLAN进行通信的无线局域网设备、也可以是基于蓝牙(Bluetooth)通信的蓝牙设备，还可以是基于超宽带(Ultra Wide Band，UWB)通信的UWB设备。可以理解的是第二类型定位节点也可以是基于WLAN、Bluetooth以及UWB中的一种或多种无线通信技术进行通信的传感器。应理解，本公开的实施例中，对第二设备所采用的具体技术和具体设备形态不做限定。

图2是根据一示例性实施例示出的一种波束管理方法的流程图，如图2所示，波束管理方法用于第二设备中，包括以下步骤。
在步骤S21中，发送参考信号配置信息。
在步骤S22中，接收第一设备基于参考信号配置信息对参考信号进行测量并反馈的测量结果，测量结果中包括参考信号对应波束的第一到达径信息。
本公开实施例中，第二设备发送参考信号配置信息，第一设备接收参考信号配置信息对参考信号进行测量并反馈测量结果，在测量结果中包括参考信号对应波束的第一到达径信息。第二设备接收第一设备基于参考信号配置信息对参考信号进行测量并反馈的测量结果，测量结果中包括参考信号对应波束的第一到达径信息，可以后续根据第一到达径信息来配置用于定位测量的参考信号，比如尽量配置飞行时间较短的定位参考信号。从而使得第一设备在定位测量过程中能尽快找到first arrival path，减少终端的能耗，同时也能减少定位时延提高定位精度。
本公开实施例以下结合实际应用对本公开实施例中涉及的波束管理方法进行说明。
一种实施方式中，第二设备发送的参考信号配置信息(第一设备接收的参考信号配置信息)可以包括诸如参考信号标识(ID)、时域位置、频域位置等，还可以包括参考信号用途(比如用于波束管理)，以及重复传输是否开启(repetition为on还是off)。其中，repetition为on表示第二设备以同一Tx beam在重复发送多个参考信号，即这多个参考信号的Tx beam一样。这种情况下，第一设备可以使用自己不同的Rx beam来接收这多个参考信号，找出自己最佳的Rx beam。repetition为off表示第二设备以不同Tx beam发送多个参考信号，即这多个参考信号的Tx beam不一样。参考信号配置信息还可以包含参考信号对应的发送接收点(Transmission Reception Point，TRP)ID或小区ID，小区ID可以是第一设备的服务小区ID或邻小区ID。参考信号标识可以是同步信号块(Synchronization Signal Block，SSB)标识、信道状态信息参考信号(Channel-state information RS，CSI-RS)标识，PRS标识或SRS标识。
本公开实施例中第一设备接收参考信号配置信息进行参考信号对应波束的测量。
本公开实施例中第一设备进行参考信号对应波束的测量包括确定波束对应的第一到达径信息。
本公开实施例中第一到达径信息可以表征参考信号对应波束是否为第一到达径。例如，第一到达径信息表征参考信号对应波束为第一到达径，或者第一到达径信息表征参考信号对应波束为非第一到达径。一示例中，第一到达径信息可以体现为是或否，即该参考信号标识对应的波束是否为第一到达径，反馈信息指示为是或否。
本公开实施例中第一到达径信息可以包括参考信号的飞行时间信息。
一种实施方式中，本公开实施例进行参考信号测量可以包括测量每个参考信号的飞行时间。
其中，本公开实施例中飞行时间信息包括多个到达径按照飞行时间长短进行顺序排序的排序信息。一示例中，第一到达径信息体现为飞行时间从小到大的排序。飞行时间最短，则是第一到达径(以2bit为例，比如用00标识)，第二短为第二到达径(比如用01标识)，第三短为第三到达径(比如用11标识)，……依此表示出多个排序的到达径。
其中，本公开实施例中飞行时间信息包括飞行时间值，即第一到达径信息体现为飞行时间值。一种实施方式中，飞行时间值包括飞行时间绝对值，和/或相对所述飞行时间绝对值的飞行时间相对值。一示例中，飞行时间绝对值对应飞行时间最短的参考信号。比如，最短飞行时间值对应的第一到达径信息指示为最短飞行时间的绝对值，其它飞行时间值对应的第一到达径信息指示为相对最短飞行时间绝对值的相对值。另一种实施方式中，飞行时间值包括指定数值，和/或相对指定数值的相对数值。一示例中，指定数值对应飞行时间 最短的参考信号。比如，最短飞行时间值对应的第一到达径信息指示为0，其它飞行时间值对应的第一到达径信息指示为相对0而言的相对值。
一种实施方式中，本公开实施例进行参考信号对应波束的测量包括测量每个参考信号的信号强度。
一种实施方式中，第一设备测量每个参考信号的信号强度和飞行时间，第一设备保存以下参考信号标识、接收波束、信号强度值以及飞行时间等多个元素的一一对应关系。一示例中，参考信号标识、接收波束、信号强度值以及飞行时间之间的对应关系可如下表1所示。
表1
Figure PCTCN2020106070-appb-000001
本公开实施例中，第一设备反馈的测量结果中还可以包括参考信号标识。该参考信号标识可以是同步信号块(Synchronization Signal Block，SSB)标识、信道状态信息参考信号(Channel-state information RS，CSI-RS)标识，也可以是PRS标识或SRS标识。
进一步的，本公开实施例中第一设备反馈的测量结果中还可以包括发送接收点(Transmission Reception Point，TRP)标识和/或小区标识。该小区标识可以是服务小区标识，也可以是邻小区标识。
本公开实施例中，第一设备反馈的参考信号标识与第一到达径信息之间具有对应关系。或者，参考信号标识与参考信号的飞行时间信息之间具有对应关系。
进一步的，参考信号标识也可以与信号强度之间具有对应关系。
本公开实施例中，第一设备可以将信号强度最强的设定数量的参考信号标识进行反馈，和/或将信号飞行时间最短的设定数量的参考信号标识进行反馈。
一示例中，第一设备反馈的是信号强度最强的N(N为自然数，比如N取值为1,2或4)个参考信号标识以及信号强度值。当N为1时，反馈的测量结果中包括信号强度最强的参考信号的标识以及对应的信号强度值，该信号强度值可以是信号强度最强的参考信号对应的信号强度值的绝对值。N大于1时，反馈的测量结果中包括信号强度最强的参考信号的标识以及对应的信号强度值的绝对值，以及其他信号强度值相对信号强度值最强的信 号强度绝对值而言的信号强度相对值。
本公开实施例中，第一设备反馈的测量结果中进一步包括有飞行时间。测量结果中包括的参考信号标识基于信号强度值和/或飞行时间确定。也可以理解为是信号强度值、飞行时间和参考信号标识之间具有对应关系。
一种实施方式中，参考信号标识对应测量得到的信号强度值中信号强度值最强的参考信号，即测量结果中可以包括信号强度最强的N个参考信号的参考信号标识、信号强度值、飞行时间值。另一种实施方式中，参考信号标识对应测量得到的飞行时间中飞行时间最短的一个或多个参考信号，即测量结果中可以包括飞行时间最短的N个参考信号的参考信号标识、信号强度值、飞行时间值。又一种实施方式中，参考信号标识对应测量得到的信号强度值和飞行时间之间的加权和最大的一个或多个参考信号。即，将信号强度和飞行时间分别乘以一个加权值得到加权和，反馈加权和最大的N个参考信号的参考信号标识、信号强度值、飞行时间值。
可以理解的是，本公开实施例中上述涉及的N的取值为大于或等于1的正整数。
本公开实施例中，对于每个参考信号和第一设备的Rx beam，可能测量出一个或多个到达径，如果第一设备能区分出多个径(path)之间的到达时间，那么第一设备可以测量出多个飞行时间值。
本公开实施例一种实施方式中，如果第一到达径信息表针参考信号对应波束为第一到达径或者为非第一到达径，当第一设备测量到多径时，以多径中的第一径为主。另一种实施方式中，如果第一到达径信息表征飞行时间的排序信息，则在测量到多径时，以多径中的第一径为主。又一种实施方式中，如果第一到达径信息表征飞行时间值，则第一设备可以反馈多个径的飞行时间值和信号强度值或者反馈一个径的飞行时间值和信号强度值，或者将多个径的值进行加权平均后再反馈。
进一步的，本公开实施例中第一设备向第二设备反馈的飞行时间可以是单向飞行时间，也可以是双向飞行时间，或者也可以是单向飞行时间和双向飞行时间。
一种实施方式中，飞行时间包括单向飞行时间。假设第二设备发送参考信号的时间为T1，第一设备接收参考信号的时间为T2，那么飞行时间为T2-T1。
本公开实施例中针对T1的定义方式可以有多种方式。一种方式中，基于同步时钟定义。其中，第一设备和第二设备为同步系统，两个设备的同步时钟见图3所示。比如第一设备为终端，第二设备为基站时，下行同步的概念就是基站在slot#0起始位置发送参考信号，终端在slot#0起始位置接收参考信号，那么终端侧的slot#0的起始位置与基站侧的slot#0的起始位置就是相差为参考信号的传输时间。所以，如果第二设备发送参考信号的Tx beam 和第一设备接收参考信号的Rx beam跟当时下行同步时的一样，那么T2-T1就是0，如果不一样，T2-T1可能为正值，也可能为负值。所以这里T1的定义就是第一设备与第二设备同步(主要是下行同步即第一设备根据第二设备发送的参考信号进行同步)后，第一设备端处认为的第二设备发送参考信号的时间，即同步时钟显示的时间。
另一种实施方式中，T1可以基于绝对时钟定义。第二设备T1时刻绝对clock时钟的时间(见图3)，第一设备处绝对clock的时间跟第二设备处绝对clock的时间是完全一样的，所以这里需要第二设备将T1时刻clock时钟的时间通知给第一设备(可以是显示的通知，比如发送时间信息；也可以是隐示的，比如不同参考信号ID/频域/序列等表示不同的时间)。第一设备收到参考信号时clock的时间跟T1时刻clock时钟的时间就是单向飞行时间。
又一种实施方式中，T1可以为一个其它的参考时间，比如T1就是第一设备接收第三设备发送的参考信号的时间，那么第一设备接收第二设备的参考信号的时间为T2，这样出来的T2-T1的意思就是第一设备接收来自第二设备参考信号和第三设备参考信号的时间差值。
可以理解的是，上述示例中以第二设备发送参考信号，第一设备测量时间为例进行说明，但实际执行过程中也可以是第一设备发送参考信号，第二设备测量时间。如果有必要，测量时间的结果还需要发送给对方。
本公开实施例中，T1定义不同，对应的飞行时间值的意义会有不同。故，本公开实施例中涉及的飞行时间值可以是通用时间测量值，有些情况时间测量值为飞行时间，有些情况时间测量值为接收时间差值。
一种实施方式中，飞行时间包括双向飞行时间。例如，第二设备发送第一参考信号的时间为T1，第一设备接收第一参考信号的时间为T2，第一设备发送第二参考信号的时间为T3，第二设备接收第二参考信号的时间为T4，那么双向飞行时间为T4-T1-(T3-T2)。
可以理解的是，本公开实施例中，若飞行时间包括双向飞行时间，则需要第一设备将T3-T2的值发送给第二设备。
进一步可以理解的是，本公开实施例中双向飞行时间可以是第一设备测量，也可以是第二设备测量，还可以是两者都测量。如果有需要，测量时间的结果还需要发送给对方。
本公开实施例提供的波束管理方法，用于定位，主要包括beam测量和反馈中除了反馈参考信号ID和信号强度之外，还要反馈飞行时间测量值，用于第二设备根据时间测量值进行定位用途参考信号的配置，以便第一设备定位测量时，尽快找到first arrival path，从而减少定位时延并提高定位精度。
可以理解的是，本公开实施例提供的波束管理方法，可以应用于第一设备和第二设备进行交互的实施过程中。对于第一设备和第二设备交互实现波束管理方法的实施过程可参阅上述实施例的相关描述，在此不再赘述。
基于相同的构思，本公开实施例还提供一种波束管理装置。
可以理解的是，本公开实施例提供的波束管理装置为了实现上述功能，其包含了执行各个功能相应的硬件结构和/或软件模块。结合本公开实施例中所公开的各示例的单元及算法步骤，本公开实施例能够以硬件或硬件和计算机软件的结合形式来实现。某个功能究竟以硬件还是计算机软件驱动硬件的方式来执行，取决于技术方案的特定应用和设计约束条件。本领域技术人员可以对每个特定的应用来使用不同的方法来实现所描述的功能，但是这种实现不应认为超出本公开实施例的技术方案的范围。
