终端信息获取方法、终端及网络侧设备
交叉引用
本发明要求在2020年07月17日提交中国专利局、申请号为202010693760.0、发明名称为“终端信息获取方法、终端及网络侧设备”的中国专利申请的优先权，该申请的全部内容通过引用结合在本发明中。
技术领域
本申请属于无线通信技术领域，具体涉及一种终端信息获取方法、终端及网络侧设备。
背景技术
智能表面是一种新兴的技术，智能表面设备也可以称之为大型智能表面(Large Intelligent Surface，LIS)、智能反射阵列(Smart Reflect Array，SRA)、可配置反射阵列(Reconfigurable Reflect Array，RRA)或智能反射表面(Intelligent Reflecting Surface，IRS)。
智能反射表面IRS由大量低成本无源反射元件组成，IRS是一种电磁超材料(Electromagnetic Metamaterial)或者超表面(Metasurface)。每个反射元件能够独立地诱导入射信号的振幅和/或相位和/或极化方式的变化，即通过控制反射来重新配置无线传播环境。
与现有的有源中继通信相比，IRS不使用有源发射模块，而仅将接收到的信号反射。有源中继通信通常以半双工模式运行，其频谱效率低于以全双工模式运行的IRS。与现有的反向散射通信(例如射频识别(Radio Frequency Identification，RFID)相比，IRS作为无源反射器件，不发送其自身的信息， 仅仅用于促进现有的通信链接。IRS为无源阵列，一般用作反射阵列，相比于大规模多输入多输出(Multi Input Multi Output，MIMO)技术，IRS具有低硬件成本、低传输损耗、更适用于毫米级频段(mmWave)等优点。
在某些情况下，终端(UE)位于智能表面设备或者中继类设备(repeater)的覆盖范围，但是超出了与智能表面或者repeater关联的基站的覆盖范围，但由于智能表面设备或中继类设备一般只进行转发，而不进行信息获取，因此，不能获知终端的相关信息。

具体实施方式
下面将结合本申请实施例中的附图，对本申请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申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，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，都属于本申请保护的范围。
本申请的说明书和权利要求书中的术语“第一”、“第二”等是用于区别类似的对象，而不用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便本申请的实施例能够以除了在这里图示或描述的那些以外的顺序实施，且“第一”、“第二”所区别的对象通常为一类，并不限定对象的个数，例如第一对象可以是一个，也可以是多个。此外，说明书以及权利要求中“和/或”表示所连接对象的至少其中之一，字符“/”一般表示前后关联对象是一种“或”的关系。
值得指出的是，本申请实施例所描述的技术不限于长期演进型(Long Term Evolution，LTE)/LTE的演进(LTE-Advanced，LTE-A)系统，还可用于其他无线通信系统，诸如码分多址(Code Division Multiple Access，CDMA)、时分多址(Time Division Multiple Access，TDMA)、频分多址(Frequency Division Multiple Access，FDMA)、正交频分多址(Orthogonal Frequency Division Multiple Access，OFDMA)、单载波频分多址(Single-carrier Frequency-Division Multiple Access，SC-FDMA)和其他系统。本申请实施例中的术语“系统”和“网络”常被可互换地使用，所描述的技术既可用于以上提及的系统和无线电技术，也可用于其他系统和无线电技术。然而，以下描述出于示例目的描述了新空口(NewRadio，NR)系统，并且在以下大部分描述中使用NR术语，尽管这些技术也可应用于NR系统应用以外的应用，如第6代(6 thGeneration，6G)通信系统。
图1示出本申请实施例可应用的一种无线通信系统的框图。无线通信系统包括终端11、网络侧设备12和第一网络节点13。其中，终端11也可以称作终端设备或者用户终端(User Equipment，UE)，终端11可以是手机、平 板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)或称为笔记本电脑、个人数字助理(Personal Digital Assistant，PDA)、掌上电脑、上网本、超级移动个人计算机(ultra-mobile personal computer，UMPC)、移动上网装置(Mobile Internet Device，MID)、可穿戴式设备(Wearable Device)或车载设备(VUE)、行人终端(PUE)等终端侧设备，可穿戴式设备包括：手环、耳机、眼镜等。需要说明的是，在本申请实施例并不限定终端11的具体类型。网络侧设备12可以是基站或核心网，其中，基站可被称为节点B、演进节点B、接入点、基收发机站(Base Transceiver Station，BTS)、无线电基站、无线电收发机、基本服务集(Basic Service Set，BSS)、扩展服务集(Extended Service Set，ESS)、B节点、演进型B节点(eNB)、家用B节点、家用演进型B节点、WLAN接入点、WiFi节点、发送接收点(TransmittingReceivingPoint，TRP)或所述领域中其他某个合适的术语，只要达到相同的技术效果，所述基站不限于特定技术词汇，需要说明的是，在本申请实施例中仅以NR系统中的基站为例，但是并不限定基站的具体类型。
第一网络节点13可以为智能表面类设备或中继类设备(repeater)。其中，智能表面类设备包括但不限于：智能反射表面(IRS)设备、大型智能表面(LIS)、智能反射阵列(SRA)以及可配置反射阵列(RRA)，智能表面类设备的每个反射元件能够独立地诱导入射信号的振幅和/或相位和/或极化方式的变化，即通过控制反射来重新配置无线传播环境。并且，智能表面类设备不使用发射RF链，且只在短距离内工作，因此可以密集部署。与现有的反向散射通信(例如RFID)相比，IRS作为无源反射器件，不发送其自身的信息，仅仅用于促进现有的通信链接；与现有的大规模MIMO技术相比，IRS为无源阵列，而大规模MIMO为有源阵列；IRS一般用作反射阵列，而大规模MIMO一般用作传输阵。
IRS反射单元种类主要有以下几种：A.可调谐谐振器：一个可变电容器被整合到谐振器中，通过改变频率捷变(frequency-agile)贴片谐振器频率， 产生相移。B.导波控制法：在这种情况下，到达的空间波被天线耦合到导波上，随后导波相移，再重新发射，形成了一个天线移相器。C.圆极化波的旋转技术：利用电磁波的反射规律进行设计。
从是否可动态控制的角度划分，反射阵列/智能表面分为两大类：
1)静态的反射阵列/智能表面：反射阵列的结构和功能可以是固定的，对于一个角度的入射波，超表面单元导致入射波的幅度、相位、极化方式等特性发生固定的改变，得到相应的反射波。
2)动态的反射阵列/智能表面：反射阵列的结构和功能是可以控制的，对于一个角度的入射波，可以通过可编程控制使得入射波的幅度、相位、极化方式等特性发生不同的改变，得到相应的反射波。对反射超表面实现可编程控制，须在反射单元中引入开关元件(如二极管、RF-MEMS开关等)。
其中，PIN二极管是目前控制可重构超表面的常见选择，PIN二极管具备较宽范围的射频阻抗，并且失真低，在微波射频领域具有广泛应用。反射单元中的开关元件使其具有多个不同的状态，并且通过控制开关元件的通断可实现不同状态的切换。开关元件在通、断两种情况下，对应反射单元的结构和性能均有较大变化。即，不同状态的反射单元对入射波的幅度、相位、极化等特性有不同的调控模式。
下面结合附图，通过具体的实施例及其应用场景对本申请实施例提供的技术方案进行详细地说明。
图2示出本申请实施例中的终端信息获取方法的一种流程示意图，该方法200可以由第一网络节点执行。换言之，所述方法可以由安装在第一网络节点上的软件或硬件来执行，其中，第一网络节点可以为智能表面类设备或中继类设备。如图2所示，该方法可以包括以下步骤。
S210，接收终端发送的第一信号。
在本申请实施例中，终端可以使用某一波束发送第一信号。在一个可能的实现方式中，终端可以通过时域重复方式发送第一信号，即在时域上重复 的发送第一信号。因此，该可能的实现方式中，S210可以包括：接收终端通过时域重复方式发送的第一信号。通过该可能的实现方式中，终端通过在时域上重复发送第一信号，可以增加第一网络节点接收该第一信号的成功率。
在上述可能的实现方式中，为了进一步保证第一网络节点接收第一信号的成功率，在一个可能的实现方式中，通过时域重复方式发送的所述第一信号所使用的波束不同，即终端在不同时刻发送所述第一信号所使用的波束不同，从而可以避免由于某个波束的被遮挡等原因而导致第一网络节点接收第一信号不成功的问题。并且，终端在不同时刻使用不同波束发送第一信号，还可以增加第一网络节点获取到终端更多的波束信息。当然，并不限于此，通过时域重复方式发送的所述第一信号所使用的波束相同，即终端在不同时刻发送第一信号所使用的波束也可以相同。
在一个可能的实现方式中，由于第一网络节点并不知晓终端发送第一信号所使用的波束，因此，在S210中，第一网络节点可以以接收波束轮询的方式，接收终端发送的第一信号。比如，假设第一网络节点有4个接收波束，则第一网络节点可以先以第1个接收波束进行接收，然后以第2个接收波束进行接收，再以第3个接收波束进行接收，然后以第4个接收波束进行接收，接下来再以第1个接收波束进行接收，如此轮询的方式进行接收。
在一个可能的实现方式中，第一信号可以通过预定信号承载。例如，第一信号通过以下信号之一承载：探测参考信号(Sounding Reference Signal，SRS)；解调参考信号(Demodulation Reference Signal，DMRS)；随机接入信道(RACH)序列，例如，随机接入前导(preamble)；第一信号的专用序列。在该可能的实现方式中，第一网络节点可以根据时间轮询接收波束的方式来接收第一信号。
在一个可能的实现方式中，第一信号的格式可以由网络侧配置，或者，预先设置的，例如，协议约定。例如，网络侧可以预先配置第一信号采用上述的某一种信号承载，即第一信号的序列相关信息。例如，网络侧可以预先 配置或协议可以预先约定第一信号的序列格式与终端标识的关联方式等。当然，并不限于此，例如，网络侧可以配置或协议可以约定第一信号发送的时频资源，而不对第一信号的具体格式进行限定。
在一个可能的实现方式中，在S210中，在接收第一信号时，第一网络节点可以通过序列检测的方式，获得第一信号。例如，如果网络侧配置了第一信号的序列格式与终端标识的关联方式，则第一网络节点可以通过序列检测的方式，确定发送第一信号的终端。和/或，第一网络节点还可以通过能量检测的方式，获知所述第一信号。例如，终端可以检测在某个接收波束上的能量是否达到或者超过预设门限，从而获知第四信号。
在一个可能的实现方式中，第一网络节点可以通过其第一模块(即具有接收功能的模块)完成上述第一信号的接收。
S212，根据所述第一信号，估计所述终端的第一信息，其中，所述第一信息包括以下至少一项：所述终端的位置信息、所述终端的方向信息、与所述终端对应的接收波束信息、与所述终端对应的发送波束信息。
例如，如果网络侧配置了第一信号的序列格式与终端标识的关联方式，则第一网络节点可以通过序列检测的方式，确定发送第一信号的终端。根据接收第一信号使用的接收波束，确定与终端对应的接收波束信号和与终端对应的发送波束信号。通过接收到第一信号的强度等信息，估计终端相对于网络侧设备的方向信息等。
在终端位于智能表面类设备或者repeater的覆盖范围，但是超出了与智能表面类设备或者repeater关联的基站的覆盖范围，为了使基站发现并服务这些终端，在一个可能的实现方式中，在S212之后，该方法还可以包括：向第二网络节点发送第二信号，其中，所述第二信号携带有所述第一信息的全部或者部分内容，第二网络节点为与所述第一网络节点关联的基站类节点。例如，第二网络节点可以为图1中的网络侧设备12。
在一个可能的实现方式，所述第二信号还包括以下(1)至(3)中的至 少一项。
(1)与所述终端的标识相关的信息。例如SRS、DMRS、RACH或者其他信号的序列相关信息等例如扰码序列索引(index)，以帮助基站识别该终端；例如，还可以为在不同接收波束上收到的序列信息；
(2)接收到的所述第一信号的索引。
(3)各个所述索引对应的第一信号的强度相关信息。
其中，索引是用于标识接收到的第一信号，而强度相关信息则指示该索引对应的第一信号的强度信息，例如，在不同接收波束(对应不同索引)上收到的能量和/或功率信息。
在一个可能的实现方式中，第一网络节点可以通过其第三模块(即具有发送功能的模块)上报所述第二信号。
在一个可能的实现方式，所述第一网络节点上报所述第二信号，还可以包括：第一网络节点将第三信息通过控制信息传递给第二网络节点(如gNB)。第三信息可以指示该UE所需的用于波束管理的资源信息，用于波束管理的资源至少可以包括CSI-RS资源和/或SRS资源。所述资源信息至少包括单端口CSI-RS/SRS资源数目或所需的总端口数目。
其中，所述第三信息可以基于第一网络节点接收到的UE第一信号质量确定。
在一个可能的实现方式中，在向第二网络节点发送第二信号之后，该方法还可以包括：接收所述第二网络节点发送的第三信号；按照所述第三信号，调整所述第一网络节点的传输模式。通过该可能的实现方式中，第二网络节点可以根据接收到第二信号，判断是否需要调整第一网络节点的传输模式以及如何调整第一网络节点的传输模式，并向第一网络节点发送相应的第三信号，以调整第一网络节点的传输模式，从而提高第一网络节点发送信号或接收信号的质量。
在一个可能的实现方式中，调整传输模式可以包括：调整以下至少一项： 波束；传输配置索引(Transmission Configuration Index，TCI)信息；准共址(Quasi-Colocation，QCL)信息。通过该可能的实现方式，可以提高第一网络节点发送信息和/或接收信号的质量。
其中，第一网络节点可以是智能表面类设备或者repeater等非基站的设备。如果第一网络节点是智能表面类设备，该智能表面类设备可选的具有接收信号功能的第一模块以及具有调整外来信号相位、幅度或极化方式功能的第二模块。例如，第一模块可以仅支持能量检测或者序列接收功能而不支持信道译码等复杂功能。可选的，该智能表面类设备还可以具有第三模块，支持向终端或基站发送自己的信息。
因此，在上述可能的实现方式中，按照所述第三信号，调整所述第一网络节点的传输模式可以包括：根据所述第三信号，调整所述第一网络节点中的反射单元和/或折射单元的状态。
也就是说，第一网络节点的传输模式可以通过调整第一网络节点设备中反射或折射单元的开关元件的开关图案来实现。传输模式与波束方向有关，上述开关元件使反射单元或折射单元具有多个不同的状态，通过控制开关元件的通和断开实现不同状态的切换，其中，不同状态对应的反射波或折射波的方向、相位、幅度和/或极化方式不同。例如，用1代表开关元件通，用0代表开关元件断。则一个100乘100的发射单元的开关元件的图案就是100乘100维度的01比特矩阵。
如果第一网络节点是repeater，该repeater可以是直接转发、透明转发、放大转发或者对信号进行解调再发送等多种repeater中的任意一种，对此本申请实施例不作限定。
可选的，该repeater具有接收信号的第一模块和转发信号的第二模块；可选的，该repeater还具有第三模块，支持向终端或基站发送自己的信息。
其中，与第一网络节点关联的基站可以具有以下特征：该基站通过向第一网络节点发送信令来控制第一网络节点的传输模式(例如波束/TCI/QCL)， 或，该基站的发送信号和接收信号通过第一网络节点来转发。
在一个可能的实现方式中，第一网络节点也可以直接根据估计的所述终端的第一信息，调整与终端关联的发送波束和/或接收波束。因此，在该可能的实现方式中，在S212之后，该方法还可以包括：根据所述第一信息，调整与所述终端关联的发送波束和/或接收波束。例如，第一网络节点可以根据估计出的终端的方向信息，调整其发送波束和/或接收波束，以提高第一网络节点与终端之间传输的信号质量。例如，第一网络节点可以通过调整其第二模块来实现。
通过本申请实施例提供的上述技术方案，第一网络节点(包括智能表面类设备或中继类设备)在接收到终端发送的第一信号后，根据第一信号，对终端的第一信息进行估计，从而可以获取终端的位置信息、方向信息、接收波束信息或发送波束信息，进而可以根据第一信息获取终端的相关信息，解决了智能表面设备或中继类设备无法获知终端的相关信息的问题。
并且，在本申请实施例中，第一网络节点还可以将获取的第一信息转发给其关联的基站，基站基于第一网络节点的上报，可以获知终端并与终端进行通讯。另外，基站还可以基于获取的信息向第一网络节点发送第三信号，以调整第一网络节点的传输模式，提高通信质量。或者，第一网络节点也可以根据估计得到的第一信息，调整与终端关联的发送波束和/或接收波束，以提高与终端之间的信号传输质量。
图3示出了本申请实施例的终端信息获取方法的另一种流程示意图，该方法300可以由终端、第一网络节点和基站执行，其中，基站即为上述方法200中的第二网络节点。换言之，所述方法可以由安装在终端、第一网络节点和基站上的软件或硬件来执行。如图3所示，该方法可以包括以下步骤。
S310，终端(UE)向第一网络节点发送第一信号。
可选地，UE可以通过时域重复方式发送第一信号，例如，通过在不同时刻以不同的或相同的波束来发第一信号。
S312，第一网络节点接收UE发送的第一信号。
其中，第一信号可以通过SRS、DMRS、RACH序列或者其他序列(例如专用序列等)承载。
第一网络节点可以根据时间轮询接收波束的方式来接收第一信号，其中，第一信号的格式例如序列相关信息可以通过网络侧配置或者由协议约定。例如协议约定了序列格式与UE ID的关联方式等；或者，也可以只约定第一信号发送的时频资源，信号具体格式不做限定。
可选地，第一网络节点可以通过第一模块(具有信号接收功能的模块)完成上述接收。
可选地，第一网络节点以接收波束轮询方式接收第一信号。
其中，S312与方法200中的S210相似，具体可以参见上述方法200中关于S210的描述。
S314，第一网络节点根据接收到的UE的第一信号，估计UE的第一信息，第一信息包括但不限于UE的位置信息、方向信息、对应的第一网络节点的接收波束和/或发送波束中的一项或多项。
可选地，第一网络节点可以通过序列检测，获得UE发送的第一信号。
可选地，第一网络节点也可以通过能量检测，获知UE发送的第一信号。
S314与上述方法200中的S212相似，其它未描述细节可以参见上述方法200中关于S212的描述。
第一网络节点在确定UE的第一信号后，可以调整自己与该UE关联的发送波束和/或接收波束，以提高第一网络节点与UE之间的信号传输质量。
可选地，第一网络节点也可以向基站上报第二信号，协助终端完成面向与第一网络节点关联的基站的收发。因此，在S314之后，还可以包括S316和S318。
S316，第一网络节点通过第三模块(具有信号发送功能的模块)将第二信号上报给与第一网络节点关联的基站。
其中，第二信号可以包括第一网络节点估计到的UE对应的第一网络节点的接收/发送波束信息或者位置信息或者方向信息。
可选地，第二信号还可以包括UE ID相关信息，例如SRS，DMRS，RACH或者其他信号的序列相关信息等例如扰码序列index，以帮助基站识别该UE；例如还可以包括在不同接收波束上收到的序列信息
可选地，第二信号还可以包括第一网络节点接收到的第一信号的能量信息/功率信息，例如在不同接收波束上收到的能量信息/功率信息。
S318，基站向第一网络节点发送信令(即第三信号)调整第一网络节点的传输模式，以调整第一网络节点的发送行为和/或接收行为。
具体调整方式可以参见上述方法200中的相关描述，在此不再赘述。
通过本申请实施例提供的上述方法，第一网络节点接收UE发送的信号，并确定UE的位置信息、方向信息、接收波束信息或发送波束信息等，并将信息上报给基站，从而使得基站能够据此确定第一网络节点和UE之间的波束方向，便于基站发送该UE，并为该UE提供服务，解决UE和第一网络节点对应的基站间的通信问题。
图4示出本申请实施例提供的信号接收方法的一种流程示意图，该方法400可以由终端执行。换言之，所述方法可以由安装在终端上的软件或硬件来执行。如图4所示，该方法可以包括以下步骤。
S410，接收第一网络节点发送的第四信号，其中，所述第一网络节点为智能表面类设备或中继类设备。
在一个可能的实现方式中，第四信号中承载有第二信息，所述第二信息可以包括以下(1)至(5)中的至少一项。
(1)同步信息。
通过该信息可以实现终端与第一网络节点之间的同步。
(2)所述第一网络节点的标识信息。
通过该信息，终端可以获知发送第四信号的第一网络节点。
(3)所述第一网络节点的波束信息。
通过该信息，终端可以获知第一网络节点可以使用的波束信息，从而确定向第一网络节点发送信号时可以使用的波束信息。
(4)所述第一网络节点转发的时间窗。
通过该信息，终端可以获知第一网络节点执行转发的时间窗，即第一网络节点在该时间窗内转发信号，终端可以在这个时间窗内发送传输给基站的、而无需第一网络节点处理的信号，第一网络节点将该时间窗接收到的信号透传给基站。
(5)与所述第一网络节点的波束信息关联的时间信息。
通过该信息，终端可以获知第一网络节点可以使用的波束信息，以及不同波束对应的时间信息，例如波束1对应的时间是一个TDD周期(假设由2个下行时隙和两个上行时隙组成)内的第1个下行时隙和第2个上行时隙，波束2对应的时间是一个TDD周期内的第2个下行时隙和第1个上行时隙。终端因而确定向第一网络节点发送信号时可以使用的波束信息和时隙，以及确定从第一网络节点接收信号时可以使用的波束信息和时隙。
例如，第一网络节点可以以波束扫描的形式或者广播的形式向UE发送第四信号。
可选地，第一网络节点通过第三模块(具有信号发射功能的模块)来发送第四信号。
在一个可能的实现方式中，S410可以包括以下(1)至(3)中的至少一项。
(1)以接收波束轮询方式接收第四信号。
即终端在时间上以其接收波束轮询的方式，检测是否有第四信号传输，并接收传输的第四信号。
(2)通过序列检测，获得所述第四信号。
