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所获得的所有其他实施例,都属于本申请保护的范围。

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。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,但是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示意图。无线通信系统包括终端11、无线辅助设备13和网络侧设备12。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 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(Transmitting Receiving Point,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。智能表面设备13可以是大型智能表面设备(Large Intelligent Surfaces,LIS),或者也可以是可重构智能表面(Reconfigurable Intelligent Surfaces,RIS),或者,可以是无源智能表面设备或有源智能表面设备,或者也可以是有源无源结合的智能表面设备,也可以是或者也可以为层一(L1)中继设备,或者也可以是L1的转发器(repeator)、或者反射体(backscatter)。大型智能表面设备也被称为智能反射表面 (IntelligentReflectedSurface)、智能超表面、可编程/重构超表面等。其中,智能表面设备可以具有波束赋形功能,也可以不具备波束赋形功能。
在本申请实施例中,终端11或基站12可以具有通信感知一体化功能。其中,通信感知一体化是指在同一系统中通过频谱共享与硬件共享,实现通信、感知功能一体化设计,系统在进行信息传递的同时,能够感知方位、距离、速度等信息,对目标设备或事件进行检测、跟踪、识别,通信系统与感知系统相辅相成,实现整体性能上的提升并带来更好的服务体验。
通信与雷达的一体化属于典型的通信感知融合应用,在过去,雷达系统与通信系统由于研究对象与关注重点不同而被严格地区分,大部分场景下两系统被分发研究。事实上,雷达与通信系统同样作为信息发送、获取、处理和交换的典型方式,不论工作原理还是系统架构以及频段上存在着不少相似之处。通信与雷达一体化的设计具有较大的可行性,主要体现在以下几个方面:首先,通信系统与感知系统均基于电磁波理论,利用电磁波的发射和接收来完成信息的获取和传递;其次,通信系统与感知系统均具备天线、发送端、接收端、信号处理器等结构,在硬件资源上有很大重叠;随着技术的发展,两者在工作频段上也有越来越多的重合;另外,在信号调制与接收检测、波形设计等关键技术上存在相似性。通信与雷达系统融合能够带来许多优势,例如节约成本、减小尺寸、降低功耗、提升频谱效率、减小互干扰等,从而提升系统整体性能。
由于雷达与通信系统同样作为信息发送、获取、处理和交换的典型方式,不论工作原理还是系统架构以及频段上存在着不少相似之处。因此,可以将通信与雷达一体化的设计。在相关技术中,对于雷达和通信系统的一体化设计包括频谱共存,即两系统独立工作,可以允许信息交换以降低互相之间的干扰;收端共享,此时两系统发端发送各自的信号波形,两系统的波形需要具备正交性,从而不影响各自的接收检测;发端共享,即发送端发射雷达与通信的联合波形;以及收发端共享,即两系统收发两侧进行资源共享,同样 需要使用联合波形或者存在正交关系的波形。
将雷达感知功能引入移动通信系统,在进行感知时,可以是基于单站模式的感知,即收发共址,发送端发射感知信号,然后自己接收回波信号并进行分析,提取感知参数,例如基站作为感知信号的发送端与接收端,终端或其他物体作为感知目标;也可以是基于双站/多站模式的感知,即收发不共址,发送端发射感知信号,其他接收端进行接收并分析,提取感知参数,例如基站A作为感知信号发送端,终端或者基站B作为感知信号接收端。
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。
下面结合附图,通过一些实施例及其应用场景对本申请实施例提供的智能表面设备的识别方案进行详细地说明。
图2示出本申请实施例中的智能表面设备的识别方法的一种流程示意图,该方法200可以由第一通信设备执行。换言之,所述方法可以由安装在第一通信设备上的软件或硬件来执行。如图2所示,该方法可以包括以下步骤。
S210,第一通信设备发送第一信号。
在本申请实施例中,第一通信设备可以为基站,也可以为终端。第一通信设备可以具备雷达感知功能。
在本申请实施例中,第一信号可以为探测信号。例如,第一通信设备需要获知周围环境中是否有智能表面设备时,可以向周围环境发送探测信号。
在本申请实施例中,第一信号可以包括以下(1)至(3)之一。
(1)用于实现感知功能的感知信号。例如,第一信号为用于感知目标物体、事件或环境的信号,例如雷达信号,如脉冲信号或调频连续波信号。
(2)用于传输信息的通信信号。即所述第一信号是仅用于收发之间信息传递的信号。例如,同步信号/物理广播信道信号块(或同步信号块)(Synchronization Signal and PBCH block,SSB)等。
(3)用于实现感知功能以及传输信息的通信感知一体化信号。也就是说, 所述第一信号是可以用于通信也可以用于实现感知功能的信号。
在本申请实施例中,第一通信设备发送第一信号可以通过波束扫描的方式发送,或也同时发送多个波束的方式发送,或者全向发送的方式发送。例如,第一通信设备可以根据波束角度集合{α1,α2,α3,…,αn}通过波束扫描的方式发送第一信号,即不同时刻向不同方向发送波束。
S212,所述第一通信设备获取智能表面设备相关的识别信息,其中,所述识别信息为所述第一通信设备对所述第一信号的回波信号进行检测得到的信息,或第二通信设备对所述第一信号的回波信号进行检测得到并转发给所述第一通信设备的信息。
在本申请实施例中,智能表面设备在接收第一信号后,将对第一信号进行反射,即发送第一信号的回波信号,利用智能表面设备能够对回波进行增加或控制的特点,通过监听智能表面设备发送的回波信号,可以识别第一通信设备当前通信环境中的智能表面设备。
在本申请实施例的一个可能的实现方式中,为了使智能表面设备能够对第一信号进行回波,可以在第一信号中包括控制命令,其中,所述控制命令用于控制所述智能表面设备反射所述第一信号的反射模式。即通过控制命令控制智能表面设备反射第一信号的反射模式。例如,可以控制智能表面设备反射第一信号的角度。可选地,所述控制命令可以与所述智能表面设备预先设置的波束转发角度集合中的至少一个角度相关联。在该可能的实现方式中,第一通信设备每次发送第一信号中对智能表面设备的信号反射模式(也可以称为转发模式)的控制命令与智能表面设备预先设置的波束转发角度集合中至少一个角度相关联。
例如,当第一信号为用于传输信息的通信信号或用于实现感知功能以及传输信息的通信感知一体化信号时,第一信号中可以包含所述控制命令。
在另一个可能的实现方式中,第一通信设备可以发送第一触发信号,其中,所述第一触发信号用于触发所述智能表面设备采用特定的反射模式。通 过该可能的实现方式,可以通过第一触发信号,触发所述智能表面设备采用特定的反射模式,从而使得智能表面设备可以按照约定的方式对第一信号进行反射。
在具体应用中,第一通信设备在发射第一触发信号时,可以通过全向发送的方式,或根据波束角度集合{α1,α2,α3,…,αn}通过波束扫描的方式,即不同时刻向不同方向发送波束,或多波束发送的方式等方式发送。
可选地,所述第一触发信号包含在所述第一信号中。例如,当第一信号为用于传输信息的通信信号或用于实现感知功能以及传输信息的通信感知一体化信号时,第一信号中可以包含所述第一触发信号。例如,第一通信设备可以在在第一次的第一信号或前几次的第一信号发射时,在第一信号中携带所述第一触发信号。
可选地,第一通信设备可以以广播的方式发送所述第一触发信号,以触发智能表面设备的所述特定的反射模式。
在一个可能的实现方式中,为了保证安全,第一通信设备还可以在第一信号中包括身份指示信息,其中,所述身份指示信息用于指示所述第一通信设备的身份。智能表面设备可以根据身份指示信息确定第一通信设备是否为合法设备,即第一信号是否为合法的探测信号。例如,在用于传输信息的通信信号或用于实现感知功能以及传输信息的通信感知一体化信号中包括基站或终端的特定身份信息等有效性指示信息,当智能表面设备识别不出有效的指示信息时,不进行信号的有效反射。例如,基站或终端发射的探测信号中包含事先约定的信号格式,智能表面设备通过对接收信号的监听与检测确定是否为包含基站或终端身份有效性指示信息的合法探测信号。又例如,基站或终端发射的通信信号或通信感知一体化信号中包含与自身身份信息相关联的训练序列,智能表面设备通过匹配滤波检测峰值是否超过门限的方式确定是否为合法探测信号。
在又一个可能的实现方式中,智能表面设备的默认反射模式可以为所述 特定的反射模式。在该可能的实现方式中,为了使智能表面设备能够在识别后正常的执行转发工作,在S212之后,该方法还可以包括:所述第一通信设备向所述智能表面设备发送第一指示信息,其中,所述第一指示信息指示所述智能表面设备退出特定的反射模式,所述特定的反射模式为所述智能表面设备的默认反射模式。也就是说,在该可能的实现方式中,智能表面设备的默认配置和/或预配置为所述特定的反射模式,即在无信号转发行为时(即无相关联的服务基站或终端时),智能表面设备按默认配置转发信号、在当基站或终端完成识别后指示其停止使用默认转发模式的设置。
在一个可能的实现方式中,所述特定的反射模式可以包括以下(1)和(2)之一。
(1)第一反射模式。其中,在所述第一反射模式下,所述智能表面设备采用预先设置的波束转发角度集合中的角度反射接收到的信号。在该可能的实现方式中,波束转发角度集合中从最小角度到最大角度变化范围包含与入射角度相对应的反射角度,即发射机所在的方位角度,或潜在的接收机所在方位角度。即智能表面设备根据预先设置的转发波束角度集合{θ1,θ2,θ3,…,θn}进行反射,假设θ1<θ2<θ3<…<θn,与入射角度对应的反射角度α与集合中的角度满足关系θ1≤α≤θn。
其中,在第一反射模式下,一个第一信号可以对应所述波束转发角度集合的各个角度,即针对一个第一信号,智能表面设备对所述波束转发角度集合中的角度进行遍历反射。在这种情况下,所述第一通信设备发送单个所述第一信号的第一持续时间至少大于所述智能表面设备遍历所述波束转发角度集合中各个角度时所需的模式切换总时间。在该可能的实现方式中,智能表面设备在接收到第一信号(例如,探测脉冲信号)后,在单个第一信号的持续时间根据角度集合中的角度进行遍历反射,如图3所示。
或者,在第一反射模式下,一个所述第一信号对应所述波束转发角度集合的一个角度,即针对一个第一信号,智能表面设备以所述波束转发角度集 合中的一个角度进行反射。在这种情况下,所述第一通信设备采用同一个角度和/或同一个波束方向发送的所述第一信号的数量至少大于所述波束转发角度集合中的角度的数量。在该可能的实现方式中,如图4所示,智能表面设备在单个脉冲信号(即第一信号)持续时间根据角度集合中的一个角度进行反射,在该可能的实现方式中,第一通信设备对每个方向的发射脉冲个数至少要大于等于智能表面预设角度集合中的元素个数。可选地,也可以在多个脉冲信号(即第一信号)的持续时间根据角度集合中的一个角度进行反射,即一个反射角度对应多个脉冲信号,便于第一通信设备进行回波脉冲累积检测,提高检测性能。在这种情况下,第一通信设备对每个方向的发射脉冲个数至少大于或等于智能表面预设角度集合中的元素个数与每个角度对应的脉冲信号个数的乘积。
在上述情况下,为了保证第一通信设备能够监听到各个第一信号对应的回波信号,所述第一通信设备采用同一个角度和/或同一个波束方向发送的下一个所述第一信号的起始时刻晚于上一个所述第一信号的回波监听的终止时刻。
(2)第二反射模式。其中,在所述第二反射模式下,所述智能表面设备采用与来波方向对应的角度反射接收到的信号。也就是说,在该可能的实现方式中,智能表面设备可以按照来波方向形成转发波束将信号全部反射,在该可能的实现方式中,智能表面设备中可以含有有源单元,通过该有源单元,可以进行AoA估计,以得到第一信号的来波方向。
在一个可能的实现方式中,第一通信设备在发送第一信号后,可以对第一信号的回波信号进行监听,其中,监听的第二持续时间可以根据第一通信设备的最大探测距离和/或发送单个所述第一信号的第一持续时间的。例如,对于图4所示的反射模式,第一通信设备可以根据最大探测距离Dmax来确定监听的第二持续时间,对于图3所示的反射模式,第一通信设备可以根据第一信号的第一持续时间来确定监听的第二持续时间。或者,第一通信设备 也可以根据最大探测距离和第一持续时间来确定第二持续时间,例如,第二持续时间T1与最大探测距离Dmax以与第一信号持续时间T满足以下关系:
Tl≥2Dmax/c+T,其中c为光速。
在一个可能的实现方式中,第一通信设备在监听到第一信号的回波信号之后,可以根据监听到的回波信号的强度,确定在所述第一信号的发射角度和/或波束方向是否存在智能表面设备。例如,通过接收信号强度指示(Received Signal Strength Indication,RSSI)或者对回波进行相关后的相关峰值与门限的关系判断在当前波束方向是否存在智能表面,若RSSI或者相关峰值超过门限则认为第一信号的发射方向和/或波束方向存在智能表面设备,否则认为第一信号的发射方向和/或波束方向不存在智能表面设备。
例如,如果第一通信设备在全双工模式,监听起始时刻可以至少从发送探测信号开始,如图5所示,第一通信设备在特定方向α1发射的脉冲探测信号的起始时刻开始监听回波信号。当然,并不限于此,第一通信设备可以根据其最大探测距离Dmax确定其开始接收到回波信号的最晚时刻,则只要在该时刻之前,开始进行监听也是可行的,具体本申请实施例中不作限定。
如果第一通信设备在半双工模式,则如图6所示,监听起始时刻可以至少从探测信号发送完毕开始。当然,也并不限于此,第一通信设备可以根据其最大探测距离Dmax确定其开始接收到回波信号的最晚时刻,则只要在该时刻之前,开始进行监听也是可行的,具体本申请实施例中不作限定。
在本申请实施例的一个可能的实现方式中,智能表面设备在对第一信号进行反射时,还可以按照第一规则,改变第一信号的特性信息,以在回波信号中指示其身份信息。因此,在该可能的实现方式中,第一通信设备获取所述识别信息还可以包括:所述第一通信设备检测所述回波信号的特性信息,根据检测结果识别所述智能表面设备的身份信息,其中,所述特性信息包括以下至少之一:幅度、相位、极化、以及轨道角动量信息。进一步地,第一通信设备还可以通过回波信号进行分析得到对应智能表面设备的距离、移动 速度、角度等信息。
在一个可能的实现方式中,第一通信设备还可以与第二通信设备协作,实现对智能表面设备的识别。在该可能的实现方式中,所述第一通信设备获取识别信息,包括:所述第一通信设备向所述第二通信设备发送第二指示信息,其中,所述第二指示信息至少包括以下之一:启动回波监听的指示、以及所述第一信号的格式;所述第一通信设备接收所述第二通信设备发送的所述识别信息,其中,所述识别信息为所述第二通信设备对所述第一信号的回波信号进行监测并分析得到的,所述识别信息包括:第三指示信息,所述第三指示信息用于指示在所述第一信号的发射角度和/或波束方向是否存在智能表面设备。
在具体应用中,第二通信设备在接收到第一通信设备发送的所述第二指示信息后,可以采用与第一通信设备相同的方式对第一信号的回波信号进行监测并分析得到所述识别信息,具体本申请实施例中不再赘述。
可选地,第二通信设备返回的识别信息也可以包括智能表面设备的身份信息。
在一个可能的实现方式中,第二通信设备也可以只将监听到的第一信号的回波信号的相关信息返回给第一通信设备,由第一通信设备根据回波信号的相关信息进行分析得到所述识别信息。
在上述可能的实现方式中,第二通信设备可以在监听到一个第一信号的回波信号后,向第一通信设备返回一次该回波信号对应的识别信息。或者,第一通信设备可以在第二指示信息中指示第一信号的格式,其中,第一信号的格式包括以下至少之一:所述第一信号的波形、序列信息、发送角度、和波束方向。则可选地,第二通信设备返回的识别信息中还可以包括目标发送角度和/或目标波束方向,其中,所述目标发送角度和/或目标波束方向为所述回波信号对应的第一信号的发送角度和/或波束方向。在这种情况下,第二通信设备可以在监听并分析到多个第一信号的回波信号后,再统一向第一通信 设备返回对应多个第一信号的识别信息。
在本申请实施例中,第二通信设备可以是基站,也可以是终端,具体本申请实施例中不作限定。
例如,基站A向基站B发送指示信息,该指示信息可以包括启动回波监听指示、所发送探测信号格式等。基站B接收基站A的指示信息并启动侦听。基站A向周围环境发射第一触发信号(可选地)。基站A向周围环境发射探测信号。智能表面设备工作在特定的反射模式反射探测信号。基站B接收并分析回波特征,确定基站A发送所述探测信号的发射方向和/或发送波束方向是否存在智能表面设备,进一步地,还可以获取智能表面身份信息。基站B向基站A反馈信息,至少包含基站A发送所述探测信号的发射方向和/或发送波束方向是否存在智能表面设备指示信息,还可以包括智能表面设备的身份指示信息等。
又例如,基站向终端发送指示信息,该指示信息可以包括启动回波监听指示、所发送探测信号格式等。终端接收基站的指示信息并启动侦听。基站向周围环境发射第一触发信号(可选步骤)。基站向周围环境发射探测信号。智能表面设备工作在特定的反射模式反射探测信号。终端接收并分析回波特征,确定基站发送所述探测信号的发射方向和/或发送波束方向是否存在智能表面设备,进一步地,还可以获取智能表面身份信息。终端向基站反馈信息,至少包含基站发送所述探测信号的发射方向和/或发送波束方向是否存在智能表面设备指示信息,还可以包括智能表面设备的身份指示信息等。
通过本申请实施例提供的技术方案,在基站或终端具备雷达感知功能时,可以利用回波信号对周围环境中的智能表面设备进行探测和识别。
