图1a是根据本公开实施例示出的通信系统的架构示意图。
如图1a所示,通信系统100包括终端101和网络设备102。
在一些实施例中,终端101可以是Ambient-IoT终端或称为设备(device)。终端101可以不配置电池,通过接收的电磁信号激发和供电;或者配置具有少量电存储功能的电池,并通过获取外界的电磁波、热能、动能等等方式来获得该电池的能量。
可选地,根据终端101的类型和工作方式不同,其电量获取和存储能力不同。例如,终端101的类型可以包括以下几种:
设备(Device)1:不能进行独立的信号产生或放大。例如,设备1使用反向散射的工作方式或反向散射通信,不具备下行(Downlink,DL)信号和/或上行(Uplink,UL)信号放大的能力。
设备2a:有能量储存能力,不能进行独立的信号产生。例如,设备2a使用反向散射的工作方式,可以使用存储的能量用于DL和/或UL信号放大。
设备2b:有能量存储能力,可以独立的产生信号,例如有主动发送信号的射频(radio frequency,RF)模块。
在上述终端101类型中,设备2b的能力最强,终端成本最高。设备1和设备2a的能力弱,终端成本低。另外,设备1和设备2a由于需要使用反向散射的工作方式,不能主动发送信号,因而其终端可支持的覆盖范围较小,但设备1或设备2a的工作模式的耗电量相比于设备2b的工作模式耗电量要低。
在一些实施例中,终端101例如包括手机(mobile phone)、可穿戴设备、物联网设备、具备通信功能的汽车、智能汽车、平板电脑(Pad)、带无线收发功能的电脑、虚拟现实(virtual reality,VR)终端设备、增强现实(augmented reality,AR)终端设备、工业控制(industrial control)中的无线终端设备、无人驾驶(self-driving)中的无线终端设备、远程手术(remote medical surgery)中的无线终端设备、智能电网(smart grid)中的无线终端设备、运输安全(transportation safety)中的无线终端设备、智慧城市(smart city)中的无线终端设备、智慧家庭(smart home)中的无线终端设备中的至少一者,但不限于此。
在一些实施例中,网络设备102可以包括接入网设备和核心网设备的至少一者。
可选地,接入网设备例如是将终端接入到无线网络的节点或设备,接入网设备可以包括5G通信系统中的演进节点B(evolved NodeB,eNB)、下一代演进节点B(next generation eNB,ng-eNB)、下一代节点B(next generation NodeB,gNB)、节点B(node B,NB)、家庭节点B(home node B,HNB)、家庭演进节点B(home evolved nodeB,HeNB)、无线回传设备、无线网络控制器(radio network controller,RNC)、基站控制器(base station controller,BSC)、基站收发台(base transceiver station,BTS)、基带单元(base band unit,BBU)、移动交换中心、6G通信系统中的基站、开放型基站(Open RAN)、云基站(Cloud RAN)、其他通信系统中的基站、无线保真(wireless fidelity,WiFi)系统中的接入节点中的至少一者,但不限于此。
在一些实施例中,在Ambient-IoT场景中,参考图1b所示,通信系统100还可以包括:连续电磁波节点(Continuous Wave Node,CWN)103、上行接收器(Uplink Receiver,UR)104和能量源节点(Energy Source Node,ESN)105,其中,网络设备102可以作为下行信息发送节点(Downlink Signal Node,DSN)。或者,网络设备102用于实现以下至少一项的功能:DSN,CWN103,UR104,ESN105。
可选地,DSN用于发送下行信息或指示信息。DSN既可以是网络设备102如基站,还可以是中继设备如中继UE。DSN可以发送指示信息给终端101,以触发终端101的上行传输。
可选地,CWN103用于发送连续电磁波(Continuous Wave,CW),终端101可以基于反向散射利用CW发送上行信息。CWN103可实现激励功能,用于设备A和设备B基于反向散射进行上行传输;此外,CW可以作为一种能量源(Energy Source,ES),为终端101提供能量,终端101可以接收CW并储能。
可选地,UR104可以是终端101以外的其他终端或用户设备(user equipment,UE),用于接收Ambient-IoT终端101发送的上行信息。例如,接收终端101基于反向散射通信方式发送的上行信息,或者接收终端101主动传输的上行信息。
可选地,ESN105用于为终端101供能。例如,ESN105为设备B和设备C功能,由于设备A支持的储能能力有限,对于设备A可以不定义CW以外的ES信号。或者,ES也可以用于设备A。
在一些实施例中,参考图1b所示,在该Ambient-IoT通信系统中可以包含4种链路(link),例如包括:用于传输下行信息的链路1,用于接收上行信息的链路2,发送CW的链路3和发送充能信号的链路4。
可选地,链路4可能是受网络控制的,例如网络可以控制ESN105开启或者关闭对终端101的充能。ESN105所供能量可以来自于电磁波或者非电磁波的;此时,ESN105能够与网络调度等功能更好的协同,使得保证终端101充能的同时,尽量不影响终端101的通信。或者,ESN105不受网络控制,或者说,终端101根据终端101能力和实际环境中的能量源,灵活的自行收集能量,例如收集不受网络控制的电磁波或非电磁波能量,没有特定的ESN105节点;此时,可以认为链路4不存在。
可选地,上述实施例中的4种链路中涉及的几个节点如DSN、CWN103、ESN104和UR105可以是分别独立设置的,也可以是同一个节点或设备,或者其中的2个、3个或4个设置为一个节点或设备。例如,在一些实施例中,链路4可以省略或不存在。
在一些实施例中,上述不同节点的功能可以通过一个设备实现或支持,例如,一个设备支持上述多个节点的功能或者支持上述全部节点的功能。或者,一个设备仅对应上述一种功能的节点。网络设备102可以协调上述不同节点如CWN103、ESN104和UR105设备的行为,以支持与终端101的有效通信。
在一些实施例中,图1a和图1b中的设备或节点数量仅为示意,在实际应用中设备或节点均可以采用多个。
在一些实施例中,本公开的技术方案可适用于Open RAN架构,此时,本公开实施例所涉及的接入网设备间或者接入网设备内的接口可变为Open RAN的内部接口,这些内部接口之间的流程和信息交互可以通过软件或者程序实现。

communication system,4G)、)、第五代移动通信系统(5th generation mobile communication system,5G)、5G新空口(new radio,NR)、未来无线接入(Future Radio Access,FRA)、新无线接入技术(New-Radio Access Technology,RAT)、新无线(New Radio,NR)、新无线接入(New radio access,NX)、未来一代无线接入(Future generation radio access,FX)、Global System for Mobile communications(GSM(注册商标))、CDMA2000、超移动宽带(Ultra Mobile Broadband,UMB)、IEEE 802.11(Wi-Fi(注册商标))、IEEE 802.16(WiMAX(注册商标))、IEEE 802.20、超宽带(Ultra-WideBand,UWB)、蓝牙(Bluetooth(注册商标))、陆上公用移动通信网(Public Land Mobile Network,PLMN)网络、设备到设备(Device-to-Device,D2D)系统、机器到机器(Machine to Machine,M2M)系统、物联网(Internet of Things,IoT)系统、车联网(Vehicle-to-Everything,V2X)、利用其他通信处理方法的系统、基于它们而扩展的下一代系统等。此外,也可以将多个系统组合(例如,LTE或者LTE-A与5G的组合等)应用。
由于能量来源的复杂性和多变性,需为Ambient-IoT终端101提供有效或稳妥的供能方法。
图2a是根据本公开实施例示出的一种发送及接收下行信息的方法的交互示意图。如图2a所示,本公开实施例涉及一种发送及接收下行信息的方法,上述方法包括:
步骤S2101,网络设备102向终端101发送下行信息。
在一些实施例中,下行信息包括充能信号,其中,充能信号用于为终端101提供能量。
可选地,充能信号为电磁信号。
在一些实施例中,将充能信号置于下行信息中,网络设备102可通过发送承载充能信号的下行信息为终端101充能,从而为终端101提供受控于网络设备102的无线电磁波能量,提升能量的可靠性和稳妥性。
在一些实施例中,下行信息包括以下至少一种信息类型:
查询Query信令;
重复查询QueryRep信令;
操作命令(command)。
可选地,Query信令还可以称为Query命令,QueryRep信令还可以称为QueryRep命令。其中,Query信令与QueryRep信令用于Ambient-IoT的仓库盘存(inventory)场景,在盘存流程中网络设备102先发送Query信令,再发送QueryRep信令,可能多次下发Query信令或QueryRep信令。该场景中终端101可以是无线射频识别(Radio Frequency Identification,RFID)标签(tag)。
其中,在RFID的仓库盘存业务模式下,对于一个RFID标签,该RFID标签在收到Query信令后,可根据该Query信令中的Q值设置一个随机值计数(counter),counter<=Q。如果counter=0,则RFID标签就可以开始进行反向散射发送上行信息,例如,用于临时表征标签标识(tag ID)的RN16(为16bits的随机数)。如果counter值不为0,则RFID标签不发送信息,并等待接收QueryRep命令,RFID标签每接收到一次QueryRep命令,则counter值减1,直到该counter值减为0时,RFID标签将转换到回复状态并反向散射上行信息。如果进一步收到确认信息ACK,则确认该RFID标签接入成功;否则,如
果收到无效的(invalid)的ACK,或者收到错误RN16的ACK(ACK with erroneous RN16),或者直到设定时段内都没有收到对应的命令,该RFID标签就认为接入不成功。
可选地,操作命令或简称command用于指示终端101的操作,如指示RFID标签写入(write)或接入(access)等。
在一些实施例中,对于上述所有类型的下行信息适用于本实施例中的下行信息结构或下行信息的帧结构,如下行信息均包括充能信号。或者,充能信号和非充能信号位于同一下行信息的帧结构(frame structure)中。
在一示例中,如图2b所示,下行信息包括充能信号和非充能信号,该下行信息的帧结构可包括第一部分和第二部分,其中,第一部分用于承载充能信号,第二部分用于承载非充能信号,第二部分的时域位置在第一部分之前或之后。
可选地,非充能信号可以是其他下行信号。非充能信号可以包括以下至少一项:前导码序列(preamble),控制信息,数据信息等。例如,第一部分承载充能信号,第二部分按时域位置由前至后依次包括preamble、控制信息和数据信息。
在一些实施例中,上述中部分类型的下行信息适用于本实施例中的下行信息结构或下行信息的帧结构,如下行信息包括充能信号,或者包括充能信号和非充能信号。
在一示例中,仍以图2b的示例为例,对于盘存流程中的多次下行信令如Query信令和QueryRep信令,仅Query信令适用于本实施例中下行信息的帧结构,QueryRep信令不适用本实施例中下行信息的帧结构,如Query信令包括充能信号,而QueryRep信令不包括充能信号。
该示例中,网络设备102在发起盘存流程时,可利用首次发送的Query信令对终端101充上足够的能量,在Query信令之后的QueryRep信令中则无需承载充能信号。可选地,若在Query信令之后,终端101仍需充能,可通过充能信号以外的其他方式充能,如通过其他充能信号充能,或者通过其他非无线电的方式充能。
在一些实施例中,充能信号与非充能信号位于同一下行信息的帧结构中,可以通过同一个节点即网络设备102发送该下行信息。结合图1b的结构,本实施例中,网络设备包括ESN105和DSN,即ESN与DSN是同一个节点。
在一些实施例中,下行信息中充能信号的时长、功率或频率等参数可能有多种实施方式。
在一些实施例中,充能信号的发送功率大于阈值,或者,下行信息还包括非充能信号,充能信号的发送功率大于非充能信号的发送功率。
可选地,充能信号为高功率信号,高于阈值或高于其他下行信号,从而提升充能效果。
可选地,下行信息包括多种信息类型,不同信息类型的下行信息中充能信号的发送功率相同。
例如,结合前述盘存流程,下行信息包括多次下行信令如Query信令与QueryRep信令两种类型,二者具有相同功率的充能信号。或者,下行信息包括Query信令与操作command两种类型,二者具有相同功率的充能信号。或者,下行信息包括Query信令、QueryRep信令与操作command三种类型,三者具有相同功率的充能信号。
可选地,下行信息包括多种信息类型,不同信息类型的下行信息中充能信号的发送功率不同,其中,信息类型与发送功率具有映射关系。
例如,结合前述盘存流程,下行信息包括Query信令、QueryRep信令与操作command三种类型,三者分别具有不同功率的充能信号。通过映射关系可分别确定每一种下行信息对应的发送功率,如Query信令对应第一发送功率的充能信号,QueryRep信令对应第二发送功率的充能信号,操作command对应第三发送功率的充能信号。
在一些实施例中,充能信号的持续时长大于或等于第一时长,第一时长为网络设备配置的或协议定义的终端充能所需的时长。
可选地,该持续时长能够满足终端101充能的需求,以使终端101在接收充能信号的过程中可以获得足够的能量。可选地,第一部分的长度大于或等于该第一时长。
可选地,下行信息包括多种信息类型,不同信息类型的下行信息中持续时长相同。
例如,持续时长记为T。结合前述盘存流程,下行信息包括Query信令、QueryRep信令与操作command三种类型,三者的持续时长具有相同T。或者,下行信息包括Query信令与操作command两种类型,二者的持续时长具有相同T。
可选地,下行信息包括多种信息类型,不同信息类型的下行信息中充能信号的持续时长不同,其中,信息类型与持续时长具有映射关系。
例如,结合前述盘存流程,下行信息包括Query信令、QueryRep信令与操作command三种类型,三者的持续时长不同。
再例如,结合前述盘存流程,下行信息包括Query信令与操作command两种类型,二者的持续时长不同。如Query信令中充能信号的持续时长为T1,操作command中充能信号的持续时长为T2,其中,T1>T2。
在一些实施例中,充能信号的频率包括单个频点或多个频点。
可选地,充能信号可以是单频点信号,如充能信号为在频点f0的单频点信号。
可选地,充能信号可以是多频点信号,如充能信号包括在频点f0、f1、f2和f3的多个单频点上的信号。其中,若在某个频点上发生了信道深衰,充能信号的其他频率部分的能量还能继续为终端101充电。例如,对于包括f0、f1、f2和f3多个单频点信号的充能信号,如果在f0频率点上发生了信道深衰,还可以在f1、f2和f3上传输充能信号。
在一些实施例中,充能信号的频域带宽为第一值。
可选地,充能信号具有设定的频域带宽。如,充能信号为带宽为W的带宽信号。
可选地,在充能信号的带宽范围内,若某个频率范围上发生了信道深衰,充能信号的其他频率范围部分的能量还能继续为终端101充电。例如,对于带宽为W充能信号,如果在f4~f5频率范围发生了深衰,充能信号中在f4~f5频率范围之外的部分还可以继续为终端101充电。
可选地,非充能信号的频域带宽为第二值,第一值与第二值相同或不同。例如,结合图2b所示,充能信号的频域带宽与下行信号的频域带宽可以相同或者不同。
在一些实施例中,第一值小于第二值,即充能信号的频域带宽可以小于非充能部分的带宽。
可选地,结合前述实施例,充能信号可以是高功率信号,如充能信号的发送功率相对于非充能信号的发送功率较高,从而充能信号使用较小的频域带宽,可以减小对相邻频率通信信号的影响。
在一些实施例中,终端101接收网络设备102的下行信息。
步骤S2102,终端101存储下行信息提供的能量。
在一些实施例中,本实施例的终端101可以是Ambient-IoT终端。
在一些实施例中,终端101通过接收下行信息中的充能信号,获得无线电磁波能量,终端101将能量存储起来用于信息接收、发送等。
在一些实施例中,终端101可以根据下行信息的类型,执行对应的操作。
可选地,结合前述盘存流程,终端101可根据Query信令和QueryRep信令,确定是否执行上行发送。
可选地,终端101可根据操作命令的指示,执行对应的write或access操作。
在一些实施例中,终端101还可以根据下行信息中非充能信号的部分,执行对应操作。
可选地,终端101可以根据preamble进行同步。
可选地,终端101可以根据数据信息获知网络设备102指示的操作,并执行对应的操作。
在一些实施例中,终端101可基于反向散射方式进行通信。反向散射(backscattering)或反向散射通信(Backscatter Communications)是利用射频信号反向散射原理的极低功耗的调制与传输技术,是实现万物智联的手段。在反向散射通信中,射频信号如电磁波被终端101接收,终端101内部电路通过负载阻抗调制等方式在入射电磁波的基础上调制待传输的信息,然后将调制后携带信息的电磁波发送出去。调制信息的方式可以有多种,移幅键控法(Amplitude Shift Keying,ASK)、移频键控法(Frequency-shift keying,FSK)或移相键控法(phase-shift keying,PSK)等。
在一些实施例中,对于使用反向散射方式的终端101,工作流程可以包括:网络设备102给终端101发送下行指令(如Query信令或QueryRep信令),终端101收到下行指令后,向网络设备102发送对应的响应(response)或者进行对应的操作。
可选地,终端101在向UR104发送数据的同时,需要能量源如CWN103为其提供可供用于反射的CW(即需要链路3)。其中,CW一般是恒定幅度的。其中,终端101反射出的电磁波的频率与CW的频率可以完全相同也可以存在一些偏移(offset),其offset大小与终端101的硬件特性有关。例如,offset可能是一个固定的值,或者,若终端101硬件支持,offset也有可能支持多个固定值,还有可能是可以动态调整的值。
在一些实施例中,对于Ambient-IoT终端101,一种频率资源利用的方式是将可用频谱划分为多个子信道,每个子信道占据固定的带宽,子信道之间频域正交。终端101可以被网络指示使用其中的一个或者多个子信道传输数据,也可以通过某种算法选择一个或者多个子信道传输数据。对于使用反向散射方式的终端101,其天线的工作带宽比较宽,例如数十兆赫(Mhz)。如果CWN103在终端101工作带宽范围内的多个频率点上发射CW,那么终端101将接收到在多个频率点上的CW,并对这多个CW进行反向散射,也即终端101没有仅反射其选择特定子信道的CW的能力。终端101能够使用哪个上行子信道进行
上行发送实际上取决于CW的频率和offset的能力。
在一些实施例中,对于不同类型的终端101,其电路系统架构可能不同。
在一示例中,若终端101为设备1(device1),其电路系统架构可参考图2c所示。该示例中,终端101可以包括时钟发生器(Clock generator)、逻辑电路(Base Band logics,BB logics)和存储器(Memory),还包括天线,用于充能的链路,用于上行发送的链路和用于下行接收的链路。
其中,逻辑电路可以包括解码器(Decoder)、控制器(Controller)和编码器(Encoder)。

在另一示例中,若终端101为设备2a(device2a),并具有RF接收器(receiver),其电路系统架构可参考图2d所示。该示例中,终端101可以包括时钟发生器、逻辑电路和存储器,还包括天线,用于充能的链路,用于上行发送的链路和用于下行接收的链路。
其中,逻辑电路可以包括解码器、控制器和编码器。
用于充能的链路至少可以包括以下电路结构:匹配网络,RF能量采集器,PMU、储能单元和能量采集器(射频除外的other than RF)等。
用于下行接收的链路至少可以包括以下电路结构:匹配网络,RF BPF,低噪声放大器(Low Noise Amplifier,LNA),RF包络检波器,基带放大器(Base Band Amplifier,BB AMP),BB LPF,以及比较器(Comparator)或模数转换器(N-比特ADC)等。
用于上行发送的链路至少可以包括以下电路结构:反射放大器(Reflection Amplifier),反向散射调制器,和大型移频器(Large Frequency Shifter);其中,反向散射调制器可用于阻抗切换。

本公开实施例的方法中,提供一种在ambient IoT网络中进行无线充能的方法,以保证device能够有足够的能量去收发信息。可选地,device对应于前述实施例中的终端101。为便于理解本公开实施例,以下列举一些示例:
示例一:
提供用于网络设备到device的信息发送的帧结构设计,并将充能信号置于帧结构中。
可选地,如图2b所示,该帧结构包含充能信号部分+其他下行信号部分。
可选地,其他下行信号部分,可以由preamble,下行控制信息和数据信息等构成。
示例二:
基于示例一,充能信号部分包含充能信号,用于为device进行无线充能。充能信号可以是高功率信号,例如,其发送功率高于其他下行信号。
示例三:
基于示例一或示例二,充能信号部分的时长为T,以满足为device充能的需求。
示例四:
基于以上任一示例,充能信号的频率可以是单频点信号,例如为在频点f0的单频点信号。
示例五:
基于以上任一示例,充能信号可以是多频点信号,例如在频点f0/f1/f2/f3的多个单频点上的信号。还可以是一个具有一定带宽的信号,例如带宽为W的带宽信号。
可选地,如果在某个频率/频率范围上上发生了信道深衰,充能信号的其他频率/频率范围部分的能量还能继续围device充电。例如,对于在频点f0/f1/f2/f3的多个单频点上的充能信号,如果在f0频率点上发生了信道深衰,则还可以在f1/f2/f3上传输充能信号。再例如,对于带宽为W充能信号,如果在f4~f5频率范围发生了深衰,充能信号中在f4~f5频率范围之外的部分还可以继续为device充能。
示例六:
基于以上任一示例,充能信号和其他下行信号是同一个节点发出来的,在同一个帧结构之中,也即ESN与DSN是同一个节点。
示例七:
基于以上任一示例,该帧结构应用于DSN与device的所有类型下行信号的下行发送中。
可选地,对于不同类型的下行信号,有相同的T。例如:盘存流程中的多次下行信令(Query,QueryRep),用于向device发送操作指令的command(例如write、access等)都有相同的T。
可选地,对于不同类型的下行信号,有不同的T。例如:盘存流程中的多次下行信令(Query,QueryRep),用于向device发送操作指令的command(例如write、access等)有不同的T。
可选地,对于不同类型的下行信号,有相同的充能信号功率。例如:盘存流程中的多次下行信令
(Query,QueryRep),用于向device发送操作指令的command(例如write、access等)都有相同的充能信号功率。
可选地,对于不同类型的下行信号,有不同的充能信号功率。例如:盘存流程中的多次下行信令(Query,QueryRep),用于向device发送操作指令的command(例如write、access等)有不同的充能信号功率。
示例八:
基于以上任一示例,该帧结构仅应用于DSN与device的部分类型下行信号的下行发送中。
可选地,对于盘存流程中的多次下行信令(Query,QueryRep),只在Query信息的帧中使用,不在QueryRep的帧中使用。也即网络侧在发起inventory流程时,在首次发送Query信令时,即可将device充上足够的电量,在此后的queryrep信令中无需再增加充能信号的帧结构。但这并不意味着Device不能通过帧结构之外的信号充能,或者通过其他非无线电的方式充能。
可选地,在应用该帧结构的部分类型下行信号中,充能信号的时长T也可相同或者不相同。例如在包含Query信息的帧中,充能信号的时长为T1,在包含下行command的帧中充能信号时长为T2,T1>T2。
