  • the transmission power of network equipment is generally not too large. For example, in the ISM frequency band where RFID works, the maximum transmission power is 30dBm. Therefore, considering the radio propagation loss in space, the transmission distance of passive zero-power devices is generally in the range of 10m to tens of meters.
  • Semi-passive zero-power devices have the potential to significantly extend communication distances. This is because semi-passive zero-power devices can use energy harvesting modules to collect radio waves, so they can continuously obtain radio energy and store it in energy storage units. After the energy storage unit obtains enough energy, it can drive low-power circuits to work for forward link signal demodulation and reverse link signal modulation. Therefore, at this time, the semi-passive zero-power device is equivalent to an active terminal, and its downlink coverage depends on the receiver sensitivity of the downlink signal (usually far below the RF energy harvesting threshold). Based on current technology, the energy harvesting module can harvest energy and input electrical energy into the energy storage unit when the received radio signal strength is not less than -30dBm.

  • the energy harvesting threshold such as -30dBm.
  • the received radio signal strength is relaxed from -20dBm to -30dBm, so a 10dB link budget gain can be obtained, so the downlink coverage can be improved by more than 3 times.
  • semi-passive zero-power devices While improving the forward link coverage, semi-passive zero-power devices also face the problem of reduced charging efficiency. As the received signal strength decreases, the energy that can be collected and stored by the energy harvesting module is greatly reduced. For example, when the received signal strength is -30dBm, that is, 1 microwatt, the energy that can be collected and stored is far less than 1 microwatt (the energy harvesting efficiency is greatly reduced).
  • the low-power circuit of the zero-power device may need to consume an average power of 10uW. Therefore, for semi-passive zero-power devices, a longer period of energy harvesting is required to support shorter-term communication. For example, for sensor devices, data reading, data reporting, and data reception all require a certain amount of energy.
  • the peer device does not know the energy storage status of the zero-power device. Whether the zero-power device is in a power-off state or an energy harvesting state, it cannot communicate with other devices. Here it is assumed that the zero-power device cannot achieve energy harvesting and communication at the same time. Therefore, due to the uncertainty of the state of the zero-power device, other devices communicating with it cannot determine the time when communication can be carried out. If blind transmission and blind reception are adopted, power and resources will be wasted. Therefore, how to ensure communication between zero-power devices and other devices is an urgent problem to be solved.

一、零功耗通信
近年来,零功耗设备的应用越来越广泛。一种典型的零功耗设备是射频识别(Radio Frequency Identification,RFID),它是利用无线射频信号空间耦合的方式,实现无接触的标签信息自动传输与识别的技术。RFID标签又称为“射频标签”或“电子标签”。根据供电方式的不同来划分的电子标签的类型,可以包括有源电子标签,无源电子标签和半无源电子标签。有源电子标签,又称为主动式电子标签,是指电子标签工作的能量由电池提供,电池、内存与天线一起构成有源电子标签,不同于被动射频的激活方式,在电池更换前一直通过设定频段发送信息。无源电子标签,又称为被动式电子标签,其不支持内装电池,无源电子标签接近读写器时,标签处于读写器天线辐射形成的近场范围内电子标签天线通过电磁感应产生感应电流,感应电流驱动电子标签芯片电路。芯片电路通过电子标签天线将存储在标签中的标识信息发送给读写器。半主动式电子标签继承了无源电子标签体积小、重量轻、价格低、使用寿命长的优点,内置的电池在没有读写器访问的时候,只为芯片内很少的电路提供 电源,只有在读写器访问时,内置电池向RFID芯片供电,以增加标签的读写距离较远,提高通信的可靠性。
最基本的RFID系统是由电子标签(TAG)和读写器(Reader/Writer)两部分构成。其中,电子标签由耦合组件及芯片构成,每个电子标签都有独特的电子编码,放在被测目标上以达到标记目标物体的目的。读写器不仅能够读取电子标签上的信息,而且还能够写入电子标签上的信息,同时为电子标签提供通信所需要的能量。电子标签进入电磁场后,接收读写器发出的射频信号,无源电子标签或者被动电子标签利用空间中产生的电磁场得到的能量,将电子标签存储的信息传送出去,读写器读取信息并且进行解码,从而识别电子标签。
基于零功耗设备的通信简称零功耗通信。
如图2所示,一种典型的零功耗通信系统(例如RFID系统)包括网络设备(如RFID系统的读写器)和零功耗设备(例如如电子标签)。网络设备用于向零功耗设备发送无线供能信号,下行通信信号以及接收零功耗设备的反向散射信号。可选地,零功耗设备包括能量采集模块,反向散射通信模块以及低功耗计算模块。此外,零功耗设备还可具备一个存储器或传感器,用于存储一些基本信息(如物品标识等)或环境温度、环境湿度等传感数据。
例如,能量采集模块可以采集空间中的无线电波携带的能量(图2中所示为网络设备发射的无线电波),用于驱动零功耗设备的低功耗计算模块和实现反向散射通信。零功耗设备获得能量后,可以接收网络设备的控制命令并基于控制信令基于反向散射的方式向网络设备发送数据。所发送的数据可以为零功耗设备自身存储的数据(如身份标识或预先写入的信息,如商品的生产日期、品牌、生产厂家等)。零功耗设备也可以加载各类传感器,从而基于零功耗机制将各类传感器采集的数据上报。
以下,对零功耗通信中的关键技术进行说明。
1、射频能量采集(RF Power Harvesting)
如图3所示,射频能量采集模块基于电磁感应原理实现对空间电磁波能量的采集,进而获得驱动零功耗设备工作所需的能量,例如用于驱动低功耗解调以及调制模块、传感器以及内存读取等。因此,零功耗设备无需传统电池。
2、反向散射通信(Back Scattering)
如图4所示,零功耗设备接收网络设备发送的载波信号,并对所述载波信号进行调制,加载需要发送的信息并将调制后的信号从天线辐射出去,这一信息传输过程称之为反向散射通信。反向散射和负载调制功能密不可分。负载调制通过对零功耗设备的振荡回路的电路参数按照数据流的节拍进行调节和控制,使零功耗设备阻抗的大小等参数随之改变,从而完成调制的过程。负载调制技术主要包括电阻负载调制和电容负载调制两种方式。在电阻负载调制中,负载并联一个电阻,该电阻基于二进制数据流的控制接通或断开,如图5所示。电阻的通断会导致电路电压的变化,因此实现幅度键控调制(ASK),即通过调整零功耗设备的反向散射信号的幅度大小实现信号的调制与传输。类似地,在电容负载调制中,通过电容的通断可以实现电路谐振频率的变化,实现频率键控调制(FSK),即通过调整零功耗设备的反向散射信号的工作频率实现信号的调制与传输。
可见,零功耗设备借助于负载调制的方式,对来波信号进行信息调制,从而实现反向散射通信过程。因此,零功耗设备具有显著的优点:
(1)不主动发射信号,因此不需要复杂的射频链路,如PA、射频滤波器等;
(2)不需要主动产生高频信号,因此不需要高频晶振;
(3)借助反向散射通信,终端信号传输不需要消耗终端自身能量。
3、编码技术
零功耗设备传输的数据,可以用不同形式的代码来表示二进制的“1”和“0”。无线射频识别系统通常使用下列编码方法中的一种:反向不归零(NRZ)编码、曼彻斯特(Manchester)编码、单极性归零编码、差动双相(DBP)编码、差动编码、脉冲间隔编码(PIE)、双向空间编码(FM0)、米勒(Miller)编码利差动编码等。通俗来说,不同的编码技术是采用不同的脉冲信号表示0和1。
在一些场景中,基于零功耗设备的能量来源以及使用方式,可以将零功耗设备分为如下类型:
1、无源零功耗设备
零功耗设备(如RFID系统的电子标签)不需要内装电池,零功耗设备接近网络设备(如RFID系统的读写器)时,零功耗设备处于网络设备天线辐射形成的近场范围内。因此,零功耗设备天线通过电磁感应产生感应电流,感应电流驱动零功耗设备的低功耗芯片电路。实现对前向链路信号的解调,以及反向链路(或称反射链路)的信号调制等工作。对于反向散射链路,零功耗设备使用反向散射实现方式进行信号的传输。
可以看出,无源零功耗设备无论是前向链路还是反向链路都不需要内置电池来驱动,是一种真正 意义的零功耗设备。
无源零功耗设备不需要电池,射频电路以及基带电路都非常简单,例如不需要低噪放(LNA),功放(PA),晶振,模数转换器(Analog-to-Digital Converter,ADC)等器件,因此具有体积小、重量轻、价格非常便宜、使用寿命长等诸多优点。
2、半无源零功耗设备
半无源零功耗设备自身也不安装常规电池,但可使用RF能量采集模块采集无线电波能量,同时将采集的能量存储于一个储能单元(如电容)中。储能单元获得能量后,可以驱动零功耗设备的低功耗芯片电路。实现对前向链路信号的解调,以及反向链路的信号调制等工作。对于反向散射链路,零功耗设备使用反向散射实现方式进行信号的传输。
可以看出,半无源零功耗设备无论是前向链路还是反向链路都不需要内置电池来驱动,虽然工作中使用了电容储存的能量,但能量来源于能量采集模块采集的无线电能量,因此也是一种真正意义的零功耗设备。
半无源零功耗设备继承了无源零功耗设备的诸多优点,因此具有体积小、重量轻、价格非常便宜、使用寿命长等诸多优点。
3、有源零功耗设备
有些场景下使用的零功耗设备也可以为有源零功耗设备,此类设备可以内置电池。电池用于驱动零功耗设备的低功耗芯片电路。实现对前向链路信号的解调,以及反向链路的信号调制等工作。但对于反向散射链路,零功耗设备使用反向散射实现方式进行信号的传输。因此,这类设备的零功耗主要体现于反向链路的信号传输不需要终端自身功率,而是使用反向散射的方式。
二、蜂窝无源物联网
随着5G行业应用的增加,连接物的种类和应用场景越来越多,对通信终端的成本和功耗也将有更高要求,免电池、低成本的无源物联网设备的应用成为蜂窝物联网的关键技术,充实5G网络链接终端类型和数量,真正实现万物互联。其中无源物联网设备可以基于零功耗通信技术,如RFID技术,并在此基础上进行延伸,以适用于蜂窝物联网。

从载波信号载体上,可以是基站、智能手机、智能网关等。
从频段上,用作载波信号的无线电波可以是低频、中频、高频等。
从波形上,用作载波信号的无线电波可以是正弦波、方波、三角波、脉冲、矩形波等。
此外,该载波信号可以是连续波,也可以是非连续波(即允许一定的时间中断)。
可选地,载波信号可能是3GPP标准中的已有信号。例如SRS,PUSCH、PRACH、PUCCH、PDCCH、PDSCH、PBCH,或者,WIFI信号、蓝牙信号、zigbee信号等。
可选地,载波信号也可以通过新定义信号实现,例如新定义专用产生反向散射信号的载波信号。
需要说明的是,在本申请实施例中,供能信号,调度信号和载波信号可以是同一信号,或者,也可以是不同的信号,例如,供能信号可以作为载波信号,调度信号也可以用作载波信号等。
在实际网络部署中,无源零功耗通信技术面临的一个技术瓶颈是前向链路的覆盖距离受限,主要原因在于前向链路的通信距离受限于到达零功耗设备处的无线信号的信号强度,基于现有的实现工艺,一般零功耗设备需要消耗10uw(微瓦)的功率以驱动低功耗电路。这意味着到达零功耗设备的信号功率至少需要为-20dBm。受限于无线电监管的要求,网络设备的发射功率一般不能太大,例如在RFID工作的ISM频段,最大发射功率为30dBm。因此,考虑到空间的无线电传播损耗,无源零功耗设备的传输距离一般在10m至几十米的范围。
而半无源零功耗设备具有显著扩展通信距离的潜力,这是由于,半无源零功耗设备可以使用能量采集模块收集无线电波,因此可以源源不断获取无线电能量并储存于储能单元中。储能单元获得足够的能量后,可以驱动低功耗电路工作用于前向链路的信号解调以及反向链路的信号调制等操作。因此,此时,半无源零功耗设备就等效于一个有源终端,其下行的覆盖取决于下行信号的接收机灵敏度(通常远低于RF能量采集门限)。基于目前的工艺,能量采集模块可以在接收的无线电信号强度不低于-30dBm时可以进行能量采集并将电能输入到储能单元。因此,半无源零功耗设备的前向链路的覆盖取决于能量采集门限(如-30dBm),相对无源零功耗设备,接收的无线电信号强度从-20dBm放松到-30dBm,因此可以获得10dB的链路预算增益,因此可以提升多于3倍的下行覆盖。
然而,在提升前向链路覆盖的同时,半无源零功耗设备也面临充电效率下降的问题。随着接收信号强度的下降,能量采集模块可采集并储存的能量大幅降低。如,在接收信号强度为-30dBm时,也即1微瓦时,可采集并存储的能量远不及1微瓦(能量采集效率大幅下降)。另一方面,如前所述,零功耗设备的低功耗电路可能需要消耗10uw的平均功率。因此,对于半无源的零功耗设备,需要较长时间的能量采集以支持较短时间的通信。例如,对于传感器设备来说,其进行数据读取、数据上报、接收数据都需要消耗一定的能量。但是,对端设备并不知道零功耗设备的储能状态。无论是零功耗设备处于无电状态还是能量采集状态,都无法与其他设备进行通信。这里假设零功耗设备无法实现能量采集和通信同时进行。因此,由于零功耗设备状态的不确定,与之通信的其他设备无法确定可以进行通信的时间,如果采取盲发送和盲接收的方式,会造成功率和资源的浪费。因此,如何保证零功耗设备和其他设备之间的通信是一项亟需解决的问题。
为便于理解本申请实施例的技术方案,以下通过具体实施例详述本申请的技术方案。以上相关技术作为可选方案与本申请实施例的技术方案可以进行任意结合,其均属于本申请实施例的保护范围。本申请实施例包括以下内容中的至少部分内容。

S210,第一设备根据第一时域资源与第二设备进行通信,所述第一时域资源是预设的时域资源,所述第一设备通过能量采集获得用于通信的能量。
对应地,第二设备根据第一时域资源与第一设备进行通信。

在一些实施例中,所述第一设备不同时进行能量采集和进行通信。
换言之,第一设备不同时处于能量采集状态和通信状态,也即,第一设备处于能量采集状态和通信状态在时间上是分开的。
在一些实施例中,第一设备可以对无线射频信号进行能量采集,该第一设备的接收机通过无线射频信号获取的能量,通常仅用于信号处理(例如信号解调或信号调制)和能量采集中的一种,因此,第一设备不能够同时执行能量采集和通信。
例如,在接收到无线射频信号之前,第一设备需要确定当前可执行的行为是进行信号处理还是能量采集。如果第一设备当前的储能满足信号处理所需的能量,则第一设备可以利用能量进行信息处理,而不进行能量采集,当然第一设备也可以继续进行能量采集。

在一些实施例中,第一时域资源是预设的时域资源。或者说,第一时域资源是预设的用于通信的时域资源。也即,通信的发送端设备和接收端设备均可以获知该第一时域资源,二者对于用于通信的时域资源的理解一致。因此,在本申请实施例中,第一设备和第二设备进行通信时有明确的时域资源,因此,不必采用盲发送和盲接收的方式进行通信,能够降低采用盲发送和盲接收方式造成的功率和资源的浪费。
在一些实施例中,第一时域资源可以理解为基本的时域资源,用于保证第一设备和对等设备之间通信的基本需求。在一个具体实施例中,第二设备是网络设备,在该第一时域资源上,网络设备可以发起与零功耗设备的通信,例如,网络设备可以通过寻呼来触发与第一设备的后续通信;第一设备也可以在第一时域资源上发起与网络设备之间的通信,例如通过随机接入触发与网络设备的后续通信。

在一些实施例中,第一时域资源包括用于所述第一设备进行信号发送的资源和/或用于所述第一设备进行信号接收的资源。
例如,在第一时域资源上,用于第一设备进行信号发送的资源和用于第一设备进行信号接收的资源是时分的。
又例如,第一时域资源既可以用于第一设备进行信号发送又可以用于第一设备进行信号接收。
在一些实施例中,第一时域资源可以是针对不同的第一设备分别进行设置的。

在一些实施例中,第一设备的储能能力可以包括但不限于第一设备的储能容量。
第一设备的储能容量越大,可以认为第一设备在完成储能之后支持的通信时长越长,因此,该第一设备对应的第一时域资源的持续时长也可以设置的较长。
第一设备的能量采集来源的强度越高,可以认为第一设备的能量采集能力(或者说,能量采集效率)越强,执行相同时间的能量采集所能支持的通信时长越长,因此,该第一设备对应的第一时域资源的持续时长也可以设置的较长。

例如,第二设备认为(或者说,假定)第一设备在第一时域资源上处于通信状态,或者说,第二设备可以认为(或者说,假定)第一设备可以在该第一时域资源上进行信号的发送和/或接收,因此,第二设备可以尝试在该第一时域资源上进行信号的接收和/或发送,从而能够降低采用盲发送和盲接收方式造成的功率和资源的浪费。

也就是说,在本申请实施例中,第二设备可以认为(或者说,假定)第一设备在第一时域资源上处于通信状态,从而可以与第一设备进行通信。
应理解,在本申请实施例中,第一时域资源是用于通信的时域资源,但并不表示第一设备和第二设备一定会在该第一时域资源上进行通信(也就是说,第一设备在第一时域资源上并不一定处于通信状态),第一时域资源的设置是为了保证第一设备和第二设备在需要进行通信时有明确的时域资源,而不是采用盲发送和盲接收的方式进行通信。
