- Backscatter communication is a low-power modulation and transmission method that utilizes the principle of backscattering radio frequency signals.
- Backscatter communication is a means to achieve the Internet of Things.
- the passive node such as the first device 101, adjusts the matching between the receiving antenna and impedance according to the information to be transmitted, enhancing the reflection of the incident radio frequency signal, and modulating the sensed data it acquires onto the reflected signal to complete the data transmission.
- backscatter communication does not require complex radio frequency structures, reducing the use of devices such as power amplifiers, high-precision crystal oscillators, duplexers, and high-precision filters, and it also does not require complex baseband processing. Therefore, it can simplify terminal design and significantly reduce the cost of terminal nodes.
- the receiver sends a radio frequency excitation signal to activate a passive node.
- the receiver if an RFID reader, corresponds to network device 102; the passive node, if an RFID tag, corresponds to the first device 101.
- the tag uses backscatter communication to modulate its own information onto the radio frequency signal.
- the reader receives the reflected signal from the passive tag and demodulates it to achieve information transmission.
- RFID communication suffers from the following drawbacks: the wireless signal experiences double-path fading, resulting in significant path loss, short effective communication distance, and therefore limited coverage; it also requires single-channel transmission; strict tag alignment is necessary; and there is no power control. Therefore, it is necessary to integrate 3GPP communication technologies to improve the wireless communication performance of RFID technology in passive Internet of Things (IoT) applications.
- IoT Internet of Things
- commands are divided into three categories: tag selection, inventory, and access. Among them:
- the selection commands include the Select command and the Challenge command.
- Inventory commands include: Query, QueryAdjust, QueryRep, ACK, and NAK.
- Access commands include: a random number request (Req_RN) command, a read command, a write command, a kill command, and a lock command; optionally, they may also include: an access command, a block write command, and a block erase command.
- Req_RN random number request
- each tag that meets the set criteria and is selected After receiving a valid Query command, each tag that meets the set criteria and is selected generates a random number. Each tag with a random number of zero will generate an echo, such as sending back a temporary password RN16, which is a 16-bit random number, and will move to the Reply state; other tags can change certain attributes and flags to exit the group of tags with zero, which helps to reduce duplicate identification.
- RN16 temporary password
- each tag After receiving a valid QueryAdjust command, each tag generates a new random number, and other behaviors are the same as the Query command.
- Only unique tags can receive a valid ACK command.
- the tag Upon receipt, the tag sends back the contents of the EPC area according to the Electronic Product Code (EPC) communication protocol.
- the ACK command can use either RN16 or Handle, where Handle is a temporary 16-bit random number representing the tag's identity.
- tags in the Ready and Killed states retain their original states, while tags in other states transition to the Arbitrate state.
- the different states of a tag are shown in Figure 1h.
- the identification and access activation operations for a specific tag can be completed.
- the network side After obtaining the EPC, the network side identifies a certain tag. Before initiating the access command operation for that tag, the network side requests a new random value, Handle, from the tag. Subsequent communication uses the Handle to identify the tag.
- RFID communication conforms to the half-duplex EPC protocol, allowing one reader or one tag to send a signal in a single transmission.
- the reader and tag do not send signals simultaneously; different tags operate serially.
- Ambient IoT concurrent communication needs to be considered, where multiple tags and the network side can perform one-to-one operations simultaneously, such as access commands.
- embodiments of this disclosure provide a communication method.

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。
可以理解的是,本公开实施例描述的通信系统是为了更加清楚的说明本公开实施例的技术方案,并不构成对于本公开实施例提供的技术方案的限定,本领域普通技术人员可知,随着系统架构的演变和新业务场景的出现,本公开实施例提供的技术方案对于类似的技术问题同样适用。
下述本公开实施例可以应用于图1a至图1f所示的通信系统100、或部分主体,但不限于此。
图1a至图1f所示的各主体是示例,通信系统可以包括图1a至图1f中的全部或部分主体,也可以包括图1a至图1f以外的其他主体,各主体数量和形态为任意,各主体之间的连接关系是例示,各主体之间可以不连接也可以连接,其连接可以是任意方式,可以是直接连接也可以是间接连接,可以是有线连接也可以是无线连接。
本公开各实施例可以应用于长期演进(Long Term Evolution,LTE)、LTE-Advanced(LTE-A)、LTE-Beyond(LTE-B)、SUPER 3G、IMT-Advanced、第四代移动通信系统(4th generation mobile 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。
为满足垂直领域日益增长的需求,已有的低功率广域(Low Power Wide Area,LPMA)技术,如机器类型通信(Machine Type Communication,MTC)、窄带物联网(Narrow Band Internet of Things,NB-IoT)、低能力(Reduced Capability,RedCap)等,能够实现低成本、低功耗和大规模连接。但是,仍无法解决以下需求:首先,由传统电池驱动的装置不适用,例如在极端环境条件下(例如高压、极高/低温、潮湿环境);其次,需要免维护设备(例如,无需更换设备的传统电池);最后,需要超低的复杂性、非常小的器件尺寸或形状因子(例如mm的厚度)、更长的寿命周期等。而支持环境电力或环境供能的物联网可以满足以上需求。
低功耗物联网通信芯片如蓝牙低能耗(Bluetooth Low Energy,BLE)远距离无线电(Long Range Radio,LoRa)或NB-IoT,其收发功耗都在数十毫瓦甚至数百毫瓦级别。而结合前述实施例的描述,环境能量采集获取能量仅有微瓦级,从环境获取能量可驱动感知节点如第一设备101进行数据传输和无线通信,需要能够使通信能耗下降至数十微瓦甚至十微瓦以下的无线通信技术。
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,由于射频信号如电磁波到达物体表面时一部分会被反射,作为发送节点的无源节点如第一设备101按照拟发送信息调整接收天线和阻抗之间的匹配,增强对入射射频信号的反射,并将自身获取的感知数据调制到该反射信号上,完成对数据的发送。相对于其他通信技术,反向散射通信无需复杂的射频结构,减少功率放大器、高精度晶振、双工器、高精度滤波器等器件使用,也不需要复杂的基带处理,因此,能够简化终端设计,大幅降低终端节点成本。
在应用反向散射通信的无线射频识别(Radio Frequency Identification,RFID)系统中,如图1g所示,接收机发送射频激励信号,激活无源节点。其中,接收机如为RFID阅读器(Reader),对应于网络设备102;无源节点如为RFID电子标签(tag),对应于第一设备101。电子标签利用反向散射通信将自身信息调制到该射频信号上,阅读器接收到无源电子标签的反射信号并进行解调,实现信息传输。RFID的通信过程中存在以下缺点:无线信号会经历往返的双重路径衰落,路径损耗大,有效通信距离短,因此覆盖距离小;并且需要单信道传输;需要严格对准标签;无功率控制等。需要融合3GPP通信技术改善RFID技术在无源物联网方面的无线通信性能。
在RFID通信系统中,如图1h所示,从使用功能上看分为标签选取(Select),盘存(Inventory)和存取(Access)三类命令。其中:
选取命令包括:即选取(Select)命令和盘问(Challenge)命令。
盘存命令包括:查询(Query)命令,查询调整(QueryAdjust)命令,重复查询(QueryRep)命令,确定(ACK)命令,否定(NAK)命令。
存取命令包括:随机数请求(Req_RN)命令,读取(Read)命令,写入(Write)命令,终止(Kill)命令,锁定(Lock)命令;可选地,还可以包括:存取(Access)命令,块写入(BlockWrite)命令,块消除(BlockErase)命令。
结合图1i所示的盘存和存取示例,盘存和存取中的命令应用实例可以包括:
(1)标签收到有效Query命令后,符合设定标准被选择的每个标签产生一个随机数。随机数为零的每个标签将产生回响,如发回临时口令RN16,RN16为一个16比特(bit)随机数,并转移到应答(Reply)状态;其他标签可以改变某些属性和标志,退出为零的标签群,有利于减少重复识别。
(2)标签收到有效QueryAdjust命令后,各标签分别新产生一个随机数,其他行为同Query命令。
(3)标签收到有效QueryRep命令后,对标签群中的每个标签原有的随机数减一,其他行为同Query命令。
(4)仅单一化的标签才能收到有效ACK命令,收到后依据电子产品代码(Electronic Product Code,EPC)通信协议发回EPC区中的内容。其中,ACK命令可以使用上述RN16或句柄Handle,句柄Handle为一个临时代表标签身份的16-bit随机数。
(5)标签收到有效NAK命令后,处于Ready状态、Killed状态的标签保持原状态,处于其它状态的标签都转到Arbitrate状态。其中,标签的几种状态(state)如图1h所示。
其中,基于RN16可完成针对某个具体标签的识别和开启接入操作,在获取EPC之后网络侧识别了某个标签。网络侧在针对该标签开启access命令操作之前,向标签索要了新的随机值Handle,随后的通信基于Handle来标识一个标签。
此外,RFID通信符合半双工的EPC协议,在一次传输中,允许一个阅读器发送信号或一个标签发送信号。阅读器和标签不会同时发送信号,不同的标签串行工作。在ambient IOT中需要考虑并发通信,在同一个时刻存在多个标签和网络侧进行1对1的操作,如access command类似命令的操作。
为提升通信性能,以及有效调度环境物联网设备,本公开实施例提供一种通信方法。
图2a是根据本公开实施例示出的一种通信方法的交互示意图。如图2a所示,本公开实施例涉及一种通信方法,上述方法包括:

在第一种可能的实施方式中,第一信息包括以下至少一项:
第一时长;
频率信息。
可选地,第一信息可以包括与第一时长相关的信息。
可选地,第一信息可以包括与频率信息相关的信息。
可选地,第一时长为第一设备101不期待与网络设备102通信的时长。该通信可以是上行通信或下行通信,例如,第一时长为第一设备101不期待向网络设备102发送上行信息如UL命令的时长,和/或,第一时长为第一设备101不期待接收网络设备102的下行(Downlink,DL)信息如DL命令的时长。
可选地,第一时长为相对时间信息,例如第一时长的起始时间为第一信息的发送时间。
可选地,频率信息为第一设备101期待的与网络设备102进行下一次通信的频率信息,下一次通信

在一示例中,在第一设备101每一次进行上行发送之前,网络设备102通过DL信令或DL命令为第一设备101分配该次上行发送的资源,第一设备101基于DL信令的配置进行上行发送。其中,分配上行发送的资源可以包括分配上行发送的频率信息,或分配上行发送的时间信息等。
该示例中,以第一设备101与网络设备102的本次通信(记为第N次)为第一设备101发送第一信息为例,下一次通信可以是指本次通信之后的下行接收,如网络设备102通过第N+1次下行发送DL信令为第一设备101的N+1次上行发送分配资源,第一设备101接收下行信息即接收该DL信令。或者,该示例中,下一次通信可以是指本次通信之后的上行发送,如第一设备101的N+1次发送上行信息如UL命令。
在一些实施例中,频率信息为第一设备101期待的下一次接收下行信息(如DL命令)的第一频率信息,或第一设备101期待的下一次发送上行信息(如UL命令)的第二频率信息。

可选地,第一设备101上报的循环移位值用于依据参考信道号确定第一设备101期待的信道号。如以下两种示例:
在一示例中,在频率信息为第一频率信息时,下一次接收下行信息所在的信道号为(n+k)mod M,其中,n为发送第一信息的信道号,k表示循环移位值,M表示总信道数量。Mod表示求余运算。
该示例中,依据循环移位值k和当前上行发送的信道号n,确定第一设备101期待的或建议的下行接收的信道号。例如结合前述实施例的描述,当前上行发送为第N次通信,依据k和第N次上行发送的信道号n,确定第N+1次网络设备102下行发送或第一设备101下行接收的信道号。其中,M可以等于20。
在另一示例中,在频率信息为第二频率信息时,下一次发送上行信息所在的信道号为(n+k)mod M,其中,n为发送第一信息之后且下一次发送上行信息之前接收到的下行信息的信道号,k表示循环移位值,M表示总信道数量。
该示例中,依据循环移位值k和当前上行发送之后最近一次下行接收的信道号n,确定第一设备101期待的或建议的下一次上行发送的信道号。例如结合前述实施例的描述,当前上行发送为第N次通信,依据k和网络设备102的第N+1次下行发送的信道号n,确定第N+1次上行发送的信道号。其中,M可以等于20。

在一些实施例中,第二时长可以是通过协议定义的,或者与网络设备102预先约定好的。例如,第二时长是网络设备102预先指示给第一设备101的,或者是第一设备101预先向网络设备102上报的。
在第三种可能的实施方式中,第一信息可以包括第一种可能的实施方式中的至少一项参数,和第二种可能的实施方式中的至少一项参数。例如,第一信息包括以下至少一项:

本公开实施例中,提供一种在tag通信过程中,基于tag提供的辅助参数来给tag做资源分配和调度的方法。该实施例中,tag或终端对应于前述实施例的第一设备101,网络侧对应前述实施例的网络设备102。为便于理解本公开实施例,以下列举一些示例:
示例一:
终端发送UL命令,UL命令中包含如下信息:
可选例(Option 1):时间信息。
其中,时间信息为相对时间信息,即从tag发送UL命令开始,启动一个定时器T1,在定时器超时之前,tag不期待接收任何的DL命令和/或发送任何UL命令。在T1运行期间,tag可以接收供能信息补充电力,也可以什么都不做,取决于tag实现。对于网络侧来说,接收到该UL命令,则网络侧针对该tag启动定时器,定时器运行期间,不发送任何针对该tag的下行命令。
Option 2:频率信息1。
其中,频率信息1用于tag建议喜欢的下次接收DL命令的频率信息。频率信息1是一个绝对的信道号,例如在中国RFID的国内标准中,系统带宽为5MHz,250KHz一个子信道,总共可以有20个子信道。从低频到高频子信道标号为0~19。可选地,频率信息1还可以是一个循坏移位值,例如k,则此时下次接收DL命令的信道号为(发送此时UL命令的信道号n+k)mod总的子信道号,例如20。
Option 3:频率信息2。
其中,频率信息2用于tag建议喜欢的下次发送UL命令的频率信息。频率信息2是一个绝对的信道号,例如在中国RFID的国内标准中,系统带宽为5MHz,250KHz一个子信道,总共可以有20个子信道。从低频到高频子信道标号为0~19。可选地,频率信息2还可以是一个循坏移位值,例如k,则此时下次发送UL命令的信道号为(接收DL信令的信道号n+k)mod总的子信道号,例如20。此处发送UL信令,是基于接收DL信令中的资源分配。
示例二:
Tag向网络侧发送指示信息,指示信息用于指示tag需要搜集能量,同时tag还可以给出预约的时间长度,该长时间长度可以协议约定或者事先预定好的。例如,事先约定好可以是:事先网络指示给tag,或者事先tag指示给网络。
网络侧回复tag,指示tag可以去搜集能得时间长度。
时间从tag接收到指令开始,在该时间长度范围内,网络侧不发送下行命令给tag。
示例三:
网络侧给tag下发一个时间长度信息,时间长度信息用于指示tag在该时间端内,不需要监听网络侧。该时间长度可以从接收到携带该时间长度的DL指令开始。
本公开实施例中,基于tag提供的辅助参数来给tag做资源分配和调度。例如tag在一个UL发送之后,需要采集供能信号,或者tag在DL发送和UL发送的频偏差异不能太大,或者tag在通信过程中进行节能,在某段时间内不期待接收DL接收和UL发送。辅助信息有助于网络侧根据tag的诉求进行对tag进行调度,使得tag的通信性能达到最佳。
