Its connection density is compared with the fifth generation communication network ( 5th Generation, 5G). It has been improved by 10-100 times, reaching a connection density of 10-100/ m2 .
其中,蜂窝网络化、低成本、低功耗甚至零功耗、无源化是未来物联网设备发展的主要趋势,但以无源终端为例,考虑到其受限于自身功耗与硬件能力,其通信传输距离大多在10米以下,远远达不到蜂窝化百米覆盖范围的目标,因此,如何实现对如无源终端等物联网设备的有效管理成为当前需要解决的问题。Among them, cellular networking, low cost, low power consumption or even zero power consumption, and passivity are the main trends in the development of IoT devices in the future. However, taking passive terminals as an example, considering that they are limited by their own power consumption and hardware capabilities , the communication transmission distance is mostly below 10 meters, which is far from the goal of cellular coverage of 100 meters. Therefore, how to achieve effective management of IoT devices such as passive terminals has become a current problem that needs to be solved.

基于此,考虑到射频信号、同步信号以及广播信息既可以统一设计也可以独立设计,因此在进行目标信号发送时可以有多重组合形式,如所述目标信号中包括的射频信号、同步信号、广播信息可以通过同一个信号发送,也可以通过不同的信号进行发送,以适应不同的BSC需求。值得注意的是,在本实施例中,BSC设备(或第二设备)可能是无源设备或者半无源设备,能量来源可以是太阳能、热能或者射频能量等,但是BSC设备主要还是利用第一设备提供的目标载波进行反向散射供能的设备。可以理解,目标载波本身也可以作为供能信号。下面结合示例1-示例5,对所述目标信号的发送方式进行说明,内容如下。Based on this, considering that radio frequency signals, synchronization signals and broadcast information can be designed in a unified way or independently, there can be multiple combinations when transmitting target signals, such as radio frequency signals, synchronization signals, broadcast information included in the target signal. Information can be sent via the same signal or via different signals to accommodate different BSC needs. It is worth noting that in this embodiment, the BSC device (or the second device) may be a passive device or a semi-passive device, and the energy source may be solar energy, thermal energy, radio frequency energy, etc., but the BSC device mainly uses the first A device that provides backscatter energy to the target carrier provided by the device. It can be understood that the target carrier itself can also be used as the energy supply signal. The method of sending the target signal will be described below with reference to Example 1 to Example 5. The content is as follows.
示例1Example 1
所述目标信号包括射频信号、同步信号以及广播信息。也就是说,所述目标信号中的射频信号、同步信号、广播信息通过同一个信号进行发送。其中,如图4a所示,射频信号用于给第二设备提供目标载波和供能,同步信号用于第二设备与第一设备同步,广播信息则用于携带第一设备所在组相关的广播信息等。射频信号供能之后,中间无需再发送其他供能信号用于第二设备供能,并且射频信号之后紧跟着同步信号与广播信号,这对第二设备的同步稳定性以及解调性能都有较高的要求。因而,示例1中提供的目标信号发送方式适合于设备能力较强,且能量转化效率高、晶振稳定的第二设备(即BSC设备)。The target signal includes radio frequency signal, synchronization signal and broadcast information. That is to say, the radio frequency signal, synchronization signal, and broadcast information in the target signal are sent through the same signal. Among them, as shown in Figure 4a, the radio frequency signal is used to provide the target carrier and energy supply to the second device, the synchronization signal is used to synchronize the second device with the first device, and the broadcast information is used to carry the broadcast related to the group to which the first device belongs. Information etc. After the radio frequency signal is powered, there is no need to send other power supply signals in the middle to power the second device, and the radio frequency signal is followed by the synchronization signal and the broadcast signal, which is beneficial to the synchronization stability and demodulation performance of the second device. Higher requirements. Therefore, the target signal transmission method provided in Example 1 is suitable for the second device (ie, BSC device) with strong device capabilities, high energy conversion efficiency, and stable crystal oscillator.
示例2Example 2
所述目标信号包括第一信号和第二信号,所述第一信号包括射频信号、同步信号,所述第二信号包括所述广播信息,所述第一信号的发送时间早于
所述第二信号。The target signal includes a first signal and a second signal. The first signal includes a radio frequency signal and a synchronization signal. The second signal includes the broadcast information. The sending time of the first signal is earlier than the second signal.
也就是说,在该示例2中采用的是射频信号、同步信号与广播信息解耦的一种设计。其中如图4b所示,射频信号和同步信号可共同承载在第一信号中,并且作为一种可选的实现方式,还可以在第一信号中携带用于触发第二设备接收第二信号的触发广播接收信号,以用于触发所述第二设备接收所述第二信号。In other words, Example 2 adopts a design in which radio frequency signals, synchronization signals and broadcast information are decoupled. As shown in Figure 4b, the radio frequency signal and the synchronization signal can be carried together in the first signal, and as an optional implementation, the first signal can also carry a signal for triggering the second device to receive the second signal. Triggering the broadcast reception signal is used to trigger the second device to receive the second signal.
基于此,所述第一设备在发送第一信号之后,可等待固定的时间,再发送承载在第二信号中的广播信息。这种设计可以将公共的射频信号和同步信号放在一起,而将广播信息单独承载,从而使得广播信息的设计可以更灵活。另外,第一信号和第二信号之间存在时间间隔,从而使得第二设备有更多的时间进行同步和信号解析;但同时也意味着第二设备需要更高的能量转化效率或储能容量。基于此,示例2中提供的目标信号设计方式适合于半无源BSC或者能量转化效率较高,并且用于同步的晶振稳定的BSC设备。Based on this, after sending the first signal, the first device may wait for a fixed time before sending the broadcast information carried in the second signal. This design can put public radio frequency signals and synchronization signals together, and carry broadcast information separately, making the design of broadcast information more flexible. In addition, there is a time interval between the first signal and the second signal, which allows the second device to have more time for synchronization and signal analysis; but it also means that the second device requires higher energy conversion efficiency or energy storage capacity. . Based on this, the target signal design method provided in Example 2 is suitable for semi-passive BSC or BSC equipment with high energy conversion efficiency and stable crystal oscillator for synchronization.
示例3Example 3
所述目标信号包括第三信号和第四信号,所述第三信号包括射频信号、同步信号,所述第四信号包括射频信号和所述广播信息,所述第三信号的发送时间早于所述第四信号。可选的,在所述第三信号包括触发广播接收信号的情况下,所述触发广播接收信号用于触发所述第二设备接收所述第四信号。The target signal includes a third signal and a fourth signal, the third signal includes a radio frequency signal and a synchronization signal, the fourth signal includes a radio frequency signal and the broadcast information, and the sending time of the third signal is earlier than the Describe the fourth signal. Optionally, in the case where the third signal includes a trigger broadcast reception signal, the trigger broadcast reception signal is used to trigger the second device to receive the fourth signal.
其中,如图4c所示,该示例3与示例2类似,不同的地方在于在第四信号(对应示例2中的第二信号)前面增加了射频信号,以更好的支持第二设备进行储能及后续信息解调与反向散射调制。换言之,示例3中的目标信号设计方式适合于无源或能量转化效率较低,但同步晶振稳定的BSC设备。As shown in Figure 4c, Example 3 is similar to Example 2, except that a radio frequency signal is added in front of the fourth signal (corresponding to the second signal in Example 2) to better support the second device for storage. Capable of subsequent information demodulation and backscatter modulation. In other words, the target signal design method in Example 3 is suitable for BSC equipment that is passive or has low energy conversion efficiency, but the synchronous crystal oscillator is stable.
示例4Example 4
所述目标信号包括第五信号和第六信号,所述第五信号包括射频信号、同步信号,所述第六信号包括同步信号和所述广播信息,所述第五信号的发送时间早于所述第六信号。可选的,在所述第五信号包括触发广播接收信号的情况下,所述触发广播接收信号用于触发所述第二设备接收所述第六信号。The target signal includes a fifth signal and a sixth signal. The fifth signal includes a radio frequency signal and a synchronization signal. The sixth signal includes a synchronization signal and the broadcast information. The sending time of the fifth signal is earlier than the Describe the sixth signal. Optionally, in the case where the fifth signal includes a trigger broadcast reception signal, the trigger broadcast reception signal is used to trigger the second device to receive the sixth signal.
其中,如图4d所示,该示例4与示例2类似,不同之处在于在广播信息所在的第六信号(对应示例2中的第二信号)中的增加了同步信号,从而支持BSC设备实现更好的同步。其中,第五信号中的同步是为了使得第二设备能够接收触发广播接收信号。As shown in Figure 4d, Example 4 is similar to Example 2, except that a synchronization signal is added to the sixth signal (corresponding to the second signal in Example 2) where the broadcast information is located, thereby supporting BSC equipment implementation Better synchronization. The synchronization in the fifth signal is to enable the second device to receive the trigger broadcast reception signal.
基于此,示例4中目标信号设计方式适合于半无源或者能量转化效率较高,但同步晶振性能较差的第二设备,因而需要定期发送同步信号用于同步。Based on this, the target signal design method in Example 4 is suitable for semi-passive or second devices with high energy conversion efficiency but poor synchronization crystal oscillator performance, so synchronization signals need to be sent regularly for synchronization.
示例5Example 5
所述目标信号包括第七信号和第八信号,所述第七信号包括射频信号,所述第八信号包括同步信号和所述广播信息,所述第七信号的发送时间早于所述第八信号。
The target signal includes a seventh signal and an eighth signal. The seventh signal includes a radio frequency signal. The eighth signal includes a synchronization signal and the broadcast information. The sending time of the seventh signal is earlier than the eighth signal. Signal.
如图4e所示,将射频信号单独承载在第七信号中,而将同步信号和广播信息联合承载在第八信号中,这种设计方式适合于储能时间较长或者能量转化效率较弱的第二设备;并且将BSC通信相关的信号与射频信号进行解耦,能够降低第一设备的处理复杂度,预留更多的时间支持射频信号(如载波/激励信号)和同步信号的生成。As shown in Figure 4e, the radio frequency signal is carried alone in the seventh signal, and the synchronization signal and broadcast information are jointly carried in the eighth signal. This design method is suitable for long energy storage time or weak energy conversion efficiency. second device; and decoupling BSC communication-related signals from radio frequency signals can reduce the processing complexity of the first device and reserve more time to support the generation of radio frequency signals (such as carrier/excitation signals) and synchronization signals.
需要注意。前述的目标信号的设计方式可以是但不限于前述示例1-示例5所示,例如,广播信息中各信息的顺序可与前述示例1-示例5中不同等。requires attention. The design method of the aforementioned target signal may be, but is not limited to, what is shown in the aforementioned Example 1 to Example 5. For example, the order of each information in the broadcast information may be different from that in the aforementioned Example 1 to Example 5.
进一步,对于前述目标信号的描述,所述第一设备可以根据获取的目标配置信息确定,该目标配置信息是与所述BSC通信能力相关的配置。此外,所述第一设备还可以根据所述目标配置信息与至少一个所述第二设备进行反向散射通信。Further, for the description of the aforementioned target signal, the first device may determine based on the acquired target configuration information, which is a configuration related to the BSC communication capability. In addition, the first device may also perform backscatter communication with at least one of the second devices according to the target configuration information.
