- the Select type (Select) command is necessary. Since tags have multiple attributes, based on the standards and strategies set by the user, using the Select type command to change certain attributes and flags artificially selects or delimits a specific tag group. You can only perform inventory identification or access operations on them, which will help reduce conflicts and repeated identification and speed up identification.
- the inventory phase command is used to start an inventory.
- the query command is used to start a round of inventory and determine which tags participate in the round of inventory;
- the adjustment query command is used to adjust the number of tags' original receiving time slots (Slots);
- the repeat query command is used to reduce the number of tag Slots.
- the random request (Req_RN) command requires the tag to generate a random number; the read command is used to read data from a certain location in the tag's storage; the write command is used to write data to the tag's storage.
- the destroy command can leak privacy and the tag can no longer be used; the lock command is used to prevent the tag from being written to, preventing the data from being arbitrarily modified; the access command is used to make the tag open when the tag has a password ( Open) state is converted to the Secure state; security-related access commands are used to ensure tag security; file management-related access commands can be used to manage files within the tag.
- the information carried by the Tag reflection signal includes, for example: Tag identification information (such as a 16-bit random number that temporarily represents the Tag identity during the query process), electronic product code information, Tag status information, etc.).
- Tag identification information such as a 16-bit random number that temporarily represents the Tag identity during the query process
- electronic product code information such as a 16-bit random number that temporarily represents the Tag identity during the query process
- Tag status information such as a 16-bit random number that temporarily represents the Tag identity during the query process

- Backscatter communication can include the following scenarios:
- the network sends CW and signaling and receives the reflected signal of the tag.
- the terminal sends CW and signaling and receives the reflected signal of the tag.
- the network sends CW and signaling to the Tag, and the terminal receives the backscatter information sent by the Tag.
- the terminal sends CW and signaling to the Tag, and the network receives the backscatter information of the Tag.

- the first module is the main communication module for sending and receiving mobile communication data
- the second module is for low-power reception.
- Module also called low-power wake-up receiving module
- the terminal turns on the low-power receiving module to monitor LP-WUS and turns off the main Communication module.
- the network will send a wake-up signal to the terminal.
- the terminal monitors the wake-up signal through the low-power receiving module and makes a series of judgments to trigger the main communication module from off to on.
- the low-power receiving module Enter the shutdown state from the working state.
- the low-power wake-up receiving module can be turned on continuously or intermittently, and can receive low-power wake-up signals when turned on.
- a near-terminal module can be introduced into the terminal's receiving module.
- a “zero" power receiver is thus achieved.
- This nearly “zero” power receiver does not require complex RF module signal detection (such as amplification, filtering, quantization, etc.) and MODEM signal processing, and only relies on passive matched filtering and smaller power consumption signal processing.
- a near-zero power receiver can be activated to obtain the activation notification, thereby triggering a series of processes within the terminal, such as turning on radio frequency transceiver and baseband processing, etc. module.
- This kind of wake-up signal is usually some relatively simple on-off keying signal.
- the time domain pattern of the on-off keying signal is shown in Figure 3, so that the receiver can pass simple energy detection, and then Processes such as possible sequence detection and identification are informed of wake-up notifications.

- Application example 1 Use the start sequence and the end sequence to represent the start and end of monitoring of the information block included in the control command of backscattering communication.
- Split backscatter commands such as read and write commands, according to specific splitting rules.
- the read and write command carries 100 bits of information.
- the splitting rule is to split the 100 bits into 5 sub-blocks according to the length of a sub-block of 20 bits. The first sub-block among these five sub-blocks is the starting sub-block, the last sub-block is the ending sub-block, and the remaining sub-blocks are the intermediate sub-blocks.
- the starting sequence is the first preamble sequence.
- the first preamble sequence can indicate that the type of the starting sub-block is a starting sub-block;

Therefore, it is necessary to limit the size of each information block to a specific size. This specific size is agreed upon by the network configuration or protocol. In addition, the start sequence and end sequence added for the start sub-block and end sub-block are also agreed by the network configuration or protocol.

- the network configures 2 or 3 bits specifically to carry the number corresponding to each sub-block or information block. This part can be a similar process to the above starting sequence and ending sequence, as shown in Figure 10. .

- the information of the listening time window can be carried through the starting information block, the transmission of some subsequent information blocks can be completed within the listening time window, so there is no need to add similar application examples 1 and 1 to subsequent information blocks.
- this application example does not exclude the possibility of using a listening time window in combination with a sequence or number.

传统RFID中的反向散射通信设备,一般是一个标签(Tag),属于无源物联网(Internet of Things,IoT)设备(Passive-IoT);
半无源(semi-passive)的tag,这类tag的下行接收或者上行反射具备一定的放大能力;
具备主动发送能力的tag(active tag),这类tag可以不依赖对入射信号的反射向阅读器(reader)发送信息。
本实施例中,反向散射通信包括以下内容的传输:
(1)激励载波(carrier wave,CW);一种实施例中,该激励载波可以是由网络侧设备发送给标签(tag)的,还可以是由终端发送给标签的。
(2)控制命令(command),例如:选取命令、查询命令、重复查询命令、答复命令、
读取命令、写入命令、随机请求命令等;一种实施例中,该控制命令可以是由网络侧设备发送给标签(tag)的,还可以是由终端发送给标签的。

选择类型(Select)命令是必备的,由于标签有多种属性,基于用户设定的标准和策略,使用选择类型命令,改变某些属性和标志就人为选择或圈定了一个特定的标签群,可以只对它们进行盘点识别或存取操作,这样有利于减少冲突和重复识别,加快识别速度。
盘点阶段的命令用于开始一次盘点。例如,查询命令用于启动一轮盘点,并决定哪些标记参与该轮盘点;调节查询命令用于将标签原来接收时隙(Slot)的数目进行调整;重复查询命令用于减少标签Slot的数字。
接入命令(Access)中,随机请求(Req_RN)命令要求标签产生一个随机数;读取命令用于从标签的存储中的某个位置读取资料;写入命令用于写入资料到标签的存储中;销毁命令可以隐私的泄漏,标签无法再使用;锁定命令用于标签不能再进行写入的动作,防止资料被任意的串改;访问命令用于当标签拥有密码时候让标签从开启(Open)的状态转成保护(Secure)状态;安全相关接入命令用于保障标签安全;文件管理相关接入命令可以用于对标签内文件进行管理。
(3)Tag反射信号承载的信息(也称作,反向散射信息),包括,例如:Tag标识信息(如查询过程中的临时代表Tag身份的16-bit随机数)、电子产品代码信息、Tag状态信息等)。一种实施例中,该反向散射信道或信号可以是标签通过反向散射发送给终端的,还可以是标签通过反向散射发送给网络侧设备的。
二、backscatter通信应用场景
backscatter通信可以包括以下场景:
1、网络发送CW和信令并接收tag的反射信号。
2、终端发送CW和信令并接收tag的反射信号。
3、网络发送CW和信令给Tag,终端接收Tag发送的反向散射信息。
4、终端发送CW和信令给Tag,网络接收Tag的反向散射信息。
三、低功耗接收机
低功耗接收机,即低功耗唤醒接收机(low power wake up radio,LP-WUR)。LP-WUR的基本工作原理为接收端包含第一模块和第二模块,具体如图2所示,第一模块为主通信模块,用于移动通信数据的收发,第二模块为低功耗接收模块(也称低功耗唤醒接收模块),用于接收上述唤醒信号。终端在节能状态下开启低功耗接收模块来监听LP-WUS且关闭主
通信模块。当有下行数据到达时,网络会发送唤醒信号给终端,终端通过低功耗接收模块监听到唤醒信号后通过一系列的判断后触发主通信模块从关闭到开启,而此时低功耗接收模块从工作态进入关闭状态。低功耗唤醒接收模块可以连续开启,或间歇性开启,在开启时可接收低功耗唤醒信号。
四、低功耗唤醒信号
为了减少终端在待机状态下的接收活动,使得射频(Radio Frequency,RF)和基带(MODEM)模块真正的关闭,从而大大降低通信接收的功耗,可以通过在终端的接收模块中引入了一个近“零”功率的接收机从而实现。这个近“零”功率的接收机不需要复杂的RF模块的信号检测(如放大、滤波、量化等等)和MODEM的信号处理,只靠被动的匹配滤波和较小功耗的信号处理。
在基站侧,通过按需(on-demand)触发唤醒信号,就可以激活近“零”功率的接收机获知激活的通告,从而触发终端内部的一系列流程,例如,打开射频收发以及基带处理等模块。
这种唤醒信号通常来说是一些比较简单的开关键控信号(on-off keying),开关键控信号的时域样式如图3所示,那样接收机就可以通过简单的能量检测,以及之后的可能的序列检测识别等过程获知唤醒通告。此外,在终端开启低功耗唤醒接收机来接收唤醒信号的同时,主接收机模块可以维持在一个较低耗电水平下工作,从而通过接收唤醒信号来实现功耗节省。
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信息传输方法、装置、接收端及发送端进行详细地说明。
如图4所示,本申请实施例提供一种信息传输方法,包括:
步骤401,接收端接收至少一个信息块;
步骤402,所述接收端根据所述至少一个信息块,获取第一数据;
其中,所述第一数据包括以下至少一项:唤醒信号、反向散射通信的信息。
需要说明的是,该至少一个信息块可以理解为接收端只接收一个信息块或者是接收端接收至少两个信息块。
需要说明的是,该反向散射通信的信息可以包括反向散射通信的控制命令和/或反向散射通信的Tag反射信号。
具体地,控制命令可以包括如表1所示的指令。
表1控制命令及功用介绍对照表
可选地,本申请实施例中的至少一个信息块是由发送端发送的,发送端需要先将待发送的第一数据拆分为至少一个子块;然后根据所述至少一个子块,向接收端发送至少一个信息块;通常来说,每个子块需要对应到一个信息块。
也就是说,发送端需要将第一数据拆分为一个或多个子块,然后对每个子块进行组装,最后形成至少一个信息块,然后进行信息块的发送。
可选地,所述发送端基于第四信息,将待发送的第一数据拆分为至少一个子块;
其中,所述第四信息包括以下至少一项:
A11、第一数据所拆分的子块的个数信息;
A12、子块的比特长度;
需要说明的是,上述的A11以及A12可以只存在其中的一项,即基于个数或长度就可以确定一共需要拆分为多少个子块。
A13、所述第一数据的分割方式;
本申请的至少一个实施例中,该第一数据的分割方式包括以下至少一项:
A131、将所述第一数据进行比特划分,每个子块中承载所述第一数据的部分比特;
此种情况下,发送端可以按照第一数据的比特构成顺序,依次进行比特的拆分,得到多个子块,每个子块中包含部分比特;例如,第一数据总共包含100比特,分别按照20个比特为一组,总共将第一数据拆分为5个子块,每个子块承载一个20比特。
需要说明的是,此种分割方式下,由于每个子块所携带的信息不具有完整性。因此,接收端在接收的时候,会针对每个信息块中除子块外的一些附件信息(例如编码、监听时间窗、起始/中间/结束序列)进行解码。然后,在接收完所有信息块之后,再提取出每个信息块的子块部分进行联合解码,获得完整的第一数据。
A132、将所述第一数据进行子数据划分,每个子块承载所述第一数据的子数据,所述子数据为所述第一数据所承载的指示信息中的子指示信息;
此种情况下,发送端可以按照第一数据中所承载的指示信息,对指示信息进行子指示信息的拆分,例如,第一数据中承载指示A,而指示A包含子指示A1、子指示A2和子指示A3,则对第一数据进行拆分后分别得到3个子块,3个子块分别承载指示A1、子指示A2和子指示A3。
需要说明的是,此种分割方式下,由于每个子块相当于一个完整的指示信息,因此在接收端接收完一个信息块后,可以独立的解码出相应的子指示信息,而无需等到接收完所有信息块之后再进行控制信息的解码。
例如,如图5所示,发送端将一个反向散射通信的控制命令(包括前导以及控制命令载荷)分为了6个子块,分别包括排列在第一个子块(可以称为起始子块)、排列在最后的一个子块(可以称为结束子块)以及排列在第一个子块以及最后一个子块之间的子块(可以称为中间子块),按照A131的分割方式,则只需将控制命令按照从前往后对应进行比特拆分即可;按照A132的分割方式,发送端需要设置好分割规则,然后将控制命令分为多个子命令,接收端在合并时可通过与分割规则对应的合并规则进行子命令的合并。
可选地,对应于上述的分割方式,所述与子块对应的信息块满足以下一项:
A21、所述信息块承载所述第一数据的部分比特;

还需要说明的是,本申请实施例中的发送端可以为网络侧设备。例如,网络侧设备为
接入网设备,该接入网设备的类型包括但不限于:集成接入回传(Integrated Access and Backhaul,IAB)站(IAB node);中继器(repeater),例如,网络控制中继器(network controlled repeater);杆站(Pole station)等。
该接收端可以为反向散射通信中的反向散射设备,例如Tag,也可以为终端设备。
例如,在第一数据为唤醒信号的情况下,发送端为网络侧设备,接收端为终端设备。例如,在第一数据为反向散射通信的控制命令的情况下,发送端为网络侧设备,接收端为Tag;或者,发送端为终端设备,接收端为Tag。例如,在第一数据为反向散射通信的Tag反射信号的情况下,发送端为Tag,接收端为终端设备;或者,发送端为Tag,接收端为网络侧设备。
下面以第一数据为反向散射通信的控制命令为例,对本申请的具体应用进行说明如下。
应用实例一、采用起始序列,结束序列来表示一个反向散射通信的控制命令所包括的信息块的监听起始与监听结束
发送端侧:
按照特定的拆分规则将反向散射命令,例如读写命令(read command)做拆分。该读写命令携带信息比特为100比特。拆分规则是将这100比特按照20比特一个子块的长度进行拆分,则拆分成5个子块。这5个子块中的第一个子块为起始子块,最后一个子块为结束子块,则剩余的子块为中间子块。
按照预设的规则将不同类型的子块进行分装:
针对起始子块,将加入起始序列,起始序列为第一前导序列。此外,该第一前导序列能够表示该起始子块的类型为起始子块;
可选地,针对中间子块,可以加入中间序列,也可以不加中间序列(图9中是以中间子块不加中间序列为示意),中间序列为第二前导序列。此外,该第二前导序列能够表示该起始子块的类型为中间子块;
针对结束子块,将加入结束序列,结束序列为第三前导序列。此外,该第三前导序列能够表示该起始子块的类型为结束子块。
需要说明的是,起始序列、中间序列、结束序列为不同序列,子块分装后形成信息块。
接收端侧:
接收与该读写命令关联的5个信息块;然后提取这5个信息块中的子块比特,重组成一个完整的读写命令的控制信息净荷部分。
拆分后因为要避免每个信息块的长度过大导致TDD框架下无法连续传输,因此,需要限制每个信息块的大小不能超过特定大小,这个特定大小由网络配置或协议约定。此外,为起始子块和结束子块所添加的起始序列和结束序列这个也由网络配置或协议约定。
具体地,发送端与接收端实现反向散射通信的控制命令的传输的过程示意如图9所示。
应用实例二、采用索引(例如,信息块的编号)确定一个反向散射通信的控制命令所关联的信息块的起始信息块与结束信息块,起始信息块携带控制命令关联的信息块的总个
数
在发送端进行分装的时候,也可以针对不同的子块添加相应的编号信息。比如,由网络配置2个或3个比特,专门用来承载每个子块或信息块分别对应的编号,这部分可以与上面的起始序列跟结束序列是类似的过程,具体如图10所示。有一点需要强调的是,因为编号并不能确定哪一个信息块为结束信息块,这里可以通过起始信息块携带的信息块的总个数来确定。
应用实例三、采用监听时间窗来确定一个反向散射通信的控制命令所关联的信息块的起始信息块与结束信息块
从发端的角度看,在起始子块分装的时候加入监听时间窗的信息,用于指示后续(也可以理解为包括起始子块在内的)子块的时域监听范围。在本申请中,由于可以通过起始信息块携带监听时间窗的信息,后续的一些信息块的传输可以在该监听时间窗内完成传输,因此可以不用在后续信息块中增加类似应用实例一、应用实例二中给出的序列或编号信息。当然,为了传输可靠性,该应用实例并不排除结合使用监听时间窗与序列或编号的可能。
从接收端的角度看,在接收到起始信息块后,根据对起始信息块的解码可以获得监听时间窗的信息,用于后续剩余的信息块的接收。在接收完所有信息块后,可以获得对应的控制命令。
具体地,发送端与接收端实现反向散射通信的控制命令的传输的过程示意如图11所示,图11中中间子块直接生成中间信息块,而不用与其他信息进行组装。
应用实例四、采用监听时间窗、起始序列、中间序列、结束序列以及编号中任意两项来确定一个反向散射通信的控制命令所关联的信息块的起始与结束
需要说明的是,该应用实例是上述应用实例一至应用实例三的两两结合,具体应用参见上述的实例,在此不再赘述。
需要说明的是,本申请的至少一个实施例,实现了TDD场景下反向散射通信以及唤醒信号的非连续传输,解决了TDD场景下反向散射通信以及唤醒信号非连续传输的问题,提升了反向散射通信以及唤醒信号的传输可靠性。
