一种传输信号方法及装置Method and device for transmitting signals技术领域technical field

本申请实施例涉及通信技术领域，尤其涉及一种传输信号方法及装置。The embodiments of the present application relate to the field of communication technologies, and in particular, to a method and apparatus for transmitting signals.

背景技术Background technique

无源物联网(passive internet of things，passive IoT)是目前第5代移动通信技术(5th generation，5G)或者5.5G物联领域中重要的研究方向。无源物联系统中，网络设备和无源标签通信过程包括选择无源标签过程和盘存无源标签过程。Passive internet of things (passive IoT) is an important research direction in the field of 5th generation mobile communication technology (5th generation, 5G) or 5.5G IoT. In the passive IoT system, the communication process between network devices and passive tags includes the process of selecting passive tags and inventorying passive tags.

其中，在无源标签盘存过程中，无源标签接收到来自网络设备的查询(query)信令,query信令包括参数Q，该无源标签从(0，2^Q－1)的范围内选出一个随机数存入无源标签的时隙计数器中，此时选到非0值的无源标签转移到仲裁状态，并触发时隙计数器进行逐一递减计数，直至计数至0时无源标签进入响应状态，而选到0值的无源标签直接进入响应状态。进入响应状态的无源标签响应一个16位随机数或伪随机数(16-bit random or pseudo-random number，RN16)给网络设备，随后网络设备接收到RN16后，响应一个包含该RN16的确认应答(acknowledgement，ACK)给无源标签，此时，无源标签被成功确认。被确认的无源标签转移到确认状态，并向网络设备反射无源标签的相关信息，比如无源标签的产品电子代码(electronic product code，EPC)、16位循环冗余码校验(16-bit cyclic redundancy check，CRC-16)等。Among them, in the passive tag inventory process, the passive tag receives the query signaling from the network device, the query signaling includes the parameter Q, and the passive tag is selected from the range of (0, 2^Q -1). A random number is stored in the time slot counter of the passive tag. At this time, the passive tag with a non-zero value is selected and transferred to the arbitration state, and the time slot counter is triggered to count down one by one until the passive tag enters when the count reaches 0. The response state, and the passive tag selected to the value of 0 directly enters the response state. The passive tag that enters the response state responds to a 16-bit random or pseudo-random number (16-bit random or pseudo-random number, RN16) to the network device. After receiving the RN16, the network device responds with an acknowledgment containing the RN16. (acknowledgement, ACK) to the passive tag, at this time, the passive tag is successfully acknowledged. The confirmed passive tag transfers to the confirmed state, and reflects the relevant information of the passive tag to the network device, such as the product electronic code (electronic product code, EPC) of the passive tag, 16-bit cyclic redundancy check (16- bit cyclic redundancy check, CRC-16), etc.

但是，由于无源标签存入时隙计数器的值是随机选取的，在同一时隙下，会出现多个无源标签的时隙计数器计数为0，多个无源标签同时进入响应状态，并同时向网络设备响应RN16、反射无源标签的相关信息的现象。此时多个无源标签向网络设备反射的信号可能会叠加相互干扰，导致网络设备可能无法正确解扩多个无源标签反射的信号，进而降低多个无源标签接入网络的效率。However, since the value of the passive tag stored in the time slot counter is randomly selected, in the same time slot, the time slot counter count of multiple passive tags will be 0, and multiple passive tags will enter the response state at the same time, and At the same time, it responds to the RN16 and reflects the relevant information of the passive tag to the network device. At this time, the signals reflected by multiple passive tags to the network device may overlap and interfere with each other, which may cause the network device to fail to correctly despread the signals reflected by multiple passive tags, thereby reducing the efficiency of multiple passive tags accessing the network.

为了使本申请的目的、技术方案和优点更加清楚，下面将结合附图对本申请作进一步地详细描述。In order to make the objectives, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings.

In the description of this application, unless stated otherwise, "plurality" means two or more.

在本申请实施例中，“示例性的”或者“例如”等词用于表示作例子、例证或说明。本申请实施例中被描述为“示例性的”或者“例如”的任何实施例或设计方案不应被解释为比其它实施例或设计方案更优选或更具优势。确切而言，使用“示例性的”或者“例如”等词旨在以具体方式呈现相关概念。In the embodiments of the present application, words such as "exemplary" or "for example" are used to represent examples, illustrations or illustrations. Any embodiments or designs described in the embodiments of the present application as "exemplary" or "such as" should not be construed as preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "such as" is intended to present the related concepts in a specific manner.

在介绍本申请实施例之前，对本申请实施例涉及的一些名词进行解释：Before introducing the embodiments of the present application, some terms involved in the embodiments of the present application are explained:

无源物联网是指包括无源(battery free)节点的传输网络。其中，无源节点自身不配备或者不主要依赖电池等电源设备，而是从环境中获取能量，支撑无源节点对数据进行感知、传输和分布式计算。一般的，无源节点可以包括无源标签(passive tag)，无源标签的收发机可以由射频场进行激励。在本申请实施例中为表述简洁起见，可以将无源标签替代性地描述为标签。标签可以和网络设备共同构成射频识别(radio-frequency identification，RFID)系统，在RFID系统中可以应用非接触式的自动识别射频技术。Passive IoT refers to a transmission network including battery free nodes. Among them, passive nodes are not equipped with or mainly rely on power equipment such as batteries, but obtain energy from the environment to support passive nodes to sense, transmit and distribute data. In general, passive nodes may include passive tags whose transceivers may be excited by a radio frequency field. In the embodiments of the present application, for the sake of brevity, passive tags may be alternatively described as tags. The tag can form a radio frequency identification (radio-frequency identification, RFID) system together with the network equipment, and the non-contact automatic identification radio frequency technology can be applied in the RFID system.

在RFID系统的工作过程中，网络设备控制RFID系统中的射频模块将无线电载波信号通过天线向外发射，当标签进入发射天线的工作区域时，标签被激活后可以将携带有标签相关信息的信号反射给网络设备，网络设备可以通过天线接收标签反射的信号后，对接收到的信号进行解扩或者解码从而获得标签的相关信息。例如，标签的协议控制位(protocol control，PC)，产品电子代码(electronic product code，EPC)和16位循环冗余码校验(16-bit cyclic redundancy check，CRC-16)，由此形成一个完整的通信链路。During the working process of the RFID system, the network device controls the radio frequency module in the RFID system to transmit the radio carrier signal through the antenna. When the tag enters the working area of the transmitting antenna, the tag can transmit the signal carrying the relevant information of the tag after being activated. It is reflected to the network device. After receiving the signal reflected by the tag through the antenna, the network device can despread or decode the received signal to obtain the relevant information of the tag. For example, the tag's protocol control bit (protocol control, PC), product electronic code (electronic product code, EPC) and 16-bit cyclic redundancy check (16-bit cyclic redundancy check, CRC-16), thus forming a complete communication link.

在RFID空口协议国际标准化组织(international organization for standardization，ISO)18000-6C中，定义标签采用动态时隙问候(ALOHA)技术向网络设备进行反射信号。图1为一种标签的通信过程示意图，如图1所示，标签可以接收来自网络设备的选择(select)信令和查询(query)信令，也可以接收响应RN16后网络设备回复的确认应答(acknowledgement，ACK)，或者接收发送携带有标签相关信息的信号后网络设备回复的否认应答(negative acknowledgement，NACK)。其中，标签收到ACK表示网络设备成功接收到标签响应的RN16，标签收到NACK表示网络设备没有成功接收到标签响应的RN16，此时标签需要再次重复发送未成功反射的信号。在图1中，网络设备向标签发送包含高电平的连续波(continuous wave，CW)，标签可以从CW中获取能量用于与网络设备之间进行通信。例如，图1中标签在T₁时间内接收CW并从中获取能量，用于向网络设备响应一个RN16或者用于向网络设备反射带有标签相关信息的信号。类似的，标签可以在T₂、T₃、T₄时间内接收CW并从中获取能量用于信令的感知或者响应。In the RFID air interface protocol International Organization for Standardization (International Organization for Standardization, ISO) 18000-6C, it is defined that the tag uses the dynamic slot hello (ALOHA) technology to reflect the signal to the network device. Figure 1 is a schematic diagram of the communication process of a tag. As shown in Figure 1, the tag can receive select signaling and query signaling from network devices, and can also receive confirmation responses from network devices after responding to RN16 (acknowledgement, ACK), or a negative acknowledgement (negative acknowledgement, NACK) replied by the network device after receiving and sending the signal carrying the tag-related information. Among them, if the tag receives ACK, it means that the network device successfully receives the RN16 of the tag response, and if the tag receives NACK, it means that the network device has not successfully received the RN16 of the tag response. At this time, the tag needs to repeat the unsuccessfully reflected signal again. In FIG. 1 , the network device sends a continuous wave (continuous wave, CW) containing a high level to the tag, and the tag can obtain energy from the CW for communicating with the network device. For example, the tag in FIG.₁ receives the CW within the time T1 and obtains energy from it, which is used to respond to an RN16 to the network device or to reflect a signal with tag-related information to the network device. Similarly, the tag can receive the CW within T₂ , T₃ , and T₄ and obtain energy from it for signaling sensing or response.

ISO 18000-6C规定在标签反射链路中，采用线性编码调制方式对待反射的信号进行调制，例如采用双相间空号编码(bi-phase space coding，FM0)/米勒(miller)线路码+二进制相移键控(binary phase shift keying，BPSK)/幅度键控(amplitude shift keying，ASK)的信息调制方式。但是，采用这种线性编码调制方式的局限性在于标签反射链 路的通信抗干扰的能力较弱，进而导致标签反射信号链路的覆盖距离严重受限。ISO 18000-6C stipulates that in the tag reflection link, the signal to be reflected is modulated by linear coding modulation, for example, bi-phase space coding (FM0)/miller line code + binary Phase shift keying (binary phase shift keying, BPSK)/amplitude shift keying (amplitude shift keying, ASK) information modulation method. However, the limitation of using this linear coding modulation method is that the communication anti-interference ability of the label reflection link is weak, which leads to a serious limitation of the coverage distance of the label reflection signal link.

一种可能的设计中，在标签反射链路中可以采用重复或者扩频+重复的方式来向网络设备反射信号。例如，标签可以向网络设备多次反射相同的信号，或者，标签在反射的相同的信号的基础上将反射信号乘以扩频序列。其中，扩频序列可以由标签自身预置或者预存。标签采用上述方式向网络设备反射信号，网络设备可以对接收到的多个信号进行合并解码，能够有效提升接收信噪比进而提高标签反射链路的覆盖性能。In a possible design, repetition or spread spectrum + repetition may be used in the label reflection link to reflect the signal to the network device. For example, the tag may reflect the same signal to the network device multiple times, or the tag may multiply the reflected signal by a spreading sequence based on the same signal that is reflected. Wherein, the spreading sequence can be preset or pre-stored by the tag itself. The tag reflects the signal to the network device in the above manner, and the network device can combine and decode multiple received signals, which can effectively improve the received signal-to-noise ratio and thus the coverage performance of the tag reflection link.

在标签反射链路中采用自身预置或者预存的扩频序列对反射信号进行处理，并与网络设备进行通信的过程可以如图2所示，图2为一种RFID系统的通信过程示意图。图2中标签1在时隙1向网络设备响应一个RN16，网络设备回应包含该RN16的ACK给标签1，标签1被成功确认，随后标签1向网络设备反射标签相关信息，例如标签1的EPC。类似的，标签2、标签3执行重复查询(queryrep)信令后与网络设备的通信过程与上述标签1的通信过程类似，不予赘述。当标签4在时隙3计数器值为0，标签4进入响应状态并向网络设备响应一个RN16，网络设备回应包含该RN16的NACK给标签4，标签4未被确认，继续重复执行queryrep信令，直至标签4被确认后，再向网络设备反射标签4的相关信息。In the tag reflection link, the self-preset or pre-stored spread spectrum sequence is used to process the reflected signal, and the process of communicating with the network device can be shown in Figure 2, which is a schematic diagram of the communication process of an RFID system. In Figure 2,tag 1 responds to the network device with an RN16 intime slot 1, and the network device responds with an ACK containing the RN16 to tag 1.Tag 1 is successfully acknowledged, and then tag 1 reflects tag-related information to the network device, such as the EPC oftag 1. . Similarly, the communication process of thetag 2 and the tag 3 with the network device after performing the queryrep signaling is similar to the communication process of thetag 1 described above, and will not be repeated. When the counter value of tag 4 in time slot 3 is 0, the tag 4 enters the response state and responds to the network device with an RN16, the network device responds with a NACK containing the RN16 to the tag 4, the tag 4 is not acknowledged, and continues to repeat the queryrep signaling, Until the tag 4 is confirmed, the relevant information of the tag 4 is reflected to the network device.

但是，如果在同一时隙下，多个同时向网络设备响应RN16的标签内预置的扩频序列是相同的，则在该时隙下多个标签反射的信号会相互叠加干扰，网络设备接收这多个标签反射的信号无法正确解扩，进而降低标签接入网络的效率。However, if in the same time slot, the preset spreading sequences in multiple tags that respond to the RN16 simultaneously to the network device are the same, the signals reflected by the multiple tags in this time slot will overlap and interfere with each other, and the network device receives The signals reflected by the multiple tags cannot be despread correctly, thereby reducing the efficiency of the tags accessing the network.

For example,tag 1 uses sequence 4 in the first set as the first sequence, maps the information bits or information blocks to be sent bytag 1 to the network device on the time domain or frequency domain, and then multiplies by sequence 4 to obtain the spread The signal transmitted on the tag reflection link after frequency processing.

S503、标签向网络设备发送处理后的信息。S503, the tag sends the processed information to the network device.

其中，网络设备可以为图3a或者图3b所示通信架构中的宏基站或者微型基站。The network device may be a macro base station or a micro base station in the communication architecture shown in Fig. 3a or Fig. 3b.

具体的，标签可以采用扩频+重复的方式向网络设备反射信息。标签向网络设备重复发送处理后的信号，以使得网络设备可以将接收到的信号进行合并解扩，进而能够有效降低传输的误码率。Specifically, the tag can reflect information to the network device in a spread spectrum + repetition manner. The tag repeatedly sends the processed signal to the network device, so that the network device can combine and despread the received signal, thereby effectively reducing the bit error rate of transmission.

例如，在标签反射链路中，预先设置固定的倍数因子为n₀，标签将相同信息比特或者信息块重复发送n₀次。对于单个标签而言，网络设备n₀次接收到标签发送的相同信息时，可以对n₀个重复的信息比特或者信息块进行合并接收。如果在一个时隙内，当多个标签同时进入响应状态，每个标签在重复发送送n₀次相同信息的基础上，将待反射的信息比特或者信息块乘以该标签对应的第一序列。For example, in the tag reflection link, a fixed multiple factor is preset as n₀ , and the tag sends the same information bit or information block repeatedly n₀ times. For a single tag, when the network device receives the same information sent by the tag n₀ times, it can combine and receive n₀ repeated information bits or information blocks. If in a time slot, when multiple tags enter the response state at the same time, each tag multiplies the information bits or information blocks to be reflected by the first sequence corresponding to the tag on the basis of repeatedly sending the same information n₀ times. .

S504、网络设备接收标签处理后的信息并进行解扩。S504, the network device receives the information processed by the label and despreads it.

其中，网络设备接收处理后的信号并进行合并解扩，获得标签的反射信号。Wherein, the network device receives the processed signal and performs combining and despreading to obtain the reflected signal of the tag.

具体的，网络设备可以根据第一序列对接收到的标签处理后的信号进行解扩。可选的，网络设备可以对第一集合中的序列轮询，并进行相关性检测，直至查找到第一序列能够成功对网络设备接收到的信号进行解扩。Specifically, the network device may despread the received label-processed signal according to the first sequence. Optionally, the network device may poll the sequences in the first set and perform correlation detection until the first sequence is found and can successfully despread the signal received by the network device.

例如，第一集合中包括8个序列：{序列0、序列1、序列2、序列3、序列4、序列5、序列6、序列7}，其中，标签1选择的第一序列为序列4，标签1根据序列4对反射信号进行处理后发送给网络设备，网络设备接收到标签1反射的信号后，对第一集合中的序列进行轮询，依次使用序列0、序列1、序列2、序列3都不能对接收到的信号成功解扩，使用序列4可以对接收到的信号成功解扩并且获得标签1的反射信号，在成功解扩后，网络设备停止对第一集合的轮询。For example, the first set includes 8 sequences: {Sequence 0,Sequence 1,Sequence 2, Sequence 3, Sequence 4, Sequence 5, Sequence 6, Sequence 7}, wherein the first sequence selected byTag 1 is Sequence 4,Tag 1 processes the reflected signal according to sequence 4 and sends it to the network device. After receiving the signal reflected bytag 1, the network device polls the sequences in the first set, and uses sequence 0,sequence 1,sequence 2, sequence 3 cannot successfully despread the received signal. Using sequence 4, the received signal can be successfully despread and the reflected signal oflabel 1 can be obtained. After successful despreading, the network device stops polling for the first set.

可选的，网络设备可以同步标签选择的第一序列，在接收到标签发送的信号后，网络设备直接利用标签同步的第一序列进行解扩。例如，第一集合中包括8个序列：{序列0、序列1、序列2、序列3、序列4、序列5、序列6、序列7}，其中，标签1选择的第一序列为序列4，标签1根据序列4对反射信号进行处理后发送给网络设备，并将序列4同步给网络设备，网络设备根据序列4对接收到的信号进行解扩，获得标签1的反射信号。Optionally, the network device may synchronize the first sequence selected by the label, and after receiving the signal sent by the label, the network device directly uses the first sequence synchronized by the label to perform despreading. For example, the first set includes 8 sequences: {Sequence 0,Sequence 1,Sequence 2, Sequence 3, Sequence 4, Sequence 5, Sequence 6, Sequence 7}, wherein the first sequence selected byTag 1 is Sequence 4,Tag 1 processes the reflected signal according to sequence 4 and sends it to the network device, and synchronizes sequence 4 to the network device. The network device despreads the received signal according to sequence 4 to obtain the reflected signal oftag 1.

进一步的，网络设备获得标签的反射信号后可以对标签进行响应或者接入。例如，网络设备成功接收到标签1响应的RN16后，可以向标签1回应一个包含同样RN16的ACK来用于确认标签1。又例如，网络设备通过信号解扩获得标签1的标签相关信息后将标签接入以太网。Further, after obtaining the reflected signal of the tag, the network device can respond to or access the tag. For example, after successfully receiving the RN16 responded by thetag 1, the network device may respond to thetag 1 with an ACK containing the same RN16 to confirm thetag 1. For another example, the network device obtains the tag-related information of thetag 1 through signal despreading and then connects the tag to the Ethernet.

图5所示方法以一个标签与网络设备之间进行为例进行说明，可理解的是，对于其他标签，可以参照图5所示方法与网络设备进行通信，例如，存在标签1、标签2、标签3、标签4在同一个时隙内进入响应状态时，标签1、标签2、标签3、标签4可以分别由标签各自的第一信息确定第一集合中第一序列的索引，根据与标签对应的第一序列对不同标签的反射信息比特进行扩频处理，可以使得标签1与标签2、标签3、标签4向网络设备发送的信号互不干扰。The method shown in FIG. 5 is described by taking a tag and a network device as an example. It can be understood that for other tags, you can refer to the method shown in FIG. 5 to communicate with the network device. For example, there aretag 1,tag 2, When tag 3 and tag 4 enter the response state in the same time slot,tag 1,tag 2, tag 3, and tag 4 can determine the index of the first sequence in the first set based on the respective first information of the tags. The corresponding first sequence performs spectrum spread processing on the reflected information bits of different tags, so that the signals sent by thetag 1, thetag 2, the tag 3, and the tag 4 to the network device do not interfere with each other.

基于图5所示方法，每个标签可以根据第一信息确定第一集合中第一序列的索引，根据索引确定对应的第一序列。由于不同标签的第一信息互不相同，因而能够降低标 签选择相同第一序列的概率，多个标签向网络设备响应的扩频信号之间互不干扰，最终能够有效提升标签接入的效率。Based on the method shown in FIG. 5 , each tag can determine the index of the first sequence in the first set according to the first information, and determine the corresponding first sequence according to the index. Since the first information of different tags is different from each other, the probability of tags selecting the same first sequence can be reduced, and the spread spectrum signals responded by multiple tags to the network device do not interfere with each other, which can ultimately effectively improve the efficiency of tag access.

下面对图5所示方法中，涉及到标签选择第一序列的方式一，方式二，方式三进行描述：In the method shown in FIG. 5 , themethod 1,method 2, and method 3 related to the label selection of the first sequence are described below:

方式一：标签根据第一信息对第一数值进行第一运算，根据运算结果确定第一集合中第一序列的索引。Manner 1: The tag performs a first operation on the first value according to the first information, and determines the index of the first sequence in the first set according to the operation result.

其中，第一信息包括标签的标识信息、标签生成的伪随机数信息中的一种或多种，例如，第一信息可以包括标签的TID、标签生成的RN16以及标签生成的另一组RNx中的一项或多项。第一数值可以由网络设备发送的指示信息进行指示，第一数值可以为第一集合中的序列数量。不同的标签的第一信息互不相同，因而可以大概率保证多个标签在同一时隙下响应网络设备时选择的第一序列不同。The first information includes one or more of tag identification information and pseudo random number information generated by the tag. For example, the first information may include the TID of the tag, the RN16 generated by the tag, and another set of RNx generated by the tag. one or more of the. The first value may be indicated by indication information sent by the network device, and the first value may be the number of sequences in the first set. The first information of different tags is different from each other, so it can be guaranteed with a high probability that the first sequences selected when multiple tags respond to the network device in the same time slot are different.

其中，标签根据第一信息对第一数值进行第一运算可以包括标签根据第一信息对第一数值进行取模运算。The tag performing the first operation on the first value according to the first information may include the tag performing a modulo operation on the first value according to the first information.

示例性的，标签可以根据第一信息中标签标识信息对第一数值进行取模运算，和/或第一标签中标签生成的伪随机数信息对第一数值进行取模运算，根据取模运算的结果确定第一集合中第一序列的索引。Exemplarily, the tag may perform a modulo operation on the first value according to the tag identification information in the first information, and/or perform a modulo operation on the first value based on the pseudo-random number information generated by the tag in the first tag, according to the modulo operation. The result of determines the index of the first sequence in the first set.

Modulo operation, the process of selecting the first sequence according to the result of the modulo operation will be described.

以第一信息仅包括标签1的TID为例，假设标签1通过网络设备发送的指示信息获得的第一数值为N，即第一集合中包括N个标签1的可选序列。当标签1接收query信令后开启盘存流程，标签1可以根据TID和第一数值N通过以下公式(1)得到索引SS_Seq_index_TID，将第一集合中与索引SS_Seq_index_TID对应的序列作为标签1的第一序列。Taking the first information only including the TID oftag 1 as an example, it is assumed that the first value obtained bytag 1 through the indication information sent by the network device is N, that is, the first set includes N optional sequences oftag 1 . Whentag 1 receives the query signaling and starts the inventory process, tag 1 can obtain the index SS_Seq index _TID according to the TID and the first value N through the following formula (1), and use the sequence corresponding to the_index SS_Seq_index _TID in the first set as thetag 1 the first sequence.

Whentag 1 receives the query signaling and starts the inventory process, tag 1 can obtain the index SS_Seq index _RN16 according to the RN16 and the first value N through the following formula (2), and use the sequence corresponding to the_index SS_Seq_index _RN16 in the first set as thetag 1 the first sequence.

SS_Seq_index_RN16＝RN16 mod N        公式(2)SS_Seq_index _RN16=RN16 mod N Formula (2)

例如，标签1生成的待响应给网络设备的RN16为1100 1011 0111 1010，网络设备发送的指示信息指示第一数值为8，二进制表示为1000，即第一集合中包括8个标签1的可选序列，根据上述公式(2)计算得到索引SS_Seq_index_RN16为2，将第一集合中索引2对应的序列2作为标签1的第一序列。For example, the RN16 generated bytag 1 to be responded to to the network device is 1100 1011 0111 1010, the indication information sent by the network device indicates that the first value is 8, and the binary representation is 1000, that is, the first set includes 8optional tags 1 sequence, the index SS_Seq_index _RN16 is calculated according to the above formula (2) to be 2, and thesequence 2 corresponding to theindex 2 in the first set is used as the first sequence of thelabel 1.

以第一信息仅包括标签1升成的另一组RNx为例，假设标签1通过指示信息获得第一数值为N，即第一集合中包括N个标签1的可选序列。当标签1接收query信令后开启盘存流程，标签1可以根据RNx和第一数值N通过以下公式(3)得到索引SS_Seq_index_RNx，将第一集合中与索引SS_Seq_index_RNx对应的序列作为标签1的第一序列。Taking the first information only including another group of RNx promoted bytag 1 as an example, it is assumed thattag 1 obtains the first value of N through the indication information, that is, the first set includes an optional sequence of N tags 1 . Whentag 1 receives the query signaling and starts the inventory process, tag 1 can obtain the index SS_Seq index _RNx according to the RNx and the first value N through the following formula (3), and use the sequence corresponding to the_index SS_Seq_index _RNx in the first set as thetag 1 the first sequence.

For the process of indexing, reference may be made to the above process, which will not be repeated.

上述方法适用于一个标签根据第一信息对第一数值进行第一运算，根据运算结果确定第一集合中第一序列的索引，也适用于在同一时隙下多个标签响应网络设备时，根据第一信息对第一数值进行第一运算，根据运算结果确定第一集合中第一序列的索引。例如，标签1、标签2、标签3、标签4在同一时隙下响应网络设备，标签2、标签3、标签4选择第一序列的过程可以参照上述标签1，标签1、标签2、标签3、标签4选择相同的第一序列的概率较低。The above method is applicable to a tag performing the first operation on the first value according to the first information, and determining the index of the first sequence in the first set according to the operation result. The first information performs a first operation on the first value, and determines the index of the first sequence in the first set according to the operation result.

The number of the multiple subsets obtained by dividing the first set is a third numerical value, and the third numerical value may be indicated by the grouping indication information sent by the network device. The multiple subsets may be numbered sequentially, for example, subset 0,subset 1, andsubset 2. The tag may perform a first operation on the first information and the third value, obtain a subset index according to the operation result, and use the subset corresponding to the subset index included in the multiple subsets divided by the first set as the second set.

下面以标签为标签1，第一信息包括标签1的TID、标签1生成的RN16、标签1生成的另一组RNx中的任一项为例，对标签1根据第一信息对第三数值进行取模运算，根据取模运算的结果选择第二集合的过程进行说明。The following takes the label aslabel 1, and the first information includes the TID oflabel 1, the RN16 generated bylabel 1, and any one of the other group of RNx generated bylabel 1 as an example. Modulo operation, the process of selecting the second set according to the result of the modulo operation will be described.

以第一信息仅包括标签1的TID为例，假设标签1通过分组指示信息获得的第三数值为M，即第一集合中包括M个已划分好的子集，并依次编号为子集0，子集1，……子集M-1。当标签1接收query信令后开启盘存流程，标签1可以根据TID和第三数值M通过以下公式(6)得到一个子集索引SS_Aggre_index_TID，将由第一集合划分的多个子集中子集索引为SS_Aggre_index_TID的子集作为第二集合。Taking the first information only including the TID oftag 1 as an example, it is assumed that the third value obtained bytag 1 through the grouping indication information is M, that is, the first set includes M divided subsets, which are sequentially numbered as subset 0. ,subset 1, ... subset M-1. Whentag 1 receives the query signaling and starts the inventory process, tag 1 can obtain a subset_index SS_Aggre index_TID according to the TID and the third value M through the following formula (6), and the subset index in the multiple subsets divided by the first set is: A subset of SS_Aggre_{index_TID} as the second set.

SS_Aggre_index_TID＝TID mod M         公式(6)SS_Aggre_index _TID=TID mod M Formula (6)

例如，标签1的TID为0010 0101 0111 0101 1111 1010 0101 1011，网络设备发送的分组指示信息指示第三数值为4，二进制表示为100，即第一集合中可以划分为4个子集，可以依次编号为子集0，子集1，子集2，子集3，根据上述公式(6)计算得到子集索引SS_Aggre_index_TID为3，将由第一集合划分的四个子集中的子集3作为第二集合。For example, the TID oftag 1 is 0010 0101 0111 0101 1111 1010 0101 1011, the grouping indication information sent by the network device indicates that the third value is 4, and the binary representation is 100, that is, the first set can be divided into 4 subsets, which can be numbered sequentially For subset 0,subset 1,subset 2, and subset 3, the subset index SS_Aggre_index _TID calculated according to the above formula (6) is 3, and the subset 3 of the four subsets divided by the first set is used as the second gather.

可选的，第一信息可以包括标签1生成的RN16或者第一信息可以包括标签1生成的另一组RNx，根据第一信息中的任意一项选择第二集合过程可以参照上述根据标签1的TID选择第二集合的过程，不予赘述。Optionally, the first information may include RN16 generated bytag 1 or the first information may include another group of RNx generated bytag 1, and the process of selecting the second set according to any one of the first information may refer to the above-mentioned method based ontag 1. The process of selecting the second set by the TID will not be repeated.

具体的，当第一信息包括标签的TID、RN16、RNx中的多项内容时，标签可以根据第一信息中每项内容遍历的结果，对第二数值进行取模运算，根据取模运算的结果获得一个子集索引集合，例如，该子集索引集合可以为：{SS_Aggre_index_TID，SS_Aggre_index_RN16，SS_Aggre_index_RNx}，标签可以从子集索引集合中随机选取一个作为第二集合的子集索引，将由第一集合划分的子集中，与该子集索引对应的子集作为第二集合。Specifically, when the first information includes multiple contents in the TID, RN16, and RNx of the tag, the tag can perform a modulo operation on the second value according to the result of traversing each item in the first information, and according to the result of the modulo operation As a result, a subset index set is obtained. For example, the subset index set can be: {SS_Aggre_index _TID, SS_Aggre_index _RN16, SS_Aggre_index _RNx}, and the label can randomly select a subset from the subset index set as a subset of the second set The index, in the subset divided by the first set, takes the subset corresponding to the index of the subset as the second set.

进一步的，标签可以根据第一信息对第一数值进行第一运算，根据运算结果确定第二集合中第一序列的索引。具体的，可以参照上述方式一中标签根据运算结果确定第一集合中第一序列的索引的实现过程，不予赘述。Further, the tag may perform a first operation on the first value according to the first information, and determine the index of the first sequence in the second set according to the operation result. Specifically, reference may be made to the implementation process of the label determining the index of the first sequence in the first set according to the operation result in the first manner, which will not be repeated.

标签根据上述方式二确定第二集合中第一序列的索引，根据第二集合中第一序列的索引处理反射信息比特，并将处理后的信号发送给网络设备，网络设备接收到标签处理后的信号后，对第二集合中的序列轮询，进行相关性检测，并对接收到的信号进行解扩。相比于对第一集合中的所有序列轮询进行相关性检测，仅对第一集合的子集中的个序列轮询检测，网络设备在解扩时轮询的序列范围缩小，能够有效降低解扩的复杂度。The tag determines the index of the first sequence in the second set according to theabove method 2, processes the reflected information bits according to the index of the first sequence in the second set, and sends the processed signal to the network device, and the network device receives the processed signal from the tag. After the signal, the sequences in the second set are polled, correlation detection is performed, and the received signal is despread. Compared with performing correlation detection on all sequence polling in the first set, only performing polling detection on sequences in a subset of the first set reduces the range of sequences polled by the network device during despreading, which can effectively reduce the problem of despreading. expansion complexity.

方式三：标签根据第一信息对第二数值进行第一运算，根据运算结果确定第三集合中第二序列的索引，标签根据第二序列的索引以及第二信息确定第一序列的索引。Mode 3: The tag performs a first operation on the second value according to the first information, determines the index of the second sequence in the third set according to the operation result, and determines the index of the first sequence according to the index of the second sequence and the second information.

其中，第二信息包括标签的标识信息、标签生成的伪随机数信息中的一种或多种，例如，第二信息包括标签的TID、标签生成的RN16、标签生成的另一组RNx中的一项或多项。第二数值可以由网络设备发送的指示信息进行指示，第二数值可以第三集合中的序列的数量。Wherein, the second information includes one or more of tag identification information and pseudo random number information generated by the tag, for example, the second information includes the TID of the tag, the RN16 generated by the tag, and the RN16 generated by the tag in another group of RNx generated by the tag. one or more. The second value may be indicated by indication information sent by the network device, and the second value may be the number of sequences in the third set.

其中，第三集合包括多个相互正交的序列，该多个序列可以依次编号，例如序列0，序列1，序列2，序列3。第三集合中的序列长度小于第一集合中序列的长度，且第三集合中的序列为第一集合中序列的基序列，即第一集合中的序列可以由第三集合中的序列生成。The third set includes multiple mutually orthogonal sequences, and the multiple sequences may be numbered sequentially, for example, sequence 0,sequence 1,sequence 2, and sequence 3. The length of the sequences in the third set is smaller than the length of the sequences in the first set, and the sequences in the third set are the base sequences of the sequences in the first set, that is, the sequences in the first set can be generated from the sequences in the third set.

Among them, the root code C_0,0 =(1), C_0,0 can generate two spreading sequences of length 2: when C_0,0 is 1 in the next step, C_1,0 =(1,1) is obtained, When C_0,0 is 0 in the next step, C_1,1 =(1,-1) is obtained. C_1,0 and C_1,1 can generate four spread spectrum sequences of length 4: C_1,0 is 1 to get C_2,0 =(1,1,1,1),C_1,0 When the next step is 0, you get C_2,1 =(1,1,-1,-1), and when C_1,1 is 1 in the next step, you get C_2,2 =(1,-1,1,-1), When C_1,1 is 1 in the next step, C_2,3 =(1,-1,-1,1) is obtained. Wherein, the third set may include {C_2,0 , C_2,1 , C_2,2 , C_2,3 }, and the sequences in the third set may generate eight spreading sequences of length 8, the eight Spreading sequences of length 8 can form the first set {C_3,0 , C_3,1 , C_3,2 , C_3,3 , C_3,4 , C_3,5 , C_3,6 , C_{3 ,7} }.

具体的，标签根据第一信息对第二数值进行第一运算，根据运算结果确定第三集合中第二序列的索引的过程可以参照上述方式一或者方式二中确定第一序列的索引的过程，不予赘述。Specifically, the tag performs the first operation on the second value according to the first information, and the process of determining the index of the second sequence in the third set according to the operation result may refer to the process of determining the index of the first sequence in the above-mentionedmethod 1 ormethod 2, I won't go into details.

进一步的，标签可以根据第二序列的索引以及第二信息确定第一序列的索引。Further, the tag may determine the index of the first sequence according to the index of the second sequence and the second information.

具体的，标签可以根据第二信息的一位或者多位确定第二序列下一步是0还是1，进而确定第一序列的索引。Specifically, the tag can determine whether the next step of the second sequence is 0 or 1 according to one or more bits of the second information, and then determine the index of the first sequence.

以第二信息仅包括标签的TID为例展开说明。例如，标签可以根据标签TID的首位确定第二序列下一步是0还是1，标签1的TID首位为0，则第二序列下一步为0。标签2的TID首位为1，则第二序列下一步为1。The second information only includes the TID of the tag as an example to expand the description. For example, the tag can determine whether the next step of the second sequence is 0 or 1 according to the first position of the tag TID, and the first position of the TID oftag 1 is 0, then the next step of the second sequence is 0. The first TID oftag 2 is 1, and the next step of the second sequence is 1.

又例如，标签可以根据标签TID的最后两位确定下一步是0还是1，其中，标签TID的最后两位为00或11，则确定第二序列下一步为1，标签TID的最后两位为10或01，则确定第二序列下一步为0。第二信息包括标签生成的RN16或者标签生成的另一组RNx时，标签确定第二序列下一步序列生成情况的过程可以参照上述过程，不予赘述。For another example, the tag can determine whether the next step is 0 or 1 according to the last two digits of the tag TID, where the last two digits of the tag TID are 00 or 11, then it is determined that the next step of the second sequence is 1, and the last two digits of the tag TID are 10 or 01, then it is determined that the next step of the second sequence is 0. When the second information includes the RN16 generated by the label or another group of RNx generated by the label, the process for the label to determine the next sequence generation of the second sequence may refer to the above process, which will not be repeated.

可选的，标签可以根据第二信息其中多项的一位或者多位共同确定第二序列的下一步是0还是1。Optionally, the tag may jointly determine whether the next step of the second sequence is 0 or 1 according to one or more bits of the multiple items of the second information.

以第二信息包括TID和RN16为例展开说明，例如，标签1的TID首位为1，标签1的RN16末位为0，则确定标签1的第二序列下一步为1；标签2的TID首位为0，标签2的RN16末位为1，则确定标签2的第二序列下一步为0。Take the second information including TID and RN16 as an example to expand the description. For example, the first bit of TID oftag 1 is 1, and the last bit of RN16 oftag 1 is 0, then it is determined that the next step of the second sequence oftag 1 is 1; the first bit of TID oftag 2 is 1; is 0, the last bit of RN16 oftag 2 is 1, then it is determined that the second sequence oftag 2 is 0 in the next step.

示例性的，标签可以根据第二信息可以确定第二序列下一步生成的第一序列的索引。Exemplarily, the tag may determine, according to the second information, an index of the first sequence that is next generated by the second sequence.

下面以标签为标签1，对标签1根据第二序列的索引和第二信息通过确定第一序 列的索引的过程进行说明。Taking the label aslabel 1, the process of determining the index of the first sequence bylabel 1 according to the index of the second sequence and the second information will be described below.

例如，标签1通过网络设备发送的信令确定标签1选择的第一序列的长度为8。标签1的TID为0010 0101 0111 0101 1111 1010 0101 1011，网络设备发送的指示信息指示第二数值为4，二进制表示为100，即第三集合中包括4个标签1的可选序列。根据上述公式(1)计算得到第二序列的索引SS_Seq_index_TID为3，第三集合中包括的序列2为标签1的第二序列，序列3可以为图6中的C_2,3＝(1,-1,-1,1)。根据标签1的TID首位为0，确定第二序列下一步为0，进行后获得长度为8的第一序列的索引，根据该索引可以确定第一序列为图6中的C_3,6＝(1,-1,-1,1，1,-1,-1,1)。For example,tag 1 determines that the length of the first sequence selected bytag 1 is 8 through signaling sent by the network device. The TID oftag 1 is 0010 0101 0111 0101 1111 1010 0101 1011, and the indication information sent by the network device indicates that the second value is 4, and the binary representation is 100, that is, the third set includes four optional sequences oftag 1. Calculated according to the above formula (1), the_index SS_Seq index_TID of the second sequence is 3, thesequence 2 included in the third set is the second sequence of thetag 1, and the sequence 3 can be C_2,3 =(1 ,-1,-1,1). According to the first TID of thetag 1 is 0, it is determined that the next step of the second sequence is 0, and the index of the first sequence with a length of 8 is obtained after the process. According to the index, it can be determined that the first sequence is C_3,6 =( 1,-1,-1,1,1,-1,-1,1).

标签根据上述方法三获得第一序列，能够进一步降低同一时隙下多个标签标签选取到相同第一序列的概率，有效的提升实际网络设备识别标签的效率。The label obtains the first sequence according to the third method, which can further reduce the probability of selecting the same first sequence for multiple labels in the same time slot, and effectively improve the efficiency of the actual network device to identify the label.
