Description

Technical Field

[0001] This application relates to the field of communication technologies, and in particular, to an information transmission method, apparatus, related device, and storage medium. Background Art

[0002] For the on-off keying (OOK) modulation waveform, considering that the receiver is relatively simple, generally only an envelope receiver can be used for reception, and some very complex frequency-domain multiple access technologies cannot be performed. Mainly, time-division multiple access (TDMA) is used for multiple access of different users. In existing radio frequency technologies, the OOK modulation method is usually used to transmit tag data of multiple users.

[0003] In some scenarios, such as during initial access or interrogation, due to the existence of multi-user conflicts, it is necessary to allow multiple users to reuse the same time-frequency resources for transmission to reduce the probability of blocking. However, it is difficult for OOK modulation to achieve multi-user multiplexing by means of sequence superposition, and it is difficult to meet the orthogonality of sequences between users. Moreover, due to the existence of the near-far effect, the transmission performance is very poor. Summary of the Invention

[0055] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0056] To make the embodiments of the present application clearer, the following first introduces the relevant technical knowledge involved in the embodiments of the present application:

[0057] The embodiments of the present application can be mainly applied to the field of radio frequency identification (RFID) technology, in the RFID tag inventory scenario with an RFID tag (Tag) as the sending end and a reader as the receiving end. The existing inventory process of ultra-high frequency (UHF) RFID mainly involves the following instructions:

[0058] Table 1 Instructions for reader operations

[0059]

[0060]

[0061] Among them, EPC is the Electronic Product Code, ACK is the Acknowledgment, and NAK is the Negative Acknowledgment.

[0062] Currently, in the inventory mode of the UHF RFID protocol design, it is required that after the reader sends a Query instruction, the Tag responds with a Reply, that is, generates a 16-bit random number for the reader; then after the reader sends this random number sequence to the Tag via the ACK instruction, the Tag sends the relevant data to the reader.

[0063] For the circuit design at the Tag end, it is required to have sufficient received signal power, which is output to the subsequent Digital State Machine after passing through a Rectifier and a Voltage Regulator. If it is the above transceiver process, the Tag end needs to have the output current of the voltage regulator to supply the Digital State Machine during the stages of Reply sending, ACK listening, and subsequent sending of information such as PC / XPC and EPC, which poses certain requirements for the power supply of the Tag.

[0064] For the case of using On-off keying (OOK) sequences to distinguish different users, multi-user multiplexing is achieved by means of sequence superposition. Considering that the receiver of the OOK modulation waveform is relatively simple and generally can only be received by an envelope receiver, some very complex frequency-domain multiple access technologies cannot be used. The main means is to perform multiple access for different users through Time Division Multiple Access (TDMA).

[0065] However, in some scenarios, such as during initial access or interrogation, due to the existence of multi-user conflicts, it is necessary to allow multiple users to multiplex the same time-frequency resources for transmission to reduce the probability of blocking. For the OOK modulation waveform, it is challenging to correctly distinguish multiple users and ensure their respective performances. This is mainly because it is difficult to achieve multi-user multiplexing through sequence superposition, it is difficult to meet the orthogonality of sequences between users, and due to the existence of the near-far effect, the performance is very poor.

[0066] To solve the above problems, an embodiment of the present application proposes a resource transmission method for multi-user OOK, enabling OOK modulation to meet the requirements of multiple users for multiplexing and effectively eliminating the near-far effect and non-orthogonal interference problems between users.

[0067] The following will combine the accompanying drawings and, through specific embodiments and their application scenarios, elaborate in detail on the information transmission method provided by the embodiments of the present application.

[0068] See Figure 1 , Figure 1 which is a flowchart of the information transmission method provided by the embodiments of the present application and is executed by the first transmitting end. As Figure 1 shown, it includes the following steps:

[0069] Step 101: Determine one transmission resource from the K transmission resources in a transmission occasion (TO) as the target transmission resource. Among them, the K transmission resources are used to transmit data information of different transmitting ends, and each transmission resource is configured with a pilot (Reference Signal, RS) transmission position and a data (DATA) transmission position. The RS transmission positions among the K transmission resources do not overlap with each other, and K is an integer greater than 1.

[0070] The above-mentioned transmitting end may refer to the party that needs to transmit information, and the receiving end refers to the corresponding party that receives the transmitted information. Exemplarily, the transmitting end may refer to the Tag end in RFID, and the receiving end is a device on the base station side or the reader side, such as a reader. For the convenience of introduction, the embodiments of the present application mainly use the Tag end and the Reader end as examples for illustration.

[0071] The embodiments of the present application are applicable to the scenario where multiple users multiplex overlapping transmission resources in the same TO for information transmission. That is to say, in the embodiments of the present application, there are multiple transmitting ends multiplexing the same time-frequency resources to transmit information to the receiving end. The above-mentioned first transmitting end may refer to any one of the multiple transmitting ends.

[0072] In the prior art, when multiple Tags transmit in the original one transmission occasion TO, conflicts and collisions will occur, resulting in the receiving end being unable to receive normally.

[0073] The solution proposed in the present application allows the receiving end to decode the information of multiple Tags in a transmission occasion TO and, by designing the frame structure of the transmission resources, achieves the purpose of minimizing information loss caused by conflicts and collisions. Since there is a possibility that the information of multiple Tags is uploaded in the same TO transmission occasion, a series of problems caused by non-orthogonal transmission need to be solved, such as interference problems.

[0074] Specifically, in the embodiments of the present application, by designing the frame structure of the uplink data transmission resources in a single TO, each transmission resource includes an RS transmission position and a DATA transmission position, and the RS transmission positions of each transmission resource are staggered so that the RS transmission positions of each transmission resource do not overlap, that is, there is no overlap between the RS transmission positions of any two transmission resources in a single TO, and this part of the position is used to transmit the pilot information or preamble of the user, such as the random serial number of the Tag end. The DATA transmission position is used to transmit the data or information that the user really needs to transmit, such as transmitting the identification information of the Tag.

[0075] It should be noted that the receiving end can negotiate with the sending end that there are K candidate transmission resources in a single TO that can be used to transmit information, and at least a part of the K candidate transmission resources overlap in time / frequency. Among them, each transmission resource in a single TO can be used to transmit the data information of a sending end, and different transmission resources transmit the data information of different sending ends; the RS transmission position and the DATA transmission position of each transmission resource can be pre-configured by the receiving end and notified to the sending end, or negotiated and agreed upon by the receiving end and the sending end.

[0076] In the embodiments of the present application, after the first sending end determines that there are K transmission resources in a single TO, it can first determine one of them as the target transmission resource for transmitting its information. Specifically, it can determine how the Tag selects one resource from the K candidate resources based on some pre-established rules, such as randomly selecting or selecting with reference to the wireless link attributes.

[0077] Optionally, there is a guard interval between the RS transmission positions of the K transmission resources.

[0078] In some embodiments, in order to ensure to a greater extent that there is no collision between the resources transmitted at the same time, the receiving end can configure a guard interval (GuardPeriod) to be reserved between the RS transmission positions of multiple transmission resources in the same TO. The specific interval size can be comprehensively determined based on factors such as the coverage distance and the non-ideal deviation of the device.

[0079] Optionally, the DATA transmission positions of some or all of the K transmission resources overlap.

[0080] That is, in some embodiments, the RS parts of multiple candidate transmission resources in the same TO are orthogonal to each other without overlap, while the data parts overlap in time / frequency at least in part of the resources.

[0081] Exemplarily, such as Figure 2As shown, User 1, User 2, and User 3 use 3 transmission resources in TO to transmit information once. The RS parts of these 3 transmission resources do not overlap in the time domain, and a GuardPeriod can be left between any two of them. The data parts of these 3 transmission resources overlap in the time domain. The waveform of the data part received at the receiving end is the superposition of the waveforms of these 3 users. In this way, not only can multi-user multiplexing of the same time transmission resources be realized, enabling multi-user information to be transmitted in the same transmission opportunity, but also by designing mutually orthogonal RS parts, the occurrence of resource collisions can be effectively reduced.

[0082] Optionally, step 101 includes:

[0083] Randomly select one transmission resource from the K transmission resources as the target transmission resource;

[0084] Or, based on the wireless link attributes of the first sending end, select one transmission resource from the K transmission resources as the target transmission resource.

[0085] That is, in some embodiments, the sending end can randomly select one transmission resource from the K transmission resources as its target transmission resource. For example, the Tag end can select a corresponding target transmission resource according to the random number generated in the inventory mode. In this way, different sending ends can select different transmission resources according to different random numbers, reducing the possibility of resource collisions.

[0086] In other embodiments, the sending end can determine a suitable transmission resource as its target transmission resource according to its wireless link attributes, such as coverage distance and other coverage conditions, channel quality, etc. For example, each sending end can select different transmission resources according to the coverage distance, and those with similar coverage distances can select the same transmission resource. In this way, the near-far effect can be effectively eliminated and the transmission performance can be improved.

[0087] Step 102: Based on the RS transmission position and DATA transmission position configured for the target transmission resource, carry the RS information of the first sending end at the RS transmission position of the target transmission resource, and carry the data information of the first sending end at the DATA transmission position of the target transmission resource.

[0088] After determining the target transmission resources to be used, the first transmitting end may determine the RS transmission position and the DATA transmission position of the target transmission resources. The information to be transmitted by the first transmitting end is also divided into an RS part and a DATA part. Accordingly, the RS information to be transmitted by the first transmitting end can be carried at the RS transmission position of the target transmission resources, and the DATA part information of the first transmitting end can be carried at the DATA transmission position of the target transmission resources. Finally, the information of the first transmitting end can be transmitted through the target transmission resources.

[0089] Among them, for the information transmission of both the RS part and the DATA part, OOK modulation or some simple single-carrier modulation schemes such as Binary Phase Shift Keying (BPSK), Quadrature Phase Shift Keying (QPSK), etc. can be used.

[0090] Optionally, the data information includes the transmitting end identification information.

[0091] In some embodiments, the DATA transmission position part of the target transmission resources can be used to transmit the transmitting end identification information, that is, the data transmission part can carry all or part of the information related to the unique Tag identification. Of course, other relevant information can also be carried in the DATA transmission part for transmission according to actual transmission requirements.

[0092] Step 103: Transmit the data information of the first transmitting end to the receiving end by using the target transmission resources.

[0093] After determining the transmission information carried in the target transmission resources, the information can be transmitted to the receiving end by using the target transmission resources.

[0094] In the embodiments of the present application, since the RS transmission positions of all the transmission resources in one TO do not overlap with each other, during the uplink transmission, the RS parts of each transmission resource are orthogonal to each other without overlap. When different Tags select different transmission resources, the RS information will be transmitted at different times, so resource collisions will not occur.

[0095] According to the above embodiments of this embodiment, such as Figure 2As shown, in practical applications, when different Tags select different candidate resources according to random numbers, RS can be transmitted at different times, and data can be transmitted on the same time-frequency resource; when different Tags select the same candidate resource according to random numbers, resource collisions will occur. Compared with the traditional situation where multiple Tags will definitely collide if they want to transmit simultaneously during the same TO transmission opportunity, the solution of the embodiment of the present application can better reduce the collision probability.

[0096] In the inventory process, generally, three steps of Select - Inventory - Access are followed; during the Inventory process, the Tag will send the RN16 response to the Reader. This inventory process can adopt the uplink data transmission structure as introduced in the embodiment of the present application as Figure 2 shown to send the response data, and the usage method of this data transmission structure during the Tag inventory process is as Figure 3 shown.

[0097] Among them, the Query command starts an inventory action, and the repeated QueryRep corresponds to reducing the number of Slots of the Tag label. As Figure 3 shown, the multiplexing of multiple users can be utilized to transmit the response information of multiple users in the Response, thereby reducing the probability of multiple user collisions (blocking) and improving the inventory efficiency. Figure 3 RS1, RS2, RS3, and RS4 in

[0098] can be a symbol (also called a tone) or a sequence (a sequence composed of random numbers).

[0099] See Figure 4 , Figure 4 which is a flowchart of another information transmission method provided by an embodiment of the present application and is executed by a receiving end. As shown in Figure 4 the following steps are included:

[0100] Step 401: Receive the total data signals of N sending ends on K transmission resources in one TO. Among them, each of the transmission resources is configured with an RS transmission position and a DATA transmission position, and the RS transmission positions among the K transmission resources do not overlap with each other. The RS transmission positions of the K transmission resources carry RS information of different sending ends respectively, and the DATA transmission positions of the K transmission resources carry data information transmitted by different sending ends respectively. K is an integer greater than 1, and N is a positive integer less than or equal to K.

[0101] This embodiment, as the corresponding receiving-end side implementation manner in the embodiment shown in Figure 1 can refer to the relevant introduction in the foregoing embodiment shown in Figure 1 For the sake of avoiding repetition, it will not be elaborated here.

[0102] It should be noted that each transmission resource in one TO can be used to transmit the data information of one sending end, and the data information transmitted by different transmission resources is that of different sending ends. In practical applications, some or all of the K transmission resources can be used to transmit the data information of the sending ends. Therefore, at most K sending ends' data information can be transmitted in one TO, that is, the data information of the above-mentioned N sending ends. The data information of the N sending ends reaches the receiving end through the K transmission resources, and the receiving end then receives the total data signal including the data information of the N sending ends.

[0103] Optionally, there is a guard interval between the transmission positions of the K transmission resources.

[0104] Optionally, there is an overlap in the DATA transmission positions of some or all of the K transmission resources.

[0105] Optionally, the data information includes sending end identification information.

[0106] The above optional implementation manners can also refer to the relevant introduction in the foregoing embodiment shown in Figure 1 and can achieve the same technical effects. For the sake of avoiding repetition, it will not be elaborated here.

[0107] Optionally, after step 401, the method further includes:

[0108] The successive interference cancellation (SIC) algorithm is used to perform multi-user demultiplexing (MUD) on the total data signal to obtain the data information transmitted by each sending end.

[0109] That is, in some embodiments, the SIC algorithm can be used to perform multi-user demultiplexing MUD on the total data signal to eliminate interference between users and obtain the transmission information of each sending end user.

[0110] Specifically, for the reception of the Reader end, the Reader end can respectively detect the RS parts on K candidate transmission resources in a transmission opportunity TO, determine how many Tags are transmitting according to the signal strength of the RS parts, and then use the SIC reception algorithm to perform MUD to eliminate interference between users and decode the information of each Tag. Specifically, the user signal with the strongest signal can be decoded first, and then the decoded user signal can be subtracted from the total signal, and then the user signal with the second-strongest signal can be decoded from the remaining signal, and so on, decoding each user signal in turn.

[0111] Through this implementation method, it is possible to ensure accurate decoding of the multiplexed multi-user information and obtain better user information quality.

[0112] Optionally, the use of the successive interference cancellation SIC algorithm to perform multi-user demultiplexing MUD on the total data signal to obtain the data information transmitted by each sending end includes:

[0113] Estimate the channel response and delay information of each sending end according to the RS information carried in the RS transmission position of each transmission resource;

[0114] According to the signal strength of the RS information received at the RS transmission position of each transmission resource, and according to the channel response and delay information of each sending end, decode the data information transmitted by each sending end from the total data signal in turn.

[0115] In some more specific embodiments, from the perspective of the receiving end, MUD requires SIC to eliminate interference between users, and its specific process is as follows:

[0116] 1) Since the RS sequences of users are orthogonal, the receiving end can estimate the channel responses H1, H2, H3,... of each user and the delay information t1, t2, t3... of each user based on the RS sequences of each user. The delay information is as Figure 5As shown in the figure. Assume that each user is named User 1, User 2, User 3,... in order of signal strength. Specifically, the signal strength ranking among users can be determined by detecting the signal strength of the RS part of each user.

[0117] 2) According to the channel response H1 and delay information t1 of User 1, decode the signal of the strongest User 1 from the total signal, and the user to which the signal belongs can be determined according to the unique identification information carried in the DATA part of the decoded signal;

[0118] 3) Reconstruct the signal of User 1 according to the channel response H1 and delay information t1 of User 1, and subtract the signal of User 1 from the total signal;

[0119] 4) In the remaining signal, decode the signal of User 2 with the second-strongest signal according to the channel response H2 and delay information t2 of User 2, and the user to which the signal belongs can be determined according to the unique identification information carried in the DATA part of the decoded signal;

[0120] 5) Reconstruct the signal of User 2 according to the channel response H2 and delay information t2 of User 2, and subtract the signal of User 2 from the current remaining signal;

[0121] 6) In the remaining signal, decode the signal of User 3 according to the channel response H3 and delay information t3 of User 3, and the user to which the signal belongs can be determined according to the unique identification information carried in the DATA part of the decoded signal;

[0122] 7)..., and so on, decoding the signals of each user in turn.

[0123] Through this implementation method, the information of each user transmitted in the same TO can be decoded well, ensuring the signal decoding quality.

[0124] It should be noted that, for better application of the embodiments of the present application, the Automatic Gain Control (AGC) range at the receiving end should be sufficient to adapt to the signal strength of all users, otherwise the signals of some users may be blocked.

[0125] The following combines Figure 6 , taking the process schematic of using SIC for MUD in the case of specifically transmitting the information of 2 users as an example to illustrate the implementation method of the embodiments of the present application. It is assumed here that the data part is Manchester encoded. The general process is as follows:

[0126] 1) The sending end transmits the signals of User1 and User2 in one TO, as shown in part (a) of Figure 6 , where the RS parts of the two do not overlap, and the data parts overlap in time.

[0127] 2) The receiving end receives the signals of User1 and User2 transmitted in one TO, and the superposition of the two signals and the resulting total signal are as Figure 6 shown in part (b) thereof.

[0128] 3) Since the signal strength of the RS part of User2 is higher than that of User1, the receiving end first decodes the signal of User2 and obtains the signal of User2 through User2 signal decision (User2 Decision). Specifically, according to the signal component strength at each position in the DATA part, the position with the maximum signal component strength is determined as the superposition of the signal components of User1 and User2, the position with the second highest signal component strength is determined as the signal component of User2, and the position with the minimum signal component strength is determined as the signal component of User1. Thus, the positions of the signal components of User2 can be determined. The decoding process is as Figure 6 shown in part (c) thereof, where the user identity of User2 can be determined through the unique identification information carried in the decoded signal of User2.

[0129] 4) Reconstruct the signal of User2 and subtract the signal of User2 from the total signal.

[0130] 5) Obtain the signal of User1 through User1 signal decision (User1 Decision). Similarly, the user identity of User1 can be determined through the unique identification information carried in the decoded signal of User1.

[0131] The following combines Figure 7 , taking the process schematic of using SIC for MUD in the case of specifically transmitting the information of 3 users as an example to illustrate the implementation manner of the embodiments of the present application. The general process is as follows:

[0132] 1) The transmitting end transmits the signals of User1, User2, and User3 in one TO, as Figure 7 shown in part (a) thereof, where the RS parts of the three do not overlap with each other, and the data parts overlap in time.

[0133] 2) The receiving end receives the signals of User1, User2, and User3 transmitted in one TO, and the superposition of the three signals and the resulting total signal are as Figure 7 shown in part (b) thereof.

[0134] 3) Since the RS part signal strength of User1 is the highest, the receiving end first decodes the signal of User1 and obtains the signal of User1 through User1 signal decision. Specifically, according to the signal component strength at each position in the DATA part, it is determined that the position with the maximum signal component strength is the superposition of the signal components of User1, User2, and User3, the position with the second highest signal component strength is the superposition of the signal components of User1 and User2, the position with the third highest signal component strength is the superposition of the signal components of User1 and User3, the position with the fourth highest signal component strength is the superposition of the signal components of User2 and User3, the position with the fifth highest signal component strength is the signal component of User1, the position with the sixth highest signal component strength is the signal component of User2, and the position with the minimum signal component strength is the signal component of User3. Thus, the positions of the signal components of User1 can be determined. The decoding process is as shown in part (c) of Figure 7 and the user identity of User1 can be determined through the unique identification information carried in the decoded signal of User1.

[0135] 4) Subtract the signal of User1 from the total signal to obtain the User2+User3 signal.

[0136] 5) Decode the signal of User2 and obtain the signal of User2 through User2 signal decision. Specifically, according to the signal component strength at each position in the DATA part, it is determined that the position with the maximum signal component strength is the superposition of the signal components of User2 and User3, the position with the second highest signal component strength is the signal component of User2, and the position with the minimum signal component strength is the signal component of User3. Thus, the positions of the signal components of User2 can be determined. Similarly, the user identity of User2 can be determined through the unique identification information carried in the decoded signal of User2.

[0137] 6) Subtract the signal of User2 from the User2+User3 signal and obtain the User3 signal through User3 signal decision. Similarly, the user identity of User3 can be determined through the unique identification information carried in the decoded signal of User3.

[0138] In addition, in addition to using the Figure 7 hard decision method shown in, soft decision can also be performed based on some coding methods and better performance can be obtained.
