[0002] Backscatter communication is a method of transmitting information by modulating radio frequency signals from other devices or the environment. A traditional backscatter communication system includes a reader and a tag.

The modulated incident signal is then reflected back to the reader to transmit the tag's information.

[0003] However, according to the above method, since the tag can only receive the incident signal if it is within the coverage area of ​​the incident signal sent by the reader, and thus the modulated incident signal can be reflected back to the reader, the range of backscatter communication is relatively small.

[0036] The resource allocation method, apparatus, communication equipment, system, and storage medium provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

[0037] Backscatter communication refers to the transmission of information by a backscatter communication device using radio frequency signals from other devices or the environment for signal modulation. The backscatter communication device can be any one of the following: a to c.

[0038] a. Backscatter communication devices in traditional Radio Frequency Identification (RFID) are generally single tags and belong to Passive Internet of Things (Passive-IoT) devices;

[0039] b. Semi-passive tags, which have a certain amplification capability in downlink reception or uplink reflection;

[0040] c. Tags with active sending capability (i.e., active tags) can send information to the reader without relying on the reflection of the incident signal.

[0041] The following description, in conjunction with the accompanying drawings, provides an exemplary illustration of the method for signal transmission between the reader and the tag in backscatter communication.

[0042] For example, suppose that when a tag needs to send '1', the tag reflects the incident signal, and when the tag needs to send '0', it does not reflect the signal. Then, as... Figure 2 As shown, after receiving the incident signal 23 sent by the reader 21, the tag 22 can adjust the impedance inside the tag 22 to change the amplitude, frequency, phase, etc. of the incident signal 23, thereby modulating the signal and reflecting the modulated incident signal 24 back to the reader 21 to transmit the information of the tag 22.

[0043] Specifically, the reflected signal S out (t) and incident signal S in The relationship between (t) can be expressed by the following formula (1):

[0044]

[0045] Wherein, Γ is the reflection coefficient of the circuit in the tag, and the reflection coefficient Γ can be characterized by the following formula (2):

[0046]

[0047] Where Z0 is the characteristic impedance of the antenna and Z1 is the load impedance.

[0048] It can be seen that the reflection coefficient Γ of the circuit in the tag can be controlled by adjusting the internal impedance, thereby achieving amplitude modulation, frequency modulation or phase modulation of the incident signal.

[0049] Figure 3 A schematic diagram illustrating information transmission between the reader and the tag is shown, such as... Figure 3 As shown, during the information transmission between the reader and the tag, the reader's workflow includes selection, inventory, and access. Selection refers to the process where the reader chooses a tag group for subsequent inventory or to conduct encrypted challenge on a tag group for subsequent verification. Selection includes selection commands and challenge commands. Inventory is the process where the reader identifies the tag. The reader initiates the inventory process by transmitting a query command in one of four sessions. One or more tags may respond. The reader detects individual tag responses. The inventory process is executed in one and only one session and includes multiple commands. Access is the process where the reader transacts with a single tag (reading, writing, verifying, or otherwise participating). The reader individually and uniquely identifies the tag before access, and access includes multiple commands.

[0050] During the information transmission between the reader and the tag, the instructions for the reader's operation are shown in Tables 1 and 2 below:

[0051] Table 1

[0052]

[0053] Table 2

[0054]

[0055]

[0056]

[0057] like Figure 3 As shown, during the information transmission process between the reader and the tag, the tag's states include: ready, mediating, responding, acknowledging, open, protected, and destroyed. A detailed description of each tag state is shown in Table 3 below:

[0058] Table 3

[0059]

[0060]

[0061] Currently, in inventory mode, the protocol design of Ultra High Frequency (UHF) RFID requires the reader to send a query command, the tag to respond and generate a 16-bit random number, and then the reader sends this sequence to the tag via an ACK command. The tag then sends the relevant data back to the reader. In existing backscatter communication systems, the reader can typically only receive the backscatter signal from one tag at a time. For example, in the RFID inventory process, when the reader sends a control command to start the inventory process, it indicates a value Q, and the tag locally generates a {0, ..., 2} backscatter signal. Q From the values ​​in {-1}, a random value q is selected. The tag with the current random value of 0 will respond to the reader's control command and transmit a backscatter signal, while the tag with the current random value that is not 0 will not transmit a backscatter signal for the time being. After completing communication with the tag with the random value of 0, the reader can continue to send control commands (e.g., queryRep), such as instructing the tag to decrement the generated random value by 1. The tag with the random value reduced to 0 will respond to the control command and transmit a backscatter signal.

[0062] The above process is a random multiple access process. Because multiple tags may generate the same random number locally, this can lead to multiple tags simultaneously transmitting backscattered signals at a certain moment. In this case, the reader is highly unlikely to detect any tag's backscattered signal and will not provide feedback to the tag indicating that a backscattered signal has been received. Consequently, these tags will continue to receive control commands from the reader, waiting for a new opportunity for backscattered transmission. Therefore, when sending control commands, the reader should select a reasonable Q value and gradually adjust the Q value during the inventory process to reduce the probability of collisions during communication with multiple tags. However, this also means that the time to complete communication with multiple tags will increase.

[0063] Existing backscatter communication systems support communication between the reader and the tag. However, since the tag can only receive the incident signal sent by the reader if it is within the coverage area of ​​the signal, and thus can reflect the modulated incident signal back to the reader, the range of backscatter communication is relatively small. Moreover, as new terminals will be introduced in future 5G NR-supported backscatter communication systems, the rational allocation of uplink and downlink resources among the reader, terminal, and tag is an urgent problem to be solved.

[0064] To address the aforementioned issues, this application provides a resource allocation method. In this method, a terminal can receive configuration information from a reader; the configuration information is used to configure resources related to the transmission of at least one tag. Through this method, the terminal can transmit CW and / or commands to at least one tag based on the configuration information received from the reader, or receive feedback information regarding the transmission of at least one tag. This allows the terminal to participate in tag-related transmissions. Because the terminal's participation is added to backscatter communication, the scope of backscatter communication can be expanded. Furthermore, it also enables communication in a 5G NR-supported backscatter communication system with terminal participation.

[0065] This application provides a resource allocation method. Figure 4 A flowchart illustrating the resource allocation method provided in an embodiment of this application is shown. Figure 4 As shown, the resource allocation method provided in this application embodiment may include the following steps 401 and 402.

[0066] Step 401: The terminal receives configuration information from the network-side device.

[0067] In this embodiment of the application, the above configuration information is used to configure resources related to the transmission of at least one backscatter communication device.

[0068] Optionally, in the embodiments of this application, the backscatter communication device can be any of the following: a passive Internet of Things (IoT) device, an ambient IoT device, or a tag.

[0069] Optionally, in this embodiment of the application, the above configuration information may include at least one of the following: a first resource, a second resource, and a first control command.

[0070] In this embodiment of the application, the first resource is used to transmit CW and / or commands to each of the at least one backscatter communication device.

[0071] In this embodiment of the application, the second resource is used to transmit feedback information from each of the aforementioned backscatter communication devices.

[0072] In this embodiment of the application, the first control command is used to indicate any one of the following: uplink resources for transmitting feedback information of each of the aforementioned backscatter communication devices; and the command type of the command transmitted to each of the backscatter communication devices.

[0073] Optionally, in this embodiment of the application, the terminal can receive the first control command through a low-power wake-up receiver (LP-WUR).

[0074] In this embodiment of the application, since the above configuration information may include at least one of the first resource, the second resource and the first control command, the terminal can participate in the transmission related to at least one backscatter communication device in different ways according to different configuration information, thereby improving the flexibility of backscatter communication.

[0075] Optionally, in this embodiment of the application, CW can be used to charge the backscatter communication device so that the backscatter communication device can perform directional scatter communication.

[0076] Optionally, in the embodiments of this application, the duration of the CW transmitted to each of the above-mentioned backscatter communication devices may be fixed or may be variable.

[0077] Optionally, in this embodiment of the application, when the duration of the CW transmitted to each of the aforementioned backscatter communication devices is not fixed, the duration of the CW may be related to the command type of the command transmitted to each of the backscatter communication devices.

[0078] For example, the duration of the CW corresponding to the inventory command is greater than or equal to the duration of the CW corresponding to the query command, thereby increasing the flexibility of the way backscatter communication devices are charged.

[0079] Optionally, in this embodiment of the application, the feedback information may include at least one of the following: identification information; status information; control information; data; electronic product code information.

[0080] Optionally, in this embodiment of the application, the above-mentioned identification information may be a 16-bit random value that temporarily identifies the backscatter communication device during the query process of backscatter communication.

[0081] Optionally, in the embodiments of this application, the above-mentioned status information can be used to indicate the status of the backscatter communication device. For example, the status information can indicate the ready status, response status, or destruction status of the backscatter communication device.

[0082] Optionally, in this embodiment of the application, each backscatter communication device may correspond to an electronic product code, and the electronic product code information may be used to indicate the corresponding backscatter communication device.

[0083] In this embodiment, since the feedback information may include at least one of identification information, status information, control information, data, and electronic product code information, different information for each backscatter communication device can be transmitted through the second resource, thereby improving the flexibility of feedback from the backscatter communication device.

[0084] Optionally, in this embodiment of the application, the feedback information transmitted on the second resource may include any of the following:

[0085] (1.1) Feedback information from a backscatter communication device;

[0086] (1.2) Feedback information received by the terminal from at least two backscatter communication devices within a first preset time interval.

[0087] Optionally, in this embodiment of the application, when both the first resource and the second resource are semi-static resources:

[0088] If the feedback information transmitted on the second resource includes the above (1.1), then each first resource corresponds to one second resource, so that the feedback information of each backscatter communication device can be transmitted in a timely manner; if the feedback information transmitted on the second resource includes the above (1.2), then multiple first resources correspond to one second resource, so that the number of times feedback information is transmitted can be reduced and transmission resources can be saved.

[0089] Optionally, in this embodiment of the application, the first preset time interval can be predefined, preconfigured, or agreed upon by a protocol.

[0090] In this embodiment of the application, since the feedback information transmitted on the second resource may include (1.1) or (1.2) as described above, the flexibility of transmitting feedback information on the second resource can be improved.

[0091] Optionally, in this embodiment, the first resource may be associated with the second resource.

[0092] Optionally, in this embodiment, the association between the first resource and the second resource may include at least one of the following:

[0093] (2.1) The cycle of the second resource is N times the cycle of the first resource, where N is a positive number;

[0094] (2.2) The time interval between the first resource and the second resource is the first time interval.

[0095] Optionally, in the embodiments of this application, when the first resource and the second resource are related as described in (2.1) above, the first resource and the second resource have a periodic relationship, and the period of the second resource can be 0.5 times, 1 times, or 2 times the period of the first resource, etc.

[0096] For example, the cycle of the second resource is twice the cycle of the first resource, meaning the cycle of the second resource is equal to the cycle of the first resource.

[0097] In this embodiment of the application, since the relationship between the first resource and the second resource may include at least one of (2.1) and (2.2) above, the flexibility of the relationship between the first resource and the second resource can be improved.

[0098] Optionally, in embodiments of this application, the first time interval may include any of the following:

[0099] (3.1) The time interval between the start time of the first resource and the end time of the second resource;

[0100] (3.2) The time interval between the end time of the first resource and the start time of the second resource.

[0101] In this embodiment of the application, since the first time interval may include (3.1) or (3.2) above, the flexibility of the first resource and the second resource can be further improved by using different first time intervals.

[0102] In this embodiment, since the first resource is related to the second resource, that is, the resource for transmitting CW and / or commands to each of the backscatter communication devices is related to the resource for transmitting feedback information of each of the backscatter communication devices, the conflict of transmission resources can be reduced, thereby improving the success rate of transmission.

[0103] Optionally, in this embodiment of the application, the first control command may be carried by downlink control information (DCI).

[0104] Optionally, in this embodiment of the application, the network-side device can send a first control command to the terminal via DCI to indicate to the terminal the uplink resources for transmitting feedback information of each of the aforementioned backscatter communication devices, or the command type of the command transmitted to each of the backscatter communication devices.

[0105] In this embodiment of the application, since the first control command can be carried through DCI, there is no need to transmit the first control command separately, thereby saving transmission resources.

[0106] Optionally, in embodiments of this application, the first control command may include at least one of the following: resource allocation indication; time interval indication; command type indication.

[0107] In this embodiment of the application, the resource allocation indicator is used to indicate the resource allocation for transmitting CW and / or commands.

[0108] In this embodiment of the application, the time interval indicator is used to indicate the second time interval between the end time of the time unit where the first control command is located and the start time of the transmission of the above feedback information.

[0109] Optionally, in the embodiments of this application, the feedback information of each backscatter communication device is carried through a Physical Uplink Control Channel (PUCCH) or a Physical Uplink Shared Channel (PUSCH).

[0110] In this embodiment of the application, since the feedback information of each backscatter communication device can be carried through PUCCH or PUSCH, the flexibility of transmitting feedback information can be improved.

[0111] Optionally, in this embodiment of the application, the second time interval may be greater than or equal to a preset delay, which is related to the processing capability of the terminal and may also be referred to as the processing delay.

[0112] Optionally, in this embodiment of the application, the preset delay can be predefined, preconfigured, or agreed upon by the protocol.

[0113] In this embodiment of the application, since the second time interval can be greater than or equal to the preset delay, it can be ensured that after the terminal receives the first control command, it has enough processing time to obtain feedback information and start transmitting feedback information from the backscatter communication device, thereby ensuring that feedback information is transmitted according to the instructions of the network-side device.

[0114] In this embodiment of the application, the command type indicator is used to indicate the command type of the command currently being transmitted by the terminal.

[0115] For a detailed description of the command types mentioned above, please refer to the relevant descriptions in the related technologies mentioned above. To avoid repetition, they will not be repeated here.

[0116] In this embodiment of the application, since the first control command may include at least one of resource allocation indication, time interval indication and command type indication, different first control commands can be used to give different indications for transmission with at least one backscatter communication device, thereby further improving the flexibility of backscatter communication.

[0117] Optionally, in this embodiment of the application, when the first control command includes the above-mentioned resource allocation instruction, the third time interval is greater than or equal to the second preset time interval.

[0118] In this embodiment of the application, the third time interval is the time interval between transmitting CW and commands to each of the aforementioned backscatter communication devices.

[0119] Optionally, in this embodiment of the application, the second preset time interval can be predefined, preconfigured, or agreed upon by a protocol.

[0120] In this embodiment of the application, since the time interval between transmitting CW and command to each backscatter communication device is greater than or equal to the second preset time interval, it can be ensured that each backscatter communication device can receive CW and command, thereby avoiding the backscatter communication device being unable to perform backscatter communication.

[0121] Step 402: The terminal transmits CW and / or commands to at least one backscatter communication device according to the configuration information, or receives feedback information transmitted by at least one backscatter communication device.

[0122] Optionally, in the embodiments of this application, the above-mentioned CW and / or commands may be indicated by network-side devices.

[0123] Optionally, in this embodiment of the application, if the above configuration information does not include the first control command, after receiving the configuration information, the terminal can receive the feedback information sent by the backscattering device on the corresponding resource and forward the feedback information of each backscattering communication device to the network side device; that is, the terminal can directly transmit the feedback information received from at least one backscattering communication device to the network side device on the available uplink resources based on the configuration information.

[0124] In the resource allocation method provided in this application embodiment, the terminal can transmit CW and / or commands to at least one backscatter communication device according to the configuration information received from the network-side device, or receive feedback information transmitted by at least one backscatter communication device. In this way, the terminal can participate in the transmission related to the backscatter communication device. Since the participation of the terminal is added to the backscatter communication, the scope of the backscatter communication can be expanded.

[0137] In this embodiment of the application, the above-mentioned resource allocation indication is used to indicate: resource allocation for transmitting CW and / or commands.

[0138] In this embodiment of the application, the aforementioned time interval indicator is used to indicate the second time interval between the end time of the time unit in which the first control command is located and the start time of the transmission of the aforementioned feedback information.

[0139] Optionally, in this embodiment of the application, the second time interval may be greater than or equal to a preset delay, which is related to the processing capability of the terminal and may also be referred to as the processing delay.

[0140] In this embodiment of the application, the command type indicator is used to indicate the command type of the command currently being transmitted by the terminal.

[0141] Optionally, in this embodiment of the application, when the first control command includes the above-mentioned resource allocation instruction, the third time interval is greater than or equal to the second preset time interval.

[0142] The third time interval is the time interval between transmitting CW and commands to each of the aforementioned backscatter communication devices.

[0143] Step 502: The network-side device transmits CW and / or commands to at least one backscatter communication device according to the configuration information, or receives feedback information transmitted by at least one backscatter communication device.

[0144] Optionally, in this embodiment of the application, the network-side device may directly transmit CW and / or commands to the at least one backscatter communication device, or it may first transmit CW and / or commands to the terminal, and then transmit CW and / or commands to the at least one backscatter communication device through the terminal on the corresponding resources.

[0145] Optionally, in this embodiment of the application, the network-side device can directly receive feedback information from the above-mentioned at least one backscattering device.

[0146] Optionally, in this embodiment of the application, the network-side device can receive feedback information transmitted by the at least one backscattering device on the corresponding resources through the terminal. That is, the at least one backscattering device can first transmit the feedback information to the terminal, and then the terminal can transmit the feedback information to the network-side device, thereby enabling the terminal to act as a relay node to expand the range of backscattering communication.

[0147] Optionally, in this embodiment of the application, after receiving feedback information from at least one backscatter communication device, the network-side device can use the feedback information to know the content that each backscatter communication device needs to transmit.

[0148] Optionally, in this embodiment of the application, backscatter communication can be completed after the network-side device receives feedback information from the backscatter communication device.

[0149] For other descriptions in the embodiments of this application, please refer to the relevant descriptions in the above terminal-side embodiments. To avoid repetition, they will not be repeated here.

[0150] In the resource allocation method provided in the embodiments of this application, the network-side device can send configuration information to the terminal for configuring resources related to the transmission of at least one backscatter communication device, and can transmit CW and / or commands to at least one backscatter communication device according to the configuration information, or receive feedback information transmitted by at least one backscatter communication device. In this way, the network-side device can instruct the terminal to participate in the transmission related to the backscatter communication device. Since the terminal can participate in traditional backscatter communication, the scope of backscatter communication can be expanded.

[0151] The resource allocation method provided in this application embodiment will be described in detail below with reference to the accompanying drawings, taking a backscattering device as an example.

[0152] Figure 6 This illustrates a scenario in which the resource allocation method provided in this application is applied, such as... Figure 6 As shown, network-side device 61 transmits CW and / or commands to tag 62. After receiving the CW and / or commands, tag 62 transmits feedback information to terminal 63. Terminal 63 then transmits the received feedback information from tag 62 back to network-side device 61. The first resource is the downlink (DL) resource for the CW and / or commands transmitted by network-side device 61 to tag 62, and the second resource is the uplink (UL) resource for transmitting the feedback information from tag 62.

[0153] Optionally, in the embodiments of this application, in Figure 6 In the application scenario shown, if both the first and second resources configured on network-side device 61 are semi-static resources, then as follows: Figure 7 As shown, each DL resource corresponds to one UL resource, or multiple DL resources correspond to one UL resource. That is, after receiving feedback information from multiple tags, terminal 63 transmits all feedback information together to network-side device 61. Both DL and UL resources are periodic, with K1 being the time interval between the end of the first resource and the start of the second resource. After network-side device 61 transmits CW and / or commands to tag 62 through the first resource, tag 62 can charge via the CW and perform backscatter communication. Terminal 63 receives the tag's feedback information on the backscatter communication (BSC) channel and, after time K1, integrates (or does not integrate) the received feedback information using the UL resource before transmitting it to network-side device 61.

[0154] Optionally, in the embodiments of this application, in Figure 6In the application scenario shown, if both the first and second resources configured by network-side device 61 are dynamic resources, then network-side device 61 can dynamically schedule DL and UL resources through DCI. Specifically, the time interval between the transmission of CW and commands by network-side device 61 is greater than or equal to a specific time interval T1. The duration of CW is fixed or variable. The first control command can be used to instruct terminal 63 to report the start time of the UL resource containing backscattered content to network-side device 61, or to instruct the command type of the command sent by network-side device 61 to tag 62. Network-side device 61 can instruct terminal 63 through DCI to transmit the received feedback information from tag 62 at the corresponding UL resource location. If terminal 63 receives the first control command, terminal 63 can know the expected feedback information from tag 62 and determine whether to integrate and send subsequently received feedback information. When terminal 63 receives the first control command, terminal 63 does not need additional instructions; when terminal 63 knows the type of the first control command through DCI, terminal 63 needs additional instructions. If terminal 63 does not receive the first control command, terminal 63 cannot predict the feedback information of tag 62. Therefore, terminal 63 can use a transparent transmission method to directly transmit the feedback information to network-side device 61 on available UL resources after receiving the feedback information from tag 62.

[0155] Figure 8 This illustrates another scenario in which the resource allocation method provided in the embodiments of this application is applied, such as... Figure 8 As shown, terminal 83 transmits CW and / or commands to tag 82, and tag 82, upon receiving the CW and / or commands, directly transmits feedback information to network-side device 81. The first resource is the UL resource of the CW and / or commands transmitted by terminal 83 to tag 82 (the configuration information of this resource is sent to terminal 83 by network-side device 81), and the second resource is used to transmit the feedback information from tag 82.

[0156] Optionally, in the embodiments of this application, in Figure 8 In the application scenario shown, if both the first and second resources configured on network-side device 81 are semi-static resources, then as follows: Figure 9 As shown, each UL resource corresponds to one BSC resource, or multiple UL resources correspond to one BSC resource. That is, after terminal 83 transmits CW and / or commands multiple times, multiple tags will transmit their feedback information to network-side device 81. Both the first and second resources are periodic. Terminal 83 transmits CW and / or commands to tag 82 on the UL resource, and tag 82 transmits feedback information to network-side device 81 on the BSC channel. The configuration information of the UL resource is provided to terminal 83 by network-side device 81.

[0157] Optionally, in the embodiments of this application, in Figure 8 In the application scenario shown, if both the first and second resources configured by the network-side device 81 are dynamic resources, then the network-side device 81 dynamically schedules the DL and UL resources through DCI. Specifically, the network-side device 81 can use dynamic DCI to instruct the terminal 83 on relevant configuration information regarding the UL resources; the time interval between the terminal 83 transmitting CWs and commands is greater than or equal to a specific time interval T1; the duration of the CW is fixed or variable, and further, the duration of the CW can be related to the command type; the first control command is used to indicate the command type transmitted by the network-side device 81 to the tag 82. The terminal 83 can transmit CWs and / or commands to the tag 82 on the UL resources. After receiving the CW and / or command, the tag 82 can transmit corresponding feedback information to the network-side device 81 according to different control command types.

[0158] It can be seen that in the above Figure 6 and Figure 8 In both application scenarios shown, the terminal participates in the backscatter communication process. Through the participation of the terminal, the range of backscatter communication can be expanded on the one hand, and the communication of the backscatter communication system supported by 5G NR can be realized on the other hand.
