The resource allocation method, the device, the communication equipment, the system and the storage medium provided by the embodiment of the application are described in detail below through some embodiments and application scenes thereof with reference to the accompanying drawings.

Backscatter communication refers to the transmission of its own information by signal modulation of radio frequency signals in other devices or environments by a backscatter communication device. Wherein the backscatter communication device may be any one of the following a to c:

a. the backscatter communication device in conventional radio frequency identification (Radio Frequency Identification, RFID), typically a tag, belongs to a Passive internet of things (Passive Internet of Things, passive-IoT) device;

b. semi-passive (i.e. semi-passive) tags, and the downlink receiving or uplink reflection of the type of tags has a certain amplifying capability;

c. the tag with active sending capability (i.e. active tag) can send information to reader without depending on reflection of incident signals.

The method of signal transmission between reader and tag in backscatter communications is exemplarily described below with reference to the accompanying drawings.

For example, assuming that when the tag needs to transmit '1', the tag reflects the incident signal, and when the tag needs to transmit '0', the tag22 does not reflect the incident signal, as shown in fig. 2, after receiving the incident signal 23 transmitted by the reader21, the tag22 may change the amplitude, frequency, phase, etc. of the incident signal 23 by adjusting the impedance inside the tag22, so as to implement modulation of the signal, and reflect the modulated incident signal 24 to the reader21, so as to transmit information of the tag 22.

Specifically, the reflected signal S _out (t) and the incident signal S _in The relationship between (t) can be expressed by the following formula (1):

where Γ is the reflection coefficient of the circuit in tag, and the reflection coefficient Γ may be characterized by the following equation (2):

wherein Z is ₀ For the characteristic impedance of the antenna, Z ₁ Is the load impedance.

It can be seen that the tag can control the reflection coefficient Γ of the circuit in the tag by adjusting the internal impedance, thereby implementing amplitude modulation, frequency modulation or phase modulation of the incident signal.

FIG. 3 is a schematic diagram showing information transmission between a reader and a tag, and as shown in FIG. 3, in the process of information transmission between the reader and the tag, the workflow of the reader includes: selecting, checking and accessing. Wherein, selecting a process of selecting a tag group for a subsequent inventory or a cryptographic challenge tag group for a subsequent verification for the reader, and selecting a command comprising a selection command and a challenge command; counting is a process of identifying tags by a reader, wherein the reader starts a counting process by transmitting a query command in one of four sessions, one or more tags can reply, the reader detects a single tag reply, the counting process is executed in one session and only one session, and the counting process comprises a plurality of commands; access is the process of a reader transacting (reading, writing, authenticating or otherwise participating) with a single tag, the reader individually and uniquely identifying the tag prior to access, and the access includes multiple commands.

In the process of information transmission between the reader and the tag, the instruction of the operation of the reader is as follows in tables 1 and 2:

TABLE 1

TABLE 2

As shown in fig. 3, in the process of information transmission between a reader and a tag, the states of the tag include: ready, mediation, response, reply, turn on, protection, and destruction. A specific description of the respective states of tags is shown in table 3 below:

TABLE 3 Table 3

Currently, in the checking mode, the protocol design of the ultra-high frequency (Ultra High Frequency, UHF) RFID requires that the reader respond and generate a 16-bit random number to the reader after sending a Query command (i.e., query), and then the reader sends the sequence to the tag through an ACK command, and the tag sends related data to the reader. In existing backscatter communication systems, a reader typically receives only one tag of backscatter signal 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, tag generates a {0, …,2 locally ^Q And (3) randomly selecting one value q from the values of-1, wherein the tag with the current random value 0 responds to a reader control command to transmit a back scattering signal, and the tag with the current random value not being 0 does not transmit the back scattering signal. After completing communication with a tag having a random value of 0, the Reader may continue to transmit control commands (e.g., queryRep), for example, instructing the tag to subtract 1 from the generated random value, and the tag having a random value of 0 to perform backscatter transmission in response to the control commands.

The above procedure belongs to a random multiple access procedure, and because there is a possibility that multiple tags locally generate the same random number, multiple tags can perform backscatter transmission at the same time, in this case, the reader cannot detect any backscatter signal with high probability, and no feedback is given to the backscatter signal received by the tags, so that the tags can continue to receive the control command of the reader, and wait for a new opportunity of backscatter transmission. Therefore, when the reader sends the control command, a reasonable Q value should be selected, and the Q value should be gradually adjusted during the checking process, so as to reduce the collision probability in the communication process with multiple tags, which, however, means that the time for completing the communication with multiple tags will be longer.

The existing backscatter communication system supports communication between a reader and a tag, and the tag can receive an incident signal sent by the reader within the coverage area of the incident signal, so that the modulated incident signal can be reflected to the reader, thus the range of backscatter communication is smaller. And because a new terminal is introduced into a back-scattering communication system supported by 5G NR in the future, reasonable allocation of uplink and downlink resources among a reader, a terminal and a tag is a problem to be solved.

In order to solve the above-mentioned problems, the embodiments of the present application provide a resource allocation method, where a terminal may receive configuration information from a reader; the configuration information is used for configuring resources related to transmission of at least one tag. By the scheme, the terminal can transmit CW and/or command to at least one tag according to the configuration information received from the reader, or receive feedback information transmitted by at least one tag, so that the terminal can participate in the transmission related to the tag, and the range of the backscatter communication can be enlarged due to the increased participation of the terminal in the backscatter communication. Further, communication of the backscatter communication system in which the terminal supported by 5G NR participates can also be implemented.

For example, the period of the second resource is 1 time the period of the first resource, i.e. the period of the second resource is equal to the period of the first resource.

In the embodiment of the present application, since the association of the first resource with the second resource may include at least one of (2.1) and (2.2) described above, flexibility of the association of the first resource with the second resource may be improved.

In this embodiment of the present application, since the first resource is related to the second resource, that is, the resource for transmitting the CW and/or the command to each of the above-mentioned backscatter communication devices is related to the resource for transmitting the feedback information of each of the backscatter communication devices, collision of transmission resources may be reduced, and thus the success rate of transmission may be improved.

Alternatively, in the embodiment of the present application, after the network side device receives the feedback information of the backscatter communication device, the backscatter communication may be completed.

For other descriptions in the embodiments of the present application, reference may be specifically made to the related descriptions in the terminal-side embodiments, and in order to avoid repetition, a detailed description is omitted here.

In the resource allocation method provided by the embodiment of the present application, the network side device may send configuration information for configuring resources related to transmission of at least one backscatter communication device to the terminal, and may transmit CW and/or a command to the at least one backscatter communication device according to the configuration information, or receive feedback information transmitted by the at least one backscatter device, so that the network side device may instruct the terminal to participate in transmission related to the backscatter communication device, and may expand a range of backscatter communication due to participation of the terminal in conventional backscatter communication.

The resource allocation method provided in the embodiment of the present application is described in detail below with reference to the accompanying drawings, taking a backscatter device as an example.

Fig. 6 shows a scenario where the resource allocation method provided in the embodiment of the present application is applied, as shown in fig. 6, where the network side device 61 transmits a CW and/or a command to the tag 62, the tag 62 transmits feedback information to the terminal 63 after receiving the CW and/or the command, and the terminal 63 transmits the received feedback information of the tag 62 to the network side device 61. The first resource is a Downlink (DL) resource of a CW and/or a command transmitted to the tag 62 by the network side device 61, and the second resource is an Uplink (UL) resource for transmitting feedback information of the tag 62.

Optionally, in the embodiment of the present application, in the application scenario shown in fig. 6, if the first resource and the second resource configured by the network side device 61 are semi-static resources, as shown in fig. 7, each DL resource corresponds to one UL resource, or a plurality of DL resources correspond to one UL resource, that is, after receiving feedback information of a plurality of tags, the terminal 63 transmits all the feedback information to the network side device 61 together. Wherein, DL resources and UL resources are both periodic (i.e., period), and K1 is a time interval between an end time of the first resource and a start time of the second resource. After the network side device 61 transmits the CW and/or the command to the tag 62 through the first resource, the tag 62 may charge and perform the backscatter communication through the CW, the terminal 63 receives feedback information of the tag on a backscatter communication (Backscatter Communication, BSC) channel, and transmits the received feedback information to the network side device 61 with or without integration using the UL resource after the K1 time has elapsed.

Optionally, in the embodiment of the present application, in the application scenario shown in fig. 6, if the first resource and the second resource configured by the network side device 61 are dynamic resources, the network side device 61 may dynamically schedule DL resources and UL resources through DCI. Wherein the time interval during which the network side device 61 transmits the CW and the command is greater than or equal to the specific time interval T1, the duration of the CW is fixed or variable, and the first control command may be used to instruct the terminal 63 to report the start time of UL resources of the backscatter content to the network side device 61, or to instruct the network side device 61 to issue a command type of the command to the tag 62. The network side device 61 may instruct the terminal 63 to transmit the feedback information of the received tag 62 on the corresponding UL resource location through DCI. If the terminal 63 receives the first control command, the terminal 63 may know the feedback information of the expected tag 62, and determine whether to integrate and send the feedback information received subsequently. In case the terminal 63 receives the first control command, the terminal 63 does not need an additional indication; in case the terminal 63 knows the first control command type through DCI indication, the terminal 63 needs an additional indication. If the terminal 63 does not receive the first control command, the terminal 63 cannot predict the feedback information of the tag 62, so that the terminal 63 can directly transmit the feedback information to the network side device 61 on the available UL resource after receiving the feedback information of the tag 62 in a transparent transmission manner.

Fig. 8 illustrates another scenario of application of the resource allocation method provided in the embodiment of the present application, as shown in fig. 8, the terminal 83 transmits a CW and/or a command to the tag 82, and the tag 82 directly transmits feedback information to the network side device 81 after receiving the CW and/or the command. The first resource is a CW and/or a UL resource of a command transmitted to the tag 82 by the terminal 83 (configuration information of the resource is transmitted to the terminal 83 by the network side device 81), and the second resource is feedback information for transmitting the tag 82.

Optionally, in the embodiment of the present application, in the application scenario shown in fig. 8, if the first resource and the second resource configured by the network side device 81 are semi-static resources, as shown in fig. 9, each UL resource corresponds to one BSC resource, or a plurality of UL resources corresponds to one BSC resource, that is, after the terminal 83 transmits the CW and/or the command multiple times, a plurality of labels transmit the feedback information given to the network side device 81. Wherein, the first resource and the second resource are both periodic, the terminal 83 transmits CW and/or command to the tag 82 on UL resource, the tag 82 transmits feedback information to the network side device 81 on BSC channel, wherein the network side device 81 informs the terminal 83 of the configuration information of UL resource.

Optionally, in the embodiment of the present application, in an application scenario shown in fig. 8, if the first resource and the second resource configured by the network side device 81 are both dynamic resources, the network side device 81 dynamically schedules DL resources and UL resources through DCI. Wherein, the network side device 81 may instruct the terminal 83 about relevant configuration information of UL resources through dynamic DCI; the time interval at which the terminal 83 transmits CW and the command is greater than or equal to a specific time interval T1; the CW is fixed or variable in duration, and further, the length of the duration of the CW may be related to the command type; the first control command is used to indicate the type of command that the network side device 81 transmits to the tag 82. Terminal 83 may transmit CW and/or commands on UL resources to tag 82, and tag 82 may transmit corresponding feedback information to network-side device 81 according to different control command types after receiving the CW and/or commands.

It can be seen that in the two application scenarios shown in fig. 6 and fig. 8, the terminal participates in the process of backscatter communication, and by participation of the terminal, on one hand, the range of backscatter communication can be enlarged, and on the other hand, communication of a backscatter communication system supported by 5G NR can be realized.
