[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to Chinese patent application No. 202311136513.0 filed in China on September 4, 2023, the entire contents of which are incorporated herein by reference. Technical Field

[0003] The present application belongs to the field of communication technology, and specifically relates to a transmission method, device, answering device and reading and writing device. Background Art

[0004] At present, the interaction between the reader and the answering device of the Radio Frequency Identification (RFID) is based on the inventory mode. For example, the communication between the reader and the tag is based on the inventory mode. Specifically, in an inventory, the reader sends a query instruction. After receiving the query instruction, the answering device generates a random number A. When the random value A is zero, the answering device responds to the query instruction of the reader and generates a 16-bit random value, namely RN16, and sends it to the reader. After receiving the RN16, the reader verifies the RN16 to confirm whether the answering device has correctly responded to the query instruction of the reader. If the reader determines that the answering device has correctly responded to the query instruction, it sends an acknowledgment (ACK) instruction to the answering device, and then the answering device can send the relevant data to the reader. It can be seen that the above inventory method only supports the reader to inventory one answering device at a time, and has low flexibility.

[0059] For ease of understanding, some of the contents involved in the embodiments of this application are described below:

[0060] 1. Backscatter Communication (BSC)

[0061] Backscatter communication refers to the backscatter communication device using the radio frequency signals from other devices or the environment to modulate the signal to transmit its own information. For example, as shown in Figure 2, the reader sends a continuous carrier to the tag to transmit control commands, and the tag transmits information to the reader by backscattering the radio frequency signal sent by the reader.

[0062] Exemplarily, the backscatter communication device may include the following devices:

[0063] Device A: A backscatter communication device in traditional RFID, typically a tag, which is a passive IoT device.

[0064] Device B: A semi-passive IoT device that has a certain amplification capability for downlink reception or uplink reflection.

[0065] Device C: An active device capable of sending signals. This type of transponder can generate signals autonomously and does not require an external excitation signal source.

[0066] The energy source of the above-mentioned backscatter communication device can come from the environment, for example, ambient radio frequency (RF) signals, thermal energy, kinetic energy, wind energy, etc. Therefore, the above-mentioned backscatter communication device can also be called an ambient IoT device.

[0067] For a transmission method based on backscattering, a simple implementation method is that when the tag needs to send a '1', the tag reflects the incident carrier signal, and when the tag needs to send a '0', it does not reflect.

[0068] Backscatter communication equipment controls the circuit's reflection coefficient Γ by adjusting its internal impedance, thereby changing the amplitude, frequency, phase, etc. of the incident signal to achieve signal modulation. The signal reflection coefficient can be expressed as:

[0069] Γ=(Z_1-Z_0) / (Z_1+Z_0)=|Γ|e^(jθ_T)

[0070] Where Z_0 is the antenna characteristic impedance, and Z_1 is the load impedance. Assuming the incident signal is S_in(t), the output signal is S_out(t) = S_in(t)|Γ|e^(jθ_T). Therefore, by properly controlling the reflection coefficient, corresponding amplitude modulation, frequency modulation, or phase modulation can be achieved.

[0071] 2. Information Transmission between Reader and Tag in RFID

[0072] The instructions for the above Reader operation may be shown in Table 1.

[0073] Table 1

[0074] The status of the above tag can be shown in Table 2.

[0075] Table 2

[0076] For example, the transmission and reception process between the reader and the tag can be shown in Figure 3. The current Ultra High Frequency (EHF) RFID protocol design, in inventory mode, requires the reader to send a query command (Query), and the tag to respond (Reply), generating a 16-bit random number (RN16) to the reader. The reader then sends an ACK command back to the tag, and the tag sends the relevant data to the reader, such as the control protocol (PC) / extended protocol control (XPC), the electronic product code (EPC), and the packet cyclic redundancy check (CRC).

[0077] 3. Reader Inventory Tags

[0078] In the inventory process of related readers and tags, a reader can only inventory one tag in one inventory. If multiple tags are counted by the reader at the same time, the conflict resolution mechanism will be executed and the inventory process will be restarted until there are no conflicts. At this time, the inventory efficiency is low.

[0079] The transmission method provided in the embodiments of the present application is described in detail below through some embodiments and their application scenarios in combination with the accompanying drawings.

[0080] Please refer to Figure 4, which is a flowchart of a transmission method provided in an embodiment of the present application. The method can be executed by a response device. The response device can refer to the above-mentioned relevant description of the response device 11, which is not repeated here.

[0081] As shown in FIG4 , the transmission method provided in the embodiment of the present application includes the following steps:

[0082] Step 401: The answering device determines a first quantity, wherein the first quantity is the quantity of resource objects available to the answering device, and the resource objects include resources or resource groups.

[0083] In this embodiment, the first number is the number of resources available to the answering device or the number of available resource groups. For example, the first number may be the number of frequency resources available to the answering device or the number of available frequency resource groups. The resource groups may also be referred to as resource blocks.

[0084] Exemplarily, the first quantity may be configured or preconfigured by the network side device, or may be indicated by the read / write device, or may be determined by the response device according to the number of resource objects carrying the control commands sent by the read / write device.

[0085] It should be noted that the first number may be greater than or equal to 1. In addition, in some optional embodiments, the first number may be understood as the number of resource objects available for parallel transmission by the answering device based on frequency division multiplexing (FDM).

[0086] Step 402: The answering device performs a first operation, where the first operation includes at least one of the following:

[0087] determining whether to transmit information to a read / write device based on the first number and a first random number generated by the answering device;

[0088] A transmission resource is determined from the available resource objects according to the first number and a first random number generated by the response device.

[0089] In this embodiment, the above-mentioned first random number can be a random number within a first numerical range, wherein the first numerical range can be agreed upon by the protocol, or can be configured or pre-configured by the network side device, or can be determined according to the counting parameters indicated by the read-write device.

[0090] In some optional embodiments, the value range of the first random number is [0,2 Q -1], wherein Q is a counting parameter received by the answering device from the reading and writing device, and Q is an integer greater than or equal to 1.

[0091] The above-mentioned response device determines whether to transmit information to the read-write device based on the first number and the first random number generated by the response device. Exemplarily, the response device can determine to transmit information to the read-write device if the first random number meets a preset condition, that is, the response device responds to the read-write device. The above-mentioned preset condition can include that the first random number is within the second numerical range, or the first random number is less than or equal to the first number. The above-mentioned second numerical range includes N integers in the first numerical range, where N represents the first number. For example, if the above-mentioned first numerical range is [0,15] and N is 3, then the above-mentioned second numerical range can include 3 integers in [0,15]. For example, the above-mentioned second numerical range can include 0, 1, and 2, or the above-mentioned second numerical range can include 1, 2, and 3, or the above-mentioned second numerical range can include 13, 14, and 15.

[0092] The response device determines a transmission resource from the available resource objects based on the first number and a first random number generated by the response device. For example, when the first random number is within a second numerical range, the response device determines a resource object from N resource objects based on the first random number as the transmission resource, where N represents the first number.

[0093] The present embodiment is described below with reference to examples:

[0094] When the answering device receives a query instruction or the like sent by the read / write device, it can determine the number of available resource objects, i.e., a first number, and generate a first random number. When the first random number satisfies a preset condition, for example, the first random number is less than the first number, the answering device determines a transmission resource from N available resource objects based on the first random number and sends an RN16 to the read / write device. When the answering device receives an ACK instruction sent by the read / write device, the answering device transmits data to the read / write device based on the determined transmission resource. The RN16 is a 16-bit random number.

[0095] In the transmission method provided by the embodiment of the present application, the answering device determines a first quantity, wherein the first quantity is the number of resource objects available to the answering device, and the resource objects include resources or resource groups; the answering device performs a first operation, and the first operation includes at least one of the following: determining whether to transmit information to the read-write device based on the first quantity and a first random number generated by the answering device; determining a transmission resource from the available resource objects based on the first quantity and the first random number generated by the answering device, that is, in the embodiment of the present application, the answering device determines whether to respond to the read-write device and determines at least one of the transmission resources for transmitting information to the read-write device based on the number of available resource objects and the random number generated by it. In this way, the number of answering devices that can be inventoried by the read-write device in one inventory can be flexibly adjusted according to the number of resource objects available to the answering device, thereby improving the flexibility of the read-write device in inventorying the answering devices.

[0096] Optionally, the answering device determines whether to transmit information to the read-write device according to the first number and a first random number generated by the answering device, including:

[0097] The response device determines to transmit information to the read-write device when the first random number is smaller than the first quantity.

[0098] In this embodiment, when the first random number is less than the first quantity, information is transmitted to the read / write device, that is, the response device responds to the read / write device. The above-mentioned information transmission to the read / write device may include transmitting RN16, EPC, packet CRC, etc. to the read / write device.

[0099] It can be understood that since the random number generated in this embodiment is less than the first number, all answering devices can respond to the read-write device. In this way, when the first number is greater than 1, more than one answering device can respond to the read-write device in one inventory, which can improve the efficiency of the read-write device in taking inventory of the answering devices.

[0100] Optionally, the method further includes:

[0101] When the first random number is greater than or equal to the first quantity, the response device determines to at least one of not transmit information to the read / write device and wait for a random number decrement instruction.

[0102] In this embodiment, the above-mentioned random number decrement instruction is used to instruct the answering device to decrement the generated random number. For example, if the current value of the first random number is M, the answering device uses MK as the value of the first random number after the random number is decremented when receiving the random number decrement instruction, where K is the random number decrement step.

[0103] In one embodiment, the above-mentioned response device determines not to transmit information to the read-write device when the first random number is greater than or equal to the first number. For example, the response device determines not to transmit information to the read-write device in the current inventory when the first random number is greater than or equal to the first number, that is, the response device does not respond to the read-write device, and in the next inventory, the response device can regenerate a random number and compare it with the first number; or, the response device does not transmit information to the read-write device in the current polling of the current inventory, that is, the response device does not respond to the read-write device, and when the response device receives a random number decrement instruction, it can decrement the generated random number based on the random number decrement instruction and compare the decremented random number with the first number. If the decremented random number is less than the first number, the response device can respond to the read-write device.

[0104] In another embodiment, the above-mentioned response device waits for a random number decrement instruction when the first random number is greater than or equal to the first number, and can, when receiving the random number decrement instruction, decrement the generated random number (i.e., the first random number) based on the random number decrement instruction, and compare the decremented random number with the first number. If the decremented random number is less than the first number, the response device can respond to the read-write device.

[0105] In another embodiment, when the first random number is greater than or equal to the first quantity, the above-mentioned answering device determines not to transmit information to the read-write device, that is, not to respond to the read-write device, and waits for the random number decrement instruction. When the random number decrement instruction is received, the answering device can decrement the generated random number (that is, the first random number) based on the random number decrement instruction, and compare the decremented random number with the first quantity. If the decremented random number is less than the first quantity, the answering device can respond to the read-write device.

[0106] Since each answering device in this embodiment determines to transmit information to the read-write device when the generated random number is less than the first number, and otherwise determines not to transmit information to the read-write device and waits for at least one of the random number decrement instructions, this facilitates controlling the number of answering devices that respond to the read-write device simultaneously and reduces conflicts between answering devices.

[0107] In some optional embodiments, when there are at least two answering devices that generate the same random number and are less than the first number, a conflict avoidance mechanism may be executed. For example, the read-write device may instruct the at least two answering devices that have conflicted to remain silent in the current inventory or no longer respond to the read-write device in the current inventory. For example, when multiple answering devices respond to the read-write device in an inventory, each sends an RN16 random number, the read-write device receives the RN16 sent by the multiple answering devices, and may feed back ACK and the received RN16 to the answering device. When the multiple answering devices receive the ACK and RN16 fed back by the read-write device, the multiple answering devices will The received RN16 is compared with the RN16 generated by it respectively. When the RN16 received by a certain answering device does not include the RN16 generated by it, it is determined that a conflict has been sent. In this case, the answering device where the conflict occurs remains silent in the current inventory or no longer responds to the read-write device in the current inventory. For example, the answering device no longer participates in the subsequent random number decrement process of the current inventory; or, the read-write device can re-initiate the inventory process, that is, trigger all answering devices to regenerate random numbers and compare them with the first number; or, the read-write device can instruct the at least two answering devices where the conflict occurs to wait for different lengths of time before transmitting.

[0108] Optionally, the response device determines the transmission resource from the available resource objects according to the first number and a first random number generated by the response device, including:

[0109] The response device determines the resource object corresponding to the first random number among the N resource objects as the transmission resource;

[0110] Here, N is the first number, and the N resource objects are resource objects available to the response device.

[0111] In this embodiment, the correspondence between N resource objects and N random numbers can be pre-defined. For example, the larger the random number, the higher the frequency domain mapping position of the corresponding resource object, or the larger the random number, the lower the frequency domain mapping position of the corresponding resource object. In this way, each response device can determine the resource object corresponding to the random number generated by it among the above-mentioned N resource objects based on the random number it generates and the above-mentioned correspondence, and use it as the transmission resource of the response device. This can save indication signaling overhead while reducing the occurrence of resource transmission conflicts between response devices.

[0112] Optionally, the center frequency point of the resource object may be used as a representation of the frequency domain mapping position of the resource object. For example, the larger the frequency corresponding to the center frequency point of the resource object, the higher the frequency domain mapping position of the resource object.

[0113] Optionally, the random number with a value of i corresponds to the i+1th resource object among the N resource objects, or the random number with a value of i corresponds to the Nith resource object among the N resource objects, where i is an integer greater than or equal to 0 and less than N.

[0114] In this embodiment, the above-mentioned N resource objects can be arranged from high to bottom according to the frequency domain mapping position, or can be arranged from low to high according to the frequency domain mapping position, wherein the larger the random number, the higher the frequency domain mapping position of the corresponding resource object, or the larger the random number, the lower the frequency domain mapping position of the corresponding resource object.

[0115] For example, when N is 4, the random number with a value of 0 corresponds to the first resource object, the random number with a value of 1 corresponds to the second resource object, the random number with a value of 2 corresponds to the third resource object, and the random number with a value of 3 corresponds to the fourth resource object; or, the random number with a value of 0 corresponds to the fourth resource object, the random number with a value of 1 corresponds to the third resource object, the random number with a value of 2 corresponds to the second resource object, and the random number with a value of 3 corresponds to the first resource object.

[0116] For another example, when N is 4, there are four frequency positions that can be mapped. If the random number generated by the answering device is 2, it can be mapped to the second frequency position from top to bottom, or it can be mapped to the second frequency position from bottom to top; if the random number generated by the answering device is 0, it can be mapped to the first frequency position from top to bottom, or it can be mapped to the first frequency position from bottom to top.

[0117] In this embodiment, by making a random number with a value of i correspond to the i+1th resource object among the N resource objects, or making a random number with a value of i correspond to the Nith resource object among the N resource objects, the complexity of resource mapping can be reduced.

[0118] Optionally, the starting position of the available resource object is predefined by a protocol or preconfigured by a network-side device.

[0119] Exemplarily, in the case where the resource object is a frequency domain resource or a frequency domain resource group, the frequency domain starting position of the frequency domain resource or the frequency domain resource group may be predefined by a protocol or preconfigured by a network-side device.

[0120] In some optional embodiments, the network side device can pre-configure the starting position of the available frequency domain resource group, the working bandwidth of the response device, and the size of each frequency domain resource group, so that the response device can determine the number of frequency domain resource groups, the frequency domain position of each frequency domain resource group and other information based on the above pre-configuration.

[0121] Optionally, the method further includes:

[0122] The answering device determines a target step length according to the first number, where the target step length is a step length used by the answering device to modify a random number.

[0123] For example, when the target step size is the step size for the answering device to decrement the random number, the target step size may also be referred to as the random number decrement step size. Specifically, when the answering device receives the random number decrement instruction sent by the read-write device, it may decrement the random number based on the target step size.

[0124] Optionally, the target step size is less than or equal to the first number.

[0125] For example, when there are 10 answering devices that receive a query instruction sent by a read-write device, and the random numbers generated by the 10 answering devices are 0-9, if the number of available resource objects is 5, then in the first round of inventory, only the answering devices that generate random numbers from 0 to 4 can transmit information uplink, and the answering devices that generate random numbers from 5 to 9 execute a waiting mechanism. If the step size of the random number modification is 5, then in the second round of inventory, the answering devices that generate random numbers from 5 to 9 will update the random numbers to 0 to 4 respectively. In this case, these 5 answering devices can all transmit information uplink.

[0126] Optionally, the method further includes:

[0127] The answering device receives a control instruction from the reading and writing device;

[0128] The control instruction carries the first quantity, or the first quantity is determined according to a second quantity, and the second quantity is the quantity of resource objects carrying the control instruction.

[0129] In this embodiment, the control instructions may include but are not limited to query (Query) instructions, query adjustment (Query Adjust) or repeated query (QueryRep) and the like.

[0130] In one embodiment, the read / write device may explicitly indicate the first quantity to the answering device, that is, carry the first quantity in the control instruction, so that the answering device can accurately and quickly know the quantity of available resource objects.

[0131] In another embodiment, the first number may be determined based on the number of resource objects carrying the control instructions, which can reduce changes to existing control instructions of the read-write device.

[0132] For example, a calculation formula for calculating the first quantity based on the second quantity can be agreed in advance, for example, the first quantity is equal to the second quantity + L, or the first quantity is equal to the rounded value of the second quantity / Y, etc., where L is an integer and Y is a positive number. In this way, the first quantity can be quickly determined based on the above second quantity and the calculation formula.

[0133] It should also be noted that the read-write device sends control commands on the downlink frequency resources, and the size of the downlink frequency resources can be configured / pre-configured by the network side device. In addition, the number of downlink resource groups, the size of each resource group, and the frequency domain position of each resource group are all configurable. For example, as shown in Figure 5a, the control command can be carried on a resource group A. In order to facilitate the description of the position of resource group A in the frequency domain, a frequency reference point can be set. The frequency reference point can be a carrier frequency for the read-write device to send an excitation carrier signal, or it can be a virtual reference frequency point. If there are more frequency resources available to the read-write device at this time, the control command can be carried on multiple resource groups, as shown in Figure 5b or Figure 5c. For example, as shown in Figure 5c, it is carried on 4 resource groups.

[0134] Optionally, the first quantity is equal to the second quantity.

[0135] In this embodiment, the first number is equal to the second number, so that the number of resource objects available to the answering device can be conveniently determined based on the number of resource objects carrying the control instructions.

[0136] In some optional embodiments, the first number may be greater than the second number, or the first number may be less than the second number.

[0137] The following examples illustrate this embodiment:

[0138] Case 1: The first quantity is equal to the second quantity.

[0139] If the bandwidth of the resource object carrying the control command is 10 MHz and the bandwidth of each resource object is 2 MHz, there are 5 resource objects, i.e., the second number is 5. If the bandwidth available to the answering device is 10 MHz and the bandwidth of each resource object is 2 MHz, the first number is also 5. In this case, the first number is equal to the second number.

[0140] Case 2: The first quantity is greater than the second quantity.

[0141] If the bandwidth of the resource objects carrying the control command is 10 MHz and the bandwidth of each resource object is 2 MHz, there are 5 resource objects, i.e., the second number is 5. If the bandwidth available to the answering device is 10 MHz and the bandwidth of each resource object is 1 MHz, then the first number is 10. In this case, the first number is greater than the second number.

[0142] Case 3: The first quantity is smaller than the second quantity.

[0143] If the bandwidth of the resource object carrying the control command is 10 MHz and the bandwidth of each resource object is 2 MHz, there are 5 resource objects, i.e., the second number is 5. If the bandwidth available to the answering device is 5 MHz and the bandwidth of each resource object is 2.5 MHz, then the first number is 2. In this case, the first number is smaller than the second number.

[0144] Optionally, the second number is configured or preconfigured by a network-side device;

[0145] Alternatively, the second number is carried by the control instruction;

[0146] Alternatively, the second number is obtained by the response device detecting a resource object carrying the control instruction;

[0147] Alternatively, the second number is determined by a sequence mapped on a preset position of the resource object carrying the control instruction, wherein different sequences correspond to different numbers of resource objects.

[0148] The second number is obtained by the answering device detecting the resource object carrying the control instruction. For example, the answering device may detect the resource object carrying the control instruction at multiple detection points, wherein the multiple detection points are pre-configured or pre-indicated. The following describes the answering device detecting the resource object carrying the control instruction with reference to an example:

[0149] Case 1: When the control command is carried on a resource group, that is, the read-write device sends the control command on a resource group, as shown in Figure 6a, the response device performs resource group detection at multiple detection points and successfully detects the control command at detection point 1, as shown in Figure 6b. At this time, the response device determines that the number of resource groups sent by the read-write device is one, that is, the second number is 1.

[0150] In this case, if the control command also carries a counting parameter Q, the answering device generates a [0,2 Q-1]. For example, when Q is 4, the answering device generates a random number between [0, 15]. Since the second number is 1, only the answering device that generates a random number of 0 can respond to the signal sent by the read / write device. As shown in Figure 6c, the random number generated by the counter of answering device 1 is 0, the random number generated by the counter of answering device 2 is 3, and the random number generated by the counter of answering device 3 is 6. In this case, answering device 1 can respond to the signal sent by the read / write device, while answering devices 2 and 3 will not respond for the time being, executing the waiting mechanism.

[0151] Case 2: When the control command sent by the read-write device is carried on 4 resource groups, that is, the read-write device sends the control command on 4 resource groups, as shown in Figure 7a, the response device performs resource group detection at multiple detection points, as shown in Figure 7b. At this time, the response device determines that the number of resource groups sent by the read-write device is 4, that is, the second number is 4.

[0152] In this case, if the control command also carries a counting parameter Q, the answering device generates a [0,2 Q -1]. For example, when Q is equal to 4, the answering device generates a random number between [0, 15]. Since the second number is 4, the answering devices that generate random numbers from 0 to 3 can respond to the signal sent by the read-write device. As shown in Figure 7c, the random number generated by the counter of answering device-1 is 0, the random number generated by the counter of answering device-2 is 1, the random number generated by the counter of answering device-3 is 4, the random number generated by the counter of answering device-4 is 2, and the random number generated by the counter of answering device-5 is 3. Therefore, answering device-1, answering device-2, answering device-4, and answering device-5 can respond to the read-write device, while answering device-3 does not respond for the time being and executes the waiting mechanism.

[0153] The second number is determined by a sequence mapped at a preset position of the resource object carrying the control instruction, wherein different sequences correspond to different numbers of resource objects. For example, a sequence indicating the second number can be mapped at the start position or end position of each resource object carrying the control instruction, so that when each response device detects the sequence on any resource object carrying the control instruction, the second number can be determined based on the sequence. For example, if a read / write device maps control signaling on S resource groups, and the response device detects the sequence indicating the second number on T resource groups out of the S resource groups, where T is greater than or equal to 1 and less than or equal to S, the number of resource groups carrying the control instruction can be determined based on the detected sequence, thereby reducing the complexity of the response device in detecting the number of resource objects.

[0154] Please refer to Figure 8, which is a flowchart of a transmission method provided in an embodiment of the present application. The method can be executed by a read-write device. The read-write device can refer to the relevant description of the aforementioned read-write device 12 and will not be repeated here.

[0155] As shown in FIG8 , the transmission method provided in the embodiment of the present application includes the following steps:

[0156] Step 801: The read / write device determines a first quantity, where the first quantity is the quantity of resource objects available to the response device, and the resource objects include resources or resource groups.

[0157] Exemplarily, the read-write device can determine the first quantity based on the number of resource objects available to the response device indicated by the network side device, or the read-write device can determine the number of resource objects available to the response device based on the resource configuration information or resource pre-configuration information of the response device. For example, the network side device can configure or pre-configure the working bandwidth of the response device and the size of each frequency domain resource group, so that the response device can determine the number of resource groups available to the response device based on the working bandwidth of the response device and the size of each frequency domain resource group; or the read-write device can determine the number of resource objects available to the response device based on the number of resource objects available to the read-write device.

[0158] Step 802: The reader / writer device indicates at least one of the first number and a target step length to the answering device, wherein the target step length is a step length used by the answering device to modify a random number, and the target step length is determined based on the first number.

[0159] In one embodiment, the read / write device indicates the first quantity to the answering device. Exemplarily, the read / write device may explicitly send the first quantity to the answering device, or the read / write device may implicitly indicate the first quantity to the answering device. For example, the read / write device indicates the first quantity to the answering device by carrying the number of resource objects controlled.

[0160] For example, upon receiving the first number indicated by the reader / writer device, the answering device may determine whether to respond to the reader / writer device based on the first number and a random number generated by the answering device. For example, if the generated random number is less than the first number, the answering device may respond to the reader / writer device; otherwise, the answering device may not respond to the reader / writer device and a waiting mechanism may be implemented.

[0161] In another embodiment, the reader / writer device indicates a target step size to the answering device, where the target step size is determined based on the first number. For example, the target step size may be equal to the first number. For example, the reader / writer device may explicitly send the target step size to the answering device, or the reader / writer device may implicitly indicate the target step size to the answering device, for example, by indicating the target step size to the answering device via the number of resource objects controlled by the bearer.

[0162] For example, if the answering device obtains the target step size indicated by the read / write device and receives a random number decrement instruction from the read / write device, it can subtract the target step size from the generated random number and determine whether to respond to the read / write device based on the modified random number and the first number. It is understood that in this case, the first number can be determined by the answering device itself, rather than indicated by the read / write device.

[0163] In another embodiment, the read / write device indicates the first quantity and the target step size to the answering device. For example, the read / write device may explicitly send the first quantity and the target step size to the answering device, or the read / write device may implicitly indicate the first quantity to the answering device, for example, by indicating the first quantity and the target step size to the answering device via the number of resource objects controlled by the bearer.

[0164] For example, upon receiving the first number and target step size indicated by the reader / writer device, the answering device may determine whether to respond to the reader / writer device based on the first number and a random number generated by the answering device. For example, if the generated random number is less than the first number, the answering device may respond to the reader / writer device; otherwise, the answering device may not respond to the reader / writer device and execute a waiting mechanism. If the answering device receives a random number decrement instruction from the reader / writer device, the answering device may subtract the target step size from the generated random number and determine whether to respond to the reader / writer device based on the modified random number and the first number.

[0165] In the transmission method provided by an embodiment of the present application, a read-write device determines a first quantity, wherein the first quantity is the number of resource objects available to the answering device, and the resource objects include resources or resource groups, and indicates at least one of the first quantity and a target step length to the answering device, wherein the target step length is a step length used for the answering device to modify a random number, and the target step length is determined based on the first quantity. Then, the answering device can determine whether to respond to the read-write device based on at least one of the above-mentioned first quantity and the target step length, thereby improving the flexibility of inventory.

[0166] Optionally, the target step size is less than or equal to the first number.

[0167] Optionally, the reader / writer device indicates at least one of the first number and the target step length to the answering device, including:

[0168] The read / write device sends a control instruction to the response device;

[0169] The control instruction carries at least one of the first quantity and the target step size, or at least one of the first quantity and the target step size is indicated by a second quantity, and the second quantity is the number of resource objects carrying the control instruction.

[0170] In this embodiment, at least one of the above-mentioned first quantity and the target step length is indicated by a second quantity. For example, the answering device can determine at least one of the above-mentioned first quantity and the target step length by detecting the number of resource objects carrying the control instruction; or, the above-mentioned second quantity can be carried in the control instruction, so that the answering device can determine at least one of the above-mentioned first quantity and the target step length through the second quantity.

[0171] Optionally, the first quantity is equal to the second quantity.

[0172] In this embodiment, the first number is equal to the second number, so that the answering device can conveniently determine the number of resource objects available to the answering device based on the number of resource objects carrying the control instruction.

[0173] In some optional embodiments, the first number may be greater than the second number, or the first number may be less than the second number.

[0176] Here, N is the first number, and the N resource objects are resource objects available to the response device.

[0177] In this embodiment, since the number of resource objects available to the answering device is N, N answering devices are allowed to perform uplink transmission on the above N resource objects. Accordingly, the reading and writing devices need to receive the information sent by the answering devices on the above N resource objects respectively, which can improve the efficiency of inventory.
