[0049] In the description of the present application, unless otherwise specified, “plurality” means two or more.

[0050] Passive internet of things (P-IoT), also known as ambient internet of things (A-IoT), is a network communication technology based on passive terminals. Passive terminals are usually devices that do not require built-in batteries and have no external power cords. Such devices can obtain energy through other means to ensure their normal operation.

[0051] Radio frequency identification (RFID) is a device access technology for passive Internet of Things. The reader exchanges information with the tag (also known as the transponder) through wireless signals. The information exchange process is based on a time division system, and the tag determines the communication channel by reporting a random number.

[0052] Passive IoT devices usually use time-division to exchange information when accessing base stations. The base station and the passive IoT devices respond in a one-to-one manner. For example, in RFID technology, the passive IoT devices report random numbers in a random manner. After receiving the random numbers reported by the passive IoT devices, the base station responds and feedbacks, and determines the channel through the random numbers. The random reporting between the base station and the passive IoT devices can be implemented using the ALOHA algorithm or the Q-select algorithm.

[0053] At present, during the access process of passive IoT devices, there is a message conflict problem when multiple passive IoT devices report, which will lead to inefficient utilization of transmission resources.

[0054] In view of this, in the technical solution provided by the present application, the base station can receive a first feedback message from at least one terminal, and based on the first feedback message of at least one terminal, send a second indication message to at least one terminal. The second indication message is used to indicate the first transmission resource corresponding to the terminal, and the first transmission resources corresponding to different terminals are different. In this way, the base station can indicate different transmission resources for the at least one terminal, thereby avoiding the problem of message conflict when the terminal reports, and improving the utilization efficiency of transmission resources.

[0055] The implementation of the embodiments of the present application will be described in detail below in conjunction with the accompanying drawings.

[0056] Figure 1 This is an architecture diagram of a communication system provided in an embodiment of the present application. Figure 1 As shown, the communication system includes: a base station 101 and a terminal 102.

[0057] The access process between the base station 101 and the terminal 102 includes stages such as inventory, counting, searching and command.

[0058] Exemplarily, the terminal 102 is a passive IoT device, also called a tag in RFID. For example, the terminal 102 may be a wearable device (such as a smart watch, a smart bracelet, a pedometer, etc.), an in-vehicle device (such as a car, a bicycle, an electric car, an airplane, a ship, a train, a passive communication accessory in a high-speed rail, etc.), a virtual reality (VR) device, an augmented reality (AR) device, a passive IoT device in industrial control, a smart home device (such as a refrigerator, a television, an air conditioner, an electric meter, a sensor device in a shelf price tag, etc.), an intelligent robot, a workshop device, a wireless terminal in self-driving, a passive IoT device in remote medical surgery, a passive IoT device in a smart grid, a passive IoT device in transportation safety, a passive IoT device in a smart city, or a passive IoT device in a smart home, etc.

[0059] Since the terminal 102 is a passive IoT terminal and usually has no active reporting capability, the access process between the base station 101 and the terminal 102 is usually actively triggered by the base station 101 and the terminal 102 passively responds.

[0060] Exemplarily, the base station 101 sends a QUERY instruction to the terminal 102 , and the terminal 102 reports a random number used to temporarily identify the terminal 102 to the base station 101 in response to the QUERY instruction.

[0061] The base station 101 sends an ACK instruction to the terminal 102 based on the random number, and the terminal 102 reports the fixed identifier of the terminal 102 in response to the ACK instruction.

[0062] For example, the fixed identifier may be an electronic product code (EPC).

[0063] The base station 101 establishes a communication connection with the terminal 102 according to the fixed identifier.

[0064] It should be pointed out that the various embodiments of the present application can learn from or refer to each other. For example, the same or similar steps, method embodiments, system embodiments and device embodiments can all refer to each other without limitation.

[0065] Figure 2 A flow chart of a communication method provided in an embodiment of the present application. Figure 2 As shown, the method comprises the following steps:

[0066] Step 201: The base station sends a first indication message.

[0067] The first indication message is used to indicate a plurality of candidate transmission resources, and the candidate transmission resources are transmission resources used by the terminal to report the first feedback message.

[0068] Exemplarily, the base station may send the first indication message in the form of a broadcast. Since the base station cannot determine the current terminal status at this time, the base station may indicate multiple candidate transmission resources through the first indication message to facilitate reporting by multiple terminals. The number of candidate transmission resources may be set according to actual conditions, and the type of candidate transmission resources may be time domain, frequency domain, beam, etc., which is not limited in this application.

[0069] The first indication message may include a resource identifier, which is used to represent multiple candidate transmission resources. For example, the base station and the terminal are configured with a mapping table between resource identifiers and candidate transmission resources, and the base station and the terminal determine multiple candidate transmission resources corresponding to the resource identifier based on the mapping table.

[0070] The first indication message may also include terminal screening information. The terminal screening information is used to screen the terminals that report the first feedback message. For example, the terminal screening information may be a range of terminal identifiers, a type of terminal, a cell where the terminal is located, and the like.

[0071] Step 202: The terminal receives a first indication message from a base station.

[0072] The first indication message is used to indicate multiple candidate transmission resources.

[0073] For example, Figure 3 As shown, the terminal may be any one of terminal 1, terminal 2 and terminal 3.

[0074] Step 203: The terminal sends a first feedback message to the base station through a target transmission resource among multiple candidate transmission resources.

[0075] The first feedback message includes a temporary identifier of the corresponding terminal. The terminal may generate a temporary identifier according to a preset algorithm in response to the first indication message.

[0076] In a possible implementation, the terminal may determine the target transmission resource from multiple candidate transmission resources through a preset algorithm, and thus send the first feedback message to the base station through the target transmission resource. For example, the terminal generates a random number according to the number of candidate transmission resources according to a random number generation algorithm, and uses the candidate transmission resource corresponding to the random number as the target transmission resource.

[0077] Exemplary, combined Figure 3, terminal 2 determines time slot 1 as the target transmission resource from multiple candidate transmission resources, and terminal 1 and terminal 3 determine time slot 3 as the target transmission resource from multiple candidate transmission resources.

[0078] In addition, in the case where the first indication message also includes terminal screening information, the terminal can determine whether to respond to the first indication message according to the terminal screening information.

[0079] In a possible implementation manner, when the terminal meets the terminal screening information, a first feedback message is sent to the base station through a target transmission resource among multiple candidate transmission resources.

[0080] In this way, the base station can indicate multiple candidate transmission resources to the terminal through the first indication message, and the terminal sends a first feedback message to the base station through the target transmission resource among the multiple candidate transmission resources. Compared with the one-to-one information interaction method between the base station and the terminal in the related technology, the base station can set the transmission resource interval for the terminal to report the first feedback message, so as to avoid the process being affected by the collision of other message sending and receiving, thereby improving the transmission efficiency.

[0081] Step 204: The base station receives a first feedback message from at least one terminal.

[0082] The first feedback message includes a temporary identifier of the corresponding terminal. The temporary identifier can be used as a unique identifier of the terminal before the base station establishes a communication connection with the terminal.

[0083] Exemplarily, the temporary identifier of the terminal may be a random number generated by the terminal. The number of information bits occupied by the random number may be set according to actual conditions, for example, the number of information bits may be set to the minimum number of information bits under the condition of satisfying the number of terminal devices, thereby reducing the collision probability.

[0084] It should be noted that there may be message conflicts when the terminal reports the first feedback message, such as Figure 3 As shown, in time slot 1, terminal 2 reports the first feedback message to the base station, and the base station successfully receives the first feedback message from terminal 2, that is, time slot 1 is a normal time slot. In time slot 2, no terminal reports the first feedback message, that is, time slot 2 is an empty time slot. In time slot 3, terminal 1 and terminal 3 report the first feedback message through the same transmission resource. Due to the message conflict, the base station fails to successfully receive the first feedback message from terminal 1 and terminal 3, that is, time slot 3 is a contention time slot. At least one terminal in step 204 is Figure 3 In addition, for ease of presentation, Figure 3 The technical solution provided in the present application is described with the transmission resources being time domain resources. The above technical solution of the present application is also applicable to other transmission resources, such as frequency domain resources, beam resources, and a combination of various transmission resources.

[0085] Exemplarily, the base station can generate a matching random code according to the temporary identifier corresponding to the terminal, thereby determining the channel between the at least one terminal and the base station. In this way, for the base station side, the base station can use the terminal with the established channel as the terminal that successfully reports the first feedback message. For the terminal side, the base station can instruct the terminal that successfully reports the first feedback message to switch to a state where the first feedback message is no longer reported. In addition, for the terminal for which the base station fails to successfully receive the first feedback message due to collision or other reasons, it does not participate in the subsequent process and can wait for the base station to execute the next round of access process.

[0086] Step 205: The base station sends a second indication message to the at least one terminal based on the first feedback message of the at least one terminal.

[0087] The second indication message is at least used to indicate the first transmission resource corresponding to the terminal, and the first transmission resources corresponding to different terminals are different.

[0088] The first transmission resource may at least be a transmission resource used by the terminal to report a second feedback message, and the second feedback message includes a fixed identifier of the terminal.

[0089] Exemplarily, there is a mapping relationship between the temporary identifier and the first transmission resource, so that the base station can establish a mapping relationship between the terminal and the first transmission resource through the temporary identifier. Different first transmission resources corresponding to different terminals can avoid collision problems when subsequent terminals perform data transmission through the first transmission resource, thereby improving the success rate of data transmission.

[0090] It should be noted that the base station can send the second indication message to the at least one terminal in a variety of ways. For example, the base station can send a second indication message in the form of broadcasting, and the second indication message includes a temporary identifier and a first transmission resource corresponding to at least one terminal. For another example, the base station can send the second indication message to each of the at least one terminal in a parallel transmission manner, and the second indication message includes the temporary identifier and the first transmission resource of the corresponding terminal.

[0091] For example, Figure 3 As shown, since the base station receives the first feedback message of terminal 2, the base station sends a second indication message to terminal 2 based on the temporary identifier corresponding to terminal 2. The second indication message is used to instruct terminal 2 to report the first transmission resource used for the second feedback message.

[0092] Step 206: The terminal receives a second indication message from the base station.

[0093] The second indication message is used to indicate the first transmission resource corresponding to the terminal, and the first transmission resources corresponding to different terminals are different.

[0094] For example, Figure 3 As shown, the terminal in step 206 may be Figure 3 Terminal 2 in.

[0095] Step 207: The terminal sends a second feedback message to the base station through the first transmission resource.

[0096] The second feedback message includes a fixed identifier of the terminal. The fixed identifier may be a unique identifier used to characterize the actual device information of the terminal, such as an EPC code. In this way, after receiving the second feedback message, the base station may obtain the corresponding relationship of the terminal from the background server according to the fixed identifier, thereby establishing a communication connection between the base station and the terminal.

[0097] Based on the above technical solution, the base station can send a first indication message so that the terminal can provide feedback through multiple candidate transmission resources indicated in the first indication message. After that, the base station receives the first feedback message from at least one terminal, and based on the first feedback message of at least one terminal, sends a second indication message to at least one terminal. The second indication message is used to indicate the first transmission resource corresponding to the terminal, and the first transmission resources corresponding to different terminals are different. In this way, after receiving the second indication message from the base station, the terminal can send a second feedback message to the base station through the first transmission resource. In other words, the base station can indicate different transmission resources for the at least one terminal, thereby avoiding the problem of message conflict when the terminal reports a fixed identifier, and improving the utilization efficiency of transmission resources.

[0098] Before the base station sends the second indication message to the terminal, the base station may also determine a first transmission resource corresponding to each terminal.

[0099] The following introduces a process in which the base station determines the first transmission resource.

[0100] As a possible embodiment of the present application, Figure 2 ,like Figure 4 As shown, the method further includes step 401.

[0101] Step 401: The base station determines a first transmission resource corresponding to each terminal.

[0102] In a possible implementation manner, the base station may determine a priority order of at least one terminal, and determine a first transmission resource corresponding to each terminal based on the priority order.

[0103] Exemplarily, the base station may determine the priority order according to at least one of the types of the terminals, the order of receiving the first feedback messages, and the temporary identifiers of the terminals.

[0104] In addition, due to signal interference, fluctuation, clock jitter and other reasons, the terminal may not be able to successfully report the second feedback message. Therefore, the at least one terminal may be divided into a first terminal that reports successfully and a second terminal that does not report successfully.

[0105] The following describes two situations: successful reporting and unsuccessful reporting.

[0106] As a possible embodiment of the present application, Figure 2 ,like Figure 5 As shown, for the case of successful reporting, the method further includes step 501.

[0107] Step 501: A base station receives a second feedback message from a first terminal.

[0108] The second feedback message includes the fixed identifier of the terminal. That is, the first terminal is a terminal that successfully reports the fixed identifier among the at least one terminal.

[0109] In this way, the base station can establish a communication connection with the first terminal based on the fixed identifier.

[0110] Exemplarily, the base station may issue a control command to the first terminal with which the communication connection has been established, such as controlling the start / stop of the terminal, modifying a field in the terminal memory, etc. Taking the first terminal as an electronic price tag as an example, the base station may modify the displayed price of the electronic price tag.

[0111] As another possible embodiment of the present application, in combination with Figure 2 ,like Figure 5 As shown, for the case of unsuccessful reporting, the method further includes steps 502 to 504.

[0112] Step 502: The base station sends a third indication message to the second terminal.

[0113] The second terminal is a terminal that fails to successfully report the fixed identifier among the at least one terminal. The third indication message is used to indicate the second transmission resource corresponding to the second terminal, and different second terminals correspond to different second transmission resources.

[0114] Exemplarily, the base station may regard the terminal that has not received the corresponding second feedback message within the preset time as the second terminal, and send a third indication message to the second terminal based on the temporary identifier of the second terminal. The third indication message has the same function as the second indication message, and the main difference is that the target object to which it is sent is different.

[0115] like Figure 3 As shown, terminal 2 fails to report the second feedback message, and the base station sends a third indication message to terminal 2 to instruct terminal 2 to report the fixed identifier again.

[0116] The second transmission resource is a transmission resource used by the second terminal to report the third feedback message. The third feedback message includes a fixed identifier of the second terminal.

[0117] The second terminal that fails to report the fixed identifier is further configured to execute the following steps 503 to 504.

[0118] Step 503: The terminal receives a third indication message from the base station.

[0119] The third indication message is used to indicate the second transmission resource corresponding to the terminal, and different terminals correspond to different second transmission resources. The terminal is the second terminal that has not successfully reported the fixed identifier.

[0120] Step 504: The terminal sends a third feedback message to the base station through the second transmission resource.

[0121] The third feedback message includes the fixed identifier of the terminal. The third feedback message has the same function as the second feedback message, and is used to report the fixed identifier of the terminal.

[0122] It should be noted that the base station and the terminal can repeat the above steps so that the terminal can successfully report the fixed identifier and thus establish a communication connection with the base station. Afterwards, the base station can command control to the terminal that has established the communication connection, or trigger the next round of terminal access process.

[0123] Based on the above technical solution, the base station in the present application can establish a communication connection for the first terminal that successfully reports the fixed identifier, thereby realizing the corresponding instruction control, and can initiate a third instruction message again for the second terminal that fails to successfully report the fixed identifier until the second terminal successfully reports the fixed identifier. This solution can effectively improve the success rate of terminal access, simplify the terminal access retransmission process, and improve access efficiency.

[0124] The embodiment of the present application can divide the communication device into functional modules or functional units according to the above method example.
