[0036] To facilitate a clearer understanding of the technical solutions provided in the embodiments of this application, some related knowledge is introduced as follows.

[0037] I. AIoT devices.

[0038] AIoT is an Internet of Things (IoT) service. Among them, IoT terminals are powered by energy harvesting. The IoT terminals have no battery or have limited energy storage capabilities (for example, using a capacitor). The energy sources for energy harvesting include radio waves, light, motion, heat, or other suitable energy sources.

[0039] Low-power IoT devices are a type of IoT device. The overall power consumption of such devices is relatively low, including low-power signal reception and low-power signal transmission. Due to the relatively low overall power consumption, the energy for communication can come from the environment, such as wind energy, kinetic energy, thermal energy, RF signals, etc. Low-power IoT devices can also be referred to as AIoT devices or passive IoT devices. AIoT devices have ultra-low complexity and ultra-low power consumption.

[0040] The signal transmission method of AIoT devices is as follows:

[0041] 1) It can use backscattered radio frequency (RF) signals for signal transmission; such devices can also be called electronic tags or radio frequency identification (RFID) tags.

[0042] 2) Some active tags have the ability to generate active signals, but to achieve low power consumption of the device, it is generally below 0 dBm, for example, less than or equal to -10 dBm.

[0043] AIoT terminals can be classified based on energy source, energy storage capability, passive or active transmission, etc. AIoT devices include the following types:

[0044] a) Device Type A: Belongs to passive devices. Devices of this type have no energy storage, no independent signal generation or amplification, that is, backscatter transmission.

[0045] b) Device Type B: A semi-passive device, also belonging to the general category of passive devices. Devices of this type have energy storage and no independent signal generation, that is, backscatter transmission. Among them, the use of stored energy can include amplification of the reflected signal.

[0046] c) Device Type C: Belongs to active devices. Devices of this type have energy storage and independent signal generation, that is, active RF components for transmission.

[0047] II. Information transmission between the reader and the tag in RFID.

[0048] RFID is a backscatter communication system, and its main design goal is to identify the ID and read data of the base station controller (BSC) devices (i.e., Tags) within the coverage of the reader. Since RFID was initially applied to the automated inventory of a large number of goods, the process of identifying and reading data from Tags is also called inventory.

[0049] Taking the EPC C1G2 RFID system defined by ISO 18000-6c as an example, Figure 2It is a schematic diagram of the process for a Tag to receive and send data provided by an embodiment of the present application. Refer to Figure 2 As shown, after the Interrogator sends a Query instruction in Continuous Wave (CW), the Tag responds with a Reply. Taking Reply as RN16 as an example, the Tag generates a 16-bit random number and sends it to the Interrogator. Then, after the Interrogator sends this sequence to the Tag via an ACK instruction, and after the Tag successfully verifies the RN16 in the ACK, it sends subsequent data, such as Protocol Control (PC) / Extended Protocol Control (XPC), Electronic Product Code (EPC), 16-bit CRC Check (PacketCRC), etc., to the Interrogator.

[0050] Among them, T1 represents the time from the Interrogator sending to the Tag's response, T2 represents the time from the Tag's response to the Interrogator sending, and T4 represents the interval of the minimum Interrogator command.

[0051] If the data sent to the Interrogator is valid, the Interrogator sends QueryRep to indicate entering the next time slot; if the data sent to the Interrogator is invalid, the Interrogator sends a NAK (Turnaround Truncation) instruction.

[0052] Functionally, the operation instructions of the reader can be divided into three categories: Select, Inventory, and Access commands. In addition, for future command expansion, different-length encodings are reserved for use. Specifically, refer to Table 1 shown below, which shows the operation instructions of the reader.

[0056] Specifically, refer to Table 2 shown below, which shows the operation instructions of the Tag.

[0057] Table 2

[0058]

[0059] Currently, in 3GPP technology, there is no ready-made support for the service process of AIoT devices. Therefore, it is necessary to rely on the 3GPP technical framework to introduce the services of AIoT devices to obtain reliable coverage and success rate with low signaling overhead. And considering the extremely low power consumption requirements and extremely simple characteristics of AIoT devices, the design goals of device simplification and small system overhead should be considered as much as possible.

[0060] The objective of this application is to introduce a process in the 3GPP system framework to support the execution of relevant services by AIoT devices. Based on the above objective, embodiments of this application provide a data transmission method, apparatus, first terminal, and first device to ensure the feasibility and efficiency of signaling transmission by AIoT devices in the 3GPP system framework. At the same time, it is also necessary to expand the coverage of AIoT devices, so as to reduce the power consumption and complexity of AIoT devices while ensuring the transmission effect, and reduce network overhead and improve system efficiency.

[0061] The following will, with reference to the accompanying drawings, elaborate on the data transmission method provided by embodiments of this application through some embodiments and their application scenarios.

[0062] Figure 3 is one of the flow diagrams of the data transmission method provided by embodiments of this application. As Figure 3 shown, this method includes step 301; where:

[0063] Step 301, the first terminal obtains a first command sent by the first device; the first terminal is an environment energy-enabled Internet of Things AIoT device, the first command is carried on a specific common control channel, and the first command is used to assist the first terminal in executing the target service.

[0064] It should be noted that embodiments of this application can be applied to scenarios where the first terminal (i.e., the AIoT device) executes the target service in the 3GPP technology framework. Among them, the target service can be an inventory service, a location or home network reporting service, etc.

[0065] For example, when the target service is an inventory service, each AIoT device needs to respond to the first device when receiving the first command (also known as the inventory command) sent by the first device, so that the first device can determine the number of AIoT devices.

[0066] For another example, when the target service is a location or home network reporting service, each AIoT device needs to respond to the first device when receiving the first command sent by the first device, so that the first device can determine the latest location or home network of each AIoT device.

[0067] Optionally, the first device includes at least one of a network-side device and a second terminal; the second terminal is a terminal used to send the first command to the first terminal.

[0068] In embodiments of this application, the role of the second terminal is equivalent to that of a reader in RFID. Both the network-side device and the second terminal can send the first command to the AIoT device, so that the AIoT device responds to the first command and executes the target operation.

[0069] Among them, the first command is carried in a specific (also known as dedicated) Common Control Channel (CCCH). The specific CCCH is scheduled by a specific Radio Network Temporary Identity (RNTI). Different types of AIoT devices or different types of target services can use different specific CCCHs. The AIoT device responds to the requirements of the network-side device or the second terminal by reading the first command of the corresponding specific CCCH.

[0070] It should be noted that the focus of the embodiments of this application is to provide an efficient transmission method for the target service process of a large number of AIoT devices within the 3GPP technical framework, achieving design goals such as small network overhead, low complexity and low power consumption of AIoT devices, and high system efficiency.

[0071] Since the essence of the target service is a request-response process initiated by the first device for a large number of AIoT devices, using common signaling to send the first command, that is, the request signaling, is a relatively efficient way. One request signaling can enable a large number of AIoT terminals to receive simultaneously, and by repeating the sending of the first command, it can ensure a wider coverage of AIoT devices and the probability of correct reception of the first command by AIoT. Moreover, through the above method, it better takes into account the Radio Resource Control (RRC) state of AIoT devices, does not require AIoT devices to support or enter the RRC connected state (RRC CONNECTED) for reception, reduces the complexity of AIoT devices and the signaling overhead of state transitions, and improves the overall efficiency, capacity, and coverage of the network.

[0072] The specific CCCH can be called the Inventory Control Channel (ICCH). The network-side device or the second terminal can carry the first command in the ICCH and send it to the AIoT device. The following embodiments will be further described by taking the specific CCCH as the ICCH and the first command as the inventory command as an example.

[0073] In practical applications, the first device can send an inventory command to a specific service group or a specific device group through the ICCH. Among them, the specific service group includes one or more AIoT devices, all of which perform the same target service. For example, multiple AIoT devices in the specific service group are all used for inventory of logistics express items, inventory of warehouse goods, or inventory of ranch organisms, etc.

[0074] The specific device group includes one or more AIoT devices, all of which belong to the same type of AIoT device. For example, multiple AIoT devices in the specific device group are all Passive B-type devices, or all Active C-type devices, etc.

[0075] That is to say, AIoT devices are divided into different dimensions such as "service type" and "device type". The "service type" refers to the service type that the AIoT device is interested in or involved in. It should be noted that the classification dimension of AIoT devices can be changed according to business requirements, and this application does not specifically limit the dimensions of AIoT devices.

[0076] In the data transmission method provided by the embodiments of this application, the AIoT device obtains the first command sent by the first device through a specific common control channel, enabling the AIoT device to respond to the first command on demand and execute the target service, ensuring the success rate of the AIoT device receiving the first command, and thus guaranteeing the feasibility and efficiency of the AIoT device in performing signaling transmission within the 3GPP technical framework, providing a feasible solution for the AIoT device to execute the target service within the 3GPP technical framework.

[0077] ICCH is a new common control channel, so other basic control signaling is needed to notify the AIoT device of the scheduling information and attribute information of ICCH, etc.

[0078] Optionally, before the first terminal obtains the first command sent by the first device, the following steps also need to be executed:

[0079] The first terminal receives the common control channel configuration information sent by the first device.

[0080] Specifically, the common control channel configuration information is the configuration information corresponding to ICCH. When the first device sends the first command to at least one AIoT device through ICCH, the AIoT device can obtain the scheduling information of its corresponding ICCH based on the configuration information corresponding to ICCH, and listen to the specific location of ICCH according to the rules, read the first command in ICCH, and execute the target service as needed.

[0081] Optionally, the common control channel configuration information is carried in the System Information Block (SIB). The first device can notify the configuration information of ICCH in the SIB. Correspondingly, the AIoT device can obtain the scheduling information of its corresponding ICCH by reading the SIB; among them, the scheduling information of ICCH, such as scheduling period, repetition period, modification period, transmission parameters, etc., is carried in the SIB.

[0082] For example, when an AIoT device accesses a cell, it obtains downlink synchronization according to the process, reads the MIB and SIB1, and can further learn from SIB1 whether the cell supports the SIB corresponding to ICCH (referred to as SIB x). If SIB x is currently in the broadcast state, the AIoT device obtains the ICCH configuration information by reading SIB x. If SIB x is currently in the on-demand state, the AIoT device can initiate a request to obtain SIB x from the network device, for example, through the Msg 1 or Msg 3 based ondemand SI request process, and then reads SIB x to obtain the ICCH configuration.

[0083] Optionally, the public control channel configuration information includes at least one of the following:

[0084] a) The service type corresponding to the public control channel.

[0085] For example, the service type corresponding to ICCH[A] can be the inventory of logistics express items, ICCH[B] can be the inventory of airport luggage, ICCH[C] is the inventory of warehouse goods, ICCH[D] is the inventory of ranch organisms, etc.

[0086] b) The type of the AIoT device corresponding to the public control channel.

[0087] For example, ICCH[A] is for Passive B type AIoT devices, ICCH[B] is for Active C type AIoT devices, etc.

[0088] c) A specific radio network temporary identifier RNTI, and the specific RNTI is used to schedule the public control channel.

[0089] Specifically, the specific RNTI can be represented as, for example, an Inventory Radio Network Temporary Identifier (IV-RNTI). The first device uses the IV-RNTI corresponding to ICCH to schedule the bits in the Downlink Control Information (DCI) to indicate whether there is a new first command, such as an inventory command.

[0090] It should be noted that in actual applications, there may be different service types and different types of AIoT devices. Therefore, the target services (such as inventory services) performed by AIoT have diverse characteristics. For example, there are different requirements for the arrival cycle, required latency, reliability, or coverage of the inventory service.

[0091] Therefore, multiple ICCHs can be used according to actual needs to address different inventory requirements. In this way, for each inventory service, different IV-RNTIs are required for differentiation, so that different types of AIoT devices or AIoT devices interested in different types of inventories can listen to different IV-RNTIs correspondingly, facilitating them to quickly find the inventory services they are interested in and avoiding power consumption caused by listening to other irrelevant services.

[0092] In summary, by configuring the IV-RNTI, the energy consumption of AIoT devices for listening to useless scheduling can be further reduced, enabling AIoT devices to only wake up at necessary positions to listen to the first command, thus greatly reducing the power consumption of AIoT devices.

[0093] It should be noted that the functions of configuring the above common control channel configuration information a)-c) are as follows: Assuming there are ICCHs corresponding to different target services (such as different inventory services) in a cell or carrier, it is necessary to distinguish the ICCHs based on the above common control channel configuration information a)-c) to facilitate AIoT devices to identify the ICCHs corresponding to or interested in themselves.

[0094] In another implementation, when there is only one ICCH in a cell or carrier, the IV-RNTI corresponding to this ICCH can adopt the method specified by the standard and directly specify a value. The service type corresponding to this ICCH and the type of AIoT device can be explicitly carried, or other default or specified methods can also be adopted.

[0095] For example, if a dedicated carrier is reserved for logistics services, then there is only a need for an ICCH for logistics inventory on this carrier. Logistics-related AIoT devices can obtain the configuration of the corresponding ICCH as long as they find the corresponding carrier in a predictable manner.

[0096] d) The transmission period information of the common control channel.

[0097] Specifically, the purpose of setting the period information is as follows: On the one hand, taking into account the power-saving requirements of AIoT devices, they only wake up to listen at the moments or windows when AIoT devices are needed, and can enter the sleep state during other periods to save energy; on the other hand, considering meeting the delay characteristics of the target services of AIoT, the longer the sleep time or proportion of AIoT devices, the longer the delay from the arrival of a target service demand to its response. In addition, performance indicators such as the coverage of AIoT devices, the reliability and success rate of signaling transmission also need to be considered. In practical applications, repeated transmission is a typical way to improve performance.

[0098] Optionally, the transmission period information includes at least one of the following:

[0099] [a], The scheduling period is used for the first device to schedule the common control channel within the scheduling period.

[0100] For example, the scheduling period of the ICCH is N radio frames, sub-frames or time slots. It should be noted that generally, the counted sub-frames or time slots should be based on the downlink (DL) sub-frames or time slots, because only DL sub-frames or time slots can monitor the downlink scheduling of the Physical Downlink Control Channel (PDCCH), or a counting method is agreed to ensure that both the transceiver ends understand and agree accurately.

[0101] In the scheduling period, a "scheduling start time" parameter is configured. This parameter can explicitly indicate the specific position within each scheduling period, such as the offset x relative to the start position of the scheduling period. Or, if the "scheduling start time" parameter is not configured in the scheduling period, the scheduling start time defaults to 0, that is, the start position of each period is the scheduling start time.

[0102] [b], The scheduling window corresponding to the scheduling period is used for the first device to schedule the common control channel within the scheduling window.

[0103] The configuration of the scheduling window serves to leave a certain flexible space for the scheduling of the first device (such as the network-side device). For example, if the window is configured as m time slots, then the AIoT device needs to continuously monitor m time slots or downlink time slots starting from the scheduling start time in each period, and can receive scheduling within this scheduling window. If the scheduling window is not configured, it is default that the AIoT device only listens for scheduling once at the time slot of the scheduling start time.

[0104] [c], At least one repetition period corresponding to the scheduling period is used for the first device to repeatedly schedule the common control channel within the repetition period.

[0105] The repetition period, for example, can design the following parameters: the period length of the repetition period, the start position within the scheduling period, etc. By configuring the repetition period, the same scheduling of the ICCH can be sent repeatedly several times. Through the above method, the network coverage and the receiving reliability and success rate are improved.

[0106] For example, the scheduling period is 24 radio frames (240 ms), and the repetition period can be 4 radio frames (40 ms). That is, there are 6 repetition periods within one scheduling period, and the same ICCH can be sent repeatedly, which is convenient for improving the coverage and receiving accuracy.

[0107] [d], The modification period is used to characterize the range where the common control channel is allowed to change or take effect.

[0108] The modification period is defined as the period during which ICCH is allowed to change or the effective range. In practical applications, the modification period is generally larger, greater than the range of the above scheduling period and repetition period.

[0109] For example, the modification period can reach the second level. It can be stipulated that the ICCH within a modification period is the same and not allowed to change until a new ICCH inventory process can be initiated in the next modification period; or, it can be stipulated that the ICCH inventory commands received by the AIoT device within a modification period only need to be responded to once, and it will only be regarded as a new inventory and responded to again until a new ICCH inventory is received in the next modification period.

[0110] In practical applications, there are two-level cycle configurations: larger cycles such as the modification period or the scheduling period are stipulated that ICCH is not allowed to change within this period, or only the same content of ICCH or the first command (such as the inventory command) is allowed to be sent within this period; smaller cycles such as the repetition period, generally the large cycle is an integer multiple of the small cycle. The repetition period within the large cycle is for sending the same ICCH or the content of the first command multiple times, facilitating the AIoT device to obtain gain improvements in coverage and success rate through multiple decodings, or even combined decoding.

[0111] It should be noted that in addition to allocating different ICCH channels or different IV-RNTIs to different service types or different types of AIoT devices, different service types or different types of AIoT devices can also be represented by different positions of the scheduling period.

[0112] For example, for the same ICCH channel and the same IV-RNTI, the ICCH scheduled at even cycle positions is for a group of AIoT devices of service type [A] or type [B]; the ICCH scheduled at odd cycle positions is for a group of AIoT devices of service type [C] or type [D].

[0113] It can be understood that the above classification using odd and even cycles can divide the above service types or AIoT device types into two groups. If it is necessary to divide the above service types or AIoT device types into more groups, different groups can be corresponding to different remainders of the modulo n of the scheduling period.

[0114] In summary, by configuring the periodic information, the power consumption of the AIoT for listening to useless scheduling can be further reduced, enabling the AIoT device to wake up and listen for the inventory command only at necessary positions, greatly reducing the device power consumption. Moreover, by setting the periodic information, the feasibility and efficiency of signaling transmission are ensured, the coverage of the AIoT device is extended, the power consumption and complexity of the AIoT device are reduced while ensuring the transmission effect, the network overhead is reduced, and the system efficiency is improved.

[0115] e) Transmission parameters of the public control channel.

[0116] Specifically, the role of configuring the transmission parameters is: to reduce the decoding complexity of the AIoT device, some transmission parameters are configured for the AIoT device in a semi-static manner, which is convenient for the AIoT device to parse.

[0117] Optionally, the transmission parameters include at least one of the following:

[0118] [a] Transmission bandwidth information;

[0119] [b] Search space information;

[0120] [c] Modulation and coding format.

[0121] f) Information of the wake-up signal, which is used to wake up the first terminal to listen to the public control channel.

[0122] Optionally, the information of the wake-up signal includes at least one of the following:

[0123] [a] Whether the wake-up signal is supported.

[0124] The wake-up signal is, for example, a specific indication information, expressed as "Inventory Present Early Indication (IPEI)". The first device (such as a network-side device) uses IPEI to indicate whether there is a new inventory command.

[0125] [b] The position of the wake-up signal.

[0126] The role of configuring the wake-up signal is: to enable the AIoT device to save more power. Before each period when the AIoT device needs to wake up and listen, it can first listen to the wake-up signal. If the wake-up signal is detected, the terminal wakes up to listen to the subsequent ICCH scheduling. If not, the terminal can continue to sleep later, indicating that there is no ICCH scheduling. The AIoT device listens to the wake-up signal using a receiving device or method with lower power consumption, so it can save more power.

[0127] If a wake-up signal is configured, it generally appears before the period that needs to be woken up. For example, by configuring the delta parameter value, which indicates the offset of the wake-up signal relative to the start position of other known periods, or the independent period and position of the wake-up signal can also be directly configured.

[0128] Optionally, the first terminal obtains a first command sent by the first device, which can be specifically implemented through the following steps:

[0129] Step 1), the first device monitors the common control channel based on the common control channel configuration information;

[0130] Step 2), when the first device monitors the common control channel, the first terminal obtains the first command from the common control channel.

[0131] In the following embodiments of the present application, it will be further described how the AIoT device receives the ICCH and obtains the first command in the ICCH, so that the AIoT device can make an expected response.

[0132] Optionally, the first device monitors the common control channel based on the common control channel configuration information, which can be specifically implemented in any of the following ways:

[0133] Method 1, when the first terminal starts subsequent monitoring based on the indication of the wake-up signal, the first terminal monitors the common control channel based on the transmission period information.

[0134] For example, the AIoT device periodically monitors the position of the IPEI. When the IPEI is detected, it indicates that the AIoT device starts subsequent monitoring. Or, the AIoT device periodically monitors the position of the IPEI. When the IPEI is detected and the IPEI indicates that the AIoT device starts subsequent monitoring, the AIoT device starts subsequent monitoring, that is, the AIoT device starts subsequent monitoring of the ICCH.

[0135] That is to say, the AIoT device monitors the IPEI. When it is determined that there is an ICCH scheduling in the subsequent period, the AIoT device monitors the ICCH at the scheduling window position configured in the indicated period. This period can be the position of the first repeating period of the next modification period, or the position of the next repeating period adjacent to the wake-up signal. The specific position of the period can be set according to actual service requirements and is not limited here.

[0136] Optionally, when the wake-up signal indicates that there is no scheduling of the common control channel in the subsequent period, the first terminal enters the sleep state.

[0137] Specifically, when the wake-up signal does not appear or there is no ICCH scheduling in the subsequent cycle of the wake-up signal content display, the AIoT device directly enters the sleep state until the next wake-up signal position to determine again whether to start subsequent monitoring.

[0138] Method 2: The first terminal monitors the common control channel based on the transmission cycle information.

[0139] In the embodiment of the present application, if the information of the wake-up signal is not configured in the ICCH configuration, the AIoT device needs to monitor the possible ICCH scheduling at the specified position according to the transmission cycle information.

[0140] In the above embodiment, the AIoT device monitors the ICCH based on the transmission cycle, which can further reduce the energy consumption of the AIoT device for monitoring useless scheduling, enabling the AIoT device to only wake up at the necessary positions to monitor the first command, greatly reducing the device power consumption.

[0141] Optionally, the first terminal monitors the common control channel based on the transmission cycle information, which can be specifically implemented by at least one of the following methods a - b:

[0142] Method a: The first terminal monitors the common control channel based on the specific RNTI and the transmission cycle information.

[0143] Optionally, the above method a includes the following two situations:

[0144] Situation 1: The first terminal monitors the scheduling of the specific RNTI within the first repetition period of each modification period.

[0145] In the above Situation 1, for each modification period, the AIoT device monitors the scheduling of the IV-RNTI at the scheduling position or within the scheduling window of the first repetition period within the modification period to determine whether there is an ICCH in this modification period.

[0146] In practical applications, if a new ICCH or the first command is specified, it is only allowed to start the initial transmission at the boundary of the modification period or the scheduling period, and the same ICCH information is repeatedly transmitted multiple times within the repetition period of the entire modification period. In the above situation, the AIoT device needs to monitor the scheduling of the IV-RNTI at the scheduling position or within the scheduling window of the first repetition period within each modification period to determine whether there is an ICCH in this modification period.

[0147] For each modification period, if there is a scheduling of the IV-RNTI, or the DCI of the IV-RNTI indicates that there is a new ICCH in the subsequent period, the AIoT device knows that there is a new ICCH or a first command sent in this modification period. At this time, the AIoT device starts to listen for and read the ICCH, or through multiple attempts, successfully reads the content of the first command, and responds as needed according to its actual situation to execute the target service. Then, the AIoT device can enter the sleep state until the end of this modification period or scheduling period.

[0148] If there is no scheduling of the IV-RNTI, or the DCI of the IV-RNTI indicates that there is no new ICCH in the subsequent period, the AIoT device performs the target operation, that is, the AIoT device directly enters the sleep state until the end of this modification period or scheduling period. The above content is repeated in the next modification period.

[0149] Situation 2: The first terminal listens for the scheduling of the specific RNTI within each repetition period of each modification period.

[0150] In the above Situation 2, for each modification period, the AIoT device listens for the scheduling of the IV-RNTI at the scheduling position or scheduling window within each repetition period of the modification period to determine whether there is an ICCH in this modification period.

[0151] In practical applications, if a new ICCH or a first command is specified, it is allowed to start the initial transmission at any repetition period position of the modification period or scheduling period, and the same ICCH information is repeatedly transmitted multiple times within the repetition periods of the entire modification period. In the above situation, the AIoT device needs to listen for the scheduling of the IV-RNTI at the scheduling position or scheduling window within each repetition period of each modification period to determine whether there is an ICCH in this modification period.

[0152] For each modification period, if there is a scheduling of the IV-RNTI, or the DCI of the IV-RNTI indicates that there is a new ICCH in the subsequent period, the AIoT device knows that there is a new ICCH or a first command sent in this modification period. At this time, the AIoT device starts to listen for and read the ICCH, or through multiple attempts, successfully reads the content of the first command, and responds as needed according to its actual situation to execute the target service. Then, the AIoT device can enter the sleep state until the end of this modification period or scheduling period.

[0153] If there is no scheduling of the IV-RNTI, or the DCI of the IV-RNTI indicates that there is no new ICCH subsequently, the AIoT device performs the target operation, that is, the AIoT device needs to continue to monitor whether there is scheduling of the IV-RNTI in each repetition period until the end of the modification period or the scheduling period. The above content is repeated in the next modification period.

[0154] In manner b, the first terminal monitors the common control channel based on the notification message and the transmission period information.

[0155] Optionally, the notification message includes at least one of the following:

[0156] a) The first notification message, indicating the existence of the common control channel in the next modification period;

[0157] b) The second notification message, indicating the existence of the common control channel in the current modification period.

[0158] Optionally, the above manner b includes the following two situations:

[0159] Situation 1: After the first terminal monitors the first notification message in the previous modification period, it starts to monitor the common control channel at the boundary of the current modification period.

[0160] In the above Situation 1, the AIoT device determines whether there is an ICCH in the current modification period according to whether it monitors the first notification message in the previous modification period.

[0161] In practical applications, the notification method of the first notification message can be related to the transmission period information of the ICCH.

[0162] For example, in the previous modification period, it is necessary to read the scheduling position of the first notification message in m repetition periods, and m is generally less than the number of repetition periods included in a modification period. For example, if a modification period includes 16 repetition periods, then at the positions of 3 repetition periods among them, the AIoT device needs to detect whether there is a first message notification. Among them, these 3 repetition period positions can be agreed upon or selected by the AIoT device itself. For the first device (such as the network side device), it is necessary to try to send the first notification message to all AIoT devices.

[0163] In another implementation manner, the notification method of the first notification message can also be independent of the transmission period information of the ICCH.

[0164] For example, the AIoT device listens for the first notification message according to a fixed paging position. Since the AIoT device needs to wake up to listen for paging, the first notification message that appears in the ICCH can be sent in coordination with paging.

[0165] In practical applications, if a new ICCH or a first command is specified, only the initial transmission is allowed to start at the boundary of the modification period or the scheduling period, and within the repetition period of the entire modification period, the same ICCH information is repeatedly transmitted multiple times. In the above situation, when the AIoT device monitors the first notification message that appears in the ICCH in the previous modification period, it starts listening for the ICCH scheduling window and position from the boundary of the current modification period to read the first command; or, it succeeds only after multiple attempts in multiple repetition periods, reads the content of the first command, and responds as needed according to its actual situation to execute the target task; then, the AIoT device can enter the sleep state until the end of the modification period or the scheduling period.

[0166] It should be noted that if the first notification message that appears in the ICCH is not received in the previous modification period, the current modification period only listens for the first notification message and does not need to listen for the ICCH. The above content is repeated in the next modification period.

[0167] Situation 2: After the first terminal monitors the second notification message in the current modification period, it starts listening for the common control channel in the next repetition period of the current modification period.

[0168] In the above Situation 2, the AIoT device determines whether there is an ICCH in the current modification period based on whether the second notification message is monitored in the current modification period.

[0169] In practical applications, the notification method of the second notification message can be related to the transmission period information of the ICCH.

[0170] For example, within the current modification period, it is necessary to read the scheduling positions of the second notification message in m repetition periods, and m is generally less than the number of repetition periods included in a modification period. For example, if a modification period includes 16 repetition periods, then at the positions of 3 of these repetition periods, the AIoT device needs to detect whether there is a second message notification. Among them, these 3 repetition period positions can be agreed upon or selected by the AIoT device itself. For the first device (such as a network-side device), it is necessary to try to send the second notification message to all AIoT devices.

[0171] In another implementation, the notification method of the second notification message can also be independent of the transmission period information of the ICCH.

[0172] For example, the AIoT device listens for the second notification message according to a fixed paging position. Since the AIoT device needs to wake up to listen for paging, the second notification message that appears on the ICCH can be sent in coordination with paging.

[0173] In practical applications, if a new ICCH or the first command is specified, it is allowed to start the initial transmission at any repetition cycle position within the modification cycle or the scheduling cycle, and within the repetition cycles of the entire modification cycle, the same ICCH information is repeatedly transmitted multiple times. In the above situation, when the AIoT device listens for the second notification message that appears on the ICCH in the current modification cycle, it starts listening for the ICCH scheduling window and position from the next repetition cycle of the current modification cycle to read the first command; or, it succeeds only after multiple attempts in multiple repetition cycles, reads the content of the first command, and responds as needed according to its actual situation to execute the target service. Then the AIoT device can enter the sleep state until the end of the modification cycle or the scheduling cycle.

[0174] If the second notification message that appears on the ICCH is not received in the current modification cycle, there is no need to listen for the ICCH, and continue to listen for the second notification message in the next cycle. Repeat the above content in the next modification cycle.

[0175] Optionally, the first terminal obtains the first command from the common control channel, which can be specifically implemented through the following steps:

[0176] The first terminal decodes the common control channel, and reads the first command in the common control channel when the decoding is successful.

[0177] Specifically, when the AIoT device decodes the ICCH and successfully decodes the first command in the ICCH, it responds as needed according to the actual situation of the AIoT device to execute the target service.

[0178] Optionally, the first terminal decodes the common control channel, and reads the first command in the common control channel when the decoding is successful, including:

[0179] The first terminal decodes the common control channel in at least one repetition cycle until the decoding of the common control channel is successful, and then reads the first command in the common control channel.

[0180] Specifically, if the AIoT device fails to decode the ICCH in the previous repetition period, it can continue to read the next repetition period until it successfully decodes the content of the first command in the ICCH, and then respond as needed according to its actual situation to execute the target service.

[0181] After the AIoT device successfully reads the ICCH and responds as needed, if it is specified that there will be only one new ICCH or new first command sent within a modification period or a scheduling period, the AIoT device can enter the sleep state until the end of the modification period or the scheduling period, and start listening for the ICCH at the next wake-up signal position or the position specified in the transmitted periodic information.

[0182] Optionally, when the first terminal fails to decode the common control channel, the first terminal reports first information to the first device; the first information is used to indicate that the first terminal cannot obtain the first command or the link fails.

[0183] Specifically, if the AIoT device fails to successfully decode the ICCH throughout the modification period or the scheduling period, that is, after repeated listening in multiple repetition periods, the AIoT device still fails to successfully decode the first command in the ICCH, it indicates that there is a coverage problem for the AIoT device here. The AIoT device can report the first information to the first device (such as a network-side device) to indicate the coverage problem of the AIoT device.

[0184] If the AIoT device has the ability to actively send uplink data, it can report through the active uplink process. If the AIoT device cannot actively send uplink data, it waits for the next or specified DL trigger to perform uplink reporting.

[0185] In the above embodiments, if it is allowed that the ICCH appears only at the boundary of a large period, such as at the boundary of a modification period or a scheduling period, the advantage is that the AIoT device is more power-saving, but the delay for the first command to arrive and be responded to is longer. If it is allowed that the ICCH appears in a small period, such as in a scheduling window within a repetition period, the disadvantage is that the energy consumption of the AIoT device is high, but the advantage is that the delay for the first command to arrive and be responded to is shorter. Therefore, a suitable ICCH listening method can be configured or agreed according to at least one of different device types and service requirements of the AIoT device. Or, in order to adopt a unified standard process, one of the listening methods can be selected and applied to all scenarios.

[0186] In addition, within a modification cycle or a scheduling cycle, only the same ICCH or the first command is allowed to appear. The advantage is that it avoids the complexity of processing by AIoT devices. After successfully decoding the ICCH or the inventory command within any repeated cycle and responding as needed, the device can go to sleep, avoiding repeated detection and monitoring.

[0187] It can be understood that a more flexible identification and validity marking method for the ICCH or the first command can also be designed. For example, version information or valid duration information, etc. can be carried in the ICCH or the first command. In these ways, the previous ICCH and the subsequent ICCH can be distinguished, facilitating more flexible inventory taking and avoiding delays between two inventory takings.

[0188] In a possible implementation manner of the embodiment of the present application, a solution for the ICCH configuration information or the first command to take effect across cells is further provided to improve the performance and efficiency of inventory taking. Specifically, in the embodiment of the present application, the problem of how to handle when an AIoT device reads an ICCH notification message or the first command in the ICCH in the source cell but cell reselection occurs is solved.

[0189] First, from the requirement level, the first command (taking the inventory command as an example) has the possibility and requirement to occur or take effect across cells.

[0190] It can be understood that without this enhanced performance of the ICCH configuration information or the first command taking effect across cells, according to the normal process, after the AIoT device moves to a new cell, the configurations and SIB messages of the old cell automatically become invalid, and the AIoT device needs to re-read the configurations and SIB content in the new cell and respond according to the requirements of the new cell. In this way, due to some AIoT devices being at the cell boundary or during cell replacement when inventory taking occurs, the inventory taking may be missed, resulting in missed detections or failures in the inventory taking by the network-side devices.

[0191] Therefore, in order to improve the success rate and efficiency of the AIoT device in executing the target service, the present application further optimizes the information carried in the SIB, thereby improving the success rate and efficiency of the AIoT device in executing the target service when it occurs or takes effect across cells.

[0192] Optionally, the SIB further includes area information, and the area information includes at least one of the following:

[0193] a) The first area corresponding to the SIB, and the first area is used to represent the effective area of the SIB.

[0194] b) The second area corresponding to the first command, and the second area is used to represent the effective area of the first command.

[0195] Scenario a: When the first terminal switches from the source cell to the target cell and the target cell is within the first area, the first terminal monitors the common control channel within the target cell based on the common control channel configuration information in the SIB obtained from the source cell.

[0196] For example, independent area information can be carried in SIB x, that is, the first area corresponding to SIB x, including: cell list, Tracking Area (TA) list information, etc., indicating that SIB x is common within the listed areas, characterizing that SIB x is valid within the listed areas.

[0197] Alternatively, when the first area corresponding to SIB x is the same as the first areas corresponding to other SIBs, the area information can be carried uniformly. For example, common cell list and TA list information are carried in SIB 1, and it is indicated in SIB1 that SIB x applies to this common area information. When the AIoT device obtains the above information and moves, if the newly reselected target cell belongs to the cells within the above area information, the AIoT device automatically defaults that the content in SIB x of the currently stored source cell is still valid in the target cell and can continue to be used. Furthermore, it can continue to read the ICCH, notification messages, or wake-up message IPEI, etc. in a similar manner to the source cell, reducing the impact of interruption.

[0198] Scenario b: When the first terminal switches from the source cell to the target cell and the target cell is within the second area, the first terminal executes the target service within the target cell based on the first command obtained from the source cell.

[0199] For example, an independent second area, such as cell list and TA list information, can be carried in SIB x to indicate that the first command corresponding to SIB x is common within the listed second areas, characterizing that the first command is valid within the listed areas.

[0200] When the AIoT device obtains the above information and moves, if the newly reselected target cell belongs to the cells within the above second area, the AIoT device automatically defaults that the first command received by the currently stored source cell but not responded to is still valid in the target cell and can continue to be responded to.

[0201] Alternatively, although the source cell has responded to the first command, since the response time point from the time of replacing the cell is within the configured or predetermined time range, such as 1 second, the response may fail to be received by the source cell. Therefore, after reselection to the target cell, the response is made to the target cell again.

[0202] Alternatively, after the source cell successfully responds to the first command, it reselects to the target cell. For the ICCH or the first command that is still repeating within the same modification period in the target cell, the ICCH or the first command with the same version number, and the ICCH or the first command whose effective duration is still valid, it can be determined as a repeated ICCH or first command and no longer respond to it here to avoid repeated interference in the response.

[0203] It should be noted that whether to avoid repetition is also determined according to the content of the target service. If the target service is inventory counting, repetition needs to be avoided, otherwise it will affect the overall statistics. However, if the content of the target service is to obtain the latest location or ownership of the AIoT device, then after the AIoT device switches to the target cell, it is still worth responding to the first command again to update its own location or ownership and ensure the reporting of the latest information.

[0204] Figure 4 It is the second flowchart of the data transmission method provided by the embodiments of the present application. As Figure 4 shown, the method includes step 401; where:

[0205] Step 401: The first device sends a first command to the first terminal; the first terminal is an Internet of Things AIoT device enabled by environmental energy, the first command is carried on a specific common control channel, and the first command is used to assist the first terminal in executing the target service.

[0206] It should be noted that the embodiments of the present application can be applied to the scenario where the first terminal (i.e., the AIoT device) executes the target service in the 3GPP technical framework. Among them, the target service can be an inventory service, a location or ownership reporting service, etc.

[0207] For example, when the target service is an inventory service, each AIoT device needs to respond to the first device when receiving the first command (also known as the inventory command) sent by the first device, so that the first device can determine the number of AIoTs.

[0208] For another example, when the target service is a location or ownership reporting service, each AIoT device needs to respond to the first device when receiving the first command sent by the first device, so that the first device can determine the latest location or ownership of each AIoT.

[0209] Optionally, the first device includes at least one of a network-side device and a second terminal; the second terminal is a terminal used to send the first command to the first terminal.

[0210] In the embodiment of the present application, the second terminal functions equivalently to the reader in RFID. Both the network-side device and the second terminal can send a first command to the AIoT device, so that the AIoT device responds to the first command and performs a target operation.

[0211] Among them, the first command is carried in a specific (also known as dedicated) CCCH. The specific CCCH is scheduled by a specific RNTI. Different types of AIoT devices or different types of target services can use different specific CCCHs. The AIoT device reads the first command of the corresponding specific CCCH to respond to the requirements of the network-side device or the second terminal.

[0212] The specific CCCH can be referred to as an ICCH. The network-side device or the second terminal can carry the first command in the ICCH and send it to the AIoT device.

[0213] In the data transmission method provided by the embodiment of the present application, the first device sends a first command to the AIoT device through a specific common control channel, so that the AIoT device can respond to the first command as needed and perform a target service, ensuring the success rate of the AIoT device receiving the first command, and further guaranteeing the feasibility and efficiency of the AIoT device in signaling transmission in the 3GPP technical framework, providing a feasible solution for the AIoT device to perform a target service in the 3GPP technical framework.

[0214] Optionally, the first device also needs to perform the following steps:

[0215] The first device sends common control channel configuration information to the first terminal.

[0216] Optionally, the common control channel configuration information includes at least one of the following:

[0217] a) The service type corresponding to the common control channel;

[0218] b) The type of the AIoT device corresponding to the common control channel;

[0219] c) A specific radio network temporary identifier RNTI, where the specific RNTI is used to schedule the common control channel;

[0220] d) The transmission period information of the common control channel;

[0221] e) The transmission parameters of the common control channel;

[0222] f) Information of a wake-up signal, where the wake-up signal is used to wake up the first terminal to monitor the common control channel.

[0223] Optionally, the transmission period information includes at least one of the following:

[0224] a) A scheduling period for the first device to schedule the common control channel within the scheduling period;

[0225] b) A scheduling window corresponding to the scheduling period for the first device to schedule the common control channel within the scheduling window;

[0226] c) At least one repetition period corresponding to the scheduling period for the first device to repeatedly schedule the common control channel within the repetition period;

[0227] d) A modification period for characterizing the range where the common control channel is allowed to change or become effective.

[0228] Optionally, the transmission parameters include at least one of the following:

[0229] a) Transmission bandwidth information;

[0230] b) Search space information;

[0231] c) Modulation and coding format.

[0232] Optionally, the information of the wake-up signal includes at least one of the following:

[0233] a) Whether the wake-up signal is supported;

[0234] b) The position of the wake-up signal.

[0235] Optionally, the common control channel configuration information is carried in the system information block SIB.

[0236] Optionally, the SIB further includes area information, and the area information includes at least one of the following:

[0237] a) A first area corresponding to the SIB, and the first area is used to characterize the effective area of the SIB;

[0238] b) A second area corresponding to the first command, and the second area is used to characterize the effective area of the first command.

[0239] Optionally, the first device further needs to perform the following steps:

[0240] The first device receives the first information reported by the first terminal; the first information is used to characterize that the first terminal cannot obtain the first command or the link fails.

[0241] The data transmission method provided by the embodiments of the present application may be executed by a data transmission device. In the embodiments of the present application, taking the data transmission device executing the data transmission method as an example, the data transmission device provided by the embodiments of the present application is described.

[0242] Figure 5 is one of the structural schematic diagrams of the data transmission device provided by the embodiments of the present application. As Figure 5 shown, the data transmission device 500 is applied to a first terminal and includes:

[0243] An acquisition module 501, configured to acquire a first command sent by a first device; the first terminal is an environment energy-enabled Internet of Things AIoT device, and the first command is carried in a specific common control channel, and the first command is used to assist the first terminal to execute a target service.

[0244] In the data transmission device provided by the embodiments of the present application, the first command sent by the first device is acquired through a specific common control channel, so that the AIoT device can respond to the first command on demand and execute the target service, ensuring the success rate of the AIoT device receiving the first command, and further guaranteeing the feasibility and efficiency of the AIoT device for signaling transmission in the 3GPP technical framework, and providing a feasible solution for the AIoT device to execute the target service in the 3GPP technical framework.

[0245] Optionally, the device further includes:

[0246] A first receiving module, configured to receive the common control channel configuration information sent by the first device.

[0247] Optionally, the common control channel configuration information includes at least one of the following:

[0248] The service type corresponding to the common control channel;

[0249] The type of the AIoT device corresponding to the common control channel;
