Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0130] With the rapid adoption of Internet of Things (IoT) technology across various industries, the large-scale deployment of IoT devices powered by traditional batteries is facing challenges, including environmental, cost, and energy conservation. This has led to limitations in some scenarios, hindering the demand and negatively impacting user experience. In some scenarios, the astronomical growth of IoT networks, coupled with the proliferation of IoT devices, has pushed network maintenance costs, including labor and battery costs, to new heights. Furthermore, billions of traditional batteries are discarded annually, with only a small fraction effectively recycled, negatively impacting the Earth's ecosystem. Maintaining IoT network operations and replacing batteries can be challenging in extreme environmental conditions. Battery-free IoT (also known as passive IoT) communications have been proposed to improve network performance and sustainability, expanding their application scenarios. Furthermore, battery-free communications are more environmentally friendly and safer for children and the elderly. By eliminating traditional batteries, device size and cost can be significantly reduced, paving the way for a variety of new applications.

[0131] In some embodiments, various low power wide area (LPWA) technologies, such as machine type communication (MTC), narrow band internet of things (NB-IoT), and reduced capability (RedCap) terminals, have been developed to meet the growing needs of vertical fields. These LPWA technologies achieve low cost, low power consumption, and large-scale connectivity, which can meet the requirements of many applications. However, there are still the following situations that need to be addressed: 1. In some scenarios (such as in extreme environmental conditions (e.g., high voltage, extremely high / low temperature, humid environment, etc.), devices powered by traditional batteries are not applicable. 2. Maintenance-free devices are required (e.g., devices that do not require replacement of traditional batteries). 3. Devices with ultra-low complexity, very small device size (e.g., millimeter (mm) thickness), and longer life cycle are required. In order to meet the above unmet needs, the Internet of Things that supports ambient energy is a very promising technology.

[0132] In some embodiments, an ambient-powered IoT device is one that is powered by harvested energy. This type of IoT device is battery-free or has limited energy storage capabilities (e.g., using capacitors). An ambient-powered IoT device can harvest radio waves, light, motion, heat, or any other suitable power source to power wireless communications or data transmission.

[0133] In some embodiments, the aforementioned ambient energy-enabled IoT devices may be interchangeable with terms such as passive devices, passive IoT devices, ambient energy-based devices, and ambient IoT devices.

[0134] In some embodiments, IoT devices that support ambient energy (such as ambient IoT devices) can use the energy collected from the environment to drive themselves for data transmission and wireless communication. The current mainstream low-power IoT communication chips (such as Bluetooth low energy (BLE) chips, long range radio (LoRa) chips, and NB-IoT chips) have a transmit and receive power consumption of tens of milliwatts or even hundreds of milliwatts, while the energy collected from the environment is only in the microwatt level, which is unable to drive devices with the above-mentioned types of chips to work. Therefore, a new wireless communication technology is needed to reduce communication power consumption to tens of microwatts or even less than ten microwatts. To this end, backscatter (BS) communication technology can be used. Backscatter communication is one of the key technologies for building a green, energy-saving, low-cost, and flexibly deployable future IoT, and is an important means to achieve "intelligent connection of all things."

[0135] In some embodiments, backscatter communication utilizes the principle of backscattering of radio frequency signals to design a modulation and transmission technology with extremely low power consumption. As shown in FIG1B , FIG1B is a schematic diagram of wireless communication based on backscattering according to an embodiment of the present disclosure. The excitation source 11 sends a radio frequency signal to the passive device 12. When the radio frequency signal reaches the passive device 12, a part of it will be reflected, and the passive device 12 can adjust the matching between the receiving antenna and the impedance according to the information to be sent to enhance the reflection of the above radio frequency signal, and modulate the information to be sent onto the backscattered signal for transmission. This process is similar to a reflector. Compared with other communication technologies, backscatter transmission does not require a complex radio frequency structure, reduces the use of devices such as power amplifiers, high-precision crystal oscillators, duplexers, high-precision filters, and does not require complex baseband processing. Therefore, it can simplify the design of the above-mentioned IoT devices that support environmental energy and greatly reduce the cost of equipment.

[0136] In some embodiments, the radio frequency signal is used to provide energy for the passive device to transmit a signal. Therefore, the radio frequency signal can be called an excitation signal or a trigger signal.

[0137] In some embodiments, the excitation source may be a reader of a passive device or an anchor point of a reader.

[0138] In some embodiments, when passive IoT technology is integrated into the communication system 100, the embodiments of the present disclosure may provide, but are not limited to, the following passive IoT system architectures:

[0139] Architecture 1: As shown in Figure 1C, which is a schematic diagram of an architecture of a passive IoT system according to an embodiment of the present disclosure, a passive device 12 and a network device 20 (such as an access network device) directly perform uplink and / or downlink transmission.

[0140] Architecture 2: As shown in Figure 1D, which is another schematic diagram of the architecture of a passive IoT system according to an embodiment of the present disclosure, uplink and / or downlink transmissions are indirectly performed between the passive device 12 and the network device 20 (such as an access network device) via an intermediate node 30.

[0141] In some embodiments, the intermediate node 30 forwards uplink transmission and / or downlink transmission. Exemplarily, the intermediate node 30 may be a relay node, an integrated access backhaul (IAB) node, a terminal, a signal amplification node (repeater), etc.

[0142] Architecture 3: As shown in Figure 1E, which is another schematic diagram of the architecture of a passive IoT system according to an embodiment of the present disclosure, passive device 12 and network device 20 (e.g., access network device) directly perform uplink or downlink transmission, and indirectly perform the other of the uplink and downlink transmissions through auxiliary node 40.

[0143] In some embodiments, the auxiliary node 40 forwards uplink transmission and / or downlink transmission. Exemplarily, the auxiliary node 40 may be a relay node, an integrated access backhaul (IAB) node, a terminal, a signal amplification node (repeater), etc.

[0144] Architecture 4: As shown in Figure 1F, Figure 1F is another schematic diagram of the architecture of a passive IoT system according to an embodiment of the present disclosure. Uplink and downlink transmissions are performed directly between the passive device 12 and the terminal 50. The terminal 50 is responsible for collecting data from the passive device 12 and forwarding the collected data to the network.

[0145] In some embodiments, when the passive Internet of Things system adopts the above-mentioned architecture one and architecture two for communication, the spectrum resources that can be used may include three deployment modes: in-band mode, guard-band mode, or stand alone mode. The in-band mode refers to the use of general uplink spectrum resources and / or downlink spectrum resources for transmission. The guard-band mode refers to the use of spectrum resources in the guard band between the general uplink spectrum and the downlink spectrum for transmission. The stand alone mode refers to the use of spectrum resources unrelated to the general transmission spectrum for transmission.

[0146] In some embodiments, the passive devices 12 may be classified into the following three types, but are not limited to:

[0147] Type A: No energy storage and no independent signal generation / amplification, and transmission is based on backscattering.

[0148] Type B: With energy storage but no independent signal generation, and transmission based on backscattering. The energy stored in the passive device 12 can be used to amplify the backscattered signal.

[0149] Type C: Has energy storage to enable independent signal generation and uses active RF components for transmission.

[0150] In some cases, to support data transmission from passive devices, a device in the network needs to support at least one of the following functions:

[0151] The function as an energy source (ES) is only applicable to type B and type C devices;

[0152] The downlink transmission (DT) function sends indication information to the passive device, thereby triggering the uplink transmission of the passive device. It is only used for type A devices.

[0153] This continuous wave (CW) function is only available to Type A and Type B devices. Type A devices transmit uplink signals by backscattering CW. CW is also a type of ES, and Type A devices can receive and store CW energy.

[0154] The uplink receiving (UR) function receives uplink information backscattered by passive devices or receives uplink information actively transmitted by passive devices. It is only used for type A devices.

[0155] It should be noted that the device that performs the above-mentioned ES, DT, CW, UR and other functions may be a terminal, a repeater, a relay node or a network device.

[0156] In some embodiments, a passive device may support only one of the above functions, or a passive device may support only multiple of the above functions, or a passive device may support only all of the above functions.

[0157] In the above-mentioned architecture 2, if the intermediate node (such as a terminal in the connected state (RRC_CONNECTED)) acts as a reader of the passive device, then if the intermediate node reports to the network side every time it receives data reported by a passive device, it will cause the intermediate node to frequently send uplink information on the air interface (such as the uu interface), occupying a large amount of air interface resources and increasing device power consumption.

[0158] In order to solve the above problems, the embodiments of the present disclosure provide an information transmission method, a communication apparatus, a communication device, and a storage medium to avoid frequently sending uplink information on the air interface, reduce the occupation of air interface resources, and reduce device power consumption.

[0159] In some embodiments, the first device may be the intermediate node 30 in the above-mentioned Architecture 2. In one example, the intermediate node may be a terminal in a connected state.

[0160] In some embodiments, the second device may be a passive device. In one example, the passive device may be an ambient IoT device.

[0161] In some embodiments, the terminal is an excitation source for the ambient IoT device.

[0162] As shown in Figure 2A, Figure 2A is an exemplary interaction diagram illustrating an information transmission method according to an embodiment of the present disclosure. This embodiment of the present disclosure relates to an information transmission method, which is performed by the above-mentioned passive Internet of Things system. The above-mentioned information transmission method includes steps S201 to S203.

[0163] In some embodiments, the passive IoT system may adopt Architecture 2 as shown in FIG. 1D .

[0164] In step S201, the terminal sends a first signal.

[0165] In some embodiments, the ambient IoT device receives a first signal.

[0166] In some embodiments, the first signal is an excitation signal or a trigger signal of the environmental Internet of Things device, which provides energy for the environmental Internet of Things device so that the environmental Internet of Things device sends uplink information in a backscattering manner.

[0167] In some embodiments, the terminal is a reader of an ambient IoT device or an anchor point for a reader.

[0168] In some embodiments, the terminal may be configured with a first function, where the first function may be a function for transmitting with an ambient IoT device. In some embodiments, the first function may be referred to as a reader function, a passive IoT function, an ambient IoT function, etc. In some embodiments, whether the terminal transmits with the ambient IoT device is configured by enabling or disabling the first function.

[0169] In one example, the terminal may be configured as a "reader," that is, enabled with a reader function. In another example, the terminal may be configured with an ambient IoT function, that is, enabled with an ambient IoT function.

[0170] In some embodiments, in order to report uplink information of the environmental Internet of Things device, the first function of the terminal is enabled. In this way, the terminal can transmit a first signal to collect the uplink information of the environmental Internet of Things device and report it to the network side.

[0171] In some embodiments, when the terminal enables the first function, the terminal can support receiving uplink information of the environmental Internet of Things device. In some embodiments, the terminal has the ability to support receiving uplink information of the environmental Internet of Things device.

[0172] In some embodiments, the terminal may further support at least one of the following: receiving a backscattered signal sent by an environmental Internet of Things device, sending downlink information for instructing the environmental Internet of Things device to perform a first operation, the environmental Internet of Things device sending a continuous wave (CW) for carrying uplink information, and sending a power supply signal for the function of the environmental Internet of Things device.

[0173] In some embodiments, the terminal may also have at least one of the following capabilities: supporting reception of backscattered signals sent by environmental Internet of Things devices, supporting sending downlink information for instructing the environmental Internet of Things devices to perform a first operation, supporting the environmental Internet of Things devices to send continuous waves (CW) for carrying uplink information, and supporting sending power signals for environmental Internet of Things device functions.

[0174] In some embodiments, the first signal may also carry downlink information. This downlink information is used to instruct the ambient IoT device to perform a first operation. In this case, the downlink information may be downlink signaling. In one example, the first operation may be instructing the ambient IoT device to shut down, start up, restart, or send the first uplink information, etc., which is not specifically limited in the present embodiments.

[0175] In some embodiments, after being coupled to the first signal, the environmental Internet of Things device can modulate its own uplink information (ie, the first uplink information) onto the backscattered first signal (ie, the second signal) and send it to the terminal.

[0176] In step S202, the environmental Internet of Things device sends first uplink information.

[0177] In some embodiments, the terminal receives first uplink information.

[0178] In some embodiments, the first uplink information may include uplink signaling of the environmental Internet of Things device, and may also include data perceived by the environmental Internet of Things device. Of course, it may also include information sent to the network by other environmental Internet of Things devices. The embodiments of the present disclosure do not specifically limit this.

[0179] In some embodiments, the second signal may be a backscattered signal sent by the ambient IoT device in response to the excitation signal. In some embodiments, the backscattered signal may be modulated with uplink information (i.e., first uplink information) of the ambient physical network device.

[0180] In some embodiments, the ambient IoT device may be the aforementioned type A device and / or type B device.

[0181] In some embodiments, after receiving the first uplink information, the terminal stores the first uplink information to obtain the second uplink information.

[0182] In some embodiments, the terminal receives the first uplink information while monitoring a preset event. When the preset event is triggered, the terminal executes step S203.

[0183] In step S203, when a preset event is triggered, the terminal sends second uplink information.

[0184] In some embodiments, the network device receives second uplink information.

[0185] In some embodiments, the second uplink information is the first uplink information received by the terminal before the preset event is triggered. In this case, the second uplink information may include one or more first uplink information.

[0186] In some embodiments, the terminal may collect first uplink information from one or more ambient IoT devices and store the first uplink information. Upon detecting that a preset event is triggered, the terminal may report the stored one or more first uplink information (i.e., second uplink information) to the network device.

[0187] In some embodiments, the second uplink information can be carried in RRC signaling dedicated to reporting uplink information of the environmental Internet of Things, or can be carried in any RRC signaling that sends uplink information. The embodiments of the present disclosure do not specifically limit this.

[0188] In some embodiments, the preset event may include, but is not limited to, at least one of the following events 1 to 5:

[0189] Event 1: The cumulative size of the first uplink information received by the terminal reaches a first threshold.

[0190] Event 2: The cumulative number of environmental IoT devices that send the first uplink information to the terminal reaches the second threshold.

[0191] Event three: the first timer times out. The first timer is started when the terminal receives the first uplink information for the first time.

[0192] Event 4: the second timer times out. The second timer is started each time the terminal receives the first uplink information.

[0193] Event 5: The terminal receives a first message from the network device, where the first message is used to request the terminal to send uplink information from the environmental IoT device.

[0194] The following describes step S203 for each preset event.

[0195] In some embodiments, as shown in FIG2B , which is an exemplary interaction diagram of an information transmission method according to an embodiment of the present disclosure, when the preset event is event 1, the above step S203 can be replaced by steps S2101 to S2103 .

[0196] In step S2101, the terminal accumulates the size of the first uplink information received each time.

[0197] In some embodiments, the size of the first uplink information can be understood as the data volume, data size, information volume, etc. In one example, the size of the first uplink information can be accumulated in bytes.

[0198] In step S2102, when the accumulated size of the first uplink information reaches a first threshold, the terminal sends the second uplink information.

[0199] In some embodiments, the network device receives second uplink information.

[0200] In some embodiments, the first threshold value may be pre-configured, configured by a network device, or determined by the terminal based on its own implementation, capabilities, etc., which is not specifically limited in the embodiments of the present disclosure. In one example, the first threshold value may be configured based on factors such as the amount of storage space in the terminal, the remaining battery power of the terminal, and the latency requirements of the service.

[0201] In some embodiments, to balance the timeliness of uplink information reporting by environmental IoT devices and the power consumption of the terminal, different first thresholds can be set for services with different latency requirements. For example, for services with higher latency requirements, the first threshold can be set to a smaller value to ensure timely reporting of the first uplink information. For services with lower latency requirements, the first threshold can be set to a larger value (such as the maximum value of the terminal's storage space) to reduce the number of times the first uplink information is sent and reduce the power consumption of the terminal.

[0202] In steps S2101 to S2102, each time the terminal receives the first uplink information sent by the environmental Internet of Things device through the backscatter signal, the terminal accumulates the size of all received first uplink information, and when the accumulated size of the first uplink information is greater than or equal to the first threshold, the terminal sends all received first uplink information (i.e., second uplink information) to the network device.

[0203] In some embodiments, after step S2101, when the accumulated size of the first uplink information reaches a first threshold, the terminal may further execute step S2103.

[0204] In step S2103, the size of the first uplink information is cleared to 0. In this way, after receiving the first uplink information next time, the terminal starts to accumulate the size of the first uplink information again until event 1 is triggered.

[0205] In one example, after receiving the first uplink information from the ambient IoT device, the terminal in RRC_CONNECTED accumulates the information size variable (TagData) of the first uplink information, where TagData = TagData + tag data size. If TagData ≥ TagDataByte, the terminal reports the received first uplink information to the network device and sets TagData = 0. TagData represents the size of the first uplink information received by the terminal, tag data size represents the size of the first uplink data newly received by the terminal, and TagDataByte represents the first threshold.

[0206] In some embodiments, as shown in FIG2C , which is an exemplary interaction diagram of an information transmission method according to an embodiment of the present disclosure, when the preset event is event 2, the above step S203 can be replaced by steps S2201 to S2203 .

[0207] In step S2201, the terminal accumulates the number of environmental Internet of Things devices that send the first uplink information each time.

[0208] In some embodiments, each time the terminal receives the first uplink information, the terminal accumulates the number of environmental Internet of Things devices that sent the first uplink information. In one example, the terminal can set a counter to achieve the accumulation of the number of environmental Internet of Things devices.

[0209] In step S2202, when the accumulated number of environmental IoT devices reaches a second threshold, the terminal sends second uplink information.

[0210] In some embodiments, the network device receives second uplink information.

[0211] In some embodiments, the second threshold value may be pre-configured, configured by a network device, or determined by the terminal based on its own implementation, capabilities, etc., which is not specifically limited in the embodiments of the present disclosure. In one example, the second threshold value may be configured based on factors such as the amount of storage space in the terminal, the remaining battery power of the terminal, and the latency requirements of the service.

[0212] In some embodiments, to balance the timeliness of uplink information reporting by environmental IoT devices and the power consumption of the terminal, different second thresholds can be set for services with different latency requirements. For example, for services with higher latency requirements, the second threshold can be set to a smaller value to ensure timely reporting of the first uplink information. For services with lower latency requirements, the second threshold can be set to a larger value (such as the maximum value of the terminal's storage space) to reduce the number of times the first uplink information is sent and reduce the power consumption of the terminal.

[0213] In steps S2201 to S2202, the terminal accumulates the number of environmental Internet of Things devices each time after receiving the first uplink information sent by the environmental Internet of Things device through the backscatter signal, and when the accumulated number of environmental Internet of Things devices is greater than or equal to the second threshold, the terminal sends the first uplink information (i.e., the second uplink information) sent by these environmental Internet of Things devices to the network device.

[0214] In some embodiments, after step S2201, when the accumulated number of environmental IoT devices reaches a second threshold, the terminal may further execute step S2203.

[0215] In step S2203, the number of environmental Internet of Things devices is reset to zero. In this way, after the terminal receives the first uplink information next time, it starts to accumulate the number of environmental Internet of Things devices again until event 2 is triggered.

[0216] In one example, after receiving the first uplink information from an ambient IoT device, a terminal in RRC_CONNECTED accumulates the variable (TagNumber) for the number of ambient IoT devices. At this time, TagNumber = TagNumber + 1. If TagNumber ≥ TagNumberThreshold, the terminal reports the received first uplink information to the network device and sets TagNumber = 0. TagNumber is the number of ambient IoT devices that have sent the first uplink information to the terminal, and TagNumberThreshold is the second threshold.

[0217] In some embodiments, as shown in FIG2D , which is an exemplary interaction diagram of an information transmission method according to an embodiment of the present disclosure, when the preset event is event three, the above step S203 can be replaced by step S2301 .

[0218] In step S2301, when the first timer times out, the terminal sends second uplink information.

[0219] In some embodiments, the network device receives second uplink information.

[0220] In some embodiments, the second uplink information includes the first uplink information received by the terminal during the running of the first timer. In this case, the second uplink information may include one or more first uplink information.

[0221] In some embodiments, the first timer may be started when the terminal receives the first uplink information for the first time.

[0222] In some embodiments, the first timer can be pre-configured, configured by a network device, or determined by the terminal based on its own implementation, capabilities, etc., which is not specifically limited in the embodiments of the present disclosure. In one example, the duration of the first timer can be configured based on factors such as the amount of storage space in the terminal, the remaining power of the terminal, and the latency requirements of the service.

[0223] In some embodiments, the terminal starts a first timer when it first receives the first uplink information, and receives the first uplink information sent by the ambient IoT device during the first timer. When the first timer expires, the terminal sends the first uplink information received during the first timer (i.e., the second uplink information) to the network device.

[0224] In some embodiments, after the first timer times out, the terminal may further perform one of the following steps: starting the first timer and restarting the first timer when receiving the first uplink information for the first time.

[0225] In some embodiments, after the first timer times out, the terminal may start the first timer when the first uplink information is received for the first time, and the first uplink information received during the operation of the first timer, and return to the above step S2303 until the first timer times out again, and the terminal sends the first uplink information received during the operation of the first timer to the network device.

[0226] In some embodiments, after the first timer times out, the terminal may restart the first timer, and receive the first uplink information during the operation of the first timer, and return to the above step S2301 until the first timer times out again, and the terminal sends the first uplink information received during the operation of the first timer to the network device.

[0227] In some embodiments, if the terminal does not receive the first uplink information during the running of the first timer, the terminal may immediately restart the first timer when the first timer times out and continue to collect the first uplink information.

[0228] In one example, when a terminal in RRC_CONNECTED receives the first first uplink information, it starts a first timer (referred to as timer T1). When timer T1 expires, the terminal reports all first uplink information received during the timer T1 period to the network device, and restarts timer T1 when the first first uplink information is received.

[0229] In one example, when a terminal in RRC_CONNECTED receives the first first uplink information, it starts a first timer (referred to as timer T1). When timer T1 times out, the terminal reports all first uplink information received during the timer T1 to the network device and restarts timer T1.

[0230] In some embodiments, as shown in FIG2E , which is an exemplary interaction diagram of an information transmission method according to an embodiment of the present disclosure, when the preset event is event four, the above step S203 can be replaced by step S2401 .

[0231] In step S2401, when the second timer times out, the terminal sends second uplink information.

[0232] In some embodiments, the network device receives second uplink information.

[0233] In some embodiments, the second uplink information includes the first uplink information received by the terminal during the running of the second timer. In this case, the second uplink information may include one or more first uplink information.

[0234] In some embodiments, the second timer may be started each time the terminal receives the first uplink information.

[0235] In some embodiments, the second timer can be pre-configured, configured by a network device, or determined by the terminal based on its own implementation, capabilities, etc., which is not specifically limited in the embodiments of the present disclosure. In one example, the duration of the second timer can be configured based on factors such as the amount of storage space in the terminal, the remaining power of the terminal, and the latency requirements of the service.

[0236] In some embodiments, the terminal starts the second timer each time it receives the first uplink information, and receives the first uplink information sent by the environmental Internet of Things device during the operation of the second timer. In some cases, the environmental Internet of Things device frequently sends the first uplink information to the terminal. At this time, before the second timer times out, the terminal can restart the second timer due to the receipt of new first uplink information, and repeat this process until the second timer times out. At this time, it means that the environmental Internet of Things device has temporarily not sent the first uplink information to the terminal. Then, when the second timer times out, the terminal can send the first uplink information received during the operation of the second timer (i.e., the second uplink information) to the network device.

[0237] In some embodiments, after the second timer times out, the terminal may further perform one of the following steps: starting the second timer and restarting the second timer when receiving the first uplink information for the first time.

[0238] In some embodiments, after the second timer times out, the terminal may start the second timer when the first uplink information is received for the first time, and receive the first uplink information during the operation of the second timer, and return to the above step S2401 until the second timer times out again, and the terminal sends the first uplink information received during the operation of the second timer to the network device.

[0239] In some embodiments, after the second timer times out, the terminal may restart the second timer, and receive the first uplink information during the operation of the second timer, and return to the above step S2401 until the second timer times out again, and the terminal sends the first uplink information received during the operation of the second timer to the network device.

[0240] In some embodiments, if the terminal does not receive the first uplink information during the running of the first timer, the terminal may immediately restart the first timer when the first timer times out and continue to collect the first uplink information.

[0241] In one example, a terminal in RRC_CONNECTED starts a second timer (referred to as timer T2) each time it receives first uplink information. When timer T2 expires, the terminal reports all first uplink information received during the timer T2 period to the network device, and restarts timer T2 upon receiving the first first uplink information.

[0242] In one example, the terminal in RRC_CONNECTED starts a second timer (referred to as timer T2) each time it receives first uplink information. When timer T2 expires, the terminal reports all first uplink information received during the timer T2 to the network device and restarts timer T2.

[0243] In some embodiments, as shown in FIG2F , which is an exemplary interaction diagram of an information transmission method according to an embodiment of the present disclosure, when the preset event is event five, the above step S203 can be replaced by steps S2501 to S2503 .

[0244] In step S2501, the terminal sends first information.

[0245] In some embodiments, a network device receives first information.

[0246] In some embodiments, the first information is used to indicate at least one of the following: the presence of first uplink information to be reported in the terminal and the size of the first uplink information to be reported. In some embodiments, the first information is used to indicate the presence of first uplink information to be reported in the terminal (i.e., second uplink information). In some embodiments, the first information is used to indicate whether the first uplink information to be reported exists in the terminal, wherein when the first information is a first value, it may indicate that the first uplink information to be reported exists in the terminal, and when the first information is a second value, it may indicate that the first uplink information to be reported does not exist in the terminal. In some embodiments, the first information is used to indicate the size of the first uplink information to be reported in the terminal. In some embodiments, the first information may include two fields, one field for indicating the presence of the first uplink information to be reported in the terminal, and the other field for indicating the size of the first uplink information to be reported.

[0247] In some embodiments, the first information is carried in uplink signaling. In one example, the uplink signaling can be media access control-control element (MAC-CE) signaling or RRC signaling. In some embodiments, the first information can be carried in RRC signaling dedicated to reporting uplink information of the environmental Internet of Things, or can be carried in any RRC signaling that sends uplink information, which is not specifically limited in the embodiments of the present disclosure.

[0248] In some embodiments, the terminal may determine whether to send the first information to the network device based on its own implementation, capabilities, etc. In one example, the timing of sending the first information may be determined based on factors such as the storage space size of the terminal, the remaining power of the terminal, and the latency requirements of the service.

[0249] In step S2502, the network device sends a first message.

[0250] In some embodiments, the terminal receives a first message.

[0251] In some embodiments, the first message is used to request the terminal to send uplink information of the environmental Internet of Things device.

[0252] In some embodiments, after receiving the first information, the network device sends a first message to the terminal according to the first information to request the terminal to report the first uplink information.

[0253] In some embodiments, the first message may be downlink signaling. In one example, the downlink signaling may be MAC-CE signaling, RRC signaling, or downlink control information (DCI) signaling. In some embodiments, the first message may be carried in RRC signaling dedicated to reporting uplink information of the environmental IoT, or in any RRC signaling that transmits uplink information, which is not specifically limited in the embodiments of the present disclosure.

[0254] In some embodiments, step S2501 can be omitted. In the case where step S2501 is omitted, the network device can trigger the sending of the first message by itself to request the terminal to send uplink information of the environmental Internet of Things device.

[0255] In step S2503, the terminal sends second uplink information according to the first message.

[0256] In some embodiments, the network device receives second uplink information.

[0257] In some embodiments, the second uplink information may include first uplink information received by the terminal before receiving the first message.

[0258] In some embodiments, the preset event may further include a combination of event 1 to event 5. Then, when all events included in the preset event are triggered, the terminal sends the second uplink information.

[0259] In one example, the preset event may include a combination of event 1 and event 3. Then, when the cumulative size of the first uplink information received by the terminal reaches a first threshold and the first timer times out, the terminal sends the second uplink information.

[0260] In one example, the preset event may include a combination of event 1 and event 4. Then, when the cumulative size of the first uplink information received by the terminal reaches a first threshold and the second timer times out, the terminal sends the second uplink information.

[0261] In one example, the preset event may include a combination of event 1 and event 3. Then, when the cumulative number of environmental IoT devices that send the first uplink information to the terminal reaches a second threshold and the first timer times out, the terminal sends the second uplink information.

[0262] In one example, the preset event may include a combination of event 1 and event 4. Then, when the cumulative number of environmental IoT devices that send the first uplink information to the terminal reaches a second threshold and the second timer times out, the terminal sends the second uplink information.

[0263] In some embodiments, different priorities may be set for the events 1 to 5. When the preset event includes at least one of events 1 to 5, the terminal may send the second uplink information according to the priority of the event when the event is triggered.

[0264] In one example, the preset events may include a combination of event 1, event 3, and event 5, where event 5 has the highest priority and event 1 has the lowest priority. Therefore, if event 5 is triggered before the first timer expires, the terminal sends the second uplink information. Alternatively, if event 1 is triggered before the first timer expires, the terminal continues to collect the first uplink information until event 3 is triggered, at which point the terminal sends the second uplink information.

[0265] It should be noted that the above embodiments are only some examples of preset events. Preset events may also exist in other situations, and the embodiments of the present disclosure do not specifically limit this.

[0266] The information transmission method involved in the embodiments of the present disclosure may include at least one of steps S201 to S203, steps S2101 to S2103, steps S2201 to S2203, step S2301, step S2401, and steps S2501 to S2503.

[0371] In some embodiments, the above method may include the method described in the above embodiments on the passive Internet of Things system side and the network device side, which will not be repeated here.

[0372] In some embodiments, embodiments of the present disclosure further provide an information transmission method. In some embodiments, for a terminal in a connected state (such as an RRC_CONNECTED UE), the network side is configured as a reader or configured to implement an ambient IoT function. For example, the terminal supports at least one of ambient IoT data reception (must be supported), backscatter (BS) reception, downlink (DL) signaling signal transmission, continuous wave (CW) transmission, and power signal transmission.

[0373] In some embodiments, the information transmission method may include, but is not limited to, at least one of the following solutions 1 to 5:

[0374] Option 1:

[0375] RRC_CONNECTED UE receives data from a tag (or ambient IOT device) (i.e., first uplink information), then the tag data size variable TagData = TagData + tag data size. If TagData ≥ TagDataByte (first threshold), the UE is triggered to report the collected tag data (i.e., second uplink information) through RRC signaling, and TagData = 0 is set. TagDataByte is a threshold configured on the network side. The amount of data can be calculated in bytes.

[0376] Option 2:

[0377] When an RRC_CONNECTED UE receives tag (or ambient IoT device) data (i.e., first uplink information), the tag number variable TagNumber = TagNumber + 1. If TagNumber ≥ TagNumberThreshold (second threshold), the UE is triggered to report the collected tag data (i.e., second uplink information) via RRC signaling and set TagNumber = 0. TagNumberThreshold is a threshold configured on the network side.

[0378] Option 3:

[0379] When the RRC_CONNECTED UE receives the data reported by the first tag (ie, the first uplink information), it starts timer T1 (ie, the first timer).

[0380] In some embodiments, if timer T1 times out, the UE is triggered to report the collected tag data (ie, the second uplink information) via RRC signaling and restart timer T1. The size of timer T1 is configured by the network side.

[0381] Option 4:

[0382] Each time an RRC_CONNECTED UE receives tag data (i.e., first uplink information) from a tag (or ambient IoT device), it starts or restarts timer T2. If timer T2 expires, the UE is triggered to report the collected tag data (i.e., second uplink information) via RRC signaling and restart timer T2. The length of timer T2 is configured by the network.

[0383] In some embodiments, if no new data is received within the preset T2, the terminal may consider that there is no new data temporarily. At this time, the terminal may report the previously collected tag data (ie, the second uplink information) through RRC signaling.

[0384] Option 5:

[0385] RRC_CONNECTED The UE receives the request information from the network side, which triggers the UE to report the collected tag data (ie, the first uplink information) through RRC signaling. In some embodiments, the request information can be carried in RRC signaling, MAC CE or DCI.

[0386] In some embodiments, the UE may indicate to the network the size of the stored tag data or the presence of the tag data. In some embodiments, the above-mentioned indication information may be carried in a MAC CE or RRC signaling. Here, the RRC signaling may be any uplink signaling, or may be an uplink signaling reporting the tag data.
