In this case, the interfaces between or within the access network devices involved in the embodiments of the present disclosure can be transformed into internal interfaces of Open RAN, and the processes and information interactions between these internal interfaces can be implemented through software or programs.

Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution proposed in the embodiment of the present disclosure is also applicable to similar technical problems.

[0174] The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG1A , or a portion thereof, but are not limited thereto. The entities shown in FIG1A are examples. The communication system may include all or part of the entities shown in FIG1A , or may include other entities outside of FIG1A . The number and form of the entities are arbitrary. The entities may be physical or virtual. The connection relationship between the entities is an example. The entities may be connected or disconnected. The connection may be in any manner, whether direct or indirect, and may be wired or wireless.

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

[0176] In some embodiments of the present disclosure, A-IoT is a new Internet of Things technology. Compared with traditional Internet of Things technology, a notable feature is that the number of A-IoT terminals (A-IoT UE, A-IoT device, A-IoT Tag) that can be connected to the network is huge, and they have a simple structure, low hardware and maintenance costs, low power consumption, and can be used for a long time without replacing batteries.

[0177] A-IoT can be used for large-scale inventory management, where A-IoT devices report Electronic Product Codes (EPCs) to the network / intermediary node X / UE. This can be applied to sensing scenarios such as smart homes and environmental monitoring, where data is reported when certain trigger conditions are met. This can be used in positioning scenarios to find items or locate objects within a mall. It can also be used in command scenarios to respond to commands sent by network devices.

[0178] Ambient-IoT devices can include the following types:

[0179] (1) 1 microwatt peak power consumption, energy storage function, initial sampling frequency offset (SFO) up to 10X ppm, no downlink amplifier or uplink amplifier in the device, the uplink transmission of the device is reflected on the externally provided carrier.

[0180] (2) Peak power consumption ≤ several hundred microwatts, energy storage capability, SFO up to 10X ppm, and in-device downlink (DL) and / or uplink (UL) amplifiers. The uplink transmission of the device can be generated internally or reflected on an externally provided carrier.

[0181] Device 1: has a peak power consumption of 1 uW, has energy storage, and cannot perform independent signal generation / amplification. For example, it uses backscattering and does not have the ability to amplify DL and / or UL signals.

[0182] Device 2a: has a peak power consumption of several hundred uW and has energy storage capability. It cannot generate signals independently and uses backscattering. The stored energy can be used for DL ​​and / or UL signal amplification.

[0183] Device 2b: has a peak power consumption of several hundred uW, has energy storage capabilities, and can independently generate signals, such as a radio frequency (RF) module that actively transmits signals.

[0184] Device2c: It has the ability to actively transmit information and backscatter.

[0185] In addition, since Device 1 and Device 2a can only use the backscattering mode and cannot actively send signals, when they need to send information, they must be provided with electromagnetic waves (Continuous Wave, CW) for backscattering by the outside world. The coverage range supported by these terminals is relatively small, but the power consumption of the working mode of Device A / B is much lower than that of Device C.

[0186] Backscattering is the underlying mechanism. For devices using backscattering, while transmitting data, they require an energy source (CW node) that provides continuous electromagnetic waves (CW) for reflection. CW waves typically have a constant amplitude. The CW node can be a single node or a network or intermediate node (such as a user equipment terminal) communicating with the device. The A-IoT device reflects the received CW waves, attaches the signaling / data to the reflected waves, and transmits them. The reflected waves and CW waves have the same frequency or a certain frequency offset. The CW waves also power the A-IoT device. Device 1 receives the CW wireless signal, activates its internal receive processing module, and begins encoding and modulating the signaling / data to be uploaded by the A-IoT device.

[0187] A-IoT network devices include networks, terminals, intermediate nodes, auxiliary nodes, etc. Intermediate nodes can be relays, integrated access and backhauling (IAB) nodes, UEs, and repeaters.

[0188] In some embodiments, FIG1B is a schematic diagram illustrating a data transmission according to an embodiment of the present disclosure. As shown in FIG1B , the A-IoT device supports the following two deployment structures:

[0189] (1): Direct DL and UL data reception and transmission between ambient IoT devices and the network;

[0190] (2): The DL and UL data reception and transmission between the environmental IoT devices and the network are carried out indirectly through the intermediate nodes, and there are intermediate nodes in the middle for forwarding. For example, the intermediate nodes can be relays, IABs, UEs, and repeaters.

[0191] In some embodiments, in a passive IoT system, data transmission by a terminal includes the following three types:

[0192] (1) Reporting data based on network demand, such as inventory counts.

[0193] (2) Based on environmental IoT triggers, for example, the temperature of the sensor is higher than the configured threshold.

[0194] (3) Periodic data reporting, which is a regular request from the network to achieve regular environmental IoT data reporting; or based on the environmental IoT self-triggering, to achieve periodic environmental IoT data reporting (difficult to achieve due to discontinuous power supply and timing difficulties).

[0195] In some embodiments, device1 and device2a need to collect RF energy through the RF energy collection module to charge the devices, and store energy through the energy storage module. Only when the devices are powered can they activate the internal receiving module to receive and demodulate downlink signals, or activate the uplink transmitting module to encode, modulate, and transmit the signaling / data to be uploaded by the A-IoT device. These processes require a powered state. Therefore, when there is no power or a partial charge, and there is a need to transmit or receive uplink or downlink signals, the UE's behavior needs to be further specified.

[0323] In some embodiments, the second condition may include: the first time is before the second time, the first time is the time when it is determined that the downlink signal needs to be received, and the second time is the time when it is determined that the uplink signal needs to be sent.

[0324] In some embodiments, the second condition can be understood as that after the terminal device reaches a fully charged state, an uplink signal is sent. When a downlink signal is to be received, the terminal device is out of power or the remaining energy is insufficient to receive a downlink signal. For the convenience of description, the unreceived downlink signal can be represented as a first downlink signal, and the time required to receive the first downlink signal is the first time. In this case, the terminal device can first collect energy, and after collecting enough energy, it can first receive the first downlink signal. After receiving the first downlink signal, there is an uplink signal to be sent, and the time required to send the uplink signal is the second time. However, at this time, the remaining energy is insufficient to send the uplink signal, and the sending of the uplink signal is abandoned.

[0325] In some embodiments, determining that the first operation includes giving up sending the uplink signal and collecting energy; determining that the terminal device has reached the fully charged state and the uplink signal meets the first condition, and sending the uplink signal, the first condition includes at least one of the following: there is no signal to be sent at the current moment, and the waiting time of the uplink signal is less than the second time threshold.

[0326] In some embodiments, the second condition is used to indicate that the terminal device can send uplink signals but cannot receive downlink signals;

[0328] Determining that the terminal device meets the second condition and needs to send the uplink signal, the first operation includes sending the uplink signal and collecting energy; or,

[0329] It is determined that the terminal device meets the second condition and needs to send the uplink signal, and the first operation is to send the uplink signal.

[0330] In some embodiments, the second condition may include:

[0331] The first energy of the terminal device at the current moment is greater than or equal to the fourth energy threshold and less than the fifth energy threshold. The fourth energy threshold is the energy required for the terminal device to send the uplink signal, and the fifth energy threshold is the energy required for the terminal device to receive the downlink signal. The fourth energy threshold is less than the fifth energy threshold, and the fifth energy threshold is less than the first energy threshold. The first energy threshold is the energy when the terminal device is in the fully charged state.

[0332] In some embodiments, the definition and configuration of the fourth energy threshold and the fifth energy threshold may refer to the first energy threshold, and will not be repeated here.

[0333] In some embodiments, the second condition can be understood as the energy required by the terminal device to send an uplink signal being less than the energy required to receive a downlink signal.

[0334] In some embodiments, the terminal device meeting the second condition can be understood as the first energy of the terminal device at the current moment can be used to send an uplink signal once, but is insufficient to receive a downlink signal once.

[0335] In some embodiments, if the terminal device meets the second condition, then when there is an uplink signal to be sent, the terminal device may transmit the uplink signal and simultaneously perform energy collection, or it may not perform energy collection. If energy collection is not performed, the terminal device may perform energy collection after the uplink signal is transmitted. When there is a downlink signal to be received, the terminal device may abandon the reception of the downlink signal and only perform energy collection.

[0336] In some embodiments, the second condition includes:

[0337] The third time is before the fourth time. The third time is the time when it is determined that the uplink signal needs to be sent, and the fourth time is the time when it is determined that the downlink signal needs to be received.

[0338] In some embodiments, the second condition can be understood as, after the terminal device reaches a fully charged state, it receives a downlink signal. When it is about to send an uplink signal, the terminal device is out of power or the remaining energy is not enough to send an uplink signal. For the convenience of description, the unsent uplink signal can be represented as the first uplink signal, and the time required to send the first uplink signal is the third time. In this case, the terminal device can first collect energy, and after collecting enough energy, it can first send the first uplink signal. After sending the first uplink signal, there is a downlink signal to be received. The time required to receive the downlink signal is the fourth time, but at this time the remaining energy is not enough to receive the downlink signal, and the downlink signal is abandoned.

[0339] In some embodiments, it is determined that the terminal device is in the fully charged state and needs to receive the downlink signal, and the first operation is to receive the downlink signal; or, it is determined that the terminal device is in the fully charged state and needs to send the uplink signal, and the first operation is to send the uplink signal.

[0340] In some embodiments, if the energy collected by the terminal device is equal to a first energy threshold, or the duration of energy collection is greater than or equal to the first duration threshold, it can be determined that the terminal device is in a fully charged state. When the terminal device is in a fully charged state, it can enter a downlink signal receiving state or an uplink signal sending state. When downlink signal reception is required, the downlink signal is received, and when uplink signal transmission is required, the uplink signal is transmitted.

[0341] In some embodiments, it is determined that the terminal device does not need to send the uplink signal and does not need to receive the downlink signal; and the terminal device is controlled to enter the sleep state.

[0342] In some embodiments, the "sleep state" may also be referred to as the "hibernation state" or the "light sleep state", which is not limited in the embodiments of the present disclosure.

[0343] In some embodiments, if the terminal device is in a fully charged state and does not need to send an uplink signal or receive a downlink signal, the terminal device can be controlled to enter a sleep state.

[0344] In some embodiments, the network device may send a charging signal to the terminal device, and the terminal device may collect energy through the charging signal.

[0345] In some embodiments, the charging signal can be sent by a node device within the topology structure, such as a base station or an intermediate node UE. The charging signal can also be a downlink signal or a specific signal dedicated to charging the terminal device. The charging signal can also be a specific signal dedicated to charging the terminal device sent by a node device outside the topology structure.

[0346] In some embodiments, if the first operation performed by the terminal device is sending an uplink signal, the second operation performed by the network device is receiving an uplink signal; if the first operation performed by the terminal device is receiving a downlink signal, the second operation performed by the network device is sending a downlink signal; if the first operation performed by the terminal device is collecting energy, the second operation performed by the network device is sending a charging signal.

[0347] It should be noted that the embodiment of the present disclosure does not limit the order in which the terminal device performs the first operation and the network device performs the second operation.

[0348] By adopting the above method, the terminal device can perform different operations in a fully charged state or a partially charged state, thereby improving system performance.

[0349] The method involved in the embodiment of the present disclosure may include at least one of the above steps S3101 and S3102. For example, step S3101 can be implemented as an independent embodiment, step S3102 can be implemented as an independent embodiment, and steps S3101+S3102 can be implemented as independent embodiments.

[0350] FIG4 is a flow chart of a communication method according to an embodiment of the present disclosure. As shown in FIG4 , the embodiment of the present disclosure relates to a communication method, which can be executed by a network device. The method may include:

[0351] Step S4101: Execute the second operation.

[0352] The optional implementation of step S4101 can refer to the optional implementation of step S2102 in Figure 2 and other related parts in the embodiment involved in Figure 2, which will not be repeated here.

[0353] In some embodiments, the second operation may include at least one of the following:

[0354] Send downlink signal;

[0355] Receive uplink signals;

[0356] Send a charging signal, which is used by the terminal device to collect energy.

[0357] In some embodiments, the second operation may be performed when the terminal device determines whether it is in a fully charged state and performs the first operation in a fully charged state or an uncharged state.

[0358] For example, if the terminal device is determined to be in a fully powered state and the first operation performed is to send an uplink signal, the network device can receive the uplink signal sent by the terminal device; if the network device sends a downlink signal, the terminal device is determined to be in a fully powered state and is determined to be able to perform the first operation of receiving a downlink signal, then the terminal device can receive the downlink signal sent by the network device.

[0359] For another example, if the network device sends a charging signal, the terminal device determines that it is not in a fully charged state, and determines that the first operation to be performed is to collect energy, then the terminal device can collect energy through the charging signal sent by the network device; if the network device sends a charging signal and also sends a downlink signal, the terminal device determines that it is not in a fully charged state, and determines that the first operation to be performed is to receive the downlink signal and collect energy, then the terminal device can receive the downlink signal sent by the network device, and collect energy through the charging signal sent by the network device; if the network device sends a charging signal, the terminal device determines that it is not in a fully charged state, and determines that the first operation to be performed is to send an uplink signal and collect energy, then the terminal device can send an uplink signal to the network device, and collect energy through the charging signal sent by the network device.

[0360] In some embodiments, during the energy collection (energy storage) time [t1, t2], when there is neither a downlink signal (R2D signal, carrying signaling or data from the reader to the device) to be received nor an uplink signal (D2R signal, carrying signaling or data from the device to the reader) to be sent, the device is only in the energy collection state (i.e., the energy storage module is in working state and storing energy) and does not send or receive signals.

[0361] In some embodiments, the device is within the energy collection (energy storage) time [t1, t2], or within the energy collection (energy storage) time [t1, t2] and the collected energy is less than threshold 1, or the charging time is less than T1 and the device is within the energy collection (energy storage) time [t1, t2], which can include the following four situations:

[0362] (1) When there is a downlink signal to be received or an uplink signal to be sent, the device drops the reception of the downlink signal or the transmission of the uplink signal and only performs energy collection.

[0363] (2) When there is a downlink signal to be received, the device receives the downlink signal and collects energy at the same time, or does not collect energy (it waits until the downlink signal is received before collecting energy). When there is an uplink signal to be sent, the device sends the uplink signal and collects energy at the same time, or does not collect energy (it waits until the uplink signal is sent before collecting energy).

[0364] (3) When there is a downlink signal to be received, the device drops the reception of the downlink signal and collects energy at the same time. When there is an uplink signal to be sent, the device sends the uplink signal and collects energy at the same time, or does not collect energy (wait until the uplink signal is sent before collecting energy).

[0365] (4) When there is a downlink signal to be received, the device receives the downlink signal and collects energy at the same time, or does not collect energy (it waits until the uplink signal is sent before collecting energy). When there is an uplink signal to be sent, the device abandons (drops) the uplink signal and only collects energy.

[0366] Optionally, for the dropped uplink signal 1, when the energy to be collected is equal to threshold 1 or the charging time is greater than or equal to T1, there is no other uplink signal to be sent or the uplink signal 1 does not exceed the maximum time T max , and send the uplink signal 1 again.

[0367] In some embodiments, the device is within the energy collection (energy storage) time [t1, t2], and the collected energy is less than threshold 1 or the charging time is less than T1, but the collected energy is greater than or equal to threshold 2 (that is, the stored energy can support one or more communications) or the charging time is greater than T2. ​​The following three situations may occur:

[0368] (1) When a downlink signal needs to be received, the device receives the downlink signal and collects energy at the same time, or does not collect energy (it waits until the downlink signal is received before collecting energy). When an uplink signal needs to be sent, the device sends the uplink signal and collects energy at the same time, or does not collect energy (it collects energy after the uplink signal is sent). (Because there is a condition that meets threshold 2 or the charging time is longer than T2, it is sufficient to support one or more downlink receptions or uplink transmissions)

[0369] (2) When there is a downlink signal to be received, the device receives the downlink signal and collects energy at the same time, or does not collect energy (wait until the downlink signal is received before collecting energy). When there is an uplink signal to be sent, the device abandons (drops) the uplink signal and collects energy at the same time, or does not collect energy (collects energy after the uplink signal is sent). (Because there is a situation where threshold 2 is met or the charging time is longer than T2, but it is not enough to support one uplink signal transmission, if the power consumption of uplink signal transmission is greater than that of downlink reception).

[0370] (3) When there is an uplink signal to be sent, the device sends the uplink signal and collects energy at the same time, or does not collect energy (collects energy after sending the uplink signal). When there is a downlink signal to be received, the device abandons (drops) the reception of the downlink signal and collects energy at the same time. The following method is applicable to this situation:

[0371] Method 1: Threshold 2 is met or the charging time is longer than T2, but it is not enough to support the reception of a downlink signal. If the power consumption of receiving the downlink signal is greater than that of sending the uplink signal.

[0372] Method 2: There is a situation where, for example, the device is fully charged and receives and decodes downlink information once. When it is about to send uplink information again, it has no power. Therefore, it needs to collect energy and send uplink information first. After the uplink information is sent, downlink information needs to be received again, but the remaining power is not enough to receive the downlink information. In this case, the downlink reception is dropped.

[0373] Optionally, for the dropped uplink signal 1, when the energy to be collected is greater than or equal to threshold 2 or the charging time is greater than or equal to T2, there is no other uplink signal to be sent or the maximum time T is not exceeded. max , and send the uplink signal 1 again.

[0374] In some embodiments, when the energy collected by the device during energy collection (energy storage) is equal to threshold 1 or the charging time is equal to T1, the device does not collect energy, and the device enters a downlink signal receiving state, or an uplink signal sending state.

[0375] Based on the above three embodiments, threshold 1 is the threshold at which the device is fully charged with energy (electricity), and threshold 2 is the threshold at which the device is partially charged but not fully charged. Threshold 1 and threshold 2 can be voltage thresholds, current thresholds, received signal strength indication (RSSI) thresholds, etc. Threshold 1 and threshold 2 can be pre-configured, pre-defined, dynamically indicated by the network device, or determined by the UE itself. Optionally, the threshold 1 is determined by the type of the device. The threshold 1 is the same or different for different device types. For example, the threshold 1 for device 1 to be fully charged with energy (electricity) is smaller than the threshold 1 for device 2a to be fully charged with energy (electricity).

[0376] The duration T1 is the threshold for the device to be fully charged, and the duration T2 is the threshold for the device to be partially charged but not fully charged. T1 and T2 can be pre-configured, pre-defined, or determined by the network device or the UE implementation. T1 is related to the strength of the charging signal. The stronger the signal, the smaller T1. The T1 values ​​of different device types may be the same or different. For example, the time T1 for device 1 to be fully charged (electrical energy) is shorter than the T1 for device 2a to be fully charged (electrical energy).

[0377] The units of T1 and T2 are hours, minutes, seconds, milliseconds, microseconds, nanoseconds, etc., for example, 10ms; or, the units of T1 and T2 are radio frames, radio subframes, time slots, time domain symbols, for example, 10 time slots.

[0378] In some embodiments, when the device is not performing energy harvesting, the device enters a dormant state (light sleep state, etc.).

[0379] In some embodiments, the device collects energy (stores energy) within a time period [t1, t2], where [t1, t2] is a time window. This time window may be indicated by a network device, physical layer signaling, or high-layer signaling, or determined by the device itself.

[0380] In some embodiments, the device collects energy through a charging signal. The charging signal is sent by a node device within the topology (such as a base station or an intermediate node UE). It can be a downlink signal or a specific signal dedicated to charging the device, or a specific signal dedicated to charging the device sent by a node device outside the topology.
