The third type of IoT device has energy storage and independent signal amplification capabilities. Uplink transmission relies on backscatter transmission. Optionally, the peak power consumption of the third type of IoT device is less than or equal to several hundred µW. It should be noted that in some embodiments, several hundred µW, such as 100 µW or 200 µW, are examples provided for ease of understanding by those skilled in the art. That is, the peak power consumption is less than or equal to other hundreds-digit µW values, and this disclosure does not impose a specific limitation on this.

[0095] In some embodiments, the second device 102 can be a network device or intermediate node in an IoT scenario. In some embodiments, the second device 102 can perform inventory or paging on the first device 101.

The UPF can be used for packet routing and forwarding, policy enforcement, traffic reporting, and QoS (Quality of Service) processing. The SMF can be used for tunnel maintenance, IP address allocation and management, UP function selection, policy enforcement and QoS control, billing data collection, roaming, etc. The UDM can be used for 3GPP AKA (Authentication and Key Agreement) authentication, user identification, access authorization, registration, mobility, subscription, SMS management, etc.

[0098] In some embodiments, the second device 102 is, for example, an intermediate node in an IoT scenario. In some embodiments, the second device 102 may be, for example, a relay, an IAB (Integrated Access and Backhaul), a terminal, or a repeater.

The processes and information interactions between these internal interfaces can be implemented by software or programs.

[0100] In some embodiments, the access network device may be composed of a central unit (CU) and a distributed unit (DU). The CU may also be called a control unit. The CU-DU structure can separate the protocol layer of the access network device. Some of the protocol layer functions are centrally controlled by the CU, while the remaining part or all of the protocol layer functions are distributed in the DU and centrally controlled by the CU. However, this is not the only possibility.

Each main body may be physical or virtual. The connection relationship between the main bodies is illustrative. The main bodies may not be connected or may be connected. The connection can be in any way, it can be a direct connection or an indirect connection, it can be a wired connection or a wireless connection.

[0103] The embodiments disclosed herein can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), Future Radio Access (FRA), New-Radio Access Technology (RAT), New Radio (NR), New radio access (NX), Future generation radio access (FX), Global System for Mobile communications (GSM), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), and IEEE 802.20, Ultra-Wideband (UWB), Bluetooth (a registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X) systems, systems utilizing other communication methods, and next-generation systems built upon them, etc. Furthermore, multiple systems can be combined (e.g., a combination of LTE or LTE-A with 5G).

[0104] It's important to note that in today's IoT networks, traditional IoT devices are typically powered by conventional batteries with limited lifespans, negatively impacting user experience. The astronomical growth of IoT networks, coupled with the sheer number of IoT devices, has pushed maintenance costs, including labor and battery expenses, to unprecedented levels. Billions of conventional batteries are discarded annually, with only a fraction being effectively recycled, causing harmful impacts on the Earth's ecosystem. Maintaining IoT networks and replacing batteries can be extremely challenging under some extreme environmental conditions. In this regard, battery-free IoT communication has been proposed, which will improve network performance and sustainability and expand application scenarios. Furthermore, battery-free communication is more environmentally friendly and safer for children and the elderly. By eliminating conventional batteries, device size and cost can be significantly reduced, paving the way for a variety of new applications.

[0105] In the 5G era, various LPWA (Low Power Wide Area) technologies have been developed, such as MTC (Machine Type Communication), NB-IoT (Narrow Band Internet of Things), and RedCap (Reduced Capability), to meet the growing demands of vertical industries. These LPWA technologies achieve low cost, low power consumption, and massive connectivity, satisfying the requirements of many applications. However, many use cases and applications remain unresolved in the following situations: First, devices powered by traditional batteries are unsuitable, for example, under extreme environmental conditions (e.g., high voltage, extremely high / low temperatures, humid environments). Second, maintenance-free devices are required (e.g., traditional batteries that do not require replacement). Finally, ultra-low complexity, very small device size / form factor (e.g., thickness in millimeters), and longer lifespan are required.

[0106] Ambient power-enabled IoT is a promising technology that can address the aforementioned unmet needs. An ambient power-enabled IoT device is an IoT device powered by energy harvesting, without batteries or with limited energy storage capacity (e.g., using capacitors), providing energy by harvesting radio waves, light, motion, heat, or any other suitable source.

[0107] Energy harvested from the environment can power data transmission and wireless communication at sensing nodes. Current mainstream low-power IoT communication chips (such as BLE, LoRa, and NB-IoT) consume tens or even hundreds of milliwatts of power for transmission and reception, while environmental energy harvesting yields only microwatts, insufficient to power these types of nodes. Therefore, a new wireless communication technology is needed to reduce communication energy consumption to tens or even below ten microwatts. The current mainstream approach employs backscatter communication technology. Backscatter communication is one of the key technologies for building a green, energy-efficient, low-cost, and flexibly deployable future Internet of Things (IoT), and is an important means of realizing "intelligent interconnection of everything."

[0108] In some embodiments, backscatter communication utilizes the principle of radio frequency signal backscattering to design an extremely low-power modulation and transmission technology. For example, since a portion of the radio frequency signal is reflected when it reaches the surface of an object, the transmitting node adjusts the matching between the receiving antenna and impedance according to the information to be transmitted, enhancing the reflection of the incident radio frequency signal, and modulating the sensed data it acquires onto the reflected signal to complete the data transmission. This process is similar to a reflector. Compared to other communication technologies, backscatter communication does not require complex radio frequency structures, reducing the use of devices such as power amplifiers, high-precision crystal oscillators, duplexers, and high-precision filters. It also does not require complex baseband processing, thus simplifying terminal design and significantly reducing the cost of terminal nodes.

[0109] In some embodiments, backscatter communication can be widely used in RFID (Radio Frequency Identification) systems, resulting in many large-scale commercial applications. Its working principle is that the receiver (typically an RFID reader) sends a radio frequency excitation signal to activate a passive node (typically an RFID tag). The tag uses backscatter communication to modulate its own information onto the radio frequency signal. The reader receives the reflected signal from the passive tag and demodulates it to achieve information transmission.

[0110] Currently, RFID technology also has many drawbacks, such as short coverage distance (the wireless signal experiences double-path fading during communication, resulting in significant path loss and a short effective communication distance), single-channel transmission, the need for strict tag alignment, and lack of power control. There is significant room for improvement in the communication aspects of RFID technology. In some embodiments, it is necessary to integrate 3GPP communication technology to improve the wireless communication performance of RFID technology in passive IoT applications.

[0111] In communication systems, to save power and reduce device complexity, a new type of device has been introduced, such as the Ambient Internet of Things (AIoT) device (also called Ambient IoT or A-IoT). This A-IoT device (i.e., the first device 101 in this paper) needs to collect radio waves emitted by the surrounding environment or surrounding devices to obtain energy before it can operate. Therefore, before obtaining energy, the A-IoT device is usually in a "power-off" state, i.e., offline. For this reason, the communication system needs to support data communication methods with shorter transmission times, lower memory consumption, and more convenient terminal management to complete the data communication process as quickly as possible.

[0112] In some embodiments, this disclosure implements a wireless communication design based on backscattering technology for communication with an environmental energy device (also known as an environmental IoT device, i.e., the second device herein). Optionally, the aforementioned IoT device or environmental IoT device (also called an Ambient IoT device, or A-IoT device) can be applied to various different communication architectures in the communication system. Taking an A-IoT device as an example, Figures 2A-2E are schematic diagrams illustrating the architecture of an A-IoT device communicating with a network device and / or a terminal according to embodiments of this disclosure. Optionally, as shown in Figure 2A, the A-IoT device (i.e., the Ambient IoT device in Figure 2A) and the network device (such as a base station (BS)) can directly receive and transmit data or signals.

[0113] Optionally, as shown in Figure 2B, A-IoT devices and network devices (such as base stations (BS)) can indirectly receive and send data or signals through intermediate nodes. These intermediate nodes can be, for example, relays, integrated access backhaul (IAB) devices, terminals, or repeaters.

[0114] Optionally, as shown in Figure 2C, A-IoT devices and network devices (such as base stations (BS)) can directly transmit uplink data, and A-IoT devices and network devices (such as base stations (BS)) can indirectly transmit downlink data through intermediate nodes, such as relays, IAB devices, terminals, and repeaters.

[0115] Optionally, as shown in Figure 2D, downlink data can be transmitted directly between A-IoT devices and network devices (such as base stations (BS)), while uplink data can be transmitted indirectly between A-IoT devices and network devices (such as base stations (BS)) through intermediate nodes.

[0116] Optionally, as shown in Figure 2E, the A-IoT device and the terminal (or user equipment (UE)) can directly receive and send data. The terminal can be responsible for collecting data from the A-IoT device and forwarding the collected data to the network device.

[0117] In some embodiments of a passive IoT system, the data transmission type of an IoT device or an A-IoT device may include, but is not limited to, the following three types: DO-DTT, DT, and DO-A. DO-DTT (Device-originated–device-terminated triggered) can be understood as data triggered by the second device 102, such as data fed back during inventory processing; for example, the identifier of the first device 101, such as an EPC (Electronic Product Code) or a temporary identifier. DT (Device-terminated) can be understood as, for example, an access command; for example, data returned after the first device 101 executes an access command sent by the second device 102, for example, an ACK (acknowledgment) feedback. DO-A (Device-originated–autonomous) can be understood as data actively transmitted by the first device 101, such as active reporting triggered by sensor functions.

[0118] In some embodiments, the first message that triggers the first device 101 to initiate initial access may be called a paging message or an "initial trigger message". A paging message can page one, a group, or all IoT devices. If a paging message pages one IoT device, it triggers non-contention-based random access. The paged IoT device responds to the paging message on non-contention-based resources, for example, by sending an ACK message containing the IoT device's identifier, such as EPC. If a paging message triggers a group or all IoT devices, it triggers contention-based random access. The paged group or all IoT devices generate a random number based on a first parameter (which can be represented by "Q"), and then continue to receive at least one of Query messages, QueryAdjust messages, and QueryRepete messages until the random number decreases to 0, at which point they initiate random access again, for example, by sending the generated random number.

[0119] Passive IoT devices have limited power storage, and continuous command listening will lead to power consumption and failure to work due to power shortage. The charging process will also affect the device's command transmission and reception. Therefore, it is necessary to support the device's discontinuous reception and reduce the impact on command transmission and reception while ensuring power supply.

[0120] Based on this, embodiments of this disclosure propose a communication method, communication device, system, storage medium, and program product, which enable a first device in an IoT scenario to inform a second device of its own energy information through first information, so that the second device can understand the energy information of the first device in a timely and accurate manner, thereby enabling the device to support discontinuous reception and improving the reliability of transmission between devices in an IoT scenario.

[0121] Figure 3 is an interactive schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 3, the embodiments of the present disclosure relate to a communication method, which includes, but is not limited to, the following steps.

[0122] In step S3101, the first device 101 sends the first information to the second device 102.

[0123] In some embodiments, the first device 101 and the second device 102 can both be devices in an Internet of Things (IoT) scenario. In some embodiments, the first device 101 can be an IoT device, and the second device 102 can be a network device or an intermediate node.

[0124] In some embodiments, the first information may be sent by the first device 101 to the second device 102. For example, the first device 101 sends the first information to the second device 102, and correspondingly, the second device 102 receives the first information sent by the first device 101.

[0125] In some embodiments, the first information described above can be used to indicate the energy information of the first device 101. Exemplarily, the first information may include, but is not limited to, an indication of the energy information of the first device 101. Exemplarily, the first information can be an indication message that can be used to indicate the energy information of the first device 101. In some embodiments, terms such as "energy information," "power information," "energy status information," "power status information," "capacity information," "capacity status information," "energy," "power," "remaining energy," and "remaining power" can be used interchangeably.

[0126] In some embodiments, the energy information of the first device 101 may include, but is not limited to, the energy of the first device 101 being higher or lower than a first energy threshold. For example, the energy information of the first device 101 may include, but is not limited to, the energy of the first device 101 being higher than the first energy threshold, or the energy information of the first device 101 may include, but is not limited to, the energy of the first device 101 being lower than the first energy threshold.

[0127] In some embodiments, the energy information of the first device 101 may include, but is not limited to: the energy of the first device 101 is greater than or equal to (≥) a first energy threshold, or less than or equal to (≤) a first energy threshold. For example, the energy information of the first device 101 may include, but is not limited to: the energy of the first device 101 is greater than or equal to the first energy threshold, or the energy information of the first device 101 may include, but is not limited to: the energy of the first device 101 is less than or equal to the first energy threshold.

[0128] Optionally, in some embodiments, the energy information of the first device 101 may include, but is not limited to, whether the energy of the first device 101 is greater than or equal to a first energy threshold. For example, the energy information of the first device 101 may include: the energy of the first device 101 is greater than or equal to the first energy threshold; or, the energy information of the first device 101 may include: the energy of the first device 101 is less than the first energy threshold. In some embodiments, "energy" as used herein may be, for example, remaining energy; for instance, the energy of the first device 101 may be the remaining energy of the first device 101.

[0129] In some embodiments, the energy information of the first device 101 may include, but is not limited to, whether the energy of the first device 101 is less than or equal to a first energy threshold. For example, the energy information of the first device 101 may include: the energy of the first device 101 is greater than the first energy threshold, or the energy information of the first device 101 may include: the energy of the first device 101 is less than or equal to the first energy threshold.

[0130] In some embodiments, the energy information of the first device 101 may include, but is not limited to, the energy of the first device 101 being greater than or less than a first energy threshold. For example, the energy information of the first device 101 may include: the energy of the first device 101 being greater than the first energy threshold; or, the energy information of the first device 101 may include: the energy of the first device 101 being less than the first energy threshold. For example, the energy information of the first device 101 may include: the energy of the first device 101 being greater than or equal to the first energy threshold; or, the energy information of the first device 101 may include: the energy of the first device 101 being less than the first energy threshold. For example, the energy information of the first device 101 may include: the energy of the first device 101 being less than or equal to the first energy threshold; or, the energy information of the first device 101 may include: the energy of the first device 101 being greater than the first energy threshold.

[0131] In some embodiments, the first energy threshold herein may be configurable, pre-configurable, or protocol-defined. In some embodiments, the first device 101 may determine the first energy threshold based on the configuration or pre-configuration of the second device 102. For example, the first energy threshold may be configured or pre-configured by the second device 102; for instance, the second device 102 configures or pre-configures the first energy threshold for the first device 101, and correspondingly, the first device 101 may determine the first energy threshold based on the configuration or pre-configuration of the second device 102.

[0132] In some embodiments, the first device 101 may determine the first energy threshold based on a protocol specification. For example, the first energy threshold may be specified in a protocol, and the first device 101 may determine the first energy threshold based on the protocol specification.

[0133] In some embodiments, the first device 101 may determine the first energy threshold based on an implementation. For example, the first device 101 may determine a first energy threshold that matches the application scenario. For instance, if the first device 101 needs to consume a large amount of power in a certain application scenario, then the first energy threshold will also be relatively large. Or, if the first device 101 needs to consume a small amount of power in a certain application scenario, then the first energy threshold will also be relatively small.

[0134] In some embodiments, the first energy threshold herein can be any of an absolute value, an absolute value range, a proportional value, or a proportional value range. For example, the first energy threshold can be an absolute value, such as an absolute numerical value, with units such as milliwatts (mW), microwatts (uW), watts (W), etc. For example, the first energy threshold can be a proportional value, such as the percentage of remaining energy to total energy. For example, the first energy threshold can be an absolute value range, such as the set of all absolute values ​​between absolute value 1 and absolute value 2, which may include the given absolute value 1 and absolute value 2 (e.g., represented by [absolute value 1, absolute value 2]), or may include a given absolute value 1 but not absolute value 2 (e.g., represented by [absolute value 1, absolute value 2)), or may include a given absolute value 2 but not absolute value 1 (e.g., represented by (absolute value 1, absolute value 2]), or may not include absolute value 1 and absolute value 2 (e.g., represented by (absolute value 1, absolute value 2)). For example, the first energy threshold can be a proportional value. For example, 50% can be used to indicate the percentage of remaining energy. For instance, the first energy threshold can be a range of percentage values, such as the set of all percentage values ​​between percentage value 1 and percentage value 2, which may include the given percentage value 1 and percentage value 2 (e.g., represented by [percentage value 1, percentage value 2]), or may include the given percentage value 1 but not percentage value 2 (e.g., represented by [percentage value 1, percentage value 2)), or may include the given percentage value 2 but not percentage value 1 (e.g., represented by (percentage value 1, percentage value 2]), or may not include percentage value 1 and percentage value 2 (e.g., represented by (percentage value 1, percentage value 2)).

[0135] In some embodiments, the number of bits occupied by the first information can be 1. For example, the first information can be 1-bit indication information, which can be used to indicate whether the remaining energy is higher than a first energy threshold. In some embodiments, the first information can satisfy one or more of the following: the first information is set to a first value, which can indicate that the energy of the first device 101 is higher than the first energy threshold; the first information is set to a second value, which can indicate that the energy of the first device 101 is lower than the first energy threshold; the first information is defaulted, which can indicate that the energy of the first device 101 is higher than the first energy threshold, or it can indicate that the energy of the first device 101 is lower than the first energy threshold. For example, the first value can be 1 and the second value can be 0; or the first value can be 0 and the second value can be 1; or the first value and the second value can also use other values ​​to indicate the first information. This disclosure does not limit this, nor will it elaborate further.

[0136] For example, if the first energy threshold is an absolute value, setting the first information to a first value can indicate that the energy of the first device 101 is higher than the absolute value; setting the first information to a second value can indicate that the energy of the first device 101 is lower than the absolute value. In some embodiments, "higher than" can be equivalent to "greater than or equal to," and "lower than" can be equivalent to "less than." For example, if the first energy threshold is an absolute value, setting the first information to a first value can indicate that the energy of the first device 101 is greater than or equal to the absolute value; setting the first information to a second value can indicate that the energy of the first device 101 is less than the absolute value. In some embodiments, "higher than" can be equivalent to "greater than," and "lower than" can be equivalent to "less than or equal to." For example, if the first energy threshold is an absolute value, setting the first information to a first value can indicate that the energy of the first device 101 is greater than the absolute value; setting the first information to a second value can indicate that the energy of the first device 101 is less than or equal to the absolute value.

[0137] For example, if the first energy threshold is an absolute value range, setting the first information to a first value can indicate that the energy of the first device 101 is within that absolute value range; setting the first information to a second value can indicate that the energy of the first device 101 is not within that absolute value range. In some embodiments, terms such as "being in" and "falling into" can be used interchangeably; terms such as "not being in", "not being in", "not falling into", and "not falling into" can be used interchangeably.

[0138] For example, if the first energy threshold is a proportional value, setting the first information to a first value can indicate that the energy of the first device 101 is higher than the proportional value (relative to full energy or full charge); setting the first information to a second value can indicate that the energy of the first device 101 is lower than the proportional value. In some embodiments, "higher than" can be equivalent to "greater than or equal to," and "lower than" can be equivalent to "less than." For example, if the first energy threshold is a proportional value, setting the first information to a first value can indicate that the energy of the first device 101 is greater than or equal to the proportional value; setting the first information to a second value can indicate that the energy of the first device 101 is less than the proportional value. In some embodiments, "higher than" can be equivalent to "greater than," and "lower than" can be equivalent to "less than or equal to." For example, if the first energy threshold is a proportional value, setting the first information to a first value can indicate that the energy of the first device 101 is greater than the proportional value; setting the first information to a second value can indicate that the energy of the first device 101 is less than or equal to the proportional value.

[0139] For example, if the first energy threshold is a proportional value range, the first information is set to a first value, which can indicate that the energy of the first device 101 is within the proportional value range; if the first information is set to a second value, it can indicate that the energy of the first device 101 is not within the proportional value range.

[0140] In some embodiments, the first information is omitted, which may indicate that the energy of the first device 101 is higher than a first energy threshold. For example, if the first information is omitted, it may indicate that the energy of the first device 101 is higher than the first energy threshold; if the first information is not omitted, it may indicate that the energy of the first device 101 is lower than the first energy threshold. For example, if the first energy threshold is an absolute value, the omission of the first information may indicate that the energy of the first device 101 is higher than the absolute value; if the first information is not omitted, it may indicate that the energy of the first device 101 is lower than the absolute value. In some embodiments, "higher than" may be equivalent to "greater than or equal to," and "lower than" may be equivalent to "less than." For example, if the first energy threshold is an absolute value, the omission of the first information may indicate that the energy of the first device 101 is greater than or equal to the absolute value; if the first information is not omitted, it may indicate that the energy of the first device 101 is lower than the absolute value. In some embodiments, "higher than" can be equivalent to "greater than", and "lower than" can be equivalent to "less than or equal to". For example, if the first energy threshold is an absolute value, the first information is omitted, which can indicate that the energy of the first device 101 is greater than the absolute value. If the first information is not omitted, it can indicate that the energy of the first device 101 is less than or equal to the absolute value.

[0141] For example, if the first energy threshold is an absolute value range, the first information is defaulted, which can indicate that the energy of the first device 101 is within the absolute value range. If the first information is not defaulted, it can indicate that the energy of the first device 101 is not within the absolute value range.

[0142] For example, if the first energy threshold is a proportional value, and the first information is omitted, it can indicate that the energy of the first device 101 is higher than the proportional value (relative to full energy or full charge). If the first information is not omitted, it can indicate that the energy of the first device 101 is lower than the proportional value. In some embodiments, "higher than" can be equivalent to "greater than or equal to", and "lower than" can be equivalent to "less than". For example, if the first energy threshold is a proportional value, and the first information is omitted, it can indicate that the energy of the first device 101 is greater than or equal to the proportional value. If the first information is not omitted, it can indicate that the energy of the first device 101 is less than the proportional value. In some embodiments, "higher than" can be equivalent to "greater than", and "lower than" can be equivalent to "less than or equal to". For example, if the first energy threshold is a proportional value, and the first information is omitted, it can indicate that the energy of the first device 101 is greater than the proportional value. If the first information is not omitted, it can indicate that the energy of the first device 101 is less than or equal to the proportional value.

[0143] For example, if the first energy threshold is a proportional value range, the first information is defaulted, which can indicate that the energy of the first device 101 is within the proportional value range. If the first information is not defaulted, it can indicate that the energy of the first device 101 is not within the proportional value range.

[0144] In some embodiments, the first information is omitted, which may indicate that the energy of the first device 101 is lower than a first energy threshold. For example, if the first information is omitted, it may indicate that the energy of the first device 101 is lower than the first energy threshold; if the first information is not omitted, it may indicate that the energy of the first device 101 is higher than the first energy threshold. For example, if the first energy threshold is an absolute value, the omission of the first information may indicate that the energy of the first device 101 is lower than the absolute value; if the first information is not omitted, it may indicate that the energy of the first device 101 is higher than the absolute value. In some embodiments, "higher than" may be equivalent to "greater than or equal to," and "lower than" may be equivalent to "less than." For example, if the first energy threshold is an absolute value, the omission of the first information may indicate that the energy of the first device 101 is less than the absolute value; if the first information is not omitted, it may indicate that the energy of the first device 101 is greater than or equal to the absolute value. In some embodiments, "higher than" can be equivalent to "greater than", and "lower than" can be equivalent to "less than or equal to". For example, if the first energy threshold is an absolute value, the first information is omitted, which can indicate that the energy of the first device 101 is less than or equal to the absolute value. If the first information is not omitted, it can indicate that the energy of the first device 101 is greater than the absolute value.

[0145] For example, if the first energy threshold is an absolute value range, the first information is defaulted, which can indicate that the energy of the first device 101 is not in the absolute value range; if the first information is not defaulted, it can indicate that the energy of the first device 101 is in the absolute value range.

[0146] For example, if the first energy threshold is a proportional value, and the first information is omitted, it can indicate that the energy of the first device 101 is lower than the proportional value (a proportion relative to full energy or full charge). If the first information is not omitted, it can indicate that the energy of the first device 101 is higher than the proportional value. In some embodiments, "higher than" can be equivalent to "greater than or equal to", and "lower than" can be equivalent to "less than". For example, if the first energy threshold is a proportional value, and the first information is omitted, it can indicate that the energy of the first device 101 is lower than the proportional value. If the first information is not omitted, it can indicate that the energy of the first device 101 is greater than or equal to the proportional value. In some embodiments, "higher than" can be equivalent to "greater than", and "lower than" can be equivalent to "less than or equal to". For example, if the first energy threshold is a proportional value, and the first information is omitted, it can indicate that the energy of the first device 101 is less than or equal to the proportional value. If the first information is not omitted, it can indicate that the energy of the first device 101 is greater than the proportional value.

[0147] For example, if the first energy threshold is a proportional value range, the first information is defaulted, which can indicate that the energy of the first device 101 is not in the proportional value range; if the first information is not defaulted, it can indicate that the energy of the first device 101 is in the proportional value range.

[0148] In some embodiments, the number of bits occupied by the first information can be greater than 1. In other words, the number of bits occupied by the first information can be multiple. For example, the number of bits occupied by the first information can be 2. If the first energy threshold is an absolute value range, then the absolute value range can be 4. For example, when the first information is 00, 01, 10, 11, it can indicate different absolute value ranges, but it is not limited to this and will not be elaborated here.

[0149] In some embodiments, the aforementioned first information may be carried in a first transmission, which may be a transmission from the first device 101 to the second device 102. In some embodiments, the first transmission may include, but is not limited to, any of the following: message 1 (MSG 1) in a 3-step contention-based random access (3-step CBRA); message 3 (MSG 3) in a 3-step contention-based random access (3-step CBRA); message 1 (MSG 1) in a 2-step contention-based random access (2-step CBRA); message 1 (MSG 1) in a contention-free random access (CFRA); a response message to a first command, which may be a command responded to by the first device 101; and a first segment of the response message to the first command.

[0150] For example, the first transmission may be message 1 in a 3-step CBRA. The first information in this document may be carried in message 1 of the 3-step CBRA. For example, when the first device 101 determines that a 3-step CBRA is triggered, the first device 101 sends message 1 of the 3-step CBRA to the second device 102. Message 1 of the 3-step CBRA may include the first information. For example, the first transmission may include a random number. For example, message 1 of the 3-step CBRA may include the random number, such as a 16-bit random number. Optionally, the random number may be generated by the first device 101 based on a first parameter (which may be represented by "Q"). When the first device 101 sends message 1 of the 3-step CBRA to the second device 102, message 1 of the 3-step CBRA includes the generated random number and may also include the first information.

[0151] For example, the first transmission may be message 3 in a 3-step CBRA. The first information in this document may be carried in message 3 of the 3-step CBRA. For instance, when the first device 101 determines that a 3-step CBRA is triggered, the first device 101 sends message 3 of the 3-step CBRA to the second device 102. Message 3 of the 3-step CBRA may include the first information. For example, the first transmission may include the identifier of the first device 101. The identifier of the first device 101 may be a device identifier, such as an identifier assigned by an EPC or core network device.

[0152] For example, the first transmission can be message 1 in a 2-step CBRA. The first information in this document can be carried in message 1 of the 2-step CBRA. For example, when the first device 101 determines that a 2-step CBRA is triggered, the first device 101 sends message 1 of the 2-step CBRA to the second device 102. Message 1 of the 2-step CBRA can include the first information. For example, the first transmission can include at least one of a random number and the identifier of the first device 101. For example, message 1 of the 2-step CBRA can include at least one of a random number and the identifier of the first device 101. The random number can be, for example, a 16-bit random number. The description of the random number can be found in the description of the random number in message 1 of the 3-step CBRA above, and will not be repeated here. The identifier of the first device 101 can be a device identifier, such as an identifier assigned by an EPC or core network device.

[0153] For example, the first transmission can be message 1 in CFRA. The first information in this document can be carried in message 1 of CFRA. For instance, when the first device 101 determines that CFRA is triggered, the first device 101 sends message 1 of CFRA to the second device 102. Message 1 of CFRA may include the first information. For example, the first transmission may include at least one of a random number and the identifier of the first device 101. For instance, message 1 of CFRA may include at least one of a random number and the identifier of the first device 101. The random number may be, for example, a 16-bit random number. The description of the random number can be found in the description of the random number in message 1 of the three-step CBRA mentioned above, and will not be repeated here. The identifier of the first device 101 can be a device identifier, such as an identifier assigned by an EPC or core network device.

[0154] For example, the first transmission can be a response message to a first command, which can be a command responded to by the first device 101. The first information mentioned herein can be carried in the response message to the first command. In other words, the response message to the first command sent by the first device 101 to the second device 102 can include the first information. For example, the first command can be a command that the first device 101 needs to respond to, such as a Read command, a Write command, a Kill command, or a Disable command, etc. For example, the response message to the first command can be an ACK message, but is not limited to this. For example, if the first command is a Read command, the response message to the first command can be reading the specified content in the memory of the first device 101.

[0155] For example, the first transmission can be a first segment of a response message to a first command, where the first command can be a command responded to by the first device 101. The first information mentioned herein can be carried in one or more segments of the response message to the first command. In other words, the response message to the first command sent by the first device 101 to the second device 102 supports segmented transmission. When the first device 101 sends the first segment of the response message to the second device 102, the first segment carries the first information. For example, the first segment can be the first segment of the response message to the first command, but is not limited to this. For instance, the first segment can be any segment of the response message to the first command, such as the last segment.

[0156] In some embodiments, the first information may indicate whether the first device 101 is capable of sending the first message. For example, the first information sent by the first device 101 to the second device 102 may include an indication of the energy information of the first device 101, which may include, but is not limited to, whether the first device 101 is capable of sending the first message. In some embodiments, the first information may be carried in a first transmission, which may be a transmission from the first device 101 to the second device 102.

[0157] In some embodiments, the first transmission can be message 1 in a 3-step CBRA, and the first message can be message 3 in a 3-step CBRA. Message 1 in the 3-step CBRA may carry first information. For example, the first information in message 1 in the 3-step CBRA may indicate whether the first device 101 can complete the transmission of the first message. For example, the description of message 1 in the 3-step CBRA can be found in the description of the above embodiments, and will not be repeated here. For example, the first message can be message 3 in the 3-step CBRA, and message 3 in the 3-step CBRA may include the identifier of the first device 101. For example, the identifier of the first device 101 may be a device identifier, such as an identifier assigned by the EPC or core network. For example, the first information contained in message 1 in the 3-step CBRA may be used to indicate whether the first device can complete the transmission of message 3 in the 3-step CBRA.

[0158] In some embodiments, the first transmission can be message 3 in a 3-step CBRA, and the first message can be a response message to a second command. The second command can be a predefined command for the first device 101, for example, the second command is defined as a read command, and the first message is the response message to the read command, such as reading specified content from the memory of the first device 101. Message 3 in the 3-step CBRA can carry first information. For example, the first information in message 3 in the 3-step CBRA can indicate whether the first device 101 can complete the transmission of the first message. For example, the first information contained in message 3 in the 3-step CBRA can be used to indicate whether the first device 101 can complete the transmission of the response message to the second command. The second command can be a predefined command, for example, a command agreed upon by the first device and the second device, or it can be understood that the second command refers to a command that maintains consistency between the second device 102 and the first device 101, for example, it is stipulated that the response to the read command is used to determine whether the transmission can be completed. Alternatively, the second command can be a predefined command, such as a write command or a kill / disable command; in short, it is a predefined command between the second device and the first device. This predefined command can be any of the Read, Write, Kill, or Disable commands. For example, the description of message 3 in the 3-step CBRA can be found in the description of the above embodiments, and will not be repeated here.

[0159] In some embodiments, the first transmission may be message 3 in a 3-step CBRA, and the first message may be message 3 in a 3-step CBRA, which may carry first information. For example, the first information in message 3 in a 3-step CBRA may indicate whether the transmission of the first message can be completed, that is, the first information in message 3 in a 3-step CBRA may indicate whether the first device 101 can complete the retransmission of message 3 in a 3-step CBRA. For example, if random access fails, the second device 102 may trigger the retransmission of message 3 in a 3-step CBRA, and the first information may indicate whether the retransmission of message 3 in a 3-step CBRA can be completed.

[0160] In some embodiments, the first transmission can be message 1 in CFRA, the first message can be a response message to a second command, and the second command can be a predefined command for the first device 101, such as a read command, and the first message is a response message to the read command, for example, reading specified content from the memory of the first device 101. Message 1 in CFRA can carry first information. For example, the first information in message 1 in CFRA can indicate whether the first device 101 can complete the transmission of the first message; for example, the first information in message 1 in CFRA can indicate whether the transmission of the response message to the second command can be completed. For example, the description of message 1 in CFRA can be found in the description of the above embodiments, and will not be repeated here. For example, the description of the second command and the response message to the second command can be found in the description of the above embodiments, and will not be repeated here.

[0161] In some embodiments, the first transmission may be message 1 in a 2-step CBRA. The first message may be message 1 in a 2-step CBRA, and message 1 in the 2-step CBRA may carry first information. The first information in message 1 in the 2-step CBRA may indicate whether the first device 101 can complete the transmission of the first message. For example, the description of message 1 in the 2-step CBRA can be found in the description of the above embodiments, and will not be repeated here. For example, the first message may be message 1 in a 2-step CBRA, that is, the first information in message 1 in the 2-step CBRA may indicate whether the first device 101 can complete the retransmission of message 1 in the 2-step CBRA, for example, for re-accessing and retransmitting message 1 when contention resolution fails.

[0162] In some embodiments, the first transmission can be message 1 in a two-step CBRA, and the first message can be a response message to a second command. The second command can be a predefined command for the first device 101, for example, the second command is defined as a read command, and the first message is a response message to the read command, such as reading specified content from the memory of the first device 101. Message 1 in the two-step CBRA can carry first information. Exemplarily, the first information in message 1 in the two-step CBRA can indicate whether the first device 101 can complete the transmission of the first message. Exemplarily, the description of message 1 in the two-step CBRA can be found in the description of the above embodiments, and will not be repeated here. Exemplarily, the first message can be message 1 in the two-step CBRA, that is, the first information in message 1 in the two-step CBRA can indicate whether the first device 101 can complete the transmission of the response message to the second command. Exemplarily, the description of the second command and the response message to the second command can be found in the description of the above embodiments, and will not be repeated here.

[0163] In some embodiments, the first transmission can be a response message to a first command, and the first message can be a response message to a second command. The second command can be a predefined command for the first device 101, for example, the second command might be a read command, and the first message would be a response message to the read command, such as reading specified content from the memory of the first device 101. The response message to the first command may carry first information. For example, the first information in the response message to the first command may indicate whether the first device 101 can complete the transmission of the first message. For example, the first information included in the response message to the first command may indicate whether the transmission of the response message to the second command can be completed. For example, the description of the first command and the response message to the first command can be found in the description of the above embodiments, and will not be repeated here. The description of the second command and the response message to the second command can be found in the description of the above embodiments, and will not be repeated here. For example, the first command and the second command may be the same command or different commands, and no specific limitation is made here.

[0164] In some embodiments, the first transmission may be a first segment of a response message to a first command, and the first message may be the remaining segment following the first segment. The first segment of the response message to the first command may carry first information. For example, the first information included in the first segment of the response message to the first command may indicate whether the first device 101 can complete the transmission of the remaining segment following the first segment. For example, the first segment may be the first segment of the response message to the first command, but is not limited to this; for example, the first segment may be the second segment or the third segment of the response message to the first command, etc. For example, the first message may be the remaining segment following the first segment. For example, if the first device 101 needs to segment the response message to the first command, the first information in the first segment of the response message may indicate whether the first device 101 can complete the transmission of the remaining segment (i.e., the response message minus the first segment). For example, in the first information of the second segment, the first device 101 indicates whether the first device 101 can complete the transmission of the remaining segments (i.e., the remaining segments after subtracting the first and second segments from the response message), that is, whether the transmission of the remaining data can be completed.

[0165] In some embodiments, when the first information can indicate whether the first device 101 can complete the transmission of the first message, the first information can satisfy one or more of the following: the first information is set to a third value, which can indicate that the first device 101 can complete the transmission of the first message; the first information is set to a fourth value, which can indicate that the first device 101 cannot complete the transmission of the first message; the first information is defaulted, which can indicate that the first device 101 can complete the transmission of the first message, or can indicate that the first device 101 cannot complete the transmission of the first message. For example, the third value is 1, the fourth value is 0, the first information is set to 1, which can indicate that the first device 101 can complete the transmission of the first message, and the first information is set to 0, which can indicate that the first device 101 cannot complete the transmission of the first message. For example, the third value can be 0, the fourth value can be 1, or the third value and the third value can also adopt other values ​​to achieve the indication of the first information. This disclosure does not limit this, nor will it elaborate further.

[0166] In some embodiments, where the first information can indicate whether the first device 101 can complete the transmission of the first message, the first information is omitted, which can indicate that the first device 101 can complete the transmission of the first message. For example, the omission of the first information can indicate that the first device 101 can complete the transmission of the first message; if the first information is not omitted, it can indicate that the first device 101 cannot complete the transmission of the first message. In some embodiments, the omission of the first information can indicate that the first device 101 cannot complete the transmission of the first message. For example, the omission of the first information can indicate that the first device 101 cannot complete the transmission of the first message; if the first information is not omitted, it can indicate that the first device 101 can complete the transmission of the first message. In some embodiments, the terms "transmission of the first message" and "transmission of the first message" can be used interchangeably.

[0167] In step S3102, the second device 102 determines the energy information of the first device 101 based on the first information.

[0168] In some embodiments, the second device 102 receives first information from the first device 101, and the second device 102 can determine the energy information of the first device 101 based on the first information. The relevant description of the first information can be found in the description of the first information in step S3101 above, and will not be repeated here.

[0169] For example, if the energy information of the first device 101 includes whether the energy of the first device is higher or lower than a first energy threshold, the second device 102 determines that the value of the received first information is a first value, and the second device 102 can determine that the energy of the first device 101 is higher than the first energy threshold. Alternatively, the second device 102 determines that the value of the received first information is a second value, and the second device 102 can determine that the energy of the first device 101 is lower than the first energy threshold. The relevant description of the first energy threshold can be found in the description of the first energy threshold in step S3101 above, and will not be repeated here.

[0170] For example, if the energy information of the first device 101 includes whether the first device can complete the transmission of the first message, and the second device 102 determines that the received value of the first message is a third value, the second device 102 can determine that the first device 101 can complete the transmission of the first message. Alternatively, if the second device 102 determines that the received value of the first message is a fourth value, the second device 102 can determine that the first device 101 cannot complete the transmission of the first message. The relevant descriptions of the first information and the first message can be found in the description of the first information and the first message in step S3101 above, and will not be repeated here.

[0171] In some embodiments, the second device 102 may instruct the first device 101 whether to report energy information. If the second device 102 instructs the first device 101 to report energy information, the first device 101 sends a first message to the second device 102, the first message including an indication of the energy information of the first device 101. Optionally, in some embodiments, the second device 102 may instruct the first device 101 whether to report energy information via a second message. For example, the second message may be a second transmission, which may be a transmission from the second device 102 to the first device 101. For example, the second transmission may include, but is not limited to, any of the following: a paging message, message 2 (MSG2) in a 3-step CBRA, message 2 (MSG2) in a 2-step CBRA, a command, etc. For example, the command may include, but is not limited to, any of the following: Read, Write, Disable, Kill, etc. For example, the second message may carry indication information to instruct the first device 101 whether to report energy information. For example, this indication information may occupy 1 bit. Setting the indication information to a first value instructs the first device 101 to report energy information; setting it to a second value instructs the first device 101 not to report energy information. For instance, when the second device 102 sends a second message to the first device 101, and the first device 101 receives the second message, if the indication information in the second message is set to the first value, the first device 101 can determine that it needs to report energy information. The first device 101 can then send a first message to the second device 102, which includes an indication of the first device 101's energy information. If the indication information in the second message is set to the second value, the first device 101 can determine that it does not need to report energy information, and steps S3101 and S3102 can be omitted in this case.

[0172] In some embodiments, the second device 102 can instruct the first device 101 to report energy information via a third command. Optionally, in some embodiments, the third command can be a paging message or a new command. For example, defining a new command can instruct the first device 101 to report energy information. Exemplarily, the third command can carry the device identifier of the IoT device, such as a single device identifier, a group identifier, a list of device identifiers, or no device identifier. Optionally, carrying a device identifier in the third command can instruct the IoT device associated with that device identifier to report energy information. For example, if the identifier of the first device 101 matches (e.g., is the same) the device identifier carried in the third command, the first device 101 can determine that it needs to report energy information, and the first device 101 can send first information to the second device 102, which includes an indication of the energy information of the first device 101. For example, the third command carries a group identifier, which can instruct the IoT devices associated with that group identifier to report energy information. For instance, if the group identifier of the group to which the first device 101 belongs matches the group identifier carried in the third command, the first device 101 can determine that it needs to report energy information, and the first device 101 can send a first message to the second device 102, the first message including an indication of the energy information of the first device 101. Alternatively, the third command can carry a list of device identifiers, which can instruct the IoT devices associated with each device identifier in the list to report energy information. For instance, if the identifier of the first device 101 is included in the list of device identifiers carried in the third command, the first device 101 can determine that it needs to report energy information, and the first device 101 can send a first message to the second device 102, the first message including an indication of the energy information of the first device 101. For example, the third command does not carry a device identifier, but can instruct all IoT devices that receive the third command to report energy information. For instance, if the first device 101 receives the third command, the first device 101 can determine that it needs to report energy information. The first device 101 can send a first message to the second device 102, which includes an indication of the energy information of the first device 101.

[0173] In some embodiments, the first device 101 may determine whether to report energy information based on preset conditions. These preset conditions may be specified by a protocol or configured or pre-configured by the second device 102. For example, the remaining battery power may be less than a preset threshold. Alternatively, the preset conditions may be, for example, the remaining battery power may be greater than a preset threshold. These preset thresholds may be specified by a protocol or configured or pre-configured by the second device 102. When the preset conditions are met, the first device 101 reports energy information and may send first information to the second device 102, which includes an indication of the energy information of the first device 101. When the preset conditions are not met, the first device 101 does not report energy information, and steps S3101 and S3102 can be omitted in this case.

[0174] In some embodiments, if the first device 101 receives a second message or a third command sent by the second device 102, the first device 101 can determine whether to report energy information based on the second message or the third command, wherein the second message is used to instruct the first device whether to report energy information, and the third command is used to instruct the reporting of energy information. In some embodiments, if the first device 101 does not receive a second message or a third command sent by the second device 102, the first device 101 can determine whether to report energy information according to preset conditions. That is, if the second device 102 explicitly instructs through a second message or a third command, the first device 101 can determine whether to report energy information according to the instruction of the second device 102. If the second device 102 does not explicitly instruct through a second message or a third command, the first device 101 can determine whether to report energy information according to preset conditions.

[0186] In step S4101, the first device 101 sends first information to the second device 102, the first information including an indication of the energy information of the first device. Both the first device and the second device are devices in an Internet of Things (IoT) scenario.

[0187] In some embodiments, the first device is an Internet of Things (IoT) device, and the second device is a network device or an intermediate node.

[0188] In some embodiments, the energy information of the first device includes at least one of the following: the energy of the first device is higher or lower than a first energy threshold; whether the first device is able to complete the transmission of the first message. This clarifies the meaning of the first information indication, allowing the first device to accurately set the first information, and the second device to accurately interpret the meaning of the first information, thus ensuring reliable communication between the first and second devices.

[0189] In some embodiments, first information is carried in a first transmission, which is a transmission from a first device to a second device. The first transmission may include, but is not limited to, any of the following: message 1 in a 3-step contention-based random access CBRA; message 3 in a 3-step contention-based random access CBRA; message 1 in a 2-step contention-based random access CBRA; message 1 in a non-contention-based random access CFRA; a response message to a first command, where the first command is a command that the first device needs to respond to; and a first segment of the response message to the first command.

[0190] In some embodiments, the first information satisfies one or more of the following: the first information is set to a first value, indicating that the energy of the first device is higher than a first energy threshold; the first information is set to a second value, indicating that the energy of the first device is lower than the first energy threshold; the first information is defaulted, indicating that the energy of the first device is higher than the first energy threshold, or indicating that the energy of the first device is lower than the first energy threshold.

[0191] In some embodiments, the first energy threshold is any one of an absolute value, an absolute value range, a proportional value, or a proportional value range.

[0192] In some embodiments, the method further includes: determining a first energy threshold based on a second device configuration or pre-configuration; or, determining a first energy threshold based on protocol specifications.

[0193] In some embodiments, the first transmission is message 1 in a 3-step CBRA, and the first message is message 3 in a 3-step CBRA; or, the first transmission is message 3 in a 3-step CBRA, and the first message is a response message to a second command, the second command being a command agreed upon by the first device and the second device; or, the first transmission is message 1 in a CFRA, and the first message is a response message to a second command; or, the first transmission is message 1 in a 2-step CBRA, the first message is message 1 in a 2-step CBRA, or the first message is a response message to a second command; or, the first transmission is a response message to a first command, the first message is a response message to a second command, or, the first transmission is a first segment of a response message to a first command, and the first message is the remaining segment following the first segment.

[0194] In some embodiments, the first information satisfies one or more of the following: the first information is set to a third value, indicating that the first device can complete the transmission of the first message; the first information is set to a fourth value, indicating that the first device cannot complete the transmission of the first message; the first information is defaulted, indicating that the first device can complete the transmission of the first message, or indicating that the first device cannot complete the transmission of the first message.

[0195] In some embodiments, the first information occupies 1 bit.

[0196] In some embodiments, the steps and their optional implementations in other embodiments described before or after this embodiment, as well as other related parts in the specification, can be referred to, and will not be repeated here.

[0197] It is worth noting that the embodiments of this disclosure provide a communication method, particularly a method for indicating energy information. This method further clarifies the meaning of the indication information used to indicate the energy information of the first device 101. By clarifying the meaning of the indication information, the first device 101 can accurately set the indication information, and the second device 102 can accurately interpret the meaning of the indication information. This facilitates the second device to understand the energy information of the first device in a timely and accurate manner, improving the reliability of transmission between the first and second devices and providing conditions for the first device to support discontinuous reception. The following will describe the embodiments in detail.

[0198] In some embodiments, the first information is used to indicate whether the energy is higher or lower than a preset first energy threshold.

[0199] For example, the first energy threshold can be configured, pre-configured, or specified by a protocol. For example, the first energy threshold can be an absolute value, such as an absolute numerical value, with units such as milliwatts (mW), microwatts (uW), watts (W), etc. The first energy threshold can be an absolute value range, such as [absolute value 1, absolute value 2]. For example, the first energy threshold can be a percentage value, such as 50%, used to indicate the percentage of remaining energy. For example, the first energy threshold can be a percentage value range, such as [percentage value 1, percentage value 2].

[0200] For example, the first information is a 1-bit indication information used to indicate whether the remaining energy / charge is higher than a first energy threshold. For example, setting the first information to a first value (1) indicates that the remaining energy / charge is higher than the first energy threshold, and setting the first information to a second value (0) indicates that the remaining energy / charge is lower than the first energy threshold. For example, if the first energy threshold is an absolute value, setting the first information to a first value indicates that the remaining energy / charge is higher than the absolute value, and setting the first information to a second value indicates that the remaining energy / charge is lower than the absolute value. For example, if the first energy threshold is an absolute value range, setting the first information to a first value indicates that the remaining energy / charge is within the absolute value range, and setting the first information to a second value indicates that the remaining energy / charge is not within the absolute value range. For example, if the first energy threshold is a proportional value, setting the first information to a first value indicates that the remaining energy / charge is higher than the proportional value (the proportion relative to full charge), and setting the first information to a second value indicates that the remaining energy / charge is lower than the proportional value. For example, if the first energy threshold is a proportional value range, the first information is set to a first value to indicate that the remaining energy / power is within that proportional value range, and the first information is set to a second value to indicate that the remaining energy / power is not within that proportional value range.

[0201] For example, if the first information is omitted, it is used to indicate that the remaining energy / power of the first device is higher than the first energy threshold, or to indicate that the remaining energy / power of the first device is lower than the first energy threshold.

[0202] In some embodiments, the first information is used to indicate whether the first device can complete the transmission of the first message.

[0203] For example, in the 3-step CBRA, the first information in message 1 (including a 16-bit random number) is used to indicate whether the first device can complete the transmission of the first message. The first message is message 3 (including the identifier of the first device). For example, the first device identifier can be a device identifier, such as an identifier assigned by the EPC or the core network.

[0204] For example, in the 3-step CBRA, the first information in message 3 is used to indicate whether the first device can complete the transmission of the first message. The first message is a response message to the second command. The second command is a specific command, such as a read command, a write command, a kill command, or a disable command. In short, the second command is a specific command.

[0205] For example, the first information in message 1 of the CFRA (including the identifier of the first device and / or a 16-bit random number) is used to indicate whether the first device can complete the transmission of the first message. The first message is a response message to the second command. The second command is a specific command, such as a read command, a write command, a kill command, or a disable command. In short, the second command is a specific command.

[0206] For example, the first information in message 1 of the 2-step CBRA (including the identifier of the first device and / or a 16-bit random number) is used to indicate whether the first device can complete the transmission of the first message. The first message is message 1 in the 2-step CBRA, that is, it indicates whether the first device can complete the retransmission of message 1, for example, to re-access and retransmit message 1 when contention resolution fails. Alternatively, the first message can be a response message to a second command. The second command is a specific command, such as a read command, a write command, a kill command, or a disable command. In short, the second command is a specific command.

[0207] For example, in a segmented D2R transmission (transmission from a first device to a second device), the first information is used to indicate whether the first device can complete the transmission of the first message. The first message represents the remaining D2R segments. For instance, in response to a first command, the first response of the first device needs to be segmented. In the first segment, the first information indicates whether the first device can complete the transmission of the remaining D2R segments (the remaining segments after subtracting the first segment from the first response). Similarly, in the second segment, the first information indicates whether the first device can complete the transmission of the remaining D2R segments (the remaining segments after subtracting the first and second segments from the first response), that is, whether the transmission of the remaining data can be completed.

[0208] For example, the first information is set to a first value to indicate that the first device can complete the transmission of the first message; the first information is set to a second value to indicate that the first device cannot complete the transmission of the first message. If the first information is omitted, it is used to indicate that the first device can complete the transmission of the first message, or to indicate that the first device cannot complete the transmission of the first message.

[0209] This disclosure also proposes an apparatus (also referred to as a communication device, etc.) for implementing any of the above methods. For example, an apparatus is proposed that includes units or modules for implementing the steps performed by the terminal in any of the above methods. Furthermore, another apparatus is proposed that includes units or modules for implementing the steps performed by a network device (e.g., an access network device, a core network functional node, a core network device, etc.) in any of the above methods.

[0210] It should be understood that the division of units or modules in the above device is only a logical functional division. In actual implementation, they can be fully or partially integrated into a single physical entity, or they can be physically separated. Furthermore, the units or modules in the device can be implemented by a processor calling software: for example, the device includes a processor connected to a memory containing instructions. The processor calls the instructions stored in the memory to implement any of the above methods or to implement the functions of the units or modules in the above device. The processor can be, for example, a general-purpose processor, such as a Central Processing Unit (CPU) or a microprocessor, and the memory can be internal or external to the device. Alternatively, the units or modules in the device can be implemented in the form of hardware circuits. The functionality of some or all of the units or modules can be achieved through the design of these hardware circuits, which can be understood as one or more processors. For example, in one implementation, the hardware circuit is an application-specific integrated circuit (ASIC). The functionality of some or all of the units or modules is achieved through the design of the logical relationships between the components within the circuit. In another implementation, the hardware circuit can be implemented using a programmable logic device (PLD). Taking a field-programmable gate array (FPGA) as an example, it can include a large number of logic gates. The connection relationships between the logic gates are configured through configuration files, thereby achieving the functionality of some or all of the units or modules. All units or modules of the above device can be implemented entirely through processor-called software, entirely through hardware circuits, or partially through processor-called software with the remaining parts implemented through hardware circuits.

[0211] In this embodiment, the processor is a circuit with signal processing capabilities. In one implementation, the processor can be a circuit with instruction read and execute capabilities, such as a Central Processing Unit (CPU), a microprocessor, a graphics processing unit (GPU) (which can be understood as a microprocessor), or a digital signal processor (DSP). In another implementation, the processor can implement certain functions through the logical relationships of hardware circuits. The logical relationships of the aforementioned hardware circuits are fixed or reconfigurable. For example, the processor is a hardware circuit implemented using an application-specific integrated circuit (ASIC) or a programmable logic device (PLD), such as an FPGA. In a reconfigurable hardware circuit, the process of the processor loading a configuration document and configuring the hardware circuit can be understood as the process of the processor loading instructions to implement the functions of some or all of the above units or modules. Furthermore, it can also be a hardware circuit designed for artificial intelligence, which can be understood as an ASIC, such as a Neural Network Processing Unit (NPU), a Tensor Processing Unit (TPU), or a Deep Learning Processing Unit (DPU).
