[0151] As shown in Figure 1a or Figure 1b, the communication system 100 includes a first device 101 and a network device 102.

[0152] In some embodiments, the first device 101 may be an Ambient-IoT device, or an Ambient-IoT terminal, or simply a Device. The first device 101 supports ambient power, is powered by energy harvesting, and has no battery or limited energy storage capacity (e.g., using capacitors).

[0153] The first device 101 can have features such as low memory, low processing power, low power consumption, small data transmission and massive deployment. It can be maintenance-free and has a long service life. For example, the service life of the first device 101 can exceed 10 years.

[0155] Device 1 or Device A: Cannot perform independent signal generation or amplification. Device 1 can communicate using backscattering and does not have the ability to amplify downlink (DL) signals and / or uplink (UL) signals.

[0156] Device 2a or Device B: It has energy storage capabilities but cannot generate signals independently. Device 2a can communicate using backscattering, and its stored energy can be used to amplify reflected signals, DL signals, or UL signals.

[0157] Device 2b or Device C: It has energy storage capabilities and can generate signals independently, such as a radio frequency (RF) component that actively transmits signals.

[0158] In some embodiments, the first device 101 may satisfy the following characteristics:

[0159] The peak power consumption is approximately 1 microwatt (μW), and it has an energy storage function. The initial sampling frequency offset (SFO) is as high as 10X ppm.

[0160] Peak power consumption ≤ several hundred μW, with energy storage function, SFO up to 10X ppm, and the device has DL signal and / or UL signal amplification functions. The UL signal transmission of this device can be generated internally or backscattered on an externally provided carrier. X can be determined by a protocol.

[0161] In some embodiments, network device 102 may include one or more network nodes. To support data transmission for Ambient-IoT devices, network device 102 may implement one or more of the following functions:

[0162] Energy Source (ES) Function: Provides energy to the first device 101, which can be used in devices 2a and 2b;

[0163] Downlink Transmission (DT) function: Triggers uplink transmission of the first device 101 by sending indication information.

[0164] Continuous Wave (CW) Excitation Function: Provides the electromagnetic wave required for backscattering to the first device 101, which can be used by devices 1 and 2a to achieve uplink transmission via backscattered CW. CW is actually a type of energy storage (ES), and the first device 101 can receive CW and store energy.

[0165] Uplink Receiver (UR) function: Receives uplink information backscattered by the first device 101, or receives uplink information actively transmitted by the first device 101.

[0166] In some embodiments, a network device 102 may simultaneously implement multiple or all of the above-mentioned functions; alternatively, the network device 102 may include multiple network nodes, each of which implements one of the functions. The network node implementing each function may be a user equipment (UE), a repeater, or a base station, etc. When each network node implements a function, the network can coordinate the behavior of different nodes.

[0167] In some embodiments, the network device may include at least one of an access network device and a core network device.

[0168] Optionally, the access network device may be a node or device that connects a terminal to a wireless network. The access network device may include, but is not limited to, at least one of the following in a 5G communication system: base station, evolved NodeB (eNB), next generation eNB (ng-eNB), next generation NodeB (gNB), node B (NB), home node B (HNB), home evolved nodeB (HeNB), radio backhaul device, radio network controller (RNC), base station controller (BSC), base transceiver station (BTS), base band unit (BBU), mobile switching center, base station in a 6G communication system, open RAN, cloud RAN, base station in other communication systems, and access node in a wireless fidelity (WiFi) system.

[0169] Optionally, the access network equipment can be composed of a central unit (CU) and a distributed unit (DU). The CU can also be called a control unit. By adopting the CU-DU structure, the protocol layer of the access network equipment can be separated. 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, which is centrally controlled by the CU. However, this is not the only option.

[0170] Optionally, a core network device can be a single device comprising one or more network elements, or it can be multiple devices or a group of devices, each comprising all or part of one or more network elements. Network elements can be virtual or physical. For example, the core network includes at least one of the Evolved Packet Core (EPC), 5G Core Network (5GCN), and Next Generation Core (NGC). Alternatively, a core network device refers to a network element with a specific function, such as an Access Management Function (AMF) or a Service Management Function (SMF).

[0171] As shown in Figure 1c, the communication system 100 includes a first device 101, a network device 102, and an intermediate node 103.

[0172] In some embodiments, the first device 101 and the network device 102 can be referred to the description of the foregoing embodiments, and will not be repeated here. The first device 101 and the network device 102 can be directly connected, and the first device 101 and the network device 102 can directly receive and transmit DL and UL data.

[0173] Alternatively, the first device 101 and the network device 102 transmit data through an intermediate node 103. The first device 101 and the network device 102 indirectly receive and transmit DL and UL data, with the intermediate node 103 forwarding the data.

[0174] In some embodiments, the intermediate node 103 may be a relay, repeater, integrated access backhaul (IAB), or UE.

[0175] In some embodiments, the UE includes, but is not limited to, at least one of the following: mobile phone, wearable device, Internet of Things device, car with communication function, smart car, tablet computer, computer with wireless transceiver function, virtual reality (VR) terminal device, augmented reality (AR) terminal device, wireless terminal device in industrial control, wireless terminal device in self-driving, wireless terminal device in remote medical surgery, wireless terminal device in smart grid, wireless terminal device in transportation safety, wireless terminal device in smart city, and wireless terminal device in smart home.

[0176] As shown in Figures 1d to 1e, the communication system 100 includes a first device 101, a network device 102, and an assisting node 104.

[0177] In some embodiments, the first device 101 and the network device 102 can be referred to the description of the foregoing embodiments, and will not be repeated here.

[0178] In some embodiments, the first device 101 and the network device 102 directly receive or transmit data in DL or UL; then there is an auxiliary node 104 on UL or DL, which is responsible for receiving or sending UL or receiving DL data.

[0179] In some embodiments, the auxiliary node 104 may be a relay, repeater, IAB, or UE. The UE can be found in the description of the foregoing embodiments, and will not be repeated here.

[0180] As shown in Figure 1f, the communication system 100 includes a first device 101 and a UE 105.

[0181] In some embodiments, the first device 101 and UE 105 can be referred to the description of the foregoing embodiments, which will not be repeated here.

[0182] In some embodiments, the first device 101 and the UE 105 directly receive and transmit DL and UL data; the UE 105 is responsible for collecting data and forwarding the collected data to the network side, such as the network device 102.

[0183] In some embodiments, communication between the first device 101 and the network device 102, such as communication based on the two topologies of Figures 1a to 1c, can utilize spectrum resources in three forms: in-band, guard band, and stand-alone. In-band uses normal NR communication DL and / or UL spectrum resources, such as the spectrum resources used for DL / UL communication between the base station and other UEs (Figure 1b), or the spectrum resources for DL / UL communication between the UE and the base station (Figure 1c). Guard band uses the spectrum resources of the guard band of normal NR communication DL and / or UL spectrum. Stand-alone uses spectrum resources unrelated to NR communication.

[0184] In some embodiments, the number of devices or nodes in Figures 1a to 1f is only illustrative; in actual applications, multiple devices or nodes may be used.

[0185] In some embodiments, the technical solutions of this disclosure can be applied to the Open RAN architecture. In this case, the interfaces between or within access network devices involved in the embodiments of this disclosure can be transformed into internal interfaces of Open RAN. The processes and information interactions between these internal interfaces can be implemented by software or programs.

[0186] It is understood that the communication system described in this disclosure is for the purpose of more clearly illustrating the technical solutions of this disclosure, and does not constitute a limitation on the technical solutions provided in this disclosure. As those skilled in the art will know, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions provided in this disclosure are also applicable to similar technical problems.

[0187] The following embodiments of this disclosure can be applied to the communication system 100 shown in Figures 1a to 1f, or to a portion thereof, but are not limited thereto.

[0188] The entities shown in Figures 1a to 1f are examples. The communication system may include all or some of the entities in Figures 1a to 1f, or it may include other entities other than those in Figures 1a to 1f. The number and form of each entity are arbitrary. The connection relationship between the entities is illustrative. The entities may not be connected to each other or may be connected in any way. The connection may be direct or indirect, wired or wireless.

[0189] 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 processing 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).

[0190] To meet the growing demands of vertical industries, existing Low Power Wide Area (LPMA) technologies, such as Machine Type Communication (MTC), Narrow Band Internet of Things (NB-IoT), and Reduced Capability (RedCap), can achieve low cost, low power consumption, and massive connectivity. However, they still cannot address the following needs: First, devices powered by traditional batteries are unsuitable, for example, in 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); and finally, ultra-low complexity, very small device size or form factor (e.g., thickness in millimeters), and longer lifespan are required. IoT devices that support ambient power or environmentally powered systems can meet these needs.

[0191] Low-power IoT communication chips, such as Bluetooth Low Energy (BLE), Long Range Radio (LoRa), or NB-IoT, consume tens or even hundreds of milliwatts of power for transmission and reception. However, as described in the preceding embodiments, environmental energy harvesting yields only microwatts of energy. Harvesting energy from the environment to power sensing nodes such as the first device 101 for data transmission and wireless communication requires wireless communication technologies that can reduce communication power consumption to tens or even less than ten microwatts.

[0192] Backscatter communication is an extremely low-power modulation and transmission technology that utilizes the principle of backscattering radio frequency signals, serving as a means to achieve the Internet of Things (IoT). In backscatter communication, because a portion of the radio frequency signal, such as electromagnetic waves, is reflected when it reaches the surface of an object, a passive node, such as the first device 101, adjusts the matching between its receiving antenna and impedance according to the information to be transmitted, enhancing the reflection of the incident radio frequency signal. It then modulates the sensed data it acquires onto the reflected signal, completing the data transmission. Compared to other communication technologies, backscatter communication does not require complex radio frequency structures, reducing the use of components 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.

[0193] In a Radio Frequency Identification (RFID) system using backscatter communication, as shown in Figure 1g, the receiver sends a radio frequency excitation signal to activate a passive node. The receiver, if an RFID reader, corresponds to network device 102; the passive node, if an RFID tag, corresponds to the first device 101. 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. RFID communication suffers from the following drawbacks: the wireless signal experiences double-path fading, resulting in significant path loss, short effective communication distance, and therefore limited coverage; it requires single-channel transmission; it necessitates strict tag alignment; and it lacks power control. Therefore, it is necessary to integrate 3GPP communication technologies to improve the wireless communication performance of RFID technology in passive Internet of Things (IoT) applications.

[0194] In an RFID communication system, as shown in Figure 1h, functionally, commands are divided into three categories: tag selection, inventory, and access. Among them:

[0195] The selection commands include the Select command and the Challenge command.

[0196] Inventory commands include: Query, QueryAdjust, QueryRep, ACK, and NAK.

[0197] Access commands include: a random number request (Req_RN) command, a read command, a write command, a kill command, and a lock command; optionally, they may also include: an access command, a block write command, and a block erase command.

[0198] Referring to the disk storage and retrieval example shown in Figure 1i, examples of command application in disk storage and retrieval can include:

[0199] (1) After receiving a valid Query command, each tag that meets the set criteria and is selected generates a random number. Each tag with a random number of zero will generate an echo, such as sending back a temporary password RN16, which is a 16-bit random number, and will move to the Reply state; other tags can change certain attributes and flags to exit the group of tags with zero, which helps to reduce duplicate identification.

[0200] (2) After receiving a valid QueryAdjust command, each tag generates a new random number, and other behaviors are the same as the Query command.

[0201] (3) After a tag receives a valid QueryRep command, the original random number of each tag in the tag group is decremented by one, and other behaviors are the same as the Query command.

[0202] (4) Only unique tags can receive a valid ACK command. Upon receiving the ACK command, the tag will send back the contents of the EPC area according to the Electronic Product Code (EPC) communication protocol. The ACK command can use either RN16 or Handle, where Handle is a temporary 16-bit random number representing the tag's identity.

[0203] (5) After receiving a valid NAK command, tags in the Ready and Killed states retain their original states, while tags in other states transition to the Arbitrate state. The different states of a tag are shown in Figure 1h.

[0204] Specifically, based on RN16, the identification and access activation operations for a specific tag can be completed. After obtaining the EPC, the network side identifies a certain tag. Before initiating the access command operation for that tag, the network side requests a new random value, Handle, from the tag. Subsequent communication uses the Handle to identify the tag.

[0205] Furthermore, RFID communication conforms to the half-duplex EPC protocol, allowing one reader or one tag to send a signal in a single transmission. The reader and tag do not send signals simultaneously; different tags operate serially. In Ambient IoT, concurrent communication needs to be considered, where multiple tags and the network side perform one-to-one operations simultaneously, such as access commands.

[0206] To improve communication performance and effectively schedule IoT devices in the environment, embodiments of this disclosure provide a communication method.

[0207] Figure 2a is an interactive schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 2a, the present disclosure relates to a communication method, which includes:

[0208] In step S2101, the first device 101 sends the first information to the network device 102.

[0209] In some embodiments, the first device 101 may be an environmental IoT device or an electronic tag in RFID. The network device 102 may be a base station or an intermediate node, and may be used to implement one or more of the following functions: ES function, DT function, CW incentive function, and UR function.

[0210] In some embodiments, network device 102 receives the first information.

[0211] In some embodiments, the first information includes information about the network device 102 performing device control, or auxiliary parameters.

[0212] Optionally, network device 102 performing device control may include at least one of the following: network device 102 performing scheduling, network device 102 performing resource configuration or resource allocation.

[0213] Optionally, the information used by the network device 102 to perform device control may include different types. For example, the first information may include auxiliary parameters of different aspects of the first device 101, which are used to assist the network device 102 in performing device control, including but not limited to: energy, scheduling parameters expected by the first device 101, resource allocation parameters expected by the first device 101, etc.

[0214] In some embodiments, the first device 101 may send the first information by sending an uplink (UL) command. For example, the first device 101 may report auxiliary parameters to the network device 102 by sending an UL command.

[0215] In a first possible implementation, the first information includes at least one of the following:

[0216] First duration;

[0217] Frequency information.

[0218] Optionally, the first information may include information related to the first duration.

[0219] Optionally, the first information may include information related to frequency information.

[0220] Optionally, the first duration is the duration during which the first device 101 does not expect to communicate with the network device 102. This communication can be uplink communication or downlink communication. For example, the first duration is the duration during which the first device 101 does not expect to send uplink information such as UL commands to the network device 102, and / or, the first duration is the duration during which the first device 101 does not expect to receive downlink (DL) information such as DL commands from the network device 102.

[0221] Optionally, the first duration is relative time information, for example, the start time of the first duration is the sending time of the first message.

[0222] Optionally, the frequency information is the frequency information that the first device 101 expects to communicate with the network device 102 for the next time, and the next communication is the communication after the first device 101 sends the first information. This communication can be uplink transmission or downlink reception.

[0223] In one example, before each uplink transmission by the first device 101, the network device 102 allocates resources for that uplink transmission to the first device 101 via DL signaling or DL ​​commands. The first device 101 then performs the uplink transmission based on the configuration configured by the DL signaling. The allocation of uplink transmission resources may include frequency information or time information for uplink transmission.

[0224] In this example, taking the current communication (denoted as the Nth) between the first device 101 and the network device 102 as an example where the first device 101 sends the first information, the next communication could refer to the downlink reception following this communication. For example, the network device 102 allocates resources for the N+1th uplink transmission of the first device 101 by sending DL signaling in the N+1th downlink transmission, and the first device 101 receives the downlink information, which is equivalent to receiving the DL signaling. Alternatively, in this example, the next communication could refer to the uplink transmission following this communication, such as the N+1th uplink information such as a UL command sent by the first device 101.

[0225] In some embodiments, the frequency information is a first frequency information that the first device 101 expects for the next reception of downlink information (such as a DL command), or a second frequency information that the first device 101 expects for the next transmission of uplink information (such as a UL command).

[0226] For example, in conjunction with the above example, the first device 101 may report first frequency information and / or second frequency information in the first information.

[0227] In some embodiments, the frequency information includes one of the following:

[0228] Channel number;

[0229] Circular shift value.

[0230] Optionally, the channel number can be an absolute channel number or a signal identifier, used to indicate the sub-channel for uplink transmission or downlink reception. For example, referring to RFID-related protocols, the system bandwidth is 5MHz, with each 250kHz segment representing a sub-channel, totaling 20 sub-channels. These 20 sub-channels are numbered 0 to 19 from low frequency to high frequency. The first device 101 reports the channel identifiers it supports, such as reporting the channel number corresponding to the first frequency information and the channel number corresponding to the second frequency information.

[0231] Optionally, the cyclic shift value reported by the first device 101 is used to determine the channel number expected by the first device 101 based on the reference channel number. Examples are as follows:

[0232] In one example, when the frequency information is the first frequency information, the channel number for the next downlink information reception is (n+k)mod M, where n is the channel number for transmitting the first information, k represents the cyclic shift value, and M represents the total number of channels. Mod represents the modulo operation.

[0233] In this example, the expected or suggested downlink reception channel number for the first device 101 is determined based on the cyclic shift value k and the current uplink transmission channel number n. For example, referring to the description of the foregoing embodiment, if the current uplink transmission is the Nth communication, the channel number for the (N+1)th downlink transmission by network device 102 or the downlink reception by the first device 101 is determined based on k and the channel number n of the Nth uplink transmission. Here, M can be equal to 20.

[0234] In another example, when the frequency information is the second frequency information, the channel number where the next uplink information is transmitted is (n+k)mod M, where n is the channel number of the downlink information received after the first information is transmitted and before the next uplink information is transmitted, k represents the cyclic shift value, and M represents the total number of channels.

[0235] In this example, the channel number for the next uplink transmission expected or suggested by the first device 101 is determined based on the cyclic shift value k and the channel number n of the most recent downlink reception after the current uplink transmission. For example, referring to the description of the foregoing embodiment, if the current uplink transmission is the Nth communication, the channel number for the N+1th uplink transmission is determined based on k and the channel number n of the (N+1)th downlink transmission of the network device 102. Here, M can be equal to 20.

[0236] In the second possible implementation, the first information includes at least one of the following:

[0237] Indication information used to indicate that the first device 101 needs to acquire energy;

[0238] The first device 101 is expected to acquire energy for a second duration.

[0239] Optionally, the indication information may occupy one or more bits, and different bit values ​​of the indication information may indicate whether the first device 101 needs to acquire energy.

[0240] Optionally, the first information may include information related to the second duration.

[0241] Optionally, the first device 101 can indicate the need to acquire energy and the duration for which energy acquisition is required by reporting a second duration. Alternatively, the first device 101 can report the second duration simultaneously when reporting the indication information. The second duration represents the length of time the first device 101 has reserved or the length of time required to collect energy.

[0242] In some embodiments, the second duration may be defined by a protocol or agreed upon in advance with network device 102. For example, the second duration may be indicated in advance by network device 102 to first device 101, or reported in advance by first device 101 to network device 102.

[0243] In a third possible implementation, the first information may include at least one parameter from the first possible implementation and at least one parameter from the second possible implementation. For example, the first information includes at least one of the following:

[0244] First duration;

[0245] Frequency information;

[0246] Instruction information;

[0247] Second duration.

[0248] Optionally, the first information may include information related to the first duration.

[0249] Optionally, the first information may include information related to frequency information.

[0250] Optionally, the first information may include information related to the second duration.

[0251] In some embodiments, the first information may include energy information of the first device 101. For example:

[0252] In a fourth possible implementation, the first information may include the remaining energy of the first device 101.

[0253] Optionally, the first information may include remaining energy or energy-related information.

[0254] Optionally, the first device 101 can directly report the remaining power, or indirectly report the remaining power by reporting the duration of the remaining power.

[0255] In some embodiments, the first information may include at least one of the following: a first duration, frequency information, and remaining energy. Alternatively, the first information may include at least one of the following: indication information, a second duration, and remaining energy.

[0256] Step S2102: Start the timer.

[0257] In some embodiments, the runtime of the timer (T1) is a first duration.

[0258] In some embodiments, the first device 101 may start a timer T1 after sending the first information; for example, step S2102 may be performed after sending a UL command. During the operation of the timer, or before the timer expires, the first device 101 does not expect to communicate with the network device 102, such as not expecting to receive any DL commands and / or not expecting to send any UL commands.

[0259] In some embodiments, network device 102 may start timer T1 after receiving the first information, such as performing step S2102 after receiving a UL command. Specifically, network device 102 may start the timer only for the first device 101 that sent the first information, so that it does not communicate with the first device 101 during the timer's operation.

[0260] In some embodiments, the first device 101 and the network device 102 agree on a first duration by starting a timer. In this case, the first duration may not be separately indicated in the first information reported by the first device 101. For example, the first information includes frequency information.

[0261] In step S2103, during the runtime of the timer, the first device 101 and the network device 102 do not communicate.

[0262] In some embodiments, the lack of communication between the first device 101 and the network device 102 may include one of the following:

[0263] The first device 101 does not send uplink information (such as UL commands) to the network device 102, and the network device 102 does not receive the uplink information;

[0264] Network device 102 does not send downlink information (such as DL commands) to the first device 101, and the first device 101 does not receive the downlink information.

[0265] In some embodiments, during the operation of the timer T1, the first device 101 may acquire energy, such as by receiving a power supply signal or power supply information to replenish power, or the first device 101 may perform a determined operation based on its own equipment, or may not perform any operation to achieve energy saving.

[0266] In some embodiments, during the operation of the timer T1, the network device 102 does not send any downlink commands to the first device 101.

[0267] In some examples, the power supply signal or power supply information may be provided by network device 102 with ES functionality, by intermediate node with ES functionality, or by a separate ES node. During the operation of the timer, network device 102 does not send downlink commands, but can provide a power supply signal or power supply information for the first device 101 to collect and acquire energy.

[0268] In step S2104, network device 102 sends second information to first device 101.

[0269] In some embodiments, the second information is used to indicate a third duration for the first device to harvest energy, the third duration being the same as or different from the second duration.

[0270] Optionally, the third duration may be greater than or equal to the second duration.

[0271] Optionally, when the first device 101 reports the second duration based on the protocol definition or the agreement with the network device 102, the third duration can be equal to the second duration, and the network device 102 instructs the first device 101 to perform energy collection for the corresponding duration through the second information.

[0272] In some embodiments, step S2104 may be performed when the first device 101 reports indication information and / or a second duration. For example, the first information includes indication information, or the first information includes a second duration, or the first information includes both indication information and a second duration.

[0273] In some embodiments, after steps S2102 to S2103, network device 102 executes step S2104, instructing the first device 101 to obtain energy.

[0274] In some embodiments, the first device 101 executes step S2105 after receiving the second information.

[0275] In step S2105, the first device 101 acquires energy within the third time period.

[0276] In some embodiments, the first device 101 may obtain energy by receiving a power supply signal or power supply information within a third time period.

[0277] In some embodiments, the first device 101 does not receive downlink information, such as DL commands, sent by the network device 102 within a third time period.

[0278] In some embodiments, the start time of the third duration is the time when the first device 101 receives the second information. For example, from the start of sending the second information, the network device 102 does not send downlink commands to the first device 101 during the third duration; from the start of receiving the second information, the first device 101 does not receive downlink commands sent by the network device 102 during the third duration.

[0279] In some embodiments, the names of information, etc., are not limited to the names described in the embodiments. Terms such as "signal", "message", "signaling", "report", "configuration", "indication", "instruction", "command", "channel", "parameter", "domain", and "field" can be used interchangeably.

[0285] The method involved in the embodiments of this disclosure may include at least one of steps S2101 to S2105. For example, the method includes step S2101, or the method includes steps S2101 to S2103, or the method includes steps S2101, S2104 to S2105, or the method includes steps S2101 to S2105.

[0286] In some embodiments, at least one of steps S2104 and S2105 may be omitted, and may be replaced by one or more steps in different embodiments. For example, the method may include step S2101 or steps S2102 to S2103.

[0287] In some embodiments, at least one of steps S2102 and S2103 may be omitted, and may be replaced by one or more steps in different embodiments. For example, the method includes steps S2101, S2104 to S2105.

[0288] In some embodiments, other alternative implementations may be described before or after the specification corresponding to FIG2a.

[0289] In this embodiment of the disclosure, network device 102 can allocate and schedule resources for the first device 101 based on the first information provided by the first device 101. The first device 101 reports its own needs by sending the first information. For example, it may need to collect a power signal after an uplink transmission; or the frequency offset difference between downlink reception and uplink transmission should not be too large; or the first device 101 needs to conserve energy during communication and does not expect to receive DL commands or UL transmissions for a certain period. The first information helps network device 102 to schedule resources based on the needs or expectations of the first device 101, thereby optimizing the communication performance of the first device 101.

[0290] Figure 2b is an interactive schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 2b, the present disclosure relates to a communication method, which includes:

[0291] In step S2201, the first device 101 sends the first information to the network device 102.

[0292] In some embodiments, the first information includes energy information of the first device 101, such as remaining energy. Alternatively, the implementation of step S2201 can be found in the implementation of step S2101 in FIG2a, and will not be repeated here.

[0293] In step S2202, network device 102 sends third information to first device 101.

[0294] In some embodiments, the third information is used to instruct the first device 101 not to listen to downlink information for a fourth duration.

[0295] Optionally, the fourth duration is used to indicate that the first device 101 does not need to listen to the network side's duration information.

[0296] Optionally, the fourth duration can be the same as the second or third duration in the foregoing embodiments.

[0297] In some embodiments, the third information may be sent separately from, synchronously with, or sent using the same signaling as the second information in the foregoing embodiments.

[0298] In some embodiments, after receiving the third information, the first device 101 may execute step S2103.

[0299] In step S2203, the first device 101 does not listen to the downlink information sent by the network device 102 during the fourth time period.

[0396] In some embodiments, other alternative implementations may be described before or after the specification corresponding to FIG4e.

[0397] This disclosure provides a method for resource allocation and scheduling of tags based on auxiliary parameters provided by the tags during tag communication. In this embodiment, the tag or terminal corresponds to the first device 101 in the aforementioned embodiment, and the network side corresponds to the network device 102 in the aforementioned embodiment. To facilitate understanding of this disclosure, some examples are listed below:

[0398] Example 1:

[0399] The terminal sends a UL command, which contains the following information:

[0400] Optional example (Option 1): Time information.

[0401] The time information is relative; that is, a timer T1 is started from the moment the tag sends the UL command. Before the timer expires, the tag does not expect to receive any DL commands and / or send any UL commands. During the operation of T1, the tag may receive power supply information to replenish power, or it may do nothing, depending on the tag implementation. For the network side, upon receiving the UL command, the network side starts a timer for that tag. During the timer's operation, no downlink commands are sent for that tag.

[0402] Option 2: Frequency Information 1.

[0403] Frequency information 1 is used to suggest the preferred frequency for receiving the next DL command. Frequency information 1 is an absolute channel number. For example, in the Chinese RFID domestic standard, the system bandwidth is 5MHz, with one sub-channel at 250kHz, for a total of 20 sub-channels. Sub-channels are numbered from 0 to 19, from low to high frequency. Optionally, frequency information 1 can also be a cyclic shift value, such as k. In this case, the channel number for receiving the next DL command is (the channel number n+k from which the current UL command was sent) modulo the total number of sub-channels, for example, 20.

[0404] Option 3: Frequency Information 2.

[0405] Frequency information 2 is used to suggest the frequency for the next UL command to be sent, based on the tag's preference. Frequency information 2 is an absolute channel number. For example, in the Chinese RFID domestic standard, the system bandwidth is 5MHz, with each subchannel at 250kHz, for a total of 20 subchannels. Subchannels are numbered from 0 to 19, from low to high frequency. Optionally, frequency information 2 can also be a cyclic shift value, such as k. In this case, the channel number for the next UL command transmission is (the channel number of the received DL signaling n+k) modulo the total number of subchannels, for example, 20. The transmission of UL signaling here is based on the resource allocation in the received DL signaling.

[0406] Example 2:

[0407] The tag sends a notification to the network, indicating that it needs to collect energy. The tag can also specify the duration of the scheduled collection, which can be agreed upon or predetermined. For example, a predetermined duration could be indicated by the network to the tag, or by the tag to the network.

[0408] The network side replies with a tag, indicating that the tag can be used to collect the available time length.

[0409] The timeframe begins from the moment the tag receives the instruction; within this timeframe, the network side does not send downlink commands to the tag.

[0410] Example 3:

[0411] The network side sends a time length information to the tag. This time length information indicates that the tag does not need to listen to the network side within this time period. This time length can begin from the receipt of the DL command carrying this time length.

[0412] In this embodiment, resource allocation and scheduling for tags are based on auxiliary parameters provided by the tags. For example, after a UL transmission, a tag may need to collect a power supply signal; or the frequency offset difference between DL and UL transmissions may not be too large; or the tag may conserve energy during communication and may not expect to receive DL reception or UL transmissions for a certain period. This auxiliary information helps the network side schedule tags according to their needs, thereby optimizing the tag's communication performance.

[0413] This disclosure also provides an apparatus for implementing any of the above methods. For example, an apparatus is provided that includes units or modules for implementing the steps performed by the terminal in any of the above methods. Alternatively, another apparatus is provided 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.

[0414] 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.

[0415] 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).
