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

[0243] The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG1 , or a portion thereof, but are not limited thereto. The entities shown in FIG1 are illustrative only. The communication system may include all or part of the entities shown in FIG1 , or may include other entities outside of FIG1 . The number and form of the entities are arbitrary, and the entities may be physical or virtual. The connection relationships between the entities are illustrative only.

[0244] The embodiments of the present disclosure 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 (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (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 utilizing other communication methods, and next-generation systems based on and extending these methods. Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0245] In today's IoT networks, traditional IoT devices are often powered by conventional batteries with limited lifespans, negatively impacting the user experience. The astronomical growth of IoT networks, coupled with the proliferation of IoT devices, has pushed maintenance expenses, including labor and battery costs, to a whole new level. Billions of conventional batteries are discarded annually, with only a small fraction effectively recycled, resulting in detrimental impacts on Earth's ecosystems. Maintaining IoT network operations and replacing batteries can be extremely challenging in extreme environmental conditions. Consequently, research is underway to develop battery-free IoT communications that will improve network performance and sustainability, while expanding their application scenarios. Furthermore, battery-free communications are environmentally friendly and safer for children and the elderly. By eliminating traditional batteries, device size and cost can be significantly reduced, paving the way for a variety of new applications. IoT powered by ambient power is a promising technology that can address these needs.

[0246] In some embodiments, backscatter communication is one of the key technologies for building a passive Internet of Things.

[0247] Backscatter communication is an extremely low-power modulation and transmission technology designed using the principle of RF signal backscattering. Since RF signals are partially reflected when they reach surfaces, the transmitting device can adjust the matching between the receiving antenna and the impedance according to the intended transmission information to enhance the transmission of the incident RF signal. The device then modulates the acquired sensor data onto the reflected signal to complete the data transmission.

[0248] Compared with other communication technologies, backscatter communication can be implemented without complex RF structure, which can reduce the use of devices such as power amplifiers, high-precision crystal oscillators, duplexers, high-precision filters, etc. It also does not require complex baseband processing processes, which can simplify the design of terminal equipment and reduce equipment costs.

[0249] Backscatter communication is widely used in Radio Frequency Identification (RFID) systems. A receiver (such as an RFID reader) can send a radio frequency signal to activate a passive node (such as an RFID tag). The passive node then uses backscatter communication to modulate its own information onto the radio frequency signal to transmit the information. After receiving the reflected signal from the passive node, the receiver can demodulate the reflected signal to read the information.

[0250] In some embodiments, a communication process similar to that of an RFID system can be adopted to implement the communication design of an Ambient IOT system based on reflection scattering technology.

[0251] In some embodiments, the Ambient IoT system may support multiple types of Ambient IoT devices.

[0252] In some embodiments, the Ambient IOT system may support two types of Ambient IOT devices: type 1 and type 2.

[0253] Type 1 Ambient IoT devices have energy storage but lack independent signal generation and amplification, relying on backscatter for uplink transmission. Type 2 Ambient IoT devices, on the other hand, have energy storage and independent signal amplification, and their uplink transmission can be generated internally or rely on backscatter.

[0254] In some embodiments, type 2 Ambient IoT devices can be further divided into type 2a (type 2a) and type 2b (type 2b).

[0255] Type 2a Ambient IoT devices have energy storage and independent signal amplification, and their uplink transmission relies on backscattering. Type 2b Ambient IoT devices have energy storage and independent signal amplification, and their uplink transmission can be based on internally generated signals.

[0256] In some embodiments, the Ambient IOT system can support multiple network topologies.

[0257] Refer to Figure 2A, which is a network topology diagram of an Ambient IOT system according to an embodiment of the present disclosure. Taking the access network device as a base station as an example, as shown in Figure 2A, data (including uplink data and downlink data) can be directly sent and received between the Ambient IOT device and the base station.

[0258] Refer to Figure 2B, which is a network topology diagram of another Ambient IOT system according to an embodiment of the present disclosure. Taking the access network device as a base station as an example, as shown in Figure 2B, data (including uplink data and downlink data) can be indirectly sent and received between the Ambient IOT device and the base station, and the intermediate node can play the function of data forwarding between the Ambient IOT device and the base station.

[0259] It should be noted that the above are only two exemplary network topologies and do not constitute a limitation on the network topology of the Ambient IOT system.

[0260] In some embodiments, in the network topology shown in Figure 2A, for the case where the backscatter from the Ambient IoT device to the Ambient IoT reader (Device-to-Reader, D2R) and the continuous wave (Continuous Wave, CW) used for backscatter belong to the same carrier, the CW can be generated from within the network topology and sent on the downlink (Downlink) spectrum; or, the CW can be generated from within the network topology and sent on the uplink (Uplink) spectrum; or, the CW can be generated from outside the network topology and sent on the UL spectrum.

[0261] In some embodiments, terms such as "uplink", "uplink", "physical uplink", etc. can be used interchangeably, and terms such as "downlink", "downlink", "physical downlink", etc. can be used interchangeably.

[0262] In some embodiments, in the network topology shown in Figure 2B, for the case where the backscatter of D2R and the CW used for backscatter belong to the same carrier, the CW can be generated from inside the network topology (such as an intermediate node, such as a UE) and sent on the UL spectrum; or, the CW can be generated from outside the network topology and sent on the DL spectrum; or, the CW can be generated from outside the network topology and sent on the UL spectrum.

[0263] However, the transmission control topology and transmission control method of CW signals in the Ambient IoT scenario are still unclear.

[0264] FIG3 is an interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG3 , the embodiment of the present disclosure relates to a communication method, and the method includes:

[0265] Step S3101: The first communication device sends capability information to the second communication device.

[0266] In some embodiments, the first communication device is a device capable of transmitting a first signal.

[0267] In some embodiments, the first communication device may include at least one of a UE, an access network device (such as a gNB), and a core network device (such as a core network function node), but is not limited thereto. The first communication device may also be an independent first signal sending node.

[0268] That is, the first communication device may be a UE, or the first communication device may be an access network device (such as a gNB), or the first communication device may be a core network device (such as a core network function node); in more possible implementations, the first communication device may also be an independent first signal sending node.

[0270] In some embodiments, the first communication device and the Ambient IOT device belong to the same network topology; or, the first communication device and the Ambient IOT device belong to different network topologies.

[0271] It should be noted that if the first communication device is a UE and the first communication device and the Ambient IoT device belong to the same network topology, then the UE serving as the first communication device can serve as an intermediate node in the network topology. If the first communication device is a UE and the first communication device and the Ambient IoT device belong to different network topologies, then the UE serving as the first communication device is a UE located outside the topology and capable of sending the first signal.

[0272] In some embodiments, the second communication device is a device capable of controlling the transmission of the first signal.

[0273] In some embodiments, the second communication device may include at least one of a UE, an access network device (such as a gNB), and a core network device (such as a core network function node), but is not limited thereto. The second communication device may also be an independent first signal control node.

[0274] That is, the second communication device may be a UE, or the second communication device may be an access network device (such as a gNB), or the second communication device may be a core network device (such as a core network (CN) functional node); in more possible implementations, the second communication device may also be an independent first signal control node.

[0275] In some embodiments, the name of the second communication device is not limited, and may be, for example, a "first signal control device", a "second node", a "first signal control node", etc.

[0276] In some embodiments, the second communication device and the Ambient IoT device belong to the same network topology; or, the second communication device and the Ambient IoT device belong to different network topologies.

[0277] It should be noted that if the second communication device is a UE and the second communication device and the Ambient IoT device belong to the same network topology, then the UE serving as the second communication device can serve as an intermediate node in the network topology. If the second communication device is a UE and the second communication device and the Ambient IoT device belong to different network topologies, then the UE serving as the second communication device is a UE located outside the topology and capable of sending the first signal.

[0278] In some embodiments, for the network topology shown in Figure 2A, the first communication device may be a UE, and the second communication device may be a gNB; or, the first communication device may be a UE, and the second communication device may be a CN functional node; or, the first communication device may be a gNB that sends commands to the Ambient IOT device, and the second communication device may also be a gNB that sends commands to the Ambient IOT device; or, the first communication device may be a gNB that sends commands to the Ambient IOT device, and the second communication device may be a CN functional node; or, the first communication device may be a gNB outside the network topology, and the second communication device may be a CN functional node; or, the first communication device may be a gNB outside the network topology, and the second communication device may be a gNB that sends commands to the Ambient IOT device; or, the first communication device may be a CN functional node, and the second communication device may be a gNB that sends commands to the Ambient IOT device.

[0279] In some embodiments, for the network topology shown in FIG2B , the first communication device may be an intermediate node UE, and the second communication device may also be the intermediate node UE; or, the first communication device may be an intermediate node UE, and the second communication device may be a gNB that has an RRC connection with the intermediate node UE; or, the first communication device may be an intermediate node UE, and the second communication device may be a UE outside the network topology; or, the first communication device may be an intermediate node UE, and the second communication device may be a CN functional node; or, the first communication device may be a UE outside the network topology, and the second communication device may be a gNB that has an RRC connection with the intermediate node UE; or, the first communication device may be a UE outside the network topology For a UE outside the network topology, the second communication device may be the gNB to which the UE outside the network topology is currently connected; or, the first communication device may be a UE outside the network topology, and the second communication device may be a CN functional node; or, the first communication device may be a gNB that has an RRC connection with an intermediate node UE, and the second communication device may be a CN functional node; or, the first communication device may be a CN functional node, and the second communication device may be an intermediate node UE; or, the first communication device may be a CN functional node, and the second communication device may be a UE inside or outside the network topology; or, the first communication device may be a CN functional node, and the second communication device may be a gNB inside or outside the network topology.

[0280] The above is merely an exemplary combination of the first communication device and the second communication device and does not constitute a limitation to the embodiments of the present disclosure.

[0281] In some embodiments, the capability information is used to indicate that the first communications device has the capability to send the first signal.

[0282] In some embodiments, the second communication device receives capability information sent by the first communication device, where the capability information is used by the second communication device to determine whether it can control the first communication device to send the first signal.

[0283] In some embodiments, the name of the capability information is not limited, and may be, for example, "capability indication information", "capability indication", etc.

[0284] In some embodiments, the names of information, etc. are not limited to the names described in the embodiments, and terms such as "information", "message", "signal", "signaling", "report", "configuration", "indication", "instruction", "command", "channel", "parameter", "domain", "field", "symbol", "symbol", "codeword", "codebook", "codeword", "codepoint", "bit", "data", "program", and "chip" can be used interchangeably.

[0285] It should be noted that the introduction to the first signal will be described in detail below and will not be repeated here.

[0286] Step S3102: The second communication device determines, based on the capability information, that it can control the first communication device to send the first signal.

[0287] In some embodiments, the second communication device may determine that the first communication device is capable of sending the first signal based on capability information received from the first communication device, so that the second communication device determines that it can control the first communication device to send the first signal.

[0288] In some embodiments, the ambient IOT device does not need to determine whether the first communication device is capable of sending the first signal based on capability information, but can directly determine whether the first communication device is capable of sending the first signal based on itself, so as to achieve the determination that the second communication device can control the first communication device to send the first signal.

[0289] That is, the process of obtaining capability information can be decoupled from the process of determining whether the first communication device can be controlled to transmit the first signal. In some embodiments, the second communication device can determine, based on a protocol agreement, that the first communication device is capable of transmitting the first signal, so that the second communication device can determine that it can control the first communication device to transmit the first signal, without having to determine that it can control the first communication device to transmit the first signal based on capability information, but this is not limited to this approach. In short, the second communication device can determine whether it can control the first communication device to transmit the first signal through a specific method.

[0290] It should be noted that how to control the first communication device to send the first signal will be described in detail below and will not be repeated here.

[0291] In some embodiments, the first signal is used to power the Ambient IoT device, and / or the first signal is used for the Ambient IoT device to send data or signaling.

[0292] In some embodiments, the name of the first signal is not limited. For the first signal used to power the Ambient IOT device, its name is, for example, "power signal"; for the first signal used for the Ambient IOT device to send data or signaling, its name is, for example, "excitation signal", "CW signal", etc.

[0293] Step S3103: The second communication device sends first information to the first communication device.

[0294] In some embodiments, the first communication device receives first information sent by the second communication device.

[0295] In some embodiments, the manner of determining the first information may include at least one of the following: determination by a second communication device, agreement by a protocol, and determination by an Ambient IOT device.

[0296] In some embodiments, the first information may be determined by the second communication device, or the first information may be agreed upon by a protocol, or the first information may be determined by an Ambient IOT device.

[0297] In some embodiments, the above-mentioned methods of determining the first information can also be used in combination, that is, the second communication device can also jointly determine the first information based on its own implementation and protocol agreement, or the Ambient IOT device can jointly determine the first information based on its own implementation and protocol agreement, or the second communication device and the Ambient IOT device can jointly determine the first information, and so on. The embodiments of this disclosure do not limit the specific combination methods.

[0298] In some embodiments, the first information is determined by the second communication device, and the second communication device can determine the first information based on the device type of the Ambient IOT device; or, the second communication device can determine the first information based on the device capability of the Ambient IOT device; or, the second communication device can determine the first information based on the command type of the first command; or, the second communication device can determine the first information based on the command identifier of the first command, and so on.

[0299] Optionally, the second communication device may obtain the first command and determine the first information based on the command type of the first command. After determining the first information, the second communication device may inform the first communication device of the first information, so that the first communication device can control the transmission of the first signal based on the first information. The manner in which the first signal is transmitted may vary depending on the first information.

[0300] In some embodiments, the first command is a command associated with an Ambient IOT device.

[0301] For example, the first command may be a command that the Ambient IOT device is processing, or the first command may be a command previously sent to the Ambient IOT device, or the first command may be a command to be sent to the Ambient IOT device, etc., which is not limited in the embodiments of the present disclosure.

[0302] In some embodiments, the first command may include at least one of a paging command, an inventory command, and an access command, but is not limited thereto.

[0303] In some embodiments, the inventory command may include a query (Query) command, a query response (QueryRep) command, a query adjustment (QueryAdjust) command, etc., but is not limited thereto.

[0304] In some embodiments, the access command may include a write command, a read command, a disable command, etc., but is not limited thereto.

[0305] In some embodiments, different first commands correspond to different first information; or, different types of first commands correspond to different first information; or, different Ambient IOT devices correspond to different first information; or, different types of Ambient IOT devices correspond to different first information.

[0306] That is, the configuration of the first information can be based on a (per) command, a command type, an Ambient IoT device, or an Ambient IoT device type.

[0307] That is, the first information determined based on different commands may be different, or the first information determined based on different types of commands may be different, or the first information determined based on different Ambient IOT devices may be different, or the second information determined based on different types of Ambient IOT devices may be different.

[0308] In some embodiments, the first information is agreed upon in a protocol, and the second communication device may determine the first information according to the protocol.

[0309] For example, the first information may be agreed upon in the protocol, and the second communication device may directly obtain the first information agreed upon in the protocol.

[0310] Alternatively, a rule for determining the first information may be agreed upon in the protocol, and the second communication device may determine the first information according to the rule agreed upon in the protocol.

[0311] In some embodiments, the first information is determined by the Ambient IoT device, and the Ambient IoT device may determine the first information and then send the determined first information to the second communication device.

[0312] In some embodiments, the Ambient IOT device may determine the first information based on the device type of the Ambient IOT device; or, the Ambient IOT device may determine the first information based on the device capability of the Ambient IOT device; or, the Ambient IOT device may determine the first information based on the command type of the first command, and so on.

Depending on the first information, the method of transmitting the first signal may vary.

[0314] In some embodiments, the first command is a command associated with an Ambient IOT device.

[0315] For example, the first command may be a command that the Ambient IOT device is processing, or the first command may be a command previously sent to the Ambient IOT device, or the first command may be a command to be sent to the Ambient IOT device, etc., which is not limited in the embodiments of the present disclosure.

[0319] In some embodiments, different first commands correspond to different first information; or, different types of first commands correspond to different first information; or, different Ambient IOT devices correspond to different first information; or, different types of Ambient IOT devices correspond to different first information.

[0320] That is, the first information may be configured per command, per command type, per device, or per device type.

[0321] That is, the first information determined based on different commands may be different, or the first information determined based on different types of commands may be different, or the first information determined based on different Ambient IOT devices may be different, or the second information determined based on different types of Ambient IOT devices may be different.

[0322] In some embodiments, the first information is used to indicate information related to the Ambient IOT device.

[0323] In some embodiments, the name of the first information is not limited, and it can be, for example, "CW transmission control information", "signal transmission control information", "first signal transmission control information", etc.

[0324] In some embodiments, the first information includes at least one of first indication information, second indication information, third indication information, and fourth indication information.

[0325] In some embodiments, the first indication information is used to indicate command information of a first command, where the first command is a command associated with an Ambient IOT device. For an introduction to the first command, please refer to the above and will not be repeated here.

[0326] In some embodiments, the first indication information may include identification information of the first command and / or type information of the first command.

[0327] In some embodiments, the identification information of the first command is also the command identification of the first command, and the type information of the first command is also the command type of the first command, that is, the first indication information may include the command identification of the first command and / or the command type of the first command.

[0328] In some embodiments, the name of the first indication information is not limited, and it can be, for example, "Ambient IOT command information", "Ambient IOT command related information", etc.

[0329] In some embodiments, the second indication information is used to indicate device information of an Ambient IoT device.

[0330] In some embodiments, the second indication information may include identification information of the Ambient IoT device and / or type information of the Ambient IoT device.

[0331] In some embodiments, the identification information of the Ambient IOT device is also the device identification of the Ambient IOT device, and the type information of the Ambient IOT device is also the device type of the Ambient IOT device, that is, the second indication information may include the device identification of the Ambient IOT device and / or the device type of the Ambient IOT device.

[0332] In some embodiments, the name of the second indication information is not limited, and it can be, for example, "Ambient IOT device information", "Ambient IOT device related information", etc.

[0333] In some embodiments, the third indication information is used to indicate information related to the processing time of the first command.

[0334] In some embodiments, the third indication information is used by the first communications device to ensure transmission of the first signal within a processing time of the first command.

[0335] In some embodiments, the name of the third indication information is not limited, and it can be, for example, "Ambient IOT command processing time information", "Ambient IOT command processing time related information", etc.

[0336] In some embodiments, the fourth indication information is used to indicate information related to the sending time of the first signal.

[0337] In some embodiments, the fourth indication information may include at least one of a sending start time of the first signal, a sending duration of the first signal, a sending stop time of the first signal, and a sending period of the first signal.

[0338] It should be noted that any one of the sending start time, sending duration, and sending stop time of the first signal indicated by the fourth indication information can be an absolute time or a relative time. For example, the sending time of the first command is used as the reference time, and the sending time of the first command is prepended by N time slots as the time indicated by the fourth indication information.

[0339] In some embodiments, N may be any value. Alternatively, the value of N may be agreed upon by a protocol, or may be configured by a third communication device.

[0340] In some embodiments, the third communication device may include at least one of an intermediate node, an access network device, a core network device, an Ambient IOT server, and an Operation Administration and Maintenance (OAM) device, but is not limited thereto.

[0341] That is, the third communication device may be a UE, or the third communication device may be an access network device, or the third communication device may be a core network device, or the third communication device may be an Ambient IOT server, or the third communication device may be an OAM device.

[0342] In some embodiments, the third communication device and the Ambient IoT device belong to the same network topology; or, the third communication device and the Ambient IoT device belong to different network topologies.

[0343] It should be noted that if the third communication device is a UE and the third communication device and the Ambient IoT device belong to the same network topology, then the UE serving as the third communication device can serve as an intermediate node in the network topology. If the third communication device is a UE and the third communication device and the Ambient IoT device belong to different network topologies, then the UE serving as the third communication device is a UE located outside the topology and capable of sending the first signal.

[0344] It should be noted that in the Ambient IOT system, the time interval between two command transmissions (that is, the time interval between two command transmissions) can be used as a time slot, that is, the time period corresponding to the time when the last command is sent to the time when the next command is sent can be used as a time slot.

[0345] In some embodiments, terms such as "time slot", "sub-slot", "mini-slot", "frame", "radio frame", "subframe", "symbol", "symbol", "transmission time interval (TTI)" and the like can be used interchangeably.

[0346] In some embodiments, the name of the fourth indication information is not limited, and it can be, for example, "time indication information", "first signal sending time information", "signal sending indication information", etc.

[0347] In some embodiments, terms such as "time", "moment", "time point", and "time position" can be replaced with each other, and terms such as "duration", "period", "time window", "window", and "time" can be replaced with each other.

[0348] In some embodiments, the second communication device may send first signaling to the first communication device, where the first signaling includes first information.

[0349] Correspondingly, the first communication device may receive first signaling sent by the second communication device, where the first signaling includes the first information.

[0350] In some embodiments, the first signaling may reuse some signaling in related technologies.

[0351] For example, in the network topology shown in FIG2A , where the first communication device is a UE and the second communication device is a gNB or a CN functional node, the first signaling may be any one of Media Access Control (MAC) signaling, Radio Resource Control (RRC) signaling, Downlink Control Information (DCI) signaling, and Non-Access Stratum (NAS) signaling. That is, in network topology 1, if the UE serves as the first communication device and the gNB or CN functional node serves as the second communication device, the first information may be included in any one of MAC signaling, RRC signaling, DCI signaling, and NAS signaling and sent by the gNB or CN functional node to the UE.

[0352] For another example, in the network topology shown in Figure 2A , where the first communication device is a gNB (denoted as gNB1) that sends a command to an Ambient IoT device, and the second communication device is also gNB1, the first information can be independently obtained by gNB1 based on internal implementation without requiring signaling transmission. That is, in the network topology shown in Figure 2A , if gNB1 is the first communication device and gNB2 is the second communication device, the first information can be independently obtained by gNB1 based on internal implementation.

[0353] For another example, in the network topology shown in Figure 2A , where the first communication device is gNB1 and the second communication device is a CN functional node, the first signaling may be Next Generation Application Protocol (NGAP) signaling or Next Generation (NG) signaling. That is, in the network topology shown in Figure 2A , if gNB1 serves as the first communication device and the CN functional node serves as the second communication device, the first information may be included in NGAP signaling / NG signaling and sent by the CN functional node to gNB1.

[0354] For another example, in the network topology shown in Figure 2A , where the first communication device is a gNB located outside the network topology (denoted as gNB2) and the second communication device is gNB1 or a CN functional node, the first signaling may be Xn signaling, NGAP signaling, or NG signaling. That is, in the network topology shown in Figure 2A , if gNB2 serves as the first communication device and gNB1 or a CN functional node serves as the second communication device, the first information may be included in the Xn signaling, NGAP signaling, or NG signaling and sent by gNB1 or the CN functional node to gNB2.

[0355] For another example, in the network topology shown in Figure 2A , where the first communication device is a CN functional node and the second communication device is gNB1, the first signaling may be NGAP signaling or NG signaling. That is, in the network topology shown in Figure 2A , if the CN functional node serves as the first communication device and gNB1 serves as the second communication device, the first information may be included in the NGAP signaling or NG signaling and sent by gNB1 to the CN functional node.

[0356] It should be noted that, in the network topology shown in FIG2A , if other independent non-3GPP visible nodes are used as the first communication devices, the embodiment of the present disclosure does not limit the transmission process of the first information.

[0357] For example, in the network topology shown in FIG2B , where the first communication device is a UE (denoted as UE1) serving as an intermediate node and the second communication device is a gNB (denoted as gNB3) having an RRC connection with UE1 or a gNB currently connected to UE2 (denoted as gNB4), the first signaling may be any one of MAC signaling, RRC signaling, and DCI signaling. That is, in the network topology shown in FIG2B , if UE1 serves as the first communication device and gNB3 or gNB4 serves as the second communication device, the first information may be included in any one of MAC signaling, RRC signaling, and DCI signaling and sent by gNB3 or gNB4 to UE1.

[0358] For another example, in the network topology shown in FIG2B , where the first communication device is UE1 and the second communication device is a CN functional node, the first signaling may be NAS signaling. That is, in the network topology shown in FIG2B , if UE1 serves as the first communication device and the CN functional node serves as the second communication device, the first information may be included in the NAS signaling and sent by the CN functional node to UE1.

[0359] For another example, in the network topology shown in FIG2B , where the first communication device is UE1 and the second communication device is also UE1, the first information can be independently obtained by UE1 based on internal implementation without the need for signaling transmission. That is, in the network topology shown in FIG2B , if UE1 is the first communication device and UE2 is the second communication device, the first information can be independently obtained by UE1 based on internal implementation.

[0360] For another example, in the network topology shown in Figure 2B , where the first communications device is UE2 and the second communications device is gNB3 or gNB4, the first signaling may be any one of inter-UE signaling, MAC signaling, RRC signaling, and DCI signaling. That is, in the network topology shown in Figure 2B , if UE2 is the first communications device and gNB3 or gNB4 is the second communications device, the first information may be included in any one of inter-UE signaling, MAC signaling, RRC signaling, and DCI signaling and sent by gNB3 or gNB4 to UE2.

[0361] For another example, in the network topology shown in FIG2B , where the first communication device is UE2 and the second communication device is a CN functional node, the first signaling may be NAS signaling. That is, in the network topology shown in FIG2B , if UE2 serves as the first communication device and the CN functional node serves as the second communication device, the first information may be included in the NAS signaling and sent by the CN functional node to UE2.

[0362] For another example, in the network topology shown in FIG2B , where the first communication device is gNB3 and the second communication device is a CN functional node, the first signaling may be UE1 UL signaling, NGAP signaling, or NG signaling. That is, in the network topology shown in FIG2B , if gNB3 serves as the first communication device and the CN functional node serves as the second communication device, the first information may be included in the UE1 UL signaling, NGAP signaling, or NG signaling and sent by the CN functional node to gNB3.

[0363] For another example, in the network topology shown in FIG2B , where the first communication device is a CN functional node and the second communication device is gNB3 or gNB4, the first signaling may be UL NAS signaling, NGAP signaling, or NG signaling. That is, in the network topology shown in FIG2B , if the CN functional node serves as the first communication device and gNB3 or gNB4 serves as the second communication device, the first information may be included in the UL NAS signaling, NGAP signaling, or NG signaling and sent by gNB3 or gNB4 to the CN functional node.

[0364] It should be noted that, in the network topology shown in FIG2B , if other independent non-3GPP visible nodes are used as the first communication devices, the embodiment of the present disclosure does not limit the transmission process of the first information.

[0365] In some embodiments, the terms "downlink control information (DCI)", "downlink (DL) assignment", "DL DCI", "uplink (UL) grant", "UL DCI" and the like may be used interchangeably.

[0366] Step S3104: The first communication device sends a first signal to the Ambient IoT device based on the first information.

[0367] In some embodiments, the first communication device may implement transmission control of the first signal based on the first information to ensure that the Ambient IOT device can receive the corresponding first signal.

[0368] In some embodiments, the first communication device may determine a sending method of the first signal based on the first information, and thereby send the first signal to the Ambient IOT device according to the determined sending method.

[0369] In some embodiments, determining the sending method of the first signal based on the first information includes but is not limited to determining the sending time of the first signal (including but not limited to the sending start time, sending stop time, sending duration, etc.), determining the sending period of the first signal, determining whether to continue sending the first signal, etc., and the embodiments of the present disclosure are not limited to this.

[0370] Through the above steps S3103 to S3104, the second communication device can send the first information to the first communication device, so that the first communication device can implement the sending control of the first signal according to the first information. In more possible implementation methods, the second communication device can also determine the sending method of the first signal based on the first signal, and generate indication information indicating the sending method based on the determined sending method, thereby sending the determined indication information to the first communication device, so that the first communication device can directly implement the sending of the first signal according to the received indication information.

[0371] In some embodiments, controlling the sending of the first signal may be controlling

[0372] In some embodiments, "obtain", "get", "get", "receive", "transmit", "bidirectional transmission", "send and / or receive" can be interchangeable, and can be interpreted as receiving from other entities, obtaining from protocols, obtaining from higher layers, obtaining by self-processing, autonomous implementation, etc.

[0373] In some embodiments, terms such as "send", "transmit", "report", "download", "transmit", "bidirectional transmission", "send and / or receive" can be used interchangeably.

[0374] In some embodiments, terms such as "certain", "preset", "preset", "setting", "indicated", "a certain", "any", and "first" can be interchangeable. "Specific A", "preset A", "preset A", "setting A", "indicated A", "a certain A", "any A", and "first A" can be interpreted as A pre-specified in a protocol, etc., or as A obtained through setting, configuration, or indication, etc., or as specific A, a certain A, any A, or first A, etc., but not limited to this.

[0375] In some embodiments, the determination or judgment can be performed by a value represented by 1 bit (0 or 1), or by a true or false value (Boolean value) represented by true or false, or by comparison of numerical values ​​(for example, comparison with a predetermined value), but is not limited thereto.

[0376] In some embodiments, "not expecting to receive" can be interpreted as not receiving on time domain resources and / or frequency domain resources, or as not performing subsequent processing on the data after receiving it; "not expecting to send" can be interpreted as not sending, or as sending but not expecting the recipient to respond to the content sent.

[0377] The communication method involved in the embodiment of the present disclosure may include at least one of steps S3101 to S3104. For example, step S3103 can be implemented as an independent embodiment, step S3104 can be implemented as an independent embodiment, steps S3101+S3103 can be implemented as an independent embodiment, steps S3101+S3104 can be implemented as an independent embodiment, steps S3101+S3102+S3103 can be implemented as an independent embodiment, steps S3101+S3102+S3104 can be implemented as an independent embodiment, and steps S3101+S3103 can be implemented as an independent embodiment. +S3104 can be implemented as an independent embodiment, step S3102+S3103 can be implemented as an independent embodiment, step S3102+S3104 can be implemented as an independent embodiment, step S3101+S3102+S3103 can be implemented as an independent embodiment, step S3101+S3102+S3104 can be implemented as an independent embodiment, step S3101+S3103+S3104 can be implemented as an independent embodiment, but is not limited to this.

[0378] In some embodiments, steps S3102 and S3103 may be performed simultaneously.

[0379] In some embodiments, steps S3101, S3102, and S3103 are optional, and one or more of these steps may be omitted or replaced in different embodiments.

[0380] In some embodiments, steps S3101, S3102, and S3104 are optional, and one or more of these steps may be omitted or replaced in different embodiments.

[0381] In some embodiments, reference may be made to other optional implementations described before or after the description corresponding to FIG. 3 .

[0382] According to the solution provided by the embodiment of the present disclosure, the second communication device sends first information to the first communication device, where the first information is used to control the first communication device to send a first signal related to Ambient IOT.

[0383] In some embodiments, the first signal includes at least one of an energy signal and a CW signal.

[0384] In some embodiments, the second communication device may be a UE, a gNB, a core network function node, or an independent first signal control node.

[0385] In some embodiments, the second communication device may be part of the Ambient IOT topology, or the second communication device may be independent of the Ambient IOT topology.

[0386] In some embodiments, the first communication device may be a UE, a gNB, a core network function node, or an independent first signal sending node.

[0387] In some embodiments, the first communication device may be part of the Ambient IOT topology, or the first communication device may be independent of the Ambient IOT topology.

[0388] Optionally, in the network topology shown in Figure 2A (for ease of explanation, it will be referred to as network topology 1 below), the CW node (i.e., the first communication device) can be gNB1 (gNB that sends commands to Ambient IOT devices), gNB2 (gNB outside the TP1 architecture), CN functional node, UE or other independent CW nodes.

[0389] For example, if the UE acts as a CW node in network topology 1, the first information can be sent to the UE by the gNB / CN functional node in MAC signaling / RRC signaling / DCI signaling / NAS signaling.

[0390] For another example, if gNB1 serves as a CW node in network topology 1, the first information may be determined based on the internal implementation of gNB1, or sent to gNB1 by the CN functional node through NGAP signaling or NG signaling.

[0391] For another example, if gNB2 serves as a CW node in network topology 1, the first information may be sent by gNB1 or a CN functional node to gNB2 in Xn signaling or NG signaling.

[0392] For another example, if the CN functional node serves as a CW node in network topology 1, the first information can be sent by gNB1 to the CN functional node in NG signaling.

[0393] It should be noted that if other independent non-3GPP visible nodes are used as CW nodes in the network topology 1, the first information is beyond the scope of 3GPP, and the first signal transmission control process is not standardized.

[0394] Optionally, in the network topology shown in Figure 2B (for ease of explanation, it will be referred to as network topology 2 below), the CW node can be UE1 (UE as an intermediate node), UE2 (gNB outside the network topology 2 architecture), gNB3 (gNB with RRC connection to UE1), CN functional node or other independent CW node.

[0395] For example, if UE1 serves as a CW node in network topology 2, the first information may be sent to UE1 via MAC signaling / RRC signaling / DCI signaling / NAS signaling, or implemented internally by UE1.

[0396] For another example, if UE2 serves as a CW node in network topology 2, the first information can be sent to UE2 by gNB1 or the gNB to which UE2 is currently connected through inter-UE signaling / RRC signaling / DCI signaling / MAC signaling, or sent to UE2 by the CN functional node through NAS message.

[0397] For another example, if gNB1 serves as a CW node in network topology 2, the first information may be sent by the CN functional node to gNB1 in UE1 UL signaling or NG signaling.

[0398] For another example, if the CN functional node serves as a CW node in the network topology 2, the first information may be sent to the CN functional node via a UL NAS or NG message.

[0399] It should be noted that if other independent non-3GPP visible nodes are used as CW nodes in network topology 2, the first information is beyond the scope of 3GPP, and the first signal transmission control process is not standardized.

[0400] In some embodiments, the first information includes at least one of the following:

[0401] (1) Ambient IoT command information, including at least one of an Ambient IoT command identifier and an Ambient IoT command type.

The above can be an absolute value or a relative value (for example, relative to the Ambient IoT command transmission leading N slots).
