[0208] It can be understood that the communication system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution proposed in the embodiment of the present disclosure. 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.

[0209] The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG1A , or a portion thereof, but are not limited thereto. The entities shown in FIG1A are illustrative only. The communication system may include all or part of the entities shown in FIG1A , or may include other entities other than those shown in FIG1A . The number and form of the entities may be arbitrary. The connection relationship between the entities is illustrative only.

[0210] 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).

[0211] Alternatively, to enable battery-free IoT communication, a new low-power Ambient Internet of Things (A-IoT) device has been introduced. This newly introduced A-IoT device does not require batteries, nor does it need to generate its own energy. Instead, it can harvest energy from the outside world, such as from the surrounding environment or signals sent by surrounding devices, and can communicate based on the harvested energy.

[0212] Optionally, the above-mentioned A-IoT device can specifically communicate with the terminal and / or network device based on the energy collected from the outside world. For example, in some embodiments, the terminal and / or network device can send a signal to the A-IoT device. After the A-IoT device receives the signal, it can send corresponding response information to the terminal and / or network device or perform corresponding operations. Among them, when the A-IoT device sends response information to the terminal and / or network device, it can use a backscatter working mode to send the response information or it can use an active sending working mode to send the response information. Optionally, the above-mentioned "backscatter working mode" can be, for example: the terminal and / or network device first sends an electromagnetic wave (continuous wave, CW) signal to the A-IoT device, and the A-IoT device adjusts the matching between the receiving antenna and the impedance according to the information to be sent, enhances the reflection of the incident CW signal, and modulates the perception data obtained by itself onto the reflected signal to complete the transmission of the data. Optionally, the above-mentioned "active transmission working mode" can be understood as, for example: actively generating signals and actively sending signals without CW signal excitation, wherein the A-IoT device can actively generate signals and actively send signals based on its stored energy, and the energy stored in the A-IoT device can be the energy that the terminal and / or network device pre-charges the A-IoT device.

[0213] Optionally, the aforementioned A-IoT devices may include multiple different types of devices, such as a first type A-IoT device, a second type A-IoT device, and a third type A-IoT device, wherein different types of A-IoT devices correspond to different capabilities.

[0214] Optionally, the above-mentioned first type A-IoT device has energy storage capability, but does not have independent signal generation and amplification capabilities, and its uplink transmission relies on backscatter transmission; that is, the first type A-IoT device needs to use the backscatter working mode to send signals to the terminal and / or network device (such as the aforementioned response information), which has the lowest complexity and cost and very low power consumption.

[0215] Optionally, the above-mentioned second type A-IoT device has energy storage capability and independent signal amplification capability, and its uplink transmission relies on backscatter transmission; that is, the second type A-IoT device can use the backscatter working mode to send signals to the terminal and / or network device, and at the same time can also amplify the power of the sent signal.

[0216] Optionally, the above-mentioned third type A-IoT device has energy storage capability and independent signal amplification capability, and its uplink transmission can be transmitted based on internally generated signals; that is, the third type A-IoT device can actively send signals to the terminal and / or network device based on the internally generated signals.

[0217] Alternatively, the device types of the aforementioned A-IoT devices can be "backscatter" and "non-backscatter," where "backscatter" can, for example, refer to sending signals based on backscattering, and "non-backscatter" can, for example, refer to actively sending signals. It should be noted that the aforementioned device types are merely examples, and other naming formats for device types may exist, which are not specifically limited in this disclosure.

[0218] Optionally, the above-mentioned A-IoT device can be applied to a variety of different communication architectures in the communication system, wherein Figures 1B-1F are architectural diagrams of the A-IoT device communicating with the network device and / or terminal according to the embodiment of the present disclosure.

[0219] Optionally, as shown in FIG1B , data can be directly received and sent between an A-IoT device (ie, the Ambient IoT device in FIG1B ) and a network device (eg, a base station (BS)).

[0220] Optionally, as shown in FIG1C , data can be received and sent indirectly between the A-IoT device and the network device (such as a base station (BS)) through an intermediate node, where the intermediate node can be, for example, a relay, an integrated access backhaul (IAB) device, a terminal, or a repeater.

[0221] Optionally, as shown in FIG1D , uplink data can be directly transmitted between the A-IoT device and the network device (such as a base station (BS)), and downlink data can be indirectly transmitted between the A-IoT device and the network device (such as a base station (BS)) through an intermediate node, which can be, for example, a relay, an IAB device, a terminal, or a repeater.

[0222] Optionally, as shown in FIG1E , downlink data can be directly transmitted between the A-IoT device and the network device (such as a base station (BS)), and uplink data can be indirectly transmitted between the A-IoT device and the network device (such as a base station (BS)) through an intermediate node.

[0223] Optionally, as shown in FIG1F , data can be directly received and sent between the A-IoT device and the terminal (or user equipment (UE)). The terminal can be responsible for collecting data from the A-IoT device and forwarding the collected data to the network device.

[0224] Optionally, in some embodiments, the network device typically sends instructions related to the A-IoT device to the A-IoT device. The instructions may include, for example, a Select instruction, an Inventory instruction, and an Access instruction. The Select instruction may be used by the network device to select an A-IoT device, the Inventory instruction may be used by the network device to perform an inventory operation on the A-IoT device, and the Access instruction may be used by the network device to perform an access operation on the A-IoT device.

[0225] However, currently, with respect to the communication architecture shown in FIG. 1C , FIG. 1D , or FIG. 1E , there is no method for “how the network device sends the above-mentioned instructions to the A-IoT device through the intermediate node.”

[0226] Based on this, the present disclosure provides a communication method that can be used in the communication architecture shown in Figure 1C, Figure 1D, or Figure 1E above, where the network device sends instructions to the A-IoT device through an intermediate node.

[0227] FIG2A is an interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG2A , the embodiment of the present disclosure relates to a communication method for use in a communication system 100, the method comprising:

[0228] Step 2101: The network device sends a second channel to the first device.

[0229] Optionally, the first device may be an intermediate node between the network device and the second device. Optionally, the second device may be an ambient IoT device. In some embodiments, the second device may be the A-IoT device described previously in the embodiment of FIG. 2A. In some embodiments, the second device may also be referred to as a low-power device, a low-power ambient IoT device, an A-IoT device, an A-IoT UE, an A-IoT terminal, an A-IoT Tag, etc., which is not specifically limited in this disclosure. For an introduction to the A-IoT device, please refer to the description previously in the embodiment of FIG. 2A.

[0230] Optionally, the first device may be the intermediate node shown in FIG. 1C , FIG. 1D , or FIG. 1E .

[0231] Optionally, the above-mentioned second channel can be used to schedule the first channel, and the first channel can be used to carry a first instruction. The first instruction can be an instruction related to the second device. For example, the first instruction can be understood as: an instruction that needs to be sent to the second device, and the first instruction is an instruction related to A-IOT.

[0232] Optionally, in some embodiments, the first channel may be a physical downlink shared channel (PDSCH), and the second channel may be a physical downlink control channel (PDCCH).

[0233] Optionally, the above-mentioned "second channel is used to schedule the first channel" can be understood as: the second channel can be used to indicate to the first device the time and frequency resources occupied by the first channel, so that the first device knows on which time and frequency resources the subsequent first channel is sent, thereby facilitating the first device to successfully receive the first channel subsequently.

[0234] Optionally, the first instruction may include but is not limited to at least one of the following types:

[0235] An instruction for selecting a second device;

[0236] An instruction for taking inventory of the second device; an instruction for performing an access operation on the second device.

[0237] Optionally, the above-mentioned "instruction for selecting the second device" can be, for example, a Select instruction or a paging command; in some embodiments, the selection instruction or paging instruction may include but is not limited to fields such as Target, Action, MemBank, Pointer, Length, Mask, CRC, etc., and the present disclosure does not make specific limitations on this. In addition, for a detailed introduction to "Target, Action, MemBank, Pointer, Length, Mask, CRC", please refer to the prior art, and the present disclosure will not go into details therein.

[0238] Optionally, the aforementioned "instruction for performing an inventory on the second device" may be, for example, an Inventory instruction, or may also be referred to as an Inventory instruction, a Query instruction, or a Polling instruction, wherein the Inventory instruction or the Inventory instruction may include at least one of Query, QueryAdjust, QueryRep, ACK, and NAK. For example, the Query command may include, but is not limited to, fields such as sel, session, target, and Q, which are not specifically limited in this disclosure. For a detailed description of "Query, QueryAdjust, QueryRep, ACK, NAK, sel, session, target, and Q," please refer to the prior art, and this disclosure will not elaborate on this.

[0239] Optionally, the aforementioned "instruction for performing an access operation (e.g., a read or write operation) on the second device" may be, for example, an access instruction or a read or write instruction. Exemplarily, it may include an instruction for performing a read operation on the second device, an instruction for performing a write operation on the second device, an instruction for performing a kill operation on the second device, and the like.

[0240] Optionally, in some embodiments, the second channel may be used for other scheduling purposes in addition to scheduling the first channel carrying the first instruction. Therefore, it is necessary to distinguish different application scenarios of the second channel so that after receiving the second channel, the first device can clearly distinguish whether the second channel is used to schedule the first channel carrying the first instruction, and subsequently perform corresponding operations based on different scenarios.

[0241] The following describes in detail how to distinguish whether the second channel is used to schedule the first channel carrying the first instruction.

[0242] Optionally, in some embodiments, the second channel is typically scrambled by a Radio Network Temporary Identifier (RNTI). Based on this, the different types of first instructions described above can correspond to the same or different RNTIs. When different types of first instructions correspond to the same RNTI, it is considered that the different types of first instructions share the same RNTI. When different types of first instructions correspond to different RNTIs, it is considered that the different types of first instructions each correspond to their own RNTI. For example, a selection instruction corresponds to one RNTI, an inventory instruction corresponds to one RNTI, and a read / write instruction corresponds to one RNTI. The selection instruction, the inventory instruction, and the read / write instruction correspond to different RNTIs. Furthermore, in some embodiments, when the second channel described above is used to schedule the first channel carrying the first instruction, the RNTI used to scramble the second channel may be: the RNTI corresponding to the first instruction carried by the first channel scheduled by the second channel; when the second channel is used for other scheduling, that is, when the second channel is not used to schedule the first channel carrying the first instruction, the RNTI used to scramble the second channel is different from the RNTI corresponding to the first instruction.

[0243] Thus, when different types of first instructions correspond to the same RNTI, after the first device receives the second channel, it can distinguish whether the second channel is used to schedule the first channel carrying the first instruction based on the RNTI scrambled with the second channel, so that corresponding operations can be performed based on different situations. Furthermore, when different types of first instructions correspond to the same RNTI, there is no need to set corresponding RNTIs for different types of first instructions, thereby saving resources and reducing communication complexity.

[0244] In addition, when different types of first instructions correspond to different RNTIs, after the first device receives the second channel, it can distinguish whether the second channel is used to schedule the first channel carrying a certain type of first instruction based on the RNTI that scrambles the second channel, for example, whether it is the first channel carrying the selection instruction, so that corresponding operations can be performed based on different situations. Moreover, when different types of first instructions correspond to different RNTIs, effective classification management of different types of first instructions can be achieved to ensure the orderliness of communication.

[0245] Optionally, in other embodiments, the second channel may also be used to configure a first resource for the first device. Optionally, the first resource may be used, for example, for the first device to send a first instruction to at least one second device. That is, when the first device subsequently sends the first instruction to the at least one second device, it may send the instruction via the first resource. Optionally, the first resource may also be referred to as a resource for the first device to send the first instruction, which is not specifically limited in this disclosure.

[0246] Step 2102: The network device sends a first channel to the first device.

[0247] For a detailed description of the first channel, please refer to the above embodiment.

[0248] Optionally, in some embodiments, when the network device sends the first channel, it may send the first channel on the time-frequency resource indicated by the aforementioned second channel, so that the first device can successfully receive the first channel on the time-frequency resource.

[0249] Optionally, in some embodiments, the first channel may also be used to configure the first resource mentioned above to the first device. For a detailed introduction to the first resource, please refer to the above step description.

[0250] Step 2103: The first device determines a first resource.

[0251] For a detailed introduction to the first resource, please refer to the above step description.

[0252] In some embodiments, the method for the first device to determine the first resource may include at least one of the following:

[0253] determining a preconfigured first resource;

[0254] Determining the first resource based on the agreement;

[0255] receiving a first resource configured by a network device through a first channel;

[0256] receiving a first resource configured by a network device through a second radio resource control (RRC) signaling;

[0257] receiving a first resource configured by a network device through a second medium access control layer control element (MAC CE) signaling;

[0258] A first resource configured by the network device through the second channel is received.

[0259] Optionally, in the embodiment of FIG2A , the second MAC CE signaling may be any MAC CE signaling, and the second RRC signaling may be any RRC signaling.

[0260] Step 2104: The first device sends a first instruction on the first resource.

[0261] Optionally, after receiving the first channel, the first device may first determine the first instruction carried by the first channel, and then send the first instruction on the first resource.

[0262] In the above embodiment, the network device will send a first message carrying a first instruction to the first device, and after receiving the first message, the first device can determine the first instruction and send the first instruction to the second device. The first device is an intermediate node between the network device and the second device, the second device is an environmental Internet of Things device, and the first instruction is an instruction related to the second device. It can be seen that the embodiment of the present disclosure provides a method for how a network device specifically sends instructions related to the environmental Internet of Things device to the environmental Internet of Things device through an intermediate node for the scenario of "the first device acts as an intermediate node between the network device and the environmental Internet of Things device", so that the network device can successfully send instructions related to the environmental Internet of Things device to the environmental Internet of Things device through the intermediate node, thereby ensuring successful communication between the network device and the environmental Internet of Things device.

[0263] The communication method involved in the embodiments of the present disclosure may include at least one of steps 2101 to 2104. For example, step 2101 may be implemented as an independent embodiment, step 2102 may be implemented as an independent embodiment, and steps 2101+2102 may be implemented as independent embodiments, but are not limited thereto.

[0264] In this embodiment or example, unless there is any contradiction, each step can be independent, arbitrarily combined or exchanged in order, the optional methods or optional examples can be arbitrarily combined, and can be arbitrarily combined with any steps of other embodiments or other examples.

[0265] FIG2B is an interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG2B , the embodiment of the present disclosure relates to a communication method for use in a communication system 100, the method comprising:

[0266] Step 2201: The network device sends a first MAC CE signaling to the first device.

[0267] For a detailed introduction to the first device, please refer to the above embodiment description.

[0268] Optionally, the first MAC CE signaling may be used to carry a first instruction. For a detailed introduction to the first instruction, reference may be made to the above embodiment.

[0269] Optionally, in some embodiments, different types of first instructions may be carried by the same first MAC CE signaling, i.e., different types of first instructions may share the same first MAC CE signaling; or, different types of first instructions may be carried by different first MAC CE signaling, i.e., different types of first instructions may each correspond to their own first MAC CE signaling. For example, a select instruction corresponds to one first MAC CE, an inventory instruction corresponds to one first MAC CE, and a read / write instruction corresponds to one first MAC CE, and the select instruction, inventory instruction, and read / write instruction correspond to different first MAC CEs.

[0270] Optionally, in some embodiments, when different types of first instructions are carried by the same first MAC CE signaling, the first MAC CE signaling may include a first indicator bit, which can be used to indicate the type of the first instruction carried by the first MAC CE signaling. Thus, the first indicator bit can be used to determine which type of first instruction the first MAC CE signaling specifically carries.

[0271] Optionally, in some embodiments, the first indicator bit may be an N-bit indicator bit, where N is a positive integer, wherein different values ​​of the N-bit indicator bit indicate different types of the first instruction carried by the first MAC CE signaling. For example, in some embodiments, the first indicator bit may be a 2-bit indicator bit, and when the 2-bit first indicator bit is a first value (e.g., 00), it is used to indicate that the first instruction carried by the first MAC CE signaling is an "instruction for selecting a second device"; when the 2-bit first indicator bit is a second value (e.g., 01), it is used to indicate that the first instruction carried by the first MAC CE signaling is an "instruction for taking inventory of the second device"; and when the 2-bit first indicator bit is a third value (e.g., 10), it is used to indicate that the first instruction carried by the first MAC CE signaling is an "instruction for reading, writing, or accessing the second device." It should be noted that this is merely an example, and there may be other implementations for indicating which type of first instruction the first MAC CE carries, and this disclosure does not specifically limit this.

[0272] Optionally, in some embodiments, when different types of first instructions are carried by different first MAC CE signaling, the first MAC CE corresponding to the inventory instruction may include a second indicator bit, which is used to indicate the type of inventory instruction carried by the first MAC CE signaling. Thus, the second indicator bit can be used to determine which type of inventory instruction is specifically carried by the first MAC CE signaling.

[0273] For example, in some other embodiments, the second indicator bit can be a 2-bit indicator bit. When the 2-bit second indicator bit is a first value (such as 00), it is used to indicate that the first instruction carried by the first MAC CE signaling is a "Query instruction"; when the 2-bit second indicator bit is a second value (such as 01), it is used to indicate that the first instruction carried by the first MAC CE signaling is a "QueryAdjust instruction"; when the 2-bit second indicator bit is a third value (such as 10), it is used to indicate that the first instruction carried by the first MAC CE signaling is a "QueryRep instruction". It should be noted that this is only an example, and there may be other implementation forms to indicate which type of inventory instruction the first MAC CE specifically carries, and this disclosure does not specifically limit it.

[0274] Optionally, in some embodiments, since the network device usually sends multiple MAC CE signalings to the first device, the contents carried by different MAC CE signalings may be different, that is, in addition to sending the first MAC CE signaling for carrying the first instruction to the first device, the network device also sends other MAC CE signalings other than the first MAC CE signaling to the first device, and the contents carried by the other MAC CE signalings are different from the contents carried by the first MAC CE signaling. Therefore, it is usually necessary to distinguish the different MAC CE signalings sent by the network device to the first device, so that after the first device receives the first MAC CE signaling, it can clearly distinguish that the first MAC CE signaling is used to carry the first instruction, so that the corresponding operation can be performed smoothly subsequently.

[0275] The following describes in detail how to distinguish different MAC CE signaling sent by the network device to the first device.

[0276] Optionally, in some embodiments, MAC CE signaling generally corresponds to a logical channel identifier (LCID) or an enhanced logical channel identifier (eLCID). Based on this, by making the LCID corresponding to the first MAC CE signaling different from the LCID corresponding to other MAC CE signalings except the first MAC CE signaling; and / or, by making the eLCID corresponding to the first MAC CE signaling different from the eLCID corresponding to other MAC CE signalings except the first MAC CE signaling, different MAC CE signalings sent by the network device to the first device are distinguished. On this basis, after the first device receives the first MAC CE signaling, it can distinguish that the first MAC CE signaling is used to carry the first instruction based on the LCID or eLCID corresponding to the first MAC CE signaling, and the first device can subsequently perform the step of "sending the first instruction to the second device".

[0277] Thus, when different types of first instructions correspond to the same first MAC CE signaling, after the first device receives the first MAC CE signaling, it can distinguish whether the first MAC CE signaling is a MAC CE signaling for carrying the first instruction based on the LCID or eLCID of the first MAC CE signaling, so that corresponding operations can be performed based on different situations. Furthermore, when different types of first instructions correspond to the same first MAC CE signaling, there is no need to set corresponding first MAC CE signaling for different types of first instructions, thereby saving resources.

[0278] Furthermore, when different types of first instructions correspond to different first MAC CE signaling, after the first device receives the first MAC CE signaling, it can distinguish whether the first MAC CE signaling is used to carry a certain type of first instruction, such as whether it is a first MAC CE signaling carrying a selection instruction, based on the LCID or eLCID of the first MAC CE signaling, so that corresponding operations can be performed based on different situations. Furthermore, when different types of first instructions are carried by different first MAC CE signaling, effective classification and management of different types of first instructions can be achieved, ensuring the orderliness of communication.

[0279] Optionally, in some other embodiments, the first MAC CE signaling may also be used to configure a first resource for the first device. For a detailed introduction to the first resource, reference may be made to the description of the above embodiment.

[0280] Step 2202: The first device determines a first resource.

[0281] For a detailed introduction to the first resource, please refer to the above step description.

[0282] In some embodiments, the method for the first device to determine the first resource may include at least one of the following:

[0283] determining a preconfigured first resource;

[0284] Determining the first resource based on the agreement;

[0285] receiving a first resource configured by a network device through a first MAC CE signaling;

[0286] Receiving a first resource configured by the network device through a second RRC signaling;

[0287] The first resource configured by the receiving network device through the second MAC CE signaling.

[0288] Optionally, in the embodiment of FIG. 2B , the second MAC CE signaling may be a MAC CE signaling different from the first MAC CE signaling, and the second RRC signaling may be any RRC signaling.

[0289] Optionally, in some embodiments, the first resource may also be configured through a channel, for example, the first resource may be configured through PDCCH and / or PDSCH.

[0290] Step 2203: The first device sends a first instruction on the first resource.

[0291] For a detailed description of step 2203, please refer to the above embodiment description.

[0292] In the above embodiment, the network device will send a first message carrying a first instruction to the first device, and after receiving the first message, the first device can determine the first instruction and send the first instruction to the second device. The first device is an intermediate node between the network device and the second device, the second device is an environmental Internet of Things device, and the first instruction is an instruction related to the second device. It can be seen that the embodiment of the present disclosure provides a method for how a network device specifically sends instructions related to the environmental Internet of Things device to the environmental Internet of Things device through an intermediate node for the scenario of "the first device acts as an intermediate node between the network device and the environmental Internet of Things device", so that the network device can successfully send instructions related to the environmental Internet of Things device to the environmental Internet of Things device through the intermediate node, thereby ensuring successful communication between the network device and the environmental Internet of Things device.

[0293] The communication method involved in the embodiments of the present disclosure may include at least one of steps 2201 to 2203. For example, step 2201 may be implemented as an independent embodiment, step 2202 may be implemented as an independent embodiment, and steps 2201+2202 may be implemented as independent embodiments, but are not limited thereto.

[0294] In this embodiment or example, unless there is any contradiction, each step can be independent, arbitrarily combined or exchanged in order, the optional methods or optional examples can be arbitrarily combined, and can be arbitrarily combined with any steps of other embodiments or other examples.

[0295] FIG2C is an interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG2C , the embodiment of the present disclosure relates to a communication method for use in a communication system 100, the method comprising:

[0296] Step 2301: The network device sends a first RRC signaling to the first device.

[0297] For a detailed introduction to the first device, please refer to the above embodiment description.

[0298] Optionally, the first RRC signaling may be used to carry a first instruction. For a detailed introduction to the first instruction, reference may be made to the above embodiment.

[0299] Optionally, in some embodiments, different types of first instructions may be carried by the same first RRC signaling, that is, different types of first instructions may share the same first RRC signaling; or, different types of first instructions may be carried by different first RRC signalings, that is, different types of first instructions may correspond to their own first RRC signalings. In the case where different types of first instructions are carried by the same first RRC signaling, communication resources can be greatly saved. In addition, in the case where different types of first instructions are carried by different first RRC signalings, effective classification management of different types of first instructions can be achieved to ensure the orderliness of communication.

[0300] Optionally, in some embodiments, for RRC signaling, it generally includes multiple domains and / or multiple information elements (IEs), each domain or IE is used to carry different or the same content, and each domain corresponds to a domain name, and each IE corresponds to an IE name. Based on this, in some embodiments, when the first RRC signaling is used to carry the first instruction, a domain name different from other domains can be set for the domain used to carry the first instruction in the first RRC signaling, or an IE name different from other IEs can be set for the IE used to carry the first instruction in the first RRC signaling, and different domain names can be set for different domains carrying different types of first instructions, or different IE names can be set for IEs carrying different types of first instructions. Thus, when the first device receives the first RRC signaling, it can distinguish which specific domains or IEs in the first RRC signaling are used to carry the first instruction through the domain name or IE name of the first RRC signaling, and distinguish which type of first instruction the first RRC signaling specifically carries, thereby facilitating the subsequent execution of the corresponding process by the first device.

[0310] Optionally, in some embodiments, the first resource may also be configured through a channel, for example, the first resource may be configured through PDCCH and / or PDSCH.

[0311] Step 2303: The first device sends a first instruction on the first resource.

[0312] For a detailed description of step 2303, please refer to the above embodiment description.

[0313] In the above embodiment, the network device will send a first message carrying a first instruction to the first device, and after receiving the first message, the first device can determine the first instruction and send the first instruction to the second device. The first device is an intermediate node between the network device and the second device, the second device is an environmental Internet of Things device, and the first instruction is an instruction related to the second device. It can be seen that the embodiment of the present disclosure provides a method for how a network device specifically sends instructions related to the environmental Internet of Things device to the environmental Internet of Things device through an intermediate node for the scenario of "the first device acts as an intermediate node between the network device and the environmental Internet of Things device", so that the network device can successfully send instructions related to the environmental Internet of Things device to the environmental Internet of Things device through the intermediate node, thereby ensuring successful communication between the network device and the environmental Internet of Things device.

[0422] Optional implementations of steps 5101 to 5103 may refer to the description of the above embodiment.

[0423] In some embodiments, the above method may include the method described in the above embodiments of the communication system side, terminal side, network device side, etc., which will not be repeated here.

For example, step 5101 may be implemented as an independent embodiment, and step 5102 may be implemented as an independent embodiment, but the present invention is not limited thereto.

[0426] The following is an exemplary introduction to the above method.

[0427] Optional Example 1: Define a new RNTI for A-IOT related commands.

[0428] Example: Define a shared RNTI to scramble A-IOT-related DL commands, such as paging (or select) commands, inventory (or query) commands, queryadjust, queryrep, etc. Another possible implementation is to define one or more RNTIs, with each A-IOT-related DL command having its own RNTI, such as the RNTI associated with the paging command and the RNTI associated with the inventory command.

[0429] Embodiment: A network device generates a paging command, which is carried by the PDSCH. The specific paging command may include, but is not limited to, fields such as Target, Action, MemBank, Pointer, Length, Mask, and CRC, which are not specifically limited in this disclosure. A network device generates a query command, which is carried by the PDSCH. The query command may include, but is not limited to, fields such as sel, session, target, and Q, which are not specifically limited in this disclosure.

[0430] Embodiment: The resource for sending the paging command / query command may be pre-configured / protocol-specified, or configured by the network device to the intermediate node UE via RRC signaling, or indicated by the PDCCH scrambled by the RNTI, or indicated by the PDSCH.

[0431] Example: The UE generates a paging command / query command according to the received PDCCH / PDSCH, and then sends the command on a designated resource.

[0432] Optional Example 2: Define a new MAC CE for A-IOT related instructions.

[0433] Embodiment: Define a common MAC CE to carry A-IOT-related DL commands, such as paging (or select) instructions, inventory (or query) instructions, queryadjust, queryrep, etc. The MAC CE uses a new LCID or eLCID. An indicator bit is defined in the MAC CE to indicate the DL command carried by the MAC CE, such as a 1-bit indicator bit, 0 indicates a paging command, and 1 indicates a query command. For example, a 2-bit indicator bit indicates a paging command, a query command, a queryadjust command, and a queryrep command, respectively. Another possible implementation method is to define one or more MAC CEs, each DL command has its own associated MAC CE, and each MAC CE has a new LCID or eLCID.

[0434] Example: A network device generates a paging command, which is carried by a MAC CE. The paging command may include, but is not limited to, fields such as Target, Action, MemBank, Pointer, Length, Mask, and CRC, which are not specifically limited in this disclosure. The network device generates a query command, which is carried by a MAC CE. The query command may include, but is not limited to, fields such as sel, session, target, and Q, which are not specifically limited in this disclosure.
