[0055] FIG1A is a schematic diagram showing the architecture of a communication system according to an embodiment of the present disclosure.

[0056] As shown in FIG. 1A , a communication system 1100 may include a first AIOT device 1101 and a second AIOT device 1102 .

[0057] In some embodiments, the first AIOT device 1101 may be any one of a terminal, a network device, an intermediate node, an auxiliary node, and the like.

[0058] In some embodiments, the second AIOT device 1102 may be any one of a network device, an intermediate node, and an auxiliary node.

[0059] In some embodiments, the intermediate node may be a relay, an Integrated Access Backhaul (IAB) node, a User Equipment (UE), a repeater (RP), and the like.

[0060] In some embodiments, as shown in FIG1A , taking the first AIOT device 1101 as a terminal and the second AIOT device 1102 as a base station as an example, downlink (DL) and uplink (UL) data reception and transmission can be performed directly between the first AIOT device 1101 and the base station.

[0061] In some embodiments, as shown in FIG1B , FIG1B is an architectural diagram of another communication system according to an embodiment of the present disclosure. FIG1B uses the second AIOT device 1102 as an intermediate node. The first AIOT device 1101 and the base station can also indirectly perform DL and UL data reception and transmission through the second AIOT device 1102.

[0062] In some embodiments, the terminal includes, for example, a mobile phone, a wearable device, an Internet of Things device, a car with communication function, a smart car, a tablet computer, a computer with wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, and at least one of a wireless terminal device in a smart home, but is not limited thereto.

[0063] In some embodiments, the access network device is, for example, a node or device that accesses a terminal to a wireless network. The access network device may include an evolved NodeB (eNB), a next generation evolved NodeB (ng-eNB), a next generation NodeB (gNB), a node B (NB), a home node B (HNB), a home evolved nodeB (HeNB), a wireless backhaul device, a radio network controller (RNC), a base station controller (BSC), a base transceiver station (BTS), a base band unit (BBU), a mobile switching center, a base station in a 6G communication system, an open base station (Open RAN), a cloud base station (Cloud RAN), a base station in other communication systems, and at least one of an access node in a Wi-Fi system, but is not limited thereto.

[0064] In some embodiments, the technical solution of the present disclosure can be applied to the Open RAN architecture. In this case, the interfaces between or within the access network devices involved in the embodiments of the present disclosure can be transformed into internal interfaces of the Open RAN, and the processes and information interactions between these internal interfaces can be implemented through software or programs.

[0065] In some embodiments, the access network device can be composed of a centralized unit (CU) and a distributed unit (DU), where the CU can also be called a control unit. The CU-DU structure can be used to split the protocol layer of the access network device, with the functions of some protocol layers centrally controlled by the CU, and the functions of the remaining part or all of the protocol layers distributed in the DU, which is centrally controlled by the CU, but is not limited to this.

[0066] In some embodiments, the communication system may further include a core network device (not shown in the figure). The core network device may be a device including one or more network elements, or may be multiple devices or device groups, each including all or part of the one or more network elements. The network element may be virtual or physical. The core network may include, for example, at least one of an evolved packet core (EPC), a 5G core network (5GCN), and a next generation core (NGC).

[0067] 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.

[0068] The following embodiments of the present disclosure can be applied to the communication system shown in Figures 1A and 1B, or part of the subject, but are not limited thereto. The subjects shown in Figures 1A and 1B are examples. The communication system may include all or part of the subjects in Figures 1A and 1B, or may include other subjects other than those in Figures 1A and 1B. The number and form of each subject are arbitrary. Each subject can be physical or virtual. The connection relationship between the subjects is an example. The subjects can be connected or disconnected. The connection can be in any manner, either directly or indirectly, and can be wired or wireless.

[0069] 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), 6th generation mobile communication system (6G), 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).

[0070] Optionally, AIOT devices can be divided into Type A AIOT devices (Device A), Type B AIOT devices (Device B), and Type C AIOT devices (Device C). Type A AIOT devices cannot independently generate / amplify signals. For example, they can use a backscatter operating mode. However, they do not have the ability to amplify DL and / or UL signals. Type B AIOT devices have energy storage capabilities but cannot independently generate signals. For example, they can use a backscatter operating mode and use the stored energy to amplify DL and / or UL signals. The modulation and demodulation methods that can be used by Type A AIOT devices / Type B AIOT devices are relatively simple, such as On-Off Keying (OOK) modulation / Phase Shift Keying (PSK) modulation. Type C AIOT devices have energy storage capabilities and can independently generate signals, such as having a Radio Frequency (RF) module that actively transmits signals. Type C AIOT devices can also use more complex modulation and coding methods, such as Orthogonal Frequency Division Multiplexing (OFDM) modulation and demodulation, and can amplify uplink or downlink signals.

[0071] Optionally, among the three types above, Device C has the strongest capabilities and the highest cost. Device A has the weakest capabilities and the lowest cost. Furthermore, because Devices A and B can only operate in backscatter mode and cannot actively transmit signals, they require external sources of continuous wave (CW) electromagnetic waves for backscattering when they need to transmit information. This results in a smaller coverage range, but the power consumption of Device A / Device B in this mode is much lower than that of Device C.

[0072] Optionally, backscatter-based operation means that when the AIOT device sends data, it needs an energy source that provides a carrier wave (CW) or a continuous electromagnetic wave (CW) (also known as a CW node) to provide it with electromagnetic waves for reflection. Among them, CW generally has a constant amplitude. The CW node can be a separate node or a base station / intermediate node (such as UE) that communicates with the AIOT device. The AIOT device reflects the received CW, loads the signaling / data to be transmitted onto the reflected wave, and sends the reflected wave. The reflected wave and the CW have the same frequency or a certain frequency offset. At the same time, the CW can also charge the AIOT device. For example, the AIOT device can receive the wireless signal CW, activate the internal receiving and processing module, and start working to encode and modulate the signaling / data to be uploaded by the AIOT device.

[0073] AIOT devices have the characteristics of small memory, low processing power, low power consumption, small data transmission volume, large connections, and high coverage. Therefore, the design of downlink channels in AIOT scenarios needs to comprehensively consider these characteristics. Some channel designs can be streamlined to reduce implementation complexity and product complexity.

[0074] Optionally, AIOT devices may operate in unlicensed frequency bands. Therefore, it is necessary to consider how AIOT devices can access channels and send signaling or data in unlicensed frequency bands.

[0075] Optionally, a Listen Before Talk (LBT) operation refers to a device measuring a received signal strength indication (RSSI). When the RSSI measurement value is less than a threshold, the LBT is considered successful and channel occupation can be initiated for a period of time.

[0076] FIG2A is an interactive diagram of a communication control method according to an embodiment of the present disclosure. As shown in FIG2A , the present disclosure embodiment relates to a communication control method that can be used in a communication system 100. The method includes:

[0077] Step S2101: The terminal performs LBT operation.

[0078] In some embodiments, the terminal may perform an LBT operation and initiate a channel occupancy time (COT). The terminal may also share the initiated COT with the AIOT device so that the AIOT device can use the COT shared by the terminal to send signaling or data.

[0079] In some embodiments, AIOT devices may operate in unlicensed frequency bands.

[0080] In some embodiments, the AIOT devices include at least one of the following: a first type of AIOT device, wherein the first type of AIOT device does not have the ability to perform listen-before-talk (LBT) operations; and a second type of AIOT device, wherein the second type of AIOT device has the ability to perform LBT operations. This allows various AIOT devices to effectively access channels, ensuring efficient signaling or data transmission.

[0081] The AIOT device in this embodiment may specifically be, for example, a first-class AIOT device. For AIOT devices that do not have the ability to perform LBT operations, a COT initiated by a terminal and shared with the AIOT device may be used to send signaling or data.

[0082] Step S2102: After LBT is successful, the terminal initiates COT and sends COT sharing information to the AIOT device.

[0083] In some embodiments, the terminal initiates COT after LBT is successful, and sends COT sharing information to the AIOT device to share the COT with the AIOT device.

[0084] In some embodiments, COT sharing information is used to describe the COT initiated and shared by the terminal. This COT sharing information can be used by AIOT devices to determine the COT to use for signaling or data transmission. The COT determined by the AIOT device for signaling or data transmission can be referred to as the first COT. In other words, the COT sharing information is used by the AIOT device to determine the first channel occupancy time (COT) for signaling or data transmission.

[0085] In some embodiments, when a terminal sends COT shared information, the COT shared information is carried over any of the following bearers: high-layer signaling, physical layer signaling, uplink control channel, or uplink data channel. This effectively increases the flexibility of COT shared information transmission and makes it suitable for personalized communication scenarios.

[0086] In some embodiments, the terminal may use high-layer signaling to send the COT sharing information. For example, the high-layer signaling may be Radio Resource Control (RRC) signaling or Media Access Control Control Element (MAC CE) signaling.

[0087] In some embodiments, the terminal may use physical layer signaling to send COT sharing information. For example, the physical layer signaling may be a new control signaling used between the terminal and the AIOT device.

[0088] In some embodiments, the terminal may use an uplink control channel or an uplink data channel to send COT shared information. The UE uses a dedicated uplink control channel or an uplink data channel to send COT shared information to the AIOT device.

[0089] In some embodiments, the COT sharing information includes at least one of the following: the channel access priority level used by the terminal to initiate COT; the total length of the COT initiated by the terminal; the start time of the COT initiated by the terminal; the length of the remaining COT; the start time of the remaining COT; a first processing duration, where the first processing duration represents the time between the terminal sending the COT sharing information and the AIOT device receiving and decoding the COT sharing information; information related to frequency domain resources; the identity of the AIOT device; and the identity of the terminal. This effectively improves the accuracy of COT sharing and enables AIOT devices to accurately and efficiently determine the first COT for sending signaling or data, allowing the signaling or data to be correctly sent.

[0090] In some embodiments, the channel access priority level includes at least one of the following: a channel access priority level pre-configured or pre-defined by a network device; a channel access priority level specified by a protocol; or a channel access priority level determined based on a table of correspondences between Quality of Service (QoS) flows and Channel Access Priority Class (CAPC) of uplink information transmitted by a terminal. This allows for flexible determination of the channel access priority level used by a terminal to initiate a COT.

[0091] In some embodiments, after the terminal initiates a COT and determines the COT sharing information, the initiated COT may be a COT shared by the terminal and the AIOT device. In this case, the terminal may share the initiated COT with the AIOT device. In other embodiments, the COT initiated by the terminal may be a COT shared by the terminal, another terminal (such as a terminal in an NR system), and an AIOT device. After the terminal initiates the COT, it may share the COT with another terminal. After the other terminal completes sharing the COT, it sends the COT sharing information to the AIOT device. There is no limitation on this.

[0092] Step S2103: The AIOT device receives the COT sharing information sent by the terminal.

[0093] In some embodiments, the AIOT device can receive COT sharing information sent by the terminal, for example, it can receive COT sharing information sent by the terminal that initiates and shares the COT, or the AIOT device can receive COT sharing information sent by another terminal mentioned above, and the other terminal shares the COT with the AIOT device. The other terminal can receive the COT sharing information sent by the terminal that initiates and shares the COT, and share the COT according to the COT sharing information, and then send the COT sharing information to the AIOT device. There is no restriction on this.

[0094] In step S2104 , the AIOT device determines the remaining COT based on the COT sharing information, and uses the remaining COT as the first COT.

[0095] In some embodiments, after receiving the COT sharing information sent by the terminal, the AIOT device may determine the remaining COT based on the COT sharing information and use the remaining COT as the first COT, which may be used to send signaling or data.

[0096] Step S2105 : The AIOT device uses the first COT to send signaling or data.

[0097] In some embodiments, the AIOT device may use the first COT to send signaling or data to a signaling / data receiving device, without limitation. The signaling / data receiving device may be, for example, any device capable of receiving signaling / data, such as a network device, a terminal, or the like.

[0098] In some embodiments, after determining the first COT, the AIOT device may use the first COT to send signaling or data, thereby enabling the AIOT device operating in the unlicensed frequency band to effectively access the channel to send signaling or data.

[0099] The communication control method involved in the embodiments of the present disclosure may include at least one of steps S2101 to S2105. For example, step S2101 can be implemented as an independent embodiment, step S2102 can be implemented as an independent embodiment, and so on, but the present invention is not limited thereto. Steps S2101+S2102 can be implemented as independent embodiments, and steps S2101+S2102+S2103 can be implemented as independent embodiments, but the present invention is not limited thereto.

[0100] 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.

[0101] In this embodiment, the terminal can perform an LBT operation and initiate a COT after the LBT is successful, and send COT sharing information to the AIOT device. The AIOT device receives the COT sharing information sent by the terminal. The AIOT device determines the remaining COT based on the COT sharing information, and uses the remaining COT as the first COT, and uses the first COT to send signaling or data, so that the AIOT device operating in the unlicensed frequency band can use the COT initiated and shared by the terminal to effectively access the channel to send signaling or data.

[0102] FIG2B is an interactive diagram of a communication control method according to another embodiment of the present disclosure. As shown in FIG2B , the present disclosure embodiment relates to a communication control method that can be used in a communication system 100. The method includes:

[0103] Step S2201: The network device performs an LBT operation.

[0104] In some embodiments, the network device may perform an LBT operation and initiate a COT. The network device may also share the initiated COT with the AIOT device so that the AIOT device can use the COT shared by the network device to send signaling or data.

[0105] In some embodiments, AIOT devices may operate in unlicensed frequency bands.

[0106] In some embodiments, the AIOT devices include at least one of the following: a first type of AIOT device, wherein the first type of AIOT device does not have the ability to perform listen-before-talk (LBT) operations; and a second type of AIOT device, wherein the second type of AIOT device has the ability to perform LBT operations. This allows various AIOT devices to effectively access channels, ensuring efficient signaling or data transmission.

[0107] The AIOT device in this embodiment may specifically be, for example, a first-class AIOT device. For AIOT devices that do not have the ability to perform LBT operations, a COT initiated by a network device and shared with the AIOT device may be used to send signaling or data.

[0108] Step S2202: The network device initiates COT after LBT is successful, and sends COT sharing information to the AIOT device.

[0109] In some embodiments, the network device initiates COT after LBT is successful, and sends COT sharing information to the AIOT device to share the COT with the AIOT device.

[0110] In some embodiments, COT sharing information is used to describe the COTs initiated and shared by network devices. This COT sharing information can be used by AIOT devices to determine the COT to use for signaling or data transmission. The COT determined by an AIOT device for signaling or data transmission can be referred to as the first COT. In other words, the COT sharing information is used by the AIOT device to determine the first channel occupancy time (COT) for signaling or data transmission.

[0111] In some embodiments, when a network device sends COT shared information, the COT shared information can be carried over any of the following bearers: high-layer signaling; physical layer signaling; downlink control channel; or downlink data channel. This effectively increases the flexibility of COT shared information transmission and makes it suitable for personalized communication scenarios.

[0112] In some embodiments, the network device may use high-layer signaling to send the COT sharing information. For example, the high-layer signaling may be RRC signaling or MAC CE signaling.

[0113] In some embodiments, the network device may use physical layer signaling to send COT sharing information. For example, the physical layer signaling is a new type of downlink control information (DCI) used between the base station and the AIOT device, which is transmitted on the downlink control channel.

[0114] In some embodiments, the network device may use a downlink data channel to transmit the COT shared information. For example, the base station may use a dedicated downlink data channel to send the COT shared information to the AIOT device.

[0115] In some embodiments, the COT sharing information includes at least one of the following: the channel access priority level used by the network device to initiate the COT; the total length of the COT initiated by the network device; the start time of the COT initiated by the network device; the length of the remaining COT; the start time of the remaining COT; a second processing duration, where the second processing duration represents the time between the network device sending the COT sharing information and the AIOT device receiving and decoding the COT sharing information; information related to frequency domain resources; the identity of the AIOT device; and the identity of the terminal. This can effectively improve the accuracy of COT sharing and support AIOT devices to accurately and effectively determine the first COT for sending signaling or data, so that the signaling or data can be correctly sent.

[0116] In some embodiments, the channel access priority level includes at least one of the following: a predefined channel access priority level; a protocol-specified channel access priority level; or a channel access priority level determined based on a table of correspondences between Quality of Service (QoS) flows and channel access priority levels (CAPCs) for downlink information transmitted by a network device. This allows for flexible determination of the channel access priority level used by a terminal to initiate a COT.

[0117] In some embodiments, after the network device initiates a COT and determines the COT sharing information, the initiated COT may be a COT shared by the network device and the AIOT device. In this case, the network device may share the initiated COT with the AIOT device. In other embodiments, the COT initiated by the network device may be a COT shared by the network device, a terminal (such as a terminal in an NR system), and an AIOT device. In this case, after the network device initiates the COT, it may share the COT with the terminal. After the terminal has shared the COT, it may send the COT sharing information to the AIOT device. There is no limitation on this.

[0118] Step S2203: The AIOT device receives the COT sharing information sent by the network device.

[0119] In some embodiments, the AIOT device can receive COT sharing information sent by the network device, for example, it can receive COT sharing information sent by the network device that initiates and shares the COT, or the AIOT device can receive COT sharing information sent by the terminal, and the terminal, the network device and the AIOT device share the COT. The terminal can receive the COT sharing information sent by the network device that initiates and shares the COT, and share the COT according to the COT sharing information, and then send the COT sharing information to the AIOT device. There is no limitation on this.

[0120] In step S2204 , the AIOT device determines the remaining COT based on the COT sharing information, and uses the remaining COT as the first COT.

[0121] In some embodiments, after receiving the COT sharing information sent by the network device, the AIOT device can determine the remaining COT based on the COT sharing information and use the remaining COT as the first COT, which can be used to send signaling or data.

[0122] Step S2205: The AIOT device uses the first COT to send signaling or data.

[0123] In some embodiments, the AIOT device may use the first COT to send signaling or data to a signaling / data receiving device, without limitation. The signaling / data receiving device may be, for example, any device capable of receiving signaling / data, such as a network device, a terminal, or the like.

[0124] In some embodiments, after determining the first COT, the AIOT device may use the first COT to send signaling or data, thereby enabling the AIOT device operating in the unlicensed frequency band to effectively access the channel to send signaling or data.

[0125] The communication control method involved in the embodiments of the present disclosure may include at least one of steps S2201 to S2205. For example, step S2201 can be implemented as an independent embodiment, step S2202 can be implemented as an independent embodiment, and so on, but are not limited thereto. Steps S2201+S2202 can be implemented as independent embodiments, and steps S2201+S2202+S2203 can be implemented as independent embodiments, but are not limited thereto.

[0126] 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.

[0127] In this embodiment, the network device can perform an LBT operation and initiate a COT after the LBT is successful, and send COT sharing information to the AIOT device. The AIOT device receives the COT sharing information sent by the network device. The AIOT device determines the remaining COT based on the COT sharing information, and uses the remaining COT as the first COT, and uses the first COT to send signaling or data, so that the AIOT device operating in the unlicensed frequency band can use the COT initiated and shared by the network device to effectively access the channel to send signaling or data.

[0128] It should be noted that, in the following embodiments, descriptions of terms and method steps that are the same as or corresponding to those in the above embodiments can be referred to the above embodiments and will not be repeated below.

[0132] Step S2302: After the LBT operation is successful, the AIOT device determines the first COT.

[0134] Step S2303: The AIOT device uses the first COT to send signaling or data.

[0135] In some embodiments, the AIOT device may use the first COT to send signaling or data to a signaling / data receiving device, without limitation.

[0190] 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.

[0191] The following is an exemplary introduction to the above method.

[0192] Optional embodiment:

[0193] Case 1: The AIOT device is not capable of performing LBT operations.

[0194] An example is given with the terminal being an intermediate node UE.

[0195] First point: The intermediate node UE performs LBT, initiates a COT, and shares the COT with the AIOT device. The AIOT device does not perform LBT and directly uses the COT to send signaling or data.

[0196] Example 1: The intermediate node UE performs type 1 LBT (type 1 LBT). The intermediate node UE initiates a dedicated COT, which is shared by the AIOT device, and sends the COT sharing information to the AIOT device through physical layer signaling or high-layer signaling. After receiving the COT sharing information, the AIOT device determines the remaining COT length and uses the remaining COT to send signaling or data.

[0197] Example 2: The intermediate node UE performs type 1 LBT, and the intermediate node UE initiates a shared COT. The COT can be shared by AIOT devices or other NR UEs. After other NR UEs share the COT, they send the COT sharing information to the AIOT device through physical layer signaling or high-layer signaling. After receiving the COT sharing information, the AIOT device determines the remaining COT length and uses the remaining COT to send signaling or data.

[0198] The intermediate node UE performs type 1 LBT, in which the channel access priority level is determined by:

[0199] Embodiment 1: It is a channel access priority level pre-configured by a network device or pre-defined, such as channel access priority level=1.

[0200] Example 2: One default channel access priority level specified by the protocol.

[0201] Embodiment 3: The UE determines the channel access priority level according to the QoS flow (i.e., 5G QoS identifier (5G QoS Identifier, 5QI)) of the transmitted uplink information and the corresponding table of 5QI and CAPC.

[0202] The COT shared information is carried in the following ways:

[0203] Use high-layer signaling, which is RRC signaling or MAC CE signaling; or use physical layer signaling, which is a new control signaling used between UE and AIOT device; or use UE to use a dedicated uplink control channel or uplink data channel to send COT shared information to AIOT device.

[0204] The COT shared information includes one or more of the following information:

[0205] Indicates the channel access priority level used when the UE initiates the COT.

[0206] Or the total length of the COT initiated by the intermediate node UE.

[0207] Or the start time of the COT initiated by the intermediate node UE.

[0208] Or the remaining COT length, that is, the total length of the COT initiated by the intermediate node UE minus the COT length used by the UE itself.

[0209] Or the start time of the remaining COT, as indicated by an offset value relative to the COT start time.

[0210] Or processing time, indicating the time it takes for the intermediate node UE to send COT to the AIOT device, receive and decode the COT shared information.

[0211] Or information related to frequency domain resources, such as the number of RB sets or the starting position and number of resource block sets (Resource Block set, RB set).

[0212] Or information related to the identifier (ID), indicating the ID of the AIOT device or the ID of the UE. That is, it indicates that the AIOT device or UE can share the COT initiated by the intermediate node.

[0213] Second point: LBT is executed by the base station, and the base station initiates a COT. The base station shares the COT with the AIOT device. The AIOT device does not execute LBT and directly uses COT to send signaling or data.

[0214] Example 1: Type 1 LBT is executed by the base station. The base station initiates a dedicated COT, which is shared by AIOT devices, and sends the COT sharing information to the AIOT devices through physical layer signaling or high-layer signaling. After receiving the COT sharing information, the AIOT device determines the remaining COT length and uses the remaining COT to send signaling or data.

[0215] Example 2: Type 1 LBT is executed by the base station. The base station initiates a shared COT, which can be shared by AIOT devices or other NRUEs. After other NRUEs share the COT, they send the COT sharing information to the AIOT device through physical layer signaling or high-layer signaling. After receiving the COT sharing information, the AIOT device determines the remaining COT length and uses the remaining COT to send signaling or data.

[0216] In Example 2, after other NRUEs share the COT, they send the COT sharing information to the AIOT device through physical layer signaling or high-layer signaling, which is the same as the first point in which the UE sends the COT sharing information to the AIOT device.

[0217] The base station UE performs type1LBT, which uses the following to determine the channel access priority level:

[0218] Example 1: A default channel access priority level specified by the protocol, such as channel access priority level=1.

[0219] Embodiment 2: The base station determines the channel access priority level according to the QoS flow of the transmitted downlink information and the corresponding table of 5QI and CAPC.

[0220] Embodiment 3: One channel access priority level defined on the base station side.

[0221] The COT shared information is carried in the following ways:

[0222] Use high-layer signaling, which is RRC signaling or MACCE signaling; or use physical layer signaling, which is a new DCI used between the base station and the AIOT device, transmitted on the downlink control channel; or the base station uses a dedicated downlink data channel to send COT shared information to the AIOT device.

[0223] The COT shared information includes one or more of the following information:

[0224] Channel access priority level: indicates the channel access priority level used when the base station initiates the COT.

[0225] Or the total length of COT initiated by the base station.

[0226] Or the start time of the COT initiated by the base station.

[0227] Or the remaining COT length, that is, the total length of the COT initiated by the base station minus the COT length used by the base station itself.

[0228] Or the start time of the remaining COT, as indicated by an offset value relative to the COT start time.

[0229] Or processing time, which indicates the time from when the base station sends COT to the AIOT device to receive and decode the COT shared information.

[0230] Or information related to frequency domain resources, such as the number of RBsets or the starting position and number of RBsets.

[0231] Or ID-related information, indicating the ID of the AIOT device or the ID of the UE, that is, indicating that the AIOT device or UE can share the COT initiated by the base station.

[0232] As shown in Figure 7, Figure 7 is a schematic diagram of the corresponding table of 5QI and CAPC in the embodiment of the present disclosure. As shown in Figure 8, Figure 8 is a schematic diagram of the shared COT in the embodiment of the present disclosure.

[0233] Case 2: AIOT devices are capable of performing LBT operations.

[0234] First point: For AIOT devices with strong capabilities, they can perform LBT operations. In this case, the AIOT device itself performs type 1 LBT. After the LBT is successful, it initiates channel occupation and sends data or signaling.

[0235] Second point: LBT is performed by the base station or intermediate node UE, the intermediate node UE initiates a COT, and shares the COT with the AIOT device. The AIOT device executes type2A / 2B / 2C (type2C does not execute LBT). After LBT is successful, the COT is directly used to send signaling or data.
