Wireless communication methods and apparatuses

[0001] Cross Reference to Related Applications

[0002] This application is based on the Chinese patent application No. 202411000145.1 filed on July 24, 2024, and claims the priority of the Chinese patent application No. 202411000145.1, the whole content of which is incorporated herein by reference. TECHNICAL FIELD

[0003] The present application belongs to the field of communication technology, and in particular, relates to a wireless communication method and device. BACKGROUND

[0004] In the research of ambient Internet of Things (AIOT), it is recognized by the industry to introduce a user equipment (UE) as an intermediate node between a network node and an AIOT device to realize communication between the network node and the AIOT device.

[0005] In the related art, the communication between the intermediate node and the AIOT device is controlled by the network node to some extent. Specifically, the network node can allocate resources for AIOT communication to the intermediate node, and the intermediate node communicates with the AIOT device based on the allocated resources.

[0006] However, when the intermediate node directly communicates with the AIOT device based on the resources allocated by the network node, it may not match the actual situation between the intermediate node and the AIOT device, thereby reducing the wireless communication performance. For example, when a burst situation occurs between the intermediate node and the AIOT device or between the intermediate node and the network node, the intermediate node does not consider the burst situation and still communicates with the AIOT device based on the allocated resources, which can result in too low wireless communication performance.

The wearable device includes a smart watch, a smart bracelet, a smart earphone, smart glasses, smart jewelry (a smart bracelet, a smart necklace, a smart ring, a smart necklace, a smart anklet, a smart necklace, and the like), a smart wristband, smart clothing, and the like. The vehicle-mounted device can also be referred to as a vehicle-mounted terminal, a vehicle-mounted controller, a vehicle-mounted module, a vehicle-mounted component, a vehicle-mounted chip, or a vehicle-mounted unit. It should be noted that the specific type of the terminal 11 is not limited in the embodiments of the present application.

[0081] The network-side device 12 can include an access network device.

[0082] The access network device can also be referred to as a radio access network (RAN) device, a radio access network function or a radio access network unit. The access network device can include a base station, a wireless local area network (WLAN) access point (AP) or a wireless fidelity (WiFi) node, etc. Among them, the base station can be referred to as a node B (Node B, NB), an evolved node B (Evolved Node B, eNB), a next generation node B (the next generation Node B, gNB), a new radio node B (New Radio Node B, NR Node B), an access point, a relay base station (Relay Base Station, RBS), a serving base station (Serving Base Station, SBS), a base transceiver station (Base Transceiver Station, BTS), a radio base station, a radio transceiver, a basic service set (Basic Service Set, BSS), an extended service set (Extended Service Set, ESS), a home node B (home Node B, HNB), a home evolved node B (home evolved Node B), a transmission reception point (Transmission Reception Point, TRP), a non-terrestrial network (Non-Terrestrial Network, NTN) device (such as a satellite or a high altitude platform station, etc.) or some other suitable term in the field, as long as the same technical effect is achieved. The base station is not limited to a specific technical term, and it should be noted that in the embodiments of the present application, only the base station in the NR system is taken as an example for introduction, and the specific type of the base station is not limited.

[0083] The environmental Internet of Things device 13 can also be referred to as a passive Internet of Things (Passive-IoT) device, an ambient power (Ambient Power, AMP) device, a zero-power device, a low-power IoT device, a responding device, a tag, etc. It should be noted that the specific type of the environmental Internet of Things device 13 is not limited in the embodiments of the present application.

[0084] In order to better understand the embodiments of the present application, the related technologies of the present application are described.

[0085] 1. AIOT device type.

[0086] An environmental IoT device is characterized by its energy storage capacity and its ability to generate radio frequency signals for transmission. The AIOT device has one of the following energy storage capabilities:

[0087] Storage capacity 1: no ability to store energy.

[0088] Storage capacity 2: energy can be stored up to E1 or E2 Joules, where it is possible that E1 = E2

[0089] Storage capacity 3: energy can be stored up to E2 Joules

[0090] Depending on these storage capacities, environmental IoT devices can be classified as:

[0091] Device A: no energy storage, no independent signal generation / amplification, i.e. backscatter transmission.

[0092] Device B: with energy storage, no independent signal generation, i.e. backscatter transmission. The use of stored energy can include amplification of the reflected signal.

[0093] Device C: with energy storage, with independent signal generation, i.e. active radio frequency components for transmission.

[0094] Different energy storage capabilities of devices also affect the transmission quality of the device. In general, devices with higher energy storage also mean higher reception sensitivity or higher transmission power. That is, the reliability of the reception or transmission link can be better guaranteed.

[0095] 2. AIOT data / service types.

[0096] AIOT data / service types can include the following types:

[0097] Device-originated (DO) communication initiated by the device.

[0098] Device-terminated (DT) communication terminated by the device.

[0099] Device-originated - autonomous (DO-A) data transmission initiated autonomously by the AIOT device.

[0100] Device-originated -device-terminated triggered (DO-DTT) by a reader device such as a base station. In this case, DO and DT data indicate that the data flow originates from or is transmitted to an AIOT device (similar to an RFID tag). For DO data, which originates from an AIOT device, it can be further classified as:

[0101] DO-A: such as connecting a large number of various sensors that collect and actively report information about the environment, devices, and living beings when necessary.

[0102] DO-DTT: such as asset identification, status reporting, and tracking, which are all downlink (DL) triggered reporting, and the reader collects data from the tag by triggering the inventory program. Since the data is generated / initiated in the IoT device, this service should be considered as a DO service initiated by the tag triggered by the command sent by the reader.

[0103] 3. AIOT scenarios.

[0104] Based on the topology of the AIOT device, it can be divided into the following two scenarios:

[0105] The scenario in which the AIOT device directly communicates with the base station (BS). Referring to FIG. 2, the base station BS 22 can directly send AIOT data or signals to the AIOT device 21 or receive AIOT data or signals from the AIOT device 21.

[0106] The scenario in which the AIOT device communicates with the base station BS through an intermediate node. Referring to FIG. 3, the base station BS 22 can send AIOT data or signals to the intermediate node 23 through the Uu interface, and the intermediate node 23 further forwards the AIOT data or signals to the AIOT device 21; or the AIOT device 21 can send AIOT data or signals to the intermediate node 23, and the intermediate node 23 forwards the AIOT data or signals to the base station BS 22.

[0107] The wireless communication method provided by the embodiments of the present application will be described in detail in combination with some embodiments and their application scenarios.

[0108] FIG. 4 is a schematic flowchart of a wireless communication method 310 according to an embodiment of the present application.

[0109] As shown in FIG. 4, the wireless communication method 310 can include at least part of the following contents:

[0110] S311, in a case where the first condition is met, the first device stops or continues the communication with the second device, or determines the first resource for the communication with the second device;

[0111] The first condition comprises at least one of the following:

[0112] The first device receives the first information;

[0113] The first device receives the second information;

[0114] A link between the first device and a third device meets a first specific condition;

[0115] A link between the first device and the second device meets a second specific condition;

[0116] The first information indicates a resource for determining the first resource, the second information is used for indicating the first device to stop or continue the communication with the second device, and the third device is a device for controlling the communication between the first device and the second device.

[0117] Exemplarily, stop (Stop) can also be referred to as cease / suspend (Cease / Suspend), and continue (Continue) can also be referred to as resume / maintain (Resume / Maintain).

[0118] Exemplarily, the first resource is a transmission resource for the communication between the first device and the second device. That is, the first resource can be a transmission resource used or can be used for the communication between the first device and the second device. Optionally, the first device can communicate with the second device based on the transmission resource.

[0119] Exemplarily, the first resource comprises an increased or decreased resource relative to the allocated resource, that is, the first device suggests or requests an increased or decreased resource relative to the allocated resource. Optionally, the amount of the increased or decreased resource can be equal to or not equal to the amount of the allocated resource. Optionally, when the first resource is a decreased resource and is equal to the allocated resource, the first device stops the communication with the second device. Optionally, the allocated resource is a resource allocated by a third device to the first device for the communication with the second device. Optionally, the first resource is a resource for adjusting the allocated resource for the communication between the first device and the second device, that is, the first device can adjust the allocated resource for the communication between the first device and the second device based on the first resource, to obtain a transmission resource for the communication between the first device and the second device.

[0120] For example, the first resource is a resource suggested or requested by the first device. For example, when the beam used by the first device to communicate with the second device is adjusted from beam 1 to beam 2, the first resource is beam 2. Optionally, the first device can report the first resource to the third device.

[0121] For example, the first condition can be configured by a protocol, configured by the third device, or configured by another device. Similarly, the first specific condition can be configured by a protocol, configured by the third device, or configured by another device. The second specific condition can be configured by a protocol, configured by the third device, or configured by another device. In addition, the first condition, the first specific condition, or the second specific condition can be referred to as a predefined rule or other terms with similar meanings, which are not limited in the present application.

[0122] For example, the first information is control information sent by the third device.

[0123] For example, the second information is control information sent by the third device.

[0124] For example, the first information indicates the first resource.

[0125] For example, the first information is used to indicate an allocated resource used by the first device to communicate with the second device.

[0126] For example, the first information is used to adjust an allocated resource used by the first device to communicate with the second device.

[0127] For example, the resource indicated by the first information is a resource indicated by the third device to increase or decrease relative to the allocated resource. Optionally, the amount of the increased or decreased resource can be equal to or not equal to the amount of the allocated resource. Optionally, when the amount of the decreased resource indicated by the first information is equal to the allocated resource, the first device stops communicating with the second device.

[0128] For another example, the first information indicates that all remaining resources used by the first device to communicate with the second device are cancelled, and at this time the first device stops communicating with the second device.

[0129] For another example, the first information is an adjusted resource indicated by the third device. For example, the beam used by the first device to communicate with the second device is beam 1, and the first information indicates beam 2. The first device starts to use beam 2 to communicate with the second device according to the indication of the first information.

[0130] Exemplarily, in a case that the first condition comprises that the first device receives the first information, the first device determines the first resource based on the first information. For example, in a case that the first information is used to indicate an allocated resource for the first device to communicate with the second device, the first device determines the resource suggested or requested by the first device. For another example, in a case that the first information is used to adjust the allocated resource, the first device can adjust the allocated resource based on the resource indicated by the first information to increase or decrease relative to the allocated resource, to obtain a transmission resource for the first device to communicate with the second device, and then communicate with the second device based on the transmission resource. For another example, in a case that the first information is used to adjust the allocated resource, the first device can communicate with the second device based on the adjusted resource indicated by the first information.

[0131] Exemplarily, in a case that the first condition comprises that the first device receives the second information, the first device stops or continues the communication with the second device based on the second information. For example, in a case that the second information indicates the first device to stop the communication with the second device, the first device stops the communication with the second device. For another example, in a case that the second information indicates the first device to continue the communication with the second device, the first device continues the communication with the second device.

[0132] Exemplarily, the first specific condition comprises at least one of:

[0133] a link state between the first device and the third device meets a specific condition;

[0134] a link resource between the first device and the third device meets a specific condition;

[0135] a communication situation of a link between the first device and the third device meets a specific condition.

[0136] Exemplarily, the second specific condition comprises at least one of:

[0137] a link state between the first device and the second device meets a specific condition;

[0138] a link resource between the first device and the second device meets a specific condition;

[0139] a communication situation of a link between the first device and the second device meets a specific condition.

[0140] Exemplarily, the first device can also be referred to as an intermediate device, which can be a device for reading (and sometimes writing) AIOT device information, a device for communicating with a tag, such as a terminal, a base station, or a device with reading and writing functions, for example, a reader / writer, or a core network device, such as a location server or a location management function (LMF), which is not limited herein. Optionally, the first device can send a carrier stimulation signal or a control command. For example, the first device can be a terminal 11 as shown in FIG. 1.

[0141] Exemplarily, the second device can be a responding device, which can communicate by backscattering RF signals or some active tags with the ability to generate signals actively. The energy of the responding device can come from the environment, such as environmental radio frequency (RF) energy, thermal energy, wind energy, kinetic energy, etc., which can also be referred to as an AIOT device. The responding device can be regarded as a terminal or a tag, which can be an active, passive or semi-active device. For example, the second device can be an environmental Internet of Things device 13 as shown in FIG. 1.

[0142] Exemplarily, the third device can be a network side device, for example, the third device can be an access network device 12 as shown in FIG. 1.

[0143] In the embodiments of the present application, by introducing the first condition, in the case of meeting the first condition, triggering the first device to stop or continue the communication with the second device or determining the first resource for the communication with the second device, which is equivalent to adaptively adjusting or controlling the communication between the first device and the second device based on the first condition, thereby improving the performance of wireless communication.

[0144] In some embodiments, the first specific condition includes at least one of the following:

[0145] The first device detects a beam failure;

[0146] The first device detects a radio link failure (RLF);

[0147] The first device switches from a radio resource control (RRC) connected state to an RRC inactive state or an idle state;

[0148] The first device loses uplink synchronization;

[0149] The first device initiates a cell handover;

[0150] The first device initiates a first random access procedure.

[0151] Exemplarily, when the first device detects the beam failure, the first device stops communicating with the second device. Alternatively, when the first device detects the beam failure, the first device continues communicating with the second device.

[0152] Exemplarily, when the first device detects the RLF, the first device stops communicating with the second device. Alternatively, when the first device detects the RLF, the first device continues communicating with the second device.

[0153] Exemplarily, when the first device switches from the RRC connected state to the RRC deactivation state or the idle state, the first device stops communicating with the second device. Alternatively, when the first device switches from the RRC connected state to the RRC deactivation state or the idle state, the first device continues communicating with the second device.

[0156] Exemplarily, when the first device initiates the first random access procedure, the first device stops communicating with the second device. Alternatively, when the first device initiates the first random access procedure, the first device continues communicating with the second device.

[0157] In the embodiment, when the link between the first device and the third device satisfies the first specific condition, the first device is triggered to stop or continue communicating with the second device, which means that the communication between the first device and the second device can be adaptively adjusted or controlled based on the link between the first device and the third device, thereby improving the performance of wireless communication.

Alternatively, when the number of responses of the second device that are not detected by the first device is greater than or equal to a preset threshold value, the first device continues to communicate with the second device.

[0167] In this embodiment, when the link between the first device and the second device satisfies a second specific condition, the first device is triggered to stop or continue the communication with the second device, which means that the communication between the first device and the second device can be adaptively adjusted or controlled based on the link between the first device and the second device, thereby improving the performance of wireless communication.

In other words, when uplink synchronization of the first device is lost and a frequency domain resource used by the first device for the communication with the second device before the cell switching is different from a frequency domain resource used by the first device for the communication with the second device after the cell switching, the first device stops the communication with the second device.

[0184] In the embodiment, in the case where the second condition is satisfied, it is illustrated that the first device is not suitable for continuing the communication with the second device, in which case, the first device is triggered to stop the communication with the second device, and thus the wireless communication performance can be improved.

[0185] In some embodiments, the S311 comprises:

[0186] The first device continues the communication with the second device using a second resource;

[0187] The second resource is determined according to at least one of the following:

[0188] A preconfigured resource;

[0189] Configuration information in configuration information last received by the first device;

[0190] Configuration information in system information received by the first device;

[0191] Configuration information in a switching command received by the first device;

[0192] The configuration information is used for configuring a resource for the communication with the second device.

[0193] Exemplarily, in the presence of the second resource, the second first device continues the communication with the second device using the second resource.

[0194] Exemplarily, the second resource can be referred to as a configured or pre-configured resource, which includes a configured or pre-configured resource for the first device to communicate with the second device. In other words, in the presence of the first condition, the first device can continue the communication with the second device based on the configured or pre-configured resource for the first device to communicate with the second device.

[0195] Exemplarily, the pre-configured resource is a pre-configured resource for the first device to communicate with the second device.

[0196] Exemplarily, when the first device detects the beam failure and the pre-configured resource is present, the first device continues the communication with the second device based on the pre-configured resource. That is, the first device can continue the communication with the second device using the pre-configured resource during the beam failure. Optionally, the pre-configured resource is a resource configured before the beam failure. For example, before the beam failure, the first device uses a first set of resources to communicate with the second device, and after the beam failure, the first device uses a second set of resources to communicate with the second device. The pre-configured resource includes the second set of resources. Optionally, the second set of resources can also be referred to as an exceptional resource.

[0197] Exemplarily, when the first device detects the RLF and the pre-configured resource is present, the first device continues the communication with the second device based on the pre-configured resource. That is, the first device can continue the communication with the second device using the pre-configured resource during the RLF. Optionally, the pre-configured resource is a resource configured before the RLF. For example, before the RLF, the first device uses a first set of resources to communicate with the second device, and after the RLF, the first device uses a second set of resources to communicate with the second device. The pre-configured resource includes the second set of resources. Optionally, the second set of resources can also be referred to as an exceptional resource.

[0198] Exemplarily, when the first device switches from the RRC connected state to the RRC deactivation, the first device can continue the communication with the second device based on the configuration information last received by the first device.

[0199] Exemplarily, when the first device switches from the RRC connected state to the RRC idle state, the first device can continue the communication with the second device based on the configuration information in the system information received by the first device.

[0200] Exemplarily, when the first device initiates the cell switching, the first device can continue the communication with the second device based on the configuration information in the preconfigured resource or the switching command received by the first device.

[0201] In the embodiment, in the case where the second resource exists, even if the first condition is met, the communication quality between the first device and the second device can be guaranteed through the second resource, in which case, triggering the first device to continue the communication with the second device can improve the wireless communication performance.

[0202] In some embodiments, the configuration information last received by the first device is the configuration information last received by the first device before entering the RRC deactivation state, the configuration information last received by the first device for the first device, or the configuration information last received by the first device determined according to the system information.

[0203] Exemplarily, the configuration information for the first device can also be referred to as the dedicated information of the first device.

[0204] In some embodiments, the first condition includes that the first device receives the first information, the first information being used to adjust at least one of the time resource, the frequency domain resource, the power resource, and the beam parameter of the first device for the communication with the second device; and the S311 includes:

[0205] The first device determines the first resource based on the first information.

[0206] Exemplarily, the first resource can be a resource obtained by adjusting the configured or preconfigured resource based on the first information. Optionally, the configured or preconfigured resource includes the configured or preconfigured resource for the communication between the first device and the second device. In other words, in the case where the first device receives the first information, the first device can adjust the configured or preconfigured resource for the communication between the first device and the second device based on the first information to obtain the first resource.

[0207] Exemplarily, the first information is used to increase or decrease at least one of the time resource, the frequency domain resource, the power resource, and the beam parameter of the first device for the communication with the second device.

[0208] For example, the resource indicated by the first information is an increased or decreased resource of the resource indicated by the third device relative to the allocated resource. Optionally, the amount of the increased or decreased resource can be equal to or not equal to the amount of the allocated resource. Optionally, when the amount of the decreased resource indicated by the first information is equal to the allocated resource, the first device stops the communication with the second device. Optionally, the increased or decreased resource can include at least one of a time resource, a frequency domain resource, a power resource, and a beam parameter.

[0209] For another example, the first information indicates to cancel all remaining resources for the first device to communicate with the second device, and the first device stops the communication with the second device.

[0210] For another example, the resource indicated by the first information is an adjusted resource indicated by the third device. Optionally, the adjusted resource can include at least one of a time resource, a frequency domain resource, a power resource, and a beam parameter. For example, the beam used by the first device to communicate with the second device is beam 1. The first information indicates beam 2. The first device starts to use beam 2 to communicate with the second device according to the indication of the first information.

[0211] In the embodiment, when the first condition includes that the first device receives the first information, the first device determines the first resource based on the first information, which means that the first device can adjust the transmission resource used by the first device to communicate with the second device according to the first information, thereby improving the performance of wireless communication.

[0212] In some embodiments, the first information includes a plurality of indication information, and the first device determines the first resource based on the first information, including:

[0213] The first device determines the first resource based on a resource indicated by first indication information in the plurality of indication information.

[0214] The first indication information includes at least one of the following:

[0215] The last received indication information in the plurality of indication information.

[0216] The indication information with the highest priority in the plurality of indication information.

[0217] For example, the first device determines the first resource based on the last received indication information in the plurality of indication information, or the first device determines the first resource based on the indication information with the highest priority in the plurality of indication information.

[0218] In this embodiment, the first device determines the first resource based on the resource indicated by the first indication information in the plurality of indication information. When the first indication information comprises the last received indication information in the plurality of indication information, the real-time performance of the first indication information can be guaranteed, and the real-time performance of the first resource can be guaranteed. When the first indication information comprises the indication information with the highest priority in the plurality of indication information, the effectiveness of the first indication information can be guaranteed, and the effectiveness of the first resource can be guaranteed.

[0219] In some embodiments, the plurality of indication information comprises indication information received from layers in a plurality of layers; wherein the indication information received by the first device from different layers in the plurality of layers indicates the same resource, or the indication information with the highest priority in the plurality of indication information comprises indication information received by the first device from a layer with the highest priority in the plurality of layers.

[0220] For example, the plurality of layers comprises at least one of the following: an L1 layer, a MAC layer, and an RRC layer.

[0221] For example, the indication information received by the first device from different layers in the plurality of layers indicates the same resource. That is, when the first device receives the indication information received from a layer in the plurality of layers, the first device does not expect that the resource indicated by the indication information received from the layer in the plurality of layers is different.

[0222] For example, the indication information with the highest priority in the plurality of indication information comprises indication information received by the first device from a layer with the highest priority in the plurality of layers. Optionally, when the plurality of layers comprises an L1 layer, a MAC layer, and an RRC layer, the priority relationship of the plurality of layers is: L1 layer>MAC layer>RRC layer. Optionally, the indication information received from any layer in the plurality of layers comprises a priority identifier, and the priority identifier is used to indicate the priority of the any layer or the priority of information corresponding to the any layer.

[0223] In this embodiment, the indication information received by the first device from different layers in the plurality of layers indicates the same resource, and the reliability of the first indication information can be guaranteed. The indication information with the highest priority in the plurality of indication information comprises indication information received by the first device from a layer with the highest priority in the plurality of layers, and the effectiveness of the first indication information can be guaranteed, and the effectiveness of the first resource can be guaranteed.

[0224] In some embodiments, the method 310 further comprises:

[0225] The first device communicates with the second device based on the first resource after a predefined time delay after receiving the first information.

[0226] Exemplarily, the predefined time delay is greater than zero.

[0227] In this embodiment, the first device communicates with the second device based on the first resource after a predefined time delay after receiving the first information, which means that a certain information is reserved for the first device to process the first information, i.e., the processing time of the first information cannot occupy the time resource of the first resource, thereby improving the utilization of the first resource.

[0228] In some embodiments, the first information corresponds to a first time range, and the first time range is determined according to at least one of the following:

[0229] one or more time periods during which the first device communicates with the second device;

[0230] a time range between an effective time of the first information and an effective time of next information;

[0231] a predefined time range after the effective time of the first information.

[0232] Exemplarily, the next information can be information received after the first information for determining the first resource.

[0233] Exemplarily, the first time range is determined according to one or more time periods during which the first device communicates with the second device. Optionally, the time period can be a period of a communication resource during which the first device communicates with the second device.

[0234] For example, it is assumed that the first device receives the first information at time slot n, and the first information is used to indicate that the first resource is time slot n+3~n+10. If the period of a communication resource during which the first device communicates with the second device is T, then the first time range is n+3+x*T~n+10+x*T. x represents the number of the one or more time periods, and x=0, 1,....

[0235] Exemplarily, the first time range is determined according to a time range between an effective time of the first information and an effective time of next information. Optionally, the effective time of the first information can be a receiving time of the first information, such as a starting receiving time or an ending receiving time of the first information. Similarly, the effective time of the next information can be a receiving time of the next information, such as a starting receiving time or an ending receiving time of the next information.

[0236] For example, assuming the first device receives the first information at time slot n, and the next information at time slot n+20, the first time range is: n+3~n+20.

[0237] For example, the first time range is determined according to a predefined time range after the effective time of the first information. Optionally, the predefined time range can include a number of time units. Optionally, the time unit includes at least one of the following: frame, subframe, time slot, symbol.

[0238] For example, assuming the first device receives the first information at time slot n, and the next information at time slot n+20, if the predefined time range includes 7 time slots, the first time range is: n+3~n+10.

[0239] For example, the first information can be used to adjust the allocated resources for the first device and the second device to communicate in one or more periods, such as reducing or increasing the resources in one or more periods. When the first information is used to adjust the allocated resources for the first device and the second device to communicate in one period, it can be referred to as one-shot adjustment. When the first information is used to adjust the allocated resources for the first device and the second device to communicate in multiple periods, it can be referred to as multi-shot adjustment. For example, the first information can be used to adjust the allocated resources for the first device and the second device to communicate in one or more periods, and the first device determines to adjust the resources in L periods according to the number of periods indicated by the first information.

[0240] For example, the first information can be used to periodically adjust the allocated resources for the first device and the second device to communicate, such as reducing or increasing the resources in all periods in the resource pool of the allocated resources. For example, the first information can be used to periodically adjust the allocated resources for the first device and the second device to communicate until the first device receives the next information.

[0241] In this embodiment, by introducing the first time range corresponding to the first information, the flexibility of the allocated resources for the first device and the second device to communicate can be improved without changing the first information.

[0242] In some embodiments, the first information is transmitted through layer L1 signaling, a Media Access Control (MAC) Control Element (CE), or RRC signaling, or the second information is transmitted through layer L1 signaling, a MAC CE, or RRC signaling.

[0243] Of course, the first information can also be transmitted through other information, which is not limited in the present application. For example, the first information can be transmitted through system information.

[0244] In some embodiments, the method 310 further includes:

[0245] The first device reports third information;

[0246] The third information includes at least one of the following:

[0247] Second indication information for indicating information for the first device to stop communicating with the second device;

[0248] Third indication information for indicating the first device to request, release, or suggest resources for communicating with the second device.

[0249] For example, when the first device requests, releases, or suggests resources for communicating with the second device, the third indication information can be used to indicate the first resource.

[0250] For example, the third indication information is used to indicate the first device to request increased or decreased resources for communicating with the second device. Or the third indication information is used to indicate that the first device has released resources for communicating with the second device. Or the third indication information is used to indicate the first device to suggest increased or decreased resources for communicating with the second device.

[0251] In this embodiment, the first device reports the third information, which can synchronize the communication state of the first device and the second device to the first device, and can improve the control effect of the third device controlling the first device to communicate with the second device.

[0252] In some embodiments, the third information is transmitted through at least one of the following: a physical uplink control channel (PUCCH), a physical random access channel (PRACH), a first physical uplink shared channel (PUSCH); or the third information is transmitted through at least one of the following: a first scheduling request (SR), a first buffer status report (BSR), user equipment assistance information (UAI), a first uplink control information (UCI) type, a media access control (MAC) control element (CE), RRC signaling.

[0253] Of course, in other alternative embodiments, the third information can also be reported through other types of uplink channels or signals, which are not limited in the present application.

[0254] In some embodiments, the priority of at least one of the first SR, the first BSR, and the first UCI type is determined according to a predefined rule or network configuration; or the first SR corresponds to a different SR configuration from other SRs for specific purposes; or the first BSR corresponds to a different logical channel from other BSRs for specific purposes.

[0255] For example, the priority of the first UCI type and other UCI, such as hybrid automatic repeat request-acknowledgement (HARQ-ACK) and channel state information (CSI), is determined according to a predefined rule or network configuration.

[0256] For example, the first SR corresponds to a different SR configuration from other SRs for specific purposes.

[0257] For example, the first SR is an SR for AIOT communication resource request / release / suggestion, i.e., the SR for AIOT communication resource request / release / suggestion corresponds to a different SR configuration from other SRs for specific purposes.

[0258] For example, each of the logical channel, the beam failure recovery from a cell, the beam failure recovery of a beam failure detection reference signal (BFD RS) set, the consistent listen before talk (LBT) failure recovery, the AIOT transmission can be mapped to zero or one SR configuration, which is configured by RRC.

[0259] For example, the first BSR corresponds to a different logical channel from other BSRs for specific purposes.

[0260] For example, the first BSR is a BSR for AIOT communication resource request / release / suggestion, i.e., a BSR for AIOT communication resource request / release / suggestion corresponds to a different logical channel from other BSRs for specific purposes.

[0261] For example, the SR configuration of the logical channel triggering a BSR, a DSR, a beam failure recovery from a cell, a beam failure recovery of a BFD RS set, a consistent LBT failure recovery, an activation / deactivation request of a positioning measurement interval, or an AIOT transmission is considered as an SR configuration corresponding to the triggering SR.

[0262] In the embodiment, the first SR corresponds to a different SR configuration from other SRs for specific purposes, which can reduce interference of the first SR; and the first BSR corresponds to a different logical channel from other BSRs for specific purposes, which can reduce interference of the first BSR.

[0263] In some embodiments, the first PUSCH includes a configuration grant (CG) PUSCH; and the CG PUSCH does not multiplex data of other logical channels, or the third information has the highest priority in the CG PUSCH.

[0264] For example, before the first device reports the third information to the third device, the first device receives CG PUSCH configuration information from the third device, which is used to configure a CG PUSCH for transmitting the third information.

[0265] In some embodiments, the third information satisfies at least one of the following conditions:

[0266] The priority of the logical channel corresponding to the third information is determined according to a predefined rule or network configuration;

[0267] The third information corresponds to a different logical channel from other uplink data of a specific communication system;

[0268] The resource for transmitting the third information is within the allocated resource of the first device for communicating with the second device.

[0269] The resource for transmitting the third information is not within the allocated resource of the first device for communicating with the second device.

[0270] For example, the resource for transmitting the third information is not within a subset of the allocated resource of the first device for communicating with the second device.

[0271] In this embodiment, by constraining the third information, the interference of the third information can be reduced.

[0272] In some embodiments, the first device reports the third information, comprising:

[0273] The first device periodically reports the third information or triggers the reporting of the third information based on an event.

[0274] In some embodiments, the first device stops the communication with the second device, comprising:

[0275] The first device stops the communication with the second device and releases or does not release the resource for communicating with the second device.

[0276] For example, the first device stops the communication with the second device and releases the resource for communicating with the second device. Alternatively, the first device stops the communication with the second device and does not release the resource for communicating with the second device.

[0277] The following will take the first device as an intermediate device, the second device as an AIOT device, and the third device as a network node as an example to describe the scheme of the present application.

[0278] In an AIOT system, introducing a UE as an intermediate node and an AIOT device to communicate is a common scenario. In this scenario, the communication between the UE and the AIOT device needs to be controlled by the network node to a certain extent.

[0279] It should be noted that in the scenario of introducing the UE as an intermediate node and AIOT device communication (such as the scenario shown in FIG. 3), the network node can allocate resources for AIOT communication for the intermediate device. However, due to the network node may not be able to accurately obtain various parameters between the intermediate device and the AIOT device, such as the number of AIOT devices to be inventoried, and the distance of the intermediate device, etc., the network node allocated resources may be over or insufficient. In addition, if the AIOT communication occupies the resources of the NR system, for example, in-band deployment, the resources available for AIOT communication may change with the resources occupied by the NR system. Therefore, in order to improve resource efficiency, a solution is needed to support the network node to adjust the resources allocated by the network node to the intermediate device for AIOT communication, and a solution is needed to support the intermediate device to adjust or assist the network node to adjust the resources allocated by the network node to the intermediate device for AIOT communication. In addition, in some scenarios, the intermediate device needs to forward the content communicated with the AIOT device to the network node, so when the Uu channel between the intermediate device and the network node is problematic, the intermediate device may not be able to feedback the corresponding content. In this case, the intermediate device stops communicating with the AIOT device, which can avoid resource waste. And when the Uu channel between the intermediate device and the network node is problematic, the network node may not be able to well allocate the parameters of AIOT communication to avoid interference, for example, to avoid interference of multiple intermediate devices, or to avoid interference of the intermediate device to the NR UL / DL signal, etc. In addition, when the resources used by the intermediate device for AIOT communication conflict with the resources used by the intermediate device to communicate with the network node, for example, on the same carrier, a method is also needed to solve the conflict.

[0280] In this application, a related solution is provided for the network node to adjust the resources of the intermediate device for AIOT communication, the intermediate device to use the resources according to the indication of the network node, the intermediate device to assist the base station to adjust the resources, and the intermediate device to stop / interrupt / resume communication with the AIOT device.

[0281] The following will be specifically described in conjunction with specific embodiments.

[0282] Embodiment 1:

[0283] In some deployment scenarios, the network node needs to control the resources used for communication with the AIOT device to some extent to improve the performance of the AIOT system. For example, to reduce the interference / interruption of the AIOT system to the NR system and more efficient coexistence of the NR system, to reduce the interference between different intermediate devices (to reduce the interference between different intermediate devices, or the interference between the intermediate device and the network node) and the interference between different AIOT devices, to ensure that the intermediate device can send or receive the required information to / from the AIOT device, to improve the resource utilization of the AIOT system, etc.

[0284] According to an implementation, the intermediate device determines to stop / continue the communication with the AIOT device according to a predefined rule. The continuation of the communication with the AIOT device can use the resources before a certain event occurs or another set of resources. Specifically, at least one of the following is included:

[0285] (1) When the intermediate node detects a beam failure (BF), the intermediate node stops AIOT communication.

[0286] The BF is the BF of the link between the intermediate device and the network node. During the link recovery procedure, the intermediate node does not communicate with the AIOT. After the completion of the link recovery procedure, the intermediate device can communicate with the AIOT again. Optionally, after the completion of the link recovery procedure, the intermediate device can use the resource configuration received before detecting the BF for communication between the intermediate device and the AIOT device.

[0287] Optionally, if the UE reader detects a beam failure, the UE reader stops AIOT transmission.

[0288] Optionally, if the beam failure recovery is successfully completed, the UE reader resumes the AIOT transmission using the last resource configuration before the beam failure detection.

[0289] Optionally, when the UE reader performs the link recovery procedure, the terminal reader does not send or receive data to / from the AIOT device before the completion of the link recovery procedure.

[0290] Optionally, after the completion of the link recovery procedure, if the intermediate device receives a new AIOT communication resource configuration, the AIOT communication is performed based on the new configuration information. The AIOT communication resource configuration can be carried in the information in the random access procedure of the link recovery procedure or in separate information.

[0291] (2) When the intermediate node detects RLF, the intermediate device stops AIOT communication.

[0292] The RLF is an RLF of a link between the intermediate device and a network node, such as an RLF on a primary cell (PCell). During the RRC reestablishment procedure, the intermediate node does not communicate with the AIOT. After the RRC reestablishment is completed, the intermediate device can resume AIOT communication. Optionally, after the RRC reestablishment is completed, the intermediate device can use the resource configuration received before the RLF is detected for AIOT communication with the AIOT device. Optionally, after the RRC reestablishment is completed, the intermediate device can start AIOT communication with the AIOT device after receiving a new AIOT communication resource configuration.

[0293] Optionally, a UE reader / writer can detect an RLF. When the RLF is detected, the UE reader / writer performs an RRC reestablishment procedure. During the RRC reestablishment procedure, the UE reader / writer stops AIOT transmission. After successfully performing the RRC reestablishment procedure, the UE reader / writer waits for a new AIOT transmission configuration to resume AIOT transmission.

[0294] Optionally, for (1) or (2), if the network node configures exceptional resources, the intermediate device can use the exceptional resources to communicate with the AIOT device during the BLF and the RLF. For example, before the BLF, the intermediate device uses a first set of resources to communicate with the AIOT device, and after the BLF occurs, the intermediate device uses a second set of resources (exceptional resources) to communicate with the AIOT device.

[0295] (3) When the intermediate device goes from an RRC connected state to an RRC inactive state, the intermediate device can continue to communicate with the AIOT device based on the last received network-provided configuration information for the intermediate device to communicate with the AIOT.

[0296] Optionally, if the intermediate device is in an RRC inactive state and the intermediate device selects a cell that is different from the cell configured for AIOT communication by the intermediate device, the intermediate device stops AIOT communication.

[0297] Optionally, if the intermediate device is in an RRC inactive state and the intermediate device does not detect a suitable cell, the intermediate device stops AIOT communication.

[0298] Optionally, when the UE reader / writer changes from an RRC_CONNECTED state to an RRC_INACTIVE state, the UE reader / writer can continue AIOT transmission according to the last received AIOT transmission configuration.

[0299] Optionally, if the cell selected by the RRC_INACTIVE UE reader is not the last serving cell that received the AIOT transmission configuration, the UE reader will stop AIOT transmission. If the RRC_INACTIVE UE reader does not detect a suitable cell, the UE reader will stop AIOT transmission.

[0300] (4) When the intermediate device goes from RRC connected state to RRC inactive state, the intermediate device can stop AIOT communication.

[0301] (5) When the intermediate device goes from RRC connected state to RRC idle state, the intermediate device stops AIOT communication.

[0302] (6) When the uplink synchronization of the intermediate node is lost, the intermediate device stops AIOT communication.

[0303] The uplink out-of-sync is the uplink out-of-sync of the link between the intermediate device and the network node, such as the uplink out-of-sync of the PCell, or the uplink out-of-sync of the uplink carrier or TAG corresponding to the carrier on which the network node sends the information controlling the AIOT communication of the intermediate node, or the uplink out-of-sync of the uplink carrier or TAG on which the intermediate device communicates with the AIOT device.

[0304] Optionally, after the intermediate device re-establishes the uplink synchronization, the intermediate device can continue AIOT communication.

[0305] (7-a) When the intermediate node performs cell switching, the intermediate device stops AIOT communication.

[0306] Optionally, the network node releases the resources for AIOT communication of the intermediate device before sending the switching command to the intermediate device.

[0307] Optionally, the intermediate device releases the resources for AIOT communication of the intermediate device after receiving the switching command.

[0308] Optionally, when the intermediate device performs DAPS switching, the intermediate device can continue to communicate with the AIOT device before the random process with the target gNB succeeds and / or before the source cell is released.

[0309] Optionally, after the UE switches to the target cell / gNB, the intermediate device can use the resource configuration for communication between the intermediate device and the AIOT device received before the switching to communicate with the AIOT device.

[0310] Optionally, after the UE switches to the target cell / gNB, the intermediate device can start to communicate with the AIOT device after receiving a new AIOT communication resource configuration.

[0311] Optionally, when the frequency domain resource for the intermediate device to communicate with the AIOT device is the same cell as the frequency domain resource for the handover, the intermediate device stops AIOT communication. If the carrier / cell for the intermediate device to communicate with the AIOT device is different from the carrier / cell for the handover, for example, PCell handover, but the resource for AIOT communication is on a secondary cell (SCell), the intermediate device can continue AIOT communication. Because in this scenario, after the cell handover, the carrier for AIOT communication does not change, the previously configured resource can continue to be used. Optionally, if the carrier / cell for the intermediate device to communicate with the AIOT device is different from the carrier / cell for the intermediate device to communicate with the AIOT device used by the target gNB for the handover, the intermediate device stops AIOT communication. For example, the current serving gNB of the intermediate device is gNB1, the resource for the intermediate device to communicate with the AIOT device is on cell 3 of gNB1, the intermediate device is handed over to target gNB2, there is no carrier / cell for the intermediate device to communicate with the AIOT device under gNB2, or the available carrier / cell is different, for example, cell 2, then the intermediate device stops AIOT communication.

[0312] (7-b) When the intermediate node performs cell handover, if the network node configures exceptional resources, the intermediate device can use the exceptional resources to communicate with the AIOT device.

[0313] (8) When the intermediate node performs a random access procedure, the intermediate device stops AIOT communication.

[0314] Optionally, the random procedure is triggered by a specific event. The specific event is an event related to the link of the intermediate device with the network node, or an event related to AIOT communication of the intermediate device.

[0315] The specific event is an event related to the link of the intermediate device with the network node, including at least one of the following:

[0316] Initial access from RRC_IDLE;

[0317] RRC connection re-establishment procedure;

[0318] DL or UL data arrives when the uplink synchronization state is "unsynchronized" during RRC_CONNECTED or RRC_INACTIVE in progress during SDT procedure;

[0319] UL data arrives when there is no PUCCH resource available for SR during RRC_CONNECTED or RRC_INACTIVE in progress during SDT procedure;

[0320] Handover except for handover configured with no random access channel (RACH);

[0321] Scheduling request;

[0322] Explicit request from RRC at synchronous reconfiguration;

[0323] RRC connection procedure from RRC_INACTIVE;

[0324] Establish one primary or one secondary timing advance group (TAG);

[0325] Other system information request;

[0326] Beam failure recovery (BFR);

[0327] Consistent uplink LBT failure on SpCell;

[0328] Small data transmission (SDT) in RRC_INACTIVE;

[0329] Positioning purpose requiring random access procedure during RRC_CONNECTED, e.g., when time advance is required for UE positioning;

[0330] Early uplink synchronization for long term measurement (LTM) candidate cell;

[0331] RACH-based LTM cell handover.

[0332] The specific event can be an AIOT communication related event of the intermediate device, including at least one of:

[0333] R2D or D2R data / command arrival during RRC_CONNECTED, but the network node does not allocate resources for AIOT communication for the intermediate device or the network node allocated resources are not enough.

[0334] R2D or D2R data / command arrival during RRC_CONNECTED, but the uplink synchronization state of the intermediate device with the network node is "non-synchronized";

[0335] The number of D2R responses detected by the intermediate node exceeds a predefined threshold N.

[0336] Optionally, the number of undetected D2R responses is a number of consecutive undetected D2R responses. Or, a number of accumulated undetected D2R responses.

[0337] Optionally, the number of undetected D2R responses is a statistical result before a given time window or a timer expires.

[0338] (9) When the cell where the intermediate device communicates with the AIOT device performs BWP (Bandwidth Part) switching, the intermediate device stops AIOT communication.

[0339] Or, when the network node controls the cell where the intermediate device communicates with the AIOT device to perform BWP switching of control information, the intermediate device stops AIOT communication.

[0340] In order to avoid AIOT communication interruption caused by BWP switching as much as possible, according to an implementation mode, the network node does not trigger BWP switching within the time resource allocated for the intermediate device to communicate with the AIOT device. That is, the intermediate device does not expect to receive DCI or MAC or RRC signaling triggering BWP switching so that the intermediate device performs BWP switching within the time resource allocated for the intermediate device to communicate with the AIOT device. According to another implementation mode, the intermediate device suspends the BWP inactivity timer within the time resource allocated for the intermediate device to communicate with the AIOT device, or when communicating with the AIOT device. The BWP inactivity timer is a timer used to monitor the activity state of the UE in a certain BWP. If the UE has no activity in the BWP for a period of time, the timer may trigger BWP switching, that is, the UE switches to another BWP for communication. However, in some cases, such as during communication with the AIOT device, it may be desirable to avoid such switching to reduce interruption and improve efficiency.

[0341] (10) When the intermediate device performs inter-frequency measurement, the intermediate device stops AIOT communication.

[0342] (11) When the network node allocates insufficient resources for AIOT communication for the intermediate device to perform AIOT communication, the intermediate device stops AIOT communication.

[0343] Optionally, insufficient for AIOT communication is insufficient for a round of inventory, or insufficient for sending a command, or insufficient for R2D and the corresponding D2R response of the R2D.

[0344] (12) When the number of undetected D2R responses exceeds a predefined threshold N, the intermediate device stops AIOT communication.

[0345] Optionally, the number of undetected D2R responses is the number of consecutive undetected D2R responses. Alternatively, it is the cumulative number of undetected D2R responses.

[0346] Optionally, the number of undetected D2R responses is the statistical result within a given time window or before timer expiration.

[0347] Embodiment 2:

[0348] According to an implementation, the network node can allocate resources for the intermediate device to communicate with the AIOT device. The resources include at least one of time resources, frequency domain resources, power parameters, beam parameters. The resources for the intermediate device to communicate with the AIOT device include resources for at least one of R2D, D2R, CW transmission between the intermediate device and the AIOT device. The resources can be semi-statically configured or dynamically configured. For example, the network node can allocate a resource pool for the intermediate node to communicate with the AIOT device. The resources of the resource pool are non-periodic or periodically occur. In addition, the network node can also adjust the allocated resources, such as increasing resources, reducing resources, releasing all remaining resources, reallocating resources, etc. The resource adjustment can be semi-statically configured or dynamically configured.

[0349] The intermediate device can attempt to receive the AIOT communication resource control information sent by the network node during the communication with the AIOT device, or before a specific step of the communication with the AIOT device. For example, the intermediate device only receives the control information from the network node before the start of a round of inventory. The intermediate device does not expect the network node to change the resource parameters for the communication between the intermediate device and the AIOT device during the 1 round of inventory. The advantage of this approach is that it can reduce the signaling overhead between the network node and the intermediate device, and the intermediate device does not need to communicate with the network node and the AIOT device at the same time (although the two communications can be on the same or different frequency domain resources, such as on different carriers). For another example, the intermediate device attempts to receive the control information from the network node before the start of the inventory and during the inventory, such as continuously monitoring a specific PDCCH that is used to carry the control information from the network node to control the AIOT communication parameters of the intermediate device. If the intermediate device receives the control information from the network node during the inventory, the intermediate device updates the AIOT communication parameters according to the control information. The advantage of this approach is that the network node can adjust in a more timely manner according to the NR resource usage or the AIOT communication resource usage, and improve resource utilization. This approach can cause the resources for the communication between the intermediate device and the network node and the resources for the communication between the intermediate device and the AIOT device to conflict in time, but this can be solved by a predefined priority rule, or by reasonably allocating the two resources to avoid the conflict, or the two communications are on different frequency domain resources to achieve simultaneous communication.

[0350] Optionally, the intermediate device does not expect the network node to send AIOT communication resource control information again before the end of the time resource indicated by the AIOT communication resource control information sent by the network node. Then the intermediate device can not attempt to receive new control information, or the intermediate device is not required to receive new control information, or the intermediate device is not required to adjust the AIOT communication resource according to the AIOT communication resource control information before the end of the time resource. This simplifies the processing of the intermediate device and saves overhead. Alternatively, the intermediate device can also need to attempt to receive the AIOT communication resource control information sent by the network node before the end of the time resource indicated by the AIOT communication resource control information sent by the network node. This approach can improve resource efficiency.

[0351] The AIOT communication resource control information sent by the network node can be one-shot, multi-shot or periodic adjustment / determination of AIOT communication resources. For example, the resource pool allocated by the network node for the intermediate node to communicate with the AIOT device is periodically present. Subsequently, the AIOT communication resource control information sent by the network node can adjust the resources within one period of this resource pool, for example, cancel all resources within this period or all resources after a reference time point within this period, or reduce / increase the resources within this period. This way can be understood as one-shot update resources. For another example, the AIOT communication resource control information sent by the network node can adjust the resources within N periods of this resource pool. N is configured by the network node or predefined. This way can be understood as multi-shot update resources. For another example, the AIOT communication resource control information sent by the network node can adjust the resources within all periods of this resource pool until the network node sends new control information again. This way can be understood as periodic update resources. Alternatively, the resource pool allocated by the network node can be non-periodic, for example, time slots 0~5 of SFN 3~20 are allocated for the intermediate node to communicate with the AIOT device. The network node sends a resource control information at time slot 0 of SFN 10, releases all resources (time slots 0~5 of SFN 11~20) starting from SFN 11, and no longer uses them for the intermediate node to communicate with the AIOT device. This way can also be understood as one-shot update resources.

[0352] Optionally, the AIOT communication resource control information sent by the network node and the resources for the intermediate device to communicate with the AIOT device are in different frequency domain resources, for example, the AIOT communication resource control information sent by the network node is on a 2.6GHz carrier, and the resources for the intermediate device to communicate with the AIOT device are on a 900MHz carrier. Alternatively, the resources of the two communications can be in the same carrier, and then a predefined rule is needed to avoid mutual influence, for example, through a predefined priority criterion or through a configured time division multiplexing resource to ensure that the intermediate device only performs one kind of communication at a time, or the two communication signals occupy different frequency resources in a carrier, and enough guard band is ensured to reduce interference.

[0353] In this embodiment, the network node can adjust the resources for the intermediate node to communicate with the AIOT device based on the feedback / request / auxiliary information of the intermediate device. Or based on other considerations, for example, AIOT related information obtained from the core network, or transmission in the NR system, to adjust the resources for the intermediate node to communicate with the AIOT device.

[0354] Embodiment 3:

[0355] In some deployment scenarios, the intermediate device has more knowledge about the AIOT devices communicating with the intermediate device than the network node, e.g., the number of AIOT devices, the link condition between the intermediate device and the AIOT devices, etc.

[0356] The intermediate device can make some adjustment within the resources allocated by the network node for the intermediate node to communicate with the AIOT devices. For example, the intermediate device can only use a subset of the allocated resources.

[0357] The intermediate device can send information to the network node to assist the network node to allocate resources for the intermediate node to communicate with the AIOT devices more reasonably. For example, the intermediate device can send the preferred resources to the network node based on the User Assisted Information (UAI), or send a resource request, or send a resource release request, or feedback AIOT link related parameters, e.g., the inventory success rate of the AIOT.

[0358] In addition, if the intermediate device stops AIOT communication due to some events, the intermediate device can actively report to the network node. Optionally, the intermediate device can also request the network to release resources. After the network node responds / acknowledges the request, the intermediate device can release the resources. Alternatively, the intermediate device actively releases the resources, and the intermediate device reports to the network that the resources have been released.

[0359] Another example, if the intermediate device stops AIOT communication and releases AIOT resources, e.g., releases the configuration information of the AIOT resources, in some cases, the intermediate device expects to perform AIOT communication again, and the intermediate device can request AIOT communication resources from the network.

[0360] Optionally, the AIOT sending resource request / release resource request can also include the requested resource parameters, e.g., the requested time resource length, e.g., the value of Q, etc. Similar to BSR.

[0361] Optionally, the preferred resources sent by the intermediate device to the network node, or the requested increased or released resources can be one-shot, multi-shot or periodic resources.

[0362] The intermediate device sends the network node the relevant information of the resources for the intermediate node to communicate with the AIOT device, through PUCCH, RACH process, UCI / MAC-CE / RRC. The first information is carried through SR, BSR, UAI, or a new UCI type, or a new MAC CE, or a new RRC message. For example, the resource request for the intermediate node to communicate with the AIOT device can be carried through the SR of PUCCH. Or a new UCI type (different from the UCI types of SR, CSI, and HARQ-ACK in NR) is introduced. Or the resource adjustment parameter for the intermediate node to communicate with the AIOT device, such as the request for the number of resources to be increased or decreased, can be carried through the BSR of PUSCH / PUCCH.

[0363] Optionally, the relevant information of the resources for the intermediate node to communicate with the AIOT device sent by the intermediate device to the network node corresponds to different logical channels from data / control information for other purposes.

[0364] Optionally, if the relevant information of the resources for the intermediate node to communicate with the AIOT device sent by the intermediate device to the network node is carried through SR, the SR can correspond to different SR configurations from other SRs for specific purposes (such as BFR and LBT FR for NR data).

[0365] Optionally, if the relevant information of the resources for the intermediate node to communicate with the AIOT device sent by the intermediate device to the network node is carried through CG PUSCH, the CG PUSCH can correspond to different CG PUSCH configurations from CG PUSCHs for other purposes, such as CG PUSCHs for NR UL data. The CG PUSCH cannot multiplex data of other logical channels. Alternatively, the CG PUSCH can also be used for NR UL data transmission under certain conditions. The relevant information of the resources for the intermediate node to communicate with the AIOT device sent by the intermediate device to the network node has the highest priority, i.e., the information is transmitted first in the CG PUSCH. When there is no information to be transmitted, or after the information to be transmitted is mapped, there is still spare resources in the CG PUSCH, other logical channels can be multiplexed.

[0366] Optionally, the intermediate device sends the network node the related information of the resource of the intermediate node communicating with the AIOT device, and the resource of the intermediate device communicating with the AIOT device is in different frequency domain resources, for example, the intermediate device sends the network node the related information of the resource of the intermediate node communicating with the AIOT device on a 2.6GHz carrier, and the resource of the intermediate device communicating with the AIOT device is on a 900MHz carrier. Alternatively, the resources of the two communications can be in the same resource, for example, the resource of the CG PUSCH of the related information of the resource of the intermediate node communicating with the AIOT device sent by the intermediate device to the network node is a subset of the resource of the intermediate device communicating with the AIOT device. Then, when the AIOT communication resource required by the intermediate device is less than the allocated resource, the intermediate device can send the CG PUSCH in the remaining AIOT communication resource to inform the network node that the remaining AIOT communication resource is released by the intermediate device, without occupying additional NR resources.

[0367] As shown in FIG. 5, the CG PUSCH resource is configured in the resource allocated by the network node for the intermediate device to communicate with the AIOT device. In the resource used by the intermediate device to communicate with the AIOT device, the intermediate device does not send signals on the CG PUSCH. The intermediate device ends the AIOT device communication and releases the remaining resource, and the intermediate device sends information of releasing the remaining AIOT resource to the gNB on the CG PUSCH.

[0368] It should be noted that the UE is taken as an example in the present application, and the method is also applicable to other intermediate nodes that can communicate with the network node and the AIOT device, such as Integrated Access and Backhaul (IAB) or Non-Cell RAN (NCR). The interaction method of the intermediate device and the network node in the present application is applicable to the Integrated Access and Backhaul Mobility Transfer (IAB-MT) or Non-Cell RAN Mobility Transfer (NCR-MT) part.
