[0231] The following embodiments of the present disclosure can be applied to the communication system 100 illustrated in FIG. 1A, or part of the subjects, but are not limited thereto. The subjects illustrated in FIG. 1A are examples, and the communication system can include all or part of the subjects in FIG. 1A, or other subjects other than those in FIG. 1A.

Further, a plurality of systems can be applied in combination (for example, combination of LTE or LTE-A and 5G, and the like).

[0233] Optionally, in order to realize the Internet of Things communication, a new low-power ambient Internet of Things (A-IoT) device is introduced. The newly introduced A-IoT device does not need to be configured with a battery and replace the battery, nor does it need to generate energy itself. It can collect energy from the outside world, such as collecting energy based on signals sent by the surrounding environment or surrounding devices, and can communicate based on the collected energy.

[0234] Optionally, the A-IoT device described above can communicate with the terminal and / or network device based on the energy collected from the outside world. For example, the A-IoT device can use a backscatter working mode to send information to the terminal and / or network device, or the A-IoT device can use an active sending working mode to send information to the terminal and / or network device. Optionally, the "backscatter working mode" described above can be, for example, that the terminal and / or network device first sends a continuous wave (CW) signal to the A-IoT device, and the A-IoT device adjusts the matching between the receiving antenna and the impedance according to the information to be sent, enhances the reflection of the incident CW signal, and modulates the perception data obtained by itself onto the reflected signal to complete the sending of data. Optionally, the "active sending working mode" described above can be understood as, for example, actively generating and actively sending signals without CW signal excitation. The A-IoT device can actively generate and actively send signals based on the energy stored in the A-IoT device, and the energy stored in the A-IoT device can be the energy pre-charged in the A-IoT device by the terminal and / or network device.

[0235] Optionally, the A-IoT device described above has multiple different device types, such as a first type of A-IoT device, a second type of A-IoT device, and a third type of A-IoT device. Different types of A-IoT devices correspond to different capabilities.

[0236] Optionally, the first type of A-IoT device has energy storage capability but does not have independent signal generation and amplification capability, and its uplink transmission depends on backscatter transmission. That is, the first type of A-IoT device needs to use a backscatter working mode to send signals to the terminal and / or network device, and its complexity and cost are the lowest and its power consumption is very small.

[0237] Optionally, the second type of A-IoT device has energy storage capability and has independent signal amplification capability, and its uplink transmission depends on backscatter transmission. That is, the second type of A-IoT device can use a backscatter working mode to send signals to the terminal and / or network device, and can also perform power amplification on the transmitted signals.

[0238] Optionally, the third type A-IoT device has energy storage capability and has independent signal amplification capability, and the uplink transmission can be transmitted based on the internally generated signal; that is, the third type A-IoT device can actively send a signal to the terminal and / or network device based on the internally generated signal.

[0239] Alternatively, optionally, the device type of the A-IoT device can be “backscattering” and “non-backscattering”, wherein “backscattering” can refer to transmitting a signal based on backscattering, and “non-backscattering” can refer to actively transmitting a signal. It should be noted that the above-mentioned device type is only an example, and there can be other forms of naming device types, which are not limited in the present disclosure.

[0240] Optionally, the A-IoT device described above can be applied to various communication architectures in a communication system, wherein FIGS. 1B-1F are schematic diagrams of the architecture of the A-IoT device in communication according to an embodiment of the present disclosure.

[0241] Optionally, as shown in FIG. 1B, the A-IoT device (i.e., Ambient IoT device in FIG. 1B) and the network device (such as a base station (BS)) can directly receive and transmit data.

[0242] Optionally, as shown in FIG. 1C, the A-IoT device and the network device (such as a base station (BS)) can indirectly receive and transmit data through an intermediate node, wherein the intermediate node can be a relay, an integrated access and backhaul (IAB) device, a terminal, or a repeater.

[0243] Optionally, as shown in FIG. 1D, the A-IoT device and the network device (such as a base station (BS)) can directly transmit uplink data, and the A-IoT device and the network device (such as a base station (BS)) can indirectly transmit downlink data through an intermediate node.

[0244] Optionally, as shown in FIG. 1E, the A-IoT device and the network device (such as a base station (BS)) can directly transmit downlink data, and the A-IoT device and the network device (such as a base station (BS)) can indirectly transmit uplink data through an intermediate node.

[0245] Optionally, as shown in FIG. 1F, the A-IoT device and the terminal (or user equipment (UE)) can directly receive and send data, and the terminal can be responsible for collecting data of the A-IoT device and forwarding the collected data to the network device.

[0246] Optionally, in some embodiments, the network device, the terminal, and the intermediate node in FIGS. 1B-1F can be collectively referred to as a Reader.

[0247] Optionally, the data transmitted between the Reader and the A-IoT device can include three types: DO-DTT, DT, and DO-A. Optionally, DO-DTT (Device-originated-device-terminated triggered) can be understood as data triggered based on the Reader, such as inventory. DT (Device-terminated) can be understood as an access command. DO-A (Device-originated-autonomous) can be understood as data actively sent by the A-IoT device, such as active reporting triggered by a sensor (sensor) function.

[0248] Optionally, the DO-A data described above can be data actively sent by the A-IOT device when applied to an autonomous driving scenario (such as a speed detection scenario, a vehicle fault detection scenario, etc.). Optionally, the vehicle parts of the A-IOT device can be loaded with multiple integrated sensors. When the data (such as pressure, resistance, temperature, etc.) detected by the integrated sensors exceeds a threshold value, the A-IOT device can send DO-A data to actively initiate communication for alarm, or when the speed of the vehicle exceeds a certain threshold, the A-IOT device can also send DO-A data to actively initiate alarm. The A-IOT device can also be applied to a smart home scenario, such as fire, gas leakage, indoor water leakage detection, etc. When an accident is detected, the A-IOT device can send DO-A data to actively initiate alarm.

[0249] Therefore, according to the above content, the DO-A data can be some urgent data that usually needs to be processed in priority. However, for the intermediate node in FIGS. 1C and 1E, it can be in a radio resource control (RRC) non-connected state, for example, it can be in an RRC idle state (RRC_IDLE) or an RRC inactive state (RRC_INACTIVE). At this time, how the intermediate node sends the DO-A data to the network device is a technical problem to be solved.

In some embodiments, the first information can include data not actively transmitted by the second device, and the second device transmitting the first information based on the first device triggering can be referred to as non-DO-A transmission or other names, which are not limited in the disclosure. For example, non-DO-A data can refer to data transmitted based on the first device triggering, and the non-DO-A data can include DO-DTT data and / or DT data. Optionally, the DO-DTT data can be understood as data triggered by the Reader, such as D2R transmission in the inventory process.

[0270] Optionally, in some embodiments, the non-DO-A service can be understood as, for example, the first device needs to send first information from the second device to the network device, the first information is sent by the second device based on the first device triggering, for example, DO-DTT data and / or DT data. Optionally, the DO-DTT data can be understood as data triggered based on Reader, for example, D2R transmission in the inventory process. For example, the DO-DTT data can include, but is not limited to, Msg1 (Message 1) or Msg3 (Message 3). Optionally, Msg1 can be a 16-bit random number, and Msg3 can include a second device identifier, for example, an Electronic Product Code (EPC), an electronic product code, or a core network assigned identifier. The DT (Device-terminated) data can be understood as D2R transmission in the access command process. For example, the access command can include, but is not limited to, a read command reply, a write command reply, and the like.

[0271] Optionally, in some embodiments, the DO-A service can be understood as, for example, the first device needs to send first information from the second device to the network device, the first information is sent by the second device actively, for example, DO-A data. For example, the first information can be an active report triggered by a sensor function. For example, the second device can be applied to an automatic driving scenario, such as speed detection, vehicle fault detection, and the like. The second device (i.e., an IoT device) is loaded with multiple integrated sensors for vehicle parts, and when the data (such as pressure, resistance, temperature, and the like) detected by the integrated sensors exceeds a determination threshold, the second device initiates communication actively, or when the speed of the vehicle exceeds a certain threshold, the second device can also initiate an alarm actively. Alternatively, the second device can also be applied to a smart home scenario, such as fire, gas leakage, indoor water leakage, and the like. When an accident is detected, the second device can initiate an alarm actively.

[0272] Optionally, in some embodiments, the DO-A service can be understood as, for example, the first device needs to send first scheduling request information from the second device to the network device, the first scheduling request information is sent by the second device actively, and the first scheduling request information is used to request a resource, the resource is used to send first information, and the first information can include DO-A data.

[0273] Optionally, the steps 2101 and 2102 can be executed simultaneously, or the step 2101 can be located before or after the step 2102.

[0274] In step 2103, the first device accesses the network device.

[0275] Optionally, in some embodiments, the first device can be in a non-connected state, which can include an RRC idle state and / or an RRC inactive state. In some embodiments, when the first device is in the RRC idle state, the first device can initiate an RRC connection establishment procedure to access the network device, or when the first device is in the RRC inactive state, the first device can initiate an RRC connection reestablishment procedure to access the network device. Optionally, an access (Access Stratum, AS) layer of the first device can initiate the RRC connection establishment / reestablishment procedure.

[0276] Optionally, in some embodiments, the first device can initiate random access to access the network device.

[0277] Optionally, in some embodiments, the first device can access the network device using the first RACH configuration. For example, the first device can access the network device using the first RACH configuration associated with the first characteristic; for example, the first device receives the first information or the first scheduling request information sent by the second device, the first device is in a non-RRC connected state, and the first device initiates a random access procedure to access the network device using the first RACH configuration associated with the first characteristic. For example, the first device initiates random access by a preamble associated with the first RACH configuration, and for example, the first device initiates random access by an RO resource associated with the first RACH configuration. The definition of the first information and the first scheduling request information is referred to the above embodiments, which will not be repeated here. Thus, the network device can determine the reason why the first device accesses the network device based on the first RACH configuration used by the first device when accessing the network device, so that the network device can be reasonably configured, such as: priority is given to the access of the first device, so as to ensure that the first information or the first scheduling request information can be forwarded to the network device in time, and the communication efficiency in the IOT scenario is ensured.

[0278] Alternatively, in some embodiments, different IOT services are associated with different RACH configurations respectively, and the first device initiates the random access based on the RACH configuration associated with the type of service of the received first information or the first scheduling request information to access the network device. For example, the IOT services can include emergency services and non-emergency services, and the SIB can be used to configure two RACH configurations, for example, a second RACH configuration and a third RACH configuration. For example, the second RACH configuration is associated with emergency services, and the third RACH configuration is associated with non-emergency services. The first device determines that the type of the received first information is a first type or the first device determines that the received first scheduling request information is used to request a resource for transmitting first information of the first type, and the first device initiates a random access procedure through the second RACH configuration to access the network device. For another example, the first device determines that the type of the received first information is a second type or the first device determines that the received first scheduling request information is used to request a resource for transmitting first information of the second type (for example, non-emergency DO-A data), and the first device initiates a random access procedure through the third RACH configuration to access the network device. The definitions of the first type, the second type, the emergency services and the non-emergency services are as described in the above embodiments, which are not repeated here.

[0279] Alternatively, in some embodiments, different IOT services are associated with different RACH configurations respectively, and the first device initiates the random access based on the RACH configuration associated with the type of service of the received first information or the first scheduling request information to access the network device. For example, the IOT services can include emergency services and non-emergency services, and the SIB can be used to configure two RACH configurations, for example, a second RACH configuration and a third RACH configuration. For example, the second RACH configuration is associated with emergency services, and the third RACH configuration is associated with non-emergency services. The first device determines that the type of the received first information is a first type or the first device determines that the received first scheduling request information is used to request a resource for transmitting first information of the first type, and the first device initiates a random access procedure through the second RACH configuration to access the network device. For another example, the first device determines that the type of the received first information is a second type or the first device determines that the received first scheduling request information is used to request a resource for transmitting first information of the second type (for example, non-emergency DO-A data), and the first device initiates a random access procedure through the third RACH configuration to access the network device. The definitions of the first type, the second type, the emergency services and the non-emergency services are as described in the above embodiments, which are not repeated here.

[0280] Step 2104, the first device sends third information to the network device.

[0281] Optionally, the third information can be, for example, a Msg3 message, which can be, for example, an RRC connection setup request (RRCSetupRequest) message or an RRC connection reestablishment request (RRCResumeRequest) message.

[0282] Optionally, the first value can be included in the third information, and the first value can be used to indicate that the reason why the first device accesses the network device is due to receiving the first information or the first scheduling request information. Optionally, the first value can be, for example, a cause value, which can be newly defined, for example: AmbientIOT DO-A. Optionally, the cause value can be generated by an AS layer or a non-access layer (NAS) layer of the first device.

[0283] Optionally, when the cause value is newly defined, a new access category and / or an access identity corresponding to the access also need to be defined. At the same time, the system broadcast also needs to configure a unified access control (UAC) configuration parameter corresponding to the new access category, which can include, for example, uac-BarringFactor, uac-BarringTime, and uac-BarringForAccessIdentity. That is, the newly defined access category is associated with a set of configurations of the above parameters.

[0284] Step 2105: The first device sends second information to the network device.

[0285] Optionally, the second information can include the first information or the first scheduling request information.

[0286] In some embodiments, the first device can send the second information to the network device by using a first bearer, which can be configured by the network device to the first device when the first device enters a connected state (e.g., an RRC connected state). For example, the network device can send first configuration information to the first device, which can be used to configure the first bearer, e.g., the first configuration information can be carried by RRC signaling. In some embodiments, the first configuration information can be used to configure at least one of the following: a bearer identity of the first bearer, a packet data convergence protocol (PDCP) configuration associated with the first bearer, a radio link control (RLC) configuration associated with the first bearer, a medium access control (MAC) configuration associated with the first bearer. Alternatively, in other embodiments, the first bearer can also be a protocol agreed one.

[0287] In some embodiments, the first bearer can be a new signalling radio bearer (SRB) or a new data radio bearer (DRB), and in other embodiments, the first bearer can be an existing SRB or an existing DRB.

[0288] In some embodiments, the priority of the logical channel associated with the first bearer can be the highest priority, e.g., the priority of the logical channel associated with the first bearer can be 1; and / or the prioritized bit rate (PBR) of the logical channel associated with the first bearer can be infinity.

[0289] Optionally, in some embodiments, the first device can send the second information through a first media access control control element (MAC CE). Optionally, the first MAC CE can be associated with a new logical channel ID (LCID) or a new enhanced logical channel ID (eLCID). Optionally, the logical channel priority of the first MAC CE can be higher than the logical channel priority of the second MAC CE; or the logical channel priority of the first MAC CE can be lower than the logical channel priority of the second MAC CE and higher than the logical channel priority of a third MAC CE; or the logical channel priority of the first MAC CE can be lower than the logical channel priority of the third MAC CE and higher than the logical channel priority of a fourth MAC CE. Optionally, the second MAC CE described above can be used for at least one of the following: sending a cell radio network temporary identifier (C-RNTI), sending data of an uplink-common control channel (UL-CCCH); the third MAC CE described above can be used for at least one of the following: beam failure recovery (BFR), configuration grant confirmation, multiple configuration grant confirmations; and the fourth MAC CE described above can be used for sidelink configuration grant confirmation.

[0290] In summary, when the first device receives the first information or the first scheduling request sent by the second device, if the first device is in a non-connected state, the first device will access the network device, and after the first device accesses the network device, the first device can send the first information or the first scheduling request information to the network device through the second information. The second device can be an environmental IoT device or an IoT device. It can be seen that in the embodiments of the present disclosure, when the first device receives information sent by the environmental IoT device or the IoT device in a non-connected state, the first device will access the network device in time to send the information from the environmental IoT device or the IoT device to the network device, so as to ensure that the information of the environmental IoT device or the IoT device is timely delivered to the network device, and the communication efficiency in the IOT scenario is ensured.

[0378] The optional implementation of steps 5101-5105 can refer to the above embodiment description.

[0379] In some embodiments, the above method can include the method described in the above embodiment of the communication system side, the terminal side, the network device side, etc. Here, it is not described again.

[0380] The communication method related to the embodiments of the present disclosure can include at least one of steps 5101-5105. For example, step 5101 can be implemented as an independent embodiment, and step 5102 can be implemented as an independent embodiment, but is not limited thereto.

[0381] In the present embodiment or example, each step can be independent, arbitrarily combined or exchanged in order, the optional mode or optional example can be arbitrarily combined, and can be arbitrarily combined with any step of other embodiments or other examples.

[0382] The following is an exemplary introduction to the above method.

[0383] The present disclosure proposes a data sending method in an IOT scenario, which solves the problem of how to send DO-A data to a network device if the intermediate node is a terminal and is in an RRC_IDLE / INACTIVE state in the IOT scenarios shown in FIG. 1C and FIG. 1E.

[0384] Embodiment 1: The intermediate node receives the first information, and the intermediate node initiates an RRC connection establishment / connection reestablishment.

[0385] Optionally, the intermediate node is in an RRC non-connected state, specifically, the intermediate node is in an RRC_IDLE / INACTIVE state. Exemplarily, the intermediate node is a terminal device. Exemplarily, the first information is a D2R transmission sent by the IOT device. Exemplarily, the first information is a DO-A transmission sent by the IOT device, which includes but is not limited to device identification and / or data. Exemplarily, the device identification can be a temporary identification or a unique identification, such as an EPC or a core network assigned identification. Exemplarily, the device identification can be a random number, such as a random number randomly generated by the device (16 bits or other lengths). Exemplarily, the first information is scheduling request information sent by the IOT device, which is used to indicate that the IOT device has data to be sent and is used to request resources to send the data to be sent.

[0386] Optionally, the intermediate node receives the first information, and the intermediate node is in an RRC_IDLE / INACTIVE state, and the intermediate node initiates an RRC connection establishment / reestablishment process. Specifically, the intermediate node is in an RRC_IDLE state, and the intermediate node initiates an RRC connection establishment process. The intermediate node is in an RRC_INACTIVE state, and the intermediate node initiates an RRC connection reestablishment process. Exemplarily, the intermediate node initiates random access.

[0387] Embodiment 2: The intermediate node initiates random access through a first RACH configuration.

[0388] Optionally, the first RACH configuration is configured by SIB1, specifically, the first RACH configuration is configured by rach-ConfigCommon in SIB1. The first RACH configuration contains preamble and / or RO resource. For example, the first configuration can be the RACH configuration associated with IOT service or DO-A service. The intermediate node initiates RACH by the preamble and / or RO resource associated with IOT feature, and the network side can determine the node attribute based on the RACH configuration (preamble and / or RO resource) to make reasonable configuration and ensure access priority. For example, IOT is added as one of the features by extending FeatureCombination. The existing FeatureCombinationPreambles is extended or reused to configure one or more preambles associated with IOT feature and other associated RACH related parameters, including but not limited to, startPreambleForThisPartition associated with IOT feature, preamble number per SSB for this partition, numberOfPreamblesPerSSB-ForThisPartition, etc. (see the screenshot). Further, the first RACH configuration can be associated with IOT feature or IOT DO-A feature. When DO-A supports different service types (e.g., emergency, non-emergency, etc., or other forms of differentiation), multiple first RACH configurations can be defined, each associated with a different DO-A service type. The intermediate node confirms the received DO-A service type and initiates RACH according to the first configuration corresponding to the different service type.

[0389] Embodiment 3: A new cause value is defined in Msg3 to indicate that the purpose of RRC connection establishment / reestablishment is IOT service.

[0390] Optional embodiment: The AS layer of the UE initiates the RRC connection establishment / re-establishment procedure. In the MSG3 (i.e. RRCSetupRequest or RRCResumeRequest) message, a cause value is included, which can be newly defined, for example: AmbientIOT DO-A. The cause value can come from the AS layer or from the NAS layer. The newly defined cause value is used to indicate that the purpose of the network device RRC connection establishment / re-establishment is to receive the IOT device DO-A transmission.

[0391] If the new cause value is indicated in the MSG3, a new access category and / or Access identity needs to be defined for the corresponding access. At the same time, the system broadcast also needs to configure the UAC (Unified Access Control) configuration parameters corresponding to the new access category. For example, including uac-BarringFactor, uac-BarringTime, uac-BarringForAccessIdentity. That is, the newly defined access category is associated with a set of configuration of the above parameters.

[0392] Embodiment 4: The intermediate node sends the first data to the network device through the first bearer.

[0393] Optional embodiment: The intermediate node enters the RRC connected state, and the network device configures the IOT service related configuration to the intermediate node through the second configuration, which includes but is not limited to the first bearer configuration, which is used to indicate the bearer associated configuration of the intermediate node to the network device transmission received first information, such as bearer identity, bearer associated PDCP configuration, RLC configuration, MAC configuration, etc. Specifically, the first bearer can be a new SRB / DRB or an existing SRB / DRB. The first data contains the first information received by the intermediate node.

[0394] Optional embodiment: Optionally, the priority of the LCH associated with the first bearer is the highest priority, for example, the priority value is 1. Optionally, the PBR of the LCH associated with the first bearer is infinity.

[0395] Embodiment 5: The intermediate node sends the first data to the network device through the first MAC CE.

[0396] Optionally, the intermediate node sends the first data to the network device via a first MAC CE, and the first data contains the first information received by the intermediate node. For example, the first MAC CE is associated with a new LCID or a new eLCID. For example, the logical channel priority of the first MAC CE can be one of the following priorities.

[0397] Embodiments of the present disclosure also provide a device for implementing any of the above methods. For example, a device is provided, which includes units or modules for implementing the steps performed by the terminal in any of the above methods. For another example, another device is provided, which includes units or modules for implementing the steps performed by the network device (e.g., an access network device, a core network function node, a core network device, etc.) in any of the above methods.
