For example, it may be a fixed, portable, pocket-sized, handheld, computer-built-in, or vehicle-mounted device. For example, a station (STA), a subscriber unit, a subscriber station, a mobile station, a mobile station, a remote station, an access point, a remote terminal, an access terminal, a user terminal, a user agent, a user device, or a user equipment (UE). Alternatively, UE 11 may be a device of an unmanned aerial vehicle. Alternatively, UE 11 may be a vehicle-mounted device, such as a driving computer with wireless communication capabilities, or a wireless communication device connected to an external driving computer. Alternatively, the UE 11 may also be a roadside device, for example, a street lamp, a traffic light, or other roadside device with a wireless communication function.

[0238] The network device 12 may include an access network device. Optionally, the network device 12 may also include a core network device. Among them, the access network device may be an evolved access device (eNB) adopted in a 4G system. Alternatively, it may be an access device (gNB) adopting a centralized distributed architecture in a 5G system. When the access network device adopts a centralized distributed architecture, it generally includes a centralized unit (CU) and at least two distributed units (DU). The centralized unit is provided with a protocol stack of a packet data convergence protocol (PDCP) layer, a radio link layer control protocol (RLC) layer, and a media access control (MAC) layer; the distributed unit is provided with a physical (PHY) layer protocol stack. The embodiment of the present disclosure does not limit the specific implementation method of the access network device.

[0239] A wireless connection can be established between the network device 12 and the UE 11 via a wireless air interface. In different implementations, the wireless air interface is a wireless air interface based on the fourth generation mobile communication network technology (4G) standard; or, the wireless air interface is a wireless air interface based on the fifth generation mobile communication network technology (5G) standard, for example, the wireless air interface is a new air interface; or, the wireless air interface can also be a wireless air interface based on the next generation mobile communication network technology standard of 5G.

[0240] Ambient-powered IoT is a technology that can address these unmet needs. An ambient-powered IoT device can be an IoT device powered by energy harvesting, either without a battery or with limited energy storage capabilities (e.g., using capacitors), by harvesting radio waves, light, motion, heat, or any other suitable power source.

[0241] Energy obtained from the environment can drive data transmission and wireless communication of sensing nodes. The current mainstream low-power IoT communication chips (such as BLE, LoRa, and NB-IoT) have a transmit and receive power consumption of tens or even hundreds of milliwatts, while the energy obtained by environmental energy harvesting is only at the microwatt level, which is unable to drive these types of nodes. Therefore, a new wireless communication technology is needed to reduce communication energy consumption to tens of microwatts or even below ten microwatts.

[0242] The methods that can be used include backscatter communications technology.

[0243] As shown in Figure 2, backscatter communication utilizes the principle of RF signal backscattering to design extremely low-power modulation and transmission technologies. A reader sends an excitation signal to an ambient IoT device. Since the excitation signal is partially reflected when it reaches the ambient IoT device, the ambient IoT device can adjust the matching between the receiving antenna and the impedance according to the intended information to enhance reflection of the incident excitation signal. It then modulates the acquired sensor data onto the reflected signal to complete data transmission. This process is similar to a reflector. Compared to other communication technologies, backscatter communication does not require complex RF structures, reducing the use of components such as power amplifiers, high-precision crystal oscillators, duplexers, and high-precision filters. It also does not require complex baseband processing, thus simplifying terminal design and significantly reducing terminal node costs.

[0244] Here, the reader may be a network node of a wireless communication network, such as a base station.

[0245] The network topology for backscatter communication can include one of the following:

[0246] Topology 1: As shown in Figure 3a, uplink (UL) and downlink (DL) data transmission is carried out directly between the ambient IoT device and the base station.

[0247] Topology 2: As shown in Figure 3b, ambient IoT devices and base stations indirectly transmit DL and UL data. Intermediate network nodes (or auxiliary network nodes) are present in the middle to forward data. Examples of these intermediate network nodes include relays, integrated access backhaul (IAB), user equipment (UE), and repeaters (RP).

[0248] Topology 3: As shown in Figure 3c, ambient IoT devices and the base station directly transmit or receive data in the DL or UL. Auxiliary network nodes are present on the UL or DL, responsible for receiving or sending UL or DL ​​data. Examples of auxiliary network nodes include relays, IABs, UEs, and repeaters.

[0249] Topology 4: As shown in Figure 3d, ambient IoT devices and UEs directly receive and transmit data on the downlink and uplink. The UE collects data and forwards it to the network.

[0250] As shown in Figure 4, Ambient IoT devices can be divided into three types:

[0251] Device A: has no energy storage, cannot generate or amplify signals independently, and can only perform backscatter transmission.

[0252] Device B: Has energy storage, cannot generate signals independently, and can only perform backscatter transmission. The use of stored energy can include amplification of the backscattered signal.

[0253] Device C: has energy storage and can independently generate signals, that is, it has active radio frequency (RF) components for transmission.

[0254] Currently, data collection from ambient IoT devices using base stations as anchors requires the deployment of base stations. However, in passive IoT, base station deployment is expensive and unsuitable for rapid deployment.

[0255] To rapidly and cost-effectively deploy passive IoT, a passive IoT data collection method based on UEs as anchor points has been proposed. However, selecting the appropriate UE as the backscatter reader for ambient IoT devices remains a challenge.

[0256] As shown in FIG5 , an embodiment of the present disclosure provides an information processing method, which is executed by an access network device and includes:

[0257] Step 501: receiving motion state information and / or auxiliary information sent by a UE, where the auxiliary information is associated with a location of the UE;

[0258] Step 502: Receive the motion status information sent by the core network device;

[0259] Step 503: Based on at least one of the motion state information and the auxiliary information, determine whether to use the UE as a reader corresponding to the backscattering of the IoT service.

[0260] In one possible implementation, the access network device may include a base station.

[0261] In one possible implementation, a reader in a backscatter transmission of an IoT service is configured to receive at least a backscatter signal sent by an ambient IoT device. In this embodiment, the ambient IoT device may be referred to as an IoT device.

[0262] In one possible implementation, the reader may also be used to send an excitation signal to the IoT device.

[0263] In a possible implementation, the excitation signal may be sent by at least one of the following: a reader, an access network device, or an auxiliary network node (intermediate network node).

[0264] In one possible implementation, the IoT device includes at least one of the following: a tag device, a sensor device, etc.

[0265] In one possible implementation, the IoT device is configured to send a backscattered signal based on an excitation signal.

[0266] In a possible implementation, the frequency band of the excitation signal belongs to the frequency band of cellular mobile communications.

[0267] In one possible implementation, the excitation signal may provide energy for backscattering to the IoT device.

[0268] In one possible implementation, the motion state information may be used to at least determine the motion state of the UE. The motion state of the UE may include: stationary, moving, etc.

[0269] In a possible implementation, the auxiliary information associated with the location of the UE may be used to indicate the location of the UE, or to determine the location of the UE.

[0270] In one possible implementation, the access network device receives motion state information and / or auxiliary information sent by the UE, where the auxiliary information is associated with the location of the UE, and determines whether to use the UE as a backscatter reader corresponding to the IoT service based on at least one of the motion state information and the auxiliary information.

[0271] In one possible implementation, the access network device receives the auxiliary information sent by the UE and receives the motion state information sent by the core network device, and then determines whether to use the UE as a reader corresponding to the backscatter of the IoT service based on at least one of the motion state information and the auxiliary information.

[0272] In a possible implementation, the access network device receives the motion state information sent by the core network device, and determines whether to use the UE as a reader corresponding to the backscatter of the IoT service based on the motion state information.

[0273] Here, the motion state information and / or auxiliary information may be determined by the access network device, or may be sent to the access network device by other devices such as UE and / or core network device.

[0274] Due to the limitations of the signal characteristics (such as signal strength) of the backscattered signals emitted by IoT devices, in order for the reader to receive the backscattered signals and analyze the information carried by the backscattered signals, there are certain requirements on the distance between the reader and the IoT device, the position of the reader, and / or the motion state of the reader.

[0275] For example, the distance between the reader and the IoT device needs to be less than a predetermined distance.

[0276] For example, when the UE acts as a reader, the UE should reside on a cell that has overlapping coverage with the target area (such as the area where the IoT device is located).

[0277] The access network device can determine whether the UE can receive the backscatter signal sent by the IoT device based on the motion state information and / or auxiliary information. The access network device can determine whether the excitation signal sent by the UE can be used to trigger the IoT device to send the backscatter signal and / or determine whether the energy provided by the excitation signal sent by the UE can be used to trigger the IoT device to send the backscatter signal based on the motion state information and / or auxiliary information.

[0278] In this way, the access network device can determine whether the UE can act as a reader based on the motion state information and / or auxiliary information. This ensures that the determined reader can meet the communication requirements with the IoT device and reduces the high cost of deploying the access network device as a reader.

[0279] In some embodiments, the UE is at least one of the following:

[0280] UE with the capability to act as a reader;

[0281] UE authorized as a reader;

[0282] A UE that expects or agrees to act as a reader.

[0283] Here, the access network device determines that a UE capable of acting as a reader must have reader capabilities and / or be authorized as a reader by the network (e.g., core network equipment), and / or the UE desires or agrees to act as a reader. The access network device may first select a UE that meets the above conditions and, among the UEs that meet the above conditions, determine whether the UE can act as a reader based on the UE's motion state information and / or auxiliary information.

[0284] In a possible implementation, the UE may send the dynamic status information and / or the auxiliary information to the access network device in the RRC connected state.

[0285] In a possible implementation, the UE may send its own motion state to the core network device during or after the access process. The core network device may send the UE's motion state information to the access network device.

[0286] In some embodiments, the receiving the motion status information sent by the core network device includes:

[0287] Receive the contract information of the UE associated with the IoT service sent by the core network device, wherein the contract information includes the motion status information.

[0288] In one possible implementation, after accessing the network, a UE can sign up as a reader. The UE can report its motion status to a core network device. The core network device can send the UE's subscription information to the access network device, and the subscription information can include motion status information.

[0289] In some embodiments, the auxiliary information is used to indicate the location of the UE;

[0290] The determining, based on the auxiliary information, whether to use the UE as a reader corresponding to backscattering of an Internet of Things (IoT) service includes:

[0291] Determine whether to determine the UE as the reader according to the location of the UE and the IoT service area corresponding to the IoT service.

[0292] In a possible implementation, the predetermined motion state may include, but is not limited to: a stationary state, and a moving speed less than a predetermined moving speed threshold.

[0293] For example, for fast and low-cost network deployment, the UE may be specially designed or used as a reader. The UE may be in a predetermined motion state and subscribed as a reader.

[0294] In this way, by determining the UE's motion state, it is determined whether the UE can meet the communication needs of the IoT device, thereby improving the accuracy of reader selection; at the same time, it reduces the high cost of deploying access network equipment as a reader.

[0295] In some embodiments, the subscription information of the UE associated with the IoT service includes the motion status information.

[0296] For example, during the registration process of the UE to the network, the UE may sign up as a reader for IoT services and indicate that the UE is stationary.

[0297] Access network equipment can obtain UE's subscription information from core network equipment, and then determine the UE's motion status and determine whether to use the UE as a reader for IoT services.

[0298] In some embodiments, the contract information is used to indicate at least one of the following:

[0299] The UE is a reader corresponding to the backscatter of the IoT service;

[0300] The identifier of the IoT service;

[0301] The location information of the UE.

[0302] The subscription information may indicate that the UE is a reader of the backscatter corresponding to the IoT service, and indicate the identifier of the IoT service. The access network device determines the UE as a reader of the IoT service corresponding to the identifier of the IoT service.

[0303] The access network equipment can also determine the location of the UE based on the contract information.

[0304] In a possible implementation, the location information of the UE may be geographical location information, such as latitude and longitude information, geographical area information, etc.

[0305] In a possible implementation, the location information of the UE may be network location information, indicating the cell to which the UE belongs, etc.

[0306] Exemplarily, when the UE enters the RRC connected state, the core network device pushes the above-mentioned subscription information to the access network device. The subscription information may include the UE ID. The gNB may configure the UE as a reader based on the core network indication information.

[0307] In some embodiments, the auxiliary information is used to indicate the location of the UE;

[0308] The determining, based on the auxiliary information, whether to use the UE as a reader corresponding to backscattering of an Internet of Things (IoT) service includes:

[0309] Determine whether to determine the UE as the reader according to the location of the UE and the IoT service area corresponding to the IoT service.

[0310] The IoT service area corresponding to the IoT service includes but is not limited to at least one of the following:

[0311] The region where the IoT device is located;

[0312] Areas where the distance to the IoT device is less than and / or equal to the distance threshold.

[0313] When the UE is in the IoT service area, the IoT device can send a backscattered signal based on the excitation signal sent by the UE, and the UE can receive the backscattered signal and correctly interpret the information carried by the backscattered signal.

[0314] In one possible implementation, when the UE is in an IoT service area, when the excitation signal sent by the UE reaches the IoT device, the signal quality of the excitation signal is greater than or equal to a predetermined excitation signal quality.

[0315] In one possible implementation, when the UE is in an IoT service area, when a backscatter signal sent by an IoT device reaches the UE, the signal quality of the backscatter signal is greater than or equal to a predetermined backscatter signal quality.

[0316] Exemplarily, when the UE enters the RRC connected state, the base station learns that the UE is capable of supporting becoming a reader and that the UE has been authorized to become a reader (or that the UE is willing to become a reader). The base station configures the UE to report location information (i.e., auxiliary information). The location information can be a precise location, or a location determined based on signal measurement (e.g., RSRP measurement of a co-frequency neighboring cell). After the UE reports its location, the base station determines whether the UE can become a reader based on the location information reported by the UE and the location information about the IOT service area pushed by the core network device. If so, the UE is configured to become a reader.

[0317] In this way, by determining the UE's location, it is determined whether the UE can meet the communication needs of the IoT device, thereby improving the accuracy of reader selection; at the same time, the high cost of deploying access network equipment as a reader is reduced.

[0318] In some embodiments, the auxiliary information includes: area identification information sent by the auxiliary network node and received by the UE, the area identification information is used to identify an IoT service area, and the auxiliary network node is associated with the IoT service area.

[0319] Here, as shown in FIG6 , the auxiliary network node may be between the access network device and the IoT device, responsible for receiving uplink data or sending downlink DL data.

[0320] In one possible implementation, the auxiliary network node is associated with an IoT service area of ​​an IoT service, including but not limited to one of the following:

[0321] The auxiliary network node is within the IoT service area;

[0322] The predetermined wireless signals sent by the auxiliary network nodes can cover the IoT service area.

[0323] In one possible implementation, based on the area identification information, the IoT service area where the UE is located can be determined, and the access network device can then determine whether to configure the UE as a reader.

[0324] In some embodiments, the region identification information is used to indicate at least one of the following:

[0325] The frequency of the wireless signal in the IoT service area;

[0326] The IoT service area is associated with an identifier of the IoT service;

[0327] The identifier of the auxiliary network node.

[0328] The area identification information can be used by the UE or access network equipment to determine the IoT service area where the UE is located.

[0329] The UE may determine whether the predetermined wireless signal is a signal that needs to be measured based on the signal indication information, and determine the IoT service corresponding to the predetermined wireless signal, etc.

[0330] In some embodiments, determining whether to use the UE as a reader corresponding to backscattering of the IoT service based on the auxiliary information associated with the location of the UE includes:

[0331] Determine whether to determine the UE as the reader according to the IoT service area indicated by the area identification information.

[0332] Here, the access network device may determine whether to determine the UE as a reader of the IoT service area associated with the area identification information based on the capability of the UE.

[0333] In a possible embodiment, the access network device may determine, in combination with the subscription information of the UE, whether to determine the UE as a reader of the IoT service area associated with the area identification information.

[0334] For example, when the UE's subscription information indicates that the IoT service the UE has subscribed to is the same as the IoT service in the IoT service area indicated by the area identification information, the access network device can determine the UE as a reader of the IoT service area associated with the area identification information.

[0335] In this way, by determining the IoT service area indicated by the auxiliary information received by the UE, the IoT service area in which the UE is located is determined, and then whether the UE can meet the communication needs of the IoT device is determined, thereby improving the accuracy of reader selection; at the same time, reducing the high cost of deploying access network equipment as a reader.

[0336] As shown in FIG7 , an embodiment of the present disclosure provides an information processing method, which is executed by an access network device and includes:

[0337] Step 701: Receive a first measurement result, where the first measurement result is obtained by the UE performing a first radio signal measurement on a predetermined radio signal, where the predetermined radio signal carries the area identification information;

[0338] Step 702: Based on the first measurement result, determine whether to send a measurement indication to the UE, where the measurement indication is used to instruct the UE to receive the area identification information.

[0339] The area identification information may be broadcast by the secondary group network node.

[0340] In a possible implementation, the access network device may configure the UE to measure the predetermined wireless signal.

[0341] In a possible implementation, the first radio signal measurement may be, but is not limited to, RRM measurement.

[0342] In one possible implementation, when the first measurement result is greater than a first measurement result threshold, the access network device sends a measurement indication to the UE. The first measurement result being greater than the first measurement result threshold may determine that the UE is close to the secondary group network and can communicate with the IoT device.

[0343] In one possible implementation, the measurement indication may indicate at least one of the following: a frequency of a predetermined wireless signal; an identifier of the IoT service; or an identifier of the auxiliary network node. The UE may determine a signal to be measured based on the measurement indication.

[0344] In some embodiments, the auxiliary information includes: a second measurement result determined by the UE performing a second wireless signal measurement on each of the N beams, wherein the beam is associated with the IoT service area of ​​the IoT service; wherein N is a positive integer greater than or equal to 1.

[0345] As shown in FIG8 , the beam is associated with the IoT service area of ​​the IoT service, including but not limited to the following:

[0346] Beams specifically configured for IoT service areas

[0347] The beam points to the IoT service area;

[0348] The beam and IoT service area have overlapping areas;

[0349] The relative position of the UE and the IoT service area can be determined by measuring the beam.

[0350] In some embodiments, the second measurement result is one of the following:

[0351] A measurement value obtained by the UE performing the second radio signal measurement on each beam;

[0352] The sum of the measured value and a predetermined offset value.

[0353] In a possible implementation, the second measurement result may be a measurement value obtained by the UE performing a second radio signal measurement.

[0354] In a possible implementation, the second measurement result may be the sum of a measurement value obtained by the UE performing a second radio signal measurement and a predetermined offset value.

[0355] In one possible implementation, the predetermined offset value may include hysteresis.

[0356] In some embodiments, the measured value includes at least one of the following:

[0357] Reference signal received power RSRP;

[0358] Reference signal received quality RSRQ;

[0359] Signal to Interference and Noise Ratio SINR.

[0360] As shown in FIG8 , the UE can determine the relative position between the UE and the IoT service area by measuring N beams.

[0361] The access network device can configure N dedicated beams for the IoT service area. The access network device can indicate to the UE that N dedicated beams are configured for the IoT service area.

[0362] In one possible implementation, the access network device may send a measurement configuration for measuring the second wireless signal. The measurement configuration may indicate at least one of the following:

[0363] Beam identification information, such as the beam identifier and the cell associated with the beam;

[0364] Second wireless signal measurement items: such as RSRP, etc.;

[0365] Second measurement result reporting method: event-based measurement reporting, or periodic measurement reporting, etc.

[0366] The second measurement result may be used for, but not limited to, at least one of the following:

[0367] Determine the location of the UE;

[0368] Determine the relative position of the UE to the IoT service area.

[0369] The access network device may determine the location of the UE based on the second measurement result, and determine whether the UE can serve as a reader for the IoT service corresponding to the IoT service area.

[0370] In this way, through the two measurement results, the access network device determines the IoT service area where the UE is located, and then determines whether the UE can meet the communication needs of the IoT device, improving the accuracy of reader selection; at the same time, reducing the high cost of deploying the access network device as a reader.

[0371] In some embodiments,

[0372] The determining, based on the auxiliary information, to use the UE as a reader corresponding to backscattering of the IoT service includes at least one of the following:

[0373] If a statistical value of the second measurement results corresponding to M beams out of the N beams is greater than a statistical value threshold, the UE is determined as the reader, where M is a positive integer less than or equal to N;

[0374] The second measurement result corresponding to each beam in the M beams is greater than the first threshold corresponding to each beam, and the UE is determined as the reader;

[0375] The second measurement results corresponding to the M beams are all greater than a second threshold, and the UE is determined to be the reader;

[0376] In some embodiments,

[0377] The determining, based on the auxiliary information, not to use the UE as a reader corresponding to backscattering of the IoT service includes at least one of the following:

[0378] If the statistical values ​​of the second measurement results corresponding to M beams out of the N beams are less than or equal to a statistical value threshold, the UE is not determined as the reader, where M is a positive integer less than or equal to N;

[0379] The second measurement result corresponding to each beam in the M beams is less than or equal to the first threshold corresponding to each beam, and the UE is not determined as the reader;

[0380] At least one of the second measurement results corresponding to the M beams is less than or equal to a second threshold, and the UE is not determined as the reader.

[0381] In one possible implementation, the statistical value threshold may be determined based on a relative position to an IoT service area of ​​the IoT service. If the statistical value of the second measurement results corresponding to each of the M beams is greater than the statistical value threshold, it can be determined that the UE is within the IoT service area, and therefore, it can be determined that the UE can function as a reader.

[0382] In one possible implementation, the statistical value may include but is not limited to one of the following: a linear average; a weighted average.

[0383] In one possible implementation, a first threshold may be set for each beam. The first threshold may be determined based on the UE's relative position to the IoT service area. If the UE obtains a second measurement result for each beam and each second measurement result is greater than the first threshold corresponding to each beam, the UE may be determined to be within the IoT service area and, therefore, may be determined to be capable of functioning as a reader.

[0384] In one possible implementation, the M beams may use the same second threshold. The second threshold may be determined based on the UE's relative position to an IoT service area. If the second measurement results obtained by the UE in each of the M beams are all greater than the second threshold, the UE may be determined to be within the IoT service area, and therefore, the UE may be qualified as a reader.

[0385] The UE can measure all N beams or only M beams. The beams measured by the UE can be configured by the access network device or the core network device.

[0386] In some embodiments, the M beams are one of the following:

[0387] M beams configured by the access network device or core network device;

[0388] Among the N beams, M beams with higher second measurement results;

[0389] Among the N beams, M beams have second measurement results greater than a third threshold.

[0390] The access network device may determine that the UE is a reader. Due to the mobility of the UE, the access network device may also deconfigure the UE as a reader, that is, determine that the UE cannot be used as a reader.

[0391] In one possible implementation, if the statistical value of the second measurement results corresponding to the M beams is less than or equal to the statistical value threshold, it can be determined that the UE cannot meet the requirements of communicating with the IoT device in the IoT service area. Therefore, it can be determined that the UE cannot serve as a reader.

[0392] In one possible implementation, the UE obtains a second measurement result in each beam measurement, which is less than or equal to the first threshold corresponding to each beam. It can be determined that the UE cannot meet the requirements of communicating with the IoT device in the IoT service area. Therefore, it can be determined that the UE cannot be used as a reader.

[0393] In one possible implementation, the second measurement results measured by the UE in M ​​beams are all less than or equal to the second threshold. It can be determined that the UE cannot meet the requirements of communicating with the IoT device in the IoT service area. Therefore, it can be determined that the UE cannot be used as a reader.

[0394] As shown in FIG9 , an embodiment of the present disclosure provides an information processing method, which is executed by an access network device and includes:

[0395] Step 901: Receive indication information sent by a core network device, where the indication information is used to indicate the IoT service area.

The access network device can determine the IoT service area corresponding to at least one IoT service, configure beams, auxiliary network nodes, etc. for the IoT service area, and then determine the UE that can serve as a reader in the IoT service area.

[0397] As shown in FIG10 , an embodiment of the present disclosure provides an information processing method, which is executed by a user equipment UE and includes:

[0398] Step 1001: Send at least one of the motion state information and auxiliary information of the UE to the access network device, wherein the auxiliary information is associated with the location of the UE, and wherein the motion state information and at least one of the auxiliary information are used by the access network device to determine whether to use the UE as a reader corresponding to the backscatter of the IoT service.

[0399] In one possible implementation, the access network device includes a base station.

[0402] In a possible implementation, the excitation signal may be sent by at least one of the following: a reader, an access network device, or an auxiliary network node (intermediate network node).

[0403] In one possible implementation, the IoT device includes at least one of the following: a tag device, a sensor device, etc.

[0404] In one possible implementation, the IoT device is configured to send a backscattered signal based on an excitation signal.

[0405] In a possible implementation, the frequency band of the excitation signal belongs to the frequency band of cellular mobile communications.

[0406] In one possible implementation, the excitation signal may provide energy for backscattering to the IoT device.

[0407] In one possible implementation, the motion state information may be used to at least determine the motion state of the UE. The motion state of the UE may include: stationary, moving, etc.

[0408] In a possible implementation, the auxiliary information associated with the location of the UE may be used to indicate the location of the UE, or to determine the location of the UE.

[0409] In one possible implementation, the access network device receives motion state information and / or auxiliary information sent by the UE, where the auxiliary information is associated with the location of the UE, and determines whether to use the UE as a backscatter reader corresponding to the IoT service based on at least one of the motion state information and the auxiliary information.

[0410] In one possible implementation, the access network device receives the auxiliary information sent by the UE and receives the motion state information sent by the core network device, and then determines whether to use the UE as a reader corresponding to the backscatter of the IoT service based on at least one of the motion state information and the auxiliary information.

[0411] In a possible implementation, the access network device receives the motion state information sent by the core network device, and determines whether to use the UE as a reader corresponding to the backscatter of the IoT service based on the motion state information.

[0412] Here, the motion state information and / or auxiliary information may be determined by the access network device, or may be sent to the access network device by other devices such as UE and / or core network device.

[0413] Due to the limitations of the signal characteristics (such as signal strength) of the backscattered signals emitted by IoT devices, in order for the reader to receive the backscattered signals and analyze the information carried by the backscattered signals, there are certain requirements for the distance between the reader and the IoT device, the position of the reader, and / or the motion state of the reader.

[0414] For example, the distance between the reader and the IoT device needs to be less than a predetermined distance.

[0415] For example, when the UE acts as a reader, the UE should reside on a cell that has overlapping coverage with the target area (such as the area where the IoT device is located).

[0416] The access network device can determine whether the UE can receive the backscatter signal sent by the IoT device based on the motion state information and / or auxiliary information. The access network device can determine whether the excitation signal sent by the UE can be used to trigger the IoT device to send the backscatter signal and / or determine whether the energy provided by the excitation signal sent by the UE can be used to trigger the IoT device to send the backscatter signal based on the motion state information and / or auxiliary information.

[0417] In this way, the access network device can determine whether the UE can act as a reader based on the motion state information and / or auxiliary information. This ensures that the determined reader can meet the communication requirements with the IoT device and reduces the high cost of deploying the access network device as a reader.

[0418] In some embodiments, the UE is at least one of the following:

[0419] UE with the capability to act as a reader;

[0420] UE authorized as a reader;

[0421] A UE that expects or agrees to act as a reader.

[0422] Here, the access network device determines that a UE capable of acting as a reader must have reader capabilities and / or be authorized as a reader by the network (e.g., core network equipment), and / or the UE desires or agrees to act as a reader. The access network device may first select a UE that meets the above conditions and, among the UEs that meet the above conditions, determine whether the UE can act as a reader based on the UE's motion state information and / or auxiliary information.

[0423] In a possible implementation, the UE may send the dynamic status information and / or the auxiliary information to the access network device in the RRC connected state.

[0424] In a possible implementation, the UE may send its own motion state to the core network device during or after the access process. The core network device may send the UE's motion state information to the access network device.

[0425] In some embodiments, the access network device receives the subscription information of the UE associated with the IoT service sent by the core network device, wherein the subscription information includes: the motion status information.

[0426] In one possible implementation, after accessing the network, a UE can sign up as a reader. The UE can report its motion status to a core network device. The core network device can send the UE's subscription information to the access network device, and the subscription information can include motion status information.

[0427] In some embodiments, the motion state information indicates that the UE is in a predetermined motion state, and the access network device determines the UE as the reader.

[0428] In a possible implementation, the predetermined motion state may include, but is not limited to: a stationary state, and a moving speed less than a predetermined moving speed threshold.

[0429] For example, for fast and low-cost network deployment, the UE may be specially designed or used as a reader. The UE may be in a predetermined motion state and subscribed as a reader.

[0430] In this way, by determining the UE's motion state, it is determined whether the UE can meet the communication needs of the IoT device, thereby improving the accuracy of reader selection; at the same time, it reduces the high cost of deploying access network equipment as a reader.

[0431] In some embodiments, the subscription information of the UE associated with the IoT service includes the motion status information.

[0432] For example, during the registration process of the UE to the network, the UE may sign up as a reader for IoT services and indicate that the UE is stationary.

[0433] Access network equipment can obtain UE's subscription information from core network equipment, and then determine the UE's motion status and determine whether to use the UE as a reader for IoT services.

[0434] In some embodiments, the contract information is used to indicate at least one of the following:

[0435] The UE is a reader corresponding to the backscatter of the IoT service;

[0436] The identifier of the IoT service;

[0437] The location information of the UE.

[0438] The subscription information may indicate that the UE is a reader of the backscatter corresponding to the IoT service, and indicate the identifier of the IoT service. The access network device determines the UE as a reader of the IoT service corresponding to the identifier of the IoT service.

[0439] The access network equipment can also determine the location of the UE based on the contract information.

[0440] In a possible implementation, the location information of the UE may be geographical location information, such as latitude and longitude information, geographical area information, etc.

[0441] In a possible implementation, the location information of the UE may be network location information, indicating the cell to which the UE belongs, etc.

[0442] Exemplarily, when the UE enters the RRC connected state, the core network device pushes the above-mentioned subscription information to the access network device. The subscription information may include the UE ID. The gNB may configure the UE as a reader based on the core network indication information.

[0443] In some embodiments, the auxiliary information is used by the access network device to determine the location of the UE and, in combination with the IoT service area corresponding to the IoT service, determine whether to determine the UE as the backscatter reader of the IoT service.

[0444] The IoT service area corresponding to the IoT service includes but is not limited to at least one of the following:

[0445] The region where the IoT device is located;

[0446] Areas where the distance to the IoT device is less than and / or equal to the distance threshold.

[0447] When the UE is in the IoT service area, the IoT device can send a backscattered signal based on the excitation signal sent by the UE, and the UE can receive the backscattered signal and correctly interpret the information carried by the backscattered signal.

[0448] In one possible implementation, when the UE is in an IoT service area, when the excitation signal sent by the UE reaches the IoT device, the signal quality of the excitation signal is greater than or equal to a predetermined excitation signal quality.

[0449] In one possible implementation, when the UE is in an IoT service area, when a backscatter signal sent by an IoT device reaches the UE, the signal quality of the backscatter signal is greater than or equal to a predetermined backscatter signal quality.

[0450] Exemplarily, when the UE enters the RRC connected state, the base station learns that the UE is capable of supporting becoming a reader and that the UE has been authorized to become a reader (or that the UE is willing to become a reader). The base station configures the UE to report location information (i.e., auxiliary information). The location information can be a precise location, or a location determined based on signal measurement (e.g., RSRP measurement of a co-frequency neighboring cell). After the UE reports its location, the base station determines whether the UE can become a reader based on the location information reported by the UE and the location information about the IOT service area pushed by the core network device. If so, the UE is configured to become a reader.

[0451] In this way, by determining the UE's location, it is determined whether the UE can meet the communication needs of the IoT device, thereby improving the accuracy of reader selection; at the same time, the high cost of deploying access network equipment as a reader is reduced.

[0452] In some embodiments, the auxiliary information includes: area identification information sent by the auxiliary network node and received by the UE, wherein the area identification information is used to identify an IoT service area, and the auxiliary network node is associated with the IoT service area.

[0453] Here, as shown in FIG6 , the auxiliary network node may be between the access network device and the IoT device, responsible for receiving uplink data or sending downlink DL data.

[0454] In one possible implementation, the auxiliary network node is associated with an IoT service area of ​​an IoT service, including but not limited to one of the following:

[0455] The auxiliary network node is within the IoT service area;

[0456] The predetermined wireless signals sent by the auxiliary network nodes can cover the IoT service area.

[0457] In one possible implementation, based on the area identification information, the IoT service area where the UE is located can be determined, and the access network device can then determine whether to configure the UE as a reader.

[0458] In some embodiments, the region identification information is used to indicate at least one of the following:

[0459] The frequency of the wireless signal in the IoT service area;

[0460] The IoT service area is associated with an identifier of the IoT service;

[0461] The identifier of the auxiliary network node.

[0462] The area identification information can be used by the UE or access network equipment to determine the IoT service area where the UE is located.

[0463] The UE may determine whether the predetermined wireless signal is a signal that needs to be measured based on the signal indication information, and determine the IoT service corresponding to the predetermined wireless signal, etc.

[0464] In some embodiments, the IoT service area indicated by the area identification information is used by the access network device to determine whether to use the UE as the reader.

[0465] Here, the access network device can determine whether to determine the UE as a reader of the IoT service area associated with the area identification information based on the UE's capabilities.

[0466] In a possible embodiment, the access network device may determine, in combination with the subscription information of the UE, whether to determine the UE as a reader of the IoT service area associated with the area identification information.

[0467] For example, when the UE's subscription information indicates that the IoT service the UE has subscribed to is the same as the IoT service in the IoT service area indicated by the area identification information, the access network device can determine the UE as a reader of the IoT service area associated with the area identification information.

[0468] In this way, by determining the IoT service area indicated by the auxiliary information received by the UE, the IoT service area in which the UE is located is determined, and then whether the UE can meet the communication needs of the IoT device is determined, thereby improving the accuracy of reader selection; at the same time, reducing the high cost of deploying access network equipment as a reader.

[0469] As shown in FIG11 , an embodiment of the present disclosure provides an information processing method, which is executed by a UE and includes:

[0470] Step 1101: Send a first measurement result to the access network device, where the first measurement result is obtained by the UE performing a first wireless signal measurement on a predetermined wireless signal, and the predetermined wireless signal carries the area identification information; wherein the first measurement result is used by the access network device to determine whether to send a measurement indication to the UE, and the measurement indication is used to instruct the UE to receive the area identification information.

[0471] The area identification information may be broadcast by the secondary group network node.

[0472] In a possible implementation, the access network device may configure the UE to measure the predetermined wireless signal.

[0473] In a possible implementation, the first radio signal measurement may be, but is not limited to, RRM measurement.

[0474] In one possible implementation, when the first measurement result is greater than a first measurement result threshold, the access network device sends a measurement indication to the UE. The first measurement result being greater than the first measurement result threshold may determine that the UE is close to the secondary group network and can communicate with the IoT device.

[0475] In one possible implementation, the measurement indication may indicate at least one of the following: a frequency of a predetermined wireless signal; an identifier of the IoT service; or an identifier of the auxiliary network node. The UE may determine a signal to be measured based on the measurement indication.

[0476] In some embodiments, the auxiliary information includes: a second measurement result determined by the UE performing a second wireless signal measurement on each of the N beams, wherein the beam is associated with the IoT service area of ​​the IoT service; wherein N is a positive integer greater than or equal to 1.

[0477] As shown in FIG8 , the beam is associated with the IoT service area of ​​the IoT service, including but not limited to the following:

[0478] Beams specifically configured for IoT service areas

[0479] The beam points to the IoT service area;

[0480] The beam and IoT service area have overlapping areas;

[0481] The relative position of the UE and the IoT service area can be determined by measuring the beam.

[0482] In some embodiments, the second measurement result is one of the following:

[0483] A measurement value obtained by the UE performing the second radio signal measurement on each beam;

[0484] The sum of the measured value and a predetermined offset value.

[0485] In a possible implementation, the second measurement result may be a measurement value obtained by the UE performing a second radio signal measurement.

[0486] In a possible implementation, the second measurement result may be the sum of a measurement value obtained by the UE performing a second radio signal measurement and a predetermined offset value.

[0487] In one possible implementation, the predetermined offset value may include hysteresis.

[0488] In some embodiments, the measured value includes at least one of the following:

[0489] Reference signal received power RSRP;

[0490] Reference signal received quality RSRQ;

[0491] Signal to Interference and Noise Ratio SINR.

[0492] As shown in FIG8 , the UE can determine the relative position between the UE and the IoT service area by measuring N beams.

[0493] The access network device can configure N dedicated beams for the IoT service area. The access network device can indicate to the UE that N dedicated beams are configured for the IoT service area.

[0494] In one possible implementation,

[0495] In one possible implementation, the access network device may send a measurement configuration for measuring the second wireless signal. The measurement configuration may indicate at least one of the following:

[0496] Beam identification information, such as the beam identifier and the cell associated with the beam;

[0497] Second wireless signal measurement items: such as RSRP, etc.;

[0498] Second measurement result reporting method: event-based measurement reporting, or periodic measurement reporting, etc.

[0499] The second measurement result may be used for, but not limited to, at least one of the following:

[0500] Determine the location of the UE;

[0501] Determine the relative position of the UE to the IoT service area.

[0502] The access network device may determine the location of the UE based on the second measurement result, and determine whether the UE can serve as a reader for the IoT service corresponding to the IoT service area.

[0503] In this way, through the two measurement results, the access network device determines the IoT service area where the UE is located, and then determines whether the UE can meet the communication needs of the IoT device, improving the accuracy of reader selection; at the same time, reducing the high cost of deploying the access network device as a reader.

[0504] In some embodiments,

[0505] If at least one of the following conditions is met, the access network device determines the UE as a reader corresponding to the backscatter of the IoT service:

[0506] The statistical values ​​of the second measurement results corresponding to M beams of the N beams are greater than a statistical value threshold, where M is a positive integer less than or equal to N;

[0507] The second measurement result corresponding to each beam of the M beams is greater than the first threshold corresponding to each beam;

[0508] The second measurement results corresponding to the M beams are all greater than a second threshold.

[0509] In some embodiments,

[0510] If at least one of the following conditions is met, the access network device does not determine the UE as a reader corresponding to backscatter for the IoT service:

[0511] The statistical values ​​of the second measurement results corresponding to M beams of the N beams are less than or equal to the statistical value threshold, where M is a positive integer less than or equal to N;

[0512] The second measurement result corresponding to each beam of the M beams is less than or equal to the first threshold corresponding to each beam;

[0513] At least one of the second measurement results corresponding to the M beams is less than or equal to a second threshold.

[0514] In one possible implementation, the statistical value threshold may be determined based on a relative position to an IoT service area of ​​the IoT service. If the statistical value of the second measurement results corresponding to each of the M beams is greater than the statistical value threshold, it can be determined that the UE is within the IoT service area, and therefore, it can be determined that the UE can function as a reader.

[0515] In one possible implementation, the statistical value may include but is not limited to one of the following: a linear average; a weighted average.

[0516] In one possible implementation, a first threshold may be set for each beam. The first threshold may be determined based on the UE's relative position to the IoT service area. If the UE obtains a second measurement result for each beam and each second measurement result is greater than the first threshold corresponding to each beam, the UE may be determined to be within the IoT service area and, therefore, may be determined to be capable of functioning as a reader.

[0517] In one possible implementation, the M beams may use the same second threshold. The second threshold may be determined based on the UE's relative position to an IoT service area. If the second measurement results obtained by the UE in each of the M beams are all greater than the second threshold, the UE may be determined to be within the IoT service area, and therefore, the UE may be qualified as a reader.

[0518] The UE can measure all N beams or only M beams. The beams measured by the UE can be configured by the access network device or the core network device.

[0519] In some embodiments, the M beams are one of the following:

[0520] M beams configured by the access network device or core network device;

[0521] Among the N beams, M beams with higher second measurement results;

[0522] Among the N beams, M beams have second measurement results greater than a third threshold.

[0523] The access network device may determine that the UE is a reader. Due to the mobility of the UE, the access network device may also deconfigure the UE as a reader, that is, determine that the UE cannot be used as a reader.

[0524] In one possible implementation, if the statistical value of the second measurement results corresponding to the M beams is less than or equal to the statistical value threshold, it can be determined that the UE cannot meet the requirements of communicating with the IoT device in the IoT service area. Therefore, it can be determined that the UE cannot serve as a reader.

[0525] In one possible implementation, the UE obtains a second measurement result in each beam measurement, which is less than or equal to the first threshold corresponding to each beam. It can be determined that the UE cannot meet the requirements of communicating with the IoT device in the IoT service area. Therefore, it can be determined that the UE cannot be used as a reader.

[0526] In one possible implementation, the second measurement results measured by the UE in M ​​beams are all less than or equal to the second threshold. It can be determined that the UE cannot meet the requirements of communicating with the IoT device in the IoT service area. Therefore, it can be determined that the UE cannot be used as a reader.

[0527] In some embodiments, the core network device can send indication information indicating the IoT service area to the access network device. The access network device can determine the IoT service area corresponding to at least one IoT service, configure beams, auxiliary network nodes, etc. for the IoT service area, and then determine the UE that can serve as a reader within the IoT service area.

[0528] As shown in FIG12 , an embodiment of the present disclosure provides an information processing method, which is executed by a core network device and includes:

[0529] Step 1201: Sending motion state information of a user equipment (UE) to an access network device, wherein the motion state information is used by the access network device to determine whether to use the UE as a backscatter reader corresponding to an IoT service.

[0530] In a possible implementation, the access network device may include a base station, etc.

[0531] In one possible implementation, a reader in a backscatter transmission of an IoT service is configured to receive at least a backscatter signal sent by an ambient IoT device. In this embodiment, the ambient IoT device may be referred to as an IoT device.

[0532] In one possible implementation, the reader may also be used to send an excitation signal to the IoT device.

[0533] In a possible implementation, the excitation signal may be sent by at least one of the following: a reader, an access network device, or an auxiliary network node (intermediate network node).

[0534] In one possible implementation, the IoT device includes at least one of the following: a tag device, a sensor device, etc.

[0535] In one possible implementation, the IoT device is configured to send a backscattered signal based on an excitation signal.

[0536] In a possible implementation, the frequency band of the excitation signal belongs to the frequency band of cellular mobile communications.

[0537] In one possible implementation, the excitation signal may provide energy for backscattering to the IoT device.

[0538] In one possible implementation, the motion state information may be used to at least determine the motion state of the UE. The motion state of the UE may include: stationary, moving, etc.

[0539] In one possible implementation, the access network device may also combine the motion state information with the auxiliary information to determine whether the UE can be configured as a backscatter reader corresponding to the IoT service. The auxiliary information is associated with the UE's location.

[0540] In a possible implementation, the auxiliary information associated with the location of the UE may be used to indicate the location of the UE, or to determine the location of the UE.

[0541] In one possible implementation, the access network device receives motion state information and / or auxiliary information sent by the UE, where the auxiliary information is associated with the location of the UE, and determines whether to use the UE as a backscatter reader corresponding to the IoT service based on at least one of the motion state information and the auxiliary information.

[0542] In one possible implementation, the access network device receives the auxiliary information sent by the UE and receives the motion state information sent by the core network device, and then determines whether to use the UE as a reader corresponding to the backscatter of the IoT service based on at least one of the motion state information and the auxiliary information.

[0543] In a possible implementation, the access network device receives the motion state information sent by the core network device, and determines whether to use the UE as a reader corresponding to the backscatter of the IoT service based on the motion state information.

[0544] Here, the motion state information and / or auxiliary information may be determined by the access network device, or may be sent to the access network device by other devices such as UE and / or core network device.

[0545] Due to the limitations of the signal characteristics (such as signal strength) of the backscattered signals emitted by IoT devices, in order for the reader to receive the backscattered signals and analyze the information carried by the backscattered signals, there are certain requirements for the distance between the reader and the IoT device, the position of the reader, and / or the motion state of the reader.

[0546] For example, the reader movement speed needs to be less than a predetermined speed threshold, etc.

[0547] For example, the distance between the reader and the IoT device needs to be less than a predetermined distance.

[0548] For example, when the UE acts as a reader, the UE should reside on a cell that has overlapping coverage with the target area (such as the area where the IoT device is located).

[0549] The access network device can determine whether the UE can receive the backscatter signal sent by the IoT device based on the motion state information and / or auxiliary information. The access network device can determine whether the excitation signal sent by the UE can be used to trigger the IoT device to send the backscatter signal and / or determine whether the energy provided by the excitation signal sent by the UE can be used to trigger the IoT device to send the backscatter signal based on the motion state information and / or auxiliary information.

[0550] In this way, the access network device can determine whether the UE can act as a reader based on the motion state information and / or auxiliary information. This ensures that the determined reader can meet the communication requirements with the IoT device and reduces the high cost of deploying the access network device as a reader.

[0551] In some embodiments, the UE is at least one of the following:

[0552] UE with the capability to act as a reader;

[0553] UE authorized as a reader;

[0554] Agree to call UE a reader.

[0555] Here, the access network device determines that a UE capable of acting as a reader must have reader capabilities and / or be authorized as a reader by the network (e.g., core network equipment), and / or the UE desires or agrees to act as a reader. The access network device may first select a UE that meets the above conditions and, among the UEs that meet the above conditions, determine whether the UE can act as a reader based on the UE's motion state information and / or auxiliary information.

[0556] In some embodiments, when the motion state information indicates that the UE is in a predetermined motion state, the access network device determines the UE as the reader.

[0557] In some embodiments, the subscription information of the UE associated with the IoT service includes the motion status information.

[0558] In one possible implementation, after accessing the network, a UE can sign up as a reader. The UE can report its motion status to a core network device. The core network device can send the UE's subscription information to the access network device, and the subscription information can include motion status information.

[0559] In a possible implementation, the predetermined motion state may include, but is not limited to: a stationary state, and a moving speed less than a predetermined moving speed threshold.

[0560] For example, for fast and low-cost network deployment, the UE may be specially designed or used as a reader. The UE may be in a predetermined motion state and subscribed as a reader.

[0561] In this way, by determining the UE's motion state, it is determined whether the UE can meet the communication needs of the IoT device, thereby improving the accuracy of reader selection; at the same time, it reduces the high cost of deploying access network equipment as a reader.

[0562] For example, during the registration process of the UE to the network, the UE may sign up as a reader for IoT services and indicate that the UE is stationary.

[0563] Access network equipment can obtain UE's subscription information from core network equipment, and then determine the UE's motion status and determine whether to use the UE as a reader for IoT services.

[0564] In some embodiments, the contract information is used to indicate at least one of the following:

[0565] The UE is a reader corresponding to the backscatter of the IoT service;

[0566] The identifier of the IoT service;

[0567] The location information of the UE.

[0568] The subscription information may indicate that the UE is a reader of the backscatter corresponding to the IoT service, and indicate the identifier of the IoT service. The access network device determines the UE as a reader of the IoT service corresponding to the identifier of the IoT service.

[0569] The access network equipment can also determine the location of the UE based on the contract information.

[0570] In a possible implementation, the location information of the UE may be geographical location information, such as latitude and longitude information, geographical area information, etc.

[0571] In a possible implementation, the location information of the UE may be network location information, indicating the cell to which the UE belongs, etc.

[0572] Exemplarily, when the UE enters the RRC connected state, the core network device pushes the above-mentioned subscription information to the access network device. The subscription information may include the UE ID. The gNB may configure the UE as a reader based on the core network indication information.

[0573] As shown in FIG13 , an embodiment of the present disclosure provides an information processing method, which is executed by a core network device and includes:

[0574] Step 1301: Send indication information to the access network device, where the indication information is used to indicate the IoT service area, and the IoT service area is used for the access network device to determine whether to determine the UE as the reader corresponding to the backscatter of the IoT service.

[0575] Here, the core network device can send indication information indicating the IoT service area to the access network device. The access network device can determine the IoT service area corresponding to at least one IoT service, configure beams, auxiliary network nodes, etc. for the IoT service area, and then determine the UE that can serve as a reader in the IoT service area.

[0576] The access network device may determine whether the UE can be configured as a reader based on the IoT service area, the location of the UE, and / or auxiliary information, etc.

[0577] The specific implementation method in which the access network device determines whether the UE can be configured as a reader based on the IoT service area, combined with the UE's location and / or auxiliary information, is similar to the method shown in Figures 5 to 10 and will not be repeated here.

[0578] The following provides a specific example in combination with any of the above embodiments:

[0579] To quickly and cost-effectively deploy the passive IoT, this example proposes a passive IoT data collection method based on UEs as anchor points. However, selecting a suitable UE as a reader is a challenge. For example, a UE can only function as a reader when it is within the IoT service area (IoT service area). Furthermore, if a UE acting as a reader moves, for example, out of the IoT service area, a new UE must be selected as the reader.

[0580] This example present invention proposes multiple ways to select a suitable UE as a reader, as follows:

[0581] Method 1: UE reader is a stationary terminal

[0582] The selection of a UE as a reader should be based on UE capabilities and / or user consent. When a UE acts as a reader, UE location is also important. The UE should reside on a cell that has overlapping coverage with the target area. However, sometimes, the cell granularity may be too coarse.

[0583] For fast and low-cost network deployment, UE can be specially designed or used as a reader. Such UE can be stationary and such UE is contracted as a reader.

[0584] The UE subscription information includes information indicating that the UE is a dedicated reader and may also include the following information:

[0585] -UE as a reader is stationary (motion state information);

[0586] -UE subscription as a reader, associated IoT service information, and / or geographical area, such as a cell list or the UE's latitude and longitude information.

[0587] When the UE enters the RRC connected state, the core network (CN) pushes the above subscription information and / or UE identification (ID) information to the gNB. The gNB can configure the UE as a reader based on the core network indication information.

[0588] Method 2: Determine whether to select as a reader based on UE location reporting

[0589] 1) When the UE enters the RRC Connected state, the gNB learns that the UE is capable of becoming a reader and has been authorized to do so (i.e., the UE is willing to act as a reader). The gNB configures the UE to report location information (auxiliary information). This location information can be precise location information or a location fingerprint determined based on radio signal measurements (e.g., RSRP measurements of co-frequency neighboring cells).

[0590] 2) After the UE reports its location, the base station determines whether the UE can become a reader based on the location information reported by the UE and the location information about the IoT service area pushed by the CN. If so, the base station configures the UE to become a reader.

[0591] Method 3: Determine whether to select the UE as a reader based on the auxiliary network node

[0592] 1) Assuming that an auxiliary network node exists in the network deployment, if the UE is capable of supporting the function of a reader and has been authorized to do so (i.e., the UE is willing to act as a reader), the gNB will configure the UE to monitor information (predetermined radio signals) broadcast by the auxiliary network node. Optionally, before configuring the UE to monitor the information broadcast by the auxiliary network node, the gNB may configure the UE to report RRM measurement (first radio signal measurement) results (first measurement results), and based on the RRM measurement reports, determine whether to issue the configuration (measurement indication). The information broadcast by the auxiliary network node may include frequency information, IoT service identification information, auxiliary network node ID information, etc.

[0594] 3) After the UE obtains the information of the auxiliary network node (area identification information), it reports this information to the gNB;

[0595] 4) The gNB will configure the UE as a reader based on the UE’s report.

[0596] Method 4: Determine whether to select the UE as a reader based on the IoT service area’s dedicated beam measurement report

[0597] 1) Based on the service area information about the IoT service pushed by the core network, the base station configures a dedicated beam set (N beams) for the IoT service area.

[0598] 2) The base station configures RRM measurement (second radio signal measurement) for UE that is capable of supporting becoming a reader and has been authorized to become a reader (i.e., the UE is willing to become a reader). The measurement object is the above-mentioned beam set, and the cell described in the specified beam in the measurement object configuration is the serving cell or cell ID. The measurement report type can be event-based measurement report or periodic measurement report. The measurement event can include one of the following:

[0599] Option 1: The linear average of all beam measurement results in the beam set is greater than a threshold configured on the network side. Alternatively, the linear average of all beam measurement results is greater than a threshold configured on the network side. The measurement quantity can be RSRP, and / or RSRQ, and / or SINR.

[0600] Option 2: The measurement results of one or more beams in the beam set are greater than the beam-specific threshold configured by the network;

[0601] Option 3: Any one or more beams in the beam set meet a threshold greater than the pre-configured threshold on the network side;

[0602] The above measurement events can take into account hysteresis, bias, etc. That is, the trigger condition is met only when the measurement result + hysteresis / bias is greater than the network pre-configured threshold.

[0603] 3) Based on the UE's measurement report for the beam set, the base station determines whether to configure the UE as a reader.

[0604] 4) If the measurement for the beam set meets the leave condition, the UE is configured as a reader. The leave condition can be:

[0605] Option a: The linear average of all beam measurement results in the beam set is less than a threshold configured on the network side. Alternatively, the linear average of all beam measurement results is less than a certain threshold configured on the network side. The measurement quantity can be RSRP, and / or RSRQ, and / or SINR.

[0606] Option b: The measurement results of one or more beams in the beam set are less than the beam-specific threshold configured by the network;

[0607] Option c: Any one, several, or all beams in the beam set meet a threshold smaller than the pre-configured threshold on the network side;

[0608] The UE-assisted selection or deselection of UE as a reader, i.e., the selection and reselection of UE readers, enables fast and low-cost deployment of passive IoT.
