Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0216] In some cases, IoT devices in IoT networks are often powered by traditional batteries with limited lifespans, negatively impacting user experience. The astronomical growth of IoT networks, coupled with the proliferation of IoT devices, has pushed maintenance expenses, including labor and battery costs, to a whole new level. Billions of traditional batteries are discarded each year, with only a small fraction effectively recycled, negatively impacting the Earth's ecosystem. Maintaining IoT network operations and replacing batteries can be extremely challenging in extreme environmental conditions. Battery-free IoT communications have been proposed to improve network performance and sustainability, expanding their application scenarios. Furthermore, battery-free communications are more environmentally friendly and safer for children and the elderly. Eliminating traditional batteries significantly reduces device size and cost, paving the way for a variety of new applications.

[0217] In some embodiments, in the era of the fifth generation mobile communication technology 5G, various low power wide area (LPWA) technologies have been developed, such as machine type communication (MTC), narrowband Internet of Things (NB-IoT), reduced capability (RedCap), etc., to meet the growing needs of vertical fields. These LPWA technologies achieve low cost, low power consumption and large-scale connectivity, which can meet the requirements of many applications. However, there are still many use cases and applications that cannot be solved in the following situations. First, devices driven by traditional batteries are not applicable, such as in extreme environmental conditions (such as high voltage, extremely high / low temperature, humid environment). Second, maintenance-free equipment is required (for example, there is no need to replace traditional batteries of the device). Finally, ultra-low complexity, very small device size / form factor (such as mm thickness), longer life cycle, etc. are required.

[0218] In some embodiments, ambient powered IoT is a promising technology that can address the unmet needs described above. An ambient powered IoT device is an IoT device that is 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.

[0219] In some embodiments, energy harvested from the environment can drive data transmission and wireless communications among sensor nodes. Current mainstream low-power IoT communication chips consume tens or even hundreds of milliwatts of power for both transmission and reception, while ambient energy harvesting only captures microwatts, making them inadequate for powering these nodes. Therefore, new wireless communication technologies are needed to reduce communication energy consumption to tens or even below ten microwatts. Backscatter communications, currently a mainstream approach, is a key technology for building a green, energy-efficient, and flexibly deployable future IoT, and a crucial means of achieving the "Intelligent Connection of Everything."

[0220] In some embodiments, please refer to Figure 1b. Backscatter communication is a modulation and transmission technology designed with extremely low power consumption, which utilizes the principle of backscattering of radio frequency signals. Backscatter communication was first proposed by Stockman. When the radio frequency signal reaches the surface of an object, a part of it will be reflected. The sending node adjusts the matching between the receiving antenna and the impedance according to the information to be sent, thereby enhancing the reflection of the incident radio frequency signal and modulating the perception data acquired by itself onto the reflected signal to complete the transmission of the data. This process is similar to that of a reflector. Compared with other communication technologies, backscatter communication does not require a complex radio frequency structure, reduces the use of devices such as power amplifiers, high-precision crystal oscillators, duplexers, and high-precision filters, and does not require complex baseband processing. Therefore, it can simplify terminal design and significantly reduce the cost of terminal nodes.

[0221] In some embodiments, backscatter communication has been widely used in Radio Frequency Identification (RFID) systems, resulting in numerous large-scale commercial applications. Its operating principle is that a receiver (typically an RFID reader) transmits a radio frequency excitation signal, activating a passive node (typically an RFID tag). The tag then uses backscatter communication to modulate its information onto the radio frequency signal. The reader then receives the reflected signal from the passive tag and demodulates it, achieving information transmission.

[0222] In some embodiments, RFID technology also has numerous drawbacks, such as limited coverage (the wireless signal experiences double-path fading during the round-trip communication process, resulting in high path loss and a short effective communication range), single-channel transmission, the need for strict tag alignment, and a lack of power control. RFID technology still has significant room for improvement in communication. Integration with 3GPP communication technologies is needed to improve the wireless communication performance of RFID technology in the passive IoT.

[0223] The expected new type of IoT devices have the characteristics of low memory, low processing power, low power consumption, small data transmission, and massive deployment. Environmental IoT devices can be maintenance-free and have a long service life (for example, more than 10 years).

[0224] These new IoT devices require energy from radio waves transmitted by network nodes to power themselves. Therefore, until they receive energy, they are typically powered off, meaning they are disconnected from the network. To address this, the communication system must support data communication methods with shorter transmission times, lower memory consumption, and more convenient terminal management to expedite data communication.

[0225] In some embodiments, see FIG1c, which shows a network architecture for wireless communication based on ambient energy devices using backscatter technology.

[0226] Architecture 1: Direct downlink (DL) and uplink (UL) data reception and transmission between ambient power IoT devices and base stations.

[0227] Architecture 2: DL and UL data reception and transmission are performed indirectly between the ambient IoT and the base station; intermediate nodes exist in the middle to forward data. For example, the intermediate nodes can be relays, integrated access backhaul (IAB), UEs, and repeaters.

[0228] Architecture 3: Ambient IoT and the base station directly transmit or receive data in the DL or UL. Auxiliary nodes are located on the UL or DL, responsible for receiving or sending UL or DL ​​data. Examples of auxiliary nodes include relays, IABs, UEs, and repeaters.

[0229] Architecture 4: Direct DL and UL data reception and transmission between ambient IoT and UE; UE is responsible for collecting data and forwarding it to the network.

[0230] In some embodiments, referring to FIG1d , Ambient IoT devices can be divided into three types:

[0231] Device A: No energy storage, no independent signal generation / amplification, i.e. backscatter transmission;

[0232] Device B: has energy storage but no independent signal generation, i.e., backscatter transmission. The use of stored energy may include amplification of the reflected signal.

[0233] Device C: has energy storage and independent signal generation, i.e., active RF components for transmission.

[0234] In some embodiments, to support data transmission of A-IoT devices, the network needs to support the following functions:

[0235] The function as an energy source (ES) is only used for equipment types B and C;

[0236] Downlink transmission (DT) function, used to send indication information to A-IoT devices, thereby triggering uplink transmission of A-IoT devices;

[0237] As an excitation (CW, Continuous Wave) function, it is only used by Devices A and B. A-IoT devices achieve uplink transmission by backscattering CW. CW is actually a type of ES, and A-IoT devices can receive CW and store energy.

[0238] The uplink receive (UR) function receives uplink information backscattered by the A-IoT device, or receives uplink information actively transmitted by the A-IoT device.

[0239] The device that performs the above-mentioned ES, DT, CW or UR functions may be a UE, a repeater, a relay or a base station, etc.

[0240] In some embodiments, a device may only support one of the above functions.

[0241] In some embodiments, a device may also support multiple of the above functions simultaneously.

[0242] In some embodiments, a device may also support all of the above functions simultaneously.

[0243] In some embodiments, two topology scenarios are supported. As shown in Figure 1e , one topology scenario involves a direct connection between an ambient IoT base station (or reader) and an ambient IoT device (or tag). As shown in Figure 1f , the other topology scenario involves a connection between an ambient IoT device and a UE, with the UE acting as an intermediate node in the base station.

[0244] In some embodiments, the spectrum resources available for Ambient IoT communications support three deployment modes: in-band, guard band, and stand-alone. In-band uses normal NR communication DL and / or UL spectrum resources; guard-band uses the guard band of the normal NR communication DL and / or UL spectrum; and stand-alone uses spectrum resources unrelated to NR communications.

[0245] In some embodiments, in the topology shown in FIG1f, a UE in a non-connected state (RRC_IDLE / INACTIVE) needs to receive paging messages, receive system broadcast information, and perform radio resource management (RRM) operations while completing ambient IoT deployment. When necessary (uplink traffic arrives, or paging is received, i.e., downlink traffic arrives), a random access process will be triggered to enter the radio resource control (RRC) connected state. During the cell selection and reselection process, the RRC_IDLE / INACTIVE UE relies on RRM measurements and frequency priority configuration to select the target cell for cell reselection. The current NR deployment is a multi-layer hybrid network of macro cells and micro cells. For example, macro cells are mainly for coverage, and micro cells are mainly for capacity. Therefore, when a terminal that supports ambient IoT operations resides in a cell that does not support ambient IoT operations, such as a micro cell, when selecting a cell to reselect, when the macro cell needs to find the UE as a reader, the macro cell will not be able to find the UE as a reader because the terminal resides in the micro cell.

[0246] In the related art, it is necessary to make UEs supporting ambient IoT reside in macro cells supporting ambient IoT operations as much as possible, so that when the network needs to use the UE as a reader, more suitable terminals can be found. However, when there is no ambient IoT operation requirement, the network side load balancing requirement needs to be met as much as possible.

[0247] FIG2a is an interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG2a, the present disclosure embodiment relates to a communication method for a communication system 100, the method comprising:

[0248] Step S2101: The terminal obtains first information.

[0249] In some embodiments, the access network device sends the first information to the terminal.

[0250] In some embodiments, the terminal receives the first information sent by the access network device, thereby obtaining the first information.

[0251] In some embodiments, the terminal receives system broadcast information sent by the access network device, and the system broadcast information includes the first information.

[0252] In some embodiments, the terminal receives radio resource control RRC signaling sent by the access network device, and the RRC signaling includes the first information.

[0253] Exemplarily, for a terminal that supports and / or agrees to participate in the AIOT operation of an execution environment IoT device, if the terminal is in an RRC connected state, if the access network device obtains information about the terminal's ability to support AIOT and / or user consent information that the terminal agrees to act as a Reader, the access network device will configure in the RRC signaling the dedicated frequency priority (i.e., the first information) to be used after the terminal enters the RRC non-connected state.

[0254] In some embodiments, the terminal determines the first information based on a predetermined communication protocol, thereby obtaining the first information.

[0255] In some embodiments, the terminal supports and / or agrees to participate in performing ambient IoT (AIOT) operations.

[0256] Exemplarily, performing an AIOT operation may be an operation of reading AIOT data. For example, a terminal may be configured as a reader in the IOT, and after being configured as a reader, AIOT data may be read. The reader may be a radio frequency identification (RFID) module. It should be noted that a reader may also be referred to as a receiver. In the embodiments of the present disclosure, "reader" and "receiver" are interchangeable and are not limited herein.

[0257] In some embodiments, the first information is used to indicate the frequency priority of the cell that the terminal can camp in. In some scenarios, the first information may also be referred to as "frequency priority configuration information" or "frequency priority configuration", which is not limited here.

[0258] In some embodiments, the cell in which the terminal can camp may be determined based on predetermined communication protocol information. Exemplarily, the predetermined communication protocol information indicates the cell in which the terminal can camp.

[0259] For example, the cells that the terminal can reside in are A, B and C. Corresponding frequency priorities can be set for A, B and C respectively. If the frequency priority of cell A is higher than the frequency priorities of cells B and C, the terminal will prioritize residing in cell A.

[0260] In some embodiments, the terminal receives indication information sent by the network device, and the indication information indicates the cells in which the terminal can reside. For example, the indication information indicates that the cells in which the terminal can reside are A, B and C. Corresponding frequency priorities can be set for A, B and C respectively. If the frequency priority of cell A is higher than the frequency priority of cells B and C, the terminal will preferentially reside in cell A.

[0261] It should be noted that priorities may be set for all cells that can be camped on, or for some of the cells that can be camped on, which is not limited here.

[0262] It should be noted that the frequency priority can be the priority of the detection frequency corresponding to the cell. For example, the detection frequency corresponding to the first cell is the first frequency, and the detection frequency corresponding to the second cell is the second frequency. If the priority of the first frequency is higher than the priority of the second frequency, the first frequency will be detected first, that is, the first cell will be detected first, and thus the first cell will be prioritized for resident, so that the first cell can be preferentially selected or reselected.

[0263] In some embodiments, the cell includes a first cell supporting AIOT operation and a second cell not supporting AIOT operation, and the frequency priority corresponding to the first cell is higher than the frequency priority corresponding to the second cell.

[0264] In some embodiments, the first information includes at least one of the following:

[0265] Information on priorities associated with frequency layers;

[0266] Second information, where the second information is used to indicate whether the frequency layer supports or does not support the AIOT operation;

[0267] Information about a timer associated with the effective period of the frequency priority;

[0268] Information associated with the effective area of ​​the frequency priority.

[0269] In some embodiments, the information of priorities associated with frequency layers may indicate a priority associated with each frequency layer.

[0270] In some embodiments, each cell may be associated with a frequency layer. For example, each cell may correspond to a frequency band (which may correspond to a frequency interval) in the associated frequency layer. The frequency priority corresponding to the cell in which the terminal can reside may be the priority of the associated frequency layer. For example, if the frequency priority corresponding to the frequency layer associated with cell A in which the terminal can reside is L1, then the frequency priority of cell A in which the terminal can reside is L1.

[0271] For example, the frequency layers associated with cell A, cell B, and cell C are frequency layer 1, frequency layer 2, and frequency layer 3, respectively, and the priorities corresponding to each frequency layer are L1, L2, and L3, respectively. If the cell in which the terminal can reside is cell A, the frequency priority corresponding to cell A is the priority L1 of frequency layer 1.

[0272] In some embodiments, the priority information associated with the frequency layers may indicate a sub-priority associated with each frequency layer.

[0273] In some embodiments, if the frequency layer supports AIOT operation, the cell associated with the frequency layer supports AIOT operation; if the frequency layer does not support AIOT operation, the cell associated with the frequency layer does not support AIOT operation.

[0274] In some embodiments, the information of the timer associated with the effective period of the frequency priority may include a timing time. A timer may be set for each frequency priority. The timing time of the timer may be the time when the corresponding frequency priority takes effect. The frequency priority is valid only within this timing time.

[0275] In some embodiments, the timer time can be the effective period, and the frequency priority is effective during the timer time. For example, if the frequency priority of frequency A is level N and the timer time is T, then within T, the frequency priority of frequency A is level N. If the timer time expires and exceeds T, the frequency priority of frequency A is no longer level N.

[0276] In some embodiments, the timing time of the timer can be a duration, or a start time and an end time. For example, the start time is 1:00 and the end time is 1:03, corresponding to a duration of 3 minutes, which is not limited here.

[0277] In some embodiments, the information associated with the effective area of ​​the frequency priority may include an effective area. An effective area may be set for each frequency priority. The frequency priority is valid only when the terminal is within the effective area.

[0278] In some embodiments, the effective area may be the area where a cell is located. For example, the effective area may include multiple cells. As long as the terminal is determined to be within the multiple cells (and has established a connection with the access network devices corresponding to the cells), the terminal is determined to be within the effective area. For example, if the effective area includes cell A and the terminal has established a connection with cell A, then the terminal is within the effective area. If the terminal is within the effective area, the frequency priority is valid. If the terminal moves out of the effective area, the frequency priority becomes invalid.

[0279] Step S2102: The terminal determines whether the first information is valid or invalid.

[0280] In some embodiments, if the terminal receives the first information, the terminal determines that the first information is valid.

[0281] Exemplarily, once a terminal that supports and / or agrees to participate in the execution of AIOT operations of an environment IoT device receives the first information, it determines that the first information is effective.

[0282] In some embodiments, after acquiring the first information, if the terminal switches to an RRC non-connected state, the terminal determines that the first information is effective. Here, the RRC non-connected state is an RRC idle state or an RRC inactive state.

[0283] In some embodiments, the terminal receives third information sent by the access network device, and the third information is used to make the first information effective; if the terminal receives the third information, the terminal determines that the first information is effective.

[0284] Exemplarily, the third information may be activation indication information or validation indication information.

[0285] In some embodiments, the terminal receives system broadcast information sent by the access network device, and the system broadcast information includes the third information.

[0286] In some embodiments, the terminal receives downlink control information (DCI) sent by the access network device, and the DCI information includes the third information.

[0287] In some embodiments, the DCI may be a paging DCI.

[0288] In some embodiments, the DCI may be scrambled by a System Information Radio Network Temporary Identifier (SI-RNTI).

[0289] In some embodiments, the DCI may be scrambled by a newly defined Radio Network Temporary Indentifier (RNTI).

[0290] In some embodiments, if the terminal is within a first area, the terminal determines that the first information is effective.

[0291] In some embodiments, if the first information is valid, the terminal starts a first timer, the timing of the first timer is the validity time of the detection frequency priority. If the first timer times out, the terminal determines that the first information is invalid.

[0292] In some embodiments, the terminal receives fourth information sent by the access network device, where the fourth information is used to indicate that the first information is invalid; if the terminal receives the fourth information, the terminal determines that the first information is invalid.

[0293] Exemplarily, the fourth information may be deactivation indication information or invalidation indication information.

[0294] In some embodiments, the terminal receives system broadcast information sent by the access network device, and the system broadcast information includes the fourth information.

[0295] In some embodiments, the terminal receives downlink control information DCI sent by the access network device, and the DCI information includes the fourth information.

[0296] In some embodiments, the DCI may be a paging DCI.

[0297] In some embodiments, the DCI may be scrambled by a System Information Radio Network Temporary Identifier (SI-RNTI).

[0298] In some embodiments, the DCI may be scrambled by a newly defined Radio Network Temporary Indentifier (RNTI).

[0299] In some embodiments, if the terminal completes cell reselection, the terminal determines that the first information is invalid.

[0300] In some embodiments, if the terminal reselects a cell that does not support AIOT, the terminal determines that the first information is invalid.

[0301] In some embodiments, if the system broadcast information does not include the first information, the terminal determines that the first information is invalid.

[0302] In some embodiments, the terminal receives a paging DCI. If the first information field carried in the paging DCI indicates a change or deconfiguration of the frequency priority, the terminal determines that the first information is invalid.

[0303] In some embodiments, the terminal receives a paging DCI. If the first information field carried in the paging DCI indicates a configured frequency priority, the terminal determines that the terminal can obtain the first information.

[0304] In some embodiments, if the terminal is not in the first area, the terminal determines that the first signal is invalid.

[0305] In some embodiments, if the first information is invalid, the stored first information is released (may be deleted).

[0306] In some embodiments, the terminal receives fifth information sent by the access network device. If the first information fails, the terminal performs cell selection or reselection based on the fifth information; wherein the fifth information indicates the common frequency priority of the cell in which the terminal can reside. Here, the common frequency priority can be the shared frequency priority configured in the system broadcast information.

[0307] It should be noted that if the first information is invalid, the terminal will ignore the public frequency priority information carried in the system broadcast information.

[0308] Step S2103: The terminal adjusts the frequency priority.

[0309] It should be noted that, in the technical solution disclosed herein, step S2103 may be a non-essential step, that is, after the terminal obtains the first information and determines the corresponding frequency priority of the cell in which the terminal can reside based on the first information, the cell selection or reselection can be performed based on the corresponding frequency priority indicated by the first information, without adjusting the frequency priority based on the frequency priority indicated by the first information and performing cell selection or reselection based on the adjusted frequency priority.

[0310] In some embodiments, adjusting the frequency priority may be adjusting the frequency priority of a cell where the terminal can reside with a high level to a frequency priority of a low level, or may be adjusting the frequency priority of a cell where the terminal can reside with a low level to a frequency priority of a high level.

[0311] Exemplarily, the frequency priority corresponding to cell A where the terminal can reside indicated by the first information is L1 (corresponding to high priority), and the terminal can adjust the frequency priority corresponding to cell A from frequency priority L1 to frequency priority L2 (corresponding to low priority).

[0312] In some embodiments, the terminal receives sixth information sent by the access network device. If the terminal receives the sixth information in a third cell, the terminal adjusts the frequency priority corresponding to the third cell to the highest priority; wherein the sixth information is used to indicate the network's ability to support AIOT operations.

[0313] In some embodiments, the third cell may be the cell where the terminal is currently located, for example, the third cell may be the cell with which the terminal establishes an RRC connection. It should be noted that the third cell may be the first cell or the second cell, but is not limited thereto.

[0314] For example, if the UE obtains capability indication information indicating that the network supports AIOT operations from the network side, the UE considers that the frequency corresponding to the cell has the highest priority.

[0315] In some embodiments, if the terminal receives the sixth information in the third cell, the terminal adjusts the frequency priority corresponding to the third cell to the highest priority; wherein the sixth information is used to indicate the configuration parameters for the terminal to perform AIOT operations.

[0316] For example, if the UE obtains configuration information for becoming a reader from the network side and enters the RRC idle state or the RRC inactive state, the UE considers that the frequency priority of the current cell is the highest.

[0317] In some embodiments, if the terminal receives the sixth information in the third cell, the terminal adjusts the frequency priority corresponding to the third cell to the highest priority; wherein the sixth information is used to indicate the triggering of the start of the AIOT operation.

[0318] Exemplarily, if the UE obtains first indication information from the third cell, where the first indication information is used to instruct the terminal to start performing the AIOT operation, the UE considers that the frequency of the third cell has the highest priority.

[0319] Exemplarily, if the terminal obtains the second indication information from the network side, and the second indication information is used to instruct the network to select the terminal as the reader performing the AIOT operation, the UE considers that the frequency where the third cell is located has the highest priority.

[0320] In this way, the terminal preferentially selects the third cell to camp on during the subsequent camping process.

[0321] In some embodiments, if the terminal receives sixth information in the third cell, the terminal adjusts the frequency priority corresponding to the third cell to the highest priority; wherein the sixth information is used to indicate that the terminal is selected as a Reader.

[0322] In some embodiments, if the frequency priority corresponding to the third cell is adjusted to the highest priority, a second timer is started; and when the terminal determines that the second timer has timed out, the terminal releases the highest priority of the frequency priority corresponding to the third cell. In some embodiments, if the terminal stops performing the AIOT operation, the terminal releases the highest priority of the frequency priority corresponding to the third cell;

[0323] In some embodiments, if the terminal determines that the third indication information is received, the third indication information is used to instruct the network side not to select the terminal as a reader for performing AIOT operations, and the terminal releases the highest priority of the frequency priority corresponding to the third cell.

[0324] Step S2104: The terminal performs cell selection or reselection based on the first information.

[0325] In some embodiments, a terminal obtains first information, where the first information is used to indicate the frequency priority of the cell in which the terminal can reside. The terminal performs cell selection or reselection based on the frequency priority. Exemplarily, the first information indicates that the cells in which the terminal can reside are A, B, and C, and the corresponding frequency priorities are L1, L2, and L3, respectively, where L1 has a higher level than L2, and L2 has a higher level than L3. If the terminal can select A, B, and C for residency when performing cell selection or reselection, the terminal will preferentially select the cell A with the highest level for residency.

[0326] It should be noted that the embodiment of the present disclosure may perform step S2104 without performing step S2103, that is, the terminal may perform cell selection or reselection without adjusting the frequency priority indicated by the first information, and step S2103 may be an optional step. Of course, step S2104 may also be performed on the premise of performing step S2106, which is not limited here.

[0327] In some embodiments, the terminal determines that it is in an RRC non-connected state, and the terminal performs cell selection or reselection based on the first information.

[0328] In some embodiments, the term "information" can be interchangeable with terms such as "message", "signal", "signaling", "report", "configuration", "indication", "instruction", "command", "channel", "parameter", "field", and "data".

[0474] Step S5101: The access network device sends first information to the terminal.

[0475] In some embodiments, the terminal receives first information sent by the access network device.

[0476] In some embodiments, the first information is used for the terminal to perform cell selection or reselection; the terminal is a terminal that supports and / or agrees to participate in the execution of AIOT operations of an environment Internet of Things device; the first information is used to indicate the frequency priority corresponding to the cell in which the terminal can reside.

[0477] The optional implementation of step S5101 can refer to the optional implementation of step S2101 in Figure 2a and other related parts of the embodiment involved in Figure 2a, which will not be repeated here.

[0478] In some embodiments, the above method may include the methods of the above-mentioned communication system side, terminal side, network device side, etc. embodiments, which will not be repeated here.

[0479] In order to better understand the embodiments of the present disclosure, the present disclosure is further described below through some exemplary embodiments:

[0480] Please refer to Figure 6a, which shows the communication connection between the access network equipment (BS), the terminal (UE) and the AIOT device (Ambient IoT device).

[0481] Example 1: The network side configures a frequency priority dedicated to AIOT operations (or terminals with ambient IOT operation capabilities) through system broadcast messages.

[0482] In some embodiments, the network cell configures a frequency priority configuration (corresponding to the first information) specifically for terminals supporting ambient IoT operations through system broadcast information.

[0483] In some embodiments, each frequency layer of the frequency priority configuration is associated with a priority configuration, and / or a sub-priority configuration associated with each frequency layer, and / or an indication of whether the per-frequency configuration supports ambient IoT operation. The configuration information (corresponding to the first information) may also include a timer configuration.

[0484] In some embodiments, the configuration effective time includes Option 1 and Option 2.

[0485] Option 1: Once a UE that supports ambient IOT operation and / or agrees to participate in ambient IOT operation receives the configuration (corresponding to the first information), it is considered that the configuration is effective, and the terminal uses the configuration to perform cell reselection and RRM measurement.

[0486] In some embodiments, once the configuration takes effect, a timer T1 is started. If the timer times out, the configuration is considered invalid, the UE locally releases the configuration, and adopts the public frequency priority configuration configured in the system broadcast information.

[0487] Option 2: A UE that supports ambient IOT operation and / or a UE that agrees to participate in ambient IOT operation, once receiving the configuration, saves the configuration. When receiving configuration activation indication information or configuration effectiveness indication information (corresponding to the third information) from the network side, the configuration is considered to be effective, and the terminal adopts the configuration for cell reselection and RRM measurement. The network-side configuration activation indication information or configuration effectiveness indication information can be configured through system broadcast information or indicated by paging DCI, or SI-RNTI scrambled DCI indication, or newly defined RNTI scrambled DCI.

[0488] In some embodiments, once the configuration takes effect, a timer T1 is started. If the timer times out, the configuration is considered invalid, the UE locally releases the configuration, and adopts the public frequency priority configuration configured in the system broadcast information.

[0489] In some embodiments, the configuration invalid time includes Option 1 to Option 5.

[0490] Option 1: If a timer is configured and the timer times out, the frequency priority configuration (first information) dedicated to ambient IoT is considered invalid.

[0491] Option 2: Based on network-side configuration deactivation indication information or configuration invalidation indication information, the configuration is considered invalid through such explicit indication (i.e., the network side sends the configuration deactivation indication information or configuration invalidation indication information), and the configuration is released (i.e., the first information is released). The network-side configuration deactivation indication information or configuration invalidation indication information can be configured through system broadcast information or indicated by paging DCI, SI-RNTI scrambled DCI, or newly defined RNTI scrambled DCI.

[0492] Option 3: If the cell is reselected to another cell, or the cell is reselected to a cell that does not support the ambient IOT operation, the configuration is considered invalid and released.

[0493] Option 4: If the configuration is valid based on the received configuration, the configuration can be invalidated based on the network side. For example, if the configuration is not configured in the system broadcast information, it is considered invalid. An indication is added through paging DCI to indicate the configuration change, reconfiguration, or deconfiguration of the ambient IoT dedicated frequency priority configuration.

[0494] Option 5: The network also configures a range of cells when configuring frequency priority. The range can be a list of cells. Within this range, the UE considers the acquired frequency priority valid. Outside this range, the UE considers it invalid and releases the configuration.

[0495] Example 2: The network side configures a dedicated frequency priority for ambient IoT operations (or terminals capable of ambient IoT operations) through dedicated signaling.

[0496] In some embodiments, for a terminal supporting ambient IOT entering the RRC_CONNECTED state, the network side obtains the UE's capability to support ambient IOT and / or the user consent of the UE's willingness to act as a reader. The network side will configure the dedicated frequency priority used by the UE after entering RRC_IDLE / INACTIVE in the RRC dedicated signaling, and may also configure a timer and / or a valid area range.

[0497] In some embodiments, the configuration effective time includes Option 1 and Option 2.

[0498] Option 1: A UE that supports ambient IoT operation and / or agrees to participate in ambient IoT operation, upon receiving the configuration and entering RRC_IDLE / INACTIVE, considers the configuration to be effective and uses the configuration for cell reselection and RRM measurement.

[0499] In some embodiments, once the configuration takes effect, a timer T1 is started. If the timer times out, the configuration is considered invalid, the UE locally releases the configuration, and adopts the public frequency priority configuration configured in the system broadcast information.

[0500] Option 2: A UE that supports ambient IoT operation and / or agrees to participate in ambient IoT operation, upon receiving the configuration, saves the configuration. Upon receiving configuration activation indication information or configuration validity indication information from the network side, the configuration is considered valid and the terminal uses the configuration for cell reselection and RRM measurement. The network-side configuration activation indication information or configuration validity indication information can be configured through system broadcast information or indicated by paging DCI, SI-RNTI scrambled DCI, or newly defined RNTI scrambled DCI.

[0501] In some embodiments, once the configuration takes effect, a timer T1 is started. If the timer times out, the configuration is considered invalid, the UE locally releases the configuration, and adopts the public frequency priority configuration configured in the system broadcast information.

[0502] In some embodiments, the configuration invalid time includes Option 1 to Option 5.

[0503] Option 1: If a timer is configured and the timer times out, the frequency priority configuration (first information) dedicated to ambient IoT is considered invalid.

[0504] Option 2: Based on network-side configuration deactivation indication information or configuration invalidation indication information, the configuration is considered invalid through such explicit indication (i.e., the network side sends the configuration deactivation indication information or configuration invalidation indication information), and the configuration is released (i.e., the first information is released). The network-side configuration deactivation indication information or configuration invalidation indication information can be configured through system broadcast information or indicated by paging DCI, SI-RNTI scrambled DCI, or newly defined RNTI scrambled DCI.

[0505] Option 3: If the cell is reselected to another cell, or the cell is reselected to a cell that does not support the ambient IOT operation, the configuration is considered invalid and released.

[0506] Option 4: If the configuration is valid based on the received configuration, the configuration can be invalidated based on the network side. For example, if the configuration is not configured in the system broadcast information, it is considered invalid. An indication is added through paging DCI to indicate the configuration change, reconfiguration, or deconfiguration of the ambient IoT dedicated frequency priority configuration.

[0507] Option 5: The network also configures a range of cells when configuring frequency priority. The range can be a list of cells. Within this range, the UE considers the acquired frequency priority valid. Outside this range, the UE considers it invalid and releases the configuration.

[0508] In some embodiments, if the frequency priority configured by dedicated signaling is effective, if the configuration exists in the system broadcast, the configuration in the system broadcast is ignored. If the dedicated configuration fails, the configuration in the system broadcast is used, and the description in Example 1 is referred to.

[0509] Example 3: Based on UE capabilities or network-side configuration information, ambient IoT automatically adjusts frequency priority.

[0510] In some embodiments, for terminals that support ambient IOT and / or UE is willing to act as a reader, that is, there is user consent, Option 1 to Option 3 can be executed.

[0511] Option 1: If the UE obtains the capability indication information indicating that the network supports ambient IoT operations from the network side, the UE considers that the frequency of the cell has the highest priority.

[0512] Option 2: If the UE obtains the configuration information to become a reader from the network side and enters the RRC_IDLE / INACTIVE state, the UE considers that the frequency priority of the current cell is the highest.

[0513] Option 3: If the UE receives an ambient IOT operation start indication from the network side, or a UE reader selection indication, the UE considers that the frequency of the cell has the highest priority.

[0514] In some embodiments, the terminal releases the highest priority, including Option 1 and Option 2.

[0515] Option 1: The timer configured on the network side times out and the highest priority is released. When the timer is started, it takes effect from the time when the highest priority is considered.

[0516] Option 2: Capability indication information or operation start indication is not configured, or the ambient IoT operation is explicitly indicated to stop, and the UE reader does not select the indication, etc., and the highest priority is released.

[0517] In the embodiments of the present disclosure, some or all of the steps and their optional implementations may be arbitrarily combined with some or all of the steps in other embodiments, or may be arbitrarily combined with the optional implementations of other embodiments.
