[0113] The embodiments of the present disclosure are now further described with reference to the accompanying drawings and specific implementation methods.

[0114] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all possible implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

[0115] The terms used in the embodiments of the present disclosure are for the purpose of describing specific embodiments only and are not intended to limit the embodiments of the present disclosure. The singular forms "a," "an," and "the" used in the embodiments of the present disclosure and the appended claims are also intended to include plural forms unless the context clearly indicates otherwise. It should also be understood that the term "and / or" as used herein refers to and includes any or all possible combinations of one or more associated listed items.

[0116] It should be understood that although the terms first, second, third, etc. may be used to describe various information in the embodiments of the present disclosure, such information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of the embodiments of the present disclosure, the first indication information may also be referred to as the second indication information, and similarly, the second indication information may also be referred to as the first indication information. Depending on the context, the words "if" and "if" as used herein may be interpreted as "at the time of" or "when" or "in response to determining".

[0117] The embodiments of the present disclosure are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present disclosure, and should not be understood as limiting the present disclosure.

[0118] As shown in Figure 1, the method provided in the embodiment of the present disclosure can be applied to a wireless communication system 100, which may include a terminal 101, a first network device 102, and a second network device 103. It should be noted that the wireless communication system 100 may also include other devices, and this application does not limit the devices included in the wireless communication system 100.

[0119] It should be understood that the above wireless communication system 100 is applicable to both low-frequency scenarios and high-frequency scenarios. Application scenarios of the wireless communication system 100 include, but are not limited to, long-term evolution (LTE) systems, LTE frequency division duplex (FDD) systems, LTE time division duplex (TDD) systems, worldwide interoperability for microwave access (WiMAX) communication systems, cloud radio access networks (CRAN) systems, future fifth-generation (5G) systems, new radio (NR) communication systems, or future evolved public land mobile networks (PLMN) systems.

[0120] The terminal 101 shown above may be a terminal, an access terminal, a terminal unit, a terminal station, a mobile station (MS), a remote station, a remote terminal, a mobile terminal, a wireless communication device, a terminal agent, etc. The terminal 101 may have wireless transceiver capabilities, and may be capable of communicating (e.g., wirelessly communicating) with one or more network devices of one or more communication systems and receiving network services provided by the network devices, where the network devices include but are not limited to the illustrated network device 102.

[0121] Among them, the terminal 101 can be a cellular phone, a cordless phone, a session initiation protocol (SIP) phone, a wireless local loop (WLL) station, a personal digital assistant (PDA) device, a handheld device with wireless communication function, a computing device or other processing device connected to a wireless modem, an in-vehicle device, a wearable device, a terminal in a future 5G network, or a terminal in a future evolved PLMN network, etc.

[0122] For example, the first network device 102 or the second network device 103 may be an access network device (or access network point). An access network device refers to a device that provides network access functionality, such as a radio access network (RAN) base station. Specifically, it may include a base station (BS), or a base station and a radio resource management device for controlling the base station. It may also include relay stations (relay devices), access points, and base stations in future 5G networks, base stations in future evolved PLMN networks, or NR base stations. It may be a wearable device or an in-vehicle device. The network device 102 may also be a communication chip with a communication module.

[0123] For example, the first network device 102 or the second network device 103 includes but is not limited to: a next-generation base station (gnodeB, gNB) in 5G, an evolved node B (eNB) in an LTE system, a radio network controller (RNC), a node B (NB) in a WCDMA system, a wireless controller under a CRAN system, a base station controller (BSC), a base transceiver station (BTS) in a GSM system or a CDMA system, a home base station (for example, home evolved nodeB, or home nodeB, HNB), a baseband unit (BBU), a transmission point (TRP), a transmitting point (TP) or a mobile switching center, etc.

[0124] In the disclosed embodiments, IoT terminals have lower complexity, manufacturing costs, and maintenance costs than conventional terminals. IoT terminals can be battery-free and powered by receiving electromagnetic signals. IoT terminals can also include a small amount of battery storage that does not require manual charging but instead obtains energy from external sources, such as electromagnetic waves, heat, kinetic energy, and so on.

[0125] In the implementation of the present disclosure, different terminals have different capabilities. For example, different terminals have different types and working modes, and their power acquisition and storage capabilities may also be different.

[0126] The capabilities of the first type of terminal include: no energy storage capability, and no independent signal generation or amplification.

[0127] In one example, the first terminal uses a backscattering working mode.

[0128] The capabilities of the second type of terminal include: energy storage capability, and inability to generate independent signals.

[0129] In one example, the second terminal may use a backscattering working mode, and may also use the stored energy to amplify the reflected signal.

[0130] The capabilities of the third type of terminal include: energy storage capability and the ability to independently generate signals.

[0131] In one example, the third type of terminal has a radio frequency (RF) module that actively sends signals.

[0132] Of the three types of terminals mentioned above, the third type offers the strongest capabilities but the highest cost. The first type offers the weakest capabilities but the lowest cost. Furthermore, since the first and second types of terminals can only operate in backscatter mode and cannot actively transmit signals, their supported coverage range is smaller. However, their operating modes consume less power than the third type.

[0133] In the embodiments of the present disclosure, a terminal with strong capabilities can support multiple operating modes. It is necessary to consider how to determine the operating mode of the terminal.

[0134] FIG2A is an interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG2A , the embodiment of the present disclosure relates to a communication method, and the method includes:

[0135] Step S2101: The second network device 103 obtains first information.

[0136] In some embodiments, the first information is used to indicate at least one operating mode supported by the terminal, and the at least one operating mode includes at least one of the following:

[0137] Supports active signal transmission but not passive signal transmission;

[0138] Supports passive signal transmission but does not support active signal transmission;

[0139] Supports both active and passive signaling modes.

[0140] In some embodiments, the terminal supports three operating modes, which are:

[0141] Working mode A: supports active signal transmission but does not support passive signal transmission;

[0142] Working mode B: supports passive signal transmission but does not support active signal transmission;

[0143] Working mode C: a working mode that supports both active and passive signal transmission.

[0144] In one example, the passively transmitted signal is a backscattered transmitted signal.

[0145] In one example, the power consumption of passively transmitting a signal is lower than the power consumption of actively transmitting a signal.

[0146] In some embodiments, the second network device 103 obtains the first information when the terminal 101 signs a contract with an operator.

[0147] In some embodiments, the second network device 103 obtains the first information when the terminal 101 registers with the network.

[0148] In step S2102 , the second network device 103 sends first information to the first network device 102 .

[0149] In some embodiments, the first network device 102 receives the first information.

[0150] The first information in step S2102 can refer to the first information in step S2101, and will not be repeated here.

[0151] Step S2103 : The second network device 103 sends second information to the first network device 102 .

[0152] In some embodiments, the first network device 102 receives the second information.

[0153] In some embodiments, the second information is used to indicate a first operating mode, where the first operating mode is a default operating mode of the terminal 101, and the default operating mode is one of the at least one operating mode.

[0154] Step S2104 : The first network device 102 sends second information to the terminal 101 .

[0155] In some embodiments, terminal 101 receives second information.

[0156] The second information in step S2104 can refer to the second information in step S2103, and will not be repeated here.

[0157] Step S2105 : The first network device 102 sends fourth information to the terminal 101 .

[0158] In some embodiments, the fourth information is used to indicate a second operating mode, the second operating mode is an operating mode to be used by the terminal, and the second operating mode is one of the at least one operating mode.

[0159] In one example, when the distance between the first network device 102 and the terminal 101 is less than or equal to a threshold, or when the channel quality between the first network device 102 and the terminal 101 is better than or equal to a threshold value, the fourth information is used to indicate that the working mode is working mode B, that is, a working mode that supports passive signal transmission and does not support active signal transmission.

[0160] In another example, when the distance between the first network device 102 and the terminal 101 is greater than or equal to a threshold, or when the channel quality between the first network device 102 and the terminal 101 is worse than a threshold, the fourth information is used to indicate that the working mode is working mode A, that is, a working mode that supports active signal sending mode and does not support passive signal sending mode.

[0161] In some embodiments, the at least one second operating mode does not include the first operating mode.

[0162] In some embodiments, the second operating mode is different from the first operating mode.

[0163] In one example, the distance between the terminal 101 and the first network device 102 is greater than a threshold, the terminal 101 uses working mode A, and working mode A is the default working mode. The terminal 101 gradually approaches the first network device 102. When the distance between the first network device 102 and the terminal 101 is less than a threshold, the first network device 101 sends fourth information to the terminal 101 indicating that the second working mode is working mode B.

[0164] In another example, the distance between the terminal 101 and the first network device 102 is less than a threshold, the terminal 101 uses working mode B, and working mode B is the default working mode. The terminal 101 gradually moves away from the first network device 102. When the distance between the first network device 102 and the terminal 101 is greater than the threshold, the first network device 101 sends fourth information to the terminal 101 indicating that the second working mode is working mode A.

[0165] In some embodiments, the first network device 102 sends the fourth information to the terminal at a first moment, and the second working mode takes effect at a second moment, and the second moment is after the first moment.

[0166] In some embodiments, the interval between the first time and the second time is agreed upon by a protocol.

[0167] In some embodiments, the interval between the first time and the second time is configured by the first network device 102 .

[0168] In some embodiments, the number of the at least one operating mode is greater than one.

[0169] Step S2106 : The first network device 102 sends fifth information to the terminal 101 .

[0170] In some embodiments, the fifth information is used to indicate a duration of operation of the terminal in at least one second operating mode. When the operating duration ends, the terminal will fall back to the default operating mode.

[0171] In some embodiments, the second network device 103 is a core network device, and the first network device 102 is a base station.

[0172] The communication method involved in the embodiment of the present disclosure may include at least one of steps S2101 to S2106. For example, step S2102, step S2104, and step S2105 may be implemented as independent embodiments, but are not limited thereto.

[0282] An embodiment of the present disclosure relates to a communication method, which includes: a first network device obtains one or more working modes supported by a terminal.

[0283] In some embodiments, the operating mode may be one of the following:

[0284] Support active signal sending;

[0285] Support passive signal sending;

[0286] Supports active signaling and passive signaling.

[0287] In some embodiments, the terminal actively reports one or more working modes supported by the terminal to the first network device, or the base station obtains one or more working modes supported by the terminal through the core network.

[0288] In one example, when the terminal signs a contract with an operator or registers with a network, the second network device obtains one or more operating modes supported by the terminal, and the first network device notifies the first network device of the one or more operating modes supported by the terminal.

[0289] In some embodiments, upon learning that the terminal supports multiple operating modes, the base station may configure the operating mode of the terminal through signaling. For example, the first network device configures the terminal to use an active signaling operating mode, or the first network device configures the terminal to use a passive signaling operating mode.

[0290] In one example, when the terminal is close to the first network device, the passive signal transmission mode can also support the coverage requirement. Therefore, in this case, the first network device can configure the terminal to use the passive signal transmission working mode.

[0291] In some embodiments, the first network device may also obtain the default operating mode of the terminal. For example, the first network device may obtain the default operating mode of the terminal from the second network device. For example, the default operating mode of the terminal is the active signal transmission operating mode.

[0292] In some embodiments, the first network device may further configure the operating time of the terminal in a specified operating mode, and may fall back to the default operating mode of the terminal after a timeout.

[0293] For example, the first network device may configure the terminal to work in the passive signal transmission mode for 3 hours. After the 3 hours have expired, the terminal automatically falls back to the default working mode, ie, the active signal transmission working mode.

[0294] In some embodiments, the terminal may indicate to the first network device the operating mode to be used by the terminal.

[0295] For example, the terminal sends the operating mode to be used by the terminal to the base station at time T1, and the operating mode will take effect at time T2, which is after T1.

[0296] The embodiments of the present disclosure further provide an apparatus for implementing any of the above methods. For example, an apparatus is provided, comprising units or modules for implementing each step performed by a terminal in any of the above methods. For another example, another apparatus is provided, comprising units or modules for implementing each step performed by a network device (e.g., an access network device, a core network function node, a core network device, etc.) in any of the above methods.

[0297] It should be understood that the division of the various units or modules in the above device is merely a division of logical functions. In actual implementation, they may be fully or partially integrated into a physical entity, or they may be physically separated.

Alternatively, the units or modules in the device can be implemented in the form of hardware circuits, and the functions of some or all of the units or modules can be realized by designing the hardware circuits. The above-mentioned hardware circuits can be understood as one or more processors; for example, in one implementation, the above-mentioned hardware circuit is an application-specific integrated circuit (ASIC), which realizes the functions of some or all of the above units or modules by designing the logical relationship of the components in the circuit; for example, in another implementation, the above-mentioned hardware circuit can be realized by a programmable logic device (PLD). Taking a field programmable gate array (FPGA) as an example, it can include a large number of logic gate circuits, and the connection relationship between the logic gate circuits is configured by configuring the configuration file, thereby realizing the functions of some or all of the above units or modules. All units or modules of the above devices can be realized in the form of software called by the processor, or in the form of hardware circuits, or in part by the form of software called by the processor, and the rest by hardware circuits.

[0298] In the embodiments of the present disclosure, the processor is a circuit with signal processing capabilities. In one implementation, the processor can be a circuit with instruction reading and execution capabilities, such as a central processing unit (CPU), a microprocessor, a graphics processing unit (GPU) (which can be understood as a microprocessor), or a digital signal processor (DSP).

The logical relationship of the above-mentioned hardware circuit is fixed or reconfigurable. For example, the processor is a hardware circuit implemented by an application-specific integrated circuit (ASIC) or a programmable logic device (PLD), such as an FPGA. In a reconfigurable hardware circuit, the process of the processor loading a configuration document and implementing the hardware circuit configuration can be understood as the process of the processor loading instructions to implement the functions of some or all of the above units or modules. In addition, it can also be a hardware circuit designed for artificial intelligence, which can be understood as an ASIC, such as a neural network processing unit (NPU), a tensor processing unit (TPU), a deep learning processing unit (DPU), etc.
