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.

[0088] 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".

[0089] 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.

[0090] In some embodiments, the first device is a terminal, the second device is a network device, and the fourth device is a charging node.

[0091] As shown in FIG1A , the method provided in the embodiment of the present disclosure may be applied to a wireless communication system 100, which may include a first network device 101, a second network device 102, a third network device 103, and a terminal 104. 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.

[0092] The wireless communication system 100 is applicable to both low-frequency 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, future evolved public land mobile networks (PLMN) systems, and Internet of Things systems.

[0093] The first network device 101 may be a node for receiving uplink information of a terminal.

[0094] The second network device 102 may be a device for sending an excitation signal to the first device. In one example, the second network device 102 is a continuous wave node (CWN), and the excitation signal is a continuous electromagnetic wave.

[0095] The third network device 103 may be a network node such as a base station.

[0096] Terminal 104 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, an Internet of Things terminal, etc. The terminal 104 may have wireless transceiver capabilities, and may communicate (e.g., wirelessly) with one or more network devices of one or more communication systems and receive network services provided by the network devices, where the network devices include but are not limited to the illustrated network device 102. Terminal 104 may also be an Internet of Things terminal. Compared to ordinary terminals, Internet of Things terminals have lower complexity, manufacturing costs, and maintenance costs. Internet of Things terminals may not be equipped with batteries and may be powered by receiving electromagnetic signals. Internet of Things terminals may also have a small amount of battery with electrical storage capabilities, which does not require manual charging but instead obtains battery energy from the outside, for example, by obtaining battery energy from external electromagnetic waves, thermal energy, kinetic energy, etc.

[0097] In some embodiments, different terminals 104 have different capabilities. For example, different terminals 104 may have different types and working modes, and their power acquisition and storage capabilities may also be different.

[0098] The capabilities of the first type of terminal (which may be referred to as device A) include: being unable to actively send uplink signals.

[0099] In some possible embodiments, the first type of terminal (which may be referred to as device A) may or may not have energy storage capability.

[0100] In some possible embodiments, the first type of terminal (which may be referred to as device A) can only passively send uplink signals.

[0101] For example, after receiving the excitation signal sent by the network device, the first type of terminal uses the backscattering working mode to send an uplink signal. If the first type of terminal does not receive the excitation signal sent by the network device, it cannot actively send an uplink signal.

[0102] The capabilities of the second type of terminal (which may be referred to as device B) include: having energy storage capability and being unable to actively send uplink signals.

[0103] The capabilities of the third type of terminal (which may be referred to as device C) include: energy storage capability and the ability to actively send uplink signals.

[0104] In one example, the third type of terminal has a radio frequency (RF) module that actively sends uplink signals.

[0105] Of the three types of terminals mentioned above, Type 3 terminals have the strongest capabilities and the highest cost. Type 1 terminals have the weakest capabilities and the lowest cost. Furthermore, since Type 1 and Type 2 terminals can only operate in backscatter mode and cannot actively transmit uplink signals, their supported coverage range is smaller. However, the power consumption of Type 1 and Type 2 terminals in their operating mode is lower than that of Type 3 terminals.

[0106] In some embodiments, the terminal 104 is an Ambient-IoT.

[0107] In some embodiments, AmbientIoT uses backscatter communications technology.

[0108] Backscatter communication utilizes the principle of RF signal backscattering to create an extremely low-power modulation and transmission technology. Since RF signals are partially reflected when they reach surfaces, the transmitting node adjusts the matching between the receiving antenna and the impedance based on the intended transmission information, enhancing the reflection of the incoming RF signal. The node then modulates the acquired sensory data onto the reflected signal, completing the data transmission.

[0109] During backscatter communication, a terminal receives a radio frequency signal. Its internal circuitry modulates the incoming electromagnetic wave to transmit the information, using methods such as load impedance modulation. The modulated electromagnetic wave carrying the information is then transmitted. Information can be modulated using a variety of methods, including amplitude shift keying (ASK), frequency shift keying (FSK), and phase shift keying (PSK).

[0110] For terminals using backscatter communication, the process is as follows: the network device sends a downlink command to the terminal. After receiving the downlink command, the terminal sends a corresponding response message to the network device or performs the corresponding operation. While sending the response message, the terminal needs the CWN to provide it with electromagnetic waves for reflection. The CWN can be a separate node, a base station, or an intermediate node (such as a UE) that communicates with the terminal. Continuous electromagnetic waves (CW) generally have a constant amplitude. The frequency of the electromagnetic wave reflected by the terminal can be exactly the same as the frequency of the continuous electromagnetic wave, or there can be some offset. The value of this offset depends on the hardware characteristics of the terminal. The offset can be a fixed value, one of multiple fixed values ​​if the terminal hardware supports it, or a dynamically adjustable value.

[0111] Compared with other communication technologies, backscatter communication has the following advantages: it does not require complex RF structures, 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, backscatter communication technology can simplify terminal design and significantly reduce terminal node costs.

[0112] In some embodiments, as shown in FIG1B , the IoT terminal may have four types of links. Specifically:

[0113] The first link is a downlink for receiving downlink data, which can be called link1;

[0114] The second link is the uplink for transmitting uplink data and can be called link2;

[0115] The third link is used to receive continuous electromagnetic waves and can be called link 3;

[0116] The fourth link is a link for receiving charging signals, which may be referred to as link 4.

[0117] The four nodes involved in these four links can be the same node, or two, three, or four separate nodes.

[0118] For example, the node connected by the first link is a downlink signal node (DSN), the node connected by the second link is an uplink receiver (UR), the node connected by the third link is a continuous electromagnetic wave node (CWN), and the node connected by the fourth link is an energy source node (ESN).

[0119] The fourth link (Link 4) can be controlled by the network. For example, network device 102 can control the ESN to enable or disable charging for the terminal. The energy in the fourth link (Link 4) can come from electromagnetic waves or non-electromagnetic charging signals. In this case, it can be considered that the ESN can better cooperate with network scheduling and other functions to ensure terminal charging while minimizing the impact on terminal communication.

[0120] The fourth link (Link 4) may also be uncontrolled by the network. In other words, the terminal can flexibly collect energy based on its capabilities and energy sources in the actual environment. For example, it can collect energy from electromagnetic waves or non-electromagnetic waves that are not controlled by the network. In this case, the fourth link (Link 4) can be considered non-existent.

[0121] The following embodiments of the present disclosure are applicable to terminals having energy storage capabilities, and may be applicable to a first type of terminal (which may be referred to as device A), a second type of terminal (which may be referred to as device B), or a third type of terminal (which may be referred to as device C).

[0122] [Corrected 30.01.2024 in accordance with Rule 91] The present disclosure provides a method for adjusting power. FIG2 is a flow chart of a method for adjusting power according to an embodiment of the present disclosure. As shown in FIG2 , the method includes the following steps:

[0123] Step S2101 : The terminal 104 sends uplink information to the first network device 101 .

[0124] In some embodiments, the first network device 101 is an uplink receiver (UR).

[0125] In some embodiments, the terminal 104 sends uplink information to the first network device 101 through a channel.

[0126] In some embodiments, the terminal 104 sends uplink information to the first network device 101 through multiple channels.

[0127] Step S2102: The first network device 101 determines auxiliary information.

[0128] In some embodiments, the first network device 101 determines the auxiliary information according to the uplink information.

[0129] In some embodiments, the auxiliary information is used by the second network device 102 to adjust a first transmission power, where the first transmission power is a transmission power used by the second network device 102 to transmit a wireless signal to the terminal 104 .

[0130] In some embodiments, the second network device 102 is a CWN.

[0131] In some embodiments, when the terminal 104 sends uplink information to the first network device 101 through a channel, the first network device 101 determines the auxiliary information according to a first receiving power, where the first receiving power is the receiving power of the uplink information received through the one channel.

[0132] In some embodiments, when the terminal 104 sends all uplink information to the first network device 101 through one channel, the first network device 101 determines the auxiliary information based on a first receiving power, where the first receiving power is the receiving power of receiving all the uplink information through the one channel.

[0133] In some embodiments, the auxiliary information includes an adjustment reference value, where the adjustment reference value is determined according to the first received power and the reference received power.

[0134] In an example, the reference received power includes a received power corresponding to the sensitivity of the first network device 101 in receiving uplink information.

[0135] In one example, the adjustment reference value is a difference between the first received power and a reference received power.

[0136] In one example, the adjustment reference value is a ratio of the first received power to a reference received power.

[0137] In one example, the adjustment reference value is a correlation value between the first received power and the reference received power, and the correlation value is calculated according to a preset correlation algorithm.

[0138] In some embodiments, the auxiliary information is one of:

[0139] Adjust reference values;

[0140] a first received power;

[0141] The first network device 101 expects a power adjustment amount to be performed by the terminal.

[0142] In some embodiments, the auxiliary information is one of:

[0143] a difference between the first received power and the reference received power;

[0144] a first received power;

[0145] The first network device 101 expects a power adjustment amount to be performed by the terminal.

[0146] In some embodiments, when the terminal 104 sends uplink information to the first network device 101 through more than one channel, the first network device 101 determines the auxiliary information based on more than one second receiving power, where the second receiving power is the receiving power of receiving the uplink information on one channel.

[0147] In one example, when the terminal 104 sends uplink information to the first network device 101 through N channels, it corresponds to N second receiving powers, each second receiving power corresponds to one channel, and N is an integer greater than 1.

[0148] In some embodiments, the assistance information includes one of the following:

[0149] a difference between the second received power and a reference received power, wherein the reference received power includes a received power corresponding to the sensitivity of the first network device in receiving the uplink information;

[0150] a second received power;

[0151] The first network device 101 expects the power adjustment amount performed by the terminal 104 on a channel.

[0152] Step S2103 : The first network device 101 sends auxiliary information to the second network device 102 .

[0153] In some embodiments, when the first network device 101 knows that the terminal 104 corresponds to the second network device 102 , the first network device 101 directly sends the auxiliary information to the second network device 102 .

[0154] In some embodiments, when the first network device 101 is unaware of the second network device 102 corresponding to the terminal 104 , the first network device 101 sends auxiliary information to the third network device 103 , and the third network device 103 forwards the auxiliary information to the second network device 102 .

[0155] Step S2104: The second network device 102 adjusts the first transmission power.

[0156] In some embodiments, when the auxiliary information includes a difference between the second received power and the reference received power, adjusting the first transmit power according to the auxiliary information includes at least one of the following:

[0157] When the difference is greater than or equal to a first threshold, reducing the first transmit power;

[0158] When the difference is greater than or equal to a second threshold and less than or equal to a first threshold, the first transmit power is not adjusted; and the first threshold is greater than or equal to the second threshold;

[0159] When the difference is less than or equal to a second threshold, the first transmit power is increased.

[0160] In one example, on the uplink channel 1, the receiving power of the terminal 101 has a larger power margin compared to the UR receiving sensitivity, and on the uplink channel 2, the receiving power of the terminal 101 has a power margin of 0 or very little compared to the UR receiving sensitivity, and the terminal 101 is instructed to transmit on the uplink channel 2, then the second network device 102 will increase the transmission power to ensure that the terminal 101 can successfully transmit on the uplink channel 2.

[0161] In some embodiments, the auxiliary information includes a first receiving power, the power loss of the first transmission path is evaluated based on the first receiving power, and the adjusted first transmitting power is determined based on the power loss, wherein the first transmission path includes a path from the second network device 102 to the terminal 104 and a path from the terminal 104 to the first network device 101; the first transmitting power is adjusted according to the power adjustment amount.

[0162] In some embodiments, the path from the terminal 104 to the first network device 101 is a path from the terminal 104 to the first network device 101 on one channel.

[0163] In one example, the power loss of the path from second network device 102 to terminal 104 and from terminal 104 to first network device 101 via uplink channel 1 is evaluated based on the received power on uplink channel 1. Second network device 102 can evaluate the power loss of the path from second network device 102 to terminal 104 and from terminal 104 to first network device 101 via uplink channel 2 based on the received power of first network device 101 on uplink channel 2. For a path with greater power loss, second network device 102 transmits at a greater transmit power; for a path with less power loss, second network device 102 transmits at a smaller transmit power.
