For example, ambient energy can be wireless radio frequency signals, solar energy, thermal energy, mechanical energy, etc.

[0003] When AMP terminals are introduced into current communication networks, since the energy of the AMP terminals comes from the environment and the AMP terminals have limited energy storage capacity, the AMP terminals cannot well support the transmission mechanism in the current communication networks, resulting in failure of data transmission and reception.

Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0039] FIG1 is a schematic diagram of a communication system architecture according to an embodiment of the present application.

[0040] As shown in Figure 1, a communication system 100 may include a terminal device 110 and a network device 120. The network device 120 may communicate with the terminal device 110 via an air interface. The terminal device 110 and the network device 120 support multi-service transmission.

[0041] It should be understood that the embodiments of the present application are only illustrative of the communication system 100, but the embodiments of the present application are not limited thereto. That is, the technical solutions of the embodiments of the present application can be applied to various communication systems, such as: Long Term Evolution (LTE) system, LTE Time Division Duplex (TDD), Universal Mobile Telecommunication System (UMTS), Internet of Things (IoT) system, Narrow Band Internet of Things (NB-IoT) system, enhanced Machine-Type Communications (eMTC) system, 5G communication system (also known as New Radio (NR) communication system), or future communication systems.

[0042] In the communication system 100 shown in Figure 1, the network device 120 may be an access network device that communicates with the terminal device 110. The access network device may provide communication coverage for a specific geographical area and may communicate with the terminal device 110 (eg, UE) located within the coverage area.

[0044] The terminal device 110 may be any terminal device, including but not limited to a terminal device connected to the network device 120 or other terminal devices by wire or wireless connection.

[0045] For example, the terminal device 110 may refer to an access terminal, user equipment (UE), a subscriber unit, a subscriber station, a mobile station, a mobile station, a remote station, a remote terminal, a mobile device, a user terminal, a terminal, a wireless communication device, a user agent, or a user apparatus.

Of course, the methods described in the embodiments of this application can also be applied to other systems. Furthermore, the terms "system" and "network" are often used interchangeably herein. The term "and / or" herein simply describes an association relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / " generally indicates that the associated objects are in an "or" relationship. It should also be understood that the "indication" mentioned in the embodiments of this application can be a direct indication, an indirect indication, or an indication of an association relationship. For example, "A indicates B" can mean that A directly indicates B, for example, B can obtain information through A; it can also mean that A indirectly indicates B, for example, A indicates C, and B can obtain information through C; or it can mean that A and B have an association relationship. It should also be understood that the "correspondence" mentioned in the embodiments of this application can mean that there is a direct or indirect correspondence between two objects, or that there is an association relationship between the two objects, or a relationship between an indicator and the indicated, a configuration and the configured, and so on. It should also be understood that the “predefined” or “predefined rules” mentioned in the embodiments of the present application can be implemented by pre-saving corresponding codes, tables or other methods that can be used to indicate relevant information in devices (for example, including terminal devices and network devices), and the present application does not limit its specific implementation method. For example, predefined can refer to what is defined in the protocol. It should also be understood that in the embodiments of the present application, the “protocol” may refer to a standard protocol in the field of communications, such as LTE protocols, NR protocols, and related protocols used in future communication systems, and the present application does not limit this.

[0052] To facilitate understanding of the technical solutions of the embodiments of the present application, the relevant technologies of the embodiments of the present application are described below. The following relevant technologies can be arbitrarily combined with the technical solutions of the embodiments of the present application as optional solutions, and they all fall within the protection scope of the embodiments of the present application.

[0053] The development of communication technology will place higher requirements on the price and power consumption of terminal equipment. In particular, low-complexity, low-cost, low-power zero-power terminals will become the mainstream equipment in future communication networks.

[0054] Based on the energy source and usage of zero-power terminals, zero-power terminals can be divided into the following types:

[0055] 1. Passive zero-power terminal

[0056] A passive zero-power terminal does not require a built-in battery. When it approaches a network device (such as an RFID reader), it is within the near-field radiation generated by the network device's antenna. At this point, the passive zero-power terminal's antenna generates an induced current through electromagnetic induction. This induced current drives the low-power chip circuit of the zero-power terminal to operate, achieving operations such as demodulation of forward link signals and modulation of backward link signals. For backscatter links, the zero-power terminal uses backscattering to transmit signals.

[0057] It can be seen that the passive zero-power terminal does not require a built-in battery to drive either the forward link or the reverse link, and is a true zero-power terminal.

[0058] Passive zero-power terminals do not require batteries, and their RF circuits and baseband circuits are very simple. For example, they do not require low-noise amplifiers (LNAs), power amplifiers (PAs), crystal oscillators, analog-to-digital converters (ADCs), and other devices. Therefore, they have many advantages such as small size, light weight, very low price, and long service life.

[0059] 2. Semi-passive zero-power terminal

[0060] Semi-passive zero-power terminals do not have conventional batteries themselves, but instead use radio frequency (RF) energy harvesting modules to harvest radio wave energy and store the harvested energy in an energy storage unit (such as a capacitor). This energy storage unit then drives the low-power chip circuitry of the zero-power terminal, performing tasks such as demodulating forward link signals and modulating backward link signals. For backscatter links, the zero-power terminal uses backscattering to transmit signals.

[0061] It can be seen that the semi-passive zero-power terminal does not require a built-in battery to drive either the forward link or the reverse link. Although energy stored in capacitors is used in operation, the energy comes from the radio energy collected by the energy harvesting module. Therefore, it is also a true zero-power terminal.

[0062] Semi-passive zero-power consumption terminals inherit many advantages of passive zero-power consumption terminals, so they have many advantages such as small size, light weight, very low price, and long service life.

[0063] 3. Active zero-power terminal

[0064] Active zero-power terminals can be powered by built-in batteries, which drive the terminal's low-power chip circuits to perform tasks such as demodulating forward link signals and modulating reverse link signals. However, for backscatter links, zero-power terminals use backscattering to transmit signals. Therefore, the zero-power nature of these terminals lies primarily in the fact that reverse link signal transmission does not require the terminal's own power, but rather utilizes backscattering.

[0065] Active zero-power terminals can increase their communication distance and improve communication reliability. Therefore, they are used in scenarios with relatively high requirements for communication distance and read latency.

[0066] Currently, the 3rd Generation Partnership Project (3GPP) is studying how to support ambient energy-based devices in NR systems and WiFi systems. Ambient energy-based devices can be called Ambient IoT, AMP IoT devices, AMP terminals, etc. The energy required for their operation comes from ambient energy collection, which can be from wireless radio frequency signals, solar energy, thermal energy, mechanical energy, etc. This type of device is similar to passive or semi-passive devices in zero-power communications. AMP IoT devices collect ambient energy and store it in energy storage units. After the energy storage unit obtains sufficient energy, it can drive low-power circuits to operate for forward link signal demodulation and reverse link signal modulation and transmission operations.

[0067] Ambient IoT devices are broadly classified into three types: Device A, Device B, and Device C. Each type of device possesses corresponding levels of complexity and communication capabilities. Device A lacks energy storage capabilities and cannot transmit independent signals, employing backscatter transmission. Device B, while capable of energy storage, cannot transmit independent signals and employs backscatter transmission, utilizing stored energy to amplify the backscattered signal. Device C, however, possesses energy storage capabilities and can transmit independent signals, demonstrating active transmission capabilities.

[0068] It should be noted that Device A has the lowest complexity and power consumption, reaching as low as 1μW. However, its communication range is limited, typically only a few meters. Device A requires a network device to provide a carrier signal for backscattering transmission. Device C typically has a large capacitor to store energy from the environment, consumes several hundred μW, and can support active signal transmission, thus having a longer communication range. Because Device C can perform active transmission, it does not require a network device to provide a carrier signal. Device B's complexity and power consumption are between Device A and Device C.

[0069] The following introduces the Discontinuous Reception (DRX) technology.

[0070] In practical applications, LTE and NR systems can use the DRX mechanism to save power for terminal devices. The principle of the DRX mechanism is that when there is no data to be received, the terminal device does not need to keep the receiver turned on, but enters a discontinuous reception state, thereby achieving the purpose of saving power. Referring to the schematic diagram of the principle of a DRX mechanism shown in Figure 2, the DRX mechanism includes configuring a DRX cycle (DRX cycle) for a terminal device in the RRC_CONNECTED state. A DRX cycle can be composed of a duration (On Duration) and a sleep period (Opportunity for DRX). During the "On Duration" period, the terminal device can monitor and receive downlink channels and signals including PDCCH; during the "Opportunity for DRX" period, the terminal device may not receive downlink channels and signals such as PDCCH to reduce power consumption.

[0071] In some embodiments, the terminal device's DRX cycle can be configured as either a short or long cycle. When in a short DRX cycle, the terminal device starts and restarts a timer based on the reception of scheduled data. When the timer expires, the terminal device switches to a long DRX cycle to further save power. The network can also initiate a short or long DRX cycle via a DRX command, which is sent to the UE via a MAC CE.

[0072] Refer to Figure 3 for a timing diagram of DRX cycle switching. Assume that the terminal device is configured with short-cycle DRX and long-cycle DRX. The terminal device is initially in long-cycle DRX, and when it receives data scheduling, it starts or restarts the drx-InactivityTimer timer. When the drx-InactivityTimer timer times out or the terminal device receives a DRX command (DRX Command), the terminal device can enter short-cycle DRX and start the drxShortCycleTimer timer at the same time. When the timer times out or the terminal device receives a long-cycle DRX command (Long DRX Command), the terminal device enters long-cycle DRX. Among them, before the timer drx-InactivityTimer times out, the terminal device needs to always detect the physical downlink control channel (Physical Downlink Control Channel, PDCCH). Before the timer drxShortCycleTimer times out, the terminal device also needs to always perform discontinuous reception according to short-cycle DRX.

[0073] Discontinuous Transmission (DTX), similar to DRX, is also designed to save power. In DTX, a terminal device alternates between a continuous and a sleep period. During the sleep period, the terminal device turns off the transmitter until the continuous period begins, when it turns on again, repeating this cycle.

[0074] It should be understood that the purpose of the DRX / DTX mechanism is to save energy and power for terminal devices. Among them, the duration and dormancy period in the DRX / DTX mechanism are mainly determined by the activity of data transmission of the terminal device. For traditional terminal devices, which are mainly powered by batteries, their behavior of receiving or sending data does not need to consider the limitations of the energy storage status of the terminal device. When the current communication network, especially the cellular network, supports AMP terminal access, since the energy of the AMP terminal comes from the environment and the AMP terminal has limited energy storage capacity, the AMP terminal will not be able to support the existing DRX / DTX mechanism well, resulting in failure of data reception and transmission.

[0075] Based on this, embodiments of the present application provide a method for determining a transmission state, wherein a terminal device can determine its transmission state. The transmission states include multiple types, and different transmission states are related to the energy storage state of the terminal device. In other words, the terminal device can determine the transmission state based on the energy storage state. In this way, the terminal device can reasonably utilize the energy storage state for transmission, thereby increasing the success rate of data transmission.

[0076] To facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions of the present application are described in detail below through specific embodiments. The above related technologies can be combined arbitrarily with the technical solutions of the embodiments of the present application as optional solutions, and all of them fall within the scope of protection of the embodiments of the present application. The embodiments of the present application include at least part of the following contents.

[0077] FIG4 shows a method for determining a transmission status provided by an embodiment of the present application. The method may include:

[0078] S410. The terminal device determines a transmission state; wherein the transmission state includes multiple transmission states, and different transmission states are related to the energy storage state of the terminal device.

[0079] It should be noted that the transmission status can be understood as the transmission status or communication status of data between the terminal device and the network device, and can be used to describe whether data is transmitted between the terminal device and the network device, when data is transmitted, the duration of each data transmission, and other states.

[0080] It should also be noted that the transmission state may include a receiving state and / or a sending state.

[0081] The receiving status may be used to describe whether the terminal device is receiving data, when the data is received, the duration of each data reception, and other statuses.

[0082] Exemplarily, the receiving state may be a DRX state, and the terminal device may monitor the downlink channel or signal during the "On Duration" period and not receive data during the sleep period.

[0083] In addition, the sending status can be used to describe whether the terminal device sends data, when the data is sent, the duration of each data transmission, and other states.

[0084] Exemplarily, the transmission state may be a DTX state, where the terminal device turns on the transmitter during the "On Duration" period to transmit data, and turns off the transmitter during the sleep period to not transmit data.

[0085] It should be noted that the terminal device may have multiple transmission states, and in different transmission states, the terminal device may have different behaviors / operations for data transmission.

[0086] In some embodiments, the transmission state may be determined based on one or more of the following parameters, or in other words, the transmission state may be defined based on one or more of the following parameters:

[0087] whether data transmission is performed;

[0088] Discontinuous transmission cycle;

[0089] The duration of continuous transmission within a discontinuous transmission period.

[0090] That is, the transmission status of the terminal device can be described according to one or more of whether data transmission is performed, a discontinuous transmission period, and a duration of continuous transmission within the discontinuous transmission period.

[0091] In one possible implementation, the transmission state of the terminal device may be a continuous transmission state, in which the terminal device performs continuous data transmission. That is, as long as the terminal device switches to this transmission state, it needs to continue to perform data transmission until exiting the transmission state.

[0092] In another possible implementation, the transmission state of the terminal device may be a non-transmission state, in which the terminal device does not transmit data. That is, once entering the transmission state, the terminal device needs to stop any data transmission.

[0093] In another possible implementation, the transmission state of the terminal device may be a discontinuous transmission state, in which the terminal device performs discontinuous transmission. That is, after the terminal device enters the transmission state, it may perform data transmission for part of the time and not perform data transmission for the rest of the time.

[0094] It should be noted that the discontinuous transmission state can be configured by the discontinuous transmission cycle and the continuous transmission duration. The discontinuous transmission cycle can be understood as the DRX cycle and / or DTX cycle, and the continuous transmission duration can be understood as the "On Duration" length within the DRX cycle and / or DTX cycle.

[0095] In some embodiments, the duration of data transmission in different transmission states may be different.

[0096] For example, in one transmission state, the terminal device performs any data transmission, and in another transmission state, the terminal device continuously performs data transmission. Alternatively, the terminal device performs discontinuous transmission, and in one transmission state, the total duration of the terminal device's discontinuous transmission is a first duration, and in another transmission state, the total duration of the terminal device's discontinuous transmission is a second duration, and the first duration and the second duration are different.

[0097] In some embodiments, different transmission states can be determined based on different parameters. That is, in different transmission states, one or more of whether data transmission is performed, the discontinuous transmission period, and the duration of continuous transmission within the discontinuous transmission period can vary. For example, the transmission states can include a first discontinuous transmission state and a second discontinuous transmission state, wherein the discontinuous transmission period and / or the duration of continuous transmission in the first discontinuous transmission state and the second discontinuous transmission state can differ.

[0098] It should be noted that the various transmission states of a terminal device may be predefined or configured by the network device. For example, the network device may configure / update the various transmission states for the terminal device via high-layer signaling or physical layer signaling. Specifically, the network device may configure the aforementioned parameters corresponding to each transmission state for the terminal device.

[0099] The terminal device in the embodiments of the present application can be a zero-power terminal. For example, the terminal device can be an AMP terminal. Taking RF energy harvesting as an example, the AMP terminal collects radio waves through an RF energy harvesting module, thereby obtaining radio energy and storing it in an energy storage unit. After the energy storage unit obtains sufficient energy, it can drive the low-power circuit to operate for operations such as forward link signal demodulation and reverse link signal modulation and transmission.

[0100] For AMP terminals that harvest energy through wireless RF signals, the energy received by their receivers can generally only be used for information demodulation or energy harvesting. That is, before receiving a wireless RF signal, the AMP terminal must decide whether to process the RF signal for information demodulation or energy harvesting. If the current energy storage level allows, the AMP terminal can use stored energy for information demodulation without energy harvesting. In other words, the AMP terminal's processing of the RF signal depends on whether it is currently in energy harvesting or transmission (or communication) mode. These two modes are often temporally separate, meaning they occur at different times. This is partly because the communication signal and the RF signal used for energy harvesting may not be in the same frequency band. Even if they are in the same frequency band, energy harvesting and communication can proceed simultaneously, requiring the received signal power to be split, with one portion used for information demodulation and the other for energy harvesting. However, these approaches require high receiver complexity, making them unsuitable for very low-complexity AMP terminals and negatively impacting communication signal performance. For other ambient energy sources, the energy harvesting rate may be slower than the energy consumed for data transmission, resulting in the AMP terminal being unable to continuously receive signals.

[0101] Based on this, in an embodiment of the present application, the terminal device can determine whether the terminal device has sufficient energy for data transmission based on its energy storage status.

[0102] It should be noted that the energy storage status of the terminal device can be understood as the power status, remaining power status, remaining energy status, etc. of the terminal device, and the embodiments of the present application do not limit this.

[0103] It should be understood that, because the terminal device's data transmission behavior / operations differ under different transmission states, the energy consumption corresponding to different transmission states also varies. In the implementation of this application, the terminal device's transmission state may be related to the terminal device's energy storage state. In other words, the terminal device may determine the appropriate transmission state based on its energy storage state.

[0104] In one example, when the energy storage state of a terminal device indicates that the current energy storage is above a certain threshold, the terminal device can perform normal data transmission. In this case, the terminal device's transmission state can be a continuous transmission state or a discontinuous transmission state. When the energy storage state of the terminal device indicates that the current energy storage is below a certain threshold, the terminal device cannot perform normal data transmission. In this case, the terminal device's transmission state can be a non-transmission state. At the same time, the terminal device needs to collect energy until its energy storage state meets certain conditions.

[0105] In another example, when the energy storage state of the terminal device represents that the current energy storage is high and can support continuous data transmission, the terminal device can determine that the transmission state is a continuous transmission state based on the energy storage state; when the energy storage state of the terminal device represents that the current energy storage is moderate, the terminal device can determine that the transmission state is a discontinuous transmission state based on the energy storage state; when the energy storage state of the terminal device represents that the current energy storage is low, the terminal device can determine that the transmission state of the terminal device is a non-transmission state based on the energy storage state.

[0106] In another example, when the energy storage state of the terminal device indicates that the current energy storage is higher than a certain threshold value, the terminal device can determine that the transmission state is a first discontinuous transmission state. When the energy storage state of the terminal device indicates that the current energy storage is lower than a certain threshold value, the terminal device can determine that the transmission state is a second discontinuous transmission state. The discontinuous transmission period of the first discontinuous transmission state is shorter than the discontinuous transmission period of the second discontinuous transmission state, and / or the duration of continuous transmission in the first discontinuous transmission state is longer than the duration of continuous transmission corresponding to the second discontinuous transmission state. It can be understood that in the second discontinuous transmission state, the terminal device can have more time to collect energy and consume less power.

[0107] It can be understood that in the transmission status determination method provided in the embodiment of the present application, the terminal device can determine the transmission status according to the energy storage status. In this way, the terminal device can reasonably utilize the energy storage status for transmission, thereby increasing the success rate of data transmission.

[0108] In an embodiment of the present application, the transmission status determination method provided in the embodiment of the present application may further include the following steps:

[0109] The network device determines a transmission state of the terminal device, where the transmission state includes multiple states, and different transmission states are related to the energy storage state of the terminal device.

[0110] It should be noted that the relevant descriptions of the above-mentioned transmission state and energy storage state in the embodiments of the present application can be understood by referring to the relevant descriptions in the above-mentioned embodiments. For the sake of brevity, they will not be repeated here.

[0111] It should be understood that on the network device side, the network device can synchronously determine the transmission status of the terminal device, and then perform data transmission with the terminal device based on the transmission status to ensure normal communication. For example, the network device can determine the transmission status of the terminal device based on indication information sent by the terminal device, or determine the transmission status of the terminal device based on a timer, or determine the transmission status of the terminal device based on the data transmission status of the terminal device. The specific determination method is described in detail in the following embodiments and is not described in detail here for the sake of brevity.

[0112] In an embodiment of the present application, the transmission state can change with the energy storage state of the terminal device. For example, referring to the process diagram of the reception state changing with the energy storage state shown in Figure 5, the transmission state may include transmission state 1 and transmission state 2. When the energy storage state of the terminal device is greater than E2, the terminal device may be in transmission state 1. For transmission state 1, the terminal device can perform discontinuous reception, wherein the period of discontinuous reception is a "DRX cycle", and the terminal device performs downlink signal or channel detection during the "On Duration" in each "DRX cycle". With the energy consumption caused by the detection of downlink signals or channels, when the energy storage drops from E1 to E2, the terminal device can switch the transmission state, and switch the transmission state from transmission state 1 to transmission state 2. Transmission state 2 is a non-transmission state. In transmission state 2, the terminal device can perform energy harvesting. When the energy storage reaches E1, the transmission state is switched, and the transmission state is switched from transmission state 2 to transmission state 1.

[0113] It is understood that the terminal device can switch between multiple transmission states, and accordingly, the network device can also synchronously determine the switching of the terminal device between multiple transmission states. The following details possible ways for the terminal device and the network device to determine the transmission state switching.

[0114] In one possible manner, the terminal device and the network device may determine the switching of the transmission state through indication information.

[0115] In some embodiments, the terminal device may send first information, and correspondingly, the network device may receive the first information sent by the terminal device. The first information may include one or more of the following:

[0116] Energy storage state switching information of terminal equipment;

[0117] Transmission state switching information of the terminal device.

[0118] It should be noted that the terminal device can send a first message to the network device when a transmission state switch is required. The first message indicates energy storage state switching information and / or transmission state switching information. In this way, after receiving the first message, the network device can determine the energy storage state and / or transmission state to which the terminal device is switched.

[0119] In some embodiments, the first information may be sent when the energy storage state of the terminal device is switched.

[0120] It is understandable that, because the transmission state of a terminal device is related to its energy storage state, when the terminal device's energy storage state switches, the terminal device's transmission state may also switch simultaneously. Therefore, when the terminal device's energy storage state switches, the terminal device can send a first message to the network device, indicating the energy storage state switching information and / or the transmission state switching information through the first message. In this way, after receiving the first message, the network device can determine the energy storage state and / or transmission state to which the terminal device has switched.

[0121] In some embodiments, the energy storage state switching information may include the energy storage state after the switch. For example, the first information may carry an index value of the energy storage state after the switch, or identification information of the energy storage state after the switch. Accordingly, the network device may obtain the transmission state associated with the energy storage state after the switch, thereby determining the transmission state of the terminal device after the switch.

[0122] It should be noted that if the number of energy storage states is 2, the energy storage state switching information may also indicate whether the energy storage state is switched. For example, the first information may include 1 bit of information, where bit 0 indicates not switching the energy storage state and bit 1 indicates switching the energy storage state; or, alternatively, bit 0 indicates switching the energy storage state and bit 1 indicates not switching the energy storage state.

[0123] In some embodiments, the transmission state switching information may include the transmission state of the terminal device after switching. For example, the first information may carry an index value of the transmission state after switching, or identification information of the transmission state after switching. The network device may determine the transmission state of the terminal device after switching based on the transmission state switching information.

[0124] It should be noted that if the number of transmission states is 2, the transmission state switching information may also indicate whether the transmission state is switched. Exemplarily, the first information may include 1 bit of information, where bit 0 indicates not switching the transmission state and bit 1 indicates switching the transmission state; or, bit 0 indicates switching the transmission state and bit 1 indicates not switching the transmission state.

[0125] Exemplarily, referring to the transmission state switching schematic diagram 1 shown in FIG6 , the transmission state may include transmission state 1 and transmission state 2. In transmission state 1, the terminal device may perform discontinuous reception, wherein the period of discontinuous reception is a “DRX cycle”, and the terminal device performs downlink signal or channel detection during the “On Duration” in each “DRX cycle”. Transmission state 2 is a non-transmission state, and the terminal device may not perform downlink signal and / or channel detection. When the energy storage state of the terminal device indicates that the current energy storage of the terminal device is less than a certain threshold value (for example, E2 in FIG5 ), the terminal device may send a first message to the network device, indicating to the network device that the energy storage state is E2 through the first message, or indicating to the network device that the transmission state 2 is through the first message. When the energy storage state of the terminal device indicates that the current energy storage of the terminal device is greater than a certain threshold value (for example, E1 in FIG5 ), the terminal device may also send a first message to the network device, indicating to the network device that the energy storage state is E1 through the first message, or indicating to the network device that the transmission state 2 is through the first message.

[0126] In some embodiments, the first information may also be used to indicate one or more of the following:

[0127] The duration that the terminal device is in the transmission state after switching;

[0128] Discontinuous transmission period in the switched transmission state;

[0129] The duration of continuous transmission in the discontinuous transmission period in the switched transmission state.

[0130] It is understandable that the terminal device can estimate the duration of the transmission state after the switch based on the current energy storage state and / or the energy collection time. In this way, the terminal device can indicate the duration of the transmission state after the switch to the network device through the first information. In addition, the terminal device can also indicate relevant parameters of the transmission state after the switch to the network device through the first information. For example, whether the transmission state after the switch is for data transmission, the discontinuous transmission period of the transmission state after the switch, and the duration of continuous transmission.

[0131] Exemplarily, the terminal device and the network device may predefine or preconfigure different DRX modes. Different DRX models may have different DRX parameters, such as a DRX cycle and an "On Duration" length. The terminal device may indicate in the first information an index value or identification information of the DRX mode corresponding to the switched transmission state.

[0132] In some embodiments, the first information may be carried by one or more of the following:

[0133] Uplink data channel (Physical Uplink Shared Channel, PUSCH);

[0134] Semi-persistently scheduled uplink control channel (Physical Uplink Control Channel, PUCCH);

[0135] Hybrid Automatic Repeat reQuest (HARQ-ACK) feedback information corresponding to the downlink data channel PDCCH;

[0136] Uplink Control Information (UCI)

[0137] In some embodiments, when a network device schedules uplink data transmission of a terminal device, the terminal device may carry first information in an uplink data channel PUSCH. Exemplarily, as shown in FIG6 , when the transmission state includes transmission state 1 and transmission state 2, the terminal device may carry 1 bit of information in the PUSCH to indicate the transmission state or energy storage state after switching. For example, bit 0 indicates transmission state 1, and bit 1 indicates transmission state 2. Or bit 0 indicates energy storage state 1, and bit 1 indicates energy storage state 2. Or bit 0 indicates not switching the transmission state, and bit 1 indicates switching the transmission state.

[0138] It should be noted that the first information can be carried in the physical layer payload of the PUSCH, or in the Media Access Control header (MAC header) of the PUSCH, or in the MAC Control Element (MAC CE). This embodiment of the present application does not limit this.

[0139] In some embodiments, when a network device adjusts the downlink data reception of a terminal device, the terminal device may carry the first information in the HARQ-ACK feedback information. Exemplarily, as shown in FIG6 , when the transmission state includes transmission state 1 and transmission state 2, the terminal device may carry 1 bit of information in the PUCCH while carrying the HARQ-ACK feedback information, indicating the transmission state or energy storage state after switching, for example, bit 0 represents the first receiving state, and bit 1 represents receiving state 2. Or bit 0 represents energy storage state 1, and bit 1 represents energy storage state 2. Or bit 0 indicates not switching the receiving state, and bit 1 indicates switching the receiving state.

[0140] In some embodiments, the terminal device may also carry the first information separately via PUCCH. It should be noted that the network device may semi-statically configure PUCCH resources for sending the first information for the terminal device via high-layer signaling, allowing the terminal device to report via the semi-statically configured PUCCH resources.

[0141] In some embodiments, the first information may be multiplexed with other periodic or aperiodic UCI feedback. For example, the first information may be reported in a Power Headroom Report (PHR) or a Channel State Information (CSI) report. The network can use this reported information to promptly obtain the energy storage status of the AMP terminal or receive state switching information.

[0142] It should be noted that for the scenario of switching from a non-transmission state (i.e., the terminal device does not transmit data in this transmission state, such as transmission state 2 shown in Figure 6) to other transmission states, due to the lack of downlink or uplink data scheduling, in this scenario, the terminal device can carry the first information alone based on the semi-statically scheduled PUCCH.

[0143] Through this method, the network device can determine the transmission state switching information of the terminal device in a timely manner according to the first information sent by the terminal device, thereby ensuring the correct transmission of data.

[0144] In some embodiments, the switching of the transmission state of the terminal device may also be instructed by the network device.

[0145] Exemplarily, the network device may send second information to the terminal device, and correspondingly, the terminal device may receive the second information sent by the network device, where the second information is used to indicate the transmission status.

[0146] It is understandable that the network device can independently determine the transmission state to be switched by the terminal device, and indicate the transmission state to be switched to the terminal device through the second information.

[0147] Exemplarily, the network device may determine the transmission state to be switched by the terminal device according to the energy storage state of the terminal device.

[0148] In some embodiments, the second information may carry an index value of the indicated transmission status, or identification information.

[0149] In some embodiments, the second information may further indicate the duration of time the terminal device is in the transmission state, the discontinuous transmission period of the transmission state, and the duration of continuous transmission within the discontinuous transmission period.

[0150] In some embodiments, before the network device sends the second information to the terminal device, it may also receive third information sent by the terminal device, wherein the third information is used to indicate the energy storage status of the terminal device.

[0151] It is understandable that the terminal device can report the energy storage status to the network device through the third information. In this way, the network device can determine the transmission status based on the energy storage status reported by the terminal device. Further, the network device can indicate the transmission status to the terminal device through the second information.

[0152] It should be noted that the terminal device may send the third information to the network device at a certain time period; or the terminal device may send the third information to the network device when the energy storage state changes. In this way, the network device can promptly determine the energy storage state of the terminal device based on the third information, thereby indicating the corresponding transmission state to the terminal device.

[0153] In another possible implementation, the terminal device and the network device may trigger the switching of the transmission state according to a timer.

[0154] In some embodiments, the transmission state may include a first transmission state and a second transmission state. When the first timer associated with the first transmission state times out, the terminal device may switch to the second transmission state; for the network side, when the first timer associated with the first transmission state times out, the network device may determine that the terminal device switches to the second transmission state.

[0155] The first timer may be started when the terminal device enters the first transmission state.

[0156] It should be noted that different transmission states may be associated with different timers. The duration of the timer associated with each transmission state may be the duration that the terminal device is in the transmission state, or the duration that the terminal device is in the energy storage state associated with the transmission state.

[0157] Among them, the duration of the timer associated with different transmission states can be predefined or configured by the network device, and the embodiment of the present application does not limit this.

[0158] It should also be noted that the duration of the timer associated with different transmission states may be related to one or more of the energy storage capability of the terminal device, the energy harvesting capability of the terminal device, the discontinuous transmission period corresponding to the associated transmission state, and the duration of continuous transmission within the discontinuous transmission period corresponding to the associated transmission state. In other words, the duration of the timer associated with different transmission states may be determined based on one or more of the energy storage capability of the terminal device, the energy harvesting capability of the terminal device, the discontinuous transmission period corresponding to the associated transmission state, and the duration of continuous transmission within the discontinuous transmission period corresponding to the associated transmission state.

[0159] For example, referring to the second transmission state switching diagram shown in FIG7 , the transmission state may include transmission state 1 and transmission state 2. When the terminal device is in transmission state 1, the main power consumption is due to blind detection and measurement of the downlink PDCCH. Regardless of whether the terminal device detects the PDCCH sent by the network device, after a certain period of time (i.e., the duration of Timer 1), the terminal device's energy storage will decrease, and it is necessary to switch to transmission state 2 to enable more energy harvesting. The duration of Timer 1 can be determined based on the DRX cycle of transmission state 1 and the "On Duration" duration. It is understandable that the longer the DRX cycle, or the shorter the "On Duration" duration, the less power the terminal device consumes in transmission state 1, the more opportunities for energy harvesting, and the corresponding Timer 1 duration can be longer. Conversely, the shorter the DRX cycle, or the longer the "On Duration" duration, the more power the terminal device consumes in transmission state 1, the fewer opportunities for energy harvesting, and the corresponding Timer 1 duration can be shorter.

[0160] In addition, when the terminal device is in transmission state 2, the terminal device can perform energy harvesting. After a certain period of time (i.e., the duration of timer 2), the energy storage state of the terminal device will reach a certain threshold value. At this time, the terminal device can switch to reception state 1 to continue blind detection and measurement of the downlink PDCCH. The duration of timer 2 can be determined based on the energy storage capacity and energy harvesting capability of the terminal device. The stronger the energy storage capacity of the terminal device, or the stronger the energy harvesting capability, the shorter the duration of timer 2 can be; conversely, the weaker the energy storage capacity of the terminal device, or the weaker the energy harvesting capability, the longer the duration of timer 2 can be.

[0161] It should be noted that the energy storage capacity of the terminal device may be related to the size and / or number of the energy storage units of the terminal device. In addition, the energy harvesting capacity of the terminal device may be related to the size and / or number of the energy harvesting units of the terminal device, and may also be related to the intensity of the ambient energy.

[0162] It should also be noted that before the terminal device and the network device switch the transmission state according to the timer, the following steps may also be included:

[0163] The terminal device sends fifth information to the network device, and correspondingly, the network device receives the fifth information sent by the terminal device; wherein the fifth information is used to indicate one or more of the following:

[0164] Energy storage capacity of terminal equipment;

[0165] Energy harvesting capabilities of terminal devices.

[0166] It can be understood that the terminal device can report its own capabilities to the network device in advance, so that the network device can determine the timer duration corresponding to each transmission state based on the capability information, and thus accurately determine the transmission state of the terminal device based on the timer duration corresponding to each transmission state to ensure the correct transmission of data.

[0167] It should be noted that the fifth information can be carried through the terminal device capability information or through dedicated signaling, and the embodiments of the present application do not impose any restrictions on this.

[0168] In some embodiments, the above-mentioned transmission state may only include the above-mentioned first transmission state and second transmission state, and the transmission state switches between the first transmission state and the second transmission state. Specifically, when the terminal device enters the first transmission state, the terminal device and / or the network device may start a timer associated with the first transmission state, and when the timer associated with the first transmission state times out, it is determined to switch from the first transmission state to the second transmission state. At the same time, when switching to the second transmission state, a timer associated with the second transmission state may be started, and when the timer associated with the second transmission state times out, the second transmission state is switched back to the first transmission state.

[0169] In some embodiments, the transmission states described above include not only the first and second transmission states but also other transmission states. The multiple transmission states can be arranged in a certain order (for example, they can be arranged according to the energy levels represented by the energy storage states associated with the multiple transmission states), and the terminal device can switch between the multiple transmission states. Exemplarily, the transmission states can also include a third transmission state, and the first, second, and third transmission states can be arranged in a certain order. For example, the first transmission state can be switched to the second transmission state, the second transmission state can be switched to the third transmission state, and the third transmission state can be switched back to the first transmission state. Specifically, when the terminal device enters the first transmission state, the terminal device and / or the network device can start a timer associated with the first transmission state. When the timer associated with the first transmission state expires, the device determines to switch from the first transmission state to the second transmission state. Simultaneously, the device can start a timer associated with the second transmission state. When the timer associated with the second transmission state expires, the device determines to switch from the second transmission state to the third transmission state. Simultaneously, the device can start a timer associated with the third transmission state. When the timer associated with the third transmission state expires, the device determines to switch from the third transmission state back to the first transmission state, and starts the timer associated with the first transmission state.

[0170] It should be noted that the “first transmission state”, “second transmission state” and “third transmission state” mentioned in the embodiments of the present application are only for distinguishing different objects and are not used to limit specific transmission states.

[0171] It will be appreciated that in embodiments of the present application, upon determining that a terminal device has entered a certain transmission state, the terminal device and the network device may start a timer associated with that transmission state. Upon expiration of the timer, the device switches to the next transmission state. Triggering transmission state switching by a timer can reduce signaling overhead between the terminal device and the network device.

[0172] In some embodiments, before the first timer times out, if the energy storage state of the terminal device meets a first condition, the terminal device may restart the first timer; wherein the first condition is determined based on the energy storage state associated with the first transmission state.

[0173] That is to say, when the terminal device is in the first transmission state, if the first timer associated with the first transmission state has not expired, and the energy storage state of the terminal device meets the first condition associated with the first transmission state, the terminal device can restart the first timer to extend the time in the first transmission state.

[0174] For example, when the first transmission state is a continuous transmission state or a discontinuous transmission state, the corresponding first condition may be that the current energy storage of the terminal device is greater than the energy storage required for the first transmission state within the first timer duration. When the first transmission state is a non-transmission state, the corresponding first condition may be that the current energy storage of the terminal device is insufficient, that is, the energy storage of the terminal device is less than a certain threshold value.

[0175] It is understandable that in a scenario where transmission state switching is triggered based on a timer, the terminal device can restart the timer associated with a certain transmission state when certain conditions are met, thereby extending the time the terminal device stays in the transmission state.

[0176] In some embodiments, on the network side, the network device may restart a timer associated with a transmission state based on the indication information sent by the terminal device. Specifically, the terminal device may send fourth information to the network device, where the fourth information is used to indicate one or more of the following:

[0177] The energy storage state of the terminal device meets the first condition;

[0178] Restart the first timer.

[0179] It is understandable that the network device can restart the timer based on the fourth information sent by the terminal device. The fourth information can indicate that the energy storage state of the terminal device meets the first condition. By indicating that the energy storage state of the terminal device meets the first condition, the network device is triggered to restart the first timer. In addition, the fourth information can also directly instruct the network device to restart the first timer.

[0180] In one example, referring to the third transmission state switching diagram shown in FIG8 , the transmission state may include transmission state 1 and transmission state 2. During the operation of timer 1 associated with transmission state 1, if the energy storage state of the terminal device indicates that the current energy storage is sufficient to support data transmission within the first timer duration, the terminal device may restart timer 1. Simultaneously, the terminal device may send fourth information to the network device, instructing the network device to restart timer 1 via the fourth information.

[0181] In another example, referring to the fourth transmission state switching diagram shown in FIG9 , during the operation of timer 2 associated with transmission state 2, if the energy storage state of the terminal device indicates that the current energy storage is insufficient and cannot continue to support data transmission in transmission state 1, the terminal device can restart timer 2. At the same time, the terminal device can send a fourth message to the network device, instructing the network device to restart timer 2.

[0182] Through this method, the network device and the terminal device can determine the switching of the transmission state based on the timer to ensure the correct transmission of data.

[0183] In another possible implementation, the terminal device and the network device may trigger switching of the transmission state according to the data transmission situation.

[0184] In some embodiments, the transmission state includes a first transmission state and a second transmission state. In the first transmission state, if the amount of data transmitted by the terminal device meets a first threshold associated with the first transmission state, the terminal device switches to the second transmission state. On the network side, when the terminal device is in the first transmission state, if the amount of data transmitted by the terminal device meets the first threshold associated with the first transmission state, the network device may determine that the terminal device switches to the second transmission state.

[0185] It should be noted that different transmission states may be associated with different thresholds, which may be the maximum number of data transmissions that can be processed by the energy storage state corresponding to the terminal device under the associated transmission state.

[0186] It should be understood that after a network device schedules a terminal device's downlink or uplink transmission, the terminal device consumes a certain amount of stored energy for received demodulation, HARQ-ACK feedback, or data transmission. After a terminal device transmits a certain amount of data, it can be considered that the terminal device's stored energy status has changed. At this point, the terminal device can switch its transmission state.

[0187] That is, the terminal device and the network device can count the amount of data transmitted by the terminal device in the first transmission state. If the amount of transmitted data meets a first threshold associated with the first transmission state, it is determined that the transmission state is switched from the first transmission state to the second transmission state.

[0188] It should be noted that the thresholds associated with different transmission states can be predefined or configured by the network device, and the embodiments of the present application do not impose any restrictions on this.

[0189] It should also be noted that the thresholds associated with different transmission states may be related to one or more of the following: the energy storage capability of the terminal device, the energy harvesting capability of the terminal device, the discontinuous transmission period corresponding to the associated transmission state, and the duration of continuous transmission within the discontinuous transmission period corresponding to the associated transmission state. In other words, the thresholds associated with different transmission states may be determined based on one or more of the following: the energy storage capability of the terminal device, the energy harvesting capability of the terminal device, the discontinuous transmission period corresponding to the associated transmission state, and the duration of continuous transmission within the discontinuous transmission period corresponding to the associated transmission state.

[0190] Exemplarily, referring to the fifth transmission state switching diagram shown in FIG10 , the transmission state may include transmission state 1 and transmission state 3. Both transmission state 1 and transmission state 3 are DRX states, wherein the cycle of transmission state 1 is DRX cycle 1, and the cycle of transmission state 3 is DRX cycle 2; the continuous transmission time of transmission state 1 is On Duration 1, and the continuous transmission time of transmission state 3 is On Duration 2.

[0191] When a terminal device is in Transmission State 1, each time it transmits data, it consumes a certain amount of energy for demodulation, HARQ-ACK feedback, or data transmission. When the number of data transmissions exceeds Threshold 1, the terminal device's energy storage decreases, and it needs to switch to Transmission State 2 to enable more energy harvesting. The duration of Threshold 1 can be determined based on the DRX cycle and "On Duration" duration of Transmission State 1. It will be appreciated that a longer DRX cycle or a shorter "On Duration" duration reduces the terminal device's power consumption in Transmission State 1, leading to more opportunities for energy harvesting and, accordingly, a greater number of data transmissions that can be supported, and a larger Threshold 1. Conversely, a shorter DRX cycle or a longer "On Duration" duration increases the terminal device's power consumption in Transmission State 1, leading to fewer opportunities for energy harvesting and, accordingly, a smaller number of data transmissions that can be supported, and a smaller Threshold 1 can be used.

[0192] Additionally, when the terminal device is in Transmission State 3, it can perform energy harvesting during the sleep period of each DRX cycle. In Transmission State 3, if the amount of data transmitted is less than Threshold 2, the terminal device harvests more energy. Threshold 2 can be determined based on the terminal device's energy storage and energy harvesting capabilities. The greater the terminal device's energy storage or energy harvesting capabilities, the greater Threshold 2 can be. Conversely, the weaker the terminal device's energy storage or energy harvesting capabilities, the smaller Threshold 2 can be.

[0193] It should also be noted that before the terminal device and the network device switch the transmission state according to the timer, the following steps may also be included:

[0194] The terminal device sends fifth information to the network device, and correspondingly, the network device receives the fifth information sent by the terminal device; wherein the fifth information is used to indicate one or more of the following:

[0195] Energy storage capacity of terminal equipment;

[0196] Energy harvesting capabilities of terminal devices.

[0197] It can be understood that the terminal device can report its own capabilities to the network device in advance, so that the network device can determine the threshold corresponding to each transmission state based on the capability information, and thus accurately determine the transmission state of the terminal device based on the threshold corresponding to each transmission state to ensure the correct transmission of data.

[0198] It should be noted that the fifth information can be carried through the terminal device capability information or through dedicated signaling, and the embodiments of the present application do not impose any restrictions on this.

[0199] In some embodiments, the above-mentioned transmission state may only include a first transmission state and a second transmission state, and the transmission state switches between the first transmission state and the second transmission state. Specifically, the terminal device and / or the network device may count the number of data transmissions in the first transmission state, and when the number of data transmissions in the first transmission state meets the first threshold associated with the first transmission state, it is determined to switch from the first transmission state to the second transmission state. At the same time, after switching to the second transmission state, the terminal device and / or the network device may count the number of data transmissions in the second transmission state, and when the number of data transmissions meets the second threshold associated with the second transmission state, it is switched from the second transmission state back to the first transmission state.

[0200] In some embodiments, the transmission states described above include not only the first transmission state and the second transmission state, but also other transmission states. The multiple transmission states can be arranged in a certain order (for example, they can be arranged according to the energy level represented by the energy storage state associated with each of the multiple transmission states), and the terminal device can switch between the multiple transmission states. Exemplarily, the transmission state can also include a third transmission state, and the first transmission state, the second transmission state, and the third transmission state can be arranged in a certain order. For example, the first transmission state can be switched to the second transmission state, the second transmission state can be switched to the third transmission state, and the third transmission state can be switched back to the first transmission state. Specifically, the terminal device and / or network device can count the number of data transmissions in the first transmission state, and when the number of data transmissions in the first transmission state meets a first threshold associated with the first transmission state, determine to switch from the first transmission state to the second transmission state. Simultaneously, after switching to the second transmission state, the terminal device and / or network device can count the number of data transmissions in the second transmission state, and when the number of data transmissions meets a second threshold associated with the second transmission state, switch from the second transmission state to the third transmission state. The terminal device and / or network device can count the number of data transmissions in the second transmission state, and when the number of data transmissions meets a third threshold associated with the third transmission state, switch from the third transmission state to the first transmission state.

[0201] It should be noted that the “first transmission state”, “second transmission state” and “third transmission state” mentioned in the embodiments of the present application are only for distinguishing different objects and are not used to limit specific transmission states.

[0202] As can be seen, in the embodiments of the present application, when a terminal device determines that it has entered a certain transmission state, the terminal device and the network device can count the number of data transmissions in that transmission state. When the number of data transmissions meets the threshold associated with that transmission state, the device can switch to the next transmission state. By triggering the switching of transmission states based on the statistical number of transmissions, the signaling overhead of the terminal device and the network device can be reduced.

[0203] In some embodiments, in the first transmission state, if the amount of data transmitted by the terminal device does not meet the first threshold when the second timer times out, the terminal device restarts the second timer; for the network side, in the first transmission state, if the amount of data transmitted by the terminal device does not meet the first threshold when the second timer times out, the network device may restart the second timer.

[0204] It should be noted that the second timer is started when the terminal device enters the first transmission state.

[0205] It is understandable that the terminal device and / or the network device can count the number of data transmissions in the current transmission state within a certain time period to determine whether the number of data transmissions in the transmission state meets a threshold associated with the current transmission state. The terminal device and / or the network device can count the number of data transmissions in the current transmission state based on a second timer.

[0206] Furthermore, when the second timer times out, if the amount of data transmitted by the terminal device does not meet the first threshold, the terminal device may restart the second timer to extend the time in the current transmission state.

[0207] It should be noted that the above three methods of determining the transmission status can be implemented in combination.

[0208] In one example, the terminal device and the network device can determine the switching of the transmission state based on the indication information and the timer. Specifically, if the transmission state includes a first transmission state and a second transmission state, when the first timer associated with the first transmission state times out, the network device can determine that the terminal device should switch from the first transmission state to the second transmission state. If the terminal device sends a first message to the network device before the first timer times out, indicating the energy storage state switching information of the terminal device and / or the transmission state switching information of the terminal device, the network device can respond to the first message and determine that the terminal device has switched the transmission state, without having to wait until the first timer times out to determine that the transmission state of the terminal device has switched.

[0209] In another example, the terminal device and the network device can determine the switching of the transmission state based on the indication information and the data transmission situation. Specifically, if the transmission state includes a first transmission state and a second transmission state, in the first transmission state, if the amount of data transmitted by the terminal device meets the first threshold associated with the first transmission state, it is determined to switch to the second transmission state. Before the amount of data transmitted by the terminal device meets the first threshold, if the terminal device sends a first message to the network device to indicate the energy storage state switching information of the terminal device, and / or the transmission state switching information of the terminal device, the network device can respond to the first message and determine that the terminal device has switched its transmission state, without having to wait until the amount of data transmission meets the first threshold to determine that the transmission state of the terminal device has switched.

[0210] In another example, the terminal device and the network device may determine whether to switch the transmission state based on a timer and data transmission conditions. Specifically, if the transmission state includes a first transmission state and a second transmission state, the network device may determine that the terminal device should switch from the first transmission state to the second transmission state when a first timer associated with the first transmission state times out, or when the amount of data transmitted by the terminal device meets a first threshold associated with the first transmission state.

[0211] To sum up, through the transmission status determination method provided in the embodiment of the present application, the terminal device and the network device can determine the transmission status according to the energy storage status of the terminal device. In this way, the terminal device and the network device can reasonably utilize the energy storage status of the terminal device for transmission, thereby increasing the success rate of data transmission.

[0212] The method provided in the embodiment of the present application is described in detail below in conjunction with specific application scenarios.

[0213] In an embodiment of the present application, the terminal device is an AMP terminal. This embodiment, taking into account the characteristics of the AMP terminal's energy source, proposes a discontinuous reception method that rationally utilizes stored energy for discontinuous reception, thereby increasing the success rate of data transmission. The technical solution of this embodiment of the present application includes the following:

[0214] The AMP terminal may determine the receiving state of the AMP terminal according to the energy storage state of the AMP terminal.

[0215] It should be noted that, using RF energy harvesting as an example, the AMP terminal collects radio waves through the RF energy harvesting module, thereby obtaining radio energy and storing it in an energy storage unit. Once the energy storage unit has sufficient energy, it can drive low-power circuits for operations such as forward link signal demodulation and reverse link signal modulation and transmission.

[0216] For AMP terminals that harvest energy through RF signals, the energy received by their receivers can generally only be used for either information demodulation or energy harvesting. That is, before receiving an RF signal, the AMP terminal must decide whether to process the RF signal for information demodulation or energy harvesting. If the current energy storage level allows, the AMP terminal can use stored energy for information demodulation without energy harvesting. The AMP terminal's processing of the RF signal depends on whether it is currently in energy harvesting or communication mode. These two modes are often temporally separate, meaning they occur at different times. This is partly because the communication signal and the RF signal used for energy harvesting may not be in the same frequency band. Even if they are in the same frequency band, energy harvesting and communication can proceed simultaneously, requiring the received signal power to be divided, with one portion used for information demodulation and the other for energy harvesting. However, these approaches require high receiver complexity, making them unsuitable for AMP terminals with very low complexity and negatively impacting communication signal performance.

[0217] For other environmental energy sources, the speed of energy collection may be lower than the speed of energy consumed by communication, causing the AMP terminal to be unable to continue receiving.

[0218] Therefore, when the AMP terminal's energy storage level exceeds a certain threshold, it can perform continuous or discontinuous reception like a traditional terminal. This reception state is defined as AMP terminal reception state 1. When the AMP terminal's energy storage level falls below a certain threshold and cannot support reception state 1, the AMP terminal must store energy until it reaches a certain energy storage level. During this period, the AMP terminal must enter reception state 2.

[0219] Specifically, the reception state 1 may be a continuous reception state or a discontinuous reception state 1. Parameters of the discontinuous reception state 1 may be configured through high-layer signaling, such as the discontinuous reception period and "On Duration" length.

[0220] Specifically, reception state 2 can be a non-reception state or discontinuous reception state 2. The parameters of discontinuous reception state 2 can be configured through higher-layer signaling, including the discontinuous reception period and "On Duration" length. Preferably, compared to discontinuous reception state 1, the discontinuous reception period in the discontinuous reception state can be longer, and the "On Duration" can be shorter. Therefore, in the second discontinuous reception state, the AMP terminal can have more opportunities to harvest energy and consume less power.

[0221] The following describes how to switch the receiving status of the AMP terminal.

[0222] In one embodiment, the AMP terminal and the network device may determine the switching of the receiving state based on the indication information.

[0223] When the AMP terminal's energy storage state reaches or falls below a certain threshold, it needs to send indication information (i.e., the first information described above) to the network. The indication information may include energy storage status or receiving state switching information. When the AMP terminal is in receiving state 1, the main power consumption comes from the detection and measurement of the downlink PDCCH. When the network schedules the data transmission of the AMP terminal through signaling, the AMP terminal can carry the indication information through the uplink channel.

[0224] Optionally, when the network schedules the reception of downlink data by an AMP terminal, the AMP terminal may carry indication information in the HARQ-ACK feedback information to indicate the current energy storage state or reception state information. For example, while carrying the HARQ-ACK feedback information in the PUCCH, 1 bit of information may also be carried to indicate the subsequent reception state, for example, bit 0 indicates reception state 1, and bit 1 indicates reception state 2. Alternatively, bit 0 indicates energy storage state 1, and bit 1 indicates energy storage state 2. Alternatively, bit 0 indicates not switching the reception state, and bit 1 indicates switching the reception state.

[0225] Optionally, when the network schedules uplink data transmission of an AMP terminal, the AMP terminal may carry indication information in the uplink data channel to indicate the current energy storage status or reception status information. For example, 1 bit of information may be carried in the PUSCH, which may be carried in the physical layer payload, or in the MAC header, MAC CE, etc.

[0226] Optionally, the AMP terminal can also carry the indication information separately through the PUCCH. The network upper layer can semi-statically configure the PUCCH resources used to send the indication information to allow the AMP terminal to report through the resources. This is similar to the existing SR sending method.

[0227] Optionally, this indication information can be multiplexed with other periodic or aperiodic UCI feedback, such as PHR feedback, or multiplexed with CSI report. Through this reported information, the network can timely obtain the energy storage status of the AMP terminal or receive state switching information.

[0228] Furthermore, the above-mentioned indication information may also indicate the duration for which the AMP terminal is in receiving state 2. The AMP terminal indicates the duration for which the AMP terminal needs to be in receiving state 2 based on an estimate of the energy storage state or energy collection time. Alternatively, the indication information may also indicate a DRX mode for the AMP terminal to be in receiving state 2. The DRX mode has predefined or network-configured DRX parameters, such as a DRX cycle and an "On Duration" length.

[0229] Furthermore, the indication information may be sent by the AMP terminal to the network, or may be sent by the network to the AMP terminal. Specifically, the network may determine whether to send indication information to instruct the AMP terminal to switch the receiving state based on the energy storage status report obtained from the AMP terminal.

[0230] In one embodiment, the AMP terminal and the network device may determine the switching of the receiving state based on a timer.

[0231] As shown in Figure 7, when an AMP terminal is in Receiving State 1 (i.e., Transmitting State 1 in Figure 7), the primary power consumption comes from blind detection and measurement of the downlink PDCCH. Regardless of whether a PDCCH sent to it is detected, after a certain period of time, the AMP terminal's energy storage will decrease, and it will need to switch to Receiving State 2 (i.e., Transmitting State 2 in Figure 7) to collect more energy.

[0232] Switching from receiving state 1 to receiving state 2 can be performed according to timer 1. The duration of timer 1 can be configured by the network or a preset value. Specifically, the preset value can be related to the energy storage capacity or energy collection capacity of the AMP terminal. The energy collection capacity can be related to the capabilities of the AMP terminal itself or to the intensity of the ambient energy. It can also be related to the DRX cycle of receiving state 1. The longer the DRX cycle, the less power the AMP terminal consumes in receiving state 1, the more opportunities for energy collection, and the corresponding timer 1 can be longer.

[0233] Specifically, timer 1 starts when the AMP terminal enters receiving state 1. When timer 1 times out, the AMP terminal switches to receiving state 2. Furthermore, the timer can be restarted under certain conditions, based on the indication information fed back by the AMP terminal. When the energy storage state of the AMP terminal meets certain conditions, the feedback indication information can instruct the network to restart the timer, thereby extending the time the AMP terminal remains in receiving state 1.

[0234] In addition, the AMP terminal can also determine the duration of being in receiving state 2 based on timer 2. The length of timer 2 can be configured through high-level signaling, or it can be a preset value. Specifically, the preset value can be related to the energy storage capacity or energy collection capacity of the AMP terminal. The energy collection capacity can be related to the capacity of the AMP terminal itself, or it can be related to the intensity of the ambient energy. It can also be related to the next DRX cycle in receiving state 2. The longer the DRX cycle, the less power the AMP terminal consumes in receiving state 2, the more opportunities for energy collection, and the shorter the corresponding timer length can be.

[0235] Specifically, the timer starts when the AMP terminal enters receiving state 2. When timer 2 times out, the AMP terminal switches to receiving state 1. Furthermore, the timer 2 can be restarted under certain conditions. For example, it is restarted based on the indication information fed back by the AMP terminal. When the energy storage state of the AMP terminal meets certain conditions, the network can be instructed to restart the timer through the feedback indication information to extend the time the AMP terminal is in receiving state 2. For example, when the energy storage state of the AMP terminal is insufficient, the network can be instructed to restart the timer through the indication information to extend the time the AMP terminal is in receiving state 2 for energy collection.

[0236] In yet another embodiment, the AMP terminal and the network device may determine the switching of the reception state based on the detection result of the PDCCH.

[0237] It should be understood that after the network schedules the downlink or uplink transmission of the AMP terminal, the AMP terminal needs to consume a certain amount of energy for demodulation, HARQ-ACK feedback, or data transmission. After the network performs a certain number of scheduling, the AMP terminal switches to receiving state 2. The number of scheduling can be configured by the network or a preset value. Specifically, the preset value may be related to the energy storage capacity or energy collection capacity of the AMP terminal. The energy collection capacity may be related to the capacity of the AMP terminal itself, or it may be related to the intensity of the ambient energy. It may also be related to the DRX cycle in receiving state 1. The longer the DRX cycle, the more opportunities the AMP terminal has to perform energy collection in receiving state 1, and the more data scheduling that can be supported accordingly.

[0238] When the AMP terminal is in Receiving State 2, such as DRX State 2, if the network-scheduled downlink data transmission or the uplink transmission required by the AMP terminal is very low, the need for the AMP terminal to switch to Receiving State 1 is low, and the duration of the AMP terminal in Receiving State 2 can be extended. This method can be combined with a timer method. During the timer startup period, if the number of received PDCCHs falls below a certain threshold, the timer can be restarted to extend the duration of the AMP terminal in Receiving State 2.

[0239] In summary, when the cellular network supports access to AMP devices, since the energy of the AMP devices comes from the environment and the AMP devices have limited energy storage capacity, the transceiver status of the AMP terminal cannot be well matched with the existing DRX mechanism, which will cause data transmission and reception failure. The method provided in the embodiment of the present application can determine the receiving state of the AMP terminal by the energy storage state of the AMP terminal. In this way, the energy storage of the AMP terminal is matched with the receiving state, and the energy storage can be reasonably used for data transmission, thereby improving the efficiency of data transmission.
