Optionally, the first device may be configured to collect energy and communicate based on the collected energy. The first device may be, for example, a terminal.

[0316] The following embodiments of the present disclosure may be applied to the communication system 100 shown in Figure 1, or a portion thereof, but are not limited thereto. The entities shown in Figure 1 are illustrative only. The communication system may include all or part of the entities shown in Figure 1, or may include other entities outside of Figure 1. The number and form of the entities may be arbitrary. The connection relationship between the entities is illustrative only. The entities may be connected or disconnected, and the connection may be in any manner, including direct or indirect, wired or wireless.
[0317] The embodiments of the present disclosure can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), future radio access (FRA), new radio access technology (RAT), new radio (NR), new radio access (NX), future generation radio access (FX), Global System for Mobile Communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X), systems utilizing other communication methods, and next-generation systems based on and extending these methods. Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).
[0318] Optionally, the new device that collects energy and communicates based on the collected energy may be referred to as an Ambient Internet of Things (A-IoT) device. Optionally, the communication methods of the A-IoT device may include, for example, the following:
[0319] The first is that the terminal sends an electromagnetic wave (continuous wave, CW) signal to the A-IoT device. This CW signal can stimulate the A-IoT device to achieve backscatter communication. Specifically, after receiving the CW signal, the A-IoT device will obtain energy (such as energy to activate the receiving and processing module inside the A-IoT device). Afterwards, the A-IoT device will backscatter the CW signal based on this energy. When backscattering the CW signal, the terminal can superimpose the information to be sent on the backscattered signal by changing the frequency, phase, and amplitude of the electromagnetic wave of the CW signal to achieve the purpose of sending information, thereby achieving backscatter communication.
[0320] Second, the terminal sends an Energy Source (ES) signal to the A-IoT device. This ES signal can be used to charge the A-IoT device. Optionally, the A-IoT device can use the energy charged by the ES signal to perform backscatter communication with a higher power. Alternatively, the A-IoT device can actively transmit based on the energy charged by the ES signal. This active transmission can be understood as active transmission without CW signal excitation. The first and second methods described above are specific methods for A-IoT devices to collect energy and communicate based on the collected energy.
[0321] The third type is that the terminal sends a downlink transmission (DT) signal to the A-IoT device, and the DT signal includes downlink information that the terminal wants to send to the A-IoT device.
[0322] Fourth, the A-IoT device sends an uplink reception (UR) signal to the terminal. The UR signal includes the uplink information to be sent by the A-IoT device. Optionally, the UR signal can be sent by the A-IoT device based on the stimulation of the CW signal. In this case, the UR signal is the signal obtained after the A-IoT device backscatters the CW signal. Alternatively, the UR signal can be actively transmitted by the A-IoT device based on stored energy.
[0323] It should be noted that, optionally, the above-mentioned CW signal can also be regarded as an ES signal, which is used to charge the A-IoT device so that the A-IoT device can realize backscatter communication based on the charged energy.
[0324] Optionally, in some embodiments, the above-mentioned A-IoT devices may include three categories, namely A-IoT device A, A-IoT device B, and A-IoT device C. Among them, A-IoT device A does not support energy storage or only supports a small amount of energy storage, and A-IoT device A can be used to implement backscatter communication, which has the lowest complexity and low power consumption.
[0325] A-IoT device B supports energy storage and is used to implement backscatter communication. Optionally, the energy that A-IoT device B can store is relatively limited. A-IoT device B can use the stored energy to use greater power for backscatter communication. Its complexity and power consumption are higher than those of A-IoT device A, but still maintain a relatively low level.
[0326] The A-IoT device C supports energy storage and can actively transmit information based on the stored energy. Optionally, when the A-IoT device C actively transmits information, it can first perform power amplification through a power amplifier and then transmit the information. Among them, the A-IoT device C generally needs to store more energy to support the above-mentioned active transmission.
[0327] Optionally, the aforementioned CW signal can be used by A-IoT device A and A-IoT device B to implement backscatter communication. The aforementioned ES signal can be used by A-IoT device B and A-IoT device C to charge A-IoT device B and A-IoT device C. Optionally, for A-IoT device A, due to its very limited supported energy storage capacity, ES signals other than CW can be undefined. Alternatively, ES signals can be used by A-IoT device A for backscatter communication.
[0328] As can be seen from the above, the signals required for communication between a terminal and an A-IoT device include at least one of the following: CW, ES, DT, and UR signals. The specific transmission method used by the terminal to send CW, ES, and DT signals to the A-IoT device, as well as the specific reception method used by the terminal to receive the UR signal from the A-IoT device, are currently urgent issues that need to be addressed to ensure successful and efficient communication between the terminal and the A-IoT device.
[0329] FIG2A is an interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG2A , the embodiment of the present disclosure relates to a communication method for use in a communication system 100, the method comprising:
[0330] Step 2101: The network device configures a first sending mode.
[0331] Optionally, the network device may configure the first transmission mode for at least one terminal; the terminal may receive the first transmission mode configured by the network device. Optionally, in some embodiments, the network device may configure the first transmission mode via high-layer signaling, such as Radio Resource Control (RRC) signaling.
[0332] Optionally, the above-mentioned first sending mode can be: the sending mode when the terminal sends the first signal to the first device; optionally, the first device can be used to collect energy and communicate based on the collected energy; the first device can be, for example, the aforementioned A-IoT device (such as A-IoT device A, A-IoT device B or A-IoT device C), wherein, for a detailed introduction to “the first device collects energy and communicates based on the collected energy”, please refer to the description before the embodiment of Figure 2A, which will not be repeated here. Optionally, the first signal can be used to charge the first device, and the first signal can be a continuous constant amplitude wave (such as a continuous constant amplitude sine wave), for example, the first signal can be the aforementioned ES signal. For a detailed introduction to the ES signal, please refer to the description before the embodiment of Figure 2A, which will not be repeated here.
[0333] Optionally, in some embodiments, the first sending mode may be omnidirectional sending, where “omnidirectional sending” may be understood as sending the first signal in all directions.
[0334] Alternatively, in other embodiments, the first transmission mode may be directional transmission in a first direction; wherein the first direction may cover part or all of the first device. Alternatively, in some embodiments, the first directions configured by the network device to different terminals may be the same or different. Furthermore, when the first direction covers part of the first device, the first directions of different terminals may or may not cover the same first device.
[0335] Optionally, in some further embodiments, the first transmission mode may be: directional transmission in a second direction; wherein the second direction may cover at least one first device group, wherein the first device group may include at least one first device, and different first device groups may include different or partially identical first devices. Optionally, in some embodiments, the second directions configured by the network device to different terminals may be different or the same, and the second directions of different terminals may or may not repeatedly cover the same first device group.
[0336] Step 2102: The terminal determines a first sending method.
[0337] Optionally, the terminal may determine the first sending mode based on the configuration of the network device, and / or the terminal may determine the first sending mode based on a protocol pre-definition.
[0338] For a detailed description of the first sending method, please refer to the above embodiment description.
[0339] Step 2103: The terminal sends a first signal based on the first sending mode.
[0340] Optionally, when the first sending mode is different, the execution process of step 2103 will also be different.
[0341] Specifically, in some embodiments, when the first transmission mode is "omnidirectional transmission," the terminal may transmit the first signal in all directions based on the first transmission mode. In this case, the first signal transmitted by the terminal can be received by all first devices. Furthermore, in some embodiments, when multiple terminals want to communicate with the first device, the multiple terminals may simultaneously transmit the first signal omnidirectionally. In this case, the first signals transmitted by the multiple terminals can be received by all first devices, thereby improving the terminal charging performance.
[0342] Optionally, in other embodiments, when the first transmission mode is "directional transmission in a first direction," when the terminal transmits the first signal based on the first transmission mode, the terminal may transmit the first signal directionally only in the first direction, and not transmit the first signal in directions other than the first direction. Optionally, the first direction may cover part or all of the first devices. When the first direction covers part of the first devices, the first signal directionally transmitted by the terminal in the first direction can only be received by the part of the first devices covered by the first direction; when the first direction covers all of the first devices, the first signal directionally transmitted by the terminal in the first direction can be received by all of the first devices. Optionally, in some embodiments, when multiple terminals want to communicate with the first device, the first directions of different terminals may be different or the same, and different terminals may simultaneously transmit the first signal directionally in their respective first directions. Optionally, when multiple terminals want to communicate with the first device and the first direction covers part of the first devices, the first directions of different terminals may overlap or not overlap the same first device. When the first directions of different terminals overlap the same first device, the overlapped first device can simultaneously receive the first signals sent by multiple terminals. Also, when the first directions of different terminals do not repeatedly cover the same first device, by having a sufficient number of terminals send the first signal simultaneously in the first direction, all first devices can receive the first signal, thereby achieving full coverage of the first device by the first signal. When the first device is charged using the first signal, the performance of charging the first device can be ensured.
[0343] Optionally, in some further embodiments, when the first transmission mode is "directional transmission in the second direction," when the terminal transmits the first signal based on the first transmission mode, it may be directionally transmitting the first signal only in the second direction, and not transmitting the first signal in directions other than the second direction. Optionally, the second direction may cover at least one first device group, wherein the first signal directionally transmitted by the terminal in the second direction may be received by the first device in the at least one first device group covered by the second direction. Optionally, in some embodiments, when multiple terminals want to communicate with the first device, the second directions of different terminals may be different or the same, and different terminals may simultaneously transmit the first signal directionally in their respective second directions. Furthermore, the second directions of different terminals may overlap or not overlap the same first device group. When the second directions of different terminals overlap the same first device group, the first device in the overlapped first device group may simultaneously receive the first signals transmitted by multiple terminals. In addition, when the second directions of different terminals do not repeatedly cover the same group of first devices, when the first signal is sent in the second direction by a sufficient number of terminals respectively, all first devices can receive the first signal, thereby achieving full coverage of the first signal for the first devices. When the first signal is used to charge the first device, the performance of charging the first device can be ensured.
[0344] Furthermore, in some embodiments, since the above-mentioned terminal and / or first device usually moves, the relative direction between the terminal and the first device will change. At this time, in order to ensure that the first signal can be accurately sent to the corresponding first device, it is usually necessary to update the first direction or the second direction when the first signal is sent in a directionally manner in real time, so that the first direction or the second direction can track and cover the moving first device in real time.
[0345] Specifically, in some embodiments, the above-mentioned real-time update method of the first direction can be: the terminal tracks in real time the direction change of the first device to be covered by the transmission of the terminal's first signal relative to the terminal. For example, the terminal can obtain the real-time position of the first device from the network device and / or the first device, and determine the direction change of the first device to be covered relative to the terminal (or terminal antenna) based on the real-time position of the first device and the real-time position of the terminal. After that, the terminal can update the first direction in real time based on the direction change of the first device to be covered relative to the terminal, so that the first direction can cover the first device to be covered in real time.
[0346] Optionally, the aforementioned real-time updating method for the second direction may include: the terminal tracking, in real time, changes in the direction of a first device in the first device group required to be covered by the transmission of the first signal by the terminal relative to the terminal, and updating the second direction in real time based on the changes in the direction of the first device in the first device group required to be covered relative to the terminal. The specific implementation of the real-time updating of the second direction can be referenced to the description of the real-time updating of the first direction described above and will not be repeated here.
[0347] In addition, in some embodiments, when the communication mode between the terminal and the first device is: different terminals simultaneously send the first signal in different first directions or different second directions, the first direction or the second direction may not need to be updated in real time. Specifically, when multiple terminals send the first signal in different first directions or different second directions respectively, if the number of terminals is large enough, the combined coverage of the first direction or the second direction of the sufficient number of terminals is large (very likely close to omnidirectional). At this time, since different terminals will send the first signal in different first directions or different second directions at the same time, the first signal sent will cover all the first devices. On this basis, no matter how the first device or the terminal moves, the first signal can be received by all the first devices, so there is no need to update the first direction or the second direction, thus avoiding the additional resource overhead caused by updating the first direction or the second direction.
[0348] Optionally, the above-mentioned directional transmission of the first signal in the first direction or the second direction can be achieved by controlling the beam direction of the first signal transmission beam. For example, the beam direction of the first signal transmission beam can be controlled to the first direction or the second direction to achieve directional transmission in the first direction or the second direction.
[0349] It should be noted that, in some embodiments, the above-mentioned first transmission mode may be transparent to the first device, that is, for the first device, the network device will not configure the first transmission mode to the first device, and the first device will not determine the first transmission mode of the first signal. The first device cannot know the first transmission mode. At this time, the first device only passively receives (for example, blindly detects) the first signal. Optionally, in other embodiments, the above-mentioned first transmission mode may be non-transparent to the first device, that is, the network device will configure the first transmission mode to the first device, or the first device will determine the first transmission mode based on the protocol pre-definition. At this time, the first device can know the first transmission mode of the first signal, and the first device can determine the transmission direction of the first signal (that is, the above-mentioned omnidirectional, first direction, or second direction) based on the first transmission mode. If the transmission direction of the first signal covers the first device, the first device monitors and receives the first signal. Otherwise, the first device does not monitor the first signal.
[0350] Furthermore, in some embodiments, when a terminal transmits a first signal, in addition to transmitting the first signal based on a first transmission mode, the terminal may also transmit the first signal based on a first transmission parameter. Optionally, the terminal may determine the first transmission parameter corresponding to the first signal based on protocol pre-definition and / or network device configuration. The first transmission parameter may be used to implement transmission of the first signal; for example, the first transmission parameter may be a time-frequency resource for the first signal. Furthermore, the terminal may transmit the first signal based on the first transmission mode and the first transmission parameter.
[0351] Optionally, in some embodiments, with respect to the aforementioned first transmission parameter, the first transmission parameter corresponding to different terminals covering the same first device in the first direction is the same, and the first transmission parameter corresponding to different terminals covering the same first device group in the second direction is the same. That is, when N terminals cover the same first device in the first direction or the second direction, the first transmission parameters corresponding to the N terminals are the same, where N is a positive integer greater than 1.
[0352] It should be noted that the embodiments of the present disclosure are only introduced by taking the communication between the terminal and the first device as an example. In other embodiments, the network device can also communicate with the first device. For example, the network device can send a first signal, a second signal, and a third signal to the first device, and the first device can send a fourth signal to the network device. The communication method between the network device and the first device is similar to the communication method between the terminal and the first device, and will not be repeated here.
[0353] In the above embodiment, the terminal will determine at least one of the first transmission mode, the second transmission mode, the receiving mode, and the third transmission mode, wherein the first transmission mode is: the transmission mode when the terminal sends a first signal to the first device; the first device is used to collect energy and communicate based on the collected energy; the first signal is used to charge the first device; the second transmission mode is: the transmission mode when the terminal sends a second signal to the first device; the second signal is used to stimulate the first device to achieve backscatter communication; the third transmission mode is: the transmission mode when the terminal sends a third signal to the first device; the third signal is used to carry information sent by the terminal to the first device; the receiving mode is: the transmission mode when the terminal receives a fourth signal sent by the first device; the fourth signal is used to carry information sent by the first device. Therefore, it can be seen that the embodiment of the present disclosure provides a method for a terminal to determine at least one of the first transmission mode, the second transmission mode, the receiving mode, and the third transmission mode, so that the terminal successfully determines at least one of the first transmission mode, the second transmission mode, the receiving mode, and the third transmission mode, so that the terminal can subsequently communicate with the first device based on at least one of the first transmission mode, the second transmission mode, the receiving mode, and the third transmission mode, thereby achieving successful communication between the terminal and the first device and ensuring efficient transmission between the terminal and the first device.
[0354] The communication method involved in the embodiments of the present disclosure may include at least one of steps 2101 to 2103. For example, step 2101 may be implemented as an independent embodiment, step 2102 may be implemented as an independent embodiment, step 2103 may be implemented as an independent embodiment, and step 2101+S2102 may be implemented as an independent embodiment, but the present invention is not limited thereto.
[0355] In this embodiment or example, unless there is any contradiction, each step can be independent, arbitrarily combined or exchanged in order, the optional methods or optional examples can be arbitrarily combined, and can be arbitrarily combined with any steps of other embodiments or other examples.

[0357] Step 2201: The network device configures the second sending mode.
[0358] Optionally, the network device may configure the second transmission mode for the terminal; the terminal may receive the second transmission mode configured by the network device. Optionally, in some embodiments, the network device may configure the second transmission mode via high-layer signaling, such as RRC signaling.
[0359] Optionally, the second transmission mode described above may be a transmission mode in which the terminal sends a second signal to the first device; optionally, the second signal may be used to stimulate the first device to implement backscatter communication, and the second signal may be a continuous constant-amplitude wave (a constant-amplitude sine wave), for example, the second signal may be the aforementioned CW signal. For a detailed description of the CW signal, please refer to the previous description of the embodiment of FIG. 2A and will not be repeated here.
[0360] It should be noted that, in some embodiments, the first signal and the second signal may be the same signal, in which case the signal may simultaneously achieve the functions of charging and excitation; or, in other embodiments, the first signal and the second signal may be different signals.
[0361] Optionally, in some embodiments, the second sending mode may be omnidirectional sending, where “omnidirectional sending” may be understood as sending the second signal in all directions.
[0362] Alternatively, in other embodiments, the second transmission mode may be directional transmission in a third direction, wherein the third direction may cover part or all of the first device. Alternatively, in some embodiments, the third directions configured by the network device to different terminals may be the same or different. Furthermore, when the third direction covers part of the first device, the third directions of different terminals may or may not cover the same first device repeatedly.
[0363] Optionally, in some further embodiments, the second transmission mode may be: directional transmission in a fourth direction; wherein the fourth direction may cover at least one first device group, wherein the first device group may include at least one first device, and different first device groups may include different or partially identical first devices.

[0366] For a detailed description of the second sending method, please refer to the above embodiment description.
[0367] Step 2203: The terminal sends a second signal based on the second sending mode.
[0368] Optionally, when the second sending mode is different, the execution process of step 2203 will also be different.
[0369] Specifically, in some embodiments, when the second transmission mode is "omnidirectional transmission," the terminal may transmit the second signal in all directions based on the second transmission mode. In this case, the second signal transmitted by the terminal can be received by all first devices. Furthermore, in some embodiments, when multiple terminals want to communicate with the first device, the multiple terminals may simultaneously transmit the second signal omnidirectionally. In this case, the second signals transmitted by the multiple terminals can be received by all first devices, thereby improving the terminal charging performance.
[0370] Optionally, in other embodiments, when the second transmission mode is "directional transmission in a third direction," when the terminal transmits the second signal based on the second transmission mode, the second signal may be directionally transmitted only in the third direction, and not in any other directions except the third direction. Optionally, the third direction may cover part or all of the first device. When the third direction covers part of the first device, the second signal directionally transmitted by the terminal in the third direction can only be received by the part of the first device covered by the third direction; when the third direction covers all of the first devices, the second signal directionally transmitted by the terminal in the third direction can be received by all of the first devices. Optionally, in some embodiments, when multiple terminals want to communicate with the first device, the third directions of different terminals may be different or the same, and different terminals may simultaneously transmit the second signal directionally in the third direction. Optionally, when multiple terminals want to communicate with the first device and the third direction covers part of the first device, the third directions of different terminals may overlap with the same first device or not overlap with the same first device. When the third directions of different terminals overlap with the same first device, the overlapped first device can simultaneously receive the second signals sent by different terminals. In addition, when the third directions of different terminals do not repeatedly cover the same first device, when a sufficient number of terminals send the second signal simultaneously in the third direction, all first devices can receive the second signal, thereby achieving full coverage of the second signal for the first devices. When the first device performs backscatter communication based on the second signal, the performance of the backscatter communication can be ensured.
[0371] Optionally, in some further embodiments, when the second transmission mode is "directional transmission in the fourth direction," when the terminal transmits the second signal based on the second transmission mode, the terminal may transmit the second signal directionally only in the fourth direction, and not transmit the second signal in directions other than the fourth direction. Optionally, the fourth direction may cover at least one first device group, wherein the second signal directionally transmitted by the terminal in the fourth direction may be received by the first device in the at least one first device group covered by the fourth direction. Optionally, in some embodiments, when multiple terminals want to communicate with the first device, the fourth directions of different terminals may be different or the same, and different terminals may simultaneously transmit the second signal directionally in the fourth direction. Furthermore, the fourth directions of different terminals may overlap or not overlap the same first device group. When the fourth directions of different terminals overlap the same first device group, the first devices in the overlapped first device group may simultaneously receive the second signals respectively transmitted by the different terminals. In addition, when the fourth directions of different terminals do not repeatedly cover the same group of first devices, when a sufficient number of terminals send the second signal simultaneously in the fourth direction, all first devices can receive the second signal, thereby achieving full coverage of the second signal for the first devices. When the first device performs backscatter communication based on the second signal, the performance of the backscatter communication can be ensured.
[0372] Furthermore, in some embodiments, since the above-mentioned terminal and / or first device usually moves, the relative direction between the terminal and the first device will change. At this time, in order to ensure that the second signal can be accurately sent to the corresponding first device, it is usually necessary to update the third direction or fourth direction when sending the second signal in real time, so that the third direction or fourth direction can track and cover the moving first device in real time.
[0373] Specifically, in some embodiments, the above-mentioned real-time update method of the third direction can be: the terminal tracks in real time the direction change of the first device to be covered by the transmission of the terminal's second signal relative to the terminal. For example, the terminal can obtain the real-time position of the first device from the network device and / or the first device, and determine the direction change of the first device to be covered relative to the terminal (or terminal antenna) based on the real-time position of the first device and the real-time position of the terminal. After that, the terminal can update the third direction in real time based on the direction change of the first device to be covered relative to the terminal, so that the third direction can cover the first device to be covered in real time.
[0374] Optionally, the fourth direction real-time update method may include: the terminal tracking, in real time, changes in the direction of the first device in the first device group required for coverage of the terminal's second signal relative to the terminal, and updating the fourth direction in real time based on the changes in the direction of the first device in the first device group required for coverage relative to the terminal. The specific implementation of the fourth direction real-time update can be found in the description of the third direction real-time update described above and will not be repeated here.
[0375] In addition, in some embodiments, when the communication mode between the terminal and the first device is: different terminals simultaneously send the second signal in different third directions or different fourth directions, the third direction or fourth direction may not need to be updated in real time. Specifically, when multiple terminals send the second signal in different third directions or different fourth directions respectively, if the number of terminals is large enough, the range covered by the third direction or fourth direction of the sufficient number of terminals is large (very likely close to omnidirectional). At this time, since different terminals will send the second signal in different third directions or different fourth directions at the same time, the second signal sent will be able to cover all first devices. On this basis, no matter how the first device or terminal moves, the second signal can be received by all first devices, so there is no need to update the third direction or fourth direction, thus avoiding the additional resource overhead caused by updating the third direction or fourth direction.
[0376] Optionally, the above-mentioned directional transmission of the second signal in the third direction or the fourth direction can be achieved by controlling the beam direction of the second signal transmission beam. For example, the beam direction of the second signal transmission beam can be controlled to the third direction or the fourth direction to achieve directional transmission in the third direction or the fourth direction.
[0377] It should be noted that, in some embodiments, the above-mentioned second transmission mode may be transparent to the first device, that is, for the first device, the network device will not configure the second transmission mode to the first device, and the first device will not determine the second transmission mode of the second signal. The first device cannot know the second transmission mode. At this time, the first device only passively receives (for example, blindly detects) the second signal. Optionally, in other embodiments, the above-mentioned second transmission mode may be non-transparent to the first device, that is, the network device will configure the second transmission mode to the first device, or the first device will determine the second transmission mode based on the protocol pre-definition. At this time, the first device can know the second transmission mode of the second signal, and the first device can determine the transmission direction of the second signal based on the second transmission mode (that is, the above-mentioned omnidirectional, third direction, or fourth direction). If the transmission direction of the second signal covers the first device, the first device monitors and receives the second signal. Otherwise, the first device does not monitor the second signal.
[0378] Furthermore, in some embodiments, when transmitting a second signal, the terminal may, in addition to transmitting the second signal based on the second transmission mode, also transmit the second signal based on a second transmission parameter. Optionally, the terminal may determine the second transmission parameter corresponding to the second signal based on protocol pre-definition and / or network device configuration. The second transmission parameter may be used to implement transmission of the second signal; the second transmission parameter may, for example, be the time-frequency resource of the second signal. Furthermore, the terminal may transmit the second signal based on the second transmission mode and the second transmission parameter.
[0379] Optionally, in some embodiments, with respect to the second transmission parameter, different terminals covering the same first device in the third direction have the same corresponding second transmission parameter, and different terminals covering the same first device group in the fourth direction have the same corresponding second transmission parameter. That is, when N terminals cover the same first device in the third direction or the fourth direction, the second transmission parameters corresponding to the N terminals are the same, where N is a positive integer greater than 1.
[0380] In the above embodiment, the terminal will determine at least one of the second transmission mode, the second transmission mode, the receiving mode, and the third transmission mode, wherein the second transmission mode is: the transmission mode when the terminal sends the first signal to the first device; the first device is used to collect energy and communicate based on the collected energy; the first signal is used to charge the first device; the second transmission mode is: the transmission mode when the terminal sends the second signal to the first device; the second signal is used to stimulate the first device to achieve backscatter communication; the third transmission mode is: the transmission mode when the terminal sends the third signal to the first device; the third signal is used to carry information sent by the terminal to the first device; the receiving mode is: the transmission mode when the terminal receives the fourth signal sent by the first device; the fourth signal is used to carry information sent by the first device. Therefore, it can be seen that the embodiment of the present disclosure provides a method for a terminal to determine at least one of the second transmission mode, the second transmission mode, the receiving mode, and the third transmission mode, so that the terminal successfully determines at least one of the second transmission mode, the second transmission mode, the receiving mode, and the third transmission mode, so that the terminal can subsequently communicate with the first device based on at least one of the second transmission mode, the second transmission mode, the receiving mode, and the third transmission mode, thereby achieving successful communication between the terminal and the first device and ensuring efficient transmission between the terminal and the first device.
[0381] The communication method involved in the embodiments of the present disclosure may include at least one of steps 2201 to 2203. For example, step 2201 may be implemented as an independent embodiment, step 2202 may be implemented as an independent embodiment, step 2203 may be implemented as an independent embodiment, and step 2201+S2202 may be implemented as an independent embodiment, but the present invention is not limited thereto.
[0382] In this embodiment or example, unless there is any contradiction, each step can be independent, arbitrarily combined or exchanged in order, the optional methods or optional examples can be arbitrarily combined, and can be arbitrarily combined with any steps of other embodiments or other examples.
[0383] FIG2C is an interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG2C , the embodiment of the present disclosure relates to a communication method for use in a communication system 100, the method comprising:
[0384] Step 2301: The network device configures a receiving mode.
[0385] Optionally, the network device may configure the receiving mode for the terminal; the terminal may receive the receiving mode configured by the network device. Optionally, in some embodiments, the network device may configure the receiving mode via high-layer signaling, such as RRC signaling.
[0386] Optionally, the aforementioned receiving mode may be: a receiving mode when the terminal receives a fourth signal sent by the first device; optionally, the fourth signal may be used to carry information sent by the first device, and the fourth signal may be, for example, the aforementioned UR signal. For a detailed description of the UR signal, please refer to the description before the embodiment of FIG. 2A and will not be repeated here.
[0387] Optionally, in some embodiments, the fourth signal may be a signal obtained by the first device after backscattering based on the second signal (for an introduction to the second signal, refer to the above embodiment), or the fourth signal may be a signal actively transmitted by the first device based on its stored energy.
[0388] Optionally, in some embodiments, the receiving mode may be omnidirectional receiving, where “omnidirectional receiving” may be understood as receiving the fourth signal in all directions, for example.
[0389] Alternatively, in other embodiments, the receiving mode may be directional reception in a fifth direction, wherein the fifth direction may cover part or all of the first device. Alternatively, in some embodiments, the fifth directions configured by the network device for different terminals may be the same or different. Furthermore, when the fifth direction covers part of the first device, the fifth directions of different terminals may or may not cover the same first device.
[0390] Optionally, in some further embodiments, the receiving mode may be: directional reception in a sixth direction; wherein the sixth direction may cover at least one first device group, wherein the first device group may include at least one first device, and different first device groups may include different or partially identical first devices. Optionally, in some embodiments, the network device is configured to transmit different or identical sixth directions to different terminals, and the sixth directions of different terminals may or may not overlap the same first device group.
[0391] Step 2302: The terminal determines the receiving mode.
[0392] Optionally, the terminal may determine the receiving mode based on the configuration of the network device, and / or the terminal may determine the receiving mode based on a protocol pre-definition.
[0393] For a detailed description of the receiving method, please refer to the above embodiment description.
[0394] Step 2303: The terminal receives a fourth signal based on the receiving mode.
[0395] Optionally, when the receiving mode is different, the execution process of step 2303 will also be different.
[0396] Specifically, in some embodiments, when the receiving mode is "omnidirectional reception," the terminal may receive the fourth signal in all directions based on the receiving mode. In this case, the terminal may receive the fourth signal sent by all first devices. Furthermore, in some embodiments, when multiple terminals want to communicate with the first device, the multiple terminals may simultaneously receive the fourth signal omnidirectionally. In this case, the multiple terminals may each receive the fourth signal sent by all first devices, thereby improving terminal charging performance.
[0397] Optionally, in other embodiments, when the receiving mode is "directional reception in the fifth direction", when the terminal receives the fourth signal based on the receiving mode, it may be that the fourth signal is directionally received only in the fifth direction, and the fourth signal is not received in directions other than the fifth direction. Optionally, the fifth direction may cover part or all of the first device, wherein, when the fifth direction covers part of the first device, the terminal can only receive the fourth signal sent by the part of the first device covered by the fifth direction when directionally receiving the fourth signal in the fifth direction; when the fifth direction covers all the first devices, the terminal can receive the fourth signal sent by all the first devices when directionally receiving the fourth signal in the fifth direction. Optionally, in some embodiments, when there are multiple terminals to communicate with the first device, the fifth directions of different terminals may be different or the same, and different terminals may simultaneously receive the fourth signal directionally in the fifth direction. Optionally, when there are multiple terminals that want to communicate with the first device and the fifth direction covers part of the first device, the fifth directions of different terminals may repeatedly cover the same first device or not repeatedly cover the same first device, wherein, when the fifth directions of different terminals repeatedly cover the same first device, for the repeatedly covered first device, the fourth signal sent by it can be received by different terminals at the same time. And, when the fifth directions of different terminals do not repeatedly cover the same first device, when a sufficient number of terminals respectively receive the fourth signal in the fifth direction, multiple terminals can receive the fourth signal sent by all first devices, achieving full coverage reception of the fourth signal sent by the first device. Then, when the terminal communicates with the first device based on the fourth signal, the transmission performance between the terminal and the first device can be ensured.
[0398] Optionally, in some further embodiments, when the receiving mode is "directional reception in the sixth direction," the terminal may directionally receive the fourth signal only in the sixth direction based on the receiving mode, and not receive the fourth signal in directions other than the sixth direction. Optionally, the sixth direction may cover at least one first device group, wherein the fourth signal directionally received by the terminal in the sixth direction may be the fourth signal transmitted by a first device in the at least one first device group covered by the sixth direction. Optionally, in some embodiments, when multiple terminals want to communicate with the first device, the sixth directions of different terminals may be different or the same, and different terminals may simultaneously receive the fourth signal directionally in the sixth direction. Furthermore, the sixth directions of different terminals may overlap or not overlap the same first device group. When the sixth directions of different terminals overlap the same first device group, the fourth signal transmitted by the first device in the overlapped first device group can be received simultaneously by different terminals. In addition, when the sixth direction of different terminals does not repeatedly cover the same group of first devices, when a sufficient number of terminals receive the fourth signal in the sixth direction respectively, multiple terminals can receive the fourth signals sent by all first devices, thereby achieving full coverage reception of the fourth signal sent by the first device. When the terminal communicates with the first device based on the fourth signal, the transmission performance between the terminal and the first device can be ensured.
[0399] Furthermore, in some embodiments, since the above-mentioned terminal and / or first device usually moves, the relative direction between the terminal and the first device will change. At this time, in order to ensure that the terminal can accurately receive the fourth signal sent by the first device, it is usually necessary to update the fifth direction or sixth direction when receiving the fourth signal in real time, so that the fifth direction or sixth direction can track and cover the moving first device in real time.
[0400] Specifically, in some embodiments, the above-mentioned fifth direction real-time update method can be: the terminal tracks in real time the direction change of the first device required to be covered by the terminal's reception of the fourth signal relative to the terminal. For example, the terminal can obtain the real-time position of the first device from the network device and / or the first device, and determine the direction change of the first device required to be covered relative to the terminal (or terminal antenna) based on the real-time position of the first device and the real-time position of the terminal. After that, the terminal can update the fifth direction in real time based on the direction change of the first device required to be covered relative to the terminal, so that the fifth direction can cover the first device required to be covered in real time.
[0401] Optionally, the aforementioned sixth direction real-time update method may include: the terminal tracking, in real time, changes in the direction of a first device in the first device group required for coverage of the terminal's reception of the fourth signal relative to the terminal, and updating the sixth direction in real time based on the changes in the direction of the first device in the first device group required for coverage relative to the terminal. The specific implementation of the sixth direction real-time update can be referenced to the description of the fifth direction real-time update described above and will not be repeated here.
[0402] In addition, in some embodiments, when the communication mode between the terminal and the first device is: different terminals simultaneously receive the fourth signal in different fifth directions or different sixth directions, the fifth direction or the sixth direction may not need to be updated in real time. Specifically, when multiple terminals receive the fourth signal in different fifth directions or different sixth directions respectively, if the number of terminals is large enough, the range covered by the fifth direction or the sixth direction of the sufficient number of terminals is large (very likely close to omnidirectional). At this time, since different terminals will simultaneously receive the fourth signal sent by the first device in different fifth directions or different sixth directions, the fourth signal sent by the first device will be able to cover all terminals. On this basis, no matter how the first device or the terminal moves, the terminal will receive the fourth signal sent by all first devices, so there is no need to update the fifth direction or the sixth direction, thereby avoiding the additional resource overhead caused by updating the fifth direction or the sixth direction.
[0403] Optionally, the above-mentioned directional reception of the fourth signal in the fifth direction or the sixth direction can be achieved by controlling the beam direction of the fourth signal receiving beam. For example, the beam direction of the fourth signal receiving beam can be controlled to the fifth direction or the sixth direction to achieve directional reception in the fifth direction or the sixth direction.
[0404] Furthermore, in some embodiments, when receiving the fourth signal, the terminal may receive the fourth signal based on reception parameters in addition to the reception mode. Optionally, the terminal may determine the reception parameters corresponding to the fourth signal based on protocol pre-definition and / or network device configuration. The reception parameters may be used to implement reception of the fourth signal. The reception parameters may, for example, include the time-frequency resources of the fourth signal and / or the specific content of the information sent by the first device and carried on the fourth signal. Furthermore, the terminal may receive the fourth signal based on the reception mode and the reception parameters.
[0405] Optionally, in some embodiments, with respect to the aforementioned reception parameters, the reception parameters corresponding to different terminals covering the same first device in the fifth direction are the same, and the reception parameters corresponding to different terminals covering the same first device group in the sixth direction are the same. That is, when the fifth direction or the sixth direction of N terminals covers the same first device, the reception parameters corresponding to the N terminals are the same, where N is a positive integer greater than 1.
[0406] Step 2304: If the receiving direction of the terminal overlaps with the receiving direction of another terminal, the first processing is performed.
[0407] Optionally, the above-mentioned other terminals can be any terminal other than this terminal, and the above-mentioned "the receiving direction of the terminal overlaps with the receiving direction of other terminals" can include, for example: the receiving mode of the terminal and other terminals is omnidirectional reception, or the first device covered by the fifth direction of the terminal is repeated with the first device covered by the fifth direction of at least one other terminal, or the first device group covered by the sixth direction of the terminal is repeated with the first device group covered by the sixth direction of at least one other terminal.
[0408] Optionally, the above-mentioned first processing may be used to combine the fourth signal received by the terminal with the fourth signals received by other terminals to ensure the integrity of the fourth signal.
[0409] Optionally, in some embodiments, the first processing may be to merge the fourth signal received by the terminal and the fourth signal received by other terminals into a second device, where the second device may be, for example, a network device, a terminal, or any other terminal. When the second device is different, the first processing performed is also different. Optionally, when the second device is a network device, it means that the fourth signal received by the terminal and the fourth signal received by other terminals are merged into the network device at this time, and the first processing may include: the terminal sending the fourth signal received from the first device to the network device; when the second device is a terminal, it means that the fourth signal received by the terminal and the fourth signal received by other terminals are merged into the terminal at this time, and the first processing may include: the terminal receiving the fourth signal sent by the other terminal, wherein the fourth signal sent by the other terminal is the fourth signal received by the other terminal from the first device; when the second device is the other terminal, it means that the fourth signal received by the terminal and the fourth signal received by other terminals are merged into the other terminal at this time, and the first processing may include: the terminal sending the fourth signal received from the first device to the other terminal.
[0410] In the above embodiment, the terminal will determine at least one of the first transmission mode, the second transmission mode, the receiving mode, and the third transmission mode, wherein the first transmission mode is: the transmission mode when the terminal sends a first signal to the first device; the first device is used to collect energy and communicate based on the collected energy; the first signal is used to charge the first device; the second transmission mode is: the transmission mode when the terminal sends a second signal to the first device; the second signal is used to stimulate the first device to achieve backscatter communication; the third transmission mode is: the transmission mode when the terminal sends a third signal to the first device; the third signal is used to carry information sent by the terminal to the first device; the receiving mode is: the transmission mode when the terminal receives a fourth signal sent by the first device; the fourth signal is used to carry information sent by the first device. Therefore, it can be seen that the embodiment of the present disclosure provides a method for a terminal to determine at least one of the first transmission mode, the second transmission mode, the receiving mode, and the third transmission mode, so that the terminal successfully determines at least one of the first transmission mode, the second transmission mode, the receiving mode, and the third transmission mode, so that the terminal can subsequently communicate with the first device based on at least one of the first transmission mode, the second transmission mode, the receiving mode, and the third transmission mode, thereby achieving successful communication between the terminal and the first device and ensuring efficient transmission between the terminal and the first device.
[0411] The communication method according to the embodiments of the present disclosure may include at least one of steps 2301 to 2303. For example, step 2301 may be implemented as an independent embodiment, step 2302 may be implemented as an independent embodiment, step 2303 may be implemented as an independent embodiment, and step 2301+step 2302 may be implemented as an independent embodiment, but the present invention is not limited thereto.
[0412] In this embodiment or example, unless there is any contradiction, each step can be independent, arbitrarily combined or exchanged in order, the optional methods or optional examples can be arbitrarily combined, and can be arbitrarily combined with any steps of other embodiments or other examples.
[0413] FIG2D is an interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG2D , the embodiment of the present disclosure relates to a communication method for use in a communication system 100, the method comprising:
[0414] Step 2401: The network device configures the third sending mode.
[0415] Optionally, the network device may configure the third transmission mode for the terminal; the terminal may receive the third transmission mode configured by the network device. Optionally, in some embodiments, the network device may configure the third transmission mode via high-layer signaling, such as RRC signaling.
[0416] Optionally, the third transmission mode may be a transmission mode in which the terminal sends a third signal to the first device. Optionally, the third signal may be used to carry information sent by the terminal to the first device. The third signal may be, for example, the aforementioned DT signal. For a detailed description of the DT signal, please refer to the previous description of the embodiment of FIG. 2A and will not be repeated here.
[0417] Optionally, in some embodiments, the third sending mode may be omnidirectional sending, where “omnidirectional sending” may be understood as sending the third signal in all directions.
[0418] Optionally, in other embodiments, the third transmission mode may be: directional transmission in a seventh direction; wherein the seventh direction may cover part or all of the first device. Optionally, in some embodiments, the seventh directions configured by the network device to different terminals may be the same or different. Furthermore, when the seventh direction covers part of the first device, the seventh directions of different terminals may or may not repeatedly cover the same first device.
[0419] Optionally, in some further embodiments, the third transmission mode may be: directional transmission in an eighth direction; wherein the eighth direction may cover at least one first device group, wherein the first device group may include at least one first device, and different first device groups may include different or partially identical first devices. Optionally, in some embodiments, the eighth directions configured by the network device to different terminals may be different or the same, and the eighth directions of different terminals may or may not repeatedly cover the same first device group.
[0420] Step 2402: The terminal determines the third sending method.
[0421] Optionally, the terminal may determine the third sending mode based on the configuration of the network device, and / or the terminal may determine the third sending mode based on protocol predefinition.
[0422] For a detailed description of the third sending method, please refer to the above embodiment description.
[0423] Step 2403: The terminal sends a third signal based on the third sending mode.
[0424] Optionally, when the third sending mode is different, the execution process of step 2403 will also be different.
[0425] Specifically, in some embodiments, when the third transmission mode is "omnidirectional transmission," the terminal may transmit the third signal in all directions based on the third transmission mode. In this case, the third signal transmitted by the terminal can be received by all first devices. Furthermore, in some embodiments, when multiple terminals want to communicate with the first device, the multiple terminals may simultaneously transmit the third signal omnidirectionally. In this case, the third signals transmitted by the multiple terminals can be received by all first devices, thereby improving the charging performance of the terminals.
[0426] Optionally, in other embodiments, when the third transmission mode is "directional transmission in the seventh direction," when the terminal transmits the third signal based on the third transmission mode, the terminal may transmit the third signal directionally only in the seventh direction, and not in any other directions except the seventh direction. Optionally, the seventh direction may cover part or all of the first device. When the seventh direction covers part of the first device, the third signal directionally transmitted by the terminal in the seventh direction can only be received by the part of the first device covered by the seventh direction; when the seventh direction covers all of the first devices, the third signal directionally transmitted by the terminal in the seventh direction can be received by all of the first devices. Optionally, in some embodiments, when multiple terminals want to communicate with the first device, the seventh directions of different terminals may be different or the same, and different terminals may simultaneously transmit the third signal directionally in the seventh direction. Optionally, when multiple terminals want to communicate with the first device and the seventh direction covers part of the first device, the seventh directions of different terminals may overlap with the same first device or may not overlap with the same first device. When the seventh directions of different terminals overlap with the same first device, the overlapped first device can simultaneously receive the third signals transmitted by different terminals. In addition, when the seventh direction of different terminals does not repeatedly cover the same first device, when the third signal is sent in the seventh direction by a sufficient number of terminals respectively, all first devices can receive the third signal, thereby achieving full coverage of the third signal for the first device. When the terminal communicates with the first device based on the third signal, the transmission performance between the terminal and the first device can be ensured.
[0427] Optionally, in some further embodiments, when the third transmission mode is "directional transmission in the eighth direction," when the terminal transmits the third signal based on the third transmission mode, the terminal may directionally transmit the third signal only in the eighth direction, and not transmit the third signal in any direction other than the eighth direction. Optionally, the eighth direction may cover at least one first device group, wherein the third signal directionally transmitted by the terminal in the eighth direction may be received by the first device in the at least one first device group covered by the eighth direction. Optionally, in some embodiments, when multiple terminals want to communicate with the first device, the eighth directions of different terminals may be different or the same, and different terminals may simultaneously transmit the third signal directionally in the eighth direction. Furthermore, the eighth directions of different terminals may overlap or not overlap the same first device group. When the eighth directions of different terminals overlap the same first device group, the first devices in the overlapped first device group may simultaneously receive the third signals transmitted by different terminals. In addition, when the eighth direction of different terminals does not repeatedly cover the same group of first devices, when the third signal is sent in the eighth direction by a sufficient number of terminals respectively, all first devices can receive the third signal, thereby achieving full coverage of the third signal for the first devices. When the terminal communicates with the first device based on the third signal, the transmission performance between the terminal and the first device can be ensured.
[0428] Furthermore, in some embodiments, since the above-mentioned terminal and / or first device usually moves, the relative direction between the terminal and the first device will change. At this time, in order to ensure that the third signal can be accurately sent to the corresponding first device, it is usually necessary to update the seventh direction or the eighth direction when sending the third signal in real time, so that the seventh direction or the eighth direction can track and cover the moving first device in real time.
[0429] Specifically, in some embodiments, the above-mentioned real-time update method of the seventh direction can be: the terminal tracks in real time the direction change of the first device to be covered by the transmission of the terminal's third signal relative to the terminal. For example, the terminal can obtain the real-time position of the first device from the network device and / or the first device, and determine the direction change of the first device to be covered relative to the terminal (or terminal antenna) based on the real-time position of the first device and the real-time position of the terminal. After that, the terminal can update the seventh direction in real time based on the direction change of the first device to be covered relative to the terminal, so that the seventh direction can cover the first device to be covered in real time.
[0430] Optionally, the eighth direction real-time update method may be: the terminal tracks in real time the direction changes of the first device in the first device group required to be covered by the terminal's transmission of the third signal relative to the terminal, and updates the eighth direction in real time based on the direction changes of the first device in the first device group required to be covered relative to the terminal. The specific implementation of the eighth direction real-time update can be found in the description of the seventh direction real-time update described above and will not be repeated here.
[0431] In addition, in some embodiments, when the communication mode between the terminal and the first device is: different terminals simultaneously send the third signal in different seventh directions or different eighth directions, the seventh direction or the eighth direction may not need to be updated in real time. Specifically, when multiple terminals send the third signal in different seventh directions or different eighth directions respectively, if the number of terminals is large enough, the range covered by the seventh direction or the eighth direction of the sufficient number of terminals is large (very likely close to omnidirectional). At this time, since different terminals will send the third signal in different seventh directions or different eighth directions at the same time, the third signal sent will be able to cover all first devices. On this basis, no matter how the first device or terminal moves, the third signal can be received by all first devices, so there is no need to update the seventh direction or the eighth direction, thus avoiding the additional resource overhead caused by updating the seventh direction or the eighth direction.
[0432] Optionally, the above-mentioned directional transmission of the third signal in the seventh direction or the eighth direction can be achieved by controlling the beam direction of the third signal transmission beam. For example, the beam direction of the third signal transmission beam can be controlled to the seventh direction or the eighth direction to achieve directional transmission in the seventh direction or the eighth direction.
[0433] It should be noted that, in some embodiments, the third transmission mode mentioned above can be transparent to the first device, that is, for the first device, the network device will not configure the third transmission mode to the first device, and the first device will not determine the third transmission mode of the third signal. The first device cannot know the third transmission mode. At this time, the first device only passively receives (for example, blindly detects) the third signal. Optionally, in other embodiments, the third transmission mode mentioned above can be non-transparent to the first device, that is, the network device will configure the third transmission mode to the first device, or the first device will determine the third transmission mode based on the protocol pre-definition. At this time, the first device can know the third transmission mode of the first signal, and the first device can determine the transmission direction of the third signal based on the third transmission mode (that is, the above-mentioned omnidirectional, seventh direction, or eighth direction). If the transmission direction of the third signal covers the first device, the first device monitors and receives the third signal. Otherwise, the first device does not monitor the third signal.
[0434] It should be emphasized that in some embodiments, the above-mentioned grouping method of the first device when determining the first sending mode, the grouping method of the first device when determining the second sending mode, the grouping method of the first device when determining the third sending mode, and the grouping method of the first device when determining the receiving mode may be the same or different, so as to improve the flexibility during communication.
[0435] Furthermore, in some embodiments, when transmitting a third signal, the terminal may, in addition to transmitting the third signal based on a third transmission mode, also transmit the third signal based on third transmission parameters. Optionally, the terminal may determine the third transmission parameters corresponding to the third signal based on protocol pre-definition and / or network device configuration. The third transmission parameters may be used to implement the transmission of the third signal. The third transmission parameters may, for example, include the time-frequency resources of the third signal and / or the specific content of the information carried by the terminal to the first device on the third signal. Furthermore, the terminal may transmit the third signal based on the third transmission mode and the third transmission parameters.
[0436] Optionally, in some embodiments, with respect to the third transmission parameter, different terminals covering the same first device in the seventh direction have the same corresponding third transmission parameter, and different terminals covering the same first device group in the eighth direction have the same corresponding third transmission parameter. That is, when the seventh direction or the eighth direction of N terminals covers the same first device, the third transmission parameters corresponding to the N terminals are the same, where N is a positive integer greater than 1.
[0437] In the above embodiment, the terminal will determine at least one of the first transmission mode, the second transmission mode, the receiving mode, and the third transmission mode, wherein the first transmission mode is: the transmission mode when the terminal sends a first signal to the first device; the first device is used to collect energy and communicate based on the collected energy; the first signal is used to charge the first device; the second transmission mode is: the transmission mode when the terminal sends a second signal to the first device; the second signal is used to stimulate the first device to achieve backscatter communication; the third transmission mode is: the transmission mode when the terminal sends a third signal to the first device; the third signal is used to carry information sent by the terminal to the first device; the receiving mode is: the transmission mode when the terminal receives a fourth signal sent by the first device; the fourth signal is used to carry information sent by the first device. Therefore, it can be seen that the embodiment of the present disclosure provides a method for a terminal to determine at least one of the first transmission mode, the second transmission mode, the receiving mode, and the third transmission mode, so that the terminal successfully determines at least one of the first transmission mode, the second transmission mode, the receiving mode, and the third transmission mode, so that the terminal can subsequently communicate with the first device based on at least one of the first transmission mode, the second transmission mode, the receiving mode, and the third transmission mode, thereby achieving successful communication between the terminal and the first device and ensuring efficient transmission between the terminal and the first device.

[0601] The optional implementation of steps 5501 to 5503 can be found in the above embodiment.
[0602] In some embodiments, the above method may include the method described in the above embodiments of the communication system side, terminal side, network device side, etc., which will not be repeated here.
[0603] The communication method involved in the embodiment of the present disclosure may include at least one of steps 5501 to 5504. For example, step 5501 may be implemented as an independent embodiment, and step 5502 may be implemented as an independent embodiment, but the present invention is not limited thereto.
[0604] In this embodiment or example, unless there is any contradiction, each step can be independent, arbitrarily combined or exchanged in order, the optional methods or optional examples can be arbitrarily combined, and can be arbitrarily combined with any steps of other embodiments or other examples.
[0605] The following is an exemplary introduction to the above method.
[0606] To further conserve power and reduce device complexity, a notable feature of new IoT devices is the ability to harvest energy from the environment and use it for communication. These new devices are referred to as A-IoT devices. A-IoT devices have broad application prospects, including equipment identification and sensors in warehouses, eliminating the need for battery configuration and replacement costs.
[0607] A-IoT devices can be divided into three categories. Type A devices do not support energy storage or only support a small amount of energy storage, and work based on backscatter. They have the lowest complexity and very low power consumption. For example, Type A devices need to receive wireless signals to obtain energy to activate the internal receiving and processing modules. Type B devices support energy storage and work based on backscatter. Their complexity and power consumption are higher than Type A devices, but still maintain a relatively low level. The energy that Type B devices can store is still relatively limited. Type C devices support energy storage and work based on active transmission, that is, Type C devices amplify and transmit information through power amplifiers. Type C devices generally need to store more energy to support active transmission of information
[0608] To support data transmission between A-IoT devices, the network needs to support the following functions. A device in the network can support one or more functions.
[0609] As an excitation (Continuous Wave, CW) function, it is only used for Devices A and B. The A-IoT device implements uplink transmission through backscatter CW.
[0610] As an Energy Source (ES), it can be used for device types B and C. CW is actually a type of ES; A-IoT devices can receive CW and store energy. For device type A, because its supported energy storage capabilities are very limited, ES signals other than CW can be omitted. Alternatively, ES signals can be used for device type A.
[0611] The downlink transmission (DT) function sends indication information to the A-IoT device, thereby triggering the uplink transmission of the A-IoT device.
[0612] The uplink receiving (UR) function receives uplink information backscattered by A-IoT devices, or receives uplink information actively transmitted by A-IoT devices.
[0613] In addition to implementing one or more of the aforementioned functions, the device can also perform uplink and downlink transmissions on the cellular network. Therefore, the network needs to coordinate resource allocation for the aforementioned functions and uplink and downlink transmissions on the cellular network for the device. In particular, a single channel or signal can support both ES and CW functions, requiring resource allocation for only that single channel or signal.
[0614] Example 1
[0615] The ES signal transmitted by a device can be omnidirectional, so the device does not need to track the changes in the position of the A-IoT relative to its antenna in real time. The network can improve the charging performance of A-IoT devices by configuring multiple devices to transmit ES signals simultaneously.
[0616] The ES signal transmitted by a device can be directional, thereby efficiently charging one or more specific A-IoT devices. The device can track the changes in the direction of the A-IoT device relative to its antenna in real time. Alternatively, the network can configure multiple devices to transmit ES signals in different directions and achieve repeated coverage of the A-IoT devices. In this case, although each device cannot quickly track the changes in the direction of the A-IoT device relative to its antenna, the presence of multiple devices transmitting ES signals still ensures that each A-IoT device can always receive the ES signal.
[0617] For A-IoT devices within a certain range, the network can configure a single device to transmit an ES signal to cover all A-IoT devices. Alternatively, the network can configure multiple devices to transmit ES signals, each of which can cover some or all of the A-IoT devices within the range. This approach allows multiple devices to transmit ES signals to charge the same A-IoT device or group of A-IoT devices, increasing the overall ES signal strength and thus improving the performance of charging A-IoT devices.
[0618] For A-IoT devices within a certain range, the network can configure a device to transmit ES signals to cover a group of A-IoT devices within the certain range. For example, by controlling the beam of the ES signal, only the group of A-IoT devices can be charged. The network can cover all A-IoT devices within the certain range by configuring multiple devices to transmit ES signals. For example, the multiple devices use different beams to cover different A-IoT devices within the certain range. By concentrating the ES signal into one beam and using it for a group of A-IoT devices, the efficiency of charging can be improved. Note: The A-IoT devices covered by the above beams may be intersecting. That is, using this method, the network can configure multiple devices to transmit ES signals for charging the same or the same group of A-IoT devices. By configuring the multiple devices to transmit ES signals, the overall strength of the ES signal is increased, thereby improving the performance of charging A-IoT devices.
[0619] The configuration of the ES signal for one or more devices can be transparent to the A-IoT devices. With this approach, when the network configures the ES signal for a device to be used for a group of A-IoT devices, the grouping method for the A-IoT devices can be the same as or different from the grouping method for other CW, UR, or DT functions.
[0620] Example 2
[0621] The CW transmissions from a device can be omnidirectional, eliminating the need for the device to track changes in the A-IoT's position relative to its antenna. Networks can improve the backscatter-based transmission performance of A-IoT devices by configuring multiple devices to transmit CWs simultaneously.
[0622] The CW transmitted by a device can be directional, thereby increasing the strength of the excitation signal to one or more A-IoT devices. The device can track the changes in the orientation of the A-IoT device relative to its antenna in real time. Alternatively, the network can configure multiple devices to transmit CWs in different directions, achieving repeated coverage of the A-IoT devices. In this case, although each device cannot quickly track the changes in the orientation of the A-IoT device relative to its antenna, the presence of multiple devices transmitting CWs still ensures that each A-IoT device can always receive the CW.
[0623] For A-IoT devices within a certain range, the network can configure a single device to transmit a CW to cover all A-IoT devices. Alternatively, the network can configure multiple devices to transmit CWs, each of which can cover some or all of the A-IoT devices within the specified range. This approach allows the network to configure multiple devices to transmit CWs for the same A-IoT device or group of A-IoT devices, increasing the overall CW strength and thus improving the backscatter-based transmission performance for A-IoT devices.
[0624] For A-IoT devices within a certain range, the network can configure a device to transmit CW to cover a group of A-IoT devices within the certain range. For example, by controlling the CW beam, the CW can be transmitted only to the group of A-IoT devices. The network can cover all A-IoT devices within the certain range by configuring multiple devices to transmit CW. For example, the multiple devices use different beams to cover different A-IoT devices within the certain range. By concentrating the CW into one beam and using it for a group of A-IoT devices, the transmission performance of the A-IoT device based on backscattering can be improved. Note: The A-IoT devices covered by the above beams may be intersecting. That is, using this method, the network can configure multiple devices to transmit CW for the same or the same group of A-IoT devices, thereby increasing the overall strength of the CW and thus improving the transmission performance of the A-IoT device based on backscattering.
[0625] The configuration of the CW for one or more devices can be transparent to the A-IoT devices. With this approach, when the network configures a device's CW for a group of A-IoT devices, the grouping method for A-IoT devices can be the same as or different from the grouping method for other ES, UR, or DT functions.
[0626] Example 3
[0627] A device receiving an A-IoT device's uplink transmission can be omnidirectional, eliminating the need for the device to track changes in the A-IoT's position relative to its antenna. The network can improve the performance of A-IoT devices' backscatter-based transmissions by configuring multiple devices to simultaneously receive and combine the A-IoT device's uplink transmissions.
[0628] A device receiving uplink transmissions from an A-IoT device can be directional, thereby improving the performance of receiving uplink transmissions from one or more A-IoT devices. The device can track the changes in the direction of the A-IoT device relative to its antenna in real time. Alternatively, the network can configure multiple devices to receive uplink transmissions from A-IoT devices in a directional manner and achieve repeated coverage of the A-IoT devices. In this case, although each device cannot quickly track the changes in the direction of the A-IoT device relative to its antenna, because there are multiple devices receiving uplink transmissions from A-IoT devices, it is still guaranteed that each A-IoT device uplink transmission can be received.
[0629] For A-IoT devices within a certain range, the network can configure a single device to receive uplink transmissions from all A-IoT devices. Alternatively, the network can configure multiple devices to receive uplink transmissions from A-IoT devices, each of which can cover some or all of the A-IoT devices within the specified range. This approach allows the network to configure multiple devices to receive and combine uplink transmissions from the same A-IoT device or group of A-IoT devices, thereby improving the performance of backscatter-based transmissions to A-IoT devices.
[0630] For A-IoT devices within a certain range, the network can configure a device to receive the uplink transmission of a group of A-IoT devices within the certain range. For example, by controlling the receiving beam of the device, only the uplink transmission of the group of A-IoT devices can be received. The network can cover all A-IoT devices within the certain range by configuring multiple receiving devices. For example, the multiple devices use different beams to cover different A-IoT devices within the certain range. By receiving based on directional beams, the transmission performance of A-IoT devices based on backscattering can be improved. Note: The A-IoT devices covered by the above beams may be intersecting. That is, using this method, the network can configure multiple devices to receive the uplink transmission of the same or the same group of A-IoT devices and merge them, thereby improving the transmission performance of A-IoT devices based on backscattering.
[0631] The configuration of the UR resources for one or more devices can be transparent to the A-IoT devices. With this approach, when the network configures a device to receive uplink URs from a group of A-IoT devices, the grouping method for A-IoT devices can be the same as or different from the grouping method for other ES, CW, or DT functions.
[0632] Example 4
[0633] The DT transmitted by a device can be omnidirectional, so the device does not need to track the changes in the position of the A-IoT relative to its antenna in real time. The network can improve the downlink transmission performance of the A-IoT device by configuring multiple devices to transmit DT simultaneously.
[0634] The DT transmitted by a device can be directional, thereby improving the received signal strength for one or more A-IoT devices. The device can track the changes in the orientation of the A-IoT device relative to its antenna in real time. Alternatively, the network can configure multiple devices to transmit DT in different directions, achieving repeated coverage of the A-IoT devices. In this case, although each device cannot quickly track the changes in the orientation of the A-IoT device relative to its antenna, the presence of multiple devices transmitting DT still ensures that each A-IoT device can always receive downlink information.
[0635] For A-IoT devices within a certain range, the network can configure a single device to transmit DT to cover all A-IoT devices. Alternatively, the network can configure multiple devices to transmit DT, each of which can cover some or all A-IoT devices within the specified range. This approach allows the network to configure multiple device pairs for downlink DT transmissions for the same A-IoT device or group of devices, increasing the received signal strength and thus improving downlink transmission performance for A-IoT devices.
[0636] For A-IoT devices within a certain range, the network can configure a device to transmit DT to cover a group of A-IoT devices within the certain range. For example, by controlling the beam of DT, downlink information can be transmitted only to the group of A-IoT devices. The network can cover all A-IoT devices within the certain range by configuring multiple devices to transmit DT. For example, the multiple devices use different beams to cover different A-IoT devices within the certain range. Note: The A-IoT devices covered by the above beams may be intersecting. By transmitting downlink information to a group of A-IoT devices based on beams, the downlink transmission performance of A-IoT devices can be improved. That is, using this method, the network can configure multiple devices to transmit downlink DT for the same or the same group of A-IoT devices, thereby improving the strength of the received signal and thus improving the downlink transmission performance to the A-IoT devices.
[0637] The configuration of the DT of one or more devices can be transparent to the A-IoT device. With this method, when the network configures multiple devices to send downlink signals to the same or the same group of A-IoT devices, the network needs to distribute the same downlink information and transmission parameters to the multiple devices in a timely manner. With this method, when the network configures a device to transmit downlink information DT to a group of A-IoT devices, the grouping method of the A-IoT devices can be the same as the grouping method of other ES, CW or UR functions, or different.
[0638] By adopting the method disclosed in the present invention, the transmission performance required by A-IoT devices is improved by configuring multiple devices to transmit energy signals or participate in downlink transmission and uplink reception operations of A-IoT devices.
