[0368] Figure 1 is a schematic diagram of the architecture of a communication system according to an embodiment of the present disclosure. As shown in Figure 1, communication system 100 may include a terminal, a network device, and a first device. 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.

Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution proposed in the embodiment of the present disclosure is also applicable to similar technical problems.
[0375] 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.

[0376] 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, systems utilizing other resource determination methods, and next-generation systems based on and extending these systems. Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).
[0377] 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:
[0378] 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.
[0379] The second method is that the terminal sends an Energy Source (ES) signal to the A-IoT device. The ES signal can be used to charge the A-IoT device. Optionally, the A-IoT device can use a higher power to perform backscatter communication based on the energy charged by the ES signal. Alternatively, the A-IoT device can actively transmit based on the energy charged by the ES signal. The active transmission can be understood as: active transmission without CW signal excitation. Among them, the first and second methods mentioned above are specific methods for the A-IoT device to collect energy and communicate based on the collected energy.
[0380] 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.
[0381] 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.
[0382] 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.
[0383] 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.
[0384] 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.
[0385] 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.
[0386] 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.
[0387] 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. When the signals required for communication between a terminal and an A-IoT device include two or more, allocating time-frequency resources for the different signals to ensure successful communication between the terminal and the A-IoT device is a pressing issue.
[0388] FIG2A1 is an interactive diagram of a resource determination method according to an embodiment of the present disclosure. As shown in FIG2A1 , the embodiment of the present disclosure relates to a resource determination method for a communication system 100, the method comprising:
[0389] Step 2101: The network device configures time-frequency resources for at least one of the first signal, the second signal, the third signal, and the fourth signal, and the time-frequency resources of different signals do not overlap in the time domain.
[0390] Optionally, the network device may configure the time-frequency resources of at least one of the first signal, the second signal, the third signal, and the fourth signal to the terminal and / or the first device; the first device and / or the terminal may receive the time-frequency resources configured by the network device. Optionally, in some embodiments, when configuring the time-frequency resources of at least one of the first signal, the second signal, the third signal, and the fourth signal, the network device may configure the time-frequency resources through high-layer signaling, such as Radio Resource Control (RRC) signaling.
[0391] 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). 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 2A1, which will not be repeated here.
[0392] Optionally, the first signal can be used to charge the first device, and the first signal can be, for example, the ES signal described above. The second signal can be used to stimulate the first device to implement backscatter communication, and the second signal can be, for example, the CW signal described above. The third signal can be used to carry information sent by the terminal to the first device, and the third signal can be, for example, the DT signal described above. The fourth signal can be used to carry information sent by the first device, and the fourth signal can be, for example, the UR signal described above. For a detailed introduction to the ES signal, CW signal, DT signal, and UR signal, please refer to the description before the embodiment of Figure 2A1, and will not be repeated here.
[0393] Optionally, in some embodiments, the above-mentioned first signal may be a continuous constant amplitude wave (such as a continuous constant amplitude sine wave), or, in other embodiments, the first signal may not be a continuous constant amplitude wave, but a specific signal carrying information, wherein the information carried by the first signal may be used to distinguish that the current first signal is not a continuous constant amplitude wave, but a specific signal. Optionally, when the first signal is a specific signal carrying information, the terminal may reuse a signal in cellular communication (i.e., communication between the terminal and the network device) as the first signal. For example, the first signal may be a physical uplink shared channel (PUSCH) or a sounding reference signal (SRS). In this case, in addition to realizing its function in cellular communication, the first signal may also be used to charge the first device; or, the first signal may also be an additionally configured or additionally scheduled signal for charging the first device. The present disclosure does not make specific limitations on this.
[0394] It should be noted that, in some embodiments, when the first signal is a specific signal carrying information, the information carried by the first signal can be transparent to the first device, that is, after receiving the first signal carrying information, the first device does not need to parse the information, but only charges based on the first signal. Optionally, in some embodiments, the first signal can also be transparent to the terminal, that is, the terminal will only send the first signal based on the scheduling or configuration of the network device, but the terminal does not know that the first signal it sends can be used to charge the first device.
[0395] Optionally, the second signal may also be a continuous constant amplitude wave (a constant amplitude sine wave).
[0396] 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.
[0397] Optionally, in some embodiments, the fourth signal may be a signal obtained by the first device after backscattering based on the second signal, or the fourth signal may be a signal actively transmitted by the first device based on its stored energy.
[0398] Optionally, the above-mentioned time-frequency resources can be used for communication between the terminal and the first device. For example, the time-frequency resources of the first signal can be used for the terminal to send the first signal, and for the first device to receive the first signal; the time-frequency resources of the second signal can be used for the terminal to send the second signal, and for the first device to receive the second signal; the time-frequency resources of the third signal can be used for the terminal to send the third signal, and for the first device to receive the third signal; the time-frequency resources of the fourth signal can be used for the first device to send the fourth signal, and for the terminal to receive the fourth signal.
[0399] Optionally, the time-frequency resources of the first signal may include at least one of the following:
[0400] Time resource of the first signal;
[0401] frequency resources of the first signal;
[0402] Frequency hopping related parameters of the first signal;
[0403] resources carried by the first signal;
[0404] A beam configuration of the first signal.
[0405] Optionally, the time resource of the above-mentioned first signal may include, for example, at least one of a period, an offset, and the first information. The period may be the transmission period of the first signal, the offset may be the offset of the starting point of the transmission period of the first signal relative to the reference time, and the reference time may be predefined by the protocol and / or determined by the network device. When the reference time is determined by the network device, the network device may also indicate the reference time to the terminal and / or the first device. Optionally, the above-mentioned first information may be used to indicate the duration of the resource used to transmit the first signal in each transmission period of the first signal. Optionally, the duration of the resource may be equal to the period length of the transmission period. In some embodiments, the resource duration may include a continuous resource, or, in other embodiments, the resource duration may be a non-continuous resource. Optionally, the first information may include a bitmap, wherein each bit in the bitmap may correspond to a continuous time domain unit, and the bit value carried by each bit may be used to indicate whether the corresponding time domain unit is used to send the first signal. For example, when the bit value carried by the bit is a first value (such as 0), it may indicate that the corresponding time domain unit is used to send the first signal. When the bit value carried by the bit is a second value (such as 1), it may indicate that the corresponding time domain unit is not used to send the first signal. Optionally, the time domain unit may, for example, include at least one of the following: an orthogonal frequency division multiplexing (OFDM) symbol, a time slot, a subframe, a radio frame, etc.
[0406] Optionally, the frequency resource of the first signal may refer to a frequency domain position of the first signal. Optionally, the frequency resource may include at least one of the following:
[0407] One subcarrier;
[0408] A group of consecutive subcarriers;
[0409] A group of equally spaced subcarriers, i.e., comb subcarriers;
[0410] A physical resource block (PRB);
[0411] A PRB set; the PRB set may include multiple PRBs.
[0412] Optionally, when the frequency resources of the first signal include the above-mentioned comb subcarriers, the comb subcarriers can be mapped to a relatively wide frequency band due to their equally spaced distribution characteristics, thereby combating frequency selective fading. The frequency selective fading can be understood as, for example, different frequencies have different fading at different times. For example, at a certain time point, the fading of frequency #1 may be large, while the fading of frequency #2 is very small. Based on this, in some embodiments, the frequency resources of the first signal are made into comb subcarriers so that the first signal is mapped to a relatively wide frequency band, thereby mapping the first signal to multiple different frequencies. At this time, even if the fading of some frequencies is large, since the first signal maps more frequencies, it will inevitably include frequencies with smaller fading, and it can also ensure that the first signal can be accurately transmitted, thereby combating frequency selective fading.
[0413] Optionally, when the frequency resources of the first signal include the aforementioned PRB set, the PRB set can correspond to the entire bandwidth of the first device transmission, thereby transmitting the first signal over the entire bandwidth of the first device transmission and resisting frequency selective fading. Optionally, the aforementioned "entire bandwidth of the first device transmission" can be understood as, for example, all bandwidth used for transmission (i.e., sending and receiving signals) by the first device.
[0414] Optionally, the above-mentioned frequency hopping related parameters of the first signal may, for example, include a frequency hopping pattern of the first signal, wherein "frequency hopping" may, for example, mean: using different frequency domain resources to send the first signal on different time domain resources, or, it may also mean: using different frequency domain resources to send the first signal on the same time domain resources.
[0415] Optionally, the resources carried by the aforementioned first signal may include, for example, a signal sequence carried by the first signal and / or information carried by the first signal. Optionally, in some embodiments, the first signal may carry a signal sequence, wherein the first signal may be mapped to one or more subcarriers. When the first signal is mapped to multiple subcarriers, each subcarrier may carry a signal sequence to achieve interference averaging. The signal sequence may be predefined based on a protocol, or may be autonomously determined by a network device, or may be randomly generated by the network device. When the signal sequence is randomly generated by a network device, the specific form of the signal sequence may be determined by the capabilities of the network device. Optionally, a detailed description of the information carried by the aforementioned first signal can be found in the preceding content and will not be repeated here. Furthermore, the information carried by the first signal may be predefined by a protocol, or may be autonomously determined by a network device, or may be randomly generated by a network device. When the information is randomly generated by a network device, the specific content of the information may be determined by the capabilities of the network device.
[0416] Optionally, the above-mentioned beam configuration of the first signal can be used to configure the beam for sending the first signal. Optionally, the beam configuration can configure the terminal to send the first signal omnidirectionally, or, the beam configuration can be used to configure which specific beams are used to send the first signal, so that the terminal can send the first signal based on the configured beam.
[0417] Optionally, in some embodiments, the time-frequency resources of the second signal may include at least one of the following:
[0418] Time resource of the second signal;
[0419] frequency resource of the second signal;
[0420] Frequency hopping related parameters of the second signal;
[0421] a sequence resource of a second signal;
[0422] A beam configuration of the second signal.
[0423] Optionally, the time resources of the above-mentioned second signal may include at least one of a period, an offset, a second information, and a timing advance (TA). Optionally, the second information may be used to indicate the duration of the resources used to send the second signal in each sending period of the second signal. For a detailed introduction to the period, offset, and second information, please refer to the aforementioned introduction to the time resources of the first signal. Optionally, the above-mentioned TA may mean that the terminal needs to send the second signal in advance of TA at the configured start time (i.e., the time to start sending the second signal determined by the period, offset, and second information of the second signal), and the second signal within the TA time period may be used to charge and activate the first device. Optionally, in some embodiments, when the first device is an A-IoT device B or an A-IoT device C, since it has an energy storage function, it will store energy, so there is no need to send the second signal in advance to charge and activate it, then TA may be equal to 0 at this time.
[0424] Optionally, the frequency resource of the second signal may refer to a frequency domain position of the second signal. Optionally, the frequency resource may include at least one of the following:
[0425] One subcarrier;
[0426] A group of consecutive subcarriers;
[0427] A group of equally spaced subcarriers, i.e., comb subcarriers;
[0428] Optionally, when the frequency resource of the second signal includes a comb-type subcarrier, the second signal is mapped to multiple subcarriers. In this case, when the first device backscatters the second signal to transmit the fourth signal, the first device may backscatter the second signal on all subcarriers. For further details about the comb-type subcarrier, refer to the above description.
[0429] Optionally, the frequency hopping related parameters of the second signal may refer to the description of the frequency hopping related parameters of the first signal.
[0430] Optionally, the sequence resource of the second signal mentioned above may refer to a signal sequence carried by the second signal. Optionally, in some embodiments, the second signal may carry a signal sequence, wherein the second signal may be mapped to one or more subcarriers. When the second signal is mapped to multiple subcarriers, each subcarrier may carry a signal sequence respectively, and the signals carried on all subcarriers are combined to form a signal sequence carried by the second signal, wherein the signal sequences carried on different subcarriers may be predefined based on a protocol, or may be determined autonomously by a network device, or may be randomly generated by a network device. When the signal sequence is randomly generated by a network device, the specific form of the signal sequence may be determined by the capabilities of the network device.
[0431] Optionally, the beam configuration of the second signal may refer to the aforementioned description of the beam configuration of the first signal.
[0432] Optionally, in some embodiments, the time-frequency resources of the third signal may include at least one of the following:
[0433] Time resources for the third signal;
[0434] frequency resources of the third signal;
[0435] frequency hopping related parameters of the third signal;
[0436] A beam configuration of a third signal.
[0437] For a detailed introduction to the time resources, frequency resources, frequency hopping related parameters, and beam configuration of the third signal, please refer to the description of the time resources, frequency resources, frequency hopping related parameters, and beam configuration of the first signal mentioned above.
[0438] Optionally, in some embodiments, the time-frequency resources of the fourth signal may include at least one of the following:
[0439] Time resources for the fourth signal;
[0440] frequency resources of a fourth signal;
[0441] frequency hopping related parameters of the fourth signal;
[0442] a sequence resource of a fourth signal;
[0443] Beam configuration of the fourth signal.
[0444] Optionally, as can be seen from the foregoing content, the fourth signal can be sent by the first device through backscattering under the stimulation of the second signal. Therefore, for a detailed introduction to the time resources, frequency resources, frequency hopping related parameters, sequence resources, and beam configuration of the fourth signal, reference can be made to the description of the time resources, frequency resources, frequency hopping related parameters, sequence resources, and beam configuration of the above-mentioned second signal.
[0445] It should be emphasized that in some embodiments, when the first device obtains the fourth signal by backscattering the second signal sent by the terminal, the frequency position indicated by the frequency resource of the fourth signal may be the same as the frequency position indicated by the frequency resource of the second signal, or the frequency position indicated by the frequency resource of the fourth signal may have a frequency offset (offset) from the frequency position indicated by the frequency resource of the second signal, and the magnitude of the frequency offset may be related to the hardware characteristics of the first device. Moreover, when the modulation method adopted by the first device is different, the offset method of the fourth signal relative to the second signal will also be different. Optionally, when the modulation method adopted by the first device is a single-sideband modulation method, the fourth signal is offset only in one frequency direction of the second signal. For example, when the first device adopts a single-sideband modulation method, assuming that the frequency position of the second signal is a and the offset corresponding to the first device is b, the frequency position of the fourth signal is: a+b. Optionally, when the modulation mode adopted by the first device is double-sideband modulation, the fourth signal is offset in two frequency directions of the second signal. For example, when the first device adopts double-sideband modulation, assuming that the frequency position of the second signal is a and the offset corresponding to the first device is b, two fourth signals can be obtained by backscattering the second signal, and the frequency positions of the two fourth signals are: a+b and ab, respectively. Based on this, in some embodiments, when the modulation mode of the first device is double-sideband modulation, the terminal can send two single-frequency second signals with relatively large frequency intervals to at least one first device, and each first device can backscatter and modulate information on the two second signals respectively. For each first device, the fourth signal obtained by its backscattering is located on both sides of the second signal, and because the frequency interval of the two second signals is relatively large, the frequency intervals between the multiple fourth signals obtained by backscattering from different first devices are relatively large, thereby obtaining a relatively large frequency diversity gain.
[0446] Optionally, Figure 2A2 is a schematic diagram of multiple fourth signals obtained after at least one first device backscatters two second signals with a relatively large frequency interval according to an embodiment of the present disclosure. As shown in Figure 2A2, the two second signals with a relatively large frequency interval sent by the terminal are respectively: CW1 and CW2. Assuming that there are currently three first devices, namely, first device #1, first device #2, and first device #3, wherein the frequency offset offset corresponding to first device #1 is a, the frequency offset offset corresponding to first device #2 is b, and the frequency offset offset corresponding to first device #3 is c, then the fourth signals obtained after the three first devices backscatter the two second signals with a relatively large frequency interval are CH-1, CH-2, and CH-3 in the figure, wherein CH-1 It is the fourth signal obtained by the first device #1 after backscattering two second signals with farther frequencies. Among them, CH-1 located on both sides of CW1 is the fourth signal obtained by the first device #1 after backscattering CW1, and CH-1 located on both sides of CW2 is the fourth signal obtained by the first device #1 after backscattering CW2. Among them, the frequency offset between CH-1 located on both sides of CW1 and CW1 is the frequency offset offset: a corresponding to the first device #1, and the frequency offset between CH-1 located on both sides of CW2 and CW2 is also the frequency offset offset: a corresponding to the first device #1. Similarly, CH-2 is the fourth signal obtained by the second device #2 after backscattering two second signals with farther frequencies. The CH-2 on either side of CW1 is the fourth signal obtained by the first device #2 after backscattering CW1, and the CH-2 on either side of CW2 is the fourth signal obtained by the second device #2 after backscattering CW2. The frequency offset between CH-2 on either side of CW1 and CW1 is the frequency offset b corresponding to the second device #2, and the frequency offset between CH-2 on either side of CW2 and CW2 is also the frequency offset b corresponding to the second device #2. CH-3 is similar.
[0447] Optionally, in some embodiments, the time-frequency resources of different signals may or may not overlap in the frequency domain. For example, the first signal and the second signal may be mapped to the same frequency resource. Alternatively, the first signal and the second signal may be mapped to different frequency resources. Alternatively, the first signal and the third signal may be mapped to the same frequency resource. Alternatively, the first signal and the third signal may be mapped to different frequency resources. Alternatively, the second signal and the third signal may be mapped to the same frequency resource. Alternatively, the second signal and the third signal may be mapped to different frequency resources.
[0448] Optionally, in some embodiments, the time-frequency resources configured by the network device may be used for the terminal to communicate with one first device, a group of first devices, or multiple first devices, wherein the group of first devices may include at least one first device.
[0449] Optionally, in some embodiments, after the network device configures the time-frequency resources for at least one of the first signal, the second signal, the third signal, and the fourth signal, the configured time-frequency resources need to be activated before they can be used. In some embodiments, after the network device configures the time-frequency resources for at least one of the first signal, the second signal, the third signal, and the fourth signal, the time-frequency resources configured by the network device may be activated simultaneously by default. Alternatively, in other embodiments, after the network device is configured with time-frequency resources for at least one of the first signal, the second signal, the third signal, and the fourth signal, the network device may also send a first signaling and / or a second signaling, wherein the first signaling may be used to activate the time-frequency resources of the first signal configured by the network device when there is no need to schedule the communication transmission of the first device, so that the terminal sends the first signal based on the time-frequency resources of the first signal, thereby charging the first device; the second signaling may be used to activate the time-frequency resources of at least one of the second signal, the third signal, and the fourth signal configured by the network device when it is necessary to schedule the communication transmission of the first device, so that the second signal, the third signal, and the fourth signal can be transmitted between the terminal and the first device based on the time-frequency resources of the second signal, the third signal, and the fourth signal.
[0450] Optionally, in some embodiments, when the time-frequency resources configured by the network device are used for communication between the terminal and a first device or a group of first device groups, the above-mentioned first signaling and / or second signaling may be used to activate the time-frequency resources configured to the first device or the first device group by indicating the device identification (Identity, ID) of the first device or the group ID of the first device group.
[0451] Optionally, in some embodiments, the first signaling and / or the second signaling may be downlink control information (DCI).
[0452] Optionally, in some embodiments, the time-frequency resources of the first signal corresponding to different types of first devices are the same or different, the time-frequency resources of the second signal corresponding to different types of first devices are the same or different, the time-frequency resources of the third signal corresponding to different types of first devices are the same or different, and the time-frequency resources of the fourth signal corresponding to different types of first devices are the same or different. Optionally, the different types of first devices may include, for example: A-IoT device A, A-IoT device B, and A-IoT device C.
[0453] For example, in some embodiments, the time-frequency resources of the first signals corresponding to A-IoT device A, A-IoT device B, and A-IoT device C may be the same or different.
[0454] For example, in some embodiments, the time-frequency resources of the third signal corresponding to A-IoT device A, A-IoT device B, and A-IoT device C may be the same, or the time-frequency resources of the third signal corresponding to A-IoT device A, A-IoT device B, and A-IoT device C may be different. Specifically, since different types of A-IoT devices have different receiving sensitivities, the time-frequency resources of the third signal corresponding to A-IoT device A, A-IoT device B, and A-IoT device C should be different to ensure that the time-frequency resources of the third signal corresponding to A-IoT device A can meet the receiving sensitivity of A-IoT device A, the time-frequency resources of the third signal corresponding to A-IoT device B meet the receiving sensitivity of A-IoT device B, and the time-frequency resources of the third signal corresponding to A-IoT device C meet the receiving sensitivity of A-IoT device C; or, the time-frequency resources of the third signal corresponding to A-IoT device A and A-IoT device B may be the same, while the time-frequency resources of the third signal corresponding to A-IoT device C are different from the time-frequency resources of the third signal corresponding to A-IoT device A and A-IoT device B.
[0455] For example, in some embodiments, the time-frequency resources of the second signal corresponding to A-IoT device A and A-IoT device B are the same, and the time-frequency resources of the fourth signal corresponding to A-IoT device A and A-IoT device B are the same; or, the time-frequency resources of the second signal corresponding to A-IoT device A and A-IoT device B are different, and the time-frequency resources of the fourth signal corresponding to A-IoT device A and A-IoT device B are different; wherein, since the activation power of A-IoT device A and A-IoT device B is different, and the supported transmission power is also different, A-IoT device A and A-IoT device B should be made to The time-frequency resources of the second signal corresponding to A-IoT device A should be different to ensure that the time-frequency resources of the second signal corresponding to A-IoT device A can meet the activation power of A-IoT device A, and the time-frequency resources of the second signal corresponding to A-IoT device B can meet the activation power of A-IoT device B; and the time-frequency resources of the fourth signal corresponding to A-IoT device A and A-IoT device B should be different to ensure that the time-frequency resources of the fourth signal corresponding to A-IoT device A can meet the transmission power of A-IoT device A, and the time-frequency resources of the fourth signal corresponding to A-IoT device B can meet the transmission power of A-IoT device B.
[0456] For example, in some embodiments, the time-frequency resources of the fourth signal corresponding to the A-IoT device C may be different from the time-frequency resources of the fourth signals corresponding to the A-IoT device A and the A-IoT device B.
[0457] Step 2102: The terminal and / or the first device determines the time-frequency resources of at least one of the first signal, the second signal, the third signal, and the fourth signal, and the time-frequency resources of different signals do not overlap in the time domain.
[0458] Optionally, the terminal and / or the first device can determine the time-frequency resources of at least one of the first signal, the second signal, the third signal, and the fourth signal based on the configuration of the network device, or can determine the time-frequency resources of at least one of the first signal, the second signal, the third signal, and the fourth signal based on protocol predefinition.
[0459] Optionally, for a detailed introduction to the first signal, the second signal, the third signal, the fourth signal and the corresponding time-frequency resources, reference may be made to the above step descriptions.
[0460] Optionally, in some embodiments, after receiving the time-frequency resources of at least one of the first signal, the second signal, the third signal, and the fourth signal configured by the network device, the terminal and / or the first device may directly activate the time-frequency resources configured by the network device;
[0461] Optionally, in some other embodiments, the terminal and / or the first device may further receive first signaling sent by the network device, where the first signaling is used to activate time-frequency resources of the first signal configured by the network device when there is no need to schedule communication transmission of the first device;
[0462] Optionally, in some further embodiments, the terminal and / or the first device may also receive a second signaling sent by the network device, where the second signaling is used to activate the time-frequency resources of at least one of the second signal, the third signal, and the fourth signal configured by the network device when it is necessary to schedule the communication transmission of the first device.
[0463] For detailed description of the first signaling and the second signaling, please refer to the above embodiment description.
[0464] It should be noted that, in some embodiments, for the first device, part or all of the time-frequency resources of the first signal, the time-frequency resources of the second signal, the time-frequency resources of the third signal, and the time-frequency resources of the fourth signal may be transparent; that is, for the first device, it does not determine the time-frequency resources of the first signal, the time-frequency resources of the second signal, the time-frequency resources of the third signal, and the time-frequency resources of the fourth signal, and does not know on which time-frequency resources the first signal, the second signal, the third signal, and the fourth signal are specifically transmitted. At this time, the first device only passively receives (for example, blindly detects) the first signal, the second signal, and the third signal, and, because it does not know the time-frequency resources of the fourth signal, it cannot actively transmit the fourth signal. It can only send the fourth signal by backscattering the second signal after receiving the second signal. When the first device sends the fourth signal by backscattering the second signal, since it has received the second signal, the first device can directly backscatter the fourth signal based on the second signal. For a detailed introduction to backscattering, please refer to the above content.
[0465] Step 2103: The terminal and the first device communicate based on the time-frequency resources configured by the network device.
[0466] Optionally, the terminal can send a first signal to the first device based on the time-frequency resources of the first signal, send a second signal to the first device based on the time-frequency resources of the second signal, send a third signal to the first device based on the time-frequency resources of the third signal, and receive a fourth signal sent by the first device based on the time-frequency resources of the fourth signal.
[0467] Optionally, the first device can receive the first signal based on the time-frequency resources of the first signal, receive the second signal based on the time-frequency resources of the second signal, receive the third signal based on the time-frequency resources of the third signal, and send the fourth signal based on the time-frequency resources of the fourth signal.
[0468] 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.
[0469] In the above embodiment, the terminal determines the time-frequency resources of at least one of the first signal, the second signal, the third signal, and the fourth signal, wherein the first signal, the second signal, the third signal, and the fourth signal are signals required for communication between the terminal and the first device, and the terminal determines the time-frequency resources of at least one of the first signal, the second signal, the third signal, and the fourth signal, so that it can subsequently send at least one of the first signal, the second signal, and the third signal to the first device based on the determined time-frequency resources, and / or receive the fourth signal sent by the first device, thereby achieving successful communication between the terminal and the first device and ensuring efficient data transmission between the terminal and the first device.
[0470] The resource determination 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+step 2102 may be implemented as an independent embodiment, but the present invention is not limited thereto.
[0471] 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.

[0483] Optionally, when the first time-frequency resource is a time-frequency resource shared by at least two of the first signal, the second signal, and the third signal. If the terminal also supports receiving a fourth signal, then when the terminal sends the second signal on the first time-frequency resource, it also detects the fourth signal on the first time-frequency resource. At this time, the terminal is in full-duplex working mode; if the terminal does not support receiving the fourth signal, at this time, the fourth signal is received by another terminal, and the other terminal is a device that supports receiving the fourth signal. The other terminal is used to detect the fourth signal on the first time-frequency resource.

[0488] 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.
[0489] FIG2C is an interactive diagram of a resource determination method according to an embodiment of the present disclosure. As shown in FIG2C , the embodiment of the present disclosure relates to a resource determination method for a communication system 100, the method comprising:
[0490] Step 2301: The network device configures time-frequency resources for at least one of the first signal, the second signal, the third signal, and the fourth signal, wherein at least two of the time-frequency resources of the first signal, the time-frequency resources of the second signal, the time-frequency resources of the third signal, and the time-frequency resources of the fourth signal meet the first condition.
[0491] Optionally, the first condition may include at least one of the following:
[0492] At least two of the time-frequency resources of the first signal, the time-frequency resources of the second signal, the time-frequency resources of the third signal, and the time-frequency resources of the fourth signal overlap in the time domain;
[0493] The time difference between at least one of the time-frequency resources of the first signal, the time-frequency resources of the second signal, and the time-frequency resources of the third signal and the time-frequency resources of the fourth signal is less than the first time; the first time is: the conversion time required between the first transmission and the second transmission; the first transmission is: the transmission from the terminal to the first device; the second transmission is: the terminal receives the transmission from the first device.
[0494] Optionally, when at least two time-frequency resources meet the first condition, it indicates that there is currently a transmission conflict.
[0495] Step 2302: The terminal and / or the first device determines the time-frequency resources of at least one of the first signal, the second signal, the third signal, and the fourth signal, wherein at least two of the time-frequency resources of the first signal, the time-frequency resources of the second signal, the time-frequency resources of the third signal, and the time-frequency resources of the fourth signal meet the first condition.
[0496] For a detailed description of steps 2301 - 2302 , please refer to the above embodiment description.
[0497] Step 2303: The terminal communicates with the first device based on the time-frequency resources configured by the network device.
[0498] In some embodiments, when the terminal supports sending different signals, the method in which the terminal communicates with the first device based on the time-frequency resources configured by the network device may also be different.
[0499] Optionally, when the terminal supports sending the first signal and the second signal, and the time-frequency resources of the first signal and the time-frequency resources of the second signal meet the first condition, the terminal sends the second signal at the overlapping time of the time-frequency resources of the first signal and the time-frequency resources of the second signal, or the terminal determines that an error occurs in resource allocation. Optionally, if the terminal supports receiving the fourth signal, the terminal can detect the fourth signal while sending the second signal. Optionally, the above-mentioned "the terminal supports sending the first signal and the second signal" can be understood as: the terminal has the ability to send the first signal and the second signal, and the network device configures the terminal to send the first signal and the second signal. The concept of "the terminal supports sending a certain signal" in the subsequent content is similar to this and will not be repeated hereafter. Optionally, in some embodiments, since the second signal can not only stimulate the first device to perform backscatter communication, but also be used to charge the first device, the second signal can also be used as the first signal. Therefore, when the terminal supports sending the first signal and the second signal, the terminal can choose to send the second signal, so as to achieve the effects of charging and stimulating the first device at the same time.
[0500] Optionally, when a terminal supports sending the first signal but does not support sending the second signal, and the terminal can obtain time-frequency resources for the second signal, and the time-frequency resources of the first signal and the second signal meet a first condition, the terminal may transmit the second signal during the overlapping time of the time-frequency resources of the first signal and the second signal. Alternatively, the terminal may not transmit the first signal during the overlapping time of the time-frequency resources of the first signal and the second signal, or the terminal may determine that a resource allocation error has occurred. Optionally, the term "available" in the aforementioned "the terminal can obtain the time-frequency resources for the second signal" can be understood to mean that the terminal can obtain the time-frequency resources for the second signal through at least one of network device configuration, protocol pre-definition, or transmission by another terminal, where the other terminal may be, for example, a terminal that supports sending the second signal. Optionally, the term "the terminal does not support sending the second signal" can be understood to mean that the terminal has the capability to send the second signal, but the network device has not configured the terminal to do so. The concept of "the terminal does not support sending a certain signal" in the subsequent content is similar and will not be further described. Furthermore, in some embodiments, when the terminal supports sending a first signal but does not support sending a second signal, if the terminal chooses to send the second signal at the overlapping time of the time-frequency resources of the first signal and the time-frequency resources of the second signal, the terminal can send the second signal based on the time-frequency resources of the second signal that it can obtain.
[0501] Optionally, when the terminal does not support sending the first signal but supports sending the second signal, and the terminal can obtain the time-frequency resources of the first signal, and the time-frequency resources of the first signal and the time-frequency resources of the second signal meet the first condition, the terminal may send the second signal on the time-frequency resources of the second signal, or the terminal determines that a resource allocation error occurred.

[0710] The following is an exemplary introduction to the above method.
[0711] To further conserve power and reduce device complexity, a notable feature of new IoT devices is that they harvest energy from the environment and use it for communication. This new device is referred to as an A-IoT device (i.e., the first device in the aforementioned embodiment). A-IoT devices have broad application prospects, including equipment identification and sensors for warehousing, eliminating the cost of configuring and replacing batteries.
[0712] A-IoT devices can be divided into three categories. Type A devices (i.e., A-IoT device A in the aforementioned embodiment) 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. In fact, type A devices need to receive wireless signals to obtain energy to activate the internal receiving and processing module. Type B devices (i.e., A-IoT device B in the aforementioned embodiment) 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 (i.e., A-IoT device C in the aforementioned embodiment) 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.
[0713] To support energy storage and backscatter transmission of A-IoT devices, energy-related functions in the network can be divided into two types, namely:
[0714] As an excitation (Continuous Wave, CW) (the second signal mentioned above), it is only used for Devices A and B. CW is actually also an ES. A-IoT devices can receive CW and store energy.
[0715] The Energy Source (ES) function (i.e., the aforementioned first signal) can be used for device types B and C. For device type A, because its supported energy storage capacity is very limited, ES signals other than CW can be undefined. Alternatively, ES signals can also be used for device type A.
[0716] Furthermore, in order to support data transmission of A-IoT devices, the network also needs to support the following functions.
[0717] The downlink transmission (DT) (i.e., the third signal mentioned above) function sends indication information to the A-IoT device, thereby triggering the uplink transmission of the A-IoT device.
[0718] The uplink reception (UR) (i.e., the aforementioned fourth signal) function receives the uplink information backscattered by the A-IoT device, or receives the uplink information actively transmitted by the A-IoT device.
[0719] A device may support only one of the above functions. Alternatively, a device may support multiple functions at the same time. Alternatively, a device may support all of the above functions at the same time. For example, a device may support only one type of energy function, or a device may support both types of energy functions at the same time. The device may also perform uplink and downlink transmission of the cellular network. In particular, a channel or signal may support both ES and CW functions at the same time, so that only resource configuration needs to be performed on the channel or signal.
[0720] The various functions described above have different purposes and may employ different multiplexing methods with the cellular network's uplink and downlink transmissions. Accordingly, the network can coordinate configuration or dynamically instruct one or more devices to allocate resources for these functions. The configuration of the ES, CW, DT, and UR functions described above can be partially or entirely transparent to the A-IoT device.
[0721] Example 1
[0722] The resources of one or more devices for the above-mentioned functions DT, CW, UR and ES may be configured separately.
[0723] To support communication for one, a group of, or all A-IoT devices, the configuration of the DT function may include the following parameters:
[0724] Time resources. The configuration parameters may include at least part of the following parameters:
[0725] a) Cycle, offset, and duration of the time period for allocating DT resources within each cycle. In particular, the duration can be equal to the cycle.
[0726] b) Continuous DT resources may be configured within the duration, or the DT resources configured within the duration may be indicated by a bitmap. Each bit of the bitmap corresponds to one or more consecutive OFDM symbols, one or more consecutive time slots, one or more consecutive subframes, one or more consecutive radio frames, etc.
[0727] Frequency resources. The frequency resources occupied by DT resources can be:
[0728] a) One subcarrier
[0729] b) A group of consecutive subcarriers
[0730] c) A group of equally spaced subcarriers, i.e., a comb-shaped CW subcarrier is mapped to a relatively wide frequency band, which can combat frequency selective fading.
[0731] d) One PRB.
[0732] e) A PRB set. In particular, DT resources can be transmitted over the entire bandwidth allocated for A-IoT transmission.
[0733] Frequency hopping related parameters
[0734] Beam configuration can be handled by one of the following methods:
[0735] a) DT resource omnidirectional transmission
[0736] b) Configure the beam information of DT resources
[0737] To support communication with one, a group of, or all A-IoT devices, the CW function configuration may include the following parameters:
[0738] Time resources. The configuration parameters may include at least part of the following parameters:
[0739] a) Cycle, offset, and duration of the time period allocated to the CW within each cycle. In particular, the duration can be equal to the cycle.
[0740] b) Continuous CWs may be configured within the duration, or the CWs configured within the duration may be indicated by a bitmap. Each bit of the bitmap corresponds to one or more consecutive OFDM symbols, one or more consecutive time slots, one or more consecutive subframes, one or more consecutive radio frames, etc.
[0741] c) Timing advance Te: That is, the energy node can start sending CWs Te ahead of the configured start time. The CWs in the Te time period can be used to charge and activate Device A. For Device B, Te can be equal to 0.
[0742] Frequency resources. The frequency resources occupied by CW can be:
[0743] a) One subcarrier
[0744] b) A group of consecutive subcarriers, such as a PRB
[0745] c) A group of equally spaced subcarriers, i.e., a comb. The comb-shaped CW subcarriers are mapped to a relatively wide frequency band. Accordingly, the A-IoT device also backscatters all CW subcarriers, thereby combating frequency selective fading.
[0746] For example, as shown in Figure 2A2 above, the transmitter can transmit two widely spaced single-frequency CW signals. Three A-IoT devices then backscatter and modulate the signals on each of these two CWs. For each A-IoT device, the backscattered signal is located near the two CWs, and each CW includes two sidebands. Because the two CWs can be spaced relatively far apart, significant frequency diversity gain is achieved.
[0747] Frequency hopping related parameters
[0748] Sequence resources. A CW can be a continuous constant-amplitude wave, for example, a constant-amplitude sine wave mapped to a subcarrier for transmission. When a CW is mapped to multiple subcarriers, the CW symbol sequence on each subcarrier can be processed using one of the following methods to achieve interference averaging.
[0749] a) Predefine or configure CW sequence
[0750] b) The CW sequence can be randomly generated, and the specific form of the CW depends on the implementation of the energy node.
[0751] Beam configuration can be handled by one of the following methods:
[0752] a) CW omnidirectional transmission
[0753] b) Configure CW beam information
[0754] To support communication for one, a group, or all A-IoT devices, the UR function can be configured using the same methods as the CW function. An additional parameter is the frequency location of the uplink signal that the A-IoT device backscatters from the CW. For example, as shown in Figure 2A2, the backscattered uplink signal can be configured to occupy different channels on either side of the CW.
[0755] To support communication with one, a group of, or all A-IoT devices, the ES function configuration may include the following parameters:
[0756] Time resources. The configuration parameters may include at least part of the following parameters:
[0757] a) Period, offset, and duration of the time period allocated to the ES signal within each period. In particular, the duration can be equal to the period.
[0758] b) Continuous ES signals may be configured within the duration, or the ES signals configured within the duration may be indicated by a bitmap. Each bit of the bitmap corresponds to one or more consecutive OFDM symbols, one or more consecutive time slots, one or more consecutive subframes, one or more consecutive radio frames, etc.
[0759] Frequency resources. The frequency resources occupied by ES signals can be:
[0760] a) One subcarrier.
[0761] b) A group of consecutive subcarriers
[0762] c) A group of equally spaced subcarriers, i.e., a comb-shaped CW subcarrier is mapped to a relatively wide frequency band, which can combat frequency selective fading.
[0763] d) One PRB.
[0764] e) A PRB set. In particular, ES signals can be transmitted over the entire bandwidth allocated for A-IoT transmission.
[0765] Frequency hopping related parameters
[0766] Sequence or information carried. The ES signal can be a continuous constant amplitude wave, for example, the ES signal is a constant amplitude sine wave mapped to a subcarrier for transmission. When the ES signal is mapped to multiple subcarriers, the ES signal symbol sequence on each subcarrier can be processed by one of the following methods
[0767] a) Predefine or configure the sequence of ES signals
[0768] b) Information carried by predefined or configured ES signals. Note: This information is only used to generate ES signals and is transparent to A-IoT devices.
[0769] c) ES signals can be randomly generated, and the specific form of ES signals depends on the implementation of energy nodes.
[0770] d) ES signals can also reuse cellular communication uplink and downlink channels or signals, such as PUSCH or SRS. These uplink and downlink channels or signals can be used to power A-IoT devices in addition to their cellular communication functions. Alternatively, these uplink and downlink channels or signals can be additionally configured or scheduled for powering A-IoT devices.
[0771] Beam configuration can be handled by one of the following methods:
[0772] a) ES signal omnidirectional transmission
[0773] b) Configure the beam information of the ES signal
[0774] The network can use RRC signaling to configure a device's resources for transmitting ES signals. The above-mentioned ES signal can be directly activated after configuration, that is, a device transmits the ES signal according to the configuration of the ES signal. Alternatively, after configuring the above-mentioned ES signal, the network can further transmit downlink control information (DCI) to send information indicating activation or deactivation of the ES signal. The above-mentioned DCI can also adjust the allocated resources of the ES signal. For example, for the ES signal configured for a group of A-IoT devices, the network can activate the ES signal for this group of A-IoT devices by indicating the group ID of the group of A-IoT devices when there is no need to schedule uplink and downlink data transmission of the group of A-IoT devices.
[0775] The network can use RRC signaling to configure a device's resources for transmitting CW. The above-mentioned CW can be directly activated after configuration, that is, a device transmits CW according to the configuration of CW. Alternatively, after configuring the above-mentioned CW, the network may further transmit downlink control information (DCI) to send information indicating activation or deactivation of the above-mentioned CW. The above-mentioned DCI can also adjust the allocated resources of CW. For example, for the CW configured for a group of A-IoT devices, the network may activate the CW for this group of A-IoT devices by indicating the group ID of the group of A-IoT devices when it needs to schedule data transmission of the group of A-IoT devices.
[0776] The network can use RRC signaling to configure a device's UR resources for receiving uplink transmissions from A-IoT devices. The above-mentioned UR resources can be directly activated after configuration, that is, a device receives uplink transmissions from A-IoT devices according to the UR configuration. Alternatively, after configuring the above-mentioned UR resources, the network may further transmit downlink control information (DCI) to send information indicating activation or deactivation of the above-mentioned UR resources. The above-mentioned DCI can also adjust the allocated UR resources. For example, for UR resources configured for a group of A-IoT devices, the network may activate the UR resources for this group of A-IoT devices by indicating the group ID of the group of A-IoT devices when it needs to schedule data transmission of the group of A-IoT devices.
[0777] The network can use RRC signaling to configure a device's resources for transmitting DT. The above-mentioned DT resources can be directly activated after configuration, that is, a device transmits downlink information according to the configuration of DT. Alternatively, after configuring the above-mentioned DT resources, the network can further transmit downlink control information (DCI) to send information indicating activation or deactivation of the above-mentioned DT resources. The above-mentioned DCI can also adjust the allocated DT resources. For example, for the DT resources configured for a group of A-IoT devices, the network can activate the DT resources for this group of A-IoT devices by indicating the group ID of the group of A-IoT devices when it needs to schedule data transmission of the group of A-IoT devices.
[0778] For ES signals, the ES signals configured or dynamically indicated by the base station may be transparent to the UE transmitting the ES signal. That is, the UE transmits the uplink channel / signal according to the resource allocation of the base station, and the UE may not be aware that the uplink channel / signal it transmits is also used as an ES signal.
[0779] Using the above method, the ES signal and CW can be mapped to the same frequency resource. Alternatively, the ES signal and CW can be mapped to different frequency resources. Using the above method, the ES signal and DT resource can be mapped to the same frequency resource. Alternatively, the ES signal and DT resource can be mapped to different frequency resources. Using the above method, the CW and DT resource can be mapped to the same frequency resource. Alternatively, the CW and DT resource can be mapped to different frequency resources.
[0780] The network can configure or dynamically indicate the same ES resources for A-IoT device types B and C. Alternatively, the network can configure or dynamically indicate ES resources for A-IoT device types B and C separately. The method can also be applied to device type A.
[0781] The network can configure or dynamically indicate the same DT resources for multiple A-IoT device types. Alternatively, the network can configure or dynamically indicate DT resources separately for different A-IoT device types. Different A-IoT device types have different reception sensitivities, and therefore require different downlink DT transmission parameters. Alternatively, the network can configure or dynamically indicate DT resources for A-IoT device types A and B, and configure or dynamically indicate DT resources separately for A-IoT device type C.
[0782] The network can configure or dynamically indicate the same CW and UR resources for A-IoT device types A and B. Alternatively, the network can configure or dynamically indicate CW and UR resources separately for A-IoT device types A and B. Here, A-IoT device types A and B have different activation powers and support different uplink transmission powers, resulting in correspondingly different requirements for CW transmission parameters and uplink reception UR. The network independently configures or dynamically indicates UR resources for A-IoT device type C.
[0783] Example 2
[0784] Part or all of the above functions DT, CW, UR and ES of one or more devices may be configured as shared resources.
[0785] The network can configure a shared time-frequency resource for CW and UR. For example, CW and UR can be configured with the same time resource. The frequency resource of CW and UR can be the same subcarrier, a group of the same subcarriers, or the same PRB. Alternatively, the frequency resource of UR can be the frequency resource of CW superimposed with a frequency offset. For example, as shown in Figure 1, the frequency resource of UR can be the channels located on both sides of CW. Assuming that the CW function and the UR function are located in the same device X, within this resource, the device X can receive the uplink transmission UR backscattered by the A-IoT device while sending CW, that is, the device X is in full-duplex working mode. Alternatively, assuming that the UR function is located in another device Y, and device Y is able to obtain the shared time-frequency resource allocation of the CW and UR, device Y can detect the A-IoT backscattered signal on the shared time-frequency resource.
[0786] The network can use RRC signaling to configure a device's shared resources for CW and UR. The above-mentioned shared resources can be directly activated after configuration, that is, a device transmits CW and / or receives backscattered uplink transmission UR according to the configuration of the shared resources. Alternatively, after configuring the above-mentioned shared resources, the network may further transmit downlink control information (DCI) to send information indicating activation or deactivation of the shared resources. The above-mentioned DCI can also adjust the allocated shared resources. For example, for the shared resources configured for a group of A-IoT devices, the network may activate the shared resources for this group of A-IoT devices by indicating the group ID of the group of A-IoT devices when it needs to schedule uplink and downlink data transmission of the group of A-IoT devices.
[0787] The network can configure a shared time-frequency resource for DT and CW, and independently configure the time-frequency resources for ES. For example, DT and CW can occupy the same subcarrier, the same group of subcarriers, or the same PRB. Assuming that the DT function and the CW function are located in the same device X, within this resource, the device X can independently decide to execute the uplink transmission of the A-IoT device supporting the sending of downlink information to A-IoT (i.e., DT) or the sending of the excitation signal CW. Using this method, assuming that the UR function is also located in device X, device X can detect the A-IoT backscattered signal on the resource while transmitting CW. Alternatively, assuming that the UR function is located in another device Y, and device Y cannot obtain the resource allocation of DT and CW of device X in a timely manner, device Y can detect the A-IoT backscattered signal on all resources of the shared time-frequency resource.
[0788] The network can use RRC signaling to configure a device's shared resources for DT and CW. The above-mentioned shared resources can be directly activated after configuration, that is, a device performs downlink transmission of DT or transmission of CW according to the configuration of the shared resources. Alternatively, after configuring the above-mentioned shared resources, the network may further transmit downlink control information (DCI) to send information indicating activation or deactivation of the shared resources. The above-mentioned DCI can also adjust the allocated shared resources. For example, for the shared resources configured for a group of A-IoT devices, the network may activate the shared resources for this group of A-IoT devices by indicating the group ID of the group of A-IoT devices when it needs to schedule uplink and downlink data transmission of the group of A-IoT devices.
[0789] Assume that the network can configure a shared time-frequency resource for DT, CW, and ES. For example, DT, CW, and ES can occupy the same subcarrier, the same group of subcarriers, or the same PRB. Assume that the DT function, CW function, and ES function are located in the same device X. Within this resource, the device X can independently decide to send downlink information to A-IoT (i.e., DT), send an excitation signal CW to support uplink transmission of A-IoT devices, or only send ES signals for A-IoT device energy storage. Using this method, assuming that the UR function is also located in device X, device X can detect the A-IoT backscattered signal on the resource while transmitting CW. Alternatively, assuming that the UR function is located in another device Y, and device Y cannot obtain the resources used by device X for CW in a timely manner, device Y can detect the A-IoT backscattered signal on all resources of the shared time-frequency resource.
[0790] The network can use RRC signaling to configure a device's shared resources for DT, CW, and ES. The above-mentioned shared resources can be directly activated after configuration, that is, a device performs downlink transmission of DT, CW, or ES signals according to the configuration of the shared resources. Alternatively, after configuring the above-mentioned shared resources, the network may further transmit downlink control information (DCI) to send information indicating activation or deactivation of the shared resources. The above-mentioned DCI can also adjust the allocated shared resources. For example, for the shared resources configured for a group of A-IoT devices, the network may activate the shared resources for this group of A-IoT devices by indicating the group ID of the group of A-IoT devices when it needs to schedule uplink and downlink data transmission of the group of A-IoT devices.

[0792] The network-configured or dynamically scheduled DT, CW, UR, and ES resources may overlap in time, or there may not be sufficient uplink / downlink transition time between resources. Accordingly, the device behavior needs to be defined.
[0793] In some embodiments, if the ES and CW functions reside on the same device X, and the configured ES and CW resources overlap in time, device X transmits CW during the overlapping time. CW is also an ES signal, enabling energy nodes to transmit both ES and CW simultaneously. If device X also includes UR functionality, device X can simultaneously detect A-IoT backscattered signals while transmitting CW. Alternatively, the above situation constitutes an error configuration.
[0794] In some embodiments, if the ES functionality resides on device X and the CW functionality resides on device Y, and the configured ES and CW resources overlap in time, and device X is able to obtain the CW resources allocated to device Y, device X can transmit CWs during the overlapping time, while device Y continues to transmit CWs as configured. Alternatively, device X may not transmit ES during the overlapping time, while device Y continues to transmit CWs as configured. If device Y also includes UR functionality, device Y can detect A-IoT backscattered signals while transmitting CWs. Alternatively, the above situation is a misconfiguration.
[0795] In some embodiments, if the ES and UR functions are located on the same device X, and device X does not include a CW function, and the configured ES and UR resources overlap in time, or there is insufficient uplink / downlink transition time between the resources, device X performs uplink UR reception during the overlapping time, but does not transmit the ES. Alternatively, the above situation is a misconfiguration.
[0796] In some embodiments, if the ES function is located on device X and the UR function is located on device Y, and the configured ES and UR resources overlap in time, or there is insufficient uplink and downlink transition time between the resources, and device X is able to obtain the UR resources configured for device Y, then device X may not transmit the ES during the overlapping time. Alternatively, the above situation is a misconfiguration.
[0797] In some embodiments, if the ES and DT functions reside on the same device X, and the configured ES and DT resources overlap in time, device X will downlink the DT during the overlapping time. The DT can also function as an ES signal, enabling the energy node to simultaneously transmit both the ES signal and the DT. Alternatively, the above situation represents an incorrect configuration.
[0798] In some embodiments, if the ES function is located on device X and the DT function is located on device Y, and the configured ES and DT resources overlap in time, and device X is able to obtain the DT resources configured for device Y, then device X will not transmit ES signals during the overlapping time, and device Y will still perform downlink DT transmissions as configured. Alternatively, assuming that device X is aware of the downlink information and other transmission parameters to be sent by device Y, device X can transmit the same downlink signal as device Y during the overlapping time. Alternatively, the above situation is a misconfiguration.
[0799] In some embodiments, if the CW function and the UR function are located on the same device X, and the configured CW resources and UR resources do not completely overlap in time, device X may transmit CWs on the intersection of the CW and UR resources and receive uplink transmissions backscattered by the A-IoT device. Alternatively, device X may transmit CWs on the union of the CW and UR resources and receive uplink transmissions backscattered by the A-IoT device. Alternatively, device X may transmit CWs on CW resources and receive uplink transmissions backscattered by the A-IoT device on UR resources. Alternatively, the above situations are misconfigured.
[0800] In some embodiments, if the CW function is located on device X and the UR function is located on device Y, the configured CW resources and UR resources do not completely overlap in time, and devices X and Y are able to obtain the configured UR and CW resources, then the CW may be transmitted on the intersection of the CW resources and the UR resources, and device Y may receive the uplink transmission backscattered by the A-IoT device on the intersection. Alternatively, device X may transmit the CW on the union of the CW resources and the UR resources, and device Y may receive the uplink transmission backscattered by the A-IoT device on the union. Alternatively, device X may transmit the CW on the CW resources, and device Y may receive the uplink transmission backscattered by the A-IoT device on the UR resources. Alternatively, the above situation is an incorrect configuration.
[0801] In some embodiments, if the CW and DT functions reside on the same device X, and the configured CW and DT resources overlap in time, device X transmits CW at the overlapping time. Using this approach, if the UR function resides on another device Y, device Y can still receive uplink transmissions from the A-IoT device according to the CW or UR configuration. Alternatively, device X can perform downlink DT transmissions at the overlapping time. Alternatively, the decision to perform downlink DT transmissions or CW transmissions at the overlapping time depends on the implementation of device X. Alternatively, the above situations are misconfigured.
[0802] In some embodiments, if the CW function is located on device X and the DT function is located on device Y, the configured CW and DT resources overlap in time, and both devices X and Y have access to the configured DT and CW resources, then device X transmits CWs during the overlapping time, while device Y does not perform downlink DT transmissions during the overlapping time. Alternatively, device X does not transmit CWs during the overlapping time, while device Y performs downlink DT transmissions during the overlapping time. Alternatively, the above situations constitute misconfiguration.
[0803] In some embodiments, if the UR and DT functions reside on the same device X, and the configured UR and DT resources overlap in time, or if there's insufficient uplink / downlink transition time between the resources, device X performs uplink transmissions (UR) during the overlapping time. Using this approach, if the CW function resides on another device Y, device Y can still transmit CWs according to the CW configuration. Alternatively, device X performs downlink transmissions (DTs) during the overlapping time. Alternatively, the decision to perform downlink transmissions (DTs) or uplink receptions (URs) during the overlapping time depends on the implementation of device X. Alternatively, the above situations represent misconfigurations.
[0804] In some embodiments, if the UR function is located on device X and the DT function is located on device Y, the configured UR and DT resources overlap in time, or there is insufficient uplink to downlink transition time between the resources, and devices X and Y are able to obtain the configured DT and CW resources, then device X performs uplink UR reception during the overlapping time, while device Y does not perform downlink DT transmission during the overlapping time. Alternatively, device X does not perform uplink UR reception during the overlapping time, while device Y performs downlink DT transmission during the overlapping time. Alternatively, the above situations constitute misconfiguration.
[0805] In some embodiments, if any one of the CW, UR, and DT functions and the ES function are located in the same device X, the configured ES resources and the resources of any one of the functions overlap in time, or there is insufficient uplink and downlink switching time between the resources, then the device X executes any one of the functions at the overlapping time.
[0806] In some embodiments, if the ES function is located in device X, and any one of the CW, UR, and DT functions is located in device Y, the configured ES resources and the resources of the any one function overlap in time, or there is insufficient uplink and downlink switching time between the resources, and device X can obtain the resources configured for the any one function of device Y, then device X does not transmit the ES at the overlapping time, and device Y performs the any one function at the overlapping time.
