The CU-DU structure can separate the protocol layer of the access network device. Some of the protocol layer functions are centrally controlled by the CU, while the remaining part or all of the protocol layer functions are distributed in the DU and centrally controlled by the CU. However, this is not the only possibility.

[0155] In some embodiments, A-IoT devices can be applied to scenarios involving large-scale inventory management of items. Specifically, the A-IoT device reports its EPC (Electronic Product Code) to the network / intermediate node X / UE, and inventory is performed based on this EPC. A-IoT devices can also be applied to sensing scenarios such as smart homes and environmental monitoring, reporting relevant data when certain trigger conditions are met. For example, A-IoT devices can also be used in location scenarios to find items or locate A-IoT devices within a shopping mall. They can also be used in command scenarios to respond to commands sent by network devices.

[0156] In some embodiments, A-IoT devices may include multiple types, (1) the peak power consumption of the A-IoT device is 1μW, the device has energy storage function, and the device's SFO (Sampling Frequency Offset) is 10. X ppm, the internal device in the device configuration has neither DL (Down Link) signal amplification function nor UL (Up Link) signal amplification function. The UL transmission of the device is backscattered through an externally provided carrier. (2) The peak power consumption of the A-IoT device is less than 100μW. The device has energy storage function and the SFO of the device can reach 10 X ppm, in this A-IoT device, can amplify DL and / or UL signals. The device's UL transmission can be generated internally or through backscattering of an externally provided carrier.

[0157] In some embodiments, A-IoT devices may include multiple types: (1) The peak power consumption of the A-IoT device is 1 μW. The device has energy storage capabilities but cannot independently generate or amplify UL and / or DL ​​signals. It transmits signals through a backscattering operation. The device does not have the capability to amplify DL and / or UL signals. (2a) The peak power consumption of the A-IoT device is greater than 200 μW. The device has energy storage capabilities but cannot independently generate communication signals. It can transmit signals using a backscattering operation. The A-IoT device can use the stored energy to amplify DL and / or UL signals. (2b) The peak power consumption of the A-IoT device is greater than 200 μW. The device has energy storage capabilities and can independently generate signals. For example, the A-IoT device has an RF (Radio Frequency) module for actively transmitting signals. (2c) The A-IoT device has both the capability to actively transmit communication information and the capability to backscatter.

[0158] In some embodiments, A-IoT devices may include multiple types, such as: (1) Device-A: Cannot perform independent signal generation / amplification, for example, using a backscattering working mode, and does not have the ability to amplify DL and / or UL signals. (2) Device-B: Has energy storage capability, cannot perform independent signal generation, for example, using a backscattering working mode, and can use stored energy for DL ​​and / or UL signal amplification. It should be noted that Device-A / B: The modulation and demodulation methods that can be used are relatively simple, such as OOK (On-Off Keying) / PSK (Phase Shift Keying), etc. (3) Device-C: Has energy storage capability and can generate signals independently, for example, has an RF (Radio Frequency) module that actively transmits signals. Device-C can also use more complex modulation and coding methods, such as OFDM (Orthogonal Frequency Division Multiplexing) modulation and demodulation, and can amplify uplink or downlink signals.

[0159] It should be noted that among the three terminal types mentioned above, Device-C has the strongest capabilities, but also the highest hardware cost. Device-A has the weakest capabilities, but also the lowest hardware cost. Because Device-A / B can only use backscattering mode and cannot actively transmit signals, they require external CW (continuous wave) for backscattering when they need to transmit information. Therefore, their coverage area is relatively small. However, Device-A / B consumes less power than Device-C.

[0160] In some embodiments, for Device-A / B operating using backscattering, the terminal needs a CW node that provides continuous wave (CW) energy to support the electromagnetic waves for reflection while transmitting data. Typically, the CW has a constant amplitude. The CW node can be a standalone node or a network / intermediate node (e.g., UE, relay UE, etc.) communicating with the Device. The A-IoT device reflects the received CW, loading the signaling / data to be transmitted onto the reflected wave and sending it out. The reflected wave and the CW are at the same frequency or have a certain frequency offset. Simultaneously, the CW also powers the A-IoT device. When Device-A receives the wireless signal CW, it activates its internal receiving and processing module, which encodes and modulates the signaling / data to be uploaded by the A-IoT device, generating a transmission signal that is reflected back to the receiving terminal.

[0161] In some embodiments, new A-IoT terminal types can be configured in the new air interface communication system, such as IoT terminals that integrate sensing and communication. On the terminal side, a single hardware device can be used to simultaneously implement communication and sensing functions. The sensing function refers to the terminal sensing information such as the speed, angle, and distance of objects in its surrounding environment by sending sensing signals and receiving reflected waves from those signals. For example, in a wireless air interface communication system, there are six basic forms of sensing modes involved:

[0162] (1) The base station transmits and receives signals. The base station sends a sensing signal. After the sensing signal is reflected by the object being measured, the base station receives the reflected wave and uses the reflected wave to sense the object being measured.

[0163] (2) Base station A transmits and base station B receives. Base station A sends a sensing signal. After the sensing signal is reflected by the object being measured, base station B receives the reflected wave and uses the reflected wave to sense the object being measured.

[0164] (3) UE transmits and base station receives. The UE sends a sensing signal. After the sensing signal is reflected by the object under test, the base station receives the reflected wave and uses the reflected wave to sense the object under test.

[0165] (4) The base station sends a sensing signal, and after the sensing signal is reflected by the object under test, the UE receives the reflected wave and the UE senses the object under test based on the reflector wave.

[0166] (5) UE self-transmits and receives. The UE sends a sensing signal. After the sensing signal is reflected by the object under test, the UE receives the reflected wave and the UE senses the object under test based on the reflector wave.

[0167] (6) UE-A transmits and UE-B receives. UE-A transmits a sensing signal. After the sensing signal is reflected by the object under test, UE-B receives the reflected wave and uses the wave from the reflector to sense the object under test.

[0168] For example, a device that receives a sensing signal corresponding to a reflected signal identifies the reflected signal and thereby extracts features of the object being measured, such as speed, angle, and distance.

[0169] In some embodiments, the sensing signal can be an OFDM (Orthogonal Frequency Division Multiplexing) waveform, or a new waveform, such as the product of a pulse waveform (or a continuous waveform) and its weight Fc (weighting factor), or a novel waveform formed by superimposing the product of an OFDM waveform and its weight Fr.

[0170] In some embodiments, the sequence length of the sensing signal transmission is N, and it can be a novel sequence used for sensing signal transmission. Examples include ZC (Zero-Crossing) sequences, gold sequences (pseudo-random sequences), M sequences (Maximum Length Sequences), Frank sequences, and so on.

[0171] In some embodiments, the sensing signal may be a novel signal specifically designed for the sensing process of the object being measured.

[0172] In some embodiments, the sensing signal can reuse reference signals from NR (New Radio). For example, when a base station transmits a sensing signal, the sensing signal can be an existing downlink reference signal in NR, such as DM-RS (Demodulation Reference Signal), CSI-RS (Channel State Information-Reference Signal), PTRS (Phase-tracking reference signals), PRS (Positioning Reference Signal), MRS (Mobility Reference Signal), and PSS / SSS (Primary Synchronization Signal / Secondary Synchronization Signal). If a UE transmits a sensing signal, the sensing signal can be DMRS (Demodulation Reference Signal) and SRS (Sounding Reference Signal) from NR.

[0173] In some embodiments, the sensing accuracy (the difference between the perceived value and the actual value; a smaller sensing accuracy indicates higher sensing accuracy) of the receiving end of the sensing signal (referring to the terminal receiving the reflected wave corresponding to the sensing signal) for distance, speed, and angle depends on the bandwidth occupied by the sensing signal and the SNR (Signal to Noise Ratio) value of the signal received by the receiving end of the sensing signal. For example, the sensing accuracy for distance depends on the transmission bandwidth of the sensing signal and the SNR value of the signal received by the receiving end of the sensing signal. When the transmission bandwidth of the sensing signal is larger, and / or the SNR value of the signal received by the receiving end of the sensing signal is larger, the sensing accuracy calculated according to the following formula is smaller, and the sensing accuracy is higher.

[0174] In some embodiments, Table 1 below shows the calculation method for the measurement accuracy of different sensing parameters:

[0175] For example, in the above sensing modes, the three modes of UE transmitting and gNB receiving, UE self-transmitting and self-receiving, and UE-A transmitting and UE-B receiving all involve the IoT terminal sending sensing signals. Typically, to improve sensing accuracy, a large bandwidth is needed for the sensing signal; for example, the transmission bandwidth of the sensing signal is 400MHz. In positioning, to improve positioning accuracy, the bandwidth of the PRB is equal to the bandwidth of the entire BWP.

[0176] In some embodiments, IoT systems are characterized by bandwidth limitations, with a relatively small operating bandwidth. For example, the operating bandwidth of an IoT system may not exceed 20MHz. If the sensing signal occupies only a portion of the total system bandwidth (e.g., 10MHz), the transmission bandwidth of the sensing signal is also limited. Therefore, it is necessary to consider how to improve the sensing accuracy of quantities such as distance, speed, and angle under narrowband IoT operation.

[0177] It should be noted that, based on Table 1 above, the sensing accuracy is related to the SNR value of the reflected signal corresponding to the sensing signal received by the sensing receiver. A higher SNR value results in higher sensing accuracy, and it is also related to the bandwidth occupied by the sensing signal; a wider bandwidth leads to higher sensing accuracy. Therefore, in this embodiment, sensing accuracy is improved by increasing both the SNR value and the bandwidth of the sensing signal.

[0178] Figure 2 is an interactive schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 2, the embodiments of the present disclosure relate to a communication method, which includes:

[0179] In step S2101, the terminal determines the first transmission resource for the sensed signal.

[0180] In some embodiments, the first transmission resource is used to transmit sensing signals, and the terminal transmits sensing signals to the target device based on the first transmission resource.

[0181] In some embodiments, the first transmission resource may be a time-domain resource used to indicate the transmission time period or time range of the sensing signal. There may be multiple time periods or time ranges to indicate that the terminal can transmit the sensing signal within multiple time periods.

[0182] For example, the multiple transmission time periods can be consecutive or spaced apart. The terminal can freely configure these based on the urgency of signal transmission in the current network environment, thereby improving signal transmission efficiency.

[0183] In some embodiments, the first transmission resource may be a frequency domain resource, used to indicate the transmission frequency domain segment or transmission frequency domain range of the sensing signal. The transmission frequency domain segment or transmission frequency domain range may be multiple, used to indicate that the terminal can transmit the sensing signal in multiple frequency domain segments.

[0184] For example, these multiple frequency domain resources can be contiguous in the frequency domain or frequency domain resources with frequency intervals. The terminal can configure them based on the signal interference situation in the current network environment. For instance, if the signal interference in the current network environment is strong, frequency domain resources with frequency intervals can be used to transmit the sensing signal in segments. If the signal interference in the current network environment is weak, frequency domain resources without frequency intervals can be used to transmit the sensing signal.

[0185] In some embodiments, the name of the first transmission resource is not limited, and it may be, for example, "sensing signal transmission resource", "frequency hopping transmission resource", "sensing transmission resource", etc.

[0186] In some embodiments, the first transmission resource includes time-domain resources in N different time periods and frequency-domain resources in N different frequency domains, where N is an integer.

[0187] For example, in this embodiment, the first transmission resource is used to transmit the sensing signal emitted by the terminal. This first transmission resource comprises time-domain resources within N different time periods, and can also comprise N different frequency-domain resources, where N is an integer. That is, the sensing signal is transmitted via frequency hopping in both the frequency and time domains based on the first transmission resource, transmitting the sensing signal within different time periods and / or using different frequency-domain resources. For instance, the terminal can transmit the sensing signal within N different time periods, thereby avoiding periods with strong signal interference and transmitting the sensing signal within N different time periods with weaker interference, thus improving the SNR value during the sensing signal transmission process and enhancing the sensing accuracy at the sensing signal receiver. There may or may not be a time interval between the N time periods. In this embodiment, the time interval between the N time periods is not limited when a time interval exists.

[0188] The terminal can transmit sensing signals on N different frequency domain resources, thereby reducing the possibility of sensing signal fading, enhancing the anti-fading capability during sensing signal transmission, and improving the sensing accuracy of the sensing receiver.

[0189] In step S2102, the terminal sends a sensing signal to the target device based on the first transmission resource.

[0190] In some embodiments, the target device receives sensing signals.

[0191] In some embodiments, the target device is a device being detected, such as an A-IoT device. The terminal sends a sensing signal to the target device, which reflects the received sensing signal, generating an echo signal that is reflected back to the first device. The first device detects the sensing data of the target device based on the echo signal to obtain the sensing information of the target device. This sensing information includes the target device's position, speed, direction, and angle information.

[0192] In some embodiments, the echo signal is used to determine the sensing information of the target device, the sensing information including at least one of the following: distance information, angle information, speed information, and position information.

[0193] For example, the first device is a device that receives echo signals and analyzes the echo signals to generate sensing information for the target device. Based on the various sensing scenarios in the above embodiments, the first device can be a base station, corresponding to a sensing scenario where the terminal sends a sensing signal and the base station receives the echo signal to detect the sensing information; the first device can also be other terminals, corresponding to a scenario where UE-A sends a sensing signal and UE-B receives the sensing signal; the first device can also be a terminal that sends a sensing signal, corresponding to a scenario where UE-A sends a sensing signal and UE-A receives the sensing signal.

[0194] In some embodiments, the sensing signal is used to detect sensing information of the target device. The terminal sends out the sensing signal, the target device reflects the sensing signal to generate an echo signal, and the target device sends the echo signal to the first device.

[0195] In some embodiments, the waveform of the sensed signal is a set waveform, which is the product of a pulse waveform and a first weight, or the set waveform is the product of an orthogonal frequency division multiplexing (OFDM) waveform and a second weight.

[0196] For example, in this embodiment, the waveform of the sensed signal can be a set waveform, which is a pulse waveform and a first weight F. c The product between them, thus creating a new waveform form to carry the sensing signal, thereby utilizing the advantage of pulse waveforms in time resolution for the transmission of the sensing signal, through the first weight F c It can flexibly optimize the waveform of the sensed signal to adapt to different communication and sensing needs.

[0197] The waveform of the sensed signal can also be an OFDM waveform and a second weight F. r The new waveform formed by the product of the two is used to transmit the sensing signal by taking advantage of the spectral efficiency of the OFDM waveform, so that the sensing signal has better anti-interference performance and improves the transmission efficiency of the sensing signal.

[0198] In this embodiment, the high spectral efficiency of OFDM waveforms is combined with the high precision characteristics of pulse waveforms to improve the transmission efficiency and anti-interference capability of sensing signals, and ensure the communication performance during the transmission of sensing signals.

[0199] In some embodiments, the sensing signal is a sensing sequence signal, which includes at least one of the following: ZC sequence signal, gold sequence signal, M sequence signal, and Frank sequence signal.

[0200] For example, in this embodiment, the sensing signal is transmitted in the form of a sequence signal, which can improve the anti-interference capability against external interference and improve spectrum utilization. By using the sequence transmission method, the positioning accuracy during the sensing process can be improved by utilizing the characteristics of the sequence signal, ensuring the reliability of the sensing signal. The sequence form of the sensing signal can be: ZC sequence, gold sequence signal, M sequence signal, or Frank sequence signal. By utilizing the relevant characteristics of the above sequence signals during transmission, the anti-interference capability of the sensing signal can be improved.

[0201] In some embodiments, step S2101 above includes:

[0202] Based on the first transmission resource, the terminal sends sensing signals to the target device through N frequency domain resources in N different time periods.

[0203] For example, the first transmission resource includes time-domain resources within N different time periods and frequency-domain resources in N different frequency domains. When the terminal sends a sensing signal to the target device based on the first transmission resource, it can use frequency hopping transmission to send the sensing signal. Within the N different time periods, N frequency-domain resources are used to send the sensing signal to the target device. For example, if N is 3, when the terminal sends a sensing signal based on the first transmission resource, it uses frequency-domain resource f1 to transmit the sensing signal within time period t1, frequency-domain resource f2 to transmit the sensing signal within time period t2, and frequency-domain resource f3 to transmit the sensing signal within time period t3.

[0204] In some embodiments, N is determined by at least one of the following: predefined information, preconfiguration information, and control signaling information.

[0205] For example, N is the number of frequency hopping during the frequency hopping transmission of the sensing signal. In this embodiment, the value of N can be determined by predefined information, preconfiguration information, and control signaling information sent by the base station.

[0206] In some embodiments, among the N frequency domain resources, each frequency domain resource is a continuous bandwidth of BW in the frequency domain. For example, when N is 2, a sensing signal is transmitted on the continuous bandwidth of frequency domain resource f1 with BW in time period t1, and a sensing signal is transmitted on the continuous bandwidth of frequency domain resource f2 with BW in time period t2.

[0207] In some embodiments, the frequency interval between N frequency domain resources in adjacent time periods is X, where X is an integer.

[0208] For example, in N frequency domain resources, the frequency interval between adjacent frequency domain resources within the frequency domain is X, where X is an integer. For instance, when X = 0, it represents a frequency domain resource f that is frequency hopping. x and frequency domain resources f x+1 There is no frequency domain interval between them; when X > 0, the frequency domain resource f x and frequency domain resources f x+1 The frequency difference between them is X (kHz / MHz).

[0209] In some embodiments, X is t X Frequency domain resources f within the time period X The lowest frequency domain value, and t X+1 Frequency domain resources f within the time period X+1 The absolute difference between the highest frequency domain values. Where, t X Time period and t X+1 The time period is an adjacent time period, and the frequency domain resource f X For t X The Xth frequency domain resource corresponding to the time period, frequency domain resource f X+1 For t X+1 The (X+1)th frequency domain resource corresponding to the time period.

[0210] For example, in this embodiment, X represents the absolute difference between the lowest and highest frequency domain values ​​for two corresponding frequency domain resources within two adjacent time periods. For example, t X Frequency domain resources f within the time period X The lowest frequency domain value, and t X+1 Frequency domain resources f within the time period X+1 The absolute difference between the highest frequency domain values ​​is X, where t X Time period and t X+1 The time period is an adjacent time period among N time periods, and the frequency domain resource f X For t X Frequency domain resources corresponding to the time period, frequency domain resources f X+1 For t X+1 Frequency domain resources corresponding to the time period.

[0211] It should be noted that among the N frequency domain resources that correspond one-to-one within N time periods, the frequency domain interval X between corresponding frequency domain resources in adjacent time periods can be the same or different. In this embodiment, the terminal can configure the corresponding frequency domain interval for each adjacent time period based on the current network environment, and this embodiment does not impose any limitations on this.

[0212] In some embodiments, X is determined by at least one of the following: predefined information, preconfiguration information, and control signaling information.

[0213] For example, X can be configured using predefined, preconfigured, and base station control signaling configuration methods.

[0214] In some embodiments, the time interval between two adjacent time periods within N time periods is Y, where Y≥0.

[0215] For example, the time interval between adjacent time periods in N time periods is Y, where Y≥0. For instance, there may be no time interval between time periods t1 and t2, or there may be a certain time interval, which can be set according to the anti-interference capability of the current network environment of the terminal.

[0216] In some embodiments, Y > 0, Y > a set time interval, where the set time interval is the coherence time of the mobile channel.

[0217] For example, in this embodiment, there is a time interval between adjacent time periods within the N time periods, and this time interval is greater than the correlation time of the mobile channel. The coherence time is the time interval during which the channel characteristics in the communication system remain relatively unchanged. By setting the time interval during frequency hopping transmission in the sensing signal transmission process, the sensing signal, after being reflected by the target device, receives incoherent fading signals in the first device at the sensing signal receiving end. This achieves the purpose of diversity transmission of the sensing signal in the time domain and improves the anti-interference capability of the sensing signal during transmission.

[0218] In some embodiments, the first transmission resource includes a second transmission resource and a third transmission resource, wherein the transmission resource bandwidth of the second transmission resource is the system bandwidth and the transmission resource bandwidth of the third transmission resource is the shared bandwidth.

[0219] For example, in this embodiment, the sensing accuracy during the sensing transmission process is enhanced by increasing the sensing signal transmission bandwidth. The first transmission resource includes a second transmission resource and a third transmission resource. The second transmission resource is the system bandwidth for the terminal to transmit sensing signals, and the third transmission resource is the shared bandwidth in the communication system. When transmitting sensing signals, the terminal can use the second transmission resource + the third transmission resource to send the sensing signal. For example, if the sensing signal bandwidth allocated within the system bandwidth (operating bandwidth) of the IoT device is XKhz, and a shared bandwidth of TKhz is set, the terminal can use the bandwidth resource of XKhz + TKhz to send the sensing signal. The first transmission resource can be the full system bandwidth or a portion of the system bandwidth corresponding to the terminal.

[0220] In some embodiments, the first transmission resource includes a second transmission resource and a fourth transmission resource, wherein the transmission resource bandwidth of the second transmission resource is the system bandwidth and the transmission resource bandwidth of the fourth transmission resource is the protection bandwidth.

[0221] For example, the first transmission resource includes a second transmission resource and a fourth transmission resource. The second transmission resource is the terminal's system bandwidth, and the fourth transmission resource is a protection bandwidth. In this embodiment, the sensing accuracy is improved by increasing the transmission bandwidth. When the terminal sends a sensing signal, the sensing signal is carried by both the terminal's system bandwidth and the communication system's protection bandwidth. The protection bandwidth is placed between two adjacent channels to reduce or avoid mutual interference between adjacent channels. In the communication system, by setting protection bandwidth between channels, signal attenuation caused by channel frequency selectivity is reduced. In this embodiment, the protection bandwidth is used to jointly transmit the sensing signal, thereby increasing the transmission bandwidth during the sensing signal transmission process. The protection bandwidth between channels in the communication system is used as the fourth transmission resource. The sensing signal is sent through the second and fourth transmission resources, thereby improving the utilization rate of system transmission resources and improving sensing accuracy.

[0222] In some embodiments, the fourth transport resource includes at least one of the following:

[0223] Protected bandwidth resources between the uplink and downlink;

[0224] Protecting bandwidth resources between different devices;

[0225] Protect bandwidth resources between different communication systems.

[0226] For example, in this embodiment, the fourth transmission resource is the protection bandwidth in the communication system. The protection bandwidth can be: (1) the protection bandwidth resource between UL (Up-Link) and DL (Down Link) in the communication system; (2) the protection bandwidth resource during the transmission of sensing signals between different terminals; (3) the protection bandwidth resource between different communication systems, such as the protection bandwidth resource between a 5G communication system and a 6G communication system, or the protection bandwidth resource between a 6G communication system and a 4G communication system.

[0227] In this embodiment, the fourth sensing resource can be part or all of the frequency domain resources in the protection bandwidth resources. When the sensing signal is transmitted together with the second transmission resource through the fourth transmission resource, the remaining frequency domain resources in the fourth transmission resource can be used as a PRB, a protection resource block, or a protection unit.

[0228] In some embodiments, step S2102 above includes:

[0229] Within a set time period, the terminal sends sensing signals to the target device through the second and third transmission resources, and the set time period is the shared time period of the third transmission resources.

[0230] For example, to avoid communication disruptions caused by the abuse of shared bandwidth, this embodiment transmits sensing signals through the second and third transmission resources within a set time period. This set time period is the shared time period of the third transmission resource. During the shared time period of the third transmission resource, the terminal can transmit sensing signals through the second and third transmission resources; outside the shared time period, the terminal cannot use the third transmission resource to transmit sensing signals.

[0231] In some embodiments, the fourth transmission resource corresponds to a shared time period, during which the terminal can use the fourth transmission resource and the first transmission resource to transmit sensing signals.

[0232] In some embodiments, the time period is determined by at least one of the following: predefined information, preconfiguration information, and control signaling information.

[0233] For example, the shared time of the third and / or fourth transport resources can be determined through predefined information, preconfiguration information, and control signaling information.

[0234] In some embodiments, the time period is set as periodic configuration information.

[0235] For example, the terminal can periodically transmit sensing signals through third and / or fourth transmission resources based on the periodic configuration characteristics of a set time period.

[0236] In step S2103, the target device reflects an echo signal back to the first device based on the received sensing signal.

[0237] For example, the target device is the sensed device. The terminal sends a sensing signal to the target device. The target device reflects the received sensing signal and generates an echo signal, which is sent to the first device. The first device analyzes the target device based on the reflected signal to determine the sensing information of the target device. This sensing information includes the target device's position information, angle information, direction information, and speed information, etc.

[0238] In step S2104, the first device performs merging processing on the received echo signals and determines the sensing information of the target device based on the merged echo signals.

[0239] For example, in this embodiment, the echo signal corresponds to the sensing signal sent by the terminal. That is, the echo signal received by the first device is an echo signal on N frequency domain resources within N different time periods. The first device can receive the echo signal based on the second and third transmission resources, or the first device can receive the echo signal based on the second and fourth transmission resources. The first device merges the echo signals received on the N frequency domain resources within the N different time periods to obtain the target echo signal, and then analyzes the target echo signal to obtain the sensing information of the target device.

[0240] In some embodiments, the first device may combine multiple received echo signals using gain combining or maximum ratio combining. In this embodiment, the combining method of the first device is not limited.

[0282] Figure 5A is a flowchart illustrating a communication method according to an embodiment of the present disclosure. As shown in Figure 5A, the embodiment of the present disclosure relates to a communication method executed by a terminal, the method including:

[0283] Step S5101: During N different time periods, send sensing signals to the target device through N frequency domain resources.

[0284] In some embodiments, the transmission of the sensing signal adopts a new waveform, such as a new waveform formed by superimposing the product of a pulse waveform (radar waveform) and its weight Fc, or a new waveform formed by superimposing the product of an OFDM waveform and its weight Fr.

[0285] In some embodiments, the sensing signal is sent by the terminal. When the sensing signal encounters a sensed device in the environment, it generates a corresponding reflected signal, which is received by the sensing signal receiver. Based on the reflected signal, the sensing signal receiver determines the channel H, noise statistics, etc., and calculates sensing information such as the distance, angle, and speed of the sensed device in the surrounding environment using a sensing algorithm.

[0286] In some embodiments, the sensing signal can be in the form of a sequence with a length of M. The sequence form corresponding to the sensing signal can be a novel sequence signal specifically designed for sensing; it can also be a ZC sequence, gold sequence, M sequence, Frank sequence, etc., which are not limited in this embodiment.

[0287] In some embodiments, the transmission of the sensing signal uses frequency hopping technology, employing N hops. When the bandwidth allocated to the sensing signal is the full BW (Bandwidth Resource), it is transmitted on frequency domain resource f1 within time period t1, on frequency domain resource f2 within time period t2, and so on, within time period t... N Intrinsic frequency domain resources f N Send it up. Among them, frequency domain resource f1 and frequency domain resource f NLocated on the same carrier, multiple frequency domain resources f1-f N The bandwidth in the frequency domain is BW resource. It should be noted that frequency hopping technology, when the frequency interval of frequency hopping is greater than the channel correlation bandwidth, can make the signals in each frequency hopping dwell time independent of each other. This means that the possibility of fading occurring simultaneously at different frequencies is very low, which can resist multipath fading and has strong anti-fading capability. N is an integer.

[0288] In some embodiments, the receiver of the reflected signal corresponding to the sensed signal needs to process the time period t1 - time period t. N Multiple reflected signals received internally can be combined using methods such as optimal selection combining, equal gain combining, and maximum ratio combining.

[0289] In some embodiments, other alternative implementations may be described before or after the specification corresponding to FIG5A.

[0290] Figure 5B is a schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 5B, N=3. A sensing signal is transmitted over a continuous bandwidth of frequency domain resource f1 (BW) during time period t1, over a continuous bandwidth of frequency domain resource f2 (BW) during time period t2, and over a continuous bandwidth of frequency domain resource f3 (BW) during time period t3. The receiving device merges the three reflected signals received during time periods t1, t2, and t3 to generate a single reflected signal. This reflected signal is then analyzed to obtain the sensing information of the target device.

[0291] In some embodiments, within N time periods, there may be no time interval between adjacent time periods t1 and t2, or there may be a certain time interval. When there is a time interval between adjacent time periods, the interval can be greater than the coherence time of the mobile channel (the time interval during which the characteristics of the channel remain relatively unchanged), thereby enabling the receiver to obtain uncorrelated fading signals, achieving the purpose of time diversity and improving the anti-interference capability of the sensed signal.

[0292] In some embodiments, the frequency interval between adjacent frequency domain resources f1 and f2 in N frequency domain resources is X. That is, in the frequency domain resources corresponding to adjacent time periods, the frequency interval between the highest frequency value in the lower frequency domain resource f1 and the lowest frequency domain value in the higher frequency domain resource f2 is X kHz or X MHz. Here, the frequency interval X is predefined, preconfigured, or dynamically indicated by control signaling, and the value of X is an integer. When X = 0, it indicates that there is no frequency interval between adjacent frequency domain resources f1 and f2 during frequency hopping transmission.

[0293] In some embodiments, the N value is predefined or preconfigured, or dynamically indicated by control signaling.

[0294] Figure 5C is a schematic diagram of a sensing signal transmission method according to an embodiment of the present disclosure. As shown in Figure 5C, the terminal transmits the sensing signal using frequency hopping transmission. In this embodiment, the sensing signal transmission uses 2 hops, N=2, corresponding to continuous transmission with a bandwidth of BW on frequency domain resource f1 within time period t1, and continuous transmission with a bandwidth of BW on frequency domain resource f2 within time period t2. For example, if the terminal is an IoT device with a system bandwidth of 20MHz, the transmission of the sensing signal occupies the entire system bandwidth; within time period t1, the sensing signal is transmitted with a continuous bandwidth of 20MHz on frequency f1, and within time period t2, it is transmitted with a continuous bandwidth of 20MHz on frequency f2.

[0296] Step S5201: Send a sensing signal to the target device using the system bandwidth and shared bandwidth.

[0297] In some embodiments, in addition to the bandwidth X MHz / kHz of the sensing signal allocated within the system bandwidth (operating bandwidth) of the IoT device, a shared bandwidth of T MHz / kHz is configured in the sensing communication system, and the terminal can operate within a preset time period t. x The system uses the shared bandwidth to send sensing signals through the system bandwidth and the common bandwidth. The bandwidth that the sensing signals can use is T mhz + X mhz or T Khz + X Khz.

[0298] In some embodiments, transmitting sensing signals includes sending sensing signals or receiving sensing signals.

[0299] In some embodiments, a preset time period t x It is either predefined or preconfigured by network devices, or dynamically indicated by control signaling.

[0300] In some embodiments, the shared bandwidth can be a shared bandwidth between IoT systems and non-IoT systems. During a specific time period t... x In addition, shared bandwidth is used to transmit non-IoT information, such as reporting information sent by terminals to network devices.

[0301] In some embodiments, the frequency domain information of the shared bandwidth is determined by a method that is predefined or preconfigured by network devices or dynamically indicated by control signaling. The frequency domain information includes at least one of the following: the frequency domain range of the shared bandwidth, the frequency domain start position, the frequency domain end position, and the number of frequency domain resource units.

[0302] By utilizing the above method, the bandwidth during the transmission of sensing signals is increased by sharing bandwidth, thereby improving sensing accuracy.

[0306] In some embodiments, the protection bandwidth resources are used to transmit sensing signals, and the terminal can only transmit signals within a preset time period t. x It uses protected bandwidth resources to transmit sensing signals.

[0307] In some embodiments, a preset time period t x It is either predefined or preconfigured by network devices, or dynamically indicated by control signaling.

[0308] In some embodiments, a preset time period t x It is configured periodically.

[0309] In some embodiments, the transmission includes the terminal sending a sensing signal and the receiving end receiving a reflected signal corresponding to the sensing signal.

[0311] In some embodiments, the terminal during a preset time period t x The sensing signal is transmitted using some or all of the frequency domain resources in the protection bandwidth, while the remaining frequency domain resources in the protection bandwidth are still used as protection bandwidth, PRB, protection resource block or protection unit.

[0312] By utilizing the above methods, the bandwidth during the transmission of sensing signals is increased through the use of protection bandwidth, thereby improving sensing accuracy.

[0313] In some embodiments, other alternative implementations may be described before or after the specification corresponding to FIG5E.
