[0360] The signal transmission method provided by the embodiments of this disclosure mainly involves the time-frequency domain resource allocation of AIoT signals, the granularity division of time / frequency resources, and the behavior of AIoT devices receiving and / or sending AIoT signals. The specific process is as follows:

[0361] First, the AIoT device can obtain relevant information about dedicated resources for receiving and / or sending AIoT signals (i.e., resource-related information) through at least one method such as protocol agreement, AIoT signal transmission, and pre-stored information. The resource-related information used for receiving and / or sending AIoT signals includes at least one of the following:

[0362] AIoT signals may include: at least one of the receiving signal and / or the transmitting signal of the AIoT device. For example, the receiving signal of the AIoT device may include a query signal and / or an excitation signal carrying command information, etc. The two may be the same signal or two independent signals. The transmitting signal of the AIoT device may include a reflected signal and / or a transmitting signal generated by itself;

[0363] The relevant information about the time domain resources where the AIoT signal is located may include: at least one of the following relevant information: start time, end time, duration, time domain unit, etc.; wherein, the relevant information about the time domain where the AIoT signal is located may be independent of the time domain of the NR signal, and the relevant information about the time domain where the AIoT signal is located is associated with the NR signal. For example, the time domain resource unit of the AIoT signal is N times or 1 / N of the time domain resource unit of the NR signal, where N is an integer greater than or equal to 1;

[0364] The transmission method of the query signal and the stimulus signal in the AIoT signal, and / or the relationship between the time domain resources of the two, such as: having a specific time interval or receiving them simultaneously;

[0365] The manner in which the AIoT device reflects or sends a response signal, and / or its temporal correlation with the received AIoT signal, such as having a specific time interval, where the specific time interval is greater than or equal to 0;

[0366] The relevant information of the frequency domain resources where the AIoT signal is located may include: at least one item such as the bandwidth of the frequency domain resources, the frequency domain resource unit, and the spectrum interval between the frequency domain bandwidths. It can be independent of the NR spectrum resources or have an associated relationship with the NR spectrum resources, that is, the spectrum resource boundaries are aligned.

[0367] It should be noted that the base station or intermediate node (which may be a relay device located between the first device and the base station, etc.) sends an AIoT signal carrying resource-related information to the AIoT device. In this way, the AIoT device can obtain resource-related information from the signal sent by the base station or intermediate node, where the resource-related information includes at least one of the following:

[0368] Relevant information about the time domain resource where the AIoT signal is located, including at least one of the following: start time, end time, duration, time domain unit, etc.

[0369] The transmission method of the query signal and the stimulus signal in the AIoT signal, and / or the correlation between the time domain resources of the two;

[0370] The way in which the AIoT device reflects or sends a response signal, and / or its time domain correlation with the received AIoT signal.

[0371] Secondly, the AIoT device can receive AIoT signals based on the obtained time-frequency resource related information, or receive AIoT signals in a specific frequency band according to a specific time period, or continuously detect and receive AIoT signals in a specific frequency band.

[0372] The starting point, ending point, duration, and time domain resource unit of the AIoT signal can be obtained through the preamble or synchronization sequence of the AIoT signal, or can be learned based on whether a specific signal is received, such as receiving a query signal carrying specific information;

[0373] The specific frequency band where the AIoT signal is located, for example: the AIoT signal carrying command information is received in the full frequency band or part of the frequency band of the NR FDD uplink (Uplink, UL), and / or is received in the full frequency band of the NR TDD UL; the AIoT signal carrying the carrier signal is received in part of the frequency point of the NR FDD UL, and / or is received in the full-duplex UL frequency point of NR TDD.

[0374] Furthermore, the AIoT device can perform backscattering based on the command information carried by the received AIoT signal and / or based on the AIoT signal carrying the excitation information, or the AIoT device can send the AIoT signal based on the time domain resource information. Among them, the resource-related information of the time-frequency resources for the AIoT device to reflect or send the AIoT signal can be obtained by interpreting the query signal carrying the command information, or it can be obtained through specific calculation based on the AIoT device attribute information, such as: device identification (Identity, ID). Here, the specific calculation can be a modulus calculation.

[0375] In addition, the base station can instruct non-AIoT devices (for example, terminal devices) through high-layer signaling configuration or downlink control signaling not to receive and / or send all or part of the existing signals / channels / messages within the time window and frequency band for receiving and / or sending AIoT signals.

[0376] When non-AIoT devices receive high-level signaling configuration or downlink control signaling indicating the reception and / or transmission of AIoT signals within the time-frequency resources, they do not receive and / or transmit or only partially receive and / or transmit signals / channels / messages that have been configured or agreed upon by the protocol.

[0377] Example 1: AIoT time domain resources - no correlation with NR time domain resources.

[0378] When the transceiver of the AIoT signal is independent of the transceiver of the NR signal, and the receiving and / or sending signal process of the AIoT signal is independent of the receiving and / or sending signal process of the NR device in terms of time domain resources and there is no interference, then the time domain resource division of the AIoT has no correlation with the time domain resource division of the NR.

[0379] For example, when the AIoT signal is used in the protection band of the NR / LTE system or has a separate frequency band, the transceiver of the AIoT signal is independent of the transceiver of the NR signal, and the time domain resource division of the AIoT is unrelated to the time domain resource division of the NR, as shown in Figure 4.

[0380] AIoT's time domain resources are unrelated to NR's time domain resources. For example, the time domain resource units used in AIoT signal transmission are independent of NR's time domain sub-resource units. A time domain resource unit can include at least one of a symbol, a time slot, a subframe, or a data frame.

[0381] AIoT signals include at least one of an AIoT device's received signal and / or transmitted signal. For example, an AIoT device's received signal may be a query signal and / or an excitation signal carrying command information. These signals may be the same or separate. An AIoT device's transmitted signal may be a reflected signal and / or a transmitted signal.

[0382] The AIoT signal transmission process includes: at least one of an AIoT signal receiving process and / or a sending process.

[0383] The time domain unit of an AIoT signal is related to at least one of the payload, coding, and modulation of the AIoT signal. The payload of an AIoT signal indicates the information carried by the AIoT signal, or fixed sequence information. The AIoT signal can be obtained through at least one of protocol agreement, synchronous detection, or signaling.

[0384] For the purpose of explanation, the following example illustrates the transmission process of an AIoT signal, specifically including one or more of the following:

[0385] First, the AIoT signal includes a query signal and / or an excitation signal, wherein the AIoT signal may carry at least one of synchronization sequence information, signal-carried command information, carrier frequency information, and carrier waveform;

[0386] AIoT devices obtain information related to resources received and / or sent by AIoT signals through at least one of the following methods: protocol agreement, AIoT signal transmission, pre-stored information, etc.

[0387] The resource-related information of the exclusive resources for receiving and / or sending AIoT signals includes: at least one of the related information such as the start time, end time, and duration of the time domain information of the AIoT signal. For example, the start time / end time includes: the time reference point of reception / transmission, the time deviation between reception / transmission and the time reference point, the reception / transmission time point, the reception / transmission duration, etc. Among them, the time domain resources of the AIoT signal are independent of each other and the NR time domain resources, that is, the start time / end time of the AIoT signal can be aligned with the boundary of the NR time domain resource unit or not. The misalignment means that it is sent at any time. The division of the time domain resource unit for receiving / sending AIoT signals is independent of the division of the NR resource unit and has no correlation. The start time, end time and duration can be directly indicated by a numerical value, or can be indicated by whether the AIoT signal is received or sent.

[0388] The resource-related information of the dedicated resources for receiving and / or sending AIoT signals also includes: the sending method of the query signal and the excitation signal and / or the correlation between the time domain resources of the two.

[0389] When the query signal and the excitation signal are two independent signals, the time domain resource related information can be configured independently, or only one of them can be configured, such as the query signal or the excitation signal. In addition, the two can also have a certain temporal correlation, such as the AIoT device receives the query signal first and then the excitation signal, and there is a certain time interval between the two reception times.

[0390] When the query signal and the stimulus signal are the same signal, the time domain resource related information is only for one of them, such as: the query signal. The stimulus signal is located after the query signal and separated by a specific time interval. The specific time interval is greater than or equal to 0;

[0391] Resource-related information about dedicated resources for receiving and / or transmitting AIoT signals also includes: how the AIoT device reflects or sends response signals. For example, after detecting a query signal carrying command information, the AIoT device may reflect or send a query signal, and / or reflect or send one or more response signals to the query signal, and / or stop reflecting or sending response signals to the query signal.

[0392] The timing relationship of the AIoT device receiving / sending the query signal and / or the reflected signal within the time domain resources of receiving and / or sending the AIoT signal is shown in Figure 5. The time interval Gap between each query signal and the reflected signal can be obtained through at least one of the following methods: protocol agreement, AIoT signal carrying, or pre-stored information.

[0393] Secondly, the AIoT device receives the AIoT signal based on the resource-related information obtained, either according to a specific time period or continuously detecting and receiving the AIoT signal. The starting point, end point, duration, and time unit of the AIoT signal can be obtained through the preamble of the AIoT signal.

[0394] The process of an AIoT device receiving an AIoT signal includes at least one of the following situations:

[0395] When an AIoT device can obtain timing information, it can receive AIoT signals based on the specific time resource information it obtains. For example, an AIoT device can determine the starting position of an AIoT signal based on its amplitude, then determine the duration of the time domain unit based on the AIoT preamble sequence. This allows it to receive the complete AIoT signal based on the duration of the AIoT signal. Furthermore, if the time intervals between different signals are configured, the corresponding response signal can be reflected or transmitted at specific time points.

[0396] AIoT devices can receive signals for a period of time every 30 seconds based on a specific time period, such as a 30-second period. The specific time interval is based on a protocol agreement or time interval information obtained based on the AIoT signal. For example, the AIoT device periodically receives / sends AIoT signals based on its own clock. The starting point, end point, and duration of the AIoT signal can be determined based on the preamble of the AIoT signal. The specific time period is related to the sequence length of the AIoT signal, and the specific value is greater than or equal to the symbol length of the AIoT signal × the number of symbols of the AIoT signal + the time interval between adjacent AIoT signals.

[0397] For example, an AIoT device can determine the reception of an AIoT signal based on a specific signal trigger. For example, the AIoT continuously performs signal energy or amplitude detection. When the received signal meets a certain threshold value, this is the starting position for receiving / sending the signal.

[0398] Furthermore, the AIoT device performs backscattering based on the command information carried in the received AIoT signal and / or based on the AIoT signal carrying excitation information, or the AIoT device sends the AIoT signal based on the time domain resource information.

[0399] For example: Based on the received AIoT signal, the AIoT device parses the command information carried by the AIoT signal, such as: the specific sequence corresponding to the AIoT signal is the ID information of the feedback device, the device's own attribute information, the cache information or the response information, etc., then the AIoT device will feed back the command response information to the network at a specific time node based on the excitation signal.

[0400] For example, an AIoT device receives an AIoT signal, such as when it detects that the energy or amplitude of a signal meets a specific threshold value, and then backscatters the AIoT signal carrying the excitation information and feeds back the device-specific information to the network.

[0401] For example: the AIoT device sends an AIoT signal at a corresponding time point according to the time domain resource information, wherein the AIoT signal can be generated by the AIoT device itself.

[0402] It should also be noted that AIoT signals can also be transmitted within a specific time period, which needs to be aligned with the boundaries of the NR signal's time unit. This specific time period includes: an integer multiple of the AIoT signal's time domain unit or an integer multiple of the NR signal's time domain unit. This method can align AIoT signal transmission resources with NR's time domain resources, allowing non-AIoT device terminals to accurately obtain the corresponding AIoT signal transmission information.

[0403] Example 2: Time Domain Resource Division of AIoT — Related to NR

[0404] When the time domain resource units used by the AIoT to transmit and / or receive signals can be associated with those of the NR, the impact on the NR transceiver can be reduced. Here, the received signal of the AIoT device can be a signal carrying relevant information collection and / or function indication of the AIoT device, or a carrier signal used for backscattering of the AIoT device. The transmitted signal of the AIoT device can be a backscattered signal based on a carrier signal or an excitation signal.

[0405] The time domain resource unit of the AIoT signal is N times or 1 / N of the time domain resource unit of the NR signal, where the time domain resource unit includes: at least one of a symbol, a time slot, a subframe, or a data frame, or an AIoT-specific transmission time interval (TTI), where a TTI includes at least one AIoT symbol. The following example uses the symbol as the time domain unit of the AIoT signal as an example, for example:

[0406] The symbol length of the AIoT signal is 1 / N of the symbol length of the NR signal. Under 15kHz SCS, one symbol of the NR signal is 1 / 14ms, and the AIoT symbol length is 1NR symbol length / 2. k For example, the sequence length of the AIoT signal that can be transmitted in a 1ms time slot is shown in Table 4 below:

[0407] Table 4

[0408] The k value can be obtained by general protocol agreement, AIoT preamble sequence or synchronization sequence, AIoT device pre-stored information, etc. In addition, the symbol length T of the AIoT signal is sym , sequence length N sym , the time interval ΔT between the AIoT device receiving the signal and reflecting / sending the signal (transmitting signal), and the distance D between the AIoT device and the sending node F , the distance D between the AIoT device and the receiving node B The following relationship must be met to prevent the AIoT signal receiving node from being affected by self-interference: RTT +ΔT>=T sym *N sym ,;

[0409] Among them, T RTT represents the round trip time, (D F +D B ) / v+ΔT>=T sym *N sym , v is the speed of light.

[0410] For another example, as shown in Figure 6, the symbol length of the AIoT signal is 1 / M1 of the symbol length of the NR signal. The AIoT signal can use the OOK-4 signal: the N1 carriers (SC) of OOK-4 are generated by DFT / least squares transform, where: M1 = 4 information bits are processed by DFT / LS / FFT and time-frequency resource mapping, and then the AIoT signal is obtained by IFFT transform, where the symbol length of the AIoT signal is 1 / 4 of the symbol length of the NR signal.

[0411] Discrete Fourier Transform (DFT);

[0412] Fast Fourier Transform (FFT);

[0413] Least Squares (LS);

[0414] Inverse Fast Fourier Transform (IFFT);

[0415] This method can generate M1 AIoT symbols in 1 OFDM symbol, and the specific number of segments M1 of the OFDM symbol can be indicated by a query signal.

[0416] The above examples also apply to the time domain resource units of other AIoT signals. The start time, end time, and duration of AIoT signal reception / transmission are aligned with the boundaries of the NR signal time domain resource units, or have a certain nested relationship, as shown in Figure 7.

[0417] Example 3: Frequency domain resource allocation for AIoT - no correlation with NR spectrum.

[0418] The frequency domain resources where the AIoT signal is located can be independent frequency domain resources, such as within the NR protection band, or within an independent spectrum bandwidth.

[0419] Within the spectrum bandwidth of an AIoT signal, at least one sub-bandwidth can be divided to transmit the AIoT device's received signal and / or the AIoT reflected / transmitted signal. Different sub-bandwidths are separated by a certain guard interval. A specific implementation is shown in Figure 8, where the forward link represents the AIoT device's received signal, and the backward / backscatter signal represents the AIoT reflected / transmitted signal.

[0420] Specifically, it may include at least one of the following situations:

[0421] Case 1: The received signal of the AIoT device includes a query signal and / or an excitation signal, that is, the query signal and the excitation signal are in the same sub-bandwidth.

[0422] Case 2: The query signal received by the AIoT device is in a specific sub-bandwidth, and the excitation signal and the reflected / transmitted signal are in a specific sub-channel.

[0423] Case 3: The query signal, excitation signal, and reflected / transmitted signal received by the AIoT device are in different sub-bandwidths.

[0424] Case 4: The query signal and excitation signal received by the AIoT device are in the full broadband, and the excitation signal and the reflected / transmitted signal are in a specific sub-channel.

[0425] Case 5: The query signal, excitation signal, and reflected / transmitted signal received by the AIoT device are in at least one of the protection bands of the NR system or a frequency band independent of NR.

[0426] Case 6: The query signal and excitation signal received by the AIoT device are in at least one of the protection band of the NR system or a frequency band independent of NR, and the excitation signal and the reflected / transmitted signal are in a specific subchannel of the NR system.

[0427] It should be noted that when an AIoT device has a filter, it can receive the corresponding AIoT signal in a specific sub-band or in the full width.

[0428] Example 4: Frequency domain resource division of AIoT - nested with NR.

[0429] The operating bandwidth of AIoT is aligned with the frequency domain resource boundary of NR RB, including at least one of the following:

[0430] Case 1: The working bandwidth of AIoT is divided into channels based on the frequency domain resources of NR. The bandwidth is an integer multiple of RB, such as RB*N2.

[0431] Case 2: A new frequency domain resource partition unit F_0 is introduced, where the operating bandwidth of AIoT is F_0*M, which is an integer multiple of the subcarrier spacing, for example: F_0=RB / K, where K and M are positive integers;

[0432] Case 3: The operating bandwidth of AIoT is BW_AIoT, and there is a guard interval GB#A between it and the frequency domain bandwidth of NR. Through ΔBW, the operating bandwidth of AIoT + GB#A + ΔBW can be achieved, which is an integer multiple of RB.

[0433] Case 4: A new frequency domain resource division unit F_0 is introduced, and the working bandwidth of AIoT is F_0*M. There is a protection interval GB#A between it and the frequency domain bandwidth of NR. Through ΔBW (bandwidth adjustment parameter), the working bandwidth of AIoT + GB#A + ΔBW can be achieved, which is an integer multiple of the subcarrier spacing.

[0434] The following takes the above-mentioned case 2+case 4 as an example and describes it in combination with time-frequency resources, as shown in FIG9 .

[0435] Beneficial effect: The AIoT-related signals can be sent and received by relying on the NR signal transceiver structure in the related technology, which can simplify the design and reduce costs.

[0436] AIoT signals can also be used in the NR system spectrum to improve the utilization of authorized spectrum in related technologies.

[0437] As shown in Figure 10, when an AIoT sends and / or receives a signal in the NR FDD spectrum, at least one of the following situations may occur:

[0438] Case 1: The AIoT receiving signal (such as the query signal and / or the excitation signal) is in the NR FDD downlink spectrum;

[0439] Case 2: The AIoT receiving signal (e.g., query signal and / or excitation signal) is in the uplink spectrum of NR's FDD.

[0440] Case 3: AIoT sends signals (e.g., reflected or transmitted signals) in the NR FDD downlink spectrum;

[0441] Case 4: AIoT sends signals (e.g., reflected or transmitted signals) in the uplink spectrum of NR's FDD.

[0442] Beneficial effect: The AIoT query signal is sent in the FDD UL spectrum, reducing the interference of the downlink NR signal on the AIoT device. At the same time, AIoT devices without subband filters can also receive AIoT signals (such as query signals).

[0443] In addition, the query signal, excitation signal, and reflection / transmission signal contained in the AIoT signal can also be transmitted in the NR TDD system. Specifically, there are the following situations:

[0444] Case 1: When the AIoT device can obtain uplink and downlink time and frequency resource synchronization, the AIoT signal received by the AIoT device can be sent by the base station or intermediate node in the uplink time slot or downlink time slot within a specific time period. The AIoT signal sent by the AIoT device can be sent in the uplink time slot within a specific time period.

[0445] Case 2: Full-duplex with non-overlapping subbands, as shown in Figure 11. When the AIoT device can perform filtering, it can receive query signals and / or excitation signals on the uplink subband. The AIoT receives excitation signals and / or reflects or transmits AIoT signals on the full UL bandwidth, as shown in Figure 11.

[0446] Case 3: Full-duplex with no sub-band overlap, as shown in Figure 12. The AIoT receives query signals and / or excitation signals over the full UL bandwidth. It receives excitation signals and / or reflects or transmits AIoT signals over the uplink sub-band, as shown in Figure 12.

[0447] Through the solution of the embodiments of the present disclosure, the resource configuration and transmission method of AIoT devices applied in the NR system can be solved, so that the NR system can support AIoT device communication, utilize the NR spectrum, and improve spectrum utilization.
